Context 1: Passage 1:
The Miracle Child
The Miracle Child (French: L'enfant du miracle) is a 1932 French science fiction film based on a play of the same name by Robert Charvay and Paul Gavault  The plot of the film centers around a widow named Blanche Montel who endeavours to find a man with whom to produce a child so that she can pretend that the child was her late husband's and so inherit a fortune  In a scene which has been cited as particularly humorous, a few characters interrupt a Spiritualist séance and are subsequently believed to be ghosts  Ginette Leclerc's minor role in The Miracle Child was one of her first acting roles in a long and successful career 
Passage 2:
Blood Stain Child
Blood Stain Child (stylised as BLOOD STAIN CHILD) is a Japanese melodic death metal band from the city of Osaka  The band's musical style combines melodic death metal with electronic and trance  The band formed under the name "Visionquest" in 1999, but changed their name to Blood Stain Child in 2000 

Background
Blood Stain Child, then called Visionquest, was formed in 1999 by Ryo (bass, lead vocals), Ryu (lead guitar, synth guitar), Daiki (rhythm guitar, synth guitar), Aki (keyboards, piano, synthesizers, backing vocals) and Violator (drums, percussion)  In 2000, they took on their current name and recorded their first three-track demo in August 2000  The band sent that demo to a radio station and the DJ enjoyed the music so much that he recommended the band to the record label, M&I Company, who eventually signed Blood Stain Child In 2001, Blood Stain Child recorded two songs, "The World" and "Steel Flame"  The first song was used as the theme song for professional wrestler, Kensuke Sasaki and the second song was used as the theme song for the 30th anniversary of New Japan Pro-Wrestling, a professional wrestling group  In July 2002, Blood Stain released their debut studio album, Silence of Northern Hell  In October 2002, Blood Stain Child was the supporting act for Dream Evil during their tour in Japan  In June 2003, Blood Stain Child released their second studio album, Mystic Your Heart, which was co-produced by Anssi Kippo, a popular producer from Finland 
In March 2005, Daiki left the band and was replaced by Shiromasa in April  That same year, Blood Stain Child released their third studio album, Idolator, which was co-produced by Tue Madsen, a popular producer from Denmark  In 2006, Blood Stain Child signed with Dockyard 1 and released Idolator in Europe on 27 November 2006  Idolator was later released in the United States through Locomotive Records on 17 July 2007 
In April 2007, Blood Stain Child announced the addition of a new vocalist, Sadew, and a new guitarist, G S R  On 18 July 2007, Blood Stain Child released their fourth studio album, Mozaiq in Japan, which was also co-produced by Tue Madsen  It was then released in Europe on 20 July 2007 with an exclusive bonus track "Cosmic Highway" 
On 12 June 2010, Ryu announced on his official blog that Sadew withdrew from the band due to personal reasons  Drummer Violator left the band as well, in order to take care of family business  In September the band announced new members Sophia Aslanides (also known as Sophia Aslanidou, from Greece) on vocals and Gami (ex-Youthquake) on drums, signing a contract with Italian record label Coroner Records and Japanese record label Pony Canyon 
In April 2011, Blood Stain Child took part in a Studio Ghibli cover album titled Imaginary Flying Machines - Princess Ghibli, covering the songs "Itsumo Nando Demo" (Spirited Away) and "Teru no Uta" (Tales from Earthsea)  In June 2011, the band performed at A-Kon in Dallas, Texas, together with D  Later that same month, the band released their fifth full studio album, Epsilon  The band started a Japanese tour from 19 August to 24 September  In December 2011, the band performed in Moscow, St  Petersburg, Ekaterinburg and Kiev 
Blood Stain Child performed as special guests at Naka-Kon 2012, in Overland Park, Kansas, between the 10–12 February  In March 2012, the band took part in another Princess Ghibli album, covering the song "Ai wa Hana Kimi wa Sonotane" (Only Yesterday)  On 21 July, Sophia officially announced that she was leaving Blood Stain Child  She later formed the electronic metal band Season of Ghosts in 2013  New female vocalist Kiki joined the band on 3 December  In early 2013 the band introduced their new VJ/DJ - Makoto, which came along with an announcement of Aki being absent from further live shows due to "his personal issues", however, he will remain a member and take part in the creation of music  However, Makoto left in 2014 
Founding member Ryo and Kiki both left Blood Stain Child in 2016  They were replaced by bassist Yakky and male vocalist Saika, respectively In 2018, Blood Stain Child joined forces with Danceroid singer Yuzuki and created the melodic death metal supergroup Yuzukingdom 
On 1 February 2019, Blood Stain Child released a new single, entitled "Del-Sol" as well as an accompanying music video  Later that year, on 3 July, a new full-length album called Amateras was released featuring the same members as the previous single 

Musical style
A notable feature of Blood Stain Child is their tendency to incorporate both electro-industrial and euro-trance related themes and elements into their music  The band's sound includes screamed vocals complemented at times by traditional singing, with their overall musical style best classified as a mix between In Flames, Children of Bodom, and Soilwork  The band cites influences such as In Flames, Dark Tranquillity, HIM, X Japan, and Luna Sea

Passage 3:
Child labour
Child labour refers to the exploitation of children through any form of work that deprives them of their childhood, interferes with their ability to attend regular school, and is mentally, physically, socially and morally harmful  Such exploitation is prohibited by legislation worldwide, although these laws do not consider all work by children as child labour; exceptions include work by child artists, family duties, supervised training, and some forms of work undertaken by Amish children, as well as by indigenous children in the Americas Child labour has existed to varying extents throughout history  During the 19th and early 20th centuries, many children aged 5–14 from poorer families worked in Western nations and their colonies alike  These children mainly worked in agriculture, home-based assembly operations, factories, mining, and services such as news boys – some worked night shifts lasting 12 hours  With the rise of household income, availability of schools and passage of child labour laws, the incidence rates of child labour fell In the world's poorest countries, around one in four children are engaged in child labour, the highest number of whom (29 percent) live in sub-saharan Africa  In 2017, four African nations (Mali, Benin, Chad and Guinea-Bissau) witnessed over 50 percent of children aged 5–14 working  Worldwide agriculture is the largest employer of child labour  The vast majority of child labour is found in rural settings and informal urban economies; children are predominantly employed by their parents, rather than factories  Poverty and lack of schools are considered the primary cause of child labour Globally the incidence of child labour decreased from 25% to 10% between 1960 and 2003, according to the World Bank  Nevertheless, the total number of child labourers remains high, with UNICEF and ILO acknowledging an estimated 168 million children aged 5–17 worldwide were involved in child labour in 2013 

History
Child labour in preindustrial societies
Child labour forms an intrinsic part of pre-industrial economies  In pre-industrial societies, there is rarely a concept of childhood in the modern sense  Children often begin to actively participate in activities such as child rearing, hunting and farming as soon as they are competent  In many societies, children as young as 13 are seen as adults and engage in the same activities as adults The work of children was important in pre-industrial societies, as children needed to provide their labour for their survival and that of their group  Pre-industrial societies were characterised by low productivity and short life expectancy; preventing children from participating in productive work would be more harmful to their welfare and that of their group in the long run  In pre-industrial societies, there was little need for children to attend school  This is especially the case in non-literate societies  Most pre-industrial skill and knowledge were amenable to being passed down through direct mentoring or apprenticing by competent adults 

Industrial Revolution
With the onset of the Industrial Revolution in Britain in the late 18th century, there was a rapid increase in the industrial exploitation of labour, including child labour  Industrial cities such as Birmingham, Manchester, and Liverpool rapidly grew from small villages into large cities and improving child mortality rates  These cities drew in the population that was rapidly growing due to increased agricultural output  This process was replicated in other industrialising countries The Victorian era in particular became notorious for the conditions under which children were employed  Children as young as four were employed in production factories and mines working long hours in dangerous, often fatal, working conditions  In coal mines, children would crawl through tunnels too narrow and low for adults  Children also worked as errand boys, crossing sweepers, shoe blacks, or selling matches, flowers and other cheap goods  Some children undertook work as apprentices to respectable trades, such as building or as domestic servants (there were over 120,000 domestic servants in London in the mid-18th century)  Working hours were long: builders worked 64 hours a week in the summer and 52 hours in winter, while servants worked 80-hour weeks Child labour played an important role in the Industrial Revolution from its outset, often brought about by economic hardship  The children of the poor were expected to contribute to their family income  In 19th-century Great Britain, one-third of poor families were without a breadwinner, as a result of death or abandonment, obliging many children to work from a young age  In England and Scotland in 1788, two-thirds of the workers in 143 water-powered cotton mills were described as children  A high number of children also worked as prostitutes  The author Charles Dickens worked at the age of 12 in a blacking factory, with his family in debtor's prison Child wages were often low, the wages were as little as 10–20% of an adult male's wage  Karl Marx was an outspoken opponent of child labour, saying British industries "could but live by sucking blood, and children’s blood too", and that U S  capital was financed by the "capitalized blood of children"  Letitia Elizabeth Landon castigated child labour in her 1835 poem The Factory, portions of which she pointedly included in her 18th Birthday Tribute to Princess Victoria in 1837 
Throughout the second half of the 19th century, child labour began to decline in industrialised societies due to regulation and economic factors because of the Growth of trade unions  The regulation of child labour began from the earliest days of the Industrial Revolution  The first act to regulate child labour in Britain was passed in 1803  As early as 1802 and 1819 Factory Acts were passed to regulate the working hours of workhouse children in factories and cotton mills to 12 hours per day  These acts were largely ineffective and after radical agitation, by for example the "Short Time Committees" in 1831, a Royal Commission recommended in 1833 that children aged 11–18 should work a maximum of 12 hours per day, children aged 9–11 a maximum of eight hours, and children under the age of nine were no longer permitted to work  This act however only applied to the textile industry, and further agitation led to another act in 1847 limiting both adults and children to 10-hour working days  Lord Shaftesbury was an outspoken advocate of regulating child labour As technology improved and proliferated, there was a greater need for educated employees  This saw an increase in schooling, with the eventual introduction of compulsory schooling  Improved technology, automation and further legislation significantly reduced child labour particularly in western Europe and the U S 

Early 20th century
In the early 20th century, thousands of boys were employed in glass making industries  Glass making was a dangerous and tough job especially without the current technologies  The process of making glass includes intense heat to melt glass (3,133 °F (1,723 °C))  When the boys are at work, they are exposed to this heat  This could cause eye trouble, lung ailments, heat exhaustion, cuts, and burns  Since workers were paid by the piece, they had to work productively for hours without a break  Since furnaces had to be constantly burning, there were night shifts from 5:00 pm to 3:00 am  Many factory owners preferred boys under 16 years of age An estimated 1 7 million children under the age of fifteen were employed in American industry by 1900 In 1910, over 2 million children in the same age group were employed in the United States  This included children who rolled cigarettes, engaged in factory work, worked as bobbin doffers in textile mills, worked in coal mines and were employed in canneries  Lewis Hine's photographs of child labourers in the 1910s powerfully evoked the plight of working children in the American south  Hine took these photographs between 1908 and 1917 as the staff photographer for the National Child Labor Committee 

Household enterprises
Factories and mines were not the only places where child labour was prevalent in the early 20th century  Home-based manufacturing across the United States and Europe employed children as well  Governments and reformers argued that labour in factories must be regulated and the state had an obligation to provide welfare for poor  Legislation that followed had the effect of moving work out of factories into urban homes  Families and women, in particular, preferred it because it allowed them to generate income while taking care of household duties Home-based manufacturing operations were active year-round  Families willingly deployed their children in these income generating home enterprises  In many cases, men worked from home  In France, over 58% of garment workers operated out of their homes; in Germany, the number of full-time home operations nearly doubled between 1882 and 1907; and in the United States, millions of families operated out of home seven days a week, year round to produce garments, shoes, artificial flowers, feathers, match boxes, toys, umbrellas and other products  Children aged 5–14 worked alongside the parents  Home-based operations and child labour in Australia, Britain, Austria and other parts of the world was common  Rural areas similarly saw families deploying their children in agriculture  In 1946, Frieda S  Miller – then Director of the United States Department of Labor – told the International Labour Organization (ILO) that these home-based operations offered "low wages, long hours, child labour, unhealthy and insanitary working conditions" 

21st century
Child labour is still common in many parts of the world  Estimates for child labour vary  It ranges between 250 and 304 million, if children aged 5–17 involved in any economic activity are counted  If light occasional work is excluded, ILO estimates there were 153 million child labourers aged 5–14 worldwide in 2008  This is about 20 million less than ILO estimate for child labourers in 2004  Some 60 percent of the child labour was involved in agricultural activities such as farming, dairy, fisheries and forestry  Another 25% of child labourers were in service activities such as retail, hawking goods, restaurants, load and transfer of goods, storage, picking and recycling trash, polishing shoes, domestic help, and other services  The remaining 15% laboured in assembly and manufacturing in informal economy, home-based enterprises, factories, mines, packaging salt, operating machinery, and such operations  Two out of three child workers work alongside their parents, in unpaid family work situations  Some children work as guides for tourists, sometimes combined with bringing in business for shops and restaurants  Child labour predominantly occurs in the rural areas (70%) and informal urban sector (26%) 
Contrary to popular belief, most child labourers are employed by their parents rather than in manufacturing or formal economy  Children who work for pay or in-kind compensation are usually found in rural settings as opposed to urban centres  Less than 3% of child labour aged 5–14 across the world work outside their household, or away from their parents Child labour accounts for 22% of the workforce in Asia, 32% in Africa, 17% in Latin America, 1% in the US, Canada, Europe and other wealthy nations  The proportion of child labourers varies greatly among countries and even regions inside those countries  Africa has the highest percentage of children aged 5–17 employed as child labour, and a total of over 65 million  Asia, with its larger population, has the largest number of children employed as child labour at about 114 million  Latin America and the Caribbean region have lower overall population density, but at 14 million child labourers has high incidence rates too 

Accurate present day child labour information is difficult to obtain because of disagreements between data sources as to what constitutes child labour  In some countries, government policy contributes to this difficulty  For example, the overall extent of child labour in China is unclear due to the government categorizing child labour data as "highly secret"  China has enacted regulations to prevent child labour; still, the practice of child labour is reported to be a persistent problem within China, generally in agriculture and low-skill service sectors as well as small workshops and manufacturing enterprises In 2014, the U S  Department of Labor issued a List of Goods Produced by Child Labor or Forced Labor, where China was attributed 12 goods the majority of which were produced by both underage children and indentured labourers  The report listed electronics, garments, toys, and coal, among other goods 
The Maplecroft Child Labour Index 2012 survey reports that 76 countries pose extreme child labour complicity risks for companies operating worldwide  The ten highest risk countries in 2012, ranked in decreasing order, were: Myanmar, North Korea, Somalia, Sudan, DR Congo, Zimbabwe, Afghanistan, Burundi, Pakistan and Ethiopia  Of the major growth economies, Maplecroft ranked Philippines 25th riskiest, India 27th, China 36th, Vietnam 37th, Indonesia 46th, and Brazil 54th, all of them rated to involve extreme risks of child labour uncertainties, to corporations seeking to invest in developing world and import products from emerging markets 

Causes
The ILO suggests that poverty is the greatest single cause behind child labour  For impoverished households, income from a child's work is usually crucial for his or her own survival or for that of the household  Income from working children, even if small, may be between 25 and 40% of the household income  Other scholars such as Harsch on African child labour, and Edmonds and Pavcnik on global child labour have reached the same conclusion Lack of meaningful alternatives, such as affordable schools and quality education, according to the ILO, is another major factor driving children to harmful labour  Children work because they have nothing better to do  Many communities, particularly rural areas where between 60 and 70% of child labour is prevalent, do not possess adequate school facilities  Even when schools are sometimes available, they are too far away, difficult to reach, unaffordable or the quality of education is so poor that parents wonder if going to school is really worth it 

Cultural factors
In European history when child labour was common, as well as in contemporary child labour of modern world, certain cultural beliefs have rationalised child labour and thereby encouraged it  Some view that work is good for the character-building and skill development of children  In many cultures, particular where the informal economy and small household businesses thrive, the cultural tradition is that children follow in their parents' footsteps; child labour then is a means to learn and practice that trade from a very early age  Similarly, in many cultures the education of girls is less valued or girls are simply not expected to need formal schooling, and these girls pushed into child labour such as providing domestic services 

Macroeconomics
Biggeri and Mehrotra have studied the macroeconomic factors that encourage child labour  They focus their study on five Asian nations including India, Pakistan, Indonesia, Thailand and Philippines  They suggest that child labour is a serious problem in all five, but it is not a new problem  Macroeconomic causes encouraged widespread child labour across the world, over most of human history  They suggest that the causes for child labour include both the demand and the supply side  While poverty and unavailability of good schools explain the child labour supply side, they suggest that the growth of low-paying informal economy rather than higher paying formal economy is amongst the causes of the demand side  Other scholars too suggest that inflexible labour market, size of informal economy, inability of industries to scale up and lack of modern manufacturing technologies are major macroeconomic factors affecting demand and acceptability of child labour 

By country
Colonial empires
Systematic use of child labour was commonplace in the colonies of European powers between 1650 and 1950  In Africa, colonial administrators encouraged traditional kin-ordered modes of production, that is hiring a household for work not just the adults  Millions of children worked in colonial agricultural plantations, mines and domestic service industries  Sophisticated schemes were promulgated where children in these colonies between the ages of 5 and 14 were hired as an apprentice without pay in exchange for learning a craft  A system of Pauper Apprenticeship came into practice in the 19th century where the colonial master neither needed the native parents' nor child's approval to assign a child to labour, away from parents, at a distant farm owned by a different colonial master  Other schemes included 'earn-and-learn' programs where children would work and thereby learn  Britain for example passed a law, the so-called Masters and Servants Act of 1899, followed by Tax and Pass Law, to encourage child labour in colonies particularly in Africa  These laws offered the native people the legal ownership to some of the native land in exchange for making labour of wife and children available to colonial government's needs such as in farms and as picannins Beyond laws, new taxes were imposed on colonies  One of these taxes was the Head Tax in the British and French colonial empires  The tax was imposed on everyone older than 8 years, in some colonies  To pay these taxes and cover living expenses, children in colonial households had to work In southeast Asian colonies, such as Hong Kong, child labour such as the Mui Tsai (妹仔), was rationalised as a cultural tradition and ignored by British authorities  The Dutch East India Company officials rationalised their child labour abuses with, "it is a way to save these children from a worse fate " Christian mission schools in regions stretching from Zambia to Nigeria too required work from children, and in exchange provided religious education, not secular education  Elsewhere, the Canadian Dominion Statutes in form of so-called Breaches of Contract Act, stipulated jail terms for uncooperative child workers Proposals to regulate child labour began as early as 1786 

Africa
Children working at a young age has been a consistent theme throughout Africa  Many children began first working in the home to help their parents run the family farm  Children in Africa today are often forced into exploitative labour due to family debt and other financial factors, leading to ongoing poverty  Other types of domestic child labour include working in commercial plantations, begging, and other sales such as boot shining  In total, there is an estimated five million children who are currently working in the field of agriculture which steadily increases during the time of harvest  Along with 30% of children who are picking coffee, there are an estimated 25,000 school age children who work year round 

What industries children work in depends on whether they grew up in a rural area or an urban area  Children who were born in urban areas often found themselves working for street vendors, washing cars, helping in construction sites, weaving clothing, and sometimes even working as exotic dancers  While children who grew up in rural areas would work on farms doing physical labour, working with animals, and selling crops  Many children can also be found working in hazardous environments, with some using bare hands, stones and hammers to take apart CRT-based televisions and computer monitors  Of all the child workers, the most serious cases involved street children and trafficked children due to the physical and emotional abuse they endured by their employers  To address the issue of child labour, the United Nations Conventions on the Rights of the Child Act was implemented in 1959  Yet due to poverty, lack of education and ignorance, the legal actions were not/are not wholly enforced or accepted in Africa 

Other legal factors that have been implemented to end and reduce child labour includes the global response that came into force in 1979 by the declaration of the International Year of the Child  Along with the Human Rights Committee of the United Nations, these two declarations worked on many levels to eliminate child labour  Although many actions have been taken to end this epidemic, child labour in Africa is still an issue today due to the unclear definition of adolescence and how much time is needed for children to engage in activities that are crucial for their development  Another issue that often comes into play is the link between what constitutes as child labour within the household due to the cultural acceptance of children helping run the family business  In the end, there is a consistent challenge for the national government to strengthen its grip politically on child labour, and to increase education and awareness on the issue of children working below the legal age limit  With children playing an important role in the African economy, child labour still plays an important role for many in the 20th century 

Australia
From European settlement in 1788, child convicts were occasionally sent to Australia where they were made to work  Child labour was not as excessive in Australia as in Britain  With a low population, agricultural productivity was higher and families did not face starvation as in established industrialised countries  Australia also did not have significant industry until the later part of the 20th century, when child labour laws and compulsory schooling had developed under the influence of Britain  From the 1870s, child labour was restricted by compulsory schooling Child labour laws in Australia differ from state to state  Generally, children are allowed to work at any age, but restrictions exist for children under 15 years of age  These restrictions apply to work hours and the type of work that children can perform  In all states, children are obliged to attend school until a minimum leaving age, 15 years of age in all states except Tasmania and Queensland where the leaving age is 17 

Brazil
Child labour has been a consistent struggle for children in Brazil ever since Portuguese colonization in the region began in 1500  Work that many children took part in was not always visible, legal, or paid  Free or slave labour was a common occurrence for many youths and was a part of their everyday lives as they grew into adulthood  Yet due to there being no clear definition of how to classify what a child or youth is, there has been little historical documentation of child labour during the colonial period  Due to this lack of documentation, it is hard to determine just how many children were used for what kinds of work before the nineteenth century  The first documentation of child labour in Brazil occurred during the time of indigenous societies and slave labour where it was found that children were forcibly working on tasks that exceeded their emotional and physical limits  Armando Dias, for example, died in November 1913 whilst still very young, a victim of an electric shock when entering the textile industry where he worked  Boys and girls were victims of industrial accidents on a daily basis In Brazil, the minimum working age has been identified as fourteen due to constitutional amendments that passed in 1934, 1937, and 1946  Yet due to a change in the dictatorship by the military in the 1980s, the minimum age restriction was reduced to twelve but was reviewed due to reports of dangerous and hazardous working conditions in 1988  This led to the minimum age being raised once again to 14  Another set of restrictions was passed in 1998 that restricted the kinds of work youth could partake in, such as work that was considered hazardous like running construction equipment, or certain kinds of factory work  Although many steps were taken to reduce the risk and occurrence of child labour, there is still a high number of children and adolescents working under the age of fourteen in Brazil  It was not until recently in the 1980s that it was discovered that almost nine million children in Brazil were working illegally and not partaking in traditional childhood activities that help to develop important life experiences Brazilian census data (PNAD, 1999) indicate that 2 55 million 10- to 14-year-olds were illegally holding jobs  They were joined by 3 7 million 15- to 17-year-olds and about 375,000 5- to 9-year-olds  Due to the raised age restriction of 14, at least half of the recorded young workers had been employed illegally, which led to many not being protected by important labour laws  Although substantial time has passed since the time of regulated child labour, there are still many children working illegally in Brazil  Many children are used by drug cartels to sell and carry drugs, guns, and other illegal substances because of their perception of innocence  This type of work that youth are taking part in is very dangerous due to the physical and psychological implications that come with these jobs  Yet despite the hazards that come with working with drug dealers, there has been an increase in this area of employment throughout the country 

Britain
Many factors played a role in Britain's long-term economic growth, such as the industrial revolution in the late 1700s and the prominent presence of child labour during the industrial age  Children who worked at an early age were often not forced; but did so because they needed to help their family survive financially  Due to poor employment opportunities for many parents, sending their children to work on farms and in factories was a way to help feed and support the family  Child labour first started to occur in England when household businesses were turned into local labour markets that mass-produced the once homemade goods  Because children often helped produce the goods out of their homes, working in a factory to make those same goods was a simple change for many of these youths  Although there are many counts of children under the age of ten working for factories, the majority of children workers were between the ages of ten and fourteen 
Another factor that influenced child labour was the demographic changes that occurred in the eighteenth century  By the end of the eighteenth century, 20 percent of the population was made up of children between the ages of 5 and 14  Due to this substantial shift in available workers, and the development of the industrial revolution, children began to work earlier in life in companies outside of the home  Yet, even though there was an increase of child labour in factories such as cotton textiles, there were large numbers of children working in the field of agriculture and domestic production With such a high percentage of children working, the rising of illiteracy, and the lack of a formal education became a widespread issue for many children who worked to provide for their families  Due to this problematic trend, many parents developed a change of opinion when deciding whether or not to send their children to work  Other factors that lead to the decline of child labour included financial changes in the economy, changes in the development of technology, raised wages, and continuous regulations on factory legislation In 1933 Britain adopted legislation restricting the use of children under 14 in employment  The Children and Young Persons Act 1933, defined the term "child" as anyone of compulsory school age (age sixteen)  In general no child may be employed under the age of fifteen years, or fourteen years for light work 

Cambodia
Significant levels of child labour appear to be found in Cambodia  In 1998, ILO estimated that 24 1% of children in Cambodia aged between 10 and 14 were economically active  Many of these children work long hours and Cambodia Human Development Report 2000 reported that approximately 65,000 children between the ages of 5 and 13 worked 25 hours a week and did not attend school  There are also many initiative and policies put in place to decrease the prevalence of child labour such as the United States generalized system of preferences, the U S -Cambodia textile agreement, ILO Garment Sector Working Conditions Improvement Project, and ChildWise Tourism 

Ecuador
An Ecuadorean study published in 2006 found child labour to be one of the main environmental problems affecting children's health  It reported that over 800,000 children are working in Ecuador, where they are exposed to heavy metals and toxic chemicals and are subject to mental and physical stress and the insecurity caused by being at risk of work-related accidents  Minors performing agricultural work along with their parents help apply pesticides without wearing protective equipment 

India
In 2015, the country of India is home to the largest number of children who are working illegally in various industrial industries  Agriculture in India is the largest sector where many children work at early ages to help support their family  Many of these children are forced to work at young ages due to many family factors such as unemployment, large families, poverty, and lack of parental education  This is often the major cause of the high rate of child labour in India On 23 June 1757, the English East India Company defeated Siraj-ud-Daula, the Nawab of Bengal, in the Battle of Plassey  The British thus became masters of east India (Bengal, Bihar, Orissa) – a prosperous region with a flourishing agriculture, industry and trade  This led to many children being forced into labour due to the increasing need of cheap labour to produce large numbers of goods  Many multinationals often employed children because that they can be recruited for less pay, and have more endurance to utilise in factory environments  Another reason many Indian children were hired was because they lack knowledge of their basic rights, they did not cause trouble or complain, and they were often more trustworthy  The innocence that comes with childhood was utilised to make a profit by many and was encouraged by the need for family income 

A variety of Indian social scientists as well as the non-governmental organisations (NGOs) have done extensive research on the numeric figures of child labour found in India and determined that India contributes to one-third of Asia's child labour and one-fourth of the world's child labour  Due to many children being illegally employed, the Indian government began to take extensive actions to reduce the number of children working, and to focus on the importance of facilitating the proper growth and development of children  International influences help to encourage legal actions to be taken in India, such as the Geneva Declaration of the Right of Children Act was passed in 1924  This act was followed by The Universal Declaration of Human Rights in 1948 to which incorporated the basic human rights and needs of children for proper progression and growth in their younger years  These international acts encouraged major changes to the workforce in India which occurred in 1986 when the Child Labour (Prohibition and Regulation) Act was put into place  This act prohibited hiring children younger than the age of 14, and from working in hazardous conditions Due to the increase of regulations and legal restrictions on child labour, there has been a 64 percent decline in child labour from 1993 to 2005  Although this is a great decrease in the country of India, there is still high numbers of children working in the rural areas of India  With 85 percent of the child labour occurring in rural areas, and 15 percent occurring in urban areas, there are still substantial areas of concern in the country of India India has legislation since 1986 which allows work by children in non-hazardous industry  In 2013, the Punjab and Haryana High Court gave a landmark order that directed that there shall be a total ban on the employment of children up to the age of 14 years, be it hazardous or non-hazardous industries  However, the Court ruled that a child can work with his or her family in family based trades/occupations, for the purpose of learning a new trade/craftsmanship or vocation 

Iran
In Isfahan province, the Iranian Department of State Welfare (behzisti) keeps a database of the scanned retina irises of a number of working street kids, and have put "child friendly" measures in place to support them, reduce the social harm from their presence, and improve their quality of life Only Tehran as of June 2023 has seventy thousand working children they also collect recycles 

Ireland
In post-colonial Ireland, the rate of child exploitation was extremely high as children were used as farm labourers once they were able to walk, these children were never paid for the labour that they carried out on the family farm  Children were wanted and desired in Ireland for the use of their labour on the family farm  Irish parents felt that it was the children's duty to carry out chores on the family farm 

Japan
Though banned in modern Japan, shonenko (child labourers) were a feature of the Imperial era until its end in 1945  During World War II labour recruiting efforts targeted youths from Taiwan (Formosa), then a Japanese territory, with promises of educational opportunity  Though the target of 25,000 recruits was never reached, over 8,400 Taiwanese youths aged 12 to 14 relocated to Japan to help manufacture the Mitsubishi J2M Raiden aircraft 

Pakistan
The Netherlands
Child labour existed in the Netherlands up to and through the Industrial Revolution  Laws governing child labour in factories were first passed in 1874, but child labour on farms continued to be the norm up until the 20th century 

Soviet Union and successor states
Although formally banned since 1922, child labour was widespread in the Soviet Union, mostly in the form of mandatory, unpaid work by schoolchildren on Saturdays and holidays  The students were used as a cheap, unqualified workforce on kolhoz (collective farms) as well as in industry and forestry  The practice was formally called "work education" From the 1950s on, the students were also used for unpaid work at schools, where they cleaned and performed repairs  This practice has continued in the Russian Federation, where up to 21 days of the summer holidays is sometimes set aside for school works  By law, this is only allowed as part of specialised occupational training and with the students' and parents' permission, but those provisions are widely ignored  In 2012 there was an accident near the city of Nalchik where a car killed several pupils cleaning up a highway shoulder during their "holiday work", as well as their teacher, who was supervising them Out of former Soviet Union republics Uzbekistan continued and expanded the program of child labour on industrial scale to increase profits on the main source of Islam Karimov's income, cotton harvesting  In September, when school normally starts, the classes are suspended and children are sent to cotton fields for work, where they are assigned daily quotas of 20 to 60 kg of raw cotton they have to collect  This process is repeated in spring, when collected cotton needs to be hoed and weeded  In 2006 it is estimated that 2 7 million children were forced to work this way 

Switzerland
As in many other countries, child labour in Switzerland affected among the so-called Kaminfegerkinder ("chimney sweep children") and children working p e  in spinning mills, factories and in agriculture in 19th-century Switzerland, but also to the 1960s so-called Verdingkinder (literally: "contract children" or "indentured child laborers") were children who were taken from their parents, often due to poverty or moral reasons – usually mothers being unmarried, very poor citizens, of Gypsy–Yeniche origin, so-called Kinder der Landstrasse, etc  – and sent to live with new families, often poor farmers who needed cheap labour There were even Verdingkinder auctions where children were handed over to the farmer asking the least money from the authorities, thus securing cheap labour for his farm and relieving the authority from the financial burden of looking after the children  In the 1930s 20% of all agricultural labourers in the Canton of Bern were children below the age of 15  Swiss municipality guardianship authorities acted so, commonly tolerated by federal authorities, to the 1960s, not all of them of course, but usually communities affected of low taxes in some Swiss cantons Swiss historian Marco Leuenberger investigated, that in 1930 there were some 35,000 indentured children, and between 1920 and 1970 more than 100,000 are believed to have been placed with families or homes  10,000 Verdingkinder are still alive  Therefore, the so-called Wiedergutmachungsinitiative was started in April 2014  In April 2014 the collection of targeted at least authenticated 100,000 signatures of Swiss citizens has started, and still have to be collected to October 2015 

United States
Child labour laws in the United States are found at the federal and state levels  The most sweeping federal law that restricts the employment and abuse of child workers is the Fair Labor Standards Act (FLSA)  Child labour provisions under FLSA are designed to protect the educational opportunities of youth and prohibit their employment in jobs that are detrimental to their health and safety  FLSA restricts the hours that youth under 16 years of age can work and lists hazardous occupations too dangerous for young workers to perform 
Under the FLSA, for non-agricultural jobs, children under 14 may not be employed, children between 14 and 16 may be employed in allowed occupations during limited hours, and children between 16 and 17 may be employed for unlimited hours in non-hazardous occupations  A number of exceptions to these rules exist, such as for employment by parents, newspaper delivery, and child actors  The regulations for agricultural employment are generally less strict 
States have varying laws covering youth employment  Each state has minimum requirements such as, earliest age a child may begin working, number of hours a child is allowed to be working during the day, number of hours a child is allowed to be worked during the week  The United States Department of Labor lists the minimum requirements for agricultural work in each state  Where state law differs from federal law on child labour, the law with the more rigorous standard applies Individual states have a wide range of restrictions on labor by minors, often requiring work permits for minors who are still enrolled in high school, limiting the times and hours that minors can work by age and imposing additional safety regulations 

Child labour laws and initiatives
Almost every country in the world has laws relating to and aimed at preventing child labour  International Labour Organization has helped set international law, which most countries have signed on and ratified  According to ILO minimum age convention (C138) of 1973, child labour refers to any work performed by children under the age of 12, non-light work done by children aged 12–14, and hazardous work done by children aged 15–17  Light work was defined, under this convention, as any work that does not harm a child's health and development, and that does not interfere with his or her attendance at school  This convention has been ratified by 171 countries 
The United Nations adopted the Convention on the Rights of the Child in 1990, which was subsequently ratified by 193 countries  Article 32 of the convention addressed child labour, as follows:   Parties recognise the right of the child to be protected from economic exploitation and from performing any work that is likely to be hazardous or to interfere with the child's education, or to be harmful to the child's health or physical, mental, spiritual, moral or social development 
Under Article 1 of the 1990 Convention, a child is defined as "every human being below the age of eighteen years unless, under the law applicable to the child, a majority is attained earlier " Article 28 of this Convention requires States to, "make primary education compulsory and available free to all "195 countries are party to the convention; only two nations have not ratified the treaty, Somalia and the United States In 1999, ILO helped lead the Worst Forms Convention 182 (C182), which has so far been signed upon and domestically ratified by 151 countries including the United States  This international law prohibits worst forms of child labour, defined as all forms of slavery and slavery-like practices, such as child trafficking, debt bondage, and forced labour, including forced recruitment of children into armed conflict  The law also prohibits the use of a child for prostitution or the production of pornography, child labour in illicit activities such as drug production and trafficking; and in hazardous work  Both the Worst Forms Convention (C182) and the Minimum Age Convention (C138) are examples of international labour standards implemented through the ILO that deal with child labour 
In addition to setting the international law, the United Nations initiated International Program on the Elimination of Child Labour (IPEC) in 1992  This initiative aims to progressively eliminate child labour through strengthening national capacities to address some of the causes of child labour  Amongst the key initiative is the so-called time-bounded programme countries, where child labour is most prevalent and schooling opportunities lacking  The initiative seeks to achieve amongst other things, universal primary school availability  The IPEC has expanded to at least the following target countries: Bangladesh, Brazil, China, Egypt, India, Indonesia, Mexico, Nigeria, Pakistan, Democratic Republic of Congo, El Salvador, Nepal, Tanzania, Dominican Republic, Costa Rica, Philippines, Senegal, South Africa and Turkey 
Targeted child labour campaigns were initiated by the International Programme on the Elimination of Child Labour (IPEC) in order to advocate for prevention and elimination of all forms of child labour  The global Music against Child Labour Initiative was launched in 2013 in order to involve socially excluded children in structured musical activity and education in efforts to help protect them from child labour 

Exceptions granted
In 2004, the United States passed an amendment to the Fair Labor Standards Act of 1938  The amendment allows certain children aged 14–18 to work in or outside a business where machinery is used to process wood  The law aims to respect the religious and cultural needs of the Amish community of the United States  The Amish believe that one effective way to educate children is on the job  The new law allows Amish children the ability to work with their families, once they are past eighth grade in school 
Similarly, in 1996, member countries of the European Union, per Directive 94/33/EC, agreed to a number of exceptions for young people in its child labour laws  Under these rules, children of various ages may work in cultural, artistic, sporting or advertising activities if authorised by the competent authority  Children above the age of 13 may perform light work for a limited number of hours per week in other economic activities as defined at the discretion of each country  Additionally, the European law exception allows children aged 14 years or over to work as part of a work/training scheme  The EU Directive clarified that these exceptions do not allow child labour where the children may experience harmful exposure to dangerous substances  Nonetheless, many children under the age of 13 do work, even in the most developed countries of the EU  For instance, a recent study showed over a third of Dutch twelve-year-old kids had a job, the most common being babysitting 

More laws vs  more freedom
Very often, however, these state laws were not enforced    Federal legislation was passed in 1916 and again in 1919, but both laws were declared unconstitutional by the Supreme Court  Although the number of child workers declined dramatically during the 1920s and 1930s, it was not until the Fair Labor Standards Act in 1938 that federal regulation of child labor finally became a reality 
Scholars disagree on the best legal course forward to address child labour  Some suggest the need for laws that place a blanket ban on any work by children less than 18 years old  Others suggest the current international laws are enough, and the need for more engaging approach to achieve the ultimate goals Some scholars suggest any labour by children aged 18 years or less is wrong since this encourages illiteracy, inhumane work and lower investment in human capital  These activists claim that child labor also leads to poor labour standards for adults, depresses the wages of adults in developing countries as well as the developed countries, and dooms the third world economies to low-skill jobs only capable of producing poor quality cheap exports  More children that work in poor countries, the fewer and worse-paid are the jobs for adults in these countries  In other words, there are moral and economic reasons that justify a blanket ban on labour from children aged 18 years or less, everywhere in the world 

Other scholars suggest that these arguments are flawed, ignores history and more laws will do more harm than good  According to them, child labour is merely the symptom of a greater disease named poverty  If laws ban all lawful work that enables the poor to survive, informal economy, illicit operations and underground businesses will thrive  These will increase abuse of the children  In poor countries with very high incidence rates of child labour - such as Ethiopia, Chad, Niger and Nepal - schools are not available, and the few schools that exist offer poor quality education or are unaffordable  The alternatives for children who currently work, claim these studies, are worse: grinding subsistence farming, militia or prostitution  Child labour is not a choice, it is a necessity, the only option for survival  It is currently the least undesirable of a set of very bad choices 

These scholars suggest, from their studies of economic and social data, that early 20th-century child labour in Europe and the United States ended in large part as a result of the economic development of the formal regulated economy, technology development and general prosperity  Child labour laws and ILO conventions came later  Edmonds suggests, even in contemporary times, the incidence of child labour in Vietnam has rapidly reduced following economic reforms and GDP growth  These scholars suggest economic engagement, emphasis on opening quality schools rather than more laws and expanding economically relevant skill development opportunities in the third world  International legal actions, such as trade sanctions increase child labour The Incredible Bread Machine, a book published by "World Research, Inc " in 1974, stated:

Child labour was a particular target of early reformers  William Cooke Tatlor wrote at the time about these reformers who, witnessing children at work in the factories, thought to themselves: 'How much more delightful would have been the gambol of the free limbs on the hillside; the sight of the green mead with its spangles of buttercups and daisies; the song of the bird and the humming bee   '
But for many of these children the factory system meant quite literally the only chance for survival  Today we overlook the fact that death from starvation and exposure was a common fate before the Industrial Revolution, for the pre-capitalist economy was barely able to support the population  Yes, children were working  Formerly they would have starved  It was only as goods were produced in greater abundance at a lower cost that men could support their families without sending their children to work  It was not the reformer or the politician that ended the grim necessity for child labour; it was capitalism 

Incidents
Cocoa production
In 1998, UNICEF reported that Ivory Coast farmers used enslaved children – many from surrounding countries  In late 2000 a BBC documentary reported the use of enslaved children in the production of cocoa – the main ingredient in chocolate – in West Africa  Other media followed by reporting widespread child slavery and child trafficking in the production of cocoa  In 2001, the US State Department estimated there were 15,000 child slaves cocoa, cotton and coffee farms in the Ivory Coast, and the Chocolate Manufacturers Association acknowledged that child slavery is used in the cocoa harvest Malian migrants have long worked on cocoa farms in the Ivory Coast, but in 2000 cocoa prices had dropped to a 10-year low and some farmers stopped paying their employees  The Malian counsel had to rescue some boys who had not been paid for five years and who were beaten if they tried to run away  Malian officials believed that 15,000 children, some as young as 11 years old, were working in the Ivory Coast in 2001  These children were often from poor families or the slums and were sold to work in other countries  Parents were told the children would find work and send money home, but once the children left home, they often worked in conditions resembling slavery  In other cases, children begging for food were lured from bus stations and sold as slaves  In 2002, the Ivory Coast had 12,000 children with no relatives nearby, which suggested they were trafficked, likely from neighboring Mali, Burkina Faso and Togo The cocoa industry was accused of profiting from child slavery and trafficking  The European Cocoa Association dismissed these accusations as "false and excessive" and the industry said the reports were not representative of all areas  Later the industry acknowledged the working conditions for children were unsatisfactory and children's rights were sometimes violated and acknowledged the claims could not be ignored  In a BBC interview, the ambassador for Ivory Coast to the United Kingdom called these reports of widespread use of slave child labour by 700,000 cocoa farmers as absurd and inaccurate In 2001, a voluntary agreement called the Harkin-Engel Protocol, was accepted by the international cocoa and chocolate industry to eliminate the worst forms of child labour, as defined by ILO's Convention 182, in West Africa  This agreement created a foundation named International Cocoa Initiative in 2002  The foundation claims it has, as of 2011, active programs in 290 cocoa growing communities in Côte d'Ivoire and Ghana, reaching a total population of 689,000 people to help eliminate the worst forms of child labour in cocoa industry  Other organisations claim progress has been made, but the protocol's 2005 deadlines have not yet been met 

Mining in Africa
In 2008, Bloomberg claimed child labour in copper and cobalt mines that supplied Chinese companies in Congo  The children are creuseurs, that is they dig the ore by hand, carry sacks of ores on their backs, and these are then purchased by these companies  Over 60 of Katanga's 75 processing plants are owned by Chinese companies and 90 percent of the region's minerals go to China  An African NGO report claimed 80,000 child labourers under the age of 15, or about 40% of all miners, were supplying ore to Chinese companies in this African region Amnesty International alleged in 2016 that some cobalt sold by Congo Dongfang Mining was produced by child labour, and that it was being used in lithium-ion batteries powering electric cars and mobile devices worldwide BBC, in 2012, accused Glencore of using child labour in its mining and smelting operations of Africa  Glencore denied it used child labour, and said it has strict policy of not using child labour  The company claimed it has a strict policy whereby all copper was mined correctly, placed in bags with numbered seals and then sent to the smelter  Glencore mentioned being aware of child miners who were part of a group of artisanal miners who had without authorisation raided the concession awarded to the company since 2010; Glencore has been pleading with the government to remove the artisanal miners from the concession Small-scale artisanal mining of gold is another source of dangerous child labour in poor rural areas in certain parts of the world  This form of mining uses labour-intensive and low-tech methods  It is informal sector of the economy  Human Rights Watch group estimates that about 12 percent of global gold production comes from artisanal mines  In west Africa, in countries such as Mali – the third largest exporter of gold in Africa – between 20,000 and 40,000 children work in artisanal mining  Locally known as orpaillage, children as young as six years old work with their families  These children and families suffer chronic exposure to toxic chemicals including mercury, and do hazardous work such as digging shafts and working underground, pulling up, carrying and crushing the ore  The poor work practices harm the long-term health of children, as well as release hundreds of tons of mercury every year into local rivers, ground water and lakes  Gold is important to the economy of Mali and Ghana  For Mali, it is the second largest earner of its export revenue  For many poor families with children, it is the primary and sometimes the only source of income 

Meatpacking
In early August 2008, Iowa Labour Commissioner David Neil announced that his department had found that Agriprocessors, a kosher meatpacking company in Postville which had recently been raided by Immigration and Customs Enforcement, had employed 57 minors, some as young as 14, in violation of state law prohibiting anyone under 18 from working in a meatpacking plant  Neil announced that he was turning the case over to the state Attorney General for prosecution, claiming that his department's inquiry had discovered "egregious violations of virtually every aspect of Iowa's child labour laws " Agriprocessors claimed that it was at a loss to understand the allegations  Agriprocessors' CEO went to trial on these charges in state court on 4 May 2010  After a five-week trial he was found not guilty of all 57 charges of child labour violations by the Black Hawk County District Court jury in Waterloo, Iowa, on 7 June 2010 

GAP
A 2007 report claimed some GAP products had been produced by child labourers  GAP acknowledged the problem and announced it is pulling the products from its shelves  The report found that GAP had rigorous social audit systems since 2004 to eliminate child labour in its supply chain  However, the report concluded that the system was being abused by unscrupulous subcontractors 
GAP's policy, the report claimed, is that if it discovers child labour was used by its supplier in its branded clothes, the contractor must remove the child from the workplace, provide them with access to schooling and a wage, and guarantee the opportunity of work on reaching a legal working age 
In 2007, The New York Times reported that GAP, after the child labour discovery, created a $200,000 grant to improve working conditions in the supplier community  GAP created strong relationships with developing countries to help prevent child labor and find solutions; GAP would conduct interviews and reach out to their 100,000 employees worldwide to get insight into how they feel about GAP's work environments  This survey concluded with a 68 percent response rate, and 77 percent of respondents considered GAP a great environment to work in  GAP's corporate responsibility has allowed them to strengthen their stockholder relationships and be known as one of the fast fashion industry's best companies, with a great image representing a responsible firm 

H&M and Zara
In December 2009, campaigners in the UK called on two leading high street retailers to stop selling clothes made with cotton which may have been picked by children  Anti-Slavery International and the Environmental Justice Foundation (EJF) accused H&M and Zara of using cotton suppliers in Bangladesh  It is also suspected that many of their raw materials originates from Uzbekistan, where children aged 10 are forced to work in the fields  The activists were calling to ban the use of Uzbek cotton and implement a "track and trace" systems to guarantee an ethical responsible source of the material 
H&M said it "does not accept" child labour and "seeks to avoid" using Uzbek cotton, but admitted it did "not have any reliable methods" to ensure Uzbek cotton did not end up in any of its products  Inditex, the owner of Zara, said its code of conduct banned child labour 

Silk weaving
A 2003 Human Rights Watch report claimed children as young as five years old were employed and worked for up to 12 hours a day and six to seven days a week in the silk industry  These children, HRW claimed, were bonded child labour in India, easy to find in Karnataka, Uttar Pradesh, and Tamil Nadu In 2010, a German news investigative report claimed that non-governmental organisations (NGOs) had found up to 10,000 children working in the 1,000 silk factories in 1998  In other locations, thousands of bonded child labourers were present in 1994  After UNICEF and NGOs got involved, the child labour figure dropped drastically after 2005, with the total estimated to be fewer than a thousand child labourers  The report claims the released children were back in school 

Primark
In 2008, the BBC reported that the company Primark was using child labour in the manufacture of clothing  In particular, a £4 hand-embroidered shirt was the starting point of a documentary produced by BBC's Panorama programme  The programme asks consumers to ask themselves, "Why am I only paying £4 for a hand embroidered top? This item looks handmade  Who made it for such little cost?", in addition to exposing the violent side of the child labour industry in countries where child exploitation is prevalent 
As a result of the BBC report, Royal Television Society awarded it a prize, and Primark took immediate action and fired three Indian suppliers in 2008 Primark continued to investigate the allegations for three years, concluding that BBC report was a fake  In 2011, following an investigation by the BBC Trust's Editorial Standards Committee, the BBC announced, "Having carefully scrutinised all of the relevant evidence, the committee concluded that, on the balance of probabilities, it was more likely than not that the Bangalore footage was not authentic " BBC subsequently apologised for faking footage, and returned the television award for investigative reporting 

Eliminating child labour
Concerns have often been raised over the buying public's moral complicity in purchasing products assembled or otherwise manufactured in developing countries with child labour  However, others have raised concerns that boycotting products manufactured through child labour may force these children to turn to more dangerous or strenuous professions, such as prostitution or agriculture  For example, a UNICEF study found that after the Child Labor Deterrence Act was introduced in the US, an estimated 50,000 children were dismissed from their garment industry jobs in Bangladesh, leaving many to resort to jobs such as "stone-crushing, street hustling, and prostitution", jobs that are "more hazardous and exploitative than garment production"  The study suggests that boycotts are "blunt instruments with long-term consequences, that can actually harm rather than help the children involved "According to Milton Friedman, before the Industrial Revolution virtually all children worked in agriculture  During the Industrial Revolution many of these children moved from farm work to factory work  Over time, as real wages rose, parents became able to afford to send their children to school instead of work and as a result child labour declined, both before and after legislation British historian and socialist E  P  Thompson in The Making of the English Working Class draws a qualitative distinction between child domestic work and participation in the wider (waged) labour market  Further, the usefulness of the experience of the industrial revolution in making predictions about current trends has been disputed  Social historian Hugh Cunningham, author of Children and Childhood in Western Society Since 1500, notes that:

Fifty years ago it might have been assumed that, just as child labour had declined in the developed world in the late nineteenth and early twentieth centuries, so it would also, in a trickle-down fashion, in the rest of the world  Its failure to do that, and its re-emergence in the developed world, raise questions about its role in any economy, whether national or global According to Thomas DeGregori, an economics professor at the University of Houston, in an article published by the Cato Institute, a libertarian think-tank operating in Washington D C , "it is clear that technological and economic change are vital ingredients in getting children out of the workplace and into schools  Then they can grow to become productive adults and live longer, healthier lives  However, in poor countries like Bangladesh, working children are essential for survival in many families, as they were in our own heritage until the late 19th century  So, while the struggle to end child labour is necessary, getting there often requires taking different routes—and, sadly, there are many political obstacles The International Programme on the Elimination of Child Labour (IPEC), founded in 1992, aims to eliminate child labour  It operates in 88 countries and is the largest program of its kind in the world  IPEC works with international and government agencies, NGOs, the media, and children and their families to end child labour and provide children with education and assistance From 2008 to 2013, the ILO operated a program through IPEC entitled "Combating Abusive Child Labour (CACL-II)"  The project, funded by the European Union, contributed to the Government of Pakistan by providing alternative opportunities for vocational training and education to children withdrawn from the worst forms of child labour Periodically, governments, employers' and workers' organisations have met in global conference to assess progress and remaining obstacles and to agree measures to eliminate the worst forms of child labour by 2016: first in Oslo (1997), followed by: The Hague (2010); Brasilia, 8–10 October 2013; Buenos Aires, 14–16 November 2017; and most recently Durban, South Africa, 15–20 May 2022 Between 2000 and 2012, progress was made against child labor but the elimination of its worst forms was not accomplished 
Under the Sustainable Development Goals (SDGs) of the 2030 Agenda, UN Member States, employers' and workers' organizations, and civil society organizations are required to work together to eliminate child labor by 2025, forced labor, modern slavery and human trafficking by 2030  Thus, the ILO established Alliance 8 7 as a global partnership In January 2021, the ILO published the Child Labour Global Estimates 2020 in collaboration with UNICEF  According to the report child labor decreased by 38% from 246 million in 2000 million to 152 million in 2016  Due to COVID-19 pandemic the number of children in child labor increased by 9 million 

Statistics
Potential positives
The term child labour can be misleading when it confuses harmful work with employment that may be beneficial to children  It can also ignore harmful work outside employment and any benefits children normally derive from their work  Domestic work is an example: all families but the rich must work at cleaning, cooking, caring, and more to maintain their homes  In most families in the world, this process extends to productive activities, especially herding and various types of agriculture, and to a variety of small family businesses  Where trading is a significant feature of social life, children can start trading in small items at an early age, often in the company of family members or of peers Work is undertaken from an early age by vast numbers of children in the world and may have a natural place in growing up 
Work can contribute to the well-being of children in a variety of ways; children often choose to work to improve their lives, both in the short- and long-term  At the material level, children's work often contributes to producing food or earning income that benefits themselves and their families; and such income is especially important when the families are poor  Work can provide an escape from debilitating poverty, sometimes by allowing a young person to move away from an impoverished environment  Young people often enjoy their work, especially paid work, or when work involves the company of peers  Even when work is intensive and enforced, children often find ways to combine their work with play While full-time work hinders schooling, empirical evidence is varied on the relationship between part-time work and school  Sometimes even part-time work may hinder school attendance or performance  On the other hand, many poor children work for resources to attend school  Children who are not doing well at school sometimes seek more satisfactory experience in work  Good relations with a supervisor at work can provide relief from tensions that children feel at school and home  In the modern world, school education has become so central to society that schoolwork has become the dominant work for most children, often replacing participation in productive work  If school curricula or quality do not provide children with appropriate skills for available jobs or if children do nor have the aptitude for schoolwork, school may impede the learning of skills, such as agriculture, which will become necessary for future livelihood 

In media
Letitia Elizabeth Landon addresses this issue in scathing terms in her poem  The Factory  (1835)  'Tis an accursed thing!—she writes 
Oliver Twist, a novel by Charles Dickens that was later adapted into films and into a theater production 
"The Little Match Girl", a short story by Hans Christian Andersen that was later adapted into films and other media

Notes
Passage 4:
Sigrid Sture
Sigrid Svantesdotter Sture (13 December 1538, Mörkö, Södermanland – 16 March 1613), was a Swedish noble, Governor (häradshövding) of Stranda Hundred from 1577 to 1613 
She was the daughter of Svante Stensson Sture and Märta ("king Martha") Erikdotter Leijonhufvud, thereby the niece of queen Margaret Leijonhufvud and the granddaughter of regent Christina Gyllenstierna  She married Ture Pedersson Bielke and became the mother of Svante Turesson Bielke  After the death of her husband in 1577, she succeeded him as royal governor of Stranda hundred  This was an unusual position for a person of her gender in 16th century Sweden, and one she kept until her death over 30 years later  She was, however, not allowed to rule formally, but was forced to appoint male proxies to officially rule in her place

Three for Shepp
Three for Shepp is an album by American saxophonist Marion Brown featuring performances recorded in 1966 for the Impulse! label 

Reception
The Allmusic review by Thom Jurek awarded the album 4½ stars, stating: "Marion Brown's Three for Shepp is the image-in-the-mirror companion to Archie Shepp's Four for Trane recorded the year before  The program is equally divided between Brown's originals, which occupy the first half of the album, and Shepp tunes that take up the latter half  What is immediately striking is how similar in tone, color, and texture the two men were when it came to composition  Brown arms himself here with crack bands for these recordings    This is a classic Impulse! recording of the period by an overlooked master "The authors of the Penguin Jazz Guide wrote: "Brown's Impulse! records are routinely overlooked    In the wake of this, his first successful record, Brown took to the road, playing tirelessly but curbing his studio activities  Impulse! had already released Shepp's Four For Trane  This was explicitly intended as a companion project and its arresting opening    establishes it as one of the most inventive in the label's distinguished catalogue    Brief as it is at just 35 minutes, Three For Shepp is so densely packed with musical information that it takes many, many listens to deconstruct: a living lesson in musical history, a passionate manifesto for the future "A reviewer at SoundOhm included the album in the "Best of 2019" playlist, and stated: "Three For Shepp balances fiery energy and delicate precision    Even this early in his career, Brown stood apart from his peers in "the new thing " His solos were as gentle as they were furious  Informed by the African American folk traditions of his native Georgia and an enthusiastic embrace of the avant-garde, his music would confront and challenge society  As Brown says in the original liner notes, 'The music is definitely a part of what's going on in the black revolution in America '  Three For Shepp still sounds crucial today (over 50 years later) and remains a vital statement of jazz's past, present and future "

Context 3: Passage 1:
James Chadwick
Sir James Chadwick,  (20 October 1891 – 24 July 1974) was a British physicist who was awarded the 1935 Nobel Prize in Physics for his discovery of the neutron in 1932  In 1941, he wrote the final draft of the MAUD Report, which inspired the U S  government to begin serious atom bomb research efforts  He was the head of the British team that worked on the Manhattan Project during World War II  He was knighted in Britain in 1945 for his achievements in physics 
Chadwick graduated from the Victoria University of Manchester in 1911, where he studied under Ernest Rutherford (known as the "father of nuclear physics")  At Manchester, he continued to study under Rutherford until he was awarded his MSc in 1913  The same year, Chadwick was awarded an 1851 Research Fellowship from the Royal Commission for the Exhibition of 1851  He elected to study beta radiation under Hans Geiger in Berlin  Using Geiger's recently developed Geiger counter, Chadwick was able to demonstrate that beta radiation produced a continuous spectrum, and not discrete lines as had been thought  Still in Germany when World War I broke out in Europe, he spent the next four years in the Ruhleben internment camp 
After the war, Chadwick followed Rutherford to the Cavendish Laboratory at the University of Cambridge, where Chadwick earned his Doctor of Philosophy degree under Rutherford's supervision from Gonville and Caius College, Cambridge, in June 1921  He was Rutherford's assistant director of research at the Cavendish Laboratory for over a decade at a time when it was one of the world's foremost centres for the study of physics, attracting students like John Cockcroft, Norman Feather, and Mark Oliphant  Chadwick followed his discovery of the neutron by measuring its mass  He anticipated that neutrons would become a major weapon in the fight against cancer  Chadwick left the Cavendish Laboratory in 1935 to become a professor of physics at the University of Liverpool, where he overhauled an antiquated laboratory and, by installing a cyclotron, made it an important centre for the study of nuclear physics 
During the Second World War, Chadwick carried out research as part of the Tube Alloys project to build an atom bomb, while his Manchester lab and environs were harassed by Luftwaffe bombing  When the Quebec Agreement merged his project with the American Manhattan Project, he became part of the British Mission, and worked at the Los Alamos Laboratory and in Washington, D C  He surprised everyone by earning the almost-complete trust of project director Leslie R  Groves, Jr  For his efforts, Chadwick received a knighthood in the New Year Honours on 1 January 1945  In July 1945, he viewed the Trinity nuclear test  After this, he served as the British scientific advisor to the United Nations Atomic Energy Commission  Uncomfortable with the trend toward Big Science, he became the Master of Gonville and Caius College in 1948  He retired in 1959 

Education and early life
James Chadwick was born in Bollington, Cheshire, on 20 October 1891, the first child of John Joseph Chadwick, a cotton spinner, and Anne Mary Knowles, a domestic servant  He was named James after his paternal grandfather  In 1895, his parents moved to Manchester, leaving him in the care of his maternal grandparents  He went to Bollington Cross Primary School, and was offered a scholarship to Manchester Grammar School, which his family had to turn down as they could not afford the small fees that still had to be paid  Instead he attended the Central Grammar School for Boys in Manchester, rejoining his parents there  He now had two younger brothers, Harry and Hubert; a sister had died in infancy  At the age of 16, he sat two examinations for university scholarships, and won both of them Chadwick chose to attend Victoria University of Manchester, which he entered in 1908  He meant to study mathematics, but enrolled in physics by mistake  Like most students, he lived at home, walking the 4 miles (6 4 km) to the university and back each day  At the end of his first year, he was awarded a Heginbottom Scholarship to study physics  The physics department was headed by Ernest Rutherford, who assigned research projects to final-year students, and he instructed Chadwick to devise a means of comparing the amount of radioactive energy of two different sources  The idea was that they could be measured in terms of the activity of 1 gram (0 035 oz) of radium, a unit of measurement which would become known as the curie  Rutherford's suggested approach was unworkable—something Chadwick knew but was afraid to tell Rutherford—so Chadwick pressed on, and eventually devised the required method  The results became Chadwick's first paper, which, co-authored with Rutherford, was published in 1912  He graduated with first class honours in 1911 Having devised a means of measuring gamma radiation, Chadwick proceeded to measure the absorption of gamma rays by various gases and liquids  This time the resulting paper was published under his name alone  He was awarded his Master of Science (MSc) degree in 1912, and was appointed a Beyer Fellow  The following year he was awarded an 1851 Exhibition Scholarship, which allowed him to study and research at a university in continental Europe  He elected to go to the Physikalisch-Technische Reichsanstalt in Berlin in 1913, to study beta radiation under Hans Geiger  Using Geiger's recently developed Geiger counter, which provided more accuracy than the earlier photographic techniques, he was able to demonstrate that beta radiation did not produce discrete lines, as has been previously thought, but rather a continuous spectrum with peaks in certain regions  On a visit to Geiger's laboratory, Albert Einstein told Chadwick that: "I can explain either of these things, but I can't explain them both at the same time " The continuous spectrum would remain an unexplained phenomenon for many years Chadwick was still in Germany at the start of the First World War, and was interned in the Ruhleben internment camp near Berlin, where he was allowed to set up a laboratory in the stables and conduct scientific experiments using improvised materials such as radioactive toothpaste  With the help of Charles Drummond Ellis, he worked on the ionisation of phosphorus, and the photochemical reaction of carbon monoxide and chlorine  He was released after the Armistice with Germany came into effect in November 1918, and returned to his parents' home in Manchester, where he wrote up his findings over the previous four years for the 1851 Exhibition commissioners Rutherford gave Chadwick a part-time teaching position at Manchester, allowing him to continue research  He looked at the nuclear charge of platinum, silver, and copper, and experimentally found that this was the same as the atomic number within an error of less than 1 5 per cent  In April 1919, Rutherford became director of the Cavendish Laboratory at the University of Cambridge, and Chadwick joined him there a few months later  Chadwick was awarded a Clerk-Maxwell studentship in 1920, and enrolled as a Doctor of Philosophy (PhD) student at Gonville and Caius College, Cambridge  The first half of his thesis was his work with atomic numbers  In the second, he looked at the forces inside the nucleus  His degree was awarded in June 1921  In November, he became a Fellow of Gonville and Caius College 

Researcher
Cambridge
Chadwick's Clerk-Maxwell studentship expired in 1923, and he was succeeded by the Russian physicist Pyotr Kapitza  The Chairman of the Advisory Council of the Department of Scientific and Industrial Research, Sir William McCormick arranged for Chadwick to become Rutherford's assistant director of research  In this role, Chadwick helped Rutherford select PhD students  Over the next few years these would include John Cockcroft, Norman Feather and Mark Oliphant, who would become firm friends with Chadwick  As many students had no idea what they wanted to research, Rutherford and Chadwick would suggest topics  Chadwick edited all the papers produced by the laboratory 

In 1925, Chadwick met Aileen Stewart-Brown, the daughter of a Liverpool stockbroker  The two were married in August 1925, with Kapitza as Best Man  The couple had twin daughters, Joanna and Judith, who were born in February 1927 In his research, Chadwick continued to probe the nucleus  In 1925, the concept of spin had allowed physicists to explain the Zeeman effect, but it also created unexplained anomalies  At the time it was believed that the nucleus consisted of protons and electrons, so nitrogen's nucleus, for example, with a mass number of 14, was assumed to contain 14 protons and 7 electrons  This gave it the right mass and charge, but the wrong spin At a conference at Cambridge on beta particles and gamma rays in 1928, Chadwick met Geiger again  Geiger had brought with him a new model of his Geiger counter, which had been improved by his post-doctoral student Walther Müller  Chadwick had not used one since the war, and the new Geiger–Müller counter was potentially a major improvement over the scintillation techniques then in use at Cambridge, which relied on the human eye for observation  The major drawback with it was that it detected alpha, beta and gamma radiation, and radium, which the Cavendish laboratory normally used in its experiments, emitted all three, and was therefore unsuitable for what Chadwick had in mind  However, polonium is an alpha emitter, and Lise Meitner sent Chadwick about 2 millicuries (about 0 5 μg) from Germany In Germany, Walther Bothe and his student Herbert Becker had used polonium to bombard beryllium with alpha particles, producing an unusual form of radiation  Chadwick had his Australian 1851 Exhibition scholar, Hugh Webster, duplicate their results  To Chadwick, this was evidence of something that he and Rutherford had been hypothesising for years: the neutron, a theoretical nuclear particle with no electric charge  Then in January 1932, Feather drew Chadwick's attention to another surprising result  Frédéric and Irène Joliot-Curie had succeeded in knocking protons from paraffin wax using polonium and beryllium as a source for what they thought was gamma radiation  Rutherford and Chadwick disagreed; protons were too heavy for that  But neutrons would need only a small amount of energy to achieve the same effect  In Rome, Ettore Majorana came to the same conclusion: the Joliot-Curies had discovered the neutron but did not know it 

Chadwick dropped all his other responsibilities to concentrate on proving the existence of the neutron, assisted by Feather and frequently working late at night  He devised a simple apparatus that consisted of a cylinder containing a polonium source and beryllium target  The resulting radiation could then be directed at a material such as paraffin wax; the displaced particles, which were protons, would go into a small ionisation chamber where they could be detected with an oscilloscope 
In February 1932, after only about two weeks of experimentation with neutrons, Chadwick sent a letter to Nature titled "Possible Existence of a Neutron"  He communicated his findings in detail in an article sent to Proceedings of the Royal Society A titled "The Existence of a Neutron" in May  His discovery of the neutron was a milestone in understanding the nucleus  Reading Chadwick's paper, Robert Bacher and Edward Condon realised that anomalies in the then-current theory, like the spin of nitrogen, would be resolved if the neutron has a spin of 1/2 and that a nitrogen nucleus consisted of seven protons and seven neutrons The theoretical physicists Niels Bohr and Werner Heisenberg considered whether the neutron could be a fundamental nuclear particle like the proton and electron, rather than a proton–electron pair   Heisenberg showed that the neutron was best described as a new nuclear particle, but its exact nature remained unclear   In his 1933 Bakerian Lecture, Chadwick estimated that a neutron had a mass of about 1 0067 u  Since a proton and an electron had a combined mass of 1 0078 u, this implied the neutron as a proton–electron composite had a binding energy of about 2 MeV, which sounded reasonable, although it was hard to understand how a particle with so little binding energy could be stable   Estimating such a small mass difference required challenging precise measurements, however, and several conflicting results were obtained in 1933–4   By bombarding boron with alpha particles, Frédéric and Irène Joliot-Curie obtained a large value for the mass of a neutron, but Ernest Lawrence's team at the University of California produced a small one   Then Maurice Goldhaber, a refugee from Nazi Germany and a graduate student at the Cavendish Laboratory, suggested to Chadwick that deuterons could be photodisintegrated by the 2 6 MeV gamma rays of 208Tl (then known as thorium C"):

An accurate value for the mass of the neutron could be determined from this process  Chadwick and Goldhaber tried this and found that it worked   They measured the kinetic energy of the proton produced as 1 05 MeV, leaving the mass of the neutron as the unknown in the equation   Chadwick and Goldhaber calculated that it was either 1 0084 or 1 0090 atomic units, depending on the values used for the masses of the proton and deuteron   (The modern accepted value for the mass of the neutron is 1 00866 u ) The mass of the neutron was too large to be a proton–electron pair For his discovery of the neutron, Chadwick was awarded the Hughes Medal by the Royal Society in 1932, the Nobel Prize in Physics in 1935, the Copley Medal in 1950 and the Franklin Medal in 1951  His discovery of the neutron made it possible to produce elements heavier than uranium in the laboratory by the capture of slow neutrons followed by beta decay  Unlike the positively charged alpha particles, which are repelled by the electrical forces present in the nuclei of other atoms, neutrons do not need to overcome any Coulomb barrier, and can therefore penetrate and enter the nuclei of even the heaviest elements such as uranium  This inspired Enrico Fermi to investigate the nuclear reactions brought about by collisions of nuclei with slow neutrons, work for which Fermi would receive the Nobel Prize in 1938 Wolfgang Pauli proposed another kind of particle on 4 December 1930 in order to explain the continuous spectrum of beta radiation that Chadwick had reported in 1914  Since not all of the energy of beta radiation could be accounted for, the law of conservation of energy appeared to be violated, but Pauli argued that this could be redressed if another, undiscovered, particle was involved  Pauli also called this particle a neutron, but it was clearly not the same particle as Chadwick's neutron  Fermi renamed it the neutrino, Italian for "little neutron"  In 1934, Fermi proposed his theory of beta decay which explained that the electrons emitted from the nucleus were created by the decay of a neutron into a proton, an electron, and a neutrino   The neutrino could account for the missing energy, but a particle with little mass and no electric charge was difficult to observe  Rudolf Peierls and Hans Bethe calculated that neutrinos could easily pass through the Earth, so the chances of detecting them were slim  Frederick Reines and Clyde Cowan would confirm the neutrino on 14 June 1956 by placing a detector within a large antineutrino flux from a nearby nuclear reactor 

Liverpool
With the onset of the Great Depression in the United Kingdom, the government became more parsimonious with funding for science  At the same time, Lawrence's recent invention, the cyclotron, promised to revolutionise experimental nuclear physics, and Chadwick felt that the Cavendish laboratory would fall behind unless it also acquired one  He therefore chafed under Rutherford, who clung to the belief that good nuclear physics could still be done without large, expensive equipment, and turned down the request for a cyclotron 

Chadwick was himself a critic of Big Science in general, and Lawrence in particular, whose approach he considered careless and focused on technology at the expense of science  When Lawrence postulated the existence of a new and hitherto unknown particle that he claimed was a possible source of limitless energy at the Solvay Conference in 1933, Chadwick responded that the results were more likely attributable to contamination of the equipment  While Lawrence rechecked his results at Berkeley only to find that Chadwick was correct, Rutherford and Oliphant conducted an investigation at the Cavendish that found that deuterium fuses to form helium-3, thereby causing the effect that Lawrence had observed  This was another major discovery, but the Oliphant-Rutherford particle accelerator was an expensive state-of-the-art piece of equipment In March 1935, Chadwick received an offer of the Lyon Jones Chair of physics at the University of Liverpool, in his wife's home town, to succeed Lionel Wilberforce  The laboratory was so antiquated that it still ran on direct current electricity, but Chadwick seized the opportunity, assuming the chair on 1 October 1935  The university's prestige was soon bolstered by Chadwick's Nobel Prize, which was announced in November 1935  His medal was sold at auction in 2014 for $329,000 Chadwick set about acquiring a cyclotron for Liverpool  He started by spending £700 to refurbish the antiquated laboratories at Liverpool, so some components could be made in-house  He was able to persuade the university to provide £2,000 and obtained a grant for another £2,000 from the Royal Society  To build his cyclotron, Chadwick brought in two young experts, Bernard Kinsey and Harold Walke, who had worked with Lawrence at the University of California  A local cable manufacturer donated the copper conductor for the coils  The cyclotron's 50-ton magnet was manufactured in Trafford Park by Metropolitan-Vickers, which also made the vacuum chamber  The cyclotron was completely installed and running in July 1939  The total cost of £5,184 was more than Chadwick had received from the University and the Royal Society, so Chadwick paid the rest from his 159,917 kr (£8,243) Nobel Prize money At Liverpool the Medicine and Science faculties worked together closely  Chadwick was automatically a committee member of both faculties, and in 1938 he was appointed to a commission headed by Lord Derby to investigate the arrangements for cancer treatment in Liverpool  Chadwick anticipated that neutrons and radioactive isotopes produced with the 37-inch cyclotron could be used to study biochemical processes, and might become a weapon in the fight against cancer 

Second World War
Tube Alloys and the MAUD Report
In Germany, Otto Hahn and Fritz Strassmann bombarded uranium with neutrons, and noted that barium, a lighter element, was among the products produced  Hitherto, only the same or heavier elements had been produced by the process  In January 1939, Meitner and her nephew Otto Frisch astounded the physics community with a paper that explained this result  They theorised that uranium atoms bombarded with neutrons can break into two roughly equal fragments, a process they called fission  They calculated that this would result in the release of about 200 MeV, implying an energy release orders of magnitude greater than chemical reactions, and Frisch confirmed their theory experimentally  It was soon noted by Hahn that if neutrons were released during fission, then a chain reaction was possible  French scientists, Pierre Joliot, Hans von Halban and Lew Kowarski, soon verified that more than one neutron was indeed emitted per fission  In a paper co-authored with the American physicist John Wheeler, Bohr theorised that fission was more likely to occur in the uranium-235 isotope, which made up only 0 7 percent of natural uranium 

Chadwick did not believe that there was any likelihood of another war with Germany in 1939, and took his family for a holiday on a remote lake in northern Sweden  The news of the outbreak of the Second World War therefore came as a shock  Determined not to spend another war in an internment camp, Chadwick made his way to Stockholm as fast as he could, but when he arrived there with his family, he found that all air traffic between Stockholm and London had been suspended  They made their way back to England on a tramp steamer  When he reached Liverpool, Chadwick found Joseph Rotblat, a Polish post-doctoral fellow who had come to work with the cyclotron, was now destitute, as he was cut off from funds from Poland  Chadwick promptly hired Rotblat as a lecturer, despite his poor grasp of English In October 1939, Chadwick received a letter from Sir Edward Appleton, the Secretary of the Department of Scientific and Industrial Research, asking for his opinion on the feasibility of an atom bomb  Chadwick responded cautiously  He did not dismiss the possibility, but carefully went over the many theoretical and practical difficulties involved  Chadwick decided to investigate the properties of uranium oxide further with Rotblat  In March 1940, Otto Frisch and Rudolf Peierls at the University of Birmingham re-examined the theoretical issues involved in a paper that became known as the Frisch–Peierls memorandum  Instead of looking at unenriched uranium oxide, they considered what would happen to a sphere of pure uranium-235, and found that not only could a chain reaction occur, but that it might require as little as 1 kilogram (2 2 lb) of uranium-235, and unleash the energy of tons of dynamite 

A special subcommittee of the Committee for the Scientific Survey of Air Warfare (CSSAW), known as the MAUD Committee, was created to investigate the matter further  It was chaired by Sir George Thomson and its original membership included Chadwick, along with Mark Oliphant, John Cockcroft and Philip Moon  While other teams investigated uranium enrichment techniques, Chadwick's team at Liverpool concentrated on determining the nuclear cross section of uranium-235  By April 1941, it had been experimentally confirmed that the critical mass of uranium-235 might be 8 kilograms (18 lb) or less  His research into such matters was complicated by all-but-incessant Luftwaffe bombings of the environs of his Liverpool lab; the windows were blown out so often that they were replaced by cardboard In July 1941, Chadwick was chosen to write the final draft of the MAUD Report, which, when presented by Vannevar Bush to President Franklin D  Roosevelt in October 1941, inspired the U S  government to pour millions of dollars into the pursuit of an atom bomb  When George B  Pegram and Harold Urey visited Britain to see how the project, now known as Tube Alloys, was going, Chadwick was able to tell them: "I wish I could tell you that the bomb is not going to work, but I am 90 per cent sure that it will "In a recent book about the Bomb project, Graham Farmelo wrote that "Chadwick did more than any other scientist to give Churchill the Bomb      Chadwick was tested almost to the breaking point " So worried that he could not sleep, Chadwick resorted to sleeping pills, which he continued to take for most of his remaining years  Chadwick later said that he realised that "a nuclear bomb was not only possible—it was inevitable  Sooner or later these ideas could not be peculiar to us  Everybody would think about them before long, and some country would put them into action"  Sir Hermann Bondi suggested that it was fortunate that Chadwick, not Rutherford, was the doyen of UK physics at the time, as the latter's prestige might otherwise have overpowered Chadwick's interest in "looking forward" to the Bomb's prospects 

Manhattan Project
Owing to the danger from aerial bombardment, the Chadwicks sent their twins to Canada as part of a government evacuation scheme  Chadwick was reluctant to move Tube Alloys there, believing that the United Kingdom was a better location for the isotope separation plant  The enormous scope of the effort became more apparent in 1942: even a pilot separation plant would cost over £1 million and strain Britain's resources, to say nothing of a full-scale plant, which was estimated to cost somewhere in the vicinity of £25 million  It would have to be built in America  At the same time that the British became convinced that a joint project was necessary, the progress of the American Manhattan Project was such that British cooperation seemed less essential, although the Americans were still eager to utilise Chadwick's talents The matter of cooperation had to be taken up at the highest level  In September 1943, the Prime Minister, Winston Churchill, and President Roosevelt negotiated the Quebec Agreement, which reinstated cooperation between Britain, the United States and Canada  Chadwick, Oliphant, Peierls and Simon were summoned to the United States by the director of Tube Alloys, Sir Wallace Akers, to work with the Manhattan Project  The Quebec Agreement established a new Combined Policy Committee to direct the joint project  The Americans disliked Akers, so Chadwick was appointed technical advisor to the Combined Policy Committee, and the head of the British Mission Leaving Rotblat in charge in Liverpool, Chadwick began a tour of the Manhattan Project facilities in November 1943, except for the Hanford Site where plutonium was produced, which he was not allowed to see  He became the only man apart from Groves and his second in command to have access to all the American research and production facilities for the uranium bomb  Observing the work on the K-25 gaseous diffusion facility at Oak Ridge, Tennessee, Chadwick realised how wrong he had been about building the plant in wartime Britain  The enormous structure could never have been concealed from the Luftwaffe  In early 1944, he moved to Los Alamos, New Mexico, with his wife and their twins, who now spoke with Canadian accents  For security reasons, he was given the cover name of James Chaffee 

Chadwick accepted that the Americans did not need British help, but that it could still be useful in bringing the project to an early and successful conclusion  Working closely with the director of the Manhattan Project, Major General Leslie R  Groves, Jr , he attempted to do everything he could to support the effort  He also endeavoured to place British scientists in as many parts of the project as possible in order to facilitate a post-war British nuclear weapons project to which Chadwick was committed  Requests from Groves via Chadwick for particular scientists tended to be met with an immediate rejection by the company, ministry or university currently employing them, only to be overcome by the overriding priority accorded to Tube Alloys  As a result, the British team was critical to the Project's success Although he had more knowledge of the project than anyone else from Britain, Chadwick had no access to the Hanford site  Lord Portal was offered a tour of Hanford in 1946  "This was the only plant to which Chadwick had been denied access in wartime, and now he asked Groves if he could accompany Portal  Groves replied that he could, but if he did then 'Portal will not see very much' " For his efforts, Chadwick received a knighthood in the New Year Honours on 1 January 1945  He considered this to be a recognition of the work of the whole Tube Alloys project By early 1945, Chadwick was spending most of his time in Washington, D C , and his family relocated from Los Alamos to a house on Washington's Dupont Circle in April 1945  He was present at the meeting of the Combined Policy Committee on 4 July when Field Marshal Sir Henry Maitland Wilson gave Britain's agreement to use the atom bomb against Japan, and at the Trinity nuclear test on 16 July, when the first atom bomb was detonated  Inside its pit was a polonium-beryllium modulated neutron initiator, a development of the technique that Chadwick had used to discover the neutron over a decade before  William L  Laurence, The New York Times reporter attached to the Manhattan Project, wrote that "never before in history had any man lived to see his own discovery materialize itself with such telling effect on the destiny of man "

Later life
Shortly after the war ended, Chadwick was appointed to the Advisory Committee on Atomic Energy (ACAE)  He was also appointed as the British scientific advisor to the United Nations Atomic Energy Commission  He clashed with fellow ACAE member Patrick Blackett, who disagreed with Chadwick's conviction that Britain needed to acquire its own nuclear weapons; but it was Chadwick's position that was ultimately adopted  He returned to Britain in 1946, to find a country still beset by wartime rationing and shortages At this time, Sir James Mountford, the Vice Chancellor of the University of Liverpool, wrote in his diary "he had never seen a man 'so physically, mentally and spiritually tired" as Chadwick, for he "had plumbed such depths of moral decision as more fortunate men are never called upon even to peer into     [and suffered]     almost insupportable agonies of responsibility arising from his scientific work' "In 1948, Chadwick accepted an offer to become the Master of Gonville and Caius College  The job was prestigious but ill-defined; the Master was the titular head of the College, but authority actually resided in a council of 13 fellows, of whom one was the Master  As Master, Chadwick strove to improve the academic reputation of the college  He increased the number of research fellowships from 31 to 49, and sought to bring talent into the college  This involved controversial decisions, such as hiring in 1951 the Chinese biochemist Tien-chin Tsao and the Hungarian-born economist Peter Bauer  In what became known as the Peasants' Revolt, fellows led by Patrick Hadley voted an old friend of Chadwick's off the council and replaced him with Bauer  More friends of Chadwick's were removed over the following years, and he retired in November 1958  It was during his mastership that Francis Crick, a PhD student at Gonville and Caius College, and James Watson discovered the structure of DNA Over the years, Chadwick received many honours, including the Medal for Merit from the United States, and the Pour le Mérite from Germany  He was elected a Fellow of the Royal Society in 1927  He became a foreign member of the Royal Netherlands Academy of Arts and Sciences in 1946 and an International member of the American Philosophical Society in 1948  He was made a Companion of Honour in the New Year Honours on 1 January 1970 for "services to science", and went to Buckingham Palace for the investiture ceremony  He became more frail, and seldom left his flat, although he travelled to Liverpool for celebrations of his eightieth birthday   A lifelong atheist, he saw no reason to adopt religious faith in later life  He died in his sleep on 24 July 1974 His papers are held at the Churchill Archives Centre in Cambridge, and are accessible to the public  The Chadwick Laboratory at the University of Liverpool is named after him, as is its Sir James Chadwick Chair of Experimental Physics, which was named after him in 1991 as part of celebrations of the centenary of his birth  A crater on the moon is also named after him  The James Chadwick Building, which houses part of the School of Chemical Engineering and Analytical Sciences, University of Manchester is named in his honour  He was described by the United Kingdom Atomic Energy Authority official historian Lorna Arnold as "a physicist, a scientist-diplomat, and a good, wise, and humane man "

Notes
Passage 2:
Neutron temperature
The neutron detection temperature, also called the neutron energy, indicates a free neutron's kinetic energy, usually given in electron volts  The term temperature is used, since hot, thermal and cold neutrons are moderated in a medium with a certain temperature  The neutron energy distribution is then adapted to the Maxwell distribution known for thermal motion  Qualitatively, the higher the temperature, the higher the kinetic energy of the free neutrons  The momentum and wavelength of the neutron are related through the de Broglie relation  The large wavelength of slow neutrons allows for the large cross section 

Neutron energy distribution ranges
But different ranges with different names are observed in other sources The following is a detailed classification:

Thermal
A thermal neutron is a free neutron with a kinetic energy of about 0 025 eV (about 4 0×10−21 J or 2 4 MJ/kg, hence a speed of 2 19 km/s), which is the energy corresponding to the most probable speed at a temperature of 290 K (17 °C or 62 °F), the mode of the Maxwell–Boltzmann distribution for this temperature, Epeak = 1/2 k T 
After a number of collisions with nuclei (scattering) in a medium (neutron moderator) at this temperature, those neutrons which are not absorbed reach about this energy level 
Thermal neutrons have a different and sometimes much larger effective neutron absorption cross-section for a given nuclide than fast neutrons, and can therefore often be absorbed more easily by an atomic nucleus, creating a heavier, often unstable isotope of the chemical element as a result  This event is called neutron activation 

EpithermalNeutrons of energy greater than thermal
Greater than 0 025 eV

CadmiumNeutrons which are strongly absorbed by cadmium
Less than 0 5 eV 

EpicadmiumNeutrons which are not strongly absorbed by cadmium
Greater than 0 5 eV 

Cold (slow) neutronsNeutrons of lower (much lower) energy than thermal neutrons 
Less than 5 meV 
Cold (slow) neutrons are subclassified into cold (CN), very cold (VCN), and ultra-cold (UCN) neutrons, each having particular characteristics in terms of their optical interactions with matter  As the wavelength is made (chosen to be) longer,  lower values of the momentum exchange become accessible  Therefore, it is possible to study larger scales and slower dynamics  Gravity also plays a very significant role in the case of UCN  Nevertheless, UCN reflect at all angles of incidence  This is because their momentum is comparable to the optical potential of materials  This effect is used to store them in bottles and study their fundamental properties e g  lifetime, neutron electrical-dipole moment etc    The main limitations of the use of slow neutrons is the low flux and the lack of efficient optical devices (in the case of CN and VCN)  Efficient neutron optical components are being developed and optimized to remedy this lack 

ResonanceRefers to neutrons which are strongly susceptible to non-fission capture by U-238 
1 eV to 300 eV

IntermediateNeutrons that are between slow and fast
Few hundred eV to 0 5 MeV 

Fast
A fast neutron is a free neutron with a kinetic energy level close to 1 MeV (100 TJ/kg), hence a speed of 14,000 km/s or higher  They are named fast neutrons to distinguish them from lower-energy thermal neutrons, and high-energy neutrons produced in cosmic showers or accelerators Fast neutrons are produced by nuclear processes:

Nuclear fission produces neutrons with a mean energy of 2 MeV (200 TJ/kg, i e  20,000 km/s), which qualifies as "fast"  However the range of neutrons from fission follows a Maxwell–Boltzmann distribution from 0 to about 14 MeV in the center of momentum frame of the disintegration, and the mode of the energy is only 0 75 MeV, meaning that fewer than half of fission neutrons qualify as "fast" even by the 1 MeV criterion 
Spontaneous fission is a mode of radioactive decay for some heavy nuclides  Examples include plutonium-240 and californium-252 
Nuclear fusion: deuterium–tritium fusion produces neutrons of 14 1 MeV (1400 TJ/kg, i e  52,000 km/s, 17 3% of the speed of light) that can easily fission uranium-238 and other non-fissile actinides 
Neutron emission occurs in situations in which a nucleus contains enough excess neutrons that the separation energy of one or more neutrons becomes negative (i e  excess neutrons "drip" out of the nucleus)  Unstable nuclei of this sort will often decay in less than one second Fast neutrons are usually undesirable in a steady-state nuclear reactor because most fissile fuel has a higher reaction rate with thermal neutrons  Fast neutrons can be rapidly changed into thermal neutrons via a process called moderation  This is done through numerous collisions with (in general) slower-moving and thus lower-temperature particles like atomic nuclei and other neutrons  These collisions will generally speed up the other particle and slow down the neutron and scatter it  Ideally, a room temperature neutron moderator is used for this process  In reactors, heavy water, light water, or graphite are typically used to moderate neutrons 

UltrafastRelativistic
Greater than 20 MeV

Other classifications
Pile

Neutrons of all energies present in nuclear reactors
0 001 eV to 15 MeV Ultracold

Neutrons with sufficiently low energy to be reflected and trapped
Upper bound of 335 neV

Fast-neutron reactor and thermal-neutron reactor compared
Most fission reactors are thermal-neutron reactors that use a neutron moderator to slow down ("thermalize") the neutrons produced by nuclear fission  Moderation substantially increases the fission cross section for fissile nuclei such as uranium-235 or plutonium-239  In addition, uranium-238 has a much lower capture cross section for thermal neutrons, allowing more neutrons to cause fission of fissile nuclei and propagate the chain reaction, rather than being captured by 238U  The combination of these effects allows light water reactors to use low-enriched uranium  Heavy water reactors and graphite-moderated reactors can even use natural uranium as these moderators have much lower neutron capture cross sections than light water An increase in fuel temperature also raises uranium-238's thermal neutron absorption by Doppler broadening, providing negative feedback to help control the reactor  When the coolant is a liquid that also contributes to moderation and absorption (light water or heavy water), boiling of the coolant will reduce the moderator density, which can provide positive or negative feedback (a positive or negative void coefficient), depending on whether the reactor is under- or over-moderated 
Intermediate-energy neutrons have poorer fission/capture ratios than either fast or thermal neutrons for most fuels  An exception is the uranium-233 of the thorium cycle, which has a good fission/capture ratio at all neutron energies 
Fast-neutron reactors use unmoderated fast neutrons to sustain the reaction, and require the fuel to contain a higher concentration of fissile material relative to fertile material (uranium-238)  However, fast neutrons have a better fission/capture ratio for many nuclides, and each fast fission releases a larger number of neutrons, so a fast breeder reactor can potentially "breed" more fissile fuel than it consumes 
Fast reactor control cannot depend solely on Doppler broadening or on negative void coefficient from a moderator  However, thermal expansion of the fuel itself can provide quick negative feedback  Perennially expected to be the wave of the future, fast reactor development has been nearly dormant with only a handful of reactors built in the decades since the Chernobyl accident due to low prices in the uranium market, although there is now a revival with several Asian countries planning to complete larger prototype fast reactors in the next few years

Discovery of the neutron
The discovery of the neutron and its properties was central to the extraordinary developments in atomic physics in the first half of the 20th century  Early in the century, Ernest Rutherford developed a crude model of the atom,: 188  based on the gold foil experiment of Hans Geiger and Ernest Marsden  In this model, atoms had their mass and positive electric charge concentrated in a very small nucleus  By 1920, isotopes of chemical elements had been discovered, the atomic masses had been determined to be (approximately) integer multiples of the mass of the hydrogen atom, and the atomic number had been identified as the charge on the nucleus : §1 1 2  Throughout the 1920s, the nucleus was viewed as composed of combinations of protons and electrons, the two elementary particles known at the time, but that model presented several experimental and theoretical contradictions : 298 The essential nature of the atomic nucleus was established with the discovery of the neutron by James Chadwick in 1932 and the determination that it was a new elementary particle, distinct from the proton : 55 The uncharged neutron was immediately exploited as a new means to probe nuclear structure, leading to such discoveries as the creation of new radioactive elements by neutron irradiation (1934) and the fission of uranium atoms by neutrons (1938)  The discovery of fission led to the creation of both nuclear power and nuclear weapons by the end of World War II  Both the proton and the neutron were presumed to be elementary particles until the 1960s, when they were determined to be composite particles built from quarks 

Discovery of radioactivity
At the start of the 20th century, the vigorous debate as to the existence of atoms had not yet been resolved  Philosophers such as Ernst Mach and Wilhelm Ostwald denied that atoms were real, viewing them as a convenient mathematical construct, while scientists such as Arnold Sommerfeld and Ludwig Boltzmann saw that physical theories required the existence of atoms : 13–14 Radioactivity was discovered in 1896 by the French scientist Henri Becquerel, while working with phosphorescent materials   In 1898, Ernest Rutherford at Cavendish Laboratory distinguished two types of radioactivity, alpha rays and beta rays, which differed in their ability to penetrate, or travel into, ordinary objects or gases  Two years later, Paul Villard discovered gamma rays, which possessed even more penetrating power : 8–9  These radiations were soon identified with known particles:  beta rays were shown to be electrons by Walter Kaufmann in 1902; alpha rays were shown to be helium ions by Rutherford and Thomas Royds in 1907; and gamma rays were shown to be electromagnetic radiation, that is, a form of light, by Rutherford and Edward Andrade in 1914 : 61–62, 87  These radiations had also been identified as emanating from atoms, hence they provided clues to processes occurring within atoms   Conversely, the radiations were also recognized as tools that could be exploited in scattering experiments to probe the interior of atoms : 112–115

The gold foil experiment and the discovery of the atomic nucleus
At the University of Manchester between 1908 and 1913, Rutherford directed Hans Geiger and Ernest Marsden in a series of experiments to determine what happens when alpha particles scatter from metal foil  Now called the Rutherford gold foil experiment, or the Geiger–Marsden experiment, these measurements made the extraordinary discovery that although most alpha particles passing through a thin gold foil experienced little deflection, a few scattered to a high angle  The scattering indicated that some of the alpha particles ricocheted back from a small, but dense, component inside the atoms  Based on these measurements, by 1911 it was apparent to Rutherford that the atom consisted of a small, massive nucleus with positive charge surrounded by a much larger cloud of negatively charged electrons  The concentrated atomic mass was required to provide the observed deflection of the alpha particles, and Rutherford developed a mathematical model that accounted for the scattering The Rutherford model was very influential, motivating the Bohr model for electrons orbiting the nucleus in 1913 and eventually leading to quantum mechanics by the mid-1920s 

Discovery of isotopes
Concurrent with the work of Rutherford, Geiger, and Marsden, the radiochemist Frederick Soddy at the University of Glasgow was studying chemistry related problems on radioactive materials  Soddy had worked with Rutherford on radioactivity at McGill University  By 1910, about 40 different radioactive elements, referred to as radioelements, had been identified between uranium and lead, although the periodic table only allowed for 11 elements  Soddy and Kazimierz Fajans independently found in 1913 that an element undergoing alpha decay will produce an element two places to the left in the periodic system and an element undergoing beta decay will produce an element one place to the right in the periodic system   Also, those radioelements that reside in the same places in the periodic system are chemically identical   Soddy called these chemically identical elements  isotopes : 3–5  For his study of radioactivity and the discovery of isotopes, Soddy was awarded the 1921 Nobel Prize in Chemistry 

Building from work by J  J  Thomson on the deflection of positively charged atoms by electric and magnetic fields, Francis Aston built the first mass spectrograph at the Cavendish Laboratory in 1919  His aim, which he easily achieved, was to separate the two isotopes of neon, 20Ne and 22Ne  Aston discovered that the masses of all the particles are whole numbers (the whole number rule): that is, the masses of all the isotopes are whole number multiples of the mass of the hydrogen atom  In these measurements, Aston arbitrarily computed his masses relative to oxygen-16, which he took to have a mass of exactly 16  (Today the atomic mass unit (amu) is relative to carbon-12 ) Ironically, the one exception to this rule was hydrogen itself, which had a mass value of 1 008  The excess mass was small, but well outside the limits of experimental uncertainty  Aston and others quickly realized that the discrepancy is due to the binding energy of atoms, that is, the mass of a number of hydrogen atoms bound into a single atom must be less than the sum of the masses of the separate hydrogen atoms   Aston's work on isotopes won him the 1922 Nobel Prize in Chemistry for the discovery of isotopes in a large number of non-radioactive elements, and for his enunciation of the whole number rule  Noting Aston's recent discovery of nuclear binding energy, in 1920 Arthur Eddington suggested that stars may obtain their energy by fusing hydrogen (protons) into helium and that the heavier elements may form in stars 

Atomic number and Moseley's law
Rutherford and others had noted the disparity between the mass of an atom, computed in atomic mass units, and the approximate charge required on the nucleus for the Rutherford model to work  The required charge of the atomic nucleus was usually about half its atomic mass : 82 Antonius van den Broek boldly hypothesized that the required charge, denoted by Z, was not half of the atomic weight for elements, but instead was exactly equal to the element's ordinal position in the periodic table : 228  At that time, the positions of the elements in the periodic table were not known to have any physical significance   If the elements were ordered based on increasing atomic mass, however, periodicity in chemical properties was exhibited   Exceptions to this periodicity were apparent, however, such as cobalt and nickel : 180 At the University of Manchester in 1913 Henry Moseley discussed the new Bohr model of the atom with the visiting Bohr  The model accounted for the electromagnetic emission spectrum from the hydrogen atom, and Moseley and Bohr wondered if the electromagnetic emission spectra of heavier elements such as cobalt and nickel would follow their ordering by weight, or by their position in the periodic table : 346  In 1913–1914 Moseley tested the question experimentally by using X-ray diffraction techniques  He found that the most intense short-wavelength line in the X-ray spectrum of a particular element, known as the K-alpha line, was related to the element's position in the periodic table, that is, its atomic number, Z  Indeed, Moseley introduced this nomenclature : §1 1 2  Moseley found that the frequencies of the radiation were related in a simple way to the atomic number of the elements for a large number of elements : 5 : 181 Within a year it was noted that the equation for the relation, now called Moseley's law, could be explained in terms of the 1913 Bohr model, with reasonable extra assumptions about atomic structure in other elements : 87  Moseley's result, by Bohr's later account, not only established atomic number as a measurable experimental quantity, but gave it a physical meaning as the positive charge on the atomic nucleus  The elements could be ordered in the periodic system in order of atomic number, rather than atomic weight : 127  The result tied together the organization of the periodic table, the Bohr model for the atom,: 56  and Rutherford's model for alpha scattering from nuclei  It was cited by Rutherford, Bohr, and others as a critical advance in understanding the nature of the atomic nucleus Further research in atomic physics was interrupted by the outbreak of World War I  Moseley was killed in 1915 at the Battle of Gallipoli,: 182  while Rutherford's student James Chadwick was interned in Germany for the duration of the war, 1914–1918  In Berlin, Lise Meitner's and Otto Hahn's research work on determining the radioactive decay chains of radium and uranium by precise chemical separation was interrupted : §4  Meitner spent much of the war working as a radiologist and medical X-ray technician near the Austrian front, while Hahn, a chemist, worked on research in poison gas warfare : 61–62, 68

Rutherford atom
In 1920 Rutherford gave a Bakerian lecture at the Royal Society entitled the "Nuclear Constitution of Atoms", a summary of recent experiments on atomic nuclei and conclusions as to the structure of atomic nuclei : 23 : 5  By 1920, the existence of electrons within the atomic nucleus was widely assumed   It was assumed the nucleus consisted of hydrogen nuclei in number equal to the atomic mass   But since each hydrogen nucleus had charge +1, the nucleus required a smaller number of "internal electrons" each of charge −1 to give the nucleus its correct total charge  The mass of protons is about 1800 times greater than that of electrons, so the mass of the electrons is incidental in this computation : 230–231   Such a model was consistent with the scattering of alpha particles from heavy nuclei, as well as the charge and mass of the many isotopes that had been identified   There were other motivations for the proton–electron model   As noted by Rutherford at the time, "We have strong reason for believing that the nuclei of atoms contain electrons as well as positively charged bodies   ",: 376–377  namely, it was known that beta radiation was electrons emitted from the nucleus : 21 : 5–6 In that lecture, Rutherford conjectured the existence of new particles   The alpha particle was known to be very stable, and it was assumed to retain its identity within the nucleus   The alpha particle was presumed to consist of four protons and two closely bound electrons to give it +2 charge and mass 4   In a 1919 paper, Rutherford had reported the apparent discovery of a new doubly charged particle of mass 3, denoted the X++, interpreted to consist of three protons and a closely bound electron   This result suggested to Rutherford the likely existence of two new particles: one of two protons with a closely bound electron, and another of one proton and a closely bound electron  The X++ particle was later determined to have mass 4 and to be just a low-energy alpha particle : 25  Nevertheless, Rutherford had conjectured the existence of the deuteron, a +1 charge particle of mass 2, and the neutron, a neutral particle of mass 1 : 396   The former is the nucleus of deuterium, discovered in 1931 by Harold Urey  The mass of the hypothetical neutral particle would be little different from that of the proton  Rutherford determined that such a zero-charge particle would be difficult to detect by available techniques : 396 About the time of Rutherford's lecture, other publications appeared with similar suggestions of a proton–electron composite in the nucleus, and in 1921 William Harkins, an American chemist, named the uncharged particle the neutron : 6  About that same time the word proton was adopted for the hydrogen nucleus   Neutron was apparently constructed from the Latin root for neutral and the Greek ending -on (by imitation of electron and proton)  References to the word neutron in connection with the atom can be found in the literature as early as 1899, however : 398 Rutherford and Chadwick immediately began an experimental program at the Cavendish Laboratory in Cambridge to search for the neutron : 27 : 398   The experiments continued throughout the 1920s without success Rutherford's conjecture and the hypothetical "neutron" were not widely accepted   In his 1931 monograph on the Constitution of Atomic Nuclei and Radioactivity, George Gamow, then at the Institute for Theoretical Physics in Copenhagen, did not mention the neutron   At the time of their 1932 measurements in Paris that would lead to the discovery of the neutron, Irène Joliot-Curie and Frédéric Joliot were unaware of the conjecture 

Problems of the nuclear electrons hypothesis
Throughout the 1920s, physicists assumed that the atomic nucleus was composed of protons and "nuclear electrons" : 29–32  Under this hypothesis, the nitrogen-14 (14N) nucleus would be composed of 14 protons and 7 electrons, so that it would have a net charge of +7 elementary charge units and a mass of 14 atomic mass units  This nucleus would also be orbited by another 7 electrons, termed "external electrons" by Rutherford,: 375  to complete the 14N atom  However problems with the hypothesis soon became apparent 
Ralph Kronig pointed out in 1926 that the observed hyperfine structure of atomic spectra was inconsistent with the proton–electron hypothesis  This structure is caused by the influence of the nucleus on the dynamics of orbiting electrons  The magnetic moments of supposed "nuclear electrons" should produce hyperfine spectral line splittings similar to the Zeeman effect, but no such effects were observed : 199   It seemed that the magnetic moment of the electron vanished when it was within the nucleus : 299 While on a visit to Utrecht University in 1928, Kronig learned of a surprising aspect of the rotational spectrum of N2+  The precision measurement made by Leonard Ornstein, the director of Utrecht's Physical Laboratory, showed that the spin of nitrogen nucleus must be equal to one  However, if the nitrogen-14 (14N) nucleus was composed of 14 protons and 7 electrons, an odd number of spin-1/2 particles, then the resultant nuclear spin should be half-integer  Kronig therefore suggested that perhaps "protons and  electrons do not retain their identity to the extent they do outside the nucleus" : 299–301 : 117 Observations of the rotational energy levels of diatomic molecules using Raman spectroscopy by Franco Rasetti in 1929 were inconsistent with the statistics expected from the proton–electron hypothesis  Rasetti obtained band spectra for H2 and N2 molecules   While the lines for both diatomic molecules showed alternation in intensity between light and dark, the pattern of alternation for H2 is opposite to that of the N2  After carefully analyzing these experimental results, German physicists Walter Heitler and Gerhard Herzberg showed that the hydrogen nuclei obey Fermi statistics and the nitrogen nuclei obey Bose statistics  However, a then unpublished result of Eugene Wigner showed that a composite system with an odd number of spin-1/2 particles must obey Fermi statistics; a system with an even number of spin-1/2 particle obeys Bose statistics  If the nitrogen nucleus had 21 particles, it should obey Fermi statistics, contrary to fact  Thus, Heitler and Herzberg concluded: "the electron in the nucleus     loses its ability to determine the statistics of the nucleus ": 117–118 The Klein paradox, discovered by Oskar Klein in 1928, presented further quantum mechanical objections to the notion of an electron confined within a nucleus   Derived from the Dirac equation, this clear and precise paradox suggested that an  electron approaching a high potential barrier has a high probability of passing through the barrier by a pair creation process   Apparently, an electron could not be confined within a nucleus by any potential well  The meaning of this paradox was intensely debated at the time : 199–200 By about 1930 it was generally recognized that it was difficult to reconcile the proton–electron model for nuclei with the Heisenberg uncertainty relation of quantum mechanics : 199 : 299  This relation, Δx⋅Δp ≥ 1⁄2ħ, implies that an electron confined to a region the size of an atomic nucleus typically has a kinetic energy of about 40 MeV,: 299  which is larger than the observed energy of beta particles emitted from the nucleus  Such energy is also much larger than the binding energy of nucleons,: 89  which Aston and others had shown to be less than 9 MeV per nucleon : 511 In 1927, Charles Ellis and W  Wooster at the Cavendish Laboratory measured the energies of β-decay electrons   They found that the distribution of energies from any particular radioactive nuclei was broad and continuous, a result that contrasted notably with the distinct energy values observed in alpha and gamma decay  Further, the continuous energy distribution seemed to indicate that energy was not conserved by this "nuclear electrons" process   Indeed, in 1929 Bohr proposed to modify the law of energy conservation to account for the continuous energy distribution  The proposal earned the support of Werner Heisenberg  Such considerations were apparently reasonable, inasmuch as the laws of quantum mechanics had so recently overturned the laws of classical mechanics 
While all these considerations did not "prove" an electron could not exist in the nucleus, they were confusing and challenging for physicists to interpret   Many theories were invented to explain how the above arguments could be wrong : 4–5  In his 1931 monograph, Gamow summarized all these contradictions, marking the statements regarding electrons in the nucleus with warning symbols : 23

Discovery of the neutron
In 1930, Walther Bothe and his collaborator Herbert Becker in Giessen, Germany found that if the energetic alpha particles emitted from polonium fell on certain light elements, specifically beryllium (94Be), boron (115B), or lithium (73Li), an unusually penetrating radiation was produced  Beryllium produced the most intense radiation   Polonium is highly radioactive, producing energetic alpha radiation, and it was commonly used for scattering experiments at the time : 99–110  Alpha radiation can be influenced by an electric field, because it is composed of charged particles   The observed penetrating radiation was not influenced by an electric field, however, so it was thought to be gamma radiation  The radiation was more penetrating than any gamma rays known, and the details of experimental results were difficult to interpret 

Two years later Irène Joliot-Curie and Frédéric Joliot in Paris showed that if this unknown radiation fell on paraffin wax, or any other hydrogen-containing compound, it ejected protons of very high energy (5 MeV)  This observation was not in itself inconsistent with the assumed gamma ray nature of the new radiation, but that interpretation (Compton scattering) had a logical problem   From energy and momentum considerations, a gamma ray would have to have impossibly high energy (50 MeV) to scatter a massive proton : §1 3 1  In Rome, the young physicist Ettore Majorana declared that the manner in which the new radiation interacted with
protons required a new neutral particle On hearing of the Paris results, neither Rutherford nor James Chadwick at the Cavendish Laboratory believed the gamma ray hypothesis  Assisted by Norman Feather, Chadwick quickly performed a series of experiments showing that the gamma ray hypothesis was untenable  The previous year, Chadwick, J E R  Constable, and E C  Pollard had already conducted experiments on disintegrating light elements using alpha radiation from polonium  They had also developed more accurate and efficient methods for detecting, counting, and recording the ejected protons  Chadwick repeated the creation of the radiation using beryllium to absorb the alpha particles: 9Be + 4He (α) →  12C + 1n  Following the Paris experiment, he aimed the radiation at paraffin wax, a hydrocarbon high in hydrogen content, hence offering a target dense with protons  As in the Paris experiment, the radiation energetically scattered some of the protons  Chadwick measured the range of these protons, and also measured how the new radiation impacted the atoms of various gases  He found that the new radiation consisted of not gamma rays, but uncharged particles with about the same mass as the proton  These particles were neutrons  Chadwick won the Nobel Prize in Physics in 1935 for this discovery The year 1932 was later referred to as the "annus mirabilis" for nuclear physics in the Cavendish Laboratory, with discoveries of the neutron, artificial nuclear disintegration by the Cockcroft–Walton particle accelerator, and the positron 

Proton–neutron model of the nucleus
Given the problems of the proton–electron model, it was quickly accepted that the atomic nucleus is composed of protons and neutrons, although the precise nature of the neutron was initially unclear  Within months after the discovery of the neutron, Werner Heisenberg and Dmitri Ivanenko had proposed proton–neutron models for the nucleus  Heisenberg's landmark papers approached the description of protons and neutrons in the nucleus through quantum mechanics  While Heisenberg's theory for protons and neutrons in the nucleus was a "major step toward understanding the nucleus as a quantum mechanical system," he still assumed the presence of nuclear electrons  In particular, Heisenberg assumed the neutron was a proton–electron composite, for which there is no quantum mechanical explanation  Heisenberg had no explanation for how lightweight electrons could be bound within the nucleus  Heisenberg introduced the first theory of nuclear exchange forces that bind the nucleons  He considered protons and neutrons to be different quantum states of the same particle, i e , nucleons distinguished by the value of their nuclear isospin quantum numbers 
The proton–neutron model explained the puzzle of dinitrogen  When 14N was proposed to consist of 3 pairs each of protons and neutrons, with an additional unpaired neutron and proton each contributing a spin of 1⁄2 ħ in the same direction for a total spin of 1 ħ, the model became viable  Soon, neutrons were used to naturally explain spin differences in many different nuclides in the same way 
If the proton–neutron model for the nucleus resolved many issues, it highlighted the problem of explaining the origins of beta radiation  No existing theory could account for how electrons, or positrons, could emanate from the nucleus  In 1934, Enrico Fermi published his classic paper describing the process of beta decay, in which the neutron decays to a proton by creating an electron and a (as yet undiscovered) neutrino  The paper employed the analogy that photons, or electromagnetic radiation, were similarly created and destroyed in atomic processes  Ivanenko had suggested a similar analogy in 1932  Fermi's theory requires the neutron to be a spin-1⁄2 particle  The theory preserved the principle of conservation of energy, which had been thrown into question by the continuous energy distribution of beta particles  The basic theory for beta decay proposed by Fermi was the first to show how particles could be created and destroyed  It established a general, basic theory for the interaction of particles by weak or strong forces  While this influential paper has stood the test of time, the ideas within it were so new that when it was first submitted to the journal Nature in 1933 it was rejected as being too speculative 

The nature of the neutron
The question of whether the neutron was a composite particle of a proton and an electron persisted for a few years after its discovery  In 1932 Harrie Massey explored a model for a composite neutron to account for its great penetrating power through matter and its electrical neutrality, for example  The issue was a legacy of the prevailing view from the 1920s that the only elementary particles were the proton and electron 
The nature of the neutron was a primary topic of discussion at the 7th Solvay Conference held in October 1933, attended by Heisenberg, Niels Bohr, Lise Meitner, Ernest Lawrence, Fermi, Chadwick, and others  As posed by Chadwick in his Bakerian Lecture in 1933, the primary question was the mass of the neutron relative to the proton  If the neutron's mass was less than the combined masses of a proton and an electron (1 0078 u), then the neutron could be a proton-electron composite because of the mass defect from the nuclear binding energy  If greater than the combined masses, then the neutron was elementary like the proton  The question was challenging to answer because the electron's mass is only 0 05% of the proton's, hence exceptionally precise measurements were required 
The difficulty of making the measurement is illustrated by the wide-ranging values for the mass of the neutron obtained from 1932 to 1934  The accepted value today is 1 00866 u  In Chadwick's 1932 paper reporting on the discovery, he estimated the mass of the neutron to be between 1 005 u and 1 008 u  By bombarding boron with alpha particles, Frédéric and Irène Joliot-Curie obtained a high value of 1 012 u, while Ernest Lawrence's team at the University of California measured the small value 1 0006 u using their new cyclotron In 1935 Chadwick and his doctoral student Maurice Goldhaber resolved the issue by reporting the first accurate measurement of the mass of the neutron  They used the 2 6 MeV gamma rays of Thallium-208 (208Tl) (then known as thorium C") to photodisintegrate the deuteron 
In this reaction, the resulting proton and neutron have about equal kinetic energy, since their masses are about equal   The kinetic energy of the resulting proton could be measured (0 24 MeV), and therefore the deuteron's binding energy could be determined (2 6 MeV − 2(0 24 MeV) = 2 1 MeV, or 0 0023 u)  The neutron's mass could then be determined by the simple mass balance

where md,p,n refer to the deuteron, proton, or neutron mass, and "b e " is the binding energy  The masses of the deuteron and proton were known; Chadwick and Goldhaber used values 2 0142 u and 1 0081 u, respectively   They found that the neutron's mass was slightly greater than the mass of the proton 1 0084 u or 1 0090 u, depending on the precise value used for the deuteron mass  The mass of the neutron was too large to be a proton–electron composite, and the neutron was therefore identified as an elementary particle   Chadwick and Goldhaber predicted that a free neutron would be able to decay into a proton, electron, and neutrino (beta decay) 

Neutron physics in the 1930s
Soon after the discovery of the neutron, indirect evidence suggested the neutron had an unexpected non-zero value for its magnetic moment  Attempts to measure the neutron's magnetic moment originated with the discovery by Otto Stern in 1933 in Hamburg that the proton had an anomalously large magnetic moment  By 1934 groups led by Stern, now in Pittsburgh, and I  I  Rabi in New York had independently deduced that the magnetic moment of the neutron was negative and unexpectedly large by measuring the magnetic moments of the proton and deuteron  Values for the magnetic moment of the neutron were also determined by Robert Bacher (1933) at Ann Arbor and I Y  Tamm and S A  Altshuler (1934) in the Soviet Union from studies of the hyperfine structure of atomic spectra  By the late 1930s accurate values for the magnetic moment of the neutron had been deduced by the Rabi group using measurements employing newly developed nuclear magnetic resonance techniques  The large value for the proton's magnetic moment and the inferred negative value for the neutron's magnetic moment were unexpected and raised many questions 

The discovery of the neutron immediately gave scientists a new tool for probing the properties of atomic nuclei  Alpha particles had been used over the previous decades in scattering experiments, but such particles, which are helium nuclei, have +2 charge  This charge makes it difficult for alpha particles to overcome the Coulomb repulsive force and interact directly with the nuclei of atoms  Since neutrons have no electric charge, they do not have to overcome this force to interact with nuclei  Almost coincident with their discovery, neutrons were used by Norman Feather, Chadwick's colleague and protege, in scattering experiments with nitrogen  Feather was able to show that neutrons interacting with nitrogen nuclei scattered to protons or induced nitrogen to disintegrate to form boron with the emission of an alpha particle  Feather was therefore the first to show that neutrons produce nuclear disintegrations 
In Rome, Enrico Fermi and his team bombarded heavier elements with neutrons and found the products to be radioactive  By 1934 they had used neutrons to induce radioactivity in 22 different elements, many of these elements of high atomic number  Noticing that other experiments with neutrons at his laboratory seemed to work better on a wooden table than a marble table, Fermi suspected that the protons of the wood were slowing the neutrons and so increasing the chance for the neutron to interact with nuclei  Fermi therefore passed neutrons through paraffin wax to slow them and found that the radioactivity of some bombarded elements increased by a factor of tens to hundreds  The cross section for interaction with nuclei is much larger for slow neutrons than for fast neutrons  In 1938 Fermi received the Nobel Prize in Physics "for his demonstrations of the existence of new radioactive elements produced by neutron irradiation, and for his related discovery of nuclear reactions brought about by slow neutrons" 

In Berlin, the collaboration of Lise Meitner and Otto Hahn, together with their assistant Fritz Strassmann, furthered the research begun by Fermi and his team when they bombarded uranium with neutrons  Between 1934 and 1938, Hahn, Meitner, and Strassmann found a great number of radioactive transmutation products from these experiments, all of which they regarded as transuranic  Transuranic nuclides are those that have an atomic number greater than uranium (92), formed by neutron absorption; such nuclides are not naturally occurring  In July 1938, Meitner was forced to escape antisemitic persecution in Nazi Germany after the Anschluss, and she was able to secure a new position in Sweden  The decisive experiment on 16–17 December 1938 (using a chemical process called "radium–barium–mesothorium fractionation") produced puzzling results: what they had understood to be three isotopes of radium were instead consistently behaving as barium  Radium (atomic number 88) and barium (atomic number 56) are in the same chemical group   By January 1939 Hahn had concluded that what they had thought were transuranic nuclides were instead much lighter nuclides, such as barium, lanthanum, cerium and light platinoids  Meitner and her nephew Otto Frisch immediately and correctly interpreted these observations as resulting from nuclear fission, a term coined by Frisch Hahn and his collaborators had detected the splitting of uranium nuclei, made unstable by neutron absorption, into lighter elements  Meitner and Frisch also showed that the fission of each uranium atom would release about 200 MeV of energy  The discovery of fission electrified the global community of atomic physicists and the public   In their second publication on nuclear fission, Hahn and Strassmann predicted the existence and liberation of additional neutrons during the fission process  Frédéric Joliot and his team proved this phenomenon to be a chain reaction in March 1939  In 1945 Hahn received the 1944 Nobel Prize in Chemistry "for his discovery of the fission of heavy atomic nuclei "

After 1939
The discovery of nuclear fission at the end of 1938 marked a shift in the centers of nuclear research from Europe to the United States  Large numbers of scientists were migrating to the United States to escape the troubles and antisemitism in Europe and the looming war: 407–410  (See Jewish scientists and the Manhattan Project)  The new centers of nuclear research were the universities in the United States, particularly Columbia University in New York and the University of Chicago where Enrico Fermi had relocated, and a secret research facility at Los Alamos, New Mexico, established in 1942, the new home of the Manhattan project  This wartime project was focussed on the construction of nuclear weapons, exploiting the enormous energy released by the fission of uranium or plutonium through neutron-based chain reactions 
The discoveries of the neutron and positron in 1932 were the start of the discoveries of many new particles   Muons were discovered in 1936   Pions and kaons were discovered in 1947, while lambda particles were discovered in 1950   Throughout the 1950s and 1960s, a large number of particles called hadrons were discovered   A classification scheme for organizing all these particles, proposed independently by Murray Gell-Mann and
George Zweig in 1964, became known as the quark model  By this model, particles such as the proton and neutron were not elementary, but composed of various configurations of a small number of other truly elementary particles called partons or quarks  The quark model received experimental verification beginning in the late 1960s and finally provided an explanation for the neutron's anomalous magnetic moment

"Fire and Rain" is a song written and performed by American singer-songwriter James Taylor, released in August 1970 by Warner Bros  Records as the second single from Taylor's second studio album, Sweet Baby James  The song follows Taylor's reaction to the suicide of Suzanne Schnerr, a childhood friend, and his experiences with drug addiction and fame  After its release, "Fire and Rain" peaked at number two on RPM's Canada Top Singles chart and at number three on the Billboard Hot 100 

Background and composition
On the VH1 series Storytellers, Taylor said the song was about several incidents during his early recording career   The second line "Suzanne, the plans they made put an end to you" refers to Suzanne Schnerr, a childhood friend of his who died by suicide while he was in London, England, recording his first album  In that same account, Taylor said he had been in a deep depression after the failure of his new band the Flying Machine to coalesce (the lyric "Sweet dreams and Flying Machines in pieces on the ground"; the reference is to the name of the band rather than a fatal plane crash, as was long rumored)  Taylor completed writing the song while in rehab In 2005, during an interview on NPR, Taylor explained to host Scott Simon that the song was written in three parts:
The first part was about Taylor's friend Suzanne, who died while Taylor was in London working on his first album after being signed to Apple Records  Friends at home, concerned that it might distract Taylor from his big break, kept the tragic news from him, and he found out six months later 
The second part details Taylor's struggle to overcome drug addiction and depression 
The third part deals with coming to grips with fame and fortune, looking back at the road that got him there  It includes a reference to James Taylor and the Flying Machine, a band he briefly worked with before his big break with Paul McCartney, Peter Asher, and Apple Records Carole King played piano on the song  Drummer Russ Kunkel used brushes rather than sticks on his drum kit, and Bobby West played double bass in place of a bass guitar to "underscore the melancholy on the song" 

Reception
Record World said that the release of Taylor's version as a single after several cover versions had been released "was bound to come along  With so many versions out there is no reason the excellent original will not be THE one " Cash Box similarly referred to Taylor releasing it as a single saying "Now, the fourth or fifth to release his own 'Fire & Rain,' Taylor may have found his sought after single hit the hard way  The 'original' comes in the wake of R  B  Greaves' sales and Johnny Rivers' current treatment (not to mention BS&T's album track getting further notice) "  Billboard described it as a "poignant ballad "Broadcast Music, Inc  ranked "Fire and Rain" at number 82 on its "Top 100 Songs of the Century" list, while voters for the National Endowment for the Arts and Recording Industry Association of America's Songs of the Century list, which comprises 365 songs of "historical significance" recorded from 1900 to 2000, placed "Fire and Rain" at number 85  In April 2011, the song was named at number 227 on Rolling Stone's list of 500 greatest songs of all time

Cover versions
R  B  Greaves and Johnny Rivers first released singles of "Fire and Rain" in 1970  Warner Brothers released Taylor's original as a single later that year, in August 1970  Greaves' and Rivers' versions peaked at numbers 82 and 94 on the Billboard Hot 100, respectively Billboard predicted that Greaves' version would be a hit and said that "The James Taylor song is a natural and the production matches the song in merit "  Record World also predicted it to be a hit and said that Taylor and Greaves "are perfect together "Record World called Rivers' version "top quality stuff " Cash Box said of Rivers' version that "the tang of country pop and a top forty arrangement make this the most commercial single yet on 'Fire & Rain '"American singer-songwriter Tim Hardin (cited by James Taylor as a songwriting influence) included a "heartwrenchingly moving" rendition of "Fire and Rain" on his 1973 album Nine 
Marcia Hines covered "Fire and Rain" on her 1975 debut LP, Marcia Shines   Her version reached No  17 in Australia  At the 1975 Australian Record Awards, the song won Hines Female Vocal Single of the Year 

References in other works
Taylor references the song in another of his compositions, "That's Why I'm Here", title track from his 1985 album, in which he writes, "Fortune and fame's such a curious game  Perfect strangers can call you by name  Pay good money to hear 'Fire and Rain' again and again and again "
He also refers to the song in another composition, "Money Machine" (a cynical take on the financial aspects of the recording industry): "When I began the game, see me singing ‘bout Fire and Rain; Lemme just sing it again — I've seen fives and I’ve seen tens "
Carole King has stated that her song "You've Got a Friend", which Taylor recorded, was a response to the line in the refrain, "I've seen lonely times when I could not find a friend "

Parodies
Taylor performs the song on The Simpsons in the episode "Deep Space Homer"  While singing the song for a group of astronauts (including Homer Simpson and Buzz Aldrin), he changes the lyric "Sweet dreams and flying machines in pieces on the ground" to "Sweet dreams and flying machines, flying safely through the air" when he realizes the Space Shuttle may crash In 2015, Taylor appeared on The Late Show with Stephen Colbert, where he sang a version including numerous references to post-1970 popular culture

Question: What was the person who provided evidence to suggest the existence of the neutron a participant of?

The following are given passages.
Context 4:  The original score and songs were composed and conducted by James Horner 
The album garnered nominations for the Golden Globe Award for Best Original Score and the Academy Award for Best Original Score  Music critics felt that the musical score fit the film well, but believed it to be similar to several of Horner's previous films 

Development
Composer James Horner was a frequent collaborator with Ron Howard, the director of A Beautiful Mind  Horner desired to feature vocals reminiscent of being midway between a girl and woman, and wrote the score specifically for 15-year-old Welsh singer Charlotte Church  To convey "the beauty of mathematics", Horner decided to use the idea of a kaleidoscope, as its "patterns are always changing, and things move very quickly, but in moving so quickly, they create other patterns that move very slowly underneath"  He added that these changing patterns were conveyed with the piano and Church's voice 

Release and reception
Writing for Empire magazine, Danny Graydon gave the soundtrack four out of five stars  He thought the score contained elements of Horner's previous films Sneakers (1992) and Bicentennial Man (1999), but said "if you can forgive that, this is a clever, masterful and romantic score that captures a brilliant mind in conflict"  In the tracks "Creating Government Dynamics" and "Cracking The Russian Codes", Graydon opined that Church's "poignant vocals mix well with the frenetic piano and strings to represent Nash’s brilliance" and wished that her voice had been used more in the film Dan Goldwasser of Soundtrack net also found similarities to the score in Bicentennial Man, but thought Horner's work fit the film regardless, explaining "it effectively underscores the drama and romance, and even provides a few bits of tension for the action scene"  Goldwasser concluded that "while it all works well in the film, there is enough about this score that just seemed to  [sic] 'familiar' to make it stand out"  Contributing to National Public Radio, Andy Trudeau believed Church's particular voice adds a "human element  It's the sound that, I think, gives a sense of--the center of this character, if you will  I think it's the soul  And it's trying to be normal in a way, and underneath it it's trying to be crazy" Horner's score garnered nominations for the Golden Globe Award for Best Original Score and the Academy Award for Best Original Score  It lost the Golden Globe to the film Moulin Rouge! and the Oscar to The Lord of the Rings: The Fellowship of the Ring
