Compared to competitive runners, recreational runners appear to be more prone to injuries, which have been associated with foot strike patterns. Surprisingly, only few studies had examined the foot strike patterns outside laboratories. Therefore, this study compared the foot strike patterns in recreational runners at outdoor tracks with previously reported data. We also investigated the relationship between foot strike pattern, speed, and footwear in this cohort. Among 434 recreational runners analysed, 89.6% of them landed with rearfoot strike (RFS). Only 6.9 and 3.5% landed with midfoot and forefoot, respectively. A significant shift towards non-RFS was observed in our cohort, when compared with previously reported data. When speed increased by 1 m/s, the odds of having forefoot strike and midfoot strike relative to RFS increased by 2.3 times and 2.6 times, respectively. Runners were 9.2 times more likely to run with a forefoot strike in minimalists compared to regular running shoes, although 70% of runners in minimalists continued to use a RFS. These findings suggest that foot strike pattern may differ across running conditions and runners should consider these factors in order to mitigate potential injury.  相似文献   

Degrees of value: comparing the contextual complexities of UK transnational education in Malaysia and Hong Kong     

I Lin Sin  Maggi W. H. Leung  Johanna L. Waters 《Compare》2019,49(1):132-148

This paper reveals the complex diversity that underpins ostensibly similar transnational education programmes (TNE), through a comparison of UK TNE in Malaysia and Hong Kong. It draws on data from two different yet cognate studies on the role of UK universities in delivering higher education in Asia. Some fine-grained and informative differences between the ways in which ‘value’ in TNE is constructed in different host contexts is revealed. The paper brings to light the ‘voices’ of TNE students and graduates, which are very seldom heard. The arguments adapt and extend the concepts of education as a positional good, and as cultural capital. For various instrumental, intrinsic and personal reasons the authors discuss in detail, UK TNE is more highly valued in Malaysia than in Hong Kong. The paper makes a wider contribution to knowledge on the changing landscape of international higher education and the impact on social and personal (dis)advantage.  相似文献   

A symplectic eigensolution method in transversely isotropic piezoelectric cylindrical media     

徐新生 顾佥梁以德  郑建军 《浙江大学学报(A卷英文版)》2005,6(9):922-927

INTRODUCTION Since the phenomenon of piezoelectricity in natural crystals was discovered in 1880, it has been applied in many fields, such as smart structure, sensing devices and active control, because of its special properties. Combining electrical behavior with mechanical deformation is the special property which attracted great interest of researchers. Many models have been developed for studying piezoelec- tric effects. Dunn and Wienecke (1996) used Green’s functions for transverse…  相似文献   

Cumulative stress and substantiated maltreatment: the importance of caregiver vulnerability and adult partner violence   总被引：1，自引：0，他引：1  

Wekerle C  Wall AM  Leung E  Trocmé N 《Child abuse & neglect》2007,31(4):427-443

OBJECTIVE: Our goal is to assess the effect of caregiver vulnerabilities, singly and in combination, on the substantiation of child abuse (physical, sexual) and neglect, while controlling for relevant background variables. We test the moderator role of adult partner violence in qualifying the relationship between caregiver vulnerabilities and maltreatment substantiation. METHOD: Secondary analyses of the 1998 Canadian Incidence Study of Reported Child Maltreatment (CIS) are used to predict child protective service investigation substantiation versus non-substantiation from a range of caregiver vulnerability factors. Involvement in partner violence was examined as a moderator in the relation between caregiver vulnerabilities and maltreatment substantiation. The CIS is an epidemiological survey of first-reported cases to child protective services, using a random sample of child welfare agencies across Canada. Child welfare workers completed a research form on the child, primary caregiver, family, perpetrator, severity and type of maltreatment, as well as services and court outcomes. All maltreatment classifications were assigned according to the Canadian legal definition of child abuse and neglect. Hierarchical logistic regression analyses were used, with stepped entry of: (1) demographic factors, socioeconomic disadvantage, and caregiver's own history of maltreatment; (2) caregiver vulnerability factors; (3) involvement in partner violence; (4) the interaction between caregiver vulnerability and partner violence. RESULTS: Caregiver substance abuse was found to be the single most potent kind of caregiver vulnerability in predicting maltreatment substantiation. When the total number of vulnerabilities was used as the predictor, prediction across all types of maltreatment increased, especially for substantiated neglect. Analyses also showed that the presence of partner violence in the home exacerbated the effect of caregiver vulnerability on substantiation. CONCLUSIONS: The total number of caregiver vulnerabilities was the best predictor of the substantiation of child abuse and neglect. This relationship was moderated by the existence of partner violence: high caregiver vulnerability and high partner violence increased the likelihood of substantiation versus non-substantiation. These results suggest that caregiver issues should be considered in tandem with partner relationships. Among child welfare cases, caregiver vulnerability and partner violence are critical targets for child maltreatment prevention and early child protective services intervention.  相似文献

Look who's coming to school: the Emirati student voice in an intervention‐based study on inclusion of learners with intellectual disabilities in Emirati mainstream government schools          下载免费PDF全文

Eman Gaad 《Journal of Research in Special Educational Needs》2015,15(2):130-138

Although there are many factors that can affect the success of the inclusion of students with disabilities in mainstream schools, the attitude of typically developing peers towards peers with disabilities is one of the critical factors leading to success. This study examines the effects of a planned intervention on the attitudes of the typically developing peers related to their perceptions about students with intellectual disabilities during a half‐day workshop which took place in each of the target schools and their opinions about including these students in mainstream schools in the United Arab Emirates. The intervention involved both a presentation about the abilities of persons with intellectual disabilities and an opportunity for personal interaction with these students. Following the intervention, the subjects were interviewed and their responses analysed. The results showed that after the intervention, most typically developing students had gained a basic knowledge of intellectual disability which affected their expectations for the abilities of same‐age learners with intellectual disabilities and their acceptance of their inclusion in the mainstream school. Analysis of the responses of the typically developing peers also indicated that the intervention had a positive effect which can lead to a change in attitudes towards possible inclusion of such students in their schools. For future practice and further research, recommendations are made to assist decision makers in this field.  相似文献

Pity and Justice in Rousseau's Emile: Developing a Concern for the Common Good     

Wing Sze Leung 《Educational theory》2023,73(1):74-89

Scholarly accounts of the training of pity in Jean-Jacques Rousseau's Emile focus on how Emile's tutor activates the psychological mechanisms necessary for the feeling of pity in book 4 of the text. This account is inadequate, for it fails to show how Emile acquires the evaluative ability to make the judgment about who deserves pity as well as the willingness to adjudicate his own and others' interests. In this article, Wing Sze Leung argues that books 1 through 3 lay the foundation by developing in Emile the attitudes and dispositions that guide him in his judgment-making about which kind of life he should pursue. Books 4 and 5 then develop Emile's ability to make interpersonal judgments of pity through habituated practice. By gradually cultivating Emile's sensitivity to the potential conflict between his self-interests and others' well-being, as well as the resolution to refrain from infringing on others' interests and to pursue the common good, Rousseau's long-term educational project molds Emile's disposition to act as justice demands. The article concludes with a brief response to some criticisms about Rousseau's educational project.  相似文献   

Childhood fears among children who are blind: the perspective of teachers who are blind     

Eman Al-Zboon 《Early Years: An International Journal of Research and Development》2017,37(2):158-172

The aim of this study was to investigate childhood fears in children who are blind from the perspective of teachers who are blind. The study was conducted in Jordan. Forty-six teachers were interviewed. Results revealed that the main fear content in children who are blind includes fear of the unknown; environment-, transportation- and people-related fear; and fear of animals. The teachers reported that the reasons for fear in children with visual impairment include child-related reasons (internal reasons), lack of training (hearing, social skills, orientation and mobility [O&M] and tactile training), family factors and an unsuitable physical environment. O&M training, independence training, family counselling and environment adaptation were reported to be the best procedures to deal with fear in these children. Recommendations are provided in the light of the study.  相似文献   

Jordanian parents’ beliefs about the causes of disability and the progress of their children with disabilities: insights on mainstream schools and segregated centres     

Kholoud Adeeb Al-Dababneh  Eman K. Al-Zboon  Haitham Baibers 《欧洲特需教育杂志》2017,32(3):362-376

This study aims to identify the beliefs of Jordanian parents of children with disabilities (CWD), including intellectual disabilities, specific learning disorders and Autism Spectrum Disorder: both in terms of the causes of these disabilities, and the ability of their children to make progress. A qualitative interpretive methodology was employed. Interviews were used to collect data from 63 parents of CWD. Two major themes emerged concerning beliefs about the causes of disability and children’s progress. Results showed generally that disabilities were attributed to supernatural and biomedical causes; also, most parents had positive expectations about their children’s progress, especially in education skills, and had hopes for their children’s futures. Conclusions and implications are presented in the light of the study findings.  相似文献
