Who Was Albert Luthuli?

In an excellent addition to the Ohio Short Histories of Africa series, Robert Trent Vinson recovers the important but largely forgotten story of Albert Luthuli, Africa’s first Nobel Peace Prize winner and president of the African National Congress from 1952 to 1967. One of the most respected African leaders, Luthuli linked South African antiapartheid politics with other movements, becoming South Africa’s leading advocate of Mahatma Gandhi’s nonviolent civil disobedience techniques. He also framed apartheid as a crime against humanity and thus linked South African antiapartheid struggles with international human rights campaigns. Unlike previous studies, this book places Luthuli and the South African antiapartheid struggle in new global contexts, and aspects of Luthuli’s leadership that were not previously publicly known: Vinson is the first to use new archival evidence, numerous oral interviews, and personal memoirs to reveal that Luthuli privately supported sabotage as an additional strategy to end apartheid. This multifaceted portrait will be indispensable to students of African history and politics and nonviolence movements worldwide.https://scholarworks.wm.edu/asbookchapters/1132/thumbnail.jp

Introduction to The Americans Are Coming! Dreams of African American Liberation in Segregationist South Africa

For more than half a century before World War II, black South Africans and “American Negroes”—a group that included African Americans and black West Indians—established close institutional and personal relationships that laid the necessary groundwork for the successful South African and American antiapartheid movements. Though African Americans suffered under Jim Crow racial discrimination, oppressed Africans saw African Americans as free people who had risen from slavery to success and were role models and potential liberators. Many African Americans, regarded initially by the South African government as “honorary whites” exempt from segregation, also saw their activities in South Africa as a divinely ordained mission to establish “Africa for Africans,” liberated from European empires. The Jamaican-born Marcus Garvey’s Universal Negro Improvement Association, the largest black-led movement with two million members and supporters in forty-three countries at its height in the early 1920s, was the most anticipated source of liberation. Though these liberation prophecies went unfulfilled, black South Africans continued to view African Americans as inspirational models and as critical partners in the global antiapartheid struggle. The Americans Are Coming! is a rare case study that places African history and American history in a global context and centers Africa in African Diaspora studies.https://scholarworks.wm.edu/asbookchapters/1131/thumbnail.jp

Providential Design: American Negroes and Garveyism in South Africa

Transcending geographic and cultural lines, From Toussaint to Tupac is an ambitious collection of essays exploring black internationalism and its implications for a black consciousness. At its core, black internationalism is a struggle against oppression, whether manifested in slavery, colonialism, or racism. The ten essays in this volume offer a comprehensive overview of the global movements that define black internationalism, from its origins in the colonial period to the present. From Toussaint to Tupac focuses on three moments in global black history: the American and Haitian revolutions, the Garvey movement and the Communist International following World War I, and the Black Power movement of the late twentieth century. Contributors demonstrate how black internationalism emerged and influenced events in particular localities, how participants in the various struggles communicated across natural and man-made boundaries, and how the black international aided resistance on the local level, creating a collective consciousness. In sharp contrast to studies that confine Black Power to particular national locales, this volume demonstrates the global reach and resonance of the movement. The volume concludes with a discussion of hip hop, including its cultural and ideological antecedents in Black Power.https://scholarworks.wm.edu/asbookchapters/1101/thumbnail.jp

Genetic architecture of human obesity traits in the rhesus macaque

Objective: Whereas the metabolic consequences of obesity have been studied extensively in the rhesus macaque, corollary genetic studies of obesity are nonexistent. This study assessed genetic contributions to spontaneous adiposity in this species. Methods: Phenotypic variation by age class and sex for BMI, waist to height ratio, waist to thigh ratio, and waist circumference was assessed in 583 macaques. Total and sex-specific heritability for all traits was estimated, including waist to thigh ratio adjusted for BMI, as well as genotypic and phenotypic correlations. In addition, functional genetic variation at BDNF, FTO, LEP, LEPR, MC4R, PCSK1, POMC, and SIM1 was assessed in four animals with extreme spontaneous adiposity. Results: Trait heritability in the combined sample was low to moderate (0.14-0.32), whereas sex-specific heritability was more substantial (0.20-0.67). Heritability was greater in females for all traits except BMI. All traits were robustly correlated, with genetic correlations of 0.63 to 0.93 indicating substantial pleiotropy. Likely functional variants were discovered in the four macaques at all eight human obesity genes, including six missense mutations in BDNF, FTO, LEP, LEPR, and PCSK1 and, notably, one nonsense mutation in LEPR. Conclusions: A moderate polygenic contribution to adiposity in rhesus macaques was found, as well as mutations with potentially larger effects in multiple genes that influence obesity in humans

Supplementary information accompanies this paper at doi:10.1038/s41598-017-01971-2.The question of how cell division orientation is determined is fundamentally important for understanding tissue and organ shape in both healthy or disease conditions. Here we provide evidence for cell contact-dependent orientation of planar cell division in the mammalian embryonic skin. We propose a model where the core planar polarity proteins Celsr1 and Frizzled-6 (Fz6) communicate the long axis orientation of interphase basal cells to neighbouring basal mitoses so that they align their horizontal division plane along the same axis. The underlying mechanism requires a direct, cell surface, planar polarised cue, which we posit depends upon variant post-translational forms of Celsr1 protein coupled to Fz6. Our hypothesis has parallels with contact-mediated division orientation in early C. elegans embryos suggesting functional conservation between the adhesion-GPCRs Celsr1 and Latrophilin-1. We propose that linking planar cell division plane with interphase neighbour long axis geometry reinforces axial bias in skin spreading around the mouse embryo body.Peer reviewe

Evaluation of a Microbial Inhibitor in Artificial Diets of a Generalist Caterpillar, Heliothis virescens

Controlling microbial growth in artificial diets is a key component in the rearing of laboratory insects. In this study an antimicrobial agent, Diet Antimicrobial Agent (DAA), was tested for its ability to suppress microbial growth on a range of different diets, and for its effect on larval and pupal performance of individuals from two different strains of Heliothis virescens Fabricus (Lepidoptera: Noctuidae). In the first experiment, it was found that the presence of DAA in a pinto bean-based diet was highly effective at suppressing microbial growth relative to other methods, and that survival of caterpillars on diets with DAA was superior to other treatments. Caterpillars also performed best on diets with DAA, although this may have been the result of laboratory selection pressure as these caterpillars had been reared on pinto bean-based diets with DAA for several hundred generations. A second experiment was conducted, using different diets and a different strain of H. virescens to more fully evaluate DAA. Here it was found that DAA significantly suppressed microbial growth and development, particularly in synthetic diets. There was no significant effect of DAA on pupal development time or mass gain. There was a statistically significant effect of DAA on eclosion time for two of the diets, although the effect did not seem to be biologically meaningful. The findings suggest that DAA is an effective suppressor of microbial growth on artificial diets, and that its net effect on developing diet-reared insects is neutral
