The analysis of traffic problems in large urban centers often requires the use of computational tools, which give the possibility to make a more detailed analysis of the issue, suggest solutions, predict behaviors and, above all, support efficient decision-making. Transport microsimulation software programs are a handy set of tools for this type of analysis. This research paper shows a case study where functions and limitations of Aimsun version 8.2.0, a commercial-like European software and Sumo version 1.3.1, a European open-source software, are presented. The input and output data are similar in both software and the interpretation of results is quite intuitive for both, as well. However, Aimsun's graphical interface interprets results more user-friendly, because Sumo is an open-access software presented as an effective alternative tool for transport modeling.

All face-to-face studies were affected by the COVID-19 pandemic, as they could not be run in person due to rules and guidance linked to social distancing which were in force during the outbreak. Finding and testing an available COVID-secure approach for both participants and researchers was important as was the need to continue conducting such studies during this critical time. At present, the extant literature indicates a clear gap in research that elucidates how to carry out a Q methodology study online, step by step. This paper describes an option for online Q methodology using an approach that simulates all of the steps performed in a face-to-face setting using an open-source software known as Easy-HtmlQ. Using a case study in telemedicine adoption as illustration, this paper also considers the perspective of both research participants and Q methodology researchers via semi-structured interviews. Using Easy-HtmlQ V1.1 in online Q methodology studies appears to be an affordable, practical and user-friendly solution. Some of the benefits associated with running Q methodology studies online were the decreased costs, enabling the recruitment of wider number of participants, providing a COVID-19-secure environment and offering convenience to both participants and researchers during the research process. The findings of this study may contribute to increasing the number of online Q methodology studies in the future, as it has succeeded in offering a feasible approach for Q methodology researchers.

O desenvolvimento de software é uma atividade intensive em esforço humano. Assim, a forma como os desenvolvedores encaram suas tarefas é de suam importância. Em um ambiente como o usual em projetos de FOSS (free/open source software) em que profissionais (desenvolvedores pagos) compartilham os esforços de desenvolvimento com voluntários, a moral da comunidade de desenvolvedores e usuários é fundamental. Neste artigo, apresentamos uma análise preliminary utilizando técnicas de análise de sentimentos realizada em um projeto de FOSS. Para isso, executamos a mineração da lista de endereços eletrônicos de um projeto e aplicamos as técnicas propostas aos participantes mais relevantes. Embora a aplicação seja limitada, no momento atual, experamos que essa experiência possa ser benéfica no future para determiner situações que possam afetar os desenvolvedores ou o projeto, tais como baixa produtividade, abandono do projeto ou bifurcação do projeto, entre outras.

In 2006 my university academic IT support group was approached by an academic colleague wanting to start a new journal, which would be available in electronic form only. There were restrictions imposed by the technical capabilities of the pool of authors, the requirements of the discipline, and — unsurprisingly — the lack of financial resources. The decision was made to implement a system using only open source software, and building largely from scratch, as the existing open source journal publishing systems at the time, although comprehensive and well-established, were seen as far too large and complex for the task. This paper is a case study describing the process and explaining the background to the decisions made. It attempts to draw some conclusions about the technical viability of creating a small-scale publishing system which attempted to retain XML throughout the workflow, and about the human factors which influenced the decisions.

Software Migration

This paper investigates the contribution of stakeholder collaboration during an open source software migration using a case study. The case study is based on the Presidential National Commission, a South African government department that migrated from proprietary software to open source software in 2007. The organization was one of the few that migrated to open source software as part of a South African government initiative. The case study consisted of semi-structured interviews with the participants involved in the migration. The interviews centered on the contribution of stakeholder collaboration during the software migration using a boundary critique. The results suggest that stakeholder collaboration can contribute to open source software migration. From a managerial perspective, business leaders must understand the value of stakeholder collaboration in open source software migration. Boundary critique can be an important tool for achieving broader collaboration of stakeholders.

This study examines the concept of an ecosystem as originated in the field of ecology and applied to open source software projects. Additionally, a framework for assessing the three dimensions of ecosystem health is defined and explained using examples from a specific open source ecosystem. The conceptual framework is explained in the context of a case study for a sponsored open source ecosystem. The framework and case study highlight a number of characteristics and aspects of these ecosystems which can be evaluated by existing and potential members to gauge the health and sustainability of open source projects and the products and services they produce.
