By using ICT in an innovative way, governments can improve the delivery of services and interaction with stakeholders. Open data is a way to help public organizations became more open and improve ...interaction with stakeholders. This paper aims to identify what are the public values enhancements acquired on smart city environment that discloses open data. We propose a conceptual model to analyze the smart city initiative. We contextualized the model taking a smart city domain by analyzing three related-initiatives that comprises open data in a smart city case carried at Rio de Janeiro Operations Center (COR) in Brazil by seven deep-interviewees directly involved - from inside and outside – in this case. The findings reveal evidences that open data initiatives contribute to enhance the delivery of public value in smart city contexts.
A clear-eyed, critical examination of the social, political, and economic costs of hosting the 2016 summer Olympics The selection of Rio de Janeiro as the site of the summer 2016 Olympic Games set ...off jubilant celebrations in Brazil—and created enormous expectations for economic development and the advancement of Brazil as a major player on the world stage. Although the games were held without major incident, the economic, environmental, political, and social outcomes for Brazil ranged from disappointing to devastating. Rio 2016 assembles the views of leading experts on Brazil and the Olympics into a clear-eyed assessment of the impact of the games on Brazil in general and on the lives of Cariocas, as Rio's residents are known. Edited by sports economist Andrew Zimbalist, the other contributors include Juliana Barbassa, Jules Boykoff, Jamil Chade, Stephen Essex, Renata Latuf, and Theresa Williamson.
This study proposes a comprehensive methodology to the application of an Artificial Neural Network Ensemble (ANNE) for the mapping of landslide susceptibility. The identification of susceptible areas ...was performed on the basis of landslide inventory databases and seven parameters from three classes: geomorphological (elevation, aspect, slope, topographic moisture index, profile curvature),geological (lithology) and environmental (land use). Studies are presented for two major cities in Brazil, Porto Alegre and Rio de Janeiro. As the main result, we show that the susceptibility maps generated by the ANNE feature higher accuracy than those published by official organs such as the Brazilian Geological Survey and Geotechnical Institute Foundation (Geo-Rio). This indicates that the proposed methodology can be an effective tool to assist the development of reliable landslide susceptibility maps in an efficient and agile manner.
•A throughout methodology to the generation of landslide susceptibility maps is presented.•Artificial Neural Network Ensembles are applied as the backbone of the methodology.•Two relevant case studies demonstrate the effectiveness of the proposed methodology.•Comparisons with maps published by official agencies attest the quality of the results.

ABSTRACT The Land of Brazil and travel literature: Vespucci and Quatro Navegações or Lettera a Soderini. False attribution of the discovery of Rio de Janeiro to Gaspar de Lemos and André Gonçalves. Foundation of “Feitoria do Rio de Janeiro”, called “Feitoria de Cabo Frio”. The stay of the Magellan fleet in Guanabara and the priority of the toponym “Rio de Janeiro”. João Lopes de Carvalho and his son Joãozinho “Niñito” at the Guanabara Bay factory. More and political utopia on an island in Rio de Janeiro.

Reading Rio de Janeiro blazes a new trail for understanding the cultural history of 19th-century Brazil. To bring the social fabric of Rio de Janeiro alive, Zephyr Frank flips the historian's usual ...interest in literature as a source of evidence and, instead, uses the historical context to understand literature. By focusing on the theme of social integration through the novels of José de Alencar, Machado de Assis, and Aluisio Azevedo, the author draws the reader's attention to the way characters are caught between conflicting moral imperatives as they encounter the newly mobile, capitalist, urban society, so different from the slave-based plantations of the past. Some characters grow and triumph in this setting; others are defeated by it. Though literature infuses this social history of 19th-century Rio, it is replete with maps, graphs, non-fiction sources, and statistical data and analysis that are the historian's stock-in-trade. By connecting a literary understanding of the social problems with the quantitative data traditional historical methods provide, Frank creates a richer and deeper understanding of society in 19th-century Rio.
Objetivou-se neste trabalho, investigar o comportamento do emprego formal no setor petrolífero do estado do Rio de Janeiro no período de 2005 a 2019, que foi dividido em dois subperíodos: 2005 a 2014 ...e 2014 a 2019. Utilizou-se como modelo analítico o método diferencial-estrutural (método shift-share). Os resultados mostraram, no primeiro subperíodo, que o setor de petróleo é extremamente importante na geração de empregos nos municípios produtores de petróleo, onde se destacam Macaé e Rio das Ostras. Nestes municípios, o emprego no setor de petróleo cresceu a uma taxa bem acima da média estadual. No segundo subperíodo, verificou-se que o desemprego no setor de petróleo e no Estado como um todo apresentou forte crescimento. De acordo com o método shift-share, em todos os municípios considerados, a atividade petrolífera perdeu dinamismo.
Background: This study focuses on urban arboviruses, specifically dengue (DENV), chikungunya (CHIKV), and Zika (ZIKV), which pose a significant public health challenge in Rio de Janeiro state, ...Southeast Brazil. In our research, we highlight critical findings on the transmission dynamics of these arboviruses in Rio de Janeiro, identifying distinct patterns of disease spread. Methods: By combining genomic data with case reports from the Brazilian Ministry of Health, we have analysed the phylogenetics, prevalence and spatial distribution of these endemic viruses within the state. Findings: Our results revealed sustained DENV transmission primarily in the northern part of the state, a significant ZIKV epidemic in 2016 affecting all mesoregions, and two major CHIKV outbreaks in 2018 and 2019, predominantly impacting the northern and southern areas. Our analysis suggests an inverse relationship between arboviral case incidence and urban density, with less populous regions experiencing higher transmission rates, potentially attributed to a complex interplay of factors such as the efficacy of vector control measures, environmental conditions, local immunity levels, and human mobility. Furthermore, our investigation unveiled distinct age and gender trends among affected individuals. Notably, dengue cases were predominantly observed in young adults aged 32, while chikungunya cases were more prevalent among individuals over 41. In contrast, cases of ZIKV were concentrated around the 33-year age group. Intriguingly, females accounted for nearly 60% of the cases, suggesting a potential gender-based difference in infection rates. Interpretation: Our findings underscore the complexity of arbovirus transmission and the need for interventions tailored to different geographical mesoregions. Enhanced surveillance and genomic sequencing will be essential for a deeper, more nuanced understanding of regional arbovirus dynamics. Identifying potential blind spots within the state will be pivotal for developing and implementing more effective public health strategies, specifically designed to address the unique challenges posed by these viruses throughout the state.
