National longitudinal databases hold much promise for school counseling researchers. Several of the more frequently used data sets, possible professional implications, and strategies for acquiring training in the use of large‐scale national data sets are described. A 6‐step process for conducting research with the data sets is explicated: determining research questions, accessing the data set, understanding the study's sample design, determining an analytic sample, considering pertinent data analysis issues, and understanding the limitations of using the data sets. Suggestions for preparing school counseling researchers and potential themes for future research are outlined.  相似文献

Contingent self-esteem (CSE) describes the degree to which self-esteem is dependent on meeting day-to-day appraisals from oneself and others. This will vary between individuals, ranging from lower to higher CSE. A lower CSE is related to a range of adaptive social and emotional outcomes in adolescents and young adults. This study explores children’s CSE and how this associates with behavioural outcomes. A total of 280 children between the ages of 9 and 11 years completed a composite questionnaire on aspects of their self-esteem and behaviour. Children’s class teachers completed behavioural outcome questionnaires for a random sample of 100 of these children. Based on teachers’ and children’s scores, high levels of global self-esteem were associated with lower CSE and fewer behavioural difficulties. CSE domains of social feedback and physical appearance retained significant associations with behavioural outcomes after controlling for global self-esteem. This may relate to the degree that children depend on the perceived evaluations of others. Implications for educational psychologists are highlighted.  相似文献

This article presents results from an innovative social work field education program, which prepares BSW and MSW students to work in interdisciplinary teams with congregational nurses as they serve persons age 55+ or older. The Congregational Social Work Education Initiative is a field education project based on an applied interdisciplinary model, whereby social work students at the graduate and undergraduate level partner with congregational nurses to serve at-risk members of congregations and religious affiliated organizations (RAOs). Students and nurses provide free health, mental health, and wellness services to address individual, family, group, and community health, mental health, and housing issues. Funded by community health foundations, it trains BSW and MSW students for professional practice in congregational and community religious affiliated settings through interdisciplinary and collaborative methods. Information on the development of the model and case illustrations are provided so other social work educational programs and congregational nurse programs might duplicate its success.  相似文献

Artificial rugby union playing surface installation is increasing. This prospective cohort study aimed to examine the effect of playing surface on match injury types within 157 players of two UK professional rugby union clubs playing 209 matches (96 on artificial surfaces and 113 on grass) over three seasons. There was no difference in overall injury risk between the two playing surfaces with injury incidence on artificial 80.2 (CI 69.9–91.7) and on grass 81.9 per 1000 match-hours (CI 72.2–92.5), with an incidence rate ratio (RR) of 0.98 (CI 0.82–1.17). There was a higher rate of concussion (RR 0.52, CI 0.34 – 0.78) and chest injuries on grass (RR 0.26 CI 0.07, 0.95), and a higher rate of thigh haematoma (RR 2.25, CI 1.05–4.82) foot injuries (RR 4.12, CI 1.10, 15.40) and injury to players being tackled (RR 1.46, CI 1.00, 2.15) on artificial. Whilst there was no higher injury risk for matches played on artificial versus natural grass surfaces, the higher incidence of concussion and chest injury on grass, and the higher rate of foot injuries on artificial surfaces may be related to tackle and footwear-to-surface interface factors.  相似文献

Abstract

In two experiments, participants performed visual detection, visual discrimination and decision-making tasks, in which a binary (left/right) response was required. In all experimental conditions, a spoken word (“left”/“right”) was presented monaurally (left or right ear) at the onset of the visual stimulus. In Experiment 1, 26 non-athletes located a target amongst an array of distractors as quickly as possible, in both the presence and absence of spoken cues. Participants performed superiorly in the presence of valid cues, relative to invalid-cue and control conditions. In Experiment 2, 42 skilled netballers completed three tasks, in randomised order: a visual detection task, a visual discrimination task and a netball decision-making task – all in the presence of spoken cues. Our data showed that spoken auditory cues affected not only target detection, but also performance on more complex decision-making tasks: cues that were either spatially or semantically invalid slowed target detection time; spatially invalid cues impaired discrimination task accuracy; and cues that were either spatially or semantically valid improved accuracy and speeded decision-making time in the netball task. When studying visual perception and attention in sport, the impact of concomitant auditory information should be taken into account in order to achieve a more representative task design.  相似文献

IN THIS COLUMN, THE AUTHOR EXAMINES RECENT RESEARCH ON TWO SEPARATE TOPICS: 1) breastfeeding; 2) postpartum length of hospital stay. Recent studies suggest long-term effects of breastfeeding that benefit both mother and infant. Benefits include a reduced risk of breast cancer in breastfeeding mothers and a reduced level of total and LDH cholesterol in adults who were breastfed as infants. Infants of mothers with maternal asthma had lower rates of asthma if the mother breastfed. In a study of women in the United States who planned to breastfeed, those mothers who breastfed exclusively and planned to breastfeed more than three months were more likely to achieve their goals than mothers who planned to combine breast and human-milk substitute feeds and to breastfeed less than three months.In a Canadian study, shortened postpartum stays led to increased re-admission to hospital for mothers with cesarean births. In contrast, in a Massachusetts study, shortened postpartum stays did not lead to an increase in infant visits for urgent care. However, the Massachusetts study did not reflect a decrease in maternity-related costs associated with shortened length of postpartum stay.  相似文献

Herman Witkin's research in differentiation theory proposed a conceptual framework describing the cognitive style known as field dependence‐independence. The operational measures of this construct are restructuring skills and interpersonal competencies, and were originally conceived to be fixed in an individual. A recent reconceptual‐isation, however, suggested that there may be some malleability in learning strategies that flow from cognitive style. Learners predisposed to field dependence might gain access to restructuring skills brought to problem‐solving situations by field independents. This study undertook to examine the effects and practicability of restructuring training as a means of addressing individual learner differences. Field independent subjects significantly out‐scored field‐dependent subjects on all three test tasks in the control group. Experimental group field independents did not significantly outscore experimental field dependents. Training enhanced field dependent subject performance on two dependent measures tasks. There was interaction across treatment and field dependence on all three dependent measures.  相似文献
