Circadian oscillations of cytosolic free calcium regulate the Arabidopsis circadian clock

Abstract: In the last decade, the view of circadian oscillators has expanded from transcriptional feedback to incorporate post-transcriptional, post-translational, metabolic processes and ionic signalling. In plants and animals, there are circadian oscillations in the concentration of cytosolic free Ca2+ ([Ca2+]cyt), though their purpose has not been fully characterized. We investigated whether circadian oscillations of [Ca2+]cyt regulate the circadian oscillator of Arabidopsis thaliana. We report that in Arabidopsis, [Ca2+]cyt circadian oscillations can regulate circadian clock function through the Ca2+-dependent action of CALMODULIN-LIKE24 (CML24). Genetic analyses demonstrate a linkage between CML24 and the circadian oscillator, through pathways involving the circadian oscillator gene TIMING OF CAB2 EXPRESSION1 (TOC1).

Guess who's coming to dinner : Migration from Lesotho, Mozambique and Zimbabwe to South Africa

Abstract: Although a more balanced debate about cross-border migration in South Africa is starting to take place xenophobic stereotypes about migrants of African origin are still all too common. Allusions to a "flood of illegal aliens" who bring disease and crime to the country and who are seen to be a threat to the social and fiscal stability of South Africa are unfortunately still rife in the mainstream press in South Africa. This article is an attempt to challenge some of these stereotypes. Drawing on national surveys recently conducted by the Southern African Migration Project in Lesotho Mozambique and Zimbabwe it will be argued that much of the negative stereotyping around cross-border migration from these three countries in particular in unfounded. A profile of migration histories of those interviewed is followed by a discussion of peoples attitudes towards cross-border movement and immigration policy as well as an analysis of possible future migration trends. The article concludes with a discussion of the policy relevance of the research and makes some general policy recommendations. (authors)

The role of community conversations in facilitating local HIV competence: case study from rural Zimbabwe

Abstract: This paper examines the potential for community conversations to strengthen positive responses to HIV in resource-poor environments. Community conversations are an intervention method through which local people work with a facilitator to collectively identify local strengths and challenges and brainstorm potential strategies for solving local problems. We conducted 18 community conversations (with six groups at three points in time) with a total of 77 participants in rural Zimbabwe (20% HIV positive). Participants were invited to reflect on how they were responding to the challenges of HIV, both as individuals and in community groups, and to think of ways to better support openness about HIV, kindness towards people living with HIV and greater community uptake of HIV prevention and treatment. Community conversations contributed to local HIV competence through (1) enabling participants to brainstorm concrete action plans for responding to HIV, (2) providing a forum to develop a sense of common purpose in relation to implementing these, (3) encouraging and challenging participants to overcome fear, denial and passivity, (4) providing an opportunity for participants to move from seeing themselves as passive recipients of information to active problem solvers, and (5) reducing silence and stigma surrounding HIV. Our discussion cautions that community conversations, while holding great potential to help communities recognize their potential strengths and capacities for responding more effectively to HIV, are not a magic bullet. Poverty, poor harvests and political instability frustrated and limited many participants’ efforts to put their plans into action. On the other hand, support from outside the community, in this case the increasing availability of antiretroviral treatment, played a vital role in enabling communities to challenge stigma and envision new, more positive, ways of responding to the epidemic.

Using a human resource management approach to support community health workers: experiences from five African countries

Abstract: Like any other health worker, community health workers (CHWs) need to be supported to ensure that they are able to contribute effectively to health programmes. Management challenges, similar to those of managing any other health worker, relate to improving attraction, retention and performance. Exploratory case studies of CHW programmes in the Democratic Republic of Congo, Ghana, Senegal, Uganda and Zimbabwe were conducted to provide an understanding of the practices for supporting and managing CHWs from a multi-actor perspective. Document reviews (n = 43), in-depth interviews with programme managers, supervisors and community members involved in managing CHWs (n = 31) and focus group discussions with CHWs (n = 13) were conducted across the five countries. Data were transcribed, translated and analysed using the framework approach. CHWs had many expectations of their role in healthcare, including serving the community, enhancing skills, receiving financial benefits and their role as a CHW fitting in with their other responsibilities. Many human resource management (HRM) practices are employed, but how well they are implemented, the degree to which they meet the expectations of the CHWs and their effects on human resource (HR) outcomes vary across contexts. Front-line supervisors, such as health centre nurses and senior CHWs, play a major role in the management of CHWs and are central to the implementation of HRM practices. On the other hand, community members and programme managers have little involvement with managing the CHWs. This study highlighted that CHW expectations are not always met through HRM practices. This paper calls for a coordinated HRM approach to support CHWs, whereby HRM practices are designed to not only address expectations but also ensure that the CHW programme meets its goals. There is a need to work with all three groups of management actors (front-line supervisors, programme managers and community members) to ensure the use of an effective HRM approach. A larger multi-country study is needed to test an HRM approach that integrates context-appropriate strategies and coordinates relevant management actors. Ensuring that CHWs are adequately supported is vital if CHWs are to fulfil the critical role that they can play in improving the health of their communities.
