The objective was to analyze the posts on Online Social Network Services by the Military Firefighters Corps related to covid-19, especially the informative character of the institution, to identify the relationship between posts and official documents.

As methodological procedures, the following actions were defined: collect data from the posts; analyze the data including the calculation of representativeness of posts supported by documents, most used services, and post periods; check classification terms, and perform the analysis of official documents. The sample was limited to the Military Fire Brigades of the states of Pará, Ceará, São Paulo, Santa Catarina, and Goiás on Facebook, Instagram, and Twitter.

The results show timeliness in the publication of content in these services in the early days. The publications were marked with terms of the theme and georeferencing. It was identified a low percentage of publications linked to official documents, 5.05% of the publications. Instagram stands out, with the greatest coverage, and the actions taken by the states of Goiás, Santa Catarina, and Pará.

Tags Analysis on the sale of fruits from the…

Social indexing is the ability to represent information made by the users of a system to share and retrieve information. In an Online Social Network Service (OSNS) it is possible to perceive the intrinsic aspects of social indexing through the use of tags in the marketing of products.

The goal is to analyze tags to characterize social indexing in Amazon fruit sale ads within an On-line Social Networking Service. The methodological procedures were carried out through an exploratory analysis of an experimental nature with direct participation; the data collection selected the ads that deal individually about each fruit on the Facebook Marketplace.

From the analysis of the data sets, it was possible to verify the aspects of the use of tags in ads in terms of quantity and frequency. The tags were classified based on the role each one plays concerning the resource indexed by the user. In addition, aspects regarding geographic location and content representation in the ad title were observed.

It was possible to identify the social indexing in the use of tags in the OSNS Facebook Marketplace when it comes to Amazonian fruits, as the tags are made up of semantic value and not just decontextualized textual fragments: they have intrinsic aspects that depend on the user or user groups, which they use to attribute an interpretation that may vary according to the context.

Pandemic, Family Farming and Information and Communication Technologies: research…

This editorial reflects on an event that marked the year 2020. The moment is of a pandemic, which brought up challenges already faced in history, but with an extra spice – the interrelation of People, Information and Communication Technologies (ICT). Perhaps this milestone has driven or even consolidated, a trend that has already been penetrating the social fabric since the “universalization” of digital devices and the Internet, called by Castells (1999) as the Information Society.

Archival Science and Blockchain: theoretical discussion about opportunities and…

Blockchain has characteristics that can contribute to archival activities related to the security of digital documents, although it was a technology created to solve problems of financial transactions. This research aims to identify the opportunities and barriers presented by Blockchain, especially to examine the challenges that this technology can bring to Archival Science.

This bibliographic research has a qualitative and quantitative approach, carried out through the analysis of scientific communications published in journals and conference proceedings available in Google Scholar, SciELO, and Web of Science knowledge bases. The data was collected during April and May 2019. Among the 108 publications collected, 57 were discarded because they did not meet the defined criteria. A total of 51 publications were analyzed, among which 12 were identified with topics related to the area of ​​knowledge studied. After applying the research quality criterion, 5 publications were selected to be analyzed.

About the opportunities offered by Blockchain, the integrity of digital documents and access to information are among the most addressed issues. On the other hand, the time lag to register information, technological obsolescence, and privacy issues are among the challenges to adopt Blockchain. It is concluded that Blockchain may is an important asset for Archival Science not only to ensure the authenticity of the documents but also to optimize and maintain security in the processing and storage of digital archival documents. However, it is paramount to discuss in more depth about long-term preservation, information privacy, and user privacy.
