The Gender Revolution: A Framework for Understanding Changing Family and Demographic Behavior 下载免费PDF全文
Frances Goldscheider Eva Bernhardt Trude Lappegård 《Population and development review》2015,41(2):207-239
This article argues that the trends normally linked with the second demographic transition (SDT) may be reversed as the gender revolution enters its second half by including men more centrally in the family. We develop a theoretical argument about the emerging consequences of this stage of the gender revolution and review research results that bear on it. The argument compares the determinants and consequences of recent family trends in industrialized societies provided by two narratives: the SDT and the gender revolution in the public and private spheres. Our argument examines differences in theoretical foundations and positive vs. negative implications for the future. We focus primarily on the growing evidence for turnarounds in the relationships between measures of women's human capital and union formation, fertility, and union dissolution, and consider evidence that men's home involvement increases union formation and fertility and decreases union instability. Although the family trends underlying the SDT and the gender revolution narratives are ongoing and a convincing view of the phenomenon has not yet emerged, the wide range of recent research results documenting changing, even reversing relationships suggests that the gender approach is increasingly the more fruitful one. 相似文献

In this paper, the quantile-based flattened logistic distribution has been studied. Some classical and quantile-based properties of the distribution have been obtained. Closed form expressions of L-moments, L-moment ratios and expectation of order statistics of the distribution have been obtained. A quantile-based analysis concerning the method of matching L-moments estimation is employed to estimate the parameters of the proposed model. We further derive the asymptotic variance–covariance matrix of the matching L-Moments estimators of the proposed model. Finally, we apply the proposed model to simulated as well as two real life datasets and compare the fit with the logistic distribution. 相似文献

Cet article montre comment l'application d'une méthode d'analyse biographique d'interaction à un domaine où l'interaction paraît évidente — activité féminine et fécondite — ouvre des perspectives nouvelles. En effet, les limites qui apparaissent lors de cette analyse conduisent les auteurs à conclure que ce n'est pas en raffinant les méthodes mais plutôt la collecte que l'on parviendra à progresser dans ce domaine. Le problème des interactions de l'activité et de la fécondité semble mal posé avant même le recours à la méthode. Cela justifie la nécessité de saisir le travail féminin comme concept unifié ne dissociant pas la sphère domestique et la sphère rémunérée. Cela conduit les auteurs à dégager quelques principes de collecte mieux adaptés aux préoccupations récentes dans ce domaine: des données biographiques sur le travail féminin. L'interaction collectée à sa source se prêterait alors à une analyse biographique plus révélatrice que celle qui confronte deux processus sans en évaluer les modalités changeantes.This article demonstrates how life event history analysis applied to the interaction between fertility and female economic activity can lead to new perspectives in the analysis of this complicated relationship. The authors identify limits to the analysis of the interaction given the anticipatory nature of behaviour. They conclude that progress in this field requires not the refinement of methods but rather a fundamental change in the approach to the data collected. If fertility and employment are considered separately, a problem is created even before the methods of analysis are applied. They recommend a conception of women's work as a whole, a conception that does not dissociate domestic and paid work. The authors go on to identify ways of improving the relevance of data collection to contemporary issues in the life history analysis of women's work. They argue that data on the interaction, collected at its source, would yield a more revealing life history than that which sees domestic work and paid work as separate spheres, and fails to take account of changes in their relationship. 相似文献

Dietary and Inhalation Intake of Lead and Estimation of Blood Lead Levels in Adults and Children in Kanpur, India 总被引:1,自引:0,他引:1
This research was initiated to study lead levels in various food items in the city of Kanpur, India, to assess the dietary intake of lead and to estimate blood lead (PbB) levels, a biomarker of lead toxicity. For this purpose, sampling of food products, laboratory analysis, and computational exercises were undertaken. Specifically, six food groups (leafy vegetables, nonleafy vegetables, fruits, pulses, cereals, and milk), drinking water, and lead air concentration were considered for estimating lead intake. Results indicated highest lead content in leafy vegetables followed by pulses. Fruits showed low lead content and drinking water lead levels were always within tolerable limits. It was estimated that average daily lead intake through diet was about 114 microg/day for adults and 50 microg/day in children; tolerable limit is 250 microg/day for adults and 90 microg/day for children. The estimated lead intakes were translated into the resultant PbB concentrations for children and adults using a physiologically-based pharmacokinetic (PBPK) model. Monte Carlo simulation of PbB level variations for adults showed that probability of exceeding the tolerable limit of PbB (i.e.,10 microg/dL) was 0.062 for the pre-unleaded and 0.000328 for the post-unleaded gasoline period. The probability of exceeding tolerable limits in PbB level was reduced by a factor of 189 in the post-unleaded scenario. The study also suggested that in spite of the introduction of unleaded gasoline, children continue to be at a high risk (probability of exceeding 10 microg/dL = 0.39) because of a high intake of lead per unit body weight. 相似文献

A Macro-Economic Framework for Evaluation of Cyber Security Risks Related to Protection of Intellectual Property 总被引:1,自引:0,他引:1
The article is based on the premise that, from a macro-economic viewpoint, cyber attacks with long-lasting effects are the most economically significant, and as a result require more attention than attacks with short-lasting effects that have historically been more represented in literature. In particular, the article deals with evaluation of cyber security risks related to one type of attack with long-lasting effects, namely, theft of intellectual property (IP) by foreign perpetrators. An International Consequence Analysis Framework is presented to determine (1) the potential macro-economic consequences of cyber attacks that result in stolen IP from companies in the United States, and (2) the likely sources of such attacks. The framework presented focuses on IP theft that enables foreign companies to make economic gains that would have otherwise benefited the U.S. economy. Initial results are presented. 相似文献

Interaction with employees is essential for organizational leaders. If executives do not communicate well, important processes like giving feedback, setting goals or guiding change processes can nevertheless lead to resistance from subordinates when communication is received as more threatening than challenging. Conveying messages in ways that provoke challenge instead of threat appraisals can be achieved via employee-oriented communication, but this may require taking peoples’ differing motivational orientations into account. This is because motivational orientations partially determine what kind of information is motivating to us, which goals and strategies we prefer, and how we deal with changes. In this regard, Regulatory Focus Theory (Higgins 1997) compares the gain- and success-sensitive promoter with the loss- and failure-sensitive preventer. This article applies this theory to the organizational psychological context and outlines practical implications for managers. The goal of the piece is to provide managers a leadership tool that acknowledges the diversity of peoples’ motivational styles and by that revealing a need-oriented and more efficient way in communication with subordinates. 相似文献

This article evaluates a program between students at a primary school and aged care residents. The aim of the program was to increase respect and appreciation between the groups. Visiting programs between children and the elderly are well documented, and assumes that the contact will benefit both groups. However the research is contradictory. To ensure that this program was achieving its goals, pre-post test data using the Children’s Perceptions of Aging and Elderly test was collected. Significant improvements in attitude were seen in two items. Overall, there was an improvement in attitude in 12 of the 18 instrument items. 相似文献
