海合会六国水资源的现状与未来

海合会成员国97％的国土被沙漠覆盖，水资源相当有限，加之目前缺少良好的水资源保护、管理与合理用水的方针、政策与措施，已造成水的供求缺口越来越大，水危机将更加严重。今后，6国必须加强合作，采取有效的水管理、保护与发展措施，改变用水的不良习惯，方能消除水危机的威胁。     

实行最严格的水资源管理制度保障经济社会可持续发展(节选)

(接上期) 四、全面落实最严格的水资源管理制度 实行最严格的水资源管理制度,就是要不断完善并全面贯彻落实水资源管理的各项法律、法规和政策措施,定水资源管理"红线",格执法监督.当前,围绕水资源的配置、节约和保护,确水资源开发利用红线,格实行用水总量控制;明确水功能区限制纳污红线,格控制入河排污总量;明确用水效率控制红线,决遏制用水浪费.要着力做好八个方面的工作.     

积极应对水资源危机逐步建立节水型城市

随着城市化进程的加快,城市规模的扩大,对水的需求量多面广,加之环境污染和不合理的利用,水资源危机日趋严重.因此,全面开展节约用水工作,建立节水型城市势在必行.(1)家庭和企事业单位所用的水表(进水总表)全部改换成数字智能水表(能够倒读数和自动断水).(2)相关管理部门依法制订各行业和系统的用水标准和用水计划,企事业单位依法建立用水报表制度.(3)使用IC卡制度施行公共设施用水的管理.(4)加强供水管道系统的整改.(5)加大地下水资源的管理和保护力度.城市和地区应当依法对所有的水资源进行科学管理.各个用水单位应当依法按照用水计划,科学地、合理地利用水资源.建立健全法律法规,让"计划用水,节约用水"成为一项基本国策,依法管理和利用水资源,逐步建立节水型城市.     

弃而不舍的中庸之道

我国是一个水资源紧缺的国家,水资源人均占有量不足2200立方米,仅为世界平均水平的1/4,全国每年缺水近400亿立方米.在全国670座建制城市中,有400座不同程度的缺水,108座严重缺水,上百个城市不得不被迫限制用水.水危机离我们已经很近:长江源头之一的楚玛尔河流出现断流、东北省的松花江断航、河北白洋淀干涸、北京密云水库的水降至水位底线、敦煌因缺水生态恶化……     

水文化在建设节水型高校中的应用

中国水文化历史源远流长，但把水文化作为一种独立的文化形态提出来加以研究的时间并不长。在水资源分布不均的我国，水资源短缺对社会发展和经济增长的制约日益严重。中国人均水资源总量约为2220m^3，仅为世界人均水资源量的1／3。预计到21世纪中叶，我国将进入联合国评价的用水紧张国家的行列。面对水危机，为了充分利用现有的水资源，节约用水势在必行。节约用水也成为了我国当今水文化中的一项重要内容。

从污水回用发展历史看城市第二水源的前景

水资源缺乏是21世纪人类面临的最为严峻的资源问题之一.联合国早在1977年2月就向全世界发出警告--"水危机不久将成为一个重要的全球性危机".如今,全世界面临水资源危机,产生水危机的原因主要包括用水量急剧增加、水污染、水资源开发不合理、浪费严重等几个方面.将处理过的工业、城市污水回收利用作为城市第二水源,使污水资源化,以解决水资源的短缺问题,是缓解城市用水紧张以及控制水污染的一条有效途径.我国是一个水资源匮乏的国家,人均水资源占有量仅为0.22万～0.27万立方米,是世界平均水平的1/4,列世界第88位.随着经济发展和城市化进程的加快,城市缺水问题日益突出,相当一部分城市水资源短缺.据统计,全国669个城市中,400多个城市常年供水不足,其中110个城市严重缺水.     

七大流域综合规划获批将实行最严水资源管理制度

来自水利部的消息,继2012年底国务院批复长江、辽河流域综合规划后,国务院日前批复了黄河、淮河、海河、珠江、松花江、太湖流域综合规划.至此,七大流域综合规划(修编)全部得到国务院批复. 七大流域综合规划分别研究制定了2020年、2030年完善流域防洪减灾、水资源综合利用、水资源与水生态环境保护、流域综合管理四大体系的目标和任务.此外,规划突出实行最严格的水资源管理制度,确定了流域用水总量控制、用水效率控制、水功能区限制纳污红线规划意见.     

如何摆脱水危机阴影

<正>1水危机的警钟已经敲响早在上个世纪的70年代,联合国专家已指出:继石油之后,人类下一个危机就是水危机。2002年8月在约翰内斯堡举行的可持续发展世界首脑会议上,全体与会代表一致通过将水危机列为未来10年人类面临的最严重挑战之一。水危机的表现在于水资源的短缺、污染和与     

水危机触目惊心 粗放利用未得到根本扭转

随着经济社会的快速发展,人类对水的浪费、污染、掠夺,使得诸多地区缺水、缺安全之水已越来越成为经济社会发展的瓶颈,并引发一系列生态与环境的恶化和生态链的断裂等问题。江河断流,湖库淤积;地下水超采,湿地退化;围湖造地,侵占河道;水污染频发——在水资源短缺和水污染严重的暗流涌动下,我们身边潜藏着怎样的水危机?水危机困扰大江南北罕见的秋冬春连旱,不久前还在考验着素有"鱼米之乡"美誉的长江中下游地区。持续干旱给我国第二大淡水湖洞庭湖带来了严重影响,洞庭湖水位5月

Accuracy of the judgment of facial expression of emotions as a function of sex and level of education

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).

Developing understanding of the idea of communities of learners

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.     

The frequency of sexual abuse and depression in a sample of street children of one of deprived districts of Tehran

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.     

劳动法视域下新生代农民工权利缺失问题

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。

Mobility of students and attractiveness of universities. The case of Sapienza University of Rome

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.
