Im Jahr 2005 wurde das Gentechnikgesetz grundlegend novelliert. Damit kam der deutsche Gesetzgeber seinen europarechtlichen Verpflichtungen zur Anpassung des Rechts der Grünen Gentechnik – also der Nutzung gentechnischer Methoden durch Unternehmen der Agro-Industrie und der Saatgutbranche – nach. Neben einer Versch?rfung der Sicherheitsma?nahmen, der Einrichtung eines besonderen Ausschusses für Freisetzung und Inverkehrbringen sowie umfangreicher Regelungen zur Sicherstellung der Koexistenz konventioneller/?kologischer und gentechnischer Anbaumethoden enthielt die Novelle auch die Aufnahme des § 34a in das Bundesnaturschutzgesetzes4. Der neue § 34a BNatSchG soll Fragen des Einsatzes gentechnisch ver?nderter Organismen (GVO) in Europ?ischen Naturschutzgebieten des Netzwerks „Natura 2000“ regeln. Die ersten Praxiserfahrungen mit dieser Vorschrift sind ernüchternd. Den erhofften Schub in Richtung Schutz ?kologisch sensibler Gebiete brachte sie bislang nicht.  相似文献

ABSTRACT

Analyses of United Nations (UN) peacekeeping increasingly consider legitimacy a key factor for success, conceiving of it as a resource that operations should seek and use in the pursuit of their goals. However, these analyses rarely break down legitimacy by source. Because the UN is an organization with multiple identities and duties however, different legitimacy sources – in particular output and procedural legitimacy – and the UN’s corresponding legitimation practices come into conflict in the context of peacekeeping. Drawing on a range of examples and the specific case of the United Nations Organization Mission in the Democratic Republic of the Congo (MONUC), this article argues that looking at different legitimacy sources and linking them to the institutional identity of the UN is thus critical, and it shows how the UN’s contradictory legitimation practices can reduce overall legitimacy perceptions.  相似文献

Little is known about the relative influences of neighborhood and school on the alcohol socialization process. Survey data from the Young in Oslo Study (N?=?10,038, mean age 17.1 years, 52% girls) were used to investigate the details of such influences, using cross-classified multilevel models. School and neighborhood contexts were equally important for ordinary alcohol use; however, neighborhood influences were mainly explained by individual and family factors, whereas peer-based sociocultural processes played a key role in explaining school effects. Neither context had much impact on heavy episodic drinking. The study suggests that “privileged” youth may be at risk of high alcohol consumption. Parental influences and peer-based sociocultural aspects of the school milieu should be considered in prevention efforts.  相似文献

Abstract

Over the last two decades, semi-autonomous revenue agencies (SARAs) have become a key element of public administration reform. They are supposed to improve revenue mobilisation and stabilise state–taxpayer relations. But do SARAs really outperform conventional tax administrations? This article argues that they do. Presenting the results of a panel analysis of local tax collection in Peru between 1998 and 2011, it shows that municipalities with SARAs collect more revenue than those with conventional tax administrations. The results also indicate that local revenue is more stable in municipalities with SARAs, which is good for budget policy and planning.  相似文献

The main aim of this study was to investigate the causal nature of the relationship between adolescents’ risky sexual behavior on the internet and their perceptions of this behavior. Engagement in the following online behaviors was assessed: searching online for someone to talk about sex, searching online for someone to have sex, sending intimate photos or videos to someone online, and sending one’s telephone number and address to someone exclusively known online. The relationship between these behaviors and adolescents’ perceptions of peer involvement, personal invulnerability, and risks and benefits was investigated. A two-wave longitudinal study among a representative sample of 1,445 Dutch adolescents aged 12–17 was conducted (49% females). Autoregressive cross-lagged structural equation models revealed that perceived peer involvement, perceived vulnerability, and perceived risks were all significant predictors of risky sexual online behavior 6 months later. No reverse causal paths were found. When the relationships between perceptions and risky sexual online behavior were modeled simultaneously, only perceived peer involvement was a determinant of risky sexual online behavior. Findings highlight the importance of addressing peer involvement in future interventions to reduce adolescents’ risky sexual online behavior.  相似文献

Intentional self regulation describes how people make choices, plan actions to reach their goals, and regulate the execution of their actions, making processes of intentional self regulation central to healthy human functioning. Prior research has confirmed the presence of three processes of intentional self regulation—elective selection (ES), optimization (O), and compensation (C)—in middle adolescence (Grades 8 through 10) and concurrent and predictive relationships with measures of Positive Youth Development (PYD). A fourth process, loss-based selection (LBS), should also develop by the end of middle adolescence. The present study used data from the 4-H Study of PYD to confirm the presence of a four-scale structure of intentional self regulation (ES, O, C, and LBS) in a sample of 2,357 racially diverse Grade 10 youth (63% female) and examine its covariation with indicators of positive and problematic development. Results supported the identification of a four-part structure of intentional self regulation, and scores covaried positively with indicators of PYD and negatively with substance use, delinquency, and depressive symptoms. Implications of the findings for the understanding of self-regulatory actions in adolescence and for future research are discussed.  相似文献
