Information and communication technologies (ICT) are increasingly permeating our daily life and we ever more commit our data to the cloud. Events like the COVID-19 pandemic put an exceptional burden upon ICT. This involves increasing implementation and use of data centers, which increased energy use and environmental impact. The scope of this work is to summarize the present situation on data centers as to environmental impact and opportunities for improvement. First, we introduce the topic, presenting estimated energy use and emissions. Then, we review proposed strategies for energy efficiency and conservation in data centers. Energy uses pertain to power distribution, ICT, and non-ICT equipment (e.g., cooling). Existing and prospected strategies and initiatives in these sectors are identified. Among key elements are innovative cooling techniques, natural resources, automation, low-power electronics, and equipment with extended thermal limits. Research perspectives are identified and estimates of improvement opportunities are mentioned. Finally, we present an overview on existing metrics, regulatory framework, and bodies concerned.

The contemporary hybridism has led new generations to a connected-based society in which relations among individuals are even more mediated by the arising Information and Communication Technologies (ICT). Some aspects of these mediations need to be deeply understood since new and different usages, habits, and practices with media are being observed among those born since the nineties – the digital natives. Aiming to investigate this context, a study was carried out to better understand how children and teenagers interact with four screens: computers, TV, games, and mobile phones. From a quantitative methodological approach, data was collected using a survey applied in Brazilian schools. A theoretical framework on digital literacy concepts was used as base for two-layer of data analysis on these four media, and the results were organized in five topics that show the main outcomes. They can be the basis of further educational policies grounded in real diagnosis.

Information and communication technologies (ICT) are increasingly permeating our daily life and we ever more commit our data to the cloud. Events like the COVID-19 pandemic put an exceptional burden upon ICT infrastructures. This involves increasing implementation and use of data centers, which increased energy use and environmental impact. The scope of this work is to take stock on data center impact, opportunities, and assessment. First, we estimate impact entity. Then, we review strategies for efficiency and energy conservation in data centers. Energy use pertain to power distribution, IT-equipment, and non-IT equipment (e.g. cooling): Existing and prospected strategies and initiatives in these sectors are identified.

Over the last decade, data journalism has evolved alongside information and communication technologies, spreading more and more into professional journalism. The purpose of this article is to understand if and how traditional press has reacted to the new technological tools available for reporting and the increasing availability of open data, whether public or private. To investigate these issues, articles published on the websites of three major Brazilian newspapers – Folha de S. Paulo, O Globo and O Estado de São Paulo – were analyzed for their coverage of International Women's Day in 2017. The results indicate that there is still a lack of data in most of the material, that the use of digital visualization techniques is still in its early stages and that there is no raw data supply in news production. On the other hand, the use of data and statistics without reference or source checking is quite noticeable and frequently occurs in the corpus.Na última década, o jornalismo de dados evoluiu ao lado das tecnologias de informação e comunicação, espraiando-se cada vez mais pelo ambiente do jornalismo profissional. A proposta deste artigo é compreender se e como o jornalismo impresso tradicional tem reagido às novas ferramentas tecnológicas disponíveis para a prática da reportagem e à crescente disponibilidade de dados abertos, sejam eles de origem pública ou privada. Para investigar estas questões, foram utilizadas como material de análise reportagens publicadas nos sites de três grandes jornais brasileiros – Folha de S. Paulo, O Globo e O Estado de São Paulo – durante a cobertura do Dia Internacional da Mulher em 2017. Os resultados indicam que a presença dos dados ainda ocorre na menor parte do material analisado, que o uso das técnicas digitais de visualização é incipiente e a oferta de dados brutos no processo de produção da notícia não existe. Por outro lado, foi possível perceber que o uso de dados e estatísticas sem indicação ou checagem de fontes é bastante frequente no corpus estudado.En la última década, el periodismo de datos creció al lado de las tecnologías de información y comunicación, tomando el campo del periodismo profesional.

Abstract While education is being increasingly permeated by Information and Communication Technologies (ICT), the current school is considered outdated and hardly capable of responding to the challenges of our time. Home Education emerges as a growing alternative, especially in developing countries, where it is not yet properly regulated and developed. This article presents a qualitative multiple case study focused on exploring the use of ICT by 70 Colombian families who educate at home. Data analysis was conducted following Grounded Theory’s steps from human, educational and technological dimensions. The results show that, within a context of constant social pressure, parents conceive ICT as mediators that allow them to access open support communities and resources, in order to develop their own guiding skills, enhance the development of their children’s talents, mainly through gaming, collaboration, research and outdoor exploration. This becomes a lifestyle that ends up changing their relationships and family dynamics.

The methods of measuring driving behaviour and the quality of drive in road transport are important factors in data acquisition and subsequent analysis of driving. The prevalence of smart terminal devices and cost effectiveness of On-Board Diagnostics (OBD) sensor devices provide great potential and the availability of the aforementioned technologies. This study shows the possibility of using information and communication technologies (ICT) and sensor devices for measuring the effectiveness of eco-driving. The ease of implementation of ICT elements, the accuracy of collected data and their storage for later data analysis offer a number of possibilities to use. This study shows the technical solution of the system and analysis of collected data on actual driving samples. By comparing normal and eco-driving modes, the advantage of using eco-driving modes is demonstrated through reduced fuel consumption and CO2 emissions amounting to almost 23% and 31%, respectively.
