Dual liver transplantation

Reperfusion is the key strategy in acute ST-segment elevation myocardial infarction(STEMI) care,and it is time-dependent.Shortening the time from symptom to reperfusion and choosing the optimal reperfusion strategy for STEMI patients are great challenges in practice.We need to improve upon the problems of low reperfusion rate,non-standardized treatment,and economic burden in STEMI care.This article briefly reviews the current status of reperfusion strategy in STEMI care,and also introduces what we will do to bridge the gap between the guidelines and implementation in the clinical setting through the upcoming China STEMI early reperfusion program.     

A model of relationship between collective identity and language in pluricultural and plurilingual settings: Influence on intercultural relations

The introduction of the Spanish Constitution in 1978, together with the development of the Statutes of Autonomy in the autonomous communities, established the co-official status of the regional language alongside Spanish. In one of these communities, Catalonia, located on the north-west boundary of the Lleida province, is the Aran Valley, where three languages coexist: Occitan-Aranese (regional language), Catalan (Catalonia's co-official language) and Spanish. The Valley of Aran is an ideal setting to study the construction of their collective identity and its relation to the language in an intercultural setting. As a result of immigration and the gradual decrease in the population born in the region, intercultural contact takes place among clearly distinct groups.In this work we present an analysis of the development of the Aranese identity and of the role language plays in this process and the way this process influences intergroup relationships. The study is based on a perspective that considers that the influence of language on the creation of collective identity is not a categorical and universal phenomenon [Fernández, M. A. (2000). Cuando los hablantes se niegan a elegir: monolingüismo e identidad múltiple en la modernidad reflexiva. Estudios de Sociolingüística 1 (1), 47–58; Siguán, M. (1996). L’Europa de les Llengües. Barcelona: Edicions 62]. Rather, we view language as a socially constructed means of expressing community membership. In this way, language plays an important part in the formation of Aranese identity, but the meaning given by the population to the language varies according to whether residents identify themselves or not with the Aranese world. At the same time, language also interferes in the relationship between the different groups living in the territory.     

Social comparison and cognitive performance: A descriptive approach in an academic context

Eighty pupils of different academic levels (i.e. strong vs weak) were asked to make estimations about the different subjects taught at school. Gathered post-experimentally, the data allow specification of the relation to intelligence in which each school subject stands for the two different types of subjects. Evaluations of the significations accorded to performances in the different disciplines were also obtained. In accordance with expectations, analysis of these estimations reveals that pupils in a failure situation have an “original” conception of the field of academic comparison. However, the data obtained show that this originality (i.e. this social differentiation) stays within the dominant value system which sets the confines of the field of academic comparison. Taken in conjunction with more experimental results reported elsewhere, these estimations suggest that the cognitive attitude adopted by subjects towards an object of knowledge (here academic) can, in certain conditions, be formed independently of the social significations associated with this object but not independently of the nature of the social insertion which subjects undergo at the time of this interaction.     

The social context of human learning: Some prospects for the study of socio-cognitive regulations

Numerous studies conducted by social, cognitive, and educational psychologists suggest that learning, cognitive functioning and development, and education are fundamentally embedded in a complex social matrix. Recent studies have demonstrated the influence on cognitive performances of several basic social variables, including evaluative pressure, group membership, situations of personal or categorical social comparison, and the academic value of the task. These findings clearly point out the necessity of considering the autobiographical dimension of the individual to explain this influence, an idea which is clearly consistent with other results obtained in studies on scholastic self-schemas. The present paper shows that the influence of the social context of cognition cannot be explained unless it is viewed from a sociocognitive perspective which considers the autobiographical memory of the individual.     

Effects of gender role and task content on performance in same-gender dyads: Transactive memory as a potential mediator

This experiment was designed to examine the effects of gender role and task content on performance in learning dyads and to test the potential mediator effect of an intragroup process related to transactive memory. A total of 44 same-gender dyads participated in the study and were asked to collaborate on a stereotypically masculine or feminine task in a laboratory setting. Collective performance and transactive memory were measured. As predicted, the results showed an interaction between group gender and task content on group performance, with male dyads showing poorer performance on a masculine task than female dyads. However, contrary to expectations, this moderation effect was not mediated by transactive memory, which appeared as a simple mediator of the relationship between group gender and performance. The results are discussed in the framework of the social role theory, and implications for future research in small learning groups are proposed.     

Hábitos lingüísticos en un contexto social diglósico: El caso del Baix Cinca

El problema de la enseñanza y dominio de una lengua alternativa se plantea con frecuencia con criterios estrictamente escolares o de competencia lingüística. Aquí se hace una aproximación claramente funcional, investigando los usos sociales reales de las lenguas en cuestión para cada uno de los ámbitos de la vida del niño en un intento de acercarse a las raíces del fenómeno de la diglosia.     

The influence of socioeconomic status,working memory and academic self-concept on academic achievement

European Journal of Psychology of Education - There is today ample evidence that academic achievement depends on individual disparities in socioeconomic status (SES), working memory (WM) and...
