Social work as art revisited   总被引:1,自引:1,他引:0  
In this article we revisit 'social work as art', noting that it is just over 20 years since England's book on the subject provided a direction for the profession's early defence against empiricism. Those who picked up the ball handed to them by England tended to focus discussions of social work's 'art' on its soft side, embedding it in notions of 'creativity', 'meaning', 'self-expression', 'intuition' and 'quality', all of which were said to characterise the 'aesthetic dimensions' of social work practice as a counterpoint to the rising tide of hard empiricism, proceduralism and managerialism. Within these 'aesthetic dimensions', proponents of social work as art sought to resolve tensions through advocating a value-based 'artistic' approach to care. Against this we argue that art is struggle and resolution, soft and hard, joy and grief. Further, we posit that social work's art lies not in the social worker as artist but rather in social work as the 'work' of art, which is implicitly a 'non-productivist' endeavour. In a fundamental sense we argue that it is the art of social work and not the social worker that assembles what is practice, that provides bounds and lets everything stand in relation to everything else. This enables us to construct a speculative 'radical agonistics' for social work that draws attention to the relation between art, truth and event. In so doing, we substitute a subjectivist reading of social work as art with an ontological analysis drawing on Heidegger's phenomenology, supplemented by the work of Alain Badiou, to cast social work as art first, as artistic attunement, and second, as an art in the service of a politics of liberation.  相似文献

The article offers insights on the peer-review process as it relates to scientific and technical reports used to inform regulatory decisions. Used effectively, peer review is a powerful tool for advising organizational leaders whether the scientific foundations of their decisions can be expected to withstand scrutiny as rule-making products move through interagency reviews, public comment and stakeholder processes, congressional oversight, and judicial review. The emphasis is "heads up" rather than "how to." That is, without delving into myriad technical and administrative details, the discussion highlights nine fundamental "leadership responsibilities" that determine the nature and course of peer review.  相似文献

More than 30 years have passed since palliative care was introduced in the United States, and what began as a small rebellion has evolved into a fairly large health care industry. Although the palliative care movement has considerably improved the care given to those at the end of life, many challenges remain for palliative care providers in the United States. This article discusses the history of hospice and palliative care in the United States, the Medicare Hospice Benefit, the growth of hospice and palliative care, and challenges such as the need for regulatory change, workforce issues, improving access to care, and improving the quality of palliative care.  相似文献

A common approach to analysing clinical trials with multiple outcomes is to control the probability for the trial as a whole of making at least one incorrect positive finding under any configuration of true and false null hypotheses. Popular approaches are to use Bonferroni corrections or structured approaches such as, for example, closed-test procedures. As is well known, such strategies, which control the family-wise error rate, typically reduce the type I error for some or all the tests of the various null hypotheses to below the nominal level. In consequence, there is generally a loss of power for individual tests. What is less well appreciated, perhaps, is that depending on approach and circumstances, the test-wise loss of power does not necessarily lead to a family wise loss of power. In fact, it may be possible to increase the overall power of a trial by carrying out tests on multiple outcomes without increasing the probability of making at least one type I error when all null hypotheses are true. We examine two types of problems to illustrate this. Unstructured testing problems arise typically (but not exclusively) when many outcomes are being measured. We consider the case of more than two hypotheses when a Bonferroni approach is being applied while for illustration we assume compound symmetry to hold for the correlation of all variables. Using the device of a latent variable it is easy to show that power is not reduced as the number of variables tested increases, provided that the common correlation coefficient is not too high (say less than 0.75). Afterwards, we will consider structured testing problems. Here, multiplicity problems arising from the comparison of more than two treatments, as opposed to more than one measurement, are typical. We conduct a numerical study and conclude again that power is not reduced as the number of tested variables increases.  相似文献

We generate models predicting wives' and husbands' feelings of overall balance across roles. Drawing on fine‐grained data about marital lifestyles and time use, we find few predictors that are the same for both partners. Both report greater role balance when their level of parental attachment to children is higher and when their marital satisfaction is greater, but gendered time use gives rise to important differences. Wives report greater balance when they have more paid work hours but have fewer of these hours on weekends. Wives' balance is also greater when they feel less financial strain, have less leisure time alone with their children, more couple leisure alone with their husbands, and more social network involvement. Husbands' contribute to wives' balance when they report more relationship maintenance in the marriage and more leisure with their children at those times when wives are not present. Husbands' own role balance increases as their income rises, but it decreases as their work hours rise. Husbands' balance also rises with more nuclear family leisure, and it lessens as their leisure alone increases. Our discussion highlights the ways that gendered marital roles lead to these different correlates of balance.  相似文献

Effects of residential density on sonoran desert nocturnal rodents   总被引:3,自引:3,他引:0  
We compared nocturnal rodent distributions among residential developments and in adjacent undeveloped native habitat remnants in Tucson, Arizona during October 1994. We trapped rodents in 2 low density (0.5 houses/ha) developments, 2 medium density (7.5 houses/ha) developments, and in 4 adjacent blocks of undeveloped native habitat using trap lines of 50 snap traps spaced at 2 traps every 10 meters. We compared species abundance, species richness, and total abundance among the 4 site types in a contingency table using a 2-tailed Fisher's exact test, and used post-hoc tests where the null hypothesis of no difference among sites was rejected. We encountered 144 individuals representing 5 species of nocturnal rodents in 1200 trap nights. Of 4 native rodent species, none were captured in medium housing density sites. House mice (Mus musculus) were captured only in medium housing density sites. Total rodent abundance was lower in both the medium density residential and the adjacent undeveloped sites than in either low density or adjacent undeveloped sites. Low density housing must be included in the developing matrix if the full complement of native nocturnal rodents is to be retained in Tucson.  相似文献

We show that, in the context of double-bootstrap confidence intervals, linear interpolation at the second level of the double bootstrap can reduce the simulation error component of coverage error by an order of magnitude. Intervals that are indistinguishable in terms of coverage error with theoretical, infinite simulation, double-bootstrap confidence intervals may be obtained at substantially less computational expense than by using the standard Monte Carlo approximation method. The intervals retain the simplicity of uniform bootstrap sampling and require no special analysis or computational techniques. Interpolation at the first level of the double bootstrap is shown to have a relatively minor effect on the simulation error.  相似文献

This paper considers the estimation of Cobb-Douglas production functions using panel data covering a large sample of companies observed for a small number of time periods. GMM estimatorshave been found to produce large finite-sample biases when using the standard first-differenced estimator. These biases can be dramatically reduced by exploiting reasonable stationarity restrictions on the initial conditions process. Using data for a panel of R&Dperforming US manufacturing companies we find that the additional instruments used in our extended GMM estimator yield much more reasonable parameter estimates.  相似文献

In the Brazilian Amazon during the 1980s,urban population growth outstripped rural growth, andby 1991, most of the region's population resided inurban areas. Much of this urban growth involvedestablishment of unplanned housing with inadequateinfrastructure, which resulted in rising pollution. This paper compares indicators of environmentalquality in urban populations of the Amazon in 1980 and1991, and among different kinds of urban populationsin 1991. The results show that environmental qualityin the region deteriorated during the 1980s as theproduction of and exposure to environmental hazardsrose while resources to ward off hazards eroded. Thefindings also show that environmental quality wasparticularly poor in more rapidly growing urbancenters. The urban Amazon may not afford an adequatestandard of living and this may generate out-migrationfrom the region.  相似文献
