Culture, work attitudes, and job search:Evidence from the Swiss language border

Unemployment varies across space and in time. Can attitudes toward work explain some of these differences? We study job search durations along the Swiss language border, sharply separating Romance language speakers from German speakers. According to surveys and voting results, the language border separates two social groups with different cultural background and attitudes toward work. Despite similar local labor markets and identical institutions, Romance language speakers search for work almost seven weeks (or 22%) longer than their German speaking neighbors. This is a quantitatively large effect, comparable to a large change in unemployment insurance generosity

Loss of desiccation tolerance in Copaifera langsdorffii Desf. seeds during germination

This study evaluated the loss of desiccation tolerance in C. langsdorffii seeds during the germination process. Seeds were imbibed for 24, 48, 72, 96, 120 and 144 hours and dried to the initial moisture content, kept in this state for 3 days after which they were submitted to pre-humidification and rehydration. Ultraestructural evaluations were done aiming to observe the cell damage caused by the dry process. Desiccation tolerance was evaluated in terms of the percentage of normal seedlings. Seeds not submitted to the drying process presented 61% of normal seedlings, and after 24 hours of imbibition, followed by drying, the seeds presented the same percentage of survival. However, after 48 hours of imbibition, seeds started to lose the desiccation tolerance. There was twenty six percent of normal seedlings formed from seeds imbibed for 96 hours and later dried and rehydrated. Only 5% of seeds imbibed for 144 hours, dried and rehydrated formed normal seedlings. At 144 hours of imbibition followed the dry process, there was damage into the cell structure, indicating that the seeds were unable to keep the cell structure during the drying process. Copaifera langsdorffii seeds loses the desiccation tolerance at the start of Phase 2 of imbibition
