Classification of Gamblers According to the NODS and a Clinical Interview1

Since the social and personal implications of excessive gambling are important, it becomes necessary to assess the extent of the problem within the population. Accordingly, the use of an instrument that evaluates gamblers accurately is essential. This study, carried out with 200 adults, investigates the potential differences in classification of gamblers when using the NORC DSM-IV Screen for gambling problems (NODS) versus a clinical interview. The results show that 50 of the 200 participants were not categorised in the same way with the NODS as with the clinical interview; 47 participants were identified as having a more severe gambling problem according to the NODS than with the clinical interview, providing a 23.5% difference in the concordance rate. This result is discussed in terms of measurement problems in assessing gambling behaviours.     

Functional data: local linear estimation of the conditional density and its application

In this paper, we introduce a new nonparametric estimation procedure of the conditional density of a scalar response variable given a random variable taking values in a semi-metric space. Under some general conditions, we establish both the pointwise and the uniform almost-complete consistencies with convergence rates of the conditional density estimator related to this estimation procedure. Moreover, we give some particular cases of our results which can also be considered as novel in the finite-dimensional setting. Notice also that the results of this paper are used to derive some asymptotic properties of the local linear estimator of the conditional mode.     

International Women's Day: Art project for young women

Abstract

The primary aim of the project was to provide the opportunity for a marginalised group of young women to participate in International Women's Day with other women and members of the community and to have the opportunity to express themselves and aspects of their lives in art work on ceramic platters. The target group were ‘homeless, transient and at risk young women from 18 to 25 years of age, including Koori women’, engaged mainly through local homeless youth agencies in the Port Phillip area in Victoria. It was thought that many of this target group had been left out of formal support service provision. The project was evidently a success, both in terms of its modest aims and, most importantly, as evaluated by the participants themselves. Those interviewed expressed greater feelings of social connectedness - particularly with other women, raised self esteem and optimism and a new found enjoyment in the creative process.     

Mortality in Belarus, Lithuania, and Russia: Divergence in Recent Trends and Possible Explanations

Before the collapse of the Soviet Union, Belarus, Lithuania, and Russia were quite comparable in terms of their socioeconomic development. Despite some differences in overall mortality levels, the three former Soviet republics were also very close to each other in terms of directions of mortality trends and age- and cause-specific mortality patterns. After 1991, all the three countries experienced substantial political and social transformations, and the challenges associated with the transition from a socialist to a market economy system. The sudden changes brought numerous problems, such as rapid growth in unemployment, falling standards of living, and growing social and income inequalities. These factors contributed to the significant deterioration of the health situation in all the countries, but the size and the nature of the mortality crisis was different in Belarus than it was in Lithuania and Russia. The marked similarities in socioeconomic and mortality trends in the countries up to 1991 contrast with their notable divergence during the subsequent years. The nature and success of market reforms seems to be the most plausible explanation for these differences. Russia and Lithuania have chosen more radical forms of economic and political transformations, which have led to massive privatization campaigns. The reforms were more sustainable and systematic in Lithuania than in Russia. By contrast, Belarus has chosen a gradual and slow transition path. Recent mortality trends in Belarus are explored in detail here, and are contrasted with those observed in Lithuania and Russia. Including a cause-of-death analysis sheds more light on the plausible determinants of the variations in mortality levels between the countries.     

SPECTACLES OF ETHNICITY: FESTIVALS AND THE COMMODIFICATION OF ETHNIC CULTURE AMONG LOUISIANA CAJUNS

Drawing on the example of the Louisiana Cajuns, an ethnic group that has been enjoying a wave of popular revival in recent years, this study suggests that changes in the perception of an ethnic identity are related to socioeconomic transformation. We identify the festival as a key aspect of the Cajun revival since the 1960s. An examination of the history, activities, and contemporary spatiotemporal organization of festivals reveals similarities to other aspects of a society of mass consumption. Niche marketing , the structuring of recreation around the modern work week, and the establishment of personal identity through the purchase of symbolically rich commodities are all embodied in present - day Cajun festivals. At the same time, the consumption of ethnic commodities is linked by the consumers with a sense of tradition and descent from a mythic past. The festivals of southwestern Louisiana are, in this sense, invented traditions and, paradoxically, a measure of the assimilation of this particular ethnic group into American culture.     

Functional data analysis: estimation of the relative error in functional regression under random left-truncation model

In this paper, we investigate the relationship between a functional random covariable and a scalar response which is subject to left-truncation by another random variable. Precisely, we use the mean squared relative error as a loss function to construct a nonparametric estimator of the regression operator of these functional truncated data. Under some standard assumptions in functional data analysis, we establish the almost sure consistency, with rates, of the constructed estimator as well as its asymptotic normality. Then, a simulation study, on finite-sized samples, was carried out in order to show the efficiency of our estimation procedure and to highlight its superiority over the classical kernel estimation, for different levels of simulated truncated data.     

Differences in health determinants between international and domestic students at a German university

The authors used a standardized questionnaire to survey 201 international and 193 German students at the University of Bielefeld, Germany, to determine differences in health practices between the 2 groups and to identify targets for health-promoting interventions. Multivariate logistic regression models revealed that long-term female international students (those whose duration of residency in Germany was more than 2 years) had lower levels of physical activity and alcohol consumption than their German counterparts and higher rates of smoking independently associated with international citizenship. Short-term international female students were less likely than German students to receive social support. Among men, long-term international student status was associated with daily smoking and inconsistent seat belt use, whereas short-term student status was associated with a lower rate of seat belt use, a higher level of perceived stress, and a healthier diet, compared with domestic students. Findings from the study could give rise to health-promotion activities for international students at German universities; additional studies at other European universities are necessary before making further recommendations.
