We examine the link between the postponement of parenthood and fertility outcomes among highly educated women in the USA born in 1920–1986, using data from the CPS June Supplement 1979–2016. We argue that the postponement–low fertility nexus noted in demographic and biomedical research is especially relevant for women who pursue postgraduate education because of the potential overlap of education completion, early career stages, and family formation. The results show that women with postgraduate education differ from women with college education in terms of the timing of the first birth, childlessness, and completed fertility. While the postponement trend, which began with the cohorts born in the 1940s, has continued among highly educated women in the USA, its associations with childlessness and completed parity have changed considerably over subsequent cohorts. We delineate five distinct postponement phases over the 80-year observation window, consistent with variation over time in the prevalence of strategies for combining tertiary education and employment with family formation. 相似文献

There have been claims that some child molesters engage in a “seduction stage” prior to committing abuse. These behaviors, commonly known as “grooming,” are understood as methods child molesters use to gain access to and prepare future victims to be compliant with abuse. However, there is a lack of consensus regarding exactly what this process entails and how it is clearly distinguished from normal adult–child interactions. It is important to devise an accurate definition of grooming for scientific, clinical, and forensic purposes. We critically evaluate the various definitions and reveal problematic heterogeneity. Furthermore, there are no methods of known psychometrics to validly assess grooming. We review the empirical literature regarding the occurrence of grooming and propose future directions for research. 相似文献

During the 1990s, the number of regional consultative processes focusing on migration increased significantly. These non‐binding fora brought together representatives of States, civil society and international organizations at the regional level to discuss migration‐related issues in a cooperative manner. Regional consultative processes, which are increasingly supported by governments, are partly a response to the growing complexity and diversity of international migration. Their emergence attests the importance that governments attach to a regional approach to migration management. Regional processes act informally, focusing on cooperative dialogue with an emphasis on information exchange and technical cooperation. The information exchange and confidence‐building that occurs in regional processes is quite important in terms of developing links between States and influencing the likelihood of future bilateral and multilateral agreements. This article focuses upon the development of regional processes, using examples as illustrations. It suggests that the development of regional processes can be understood in terms of a four‐stage model: first, the decision to address issues of concern in a cooperative regional forum; second, to agree upon a “common language”; third, to agree upon a list of goals and, fourth, a shift toward a more operational process. 相似文献

This article presents a new approach of estimating the parameters describing the mean structure in the Growth Curve model when the number of variables compared with the number of observations is large. An unbiased, consistent, and asymptotic normal estimator is derived as well as its. 相似文献

Since the terrorist attacks of September 11, 2001, and the subsequent establishment of the U.S. Department of Homeland Security (DHS), considerable efforts have been made to estimate the risks of terrorism and the cost effectiveness of security policies to reduce these risks. DHS, industry, and the academic risk analysis communities have all invested heavily in the development of tools and approaches that can assist decisionmakers in effectively allocating limited resources across the vast array of potential investments that could mitigate risks from terrorism and other threats to the homeland. Decisionmakers demand models, analyses, and decision support that are useful for this task and based on the state of the art. Since terrorism risk analysis is new, no single method is likely to meet this challenge. In this article we explore a number of existing and potential approaches for terrorism risk analysis, focusing particularly on recent discussions regarding the applicability of probabilistic and decision analytic approaches to bioterrorism risks and the Bioterrorism Risk Assessment methodology used by the DHS and criticized by the National Academies and others. 相似文献

Much of the work–family literature focuses on job or family characteristics that impact on work–life interaction. A small body of research takes a wider perspective, highlighting the importance of community characteristics. This study builds on, and extends, this research by examining the way work and community characteristics may interact in their influence on work–family interaction. Building on Voydanoff's work, this study examined whether community demands amplified the impact of work demands on work–family conflict, and whether community resources increased the impact of work resources on work–family facilitation. Data were analyzed from the Household, Income and Labour Dynamics in Australia survey, distinguishing between residents of higher or lower socioeconomic status (SES) communities. Work demands (work intensity, hours) demonstrated the strongest relationship with work–family interaction. Autonomy and work hours emerged as particularly important predictors of work–family interaction for those living in lower SES areas. Whereas social support (a community resource) was a particularly strong predictor of work–family interaction for those living in higher SES areas. There was also evidence that community demands (lack of safety) are independently associated with work–family interaction and also amplify the effect of job demands (work intensity) on work–family conflict for residents of lower SES areas. 相似文献
