Sporting shades of green: a comparative analysis of sponsored national mythmaking in Irish rugby and soccer     

Neil O’Boyle  Colm Kearns 《Sport in Society》2017,20(7):969-986

This paper derives from an ongoing study of how modern sports contribute to the (re)definition of national identities in the context of increasing marketization and mediatization of sport at different levels. In this paper, we examine the symbolic tensions surrounding Three Ireland’s concurrent sponsorship of the Irish international football and rugby union teams via an analysis of two television commercials commissioned by the sponsor. We suggest that although different signifiers of Irish identity are employed in the football and rugby commercials examined – and that each ostensibly represents a different ‘version’ of Irish identity – both campaigns draw largely from a common fund of cultural authenticity. Our analysis suggests that Three Ireland has constructed broad texts that comfortably accommodate differing signifiers of Irish identity and that permit the sponsor to trade in limited and controllable degrees of cultural difference. More broadly, our paper demonstrates how national identity can function as a ‘multi-directional symbol’.  相似文献   

The effect of badminton-specific exercise on badminton short-serve performance in competition and practice climates     

Michael J. Duncan  Cheryl K.Y. Chan  Neil D. Clarke  Martin Cox  Mike Smith 《European Journal of Sport Science》2017,17(2):119-126

This study examined the effects of changes in physiological and psychological arousal on badminton short-serve performance in competitive and practice climates. Twenty competitive badminton players (10 males and 10 females) volunteered to participate in the study following ethics approval. After familiarisation, badminton short-serve performance was measured at rest, mid-way through and at the end of a badminton-specific exercise protocol in two conditions; competition vs. practice. Ratings of cognitive and somatic anxiety were assessed at three time points prior to badminton short-serve performance using the Mental Readiness Form 3. Heart rate and rating of perceived exertion (RPE) were assessed during the exercise protocol. Results indicated that better short-serve performance was evident in practice compared to competition (P?=?.034). RPE values were significantly higher in the competition condition compared to practice (P?=?.007). Cognitive anxiety intensity was significantly lower post-exercise in the practice condition compared to competition (P?=?.001). Cognitive anxiety direction showed greater debilitation post-exercise in the competition condition compared to practice (P?=?.01). Somatic anxiety intensity increased from pre-, to mid- to post-exercise (P?=?.001) irrespective of condition. This study suggests that badminton serve performance is negatively affected when physiological arousal, via badminton-specific exercise, and cognitive anxiety, via perceived competition, are high.  相似文献   

Alterations to the orientation of the ground reaction force vector affect sprint acceleration performance in team sports athletes     

Neil E. Bezodis  Jamie S. North  Jane L. Razavet 《Journal of sports sciences》2017,35(18):1817-1824

A more horizontally oriented ground reaction force vector is related to higher levels of sprint acceleration performance across a range of athletes. However, the effects of acute experimental alterations to the force vector orientation within athletes are unknown. Fifteen male team sports athletes completed maximal effort 10-m accelerations in three conditions following different verbal instructions intended to manipulate the force vector orientation. Ground reaction forces (GRFs) were collected from the step nearest 5-m and stance leg kinematics at touchdown were also analysed to understand specific kinematic features of touchdown technique which may influence the consequent force vector orientation. Magnitude-based inferences were used to compare findings between conditions. There was a likely more horizontally oriented ground reaction force vector and a likely lower peak vertical force in the control condition compared with the experimental conditions. 10-m sprint time was very likely quickest in the control condition which confirmed the importance of force vector orientation for acceleration performance on a within-athlete basis. The stance leg kinematics revealed that a more horizontally oriented force vector during stance was preceded at touchdown by a likely more dorsiflexed ankle, a likely more flexed knee, and a possibly or likely greater hip extension velocity.  相似文献   

Effects of movement velocity and training frequency of resistance exercise on functional performance in older adults: a randomised controlled trial     

Darren L. Richardson  Michael J. Duncan  Alfonso Jimenez  Paul M. Juris  Neil D. Clarke 《European Journal of Sport Science》2019,19(2):234-246

Objectives: To investigate the effects that high-velocity, low-load (HVLL) and low-velocity, high-load (LVHL) resistance exercise, performed once or twice-weekly, have on indices of functional performance (primary outcome), maximal strength, and body composition (secondary outcomes) in older adults.

Methods: In a randomised, controlled, multi-armed, parallel design, 54 moderately-highly active, but resistance exercise naïve older adults (aged 60–79 years), attended baseline and post-10-week intervention assessment sessions. Physical and functional assessments were completed, and predicted one-repetition maximums (1-RM) were obtained for eight exercises. Participants were then randomised into one of five conditions: HVLL once-weekly (HVLL1: n?=?11) or twice-weekly (HVLL2: n?=?11), LVHL once-weekly (LVHL1: n?=?10) or twice-weekly (LVHL2: n?=?11), no-exercise control condition (CON: n?=?11). The HVLL conditions completed 3 sets of 14 repetitions at 40% 1-RM and the LVHL conditions, 3 sets of 7 repetitions at 80% 1-RM. In total, 50 participants completed all testing and were included in analyses.

Results: Only LVHL2 improved 30-sec chair stand performance (p?=?.035; g?=?0.89), arm curls (p?=?.011; g?=?1.65) and grip-strength (p?=?.015; g?=?0.34) compared to CON. LVHL2 improved maximal strength compared to CON for 7/8 exercises (p?p?Conclusion: Possibly due to the lower intensity nature of the HVLL conditions, LVHL, twice-weekly was most beneficial for improving functional performance and strength in moderately-highly active older adults. Therefore, we recommend that exercise professionals ensure resistance exercise sessions have sufficient intensity of effort and volume, in order to maximise functional performance and strength gains in older adults.  相似文献   

Perceptual influence of psychoeducational reports     

Neil H. Schwartz  William K. Wilkinson 《Psychology in the schools》1987,24(2):127-135

In the present study, teachers read fictitious psychoeducational reports that interpretively were consistent, inconsistent, or absent with respect to a child's diagnostic label. On a perceptual expectation questionnaire, teachers indicated both their perceptions of the child and their confidence in these perceptions, after reading a cumulative folder and again after reading a psychoeducational report. Although the reports differed by just one or two interpretive statements, results revealed that teacher perceptions of child characteristics changed in an adaptive direction for the school performance clusters of general adjustment, academic skill, and learning approach, while report interpretation negatively influenced ratings for intellectual capacity. Further, the type of diagnostic label provided in the cumulative folder was an important variable in determining the perceptual effect of the report's interpretation, since different patterns of teacher perception and their confidence in these perceptions were observed for LD, BD, or EMH labels.  相似文献   

The Citation Cloud of a biomedical article: a free,public, web-based tool enabling citation analysis     

Neil R. Smalheiser  Jodi Schneider  Vetle I. Torvik  Dean P. Fragnito  Eric E. Tirk 《Journal of the Medical Library Association》2022,110(1):103

Background:An article''s citations are useful for finding related articles that may not be readily found by keyword searches or textual similarity. Citation analysis is also important for analyzing scientific innovation and the structure of the biomedical literature. We wanted to facilitate citation analysis for the broad community by providing a user-friendly interface for accessing and analyzing citation data for biomedical articles.Case Presentation:We seeded the Citation Cloud dataset with over 465 million open access citations culled from six different sources: PubMed Central, Microsoft Academic Graph, ArnetMiner, Semantic Scholar, Open Citations, and the NIH iCite dataset. We implemented a free, public extension to PubMed that allows any user to visualize and analyze the entire citation cloud around any paper of interest A: the set of articles cited by A, those which cite A, those which are co-cited with A, and those which are bibliographically coupled to A.Conclusions:Citation Cloud greatly enables the study of citations by the scientific community, including relatively advanced analyses (co-citations and bibliographic coupling) that cannot be undertaken using other available tools. The tool can be accessed by running any PubMed query on the Anne O''Tate value-added search interface and clicking on the Citations button next to any retrieved article.  相似文献   

“Participation” in the internationalized higher education classroom: An academic staff perspective     

Neil Murray  Troy McConachy 《Journal of International and Intercultural Communication》2018,11(3):254-270

For universities seeking to promote internationalization, the development of an understanding and appreciation of cultural diversity among staff and students is a priority. Cultural and linguistic diversification of the student body can, however, present academic staff with challenges in the areas of curriculum, teaching methods and assessment. In this study, we take up the culturally variable notion of “participation” as a constituent of learning and draw on data derived from focus group interviews to probe the participation-related challenges reported by academic staff in a UK university. Finally, we consider the implications of our findings for strategic interventions aimed at academic staff.  相似文献   

Using Weighted Sum Scores to Close the Gap Between DIF Practice and Theory     

Hongwen Guo  Neil J. Dorans 《Journal of Educational Measurement》2020,57(4):484-510

We make a distinction between the operational practice of using an observed score to assess differential item functioning (DIF) and the concept of departure from measurement invariance (DMI) that conditions on a latent variable. DMI and DIF indices of effect sizes, based on the Mantel-Haenszel test of common odds ratio, converge under restricted conditions if a simple sum score is used as the matching or conditioning variable in a DIF analysis. Based on theoretical results, we demonstrate analytically that matching on a weighted sum score can significantly reduce the difference between DIF and DMI measures over what can be achieved with a simple sum score. We also examine the utility of binning methods that could facilitate potential operational use of DIF with weighted sum scores. A real data application was included to show this feasibility.  相似文献   

Teaching science to students with developmental disabilities using the Early Science curriculum     

Magdalena M. Apanasionok  Julie Neil  Richard C. Watkins  Corinna F. Grindle  Richard P. Hastings 《Support for Learning》2020,35(4):493-505

There is a large science attainment gap between students with and without special educational needs, and many students with developmental disabilities (DD) struggle to access the mainstream science programmes of study. The purpose of the present project was to pilot the use of the Early Science (ES) curriculum over a six week period with nine students with moderate to severe DD in a special education setting in the UK. Staff members indicated positive experiences of using the curriculum, especially the use of the structured teaching methodology as a helpful tool. Evaluation data suggested that all nine pupils improved their science knowledge over the course of the intervention. Some suggestions are made to improve the delivery of the ES curriculum in UK special education settings, and the need for larger scale evaluation research.  相似文献
