When individuals go on vacation they take on a temporary “vacation identity.” Vacationers use props, behaviors, and interactions with traveling companions to define and bound the experience as separate and different from everyday life. Data are drawn from twenty in‐depth interviews and participant observation with sixty international tourists in China during the summer of 2008. Vacationers' participation in rites and routines and impression management techniques helped them construct a personally meaningful, yet short‐lived identity. The results underscore the influence of others in identity construction and point to the importance of a nonpresent other in creating and presenting identities. 相似文献

A fault tree analysis was used to estimate the number of refrigerant exposures of automotive service technicians and vehicle occupants in the United States. Exposures of service technicians can occur when service equipment or automotive air-conditioning systems leak during servicing. The number of refrigerant exposures of service technicians was estimated to be 135,000 per year. Exposures of vehicle occupants can occur when refrigerant enters passenger compartments due to sudden leaks in air-conditioning systems, leaks following servicing, or leaks caused by collisions. The total number of exposures of vehicle occupants was estimated to be 3,600 per year. The largest number of exposures of vehicle occupants was estimated for leaks caused by collisions, and the second largest number of exposures was estimated for leaks following servicing. Estimates used in the fault tree analysis were based on a survey of automotive air-conditioning service shops, the best available data from the literature, and the engineering judgement of the authors and expert reviewers from the Society of Automotive Engineers Interior Climate Control Standards Committee. Exposure concentrations and durations were estimated and compared with toxicity data for refrigerants currently used in automotive air conditioners. Uncertainty was high for the estimated numbers of exposures, exposure concentrations, and exposure durations. Uncertainty could be reduced in the future by conducting more extensive surveys, measurements of refrigerant concentrations, and exposure monitoring. Nevertheless, the analysis indicated that the risk of exposure of service technicians and vehicle occupants is significant, and it is recommended that no refrigerant that is substantially more toxic than currently available substitutes be accepted for use in vehicle air-conditioning systems, absent a means of mitigating exposure. 相似文献

Abstract A group of 89 male shift-workers, mean age 38 years, was examined for health complaints, subjective experience of their work environment, psychological defence strategies, and immunological factors. They worked in a process industry, controlling a complex chemical process partly by instruments and partly by direct checking of mechanical devices such as valves. Shifts were eight hours long and changed every second week. The main problem areas identified were problems with the management, colleagues and superiors, feelings of being under-valued, time pressure, fear of making mistakes, and lack of influence and communication. The main health complaints were sleep disturbance and gastro-intestinal problems. Shift workers also complained about allergies, breathing difficulties, tension, anxiety and depression. There were no pathological levels of plasma immunoglobulins (Ig) or Ig complements. However, levels did correlate with experience of work-related problems and with measures of defence mechanisms. Up to 25% of the variance in die immunological indicators was explained by a combination of defence mechanism scores and those of perceived health and work problems. This suggests that immunoglobulins may be an indicator of work-related health risks (‘stress’), even if the level of explained variance is too low to use immunoglobulins alone as a ‘marker’. The same variables, and immunoglobulins, also related significantly to perceived health. This may be a particularly important indicator, and when combined with immunology and psychological variables, also as a risk factor for organic disease. 相似文献

This paper compares Models-3/Community Multiscale Air Quality (CMAQ) outputs at multiple resolutions by interpolating from coarse resolution to fine resolution and analyzing the interpolation difference. Spatial variograms provide a convenient way to investigate the spatial character of interpolation differences and, importantly, to distinguish between naive (nearest neighbor) interpolation and bilinear interpolation, which takes a weighted average of four neighboring cells. For example, when the higher resolution is three times the lower, the variogram of the difference between naive interpolation of the lower resolution output and the higher resolution output shows a depression at every third lag. This phenomenon is related to the blocky nature of naive interpolation and demonstrates the inferiority of naive interpolation to bilinear interpolation in a way that pixelwise comparisons cannot. Theoretical investigations show when one can expect to observe this periodic depression in the variogram of interpolation differences. Naive interpolation is in fact used widely in a number of settings; our results suggest that it should be routinely replaced by bilinear interpolation. 相似文献

In the 1970s, as children of Holocaust survivors reached adulthood, many began to excavate, piece together, and re-fashion
their fractured family histories. This movement achieved momentum in the 1980s and 1990s, as the so-called “second generation”
moved into middle age. Drawing from data gleaned from participant observation on a listserv for children of survivors and
from interviews, I argue that those who engage in post-Holocaust genealogy are searching for coherent narratives that place
their own origin in the context of the families into which they were born. By seeking, borrowing from and selectively appropriating
traces of the past, they are using them as raw material in the production of new stories about the past and, by implication,
the present.

Today we recognize that storytelling plays an important role in helping survivors of traumatic episodes such as sexual abuse, military combat, or genocide refashion a sense of self and “work through” their traumatic experiences. But before the Holocaust was named and widely acknowledged and the diagnosis of post‐traumatic stress had emerged, survivors of Hitler's genocidal policies struggled to tell their stories in a world that did not particularly wish to hear them. While most accounts of Holocaust survivors’ postwar experiences focus on themes of redemption, adjustment, and integration, my analysis of interviews with Holocaust survivors suggests during their first two decades living in the United States they were often silenced by individuals they encountered. I use Goffman's analysis of stigma to document how and why this silencing occurred, and with what consequences, providing an account of the interactions survivors had with family members, neighbors and acquaintances, and the strategies of identity management that survivors devised. 相似文献

Little is known about the mental health correlates of problem gambling in low- and-middle-income countries such as South Africa and whether these correlates vary by urbanicity. To address this gap, we examined mental health factors associated with problem gambling among gamblers in Limpopo Province, South Africa disaggregated by rural, peri-urban and urban location. A survey of gambling behaviour and mental health was conducted among 900 gamblers. Overall, 28.3 % were at high risk and 38.1 % were at moderate risk for problem gambling. For the entire sample, hazardous/harmful alcohol use was associated with almost twofold increased chance of being at moderate risk (AOR 1.83; 95 % CI 1.08, 3.11) and almost sevenfold greater odds (AOR 6.93; 95 % CI 4.03–11.93) of being at high risk for problem gambling. Psychological distress was associated with being at high risk for problem gambling only (AOR 1.18; 95 % CI 1.14–1.22). After stratifying by urbanicity, hazardous/harmful alcohol use and psychological distress remained associated with high risk gambling across all locations. We found little knowledge of a free gambling helpline and other gambling services—particularly in less urbanised environments [χ2 (2), 900 = 40.4; p < 0.001]. These findings highlight the need to increase awareness of free helpline services among gamblers and to ensure gambling services include screening and treatment for common mental disorders. 相似文献

This study examines associations between adolescent problem behaviors and adolescent–parent disagreement in ratings of adolescent depression and anxiety symptoms. Adolescent–parent dyads (N?=?463; mean age?=?12.68 years; 48.5% female; 78.2% White and 21.8% non-White) reported on adolescent depression and anxiety using parallel scales from the Youth Self Report (Achenbach et al., J Emot Behav Disord 10:194–203, 2002) and the Child Behavior Checklist (Achenbach and Rescorla, The manual for the ASEBA school-age forms & profiles, University of Vermont, Research Center for Children, Youth, and Families, Burlington, 2001) across four waves. Generalized estimating equations were used to examine the relationship between discrepancy scores and adolescent behavioral outcomes: incidence of adolescent past-year substance use (alcohol use, binge drinking, marijuana use, and nonmedical use of controlled medications), delinquency, self-harm behavior, and aggression. Findings showed that larger adolescent–parent divergence scores of depression were associated with higher odds of marijuana use, non-medical use of controlled medications, alcohol use, binge drinking, in-school delinquency, illegal behavior, self-harm behavior, and clinically significant levels of aggressive behavior. Results further revealed that larger divergence scores on anxiety were associated with higher odds of in-school delinquency, illegal behavior, self-harm behavior, and clinically significant levels of aggressive behavior. Adolescent–parent reporting discrepancy on adolescent’s depression and anxiety symptoms may be indicative of adolescent’s social, emotional, and behavioral problems, and the disagreement may signal further need for assessment of the adolescent. 相似文献

Analysis of data in the form of a set of points irregularly distributed within a region of space usually involves the study of some property of the distribution of inter-event distances. One such function is G, the distribution of the distance from an event to its nearest neighbor. In practice, point processes are commonly observed through a bounded window, thus making edge effects an important component in the estimation of G. Several estimators have been proposed, all dealing with the edge effect problem in different ways. This paper proposes a new alternative for estimating the nearest neighbor distribution and compares it to other estimators. The result is an estimator with relatively small mean squared error for a wide variety of stationary processes. 相似文献

ABSTRACT: Micro-policy instruments are often grouped into labour subsidies and capital subsidies. The purpose of this paper is to investigate the effect on employment of labour and capital subsidies when the wage rate is endogeneous. The problem is studied within a sequential three-stage model, integrating the investment decision, wage-bargaining and the employment decision. The paper demonstrates that labour subsidies may fail, depending on technology and the risk aversion of the workers. 相似文献
