Abstract Building on previous theory and research, we propose a “structural relational” view of the sex gap in small business success. Our findings, based on analyses of data from 423 small business owners in Iowa, show support for our model and suggest that links between owners, social relational processes, business structure, and small business success operate differently depending on the industry location of the business and the owner's sex. Results also indicate that the business owner's sex has direct and indirect effects on business success. This finding suggests that social relations, organizations, and institutions are all gendered in ways that influence the sex gap in sales, but that further research is needed to more fully explain sex differences in small business success. We discuss these and other findings in terms of their theoretical and practical implications, and suggest directions for future research. 相似文献

This study was designed to investigate the potential association between social anxiety and children's ability to decode nonverbal emotional cues. Participants were 62 children between 8 and 10 years of age, who completed self-report measures of social anxiety, depressive symptomatology, and nonspecific anxious symptomatology, as well as nonverbal decoding tasks assessing accuracy at identifying emotion in facial expressions and vocal tones. Data were analyzed with multiple regression analyses controlling for generalized cognitive ability, and nonspecific anxious and depressive symptomatology. Results provided partial support for the hypothesis that social anxiety would relate to nonverbal decoding accuracy. Difficulty identifying emotions conveyed in children's and adults' voices was associated with general social avoidance and distress. At higher levels of social anxiety, children more frequently mislabeled fearful voices as sad. Possible explanations for the obtained results are explored. 相似文献

A university career development course based on cognitive information‐processing theory was assessed. Students who took the course showed a significant decrease in their negative career thoughts when the Career Thoughts Inventory (J. P. Sampson, G. W. Peterson, J. G. Lenz, R. C. Reardon, & D. E. Saunders, 1996a) was used as a pretest and posttest measure. The greatest decrease in negative thinking was found in students with the highest level of negative thinking at the beginning of the course. The specific components of negative career thinking—decision‐making confusion and commitment anxiety—contributed significantly to the main effect. There were no significant interactions with ethnicity or sex. 相似文献

《红楼梦》后四十回的描写,是违背曹雪芹原意的,木石前盟作为《红楼梦》的情节主线,同样是被续作者歪曲了的首先是抽去了木石前盟的思想基础——对传统观念的叛逆,其次是修正了木石前盟的爱情条件——相互尊重和人格平等的知己之爱;其三是改变了爱情主人公矢志不渝的个性特点。从而抹杀了木石前盟所体现的超越时代的积极精神。 相似文献

This study examines how strength of ethnic identity, multiethnic identity, and other indicators of biculturalism relate to the drug use norms of urban American Indian middle school students. The article distinguishes categories of norms that may affect drug use. Regression analysis of self-reports by 434 American Indian seventh graders attending middle schools in a large southwestern U.S. city indicated that students who had a more intense sense of ethnic pride adhered more strongly to certain antidrug norms than those who did not. Whereas American Indian students with better grades in school held consistently stronger antidrug norms, there were few differences by gender, socioeconomic status, or age. These results have implications in social work practice for better understanding and strengthening the protective aspects of American Indian culture in drug prevention efforts. 相似文献

We consider a sequence of posterior distributions based on a data-dependent prior (which we shall refer to as a pseudoposterior distribution) and establish simple conditions under which the sequence is Hellinger consistent. It is shown how investigations into these pseudo posteriors assist with the understanding of some true posterior distributions, including Pólya trees, the infinite dimensional exponential family and mixture models. 相似文献

Nonparametric estimation of the mean function of a stochastic process with missing observations 总被引:1,自引:1,他引:0
In an attempt to identify similarities between methods for estimating a mean function with different types of response or
observation processes, we explore a general theoretical framework for nonparametric estimation of the mean function of a response
process subject to incomplete observations. Special cases of the response process include quantitative responses and discrete
state processes such as survival processes, counting processes and alternating binary processes. The incomplete data are assumed
to arise from a general response-independent observation process, which includes right- censoring, interval censoring, periodic
observation, and mixtures of these as special cases. We explore two criteria for defining nonparametric estimators, one based
on the sample mean of available data and the other inspired by the construction of Kaplan-Meier (or product-limit) estimator
[J. Am. Statist. Assoc. 53 (1958) 457] for right-censored survival data. We show that under regularity conditions the estimated mean functions resulting
from both criteria are consistent and converge weakly to Gaussian processes, and provide consistent estimators of their covariance
functions. We then evaluate these general criteria for specific responses and observation processes, and show how they lead
to familiar estimators for some response and observation processes and new estimators for others. We illustrate the latter
with data from an recently completed AIDS clinical trial. 相似文献
