- Natural establishment of Eucalyptus globulus Labill. in burnt stands in PortugalPublication . Águas, Ana; Ferreira, António; Maia, Paula; Fernandes, Paulo M.; Roxo, Luís; Keizer, Jan; Silva, Joaquim S.; Rego, Francisco C.; Moreira, FranciscoExotic tree species are increasingly common in many regions of the world and at least some species are becoming naturalized in the regions where they were introduced. Disturbances like fire may be at the origin or accelerate the naturalization of these species. Portugal holds one of the largest areas of exotic Eucalyptus globulus plantations in the world and is one of the countries most affected by forest fires. These two facts have triggered the present research. This study aimed at characterising medium-term natural establishment of E. globulus plants originated from seeds under natural conditions in burnt planted forests (pure E. globulus stands, pure Pinus pinaster stands, and mixed stands of both species), and at analysing factors associated with this establishment. Occurrence, abundance and height of naturally established E. globulus plants were characterized in 284 sites distributed in burnt areas, across Central and Northern Portugal, 5–7 years after wildfire. Generalized linear models were used to assess the influence of stand type, regional productivity potential, and post-fire management practices on occurrence probability, density, and median height of sampled E. globulus individuals. The influence of these explanatory variables on the structure (in terms of size class distribution) of naturally established E. globulus cohort was examined using analysis of similarity and non-metric multidimensional scaling. Naturally established E. globulus plants were present in 93.1%, 19.0% and 98.6% of samples in pure E. globulus, pure P. pinaster and mixed stands, respectively. Cohort median density was 0.20 plants m−2 and maximum density was 4.55 plants m−2. Median height of plants was 2.0 m and 95.3% of them had h >1.30 m and DBH ⩽5 cm. Establishment probability, density and median height were highest in the most productive regions. Three post-fire management operations had a significant influence on the response variables: (i) salvage logging was associated with a higher density; (ii) tillage was associated with a lower density and a smaller median height; (iii) understorey removal was associated with a lower occurrence probability. Tillage was the only studied factor influencing the size structure of spontaneously established cohort, eliminating larger plants. This study showed that stand type, productivity region and post-fire management operations might have significantly influenced the natural establishment of E. globulus in burnt areas, and consequently the species naturalization process in Portugal. The implications of these findings for management are discussed.
- Changes in lifestyle and physical fitness in the first year of higher education: A longitudinal study with sports studentsPublication . Jacinto, Miguel; Antunes, Raul; Aguiar Santos, Diana; Duarte-Mendes, Pedro; Diz, Susana; Monteiro, Diogo; Matos, Rui; Amaro, NunoThis study aimed to monitor variations in physical activity and fitness levels throughout the first academic year in undergraduate Sports Science students. A prospective longitudinal design included 63 students (46 men, 17 women; 19.7 ± 1.4 years), assessed at four moments (September, January, February, and June). Sociodemographic data were collected, and instruments included IPAQ, anthropometry, body composition, strength, flexibility, and cardiorespiratory fitness tests. Repeated measures ANOVA with Bonferroni correction was applied. Screen time increased significantly over the year. Physical activity levels showed a non-significant decline. Body composition indicators such as fat mass, BMI, and visceral fat increased, while lean and bone mass remained stable. Cardiorespiratory fitness and lower limb flexibility decreased significantly. These findings suggest worsening fitness and increased adiposity over the duration of the first academic year, highlighting the importance of monitoring such indicators to prevent negative health outcomes.

- The Role of Body Image Discrepancy in Exercise and Eating Motivation: A Self-Determination Theory PerspectivePublication . Salvador, Rogério; Cordeiro, Filipa; Castuera, Ruth Jimenéz; Rebelo-Gonçalves, Ricardo; Monteiro, DiogoBackground/Objectives: While body dissatisfaction is frequently studied as an outcome of physical activity, less is known about how pre-existing body image perceptions shape the quality of behavioral regulation. Grounded in Self-Determination Theory, this study aimed to investigate the associations of different perceived body image discrepancy profiles with autonomous and controlled motivation for both exercise and eating, and to explore the interaction effects between these profiles and sex. Methods: The sample comprised 939 regular gym exercisers (32.99 ± 11.90 years; 55.1% female). Using the Stunkard Figure Rating Scale, participants were categorized into four discrepancy profiles: desire to increase, satisfied, mild desire to reduce, and moderate/severe desire to reduce. Data were analyzed using Two-Way ANOVAs. Results: The Satisfied group reported the highest autonomous and lowest controlled motivation across both domains (main effects: p < 0.001, η2p = 0.019–0.046). A significant body image × sex interaction emerged for controlled eating motivation (F(3, 931) = 6.22, p < 0.001, η2p = 0.020). Females exhibited a “U-shaped” curve, demonstrating low controlled eating motivation when satisfied (M = 1.65) but elevated levels at extremes (desire to increase: M = 2.50; moderate/severe desire to reduce: M = 2.39). Males maintained stable controlled eating motivation across all discrepancy profiles (M = 2.06–2.30). Although these main and interaction effects were statistically significant, all observed multivariate effect sizes were small (η2p = 0.012–0.046). Conclusions: Perceived body image discrepancy acts as a significant antecedent of motivational quality. The absence of a perceptual gap is linked to highly adaptive, autonomous behavioral regulation. Furthermore, the distinct sex-based patterns in controlled eating motivation underscore the necessity for health and exercise professionals to adopt tailored, sex-specific strategies when addressing body image concerns.
- Determinantes de la eficacia del patrocinio en las carreras de atletismoPublication . Silva, Alfredo; Sobreiro, Pedro; Monteiro, DiogoIntroduction: The athletics races take place in the heart of public space and enjoy high levels of visibility. Race organizers benefit from connecting with sponsoring companies that want results in promoting and selling their brands. Objective: The aim of the research was to test a conceptual model to explain the effects of sponsorship on runners. It used running involvement, perceived altruistic sponsor motives, brand recognition and perceived congruence between sponsors and running as the determining constructs. Methodology: This research shifts the focus from spectator-based sponsorship to participant-based sponsorship. A sample of 736 runners from one of Portugal’s most popular athletics races completed a questionnaire. A Structural Equation Modeling analysis was carried out to test the model and the hypotheses. Results: The model explained that 49% of attitudes toward sponsors and 15% of runners' purchase intentions. The strongest effects were the effect of brand recognition on perceived congruence and the effect of perceived altruistic motives on attitudes toward the sponsor brand. However, running involvement had no significant effect on attitude towards the sponsoring company. Discussion: This research demonstrates the role played by perceptions of sponsors' altruistic motivations in shaping favourable responses to sponsoring companies and runners' intention to buy sponsors' products. Conclusions: The effects of sponsorship of athletics races on runners have been demonstrated, particularly the significant role of brand recognition and perceived altruistic motives. This study offers important implications for race organizers and sponsoring companies.
- Short-interval consecutive goals and performance outcomes in elite women’s futsalPublication . Carvalho, Rute; Monteiro, Diogo; Costa, Júlio A.; Sampaio, Jaime; Travassos, BrunoThe goal of this study was to examine the impact of short-interval consecutive goals (SICGs), defined as ≥ 2 goals scored within three minutes, on team performance in elite women’s futsal. Goal timings from 132 matches of the 2024–2025 Portuguese Women’s Senior Futsal League were extracted from official reports. Goals inside and outside SICGs, match result, and league ranking were recorded. Path analysis using Structural Equation Modelling (SEM) tested model fit and direct and indirect paths among all variables. SICGs occurred in most matches and accounted for over half of all goals, clustering in the opening and closing periods of each half. Scoring SICGs was positively associated with points (β = .30, p = .003), whereas conceding SICGs was negatively associated (β = −.24, p = .003). Combined, these effects explained 50% of the variance in points earned and 40% in final league ranking. SICGs appear to be critical tactical and psychological junctures in elite women’s futsal, with implications for match outcomes and season-long classification. Coaches may benefit from anticipating these high-leverage periods to enhance match management and prepare players for moments of advantage or disadvantage. Future research should clarify the role of SICGs in psychological momentum.
- Hope and positive affect mediating the authentic leadership and creativity relationshipPublication . Rego, Arménio; Sousa, Filipa; Marques, Carla; Cunha, Miguel Pina eThe study analyzes how authentic leadership (AL) predicts employees' creativity both directly and through the mediating role of employees' positive affect and hope. Two hundred and three employees working in Portuguese retail organizations participate in the research. Employees report their hope and positive affective states, as well as the AL of their supervisors. Supervisors report the employees' creativity. The main findings are: (a) AL predicts employees' creativity, both directly and through the mediating role of employees' hope; (b) AL also predicts employees' positive affect, which in turn predicts employees' hope and, thus, creativity. The study enriches the understanding of the processes through which AL improves employees' creativity, and provides valuable insights for both scholars and practitioners. By promoting AL, and employees' hope and positive affect, organizations may increase employees' creative performance, creativity being an important path to organizational performance.
- Peer relations: The challenges of children with special needsPublication . Soares, Elsa Marta; Serrano, Ana MariaChildren with special needs, due to the greater likelihood of developing a disorder in one or more areas of their development, and due to the obstacles they may find in the context, can have their social performance compromised, which can entail consequences in short and in long term. It is, therefore, essential to know the factors that may influence the development of their peer related social competence. Only then can the caregivers play an active role in order to increase the chances of stimulating these competencies. This review addresses the perspectives of different authors about the social development of children with their peers. It is at the convergence of each of these perspectives that one can find the complementarity needed to effectively understand the dynamism and the inter-relational characteristics inherent to social competence.
- Ficar ou voltar? Intenções de regresso entre portugueses qualificados emigrados a partir do ano 2000Publication . Pinho, Filipa; Góis, Pedro; Marques, José Carlos LaranjoÉ escassa a investigação sobre o regresso de emigrantes portugueses recentes. Neste artigo, apresentamos um estudo sobre intenções de regresso baseado numa amostra de 1100 emigrantes portugueses qualificados, respondentes a um inquérito online, realizado em 2017. O estudo apresenta contextos, protagonistas e o momento histórico em que as intenções são reveladas e os regressos podem acontecer. Analisam-se as intenções de regresso de acordo com variáveis explicativas como a idade, o país de residência, o tempo da imigração no país, entre outros fatores que, em Portugal e no destino, contribuem para explicar as intenções de regresso afirmadas pelos respondentes.
- A importância da animação sociocultural no combate ao envelhecimento das instituiçõesPublication . Trindade, Bruno; Pocinho, Ricardo; Carrana, Pedro; Santos, Gisela; Serrano, João JúlioObjetivo: Analisar o impacto que as atividades de animação sociocultural têm na qualidade dos serviços prestados no âmbito da terceira idade, percecionado pelos respetivos profissionais da animação sociocultural. Pretende-se verificar a importância que a profissão revela ter na qualidade das instituições e das respostas sociais no âmbito da terceira idade e do envelhecimento saudável. Metodologia: Foi realizado um diagnóstico a nível nacional sobre o contexto laboral dos animadores socioculturais, o seu exercício profissional, as expetativas relativamente ao futuro da atividade, à qualidade e ao impacto das suas práticas profissionais no âmbito da terceira idade. A amostra de 134 animadores socioculturais respondeu a um questionário online sobre a prática profissional e o impacto das instituições da terceira idade. Resultados: verificou-se que os animadores socioculturais consideram a prática das atividades importantes nestas instituições, contribuindo de forma positiva para a qualidade de vida das pessoas idosas. A animação sociocultural parece ter um impacto positivo na qualidade dos serviços, sendo fator diferenciador entre as instituições. Constitui, por isso, instrumento de promoção empresarial/institucional. Conclusão: O impacto das atividades parece ser bastante positivo na melhoria da qualidade das respostas sociais e atividades oferecidas.
