Increasing plantarflexion angle during landing reduces vertical ground reaction forces,loading rates and the hip’s contribution to support moment within participants     

K. Michael Rowley  James G. Richards 《Journal of sports sciences》2015,33(18):1922-1931

The ankle joint’s role in shock absorption during landing has been researched in many studies, which have found that landing with higher amounts of plantarflexion (PF) results in lower peak vertical ground reaction forces and loading rates. However, there has not yet been a study that compares drop landings within participants along a quantitative continuum of PF angles. Using a custom-written real-time feedback program, participants adjusted their ankles to an instructed PF angle and dropped onto two force platforms. For increasing PF, peak ground reaction force and peak loading rate during weight acceptance decreased significantly. The hip’s contribution to peak support moment decreased as PF at initial contact increased up to 30°. The ankle and knee contributions increased over this same continuum of PF angles. There appears to be no optimal PF angle based on peak ground reaction force and loading rate measurements, but there may be an optimum where joint contributions to peak support moment converge and the hip moment’s contribution is minimised.  相似文献   

A longitudinal examination of African American adolescents' attributions about achievement outcomes     

Swinton AD  Kurtz-Costes B  Rowley SJ  Okeke-Adeyanju N 《Child development》2011,82(5):1486-1500

Developmental, gender, and academic domain differences in causal attributions and the influence of attributions on classroom engagement were explored longitudinally in 115 African American adolescents. In Grades 8 and 11, adolescents reported attributions for success and failure in math, English and writing, and science. In Grade 11, English and mathematics teachers rated students' classroom engagement. Boys were more likely than girls to attribute math successes to high ability and to attribute English failures to low ability. Both genders' ability attributions for math became more negative from eighth to eleventh grades. Grade 8 attributions of math failure to lack of ability were negatively related to Grade 11 math classroom engagement. Results illustrate the gendered nature of motivational beliefs among Black youth.  相似文献   

Factors affecting attitudes and intentions towards knowledge sharing in the Dubai Police Force     

Ibrahim Seba  Jennifer Rowley  Sian Lambert 《International Journal of Information Management》2012

This study contributes to the limited research base on knowledge sharing in public sector organisations, specifically police forces, and organisations in the Middle East through a case study investigation into the factors that affect knowledge sharing in the Dubai Police Force. A questionnaire-based survey was conducted with staff in key departments in the Dubai Police Force. Informed by the literature and by interviews conducted in a previous phase, the core of the questionnaire was a bank of Likert-style questions covering the dependent variables intention to knowledge share, and attitude towards knowledge sharing, and the independent variables, trust, organisational structure, leadership, reward, time, and information technology. Data was analysed using structured equation modelling, in order to test the measurement model using confirmatory factor analysis, and to test the structural model. The structural model suggests a strong relationship between attitude to knowledge sharing, and intention to share knowledge. Hypotheses regarding the influence of leadership, trust, organisational structure, time, and information technology on attitude to knowledge sharing were upheld. Rewards did not to influence attitude to knowledge sharing. Recommendations are offered for practice and further research.  相似文献   

Editorial     

Avril Loveless 《Technology, Pedagogy and Education》2013,22(1):3-6

This paper analyses the experience of a teacher and her Year 6 class (10–11 year‐olds) over a school year, while participating in a pilot project introducing Personal Digital Assistants as a learning tool. The intervention was initiated and supported by the local City Learning Centre, which was concerned with how best to use technologies for learning, and the teacher was prepared to take risks to learn how to use the technology and apply it within the national curriculum. This paper focuses on the roles the teacher played in designing, managing and mediating multi‐modal approaches to teaching and learning, while meeting the curriculum requirements. Her creative approach was rewarded with high levels of student engagement, motivation and autonomy across the class, and higher than expected results in the national tests.  相似文献

Making a Difference? An Evaluation of Professional Knowledge and Pedagogy in Art and ICT     

Avril Loveless 《The International Journal of Art & Design Education》2003,22(2):145-154

The paper presents a research perspective on a Secondary school‐based project,, Art on the Net, which explored the interaction between practising artists, students and teachers using digital technologies in the visual and performance arts in school settings. The study illustrated the role that art education plays not only in providing an authentic context for the use of digital technologies, but also in offering insights into conceptualising the nature of ICT capability. The analysis for this paper highlights key themes arising for participants engaged in such intervention projects and illustrates the interaction between professional knowledge and pedagogy in Art and ICT.  相似文献

Computer-graphics and the literary construct: a learning method     

Avril Henry 《British journal of educational technology : journal of the Council for Educational Technology》2002,33(1):7-15

This paper describes a third-year undergraduate module, Text Through Images (TTI; known at first as Texts with Computers) which ran for some years in the School of English, University of Exeter, UK. Instead of using only words, TTI students made their own computer graphics both to discover and to describe literary structures in texts of their choice. The results were surprising: whatever their “academic” ability, students on this course regularly produced genuinely original literary perceptions, and their natural creativity was released. The module's innovative methods are eminently transferable to other disciplines. This paper is designed to be read in conjunction with a website: for further details, go to http://www.blackwellpublishers.co.uk/asp/journal.asp?ref=0007-1013 presenting a selection of students' graphics produced on the course; these appear by generous permission of their makers, who hold copyright. The reasons for the module's success are elusive. Perhaps students feel unfettered by the attitudes associated with traditional verbal expression, the absence of preconceptions about the new process enabling them to bypass old habits of thought. Perhaps the interplay of word and image is particularly fruitful because images and words activate different areas of the brain. It may be that the computer creates the illusion of distance between design and designer, so that the latter feels less personally exposed than when drawing on paper. Perhaps success lies in the combination of individual freedom and on-screen group work, or on the way in which students are enabled to make small but publishable original discoveries. Educational psychologists may be able to explain why the mix works (it has been suggested that it represents a “constructivist/generative learning strategy that Dave Jonassen terms ‘elaboration’”) but more importantly, teachers may find the model useful. What interests me about the module is not the structure of the teaching, but the way in which the use of diagramming apparently enables the learner productively to bypass previous mental conditioning about how literature works, and what is acceptable in analysing it.  相似文献   

Do we need more male primary teachers? Tensions and contradictions in the perspectives of male and female trainees     

Colette Ankers de Salis  Avril Rowley  Kathy Stokell 《Education 3-13》2019,47(4):475-489

Primary teaching Initial Teacher Training courses across the UK have been under pressure from central government, Ofsted and the media to recruit more male students to their courses with the aim of increasing the proportion of males in the primary teaching workforce. This is because increasing the number of male role models in primary schools has been mooted as the solution to boys’ underachievement, especially in reading and writing. There is, however, little evidence showing any correlation between boys’ educational outcomes and the number of male primary teachers in schools. The purpose of the project reported in this paper was to ascertain the beliefs of the future primary school workforce about this focus on the need for male role models in schools. A mixed-methods approach was employed: 120 male and female primary trainees were surveyed and a further 48 took part in group interviews, all of whom were based in an Initial Teacher Training department in a university in North West England. Results indicated that although aspiring teachers felt that males and females could make equally good role models for children their personal value systems perpetuated the myth that boys need male role models to achieve better educational outcomes.  相似文献
