📃Scientific paper: Study of Social Networks : modeling and Analysis;Etude des Réseaux Sociaux : modélisation et analyse Abstract: Currently social networks focus on the sharing and exchange of opinions, videos, photos, music,news and others informations, one of its objectives is to establish direct and indirect linkswith users. Social networks also promote products, people (their political or artistic image) orinfluential brands.Social networks are changing rapidly, so we’re looking to see the evolution of these sharingtools, and see how social networks change over time.We have the opportunity to study the events that occur in social networks thanks to the amount ofdata they produce. In the current market there are tools that allow the analysis of social networks,but most tools are not free, and 100% free tools disappear over time. For this reason we decidedto produce computer tools able to extract and analyse the data of the social networks studied.This study begins with the state of the art, where we describe the context of the problem, thework that led to this study and a summary of the contributions made during the thesis that wepresent briefly in the rest of the abstract.i. First we focus on the geo-linguistic fingerprint and language evolution in Twitter. Accessto content of messages sent by a group of subscribers of a social network may be usedto identify and quantify some features of a group. The feature can represent the level ofinterest in an event or product, or the popularity of an idea, or of a musical hit, or of apolitical figure. The feature can also represent how language is use... Continued on ES/IODE ➡️ https://etcse.fr/UI5 ------- If you find this interesting, feel free to follow, comment and share.

📃Scientific paper: Olfaction, cognition and emotions : relationship in Alzheimer's Disease, Apathy and Covid-19;Olfaction, cognition et émotions : liens dans la maladie d'Alzheimer, l'apathie et la COVID-19 Abstract: In this thesis we created an olfactory test to measure its usefullness to detect disorders such as Alzheimer's disease or apathy syndrome or COVID-19. First, we collected the opinions of clinicians and the recommendations of experts chemists. We then selected fourteen odors, and we developed a computerized olfactory test that was able to calculate threshold and identification automatically using theses odors. We submitted a Patent for this test named "Olfactory Test for screening Alzheimer's disease ans apathy" (TODA). We cerified the interest ol TODA in everyday care practice in the diagnosis of Alzheimer's disease. Using subjects with Alzheimer's disease and healthy control subjects, both in France and Quebec, the test scores significantly differenciate AD subjects from control subjects. This test allowed cognitive monitoring of patients and highlighted odor identification regardless of culture and pathology.With a population of subjects with Minor Cognitive Disorder, with and without apathy, the results were able to significantly differenciate subjects, in particular, with a social sub-dimension of Critéria of Apathy.With subjects suffering from post-COVID-19 infection we tested with the TODA and in parallel we used the Sniffin' Stick Test, a gold standard, to verify the validity of the TODA results. The TODA also allowed us to highlight the problems identify similar odors. Finally, we also highlighted the interest of using the TODA in the case of suspected assoc...

📃Scientific paper: Acceptability of mandatory vaccination against influenza, measles, pertussis and varicella by workers in healthcare facilities: a national cross-sectional study, France, 2019 Abstract: Background Vaccination of healthcare workers (HCW) aims to protect them and to reduce transmission to susceptible patients. Influenza, measles, pertussis, and varicella vaccinations are recommended but not mandatory for HCW in France. Insufficient vaccine coverage for these diseases in HCW has raised the question of introducing mandatory vaccination. We conducted a survey to estimate acceptability of mandatory vaccination for these four vaccines by HCW working in healthcare facilities (HCF) in France, and to identify associated determinants. Methods In 2019, we performed a cross-sectional survey of physicians, nurses, midwives and nursing assistants working in HCF in France using a randomised stratified three-stage sampling design (HCF type, ward category, HCW category). Data were collected in face-to-face interviews using a tablet computer. We investigated the possible determinants of acceptability of mandatory vaccination using univariate and multivariate Poisson regressions, and estimated prevalence ratios (PR). Results A total of 8594 HCW in 167 HCF were included. For measles, pertussis, and varicella, self-reported acceptability of mandatory vaccination (very or quite favourable) was 73.1% [CI95%: 70.9–75.1], 72.1% [69.8–74.3], and 57.5% [54.5–57.7], respectively. Acceptability varied according to i) HCW and ward category for these three vaccinations, ii) age group for measles and pertussis, and iii) sex for varicella. For mandatory influenza vaccination, acc... Continued on ES/IODE ➡️ https://etcse.fr/jT2m ------- If you find this interesting, feel free to follow, comment and share.
