Sociometric methods and difference: a force for good – or yet more harm

This paper offers a critique of sociometrics as a ubiquitous method of measuring social relationships among children in social groups such as school classes. This is important in relation to disability politics and research as the apparently scientific measures are frequently used in the process of labelling children or predisposing the children involved, or others involved with them, to view disabled and other children in particular ways. We open a debate about judgements concerning whether the use of sociometric techniques needs to be better informed by questions about the underpinning normalising frameworks on which they depend, about the connotations of blame associated with particular sociometric statuses, and about the way that research constructs difficulties and reflects an adult agenda, marginalising the voices of (disabled) children. We argue for the value of the transactional turn in understanding the implications of this approach and for highlighting alternative perspectives.     

Immigration Controls,Life-Course Coordination,and Livelihood Strategies: A Study of Families Living across the Mainland-Hong Kong Border

In-depth studies of families living across the mainland Chinese-Hong Kong border indicate how immigration controls can adversely affect the ability of families to synchronize members’ life-courses to provide for their own livelihoods. By disrupting family timetables, the immigration quota system that governs migration from the mainland to Hong Kong hampers the attempts of families to secure their long-term viability and arrange for inter-generational caring. Circumventing immigration laws through illegal migration is costly, and family care-givers are often forced to stay in Hong Kong without being recognized as residents. Mainland-Hong Kong families have a unique opportunity to live on one side of the border while members commute to work or study on the other side, but this strategy affects long-term social participation and is available only to families with the requisite social and economic assets. The research was supported by a grant from Oxfam Hong Kong. The Hong Kong Catholic Commission for Justice and Peace, Hong Kong Christian Action, the Industrial Relations Institute, and St. James’ Settlement made the interviews possible by helping us contact our informants. Caren Wong, Lo Kwok Wai, and Lai Yuen Mei provided competent research assistance. Chan Chu Fung was a tremendous help in our research on public policies. We must also thank our informants for agreeing to be interviewed and sharing with us personal information about their life.     

Long‐term Outcomes for Children with Early Language Problems: Beating the Odds

Using the 1970 British Cohort Study, this study examines factors promoting positive language development and subsequent successful education and employment transitions among children showing early receptive language problems (age 5). We find that 61 per cent of children with early receptive language problems develop into competent readers by age 10. Factors promoting positive language development include parental support and more importantly a good school environment, characterised by only few children receiving remedial help. Post‐16 education and employment experiences indicated competent reading to be associated with a less challenging journey into adulthood. Findings are discussed in terms of their policy implications.     

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.     

A hybrid algorithm based on variable neighbourhood for the strip packing problem

This paper addresses the strip packing problem, which has a wide range of real-world applications. Our proposed algorithm is a hybrid metaheuristic that combines an improved heuristic algorithm with a variable neighbourhood search. Different neighbourhoods are constructed based on the concept of block patterns. The proposed algorithm has three interesting features. First, a least-waste strategy is used to improve the constructive heuristics. Second, a better sorting sequence is selected to generate an initial solution. Finally, different neighbourhoods are constructed based on block patterns. The computational results from a diverse set of problem instances show that the proposed algorithm performs better than algorithms reported in the literature for most of the problem sets compared.     

A Lean transportation approach for improving emergency medical operations

Abstract

This paper extends the approach of Lean transportation to improve the performance of emergency medical processes (EMP) by adapting its main concepts into the main characteristics of the EMP environment. The paper is based on an inductive theory-building process initiated from a case study in the field of emergency medical services. The development of the suggested performance improvement approach triggered from an exhaustive analysis of a process involved and an exploratory review of the existing improvement approaches available. The process of concern can be described as a specialized transportation process, where human lives are at risk. Its characteristics led to a natural application of Lean transportation. The results include, a novel approach for improving the agility and efficient EMS processes. This is validated with an application for improving ambulance response times and turnaround times of the Red Cross operations located in Monterrey, Mexico. The approach proved to be an integrated scheme for identifying waste opportunities at a systems level. This characteristic is important to let operations management prioritize improvement efforts in a limited budget situation. This work suggests the application of the emerging Lean transportation approach for increasing the agility performance of EMS processes.     

Smoothing Spline Estimation for Partially Linear Single-index Models

In this article, the partially linear single-index models are discussed based on smoothing spline and average derivative estimation method. This proposed technique consists of two stages: one is to estimate the vector parameter in the linear part using the smoothing cubic spline method, simultaneously, obtaining the estimator of unknown single-index function; the other is to estimate the single-index coefficients in the single-index part by the using average derivative estimator procedure. Some simulated and real examples are presented to illustrate the performance of this method.     

The Emergence of a Community-based Social Assistance Programme in Urban China

To many people, the problem of poverty in China was confined mainly to the rural areas, and the situation of urban poverty was regarded as insignificant. Yet in fact, market-orientated economic reforms have created an urban underclass, made up of poorly paid state workers, the unemployed, and migrants from the countryside. In attempting to respond to the mounting needs of the urban poor, the Chinese government has introduced a means-tested social assistance programme in the cities since the mid-1990s. This paper describes the basic philosophy, structure and operation of this programme, and provides a general assessment of its functions and shortcomings.     

Sustainable Social Work: An Environmental Justice Framework for Social Work Education

Environmental degradation is not experienced by all populations equally; hazardous and toxic waste sites, resource contamination (e.g., exposure to pesticides), air pollution, and numerous other forms of environmental degradation disproportionately affect low income and minority communities. The communities most affected by environmental injustices are often the same communities where social workers are entrenched in service provision at the individual, family, and community level. In this article, we use a global social work paradigm to describe practical ways in which environmental justice content can be infused in the training and education of social workers across contexts in order to prepare professionals with the skills to respond to ever-increasing global environmental degradation. We discuss ways for social work educators to integrate and frame environmental concerns and their consequences for vulnerable populations using existing social work models and perspectives to improve the social work profession's ability to respond to environmental injustices. There are significant social work implications; social workers need to adapt and respond to contexts that shape our practice, including environmental concerns that impact the vulnerable and oppressed populations that we serve.
