Predictive Machine Learning Models for Livestock Output
No full textAgricultural planning always had an important role in the performance of agriculture, but in our days this component of agricultural management seems to have an increased responsibility, because of the challenges imposed by the current contexts, specifically those related to the sustainability of the associated activities and processes. In fact, currently, it is important to reduce the environmental impacts of the farming dynamics and raise production to deal with the increased demand for food worldwide. The livestock activities are particularly complex and call for adjusted plans and management decisions. The new technologies associated with the digital transition may bring relevant added value, namely to predict outputs. This chapter aims to suggest models and predictors to support the farmers and other stakeholders to better design policies and farm plans. Statistical information from the European Union databases was considered. The results found are useful tools to improve the performance of the European Union farms, particularly those specialised in livestock production.info:eu-repo/semantics/publishedVersio

A saúde mental também vai a votos: a psicologia nos programas eleitorais
No full textIntrodução: A perceção pública da necessidade de garantir o acesso aos serviços de psicologia
e saúde mental tem vindo a crescer. Pretende-se, neste trabalho, explorar e comparar os
programas eleitorais para as eleições legislativas de 2019 e 2024, no que à psicologia e saúde
mental diz respeito. Método: Procedeu-se, para o efeito, a uma análise de conteúdo dos
programas eleitorais para as eleições legislativas de 2019 e 2024 dos vários partidos ou
coligações com assento parlamentar. Efetuou-se, num primeiro momento, a contabilização dos
termos: 1) psicologia/psicólogo/a/os/psicológico, 2) saúde mental, excluindo-se os índices e
títulos. Constituíram-se, num segundo momento, categorias. Resultados: No seu conjunto, em
2019, as propostas eleitorais dos vários partidos com assento parlamentar referiam 16 vezes os
termos psicologia/psicólogo/a/os/psicológico/a e 18 vezes a expressão saúde mental. Nas
propostas eleitorais de 2024 o número de referências subiu, respetivamente, para 69 e 106. As
principais categorias destacadas foram: compromissos de contratação de psicólogos;
investimento em saúde mental; criação de respostas específicas; programas de intervenção
comunitária e de promoção da saúde; carreira dos psicólogos e facilitação do acesso aos
serviços privados de psicologia. Discussão: Os resultados sugerem uma crescente preocupação
dos partidos políticos com o acesso aos serviços de psicologia e saúde mental, acompanhando
a perceção pública da relevância desta temática. Em muitos casos, todavia, esta preocupação
não se concretiza, ainda, em propostas concretas e integradas.Introduction: Public perception of the need to guarantee access to psychology and mental

integrated proposals.info:eu-repo/semantics/publishedVersio
Female Leadership in Wine Tourism in Portugal
No full textBased on data collected from managers of wine tourism businesses in
rural areas in Portugal, this study highlights the equal potential of female leadership in
wine tourism. Specifically, women’s profiles, management practices and leadership
narratives were analyzed and contrasted with corresponding data reported by their male
counterparts. Concerning personality traits, no statistical difference between men and
women was identified, which was also the case for some management practices, with
sustainability concerns being important for both male and female business managers.
Differences were found for communication with markets, being dominated by online
devices, particularly with social networks in the case of women. As for their leadership
position, women further tend to prefer a shared management approach in opposition to a
more individualist management style followed by men.This work is funded by National Funds through the FCT - Foundation for Science and Technology, I.P., within the scope of the project Refª UIDB/00681/2020. Furthermore,

Intervenção com uma Família sobre a Implementação de Regras e Limites
No full textAs famílias multidesafiadas são famílias em risco psicossocial, uma vez que as funções familiares são realizadas de forma insatisfatória. Nas famílias em risco existe uma maior probabilidade das crianças não receberem os cuidados básicos necessários.
O Centro de Apoio Familiar e Aconselhamento Parental (CAFAP) é uma resposta social em que o profissional intervém diretamente com a família, tendo como intuito ajudar a criar as competências parentais necessárias. Assim, os programas de educação parental são uma das principais estratégias. O CAFAP tem como principais objetivos proporcionar a parentalidade positiva, garantir a satisfação das necessidades emocionais e sociais das crianças e/ou jovens, entre outros.
O estágio foi realizado no CAFAP da Guarda, que tem como modalidades a Preservação Familiar, a Reunificação Familiar e o Ponto de Encontro Familiar, sendo esta uma das respostas das Aldeias SOS da Guarda. Esta resposta integra o Programa de Fortalecimento Familiar. Ao longo do estágio foram realizadas várias atividades, nomeadamente visitas domiciliárias; participação nas reuniões de equipa e nas supervisões externas; participação nos programas de educação parental, etc.
Para a intervenção realizada com uma família do CAFAP da Guarda, as atividades foram baseadas em três eixos de intervenção, e em cada eixo foram delineados objetivos a cumprir. O primeiro eixo foca-se na criação de atividades relacionadas com o estabelecimento de regras e limites, para tal foi efetuada a atividade do sistema de pontos. O segundo eixo destaca a realização de atividades baseadas numa disciplina positiva, sendo um dos objetivos a importância de elogiar o outro. O terceiro eixo prioriza o desenvolvimento das competências emocionais, como por exemplo aprendermos a autoelogiarmo-nos.
De forma geral, esta intervenção teve uma receção positiva, uma vez que a família demonstrou estar sempre disponível para qualquer necessidade que surgisse. As atividades foram fundamentais e de certa forma contribuíram para auxiliar tanto os pais quanto a criança envolvida.Multichallenged families are families at psychosocial risk, as family functions are performed unsatisfactorily.

Biochar as an Alternative Litter Additive to Mitigate Gaseous Emissions from Broiler Housing and Subsequent Storage
Get PDFBroiler farming is a significant source of gaseous emissions. The aim of this study was to
assess the effects of different litter additives on the emission of NH3, N2O, CO2, and CH4 during
broiler housing and subsequent manure storage. The gaseous emissions from the housing facilities
were evaluated during one fattening cycle in environmentally controlled rooms with three different
additives applied to the litter material (10% w/w aluminum sulphate or biochar and 2.50 mg m−2
urease inhibitor), as well as a control. A storage experiment was conducted under laboratory
conditions for 90 days to evaluate the influence of these three additives on gaseous losses. During
broiler housing, the results indicated that NH3 emissions were reduced significantly (40–60%) by
litter additives, while global warming potential (GWP) emissions were reduced significantly (31%)
by Alum. The addition of Biochar (a 58% reduction) had the same significant effect as Alum (a
60% reduction) to mitigate these losses. The re-application of Urease (a 41% reduction) may be
required to reach an equal or higher reduction. During storage, NH3 and GWP emissions were not
significantly affected by the litter additives. During broiler housing and subsequent manure storage,
NH3 emissions were reduced significantly (22–41%) by litter additives, whereas GWP emissions did
not decrease significantly. Globally, it can be concluded that Biochar appears to be a good alternative
to Alum due to its equal effectiveness in mitigating NH3 losses, without increasing the GWP potential
in the housing and avoiding pollution swapping.info:eu-repo/semantics/publishedVersio
Data Privacy and Ethical Considerations in Database Management
No full textData privacy and ethical considerations ensure the security of databases by respecting
individual rights while upholding ethical considerations when collecting, managing, and using
information. Nowadays, despite having regulations that help to protect citizens and organizations, we
have been presented with thousands of instances of data breaches, unauthorized access, and misuse
of data related to such individuals and organizations. In this paper, we propose ethical considerations
and best practices associated with critical data and the role of the database administrator who helps
protect data. First, we suggest best practices for database administrators regarding data minimization,
anonymization, pseudonymization and encryption, access controls, data retention guidelines, and
stakeholder communication. Then, we present a case study that illustrates the application of these
ethical implementations and best practices in a real-world scenario, showing the approach in action
and the benefits of privacy. Finally, the study highlights the importance of a comprehensive approach
to deal with data protection challenges and provides valuable insights for future research and
developments in this fiel

Edible Insects – Exotic Food or Gastronomic Innovation? Study Involving 14 Countries
Get PDFThis study explores the perceptions about edible insects and their usage in modern gastronomy. Data were collected through questionnaire survey in 14 countries, and 7222 responses were obtained. ANOVA and factor analysis were used, respectively to evaluate differences between groups and to analyze the scale items. The results showed that participants showed higher agreement toward insects being considered exotic foods and being associated with taboos and neophobia. Some sociodemographic factors (country, age class, education level and income) were proven to significantly influence with the perceptions. while sex and living environment did not. Factor analysis extracted three factors, one associated with the uses of insects in gastronomy, another associated with insects as foods and a third about insects not being proper for human consumption. In conclusion, the work revealed differences between countries in the perceptions about edible insects, and that these perceptions were also significantly influenced according to other sociodemographic variables
Revisiting Database Indexing for Parallel and Accelerated Computing: A Comprehensive Study and Novel Approaches
No full textWhile the importance of indexing strategies for optimizing query performance in database systems is widely acknowledged, the impact of rapidly evolving hardware architectures on indexing techniques has been an underexplored area. As modern computing systems increasingly leverage parallel processing capabilities, multi-core CPUs, and specialized hardware accelerators, traditional indexing approaches may not fully capitalize on these advancements. This comprehensive experimental study investigates the effects of hardware-conscious indexing strategies tailored for contemporary and emerging hardware platforms. Through rigorous experimentation on a real-world database environment using the industry-standard TPC-H benchmark, this research evaluates the performance implications of indexing techniques specifically designed to exploit parallelism, vectorization, and hardware-accelerated operations. By examining approaches such as cache-conscious B-Tree variants, SIMD-optimized hash indexes, and GPU-accelerated spatial indexing, the study provides valuable insights into the potential performance gains and trade-offs associated with these hardware-aware indexing methods. The findings reveal that hardware-conscious indexing strategies can significantly outperform their traditional counterparts, particularly in data-intensive workloads and large-scale database deployments. Our experiments show improvements ranging from 32.4% to 48.6% in query execution time, depending on the specific technique and hardware configuration. However, the study also highlights the complexity of implementing and tuning these techniques, as they often require intricate code optimizations and a deep understanding of the underlying hardware architecture. Additionally, this research explores the potential of machine learning-based indexing approaches, including reinforcement learning for index selection and neural network-based index advisors. While these techniques show promise, with performance improvements of up to 48.6% in certain scenarios, their effectiveness varies across different query types and data distributions. By offering a comprehensive analysis and practical recommendations, this research contributes to the ongoing pursuit of database performance optimization in the era of heterogeneous computing. The findings inform database administrators, developers, and system architects on effective indexing practices tailored for modern hardware, while also paving the way for future research into adaptive indexing techniques that can dynamically leverage hardware capabilities based on workload characteristics and resource availability
