This article investigates political opportunities and constraints associated with incorporating the concept of universal citizenship into migration debates. Analyzing the speeches of Ecuador's president Rafael Correa over eight years, the article argues that Correa strategically crafted a narrative of universal citizenship to undergird politically beneficial policies. Political constraints from constituents and rivals, and the populist nature of his governing style, hollowed out progressive migration policy innovations to the point that universal citizenship became a rhetorical device more than a substantive policy agenda. Through this empirical case, the article develops a more nuanced critical understanding of universal citizenship discourses as sites for negotiating the relationship between states and migrants.  相似文献

Recent studies on European Union (EU) Enlargement have emphasised the importance of usages of ‘Europe’ by domestic actors as a necessary condition for the EU to have an impact on domestic politics. We study the usages of Europe in the critical case of Turkey’s nuclear energy policy. We analyse the narratives and actions of domestic actors in Turkey to identify if they use ‘Europe’ (the EU and the idea of Europe). We reach the counter-intuitive finding of usages by both state and non-state actors, which illustrates that usages of Europe can persist despite enlargement stasis in candidate states.  相似文献

Open governance requirements are designed to improve accountability, which implies that transparent governments are more trustworthy stewards of their publicly invested power. However, transparency may also reduce institutional effectiveness and inhibit political compromise, diminishing the capacity to manage resources responsibly. We assess empirical support for these competing perspectives in the context of American state legislatures, many of which have become exempt from state sunshine laws in recent decades. We leverage variation in the timing of these legislative exemptions to identify the effect of removing transparency in a crucial governing institution on investors’ risk perceptions of states’ general obligation bonds. Our analysis of these data during the period 1995–2010 suggests that removing legislative transparency reduces state credit risk. We conclude that while openness in government may be normatively desirable, shielding legislative proceedings from public view may actually be better for states’ debt repayment capacity, improving their overall fiscal health.  相似文献

Community, demographic, familial, and personal risk factors of childhood depressive symptoms were examined from an ecological theoretical approach using hierarchical linear modeling. Individual-level data were collected from an ethnically diverse (73% African-American) community sample of 197 children and their parents; community-level data were obtained from the U.S. Census regarding rates of community poverty and unemployment in participants’ neighborhoods. Results indicated that high rates of community poverty and unemployment, children’s depressive attributional style, and low levels of self-perceived competence predict children’s depressive symptoms, even after accounting for demographic and familial risk factors, such as parental education and negative parenting behaviors. The effect of negative parenting behaviors on depressive symptoms was partially mediated by personal variables like children’s self-perceived competence. Recommendations for future research, intervention and prevention programs are discussed.

In 2005 Indonesian and European institutes joined to start the first step for the implementation of an Ocean Operational System in the Indonesian archipelago. The system will support the decision making process for the sustainable use of marine resources, providing useful information and added value products as well as a service for an improved management of the sea with high business impact to targeted groups as public authorities and commercial operators (coastal managers, fishermen, shipping companies). In this paper the System is shortly described with its potential benefits and economic and social impacts.
