Mothers' use of cognitive state verbs in picture-book reading and the development of children's understanding of mind: a longitudinal study   总被引：2，自引：0，他引：2  

Adrián JE  Clemente RA  Villanueva L 《Child development》2007,78(4):1052-1067

Mothers read stories to their children (N=41) aged between 3.3 years and 5.11 years old, and children then completed two false-belief tasks. One year later, mothers read a story to 37 of those children who were also given four tasks to assess their advanced understanding of mental states. Mothers' early use of cognitive verbs in picture-book reading correlated with their children's later understanding of mental states. Some pragmatic aspects of maternal input correlated with children's later outcomes. Two different factors in mothers' cognitive discourse were identified, suggesting a zone of proximal development in children's understanding of mental states.  相似文献   

High-throughput study of alpha-synuclein expression in yeast using microfluidics for control of local cellular microenvironment   总被引：1，自引：0，他引：1  

Rosa P  Tenreiro S  Chu V  Outeiro TF  Conde JP 《Biomicrofluidics》2012,6(1):14109-141099

Microfluidics is an emerging technology which allows the miniaturization, integration, and automation of fluid handling processes. Microfluidic systems offer low sample consumption, significantly reduced processing time, and the prospect of massive parallelization. A microfluidic platform was developed for the control of the soluble cellular microenvironment of Saccharomyces cerevisiae cells, which enabled high-throughput monitoring of the controlled expression of alpha-synuclein (aSyn), a protein involved in Parkinson's disease. Y-shaped structures were fabricated using particle desorption mass spectrometry-based soft-lithography techniques to generate biomolecular gradients along a microchannel. Cell traps integrated along the microchannel allowed the positioning and monitoring of cells in precise locations, where different, well-controlled chemical environments were established. S. cerevisiae cells genetically engineered to encode the fusion protein aSyn-GFP (green fluorescent protein) under the control of GAL1, a galactose inducible promoter, were loaded in the microfluidic structure. A galactose concentration gradient was established in the channel and a time-dependent aSyn-GFP expression was obtained as a function of the positioning of cells along the galactose gradient. Our results demonstrate the applicability of this microfluidic platform to the spatiotemporal control of cellular microenvironment and open a range of possibilities for the study of cellular processes based on single-cell analysis.  相似文献   

Acculturation, well-being and classroom behaviour among white British and British Asian primary-school children in the south–east of England: Validating a child-friendly measure of acculturation attitudes     

Dennis Nigbur  Rupert Brown  Lindsey Cameron  Rosa Hossain  Anick Landau  Dominique Le Touze  Adam Rutland  Charles Watters 《Int J Intercult Relat》2008,32(6):493-504

Using a sample of white British and British Asian primary-school children (N = 386, aged 5–11 years), we measured acculturation attitudes (own and perceived outgroup), correlated constructs (ingroup and outgroup affect and identification) and relevant outcomes (self-esteem, classroom demeanour) in a structured interview to validate a customised, child-friendly measure of acculturation attitudes based on Berry's framework. Scale items measuring desire for culture maintenance and intergroup contact loaded onto the predicted factors, were internally reliable and showed concurrent validity with affect and identification. The predictive utility of measures was demonstrated in associations between children's acculturation attitudes (or perceived discrepancies with those of the outgroup) and outcomes such as self-esteem and teacher ratings of emotional symptoms.  相似文献

On not being able to read or speak Malayalam: language and region in Kerala     

Fernando Rosa 《Inter-Asia Cultural Studies》2013,14(2):214-234

Abstract

This paper attempts to read aspects of language, history, and literariness historically from the perspective of both Brazil and Kerala. It is also an attempt to compare two very distinct places from within a framework centred on the South. Initially, region and nation are discussed, as well as modernity and development, and the issue of thinking South–South connections from an anthropological perspective. Next, the matter of the complex connected histories of Kerala within the Indian Ocean is mentioned, including Portuguese colonial history. The image and influence of Latin America in Kerala is briefly brought up, especially in what concerns literary influence. There follows an extended discussion of issues of literacy and the rise of the novel in Kerala as well as the historical intricacies of the construction of Malayalam as a modern medium. A contrast with the literary construction of modernity in Brazil is made, and the importance of English in Kerala is accordingly highlighted as well as the issue of the coloniality of the Portuguese within Brazil's complex creolized history. An analysis of the pioneering novel of Chandumenon is offered, and a comparison with a novel in Brazil is subsequently sketched. The different historical contexts of nineteenth century Brazil and Kerala are stressed. The close interrelatedness between issues of language, nation, and region is emphasised as well as the internal complexities of modernity in both regions.  相似文献   

Assessing Quality and Evaluating Performance in Higher Education: Worlds Apart or Complementary Views?     

Cláudia S. Sarrico  Maria J. Rosa  Pedro N. Teixeira  Margarida F. Cardoso 《Minerva》2010,48(1):35-54

This paper reflects on quality assessment and performance evaluation in higher education, namely by analysing the insufficient link between those two aspects. We start by reviewing the current state of the art regarding different processes and mechanisms of quality assessment and performance evaluation and discuss some of the major issues regarding the implementation of some of them. In particular, we analyse the current limitations regarding data collected, available and publicised on the performance of HEIs and the problems those limitations bring to a fair evaluation of higher education. Through this analysis we intend to contribute to a better understanding of the mechanisms of evaluation in higher education and the way these may lead to the promotion of better quality assessment practices and institutional management.  相似文献

Homework and academic achievement across Spanish Compulsory Education     

José Carlos Núñez  Natalia Suárez  Rebeca Cerezo  Julio González-Pienda  Pedro Rosário  Rosa Mourão 《教育心理学》2015,35(6):726-746

Homework (HW) is one of the most common school-related activities among parents, students and teachers. However, the need to assign HW to students has been extensively debated. The present investigation examines the relationship between specific HW variables (i.e. amount of HW completed, time spent on HW and perceived quality of HW time management) and academic achievement, while controlling for students’ gender and grade level. Participants included 454 students (ranging from 10 to 16?years of age) from three schools in northern Spain. A multivariate analyses of variance and path analyses showed that the amount of HW completed decreased with increased schooling, as did students’ perceived quality of HW time management. Data from hierarchical regression analyses completed by path analyses provided evidence that time spent on HW conjointly with perceived quality of HW time management explains how academic achievement is mediated by the amount of HW completed. These findings deepen the understanding of the complex impact of time spent on HW and on academic achievement.  相似文献   

Social presence and virtual collaborative learning processes in higher education / Presencia social y procesos de aprendizaje colaborativo virtual en educación superior     

Rosa Colomina  Ana Remesal 《Infancia y Aprendizaje》2015,38(3):647-680

The concept of social presence proposed in studies on communities of inquiry has highlighted both the importance and the challenges of integrating aspects such as affective and relational expressions among team members while solving collaborative learning tasks, in order to advance in a global comprehension of learning processes. This paper presents a theoretical and methodological proposal for tackling this issue from a socio-cultural perspective by analysing the participants’ discourse in relation to expressions of self-competence (at an individual and group level) concerning the task and group cohesion (task cohesion and social cohesion). This proposal’s potential is illustrated by the empirical results of a case study that analyses social presence during a collaborative work task by university students using the Moodle learning platform.  相似文献
