Objective. Beginning with the 1993 election, Canada's Progressive Conservative Party was replaced as the dominant force on the political right by the more ideological Reform Party/Canadian Alliance. This article examines what specific issues most centrally motivated this seismic shift among conservative Canadians. Method. Using data from the 1993, 1997, and 2000 Canadian Election Studies, we employ bivariate analyses and multinomial logit voting models to determine whether constitutional, economic, nativist, or moral issues most clearly differentiate PC supporters from R/A voters. Results. Regional concerns are important and other issues have sporadic impacts, but moral traditionalism is the most consistent and powerful factor distinguishing supporters of the new party from supporters of the old one. Conclusions. Although existing studies have focused primarily on other sources of R/A support, moral traditionalism is clearly a key factor in explaining the party's ascendancy. This phenomenon, we contend, is part of a larger trend toward postmaterial politics in Western democracies. 相似文献

Child Anger Regulation, Parental Responses to Children's Anger Displays, and Early Child Antisocial Behavior 总被引:4,自引:0,他引:4
The display and regulation of child anger in family interaction was coded in a sample of 240 boys and girls at child age 6, and coded using the Specific Affect Coding System. Child antisocial behavior was longitudinally assessed, beginning in kindergarten. Pooled‐ and family‐level analyses were used to assess hazard rates for child anger. Parents’ ability to modulate their own emotions and negative behavior, and children's ability to down‐regulate anger were associated with increased latency for child anger. Hazard for child anger increased as parents’ insensitive and negative responses toward the child cumulated during family interaction. Macro‐level, non‐hazard analyses indicated that chronic levels of child antisocial behavior were associated with the frequency of parental negative behavior, but not with the frequency of child anger. Micro‐level hazard analyses indicated that children's ability to regulate anger was related to chronic levels of child covert but not overt antisocial behavior. 相似文献

The family educator works with the client's family members to help in their understanding of their ill relative and to assist with managing the stress of the caregiver role. Families come to understand that they can join forces with the clinical team in helping their relative engage in a trial of treatment. Each treatment recommendation is explained to the family and decisions are arrived at by consensus through partnership meetings. Role modeling effective interaction approaches and providing assistance in generating alternative solutions to problematic situations are important functions of the family educator. 相似文献

Ethylene oxide is a gas produced in large quantities in the United States that is used primarily as a chemical intermediate in the production of ethylene glycol, propylene glycol, non-ionic surfactants, ethanolamines, glycol ethers, and other chemicals. It has been well established that ethylene oxide can induce cancer, genetic, reproductive and developmental, and acute health effects in animals. The U.S. Environmental Protection Agency is currently developing both a cancer potency factor and a reference concentration (RfC) for ethylene oxide. This study used the rich database on the reproductive and developmental effects of ethylene oxide to develop a probabilistic characterization of possible regulatory thresholds for ethylene oxide. This analysis was based on the standard regulatory approach for noncancer risk assessment, but involved several innovative elements, such as: (1) the use of advanced statistical methods to account for correlations in developmental outcomes among littermates and allow for simultaneous control of covariates (such as litter size); (2) the application of a probabilistic approach for characterizing the uncertainty in extrapolating the animal results to humans; and (3) the use of a quantitative approach to account for the variation in heterogeneity among the human population. This article presents several classes of results, including: (1) probabilistic characterizations of ED10s for two quantal reproductive outcomes-resorption and fetal death, (2) probabilistic characterizations of one developmental outcome-the dose expected to yield a 5% reduction in fetal (or pup) weight, (3) estimates of the RfCs that would result from using these values in the standard regulatory approach for noncancer risk assessment, and (4) a probabilistic characterization of the level of ethylene oxide exposure that would be expected to yield a 1/1,000 increase in the risk of reproductive or developmental outcomes in exposed human populations. 相似文献

This study assesses the effect of population change on decade changes in the educational attainments of country of origin
populations in the United States. Our data are derived from decennial censuses, NLMS, the World Bank, and INS. We find that
changes in the share of country of origin populations with one or more years of post-secondary schooling are associated with
selected components of population change during the 1980–1990 and 1990–2000 decades. The specific components include survivors
during the decade, in-migration, and emigration of the foreign-born. Likewise, intra-generational mobility is found to be
an important determinant of changes in educational attainment. The discussion addresses limitations of the data and suggests
directions for future research as well as policy implications. 相似文献

AbstractObjective: This study sought to (1) examine perceived stress and resources to cope with stress as predictors of emotional eating during the transition to college and (2) determine whether body mass index (BMI) moderated the emotional eating-stress relationship. Participants: Participants were 97 college freshmen (73% female; BMI: M = 25.3 kg/m2, SD = 5.7 kg/m2). Research was conducted in September 2012. Methods: Participants completed the Perceived Stress Scale, Emotional Eating Scale, and Eating and Appraisal Due to Emotions and Stress Questionnaire during the first month of college. Height and weight were measured objectively. Results: BMI moderated the relationship between perceived stress and emotional eating. Higher stress predicted greater emotional eating for the lower BMI groups, but not the highest group. Greater resources to cope with stress predicted lower emotional eating. Conclusions: Greater perceived stress and poorer resources to cope with stress may contribute to emotional eating during the transition to college. The relationship between perceived stress and emotional eating may vary by BMI. 相似文献

Bayesian palaeoclimate reconstruction 总被引:1,自引:0,他引:1
J. Haslett M. Whiley S. Bhattacharya M. Salter-Townshend Simon P. Wilson J. R. M. Allen B. Huntley F. J. G. Mitchell 《Journal of the Royal Statistical Society. Series A, (Statistics in Society)》2006,169(3):395-438
Summary. We consider the problem of reconstructing prehistoric climates by using fossil data that have been extracted from lake sediment cores. Such reconstructions promise to provide one of the few ways to validate modern models of climate change. A hierarchical Bayesian modelling approach is presented and its use, inversely, is demonstrated in a relatively small but statistically challenging exercise: the reconstruction of prehistoric climate at Glendalough in Ireland from fossil pollen. This computationally intensive method extends current approaches by explicitly modelling uncertainty and reconstructing entire climate histories. The statistical issues that are raised relate to the use of compositional data (pollen) with covariates (climate) which are available at many modern sites but are missing for the fossil data. The compositional data arise as mixtures and the missing covariates have a temporal structure. Novel aspects of the analysis include a spatial process model for compositional data, local modelling of lattice data, the use, as a prior, of a random walk with long-tailed increments, a two-stage implementation of the Markov chain Monte Carlo approach and a fast approximate procedure for cross-validation in inverse problems. We present some details, contrasting its reconstructions with those which have been generated by a method in use in the palaeoclimatology literature. We suggest that the method provides a basis for resolving important challenging issues in palaeoclimate research. We draw attention to several challenging statistical issues that need to be overcome. 相似文献
