Fatores visuais de design e sua influência nos valores de compra do consumidor

Este artigo explora o tema das experiências dos consumidores nos ambientes físicos oferecidos pelas empresas de serviços, avaliando o impacto de fatores visuais de design sobre a percepção de valor por parte dos clientes de um ponto de venda com autosserviço. Foram identificados os valores de compra dos usuários e as características de design percebidas no âmbito do varejo de autosserviço, envolvendo leiaute, sinalização e iluminação presentes no ambiente. O valor de compra, considerado uma resposta interna do consumidor ao ambiente de varejo, incluiu dimensões utilitárias e hedônicas. O método aplicado foi o cross-sectional survey, com a aplicação de questionário a 274 estudantes universitários, os quais manifestaram sua percepção de três diferentes livrarias com autoatendimento, ilustradas por fotos. Os resultados obtidos apontaram quatro características de design com influência significativa na formação de valor de compra dos consumidores sob a perspectiva utilitária e hedônica.

Design Digital: Do traço ao pixel

Neste artigo pretende-se compreender a aversão que designers (e arquitectos, inclusive) sentem verdadeiramente em relação “ao computador”. Se de um modo ele é um excelente parceiro aceite por todos, simultaneamente, é com muita apreensão que se programam currículos de disciplinas universitárias para que os alunos aprendam as características projectuais do design, desenvolvam capacidade criativa (inteligência no uso de recursos para a produção de conceitos ou objectos) usando o computador sistematicamente, ou seja, não apenas como uma ferramenta de desenho, mas também de projecto (design). Os automatismos continuam a ser os monstros de hoje, porém, como aqui defendemos, os computadores sempre projectaram sombra humana, são “apenas” máquinas hipermédias que recorrem a existentes tecnologias para, supostamente, criarem novas mais transparentes na relação homem-máquina.

The Experience of the Religious through Silent Moving Image and the Silence of Bill Viola's Passions

With the creationof the moving image at the end of the 19th century a new way of representing and expressing the Religious was born. The cinema industry rapidly understood that film has a powerful way to attract new audiences and transformed the explicit religious message into an implicit theological discourse of the fictional film. Today, the concept of "cinema" needs to be rethought and expanded, as well as the notion of "tTranscendental" since the strong reality effect of the film can allow a true religious experience for the spectator.

O trabalho em equipas docentes e o desenvolvimento da Educação Física

RESUMO: O sucesso das respostas aos novos desafios, exigências e expectativas que, nos dias de hoje, recaem sobre a escola, parece depender da concepção das estratégias organizacionais que globalmente a escola define, tendo em conta as características do contexto e das populações que serve. Depende por isso do modo como os actores chave se organizam e trabalham. Os modos de entender o trabalho docente em equipa prenunciam formas de entender a acção educativa e de conduzir a aprendizagem dos alunos. Tomando como ponto de partida as nossas experiências profissionais, este trabalho constitui uma reflexão sobre as possibilidades de desenvolvimento da Educação Física, baseada na escola e sustentada na organização do trabalho dos seus professores. Elaborando uma síntese dos principais problemas do seu desenvolvimento discutem-se as possibilidades e as vantagens da organização do trabalho dos professores em equipas, num contexto organizacional marcado por avanços e retrocessos nos processos de descentralização e atribuição de autonomia às escolas. Enquadra-se a organização do trabalho docente no âmbito das culturas de escola. Revisita-se o conceito de trabalho em equipa, distinguindo-o da simples participação nas estruturas da escola, realçando a sua importância na construção e gestão de conhecimento profissional através do estabelecimento de parcerias sinérgicas, onde o desempenho de papéis de liderança tem uma enorme importância. ABSTRACT: Successful responses to the new challenges, demands and expectations that currently are ascribed to schools seem to depend on the design of organizational strategies that broadly define the school, taking into account the characteristics of its context and the population it serves. Therefore, their success depends on how the key players are organized and work. The ways of perceiving the teaching team work forecast the ways of understanding the educational activity and how to lead learning. Starting from our own professional experience, this study is a reflection on the school based development of physical education, sustained by the organization of their teachers’ work. On organizing a summary of the major problems found in the development of this subject, we discuss the feasibilities and the gains got from the organization of teachers' teamwork, in an organizational context marked by promises and setbacks in the processes of decentralization and schools autonomy. The organization of teaching is to be seen as part of the school culture. We review the concept of teamwork as distinct from mere participation in the structures of the school, and its importance in the construction and management of professional knowledge will be highlighted by the establishment of synergistic partnerships, in which the performance of leadership roles is of the greatest importance. RÉSUMÉ: Le succès des réponses aux nouveaux défis, les exigences et les attentes que dans ces jours, s’accomplissent sur l'école, semble dépendre de la conception des stratégies d'organisation qui définit de façon générale l'école, en tenant compte des caractéristiques du contexte et des populations qu'elle dessert. Tout cela dépend donc de la façon dont les acteurs principaux sont organisés et travaillent. Les façons de comprendre l'équipe pédagogique démontrent des formes de comprendre l'activité éducative et de conduire à l'apprentissage des élèves. En prenant comme point de départ nos expériences professionnelles, ce travail est une réflexion sur le potentiel de développement de l'Éducation Physique, dépendante de l'école et soutenue dans l'organisation du travail de leurs enseignants. En préparant une synthèse des principaux problèmes de leur développement, on discute les possibilités et les avantages de l'organisation du travail des enseignants dans les équipes, dans un contexte organisationnel marqué par des avancées et des reculs dans le processus de décentralisation et l'accomplissement de l'autonomie aux écoles. On encadre l'organisation du travail des enseignants dans le champ des cultures de l’école. On revoit le concept du travail en équipe, en le distinguant de la simple participation dans les structures de l'école, en soulignant son importance dans la construction et gestion des connaissances professionnelles à travers l'établissement de partenariats synergiques, où les rôles de leadership joue un rôle d'une grande importance.

The impact of improvement of water supply and sanitation facilities on diarrhea and intestinal parasites: a Brazilian experience with children in two low-income urban communities

During the second half of 1986 the impact of the improvement of water supply and excreta disposal facilities on diarrheal diseases and intestinal parasitosis was studied in 254 children up to six years of age from two favelas (shanty towns) of Belo Horizonte, Brazil. The estimated incidence of diarrhea was 6.2 episodes/child year and the estimated period prevalence reached 31.0 episode days/ child/ year. The point prevalence of parasitosis was 70.7% (Ascaris lumbricoides: 55.4%, Trichuris trichiura: 19.6%, Giardia lamblia: 17.9%). The estimated prevalence of diarrhea decreased with improvement of water supply and sanitation facilities to 45% and 44% respectively, but no statistically significant impact was observed in the case of parasitosis. School education and weaning practice were found to be other important determinants of diarrhea.

O design do manual escolar

O manual escolar, pelas suas características, é um produto de design gráfico, disciplina que tardou a desenvolver-se em Portugal. Após o 25 de Abril, as editoras escolares expandiram-se, e a globalização do ensino teve como consequência o aumento do número de manuais escolares. O desenvolvimento do design gráfico está intimamente ligado ao desenvolvimento da tecnologia informática, contribuindo fortemente para a alteração das características do manual escolar, sendo a mais notória a importância dada à imagem como portadora de informação. Sem investigação que suporte o seu actual formato, nem formação dos professores que permita explorar as suas novas potencialidades, interrogamo-nos sobre a sua eficácia. O campo da teoria da imagem é vasto e a sua aplicação, quer na realização, quer na exploração pedagógica do manual escolar, exige alguma sistematização que procuramos apresentar.

Design of improved rail-to-rail low-distortion and low-stress switches in advanced CMOS technologies

This paper describes the efficient design of an improved and dedicated switched-capacitor (SC) circuit capable of linearizing CMOS switches to allow SC circuits to reach low distortion levels. The described circuit (SC linearization control circuit, SLC) has the advantage over conventional clock-bootstrapping circuits of exhibiting low-stress, since large gate voltages are avoided. This paper presents exhaustive corner simulation results of a SC sample-and-hold (S/H) circuit which employs the proposed and optimized circuits, together with the experimental evaluation of a complete 10-bit ADC utilizing the referred S/H circuit. These results show that the SLC circuits can reduce distortion and increase dynamic linearity above 12 bits for wide input signal bandwidths.

Optimal design of piezolaminated structures using B-spline strip finite element models

A package of B-spline finite strip models is developed for the linear analysis of piezolaminated plates and shells. This package is associated to a global optimization technique in order to enhance the performance of these types of structures, subjected to various types of objective functions and/or constraints, with discrete and continuous design variables. The models considered are based on a higher-order displacement field and one can apply them to the static, free vibration and buckling analyses of laminated adaptive structures with arbitrary lay-ups, loading and boundary conditions. Genetic algorithms, with either binary or floating point encoding of design variables, were considered to find optimal locations of piezoelectric actuators as well as to determine the best voltages applied to them in order to obtain a desired structure shape. These models provide an overall economy of computing effort for static and vibration problems.

The development of a scale to measure concepts of schizophrenia: experience among Brazilian psychiatrists

INTRODUCTION: Among psychiatric disorders schizophrenia is often said to be the condition with the most disputed definition.The Bleulerian and Schneiderian approaches have given rise to diagnostic formulations that have varied with time and place. Controversies over the concept of schizophrenia were examined within European/North American settings in the early 1970s but little has since been reported on the views of psychiatrists in developing countries. In Brazil both concepts are referred to in the literature. A scale was developed to measure adherence to Bleulerian and Schneiderian concepts among psychiatrists working in S. Paulo. METHODOLOGY: A self-reported questionnaire comprising seventeen visual analogue-scale statements related to Bleulerian and Schneiderian definitions of Shizophrenia, plus sociodemographic and training characteristics, was distributed to a non-randomised sample of 150 psychiatrists. The two sub-scales were assessed by psychometric methods for internal consistency, sub-scale structure and test-retest reliability. Items selected according to internal consistency were examined by a two-factor model exploratory factor analysis. Intraclass correlation coefficients described the stability of the scale. RESULTS: Replies were received from 117 psychiatrists (mean age 36 (SD 7.9)), 74% of whom were made and 26% female. The Schneiderian scale showed better overall internal consistency than the Bleulerian scale. Intra-class correlation coefficients for test-retest comparisons were between 0.5 and 0.7 for Schneiderian items and 0.2 and 0.7 for Bleulerian items. There was no negative association between Bleulerian and Schneiderian scale scores, suggesting that respondents may hold both concepts. Place of training was significantly associated with the respondent's opinion; disagreement with a Bleulerian standpoint predominated for those trained at the University of S. Paulo. CONCLUSIONS: The less satisfactory reliability for the Bleulerian sub-scale limits confidence in the whole scale but on the other hand this questionnaire contributes to the understanding of the controversy over Bleulerian and Schneiderian models for conceptualisation of schizophrenia, the former requiring more inference and therefore being prone to unreliability.

Design of a sea-level tsunami detection network for the Gulf of Cadiz

The devastating impact of the Sumatra tsunami of 26 December 2004, raised the question for scientists of how to forecast a tsunami threat. In 2005, the IOC-UNESCO XXIII assembly decided to implement a global tsunami warning system to cover the regions that were not yet protected, namely the Indian Ocean, the Caribbean and the North East Atlantic, the Mediterranean and connected seas (the NEAM region). Within NEAM, the Gulf of Cadiz is the more sensitive area, with an important record of devastating historical events. The objective of this paper is to present a preliminary design for a reliable tsunami detection network for the Gulf of Cadiz, based on a network of sea-level observatories. The tsunamigenic potential of this region has been revised in order to define the active tectonic structures. Tsunami hydrodynamic modeling and GIS technology have been used to identify the appropriate locations for the minimum number of sea-level stations. Results show that 3 tsunameters are required as the minimum number of stations necessary to assure an acceptable protection to the large coastal population in the Gulf of Cadiz. In addition, 29 tide gauge stations could be necessary to fully assess the effects of a tsunami along the affected coasts of Portugal, Spain and Morocco.

MDAI: Model based Design in Automobile Industry

It is proposed a new approach based on a methodology, assisted by a tool, to create new products in the automobile industry based on previous defined processes and experiences inspired on a set of best practices or principles: it is based on high-level models or specifications; it is component-based architecture centric; it is based on generative programming techniques. This approach follows in essence the MDA (Model Driven Architecture) philosophy with some specific characteristics. We propose a repository that keeps related information, such as models, applications, design information, generated artifacts and even information concerning the development process itself (e.g., generation steps, tests and integration milestones). Generically, this methodology receives the users' requirements to a new product (e.g., functional, non-functional, product specification) as its main inputs and produces a set of artifacts (e.g., design parts, process validation output) as its main output, that will be integrated in the engineer design tool (e.g. CAD system) facilitating the work.
