Publication . Sousa, Mafalda; Brandão, Catarina; Veloso, Ana; Gonçalves, Sónia; Silva, Isabel; Santos, Joana; Vieira dos Santos, Joana
Introdução/Enquadramento: A pandemia Covid-19 trouxe diversos desafios a nível económico e laboral, social e organizacional, tendo as organizações que adotar estratégias para garantir o seu funcionamento, mas também garantir e promover a saúde e bem-estar dos trabalhadores. Questão de Investigação/Objetivos: Este estudo teve como objetivo identificar e descrever: (1) o impacto da Covid-19 no mundo do trabalho, e (2) as estratégias que as organizações adotaram para minimizar esse impacto. Método: Foi realizado um estudo transversal qualitativo descritivo, onde foram recolhidos dados de 18 participantes (10 Gestores de Recursos Humanos, cinco especialistas de áreas relevantes sobre as vivências profissionais com a Covid-19 e três representantes de entidades públicas e da sociedade civil portuguesa nas áreas do trabalho e do género) através de entrevistas semiestruturadas. Os dados foram analisados à luz da análise de conteúdo categorial temática, com o apoio do NVivo®. Resultados: A pandemia teve impacto (QI1) a nível do trabalho, económico e laboral, da conciliação, e da saúde e bem-estar. As medidas (QI2) mais frequentemente implementadas pelas organizações foram ao nível da higiene e segurança no trabalho, adaptação ao teletrabalho, conciliação e comunicação. Considerações finais: Os dados apontam para um mundo do trabalho cada vez mais remoto e flexível, transformado pelo uso das novas tecnologias. No (re)desenho do trabalho é essencial ter em conta as características e necessidades de cada trabalhador.
CTCovid19: automatic Covid-19 model for computed tomography scans using deep learning
Publication . Antunes, Carlos; Rodrigues, Joao; Cunha, António
COVID-19 is an extremely contagious respiratory sickness instigated by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Common symptoms encompass fever, cough, fatigue, and breathing difficulties, often leading to hospitalization and fatalities in severe cases. CTCovid19 is a novel model tailored for COVID-19 detection, specifically honing in on a distinct deep learning structure, ResNet-50 trained with ImageNet serves as the foundational framework for our model. To enhance its capability to capture pertinent features related to COVID-19 patterns in Computed Tomography scans, the network underwent fine-tuning through layer adjustments and the addition of new ones. The model achieved accuracy rates that went from 97.0 % to 99.8 % across three widely recognized and documented datasets dedicated to COVID-19 detection.
Green banking awareness and its association with green attitude, green trust, and green loyalty
Publication . Rocha, Viviane; Viegas, Cristina; Martins Guerreiro, Maria Manuela; Viola, Thiago Wendt; Kluwe-Schiavon, Bruno
The lack of consumer awareness regarding Green Banking Practices (GBP) poses a challenge for banks aiming to benefit from them and for sustainable development. This paper developed a scale for exploring the Green Banking Awareness (GBA) among Brazilian highly educated consumers and its association with Green Attitude (GA), Green Trust (GT), and Green Loyalty (GL). 414 participants answered an online survey. Descriptive analyses, principal component analysis, and structural equation modelling approaches were used to verify the item's structure and the relationship between variables. Although the respondents agree that they are environmentally conscious, most did not recognize the GBP in their banks. We observed that GA did not significantly correlate with GL and GT, but GBA significantly correlated with GT and GL. Also, GA was associated with education. Our results might help the bank industry, the finance regulators, and governments to better understand GBA and act to increase it.
Characterization of knowledge, attitudes, comfort, and perception of discrimination regarding sexual and/or gender minoritized people: comparison between two cohorts of medical students - 2018–2023
Publication . Macedo, Ana; Ferreira, João; Gutierrez, Ana Rita; Gato, Jorge
Objectives: Despite progress made in the medical field to address the health concerns ofsexual and gender minoritized identities, LGBTQIAþ individuals continue to experience dis-crimination in healthcare. This study aims to evaluate the effects of incorporating a seminaron gender identity and sexual orientation into the medical curriculum of a PortugueseMedical School, after 5 years. The study’s main objective was to compare the changes in stu-dents’ knowledge, attitudes, comfort, and perception of discrimination against LGBTQIAþ,pre and post-intervention.Methods: A total of 313 students in their third, fourth, fifth, and sixth year at a PortugueseMedical School were assessed in 2018 (pre-intervention) and 2023 (post-intervention). Thedata collected were analyzed regarding age, gender identity, sexual orientation, number offriends or family members who identify themselves as LGBTQIAþ, and level of religiosity.Results: The overall knowledge regarding LGBTQIAþ people specific health aspects improvedfrom the 2018 cohort to the 2023 cohort, with significant differences in questions regardinggender identity (OR ¼ 2.0, p ¼ .007), sexual orientation (OR ¼ 2.9, p <.001), and mentalhealth (OR ¼ 3.2, p <.001). The perceived discrimination against homosexual patients wassimilar in both cohorts, with approximately 60% of respondents from both groups agreeingthat homosexual patients were discriminated against in healthcare.Conclusion: Although the perception of discrimination against LGBTQIAþ people in health-care remained high across the two cohorts, positive changes were observed regarding stu-dents’ overall knowledge of LGBTQIAþ individuals’ health, clinical preparation and comfortin treating LGBTQIAþ people, and attitudes toward lesbian women and gay men. Theseresults reinforce the need to develop training and information strategies targeting medicalstudents, promoting greater knowledge and, above all, increasing contact and clinical prac-tice with LGBTQIAþ people, since relationships and personal contact are the most differenti-ating aspects for nondiscrimination.
Mapping lateral stratigraphy at Palaeolithic surface sites: a case study from Dhofar, Oman
Publication . Rose, Jeffrey Ian; Hilbert, Yamandú H.; Usyk, Vitaly I.; Bebber, Michelle R.; Beshkani, Amir; Buchanan, Briggs; Cascalheira, João; Chlachula, Dominik; Dellmour, Rudolf; Eren, Metin I.; Garba, Roman; Hallinan, Emily; Li, Li; Walker, Robert S.; Marks, Anthony E.
Open-air accumulations of chipped stone debris are a common feature in arid landscapes, yet despite their prevalence, such archives are often dismissed as uninformative or unreliable. In the canyonlands of Dhofar, southern Oman, lithic surface scatters are nearly ubiquitous, including extensive, multi-component workshops associated with chert outcrops. These sites typically display chronologically diagnostic features that correspond to distinct taphonomic states, which in turn appear linked to spatial distribution, with more heavily weathered artifacts often found farther from the chert outcrops. We propose that post-depositional modifications and spatial distributions of chipped stone artifacts reflect site formation processes and, under certain conditions, may provide relative chronological information when absolute dating methods are unavailable. Our study tests this hypothesis by mapping artifact distribution and lithic taphonomy across a series of surface sites in southern Oman, spanning the Lower, Middle, and Upper/Late Palaeolithic periods. The results largely support our model, offering valuable insights into surface site formation and technological change over time. While these findings serve as broad predictive markers for age, their applicability for analyzing finer-scale assemblage variability remains to be determined. Future taphonomic recording systems should aim to quantify surface modifications to enhance replicability for such studies.
