Although some regulatory frameworks for the occupational health and safety of nanotechnology workers have been developed, worker safety and health issues in these laboratory environments have received less attention than many other areas of nanotechnology regulation. In addition, workers in nanotechnology labs are likely to face unknown risks and hazards because few of the guidelines and rules for worker safety are mandatory. In this article, we provide an overview of the current health and safety guidelines for nanotechnology laboratory workers by exploring guidelines from different organizations, including the Department of Energy Nanoscale Science Research Centers (DOE-NSRC), Massachusetts Institute of Technology (MIT), the National Institutes of Health (NIH), the National Institute for Occupational Safety and Health (NIOSH), the Occupational Safety and Health Administration (OSHA), Texas A&M University (TAMU), and University of Massachusetts-Lowell (UML). After discussing these current guidelines, we apply an ethical framework to each set of guidelines to explore any gaps that might exist in them. By conducting this gap analysis, we are able to highlight some of the weaknesses that might be important for future policy development in this area. We conclude by outlining how future guidelines might address some of these gaps, specifically the issue of workers’ participation in the process of establishing safety measures and the development and enforcement of more unified (and mandatory) guidelines.  相似文献

We document an apparently widespread violation of dominance in the horse‐racing betting market in the UK, and use the systematic variation in the incidence of this violation to estimate the consumption value of gambling. Betting‐shop gamblers in the UK face a tax on gambling of 10%, but have the choice of paying the tax either at the time of wager or on any return on a successful bet. It can be shown, however, that the latter act is strictly dominated by another action in which tax is paid on the wager. Despite this, more than 18% of bets appear to be placed by gamblers who choose to pay tax on the return. We explore the hypothesis that this apparent violation of rationality may be explained by a component of utility which represents the consumption value of gambling, which in turn varies with the amount wagered. We then estimate this component from a dataset consisting of a record of 25,000 individual bets using probit analysis of the tax decision. Copyright © 1999 John Wiley & Sons, Ltd.  相似文献

Past research has established that personal religiosity is positively associated with a sense of meaning in life. However, it has largely overlooked how religious others influence one's own life meaning. Given that a marital partner may be the most influential other in a person's everyday life, this study aims to examine how the religiosity of one's spouse is associated with the sense of meaning in life of the self, regardless of the religiosity of the self. Moreover, this study assesses whether this association differs by gender. Analysis of data from the 2006 Portraits of American Life Study reveals that spousal religiosity is positively associated with the partner's meaning in life, net of the partner's own religious commitment. However, these observed patterns do not vary by gender. Overall, these observations highlight the importance of social contexts in which others’ religious attributes are related to one's own meaning in life.  相似文献

This study examines whether belief in supernatural evil is associated with mental health. In addition, it assesses how secure attachment to God moderates this association and how gender conditions the moderating effect of secure attachment to God. Among a variety of mental health outcomes, this study focuses on general mental health problems as well as anxiety-related disorders (e.g., general anxiety, social anxiety, and paranoia). Using data from the 2010 Baylor Religion Survey (N = 1,627), the analyses reveal that belief in supernatural evil is positively associated with general anxiety and paranoia. In addition, secure attachment to God buffers the positive associations between belief in supernatural evil and social anxiety and paranoia. Yet, when general mental health problems and general anxiety serve as the outcome measures, secure attachment to God attenuates the positive associations of belief in supernatural evil with mental health only for women, but not men. These results underscore the ways that religious beliefs have both positive and negative implications for mental health. Furthermore, they highlight the importance of gender in the complex relationships between religious beliefs and mental health.  相似文献

Adolescent females, particularly urban and low-income youth of color, are at particular risk for HIV infection. This article uses an empowerment perspective to consider the degree to which intrapersonal and interpersonal power dynamics in heterosexual relations have an impact on condom use among high-risk youth. Participants in this study were 333 African American and European American urban youth, ages 14–19 years, who were heterosexually active. Measures focused on interpersonal and intrapersonal factors thought to be associated with condom use. This model was most useful in predicting condom use among women and least useful in predicting condom use among male participants. Implications for empowerment theory and future research are discussed.  相似文献

The purpose of this research is to examine how the COVID-19 pandemic has impacted the luxury goods industry. The authors hypothesize that pandemic threats drive consumers toward luxury consumption to increase their perceptions of control. The article reports results of three experimental studies conducted in the United States. In Study 1, after participants read an article about COVID-19, they respond favorably to an advertisement for a luxury brand. The comparative control participants read an article about a tofu dish and respond less favorably to the luxury advertisement. Study 2 provides further evidence that perceived control acts as a mediator, while ruling out alternative explanations. Study 3 indicates that threat evokes luxury preferences only when advertisements for both luxury and nonluxury products use abstract messages, as opposed to concrete messages. The findings provide practical insights showing that the most effective advertising strategy for luxury brand managers is to use abstract rather than concrete messages for targeting consumers who feel highly threatened by COVID-19.  相似文献

Variety-seeking research has examined antecedents in terms of contextual factors and individual differences. However, it does not consider the interaction of individual difference factors such as regulatory focus (promotion vs. prevention) and regulatory mode (locomotion vs. assessment) to predict variety-seeking. Drawing on regulatory fit theory, this study introduces a new kind of regulatory fit based on the interaction between regulatory focus and mode (i.e., regulatory focus–mode fit), thereby extending previous work examining fit based on either regulatory focus or regulatory mode in isolation. Results from five studies, including field data from 10,547 music app consumers (text analysis), two preregistered studies, and two online experiments, show that regulatory focus–mode fit (vs. non-fit) decreases variety-seeking. Engagement and attitude certainty serially mediate regulatory focus–mode fit effects. Findings provide implications for consumer segmentation and message framing.  相似文献

The present study investigated the relative contribution of style of peer attachment (secure, anxious, avoidant) and quality of attachment to parents on behavior problems in Korean adolescents. In addition, we examined the role of paternal and maternal attachment separately as a potential moderator in the relationship between style of peer attachment and internalizing and externalizing behavior problems. Middle school students (245 males, 209 females) completed the Korean version of the Adolescent Friendship Attachment Scale, Inventory of Parental and Peer Attachment-Revised, and Youth Self-Report. Attachment to peers and parents as predictors of behavior problems were tested via hierarchical multiple regression analyses. Results revealed that anxious peer attachment remained the strongest predictor of behavior problems among adolescents (internalizing behavior problems β?=?.18, p?<?.01; externalizing behavior problems β?=?.21, p? <?.001), indicating the relative importance of peer relationship compared to attachment to parents. Paternal attachment significantly moderated the relationship between avoidant peer attachment and externalizing behavior problems (β?=?.15, p?<?.05), even when the main effect of avoidant peer attachment on externalizing behavior problems was not significant. Results highlight the role of both attachments to peers and parents on adolescents’ psychological adjustment.  相似文献

Parental perception of a child’s weight is important in determining parenting and feeding styles, which relate to childhood obesity. Evidence suggests this perception can vary by ethnicity. The purpose of this review was to explore Asian parents’ child weight perception and examine factors related to Asian parents’ child weight misperception. A systematic literature review was conducted on eight studies between 2000 and 2016 through the databases of CINAHL, Cochrane Reviews, PsycINFO, Medline, and PubMed. Searching key words were Asians, Asian-Americans, weight perception, and parents. The review revealed that all eight studies identified child weight misperception, but with highly varying results (ranging from 29.7 to 89.2%). Factors that influenced the accuracy of a parent’s child weight perception included maternal BMI, parental gender and age, child’s BMI, child’s own weight perception, child’s gender and age, and child’s birth order and birth weight. Misperception about their children’s weight is prevalent among Asian parents. Anthropometric measurement of a child, rather than a parent’s reporting of a child’s weight, should be used to educate Asian parents regarding childhood obesity. Health care professionals should be aware of misperceptions when developing and providing a culturally appropriate intervention to address overweight/obesity among Asian children, which might include improving weight perception.  相似文献
