This study examined children's and adolescents' narrative accounts of everyday experiences when they harmed and helped a friend. The sample included 100 participants divided into three age groups (7‐, 11‐, and 16‐year‐olds). Help narratives focused on the helping acts themselves and reasons for helping, whereas harm narratives included more references to consequences of acts and psychological conflicts. With age, however, youth increasingly described the consequences of helping. Reasons for harming others focused especially on the narrator's perspective whereas reasons for helping others were centered on others' perspectives. With age, youth increasingly drew self‐related insights from their helpful, but not their harmful, actions. Results illuminate how reflections on prosocial and transgressive experiences may provide distinct opportunities for constructing moral agency.  相似文献

Associations between fundamental movement skills (FMS), perceived competence, enjoyment and physical activity (PA) have not been widely investigated among Chinese school children. We hypothesised that FMS would be directly related to self-reported and objectively measured PA, and indirectly related to these outcomes via perceived physical and movement skill competence, and enjoyment. Participants were 763 primary school children (age = 9.3 ± 1.7 years; 474 girls) across grades. FMS were measured for a subsample (n = 603) using Test of Gross Motor Development-2. PA using accelerometers was obtained from this subgroup (n = 238). All participating children completed a questionnaire measuring their PA participation, enjoyment, and perceived physical and movement skill competence. Structural equation modelling revealed positive associations between locomotor skills and perceived movement skill competence (β = .11, 95% CI [.001, .22]), and between perceived movement skill competence and objectively measured PA (β = .59, 95% CI [.04, 1.14]). Perceived physical competence and enjoyment mediated the association between locomotor skills and self-reported PA (β = .08, 95% CI [.02, .12]), but not objectively measured PA. Given inconsistent findings for subjective and objective measures of PA, further mediation analyses of the association between FMS and PA may be warranted.  相似文献

Small enterprises are facing significant challenges to become suppliers of bigger customers due to the excessive costs associated with accessing a vast market of potential customers. It is essential for small businesses to adopt an ERP system to maintain control of their operations and to compete globally. An ERP implementation is expensive and risky for all businesses, but it is still more challenging for small businesses, which have particular characteristics. We identified from archived literature, key decisions necessary in selecting and implementing an ERP system. While these critical decisions are applicable to all types of businesses, the focus of this research was to recommend the best practices for each one of these key decisions for small businesses. We interviewed six small businesses to recommend best practices for the critical decisions: (1) project team structure, (2) implementation strategy, (3) database conversion strategy, (4) transition technique, (5) risk management strategy and (6) change management strategy. Our results indicate that these best practices greatly enhanced the success of an ERP implementation for small businesses. Further, we recommend studying the impact of ERP systems on the small business’ participation in supply chain management.  相似文献

The purpose of this work was to determine if public communication of science and technology (PCST) has any influence on people's decision to become dedicated to scientific research. For this reason, a national survey involving 852 researchers from all disciplines was conducted in Argentina. The results showed that the factors affecting scientific vocation are many, and that, regardless of differences in gender, age or discipline, the greatest influence on the decision to go into scientific research is exerted by teachers. The analysis also demonstrated that different manifestations of PCST (science books, press articles, audiovisual material, and activities such as visits to science museums) play a significant role in awakening the vocation for science. From these results it may be stated that PCST--in addition to its function of informing and forming citizens--exerts a significant influence in fostering scientific vocation.  相似文献

Like many developed countries, Spain has experienceda growth in the demand for higher education over thelast twenty years, despite diverse economic cycles. Since this demand does not slow down in the mediumterm, the objective of this study is to analyse, fromstatistical labour force sources since 1987, twopotential influences: family characteristics andlabour market signals.The theoretical framework used here is the humancapital theory, which is tested through discretechoice models where the selection process of youngpeople through the education system is considered. Thechief results may be summarised as follows: firstly,family characteristics are important elements in thedemand for higher education, especially the mother'seducation attainment, which is even more determinantthan that of the father. Secondly, the labour marketsignals in Spain have an influence on the demand forhigher education: as a signal of both the opportunitycost of finding a job if not going to university andthe employment expectations for each releVanteducation level.  相似文献

The aim of this study was to determine the effects of long-term professional golf participation on whole-body and regional bone mass and density. Dual-energy X-ray absorptiometry was performed on 15 male professional golfers and 18 sedentary individuals, matched for sex, race, age (29+/-1 and 25+/-1 years, respectively), body mass (79+/-2 and 74+/-2 kg), height (1.78+/-0.01 and 1.77+/-0.02 m) and percent body fat (20+/-2 and 21+/-2%; mean +/- sx). We found that long-term professional golf participation is not associated with significant increments in regional or whole-body bone mass or density. Neither the lumbar spine nor the femoral neck showed any noticeable enhancement of bone mass in professional golfers compared with controls from the same population. The only effect of professional golf participation on regional body composition was a 9% increase in muscle mass in the dominant arm (P < 0.05).  相似文献

This qualitative theoretical study was conducted in response to the current need for an inclusive and comprehensive model to guide the preparation and assessment of teacher candidates for culturally responsive teaching. The process of developing a model of culturally responsive teaching involved three steps: a comprehensive review of the literature; a synthesis of the literature into thematic categories to capture the dispositions and behaviors of culturally responsive teaching; and the piloting of these thematic categories with teacher candidates to validate the usefulness of the categories and to generate specific exemplars of behavior to represent each category. The model of culturally responsive teaching contains five thematic categories: (1) content integration, (2) facilitating knowledge construction, (3) prejudice reduction, (4) social justice, and (5) academic development. The current model is a promising tool for comprehensively defining culturally responsive teaching in the context of teacher education as well as to guide curriculum and assessment changes aimed to increase candidates’ culturally responsive knowledge and skills in science and mathematics teaching.  相似文献

Despite the high stakes attached to students’ performance on assessments of academic writing, we still know little about the challenges students face when composing in academic contexts. To begin to address this problem, two studies were designed with the following aims: to identify and describe the most prevalent types of academic writing at the secondary level, and to characterize the challenges that both English Language Learners (ELLs) and non-English-Language Learners (non-ELLs) experience with this type of writing. Findings from these studies reveal that (1) in the context of New York City schools, exposition/argument is the most prevalent genre assigned as a writing task in secondary classrooms, as well as the most valued; and that (2) while both Intermediate ELLs and non-ELLs articulated Translating (the process of articulating ideas in the conventions of written English) as the most frequent challenge, the two groups differed in the kinds of Translating challenges and in the types and range of other challenges they articulated: ELLs articulated fewer challenges specifically related to the genre of exposition than did non-ELLs. Based on these findings we suggest several new approaches to classroom diagnostic assessment of writing, and raise issues to be considered in these approaches.  相似文献
