In the past decade, social scientists and bioethicists have produced a significant body of work tracking the technical, legal, ethical, and sociocultural development and implications of human egg freezing. What began as a treatment to “preserve” the fertility of cancer patients has transformed into a technology enabling delayed childbearing. We provide an overview of four research areas that have received the most attention in the sociological and anthropological literature of egg freezing: medicalization, gender, temporality and risk, and markets. What emerges from much of the research is the sense that egg freezing has become entangled with cultural imperatives to take future-oriented responsibility for one's own health, financial, social, and reproductive needs through self-management, risk reduction, calculation, and optimization. Throughout, we consider the implications of this novel reproductive technology within national and transnational “reproflows” that stratify reproduction along raced and classed lines. 相似文献

Although a wide list of classes of space–time covariance functions is now available, selecting an appropriate class of models for a variable under study is still difficult and it represents a priority problem with respect to the choice of a particular model of a specified class. Then, knowing the characteristics of various classes of covariances, and their auxiliary functions, and matching those with the characteristics of the empirical space–time covariance surface might be helpful in the selection of a suitable class. In this paper some characteristics, such as behavior at the origin, asymptotic behavior, nonseparability and anisotropy aspects, are studied for some well known classes of covariance models of stationary space–time random fields. Moreover, some important issues related to modeling choices are described and a case study is presented. 相似文献

The purpose of this research is to examine successful aging in three Asian countries, Indonesia, Sri Lanka and Thailand, using data from the WHO regional studies of Health and Social Aspects of Aging. Successful aging is defined as having no ADL difficulties, and at most, one Nagi difficulty. For the most part, the results are similar to those using more developed populations in that gender, age, no morbid conditions, positive attitude toward one's own aging and the ability to manage money are all correlated with successful aging. An interesting finding is that for the least developed country, Indonesia, being an unskilled worker is significantly associated with increased odds for successful aging. The final section of the paper discusses the theoretical implications regarding a disability transition for elderly populations as countries develop. We also focus on the current political and economic situations in the countries under study, and consider the possible impacts on elderly health. 相似文献

Outbreaks of influenza represent an important health concern worldwide. In many cases, vaccines are only partially successful in reducing the infection rate, and respiratory protective devices (RPDs) are used as a complementary countermeasure. In devising a protection strategy against influenza for a given population, estimates of the level of protection afforded by different RPDs is valuable. In this article, a risk assessment model previously developed in general form was used to estimate the effectiveness of different types of protective equipment in reducing the rate of infection in an influenza outbreak. It was found that a 50% compliance in donning the device resulted in a significant (at least 50% prevalence and 20% cumulative incidence) reduction in risk for fitted and unfitted N95 respirators, high‐filtration surgical masks, and both low‐filtration and high‐filtration pediatric masks. An 80% compliance rate essentially eliminated the influenza outbreak. The results of the present study, as well as the application of the model to related influenza scenarios, are potentially useful to public health officials in decisions involving resource allocation or education strategies. 相似文献

Twelve of the novels of Charles Dickens provide a sample of 349 characters whose occupational achievement and mobility are investigated. The mobility patterns indicate more inheritance than in the United States. This cannot be accounted for by education, material inheritance, or morality (being a good or bad person). A model of quasi-perfect mobility, taking all diagonal frequencies as given, more closely represents the patterns. Determinants of achievement considered are social origins, number of siblings, education, marital status, morality. The characters from large families do better occupationally than those from small. Education functions primarily to redistribute success. The married are superior to the unmarried, with marriage functioning not as a selective mechanism, but exerting causal impact of its own. The evil are rewarded in this life. The basic path model of the stratification system of Dickens is similar to that of the United States. 相似文献

I attempt to show how my ideas about bureaucracy and Mexican American culture are a product of my life history and how I worked
out key features of these ideas in teaching sociology at a small university. This was made possible because strategic sponsors
helped me as an “outsider” to become a kind of “insider” within that social milieu.
Her fields of interest are bureaucracy, family, social psychology and race and ethnic relations. She is currently writing
a monograph on Mexican American family life. 相似文献
