Through examining the case of people with epilepsy (which, as we demonstrate, has an ambiguous status in relation to both popular and academic conceptions of disability) we explore the fluid, negotiable and contingent nature of identity and, in particular, the identification as ‘disabled’. Disability, we argue, cannot be reduced to either biology or social oppression, or even primarily to biological or social factors: it is the outcome of a complex interaction between a multiplicity of factors – biological, environmental, social, psychological, cultural and political – which will interact and be experienced differently by different people, at different times and in different situations. Rather than conceiving of disability in ‘all or nothing’ terms and of differing explanations as competing and mutually exclusive, it would be more productive to see them as partial and potentially complementary contributions to the better understanding of a complex and multifarious reality.  相似文献

In the current study, tacts with positive qualifying autoclitics for reading were reinforced in order to determine if this procedure would increase the time spent reading by participants. Participants included 5 children, between 9–10 years old. Participants were individually exposed to 4 free operant sessions during which they were instructed to independently choose play activities. During pre- and post-treatment conditions, no consequences were provided for choosing reading. In addition, 4 treatment sessions were conducted on days separate from the free operant session days, during which the experimenter praised each positive reading-related statement emitted by the participant. Following treatment sessions, 4 out of 5 participants increased the time allocated to reading, suggesting that reading could be increased when praise is delivered contingent upon positive reading-related verbalizations.  相似文献

In this paper we pose the question: Does the prevention of brain ageing constitute anti-ageing medicine? We answer the question by looking at recent changes in the knowledge and organisational structure of dementia research, practice and policy and investigating the boundary relations between this disease-specific field and anti-ageing medicine. Drawing on a qualitative study of the ways in which different clinical and scientific constituencies work to define, organise and negotiate the boundaries between normal and abnormal cognitive aging, we suggest that the field of dementia research, practice and policy has experienced internal diversification forming a ‘new space of representation'. We show how this space is structured by two axes: one that relates to how AD is conceptualised and another that concerns the modes of intervention or actions that will prevent the condition in individuals or populations. We argue that while these changes have blurred the epistemic boundaries between dementia and other fields of research, there are still strong institutional, economic and political factors that glue the field together.  相似文献

The inability, or unwillingness, of 20th‐century sociologists to move beyond the agenda bequeathed by Marx, Weber, and Durkheim is remarkable in view not only of the now outdated presuppositions shared by all three but of the increasing likelihood that the more important influence on the human behavioural sciences in the 21st century will turn out to be Darwin's. Not only has the coming together of evolutionary theory, population genetics, and molecular biology shown that significantly more of human behaviour can be explained by the theory of natural selection than was previously recognized, but non‐reductionist explanations of cultural and social evolution from within a neo‐Darwinian paradigm can be framed in terms no longer vulnerable to the criticisms previously levelled against the application to sociology of Darwin's original insight about ‘descent with modification’.  相似文献

Historically, the coverage bias from excluding the United Statescell-only population from survey samples has been minimal dueto the relatively small size of this group. However, the unrelentinggrowth of this segment has sparked growing concern that telephonesurveys of the general public in the United States will becomeincreasingly subject to coverage bias. While there is evidencethat demographic weighting can be used to eliminate this bias,the availability of the weights lag behind the rapidly changingcell-only population. To explain the extent of the problem,we propose a reliable model to forecast cell-only populationsize and demographics. This model posits that a stable behavioralprocess, the rate of habit retention, can be estimated fromprior wireless lifestyle adoption in the United States and mayalso describe adoption of the cell-only lifestyle. Using measuresof incentive and habituation, we test this assumption by predictingchanges in the cell-only population size and changes in agedemographics. The accuracy of predictions confirms the two adoptionbehaviors are similar. We then develop forecasts of age demographicsthrough 2009, and show how cell-only lifestyle adoption leadsto potential coverage bias that is better addressed throughthis type of modeling rather than weighting from historicaldata.  相似文献

Abstract The effect of personalization on mail survey response rates was examined in nine studies that included 17 comparisons under several research conditions. A study of this variable across multiple experiments in five agricultural experiment stations was undertaken because of conflicting results from previous research and from concern that the effectiveness of personalization might have decreased over time. Results show that, while response to general public surveys appeared to increase modestly across all treatment groups, there was no positive effect for populations in which a group identity (e.g., Dear Oregon Gardner or Dear ATV Owner) is employed to address respondents in cover letters. Personalization appears to remain useful for improving response in surveys of the general public.  相似文献

We argue that regional comparison of East Asian and European ethnic return migration policy offers important new perspectives on nationhood, nondiscrimination norms, and trans‐nationality. We find that despite international nondiscrimination norms, preferential ethnic return policy is common in both regions. These policies at least implicitly define the nation as existing across borders. However, there are significant regional differences. East Asian states use co‐ethnic preferences instrumentally for economic goals and also offer preferential treatment of co‐ethnic foreign investors. European states offer preferences to coethnics to protect these populations or express symbolic ties, sometimes at great expense. Thus, in Europe the state has an obligation to assist coethnics abroad, but in Asia, foreign coethnics assist the state.  相似文献
