Überlegungen zum Berner Stichprobenplan

Fritschi, Meyer und Schweizer haben vor drei Jahrzehnten in der Schweizerischen Zeitschrift für Soziologie ein elegantes Stichprobenverfahren für ein gesamtschweizerisches Sample vorgeschlagen, bei dem die Befragungspersonen mit Hilfe kommunaler Wahl- oder Einwohnerregister bestimmt werden. Ungeachtet der Vorzüge dieser Methode beruhen heute die meisten Bevölkerungsumfragen in der Schweiz aber auf Telefonregisterstichproben, die bezüglich der Abdeckung der Grundgesamtheit als problematisch anzusehen sind. Sozusagen als Wiederbelebungsversuch möchte ich deshalb hier einige Überlegungen zum Stichprobenplan von Fritschi et al. präsentieren. Die theoretischen Eigenschaften des Stichprobenplans werden besprochen und ein vereinfachtes Verfahren, die ex ante geteilte Stichprobe, wird vorgeschlagen. Mit Hilfe einer Simulationsstudie werden sodann die Vorzüge des "Berner Stichprobenplans" gegenüber einer einfachen Klumpenstichprobe illustriert.

Laparoscopic management of bowel endometriosis: resection margins as a predictor of recurrence.

OBJECTIVE To evaluate possible predictive factors for recurrence after laparoscopic segmental bowel resection for bowel endometriosis. DESIGN Cohort study. SETTING Academic tertiary referral center. METHODS 95 symptomatic women with bowel endometriosis who underwent laparoscopic segmental bowel resection at the Endometriosis clinic, University of Berne, between 2002 and 2012 were enrolled. Since 14 women were lost to follow-up, 81 formed the final cohort. Clinical and histological characteristics were examined as possible predictive factors for disease recurrence. MAIN OUTCOME MEASURES Recurrence, defined as a subsequent operation due to recurrent endometriosis-associated pain with a histologically confirmed endometriotic lesion. RESULTS Recurrence was observed in 13 (16%) patients. Variables that were significantly associated to recurrence by the Cox regression analysis were positive bowel resection margins (hazard ratio 6.5, 95% confidence interval 1.8-23.5, p = 0.005), age <31 years (hazard ratio 5.6, 95% confidence interval 1.7-18.6, p = 0.005) and body mass index ≥23 kg/m(2) (hazard ratio 11.0, 95% confidence interval 2.7-44.6, p = 0.001). CONCLUSIONS Positive bowel resection margins as well as age <31 years and body mass index ≥23 kg/m(2) appear to be independent predictors of disease recurrence.

NakInfo online: Developer's manual

The Local Urban Observatory in Nakuru (LUO, Kenya 2003) has developed a progressive and to date unique electronic information service called NakInfo. The objective of LUO is to make residents aware of public services delivery by their Local Authority, in this case the Municipal Council of Nakuru, and give them a voice in achieving improved quality of life. NakInfo facilitates community participation in local government business and demonstrates how to implement such participation in a developing country. The LUO project was formally initiated by the Municipal Council of Nakuru in January 2003, in collaboration with the Centre for Development and Environment (CDE) of the University of Berne (Switzerland) with funding from the Swiss Agency for Development and Cooperation (SDC).

Milan Kundera et la littérature mondiale

« Les littératures nationales ne signifient plus grand-chose aujourd’hui. Nous entrons dans l’ère de la littérature mondiale et il appartient à chacun de nous de hâter cette évolution » (Goethe). Milan Kundera, écrivain natif de Moravie ayant émigré en France en 1975, reprend à son compte cet idéal formulé en 1827 par Goethe et le réactive : selon lui, en effet, le seul contexte où peuvent véritablement se révéler le sens et la valeur d’une œuvre est le grand contexte de l’histoire supranationale. Dans cet espace de diversité où l’œuvre n’est pas soutenue par son prestige national, mais par son originalité, un roman tchèque (littérature d’une petite nation) aussi bien qu’un roman français (littérature d’une grande nation) peut trouver sa place. Comment faire une histoire de la littérature mondiale sans la présenter comme une juxtaposition d’histoires littéraires nationales ? C’est la question à laquelle cette conférence s’efforcera de répondre en s’appuyant sur les réflexions culturelles aussi bien que politiques de Milan Kundera.

Linking Applied Ethnobotany to Social Learning: A Participatory Tool for the Promotion of Indigenous Plants Use in Matutuíne, Southern Mozambique

In its search for pathways towards a more sustainable management of natural resources, development oriented research increasingly faces the challenge to develop new concepts and tools based on transdisciplinarity. Transdisciplinarity can, in terms of an idealized goal, be defined as a research approach that identifies and solves problems not only independently of disciplinary boundaries, but also including the knowledge and perceptions of non-scientific actors in a participatory process. In Mozambique, the Centre for Development and Environment (Berne, Switzerland), in partnership with Impacto and Helvetas (Maputo, Mozambique), has elaborated a new transdisciplinary tool to identify indigenous plants with a potential for commercialization. The tool combines methods from applied ethnobotany with participatory research in a social learning process. This approach was devised to support a development project aimed at creating alternative sources of income for rural communities of Matutuíne district, Southern Mozambique, while reducing the pressure on the natural environment. The methodology, which has been applied and tested, is innovative in that it combines important data collection through participatory research with a social learning process involving both local and external actors. This mutual learning process provides a space for complementary forms of knowledge to meet, eventually leading to the adoption of an integrated approach to natural resource management with an understanding of its ecological, socio-economic and cultural aspects; local stakeholders are included in the identification of potentials for sustainable development. Sustainable development itself, as a normative concept, can only be defined through social learning and consensus building between the local and external stakeholders.
