- Mitigation of emergent bacterial pathogens using pseudomonas syringae pv. Actinidiae as a case study - from orchard to gene and everything in betweenPublication . Silva, Marta Nunes da; Santos, Miguel G.; Vasconcelos, Marta W.; Carvalho, Susana M. P.Globalization propelled human migration and commercial exchanges at the global level, but woefully led to the introduction of non-indigenous organisms into several agroecological systems. These include pathogenic bacteria with devastating consequences for numerous crops of agronomical importance for food production worldwide. In the last decade, research efforts have focused on these noxious organisms, aiming to understand their evolutionary processes, degree of pathogenicity, and mitigation strategies, which have allowed stakeholders and policymakers to develop evidence-based regulatory norms to improve management practices and minimize production losses. One of these cases is the bacterium Pseudomonas syringae pv. actinidiae (Psa), the causal agent of the kiwifruit bacterial canker, which has been causing drastic production losses and added costs related to orchard management in the kiwifruit industry. Although Psa is presently considered a pandemic pathogen and far from being eradicated, the implementation of strict regulatory norms and the efforts employed by the scientific community allowed the mitigation, to some extent, of its negative impacts through an integrated pest management approach. This included implementing directive guidelines, modifying cultural practices, and searching for sources of plant resistance. However, bacterial pathogens often have high spatial and temporal variability, with new strains constantly arising through mutation, recombination, and gene flow, posing constant pressure to agroecosystems. This review aims to critically appraise the efforts developed to mitigate bacterial pathogens of agronomical impact, from orchard management to genome analysis, using Psa as a case study, which could allow a prompter response against emerging pathogens in agroecosystems worldwide.
- Contribution of emotional competence to organisational change in a remote working settingPublication . Almeida, Tania; Ribeiro, Célia; Pereira, Paulo; Campos, Sofia; Ferreira, António; Passos, ClotildeIntroduction: Organisations are constantly facing change and, over the last months, the COVID-19 pandemic has introduced a set of cross-cutting changes that forced many employees to work from home. Objectives: Identify the emotional competencies that can be found in the different organisational change processes related to remote working and to identify the relationship between emotional competencies and resistance to organisational change. Methods: This descriptive, quantitative, correlational study was conducted with a sample of 115 workers from different business sectors Results: Showed a correlation between cognitive rigidity and emotional competence. It also became evident that emotional competencies have no influence whatsoever on the change management processes that take place in a remote working environment. Conclusion: The respondents showed low resistance to change and high emotional competence, which may have helped them adapt to this kind of work.
- Cibercrime & a problemática da prova ilicitamente obtida por particulares no processo penal portuguêsPublication . Pereira, Ana Filipa Nunes; Cunha, José Manuel Damião daA presente dissertação propõe uma análise aos problemas e consequências resultantes do surgimento da tecnologia e, principalmente, da internet, enquanto ferramentas impulsionadoras de uma nova realidade criminal. Com este estudo pretende-se uma reflexão não só relativa ao surgimento de novos tipos criminais ou de novas ferramentas do crime, fruto da criminalização de condutas lesivas levadas a cabo no ciberespaço, como de problemas que se levantam a nível processual, mais concretamente, das provas ilegalmente obtidas por particulares e a sua (in)admissibilidade no processo penal português.
- A violência sexual contra mulheres em situação de conflito armadoPublication . Gonçalves, Joana Maria Vieira da Silva; Tavares, Maria Isabel Cantista de CastroDurante séculos, e até hoje, as mulheres são umas das vítimas invisíveis dos conflitos armados. Sendo que, em virtude das raízes e conotação machista e patriarcal do contexto de guerra, a Violência Sexual é vista como uma consequência, quase que inevitável da mesma. Neste trabalho iremos analisar a evolução da legislação internacional, no que concerne a este assunto, nomeadamente quanto ao facto da mesma deixar de ser vista como uma mera consequência dos conflitos armados, para passar a ser reconhecida como Crime de Guerra, Crime Contra a Humanidade e Crime de Genocídio. Para tal, iremos interligar esta legislação com a sua aplicação prática, nomeadamente através da análise da Jurisprudência do Tribunal Penal Internacional para a Jugoslávia, Tribunal Penal Internacional para o Ruanda e Tribunal Penal Internacional, a qual constituiu uma importante forma de progresso quanto aos Direitos das Mulheres e ainda no que toca ao combate à impunidade dos agressores e violadores das normas de Direito Internacional, nesta matéria.
