ABSTRACT

Increasingly, a diverse set of policy communities, including those with defence, development and environmental mandates, frame climate change as a security threat. Most often this discursive formation labels climate change as a ‘threat multiplier’. This framing, however, is vague, linear and leaves many questions unanswered regarding how institutions can develop and implement policy that addresses the joint challenges of climate change, conflict and security. Utilising a mixed-methods approach, and grounding data collection in US policy communities, this article examines how policy actors and institutions integrate climate-security discourses into policy processes. The objective of this research is to provide direct insight into how the discourses and technical understandings of climate-security transition into policy priorities and implementation realities. This research identified three common approaches to climate-security: (1) A challenge of adaptation and resilience; (2) A potent political argument; and (3) An issue of limited importance and feasibility. These approaches, however, are inconsistent across sectors and within organisations, suggesting a lack of cohesion and considerable challenges in identifying and responding to climate change as a ‘threat multiplier’.  相似文献

This article examines the effects of negotiation practices, such as coercion and contract formality, on how suppliers and customers perceived the resulting business relationship. We conducted a purchasing negotiation simulation with students in a classroom setting in which participants competed for resources in a mock supply-chain context. The participants were surveyed at key stages of the ongoing negotiation in order to measure their behaviors as a customer–supplier relationship developed. The data were used to test several hypotheses developed from the marketing and purchasing literature. The hypotheses were analyzed using structural equation modeling.
Results demonstrated that the use of coercive techniques by negotiators during negotiation had a negative effect on satisfaction. In addition, the findings showed that, as expected, negotiators entering a negotiation with a cooperative orientation would tend to avoid the use of coercive practices during negotiation. The cooperative orientation also exhibited an unexpected positive effect on the formalization of the design of the contract between the parties. This study contributes to the current knowledge base focusing on the creation of agreements between companies and will, we hope, encourage the integration of suppliers and customers in an operating context within a supply-chain setting.  相似文献

Community-based delinquency prevention programs, designed to work with youth and families before they become involved with the official court process, are relatively rare. Likewise, few studies have been published concerninge valuative research on such programs. This article reviews some background on program concepts, describes the operations of the Oakland County Probate Court Youth Assistance casework services program, and reports the results of a comprehensive program evaluation project. The findings suggest that prevention programming is one effective strategy to aid in reducing the likelihood of more costly court interventions. Recommendations for program development are offered.  相似文献
