Sex Differences in Mortality at the Local Level: An Analysis of Belgian Municipalities

Explanations for the consistentfemale mortality advantage have ranged from thebiological, through the behavioural to thesocial, but we are still far from asatisfactory explanation. The current mortalityadvantage, which women enjoy in almost allsocieties and age groups, is not a historicaluniversal. Indeed, it may even be a uniquedevelopment of the 20th century. Even ifthis is the case, however, this does not makeit a necessary corollary of low mortality.Human mortality reflects the pattern of socialrelationships, standards of living, livingarrangements, and patterns of power andinequality in the society, and althoughmortality levels are similar for men and forwomen, they nonetheless display importantdifferences. These differences, in their turn,reflect the pattern of relationships betweenmen and women in the society. The presentanalysis looks at mortality levels anddifferences between men and women in Belgium.We focus on aggregate effects at themunicipality level (the smallest level oflocal government), and show that mortality isnegatively associated with high standards ofliving; familial solidarity; immigrantconcentration and a stable, locally born,population. It is positively associated with ahigh tendency to cohabitation. Male mortalityis more sensitive to social conditions than isfemale mortality so that as conditions improvethe female mortality advantage declines. Wealso show that net of these conditions thereremains a mortality disadvantage inWallonia, and this can only partly be explainedin terms of social differences between the twomajor regions of the country.     

Comparison of Temperament and Character Between Early- and Late-Onset Korean Male Pathological Gamblers

Purposes  

We investigated differences in temperament and character between early and late onset Korean pathological gamblers to identify whether the age of onset of pathological gambling (PG) could discriminate PG subtypes, like in alcoholism.     

Poker Mania and Problem Gambling: A Study of Distorted Cognitions,Motivation and Alexithymia

This study examines the relationships between distorted cognitions, motivation, and alexithymia on problem gambling in poker players (n = 96). Respondents completed questionnaires containing the Canadian Problem Gambling Index, Gambling Motivation Scale, Gambler’s Beliefs Questionnaire, and Toronto Alexithymia Scale-20. The results suggest that problem gambling is significantly related to distorted cognitions, non-self-determined motivation, and difficulty identifying feelings. Implications are drawn for the development of more relevant intervention, prevention, and treatment strategies.     

A New Approach to Estimating Life Tables with Covariates and Constructing Interval Estimates of Life Table Quantities

Extant approaches to constructing life tables generally rely on the use of population data, and differences between groups defined by discrete characteristics are examined by disaggregating the data before estimation. When sample data are used, few researchers have attempted to include covariates directly in the process of estimation, and fewer still have attempted to construct interval estimates for state expectancies when covariates are used. In this paper, we present a Bayesian approach that is useful for producing interval estimates for single‐decrement, multiple‐decrement, and multistate life tables. The method involves (1) estimating a hazard or survival model using Bayesian Markov chain Monte Carlo (MCMC) methods to produce a sample from the posterior distribution for the parameters of the model; (2) generating distributions of transition probabilities for selected values of covariates using the sample of model parameters; (3) using these distributions of transition probabilities as inputs for life table construction; and (4) summarizing the distribution of life table quantities. We illustrate the method on data simulated from the Berkeley Mortality Database, data from the National Health and Nutrition Examination Survey (and follow‐ups), and data from the National Long Term Care Survey, and we show how the results can be used for hypothesis testing.     

The Boom‐Bust‐Recovery Cycle: Dynamics of Change in Community Satisfaction and Social Integration in Delta,Utah*

Abstract To better understand the long‐term effects of rapid boom growth, we reexamine four subjective indicators of community satisfaction and social integration in Delta, Utah, that were originally analyzed by Brown, Geertsen, and Krannich in 1989. With 24 years of longitudinal data, we find that within approximately a decade of the boom period three of the four indicators returned to or exceeded pre‐boom levels. We argue that we need to modify our theories and vocabulary regarding boomtowns to account for a “boom‐bust‐recovery cycle” that better takes into consideration the dynamic nature of communities and their residents and how they subjectively adjust to shifts in objective conditions.     

Moving Forward with Research on Adolescence: Some Reflections on the State of JRA and the State of the Field

Over the past 5 years the scientific study of adolescence has continued to grow in volume and sophistication. Drawing on recent articles published in the Journal of Research on Adolescence, I take this opportunity to comment on some common understandings about the nature of adolescent development and behavior, recurrent tensions in the research, and promising directions or special challenges for future investigations. The journal also has changed in significant ways over this period, thanks to the outstanding contributions of scholars and journal/publisher support staff. This editorial pays homage to their efforts.     

Bridging the Ethnic Divide: Student and School Characteristics in African American,Asian‐Descent,Latino, and White Adolescents' Cross‐Ethnic Friend Nominations

Based on the revised social contact theory, correlates of cross‐ethnic friend nomination among 580 African American, 948 Asian‐descent, 860 Latino, and 3986 White adolescents were examined. Socioeconomic and academic disparities between ethnic groups differentiated cross‐ethnic friend nomination between schools for all groups but African Americans. For all groups, cross‐ethnic friend nomination was less likely among students who preferred same‐ethnic friends. Academic orientations were associated with cross‐ethnic friend nomination positively for African American and Latino, but negatively for White participants. Longer family residence in the U.S. and English language facility was associated positively with cross‐ethnic friend nomination for Asian‐descent and Latino participants. Results point to the need to differentiate hypotheses by ethnic group, and to consider individual‐in‐context models in cross‐ethnic friend nomination.     

Period analysis of variable stars by robust smoothing

Summary.  The objective is to estimate the period and the light curve (or periodic function) of a variable star. Previously, several methods have been proposed to estimate the period of a variable star, but they are inaccurate especially when a data set contains outliers. We use a smoothing spline regression to estimate the light curve given a period and then find the period which minimizes the generalized cross-validation (GCV). The GCV method works well, matching an intensive visual examination of a few hundred stars, but the GCV score is still sensitive to outliers. Handling outliers in an automatic way is important when this method is applied in a 'data mining' context to a vary large star survey. Therefore, we suggest a robust method which minimizes a robust cross-validation criterion induced by a robust smoothing spline regression. Once the period has been determined, a nonparametric method is used to estimate the light curve. A real example and a simulation study suggest that the robust cross-validation and GCV methods are superior to existing methods.
