The Use of Simulators in Training for Bovine Reproductive Procedures: A Scoping Review
Get PDFTraining in bovine reproduction requires not only technical proficiency but also ethical responsibility and adherence to animal-welfare standards. Traditional instruction relies heavily on repeated practice in abattoir-collected specimens and live cattle, raising concerns about stress, variability, logistical constraints, and student anxiety. Simulation-based education (SBE) has therefore emerged as a pedagogically robust and ethically sound complement to clinical teaching, enabling learners to acquire psychomotor and cognitive skills in structured, low-risk environments. This scoping review synthesizes current evidence on validated simulators used to train bovine reproductive procedures, with particular emphasis on artificial insemination, transrectal palpation, and pregnancy diagnosis. Following Arksey and O’Malley’s framework, a comprehensive search of three international databases identified 13 eligible studies that described simulator typologies, validation approaches, implementation strategies, and educational outcomes. Simulators ranged from low-cost handmade models to high-fidelity haptic and hybrid systems, each offering distinct advantages across diverse instructional contexts. Evidence consistently showed that simulator-based training improves anatomical orientation, technical performance, procedural efficiency, and learner confidence, while reducing anxiety and the need for novice practice on live cattle. However, validation standards remain inconsistent, long-term transfer to clinical practice is poorly documented, and most commercial models inadequately represent Bos indicus anatomy, limiting global applicability. Simulation can substantially strengthen competency-based animal and veterinary curricula and advance the 3Rs by replacing or refining early live-animal procedures. To fully realize this potential, future efforts should prioritize rigorous validation, greater anatomical representativeness, and improved accessibility through modular, low-cost designs. Simulation-based training thus represents both an educational innovation and an ethical imperative in modern veterinary practice
Family tourism perceptions: Are there differences between Portuguese fathers and mothers?
Get PDFResearch on family tourism indicates the existence of distinct perceptions between fathers and mothers regarding effects and motivations. While some studies suggest these differences, a comprehensive comparative and quantitative analysis is lacking in the current literature. Therefore, the present chapter aims to explore differences between mothers' and fathers’ perspectives on family tourism motivations and effects (on individuals and on the family), using a comparative and broader perspective. A quantitative approach was taken, and a survey (N=816) was conducted with Portuguese families with children, in order to test whether differences exist between mothers and fathers regarding those aspects. Results reveal differences in family tourism motivations and the effects of family tourism on individuals and the family when considering mothers' or fathers’ perspectives. Results also highlight the need to adapt the type of holiday to each family when the objective is to maximize the positive effects of family tourism
Geodesic languages for rational subsets and conjugates in virtually free groups
Get PDFWe prove that a subset of a virtually free group is rational if and only if the language of geodesic words representing its elements (in any generating set) is rational and that the language of geodesics representing conjugates of elements in a rational subset of a virtually free group is context-free. As a corollary, the doubly generalized conjugacy problem is decidable for rational subsets of finitely generated virtually free groups: there is an algorithm taking as input two rational subsets and of a virtually free group that decides whether there is one element of conjugate to an element of . For free groups, we prove that the same problem is decidable with rational constraints on the set of conjugators.FC
Impacts of Sustainable Mindset Vs. Fixed Mindset on Psychological Well-being in Portuguese Youth.
No full textThis study investigates the impact of a sustainable mindset on psychological well-being and stress levels among 736 Portuguese students from secondary schools and universities. Using validated psychometric instruments, the research examines relationships between well-being, stress, optimism, age, sex, and mindset orientations (Growth Mindset and Fixed Mindset). Findings indicate that higher psychological well-being is significantly associated with a Growth Mindset, correlating with better mental health and lower stress levels. In contrast, a Fixed Mindset is linked to lower well-being and higher stress. Gender differences were noted, with females exhibiting higher Growth Mindset scores and males showing higher Fixed Mindset scores. Multiple regression analyses reveal that well-being and age are strong predictors of mindset orientations for both genders. This study underscores the importance of developing youth policies focused on enhancing well-being and managing stress to promote adaptive mindsets and sustainable attitudes. Such initiatives could foster resilience and positive behavioral changes necessary for long-term sustainability in educational settings. The results provide a foundation for future research and practical applications aimed at integrating psychological sustainability into educational practices
Impact of a High-PAR-Transmittance Plastic Cover on Photosynthetic Activity and Production of Cucumber (Cucumis sativus L.) Crops in aMediterranean Solar Greenhouse
No full textThe optical properties of greenhouse cover materials play a critical role in controlling
the internal light environment, directly affecting photosynthetic performance and crop
productivity. This study evaluates the impact of a high photosynthetically active radiation
(PAR) transmittance and high-light-diffusivity polyethylene film on the microclimate, photosynthetic activity, yield, and disease incidence of cucumber (Cucumis sativus L.) crops grown in a Mediterranean passive solar greenhouse. Trials were conducted over two consecutive autumn–winter seasons using a multi-span greenhouse divided into two sectors: one covered with an experimental high-transmittance film and the other with a standard commercial plastic. The experimental cover increased PAR transmission by 8.7% and 11.6% at canopy level in the first and second seasons, respectively, leading to improvements in leaf-level net photosynthesis of 9.3% and 17.9%. These effects contributed to yield increases of 5.0% and 17.3% in the respective seasons. The internal air temperature rose by up to 1.3 ◦C without exceeding critical thresholds, and no significant differences were observed in plant morphology or fruit quality between treatments. Additionally, the
experimental film reduced the incidence of major fungal diseases, particularly under higher disease pressure conditions. The use of high-PAR-transmittance films enhances radiation use efficiency and crop performance in resource-limited environments without increasing
energy inputs. This approach offers a sustainable, low-cost strategy to improve yield and disease resilience in protected cropping systems under passive climate control

Águas subterráneas en Portugal y España durante la segunda mitad del siglo XX
No full textResumo:
Águas subterrâneas em Portugal e Espanha durante a segunda metade do século XX -
Durante as ditaduras de Franco e do Estado Novo, os aquíferos começaram a ser
intensamente explorados em Espanha e Portugal, graças ao apoio dos aparelhos públicos (através
de regulamentos, financiamento e estudos) e à existência de novas tecnologias. Nas duas últimas
décadas do século XX, as primeiras investigações sistemáticas forneceram dados sobre as águas
subterrâneas em ambos os países e revelaram a situação de sobre-exploração e poluição deste
tipo de águas em inúmeras áreas. Esta tese tem como objetivo decifrar as razões históricas de um
processo de deterioração dos aquíferos que se tem prolongado, quiçá agravado, até aos dias de
hoje.
Em primeiro lugar, a tese aborda o tratamento jurídico deste recurso, cujo aproveitamento
foi deixado nas mãos de quem controlava o solo no século XIX e no início do século XX. À
medida que o interesse político pelos aquíferos aumentou, especialmente na década de 1950,
foram introduzidas reformas, mas até hoje, não conseguiram transformar completamente a visão
de que o acesso à água subterrânea é um direito particular, nem as possibilidades de uma gestão
hídrica pública ou coletiva.
Em segundo lugar, a tese aborda a receção das ajudas norte-americanas durante a década
de 1950 nos dois países, o que estimulou a atividade de prospeção de águas subterrâneas com
recurso a tecnologia moderna. Por outras palavras, existia capital e equipamentos para realizar
explorações mais profundas, mas faltava o mais importante: o conhecimento para realizar esta
prática.
A partir da década de 1970, organismos internacionais e diversos movimentos sociais
lançaram as bases para uma visão diferente da água, a chamada nova cultura da água, que, no
entanto, teve um impacto limitado na política pública e nas práticas sociais; - Abstract:
Groundwaters in Portugal and Spain during the second half of the 20th century -
During the Francoist and Estado Novo dictatorships, Spain and Portugal began an
intensive exploitation of aquifers thanks to the support of public apparatus (through regulations,
funding, and studies) and the existence of new technologies. The last two decades of the 20th
century saw the first systematic research offering data on subterranean water in both countries,
which highlighted the overexploitation and contamination of groundwater in numerous locations.
This thesis attempts to unravel the historical reasons for the process of aquifer degradation that
has endured, if not worsened, to the present day.
First, the thesis deals with the legal status of the resource whose exploitation was left to
those who controlled the land in the 19th and first half of the 20th centuries. As political interest in
aquifers increased, particularly in the decade of the 1950s, reforms were introduced. However, to
date it has not been possible to fully change the view that access to groundwater constitutes an
individual right, nor to explore the possibilities of a public or collective management of water
resources.
Secondly, the thesis deals with the reception of North American aid by both countries in
the 1950s, which stimulated prospection for groundwater using modern technologies. However,
although both the equipment and the capital existed to conduct deeper exploration, the most
important element to do so, knowledge, was lacking.
From the 1970s, international authorities and diverse social movements laid the
foundations for a different view of water, establishing what is known as the ‘new water culture’
paradigm; however, this had little impact on public policies and social practices
Territorial embeddedness of sustainable agri-food systems. A systematic review
No full textThe current food systems require an urgent transition toward more sustainable food landscapes. One key discussion arising is on the potential of territorial approaches to foster the sustainability of agri-food systems, for which this paper provides a review. This systematic literature review is based on bibliometric methods which allowed us to identify in a fairly unbiased manner the most impactful authors, papers, and research trends. Three distinctive scientific fronts are identified, revealing research specializations defined by their distinctive social-territorial approach: sustainable agroecosystems at the farm level; agroecological initiatives at the community level; and transformation of the food system and societal values at the regional/national level. We expect this review will trigger and enrich further discussions about future trends and opportunities for enhancing the sustainability of agri-food systems. This is especially urgent since research on these topics is relatively recent, and conflicting approaches are identified for which an overall understanding of potential solutions is largely missing. Reconciling agricultural and biodiversity sustainability stands on top of current political agendas, and thus providing an overall picture of how territorial approaches confront this problem shall prove key in guiding better-informed land policy and management decisions
