A sociological economy of HIV/AIDS vaccine partnerships: case studies from Africa and India

Public–private partnerships (PPPs) are perhaps the key emergent theme in the delivery of what the socio-economic literature terms global public goods. In light of the problems relating to the distribution of health services and products in developing countries, partnerships between public and private institutions are often proposed as an innovative mechanism to reconnect and reorient supply and demand. In this area, the International Aids Vaccine Initiative (IAVI), which is driving the development of candidate HIV/AIDS vaccines through injections of capital into the research process, represents a significant case study. IAVI seeks to form partnerships between key public and private interests committing them to sharing the risks, costs and benefits of research into an effective and affordable vaccine against HIV. Our empirical work covers partnerships based in several countries including Kenya, Uganda, Rwanda and India. Our early findings highlight IAVI's ability as a learning institution as it adapts its institutional arrangements to various local contexts. An offshoot of this appears to be the building of real local capacity.     

On the Importance of Comparative Research for the Understanding of Human Behavior and Development: A Reply to Gottlieb & Lickliter (2004)

Comparative behavioral research is important for a number of reasons and can contribute to the understanding of human behavior and development in many different ways. Research with animal models of human behavior and development can be a source not only of general principles and testable hypotheses but also of empirical information that may be extrapolated to humans.

Cognitive therapy and behavioural coping in the management of work-related stress: An intervention study

Transactional models of stress emphasize the importance of cognitive appraisal of potential stressors in the determination of the stress response. This appraisal can be modified by the use of techniques normally associated with cognitive therapy. The contribution of a specifically cognitive component when intervening in work-related stress has not been well evaluated to date. This research seeks to determine the effectiveness of stress management training in the treatment of the work-related effects of stress by comparing the role of modifying dysfunctional cognitions with the teaching of appropriate behavioural coping strategies. Participants were allocated to one of two intervention conditions or to a waiting list control group. Those in the intervention conditions received group stress management either with the focus on delivering cognitive therapy techniques or with the focus on behavioural coping skills. Measures of general health were taken at the beginning and end of intervention and at 3-month follow-up. Participants in the cognitive therapy groups who were reporting symptoms of general ill-health at the start of the intervention showed a significant improvement at follow-up. Cognitive therapy appears to have been an effective intervention in work-related stress. Those in the behavioural group showed a smaller but still clinically effective improvement. Results are discussed in terms of methodological issues and implications for future research. It is suggested that changes in cognitive appraisal may need to be developed.     

开放经济下人民币汇率制度选择分析

2 0世纪 80年代以来 ,金融全球化趋势日渐明显 ,伴随着资本流动的加快和汇率波动的频繁 ,金融危机时有发生。而历次金融危机都与汇率制度的安排和国际资本流动密切相关 ,这使得汇率制度的选择成为各国政府无法回避的理论和现实问题。中国现行的汇率制度是以市场供求为基础的、单一的、有管理的浮动汇率制 ,其实质是“有管理而无浮动”的固定汇率制 ,面对“入世”后金融业的对外开放和资本项目的逐步放开 ,目前的汇率制度将受到严峻挑战。本文从现行汇率制度的缺陷入手 ,以蒙代尔 -弗莱明模型为理论分析框架 ,着重对人民币汇率的市场化改革提供政策建议     

Maternal Emotional Styles and Child Social Adjustment: Assessment, Correlates, Outcomes and Goodness of Fit in Early Childhood

The goals of the present research were to develop a modified version of an existing self‐assessment questionnaire designed to measure parents’ emotional style and to examine how the aspects of child regulation may moderate the relation between the emotional styles and social outcomes in childhood. Participants in Study 1 were 140 mothers and children (73 males, 67 females, M_age=56.0 months). The mothers completed the Maternal Emotional Styles Questionnaire (MESQ) to assess maternal emotional styles, and the Child Behavior Vignettes to assess parental goals across two scenarios. Participants in Study 2 were 50 mothers who were interviewed regarding their emotional styles using the Meta‐emotion Interview, and who also completed the MESQ. In Study 3, 100 mothers and children (41 males, 59 females, M=58.0 months) participated. The mothers completed the MESQ and the Child Behavior Questionnaire to assess the children's emotion and behavior regulation. Teachers completed the Child Behavior Scale to measure the indices of preschool adjustment. Results from Studies 1 and 2 indicated a two‐factor scale for the MESQ, with good psychometric properties (including stability, convergent validity, and construct validity). Results from Study 3 indicated different patterns of associations between maternal emotional styles, and child adjustment for well‐regulated versus dysregulated children.
