Defining Cities by Water: Addressing Capital Misallocation in a Race to Conserve Resources

As part of its efforts to promote a sustainable and high-quality development,China has pledged to reduce water consumption and create a water-efficient society.On the basis of identifying the institutional root causes of excessive capital allocation and excessive water consumption in China’s water-intensive industrial sectors,this study elaborates how the national water-efficient cities assessment contributes to optimized capital allocation.Our research shows that national water-efficient cities assessment has motivated local governments to compete for water efficiency.To conserve water,local governments regulated the entry and exit of water-intensive enterprises,discouraged excessive investments in water-intensive sectors,and phased out obsolete water-intensive capacities within their jurisdictions.This approach has resulted in mutually beneficial outcomes,including improved allocation of capital,enhanced water efficiency,and reduced emissions.This paper offers policy recommendations for establishing a water-efficient society throughout the 14^(th) Five-Year Plan(2021-2025)period by presenting empirical evidence on the policy effects of resource efficiency evaluation.

The Cross Sectional Study on the Association between Sexual Awareness and Cognitive Social Capital among High School Students in Ho Chi Minh City, Vietnam

Purpose: We aimed to reveal the association between cognitive social capital and sexual awareness among high school students in Ho Chi Minh City, Vietnam, where adolescent premarital sex is considered to be wide-spreading as consequence of socioeconomic changes, in comparison to our previous study in Hanoi, 2012. Methods: We conducted a questionnaire-based survey and a cross sectional study in late 2014, with 2051 eleventh graders at three high schools in Ho Chi Minh City. Complete data was received from 1935 respondents (94.3%). We assessed basic attributes, sexual knowledge, sexual awareness, sexual experience of peers, cognitive social capital such as a sense of community belonging, and Rosenberg Self-Esteem score. After the independent t-test and multiple logistic regression analyses on sexual awareness were performed assigning trivalent Rosenberg Self-Esteem score, sexual knowledge, and sexual experience of peers as independent variables (model 1), followed by analysis adjusted for cognitive social capital (model 2). This study was approved by Japanese Red Cross Akita College of Nursing (No. 24-003). Results: Of 1935 respondents, 99.9% were 16 or 17 years old and mostly from nuclear families (71.1%). Of all participants, 45.8% in males and 49.4% in females correctly answered on sexual knowledge, 47.6% of males and 28.3% of females accepted premarital sex, 60.0% of male and 65.0% of females knew peers with sexual intercourse experience, and 78.1% of males and 79.1% of females agreed with a sense of community belonging. When multiple logistic regression analyses performed, in model 1, sexual awareness was significantly associated with Rosenberg Self-Esteem score in female. In model 2, above association disappeared but significant association was found between sexual awareness and cognitive social capital in both sexes OR (95% CI), male 1.39 (1.05 - 1.84), female 1.99 (1.49 - 2.65). Discussion: The conservative traditional culture in both Hanoi and Ho Chi Minh City seems to be similar to the concept of cognitive social capital and it is considered to have influenced sexual awareness of high school students in Hanoi and Ho Chi Minh City, Vietnam. Conclusion: Cognitive social capital is significantly associated with sexual awareness among high school students in urban areas of Vietnam.

Childhood Obesity in Primary School Children of Middle and Upper-Middle Income Group in the Capital City of Bangladesh

Background: No published information is available on the status of childhood obesity in Bangladeshi primary school children of urban middle and upper-middle income group. The aim of the study was to explore the proportion of childhood obesity in the primary school children of middle and upper-middle income group in capital city and to gather information on their dietary pattern and physical activity. Methods: One hundred and fifty children (age 9 ± 1 years, height (ht) 118 ± 20 cm, weight (wt) 36 ± 8 kg, wt/ht% 126 ± 24, mean ± SD) were selected purposively from the primary schools of Dhaka city. On the basis of predefined scoring, subjects were classified as underweight, normal, overweight and obese if their weight-for-height values were 120% of median values for Bangladeshi children respectively. Dietary intake and energy expenditure of the study subjects were calculated by standard techniques. Results: The proportion of childhood overweight and obesity was 52% and 20%. The proportion of overweight and obesity was higher (78%) among girls compared to boys (54%). Similarly, height, weight and other anthropometrics indices were significantly (p < 0.05) higher in girls compared to boys. The daily intake of carbohydrate and protein was significantly (p < 0.05) higher among obese group. Total energy balance was significantly correlated with weight-for-height% (r = 0.541, p = 0.0001). Conclusions: A higher proportion of overweight and obesity had been found in girls’ children than their counter parts in this study. Positive energy balance with higher energy intake from carbohydrate and fast/processed food culture habit were found among primary school children of middle and upper-middle income group in the capital city of Bangladesh.

Evolution of the“Golden Royal City”:Analytical study on urban forms of ancient capital cities in Myanmar

The historical cities in Southeast Asia with distinct characteristics are an important part of Asia’s cultural heritage system and the ancient capitals of Myanmar are as an example of these civilizational achievements.Their urban forms through history are essential spatial carriers reflecting the traditional local planning thinking.However,the overall understanding has yet to form due to a lack of systematic research.This study aims to complement it by studying the urban forms of almost all Myanmar’s ancient capitals based on verifiable spatial elements,works of literature,archaeology documents and field survey.The location,boundary and layout elements are analyzed to classify and characterize these urban forms,and their evolution rules are then summarized.Furthermore,the urban planning characteristics are discussed,indicating that the regulated structure and distinctive image gradually formed,accompanied by increasingly mature planning thinking and methods.The study reveals that the urban form and the planning thinking of Myanmar’s ancient capital cities had undergone an evolution with its own characteristics and that the“Golden Royal City”is of unique value in the genealogy of Asian capitals.The findings will contribute to the mutual learning between civilizations and provide a scientific foundation for the heritage conservation.

面向一统的都城规划——再论隋大兴的空间形制建构及其历史意义

隋大兴是在一统全国过程中规划建设的新都城。其营建不仅在于都城空间本身,也包括以都城为核心面向整个疆域的一系列空间建构。本文分析了中国古代“大一统”思想的发展演变以及隋大兴的建设背景,认为隋初围绕大兴城在疆域范围、近畿区域、都城形态三个层面的一系列空间建构是中国古代“大一统”思想与全国一统进程实际需要相结合的空间政治实践,呼应了当时的军事、政治、经济、文化等需求,丰富和发展了“大一统”理念在都城规划中的表达,提高了都城在国家秩序建构和国家认同形成方面的作用,推动了隋唐“大一统”时代的形成和巩固。

范蠡规划越国新都蠡测

都城是国家的政治文化中心,都城规划设计是关系立国立都的大事。春秋末期,吴越两国争霸,结怨相伐,筑城为据。公元前490年,吴王夫差释放了越王勾践,勾践归国后,委托范蠡建设新都。范蠡利用今绍兴府山南麓兴建山阴小城,接着又在小城东侧兴建大城。根据东汉时赵晔撰《吴越春秋·勾践归国外传第八》的描述,对越国新都进行规画复原,揭示规划设计的思想观念与技术方法。

“强省会”战略促进非省会城市消费吗?

立足于虹吸效应和扩散效应,利用2006—2020年中国25个省份的246个非省会城市的面板数据,实证研究“强省会”战略对非省会城市的消费率和人均消费的非线性影响。参数估计结果显示,非省会城市的消费率和人均消费均与省会首位度呈现U型关系,而平均边际效应为负。异质性分析结果显示,省份首位度对非省会城市消费率和人均消费的平均边际影响在无强核和单强核省份均为正,在多强核省份皆为负。非参数估计结果显示,当省份首位度处于适当低的水平时,非省会城市消费率与其呈U型关系,但过高的省份首位度具有虹吸效应,不利于提升非省会城市消费率;而人均消费与其总体上呈U型关系,较高的省份首位度对非省会城市人均消费具有扩散效应。各地要因地制宜实施“强省会”战略,释放消费潜力,从而实现高质量发展。

明清文人笔下的北京记忆--以笔记书名中的北京称谓为中心

明清笔记书名中的北京称谓,成为管窥都城北京书写的一个独特视角。“京师”“帝京”与“旧京”,“长安”“日下”与“春明”,“天府”“宸垣”与“天咫”,“燕都”“燕京”与“燕台”,这四组北京典型称谓,指向不同,蕴意有别,共同凝结成复杂的都城北京意象。这些称谓,既展现出明清时期北京城的多面性与复杂性,也体现出北京自明代以来波谲云诡的都城命运。从明清笔记书名中的北京称谓,可探究作者个人身份与遭际、特定时局与政局等因素对都城北京书写的影响。

城市商业银行设立对资本要素市场整合的影响:促进还是抑制?--基于准自然实验的分析

以城市商业银行的设立为准自然实验,基于1998—2013年中国地级市数据与中国工业企业数据库数据,运用渐进双重差分方法系统考察了地方金融发展对资本要素市场整合的影响。研究表明,城商行的设立显著促进了资本要素市场整合。机制分析表明,城商行的设立通过促进银行业竞争和增加信贷供给推动资本要素市场整合,而政府干预会在一定程度上削弱促进银行业竞争的效应,影响信贷资源流向。对城商行异地扩张和兼并的进一步分析表明,城商行的异地分行设立会促进地区资本要素市场整合,但城商行异地分行数量的扩张又会阻碍资本要素市场整合,而城商行兼并对资本要素市场整合则没有起到显著的促进作用。本文研究结论能为我国优化地方金融体系,促进资本要素市场整合提供理论依据和直观证据。

湖北荆州张大冢战国楚墓出土青铜器的成分与金相研究

利用X射线荧光光谱仪(XRF)、金相显微镜对荆州市纪南镇雨台村张大冢战国墓地出土12件青铜器进行成分与金相分析。结果表明,12件青铜器分别为铅锡青铜、锡铅青铜和锡青铜3种材质,铅锡(或锡铅)青铜器普遍含铅量较高,青铜器多以铸造成形,铜盘均采用热锻加工技术。不同类型及使用功能的器物,其合金成分与金相组织存在明显差异。张大冢墓地作为战国中晚期的楚国下等级贵族家族墓地,出土青铜容器也多为素面薄壁,锈蚀较为严重,但其出土青铜器的合金配比、制作技术及机械性能均展现出战国中晚期楚国工匠已经拥有成熟的青铜合金、铸造以及加工技术,也揭示出当时工匠有意识地在青铜明器与实用器的合金技术上存在区别对待,为全面认识东周时期楚都纪南城青铜冶铸业的发展状况提供科学依据。
