珠三角城市群人口、经济与环境协调性研究

人口、经济与环境耦合协调是高质量发展的重要体现.以珠三角城市群为研究对象,探究2005-2018年人口、经济和环境发展格局及耦合协调趋势,为推动城市群高质量发展提供借鉴与方向.'结果表明:①珠三角城市群发达城市之间的人口、经济与环境方面的协调发展差异有所减小,但与欠发达城市间的差异不断扩大;②城市群人口、经济与环境耦合协调性有所增强,但近年来耦合性降低,协调性增速放缓,部分城市出现人口、经济与环境无法相互促进,反而出现了相互制约;③城市群人口、经济和环境耦合协调的空间分布呈现核心—边缘格局.提升珠三角城市群发展质量应从人口、经济与环境耦合协调性入手,因地制宜采取针对性提升措施.     

决定北美洲大中城市竞争力的耦合协调度——基于北美洲131个大中城市数据的分析

采用统计分析、耦合协调度分析、相对指数分析、OLS回归分析等方法,建立城市竞争力的指标体系,构建包括科技创新、金融服务、产业体系、营商环境、营商成本、人力资源、基础设施、生活环境等要素的耦合协调度。研究结果表明:经济竞争力排名越高的城市,其耦合协调度也越高;经济竞争力排名越低的城市,其耦合协调度也越低,经济竞争力与耦合协调度存在高度相关性。耦合协调度处于优质协调和良好协调的城市主要集中于美国和加拿大等国家的金融科技创新城市和区域性金融科技创新城市;耦合协调度较低的城市主要集中在墨西哥等不发达国家的城市。影响北美洲城市竞争力的驱动因素不同,各地应因地制宜,抓住城市发展的关键驱动因素,补短板、强弱项,协调城市经济发展,促进城市经济竞争力的提高。     

工业化、环境承载力与绿色基础设施的协调关系 ——以天津市为例

工业化在提高经济发展水平的同时,对环境承载力产生了较大影响.环境承载力水平也制约着工业化的发展质量.绿色基础设施作为应对环境问题的重要工具,其与环境承载力、工业化的协调发展对三者的发展水平有积极作用.笔者以天津市为例,在对其工业化发展水平、环境承载力发展水平与绿色基础设施发展水平进行组合评价的基础上,运用耦合协调度模型分析三者之间的协调关系.结果表明,天津市的工业化、环境承载力与绿色基础设施的协调发展程度总体处于失调状态,提升空间较大.由此,笔者提出对策建议:一是扩大城市绿色基础设施建设规模,二是探索工业化、环境承载力与绿色基础设施的协调发展机制,三是加强工业化、环境承载力与绿色基础设施协调关系评估与管理.     

中国投资、消费与出口协调发展评价 ——基于1978年～2019年的数据分析

投资、消费与出口是拉动经济增长的"三驾马车".中国经济发展进入新常态,保持三者之间的相互协调,是促进中国经济发展模式转变的重要动力.笔者以1978年～2019年的数据为样本,在分析投资、消费与出口现状的基础上,通过构建耦合协调度模型,对中国投资、消费与出口的协调发展程度进行评价.结果表明,三者之间的协调发展程度相对较低,需要调整经济的需求结构,促进中国经济三大需求活动的协调发展.     

中国城市休闲化耦合协调发展比较研究——以5个计划单列市为例

城市休闲化是后工业化时代城市发展的一种形态,其耦合协调发展一定程度上反映出城市休闲化的总体水平和整体质量。文章通过构建城市休闲化评价指标体系和耦合协调度模型,对2004-2013年中国5个计划单列市城市休闲化的耦合协调发展进行比较研究。研究发现:(1)城市休闲化综合指数大致呈持续上升态势,且城市间差距保持在一定水平。(2)从子系统功效来看,经济与产业发展对城市休闲化的发展功效最大,而且变化趋势相对平缓;(3)耦合协调度比较显示,深圳基本处于领先水平,然而城市间差距并未逐步拉大。

石化园区产城融合策略探讨——以福建省泉港产城融合示范区为例

产城融合是"十三五"及今后一个时期我国城镇化进程中的一项重要任务.笔者以国家发改委公布的第一批58个产城融合示范区之一——福建省泉港区为例,探讨石化产业园区与城市的融合发展策略.由于石化产业的特殊性,石化园区的产城失调不仅体现在与中心城市之间,更严重的是与新城之间.石化园区与新城之间的产城失调,主要反映在两个方面:一是石化产业与新城不协调,主要是新城发展滞后;二是新城发展与城市功能不协调,主要是城市功能提升缓慢.石化新城产城融合的主要任务是加快城市发展步伐,尽快提升城市功能.为此,必须走新型城镇化道路,同步推进三个方面的融合发展:产业融合发展是关键,目标是构建以工业、 商贸和旅游为主体的现代产业体系;社会融合发展是核心,重在构建以现代市民为主体的城市社会;空间融合发展是基础,努力构建生产、 生活和生态相协调的空间格局.     

基于同城化视角的人口空间动态与区域经济发展耦合关联机理研究

人口空间动态与区域经济发展的耦合关系是同城化区域间共同面对的重要课题。本文在解构人口空间动态维度主体的基础上,将人口空间动态的诉求机制与动因机理架构于更低交易费用的利益诉求之上,解析人口空间动态的模式选择,深入探讨人口空间动态与区域经济发展的耦合关联性。在此基础上,提出引导人口流动与合理分布的策略。研究成果将有助于更好地理解同城化态势下人口空间演变的动因机理,为同城区域的经济发展、城市规划、文化交融等方面的科学设计提供重要参考。     

珠三角9市文化与旅游产业耦合发展研究

文化产业和旅游产业融合发展是推动经济转型的重要手段,粤港澳大湾区是我国建设世界级城市群、参与全球竞争的空间载体.以粤港澳大湾区珠三角9市为研究对象,构建了文化产业和旅游产业的评价指标体系,采用熵值法计算体系中各指标的权重,得出珠三角9市2019年文化产业和旅游产业的评价值,引入耦合协调度模型,测算各城市文旅产业的耦合协调度.结果 发现,珠三角9市中,文化产业和旅游产业发展最好的都是广州市;各城市旅游产业的发展水平极不平衡;文旅产业的协调程度整体较为良好,大多数城市处于协调状态.

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.

This study looked for to lift information regarding laundries inserted in industries of animal products origin, to understand the activities developed in the section and to structure a Manual of Planning and Technical Information for laundries to industries of animal products origin, with the intention of subsidizing the planning, structuring and control of this work place, because norms or regulations that supervise don't exist or aid their managers and workers as for the operation of this work place.     

The impact of generation and country of origin on the mental health of children of immigrants

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.     

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。

An Assessment of the Psychometric Properties of Italian Version of CPGI

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.
