- Diálogo entre culturas: a Cultura Indígena como resposta à dominação cultural na interlocução entre Enrique Dussel e Paulo FreirePublication . Alves, Deisiane; Cancian, Queli; Mesquita, ElzaNeste artigo analisamos o entrelaçamento entre cultura e educação, considerando os aspectos históricos que se relacionam a ambas no contexto brasileiro, desde os processos colonizadores, cujos elementos permearam a formação da identidade nacional. Processos estes que invisibilizaram a Cultura Indígena, seus saberes e tradições, elementos aqui destacados, como forma de contar uma outra história. Para tanto, nos embasamos na revisão bibliográfica, a partir da interlocução entre Enrique Dussel e Paulo Freire, ícones dos estudos pós-coloniais e decoloniais, que enfatizaram ao longo de toda sua trajetória, a dominação cultural exercida pelos processos colonizadores e a necessária identificação e libertação desta.
- Exploring the Influence of Social Media on Tourist Decision-Making: Insights from Cape VerdePublication . Martins, Wilson Semedo; Martins, Márcio Ribeiro; Morais, Elisabete PauloThis study explores the influence of social media on tourists’ decision-making processes, focusing on Cape Verde as an emerging tourist destination. The aim is to understand how social media platforms shape tourists’ perceptions and choices and how demographic factors like age and education affect the selection of information sources. A survey was conducted with 259 individuals intending to visit Cape Verde, employing a non-probability convenience sampling method. Data were analysed using chi-square tests to examine associations between age groups, education levels, and the use of social media and information sources. The results reveal significant associations between age and social media platform preference, with older tourists (44–79 years) favouring Facebook and younger tourists (18–29 years) preferring Instagram and TikTok. Additionally, education level influences the choice of information sources; higher-educated individuals are more likely to use social media and conduct independent research, while those with lower education levels tend to rely more on travel agencies and tourism fairs. These findings highlight the importance of tailored marketing strategies that account for demographic differences, offering practical insights for destination marketing organizations (DMOs) to better engage with diverse tourist segments.
- Occupational exposure to wildland firefighting and its effects on systemic DNA damagePublication . Esteves, Filipa; Madureira, Joana; Costa, Carla Sofia; Pires, Joana; Barros, Bela; Alves, Sara; Vaz, Josiana A.; Oliveira, Marta; Slezakova, Klara; Fernandes, Adília; Pereira, Maria do Carmo; Morais, Simone; Valdiglesias, Vanessa; Bonassi, Stefano; Teixeira, João Paulo; Costa, SolangePortugal is among the European Union countries more devastated by forest fires. Wildland fire- fighters are at the forefront of this battle, facing exposure to a wide range of harmful pollutants. Epidemiological studies have highlighted a potential link between occupational firefighting exposure and several diseases, including cancer. To date, very few studies have explored the biological mechanisms associated with such exposure. The present longitudinal study aims to assess changes in early effect biomarkers following wildland firefighters’ occupational exposure to a real wildfire event. Paired blood samples from 59 healthy Portuguese wildland firefighters were collected at two different time points: before wildfire season and after a fire event during wildfire season. Sociodemographic variables (e. g., age, sex) and work-related factors (e.g., years of service) were assessed via a self-reported questionnaire. Levels of early effect biomarkers, such as primary DNA damage and oxidative DNA damage (oxidised purines) were assessed via comet assay. DNA double-strand breaks (DSBs) were evaluated by phosphorylated H2AX (γH2AX). Moreover, hydroxylated polycyclic aromatic hydrocarbon metabolites (OHPAHs) and metal(loid)s were quantified in urine samples. The influence of urinary OHPAHs, urinary metal(loid)s, and other exposure- related factors (e.g., firefighting duration) on changes (Δ) in early effect biomarkers (post-vs. baseline levels) was investigated. Firefighting activities led to a significant increase in both primary DNA damage and oxidative DNA damage by 22 % (95 % CI: 1.11–1.35; p < 0.05) and 23 % (95 % CI: 1.04–1.45; p < 0.05), respectively. Results from linear regression revealed that per each unit increase of urinary 2-hydroxyfluorene (2-OHFlu) (μmol/mol creatinine), the risk of ⧍ oxidative DNA damage increased by 20 % [FR: 1.20 (1.09–1.32); p < 0.01]. Addi- tionally, each unit increase in urinary cesium (Cs) (μg/L) resulted in a significant 4 % increase in Δ primary DNA damage [FR: 1.04 (1.01–1.06); p < 0.05] and a 3 % increase in Δ oxidative DNA damage [FR: 1.03 (1.01–1.05); p < 0.05]. Post-exposure levels of γH2AX were significantly correlated with urinary 2-OHFlu levels assessed after firefighting (r = 0.30; p < 0.05). Furthermore, exposure duration and reported breathing difficulties during firefighting were significantly associated with increased levels of primary DNA damage. Results obtained provide insights into the potential human health effects of wildland firefighting occupational exposure at the genetic and molecular levels, offering new and important mechanistic data. These findings are crucial for implementing health and safety measures, recommendations, and best practices to mitigate occupational risks and protect the health of wildland firefighters.
