The purpose of this study is to describe the experiences of lesbian, gay, bisexual, transgender, questioning, intersex, two spirit, and queer (LGBTQ+) youth with school-based sexuality education (SBSE), as well as to document strategies LGBTQ+ youth are using to address their evolving and specific sexual health needs outside of SBSE. Researchers conducted focus groups with 17 adolescents (ages 14–18) from urban and suburban Midwestern cities. Results of this study indicate LGBTQ+ youth find SBSE to be heteronormative, cisgender focused, and primarily focused on pregnancy and disease prevention, which contributes to LGBTQ+ youth experiences of exclusion. In response to SBSE that did not meet student needs, participants reported seeking sexual health information outside of SBSE. Other sources included family and other trusted adults, the Internet, and community resource centers. Students reported variable rates of use and trustworthiness across these resources. Results of this study suggest that school personnel should consider alternatives to traditional SBSE models to meet the needs of LGBTQ+ youth, and that an important part of SBSE should include guidelines for Internet safety. 相似文献

Little is known about the transmission of vibration to the head when using whole-body vibration (WBV) training machines. This paper investigates the effect of frequency and posture on the transmission of vibration from a vibrating plate to the head of standing people. Nine male participants were exposed to vertical vibration at nine frequencies in the range of 17–46 Hz and vibration acceleration in the range of 7.85–18.64 m/s2 (peak). The participants adopted four standing postures described as standing with locked knee (LK), bent knee (BK), one leg (OL), and one foot to the front and the other to the back (FB). The transmissibility to the head differed among postures (t-test, p < 0.05) and was greatest with the FB posture and smallest with the BK posture. The transmissibility to the head decreased with increasing the frequency (t-test, p < 0.05) but the extent of the decrease depended on the adopted posture. This frequency-posture interaction effect on the transmissibility should be considered when designing a training program. The data will be useful for developing standards/protocols that govern the use of WBV machines as well as for building human body models that can predict potential risks arising from using WBV machines. 相似文献

This empirical research was conducted to investigate the role of transformational leadership, organizational culture and organizational learning in improving the performance of Iranian agricultural faculties and leading them to become learning organizations. The research population consisted of all faculty members of public agricultural faculties affiliated with Iran’s Ministry of Science, Research and Technology. A sample of 329 faculty members was selected using stratified random sampling method with proportional allocation. Questionnaire was the main tool for data gathering. Validity of the questionnaire was verified using average variance extracted. Composite reliability coefficients were calculated for determining the reliability of the questionnaire. Collected data were analyzed by structural equation modeling technique using Lisrel 8.50 software package. The results showed that there was a positive and significant relation between contextual components (transformational leadership and learning organizational culture) and process component (organizational learning). These two contextual components could explain 87.3 % of the process component variance. Also, there was a positive and significant relation between process component and performance component, and the process component could explain 36 % of the performance component variance. Our findings support that transformational leadership and learning organizational culture with the effect on organizational learning process not only improve the agricultural faculty performance, but also change them to learning organizations. 相似文献

The following research approximated how the central nervous system of Paralympic wheelchair athletes resolve kinematic redundancies during upper-limb movements. A multibody biomechanical model of a tetraplegic Paralympic athlete was developed using subject-specific body segment parameters. The angular joint kinematics throughout a specified Paralympic sport movement (i.e., wheelchair curling) were experimentally measured using inertial measurement units. The motor control system of the Paralympian was mathematically modelled and simulated using forward dynamics optimization. The predicted kinematics from different optimization objective functions (i.e., minimizing resultant joint moments, mechanical joint power, and angular joint velocities and accelerations) were compared with those experimentally measured throughout the wheelchair curling movement. Of the optimization objective functions under consideration, minimizing angular joint accelerations produced the most accurate predictions of the kinematic trajectories (i.e., characterized with the lowest overall root mean square deviations) and the shortest optimization computation time. The implications of these control findings are discussed with regards to optimal wheelchair design through predictive dynamic simulations. 相似文献

AbstractThe theory of planned behavior has received significant attention more recently. This study used a survey to apply the theory of planned behavior to predict the Internet utilization behavior among 214 undergraduate agricultural students in Iran. Coefficient correlations and linear regressions were employed to analyze relationships among constructs. Results revealed that subjective norm and intention were the strongest predictors of the Internet utilization behavior, which explained 57% of the variance. Perceived behavioral control was the most significant predictor of the Internet use intentions. Subjective norms, to a lesser degree also had important influences on intention. Attitude did not surface as an effective direct predictor of the Internet utilization behavior. Finally, the theory of planned behavior was supported as an effective model explaining the Internet utilization behavior. The most prevalent reason to stop using the Internet was that they were experiencing problems getting access to the Internet. 相似文献

A descriptive-comparative study of performance characteristics in futsal players of different levels
Naser Naser 《Journal of sports sciences》2016,34(18):1707-1715
Despite the increasing popularity of futsal, there is little information on performance characteristics of players. We aimed to determine the validity and reliability of a futsal shooting test and to evaluate and compare performance characteristics of three futsal playing levels. Twenty-four males (n = 8 elite, n = 8 semi-elite, n = 8 social) completed two trials to examine the reliability of the Massey Futsal Shooting Test (MFST) and to compare various fitness characteristics between groups. MFST time taken (P = 0.010), shot speed (P < 0.001) and points scored per shot (P < 0.001) were better for elite relative to social players. Test–retest reliability was acceptable for all groups, but it was most repeatable in elite players. Loughborough Soccer Passing Test performance was better in elite relative to social players (P = 0.004). There were no differences in countermovement-jump height between groups. Elite players ran faster over 5 m than both semi-elite (P = 0.043) and social (P = 0.002) and faster than the social players through 10 m (P = 0.028) and 20 m (P = 0.026). Distance covered in the Futsal Intermittent Endurance Test was higher in elite relative to semi-elite (P = 0.005) and social (P < 0.001) groups. The MFST is a valid and reliable protocol to assess futsal shooting-skill performance; elite players have superior shooting and passing skill and have greater sprinting and intermittent-running ability. 相似文献

AbstractThis article reports on a research project undertaken at a university in Iran to study the impact of academic libraries consortium on research productivity. The overall objective of study was to examine to what extent the subscribed resources meet the needs of users and to determine the quality of cited journals by researchers. It also examined the relationship between the access method to a cited journal, its quality and the average citing to it. The results of the present research can help decision makers for selecting and providing suitable resources and databases based on the users' needs. 相似文献

To address the need for students to better comprehend process management concepts in an undergraduate-level operations management course, we proposed and examined the effectiveness of an experiential learning activity, the Service Process Observation Exercise (SPOE). After teaching process management topics in the form of a traditional lecture, students were offered the opportunity to observe, record, and analyze a live, functioning process and to report their findings. Analyzing exam results following the activity, we found that the students who participated in the SPOE scored 5.3% higher than students who did not participate on items measuring knowledge of process management concepts. No differences were found on items measuring the knowledge of other concepts covered in the course. These findings are robust, even after controlling for potential covariates, suggesting that the SPOE significantly improves student comprehension of concepts directly related to process management. 相似文献

Gender and sexually diverse (GSD) students face unique challenges in schools due to the privileging of cisgender and heterosexist norms in these settings. In particular, GSD youth who belong to ethnically and racially minoritized groups face further challenges within school environments that disregard their cultural contexts and intersectional identities. It is important for school psychologists to ensure safe and high-quality mental health, educational, and behavioral supports for these students. One possible avenue for building these types of supports is through school consultation. When school psychologists collaborate with other professionals in a culturally competent, participatory way, their work has the potential to bolster behavioral, academic, and mental health outcomes at the individual, group, and/or systems levels. Adapting Ingraham's multicultural school consultation model, this article proposes a multicultural, GSD affirming school consultation framework that also approaches the experiences of racially and ethnically minoritized individuals through the lenses of intersectionality and minority stress frameworks. Across its five domains, this adapted framework aims to give practitioners and researchers a conceptual foundation to support GSD students of minoritized ethnic and racial identities by considering interactions among consultants, consultees, and clients within their wider school contexts. 相似文献
