Normative approaches to justice in physical education for pupils with physical disabilities – dilemmas of recognition and redistribution

Seeking social justice in education for pupils with disabilities creates certain dilemmas. A ‘school for all’ means that educators are faced with the dilemma whereby the notion of ‘disability’ is perceived as ought not to matter but where in actual fact it seems to matter very much! This article explores ways out of this general educational dilemma using the context of physical education (PE) for pupils with physical disabilities within the compulsory school as an example. Justice theories of resource distribution and cultural recognition affect educational outcomes, where the demand is for justice and equity. Fraser’s notion of ‘social status’, together with a pluralistic approach to identities where personal experiences are given a place, is used to suggest a solution to the dilemma. It is concluded that a redistribution of economic resources and social recognition is necessary if social justice within PE is to become a reality.     

Modeling Transition Rates Using Panel Current-Status Data: How Serious is the Bias?

Studies of disability dynamics and active life expectancy often rely on transition rates or probabilities that are estimated using panel survey data in which respondents report on current health or functional status. If respondents are contacted at intervals of one or two years, then relatively short periods of disability or recovery between surveys may be missed. Much published research that uses such data assumes that there are no unrecorded transitions, applying event-history techniques to estimate transition rates. In recent years, a different approach based on embedded Markov chains has received growing use. We assessed the performance of both approaches, using as a criterion their ability to reproduce the parameters of a “true” model based on panel data collected at one-month intervals. Neither of the widely used approaches performs particularly well, and neither is uniformly superior to the other.     

The Social and Psychological Impacts of Gambling in the Cree Communities of Northern Québec

A detailed survey of gambling, addiction and mental health was conducted with randomly selected respondents (n = 506) from four Cree communities of Northern Quebec. The study examined the current patterns of gambling in relation to demographic, social, and psychological factors. Instruments included the Canadian Problem Gambling Index, Addiction Severity Index, Beck Depression Inventory and the computerized Diagnostic Interview Schedule for psychiatric diagnoses. Overall, 69.2 % of the total sample participated in any gambling/gaming activities over the past year; 20.6 % of this group were classified as moderate/high risk gamblers, and 3.2 % were classified in the highest “problem gambling” category. Considering the entire sample, the overall prevalence of problem gambling was 2.2 %. Women were significantly more likely to play bingo (56.6 %) compared to men (35.1 %) and they played more frequently; 20.8 % of women versus 3.8 % of men played once/week or more often. Compared to the no/low risk gamblers, a greater proportion of moderate/high risk gamblers were cigarette smokers (44.8 vs. 56.3 %), they were more likely to meet DSM-IV diagnostic criteria for alcohol dependence (21.2 vs. 46.2 %), and they were more likely to report moderate to severe depressive symptoms in the past month. Risk factors for problem gambling included traumatic life events (physical and emotional abuse), anxiety and depression, as well as drug/alcohol abuse. The high rates of comorbidity between problem gambling, tobacco dependence, substance abuse and other psychological problems demonstrate that gambling among some Cree adults is part of a pattern of high-risk factors for negative long-term health consequences. The results also have implications for treatment, suggesting that interventions for gambling disorders should not focus on gambling alone but rather the constellation of high-risk behaviours that pose a risk to recovery and well-being.

A Multiple Three-Decision Procedures for Comparing Several Treatments with a Control Under Heteroscedasticity

In this article, the design-oriented two-stage multiple three-decision procedure is proposed to classify a set of normal populations with respect to a control under heteroscedasticity. The statistical tables of percentage points and the power-related design constants, to implement our new two-stage procedure, are given. Sometimes when the sample for the second stage is not available, the one-stage data analysis procedure is proposed. Classifying a treatment better than control when it is actually worse (and vice versa) is known as type III error. Both the two-stage and one-stage procedures control the type III error rate at a specified level. The relationship between the two-stage and one-stage procedures is discussed. Finally, the application of the proposed procedures is illustrated with an example.     

Anna Karenina and the two envelopes problem

The Anna Karenina principle is named after the opening sentence in the eponymous novel: Happy families are all alike; every unhappy family is unhappy in its own way. The two envelopes problem (TEP) is a much-studied paradox in probability theory, mathematical economics, logic and philosophy. Time and again a new analysis is published in which an author claims finally to explain what actually goes wrong in this paradox. Each author (the present author included) emphasises what is new in their approach and concludes that earlier approaches did not get to the root of the matter. We observe that though a logical argument is only correct if every step is correct, an apparently logical argument which goes astray can be thought of as going astray at different places. This leads to a comparison between the literature on TEP and a successful movie franchise: it generates a succession of sequels, and even prequels, each with a different director who approaches the same basic premise in a personal way. We survey resolutions in the literature with a view to synthesis, correct common errors, and give a new theorem on order properties of an exchangeable pair of random variables, at the heart of most TEP variants and interpretations. A theorem on asymptotic independence between the amount in your envelope and the question whether it is smaller or larger shows that the pathological situation of improper priors or infinite expectation values has consequences as we merely approach such a situation.
