Identifying long-run behaviour with non-stationary data

Copyright @ 2000 Université Catholique de LouvainResults for the identification of non-linear models are used to support the traditional form of the order condition by sufficient conditions. The sufficient conditions reveal a two step procedure for firstly checking generic identification and then testing identifiability. This approach can be extended to sub-blocks of the system and it generalizes to non-linear restrictions. The procedure is applied to an empirical model of the exchange rate, which is identified by diagonalising the system

Current trends in the use of residential child care in Scotland

The survey was planned to examine how local authority residential care units were currently being used and to provide data relating to current issues in the use of residential child care. These issues were identified by Scottish Institute for Residential Child Care (SIRCC) staff as they provided training and development work with agencies across Scotland, and others have been part of wider professional and political concerns. They include matters such as the increasing numbers of children being admitted to care because of parentaldrug misuse. There is also anecdotal evidence about increasing numbers of seriously disturbed younger children having to be admitted to residential care because their difficulties preclude them being cared for in a foster home placement, or who had experienced a number of foster placement breakdowns. SIRCC provides a ‘Placement Information Service’ and over the past few years there has been a steady stream of enquiries from social workers looking for a ‘therapeutic placement’ for a younger child. There were also reports of sibling groups still being regularly split up on admission due to lack of places and a general reporting of a shortage of places. Noteworthy also has been the continued high level of emergency placements. As there has been a gradual reduction in residential places over the past 10 to15 years and as residential care is perceived to be an expensive resource it is important to understand what kinds of admissions are putting such pressure on existing resources. The survey therefore requested information about a wide range of topics related to admission to residential care including: age at admission length of stay; previous placement; whether placement was planned or not;whether siblings groups were kept together or not; whether the child was in full-time education or not; the reasons for admission including parental drug misuse; whether the placement was the placement of choice of the socialworker or residential services manager. The survey also asked respondents to give a broad measure of the effectiveness of the placement. It was hoped that the data might supplement the Looked After Children (LAC) statistics that are published annually by the Scottish Executive (SE), based onreturns from local authorities

Evaluation of fostering network Scottish care mentoring projects

Looked after children and young people are some of the most vulnerable in our society. For Scotland’s Children highlighted the ‘continuing failure of many local authorities as ‘corporate parents’ to provide these young people with the care and education they are entitled to by law’ (Scottish Executive, 2001, p. 10). One of the major issues facing looked after young people is the process of transition from care to independence. It is a time when they have ‘a right to expect the sort of help that loving parents would provide for their children, help to reach their full potential, and the same chance to make mistakes secure in the knowledge that there is a safety net of support’ (Jamieson, 2002, p. 2). However, over a number of years, research has highlighted the poor outcomes for children leaving care. Longitudinal studies which have followed up children and young people in care as part of national cohort studies present the stark contrast in life outcomes between those who have experienced care and those who have not. Cheung and Heath (1994) compare these two groups at age 33. Only one fifth of those who had been in care had achieved O levels compared to one-third of those who had not; only half as many had achieved A levels. Only one in a hundred of those who had been in care achieved a university degree compared to one on ten of those who had not. Two fifths of those who had been in care had no formal qualifications compared to one in seven (Cheung and Heath, 1994). This lack of qualifications converted into lack of success in the job market with three times as many being unemployed (10.8 % compared to 3.6 %) and larger proportions having manual jobs as opposed to professional or non-manual jobs

Bose-Einstein Condensates as a Probe for Lorentz Violation

The effects of small Lorentz-violating terms on Bose-Einstein condensates are analyzed. We find that there are changes to the phase and shape of the ground-state wave function that vary with the orientation of the trap. In addition, spin-couplings can act as a source for spontaneous symmetry breaking in ferromagnetic condensates making them sensitive probes for fundamental symmetry violation
