The current study examined a process through which parenting during the primary school transition contributes to cardiovascular health in adolescence, a foundational period for adult health trajectories. Using path analyses, social competence was tested as a mediator between parental sensitivity and adolescent health among 884 families. Results indicated that mothers’ and fathers’ sensitivity was associated with increasing social competence from first grade (age 7) to sixth grade (age 12), which was associated with higher awakening cortisol in ninth grade (age 15) and decreasing blood pressure from sixth to ninth grade. Results suggest that social competence mediates associations between childhood parenting and adolescent cardiovascular risk, and may be protective to children's health over time.  相似文献

Discourse on culture is vital to early childhood educators’ understanding of the young child in various socio-cultural experiences in family and community settings. In this article, the author will present a contemporary definition of culture. This article will then discuss the developmental constructs of self-regulation and emotion regulation and how they are acquired by preschool children. The author will then explore the symbolic and behavioral traditions, rituals, beliefs, and artifacts that culturally diverse participants, in an ethnographic study, used to assist their preschool children in acquiring self-regulation and emotion regulation skills. Finally, the author will present recommendations for early childhood educators and teacher educators that reflect a respectful cultural attunement among educators, children and families.  相似文献

In this article we describe an instance of free‐choice learning in the context of an eelgrass mapping and stewardship project (the Project) that covers over 500 kilometers of coastline in British Columbia, Canada, and involves 20 volunteer groups. In this ethnographic case study we sought to (a) explicate the relationship between individual and collective learning in this free‐choice setting and (b) understand how a network of Project participants could both constitute a free‐choice learning setting and support such a setting. We articulate a dialectic relationship between individual and collective learning, which, unfortunately in our view, has not yet been explored in educational research. In this relation, collective learning fosters individual learning and vice versa, whereby individuals produce resources in action and as outcomes of their activities. These resources expand the action possibilities of the collective, and thus constitute learning. The stability of the network of Project participants, which brings about and supports collective and therefore individual learning, rests on the flexibility of the Project that enables local innovation and tailoring of mapping activities as well as access to expertise and tools produced by other groups and Project partners. The possibilities that arise in the Project for local people to participate in relevant ways constitute free‐choice learning settings.  相似文献

Children's representations of counterintuitive phenomena can be better understood if we take into account the following: (1) Children may develop a conceptual slot for "counterintuitive+real" phenomena, (2) Notions of "reality" in early children's handling of fiction. (4) Cultural systems of religious representations make particular demands on developmental processes.  相似文献

Alterations in joint mechanics have been associated with common overuse injuries. An increase in running cadence in healthy runners has been shown to improve several parameters that have been tied to injury, but the reorganisation of motion that produces these changes has not been examined. The purpose of this study was to determine if runners change their segment coordination and coordination variability with an acute increase in cadence. Data were collected as ten uninjured runners ran overground at their preferred cadence as well as a cadence 10% higher than preferred. Segment coordination and coordination variability were calculated for select thigh–shank and shank–foot couples and selected knee mechanics were also calculated. Paired t-tests were used to examine differences between the preferred and increased cadence conditions. With increased cadence, there was a decrease in peak knee flexion and a later occurrence of peak knee flexion and internal rotation and shank internal rotation. Segment coordination was altered with most changes occurring in mid-late stance. Coordination variability decreased with an increase in cadence across all couples and phases of gait. These results suggest examination of coordination and its variability could give insight into the risk of intervention-induced injury.  相似文献

College students represent an important population for studying and understanding factors that influence sexual risk given the populations' high risk of sexually transmitted infections and unintended pregnancies. Using a quasi-experimental design, the efficacy of a brief and theory-driven mobile application intervention designed to decrease sexual risk behaviors among young college students (N = 118) was tested. Ninety-six percent (n = 114) of the participants showed an increase in contraceptive use knowledge from pretest to posttest (p = .013). Participants did not show a statistically significant change in intention to reduce sexual risk behaviors or actual risk reduction. This study supports the use of technology to educate college students about sexual health.  相似文献

This article describes a dual-case study that was conducted to examine the effects of The Tools Approach on kindergarten students’ use of and interest in informational text. Children in one teacher’s kindergarten classroom during two subsequent years participated in a writing intervention which included learning about text features, conducting group research, and conducting individual research. During both cases, data were collected during child, parent, and teacher interviews. The results of this study showed that children participating in The Tools Approach strategy increased their abilities to identify and use text features to gather and disseminate information. Children also demonstrated increased interest in reading and writing informational text as a result of their participation in the study.  相似文献

The appropriate role for the United Nations in international dispute resolution is a matter of high profile discussion and controversy. This paper begins with this ambivalence about the appropriate role for the United Nations in the world and examines several sets of issues that relate to the future of support for the UN within the US and the prospects for global governance more generally. First, we briefly review two thematic strands in previous and contemporary scholarship:(1) arguments for increased global governance in contemporary world affairs, driven by perceptions of the changing nature of the political, social, economic and military challenges in the contemporary world system. This debate is also put in the context of the relevance of public support for global governance institutions; and (2) why it is valuable to study how the current generation of adolescents perceive issues of global governance and the impact that their views may have on that nexus in the coming years. We then move to an analysis of data generated from an experimental study of American adolescents and their attitudes toward global governance.  相似文献

The research reported in this study examines the very first time the participants planned for and enacted science instruction within a “best-case scenario” teacher preparation program. Evidence from this study indicates that, within this context, preservice teachers are capable of implementing several of the discursive practices of science called for in standards documents including engaging students in science investigations and constructing evidence-based explanations. The participants designed experiences that allowed their students to interact with natural phenomena, gather evidence, and craft explanations of natural phenomenon. The study contends that the participants were able to achieve such successes due to their participation in a teacher education program and field placement, which were designed using a comprehensive, conceptual framework. Video of the participant’s teaching and annotated self-analysis videos served as the primary data for this study. Implications for future research and elementary science teacher education are discussed.  相似文献
