The article evaluates the pre-accession experience of new European Union member-states, coming from the former Eastern bloc, estimating an empirical model used to account for regional–industrial employment growth in the early transition period, 1991–2000. The results obtained indicate the adverse impact of the economic integration dynamics and detect the interplay among structural characteristics and geographical coordinates that determines the relative winners. The findings of the article have important implications for both theory and policy.  相似文献

There is a growing demand for more cost-efficient production processes in Statistical Institutes. One way to address this need is to equip Statistical Information Systems (SIS) with the ability to automatically produce statistical data and metadata of high quality and deliver them to the user via the Internet. Current approaches, although provide for the storage of appropriate metadata, do not use process metadata for guiding the production process. In this paper we present an approach on creating SISs that permits metadata-guided statistical processing based on an object-based, statistical metadata model. The model is not domain specific and can accommodate both microdata and macrodata. We have equipped the model with a set of transformations that can be used to automatically manipulate data and metadata. We show the applicability of transformations with some examples using actual statistical data for R&D expenditures. Finally, we demonstrate how the presented framework can be exploited for the construction of a web site that offers ad hoc query capabilities to the users of statistical data.  相似文献

Regional inequalities in Greece   总被引:1,自引:0,他引:1  
This article examines regional inequalities in Greece, on the basis of -convergence and -convergence analysis and shows that they were reduced in the 1970s and the 1980s. Regression analysis indicates that regional inequalities have a pro-cyclical character, increasing in periods of economic expansion and decreasing in periods of economic recession. It also indicates that the structure of local industry, the process of EU integration, the quality of human capital and the existence of resources suitable for the development of tourism are among the factors affecting regional growth.

In my car the brake is on the right: pedal errors among older drivers   总被引:1,自引:0,他引:1  
PURPOSE: To assess to what extent specific cognitive functions contribute to pedal errors among older drivers. METHODS: 180 subjects aged 65 and older completed a 30 min driving evaluation on a simulator as well as three cognitive tests, the Mini-Mental State Exam (MMSE), the Clock Drawing Test, and Trailmaking Part A and B. Analyses based on logistic regressions were performed using age, gender, MMSE, Trailmaking Part A and B, and Clock Drawing Test as independent variables. RESULTS: Results indicate that Clock Drawing is the best predictor of pedal errors (odds ratio=10.04, p<.0001, 95% CI: 3.80, 26.63) followed by age > or =84 (odds ratio 6.10, p<.05, 95% CI: 1.77, 21.03). In contrast, Trailmaking Part A and B, gender, and the MMSE were not significantly related to pedal errors. CONCLUSION: Executive dysfunction may be an important contributor to pedal errors and thus unsafe driving. Practitioners may wish to consider measures of executive function when evaluating patients for driving safety.  相似文献

The countries belonging to the European Neighborhood Policy (ENP) of the EU are characterized by significant socioeconomic transformations and—more recently—by disconcerting instances of social and political turmoil. This comes to add to social and economic pressures applied to these countries under their process of market liberalization and economic integration, instigated at least in part by the very ENP process. In those conditions, questions of spatial cohesion and thus of regional convergence and divergence become increasingly salient, as the elimination of (social and) spatial imbalances is both a precondition for the legitimacy and successful implementation of the reforms aiming at market liberalization and economic integration and a core objective of such reforms. In this paper, we examine the spatial dynamics of population growth in the ENP countries prior to the recent destabilization in the region, using two complementary approaches—an analysis of the impact of agglomeration on growth and an analysis of club formation in population concentrations (convergence–divergence). We find that, on the whole, the ENPCs South space was characterized in recent years by evidence of regional convergence in the sense that population concentrations were becoming more diffused across regions; while the ENPCs East exhibited stronger and more consistent evidence of regional divergence (increased concentration of population). These findings suggest that agglomeration and cumulative causation forces are more strongly in operation in the more advanced, at least in terms of EU relations, countries of the ENP East, where also the “pull” factor of the EU economy is stronger.  相似文献
