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. 相似文献

Sing … Then Think: Musical Interventions and Nondeliberative Forms of Practice in Social Work Groups
ABSTRACTThe 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. 相似文献

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. 相似文献

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. 相似文献

Maximum Likelihood Estimation of Discretely Sampled Diffusions: A Closed‐form Approximation Approach
Yacine Aït‐Sahalia 《Econometrica : journal of the Econometric Society》2002,70(1):223-262
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. 相似文献

Many studies carried out on treatment-seeking problem gamblers (PG) have reported high levels of comorbid substance use disorders, and mental and physical health problems. Nevertheless, general population studies are still sparse, most of them have been carried out in the United States or Canada, and gender differences have not always been considered. Thus, the aim of this study was to describe the type of games, and psychological and physical correlates in male and female PG in a nationally representative French sample. The total sample studied involved 25,647 subjects aged 15–85 years, including 333 PG and 25,314 non-problem gamblers (NPG). Data were extracted from a large survey of a representative sample of the French general population. They were evaluated for sociodemographic variables, gambling behavior, type of gambling activity, substance use, psychological distress, body mass index, chronic disease, and lack of sleep. Overall, there were significant differences between PG and NPG in gender, age, education, employment and marital status, substance use disorders (alcohol, tobacco, cannabis, cocaine and heroin), psychological distress, obesity, lack of sleep and type of gambling activity. Although male and female PG had different profiles, the gambling type, especially strategic games, appeared as an important variable in the relationship between gender and problem gambling. This research underlines the importance of considering gender differences and gambling type in the study of gambling disorders. Identifying specific factors in the relationship between gender, gambling type and gambling problems may help improve clinical interventions and health promotion strategies. 相似文献

While the average gender gap in pensions is quite well documented, gender differences in the distribution of pensions have rarely been explored. We show in this paper that pension dispersion is very similar for men and women within the French pension system of a given sector (public or private). Gender differences are less marked among retired civil servants than among former private sector employees. However, the determinants of these inequalities are not the same for men and women. Using a regression-based decomposition of the Gini coefficient, we find that pension dispersion is mostly due to dispersion of the reference wage for all retirees but gender differences exist. For women, in particular, pension dispersion is also due to the dispersion in contribution periods. We also decompose the Gini coefficient by source of pension to measure the impact of institutional rules (minimum pensions, survivor’s pension) on the extent of pension inequality. Unexpectedly, we find that the impact of minimum pensions is limited, although slightly larger for civil servants than for private-sector employees. Survivor’s pension schemes, on the other hand, contribute positively to pension dispersion among retired women. 相似文献
