An empirical test is made of the spatial transferability of a decompositional multiattribute preference model, in the context of spatial shopping behaviour. The model which is estimated for the city of Maastricht is used to predict shopping patterns in a part of the city of Eindhoven. The results indicate that the goodness of fit of the model reduces only slightly. This supports the assumption that decompositional preference models may be used to uncover utility or preference functions which are independent of spatial structure.

The aim of the current study is to provide an empirical test of containment theory of Walter Reckless (1899–1988). The theory proposes that outer and inner containment hold adolescents back from delinquency even when external factors pull and push them toward it. This early control theory was ahead of its time, but never received the empirical attention it deserves. This article outlines the core theoretical concepts and the basic propositions in order to empirically examine their validity. We employed hybrid linear regression analysis using longitudinal survey data of 612 adolescents (12–18 years old) in the city of The Hague, the Netherlands. The results indicate that outer and inner containment can be meaningfully distinguished, and that several but not all propositions of the theory are supported. Inner and outer containment function as a buffer against external pulls and are able to counteract the effect of increases in environmental pulls during adolescence. We conclude that containment theory is still a promising interaction theory that can help us understand why adolescents who experience external pulls toward delinquency are able to resist these influences.

The article describes the risks for the mental health and wellbeing of urban-dwellers in relation to changes in the spatial structure of a city that could be caused by the COVID-19 pandemic. A year of lockdown has changed the way of life in the city and negated its principal function as a place of various meetings and social interactions. The danger of long-term isolation and being cut-off from an urban lifestyle is not only a challenge facing individuals, but it also creates threats on various collective levels. Hindered interpersonal relations, stress, and the fear of another person lower the quality of life and may contribute to the development of mental diseases. Out of fear against coronavirus, part of the society has sought safety by moving out of the densely populated city centres. The dangerous results of these phenomena are shown by research based on the newest literature regarding the influence of COVID-19 and the lockdown on mental health, urban planning, and the long-term spatial effects of the pandemic such as the urban sprawl. The breakdown of the spatial structure, the loosening of the urban tissue, and urban sprawl are going to increase anthropopressure, inhibit access to mental health treatment, and will even further contribute to the isolation of part of the society. In addition, research has shown that urban structure loosening as a kind of distancing is not an effective method in the fight against the SARS-COV pandemic. Creating dense and effective cities through the appropriate management of development during and after the pandemic may be a key element that will facilitate the prevention of mental health deterioration and wellbeing. It is also the only possibility to achieve the selected Sustainable Development Goals, which as of today are under threat.

The article analyzes the processes of suburbanization and transformation of the spatial structure of the city of Ulan-Ude. Modern trends in the growth of Western and historical factors of development, due to socio-economic and historical factors of development. In the 1990s-2000s, because of the decline in agriculture and, as a result, the lack of jobs, the rural population began to migrate massively to the Buryat Republic’s capital. However, the prices for houses and apartments in the city center were unbearable for many migrants, so the purchase of land plots and the construction of houses were affordable for many. The estrangement of agricultural lands and their inclusion in residential areas allowed the city of Ulan-Ude and suburban areas to somewhat expand the territory of settlements and create a huge number of GNPP (gardeners non-profit partnership) and DNPP (dacha non-profit partnership). The city and suburban areas were not ready for such a flow and were not able to provide the newly arrived migrants with social, road transport and communal infrastructure. As a result, the city was surrounded by a suburbia almost devoid of any infrastructure. There are some elements of false urbanization or squatter area, which is a type of urbanization in which the urban population rapid growth is not accompanied by a commensurate increase in urban functions. In recent years, the growth rate of suburban settlements has decreased, mainly due to mortgages, which have become more affordable for the population and the growth of multi-storey construction. In addition, the village is slowly depleting the human resources that feed the city and the suburbs. In other words, those who wanted to move to the city have already moved

AbstractThe migration of city dwellers to suburbs is a commonly observed phenomenon. The growth of residential areas on the fringes of cities is referred to as suburbanisation. In the present study, migration patterns were investigated in rural districts located in the direct vicinity of the administrative boundaries of Olsztyn over a 10-year timespan. Several hundred building plot purchase/sale transactions in the form of notarial deeds were analysed to determine the dwelling place of the buyer. The analysis of the transactions revealed that the dominant group of purchasers were owners of apartments in multi-family precast concrete buildings, located in the city quarter closest to the studied suburbs. Changes in the spatial structure of suburban areas were also noted.

The paper is based on the author’s monograph (Śleszyński, 2008). It presents the analysis of enterprise headquarters’ locations in eight largest Polish cities (Warsaw, Szczecin, The Tricity [Gdańsk–Gdynia–Sopot], Poznań, Łódź, Wrocław, Katowice and Krakow). The study primarily involved data from the Hoppenstedt Bonnier database for the year 2004, concerning 3810 entities whose overall revenue exceeded the minimum of 15.6 million PLN. The businesses were analysed in terms of their location with respect to the city centre, as well as the differentiation of revenues, line of business and ownership structure. The analyses helped in the formulation of the basic regularities of the location distribution. For instance, it was found that spatial concentration is most significant in the case of the largest enterprises, the public sector and more advanced businesses, particularly high-order services.The location of large company headquarters, as well as their mutual connections, performs one of the key roles (or even the most important one) in the development of Central Business Districts in Polish cities during transformation.

AbstractThis introductory chapter provides a brief overview of the theories and models that constitute what has come to be called urban science. Explaining and measuring the spatial structure of the city in terms of its form and function is one of the main goals of this science. It provides links between the way various theories about how the city is formed, in terms of its economy and social structure, and how these theories might be transformed into models that constitute the operational tools of urban informatics. First the idea of the city as a system is introduced, and then various models pertaining to the forces that determine what is located where in the city are presented. How these activities are linked to one another through flows and networks are then introduced. These models relate to formal models of spatial interaction, the distribution of the sizes of different cities, and the qualitative changes that take place as cities grow and evolve to different levels. Scaling is one of the major themes uniting these different elements grounding this science within the emerging field of complexity. We then illustrate how we might translate these ideas into operational models which are at the cutting edge of the new tools that are being developed in urban informatics, and which are elaborated in various chapters dealing with modeling and mobility throughout this book.

This work analyzes the characteristics of the small-scale fading distribution in vehicle-to-vehicle (V2V) channels. The analysis is based on a narrowband channel measurements campaign at 5.9 GHz designed specifically for that purpose. The measurements were carried out in highway and urban environments around the city of Valencia, Spain. The experimental distribution of the small-scale fading is compared to several analytical distributions traditionally used to model the fast fading in wireless communications, such as Rayleigh, Nakagami-m, Weibull, Rice, andα-μdistributions. The parameters of the distributions are derived through statistical inference techniques and their goodness-of-fit is evaluated using the Kolmogorov-Smirnov (K-S) test. Our results show that theα-μdistribution exhibits a better fit compared to the other distributions, making its use interesting to model the small-scale fading in V2V channels.

This chapter studies the dynamics of Bogotá Region based on the New Economic Geography and the recent works on economic development in two big dimensions: the economic and the spatial structure; that is, productivity and polycentrism. The central thesis, supported on an econometric exercise for SMEs in 20 cities in Bogotá-Sabana region, is that with greater strength in the interior of Bogotá and less in the city region, a transition from monocentrism to functional polycentrism is consolidating. Krugman's Edge Cities model concludes that polycentrism comes from a process of spontaneous self-organization and produces a territorial order according to the mysterious ZIP law and consistent with efficiency, equity, and sustainability.
