城市污水处理产业改革的重点探讨与分析

随着我国经济的快速发展,环境问题日益引起人们的普遍关注;随着人民生活水平的提高,对良好居住环境建设的呼声也越来越高.在城市市政公用事业的发展中,污水处理在我国起步较晚,其发展远远滞后于我国的经济发展和城市化进程,目前的污水处理能力既不能满足经济、社会可持续发展的要求,也不能满足城市居民的现状生活需求.加快城市污水处理产业的改革与发展应是当前城市市政公用事业一项重点工作.     

城市经济发展与PM2．5关系探析

基于PM2．5的视角,阐述了PM概念、背景及其在我国当前城市的PM2．5基本现状,并就城市发展与PM2．5关系从城市生活方式、城市生产方式与区域产业结构转型三个不同层面进行探析,认为改变城市生活方式对于缓解城市PM2．5问题作用有限,而根本出路在于区域产业结构转型、升级和生产方式转变,并且以法制形式将环境成本内生化于单一的城市经济绩效考核标准,才真正有可能解决PM2．5的环境问题。

基于多源数据的城市人居环境质量评价研究

在当前我国社会经济转向高质量发展的背景下,城市人居环境研究成为学术界关注的热点。如何准确测量城市人居环境质量,合理评价城市人居环境现状,并采取相应对策,优化城市人居环境,是研究城市人居环境的关键课题。论文在国内外已有研究的基础上,进一步优化数据来源,采用2019年徐州市的房产网站和高德地图开放平台数据,构建以居住与环境、交通与通信、教育与文化、生活与休闲、医疗与健康为准则层的城市人居环境质量评价指标体系,并对徐州市主城区进行综合评价。研究发现：徐州市主城区人居环境呈中间高、四周低的空间格局,形成明显的高质量与低质量集聚区;高质量集聚区包括老城中心、新城中心、铜山副中心、云龙副中心、响山社区;低质量集聚区主要分布在城市周边,可分为老旧小区、安置房小区、工业区配套小区、新开发居住区四种类型;高质量集聚区仍存在居住与环境质量低的短板,是规划提升的主要方向;低质量集聚区的规划提升路径主要包括完善休闲、教育、文化、医疗、交通等公共与生活服务设施。论文创新评价了徐州市人居环境质量特征,促进人居环境评价精细化发展,丰富了中国现有城市对人居环境质量的评估维度和评判方式,能够为城市人居环境建设起到一定理...     

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。     

生态城市建设策略--布鲁塞尔的实践借鉴

城市极大地提升生活质量的同时，也给生态环境带来了巨大的冲击和影响，在生态环境与经济增长两者的均衡方面，作为欧洲最美丽的城市，布鲁塞尔有着较为成功的城市发展模式，其环境管理政策贯穿当地政治、经济、社会、生态及教育等各方面的变革与实践。为人们提供更美好的生活是每个城市发展的最终目标，在实现这一目标的道路上，坚持经济与环境的可持续发展是必由之路，尤其对于仍处于快速城镇化发展中的我国更是如此。笔者从实践方法上，就布鲁塞尔从生态建筑向生态城市演进的过程进行了讨论，以期为我国城市的可持续发展提供参考借鉴。     

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.

Time and aging--mechanisms and meanings

A recent European Molecular Biology Laboratory Conference on Science and Society entitled "Time & Aging--Mechanisms & Meanings" fascinated scientists from different research areas as well as nonscientists. Topics discussed included not only the biological aging process but also the psychological effects of aging and social influences that affect this process.     

Arts and Crafts and Reconstruction

Abstract

This paper examines the role of arts and crafts in reconstructing communities after times of upheaval, their use in creating employment opportunities, and their impact on the nature of South African art history. It looks at craft initiatives during and after the Johannesburg World Summit on Sustainable Development in 2002, and draws parallels with early twentieth-century initiatives, particularly those of Florence Phillips, who founded the Johannesburg Art Gallery in 1910, Emily Hobhouse, who established Boer home industries, and the South African National Union, which promoted the manufacture and use of local products.     

Sexual Compulsivity and Sexual Behaviors Among Gay and Bisexual Men and Lesbian and Bisexual Women

Within the existing body of research, the information pertaining to sexual compulsivity (SC) among women, both homo- and heterosexual, remains rather limited in comparison to men. The aim of this study was to assess the prevalence of SC in a community sample of gay and bisexual men and lesbian and bisexual women and to identify differences in sexual practices based on classification as sexually compulsive within gender. Supporting previous research, the findings indicated that gay and bisexual men were significantly higher in SC when compared to lesbian and bisexual women. Similarly, sexually compulsive gay and bisexual men were more likely to report drug use with sex than their non-sexually compulsive peers, suggesting that “party n' play” may play a larger role for men with SC. In addition, the findings demonstrated empirical support for the proposition that lesbian and bisexual women with symptoms of SC were more likely to engage in specialized sexual behaviors in comparison to their non-sexually compulsive peers. These data suggest that SC manifests differently in gay, lesbian, and bisexual men and women.     

Evening and night work schedules and children's social and emotional well-being

ABSTRACT

An emerging body of evidence shows that parents’ non-standard work schedules have a detrimental effect on children's well-being. However, only a limited number of studies have investigated mediating factors that underpin this association. Likewise, only a few studies have examined the impact of fathers’ non-standard work schedules on children's well-being. Based on data from the Families in Germany Study (FiD), this study aimed to address these research gaps. The sample consists of parents and their children at ages 7–8 and 9–10 (n?=?838 child observations in dual-earner families). The data were collected in the years 2010–2013. Non-standard work hours were defined as working in evenings and or at night (every day, several times a week, or changing as shifts). Children's social and emotional well-being was measured with the Strengths and Difficulties Questionnaire (SDQ). The findings show that both mothers’ and fathers’ evening and night work schedules are linked to an increase in children's externalizing and internalizing behavior and that this association is partially mediated by mothers’ and fathers’ harsh and strict parenting, with a stronger mediation effect for fathers parenting.     

History and the here and now

This paper explores the lesser-known histories and present-day realities of small towns and non-metropolitan areas in the internal provinces of South Africa. It is different inasmuch as it focuses on transformations that have taken place at the local level, and where possible, generalises from these, rather than following the normal route taken by social scientists – at least from 1994, which has been to examine them from the top down. One feature of such changes has been the growth of gated communicates across the length and breadth of South Africa, but there are many more. One reason for their anonymity is that their evolution has been gradual and corpuscular, that they have become unconsciously familiar and are left unexamined. Another is our collective preoccupation with the metropolitan areas rather than the smaller localities where such processes are subterranean and confined. This paper presents very briefly some of the results of the researchers of the Local Histories and Present Realities programme over the past five years, in 19 separate centres. It examines the history and present circumstance of chiefdoms of Ga-Mphahlele and reveals the surprise finding that much of recent and contemporary politics revolve around events 200 years old. An analogous situation has arisen in Venda as well as in Mpumalanga and elsewhere, where a combination of new legislation to revive chiefly powers, and land reclamation legislation have lent a new legitimacy to chiefly powers, and inspired hundreds of phantom – and time-consuming – quests. Another massive development which has gone on around us but whose internal dynamics have never been observed is the rise of game hunting and ranching all over the interior of South Africa. This is a monster subject which is likely to have influence on all of our lives into which our group is now in a position to offer insights. A change of equal proportions is the rise of mining all over the interior Bushveld Igneous Complex – Mokopane is a good example of this and the huge social consequences this has brought in its wake. One final theme which embraces all the communities that we have studied is the local histories of transformation – collectively the most important – since 1994. This is almost entirely hidden to a wider world, including the transformed positions of local Indian residents.     

Thinking and Speech and Protocol Analysis

Some form of verbal report—that is, a research participant' s concurrent or retrospective verbal account of thought processes during problem-solving activities—has been used throughout this century as the database from which psychologists have developed theories of human mentation. Newell and Simon (1972) and Ericsson and Simon (1980, 1993) have provided extensive justification for using one such method, protocol analysis, as a tool for investigating cognition from an information-processing (IP) perspective. Their arguments have characterized protocol analysis as a methodology capable of providing evidence of the ways in which people attend to information stored in short-term memory to solve problems, with the evidence providing them with the grounds from which to generate models of human cognitive processes. A different view of protocol analysis is available from the perspective of cultural-historical activity theory (CHAT) based on the work of Vygotsky (1987), Leont'ev (1981), and others, and its concern with the mediation of human development by culturally and historically grounded signs and tools. Because of its emphasis on culturally channeled development, a CHAT perspective views speech, including the speech that serves as evidence for cognition in psychological research, as a tool that potentially enables changes in consciousness. In this article I outline a CHAT perspective that accounts for protocol analysis along three key dimensions: (a) the relation between thinking and speech from a representational standpoint, (b) the social role of speech in research methodology, and (c) the influence of speech on thinking during data collection. The purpose of this discussion is not to refute the IP perspective on protocol analysis but to illustrate how this method can be viewed through a CHAT lens and to identify alternative assumptions that must be made to use it from a CHAT perspective.
