Decision support system for the batching problems of steelmaking and continuous-casting production

This paper investigates two batching problems for steelmaking and continuous-casting (SCC) production in an integrated iron and steel enterprise. The tasks of the problems are to make the decisions as how to consolidate ordered slabs into charges, and then how to group charges into casts. The effective decisions on these batching problems can help to balance the requirements of materials in downstream production lines, improve the customer satisfaction levels, and reduce production costs (including reduction of open ordered slabs, less slabs quality upgrading, reduction of steel-grade changeovers, and reduction of inefficient utilization of tundishes lives). We first formulate the problems as integer-programming models by consider practical constraints and requirements, and then develop the two heuristic algorithms for the corresponding batching problems. By embedding above models and algorithms, we develop decision support system (DSS) software with interactive planning editor. The DSS has been tested by using practical data set collected from the steelmaking plant in Baosteel which is one of the most advanced iron and steel enterprises in China. Computational experiments demonstrate that the models and algorithms developed can generate the satisfactory solutions when they work together with the planning editor in the DSS.     

Firm-level correlates of emergent green supply chain management practices in the Chinese context

Greening the supply chain is increasingly a concern for many business enterprises and a challenge for logistics management in the 21st century. Of particular concern is how to arouse organizational environmental awareness and put environmental activities into practice in the logistics activities of their supply chains. This paper investigates the correlation of two major factors, organizational learning and management support, with the extent of adoption of green supply chain management (GSCM) practices in Chinese manufacturing firms, where their inbound and outbound logistics activities are potential polluters to the environment. Organizational and operational learning was derived from the firm's experience with programs such as total quality management and environmental management systems. Management support included support for GSCM ideas and practices from top and middle-level management and cooperation across organizational functions. We find significant positive relationships between organizational learning mechanisms, organizational support and the adoption of GSCM practices, after controlling for a number of other influences including regulations, marketing, supplier, cost pressures, industry levels of the relevant practice and organizational size. Implications of our findings on logistics management are discussed.     

Income support for Australian carers since 1983: social justice,social investment and the cloak of gender neutrality

Income support for carers has been available in Australia since the early 1980s. In contrast to most other forms of income support, eligibility for Carer Payment has been progressively expanded in recent years, and increasing numbers of carers are claiming the payment as a result. This article examines the history of income support for carers by reviewing changes in eligibility criteria in the social security legislation and considering how those changes were framed. We argue that reforms to carers' income support have developed within competing frames of social justice and social investment, with an increasing emphasis on a social investment discourse, which prioritises paid work over care. Neither of the dominant frames addresses gender equality, and in practice, income support policy has reinforced familial (women's) responsibility for caring. Given the gendered nature of caring in Australia, gender equality issues must be considered in future policy reforms to ensure that the competing pressures on women to care and to engage in paid work do not lead to greater disadvantage and inequality for women and the people for whom they care.

Families with young children in times of economic downturn: Implications for social work practice

In response to the global financial crisis, social policies in Europe and elsewhere incorporated a logic of social investment to reduce (child) poverty and social inequality. Several critiques, however, have been raised against the narrowness of this discourse. In order to introduce another way of seeing, an interview study was conducted inspired by the interpretative paradigm of lifeworld orientation. This has allowed us to acquire a critical, in‐depth understanding of the consequences of economic downturn and unemployment for families with young children (0–3 years old), from their point of view. Findings highlight the importance of listening to parents here and now, in order to be able to take account of their concrete, lived realities within the context of the broader society and critically assess these realities according to principles of human dignity and social justice. Implications for social work practice are discussed.     

Kernel partial correlation: a novel approach to capturing conditional independence in graphical models for noisy data

Graphical models capture the conditional independence structure among random variables via existence of edges among vertices. One way of inferring a graph is to identify zero partial correlation coefficients, which is an effective way of finding conditional independence under a multivariate Gaussian setting. For more general settings, we propose kernel partial correlation which extends partial correlation with a combination of two kernel methods. First, a nonparametric function estimation is employed to remove effects from other variables, and then the dependence between remaining random components is assessed through a nonparametric association measure. The proposed approach is not only flexible but also robust under high levels of noise owing to the robustness of the nonparametric approaches.     

A Support Group for Caregivers of Children with Craniofacial Differences

ABSTRACT

Caregivers of children with craniofacial differences (CFD) experience psychosocial stressors; however, few groups are described for this population. The authors outline an eight-session group and qualitative analysis of caregivers’ experiences. The majority of participants (n = 100) were mothers (76%) of children who were female (75%) and identified as Latino (79%). Children’s mean age was 10.6 (SD = 2.8) years, and they were born with cleft lip/palate (56%) along with other CFD diagnoses. Themes included: group appreciation (21%), mutual acceptance (18%), coping (18%), parenting skills (17%), learning (9%), resiliency (7%), empathy (4%), diagnosis information (3%), and self-care (3%). Caregivers’ reported experiences largely corresponded with group goals.     

Educational inequality across three generations in Australia

The transfer of advantage and disadvantage across multiple generations is receiving increasing attention in the international literature; however, transfers of resources across multiple generations in Australian families are less well understood. Using a longitudinal dataset of Australian children, we have the opportunity to not only investigate the transfer of educational resources across three generations in Australia, but also investigate the gendered nature of these transfers, which has been a limitation of other studies. We find no evidence of individual grandparent education effects on numeracy and reading scores for grandchildren in Year 3, independent of parent educational attainment and other covariates. However, significant effects on numeracy and reading scores were observed for children in families where both the grandmother and grandfather in maternal and paternal grandparent sets had high educational attainment (a diploma or university qualification), and where either or both the mother and father had a university qualification. These results suggest that the contribution of grandparents to the academic achievement of grandchildren cannot be fully explained by the parent generation and that the concentration of human capital in families contributes to educational inequalities across multiple generations that can be observed by eight years of age.     

Absent Role of the State: Analysis of Social Support to Older People with Disabilities in Rural China

China is experiencing rapid population ageing and already has 44 million older people with disabilities aged over 59 years. Yet social support of these older people with disabilities is undeveloped and not well researched. This article contributes by using a disability rights framework (right to life and protection, economic security and social support) to analyze local cases in rural China. It finds that, although the family is still the main provider of economic and care support to rural older people with disabilities, the absence of a state role in welfare provision has negative impacts on the well‐being of older and younger generations in rural families.     

Health and community services for trafficked women: an exploratory study of policy and practice

The trafficking of women has attracted considerable international and national policy attention, particularly since the UN Protocol to Prevent, Suppress and Punish Trafficking in Persons, Especially Women and Children (2000), of which the Australian Government has been a signatory since 2005. The provision of health and community services for trafficked women is a central feature of this Protocol, but in Australia service provision is made difficult by how trafficked women are understood and treated in policy and legal terms. This study aimed to explore the provision of health and community services for trafficked women in the Greater Sydney region through a series of interviews with government and non‐government organisations. The findings reveal that services have been inaccessible as a result of sparse, uncoordinated, and poorly funded provision. The major obstacle to adequate and appropriate service provision has been a national policy approach focusing on ‘border protection’ and criminalisation rather than on trafficked women and their human rights. We conclude that further policy development needs to focus on the practical implications of how such rights can be translated into the delivery of health and community services that trafficked women can access and be supported by more effectively.
