Human security has increasingly shifted attention to the individual, while the state has become guarantor (or violator) of security given its role in governing the domestic environment. This article examines how variations in regime forms influence security, pointing to the importance of political security in the wider human security framework. To illustrate, the article examines the nature of political security in Central America, a region with weakly democratized states and histories of political violence. The findings suggest a link between democracy and human security that is mediated by state capacity and the ability to control non-state violence against individuals.  相似文献

The AIDS Risk Reduction Model (ARRM) is a conceptual model designed to explain the influence of knowledge and attitudes about AIDS/HIV on risk-related behaviors. This article measures the influence of the primary concepts associated with the ARRM (labeling, commitment, and enactment) on high-risk adolescent's knowledge, attitudes, and self-reported behaviors. Data were collected from 393 adolescents incarcerated in juvenile detention facilities. Ordered probit and ordinary least squares (OLS) analyses were conducted to determine which of several independent variables have the most impact on acceptance of the ARRM. Results indicated that the ARRM is effective for understanding the factors that influence AIDS risk avoidance. Findings also indicate that previous life experiences should be formally integrated into the model. Moreover, specific forms of enactment are associated with different factors. Suggestions as to how the ARRM may prove useful for promoting behavioral change among high-risk adolescents are provided.  相似文献

Der Beitrag befasst sich mit der Entwicklung, der Lage und den möglichen Veränderungen des deutschen Föderalismus im Hinblick auf das Umweltrecht. Die bisher in der Kommission zur Modernisierung der bundesstaatlichen Ordnung geäußerten Vorschläge können nur teilweise überzeugen. Zu empfehlen ist insbesondere ein einheitlicher Kompetenztitel des Bundes für den Umweltschutz im Bereich der konkurrierenden Gesetzgebung. Allgemein sollten die Rahmengesetzgebung und die Grundsatzgesetzgebung ebenso entfallen wie die Möglichkeit des Bundes, gemäß Art. 84 Abs. 1 GG künftig weiter die Einrichtung und das Verwaltungsverfahren der Landesbehörden zu regeln. Im Übrigen erscheint die Beteiligung der Länder an der europäischen Gesetzgebung reformbedürftig. * Frau Christina Hakel sowie Herrn Volker Ochsenfahrt, Berlin, danke ich für die wertvolle Mitarbeit.  相似文献

All countries are eager to attract as much foreign direct investments (FDI) as possible. At the same time FDI may have not only positive, but also negative economic effects for receiving countries. Positive effects are associated with technology transfer, efficient allocation of resources, and training of domestic workers. However, the entry of foreign firms could, e.g., lead to a decrease of labor productivity at domestic firms, which is a negative effect. The main purpose of this paper is to estimate direct and indirect effects of FDI. First, we test for direct influence of foreign direct investments on firms’ performance, where the latter is estimated alternatively as labor productivity and as exports. FDI notably increases both labor productivity and export volumes. Second, we look for spillover or indirect effects. There is statistical evidence that the levels of FDI in certain regional industries are associated with higher performance indicators of firms’ not receiving FDI in those same regional industries.  相似文献

This article describes the impetus for a research project conducted during 2002–2003 into our law students' experiences of undertaking a dissertation module. It also discusses the rationale for the particular methodology and approach we have used to conduct this research, and presents the results. A driving force behind this research project was not only the desire to obtain knowledge for its own sake but also the need to identify and enhance positive aspects of students' experience of this module. We decided to adopt a student led and experiential method of carrying out our research that focuses directly upon the students' lived-experience of engaging in dissertation writing. The rationale for this decision was our acknowledgement that, within the last decade, students are increasingly defining themselves as consumers of educational services and have a legitimate and indeed pivotal role in quality assurance strategies. We also recognised that adopting an experiential method of inquiry, informed by a phenomenological approach, should, in principle, help to empower students by acknowledging their autonomy and encouraging them to engage in critical reflection. Finally, applying this methodology would provide us with precisely the subjectively rich type of research data derived from the students' lived-experience that we sought. This revised version was published online in July 2006 with corrections to the Cover Date.  相似文献
