Culture-level dimensions of social axioms and their correlates across 41 cultures

2004

Leung and colleagues have revealed a five-dimensional structure of social axioms across individuals from five cultural groups. The present research was designed to reveal the culture level factor structure of social axioms and its correlates across 41 nations. An ecological factor analysis on the 60 items of the Social Axioms Survey extracted two factors: Dynamic Externality correlates with value measures tapping collectivism, hierarchy, and conservatism and with national indices indicative of lower social development. Societal Cynicism is less strongly and broadly correlated with previous values measures or other national indices and seems to define a novel cultural syndrome. Its national …

The Diapause Lipidomes of Three Closely Related Beetle Species Reveal Mechanisms for Tolerating Energetic and Cold Stress in High-Latitude Seasonal E…

2020

During winter insects face energetic stress driven by lack of food, and thermal stress due to sub-optimal and even lethal temperatures. To survive, most insects living in seasonal environments such as high latitudes, enter diapause, a deep resting stage characterized by a cessation of development, metabolic suppression and increased stress tolerance. The current study explores physiological adaptations related to diapause in three beetle species at high latitudes in Europe. From an ecological perspective, the comparison is interesting since one species (Leptinotarsa decemlineata) is an invasive pest that has recently expanded its range into northern Europe, where a retardation in range expa…

Schools without measurements : towards a pedagogy of recognition

2017

Since the OECD launched the Program for International Student Assessment (PISA) in 2000, education measurements have mainly been concerned with recording and issuing results in terms of school success or failure based on items aimed at measuring academic achievement. A major consequence of this obsession with quantifiable results, which stems from a sort of statistical monoculture, has been a shift of our attention away from the seminal fact that, indeed, educational disparities are directly linked to social inequalities. Besides, the application of accountability criteria within systems of education tends to hide the increasing deregulation of the former. Contrary to its seeming appearance…

Un biais d'estimation de la rentabilité de l'éducation dans le modèle de gains de Mincer appliqué à des données transversales

Travail posté et maladies cérébro- et cardiovasculaires : revue critique et synthèse des preuves épidémiologiques

2013

National audience; Une revue critique de la littérature a été menée sur le lien entre travail posté (TP) et survenue de maladies cérébro- et cardiovasculaires (MCCV). Dans plusieurs études de bonne qualité, le TP est associé à une augmentation modeste mais significative du risque de maladies cardiaques ischémiques fatales et non fatales. Les conclusions sont moins claires pour le lien avec la mortalité cardiovasculaire ischémique et les pathologies cérébrovasculaires. Sur le plan de la causalité, des biais de sélection difficiles à prendre en compte sur le plan méthodologique ne peuvent être écartés pour expliquer ces associations observées. Lien causal ou marqueur socio-économique ? Cette …

Different trophic positions among social vespid species revealed by stable isotopes

2021

The social vespid wasps are common insect predators and several species behave in unison in the same biotopes. It is commonly accepted that social wasps are mainly opportunistic generalist predators without differences in prey selection and hence they compete for the same food resources. Trophic positions of six vespid wasp species and their potential prey from four sites in Finland and one in the UK were evaluated using carbon and nitrogen stable isotopes (δ13C and δ15N). The difference in isotope values indicated different trophic positions among species. In general, Dolichovespula spp. showed higher δ15N values than Vespula spp., which suggests that Dolichovespula forage on higher trophi…

Titmice are a better indicator of bird density in Northern European than in Western European forests

2022

Publisher Copyright: © 2022 The Authors. Ecology and Evolution published by John Wiley & Sons Ltd. Population sizes of many birds are declining alarmingly and methods for estimating fluctuations in species’ abundances at a large spatial scale are needed. The possibility to derive indicators from the tendency of specific species to co-occur with others has been overlooked. Here, we tested whether the abundance of resident titmice can act as a general ecological indicator of forest bird density in European forests. Titmice species are easily identifiable and have a wide distribution, which makes them potentially useful ecological indicators. Migratory birds often use information on the densit…

Spillovers from the oil sector to the housing market cycle

2017

We assess the spillovers from the oil sector to the housing market cycle using quarterly data for 20 net oil-exporting and -importing industrial countries, and employing continuous- and discrete-time duration models. We do not uncover a statistically significant difference in the average duration of booms and normal times in the housing markets of those net oil-importers and net oil-exporters. Similarly, the degree of exposure to commodity price fluctuations does not seem to significantly affect the housing market cycle. However, we find that housing booms are shorter when oil prices increase than housing busts when oil prices decrease. We also show that the net oil-importers are more vulne…

Estimation de la relation de salaires de Mincer : choix de specification et enjeux économétriques

2012

In the present doctoral thesis, we estimated Mincer’s (1974) semi logarithmic wage function for the French and Pakistani labour force data. This model is considered as a standard tool in order to estimate the relationship between earnings/wages and different contributory factors. Despite of its vide and extensive use, simple estimation of the Mincerian model is biased because of different econometric problems. The main sources of bias noted in the literature are endogeneity of schooling, measurement error, and sample selectivity. We have tackled the endogeneity and measurement error biases via instrumental variables two stage least squares approach for which we have proposed two new instrum…
