Adolescent success providing satisfying support in response to a close friend's call in a caregiving task was examined as a potentially fundamental developmental competence likely to predict future social functioning, adult caregiving security, and physical health. Adolescents (86 males, 98 females; 58% White, 29% African American, 8% mixed race/ethnicity, 5% other) were followed from ages 13 to 33 (1998–2021) using multiple methods and reporters. Early caregiving success was found to predict greater self- and partner-reported caregiving security, lower negativity in adult relationships, and higher adult vagal tone. Results are interpreted as advancing our understanding beyond simply recognizing that adolescent friendships have long-term import, to now identifying specific capacities within friendships that are linked to longer-term outcomes. 相似文献

Floating is the act of staff moving from one unit to another based on the needs of the patients in a hospital. Many staff who float to different units express negative feelings, including anxiety and lack of self‐efficacy. However, floating is an economical and efficient method to use staff across the hospital, especially with current staffing shortages in the United States. This study investigated how the use of mobile performance support devices may help reduce anxiety and increase self‐efficacy for staff who float to different units. With access to multiple resources available on mobile devices, Bandura's social learning theory and self‐efficacy concept set the framework through modeling, observing, and imitating others in order to reproduce certain behaviors and tasks and believe in one's capability to perform. A quantitative study incorporating the retrospective pretest‐posttest design was conducted using the population of float staff, both nurses and respiratory therapists, from Children's Medical Center of Dallas. Both the State‐Trait Anxiety Inventory and General Self‐Efficacy Scale, along with a basic demographic tool, were used to explore anxiety and self‐efficacy in relation to the use of mobile performance support devices. Findings can be used to alleviate the negative feelings of staff toward the idea of floating. 相似文献

Abstract Interactive museum exhibits are ubiquitous in science centers, and are becoming increasingly popular in art, history and cultural museums. At an interactive exhibit, visitors can act on the exhibit and the exhibit reacts. While there is much theoretical and empirical support for the idea that interactive features promote science learning, we believe that serious design problems can arise if an uncritical “more is better” approach is taken to interactivity. This article describes five common pitfalls of designing exhibits with high levels of interactivity or multiple interactive features: 1) multiple options with equal salience, 2) features allowing multiple users to interfere with one another, 3) options that encourage users to disrupt the phenomenon being displayed, 4) features that make the critical phenomenon difficult to find, and 5) secondary features that obscure the primary feature. Examples of each of the five problems are presented, and possible design solutions are offered. 相似文献
