We use unique data in which both partners report about household finances to demonstrate that there is often disagreement about whether the household has experienced financial difficulty in the past year. Four alternative explanations for this disagreement are tested using the data. The results indicate that disagreement may be related to the severity of the underlying material hardship rather than to gender differences or individual (as opposed to household) views of financial difficulty. We find limited evidence that for some couples information asymmetries contribute to explaining disagreement about financial difficulty. This implies that standard surveys which collect information about the household’s financial position from a representative individual may fail to completely characterize the nature of material hardship.   相似文献

Previous research has shown that indirect measures of occupational status such as the Duncan Socioeconomic Index (SEI) are more valid than direct measures of occupational prestige, such as those developed by the National Opinion Research Center and by Treiman, for analyses of social mobility. The Professional, Technical, and Kindred (PTK) occupations available for the SEI are a biased sample of all PTK occupations. Do findings on the validity of the SEI pertaining to the general population hold for special populations, such as college graduates? Confirmatory factor analysis comparing the validities of four measures of occupational SES—the SEI, a 1960 counterpart of the SEI developed by Siegel and based on all Census occupations, the NORC prestige scale, and the Treiman international prestige scale—showed that the indirect measure developed by Siegel was clearly more valid than the other three measures. Since these findings indicate that the predictors in a regression equation are more valid than the criterion, there is some question as to what the criterion should really be.  相似文献

PurposeEvidence-based program registers (EBPRs) are important tools for facilitating the use of evidence-based practices or programs (EBPs) by state statutory agencies responsible for behavioral healthcare, broadly defined as substance misuse, mental health, HIV/AIDS prevention, child welfare, and offender rehabilitation. There are currently no data on the purposes for which such state agencies reference EBPRs on their official websites.MethodA webscraping method was used to identify and classify relevant “hits”, defined as a state behavioral health webpage with single or multiple references to a study EBPR. A total of 778 hits (unique combinations of webpage and register) were coded. Up to three codes were applied to each hit for the “reasons for the EBPR reference” (EBPR use) dimension, one code was applied to each hit for the “purpose of the EBPR reference” and “intended audience of the webpage containing the hit” dimensions, and up to two codes were applied to each hit for the "funding mentions” dimension.ResultsThree EBPRs out of 28 accounted for 73.6% of the hits. The most frequent reason for referencing EBPRs were as a resource for selecting EBPs or validating existing programs and practices. The references tended to appear in reports from the state, in training materials, or guidelines. The references tended to address broad groups of behavioral healthcare professionals. EBPRs were frequently referenced in the context of federal block grants or other federal funding.ConclusionsIncreasing state agencies’ awareness and use of the entire range of existing EBPRs may improve implementation of EBPs nationally.  相似文献

青少年网络成瘾影响因素分析   总被引:2,自引:1,他引:1  
成瘾是现代社会生活中一个重要的社会问题。随着互联网的迅速普及和广泛使用,网络成瘾作为一种新的社会成瘾形式,日益引起人们的关注。尝试从结构一行为视角,建构一个以青少年个体特征、现实社会差异、网络介入程度为解释变量,以网络成瘾规模和成瘾倾向为被解释变量的分析架构,对青少年网络成瘾的影响因素进行分析和梳理。在此基础上,提出青少年网络成瘾社会控制的基本对策。  相似文献

Intergenerational relationships are a topic of general concern to social scientists because of the importance of the family for individual's well-being, especially in times of crisis. Hence, a considerable amount of research on relationships between parents and their adult children has been published in a broad array of social science journals. Most of this research examines intergenerational relationships from the perspective of only one generation and implicitly assumes that we would get the same results if we were to examine the relationships from the point of view of other family members. In societies where there are strong norms regarding kin contact, this assumption is likely to be invalid. This research examines reported levels of face-to-face contact among kin in the USA and Japan, and tests whether these reports are systematically different for respondents in some kinship positions than in others. The results show that norms favoring patrilineal contact in Japan can produce reporting bias. In Japan, married daughters tend to underreport levels of contact with their parents. In the USA, children-in-law report lower levels of visiting.  相似文献

During the past decade, some efforts have been put forth by researchers towards integrating Total Quality Management (TQM) and Business Process Reengineering (BPR) principles. The results of the majority of research work carried out in this direction have been scattered and have not been applied in practice. In this context this paper is being brought out with the aim of reporting the literature survey conducted with the objective of evolving future direction of research imperatives for integrating TQM and BPR principles. The literature survey was carried out by using CD-ROM journal called Anbar Electronic Intelligence (AEI) (published by MCB University Press, UK) and by visiting the site maintained by Emerald Library, UK. On systematic analyses, it was found that the integration of BPR with the quality strategies identified in a theoretical Strategic Quality Management model would make a meaningful start in this direction.  相似文献

Measurement error is often a severe problem in longitudinal data such as labor-market flows. Two correction methods have been used for labor-market flows, but the methods tend to adjust the data in opposite directions. One method shows a rigid labor market with long unemployment spells, whereas the other shows the opposite. Because the methods appear theoretically similar, one might interpret the differing results as an indictment of both procedures. This article documents and explains the differences between the two methods. More important, it argues that the differences result from the reliance of one method on assumptions that are theoretically implausible and rejected by the data.  相似文献

Beginning with the 1990 Census and the January 1992 Current Population Survey (CPS), the Bureau of the Census changed the emphasis of its educational-attainment question from years of education to degree receipt. Using a matched sample from the 1991 and 1992 March CPS, this article addresses how to reconcile the old and new questions. The effects of those methods on the estimated return(s) to education are then examined. Both the estimated linear return and the estimated college–high-school wage differential are slightly larger using information from the new question.  相似文献
