This paper presents the results and recommendations from a survey regarding arena crisis management. The survey was completed by 150 members of the International Association of Assembly Managers (IAAM). Results indicate a heavy reliance on the two-way radio as a means of communication at the outset, and during, an arena crisis.  相似文献

Following Hochschild's The Managed Heart, which emphasized the problematic features that emotional labour had for women flight attendants, a critical literature emerged which focused on the more enjoyable aspects of emotional labour in service employee experience. This article draws on this literature and analyses emotional labour as a gendered cultural performance but takes issue with the individualizing and pluralistic tenor in the post‐Hochschild discussions. Using a qualitative and quantitative study of nearly 3000 Australian flight attendants, it focuses on organizational and occupational health and safety variables, as well as sexual harass‐ment and passenger abuse — factors barely discussed by Hochschild's critics. The qualitative data indicate that emotional labour is both pleasurable and difficult at different times for the same individual. Gender is still pivotal, as Hochschild suggested, linking emotional labour with sexual harassment. At the same time, the most significant predictors from the quantitative study of whether emotional labour would be costly were organizational. Variables such as whether flight attendants felt valued by the company show that the airline management context is highly influential in the way in which emotional labour is experienced. As a means of understanding the complex relations in this important and eroticized area of service work where flight attendants, airline crews, airline management and passengers have convergent and conflicting interests, the article also deploys a new concept: ‘demanding publics’, to refer to trangressions of the legitimate boundaries of the service worker.  相似文献

In recent years, the emphasis on economic necessity when explaining engagement in alternative consumption practices (i.e. informal and/or second-hand modes of goods acquisition) has been challenged by an agency-oriented reading that views participation to be more a matter of choice, and more recently by a geographically sensitive approach that ascribes agency to affluent populations and economic necessity to deprived populations. To evaluate critically these contrasting explanations, data collected from 120 face-to-face interviews in the city of Leicester are here reported. The finding is that these previous accounts that reduce consumers participation in alternative consumption practices to the mono-causal explanations of either economic necessity or choice obfuscate how both often coexist in people's explanations for participation, albeit in varying ways in different populations. This paper thus displays the need to reconcile the previous reductive either/or explanations through the use of a both/and approach that recognizes and unpacks how both economic necessity and choice are variously entangled in rationales for participation in alternative consumption practices.  相似文献

A method for estimating long-term exposures from short-term measurements is validated using data from a recent EPA study of exposure to fine particles. The method was developed a decade ago but long-term exposure data to validate it did not exist until recently. In this article, exposure data from repeated visits to 37 persons over 1 year (up to 28 measurements per person) are used to test the model. Both fine particle mass and elemental concentrations measured indoors, outdoors, and on the person are examined. To provide the most stringent test of the method, only two single-day distributions are randomly selected for each element to predict the long-term distributions. The precision of the method in estimating the long-term geometric mean and geometric standard deviation appears to be of the order of 10%, with no apparent bias. The precision in estimating the 99 th percentile ranges from 19% to 48%, again without obvious bias. The precision can be improved by selecting a number of pairs of single-day distributions instead of just one pair. Occasionally, the method fails to provide an estimate for the long-term distribution. In that case, a repeat of the random selection procedure can provide an estimate. Although the method assumes a log-normal distribution, most of the distributions tested failed the chi-square test for log-normality. Therefore, the method appears suitable for application to distributions that depart from log-normality.  相似文献

Ongoing publicity about methyl tertiary butyl ether (MTBE) suggests that this chemical is of greater concern than other contaminants commonly found in drinking water. The purpose of this article is to evaluate the available MTBE data in context with other volatile organic compounds (VOCs) that are detected in public drinking water sources in California. We find that of the 28 VOCs with a primary maximum contaminant level (MCL) in California, 21 were found in 50 or more drinking water sources from 1985 to 2002. Over the last 10 years, the most frequently detected VOCs were chloroform, tetrachloroethylene (PCE), and trichloroethylene (TCE), which were found in about 9-15% of all sampled drinking water sources. These same chemicals were found to have the highest mean detected concentrations over the last 5 years, ranging from 13 to 15 microg/L. Many VOCs were also found to routinely exceed state and federal drinking water standards, including benzene and carbon tetrachloride. By comparison, MTBE was found in approximately 1% of sampled drinking water sources for most years, and of those drinking water sources found to contain MTBE from 1998 to 2002, over 90% had detected concentrations below California's primary MCL of 13 microg/L. Relative to the other VOCs evaluated, MTBE has the lowest estimated California cancer potency value, and was found to pose one of the least cancer risks from household exposures to contaminated drinking water. These findings suggest that MTBE poses an insignificant threat to public drinking water supplies and public health in California, particularly when compared to other common drinking water contaminants.  相似文献

BackgroundThe prevalence of overweight and obesity is increasing amongst women of child bearing age. The objective of this study was to investigate the views and attitudes of providers of antenatal care for women who have a body mass index (BMI) of 30 kg/m2 and over.MethodsA qualitative study using focus groups was undertaken within the department of obstetrics and gynaecology at a large teaching hospital in south-eastern Australia. Three focus group discussions were held. One with hospital midwives (n = 10), one with continuity of care midwives (n = 18) and one with obstetricians (n = 5). Data were analysed using Interpretative Phenomenological Analysis (IPA).FindingsSix dominant themes emerged: (1) obesity puts the health of mothers, babies and health professionals at risk; (2) overweight and obesity has become the norm; (3) weighing women and advising about weight gain is out of fashion; (4) weight is a sensitive topic to discuss; (5) there are significant barriers to weight control in pregnancy; and (6) health professionals and women need to deal with maternal obesity. These themes are drawn together to form a model representing current health care issues for these women.ConclusionHealth professionals, who have a high BMI, can find it difficult to discuss obesity during antenatal visits with obese women. Specialist dietary interventions and evidence based guidelines for working with child-bearing women is seen as a public health priority by health care professionals.  相似文献

Past research has consistently documented the positive relationship between a transition to marriage and psychological well-being. In this study, we separate the depressed from the nondepressed to assess whether the benefits marriage has for psychological well-being depend on premarital depression. We also examine whether the effect of marital quality in moderating the psychological consequences of marriage differs for the depressed and the nondepressed. Results indicate that, on average, those who were depressed prior to marrying report larger psychological gains from marriage than those who were not depressed. The role of marital quality in moderating the effect of marriage on psychological well-being is similar for previously depressed and previously nondepressed respondents. These findings call into question the assumption that marriage is always a good choice for all individuals. What appear to be strong average benefits of marriage are actually highly dependent on a range of individual, interpersonal, and structural characteristics.  相似文献
