The accession of the CEE states to NATO and the European Union has put an end to the geopolitical ambiguity and implicit insecurity in the region between Russia and the so-called ‘Old Europe’. Instead of being an area of great powers' rivalry, elements of ‘buffer belts’ lacking meaningful strategic options, objects of raw Nazi-Soviet deals, or zones under Russian occupation and domination, the three Baltic States and the Visegrad group countries became full-fledged members of the European Union and were given NATO's security guarantees. By the middle of the 2000s, one would conclude that traditional geopolitics had ended in this region.However, the changes in the strategic situation in CEE have not changed the deep rooted moving forces and long-term strategic goals of the Russian policy toward the region. Moscow seeks to have the position, as its official rhetoric says, of an ‘influential centre of a multipolar world’ that would be nearly equal to the USA, China, or the EU. With this in view Moscow seeks for the establishment of its domination over the new independent states of the former USSR and for the formation of a sphere of influence for itself in Central Eastern Europe. If it achieves these goals, then Europe may return once again to traditional geopolitics fraught with great power rivalries and permanent instabilities radiating far beyond CEE borders.Yet a few questions remain. Has Russia come to the conclusion that attempting to restore its privileged position of influence in Central-Eastern Europe is wrong? Has Russia enough power to threaten the CEE countries? How credible are NATO's security guarantees? How may Russian behavior in CEE affect a wider European geopolitical context? These questions are appropriate in the light of Russia's ‘resurgence’ as a revanchist power and because Russia is, and most probably will remain in the next five to ten years, a weighty economic and strategic factor in areas along the Western borders of the former USSR.  相似文献

When deciding to resort to a PPP contract for the provision of a local public service, local governments have to consider the demand risk allocation between the contracting parties. In this article, I investigate the effects of demand risk allocation on the accountability of procuring authorities regarding consumers changing demand, as well as on the cost-reducing effort incentives of the private public-service provider. I show that contracts in which the private provider bears demand risk motivate more the public authority from responding to customer needs. This is due to the fact that consumers are empowered when the private provider bears demand risk, that is, they have the possibility to oust the private provider in case of non-satisfaction with the service provision, which provides procuring authorities with more credibility in side-trading and then more incentives to be responsive. As a consequence, I show that there is a lower matching with consumers’ preferences over time when demand risk is on the public authority rather than on the private provider, and this is corroborated in the light of two famous case studies. However, contracts in which the private provider does not bear demand risk motivate more the private provider from investing in cost-reducing efforts. I highlight then a tradeoff in the allocation of demand risk between productive and allocative efficiency. The striking policy implication of this article for local governments would be that the current trend towards a greater resort to contracts where private providers bear little or no demand risk may not be optimal. Local governments should impose demand risk on private providers within PPP contracts when they expect that consumers’ preferences over the service provision will change over time.  相似文献

The main objective of this article is to examine how the links between trade unions and affiliated political parties of the left influenced the strategies of labour during the transition and the early years of democracy in Spain. It argues that political partisanship is a key factor for understanding the unions' strategies. After a period of intense labour conflict during the transition to democracy, labour mobilization decreased and Spain's unions and other social actors initiated distinctive processes of social bargaining, starting in 1979. The central argument is that the relationship of unions and political parties in the authoritarian and transition periods was a major factor in conditioning strategies in the post-authoritarian period. In the end, the consolidation of Spanish democracy has led to the strengthening of the main trade unions. Contrary to what happened in other historical periods they used this power to contribute to governability and the consolidation of the new democratic regime.  相似文献

For students with disabilities, the process of school inclusion often begins with a move from segregated settings into general education classrooms. School transitions can be stressful as students adjust to a new environment. This study examines the adjustment of 133 students with and without disabilities who moved from a school that served primarily students with disabilities into 23 public schools in a large urban school district in the Midwest. These students and 111 of their teachers and other school staff rated the degree that students felt they belonged in their new schools and the quality of their social interactions. Results show that students who experienced more positive and fewer negative social interactions with school staff had higher school belonging. Teachers accurately noted whether students felt they belonged in their new settings, but were not consistently able to identify student perceptions of negative social interactions with staff. Implications for inclusion and improving our educational system are explored.  相似文献

Metropolitan regions have become one of the most appropriate scales to define efficient governance networks for economic and territorial development. The state still is the key actor of these partnerships. Yet the question remains whether cross-border metropolitan regions represent a new point of reference that puts state power in question or whether they only reorganize it. The centrality of state power will be examined by looking at two networks of actors (public transport and territorial marketing) working at the Eurometropolis Lille–Kortrijk–Tournai. The results reveal that a triple-faceted state power has emerged to define and organize cross-border metropolitan management.  相似文献

ABSTRACT

This article examines the participation of some Chinese migrants in illegal gold mining (known as galamsey) in Ghana, and how the Government’s policy to address the issue created diplomatic tension between China and Ghana. Drawing on primary data from in-depth, face-to-face interviews with 250 respondents and supplementary information from archival sources and personal observation, the study found that small-scale gold mining is an area legally reserved for Ghanaian indigenes, who faced stern competition from some Chinese migrants’ miners. Their ability to mobilize resources and machinery to execute galamsey virtually displaced the indigenes from their source of livelihood and caused environmental catastrophes. The Ghana Government’s policy response to the Chinese migrants’ galamsey, which led to arrests, sentencing and deportations of some Chinese miners, angered Beijing and fractured Ghana–China diplomatic ties. But the dispute could not collapse the entrenched bilateral relations between the two nations because the calculated mutual benefit derived from the relations was thought to be higher than the Chinese galamsey issue. Policy reforms which legally integrate Chinese migrants’ miners into the small-scale mining sector would stop galamsey and strengthen Sino-Ghana relations.  相似文献

The nature of citizen participation and engagement in public life in Thailand has changed dramatically over the last decade. This article focuses on explaining the changing pictures of political engagement – political interest, knowledge, and efficacy – among rural and urban Thai citizens since the House of Representatives election in 2001. The major attempt made in this article also to explain how these changes affect patterns of political activism (i.e. in voting, political contacting, and protesting activities), particularly between the rural and urban Thai voters. Relying on three latest survey data taken from the Comparative Study of Electoral Systems, the article suggests that the factors facilitating greater political participation are relatively different between rural and urban residents, and such differences cannot simply be explained as a result of a deeper engagement in the patron–client relationship of the rural than of the urban. Indeed, those differentiations depend on several factors and vary according to different kinds of political activity.  相似文献
