Effects of neighborhood walkability on healthy weight: assessing selection and causal influences

Studies that examine the relationship between neighborhood characteristics and weight are limited because residents are not randomly distributed into neighborhoods. If associations are found between neighborhood characteristics and weight in observational studies, one cannot confidently draw conclusions about causality. We use data from the Utah Population Database (UPDB) that contain body mass index (BMI) information from all drivers holding a Utah driver license to undertake a cross-sectional analysis that compares the neighborhood determinants of BMI for youth and young adults. This analysis assumes that youth have little choice in their residential location while young adults have more choice. Our analysis makes use of data on 53,476 males and 47,069 females living in Salt Lake County in 2000. We find evidence of residential selection among both males and females when BMI is the outcome. The evidence is weaker when the outcomes are overweight or obesity. We conclude that studies that ignore the role of residential selection may be overstating the causal influence of neighborhood features in altering residents’ BMI.     

Are we investing less in the next generation? Historical trends in time spent caring for children

Historical and current data sets are used to trace the time married women and men spend caring for their own children on a daily basis. The data are also used to estimate the total time parents spend in raising two children to the age of 18. The analysis is restricted to primary child care time; i.e., the actual, direct administration of personal care, including physical care (feeding, bathing, dressing, putting to bed) and such other direct personal care as teaching, chauffering, supervising, counseling, managing, training, amusing, and entertaining. Secondary parental child care time is not studied. Although white married women spent about. 56 hours per day per child in primary child care in the 1924–1931 period, by 1981, the time had decreased to about 1.00 hour per day per child. Married men spent 0.25 hours per day per child in 1975, the first year for which national data exists. By 1981, this figure had increased to 0.33 hours per day per child. Raising two children to age 18 required about 5,789 hours of a white, employed, married woman's time and 14,053 hours of a white, unemployed, married woman's time in 1981. Husbands of white, employed married women spent about 1,500 more hours in raising two children to age 18 than the husbands of white, unemployed married women.His research interests include the economics of family time use, household production, consumption, and demand.Her research interests include household production, family structure and family well-being, and family policy.     

Measuring Housework in Time Use Surveys

A methodology is devised to decompose the error in the measurement of housework time in surveys. Using data from the Panel Study of Income Dynamics (PSID) and the Americans' Use of Time Survey, we estimate that a telephone (mail) survey rather than an interview survey leads to a mean underestimation of 60 (30) min/week for women and 18 (13) min for men. We also find that the errors created by using a narrow definition of housework leads to an underestimation of between 10 and 12 h/week for both men and women in the PSID.

The Syndrome of Group-Focused Enmity: The Interrelation of Prejudices Tested with Multiple Cross-Sectional and Panel Data

Different types of prejudice are usually treated as separate constructs. We propose that they constitute a syndrome of group-focused enmity (GFE), that is, they are related to each other and share a common core that is strongly predicted by a generalized ideology of inequality. Furthermore, GFE components are supposed to have similar predictors and outcomes. An empirical test is presented using structural equation modeling on the syndrome, its causes, consequences, and structural stability over time. The study relies on three German cross-sectional probability samples (each N = 2,700) and a related panel study (2002, 2003, and 2004). The idea of a GFE syndrome is strongly supported. Future research is discussed, as well as alternative approaches of a common prejudice factor .     

The role of economic and demographic factors in explaining time-use of single and married mothers

The number of households headed by single mothers has been increasing in recent years. Yet, little is known about how this growing segment of the population differs, if at all, from married mothers in their time allocation patterns. In the study reported here, a system of time allocation equations based on household production theory is estimated for both married and single mothers. The results indicate that married and single mothers make different decisions about how to allocate their time to household production, child care, leisure, and paid work. Specifically, single and married mothers responded differently to a change in their shadow wage rates, unearned income, paid child care, and the ages of the children in each of the estimated equations.A portion of this project was funded by the Wisconsin Agricultural Experiment Station.

The roles of role strain,economic resources and time demands in explaining mothers' life satisfaction

Time diary and questionnaire data from mothers who are full-time homemakers, members of dual-earner households, and heads of single-parent households are analyzed to determine the influence of family structure, economic resources, and time demands on their life satisfaction. The multivariate analysis reveals that family structure is moderately related to mothers' satisfaction with progress in life but not to satisfaction with life as a whole. Mothers' satisfaction with life as a whole does vary with their life cycle stage, economic situation, and their use of time.Her research interests include time use of household members and CADD education for interior design students.

Does housework matter anymore? The shifting impact of housework on economic inequality

In recent years, American women’s housework time has declined while American men’s housework time has risen. We examine how these changes have affected economic inequality in the United States. Using time-diary data from the Time Use in Economic and Social Accounts, 1975–1976 (N = 1,484) and the American Time Use Survey, 2003 (N = 5,534), we value adults’ housework using two alternative methodologies and assess its influence on households’ real access to goods and services in both years. Results suggest that housework reduces economic inequality in both years. But, between 1975–1976 and 2002–2003, overall economic inequality rose largely because of the growing wage inequality and also, in part, because of growth in housework inequality. Socio-demographic change partially inhibited the overall growth in economic inequality.

Acculturation and Prejudice in Germany: Majority and Minority Perspectives

This article explores the connections between prejudice and specific attitudes toward acculturation in Germany. Results of surveys confirm the hypothesis that prejudice is related to ideologies of assimilation and segregation among majority- group members. Moreover, experimental and correlational studies indicate that these attitudes are linked to discriminatory behavior. Further analyses of studies with ethnic minorities prove that prejudice and acculturation are linked within minority groups as well. Additionally it is shown that prejudice is functional in order for minorities to acculturate. These studies confirm the impression that there is a close link between macrosocial and microsocial levels of coping with migration.
