The recent conflict in the Sahel area is another case where the nexus of terrorism and organized crime causes challenges to the international community. Comparing the situation with that of the Andean region brings forth the challenges faced when dealing with this type of conflict: the states’ weak presence in the remote regions, the insurgents’ ability to offer income and “security” to the people, immediate threat to international investments, unresolved political/regional issues, the marriage of convenience of insurgents/terrorists and organized crime, internal divisions of the insurgent groups and also ideologies surviving or suffering after the elimination of their leaders.  相似文献

Zusammenfassung Mit Urteil vom 29. Oktober 2007 hat das Amtsgericht Hannover einen Angler wegen Versto?es gegen § 17 Nr. 2 b des Tierschutzgesetz (TierSchG) zu einer Geldstrafe in H?he von 15 Tagess?tzen verurteilt. Nach den Feststellungen des Gerichts hatte der Angeklagte am 16.11.2007 sechzig Rotfedern zum Zwecke der Verwendung als K?derfische in einem insgesamt zehn Liter fassenden, jedoch zeitweise lediglich mit sieben Litern Wasser gefüllten ovalf?rmigen Eimer zur weiteren Verwendung zwischengeh?ltert. Im Verlauf der H?lterung schwammen einige der Fische an die Oberfl?che, woraus das Gericht auf einen zwischenzeitlichen Sauerstoffmangel im Beh?ltnis schloss. Nach Auffassung des AG Hannover stellt das Verhalten des Anglers insgesamt einen Versto? gegen § 17 TierSchG in der Modalit?t des Zufügens von l?nger anhaltenden erheblichen Leiden nach Nr. 2 b dar.  相似文献

Seit dem 7. 9. 2004 liegt ein weiteres Urteil des EuGH zum europäischen Abfallbegriff vor. Danach ist Benzin, das unbeabsichtigt in den Boden und das Grundwasser gelangt, ebenso als Abfall zu qualifizieren wie das verunreinigte Erdreich selbst. Nach Ansicht des Gerichtshofs spielt es dabei keine Rolle, ob der Boden nach der Verschmutzung ausgehoben worden ist oder nicht. Diese Rechtsprechung steht nicht länger im Einklang mit der ständigen Rechtsprechung deutscher Gerichte und wirft insbesondere mit Blick auf die fehlende Sonderrechtsfähigkeit nicht ausgehobenen kontaminierten Erdreichs Fragen auf, denen im folgenden Beitrag nachgegangen werden soll.  相似文献

Purpose. In police interviews children may be asked the same question many times. We investigated how the number of repetitions and the interval between those repetitions affected the accuracy and consistency of children's responses. Methods. 156 children aged 4–9 years watched a staged event and were interviewed individually 1 week later. Children were asked eight open‐ended questions, which were each repeated a further four times (making a total of forty questions). Half these open‐ended questions could be answered from information in the event, and half were unanswerable (so children should have said ‘don't know’ in response to these questions). The questions were repeated in gist form. The interval between an initial question and its repetitions was varied by use of other questions and twenty non‐repeated filler questions. The intervals between repetitions were immediate repetition, repetition after a delay of three intervening questions, after a delay of six intervening questions, and after ten or more intervening questions. Results. Over a quarter of children's responses to repeated questions changed, usually resulting in a decline in accuracy, particularly after the first repetition. Subsequently, the number of repetitions and delay interval had little effect on responses to answerable questions although accuracy to unanswerable questions continued to decline. Conclusions. Question repetition had a negative affect on children's consistency and accuracy. For unanswerable questions in particular, the more often a question was repeated the more likely children were to invent a response.  相似文献

Public-goods dilemmas are characterized by conflicts between self-interest and the welfare of a group or society at large. Research has identified several factors that enhance cooperation in such dilemmas. However, less is known about how concern for distributive justice affects willingness to contribute in asymmetric public-goods dilemmas. To test the hypothesis that contributions to a common resource is related to perceived fairness, experiments were performed to investigate willingness to pay to the social service of child care in hypothetical societies. Experiment 1 aimed at replicating a previous survey study (Biel et al., 1997). Experiments 2 and 3 were extensions. In all three experiments subjects were asked to indicate how fair they considered different distributions of the quality of child care provided by their municipality. These distributions corresponded to the principles of equality, equity, and need. University students (32, 48, and 32 in the three experiments, respectively) served as subjects. Ratings of perceived fairness were positively related to willingness to pay. Other factors also positively related to willingness to pay included ability to pay, personal need, expected payment from others, and the number of households who had to contribute in order to maintain the quality. Furthermore, decreasing municipality size increased willingness to pay.  相似文献

In this article, I examine some of the interactions between the crisis in Darfur and Chad through its increasingly complicated ethnic threads and explain how Chad slid back into authoritarianism in 2004. Factionalism broke down the mesh of ethnic politics into personalised rule and allegiances. The international response to the crisis in Darfur allowed the Chadian leadership to reinforce its position in the country. Ever since, a precarious equilibrium set in. Déby has become the longest-serving president in the history of modern Chad. Previously weakened by interfactional agreements and oil wealth expectations and then by the crisis in Darfur, the regime re-established internal and external means for preserving the status quo. Yet appearances can be deceiving. The argument is based on fieldwork and secondary literature.  相似文献
