Perceived Opportunities for Physical Activity and Willingness to Be More Active in Older Adults with Different Physical Activity Levels

2021

This study examined equity in physical activity (PA) by investigating whether perceived opportunity for PA was associated with willingness to be more active. Among community residents (75, 80, or 85 years old, n = 962) perceived opportunity for PA (poor and good), willingness to be more active (not at all, a bit, and a lot), and level of PA (low, moderate, and high) were assessed via questionnaires. Multinomial logistic regression showed that physical activity moderated the association between poor opportunity and willingness to increase PA. Among those with moderate PA, poor opportunity for PA increased the odds of willingness to be a lot more active (multinomial odds ratio, mOR 3.90, 95% …

Prevalence of the bullying phenomenon in a schools sample of Palermo, Sicily: a pre-post intervention observational study among teachers

2018

Background and aim of the work: Bullying involves a significant percentage of school-age children. According to the latest available surveillance data, in Sicily, the estimated prevalence among 11-15 years old children is 14%. This study aimed to estimate a prevalence of the bullying phenomenon, observed by teachers, in a sample of secondary schools of Palermo, Sicily. Moreover, after the conduction of preventive interventions among teachers, aimed to evaluate any modification in bullying prevalence. Methods: A cluster sampling selection according to socio-economic level of the school neighborhood was carried out. Two anonymous online questionnaires, pre and post-intervention, were administ…

Evaluer un dispositif de formation à distance : Principes et retour d'expérience

2008

The multiplication of distance learning platforms and the complexity of some of those used within the university system raise questions. First of all, the stabilization of writing practices of digital documents. Secondly, the evaluation of these devices. We want to address this last point in this article. What is it possible to assess in this field? There are many dimensions of evaluation, depending on the angle chosen. We limit ourselves to an approach focused on evaluating the human-computer interface. The chosen testing ground is a website for law studies, developed by the University of Burgundy's further education section.

Performance of Lead-Acid Batteries with Nanostructured Electrodes at Different Temperature

2018

In this work we present innovative lead-acid batteries with nanostructured electrodes, which are cycled in a wide range of temperatures typically of lead-acid commercial batteries (EN 61427-1: 2013). In comparison to parameters usually used to commercial batteries, much more stressful conditions in terms of cut-off, charge/discharge rate and discharge were imposed.

High-Performance Lead-Acid Batteries Enabled by Pb and PbO2 Nanostructured Electrodes: Effect of Operating Temperature

2021

Lead-acid batteries are now widely used for energy storage, as result of an established and reliable technology. In the last decade, several studies have been carried out to improve the performance of this type of batteries, with the main objective to replace the conventional plates with innovative electrodes with improved stability, increased capacity and a larger active surface. Such studies ultimately aim to improve the kinetics of electrochemical conversion reactions at the electrode-solution interface and to guarantee a good electrical continuity during the repeated charge/discharge cycles. To achieve these objectives, our contribution focuses on the employment of nanostructured electr…

Entre croissance urbaine et valorisation patrimoniale : avenir agricole des Chinampas de Xochilmico (Mexique)

2009

National audience; Derniers vestiges de la culture et du savoir-faire aztèque, les Chinampas de Xochimilco sont un exemple d'agriculture traditionnelle en milieu lacustre. À proximité immédiate de Mexico, le site est aujourd'hui directement confronté à la pression urbaine et aux problèmes de pollution. Pour lutter contre la diminution des terres agricoles et la baisse des rendements, les paysans de Xochimilco ont dû s'adapter en développant de nouvelles stratégies de production. Si ces évolutions ont permis de maintenir leur activité, elles contribuent aujourd'hui à la disparition du système traditionnel de la Chinampa. Or, cette dernière est le fondement de la valorisation patrimoniale et …

Géographies sociales pour les « zones intérieures ». Des confins qui territorialisent : le cas des Sicani (Sicile)

2022

Ces dernières années, en Italie, la Stratégie Nationale pour les zones intérieures (SNAI) a encouragé les politiques de développement des territoires périphériques et ultrapériphériques italiens, définis sur la base de services essentiels en matière de santé, d’éducation et de mobilité. Cet article réfléchit sur la SNAI d’un point de vue strictement géographique : cette politique est présentée à travers quelques concepts clés de la géographie sociale italienne et française. À travers le prisme de la théorie de la territorialisation, nous lisons le SNAI comme un dispositif qui a établi des nouveaux confins et activé des processus de territorialisation. Nous réfléchissons à la fonction princ…

Associations of Work-Family Conflict with Family-Specific, Work-Specific, and Well-Being-Related Variables in a Sample of Polish and Ukrainian Adults…

2022

The conflict between work and family demands increased during the COVID-19 pandemic due to changes in lifestyle related to the lockdown. This study examines the associations between work-family conflict (WFC) and family-work conflict (FWC) with work-specific, family-specific, and well-being-related variables during the second wave of the COVID-19 pandemic. The results may be used in practice to improve the well-being of employees by adjusting home-based work and family areas of life to dynamic changes during the pandemic. The sample of 736 adults from Poland (53.26%) and Ukraine (46.74%), aged between 19 and 72 (M = 39.40; SD = 10.80), participated in the study. The cross-sectional study wa…

Bending Work Time: Curvilinear Relationship Between Working Time Dimensions and Psychological and Somatic Symptoms.

2020

Objectives Study examines the curvilinear associations of working time dimensions (working hours, time pressure, work schedules, and control of work time and pace) on psychological and somatic symptoms. Methods Representative Finnish Quality-of-Work-Life Surveys conducted in 2003, 2008 and 2013 were restricted to those (N=11,165) regularly working over 10h/week with more than one-year tenure in their job. Generalised additive models were utilised in analysis. Results Working hours had U-shaped relationships with psychosomatic symptoms, while time pressure had a threshold effect. Work pace control had linear effect. The effects of work time control and work schedules were insignificant. Ther…
