The most Portuguese village in Portugal: tradition in the age of its technical reproducibility

Ethnographic film is often associated with many European countries’ past as colonial powers and the way these countries used film to depict African, American and Asian territories and populations they once ruled. However, ethnographic film also has a European tradition of its own, closely interlaced with the history of ethnography and anthropology as autonomous sciences and with the desire of scholars to represent local, regional and national cultural identities. This paper presents a Portuguese attempt of this sort dating from 1938, when the authoritarian regime organized a national contest to determine which would be Portugal’s most “authentic” village – something other European countries also did. As part of this metonymic contribution to the construction of Portugal’s national identity as an agrarian utopia, a short documentary was shot, sponsored by the same official propaganda office that had organized the contest. In this film, the viewer’s gaze is made to coincide with the one of the national jury visiting the final selection of 12 villages and to whose benefit local scholars had organized all sorts of colourful peasant traditions hoping to cause the strongest impression. The film makes a strong case for the importance of ethnographic film as a relevant instance not only of the iteration of existing European national cultures, but also of the construction of so many of Europe’s national identities and traditions. Suffice to say that even today the village of “Monsanto”, which won the 1938 contest, is still referred to as “Portugal’s most Portuguese village”.

Multilayer Perceptron Neural Networks Training Through Charged System Search and its Application for Non-Technical Losses Detection

The non-technical loss is not a problem with trivial solution or regional character and its minimization represents the guarantee of investments in product quality and maintenance of power systems, introduced by a competitive environment after the period of privatization in the national scene. In this paper, we show how to improve the training phase of a neural network-based classifier using a recently proposed meta-heuristic technique called Charged System Search, which is based on the interactions between electrically charged particles. The experiments were carried out in the context of non-technical loss in power distribution systems in a dataset obtained from a Brazilian electrical power company, and have demonstrated the robustness of the proposed technique against with several others natureinspired optimization techniques for training neural networks. Thus, it is possible to improve some applications on Smart Grids.

Using Baseline Methods to Identify Non-technical Losses in the Context of Smart Grids

Demand response has gained increasing importance in the context of competitive electricity markets and smart grid environments. In addition to the importance that has been given to the development of business models for integrating demand response, several methods have been developed to evaluate the consumers’ performance after the participation in a demand response event. The present paper uses those performance evaluation methods, namely customer baseline load calculation methods, to determine the expected consumption in each period of the consumer historic data. In the cases in which there is a certain difference between the actual consumption and the estimated consumption, the consumer is identified as a potential cause of non-technical losses. A case study demonstrates the application of the proposed method to real consumption data.

Status of Non-Technical Losses of Electricity in Brazil

The electricity demand in Brazil has been growing. Some studies estimate that through 2035 the energy consumption (the power consumption) should increase 78%. Two distinct actions are necessary to meet this growth: the construction of new generating plants and to reduce electrical losses in the country. As the construction of power plants have a high price, coupled with the growth of (current) environmental concern, electric utilities are investing in reducing losses, both technical and non-technical. In this context, this paper aims to present an overview of nontechnical losses in Brazil and to raise a discussion on the reasons that contribute to energy fraud.

Study of Proposed Identification of Non-Technical Losses of Electricity in Brazil

The electric utilities have large revenue losses annually due to commercial losses, which are caused mainly by fraud on the part of consumers and faulty meters. Automatic detection of such losses where there is a complex problem, given the large number of consumers and the high cost of each inspection, not to mention the wear of the relationship between company and consumer. Given the above, this paper aims to briefly present some methodologies applied by utilities to identify consumer frauds.

Orbital tuberculosis diagnosed by immunohistochemistry: case reports

PURPOSE: To describe three cases of orbital tuberculosis, with their clinical characteristics and respective diagnostic procedures, showing the importance of histopathology for the correct diagnosis. PATIENTS AND METHODS: Three patients diagnosed and treated for orbital tuberculosis, in the "Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo" during the years of 1999 and 2001. RESULTS: All of the patients were female and referred a chronic evolution of swelling of one eyelid associated or not with other symptoms. They had not HIV infection. Two of them had positive epidemiology for tuberculosis. However, the search for systemic evidence of the disease and staining for bacilli (Ziehl-Neelsen method) were negative in all three patients. In all the cases, only the biopsy with immunohistochemical analysis could confirm the diagnosis. COMMENTS: Orbital involvement is a rare ocular manifestation of tuberculosis. Even in a tertiary hospital, few cases, if any, are diagnosed per year. However, the global incidence and prevalence of M. tuberculosis infections is not under control yet, and it has been a serious public health problem. Thus, one must be aware of the possibility of tuberculosis among the orbital diseases.

Inspeção a sistemas de climatização e conceção de um sistema de gestão da manutenção aplicado em edifícios universitários

Os requisitos legais impostos ao processo de manutenção das instalações de AVAC em edifícios evoluíram nos últimos 10 anos no sentido de uma crescente exigência, obrigando à existência de planos de manutenção preventiva, livros de ocorrências, inspeções obrigatórias a equipamentos, auditorias ou certi cações energéticas. Para os responsáveis da gestão da manutenção de edifícios, em particular para os que gerem uma quantidade signi cativa de equipamentos e instalações, fazê-lo sem o auxílio de uma ferramenta informática é um desa o considerável. Este trabalho visou a arquitetura de um sistema de gestão da manutenção de edifícios que foi aplicado a um caso real, nomeadamente o campus de Azurém da Universidade do Minho. Foi desenvolvida uma metodologia de inspeção, recolha e tratamento da informação para os sistemas técnicos de AVAC existentes nos edifícios. Esta metodologia foi implementada numa aplicação informática que permite aos técnicos responsáveis pela manutenção uma agilização de tarefas, resultado de um vasto conjunto de informações e de ferramentas desenvolvidas propositadamente, facilmente acessíveis através da rede Wi-Fi universitária. A integração das tarefas de manutenção na aplicação informática permitirá aumentar o grau de e ciência e e cácia nas atividades inerentes à manutenção, aumentando o grau de satisfação dos técnicos envolvidos no processo e dos utentes dos edifícios. O registo das tarefas de manutenção realizadas e dos respetivos custos em bases de dados, tornará também possível a geração de relatórios que sustentarão decisões mais assertivas. A implementação na aplicação informática dos seis módulos estruturais do Sistema de Gestão da Manutenção e Consumos Energéticos, SGMCE, permitirá atingir um nível de gestão da manutenção mais elevado, criando condições para o efetuar o comissionamento. O comissionamento prolonga-se por toda a vida do edifício, permitindo atingir os objetivos designados pelo seu promotor, dentro de patamares de custos de exploração energéticos e de custos optimizados de manutenção.

Early diagnosis of relapse in borderline leprosy: two case reports

Two cases of relapse in borderline leprosy were reported. Despite the late-reversal, reaction-like feature, the suspicion of relapse in both was based on persistent and slow-developing skin lesions and an absence of acute neuritis or reaction during one year of follow-up. The authors have considered this possible occurrence in lepromatous borderline-treated patients after their immune cellular restoration and defend that not all Type 1 reactions would be an inflammatory answer to persistent Mycobacterium leprae, but that they could be. Therefore, a relapse diagnosis could be applied and it is more advisable, as one year of Multi-Drug Therapy (MDT) is less dangerous and more efficient for these cases than one year of corticosteroids.

Calciphylaxis: a Literature Review Based in Two Case Reports

Calciphylaxis is a rare and devastating obliterative vasculopathy, leading to ischemia and subcutaneous necrosis. In most cases it affects patients with renal disease and is associated with high morbidity and mortality. We present two case reports followed recently in our department, and a literature review on this topic. Case one refers to an 80 -year -old Caucasian woman with chronic kidney disease stage 5 and primary hyperparathyroidism with secondary brown tumour and calciphylaxis. Case two refers to a 59 -year -old Caucasian woman admitted with severe nephrotic syndrome associated with amyloidosis, that developed a catastrophic picture of calciphylaxis, ending in the patient’s death. There is a critical need to understand the pathogenesis of calciphylaxis. Its comprehension is the only way to improve the survival of these patients, and may help to elucidate the pathophysiology of vascular calcification in general. Educating physicians in the prevention and early detection of calciphylaxis is crucial. Only by increasing the knowledge about risk factors, pathophysiology, response to treatment and outcome, will we be able to improve prophylaxis and therapy of patients with calciphylaxis, decreasing the high mortality of this entity.

Innovation and environmental policy: Clean vs. dirty technical change

We study a two sector endogenous growth model with environmental quality with two goods and two factors of production, one clean and one dirty. Technological change creates clean or dirty innovations. We compare the laissez-faire equilibrium and the social optimum and study first- and second-best policies. Optimal policy encourages research toward clean technologies. In a second-best world, we claim that a portfolio that includes a tax on the polluting good combined with optimal innovation subsidy policies is less costly than increasing the price of the polluting good alone. Moreover, a discriminating innovation subsidy policy is preferable to a non-discriminating one.

Graph usage in financial reports: Evidence from Portuguese listed companies

When assessing investment options, investors focus on the graphs of annual reports, despite lack of auditing. If poorly constructed, graphs distort perceptions and lead to inaccurate decisions. This study examines graph usage in all the companies listed on Euronext Lisbon in 2013. The findings suggest that graphs are common in the annual reports of Portuguese companies and that, while there is no evidence of Selectivity Distortion, both Measurement and Orientation Distortions are pervasive. The study recommends the auditing of financial graphs, and urges preparers and users of annual reports to be wary of the possibility of graph distortion.
