Perspectivas Emergentes: Um Panorama Sobre Mídias Alternativas Digitais e Pessoas Migrantes e/ou Racializadas em Portugal
No full textAs mídias alternativas digitais fazem parte de um movimento efervescente de criação de órgãos de comunicação social, oferecendo uma contrapartida importante diante da tendência de concentração da produção da informação em alguns conglomerados institucionais. Em Portugal, apesar dessas mídias terem ganhado destaque na academia, ainda são poucos os estudos que abordam a questão a partir do recorte das pessoas migrantes e/ou racializadas. De modo a preencher essa lacuna e a oferecer um panorama aprofundado do ecossistema midiático alternativo digital em Portugal no que toca esses grupos sociais, este artigo apresenta discussões norteadas por análises feitas a partir de um mapeamento de mídias alternativas digitais relacionadas com as migrações e/ou pessoas racializadas. São abordados diferentes aspectos, como a relação entre a sua fundação e os contextos históricos e sociais em Portugal ao longo das últimas décadas, as implicações da operação com equipes reduzidas e as problemáticas associadas à adoção de diferentes estratégias de financiamento. Como resultado, desenvolve-se uma problematização necessária de questões prementes que contribuem para o debate acerca do papel e importância da participação desta franja da população nas mídias em Portugal, de forma a fomentar um ecossistema midiático mais inclusivo, heterogêneo e representativo da diversidade social e cultural do país.Alternative digital media form part of an effervescent movement to create media organisations, offering an important counterpart to the tendency to concentrate information production within a few institutional conglomerates. In Portugal, while these media outlets have gained prominence in academia, there are still few studies addressing the issue from the perspective of migrants and/or racialised people. In order to address this gap and provide an in-depth overview of the digital alternative media ecosystem in Portugal concerning these social groups, this article presents discussions informed by analyses based on a mapping of digital alternative media related to migration and/or racialised people. Various aspects are examined, such as the relationship between their foundation and the historical and social contexts in Portugal over the last few decades, the challenges of operating with small teams, and the problems associated with adopting different funding strategies. Thus, this analysis contributes to a critical discussion of pressing issues that shape the debate on the role and significance of the participation of this underrepresented group of the population in the media in Portugal. The goal is to foster a more inclusive, diverse and representative media ecosystem that reflects the country's social and cultural diversity. It offers a critical examination of the role and significance of involving this segment of the population in the media in Portugal, aiming to promote a media ecosystem that is more inclusive, diverse, and representative of the country's social and cultural diversity
Metaverse adoption for the teaching and learning of project management: an exploratory study of student use
No full textThe rapid adoption of collaboration technologies over the course of the COVID-19 pandemic, combined with the advancement, growth, and proliferation of metaverse technology capabilities, has created a heightened awareness and comfort with the use of advanced collaboration technologies for online and distance education. This paper presents an exploratory study of how metaverse technologies can be adopted for the teaching and learning of project management concepts and skills specifically, as metaverses have been identified as a legitimate tool for the support of virtual projects. As a part of this work, a task was designed and adopted in an undergraduate project management course. Study results related to the teaching and learning of project management as well as student perceptions of metaverse technology adoption show that students were able to work together in a metaverse environment and collaborate with one another to achieve group consensus on a task. Ultimately, the findings from this case can guide future adoptions of metaverse technologies both in and out of the classroom
Spend analytics in Norwegian public procurement: adoption status and influencing factors
No full textPublic procurement is an essential government function representing a substantial part of a nation’s economy. How decisions are made in public procurement influences nations' economic health and citizens' daily lives. In this study, we employ the technology–organization–environment (TOE) framework to investigate public procurement officials' adoption of spend analytics in Norway. Based on an analysis of survey data from 529 Norwegian procurement entities collected by the Norwegian Agency for Public and Financial Management, we find that 61% do not utilize spend analytics, with adoption rates varying across different types of entities. A correlation analysis indicates that procurement analysis competencies are significantly associated with higher adoption rates, highlighting the critical role of analytical skills. Organizational factors such as procurement volume and a centralized purchasing unit are positively linked to the use of spend analytics. Environmental factors offer a contrasting picture: while specific factors seem to drive spending analytics adoption, a strong orientation towards sustainability and competency challenges may hinder it. These findings encourage a systemic look at how the public procurement system could be more data-driven
Propriedades de betão drenante em misturas com agregados reciclados
No full textRigid pavement materials with draining concrete, after construction, undergo a degradation process under the action of traffic and weather conditions. This process, which occurs during the life of the floor, can be slower if it is well constructed and maintained. Thus, it is essential that the mechanical characterization of the concrete is suitable for its application. Thus, workability and density tests must be carried out in relation to fresh concrete. In the case of hardened concrete, these are compressive and flexural strength tests, permeability tests and wear resistance tests. Pervious concrete can be a successful safety solution for heavy rains and increasingly frequent floods. This study focused on obtaining an optimized pervious concrete, within the scope of international standards, through the analysis of concrete made with the same W/C ratios and vibration times and different percentages of recycled aggregate. The results show the strong influence of both parameters on porosity and permeability distribution and the negative influence of higher porosities on strength. Concrete with a W/C ratio of 0.30 and a vibration time of 40 seconds and 20% recycled aggregate was selected for its superior mechanical performance.Os materiais de pavimento rígido com betão drenante, após sua construção, sofrem um processo de degradação sob a ação do tráfego e das condições climáticas. Esse processo, que ocorre durante a vida útil do piso, pode ser mais lento se for bem construído e mantido. Assim, é fundamental que a caracterização mecânica do betão seja adequada para a sua aplicação. Assim, os ensaios de trabalhabilidade e densidade devem ser realizados em relação ao betão fresco. No caso do betão endurecido, são os ensaios de resistência à compressão e flexão, os ensaios de permeabilidade e os ensaios de resistência ao desgaste. O betão permeável pode ser uma solução de segurança bem-sucedida para chuvas fortes e inundações cada vez mais frequentes. Este estudo teve como foco a obtenção de um betão permeável otimizado, dentro do escopo das normas internacionais, por meio da análise do betão feitos com as mesmas relações A/C e tempos de vibração e os diferentes percentuais de agregado reciclado. Os resultados mostram a forte influência de ambos os parâmetros sobre a distribuição de porosidade e permeabilidade e a influência negativa de porosidades mais altas sobre a resistência. O betão com relação de 0,30 W/C e tempo de vibração de 40 segundos e 20% de agregado reciclado foi selecionado por seu desempenho mecânico superior
Breaking Boundaries in Malaria Research: Design of a Genetic Tool for High-Throughput Gametocidal Drug Screening
No full textMalaria, a devastating illness remains a global health concern with an estimated 249 million malaria cases in 85 malaria-endemic countries around the world. Malaria elimination, challenged by drug resistance, requires strategic interventions that could be the implementation of antimalarials with selective actions on the different phases of the parasite life cycle. Of particular relevance is gametocytocidal drugs that could be used to prevent transmission of malaria infection to the mosquito.
Finding drugs with gametocidal effect thus are limited by the technical challenges of large-scale production and quantification of parasite transmission stage, gametocytes. To surmount these obstacles, our study endeavors to design a genetic engineering strategy (a vector construct) to further deliver nucleic acid information through transfections-based systems in the form of a plasmid into Plasmodium falciparum. This approach will enable us to engineer a transgenic parasite line for multi-stage drug screening, targeting the symptomatic intra-erythrocyte parasite stage and gametocytes.
Genetic engineering tools such as selected linked integration system and attB-attP site-specific recombination will be used in our vector construct aiming the genetic integration process into the P. falciparum genome. These systems will accommodate strategies for easy and accurate stage-specific quantification such as RFP-luciferase fusion cloned downstream stage-specific promoters leading to reporter products with optical outputs and for efficient production of gametocytes at large scale using a riboswitch-based inducible gene expression system. Such technology is of major need and will pave the way for scaling up the capacity for high-throughput drug screening, leading to improved strategies to find drugs capable of blocking malaria transmission
Direito e Literatura - Contributos sobre Justiça à luz de O Processo, de Kafka
No full textThis article proposes an interdisciplinary analysis between law and literature, exploring the threefold perspective of law as technique, science, and art. We focus on Franz Kafka’s The Trial to examine the underlying legal meaning within the narrative. The study highlights the importance of literature in understanding law, involving legislative issues, narratology and legal interpretation. In this context, we address literature’s significant contribution to enhancing the critical thinking and analytical capacity of legal professionals regarding legal realities. The article is structured into five chapters, starting with a synthesis of Kafka’s work and an analysis of its legal significance, followed by preliminary issues, and concluding with a reflection on legal-philosophical themes such as the status of the defendant, the paradox of freedom, and the sense of justice. This interdisciplinary approach aims to contribute to a broader understanding of law by integrating literary elements, expanding the traditional boundaries of knowledge and legal interpretation.Este artigo propõe uma análise interdisciplinar entre direito e literatura, explorando a tríplice perspetiva do Direito como técnica, ciência e arte. Focamo-nos na obra O Processo, de Franz Kafka, para examinar o significado jurídico subjacente à narrativa. O estudo destaca a importância da literatura na compreensão do Direito, envolvendo questões legislativas, narratologia e interpretação jurídica. Nestes termos, abordaremos a importante contribuição da literatura para o aprimoramento do sentido crítico do jurista e da sua capacidade analítica em relação à realidade jurídica. O artigo está estruturado em cinco capítulos, começando por uma síntese da obra de Kafka e uma análise do seu significado jurídico, seguido de questões prévias e, por fim, uma reflexão sobre temas jurídico-filosóficos, como o estatuto de arguido/acusado, o paradoxo da liberdade e o sentido de justiça. Esta abordagem interdisciplinar procura contribuir para a compreensão do Direito ao integrar elementos literários, ampliando as fronteiras tradicionais do conhecimento e da interpretação jurídica
Diversidade religiosa e discriminação indireta em contexto laboral: o que nos diz a prática dos tribunais?
No full textLa visibilité croissante de la religion sur le lieu de travail est à l’origine de nombreux foyers de tension et de litiges en Europe et a fait l’objet d’une certaine attention médiatique, notamment lorsque les tribunaux sont appelés à intervenir. Dans la plupart des cas, il ne s’agit pas tant d’une discrimination directe à l’encontre des employés en raison de leur religion, mais d’une discrimination indirecte résultant de l’application à tous les employés de règles « neutres », qui rendent particulièrement difficile la capacité des personnes appartenant à des minorités religieuses de concilier devoirs professionnels et devoirs religieux. Dans ce texte, nous faisons un tour d’horizon des décisions des tribunaux étatiques et internationaux en la matière et discutons des implications de ces prises de position.A crescente visibilidade da religião no local de trabalho está na origem de não poucos focos de tensão e litígio na Europa e tem merecido alguma atenção mediática, sobretudo quando os tribunais são chamados a intervir. Na maioria dos casos, não se trata tanto de discriminação direta contra trabalhadores por causa da sua religião, mas de discriminação indireta resultante da aplicação a todos os trabalhadores de regras “neutras”, que tornam particularmente difícil para as pessoas pertencentes a minorias religiosas a conciliação entre deveres profissionais e deveres religiosos. Neste texto, fazemos um apanhado de decisões de tribunais estatais e internacionais sobre a matéria e discutimos as implicações dessas pronúncias.The growing visibility of religion in the workplace has been the source of tension and conflict in Europe and has garnered some media attention, particularly when courts are called in to solve disputes. In most cases, the issue is not so much direct discrimination against workers due to their religion, but instead indirect discrimination arising from the application of “neutral” rules to all workers, which make it particularly difficult for individuals belonging to religious minorities to reconcile their professional and religious obligations. In this article, we map out leading cases from international and domestic courts, and discuss the significance of those rulings
