Factorial Validity of the Maslach Burnout Inventory-Human Services Survey (MBI-HSS) in a Sample of Spanish Social Workers

Burnout has been considered important to understanding the well-being of social workers and the quality of the services they render. Despite the ample international usage of the Maslach Burnout Inventory, its psychometric properties have come into question and alternative models of measuring the inventory have been suggested. The purpose of this study was to examine the psychometric properties and the applicability of a Spanish version of the Maslach Burnout Inventory-Human Services Survey (MBI-HSS) in an incidental sample of 947 social workers. Three alternative models of the MBI-HSS were tested for the purpose of identifying the most suitable model for measuring burnout in Spain. The confirmatory factor analysis supported the theory that the model of three correlated factors was superior to alternative models of one and two factors. The structure of three factors (emotional exhaustion, depersonalization, and personal accomplishment) and 19 items showed the best adjustment and a suitable internal consistency of the dimensions of the MBI-HSS. These findings demonstrate that the MBI-HSS has validity and reliability acceptable for measuring burnout in social workers, providing valuable information to the managers of social services in order to reduce burnout among social workers. The limitations of the study and recommendations for future investigation are emphasized.     

The topological approach to the aggregation of preferences

(1) A domain of preferences allows for topological aggregation for each number of people if and only if this domain of preferences is contractible. (2) The combination of continuity and the Pareto principle implies the existence of a unique manipulator. (3) Arrow’s theorem can be translated into the previous statement. All of these results are obtained via algebraic topology. This paper introduces some of the tools developed in topology and applies them upon the problem of preference aggregation. This paper is based upon a lecture given at the conference “Mathematical aspects of social choice”, CREM, Université de Caen and CNRS, November 8–10, 2004. I thank the organizers Maurice Salles and Vincent Merlin for their warm hospitality, and the participants for the stimulating discussion. I am indebted to Bart Capéau and Roeland Vervenne for helpful remarks. I thank the referee for combining speed and quality.     

Development and Validation of a Scale for the Measurement of Adolescents’ Developmental Assets in the Neighborhood

The aim of this study was to develop a valid and reliable instrument to assess features of a neighborhood that are relevant to the development and adjustment of adolescents. First, a scale was created from a literature review. Second, the content validity of this scale was validated through expert opinion. Finally, the scale was administered to a sample population for analysis of its psychometric properties. The sample consisted of 2,400 adolescents (1,068 boys and 1,332 girls) between ages 12 and 17 who were secondary students in public and private schools in Western Andalusia. The results demonstrate the adequacy of the psychometric properties of the constructed scale.     

On simulation and properties of the stable law

The stable distribution, in its many parametrizations, is central to many stochastic processes. Many random variables that occur in the study of Lévy processes are related to it. Good progress has been made recently for simulating various quantities related to the stable law. In this note, we survey exact random variate generators for these distributions. Many distributional identities are also reviewed.     

Are “daddy’s boys” just as rich as daddy? The transmission of values between generations

The influence of parents’ savings behaviour on that of their children has often been remarked. This paper attempts to explain this “poids d’Anchise” via a unique French dataset collected by DELTA and TNS-Sofres in 2002 (Pat€r survey), which contains both savings and subjective information for two or three generations of the same family. Parents’ and children’s risk and discounting preferences are significantly positively intergenerationally correlated. The correlation coefficients are around 0.25, so that the two preferences are nonetheless far from identical. In addition, the elasticity of children’s wealth with respect to that of their parents is around 0.22. This correlation is corrected for the influence of age on wealth, and concerns only co-existing generations, that is before the most significant intergenerational transfers have taken place. The analysis of the raw correlations with a series of explanatory variables reveals that over 40 % of this elasticity can be explained by the permanent incomes of the two generations. Each of education and preferences separately account for about 20 %, and previous intergenerational transfers for about 13 %. When permanent income is controlled for, the contribution of savings preferences is around 13 %. The transmission of preferences therefore plays a non-negligible role in the intergenerational transmission of wealth inequalities, but is far from being the most important factor.     

A New Approach to Volatility Modeling: The Factorial Hidden Markov Volatility Model

A new process—the factorial hidden Markov volatility (FHMV) model—is proposed to model financial returns or realized variances. Its dynamics are driven by a latent volatility process specified as a product of three components: a Markov chain controlling volatility persistence, an independent discrete process capable of generating jumps in the volatility, and a predictable (data-driven) process capturing the leverage effect. An economic interpretation is attached to each one of these components. Moreover, the Markov chain and jump components allow volatility to switch abruptly between thousands of states, and the transition matrix of the model is structured to generate a high degree of volatility persistence. An empirical study on six financial time series shows that the FHMV process compares favorably to state-of-the-art volatility models in terms of in-sample fit and out-of-sample forecasting performance over time horizons ranging from 1 to 100 days. Supplementary materials for this article are available online.

Ethnic penalties? The role of human capital and social origins in labour market outcomes of second-generation Moroccans and Turks in the Netherlands

In Western Europe, the children of Moroccan and Turkish migrants were found to be significantly disadvantaged in the labour market. This ethnic gap was found to persist after considering differences in schooling, which was argued to reflect ‘ethnic penalties’ driven by cultural, religious, or racial factors. This study uses data from the 1st Wave of the ‘Netherlands Longitudinal Life-Course Study’ (2009–2010) to revisit the analysis of ‘ethnic penalties’ for second-generation Moroccans and Turks. Unlike in previous research, empirical analyses not only consider differences in schooling, but also skills and social origins. Results show substantial ethnic inequalities in the labour market, with the exception of women from Moroccan origins. For men, these ethnic inequalities do not disappear when human capital factors are considered, but they do when accounting for the unprivileged social origins of ethnic minorities. For women, the disadvantage of second-generation Turks in achieving privileged occupations clearly disappears when human capital and social origins are considered. Yet, the chances of being unemployed among women of Turkish origins persist after controlling for education, skills, and social origins. Overall, this study has global academic and public policy implications to understand the socioeconomic integration of the Moroccan and Turkish second generation in Western Europe.     

Topological aggregation, the case of an infinite population

 The literature on infinite Chichilnisky rules considers two forms of anonymity: a weak and a strong. This note introduces a third form: bounded anonymity. It allows us to prove an infinite analogue of the “Chichilnisky– Heal-resolution” close to the original theorem: a compact parafinite CW-complex X admits a bounded anonymous infinite rule if and only if X is contractible. Furthermore, bounded anonymity is shown to be compatible with the finite and the [0, 1]-continuum version of anonymity and allows the construction of convex means in infinite populations. With X=[0, 1], the set of linear bounded anonymous rules coincides with the set of medial limits. Received: 30 October 1993/Accepted: 22 April 1996
