The effectiveness of Luxembourg's minimum guaranteed income

Using micro‐data for the year 2007, this article analyzes the effectiveness of Luxembourg's minimum guaranteed income (revenu minimum garanti — RMG) social assistance programme. First, we examine the effectiveness of the RMG by comparing the proportion of eligible households based on the different criteria for the years 2007 and 1986, and find that, in 2007, 5.5 per cent of households were eligible versus 3.75 per cent in 1986. A relaxation of the RMG's eligibility criteria implies that more low‐income households should have access to the RMG. As a second measure of programme effectiveness, the article estimates the extent of non‐takeup behaviour among those eligible for the RMG in 2007. It is found that just over 65 per cent of all households potentially entitled to the RMG do not claim. Regression analysis of the potential determinants of non‐takeup behaviour confirms the hypotheses derived from theoretical models in the literature, i.e. that rational motivation, such as the expected net utility from claiming, and stigma, play a major role in explaining levels of non‐takeup.

Sing … Then Think: Musical Interventions and Nondeliberative Forms of Practice in Social Work Groups

ABSTRACT

The positive effects of music have been demonstrated worldwide in many fields including social work, psychology, medicine, and education. Musical interventions including music listening, lyric analysis, and singing have also been found effective in group work. This article, guided by Norma Lang’s nondeliberative theory, aims to provide the “why,” “when,” and “how” of incorporating music into social work groups. It also provides the reader with a toolbox of musical interventions and the encouragement to utilize these “artful, actional, and analogic” activities in group work.     

Statistical analysis of rank data from a visual matching of colored textures

Nowadays, sensory properties of materials are subject to growing attention both in an hedonic point of view and in an utilitarian one. Hence, the formulation of the foundations of an instrumental metrological approach that will allow for the characterization of visual similarities between textures belonging to the same type becomes a challenge of the research activities in the domain of perception. In this paper, our specific objective is to link an instrumental approach of metrology of the assessment of visual textures with a metrology approach based on a softcopy experiment performed by human judges. The experiment consisted in ranking of isochromatic colored textures according to the visual contrast. A fixed effects additive model is considered for the analysis of the rank data collected from the softcopy experiment. The model is fitted to the data using a least-squares criterion. The resulting data analysis gives rise to a sensory scale that shows a non-linear correlation and a monotonic functional relationship with the physical attribute on which the ranking experiment is based. Furthermore, the capacity of the judges to discriminate the textures according to the visual contrast varies according to the color ranges and the textures types.     

Adapted Couple Therapy (ACT) for Pathological Gamblers: A Promising Avenue

The study of the effectiveness of treatment for pathological gambling constitutes a field that is still largely unexplored. To date, the models assessed primarily target the individual and include little or no involvement of the family circle. Yet, the deleterious effects of gambling on loved ones and especially spouses are well recognized. Further, the addition of a couple modality to individual treatment has been shown to be effective on many levels in the treatment of substances use disorders. This article therefore proposes a critical review of (1) the literature providing a better understanding of the complex interactions between the couple relationship and pathological gambling, (2) studies on the effects of couple therapies on gamblers and their partners. We then present the therapeutic model developed by our team of clinician-researchers in collaboration with actors from Québec clinical settings: Adapted Couple Therapy (ACT) for pathological gamblers. In the Québec context, this model will serve as a complement to an individual cognitive-behavioral treatment model that has been proven effective and is employed throughout the Canadian province. The assessment of couple therapies could reveal avenues of solutions to better assist pathological gamblers who tend to drop-out of treatment and relapse.     

Toward a comprehensive demography: rethinking the research agenda on change and response

This essay drafts a new interdisciplinary agenda for research on population and development. Starting from Kingsley Davis's 1963 formulation of change and response, Davis's analytical categories are broadened to include inertia as well as change and to encompass both demographic and non-demographic responses at the micro, meso, and macro levels. On that basis the essay proposes what can be called a comprehensive demography, an approach drawing principally on micro-level methodologies like those employed in anthropological demography. Like anthropological demography, comprehensive demography questions the rationality of actors, emphasizes cultural infuences, and stops short of the postmodernist extremes of anthropology. But it also takes explicit account of higher-level social, economic, and political factors bearing on demographic behavior and outcomes. The conclusion raises some epistemological issues. Illustrative examples are offered throughout to demonstrate the feasibility of the approach, mainly referring to sub-Saharan africa and the Caribbean and often drawn from the authors' own fieldwork.     

Maximum Likelihood Estimation of Discretely Sampled Diffusions: A Closed‐form Approximation Approach

When a continuous‐time diffusion is observed only at discrete dates, in most cases the transition distribution and hence the likelihood function of the observations is not explicitly computable. Using Hermite polynomials, I construct an explicit sequence of closed‐form functions and show that it converges to the true (but unknown) likelihood function. I document that the approximation is very accurate and prove that maximizing the sequence results in an estimator that converges to the true maximum likelihood estimator and shares its asymptotic properties. Monte Carlo evidence reveals that this method outperforms other approximation schemes in situations relevant for financial models.
