L'ordinateur, outil de productivité de l'enseignant quelle formation initiale en IUFM ?

1992

Les nouvelles technologies de l'information et de la communication – audiovisuel, informatique et télématique – ont connu depuis trente ans en France de grandes actions de mise en oeuvre dans l'enseignement : radio-télévision scolaire, Jeune Téléspectateur Actif, expérimentation « 58 lycées », plan « 10 000 micros », expérimentation « 84 collèges », plan « 100 000 micros », plan IPT, opération « vidéo collège »...Les avancées technologiques de ces dernières années ont favorisé l'évolution des pratiques pédagogiques des enseignants. On est passé progressivement de pratiques indépendantes et isolées de l'informatique, de la télématique et de l'audio visuel à une utilisation combinée qui conce…

Altered EEG Oscillatory Brain Networks During Music-Listening in Major Depression

2021

To examine the electrophysiological underpinnings of the functional networks involved in music listening, previous approaches based on spatial independent component analysis (ICA) have recently been used to ongoing electroencephalography (EEG) and magnetoencephalography (MEG). However, those studies focused on healthy subjects, and failed to examine the group-level comparisons during music listening. Here, we combined group-level spatial Fourier ICA with acoustic feature extraction, to enable group comparisons in frequency-specific brain networks of musical feature processing. It was then applied to healthy subjects and subjects with major depressive disorder (MDD). The music-induced oscil…

Monitoring a meat-free pledge with smartphones:An experimental study

2020

Pledges are a popular strategy to encourage meat reduction, though experimental studies of their efficacy are lacking. Three-hundred and twenty-five participants from three different countries (UK, Germany, Australia) were randomly assigned to pledge 28 days meat-free or not, and their behavior was tracked via smartphones. Participants answered daily surveys regarding their eating behavior, meat cravings, and shared photos of their meals. Baseline data was collected prior to the pledge, after the 28 days, and one-month post-intervention. Participants assigned to the pledge condition ate less meat across the 28 days, compared to control participants. Meat reductions, observed at outtake, did…

Strategic agility explanations for managing franchising expansion during economic cycles

2017

Purpose This paper aims to demonstrate how franchising firms can manage system expansion by weathering the economic effects of a location (i.e. country-level economic cycles) by shifting their resources. Design/methodology/approach The authors use a comprehensive database of 151 US hybrid franchising organizations, including observations for the years between 2001 and 2008. Data analysis is conducted with count model panel data with a Poisson distribution. Findings The model reveals a curvilinear U-shaped relationship between location (i.e. economic cycles) and franchising expansion. Originality/value This study contributes to competitiveness literature by showing how franchising firms res…

Profit Sharing the Firm-Size Wage Premium

2017

This study analyzes the relationships among wages, firm size, and profit sharing schemes. We develop a simple theoretical model and explore the relationship empirically using high-quality panel data. The theoretical model shows that the firm-size wage premium decreases in the presence of profit sharing. The empirical results based on rich matched employee-employer data for private sector wage earners in Finland show that the firm-size wage premium is modest, and it becomes negligible when we account for profit sharing and covariates describing assortative matching and monopsony behavior. The analysis suggests that profit sharing schemes embody effects of firm-specific unobservables that rai…

Dissimilar Regulation of Antimicrobial Proteins in the Midgut of Spodoptera exigua Larvae Challenged with Bacillus thuringiensis Toxins or Baculoviru…

2015

Antimicrobial peptides (AMPs) and lysozymes are the main effectors of the insect immune system, and they are involved in both local and systemic responses. Among local responses, midgut immune reaction plays an important role in fighting pathogens that reach the insect body through the oral route, as do many microorganisms used in pest control. Under this point of view, understanding how insects defend themselves locally during the first phases of infections caused by food-borne pathogens is important to further improve microbial control strategies. In the present study, we analyzed the transcriptional response of AMPs and lysozymes in the midgut of Spodoptera exigua (Lepidoptera: Noctuidae…

Persistence and turnover in regional unemployment disparities

1998

PEHKONEN J. and TERVO H. (1998) Reg. Studies, 32 , 445-458, Persistence and turnover in regional unemployment disparities. This study investigates persistence and turnover in regional unemployment disparities in Finland by examining time-series data on 10 labour districts and 423 municipalities. The data on the labour districts indicates that regional unemployment disparities are rather persistent and that steady-state unemployment rates differ considerably across the districts. The results on the municipality level data, however, suggest the presence of substantial intra-distribution dynamics and that the degree of persistence is less profound than the labour district data indicates. In al…

Plant-herbivorous beetle networks : molecular characterization of trophic ecology within a threatened steppic environment

2015

DNA barcoding facilitates many evolutionary and ecological studies, including the examination of the dietary diversity of herbivores. In this study, we present a survey of ecological associations between herbivorous beetles and host plants from seriously threatened European steppic grasslands. We determined host plants for the majority (65%) of steppic leaf beetles (55 species) and weevils (59) known from central Europe using two barcodes (trnL and rbcL) and two sequencing strategies (Sanger for mono/oligophagous species and Illumina for polyphagous taxa). To better understand the ecological associations between steppic beetles and their host plants, we tested the hypothesis that leaf beetl…
