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   

Gender differences in the junior secondary (grade 7) mathematics curriculum in Hong Kong     

K. C. Cheung 《Educational Studies in Mathematics》1989,20(1):97-103

This article seeks to examine gender differences across the mathematics curriculum in the various topic areas and mathematical abilities. It is suggested that a profile of these differences, when compared with students at different grade levels or across curricula, would be more fruitful for classroom teachers and curriculum developers. Breakdown and discriminant function statistics reveal that boys performed better than girls in Geometry and excelled in comprehension, and solving routine and non-routine problems. Girls were better at mathematical manipulation problems.  相似文献   

Nationalistic Education in a Post-colonial Age: the Impact of Study Trips to China and the Development of Hong Kong Students' National Identity     

Sammy King-fai Hui  Frankie Ka-ki Cheung  Yama Yuk-ngo Wong 《Asia Pacific Journal of Education》2004,24(2):205-224

With the return of its sovereignty to the People's Republic of China (PRC) on 1 July 1997, Hong Kong attained a new political status as a Special Administrative Region. Hong Kong students, under British rule, had long been receiving de-politicised education, and a sense of belonging to China was limited to the cognitive domain of Chinese history. The ideal of promoting national identity, underpinned in the current civic education curriculum, is proving to be a difficult task. While much literature has documented how curriculumbased educational practices fail to instil students with such an identity, little study has been undertaken to suggest effective alternatives and to examine how they work. This paper reports a study investigating the impact of study trips on developing students' national identity. Through observation and interviews, it takes an in-depth look into students' experience, into how they identify with a Chinese identity. Results indicate that though the study trips help to nurture the cognitive and affective dimensions of national identity, there are limits and possibilities involved. This paper concludes with reminders which teachers should have taken into account when thinking of using co-curricular activities to address the legitimate need of fostering nationalistic education.  相似文献

Core-shell hydrogel beads with extracellular matrix for tumor spheroid formation     

L. Yu  S. M. Grist  S. S. Nasseri  E. Cheng  Y.-C. E. Hwang  C. Ni  K. C. Cheung 《Biomicrofluidics》2015,9(2)

Creating multicellular tumor spheroids is critical for characterizing anticancer treatments since they may provide a better model of the tumor than conventional monolayer culture. Moreover, tumor cell interaction with the extracellular matrix can determine cell organization and behavior. In this work, a microfluidic system was used to form cell-laden core-shell beads which incorporate elements of the extracellular matrix and support the formation of multicellular spheroids. The bead core (comprising a mixture of alginate, collagen, and reconstituted basement membrane, with gelation by temperature control) and shell (comprising alginate hydrogel, with gelation by ionic crosslinking) were simultaneously formed through flow focusing using a cooled flow path into the microfluidic chip. During droplet gelation, the alginate acts as a fast-gelling shell which aids in preventing droplet coalescence and in maintaining spherical droplet geometry during the slower gelation of the collagen and reconstituted basement membrane components as the beads warm up. After droplet gelation, the encapsulated MCF-7 cells proliferated to form uniform spheroids when the beads contained all three components: alginate, collagen, and reconstituted basement membrane. The dose-dependent response of the MCF-7 cell tumor spheroids to two anticancer drugs, docetaxel and tamoxifen, was compared to conventional monolayer culture.  相似文献   

Integrating Creative Thinking Skills Pedagogies into a Higher Education Visual Arts Course     

Cheung On Tam 《The International Journal of Art & Design Education》2023,42(1):16-32

Although there has been increasing international emphasis on creativity in education, many creativity training programmes have focused on enhancing students' creative thinking skills with few studies on how these skills can be integrated into the teaching of subject disciplines. As a member of a Community of Practice project that ran from spring 2021 to summer 2022 at my university, I worked with ten university teachers from multiple disciplines to develop and implement instructional strategies to foster students' creative thinking skills. The paper documented the development, implementation and evaluation of creative thinking skills teaching strategies for a higher education course in visual arts. Both the development of the teaching strategies and the measurement of the impact on student learning have undergone vigorous research procedures and made reference to the existing literature. The effectiveness of the activities was assessed using multiple methods including the Torrance Test of Creative Thinking, a self-report inventory, and a focus group interview. The results indicated the new learning activities enhanced students' creative thinking skills. They also showed that creativity can be developed through teaching while revealing that playfulness, freedom and structure, group interactions, and problem-solving activities are beneficial for the development of creative thinking skills. Readers may better understand the different ways in which creative thinking skills instruction materials can be developed and incorporated into teaching of visual arts by making reference to the strategies suggested and the process of development in the paper.  相似文献   

The Perfect Marriage? – Language and Art Criticism in the Hong Kong Public Examination Context          下载免费PDF全文

Chung‐yim Lau  Cheung‐on Tam 《The International Journal of Art & Design Education》2017,36(1):61-70

Art education in Hong Kong has undergone various changes in response to educational reform. In art assessment, a major change in the Hong Kong New Senior Secondary (NSS) Curriculum is the inclusion of art criticism as a compulsory component of the new public examination. Assessing students’ abilities to interpret art in an art criticism public examination context is a critical issue in Hong Kong because the new senior secondary curriculum and assessment has brought attention to the role of written language in the art examination paper. This means the examination assesses not only students’ abilities to interpret art, but also their language abilities required to respond to art in written form. Since this new mode of assessment of art criticism has been published a number of issues have appeared. Recent studies show that teachers and students perceive this development negatively and they believe that the written format will assess students’ written language abilities rather than their critical abilities. These findings challenge the justification of the new art assessment policy and raise questions about the role of written language in responding to art. This article aims to raise the issue of the marriage between language and art criticism in the Hong Kong public examination context. It argues and examines the relationship of language to art interpretation, reasoning in the assessment, and issues in the public art criticism examination context. The issues addressed in this article provide opportunities for researchers and policy makers to reconsider and refine the new form of examination.  相似文献

Homophobia in medical students of the University of Hong Kong     

R. W. M. Kan  K. P. Au  W. K. Chan  L. W. M. Cheung  C. Y. Y. Lam  H. H. W. Liu 《Sex education》2013,13(1):65-80

Homosexuality is now accepted as a normal variant of human sexuality, but homophobia among healthcare professionals is well documented. Establishment of trustful doctor–patient relationships is impossible in the presence of homophobia. We were interested to examine the extent of homophobia among medical students, the future doctors. This article aims to study attitudes of medical students of the University of Hong Kong towards homosexuality and to identify significant factors affecting their attitudes. A cross‐sectional study was performed on students of the University of Hong Kong. Attitudes towards homosexuality were compared between medical and non‐medical students. More than 25% of the medical students agreed with the statement ‘homosexuality is a psychological disorder that requires therapy’. More than 15% would avoid any physical contact with homosexuals to minimise the chance of contracting diseases, especially AIDS. Comparison between the medical students and non‐medical students showed that the attitudes of the medical students were significantly more homophobic. Factors explaining the difference included the importance of religion in the formation of moral values, gender, experience of working closely with homosexual friends, sexual orientation, experience of the heterosexual sexual act, acquaintance of homosexual friends, and experience of homosexual love relationships. In conclusion, there appeared to be a certain level of homophobia among the medical students. This could possibly be explained by their lack of experience of working closely with homosexual friends. Relevant curriculum modification and development are urgently needed, to provide ongoing opportunities for students to realise their own values that could unconsciously affect their clinical judgements.  相似文献   

A Two-Stage Approach to Synthesizing Covariance Matrices in Meta-Analytic Structural Equation Modeling     

Mike W.L. Cheung  Wai Chan 《Structural equation modeling》2013,20(1):28-53

A great obstacle for wider use of structural equation modeling (SEM) has been the difficulty in handling categorical variables. Two data sets with known structure between 2 related binary outcomes and 4 independent binary variables were generated. Four SEM strategies and resulting apparent validity were tested: robust maximum likelihood (ML), tetrachoric correlation matrix input followed by SEM ML analysis, SEM ML estimation for the sum of squares and cross-products (SSCP) matrix input obtained by the log-linear model that treated all variables as dependent, and asymptotic distribution-free (ADF) SEM estimation. SEM based on the SSCP matrix obtained by the log-linear model and SEM using robust ML estimation correctly identified the structural relation between the variables. SEM using ADF added an extra parameter. SEM based on tetrachoric correlation input did not specify the data generating process correctly. Apparent validity was similar for all models presented. Data transformation used in log-linear modeling can serve as an input for SEM.  相似文献
