There is a need for greater understanding of how perceptions and objective measures of the physical environment influence physical activity among seniors. The goal of this study was to examine the degree of association between perceived and objective characteristics of the neighborhood environment and the relation of each type of measurement to neighborhood walking in older adults. Data on self-reported frequency of walking in the neighborhood and perceived measures of neighborhood environment from 105 older adults were linked to objective measures assessed by geographic information systems and an audit instrument. Perceived and objective measurements of the built environment exhibited a low degree of agreement (kappas: <.20). After adjustment for education, age, and gender, presence of a mall was positively associated with neighborhood walking in both the objective and perceived models.  相似文献

The definition of family in Australia has been continuously changing over the past four decades. The 21st century has brought with it various images of family, with an increase of awareness to same-sex families; however, the acceptance of such family structures does not appear to be widespread and is often determined by sex. Substantive literature demonstrates differences between men and women in attitudes toward same-sex parenting, with theory suggesting that gender role norms may explain this. Despite large efforts to determine sex differences in attitudes toward same-sex parenting, little research, and even less in Australia, has been done to investigate whether there are differences in reasons behind negative attitudes toward same-sex parenting between men and women. To further this understanding, an Australian sample (N= 790) ranging in age from 18-78 completed a survey regrading attitudes toward same-sex parenting, in addition to relevant demographic information. Participants reported more positive attitudes about parenting by lesbians as compared to parenting by gay men. Reasons behind attitudes toward same-sex parenting also differed between males and females. Results suggested that the impact of socially prescribed gender norms may affect prejudice toward same-sex families. Despite an increase in tolerance for sexual minorities recently, policies that continue to discriminate against same-sex parenting rights demonstrates the importance of continuing to identify potential influences of same-sex family prejudice to reduce the potentially negative impacts associated with the prejudice.  相似文献

Televised role portrayals and interracial interactions, as sources of vicarious experience, contribute to the development of stereotypes, prejudice, and discrimination among children. The first section of this article reviews the amount and nature of racial/ethnic content on television, including limited portrayals of racial/ethnic groups and of interracial/ethnic interaction. The second section focuses on theoretical models that help explain television's role in the development, maintenance, and modification of stereotypes, prejudice, and discrimination. The third section addresses research on the effects of television in altering stereotypes, prejudice, and discrimination, with particular attention given to media intervention programs specifically designed to address these issues (Sesame Street and Different and the Same). This article concludes with a discussion of suggestions for future research.  相似文献

The number of foodborne diseases has increased in all continents, and efforts must be made to control this urgent and expressive public health problem. This article aims to present and discuss situations related to the compliance and noncompliance of food safety practices (FSPs) in light of Bourdieu's social theory. This qualitative study was conducted in commercial restaurants in two cities in São Paulo, Brazil. Participant observation was used in the restaurants, and notes referring to the kitchen workers and their bosses’ work processes were registered in field journals. Thematic type content analysis was used to determine the meaning cores of field journals. It was found that aspects inherent to convenience and haste at work, deficient infrastructure, lack of employees, negative boss examples, exposure to noise, and body pain experienced by workers can contribute to noncompliance of FSPs and consolidate in the habitus and practical sense some dispositions that can increase the risk of foodborne diseases. This study highlights the necessity of creating environments that address food safety, which means being able to perform a service properly.  相似文献

How should companies price products during an inter‐generational transition? High uncertainty in a new product introduction often leads to extreme cases of demand and supply mismatches. Pricing is an effective tool to either prevent or alleviate these problems. We study the optimal pricing decisions in the context of a product transition in which a new‐generation product replaces an old one. We formulate the dynamic pricing problem and derive the optimal prices for both the old and new products. Our analysis sheds light on the pattern of the optimal prices for the two products during the transition and on how product replacement, along with several other dynamics including substitution, external competition, scarcity, and inventory, affect the optimal prices. We also determine the optimal initial inventory for each product and discuss a heuristic method.  相似文献
