Cumulative Trauma Disorder (CTD) is a collection of chronic musculoskeletal disorders caused by frequent, sustained, and repetitive movements, most notably by computer usage at the workplace. A computer based break reminder program (Stop and Stretch) has been developed and installed to prevent CTDs caused by prolonged computer usage at the workplace. We investigated users' opinions to the Stop and Stretch program at their work place. 19 computer users were recruited as the subjects of the study. We conducted a survey after all the subjects used the Stop and Stretch program for one month. Among the nineteen subjects, 52.5% or 10 noticed a difference of symptoms after using the program; 63.3% or 12 thought the program had positive effect on their productivity; 100% or all 19 thought the program was easy to follow; 100% or all 19 thought it was helpful; 94.7% or18 were satisfied with the program; and the same value would recommend the program to others. When grouped into those who had prior experience with using stretch and exercise as part of their work routine15 subjects had no prior experience; and 14 participants within that group were satisfied or very satisfied with the program; 93.3% or 14 would recommend it to co-workers; and over half of those 15 thought the program is easy to use. The study provided insight to the response to using "stretch break software" and provided indicators of satisfaction with the Stop and Stretch program and that the program had sufficient usability and acceptance within a workplace setting which might be applied in other work settings similar to these.  相似文献

Building on Kihlstrom and Mirman (Journal of Economic Theory, 8(3), 361–388, 1974)’s formulation of risk aversion in the case of multidimensional utility functions, we study the effect of risk aversion on optimal behavior in a general consumer’s maximization problem under uncertainty. We completely characterize the relationship between changes in risk aversion and classical demand theory. We show that the effect of risk aversion on optimal behavior depends on the income and substitution effects. Moreover, the effect of risk aversion is determined not by the riskiness of the risky good, but rather the riskiness of the utility gamble associated with each decision.  相似文献

This paper describes the sexual behaviors of 101 male clients with female street prostitutes. An earlier study (Freund, Leonard, & Lee, 1989) was limited to sexual behaviors of street prostitutes themselves. Interviews were given by 62% of the clients approached. The clients were mature men (mean = 39.8 years), long‐term residents of Camden, NJ (mean = 19.2 years), and currently or previously married (78/101). Racial composition was similar to the general population of the area, 65% white, 33% black, 2% Asian. Clients reported a mean of 5.3 years of using prostitution, with 81% having been clients of Camden prostitutes for more than a year. Most were regular (or repeat) clients; 93% monthly or more frequently, and 63% weekly or more frequently. About one‐half (55%) reported sex with the same prostitute or same small group of prostitutes. The primary meeting place was the street (78/101) and 43% of the sexual encounters took place in the clients' cars. Ejaculation into the vagina was most frequently reported (43/101), followed by ejaculation into the mouth (39/101) Reports of condom use were substantial; 72% for vaginal and 33% for oral intercourse (mean = 58% of encounters).  相似文献

Since South Africa’s transition to democracy, civil society has been considered a critical component of new inclusive “democratic” societies, acting to ensure human rights for all. Government and donor agencies require the incorporation of this sector within project documents and programmes. However, is civil society merely a loosely defined term used to satisfy the requirements of project proposals and interests of the state, donors and big business, while not directly addressing the concerns of citizens subjected to macroeconomic risks (e.g. industrial pollution, unemployment and service delivery)? Since the transition, it is mainly established civil society organisations that have become well resourced and who have developed collaborative relationships with the state and industry, which has eroded their accountability to and support from the marginalised communities they claim to serve. Can such organisations then claim to be part of an “authentic” civil society striving for inclusive development? By reviewing contemporary and historical literature on civil society, and through empirical work, this paper argues that there has been a shift in the conception of civil society since the transition, with established forms of support for the grassroots remaining doubtful. Civil society has not effectively engaged with the grassroots to project their concerns about macroeconomic risks, largely due to integration into government/donor institutions. Fragmentation within the grassroots arena has also limited coherent actions against dominant groups. Although civil society can support the grassroots to address their concerns through formal activities, for example, by employing legal strategies, there is no guarantee of success. Connections between an “authentic” civil society and coherent grassroots actions engaging in a combination of strategies (formal and informal) will be required to achieve true democracy.  相似文献

The influence of seasonal change and weather on mood, social activity, weight, food consumption, and sleep length was compared across urban Aboriginals (n = 43), urban non-Aboriginals (n = 49), and remote Aboriginals (n = 39) in Ontario, Canada. Such research is important since climate change may differentially shape the well-being of social groups. Behavioral items—including mood, social activity, weight, sleep, and food consumption—were measured using the Seasonal Pattern Assessment Questionnaire, and associations between these items and meteorological data were examined with bivariate and multivariate approaches. Weather variables had consistent, significant associations with behavior except within the remote Aboriginal group despite living in a more extreme climate. Lifestyle and adaptation may contribute to an increased weather tolerance among remote Aboriginal people, intriguing findings as cultures grapple with the implications of future climate change.  相似文献

Talk and ‘telling’ have assumed prominent roles in preventing HIV and promoting life with the disease at the start of the twenty-first century. Our concern in this paper is to show how social structures and circumstances shape the narrative productions of HIV positive patients whose lives are institutionally managed. We consider what ‘telling’ means when young women with few economic resources are encouraged or mandated to talk about themselves by case managers, researchers, therapists, welfare workers, and clinic staff. We organize our analysis around three such ‘autobiographical occasions’: disclosures to intimate partners prompted by agents of the state; employment opportunities in which women are hired to tell others about living with HIV as peer educators or outreach health workers; and research interviews. We argue that storylines about living with HIV have been laid down by powerful social actors whose illness experiences do not reflect those of many poor patients. These formulations constitute an ‘archive’ which organizes institutional practices and discourses. These matter not only because they provide patients with a language through which to render their actions meaningful, but because they shape the everyday experience of HIV outside the clinic, the welfare office, and the therapy session.

While economic development has been associated with increased participation of females in the labor force, it remains problematic whether sexual equality within the labor force has also increased. This study examines the differentiation of structural variables, specifically economic and demographic variables, on female participation and sexual equality within a specific sector of the labor force: the professions. The units of analysis are primarily European countries with the inclusion of the United States, Canada, Australia and New Zealand. The findings indicate that those economic development factors (female higher education enrollment rate and professional demand) significantly related to the female professional participation rate are distinct from those structural factors (economic growth rate, working age male deficiency) affecting sexual equality within the professional sector.  相似文献

A survey asked 190 pregnant women their opinions on whether a hypothetical other woman would be justified in having an abortion under ten different circumstances, four of which related to abnormalities of the fetus. They were then asked whether they would be justified in having an abortion under these same circumstances. Also assessed were these women's views concerning the justifiability of abortion for a specific group of fetal abnormalities, neural tube defects. Respondents were more likely to view abortion as justifiable for a hypothetical other than for themselves. However, there was no evidence that pregnant women's views about abortion are more conservative than those of the general public. The majority of respondents considered abortion of a defective fetus to be justified, both for themselves and for others. The best predictor of abortion attitudes was respondent's views about the ideal number of children in a completed family.This research was supported by a grant from Maternal and Child Health Research, Bureau of Community Health Services, DHHS.
