Ink Under the Fingernails: Making Print in Nineteenth-Century Mexico City

This dissertation examines Mexico City’s material politics of print—the central actors engaged in making print, their activities and relationships, and the legal, business, and social dimensions of production—across the nineteenth century. Inside urban printshops, a socially diverse group of men ranging from manual laborers to educated editors collaborated to make the printed items that fueled political debates and partisan struggles in the new republic. By investigating how print was produced, regulated, and consumed, this dissertation argues that printers shaped some of the most pressing conflicts that marked Mexico’s first formative century: over freedom of expression, the role of religion in government, and the emergence of liberalism. Printers shaped debates not only because they issued texts that fueled elite politics but precisely because they operated at the nexus where new liberal guarantees like freedom of the press and intellectual property intersected with politics and patronage, the regulatory efforts of the emerging state, and the harsh realities of a post-colonial economy.

Historians of Mexico have typically approached print as a vehicle for texts written by elites, which they argue contributed to the development of a national public sphere or print culture in spite of low literacy levels. By shifting the focus to print’s production, my work instead reveals that a range of urban residents—from prominent printshop owners to government ministers to street vendors—produced, engaged, and deployed printed items in contests unfolding in the urban environment. As print increasingly functioned as a political weapon in the decades after independence, print production itself became an arena in struggles over the emerging contours of politics and state formation, even as printing technologies remained relatively unchanged over time.

This work examines previously unexplored archival documents, including official correspondence, legal cases, business transactions, and printshop labor records, to shed new light on Mexico City printers’ interactions with the emerging national government, and reveal the degree to which heated ideological debates emerged intertwined with the most basic concerns over the tangible practices of print. By delving into the rich social and cultural world of printing—described by intellectuals and workers alike in memoirs, fiction, caricatures and periodicals— it also considers how printers’ particular status straddling elite and working worlds led them to challenge boundaries drawn by elites that separated manual and intellectual labors. Finally, this study engages the full range of printed documents made in Mexico City printshops not just as texts but also as objects with particular visual and material qualities whose uses and meanings were shaped not only by emergent republicanism but also by powerful colonial legacies that generated ambivalent attitudes towards print’s transformative power.

Colonialism, political unconscious and cognitive mapping in the space of the film "Captain Phillips"

The purpose of this article has been made through a Marxist analysis of the US film "Captain Phillips" (PaulGreengrass, 2013), based on a true story. I have found how the evolution of capitalism in the West continuesto consolidate the belief reified in a historical and geographical superiority of the political and socioeconomicwestern models regarding Africa and Asia lowers models. At the same time, through categories like dialecticalmaterialism, criticism of diffusionist theory and application of cognitive mapping to large geopoliticalspaces located in most poor areas of the world, I have realized a remark about currently being articulatingthe political unconscious of working class in rich countries and the poor in poor countries, establishing arelationship between the ideological representation that takes an individual from his historical reality (ona scale that moves from local to global), and how he has developed a mental ability to escape of the responsibilityto make a critical review of what's happening around him in all areas. Finally, through physicalspace captured in the film, I have realized a materialist critique of globalized business process that takesplace through the carriage of goods, outlining spatial and cognitively limits of the mentality of our time, bothamong "winners"as among the "losers", based on the spatial movement of capital.

Propuesta sostenible para mitigar los efectos climáticos adversos en una ciudad costera de Argentina

Los indicadores de sostenibilidad climática constituyen herramientas fundamentales para complementar las políticas de ordenamiento del territorio urbano y pueden beneficiar la calidad de vida sus habitantes. En el presente trabajo se diseñó un indicador climático urbano para la ciudad de Bahía Blanca considerando variables meteorológicas y análisis de la percepción social. El mismo permitió delimitar la ciudad en cuatro regiones bien diferenciadas entre sí. A partir de entonces, se realizó una propuesta sostenible para mitigar los efectos adversos del clima a partir de la aplicación del método DPSIR. Las mismas estuvieron destinadas a mejorar las condiciones de vida de la población. Los resultados permitieron considerar que una pronta implementación de la misma junto con una activa participación de los actores sociales y los tomadores de decisiones es necesaria para mejorar las condiciones actuales en la que se encuentra la ciudad. Con las medidas propuestas, la población local sabrá cómo actuar ante la ocurrencia de distintos eventos extremos, eventos de desconfort climático, etc. Al ser un método sencillo, la metodología aplicada en este estudio puede replicarse en otras ciudades del mundo con el objetivo de mejorar la calidad de vida de los habitantes.

AUTO-RUINS. Thinks about automobile into the contemporary landscape

The article analyses the evolution of the representation of the automobile inserted in the natural and urban environment in the Contemporary Art, from the appearance of the first cars in the beginning of the 20th century until the present day. The text compares the diverse attitudes and analysis of some representative artists who have used the image of the machine in general and the car in particular in their aesthetic discourse, using as a conductive thread the metaphor of the life cycle (birth, growth, feeding, reproduction and death). It deals with the discovery, the development and the coexistence between human and the automobile and its interpretation as a basic element of the artistic work. The text connects the image of the automobile located in the contemporary industrial landscape utilizing the artist references who have integrated the car in their work inside the natural or artificial environment characteristic of each moment. At the same time, the article goes deeply into the relationship of romantic ruin and natural landscape and the evolution of the industrial and architectural modern environment, through the work of the artists who has used the car as an inhabitant of the landscape.

Coimbra: cidade amiga das pessoas idosas?!

Introdução: Em Portugal, bem como nos restantes países mundiais, tem sido registado, em virtude de múltiplas transformações societárias, um aumento crescente do envelhecimento demográfico. Este novo cenário demográfico originou uma reflexão, por parte de organizações supranacionais, sobre as cidades na sua relação com os munícipes mais velhos. Desta reflexão surge o projeto Cidade Amiga das Pessoas Idosas que apresenta referenciais de avaliação das cidades para que estas possam adaptar as suas estruturas e serviços aos seus munícipes mais velhos. Beneficiando desta forma do potencial que as pessoas mais velhas representam para a humanidade. Objetivos: O presente estudo tem como objetivo central verificar se a cidade de Coimbra é uma cidade amiga das pessoas idosas. Metodologia: A pesquisa remete para um estudo qualitativo exploratório a partir dos procedimentos metodológicos que constam do Protocolo de Vancouver. O focus group decorreu em duas sessões. Participantes: Foram auscultados 16 pessoas, 15 (93,8%) do sexo feminino. A idade média situa-se nos 79,88 anos (dp= ± 10,658), são maioritariamente viúvos (7= 43,8 %) e 7 (43,8%) e têm como habilitações a 4ª classe. Autoclassificam-se maioritariamente na classe média baixa (7 =43,8). Resultados: Das oito categorias analisadas três categorias “espaços exteriores e edifícios”, “transportes” e “respeito e inclusão social” são avaliadas com aspetos positivos e negativos. O “suporte comunitário e serviços de saúde” é avaliado como positivo enquanto a “habitação”, “participação social” e “comunicação e informação” são avaliados como negativos. As sugestões efetuadas referem-se a um único tópico “espaços exteriores e edifícios”. Conclusões: Se partilharmos a tese que uma cidade amiga das pessoas idosas estimula o envelhecimento ativo porque otimiza as oportunidades de participação no ambiente urbano melhorando, desta forma, a qualidade de vida das pessoas envelhecem. Os resultados que obtivemos, a partir da auscultação de um grupo de idosos, permitem-nos afirmar que Coimbra precisa de se adaptar aos seus munícipes mais velhos. Só assim Coimbra se poderá tornar uma cidade amiga das pessoas idosas. Importa igualmente registar que os resultados encontrados devem ser mediados pelo perfil sociodemográfico dos idosos entrevistados. / Introduction: In Portugal, as well as in other countries worldwide, has been registered by virtue of multiple associated transformations, an increasing growing of population. This new demographic scenario triggered, led to a reflection on the part of supranational organizations, about the cities in their relationship with the older residents. This reflection comes with the project Friendly City of Older Persons that presents benchmarks for the evaluation of cities so that they can adapt their structures and services to its older citizens. Enjoying this way the potential that older people represent for humanity. Objectives: This study aims to check if the city of Coimbra is an elderly friendly city. Methodology: The research refers to an exploratory qualitative study from the methodological procedures of the Vancouver Protocol. The focus group was held in two sessions. Participants: 16 people were sounded out, 15(93.8%) were female. The average ages tends at79.88 years (dp = ±10,658), are mostly widowers (7=43.8%) and 7 (43.8%) have the qualifications to4th grade. They are classified mostly in the lower middle class(7=43.8). Results: Of the eight analyzed categories three categories" outdoor spaces and buildings", "transport" and "respect and social inclusion" are evaluated on positive and negative aspects. The "community support and health services" is evaluated as positive as the"housing", "social participation "and "communication and information" are evaluated as negative. The suggestions are related to a single topic "buildings and outdoor areas." Conclusions: If we share the view that an elderly friendly citizen courages active aging because it optimizes the opportunities for participation in the urban environment improving, in this manner, the quality of life of the elderly. The results we obtained from the consultation of a group of elderly allow us to say that Coimbra needs to adapt to its older citizens. Only then Coimbra can become a friendly city of the elderly. It should also be noted that the results should be mediated by socio-demographic profile of elderly respondents.

Urbaania energiaa. Suvilahden, Hanasaaren A- ja Vuosaaren voimalaitokset osana helsinkiläistä kaupunkiympäristöä

Tutkimus koostuu kolmen Helsingissä sijaitsevan, kolmena eri aikakautena, 1910-, 1950- ja 1990-luvuilla, rakennetun voimalaitoksen arkkitehtuurista ja rakennustyypistä sekä niiden eroista ja erityisyyksistä samoin kuin näiden voimalaitosten roolista ja vaikutuksesta Helsingin kaupunkisuunnitteluun ja -rakentamiseen, kaupunkikuvaan sekä ympäristöestetiikkaan. Tutkimus on rajattu koskemaan erityyppisten voimalaitosten osalta yksinomaan kolmea helsinkiläistä kaupungissa sijaitsevaa voimalaitosta, Suvilahtea, Hanasaari-A:ta ja Vuosaaren A- ja B-laitoksia. Tutkimuksen tarkoituksena on ensinnäkin selvittää sekä periaatteessa että edellä mainittujen kolmen esimerkkikohteen kautta seikkoja, jotka ovat vaikuttaneet kunkin voimalaitoksen arkkitehtuuriin ja rakennustyyppiin kunakin aikakautena. Kaupunkivoimalan olennaiset elementit ovat korkea savupiippu, mittava polttoainevarasto sekä massiiviset rakennusmassat, jotka vaativat runsasta maankäyttöä. Toiseksi tutkimuksessa paneudutaan kaupunkisuunnitteluun laitoksen sijoittumisen osalta sekä ajallisesti että paikallisesti. Kolmanneksi selvitetään kaupunkikuvallisia ja ympäristöesteettisiä seikkoja, sekä niiden vaikutusten kehitystä voimalaitoksen toteutuksen ja nykyhetken kesken. Tutkimuksessa haetaan vastausta kysymykseen, miten Helsingissä sijaitseva voimalaitos arkkitehtuuriltaan, rakennustyypiltään ja sijoitukseltaan on soveltunut ja jatkossa soveltuu kaupunkisuunnittelun kannalta kaupunkikuvallisesti sekä ympäristöesteettisesti kyseiseen kaupunkiympäristöön. Tutkimus selvittää myös sitä ilmeistä ristiriitaa, joka syntyy kaupungin kehittyessä ja laajentuessa, jolloin voimalaitos infrastruktuurinsa ja useimmiten suunnattoman kokonsa vuoksi edustaa pysyvyyttä rakentuvan alueen sisällä. Tässä yhteydessä tutkimuksessa pohditaan esimerkkikohteiden avulla voimalaitoksen säilyttämistä puoltavia rakennustaiteellisia arvoja, mahdollista korvattavuutta, ja siinä yhteydessä haetaan vastauksia jäljelle jäävälle laitosrakennukselle kaupunkisuunnittelun kannalta asetettavista uusiokäytön vaatimuksista ja mahdollisuuksista. Tutkimuksen metodologia on sekä kvantitatiivisesti että kvalitatiivisesti historiallinen, esimerkkikohteita käsiteltäessä tarvittavassa määrin myös mikrohistoriallinen.

De repente, tudo mudou de lugar: refletindo sobre metamorfose urbana e gentrificação em Mossoró-RN

This study aims at solidifying the theoretical bases to provide, above all, an explanation for this phenomenon which currently happens, with a scenario of social, political, economic and cultural transformations worldwide in medium cities. Nevertheless, because it has different dimensions from its transformation axes, gentrification comes with change, but also with the introduction of a new purpose in the space using and occupation, outlining in this context the identity of places from the formation of centralities with the presence of flows with social and economic dynamicsThe current forms of geographic space appropriation show the directions of the senses and ideological profile which recreates the meanings and uses of content and materials from descriptions of a historical past. However, today there is an economic context in the urban space which refers to a search of strategies for change, i.e., the acquisition of parameter aimed at meeting the demands of the relationship between capital and labor, which ends up overriding some actions for the specification of the transformation methods within the urban space to be explained by new needs and also by the agents from the value adding to their interests and investments. Thus, we assume that the appreciation/gentrification of urban spaces may or may not result from the building of a public space, since the dialogic structure as a place of political interaction externalize conflicts and disagreements in general; it keeps segregating spaces. As new spaces are transformed, the access to them tends to happen with particular restriction, whereas some places like parks, shopping malls, high-rise and horizontal condos are the scene for major professional and family events. In this context, the gentrification process is used to designate interventions in the urban environment, in certain city spaces which are considered central to public and private investments. A historical place is permitted to be presented as a scenario, a stage full of attractions, through the transformation process. Studying gentrification consists of an analysis of the underlying interests in the transformation of these areas, and especially of the assessment of the interest level in the private sector to partner in order to modify the landscape. Gentrification results from the transformation processes of capital, which influences the efforts and investments application in order to establish and achieve optimal economic growth, focusing on a location socio-culturally centered in the urban space. Thus, the urban social structure develops in the light of some questions that relate not only the cities growth but also environmental conditions it provides in cities like Mossoro, State of Rio Grande do Norte, Brazil 2005 a 2011.

Foresterie urbaine : recensement mondial des publications, situation actuelle et besoins de recherche des municipalités canadiennes

L’arbre en ville offre plusieurs bienfaits, et ce, même s’il est souvent confronté à des conditions de vie difficiles. Au cours des années, la foresterie urbaine a suscité plusieurs travaux de recherches. Ce projet visait à faire un recensement des publications scientifiques de recherche en foresterie urbaine, à faire l’état de la situation des municipalités en matière de foresterie urbaine et à identifier les besoins de recherche en foresterie urbaine des municipalités canadiennes de 5 000 habitants et plus. Le premier objectif a été réalisé en utilisant plusieurs bases de données d’articles scientifiques et des mots clefs en foresterie urbaine. Un sondage pancanadien a permis de réaliser les deux autres objectifs. Le recensement que nous avons effectué des publications en foresterie urbaine depuis 1800 a montré, comme pour les publications scientifiques en général, mais de façon encore plus marquée, un accroissement de leur nombre ces dernières années. Ce recensement a aussi permis de révéler que les préoccupations de recherche touchent surtout l’effet des arbres sur la santé humaine et la qualité de l’air. L’identification des besoins de recherche réalisée auprès des responsables des espaces verts a permis de constater qu’il y avait toujours place pour la recherche dans ce domaine. Les municipalités veulent connaître, entre autres, quelles espèces d’arbres sont adaptées à l’environnement urbain, quel est l’effet des arbres sur le ruissellement des eaux de pluie et sur la santé humaine. Nous avons aussi constaté qu’il y avait un manque de transfert de connaissances entre les chercheurs et les responsables d’espaces verts ou que les recherches menées ne répondent pas aux besoins exprimés par les répondants. Le présent mémoire a permis de mieux cerner les besoins de recherche des municipalités canadiennes et permettra aux chercheurs de mieux définir les priorités de recherche en foresterie urbaine.

Contributo e caracterização de PM da ressuspensão rodoviária

Nos últimos anos, tem-se assistido a um crescimento no interesse do estudo da ressuspensão de pó de estrada, dado o reconhecimento da importância que esta fração representa para os níveis de partículas atmosféricas em ambiente urbano. Dada a prematuridade deste tema e, de forma a compreender e conhecer a sua contribuição e caracterização, realizou-se um estudo sobre a ressuspensão de pó de estrada urbano para as cidades do Porto e Braga. No âmbito do projeto AIRUSE e URBE, realizaram-se amostragens de PM10 no terreno com um dispositivo de amostragem móvel e em ambiente laboratorial com uma câmara de ressuspensão, sendo posteriormente analisado o seu conteúdo carbonoso por um sistema de análise termo-ótico de transmitância e, os elementos por ICP-MS e ICP-AES. Da campanha in situ resultaram cargas de PM10 compreendidas entre 0.190 e 49.5 mg.m-2 para a cidade do Porto e 0.577 mg.m-2 para o túnel rodoviário em Braga. As amostras caracterizam-se por serem dominadas pelos elementos Al, Fe, K, e Ca e conterem enriquecimentos de Sb, Fe, Cu, Sn e Zn, fruto da contaminação antropogénica da atividade rodoviária. No que respeita às amostragens em laboratório, utilizou-se uma câmara de ressuspensão e o dispositivo móvel aplicado na campanha anteriormente descrita para estudar e caracterizar a fração PM10 do pó de estrada urbano proveniente do Túnel Avenida da Liberdade (Braga). Os resultados obtidos para as duas metodologias foram de um modo geral similares, com o carbono total a representar cerca de 6% da massa total de PM10. Esta última é composta maioritariamente por Al, Fe, Ca e K, elementos característicos da crosta terrestre. Quanto ao fatores de enriquecimento calculados, denotou-se a presença de Sb, Zn, Cu e Sn, tendo-se associando ao desgaste dos travões e pneus.

An examination of the role of sound in defining the city in the context of Edinburgh

The surfeit of generic and place-specific sounds that exist in the urban environment contribute to what has been referred to as the soundscape. Within the built environment sound has the potential to create thresholds and acoustic territories that define and colour the experience and social functioning of inhabited spaces. In this research, a robust critical examination of the literature by prominent sound artists and theorists is used to illustrate how sound contributes to the urban experience. This is reinforced by primary research undertaken in the city of Edinburgh where the analysis and synthesis of these secondary sources is tested using bespoke soundworks to determine the ways in which sound contributes to our perception, reading and understanding of our physical environment. This research concludes by illustrating the potential for the future, technological development of the soundscape.

Distribuição dos metais nas poeiras colhidas em Estarreja: estudo da mobilidade e impacto potencial dos metais no ambiente

As poeiras urbanas, vulgarmente designadas na literatura por street dusts ou road dusts, são misturas heterogêneas de partículas minerais do solo e partículas resultantes do tráfego, formando um material com características únicas e específicas de cada local. Estas partículas, geralmente enriquecidas com elementos potencialmente tóxicos, quando inaladas ou ingeridas poderão ser um risco para a saúde das populações. Neste trabalho foram recolhidas 21 amostras de poeiras urbanas na cidade de Estarreja assim como amostras representativas de partículas relacionados com o tráfego (poeiras resultante do desgaste dos travões e das marcações dos pavimentos e estradas) com o objetivo de investigar a contribuição relativa destas partículas no comportamento geoquímico dessas amostras e o risco associado para as populações locais. Para a concretização do objetivo proposto caracterizou-se química e mineralogicamente as amostras de poeiras urbanas e as partículas relacionadas com o tráfego e avaliou-se a disponibilidade e bioacessibilidade para três elementos considerados potencialmente tóxicos (Cu, Pb e Zn) usando uma combinação de ensaios: (a) digestão ácida; (b) extração sequencial para identificar o fracionamento do Cu, Pb e Zn nas diferentes fases-suporte dos metais, e (c) bioaccessibilidade oral in vitro. Os resultados da análise química mostram que as poeiras dos travões apresentam concentrações elevadas em Fe, Cu, Zn, Mn, Ba, Sb, Cr e Ni sendo de referir diferenças composicionais significativas entre as amostras estudadas. A amostra de tinta contém teores elevados de Ba, Ca, Ti e Pb e também pode conter outros elementos tais como Co, Cr, Cu, Mn. Mineralogicamente constata-se que as amostras de poeiras dos travões tem uma composição mineralógica semelhante mostrando que são constituídas por uma elevada percentagem de material de baixa cristalinidade, grafite e óxidos/hidróxidos de Fe amorfos. A amostra de tinta de marcação dos pavimentos das estradas é composta por material mais cristalino do que a poeira dos travões e é essencialmente constituída por carbonatos (maioritariamente dolomite) e também por barite (em menor quantidade). Os resultados obtidos nas amostras de poeiras urbanas indicam a existência de associações de elementos que definem claramente a componente geogénica e/ou antropogénica e apontam para diferenças entre essas associações nas duas frações estudadas (250 m e 63 m). A heterogeneidade das poeiras é revelada pela existência de partículas com origem geogénica (por exemplo quartzo e aluminossilicatos), de partículas com características marcadamente antropogénicas (partículas enriquecidas em Fe, Pb, Zn e Cu) ou ainda de partículas com origem mista (óxidos de Fe e Ti). Os resultados da extração química seletiva sequencial permitiu concluir que, nas amostras em estudo, as fases de troca e ácido-solúveis são as fases suporte mais importantes para o Cu, Pb e Zn Os resultados dos ensaios de bioacessibilidade mostraram também que uma percentagem significativa de Cu, Pb e Zn total está disponível para absorção gástrica. Este estudo destaca também a necessidade de se caracterizar em detalhe as propriedades intrínsecas das partículas antrópicas presentes nas poeiras urbanas, de forma a compreender as variações da fração bioacessível nos diferentes elementos estudados assim como nas diferentes frações.

Ribeira, técnica versus natureza: transformações em prol de um projeto de modernização (1860-1932)

The necessity of the insertion of the capital of Rio Grande do Norte in the world-wide commercial scene and its claim as the seat of political power, in ends of nineteenth and beginning of twentieth century, determined the direction of urban interventions undertaken by government to restructure the city. In that matter, there were several actions of improvements and embellishment in Natal, which had, as a starting point, the adequacy works of the port, located in the Ribeira quarter, with the aim of ending the physical isolation that reinforced its economic stagnation. Besides the problems faced in the opening bar of the Potengi River, and would complement the required improvements, other barriers demonstrate the tension established between the physic-geographic field and the man: the flooded and slope which connected Cidade Alta and Ribeira the first two quarters of the city.The execution of these works demanded knowledge whose domain and application it was for engineering. But, how the actions done for the engineers, in sense to transform natural areas into constructed spaces made possible the intentional conformation of the quarter of the Ribeira in a commercial and politician-administrative center, in the middle of the XIX century and beginning of the XX? Understand, therefore, the employment effects of technology on the physical-geographical Ribeira, is the objective of this work that uses theoretical and methodological procedures of Urban Environmental History, by analyzing the relationship between the environment and the man, mediated by knowledge and use of technologies. The documental research was used, as primary sources, the Messages of the Provincial Assembly Government that later became the Legislative Assembly of Rio Grande do Norte reports and articles on specialized publications, in addition to local newspapers. The work is structured in five chapters. First, some comments about Urban Environmental History (Chapter 1) supplemented with analysis of the conceptual construction of nature in the Contemporary Era and its application in the city (chapter 02), the following chapters (03 and 04) deal with the rise of engineers as a active group in the Brazilian government frameworks and their vision about the nature inside the urban environment and it is studied how the professional technicians dealt with the improvement work of the harbor and in the shock with the natural forces. Other works that would complement this "project" of modernization and had had natural obstacles to be removed the Ribeira flood and slope constitute the subject of the fifth chapter. Finally, some final considerations retake the initial discussions aiming an association between the technique and the nature as junction elements inside the process of constitution of a Modern Natal

Caminhos que estruturam cidades: redes técnicas de transporte sobre trilhos e a conformação intra-urbana de Natal

The railroad, from 1870 and on, becomes an usual complaining in the press s and politician elite s speeches, especially because of Natal s geographic isolation. The implantation of two railroads in the capital territory Estrada de Ferro de Natal a Nova Cruz, afterwards part of Great Western Railway Company network, and Estrada de Ferro Central do Rio Grande do Norte had serious implications in the urban environment. While railroad s structures were already consolidated, other transportation mechanisms were being implanted in the first decades of the 20th century, such as trams lines, which, by the way, was a transport modal that also used rails as a dislocation meaning. Considering these questions, we may ask: how come railroads and tramways demands, roads and buildings had influenced the internal organization of Natal? We work with the general hypothesis that the influence of technical networks, composed by tramways and railroads, over Natal s urban space happened in a diversified way, sometimes consolidating social aspects in certain areas, sometimes improving the occupation of others. The impact over the city s territory also happens in a diversified way between the buildings/railroad s complexes and the pathways. The different scale of the train in comparison to the trams velocity, size, noise level, flow, among others is also a cause to the different consequences in urban environment. The main objective of this work is to understand the role of circulation technical networks in the construction process of urban space in Natal, as a way to contribute to the urban historiography about the subject. The time frame adopted, between 1881 and 1937, marks the time path of railroads and tramways in Rio Grande do Norte: 1881 is the year of railroad s first section inauguration from Natal to São José do Mipibu as well of the railroad complex in the Republic Square in Natal; the year of 1937 marks the beginning of tramways declination process in the city. At this time railroads and tramways had to face more intensively the competition of motor vehicles. The theory reference adopted is based on concepts and analysis of authors, such as Flávio Villaça and Roberto Lobato Corrêa references to the concepts of urban structure , localization and accessibility and Gabriel Dupuy to explain the concept of urban technical networks . These references reveal the conflict of different realities in the urban universe interests and values which is an important factor about the construction of urban space. The information sources used were from two distinctive natures: primary, journals of the time studied and official government reports, and secondary, based on other works about the subject. It was also used by this study iconographic source, especially images from the data base of the research group História da Cidade, do Território e do Urbanismo .

Mapeamento acústico como ferramenta para predição de ruído urbano na área de influência do estádio Arena das Dunas, Natal/ RN

The Noise Pollution causes degradation in the quality of the environment and presents itself as one of the most common environmental problems in the big cities. An Urban environment present scenario and their complex acoustic study need to consider the contribution of various noise sources. Accordingly to computational models through mapping and prediction of acoustic scene become important, because they enable the realization of calculations, analyzes and reports, allowing the interpretation of satisfactory results. The study neighborhood is the neighborhood of Lagoa Nova, a central area of the city of Natal, which will undergo major changes in urban space due to urban mobility projects planned for the area around the stadium and the consequent changes of urban form and traffic. Thus, this study aims to evaluate the noise impact caused by road and morphological changes around the stadium Arena das Dunas in the neighborhood of Lagoa Nova, through on-site measurements and mapping using the computational model SoundPLAN year 2012 and the scenario evolution acoustic for the year 2017. For this analysis was the construction of the first acoustic mapping based on current diagnostic acoustic neighborhood, physical mapping, classified vehicle count and measurement of sound pressure level, and to build the prediction of noise were observed for the area study the modifications provided for traffic, urban form and mobility work. In this study, it is concluded that the sound pressure levels of the year in 2012 and 2017 extrapolate current legislation. For the prediction of noise were numerous changes in the acoustic scene, in which the works of urban mobility provided will improve traffic flow, thus reduce the sound pressure level where interventions are expected
