1AbstractProperties of city-level commuting networks are expected to influence epidemic potential of cities and modify the speed and spatial trajectory of epidemics when they occur. In this study, we use aggregated mobile phone user data to reconstruct commuter mobility networks for Bangkok (Thailand) and Dhaka (Bangladesh), two megacities in Asia with populations of 16 and 21 million people, respectively. We model the dynamics of directly-transmitted infections (such as SARS-CoV2) propagating on these commuting networks, and find that differences in network structure between the two cities drive divergent predicted epidemic trajectories: the commuting network in Bangkok is composed of geographically-contiguous modular communities and epidemic dispersal is correlated with geographic distance between locations, whereas the network in Dhaka has less distinct geographic structure and epidemic dispersal is less constrained by geographic distance. We also find that the predicted dynamics of epidemics vary depending on the local topology of the network around the origin of the outbreak. Measuring commuter mobility, and understanding how commuting networks shape epidemic dynamics at the city level, can support surveillance and preparedness efforts in large cities at risk for emerging or imported epidemics.

The city has proved to be the most successful form of human agglomeration and provides wide employment opportunities for its dwellers. As advances in robotics and artificial intelligence revive concerns about the impact of automation on jobs, a question looms: how will automation affect employment in cities? Here, we provide a comparative picture of the impact of automation across US urban areas. Small cities will undertake greater adjustments, such as worker displacement and job content substitutions. We demonstrate that large cities exhibit increased occupational and skill specialization due to increased abundance of managerial and technical professions. These occupations are not easily automatable, and, thus, reduce the potential impact of automation in large cities. Our results pass several robustness checks including potential errors in the estimation of occupational automation and subsampling of occupations. Our study provides the first empirical law connecting two societal forces: urban agglomeration and automation's impact on employment.

This study aims to analyze the consequences of the gentrification process as a result of tourism on the elderly inhabitants. Firstly, the concept of gentrification is reviewed, a process that is no longer exclusive to large cities but has spread to smaller and lesser-known municipalities. A clear example of this type of new tourist destination is the city of Cáceres, a World Heritage medium-sized city where tourism is the basis of its economy. The research considers gentrification in medium-sized cities and its effect on active aging. Based on a qualitative methodological approach, a total of 32 in-depth interviews were conducted and analyzed to compare two neighborhoods—one gentrified and one not. The results show a remarkable disparity in the residents’ perceptions of their environment and their city. The findings suggest adverse effects on the quality of aging due to the gentrification process, such as family dependency, social-space disconnection, and a generally pessimistic image of the neighborhood. Consequently, the impact of tourism negatively affects the gentrified neighborhood inhabitants’ psychological, social, and emotional well-being.

Sporting events have become first-order promotional tools of large cities, allowing them to reach levels of dissemination economically unaffordable as conventional advertising. The social impact of the event on residents is very important, given their role as main actors. Perceptions of the residents of the cities that host sporting events have been extensively studied, although in this case a singular point of comparison to study the perception of the costs of organizing and holding the sporting event is provided. The purpose of this chapter is to assess the perception of the citizens of Valencia (Spain) on specific aspects of three sports events held in the city in 2012: European Grand Prix Formula 1, the Tennis Open 500, and Valencia Marathon. The results show significant differences in the perception of the costs of organizing the events related, and demonstrate the impact of the type of activity in the perception of residents.

The issue of increasing the efficiency of urban electric transport through the introduction of CASE-technologies based on SADT-methodology is considered. The performance of the system analysis of the operation of urban electric transport is given. The system of urban electric transport is considered not as an isolated system that solves only its problems - making a profit, but in connection with the problems of the city, the population that uses transport services, enterprises that employ people who transport. The proposed methodology will allow to create a computer functional model of operation of electric vehicles in the IDEF0 format using the software package BPWin. It is shown that the operation of transport is a complex process consisting of three subsystems: operation management, commercial and technical operation. Each of these subsystems has its own functional tasks, which require appropriate resources. Therefore, to ensure resource conservation in the operation of rolling stock, the following levels of development are presented and considered: the city transport system, urban electric transport enterprises, technological processes of passenger transportation, maintenance, maintenance and repair of facilities and equipment. Also operation of city electric transport includes maintenance of vehicles in depot. This article describes the features of the impact of the rolling stock of urban electric transport on energy consumption, taking into account the influence of factors such as passenger cabin occupancy, mileage of the mobile unit when operating on the routes of large cities, operating speed. A new methodology for evaluating the work of a city electric transport company is presented, which allows to combine several different, economically independent enterprises into one functional model. It is shown that the use of the proposed model will make it possible to create a system of accounting for electricity consumption by different types of urban electric transport.

AbstractWe study the spatio-temporal spread of SARS-CoV-2 in Santiago de Chile using anonymized mobile phone data from 1.4 million users, 22% of the whole population in the area, characterizing the effects of non-pharmaceutical interventions (NPIs) on the epidemic dynamics. We integrate these data into a mechanistic epidemic model calibrated on surveillance data. As of August 1st 2020, we estimate a detection rate of 102 cases per 1,000 infections (90% CI: [95 - 112 per 1,000]). We show that the introduction of a full lockdown on May 15th, 2020, while causing a modest additional decrease in mobility and contacts with respect to previous NPIs, was decisive in bringing the epidemic under control, highlighting the importance of a timely governmental response to COVID-19 outbreaks. We find that the impact of NPIs on individuals’ mobility correlates with the Human Development Index of comunas in the city. Indeed, more developed and wealthier areas became more isolated after government interventions and experienced a significantly lower burden of the pandemic. The hetero-geneity of COVID-19 impact raises important issues in the implementation of NPIs and highlights the challenges that communities affected by systemic health and social inequalities face adapting their behaviors during an epidemic.

AbstractResidential suburbanization is one of the most spontaneous processes occurring in the surroundings of large cities in Central and Eastern Europe. In the case of Wrocław, the first phase of suburbanization began as early as the second half of the 19th century. Its spatial scope changed with the expansion of the administrative borders of the city between 1924-28 and 1950-73, when dozens of suburban villages were incorporated into the city. In addition, during the socialism period, the intensity of suburbanization decreased significantly, which was related to the development of the city within the conditions of planned urbanization and industrialization of the country. The second phase of suburbanization began with the system transformation in the 1990s, and its scale and intensity increased in the 21st century. New construction in the hinterlands of the city has contributed to significant changes in the morphology of suburban villages, especially as the growing share of new buildings is multi-family housing. The aim of this article was to identify the most common trends in the morphological changes that affect villages located in the suburban area of Wrocław under the influence of residential suburbanization. Using the analysis of cartographic materials, field research and graph methods, a typology of morphological transformations of villages located in the suburban area was proposed.

During the late 1960s and early 1970s the Canadian government effected a turnabout in its urban renewal policy, which culminated in the launching of the Neighbourhood Improvement Program in 1973. This program differed from prior forms of renewal by emphasizing the preservation of the built environment and citizen participation in neighbourhood planning. This article is concerned with examining the difference in the attitudes the city administrations of Montreal and Toronto took toward the federal program, and the impact of this difference on the results in the two cities. It appears that Toronto's mode of implementation was in the spirit of the federal policy revision while Montreal endeavoured to pursue traditional urban renewal objectives through its use of the program. These two approaches to the Neighbourhood Improvement Program are depicted respectively as expressions of a participatory and a centralized mode of policy making at the local level.

The paper highlights the impact of excessive industrialization during the centralized economy era on urban spatial identity, as well as the disruption of this identity through political-administrative decisions, a phenomenon characteristic of the Central and Eastern European region during the era of centralized economies. The tendency to rebalance urban territorial systems is achieved through deindustrialization, together with reindustrialization and tertiarization. All these changes affect functionality, physiognomy as well as urban culture, and can be quantified through the changes in the memory of places. Urban toponyms related to industrialization are disappearing and are replaced by toponyms that illustrate the historical past of the city and, in general, its spatial identity. The paper aims to contribute to the development of research on the impact of oversized industrialization on the memory of places, in the context of the transition from industrial to service-based economies, a process that affected the states of the former Communist Bloc after 1990. Based on bibliographic sources and field research conducted between 2008 and 2020 in two cities in Romania (Bucharest, the country’s capital, and Galați, the largest river and seaport and the main centre of the steel industry in the country), we have evaluated quantitatively these changes with the help of indices resulting from the toponymic changes resulting from these processes. The study shows that the functional disturbances due to the oversized industrialization that characterized the communist period only managed to a small extent to affect the correlation between the spatial identity of the two cities and their toponymy.
