Abstract The aim of this analysis is to examine the characteristics of the Airbnb network, to verify the share of Airbnb offers that belong to the sharing economy and to identify the differences between the spatial distribution of the Airbnb network and the traditional hotel industry. The article is based on a unique dataset of web-scraped data on Airbnb listings in Warsaw (Poland), combined with district-level official statistics on the hotel industry. The analysis shows that only approximately 11% of offers belong to the sharing economy (“individuals granting each other temporary access to their under-utilised assets”), while at least one third of offers are provided by professional firms. The Airbnb network shows a strong centre-periphery pattern, with 75% of offers located within a range of 4.3 kilometres from the centre. The spatial concentration of Airbnb offers is strongly driven by their distance from metro lines, while it is weakly related to the amount of living space. On the district-level, the spatial distribution of Airbnb listings is correlated with that of the hotel industry, although Airbnb contributes to a more even spread of tourism in the city. The major contribution of this analysis is its presentation of the size and characteristics of the platform, which is essential for data-driven policy making.

En el marco de la pregunta por las diferencias y desigualdades metropolitanas, este artículo se propone estudiar la distribución espacial de la población extranjera en la Ciudad de Buenos Aires a partir de una tipología de contextos urbanos o tipos de hábitat, definidos en función del periodo de urbanización y la forma de producción del espacio habitacional. Tomando como fuente investigaciones previas y datos del Censo Nacional de Población, Hogares y Viviendas 2010, se realiza un análisis cuantitativo que indaga cómo se articula la diferenciación por condición migratoria con estos entornos que conforman la estructura socioespacial de la ciudad.Abstract:Within the framework of the question of metropolitan differences and inequalities, this article seeks to study the spatial distribution of the foreign population in the City of Buenos Aires on the basis of a typology of urban contexts or types of habitat, defined in terms of the period of urbanization and the form of production of the living space. Based on previous research and data from the National Census of Population and Housing 2010, a quantitative analysis is undertaken to explore how differentiation by migratory condition is linked to these environments that comprise the socio-spatial structure of the city.

Densification by greening, or what we can learn from Singapore (essay) Singapore, a city-state with a high population density, wants to give its population, its tourists and its economy a living and livable city and has developed the concept of the Garden City. Parks, nature reserves, forest, green corridors, trees, botanical gardens, horizontal and vertical greening of buildings, as well as popular participation, are all important for this vision of the city. Singapore is counting on dense construction alongside “greening” and biodiversity. Let us be prepared to learn from Singapore's example! Our land is also a non-renewable resource. To protect our ever more limited agricultural land, we should renounce any extension of building land, and free ourselves from the expanding carpets of suburban development. Let us build multiple urban neighbourhoods with mixed use and more biodiversity. Let us develop new types of communal gardens. Urban gardens in the widest sense – from private gardens to garden cooperatives, to parks and botanical gardens – are a part of our living space. The city should be our garden.

Lichen Flora

The spatial distribution of corticolous lichens on the iconic New Zealand pōhutukawa (Metrosideros excelsa) tree was investigated from a survey of urban parks and forests across the city of Auckland in the North Island of New Zealand. Lichens were identified from ten randomly selected trees at 20 sampling sites, with 10 sites classified as coastal and another 10 as inland sites. Lichen data were correlated with distance from sea, distance from major roads, distance from native forests, mean tree DBH (diameter at breast height) and the seven-year average of measured NO2 over the area. A total of 33 lichen species were found with coastal sites harboring significantly higher average lichen species per tree as well as higher site species richness. We found mild hotspots in two sites for average lichen species per tree and another two separate sites for species richness, with all hotspots at the coast. A positive correlation between lichen species richness and DBH was found. Sites in coastal locations were more similar to each other in terms of lichen community composition than they were to adjacent inland sites and some species were only found at coastal sites. The average number of lichen species per tree was negatively correlated with distance from the coast, suggesting that the characteristic lichen flora found on pōhutukawa may be reliant on coastal microclimates. There were no correlations with distance from major roads, and a slight positive correlation between NO2 levels and average lichen species per tree.

This paper questions the ‘seeing like a city’ vs. ‘seeing like a state’ opposition through a detailed discussion of urban politics in the city of Paris, France, a prime example of the ways in which the national remains a driving dimension of city life. This claim is examined by a consideration of the shortcomings of Paris’s recent and timid commitment local democracy, lacking recognition of the diversity of its citizens, and the ways in which the inclusion of more women in decision-making arenas has failed to advance the ‘feminization of politics’. A common factor in these defining features of the Hidalgo administration seems to be the prevalence of ‘femonationalism’ and its influence over municipal policy-making.

Tent encampments have become an especially common form of homelessness in West Coast cities like Oakland, California, where the number of people living in tent encampments increased by 130 percent between 2017 and 2019. Living in tent encampments provides residents both benefits and risks, depending on the encampments’ location, size, and stability. Using data from Google Street Views, I document the growth and spatial dynamics of tent encampments in west and central Oakland over the last decade. The number and size of tent encampments rapidly increased between 2014 and 2019, varying widely in their stability. City interventions like the city’s outdoor transitional housing sites displaced several large tent encampments. Combined with overall tent encampment growth, these displacements dispersed the encampments throughout nearby neighborhoods and other parts of the city.

This commentary interrogates what it means for routine urban behaviours to now be replicating themselves computationally. The emergence of autonomous or artificial intelligence points to the powerful role of big data in the city, as increasingly powerful computational models are now capable of replicating and reproducing existing spatial patterns and activities. I discuss these emergent urban systems of learned or trained intelligence as being at once radical and routine. Just as the material and behavioural conditions that give rise to urban big data demand attention, so do the generative design principles of data-driven models of urban behaviour, as they are increasingly put to use in the production of replicable, autonomous urban futures.

AIMS: This research aims to determine the epidemiology and the spatial distribution of intestinal parasitosis in the city of Teresina.METHODS: A cross-sectional study was carried out based on the data of parasitological fecal exams performed in the Laboratory Raul Bacelar between January, 2014 and July, 2017. In addition to the prevalence of intestinal parasitosis and polyparasitism, we verified the association of these diseases with gender, zone and period of the year by means of the chi-squared test, whereas the relation with age was analyzed by the Mann-Kendall tests and multiple comparisons of age classes. The spatial distribution was performed using the QGIS georeferencing software.RESULTS: The prevalence of enteroparasitosis in Teresina is 17,8% with Ascaris lumbricoides being the most common species, due to the precarious sanitary conditions of the city. The prevalence of individuals with polyparasitism is 3,13%, in which an association between the species Entamoeba coli and Entamoeba histolytica/dispar was found. There was no relation between intestinal parasitosis with gender, but we verified that individuals in rural areas are more susceptible to these diseases. The species Ascaris lumbricoides and Entamoeba histolytica/dispar occur more frequently in the first and second semester, respectively. We observed that there is an apparent tendency to increase cases of E. histolytica/dispar and reduction of cases of Giardia sp. according to aging. Mapping intestinal parasitosis showed us that there is a prevalence between one and 20% in most of Teresina's neighborhoods, and Ascariasis embodies at least 40% of cases of enteroparasitosis in these neighborhoods.CONCLUSIONS: Investments in basic sanitation and new epidemiological investigations must be carried out to control intestinal parasitosis in Teresina, emphasizing that children and the elderly should be considered priority groups in these programs.
