社会人口流动和城市化在中国和全球范围内不断地加强,这些都为中国大多数的农村青年提供了机遇.同时,大量的人口仍然留守农村,无论流动人口输出地有多么偏僻,它们仍继续与日新月异的城市密不可分.正因为如此,农村居民对城市和国家的发展与未来发挥着同等重要的内在作用. 相似文献

One of the most dynamic and fruitful areas of current health‐related research concerns the various roles of the human microbiome in disease. Evidence is accumulating that interactions between substances in the environment and the microbiome can affect risks of disease, in both beneficial and adverse ways. Although most of the research has concerned the roles of diet and certain pharmaceutical agents, there is increasing interest in the possible roles of environmental chemicals. Chemical risk assessment has, to date, not included consideration of the influence of the microbiome. We suggest that failure to consider the possible roles of the microbiome could lead to significant error in risk assessment results. Our purpose in this commentary is to summarize some of the evidence supporting our hypothesis and to urge the risk assessment community to begin considering and influencing how results from microbiome‐related research could be incorporated into chemical risk assessments. An additional emphasis in our commentary concerns the distinct possibility that research on chemical–microbiome interactions will also reduce some of the significant uncertainties that accompany current risk assessments. Of particular interest is evidence suggesting that the microbiome has an influence on variability in disease risk across populations and (of particular interest to chemical risk) in animal and human responses to chemical exposure. The possible explanatory power of the microbiome regarding sources of variability could reduce what might be the most significant source of uncertainty in chemical risk assessment. 相似文献

Many important decisions involve financial risk, and substantial evidence suggests that women tend to be more risk averse
than men. We explore a potential biological basis of risk-taking variation within and between the sexes by studying how the
ratio between the length of the second and fourth fingers (2D:4D) predicts risk-taking. A smaller 2D:4D ratio has been linked
to higher exposure to prenatal testosterone relative to estradiol, with men having lower ratios than women. In financially
motivated decision-making tasks, we find that men and women with smaller 2D:4D ratios chose significantly riskier options.
We further find that the ratio partially explains the variation in risk-taking between the sexes. Moreover, for men and women
at the extremes of the digit-ratio distribution the difference in risk-taking disappears. Thus, the 2D:4D ratio partially
explains variation in financial risk-taking behavior within and between sexes and offers evidence of a biological basis for
risk-taking behavior. 相似文献

Staying strong: gender ideologies among African-American adolescents and the implications for HIV/STI prevention 总被引:1,自引:0,他引:1

This paper explores adolescents' definitions of what it means to be a man and a woman, the psycho-social context surrounding the formation of gender ideologies and their relationship to HIV/STI prevention. Semi-structured, in-depth interviews were conducted with fifty African-American adolescents living in Baltimore, Maryland. Female gender ideologies included economic independence, emotional strength and caretaking. Male gender ideologies emphasized financial responsibility, toughness and sexual prowess. Findings suggest that stronger adherence to male gender ideologies related to toughness and sexual prowess is influenced by male participants' perceived inability to fulfill their primary gender role as economic providers and the importance of gaining approval from male peers in the absence of adult male role models. Stronger adherence to female gender ideologies related to emotional strength and caretaking may be linked to a heightened desire for male intimacy and tolerance of male sexual risk behavior. Implications of the gender ideologies documented and their commonalities are discussed in terms of HIV/STI prevention. 相似文献

This paper examines the role of living arrangements in thequality of life of community-dwelling Chinese elders (aged 65 andover) currently residing in Vancouver and Victoria, BritishColumbia. Data are based on a random sample of 830 persons[response rate = 71.5%], who were interviewed in their homes inthe language of their choice in 1995–96. Three dimensions ofquality of life – satisfaction, well-being and social support –are examined for married men and women [living with spouse alonevs. living intergenerationally] and widowed women [living alonevs. living intergenerationally]. Few differences are found formarried persons, especially women; for widows, living alonesignificantly reduces quality of life in a number of areas.Regression analyses indicate that living arrangements are not asignificant predictor of life satisfaction or well-being formarried men and women. For widows, living arrangements determinewell-being but not life satisfaction.Overall, age, health status, and social support (havingfriends/confidante) are better predictors of quality of life forelderly Chinese Canadians than are living arrangements. Findingshighlight the importance of: empirically distinguishing maritalstatus and living arrangements in studying the quality of life ofelders; not homogenizing Chinese Canadian seniors with regard toliving arrangements; and focussing on Chinese elderly widows wholive alone as a group at risk of low well-being. 相似文献

After mindfulness is defined, a brief history of the research on the topic to date is reviewed. This work essentially falls into three categories: health, business, and education. Considerations of mindlessness as a social issue are then addressed. A brief introduction to the articles in this issue follows. These articles speak to mindfulness as it relates to potential solutions to social problems. 相似文献

We consider some of the ways in which mindfulness theory can provide new solutions to current problems and address potential future problems that may result from changes in demographics and technology. Specific research questions are suggested to see how increasing mindfulness and decreasing mindlessnesscan work to diminish these social problems as they occur specifically in the classroom, the workplace, and the social predicament of getting old. We discuss (a) recasting some of the problems of the elderly into problems of perspective about the elderly, (b) mindful ways of dealing with increased ethnic diversity, (c) differentiating between changing the workplace work and changing the character of the work itself and (d) the advantages and ways of increasingmindfulness in the classroom. 相似文献
