Abstract Nonmetropolitan-metropolitan differences in the United States are large and growing, but we know relatively little about how they interact with gender differences. Using data from the CPS, the Census PUMS, and the GSS, we find nonmetropolitan and metropolitan areas are quite similar in the gender gap in earnings and in rates of married women's labor force participation. Occupational sex segregation is higher and some gender attitudes are a few percentage points less egalitarian in nonmetropolitan areas. Each of these dimensions of gender stratification has been declining over the last two decades and the declines are roughly similar in nonmetropolitan and metropolitan areas. Variations in gender stratification have been greater over time than across place. Thus, while both place and gender are important dimensions of stratification, there appears to have been little interaction between the two.  相似文献

The Production and Operations Management Society is the largest professional society dedicated to creating and disseminating knowledge in product and process design, operations, and supply chains for the management of manufacturing and services. Its research journal, Production and Operations Management (POM), covers all topics in the discipline and all research paradigms to serve the entire community. Since its inception in 1992, POM has become recognized as a top tier outlet for operations management research. We identify research institutions in the operations management community that have played major roles in developing the journal based on the research of their faculty members and doctoral graduates. Our findings show that the constituency of the journal reflects the constituency of the society.  相似文献

Examining children's perceptions of their social acceptance in conjunction with others’ ratings of their peer social standing can enhance our understanding of the heterogeneity in children exhibiting disruptive behavior problems. Using a sample of 213 youth rated in the top 31 percent of their class on aggressive–disruptive behaviors, the current study examined the interaction between children's perceptions of their social acceptance and their peer‐rated social standing in predicting emotional and behavioral problems. Overall, lower peer‐rated social standing was associated with higher levels of antisocial behavior, academic problems, and hyperactivity/inattention. On the other hand, higher self‐perceived social acceptance was associated with increased levels of peer‐rated fighting at school. For children who were rated as having high social standing among their peers, poorer self‐perceived social acceptance was associated with increased oppositional behaviors and conduct problems at home. In addition, children who reported lower self‐perceived social acceptance exhibited increased levels of depressive symptoms, even when they were relatively well liked by their peers. The potential implications for working with subgroups of children with aggressive–disruptive behaviors are discussed.  相似文献

The nearest neighbour analysis method has been developed to determine whether a disease case may be regarded as being unusually close to other neighbouring cases of the same disease. Using this method, each disease case is classified as spatially 'clustered' or 'non-clustered'. The method is also used to provide a test for global clustering. 'Clusters' are constructed by amalgamating geographically neighbouring clustered cases into one contiguous 'cluster area'. This paper describes a method for studying differences between clustered and non-clustered cases, in terms of case 'attributes'. These attributes may be person related, such as age and sex, or area based, such as geographical isolation. The area-based variables are subject to geographical correlation. The comparison of clustered and non-clustered cases may reveal similarities or differences, which may, in turn, give clues to disease aetiology. A method for studying 'linkage' or similarities in attributes between cases that occur in the same clusters is also described. The methods are illustrated by application to incidence data for leukaemias and lymphomas.  相似文献

A group of 22 parents of adolescent sexual offenders (PASO) was compared with a group of 19 normal controls (NC) and 10 clinical controls (CC) on demographic, developmental, personal adjustment and family environment variables. The assessment protocol included the General Health Questionnaire‐12, the Culture‐Free Self‐Esteem Inventory, the Child Behaviour Checklist, the Family Assessment Device, the Parent Satisfaction Scale and the Multidimensional Scale of Perceived Social Support. Compared with clinical and normal controls, more parents in the PASO group reported that they had been arrested or charged for a criminal offence; had personally experienced child abuse; and more of their adolescents had experienced child abuse, with emotional abuse being the most common form of abuse for both parents and adolescents. Compared with clinical and normal controls, more adolescents of parents in the PASO group had witnessed parental drug or alcohol abuse and had been placed in care outside their home. While parents in the PASO group did not differ from clinical or normal controls in terms of personal adjustment, their adolescents had significantly more internalizing behaviour problems than normal controls, whereas adolescents of parents in the clinical control group had significantly more externalizing behaviour problems than normal controls. Compared with normal controls, parents in both the PASO and clinical control groups reported more difficulties with general family functioning, roles, affective responsiveness, affective involvement and behaviour control and lower levels of parental satisfaction. However, the groups did not differ significantly in their levels of perceived social support. Copyright © 2003 John Wiley & Sons, Ltd.  相似文献

Hierarchical Financial Needs Reflected by Household Financial Asset Shares   总被引:2,自引:0,他引:2  
This study explores the relationship between family financial needs and household financial asset shares. A conceptual framework based on the needs hierarchy theory, new consumer demand theory, and prospect theory guides the investigation. Results from the bivariate and tobit analyses suggest that family financial needs are hierarchical that are reflected by patterns of financial asset shares. Specifically, checking and savings accounts represent the lowest-level survival needs, and bonds and stocks represent the highest-level growth needs. The rest of the financial assets examined, except for trusts, represent the middle-level security needs.  相似文献

One half of D. Super's (D. Super, M. Savickas, & C. Super, 1996) theoretical propositions that relate to abilities have been operationalized into a psychometric instrument, the Ability Explorer (T. Harrington & J. Harrington, 1996). Interpretations illustrate how D. Super's career development theoretical concepts can be implemented in career counseling.  相似文献

The authors propose a method for comparing two samples of curves. The notion of similarity between two curves is the basis of three statistics they suggest for testing the null hypothesis of no difference between the two groups. They exploit standard tools from functional data analysis to preprocess the observed curves and use the permutation distribution under the null hypothesis to obtain p‐values for their tests. They explore the operating characteristics of these tests through simulations and as an application, compare the ganglioside distribution in brain tissue between old and young rats.  相似文献

We analyze a model of conflict with endogenous choice of effort, where subsets of the contenders may force the resolution to be sequential: First the alliance fights it out with the rest and – in case they win – later they fight it out among themselves. For three-player games, we find that it will not be in the interest of any two of them to form an alliance. We obtain this result under two different scenarios: equidistant preferences with varying relative strengths, and varying vicinity of preferences with equal distribution of power. We conclude that the commonly made assumption of super-additive coalitional worth is suspect.  相似文献
