Effective social education of exclusion: contributions from social pedagogy

The objective of this research was to identify effective strategies for socio-educational intervention with adolescents aged 12–16 years in a situation of social risk and provide some proposals from the field of social pedagogy. The research was conducted in three autonomous regions of Spain—Madrid, Galicia and Catalonia—between 2011 and 2013 and used the grounded theory approach. Thirty one practitioners and 19 adolescents participated in the focus groups and interviews. The main results suggest central strategies related to the empowerment and participation of adolescents, resilience and the flexible planning of interventions, with relevant implications for practice and policies.     

The Loss of Efficiency Estimating Linear Functions under Restrictions

This article is motivated by the problem of estimating contrast in a one-way ANOVA model with restrictions in the parameter vector. We prove that when the restrictions are given by a tree order or a simple order the MLE of some contrast has greater MSE than the unrestricted estimator. A similar behaviour of the MLE is exhibited in a general restricted setting given by a multivariate normal distribution with mean vector constrained to belong to a circular cone. The approach we use focuses on the central direction of the cones. These directions appear to have the greater MSE when the dimension of the restricted cone is big enough.     

Association of low serum 25-hydroxyvitamin D levels with the frailty syndrome in Mexican community-dwelling elderly

Objective: Since vitamin D is an important regulator of muscle function, the effect of vitamin D deficiency on frailty syndrome has been recently studied. This cross-sectional study aimed to determine the association between 25(OH)-vitamin D levels and frailty status in Mexican community-dwelling elderly.

Methods: Sample of 331 community-dwelling elderly aged 70 or older, a subset of those included in the “Coyoacán cohort” were included. 25(OH)-vitamin D assay and frailty status were measured.

Results: Mean age was 79.3 years and 54.1% were women. Those classified as frail were more likely to have lower Mini-Mental State Examination score (p?=?0.015), more disability for instrumental activities of daily living (p?p?p?Conclusion: These results suggest that older adults with low 25(OH)-vitamin D levels are associated with the probability to being frail compared with those with sufficient vitamin D levels.     

The Persistence of the slave market in seventeenth-century Central Mexico

This study, based on an extensive notarial database, demonstrates the significance of slavery in Central Mexico during the seventeenth century. Thousands of bills of sale from Mexico City and Puebla – the largest and most lucrative slave markets in the region – show that the slave trade did not collapse with the end of the Portuguese asiento in 1640. A growing population of American-born creoles sustained the market during the subsequent decades, along with a modest number of new African arrivals. In 1700, slavery remained integral to Central Mexico's economy.     

Cognition and Behavior in Normal‐Form Games: An Experimental Study

This paper reports experiments designed to study strategic sophistication, the extent to which behavior in games reflects attempts to predict others’ decisions, taking their incentives into account. We study subjects’ initial responses to normal‐form games with various patterns of iterated dominance and unique pure‐strategy equilibria without dominance, using a computer interface that allowed them to search for hidden payoff information, while recording their searches. Monitoring subjects’ information searches along with their decisions allows us to better understand how their decisions are determined, and subjects’ deviations from the search patterns suggested by equilibrium analysis help to predict their deviations from equilibrium decisions.     

A Simple Model of Severance Pay Determination: The Case of Individual Dismissals in Spain

In this article we model the determinants of severance pay for individual dismissals in Spain, following an idea proposed by Jimeno and Toharia (Economistas 55: 243–255, 1993). We point out the importance of severance pay settled before judgment, since the legal framework creates a bargaining space to determine the amount paid by firms in cases of individual dismissal. The model is a simple pre‐trial bargaining game between the firm and the worker. It predicts a higher settled severance pay for dismissals on economic grounds than on disciplinary ones, which could explain the perceptions held about the wide use of disciplinary dismissals in Spain. In addition, this approach could be useful in designing labour market reforms aimed at changing dismissal costs, because it allows us to determine the key variables affecting settled severance pay. Our simple model predicts that the key variables for Spain are the severance pay for unfair dismissal and the probability of unfair dismissal.     

Reliability, Validity, and Classification Accuracy of a Spanish Translation of a Measure of DSM-IV Diagnostic Criteria for Pathological Gambling

The aim of this study was to measure the reliability, validity, and classification accuracy of a Spanish translation of a measure of DSM-IV diagnostic criteria for Pathological Gambling (PG). Participants were 263 male and 23 female patients seeking treatment for PG and a matched non-psychiatric control sample of 259 men and 24 women. A Spanish translation of a 19-item measure of DSM-IV diagnostic criteria for PG (Stinchfield 2003) was administered along with other validity measures. The DSM-IV diagnostic criteria were found to be internally consistent with a coefficient alpha of .95 in the combined sample. Evidence of satisfactory convergent validity included moderate to high correlations with other measures of problem gambling. Using the standard DSM-IV cut-score of five, the ten criteria were found to yield satisfactory classification accuracy results with a high hit rate (.95), high sensitivity (.92), high specificity (.99), low false positive (.01), and low false negative rate (.08). Lowering the cut score to four resulted in modest improvements in classification accuracy and reduced the false negative rate from .08 to .05. The Spanish translation of a measure of DSM-IV diagnostic criteria for PG demonstrated satisfactory psychometric properties and a cut score of four improved diagnostic precision.     

Publication Trends in The Analysis of Verbal Behavior: 1999–2008

The Analysis of Verbal Behavior (TAVB) publishes experimental and theoretical papers relevant to a behavioral analysis of language. Normand, Fossa, and Poling (2000) reviewed the published studies in TAVB across several dimensions and found that despite the growth of the journal, most articles published in TAVB from 1982 to 1998 were nonexperimental. The current study extends this review by analyzing articles published in TAVB from 1999 through 2008. Results showed that 48% of the articles published between 1999 and 2008 were experimental (65% in the last 4 years), 93% of them used within-subject experimental designs, and most of them (54%) included children with developmental disabilities. This suggests an increased interest in the experimental analysis of verbal behavior with a focus on teaching language to individuals with disabilities.     

Sociodemographic Profiles and the Causes of Regular Venezuelan Emigration

The following study examines the characteristics of the Venezuelan emigrant population which crossed the border between Táchira state (Venezuela) and La Parada, Villa del Rosario Municipality, North Santander (Colombia) between April 9th and May 6th of 2018. The data were collected through a structured survey with 14,578 respondents. Using multiple correspondence factor analysis and positioning maps, we identified three different emigrant profiles that have a single fundamental cause of emigration: the current economic situation. These three groups differ in age, education level, and marital status. Profile 3 stands out as it is formed by single, young professionals who feel uncertainty because they do not think they can have a prosperous future in Venezuela. We conclude with an acknowledgement of the current humanitarian crisis (around both food and health) in Venezuela and the need to generate inclusive migratory policies in host countries.
