一、城市群概念和中部地区城市群一体化发展的内涵(一)城市群的概念一般来说,城市群是在特定的区域范围内,以一个或两个特大城市为核心,聚集相当数量的不同性质、类型和等级规模的城市及小城镇,依托一定的自然环境和交通条件,城市、城镇之间在经济社会方面存在密切的内在联系,共同构成的一个相对完整、相对独立的城镇集合体。在我国,城市带、城市圈、都市群和都市圈统称为城市群。城市群 相似文献

城镇密集区.国外也称作多中心城市区域.是指在一定地域范围内。以多个大中城市为核心.城市之间、城市与区域之间发生着密切联系。城市化水平较高.城镇连续性分布的密集城镇地域。国内有一些相关概念与其近似,如城市群、都市圈、都市连绵带等。但又有细微区别。城镇密度大、城市化水平高、区域整体性强、结构层次多是城镇密集区的基本特征.是社会经济及城镇发展到一定历史阶段的产物。 相似文献

作为中国改革开放后经济最发达、城市化进程最快的地区之一,珠三角城市群经过40年的发展,体系日渐完善,人口规模逐渐壮大,城市之间联系不断加强,城市化水平在国内三大城市群中遥遥领先。但还存在核心城市辐射带动作用发挥不足,城市化水平两极分化严重、与城市规模等级不匹配,产城协调性不高、个别城市严重失调,人口稳定性不强、城镇化质量有待提升等问题。由此,本文提出强化城市群发展思维,推动城市群内创新、产业合理分工,推动产业结构转型升级、产城融合和社会融合,引导人口有序分布,促进珠三角城市群健康发展等对策建议。 相似文献

京津冀协同发展为保定市发展带来了机会,保定市也为此作出积极准备,提出“城市向北”和“一城三星一淀”的重要举措。安国市是保定市辖区内发展较好的县级城市,在“大保定”南侧区域城镇化进程中发挥着重要作用。安国市可以依托产业优势和区位优势逐步发展成为保定市南部的子中心城市,与西部的定州市相融合,成为保定市南部的“双子中心”,在构建“京津石三角形”过程中发挥节点城市作用。安国市的行政区划特征适合以同心圆方式进行城镇化,这需要以构建南北方向和东西方向的主干交通线为前提,并在行政区划内构建辐射状的交通网络,将镇级中心地连接在一起,以“马蹄”形层级城镇体系为基础提升整个区域的城镇化水平。 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 authors reexamine the study of generational differences in adjustment among the children of immigrants by arguing that the country of origin defines and shapes the adaptation process across generations. Using a sample of children in Toronto, the authors demonstrate that generational differences in the mental health of children occur only in families from countries of origin at the lowest levels of economic development. Among those at the lowest levels of economic development, a mental health advantage in the first generation evolves to a disadvantage in the 2.5 generation relative to third or later generational children. Children from backgrounds characterized by higher economic development show no initial or eventual differences from the native born. Using data from the Toronto Study of Intact Families, the authors are able to explain differences among children from low economic development backgrounds specifically in terms of increasing family conflict and decreasing school involvement across generations. 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

The aim of this study was to adapt to the Italian context a very commonly used international instrument to detect problem gambling, the canadian problem gambling index (CPGI), and assess its psychometric properties. Cross-cultural adaptation of CPGI was performed in several steps and the questionnaire was administered as a survey among Italian general population (n = 5,292). Cronbach’s alpha reliability coefficient was 0.87 and can be considered to be highly reliable. Construct validity was assessed first by means of a principal component analysis and then by means of confirmatory factor analysis, showing that only one factor, problem gambling, was extracted from the CPGI questionnaire (an eigenvalues of 4,684 with percentage of variance 52 %). As far as convergent validity is concerned, CPGI was compared with Lie/Bet questionnaire, a two-item screening tool for detecting problem gamblers, and with both depression and stress scales. A short form DSM-IV CIDI questionnaire was used for depression and VRS scale, a rating scale, was used for rapid stress evaluation. A strong convergent validity with these instruments was found and these findings are consistent with past research on problem gambling, where another way to confirm the validity is to determine the extent to which it correlates with other qualities or measures known to be directly related to problem gambling. In sum, despite the lack of a direct comparison with a classic gold-standard such as DSM-IV, the Italian version of CPGI exhibits good psychometric properties and can be used among the Italian general population to identify at-risk problem gamblers. 相似文献
