This study’s purpose was to develop a temporal and cultural definition of volunteering in China. Using a comparative mixed-methods approach, N1 = 218 Chinese students in Hong Kong were surveyed about their perceptions of volunteering. These quantitative data were compared cross-culturally with a sample of adults in the United States who used the same instrument called Who is a Volunteer? Subsequently, N2 = 40 of these same students voluntarily participated in a series of focus groups, to further explore more in-depth their opinions about volunteering. The main quantitative results revealed that at the extreme ends of the volunteer scale, both the U.S. and Chinese samples could readily distinguish what volunteering was or was not. The more nuanced empirical differences on the scale (24% of the 21 items) were explained either by unique cultural differences, or the longer and more prominent history that volunteering has had in North America versus China. Main qualitative findings revealed additional between-group cultural differences exemplified by (1) a more family-centric and collectivist Chinese culture versus a more individualistic American culture, (2) a role blurring about volunteer activities versus paid work activities, and (3) that both organizational and cultural context must be seriously considered when defining volunteerism. This study adds to the growing definitional literature on this transformational concept and represents the largest comparative empirical investigation on this subject from East Asia.  相似文献

The main objective of this study is to evaluate the impact of school furniture and work surface lighting on the body posture of two public Middle School students from Paraíba (Brazil). The target population included 8th grade groups involving 31 students. Brazilian standards for lighting levels, the CEBRACE standards for furniture measurements and the Postural Assessment Software (SAPO) for the postural misalignment assay were adopted for the measurements comparison. The statistic analysis includes analyses of parametric and non-parametric correlations. The results show that the students' most affected parts of the body were the spine, the regions of the knees and head and neck and about 90% of the students presented postural misalignment. The lighting levels were usually found below 300 lux, below recommended levels. Such results indicate the need of investments in more suitable school furniture and structural reforms aimed at improving the lighting in the classrooms, which could fulfill the students' profile and reduce their complaints.  相似文献

A number of studies to better understand the complex physiological mechanism involved in regulating body weight have been conducted. More specifically, the hormones related to appetite, leptin and ghrelin, and their association to obesity have been a focus of investigation. Circadian patterns of these hormones are a new target of research. The behaviour of these hormones in individuals subject to atypical working times such as shiftwork remains unclear. Shiftwork is characterized by changes in biological rhythms and cumulative circadian phase changes, being associated with high rates of obesity and metabolic syndrome. Truck drivers, who work irregular shifts, frequently present a high prevalence of obesity, which might be associated with work-related factors and/or lifestyle. In this context, the aim of this paper was to discuss the relationship of body mass index, appetite-related hormones and sleep characteristics in truck drivers who work irregular shifts compared with day workers.  相似文献

This paper presents a protocol for work distress assessment. Work distress is defined as a merge between nonergonomic related aspects, in tasks or environment, and adversely conditions perceived for a worker, in a certain work situation. This frame requires an approach that can treat individuals and organizational factors in the same way, at the same time. For this, we elaborate a psycho-ergonomics method, associating concepts and practices from cognitive-behavioral techniques and work ergonomic analysis, which we named CEWAT - Cognitive-Behavioral Work Analysis Technique. This paper presents CEWAT's foundations and structure, in steps. An application to a complex and dangerous system illustrates its benefits in the ergonomics action.  相似文献

This article presents an ethnographic study of politics of waiting in a post‐Soviet context. While activation has been explored in sociological and anthropological literature as a neo‐liberal governmental technology and its application in post‐socialist context has also been compellingly documented, waiting as a political artefact has only recently been receiving increased scholarly attention. Drawing on ethnographic fieldwork at a state‐run unemployment office in Riga, this article shows how, alongside activation, state welfare policies also produce passivity and waiting. Engaging with the small but developing field of sociological literature on the politics of waiting, I argue that, rather than interpreting it as a clash between ‘neo‐liberal’ and ‘Soviet’ regimes, we should understand the double‐move of activation and imposition of waiting as a key mechanism of neo‐liberal biopolitics. This article thus extends the existing theorizations of the temporal politics of neo‐liberalism.  相似文献

Genetic differences (polymorphisms) among members of a population are thought to influence susceptibility to various environmental exposures. In practice, however, this information is rarely incorporated into quantitative risk assessment and risk management. We describe an analytic framework for predicting the risk reduction and value-of-information (VOI) resulting from specific risk management applications of genetic biomarkers, and we apply the framework to the example of occupational chronic beryllium disease (CBD), an immune-mediated pulmonary granulomatous disease. One described Human Leukocyte Antigen gene variant, HLA-DP beta 1*0201, contains a substitution of glutamate for lysine at position 69 that appears to have high sensitivity (approximately 94%) but low specificity (approximately 70%) with respect to CBD among individuals occupationally exposed to respirable beryllium. The expected postintervention CBD prevalence rates for using the genetic variant (1) as a required job placement screen, (2) as a medical screen for semiannual in place of annual lymphocyte proliferation testing, or (3) as a voluntary job placement screen are 0.08%, 0.8%, and 0.6%, respectively, in a hypothetical cohort with 1% baseline CBD prevalence. VOI analysis is used to examine the reduction in total social cost, calculated as the net value of disease reduction and financial expenditures, expected for proposed CBD intervention programs based on the genetic susceptibility test. For the example cohort, the expected net VOI per beryllium worker for genetically based testing and intervention is $13,000, $1,800, and $5,100, respectively, based on a health valuation of $1.45 million per CBD case avoided. VOI results for alternative CBD evaluations are also presented. Despite large parameter uncertainty, probabilistic analysis predicts generally positive utility for each of the three evaluated programs when avoidance of a CBD case is valued at $1 million or higher. Although the utility of a proposed risk management program may be evaluated solely in terms of risk reduction and financial costs, decisions about genetic testing and program implementation must also consider serious social, legal, and ethical factors.  相似文献

Siting Noxious Facilities: A Test of the Facility Siting Credo   总被引:2,自引:0,他引:2  
Over the past decade it has become increasingly difficult to site noxious facilities, despite the fact that there is a growing need to do so. To address this problem, a set of guidelines for a fairer, wiser, and more workable siting process—the Facility Siting Credo—was developed during a National Facility Siting Workshop in 1990. This paper presents an empirical test of these guidelines. A questionnaire based on the Credo was completed by stakeholders in 29 waste facility siting cases, both successful and unsuccessful, across the United States and Canada. Using an independent determination of outcome (success), a preliminary ranking of the importance of various Credo principles was obtained. The data reveal that establishing trust between the developer and host community is an important factor in facilitating the siting process. The siting process is most likely to be successful when the community perceives the facility design to be appropriate and to satisfy its needs. Public participation also is seen to be an important process variable, particularly if it encourages a view that the facility best meets community needs. Moreover, a siting process where communities volunteer to host facilities is an approach that holds promise for meeting many of these key success criteria.  相似文献

Traditional risk assessments, including those involving the United States Department of Energy (USDOE), are often criticized for producing useless or noncredible management responses because they did not meaningfully involve the public. The first step to involve the public is to identify appropriate active participants (stakeholders). This study was done to understand the processes used to identify stakeholders to serve on advisory boards established at the two largest remediation sites in the United States: the Hanford Nuclear Reservation in Washington state and the Savannah River Site in South Carolina. The Hanford stakeholder identification process produced an interest-based board whereas the Savannah River Site strategy produced population-based representation. The basic goals of the stakeholder advisory groups were similar. However, different processes were used to identify the participants for the groups in part because of distinctly different social and cultural conditions in the areas affected by the operations of the two facilities, and in part because of the different level of trust of the USDOE and their contractors at Hanford compared with Savannah River. The discussion analyzes their different needs and potential for successful citizen participation.  相似文献
