Is a shorter life with more years lived in poor health a defining attribute of the life cycle of disadvantaged groups? Based on the J990 5% Public Use Microdata Survey, we develop life table models of healthy (or active) life for the major racial groups, by sex, in the United States. The analysis underscores the complexity of the relationship between morbidity and mortality in the population. For Asians, longer life is associated with fewer years lived in poor health. In contrast, Native Americans’ relatively longer lives are accompanied by extended periods of chronic health problems. of all racial groups, blacks live the fewest years, and they live a high proportion of those years with a chronic health problem. Hispanics also live substantially fewer years, yet the period of life they spend with a health problem is relatively compressed. Racial differences in the link between morbidity and mortality point to the importance of investigating how chronic diseases and disease prevention and treatment are related to active life across the population subgroups. 相似文献

This paper shows that financial intermediation can influence fertility and labor allocation decisions by raising market wages.
The increase in wages induces some households to abandon “traditional” labor intensive methods of production managed at the
household level and supply labor to “modern” sector firms. Since it is optimal for households in the modern sector to have
fewer children, the labor allocation decision leads to lower national fertility. A panel VAR using financial intermediation,
fertility and industrial employment share data in 87 countries is estimated. The empirical results show that the data are
consistent with the theoretical predictions.

Using the Luxembourg Income Study data we examine married women's dependency on their husbands' earnings in nine Western industrialized
countries: Australia, Belgium, Canada, Finland, Germany, the Netherlands, Norway, Sweden, and the United States. When we examine
the level and degree of dependency, and the labor force participation of married women across countries, the nine countries
fall into the three clusters delineated in Esping-Andersen's welfare states typology. But when we examine the determinants
of the dependency within each country, the clustering disappears. Wives' dependency increases with age, the presence of young
children, and the number of children. It is reduced when wives' labor force participation and education are high relative
to their husbands' and in families that rely more on unearned sources of income. The similarity of patterns across countries
suggests that gender differences in the work-family nexus are deeply entrenched in all countries and continue even in the
face of very active social policy to minize their effects.
This is a revised version of a paper presented at the annual meeting of the American Sociological Association, August 1995,
Washington DC.
Her current research focuses on gender inequality and parents' time allocation between work and family.
She conducts research on various aspects of family demography, including household and family characteristics, co-resident
grandparent families, cohabitation, and child care. With Suzanne Bianchi, she is completing a research monograph on trends
in the American family.
Her research focuses on gender, work, and family issues. 相似文献

This paper reports the results of a preliminary investigation into whether the drinking of alcohol contributes to impaired control of gambling behaviour. The sampling method consisted of a two-phase survey design, collecting data both prospectively within session and retrospectively via a take-home questionnaire. One hundred sixteen people were interviewed while in a gaming venue playing on an electronic gaming machine (egm) of whom 34 men and 11 women also returned take-home surveys. Comparisons of the sample to previous studies suggested that the sample was representative of the population of egm players. Results indicated a consistent theme of alcohol use contributing significantly to impaired control of gambling behaviour, with level of involvement (Corless & Dickerson, 1989) contributing the most significant variance in the independent variables. Limitations of the study are discussed, but the case is argued that this type of process research is essential in better understanding how these two types of popular leisure activities may interact, possibly leading to the previously recorded chronic, excessive alcohol intake and problematic gambling (e.g. McCormick, Russo, Ramirez & Taber, 1984). 相似文献

This paper gives an historical overview of immigration to Thailand since the 1970s and emigration since the 1960s. It describes migration policies since the 1930s. Final discussion focuses on the impact of economic contraction on migration. Immigration to Thailand dates back to the 1760s when a huge wave of Chinese emigrated to Thailand. The flow continued until about 1850 and resumed during 1905-17. The next big waves of immigrants were after 1975, when refugees fled Indochina, and in the 1990s, when migrants flocked from neighboring countries drawn to the booming economy. Thai professionals left in the 1960s for the USA. During the 1980s, many left for work in the Middle East. During the 1990s, Thai migrants moved within the East and Southeastern Asian countries and the USA or Europe, and they included many women and illegal migrants. Emigrants leave as arranged by the government, by employers, by recruitment agencies, and as trainees. The first official act was in 1950 and revised in 1979. Many work permits were approved in the 1990s, especially for unskilled labor. There are supports for Thai migrants abroad, but little is offered to foreigners at home. By 1997, the country's recession led to nonrenewal of many work permits. The 1998 economic crisis led to a new labor policy that deported illegal and unskilled migrant workers in order to create jobs for Thais. Policy encouraged Thais to seek work overseas. 相似文献

1. Services that may be provided by psychiatric-mental health nurses following a disaster include education, intervention, problem solving, advocacy, and referral. 2. Nurses providing disaster mental health services must be flexible and creative. Strong observational skills and teamwork are also essential characteristics in disaster settings. 3. Psychiatric-mental health nurses who wish to receive training for disaster mental health volunteer opportunities should contact their local chapter of the American Red Cross. 相似文献

Factors to explain the rising incidence of depressive symptoms among young women making the transition from home to university life were investigated. A path analysis of data from 213 18- and 19-year-old women entering a large university indicated that negative life events, interpersonally derived social support, self-esteem, and depressive symptoms were significantly related. Negative life events that affected the women's self-esteem (drawn from the women's performance in interpersonal relationships) were most strongly associated with depressive symptoms, and self-esteem derived through efficacy (i.e., taking control and acting assertively) was not associated with negative events. The women in the sample appeared to derive efficacy self-esteem from relationships. An analysis of the data supported developing interventions to improve interpersonal relationships rather than focusing on competence in gaining access to resources. 相似文献

As a result of the ongoing hallucinations and delusions, life at home became "anxious and chaotic" with "lots of stress." Because there was no on-site crisis intervention by professionals, well siblings were sometimes called upon to control the violent behavior and were vigilant and fearful regarding the potential for abuse. Negative symptoms were the most disturbing to well siblings. Siblings need help to understand that social isolation and lack of motivation are symptoms of the illness--not due to "laziness." 相似文献
