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

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

Blood was available for the estimation of carboxyhemoglobin saturation (COHb) in 30 of the 173 persons who died in the Victorian bushfires in February 2009. The ages of these 30 deaths ranged from 3 to 80 years and there were 8 females. 13 cases (43%) were considered negative (less than 5% COHb), 12 (40%) were between 5 and 40% COHb, 2 (6.7%) between 40 and 50% and 3 (10%) were greater than 50% COHb. There were 6 persons either found within a building or a car and the COHb in these cases ranged up to 69% (mean 50%). There were 5 cases where the location was unable to be determined as either indoor or outdoor due to the extensive nature of the fire. The remaining 19 deceased persons were all located outside in the open and the concentration of COHb in these cases ranged up to 30% (mean 19%). Hydrogen cyanide was only detected in two deceased persons at concentrations of 0.5 and 2.7 mg/L, respectively. 13 deceased were found to have soot in the airways following necropsy but this did not correlate with the COHb levels. 相似文献

The conventional view of the life‐course of social movements is that they institutionalise, develop hierarchical structures and, as a consequence, de‐radicalise. This article assesses this image by examining the recent history of the German environmental movement, using two surveys of national and Berlin‐based environmental groups. The analysis suggests that there are no indications of a decline or sclerosis in the movement. Contrary to what some observers have claimed, we find at least a stable number of groups, an increase in the size of their membership and other resources, as well as the maintenance of a decentralised movement structure. Moreover, empirical evidence does not lend support to the idea that the movement, at the aggregate level, has been pacified in terms of its protest. 相似文献
