Predictors of Cycling in College Students

Abstract

Objectives: To (1) assess cycling-related questions that have been added to the electronic version of the American College Health Association National College Health Assessment II (ACHA-NCHA), (2) examine cycling prevalence, and (3) identify predictors of cycling in college students. Participants: Predominately female (69%), undergraduate (89%), and white (85%) students (N = 949) from a large, urban, northwestern, bicycle-friendly university completed the electronic version of the ACHA-NCHA II. Methods: Thirty cycling-related questions were added to the ACHA-NCHA II and a subsample of questions was analyzed. Results: Cycling questions added to the ACHA-NCHA II scale were reliable and valid, based on the psychometric data analysis. More than half (59%) of this sample cycled; of those, 58% cycled for transportation and 44% for recreation. Facilitators and barriers to cycling were different for cycling in general and cycling for transportation. Conclusions: Cycling questions added to the ACHA-NCHA II can be utilized to enhance knowledge relative to cycling on college campuses.     

Outcome evaluation of peer support programme for helping Chinese parents under stress

The aim of the study was to evaluate the effectiveness of a support group programme using peer parent counsellors in reducing participant stress and enhancing social support. Participants included 173 Chinese parents with 134 providing complete data. They were randomly assigned to intervention and control groups at service-centre level. The results indicated that there was a significant decrease in psychological distress and increase in social support among intervention group participants at post-intervention, compared with the control group. Qualitative data also indicated that participants' stress was reduced through sharing with their peers. Implications for social service practice were discussed.     

Tabu search for the real-world carpooling problem

Carpooling is a flexible shared transportation system which can effectively reduce the vehicle numbers and fuel consumption. Although many carpooling systems have been proposed, most of them lack practicality, veracity, and efficiency. In this paper, we propose a new useful variant model of the long-term carpooling problem which involves multiple origins and one destination. Such problems commonly occur in a wide number of carpooling situations in real-world scenarios. Our work is motivated by the practical needs to solve environmental pollution, parking problems, traffic jams and low utilization of resources. A Tabu search algorithm is proposed in this paper to solve the carpooling problem. The proposed algorithm aims at a wide range of passenger distribution and routing problems. The computational results based on real world user data show the effectiveness of the proposed algorithm. Moreover, we developed a mobile application based on our carpooling model.     

Managing Integrity: The Regulation of Post Public Employment in Britain and Hong Kong

In this article, we examine the regulatory mechanisms governing post public employment in Britain and Hong Kong in the context of changing views on how integrity should be managed in their civil services. In both places, new public management practices have increased the possibility of ‘soft’ conflicts of interest which in turn has resulted in debates over the necessary degree of regulation, the organizational form that this should take, and the extent to which ethical concerns should be more focused on the communication and inculcation of core values in civil servants. We argue that the difficulty of regulating ‘soft’ conflicts of interests is driving moves toward the greater centralisation of ethical regulation in both Britain and Hong Kong and that there appears to be a return to more traditional ways of managing integrity.

Classification of dichotomous and continuous variables with incomplete samples

This Article Considers the problem of classifiying an observation consisting of both binary and continuous variables based on two general incomplete training samples one from each of the two given populations. The location linear model adopted by krzanowski 1975 forms the basis of our inverstigation. For a given location, When the common dispersion matrix as Well as the corresponding cell probabilities for the underlying populations are known, exact distribution of the conditional maximum likelihood classification rule is derived. The overall error rate can be obtained and is based on linear cominations of independent non– Chi– Distributions. large sample result for the case where the cell probabilities are unknown is also available.     

Social Mitigation of the Impact of Urban Renewal on Residents’ Morale

Residents in the site of urban renewal suffer from its disturbance particularly during its demolition phase. One possible way of mitigating the suffering is assistance from kin and neighbors. The possibility rests on need fulfillment theory, which posits that needed assistance is salutary. To examine this possibility, the study surveyed 437 residents staying around urban renewal sites in Hong Kong. Results lent support to the hypothesized mitigation regarding neighbors’ help but not kin’s help. Instead, the kin’s support exhibited a significantly main positive effect on a resident’s morale. Furthermore, quality in neighborhood amenities but not in the residential environment showed a significantly main effect on morale. Results imply the merit of sustaining amenities quality and kin and neighbor assistance for mitigating the demoralizing impacts on residents during urban renewal.     

Romantic Relationships,Relationship Styles,Coping Strategies,and Psychological Distress among Chinese and Australian Young Adults

This study examined the association between relationship styles, coping strategies, and psychological distress among 144 Anglo‐Australian and 250 Hong Kong Chinese undergraduate students. The results indicated that relationship styles (secure, clingy, and fickle) influenced psychological distress through their association with coping strategies (avoidance and self‐punishment). Society of residence was a moderating factor for the association between clingy relationship style and psychological distress. Females also reported higher levels of psychological distress than males. Among participants who had experienced a romantic relationship break up, participants endorsing clingy relationship style and those whose partners initiated the break up expressed more hurt in comparison, whereas those who endorsed avoidance strategy reported less hurt. The results of the present study also suggested that psychosocial variables (relationship styles, coping strategies) were generally more important than demographic factors (e.g., age) in predicting mental health outcomes. However, relationship styles and coping strategies may operate differently under different contexts.     

An Integrated Decision Methodology for Designing and Operating an Air‐Express Courier's Distribution Network*

DHL, an international air‐express courier, has been operating in Hong Kong for many years. In 1998, the new international airport located at a site considerably distant from the old location opened in Hong Kong (HK). Other airport‐related infrastructure facilities have also been developed or are being developed, resulting in major changes in transport structure as well as a shift in customer demand. In this paper a multiyear distribution network is designed for DHL(HK) using an integrated network design methodology, which consists of a macro model and a micro model. The macro model, a mixed 0–1 LP, determines in an aggregate manner the least‐cost distribution network. The micro model, a simulation, evaluates the operational viability and efficacy of the network according to its service coverage and service reliability. We also illustrate how coverage and reliability can be improved via the integrated use of the two models. Extensive discussion on relevant planning and operational issues of an air‐express courier are included. The methodology has been successfully implemented at DHL(HK). It has been used to design the network, to test strategic decisions, and to update the network.     

Social Networks and Self Enhancement in Chinese Children: A Comparison of Self Reports and Peer Reports of Group Membership*

Children's self reports of social groups were compared with the social groups identified by a consensus judgment of their peers. The subjects were 138 Chinese 4th grade students (mean age = 9.91) from a primary school and 167 Chinese 7th grade students (mean age = 13.09) from a secondary school, both located in Hong Kong. Following the Social Cognitive Map (SCM) procedure, students were asked to identify the social groups within their grades, including their own groups. The subjects also rated themselves on multiple domains of competence. Their teachers rated them on the same domains. Subjects tended to be biased toward self-enhancement when reporting their own groups: They omitted members who had low school scholastic rank and unfavorable scores on teacher ratings of competence. There was a strong effect of propinquity and gender on group membership, in that all groups were comprised of children from the same classroom and virtually all (98%) of the same sex. Members scored similarly on teacher ratings of competence. In elementary school, conventional values and academic achievement provided the behavioral bases for peer group cohesion. By early adolescence, peer-related concerns supplemented rather than replaced conventional values as the bases for group cohesion.
