The authors present preliminary results from a new research project based in Jebel Shaqadud, Sudan. Their findings highlight the potential for this region's archaeological record to expand our understanding of the adaptation strategies used by human groups in arid north-east African environments away from rivers and lakes during the Holocene. Furthermore, they present exceptionally early radiocarbon dates that push postglacial human occupation in the eastern Sahel back to the twelfth millennium BP.

A primary barrier to translation of clinical research discoveries into care delivery and population health is the lack of sustainable infrastructure bringing researchers, policymakers, practitioners, and communities together to reduce silos in knowledge and action. As National Institutes of Healthʼs (NIH) mechanism to advance translational research, Clinical and Translational Science Award (CTSA) awardees are uniquely positioned to bridge this gap. Delivering on this promise requires sustained collaboration and alignment between research institutions and public health and healthcare programs and services. We describe the collaboration of seven CTSA hubs with city, county, and state healthcare and public health organizations striving to realize this vision together. Partnership representatives convened monthly to identify key components, common and unique themes, and barriers in academic–public collaborations. All partnerships aligned the activities of the CTSA programs with the needs of the city/county/state partners, by sharing resources, responding to real-time policy questions and training needs, promoting best practices, and advancing community-engaged research, and dissemination and implementation science to narrow the knowledge-to-practice gap. Barriers included competing priorities, differing timelines, bureaucratic hurdles, and unstable funding. Academic–public health/health system partnerships represent a unique and underutilized model with potential to enhance community and population health.

Psychological factors have long been thought to play a contributing role in either the predisposition, onset or course of various physical illnesses. Recently, rapid advances in immunology have created interest in the interaction between psychosocial factors, behaviour and the immune system. This paper reviews some of the models proposed to explain the relationship between psychological variables and physical illness and presents evidence for a contribution of psychological factors to certain illnesses in which abnormalities in immunologic state are thought to be important. From a somewhat different perspective, animal studies have demonstrated complex effects of stress, on disease susceptibility. Recent human studies have demonstrated consistent immunologic changes in people undergoing acute naturally occurring psychological stress such as bereavement or an important examination. In humans, the effects of chronic stress may be different from acute stress, corresponding to the findings in animals. Abnormalities in immunologic functioning and physical illness are reviewed for different psychiatric disorders — depression, anorexia nervosa and schizophrenia; depression is the only disorder which consistently demonstrated immunologic changes. Possible mechanisms for the stress/immune-change relationship are suggested.

Although political science provides many useful tools for analyzing the effects of natural and social catastrophes such as Hurricane Katrina and its aftermath, the scenes of devastation and inequality in New Orleans suggest an urgent need to adjust our lenses and reorient our research in ways that will help us to uncover and unpack the roots of this national travesty. Treated merely as exceptions to the “normal” functioning of society, dramatic events such as Katrina ought instead to serve as crucial reminders to scholars and the public that the quest for racial equality is only a work in progress. New Orleans, we argue, was not exceptional; it was the product of broader and very typical elements of American democracy—its ideology, attitudes, and institutions. At the dawn of the century after “the century of the color-line,” the hurricane and its aftermath highlight salient features of inequality in the United States that demand broader inquiry and that should be incorporated into the analytic frameworks through which American politics is commonly studied and understood. To this end, we suggest several ways in which the study of racial and other forms of inequality might inform the study of U.S. politics writ large, as well as offer a few ideas about ways in which the study of race might be re-politicized. To bring race back into the study of politics, we argue for greater attention to the ways that race intersects with other forms of inequality, greater attention to political institutions as they embody and reproduce these inequalities, and a return to the study of power, particularly its role in the maintenance of ascriptive hierarchies.
