Escutas telefónicas: dos conhecimentos da investigação aos conhecimentos fortuitos

As escutas telefónicas são hoje um importante instrumento no combate à criminalidade. A criminalidade organizada é hoje altamente sofisticada e sem o recurso a este meio, excepcional, de obtenção de prova os níveis de eficácia da investigação poderiam ficar verdadeiramente comprometidos. A sua utilização implica uma grande compressão de alguns dos direitos fundamentais, nomeadamente o direito à palavra, à intimidade da vida privada e a inviolabilidade das telecomunicações. Apesar desta danosidade, muitas vezes as escutas telefónicas são consideradas nulas por desrespeito a formalidades a que Órgãos de Policia Criminal (OPC) estão vinculados. Como consequência das escutas, surgem os conhecimentos fortuitos que nos últimos anos têm sido alvo de ambiguidades no que diz respeito à sua valoração.Telephone tapping is an important tool in today‟s fight against criminal activities. Nowadays organized crime is highly sophisticated and not resorting to this exceptional mean of obtaining proof may truly compromise the effectiveness of investigation. Using telephone tapping often implies conflict with some fundamental rights, namely, the right to free speech, the right to privacy and the inviolability of telecommunications. Along with this harmful repercussion, many times phone tapping is considered unlawful due to the disrespect for formalities that Criminal Police Organs are obligated to. As a consequence from using telephone tapping, fortuitous knowledge has been arose, which in the last few years, led to appraisal ambiguities

Analytics no Ensino Superior : métodos e ferramentas para apoio à gestão da atividade de ensino

As Instituições do Ensino Superior (IES) recebem hoje públicos heterogéneos e uma nova geração de estudantes imersos num quotidiano interligado pelo digital que esperam aprender em contextos mais flexíveis, suportados na tecnologia e no trabalho colaborativo. Pressionadas por este ambiente social, estas organizações procuram introduzir a inovação pela via da tecnologia, investido em sistemas tecnológicos na tentativa de dar respostas pedagógicas e organizacionais eficientes. Na presente investigação, partindo do contexto da Universidade Católica Portuguesa - Centro Regional do Porto (Católica-Porto), procurou-se aprofundar a compreensão do fenómeno da introdução da mudança e inovação pela via da tecnologia, nos campos pedagógico e organizacional, nas IES. Centrou-se a análise na gestão dos Ambientes de Aprendizagem Ricos em Tecnologia (TELE - Technology Enhanced Learning Environments) através dos sistemas de Analytics (Learning Analytics e Academic Analytics). A aproximação metodológica à problemática da gestão da atividade de ensino em TELE nas IES foi realizada com recurso a um modelo de duas etapas. A primeira etapa assume um cariz qualitativo e justifica-se pelos objetivos do estudo que são descritivos, na medida em que se pretendeu caracterizar o TELE da Católica-Porto na complexidade do contexto, relativamente às dimensões críticas de qualidade. Concomitantemente, esta fase do estudo teve uma tónica explicativa, pois, pretendeu-se identificar os fatores facilitadores e as condicionantes no uso e integração da tecnologia, em particular do Learning Content Management System (LCMS), na atividade formativa para enquadrar os resultados da segunda etapa da investigação. O design science foi a aproximação seguida na segunda etapa, em que se concebeu, desenvolveu e operacionalizou um sistema de Learning Analytics para aferição do grau de integração do LCMS (o subsistema tecnológico central no TELE da Católica-Porto) no processo de ensino e aprendizagem, com propósito de ser utilizado na gestão. Esta fase da investigação contemplou, também, o desenvolvimento de um segundo artefacto tecnológico – protótipo de Academic Analytics – para a gestão da atividade de ensino na instituição, que agrega dados já existentes em três subsistemas tecnológicos: LCMS, Serviços Administrativos (Sophia) e Sistema de Garantia Interna de Qualidade (SIGIQ). Os resultados indicam que a Católica-Porto tem dado passos na construção de um TELE. Contudo a integração do LCMS, a plataforma tecnológica de uso institucionalizado e mais generalizado, ainda está muito aquém das reais potencialidades que oferece. O estudo também demonstrou que os sistemas de Learning Analytics e Academic Analytics têm elevado potencial para a gestão da atividade de ensino. Deste trabalho resultam como principais contributos teórico-práticos: i) sistematização do conhecimento sobre principais dimensões que condicionam a qualidade do TELE e a sua gestão; ii) sistematização do estado da arte na temática do Analytics em educação e as potencialidades e dificuldades do seu uso na prática; iii) desenvolvimento de dois sistemas de Analytics para gestão da atividade de ensino.Nowadays, Higher Education Institutions (HEIs) receive heterogeneous public and a new generation of students immersed in a daily life which is digitally interconnected and who expect to learn in more flexible environments, supported by technology and collaborative work. Pressured by this social environment, these organizations seek to introduce innovation via technology, and they invest in technological systems in an attempt to give effective pedagogical and organizational responses. In the present study, based on the context of the Universidade Católica Portuguesa - Centro Regional do Porto (Católica-Porto), we sought to deepen the understanding of the phenomenon of introducing change and innovation in HEIs by means of technology in the pedagogical and organizational fields. The study was focused on the analysis of the management of Technology Enhanced Learning Environments (TELE) through systems of Analytics (Learning Analytics e Academic Analytics). A methodological approach to the problem of managing teaching in TELE in HEIs was carried out by using a two-step model. The first step has a qualitative nature and is justified by the objectives of the study which are descriptive, as we intended to characterize Católica-Porto’s TELE on the complexity of the context, as far as the quality of critical dimensions is concerned. Concomitantly, this phase of the study had an explanatory emphasis, as we tried to identify the facilitating factors and the constraints in the use and integration of technology, particularly the Learning Content Management System (LCMS), in the teaching activity, in order to contextualize the results of the second stage of the study. The design science was the approach followed in the second stage, in which a system of Learning Analytics was developed and operationalized to measure the degree of integration of the LCMS (the central technological subsystem in Católica-Porto’s TELE) in the teaching and learning process, with the purpose to be used in management. This phase of research also included the development of a second technological artifact – a prototype of Academic Analytics – for the management of the teaching activities at the institution, which aggregates data that already exists on three technological subsystems: LCMS, Administrative Services (Sophia) and Services of Quality Management (SIGIQ). The results indicate that Católica-Porto has taken steps in building a TELE. However the integration of the LCMS, the technological platform of institutionalized and widespread use, is still far behind the true potential it offers. The study also showed that the systems of Learning Analytics and Academic Analytics have high potential for the management of the teaching activity. The main theoretical and practical contributions of this study are: i) systematization of knowledge about key dimensions that affect the quality of TELE and its management; ii) systematization of the state of the art on the topic of Analytics in education and the strengths and difficulties of its use in practice; iii) development of two systems of Analytics for managing the teaching activity

USO DE MÍDIAS SOCIAIS POR ESTUDANTES DE ENSINO MÉDIO DE LIMEIRA-SP

No artigo apresentam-se informações sobre a utilização da internet e das redes sociais por estudantes de terceiro ano de ensino médio de duas escolas (uma pública, outra privada) de Limeira-SP, como recorte de uma investigação sobre as expectativas desses jovens em relação ao ensino superior nos anos de 2018 e 2019. A pesquisa se desenvolveu por meio da aplicação de questionários socioeconômicos e entrevistas semi-estruturadas. As condições de acesso à internet eram similares para ambos os grupos, mas havia distinções fundamentais em relação ao uso desses recursos. Para os estudantes da escola privada, essas ferramentas mostraram-se importantes para a aquisição de conhecimentos e informações relevantes para o ingresso no ensino superior. Aos jovens da escola pública, por sua vez, esses recursos mostraram-se importantes para obter informações básicas sobre os processos seletivos e as políticas de ação afirmativa

as estruturas claustrais no registo arqueológico

UIDB/04666/2020 UIDP/04666/2020Fundado em 1492, o Hospital Real de Todos-os-Santos revelou-se paradigmático em Portugal no que à assistência diz respeito. Inovador nos mais diversos campos merece especial atenção a inspiração arquitetónica renascentista, que se traduziu em novos hábitos no quotidiano hospitalar. De planta cruciforme e integrando quatro pátios, a água esteve presente através de, pelo menos, quatro estruturas hidráulicas/poços, cada uma afecta a um claustro e, consequentemente, às suas dependências térreas, no decorrer dos quase três séculos de funcionamento deste grande complexo público. Este texto analisa as estruturas hidráulicas do Hospital Real de Todos-os-Santos descobertas aquando das intervenções arqueológicas na Praça da Figueira na década de 60 e em 1999-2001, integradas nos vários momentos de reformulação arquitetónica do edifício, estudados no âmbito do projeto «Hospital Real de Todos-os-Santos: a Cidade e a Saúde». Além de elemento vital para o seu funcionamento, estas estruturas são um espelho de hábitos e atribuições funcionais dos espaços envolventes.publishersversionpublishe

Population structure of Gobiidae in a tropical urban estuary

As spatiotemporal variations in estuaries affect the population structure of species, the study aimed to analyze the distribution of species of the family Gobiidae in the Capibaribe River's estuary city of Recife (northeastern Brazil). Sampling was performed bi-monthly from February 2009 to December 2012 at two sampling stations. The weight-length relationship of the species was determined using potential regression analysis. Density and biomass values were determined for each species per sampling station and season. The Mann-Whitney test was used to compare spatial and seasonal differences in abundance. A non-metric multidimensional scaling ordination was used to assess changes in species composition. Seven hundred eighty-eight individuals were caught. The most representative species of Gobiidae was Ctenogobius boleosoma, followed by Evorthodus lyricus and Gobionellus oceanicus. The relationship between total weight (TW) and standard length (SL) was potential and significant for both C. boleosoma (TW = 0.04SL2.1815) and E. lyricus (TW = 0.0272SL2.795), and both exhibited negative allometric growth. The analysis of the main species' spatial variation demonstrated a significant difference in the number of individuals for C. boleosoma (U = 528; p = 0.000005) and E. lyricus (U = 312; p = 0.000000). No significant difference in abundance was found between the dry and rainy season for either C. boleosoma (U = 1052.2; p = 0.4659) or E. lyricus (U = 1054; p = 0.4726). The two most abundant species have similar habits and customarily inhabit stressful environments. Ctenogobius boleosoma and E. lyricus are residents of the Capibaribe River's estuary, and both move to regions near the outfall of the river in the rainy season

Dermatological side effects of cancer treatment: psychosocial implications—a systematic review of the literature

https://v2.sherpa.ac.uk/id/publication/24801Cancer is a leading cause of mortality and morbidity all over the world and the second major cause of death in Portugal. Dermatological side effects resulting from cancer treatment have a psychosocial impact on patients’ lives, such as quality of life (QoL), body image, cognitive fusion and social inhibition. This systematic review aimed to explore and synthesize the psychosocial impact of dermatological side effects of cancer treatment, answering the following research objectives: (i) Do the dermatological side effects of the cancer treatment present any psychosocial impact for the patients? (ii) How does the psychosocial impact of the dermatological toxicities of the cancer treatment manifest in patients’ lives? Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed and guided a systematic search through the PubMed, Cochrane Library and PyscNet databases. The considered studies correlate dermatological side effects of cancer treatments and their psychological/psychosocial outcomes. The studies found were all published in peer-reviewed journals. The results obtained established that cancer treatment causes the most varied skin changes, consequently reducing self-esteem and QoL; disturbing body image; and contributing to cases of stress, depression and anxiety. There is still limited literature that profoundly investigates the experience of living with these skin toxicities. The development of research lines to improve knowledge in this field will allow for significant improvements in healthcare for patients undergoing cancer treatment who need to focus more on the psychosocial implications of skin toxicities. The novelty of this review lies in adding knowledge summarizing the psychosocial implications of dermatological side effects of cancer treatment to support healthcare providers in the development of integrative therapeutic strategies for these patients in their clinical practice.info:eu-repo/semantics/publishedVersio

Characterization of split cylinder airlift photobioreactors for efficient microalgae cultivation

An extensive characterization of photobioreactors (PBRs) must be made in order to optimize their operational conditions, operate design improvements and perform scale-up. In this work, a hydrodynamic characterization of liquid and gas phases was performed, as well as the determination of the mass transfer coefficient of three different PBRs (bubble column – BC – and two Split Cylinder Airlift Photobioreactors – SCAPBRs – featuring two different riser-to-downcomer cross sectional area ratios: SCAPBR 75 and SCAPBR 50). The effect of these parameters on biomass productivity was also evaluated. The developed SCAPBRs proved to be extremely suitable for microalgae cultivation. The design of the PBR, particularly the designed gas sparger, allowed meeting the needs of microalgae in terms of mixing and mass transfer (efficient supply and removal of CO2 and O2, respectively). SCAPBR 50 (with a superficial gas velocity of 0.0044 m s−1) showed, among the tested PBRs, the highest value of biomass volumetric productivity (0.75 g L−1 d−1). This result is probably due to a higher PBR illuminated surface area, and a more regular flow pattern between the illuminated and dark zones verified in SCAPBR 50, which allows exposing cells to regular light–dark periods.This research work was supported by the Grant SFRH/BPD/98694/2013 (Bruno Fernandes) from Fundacao para a Ciencia e a Tecnologia (Portugal).

Phosphatase activity of H+-ATPase from chloroplasts

AbstractThe chloroplast H+-ATPase (CF0F1) was purified from spinach chloroplasts and studied both in the soluble state and after reconstitution into asolectin liposomes. Hydrolysis of ATP and of p-nitrophenylphosphate (p-NPP) catalysed by CF0F1 was investigated. (1) Soluble, isolated CF0F1 catalyzes ATP hydrolysis and p-NPP hydrolysis. (2) ATP inhibits the phosphatase activity in the latent state (Ki=1.7 mM). (3) Addition of 100 mM sulfite increases the rate of ATP hydrolysis by a factor of 10, while p-NPP hydrolysis is completely abolished. (4) CF0F1 reconstituted into asolectin vesicles catalyzes ATP hydrolysis and p-NPP hydrolysis. When the enzyme is brought into its active state by a ΔpH/Δϕ jump, ATP hydrolysis is increased by a factor of 8, and p-NPP hydrolysis is completely abolished. (5) ATP hydrolysis by the activated enzyme is inhibited by p-NPP (Ki=1.6 mM). (6) p-NPP also inhibits ATP synthesis by the activated enzyme, competing with phosphate (Ki=0.9 mM). These results show that in the active state of CF0F1, p-NPP is not hydrolyzed but acts as a competitive inhibitor; in the inactive state of CF0F1, p-NPP is hydrolyzed. Hydrolysis of p-NPP might be used as an assay for the inactive forms of CF0F1
