This article presents LifeReview, a model that aims to facilitate the therapeutic process and the interaction between patients and mental health professionals, helping them in the treatment of anxiety disorder. The model uses as a basis the records of dysfunctional thoughts, a tool widely used by cognitive-behavioral therapy, incorporating it into an application capable of collecting media data and the patient's location. Allied to this, a management panel allows the therapist to visualize and interact with the sent records, besides personalizing the patient's experience through tips and techniques for anxiety control. A prototype was developed following the model specifications and evaluated with specialists in the area through scenarios, denoting a potential treatment aid.

The Brazilian Public Software Portal (BPS Portal) is a software ecosystem promoted by the Brazilian Government in order to share public software projects among the different federal administration sectors and entities. Although collaboration in the development of Free/Libre/Open Source Software (FLOSS) projects is considered one of the decisive factors for its success, there are no studies on its level in the BPS Portal. In addition, there exist few recent studies on the current state of the ecosystem, primarily regarding possible changes of incentive by its promoter, the Federal Government. In this context, an exploratory study was carried out on the GitLab platform of the BPS Portal with two different views: one regarding the representation and historical analysis of its life cycle and its different phases; and another in relation to the level of collaboration within each public software. The results indicated that the BPS Portal would currently be in the final phase of its life cycle (termination). It was also possible to identify a higher level of collaboration in public software created during the amplification phase.

Currently, the widespread of fake news has raised on the political class and society members in general, increasing concerns about the potential of misinformation that can be propagated, appearing on the center of the debate about election results around the world. On the other hand, satirical news has an entertaining purpose and are mistakenly put on the same boat of objective fake news. In this work, we address the differences between objectivity and legitimacy of news documents, treating each article as having two conceptual classes: objective/satirical and legitimate/fake. Thus, we propose a Decision Support System (DSS) based on a text mining pipeline and a set of novel textual features that uses multi-label methods for classifying news articles on those two domains. For validating the approach, a set of multi-label methods was evaluated with a combination of different base classifiers and then compared to a multi-class approach. Results reported our DSS as proper (0.80 F1-score) in addressing the scenario of misleading news from challenging perspective of multi-label modeling, outperforming the multi-class methods (0.71 F1-score) over a real-life news dataset collected from several portals of news.

Information Systems support business, people and government, and e-Government (SGE), Social Information Systems (SIS) or Social Systems (SS) are examples of such systems. A complex sociotechnical network is formed around SGE/SIS/SS and each element is an actor of influence. Challenges emerge with the relationships between the actors and the particularities of each region. Investigating the sociotechnical nature of these types of systems is relevant to the analysis and understanding of the technological development that occur over the years in each scenario. Based on this motivation, the objective of this research is to identify sociotechnical elements of SGE/SIS/SS through a systematic mapping study. As a contribution, this study identifies a set of sociotechnical elements relevant to these systems and points out the need for sociotechnical studies towards the development of different regions, especially in Brazil.

Applications developed with JavaScript language are increasing every day, not only for client-side, but also for server-side and for mobile devices. In this context, the existence of tools to identify faults is fundamental in order to assist developers during the evolution of their applications. Different tools and approaches have been proposed over the years, however they have limitations to evolve over time, becoming obsolete quickly. The reason for this is the use of a fixed list of pre-defined faults that are searched in the code. The BugAID tool implements a semiautomatic strategy for discovering bug patterns by grouping the changes made during the project development. The objective of this work is to contribute to the BugAID tool, extending this tool with improvements in the extraction of characteristics to be used by the clustering algorithm. The extended module of the BugAID extraction module (BE) that extracts the characteristics is called BE+. Additionally, an evaluation of the clustering algorithms used for discovering fault patterns in JavaScript software is performed. The results show that the DBScan and Optics algorithms with BE+ presented the best results for the Rand, Jaccard and Adjusted Rand indexes, while HDBScan with BE and BE+ presented the worst result.

Attention Deficit Hyperactivity Disorder has been one of the most studied topics in school-age children in face of their day-life difficulties. At the same time, gamification, which uses game mechanics in a non-game context, is an used strategy to engage people in reaching their goals in different contexts. Thus, this paper aims to present software guidelines for the design of gamified educational technologies to patients with this deficit. The requirements were compiled based on the results of a study conducted with parents, psycho-pedagogues, psychologists and speech therapists. Two main guideline categories were found: (i) behavioral strategies and (ii) gamification elements used, the first being composed of 17 strategies and the second by 12 gamification elements. From these categories and data analysis, 16 system requirements were proposed for the development of gamified applications to people with Attention Deficit Hyperactivity Disorder.

Smart Contracts are software code that resides within a blockchain, using its infrastructure as an advantage and guarantee of execution. Blockchain and smart contracts are enabling new business models and standards to information systems. However, a smart contract needs to be well tested before to be published in a blockchain, since it cannot be changed after being deployed. The execution time to deploy smart contracts and run their tests is considerable because all transactions must be mined before being added to a new block. This work proposes an approach to reuse the execution of the deployment and the setup of unit test in smart contracts to reduce the execution time of these tests. Experiments have shown a large reduction in the execution time of smart contract unit tests, without breaking the principle of test independency.

The performance of Software Engineering professionals is related, among other factors, to adequate knowledge management practices. Specifically, business vision modeling, requirements, and use-case extraction are central elements in Software Engineering, since they reflect the needs, specificities and functionalities to be considered at the software development stage. All these activities are related to knowledge acquisition and modeling. The goal of this work is to implement an educational process based on knowledge acquisition that assists in more dynamic and active pedagogical practices. This process was tested with software engineering students. The results showed advantages in the adoption of a strategy using principles of knowledge acquisition and modeling. It is possible to conclude that the introduction of the process in the classroom improves students' performance in business vision modeling and in the extraction of use cases and requirements.
