Resident assistants (RAs) can serve as important suicide prevention gatekeepers. The purpose of the study was to determine if training improved RAs’ crisis communications skills and suicide‐related knowledge and to determine if the knowledge elements predicted crisis communications skills. New RAs showed significant improvement in all areas from pretest to posttest, whereas returning RAs showed no significant increase in any of the areas. None of the knowledge areas predicted communications skills for either group. 相似文献

Institutions are developing online courses that contain rich multimedia, but research shows there is little difference in student achievement when these types of materials are included. However, many studies report the results of the presence, not the access, of multimedia learning objects. In addition, they do not categorize the multimedia as supplemental or required. To better understand the relationship between multimedia inclusion and student success, this study investigates student access of three categories of supplemental multimedia in an online course and uses access data as a filter for comparing student final grades. A summary of statistically significant differences in mean final grades at four levels of supplemental multimedia access is included. 相似文献

Data are reported from 3 groups of children residing in Bucharest, Romania. Face recognition in currently institutionalized, previously institutionalized, and never-institutionalized children was assessed at 3 time points: preintervention ( n = 121), 30 months of age ( n = 99), and 42 months of age ( n = 77). Children watched photographs of caregiver and stranger faces while event-related potentials were recorded. Results demonstrate that institutionalized children show pervasive cortical hypoarousal in response to faces and that foster care is somewhat effective in remediating this deficit by 42 months of age. All 3 groups of children distinguished between the familiar and unfamiliar faces. These results have the potential to inform an understanding of the role of early experience in the development of the neural systems that subserve face recognition. 相似文献

Three approaches to molecular phylogenetics are demonstrated to biology students as they explore molecular data from Homo sapiens and four related primates. By analyzing DNA sequences, protein sequences, and chromosomal maps, students are repeatedly challenged to develop hypotheses regarding the ancestry of the five species. Although these exercises were designed to supplement and enhance classroom instruction on phylogeny, cladistics, and systematics in the context of a postsecondary majors-level introductory biology course, the activities themselves require very little prior student exposure to these topics. Thus, they are well suited for students in a wide range of educational levels, including a biology class at the secondary level. In implementing this exercise, we have observed measurable gains, both in student comprehension of molecular phylogeny and in their acceptance of modern evolutionary theory. By engaging students in modern phylogenetic activities, these students better understood how biologists are currently using molecular data to develop a more complete picture of the shared ancestry of all living things. 相似文献

This paper reports on research conducted over a two‐year period in a large Educational Psychology Service (EPS) in England. Researchers were keen to ascertain the views of young people and EPS members about young people being directly involved in educational decision‐making and how their genuine involvement in such decision‐making might be best achieved. Focus groups were employed as a means of gathering data which were analysed using Content Analysis. Young people and EPS members ultimately identified “culture”, “attitudes”, “environment”, and “systems” as being the most important factors in ensuring the genuine involvement of young people in decision‐making. 相似文献

The present study investigated the relations between academic self-concepts and the emotions of enjoyment, pride, anxiety, anger, and boredom as experienced in mathematics, physics, German, and English classes (N = 1710; grades 8 and 11). In line with our hypotheses derived from appraisal-based emotion theories and self-efficacy research, within-domain relations between self-concepts and emotions were relatively strong and notably stronger within quantitative domains (mathematics and physics) than verbal domains (German and English). Also consistent with our hypotheses, stronger relations between self-concepts and emotions were observed among older students. Self-concept and emotion relations further differed as a function of the specific emotion assessed, with pride showing the strongest and boredom the weakest relations with academic self-concepts in the four domains assessed. Methodological and educational implications as well as directions for future research are discussed. 相似文献

Abstract The aim of this study was to quantify the anthropometric differences between elite senior Australian rowers and the Australian adult population using three-dimensional (3D) whole-body scanning. The dimensions of senior rowers competing at the 2007–2008 Australian Rowing Championships were compared with those of an age-matched sample of Australian adults. Mass, height, and sitting height were measured before the participants underwent a 3D whole-body scan, with lengths, breadths, girths, cross-sectional and surface areas, and volumes extracted from each scan. Differences in means and variability between the two groups were expressed as standardized effect sizes and ratios of coefficients of variation. Heavyweight rowers were generally much larger than the general population in absolute size, with 3D dimensions and height and mass showing the largest effects. In contrast, lightweight rowers were generally similar or smaller in absolute and proportional size. The dimensions of rowers, especially the lightweights, were also generally less variable than those of the general population. The greatest differences between elite rowers and the general population were seen in dimensions that could not be captured without 3D scanning, such as segmental volumes and cross-sectional areas. 相似文献

Humor ability,unwillingness to communicate,loneliness, and perceived stress: Testing a security theory 总被引:1,自引:0,他引:1
Nathan Miczo 《Communication Studies》2013,64(2):209-226
The purpose of this study was to develop and test a theory of the laughter‐humor link in interpersonal communication. The basic premise of the theory is that a sense of security underlies the ability to encode humor in everyday conversation. It was hypothesized that communication‐related security (i.e., willingness to communicate) predicts humor ability, which in turn negatively predicts loneliness and perceived stress. Undergraduates completed a survey including the following scales: Unwillingness‐ to‐Communicate, Humor Orientation, Coping Humor, revised UCLA Loneliness, and Perceived Stress. Regression analyses confirm that willingness to communicate predicted humor orientation, while humor orientation mediated the relationship between willingness to communicate and coping humor. Humor orientation negatively predicted loneliness and perceived stress, although in both cases willingness to communicate mediated the relationships. The discussion highlights methodological limitations (e.g., use of self‐report) and reiterates the need for interaction‐ and context‐based studies of the laughter‐humor relationship. 相似文献
