Research on the Path of Improving the Efficiency of Urban Community Governance from the Perspective of Collaborative Governance:A Case Study of Daqing City,China

Under the background of“co-construction,co-governance,and sharing,”the role of the grassroots level is becoming increasingly important.In the past,the governance body was single with blocked information,and the inefficient governance mode required gradual transformation.In order to achieve collaborative governance and break through the obstacles in grassroots governance,the key lies in how to play the role of the community,coordinate the relationship between citizens and the community,and allow the community to better play the role of grassroots governance.Under the guidance of the concept of collaborative governance and combined with relevant data,this paper discusses the problems and current situation of community governance in Daqing City,China,explores the path to improve the efficiency of urban community governance,and puts forward relevant constructive suggestions to better realize the role of community in grassroots governance.

Understandings of Urban Sustainability in China:a Bibliometric Analysis Using Chinese Literatures

Cities hold a critical responsibility for achieving the Sustainable Development Goals(SDGs)due to their high population density,extensive resource consumption,and significant economic contributions.To examine the present state of understandings regarding urban sustainability(SDG 11:Sustainable Cities and Communities)within Chinese research communities,this study collected 15950 papers from 1994 to 2022 on the 12 indicators of SDG 11,from the China National Knowledge Infrastructure(CNKI),a hub of Chinese academic papers,that directly relate to policymaking.Significant research topics on SDG 11 were identified for each indicator using bibliometrics analysis approaches.The high-frequency keywords and clusters of keywords over the last three decades reveal that existing studies primarily concentrated on the physical aspects,such as transportation and environment,while there is a lack of consideration of societal aspects.This indicates a limited and biased understanding of the urban sustainability within the Chinese academic community.Hence,it is crucial to prioritize the societal aspects in order to develop a research agenda that further advances urban sustainability.

A Cradle-to-Cradle Novel Approach for Wastewater Management in Sustainable Urban Communities

Water, a valuable resource to human lives, is being abused and driven to scarcity. This scarcity is leading some countries and areas to face difficulty in accessing drinking water. As the UN recently stated “by 2050 water shortages and harder access will be reached by around 2/3rd of the world total population” [1], thus, there is a high need to treat and reuse wastewater for domestic purposes, which will lead to less reliance on fresh water as an initial water source. Greywater—defined as the water produced in domestic houses including sinks and bathroom showers, and excluding any blackwater mix which is collected from toilets—is a type of wastewater. Greywater accounts for up to 75% of the daily water produced [2] while it has fewer contaminants when compared to blackwater. This makes greywater a focal point for treatment, and reusing to conserve fresh water and approach net zero water concept. Even though the definition of greywater is the same globally, its criteria can differ from one country to another, from one building to another, or even from the same person’s usage along the day. Accordingly, several treatment methods evolved over years aiming at treating the produced greywater for reuse mainly in irrigation and toilet flushing. The objective of this paper is to demonstrate a novel net zero wastewater approach applying cradle-to-cradle concept for urban communities;while also proposing a sustainable greywater treatment technique that is environmentally friendly, cost-effective and socially acceptable.

Prospects and limitations of soil amendment and irrigation techniques for the water-saving public urban greenery and ephemeral weed management in the sandy soils of the United Arab Emirates

Public urban greenery greatly contributes to the residential and tourist value of cities in the Gulf Region,but due to the hyper-arid climatic conditions,the cost of irrigation and plant maintenance is very high.Existing strategies to reduce the monetary and ecological costs involve the cultivation of native xerophytic plantations,and/or the use of soil improvers to increase water-and nutrient-holding capacity of the sandy soils.Various soil improvers based on mineral,organic,or synthetic materials have entered the United Arab Emirates(UAE)market in recent years,but there is considerable uncertainty about how they should best be used in combination with ornamental plant stands involving xerophytic native plants.The present study investigated the effect of soil amendment and deep pipe irrigation on perennial ornamental plant stands involving native plants(Tephrosia appolinea(Gel.)Link in combination with Aerva javanica(Burm.f.)Juss.ex Schult.)and native-exotic plants(T.appolinea in combination with Ruelia simplex C.Wright)either or not topsoil and subsoil amendment with bentonite and hydrophobic sand under the irrigation water supply of less than 50%of reference evapotranspiration(ET0).After one year of cultivation,T.appolinea and A.javanica(native vs.native)produced high biomass and exhibited high water use efficiency(WUE)as compared with T.appolinea and R.simplex(native vs.exotic)combination given that no significant differences were found under the soil amendment treatments.All stands thrived under irrigation water supply far below what is usually supplied to exotic ornamental stands in public parks of the Al Ain City,the UAE.However,subsoil amendment in combination with deep pipe irrigation reduced the occurrence of weeds and increased the overall plant rooting depth.Our results suggest that subsoil amendment and irrigation up to 60-80 cm depth can potentially control ephemeral weed infestation,which is a great challenge in various plant production systems of the Gulf Region.The results of the present study suggest that the impact of soil amendment on the WUE of exotic plants is marginal and might not be economically justified.Replacing exotic with native ornamental plant species seems to have a far greater water-saving potential than the amendment of the soil,while weeds can be suppressed in the absence of topsoil moisture.

Diversity Analysis on the Plant Communities of Urban Park Green Space in Wuhan

In order to systematically study the diversity of plant communities in park green space,78 plant communities of 10 representative parks in Wuhan City were investigated.The total 449 species belonging to 275 genera and 112 families were found in this investigation.The communities were divided into 35 dominant-species,13 life-forms and 6 vegetation-forms.The community structures and the composition of dominant species were also studied.The results showed that the shortages of the low diversity,high proportion of exotic species and simple community structures appeared in plant community of park green space in Wuhan City.It is proposed that species,especially native ones,should be abundant to keep a high level species diversity.At the same time,more simulated native communities should be utilized to build the natural,multi-layers,bright local vegetation characteristics landscape of urban parks.

Research on the Harmonious Development of New Rural Communities under the Perspective of Balancing Urban and Rural Areas

On the basis of offering a definition of New Rural Communities (NRCs), the paper analyzes the values of New Rural Communities and argues that the construction of NRCs is able to contribute to the enhancement of the comprehensive agricultural production capability as well as the development of social productivity. Meanwhile the incomes of the rural residents can be boosted, which denotes the realization of a harmonious society where the achievements of China's reform and development are shared by each citizen. Moreover, the construction of NRCs facilitates the economization of land use and thus improves the overall living standard of the residents, while helping to cut the administrative cost and promote democracy at the primary level. This paper also points out various problems arising during the construction of NRCS in China: blindly following suit in accordance with the modes of the urban communities; lack of funds, which leads to the absence of the supporting mechanisms of NRCs; vague positioning and the ensuing shortage of impetus for continued development. Finally, the paper raises the corresponding measures and suggestions: first, based on reality, make overall planning and scientific arrangement; second, the government should play the dominant role while respecting the principal position of the rural residents and introducing the market mechanism; third, increase science and technology input and attach equal importance to economic and social benefits; fourth, broaden fund-raising channels while completing the supervision mechanism.

Significant Differences in Elderly Health between Urban and Rural Communities: A Literature Review

This study aimed to examine measures pertaining to elderly health in urban versus rural settings, and to identify differences in the health of elderly people living in urban and rural communities through a literature review. An electronic literature search was performed using PubMed for English articles published in peer-reviewed journals up to August 2018, with the following search terms: “urban”, “rural”, “comparison of community”, “elderly health”, and “comparison of community health”. A total of 35 articles were extracted for a critical full-text review, and six articles that met the inclusion criteria were subjected to analysis. Measures related to elderly health in urban and rural communities were classified into the following three categories: functional abilities, health, and health perception. Five of the six articles described functional abilities (e.g., social function) and health (e.g., mental health, depression) as categories with significant differences in elderly health between urban and rural communities. The results suggest that elderly health measures related to social function and mental health or depression are more important outcome measures of effective person-centered integrated community care systems from the perspective of community characteristics. As there were only a few articles reporting on elderly health according to differences in environment between urban and rural communities, further investigation is globally warranted.

Bacterial Communities Associated with An Occurrence of Colored Water in An Urban Drinking Water Distribution System

This study aimed to investigate bacterial community in an urban drinking water distribution system （DWDS） during an occurrence of colored water. Variation in the bacterial community diversity and structure was observed among the different waters, with the predominance of Proteobacteria. While Verrucomicrobia was also a major phylum group in colored water. Limnobacter was the major genus group in colored water, but Undibacterium predominated in normal tap water. The coexistence of Limnobacter as well as Sediminibacterium and Aquobocterium might contribute to the formation of colored water.

CHINA’S URBAN RESIDENTIAL COMMUNITY IN THE COURSE OF TRANSFER OF SOCIAL PATTERN

Even though the study of urban sociology in China is just a beginning,it doesn't mean that urban social problems in China are new or simple. As a Very sensitive field, urban prudential community has not been deeply analysed owing to various reasons. This article tries to start with the background of China's social development and analyse the pattern, essence and evolution fortion of China's urban residenhal community which is in the course of transfer of social Pattern. This article first analyzes the functiond mechanism of seven main elements affecting Chinese urban residential community in the course of transfer of social pattern. Some of the elements come into being under the social economic background, with Chinese characteristics, and have a profound influence on urban residential community. Based on that, the author then respectively infers the evolution of four ban patterns of urban prudential communities in China now. Finally, it puts forward the basic principles of urban community development in the current transfer period in China, and with a development eyesight, it makes a summary of the general characteristics of the Chinese urban residential community in the future.

The Strategy of Outdoor Space Micro-Renewal under the Goal of Communities for All Ages: A Case Study of Xingchaibeiyuan Community in Nanchang City

With the rapid development of the city,the old city has gradually lost its former glory,and the old community accounts for a large proportion in the city,and is located in the core area of the city. At present,there are some problems in the old community,such as high degree of aging,poor quality of living space,and lack of outdoor space. The old community transformation is mainly in the way of ' guided reconstruction',it has completely destroyed the original historical environment and the spirit of the place. Therefore,taking Xingchaibeiyuan Community in Nanchang City as an example,we deeply explore the strategy of micro-renewal of community outdoor space,so as to provide a reference for the renewal of outdoor space in this kind of old residential area.

Understanding Everyday Homes of Urban Communities： The Case of Local Streets （Hawari） of Old Cairo

This paper aims at investigating architectural and urban heritage from the sociocultural point of view, which stands on the human asset of traditional sites such as the hawari of old Cairo. It analyzes the social practice of everyday life in one of the oldest Cairene hawari, Haret al Darb al Asfar. The focus is on architectural and spatial organization of outdoor and indoor spaces that coordinate the spatial practices of local community. A daily monitoring of people＇s activities and interviews was conducted in an investigation of how local people perceive their built environment between the house＇s interior and the outdoor shared space. It emerges that people construct their own field of private spheres according to complex patterns of daily activities that are not in line with the classical segregation between private and public in Islamic cities. This paper reports that the harah is basically a construct of social spheres that are organized spatially by the flexible development of individual buildings over time and in response to changes in individuals＇ needs and capabilities. In order to achieve sustainability in old urban quarters, the paper concludes, the focus should be directed towards the local organization of activities and a comprehensive upgrading of deteriorating buildings to match the changing needs of current population.

Study of Problems in the Development of Non-profit Organizations in Urban Communities

With the continuous advancement of construction of urban communities and the continuous development of the needs of community residents in China,non-profit organizations in various urban communities have developed rapidly and have increasingly played an important role in social and economic life. At present,the development of non-profit organizations in urban communities is still faced with many problems,such as difficulty in raising funds,lack of incentives that results in low enthusiasm for volunteering and low participation of community residents,etc. It is urgent and practical significance to study,analyze and solve the problems faced by non-profit organizations in urban communities. That article focuses on the analysis and discussion of the problems facing the development of non-profit organizations in urban communities,and proposes countermeasures to solve the problems.

Community Based Management of Severe Acute Malnutrition: The MSF Experience from an Urban Slum Setting in Bangladesh

Background: Until recently, the experience on implementing community based management of acute malnutrition (CMAM) among children has been largely based in African settings. While the government in Bangladesh is yet to scale up CMAM approach, there is still paucity of knowledge on the experience of CMAM within the complex milieu of an urban slum context. In Kamrangirchar slum, Dhaka, Bangladesh, this paper describes a CMAM programme performance and outcomes run by Médecins Sans Frontières (MSF)/Doctors without Borders, in light to performance indicators set by MSF and the Sphere minimum standards. Methods: This was a descriptive retrospective study using routinely collected programme data of children admitted with severe acute malnutrition between May 2010 and November 2011. Kamrangirchar is an urban slum of a large migrant population in Dhaka, Bangladesh. Results: There was a total of 640 new admissions, of whom 333 (52%) were males. The median age was 18 months (Inter-quartile range (IQR) 12 - 41). 599 children had a reported nutritional outcome at discharge from ambulatory therapeutic feeding centre (ATFC), this included: cure rate of 69% with an average length of stay of 68.8 (SD ± 46.0) days and average weight gain of 3.8 g/kg/day (SD ± 2.7). The lost-to-follow-up rate was 18% and 5% reported to the programme that they will leave the slum and go back to their villages. These performance indicators did not meet the threshold level indicators set by MSF and Sphere standards. Conclusions: Our experience highlights the need for developing more adapted and contextualised indicators for assessing the performance of CMAM programmes in settings such as urban slums. Community engagement in the process of developing relevant standards is crucial. Nutrition humanitarian actors have a vital role to collaborate with local authorities to contextualize and refine these standards.

Community Needs Assessment in Relation to Urban Heat Effects: A Study in Greater Kuala Lumpur, Malaysia

Urban areas usually experience higher temperatures compared with their rural surroundings; this is characterized as urban heat islands （UHIs）, which are the result of environmental overheating due to anthropic activities. Urban areas,which are characterised by massive construction that reduce local vegetation coverage, are subject to the absorption of a large amount of solar radiation,which is only partially released into the atmosphere by radiation in the thermal infrared.

Strategies for Dealing with Gang Activity in Urban Communities

As disturbing as youth and gun violence is, it is not hard to reduce the mortality rate because it is preventable. The information provided in this research will help to get policies waiting to be reviewed by legislators, and any new proposal that reaches the appropriate legislative chamber, reviewed without obstacles and will help to prevent youth violence. Upon completion of this research, the study shows that rates of youth violence have decreased based on programs implemented at the state government level with a stronger juvenile justice system holding offenders accountable to ensure public safety and reduce youth violence and victimization. The study shows that community and school involvement with law enforcement and government agencies are some of the strategies needed to help reduce gun violence and rebuild communities.

Community walking space is the most used space in residents’daily life,such as commuting and walking,and is also the most basic type of space for outdoor activities.The microclimatic environment of walking space not only affects the health status of residents,but also determines the service effi ciency of outdoor public space.Based on actual measurement and simulation of microclimatic environment,the status quo of walkability of microclimatic environments in six typical communities is evaluated by quantitative methods,and general problems and optimization suggestions are put forward,in order to provide new ideas for future community environment transformation.

Impacts of Rapid Urbanization to Traditional Living Environment and Community Linkage in Historic Old Quarters of Vietnam： A Case Study on Gia Hoi Area in Hue City, Central Vietnam

Though with slight ups and downs, Vietnamese economies have been flourishing for recent decades. Just like other remaining historical districts in Asia, those of Vietnam have been going through rapid urbanization and transformation. The rapid urbanization impacts on traditional living environment. This paper examines the impacts of rapid urbanization to traditional living environment and community linkage, illustrating a case study of the Gia Hoi area of the historic old district in the city of Hue in Central Vietnam. To identify the impacts, a comparative analysis is conducted between neighbors along a main street which were more impacted by urbanization and those along a small alley which were less impacted. Through the analysis of field and questionnaire surveys, it found out that socioeconomic conditions, in particular, community linkage of households along main street and small ally varied significantly. It argues that in historical district, social capital is not well-spread, but rather concentrated along small allies, and small allies play an important role for sustainable community.
