Abstract. The exploratory spatial analysis allows to describe patterns of spatial distribution, to identify clusters and outliers through specific techniques of spatial association and data model. The objective of the study is to verify the spatial autocorrelation between the mean prices of the housing obtained from web scraping technique in online platforms in the city of Salvador, on the coast of northeast Brazil. For this purpose, the Global Moran’s Index (which provides a general measure of association) and the Local Index of Spatial Association (LISA) were calculated. The results of Global Moran’s Index indicate positive autocorrelation between the mean prices of housing prices in the 163 districts of the municipally that are statistically significant, such as identification of clusters through LISA. Thus, the analysis allows to conclude the existence of a heterogeneous pattern in the distribution of these mean prices in the urban space of Salvador.

In Dakar, open space represents the real condition necessary for the expression of endogenous social emancipation, attributed a key role by the literature in mitigating the polarising effects of globalisation. This paper advances the hypothesis that, faced with reaching a critical threshold in the progressive saturation of unconstructed urban space, the design of constructed space and its borders in the Senegalese capital today assumes relative autonomy in supporting (or precluding) the informal process of the reappropriation of the city. This hypothesis, supported by the results of research in the field, is tested by the diachronic spatial analysis of a specific urban area - the waterfront - in part from the perspective of a radical change in the scenario of the urban development of Dakar.

The article considers the problem of open public spaces preserving – such as streets, squares, parks and other elements of the urban structure. The Council of Europe and UNESCO view urban spaces as a part of the city’s cultural landscape, as bearers of its identity and cultural memory, and their preservation as the key to the sustainable development of historic cities and the foundation of democracy. Therefore, the system of open spaces of the city should, according to the recommendations of UNESCO, be considered as a cultural heritage site, an integral part of the cultural landscape of the city. We can talk about the preservation of public urban spaces only when they are part of the network of pedestrian spaces of the city and have the appropriate function. However, defining the boundaries of the historical spatial planning system and the principles of its formation is also a problem. Steady fragments of the spatial planning system of the city, which have certain historical characteristics, are not always preserved as a whole urban development and in some places have the form of individual fragments. Methods of spatial analysis and environmental zoning are used to determine the compositional basis and degree of preservation of the spatial fabric of the city. The method of spatial analysis allows to formalize a complex multilevel pattern of urban fabric of the city, highlighting only the compositional-spatial aspects of perception; to identify the compositional structure of urban spaces. The method of environmental zoning is based on the identification of the most established links in its urban structure, namely - systems of open pedestrian urban spaces, of which the transit spaces (streets) determine the compositional structure and historical "ornament" of the street network, and spaces of stay (squares, intra-quarter spaces) - their social role and content, identity of the city.

Some of the increasingly evident contradictions between spatial planning and social policy in Mexico City are apparent in the way land use regulation folds into and articulates with exclusion and marginality. In downtown areas, regulatory approvals and various planning measures have facilitated the escalation of land and housing prices and more exclusionary forms of urban development. At the periphery, land use regulation now conditions access to urban services, property titles, and even some social programs for settlement areas designated as “informal.” Comparing the state’s role in planning at these distinct sites uncovers a pattern of selective and uneven spatial regulation in different socioeconomic territories of the city, characterized by “fast-track” development approvals in downtown areas and “slow-track” regularization of settlements in peripheral areas. The analysis suggests how this pattern of uneven spatial regulation contributes to (re)producing urban space in ways that call into question the local government’s stated support for the “right to the city.” Las geografías desiguales de la regulación espacial ponen de manifiesto algunas de las contradicciones cada vez más evidentes entre la planificación espacial y la política social en la Ciudad de México. En las áreas del centro, las aprobaciones regulatorias y varias medidas de planificación han facilitado el aumento de los precios de la tierra y la vivienda y formas más excluyentes de desarrollo urbano. En la periferia, la regulación del uso de la tierra ahora condiciona el acceso a servicios urbanos, títulos de propiedad e incluso algunos programas sociales para áreas de asentamiento designadas como “informales.” Comparar el papel del estado en la planificación en estos sitios distintos revela un patrón de regulación espacial selectiva y desigual en diferentes territorios socioeconómicos de la ciudad, caracterizados por aprobaciones “fast-track” de desarrollo en áreas del centro y regularización “slow-track” de asentamientos en áreas periféricas. El análisis se centra en cómo la regulación del uso de la tierra se enreda y articula con la exclusión y la marginalidad y cómo la regulación espacial desigual contribuye a (re) producir espacio urbano de manera que cuestione el apoyo declarado del gobierno local por “el derecho a la ciudad.”

Active transport to school (ATS) is a convenient way for adolescents to reach their recommended daily physical activity levels. Most previous ATS research examined the factors that promote or hinder ATS, but this research has been of a global (i.e., non-spatial), statistical nature. Geographical Information Science (GIS) is widely applied in analysing human activities, focusing on local spatial phenomena, such as distribution, autocorrelation, and co-association. This study, therefore, applied exploratory spatial analysis methods to ATS and its factors. Kernel Density Estimation (KDE) was used to derive maps of transport mode and ATS factor distribution patterns. The results of KDE were compared to and verified by Local Indicators of Spatial Association (LISA) outputs. The data used in this study was collected from 12 high schools, including 425 adolescents who lived within walkable distance and used ATS or MTS in Dunedin New Zealand. This study identified clusters and spatial autocorrelation, confirming that the adolescents living in the south of the city, who were female, attended girls-only schools, lived in more deprived neighbourhoods, and lived in neighbourhoods with higher intersection density and residential density used more ATS. On the other hand, adolescents who were male, attended boys-only schools, lived in less deprived neighbourhoods, had more vehicles at home, and lived in neighbourhoods with medium level intersection density and residential density used more ATS in the northwest of the city as well as some part of the city centre and southeast of the city. The co-association between spatial patterns of the ATS factors and the ATS usages that this study detected adds to the evidence for autocorrelation underpinning ATS users across the study area.

Drawing on field research and a survey of 150 Zimbabwean migrants in Johannesburg, this paper explores the dimensions of migrants’ transnational experiences in the urban space. I discuss the use of communication platforms such as WhatsApp and Facebook as well as other means such as telephone calls in fostering the embedding of transnational migrants within both the Johannesburg and the Zimbabwean socio-economic environments. I engage this migrant-embedding using Bourdieusian concepts of “transnational habitus” and “transnational social field,” which are migration specific variations of Bourdieu’s original concepts of “habitus” and “social field.” In deploying these Bourdieusian conceptual tools, I observe that the dynamics of South–South migration as observed in the Zimbabwean migrants are different to those in the South–North migration streams and it is important to move away from using the same lens in interpreting different realities. For Johannesburg-based migrants to operate within the socio-economic networks produced in South Africa and in Zimbabwe, they need to actively acquire a transnational habitus. I argue that migrants’ cultivation of networks in Johannesburg is instrumental, purposive, and geared towards achieving specific and immediate goals, and latently leads to the development and sustenance of flexible forms of permanency in the transnational urban space.

The subject of the article is an analysis of the three aspects of depicting urban space of Eastern Ukraine, focusing specifi cally on the Donbass region and the city of Kharkov as depicted in the novels Voroshilovgrad (2010) and Mesopotamia (2014) by Serhiy Zhadan. The urban space of Eastern Ukraine overlaps with the most important values that shape a person’s personality and aff ect her or his self-identifi cation. The city space is also a “place of memory” and experiences of generations that infl uence current events. In addition to the historical and axiological dimension, the imaginative aspect of space is also important. This approach is used by the author to describe the urban space as a functioning imagination or stereotypes associated with it as opposed to its realistic depiction.

This study examined Residents’ evaluation of turning transport infrastructure (road) to spaces for holding social ceremonies in the indigenous residential zone of Ogbomoso, Oyo State, Nigeria. Upon stratifying the city into the three identifiable zones, the core, otherwise known as the indigenous residential zone was isolated for study. Of the twenty (20) political wards in the two local government areas of the town, fifteen (15) wards that were located in the indigenous zone constituted the study area. Respondents were selected along one out of every three (33.3%) of the Trunk — C (local) roads being the one mostly used for the purpose in the study area. The respondents were the residents, commercial motorists, commercial motorcyclists, and celebrants. Six hundred and forty-two (642) copies of questionnaire were administered and harvested on the spot. The Mean Analysis generated from the respondents’ rating of twelve perceived hazards listed in the questionnaire were then used to determine respondents’ most highly rated perceived consequences of the practice. These were noisy environment, Blockage of drainage by waste, and Endangering the life of the sick on the way to hospital; the most highly rated reasons why the practice came into being; and level of acceptability of the practice which was found to be very unacceptable in the study area. Policy makers should therefore focus their attention on strict enforcement of the law prohibiting the practice in order to ensure more cordial relationship among the citizenry, seeing citizens’ unacceptability of the practice in the study area.

O objetivo que permeia a presente pesquisa é utilizar a Fortaleza de Santa Cruz, localizada no bairro de Jurujuba, em Niterói, construída em 1555, na entrada da barra da Baía de Guanabara, como foco de antílise, ressaltando a importância deste fixo social enquanto atração turística e de lazer, incluindo a cidade de Niterói no circuito destas atividades, complementares à cidade do Rio de Janeiro; além de abordar conceitos e categorias analíticas, oriundos das ciências sociais, principalmente provenientes da Geografia, pertinentes ao estudo das atividades em tela. Neste contexto, na dinâmica espacial da cidade de Niterói, o processo de mudança de função dos fixos sociais têm sido extraordinário. Residencias unifamiliares, prédios e até mesmo fortificações militares, verdadeiras monumentalidades, foram refuncionalizadas, passando por um processo de turistificação. Assim, a refuncionalização da respectiva Fortaleza em espaço cultural toma-se um importante atrativo da história, do patrimônio, da cultura, marcando no espaço urbano sua expressões e monumentalidade, criada pelo homem como símbolo de seus ideais, objetivos e atos, constituindo-se em um legado as gerações futuras, formando um elo entre passado, presente e futuro. Abstract This paper focuses on Santa Cruz Fortress, built in 1555 in Jurujuba (Niterói), to guard the entrance of Guanabara bay, and stresses its role as a towist attraction and leisure' area, as a social fix which links the city of Niterói to the complementary circuit of these activities in the city of Rio de Janeiro. The study uses important concepts and analytic categories fiom social sciences, particularly fiom Geography.In the spatial dynamic of the city of Niterói, change in functions of social fuces has been extraordinary. Single-family dwellings, buildings and even military installations have been re-functionalized, undergoing a process of touristification. In that way, the refunctionalization of the Fortress as a cultural space provides an important attraction in the domains of history, patrimony, and culture, providing the urban space with an expression of monumentality, created by man as a symbol of his ideals, aims and actions, a legacy to future generations forming a link between past, present and future.
