Executive Functions in School‐age Children: Influence of Age,Gender, School Type and Parental Education

Summary: This study aimed to evaluate whether age, gender, type of school and parental education could predict executive performance in school‐age children. Unconstrained, phonemic and semantic verbal fluency tasks (n = 402), as well as the Hayling Sentence Completion Test (n = 275) and the Random Number Generation task (n = 274) were administered to typically developing 6‐to‐12‐year‐old children. A hierarchical regression analysis was performed (p ≤ 0.05). The most significant explanatory models involved child age and parental education, as well as these two variables in addition to the type of school attended by the child. The main individual predictors of executive performance were age and school type. These results may be related to structural and functional alterations in the brain, an increased repertoire of cognitive strategies, the effects of education and the intensity of environmental cognitive stimulation. These findings may contribute to the development of stimulation and intervention programs for EF in clinical and educational settings.Copyright © 2017 John Wiley & Sons, Ltd.     

Computerized procedure for analyzing hand kinematics with a peg-moving task (Sarah-Pegworks)

This article describes Sarah-Pegworks, a computerized procedure for analyzing hand kinematics based on the peg-moving task. The procedure, developed in Visual Basic 6 programming language, includes (1) processing raw data from an infrared motion-tracking system, (2) identifying movement components, and (3) analyzing and presenting hand kinematic information in numerical and graphic outputs. Fifty-five normal adults set the parameters relative to filtering and movement identification. A case was presented to illustrate the clinical value of this procedure.     

Theta synchronizes the activity of medial prefrontal neurons during learning

Memory consolidation is thought to involve the gradual transfer of transient hippocampal-dependent traces to distributed neocortical sites via the rhinal cortices. Recently, medial prefrontal (mPFC) neurons were shown to facilitate this process when their activity becomes synchronized. However, the mechanisms underlying this enhanced synchrony remain unclear. Because the hippocampus projects to the mPFC, we tested whether theta oscillations contribute to synchronize mPFC neurons during learning. Thus, we obtained field (LFP) and unit recordings from multiple mPFC sites during the acquisition of a trace-conditioning task, where a visual conditioned stimulus (CS) predicted reward delivery. In quiet waking, the activity of mPFC neurons was modulated by theta oscillations. During conditioning, CS presentation caused an increase in mPFC theta power that augmented as the CS gained predictive value for reward delivery. This increased theta power coincided with a transient theta phase locking at distributed mPFC sites, an effect that was also manifest in the timing of mPFC unit activity. Overall, these results show that theta oscillations contribute to synchronize neuronal activity at distributed mPFC sites, suggesting that the hippocampus, by generating a stronger theta source during learning, can synchronize mPFC activity, in turn facilitating rhinal transfer of its activity to the neocortex.     

Brazilian version of the Protocole Montréal d'Evaluation de la Communication (Protocole MEC): normative and reliability data

The lack of standardized instruments to evaluate communication disorders related to the right hemisphere was verified. A new evaluation tool was developed: Protocole Montréal d'Evaluation de la Communication--Protocole MEC, adapted to Brazilian Portuguese--Bateria Montreal de Avalia??o da Comunica??o--Bateria MAC (Montreal Evaluation of Communication Battery). The purpose was to present stratified normative data by age and educational level, and to verify the reliability parameters of the MEC Battery. 300 individuals, between the ages of 19 and 75 years, and levels of formal education between 2 and 35 years, participated in this study. They were divided equally into six normative groups, according to three age categories (young adults, intermediary age, and seniors) and two educational levels (low and high). Two procedures were used to check reliability: Cronbach alpha and reliability between evaluators, Results were established at the 10th percentile, and an alert point per task for each normative group. Cronbach's alpha was, in general, between .70 and .90 and the average rate of agreement between evaluators varied from .62 to .94. Standards of age and education were established. The reliability of this instrument was verified. The psychometric legitimization of the MEC Battery will contribute to the diagnostic process for communicative disorders.     

Friendship Values and Cross-Category Friendships: Understanding Adult Friendship Patterns Across Gender, Sexual Orientation and Race

The present research used an intersectional analysis in examining whether women and men who have, versus do not have, cross-category friendships differ in what they value as important in a close friendship. Parallel analyses were conducted to examine cross-orientation and cross-race friendships across gender and identity status (minority and majority), with age as a covariate for all analyses. Participants were 1415 adult women and men, ranging in age from 18-80, residing in the United States, who completed a friendship profile questionnaire by reporting basic demographic information about themselves and their close friends. Participants’ importance ratings of six different friendship values were utilized to interrogate existing friendship patterns. Three general friendship values (trust and honesty, respect friend as person, there when needed) and three cross-identity salient friendship values (similar lives & experiences, similar values, nonjudgmental) were considered. Individuals with and without cross-category friendships did not significantly differ in their ratings for any of the three general friendship values. Individuals with cross-orientation and cross-race friendships placed less importance on similar lives & experiences than those with no such friendships. Other cross-identity salient friendship values were uniquely related to cross-orientation and cross-race friendship patterns. Although women rated all six friendship values as more important than did men, women and men displayed similar friendship value patterns across cross-category friendships and identity. These findings are discussed in the context of feminist intersectional theory.     

Satisfaction of Health Science teachers with the convergence process of the European Higher Education Area

The European Higher Education Area (EHEA) has implied a major transformation of university studies in European countries. The aim of this study was to assess the satisfaction of university teachers in the area of Health Sciences with the convergence process to determine positive and negative aspects in their practices. The sample was composed of 1,361 teachers of Spanish public universities. They all participated in an ad hoc survey that included questions pertaining to the following issues: a) personal and professional information, b) general and institutional aspects, c) aspects related to teaching, research, and administrative work, d) methodology and the teaching-learning process, e) assessment of students, f) training of teachers, and g) coordination, organization, and resources at the school. Results reveal that teachers are not totally satisfied with the way the EHEA is being established. In conclusion, certain changes would be necessary to achieve real convergence between countries.

Con este fin, en primer lugar se analizarán los principales hallazgos de las investigaciones que relacionan la familia, la escuela y el grupo de iguales con la aparición de drogodependencias en los adolescentes. Como segundo paso se apuntarán las líneas generales de aplicación de estos hallazgos en programas de prevención e intervención.     

Mutual Funds Efficiency Measurement under Financial and Social Responsibility Criteria

Socially responsible investors pursue financial as well as nonfinancial goals. Whereas the role of financial criteria in investment decisions is well understood, much less is known on the influence of social responsibility considerations. This work seeks to integrate both dimensions within a data envelopment analysis framework consistent with second‐order stochastic dominance efficiency. We compare the performance of conventional versus socially responsible mutual funds on an empirical data set. Our data do not support the conjecture that conventional mutual funds exhibit superior overall performance. Copyright © 2013 John Wiley & Sons, Ltd.
