Smart City Governance: From E-Government to Smart Governance

Autores
Bernardo, MdRM;

Publicação
Smart Cities and Smart Spaces

Abstract
Smart governance is one of the characteristics of smart cities, having its roots in e-government, in the principles of good governance, and in the assumptions of citizens’ participation and involvement in public decision-making. This chapter aims to answer the question: “What smart governance practices are being implemented in smart cities” through an extensive literature review in the areas of e-government, good governance, smart cities and smart governance, and content analysis of the websites of seven smart cities: Amsterdam, Barcelona, Copenhagen, Lisbon, Manchester, Singapore, and Stockholm. The objective was to identify the presence of factors related with e-participation; e-services; and public administration functioning on the cities’ websites. The chapter ends with directions for future research and the conclusion that all the smart cities analyzed presented some factors related with smart governance, but with different levels of development and application. © 2025 Elsevier B.V., All rights reserved.

Alfabetización digital, lengua y literatura en la cibercultura: los ‘fanfics’ como recurso pedagógico

Autores
Lacerda, MM; Schlemmer, E;

Publicação
Revista de Educación de la Universidad de Granada

Abstract
Este estudio busca discutir y analizar, cualitativamente, la articulación de los fanfics como recurso didáctico para la enseñanza de lengua y literatura hispánica y sus implicaciones en el alfabetismo digital de los lectores. Se utiliza como marco teórico: Lemos (2009 e 2015), Alves (2015), Buzato (2004 and 2013), Coscarelli (2009), Vargas (2005), Neves (2014), Azzari & Custodio (2013), Almeida (2013), Almeida & Pais (2012), Cope & Kalantzis (2006) y Schlemmer (2010, 2013 y 2014). Se concluye que la enseñanza de lengua y literatura, en soporte digital, contribuye al alfabetismo digital; la escuela necesita apropiarse de nuevas actitudes para acompañar los cambios culturales en las prácticas sociales pertinentes a la inserción e inmersión de nuevas tecnologías, además de promover momentos de interacción, reflexión y discusión sobre literatura, lectura y autoría. Este género (fanfics), cuando se utiliza de forma dinámica, funciona como un objeto fronterizo entre dos mundos o mentalidades y además del más lleva al interior del aula la vivencia y práctica social de los jóvenes.

Letramento Digital na perspectiva emancipatória, digital e cidadã no desenvolvimento de práticas educativas gamificadas

Autores
Lacerda, MM; Schlemmer, E;

Publicação
Revista Diálogo Educacional

Abstract
O presente artigo é um recorte do projeto de pesquisa doutoral intitulado: “Letramento e emancipação digital cidadã: cartografias e rastros na constituição de Espaços de Convivência Híbridos e Multimodais”. Neste contexto, pretende-se discutir o letramento digital de estudantes da Educação Básica — na perspectiva emancipatória, digital e cidadã— no desenvolvimento de práticas educativas gamificadas, a partir da análise do jogo SM Real Life. A fundamentação teórica baseia-se em autores como: Latour (2012), Freire (2002), Schlemmer (2010, 2011), Schwartz (2007), Streck e Adams (2014) e Gee (2003). A pesquisa é qualitativa, exploratória e descritiva e fez uso do método cartográfico de pesquisa-intervenção (SCHLEMMER, 2015, 2018). Como instrumento de produção de dados, utilizou-se a observação participante, com registros, no diário de percurso, das pistas e dos rastros deixados pelos estudantes nos diferentes espaços de aprendizagem nos quais transitam. Conclui-se, a partir da análise dos rastros deixados pelos estudantes, que TD e práticas educativas gamificadas podem oportunizar inclusão, formação, empoderamento e emancipação digital e cidadã dos sujeitos, uma vez que eles utilizam e se apropriam efetivamente do poder transformador e emancipatório das TD; além disso, tais práticas oportunizam a criação de novas situações e espaços de aprendizagem.

Cooperative Key Generation For Data Dissemination in Cyber-Physical Systems

Abstract
Securing wireless communication is significant for privacy and confidentiality of sensing data in Cyber-Physical Systems (CPS). However, due to broadcast nature of radio channels, disseminating sensory data is vulnerable to eavesdropping and message modification. Generating secret keys by extracting the shared randomness in a wireless fading channel is a promising way to improve the communication security. In this poster, we present a novel secret key generation protocol for securing real-time data dissemination in CPS, where the sensor nodes cooperatively generate a shared key by estimating the quantized fading channel randomness. A 2-hop wireless sensor network testbed is built and preliminary experimental results show that the quantization intervals and distance between the nodes lead to a secret bit mismatch.

Abstract
Cooperative Cyber-Physical Systems (Co-CPSs) can be enabled using wireless communication technologies, which in principle should address reliability and safety challenges. Safety for Co-CPS enabled by wireless communication technologies is a crucial aspect and requires new dedicated design approaches. In this paper, we provide an overview of five Co-CPS use cases, as introduced in our SafeCOP EU project, and analyze their safety design requirements. Next, we provide a comprehensive analysis of the main existing wireless communication technologies giving details about the protocols developed within particular standardization bodies. We also investigate to what extent they address the non-functional requirements in terms of safety, security and real time, in the different application domains of each use case. Finally, we discuss general recommendations about the use of different wireless communication technologies showing their potentials in the selected real-world use cases. The discussion is provided under consideration in the 5G standardization process within 3GPP, whose current efforts are inline to current gaps in wireless communications protocols for Co-CPSs including many future use cases.

IEEE 802.15.4e in a Nutshell: Survey and Performance Evaluation

IEEE COMMUNICATIONS SURVEYS AND TUTORIALS

Abstract
The advancements in information and communication technology in the past decades have been converging into a new communication paradigm in which everything is expected to be interconnected. The Internet of Things, more than a buzzword, is becoming a reality, and is finding its way into the industrial domain, enabling what is now dubbed as the Industry 4.0. Among several standards that help in enabling Industry 4.0, the IEEE 802.15.4e standard addresses requirements such as increased robustness and reliability. Although the standard seems promising, the technology is still immature and rather unproven. Also, there has been no thorough survey of the standard with emphasis on the understanding of the performance improvement in regards to the legacy protocol IEEE 802.15.4. In this survey, we aim at filling this gap by carrying out a performance analysis and thorough discussions of the main features and enhancements of IEEE 802.15.4e. We also provide a literature survey concerning the already proposed add-ons and available tools. We believe this work will help to identify the merits of IEEE 802.15.4e and to contribute towards a faster adoption of this technology as a supporting communication infrastructure for future industrial scenarios.
