A series of performances in 'Translating Reviews from 1990: Art Forum'

Participation in group exhibition themed around the 25th anniversary of the Elba Benitez Gallery in Madrid. My work comprised a series of performances in which I translated reviews from the magazine Art Forum from 1990. The performances took place in various locations in London, throughout the run of the exhibition, and were streamed live to an iPad in the gallery in Madrid. I made audio visual recordings of the performances via the streaming media, which located me as the performer alongside the viewers in a single split image. These recordings were then archived in a shared folder held between the gallery and me, and which visitors to the exhibition could access when a performance was not taking place. The work extends my concerns with translation and performance, and with a consideration of how the mechanism of the gallery and the exhibition might be used to generate innovative viewing engagements facilitated by technology. The work also attempts to develop thinking and practice around the relationship between art works and their documentation - in this case the documentation and even its potential for distribution is generated as the work comes into being. The exhibition included works by Ignasi Aballí, Armando Andrade Tudela,Lothar Baumgarten, Carlos Bunga, Cabello/Carceller, Juan Cruz, Gintaras Didžiapetris, Fernanda Fragateiro, Hreinn Fridfinnsson, Carlos Garaicoa,Mario García Torres, David Goldblatt, Cristina Iglesias,Ana Mendieta, Vik Muniz, Ernesto Neto, Francisco Ruiz de Infante,Alexander Sokurov, Francesc Torres and Valentín Vallhonrat.

Consumerism in urban Russia in the 1880s and 90s: Exploring conceptions of time, space, and modernity through bicycle and watch advertisements

This paper discusses the urban consumer culture in Moscow and Petersburg during the 1880s and 1890s and uses the consumption of bicycles and watches as a lens through which to explore changing perceptions of time and space within the experience of modernity at the end of the nineteenth century. Specifically, I argue that the way in which consumers and merchants constructed a dialogue of meaning around particular objects; the way in which objects are consumed by a culture gives insight into the values, morals, and tenure of that culture. The paper preferences newspaper ads and photographs as the mouthpieces of merchants and consumers respectively as they constructed a dialogue in the language of consumerism, and explores the ways in which both parties sought to assign meaning to objects during the experience of modernity. I am particularly interested in the way consumers perform elements of cultural modernity in photographs and how these instances of performance relate to their negotiation of modernity. The paper takes as its focus large section of the urban Russian population, much of whom can traditionally be called “middle class” but whose diversity has led me to the adoption of the term “consumer community,” and whose makeup is described in detail. The paper contributes to the continuing scholarly discourse on the makeup of the middle class in Russia and the social boundaries of late tsarist society. It speaks to the the developing sensibilities and values of a generation struggling to define itself in a rapidly changing world, to the ways in which conceptualizations of public and private space, as well as feminine and masculine space were redefined, and to the developing visual culture of the Russian consumer society, largely predicated on the display of objects to signify socially desirable traits. Whereas other explorations of consumer culture and advertisements have portrayed the relationship between merchants and consumers as a one-sided monologue in which merchants convince consumers that certain objects have cultural value, I emphasis the dialogue between merchants and consumers, and their mutual negotiation of cultural meaning through objects.

Dimensão intercultural da linguagem não-verbal em contexto de sala de aula: um estudo com uma turma de espanhol

O presente relatório tem como principal objetivo desenvolver a competência da interculturalidade no âmbito da linguagem não-verbal de alunos portugueses, do 3º ciclo do ensino básico, com frequência à disciplina de Espanhol. A Linguagem não-verbal tem um contributo preponderante na comunicação e, quando há a pretensão de se conhecer outra cultura, é forçoso que se interpretem os diferentes sistemas onde cada indivíduo se integra e interage, porque comunicar eficazmente com o outro implica um conhecimento das estruturas simbólicas e dos códigos culturais intrínsecos, não só à cultura de um outro específico, mas também ao seu próprio contexto sociocultural, histórico-cultural e económico-cultural. Este trabalho faz apologia de um ensino intercultural que promova o diálogo entre culturas, sabendo-se de antemão que há representações que devem ser desconstruídas, bem como uma linguagem não-verbal específica que pode interferir na pragmática da interculturalidade. Trata-se de uma investigação-ação demarcada por dois momentos distintos: um primeiro estudo vocacionado para a consciencialização dos alunos de que a comunicação não-verbal é uma competência que se ensina e se aprende e um segundo estudo dedicado a aspetos culturais diferenciadores, entre Espanha e Portugal, na linguagem não-verbal , com enfoque nos gestos culturais e no tratamento do tempo. Os dados a analisar são: a transcrição de uma aula gravada, onde foram aplicados vários recursos audiovisuais e escritos consentâneos com as unidades programáticas, e as respostas a um questionário dirigido à turma de intervenção e a uma turma de nacionalidade espanhola que com ela colaborou. A implementação destas atividades/estratégias didáticas permitiu concluir que, por um lado, os alunos interpretam os diferentes códigos não -verbais à luz de uma perspetiva universal, por outro, há uma forte influência de estereótipos herdados e filtrados, a partir de diferentes marcos histórico-temporais. Este estudo sobre o não- verbal também se traduziu num alicerce bastante hábil para motivar à aprendizagem em geral e para enriquecer o conhecimento sobre a cultura do outro e a sua própria cultura, através da aquisição de códigos não- verbais comunicativo-funcionais.

INTEGRATED THRESHOLD-ACTIVATED FEEDBACK MICROSYSTEM FOR REAL-TIME CHARACTERIZATION, SENSING AND TREATMENT OF BACTERIAL BIOFILMS

Biofilms are the primary cause of clinical bacterial infections and are impervious to typical amounts of antibiotics, necessitating very high doses for treatment. Therefore, it is highly desirable to develop new alternate methods of treatment that can complement or replace existing approaches using significantly lower doses of antibiotics. Current standards for studying biofilms are based on end-point studies that are invasive and destroy the biofilm during characterization. This dissertation presents the development of a novel real-time sensing and treatment technology to aid in the non-invasive characterization, monitoring and treatment of bacterial biofilms. The technology is demonstrated through the use of a high-throughput bifurcation based microfluidic reactor that enables simulation of flow conditions similar to indwelling medical devices. The integrated microsystem developed in this work incorporates the advantages of previous in vitro platforms while attempting to overcome some of their limitations. Biofilm formation is extremely sensitive to various growth parameters that cause large variability in biofilms between repeated experiments. In this work we investigate the use of microfluidic bifurcations for the reduction in biofilm growth variance. The microfluidic flow cell designed here spatially sections a single biofilm into multiple channels using microfluidic flow bifurcation. Biofilms grown in the bifurcated device were evaluated and verified for reduced biofilm growth variance using standard techniques like confocal microscopy. This uniformity in biofilm growth allows for reliable comparison and evaluation of new treatments with integrated controls on a single device. Biofilm partitioning was demonstrated using the bifurcation device by exposing three of the four channels to various treatments. We studied a novel bacterial biofilm treatment independent of traditional antibiotics using only small molecule inhibitors of bacterial quorum sensing (analogs) in combination with low electric fields. Studies using the bifurcation-based microfluidic flow cell integrated with real-time transduction methods and macro-scale end-point testing of the combination treatment showed a significant decrease in biomass compared to the untreated controls and well-known treatments such as antibiotics. To understand the possible mechanism of action of electric field-based treatments, fundamental treatment efficacy studies focusing on the effect of the energy of the applied electrical signal were performed. It was shown that the total energy and not the type of the applied electrical signal affects the effectiveness of the treatment. The linear dependence of the treatment efficacy on the applied electrical energy was also demonstrated. The integrated bifurcation-based microfluidic platform is the first microsystem that enables biofilm growth with reduced variance, as well as continuous real-time threshold-activated feedback monitoring and treatment using low electric fields. The sensors detect biofilm growth by monitoring the change in impedance across the interdigitated electrodes. Using the measured impedance change and user inputs provided through a convenient and simple graphical interface, a custom-built MATLAB control module intelligently switches the system into and out of treatment mode. Using this self-governing microsystem, in situ biofilm treatment based on the principles of the bioelectric effect was demonstrated by exposing two of the channels of the integrated bifurcation device to low doses of antibiotics.

Re-conceptualiser notre expérience de l’environnement audio-visuel qui nous entoure : l’individuation, entre attention et mémoire

Notre mémoire prend en charge de re-conceptualiser notre nouvel environnement audio-visuel et l’expérience que nous en faisons. À l’ère du numérique et de la dissémination généralisée des images animées, nous circonscrivons une catégorie d’images que nous concevons comme la plus à même d’avoir un impact sur le développement humain. Nous les appelons des images-sons synchrono-photo-temporalisées. Plus spécifiquement, nous cherchons à mettre en lumière leur puissance d’affection et de contrôle en démontrant qu’elles ont une influence certaine sur le processus d’individuation, influence qui est grandement facilitée par l’isotopie structurelle qui existe entre le flux de conscience et leur flux d’écoulement. Par le biais des recherches de Bernard Stiegler, nous remarquons également l’important rôle que jouent l’attention et la mémoire dans le processus d’individuation. L’ensemble de notre réflexion nous fait réaliser à quel point le système d’éducation actuel québécois manque à sa tâche de formation citoyenne en ne dispensant pas un enseignement adéquat des images animées.

Code pattern analysis of object-oriented programming languages

Code patterns, including programming patterns and design patterns, are good references for programming language feature improvement and software re-engineering. However, to our knowledge, no existing research has attempted to detect code patterns based on code clone detection technology. In this study, we build upon the previous work and propose to detect and analyze code patterns from a collection of open source projects using NiPAT technology. Because design patterns are most closely associated with object-oriented languages, we choose Java and Python projects to conduct our study. The tool we use for detecting patterns is NiPAT, a pattern detecting tool originally developed for the TXL programming language based on the NiCad clone detector. We extend NiPAT for the Java and Python programming languages. Then, we try to identify all the patterns from the pattern report and classify them into several different categories. In the end of the study, we analyze all the patterns and compare the differences between Java and Python patterns.

Aerobic profile of climbers during maximal arm test

This study compared measurements of upper body aerobic fitness in elite (EC; n = 7) and intermediate rock climbers (IC; n = 7), and a control group (C; n = 7). Subjects underwent an upper limb incremental test on hand cycle ergometer, with increments of 23 W.min(-1), until exhaustion. Ventilation (VE) data were smoothed to 10 s averages and plotted against time for the visual determination of the first (VT1) and second (VT2) ventilatory thresholds. Peak power output was not different among groups [EC = 130.9 (+/- 11.8) W; IC = 122.1 (+/- 28.4) W; C = 115.4 (+/- 15.1) W], but time to exhaustion was significantly higher in EC than IC and C. VO(2PEAK) was significantly higher in EC [36.8 (+/- 5.7) mL.kg(-1).min(-1)] and IC [35.5 (+/- 5.2) mL.kg(-1).min(-1)] than C [28.8 (+/- 5.0) mL.kg(-1).min(-1)], but there was no difference between EC and IC. VT1 was significantly higher in EC than C [EC = 69.0 (+/- 9.4) W; IC = 62.4 (+/- 13.0) W; C = 52.1 (+/- 11.8) W], but no significant difference was observed in VT2 [EC = 103.5 (+/- 18.8) W; IC = 92.0 (+/- 22.0) W; C = 85.6 (+/- 19.7) W]. These results show that elite indoor rock climbers elicit higher aerobic fitness profile than control subjects when measured with an upper body test.

Transient process in ice creams evaluated by laser speckles

When a coherent light beam is scattered from a colloidal medium, in the observation plane, appears a random grainy image known as speckle pattern. The time evolution of this interference image carries information about the ensemble-averaged dynamics of the scatterer particles. The aim of this work was to evaluate the use of dynamic speckles as an alternative tool to monitoring frozen foams formulated with glucose and fructose syrups. Ice creams, after preparation and packing, were stored at 18 degrees C. Changes in properties of products were analyzed by speckle phenomena at three room temperatures (20 degrees C, 25 degrees C and 30 degrees C), minute by minute, during 50 min. Two moments were identified in which samples activity achieved significant levels. These instants were associated, respectively, to ice crystals melting and to air bubbles dissipation into the food matrix causing motion of diverse structures. As expected, ice crystals melting was first in formulations containing fructose syrup, but for same samples, air losses were delayed. Speckle methodology was satisfactory to observe temporal evolution of transient process, opening goods prospects to application, still incoming, in foodstuffs researches. (C) 2010 Elsevier Ltd.

Repertórios de ação coletiva e a efetividade das instituições participativas das comunicações : o caso do coletivo intervozes

Esta pesquisa investiga a relação entre os repertórios de ação coletiva adotados por organizações de movimentos sociais e a efetividade das instituições participativas (IPs) que tratam das políticas de comunicações no Brasil, ou seja, o Conselho de Comunicação Social do Congresso Nacional (CCS) e a 1ª Conferência Nacional de Comunicação (ConfeCom). A discussão gira em torno das ações implementadas pelo Coletivo Intervozes, organização da sociedade civil que atua nos movimentos sociais em prol do direito à comunicação e de sua democratização. Nesse contexto, dá-se ênfase às ações por um novo marco legal e regulatório das comunicações, consideradas como resultado dos problemas de efetividade observados no CCS e na ConfeCom. O trabalho está dividido em quatro capítulos. No primeiro, o destaque é para o Coletivo Intervozes, sua história, forma de organização, além de seus principais eixos de atuação e ações. No segundo, essencialmente teórico, enfatizam-se as definições conceituais que envolvem os movimentos sociais e a mudança institucional. O capítulo 3 é dedicado à análise dos problemas de efetividade nas IPs atinentes à área de comunicações e suas relações com os repertórios de ação coletiva. Como variáveis de análise, utiliza-se o acesso/representação da sociedade civil e as funções atribuídas às IPs. No último capítulo, analisa-se as características do movimento social que reivindica um novo marco legal e regulatório das comunicações e que surgiu como ação alternativa às IPs na defesa de mudanças institucionais para o setor. Como esta é uma pesquisa qualitativa, as análises foram feitas a partir de entrevistas semiestruturadas com membros do Coletivo Intervozes e especialistas da área; de acesso a documentos públicos produzidos pela organização e a dados bibliográficos, audiovisuais e sonoros referentes ao CCS e à ConfeCom.
