A method is presented for analysing maternity history data to provide period estimates of parity progression ratios, birth intervals and related indices. This is applied to a sample of the marriage and maternity histories from the Census of England and Wales of 1971 and shows: (a) a general increase through the 1950s and into the 1960s in period estimates of marriage and parity progression ratios, especially in the progression from first to second birth; (b) a general acceleration of fertility with, again, the second birth interval becoming particularly short and compact; and (c) very steep declines in third and fourth birth progression ratios from the mid-1960s. Birth interval distributions altered during the period examined. Decomposition of a progression-based total fertility index shows change in the ratios for lower birth orders to have dominated the fertility upswing and declines in ratios for higher birth orders to have initiated the subsequent decline.  相似文献

Methods for a sequential test of a dose-response effect in pre-clinical studies are investigated. The objective of the test procedure is to compare several dose groups with a zero-dose control. The sequential testing is conducted within a closed family of one-sided tests. The procedures investigated are based on a monotonicity assumption. These closed procedures strongly control the familywise error rate while providing information about the shape of the dose-responce relationship. Performance of sequential testing procedures are compared via a Monte Carlo simulation study. We illustrae the procedures by application to a real data set.  相似文献

The history of public health changes is taken forward from 1900 to 1950. This was a period of important development in a population in which most ofthe adult members had at the outset of the period experienced compulsory primary education; when the full effects of industrial development had made their mark on the nation's health and, at last, on the public conscience; when the force of social and economic factors in producing and perpetuating disease was becoming appreciated; and when community responsibility for the health and welfare ofthe individual was becoming accepted. Not surprisingly, great improvements were made in the scope of preventive and curative services and in their accessibility. But the most important factor in the improvement of the national health was the steady rise in the level of living of the population, especially during the last two decades of the period.  相似文献

Today, young adults are expected to decide between educational, vocational, and job options and to make the best choice possible. Career literatures emphasize the importance of young adults' career decision making but also acknowledge the problems related to making these decisions. The authors argue that career counselors could support clients' intuitive processing of career information and help their clients to develop a positive and flexible view of the self and the environment while diminishing concerns about accountability for and irreversibility of career decisions. The authors argue that career adaptability rather than decision making should become the focal concept of career theory and practice.  相似文献

Revolutionary Horizons, by Forrest Hylton and Sinclair Thomson,is a highly readable work that contributes to understandingthe recent events that have placed Bolivia, once erased fromthe map by Queen Victoria following the expulsion of her emissaryin the nineteenth century, in the spotlight of observers ofprogressive movements around the world. With an insightful introductionby Adolfo Gilly, the book provides an accessible analysis ofthe events that led to the inauguration of Evo Morales, thefirst indigenous president in Bolivian history, in January 2006,ending the epoch of Andean apartheid.

Abstract

The French intellectual Georges Bataille (1897–1962) developed base materialism in his work during the late 1920s and early 1930s as an attempt to break with all existing materialism. This essay is an explication of base materialism and its radical implications for contemporary theory. Bataille argues for the concept of an active base matter that disrupts the opposition of high and low and destabilises all foundations. Then he attempts to use this to develop a radical libertarian Marxism, opposed to both Stalinism and fascism. Although it provided a critique of the emphasis in Marxism on production, the active flux of base matter could not be contained in a political discourse. This means that Bataille's thought has an impact beyond the political and into the wider domain of theory. One example of this is the influence of base materialism on Derrida's deconstruction, and both share the attempt to destabilise philosophical oppositions by means of an unstable ‘third term’. This explains why Bataille's materialism does not appear as conventionally materialist, and why it has had little impact within contemporary materialism. Despite attempts to force base materialism into the mold of a new form of materialism it disrupts conventional materialism and the ‘radical’ politics that often goes with it. Bataille destroys the promise of liberated spaces and offers a more radical and disorienting freedom which inscribes instability into all discourses. It is this that defines the importance and necessity of Bataille's base materialism today.  相似文献

The purpose of this study was to validate and expand on Y. B. Chung's (2001) models of work discrimination and coping strategies among lesbian, gay, and bisexual persons. In semistructured individual interviews, 17 lesbians and gay men reported 35 discrimination incidents and their related coping strategies. Responses were coded based on Chung's models. Results supported the validity of the Work Discrimination model and two coping strategy models (Vocational Choice and Identity Management). The Discrimination Management coping strategy model was expanded. Implications for practice and research are discussed.  相似文献
