A person-centered approach to achievement goal orientations in competitive tennis players: Associations with motivation and mental toughness     

Richard Gregory Cowden  Nicolas Mascret  Timothy Ryan Duckett 《运动与健康科学(英文)》2021,10(1):73-81

Background:Research on achievement goal orientations in sport has typically relied on the use of variable-centered approaches that tend to overlook population heterogeneity.In this study,we used a person-centered approach to identify subgroups of competitive tennis players according to unique combinations of achievement goal orientations and tested for subgroup differences in motivation and mental toughness.Methods:A sample of 323 competitive tennis athletes(69.35%male)between 15 and 25 years of age(17.60±2.40 years,mean±SD)completed the 3×2 Achievement Goal Questionnaire for Sport,Sport Motivation Scale Ⅱ,and Mental Toughness Index.Latent profile analysis was used to identify unique combinations of achievement goal orientations.Comparisons between latent subgroups on autonomous motivation,controlled motivation,and mental toughness were performed using analysis of variance.Results:Latent profile analysis supported 3 distinct patterns of achievement goal profiles that were primarily distinguishable based on valence of competence(i.e.,approach vs.avoidance).Analyses of variance indicated that athletes who were classified into subgroups that endorsed approach types of goals(regardless of the types of avoidance goals they endorsed)reported higher levels of autonomous motivation and mental toughness.Conclusion:Results indicated that athletes tend to pursue a number of achievement goals collectively rather than in isolation.Although approach goals are more commonly linked to adaptive psychological functioning and positive outcomes,avoidance goals may also be associated with desirable psychological characteristics if they are pursued in conjunction with approach types of achievement goals.  相似文献

Cultural Differences in Garnering Social Capital on Facebook: French People Prefer Close Ties and Americans Prefer Distant Ties     

Genavee Brown  Nicolas Michinov 《Journal of Intercultural Communication Research》2017,46(6):579-593

The link between social capital (SC) and Facebook has been widely studied in the U.S., and less is known about how students from different cultures use the site to garner SC. We measured network composition, communication on Facebook, and SC via questionnaires in France and the U.S. We found that American students have a greater proportion of distant to close ties in their networks and higher levels of bridging SC than French, the latter preferring bonding SC. A stronger relationship between SC and communication via Facebook was observed in the U.S. These findings are explained by cultural differences in relatedness.  相似文献   

Questioning the no-touch discourse in physical education from a children's rights perspective     

Marie Öhman  Ann Quennerstedt 《Sport, Education and Society》2017,22(3):305-320

In this paper we question the rationality of ‘no-touch policies’ and offer an alternative approach to the matter of physical contact between teachers and students in the context of physical education (PE) in schools. Earlier research has drawn attention to how a discourse of child protection is starting to affect how physical contact is viewed in PE practice. The avoidance of intergenerational touch is increasingly justified by referring to the children's rights agenda. Here, arguments for ‘no-touching’ are linked to children's right to be protected from harm. In the paper we explore a children's rights-based viewpoint that supports the use of and need for physical contact in PE teaching by developing theoretical and practice-based arguments. An alternative children's rights perspective, based on rights theorising, is used to formulate the theoretical argument. Interviews with 16 PE teachers about their experiences of physical contact in their pedagogical work form the practice-based arguments. The two arguments provide a way of looking at intergenerational touch in education from the vantage point of children's human right to develop to their full potential, which can support a need for physical touch in pedagogical situations.  相似文献   

Validity and Reliability of Three Self-Report Instruments for Assessing Attainment of Physical Activity Guidelines in University Students     

Joseph J. Murphy  Marie H. Murphy  Ciaran MacDonncha  Niamh Murphy  Alan M. Nevill  Catherine B. Woods 《Measurement in physical education and exercise science》2017,21(3):134-141

The purpose of this study was to compare the validity and reliability of three short physical activity self-report instruments to determine their potential for use with university student populations. The participants (N = 155; 44.5% male; 22.9 ± 5.13 years) wore an accelerometer for 9 consecutive days and completed a single-item measure, the a brief two item measure and the International Physical Activity Questionnaire—Short Form questionnaires on day 1 and 9. Correlations between self-reported and accelerometer derived moderate-to-vigorous physical activity levels were moderate for the International Physical Activity Questionnaire—Short Form, while poor for the single-item measure and the a brief two item measure. The agreement level was high with the International Physical Activity Questionnaire—Short Form (77.4%) and moderate for both the single-item measure (45.2 %) and a brief two item measure (44.5 %). The intraclass correlations between the two administrations were moderate to strong across all measures (0.52–0.70) in 133 participants. The International Physical Activity Questionnaire—Short Form is the most suitable of these three self-report instruments for use with this population due to higher correlations and levels of agreement with accelerometry.  相似文献   

A scale-based approach to interdisciplinary research and expertise in sports     

Jorge Ibáñez-Gijón  Martinus Buekers  Antoine Morice  Guillaume Rao  Nicolas Mascret  Jérome Laurin 《Journal of sports sciences》2017,35(3):290-301

After more than 20 years since the introduction of ecological and dynamical approaches in sports research, their promising opportunity for interdisciplinary research has not been fulfilled yet. The complexity of the research process and the theoretical and empirical difficulties associated with an integrated ecological-dynamical approach have been the major factors hindering the generalisation of interdisciplinary projects in sports sciences. To facilitate this generalisation, we integrate the major concepts from the ecological and dynamical approaches to study behaviour as a multi-scale process. Our integration gravitates around the distinction between functional (ecological) and execution (organic) scales, and their reciprocal intra- and inter-scale constraints. We propose an (epistemological) scale-based definition of constraints that accounts for the concept of synergies as emergent coordinative structures. To illustrate how we can operationalise the notion of multi-scale synergies we use an interdisciplinary model of locomotor pointing. To conclude, we show the value of this approach for interdisciplinary research in sport sciences, as we discuss two examples of task-specific dimensionality reduction techniques in the context of an ongoing project that aims to unveil the determinants of expertise in basketball free throw shooting. These techniques provide relevant empirical evidence to help bootstrap the challenging modelling efforts required in sport sciences.  相似文献   

Is a single question of the Global Physical Activity Questionnaire (GPAQ) valid for measuring sedentary behaviour in the Chilean population?     

Nicolas Aguilar-Farias  Jaime Leppe Zamora 《Journal of sports sciences》2017,35(16):1652-1657

A study was conducted to assess the validity of the Global Physical Activity Questionnaire (GPAQ) for measuring sedentary behaviour (SB) in the Chilean adult population. About 217 adults (93/124 male/female, 43.8 ± 15.75 years) who were randomly selected during National Health Survey 2009–2010 completed the protocol. The participants wore an ActiGraph GT3X (AG) for 7 consecutive days and then completed the GPAQ (single-item question for measuring time spent sitting in a usual day). Validity was examined using Spearman’s correlation, mean bias and limits of agreement (LoA), with AG (vertical axis <100 counts · min^?1) as the reference standard for estimates of SB in bouts of 1 (AG1), 5 (AG5) and 10 (AG10) min. Agreement between the GPAQ and AG for classifying data into quartiles and tertiles was assessed with kappa method. The GPAQ showed fair correlation with AG1, AG5 and AG10 (range = 0.23–0.26), with large mean biases (range = ?293.9, ?76.12 min · day^?1). Agreement between the GPAQ and AG1, AG5 and AG10 was poor for categorising time spent in SB into tertiles and quartiles. The single question from the GPAQ has shown fair validity for measuring SB and poor ability for correctly classifying individuals into tertiles or quartiles of SB in a Chilean population.  相似文献   

Passing on Political Information between Major Powers: The Key Role of Ambassadors between Byzantium and some of its Neighbours     

Nicolas Drocourt 《Al-Masaq: Islam & the Medieval Mediterranean》2012,24(1):91-112

Ambassadors and embassies were numerous between Byzantium and its Muslim and Western Christian neighbours during the Middle Byzantine Period. This article seeks to demonstrate that these official envoys constituted major players involved in the transfer of political information between the courts considered. Ambassadors were those who travelled the most in the Mediterranean area during our period – at least between 700 and 900. Furthermore, as official envoys acting for sovereigns, they were carefully listened to by those sovereigns when they returned. Information coming from ambassadors is found in various sources and concerned military matters and foreign policy. But we also find precise data on domestic affairs and internal political information. Furthermore, news of usurpations and troubles in Byzantium may have constituted an important part of the information transferred beyond the Empire. Foreign ambassadors witnessed usurpations and palace revolutions. Their testimonies could have nourished the idea of a Byzantine government weakened by political instability and this theme became prominent during the twelfth century in some Western Christian courts.  相似文献
