    Testing is an indispensable part of software development. However, a career in software testing is reported to be unpopular among students in computer science and related areas. This can potentially create a shortage of testers in the software industry in the future. The question is, whether the perception that undergraduate students have about software testing is accurate and whether it differs from the experience reported by those who work in testing activities in the software development industry. This investigation demonstrates that a career in software testing is more exciting and rewarding, as reported by professionals working in the field, than students may believe. Therefore, in order to guarantee a workforce focused on software quality, the academy and the software industry need to work together to better inform students about software testing and its essential role in software development

    Charting a Path to Efficient Onboarding: The Role of Software Visualization

    Full text link
    Background. Within the software industry, it is commonly estimated that software professionals invest a substantial portion of their work hours in the process of understanding existing systems. In this context, an ineffective technical onboarding process, which introduces newcomers to software under development, can result in a prolonged period for them to absorb the necessary knowledge required to become productive in their roles. Goal. The present study aims to explore the familiarity of managers, leaders, and developers with software visualization tools and how these tools are employed to facilitate the technical onboarding of new team members. Method. To address the research problem, we built upon the insights gained through the literature and embraced a sequential exploratory approach. This approach incorporated quantitative and qualitative analyses of data collected from practitioners using questionnaires and semi-structured interviews. Findings. Our findings demonstrate a gap between the concept of software visualization and the practical use of onboarding tools and techniques. Overall, practitioners do not systematically incorporate software visualization tools into their technical onboarding processes due to a lack of conceptual understanding and awareness of their potential benefits. Conclusion. The software industry could benefit from standardized and evolving onboarding models, improved by incorporating software visualization techniques and tools to support program comprehension of newcomers in the software projects

    Seasonal Patterns of the Foraging Ecology of Myrmelachista arthuri Forel, 1903 (Formicidae: Formicinae)

    Temporal dynamics of foraging activity, diet and habitat are key to understanding the bioecology of ants. These patterns are poorly studied in many Neotropical species, such as those belonging to genus Myrmelachista. In the present work, we investigate the foraging behavior and diet of M. arthuri and describe aspects of their food-searching behavior. We recorded the dynamics of workers exiting and entering nests built in the stems of native Atlantic forest trees during the cold/dry and warm/wet seasons. Food items carried by workers were also counted and identified. Myrmelachista arthuri foraged throughout the day, but worker activity became more intense as temperature increased and moisture declined, regardless of the season, and especially in the afternoon. This species had a generalist diet: 92% of the food items were live or dead arthropods or their remains, and a small proportion consisted of plant materials, such as seeds. Arthropod fragments, mostly of M. arthuri workers, represented the largest proportion of the diet, followed by whole Collembola individuals. Food items did not vary between seasons, the number of items was higher in the cold/dry season. The results of this work contribute to the understanding of M. arthuri biology, especially related to foraging dynamics

    “Dungeons and troubles”: uma proposta de RPG educativo sobre genética para o Ensino Médio/ “Dungeons and Troubles”: a proposal for educational Role Playing Games about Genetics to High School

    Mesmo sendo uma ciência tão dinâmica, o ensino de biologia, na maioria das vezes se dá de forma passiva e reduzido aos conteúdos de livros. Em todo o tempo, são disponibilizadas notícias nas mais diversas formas de mídias acerca de genética, sequenciamento de genoma, DNA, dentre outras. Os alunos de ensino médio nem sempre estão preparados para entender esses conceitos, por não dominarem premissas dessa ciência. O objetivo desse trabalho foi desenvolver um jogo lúdico do tipo RPG, como ferramenta lúdica para consolidação de conhecimentos adquiridos previamente em sala de aula. O jogo utiliza o RPG de aventura como base para que os alunos possam consolidar o conhecimento adquirido em sala de aula. Os alunos são inseridos em uma estória onde ficam presos em uma caverna e precisam responder perguntas para liberar a saída. Jogos do tipo RPG de aventura pressupõe que os jogadores busquem diferentes caminhos, cavernas, dentro do jogo e respondam as perguntas corretamente até que o objetivo seja cumprido. Assim, este material configura-se como mais uma proposta de atividade lúdica que facilitará o ensino de conceitos importantes de genética

    Low occurrence of Hepatitis A virus in water samples from an urban area of Southern Brazil

    Hepatitis A virus (HAV), a member of Picornaviridae family, is the main causative agent of acute viral hepatitis in the world, mainly in developing countries. HAV may be present in contaminated water and food and its presence is often associated to a lesser extent with socioeconomic factors and environmental quality. The main goals in the present study were to standardize a cell culture combined to a polymerase chain reaction protocol for the detection and quantification of viral viability and analyze whether the virus could be found in water samples collected in four urban streams of Sinos River watershed. Virus recovery was assayed from known virus concentrations measured in experimentally contaminated raw and ultrapure water (MilliQ®). Recovery rates ranged from 270% in raw water to 15,000% in ultrapure water. In a second step, a qPCR coupled to a previous passage in cells, demonstrated more analytical sensitivity when compared to samples assayed without a previous passage in cell cultures. HAV genome was detected in only 1 of 84 samples analyzed, pointing to a very low occurrence of HAV in water samples in the studied region. These findings are remarkable, since no more than 5% of the domestic sewage in this area is treated pointing to a low occurrence of HAV in the population living nearby during the study period

    Considering the importance of software testing to the development of high quality and reliable software systems, this paper aims to investigate how can work-related factors influence the motivation of software testers. Method. We applied a questionnaire that was developed using a previous theory of motivation and satisfaction of software engineers to conduct a survey-based study to explore and understand how professional software testers perceive and value work-related factors that could influence their motivation at work. Results. With a sample of 80 software testers we observed that software testers are strongly motivated by variety of work, creative tasks, recognition for their work, and activities that allow them to acquire new knowledge, but in general the social impact of this activity has low influence on their motivation. Conclusion. This study discusses the difference of opinions among software testers, regarding work-related factors that could impact their motivation, which can be relevant for managers and leaders in software engineering practice

    The aim of this study was to translate into Portuguese and validate the Pharmacy Services Questionnaire (PSQ). The instrument includes 20 questions that measure user satisfaction with pharmacy services, and is organized according to two factors. It uses a Likert scale of answers from 1 (poor) to 5 (excellent). The PSQ-Brazil was applied to 137 diabetics from 31 to 89 years of age (60.6% women), clients of private pharmacies, mostly users of public health services (65.7%), with low education (67.9% elementary schooling or less), and who used an average of 4.3 medicines per person. Overall score in the sample was 3.6 (SD = 1.1 [95%CI 3.4-3.8]). After factor analysis, “pleasant exposure” and “treatment management” included 8 and 12 items, respectively, and were significantly correlated with each other (r = 0.92, p < 0.001) and with the overall score. The instrument obtained a Cronbach's alpha of 0.98 for the overall score. The pleasant exposure and treatment management variables showed alphas of 0.94 and 0.98. PSQBrazil shows adequate reliability and validity for use in the country
