Education as a Positional Good: A Life Satisfaction Approach

In this paper we empirically investigate the direct effects of education on utility. Besides investment aspects of education, the focus is placed on its consumption component and on education positional concerns. We use data from the World Values Survey (WVS) and adopt a life satisfaction approach. First, we find that education shows a significant effect on life satisfaction independent of its effect on income, thus identifying a consumption component of education. Furthermore, given that the contribution of education to individual wellbeing might depend partly on relative position rather than absolute levels, we next study whether education can be considered as a positional good. To this end we analyse the relationship between education and life satisfaction for people in different income groups in which the reference levels of education may differ. Additionally, we control for occupational status since benefits from education could appear via occupational benefits. Our results indicate that the contribution of education to subjective wellbeing is stronger as less people attain a given level of education, thus suggesting that this contribution is partly due to positional concerns.     

The effect of variability and carryover on average bioequivalence assessment: a simulation study

The purpose of this study was to evaluate the effect of residual variability and carryover on average bioequivalence (ABE) studies performed under a 22 crossover design. ABE is usually assessed by means of the confidence interval inclusion principle. Here, the interval under consideration was the standard 'shortest' interval, which is the mainstream approach in practice. The evaluation was performed by means of a simulation study under different combinations of carryover and residual variability besides of formulation effect and sample size. The evaluation was made in terms of percentage of ABE declaration, coverage and interval precision. As is well known, high levels of variability distort the ABE procedures, particularly its type II error control (i.e. high variabilities make difficult to declare bioequivalence when it holds). The effect of carryover is modulated by variability and is especially disturbing for the type I error control. In the presence of carryover, the risk of erroneously declaring bioequivalence may become high, especially for low variabilities and large sample sizes. We end up with some hints concerning the controversy about pretesting for carryover before performing ABE analysis.     

Design issues for population growth models

We briefly review and discuss design issues for population growth and decline models. We then use a flexible growth and decline model as an illustrative example and apply optimal design theory to find optimal sampling times for estimating model parameters, specific parameters and interesting functions of the model parameters for the model with two real applications. Robustness properties of the optimal designs are investigated when nominal values or the model is mis-specified, and also under a different optimality criterion. To facilitate use of optimal design ideas in practice, we also introduce a website for generating a variety of optimal designs for popular models from different disciplines.     

Modeling wind energy flux by a Birnbaum–Saunders distribution with an unknown shift parameter

In this paper, we discuss a Birnbaum–Saunders distribution with an unknown shift parameter and apply it to wind energy modeling. We describe structural aspects of this distribution including properties, moments, mode and hazard and shape analyses. We also discuss estimation, goodness of fit and diagnostic methods for this distribution. A computational implementation in R language of the obtained results is provided. Finally, we apply such results to two unpublished real wind speed data from Chile, which allows us to show the characteristics of this statistical distribution and to model wind energy flux.     

Obstacles invisibles et représentation des femmes aux postes de décision en Espagne

Les auteurs présentent les résultats d'une étude sur les caractéristiques personnelles et les qualifications d'hommes et de femmes assumant des fonctions de direction dans des entreprises espagnoles, leur situation professionnelle et leur point de vue sur l'égalité des sexes. Par rapport à leurs homologues masculins, les Espagnoles occupant des postes à responsabilités sont plus jeunes mais aussi qualifiées, voire plus, et elles ont moins d'enfants. Cependant, elles sont toujours confrontées à des obstacles qui empěchent la pleine exploitation d'un capital humain précieux. Malgré les mesures adoptées, plus de neuf postes de décision sur dix sont toujours occupés par des hommes.     

Managerial dominance and audit committee independence in Spanish corporate governance

The purpose of this paper is to analyse whether the independence of audit committees is affected by the degree of control exerted by managers over the board of directors. Results from a sample of 75 listed Spanish companies show that the majority of firms that voluntarily adopted an audit committee between 1998 and 2001, made an effort to guarantee their independence from management. The degree of independence is shown to be determined by the proportion of inside directors on the board, the same person holding both the CEO and board chairperson positions, and the level of management ownership. These findings may have political implications because existing regulations do not limit the presence of inside directors on audit committees. The presence of inside directors may compromise effectiveness, turning audit committees into instruments of management to provide the appearance of monitoring.

Deepening and widening the gap: The impacts of the COVID-19 pandemic on gender and racial inequalities in Brazil

Shaped by inconsistent policy decisions, the COVID-19 pandemic in Brazil has made structural gender and racial inequalities more acute. Black and low-income women are overburdened with unpaid domestic work, increased domestic violence, and more vulnerable due to informal and exploitative working regimes. These structural aspects are intensifying, since the pandemic has broadened inequalities at the intersection of gender, race, labor market, and social class. We examine pre- and during pandemic inequalities on three dimensions: (a) unpaid domestic and care work, (b) women's labor market participation, and (c) domestic violence. We link the care diamond model and racial stratification forwarding a feminist perspective by examining how the interlocking of race and gender in Brazil renders different socioeconomic dynamics to the detriment of Black and low-income women. Based on this evidence, we stress that a more equal future requires a better social protection and policies targeting the articulation of gender, race, and class.     

Putting experts in their place: Achieving policy impact as an outsider-academic in civil service reforms in Slovakia

This paper studies two processes of civil service reform in Slovakia during the period of 2014–2015 in order to reflect on the involvement of an ‘outsider-academic’ and her strategies to achieve policy impact. The context of such involvement are multi-level processes permeated by political interests and poor on evidence, which favour strategic interests, bargaining and political pressure and contestation (the mode of ‘powering’) and a mode of legal-based ‘puzzling’ as opposed to a conceptual, intellectual search for solutions friendly towards outside academics—and achieving only incremental results. We theorise on the success of these strategies (including helping serendipity, throwing ideas to see what sticks, mobilising allies, anchoring a non-binding concept, and finding and developing long-term connections) and sketch analogies and differences between the position of an outsider-academic and a policy entrepreneur. We rely on auto-ethnographic data and documentation of the work of the committees involved and their outputs.     

Latent groups and latent traits of participation in bullying via factor mixture analysis: An exploratory study

In this study, we drew on a person-centred approach to explore forms of involvement and roles in bullying. More specifically, we applied Factor Mixture Analysis (FMA) to an in-depth measure of bullying roles, with a view to identifying latent dimensions of participation in bullying and latent groups characterised by differential behavioural patterns. Participants were 899 high school students (51% females) attending the 9th (49%) and 11th grades (51%). The data analysis revealed six latent behavioural dispositions. Four of these overlapped with behavioural patterns typical of previously identified forms of participation in bullying, while two factors shed new light on bullying behaviours. We also identified four latent groups, whose profiles were only partially aligned with the roles previously theorised in the literature.
