Sports participation has been shown to positively affect youth well-being. However, research has also shown that sports environments can be unsafe for lesbian, gay, bisexual, transgender, and queer (LGBTQ) youth. Using data from a large study on school-related experiences of LGBTQ secondary students who reported on their extracurricular activities in school, (N = 15,813), this study examined LGBTQ youth's participation in school sports, the effects of participation on well-being and school belonging, and whether any such benefits of participation varied by transgender status and gender binary identity. Over a quarter of LGBTQ respondents in our study had participated in school sports, and being transgender and being nonbinary were related to a lower likelihood of sports participation. Transgender males and transgender nonbinary youth had the lowest likelihood of sports participation. In general, LGBTQ youth who participated in sports had increased well-being and greater school belonging. However, in regard to self-esteem, transgender nonbinary youth appeared to have greater benefit from participating in sports than did their transgender male and transgender female peers. Considering these results, schools have a responsibility to ensure that school sports are safe and welcoming for LGBTQ youth.  相似文献

Background: Despite decades of research, bullying in all its forms is still a significant problem within schools in Australia, as it is internationally. Anti-bullying policies and guidelines are thought to be one strategy as part of a whole school approach to reduce bullying. However, although Australian schools are required to have these policies, their effectiveness is not clear. As policies and guidelines about bullying and cyberbullying are developed within education departments, this paper explores the perspectives of those who are involved in their construction. Purpose: This study examined the perspectives of professionals involved in policy construction, across three different Australian states. The aim was to determine how their relative jurisdictions define bullying and cyberbullying, the processes for developing policy, the bullying prevention and intervention recommendations given to schools and the content considered essential in current policies. Sample: Eleven key stakeholders from three Australian states with similar education systems were invited to participate. The sample selection criteria included professionals with experience and training in education, cyber-safety and the responsibility to contribute to or make decisions which inform policy in this area for schools in their state. Design and methods: Participants were interviewed about the definitions of bullying they used in their state policy frameworks; the extent to which cyberbullying was included; and the content they considered essential for schools to include in anti-bullying policies. Data were collected through in-depth, semi-structured interviews and analysed thematically. Findings: Seven themes were identified in the data: (1) Definition of bullying and cyberbullying; (2) Existence of a policy template; (3) Policy location; (4) Adding cyberbullying; (5) Distinguishing between bullying and cyberbullying; (6) Effective policy; and (7) Policy as a prevention or intervention tool. The results were similar both across state boundaries and also across different disciplines. Conclusion: Analysis of the data suggested that, across the themes, there was some lack of information about bullying and cyberbullying. This limitation could affect the subsequent development, dissemination and sustainability of school anti-bullying policies, which have implications for the translation of research to inform better student outcomes.  相似文献

This study addressed (1) whether there were unique profiles of student self-reported reasons for attending school among 10th graders, (2) whether these profiles were differentially associated with late high-school dropout, and (3) whether parent characteristics differed across profiles. Using data from the Educational Longitudinal Study of 2002 (N = 15,362), five latent classes were found. The first class (49%) reported intrinsic, identified/introjected, and external motivations for attending school. The second class (32%) attended for identified/introjected and external reasons, while the third class (11%) reported intrinsic and identified/introjected reasons. The final two classes reported only identified/introjected (5%) or external (4%) motivations. Individuals in the identified/introjected and external classes were at greatest risk of dropping out between 10th and 12th grade. A host of parenting characteristics differed across class, with students in the intrinsic-identified/introjected-external class displaying the most favorable pattern of results. Implications for dropout prevention and academic promotion programs are discussed.  相似文献

Syntactic complexity has been recognized as an important construct in writing research, and for the past five decades, many syntactic complexity measures (SCMs) have been examined in numerous studies. This systematic review is the first study of its kind to synthesize 36 studies spanning from 1970 to 2019 by identifying and cataloging all SCMs examined during this period. An analysis was performed on how the use of SCMs varied by genre, grade level, students’ writing ability, and writing quality. Five online databases (Academic Search Premier, ERIC, PsycINFO, Psychology and Behavioral Sciences, and PsycARTICLES) were searched. A total of 48 SCMs were grouped into six categories: T-units and sentences, clauses, phrases, words, combined measures, and other measures. Most studies examined three common SCMs: mean T-unit length, mean number of words per clause, and mean number of clauses per T-unit. The argumentative genre had the highest values for T-unit length and mean number of clauses per T-unit, which could indicate greater sentence complexity. Higher-grade-level students generally construct sentences that are syntactically complex, but comparison between studies was difficult because different studies investigated different SCMs. Although students with higher writing abilities generally construct sentences that are syntactically more complex compared to students with lower writing abilities, the findings are not conclusive, as only a few studies examined this relationship. A similarly inconclusive relationship was found between syntactic complexity and writing quality because only a few studies examined this relationship. More research is needed to examine the relationship between SCMs, writing quality, and genre.

Although numerous universities offer graduate students opportunities to develop their teaching, few studies probe the credit-bearing graduate course in college teaching. A survey of 105 instructors of graduate pedagogy courses in the US and Canada explored their preparation, professional appointments, students, and assignments. Results showed diverse institutional units offer college pedagogy courses, which are taught by instructors with substantial preparation, most frequently to multidisciplinary groups from diverse majors. Many instructors assign teaching statements, though specifics differ. Comparison to the authors' earlier case study reveals an emerging, recognizable, and international course type that coheres in structure, timing, and at least one key assignment. The ubiquity of college pedagogy courses recommends substantial institutional investment, scholarly analysis, and professorial discussion to align them with the contemporary goals and standards of graduate education.  相似文献

Publishers commonly use Article Processing Charges (APCs) to fund open access publications, and some libraries and institutions help local authors pay these costs. However, this strategy is expensive and can usually only address one article at a time. A number of relatively new publishing initiatives rely on a crowdfunding model and allow many libraries to share the cost of open access, often at a fraction of the cost of APCs. This article highlights several alternative publishing projects to help librarians think further about how library funds could be used to support open access.  相似文献

ABSTRACT

Samples of conserved archaeological wood of different ages, origins, and conservation histories were aged in a climate chamber for seven months, while the humidity alternated between 30% RH for 12 hours and 80% RH for 12 hours at a constant temperature of 30°C. Photographs were taken once every hour, which enabled the creation of a time-lapse movie. Some samples degraded visibly, whereas others were unaffected. Most of the samples were robust and would be able to survive well even in a very poor museum climate. Among the sensitive samples, three types of degradation were identified, namely disintegration, pyrite oxidation, and efflorescence of white crystals. Disintegration was ascribed to dimensional changes caused by the RH alternations in very fragile wood. The white efflorescence was interpreted as the recrystallization of an alum-associated substance, possibly mercallite (KHSO4). The pyrite oxidation was observed as the efflorescence of a thick yellow, grey, and green powder. Characterization of selected samples was performed using X-ray fluorescence spectrometry, X-ray diffraction spectrometry, scanning electron microscopy with energy dispersive X-ray spectroscopy, inductively coupled plasma – optical emission spectroscopy, Fourier transform infrared spectroscopy, ionic conductivity – liquid chromatography, and pyrolysis-gas chromatography-mass spectrometry with in situ silylation using hexamethyldisilazane.  相似文献

ABSTRACT

This study sought to investigate the opioid epidemic impact on North Carolina public libraries. Libraries in half of all 100 counties were chosen through a random, geographically systematic process, and structured interviews were completed with library directors. Twenty directors were interviewed, representing 28 counties. All reported their communities were affected; nine reported direct impacts on library function. Fifteen directors felt libraries should be involved in response; some felt Narcan administration was beyond library purview. Two libraries reported having Narcan available; five reported providing staff training. Given librarians’ willingness to respond, it is time to provide necessary support for those efforts.  相似文献

Acute ingestion of ketone salts induces nutritional ketosis by elevating β-hydroxybutyrate (βHB), but few studies have examined the metabolic effects of ingestion prior to exercise. Nineteen trained cyclists (12 male, 7 female) undertook graded exercise (8 min each at ~30%, 40%, 50%, 60%, 70%, and 80% VO2peak) on a cycle ergometer on two occasions separated by either 7 or 14 days. Trials included ingestion of boluses of either (i) plain water (3.8?mL?kg?body mass?1) (CON) or (ii) βHB salts (0.38?g?kg?body mass?1) in plain water (3.8?mL?kg body mass?1) (KET), at both 60 min and 15 min prior to exercise. During KET, plasma [βHB] increased to 0.33?±?0.16?mM prior to exercise and 0.44?±?0.15?mM at the end of exercise (both p?.05). Plasma glucose was 0.44?±?0.27?mM lower (p?.01) 30?min after ingestion of KET and remained ~0.2?mM lower throughout exercise compared to CON (p?.001). Respiratory exchange ratio (RER) was higher during KET compared to CON (p?.001) and 0.03–0.04 higher from 30%VO2peak to 60%VO2peak (all p?.05). No differences in plasma lactate, rate of perceived exertion, or gross or delta efficiency were observed between trials. Gastrointestinal symptoms were reported in 13 out of 19 participants during KET. Acute ingestion of βHB salts induces nutritional ketosis and alters the metabolic response to exercise in trained cyclists. Elevated RER during KET may be indicative of increased ketone body oxidation during exercise, but at the plasma βHB concentrations achieved, ingestion of βHB salts does not affect lactate appearance, perceived exertion, or muscular efficiency.  相似文献
