Strategies Used by Gay and Bisexual Young Men to Cope With Heterosexism

ABSTRACT

Although the pervasiveness of heterosexism in the lives of gay and bisexual youth is well established, little is known about the strategies these youth use to cope with stigma and discrimination based on their sexual minority status. In this qualitative study, the authors present findings and implications for clinical practice based on interviews with 43 gay and bisexual young men. Respondents’ coping strategies are discussed in relation to current theory and research on coping with stigma, as well as the emerging field of emotion regulation. The narratives from the current study suggest that the emotion regulation paradigm is well suited to understanding the functions of strategies for coping with heterosexism and similar types of stigma.     

Executive functioning in Asian pathological gamblers

Two decades of neuropsychological research on predominantly Caucasian problem gamblers has unveiled significantly poorer performance on several domains of executive functioning (EF) relative to healthy controls. However, contradictory findings are widespread and evidence that pathological gamblers (PGs) are ‘impaired’ remains inconclusive. The study examined multiple facets of EF in 30 male, PGs seeking outpatient treatment in Singapore and 30 matched controls. CANTAB® tests of planning and organization/problem-solving, set-shifting, working memory and reflection impulsivity, were administered alongside the Barratt Impulsiveness Scale, Cognitive Failures Questionnaire and Dysexecutive Questionnaire. No significant group differences were found on any of the EF performance parameters, with performance falling in the healthy, unimpaired range for both groups. PGs did, however, report significantly greater impulsivity, everyday cognitive failures and symptoms of the dysexecutive syndrome. Exploratory analysis on a subgroup of PGs addicted to non-strategic gambling activities revealed poorer EF performance than among those addicted to strategic gambling activities. The findings suggest an absence of EF deficits despite higher trait impulsivity in Asian, predominantly strategic PGs. Hence, psychological interventions such as CBT and treatment approaches that emphasize the use of self-monitoring and informed decision-making to reduce impulsive behaviours should be suited to this population.     

Development and validation of the Chinese adolescent gambling expectancy scale

Gambling expectancies have been reported to be an important variable in adolescents' gambling behaviours. However, little is known regarding the role of gambling expectancies among Chinese adolescents. This study aimed to identify Chinese adolescents' expectancies for gambling and to evaluate their relation to gambling behaviours. Exploratory and confirmatory factor analyses were performed which confirmed that a five-factor model was a good fit for the data. The five factors – namely, social benefits, relational costs, material gain, being out of control, and money loss – were revealed. The findings demonstrate the importance of understanding gambling behaviours within specific cultural contexts.     

Perpetuating Old Exclusions and Producing New Ones: Digital Exclusion in an Information Society

This article presents a study that measures the degree of digital exclusion—or, conversely, the degree of digital inclusion—in Hong Kong, a developed city in East Asia. Governments in the region are among the most active in the developed world in pushing ahead in developing knowledge economies and information societies. The major concern is to improve/maintain their competitiveness in the new knowledge economy created by the process of globalization and the advancement in information technology. Many countries in the region have established themselves in the top ranks of a number of indexes and measurements comparing digital readiness, digital access, information and communication technology penetration, and others. However, not all the citizens in the region share the benefits and promises of the information society. People who are traditionally disadvantaged, such as the elderly and those on a low income, are further excluded from the information society. Such exclusion affects other social groups as well. This study creates a new digital inclusion index to measures the degree of inclusion of various disadvantaged groups in an information society. Data regarding seven disadvantaged groups were collected through a household survey (N = 2,312). The index captures information about access, knowledge, usage, and affordability ininformation and communication technology of the disadvantaged in comparison with mainstream society (N = 284).     

Adaptive grid semidefinite programming for finding optimal designs

We find optimal designs for linear models using a novel algorithm that iteratively combines a semidefinite programming (SDP) approach with adaptive grid techniques. The proposed algorithm is also adapted to find locally optimal designs for nonlinear models. The search space is first discretized, and SDP is applied to find the optimal design based on the initial grid. The points in the next grid set are points that maximize the dispersion function of the SDP-generated optimal design using nonlinear programming. The procedure is repeated until a user-specified stopping rule is reached. The proposed algorithm is broadly applicable, and we demonstrate its flexibility using (i) models with one or more variables and (ii) differentiable design criteria, such as A-, D-optimality, and non-differentiable criterion like E-optimality, including the mathematically more challenging case when the minimum eigenvalue of the information matrix of the optimal design has geometric multiplicity larger than 1. Our algorithm is computationally efficient because it is based on mathematical programming tools and so optimality is assured at each stage; it also exploits the convexity of the problems whenever possible. Using several linear and nonlinear models with one or more factors, we show the proposed algorithm can efficiently find optimal designs.     

Efficient Heuristics for Orientation Metric and Euclidean Steiner Tree Problems

We consider Steiner minimum trees (SMT) in the plane, where only orientations with angle , 0 i – 1 and an integer, are allowed. The orientations define a metric, called the orientation metric, , in a natural way. In particular, ₂ metric is the rectilinear metric and the Euclidean metric can beregarded as metric. In this paper, we provide a method to find an optimal SMT for 3 or 4 points by analyzing the topology of SMT's in great details. Utilizing these results and based on the idea of loop detection first proposed in Chao and Hsu, IEEE Trans. CAD, vol. 13, no. 3, pp. 303–309, 1994, we further develop an O(n²) time heuristic for the general SMT problem, including the Euclidean metric. Experiments performed on publicly available benchmark data for 12 different metrics, plus the Euclidean metric, demonstrate the efficiency of our algorithms and the quality of our results.     

The Impacts of Acculturative Stress and Social Competence on the Mental Health of Mainland Chinese Immigrant Youth in Hong Kong

Correspondence to Dr Daniel Fu Keung Wong, Associate Professor in the Department of Social Work and Social Adminstration, 1317 K K Leung Building, The University of Hong Kong, Pokfulam Road, Hong Kong.E-mail: dfkwong{at}hkucc.hku.hk Summary Attempts were made to examine migration stressors, social competence,and mental health status of immigrant youth in Hong Kong andto examine the effects of social competence on stress and themental health of immigrant youth. Data on 106 immigrant youth,which were collected through a structured questionnaire, wereanalysed. It was discovered that immigrant youth found survivalissues and losses, rather than cultural differences and unfulfilledexpectations, to be stressful. Male immigrant youth exhibitedmore psychological distress symptoms than female immigrant youth.Hierarchical regression analyses revealed that social competenceexerted moderating effects on stress and the mental health ofimmigrant youth. Immigrant youth who had a higher level of socialcompetence, in terms of self-control, empathy, assertivenessand the ability to read social cues, had less stress and enjoyedbetter mental health. In conclusion, personal and socio-culturalreasons are put forward to explain the findings. Practice andpolicy implications are also discussed.

Vehicle routing using fixed delivery areas

In this paper we consider the problem of vehicle routing using fixed delivery areas. This is the problem of splitting the area serviced by a depot into a number of separate subareas—a single delivery vehicle being assigned to each subarea to supply all the customers within the subarea. A heuristic algorithm is developed for the problem based upon an initial allocation of customers to subareas followed by customer interchanges in an attempt to improve the subareas. Computational results are presented for a number of test problems drawn from the literature.
