Variations in the pace of old-age mortality decline in seven European countries, 1950–1999: the role of smoking and other factors earlier in life

We examine the variations in the pace of old-age (80+) mortality decline in seven European countries, from 1950 to 1999. Marked variations were found between countries, periods and sexes. While mortality declines were strong in France and England and Wales, modest or no mortality declines were seen in the 1950s and 1960s in the Nordic countries, and since the 1980s in Denmark, the Netherlands and Norway (men only). For non-smoking-related mortality, a high and consistent pace of mortality decline was observed. Mortality decline stagnated among men born between 1890 and 1899, but persisted among women born between 1847 and 1937. The pace of old-age mortality decline correlated with the pace of mortality decline at ages 60–69 among the same cohorts, but only among men and not for non-smoking-related mortality. Smoking, thus, seems more important than other factors originating earlier in life. Our results furthermore indicate substantial future declines in old-age mortality.     

Creative crisis: New patterns of growth and employment

Unemployment as a factor of economic and social life is likely to be with us for some time, and may well double within the next few years. The author makes a critical review of the traditional remedies and suggests ways in which the situation might be alleviated or dealt with in a positive fashion.Resignation in the face of the crisis will only lead to new crises. Proposals for new patterns of growth are suggested and a new attitude to planning within the situation.     

Review of Chinese sex attitudes and applicability of sex therapy for chinese couples with sexual dysfunction

Although sex therapy techniques have widely been used to help Western couples with sexual dysfunction, there has been little research on the applicability of these techniques among Chinese couples. This article discusses the Chinese views and concepts of sex and sexual dysfunction in the past and present, culturally bound sexual problems, and gender role stereotypes. We suggest that with careful integration of the therapeutic techniques with Chinese sex concepts, sex therapy can be applied to Chinese Couples experiencing problems in sexual functioning.     

Leaving the ‘perfect DREAMer’ behind? Narratives and mobilization in immigration reform

This paper focuses on the consequences of the narrative used to support immigration reform by some immigrant activists, and especially how this narrative may negatively impact potential allies. Policies and policy proposals such as the Development, Relief and Education for Alien Minors (DREAM) Act, and Deferred Action for Childhood Arrivals have been consistently championed using a specific narrative of undocumented youths which presents them as well-assimilated, driven, and US-educated. The paper is drawn from 60 in-depth interviews conducted with undocumented youths in 2013 in New York City and northern New Jersey. The paper builds on the literature relative to narratives in social movements, framing and policy-making. Findings indicate that recent campaigns continue to make extensive use of this narrative, even though it creates a divide within the undocumented community. This unintended consequence has recently led some activists to step away from the ‘perfect DREAMer’.     

A Shorter and Multidimensional Version of the Gambling Attitudes and Beliefs Survey (GABS-23)

The Gambling Attitudes and Beliefs Survey (GABS) is a questionnaire which explores gambling-related dysfunctional beliefs in an unidimensional way. The present research aims to investigate the dimensionality of the scale. 343 undergraduate student gamblers and 75 pathological gamblers seeking treatment completed the GABS and the south oaks gambling screen. Exploratory and confirmatory factor analyses revealed that the original one-factor structure of the GABS did not fit the data effectively. We then proposed a shorter version of the GABS (GABS-23) with a new five-factor structure, which fitted with the data more efficiently. The comparisons between students (problem vs. non-problem gamblers) and pathological gamblers seeking treatment indicated that the GABS-23 can discriminate between problem and non-problem gamblers as efficiently as the original GABS. To ensure the validity and the stability of the new structure of the GABS-23, analyses were replicated in an independent sample that consisted of 628 gamblers (256 non problem gamblers, 169 problem gamblers who are not treatment-seeking and 203 problem gamblers seeking treatment). Analyses showed satisfactory results, and the multidimensional structure of the GABS-23 was then confirmed. The GABS-23 seems to be a valid and useful assessment tool for screening gambling-related beliefs, emotions and attitudes among problem and non-problem gamblers. Moreover, it presents the advantage of being shorter than the original GABS, and of screening irrational beliefs and attitudes about gambling in a multidimensional way. The five-factor model of the GABS-23 is discussed based on the theory of locus of control.     

Clinical Profiles as a Function of Level and Type of Impulsivity in a Sample Group of At-risk and Pathological Gamblers Seeking Treatment

Level and type of impulsivity are essential variables to be taken into consideration during the initial evaluation of a pathological gambler. The aim of this study was to measure the score for 4 impulsivity-related traits (Urgency, (lack of) Premeditation, (lack of) Perseverance and Sensation seeking) in a sample group of at-risk and pathological gamblers, and to highlight any links with certain elements of clinical data. The UPPS Impulsive Behaviour Scale was administered to 84 problem gamblers seeking treatment. The severity of gambling disorders was evaluated using the diagnostic criteria of the DSM-IV. Psychiatric and addictive comorbidities were also explored. The results indicated that the score for the Urgency facet had a positive correlation with the severity of gambling disorders. It appeared that participants displayed different clinical profiles according to the level and type of impulsivity. Several of the UPPS scales were identified as risk factors for mood disorders, risk of suicide, alcohol use disorders, and Attention Deficit/Hyperactivity Disorder (ADHD). The results confirm both the complexity of the multi-dimensional concept of impulsivity and the reason why the UPPS is of interest for a more in-depth study of the subject.     

An Assessment and Extension of the Mechanism-Based Approach to the Identification of Age-Period-Cohort Models

Many methods have been proposed to solve the age-period-cohort (APC) linear identification problem, but most are not theoretically informed and may lead to biased estimators of APC effects. One exception is the mechanism-based approach recently proposed and based on Pearl’s front-door criterion; this approach ensures consistent APC effect estimators in the presence of a complete set of intermediate variables between one of age, period, cohort, and the outcome of interest, as long as the assumed parametric models for all the relevant causal pathways are correct. Through a simulation study mimicking APC data on cardiovascular mortality, we demonstrate possible pitfalls that users of the mechanism-based approach may encounter under realistic conditions: namely, when (1) the set of available intermediate variables is incomplete, (2) intermediate variables are affected by two or more of the APC variables (while this feature is not acknowledged in the analysis), and (3) unaccounted confounding is present between intermediate variables and the outcome. Furthermore, we show how the mechanism-based approach can be extended beyond the originally proposed linear and probit regression models to incorporate all generalized linear models, as well as nonlinearities in the predictors, using Monte Carlo simulation. Based on the observed biases resulting from departures from underlying assumptions, we formulate guidelines for the application of the mechanism-based approach (extended or not).     

Mother–Infant Interaction and Child Brain Morphology: A Multidimensional Approach to Maternal Sensitivity

Emerging research suggests that normative variation in parenting quality relates to children's brain development. However, although the young brain is presumed to be especially sensitive to environmental influence, to our knowledge only two studies have examined parenting quality with infants as it relates to indicators of brain development, and both were cross‐sectional. This longitudinal study investigated whether different components of maternal sensitivity in infancy predicted the volume of two brain structures presumed to be particularly sensitive to early experience, namely the amygdala and the hippocampus. Three dimensions of sensitivity (Cooperation/Attunement, Positivity, Accessibility/Availability) were observed in 33 mother–infant dyads at 1 year of age and children underwent structural magnetic resonance imaging at age 10. Higher maternal Accessibility/Availability during mother–infant interactions was found to be predictive of smaller right amygdala volume, while greater maternal positivity was predictive of smaller bilateral hippocampal volumes. These longitudinal findings extend those of previous cross‐sectional studies and suggest that a multidimensional approach to maternal behavior could be a fruitful way to further advance research in this area, given that different facets of parenting might be differentially predictive of distinct aspects of neurodevelopment.     

An exponential (matching based) neighborhood for the vehicle routing problem

We introduce an exponential neighborhood for the Vehicle Routing Problem (vrp) with unit customers’ demands, and we show that it can be explored efficiently in polynomial time by reducing its exploration to a particular case of the Restricted Complete Matching (rcm) problem that we prove to be polynomial time solvable using flow techniques. Furthermore, we show that in the general case with non-unit customers’ demands the exploration of the neighborhood becomes an -hard problem.
