- Correlation between trace element concentrations in the blood of female hawksbill (Eretmochelys imbricata) and egg quality in nesting populations of São Tomé IslandPublication . Morão, Inês; Simões, Tiago; Busom Casado, Roger; Vieira, Sara; Ferreira-Airaud, Betânia; Caliani, Ilaria; Di Noi, Agata; Casini, Silvia; Fossi, Maria C.; Lemos, Marco F.L.; Novais, Sara C.Metals and metalloids can pose a significant threat to sea turtles, as these contaminants tend to accumulate in their bodies over time, due to their long lifespans and varied feeding habits. São Tomé and Príncipe's archipelago hosts the last remaining rookery for hawksbill sea turtles (Eretmochelys imbricata) in the region. The study aimed to determine the levels of metals and metalloids accumulated by this population and to investigate their possible genotoxicity in nesting females' blood as well as potential effects on their eggs in terms of morphometric characteristics and the quality of their lipidic reserves, essential for embryo development. Higher levels of Hg were found to be correlated with increased “lobed-shaped nuclei” in erythrocytic count, suggesting genotoxicity effects in this population. Higher levels of Se were correlated with thicker and heavier eggshells, while Pb levels were associated with the reduction of the egg's diameter. Metal contamination in females' blood significantly affected yolk polar fatty acids. Significant negative correlations were found between general metal contamination (PLI) and saturated fatty acids (SFA), while positive correlations were observed for essential omega-6 fatty acids (n6), mostly influenced by Cu, Fe, and Hg concentrations. This suggests that these omega-6 fatty acids are being synthesized from SFA, potentially indicating stress response by metal exposure. The present results point to some potential alterations in the normal embryonic development of these turtle eggs, influenced by metal contamination, which should raise some concerns about the future of this critically endangered species and call for additional conservation efforts in the region.
- UNIVERSOS PARALELOSPublication . Policarpo, DianaNuma seleção de projetos há sempre uma ligação que se estabelece entre eles. Falaremos hoje de quatro projetos que concretizei recentemente: Death Grip (2019), Nets of Hyphae (2021-22), Ciguatera (2022-25) e Mutual Benefits (2024). Estes são universos e interesses que, pelo menos para mim, se tocam e crescem uns para os outros. Eu trabalho de uma forma muito experimental. O meu trajeto começou com uma educação musical inicial que me levou a trabalhar o som e a instalá-lo. Comecei com esse tipo de instalações, embora o meu interesse de base seja a escultura (ainda hoje faço escultura). É uma grande paixão que tenho. Isso revela-se em diversos projetos recentes, onde voltei a esculpir à mão. Os projetos de que aqui falaremos têm em comum uma transversalidade de certos elementos que gosto de trabalhar, entre eles a espacialização sonora, o filme multicanal e o desenho que, conceptual e esteticamente, se cruzam na busca por coisas novas, tal como as colaborações, que fazem com que diferentes modos de fazer entrem em contacto, o que eu acho muito prazeroso. A minha prática é colaborativa.
- Tell Me What You’ve Done, and I’ll Predict What You’ll Do: The Role of Motivation and Past Behavior in Exercise AdherencePublication . Cid, Luis; Monteiro, Diogo; Bento, Teresa; Susano Jacinto, Miguel Ângelo; Pereira dos Santos de Sousa Vitorino, Anabela; Teixeira, Diogo S.; Duarte-Mendes, Pedro; Bastos, Vasco; Couto, NunoIntroduction: The main purpose of this study was to test a hierarchical model of motivation that integrates Achievement Goal Theory and Self-Determination Theory to explain and predict exercise adherence. Method: In total, 2180 exercisers (1020 female, 1160 male) aged between 18 and 60 years, from different gyms and health clubs, completed several scales validated in exercise settings, regarding perceived motivational climate, basic psychological need satisfaction, behavioral regulation, and exercise adherence. For the last measure, weekly computer access to a control system over a 6-month period before and after data collection was consulted. Results: Through structural equation models (SEM), it was verified that (1) task-involving climate positively predicted basic psychological needs. In turn, the satisfaction of these needs predicted autonomous motivation, which led to a positive prediction of adherence; (2) a small variation in exercise adherence was explained by the motivational model under analysis. Nevertheless, models significantly improved their analytical power when past adherence was inserted in the model increasing the explained variance in future behavior from 9.2% to 64%. Conclusions: In conclusion, autonomous motivation can predict people's exercise adherence, and past behavior increases that predictive effect. The present study brings scientific evidence to the popular saying "tell me what you've done and, and I'll predict what you'll do".
- Technology-mediated training programs for school health teams on special health care needs: a scoping reviewPublication . Pires, Maria do Céu Coelho Monteiro; Barbieri-Figueiredo, Maria do Céu Aguiar; Cardoso, Daniela Filipa Batista; Duque, Filipa Margarida; Tricas-Sauras, Maria Sandra; Prosen, Mirko; Menino, Eva Guilherme; Sousa, Paulino Artur Ferreira deObjective: To map technology-mediated training programs for school health teams thataddress special health needs in the school environment and to identify their characteristics.Method: The review followed the JBI methodology. Eight databases were searched forpublished and gray literature. Studies published in Portuguese, English or Spanish since2000 were included to capture emerging training programs. Results: Of the 1,106 studiesidentified, 29 were reviewed in full and eight were included in the final analysis. All studieswere carried out in the United States of America. Program topics included chronic healthconditions such as diabetes, asthma, procedures, as well as emergency situations, all aimed atschool nurses and based on a conceptual or pedagogical framework. The programs includedthematic modules of various lengths and offered online and hybrid training through variousdigital educational resources. Conclusions: Programs focused on chronic health conditionsand assessed professionals' knowledge, skill development, self-efficacy, and confidence; fewstudies provided a detailed exploration of the underlying pedagogical models and did notuse formative assessment.
- Mediating Role of Basic Psychological Needs in the Association Between Exercise Goal Content and Subjective Well-Being in Portuguese Older AdultsPublication . Couto, Nuno; Antunes, Raul; Bento, T.; Pereira dos Santos de Sousa Vitorino, Anabela; Monteiro, Diogo; Cid, LuisBackground: This study aimed to examine the association between different exercise goals and their impact on subjective well-being (SWB) variables, namely, positive affect (PA), negative affect (NA), and satisfaction with life (SWL), as well as to explore the mediating role of basic psychological needs (BPNs) in this relationship within a sample of Portuguese older adults. Objectives: The present study aimed to analyze the association between extrinsic and intrinsic motivation for exercise, basic psychological needs (BPNs), and subjective well-being (SWB) in older Portuguese people. Methods: The sample study constituted 298 individuals (233 females, 65 males), aged between 60 and 90 years (M = 68.43; SD = 6.48). Through model four of the Process macro for SPSS version 3.5, a simple mediation analysis was carried out. Results: The results show that BPNs mediated the relationship between goal content for exercise health management and positive affect (PA) and satisfaction with life (SWL); goal content for exercise skill development and PA; goal content for exercise image, PA, and SWL; and goal content for exercise social affiliation and PA. Conclusions: Thus, we can conclude that BPNs stand out as a relevant mediator in the relationship between goal content for exercise and SWB variables, which reinforces the importance of BPNs in SWB promotion in the older population.
- Effects of a Twelve-Week Complementary Sports Program to Athletics Training on Motor Competence in Children Aged 6 to 10 Years Old—A Study ProtocolPublication . Lopes, Nataniel; Susano Jacinto, Miguel Ângelo; Monteiro, Diogo; Matos, Rui; Ibáñez, Sérgio J.Motor competence (MC) is defined as a global term that describes a person’s ability to be proficient in a wide range of motor acts. Based on this principle, we have created a training program that aims to determine the effect of 12 weeks of enriched athletics sports training with complementary motor activities on MC in children aged between 6 and 10 years old. The subjects will be divided into two groups: (i) the athletics training group (IG_A) that will participate in athletics training three times a week for 12 weeks, with 60 min sessions; and (ii) the athletics training + other activities group (IG_B) that will participate in athletics training twice a week and will have another activity training (gymnastics, handball, swimming, and motor games) for 12 weeks, with 60 min sessions. The two groups will be assessed at baseline and 12 weeks later. The KTK3+ will be used to assess MC. A between–within ANOVA-RM (2 [groups] × 2 [time points]) will be conducted. The results and conclusions of the implementation program will be presented in another study.
