Gaze and power. A post-structuralist interpretation on Perseus’ myth

Gaze hierarchizes, manages and labels reality. Then, according to Foucault, gaze can be understood as a practice of power. This paper is inspired by his theories, and it applies them to one of the most powerful symbolic spheres of Western culture: Greek Myths. Notions such as visibility, invisibility and panopticism bring new light into the story of Perseus and Medusa, and they enable a re-reading of this Myth focused on the different ways of power that emerge from the gaze.

Relation of the work of the artist Antonio Lopez with the photography. Methods of a teacher rejected as a professor

In 1966 the artist Antonio Lopez was rejected for the chair in “Preparatorio de colorido” (Preparatory Colouring) by the San Fernando School of Fine Arts where he himself presented his work Nevera de hielo (Ice Box). After 5 years as a “stand in” for this post he left the Institution. This article analyzes the circumstances and proof of a decade where there appears to be evidence of a definite change in his work, more toward Realism, uncomfortable in a system that maintained with difficulty the traditional academic model copy, and incompatible with, in those years was imposed by Spain. At the same time his relation with photography conditioned by the theoretical thoughts of the artist, and his work methods also are analyzed in this article.

The Rhetorical Construction of Corporate Logos

This research is set in the context of today’s societies, in which the corporate visual symbology of a business, corporation or institution constitutes an essential way to transmit its corporate image. Traditional discursive procedures can be discovered in the development of these signs. The rhetorical strategies developed by the great classical authors appear in the logo-symbols expressing the corporate values of today’s companies. Thus, rhetoric is emerging once again in the sense it had many centuries ago: A repertory of rules that, paradoxically, standardizes the deviations of language and whose control is synonymous with power. The main objective of this study is to substantiate the rhetorical construction of logos using as a model of analysis the classical process of creating discourse. This involves understanding logos as persuasive discourses addressed to a modern audience. Our findings show that the rhetorical paradigm can be considered as a creative model for the con­struction of an original logo consistent with a company’s image.

Micro-environmental conditions modulate protein secretion and infectivity of the Trichinella spiralis L1 larva

After digestion of infected meat the free L1 of Trichinella spp. penetrate the intestinal mucosa where they moult to the mature adult stage. We have used proteomics to identify changes in protein secretion during in vitro culture of free T. spiralis muscle larvae under different environmental conditions, and to correlate these changes with their infectivity in mice. Muscle larvae were cultured in different media (RPMI-1640, C-199 and HBSS) under conditions of anaerobiosis, microaerobiosis and in 5% CO(2) at 37 degrees C. Following incubation the larval excretory/secretory proteins were analysed by two-dimensional gel electrophoresis and the larvae were used to orally infect naïve CD1 mice. For all culture media tested, infectivity of the L1 was preserved following incubation in anaerobic conditions. In contrast, the infectivity of worms cultured in nutrient-rich media was almost completely abolished in both microaerobiosis and in the presence of 5% CO(2). Some infectivity was retained in poor or reduced culture media. Comparative analysis of larval infectivity and protein secretion showed that loss of infectivity correlated with the appearance of non-tyvelosylated proteins that in turn may be related to the onset of moulting.

A vivência emocional dos enfermeiros nos cenários da prestação de cuidados ao doente oncológico: o caso dos enfermeiros de um serviço de oncologia médica do Instituto Português de Oncologia de Lisboa Francisco Gentil, E.P.E.

Com a presente investigação pretendemos conhecer a vivência das emoções dos enfermeiros nos cenários da prestação de cuidados ao doente oncológico e simultaneamente contribuir para uma melhoria das práticas de intervenção e de gestão emocional em enfermagem nos contextos de trabalho em Oncologia, procurando dar resposta à pergunta inicial de investigação: Qual a vivência emocional dos enfermeiros nos cenários da prestação de cuidados ao doente oncológico? Nas opções metodológicas optámos pelo paradigma qualitativo, onde a entrevista narrativa foi a técnica privilegiada de recolha de informação, tendo permitido compreender com profundidade a forma como os enfermeiros vivem a prestação de cuidados ao doente oncológico. As experiências emocionais consideradas mais marcantes foram na generalidade aquelas que mais penosas se constituíram para os entrevistados, relacionadas com uma relação mais próxima e profunda com o doente e com situações de morte e sofrimento. Consequentemente os sentimentos e emoções referidos foram na sua maioria negativa. Na prática de cuidar do doente oncológico verificou-se a influência marcada dos mitos sociais e pessoais associados à doença cancro, tendo sido reconhecida de forma global a complexidade e especificidade inerentes a esta prestação de cuidados, tão gratificante, quanto desgastante. O uso de mecanismos de gestão das experiências emocionais refletiu-se no recurso a estratégias pessoais e externas, usadas na sua maioria com o objetivo de o desgaste emocional. Foram sugeridas várias medidas de intervenção organizacional no reconhecer uníssono da necessidade de acompanhamento e suporte por parte da organização de saúde. Os resultados desta investigação acrescentam assim todo um conjunto de novos dados que ajudam na compreensão da problemática da vivência emocional dos enfermeiros, na certeza de que esta melhorará a prestação de cuidados ao doente oncológico, com consequente otimização organizacional. /ABSTRACT - With this present investigation we intend to study the emocional life of nurses while providing health care to oncological patients and simultaneously contribute to an improvement of the intervention and emotional management practices in nursing in the contexts of working in Oncology, trying to answer the initial question of the inquiry: What is the emotional life of nurses in health care scenerjy to oncological patients? As far as the methodology is concerned we chose the qualitative paradigm, in which the narrative interview was the privileged technique to gather information. That allowed us to deeply understand the way nurses live the providing of health care to the oncological patient, their emotional experiences, what they feel and express, what moves and consumes them, as well as the forms of emotional management. The most striking emotional experiences have, in general, been those considered most painful by the interviewed nurses, usually related to a closer and deeper relation with the patient and situations of death and suffering. The consequent feelings and emotions have been mostly negative. Health care provided to oncologic patients is strongly influenced by social and personal myths related to cancer and both the complexity and specificity inherent to this kind of health care has been acknowledged as rewarding, as consuming. The use of means of emotional management is visible in the resource to personal and external strategies, used to diminish the emotional consumption. They have also suggested some measures of organizational intervention in the unison recognition of the need of accompaniment and support from the health care institution. The results of this investigation, thus add whole a set of new data that helps in the understanding of the problematic of the emotional life of nurses, in the certainty that this will improve the providing of care to the oncolologically sick person, with consequent organizational optimization.

Contributos operários para a educação popular em Portugal. O caso da Fábrica de Conservas S. Francisco, da empresa Júdice Fialho, em Portimão

Este artigo debruça-se sobre o período histórico do pós revolução de abril de 1974, a abril de 1976, usando como quadro concetual a noção de educação popular e como contexto empírico a fábrica de conservas “S. Francisco” da empresa Júdice Fialho, localizada na cidade de Portimão. Pretende abrir algumas ideias para perceber de que forma o operariado se organizou em comissões de base, para lutar em defesa de melhores condições de vida e de trabalho. Pretende, ainda, compreender os mecanismos usados para desenvolver um processo educativo de aprendizagem autónoma e emancipatória relativa ao trabalho e à vida social.

A importância pedagógica das artes visuais no 2º ciclo do Ensino Básico: actividades desenvolvidas com estudantes do 6º ano na Escola Dr. António Francisco Colaço em Castro Verde

O objetivo deste trabalho teve como principal finalidade incluir a interpretação das obras de arte, nas suas diferentes dimensões, como componentes integradoras do conhecimento nas artes visuais. O contacto com a arte é um dos propósitos implícitos nesta proposta. A convicção da importância do contacto dos alunos com a obra de arte. Da educação estética na formação integral do ser humano e na apetência pelo prazer das artes no seu contexto, assim como a constatação da ausência do diálogo com a obra de arte no programa da disciplina, conduziu-nos à elaboração, experimentação e reflexão sobre um conjunto de atividades de apreciação estética que envolveram a análise e interpretação de obras de arte, bem como com a transmissão de conhecimentos de história de arte, à execução de trabalhos de expressão plástica. As obras de arte, prestam-se a uma pluralidade de interpretações, desenvolvem a sensibilidade e a imaginação, desempenhando por isso um papel importante na experiência pessoal dos indivíduos. O convívio com a arte é um dos modos mais eficazes para a formação da personalidade e para a integração do indivíduo nos valores superiores da humanidade. É hoje quase lugar-comum a referência à importância das atividades expressivos-artísticas no desenvolvimento “harmonioso” da pessoa humana. Dada a natureza prática das atividades de desenho, de pintura e de criatividade, envolvem os alunos e criam um ambiente propício para a aprendizagem. Após a análise e reflexão dos resultados desta experiência, o estudo permite concluir que os alunos estão recetivos a este tipo de experiências e aprendizagens. O diálogo com a obra de arte, associado à transmissão de conhecimentos de história de arte e à realização de trabalhos de expressão plástica, contribui para o aumento do entusiasmo e motivação nos alunos, para o desenvolvimento das suas capacidades de perceção e interpretação de significados, para a superação de dificuldades nas suas produções plásticas e para o aumento da confiança e autoestima face às suas capacidades de expressão, o que torna fundamental a introdução deste tipo de atividades nas nossas atuais práticas letivas.

Francisco Fernandes Lopes (1884-1969), historiador do Algarve: contributo para a historiografia henriquina

São ainda muito incipientes os estudos sobre a vida e obra do médico olhanense Francisco Fernandes Lopes (1884-1969), uma das figuras mais interessantes do quadro cultural português da primeira metade do século XX. Na verdade, dificilmente poderemos caracterizá-lo apenas como “médico”, pois era um intelectual multifacetado e interessado nas mais diversas áreas do saber, assim como também é impossível descrevê-lo apenas como “olhanense”, pois a sua actividade intelectual extravasou largamente o âmbito local, regional e mesmo nacional. A presente dissertação, intitulada Francisco Fernandes Lopes (1884-1969), historiador do Algarve: contributo para a historiografia henriquina, tem dois objectivos principais, patentes no próprio título: compreender o homem, ou seja, elaborar um estudo biográfico sobre Fernandes Lopes, e analisar uma das suas facetas, a de historiador, mais concretamente no que concerne à sua obra acerca do Infante D. Henrique e a sua relação ao Algarve. No que respeita à biografia, pretende-se compreender a vida e obra de Francisco Fernandes Lopes através de uma análise concertada do seu percurso de vida, dos seus principais interesses e da sua actividade cultural e intelectual. Neste âmbito, é essencial ter em consideração que a vida de Fernandes Lopes se desenrolou mormente em Olhão, vila algarvia singular devido ao seu panorama arquitectónico único de açoteias, e que ele tanto se empenhou em divulgar, procurando que Olhão ocupasse um lugar de destaque no mapa do Algarve e, também, de Portugal. Relativamente à produção historiográfica tem particular destaque a temática henriquina, que foi a que mais ocupou Francisco Fernandes Lopes entre as décadas de 30 a 60 do século XX. Os seus estudos devem ser entendidos no âmbito de um período histórico muito específico – o Estado Novo – e tendo por base a evolução do pensamento historiográfico, assim como outros estudos similares e coetâneos que permitam formular uma comparação.

Identification of Potential Sources of Airborne Olea Pollen in the Southwest Iberian Peninsula

This study aims to determine the potential origin of Olea pollen recorded in Badajoz in the Southwest of the Iberian Peninsula during 2009–2011. This was achieved using a combination of daily average and diurnal (hourly) airborne Olea pollen counts recorded at Badajoz (south-western Spain) and Évora (south-eastern Portugal), an inventory of olive groves in the studied area and air mass trajectory calculations computed using the HYSPLIT model. Examining olive pollen episodes at Badajoz that had distinctly different diurnal cycles in olive pollen in relation to the mean, allowed us to identify three different scenarios where olive pollen can be transported to the city from either distant or nearby sources during conditions with slow air mass movements. Back trajectory analysis showed that olive pollen can be transported to Badajoz from the West on prevailing winds, either directly or on slow moving air masses, and from high densities of olive groves situated to the Southeast (e.g. Andalucía). Regional scale transport of olive pollen can result in increased nighttime concentrations of this important aeroallergen. This could be particularly important in Mediterranean countries where people can be outdoors during this time due to climate and lifestyle. Such studies that examine sources and the atmospheric transport of pollen are valuable for allergy sufferers and health care professionals because the information can be incorporated into forecasts, the outputs of which are used for avoiding exposure to aeroallergens and planning medication. The results of studies of this nature can also be used for examining gene flow in this important agricultural crop.

Comparison of Poaceae Pollen Counts Recorded at Sites in Portugal, Spain and the UK

The main aim of this study was to analyse the temporal and spatial variations in grass (Poaceae) pollen counts (2005–2011) recorded in Évora (Portugal), Badajoz (Spain) and Worcester (UK). Weekly average data were examined using nonparametric statistics to compare differences between places. On average, Évora recorded the earliest start dates of the Poaceae pollen seasons and Worcester the latest. The intensity of the Poaceae pollen season varied between sites, with Worcester usually recording the least and Évora the most grass pollen in a season. Mean durations of grass pollen seasons were 77 days in Évora, 78 days in Badajoz and 59 days in Worcester. Overall, longer Poaceae pollen seasons coincided with earlier pollen season start dates. Weekly pollen data, from March to September, from the three pollen-monitoring stations studied were compared. The best fit and most statistically significant correlations were obtained by moving Worcester data backward by 4 weeks (Évora, r = 0.810, p < 0.001) and 5 weeks (Badajoz,r = 0.849, p < 0.001). Weekly data from Worcester therefore followed a similar pattern to that of Badajoz and Évora but at a distance of more than 1,500 km and 4–5 weeks later. The sum of pollen recorded in a season was compared with monthly rainfall between January and May. The strongest positive relationship between season intensity and rainfall was between the annual sum of Poaceae pollen recorded in the season at Badajoz and Évora and total rainfall during January and February. Winter rainfall noticeably affects the intensity of Poaceae pollen seasons in Mediterranean areas, but this was not as important in Worcester.

Potential Sources of Airborne Alternaria spp. spores in South-west Spain

Fungi belonging to the genus of Alternaria are recognised as being significant plant pathogens, and Alternaria allergens are one of themost important causes of respiratory allergic diseases in Europe. This study aims to provide a detailed and original analysis of Alternaria transport dynamics in Badajoz, SW Spain. This was achieved by examining daily mean and hourly observations of airborne Alternaria spores recorded during days with high airborne concentrations of Alternaria spores (N100 s m−3) from 2009 to 2011, as well as four inventory maps of major Alternaria habitats, the overall synoptic weather situation and analysis of air mass transport using Hybrid Single Particle Lagrangian Integrated Trajectory model and geographic information systems. Land use calculated within a radius of 100 km from Badajoz shows that crops and grasslands are potentially the most important local sources of airborne Alternaria spores recorded at the site. The results of back trajectory analysis showthat, during the examined four episodes, the two main directions where Alternaria source areas were located were: (1) SW–W; and (2) NW–NE. Regional scale and long distance transport could therefore supplement the airborne catch recorded at Badajoz with Alternaria conidia originating from sources such as crops and orchards situated in other parts of the Iberian Peninsula.
