Dialogues or polemics: Social science expertise and welfare reform in Quebec

The development of social assistance and poverty reduction policies has been informed by social scientific knowledge. Social scientists, however, are not of one mind on such matters. They tend to be divided along disciplinary and ideological lines and may even foster political divisions and conflicts. This article draws on the author's experience as an academic policy adviser to the Quebec government to analyse from up close the institutional context that facilitates knowledge utilisation in the policy process. Two reform processes are considered: the first one, between 1995 and 1998, was less collaborative and led to divisions, and the second, between 1997 and 2009, involved more interactions with the civil service and proved more fruitful. In both cases, experts were divided, as were politicians and civil servants, but their capacity to reach a consensus was fostered, in the second case, by better support and collaboration from the government.     

Invariant tests based on M-estimators,estimating functions,and the generalized method of moments

We study the invariance properties of various test criteria which have been proposed for hypothesis testing in the context of incompletely specified models, such as models which are formulated in terms of estimating functions (Godambe, 1960) or moment conditions and are estimated by generalized method of moments (GMM) procedures (Hansen, 1982), and models estimated by pseudo-likelihood (Gouriéroux, Monfort, and Trognon, 1984b,c) and M-estimation methods. The invariance properties considered include invariance to (possibly nonlinear) hypothesis reformulations and reparameterizations. The test statistics examined include Wald-type, LR-type, LM-type, score-type, and C(α)?type criteria. Extending the approach used in Dagenais and Dufour (1991), we show first that all these test statistics except the Wald-type ones are invariant to equivalent hypothesis reformulations (under usual regularity conditions), but all five of them are not generally invariant to model reparameterizations, including measurement unit changes in nonlinear models. In other words, testing two equivalent hypotheses in the context of equivalent models may lead to completely different inferences. For example, this may occur after an apparently innocuous rescaling of some model variables. Then, in view of avoiding such undesirable properties, we study restrictions that can be imposed on the objective functions used for pseudo-likelihood (or M-estimation) as well as the structure of the test criteria used with estimating functions and generalized method of moments (GMM) procedures to obtain invariant tests. In particular, we show that using linear exponential pseudo-likelihood functions allows one to obtain invariant score-type and C(α)?type test criteria, while in the context of estimating function (or GMM) procedures it is possible to modify a LR-type statistic proposed by Newey and West (1987) to obtain a test statistic that is invariant to general reparameterizations. The invariance associated with linear exponential pseudo-likelihood functions is interpreted as a strong argument for using such pseudo-likelihood functions in empirical work.     

The Development of a “Neighborhood in Solidarity” in Switzerland

ABSTRACT

This article presents a case study based on the “Neighborhood in Solidarity” (NS) methodology to illustrate its application in a locality of 8,000 inhabitants in Switzerland. This specific project is proposed to exemplify the global aim of the NS methodology. That aim is to increase the integration of elderly persons in societies in order to improve their quality of life. The case study demonstrates the enhancement of the capacity of the older people to remain actively engaged in their neighborhood. The article focuses on the creation of an autonomous community of empowered older people who can resolve their own problems after a 5-year project. The construction of the local community is presented throughout the six steps of the methodology: (1) preliminary analysis, (2) diagnostic, (3) construction, (4) project design, (5) project implementation, and (6) empowerment and with three degrees of involvement (community, participative, and integrative involvement). Performance and output indicators, quality indicators, and social determinants of health assess the development of the local project. The impacts of the projects which are illustrated in this specific example motivated this publication to inspire practitioners from other countries.     

Regional Integration,Multinational Enterprise Strategy and the Impact of Country‐level Risk: The Case of the EMU

The European Monetary Union (EMU) provides a new macro‐level, institutional setting for multinational enterprises (MNEs). The authors investigate the impact of regional integration on MNE strategy by analysing Belgian firms’ entry‐mode choices in foreign markets, both EMU and non‐EMU ones, with a focus on what impact remains of country‐level risk. They demonstrate that regional integration has altered the impact of country‐level institutional risk on MNE entry‐mode choices inside the EMU. The conventional predictions of international business theory have been reversed, with higher country‐level risk inside the EMU driving a preference for wholly owned subsidiaries. Within the integrated region, insider firms now view higher country‐level risk as the equivalent of higher, micro‐level contracting risk. Such risk can best be mitigated through full internalization, combined with arm's length contracts, rather than through equity joint ventures.     

An automatic robust Bayesian approach to principal component regression

Principal component regression uses principal components (PCs) as regressors. It is particularly useful in prediction settings with high-dimensional covariates. The existing literature treating of Bayesian approaches is relatively sparse. We introduce a Bayesian approach that is robust to outliers in both the dependent variable and the covariates. Outliers can be thought of as observations that are not in line with the general trend. The proposed approach automatically penalises these observations so that their impact on the posterior gradually vanishes as they move further and further away from the general trend, corresponding to a concept in Bayesian statistics called whole robustness. The predictions produced are thus consistent with the bulk of the data. The approach also exploits the geometry of PCs to efficiently identify those that are significant. Individual predictions obtained from the resulting models are consolidated according to model-averaging mechanisms to account for model uncertainty. The approach is evaluated on real data and compared to its nonrobust Bayesian counterpart, the traditional frequentist approach and a commonly employed robust frequentist method. Detailed guidelines to automate the entire statistical procedure are provided. All required code is made available, see ArXiv:1711.06341.     

Sustainability Ranking for Cuban Tourist Destinations Based on Composite Indexes

This investigation approaches the levels and the predictors of loneliness among migrant youths from returned migrant families from France to Portugal. Three research questions guided the study: (1) Does loneliness of migrant youths differ from those who have never migrated? (2) Are migrant youths’ re-acculturation factors related to their loneliness? (3) Is the adaptation of migrant youths linked to their loneliness? The answer to these questions is important to improve migrant youths’ re-acculturation experiences and their adaptation. The sample included 222 youths from returned migrant families from France. Participants completed the brief Portuguese version of the Revised UCLA Loneliness Scale (ULS-6), in addition to measures of re-acculturation and adaptation. A control group comprised of 211 Portuguese adolescents who have never migrated was also involved in the investigation. Youths from returned migrant families showed lower levels of loneliness than their native Portuguese counterparts who have never migrated. Demographic, re-acculturation, and adaptation factors were significantly related to adolescents’ loneliness. Major predictors of loneliness were age at return, contacts with peers without migratory experience, perceived discrimination, stressful adaptation experience, and satisfaction with life.     

Consistency between tastes and values: A universalization approach

The object of this paper is to propose a consistency test for an individual involved in collective choice process. Collective choice processes considered in the paper are those that transform individuals ‘tastes’– which reflect the self-interested view point of the individuals – into (social) ranking of alternatives. In addition to her tastes, an individual has values about the way by which collective decision should be made. We distinguish two categories of such values. First, there are end-values that restrict the class of social rankings that the individual considers ethically acceptable. Second there are aggregation-values that specify the way by which the social ranking should depend upon the individuals tastes. The consistency test stands on an hypothetical operation of universalization of the individual tastes to everyone. Five illustrations of the potential usefulness of our approach for interpreting social choice theory and welfare economics are proposed. These illustrations deal with utilitarian aggregation in the presence of income inequality aversion, the so-called ‘ethics of responsibility’ and the aggregation of individual ranking of opportunity sets based on their freedom of choice. A discussion of the relevance of the consistency test for addressing the problem of ‘laundering’ individual preferences is also provided. Received: 25 June 1998/Accepted: 16 March 1999     

Transformations in the medicalization of sex: HIV prevention between discipline and biopolitics

This article examines transformations in HIV prevention strategies from the 1980s to the present. Drawing on the concepts of medicalization (Conrad, 2007 ), discipline and biopolitics (Foucault, 1976/ 1988 ), and biomedicalization (Clarke, Fishman, Fosket, Mamo, & Shim, 2003 ), it explores the shift from behavioral to biomedical and surgical prevention techniques-a shift symbolic of a more general trend toward the biomedicalization of sexuality. It argues that, although biomedical and surgical approaches (chemoprevention and male circumcision) have certain benefits, their efficacy is limited and uncertain. They do not guarantee individual protection. The aim is no longer the modification of sexual behavior through disciplinary strategies aimed at the development of subjective and sexual awareness, but the modification of health behavior as a positive response to biomedical recommendations. Through the use of preventative or curative drugs, the same type of sexual awareness is seen as no longer required.     

Sexology in Portugal: Narratives by Portuguese Sexologists

This article presents the emergence and development of modern sexology in Portugal through the analysis of Portuguese sexologists’ narratives, to explore how they commit to a professional identity as sexologists, and to discuss how they integrate their professional role into the vast multidisciplinary field of sexology. In-depth interviews were conducted with 44 key professionals, purposefully recruited to guarantee heterogeneity concerning generation, gender, training, and practice. Content analysis focused on highlighting differences and articulations among the main professionals making up the field. The findings indicate that sexology is not seen as a full-fledged profession but rather as a specialization or a secondary field of action. The sexual medicine perspective is prevalent and more visible among physicians, thus reflecting the gap between psychosocial and biomedical approaches. A close link between clinical work and research and a gap between clinical work and health promotion were found. Despite the multidisciplinary nature of sexology being acknowledged, it is not fully implemented by the experts in the field. However, it is this characteristic that permitted sexology to institutionalize and to legitimate itself as a discourse of truth about sex, in Portugal as in other countries.
