A new procedure for testing the H 0: μ1 = ··· = μ k against the alternative H u :μ1 ≥ ··· ≥μ r ≤ ··· ≤ μ k with at least one strict inequality, where μ i is the location parameter of the ith two-parameter exponential distribution, i = 1,…, k, is proposed. Exact critical constants are computed using a recursive integration algorithm. Tables containing these critical constants are provided to facilitate the implementation of the proposed test procedure. Simultaneous confidence intervals for certain contrasts of the location parameters are derived by inverting the proposed test statistic. In comparison to existing tests, it is shown, by a simulation study, that the new test statistic is more powerful in detecting U-shaped alternatives when the samples are derived from exponential distributions. As an extension, the use of the critical constants for comparing Pareto distribution parameters is discussed. 相似文献

Breakdown point is one measure of the robustness of an estimate. This paper discusses some unusual properties of the breakdown points of M-estimates of location. 相似文献

Past research on care leavers has, understandably, tended to focus on those who are in their mid‐ to late‐teens or early 20s. This reflects the profound impact of central and local government policy on those young people. It also reflects their prominence in contemporary analyses of most of the indicators of social exclusion among young people in the UK – unemployment, homelessness and lack of educational qualifications among them. However, some issues affecting adults who grew up in care apply across the life course. One such issue is the access that former care adults have to their child care files. Indeed, as we shall see, this issue has particular importance for many older adults (in their 30s and upwards). Policy and practice in this field has changed significantly during the past 20 years and there is a growing awareness of the needs of former care adults in this area. Access to such files can be a significant element in the process of seeking to address identity concerns centring around family and childhood experiences. This paper explores some of these identity concerns and analyses how access to care files both reflects such concerns and attempts to address them. 相似文献

Summary. We present several new measures of gross-output-based total factor productivity (TFP) at the sectoral level for manufacturing industries in the G-7 economies. We calculate measures of both TFP growth and comparative levels. These are obtained by combining conventional Organisation for Economic Co-operation and Development sectoral data on labour and capital inputs with data on intermediate inputs from national input–output tables. Additionally, we derive cyclically corrected measures of TFP growth. Our evidence shows that the considerable gap in TFP between the USA and other G-7 economies is closing but remains significant. 相似文献

The literature on adolescent male prostitution is scant. The few existing papers tend to focus on the status of adolescent runaways coerced into prostitution within large cities. This article describes prostitution in a midsized midwestern city without many of the anticipated preconditions. Such practice may be more common than is normally assumed. 相似文献

This article uses a qualitative approach to elicit the views of 31 professionals who provide services to vulnerable young men. The findings reveal six key themes following focus group interviews: (i) the importance of masculinity in explaining problematic behaviour; (ii) the misuse of alcohol and drugs; (iii) alienation and social isolation; (iv) concerns about suicide and self‐harm; (v) the quality of existing services; and (vi) recommendations for changes to services. Service providers generally acknowledged the social context in explaining these behaviours and argued for enhanced services and a more developed skills base in working with vulnerable young men. 相似文献

Responding to the question implicit in the title of the 1985 National Family Therapy Conference ‘Coming of Age’, the author argues that Australian family therapy still has a number of issues to face before it can be said to be a mature and independent adult. The paper focuses on three issues — ideology in family therapy, theory for practice, and practice itself— and raises questions about the adequacy of Australian family therapy's theoretical maturity, suggesting that there is still too much reliance on the ‘new’ and on the ‘guru’ rather than on a solid building on therapeutic experience. 相似文献
