新疆协商民主发展必须建立在正确的价值基础之上,必须体现各民族共同当家作主,必须有利于国家的统一和社会的稳定。因此,新疆协商民主发展必须坚持一体与多元共存的价值基础,坚持人民民主的国家性质和中国共产党的领导,反对“三股势力”的渗透,在尊重多元文化前提下培养少数民族的国家认同意识、公民意识和协商意识。 相似文献

Abstract All 29 operators in the control room of a fire brigade performed test sessions during work and leisure time at 2-h intervals on a day with a 14-h night-shift, a day off and a day with a 10-h morning shift. The test sessions consisted of a visual search choice reaction time test and two Sternberg memory search tests (1 or 5 letters had to be memorized). Furthermore, the operators recorded their oral temperature and their subjective alertness before each test session. The subject also kept a diary of work and sleep times for 14 days. The circadian rhythm of body temperature was hardly changed by a single night-shift. Parallel to the body temperature, the subjective alertness fell significantly during the night-shift reaching a minimum value at 06:00 h. The mean reaction times increased non-significantly at the end of the night-shift and the results of the two Sternberg memory search tests showed no significant trends. The sleep of the operators after the night-shift was on average reduced to 5 hs 34 min. The results of subjective rating of alertness and reaction time test are interpreted as effects of the combined influences of circadian rhythmicity, sleep loss and time on professional task. Most results support the conclusion that a 14-h night-shift without extensive breaks is not acceptable. 相似文献

A strategy for sampling of animal tissues and a statistical approach for analyzing data on body burdens of a parent chemical and its metabolites is presented such that the data may be evaluated in relation to the detection limit(s)of the analytical techniques used and the criterion levels established for acceptable tissue concentrations. 相似文献

Social science literature on aging has assumed without empirical basis that women experience greater continuity in their lives than men and that this is beneficial to women in the process of aging. This research explores the issue of continuity in values over the life course and the relationship of values to a sense of meaning attributed to one's life over the life course. Thirty life history interviews of men and women over the age of sixty-nine were conducted. Differences in values were found between men and women. Men experienced less continuity of values, less continuity in sources of meaning in Life, and more dissatisfaction in the process of life review, but for most men the lack of continuity was not a source of dissatisfaction in old age. 相似文献

AbstractObjective: To examine associations between two body image constructs (body appreciation and body satisfaction) and five health behaviors (diet, physical activity, weight management, tobacco exposure, and alcohol intake) associated with risk for chronic disease, controlling for self-esteem. Participants: Three hundred and forty-four college students enrolled at a large, public university in the southeastern US. Methods: Students completed an online survey composed of measures of body appreciation, body satisfaction, self-esteem, and frequency of engagement in preventive health behaviors. Hierarchical linear regression models were used to assess relationships between constructs. Results: Body appreciation, but not body satisfaction or self-esteem, significantly and positively predicted engagement in diet-, physical activity-, and weight-related health behaviors. No associations were found for substance use outcomes. Conclusions: Results illuminate health risks among college students and provide additional evidence to support the development of holistic preventive interventions that simultaneously address aspects of mental and physical health among college students. 相似文献

ABSTRACT. Participants (124 heterosexual women) completed measures of thin-ideal internalization, discrepancy between perceptions of actual and ideal figure (DISCSELF), perceptions of the discrepancy between estimates of partner's view of actual and ideal female figure (DISCPART), body image, and sexual well-being. We found support for the proposed perception-of-partner pathway in that greater DISCPART was associated with poorer body image, which in turn was associated with poorer sexual well-being. However, we found little support for a link between thin-ideal internalization or DISCSELF and sexual well-being. The results suggest that heterosexual women's beliefs about how their partners view them are important to their sexual well-being. 相似文献

ABSTRACT The prevalence of breast augmentation and breast lift surgery suggests that many women are dissatisfied with their breasts. This study analyzed women's and men's views about breast size and shape among 52,227 heterosexual adults, ages 18–65, who responded to an online survey. Although most women (70%) were dissatisfied with the size or shape of their breasts, most men (56%) were satisfied with their partner's breasts. Younger and thinner women worried that their breasts were too small; older and heavier women were more concerned with breast droopiness. Women who were dissatisfied with their breasts were more likely to report lower body satisfaction and to express concern about wearing a bathing suit in public. Further, dissatisfied women were also less willing to undress in front of their partner and were more likely to conceal their breasts from their partner during sex. These findings suggest that dissatisfaction with breasts is widespread among adult women. 相似文献

Environmental Protection Agency (EPA) ambient air quality guidelines are meant to limit long‐term exposures of toxins to safe levels. Unfortunately, there is little guidance for what constitutes a safe level from a one‐time (or very infrequent) short exposure(s). In the case of mercury, a review of the derivation of the EPA ambient air quality standard shows that it implicitly assumes a tissue burden model. The time dependence of the tissue burden is commonly described in terms of a half‐life, a modeling assumption that presumes that the decline in the tissue burden after a single exposure can be approximately described as an exponential decay. In this article, we use a simple exponential tissue burden model to derive a time‐dependent no observable adverse effect level (NOAEL) for mercury concentrations in air. The model predicts that tissue body burden will asymptotically approach the EPA air quality level for long exposure times, and reach workplace standard levels for exposures of a few hours. The model was used along with data on mercury levels from experimental work done by the Maine Department of Environmental Protection to evaluate the risks from a broken compact fluorescent lamp in a residential setting. Mercury levels approached the NOAEL only when the debris was left in an almost sealed room. Normal common‐sense cleaning measures: removal of debris to an outside area, and ventilation of the room for several minutes, reduced exposures to less than 1% of the NOAEL. 相似文献
