This paper investigates the state of the practice of ASD estimation based on User Stories. We conducted a survey with 85 Brazilian professionals experienced in ASD estimating. The survey analyzes what is used in the estimation (User Story, task, or both), its differences, how the estimate is made (especially if there is any segmentation), and the average precision of the effort estimates. The main findings are: 1) Planning Poker is the most used technique and points with a Fibonacci scale as a metric; 2) User Stories are broken down into tasks in the vast majority of teams; 3) Teams that estimate both: User Stories and tasks/subtasks showed greater accuracy compared to the others; 4)At least ¼ of the teams make estimates for the team segmenting by some criteria.

This research aims at providing a guiding support for the selection of relevant features and quality requirements for designing persuasive software systems. To do this, a mapping between the Persuasive System Design (PSD) model and a generic Sustainability-Quality (SQ) model was carried out. As a result of this mapping, we extended the SQ model, by adding certain types of relationships with specific features of the PSD model. A Graph database tool, named Neo4j, was used for facilitating the visualization of the identified relationships. And we also used the query language Cypher in order to retrieve data from the graph. Finally, we used an existing persuasive software system for illustrating the usefulness of the extended SQ model represented as graphs.

Although Blockchain has grown in importance, great barriers still remain, including high failure rates, governance concerns and issues with quality attributes. These barriers have complex interactions and many trade-offs which suggests the need for design tools such as reference governance models and reference architectures. However, these tools are scarce and research in this area, especially governance, is sparse. The object of this research is thus to propose and then validate a new reference governance model and reference architecture to better design systems with desired attributes. The research will be conducted using the design science methodology and validated through case studies.

Hoy en día, uno de los desafíos tecnológicos es el desarrollo de software para sistemas de IoT, ya que operan en escenarios altamente cambiantes, siendo complejo con las metodologías de Ingeniería de Software tradicionales identificar todos los requisitos del sistema en la etapa de desarrollo. Una alternativa es incrementar su autonomía, dotándoles de capacidades de autoconsciencia con el apoyo de los modelos en tiempo de ejecución, a fin de trasladar varias de las funcionalidades que se programan durante el desarrollo al tiempo de ejecución. Este trabajo doctoral propone desarrollar una metodología basada en modelos en tiempo de ejecución para la construcción y operación de sistemas autoconscientes de IoT.

Several languages have been developed for writing smart contracts for specific domains, such as health, finance, and business processes. However, none of them includes the constructors needed for writing smart contracts used in application integration processes which have their own particularities. Such smart contracts are responsible for monitoring the communication between the process and the applications to guarantee that the rights of the parties involved in the integration process are observed. To cover the gap, this paper discusses a domain-specific language for writing smart contracts in the application integration domain. It provides constructors to write smart contracts with a level of abstraction close to the natural language used in conventional contracts.

Refactoring is a fundamental practice in modern software development. Therefore, it is essential that practitioners have a solid understanding of refactoring, both in theory and in practice. In this paper, we rely on a graph-based abstraction — called refactoring graphs — to visualize and analyze refactorings performed by students in a canonical refactoring application: the Video Store System, proposed by Fowler. We asked 46 students to perform the refactorings included in this example under two scenarios: according to a list of explicit guidelines, where most students performed the tasks successfully; and by using flexible ones, in which a part of the students faced problems identifying the appropriate operations. We conclude by presenting discussions and implications.

The aspects of mobile technology have introduced challenges for developers, raising the need to improve the software development methodologies traditionally used. As a result of the analysis of the state of the art, an agile methodological approach for its development is presented, consisting of 8 phases: negotiation, planning, design, implementation and alpha testing, beta testing and feedback analysis, application publication, release and maintenance, promotion, and a series of steps, good practices, principles and tools, to offer mechanisms to accompany and streamline the development process. Some validations were carried out including a exploratory study, seeking to propose a robust methodology but at the same time easy to apply in a company.

Software projects are common inputs in Empirical Software Engineering (ESE), and they are often selected without following a specific strategy, leading to biased samples. To avoid this problem, researchers choose to use publicly available datasets instead of picking the projects themselves. However, some datasets are not maintained, containing old versions of projects, or even deprecated ones. This may raise some representativeness issues due to major changes in development practices and technologies over time. The main goal of this research is to develop a procedures model to construct and maintain a software project dataset with their product quality metrics, to support the development of ESE studies.

Continuous Experimentation (CE) has become increasingly popular across industry and academic communities. Given its rapid evolution in software engineering (SE), the lack of a common understanding of CE can jeopardize new implementations and justify research efforts. Therefore, this literature study characterizes CE in SE based on its definitions, processes, and strategies for experimentation available in the technical literature. Seventy-six sources of information provided many different definitions, processes, and experimental procedures used to describe CE in SE. Despite the increasing use of CE in SE, it is impossible to observe a common terminology yet to support its characterization and use.

Muchas actividades de nuestra vida cotidiana se encuentran integradas a aplicaciones web, las cuales deben ser accesibles a todos los usuarios. Por esto resulta fundamental incorporar la accesibilidad al proceso de desarrollo. Para facilitar esta integración y la detección de problemas de accesibilidad, en este trabajo se desarrolló una herramienta automática para la detección y reporte de este tipo de problemas denominada ABF (Accessibility BadSmells Finder). La misma busca ayudar a los desarrolladores a proveer sitios web accesibles, gracias a que realiza búsquedas dinámicas de diversos problemas de accesibilidad y que no son detectados por otras herramientas debido a la complejidad de su detección.
