International bureaucracies influence global governance processes as independent agents. Biermann and Siebenhüner (Managers of global change: the influence of international environmental bureaucracies. MIT Press, Cambridge, 2009) have developed an analytical framework to measure and explain the degree of autonomous influence of bureaucracies. We test the validity of the causal claims in the framework by applying it to the Division for Sustainable Development, the bureaucracy that services the Commission on Sustainable Development and compare the results with existing applications of the framework to the United Nations Environmental Program and the Climate Secretariat (UNFCCC). The test shows that the framework is comprehensive and captures the main elements of bureaucratic influence. The structure of the explanatory variables, however, as well as some causal claims, needs to be improved. For instance, the framework includes too many explanatory variables, and interplay between the variables is not taken into account. The article suggests five concrete measures to improve the framework by, for example, creating protocols, collapsing variables, and introduce weightings to the variables.  相似文献

We examined whether training in both the verbal and nonverbal indicators of truth telling and lying would have positive effects on Law Enforcement Officers’ (LEOs) ability to evaluate truths from lies. College course-level training on empirically validated verbal and nonverbal indicators of truth telling and lying was provided to mid- to advanced-career level LEOs, whose accuracy in detecting lies from truths was assessed pre- and post-training using truthful and deceptive videos of mock crimes and opinions. A marginally significant truth bias existed at pre-test; training, however, resulted in a significant improvement in accuracy rates for both truth and lie videos, and the truth bias that existed at pre-test was eliminated. Additional analyses indicated that accuracy rates improved for videos of mock crimes but not for opinions. These findings add to a small but growing literature that indicates that training on validated verbal and nonverbal indicators of truth telling and lying has positive benefits.  相似文献

Children and adolescents who are having difficulty coping with stress often present with complaints of physical discomfort. Effective treatment approaches exist for many of these issues. Among high-conflict parents, however, children's medical issues can become another canvas for conflict, with parents focused more on blaming one another for the child's distress than on options for assisting the child. Professionals can be drawn into the conflict to such a degree that they overlook essential steps for addressing and managing these issues. The authors present a research-informed model for managing medical and psychophysiological issues amid parental conflict.  相似文献

The difference in official crime statistics between women and men is a constant fact in criminology, but has yet to be explained in a satisfactory way. There are few studies addressing the issue of why this gender gap is larger in registered crime than it is in self-report studies. The study at hand comprises a survey among Greek and German students to examine whether this gap could be attributed to a gender-specific reporting of crime. Participants’ self-reported experiences of victimisation and their rating of the seriousness of offences depicted in case vignettes were used to gain insight into varying tendencies to report a crime depending on the offender’s gender. The act of reporting a crime did not vary gender-specifically.  相似文献

Maximum security correctional officers play a crucial role in the establishment of order within their respective institutions of employment, yet they are also exposed to numerous occupational dangers that can threaten their general welfare. When they perceive high levels of injurious risk from workplace hazards, this cannot only jeopardize their job performance but lead to a poorly managed prison institution. Currently though, few studies have explored correctional officer perceptions of workplace dangers and risks, and even fewer have explored the factors that influence officer perceived risk of injury. Questionnaire data from a statewide population of maximum security correctional officers (N?=?649) were gathered in order to examine officer perceived risk of injury from workplace dangers, and the antecedents to this judgment. Results illustrated how officers perceived a high degree of injurious risk from their work, and that their risk perceptions were largely a product of psychological features of dangers. Theoretical and policy implications are discussed.  相似文献

Public‐Private Partnerships (PPP) procurement is routinely portrayed as offering greater scope for harnessing competitive market forces to secure Value for Money (VfM) than traditional procurement approaches ( OECD 2008 ). The aim of this article is (a) to demonstrate the importance of periodically taking a more systematic and strategic view when assessing VfM in PPP procurement ( OGC 2003 ), and (b) to develop an analytical framework for such an analysis. Road infrastructure procurement in South East Queensland is used as a case study to test the usefulness of the proposed framework, and to show how a narrow focus on individual contracts increases the risk of overlooking overdependence on one supplier ( OGC 2003 ). Discussion focuses on the need to combine detailed analysis of individual contracts with longitudinal analyses of market competitiveness when assessing best VfM.  相似文献

This study examines the role of public–private partnerships (PPPs) in promoting pro‐poor productivity‐enhancing technological innovation in the international agricultural research system. The study examines the extent to which PPPs are being used to overcome market and institutional failures that otherwise inhibit the development and dissemination of technologies targeted specifically to small‐scale, resource‐poor farmers in developing countries. Drawing on a survey of 75 PPP projects in the international system, findings suggest that while PPPs are changing the way the system manages its research agenda, few partnerships lead to joint innovation processes with the private sector. This indicates the need for closer examination of organizational practices, cultures, and incentives in the international agricultural research system.
