The aim of the study was to determine if sex differences exist in the key elbow and wrist joint injury risk factors during different cartwheel (CW) and round-off (RO) techniques performed by young male and female artistic gymnasts. Sixteen active young gymnasts (8 males and 8 females) performed 30 successful trials of CW and RO with three different hand positions (parallel (10), T-shape (10) and reverse (10)). Synchronised kinematic and kinetic data were collected for each trial. Two-way repeated measures ANOVA (3 × 2, technique × sex) and effect-sizes (ES) were used for statistical analysis. In conclusion, female gymnasts exhibited greater normalised peak vertical ground reaction forces (VGRF), elbow and wrist compression forces and elbow internal adduction moments during CW and RO skills compared with male gymnasts. In both sexes, the parallel and reverse techniques increased peak VGRF, elbow and wrist compression forces and the elbow internal adduction moment. Increased elbow flexion resulted in decreased peak VGRF, elbow compression forces and elbow internal adduction moment. Injury risk factors including elbow extension and internal adduction moment with axial compression force suggest that a CW and RO in reverse and parallel techniques can be hazardous especially for young female gymnasts.  相似文献   

Allied healthcare undergraduate education: international students at the clinical interface     

Gareth Morgan 《Journal of Further & Higher Education》2017,41(3):286-300

The global movement of students in higher education is a relatively recent phenomenon, which has gained momentum in the last 30 years. Much research has been focused on the experiences of this population. Relatively little is known about international allied healthcare students who undertake clinical placements as part of their undergraduate course. This study explores students’ perceptions of their clinical experience. The chosen focus group method was prefaced by a pilot study; both were conducted within the allied healthcare school of a university in the UK. Four themes emerged from the study: communication, cultural differences, relationships with professionals and survival strategies. Communication referred to both the interaction with and between the students, their patients and fellow members of the multidisciplinary team. Cultural differences were expressed in the negotiation of differing cultures at the patient interface. A third theme was the students’ relationship with clinical professionals; within this, the relationship with the student’s clinical educator was paramount. Finally, survival strategies represented the advice students wished to impart to future international students to facilitate their clinical placement abroad.  相似文献   

Consistency of Angoff-Based Predictions of Item Performance: Evidence of Technical Quality of Results From the Angoff Standard Setting Method     

Barbara S. Plake  James C. Impara  Patrick M. Irwin 《Journal of Educational Measurement》2000,37(4):347-355

Judgmental standard-setting methods, such as the Angoff(1971) method, use item performance estimates as the basis for determining the minimum passing score (MPS). Therefore, the accuracy, of these item peformance estimates is crucial to the validity of the resulting MPS. Recent researchers (Shepard, 1995; Impara & Plake, 1998; National Research Council. 1999) have called into question the ability of judges to make accurate item performance estimates for target subgroups of candidates, such as minimally competent candidates. The propose of this study was to examine the intra- and inter-rater consistency of item performance estimates from an Angoff standard setting. Results provide evidence that item pelformance estimates were consistent within and across panels within and across years. Factors that might have influenced this high degree of reliability, in the item performance estimates in a standard setting study are discussed.  相似文献   

Total quality management in higher education: Panacea or placebo?   总被引：1，自引：0，他引：1  

Gareth Williams 《Higher Education》1993,25(3):229-237

Total Quality Management is a concept that has permeated the thinking of many higher education managers very quickly within the past five years. It is a product of the market ideologies of the 1980s and the managerialism which accompanied them. Nevertheless, despite the special features of higher education as a set of activities based on the creation and dissemination of knowledge and understanding, the paper argues, largely by reference to the subsequent articles, that the main themes of TQM, continuous quality improvement, consistency of quality, staff (and student) participation, meeting customer needs, coordination, and management procedures which detect poor quality and stimulate good, all have a significant contribution to make to the development of efficient and effective mass higher education systems and institutions, whether or not they are explicitly market oriented.  相似文献   

Infants' Reliance on a Social Criterion for Establishing Word-Object Relations   总被引：3，自引：0，他引：3  

Dare A. Baldwin  Ellen M. Markman  Brigitte Bill  Renee N. Desjardins  Jane M. Irwin  Glynnis Tidball 《Child development》1996,67(6):3135-3153

The language children hear presents them with a multitude of co-occurrences between words and things in the world, and they must repeatedly determine which among these manifold co-occurrences is relevant. Social factors—such as cues regarding the speaker's referential intent—might serve as one guide to whether word-object covariation should be registered. In 2 studies, infants (15–20 months and 18–20 months in Studies 1 and 2, respectively) heard novel labels at a time when they were investigating a single novel object; in one case the label was uttered by a speaker seated within the infant's view and displaying concurrent attention to the novel toy (coupled condition), whereas in the other case the label emanated from a speaker seated out of the infant's view (decoupled condition). In both studies, subsequent comprehension questions indicated that infants of 18–20 months registered a stable link between label and object in the coupled condition, but not in the decoupled condition, despite the fact that covariation between label and object was equivalent in the 2 conditions. Thus, by 18–20 months children are inclined to establish a mapping between word and object only when a speaker displays signs of referring to that object.  相似文献

Convergent genomic signatures of high-altitude adaptation among domestic mammals

Abundant and diverse domestic mammals living on the Tibetan Plateau provide useful materials for investigating adaptive evolution and genetic convergence. Here, we used 327 genomes from horses, sheep, goats, cattle, pigs and dogs living at both high and low altitudes, including 73 genomes generated for this study, to disentangle the genetic mechanisms underlying local adaptation of domestic mammals. Although molecular convergence is comparatively rare at the DNA sequence level, we found convergent signature of positive selection at the gene level, particularly the EPAS1 gene in these Tibetan domestic mammals. We also reported a potential function in response to hypoxia for the gene C10orf67, which underwent positive selection in three of the domestic mammals. Our data provide an insight into adaptive evolution of high-altitude domestic mammals, and should facilitate the search for additional novel genes involved in the hypoxia response pathway.  相似文献   

The debate over the National Curriculum for history in England and Wales, 198990: the role of the press     

Gareth Elwyn Jones 《Curriculum Journal》2013,24(3):299-322

The construction of a history curriculum for England and for Wales under the terms of the 1988 Education Reform Act occasioned more debate in the media than any other subject in the National Curriculum. The links between the content of a history syllabus and perceptions within both nations of the part this plays in moulding national spirit made this inevitable. The disparity of view between the two groups charged with devising the syllabus and the government, particularly the Prime Minister, heightened the tension. This article explores the way in which consequent political, professional and public discussion was covered in the whole range of national newspapers. It is argued that the failure of the London press to comprehend the situation in Wales reduced significantly its appreciation of the processes involved in the making of the history curriculum.  相似文献   

Observing response processes with eye tracking in international large-scale assessments: evidence from the OECD PIAAC assessment     

Bryan Maddox  Andrew P. Bayliss  Piers Fleming  Paul E. Engelhardt  S. Gareth Edwards  Francesca Borgonovi 《European Journal of Psychology of Education - EJPE》2018,33(3):543-558

This paper reports on a pilot study that used eye tracking techniques to make detailed observations of item response processes in the OECD Programme for the International Assessment of Adult Competencies (PIAAC). The lab-based study also recorded physiological responses using measures of pupil diameter and electrodermal activity. The study tested 14 adult respondents as they individually completed the PIAAC computer-based assessment. The eye tracking observations help to fill an ‘explanatory gap’ by providing data on variation in item response processes that are not captured by other sources of process data such as think aloud protocols or computer-generated log files. The data on fixations and saccades provided detailed information on test item response strategies, enabling profiling of respondent engagement and response processes associated with successful performance. Much of that activity does not include the use of the keyboard and mouse, and involves ‘off-screen’ use of pen and paper (and calculator) that are not captured by assessment log-files. In conclusion, this paper points toward an important application of eye tracking in large-scale assessments. This includes insights into response processes in new domains such as adaptive problem-solving that aim to identify individuals’ ability to select and combine resources from the digital and physical environment.  相似文献   

‘Hot’, ‘Cold’ and ‘Warm’ supports: towards theorising where refugee students go for assistance at university     

Sally Baker  Georgina Ramsay  Evonne Irwin  Lauren Miles 《Teaching in Higher Education》2018,23(1):1-16

This paper contributes a rich picture of how students from refugee backgrounds navigate their way into and through undergraduate studies in a regional Australian university, paying particular attention to their access to and use of different forms of support. We draw on the conceptualisation of ‘hot’ and ‘cold’ knowledge, offered by Ball and Vincent (1998. “‘I Heard it on the Grapevine’: ‘Hot’ Knowledge and School Choice.” British Journal of Sociology of Education 19 (3): 377–400), and the addition of ‘warm’ knowledge offered by Slack et al. (2014. “‘Hot’, ‘Cold’ and ‘Warm’ Information and Higher Education Decision Making.” British Journal of Sociology of Education 35 (2): 204–223), to develop an understanding of how students from refugee backgrounds make choices about how they locate, select and access support for their studies. The findings of this paper suggest that students from refugee backgrounds do not view the ‘cold’ (unfamiliar-formal) institutional support on offer as ‘for them’; instead they expressed a preference for the ‘warm’ (familiar-formal) support offered via ‘trusted’ people who act as literacy/sociocultural brokers or ‘hot’ (familiar-informal) support of their grapevine of other students (past and present) or experienced community members.  相似文献
