Este artigo apresenta uma investigação acerca dos métodos de análise e argumentação presentes no trabalho do crítico de cinema Ely Azeredo sobre o Cinema Marginal. O objetivo deste estudo foi encontrar respostas para o posicionamento negativo do crítico a este movimento que marcou a modernização da cinematografia brasileira. Para esta análise, foram selecionados dois textos publicados no periódico carioca Jornal do Brasil a respeito das obras O Bandido da Luz Vermelha (1968) e A Mulher de Todos (1969), de Rogério Sganzerla. Os textos apresentam opiniões divergentes de Ely Azeredo sobre a obra em questão, contrastando com o julgamento hegemônico de sua época, que articulava-se de maneira a exaltar as inovações narrativas, técnicas e temáticas que tais obras continham.
This thesis aimed to demonstrate the forestry potential of pellets and / or electricity production in the district of Bragança. First, the use of Forest Biomass at international and national level was analyzed to better situate the forestry market and its growing potential up to today. Then, the forest operating systems existing able to be used were analyzed, dividing them into five components: activities of production, forest biomass transportation, forest processing systems, and conversion technologies. Next, a review of forest biomass in the district of Bragança, using the 2007 Land Cover Map for Continental Portugal, the 5th National Forest Inventory and Florestat 5.0 software, was carried. For annual values of forest biomass to be industrially processed, three scenarios were considered (conservative, regular and optimistic) estimating 144.645, 227.484 and 340.340 tones to be of industrial processes, using as example of study the pellet production plant and thermoelectric power station of Mortágua, Viseu. The values of annual production of pellets range from 57.607 to 135.545 tonnes re-sulting in sales between 1,8 to 4,3 M€, and, for the thermoelectric power station the production was between 134,3 to 316 GWh achieving sales between 2,4 to 5,7 M€. An estimate of electricity dependence reduction was performed to the district of Bragança using forest biomass, reaching 58% for a conservative scenario and 137% for an optimist scenario. Finally, the political and environmental limitations are presented per scenario. Esta tese teve como objetivo demonstrar o potencial florestal na produção de pellets e / ou eletricidade no distrito de Bragança. Inicialmente descreveu-se o uso da Biomassa Florestal a nível internacional e nacio-nal, para melhor situar o mercado florestal e o seu crescente potencial até aos dias de hoje. Seguidamente foram analisados os sistemas operativos florestais, dividindo-os em cinco componentes: atividades de produção, transporte da biomassa florestal, sistemas de processamento florestal, transformação da biomassa florestal em produto final e tec-nologias de conversão. Com uso da Carta de Ocupação do Solo de 2007, do 5.º Inventário Florestal Nacio-nal e software Florestat 5.0 foi determinada a área florestal de potencial interesse no distrito de Bragança. Consideraram-se três cenários de acréscimos médios anuais (con-servador, regular e otimista) estimando valores de 144.645, 227.484 e 340.340 tonela-das secas de biomassa florestal para serem industrialmente processadas, usando como exemplo de estudo a fábrica de produção de pellets e a central termoelétrica em Mortá-gua, Viseu. Estimaram-se valores de produção anual de pellets entre 57.607 a 135.545 toneladas originando vendas de 1,8 a 4,3 milhões de Euros, e, a produção termoelétrica variou entre 134,3 a 316 GWh, atingindo vendas entre 2,4 a 5,7 milhões de Euros. Ainda se estimou a redução da dependência elétrica no distrito de Bragança com uso da biomassa florestal, atingindo 58% para um cenário pessimista e 137% para um cená-rio otimista. Finalizando, são apresentadas as limitações, conclusões e trabalho futuramente a desenvolver.
The Natural Language Processing (NLP) community has witnessed huge improvements in the last years. However, most achievements are evaluated on benchmarked curated corpora, with little attention devoted to user-generated content and less-resourced languages. Despite the fact that recent approaches target the development of multi-lingual tools and models, they still underperform in languages such as Portuguese, for which linguistic resources do not abound. This paper exposes a set of challenges encountered when dealing with a real-world complex NLP problem, based on user-generated complaint data in Portuguese. This case study meets the needs of a country-wide governmental institution responsible for food safety and economic surveillance, and its responsibilities in handling a high number of citizen complaints. Beyond looking at the problem from an exclusively academic point of view, we adopt application-level concerns when analyzing the progress obtained through different techniques, including the need to obtain explainable decision support. We discuss modeling choices and provide useful insights for researchers working on similar problems or data.
Life Cycles of both products and services significantly consume renewable and non-renewable resources across a worldwide scale. Thus, eliciting an enormous environmental impact, that is known to disproportionately instigate crises into the socio-economic and political domains of our civilization. Therefore, Creation of Shared Value and Corporate Social Responsibility (CSR) have been considered by Policy makers, Public and Private Institutions. In addition to Corporate Philanthropy, CSR practices also encompass a wide spectrum of activities, including Stakeholder safety/welfare, designing sustainable products and ecological restoration to name a few which are ascertained to capital and knowledge intensive in nature. Therefore, this paper primarily structures the scope of CSR and proposes a mechanism for trading Corporate Social Responsibility credits in order to incentivize stakeholder centered business practices. Furthermore, the CSR credits trading methodology would entail similar mechanisms used by its remotely successful predecessors namely, tax incentives, tradable credits/certificates and flexible mechanisms for implementing sustainable projects. The CSR credits trading methodology is envisioned to entail a more holistic approach towards overall Sustainability when compared to Carbon Offsets/Renewable Energy Certificates which are more focused towards reducing the environmental footprint. ; The author acknowledges the contribution of MIT Portugal Program, University of Minho and Fundação para a Ciência e Tecnologia (FCT), Portugal (Foundation Of Science and Technology, Portugal) for the scholarship grant SFRH / BD / 33794 / ...
IntroductionConsistent use of PrEP reduces HIV transmission from sexual practices amongst men who have sex with men (MSM) up to 92% [1]. Lisbon MSM cohort study estimates point that 59.3% of their participants at entrance (1593 HIV negative MSM enrolled between April 2011 and May 2013) were eligible for PrEP [2], according to the 2014 USA PrEP guidelines [3]. Studies about PrEP acceptability and implementation support policies aimed at increasing and rolling out its use. Hence, the exploratory study about PrEP acceptability in MSM at Lisbon.Materials and MethodsA street‐based intercept survey, adapted from Mantell et al. study [4], was the one used on MSM attending the 2014 Lisbon pride fair. The survey included socio‐demographic data, PrEP awareness and readiness to use it, probability of MSM's social network to also use it, promptness to join PrEP‐related studies, type of PrEP warranted and condomless anal sex practice in the last six months.ResultsA total of 110 HIV negative Portuguese MSM responded, with a median age of 33% and 84% of them identified themselves as gay. A majority of MSM were unaware of PrEP (59%); those that were aware, had heard of it trough CheckpointLx (31%), internet (22%) or health professionals (20%). 66% were likely or very likely to participate in PrEP‐related studies. 57% of MSM were likely or very likely to use PrEP if available and reported that some, if not almost all of their social network, will do it too (70%). Type of PrEP preferred was oral, a pill a day (43%), followed by oral, intermittent intake (32%). Overall 41% of MSM had condomless anal sex practice in the last six months.ConclusionsIn this MSM Portuguese sample, a general willingness to adopt PrEP was predominant, specially the oral daily intake. Forty‐one percent of participants had had condomless anal sex practice in the last six months and therefore fitted within the criteria to be on Pre‐Exposure Prophylaxis (PrEP), according to MSM Risk Index in 2014 USA PrEP guidelines. PrEP, when available in Portugal, should be a powerful tool for HIV prevention in this key population.
Industrial manufacturing is moving towards flexible and intelligent processes. Human-Robot Collaboration (HRC) has a pivotal role in smart factories due to a more versatile resource allocation that ultimately drives higher productivity and efficiency. The physical barriers that separate robots' and humans' workspaces are removed to facilitate HRC, which raises new safety concerns. To cope with this new robotics paradigm, regulatory legislation and international safety standards have been issued and are enforced for any machinery placed in factories. In this paper, we aim to shorten the gap between research projects and industry-ready robotic systems, by providing the guidelines and general requirements for collaborative robotic applications. We review the current international safety standards, certification procedures under the scope of European jurisdiction, and elaborate a literature review of papers related to safety for collaborative workstations. ; This work was supported by NORTE-06-3559-FSE-000018, integrated into the invitation NORTE-59-2018-41, aiming to hire highly-qualified human resources, co-financed by the Regional Operational Programme of the North 2020, thematic area of Competitiveness and Employment, through the European Social Fund ...
