The Sustainable Development Goals (SDGs) herald a new phase for international development. This article presents the results of a consultative exercise to collaboratively identify 100 research questions of critical importance for the post‐2015 international development agenda. The final shortlist is grouped into nine thematic areas and was selected by 21 representatives of international and non‐governmental organisations and consultancies, and 14 academics with diverse disciplinary expertise from an initial pool of 704 questions submitted by 110 organisations based in 34 countries. The shortlist includes questions addressing long‐standing problems, new challenges and broader issues related to development policies, practices and institutions. Collectively, these questions are relevant for future development‐related research priorities of governmental and non‐governmental organisations worldwide and could act as focal points for transdisciplinary research collaborations. 相似文献

This paper applies the patrol-initiated-activity hypercube queuing model to historical data from a police agency. The model allows servers to handle both calls assigned by a central dispatcher and activities initiated by the servers. By duplicating a fairly complex dispatch strategy, the model was found to predict both assigned and server-initiated work loads accurately for the overall system and individual servers. The model is apparently ineffective in predicting small unit-travel-time differences for this police agency. 相似文献

The maximum expected covering location problem (MEXCLP) is reformulated using a separable programming approach. The resulting formulation—nonlinear maximum expected covering location problem (NMEXCLP)—guarantees optimality and also solves more quickly than previous heuristic approaches. NMEXCLP allows two important extensions. First, minor formulation changes allow the specification of the minimum number of times each node is to be covered in order to satisfy expected coverage criteria. Second, coverage matrices can be constructed that consider two different types of coverage simultaneously. Both extensions are useful for ambulance location problems and are demonstrated in that setting. 相似文献

This paper describes the development and evaluation of the Abortion Attributes Questionnaire (AAQ), an instrument designed to assess the perceived importance of specific characteristics of abortion methods. Women receiving medical abortions ( n = 186) and women who chose surgical procedures ( n = 118) completed the AAQ. Participants were asked to rate how important each of 21 characteristics would be "when choosing between surgical and medical abortion." Factor analyses revealed that the AAQ consists of four factors and, as subscales, the factors have good internal reliability. The validity of the AAQ was established through discriminant function analysis and results indicated that three of the four factors predicted choice. Taken together, these findings provide empirical support for the constructs measured by the AAQ . 相似文献

Clinical studies of children in international adoption reveal unique patterns of psychological adjustment to permanent family care. Pre‐adoption history often includes early object loss, medical and nutritional deprivation, multiple care‐giving disruptions, and the lack of primary care‐giving relationships. These factors and the age at the time of adoption are risks to positive emotional and cognitive development. Adoptive parents may be unprepared for the resulting developmental problems. Most significantly, parents and children are often at different points in readiness to establish an attachment relationship. The parents are eager to claim their child, but the child is unready to respond because of emotional fragility and lack of previous attachment experiences. Two clinical vignettes illustrate the importance of a developmental and medical framework in assessing the unique needs of these survivor children, as well as the necessity of an empathic therapeutic holding environment that can sustain the emerging family attachments under stress. The psychological impact of cross‐cultural adoption and traumatic early beginnings reverberates across time but with empathic parental care and treatment recovery can be significant. 相似文献

Objective. An individual's personal experiences and perception of the collective experience are often linked to political attitudes, especially those concerning the national economy. In this article, we examine whether personal concern about terrorism and perceptions of public concern about terrorism affect attitudes about counterterrorism policies. In addition, we evaluate which factor is the strongest predictor across several counterterrorism policies. Method. We analyze individual‐level survey data collected during the fall of 2001. Results. Our results indicate that perceptions of public concerns are the strongest and most consistent predictor of policy attitudes about terrorism. Conclusion. The implications for theory about perceptions of public opinion and the competing role of personal interest and sociotropic concern are discussed. 相似文献

ABSTRACT This is the first published account of state administrative code variations in nursing home social worker qualifications. It is important to review state codes because the majority of nursing homes in the U.S. have fewer than 121 beds and therefore are not required by the federal government to employ at least one full-time qualified social worker. States have the option of extending the federal regulations to homes with 120 or fewer beds, or strengthening the federal requirements in other ways. Findings indicate enormous variation in state requirements for qualifications of nursing home social workers, and even when states define a qualified nursing home social worker (not all do), they often exempt facilities from employing one. Seven states were found to be out of federal compliance. Research describing the qualifications of people employed in nursing home social services is called for, as well as research documenting effective psychosocial interventions, especially as they relate to resident quality of life. Ten recommendations for enhancing nursing home social work services are included. 相似文献

The paper represents a further development of work previously reported in this journal by Spratt & Houston (1999) and Spratt et al. (2000) . The authors have sought to develop ways of understanding current social work with children and families in line with the critical theory of Jurgen Habermas. This analysis has been complemented by an adoption of the methodology of the radical dramatist, Augusto Boal. In synthesizing Habermas's analysis of communicative discourses with the consciousness raising methodology of Boal, the authors have already demonstrated the effectiveness of this hybrid in problem‐solving exercises with social workers. The present paper reports on an application of this developing theory to practice, utilizing the centrepiece of Boal's method, forum theatre. A forum theatre project, concerned with the issue of bullying, is described and evaluated. It is argued that the project provides an exemplar of an innovative, democratizing and effective methodology that might profitably be utilized in social work with children and families. Finally, suggestions are made as to how these ideas could be developed in practice. 相似文献
