Interactive effects of personality and separation as acculturation style on adolescent antisocial behaviour

The primary aim of this study was to assess the interaction between personality and acculturation variables in predicting antisocial behaviour among adolescent immigrants living in Spain. Previous studies have shown that the acculturation style referred to as separation (rejection of the host country's culture, and a strong desire to preserve the culture of the country of origin) was strongly related to antisocial behaviour among immigrants. A further aim of this study was to examine if the relationship between separation and antisocial behaviour was moderated by personality variables, in particular impulsivity, sensation-seeking, and personal competence. Self-reported data of a sample of 750 adolescent immigrants living in Galicia's and Madrid's regions (Spain) were gathered using previously validated scales. The results revealed that both separation and personality variables were significantly related to antisocial behaviour. Moreover, hierarchical regression analysis with the interaction terms entered found significant moderating effects i.e., the relationship between separation and antisocial behaviour was significantly amplified when impulsivity or sensation-seeking were high. The results underscore the need to examine the effects of personality, acculturation, and the interaction between both on antisocial behaviour among adolescent immigrants.     

Estructuras textuales y procesos de comprensión: un programa para instruir en la comprensión de textos

Resumen

El trabajo tiene la siguiente línea argumental: 1) Existe una relación entre las estructuras de los textos y los procesos de comprensión. 2) Los lectores con menor capacidad no se aprovechan de esas propiedades presentes en los textos y, como consecuencia, su representación del significado carece de orden y coherencia. 3) Si se instruye a los sujetos con una pobre capacidad de comprensión a detectar y usar las propiedades de los textos, puede reducirse la distancia que les separa de los sujetos con una buena capacidad de comprensión. Consecuentemente, el programa de instrucción está centrado en las actividades cognitivas que permiten seguir la progresión temática de los textos, extraer el significado global (aplicación de las macrorreglas de selección, generalización e integración) y a reconocer y usar las formas organizativas básicas. Para poner a prueba el programa de instrucción se contrastan los efectos de este programa con otro de carácter más tradicional y otra condición de control aplicando estas tres condiciones a sujetos de dos niveles de competencia, lo que da lugar a un diseño antes/después con dos niveles de competencia por tres tratamientos.     

Temperature dependence of the flow stress in Ir3Nb with the L12 structure

The effective s-d spin interaction is derived exactly for the one-impurity Anderson model via a unitary transformation. The unitary transformation has been calculated up to infinite order, thus an exact transformation was performed in the strict mathematical sense.

The influence of breast cancer survivors' Perceived partner social support and need satisfaction on depressive symptoms: A longitudinal analysis

The present study examines the ways in which breast cancer survivors’ perceptions of emotional and instrumental social support from an intimate partner and need satisfaction in their partner role influence depression during and after breast cancer treatment. Our sample was comprised of 163 women who were an average of 57 years old, mostly White/Caucasian, and diagnosed primarily with early-stage breast cancer. Longitudinal data were analysed using both multilevel and structural equation modelling. Results reveal that (a) greater perceived partner emotional support is associated with lowered levels of depression at each wave, (b) partner-role need satisfaction mediates the relationship between perceived partner emotional support and depression at each wave, (c) perceived partner emotional support predicts subsequent changes in depression by way of need satisfaction and (d) depression prospectively predicts lowered perceptions of partner emotional and instrumental support. The findings confirm that basic need satisfaction, within intimate relationships, is an important predictor of lowered depression among breast cancer survivors.     

The Social Construction of Human Kinds

Social construction theorists face a certain challenge to the effect that they confuse the epistemic and the metaphysical: surely our conceptions of something are influenced by social practices, but that doesn't show that the nature of the thing in question is so influenced. In this paper I take up this challenge and offer a general framework to support the claim that a human kind is socially constructed, when this is understood as a metaphysical claim and as a part of a social constructionist debunking project. I give reasons for thinking that a conferralist framework is better equipped to capture the social constructionist intuition than rival accounts of social properties, such as a constitution account and a response‐dependence account, and that this framework helps to diagnose what is at stake in the debate between the social constructionists and their opponents. The conferralist framework offered here should be welcomed by social constructionists looking for firm foundations for their claims, and for anyone else interested in the debate over the social construction of human kinds.     

Authentic leadership and its relationships with work engagement and organizational citizenship behaviors in military units: The role of identification as a mediating variable

The objective of the study is to explore the relationship of authentic leadership with work engagement and organizational citizenship behaviors (OCB) in military units, measuring the mediating effect of personal identification with the leader and social identification with the military unit. We used the Structural Equation Modeling (SEM) technique to analyze data from a sample of 225 Spanish military troops. The results showed that social identification with the military unit influenced the relationship of authentic leadership with the outcome variables.     

Improvement in working memory is not related to increased intelligence scores

The acknowledged high relationship between working memory and intelligence suggests common underlying cognitive mechanisms and, perhaps, shared biological substrates. If this is the case, improvement in working memory by repeated exposure to challenging span tasks might be reflected in increased intelligence scores. Here we report a study in which 288 university undergraduates completed the odd numbered items of four intelligence tests on time 1 and the even numbered items of the same tests one month later (time 2). In between, 173 participants completed three sessions, separated by exactly one week, comprising verbal, numerical, and spatial short-term memory (STM) and working memory (WMC) tasks imposing high processing demands (STM–WMC group). 115 participants also completed three sessions, separated by exactly one week, but comprising verbal, numerical, and spatial simple speed tasks (processing speed, PS, and attention, ATT) with very low processing demands (PS-ATT group). The main finding reveals increased scores from the pre-test to the post-test intelligence session (more than half a standard deviation on average). However, there was no differential improvement on intelligence between the STM-WMC and PS-ATT groups.     

Predictors of healthcare resource use in fibromyalgia

This work identifies which psychosocial, clinical and perceived health status factors predict health-resource use in Fibromyalgia (FM), considering the patients' assistance level. Participants were 315 FM patients from Primary Care (PC: n=101) and Rheumatology Services (RS: n=214). Stepwise regression analysis showed that self-efficacy variables were significant predictors of medication intake in PC, and, along with Illness-focused coping, of the health service use. In RS, perceived health status was the best predictor of medication intake. In any case, Pain intensity significantly predicted the use of health resources. These data offer a new perspective for intervention in these patients, taking into account the level of assistance.     

Successful aging: criteria and predictors

In the Anglo-Saxon scientific literature, successful aging has been consolidated during the last four decades. Nevertheless, several terms have been used as synonymous: healthy, active, productive, optimal, positive aging. Although, all these terms have been described through a broad set of bio-psycho-social factors, usually, research in this field reduces successful aging to daily life functioning and physical health. Also, in spite of the fact that authors consider that determinants might be multi-domain, empirical research usually reduces them to life styles. Logically, the prevalence of this kind of ageing found empirically is not very consistent and research of its determinants or predictors refers to biomedical conditions. In this study, data from 458 participants (170 males and 288 females; mean age: 66.47, range: 55-75) from ELEA ("Longitudinal Study of Active Aging") were examined. The results show (depending on the simple or multidimensional definitions used) a very varied range of proportions of successfully aging older persons as well as a large number of multi-domain predictors of successful ageing, among which are intelligence, personality and motivational psychological characteristics.
