Diagonal latent block model for binary data

This paper addresses the problem of co-clustering binary data in the latent block model framework with diagonal constraints for resulting data partitions. We consider the Bernoulli generative mixture model and present three new methods differing in the assumptions made about the degree of homogeneity of diagonal blocks. The proposed models are parsimonious and allow to take into account the structure of a data matrix when reorganizing it into homogeneous diagonal blocks. We derive algorithms for each of the presented models based on the classification expectation-maximization algorithm which maximizes the complete data likelihood. We show that our contribution can outperform other state-of-the-art (co)-clustering methods on synthetic sparse and non-sparse data. We also prove the efficiency of our approach in the context of document clustering, by using real-world benchmark data sets.     

Drinking places: Young people and cultures of alcohol consumption in rural environments

This paper focuses on the contemporary British moral panic about young people and the consumption of alcohol in public space. Most of this public debate has focused on binge drinking in urban areas as a social problem. Here, we consider instead the role of alcohol in rural communities, and in particular alcohol consumption in domestic and informal spaces, as well as the formal drinking landscape of pubs and bars. Drawing on empirical work (including a survey, interviews and participant observation) in rural Cumbria, UK we explore the specific socio-spatial nature of local attitudes to alcohol consumption and its regulation. In doing so, we reflect on the nature of rural lifestyles, community spaces and intergenerational relations. The paper concludes by highlighting some of the implications for health promotion professionals of the generally positive attitude towards young people's drinking in the rural area where the research was conducted. It also draws attention to the need for academics to pay closer attention to the ways that moral panics about binge drinking are implicitly producing a monolithic image of alcohol consumption in urban areas that fails to acknowledge the socio-spatially differentiated nature of practices of alcohol consumption and regulation.     

Factors Motivating Individuals to Take Precautionary Action for an Expected Earthquake in Istanbul

Istanbul is expected to experience an earthquake in the near future, but individuals show limited interest in preparing for it. This study aims to identify the factors associated with taking action to prepare for an earthquake and mitigate its effects at the individual level. A field survey was carried out in 2007 in two districts of Istanbul with different levels of earthquake risk. Within these districts, three socioeconomic levels were considered. A total of 1,123 people were interviewed face to face. Analysis indicated that the educational level of the respondents was the leading factor associated with taking at least three measures, followed by living in a higher earthquake risk area, having participated in rescue and solidarity activities in previous earthquakes, a higher level of knowledge about earthquakes, home ownership, a higher score for action‐stimulating attitudes, being younger, and a higher general safety score, in that order. The findings pointed to the role of knowledge about earthquakes and possible mitigation/preparedness measures, and thus the importance of developing effective awareness programs. Such programs should also consider the characteristics of different groups in the population. Motivated individuals, such as those who have participated in rescue and solidarity activities in previous earthquakes, could be involved in reaching other people.     

Individual and Community Aspects of Women's Status and Fertility in Rural Bangladesh

Samples from the U.S. passenger lists are used to focus upon the emigrants from England to the U.S.A. during 1841. Probably as many as three-quarters of the English emigrants of that year made the U.S.A. their destination, though only a minority of Irish and Scottish emigrants sailed directly to U.S. ports. The English appear very largely to have spurned the unusual opportunities for assisted emigration to colonies that were available that year. The occupations of male emigrants are compared with occupations reported in the population census of 1841. Farmers, general labourers, and industrial workers, particularly those employed in textile industries, were overrepresented among the emigrants. Yet the movement was not predominantly an exodus of labourers from agriculture, nor from some of the most depressed occupations such as framework knitters and nailers. Various occupational groups are analyzed according to travelling companions, dependants and age, in an effort to distinguish between the more cycle-sensitive groups and those seemingly intent on permanent emigration.

Vulnerable children's health as described in investigations of reported children

This study explores whether the social services weigh in health aspects, and what these may be, when investigating reported children's life situation. Information about physical and psychological health aspects for 259 children in 272 investigations was included. Overall, information about children's health was limited. Problematic emotions were the most commonly reported health aspect in the investigations, whereas suicidal thoughts, self‐harm behaviour and gastrointestinal and renal diseases were mentioned least of all. A cluster analysis revealed that the low level of health information group included the largest sample of data and consisted of investigations with minimal information about children's health. The three other cluster groups, Neurological diseases and psychosomatic symptoms, Emotional health and Physical and psychological health and destructive behaviour, consisted of investigations conducted mostly according to the model called Children's Needs In Focus (BBIC, in Swedish, Barns Behov i Centrum). Although these investigations also produced limited information, they provided more than those assessed as having a low level of information about health aspects. The conclusion is that it is necessary to increase information about health aspects in investigations if social welfare systems are to be able to fulfil their ambition of supporting vulnerable children's need of health care.     

Social work Education and Students with Disabilities: Implications of Section 504 and the ADA

Abstract

This article addresses major educational issues related to the Rehabilitation Act of 1973 and the Americans with Disabilities Act of 1990. Because students with disabilities are entering higher education in ever larger numbers, and with greater expectations for accommodation than those of a generation ago, social work educators and administrators should be aware of the implications of these two statutes and relevant case law for admissions, classroom accommodations, and field placements.
