Die europ?ische Fischerei muss sich zur Zeit einer Vielzahl von Problemen wie sinkenden Fangmengen, abnehmenden Ums?tzen sowie
einem stetigen Besch?ftigungsabbau stellen. Einer der Hauptgründe für diese Entwicklung ist die bis zum heutigen Tage nicht
nachhaltig betriebene Fischerei. Mit einer grundlegenden Reform der Gemeinsamen Fischereipolitik (GFP) im Jahre 2002 und der
Abl?sung der alten FischereigrundVO von 1993 sollten diese dr?ngenden Probleme angegangen werden. Darüber hinaus wurde mit
den Regionalbeir?ten (RACs) ein gemeinsames Forum für den Fischereisektor sowie Umweltund Verbraucherschützer geschaffen,
welches die EU-Kommission in Fischereifragen beraten soll. Leider stimmen die ersten Jahre der neuen GFP wenig zuversichtlich.
Eine Erholung der bedrohten Fischbest?nde ist vorerst nicht in Sicht, insbesondere weil die wissenschaftlichen Empfehlungen
der Fischereiexperten weiterhin ignoriert werden. Ob die neu geschaffenen RACs mit ihrer Beratungst?tigkeit und ihrem internen
Diskurs wichtige Anregungen hin zu einer nachhaltigeren Fischerei leisten k?nnen, ist zweifelhaft. 相似文献

Abstract: The paper reviews some theories of social science which could contribute to the development of a concept of European governance going beyond traditional notions, such as federal states' or 'international organisation'. The theoretical argument is based on the culturalist version of neo-institutionalism, which stresses the role of ideas in the functioning and transformation of a political order. It is claimed that both globalisation and functional differentiation transform existing nation-states and shape the emerging European polity. European governance is characterised as poly-centric and non-hierarchical. Finally, different approaches to the legitimation of such a polity are discussed. The paper comes to the conclusion that the emergence of a European political order is part of a process which could require a rethinking of basic social scientific concepts. 相似文献

Apart from collisions with road or rail vehicles and falls from height, self inflicted blunt force is a rare suicide method and mainly seen in psychiatric patients. The paper presents a rare case of suicide by active blunt force. A 68-year-old man committed suicide by repeatedly hitting his head with a stone. He sustained a craniocerebral trauma and finally died from hypothermia due to the low outdoor temperature. According to the relatives, the man was not diagnosed with a mental disorder or suicidal tendencies. Uncommon manners of self-harm are challenging for those involved in the investigation, and a differentiation between suicide, accident and homicide can only be made in synopsis of all findings. 相似文献

A method for detection and quantification of 21 benzodiazepines and the pharmacologically related "z-drugs" in human hair samples was developed and fully validated using liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS). After methanolic and methanolic/aqueous extraction, the analytes were separated using two different LC-MS systems (AB Sciex 3200 QTRAP and AB Sciex 5500 QTRAP). Separation columns, mobile phases and MS modes for both systems were: Phenomenex Kinetex, 2.6 μm, 50/2.1; 5mM ammonium formate buffer pH 3.5/methanol, total flow 0.75 mL/min; electrospray ionization (ESI), multiple reaction monitoring (MRM), information dependent acquisition (IDA), enhanced product ion scan (EPI). The assays were found to be selective for the tested compounds (alprazolam, 7-aminoclonazepam, 7-aminoflunitrazepam, bromazepam, chlordiazepoxide, clonazepam, N-desalkylflurazepam, diazepam, flunitrazepam, flurazepam, alpha-hydroxymidazolam, lorazepam, lormetazepam, midazolam, nitrazepam, nordazepam, oxazepam, phenazepam, prazepam, temazepam, triazolam, zaleplon, zolpidem and zopiclone), all validation criteria were in the required ranges according to international guidelines, except for bromazepam. Matrix effects, and process efficiencies were in the acceptable ranges evaluated using the post-extraction addition approach. Lower limits of quantification were between 0.6 and 16 pg/mg of hair. The LC-MS/MS assay has proven to be applicable for determination of the studied analytes in human hair in numerous authentic cases (n=175). 相似文献

Eyewitnesses often have to recognize the perpetrators of an observed crime from identity lineups. In the construction of these lineups, a decision must be made concerning where a suspect should be placed, but whether location in a lineup affects the identification of a perpetrator has received little attention. This study explored this problem with a face-matching task, in which observers decided if pairs of faces depict the same person or two different people (Experiment 1), and with a lineup task in which the presence of a target had to be detected in an identity parade of five faces (Experiment 2). In addition, this study also explored if high accuracy is related to a perceptual pop-out effect, whereby the target is detected rapidly among the lineup. In both experiments, observers?? eye movements revealed that location determines the order in which people were viewed, whereby faces on the left side were consistently viewed first. This location effect was reflected also in observers?? responses, so that a foil face on the left side of a lineup display was more likely to be misidentified as the target. However, identification accuracy was not related to a pop-out effect. The implications of these findings are discussed. 相似文献

While differentialists deny that non-linguistic animals can have a sense of justice, assimilationists credit some animals with such an advanced moral attitude. We approach this debate from a philosophical perspective. First, we outline the history of the notion of justice in philosophy and how various facets of that notion play a role in contemporary empirical investigations of justice among humans. On this basis, we develop a scheme for the elements of justice-relevant situations and for criteria of justice that should be fruitful in studying both humans and animals. Furthermore, we investigate the conceptual connections between a sense of justice, on the one hand, and various other mental powers, on the other, and indicate which of the latter may be beyond the ken of animals. Next, we consider recent empirical research on justice-related phenomena in animals. We argue for an intermediate position: While animals can at least in principle satisfy some preconditions of justice (intentional action, rule-following), others are problematic, notably possessing a notion of desert. A space for justice in social animals exists, yet it is rather limited compared to the rich cultures of justice in humans. Finally, we reflect on some actual or alleged implications of research on animal justice. As regards justice in humans, one should avoid a simplistic image of ??natural justice?? as boiling down to equal allocation of goods. As regards justice for animals, one should be weary of the contractualist assumption that only those capable of justice themselves are deserving of ??just?? treatment. 相似文献
