With the rapid development of onshore solar power plants in China, land resources have gradually become scarce. To explore alternative solutions, floating photovoltaic (FPV) systems have garnered significant attention, particularly the offshore floating photovoltaic (OFPV) systems. Beyond saving land resources, offshore wind power plants and offshore PV power plants exhibit complementarity in their power generation profiles. However, the most critical challenge lies in the high capital expenditure (CAPEX) of OFPV systems, and the industry has not yet reached a consensus on a mature design scheme. In this study, to reduce the cost of OFPV systems, a three-column OFPV platform with an asymmetric water-area layout is proposed, and a feasibility analysis is conducted accordingly. For the purpose of comparative research, two types of platforms are introduced as reference: the truss-spar platform and the classic four-column semi-submersible platform.

Background/Objectives: Mental health challenges are increasingly prevalent among higher education students, with significant implications for academic success and personal development. Emerging research suggests that critical thinking dispositions may support psychological well-being by enhancing resilience and adaptive coping. This study aimed to investigate the relationship between critical thinking dispositions and psychological well-being and to identify key sociodemographic predictors in this context. Methods: A cross-sectional design was employed from December 2024 to May 2025, recruiting 429 students from Portuguese higher education institutions via convenience sampling. Participants completed validated self-report measures: the Critical Thinking Dispositions Scale (CTDS) and the Psychological Well-Being Scale (PWBS), assessing seven critical thinking dispositions and six well-being dimensions, respectively. Sociodemographic data were also collected. Descriptive statistics, independent t-tests, one-way ANOVA, Pearson correlations, and hierarchical multiple regression were used for data analysis. Results: Students demonstrated moderate to high levels of critical thinking and psychological well-being, with higher scores associated with increased age and academic progression. Significant positive correlations were identified between critical thinking dispositions and all well-being dimensions; personal growth, purpose in life, and autonomy exhibited the strongest associations. Regression analysis revealed that confidence in reasoning, cognitive maturity, and open-mindedness were significant predictors of psychological well-being, explaining 28.7% of the variance. Conversely, inquisitiveness showed a negative association with psychological well-being in the multivariate model, an unexpected finding that warrants cautious interpretation and further investigation. Conclusions: Critical thinking dispositions reflect affective tendencies and habitual ways of engaging with thinking. These dispositions appear to protect psychological well-being in higher education students. Integrating the development of emotional awareness and reflective thinking into curricula may therefore foster resilience and academic success. Further longitudinal research is needed to explore causal mechanisms and intervention efficacy in broader academic contexts.

This article presents the <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">ScratchJr – Coding as Another Language</i> (CAL) curriculum, translated into Portuguese by researchers from the Arcacomum Association as part of a project funded by the Scratch Education Collaborative (2022–2024), part of the MIT Media Lab. The translation process was supported and validated by the DevTech Research Group (https://sites.bc.edu/codingasanotherlanguage/scratchjrcurricula-portuguese). Between February and May 2025, a pilot study was conducted in a preschool educational setting aimed at exploring the implementation of the curriculum’s lessons. The article describes the main features of the CAL curricula, highlighting their potential for cross-curricular integration across various areas of learning, from Kindergarten to the 2nd Grade of primary education. The results show benefits in terms of creativity, collaboration, communication, responsibility, and sense of community. The study concluded that the CAL curriculum is relevant within the Portuguese educational context, and its expansion and teacher training are recommended to enhance its implementation.

BackgroundPost-industrial societies that benefit from the development of science, technology and subsequent inventions that relieve people of everyday duties, have more free time, but face a greater temptation of laziness and limited physical activity. Common diseases increasingly resulting from limited physical activity, which is no longer just a way to spend free time, but a necessity in the field of health care. This necessity obliges us to undertake research that allows for recognizing factors influencing the level of physical activity in individual societies.ObjectiveThe conducted research aimed at identifying sociodemographic factors that would determine the level of physical activity in women and men from the Biała Podlaska district in eastern Poland.ParticipantsThe group involved 173 adults (71 women and 102 men) from eastern Poland.MethodsThe presented research was conducted in the years 2018–2020 as part of the international EUPASMOS Plus project. The collected sociodemographic data of the respondents and the results of physical activity monitoring with the use of the GPAQ questionnaire and the RM42 accelerometer − 24/7 allowed for an analysis of the factors determining the physical activity undertaken by the respondents, as well as the comparison of the obtained data with the use of the above-mentioned tools. The statystical analysis involved the use of the Shapiro-Wilk test, Mann-Whitney test and Spearman’s rho correlation analysis. The adopted standard significance level of α = 0.05.ResultsThe results of the research on sociodemographic factors conditioning the physical activity of the examined persons, obtained from the objective tool (Accelerometer RM42) and a subjective one for measuring physical activity (GPAQ questionnaire) showed some discrepancies. However, the established consistency of the research results using the above-mentioned tools allows for formulating the following conclusions: women from the Biała Podlaska district are more active than men. Older people more often undertake PA of lower intensity, giving up high-intensity efforts. The respondents declaring a higher subjective assessment of their health are more physically active.ConclusionsThe results obtained are varied and depend on the used tool. They indicate an enormous importance of the tool used in the study on physical activity.

Contemporary transformations in the world of work, together with the growing emotional and physical demands in nursing, have led to the emergence of new labor phenomena such as quiet quitting, which reflects changes in professional engagement and in the management of nurses’ well-being. Objective: To translate, culturally adapt, and validate the Quiet Quitting Scale for European Portuguese, evaluating its psychometric properties among the nursing population. Methods: A cross-sectional validation study was conducted following COSMIN guidelines. The process included forward and back translation, expert panel review, and pretesting with 30 nurses. The psychometric evaluation was carried out with 347 nurses from Northern Portugal. Data were analyzed using descriptive and inferential statistics, internal consistency measures (Cronbach’s α and McDonald’s ω), and confirmatory factor analysis (CFA) with maximum likelihood estimation to assess construct validity. Results: The Portuguese version (QQS-PT) maintained the original three-factor structure (Detachment/Disinterest, Lack of Initiative, and Lack of Motivation). The model showed satisfactory fit indices (CFI = 0.936; GFI = 0.901; AGFI = 0.814; TLI = 0.905; RMSEA = 0.133). The overall internal consistency was excellent (α = 0.918; ω = 0.922), with subscale α ranging from 0.788 to 0.924. Composite reliability (CR) ranged from 0.815 to 0.924, and average variance extracted (AVE) from 0.606 to 0.859, confirming convergent and discriminant validity. Conclusions: The QQS-PT demonstrated a stable factorial structure, strong reliability, and solid validity evidence. It is a brief and psychometrically sound instrument for assessing quiet quitting among nurses, providing valuable insights for research and management of professional engagement and well-being in healthcare contexts.

Sharks (Chordata: Chondrichthyes) can live in diverse environments and have distinct lifestyles. Several species migrate and are widely distributed worldwide, particularly deep-sea sharks. The Goblin shark (Mitsukurina owstoni) is a deep-sea shark species characterized by its elongated snout and protrusible jaws. The goal of this study was to review the global distribution of M. owstoni using QGIS, based on information from scientific publications in GBIF, BOLD Systems, and GenBank. Additionally, using DNA barcoding, two newly recorded individuals collected in Madeira, Portugal, in 2022, were analyzed, and global levels of genetic diversity and population differentiation were calculated, considering all available DNA sequences of this species. This showed that the Goblin shark is distributed globally and genetic diversity between individuals is low, with only two distinct haplotypes, one of which is present globally. In summary, there is probably only one active population, with no geographic structure and high connectivity between locations, due to this species’ migratory behavior.

Este estudo discute os desafios e possibilidades para a construção e consolidação de políticas linguísticas educacionais em contextos multilíngues e de fronteira, com foco na região da tríplice fronteira entre Brasil, Argentina e Paraguai. O objetivo é identificar e sistematizar ações e práticas pedagógicas em prol do acolhimento linguístico e cultural de migrantes internacionais e fronteiriços matriculados em instituições públicas de ensino brasileiras, analisando como tais ações podem se consolidar como políticas linguísticas educacionais. A pesquisa, de caráter qualitativo e bibliográfico, fundamenta-se em estudos de Políticas Linguísticas e em pesquisas e debates sobre acolhimento linguístico e cultural. Considerando o aumento, nas escolas brasileiras, do número de estudantes migrantes internacionais e fronteiriços cujas línguas maternas não coincidem com a língua oficial do país, o estudo parte de uma revisão sistemática da literatura para mapear ações voltadas à integração linguística e cultural desses alunos. A análise dos estudos identificados revela práticas que envolvem desde a gestão pública até a atuação docente, e destaca a importância de políticas que reconheçam e valorizem a pluralidade linguística como direito e patrimônio cultural. Conclui-se que iniciativas de ensino da língua de acolhimento, ainda que pontuais e situadas, apontam caminhos para a consolidação e construção de políticas linguísticas educacionais sensíveis à pluralidade linguística dos contextos fronteiriços, e que promovam o acolhimento de estudantes migrantes internacionais e fronteiriços, combatendo o silenciamento linguístico cultural.

<bold>Introduction:</bold> FEV1 and VO2peak assessment are essential for surgical risk stratification in lung resection candidates, as they help estimate respiratory complication risk and cardiorespiratory reserve. <bold>Aim:</bold> To characterize the role of FEV1 and VO2peak as predictors of postoperative medical complications in individuals undergoing lung resection. <bold>Methods:</bold> Cross-sectional retrospective study whose sample included 101 individuals who underwent CPET between 2015 and 2024 to assess surgical risk. Three classes were created according to FEV1 ( ≥80%, 60-79%, and <60%) and VO2peak (Low risk: ≥20 ml/kg/min, Moderate risk: 15–19.9 ml/kg/min, High risk: 10–14.9 ml/kg/min) to classify surgical risk. <bold>Results:</bold> Among this sample, 68 patients underwent surgery (67.3%), and 19 of them (27.9%) developed postoperative medical complications. Pneumonectomy was the procedure with more medical complications (33.3%), followed by lobectomy (32.5%) and segmentectomy (15.5%). No statistically significant differences (p >0.05) were observed in FEV1 and VO2peak between the groups with and without complications. The severity classes defined by FEV1 and VO2peak do not agree (Kappa=0.029), being individuals distributed differently depending on the parameter used for surgical risk stratification. The odds of developing postoperative complications increased as FEV1 decreased, with a cutoff point of FEV1 <60% — 1.56 times more likely to develop complications. <bold>Conclusion:</bold> FEV1 and VO2peak assess different components of the respiratory system, which is why they classify surgical risk differently. The authors emphasize the importance of considering both parameters in the preoperative evaluation of lung resection surgery.
