Bayesian analysis of mark‐recapture data with travel time‐dependent survival probabilities

The authors extend the classical Cormack‐Jolly‐Seber mark‐recapture model to account for both temporal and spatial movement through a series of markers (e.g., dams). Survival rates are modeled as a function of (possibly) unobserved travel times. Because of the complex nature of the likelihood, they use a Bayesian approach based on the complete data likelihood, and integrate the posterior through Markov chain Monte Carlo methods. They test the model through simulations and apply it also to actual salmon data arising from the Columbia river system. The methodology was developed for use by the Pacific Ocean Shelf Tracking (POST) project.     

Withdrawn,strong, kind,but de-gendered: non-disabled South Africans’ stereotypes concerning persons with physical disabilities

Abstract

The present paper examines stereotyping in relation to physical disability and gender in the South Africa. Cross-sectional data for the present study were gathered using free response items in a large survey (n = 1990) examining the attitudes of people without disability towards different facetsof sexuality and disability. The most prominent stereotypes found in thepresent study were those which characterised PWPD as withdrawn and shy, SuperCrips, or happy, funny, and kind. The findings in the present papersuggest that stereotypes of PWPD are not overwhelmingly de-sexualising, but are undifferentiated by gender.     

Disabling Africa: the power of depiction and the benefits of discomfort

Despite the fact that the vast majority of disabled people live in low and middle-income countries, the field of disability studies is dominated by research on disability in wealthy contexts. Although there are encouraging signs of this pattern changing, there are challenges to researchers about how to represent and think about disability in African contexts, and it is difficult not to reproduce unhelpful stereotypes. We use the example of an encounter we had with an expatriate Deaf South African to reflect on the complexities of representation facing people working on disability issues in Africa and what has been termed the Global South. We suggest that an appreciation of the productive value of discomfort about issues of representation may help move the field forward.     

WELFARE AND CITIZENSHIP: The Effects of Government Assistance on Young Adults' Civic Participation

Recent scholarship and public discourse highlight an apparent waning of civic engagement in the United States. Although the welfare state is generally thought to support democracy by reducing economic inequality, it may paradoxically contribute to political disempowerment of some groups. We examine the effects of state interventions on civic participation among young adults, hypothesizing that involvement with stigmatizing social programs, such as welfare, reduces political engagement, while receipt of nonstigmatizing government assistance does not dampen civic involvement. Using official voting records and survey data from the Youth Development Study (YDS), a longitudinal community sample of young adults, a series of regression models suggests that welfare recipients are less likely to vote than nonrecipients, whereas recipients of non-means-tested government assistance participate similarly to young adults who do not receive government help. These effects hold even when background factors, self-efficacy, and prior voting behavior are controlled. Welfare receipt is not associated, however, with suppressed participation in nonstate arenas such as volunteer work. Intensive interviews with YDS welfare recipients are used to illustrate and develop the analysis.

Extended voting measures

This paper extends a number of voting measures used to quantify voting power. The extension is based on the recognition that individuals sometimes vote in coalitions. This observation gives rise to a statistical model which considers past voting patterns of subsets of eligible voters. The model is then used to obtain estimates of the probabilities of all voting combinations from which empirical measures are calculated. The calculation of the estimated probabilities may involve high-dimensional integrations. An example is given based on past decisions arising from the Supreme Court of Canada.     

Experiences of visually impaired students in higher education: bodily perspectives on inclusive education

Although previous literature sheds light on the experiences of visually impaired students on tertiary grounds, these studies failed to provide an embodied understanding of their lives. In-depth interviews with 15 visually impaired students at one university demonstrated the ways in which they experienced their disability and the built environment in their bodies. At the same time, lost, fearful, shameful and aching bodies revealed prevailing gaps in provision for disabled students. Through this research it becomes clear how the environment is acutely felt within fleshly worlds, while bodies do not fail to tell of disabling societal structures. Based on the bodily stories, we thus make recommendations to improve the lives of visually impaired students on tertiary campuses.
