Citizenship education in Switzerland before, during and after the First World War

Citizenship education was intensively discussed during the 1910s. Patriotic ideals and the love of the fatherland were described with diligence in teachers' journals. After the outbreak of the World War I, Swiss teachers reacted immediately to the new circumstances and published lessons in their weekly teacher journals for every day of school for different grade levels. These lessons comprised current events and civic education as well as didactical instructions for the teacher. In pupils' essays, citizens are often depicted as religious members of society who are industrious and hardworking, whereas in the journals, religious aspects are related to peace but not to citizenship education. As a multilingual and neutral country, Switzerland struggled with major domestic problems due to the cultural conflict between the French- and the German-speaking regions, especially during wartime. However, teachers promoted unity from the beginning. Therefore, changes and continuities during this decade concerning citizenship education are of crucial research interest. The practical sections of teachers' journals, including lessons and didactical instructions, and pupils' essays provide insight into what happened in the classrooms. Which forms of national identity and citizenship were taught in classrooms before, during and shortly after WW1 in public schools in Switzerland? How did pupils describe the current issues of war and citizenship?

Vitamin E intake from natural sources and head and neck cancer risk : a pooled analysis in the International Head and Neck Cancer Epidemiology consortium.

BACKGROUND: Evidence for the possible effect of vitamin E on head and neck cancers (HNCs) is limited. METHODS: We used individual-level pooled data from 10 case-control studies (5959 cases and 12 248 controls) participating in the International Head and Neck Cancer Epidemiology (INHANCE) consortium to assess the association between vitamin E intake from natural sources and cancer of the oral cavity/pharynx and larynx. Adjusted odds ratios (ORs) and 95% confidence intervals (CIs) were estimated using unconditional logistic regression models applied to quintile categories of nonalcohol energy-adjusted vitamin E intake. RESULTS: Intake of vitamin E was inversely related to oral/pharyngeal cancer (OR for the fifth vs the first quintile category=0.59, 95% CI: 0.49-0.71; P for trend <0.001) and to laryngeal cancer (OR=0.67, 95% CI: 0.54-0.83, P for trend <0.001). There was, however, appreciable heterogeneity of the estimated effect across studies for oral/pharyngeal cancer. Inverse associations were generally observed for the anatomical subsites of oral and pharyngeal cancer and within covariate strata for both sites. CONCLUSION: Our findings suggest that greater vitamin E intake from foods may lower HNC risk, although we were not able to explain the heterogeneity observed across studies or rule out certain sources of bias.

Reply to 'Sources of uncertainties in cod distribution models'

Ingvaldsen et al. comment on our study assessing global fish interchanges between the North Atlantic and Pacific oceans for more than 500 species during the entire 21st century. They propose that discrepancies between our model projections and observed data for cod in the Barents Sea are the result of the choice of Atmosphere-Ocean General Circulation Models (AOGCMs). We address this assertion here, re-running the cod model with additional observation data from the Barents Sea1, 3, and show that the lack of open-access, archived data for the Barents Sea was the primary cause of local prediction mismatch. This finding recalls the importance of systematic deposit of biodiversity data in global databases
