A longitudinal data set is employed to explore the sources of stability and change in young adults' health beliefs and behavior concerning drinking, diet, exercise, and wearing seat belts. There is substantial change in the performance of health behaviors during the first three years of college, and peers have a strong impact on the magnitude of that change. In total, however, parents are much more important than peers as sources of influence over these beliefs and behaviors. Of the various social influence processes considered, the direct modeling of behavior appears to be the most important avenue of influence for both parents and peers. These data, along with previous papers in our research program, suggest a pattern of gradually increasing parental influence on their children's health beliefs and behavior while the children are living at home, and the persistence of that influence at least through the college years.  相似文献

Non-profit industrial development organisations (NIDOs) represent a common but little studied community response to widespread deindustrialisation in the United States. These non-profits are organised as chartered not-for-profit corporations, public authorities or agencies of local government. Most receive at least some public funding to promote local industrial development. Thus, a key issue is how accountable NIDOs are to the public they have been created to serve. Data from national surveys of NIDO executive directors in 1984 and 1994, as well as a survey of six case study boards of directors, suggest that public accountability is an increasingly important concern among NIDOs. Public hearings, efforts to diversify the boards in terms of gender and race, and connections to community development corporations and other local organisations are among the ways NIDOs attempt to be accountable to the general public. Although few women or racial minorities serve on NIDO boards, those boards with representation of these groups tend to be more concerned with public accountability. Boards containing public officials tend to be less concerned, presumably because their presence makes the NIDOs more directly accountable as a result of the participation of elected public representatives.  相似文献

This paper discusses the opposition of civil society to nonferrous metals mining in Montana. The mineral resources and mining history of Montana are discussed, as is the vibrant civil society of that state. Montana’s civil society has opposed mining due to its environmental effects, particularly upon areas of high conservation value. This opposition has involved litigation and the implementation of a ban on the use of cyanide by the mining industry. The paper concludes with a discussion of whether this opposition to mining has damaged the economy of the state and Montana’s future as an example of the “New West,” wherein amenities based growth act as the principal agent of economic activity.  相似文献

As a result of the Chernobyl nuclear power plant accident in 1986, large forested areas in Europe were contaminated by radionuclides. Extensive societal pressure has been exerted to decrease the radiation dose to the population and to the environment. Thus, in making abatement and remediation policy decisions not only economic costs, but also human and environmental risk assessment are desired. Forest remediation by organic layer removal, one of the most promising cleanup policies, is considered in this paper. Ecological risk assessment requires evaluation of the radionuclide distribution in forests. The FORESTPATH model(1,2) is used for predicting the radionuclide fate in forest compartments after deposition as well as for evaluating the application of the remedial policy. Time of intervention and radionuclide deposition profile was predicted as being crucial for the remediation efficiency. Risk assessment conducted for a critical group of forest users in Belarus shows that consumption of forest products (berries and mushrooms) leads to about 0.004% risk of a fatal cancer. Cost-benefit analysis for forest cleanup suggests that complete removal of organic layer is too expensive for application in Belarus.  相似文献

'Stereotype threat' refers to the state of psychological discomfort people experience when confronted by an unflattering reputation in a situation where that reputation can be confirmed by one's behavior. Once aroused, stereotype threat can have a number of disruptive effects, among them the short-term impairment of intelligent thought and academic achievement. Over time, it can prompt defensive adaptations that have far-reaching effects, such as disengagement from activities or domains where the stereotype is relevant, which in turn can lead to impaired intellectual development. Stereotype threat thus can result in a self-fulfilling prophecy whereby a person comes to resemble his or her reputation, living up or down to social expectations. This article reviews the development of the stereotype threat construct from Steele and Aronson's (1995 ) original demonstration to investigations of its generality and mediators and to more recent studies focusing on strategies for reducing its negative effects.  相似文献

Research indicates that closeness of the father‐child bond following parental divorce is associated with better outcomes for children and adolescents. Unlike other investigations, this study takes a long‐term developmental approach to understanding stability and change in postdivorce father‐adolescent relationship closeness. Drawing on Add Health data (n = 483), we examine factors that explain (a) why some high‐quality father‐adolescent relationships remain the same after divorce whereas others decline, and (b) why some low‐quality relationships are stable following divorce whereas others improve. High mother‐offspring relationship quality and offspring feelings of well‐being prevented close father‐offspring relationships from deteriorating. Offspring’s childbearing and cohabitation following parental divorce increase closeness in father‐offspring relationships that were not close prior to divorce. Although a majority of offspring experienced a decline in closeness following divorce, results from this study show that some very close father‐offspring relationships are maintained and some poor relationships become closer.  相似文献

Legalizing abortion can either increase or decrease investments in children's human capital. This article finds that abortion increases the number of out-of-wedlock births. Using data that more directly links the criminal with age when the crime was committed, not age when arrested, and fixing the assumption in previous research that no abortions took place prior to the Roe v. Wade decision in the 45 states affected by that decision, we find consistent significant evidence that legalizing abortions increased murders by over 7%. Linear estimates indicate that legalization increased total annual victimization costs by at least $3.2 billion. ( JEL K42, K14, J24)  相似文献
