Abstract

Despite shared historical experience and cultural proximity, the Visegrad group (V4) struggles to institutionalise its cooperation through stable mechanisms ensuring internal cohesion and external credibility. This is especially evident in the field of security and defence, which requires a shared strategic vision, in particular, common norms regarding the legitimate use of military force. While in the 1990s the four countries exhibited solidarity and unity in their collective ambition under the narrative of the ‘Return to Europe’, their general perception of security threats and strategic culture prevents deeper integration into a security community.  相似文献

This article analyses how a gendered perspective on community-based tourism (CBT) contributes to the realisation of identity and sovereignty of quilombos. It examines the potential sustainability of CBT coupled with agro-ecological practices within the context of gendered identity politics. Drawing from in-depth ethnographic and archival research conducted between February and July 2015 at Campinho da Independência (Rio de Janeiro, Brazil), the article discusses how female leaders integrate sustainable agro-ecological practices and CBT with environmental education in what they call ‘ethno-ecological tourism’. This approach to CBT strengthens a proudly defiant version of Afro-Brazilian ethnic identity vis-à-vis the state.  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
