This paper examines the goals of organizations that sponsor short-term volunteer trips in global health, whether they be NGO’s, faith-based, educational, or corporate organizations. Results from a U.S.-based national survey of 177 such organizations and 27 interviews with trip organizers suggest that organizations often sponsor volunteer trips to achieve goals that are quite different from the improvement of health outcomes in poor countries. While providing health services is often cited as the most important goal, volunteer activity is also considered important in enhancing the organizations’ reputation, recruitment and retention, and financial well-being. The prominence of other goals has the potential for diverting resources and focus from what is presumably the primary purpose of serving host communities in the most effective manner possible.  相似文献

Multiple organizations and institutions have been resorting to indicators on diverse aspects of culture (e.g., creativity, social cohesion, cultural vitality, economic participation), according to their particular purposes and views of what is to be measured. This paper presents results from a research report of a qualitative study that analyzed 35 papers on cultural indicators found via Internet, based on four categories: purpose, assumptions about culture, concept of culture they sustain, and dimensions of indicators considered. Results show that even when the importance of culture is widely recognized in the papers, most of them propose indicators without having solid theoretical foundations, and with an emphasis on the relation between culture and economy. Also, most of the documents do not have a definition of culture or present an instrumental conceptualization of it, where culture is valued not as an end in itself but as a resource than can serve to development.  相似文献

A remarkable out‐migration from Kosovo occurred after the winter 2014/15, raising urgent questions about its underlying drivers and implications for both Kosovo and the destination countries. This article aims at providing a better understanding of key migration triggers and some particularities of the phenomenon. We link our empirically found migration drivers to Hirschman's ( 1970 ) famous exit, voice or loyalty scheme by asking in how far the exit must be understood as the explicit alternative to voicing dissatisfaction with the current situation in the country. According to our results, the recent Kosovar out‐migration is a clear response to weak governance and thus goes beyond the widespread ‘migration‐cum‐remittances’ livelihood practice. In this sense it could be interpreted as a revolt against the political system. With view to policy implications for destination countries, we point at legal travel and migration opportunities as the better solution to channel both voice and exit.  相似文献

Competing risks occur in a time-to-event analysis in which a patient can experience one of several types of events. Traditional methods for handling competing risks data presuppose one censoring process, which is assumed to be independent. In a controlled clinical trial, censoring can occur for several reasons: some independent, others dependent. We propose an estimator of the cumulative incidence function in the presence of both independent and dependent censoring mechanisms. We rely on semi-parametric theory to derive an augmented inverse probability of censoring weighted (AIPCW) estimator. We demonstrate the efficiency gained when using the AIPCW estimator compared to a non-augmented estimator via simulations. We then apply our method to evaluate the safety and efficacy of three anti-HIV regimens in a randomized trial conducted by the AIDS Clinical Trial Group, ACTG A5095.  相似文献

Academic entrepreneurship, which refers to efforts undertaken by universities to promote commercialization on campus and in surrounding regions of the university, has changed dramatically in recent years. Two key consequences of this change are that more stakeholders have become involved in academic entrepreneurship and that universities have become more ‘strategic’ in their approach to this activity. The authors assert that the time is ripe to rethink academic entrepreneurship. Specifically, theoretical and empirical research on academic entrepreneurship needs to take account of these changes, so as to improve the rigour and relevance of future studies on this topic. We outline such a framework and provide examples of key research questions that need to be addressed to broaden understanding of academic entrepreneurship.  相似文献

Infants placed in foster care are at high risk for emotional and behavioral problems. Assessment of their mental health must account for their often-adverse life experiences prior to placement and the involvement of multiple systems that shape their lives in lieu of parents' authority. This article presents practice guidelines for infant mental health evaluations with consideration of legal requirements and the unique issues conferred by foster care.  相似文献

Using meta-analysis, we find a consistent positive correlation between emotion recognition accuracy (ERA) and goal-oriented performance. However, this existing research relies primarily on subjective perceptions of performance. The current study tested the impact of ERA on objective performance in a mixed-motive buyer-seller negotiation exercise. Greater recognition of posed facial expressions predicted better objective outcomes for participants from Singapore playing the role of seller, both in terms of creating value and claiming a greater share for themselves. The present study is distinct from past research on the effects of individual differences on negotiation outcomes in that it uses a performance-based test rather than self-reported measure. These results add to evidence for the predictive validity of emotion recognition measures on practical outcomes.

The paper begins by outlining the development of social indicators work and social monitoring at the national level in New Zealand and comments on how this relates to the international movement. It describes the 'key' indicators/life stage approach developed by the New Zealand Planning Council in the early 1980s. This exercise continues from a university base and the fourth report in the series, entitled Tracking Social Change in New Zealand was published in early 1998. Examples are presented to show how the results can be used to highlight the policy implications of changing social trends.  相似文献

Defences of the youth wage constitute a form of discrimination against young people with significant implications for income poverty among 16–24 year olds in Australia. In a manner comparable to the historic denigration of women and Indigenous Australians, arguments against the equal value of youth work rest on normative and empirical assumptions that are entirely contestable. Ultimately, they embody an animus against a section of the population that deprives them of their fundamental civic status.  相似文献
