In the early 1980s, support for trade unions was a significant component of Oxfam GB's programmes in various parts of the world, most notably Central America and South Africa. In Central America, this was motivated both because organised labour played an important role in popular movements that were pressing for equitable political settlements to the wars ravaging the region, and because unions as such, as well as their members and leaders, were the targets of repression and political violence. This article explores the background to the rise in funding for unions in Honduras, reflects on this experience, and discusses some of the factors that might change a potentially awkward donor‐recipient relationship to one of dialogue and solidarity. 相似文献

We present a study of 102 Sudden Infant Death Syndrome (SIDS) deaths using a retrospective review of medical examiner autopsy reports. The prevalence of sleep related risk factors with regards to sleep surface, sleep position, and co-sleeping were determined in a population of infants less than 1-year-old. Of the 102 SIDS deaths, 67 (65.7%) were not in a crib, 63 (61.8%) were prone, and 48 (47.1%) were co-sleeping. However, 94 (92.2%) of these deaths had at least one risk factor present. Only 8 (7.8%) infants had slept alone, in a crib or bassinet, and on their back or side. Infants less than 4-months-old had a higher rate of co-sleeping (54.7%) than the older infants (25.9%), and a higher frequency of heart malformations at post-mortem examination. The older infants were more likely to exhibit pulmonary and tracheal inflammation, and neuropathology. 相似文献

The purpose of this study was to determine the precision and accuracy of facial soft tissue measurement using personal computer (PC)-based multiplanar reconstructed (MPR) computed tomography (CT) images and to evaluate the effect of the various CT scanning protocols on the facial soft tissue thickness measurement. Thirteen different CT imaging protocols were used to image a cadaver head. MPR reformations and three-dimensional (3D) reconstructions viewed on a laptop PC were used to make measurements at six specific sites on each set of images. These measurements were compared to physical measurements at the same sites. Increasing the slice thickness resulted in decreased image quality. Within the same slice thickness, increasing the pitch ratio in the spiral mode, resulted in decreasing image quality. The image quality of conventional CT scanning was relatively poorer than that of the spiral CT scanning. However, the mean deviation from the physical measurement was within 0.43 mm in every instance. This mean deviation was quite small and clinically acceptable for measuring the soft tissue thickness of the facial area. PC-based MPR CT images of the face using routine scanning CT protocols can be used to accurately measure soft tissue thickness in the facial region. However, for more fine and accurate data collection, scanning protocols with slice thicknesses less than 5mm, and a spiral/helical mode pitch less than 2:1 are recommended. 相似文献

This study examined the link between rejection sensitivity, self-silencing behaviors, and depressive symptomatology among adolescent dating couples. Self-silencing was hypothesized to be the process mediating the association between rejection sensitivity and depressive symptoms. Our sample included 211 couples between 14 and 21 who were dating at least 4 weeks. Results indicated that dating adolescents who were sensitive to rejection reported more depressive symptomatology and higher levels of self-silencing behaviors within their romantic relationship compared to dating adolescents who were not so sensitive to rejection. Self-silencing was identified as a partial mediator of the association between rejection sensitivity and depressive symptomatology among dating adolescents. Clinical implications in light of these findings are discussed.

The interest in results‐based policy formulation requires us to examine the impact of evaluations. This article focuses on the production and use of impact evaluations of UK active labour market programmes. It is intended to be useful for non‐evaluators and for those working in developing and transition countries. The UK provides a case study where there is good evaluation data, available expertise and high‐level political commitment to evaluation. However, obstacles remain in the generation and use of impact data. The article seeks to identify the opportunities and difficulties faced in the UK, and it considers the implications for other countries. It suggests that the measurement of impact concepts will prove difficult in countries that do not have sound administrative data, comprehensive labour market statistics and well‐established macroeconomic and tax‐benefit models. Furthermore, the use of evaluation data may be limited by a range of factors, most crucially those emanating from the legislative and policy‐making environment. The conclusion is that if knowledge‐based policy management is to be improved, changes in evaluation methodology will only be effective if supported by changes in the wider government environment.

Although leadership is typically seen as coming from the leaders of governments and major institutions, a strong case can be made that concerned citizens first articulate important issues and policies that official leaders then pick up and promote. In a market-based society dominated by large corporations, Hirschman's framework of exit, voice, and loyalty can be used to relate consumer and grassroots movements to markets, when participants believe there is no exit and loyalty (or acquiescence) is not an option. While "voice" is usually applied to the individual or consumer level, this article develops the concept of organized voice and illustrates how it has exhibited leadership in the controversial relations between the biotech and pharmaceutical industries and society as a whole. The essay concludes by urging more research on organized voice as a source of leadership and by outlining some important dimensions for researchers to consider. 相似文献

This study seeks to expand on the previously reported validity of the Static-99, RRASOR, MnSOST-R, and SORAG in predicting sexual recidivism utilizing a regional sample of offenders. The predictive validity of each test was determined utilizing subgroups of the sample based on each offender's known offense history. The effectiveness of each instrument varied depending on offender type. The Static-99 and SORAG were both significantly predictive of sexual, violent, and any recidivism for extra-familial child molesters, and all four tests were predictive of violent or any recidivism in this subgroup. For incest offenders, all four tests were at least moderately predictive of sexual recidivism, whereas the Static-99 and the SORAG were highly predictive of violent or any recidivism. None of the four tests established consistent predictive validity across recidivism categories in regard to rapists or hands-off offenders, however, the Static-99 and the SORAG were significant in terms of sexual recidivism. 相似文献
