Constitutional Reform and Canadian Social Policy

It is generally accepted that Governments, with a neo-conservative or more properly a Victorian neo-liberal bent will, through various means and mechanisms, try to dismantle aspects of the Welfare State. While these mechanisms usually take the form of privatization, reductions in expenditures, de-indexing and the like, a much more subtle process currently is underway in Canada. Two broad initiatives — Constitutional Change and Free Trade — of the Mulroney government seriously threaten the future of the Canadian Welfare State. The Welfare State is not the direct target in either of these initiatives but the implications, in the view of the authors, are profound. This article examines the question of constitutional reform and the consequences for Canadian social policy.

Transformations in social work: From help towards social inclusion to the management of exclusion

The debate about the forms of increasing social exclusion in the developed western industrialized nations is the starting-point of this paper. This is followed by a discussion of the possible and likely consequences of social exclusion for social work theory and practice. It is suggested that on the social-theoretical basis of Luhmanns Systems Theory, social work can be investigated as the practice of averting exclusion, facilitating inclusion, and the management of exclusion in functionally differentiated societies. Against this background it is argued that social work as a form of secondary protection, both theoretically and practically, has to be related to the modes of inclusion and exclusion of social systems and organizations. In order to provide a theoretical clarification of the social tasks and opportunities of social work it is therefore necessary to conduct a precise analysis of the structures, forms, and processes of social inclusion and exclusion. At present it seems likely that, because of general societal developments, the increasing extent of exclusion and the intensification of exclusionary effects will lead to a situation in which social work will be restricted to the function of the management of exclusion.     

Pseudo-bayes estimation of multinomial proportions

In the simultaneous estimation of multinomial proportions, two estimators are developed which incorporate prior means and a prior parameter which reflects the accuracy of the prior means. These estimators possess substantially smaller risk than the standard estimator in a region of the parameter space and are much more robust than the conjugate Bayes estimator with respect to parameter values far from the prior mean. When vague prior information is available, these estimators and confidence regions derived from them appear to be attractive alternatives to the procedures based on the standard estimator.     

Long- and short-term affective states in happiness: Model,paradigm and experimental evidence

The present paper evaluates relevant findings on long- and short-term affective states in subjective well-being and argues for a componential model that combines the two into the more general concept of happiness. Two age parameters, one for long-term and one for short-term affect are added to the simple model to account for age changes in happiness. Measures of long- and short-term affect are presented, as is a paradigm for separating the components. Support for the simple model is provided by an experimental investigation with 64 college students who were exposed to positive and/or negative mood induction. As expected, the induction had substantially greater effect on short- than on long-term affect measures, particularly the negative induction procedure. These findings are consistent with predictions. However, multiple age cohorts will have to be assessed within a longitudinal framework to obtain values for the age parameters.     

A bayesian test for a two-way contingency table using independence priors

One method of testing for independence in a two-way table is based on the Bayes factor, the ratio of the likelihoods under the independence hypothesis H and the alternative hypothesis H. The main difficulty in this approach is the specification of prior distributions on the composite hypotheses H and H. A new Bayesian test statistic is constructed by using a prior distribution on H that is concentrated about the “independence surface” H. Approximations are proposed which simplify the computation of the test statistic. The values of the Bayes factor are compared with values of statistics proposed by Gunel and Dickey (1974), Good and Crook (1987), and Spiegelhalter and Smith (1982) for a number of two-way tables. This investigation suggests a strong relationship between the new statistic and the p-value.
