Core Indicators to Assess Quality of Life in Population with Brain Injury

Assessing quality of life of people with brain injury has a relevant role for developing strategies focused on personal outcomes that allow us to guide good practices and rehabilitation. So far, assessment of quality of life for this population has been restricted to an evaluation of personal outcomes from a health-related quality of life perspective. This approach it is mostly centered on physical health, however, quality of life needs to be addressed from a holistic and multidimensional perspective. The goal of this study is to identify core indicators of quality of life in brain injury based on a comprehensive theoretical model focused on the most relevant aspects of this population functioning. A Delphi study was carried out to obtain the specific core indicators of quality of life for this population. The methodology used to reach a consensus about the best indicators and items to measure quality of life involved four rounds and 14 experts on rehabilitation of people with brain injury. The Delphi study provided evidence of content validity for the field-test version of a new scale that will be applied to a wide sample in order to empirically check its suitability for this population.     

Labor Mismatches: Effects on Wages and on Job Satisfaction in 17 OECD Countries

This study analyzes the effects of labor mismatches on wages and on job satisfaction in seventeen OECD countries by distinguishing between educational mismatch and skills mismatch. Using data from PIAAC, the results suggest that whereas educational mismatch shows greater effects on wages, the effects of labor mismatch on job satisfaction are generally better explained by skills mismatches. Both phenomena appear to be relevant for understanding the economic effects of labor mismatch and suggest that educational mismatch is not an accurate proxy for skills mismatch, mainly when the non-monetary effects of labor mismatch are addressed.     

Variations in horizontal and vertical individualism-collectivism in four regions of Mexico / Variaciones en el individualismo-colectivismo horizontal y vertical en cuatro regiones de México

Cultures can be analysed through cultural syndromes (shared patterns of beliefs, attitudes, norms, roles and values organized around a theme). One of these syndromes, individualism-collectivism, distinguishes collectivist cultures, which prioritize collective over individual interests, from individualist cultures, which value individual autonomy, achievement and freedom. These dimensions intersect with the horizontal-vertical syndrome, where verticality means the preference for a society organized by hierarchies, in contrast to a horizontal culture, which privileges equality. This paper explores these dimensions using a new instrument in a sample of 990 participants from four regions in Mexico. The results of exploratory and confirmatory factorial analyses show four theoretically congruent factors with adequate levels of internal consistency reaching metric equivalence criteria in three of the four samples. The scores show greater support for horizontal individualism and less support for vertical collectivism. These results are discussed within the context of a cultural shift towards individualism.     

Predicting attitudes and behavioural intentions towards social entrepreneurship: the role of servant leadership in young people / Predicción de las actitudes y las intenciones conductuales hacia el emprendimiento social: el papel del liderazgo de servicio en los jóvenes

: Social entrepreneurship (SE) refers to the development of innovative projects whose main aim is not individual profit but the transformation of society. The issue is particularly important for promoting youth development and participation. This research offers insights from two studies designed from a multi-dimensional perspective analysing attitudes and behavioural intentions towards social ventures built upon the constructs of servant leadership and lifestyles. Results of Study 1 indicated that servant leadership is a key predictor of attitudes and behavioural intentions towards social entrepreneurship, while having a violent lifestyle is negatively associated with these attitudes and intentions. Study 2 showed that servant leadership style predicted attitudes towards social entrepreneurship over and above other types of leadership (i.e., transformational, transactional and laissez-faire). These studies demonstrate the importance of considering servant leadership and relational styles as key factors in predicting attitudes and behavioural intentions regarding social and active participation of young people. Limitations of the study and applications to designing interventions aimed at improving attitudes and behavioural intentions towards social entrepreneurship are discussed.     

Satisfaction with the country and well-being: future expectations / Satisfacción con el país y bienestar: expectativas acerca del futuro

The role of expected personal well-being in the perception of the improvement (or deterioration) in living conditions and country satisfaction is analysed, as well as the relationship between the latter and life satisfaction and personal happiness. A national sample of N = 10,654 participants was used, collected through probabilistic, stratified, two-stage and cluster sampling. They responded to the Mexican Encuesta Nacional de Gastos de los Hogares (National Household Spending Survey, ENGASTO), which measures the spending on goods and services, aspects related to satisfaction with life and the country, and expectations of future personal well-being. Correlational analyses show positive associations between perceptions of the country and its expected development on the one hand and participants’ well-being on the other. Expectations of future personal well-being show indirect effects for both the relationship between the perception of improvement (or deterioration) of living conditions and country satisfaction, and the relation between the latter, happiness and life satisfaction.     

Persons with disabilities and the Colombian armed conflict

This article is about the armed conflict in Colombia and the situation for people with disabilities. Decades of internal conflict have created a complex situation which both gives rise to disability but also fails to take account of the many urgent needs of people with disabilities. Despite the ratification by Colombia of the UN Convention on the Rights of Persons with Disabilities, persons with disabilities are still not accorded a voice in the peace agreements. Although there is little known about the extent of disability in Colombia, it is important to understand the history of the Colombian armed conflict to see how it impacts on disability issues. We conclude by highlighting the legal instruments in Colombia which provide opportunities now to redress some of those wrongs.     

Robust estimators for additive models using backfitting

Additive models provide an attractive setup to estimate regression functions in a nonparametric context. They provide a flexible and interpretable model, where each regression function depends only on a single explanatory variable and can be estimated at an optimal univariate rate. Most estimation procedures for these models are highly sensitive to the presence of even a small proportion of outliers in the data. In this paper, we show that a relatively simple robust version of the backfitting algorithm (consisting of using robust local polynomial smoothers) corresponds to the solution of a well-defined optimisation problem. This formulation allows us to find mild conditions to show Fisher consistency and to study the convergence of the algorithm. Our numerical experiments show that the resulting estimators have good robustness and efficiency properties. We illustrate the use of these estimators on a real data set where the robust fit reveals the presence of influential outliers.     

Empirical phi-divergence test statistics for the difference of means of two populations

Empirical phi-divergence test statistics have demostrated to be a useful technique for the simple null hypothesis to improve the finite sample behavior of the classical likelihood ratio test statistic, as well as for model misspecification problems, in both cases for the one population problem. This paper introduces this methodology for two-sample problems. A simulation study illustrates situations in which the new test statistics become a competitive tool with respect to the classical z test and the likelihood ratio test statistic.     

Beyond convergence: unveiling variations of external franchise in Latin America and the Caribbean from 1950 to 2015

A growing literature deals with the models that states have developed to reach out to their emigrant communities. The literature covers a wide range of initiatives, most notably electoral policies. In this line of research, we present a comparative view of the citizenship policies of Latin American and Caribbean states using a data set that includes information (yearly observations from 1950 to 2015) of the external franchise policies of 22 countries. First, this paper describes the scope of inclusion of non-resident citizens in terms of electoral rights. Second, we study the evolution over time of the external franchise policies of the countries under study. Despite cultural, historical and obvious geographic commonalities across countries, the analyses reveal that the convergence trend in the external franchise policies developed by Latin American and Caribbean countries is limited to a most general level. Below that level many variations in terms of specific electoral rights, types and venues of representation of emigrants are observable. These variations range from exclusion of non-resident citizens in terms of electoral rights, to full inclusion, when emigrants have active and passive electoral rights in all the national elections held in the states of origin (presidential and/or legislative).
