Abstract Worldwide there is accumulated evidence of heatwave intensification due to climate change. Regional differences in the effects of heatwaves require local studies to implement public mitigation and adaptation strategies. This work analyzes and characterizes heatwaves’ occurrence for the city of Campinas, Brazil, through an observational study from 1956 to 2018. The definition of heatwaves adopted requires that the maximum and minimum daily temperatures be above the daily limits derived from climate normal 1961-1990. The annual and seasonal metrics of the number, frequency, and heatwaves’ duration showed significant and positive trends, except in winter. We found that the longest, the more intense, and the most frequent events occurred in the last 20 years and that a significant change in trend occurred at the beginning of the 1980s. Lastly, we performed an exploratory study of intra-urban variability, comparing heatwave metrics between two different weather stations that are 30 km apart in the city of Campinas. We found similar metrics patterns for the two weather stations, with more prolonged and more frequent heatwave events for the region's station with a higher rate of urban land occupation.

The qualitative and clear definition of the legal regime of the capital of Ukraine, the hero city of Kyiv, is influenced by its legislative enshrinement, however, it should be noted that discussions are ongoing and one of the reasons for the unclear legal status of the capital is the ambiguity of current legislation in this area. Separation of the functions of the city of Kyiv, which are carried out to ensure the rights of citizens of Ukraine and the functions that guarantee the rights of the territorial community of the city of Kyiv. In the modern world, in legal doctrine and practice, the capital is understood as the capital of the country, which at the legislative level received this status and, accordingly, is the administrative and political center of the state, which houses the main state bodies and diplomatic missions of other states. It is the identification of the boundaries of the relationship between the competencies of state administrations and local self-government, in practice, often raises questions about their delimitation and ways of regulatory solution. Peculiarities of local self-government in Kyiv city districts are defined in the provisions of the Law on the Capital, which reveal the norms of the Constitution in these legal relations, according to which the issue of organizing district management in cities belongs to city councils. Likewise, it is unregulated by law to lose the particularity of the legal status of the territory of the city. It should be emphasized that the subject of administrative-legal relations is not a certain administrative-territorial entity, but the social group is designated - the territorial community of the city of Kiev, kiyani. Thus, the provisions on the city of Kyiv partially ignore the potential of the territorial community.

In a general context of real estatespeculation, where rents and land prices are expensive, and a policy ofselective and limited housing, popular sectors can have access to a spacein the city through land occupation. In front of these conflicts, the Statein its different levels and powers, displays a form of intervention basedon the criminalization of struggles for land and housing. At the sametime, the national executive creates the Secretariat of Access to Habitat,oriented to allow political intervention for the regularization of settlements.However, this intervention tends to re-register the housing problems in thepolitical arena, reducing it to a conflict “between parties” and eluding theresponsibility of the State.From a qualitative methodological approach, we selected as empirical referencethe case of the settlement of Villa Obrera in Fiske, Menuco (GeneralRoca).

This article explores the experience of living among diverse infrastructural configurations in Ulaanbaatar, Mongolia, and forms of stigmatisation that arise as a result. In this capital city that experiences extremely cold winters, the provision of heat is a seasonal necessity. Following a history of socialist-era, centrally provided heating, Ulaanbaatar is now made up of a core area of apartments and other buildings undergoing increased expansion, surrounded by vast areas of fenced land plots ( ger districts) not connected to centrally provided heating. In these areas, residents have historically heated their homes through burning coal, a technique that has resulted in seasonal air pollution. Expanding out from Wacquant’s definition of territorial stigmatisation, this article discusses the links between heat generation, air pollution and environmental stigmatisation arising from residents’ association with or proximity to the effects of heat generation and/or infrastructural lack. This type of stigma complexifies the normative divide between the city’s two main built areas. Residents’ attempts to mitigate forms of building and infrastructural ‘quality’ or chanar (in Mongolian) form ways of negotiating their position as they seek different kinds of property. Here, not only are bodies vulnerable to forms of pollution (both air and otherwise), but also buildings and infrastructure are vulnerable to disrepair. Residents’ assessments of infrastructural and building quality move beyond any categorisation of them being a clear ‘resistance’ to deteriorating infrastructural conditions. Instead, an ethnographic lens that positions the viewpoint of the city through these residential experiences reveals a reconceptualisation of the city that challenges infrastructurally determined normative assumptions.

Background and Objectives: To perform a retrospective report on the lethality of COVID-19 in different realities in the city of Rio de Janeiro (RJ). Materials and Methods: We accomplished an observational study by collecting the data about total confirmed cases and deaths due to COVID-19 in the top 10 high social developed neighborhoods and top 10 most populous favelas in RJ to determine the case-fatality rate (CFR) and compare these two different realities. Results: CFR was significatively higher in poverty areas of RJ, reaching a mean of 9.08% in the most populous favelas and a mean of 4.87% in the socially developed neighborhoods. Conclusions: The social mitigation measures adopted in RJ have benefited only smaller portions of the population, excluding needy communities.

AbstractThis article examines how the South African government, realizing the country's vulnerability to climate change, deemed it necessary to strengthen adaptation and mitigation measures and put in place legal and institutional frameworks to ensure implementation and compliance. Government must take responsibility for industry's inaction by implementing policies on climate change and, more importantly, through a visible change in government policy to hold industry accountable. The stringent policies and strategies being put in place are reducing vulnerability and also enhancing a broad spectrum of capacity in responding to environmental, climatic, resource and economic perturbations. The article further reviews state of the art methods and tools available to strengthen mitigation and adaptation strategies and measures in the areas of the existing frameworks regarding climate change. It also considers various measures by Eskom in particular, and strategies embarked upon by South Africa's national and local governments to reduce greenhouse gas emissions.

In the last decade, in the mining district of Zaruma-Portovelo, there has been significant land subsidence related to uncontrolled mining activity. The purpose of this work was to carry out a surface and underground geomechanical characterization of a mining sector north of the city of Zaruma that allows the definition of potentially unstable areas susceptible to the mass movement. The methodology used consists of the following stages: (i) compilation of previous studies; (ii) surface and underground characterization of rocky material to establish its susceptibility to mass movement; (iii) interpretation of results; and (iv) proposal of action measures. Among the most relevant results, it stands out that 26.1% of the 23 stations characterized on the surface present conditions that vary from potentially unstable to unstable. In underground galleries, the studied mean values of the 17 stations indicate that the rock has a medium to good quality, representing a medium susceptibility to gallery destabilization. The results obtained for the surface areas (depths up to 50 m, where altered materials predominate) and the underground areas (depths > 50 m, where the alterations are specific) can be used to identify the areas with a more significant potential for instability. For both cases, it has been possible to define specific monitoring, control, and planning actions for sensitive areas.

ABSTRACT Objective: Observe the workflow of nurses in hospitalization units identifying indirect care activities/interventions; measure the frequency and average time spent in performing them; and to verify the associations between average time of the activities interventions grouped into categories and per hospitalization unit. Method: Observational exploratory study using the timed technique. It was conducted in medical, surgical and specialized clinic units of a teaching hospital in the northwest of São Paulo Brazil, with 16 attending nurses as participants. Results: 90 hours of observation were performed, of which 58% (52 hours and 10 minutes) were related to indirect care activities of the patients. The most frequent activities/interventions were: "Communication" - 1,852 (44.1%), mean 34.6 (SD = 54); "Walking" - 1,023 (24.3%), mean 22 (SD = 49.2); and "Documentation" - 663 (15.8%), mean 82.7 (SD = 144.4). Conclusion: These findings favor a redesign of the work process and foster the need to update and refine the current workload measurement instruments.

Abstract The founding of Akademgorodok near Novosibirsk in the late 1950s features prominently in the historiography of the Thaw and the general turn of Soviet science to the eastern parts of the country. This article puts this story into the context of the formation of modern “green” ideas in the late Soviet Union and reconsiders the relationship between humans and nature, along with the definition of nature itself. Akademgorodok produced a telling visual perspective: the architectural plan for the city dictated that its scientific, industrial, and living zones were drowned deep in the taiga. Architects named this type of urban planning “diffusive,” and memoirists described it as a “Forest City.” Using the term of Sheila Jasanoff, we designate this “Forest City” as a sociotechnical imaginary of Akademgorodok. Our aim is to study the historical roots of the “Forest City” and how it became a collective imaginary. How did it happen that in the 1950s and 1960s, when the “faces” of Soviet cities were defined by districts of standard panel houses, that a city was built near Novosibirsk in which so much attention was given to pre-human flora, fauna, and landscapes? What ideas and intellectual contexts composed the concept of Akademgorodok as a “Forest City”? Our answer possesses two dimensions. First, the rejection of the use of decorative elements in housing construction in the post-Stalin epoch stimulated architects to pay more attention to the greening of cities. They revived the concept of a “garden city” proposed by Ebenezer Howard on a new level. Second, the evolution of the ideas of Mikhail Lavrentyev, the founder of Akademgorodok, who upon arrival in Siberia applied the productivist program manifested in the slogan “Siberia is a treasure of resources,” but later changed his opinion to more “green” views under the influence of the so-called “Baikal Discussion.” The viewpoints of Lavrentyev influenced the design of this “center” of Siberian science, and then he formulated the idea of a “Forest City.” These contexts enable the utopian horizons and the search for models of a constructed future that were typical of the Thaw era to reflect upon the important challenges of the contemporary Anthropocene.
