Supporting the Careers of Developers with Disabilities: Lessons from Zup Innovation

People with still face discrimination, which creates significant obstacles to accessing higher education, ultimately hindering their access to high-skilled occupations. In this study we present Catalisa, an eight-month training camp (developed by Zup Innovation) that hires and trains people with disabilities as software developers. We interviewed 12 Catalisa participants to better understand their challenges and limitations regarding inclusion and accessibility. We offer four recommendations to improve inclusion and accessibility in Catalisa-like programs, that we hope could motive others to build a more inclusive and equitable workplace that benefits everyone.Comment: 5 pages (two columns), 1 figure

Nasopharyngeal carriage of Staphylococcus aureus among imprisoned males from Brazil without exposure to healthcare: risk factors and molecular characterization

Background: Previous studies report high prevalence of Methicillin-resistant Staphylococcus aureus (MRSA) colonization among imprisoned populations. However, there are no data on that prevalence in Brazilian correctional institutions.Findings: We tested 302 male prisoners for nasopharyngeal colonization with Staphylococcus aureus from February 2009 through April 2010. The overall isolation rate of S. aureus was 16.5% (50/302). Men who had sex with men, users of inhalatory drugs and those with previous lung or skin diseases were more likely to be colonized with S. aureus. MRSA was isolated from 0.7% of subjects (2/302). The two Community-associated (CA)-MRSA belonged to ST5 but were unrelated based on the PFGE results. Both harbored SCCmec IV, and did not possess the Panton-Valentine Leukocidin gene.Conclusion: We found low prevalence of S. aureus and CA-MRSA among prisoners. MRSA isolates ST5 from two subjects harboured SCCmec IV and presented different PFGE patterns

Understanding Self-Efficacy in the Context of Software Engineering: A Qualitative Study in the Industry

CONTEXT: Self-efficacy is a concept researched in various areas of knowledge that impacts various factors such as performance, satisfaction, and motivation. In Software Engineering, it has mainly been studied in the academic context, presenting results similar to other areas of knowledge. However, it is also important to understand its impact in the industrial context. OBJECTIVE: Therefore, this study aims to understand the impact on the software development context with a focus on understanding the behavioral signs of self-efficacy in software engineers and how self-efficacy can impact the work-day of software engineers. METHOD: A qualitative research was conducted using semi-structured questionnaires with 31 interviewees from a software development company located in Brazil. The interviewees participated in a Bootcamp and were later assigned to software development teams. Thematic analysis was used to analyze the data. RESULTS: In the perception of the interviewees, 21 signs were found that are related to people with high and low self-efficacy. These signs were divided into two dimensions: social and cognitive. Also, 18 situations were found that can lead to an increase or decrease of self-efficacy of software engineers. Finally, 12 factors were mentioned that can impact software development teams. CONCLUSION: This work evidences a set of behavioral signs that can help team leaders to better perceive the self-efficacy of their members. It also presents a set of situations that both leaders and individuals can use to improve their self-efficacy in the development context, and finally, factors that can be impacted by self-efficacy in the software development context are also presented. Finally, this work emphasizes the importance of understanding self-efficacy in the industrial context.Comment: 10 pages, 3 figure

Sobre o queer podemos pesquisar em currículo e educação?

Esse artigo pensa e discute as expansões, os obstáculos e as imaginações da teoria queer no presente para problematizar sobre o que podemos pesquisar em currículo e educação no Brasil. Consideramos que o queer, como analítica da normalização, seja uma ferramenta de que não podemos abrir mão para pensar os efeitos das normas nas vidas de muitas pessoas que demandam ainda mais expansões em territórios, sejam físicos e/ou conceituais; defendemos que há, ainda, obstáculos em pesquisar algumas temáticas queer desde a educação e o currículo, porque algumas áreas são legitimadas para tal; concordamos que há imaginações porvir que tensionem, ampliem e possam nos fazer pensar o mundo para além das normas e que se fabule a existência em seu sentido amplo

Portal blood flow volume measurement in schistosomal patients: evaluation of Doppler ultrasonography reproducibility

OBJECTIVE: To evaluate the reproducibility of Doppler ultrasonography in the measurement of portal blood flow volume in schistosomal patients. MATERIALS AND METHODOS: Prospective, transversal, observational and self-paired study evaluating 21 patients with hepatosplenic schistosomiasis submitted to Doppler ultrasonography performed by three independent observers for measurement of portal blood flow. Pairwise interobserver agreement was calculated by means of the intraclass correlation coefficient, paired t-test and Pearson's correlation coefficient. RESULTS: Interobserver agreement was excellent. Intraclass correlation ranged from 80.6% to 93.0% (IC at 95% [65.3% ; 95.8%]), with the Pearson's correlation coefficient ranging between 81.6% and 92.7% with no statistically significant interobserver difference regarding the mean portal blood flow volume measured by Doppler ultrasonography (p = 0.954 / 0.758 / 0.749). CONCLUSION: Doppler ultrasonography has demonstrated to be a reliable method for measuring the portal blood flow volume in patients with portal hypertension secondary to schistosomiasis, with a good interobserver agreement.OBJETIVO: Avaliar a reprodutibilidade do ultra-som Doppler na quantificação do volume de fluxo portal em pacientes esquistossomóticos. MATERIAIS E MÉTODOS: Estudo prospectivo, transversal, observacional e autopareado, avaliando 21 pacientes portadores de esquistossomose hepatoesplênica, submetidos a mensuração do fluxo portal pelo ultra-som Doppler por três observadores, de forma independente, sendo calculada a concordância entre estes, dois a dois, pelo coeficiente de correlação intraclasse, teste t-pareado e grau de linearidade de Pearson. RESULTADOS: A concordância interobservador foi excelente. O coeficiente de correlação intraclasse variou entre 80,6% e 93,0% (IC a 95% [65,3% ; 95,8%]), com coeficiente de correlação de Pearson variando entre 81,6% e 92,7% e sem diferença estatisticamente significante entre os observadores quanto à média do fluxo portal mensurado pelo ultra-som Doppler (p = 0,954 / 0,758 / 0,749). CONCLUSÃO: O ultra-som Doppler é um método confiável para quantificar o fluxo portal em pacientes portadores de hipertensão porta de origem esquistossomótica, apresentando boa concordância interobservador.Universidade Federal de São Paulo (UNIFESP) Escola Paulista de Medicina Departamento de Diagnóstico por ImagemUniversidade Federal de São Paulo (UNIFESP) Escola Paulista de MedicinaUNIFESP, EPM, Depto. de Diagnóstico por ImagemUNIFESP, EPMSciEL

Mixtures and Their Separation Methods: The Use of Didactic Games, the Jigsaw Method and Everyday Life as Facilitators to Construct Chemical Knowledge in High School

One of the difficulties found in Chemistry teaching, mainly in High School, is to establish relations among society, environment, science and technology. It is notorious and has required Chemistry teachers to have certain skills, including some that refer to several situations in everyday life. Therefore, this study aimed at introducing three methodological proposals to teach the content “methods of mixture separation”. The first proposal aimed at addressing concepts and procedures based on different situations found in everyday life. The second offered students some strategies to encourage them to form different points of view and opinions. It favored both intellectual autonomy and access to production of chemical knowledge collectively and collaboratively (the jigsaw method). The third was related to the use of didactic games to make learning easier. The use of games in Chemistry teaching is a methodology that has been used because it enables students to have pleasure and fun while learning. Four classes of freshmen (first year in High School) that attend the Instituto Federal do Triângulo Mineiro - Campus Uberlândia Centro (IFTM-UDICENTRO), located in Uberlândia, MG, Brazil, took part in this study. Results suggest that all methodologies under investigation are also efficient in online lessons. Teachers can use them all together or individually. In addition, the didactic game under study was adapted so that it could be played in online Chemistry lessons, since the world has still been affected by the infectious disease caused by the coronavirus. The adaptation of the game called “SeparaMix” has not been published in the literature yet). DOI:  http://dx.doi.org/10.17807/orbital.v13i5.165
