Attachment, affect, and sex shape responsivity to psychosocial stress. Concurrent social contexts influence cortisol secretion, a stress hormone and biological marker of hypothalamic–pituitary–adrenal axis activity. Patterns of attachment, emotion status, and sex were hypothesized to relate to bifurcated, that is, accentuated and attenuated, cortisol reactivity. The theoretical framework for this study posits that multiple individual differences mediate a cortisol stress response. The effects of two psychosocial stress interventions, a modified Trier Social Stress Test for Teens and the Frustration Social Stressor for Adolescents were developed and investigated with early adolescents. Both of these protocols induced a significant stress reaction and evoked predicted bifurcation in cortisol responses; an increase or decrease from baseline to reactivity. In Study I, 120 predominantly middle-class, Euro-Canadian early adolescents with a mean age of 13.43 years were studied. The girls’ attenuated cortisol reactivity to the public performance stressor related significantly to their self-reported lower maternal-attachment and higher trait-anger. In Study II, a community sample of 146 predominantly Euro-Canadian middle-class youth, with an average age of 14.5 years participated. Their self-reports of higher trait-anger and trait-anxiety, and lower parental attachment by both sexes related differentially to accentuated and attenuated cortisol reactivity to the frustration stressor. Thus, attachment, affect, sex, and the stressor contextual factors were associated with the adrenal-cortical responses of these adolescents through complex interactions. Further studies of individual differences in physiological responses to stress are called for in order to clarify the identities of concurrent protective and risk factors in the psychosocial stress and physiological stress responses of early adolescents.  相似文献

ABSTRACT

The eastern Democratic Republic of Congo (DRC) is impacted by a prolonged conflict and humanitarian crisis. Sexual and gender-based violence (SGBV) affects an estimated 39.7% of women and 23.6% of men in the region, and is associated with serious medical, psychological, and socio-economic outcomes for survivors and communities. IMA World Health, a faith-based non-profit organisation, implements a USAID-funded project, Ushindi, which is a collaborative effort with three national NGOs and one technical partner in response to SGBV in eastern DRC. The consortium provides a comprehensive package of services to SGBV survivors, focusing on medical, emotional, psychological, legal, and socio-economic needs.  相似文献

In recent years, the Civil Society Education Fund has supported national education civil society coalitions (NECs) in low-income countries so that they put pressure on governments and donors to implement the Education for All agenda and the Millennium Development Goal on education. This article draws on literature on global governance as well as on an extensive evaluation of the CSEF to explore the actual contribution of this initiative to the activity of NECs. The article highlights the achievements and shortcomings of the CSEF and includes a set of practical recommendations on the role of global civil society in international development processes.  相似文献

Asia is Europe’s largest trading partner and EU-Asia trade relations have undergone a rapid change since the global financial crisis. On a global scale, the new multilateral trade agreements such as the now stalled Trans-Pacific Partnership (TPP) involving European Unions’ (EU) major trading partners such as Japan, Singapore and Vietnam also have the potential to change the trade equations. In this paper, we evaluate the new EU trade policy which has been designed to ensure that the EU benefits from the changing global trade scenario and also look at the steps which have been taken by the EU to promote trade relations with its major trading partners in Asia in the predicted ‘Asian century’. We look into the Free Trade Agreements, which are being negotiated with its Asian partners and seek to understand the reasons which have resulted in delays in their signing and negotiations. We evaluate new policies pushed forward by its Asian partners such as the One Belt One Road policy by China and Japan’s policy of securing a large number of trading agreements in the America. Moving ahead, we also shed light on the indirect factors that may influence the success of EU trade negotiations in Asia such as the EU policy on granting China market economy status and the commencement of the ‘Brexit’ process. Lastly, we try to present a list of immediate priorities for EU in Asia, which will ensure that it secures a toehold in trade with the region. All in all, it is shown that the EU has not one and the same approach for all Asian countries but it negotiates flexibly and individually country by country. Because of this “country by country approach” the EU is also not ready to enter into general EU-ASEAN trade negotiations again.  相似文献

Over the past two decades, earmarked funding to international development organizations through special-purpose trust funds has increased greatly. This paper studies the incentives for trust funds from the perspective of multilateral agencies, notably the World Bank. A theoretically intriguing type of funds are so-called “pass-on funds,” in which one unit hosts the fund, then passes on its resources to another type of unit for implementation. Each unit has different preferences for the specific types of activities to be supported by the fund. Interviews with World Bank staff and complementary documents demonstrate the rationale for pass-on funds and the associated division of labor between fundraising network units and implementing regional units. While pass-on funds reflect an efficient division of labor between functionally specialized units, they increase the misalignment between sector-specific global priorities and country-specific needs. Organizational reform drove the sudden explosion of pass-on funds around the millennium turn, facilitated by growing availability of donor monies for specific sectors and by lenient internal regulation. Organizational reform undermined budget autonomy of sector units, causing those units to seek new funds in their areas of expertise. A number of reform features also reduced administrative budgets of country units, increasing their demand for pass-on funding grants. The results contribute to the emerging literature on earmarked funding and highlight the need to consider international organizations as heterogeneous actors.  相似文献

If solving the global sanitation crisis lies within Indian borders, then it is important to understand the influence of caste relations on sanitation building and usage. Our ethnography investigated three villages in rural Tamil Nadu where seven separate sanitation interventions had failed. The analysis indicates caste relations played a key role in the failed interventions by creating and reinforcing the means by which caste groups distinguished themselves from each other at the village scale. Issues of cleaning, access to subsidies, latrine design, and purity served to facilitate and limit the processes that enable the everyday, unequal relationships of caste.  相似文献

Contrary to the mainstream economic view that unfree labour in the US ended with the Emancipation, this article argues that an unfree labour system continued to dominate southern agriculture in the post Civil War period. Part I details how the southern land tenure system, contract labour laws, and credit system combined to create a social structure of accumulation [Edwards, Gordon and Reich, 1982] that effectively trapped a majority of sharecroppers in debt peonage. However, unlike Ransom and Sutch [1977] I argue that it was the planter and not the merchant, class who were the chief architects and beneficiaries of the unfree labour system. Part II creates a model showing how this ‘unfree’ social structure of accumulation led to the limited and skewed patterns of industrial development, the low level of technological innovation in agriculture, the eventual creation of a large surplus labour pool, and the depressed wage rates that have characterised the American South up to the 1970s.  相似文献
