Foram buscadas referências históricas relacionadas ao ofício da pintura de letras, a fim de comparações com o discurso dos pintores atuais, do qual foram apropriados elementos que, juntamente com a teoria do design e da tipografia, foram utilizados para a construção de um sistema de análise, que incluiu entre suas diretrizes a produção de dados quantitativos que permitam identificar os recursos mais recorrentes que constituem a linguagem gráfica pesquisada.

Publicidad y cultura : una relación de carácter internacional

En el trabajo que nos ocupa analizaremos la relación entre diversos ámbitos culturales y la publicidad internacional audiovisual. En la publicidad audiovisual, como la televisiva, las imágenes cargadas de valor simbólico son determinantes para el posicionamiento de una marca y para llegar a la mente del consumidor. A lo largo del estudio relacionaremos el simbolismo de estas imágenes con la mitología y la música para acercarnos a emociones universales que faciliten la relación entre la marca y el consumidor, o bien, entre el spot publicitario y el espectador. En el ámbito internacional, donde se encuentran personas con identidades culturales muy diferentes, y desde una perspectiva comunicacional sería de gran utilidad conocer aspectos comunes en la mente de todo ser humano que favoreciesen la estandarización y sus consecuentes sinergias.

Análise do processo de formulação de uma proposta de regulamentação de propagandas de alimentos: um estudo de caso

O consumo de alimentos processados tem crescido mundialmente e esse aumento tem sido relacionado em parte, pelas estratégias de marketing utilizadas pelas indústrias alimentícias que tem como objetivo aumentar as vendas e expandir o mercado consumidor. Segundo documento Recomendações da Consulta de Especialistas da Organização Pan-Americana da Saúde sobre a Promoção e a Publicidade de Alimentos e Bebidas Não Alcoólicas para Crianças nas Américas, a publicidade televisiva é a forma mais utilizada de marketing de alimentos para crianças e está associada a maior preferência e aumentos nos pedidos de compra de alimentos e bebidas com elevado teor de gordura, açúcar e sal. No âmbito da discussão mais recente sobre a possível influência da propaganda de alimentos na epidemia mundial de obesidade e doenças crônicas, o governo brasileiro, por meio da Agência Nacional de Vigilância Sanitária (ANVISA), formulou uma proposta de Regulamento Técnico que normatiza os termos das atividades publicitárias e que se concretizou na Resolução da Diretoria Colegiada n 24 de 2010 (RDC24/2010). Logo após sua publicação, grupos de interesse empresarial entraram na justiça e obtiveram diversas liminares que suspenderam a aplicação da RDC 24/2010 com base em parecer contrário da Advocacia Geral da União (AGU). O debate sobre ações regulatórias no campo da alimentação e nutrição como estratégia de controle e prevenção da obesidade envolve diversos atores sociais e opiniões bastante distintas e antagônicas, principalmente quando se trata dos argumentos do grupo de indivíduos que acredita na regulamentação da publicidade como uma forma de promover a saúde versus os argumentos contrários dos setores econômicos ligados ao tema a ser regulado. Neste sentido, este trabalho teve a intenção de descrever como e por que, neste processo, algumas práticas se estabeleceram no cotidiano das instituições e identificar os embates, argumentos e conflitos de interesses que apareceram nas discussões a respeito da formulação da resolução. Para isso, foi feita, primeiramente, análise documental de todo o processo de formulação, através de arquivos institucionais, documentos, pareceres, relatórios, entre outros. Posteriormente, foram identificados e caracterizados os sujeitos que participaram do processo e em seguida, realizadas entrevistas semi-estruturadas com atores chaves. Foram encontradas duas teses centrais no debate em torno da formulação da resolução: a primeira, se o Estado deve estabelecer uma regulamentação sobre publicidade de alimentos e a segunda diz respeito à competência legal da ANVISA em exercer o papel regulador sobre a propaganda de alimentos. As disputas em torno destas duas teses e os argumentos que se apresentaram para defendê-las são evidentemente incomensuráveis entre si, não havendo esperança de acordo entre as partes. O caso descrito elegeu a ANVISA como o território da disputa e a aparente maioria no jogo democrático desta arena mostrou-se ineficaz diante da captura pelo questionamento da pertinência desta Agência para função de regular a publicidade de alimentos.

Propaganda Partidária Gratuita : seus dilemas e implicações sobre os partidos políticos e a comunicação política brasileira

Este trabalho tem como objetivo empreender um estudo inicial sobre a Propaganda Partidária Gratuita, espaço disponibilizado pelo Estado brasileiro aos partidos políticos para que estes possam apresentar a si próprios e divulgar seus programas políticos. Segundo o levantamento feito para este trabalho, trata-se de um caso único no mundo, mas que vem sendo abordado apenas marginalmente pela Ciência Política do país. Dada a proximidade com o horário eleitoral, a análise foi feita tendo como base a literatura sobre campanhas políticas, de modo a verificar se processos a ela relacionados (em especial o de declínio partidário e a personalização da política) podem se aplicar ao objeto em questão. Para tanto, realizou-se um levantamento empírico das edições exibidas entre 2002 e 2007 de cinco siglas: PFL/DEM, PMDB, PSB, PSDB e PT. Nestes, foram observadas diferentes variáveis, como ênfases discursivas e temática dominante, bem como o conteúdo apresentado. Em função destes dados, oferece-se uma visão de como os programas são utilizados de modo geral e por cada partido, oferecendo ainda uma tipologia sobre seus usos.

Dead-time minimisation using active voltage control gate drive for high-power IGBT converters

High-power converters usually need longer dead-times than their lower-power counterparts and a lower switching frequency. Also due to the complicated assembly layout and severe variations in parasitics, in practice the conventional dead-time specific adjustment or compensation for high-power converters is less effective, and usually this process is time-consuming and bespoke. For general applications, minimising or eliminating dead-time in the gate drive technology is a desirable solution. With the growing acceptance of power electronics building blocks (PEBB) and intelligent power modules (IPM), gate drives with intelligent functions are in demand. Smart functions including dead time elimination/minimisation can improve modularity, flexibility and reliability. In this paper, a dead-time minimisation using Active Voltage Control (AVC) gate drive is presented. © 2012 IEEE.

多视点学习条件下场景内在参照系的建立

The aim of the present study was to investigate whether people can establish two oblique spatial reference directions to represent objects’ locations in memory. Participants learned a layout of objects from two oblique viewpoints (0º and 225º) and made judgments of relative direction (“Imagine you are standing at X, facing Y, please point to Z”). Experiments 1 to 3 showed that performance in pointing were better at either one of the familiar imagined headings (0º and 225º) in most of the participants even when they were instructed to learn the layout along their actual heading at both learning directions, and when their actual headings at the test were the same as the imagined headings. Experiments 4 to 6 showed performance in pointing could be equivalent at the two familiar imagined headings for significant number of the participants when participants learned two different set of objects occupied at the same locations from the two learning viewpoints, and when participants learned the same layout of objects together with two different layouts from the two learning viewpoints. These results suggest that the orientation dependent performance in Experiments 1 to 3 cannot be attributed to the possibility that participants had formed two oblique spatial reference directions during learning but only used one of them during testing. Experiments 7 and 8 further showed that the performance of pointing at the two familiar viewpoints were significantly different when participants experienced one viewpoint by learning the actual layout and the other viewpoint by learning the map of the same layout, and when participants experienced two viewpoints alternatively over the ten times of learning sessions. All these results strongly suggest that people establish only one spatial reference system to represent locations of objects when they learn the same layout in the same background from two oblique viewpoints.

A multilevel algorithm for force-directed graph drawing

We describe a heuristic method for drawing graphs which uses a multilevel technique combined with a force-directed placement algorithm. The multilevel process groups vertices to form clusters, uses the clusters to define a new graph and is repeated until the graph size falls below some threshold. The coarsest graph is then given an initial layout and the layout is successively refined on all the graphs starting with the coarsest and ending with the original. In this way the multilevel algorithm both accelerates and gives a more global quality to the force- directed placement. The algorithm can compute both 2 & 3 dimensional layouts and we demonstrate it on a number of examples ranging from 500 to 225,000 vertices. It is also very fast and can compute a 2D layout of a sparse graph in around 30 seconds for a 10,000 vertex graph to around 10 minutes for the largest graph. This is an order of magnitude faster than recent implementations of force-directed placement algorithms.

A multilevel algorithm for force-directed graph-drawing

We describe a heuristic method for drawing graphs which uses a multilevel framework combined with a force-directed placement algorithm. The multilevel technique matches and coalesces pairs of adjacent vertices to define a new graph and is repeated recursively to create a hierarchy of increasingly coarse graphs, G0, G1, …, GL. The coarsest graph, GL, is then given an initial layout and the layout is refined and extended to all the graphs starting with the coarsest and ending with the original. At each successive change of level, l, the initial layout for Gl is taken from its coarser and smaller child graph, Gl+1, and refined using force-directed placement. In this way the multilevel framework both accelerates and appears to give a more global quality to the drawing. The algorithm can compute both 2 & 3 dimensional layouts and we demonstrate it on examples ranging in size from 10 to 225,000 vertices. It is also very fast and can compute a 2D layout of a sparse graph in around 12 seconds for a 10,000 vertex graph to around 5-7 minutes for the largest graphs. This is an order of magnitude faster than recent implementations of force-directed placement algorithms.

A systematic methodology to assess the impact of human factors in ship design

Evaluating ship layout for human factors (HF) issues using simulation software such as maritimeEXODUS can be a long and complex process. The analysis requires the identification of relevant evaluation scenarios; encompassing evacuation and normal operations; the development of appropriate measures which can be used to gauge the performance of crew and vessel and finally; the interpretation of considerable simulation data. Currently, the only agreed guidelines for evaluating HFs performance of ship design relate to evacuation and so conclusions drawn concerning the overall suitability of a ship design by one naval architect can be quite different from those of another. The complexity of the task grows as the size and complexity of the vessel increases and as the number and type of evaluation scenarios considered increases. Equally, it can be extremely difficult for fleet operators to set HFs design objectives for new vessel concepts. The challenge for naval architects is to develop a procedure that allows both accurate and rapid assessment of HFs issues associated with vessel layout and crew operating procedures. In this paper we present a systematic and transparent methodology for assessing the HF performance of ship design which is both discriminating and diagnostic. The methodology is demonstrated using two variants of a hypothetical naval ship.

Comfort Care Rounds: A Staff Capacity-Building Initiative in Long-Term Care Homes

This article reports a pilot evaluation of Comfort Care Rounds (CCRs)-a strategy for addressing long-term care home staff's palliative and end-of-life care educational and support needs. Using a qualitative descriptive design, semistructured individual and focus group interviews were conducted to understand staff members' perspectives and feedback on the implementation and application of CCRs. Study participants identified that effective advertising, interest, and assigning staff to attend CCRs facilitated their participation. The key barriers to their attendance included difficulty in balancing heavy workloads and scheduling logistics. Interprofessional team member representation was sought but was not consistent. Study participants recognized the benefits of attending; however, they provided feedback on how the scheduling, content, and focus could be improved. Overall, study participants found CCRs to be beneficial to their palliative and end-of-life care knowledge, practice, and confidence. However, they identified barriers and recommendations, which warrant ongoing evaluation.

A Travel Optimization System for Academic Environments

Carpooling initiated in America in the 1970s due to the oil crisis. However, over the past years, carpooling has increased significantly across the world. Some countries have created a High Occupancy Vehicle (HOV) lane to encourage commuters not to travel alone. In additional, carpool websites has been developed to facilitate the connection between the commuters, making it possible to create a compatible match in a faster and efficient manner. This project focuses on carpooling, especially in an academic environment since younger people are more likely to choose carpool. Initially, an intense research was made to examine carpool studies that occurred all over the world, following with a research of higher education institutes that use carpooling as a transportation mode. Most websites created carpools by targeting people from a specific country. These commuters have different origins and destinations making it more complicated to create compatible matches. The objective of this project is to develop a system helping teachers and students from an academic environment to create carpool matches. This objective makes it easier to create carpools because these students and teachers have the same destination. During the research, it was essential to explore, as many as possible, existing carpool websites that are available across the world. After this analysis, several sketches were made to develop the layout and structure of the web application that’s being implemented throughout the project. Once the layout was established, the development of the web application was initiated. This project had its ups and downs but it accomplished all the necessary requirements. This project can be accessed on the link: http://ipcacarpool.somee.com. Once the website was up and running, a web-based survey was developed to study the reasons that motivate people to consider carpooling as an alternative to driving alone. To develop this survey was used a tool called Survey Planet. This survey contained 408 respondents, which 391 are students and 17 are teachers. This study concludes that a majority of the respondents don’t carpool, however they will consider carpooling if there was a dedicated parking space. A majority of the respondents that carpool initiated less than a year ago, indicating that this mean of transportation is recent.
