Creation of a faculty database is a challenging but worthwhile project. In 2002, librarians at the University of Missouri-Columbia were approached by the School of Medicine to create a database of faculty publications. This article outlines the project and gives special emphasis to the problems of author searching. Discussion items include author searching syntax and providing ideas for how to determine if a publication was written by a particular author. 相似文献

This study evaluated whether the relationship between socioeconomic status (SES) and moderate-to-vigorous physical activity (MVPA) is mediated by social support of peers and parents. A cross-sectional study included students (n = 1182) aged 11 to 18 years who were recruited in 2014 from public schools in Fortaleza, Brazil. Participants completed a questionnaire to assess all variables. Mediation analyses were performed to determine the role of parental support and peer support on the relationship between SES and MVPA. Also, moderated-mediation analyses with estimating of conditional indirect effects were performed in order to identify whether gender is a moderator of the mediating effect. A positive and significant association between SES and MVPA was found among Brazilian students, and social support of parents and peers were significant mediators of this relationship. Conditional indirect effects showed that both parental and peer support had a significant indirect effect among boys; only parental support had a significant indirect effect among girls. These results suggest that improving social support can help reduce the impact of SES on physical activity among Brazilian adolescents. 相似文献

There is a limited theoretical and empirical literature on the role of friendship quality and interracial contact on adolescent racial prejudice development. To address this gap, the present study examined the relationship between these factors amongst an Australian sample of 89 school-aged adolescent friendship dyads and 80 university-aged adolescent friendship dyads. All participants were administered questionnaires measuring prejudice towards Asian and Arab Australians, friendship quality and interracial contact. Overall, the results revealed that all adolescents reported significantly higher levels of subtle prejudice than blatant prejudice. As predicted, university-aged adolescents reported significantly lower levels of both subtle and blatant prejudice towards Asian and Arab Australians than school-aged adolescents. Importantly, adolescents who had contact with Asian (outgroup) friends reported significantly lower levels of subtle and blatant prejudice towards Asian Australians than adolescents with no Asian friends. Interestingly, friendship quality was not found to moderate the similarity of prejudice levels within friendship dyads. Together, these findings indicate that in developing subtle prejudice-reduction programs research should focus on increasing interracial cooperative contact, particularly amongst school-aged adolescents. 相似文献

As they learn to navigate the social world, children construct frameworks to interpret others' behavior. The present studies examined two such frameworks: a mentalistic framework, which construes behavior as driven by internal mental states; and a normative framework, which presumes people act in accordance with social norms. Participants included 101 children (ages 4, 7, and 10; 81% White; 41% female) and 35 adults (66% female) tested in the northeastern United States from 2019 to 2021. Children and adults utilized both mentalistic and normative frameworks to explain others' behaviors. Framework use depended on features of the behavior being explained. Minimal developmental differences were observed. The relative independence and the utility of the mentalistic and normative frameworks for naïve reasoning about behavior are considered. 相似文献

Two studies assessed the role of Separate Control of Shared Space (SCoSS) technology in supporting peer collaborative discussion and comprehension. We hypothesised that providing equitable shared input to two literacy tasks (both good predictors of comprehension skill) would support discussion to promote the joint construction of meaning, and hence individual progress. Study 1: 50 7–9‐year‐olds took a reading‐specific multiple classification (RMC) pre‐test, categorising words on two dimensions, before training on the task in pairs using SCoSS, dual‐control or individual technology. Discussion produced more accurate post‐test classification performance and SCoSS was associated with higher frequency of statements during training that combined both RMC dimensions (surface form and meaning of words). Study 2: 12 8–9‐year‐olds were pre‐tested on story recall and worked in pairs on a SCoSS‐supported story construction task, requiring collaborative inference‐making, hypothesis generation and selection. Post‐test story recall was predicted by the frequency of deductive causal statements during training. We discuss how technology can be used to promote collaboration and discussion that supports joint understanding and individual comprehension development. 相似文献

The purpose of this study was to explore methods to enhance mathematical problem solving for students with mathematics disabilities (MD). A small‐group problem‐solving tutoring treatment incorporated explicit instruction on problem‐solution rules and on transfer. The transfer component was designed to increase awareness of the connections between novel and familiar problems by broadening the categories by which students group problems requiring the same solution methods and by prompting students to search novel problems for these broad categories. To create a stringent test of efficacy, we incorporated a computer‐assisted practice condition, which provided students with direct practice on real‐world problem‐solving tasks. We randomly assigned 40 students to problem‐solving tutoring, computer‐assisted practice, problem‐solving tutoring plus computer‐assisted practice, or control, and pre‐ and posttested students on three problem‐solving tasks. On story problems and transfer story problems, tutoring (with or without computer‐assisted practice) effected reliably stronger growth compared to control; effects on real‐world problem solving, although moderate to large, were not statistically significant. Computer‐assisted practice added little value beyond tutoring but, alone, yielded moderate effects on two measures. 相似文献

Although much research has examined the relationship between exercise and affect, few studies have considered the effects of exercise bouts of different durations and few researchers have questioned the longer term effects that might be associated with acute exercise. The aim of this study was to compare the effects of the standard health recommended exercise duration of 30 min with a shorter (15 min) bout of exercise upon individuals' affect scores both during and after exercise. Twenty-three (mean age 22.4 years) physically active participants engaged in two counterbalanced cycle ergometer exercise conditions for 15 min (short bout) and 30 min (moderate bout). The participants completed the Subjective Exercise Experience Scale before, during, 5 min, 30 mins, 1 h and 2 h after both exercise conditions. A series of 2 x 6 within-participant repeated-measures analyses of variance for positive well-being (P <0.01), psychological distress (P <0.01) and fatigue (P <0.01) scores revealed significant time main effects, with improved scores over time. No significant differences were noted between the 15-min and 30-min exercise bouts. These results indicate that positive affective responses are experienced by exercisers after relatively short bouts of acute exercise and these effects can still be evident some time later. 相似文献

This article quantitatively summarizes experimental and quasi‐experimental studies on teaching students with mathematics difficulties (MD) published between 2000 and 2014, research that was available following earlier syntheses. It reports the analysis of effect sizes of 25 intervention studies on participant characteristics, intervention parameters, domains of mathematics interventions, and instructional approaches and components. Results indicate that several participant characteristics (e.g., grade level and level of mathematics difficulties) and intervention parameters (e.g., methodological soundness, intervention agent, and grouping) mediated the treatment effects. In addition, different types of instructional approaches and several instructional components contributed to the improvements in mathematics performance in students with MD. 相似文献

The law of Non-Original Malappropriate Eponymous Nomenclature (NOMEN) states that no phenomenon is named after its discoverer. However, eponymous terms are rife in the anatomical and medical literature. In this viewpoint commentary, the authors discuss the history of anatomical eponyms, explain the additional cognitive load imposed by eponyms that can negatively impact student learning and explore the view that eponyms are “pale, male and stale” in the socially conscious 21st century. The authors probe two of the most common arguments used to keep eponyms in anatomy education: (1) clinicians use them because they are easy, and (2) eponyms remind us of anatomy's history. Educators, clinicians and students need to work together to progress this movement and bring a modern lens to this discussion. Based on the arguments presented in this commentary, the authors propose that eponyms should be removed from anatomy curricula, textbooks and have no place in the anatomy classroom. 相似文献
