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

The advent of public-sector managerialism has brought with it a new principle of police accountability in Western democracies such as Australia and Britain. The new accountability gives emphasis to managerial rather than legal or public-interest standards, favours external oversight combined with self-regulation rather than centralized control, and promotes risk management rather than rule enforcement. This article makes use of the experience of an Australian police force to show that the new accountability has not been successful in holding police accountable, while elements of the old accountability have re-emerged to dominate public debates. It is argued that in the area of police governance, the neo-liberal state does not necessarily pursue a coherent strategy of 'acting at a distance' (cf. Miller and Rose 1990), partly because of the inability of accountability technologies to deliver substantially the promised policy outcomes and partly because of the sensitivity of its political arm to the public's moral outrage against corruption (cf. Garland 1996).  相似文献

This study expands immigrant social network theory and examined employment patterns in the garment industry in Los Angeles, California, among Latino workers employed by Asian immigrant entrepreneurs. The study determined that a large percentage of immigrant employees found their jobs through the immigrant economy. Entrepreneurship increased the supply of local jobs and expanded the economy at destination at no expense to natives. Immigrant entrepreneurs bought firms from nonimmigrant owners or started new ones with an immigrant labor supply. Massey's index is flawed due to its exclusion of the role of entrepreneurs. Migration networks facilitate entrepreneurship, but some ethnic groups have fewer entrepreneurs, such as Mexicans and Central Americans. A 1993 Los Angeles survey identified 3642 garment factories in its county. Mean employment was 27.1 persons. The garment industry was the 4th largest industry in the area in 1996, with 98,700 employees. It represented 6% of all wage and salary employees in the City and 5.5% of the immigrant labor force in the County in 1990. 93% of garment workers in 1990 were immigrants. It is estimated that 51% of garment factory owners were Asians; most employees were Latinos. Census figures on sewing machine operators indicated 47.3% of owners were Whites and 42.45 were Asians. 53.3% of employees were other ethnic groups, 14.5% were Asians, and 32.2% were Whites. It is estimated that 47.2% of total employment was due to the immigration economy. 71.5% of the total employment in the garment industry was in the immigrant sector.  相似文献

As of 1995, there were 5.3 million small-employer firms (100 or fewer employees) in the United States. These small firms employed 38.0 million individuals, representing 38 percent of all employment. Therefore, low retirement plan coverage among small employers directly affects a sizeable fraction of the national work force. There are a number of reasons why more small employers do not offer retirement plans. Cost and administration-related issues do matter, but for many small employers these take a back seat to other issues. For some, the main driver is the financial reality of running a small business: Their revenue is too uncertain to commit to a plan. For others, the most important reasons for not sponsoring a plan are employee-related, e.g., the workers do not consider retirement savings to be a priority, or the employer's work force has such high turnover that it does not make sense to sponsor a plan. Many nonsponsors are unfamiliar with the different retirement plan types available to them as potential plan sponsors, especially the options created specifically for small employers. For example, most nonsponsors said they have never heard of (36 percent) or are not too familiar with (20 percent) SIMPLE plans for small businesses. Fifteen percent of small employers report that they are very likely to start a plan in the next two years, while 24 percent say this is somewhat likely. Nonsponsors report that the two items most likely to lead to serious consideration of sponsoring a plan are an increase in profits (69 percent) and business tax credits for starting a retirement plan (67 percent). Major drivers of low retirement plan sponsorship among small employers are who they employ and the uncertainty of revenue flows. While issues of administrative cost and burden matter, they are only part of the puzzle. Therefore, the solution is not simply "build it and they will come," by creating simpler and simpler retirement plans geared to small businesses. Rather, it is build it and they will come once the business reaches a certain level of profitability and stability, and once retirement planning and saving are more of a priority for the small employer's workers.  相似文献

This Issue Brief provides data on employment-based health insurance, with a discussion of recent trends and how sponsorship rates, offer rates, coverage rates, and take-up rates vary for different workers. Other sections examine reasons why workers do not participate in employment-based health plans, alternative sources of health insurance, and uninsured workers. In 1997, 83 percent of the 108.1 million wage and salary workers in the United States were employed by a firm that sponsored a health plan. Of those workers, 75 percent were offered coverage, and 62 percent (or 67.5 million workers) were covered by that plan. Of those workers who worked for an employer that offered them a health plan, 83 percent participated in the plan. Sponsorship rates have barely changed in the last 11 years. In 1988, 83 percent of wage and salary workers reported that their employer sponsored a health plan. This declined slightly to 82 percent in 1993 but had increased to 83 percent by 1997. Offer rates significantly changed between 1988 and 1997. In 1988, 82 percent of workers reported that they were eligible for health insurance through their employer. By 1993, the percentage of eligible workers declined to 74 percent, and it has only slightly increased since then to 75 percent in 1997. In 1997, 40.6 million American workers did not have health insurance through their own job. Forty-five percent of the workers without coverage were employed at a firm where the employer did not provide health insurance to any workers. Thirty-three percent of the workers without coverage were offered coverage but declined it. Twenty-two percent of the workers without coverage were employed in a firm that offered health insurance to some of its workers, but certain workers were not eligible for the health plan. The 13.7 million workers who were offered coverage but declined it gave a number of reasons for doing so. In the majority of cases (61 percent), the worker was covered by another health plan. Of the remainder, 20 percent reported that health insurance was just too costly. Overall, 41 percent of the 40.6 million workers who were not participating in an employment-based health plan through their own employer had coverage through a spouse. However, 42 percent of the 40.6 million workers who declined their employers' health plan or who were not offered health insurance from their employer were uninsured.  相似文献

The Physicians' End-of-Life Care Attitude Scale (PEAS) was developed as an outcome measure for palliative care education. PEAS assesses the willingness of medical trainees to care for dying patients. Sixty-four Likert-type questions were created on the basis of discussions with focus groups of medical trainees, then administered to sixty-two medical students and residents. Total PEAS scores as well as personal preparation and professional role subscales (where higher scores indicated greater concern) possessed excellent internal consistency and reliability. In addition, there were substantial correlations between PEAS scores and the CA-Dying scale, a measurement of laypersons' fears about interacting with dying persons. Thus, PEAS adequately assesses the unique communication concerns of physicians in training regarding working with dying persons and their families. Correlations between PEAS scores and age were negative, while those who had experienced the death of a loved one had higher PEAS scores than those who did not. This suggests that for some persons, life experiences may lessen difficulties in dealing with dying persons, while for others, personal losses may exacerbate such concerns. The utility of PEAS in evaluating the efficacy of palliative care education as well as its potential to measure medical trainee's willingness to care for the terminally ill is discussed.  相似文献

With health networks searching for additional market share and with a projected 30.2 million to be enrolled in Medicaid HMOs by 2000, more health executives will be weighing various strategies of how to attract qualified physicians to practice in poor inner-city and rural areas. Most frequently cited as solutions are supplying more physicians, encouraging more medical school graduates to pursue primary care residencies, and modifying the number of international medical graduates entering U.S. residency programs. Part I of this article, which appeared in the November/December issue of The Physician Executive, reviewed the efficacy of these approaches. The second part explores a more pragmatic option: to simply improve the working conditions and pay substantially more to physicians who practice in "less desirable" locations. Although this idea is consistent with economic principles, drawbacks must be considered, such as: (1) the American taxpayers' reluctance to finance a more costly health care delivery system for the poor; (2) the inherent conceptual difficulties of a capitated Medicaid HMO serving as the linchpin for organizing, financing, and delivering care for the underserved; and, (3) many providers being expected to react in a fairly litigious manner to such an approach.  相似文献

Sometimes conducting an experiment to ascertain the state of a system changes the state of the system being measured. Kahneman & Tversky modelled this effect with support theory. Quantum physics models this effect with probability amplitude mechanics. As this paper shows, probability amplitude mechanics is similar to support theory. Additionally, Viscusi's proposed generalized expected utility model has an analogy in quantum mechanics.  相似文献
