轨道交通市域线站点周边用地及换乘系统布局方法初探

一、引言 随着天津城市发展空间的拓展,正在逐渐形成“两轴、三带、六板块”的城市空间结构以及以“城市中心-新城-中心镇-一般建制镇”为主线的城镇体系。按照正在编制的《天津市轨道交通线网规划》,天津市的轨道交通线路分为市域线和城区线两个层次,其中规划的市域级轨道线路作为带动市郊新城及中心镇发展的客运交通体系,将凸现其对于引导天津城市空间结构及完善城镇体系布局的重要作用。     

城市轨道交通建设与新城镇发展的互动模式研究——以上海市为例

一、轨道交通建设与新城镇发展互动的两大理论问题 （一）轨道交通建设与新城镇发展的相互关系 轨道交通自诞生以来就表现出对城市空间延伸和对城市体系构建的导向作用．同时在“流量第一”原理的作用下．它又表现出对城市体系中节点城镇的依赖性。这一双重特性为交通区位优势和服务区位优势的结合奠定了基础。只有在交通区位优势与服务区位优势具备了相结合的条件时，以轨道交通建设来引导新城镇发展才会成为可能。轨道交通建设与新城镇枯犀的相百关系体现存以下方面。     

中国城镇化发展30年

改革开放近30年来．我国的城镇化是伴随国家和地区产业结构不断升级、农村劳动力向城市地区不断转移、城市基础设施和社会服务设施日益完善、不断延伸而持续发展的。目前我国已进入了城镇化快速发展阶段．城镇数量和人口均达到了前所未有的规模．城镇作为经济社会的载体在国家和地方经济社会发展中的中心作用得到了进一步的发挥。已具雏形的城镇体系犹如现代化大厦的磐石和骨架．正引领国家现代化事业不断前进。     

探索城市景观形象建设的新思路

改革开放30年来．我国经济社会发生了巨大变化,城市化步伐加快．城市面貌日新月异。21世纪是城市经济的世纪．高速的城市化发展进程．为我国的经济社会持续快速发展提供了基础平台．有效地提高了国民的物质和文化生活质量。另一方面．为适应快速发展的需要,提高城市建设的速度．许多城市简单地采用“模式化”建设方式．忽略了城市的自身特色、地域特点等．照搬照抄国内外其他城市的建筑、风格、特色等,造成了城市建设“千城一面、个性丧失、整体空间景观形象混乱”等问题和遗憾。     

中原城市群：“单中心”向“多中心”的发展对策分析

中原城市群以郑州为中心,包括洛阳、济源、焦作、新乡、开封、许昌、漯河、平顶山、周口等城市。在“中原崛起”的发展战略下,中原城市群得到了较快发展。中原城市群具有优越的发展条件的同时也存在诸多制约因素,优越条件表现在：城镇密度高;区位条件优越;历史文化基础厚;城镇分布集中。制约因素表现在：“核心—边缘”分化明显;“子行政区划”相差悬殊;副中心城市位置较偏。为此,在发展中原城市群的过程中,需要在核心城市郑州之外选择副中心城市,在强化洛阳发展力度的同时,还要强化许昌、漯河,使中原城市群由“单中心”城市体系演变为“多中心”城市体系,形成纵贯南北的“三核城市带”,构建“广域中原城市群”。     

城市文化品牌建设对策研究

在品牌经济时代,品牌就是传播力、生产力、竞争力和发展力。近几年．不少城市提出了建设“文化名城”、“休闲之都”、“生态城市”、“山水城市”、“宜居城市”的发展目标．国内有关机构也先后开展了“全国文明城市”、“最具经济活力城市”、“投资环境金牌城市”等评比活动．打造城市品牌已成为城市发展的动力和重要战略。文化品牌是城市品牌的重要组成部分．     

对我国城市建设盲目症的反思

改革开放30年来．我国已形成了以大城市为中心、中小城市为骨干、小城镇为基础的多层次城镇体系。进入新世纪后．以举办2008年北京奥运会和2010年上海世博会为契机．我国迎来了新一轮城市扩充改造的建设高潮。数据显示．“十五”期间．我国完成的市政公用设施投资总额达到2．03万亿元．比“九五”时期增加了2．85倍：而2007年一年．全国完成的市政建设投资就达到9552亿元．比“九五”5年间累计的市政投资总和还多出2048亿元。     

加快我国生态城市建设的思考

一、我国生态城市建设实践和进展 20世纪80年代．随着我国可持续发展战略的实施．我国开始生态城市研究和建设实践．1984年12月,中国生态学会在上海举行“首届全国城市生态科学研讨会”并成立了“中国生态学会城市生态学专业委员会”。1986年我国江西省宜春市提出建设生态城市的发展目标,     

基于万有引力定律下的城镇体系研究

一、导言随着经济一体化的快速发展,城镇体系、城市发展的理念在不断更新变化。城镇体系作为社会、经济、文化、政治发展的空间载体与投影,城市各地区之间的联系日益密切,相互之间的影响日益增强;与此同时,大批人口涌入城市,寻找工作机会,城市化进程加快,导致城市出现了许多新的问题。要面对这些城市发展过程中出现的"城市病",实现城市快速平衡发展,我们需要将城镇体系作为一个整体来研究,协调其中的关系,共同实现可持续发展。因此,城镇体系研究是     

论城市建设与城市成长

对于绝大多数城市来说．城市建设就是城市改建和扩建的联动过程。即使对于极少数的新建城市．其真正的＂新建＂过程也非常短，很快就会转入新建、改建和扩建的无限循环中。城市作为一个复杂的系统．有其产生、发展的内在规律性．它的成长也像生物有机体一样，需要适当的“阳光”、“水分”、“土壤”等条件．城市建设正是为城市成长创造物质条件的过程。     

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.
