VISÃO BASEADA EM RECURSOS – UMA ANÁLISE HISTÓRICA DAS PUBLICAÇÕES NOS PERIÓDICOS NA ÚLTIMA DÉCADA POR AUTORES BRASILEIROS

O artigo tem por objetivo fazer uma análise da produção referente ao tema visão baseada em recursos, por afiliados a instituições brasileiras no período de 2005 a 2014, fazendo uma análise da correlação de pesquisadores da área, assim como uma análise dos trabalhos publicados. Para o levantamento dos dados foi utilizado o banco de dados Scopus, a análise dos dados foi através de análise descritiva e elaboração gráfica com os softwares Nvivo 10 e Ucinet 6. No total foram encontrados vinte e dois documentos publicados no período com os termos chave “VBR” e “RBV”, somente a partir do ano de 2007. O trabalho apresenta dados relevantes para pesquisadores compreenderem quais autores pesquisam sobre o tema atualmente no Brasil, assim como periódicos que estão publicando sobre o assunto observando-se a sua evolução de publicaçõesno período. Sugere-se novas pesquisas em outros bancos de dados para um maior entendimento sobre o tema em periódicos não indexados ao banco de dados Scopus

Simulation framework for connected vehicles: a scoping review [version 2; peer review: 2 approved]

Background: V2V (Vehicle-to-Vehicle) is a booming research field with a diverse set of services and applications. Most researchers rely on vehicular simulation tools to model traffic and road conditions and evaluate the performance of network protocols. We conducted a scoping review to consider simulators that have been reported in the literature based on successful implementation of V2V systems, tutorials, documentation, examples, and/or discussion groups. Methods: Simulators that have limited information were not included. The selected simulators are described individually and compared based on their requirements and features, i.e., origin, traffic model, scalability, and traffic features. This scoping review was reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR). The review considered only research published in English (in journals and conference papers) completed after 2015. Further, three reviewers initiated the data extraction phase to retrieve information from the published papers. Results: Most simulators can simulate system behaviour by modelling the events according to pre-defined scenarios. However, the main challenge faced is integrating the three components to simulate a road environment in either microscopic, macroscopic or mesoscopic models. These components include mobility generators, VANET simulators and network simulators. These simulators require the integration and synchronisation of the transportation domain and the communication domain. Simulation modelling can be run using a different types of simulators that are cost-effective and scalable for evaluating the performance of V2V systems in urban environments. In addition, we also considered the ability of the vehicular simulation tools to support wireless sensors. Conclusions: The outcome of this study may reduce the time required for other researchers to work on other applications involving V2V systems and as a reference for the study and development of new traffic simulators

Kingdon’s Multiple Streams Approach: What Is the Empirical Impact of this Universal Theory?

While John Kingdon’s Multiple Streams Approach (MSA) remains a key reference point in thepublic policy literature, few have attempted to assess MSA holistically. To assess its broaderimpact and trends in usage, we combine in-depth analysis of representative studies, withcomprehensive coverage of MSA-inspired articles, to categorize its impact. We find that Kingdon’swork makes two separate contributions. First, it has contributed to the development of“evolutionary” policy theories such as punctuated equilibrium. Second, it has prompted a large,dedicated, and often empirical, literature. However, most MSA empirical applications only engagewith broader policy theory superficially. The two contributions are oddly independent of eachother. We argue that these trends in application are due largely to its intuitive appeal and low“barrier to entry.” Drawing on other policy approaches, we offer suggestions to improve the MSAinspired literature
