Syntactic and discourse skills in Chinese adolescent readers with dyslexia: a profiling study

This study aims to investigate the relation of syntactic and discourse skills to morphological skills, rapid naming, and working memory in Chinese adolescent readers with dyslexia and to examine their cognitive–linguistic profiles. Fifty-two dyslexic readers (mean age, 13;42) from grade 7 to 9 in Hong Kong high schools were compared with 52 typically developing readers of the same chronological age (mean age, 13;30) in the measures of word reading, 1-min word reading, reading comprehension, morpheme discrimination, morpheme production, morphosyntactic knowledge, sentence order knowledge, digit rapid naming, letter rapid naming, backward digit span, and non-word repetition. Results showed that dyslexic readers performed significantly worse than their peers on all the cognitive-linguistic tasks. Analyses of individual performance also revealed that over half of the dyslexic readers exhibited deficits in syntactic and discourse skills. Moreover, syntactic skills, morphological skills, and rapid naming best distinguished dyslexic from non-dyslexic readers. Findings underscore the significance of syntactic and discourse skills for understanding reading impairment in Chinese adolescent readers.     

The Mediating Effect of Knowledge‐Sharing Processes on Organizational Cultural Factors and Knowledge Management Effectiveness

This study explored the extent to which knowledge‐sharing processes mediate organizational cultural factors and knowledge management effectiveness among Korean organizations. The findings show that knowledge‐sharing processes play as mediators in the effect of trust, collaboration, and learning on knowledge management effectiveness. Employees from knowledge management practicing companies in Korea were surveyed. Results from mediation analysis show that knowledge‐sharing processes have both practical and statistical significance to enhance knowledge management effectiveness. Trust and a learning culture are also significant to increase knowledge management effectiveness. We discuss the implications of these findings to facilitate knowledge sharing and make suggestions for future research.

Worldviews,religions, and beliefs about teaching and learning: perception of mathematics teachers with different religious backgrounds

Beliefs about mathematics education and their influences on teaching practices have been widely investigated in recent decades. There have been numerous empirical studies on the influences of religions on teachers’ and students’ beliefs about subjects such as sciences and language. However, the influences of worldviews in general and religions in particular, as one of the major sources of beliefs in relation to mathematics education, are under-researched. The current study is a first step to unpacking the relationship between teachers’ religions and their beliefs about mathematics teaching and learning. By means of semi-structured interviews with mathematics teachers of different religious backgrounds, teachers’ perceptions on the connection between their personal religious beliefs and their beliefs about teaching and learning are investigated. In-depth analyses of the perceptions of three mathematics teachers reveal the complex relationship between teachers’ religious beliefs and their teaching beliefs. First, there are some common values shared by different religions, which influence the beliefs about mathematics teaching and learning as well as education in general. Second, religion is a rich belief system, and the teachers appear to apply only a portion of their religious beliefs to guide their teaching. It is also possible that a teacher is influenced by more than one religion or cultural tradition. Despite its subtleties, our study provides evidence to support the alignment between teachers’ personal religious beliefs and their beliefs about mathematics teaching and learning.     

The politics of collaboration: discourse,identities, and power in a school–university partnership in Hong Kong

This article reports on how teacher educators from a university, acting as facilitators, supported teachers in conducting a school-based action research project as a practice of professional development in the context of reform in language assessment in Hong Kong. In particular, the article problematises how the facilitators and teachers negotiated and managed identities whilst being engaged in a collaborative action research project. Data were collected from semi-structured interviews. Critical discourse analysis was used to examine the textual data. A key finding was that identities were neither fixed nor finite in the context of collaboration, but were negotiated within and against a range of contextually salient discourses. A major contribution of the article lies in its examination of the complexities of negotiating identities when educators from two different institutional cultures collaborate. The article suggests that collaboration has to be understood within broader sociocultural contexts to identify the interplay of forces that shape relations, identities, and practices constructed.

Assessing College Student-Athletes' Life Stress: Initial Measurement Development and Validation

College student-athletes have unique life stress that warrants close attention. The purpose of this study was to develop a reliable and valid measurement assessing college student-athletes' life stress. In Study 1, a focus group discussion and Delphi method produced a questionnaire draft, termed the College Student-Athletes' Life Stress Scale. In Study 2 and Study 3, the properties of the items and the underlying structure of the College Student-Athletes' Life Stress Scale were confirmed through item analysis, factor analysis, and reliability examination. A 24-item College Student-Athletes' Life Stress Scale with eight factors was established. In addition, examining concurrent and discriminant validity via correlations among College Student-Athletes' Life Stress Scale, positive state of mind, and burnout experiences provided further evidences of criterion validity. Across these phases, results showed adequate factorial structure, criterion validity, and reliability of the College Student-Athletes' Life Stress Scale. The investigators suggest that College Student-Athletes' Life Stress Scale could be used as a tool for researchers and practitioners to assess college student-athletes' life stress.     

Understanding teachers’ will and capacity to accomplish physical education curriculum reform: the implications for teacher development

Drawing on data generated by a two-year ethnographic study in a high security Spanish prison, this article explores the multiple meanings given to the social practices of sport and physical activity. We provide details of the following key themes that emerged from the analysis: (a) escaping time; (b) perceived therapeutic benefits; (c) social control; (d) gendered dimensions; and (e) performing masculinity. The findings suggest that a diverse and contradictory set of meanings are associated with sport and physical activity within this particular prison culture, and that the performance of specific kinds of masculinity is both a process and product that shapes the construction of experience in powerful ways.     

Maximum oxygen uptake and body composition of healthy Hong Kong Chinese adult men and women aged 20 – 64 years

Abstract

The aims of the present study were to assess the maximal oxygen uptake and body composition of adult Chinese men and women, and to determine how these variables relate to age. The cross-sectional sample consisted of 196 men and 221 women aged 20 – 64 years. Maximal oxygen uptake ([Vdot]O_2max) was determined by indirect calorimetry during a maximal exercise test on an electrically braked cycle ergometer. The correlations between [Vdot]O_2max and fat mass were ?0.52 in men and ?0.58 in women. Linear regression defined the cross-sectional age-related decline in [Vdot]O_2max as 0.35 ml · kg^?1 · min^?1 · year^?1 in men and 0.30 ml · kg^?1 · min^?1 · year^?1 in women. Multiple regression analysis showed that more than 50% of this cross-sectional decline in [Vdot]O_2max was due to fat mass, lean mass, and age. Adding fat mass and lean mass to the multiple regression models reduced the age regression mass from 0.35 to 0.24 ml · kg^?1 · min^?1 · year^?1 in men and from 0.30 to 0.15 ml · kg^?1 · min^?1 · year^?1 in women. We conclude that age, fat mass, and lean mass are independent determinants of maximal oxygen uptake in Chinese adults.     

The biomechanics of soccer: A review

Abstract

The purpose of this investigation was to determine whether combining two mental preparation strategies would be more effective in enhancing performances than a single strategy. Subjects (n = 40) practiced on a basketball free throw task (20 shots) using one of the following mental preparation strategies: (a) imagery, (b) relaxation, (c) relaxation plus imagery, (d) placebo control. To simulate game conditions, subjects were allowed only 10 s in which to use their mental preparation strategy. After the practice session, subjects shot 20 test free throws using their designated technique. Results indicated a significant main effect with the imagery group performing significantly better than the placebo control group although there were no specific differences between the three experimental groups. The results are discussed in terms of potential variables mediating the effectiveness of imagery in enhancing sport performance, and future directions for research are offered.
