Abstract

The aim of our research was to study the relationships between performance variables in a support backward swing (SBS), which was used as a progressive step in the learning procedure for a 1#fr1/4> straddle‐piked front somersault and the swing prior to a 1#fr1/4> straddle‐piked front somersault from support to bent arm support on the parallel bars (5/4S). Mitja Petkov?ek, parallel bars gold medallist at the 2000 EC in Bremen, performed these elements. Kinematic analysis involved CMAS software (Praha, 1993), and the Suskana body segment model that has 17 points and 15 segments. Kinetic variables were estimated using 2D IMGIM software, which has 8 points and 6 segments (Colja and ?uk, 1994). The results indicated that some kinematic aspects of the two types of swings were similar but there were important differences in kinetic aspects of the motion. During the swing for the 5/4S, force and torque were higher than in the SBS.  相似文献   

Effects of Hedonic and Eudaimonic Motivations on Film Enjoyment Through Moral Disengagement     

Mina Tsay-Vogel  K. Maja Krakowiak 《Communication Research Reports》2016,33(1):54-60

In light of literature documenting differences in viewers’ entertainment preferences, this study (N = 168) examined how motivations for film consumption based on pleasure (hedonism) and meaning (eudaimonia) are associated with moral disengagement and enjoyment of content featuring a morally ambiguous character. Findings indicate that whereas hedonic motivation positively influenced moral disengagement, eudaimonic motivation had the reverse effect. Furthermore, eudaimonic motivation had a direct positive influence on enjoyment, and the relationship between hedonic motivation and enjoyment was mediated by moral disengagement. Implications for the role of morality as it relates to individual preferences for media consumption and enjoyment are discussed.  相似文献   

Biotechnology learning in Slovenian upper-secondary education: gaining knowledge and forming attitudes     

Maja Paš  Janez Vogrinc  Peter Raspor  Nada Udovč Kneževič  Jožica Čehovin Zajc 《Research in Science & Technological Education》2019,37(1):110-125

Purpose: One area of science that will increasingly influence our society is biotechnology. An increasing number of modern biotechnological applications have provoked consideration of the ethical and social issues; therefore, it is important that the public is well-informed about them. Formal education in upper-secondary schools should help students to become biotechnologically literate citizens. There is little published research data on Slovenian high-school students’ knowledge about and attitudes towards biotechnology, as well a lack of curriculum evaluation data.

Methodology: This study combines two research approaches. The first part is content analysis of current upper-secondary education programmes in Slovenia, in which all curricula were reviewed about 15 selected biotechnological topics. The second part of the research focused on assessing students’ knowledge of traditional and modern biotechnology and exploring their attitudes towards modern biotechnological methods and their products. The sample included 1163 students aged 17–18 from three different types of schools located in 12 different regions of Slovenia. A questionnaire to measure knowledge and attitudes was designed.

Results: The research results revealed that selected biotechnological concepts appeared most frequently in the curri- cula of bio-technical gymnasia. These students also showed the 30 highest level of knowledge and the most positive attitudes. Furthermore, a clear correlation between students’ knowledge of and attitudes towards modern biotechnology was found. On the other hand, no significant differences in attitudes to the state- ments, which dealt with ethics, were found among the students 35 involved in the research.

Conclusion: Biotechnology teaching in upper-secondary education in Slovenia is obviously very diverse and dependent on the programme.  相似文献   

The use of ICT devices by older people with a special focus on their type and respondents’ age: A Czech case study     

Ivana Šimonová  Petra Poulová  Pavel Pražák 《Educational gerontology》2017,43(12):641-649

The recent demographic trends show a rapid increase of aging population, especially in developed countries. Therefore, there is an urgent need to look for the opportunities of maintaining the quality of life of this aging population. One of the solutions seems to be the use of information and communication technology (ICT) devices, which can promote autonomy of older people by facilitating the execution of many routine activities such as shopping or communication. The purpose of this study is to explore the use of ICT devices among older people in the Czech Republic with respect to their type and respondents’ age. The methods include a questionnaire survey, as well as statistical processing of data collection. The results indicate that present seniors are becoming more digitally literate, especially in the use of mobile phones. However, the use of the technological devices then dramatically drops at the age of 75 years. In addition, the results indicate that future research should focus on the use of mobile phones, respectively smartphones, and its effectiveness on the improvement of quality of life of older generation groups.  相似文献

The effect of body composition and BMI on 25(OH)D response in vitamin D-supplemented athletes     

Evan P. Cassity  Maja Redzic  Cassidy R. Teager 《European Journal of Sport Science》2016,16(7):773-779

Fat mass is inversely associated with vitamin D status, and athletes with the most adipose tissue may have the greatest risk for insufficient (25(OH)D 20–32?ng?mL^?1) or deficient (25(OH)D??1) status. The effects of fat and lean mass on 25(OH)D change in response to vitamin D supplementation have yet to be elucidated in athletes. In addition, vitamin D has a known role in bone health yet a link between short-term changes in 25(OH)D and bone turnover in indoor athletes have not yet been described. Thirty-two collegiate swimmers and divers (19 male, 13 female; 19 (1) years) participated in a 6-month randomized controlled trial and consumed either 4000?IU?d^?1 of vitamin D₃ (n?=?19) or placebo (PLA; n?=?13). Anthropometry and blood collection of 25(OH)D, bone-specific alkaline phosphatase (B-ALP) and N-terminal telopeptide (NTx) occurred at three time points. Dual-energy X-ray absorptiometry measured body composition analysis at baseline and endpoint. In the vitamin D group, BMI was negatively correlated with 6-month 25(OH)D change (R?=??0.496; P?=?.03) and a stronger predictor of 25(OH)D change (P?=?.04) than ultraviolet B exposure and fat mass change. Athletes in the high bone turnover group showed significantly greater losses of 25(OH)D over 6-months compared to athletes in the low bone turnover group (P?=?.03). These results suggest athletes within the normal BMI category experience a diminished response to 4000?IU?d^?1 of vitamin D₃ supplementation, and periods of high bone turnover may be an additional risk factor for developing compromised vitamin D status in athletes.  相似文献   

Burnout among university faculty: the central role of work–family conflict     

Kateřina Zábrodská  Jiří Mudrák  Iva Šolcová  Petr Květon  Marek Blatný  Kateřina Machovcová 《教育心理学》2018,38(6):800-819

This study examined both direct and indirect associations of faculty burnout with psychosocial work environments, using the job resources-demands framework. A sample of 2,229 faculty members (57.1% male) throughout public universities in the Czech Republic completed a questionnaire comprising measures of burnout and psychosocial work environment characteristics from the Copenhagen Psychosocial Questionnaire II. We formulated a structural model that hypothesised a positive effect of job demands (quantitative demands, work-family conflict (WFC), job insecurity) and a negative effect of job resources (influence, social community, role clarity) on burnout. Results showed that the strongest predictor of burnout was WFC, which had a direct positive effect on burnout and mediated the positive effect of quantitative demands on burnout. Further, a small direct negative effect of age and an indirect positive effect of involvement in research grants and administrative paperwork on burnout were observed. The findings indicate that university management can most effectively address burnout in academic staff not only by implementing policies that reduce WFC, workload and administrative paperwork, but also by providing more job resources to younger faculty and faculty involved in grant-based projects.  相似文献   

Attitudes of Anatomy Students toward Commemorations for Body Donors: A Multicultural Perspective     

Joyce El-Haddad  Tania Prvan  Goran Štrkalj 《Anatomical sciences education》2021,14(1):89-98

Many medical schools practice commemorative ceremonies to honor body donors. Attitudes of medical education stakeholders toward these ceremonies have not yet been fully investigated. The aim of this study was to explore anatomy students' attitudes toward commemorations at a multicultural institution which has not introduced these ceremonies yet. A survey was carried out on different groups of anatomy students that were exposed and not yet exposed to human remains. The survey was used to record basic demographic data from the respondents, ask if they would support the establishment of an anatomy commemoration and in which format. A total of 756 anatomy students participated in the survey (response rate 69.8%). The majority (76.3%) were in favor of introducing a commemoration for donors. The associations of students' gender, attitude toward body donation, and level of exposure to human remains with attitudes toward commemoration for donors were identified (P < 0.05), whereas ethnicity and religion seemed to have no influence on attitudes (P > 0.05). Most students believed that anatomy staff and students should organize the commemoration. There was a preference for the commemoration to be secular with revealed identities of donors, and not recorded for social media. The support for the establishment of commemorations transcended cultural and religious differences and confirmed students' respectful attitude toward donors. Anatomy commemorations seem to have potential not only to engage students with one another, and donor families, but also to pave the way for students to become life-long ethical and empathetic learners and practitioners.  相似文献
