Intérêts et limites de l’electrostimulation pour l’évaluation, le traitement et la prévention des altérations neuromusculaires induites par l’exercic…
2004
L'objectif de ce travail était d'une part d'étudier les altérations neuromusculaires induites par un exercice excentrique sollicitant les muscles extenseurs du genou, et d'autre part d'étudier l'efficacité de l'électrostimulation (ES) comme moyen d'évaluation, de traitement et de prévention de ces altérations. La première étude de ce travail consistait à évaluer les contributions des mécanismes centraux et périphériques à la diminution de la contraction maximale volontaire observée après l'exercice excentrique. La fatigue basse fréquence (FBF) et la fatigue centrale expliquaient principalement la diminution du moment maximal volontaire après l'exercice excentrique. Le but de la deuxième étu…
Measuring, comparing and interpreting phenotypic selection on floral scent
2022
Natural selection on floral scent composition is a key element of the hypothesis that pollinators and other floral visitors drive scent evolution. The measure of such selection is complicated by the high-dimensional nature of floral scent data and uncertainty about the cognitive processes involved in scent-mediated communication. We use dimension reduction through reduced-rank regression to jointly estimate a scent composite trait under selection and the strength of selection acting on this trait. To assess and compare variation in selection on scent across species, time and space, we reanalyse 22 datasets on six species from four previous studies. The results agreed qualitatively with prev…
Sobre la identidad y procedencia del poeta Filóxeno y la autoría del ditirambo ???????
2019
El presente estudio pretende resolver la controversia en torno a la identidad y procedencia del poeta Filóxeno, célebre ditirambógrafo del siglo V-IV a.C. Para ello, hemos recopilado todos los testimonios que citan a personajes con el nombre de Filóxeno desde la primera mención de Aristófanes. La investigación ha revelado que existen varios individuos con el mismo nombre y rasgos comunes. No obstante, el examen de estos testimonios revela la existencia de un único autor de ditirambos: Filóxeno de Citera. Además, creemos que este poeta fue el autor del ditirambo ???????, que algunos editores atribuyeron falsamente a Filóxeno de Léucade. Posteriormente, reflexionamos sobre la identidad de Fil…
The Influence of Agricultural Support on Sale Prices of French Farmland: A Comparison of Different Subsidies, Accounting for the Role of Environmenta…
2013
In this paper, using data from individual transactions for the period 1994-2010 in the French NUTS2 region Brittany, we investigated how environmental regulations and transaction land regulations influence the price of sold plots. Regressions on three sub-samples of buyers were performed in order to assess whether different buyers have different attitude or plans regarding the farmland purchased: a sub-sample including only farmer buyers, a sub-sample including non-farmer individual buyers, and a sub-sample including non-farmer nonindividual buyers. Estimations were performed ignoring and accounting for spatial interactions (model SARAR). Results indicate that the price of land decreases wh…

CSDD 2016. gada sociālo kampaņu "Pierādi sevi citur, nevis uz ceļa!" un "Tumšo gājēju glābšanas misija" ietekme uz auditoriju
2017
Bakalaura darba tēma ir “CSDD 2016. gada sociālo kampaņu "Pierādi sevi citur, nevis uz ceļa!" un "Tumšo gājēju glābšanas misija" ietekme uz auditoriju”. Darbā tiek pētīta CSDD reklāmas kampaņu ietekme uz auditoriju. Darba mērķis ir noskaidrot, vai un kā CSDD sociālās reklāmas kampaņas, iesaistot sabiedrībā zināmus cilvēkus, izmaina sabiedrības attieksmi un uzvedību ceļu satiksmes drošības jautājumos. Darba struktūru veido trīs daļas. Teorētiskajā daļā tiek aplūkota sociālo problēmu, mārketinga, sociālā mārketinga, reklāmas un uzvedības teoriju literatūra. Metodoloģijas daļā tiek aprakstītas kvalitatīvās pētniecības metodes – reklāmas kontentanalīze un daļēji strukturēta intervija, kā arī kv…
A Path Model for Subjective Well-Being during the Second Wave of the COVID-19 Pandemic: A Comparative Study among Polish and Ukrainian University Stu…
2022
Background: Previous studies showed several associations between physical and mental health dimensions and well-being. This study aims to examine a complex path model explaining the life satisfaction of university students from Poland and Ukraine during the second wave of the COVID-19 pandemic. Methods: The cross-sectional web-based study was performed in November 2020 using Google Forms. The conventional sample of 3230 university students from Poland (n = 1581) and Ukraine (n = 1649), aged 18–59 (M = 21.40, SD = 3.46), with 59% women, participated in the study. We used standardized questionnaires to measure life satisfaction (SWLS), self-reported physical health (GSRH), perceived stress (P…
Colonoscopic screening of first-degree relatives of patients with large adenomas: increased risk of colorectal tumors.
2007
International audience; Background & Aims: The risk of developing colorectal neoplasia is not well established among family members of individuals with large adenomas and screening strategies remain under debate in this population. This study aimed at quantifying the risk of colorectal adenomas and cancers using colonoscopic screening in first-degree relatives of patients with large adenomas. Methods: This case-control study was performed in 18 endoscopic units of French non-University Hospitals. A colonoscopy was offered to first-degree relatives of 306 index cases with adenomas ≥ 10 mm, if they were alive, aged 40-75 and could be contacted by the index case. Among 674 relatives meeting th…
