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 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.     

Types of responses in 4-5-year-old children in conservation, classification, and theory of mind tasks

This study analyzes the type of responses that children between 4 and 5 years of age give to different tasks: conservation, classification and tasks of the theory of mind (ToM). Types of responses were observed with the Observation of Cognitive and Meta-cognitive Skills Inventory, which identifies: attention, receptive and expressive language, planning processes, and meta-cognitive processes. Significant differences were found according to the variable age in: (a) the use of attentional strategies in performance of ToM tasks, (b) the use of receptive and expressive language in the performance of all tasks, (c) the use of planning processes in the performance of conservation tasks; and (d) the use of meta-cognitive processes to solve ToM tasks.     

Analysing the Influence of Autonomous and Controlling Social Factors Within the Theory of Planned Behaviour

The aim of this study was to analyse the effects of autonomous (i.e., autonomy support from parents and peers) and controlling (i.e., social physique anxiety) social factors on future intention to exercise, integrating the distal (i.e., basic psychological needs satisfaction and self‐determined motivation) and proximal (i.e., attitudes, perceived behavioural control and subjective norms) determinants of intention defined in self‐determination theory (SDT) and the theory of planned behaviour (TPB). Self‐report questionnaires were distributed to 390 secondary school pupils (male = 218, female = 172, M_age = 15.10, standard deviation = 1.94). The results of path analysis, controlling for past behaviour of physical activity, showed that social factors predicted future intention to exercise through the influence of the distal and proximal determinants. The main contribution of the study was to provide evidence that the proximal determinants of the TPB captured the direct influence of social factors, independent of the mediating effects of psychological needs satisfaction and self‐determined motivation towards exercise. Results supported the integration of the two theories, clarifying the processes of influence of autonomous and controlling social factors within the variables of SDT and the TPB.     

Psychoanalysis in Spain: A Brief Account of the Transformative Pathways Between the Psychoanalysts and Their Institutions

Psychoanalysis in Spain has a plural history. Rooted in the Freudian and Kleinian traditions, it has developed in different directions and incorporated trends from contemporary psychoanalysis. The impact of socio-political factors forced several migratory movements that came back to Spain under the form of criticism to classical psychoanalysis, following ideas that were emerging from Latin America (e.g., Pichon Rivière) and North America (Cultural and Interpersonal Psychoanalysis, Self Psychology, and Intersubjective System theories) that enriched psychoanalytic thinking, and promoted new psychoanalytic institutions. Finally, Steve Mitchell’s relational perspective plays a crucial role among present developments.
