Prevalence and correlates of physical abuse in Hong Kong Chinese adolescents: a population-based approach.

OBJECTIVE: The objectives were to estimate the prevalence and correlates of physical abuse-related outcomes in the family setting in Hong Kong's adolescent population. METHOD: A cross-sectional study design was used. A randomly selected sample of 3,355 secondary school students in Kwai Tsing District of Hong Kong was surveyed. The response rate was 98%. RESULTS: The prevalence rates of corporal punishment, being beaten by parents for no apparent reason, being beaten to injury by family members in the past 3 months and any one of the above three were 4.9% (95% CI, 4.2% to 5.6%), 2.0% (95% CI, 1.5% to 2.5%), 1.1% (95% CI, .98% to 1.2%) and 6.6% (95% CI, 5.7% to 7.5%), respectively. Students who had experienced the above physical abuse-related outcomes were at a significant disadvantage for a wide range of morbidity indicators, including self-perceived bad health, anxiety and stress, somatic illnesses (such as asthma and epigastric pain), injuries and accidents, and hospitalization. They were more likely to have poor familial relations and coping skills, and to take up habits which potentially put their health at risk, such as smoking, alcohol consumption, and fighting with others. CONCLUSIONS: Our prevalence estimates of physical abuse in the family setting for a student population in Hong Kong is an improvement over previous local estimates of physical abuse occurrence, which were mainly based on case notifications and clinical samples. The results also show that the abused adolescents are growing up in an environment filled with physical, psychological, and familial adversities.     

Scalable volumetric imaging for ultrahigh-speed brain mapping at synaptic resolution

The speed of high-resolution optical imaging has been a rate-limiting factor for meso-scale mapping of brain structures and functional circuits, which is of fundamental importance for neuroscience research. Here, we describe a new microscopy method of Volumetric Imaging with Synchronized on-the-fly-scan and Readout (VISoR) for high-throughput, high-quality brain mapping. Combining synchronized scanning beam illumination and oblique imaging over cleared tissue sections in smooth motion, the VISoR system effectively eliminates motion blur to obtain undistorted images. By continuously imaging moving samples without stopping, the system achieves high-speed 3D image acquisition of an entire mouse brain within 1.5 hours, at a resolution capable of visualizing synaptic spines. A pipeline is developed for sample preparation, imaging, 3D image reconstruction and quantification. Our approach is compatible with immunofluorescence methods, enabling flexible cell-type specific brain mapping and is readily scalable for large biological samples such as primate brains. Using this system, we examined behaviorally relevant whole-brain neuronal activation in 16 c-Fos-shEGFP mice under resting or forced swimming conditions. Our results indicate the involvement of multiple subcortical areas in stress response. Intriguingly, neuronal activation in these areas exhibits striking individual variability among different animals, suggesting the necessity of sufficient cohort size for such studies.     

Reflections through a local lens on Muto Ichiyo's ideas of alternative practices: a Hong Kong perspective

This paper discusses the views of Muto Ichiyo, an important thinker and social activist in Japan and the Inter-Asian context, on alternative practices through reviewing the actual implementation of several community projects in Hong Kong and mainland China. Many of these community projects are informed by visions and notions of alternative practices of, say, a “Muto type”—constructing a new democratic experience, locally rooted and globally connected, which will contribute to a transformed and transformative socio-cultural structure/relation that is non-statist and non-capitalist in nature. Through scrutinizing the effectiveness of these projects in local contexts, we hope to facilitate a dialogue with Muto on his notions of “transborder alliance of people/hope” and “alternative development”.     

Benefits of a physical activity intervention for men with prostate cancer

The purpose of the current study was to examine the viability of conducting a theory-based physical activity (PA) intervention on men with prostate cancer, and the impact of PA on quality of life (QOL). Participants were 31 men, average age of 67 years, with localized or metastatic prostate cancer undergoing androgen deprivation therapy (ADT). Global QOL, fatigue, and PA measures were conducted at baseline and following the 12-week intervention. An additional follow-up testing was conducted 4 months following the intervention (n = 18). Both moderate and strenuous bouts of exercise, as well as functional capacity, increased significantly from pre- to posttest. Both fatigue severity and resting heart rate decreased significantly at posttest. A trend toward improved global QOL was also noted. It was concluded that a 12-week home-based PA intervention may provide health and QOL benefits for prostate cancer patients undergoing ADT. Practitioners are encouraged to promote PA for prostate cancer survivors.     

Construction and validation of a Chinese SRL-based reading instruction questionnaire

The purpose of the study is to construct and validate a Chinese self-regulated learning (SRL)-based reading instruction questionnaire (CSRIQ) and to examine the relationship between Chinese reading instruction and Hong Kong students' reading development from the SRL perspective. A total of 339 Grade 10 students completed the initial CSRIQ in Study 1. Exploratory factor analysis and reliability analyses were used to assess the psychometric quality of the questionnaire, and the original CSRIQ subscales were then revised. Study 2 comprised 1,121 Grade 10 students. The factor structure of the revised CSRIQ was supported by the findings of confirmatory factor analysis. The findings of structural equation modelling indicated significant relations between SRL-based instruction and various reading-related variables. Among the four aspects of instruction, teacher support was the most positive factor facilitating Chinese students' reading development, whereas student autonomy seemed less favourable. Cultural and curricula factors affecting Chinese reading instruction in Hong Kong were discussed.     

Effectiveness and Relevance of Training for International Counseling Graduates: A Qualitative Inquiry

The present study was a qualitative study that sought to examine the experiences and perceptions of international counseling graduates (ICGs) who had returned to their home country to work, focusing on the effectiveness and relevance of the training they had received in the United States. Participants were also asked to outline the roles they played in the development of professional counseling in their own country. Eight themes emerged from in-depth interviews involving nine participants: (a) Pioneering and Leadership, (b) American-centric Training, (c) Sojourner and Returnee Adjustment Distress, (d) Personal Investment from Trainers, (e) Student-Centered Training, (f) Time and Financial Constraints, (g) Independent Learning, and (h) Research. The data indicated that participants’ perceptions of the effectiveness and relevance of their training were mixed. Implications for training international counseling students are considered.     

Construction and Initial Validation of the Chinese Reading Motivation Questionnaire

This paper describes the development and initial validation of a Chinese reading motivation questionnaire (CRMQ) which was designed to assess Chinese students' reading motivation in Hong Kong. The development of the CRMQ consisted of two steps. In the first study, groups of items were constructed based on achievement motivation theories and existing instruments. The initial version of the CRMQ was administered to a small group of Grade 7 students in Hong Kong and exploratory factor analysis, item‐total correlation, and reliability analyses were carried out to assess its psychometric quality. The CRMQ was then revised and administered to a larger sample of Grade 7 students in the second study. Findings of confirmatory factor analysis provided further validation for the proposed factor structure of the revised questionnaire. In addition, findings indicated that students' reading motivation was positively related to their strategy use, reading comprehension, and academic achievement. The findings of this study could enrich our understanding of Chinese reading motivation among Hong Kong students. Implications of these findings for implementing effective reading instruction in Chinese language teaching are also discussed.     

A structural equation modeling investigation of the emotional value of immersive virtual reality in education

Virtual reality (VR) is projected to play an important role in education by increasing student engagement and motivation. However, little is known about the impact and utility of immersive VR for administering e-learning tools, or the underlying mechanisms that impact learners’ emotional processes while learning. This paper explores whether differences exist with regard to using either immersive or desktop VR to administer a virtual science learning simulation. We also investigate how the level of immersion impacts perceived learning outcomes using structural equation modeling. The sample consisted of 104 university students (39 females). Significantly higher scores were obtained on 11 of the 13 variables investigated using the immersive VR version of the simulation, with the largest differences occurring with regard to presence and motivation. Furthermore, we identified a model with two general paths by which immersion in VR impacts perceived learning outcomes. Specifically, we discovered an affective path in which immersion predicted presence and positive emotions, and a cognitive path in which immersion fostered a positive cognitive value of the task in line with the control value theory of achievement emotions.
