The Recent Mortality Decline in Russia: Beginning of the Cardiovascular Revolution?

The health situation in Russia has often been characterized as a long‐running crisis. From the 1960s until the beginning of the 2000s, the declining life expectancy trend was substantially interrupted only twice: once in the mid‐1980s as a result of Gorbachev's anti‐alcohol campaign, and again at the end of the 1990s as a result of the “rebound” effect following the dramatic rise in mortality associated with the acute socioeconomic crisis. In both cases, the progress made proved to be short‐lived. A third mortality decline in Russia began in 2003 and is still ongoing. We investigate the components and driving forces of this new development, in particular the role played by cardiovascular diseases. Using cause‐specific mortality data, we identify the main features of the recent improvements and compare these features with those observed in selected European countries, specifically France, Poland, and Estonia. Our aim is to gauge whether the features of the improvements in these countries are similar to those of the recent advancements made in Russia. Although the recent improvements in Russia have features in common with initial stages of prior mortality declines in other countries and may support optimism about the future, a return to mortality stagnation cannot be ruled out.     

Do male and female gamblers have the same burden of adversity over their life course?

The objective of this research is to investigate gender difference and the burden of adversity during the life course of people who develop gambling problems. A sample of 86 adult participants met the criteria for at-risk problem gambling over the last 5 years. Data were obtained from informants during semi-structured face-to-face interviews, using SCID I and II, SOGS, Module K and a recount of life trajectories methodology. The results showed a high level of adversity throughout the life trajectories of the men and women studied. The results indicated that the major load of mental health disorders, the presence of anxiety disorders and co-morbid mental health disorders are more significant among women. Results also indicated a significant presence of violence in the lives of both men and women during early childhood and adolescence. During adulthood, women are more likely to be victims of intimate partner or marital violence whereas men tended to cumulate difficulties in social fields and especially in their professional lives. This significant burden of adversity creates a number of difficulties which makes it complicated to isolate gambling activities. Clinicians might have difficulty detecting female gamblers during consultation, especially when they present with co-morbid mental health disorders and violence issues.     

Activism Among Older Women in Quebec,Canada: Changing the World After Age 65

ABSTRACT

The aim of this article is to examine senior women's involvement experience in Quebec, Canada. Study results are based on a qualitative methodology, and shed light on family history and continuity in the involvement trajectory, diversity in terms of group type and involvement practices, and gender differences in involvement. The meaning that older women attribute to their involvement is also addressed, including attitudes toward feminism. The discussion highlights the extent to which older women's involvement has been marked by their life trajectories, above and beyond their age. In sum, their involvement in the private and public spheres is quite impressive.     

Model-based clustering of multivariate ordinal data relying on a stochastic binary search algorithm

We design a probability distribution for ordinal data by modeling the process generating data, which is assumed to rely only on order comparisons between categories. Contrariwise, most competitors often either forget the order information or add a non-existent distance information. The data generating process is assumed, from optimality arguments, to be a stochastic binary search algorithm in a sorted table. The resulting distribution is natively governed by two meaningful parameters (position and precision) and has very appealing properties: decrease around the mode, shape tuning from uniformity to a Dirac, identifiability. Moreover, it is easily estimated by an EM algorithm since the path in the stochastic binary search algorithm can be considered as missing values. Using then the classical latent class assumption, the previous univariate ordinal model is straightforwardly extended to model-based clustering for multivariate ordinal data. Parameters of this mixture model are estimated by an AECM algorithm. Both simulated and real data sets illustrate the great potential of this model by its ability to parsimoniously identify particularly relevant clusters which were unsuspected by some traditional competitors.     

Monopolistic Competition: Beyond the Constant Elasticity of Substitution

We propose a model of monopolistic competition with additive preferences and variable marginal costs. Using the concept of “relative love for variety,” we provide a full characterization of the free‐entry equilibrium. When the relative love for variety increases with individual consumption, the market generates pro‐competitive effects. When it decreases, the market mimics anti‐competitive behavior. The constant elasticity of substitution is the only case in which all competitive effects are washed out. We also show that our results hold true when the economy involves several sectors, firms are heterogeneous, and preferences are given by the quadratic utility and the translog.     

Multiple criteria decision analysis of treatment and land-filling technologies for waste incineration residues

In this paper, we present a real-world case realized in Switzerland on behalf of the federal agency in charge of the waste policy. The incineration of urban wastes generates hazardous residues that need specific treatment and/or land-filling technologies. The variety of local situations and appraisals led to the choice of very different solutions. Moreover, proponents were keen to propose new technologies. The purpose of this study was to provide the background for a national policy that would apply to all future projects.     

The impact of language and culture on perceived website usability

Online retailers offering their products across national and cultural borders are eager to enhance the usability of their websites to attract large numbers of visitors. The results of the present research show that the perceived usability increases when the website was originally conceived in the native language of the user. Thus, translation, even though of excellent quality, creates a cultural distance which impacts on the web users’ evaluation of the site. Conversely, where language is less important, such as in the evaluation of the quality of an offer, a consumer's native language has no impact on the buying decision.
