摘要： In the context of increasing urbanization, preserving urban biodiversity has become a priority because biodiversity appears to be a key element when evaluating the well-being of urban residents. Recently, urban management has relied on a 'renaturing' strategy to improve biodiversity, but the benefits of these policies remain debated. In this study, we evaluated the effects of urban land use and green corridors on (1) urban avian biodiversity, and (2) the presence of the most common (top 70%) and least common (bottom 30%) bird species. We surveyed bird diversity at 102 sites during the Spring in a small French city, and performed a PCA on several habitat structures (e.g. roads, houses, grassy areas) to determine the level of urbanization of each site. Then, we tested with GLMMs the effects of land use (PC1), distance to the edge of the city, and distance to the corridor on bird diversity. We found a positive effect of green infrastructures on bird species richness, and this effect was reinforced by the proximity to the green corridor. Thus, bird species richness and the presence of common species were positively impacted by the presence of green areas, the proximity to the city edge and the proximity to the green corridor. The presence of the green corridor contributed significantly to the presence of rare species, which emphasizes its role in promoting avian biodiversity. Green corridors are a key element of the urban landscape because they allow less common species to colonize cities, and thus enhance urban biodiversity.

摘要： 法语是近几年来高校最热门的小语种之一。随着中国高校教育改革,越来越多的高校致力于培养多元化的应用型人才。本课程运用创新教学模式,通过让学生自己观察、发现并总结的方法,摒弃了传统教学法中“教师讲-学生记”这样枯燥的且效果较差教学模式,锻炼学生自主思考、总结的能力,并通过课堂小游戏的方式让学生快速并牢固地记忆语法点,独立思考和小组交流都能紧抓学生的注意力。此种创新教学方式,弱化了课堂上教师的角色,从而达到学生为主,教师为辅的教学效果。

关键词： 后疫情时期   “双线混融教学”   基础法语  

摘要： 2020年新型冠状病毒肺炎疫情使高校传统的教学组织形式发生改变,近4个月的线上教学凸显出众多优点,随着疫情形势逐渐缓和,虽然线下教学陆续恢复,但教学模式无法完全回到以前,改革势在必行。后疫情时代,“双线混融教学”模式的探索与实践是大势所趋,这种探索与实践对今后高校教学模式及教学机制的改革有重大的启示意义。本文以“基础法语(CF)”课程自身特点为基础,从课程内容、教学过程与师生关系三方面对线上教学的优势与不足展开分析,同时将线上教学与线下教学进行比较,发现问题,提出解决措施,归纳总结如何真正做到线上、线下教学的融会贯通与双线共生,以期为后疫情时代高校教学实践的顺利开展及教学模式的改革提供参考。

摘要： The effects of radiofrequency exposure on the health of people living near mobile-phone base stations (MPBSs) have been the subject of several studies since the mid-2000s, with contradictory results. We aimed to investigate the association between measured exposure to radiofrequency electromagnetic fields (RF-EMF) from MPBSs and the presence of self-reported non-specific and insomnia-like symptoms. A cross-sectional survey conducted between 2015 and 2017 in five large cities in France involved 354 people living in buildings located at a distance of 250 m or less from an MPBS and in the main transmit beam of the antennas. Information on environmental concerns, anxiety, and non-specific and insomnia-like symptoms was collected with a questionnaire administrated by telephone. A complete broadband field-meter measurement [100 kHz 6 GHz] was then made at five points of each dwelling, followed by a spectral analysis at the point of highest exposure, detailing the contribution of each service, including MPBS. The median exposure from MPBS was 0.27 V/m (0.44 V/m for global field), ranging from 0.03 V/m to 3.58 V/m, MPBSs being the main source of exposure for 64% of the dwellings. In this study population, the measured exposure from MPBSs was not associated with self-reported non-specific or insomnia-like symptoms. However, for insomnia-like symptoms, a significant interaction was found between RF-EMF exposure from MPBSs and environmental concerns. These findings do not support the hypothesis of an effect of RF-EMF from MPBSs on non-specific or insomnia like symptoms in the overall population. Studies are needed to further investigate the positive association observed between exposure from MPBSs and insomnia-like symptoms among people reporting environmental concerns.

摘要： Accurate demographic knowledge of the equine population is needed to assess and model equine health events. France is one of the few European countries with an operational centralized database (SIRE) recording individual data on all declared equines living in France and on their owners and keepers. Our study aimed to assess SIRE database quality concerning the updating of information by equine owners and keepers with a view to its improvement and use in surveillance and research. Two online surveys were conducted with the participation of 6244 registered keepers and 13,869 owners. Results showed some inconsistencies between SIRE records and survey responses. The inconsistency rate for equines whose castration and death were not registered in the database was 28.7% and 5.9% respectively. Concerning owners, 11% of respondents did not own the reference equine selected considered by the survey, 33% had changed address without updating it in the SIRE. Concerning premises hosting equines, the keeper survey's inconsistency rate was 7.3%, of which 57 respondents had closed and 32 had opened premises without reporting it. Comparatively, the owner survey's inconsistency rate was 40.7% including respondents who owned and hosted an equine without reporting these equine premises, and owners who did not keep any equines on their premises. In conclusion, the SIRE database proved to be a valuable and reliable source for epidemiological research as long as some bias is taken into account. On the contrary, its use in surveillance is currently limited due some shortcomings in updating and/or reporting by owners and keepers.
