Governmental officials, health and safety professionals, early responders, and the public are interested in the perceptions and concerns of people faced with a crisis, especially during and immediately after a disaster strikes. Reliable information can lead to increased individual and community preparedness for upcoming crises. The objective of this research was to evaluate concerns of coastal and central New Jersey residents within the first 100?days of Superstorm Sandy’s landfall. Respondents living in central New Jersey and Jersey shore communities were differentially impacted by the storm, with shore residents having higher evacuation rates (47% vs. 13%), more flood waters in their homes, longer power outages (average 23 vs. 6?days), and longer periods without Internet (29 vs. 6?days). Ratings of concerns varied both among and within categories as a function of location (central vs. coastal New Jersey), stressor level (ranging from 1 to 3 for combinations of power outages, high winds, and flooding), and demographics. Respondents were most concerned about property damage, health, inconveniences, ecological services, and nuclear power plants in that order. Respondents from the shore gave higher ratings to the concerns within each major category, compared to those from central Jersey. Four findings have implications for understanding future risk, recovery, and resiliency: (1) respondents with the highest stressor level (level 3) were more concerned about water damage than others, (2) respondents with flood damage were more concerned about water drainage and mold than others, (3) respondents with the highest stressor levels rated all ecological services higher than others, and (4) shore respondents rated all ecological services higher than central Jersey residents. These data provide information to design future preparedness plans, improve resiliency for future severe weather events, and reduce public health risk. 相似文献

The risks from consuming self‐caught fish are receiving international attention because of high levels of contaminants in some species. The ethnic, income, and educational differences in fishing and fish consumption patterns of 202 anglers fishing along the Clinch River arm of Watts Bar Reservoir adjacent to the US Department of Energy's Oak Ridge Reservation (ORR) or along Poplar Creek within ORR boundaries were analyzed to understand how to design a risk communication strategy. Because of elevated PCB concentrations in striped bass (Morone saxatilis), catfish (Ictalurus spp.), and sauger (Stizostedion canadense) due partly from contaminants released from the ORR in East Tennessee, the Clinch River arm of Watts Bar Reservoir is under a fish consumption advisory, while portions of Poplar Creek are under advisories because of mercury. Most studies find that a high proportion of anglers eat their catch, and people with lower incomes and less education generally eat more self‐caught fish than others fishing in the same region. Calculating fish consumption individually for each person indicated that a considerable number of people ate more fish from the study area than the amount used to calculate risks when developing fish consumption advisories, and people who ate fish more often usually ate larger portions. Unlike previous studies of fish consumption, this study indicated that a smaller proportion of anglers ate their fish, and those that ate the most were the high income anglers for this fishing population, rather than those with lower incomes. This suggests that risk communication strategies must include site‐specific information on the population at risk from fish consumption, and that targeting only low income, low education anglers will miss some people who are most at risk. 相似文献

This paper examines the relationship between sources of family income and household expenditure on private, after‐school education for children in secondary schools in Korea in the context of educational ‘credentialism’, which values evidence of college education highly. Data from a survey of 514 parents of secondary school students are used. Estimated ordinary least squares coefficients indicate that the wife's income, but not the husband's, was positively associated with the amount of spending on children's education at private, after‐school programmes. This finding suggests that some married women with children in Korea seek employment in order to earn the money needed for their children's private, after‐school education. 相似文献

One explanation for the widening of racial earnings gaps among family heads during the 1980s is that black families were increasingly headed by females during that period. This explanation is tested using data on black and white family heads in 1976 and 1985 from the Institute for Research on Poverty's Current Population Survey. Log-earnings equations, corrected for selection bias and for the endogeneity of labor force participation, are estimated for blacks and whites in 1976 and 1985. If the impact of rising female-family headship on labor force participation is ignored, one finds support for the family structure explanation. But support for alternative explanations is also found. There are substantial impacts of within-race gender discrimination and of market racial discrimination. When the endogeneity of family structure is taken into account, further support is found for the view that endowment differences only explain a modest portion of the rising gap in earnings between black and white family heads. 相似文献

This paper proposes a multi-year membership pricing policy for a service business like a gym chain. In the pricing policy, the equivalent membership price per year is relatively low to attract customers, and the multi-year membership fees must be prepaid in full. The prepaid cash provides resources for scale-expansion by opening new stores. We develop a nonlinear mixed integer programming model to formulate the pricing decisions. Numerical experiments reveal that the multi-year membership pricing policy, from a long-term perspective, is substantially better than the business-as-usual pricing policy (1-year membership) in cash balance, profit, and market share. Yet, the performances of the two pricing policies do not differ much from a short-term perspective. These findings indicate that the multi-year pricing policy may be a good strategy, because it initially attracts less attention of competitors; suddenly it emerges and substantially outperforms its competitors in cash balance, profit, and market share. 相似文献

This study developed a procedure to determine the quality priorities of the internet protocol television (IPTV) service. First, a set of key elements of IPTV service quality was developed based on a literature review and a focus group interview. Second, analytic hierarchy process and the Kano model were applied to identify the requirements of experts and customers, respectively. The experts measured the importance and difficulty of management, whereas the customers measured the satisfaction level and importance of each quality element. Third, quality priorities were calculated through the entropy principle and scenario-based analysis. The proposed procedure is illustrated with a case study of a telecommunications company in Korea. 相似文献

The Menu: This paper explores the complex relationship between the marketing of fast and convenience food, and Western constructions and experiences of time in late Modernity, through a polemical analysis of a set of recent British television advertisements for a variety of brands in this sector. A cursory reading of these ads reveals some apparent contradictions in the deployment of time in fast/convenience food marketing: they seem to celebrate both speed (time as “sameness” and “continuity”) and nostalgia (time as “difference” and “discontinuity”). We go beyond a simple understanding of these alternative tropes as indices of competing brand strategies by interpreting their wider relations to the systemic and cultural vicissitudes of contemporary global capital. We conclude that the temporal articulation of fast and convenience foods presented in the ads is not in fact paradoxical, but dialectical. This dialectical relationship is an essential and continuing ideological structure of late Modernity. 相似文献
