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

A influência das avaliações de fornecedores na rescisão de contratos de serviços de exploração e produção de petróleo e gás no Brasil

The supplier performance assessment literature shows that the prior identification of contracts considered unsatisfactory may prove crucial to the maintenance of a company, especially in sectors with high operational and environmental risk and significant investments, such as the oil and gas exploitation sector. Although considered important, contract termination has been little studied in the Brazilian oil segment, due to the small number of firms operating in the sector and restricted access to information from these companies. This article aims to reduce this gap by analyzing what service assessment criteria most influence contract terminations in the Brazilian sector of oil and gas exploitation and production. Therefore, the assessments of service contracts terminated between 1/1/2006 and 12/31/2014 by a business unit active in oil and gas exploitation and production located in Brazil were analyzed using logit regressions. In the resulting database, 273 contracts were found that include all specialized services in the activity, totaling 19,613 ratings. The results indicate that the Term and Logistics criteria reveal the greatest influence on contract cancelations of the sector activities. In addition, by segregating the analysis by specialty, it was found that different specialties have different requirements and therefore different contractual arrangements. These results empirically corroborate the theoretical discussions in the literature about the importance of compliance with contractual obligations, especially with regard to the negotiated deadlines.A literatura de avaliação de desempenho de fornecedores aponta que a prévia identificação de contratos considerados insatisfatórios pode se revelar crucial para a manutenção de uma empresa, especialmente em setores com alto risco operacional, ambiental e com investimentos significativos, como é o caso do setor de exploração de petróleo e gás. Embora considerada importante, a rescisão contratual tem sido pouco estudada no segmento de petróleo brasileiro, em decorrência do baixo número de firmas que atuam no setor e da restrição de acessos às informações dessas empresas. O presente artigo tem como objetivo diminuir essa lacuna ao analisar quais critérios de avaliação de serviços mais influenciam as rescisões contratuais no setor brasileiro de exploração e produção de petróleo e gás. Para tanto, foram analisadas, via regressões logit, as avaliações dos contratos de serviços encerrados no período de 1/1/2006 a 31/12/2014 por uma unidade de negócio que atua na exploração e produção de petróleo e gás localizada no Brasil. No banco de dados resultante, constaram-se 273 contratos que contemplam todas as especialidades de serviços da atividade, com um total de 19.613 avaliações. Os resultados indicam que os critérios Prazo e Logística são os que apresentam maior influência nas rescisões contratuais das atividades do setor. Além disso, ao segregar-se as análises por especialidades, verificou-se que diferentes especialidades possuem demandas distintas e, por conseguinte, diferentes modelos contratuais. Tais resultados corroboram empiricamente as discussões teóricas presentes na literatura acerca da importância do cumprimento das obrigações contratuais, especialmente com relação aos prazos negociados

An Actionable Framework for Understanding and Improving Talent Retention as a Competitive Advantage in IT Organizations

In the rapidly evolving global business landscape, the demand for software has intensified competition among organizations, leading to challenges in retaining highly qualified IT members in software organizations. One of the problems faced by IT organizations is the retention of these strategic professionals, also known as talent. This work presents an actionable framework for Talent Retention (TR) used in IT organizations. It is based on our findings from interviews performed with 21 IT managers. The TR Framework is our main research outcome. Our framework encompasses a set of factors, contextual characteristics, barriers, strategies, and coping mechanisms. Our findings indicated that software engineers can be differentiated from other professional groups, and beyond competitive salaries, other elements for retaining talent in IT organizations should be considered, such as psychological safety, work-life balance, a positive work environment, innovative and challenging projects, and flexible work. A better understanding of factors could guide IT managers in improving talent management processes by addressing Software Engineering challenges, identifying important elements, and exploring strategies at the individual, team, and organizational levels.Comment: arXiv admin note: text overlap with arXiv:2205.06352 by other author

EVALUATION OF A MICROIMMUNODIFUSION ASSAY FOR THE DIAGNOSIS OF ENZOOTIC BOVINE LEUKOSIS

O presente trabalho foi realizado com o objetivo de avaliar uma micro-IDGA usando protocolo simples para obtenção do antígeno comparativamente a uma macro-IDGA. Foram utilizadas 450 amostras de soro bovino provenientes de 92 rebanhos de 23 municípios que compõem a bacia leiteira do estado do Maranhão. O antígeno usado na micro-IDGA foi obtido por diálise frente ao polietilenoglicol de sobrenadante de células FLK infectadas pelo VLEB. Na micro-IDGA utilizou-se 10µL de antígeno e soro controle positivo e 30 µl do soro teste; na macro-IDGA 25 µl de todos os reagentes. Dos soros comparados, 57.56% (n=259) e 54.44% (n=245) apresentaram animais reagentes na micro-IDGA e macro-IDGA, respectivamente. Houve ótima concordância entre as duas técnicas (K=0,91), com sensibilidade e especificidade da macro-IDGA em relação à micro-IDGA de 93.43% e 98.43%, respectivamente. A micro-IDGA apresentou linhas mais claras que as observadas na macro-IDGA e a leitura pode ser feita 24 horas antes da macro-IDGA. Conclui-se que a micro-IDGA pode substituir à macro-IDGA no diagnóstico sorológico da LEB, com a vantagem de maior rapidez na emissão dos resultados e da obtenção do antígeno com técnica simples.  This work was developed to evaluate how a micro-AGID using simple protocol for obtaining the antigen compared to a macro-AGID. A total of 450 serum samples from 92 herds in 23 counties that make up the dairy herd of Maranhão were used. The antigen used in micro-AGID was obtained by desalting of supernatant of FLK cells infected with BLV against the polyethylenoglicol. In micro-AGID 10µL of antigen and positive serum control was used and 30 µl of test serum, in the macro-AGID 25 µl of all reagents were used. Of the compared sera, 57.56% (n=259) and 54.44% (n=245) showed positive animals reagents results in micro-AGID and macro-AGID, respectively. There was a very good agreement between both techniques (K=0.91), with sensitivity and specificity of the macro-AGID for micro-AGID of 93.43% and 98.43% with an accuracy of 95.96%. Micro-AGID showed clearer lines than those observed in the macro-AGID and reading can be made 24 hours before the macro-AGID. It is concluded that micro-AGID can be used successfully in the serological diagnosis of EBL, with the advantage of greater speed in issuing the results and obtaining the antigen with a simple technique

Promoting the use of low-cost solar water heater for Alta Paulista rural and low-income urban area

Solar heaters are an appropriate technology for tropical and subtropical climate to warm bath water through the energy from the sunlight. The development of conventional solar heaters is in the market and its acceptance is still low due to high cost. However, low-cost solar heaters have been developed in recent years for the care of a potential consumer demand, which in addition to using a renewable energy provides significant reductions in energy consumption. Environmental issue has highlighted towards current world problems. Our project proposal is to promote the construction of solar water heater based on the technique developed in Santa Catarina by José Alcino Alano, 2004 NGO Super Ecology prize winner, sponsored by Super Interessante magazine. They are built by using recyclable materials such as PET bottles and long life milk cartons reducing costs and using "junk" in order to produce thermal energy. This equipment has been patented with the intention that there would be exploited by companies for profit, and its design is of public domain. The objective of this study is to analyze the profile of potential users of solar water heaters at low cost. Thus, lectures and practical activities for rural and local low-income communities were performed in order to show how to build effective heating systems with recyclable materials and install them in the houses and show its economic feasibility as well as thermal comfort afforded and benefits to environment generated by the system, providing a free guide to building the system.</p

Análise comparativa in vitro entre o laser e gel de clorexidina na descontaminação de escovas dentais

As escovas dentais são usualmente armazenadas em banheiros e recebem uma grande carga de contaminação. &nbsp;Métodos físicos e químicos tem sido utilizados para sanitização desses dispositivos de higiene oral. O objetivo da presente pesquisa foi avaliar o efeito do laser associado ao corante no processo de descontaminação de escovas dentais em comparação a um gel de clorexidina a 2%. Quarenta pacientes adultos, entre 20 e 55 anos, portadores de gengivite associada ao biofilme supragengival, realizaram escovação dental três vezes ao dia, durante uma semana, momento em que as escovas foram recolhidas para o processo laboratorial de descontaminação. As escovas dentais foram divididas de forma similar em quatro grupos: Controle – sem descontaminação; Laser – descontaminação com luz laser; Laser C – descontaminação com luz laser associado ao corante e CLG – descontaminação com gel de clorexidina a 2%. As mesmas foram imersas durante trinta segundos em tubos de ensaio contendo Brain Heart Infusion (BHI), os quais foram colocados na estufa a 37oC durante 24 horas para ocorrer o crescimento bacteriano. O grupo Laser C apresentou menor nível de turvação e sedimento (p&lt;0,05), porém foi inferior ao grupo CLG (p&lt;0,05). O Laser C reduziu significativamente a contaminação dos dispositivos de higiene bucal, porém o meio químico contendo gel de clorexidina a 2% foi o método mais eficaz de descontaminação
