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

Access to health services and health outcomes are generally poorer in rural and remote areas relative to metropolitan areas. In order to improve access to services, many new programs and models of service delivery have been trialled since the first National Rural Health Strategy in 1994. Inadequate evaluation of these initiatives has resulted in failure to garner knowledge, which would facilitate the establishment of evidence-based service models, sustain and systematise them over time and facilitate transfer of successful programs. This is the first study to systematically review the available published literature describing innovative models of comprehensive primary health care (PHC) in rural and remote Australia since the development of the first National Rural Health Strategy (1993–2006). The study aimed to describe what health service models were reported to work, where they worked and why. Methods A reference group of experts in rural health assisted in the development and implementation of the study. Peer-reviewed publications were identified from the relevant electronic databases. 'Grey' literature was identified pragmatically from works known to the researchers, reference lists and from relevant websites. Data were extracted and synthesised from papers meeting inclusion criteria. Results A total of 5391 abstracts were reviewed. Data were extracted finally from 76 'rural' and 17 'remote' papers. Synthesis of extracted data resulted in a typology of models with five broad groupings: discrete services, integrated services, comprehensive PHC, outreach models and virtual outreach models. Different model types assume prominence with increasing remoteness and decreasing population density. Whilst different models suit different locations, a number of 'environmental enablers' and 'essential service requirements' are common across all model types. Conclusion Synthesised data suggest that, moving away from Australian coastal population centres, sustainable models are able to address diseconomies of scale which result from large distances and small dispersed populations. Based on the service requirements and enablers derived from analysis of reported successful PHC service models, we have developed a conceptual framework that is particularly useful in underpinning the development of sustainable PHC models in rural and remote communities

Multiorgan MRI findings after hospitalisation with COVID-19 in the UK (C-MORE): a prospective, multicentre, observational cohort study

Introduction: The multiorgan impact of moderate to severe coronavirus infections in the post-acute phase is still poorly understood. We aimed to evaluate the excess burden of multiorgan abnormalities after hospitalisation with COVID-19, evaluate their determinants, and explore associations with patient-related outcome measures. Methods: In a prospective, UK-wide, multicentre MRI follow-up study (C-MORE), adults (aged ≥18 years) discharged from hospital following COVID-19 who were included in Tier 2 of the Post-hospitalisation COVID-19 study (PHOSP-COVID) and contemporary controls with no evidence of previous COVID-19 (SARS-CoV-2 nucleocapsid antibody negative) underwent multiorgan MRI (lungs, heart, brain, liver, and kidneys) with quantitative and qualitative assessment of images and clinical adjudication when relevant. Individuals with end-stage renal failure or contraindications to MRI were excluded. Participants also underwent detailed recording of symptoms, and physiological and biochemical tests. The primary outcome was the excess burden of multiorgan abnormalities (two or more organs) relative to controls, with further adjustments for potential confounders. The C-MORE study is ongoing and is registered with ClinicalTrials.gov, NCT04510025. Findings: Of 2710 participants in Tier 2 of PHOSP-COVID, 531 were recruited across 13 UK-wide C-MORE sites. After exclusions, 259 C-MORE patients (mean age 57 years [SD 12]; 158 [61%] male and 101 [39%] female) who were discharged from hospital with PCR-confirmed or clinically diagnosed COVID-19 between March 1, 2020, and Nov 1, 2021, and 52 non-COVID-19 controls from the community (mean age 49 years [SD 14]; 30 [58%] male and 22 [42%] female) were included in the analysis. Patients were assessed at a median of 5·0 months (IQR 4·2–6·3) after hospital discharge. Compared with non-COVID-19 controls, patients were older, living with more obesity, and had more comorbidities. Multiorgan abnormalities on MRI were more frequent in patients than in controls (157 [61%] of 259 vs 14 [27%] of 52; p<0·0001) and independently associated with COVID-19 status (odds ratio [OR] 2·9 [95% CI 1·5–5·8]; padjusted=0·0023) after adjusting for relevant confounders. Compared with controls, patients were more likely to have MRI evidence of lung abnormalities (p=0·0001; parenchymal abnormalities), brain abnormalities (p<0·0001; more white matter hyperintensities and regional brain volume reduction), and kidney abnormalities (p=0·014; lower medullary T1 and loss of corticomedullary differentiation), whereas cardiac and liver MRI abnormalities were similar between patients and controls. Patients with multiorgan abnormalities were older (difference in mean age 7 years [95% CI 4–10]; mean age of 59·8 years [SD 11·7] with multiorgan abnormalities vs mean age of 52·8 years [11·9] without multiorgan abnormalities; p<0·0001), more likely to have three or more comorbidities (OR 2·47 [1·32–4·82]; padjusted=0·0059), and more likely to have a more severe acute infection (acute CRP >5mg/L, OR 3·55 [1·23–11·88]; padjusted=0·025) than those without multiorgan abnormalities. Presence of lung MRI abnormalities was associated with a two-fold higher risk of chest tightness, and multiorgan MRI abnormalities were associated with severe and very severe persistent physical and mental health impairment (PHOSP-COVID symptom clusters) after hospitalisation. Interpretation: After hospitalisation for COVID-19, people are at risk of multiorgan abnormalities in the medium term. Our findings emphasise the need for proactive multidisciplinary care pathways, with the potential for imaging to guide surveillance frequency and therapeutic stratification

Airborne interactions between undamaged plants of different cultivars affect insect herbivores and natural enemies

This study investigated the effects of airborne interaction between different barley cultivars on the behaviour of bird cherry-oat aphid Rhopalosiphum padi, the ladybird Coccinella septempunctata and the parasitoid Aphidius colemani. In certain cultivar combinations, exposure of one cultivar to air passed over a different cultivar caused barley to have reduced aphid acceptance and increased attraction of ladybirds and parasitoids. Parasitoids attacked aphids that had developed on plants under exposure more often than those from unexposed plants, leading to a higher parasitisation rate. Ladybirds, but not parasitoids, were more attracted to combined odours from certain barley cultivars than either cultivar alone. The results show that airborne interactions between undamaged plants can affect higher trophic levels, and that odour differences between different genotypes of the same plant species may be sufficient to affect natural enemy behaviour

Dissociable dopamine dynamics for learning and motivation.

The dopamine projection from ventral tegmental area (VTA) to nucleus accumbens (NAc) is critical for motivation to work for rewards and reward-driven learning. How dopamine supports both functions is unclear. Dopamine cell spiking can encode prediction errors, which are vital learning signals in computational theories of adaptive behaviour. By contrast, dopamine release ramps up as animals approach rewards, mirroring reward expectation. This mismatch might reflect differences in behavioural tasks, slower changes in dopamine cell spiking or spike-independent modulation of dopamine release. Here we compare spiking of identified VTA dopamine cells with NAc dopamine release in the same decision-making task. Cues that indicate an upcoming reward increased both spiking and release. However, NAc core dopamine release also covaried with dynamically evolving reward expectations, without corresponding changes in VTA dopamine cell spiking. Our results suggest a fundamental difference in how dopamine release is regulated to achieve distinct functions: broadcast burst signals promote learning, whereas local control drives motivation
