This study examined the relationship between attachment style, differentiation of self, and body dissatisfaction across culture and gender. The sample consisted of 115 Caucasians (85 females, 29 males) with a mean age of 22.2 years (SD = 5.81) and 119 Chinese individuals (93 females, 26 males) with a mean age of 22.8 years (SD = 2.35). Participants completed online self-report measures of body satisfaction, attachment style, and differentiation of self. Results indicated that high attachment anxiety and less differentiation of self were associated with lower body satisfaction for women but not for men of either cultural group. There were no significant cultural or gender differences in terms of overall body satisfaction; however, there were differences with regard to preoccupation with weight and self-perceived weight. It was concluded that culture had little impact on body dissatisfaction in the present sample but that the factors that shape body dissatisfaction differed by gender.  相似文献

Abstract Using the National Survey of Family Growth, we document nonmetropolitan and metropolitan single mothers' economic livelihood strategies. We have three objectives: (1) examine differences in employment, cohabitation, co‐residence with other adults, and welfare receipt; (2) evaluate how these livelihood strategies are associated with economic well‐being; and (3) identify key metro‐nonmetro differences in the effectiveness of these livelihood strategies in improving the economic well‐being of single mothers. We find surprisingly similar livelihood strategies in nonmetropolitan and metropolitan areas. Employment, cohabitation, and co‐residence are strongly associated with economic well‐being. However, nonmetro single mothers are less likely than metropolitan mothers to benefit economically from full‐time employment. Given our results, “work‐first” policies are likely to be less efficacious in nonmetropolitan areas. Indeed, nonmetropolitan single mothers are often “triply disadvantaged” compared to their metro counterparts; they experience higher rates of poverty, higher barriers to welfare receipt, and lower economic returns from other livelihood strategies.  相似文献

Raptors are the most prevalent group of urban apex predators, and the majority of raptor genera in North America have been recorded using urban areas. Prior research assessments along urban-wildland gradients show that urban habitat preference varies by raptor species and that raptor nesting preferences within urban settings may vary. Attempts to understand the intra- and inter-specific nesting patterns along an urban gradient would advance extant knowledge. Here we present the locations of individual nest sites of nine raptor species along an urban gradient in Reno-Sparks, NV. We developed an urban density model based on the number of residents, number of employees, and building footprints and number of floors for built structures within each land parcel at four spatial scales, representing nest site, macrohabitat, average nearest-nest, and landscape scales. Cooper’s Hawks (Accipiter cooperii), Sharp-shinned Hawks (Accipiter striatus), and Red-tailed Hawks (Buteo jamaicensis) nested across the widest range of the urban spectrum and closest to the urban core, whereas Golden Eagles (Aquila chrysaetos) and Swainson’s Hawks (Buteo swainsonii) nested on the urban fringe. Urban density for all nest locations was lowest at the nest-site scale, and the highest at the average nearest-nest and landscape scales. Raptors tended to occupy a wide range of the building-area density spectrum but not the building-height or employee density spectrums indicative of the attractiveness of suburban habitat.

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.  相似文献

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.  相似文献

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.  相似文献
