城市供水,作为城市居民饮用水的主要来源,其状况已受到社会各界的普遍关注。当前,城市供水的战略重点,从增加水量转向改善水质。目前,我国大多数的城市供水企业把提高水质的大量工作用于制水厂的净化处理工艺上,往往忽略了供水管网产生的水质污染问题上。因而产生了供水企业出厂水严格按照国家标准执行,而管网水却有不同程度污染的现象,出现浑浊、红水、铁锈、红线虫等,使供水单位声誉受到影响。  相似文献

传统的供水模式采用楼顶水池和水泵联合供水,存在水质容易受到污染、供水不安全、能耗过大等缺点。变频恒压供水系统直接提升供水,因其卫生、安全可靠、设备占地少、性能稳定、能耗低等优点在单位和小区等地方得到了广泛应用。  相似文献

The purpose of this study is to examine the recognition of facial expressions of six emotions as a function of sex and level of education (high school, college, university) of the subjects. Three hundred French-speaking citizens of Quebec had to judge which emotion was expressed in various facial stimuli presented on slides. Results show that overall, the recognition of emotions was very good. However, there were significant and strong differences between emotions and sex and levels of education did not have strong effects on the results.This research was supported by grant EQ-1717 from Fonds FCAC (Gouvernment du Quebec).  相似文献

The idea of a community of learners is based on the premise that learning occurs as people participate in shared endeavors with others, with all playing active but often asymmetrical roles in sociocultural activity. This contrasts with models of learning that are based on one‐sided notions of learning— either that it occurs through transmission of knowledge from experts or acquisition of knowledge by novices, with the learner or the others (respectively) in a passive role. In this paper, I develop the distinction between the community of learners and one‐sided approaches from the perspective of a theory of learning as participation, and use two lines of research to illustrate the transitions in perspective necessary to understand the idea of communities of learners. One line of research examines differing models of teaching and learning employed by caregivers and toddlers from Guatemalan Mayan and middle‐class European‐American families; the other line of research involves a study of how middle‐class parents make a transition from their own schooling background to participate in instruction in a public US elementary school.  相似文献

The purpose of this study was to determine the frequency of sexual abuse and depression among street children who live in a deprived district of Tehran. The researchers used the K-SADS questionnaire and a clinical interview were used to evaluate depression and sexual abuse in 87 street children in Tehran. Eighteen (20.9%) of the children had been sexually abused. Depressed children were 3.2 times more likely to be sexually abused than non-depressed children. Furthermore, 26 girls (86.7%) and 27 boys (48.2%) suffered from depression. The frequency of depression demonstrated a significant association with the father's or breadwinner's history of imprisonment or unemployment. Interventional programs providing education and support should be implemented for street children.  相似文献

中国经济崛起和城市化进程过程中农民工的贡献有目共睹,城市让生活更美好的诱惑使得中国的新老两代农民工从农村流入城市,2008年1月1日的《劳动合同法》和《劳动争议调解仲裁法》让社会看到了改善农民工权利状况的希望,然而新生代农民工的权利保护尤其是作为一名劳动者的权利保护的现状依然不如人意,没有救济的权利不是真正的权利、迟来的正义是非正义,每年岁末对于农民工权益的突击性保障并不能从根本上解决问题,把包括农民工权益保障的社会问题纳入法治框架内、通过探析新生代农民工权利阙如问题及原因进而发现从制度层面进行解决才是解决农民工权益保障问题的根本途径。  相似文献

Human mobility is a complex and multifaceted phenomenon. While labour migration has been widely and deeply investigated – through theoretical and empirical analysis – other forms of mobility have received much less attention. Students' mobility is a peculiar form of temporary movement that can be considered as neither migration nor tourism. It is rapidly growing: in the period 1975–2005 the number of tertiary education students abroad increased fourfold, from 0.61 million to 2.73 million, following the trend of the internationalization of economy and globalization of culture. In 2009 almost 3.7 million tertiary students were enrolled outside their country of origin, an increase of more than 6% from the previous year.

In this paper we analyse the international mobility of university students, using a unique data set built through surveys conducted at the Sapienza University of Rome. The data collected cover a rich array of information on students' characteristics and backgrounds, provenance places, family conditions, individual aspirations, and job preferences. The empirical analysis of those data offers an opportunity for understanding a relevant part of mobility decisions of (prospective) highly qualified workers. The Sapienza University, moreover, is at present the largest university in Europe for number of students and a pole of attraction for both European and non-European students. This allows us to enlarge our analysis at a global level.  相似文献
