What is required for sustaining an alliance between union and environmental activists? Applying grounded theory to a case study in the Costa Rican banana sector, this article reveals five historical phases. First, unions and environmentalists identify common opportunity structures for joint action. Second, a preexisting network becomes a resource for mobilization. Third, the new coalition engages in communicative action that leads to shared identity and cultural framing and a foundation for handling exogenous global forces. Market policy changes in the fourth phase stimulate a transnational activist network and framing linkages. Dramatic supply disruptions in the fifth precipitate autonomous organizational approaches that require reframing, identity extension, and flexibility. This study argues that the Costa Rican case can be generalized to other labor‐environmental coalitions if such alliances create simple, open structures that agilely adapt to external opportunity structures and expand frames that encourage collaborative autonomy and dualistic collective definitions.  相似文献

This article evaluates the effectiveness of OAS mechanisms for safeguarding democracy through multilateral diplomacy, what some scholars have dubbed the interamerican defense of democracy regime. Drawing on a range of international relations theories, this study derives competing hypotheses about member states' responses to democratic crises in the Americas. It then analyzes all instances in which a collective response—that is, an application of Resolution 1080 or the Inter-American Democratic Charter—was debated in the OAS between 1991 and 2002. Patterns of state behavior suggest that domestic politics, rather than the structural or systemic traits of the interamerican system, best explain foreign policy responses to crises of democracy in the region. The OAS record in confronting such crises is uneven.  相似文献

This article is the result of a master's thesis about children and their universal right to be included in a family environment. This is not only protected under international law, but also intuitive to human beings. HIV‐AIDS continues to threaten lives of children, particularly in sub‐Saharan Africa in the form of orphaning. Looking at a case study from Kenya, it is revealed that, while legal protection is yet to be fully realized in the state, strong cultural norms of value are alive. Currently, the extended family system is the greatest protection to children orphaned or at risk of being orphaned. However, this system was made invisible in the domestic laws of Kenya under the Children Act 2001. This neglect calls for questions not only regarding the protection cultural norms may offer, according to the best interests of children, but also as to the cultural environment being created with the new law.  相似文献

The Rehabilitation Engineering Research Center on Technology Transfer (T2RERC) hosted a “State of the Science” conference in November, 2001. The conference reviewed technology transfer work within the field of assistive technology, and summarized related work in public, private and academic sectors. Invited speakers prepared papers on various topics concerning technology transfer, and related their findings to the field of assistive technology during the ensuing discussion sessions. This paper provides an overview of the material presented by the participants, and explores the implications of their findings for one particular field of application—assistive technology for people with disabilities.  相似文献

Diese übersicht enth?lt eine Aufstellung wichtiger zwischen 6. Oktober und 10. Dezember 2009 von der Europ?ischen Kommission verabschiedeter Vorschl?ge für von Rat und Europ?ischem Parlament zu beschlie?ende Rechtsakte, sowie von Initiativen der Mitgliedstaaten und Entwürfen des Rates im Rahmen des Titels VI des Vertrages über die Europ?ische Union. Zus?tzlich wird auf rechtspolitisch interessante Texte der Europ?ischen Kommission wie zB Grünbücher oder Erfahrungsberichte hingewiesen. Damit soll dem Leser die M?glichkeit gegeben werden, in einem m?glichst frühen Stadium von neuen Entwicklungen im Gemeinschaftsrecht Kenntnis zu erhalten. Die übersicht enth?lt umgekehrt keine Angaben über vom Rat endgültig verabschiedete Texte. Als Fundstelle wird grunds?tzlich die Referenz des Kommissionsdokumentes angegeben (COM, SEC). Soweit nicht anders angegeben, handelt es sich um EG- (und nicht EAG-) Rechtsakte.  相似文献
