paragraph_text: In the early 1960s, American computer scientist Paul Baran developed the concept Distributed Adaptive Message Block Switching with the goal to provide a fault - tolerant, efficient routing method for telecommunication messages as part of a research program at the RAND Corporation, funded by the US Department of Defense. This concept contrasted and contradicted then - established principles of pre-allocation of network bandwidth, largely fortified by the development of telecommunications in the Bell System. The new concept found little resonance among network implementers until the independent work of British computer scientist Donald Davies at the National Physical Laboratory (United Kingdom) in 1965. Davies is credited with coining the modern name packet switching and inspiring numerous packet switching networks in the decade following, including the incorporation of the concept in the early ARPANET in the United States.

paragraph_text: Colquhoun's utilitarian approach to the problem – using a cost-benefit argument to obtain support from businesses standing to benefit – allowed him to achieve what Henry and John Fielding failed for their Bow Street detectives. Unlike the stipendiary system at Bow Street, the river police were full-time, salaried officers prohibited from taking private fees. His other contribution was the concept of preventive policing; his police were to act as a highly visible deterrent to crime by their permanent presence on the Thames. Colquhoun's innovations were a critical development leading up to Robert Peel's "new" police three decades later.

paragraph_text: The word "police" was borrowed from French into the English language in the 18th century, but for a long time it applied only to French and continental European police forces. The word, and the concept of police itself, were "disliked as a symbol of foreign oppression" (according to Britannica 1911). Before the 19th century, the first use of the word "police" recorded in government documents in the United Kingdom was the appointment of Commissioners of Police for Scotland in 1714 and the creation of the Marine Police in 1798.

paragraph_text: A neighbourhood police centre (NPC) is a mid-sized police station in Singapore, introduced in 1997 to replace the Singapore Police Force's Neighbourhood Police Post (NPP) system. Based similarly on the concepts of community policing and modelled after the kōban system in Japan, it allows for police officers on the ground to perform more duties, particularly investigative work, which was previously in the hands of division-based officers.

paragraph_text: Maiden Voyage is the fifth album led by jazz musician Herbie Hancock, and was recorded by Rudy Van Gelder on March 17, 1965 for Blue Note Records. It was issued as BLP 4195 and BST 84195. It is a concept album aimed at creating an oceanic atmosphere. Many of the track titles refer to marine biology or the sea, and the musicians develop the concept through their use of space. The album was presented with the Grammy Hall of Fame Award in 1999.

As for cargo traffic, the airport was China's third-busiest and the 19th-busiest worldwide. Baiyun airport was also the third-busiest airport in China in terms of aircraft movements.

paragraph_text: Southern California is home to Los Angeles International Airport, the second-busiest airport in the United States by passenger volume (see World's busiest airports by passenger traffic) and the third by international passenger volume (see Busiest airports in the United States by international passenger traffic); San Diego International Airport the busiest single runway airport in the world; Van Nuys Airport, the world's busiest general aviation airport; major commercial airports at Orange County, Bakersfield, Ontario, Burbank and Long Beach; and numerous smaller commercial and general aviation airports.

paragraph_text: Studies of this kind outside of Europe are even rarer, so it is difficult to make generalizations, but one small-scale study that compared transnational police information and intelligence sharing practices at specific cross-border locations in North America and Europe confirmed that low visibility of police information and intelligence sharing was a common feature (Alain, 2001). Intelligence-led policing is now common practice in most advanced countries (Ratcliffe, 2007) and it is likely that police intelligence sharing and information exchange has a common morphology around the world (Ratcliffe, 2007). James Sheptycki has analyzed the effects of the new information technologies on the organization of policing-intelligence and suggests that a number of 'organizational pathologies' have arisen that make the functioning of security-intelligence processes in transnational policing deeply problematic. He argues that transnational police information circuits help to "compose the panic scenes of the security-control society". The paradoxical effect is that, the harder policing agencies work to produce security, the greater are feelings of insecurity.

paragraph_text: In psychology, fluid and crystallized intelligence (respectively abbreviated Gf and Gc) are factors of general intelligence, originally identified by Raymond Cattell. Concepts of fluid and crystallized intelligence were further developed by Cattell's student John L. Horn.

paragraph_text: The architecture of different parts of Asia developed along different lines from that of Europe; Buddhist, Hindu and Sikh architecture each having different characteristics. Buddhist architecture, in particular, showed great regional diversity. Hindu temple architecture, which developed around the 3rd century BCE, is governed by concepts laid down in the Shastras, and is concerned with expressing the macrocosm and the microcosm. In many Asian countries, pantheistic religion led to architectural forms that were designed specifically to enhance the natural landscape.

paragraph_text: Fluid and crystallized intelligence were originally identified by Raymond Cattell. Concepts of fluid and crystallized intelligence were further developed by Cattell's student, John L. Horn. Since Cattell's and Horn's publications, the concepts of fluid and crystallized intelligence have become so ingrained in the field of intelligence that they are no longer routinely attributed to Cattell or Horn -- much as Cattell's scree plot became ingrained in the practice of factor analysis or Freud's concept of the subconscious is ingrained in psychology and in the public's perceptions of the mind.

paragraph_text: Early development of intelligence - led policing took place in the UK. It was perceived that police were spending too much time responding to specific incidents, and not tackling the problem of repeat offenders. Therefore, reports by the Audit Commission in 1993 and Her Majesty's Inspectorate of Constabulary in 1997 advocated increased use of intelligence, surveillance and informants to target recidivist offenders, so that police could be more effective in fighting crime. The call was quickly taken up by some police forces, particularly the Kent Constabulary. Intelligence led policing was not a major proponent of policing styles until the September 11th terrorist attacks. Prior to these attacks the majority of all branches of the government would often not divulge any information to each other. The main assumptions of this theory can be described by Ratcliffe's 3i format. As shown by the figure below, the three I's call for close cooperation between police chiefs and intelligence analysts in order to facilitate a strategy that will impact the criminal environment.

paragraph_text: Alan Mathison Turing OBE FRS (/ ˈtjʊərɪŋ /; 23 June 1912 -- 7 June 1954) was an English computer scientist, mathematician, logician, cryptanalyst, philosopher, and theoretical biologist. Turing was highly influential in the development of theoretical computer science, providing a formalisation of the concepts of algorithm and computation with the Turing machine, which can be considered a model of a general purpose computer. Turing is widely considered to be the father of theoretical computer science and artificial intelligence.
