This study analyzes the effectiveness of a mass-media radon information and testing campaign conducted in the Washington, D.C. area in the winter of 1988. Although an impressive number of test kits (approximately 100,000) were sold, the ultimate mitigation rates resulting from the campaign were extremely low. Analyses show that low mitigation rates cannot be explained by postulating that people's responses to radon are insensitive to the level of objective risk. They may instead be due to characteristics of the protective response required to reduce radon risk. Radon may be thought of as one of a family of household risks which have risk response profiles that make them particularly difficult for people to manage and remediate. Traditional information campaigns for such risks are likely to be ineffective; instead, they may require regulatory strategies or programs which provide active guidance and assistance. 相似文献

A research model of the impact of a multinational corporations’ (MNC) global strategic orientation on global IT infrastructure was developed using global integration, or the degree to which a global strategy is actually implemented, as a mediator. A “matched pair” survey of 94 MNCs was conducted (two respondents per firm) in order to guard against common source bias. The results showed that the firms that pursue a globally oriented strategy actually enacted these strategies as indicated by a wide-variety of resource flows across national units. The role of the level of global integration as a mediator between global strategic orientation and global IT capabilities was empirically demonstrated. This confirms that a global strategy is not sufficient to ensure that an enabling IT infrastructure will be developed; rather it is the actual level of integration and interdependence that is achieved as a result of the strategy that drives IT infrastructure. The primary areas in which global integration was found to be closely linked to the global IT infrastructure were human resources, which significantly influenced the reach, range, support services and planning of the global IT infrastructure, and information resources which significantly influenced the planning dimension of the infrastructure. These results strongly suggest that the transfer of people among national units creates an information needs “pull” which leads to the development of better IT infrastructure and that the “push” of standardized information also contributes positively. 相似文献

Multi-level intervention, based on an ecological perspective, has been promoted at the preferred model of providing parenting
support to high-risk families. However, parent views regarding such interventions have not been determined. Focus groups consisting
of 24 parents who had recently completed an intensive parenting program yielded results supporting multi-level interventions
but highlighting processes rather than content within such programs as well as the reciprocal effect of particular level interventions.
Processes identified at intervention levels included Affirming Parent Self-Worth, Non-Directive Instruction, Promoting Social Connections, and Empowering Communication. Increased understanding of and attending to processes in intensive intervention with high-risk families is indicated. 相似文献

This article applies leader‐member exchange theory to the study of dyadic relationships between leaders (board chairs and paid executives) and members (volunteer board members) within the boards of Australian voluntary sport organizations. The article specifically examines leader‐member exchanges within a sample of six Queensland State sport organizations and their relationship with board performance. It was found that leadership within voluntary sport organization boards emanates from either board chairs or executives and that when the individuals fulfilling these roles are able to develop a mature working relationship, the board's ability to perform is enhanced. These findings extend our understanding of the importance of leadership roles held by volunteers and paid professionals for the achievement of organizational outcomes. 相似文献

Using data from 453 adolescents in Wave 2 of the National Survey of Families and Households, we examine how multiple dimensions of nonresident father involvement are associated with different dimensions of child well-being. Father-child relationship quality and responsive fathering are modestly associated with fewer externalizing and internalizing problems among adolescents. The quality of the mother-child relationship, however, has stronger effects on child well-being. Nevertheless, even if adolescents have weak ties to mothers, those who have strong ties to nonresident fathers exhibit fewer internalizing problems and less acting out at school than adolescents who have weak ties to both parents. Adolescents are worst off on a range of outcomes when they have weak ties to both their mothers and nonresident fathers. 相似文献

The Americans with Disabilities Act is both a liberal civil rights bill and a labour economics bill meant to increase the employment of disabled persons. It identifies the source of unemployment in discriminatory attitudes of employers and physical barriers in the work environment, and promotes inclusion through the establishment of regulations that are intended to create 'equal opportunity' in the labour market. Such liberal reforms primarily focus on 'irrational' discriminatory attitudes. Operating within an individualist framework, civil rights have not given sufficient attention to structural barriers, which 'rational' business practices, the economic system and class power relationships erect. This paper will both micro- and macro-economic realities of US capitalism, which directly impede disabled peoples' employment and perpetuate a disabling society. The failure of rights legislation to increase disabled people's employment exposes the contradictions of promoting equal opportunity in a class-based (unequal) society. 相似文献

Objective. Some studies of negative campaign advertising's impact argue that a backlash or “boomerang effect” exists. However, the appropriate conceptualization of a boomerang effect might not be an immediate backlash against the sponsor but a delayed response that comes after repeated exposure to negative campaign advertisements. Method. We conducted an experiment using a variation of the pretest‐posttest control group design in which treatment groups were exposed to varying numbers of negative campaign advertisements. Results. There is a parabolic effect of repeated exposure to negative advertisements that is gender specific. Among women, the sponsor initially benefits from an enhanced image but suffers a decline in image when the voters become overexposed to negative advertisements. Conclusion. A reconceptualization of the “boomerang effect” of negative campaign advertising is in order. 相似文献

Romantic relationships constitute an important, but understudied, developmental context for accommodation to pubertal change. Using a nationally representative sample of 5,487 black, white, and Hispanic adolescent females, this study examined associations among body mass index, current romantic involvement, and dieting. For each one point increase in body mass‐index (BMI), the probability of having a romantic relationship decreased by 6%. Further, involvement in a nonsexual romantic relationship—but not involvement in a sexual romantic relationship—was associated with a significant increase in the likelihood of dieting. Associations between relationship type and dieting did not vary by age, socioeconomic status, or race, but were stronger at higher BMIs. These findings confirm that weight has implications for romantic involvement, which is highly valued by adolescent girls, and that romantic relationships, in turn, are important contexts in which to consider psychological and behavioral accommodation to the physical changes of puberty. 相似文献

This study explores how cohabitation differs for older and younger adults, drawing on data from 966 cohabitors in each of the first 2 waves of the National Survey of Families and Households. Older cohabitors report significantly higher levels of relationship quality and stability than younger cohabitors, although they are less likely to have plans to marry their partners. Few differences were found in the reasons to cohabit, although assessing compatibility is a more important reason for younger cohabitors. Findings suggest that older cohabitors are more likely to view their relationship as an alternative to marriage, whereas younger cohabitors are more likely to view their relationship as a prelude to it. 相似文献
