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   

Mechanisms of the relation between perinatal problems, early childhood illness, and psychopathology in late childhood and adolescence   总被引：6，自引：0，他引：6  

P Cohen  C N Velez  J Brook  J Smith 《Child development》1989,60(3):701-709

Data on perinatal and early childhood somatic and psychological risk factors of a random sample of children were gathered in early to middle childhood and employed to examine the long-term risk of emotional and behavioral problems of late childhood and adolescence. 3 issues were addressed: First, can syndromic specificity of such effects be identified on scaled and diagnostic measures of syndromes? Second, are these effects attributable to excess risk of low-income children for both perinatal and later childhood problems? Third, are the intervening mechanisms identifiable as intellectual impairment, vulnerability to poor health, poor maternal caretaking, maternal rejection, or maternal stress associated with marital problems? Findings indicated that elevated risk was present for all syndromes, both at the scale level and at the diagnostic level. None of the examined intervening mechanisms fully accounted for the effects of early risks.  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

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
