An Enhanced Multiview Transformer for Population Density Estimation Using Cellular Mobility Data in Smart City

This paper addresses the problem of predicting population density leveraging cellular station data.As wireless communication devices are commonly used,cellular station data has become integral for estimating population figures and studying their movement,thereby implying significant contributions to urban planning.However,existing research grapples with issues pertinent to preprocessing base station data and the modeling of population prediction.To address this,we propose methodologies for preprocessing cellular station data to eliminate any irregular or redundant data.The preprocessing reveals a distinct cyclical characteristic and high-frequency variation in population shift.Further,we devise a multi-view enhancement model grounded on the Transformer(MVformer),targeting the improvement of the accuracy of extended time-series population predictions.Comparative experiments,conducted on the above-mentioned population dataset using four alternate Transformer-based models,indicate that our proposedMVformer model enhances prediction accuracy by approximately 30%for both univariate and multivariate time-series prediction assignments.The performance of this model in tasks pertaining to population prediction exhibits commendable results.

Actual Value of Rural Cultural Auditorium Construction from the Perspective of Social Transformation:A Case Study of Wenzhou City

From the perspective of social transformation,this paper analyzed the actual value of the construction of Wenzhou rural cultural auditorium,and it was found that it has important value in promoting the transformation of rural culture,economy,and grassroots governance.The construction of rural cultural auditorium is helpful for improving the present backward status of rural public cultural service supply,and promoting the integration and development of rural culture and urban culture;cultivating new rural economic entities,injecting action force for rural economic transformation and development;providing space guarantee for citizen participation in rural grassroots social governance,and is favorable for enhancing the awareness of public participation in rural grassroots governance.However,in the context of comprehensive rural revitalization,the value of cultural auditorium construction has not yet been fully realized.It is necessary to further enhance its value in rural social transformation from three aspects:auditorium construction,daily activity undertaking,and residents'participation in cultivation.

Characteristics and Mechanism of Agricultural Transformation in Typical Rural Areas of Eastern China:A Case Study of Yucheng City,Shandong Province

Rural off-farm employment,rapid loss of agricultural land,and advanced technology popularization had led agricultural production in Chinese typical rural areas come at a critical transformation and upgrade stage.Based on sample survey data gathered from 401 households in Yucheng City,Shandong Province,this paper focuses on the characteristics and mechanism of agricultural transformation in typical rural areas of the eastern China.It was found that 74.3% of households surveyed kept at least one member engaging in off-farm employment,and 57.1% looked forward to expanding the operational scale of arable land,while just 13.7% had actually transferred their agricultural land.Since growing off-farm employment does not result in the collapse of traditional subsistence agriculture,therefore,agricultural production in Yucheng City is at an incomplete transformation phase from traditional small-holder farming to modern scale economy.It is caused by both macro environments and family characteristics,while urban-rural dual structure,imperfect rural development policy and agricultural technology popularization make peasant economy strengthen upon maintenance,and small-holder farming becomes peasant's natural response owing to pluriactivity,local off-farm employment,reverse elimination,etc.In order to achieve smooth agricultural transformation of typical rural areas in the eastern China,it needs to promote professional differentiation among peasants,under clear policies adopted by central government.Providing comprehensive services for agricultural production and improving production skills and knowledge of farmers who are still living in the countryside will effectively stimulate the process of agricultural transformation.

Geographical Space Development Zone Classification:An Essential Guide for Transformation of Mountain Resource Cities

Sustainable development of mountain areas and resource cities has been a significant issue worldwide. Transformation of mountain resource cities is facing tremendous difficulties. In the context of National Major Function-oriented Zone Planning raised to a national strategic level in China, it is important to effectively implement the planning by studying geographical space development zone classification of prefecture- and county-level cities based on their major function orientation. This research is even more critical for the transformation of mountain resource cities. In this study, we evaluated geographical space development suitability, and classified geographical space development zones for Dongchuan Distric in Kunming City of Yunan Province, China, a typical mountain resource city. A quantitative grid-based evaluation was conducted using key-factor identification and restrictive-supportive comprehensive index determinati based on a geographic information system framework with different source data. The results included a classification of geographical space of Dongchuan into five types: the prohibited development zone, the inappropriate development zone, the controlled development zone, the moderate development zone and the preferential development zone. The distribution characteristics of geographical space development zones showed that the proportion of the prohibited development zone is the highest, while that of the other four development zones is comparatively lower and significantly fragmented. The geographical space development suitability is greatly controlled by the geomorphic pattern. Although Dongchuan is extremely restrained in terms of suitable geographical space for industrialization and urbanization, it still has the certain preferential and moderate development zones with an area of 207.81 km2 with large parts being concentrated and contiguous, which makes these areas the most favorable for development. Only by adapting to this reality and implementing centralized development strategy in the regions with higher suitability may Dongchuan achieve smooth transformation from expansion mode to compact mode and its sustainable development capacity may be improved. Suggestions with an angle of industrial and spatial development pattern were put forward for the transformation of the city in future.

Urban structure transformation of Lhasa City after the peaceful liberation and democratic reform of Tibet

In Tibet, Buddhism coupled with its theocratic history has given its cities and urban areas unique forms and structures. As the political, religious, and economic center of Tibet, Lhasa City has a special urban form and has experienced typical urban transformation processes for a thousand years. The city has been experiencing significant urban structure transformation that has accompanied the socio-economic development in recent decades since the peaceful liberation and democratic reform of Tibet during the 1950 s. Hence, this study presents the time-series of urban structure changes in Lhasa City for the purpose of understanding the characteristics and mechanisms of transformation under the republican political system. First, the study illustrates the urban socio-economic changes of Lhasa City beginning in the 1950 s via statistical data analysis. We then divide the urban development into several stages. Subsequently, we identify the transformation characteristics of urban structure by investigating urban growth, street structure, land-use, and religious facilities via maps of the city from every development stage. This paper ultimately discusses the regulation of city transformation. This study clarifies several probable issues facing Tibetan cities and proposes suggestions for future urban development of Tibetan cities.

An Outlook of Housing Transformation in Dhaka City

This paper contributes to the view that urban housing in most cities in developing countries is different in nature and more extent than that operative in developed countries.It addresses the emergence of multi-storied apartments through transformation in residential areas in Dhaka,one of the populous cities in the world and largest metropolitan region in Bangladesh,with a particular reference to a study conducted at Rupangar Residential Area.It identifies the key forces and processes underlying Dhaka’s residential transformation and the advent of multi-storied apartments.Fragmentation of functions and the uses of building stocks in relation to the socio-economic aspects with local conditions were sought in the survey.The increasing housing demand is essentially fulfilling by multi-storied apartments and steadily transforming the landscape and lifestyle of huge urban dwellers in Dhaka.It reveals from the study that apartment living gains much popularity and the dominance of informal apartments over formal apartments is more evident.More distinctly,piecemeal apartment development by the informal developers provides affordable shelter to the highest segment of city dwellers and Rupnagar presents a reasoned scenario urban housing transformation in the capital of Bangladesh.

Theoretical Research,Practice Exploration and Policy Suggestions on Scenescape Development and Ecological Value Transformation in Chengdu’s Park City Construction

The“Park City”concept presents a new,urban development model that can be used as a guide for planning the growth of a city.Advancing the transformation of Chengdu into a park city is an important and unique strategic option for maintaining and strengthening the Chengdu-Chongqing economic circle.The construction of a park city in Chengdu has many potentially positive and favorable outcomes,including maintaining natural ecosystems while improving biodiversity,livability,and enhancing the city’s historical and cultural heritage,all while establishing Chengdu as a national leader for this new urban development model.In recent years,park city scenescape modeling and the resulting ecological value transformations have been analyzed through theory,mechanism designs,and limited practice,but throughout the explorations on scenescape building and ecological value transformations,the actual construction of a park city is still facing many problems.This article argues that Chengdu should take lessons from the advanced experience in urban ecological construction efforts of other cities,both in China and overseas,focusing on sustained scenescape building,theoretical research in ecological value transformations,establishing meaningful and compatible interaction mechanisms between ecological value transformations and capital markets,improving the levels of planning and designing needed for scenescape building,establishing innovative scenescape building and ecological value transformations management systems and mechanisms,and cultivating park city scenescape brands.Related and detailed scenescape building and ecological value transformation measurement and policy suggestions are also provided in this article.

A Study on the Translation of Love in a Fallen City from the Perspective of Three Dimensional Transformation of Eco-Translatology

Love in a Fallen City is one of Eileen Chang’s representative works and translated by Karen Kingsbury.The ecological environment of translation restricts and influences the translator’s choice of translation strategies,methods and techniques in the process of translation.According to the eco-translatology,translation is a transformation from language dimension,culture dimension and communication dimension.This article analyzes the three-dimensional transformation between the source language and the target language in the English version of Love in a Fallen City,and holds that a good translation must be the translator’s effective adaptation to the ecological environment including the source language,the source culture and the target culture.

Tanzimat Reforms and Urban Transformations in Ottoman Port-Cities

The 19th century was a milestone for urban planning history of the Eastern Mediterranean region since the typology of the Ottoman city was reformed,more or less abruptly,by strong Western European influences as a consequence of broader political,economic,and social transformations.From the very beginning of the 19th century,the Ottoman state confronted significant administrative issues that raised in the importance to institutionalise reforms over a long period of time,representing the foundation of later urban“modernisation reforms”.These challenges of the Ottoman cities at that period coincided with one crucial reform framework known as“Tanzimat”,which reflected the social willingness to inherit elements of European culture,technological innovations,and lifestyle.According to that direction,urban space was considered as a workshop of planning regulations and reforms adopting principles of contemporary,at that time,European urban planning,mostly applied in England and France.These social and urban reforms established by the Ottoman state marked the first attempt to relate Ottoman cities with European planning,urban infrastructures,building regulations,and public administration.During the period of Tanzimat(1839-1876),the economic role and impact of cities was strengthened reflecting a rising urbanisation of population.This article highlights this“Europeanisation”of Ottoman cities at the period of Tanzimat by investigating five case-study cities:Smyrna,Beirut,Alexandria,Thessaloniki,and Constantinople.All these cities were important ports-hubs of the Eastern Mediterranean whose urban development since the 1840s was a direct consequence of the modernisation reforms and,in general,an increase of European influence.These urban reforms,like in many European cities,included new transport infrastructures and communication networks,public services(water,gas,tramways,etc.),health and education,and new industrial patterns.

Effectiveness of Land Use Structure Evolution to Industrial Structure Transformation

Scarcity of land resources and transformation of industrial structure is a pair of contradictory elements.We derive the characteristics of land use structure and industrial structure transformation in Xining City using Transformation Coefficient(TC):first,in the period 1999-2000,the land use structure coefficient(θ1) declined by 79.55%,but the overall evolution trend is gentle;second,the transformation coefficient of industrial structure(θ2) tended to decline ceaselessly on the whole,a decrease of 36.09%(overall,the transformation coefficient of industrial structure is slightly greater than the land use structure coefficient);third,the inter-annual variation of the two experienced ups and downs(in the period 1999-2007,the inter-annual variation was great and in the period 2008-2010,the inter-annual variation tended to be gentle).On the basis of autocorrelation and co-integration model,we draw the following conclusions through analysis:first,the land use structure in Xining City plays a role in promoting industrial structure transformation;second,there is a long-term equilibrium relationship between the two.Finally,relevant policy recommendations are put forward for the industrial development in Xining City.

Conflicts in Defining Data Ownership in China’s Digital Transformation and the Regulatory Path

China is aggressively pursuing digital transformation,and data,alike labor,technology,capital,and knowledge,has become as a crucial factor of production.Digital transformation is accelerating the emergence of a data-intensive society,and the ensuing difficulties of balancing freedom and responsibility,openness and security,as well as free sharing and legal regulation are posing new challenges to national and social governance.Among these challenges,defining data ownership,the social disorder and anomie brought about by the unclear definition of data ownership,and data ownership regulatory path are new propositions that need to be urgently addressed in this data-intensive society.This paper systematically explains the theoretical meaning and practical value of data ownership through a literature review on the analysis of domestic and foreign scholars as well as research think tanks,compares the differences and inherent conflicts between the definition of data ownership by the government,enterprises,and society in China,thoroughly compares the definition standards of the European Union,the United States,and Japan,and on this basis,discusses the formation of a definition of data ownership that meets the requirements of China’s digital transformation.
