This study tests the two assumptions underlying popularly held notions that maternal employment negatively affects children because it reduces time spent with parents: (1) that maternal employment reduces children’s time with parents, and (2) that time with parents affects child outcomes. We analyze children’s time-diary data from the Child Development Supplement of the Panel Study of Income Dynamics and use child fixed-effects and IV estimations to account for unobserved heterogeneity. We find that working mothers trade quantity of time for better “quality” of time. On average, maternal work has no effect on time in activities that positively influence children’s development, but it reduces time in types of activities that may be detrimental to children’s development. Stratification by mothers’ education reveals that although all children, regardless of mother’s education, benefit from spending educational and structured time with their mothers, mothers who are high school graduates have the greatest difficulty balancing work and childcare. We find some evidence that fathers compensate for maternal employment by increasing types of activities that can foster child development as well as types of activities that may be detrimental. Overall, we find that the effects of maternal employment are ambiguous because (1) employment does not necessarily reduce children’s time with parents, and (2) not all types of parental time benefit child development. 相似文献

Associations among (a) self-disclosures between early adolescent siblings, (b) emotional understanding, and (c) relationship warmth were investigated. Grade 5–6 children (M age = 11.5 years) were interviewed concerning the incidence of disclosures to closest-in-age siblings (20 = older, 20 = younger), feelings regarding disclosing (or not), and sibling relationship quality. Warmth was measured with the Sibling Relationship Questionnaire (Furman & Buhrmester, 1985) and emotional understanding was assessed with the Hypothetical Relationships Picture Task (adapted from Schneider, 1989, & Aquan-Assee, 1992). Hierarchical multiple regressions indicated self-disclosure was positively associated with feeling good about sharing and negatively associated with reports of not trusting or not receiving emotional support from their sibling. Sibling relationship warmth was a key characteristic associated with both emotional understanding and self-disclosure; female target children demonstrated greater emotional understanding. Warmth, but not emotional understanding, was associated with self-disclosure. Findings are discussed in light of the importance of links between affective relationships and children's social-emotional understanding. 相似文献

The simplified Conjoint Expected Risk (CER) model by Holtgrave and Weber posits that perceived risk is a linear combination of the subjective judgments of the probabilities of harm, benefit, and status quo, and the expected harm and benefit of an activity. It modifies Luce and Weber's original CER model—that uses objective information to evaluate financial gambles—to accommodate activities such as health/technology activities where values of the model variables are subjective. If the simplified model is a valid modification of the original model, its performance should not be sensitive to the use of subjective information. However, because people may evaluate information differently when objective information is provided to them than when they generate information on their own, the performance of the simplified CER model may not be robust to the source of model-variable information. We compared the use of objective and subjective information, and results indicate that the estimates of the simplified CER model parameters and the proportion of variance in risk judgments accounted for by the model are similar under these two conditions. Thus, the simplified CER model is viable with activities for which harm and benefit information is subjective. 相似文献

This study investigated visual dominance and visual egalitarianism of men and women (N = 94; 17 teams) in team meetings at diverse workplaces. Two novel gaze-related measures were developed: (a) a group visual dominance ratio (group-VDR) assessing each member’s visual dominance vis-à-vis all other members, and (b) a gaze distribution index (GDI) assessing each member’s visual egalitarianism to all group members. Multilevel analyses were conducted to account for
influences of the team members’ sex and status on the individual level and for influences of sex and status composition of
the teams, and the team leaders’ sex on the group level. Results suggested that high-status individuals displayed more visual
dominance than low-status individuals. The significant interaction of individuals’ sex and status indicated that the positive
relationship of status and visual dominance applied particularly to women. The more women in a team, the more visual dominance
was displayed. The team leader’s sex significantly influenced visual egalitarianism: Gaze distribution was less egalitarian
when the team leader was male. 相似文献

During the nineteenth century periodic fluctuations in industrial activity, strikes and lock-outs which accompanied the struggle of unions for recognition, and the ever increasing consciousness of the industrial worker that one serious trade setback could wipe out the savings of his lifetime, were important ‘pushes’ to emigration from the United Kingdom. The British trade unions responded to this ‘push’ from their own members and from thousands of unorganized workers for relief through emigration. Contrary to the statements of historians of the English trade-union movement, emigration was not a project of British trade unions in the 1850 decade only; in fact, most of the unions in England's basic industries, mining, iron, textiles and engineering, as well as in many other smaller industries such as glass, cutlery and the building trades, looked upon emigration as necessary to improve the standard of life of the English workers. This viewpoint was natural to the ‘New Unionists’ of the 1850's, who accepted the principle that supply and demand regulated wages and prices. The trade unions, however, disapproved of emigration to the United States where workers would go to a rival trade; such emigration could not diminish the absolute number of workers in the industry. Instead, they advocated emigration to farms in the British colonies; but, nevertheless, most of the persons aided by English trade unions to emigrate went to the United States. The hesitancy of skilled workers to leave a familiar occupation appeared to be the most important reason for this. Desirable as emigration was to trade unionists in times of trade crises, the leaders met overwhelming difficulties when they tried to use it as a safety valve. In the cotton famine and the iron-trade lock-outs of the sixties, for example, unions had no money to aid emigration, and were forced to seek grants from United States manufacturers to help needy workers to go to America. Although they were relatively helpless in times of crisis, the trade unions assisted emigration during good years, believing that such a policy would ease the severity of the inevitable next crisis. Most of the established unions had regularly operating emigration grants by which members in good standing could receive a sum of money in aid of emigration, usually enough to pay at least one passage to America. This benefit helped some of the most skilled workers and loyal union members to leave England for America. The trade unions, in making these grants, had to adjust the amount of money given to the ‘state of health’ of the union treasury; thus, during crises when the treasuries were low the emigration benefits were often discontinued. As the years passed and the number of British workers in America increased, the unions hesitated to send men abroad during depressions or strikes in the United States. Not only did American workmen complain of such competition, but also English workers disliked to see men whom they had previously assisted to ‘take their labour abroad’ return home. From 1850 until well into the 1880's, when most of the English trade unions were encouraging and aiding emigration, their influence actually was most effective toward that end in times of prosperity in the United States. It was the depression of the eighties and the rise of unions of unskilled workers and leaders who looked for improvement through Socialism rather than through adjusting the supply of labour, which finally eclipsed emigration as a panacea for the English working class. 相似文献

We examine the literature on emotional labor and health care to demonstrate the potential for emotional labor research to inform how social and medical scientists think about health care and how examining healthcare contexts has contributed to the scientific understanding of emotional labor processes. In doing so, we first review the key terms and definitions that are used within the emotion management perspective and evaluate the ways in which power differences have remained largely implicit features of research on emotional labor in healthcare settings. Finally, we explore how the increasing economic rationalization of health care may be influencing the emotional experiences of today's healthcare professionals and the implications of this trend for future research on emotional labor and the health and well-being of care providers and their patients. 相似文献

We describe a one-dimensional probabilistic model of the role of domestic food handling behaviors on salmonellosis risk associated with the consumption of eggs and egg-containing foods. Six categories of egg-containing foods were defined based on the amount of egg contained in the food, whether eggs are pooled, and the degree of cooking practiced by consumers. We used bootstrap simulation to quantify uncertainty in risk estimates due to sampling error, and sensitivity analysis to identify key sources of variability and uncertainty in the model. Because of typical model characteristics such as nonlinearity, interaction between inputs, thresholds, and saturation points, Sobol's method, a novel sensitivity analysis approach, was used to identify key sources of variability. Based on the mean probability of illness, examples of foods from the food categories ranked from most to least risk of illness were: (1) home-made salad dressings/ice cream; (2) fried eggs/boiled eggs; (3) omelettes; and (4) baked foods/breads. For food categories that may include uncooked eggs (e.g., home-made salad dressings/ice cream), consumer handling conditions such as storage time and temperature after food preparation were the key sources of variability. In contrast, for food categories associated with undercooked eggs (e.g., fried/soft-boiled eggs), the initial level of Salmonella contamination and the log10 reduction due to cooking were the key sources of variability. Important sources of uncertainty varied with both the risk percentile and the food category under consideration. This work adds to previous risk assessments focused on egg production and storage practices, and provides a science-based approach to inform consumer risk communications regarding safe egg handling practices. 相似文献

Using a new data set on Swiss cantons since 1890, we analyze how the adoption of proportional representation affects fiscal policy. In line with economic theory, we show that proportional systems shift spending toward broad goods (like education and welfare benefits) but decrease spending on geographically targetable goods (like roads). We find little evidence that proportional representation increases the overall size of government. An analysis of the underlying theoretical mechanisms reveals that proportional representation increases electoral turnout, left‐wing representation, and political fragmentation. These changes in political representation explain a substantial share of the rise in education spending, but a small share of the rise in welfare spending or the decline in road expenditures. 相似文献

The daily diary method was used to examine the daily dynamics of adolescent sleep time, activities, and psychological well‐being among an ethnically diverse sample of over 750 adolescents approximately 14–15 years of age. Studying and stressful demands during the day were modestly but consistently associated with less sleep that evening. Receiving less sleep at night, in turn, was modestly but consistently related to higher levels of anxiety, depressive feelings, and fatigue during the following day. In addition, the daily variability in adolescents' sleep time was notable and just as important for the youths' average levels of daily psychological well‐being as was the average amount of time spent sleeping each night. A small number of ethnic and gender differences emerged in the dynamics of adolescent sleep, activities, and well‐being. Discussion focuses on the importance of examining variability in adolescents' sleep behaviors in order to better understand the implications of sleep for adolescent well‐being and development. 相似文献
