Abstract:
Considerando a importância da Alquimia e seu contexto histórico, a presente pesquisa teve como objetivo compreender como a Alquimia é explorada nas obras didáticas aprovadas pelo Programa Nacional do Livro Didático (PNLD) de 2018. Trata-se de uma pesquisa de natureza qualitativa. Para análise dos livros didáticos, utilizamos como critério as marcas da historiografia tradicional apontadas por Beltran, Saito e Trindade (2014), e os livros didáticos foram identificados pelas letras LD, seguidas por um código numérico: LD1, LD2, LD3, LD4, LD5, LD6. Pela análise dos livros didáticos, identificaram-se características da perspectiva historiográfica tradicional, consideradas ultrapassadas por Beltran, Saito e Trindade (2014), o que evidencia que, de modo geral, não há importante valorização da nova historiografia da ciência. Verificou-se que, em LD4, a Alquimia não é contemplada em nenhum dos capítulos, enquanto que apenas LD5 apresenta poucos aspectos da antiga historiografia, evidenciando que os autores buscaram inserir a nova historiografia da ciência em sua abordagem. De modo geral, os livros didáticos analisados fazem uma abordagem da Alquimia que carece de informações históricas e ainda é permeada por aspectos da antiga historiografia da ciência.

Abstract:
Abstract To measure activities of lactate dehydrogenase (EC 1.1.1.27) isoenzymes LD1 and LD2 in serum, we developed a method involving 1,6-hexanediol as specific inhibitor of the M-subunit. Addition of hexanediol, 0.6 mol/L, to five LD isoenzyme fractions purified from human liver and heart homogenates resulted in complete loss of activities of LD4 and LD5, and partial loss of LD2 and LD3. The activity of LD1, which is composed of the H-subunit only, was not affected. In studying what conditions would allow only the activities of LD1 or LD1 + LD2 to be expressed in serum, we found that the respective activities could be determined by treatment with hexanediol, 0.75 mol/L and 0.55 mol/L, respectively. Results of binding experiments and analytical-recovery tests supported the effectiveness of analyses with this inhibitor in determination of LD1 and LD1 + LD2 activities in serum. Results by this proposed inhibition method correlated well with those by the conventional electrophoretic method for determination of LD1 activity, but LD1 + LD2 activities by the inhibition method were a little less than those by the electrophoretic method, requiring some correction.

Abstract:
Singularity problems of scatter matrices in Linear Discriminant Analysis (LDA) are challenging and have obtained attention during the last decade. Linear Discriminant Analysis via QR decomposition (LDA/QR) and Direct Linear Discriminant analysis (DLDA) are two popular algorithms to solve the singularity problem. This paper establishes the equivalent relationship between LDA/QR and DLDA. They can be regarded as special cases of pseudo-inverse LDA. Similar to LDA/QR algorithm, DLDA can also be considered as a two-stage LDA method. Interestingly, the first stage of DLDA can act as a dimension reduction algorithm. The experiment compares LDA/QR and DLDA algorithms in terms of classification accuracy, computational complexity on several benchmark datasets and compares their first stages. The results confirm the established equivalent relationship and verify their capabilities in dimension reduction.

Abstract:
Background:Due to the complex nature of psoriatic arthritis (PsA), diverse disease activity measures have been developed, the most common of which include Disease Activity Score for Psoriatic Arthritis (DAPSA), Minimal Disease Activity (MDA) and Very Low Disease Activity (VLDA). Recently, new composite measures have been developed such as Psoriatic Arthritis Disease Activity Score (PASDAS) and GRACE index. Due to different domains and assessments, even though these measures may indicate remission or low disease activity, residual disease activity (RDA) may persist.Objectives:The aim of this study was to evaluate RDA in patients with PsA.Methods:A total of 148 patients (105 female, 43 male; mean age 47.5 (SD:12.6) years) who met the CASPAR criteria for PsA were recruited. Demographic and clinical characteristics of patients were recorded, including pain visual analog scale (VAS), joint VAS, patient global VAS, and tender and swollen joint counts. Evaluations included the Leeds Enthesitis Index (LEI), Psoriasis Area and Severity Index (PASI), Psoriatic Arthritis Quality of Life (PsAQoL), Short-Form 36 Health Survey (SF-36) and Health Assesment Questionnaire (HAQ). Disease activity and remission were assessed using the DAPSA, MDA, VLDA, PASDAS and GRACE Index. MDA was calculated with 5 and 6 positivity criteria separately. Low disease activity (LDA) was defined as follows: DAPSA≤14, PASDAS≤3.2 and GRACE Index≤2.3. RDA was defined as the presence of at least one of the following criteria despite remission or LDA: tender and/or swollen joints >1, dactilitis >1, LEI>1, HAQ>0.5, PASI>1, PtGA>20, physician VAS>20, or pain VAS>15.Results:The mean duration of disease was 68.2 (SD:80.2) months. DAPSA-LDA, PASDAS-LDA, GRACE-LDA, MDA and VLDA were observed in 48.6%, 14.6%, 14.9%, 23.6% and 2% of PsA patients, respectively. RDA as determined by at least one domain was identified in 91%, 95%, 86% and 86% of patients who were classified as having MDA, DAPSA-LDA, PASDAS-LDA and GRACE-LDA, respectively. Undetected RDA was most common with DAPSA, whereas VLDA completely ruled out RDA. PASDAS and GRACE resulted in similar rates of RDA (Table-1). With DAPSA-LDA, the incidence of RDA in the pain domain was significantly lower with older age. Female patients had higher rates of RDA with the LEI and HAQ (p<0.05).Conclusion:VLDA was the most and DAPSA was the least sensitive method to detect remission/LDA. RDA should be kept in mind in patients with PsA when using current measures to assess remission or LDA.References:[1]Ennio Lubrano, Silvia Scriffignano, Fabio Massimo Perrotta, Residual disease activity and associated factors in Psoriatic Arthritis.

Abstract:
ABSTRACT The O26 serogroup of enteropathogenic Escherichia coli (EPEC) is one of the serogroups most frequently implicated in infant diarrhea and is also common among enterohemorrhagic E. coli (EHEC) strains. The most common O26 strains belong to EPEC/EHEC serotype O26:H11 and are generally Shiga toxin (Stx) positive. Stx-negative E. coli strains that are negative for the EPEC EAF plasmid and bundle-forming pilus (Bfp) are classified as atypical EPEC. Here, we report a novel adhesin present in an stx-negative bfpA-negative atypical EPEC O26:H11 strain isolated from an infant with diarrhea. A cloned 15-kb genomic region from this strain, designated the locus for diffuse adherence (lda), confers diffuse adherence on HEp-2 cells when expressed in E. coli K-12. Sequence analysis of lda revealed a G+C content of 46.8% and 15 open reading frames sharing homology with the E. coli K88 fae and CS31A clp fimbrial operons. The lda region is part of a putative 26-kb genomic island inserted into the proP gene of the E. coli chromosome. Hybridization studies have demonstrated the prevalence of the minor structural subunit gene, ldaH, across E. coli serogroups O5, O26, O111, and O145. A second plasmid-encoded factor that contributed to the Hep-2 adherence of this strain was also identified but was not characterized. Null mutations that abolish adherence to HEp-2 cells can be restored by plasmid complementation. Antiserum raised against the major structural subunit, LdaG, recognizes a 25-kDa protein from crude heat-extracted protein preparations and inhibits the adherence of the E. coli DH5α lda + clone to HEp-2 cells. Electron microscopy revealed a nonfimbrial structure surrounding the bacterial cell.

Abstract:
Linear discriminant analysis (LDA) is one of the important techniques for dimensionality reduction, machine learning, and pattern recognition. However, in many applications, applying the classical LDA often faces the following problems: (1) sensitivity to outliers, (2) absence of local geometric information, and (3) small sample size or matrix singularity that can result in weak robustness and efficiency. Although several researchers have attempted to address one or more of the problems, little work has been done to address all of them together to produce a more effective and efficient LDA algorithm. This article proposes 3E-LDA, an enhanced LDA algorithm, that deals with all three problems as an attempt to further improve LDA. It proposes to learn a weighted median rather than the mean of the samples to deal with (1), to embed both between-class and within-class local geometric information to deal with (2), and to calculate the projection vectors in the null space of the matrix to deal with (3). Experiments on six benchmark datasets show that these three enhancements enable 3E-LDA to markedly outperform state-of-the-art LDA baselines in both accuracy and efficiency.

Abstract:
This article describes how text documents are a major data structure in the era of big data. With the explosive growth of data, the number of documents with multi-labels has increased dramatically. The popular multi-label classification technology, which is usually employed to handle multinomial text documents, is sensitive to the noise terms of text documents. Therefore, there still exists a huge room for multi-label classification of text documents. This article introduces a supervised topic model, named labeled LDA with function terms (LF-LDA), to filter out the noisy function terms from text documents, which can help to improve the performance of multi-label classification of text documents. The article also shows the derivation of the Gibbs Sampling formulas in detail, which can be generalized to other similar topic models. Based on the textual data set RCV1-v2, the article compared the proposed model with other two state-of-the-art multi-label classifiers, Tuned SVM and labeled LDA, on both Macro-F1 and Micro-F1 metrics. The result shows that LF-LDA outperforms them and has the lowest variance, which indicates the robustness of the LF-LDA classifier.

Abstract:
Most of the existing recommender systems are based only on the rating data, and they ignore other sources of information that might increase the quality of recommendations, such as textual reviews, or user and item characteristics. Moreover, the majority of those systems are applicable only on small datasets (with thousands of observations) and are unable to handle large datasets (with millions of observations). We propose a recommender algorithm that combines a rating modeling technique (i.e., Latent Factor Model) with a topic modeling method based on textual reviews (i.e., Latent Dirichlet Allocation), and we extend the algorithm such that it allows adding extra user- and item-specific information to the system. We evaluate the performance of the algorithm using Amazon.com datasets with different sizes, corresponding to 23 product categories. After comparing the built model to four other models, we found that combining textual reviews with ratings leads to better recommendations. Moreover, we found that adding extra user and item features to the model increases its prediction accuracy, which is especially true for medium and large datasets.

Abstract:
Latent Dirichlet Allocation(LDA) is an efficient method of text mining,but applying LDA directly to Chinese micro-blog texts will not work well because micro-blogs are more social, brief, and closely related with each other. Based on LDA, this paper proposes a Micro-blog Relation LDA model (MR-LDA), which takes the relations between Chinese micro-blog documents and other Chinese micro-blog documents into consideration to help topic mining in micro-blog. The authors extend LDA in the following two points. First, they aggregate several Chinese micro-blogs as a single micro-blog document to solve the problem of short texts. Second, they model the generation process of Chinese micro-blogs more accurately by taking relationship between micro-blog documents into consideration. MR-LDA is more suitable to model Chinese micro-blog data. Gibbs sampling method is borrowed to inference the model. Experimental results on actual datasets show that MR-LDA model can offer an effective solution to text mining for Chinese micro-blog.

Abstract:
Num mercado de trabalho cada vez mais exigente, não só a experiência profissional é valorizada como também a capacidade de polivalência em diversas áreas. Para além da procura valorizar cada vez mais o currículo dos candidatos, existe uma necessidade crescente de contratar profissionais que consigam fazer o maior número de tarefas possível, pois, ter um conhecimento vasto permite, também, saber o que exigir de cada área, de modo a conseguir um resultado final com mais qualidade e menos dispendioso. Por isso, este relatório não trata apenas de montagem de cinema, mas sim de quase todas as áreas da pós-produção cinematográfica, como a sonoplastia e a correção de cor. Serão também abordadas as várias diferenças da realização dos processos referidos a nível profissional e académico. Deste modo, o objectivo deste relatório consiste em dar a conhecer estas duas vertentes e os conhecimentos que adquiri durante o estágio.
In a labor market increasingly demanding, not only work experience is valued as well as the ability to multi-skilling in various areas. Apart from the search of curriculums with a higher professional experience, there is an increasing need to hire professionals who can do more than one task, because having a vast knowledge also allows us to know what to demand in each area, so to achieve an end result of better quality and less expensive. Therefore, this report is not just about film editing, but almost all areas of post-production film, such as sound effects and color correction. I will also address the various differences to the completion of the procedures referred both in their professional and academic state. Thus, the purpose of this report is to make known these two aspects and the knowledge I gained during the internship.

Abstract:
Não basta ter uma câmara de filmar para um indivíduo se autodenominar produtor ou até mesmo realizador. É indispensável adquirir conhecimentos teóricos, técnicos e práticos, que se aprofundam sobretudo no confronto com uma primeira experiência profissional. Não só tive a oportunidade de testar algumas das competências adquiridas durante a parte curricular do mestrado, como também pude observar, a partir de um ponto de vista privilegiado, a realidade estrutural da produção audiovisual em Cabo Verde. O cinema encontra–se numa fase de implementação em Cabo Verde. Já existem algumas empresas no ramo de Audiovisual tal como a Viva Imagens. Existe também a Direção Nacional das Artes que com o núcleo Cinemídia se encontra a desenvolver projetos nas áreas do Audiovisual e do Cinema. Sendo o audiovisual uma área recente em Cabo Verde, existem poucos profissionais da área. Assim sendo, é desvalorizado o trabalho dos profissionais. Deparei que a maioria dos “profissionais da área” não tem formação adequada nem a possibilidade de tê-la, recorrendo assim a instituições governamentais, nomeadamente à Direção Nacional das Artes (Ministério da Cultura), para obter algum tipo de formação adequada nos ramos do audiovisual e do cinema. É importante defender e sustentar a Ideia de se criarem mecanismos para que tanto instituições públicas ou privadas valorizem o audiovisual e o cinema, através de ações de formação, workshops, tertúlias, no sentido de se formar profissionais qualificados que possam, por sua vez, passar a sua aprendizagem às gerações futuras. O mercado privado opta por mão de obra pouco qualificada pois financeiramente é mais rentável, o que limita a qualidade. Estas lacunas são facilmente identificadas quando se analisam os trabalhos realizados. A carência de meios e a fraca exigência por parte dos clientes fazem com que a realidade seja muito diferente de Portugal. Não existindo uma instituição que regule os preços, os orçamentos variam de acordo com a vontade das empresas, o que torna o mercado desleal, dando a oportunidade ao cliente de requisitar vários orçamentos, onde as diferenças de preço podem ser gigantescas (sem haver necessariamente um retorno de qualidade técnica ou estética que o justifique). Os valores que são pagos pelo produto não justificam, muitas vezes, que exista um grande investimento na produção e numa equipa qualificada. Muitos dos profissionais adquirem experiência somente através da pratica. As ideias existem, mas quando não são executadas as tarefas de planeamento características da pré-produção, acaba por prevalecer o improviso nas rodagens, o que vem dificultar também a pós-produção e a coerência final dos produtos ou objetos audiovisuais e cinematográficos. Esta é uma das conclusões essenciais a que cheguei através da realização do estagio. Lamentavelmente, quem solicita este tipo de trabalho nem sempre tem uma ideia do trabalho e do tempo que estão por “detrás” da produção de um produto audiovisual. Quando um cliente encomenda um trabalho encontra-se já muito próximo da red line, não facilitando o trabalho à empresa e à equipa. Sem espaço de tempo para desenvolver e estruturar o projeto, o resultado é sempre insatisfatório para o profissional e para o cliente, o que faz com que muitas vezes os trabalhos tenham de ser feitos de raiz. Ao apresentar a minha candidatura de estágio, propus que fosse nas áreas de produção e pós-produção (tratamento de imagem), no sentido de serem as áreas de interesse pessoal e profissional principais. Devido à realidade presenciada tive que me envolver na fase de pré produção. Senti alguma dificuldade em adaptar-me à metodologia corrente na empresa, sendo que todos se formaram nos Estados Unidos, havendo portanto um método de trabalho diferente daquele a que estava habituado e para o qual tinha sido preparado. Baseado nos conhecimentos adquiridos durante o mestrado e apoiado em bibliografia específica, fui aplicando essa metodologia de trabalho às diferentes fases de produção. Na pré produção procurei implementar, de forma mais sistemática, a preparação de todo o projeto, nomeadamente a escrita do guião, a planificação e os levantamentos para que a rodagem e a pós produção decorressem com menos sobressaltos e de acordo com o que estava inicialmente planeado e previsto. Com base nas ideias apresentadas em cada projeto fui desenvolvendo os guiões técnicos, os storyboards e os levantamentos. Devido ao grupo de trabalho ser pequeno tinha-mos que multiplicar os esforços pois só assim seria possível eu acompanhar e desempenhar várias tarefas. Perde-se algum tempo a realizar essas tarefas, mas no final o resultado é satisfatório para todos. Os conhecimentos adquiridos na disciplina de Realização Cinematográfica auxiliaram muito para que fosse possível implementar um trabalho global de planificação, para o desenvolvimento menos improvisado dos projetos. Assim sendo, através do meu conhecimento consegui implementar uma nova atitude, conjuntamente com os colegas, uma metodologia estruturada por fases, aplicada nos projetos realizados durante o período de estagio, nomeadamente: Pré-Produção - escrita do guião, planificação, levantamentos e planeamento da produção. Produção- rodagem, captação de imagem e som Pós-produção- análise dos conteúdos, montagem, tratamento de imagem e som, correção de cor, genéricos inicial e de intervalo. Estas fases são pouco respeitadas, principalmente quando se trata da fase de pré-produção e pós-produção, baseando-me para o afirmar numa análise feita de alguns produtos audiovisuais elaborados em Cabo Verde (assim como a partir da dinâmica de funcionamento da própria empresa). Este relatório também se debruça sobre os contactos estabelecidos com os responsáveis do audiovisual e do cinema “Cinemídia”.
It is not just having a camera to film for a person to call themselves producers or even directors; the idea is to acquire technical and practical knowledge. It is essential to acquire theoretical knowledge, technical and practical, which deepens especially in comparison with a first professional experience. It was an opportunity to test some of the skills acquired during the master's degree curricular as well as it was observed, from a privileged point of view, the structural reality of audiovisual production in Cape Verde. Cinema is in the implementation phase in Cape Verde, there are already some companies in the field of Audiovisual such as Viva Images. The National Directorate of Arts with core in the Cinemídia department is developing projects in the area of Audiovisual and Cinema. Being the latest in audiovisual an area Cape Verde, there are few professionals so the work is being devalued of professionals. Most "professionals" do not have adequate training or the possibility of having it, thus using government institutions, including the National Arts (Ministry of Culture), to get some sort of proper training in the fields of audiovisual and cinema. It is important to defend and support the idea of creating mechanisms for both public and private institutions value the audiovisual and cinema, through training activities, workshops, gatherings, to graduating qualified professionals who can, in turn pass their learning to future generations. It is noted that most "professionals" do not have adequate training or the possibility of having it, thus using government institutions including the National Arts (Ministry of Culture), to get some kind of formal training relating to audiovisual and cinema. It is important to defend and support the idea of creating mechanisms for both public and private institutions value the audiovisual and cinema, through training activities, workshops, gatherings, to graduating qualified professionals who can, in turn, pass their learning to future generations. The private market opts for unskilled labor as is financially more profitable, which limits the quality. These gaps are easily identified when analyzing the work done. The private market opts for unskilled labor as is financially more profitable, which limits the quality. The lack of resources and weak demand from customers make the reality very different from Portugal. In the absence of an institution that regulates prices, budgets vary according to the willingness of enterprises, which makes for unfair market, giving the opportunity to the client to request multiple budgets, where the price difference can be huge (without having a technical quality or esthetics or to justify it). The amounts that are paid for the product, do not justify that there is a large investment in producing a qualified team. Many professionals acquire experience through practice. Ideas emerge, but when it runs the actions of pre-production, ultimately leads to improvise in filming makes it difficult for post-production. This is one of the insights that I could get through the training. Unfortunately, those caring for this kind of work do not always have an idea of the design of audiovisual product, when it is already considerately near the red line. No time to develop and structure the project, the result is always unsatisfactory for the professional and the client, and they are often remade from the beginning. At present my candidacy for training, I proposed the areas of production and post-production "Image Treatment" in the sense of being the areas of personal and professional interest. Because the reality witnessed had to engage in preproduction. With some difficulty adapting my current methodology in the company, all of which created in the United States, the working method employed is different. Based on the ideas presented in each project was developing the scripts technicians, storyboards and surveys. The ideas presented in the project was developing the scripts and technical storyboard, thus initiating the project. Because the working group are considerably low, we had to multiply the efforts because only then could I follow and perform various tasks. You lose yourself some time to perform these actions, but in the end, the result is satisfactory for all. The knowledge gained in the discipline of Film Directing helped much so that it was possible to implement actions to develop the projects. Thus, through my knowledge I could implement a new attitude along with other colleagues, a structured methodology for phases, namely. Pre-Production-writing the script, planning, surveying and production planning. Production shooting, capturing images and sound Post-production of content analysis, assembly, image processing and sound, color correction, and generic initial interval. Applied in projects developed during the internship. These phases are rarely practiced especially when it comes to the preproduction and post-production, based on analysis made by audiovisual products produced in Cape Verde. This report is also a description of self-acknowledgement, in search of those responsible for the audiovisual and cinema "Cinemídia".

O presente projecto tem como finalidade descrever todas as vertentes da elaboração do Plano de Negócios da empresa Arremedilho de Sabores - Restauração, Lda, nomeadamente a sua contextualização teórica, legal, económica e financeira. Ao pretender conciliar o degustar de uma refeição com a necessidade que o consumidor actual sente em experimentar novas sensações (especialmente experiências com conteúdo cultural e/ou histórico), torna-se, assim, apelativo a um consumidor de classe média/alta e alta, nacional e internacional, principalmente urbano, muito informado, exigente e com acesso a vários canais de comunicação (factor chave de fidelização de clientes com o objectivo de estes serem os principais promotores de todo o conceito). Arremedilho de Sabores - Restauração, Lda posiciona-se no mercado da restauração (maduro e fragmentado) através da diferenciação (serviço/produto). Com um investimento inicial de 140 000€, apresenta-se como um projecto viável uma vez que o VAL apresenta um valor positivo, no quinto ano, de 25.547,45€ mostrando bons níveis de rentabilidade, autonomia financeira e liquidez; ### ABSTRACT: This project aims to describe a business plan for the company “Arremedilho de Sabores - Restauração, Lda.”. It will focus essentially in the theoretical, legal, economic and financial issues that need to be analyzed. In order to differentiate itself, the company intends to provide a high quality service where the meal’s good taste will be combined with cultural and historical themes. The main target becomes the middle/high class consumer, usually well informed and used to the urban lifestyle (national individuals and international ones). The high quality of the service provided together with the spread of its reputation will also work in a way that consumers will feel the need of returning. With a very mature and fragmented market, the company will position itself in such way that the competitive advantage will be assured by a differentiation strategy. The initial investment will be of 140.000,00€, which makes this a viable and doable project. Is expect a NPV of 25.547,45 € in the fifth year, which from a financial point of view is in accordance with a good level of autonomy and liquidity.

Abstract:
Projeto profissionalizante do mestrado em Gestão, apresentado à Faculdade de Economia da Universidade de Coimbra, sob a orientação de Filipe Coelho e Carlos Alberto de Oliveira Catrocho.
O projecto profissionalizante começa com um pequeno prefácio onde evidencio as mais-valias e a motivação que o projecto me trouxe durante a sua execução. Seguidamente passo para a análise teórica, começando por uma breve introdução da situação actual global e salientando a necessidade de as empresas se adaptarem à mudança. A definição de marketing, formulação da estratégia, a importância do marketing na formulação e implementação da estratégia e os benefícios e objecções ao plano de marketing são os pontos fulcrais da análise teórica. De seguida descrevo a história da empresa desde a data de fundação até aos dias de hoje salientando algumas das campanhas e estratégias mais relevantes para o sucesso da empresa. O ponto seguinte é a análise externa, com a análise PEST complementando-a com um quadro síntese onde se destaca os efeitos positivos e negativos assim como as tendências. Após a análise PEST segue-se a análise do meio envolvente transaccional começando pela análise do sector, dos consumidores, dos concorrentes a nível nacional e especificando três dos concorrentes que achei mais relevantes para a comparação com a Góis, concluindo com a análise das 5 forças de Porter. Seguidamente vem a análise da empresa destacando os seus produtos, preços, distribuição, comunicação, estratégia de expansão, a imagem da empresa e os seus fornecedores. Após esta análise foi criada a Competitive Profile Matrix onde se compara duas das três concorrentes analisada com a Góis. A análise SWOT conclui o diagnóstico. O ponto seguinte do plano de Marketing é o estabelecer de objectivos para dar começo à estratégia de Marketing. Na estratégia de Marketing é efectuada a análise à segmentação e público-alvo, ao posicionamento pretendido para a Góis, assim como ao Marketing-mix englobando os produtos, preço, distribuição e comunicação. Plano de Marketing Faculdade de Economia da Universidade de Coimbra (2010/2011) 4 A elaboração de um plano de acção é o ponto que se segue destacando preferencialmente as acções de comunicação e a entrada de novos produtos. Para todas estas acções é efectuado uma planificação mensal de execução, seguido de uma avaliação da estratégia e os respectivos planos de contingência. Para finalizar vem a conclusão, destacando o posicionamento da empresa, a formação de funcionários, atendimento personalizado, produtos exclusivos e os seus espaços inovadores. De acrescentar que alguma das estratégias definidas para o ano de 2011 já foram aplicadas com sucesso. O projecto acaba com a bibliografia e os anexos com imagens das marcas da Góis e os seus pontos de venda.

Full text
Abstract:
This paper investigates the feasibility of using non-cerebral, time-series data to detect epileptic seizures. Data were recorded from fifteen patients (7 male, 5 female, 3 not noted, mean age 36.17 yrs), five of whom had a total of seven seizures. Patients were monitored in an inpatient setting using standard video electroencephalography (vEEG), while also wearing sensors monitoring electrocardiography, electrodermal activity, electromyography, accelerometry, and audio signals (vocalizations). A systematic and detailed study was conducted to identify the sensors and the features derived from the non-cerebral sensors that contribute most significantly to separability of data acquired during seizures from non-seizure data. Post-processing of the data using linear discriminant analysis (LDA) shows that seizure data are strongly separable from non-seizure data based on features derived from the signals recorded. The mean area under the receiver operator characteristic (ROC) curve for each individual patient that experienced a seizure during data collection, calculated using LDA, was 0.9682. The features that contribute most significantly to seizure detection differ for each patient. The results show that a multimodal approach to seizure detection using the specified sensor suite is promising in detecting seizures with both sensitivity and specificity. Moreover, the study provides a means to quantify the contribution of each sensor and feature to separability. Development of a non-electroencephalography (EEG) based seizure detection device would give doctors a more accurate seizure count outside of the clinical setting, improving treatment and the quality of life of epilepsy patients.

Full text
Abstract:
This paper investigates the relationship between the views expressed in the minutes of the meetings of the Central Bank of Brazil’s Monetary Policy Committee (COPOM) and the real economy. It applies various computational linguistic machine learning algorithms to construct measures of the minutes of the COPOM. First, we create measures of the content of the paragraphs of the minutes using Latent Dirichlet Allocation (LDA). Second, we build an uncertainty index for the minutes using Word Embedding and K-Means. Then, we combine these indices to create two topic-uncertainty indices. The first one is constructed from paragraphs with a higher probability of topics related to “general economic conditions”. The second topic-uncertainty index is constructed from paragraphs that have a higher probability of topics related to “inflation” and the “monetary policy discussion”. Finally, we employ a structural VAR model to explore the lasting effects of these uncertainty indices on certain Brazilian macroeconomic variables. Our results show that greater uncertainty leads to a decline in inflation, the exchange rate, industrial production and retail trade in the period from January 2000 to July 2019.
