O Relatório descreverá um conjunto de actividades que apostaram em envolver a escola, os alunos e suas famílias, com a Casa das Histórias Paula Rego, através do contacto com as obras de arte – plásticas e arquitectónica - numa experiência única e marcante. O Relatório apresentará, pormenorizadamente, todas as fases da prática docente, desde a concepção do projecto e suas motivações, até à concretização das acções. O Relatório será concluído com as últimas reflexões e comentários dos participantes do projecto.

Este relatório baseia-se em duas vagas de inquérito online sobre a pandemia Covid19 e os seus impactos nas pessoas que vivem em Portugal. O inquérito decorreu entre os dias 25 e 29 de março de 2020 (primeira vaga) e entre os dias 24 de abril e 4 de maio do mesmo ano (segunda vaga), junto de uma amostra de 752 inquiridos que responderam às duas vagas. A amostra não é representativa da população residente em Portugal. Por essa razão, este relatório não procura fazer inferências descritivas para qualquer população, mas sim concentrar-se em três aspetos principais: 1) as evoluções ocorridas no período que medeia entre a primeira e a segunda vagas do inquérito; 2) a relação entre as respostas dadas nas duas vagas e diferentes atributos dos inquiridos; e 3) o discurso direto dos inquiridos em relação a algumas perguntas de resposta aberta incluídas no inquérito.

O objectivo da Newsletter do Instituto de Saúde Baseado na Evidência (ISBE) é a disponibilização de informação sobre áreas relevantes para a prática clínica, baseada na melhor evidência científica. São localizados estudos relevantes e de alta qualidade, criticamente avaliados pela sua validade, importância dos resultados e aplicabilidade prática e resumidos numa óptica de suporte à decisão clínica. É dada prioridade aos estudos de causalidade – revisões sistemáticas, ensaios clínicos, estudos de coorte prospectivos/retrospectivos, estudos seccionais cruzados e caso‐controlo – incluindo‐se ainda, quando justificado, estudos qualitativos considerados de elevada qualidade metodológica e importância clínica.

The transformation of decayed semi-peripheral riverside areas and its Tangible Culture Heritage is presented today as a contributing factor in urban regeneration by several public preservation bodies and agendas, as well as privately led investment. These practices demand the economic and symbolic valorization of abandoned Tangible Cultural Heritage, where the social coexistence of residents, workers and visitors is seen as a smoother urban integration of these deprived territories and their communities into the surrounding contemporary cities. We’ll focus our approach on socio-spatial changes occurring in Marvila and Beato, presented today as new urban areas in which to financially invest after the 2011 economic crisis occurred in Portugal, discussing public and private re- appropriation of Old Palaces, Convents and Farms and Reconverted Warehouses (industrial and commercial); towards the creation of a new urban centrality in Lisbon. In this case, public ground-field intervention established a culture led regeneration process, with the creation of a municipal library, a crucial point in the cultural use of this space, community participation and gathering. Dealing with private investors, despite the positive effects, such as a reduction in unemployment, economic diversification and re-use of urban voids, there is always the possibility of undesired consequences. This paper argues, and the research experiments in many European cities show us that the ambition to improve the image of these deprived areas, despite somGonzalex encouraging ground level achievements, has unwanted or unexpected outcomes, starting as urban regeneration practices, often sliding towards gentrification, where local public powers have a determinant role.

Populism is one of the most contested political ideas of the modern age. It has also become a key concept in the social sciences, especially in the last few decades. Both as a polemic and as a concept, populism has accompanied democratic politics since at least the late nineteenth-century. The current “populist revolt” suggests this embryonic relationship between populism and democracy is here to stay. In this article, we offer a summative account of populism, including why it is centrally oriented towards the figure of the sovereign people, as well as a discussion the most relevant approaches and a general assessment of this crucial topic. We conclude with a brief consideration of the challenges the current populist wave poses to democracy.

Introduction: Caregivers play a major role in providing all the support and care in daily activities for their relatives with dementia. To fully describe the influence of dementia caregiving on family caregivers’ life, we conducted a systematic review including caregivers’ perceptions about the positive and negative aspects of caring and the expressed factors. Materials and methods: We conducted a systematic review including articles from January 1998 to July 2020. Qualitative studies reporting family caregivers’ perceptions about their experiences and the effects/impact of dementia caregiving were eligible. Two authors extracted the data independently, and the analysis focused on the positive and negative aspects of dementia caregiving in caregivers’ life. Results: Eighty-one studies with 3347 participants were included in this review. The positive aspects of caregiving in caregivers’ life encompass personal accomplishment and strengthening relationships, which were enhanced by good medical counselling/formal care support and family/friends support. The negative aspects included emotional and social aspects experienced by caregivers. Other factors such as inappropriate medical/formal care support, illness progression and the costs of dementia contributed to negative appraisal. Discussion and implications: The findings provide insights into the holistic experience of caring for a person with dementia revelling the major positive and negative aspects underlying the caregiver role. The evidence emphasises the need ‘to focus on positive aspects’ and targeted interventions aimed at reducing the negative impact of caregiving, which has serious consequences on caregivers’ quality of life. A multicomplex intervention for dementia informal caregiving should be developed, committing the society to promote mental health, address these community needs and improve the quality of life of the person with dementia and their family caregivers.

No ano de 2018 publicamos a primeira obra dedicada à iluminação da Casa Real, onde disponibilizamos documentação referente às obras, à encomenda de projetos de arquitetura e à aquisição de luminária pela rainha D. Maria Pia para o seu Chalet do Estoril. Nesse mesmo ano tivemos acesso ao interior do edifício onde verificamos a possível colocação das peças para iluminação. Suposição corroborada pelo cotejamento com o Inventário do Real Chalet Estoril, que nos permitiu entender como estas peças foram criteriosamente escolhidas para uma determinada decoração. São estas novas reflexões e a realização de duas plantas dos pisos principais, ao tempo da monarquia, que aqui damos a conhecer.

No final do século XVIII desenvolveram-se novos meios de iluminação aperfeiçoados ao longo do XIX. A intensidade de luz alcançada era superior às tradicionais fontes e rapidamente proliferaram e facilitaram a vida quotidiana. No mesmo período, coincidiram experiências em torno da impressão gráfica e da fotografia. Estes registos imediatamente se tornaram essenciais para a propaganda, ensino e disseminação de cultura. A crescente procura possibilitou custos reduzidos na sua produção e estas formas de comunicar foram habilmente utilizadas pela emergente indústria de luminária na conceção de recibos e de catálogos. A França foi o país percursor na utilização destes meios para evidenciar os candeeiros, cuja combinação possibilitou a criação de um grafismo muito próprio, necessário para promover e vender os artigos, influenciando assim outros países europeus. Todavia nestes enveredou-se por outras formas gráficas e que refletem a sua própria cultura.

No ano de 1844 a Rainha D. Maria II ordenou a remodelação interior do setecentista Paço das Necessidades, em Lisboa, de acordo com o gosto eclético então em voga. No ano de 1854, após a sua morte, dá-se início ao arrolamento dos seus bens, no referido palácio, e são mencionados diversos candeeiros. Estes têm vindo a ser identificados por nós em vária documentação e nos acervos dos palácios nacionais, cujo estudo é aqui apresentado pela primeira vez.

This year saw a continuation of the trend of democratic erosion in the country. The Patriotic Front (PF) government, headed by President Edgar Lungu, used selected laws and regulations to demobilise critical voices and institutions. The Constitution Amendment Bill aroused fierce contestation, with several sections of civil society claiming that it undermined basic democratic principles and urging the government to withdraw it. A series of by-elections triggered violence between the PF and the major opposition party, the United Party for National Development (UPND). Incumbent and opposition parties faced increased intra-party polarisation. China played a key role in financing the country’s largest infrastructure projects despite mounting resentment against the country. New accords were signed with Russia, India, and Japan. Zambia opened a consulate in Dubai. The economy grew by only 2% due to the severe droughts which impacted electricity generation, agriculture production, mining outputs, and other sectors of activity. The IMF paid visits to the country and warned about the need for reduced external borrowing and sustained fiscal adjustment in order to improve macroeconomic performance.

Introduction: Emerging evidence points to an association between severe clinical presentation of COVID-19 and increased risk of thromboembolism. One-third of patients hospitalized due to severe COVID-19 develops macrovascular thrombotic complications, including venous thromboembolism, myocardial injury/infarction and stroke. Concurrently, the autopsy series indicate multiorgan damage pattern consistent with microvascular injury. Prophylaxis, diagnosis and treatment: COVID-19 associated coagulopathy has distinct features, including markedly elevated D-dimers concentration with nearly normal activated partial thromboplastin time, prothrombin time and platelet count. The diagnosis may be challenging due to overlapping features between pulmonary embolism and severe COVID-19 disease, such as dyspnoea, high concentration of D-dimers, right ventricle with dysfunction or enlargement, and acute respiratory distress syndrome. Both macro- and microvascular complications are associated with an increased risk of in-hospital mortality. Therefore, early recognition of coagulation abnormalities among hospitalized COVID-19 patients are critical measures to identify patients with poor prognosis, guide antithrombotic prophylaxis or treatment, and improve patients' clinical outcomes. Recommendations for clinicians: Most of the guidelines and consensus documents published on behalf of professional societies focused on thrombosis and hemostasis advocate the use of anticoagulants in all patients hospitalized with COVID-19, as well as 2-6 weeks post hospital discharge in the absence of contraindications. However, since there is no guidance for deciding the intensity and duration of anticoagulation, the decision-making process should be made in individual-case basis. Conclusions: Here, we review the mechanistic relationships between inflammation and thrombosis, discuss the macrovascular and microvascular complications and summarize the prophylaxis, diagnosis and treatment of thromboembolism in patients affected by COVID-19.

The global or planetary reach of gentrification has become a mainstream in critical urban studies. And yet, the ‘travels’ of a concept originated in specific places and times have often brought about a loss of explanatory and strategic power. In this article, we argue that another concept, that of articulation developed by Laclau and Mouffe, is particularly adequate to help gentrification, touristification and financialisation to travel among places and levels of abstraction. In order to make this argument, we focus on Southern Europe, whose cities had long been considered scarcely gentrifiable and where, more recently, critical urban scholarship has made large use ogf gentrification, touristification and financialisation to explain the impacts of crisis, austerity, and afterwards economic rebound driven by real estate and tourism. We explore in multi-scalar perspective the trajectory of Mouraria, a historical neighbourhood in Lisbon – and particularly the dimensions of housing and local politics. We show how Mouraria, during the last decade, shifted from being a ‘deviant’ case – capable of taking advantage of neoliberal regeneration policies in order to keep its social diversity and most of its long-term residents – toward one ‘paradigmatic’ of urbanisation-as-accumulation and contentious urban politics. We explain this shift by focusing on its multi-scalar determinants; concluding that present urban change in many Southern European cities should be understood as the articulation of various processes, which include gentrification, touristification and financialisation.

When do presidents delegate policy-making authority to their foreign ministries? And is foreign policy unique in this respect? We posit that six international, national, and personal factors determine the opportunity and motivation of presidents to delegate, and then analyse the cases of Argentina, Brazil, and Mexico in 1946–2015. By applying fuzzy-set qualitative comparative analysis, we find that four combinations of factors are sufficient paths to delegation: (1) international stability and elite consensus on foreign policy; (2) international stability, right-wing president, and low diplomatic professionalisation; (3) international stability, right-wing president, and low presidential expertise on foreign policy; or (4) absence of authoritarianism combined with elite consensus on foreign policy and right-wing president. Our study of foreign ministries reinforces some of the main findings of the scholarly literature on other ministries, thus challenging the view of foreign policy-making as different from domestic policy areas.

A forma de produção, distribuição e consumo de notícias tem atravessado sérias mudanças ao longo dos últimos anos, suscitadas, entre outros fatores, pela introdução de tecnologias digitais na esfera da comunicação social. Este capítulo pretende contribuir para o debate em torno desta questão, centrando- se nas implicações deste processo na condição social dos jornalistas. Partindo da análise de anúncios de emprego, os objetivos são compreender o tipo da empresa requerente; as principais características da oferta de trabalho (o meio de comunicação ou a área temática, a título de exemplo); as condições oferecidas (contratuais, salariais, etc.); e o perfil do jornalista solicitado (qualificações e competências).

Os estudos desenvolvidos nos capítulos anteriores procuram contribuir para dar resposta às questões de fundo da investigação que organiza este livro: como está o jornalismo a ser afetado pelo processo de hegemonia digital dos media e como considerá-lo neste quadro como entidade cultural das sociedades democráticas? Que instituições, normas, processos e atores têm vindo a produzir-se no jornalismo e na informação e que fatores estão a formá-los? De que modo é que as novas instituições de media, com as suas estruturas de recursos, prescrições e atores, estão a moldar as expectativas e práticas de produtores e consumidores de media? Como abordar o jornalismo português na sua relação com o processo em curso de hegemonia digital? O objetivo é concorrer para o entendimento refl exivo das consequências da viragem digital e neoliberal nos media e no jornalismo.

Os processos de globalização e digitalização têm interpelado, desafi ado e modifi cado o lugar e o entendimento de cultura no jornalismo, as lógicas de produção e receção de informação e as fontes de reputação profi ssional. O estudo destas alterações ganha relevância também pela centralidade dos intermediários culturais nos projetos editoriais, proporcionando a compreensão da complexidade do trabalho cultural na economia do conhecimento, cada vez mais uma economia digital baseada em freelancing (Capelli e Keller, 2013). O estudo da Artecapital, a partir de análise documental e na realização de entrevistas1, demonstra, com as suas especifi cidades, as viragens que o processo de digitalização tem suscitado na organização do jornalismo cultural e da crítica de artes. O texto caracteriza a revista eletrónica, publicada desde 2006, em quatro partes: a primeira incide na génese do projeto editorial; a segunda foca a sua estrutura organizativa; a terceira analisa o formato editorial; a quarta centra-se nos produtores dos textos. A conclusão sistematiza o que mais confere signifi cado à Artecapital, avançando-se uma síntese inicial. Viabilizada pela economia de custos do suporte digital, a revista inspira-se nos géneros jornalísticos convencionais, desenvolve possibilidades das novas tecnologias, como a curadoria informacional. Orientada por uma equipa minimal, a plataforma suporta a sua longevidade num conjunto constantemente renovado de colaboradores, que entregam e expõem a escrita e a reflexão sobre arte e cultura em nome da autoexpressão e procura de visibilidade.

Background: Myriads of signaling pathways in a single cell function to achieve the highest spatio-temporal integration. Data are accumulating on the role of electromechanical soliton-like waves in signal transduction processes. Theoretical studies strongly suggest feasibility of both classical and quantum computing involving microtubules. Aim: A theoretical study of the role of the complex composed of the plasma membrane and the microtubule-based cytoskeleton as a system that transmits, stores and processes information. Methods: Theoretical analysis presented here refers to (i) the Penrose–Hameroff theory of consciousness (Orchestrated Objective Reduction; Orch OR), (ii) the description of the centrosome as a reference system for construction of the 3D map of the cell proposed by Regolini, (iii) the Heimburg–Jackson model of the nerve pulse propagation along axons’ lipid bilayer as soliton-like electro-mechanical waves. Results and conclusion: The ideas presented in this paper provide a qualitative model for the decision-making processes in a living cell undergoing a differentiation process. Outlook: This paper paves the way for the real-time live-cell observation of information processing by microtubule-based cytoskeleton and cell fate decision making.

In general, reactive nitrogen species, like nitric oxide (NO) and peroxynitrite are classified in primary and secondary according its benefic or deleterious effects respectively. Multiple benefic roles through the body has been attributed to nitric oxide (NO), a key signaling molecule, which acts as vasodilator relaxing smooth muscles of arteries; participates in the blood pressure control; hinders the initiation of inflammation NO liberated from endothelium cells or lymphocytes to intravascular corporal fluid enter into erythrocytes through membrane band 3 protein being after captured by deoxyhemoglobin or by oxyhemoglobin. Inside the erythrocytes several chemical reactions occur with generation of S-nitrosoglutathione a NO reservoir molecules and NO derivatives (NOx) molecules namely nitrite, nitrate and peroxynitrite. The erythrocyte acts as sensor of the tissues oxygen partial pressure and consequently change its oxygen levels lead along with NO contents. NO is released through band 3 protein into the blood, at microcirculatory network, in tissues with low oxygen partial pressure. The aim of this mini review was to present the erythrocyte signal transduction pathways associated with NO and S-nitrosoglutathione efflux, metabolic behavior of the NO reservoir molecules and NO reactive species in human erythrocytes under several biological conditions. For examples, the effects of external amphipathic molecules, fibrinogen, and internal manipulation of protein phosphorylation degree and redox status on erythrocyte. NOx, NO and S-nitrosoglutathione efflux levels are herein included. Erythrocyte NO efflux evidenced as biomarkers of inflammatory vascular diseases will be herein highlighted.

A major challenge for humankind is to reduce global carbon dioxide (CO2) emissions to avoid the most harmful impacts of climate change. The transport sector is responsible for almost 1/4 of the world’s energy-related emissions, with road transportation representing around 1/5 of the fuel consumption. Electric vehicles (EVs) may help to reduce CO2 emissions, but their diffusion is uncertain due to market barriers. This paper investigates the electric vehicle (EV), which has a smaller ecological footprint, as an alternative capable of meeting the needs of personal transport in Brazil. To carry out this evaluation, the study considers socio-techno-economic and political-environmental-innovation aspects to assess the challenges and opportunities facing the adoption of electric vehicles. The analysis was carried out based on a survey administered to a wide range of stakeholders. A SWOT analysis was performed to understand the most critical factors affecting the future of EVs in Brazil, which is a top-ten automotive manufacturer worldwide and a leader in sugar cane ethanol production. The results suggest light-duty electric vehicles (LDEV) as a first option for low-carbon passengers’ mobility and that EVs expansion will require market regulation, incentive policies and adequate charging infrastructure. Both consumers and society in general will benefit most from the expansion of EVs due to low emissions and total cost of ownership (TCO). The results show where decision-makers should focus their attention.
