Trends in Inequality of Opportunity for Developing Countries: Does the Economic Indicator Matter?

Social Indicators Research - The aim of this paper is to shed some light on the behaviour of Inequality of Opportunity (IOp henceforth) in developing countries. The analysis is carried out using...     

Interrupted aspirations: research and policy on Gitano education in a time of recession,in Spain

During the past decade, Gitano students’ school success and its cultural, social and emotional consequences have been largely unexplored, particularly in a new context: the deep economic crisis in Spain. This study reviews and analyses the evolution of the research production and the changing contexts of policy trends affecting the ‘Roma education issue’ as they have developed in Spain during the past decade (2004–2014). The authors take as a starting point the groundbreaking study published in 2004 that focused on trajectories of educational achievement and continuity among Gitano youth, and go on to reconstruct the approaches undertaken by qualitative, quantitative and evaluation research since then, in relation to their contributions to improve policy recommendations. The role played by Spanish and European social and educational strategies addressed to the Gitano/Roma population is critically explored to challenge the controversial notion of a ‘Spanish model of Roma integration’. Finally, the authors argue that the deterioration of public education and the virtual disappearance of social benefits in recent years, in addition to the worrying actions taken against Roma citizens in the EU, are to account for the interrupted aspirations of a whole generation of Gitano/Roma youth.     

Optimum design-based ratio estimators of the distribution function

The ratio method is commonly used to the estimation of means and totals. This method was extended to the problem of estimating the distribution function. An alternative ratio estimator of the distribution function is defined. A result that compares the variances of the aforementioned ratio estimators is used to define optimum design-based ratio estimators of the distribution function. Different empirical results indicate that the optimum ratio estimators can be more efficient than alternative ratio estimators. In addition, we show by simulations that alternative ratio estimators can have large biases, whereas biases of the optimum ratio estimators are negligible in this situation.     

Spatial Analysis of the Relationship Between a Life Quality Index,HDI and Poverty in the Province of Buenos Aires and the Autonomous City of Buenos Aires,Argentina

The study of Quality of Life, Poverty and Human Development shares several elements. Nonetheless, while poverty is a measure of “lack” based on a set of basic need variables (unsatisfied basic needs—UBN), human development index (HDI) is derived from the notion of human capabilities. Quality of Life, however, is a measure of achievement. Our goal is to analyze the degree of spatial correspondence between a life quality index (LQI) and the other indices by using bivariate spatial autocorrelation with its global and local values. The comparison of these three indicators at a municipal level in the province of Buenos Aires and in the Autonomous City of Buenos Aires (the Federal Capital of Argentina) reveals a medium spatial correspondence which leaves room for discussion about the scope and limitations of the indicators. HDI and UBN have a similar spatial configuration while the LQI yields a more fragmented distribution associated to the complexity of its variables, dimension and weights.     

La flexibilité, une arme contre le chômage? Analyse empirique du marché du travail espagnol

L'Espagne a connu en 2010 et 2012 deux réformes majeures du marché du travail. Celles-ci reposaient sur l'idée qu'il suffisait d'accroître la flexibilité du travail et de décentraliser la négociation collective pour faire baisser le chômage (thèse de la flexibilité). Les auteurs estiment pour leur part que le comportement du chômage dépend largement de la demande et de la structure sectorielle de l'économie (thèse structurelle). Ils évaluent l'apport de ces deux hypothèses dans une analyse reposant sur des données de panel de niveau infranational. Leurs résultats tendent à infirmer la thèse de la flexibilité et font ressortir le rôle primordial des facteurs cycliques et structurels.     

Postural analysis of eight university student wheelchair users when performing written exercises in their classroom: a case study in Santiago de Cali, Colombia

In students with physical disabilities, the more energy and time required and invested into finding a good posture, the longer the learning process takes. For this reason, the objective of this study was to characterize the posture in the act of writing of wheelchair users in a classroom. Eight students, (three women) aged 18-40, of some of the main universities of the city of Santiago de Cali participated. An observational field study filming of approximately 10 minutes was done while they took notes in their classes. Posture of the head, trunk, and upper extremities was analyzed with respect to its axis and the type of movement in each joint. The postures were classified depending on the location of support surface finding five different postures in the eight students. In these five postures some biomechanical risk factors, usually present in wheelchair users, are increased when they are associated with those postures. Those associated risk factors are: possible disc spine deformation, muscular stress and causing of pressure ulcer. In conclusion, in four of these five postures a poor interaction among person, task and work desk was observed. Therefore, seven of the eight students in this study were found to have a posture that could be considered risky.     

ZONING UNDER SPATIAL PRICE DISCRIMINATION

This paper investigates zoning in a duopoly model of spatial price discrimination. We find that the zone in which the firms are not allowed to locate depends on the bias of the regulator. A bias toward firms is deduced when locations around the central area are forbidden, and a bias toward consumers exists when firms are only allowed to locate at places around the central area. The design of the zoned area guarantees that firms locate optimally and works under simultaneous or sequential choice of locations by the two firms. (JEL L13, R38)     

Television news consumption and public attitudes towards immigration: a multi-level approach / Consumo de información televisiva y actitudes publicas hacia la inmigración: un enfoque multinivel

This paper analyses the association between TV news consumption and public attitudes towards immigration. A multi-level model is used to study the complex relationship between TV news consumption, how the media treat immigration and public attitudes towards minority groups based on a survey of university students. Multi-level analysis results show the impact of aggregate consumption of TV news on the perception of the current immigration phenomenon and the cognitive/affective components of attitude. It also demonstrates the usefulness of this analytical approach for understanding the processes that describe the relationship between the media and attitudes towards immigration.     

Remittances and labour market outcomes: Evidence from Mexico

The effects of remittances on labour market outcomes have been studied by many researchers, primarily using micro‐level data. While a few studies have also used macro‐level data, they suffer from endogeneity bias due to the inclusion of remittances in their estimations. The present study attempts to fill the gap in the literature by using a set of panel data of Mexican states and by addressing the endogeneity bias with a system GMM (generalized method of moments) estimator. The main conclusions are that remittances increase labour force participation rates and reduce median hours worked, critical employment and unemployment duration.     

Nonparametric estimation of transition probabilities in a non-Markov illness–death model

In this paper we consider nonparametric estimation of transition probabilities for multi-state models. Specifically, we focus on the illness-death or disability model. The main novelty of the proposed estimators is that they do not rely on the Markov assumption, typically assumed to hold in a multi-state model. We investigate the asymptotic properties of the introduced estimators, such as their consistency and their convergence to a normal law. Simulations demonstrate that the new estimators may outperform Aalen–Johansen estimators (the classical nonparametric tool for estimating the transition probabilities) in non-Markov situation. An illustration through real data analysis is included.
