ABSTRACTThe authors discuss service user involvement as a key approach regarding training of social workers. In many European Union countries this is a stable practice with a lengthy tradition in research and application. However, in Poland it is almost entirely absent and marginalized. This article presents the results of a participatory action research project conducted at the Institute of Sociology of the Jagiellonian University in Krakow, the objective of which was to identify and critically analyze the key substantive and formal aspects of training of social workers with the participation of individuals with experience of mental illness. This research project adopted an open approach to cognizing reality based on qualitative co-participatory methods. In the conclusion, the authors emphasize that the fundamental criterion for the success of this particular form of training is voluntary and differentiated participation of students—both in the role of people sharing their own experience and as learners—as well as shaping a culture of open dialogue, educational alliances of recognition and recovery, the foundation of which is axiological experience. 相似文献

The aim of this article is to explore the new lives of prewar photographs of European Jewry. In particular, I employ the concept of ‘orphan photograph’ which describes any work whose owners, producers, and the subjects featured in them are no longer available. Working from the premise that a photograph is not only a two-dimensional representation but also a three-dimensional object, I show how family images are consumed, distributed, discarded, salvaged and brought back to life. As I argue in this article, with the annihilation of their owners the once-important personal meanings of the pictures become obscured and obliterated. Subsequently, in post-Holocaust culture orphan photographs become invested with collective values. In the process of being recycled, these private family photographs are transformed into public spaces through which new visions of the past are projected and group interests promoted. Drawing on two case studies from Poland, I look at the ways in which these orphaned images are used by writers and NGOs, and examine how the various agents affect the subsequent readings of these artefacts. The article shows that once allowed to ‘speak for themselves’ these images reveal an immense capacity to challenge our pre-set notions of the past and escape the ‘backshadowing’ narrative of the Shoah. 相似文献

Spanish-speaking and culturally sensitive social workers are in high demand throughout the country to work with Latino clients. Latinos currently represent about 11% of active social workers, limiting the capacity of social work to effectively address the needs of the Latino population. Despite this shortage, little attention has been paid to the recruitment and retention of Latinos in social work. This article presents a case study that examines a BSW program accredited by the Council on Social Work Education, at a bilingual, private college where 90% of students self-identify as Latinos. It details how the BSW program builds on the students’ community cultural wealth to ensure continued recruitment and retention of Latino students. Implications for social work education are discussed. 相似文献

In this paper, we show that proportions of observations that fall into a random region determined by a given Borel set and a central order statistic converge almost surely, provided that the corresponding population quantile is unique. We also describe three types of possible asymptotic behaviour of these proportions in the case of non-unique population quantile. As an application of our findings we establish limiting properties of numbers of ties with a central order statistics in a discrete sample. Our results are derived not only for independent and identically distributed observations but more generally for strictly stationary and ergodic sequences of random variables. 相似文献

In the article, properties of the Bennett test and Miller test are analyzed. Assuming that the sample size is the same for each sample and considering the null hypothesis that the coefficients of variation for k populations are equal against the hypothesis that k ? 1 coefficients of variation are the same but differ from the coefficient of variation for the kth population, the empirical significance level and the power of the test are studied. Moreover, the dependence of the test statistic and the power of the test on the ratio of coefficients of variation are considered. The analyses are performed on simulated data. 相似文献

In this paper, we assume that the duration of a process has two different intrinsic components or phases which are independent. The first is the time it takes for a trade to be initiated in the market (for example, the time during which agents obtain knowledge about the market in which they are operating and accumulate information, which is coherent with Brownian motion) and the second is the subsequent time required for the trade to develop into a complete duration. Of course, if the first time is zero then the trade is initiated immediately and no initial knowledge is required. If we assume a specific compound Bernoulli distribution for the first time and an inverse Gaussian distribution for the second, the resulting convolution model has a mixture of an inverse Gaussian distribution with its reciprocal, which allows us to specify and test the unobserved heterogeneity in the autoregressive conditional duration (ACD) model.
Our proposals make it possible not only to capture various density shapes of the durations but also easily to accommodate the behaviour of the tail of the distribution and the non monotonic hazard function. The proposed model is easy to fit and characterizes the behaviour of the conditional durations reasonably well in terms of statistical criteria based on point and density forecasts. 相似文献
