Rinderwahnsinn. Können Gesellschaften aus Krisen lernen?

Bovine Spongiforme Enzephalopathie, kurz BSE, ist ein Kulminationspunkt einer Reihe sozialer Krisen: BSE ist Symbol für die Krise der Natur, die Krise des Gewissheitsanspruches der Wissenschaften, die Krise der Verwaltungen oder der Agro- und Fleischindustrie. Die BSE-Krise fordert die institutionelle Landschaft moderner Gesellschaften auf besondere Weise heraus. Aber augenscheinlich fällt es Verwaltungen und Regierungen oder einzelnen sub-politischen Akteuren wie Organisationen und Expertengemeinschaften schwer, auf das komplexe Problem zu reagieren. Die Pluralisierung von Wissensansprüchen, -ressourcen und Werthaltungen, aber auch die Zunahme von Ungewissheit und Nicht-Wissen erschweren die Chancen für eine Konvergenz der Problemsichten und die gemeinsame Organisation von Ma\nahmen zur Problemlösung. Vor diesem Hintergrund stellt sich die Frage, inwiefern Gesellschaften überhaupt aus solchen Krisen ?lernen“ können. Die jüngere modemisierungstheoretische Diskussion setzt ihre Hoffnungen dabei auf die Lerneffekte von Netzwerken wie Epistemic Communities, Advocacy- oder Diskurskoalitionen, die die kollektiven Lernchancen quer zu den üblichen Disziplin-, Organisations- und Institutionsgrenzen denken. Der folgende Beitrag versucht über diese Ansätze hinauszugehen. Dabei wird deutlich, dass die Chancen kollektiven Lernens nicht nur von den akteursspezifischen und institutionellen Problemnarrationen abhängen, sondern auch von den institutionellen Kontexten und Verfahren, durch die das Lernen des Lernens organisiert wird. Ob sich durch das Zusammenspiel von Problemnarrationen und interorganisatorischer wie interinstitutioneller Kommunikation die Lernfähigkeit in den unterschiedlichen institutionellen Feldern erhöhen lässt oder sich die Wahrscheinlichkeit ihrer Blockierung erhöht, ist eine brennende Frage.     

Evaluation of a community-based intervention to enhance road safety

A total of 300 motorists were recruited at public places to answer a self-report questionnaire on a new community-based intervention to enhance road safety. The intervention consisted of a speed-displaying device that was mounted next to the road and was visible to both motorists and the public. The device gives feedback about the current speed of the motorist. The majority of motorists believed these devices influenced compliance with the speed limit. They indicated they approached locations with these devices more slowly than similar locations without such devices. Moreover, they slowed down if they were going faster than the speed limit. They also said that their reaction to the devices was not influenced by whether they were driving in a community where they had friends or in a community where nobody knew them. These results were consistent across gender, age, levels of education, and professions.     

International Migration: Pacifier or Trigger for Military Conflicts?

Whereas the impact of trade relations on conflict has been studied extensively, this is not the case for the impact of international migration. The latter might influence the size of expected costs and benefits, and hence the likelihood of military conflict between countries. In this paper, we discuss the channels through which bilateral migration can affect the prevalence of interstate military conflict. We then estimate migration’s impact on conflict using bilateral panel data between 1960–2000. We find evidence of a positive and robust impact of South-North and South-South migration on the occurrence of conflict. These effects are even larger when we control for potential endogeneity using a GMM approach.     

Les femmes au Parlement européen: Effets du mode de scrutin,des stratégies et des ressources politiques. L'exemple de la délégation française

Cet article vise à apporter des éléments d'explication quant à la féminisation des élus français au Parlement européen. S'il semble nécessaire de prendre en compte le mode de scrutin, ses effets ne peuvent véritablement se comprendre qu'en relation, d'une part avec la position du Parlement européen dans le champ politique français et d'autre part avec la configuration propre des luttes sociales et politiques qui traversent l'espace public français au cours des années 1990. C'est dans ce cadre que le genre constitue une ressource politique plus rentable au Parlement européen qu'au parlement français, avec pour conséquence la promotion de femmes moins familiarisées avec l'exercice du métier politique; des femmes qui de ce fait s'orientent davantage vers des formes de « bonne volonté » parlementaire et des stratégies de surinvestissement des rôles politiques européens. La spécificité relative des postures qu'elles adoptent au sein de l'institution renvoie donc moins à une hypothétique « nature féminine », qu'à un ensemble de processus sociopolitiques.     

Halogenated solvent interactions with N,N-dimethyltryptamine: formation of quaternary ammonium salts and their artificially induced rearrangements during analysis

The psychoactive properties of N,N-dimethyltryptamine (DMT) 1a are known to induce altered states of consciousness in humans. This particular attribute attracts great interest from a variety of scientific and also clandestine communities. Our recent research has confirmed that DMT reacts with dichloromethane (DCM), either as a result of work-up or storage to give a quaternary N-chloromethyl ammonium salt 2a. Furthermore, this was observed to undergo rearrangement during analysis using gas chromatography-mass spectrometry (GC-MS) with products including 3-(2-chloroethyl)indole 3 and 2-methyltetrahydro-beta-carboline 4 (2-Me-THBC). This study further investigates this so far unexplored area of solvent interactions by the exposure of DMT to other halogenated solvents including dibromomethane and 1,2-dichloroethane (DCE). The N-bromomethyl- and N-chloroethyl quaternary ammonium derivatives were subsequently characterised by ion trap GC-MS in electron and chemical ionisation tandem MS mode and by NMR spectroscopy. The DCE-derived derivative formed at least six rearrangement products in the total ion chromatogram. Identification of mass spectrometry generated by-products was verified by conventional or microwave-accelerated synthesis. The use of deuterated DCM and deuterated DMT 1b provided insights into the mechanism of the rearrangements. The presence of potentially characteristic marker molecules may allow the identification of solvents used during the manufacture of controlled substances, which is often neglected since these are considered inert.     

The detection of simulated amnesia

Claims of amnesia are frequently raised in criminal and civil cases. There is a consensus in the legal community that amnesia is easily faked and practically impossible to disprove, and that many who claim to be amnesic are malingering. The present studies compared, on a variety of memory tasks, subjects instructed to simulate amnesia with subjects who had memory impairments due to brain damage. The simulators displayed patterns of performance different from those of memory-impaired subjects. These results suggest that lay-people have inaccurate beliefs about the cognitive features of amnesia, and do not distinguish among etiologically distinct amnestic disorders. Tasks that exploit lay-people's inaccurate beliefs about amnesia appear promising for the detection of malingering.     

Juvenile sex offenders in a Dutch mandatory educational programme: Subtypes and characteristics

Abstract

Significant differences between subgroups of juvenile sex offenders (JSOs) are found in both Dutch and international research. Most of this literature represents the more delinquent and more disturbed sections of the population of JSOs. This paper describes the characteristics of 302 less disturbed and less violent JSOs in a mandatory educational programme. Characteristics of exhibitionists (n=26), child molesters (n=39) and peer offenders (n=237) are compared. Peer offenders are subdivided into solo offenders (n=90) and group offenders (n=142). Variables are: demographics, family background, psychosocial functioning, offence characteristics and victim characteristics. Significant differences are found in a large number of variables, supporting findings from earlier research in clinical samples. Differences between subgroups are largest between group-offending peer offenders, on one hand, and exhibitionists and child molesters on the other hand. The majority of our sample seems to have an ordinary background and shows no apparent sign of psychosocial dysfunction. The clinical and theoretical relevance of the results is discussed.     

Game fences in the Karoo: reconfiguring spatial and social relations

In this article, we discuss how farm conversions to wildlife habitats result in the reconfiguration of spatial and social relations on white-owned commercial farms in the Karoo region of the Eastern Cape in South Africa. Farmers and landowners justify such conversions stressing economic and ecological rationales. We illustrate how conversions are (also) a reaction to post-apartheid land reform and labour legislation policies, which white farmers and landowners perceive as a serious threat. They seek to legitimate their position in society and reassert their place on the land by claiming a new role as nature conservationists. We argue that game farms should be interpreted as economically and politically contested spaces for three reasons: (1) whereas landowners present the farm workers' displacement from game farms as the unintended by-product of a changing rural economy, the creation of ‘pristine’ wilderness seems designed to empty the land of farm dwellers who may lay claim to the land; (2) game farms further disconnect the historically developed links between farm dwellers and farms, denying them a place of residence and a base for multiple livelihood strategies; (3) this way the conversion process deepens farm dwellers' experiences of dispossession and challenges their sense of belonging. Game fences effectively define farm workers and dwellers as people out of place. These dynamics contrast government reform policies aimed at addressing historical injustices and protecting farm dwellers' tenure security.
