    No full text
    Food loss and residues have attracted the attention of many sectors around the world due to negative environmental and economic effects. Several studies identify this bioresidue with potential to be explored and used as natural ingredients, benefiting environment and economy, and producing functionalized products. This study aimed at the nutritional, chemical and bioactive evaluation of flours obtained from apples discarded as bioresidue due to their low caliber or non-standard format. The nutritional evaluation of the flour highlighted an interesting protein and ash content. Three free sugars were identified in the analyzed flour, with fructose being the main sugar and five organic acids, with malic acid being the most prevalent. Regarding fatty acids, monounsaturated fatty acids predominated, with oleic and linoleic acids being the major components. Seven phenolic compounds were identified by HPLC-DAD-ESI/MS, divided into three different families: phenolic acids, flavan-3-ols, and dihydrochalcone, with phenolic acids predominating, which may justify the antioxidant and antimicrobial potential evidenced by the flour. After characterization, flour was incorporated into two types of bread and the effect of this incorporation over the shelf life was evaluated. Overall, the nutritional and chemical composition of the apple flour obtained in this study makes it a viable alternative for application in the bakery and pastry industry, thus creating alternative products and health promoters for the consumer. Additionally, the reuse of apple bioresidue will allow the recovery of waste discarded annually without added value, in addition to contributing to a positive impact on the economy and the environment.This work was supported by national funds through FCT/MCTES (PIDDAC): CIMO, UID/00690/2025 (10.54499/UID/00690/2025) and UID/PRR/00690/2025 (10.54499/UID/PRR/00690/2025); and SusTEC, LA/P/0007/2020 (https://doi.org/10.54499/LA/P/0007/ 2020).

    AI-enhanced neuromarketing and social media communication: evidence from PLS-SEM analysis in an academic context

    No full text
    Artificial intelligence (AI) is reshaping neuromarketing by enabling the real-time analysis of neurometric, biometric, and psychometric data to optimize consumer engagement. This study investigates how AI-enhanced neuromarketing influences social media marketing strategies, using a structural equation modeling (PLS-SEM) approach to assess relationships between neuromarketing knowledge, application, activities, and social media communication. Data were collected through a survey of 416 Romanian university students and professors with practical exposure to neuromarketing tools in educational environments. The results confirm that neuromarketing knowledge significantly improves practical application (β = 0.726, p < 0.001), which in turn enhances both marketing activities (β = 0.555, p < 0.001) and social media communication effectiveness (β = 0.633, p < 0.001). AI was found to amplify these effects through predictive analytics, real-time consumer data processing, and automated content optimization. Ethical considerations—such as privacy risks and algorithmic bias— are acknowledged, and the academic sample limits generalizability to commercial contexts. Future research should explore cross-industry applications, diverse cultural settings, and longitudinal impacts to strengthen external validity

    No full text
    O presente artigo resulta de um enquadramento teórico em torno do desafio da ética nos meios de comunicação social em Moçambique e as suas implicações no contexto social. O objetivo da pesquisa é identificar os desafios éticos enfrentados pelos meios de comunicação social e como, por vezes, podem distorcer a narrativa pública, comprometendo a confiabilidade da informação. Para o alcance do objetivo recorreu-se à consulta bibliográfica, tendo sido efetuada uma pesquisa no Google Scholar, com base em um conjunto de palavras-chave, de artigos dos últimos 4 anos. Os resultados evidenciam que os meios de comunicação social têm um desafio maior na geração de um conteúdo compreensível, com indícios de aproximação máxima da veracidade, geradora de confiança e credibilidade. Também os problemas éticos na cobertura jornalística estão fixados em vários aspectos, entre eles, os de interesses empresarial e político, presentes nos grandes conglomerados de mídia privados ou em grupos públicos, com interferência político-partidária

    Avaliação da alteração do conhecimento sobre AVC em estudantes do 11.º ano após o curso SomosUm

    O Acidente Vascular Cerebral (AVC) caracteriza-se pela interrupção súbita do fluxo sanguíneo cerebral, causada por isquemia ou hemorragia, resultando em danos neurológicos, representando um elevado impacto nos sobreviventes (Peixoto, 2023). A World Stroke Organization (WSO) considera o AVC como a segunda causa de morte no mundo, e quando está, combinado com a incapacidade resultante da doença AVC, é a terceira causa no mundo (Feigin et al., 2022). No entanto, em Portugal, o AVC é a principal causa de incapacidade e de morte, apesar de esta doença, ser prevenível (Costa et al., 2022). É comumente identificado pela população por 3 típicos sinais de alerta, que são: a dificuldade em falar, a boca ao lado e a falta de força num membro. Pode ainda apresentar outras manifestações clínicas, de acordo com o território afetado, e estar associado a inúmeros fatores de risco vasculares. Neste sentido, o conhecimento da população e a correta identificação, é fundamental, pois quanto mais rápido for acionado o serviço de emergência através do 112, mais célere será o tratamento do indivíduo (Costa et al., 2022). Em Portugal, existe uma preocupação crescente em desenvolver estratégias integradas para a promoção de políticas de saúde e para o aumento do conhecimento e da literacia em saúde. O reflexo disto, é a criação do plano de ação para a Literacia em Saúde 2019-2021 (PALS 2019-2021) e um plano estratégico, designado como Plano Nacional de Literacia em Saúde e Ciências do Comportamento 2023-2030, como resposta à necessidade de promoção de comportamentos e ambientes salutogénicos, que permitam a adoção de estilos de vida saudáveis e consequentemente, obter ganhos em saúde (Arriaga et al., 2023). O nível de conhecimento em saúde da população portuguesa acerca do AVC é reduzido, sendo um dos principais fatores que fomentam a baixa ativação do Serviço Integrado de Emergência Médica (SIEM), traduzindo-se em tempos pré e intra-hospitalares superiores às janelas de tempo terapêuticas recomendadas. A promoção do aumento do conhecimento em saúde sobre a doença de AVC, o reconhecimento dos sinais e sintomas de alerta desta doença e como atuar em caso de paragem cardiorrespiratória são cruciais (Costa et al., 2022; Cherfane et al., 2025). Neste sentido, investir em estratégias de promoção educacionais sobre esta temática, de modo a existir uma população instruída e capaz de agir rapidamente perante um AVC, é primordial, e percebe-se que em iniciativas de exposição de informação sobre o AVC, promove o aumento do conhecimento geral da população sobre a doença (Costa et al., 2022; Cherfane et al., 2025). O SomosUm® visa dar resposta ao baixo nível de conhecimento em saúde, e consequentemente, a iliteracia em saúde, sendo um projeto que aborda a formação em Suporte Básico de Vida (SBV) certificado pelo Instituto Nacional de Emergência Médica(INEM), contemplando igualmente, a formação sobre reconhecimento precoce de sinais de AVC e Enfarte Agudo do Miocárdio (EAM)

    Pacing of the first and only female finisher in the world's longest triathlon: The 2024 Triple Deca ultra triathlon

    No full text
    Pacing in triathlon has been analyzed for distances up to 60 long-distance triathlons in 60 days in men. However, no study has examined pacing in a female ultra-endurance triathlete in a multi-day triathlon exceeding 10 days. Thus, this case study analyzes the pacing of the first and only woman to complete 30 long-distance triathlons in 30 days. Methods: Lap times for swimming, cycling, and running, including transitions, were collected from race results. The athlete tracked each discipline daily using a Fenix 7 Sapphire Solar, recording average and maximum heart rates and energy expenditure. The coefficient of variation and second-order polynomial regression were calculated for average pace, split, and total times. Repeated measures ANOVA tested interactions in pace performance across 10-day phases and intra-discipline daily pacing variations. Multivariate regression examined physiological parameters' impact on pacing. Results: The female triathlete maintained a relatively even pacing strategy throughout the race, with a decrease in cycling speed and an increase in running speed. Cycling showed the strongest and significant correlation with total race time (r = 0.810; p < 0.001), while running (r = 0.347; p = 0.119) and swimming (r = -0.312; p = 0.165) displayed non-significant associations. The pace varied within the disciplines, with cycling becoming slower and running faster in the last quarter of the race. Energy expenditure, maximum and average heart rate were significant predictors for cycling (R-2 = 0.538; p < 0.001), while only average heart rate was the best predictor for running performance (R-2 = 0.450; p < 0.001). Conclusions: Tactical considerations most likely influenced pacing, particularly in cycling and running. Future research should further explore pacing strategies in ultra-endurance events

    Smart villages in practice: A meta-synthesis of implementation experiences in Europe

    Full text link
    The concept of Smart Village, created by the European Commission in 2017, emerged as a response to the challenges faced by low-density territories, by promoting strategies based on local potential, opportunities, and digital technologies, using participatory approaches in their design. This study analyzes how the Smart Village concept has been implemented in European rural territories and what conclusions can be drawn about this strategy from the available empirical evidence. Based on inductive analysis and synthesis, this study seeks to understand how the initiatives were configured and which elements had influenced their implementation processes. To this end, 22 scientific articles retrieved from the Web of Science and Scopus databases were analyzed, along with 14 projects from the “Smart Rural Areas in the 21st Century” program. The main findings highlight the importance of involving multiple actors in the formulation and sustainability of the initiatives, the absence of instruments for monitoring strategies, and the challenges in implementing and adopting digital technologies. These findings contribute to understanding how projects and initiatives are configured, revealing operational gaps and asymmetries between declared objectives and the ways in which the initiatives have been designed and implemented in rural contexts.This work was supported by the FCT - Foundation for Science and Technology and Côa Park Foundation under Grant PRT/BD/153,395/2021

    Physical activity during pregnancy: associations between levels and types of physical activity and low back pain–related disability in portuguese pregnant women

    No full text
    Low back pain (LBP) is one of the most prevalent musculoskeletal conditions during pregnancy and frequently impairs daily living activities and quality of life. The association between different levels and types of physical activity (PA) and LBP-related functional disability remains insufficiently explored. This study aimed to examine the association between PA levels and types and functional disability among pregnant women with LBP. A cross-sectional analytical study was conducted involving 192 Portuguese pregnant women. Data were collected through an online questionnaire comprising the Pregnancy Physical Activity Questionnaire and the Oswestry Disability Index (ODI). Most participants engaged predominantly in light-intensity or sedentary activity (69.1%), with minimal participation in vigorous activity (0.8%). Functional disability was generally mild (mean ODI = 11.5 ± 7.35); however, 42.2% of participants reported moderate disability and 11.0% severe disability. Advancing gestational age showed weak associations with increased domestic activity (r = 0.146, p = 0.044), decreased occupational activity (r = −0.295, p = 0.001), and higher functional disability scores (r = 0.142, p = 0.049). Parity was associated with differences in total PA levels (p = 0.005) and domestic activity (p = 0.001). Higher ODI scores were weakly associated with light-intensity and sedentary activity (r = 0.144, p = 0.047), whereas severe disability demonstrated a moderate association with sedentary behavior (r = 0.529, p = 0.014). Overall, lower levels of PA, particularly sedentary behavior, were weakly associated with higher LBP-related disability; however, the observed associations were generally weak and should be interpreted with caution considering the cross-sectional design

    Assessment of Digital Teaching Skills: a pilot study based on the precepts of Digcompedu

    No full text
    This study aimed to evaluate the level of digital competence of a group of 17 teachers by applying a questionnaire of the European Digital Competence Frame- work for Educators DigCompEdu [1]. With this information, we aimed to evaluate which are the areas of mastery and use of digital technologies in which there is less development of skills and use of these technologies when these professionals work in the classroom. This diagnostic will be part of a pilot study that will be the mate- rials and methods of a study of bigger proportions, with a larger number of teachers. Therefore, the participants accessed the questionnaire on the DigCompEdu plat- form, and we collected their answers. The answers were analyzed and the teachers’ scores allowed to classify them into six levels of digital competence based on the metrics proposed by DigCompEdu questionnaire. The results allowed us to identify that most teachers present intermediary levels of digital competence development, being classified with the general score B2 and present a good comprehension of the use of technological resources in the classroom. However, they not always show the necessary criticism and history of experimentation to dare to implement different tools. Finally, it was possible to identify the existing gaps in the digital competence of teachers, making it possible to map the points that need to be worked on, thus allowing these teachers to make autonomous and assertive decisions regarding their professional training.Acknowledgements This research was developed with the support of the Brazilian Council for Scientific and Technological Development, Brazil.info:eu-repo/semantics/publishedVersio
