Correspondence to John Harris, School of Health and Social Studies, University of Warwick, Coventry CV4 7AL, UK. E-mail: j.harris{at}warwick.ac.uk Summary The notion that social work is an international profession,operating with generally similar goals, methodologies, and commonvalues is considered critically. Examining the political andsocial contexts of three countries with liberal democratic governments—Australia,Britain and the United States—the role of social workwithin the welfare processes of each country is compared. Whilesocial work as an identifiable professional activity sharessome features, it is argued that the idea of its having a coreessence needs to be tempered with a realistic assessment ofthe importance of contextually created difference. Recent andrapid developments in the institutional context, such as thoseexperienced in these three countries, further underscore thelimited utility of the notion of a common professional project.  相似文献

A survey of all social services departments in England was undertakenin order to identify and investigate current work concerningthe participation of disabled children within decision makingregarding their own care and in service development. Developinga culture of, and good practice in, children’s participationis integral to government policy. Results demonstrate that disabledchildren are being involved in a range of decision-making areas;however, participation is not yet embedded or sustained acrossall social services departments, and the involvement of disabledchildren at a higher strategic level is still rare. The participationof disabled children needs further development including moreevidence on which factors can support and promote disabled children’seffective participation.  相似文献

The growing relative number, the improved economic well-being, and the migration of elderly retirees is not only reshaping the social and economic structure of many areas, it is also modifying both long-term and short-run patterns of economic growth. Transfer payments and property incomes, two of the most important source of elderly income, have been among the leading sources of national income growth over the past several decades. Unlike most labor-related industry sources of earnings, the level of transfer payments and property incomes received by the residents of the region is not directly dependent upon local economic activity. Consequently, as transfer payments and property incomes of elderly retirees become increasingly important sources of income and purchasing power within a region, they also can alter regional short-run cyclical patterns of income growth. This article examines the pattern of growth of transfer payments and property incomes in the context of national economic cycles, and explores the implication of those findings on metropolitan and nonmetropolitan Nevada economies.  相似文献

This article describes an application of a method for assessing risks associated with the introduction of an organism into a new environment. The test organism was a binucleate Rhizoctonia fungal isolate that has potential for commercial development as a biological control agent for damping-off diseases in bedding plants. A test sample of host plant species was selected using the centrifugal phylogenetic host range principles, but with an emphasis on economic species. The effect of the fungus on the plant was measured for each species and expressed on a logarithmic scale. The effects on weights of shoots and roots per container were not normally distributed, nor were the effects on the number of plants standing (those which survived). Statements about the effect on the number standing and the shoot weight per container involved using the observed (empirical) distribution. This is illustrated with an example. Problems were encountered in defining the population of species at risk, and in deciding how this population should be formally sampled. The limitations of the method are discussed.  相似文献

In this paper we analyse the provision of housing for disabled people in both its historical and ideological contexts. While the recent extension of part M of the Building Regulations to dwellings by the government represents a significant advance towards the inclusion of disabled people, we argue that the shift in funding of public housing from a 'bricks and mortar' subsidy to Housing Benefit potentially creates greater dependency. This amounts to a policy contradiction in which the government is punishing disabled people for being dependent whilst simultaneously being the cause of their dependency. If this issue is not addressed disabled people will continue to remain excluded, albeit within accessible dwellings.  相似文献

One essential requirement for the development and vitality of a discipline is a network of channels for knowledge dissemination. These channels, such as scholarly journals, furnish not only a means for knowledge sharing, but also for knowledge generation by the discipline's community of researchers. In the field of operations management (OM), there have been several studies that have sought to rank journals relevant to OM research, using opinion surveys, citation analyses, and author affiliations. However, each of these methods has some limitations. This paper adopts a new approach for discerning journal publication patterns in the OM field. It is based on an examination of the actual publishing behaviors of all full-time, tenured OM researchers at a sizable set of leading research universities in the US. This behavior-based methodology provides three metrics that individually, and in tandem, give a basis for rating publication outlets for OM research in terms of their relative importance. The ratings can be used by scholars and administrators to assist in monitoring, disseminating, and evaluating OM research outlets.  相似文献

This article investigates the discourse individuals use when talking about desisting from criminal offending. I analyze the links between offenders’ accounts of past negative behavior, their construction of their possible “clean” future selves, and the social and structural conditions in which they were raised and continue to be embedded. Applying Scott and Lyman's (1968) framework on accounts and Markus and Nurius's (1986) framework of possible selves to interview data with twenty‐eight criminal offenders, I illustrate how excuses for past behavior provide a way for people to distance themselves from their past selves in attempts to preserve or re‐create a possible self that is still worthy to be redeemed in the future. This discourse becomes one mechanism that motivates individuals to change their lives—but it can be short‐lived. The analysis highlights how limited structural opportunities influence individuals’ lifestyles and behaviors, how individuals approach the desistance process even in the face of structural deprivation, and how they attempt to sustain this desistance process.  相似文献

The investigation of multi-parameter likelihood functions is simplified if the log likelihood is quadratic near the maximum, as then normal approximations to the likelihood can be accurately used to obtain quantities such as likelihood regions. This paper proposes that data-based transformations of the parameters can be employed to make the log likelihood more quadratic, and illustrates the method with one of the simplest bivariate likelihoods, the normal two-parameter likelihood.  相似文献

This paper is concerned with an exploration of the role of the long range planner, whether in the private or public sector of the economy, and the impact made upon the processes of his work by government's increasing propensity to manipulate the economy. The authors' researches over the last 2 years into the comparative nature of planning processes in the U.K. economy have made it abundantly clear to them that planners are increasingly concerned at the dangerous potential of such impact upon their forecasting procedures. The emphasis here will rest upon the planner in private enterprises, although the authors' work in both local government and the nationalized enterprises suggest that the problem is of equal importance in these sectors.The authors consider first the past nature of the search processes in long range planning and the context of such attempts to narrow down the range of variables that form the enterprise's perception of its future. Secondly, they examine the emerging discontinuity and the changing role of government, with particular reference to indicative planning concepts. Then they introduce some of the findings of a recent survey of attitudes towards long range planning in the construction industry of the U.K., a sector vitally influenced by turbulence in the economy and with particular interest in government's ideas of macro-planning. Finally Edwards and Harris examine the implications to government and to planners of their findings.  相似文献

The estimation of micro-organism concentrations from dilution plate data is discussed for situations where expected counts are not proportional to the amount of sample per plate. Aspects of design and analysis are investigated in relation to an alternative non-linear model in which the concentration is given by the slope at the origin. This exponential model generally provides a good fit to available experimental data. Simulations show that estimators based on the model perform well when the response is non-linear and remain reasonably efficient when the response is linear.  相似文献
