The study used data from the second wave of the Children's Worlds Survey to explore the relation between children's experiences of bullying victimization (physical and psychological) and their subjective well-being (SWB) across three age groups (8, 10, and 12) and 15 global geographical regions. The sample consists of 47,029 children randomly selected from 15 countries. Data were analyzed using structural equation modeling and multigroup confirmatory factor analysis. The results show appropriate fit structure for the overall model, and that the combined influence of physical and psychological bullying made a significant contribution to SWB across age groups and geographical regions. The findings are interpreted using Cummins's (1995) Homeostasis Theory of SWB. 相似文献

Despite immense resources and a growing interest in education and libraries, library development in Kuwait has been restricted by the problems common to all developing countries. These include an overdose of bureaucracy, lack of trained librarians, and little perception of the library's importance in the educational system. Medical librarianship is virtually a new field. The only medical library of any significance in the country is the Faculty of Medicine Library established in 1974 to serve the newly organized Faculty of Medicine of Kuwait University. In recent years, the Faculty of Medicine Library has gone through several reassessments and many changes. It has expanded its collection, begun computerized searching, and recruited several professional librarians. Now semiautonomous from the university's Libraries Department and housed in a new, modern building, the library has the potential to become the main medical library in the Persian Gulf area. 相似文献

The “gender gap” in the U.S. publication of English language and literature scholarly books has not been fully investigated. In order to investigate gender disparity, we collected, aggregated, and analyzed data on 1633 faculty members who authored or edited 4835 scholarly books at the top 50 U.S. English Ph.D. departments. Despite the fact that more women than men have received Ph.D.s in English since 1987, the top 50 departments are predominantly male, and male faculty members publish more books on a per capita basis. However, who publishes more books in these departments varies: (1) with the department that the faculty member is in (with grater parity in the middle 30 departments); and (2) when the faculty member published their first book, with female faculty who published their first book after 1998 publishing as many books on a per person basis as male faculty. This paper also offers recommendations on how marketing strategies can be used to ameliorate the “gender gap” in this academic field. 相似文献

Swing trajectory and ground reaction forces (GRF) of 30 collegiate baseball batters hitting a pitched ball were compared between a standard bat, a bat with extra weight about its barrel, and a bat with extra weight in its handle. It was hypothesised that when compared to a standard bat, only a handle-weighted bat would produce equivalent bat kinematics. It was also hypothesised that hitters would not produce equivalent GRFs for each weighted bat, but would maintain equivalent timing when compared to a standard bat. Data were collected utilising a 500 Hz motion capture system and 1,000 Hz force plate system. Data between bats were considered equivalent when the 95% confidence interval of the difference was contained entirely within ±5% of the standard bat mean value. The handle-weighted bat had equivalent kinematics, whereas the barrel-weighted bat did not. Both weighted bats had equivalent peak GRF variables. Neither weighted bat maintained equivalence in the timing of bat kinematics and some peak GRFs. The ability to maintain swing kinematics with a handle-weighted bat may have implications for swing training and warm-up. However, altered timings of kinematics and kinetics require further research to understand the implications on returning to a conventionally weighted bat. 相似文献

Controversy continues whether curveballs are stressful for young baseball pitchers. Furthermore, it is unproven whether professional baseball pitchers have fewer kinematic differences between fastballs and off-speed pitches than lower level pitchers. Kinematic and kinetic data were measured for 111 healthy baseball pitchers (26 youth, 21 high school, 20 collegiate, 26 minor league, and 18 major league level) throwing fastballs, curveballs, and change-ups in an indoor biomechanics laboratory with a high-speed, automated digitising system. Differences between pitch types and between competition levels were analysed with repeated measures ANOVA. Shoulder and elbow kinetics were greater in fastballs than in change-ups, while curveball kinetics were not different from the other two types of pitches. Kinematic angles at the instant of ball release varied between pitch types, while kinematic angles at the instant of lead foot contact varied between competition levels. There were no significant interactions between pitch type and competition level, meaning that kinetic and kinematic differences between pitch types did not vary by competition level. Like previous investigations, this study did not support the theory that curveballs are relatively more stressful for young pitchers. Although pitchers desire consistent kinematics, there were differences between pitch types, independent of competition level. 相似文献

The issue raised by the authors in this article question why studio art continues to be ignored as a site and source for research in art education. The necessity of the field to be able to participate within the research community in addressing cultural, social, educational and political concerns is acknowledged. It is argued, however, that the exclusive use of methods of inquiry that align with the conventions of social science research has been done at the expense of fully appreciating the capacity of artistic research undertaken in studio contexts. This tendency is especially prevalent in doctoral research in higher education. Three accounts of dissertation research are given that incorporate studio activity as a central agency of inquiry in conceptualising and theorising issues. Each highlights the capacity of art practice to reveal insights that are a consequence of what the researcher did in the studio setting as issues, ideas and interpretive stances emerged, and problems were re‐conceptualised. What is different in these accounts from more mainstream approaches to research is the readiness to accept that constructing new knowledge is a creative and critical process. 相似文献
