This paper presents the results of an independent evaluation of the Multi-dimensional Treatment Foster Care (MTFC) programme for young offenders in England, where it is known as Intensive Fostering (IF).

Methods

A quasi-experimental, mixed methods study was carried out at the three pilot sites, with a total sample of 47 at follow up. Young people sentenced to IF were compared to a similar group, matched on the eligibility criteria for IF, the majority of whom were sentenced to custody. The groups were well-matched in terms of their characteristics and criminal histories. Official data on reconviction were collected at baseline and one year after entry to the IF placement or release from custody (Stage 1), and further data on programme completion and secondary outcomes were collected via interviews with young people and parents and questionnaires to professionals at baseline and follow up. Official data on reconviction were also collected one year after exit from the IF placements (Stage 2).

Results

At Stage 1 the IF group were less likely to be reconvicted, had committed fewer and less serious recorded offences, on average, and took longer to commit their first recorded offence. At this point the IF group were more likely to be living with their families and less likely to be in custody than the comparison group. However by Stage 2 no significant differences in patterns of reconviction remained.

Conclusions

IF successfully contained a high-risk group in the community, but the effects of the intervention washed out once they left their foster placements. Environmental effects on entry to and exit from the IF placements may help to explain the results at both stages.  相似文献

This multi-faceted study assessed the differences between accessible and central child protection service delivery sites in Ontario on: (1) family functioning; (2) front-line child protection service providers' satisfaction with services; (3) parents' satisfaction with services; (4) the services and supports available to families; (5) front-line service job satisfaction; and (6) front-line helping relationships in child welfare. A quasi-experimental outcome design gathered data from parents at case-opening and approximately 10 months later. Semi-structured individual or group qualitative interviews were conducted with parents, front-line service providers, and supervisors/managers. Information also was gathered from agency files. Front-line service providers completed an employment questionnaire. Findings indicated that the accessible sites were able to foster a greater proportion of cooperative helping relationships with families and to create more service partnerships. Parents at the accessible sites were more positive about their service involvements and more willing to ask for help again in the future. Front-line child protection service providers at both service delivery models described positive aspects of their jobs as well as frustrations with the expectations of the formal child protection system.  相似文献

The private security industry is often represented - and typically represents itself - as an expanding business, confident of its place in the world and sure of its ability to meet a rising demand for security. But closer inspection of the ways in which industry players talk about its past, present and future suggests that this self-promotion is accompanied by unease about the industry's condition and legitimacy. In this paper, we analyse the self-understandings of those who sell security - as revealed in interviews conducted with key industry players and in a range of trade materials - in order to highlight and dissect the constitutive elements of this ambivalence. This analysis begins by describing the reputational problems that are currently thought to beset the industry and the underlying fears about its status and worth that these difficulties disclose. We then examine how security players seek to legitimate the industry using various narratives of professionalization. Four such narratives are identified - regulation, education, association and borrowing - each of which seeks to justify private security and enhance the industry's social worth. What is striking about these legitimation claims is that they tend not to justify the selling of security in market terms. In conclusion we ask why this is the case and argue that market justifications are 'closed-off' by a moral ambivalence that attaches to an industry trading in products which cannot guarantee to deliver the condition that its consumers crave.  相似文献

The literature suggests that corporate diversification destroys firm value. This value destruction is usually considered to be a consequence of managers' pursuing diversification strategies to benefit themselves rather than to increase firm value. This paper provides evidence that casts doubt on this agency theory‐based explanation for corporate diversification. Evidence based on insider trading suggests that managers themselves consider their diversification strategies to be value‐increasing. Specifically, it is documented that corporate insiders (directors) purchase more of their firms' shares in the open market when corporate diversification is high. Moreover, insiders purchase more when the level of diversification discount is high, suggesting that they disagree with outside investors' undervaluation due to diversification. It is also found that the market reaction to insiders' purchases is positively related to corporate diversification. This result suggests that outsiders consider the amount of favourable information contained in insiders' purchases to increase with the extent of corporate diversification.  相似文献

Asking sensitive questions, without risking a terminated interview or response bias, is a major problem in deriving accurate social indicators based on public opinion surveys. This problem has become particularly acute as the topics that interest researchers have become more personal in nature. Mail and telephone surveys, and methods such as the randomized response technique, have all been used to try and overcome this problem, with varying degrees of success. In this paper, we describe an alternative approach using a sealed booklet. We report results from a question-format experiment that asked respondents the same sensitive questions in a sealed booklet, completed in the presence of the interviewer, and in a standard face-to-face interview. The survey used for the experiment was a personal interview survey of drug use based on a national population sample. The sealed booklet format was found to produce more accurate estimates of drug use compared to direct questions. In addition to assuring the respondent greater anonymity, the sealed booklet permits a wide range of questions to be asked and does not limit the analyses that can be conducted on the data.  相似文献

It is widely recognized that population projections are increasingly used in formulating policy in many public and private sectors. However, little information exists on the nature of the projections or their users. This paper reports the results of a survey conducted to rectify this situation. The results confirm that the applications of projections are very broad and that the prime area of increase has been in small-area projections. At this level many users make their own projections rather than use official projections and the paper reviews the methodology used to make these projections. A number of suggestions are made for improving communication between national and subnational producers and local users. We would like to thank the Australian Population Association, and in particular the Secretary, Dianne Rudd, for providing us with address labels of members of the Association. We would also like to thank the Australian Bureau of Statistics, in particular Shail Jain, for advice on the development of the questionnaire. The comments of the two anonymous referees were very helpful. Finally we wish to thank our respondents for their co-operation, and especially those who wrote to encourage us in this work.  相似文献

Often in demography, individuals may change state over time for a variety of reasons. Competing-risks hazards models have been developed to model such situations. This paper describes the extension of the discrete-time competing-risks hazards model to a multilevel framework that allows for data at different levels of aggregation. The model is illustrated with data from the 1988 Chinese National Survey of Fertility and Contraceptive Prevalence, which collected complete contraceptive histories. Women may stop using a method of contraception for a number of reasons; this paper describes how one can control for correlations between the outcomes of repeated spells of contraceptive use.  相似文献

Creative industries are firms which are characterized largely by the labour inputs of creative individuals, and surrounded by a degree of rhetoric as to their significance, but are a comparatively under‐researched sector. In this study we developed a research framework which integrated entrepreneurial cognition, entrepreneurial orientation and firm capabilities and explored the relationships between these variables, market conditions and the performance of small creative industry enterprises. The data suggest that high growth small firms are characterized by well‐developed internal capabilities allied to an entrepreneurial orientation and that the combination of the various sub‐attributes associated with each of these appear to be especially salient under conditions of intense competition. The policies, managerial and educational implications of the findings are discussed.  相似文献

This paper reports an evaluation of a rural activity project for people with learning difficulties. The project is situated in (but not a regular part of) an agriculture college. Both statutory and voluntary interests are represented in the management of the scheme, which is funded by the All Wales Strategy for the Mentally Handicapped through the local authority. Despite the widespread presence of ideas about normalization and carer participation, key stakeholders in the project appeared to draw on various aspects of three different models in describing, assessing and participating in the work of the scheme: a training for work model, a personal and social growth model, and an education for life model. We explore the question of whether such contrasting views can be tolerated in a single project, and their implications for policy and practice decisions. Each model has its distinctive consequences for project aims, selection, programme planning, staffing requirements, future development objectives and desirable project outcomes. The debate has implications for the way in which policies of normalization are operationalized in and beyond the field of learning difficulties.  相似文献
