  • Understanding the molecular structure of life in the early 20th century. A scientific biography of Henri Devaux (1862-1956) : A scientific biography of Henri Devaux (1862-1956)
    2020
    Co-Authors: Le Roux Benjamin
    Abstract:

    Formé auprès de Gaston Bonnier (1853-1922) à Paris à la fin des années 1880, Henri Devaux (1862-1956) s’impose comme l’un des botanistes prometteurs de sa génération en travaillant sur les échanges gazeux chez les plantes aquatiques. De 1906 à 1932, il occupe la chaire de physiologie végétale de la Faculté des Sciences de Bordeaux. Bien que ce ne soit pas son domaine de prédilection, il s’intéresse progressivement à la physico-chimie des lames (ou couches) minces et devient l’une des figures de l’école française qui émerge dans les années 1910 autour de ces questions. Tout au long du premier tiers du XXe siècle, ses travaux sur les effets de surface vont faire autorité, y compris outre-Atlantique, et lui ouvrir les portes de l’Académie des Sciences. Les lames minces sont aussi un moyen pour lui de comprendre la structure et le fonctionnement des membranes cellulaires et in fine ceux du vivant à l’échelle moléculaire. En nous appuyant sur près de 10 000 pages de notes de laboratoire inédites, nous avons reconstruit l’essentiel de son cheminement intellectuel dans ce domaine.Ancré dans la foi réformée, Devaux cherche par ailleurs à montrer dans des écrits de vulgarisation que les savoirs scientifiques et la Bible concordent. Il y défend notamment une vision créationniste et fixiste du monde. Devaux lie régulièrement Science et religion dans ses carnets de laboratoire et affirme même sa foi dans un article du Journal de physique.Trained by Gaston Bonnier (1853-1922) in Paris at the end of the 1880s, Henri Devaux (1862-1956) was numbered among the most promising botanists of his generation due to his work on gaseous exchanges of aquatic plants. Between 1906 and 1932, he was professor of plant physiology at the Faculty of Sciences of Bordeaux. Even though it was not his primary field of study, he slowly developed an interest in the physico-chemistry of thin films (or layers) and became one of the most prominent figures of the French school that emerged on this topic in the 1910s. Throughout the first third of the 20th century, his works on surface were considered as a reference in this field, also in the United States, and opened him the doors of the Académie des Sciences. Thin layers were also for him a way to understand the structure and functions of cellular membranes and, consequently, of the life on the molecular scale. Having worked on almost 10 000 pages of his unexplored laboratory notebooks, we have reconstructed the salient points of his investigative pathway in this field.Rooted in a protestant faith, Devaux also tried to show with Science Popularization writings that scientific knowledge and the Bible are in harmony. He defended a fixist creationist vision of the world. Devaux regularly linked Science and religion in his laboratory notebooks and even claimed his faith in an article published in the Journal de physique

  • netizens food safety knowledge attitude behaviors and demand for Science Popularization by wemedia
    International Journal of Environmental Research and Public Health, 2020
    Co-Authors: Yong Zhao, Yangxue Xiao, Zhengjie Cai, Xinmiao Luo, Fan Zhang
    Abstract:

    This study aimed to investigate netizens' food safety knowledge, attitudes and behavior, status, and their demand for Science Popularization by WeMedia. Firstly, participants were recruited by WeMedia, including WeChat, Microblog, and QQ. Then, a web-based survey was conducted using a self-designed questionnaire, which comprised 29 items about the knowledge, attitude, and practice (KAP) status of netizens' food safety and the demand for Science Popularization by WeMedia. A correct answer on knowledge-related items was assigned a value of 1 point, and the high, medium, and low levels of knowledge had a total of 6-8, 3-5, and 0-2 points, respectively. A correct answer on attitude-related items was given a value of 1 to 5 points, and the high, medium, and low levels of attitude had a total of 16-20, 8-16, and l4-8 points, respectively. A correct answer on practice-related items was given a value of 5 to 1 point, and the high, medium, and low levels of attitude had a total of 22-30, 14-22, and 6-14 points, respectively. Results showed that the distribution of the different levels of the KAP scores were as follows: high (79.0%), medium (20.2%), low (0.8%); high (65.6%), medium (34.1%), low (0.3%); high (70.1%), medium (29.4%), low (0.5%). Approximately 86% of the subjects desired to obtain food safety knowledge from WeMedia. In conclusion, the netizens' KAP in food safety are relatively optimistic. A large demand for Science Popularization on food safety knowledge by WeMedia is warranted. The WeMedia has a potentially important role in Science Popularization and health promotion related to food safety and health behaviors.
