Grauzonen : Funktionsweisen der Beniner Polizei und ihr Verhältnis zur Bevölkerung /// Arbeitspapiere / Institut für Ethnologie und Afrikastudien ; 133

Gewalttätig, korrupt und faul oder eher gesetzestreu, hilfsbereit und freundlich? Diese Abhandlung befasst sich mit der Arbeitsweise der Beniner Polizei und den Bildern, die sie von sich erzeugt und den Eindrücken, die sie bei den Bürgern hinterlässt. Die Arbeit liefert Erkenntnisse über den Aufbau und die Arbeitsweise der Beniner Polizei. Sie verweist auch auf das Konkurrenzverhältnis der Polizei zu anderen Sicherheitskräften, wie etwa der Gendarmerie und sie zeigt, dass sich die Polizeirnin diversen Grauzonen – der Legalität, der Staatlichkeit und der Formalität – bewegt. Informelle Strategien, schleichende Privatisierung und Korruption sichern in einem gewissen Rahmen das Funktionieren der Institution. Diese Schwächen der Institution haben jedoch negative Auswirkungen auf das Bild der Polizei und ihr Verhältnis zu den Bürgern. Nicht das propagierte Ideal einer Polizei, sondern die realen Interaktionen mit ihr dominieren die Wahrnehmung der Bürger von der Organisation.

Keratin 8 sequence variants in patients with pancreatitis and pancreatic cancer

Keratin 8 (KRT8) is one of the major intermediate filament proteins expressed in single-layered epithelia of the gastrointestinal tract. Transgenic mice over-expressing human KRT8 display pancreatic mononuclear infiltration, interstitial fibrosis and dysplasia of acinar cells resulting in exocrine pancreatic insufficiency. These experimental data are in accordance with a recent report describing an association between KRT8 variations and chronic pancreatitis. This prompted us to investigate KRT8 polymorphisms in patients with pancreatic disorders. The KRT8 Y54H and G62C polymorphisms were assessed in a cohort of patients with acute and chronic pancreatitis of various aetiologies or pancreatic cancer originating from Austria (n=16), the Czech Republic (n=90), Germany (n=1698), Great Britain (n=36), India (n=60), Italy (n=143), the Netherlands (n=128), Romania (n=3), Spain (n=133), and Switzerland (n=129). We also studied 4,234 control subjects from these countries and 1,492 control subjects originating from Benin, Cameroon, Ethiopia, Ecuador, and Turkey. Polymorphisms were analysed by melting curve analysis with fluorescence resonance energy transfer probes. The frequency of G62C did not differ between patients with acute or chronic pancreatitis, pancreatic adenocarcinoma and control individuals. The frequency of G62C varied in European populations from 0.4 to 3.8%, showing a northwest to southeast decline. The Y54H alteration was not detected in any of the 2,436 patients. Only 3/4,580 (0.07%) European, Turkish and Indian control subjects were heterozygous for Y54H in contrast to 34/951 (3.6%) control subjects of African descent. Our data suggest that the KRT8 alterations, Y54H and G62C, do not predispose patients to the development of pancreatitis or pancreatic cancer.

A synchronic lexical study of the Ede language continuum of West Africa: The effects of different similarity judgment criteria

In the context of a synchronic lexical study of the Ede varieties of West Africa, this paper investigates whether the use of different criteria sets to judge the similarity of lexical features in different language varieties yields matching conclusions regarding the relative relationships and clustering of the investigated varieties and thus leads to similar recommendations for further sociolinguistic research. Word lists elicited in 28 Ede varieties were analyzed with the inspection method. To explore the effects of different similarity judgment criteria, two different similarity judgment criteria sets were applied to the elicited data to identify similar lexical items. The quantification of these similarity decisions led to the computation of two similarity matrices which were subsequently analyzed by means of correlation analysis and multidimensional scaling. The findings of this analysis suggest compatible conclusions regarding the relative relationships and clustering of the investigated Ede varieties. However, the matching clustering results do not necessarily lead to the same recommendations for more in-depth sociolinguistic research, when interpreted in terms of an absolute lexical similarity threshold. The indicated ambiguities suggest the usefulness of focusing on the relative, rather than absolute in establishing recommendations for further sociolinguistic research.
