The Ties that Bind: Support from Birth Families and Substitute Families for Young People Leaving Care

This paper draws on findings from a study of outcomes for youngpeople leaving care funded by the Department for Education andSkills. It explores the informal support networks availableto a sample of 106 young people over a period of 12–15months after leaving care. It examines patterns of contact withbirth families and caregivers, the support that emanated fromthese links and the strategies of leaving care professionalsto strengthen these connections. It also considers the new familiescreated by many young people through relationships with partnersand the onset of parenthood and discusses the continuing supportneeds of young parents. The paper situates the needs and experiencesof care leavers in a wider youth transitions framework and highlightsthe need for continuing professional attention to be given tostrengthening family links as one strategy for helping careleavers to negotiate the transition to adulthood.     

The Impact of Political Conflict on Social Work: Experiences from Northern Ireland, Israel and Palestine

This paper investigates the impact of violent political conflicton social workers and service users in three countries: NorthernIreland, Israel and Palestine. Despite its significance forsocial work (and other helping professions), there is a dearthof research on the subject. The authors construct a researchframework which encapsulates the complexity and ambiguity ofthe issues at stake and three parallel empirical studies, whichfollow this framework, are presented. The findings highlightthe burden of working and living in a violent political conflict,not just for service users but also for social workers. Emotionalstress, fear, competing national and religious identities, yetsome indication of resilience, are key findings from these studies.A number of moral and professional dilemmas emerged across allthree studies, often testing loyalty to universal social workvalues. Thus, some respondents at times found it difficult todeal with colleagues and service users who were perceived tobe ‘the enemy’. These studies highlight the needto raise the consciousness of social workers, agencies and policiesabout such issues in a world which is increasingly afflictedby violent political conflict. Support, education and trainingfor social workers which transcend national contexts and furtherinternational research in this important area are recommended.     

Wavelets

Wavelets have aroused much interest and offer advantages in signal and image processing. Wavelets and also the wavelet transform are defined here. Their use as a vehicle for multi-resolution image analysis is discussed in the cases of one and two dimensions, and the decomposition-reconstruction algorithm is described. Some simple examples are presented to illustrate the ideas, and several applications are described. Some ideas for further reading are given.     

Post-high school choices: New evidence from a multinomial logit model

A multinomial logit model is estimated to investigate the destination of students one-year after graduating from high school. The appropriate specification of the choice set available to high school leavers is as follows: private four-year college, public four-year college, private two-year college, public two-year college, employed and unemployed. We test for several possible combinations of these choices and find that these pooled models are all rejected in favour of the full model. The transition from high school to college and to work is more complex than previous studies have recognised. Received: 12 July 2002/Accepted: 2 November 2002 All correspondence to Jim Taylor.

Physical and chemical properties of a Hong Kong roadside soil in relation to urban tree growth

Tree planting in urban areas faces many limitations that suppress performance and increase management burdens. Soil problems are increasingly recognized as an important cause of establishment failures and declines. Recent city-greening programs in Hong Kong necessitate a better understanding of soil difficulties, but relevant information is lacking. A detailed study of physical and chemical properties of a representative roadside soil provides baseline data on edaphic restrictions and hints for correction and amelioration. The soil depth is inadequate for normal root expansion of trees, is excessively stony and sandy, and is beset by poor structure and heavy compaction. Root growth is likely to be restricted by the low levels of porosity and high shear strength. The densely packed surface layer reduces aeration and water movement into the lower layers. The nutrient stock is meager, and the ability to hold available moisture and nutrients is very limited. Soil reaction comparing with local natural soil is uncharacteristically alkaline with pH reaching 8.5 which may induce iron and manganese deficiency. Heavy metals register elevated concentrations especially for lead and zinc, but do not attain phytotoxic levels. The common multiple substrate problems need to be addressed properly before trees are planted. Evaluation of selected soil attributes is advocated for all planting sites.     

An Examination of the Use of Coercion by Assertive Outreach and Community Mental Health Teams in Northern Ireland

In mental health services over recent decades, the positivemove away from hospital-based care to community-based serviceshas entailed that people with higher levels of need are beingsupported by community mental health services. This paper beginsby reviewing the literature on coercion in the field of community-basedmental health care and treatment. It is argued that the lackof a critical understanding of the concept and how it is usedby practitioners and agencies can have serious repercussionsfor the rights of service users. Using a quasi-experimental,longitudinal design, the authors then seek to test some of theideas about coercion by comparing the activities of assertiveoutreach and community mental health teams in Northern Ireland,particularly the key ideas of perceived coercion, workers’strategies and engagement with services. Key findings were thatassertive outreach appeared to be more successful at reducingperceived coercion, minimizing the need for coercive strategies,engaging high-risk clients and reducing inpatient bed use. Thesefindings are compared with other studies in this area. The authorsalso argue that there is a need for greater transparency inthe way that practitioners use coercive measures and more explicitguidance is required in this crucial area of mental health practice.     

What Parents Think About Child Rearing!

In a survey of current attitudes of parents towards child rearing, 386 parents of 4th grade children completed questionnaires containing Hereford's Parent Attitude Scale. Results indicated that parents with the highest education and occupational status were: more confident in themselves as parents; more inclined to believe that they could influence their child's behaviour; more accepting of the child as an individual; shared ideas and feelings more often with their child; and were more likely to enjoy a mutually trusting relationship with their child. This suggests that programmes aimed at improving parent-child relationships should be primarily directed towards the less well educated and those of lower occupational standing. Yet the Health Commission, in pilot Parent Effectiveness Training (PET) programmes found that parents who joined the programmes were even better educated than those in the survey, and already had very favourable attitudes towards child rearing.     

The Lovász Extension of Market Games

The multilinear extension of a cooperative game was introduced by Owen in 1972. In this contribution we study the Lovász extension for cooperative games by using the marginal worth vectors and the dividends. First, we prove a formula for the marginal worth vectors with respect to compatible orderings. Next, we consider the direct market generated by a game. This model of utility function, proposed by Shapley and Shubik in 1969, is the concave biconjugate extension of the game. Then we obtain the following characterization: The utility function of a market game is the Lovász extension of the game if and only if the market game is supermodular. Finally, we present some preliminary problems about the relationship between cooperative games and combinatorial optimization.     

Bitter strawberries: the construction of differences in a multicultural school: a case study

This paper presents the results of a case study looking at the views of teachers and other educational professionals pertaining to the academic progress and general integration of immigrant schoolchildren in multicultural schools in the province of Huelva (Andalusia, Spain). It is organised into three sections: first, the geographical and social context of the study is described, focusing in particular on the impact on schools of migratory trends within the province associated with strawberry cultivation. This is followed by a presentation of the results of a field study into the educational panorama of immigrant pupils from various countries, drawing on verbal reports by teachers and school administrators. Finally, some conclusions are suggested for possible categories of analysis with a view to opening new lines of research in the future.
