A unified approach to multilevel sample selection models

Abstract

We propose a unified approach for multilevel sample selection models using a generalized result on skew distributions arising from selection. If the underlying distributional assumption is normal, then the resulting density for the outcome is the continuous component of the sample selection density and has links with the closed skew-normal distribution (CSN). The CSN distribution provides a framework which simplifies the derivation of the conditional expectation of the observed data. This generalizes the Heckman’s two-step method to a multilevel sample selection model. Finite-sample performance of the maximum likelihood estimator of this model is studied through a Monte Carlo simulation.     

Mortality analysis of persons with disabilities in Argentina by age,sex and duration of benefit, 2015–16

This article describes the differential mortality of Argentina’s disability pension beneficiaries during the 2015–16 period, based on National Social Security Administration (Administración Nacional de la Seguridad Social – ANSES) payment records. It compares data for those with an assessed disability with overall population data, as well as with available international data (from Canada, Chile, Mexico, and the United States of America). In addition to breaking down mortality rates for people with disabilities by age and sex, it also factors in duration of benefit, establishing an inverse correlation between benefit duration and mortality.     

Enabling everything: scale,disability and the film The Theory of Everything

This article looks at the representation of scale in the 2014 film The Theory of Everything, identifying moments that relate to three concerns: firstly, how disabled people experience scale issues at an all too practical level in daily life; secondly, how Hawking’s experience of scale at the level of both body and mind is (a)typical of the way it is experienced by disabled people generally; and, thirdly, how a focus on the film can prompt some rethinking of perspectives both within disability studies and within the conceptualisation of scale more broadly.     

Disabled or differently-enabled? Dyslexic identities in online forum postings

This study presents a novel exploration into how people with dyslexia construct personal identities within anonymous, unsolicited, postings to an online discussion forum. An interpretational phenomenological analysis suggested three key identities: learning-disabled, differently-enabled and societally-disabled. These are discussed in terms of the extent to which they draw differentially on a discourse of disability as opposed to one of individual difference. The identities are to an extent malleable and overlapping according to context. Postings suggested overall that while some contributors constructed themselves as differently-enabled and celebrated dyslexia-related abilities, others sensed themselves having a disabled identity imposed upon them. Dyslexia is perceived as negatively construed within a society which promotes literacy and cognitive acuity as essential aspects of educational and social competence and where learning differences are poorly tolerated. In addition, this study highlights the potential of online forum contributions in the study of social influences in under-researched groups.     

Gender,technology and the ablenational Paralympic body politic

ABSTRACT

The Paralympic games is a pedagogic, pervasive, political, powerful, and ‘popular’ cultural site where the heightened visibility of disability bring into being specific forms of disability as they articulate within cultures, institutions and practices. Regarded as a ‘positive charge’ by Stuart Hall, the Paralympics intends to challenge the devalued disabled body politic of typical disability representation. This has been stimulated by the entry of Channel 4 as the UK Paralympic rights holders in 2012 which has seen greater media coverage of certain technologically enhanced cyborgian parasport bodies and an emerging celebrity / sexualized disability culture. This contemporary moment in disability representation provides a compelling space in which to (re-)address the gendered nature of hyper-visible Parasport hybrids, their potential to disrupt ‘normative’ relations of power, and, the wider impact on disability politics in a neoliberalised culture of widening and affective circuits of bodily inclusion and control. Drawing on an integrated content and textual analysis of 90?h of Paralympic programming from the Rio 2016 Games we highlight two emblematic segments so as to enhance our appreciation of contemporary disabled politics as it intersects with gender, technology and nation. We analyse these emblematic segments at the intersection of critical disability studies, cultural studies and sport, using concept of ablenationalism to highlight the extent certain technological capacitated parasport bodies perform gendered representational work as part of the seductive apparatus of neoliberal micro-governance suggestive of an emerging ecology of disability-gender relations. In doing so, we highlight the Paralympic contradictions and interrogate the assumed ‘positive charge’ of the contemporary (re-)presentation of disability.     

Is emergency preparedness a ‘disaster’ for people with disabilities in the US? Results from the 2006–2012 Behavioral Risk Factor Surveillance System (BRFSS)

This study compared emergency preparedness of people with activity limitations, with limitations who use specialized equipment, and with mental health conditions with that of people without these disabilities. Results of chi-square analysis and logistic regression analysis showed that people with activity limitations and/or mental health conditions were significantly less prepared for emergencies than people who used specialized equipment or persons without disabilities. Having an activity limitation and/or severe mental health conditions, and being non-white, uncoupled, female, and below the poverty line increases the likelihood of not being prepared. Suggestions for increasing preparedness related to training and policy development were discussed.     

The Principles and Ethics of Including Children with Disability in Child Research

This paper provides a set of principles and ethics, developed in collaboration between Pacific‐ and Australian‐based researchers, to guide research practice in a project enabling the self‐reporting of children with disability in Vanuatu and Papua New Guinea (PNG). The paper presents both a summary of academic literature relating to these principles and ethics, as well as their succinct ‘translation’ into a set of action statements for researchers working with children with disability. The paper offers a base for further development by others to guide research practice and foster the autonomous participation of children with disability in developing countries.     

From comedy targets to comedy-makers: disability and comedy in live performance

The stand-up comedy landscape has been transformed in recent years with an increased number of disabled comedians performing. Using semi-structured interviews with disabled comedians, this article provides a thematic analysis of the material and ideological motives, intentions and lived experiences of disabled comedians. Two themes are discussed: comedy management and control; and affirming disability through comedy. These themes are characterised by complexity and contradictions. The article concludes that, although not a straightforward process, stand-up comedy enacted by disabled comedians is potentially a powerful tool through which hegemonic norms around disability can be challenged and renegotiated.     

‘I nearly lost my work’: chance encounters,legal empowerment and the struggle for disability rights in Ghana

This article uses a case study from Ghana to argue that rights-based legal instruments are important but insufficient steps towards securing disability rights in non-western societies. Despite Ghana’s implementation of a Disability Act and ratification of the United Nations Convention on the Rights of Persons with Disabilities, a grassroots perspective shows that legislation and the model of legal empowerment will not automatically produce equal access to human rights. The paper will present this argument through a case study of an individual who became disabled in 2008 and struggled for four years to secure his rights to healthcare and employment. I also argue that the case has a wider significance for disability rights in Ghana and beyond.     

Navigating the ethical maze in disability research: ethical contestations in an African context

Despite changes in how disability is viewed, ethical requirements for disability research have hardly changed. Some ethical clearance procedures, processes and practices still consider persons with disabilities as not able, creating unease among researchers and research participants with disabilities themselves. This paper considers five ethical contestations arising from research in the area of disability in an African context: positionality, vulnerability, signed consent, anonymity, and research committee composition. We argue that ethical requirements in practice are still largely based on a medical model of disability and propose that culturally sensitive social and human rights models should influence disability research ethics.
