Intensifying Multicultural Education Through Critical Pedagogy, Antiracism, and the Need to Unschool
Authors: Petrovic John E. , Caddell April
Published: November 2020

Multicultural education was born of racial and ethnic minority groups’ struggles to have their experiences, cultures, and ways of life recognized in dominant institutions. In schools, it means teaching the cultures, histories, values, and perspectives of different cultural groups, especially those of historically marginalized peoples. Since this approach can take perniciously shallow forms, educators have sought to incorporate the ideals of critical pedagogy and antiracism to inform a practice of “critical multicultural education.”

Critical pedagogy rejects claims that knowledge is politically neutral and posits education and teaching as political acts. Informed by critical theory, critical pedagogy seeks to awaken students to the social, cultural, political, and economic milieu in which dominant forms of knowledge are constructed and through which power functions. A goal of critical pedagogy is for students to understand the way that injustice manifests and is reproduced and, ideally, to engage in praxis—critical reflection and action—toward societal transformation.

Antiracist scholarship has sought to switch discussion of race and racism away from minority groups and, instead, to analyze white racism and whiteness as integral features of dominant institutions. It connects to critical theory in several ways, foremost of which is the position that racism was born of capitalist social relations. Like critical pedagogy, antiracist education seeks to understand, reveal, and counter structural forms of oppression. As such, antiracist education can be more widely presented as anti-Xist education, that is, antisexist, antiableist, antiheterosexist, and so on. In other words, the importance of antiracist education, as informed by critical race theory, lies not only in centering issues of race and racism. Black feminist scholars, for example, also point to the concern of the “intersectionality” of race, class, gender, and other sites of oppression.

Lastly, unschooling also links to critical theory to the extent that traditional schooling represents and promotes the opposite of freedom and critical self-reflection. From a Marxian standpoint, unschooling understands the material reality of schools as manipulative, not convivial, and as reproductive of the status quo, not transformational. Compulsory, competitive schooling, according to this view, undermines learning and, instead, focuses on production, consumption, and spectation. Unschooling, instead, puts the power, responsibility, and, importantly, freedom for learning in the hands of the learner.

Born of and informed by a number of different social movements (civil rights movements; women’s liberation, gay, and lesbian rights movements; indigenous rights movements; etc.), critical multicultural education, then, stands as multiculturalism plus both collective and individual empowerment for responsible, critical engagement against structural forms of oppression.
Global School Funding Debates and Reforms
Authors: Di Gregorio Elisa , Savage Glenn C.
Published: November 2020

In recent decades, important changes have taken place in terms of how governments debate, manage, and allocate funding for schools. These changes have been strongly influenced by a diversification of actors contributing to the school funding. For example, although governments continue to provide the majority of funding resources for schools across member nations of the Organisation for Economic Co-operation and Development (OECD), many nations have witnessed an increased presence of nongovernment actors, such as philanthropies and corporations, in contributing to the funding of both government and nongovernment schools. Many nations have also seen increases in private parental contributions, which has contributed to the expansion of private schooling relative to traditional public schooling.

Despite significant diversity in funding models across OECD nations, debates about funding are increasingly informed by a transnational field of policy ideas, practices, and evidence. The OECD has been a central force in facilitating this “global conversation” about the complexity of school funding trends and impacts, particularly in relation to the impacts of funding on student achievement and equity. A key question in these evolving debates is whether “more money” alone will improve outcomes or whether the focus needs to shift more toward “what schools do” with money (i.e., a “what works” approach). In response to this question, the OECD has played a leading role in steering global debates away from a historically dominant focus on whether more funding makes a difference or not to student achievement, toward a different narrative that suggests the amount of money only matters up to a certain point, and that what matters most beyond that is what systems and schools do with money. At the same time, the OECD has been central to producing a rearticulated “numbers-driven” understanding of equity, which understands equity primarily in terms of the relationship between a young person’s background and his or her performance on PISA, and which frames equity as primarily important from an economic perspective.

Importantly, however, while schooling funding reforms are increasingly informed by global conversations, policy reforms remain locally negotiated. Recent Australian school funding reforms illustrate this well. Over the past decade, two prominent federal school funding reviews have sought to address funding issues in Australia’s federal system. These reports have been deeply shaped by the distinctive conditions of possibility of Australian federalism, but at the same time have been heavily informed by broader transnational reform narratives and the work of the OECD specifically. Yet while both reviews position the OECD at the center of their respective rationales, each does so in different ways that speak to different policy problems. An exploration of the Australian case and how it relates to broader global conversations about school funding offers important insights into how policies are simultaneously globally and locally negotiated.
Foreign Language Education in Japan
Authors: Kubota Ryuko
Published: November 2020

Historically, foreign language education in Japan has been influenced by local and global conditions. Of the two major purposes of learning a language—to gain new knowledge from overseas and to develop practical communication skills—the latter pragmatic orientation became dominant toward the end the 19th century, when access to foreign language learning increased and English became a dominant language to learn. The trend of learning English as an international language for pragmatic purposes has been further strengthened since the 1980s under the discourses of internationalization and neoliberal globalization. An overview of the current status of foreign language education reveals that there are both formal and non-formal learning opportunities for people of all ages; English predominates as a target language although fewer opportunities to learn other languages exist; English is taught at primary and secondary schools and universities with an emphasis on acquiring communicative skills, although the exam-oriented instructional practices contradict the official goal; and adults learn foreign languages, mainly English, for various reasons, including career advancement and hobbyist enjoyment. Such observations include contestations and contradictions. For instance, there have been debates on whether the major aim of learning English should be pragmatic or intellectual. These debates have taken place against the backdrop of the fact that the learning of a foreign language—de facto English—is much more prevalent in society in the early 21st century compared with previous periods in history, when access to learning opportunities was limited to elites. Another contradiction is between the multilingual reality in local and global communities and the exclusive emphasis on teaching English. This gap can be critically analyzed through a critical realist lens, through which multilayers of ideology in discourses and realities in the material world are examined. The predominance of English is driven by a neoliberal ideology that conceptualizes English as a global language with economic benefit, while testing and shadow education enterprises perpetuate the emphasis on English language teaching. The political economy of foreign language education also explains the longstanding socioeconomic disparity in English ability.
Language Policy and Reform in the Indian School System
Authors: Karthik Rupanjali , Noblit George W.
Published: November 2020

India is a linguistically diverse country and supports this with its Language Policy based on the “Three Language Formula” (every child is taught three languages in school). However, its implementation has exhibited monolingual bias as multiple languages are offered as subjects of study and not as media of instruction. The medium of instruction in the majority of government schools is the concerned state’s regional language. Due to a rise in the demand for English medium instruction, governments in various states have started introducing all English medium instruction in schools.

It is unfortunate that in a multilingual nation, a monolingual mind-set has dominated the language-in-education policies and effective pedagogical reforms have largely remained side-lined in such policy debates. There is no denial of the importance of learning English for the children in government schools in India. However, the success of any language-in-education policy in India will depend on a flexible multilingual approach that recognizes the languages existing in the ecology of children (which will vary from state to state as media of instruction), acknowledges the importance of learning the English language, and ushers in effective pedagogical reforms.
Igbo
Authors: Korieh Chima J.
Published: November 2020

The Igbo-speaking people inhabit most of southeastern Nigeria. Their political economy and culture have been shaped by their long history of habitation in the forest region. Important themes relating to the Igbo past have centered on the question of origin, the agrarian bases of their economy, the decentralized and acephalous structure of their political organization, an achievement-based social system rooted in their traditional humane living, and a fluid gender ideology that recognized male and female roles as complementary rather than oppositional. The Igbo contributed to major historical developments including the development of agriculture, the Bantu migration, and its influence in the making of Bantu cultural areas in sub-Saharan Africa. On the global arena, the Igbo contributed significantly to the transformation of the New World through the Atlantic slave trade and the making of New World cultures. The Igbo made the transition to palm oil production in the postabolition era, thereby contributing to the industrialization of Europe as well as linking their society to the global capitalist economy from the 19th century. The Igbo encounter with Europeans continued through British colonialism, and their struggle to maintain their autonomy would shape British colonialism in Nigeria and beyond. The postcolonial era has been a time of crisis for the Igbo in Nigeria. They were involved in a civil war with Nigeria, known as the Nigeria-Biafra war, and experienced mass killing and genocide but continued to be resilient, drawing from their history and shared experience.
Disease Control and Public Health in Colonial Africa
Authors: Coghe Samuël
Published: November 2020

Disease control and public health have been key aspects of social and political life in sub-Saharan Africa since time immemorial. With variations across space and time, many societies viewed disease as the result of imbalances in persons and societies and combined the use of materia medica from the natural world, spiritual divination, and community healing to redress these imbalances. While early encounters between African and European healing systems were still marked by mutual exchanges and adaptations, the emergence of European germ theory-based biomedicine and the establishment of racialized colonial states in the 19th century increasingly challenged the value of African therapeutic practices for disease control on the continent.

Initially, colonial states focused on preserving the health of European soldiers, administrators, and settlers, who were deemed particularly vulnerable to tropical climate and its diseases. Around 1900, however, they started paying more attention to diseases among Africans, whose health and population growth were now deemed crucial for economic development and the legitimacy of colonial rule. Fueled by new insights and techniques provided by tropical medicine, antisleeping sickness campaigns would be among the first major interventions. After World War I, colonial health services expanded their campaigns against epidemic diseases, but also engaged with broader public health approaches that addressed reproductive problems and the social determinants of both disease and health.

Colonial states were not the only providers of biomedical healthcare in colonial Africa. Missionary societies and private companies had their own health services, with particular logics, methods, and focuses. And after 1945, international organizations such as the World Health Organization (WHO) and the United Nations Children’s Fund (UNICEF) increasingly invested in health campaigns in Africa as well. Moreover, Africans actively participated in colonial disease control, most notably as nurses, midwives, and doctors. Nevertheless, Western biomedicine never gained hegemony in colonial Africa. Many Africans tried to avoid or minimize participation in certain campaigns or continued to utilize the services of local healers and diviners, often in combination with particular biomedical approaches. To what extent colonial disease control impacted on disease incidence and demography is still controversially debated.
Environmental History of the Maghreb, 1800–Present
Authors: Cutler Brock
Published: November 2020

North Africa is a diverse region with a rich history and society, part of a set of varied landscapes that make up a compounded and multiplex socio-ecosystem. Its position as a meeting point—of the desert and the sea, of the Atlantic and the Mediterranean, of North and South, of East and West—makes it a complex and rewarding area of study. This multiplicity of environments and societies means there is no one history of North Africa, it is rather a structure of imbricating stories, no one of which records the whole. The environmental history of the region is no different, as the many different ecosystems—and human relations within them—give rise to different stories and different ways to tell them. Indeed, the strength of the environmental approach to the history of the region is that it allows scholars to introduce important factors into the narrative that are otherwise left out. If history is to capture the richness of past lives, tell a compelling story of people in the world, then it needs to embrace those elements of the world that were important to people. These can be the everyday concerns with watering a garden, the spectacular catastrophes of multiyear drought, or the contemplation of what factors make a place one place and not another.

While there is this bottomless well of potential stories to tell within the environmental history of North Africa, there are some centripetal forces that hold it together. One is the geographical setting, defined by the desert, seas, and Atlas Mountains. Within this setting the relative aridity of the region is its central concern; each history has a place for water within it. The other generalizing trend over the modern period is the increasing centralization of decision-making about the management of that aridity: since 1800, small-scale and localized knowledge, practice, and control over hydrology has been eroded. More and more the local ecosystem has become the regional ecosystem, managed according to a logic shared on a global scale. The tension between these generalized trends and the multiplicity of local ecologies and stories is what gives the environmental history of North Africa its power and appeal.
Menopause
Authors: OlaOlorun Funmilola M. , Shen Wen
Published: November 2020

Menopause is the natural senescence of ovarian hormonal production, and it eventually occurs in every woman. The age at which menopause occurs varies between cultures and ethnicities. Menopause can also be the result of medical or surgical interventions, in which case it can occur at a much younger age. Primary symptoms, as well as attitudes toward menopause, also vary between cultures. Presently, the gold standard for treatment of menopause symptoms is hormone therapy; however, many other options have also been shown to be efficacious, and active research is ongoing to develop better and safer treatments.

In a high-resource setting, the sequelae/physiologic changes associated with menopause can impact a woman’s physical and mental health for the rest of her life. In addition to “hot flashes,” other less well-known conditions include heart disease, osteoporosis, metabolic syndrome, depression, and cognitive decline. In the United States, cardiac disease is the leading cause of mortality in women over the age of 65. The growing understanding of the physiology of menopause is beginning to inform strategies either to prevent or to attenuate these common health conditions. As the baby boomers age, the distribution of age cohorts will increase the burden of disease toward post-reproductive women. In addition to providing appropriate medical care, public health efforts must focus on this population due to the financial impact of this age cohort of women.
The Moon in Meso-America
Authors: Milbrath Susan
Published: November 2020

What is known about the Moon among the ancient Maya of southern Mexico and Guatemala and the Nahuatl-speaking people of central Mexico, especially the Aztecs who lived in the Valley of Mexico and their neighbors in Puebla-Tlaxcala Valley, has been obtained from records related to astronomy and lunar cycles inscribed on Classic Maya monuments dating between ad 250 and 850/900. Modern scholarship focusing on the mathematical units and glyphic writing has helped in deciphering the records. Postclassic Maya codices dating from 1300 to 1500, sent to Europe shortly after the Spanish conquest, also have lunar tables that have been decoded by study of the lunar cycles and glyphs. Painted books dating prior to the conquest in 1521 are also known from central Mexico, but these can only be understood with the help of books that were painted by native artists later in the 16th century and annotated with texts written in Spanish and Nahuatl. These glosses provide information about lunar deities and beliefs about the Moon. Furthermore, knowledge of the Moon in Meso-America is greatly enhanced by ethnographic studies and study of iconographic representations of deities representing different lunar roles and phases.
Order and Justice
Authors: Hurrell Andrew
Published: November 2020

Order and justice are deeply intertwined in English School writing. The central concern of the English School is with the problem of order and with the question: To what extent does the inherited political framework provided by the international society of states continue to provide an adequate basis for world order? This kind of question links closely with the debates on international institutions and global governance that have been so prominent since the end of the Cold War. But the English School focus is less on theoretical understanding of particular institutions and more on assessing the overall character of institutionalization in world politics, the normative commitments inherent in different ways of governing the globe, and the adequacy of historical and existing interstate institutions for meeting practical and normative challenges. There are four specific themes that are central to the pluralist wing of English School writing on order and justice. The first theme concerns power and the conditions of order, while the second concerns diversity and value conflict. Meanwhile, a third theme emerges from the idea that moral values should, so far as possible, be kept out of international life and of particular international institutions. Finally, the fourth theme concerns the argument that international society has the potential not just to help manage international conduct in a restrained way but also to create the conditions for a more legitimate and morally more ambitious political community to emerge. As power diffuses away from the Western, liberal developed core, and as the intractability of the international system to liberal prescriptions becomes more evident, so one can detect new changes in the way in which global justice is understood.
Industrial Workers of the World
Authors: Cole Peter
Published: November 2020

Perhaps the most important radical labor union in U.S. history, the Industrial Workers of the World (IWW) continues to attract workers, in and beyond the United States. The IWW was founded in 1905 in Chicago—at that time, the greatest industrial city in a country that had become the world’s mightiest economy. Due to the nature of industrial capitalism in what, already, had become a global economy, the IWW and its ideals quickly became a worldwide phenomenon. The Wobblies, as members were and still are affectionately known, never were as numerically large as mainstream unions, but their influence, particularly from 1905 into the 1920s, was enormous.

The IWW captured the imaginations of countless rebellious workers with its fiery rhetoric, daring tactics, and commitment to revolutionary industrial unionism. The IWW pledged to replace the “bread and butter” craft unionism of the larger, more mainstream American Federation of Labor (AFL), with massive industrial unions strong enough to take on ever-larger corporations and, ultimately, overthrow capitalism to be replaced with a society based upon people rather than profit. In the United States, the union grew in numbers and reputation, before and during World War I, by organizing workers neglected by other unions—immigrant factory workers in the Northeast and Midwest, migratory farmworkers in the Great Plains, and mine, timber, and harvest workers out West. Unlike most other unions of that era, the IWW welcomed immigrants, women, and people of color; truly, most U.S. institutions excluded African Americans and darker-skinned immigrants as well as women, making the IWW among the most radically inclusive institutions in the country and world.

Wobbly ideas, members, and publications soon spread beyond the United States—first to Mexico and Canada, then into the Caribbean and Latin America, and to Europe, southern Africa, and Australasia in rapid succession. The expansion of the IWW and its ideals across the world in under a decade is a testament to the passionate commitment of its members. It also speaks to the immense popularity of anticapitalist tendencies that shared more in common with anarchism than social democracy. However, the IWW’s revolutionary program and class-war rhetoric yielded more enemies than allies, including governments, which proved devastating during and after World War I, though the union soldiered on. Even in 2020, the ideals the IWW espoused continued to resonate among a small but growing and vibrant group of workers, worldwide.
Uruguay and UN Peacekeeping
Authors: Gonzalez-Guyer Julian
Published: November 2020

During the last quarter of a century, Uruguay has contributed more to UN peacekeeping operations than any other South American nation and was one of the top twenty countries in the ranking of the UN’s Department of Peacekeeping Operations (DPKO) between 2001 and 2016. This is striking when one bears in mind that Uruguay’s population is less than 3.5 million and that the size of its armed forces has been steadily reduced since 1985. With these credentials, Uruguay secured a non-permanent seat on the UN Security Council between 2016 and 2017, a position it had only previously held between 1965 and 1966.

Contributing to peace operations has been a novelty in Uruguay’s foreign policy in the post-dictatorship era, though without breaking with the traditional principles of its foreign policy and strategic identity. Indeed, multilateralism and an adherence to the principles of non-intervention and negotiated conflict resolution have been consistent elements of Uruguayan foreign policy since the beginning of the 20th century. In fact, the motivations for Uruguay’s striking level of commitment to the UN peace operations are mainly linked to the evolution of civil–military relations after the dictatorship of 1973–1985.
The Balaiada War, 1838–1841
Authors: Barreto de Souza Adriana
Published: November 2020

Between 1831 and 1840, the Brazilian Empire was ruled by regents. Pedro I, who became Brazil’s first emperor in 1822 on the occasion of the country’s independence, was forced by a popular political movement to abdicate his throne on April 7, 1831. This episode set off a series of revolts that involved broad segments of society: slaves, Indians, the urban and rural poor, liberal professionals, and large and small landholders.

Not all of the revolts, however, counted such diverse social groups among their ranks, and fewer still included common people in leadership roles. The Balaiada War, or simply the Balaiada, waged in the provinces of Maranhão and Piauí, was one such revolt. Albeit in different phases, this multifaceted movement drew in landholders, slaves, and quilombolas (members of a community formed by escaped African slaves and their descendants, usually in inaccessible regions of the forest or backlands), and was led by caboclos (a term used in northern Brazil to refer to those who work the fields and forests) and a black leader who headed an army of more than 3,000 quilombolas.

These men fought their freedom and civil rights, values widely invoked by the literate elite since the time of Brazil’s independence.

The successful repression (“pacification”) of this movement, beginning in 1840, employed two strategies: by sowing intrigue, it sought to relegate each group to its original place in society and reconstruct social hierarchies; and at a symbolic level, it sought to disparage the war and its leaders, portraying the movement in historical accounts as one of vicious and bloodthirsty barbarians.
Decision-Making in a Water Crisis: Lessons From the Cape Town Drought for Urban Water Policy
Authors: Brühl Johanna , le Roux Leonard , Visser Martine , Köhlin Gunnar
Published: November 2020

The water crisis that gripped Cape Town over the 2016–2018 period gained global attention. For a brief period of time in early 2018, it looked as if the legislative capital of South Africa would become the first major city in the world to run out of water. The case of Cape Town has broad implications for how we think about water management in a rapidly urbanizing world. Cities in the global South, especially, where often under-capacitated urban utilities need to cope with rapid demographic changes, climate change, and numerous competing demands on their tight budgets, can learn from Cape Town’s experience.

The case of Cape Town draws attention to the types of decisions policymakers and water utilities face in times of crisis. It illustrates how these decisions, while being unavoidable in the short term, are often sub-optimal in the long run. The Cape Town drought highlights the importance of infrastructure diversification, better groundwater management, and communication and information transparency to build trust with the public. It also shows what governance and institutional changes need to be made to ensure long-term water security and efficient water management. The implementation of all of these policies needs to address the increased variability of water supplies due to increasingly erratic rainfall and rapidly growing urban populations in many countries. This necessitates a long-term planning horizon.

Published: November 2020

Background

dance is a mind–body activity that stimulates neuroplasticity. We explored the effect of dance on cognitive function in older adults.

Methods

we searched MEDLINE, EMBASE, CENTRAL and PsycInfo databases from inception to August 2020 (PROSPERO:CRD42017057138). Inclusion criteria were (i) randomised controlled trials (ii) older adults (aged ≥ 55 years), (iii) intervention—dance and (iv) outcome—cognitive function. Cognitive domains were classified with the Diagnostic and Statistical Manual of Mental Disorders-5 Neurocognitive Framework. Meta-analyses were performed in RevMan5.3 and certainty of evidence with GradePro.

Results

we reviewed 3,997 records and included 11 studies (N = 1,412 participants). Seven studies included only healthy older adults and four included those with mild cognitive impairment (MCI). Dance interventions varied in frequency (1–3×/week), time (35–60 minutes), duration (3–12 months) and type. We found a mean difference (MD) = 1.58 (95% confidence interval [CI) = 0.21–2.95) on the Mini Mental State Examination for global cognitive function (moderate-certainty evidence), and the Wechsler Memory Test for learning and memory had an MD = 3.02 (95% CI = 1.38–4.65; low-certainty evidence). On the Trail Making Test-A for complex attention, MD = 3.07 (95% CI = −0.81 to 6.95; high-certainty evidence) and on the Trail Making Test-B for executive function, MD = −4.12 (95% CI = −21.28 to 13.03; moderate-certainty evidence). Subgroup analyses did not suggest consistently greater effects in older adults with MCI. Evidence is uncertain for language, and no studies evaluated social cognition or perceptual–motor function.

Conclusions

dance probably improves global cognitive function and executive function. However, there is little difference in complex attention, and evidence also suggests little effect on learning and memory. Future research is needed to determine the optimal dose and if dance results in greater cognitive benefits than other types of physical activity and exercise.
Multiplex PCR and Nanopore Sequencing of Genes Associated with Antimicrobial Resistance in Neisseria gonorrhoeae Directly from Clinical Samples
Authors: Zhang Chi , Xiu Leshan , Li Yamei , Sun Liying , Li Yizhun , Zeng Yaling , Wang Feng , Peng Junping
Published: November 2020

Background

Antimicrobial resistance (AMR) of Neisseria gonorrhoeae has spread worldwide. Rapid and comprehensive methods are needed to describe N. gonorrhoeae AMR profiles accurately. A method based on multiplex amplicon sequencing was developed to simultaneously sequence 13 genes related to AMR in N. gonorrhoeae directly from clinical samples.

Methods

Nine N. gonorrhoeae strains were used for the establishment and validation of the method. Eleven urethral swabs and their corresponding cultured isolates were matched as pairs to determine the accuracy of the method. Mock samples with different dilutions were prepared to determine the sensitivity of the method. Five nongonococcal Neisseria strains and 24 N. gonorrhoeae negative clinical samples were used to evaluate the cross-reactivity. Finally, the method was applied to 64 clinical samples to assess its performance.

Results

Using Sanger sequencing as a reference method, sequences recovered from amplicon sequencing had a base accuracy of over 99.5% and the AMR sites were correctly identified. The limit of detection (LOD) was lower than 31 copies/reaction. No significant cross-reactivity was observed. Furthermore, target genes were successfully recovered from 64 clinical samples including 9 urines, demonstrating this method could be used in different types of samples. For clinical samples, the results can be obtained within a time frame of 7 h 40 min to 10 h 40 min, while for isolates, the turnaround time was approximately 2 h shorter.

Conclusions

This method can serve as a versatile and convenient culture-free diagnostic method with the advantages of high sensitivity and accuracy.
Women’s Earnings are more Affected by Inflammatory Bowel Disease than Men’s: A Register-Based Swedish Cohort Study
Authors: Everhov Åsa H , Bruze Gustaf , Söderling Jonas , Askling Johan , Halfvarson Jonas , Westberg Karin , Malmborg Petter , Nordenvall Caroline , Ludvigsson Jonas F , Olén Ola
Published: November 2020

Background and Aims

Patients with inflammatory bowel disease [IBD] are subject to more work disability than the general population. We aimed to estimate the monetary cost of IBD for the individual through assessment of earnings in relation to diagnosis.

Methods

Through linkage of national registers, we identified patients aged 30–55 years at first IBD diagnosis in Sweden in 2002–2011, and same-sex IBD-free siblings. We estimated taxable earnings and disposable income from 5 years before to 5 years after diagnosis.

Results

The 5961 patients [27% Crohn’s disease, 68% ulcerative colitis, 4.3% IBD unclassified] had similar taxable earnings to their 7810 siblings until the year of diagnosis, when earnings decreased and remained lower than for siblings during follow-up. The adjusted difference in earnings over the entire 5-year period after diagnosis was −5% [−8212€; 95% confidence interval: −11 458 to −4967€]. The difference was greater in women than in men, and greater in Crohn’s disease than in ulcerative colitis. When stratifying for sex and IBD subtype and comparing earnings during each year of follow-up, median annual earnings were lower in women with Crohn’s disease and ulcerative colitis than in their sisters during all years of follow-up, whereas the men had similar annual taxable earnings to their brothers. Disposable income was similar between patients and siblings during the investigated time period.

Conclusion

From the year of diagnosis and at least 5 years onwards, patients with IBD had 5% lower earnings than siblings, mainly explained by differences between women with IBD and their sisters. However, there were no differences in disposable income.
Weeds Impose Unique Outcomes for Pests, Natural Enemies, and Yield in Two Vegetable Crops
Authors: Madden Melina K , Widick Ivy V , Blubaugh Carmen K
Published: November 2020

Weed management requires enormous labor investments from vegetable farmers, yet crops vary in how much weed pressure they can tolerate without yield loss. Moreover, until weeds reach a point where they threaten yield or approach seed production, they can increase biodiversity and provision food and habitat to attract predatory insects. In two related field experiments, we quantified impacts of weed presence and diversity on pests, predators, and biocontrol of both weed seeds and insect prey. We also measured yields of two vegetables that vary in competitiveness (eggplants and turnips) across two weed management treatments (weedy and weed-free), to determine productivity costs of tolerating weeds. Allowing weeds to grow adjacent to rows of eggplants increased abundances of predators and reduced pests. Surprisingly, relaxing weed management came at no cost to eggplant yield. In contrast, tolerating weeds in turnips had strong yield costs, and did not benefit predators or decrease pest pressure. On both crops, pests declined as weed diversity increased. Yet, weed treatments had no impact on consumption of weed seeds or sentinel prey by soil-surface insects, which were dominated by red imported fire ants. Our results suggest that highly competitive crops might benefit from stronger natural pest control when weeds are less-aggressively managed. However, herbivores and predators had unique responses to weeds that were crop-specific. To help farmers allocate limited weed management labor resources, future work should examine the relative competitiveness of a wider variety of vegetables over a gradient of weed pressure while measuring corresponding impacts on pest control.

Aims

Permanent pacemaker implantation (PPI) may be required after transcatheter aortic valve implantation (TAVI). Evidence on PPI prediction has largely been gathered from high-risk patients receiving first-generation valve implants. We undertook a meta-analysis of the existing literature to examine the incidence and predictors of PPI after TAVI according to generation of valve, valve type, and surgical risk.

Methods and results

We made a systematic literature search for studies with ≥100 patients reporting the incidence and adjusted predictors of PPI after TAVI. Subgroup analyses examined these features according to generation of valve, specific valve type, and surgical risk. We obtained data from 43 studies, encompassing 29 113 patients. Permanent pacemaker implantation rates ranged from 6.7% to 39.2% in individual studies with a pooled incidence of 19% (95% CI 16–21). Independent predictors for PPI were age [odds ratio (OR) 1.05, 95% confidence interval (CI) 1.01–1.09], left bundle branch block (LBBB) (OR 1.45, 95% CI 1.12–1.77), right bundle branch block (RBBB) (OR 4.15, 95% CI 3.23–4.88), implantation depth (OR 1.18, 95% CI 1.11–1.26), and self-expanding valve prosthesis (OR 2.99, 95% CI 1.39–4.59). Among subgroups analysed according to valve type, valve generation and surgical risk, independent predictors were RBBB, self-expanding valve type, first-degree atrioventricular block, and implantation depth.

Conclusions

The principle independent predictors for PPI following TAVI are age, RBBB, LBBB, self-expanding valve type, and valve implantation depth. These characteristics should be taken into account in pre-procedural assessment to reduce PPI rates. PROSPERO ID CRD42020164043.
Multi-objective forestry increases the production of ecosystem services

Boreal forests produce multiple ecosystem services for the society. Their trade-offs determine whether they should be produced simultaneously or whether it is preferable to assign separate areas to different ecosystem services. We use simulation and optimization to analyse the correlations, trade-offs and production levels of several ecosystem services in single- and multi-objective forestry over 100 years in a boreal forest landscape. The case study area covers 3600 ha of boreal forest, consisting of 3365 stands. The ecosystem services and their indicators (in parentheses) considered are carbon sequestration (forestry carbon balance), biodiversity (amount of deadwood and broadleaf volume), economic profitability of forestry (net present value of timber production) and timber supply to forest industry (volume of harvested timber). The treatment alternatives simulated for each of the stands include both even-aged rotation forestry (thinning from above with clear cut) and continuous cover forestry regimes (thinning from above with no clear cut). First, we develop 200 Pareto optimal plans by maximizing multi-attribute utility functions using random weights for the ecosystem service indicators. Second, we compare the average level of ecosystem services in single- and multi-objective forestry. Based on our findings, forestry carbon balance and the amount of deadwood correlate positively with each other, and both of them correlate negatively with harvested timber volume and economic profitability of forestry. Despite this, the simultaneous maximization of multiple objectives increased the overall production levels of several ecosystem services, which suggests that the management of boreal forests should be multi-objective to sustain the simultaneous provision of timber and other ecosystem services.
“Am I a Jew?”: Soviet Jewish Youth and Antisemitism on the Home Front during the Second World War
Authors: Belsky Natalie
Published: November 2020

In the wake of the Nazi invasion of June 1941, over one million Soviet Jews were resettled in Central Asia, Siberia, and the Volga and Ural regions for the duration of the war. Prewar antisemitic prejudices and stereotypes, as well as increasingly difficult living conditions, fueled further anti-Jewish sentiment. Children and teenagers were particularly susceptible to harassment because of their frequent contact with local youths at school or in the streets. Often unprepared to deal with these negative attitudes, their responses to and internalization of these early experiences with antisemitism constituted a critical, transformative moment, prompting them to grapple with the meaning of their Jewish identity within the Soviet context.
Constitutionalizing a perpetual transition: The “integration” of the Pashtun “tribal areas” in Pakistan
Authors: Cheema Moeen , Yousaf Farooq
Published: November 2020

This article charts the historical marginalization of Pashtun tribal areas to the periphery of the Pakistani state and undertakes an analysis of the recent movement for their integration in Pakistan’s constitutional structure. It also analyzes contemporaneous developments in Pakistan’s constitutional system, in particular the accommodation of a stronger form of federalism and the emergence of a powerful judiciary brandishing robust judicial review and fundamental rights jurisdictions, which have provided both the backdrop and impetus to the integration of the Federally Administered Tribal Areas (FATA) in Pakistan’s constitutional system of governance. The article asserts that this case study of FATA’s integration demands an acknowledgment of the deeply political and inherently transitional nature of constitutionalism in Pakistan, and arguably many other parts of the Global South.
Consistency, convergence and error estimates for a mixed finite element–finite volume scheme to compressible Navier–Stokes equations with general inflow/outflow boundary data
Authors: Kwon Young-Sam , Novotný Antonín
Published: November 2020

We study convergence of a mixed finite element-finite volume scheme for the compressible Navier–Stokes equations in the isentropic regime under the full range $1<\gamma <\infty $ of the adiabatic coefficients $\gamma $ for the problem with general nonzero inflow–outflow boundary conditions. We propose a modification of Karper’s scheme (2013, A convergent FEM-DG method for the compressible Navier–Stokes equations. Numer. Math.,  125, 441–510) in order to accommodate the nonzero boundary data, prove existence of its solutions, establish the stability and uniform estimates, derive a convenient consistency formulation of the balance laws and use it to show the weak convergence of the numerical solutions to a dissipative solution with the Reynolds defect introduced in Abbatiello et al. (2021, Generalized solutions to models of compressible viscous fluids. Discrete Contin. Dyn. Syst., 41, 1--28). If the target system admits a strong solution then the convergence is strong towards the strong solution. Moreover, we establish the convergence rate of the strong convergence in terms of the size of the space discretization $h$ (which is supposed to be comparable with the time step $\varDelta t$). In the case of the nonzero inflow–outflow boundary data all results are new. The latter result is new also for the no-slip boundary conditions and adiabatic coefficients $\gamma $ less than the threshold $3/2$.
Core-dependent changes in genomic predictions using the Algorithm for Proven and Young in single-step genomic best linear unbiased prediction
Authors: Misztal Ignacy , Tsuruta Shogo , Pocrnic Ivan , Lourenco Daniela
Published: November 2020

Single-step genomic best linear unbiased prediction with the Algorithm for Proven and Young (APY) is a popular method for large-scale genomic evaluations. With the APY algorithm, animals are designated as core or noncore, and the computing resources to create the inverse of the genomic relationship matrix (GRM) are reduced by inverting only a portion of that matrix for core animals. However, using different core sets of the same size causes fluctuations in genomic estimated breeding values (GEBVs) up to one additive standard deviation without affecting prediction accuracy. About 2% of the variation in the GRM is noise. In the recursion formula for APY, the error term modeling the noise is different for every set of core animals, creating changes in breeding values. While average changes are small, and correlations between breeding values estimated with different core animals are close to 1.0, based on the normal distribution theory, outliers can be several times bigger than the average. Tests included commercial datasets from beef and dairy cattle and from pigs. Beyond a certain number of core animals, the prediction accuracy did not improve, but fluctuations decreased with more animals. Fluctuations were much smaller than the possible changes based on prediction error variance. GEBVs change over time even for animals with no new data as genomic relationships ties all the genotyped animals, causing reranking of top animals. In contrast, changes in nongenomic models without new data are small. Also, GEBV can change due to details in the model, such as redefinition of contemporary groups or unknown parent groups. In particular, increasing the fraction of blending of the GRM with a pedigree relationship matrix from 5% to 20% caused changes in GEBV up to 0.45 SD, with a correlation of GEBV > 0.99. Fluctuations in genomic predictions are part of genomic evaluation models and are also present without the APY algorithm when genomic evaluations are computed with updated data. The best approach to reduce the impact of fluctuations in genomic evaluations is to make selection decisions not on individual animals with limited individual accuracy but on groups of animals with high average accuracy.
Insecticide Resistance Development in the Filth Fly Pupal Parasitoid, Spalangia cameroni (Hymenoptera: Pteromalidae), Using Laboratory Selections
Authors: Maiquez Vincent F , Pitzer Jimmy B , Geden Christopher J
Published: November 2020

Filth flies remain one of the most prevalent pest groups affecting the animal production industry. Spalangia spp. and Muscidifurax spp. are beneficial parasitic wasps that often are utilized to manage filth fly populations such as house flies, Musca domestica L. (Diptera: Muscidae), and stable flies, Stomoxys calcitrans (L.) (Diptera: Muscidae). These wasps search for filth fly pupae as hosts in areas potentially treated with insecticides, which may result in nontarget insecticide selection effects. However, research regarding resistance development in parasitic wasps such as S. cameroni Perkins (Hymenoptera: Pteromalidae) is limited. Therefore, a study was conducted to determine the potential of S. cameroni to develop resistance to the commonly used insecticide permethrin, as well as compare permethrin susceptibility among several S. cameroni strains. After 10 selected generations, susceptibility was significantly lower for the selected strain when compared with that of its unselected parent strain. A comparison of several parasitoid strains collected from different U.S. states indicated that permethrin susceptibility was not significantly different between a baseline strain and more recently established field strains. The potential implications of this previously unrecognized nontarget insecticide exposure effect on filth fly parasitoids are discussed.
