Spatial restructuring and the logic of industrial land redevelopment in urban China: Ⅳ. A case study of jointly redevelopment by multi-actors

Within the inventory era, urban shrinkage characterized by economic decline and space decay has been widely witnessed in China. The modes and trajectories of urban redevelopment have thus become areas of major concern for both policymakers and scholars. Taking the multi-actor participation nature of redevelopment, this paper stemming from the game-theoretical approach demonstrates in empirical terms on two major fronts. First, the redevelopment of industrial land without the transfer of land use right is shown to be deadlocked by the incapacitation of the original land-user and unlocked with the participation of the new developer. Second, the preference of the original land-user to maximize its interests by operating by itself rather than continue to cooperate with the new developer is observed in the post-redevelopment stage. Therein, the entrepreneurial local government acts only as a “mediator” between the two market entities and tends not to directly intervene in their cooperation. Thus that, it is the reasonable distribution of potential benefits or the pricing of different rights in the land property right bundle rather than their definition that matters more for land redevelopment. Because the delineation of land property rights has never been a problem in a mature land market, particularly for stock industrial land.

Provably Secure APK Redevelopment Authorization Scheme in the Standard Model

The secure issues of APK are very important in Android applications.In order to solve potential secure problems and copyrights issues in redevelopment of APK files,in this paper we propose a new APK redevelopment mechanism(APK-SAN).By exploring sanitizable signature technology,APK-SAN allows the original developer to authorize specified modifier who can redevelop the designated source code of APK files.Our scheme does not require interactions between the developer and modifiers.It can reduce the communication overhead and computational overhead for developers.Especially,the signature of redeveloped APK files is valid and maintains the copyrights.The proposed APK-SAN signature can effectively protect the security of the redeveloped APK files and copyrights of the developer and modifier.

Mode and Mechanism of Urban Land Redevelopment

On the basis of summarizing and appraising the mode and mechanism of land redevelopment in urban regeneration in China’s transitional period,the relationship between land redevelopment system and urban regeneration is analyzed from the perspective of land system,and then the cooperative mechanism of urban regeneration and land redevelopment is recommended for promoting the development of urban regeneration.

Dilemma for the Redevelopment of Village and Town Construction Land, Formation Mechanism and Policy Suggestions

Under the context of economy new normal and rapid urbanization, the shift of economic growth, structural adjustment pains as well as pre-stimulus digestion comes coincidentally. The boundary red line of urban growth, the red line of the number of basic farms and the ecology red line makes the local to conserve land. Land stock for village and town construction is a huge amount of potential resources. Redevelopment of land for village and town construction provides ensured land security for the smooth progress of urbanization. Combining village and town construction land use characteristics and making in-depth analysis of the difficulties in the redevelopment of village and town construction and its inner mechanism, policies and suggestions were proposed for the redevelopment of village and town construction land in terms of land property, land price, market allocation, planning, surveillance and so on, so as to provide valuable reference for the smooth redevelopment of village and town construction land, and the system design of villages and towns.

Application of CAD redevelopment in process design of stepping-mode laser blanking

To design a stepping-mode laser blanking process,in this study,CAD software was redeveloped based on VBA and a computer interface was established in the process design system. The program employs the modularization method to perform functions including one-key initialization of the process planning environment,creation and deletion of blanking steps,automatic identification of belt coordinates,recognition of the number of blanking steps in each domain,and the output and import of process data. The difficult problem of recognizing CAD block references with the same name in the automatic acquisition of belt coordinates is solved using the selection sets method,which greatly improves the efficiency of the process design,while also guaranteeing rapid development of the flexible data mold in stepping-mode laser blanking.

Evaluation of urban redevelopment impact on non-motorized traffic

As an important component of city evolution, urban land redevelopment has an impact on transportation system. The current traffic impact analysis （TIA） is lack of a comprehensive component for non-motorized transportation under redevelopment. For a better guidance of land redevelopment and non-motorized transportation planning, it is necessary to evaluate the negative impact of redevelopment on non-motorized traffic in the TIA. In this paper, an evaluation framework for the impact analysis is built up. We organized the pro- cedures and components of impact evaluation, and proposed the corresponding qualitative and quantitative evaluation indicators for non-motorized traffic under redevelopment. Level of service （LOS） and its criterion are employed for external impact evaluation, and level of safety, convenience, independence, and comfort which are four aspects of quality of service （QOS） are proposed to analyze the internal impact. The framework is applied to a redevelopment study in Shanghai, China. The case study results indicate that the rede- velopment from a residential area to a mixed commercial area has a significant impact on non-motorized traffic. The potential negative impact from both external and internal traffic can be minimized by reasonable improvements in the internal land use design.

A structural project： Redevelopment of the historic center of Wuhu

Restoration and redevelopment are difficult when traces of things that require preservation have been minimized. Such operations are even more complex whenever a portion of an ancient city is involved. This essay describes the redevelopment project of the historic center of Wuhu through the different themes raised during the drafting of the project： from the cultural opportunity of a wide reconstruction work, to the definition of the main design strategies, and the question of memory and identity. The results show that the field of intervention in this project is broader than that of most restoration projects, that is, an evolving city center, which is impossible to consider with traditional restoration parameters or with pure conservation. The only possibility of interven- tion is on the city structure, which allows the city to develop itself continuously within a welt- defined system of rules.

Reconstructing Social Capital to Promote Urban Redevelopment:A Case of Lianjiao Area in the Pearl River Delta Region

Guangdong Province started the so-called"three olds redevelopment"in 2009,aiming to advance industrial upgrading.Existing literature points out that appropriate distribution of land rent differential among the stakeholders like urban governments,village collectives,and developers is the most important determinant.Employing the theory of urban regime,the paper focuses on the redevelopment process of the Lianjiao Area in the Pearl River Delta region to reveal how the three entities(government,rural community,and developers)interact.It has been found that the local urban government is the main driver which facilitates the positive accumulation of social capital through the supply of redevelopment policy and fi nancial support.Through the reconstruction of trust of villagers and developers,the government gains the rights to coordinate the redevelopment.As the actual landholder,rural villages represent the profi ts of villagers in bargaining with the other two parties.The improvement in infrastructure and the formulation of detailed redevelopment plans increase the land rent differential,encouraging developers’participation in the redevelopment.The three entities form a negotiation-based development alliance and fi nally lead to successful redevelopment.

Brownfield Redevelopment Based on Theories of Urban Regeneration and Landscape Urbanism:A Case Study on Changchun Tractor Factory

Urban development and construction has led to a series of problems,such as the deficiency of land resources,difficulty in old city renovation,and backward landscape construction,etc.Brownfield refers to the abandoned and polluted lands of industrial,commercial,or other uses,whose redevelopment can not only effectively stimulate the intensive utilization of urban lands and the growth of urban economy,but also improve the quality of the urban ecological environment.Considering that the research on brownfield redevelopment methodologies in China is still at its initial stage,the application of the theories of urban regeneration and landscape urbanism in brownfield redevelopment will be conducive to solving various urban problems and promoting brownfield land use values.This paper,based on an analysis on the theoretical connotations of urban regeneration and landscape urbanism and their infl uences on brownfi eld redevelopment,argues that the urban regeneration theory can serve as the"framework"while the landscape urbanism theory as"skeleton"of brownfi eld development,both of which can integrally form the"organic body of brownfi eld redevelopment."It further puts forward fi ve primary principles for brownfi eld redevelopment which are elaborated through a case study on Changchun Tractor Factory.

Measuring residents’ anxiety under urban redevelopment in China: An investigation of demographic variables

Residents’concerns and feelings play pivotal roles in smoothly promoting urban redevelopment.Anxiety,as an intuitive feeling toward uncertainties,generally exists among residents who are confronted with redevelopment,and this feeling has gradually attracted scholars’attention.However,relatively few studies have focused on the multidimensional view of this concept and its influencing factors.Drawing upon a large-scale questionnaire survey conducted in 13 pilot areas in China,this study refines and verifies five prominent dimensions of anxiety,namely,housing conditions,monetary compensation,public services,life adaptation,and public participation level,through factor analysis and one-sample/-test.The finding contributes to achieving a complete understanding of anxiety,and the scales developed for measuring these dimensions lay the foundation for further empirical studies on anxiety.The individual and collective effects of age,job,and region variables on anxiety dimensions are demonstrated via independent-sample/-test and analysis of variance,which clarifies the formation process of anxiety and highlights the importance of these contextual variables.Tailored strategies for policymaking and engineering management,including establishing reasonable compensation standards,providing equal public services,and delivering highquality housing,are proposed to relieve residents5 anxiety.These strategies are expected to consider further the sensitive group,such as the elderly,farmers,and casual workers.

Theory and Countermeasures on Stakeholder Governance in Redevelopment of Urban Villages

While urban villages are combinations of interests of different stakeholders,the redevelopment of urban villages is the benefit rearrangement among these stakeholders,whose target is to create values for all stakeholders and the society effectively.The principle of urban village redevelopment is to meet the multiple requirements of all stakeholders and balance the benefits of the dynamic environment.This paper discusses the utilization of theory of stakeholder governance amid urban village redevelopment.It proposes a "four in one" benefit coordination mechanism from the view of city planning.Some valuable policy suggestions on that are also put forward at last.

Institutional Change and Urban Redevelopment Process:A Case Study of Changshoujie,Shanghai

Through investigating the institutional change and urban development in Shanghai since 1978,this research identifi es that the gradual economic reforms have generated dynamic forces for urban development. As an example,this paper examines Changshoujie in detail to uncover its physical changes and to explore how the actors' roles and interests interplay as well as how the transitional institutions of property rights and urban planning have impacted the shaping of urban space. 117 projects constructed since 1978 are classifi ed into six development modes according to the characteristics of land users and developers. Although there is a time lag,the path depending on institutional change has a direct impact on urban development and the consequent spatial structure.

Clogging mechanisms and preventive measures in artificial recharge systems

The study aims to identify a suitable site for open and bore well in a farmhouseusing ground magnetic survey in south India.It also aims to define depth to granitoid and structural elements which traverse the selected area.Magnetic data(n=84)measured,processed and interpreted as qualitative and quantitatively.The results of total magnetic intensities indicate that the area is composed of linear magnetic lows trending NE-SW direction and circular to semi-circular causative bodies.The magnetic values ranged from-137 nT to 2345 nT with a mean of 465 nT.Reduction to equator shows significant shifting of causative bodies in the southern and northern directions.Analytical signal map shows exact boundary of granitic bodies.Cosine directional filter has brought out structural element trending NE-SW direction.Results of individual profile brought to light structurally weak zone between 90 m and 100 m in all the profile lines.Sudden decrease of magnetic values from 2042 nT to 126 nT noticed in profile line 6 between 20 m and 30 m indicates fault occurrence.Magnetic breaks obtained from these maps were visualized,interpreted and identified two suitable sites for open and bore well.Radially averaged power spectrum estimates depth of shallow and deep sources in 5 m and 50 m,respectively.Euler method has also been applied to estimate depth of granitoid and structural elements using structural indexes 0,1,2,and 3 and found depth ranges from<10 m to>90 m.Study indicates magnetic method is one of the geophysical methods suitable for groundwater exploration and site selection for open and borewells.

Urban Waterfront: Subject of International Concern

Urban waterfronts are recognized as important formation elements of the social and urban identity of the city and as elements of their economic development.They constitute also a significant part of the city’s physiognomy.Approaching the port-cities by a historic and urbanistic perspective from the period of their initial development until approximately the end of the 18th century briefly,the reasons why the relationship between city and sea started to weaken are presented.There are records from the beginning of the 19th century that show the gradual severance of the city from its water element,followed by the intensification in the 20th century.The consequences of the Industrial Revolution on one hand and the World Wars on the other constituted the means of recognition for the need to be a simultaneous action not only for the layout of the space but also for its social and human contents,with a goal of improving the human environment(Benevolo,1990).Under these circumstances,the value of the waterfront was recognized,as far as the urban identity of the city is concerned.Furthermore,waterfronts were identified as an important factor for economic,social,and environmental overhaul of the cities.In this context of recognition,the rebuilding of the relationship between city and sea is attempted through focused interventions in urban waterfronts.In the end,the general goals and the tendencies of the waterfronts’redevelopments are presented.Moreover,the tactics of interventions as well as the effects of the initial transformations on waterfront cities are introduced.

Unfolded Drawings and Views for Irregular Spiral Surface Given Boundary Equations Based on CAD

Taking spiral chute as example, a method of unfolded drawings and views about irregular spiral surface is introduced. The surface is undevelopable and too complicated to get its views or to draw unfolded drawings by manual method. In this article, a series of the boundary equations of the spiral chute are derived by the movement rule of coal flow, and the solid and views of the spiral chute are generated based on redevelopment of SolidWorks. Unfolded drawing is drawn applying triangular development principle. The views and unfolded drawings not only are produced automatically, precisely and parameterized, but also involve more technological information. So it has an important significance on the irregular spiral surface＇s developments and processing.

Citizen Participation in Housing Requisition in Shanghai

The changing regulatory regime in Shanghai requires residents' participation to approve housing requisition decisions for inner-city redevelopment projects. Such policy reform creates a new discourse for urban redevelopment and housing requisition schemes. This article examines how and to what extent government authorities shape citizen participation in residential relocation and housing requisition in Shanghai. The analysis of this regulation regime helps us to better understand the importance of the role of residents in the decision-making of inner-city redevelopment. This article concludes by discussing policy implications of the regulations, including equitable outcomes particularly benefiting disadvantaged groups of people.
