AbstractIn designing the city of the future, city managers and urban planners are driven by specific citizens’ behaviors. In fact, economic and financial behaviors, and specifically, which goods and services citizens purchase and how they allocate their spending, are playing a central role in planning targeted services. In this context, cashless payments provide an invaluable data source to identify such spending behaviors. In this work, we propose a methodology to extract the consumption behaviors of a large sample of customers through credit card transaction data. The main outcome of the methodology is a concise representation of the economic behavior of people residing in a city, the so-called city consumption profile. We inferred the city consumption profile from a network-based representation of the similarity among the customers in terms of purchase allocation; on top of which we applied a community detection algorithm to identify the representative consumption profiles. By applying the above methodology to a set of credit card transactions of an Italian financial group, we showed that cities, even geographically close, exhibit different profiles which makes them unique. Specifically, usage patterns focused on a single type of good/service—mono-categorical consumption profile—are the main factors leading to the differences in the city profiles. Our analysis also showed that there is a group of consumption profiles common to all cities, made up by purchases of primary goods/services, such as food or clothing. In general, the city consumption profile represents a tool for understanding the economic behaviors of the citizens and for comparing different cities. Moreover, city planners and managers may use it in the outline of city services tailored to the citizens’ needs.

This article analyzes how the Poles and Jews who disappeared from the western Ukrainian city of L'viv as a result of the Second World War are remembered in the city today. It examines a range of commemorative practices, from monuments and museums to themed cafes and literature, and analyzes how these practices interact to produce competing mnemonic narratives. In this respect, the article argues for an understanding of the city as a complex text consisting of a diverse range of mutually interdependent mnemonic media produced by a range of actors. The article focuses in particular on the ways in which Ukrainian nationalist narratives interact with the memory of the city's “lost others.” The article also seeks to understand L'viv‘s memory culture through comparison with a range of Polish cities that have faced similar problems with commemorating vanished communities, but have witnessed a deeper recognition of these communities than has been the case in L'viv. The article proposes reasons for the divergences between the memory cultures of L'viv and that found in Polish cities, and attempts to outline the gradual processes by which L'viv‘s Polish and Jewish pasts might become more widely integrated into the city's memory culture.

To boost energy efficiency in the building sector at urban and district scales, the use of a Geographic Information System (GIS) for data collection and energy spatial analysis is relevant. As highlighted in many studies on this topic reported in literature, the correlation among available databases is complex due to the different levels of information. As the first part of a wide research aimed at estimating the energy demand of urban buildings, we present in this article a focus on the details of the GIS-based procedure developed to assess the main energy-related features of existing building stocks. The procedure is based on the elaboration of data from the Italian Topographic Databases, under provision at the national level according to the INSPIRE European Directive and the national General Census of Population and Houses. It enables one to calculate and map the urban built volume characterized by mostly diffuse use categories in an urban context (residential and offices), to which different equipment and building usage patterns can be associated, and by construction periods, featuring different technological solutions. The method has been applied to the city of Milan (Italy). An insight into the outcomes from the overall method of the wider research is also reported.

Bicycle-sharing systems (BSSs) have become a prominent feature of the transportation network in many cities. Along with the boom of BSSs, cities face the challenge of bicycle unavailability and dock shortages. It is essential to conduct rebalancing operations, the success of which largely depend on users’ demand prediction. The objective of this study is to develop users’ demand prediction models based on the rental data, which will serve rebalancing operations. First, methods to collect and process the relevant data are presented. Bicycle usage patterns are then examined from both trip-based aspect and station-based aspect to provide some guidance for users’ demand prediction. After that, the methodology combining cluster analysis, a back-propagation neural network (BPNN), and comparative analysis is proposed to predict users’ demand. Cluster analysis is used to identify different service types of stations, the BPNN method is utilized to establish the demand prediction models for different service types of stations, and comparative analysis is employed to determine if the accuracy of the prediction models is improved by making a distinction among stations and working/nonworking days. Finally, a case study is conducted to evaluate the performance of the proposed methodology. Results indicate that making a distinction among stations and working/nonworking days when predicting users’ demand can improve the accuracy of prediction models.

Introduction. Biometeorological circumstances have a big influence on all traffic participants, especially reflexes, moving coordination and perception ability. With a lower attention and drivers? and pedestrians? concentration, there was a larger amount of pedestrian trauma in certain biometeorological phases. Objective. The aim of this study was to establish the correlation between pedestrian trauma and biometeorological phases. Methods. The comparative analysis of everyday biometeorological phases for the city of Kragujevac determined by RHMI and the evidence of knocked-down pedestrians from the Kragujevac traffic police for the period 2003-2008. Results. There were 6,127 accidents, with 696 knocked pedestrians in 666 (10.87%) accidents. Most of them happened in 2003 (135), and the fewest in 2005 (90). Most accidents were during December (74), the fewest were in June (46). The fewest accidents were during 04-05-06 hour interval (by 2), most during 13-14 hours (61). There were 374 males and 349 females. Most of the males (by 60) were 0-10 and 11-20 years old, most of the females (74) were 11-20 years old. There were 443 pedestrians who suffered slight body injuries (112 were 11-20), 225 suffered heavy and 28 had lethal injuries (most over 70). As provokers, the pedestrians suffered because of improper crossing roads (185), while as a casualties, they suffered due to speeding of vechicles (285). Most accidents happened in biometeorological phases 4 (168) and 9 (151), the fewest in phase 10 (4). Conclussion. Statistical analysis shows a significant correlation between pedestrians? accidents and biometeorological phases, when the most accidents occurred during penetrations of cold fronts, while there was a sudden switch of weather conditions from warm-dry to cold-wet weather.

Comparative analysis of cluster instruments for economic development of Ukraine and Vietnam is carried out. The study showed that the absolute majority of the clusters operating in Ukraine have significant strategic gaps between strategic goals and resources for their implementation. In order to eliminate strategic gaps, a set of practical recommendations has been substantiated, which generally consists of the following main elements: inclusion in the current legislation of the concept of "innovative industrial cluster of the sixth technological order"; providing the subjects of such clusters with innovative tax benefits; provision of concessional lending for intra-cluster innovation projects. In terms of the effectiveness of the use of cluster instruments for economic development, Vietnam is significantly ahead of Ukraine. The highest efficiency of cluster development was achieved in Vietnam for fourteen of the sixteen positions we analyzed, and in Ukraine, the highest efficiency was not achieved for any position. For each of the ten cluster instruments of economic development that are not used in Ukraine, we substantiated the feasibility and effectiveness of their implementation in our state. In order to introduce each of the most important cluster instruments of economic development, an appropriate legislative framework should be created in Ukraine, as well as a system of by-laws for its practical implementation. Vietnam has been well done in the cluster industrial policy. To the end of 2020, there are 260 industrial parks in the whole country (besides, there are some industrial parks acquired licensing but not yet constructed or having planned but not yet approved). Hanoi plans to build 43 industrial clusters in 2021. To ensure efficient operation of industrial clusters, Hanoi would provide supporting policies for enterprises and business households relocating their operation into industrial clusters, while setting up a list of service fees for all industrial clusters in the city. Hanoi plans to further promote investment and higher occupancy rate in industrial clusters, gradually transforming the current management model towards greater efficiency in operation of industrial clusters.

Attempt of comparative analysis of the segetal flora of Siedlce City with similar flora of areas of arable lands of the Siedlce Upland is presented in the paper. Received results show the larger value for urban flora of apophitysm coefficient - 63,3% (61% for Upland), flora modernization - 0,52 (0,42 for Upland) and flora lability - 19 (15 for Upland). On the other hand segetal flora of the Siedlce Upland is characterised by larger synanthropization coefficient - 104 (93 for the city). As to other differences, considerable larger participation of perennial species in the flora of the city (45,5% Siedlce; 37,1% Upland) is noteworthy. Moreover the occurrence of juvenile forms of arborescent species and plants running wild from gardens and parks, e.g.: <i>Mathiola incana, Aesculus hippocastanus, Sedum reflexum, Nigella damascena, Helianthus tuberosus</i> among species weeding urban cultivation is clearly noticeable.
