Recent events have focused attention on the perceived widening of the economic divide between urban and rural areas, and on the continued rise of national income inequality. We demonstrate that, in fact, the average income gap between urban (metropolitan) and rural (nonmetropolitan) households has not risen over the past 40 years, and makes virtually no contribution to national income inequality. Rising national inequality is driven by rising inequality within both urban and rural America, not by an urban/rural divergence. As is well known, the growing dispersion of household money income is partly driven by rising wage inequality, particularly in urban areas. Less well recognized is the role played by other income sources. We show that a decline in the progressivity of the distribution of social security payments and cash transfers, and an increase in the regressivity of the distribution of retirement incomes, have jointly made a comparably large contribution to rising income inequality. At the same time, the share of income from self-employment has declined, particularly in rural America, and because self-employment income is very unequally distributed, its diminution has retarded the growth of rural inequality. In 2014–15, however, rural inequality increased, cutting the urban/rural inequality gap in half. 相似文献

The proportion of young people taken into the care of the state has increased recently and there is evidence that this social group suffer negative long‐term outcomes that might be conceptualised by the emergent criminological category of ‘social harm’. Debates in social work around an ethics of care and justice offer different ways of thinking about responding to social harm. This paper reports findings from an innovative arts‐based intervention with Looked After Children and young people and concludes that holding these competing value sets in creative tension is central to the success of the programme in helping young people to cope with and contest social harm. 相似文献

Continuous improvement (CI) has played a key role in Japan's quality management. U.S. companies have begun to adopt CI in recent years. This paper studies the implementation of CI in seven U.S. manufacturing companies. We view values as the core concept of culture that impacts CI effectiveness. Using both qualitative and quantitative data with a sample of seven companies, we observe empirically a relationship between process-oriented values and CI effectiveness. We also find that communications involving workers is strongly associated with CI effectiveness. Finally, we find an association between process orientation and communication frequency, and argue that communications act as an intervening variable between process orientation and effectiveness. 相似文献

The existing literature on the determinants of income redistribution has identified a ‘paradox’. Namely, that countries with a high degree of market income inequality redistribute little, which is in disagreement with the median voter theorem. In a first step, this paper outlines several mechanisms that explain why government corruption might be partially responsible for this ‘paradox’. In a second step, different corruption perception indices and an instrumental variable approach are used to provide empirical evidence that indicates a significant negative impact of corruption on redistribution levels for a sample of 148 developing and developed countries. This finding suggests that, next to political and need factors, government corruption explains to some extent the ‘paradox of redistribution’. This is especially true for many developing countries, given that they typically have relatively high degrees of corruption and low levels of redistribution. 相似文献

Specific efforts by hospital accreditation organizations encourage renovation of nursing stations, so nurses can better see, attend, and care for their patients. The purpose of this study was to examine the effect of nursing station design on the therapeutic milieu in an adult acute care psychiatric unit. A repeated cross-sectional, pretest-posttest design was used. Data were collected from a convenience sample of 81 patients and 25 nursing staff members who completed the Ward Atmosphere Scale. Pretest data were collected when the unit had an enclosed nursing station, and posttest data were collected after renovations to the unit created an open nursing station. No statistically significant differences were found in patient or staff perceptions of the therapeutic milieu. No increase in aggression toward staff was found, given patients' ease of access to the nursing station. More research is needed about the impact of unit design in acute care psychiatric settings. 相似文献

Although some attempts are being made to increase children's participation in Norwegian child protection cases, much needs to be done in order to comply with the participation principle in the United Nations Convention on the Rights of the Child. This paper reports on a study of factors that are likely to predict if social workers will attempt to give children an effective voice in decision making processes. 53 child protection case managers and 33 social work students participated in a questionnaire survey in which they were asked to agree or disagree with 20 statements about child participation. Statistical factor analysis was used in order to identify underlying factors in the dataset. The results suggest three main reasons for children not being allowed to participate: communication difficulties (communication factor); because child participation was not deemed necessary (participation advocacy factor); or that participation was considered inappropriate because it might be harmful (protectionism factor). This research suggests that, if we are to improve participation within the child protection system, formal regulations and guidelines need to be accompanied by a greater attention to development of social work skills in working with children through participatory processes.

The fifth revision of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) is scheduled for publication in 2013. It will include several changes to the diagnosis of pathological gambling: the name of the disorder will be altered, the threshold for diagnosis will decrease, and one criterion will be removed. This paper reviews the rationale for these changes and addresses how they may impact diagnosis and treatment of the disorder, as well as potential for future research in the field. 相似文献

Experiential learning is a vital aspect of social work education, particularly for teaching community practice. The literature, however, provides few examples of technology-based experiential assignments that educators can implement in their classrooms. This exploratory study examined an innovative student-generated video assignment developed for a social work community practice course. Thirty-seven former students spanning three distinct semesters completed an online survey of closed- and open-ended questions. Findings indicate the video assignment enhanced understanding of community practice and provided a unique diffusion factor. Participants appreciated how the video assignment differed from traditional assignments by offering opportunity for praxis, creativity, and acquisition of technological skills. Educators should note the challenges of student-generated videos to maximize their educational benefit and sustain student receptivity to such assignments. Teaching video-making skills has implications for post-graduation employment in the human service sector. 相似文献
