The role of the principal is imperative in creating a school climate that nurtures differences and equality at the same time. Policy and legislation in Ireland dictates the responsibility of school principals in preventing and intervening in issues relating to bullying. The current research investigates the extent to which principals consider the impact of bullying on their students and the strategies they take to combat it in their schools. We consider how principals respond to bullying and what supports they feel are missing for them to adhere to relevant policy. A sample of 918 principals from a range of schools across Ireland completed an online survey. The results demonstrated some positive actions by principals such as the provision of anti-bullying policies. However, they also document areas that need more action such as increased access to counsellors and appointing a specific staff member to deal with and tackle bullying in each school. Guidance from the Department of Education and Skills in Ireland on the development and provision of an anti-bullying programme is called for. Results are discussed in light of the current Anti-Bullying Procedures established by the Department of Education and Skills and the Action Plan for Bullying 2013.  相似文献

This study seeks to determine if the same five bipolar factors that appear for the ideal role concepts of public school teachers also appear for parochial school teachers. Subjects included 185 teachers from a Catholic diocese. The data were factor analyzed by means of a principal axis analysis with varimax rotation. An analysis of variance was used to compare the factor analyses. The results indicated that parochial and public school teachers have similar factor structures. When comparing factor scores of the two groups, there were significant differences on several factors, indicating that parochial school teachers adopt a more facilitating role than do public school teachers.  相似文献

The Student Counselling Needs Scale (SCNS) was administered to 867 participants recruited from high schools in Kenya. The data were analyzed using exploratory factor analysis yielding five factors: human relationships, career development, self development, social values, and learning skills were assessed. The findings highlighted the importance of using assessment instruments to identify students’ counselling needs in Kenya.  相似文献

Abstract

The aims of this study were: (1) to characterize selected fitness and health attributes of two types of habitual recreational off-road vehicle riders – off-road motorcyclists and all-terrain vehicle riders; (2) to explore differences among riders in terms of vehicle type, age, and gender; and (3) to compare the fitness and health of riders to population norms and clinical health standards. Canadian off-road riders (n = 141) of both sexes aged 16 years and over were recruited through local and national off-road riding organizations. Anthropometry, fitness, and health measures of off-road motorcycle and all-terrain vehicle riders were compared with population norms, health standards, and physical activity guidelines. Off-road motorcycle riders had above average aerobic fitness (79th percentile), while all-terrain vehicle riders were lower than average (40th percentile). All riders had a healthy blood lipid profile and a low incidence of the metabolic syndrome (12.9%) compared with members of the general population. Off-road motorcycle riders had healthier body composition and fitness than all-terrain vehicle riders; however, the body composition of off-road motorcycle riders was no healthier than that of the general population and all-terrain vehicle riders were worse than the general population. Off-road motorcycle riders had healthier anthropometry and fitness than all-terrain vehicle riders and thus fewer health risk factors for future disease, demonstrating that the physiological profiles of off-road riders are dependent on vehicle type.  相似文献

Numerous classroom-based interventions have aimed to improve sexual health outcomes for young people, yet few have shown strong, lasting effects. Ecological approaches that address multiple levels of a young person’s environment offer largely untapped potential to positively change sexual behaviour. This paper presents results of a cluster-randomised trial of a multicomponent sexuality education intervention that integrated a classroom curriculum, parent education workshops and materials, peer advocate programme, and sexual health services at 10 urban high schools. An implementation evaluation, employing quantitative and qualitative instruments, was conducted to examine whether the individual components of the intervention were delivered as planned and how they were received by the target populations. Multilevel modelling was used to evaluate the effect of the multicomponent intervention on outcomes at one-year follow-up. Results showed that the intervention components were successfully implemented with and well received by target populations. Students receiving the multicomponent intervention reported greater increases in the use of sexual health services (odds ratio [OR] = 1.73, 95% CI = 1.09–2.75) and the likelihood of carrying a condom (OR = 2.71, 95% CI = 1.44–5.09) relative to those receiving a control condition. No effects were found for other behaviours, possibly due to low prevalence of sexual activity in the sample and the small number of schools randomised.  相似文献

Most students participating in science undergraduate research (UR) plan to attend either medical school or graduate school. This study examines possible differences between premed and non-premed students in their influences to do research and expectations of research. Questionnaire responses from 55 premed students and 80 non-premed students were analyzed. No differences existed in the expectations of research between the two groups, but attitudes toward science and intrinsic motivation to learn more about science were significantly higher for non-premed students. Follow-up interviews with 11 of the students, including a case study with one premed student, provided explanation for the observed differences. Premed students, while not motivated to learn more about science, were motivated to help people, which is why most of them are pursuing medicine. They viewed research as a way to help them become doctors and to rule out the possibility of research as a career. Non-premed students participated in research to learn more about a specific science topic and gain experience that may be helpful in graduate school research. The difference in the reasons students want to do UR may be used to tailor UR experiences for students planning to go to graduate school or medical school.  相似文献

Weanling rats were tested for retention of an aversion to a novel flavor (chocolate milk) that had been conditioned as a single-element conditioned stimulus (CS) or in compound with a novel ambient odor (banana). The presence of the ambient odor during conditioning had no effect on flavor aversion shortly thereafter, confirming previous results. The flavor aversion observed 21 days after conditioning, however, was significantly stronger for pups conditioned with the single-element CS than for those given the flavor-odor compound as the CS. This retention effect was due to a surprisingincrease in the conditioned aversion observed 21 days after conditioning with the single-element CS. A second experiment confirmed this paradoxical increase in retention of the aversion to chocolate milk. This experiment also verified that no such increase occurred in retention of the conditioned aversion to a different flavor (saccharin), whether the initial aversion was strong or weak. The results may be explained in terms of generalized latent inhibition from consumption of mother’s milk.  相似文献
