This article offers two case studies of community development work undertaken in Greater Manchester, United Kingdom, focusing on a Somali Women's Health Day and the work of a community arts project with Asian women, Black Issues in Community Arts/Karishma. The analysis of the operation of racialised borders and the role of women's work in mediating these definitions of community is taken as a critical aspect of community development. Theoretical development of ideas about community development across division and difference draws on recent feminist theory on themes of hybridity and community. In both the accounts of practice and the theoretical debates, translation is the central practice analysed. Este artículo ofrece estudios de dos trabajos de desarrollo comunitario que tuvieron lugar en Greater Manchester en el Reino Unido. Se centra en un Día de la Salud de Mujeres Somalias y en un proyecto artístico entre mujeres provenientes del subcontinente de India llamado ‘Temas de Raza Negra en Artes Comunitarias/Karishma’. Se considera que el análisis de la operación de fronteras racistas y del rol de las mujeres en mediar estas delimitaciones es un aspecto crítico de desarrollo comunitario. Se recurre a la teoría reciente femenista sobre temas de hibrididad y comunidad para el desarrollo teórico de ideas acerca del desarrollo comunitario a través de división y diferencia.  相似文献

Open Day, in the form of two half day single session family clinics, has operated weekly in the ACT Child and Adolescent Mental Health Service since April 1993 and over a thousand families have been seen. Clinicians are often resistant to the concept of single sessions and frequently overestimate the amount of assistance that clients feel they require. However in an era of sharply increasing demand for services, selective use of single family sessions for milder problems, screened by a telephone intake process, has value to both families and workers. Telephone follow-ups of 100 families in 1994 and 70 families in 1996 found that single session family interviews were well accepted by the large majority of families seen. Clinicians see the program as reducing pressure from clients for early attention, enhancing client motivation when seen at crisis times, providing readily available consultation support from peers, increasing learning opportunities and building inter-disciplinary team work.  相似文献

In this paper, we describe an analysis for data collected on a three-dimensional spatial lattice with treatments applied at the horizontal lattice points. Spatial correlation is accounted for using a conditional autoregressive model. Observations are defined as neighbours only if they are at the same depth. This allows the corresponding variance components to vary by depth. We use the Markov chain Monte Carlo method with block updating, together with Krylov subspace methods, for efficient estimation of the model. The method is applicable to both regular and irregular horizontal lattices and hence to data collected at any set of horizontal sites for a set of depths or heights, for example, water column or soil profile data. The model for the three-dimensional data is applied to agricultural trial data for five separate days taken roughly six months apart in order to determine possible relationships over time. The purpose of the trial is to determine a form of cropping that leads to less moist soils in the root zone and beyond. We estimate moisture for each date, depth and treatment accounting for spatial correlation and determine relationships of these and other parameters over time.  相似文献

Real option investments benefit from the flexibility associated with the possibility of abandonment should investment returns prove insufficient. But a firm also benefits from making commitments that engender reciprocal commitments on the part of employees and partner firms, and that allow the firm to address markets that exhibit increasing returns with the speed and scale required for success. I investigate the conditions under which large firms commit to investments in small firm equity alliances and acquisitions, and find that large firms commit to relationships that they initiate and that are subject to a high degree of rivalry. Uncertainty was not a significant predictor of the choice to commit. My findings point to the discretionary nature of the choice to commit and to firms' willingness to commit to investment decisions, despite high uncertainty, during periods of strong growth.  相似文献

This research is intended to ascertain factors related to intrusion of home-based work into the life of the family, and identify the relative impact of characteristics of the home-based worker, his or her family, and the business on intrusions. Logistic regression was used to examine three types of intrusions. Seeing clients at home more than once a week is almost exclusively a function of the characteristics of the work; receiving telephone calls daily and frequently sharing space are functions of the characteristics of the work and of the worker. Understanding the nature of intrusions can help advise families contemplating home-based work and help home-working families find a balance between family demands and work.  相似文献

Receiver operating characteristic (ROC) curves play a central role in the evaluation of biomarkers and tests for disease diagnosis. Predictors for event time outcomes can also be evaluated with ROC curves, but the time lag between marker measurement and event time must be acknowledged. We discuss different definitions of time-dependent ROC curves in the context of real applications. Several approaches have been proposed for estimation. We contrast retrospective versus prospective methods in regards to assumptions and flexibility, including their capacities to incorporate censored data, competing risks and different sampling schemes. Applications to two datasets are presented.  相似文献
