An Empirical Analysis of the Determinants of Perceived Inequality
2017
Perception of inequality is important for the analysis of individuals' motivations and decisions and for policy assessment. Despite the broad range of analytic gains that it grants, our knowledge about measurement and determinants of perception of inequality is still limited, since it is intrinsically unobservable, multidimensional, and essentially contested. Using a novel econometric approach, we study how observable individual characteristics affect the joint distribution of a set of indicators of perceived inequality in specific domains. Using data from the International Social Survey Programme, we shed light on the associations among these indicators and how they are affected by covaria…
Teaching in times of COVID-19: determinants of teachers' educational technology use
2021
We conduct a large and nationwide survey among German teachers to investigate the determinants of teachers' adaption to an increased use of educational technology during the COVID-19 school closure...
How consistent are perceptions of inequality?
2020
Abstract Despite recent empirical evidence on the importance of perceived inequality, its analysis is still underexplored. In this paper we study whether unobserved perceptions of inequality are reflected in observed individual opinions in a consistent fashion. Inconsistency is relevant to ealuate the level of agreement that individuals share with respect to different domains of inequality. Using the wave from the 2009 International Social Survey Program in the US, we show that inequality is a complicated concept prone to inconsistencies and propose a testing procedure to an empirical appraisal. We find that inconsistencies exist though they may not extend to all the domains of inequality. …
Accumuler le capital humain tout au long de la vie: Quels facteurs prédictifs de la participation à la formation permanente?
2003
This article addresses the main predictors of adult education, using statistical methods different from those generally used by social science researchers. Its aim is twofold. First, it seeks to explain in a simple and comprehensible manner the methodological value of these methods (in relation to the use of structural models); secondly, it demonstrates the concrete usefulness of these methods on the basis of a recent piece of research on the data from the International Adult Literacy Survey (IALS).
Les sources de la qualité de l'éducation
2006
06033; L'objectif de ce papier est de tester l'existence d'une fonction de production éducative à partir de données issues des enquêtes internationales sur les acquis des élèves. Les résultats des estimations montrent des différences significatives quant aux relations entre inputs et outputs éducatifs selon le niveau économique des pays.
Les sources de la qualité de l'éducation : une nécessaire distinction du niveau économique des pays
2006
06036; L'objectif de ce travail est de tester l'existence d'une fonction de production éducative à partir de données issues des enquêtes internationales sur les acquis des élèves. Les résultats des estimations avec l'échantillon global d'une part, puis avec distinction selon le niveau économique des pays montrent des différences significatives quant aux relations entreinputs et outputs éducatifs. On constate qu'à mesure que le niveau économique des pays s'élève, l'impact des variables financières de l'éducation sur la performance aux tests diminue. Les relations diffèrent également avec la variable taille des classes. Ainsi, les incohérences trouvées dans les analyses antérieures en matière…
Questions d'alphabétisation dans le contexte africain
2012
Despite the proportion of illiterate people in sub-Saharan Africa having declined between 1985 and 2008, the number of illiterates has actually increased during the period. It is within this context, that since April 2000, the international community has been committed to six Education for All goals. One of these goals is to achieve a 50 per cent improvement in adult literacy levels by 2015. This thesis aims to analyse how primary education and literacy programs (two processes on which educational policy can intervene) enable the populations of sub-Saharan Africa to acquire basic reading skills. In the vast majority of African countries, the analysis based on household surveys shows that sc…
Bases de données internationales sur la qualité de l'éducation (1964/2005)
2006
06032; Dans ce travail de recherche, nous utilisons une méthode qui nous permet d'obtenir des indicateursqualitatifs du capital humain (IQCH), pour 105 pays, et pour chaque domaine de compétence(mathématiques, sciences, lecture) mesuré à travers l'ensemble des enquêtes internationalesd'acquis des élèves. Cette méthode repose sur la possibilité d'un re-calibrage des résultats d'uneenquête par rapport à une autre en ancrant les résultats sur les pays qui ont participé à au moinsdeux enquêtes différentes. Elle nous permet de construire des indicateurs de qualité du capitalhumain comparables pour plus grand nombre de pays comparé à ce qui est actuellement disponibledans la littérature. Nous obt…
Prediction of type 2 diabetes mellitus based on nutrition data
2021
Abstract Numerous predictive models for the risk of type 2 diabetes mellitus (T2DM) exist, but a minority of them has implemented nutrition data so far, even though the significant effect of nutrition on the pathogenesis, prevention and management of T2DM has been established. Thus, in the present study, we aimed to build a predictive model for the risk of T2DM that incorporates nutrition data and calculates its predictive performance. We analysed cross-sectional data from 1591 individuals from the population-based Cooperative Health Research in the Region of Augsburg (KORA) FF4 study (2013–14) and used a bootstrap enhanced elastic net penalised multivariate regression method in order to bu…
The Impact of Corporate Board Characteristics on Firm Value: A Literature Survey
2018
This chapter provides a review of theoretical and empirical studies that analyze the effects of board characteristics on firm performance. It serves the purpose of demonstrating different approaches to studying corporate board characteristics as well as the importance of examining these characteristics, namely, board size, board independence, board leadership, gender diversity, board busyness and staggered boards.
