Research Findings: In the present meta-analysis, information from 21 studies (representing 22 separate samples) was pooled across a 10-year period (1998–2008). Across 2 primary dimensions of direct father involvement (frequency of positive engagement activities and aspects of parenting quality) and 5 dimensions of children's early learning (representing social and cognitive domains), findings revealed small to moderate associations. Among group differences tested to further explain the relationships between these constructs, residential status and the ethnic/racial identification of fathers' surfaced as significant moderators, whereas income status was only meaningful at the trend level. Practice or Policy: In recent years, national attention has increased concerning the important influence of fathers on children's development. Concurrently, national interest has turned to the early childhood period as marking a major transition for young children, during which children are confronted with new and diverse developmental challenges that require emotional, social, and cognitive competence across their home and school environments. Although there is a growing body of research on fatherhood and father involvement, this literature has not been examined systematically to determine the strength of associations between specific dimensions of father involvement and young children's early learning that could inform the efforts of early childhood practitioners and family engagement programming decisions. 相似文献

Drawing from resilience theory, we explored the strategies that Mexican immigrant youth used to cope with stressors from being undocumented. On the basis of semi-structured interviews with 30 high school students who emigrated from Mexico to the United States, we identified several stressors from being undocumented, including having limited opportunities, fear of deportation, and exposure to negative reminders of their undocumented status. To manage such stressors, students utilized individual coping strategies (e.g. diversion, reframing, normalizing). In addition, the families of undocumented youth employed various coping strategies to help buffer their children against stressors from being undocumented (e.g. protecting the family unit, positive future, emotional support, limited communication). From our findings, we developed a preliminary model that describes the stress and coping of the undocumented youth in this study, which can extend past theorizing on resilience and thriving, as well as inform the design of community-based programs and policies for undocumented youth and their family. 相似文献

Abstract This paper describes the ActionWorkflow? approach to workflow management technology: a design methodology and associated computer software for the support of work in organizations. The approach is based on theories of communicative activity as language/action, developed in a series of systems for coordination among users of networked computers. This article describes the approach, gives an example of its application, and shows the architecture of a workflow management system based on it. 相似文献

This study used an individual structured interview to (1) verify the incidence of non-anthropocentric reasoning in 123 children attending the 3rd and 4th years in three primary schools in the Lisbon area (Portugal), when they are confronted with ecological dilemmas and (2) establish those places they frequented which permit animal contact. The results show a greater incidence of non-anthropocentric reasoning than that obtained in other international studies. This may be related to the focus of the questions asked, which invited children to imagine themselves as another animal or to present situations where human interaction is unfair. This incidence was found independently of gender, school origin and whether or not pets were owned, even with the more biologically complex animals. School year was the only variable proven to make a difference in conceptually more demanding questions. We also verified that the children's general past experience of nature is essentially aligned to ‘controlled environments depending on ongoing human management’, confirming a decline in direct contact with ‘natural and semi-natural environments’. However, this type of experience does not seem to exert a negative influence on their non-anthropocentric reasoning. 相似文献

RESUMENLa investigación descrita en este artículo se centra en las críticas al enfoque estructural piagetiano y su postulado logicista. En su lugar, se aboga por un enfoque procedural encaminado al descubrimiento de estrategias y procesos cognitivos involucrados en la realización de tareas. Los sujetos fueron 240 niños que asistían a clases de tercero y octavo de EGB. La discusión de los resultados se realiza en términos de procesamiento de la información, esbozándose además un modelo teórico-evolutivo para ese estadio, así como una argumentación crítica en torno al logicismo. 相似文献

Over a decade ago the UK government launched its gifted and talented education policy in England, yet there has been very little published research which considers how schools and teachers are interpreting and implementing the policy. By seeking the views of the gifted and talented co‐ordinators (For ease of reference, the term gifted and talented (G&T) co‐ordinator is used throughout the paper as a generic shorthand for the research participants who were either designated school gifted and talented co‐ordinators or teachers or head teachers with responsibility for policy implementation) with responsibility for addressing the requirements of the policy, the study reported in this paper explored how primary schools in England responded to the policy. Drawing on data gathered using questionnaires with a national sample of primary schools as well as follow‐up in‐depth interviews with a sample of G&T co‐ordinators, the authors report their findings. The study found that there was considerable unease about the concept of identifying and ‘labelling’ a group of pupils as ‘gifted and talented’. G&T co‐ordinators found it difficult to interpret the policy requirements and were responding pragmatically to what they considered to be required by the government. Curriculum provision for the selected group of gifted and talented pupils was patchy. The paper concludes by identifying a need for further professional development for teachers and by challenging the policy's over‐emphasis on identifying and labelling gifted and talented pupils. We posit whether the gifted and talented education policy would have been better introduced and enjoyed greater success by leaving the identification of pupils to one side and by placing greater emphasis on developing effective learning and teaching strategies instead. 相似文献

Reproducibility of frequency content from surface electromyography (sEMG) signals has not been assessed and it is unknown if incremental load testing design could affect sEMG in cycling. The goals of this study were to assess the reproducibility of measures from sEMG frequency content between sessions and to compare these frequency components between a ramp and a step incremental cycling test. Eighteen cyclists performed four incremental load cycling tests to exhaustion. Two tests were performed using a step increment (load started at 100 W for 3 min followed by increments of 30 W every 3 min) and two were performed using a ramp increment (load started at 100 W for 1 min followed by increments of 30 W·min?1). sEMG was monitored bilaterally for the rectus femoris and vastus lateralis throughout the tests and converted into overall activation (whole signal bandwidth), high- and low-frequency contents. The reproducibility of the frequency content ranged from none to strong (ICC = 0.07–0.90). Vastus lateralis activation was larger at the step compared to the ramp test (P < 0.01), without differences for rectus femoris (P = 0.22–0.91) and for the high-frequency (P = 0.28–0.95) and low-frequency contents (P = 0.13–0.94). sEMG from vastus lateralis and rectus femoris presented none to strong reproducibility. Vastus lateralis is more activated in step test design. 相似文献

Executive functions (EF) are a set of processes that allow individuals to plan, monitor and organize tasks and thus play a key role in the development of reading and maths skills. Environmental factors such as socioeconomic level (SEL) influence reading and maths skills as well as EFs. The aim of this study is to explore the extent to which executive functions play a mediating role between SEL and reading and maths performance. To this end, we assessed 286 Chilean primary education students: 86 with a high SEL and 200 with a low level. The results show that the high-SEL group obtained consistently higher scores than their peers with low SEL levels in both reading and maths tasks as well as in EF measurements. This suggests that SEL could influence the development of these variables. The results also showed that EFs partially mediate the relation between SEL and reading and maths skills in primary school students through the specific function of inhibition. The results are discussed in light of the effect of SEL on the development of EFs and school learning. 相似文献

Knowledge management (KM) is based on contextual factors of the organization, such as human resources, organizational culture, and organizational structure, developed separately by the organizations. This research aims to identify clusters for the development of these contextual factors. The research was based on an instrument containing questions that evaluate the degree of development of the contextual factors of the organization. We collected data from 78 companies of the Brazilian automotive industry, and analyzed them from multivariate techniques of factor analysis, cluster analysis, and discriminant analysis. The research results present four distinct clusters for the development of the contextual factors that support KM. The mapped clusters indicate that a small group of companies are innovative and explorative of knowledge and lead the industry’s creative process, while the other two groups, called exploitative and retardative companies, follow the development proposed by the companies of the two first groups. 相似文献
