Fruit and vegetable consumption of Native Americans was compared with that of non‐Native Americans and determinants of fruit and vegetable intake for both populations were found based upon the Theory of Planned Behavior. A one‐time survey was conducted as part of a larger research project funded by the South Dakota Department of Health. The survey was administered in local grocery stores and supermarkets in six South Dakota communities, including two located on Native American reservations. Of the 1000 distributed surveys, 499 were returned with 230 being usable, resulting in a response rate of 49.9%. Wilcoxon signed‐rank test and two regression models were tested using SAS 9.2 software. Dependent variables were fruit and vegetable intake. Attitudes towards health, fruit and vegetable consumption, perceived difficulty, subjective norm and intention were also measured. Community size, family income, employment status and participation in food assistance programmes [Supplemental Nutrition Assistance Program or Women, Infants, and Children (SNAP or WIC)] were socio‐demographic control variables. Overall, Native American participants consumed more fruit and vegetables at home and had a more positive attitude towards healthy diets than non‐Native American participants. SNAP or WIC participation, family health, exercise, intention to live healthier than parents, buying healthy food, and fruit and vegetable consumption when eating out were positively associated with fruit and vegetable consumption among Native Americans, while participation in the SNAP or WIC programme had a negative influence on consumption among non‐Native American participants. Family health, exercise, buying healthy food, fruit and vegetable when eating out, and intention to buy healthy food were positively associated with fruit and vegetable consumption among the non‐Native American population. Theory of Planned Behavior variables (e.g. attitude towards healthy food) significantly contributed to the model explaining fruit and vegetable consumption. The fact that SNAP and WIC participation had an opposite influence on the two populations warrants further research.  相似文献

The Americans with Disabilities Act (ADA) provides civil rights protections to persons with disabilities, but the debate that preceded passage of the Act was not based on empirical estimates that could be used to measure its performance. This article estimates the extent of wage discrimination against men with disabilities in 1990, providing a reference that can be used to evaluate the impact of the ADA. The results show large productivity-standardized wage differentials between disabled and nondisabled men that are weakly correlated with the strength of prejudice against different impairments. Physical limitations explain part, but not all, of the wage differentials. The results also show that low employment rates are a more serious problem than wage discrimination for workers with disabilities.  相似文献

This study focuses on the risk and return performance of savings and loans that were active acquirers during the early and mid-eighties relative to that of non-acquirers. Acquirers took on more risks than nonacquirers, but were less profitable. Separating acquirers by the health of their acquisitions, acquirers of both healthy and troubled associations or of troubled associations only were more highly leveraged and saw their profitability erode over the post-acquisition period. These results suggest that the problems of integration are compounded when there are multiple acquisitions over a relatively short period of time and when the acquired association is unhealthy.  相似文献

As an increasing number of companies go bankrupt, society grows concerned with the process's efficacy. In contrast to previous research, we find that relatively healthy companies emerge from bankruptcy as evidenced by their operating and equity performance post bankruptcy. While we find a substantial degree of variation in the forecast accuracy of sales, EBIT and net income, we find that forecast errors are not statistically significant and are smaller than had been thought. We provide evidence to support the argument that the economy's health affects operating and equity outcomes post bankruptcy.  相似文献

The central focus of this research is: The growing corporate espionage activities due to fierce competition lead to highly controlling security measures and intensive employee monitoring which bring about distrust in the workplace. The paper examines various research works on trust and distrust. It highlights the conflictful demands managers face. They have to deter espionage activities, but at the same time, build trusting relationships in the workplace. The paper also describes various operations, personnel, physical and technical countermeasuresto combat corporate espionage together with three espionage case examples which illustrate the importance of some of these countermeasures. Various authors' trust and distrust arguments are used to assess the cases. The paper ends with suggestions for future research.  相似文献

This article explores the relationships among influence, autonomy and control in a joint venture setting. It addresses the mechanisms available to joint venture (JV) managers to influence and gain compliance from parent firms. Control categories derived primarily from research on unified structures are explored in a new domain, an international joint venture. the beginning of new theory specific to relationships in joint ventures is developed based on causal maps of managerial perceptions. the results suggest that the use of upward influence to gain autonomy in a joint venture is different and more complex than in unified structures or among independent organizations.  相似文献

This article focuses on township tours outside Cape Town and Johannesburg during the past decade. By examining the subjectivities of guides and tourists, as well as public discourses about townships, I argue that township tours are ethically problematic and ambiguous, but do not go uncontested. Questions about voyeurism and development are negotiated during the tours in a number of ways. First, the morality of witnessing townships – not through the modality of vision, but through participating in contact zones – is asserted. Second, public discourses that valourize the creativity of the poor, and which harness history as a force for reconciliation and development, inform the tours. Third, tour guides attempt to reform charity and to highlight ethical consumption. An ethnographic and discursive analysis leads me to conclude that township tours are part of a larger post-apartheid project of re-imagining and remaking marginalized urban spaces.  相似文献

This study examined the effect of older employees' perceived relative age of their organization's workforce, work group members, and immediate supervisor on human resource practices tailored to older employees and older employees' sense of worth. The 291 participants were aged between 50 and 65 years. Perceived organization relative age was associated with the human resource practices, perceived work-group relative age was related to training and respect, and perceived supervisor relative age was associated with respect and fair treatment. All three relational age variables were related to perceived contribution to the organization. It is important for employers to be aware of the age dissimilarities within their organizations and to take steps to bolster older employees' feeling of being valued organizational members.  相似文献

This paper addresses the impact of tourism on the preservation of ethnic identity with specific reference to the Louisiana Cajuns. Tourism has helped the Cajuns retain a separate identity by reinforcing the differences between Cajuns and outsiders. Cajuns are increasingly relinquishing their traditional culture in favor of standard U.S. values, but they retain a strong sense of identity and ethnic pride. A growing tourist industry was institutionalized at about the same time as the development of ethnic pride, and the two phenomena have profoundly influenced each other. Cajuns have become tourists in their own culture, joining outsiders in seeking and celebrating their brand of “local color” Cajun culture is now enacted on a “tourist stage” for the benefit of locals and their visitors. The tourist stage is an arena for the expression of ethnic differences, and it helps perpetuate an ethnic boundary that might otherwise disappear due to acculturation. Using the Cajuns as a case study, this paper proposes a model for the process of ethnic preservation through tourism.  相似文献
