The anti-social model of disability

Social theories are usually developed to enable a clearer understanding of a situation or problem. The 'Social Model' in various forms is currently the dominant model for researching disability, addressing disability from within a socio-political framework that draws substantially on a 'social constructionist' perspective. This article critiques some of the core sociological assumptions of the Social Model, questioning what 'work' this kind of theory does in informing a set of practical concerns around the design of assistive technologies, suggesting an alternative framework of analysis, supported by extensive ethnomethodologically informed ethnographic research     

EXPECTATIONS OF RATIOS OF QUADRATIC FORMS IN NORMAL VARIABLES: EVALUATING SOME TOP-ORDER INVARIANT POLYNOMIALS

Chikuse's (1987) algorithm constructs top-order invariant polynomials with multiple matrix arguments. Underlying it is a set of simultaneous equations for which all integer solutions must be found. Each solution represents a component of the sum of terms which comprise the polynomial. The system of equations has a specialised structure which may be exploited to obtain a polynomial with r matrix arguments in terms of a polynomial with r-1 matrix arguments. This is demonstrated for two particular polynomials that have two matrix arguments. These results are applied to problems involving expectations of ratios of quadratic forme in normal variables; analytic as well as computable formulae are derived.     

HOW INEFFICIENT ARE MULTIPLE IN-KIND TRANSFERS?

The inefficiencies from multiple in-kind transfers are smaller than one would guess from studying such programs singly, though Medicaid can give rise to average discounts as large as 60 percent. The benefits from the programs are quite large relative to recipients' incomes. Effective marginal tax rates under in-kind transfers are appreciably lower than they would be if the programs gave cash. Poverty rates among recipients are markedly lowered if one counts the value of in-kind transfers as income; this effect is insensitive to whether one accounts for the discounting of in-kind transfers by recipients.

Fishermens blues: Factors related to accidents and safety among Newfoundland fishermen

The fisheries is one of the most dangerous industries in Canada. Possible contributory causes of the high rate of injuries are a fatalistic attitude to accidents and safety, and a high level of anxiety and worry among fishermen. These characteristics would be expected to lead to less attention to safety procedures and a consequent greater risk of accidents. The purpose of this study was to explore fishermen's levels of fatalism and anxiety; to consider the relationship of these factors to the frequency of accidents and extent of safety precautions; and to explore fishermen's explanations of and suggested solutions to the high rate of injuries at sea. The study was conducted among a sample of inshore fishermen who fished in the waters around Newfoundland. Fifty-five fishermen completed a questionnaire that requested basic demographic details, information on injuries obtained, safety precautions taken, perceived locus of control over accidents, anxiety, worries and explanations for accidents and possible measures to reduce them. Analysis of their replies revealed that the fishermen reported a high level of anxiety and that those who reported most anxiety reported more injuries and fewer safety precautions.     

Residential House and Zone Volumes in the United States: Empirical and Estimated Parametric Distributions

This research reports empirical distributions and estimated univariate parametric probability distributions for house volume and certain zone volumes within households for residential structures in the United States. The author derived the distributions from two separate databases. The volumes were found to be exceptionally well fit by lognormal distributions (adjusted R² >> 0.95) in almost all cases. In addition, data from one database indicates that the correlation between house volume and air changes per hour is very weak.     

Negotiating Interactions in State�CVoluntary Sector Relationships: Competitive and Collaborative Agency in an Experiential Workshop

This article examines an experiential student workshop focused on state?Cvoluntary sector relationships in the UK, which formed part of a postgraduate voluntary sector studies programme. The different group behaviours observed were instructive in illustrating how students, all working in third sector or related public agencies, perceive and have assimilated demands and practices of the external environment. These insights also highlight the value of experiential learning in higher education both for student reflection and research. The article adopts an interdisciplinary approach to examine some consequences of ideologies and behaviours associated with managerial culture permeating actions in this interactive setting. It combines critical discussion of non-profit organizations with group relations and learning theories, offering a different perspective through which to explore patterns embedded in inter-agency relationships. Consideration of ways that these patterns might be changed to improve the service environment in the voluntary sector has wider implications for research in this field.     

ESTIMATING THE STOCK‐FLOW MATCHING MODEL USING MICRO DATA

We estimate the stock‐flow matching model using micro‐level data from a well‐defined labor market. Using a dataset of complete labor‐market histories for both sides of the market, we estimate hazard functions for job‐seekers and vacancies. We find that the stock of new vacancies has a significant positive impact on the job‐seeker hazard, over and above that of the total stock of vacancies. There is an even stronger robust result for vacancy hazards. Thus we find evidence in favor of stock‐flow matching, even when controlling for unobserved search heterogeneity and stratifying into submarkets defined by location and occupation.     

Change in the stressfulness of life in American states and regions from 1976 to 1982

The State Stress Index (SSI) described in this paper^I measures difference between the states of the United States, and differences over time, in the occurrence of stressful life events. The method of constructing the SSI is described and the scores for each of the American states in 1976 and 1982 are presented. There are large differences between the states in the stressfulness of life. The construct validity of the SSI was supported by analysis which show that the higher the SSI, the higher the incidence of behaviors that have long been assumed to be affected by stress, such as violence and heavy smoking and drinking, and suicide. Scores on the SSI revealed an increase in the stressfulness of life between 1976 and 1982, largely due to the economic recession in 1982. Despite this the 1982 rank order of the states was essentially the same as their relative position in 1976. The West remained the most stressful region of the United States, despite its other attractions, and the North Central and North East remained the least stressful regions, despite their rustbelt and frostbelt images.     

The Epidemiologic Transition Revisited: Compositional Models for Causes of Death by Age and Sex

For decades, researchers have noted systematic shifts in cause‐of‐death patterns as mortality levels change. The notion of the “epidemiologic transition” has influenced thinking about the evolution of health in different societies and the response of the health system to these changes. This article re‐examines the epidemiologic transition in terms of empirical regularities in the cause composition of mortality by age and sex since 1950, and considers whether the theory of epidemiologic transition presents a durable framework for understanding more recent patterns. Age‐sex‐specific mortality rates from three broad cause groups are analyzed: Group 1 (communicable diseases, maternal and perinatal causes, and nutritional deficiencies); Group 2 (noncommunicable diseases); and Group 3 (injuries), using the most extensive international database on mortality by cause, including 1,576 country‐years of observation, and new statistical models for compositional data. The analyses relate changes in cause‐of‐death patterns to changing levels of all‐cause mortality and income per capita. The results confirm that declines in overall mortality are accompanied by systematic changes in the composition of causes in many age groups. These changes are most pronounced among children, for whom Group 1 causes decline as overall mortality falls, and in younger adults, where strikingly different patterns are found for men (shift from Group 3 to Group 2) compared to women (shift toward Group 2 then Group 3). The underlying patterns that emerge from this analysis offer insights into the epidemiologic transition from high‐mortality to low‐mortality settings.
