The present work has a two-fold aim: (a) to verify the difference in civic behavior enacted by socially engaged young people in a lasting and structured form, sealed by membership in an organization, on the one hand, and in non-engaged young people, on the other hand; (b) to identify a pattern of characteristics (personal, social, and familial) able to explain civic behavior. Participants, 577 young adults from ages 19 to 29, filled out a self-report questionnaire. The results of the t test for independent samples confirm the presence of the difference between means of scores on the civic behavior. Moreover, data confirm a model in which civic behavior is predicted by personal identity, engagement values, family discussion of current events, the quality of previous membership experiences in socially oriented groups (membership), and finally, in a mediator position, by sense of community. The present study has many implications for researchers and practitioners.  相似文献

Capillary electrophoresis coupled to time-of-flight mass spectrometry was used in the present work for the determination of therapeutic and abused drugs and their metabolites in the hair of subjects undergoing addiction treatments, in order to monitor their compliance to therapy. For this purpose a rapid, qualitative drug screening method was adopted based on capillary electrophoresis hyphenated with time-of-flight mass spectrometry, which had earlier been developed and validated for the forensic-toxicological analysis of hair, limitedly to illicit/abused drugs [1]. Sampling of hair was carried out in order to refer to a time window of about two months from the date of sampling (i.e. 2cm ca. from cortex). A single extraction procedure was applied, allowing the determination in the hair matrix of "drugs of abuse" referred to the past abuses, and therapeutic drugs prescribed in the detoxification program as well as their metabolites. Analyte identification was based on accurate mass measurements and comparison of isotope patterns, providing the most likely matching between accurate mass value and elemental formula. Small molecules (<500Da) of forensic and toxicological interest could be identified unambiguously using mass spectrometric conditions tailored to meet a mass accuracy ≤5ppm. In the present study, the proposed approach proved suitable for the rapid broad spectrum screening of hair samples, although needing further confirmation of results by using fragmentation mass spectrometry.  相似文献

Abstract:  Despite the fact that Interinstitutional Agreements (IIAs) are an established part of the mass of informal and formal rules structuring EU decision-making and interinstitutional relations, there is as yet no common understanding of their role and functions in the institutional and legal system of the EU—neither in political science nor legal studies. Tracking the evolution of the European Parliament's competencies in three areas where IIAs figure prominently—comitology, legislative planning, and the establishment of procedures to hold the Commission accountable—this article seeks to show that the European Parliament strategically uses IIAs as instruments to wrest competencies from the Council and the Commission. Having no formal say in treaty reform, the European Parliament 'creates facts' through informal but politically binding IIAs hoping that, once established, it can achieve a later codification of its new rights at IGCs. Viewed this way, the analysis of the role of IIAs in Treaty Reform could help to explain a still under-researched puzzle in European integration theory, namely the incremental parliamentarisation of the institutional system of the EU over the last two decades.  相似文献

By extending existing theories of legislative speech making, this study explores the importance of parliamentary rules governing floor debates for government and opposition parties. An original data set including speeches of members of the Italian Chamber of Deputies between 2001 and 2006 is used to test two hypotheses under different institutional scenarios, that is, rules either restricting or granting open access to the floor. Parliamentary rules are found to affect allocation of speaking time within both governing and opposition parties. Governing parties' leaders exploit their agenda control to a higher degree when allocating speaking time. Under restrictive rules, government party leaders control their MPs by essentially limiting the number of speeches and allocating them to frontbenchers. Restrictive rules give opposition party leaders an important chance to select MPs who are closer to their own position.  相似文献

Europe’s woes mark a new chapter in the longstanding theory/history nexus in European studies. The euro crisis has brought integration theory back onto the scholarly agenda and highlighted the value of neo-functionalism – and more precisely its key ‘spillover’ mechanism – as a framework for interpreting current politico-institutional dynamics in the European Union. We are, however, at a particular point of the neo-functionalist narration, in which the transition from low to high political integration has opened a phase of political fluidity that makes ideas and political leadership crucial in determining the future course of integration. In this phase, the positive scheme of neo-functionalism and the normative one of federalism come together, bringing the intellectual trajectory begun after WWII to full circle. Whether this new encounter will result in further integration depends primarily on the content of new federalist ideas, the emergence of an effective European leadership, and the presence of a favourable international environment. For all three factors, the record so far has been mixed at best.  相似文献
