Even though disabled children are targets of various forms of abuse, such issues remain mostly undocumented open secrets in many countries including Ghana. The article is based on a qualitative data provided by three key informants. Six stories emerged from the data and are discussed in terms of four main forms of abuse. Labelling theories are employed to strengthen the discussions. The article is aimed at increasing awareness on the various forms of abuse experienced by disabled children in Ghana. The study is also meant to capture the attentions of stakeholders that have the responsibility to end abusive practices against disabled children in Ghana. 相似文献

Political-economic classics of different schools agreed that capitalism inherently and inevitably leads to a decline of market principles. We analyze indicators of liberalization policies for 21 OECD-countries in five economic and social policy fields and demonstrate that western industrialized countries are subject of a convergent trend towards market-creating policies??in stark contrast to the theoretical expectations of several political economy authors. At the latest during the first half of the eighties, the western democracies entered a new phase of economic liberalization, which continues up to the present. A methodological implication of our findings suggests that the methods of causal analysis of convergent liberalization policies may not be the same as those who have been applied for the analysis of development and consolidation of the varieties of capitalism in the postwar era. 相似文献

This study examines new immigrants from the former USSR, their attitudes, expectations and the awareness of change in themselves and in their fellow immigrants. Participants demonstrated attitudes toward the new society which differed dramatically depending on the sphere of life being examined: cultural, institutional, or quotidian. Participants displayed a tendency toward integration in the institutional and quotidian spheres, but not in the cultural. An attitude toward integration did not automatically lead to an awareness of change in the new immigrants themselves. Participants consistently reported higher degrees of change in fellow immigrants in comparison to themselves. The issue of preservation of self‐identity through socio‐cultural conservation is discussed, as well as the relevance of these findings for Vygotsky's cultural‐historical theory and Feuerstein's theory of mediated learning. 相似文献

In many statistical problems, maximum likelihood estimation by an EM or MM algorithm suffers from excruciatingly slow convergence.
This tendency limits the application of these algorithms to modern high-dimensional problems in data mining, genomics, and
imaging. Unfortunately, most existing acceleration techniques are ill-suited to complicated models involving large numbers
of parameters. The squared iterative methods (SQUAREM) recently proposed by Varadhan and Roland constitute one notable exception.
This paper presents a new quasi-Newton acceleration scheme that requires only modest increments in computation per iteration
and overall storage and rivals or surpasses the performance of SQUAREM on several representative test problems. 相似文献

Recently, there have been advances in the development of multidimensional poverty measures. Work is needed however on how to implement such measures. This paper deals with the process of selecting dimensions and setting weights in multidimensional poverty measurement using qualitative and quantitative methods in a participatory framework. We estimate the multidimensional poverty measures developed by Alkire and Foster for a particular group: persons with psychiatric diagnoses in the United States. To select relevant dimensions and their relative ordering, two discussion groups are convened: one consisting of persons with lived-experience expertise and the other consisting of people with mental health service provision or research expertise. Several methods are used to convert dimension rankings into weights. The selection and ordering of dimensions differed between the two discussion groups, as did the resulting poverty measures. For instance, the poverty headcount using the dimensions and weights of the ‘lived experience’ group ranged from 20.61 to 26.96% as compared to a range of 18.62–33.19% using those of the ‘provider/researcher’ group. One of the main results of this study is that the Alkire Foster method is sensitive to the selection of dimensions and the methods used to derive rankings and weights. It points toward the limitation of relying exclusively on small scale qualitative methods for the selection and ranking of dimensions. In addition, the participatory framework used in this study was found to be essential in interpreting results, in particular with respect to the limitations of the data set in measuring relevant dimensions. 相似文献

The presence of shared implicit theories of performance is used in explaining the failure of behavioral anchors to improve performance ratings. It is proposed that efforts to improve rating accuracy also will be hampered by a preoccupation with observation. Instead, attention needs to be focused on the inferential accuracy of the rater and the cognitive processes and implicit theories upon which raters rely. 相似文献

Within a growing Knowledge-Management context, it would appear that Management Research calls for researchers to explicitly understand their own values, have increasing capacity for reflexivity and anticipate various ethical dilemmas that emerge from the research endeavour. This paper provides an overview of the philosophy of ethics and focuses on a researcher's ethical reasoning. It provides a framework for understanding causes of ethical dilemmas in the context of management research and provides strategies for a way forward through such dilemmas. The paper, finally, outlines exercises pertinent to research ethics and ‘hands on’ research praxis. 相似文献
