A three-dimensional examination of the planar nature of the golf swing     

Coleman SG  Rankin AJ 《Journal of sports sciences》2005,23(3):227-234

Previous planar models of the downswing in golf have suggested that upper limb segments (left shoulder girdle and left arm) move in a consistent fixed plane and that the clubhead also moves only in this plane. This study sought to examine these assumptions. Three-dimensional kinematic analysis of seven right-handed golfers of various abilities (handicap 0- 15) was used to define a plane (named the left-arm plane) containing the 7th cervical vertebra, left shoulder and left wrist. We found that the angles of this plane to the reference horizontal z axis and target line axis (parallel to the reference x axis) were not consistent. The angle to the horizontal z axis varied from a mean of 133 degrees (s = 1 degrees) at the start of the downswing to 102 degrees (s = 4 degrees) at impact, suggesting a "steepening" of the left-arm plane. The angle of the plane to the target line changed from - 9 degrees (s = 16 degrees) to 5 degrees (s = 15 degrees) during the same period, showing anticlockwise (from above) rotation, although there was large inter-individual variation. The distance of the clubhead from the left-arm plane was 0.019 m (s = 0.280 m) at the start at the downswing and 0.291 m (s = 0.077 m) at impact, showing that the clubhead did not lie in the same plane as the body segments. We conclude that the left arm and shoulder girdle do not move in a consistent plane throughout the downswing, and that the clubhead does not move in this plane. Previous models of the downswing in golf may therefore be incorrect, and more complex (but realistic) simulations should be performed.  相似文献   

Team-referent attributions among sport performers     

Greenlees I  Lane A  Thelwell R  Holder T  Hobson G 《Research quarterly for exercise and sport》2005,76(4):477-487

The aim of this study was to develop and validate a team-referent attribution scale. Conducted over three studies, Study 1 modified items from McAuley, Duncan, and Russell's (1992) Causal Dimension Scale II by rewording items to reflect team attributions and adding one item per factor. This led to the development of a 16-item scale (Causal Dimension Scale-T, CDS-T). Study 2 tested competing models of attribution theory among a sample of 433 team sport players. Confirmatory factor analysis indicated strongest support for a four-factor model (robust comparative fit index = .961; root mean squared error of approximation = .054). Study 3 tested the predictive validity of the scale among a sample of 201 team players. Results indicated that winners reported more internal and stable attributions than losers. Further, performances perceived as successful were associated with stable attributions. The results of the study, therefore, suggest that the CDS-T provides a valid measure of team-referent attributions in sport.  相似文献   

Accelerometry-based feedback--can it improve movement consistency and performance in rowing?     

Anderson R  Harrison A  Lyons GM 《Sports biomechanics / International Society of Biomechanics in Sports》2005,4(2):179-195

The training and competition regimen of elite athletes demands rapid feedback about their performance. The aim of this study was to determine if real-time visual ipsative (comparison with oneself) feedback of instantaneous kinematic consistency improves overall kinematic consistency in rowing. Accelerometry-based data, representing the upper and lower body kinematics, were determined for 13 experienced rowers. Kinematic consistency data -- represented by percentage time outside the acceptable performance bandwidth, performance consistency -- represented by power-stroke dispersion, and several performance indicators were acquired for all the rowers for three 2000 m time trials on a RowPerfect ergometer with three different visual feedback interventions: no feedback, detailed feedback, and summary feedback. Results indicated significantly increased performance consistency for detailed feedback than for both no feedback (p < 0.01) and summary feedback (p < 0.05). No significant difference between summary feedback and no feedback was found (p = 0.173). We deemed feedback of detailed information to enhance kinematic consistency significantly more than both no feedback (p < 0.01) and summary feedback (p < 0.01) interventions, although summary feedback was shown to enhance kinematic consistency more than no feedback (p < 0.01). No improvements were found for performance-related parameters.  相似文献   

Relational Maintenance Behavior and Shared TV Viewing as Mediators of the Association Between Romanticism and Romantic Relationship Quality     

Andrew M. Ledbetter 《Communication Studies》2017,68(1):95-114

Nearly a century of research has demonstrated a positive association between romanticism—a relationship-type schema that emphasizes idealistic and positive experiences in romantic relationships—and quality of romantic relationships. This investigation examined whether relational maintenance behavior and shared TV viewing mediate that association. The sample contained 202 participants, including college students and older adults. Results demonstrated that relational maintenance behavior mediated the association between romanticism and relationship quality, but shared TV viewing did not. Nevertheless, shared TV viewing independently and positively predicted variance in relationship quality. These results both clarify the mechanism by which romanticism may operate and support shared media use as a maintenance behavior that may be meaningful in close relationships.  相似文献

Measuring Trust in the Press in a Changing Media Environment     

Andrew Daniller  Douglas Allen  Ashley Tallevi 《Communication methods and measures》2017,11(1):76-85

The only long term trend data on trust in the American press comes from the General Social Survey (GSS). The erosion of trust in the press as measured by the GSS indicator is indisputable, but its implications for the functioning of American democracy depend on what, precisely, is being measured. In this study we use an experimental design embedded in a representative national probability sample to shed light on what people are thinking of when they say they trust or distrust the American press. Are they thinking about the sources they themselves use for news? The sources that are most popular with the population at large? An average of all possible media sources? We find that individuals express much greater trust in the press when they are asked to consider specific news sources than when they are asked to evaluate a generic news media. Our results suggest that an accessibility bias combined with the proliferation of news sources in recent years may lead individuals to think of distrusted sources when asked to answer generic media trust questions. We therefore argue that different measurement strategies are needed to successfully address trust in the press in the current news environment.  相似文献   

A ripple that ruffled feathers: an appreciation of 30 years of Michael Rosen's poetry for children     

Andrew Lambirth 《Changing English: An International Journal of English Teaching》2006,13(1):45-54

This article is a personal appreciation and analysis of the poetry of Michael Rosen. Drawing on his work over 30 years, the article argues that at the heart of Rosen's work is a passionate belief in aesthetic, political and personal emancipation. Included in the pleasure that his work evokes, is a challenge to a number of preconceived notions about childhood, literature, relationships and living. He questions how children see adults and how adults see children, and with a breathtaking honesty, the whole world of children's literature and its impact on conceptualisations of children is put in the foreground. The article examines Rosen's use of autobiography in his poems, his groundbreaking use of free verse in children's literature and his relation to modernity.  相似文献   

General Issues about Assessment of Competence     

Paul Hager  Andrew Gonczi  James Athanasou 《Assessment & Evaluation in Higher Education》1994,19(1):3-16

In simple terms, competency‐based assessment is the assessment of a person's competence against prescribed standards of performance. Thus, if an occupation has established a set of, say, entry‐level competency standards, then these prescribe the standards of performance required of all new entrants to that occupation. Competency‐based assessment is the process determining whether a candidate meets the prescribed standards of performance, i.e. whether they demonstrate competence.

It is probably a truism that there is no such thing as a process of assessment that is without its critics. Whatever efforts are made to improve an instance of assessment, someone is bound to be unhappy with the process. Competency‐based assessment is therefore at a particular disadvantage since it is both new and unfamiliar to many people. This has meant that competency‐based assessment has aroused numerous and varied worries and objections from many quarters. In the process of researching assessment methods of professions in Australia, as the prelude to writing a guide on competency‐based assessment (Gonczi et al., 1993) the authors identified a number of worries and objections. Competency‐based assessment: (a) only assesses what is trivial or superficial; (b) is inherently unreliable in that it involves inference; (c) is inherently invalid, (d) represents a departure from traditional proven methods of assessment; (e) neglects the importance of knowledge; (f) focuses on outcomes to the neglect of processes; (g) relies on professional judgement, and hence is too subjective; (h) vainly tries to assess attitudes. This paper discusses each of these worries and objections and shows that none of them is decisive. While each of them points to an important issue about competency‐based assessment, the discussion will show that in each case a well‐designed competency‐based assessment system can overcome the worry or objection.  相似文献
