Distacco di retina e lavoro manuale: utilizzo delle schede di dimissione ospedaliera per uno studio di incidenza

Introduzione. La movimentazione manuale di carichi è stata recentemente proposta come un possibile determinante del distacco di retina. Al fine di confortare quest’ipotesi, sono stati analizzati i tassi di incidenza di distacco di retina regmatogeno (DRR) idiopatico, trattato chirurgicamente, tra i residenti in Toscana addetti ad attività lavorative manuali, non manuali e casalinghe. Metodi. Le schede di dimissione ospedaliera (SDO) della Toscana contengono anche informazioni codificate sulla categoria generica di impiego. Sono stati utilizzati i dati di tutti i pazienti residenti in Toscana con una SDO emessa da un qualsiasi ospedale italiano nel periodo 1997-2009, con diagnosi principale di DRR (ICD-9: 361,0-361,07 e 361,9) e con DRG 36 (“interventi sulla retina”). Dopo l’eliminazione dei soggetti che non soddisfacevano i criteri di eligibilità, è stato deciso di restringere la popolazione in studio ai soggetti di età 25-59 anni, successivamente classificati in addetti ad attività lavorative manuali, non manuali o casalinghe. Risultati. Sono stati identificati 1.946 casi. Tra gli uomini, gli addetti ad attività lavorative manuali hanno riportato un tasso di incidenza standardizzato per età 1,8 volte più alto rispetto agli addetti ad attività lavorative non manuali (17,4 [IC95%, 16,1–18,7] vs. 9,8 [IC95%, 8,8–10,8]). Tra le donne, i tassi di incidenza standardizzati per età erano 1,9 volte più alti negli addetti ad attività lavorative manuali (11,1 [IC95%, 9,8–12,3]) e 1,7 volte più alti nelle casalinghe (9,5 [IC95%, 8,3–10,8]) rispetto agli addetti ad attività lavorative non manuali (5,7 [IC95%, 4,8–6,6]). Conclusioni. Lo studio mette in evidenza come gli addetti ad attività lavorative manuali siano maggiormente affetti da DRR idiopatico rispetto agli addetti ad attività lavorative non manuali. Questi risultati supportano l’ipotesi che la movimentazione manuale di carichi, che difficilmente può ritrovarsi come compito di attività lavorative non manuali, possa avere un ruolo causale nella genesi della patologia.

Quality of child abuse information in emergency department injury surveillance data : linking hospital and child welfare data

Emergency departments (EDs) are often the first point of contact with an abused child. Despite legal mandate, the reporting of definite or suspected abusive injury to child safety authorities by ED clinicians varies due to a number of factors including training, access to child safety professionals, departmental culture and a fear of ‘getting it wrong’. This study examined the quality of documentation and coding of child abuse captured by ED based injury surveillance data and ED medical records in the state of Queensland and the concordance of these data with child welfare records. A retrospective medical record review was used to examine the clinical documentation of almost 1000 injured children included in the Queensland Injury Surveillance Unit database (QISU) from 10 hospitals in urban and rural centres. Independent experts re-coded the records based on their review of the notes. A data linkage methodology was then used to link these records with records in the state government’s child welfare database. Cases were sampled from three sub-groups according to the surveillance intent codes: Maltreatment by parent, Undetermined and Unintentional injury. Only 0.1% of cases coded as unintentional injury were recoded to maltreatment by parent, while 1.2% of cases coded as maltreatment by parent were reclassified as unintentional and 5% of cases where the intent was undetermined by the triage nurse were recoded as maltreatment by parent. Quality of documentation varied across type of hospital (tertiary referral centre, children’s, urban, regional and remote). Concordance of health data with child welfare data varied across patient subgroups. Outcomes from this research will guide initiatives to improve the quality of intentional child injury surveillance systems.

Os africanos livres na Casa de Correção: política e direito como disciplinarização

O presente trabalho analisa os africanos livres durante a construção da Casa de Correção da Corte. Para conhecer esse caminho, a investigação começa com a lei de 7 de novembro de 1831 e termina com a inauguração da primeira prisão com trabalho do país, em 1850. A dissertação tem como fio condutor o estudo da produção jurídica sobre os africanos livres e para isso, levam-se em consideração três eixos documentais: as leis brasileiras, os relatórios ministeriais e os despachos burocráticos relativos à administração da casa. O exame dessa material possibilita a operacionalização da noção de disciplinarização e como ela construiu a identidade dos africanos livres como trabalhadores. A disciplina como instrumento de formação de trabalhadores foi o meio de viabilizar a utilização dessa mão de obra. Esse estudo, ao problematizar aos africanos livres na condição de trabalhadores debate as formas de trabalho no Império do Brasil, colocando em pauta as experiências da escravidão e as expectativas do trabalho livre. E nessa análise, o sentido político das enunciações jurídicas foi o cerne para entendimentos desses agentes históricos. Dessa forma, eles foram instruídos e capacitados em diferentes ofícios, na qual recebiam salário e pagavam por sua subsistência. Nesse sentido, a dissertação se estrutura na relação da produção jurídica com a experimentação do trabalho livre.

Gestão de multi-projeto no processo de desenvolvimento de produto

No âmbito da unidade curricular Dissertação/Projeto/Estágio do 2º ano do Mestrado em Engenharia mecânica – Ramo Gestão Industrial do Instituto Superior de Engenharia do Porto, o presente trabalho de dissertação foi enquadrado num projeto de desenvolvimento de ferramentas de apoio à gestão de projetos. O projeto foi desenvolvido no Instituto de Engenharia Mecânica e Gestão Industrial (INEGI) na unidade de Desenvolvimento de Produto e Sistemas (DPS). A realização deste projeto teve como objetivo o desenvolvimento e adequação de ferramentas de apoio à gestão de multi-projeto no processo de desenvolvimento de produto na organização em estudo – o INEGI – DPS. A gestão de projetos tem hoje uma grande importância nos resultados das empresas essencialmente em virtude da necessidade de estas competirem num mundo em grande mudança com concorrentes ferozes, em que a capacidade de responder às mudanças a tempo e de uma forma integrada se torna cada vez mais importante. A atividade levada a cabo pela DPS impõe a necessidade de uma gestão de projetos mais eficaz e eficiente suportada numa gestão de informação centralizada. O presente projeto de investigação teve, numa primeira fase, uma adaptação à organização em estudo. De seguida, foi conduzida uma revisão da literatura com o objetivo de se obter a fundamentação teórica necessária ao desenvolvimento de ferramentas com base nas metodologias lean. Prosseguiu com o levantamento da situação inicial da organização e com a identificação dos problemas existentes na gestão de projetos. Incluiu também uma revisão e análise das ferramentas existentes na unidade em estudo. Este conhecimento permitiu delinear uma visão para guiar o desenvolvimento das ferramentas. Após a definição da visão foi, então, realizado o desenvolvimento das ferramentas de auxílio à gestão multi-projeto na organização. A concretização deste trabalho resultou no desenvolvimento de três ferramentas de auxílio à gestão multi-projeto na unidade. Estas ferramentas tornam o processo de gestão de projetos mais simples e fácil de assimilar, requerendo apenas alguns inputs por parte dos colaboradores. Estas ferramentas estão apoiadas nos pilares do lean, e deste modo estão vocacionadas para reduzir o desperdício, promover a melhoria contínua, aumentar o desempenho global dos vários atores nos projetos de modo a entregar mais valor e qualidade superior com menores custos. Acima de tudo, valorizar o trabalho dos colaboradores, tornando-os mais eficientes, eficazes, motivados e comprometidos com a organização.

Fonte de Iluminação LED – Avaliação dos Efeitos Fotobiológicos no Olho e Pele

Tendo por referência a diretiva 2006/95/CE, o trabalho desenvolvido no contexto da disciplina de Dissertação/Projeto/Estágio do Mestrado de Engenharia de Instrumentação e Metrologia, decorreu nas instalações do IEP (Instituto Electrotécnico Português) e teve como objetivo principal o desenvolvimento de um procedimento de avaliação dos efeitos fotobiológicos no olho e pele provocados por fontes de emissão contínua (LED), doravante designado método alternativo ao de referência. Os dois métodos, alternativo e de referência, utilizam respectivamente um foto-radiómetro multicanal e um espetro-radiómetro. O procedimento desenvolvido (método alternativo) de acordo com a norma EN/IEC62471) consiste na aquisição dos valores de irradiância com recurso a um foto-radiómetro e posterior determinação dos valores da radiância, com os quais se faz a avaliação dos efeitos fotobiológicos, para fontes de luz LED (Light Emitting Diode) ou GLS (General Lighting Service). A consulta detalhada da norma EN/IEC62471 e a pesquisa sobre os conceitos, definições, equipamentos e metodologias relacionadas com o tema em causa, constituiu o primeiro passo deste projecto. Com recurso aos dois equipamentos, uma fonte de luz LED (módulo de 12 lâmpadas LED) é avaliada em relação aos perigos (ou riscos) actínico UV e UV-A, ao perigo da luz azul e ainda o perigo térmico na retina e térmico na pele, permitindo fazer uma análise comparativa dos resultados. O método alternativo revelou-se bastante flexível e eficaz, proporcionando bons resultados em termos da irradiância e radiância dos referidos efeitos fotobiológicos. A comparação destes resultados com os valores limites de exposição mencionados na norma EN/IEC6247 permitiu afirmar que a fonte de luz LED avaliada não representa perigo fotobiológico para a saúde humana e classifica-se no grupo de risco “isento”. Uma vez cumpridos os objectivos, entendeu-se que seria uma mais-valia para o trabalho já realizado, estudar outro caso prático. Sendo assim, fez-se a avaliação da radiação de apenas um dos LED´s que constituíam a fonte usada nos ensaios anteriores, com o espetro-radiómetro (método de referência) e com uma distância de 200 mm entre a fonte e o medidor. Neste caso verificaram-se diferenças significativas nas quantidades obtidas quando comparadas com os valores normativos. Concluiu-se que o efeito fotobiológico da luz azul insere-se no grupo de “isento”, sem perigo para a saúde. Contudo, o efeito térmico da retina apresenta um aumento considerável da quantidade de radiância, embora dentro do grupo de risco “isento”. Esta classificação de grupos de risco. Face aos resultados obtidos, pode confirmar-se que as lâmpadas LED apresentam segurança fotobiológica, atendendo aos baixos valores de irradiância e radiância dos efeitos fotobiológicos estudados. Pode ainda afirmar-se que a utilização do foto-radiómetro em alternativa ao espetro-radiómetro se revela mais eficaz do ponto de vista de metodologia prática. Este trabalho demonstra a robustez desses dois equipamentos de avaliação dos efeitos fotobiológicos, e procura estabelecer uma linha de orientação para a prevenção dos efeitos adversos na pele e olhos de todos os seres humanos sujeitos à radiação ótica artificial. Quanto às incertezas de medições, em relação ao processo de medição com foto-radiómetro, a sua estimação não se realizou, devido a não rastreabilidade entre as medições indicadas pelo fabricante, no certificado de calibração e as medidas realizadas por outras entidades. Contudo, é propõe-se a sua realização em trabalhos futuros dentro desse âmbito. As incertezas dos resultados de medições com espetro-radiómetro foram parcialmente estimadas. Atendendo às potencialidades do sistema de medição, propõe-se como trabalho futuro, a aplicação da norma IEC62478, que faz parte da aplicação da norma EN/IEC62471 na avaliação do efeito da luz azul, com base na determinação da temperatura de cor correlacionada (CCT) de lâmpadas ou sistemas de lâmpadas incluindo luminárias. Os valores de irradiância e radiância adquiridos nos processos de avaliação, tanto com foto-radiómetro como espectro-radiómetro foram gravados em ficheiro Excel para um CD e anexados a este trabalho.

El centro comercial : una teoría tipológica : claves para el reconocimiento de una arquitectura ignorada

Existe en el panorama edificado un patrimonio construido que se reconoce como Centro Comercial. Un conjunto entendido, en sentido genérico, como familia arquitectónica que tiene características propias y específicas que la identifican. El objeto de la presente tesis doctoral consiste en argumentar que este conjunto constituye un nuevo tipo en el panorama de las tipologías arquitectónicas. Un tipo con entidad propia, que se conecta a una forma diferente de entender la idea de modelo. Un concepto que va más allá de la consideración tradicional del término. Modelo virtual. Este tipo, que surge de una estructura teórica que hemos denominado teoría tipológica, se constituye en una herramienta más para el estudio y el desarrollo proyectual de los espacios arquitectónicos, tanto del propio Centro Comercial como del conjunto de la disciplina arquitectónica, como referencia legítima. El presente trabajo de tesis se inicia con un bloque introductorio denominado Método. Definimos en él una metodología que hemos llamado emocional. Trata de la oportunidad de la tesis. Del porqué de un título que recoge la palabra ignorada. Del interés que suscita el asunto en el contexto del momento presente. Oportunidad e interés en base a una vida profesional dedicada al mundo del Centro Comercial y a la importancia del patrimonio elegido como objeto de estudio. También ha sido un aliciente detectar como las planificaciones del territorio y de los ámbitos de las relaciones colectivas no han sido capaces de integrar un resultado satisfactorio. Quizás por no considerar la complejidad de sus muchas facetas. En consecuencia, el texto busca la esencia del Centro Comercial como soporte para la crítica de su impacto en los nuevos escenarios de relación que la sociedad y el entorno físico imponen. Ámbitos donde los mecanismos históricos del asociacionismo tradicional han dado paso a otros, como el Centro Comercial, de exaltación del individualismo, pero demandados por una sociedad que se identifica con ellos. Espacios que, con Galbraith, existen por de la perversidad intrínseca del binomio consumo-producción que inducen la perplejidad. Ésta pasa a formar parte de la esencia del nuevo espacio comercial, como quedó de manifiesto en el Congreso de Minnesota de 1997, sobre el Centro Comercial. Una sociedad que ha girado hacia el logro material en términos de culto, ocasionando creciente valor significante del consumo. Razón última de la humanidad al decir de Rem Koolhaas. Culto que desemboca en la urgencia de alcanzar niveles de estatus y de identificación con el grupo. Dos parámetros que marcan la relación con el otro. Relación de comparación que excita la necesidad de posesión de objetos que llevaban a recrear en el consumidor la ilusión de ser especiales, de no pasar desapercibidos. El producto de consumo, el objeto, se eleva a la consideración de valor social. En el Centro Comercial se venden valores. Marketing de valores. El deseo del individuo, no la necesidad, queda involucrado en el proceso. La oportunidad y el interés de este estudio surgen además para aclarar el significado de un espacio que sirve al consumidor y a su entorno. Un significado que alcanza sentido, entre otros, por la aparición de un nuevo contexto tras la Segunda Guerra Mundial. Suburbanización, automóvil, nivel de vida, un nuevo papel de la mujer. La Era del Consumo. Una era que genera la paradoja de un individuo con autodeterminación y autosuficiencia crecientes, en un mundo cada vez más condicionado y controlado por dinámicas de ofertas mediatizadas e ilimitadas. La arquitectura en este contexto ha de juzgarse por su relación con un hombre contemporáneo que camina hacia una progresiva excepcionalidad. Cerramos la presentación justificando el término ignorada que aparece en el Título de la Tesis. Subrayamos la escasa existencia de estudios estructurados que relacionen Centro Comercial y arquitectura. Realidad que se constata partiendo del libro de Pevsner, Historia de las Tipologías Arquitectónicas, de 1976. Analizamos también la aceptación que el Centro Comercial, valorado en algunos ámbitos como arquitectura populista. Primer Capítulo, los antecedentes. Se propone un recorrido histórico por la arquitectura comercial de todos los tiempos. El Documento busca concretar las características de la arquitectura comercial a lo largo de la historia para determinar relaciones entre ella y el Centro Comercial. Estas correspondencias van a permitir contestar la pregunta retórica que nos hacemos al inicio del Capítulo: ¿Es la arquitectura del Centro Comercial una arquitectura subsidiaria, o tiene personalidad propia independiente de la del mundo comercial? Con Zevi40, queremos dejar constancia que la relación arquitectura-historia es imprescindible en la tarea proyectual. Un análisis novedoso solo es posible desde la búsqueda de unas raíces auténticas. Así mismo, con Guy de Maupassant, estamos convencidos que “La arquitectura, a través de los siglos, ha tenido el privilegio de dar un símbolo a cada una de las épocas, de resumir con un pequeñísimo número de monumentos típicos, el modo de pensar, de soñar de una raza y de una civilización”. Este recorrido se inicia interpretando la arquitectura comercial minoica. Llegaremos, paso a paso, hasta el siglo XX, los grandes itinerarios comerciales y el Centro Comercial. Se descubren una serie de invariantes que permiten comparar y extraer conclusiones. Resulta novedoso constatar que el Centro Comercial nace para dar respuesta al hombre contemporáneo en su afán consumista. También lo es la rápida implantación y evolución del Centro Comercial en un corto periodo de sesenta años frente al ritmo sosegado de otras soluciones comerciales. Novedad es ver como el comercio y sus arquitecturas nacen abiertos, bajo tenderetes y el Centro Comercial se presenta cerrado. Así mismo, las referencias sacras constituyen un elemento de novedad para la reflexión, en un contexto materialista. Y tantas otras. En Minos, la óptica comercial ofrece otra visión de su legendaria cultura. ¿Palacio o plataforma logística?, gestión centralizada del intercambio, ¿vida pública y vida privada? Así, hasta llegar al siglo XIX. Sus las galerías y sus pasajes acristalados concebidos en primera instancia como medida de recomposición urbana. Espacio entendido desde lo público-privado, desde lo interior-exterior, desde el dentro-afuera, desde lo cerrado-abierto. Con los nuevos mercados de abastos, representan una revolución en el ámbito de la funcionalidad, de la máquina, de la gestión moderna y de las relaciones del ciudadano con la ciudad apoyado en base al intercambio de bienes de consumo. El Centro Comercial es heredero de esta transformación. El Gran Almacén, por otra parte, es el reflejo de otra gran revolución. La que va ligada a la producción y comercialización en masa, las comunicaciones, el precio fijo y el aumento del nivel de vida. El Centro Comercial reinterpreta estas situaciones insertándolas en un nuevo modelo de gestión. En el siglo XX, maestro en técnicas de venta, aparece el hipermercado. El Híper, con su carga de pedagogía, se incorpora al esquema orgánico del Centro Comercial. La tienda en si misma constituye la pieza base de dicho puzle orgánico. Es en esta época cuando la tienda empieza su despegue autónomo como arquitectura, aportando su experiencia. Tras ello, llegamos a las grandes rutas comerciales, que proponemos como metáfora del shopping. Cerramos el capítulo concluyendo con Eugenio Ferrer que “si establecemos una relación entre el espacio y el capitalismo, entonces podemos inferir que los espacios del consumo de masas (ECM) son configuraciones nuevas respecto al pasado (...), pero el sistema que lo introduce no lo es del todo”. Segundo Capítulo. Búsqueda de claves que permitan el reconocimiento del Centro Comercial. Llegados a este punto y con la perspectiva del tiempo cabe preguntarnos, ¿qué entendemos pues por Centro Comercial? ¿Cómo lo percibimos? Abordamos ahora el problema de la percepción del Centro Comercial y su significado. Además de constituirse en símbolo, referencia siempre presente, la eficacia del Shopping es una de las principales causas de su poder de atracción. El Centro Comercial resulta de la síntesis de la revolución del consumo y de la revolución de la gestión. Espacio eficaz del entretenimiento como destino. El usuario resuelve su vida cotidiana dentro de un hábitat que considera propio y que se entiende como el lugar hiperbólico de la transacción comercial. Espacio de la abundancia para el disfrute. Una arquitectura involucrada en esta eficacia. Su sentido del lugar no es otro que el Shopping, que se desenvuelve de forma análoga en todas partes. El hogar del consumidor. Las nuevas catedrales. Las catedrales del consumo. Destino místico. Lugar de peregrinación para el consumidor fervoroso. Espacio sagrado que integra al usuario en la cultura dominante. Cultura del consumo. Templos, donde el tiempo ha perdido su sentido. Paraíso. Un espacio donde la altura, la luz natural, la dimensión general refuerzan el carácter sacro de un espacio para una nueva religión laica. Un espacio seguro, protegido que nos acerca a ideas como la de útero materno, con su carga de calidez y de significación erótica aplicado al encuentro compra-comprador y, ligado a ello, la literatura especializada habla del Centro Comercial como nave espacial hiperesterilizada o de agujero negro que absorbe la energía cultural. Más allá, la simulación, donde se percibe un simulacro de ciudad. Simulacro coherente con todo lo que el Shopping desencadena a su alrededor. El lugar de los sueños, de la fantasía. Aquí los productos se han metamorfoseado en fetiches, en significados. Televisión tridimensional, donde el usuario actúa guiado por una pulsión similar al zapping. Espacio lúdico de la fascinación por comprar o de imaginar que se compra. Espacio de simulaciones que llevan a la ensoñación. Un nuevo lugar que sustituye al espacio cotidiano, con el señuelo de la protección, en un contexto imaginariamente público. Espacio de la hiperrealidad donde no se distingue la realidad de la fantasía, donde tras episodios de confusión y desconcierto, se borran las fronteras con lo imaginario. Espacio mágico, escenario del gran espectáculo del consumo, controlado milimétricamente, al modo de la visita a un gran monumento, que ha de sobrevivir a los tiempos para dar testimonio de nuestro momento. Un icono, un símbolo que transmite un mensaje, que solo el consumidor es capaz de interpretar. Una agitada mezcla, sin precedentes, de percepciones que hablan de perplejidad y asombro ante el fenómeno del Centro Comercial, su espacio y las reacciones del hombre contemporáneo. ¿Cuáles serían las claves que nos permitirían reconocer la calidad esencial de un Centro Comercial, en esta concurrencia de perplejidades? Primero, la función de servicio. Un espacio donde ocurren muchas más cosas que lo obvio, que la compra. Un edificio que se involucra con el entorno de la mano de lo inesperado, la sorpresa y las expectativas. Esta vocación de servicio conecta Centro Comercial y naturaleza arquitectónica. Función que sugiere percepciones ligadas a la experiencia de compra. Organismo que vive y late al unísono con su visitante, colocándose al servicio de sus necesidades, de su afán de consumo, del que vive. Segundo, la comunidad servida. El Centro comercial sirve a una sociedad concreta. La sociedad consumista. Una nueva sociedad que se identifica con el edificio desarrollando un sentido de comunidad al nivel de sus deseos. Esta comunidad que se configura a su alrededor, constituye el activo más poderoso para el éxito de su realidad cotidiana y de su futuro. Tercero, un compromiso de carácter holístico. La economía de la experiencia aplicada al afán consumista de una sociedad identificada con su Centro, da lugar a una experiencia holística planificada. Diseño emocional. Colaboración para el éxito de un conjunto de establecimientos comerciales que participan en la aventura espacio-comercial del Centro Comercial. Ellos son los inductores primarios del consumo. Pero esta colaboración tiene su culminación en la amplificación del mensaje, como un inmenso altavoz, que proviene de la unidad configurada por todos ellos. El reflejo de esta amplificación de mensajes, desde la poderosa unidad constituida, es el aumento de la rentabilidad, fin último de la operación. Cuarto, la forma a través de una identificación de carácter gestáltico. Desde la lectura gestáltica que hacemos de la unidad holística, se advierte una poderosa capacidad de comunicación del sistema con su contexto. Centro y entorno se tornan entonces cómplices que complementan sus realidades. El Centro Comercial, arquitectura estructurada como sistema se percibe –ha de percibirse- como forma unitaria que procede de una mirada de raíz gestáltica que continuamente la recompone desde una óptica espacial y física, ligada a la experiencia individual. Esta unidad formal, más allá de la forma real, se constituye en esencia de de su arquitectura. Quinto, el Centro Comercial como sistema. Un sistema soportado por la Teoría General de Sistemas. La consideración del Centro Comercial como sistema es consecuencia de su estructura holística. El todo no se comporta como la suma de las partes y estas no lo hacen como lo harían en solitario. De aquí surge la necesidad de diálogo permanente entre la comercialización –proceso de incorporación de partes- y su traducción al mundo del diseño –proceso de articular arquitectónicamente las partes. Como sistema así configurado, el Centro Comercial se inserta en el paradigma contemporáneo, lo que genera realidades duales que no son excluyentes y reacciones de perplejidad e incertidumbre que el sistema corrige con su capacidad de autorregulación. Aparece también el espectador cuántico, el visitante, el consumidor, que interactúa con el sistema. Desde las herramientas que nos aporta la idea de sistema complejo, afrontamos el Mix Comercial -en definitiva la eficaz localización de las piezas en orden a sus relaciones y al organismo resultante- y su incidencia en la arquitectura que estamos concibiendo. Una arquitectura impredecible por lo mutable, que se erige en reto de la operación y del diseñador. Diseño que, de la mano del concepto de sistema se convierte en herramienta a mayor gloria de la operación global. El debate del estilismo no será más que el resultado del análisis en busca del éxito de esta operación. Sexto, una arquitectura de la negociación. Negociación como mecanismo proyectual y como resultado. La solución de proyecto nunca resulta evidente en el Centro Comercial como consecuencia de lo imprevisible del propio proceso de configuración. Su concreción solo puede ser fruto del compromiso de todos los agentes por conseguir el objetivo de la operación. Esto se consigue desde el equilibrio de intereses. Comerciales y de diseño. Un compromiso con la negociación y una negociación íntimamente ligada a la coordinación. Séptimo, el espacio y el tiempo. El debate espacio-tiempo condiciona y estructura la percepción del Centro Comercial. Introducimos conceptos como cronotopo –el instante y el lugar donde ocurre algo- y paradoja –incoherencia de la relación causa efecto- que sitúan el vínculo entre el tiempo y el espacio del Centro Comercial en un contexto de Shopping. En el discurrir paralelo del tiempo histórico –el tiempo de fuera- y del tiempo interior, el de dentro del Centro Comercial –tiempo presente o intemporalidad-, se produce el triunfo social del Centro Comercial que se traduce en haber sabido resolver en el espacio y en el tiempo las paradojas postmodernas del hombre contemporáneo. Octavo, de lo global. Globalidad que no es ajena a lo local. Una arquitectura que insertada en la dinámica de una economía de ámbito mundial, refleja las contradicciones que ella impone, fundamentalmente en los procesos de inclusión y exclusión, afectando de manera decisiva al debate de lo local, que el Centro Comercial debe incorporar como herramienta ineludible de reconocimiento. Terminamos el capítulo segundo manifestando como estas ocho claves, asumidas en su conjunto, confirman que el Centro Comercial puede aparecer como un todo conceptual cohesionado, pasando a formar parte de una familia arquitectónica coherente, cuya estructura funcional somos capaces de establecer. El Capítulo Tercero presenta con detalle la figura del arquitecto Víctor Gruen, creador reconocido del moderno Centro Comercial. Presentamos su trayectoria profesional observando como las diferentes claves analizadas en capítulos anteriores van apareciendo de manera natural a lo largo de ella "Victor Gruen may well have been the most influential architect of the twentieth century." Malcolm Gladwell. The Terrazo Jungle. Fifty Years Ago, The Mall Was Born. America Never Would Be The Same. 2004. In The New Yorker. Hombre complejo, conflictivo. Las paradojas a lo largo de su carrera fueron notables. Sin embargo siempre apareció como un hombre recto. Garret Eckbo, reconocido paisajista y colaborador de Gruen en el Centro Comercial peatonal del Centro urbano de Fresno, California, se asombraba de que alguien como Gruen hubiese sido capaz de combinar cortesía y humanidad en la carrera de ratas (sic) en la que se convirtió el universo de la comercialización americana y mantener la integridad542. Philip Johnson, en 1962, ponderando las muchas habilidades de Gruen manifestó que no estaba seguro si alguno de ellos, arquitectos artistas, hubiera sido capaz de hacer lo que Gruen hizo. A más, sobre Gruen, manifestó lo siguiente: "... El va más allá de la creación de un bello edificio. En jugar con la gente y sugerir lo que tienen que hacer, es un maestro. Y obtiene buenos resultados como hace la escultura. El suyo es un arte cívico, un sentido cívico.... Él es capaz de sentarse y poner cosas juntas. No es pomposo ni vano. Yo no me reuniría con él para hablar del diseño (de edificios). Víctor siente que cuando se habla de diseño se está ignorando todo el contexto... Su arquitectura es poderosamente limpia, no vuela la fantasía. Pero cuando te haces con su complejidad, ves que has descubierto algo más allá del diseño.... No puedes decir que haya alguien como él. La arquitectura tiene la suerte de tenerle como arquitecto..." Philip Johnson. Article in Fortune Review. 1962. El Documento de tesis cierra la visión de Gruen realizando un recorrido por los diferentes capítulos de su libro esencial, Shopping Towns Usa: The Planning of Shopping Centers. Solo su índice resulta un monumento al proceso de gestación del Centro Comercial. El libro, aquí simplemente mostrado en su estructura básica como un silencioso testigo, es la referencia canónica los Centros Comerciales contemporáneos, desde su aparición. . El Cuarto Capítulo del Documento de tesis es una recapitulación del trabajo anterior, en el que se sintetizan los conceptos de función y estilo relacionados con el Centro Comercial, se define en qué consiste cada uno de ellos y como, a partir de ahí, podemos afirmar que nos encontramos ante un tipo arquitectónico nuevo en el panorama de la disciplina arquitectónica. Terminamos el Capítulo integrando el Centro Comercial con un cuerpo teórico de referencias que se remiten a un tipo arquitectónico concreto y particular, acogiendo su singularidad como fenómeno arquitectónico autónomo. Como Conclusión de la tesis, resultado de todo lo anterior es decir, como consecuencia de la integración de un torrente de percepciones e intuiciones en un cuerpo teórico de referencias, deducidas de la existencia de unas claves que estructuran y penetran la esencia del singular modelo estudiado, haciéndolo detectable y seductor, resultan las características de un tipo arquitectónico con entidad propia que ordena, orienta y supedita la realidad y la existencia de esta nueva arquitectura. Una arquitectura nunca antes definida como tal, en el panorama tipológico de la disciplina. Teoría tipológica para una nueva arquitectura, que hemos ido proponiendo a lo largo del trabajo y que es coherente con los diferentes parámetros que se han analizado. Un conjunto edificado que, desde el estudio de sus claves esenciales y de sus invariantes perceptibles, aparece ahora más cercano, más familiar. Tanto que es posible destilar desde este conocimiento cercano e íntimo, una síntesis útil como referencia proyectual y como referencia para las grandes cuestiones que preocupan al discurrir del debate arquitectónico y sus ideas. El debate de la disciplina. El objeto de esta tesis, que consistía en establecer que el conjunto edificado que conocemos como Centro Comercial se constituye en un nuevo tipo en el panorama de las tipologías arquitectónicas, entendido el Centro Comercial en sentido genérico como familia arquitectónica con características propias y específicas que la hacen autónoma y reconocible, queda a nuestro juicio argumentado y justificado. ABSTRACT Within the frame of the built heritage there is a construction that is recognized as Shopping Center. An ensemble understood as an architectural family with its own specific recognizable characteristics. This thesis aims to explain that this building complex constitutes a new type in the panorama of architectural typology. This typology, with its singular identity, is connected to a way of understanding the idea of the model beyond an orthodox conception of the term understood as virtual model. This typology comes from a theoretical structure that we called typological theory, and it serves as yet another tool to reference the study and development design of the architectural spaces. In this first section, the Method, we emotionally explore the opportunities of this thesis. Why this typology has been ignored and the interest this work has in the present moment. An opportunity and an interest explained from an experience of a life dedicated to the world of Shopping Centers. The text then introduces the need for a rigorous knowledge of the Shopping Center’s essence in order to understand its impact in the frame of a new society and a new physical environment. A frame time where the historical mechanisms of association of civic community have given way to other gathering spaces like the Shopping Center, which encourages individualism, but is demanded by a society that relates to them. Spaces that, according to Galbraith, are a result of the intrinsic perversity of the unstoppable movement of the wheel of consumption-production. A society that has turned to worship of material achievement. Worship that provokes the appearance of an increasing value of consumption, according to Koolhaas, the only goal of humanity. Worship that ends in the need to reach certain status levels in the plane of a permanent comparison where the need of possession excites the consumer and gives them the illusion of being special. The product of consumption rises up to consideration of social values, entering a dynamic of marketing values, not only objects, but the desire of the individual remains. The study appears also to clarify the meaning of a space that serves the consumer and its context. A meaning that makes sense with the appearance of the suburbanization, the massive utilization of the car, the increase of living standards and the new role of women in the society after the Second World War, giving rise to the Age of Consumption. A world now determined and controlled by media and unlimited offers, where it’s necessary to place them in the context of the ordinary. An architecture that has to be judged precisely for its relation with this specific contemporary man. This section ends justifying the term ignored that appears in the Title of the Thesis, considering it in relation with the lack of studies structured about the Shopping Center and its architecture, drawing from Pevsner's work, A history of building types, 1976. Finally, the Shopping Center is analyzed with the most critical of thoughts, which considers it as populist architecture. The First Chapter, Precedents, proposes an historical tour of the commercial architecture throughout history. The Document looks to place on record the characteristics of the commercial architecture to set the connection between them and the Mall itself. These correspondences are going to allow us to answer the rhetorical question: is it the architecture of the Shopping Center a subsidiary architecture, or does it have its own personality independent from that of the commercial world? The reason of this historical search, citing Bruno Zevi, is that it is indispensable to establish the relationship between architecture and history, understating that an analysis is only possible when researching for their roots. Moreover, according to Guy de Maupassant, we are sure that architecture has had the privilege, across the centuries, of symbolizing as it were each age(…), through the harmony of lines and the charm of ornamentation all the grace and grandeur of an epoch. This historical reading, inseparable from a consistent design action, begins interpreting the commercial architecture of the Minoan to the 20th Century. Though this analysis of the big commercial itineraries and the study of the Shopping Center itself. A reading where we have found a series of constants that make it possible to draw conclusions from this comparison. The Mall appears to give response to the needs of a consumerist society. Comparing to the calm pace of the evolution of other commercial solutions, it is relevant its fast implantation and evolution in a short period of sixty years. Though via different solutions, the commercial spaces are considered taking into account the public-private relation, the interior-exterior, the inside-out, the closed-opened. Through that, the 19th century galleries and the food markets represent a revolution in functionality, in the machine, the modern management and the relations of the citizen within the city. All of this, the Mall inheritor feels. Likewise, the Department Store is the reflection of another great revolution. Production and commercialization en-mass, communications, the fixed price and increase of the living standard. The Mall reinterprets these situations inserting them in a new model of management. Already in the 20th century Mall and mass technologies of sale, the hypermarket is enthusiastically incorporated into the configuration of this organic scheme, constituting the base of one of the models, the French, that will be highly developed in the European continent. The shop itself constitutes, on the other hand, the key piece that completes the puzzle of the Mall and is in this epoch when it starts taking off as architecture, has an autonomous character. After all this, finally, we come to the big commercial routes, which we propose as metaphor of the shopping. Citing Eugenio Ferrer we can conclude that “If we establish a relation between the space and the capitalism, then we can infer that the spaces of the consumption of masses (ECM) are new configurations with regard to the past (...), but the system that introduces it it is not completely” Now we arrive at this point and with the perspective of time it is necessary to ask us, what do we understand about the Shopping Center? How do we perceive it? The second Chapter approaches the problem of the perception of the Mall and from this it is possible to detect and to identify key drivers that orientate the architectural comprehension of the space. The efficiency of the Shopping Center is its main power of attraction. A world that has ensued from the synthesis of the revolution of consumption and management. An effective cavern-like place of entertainment where the user, the consumer, the postmodern man solves his daily life inside a considered habitat. The hyperbolic place of commercial transaction. An abundance of space, that makes us perceive it as destination of entertainment. An architecture has evolved this efficiency, where the sense of place is at one with the sense of the Shopping. The home of the consumer. The new cathedrals. The cathedral of consumption. The place of peregrination for the fervent consumer. A sacred space that integrates the user in the dominant culture. A temple, where time itself has stopped existing. In this paroxysm, an expression of the Garden of Eden or Paradise itself. A space where the height, the natural daylight and the spatial dimension reinforce the sacred character of a new lay religion. Another common perception is that of a protected area, which leads to metaphors and considerations that suggest the idea of maternal womb, with its weight of erotic meaning, referring to the encounter of the shopper making a purchase. The literature also tells us about its perception as a sterile space capsule, a black hole that absorbs all cultural energy. Likewise, a world simulation where a mock city is perceived at first instance. Consistent with all that shopping triggers inside. A city, a space conceived as a place of dreams, fantasy, where the products have been metamorphosed into fetishes. Entertaining a television, three-dimensional television, where the user acts guided by a drive similar to zapping. A play area where the latest fascination is in the act of buying. Space simulations that unite and transcend creating atmospheres that lead to reverie. A new space replacing the daily space with the lure of safe space in a public context. A hyper-reality space with reality and fantasy, where borders are erased with imaginary episodes of confusion and bewilderment, without distinction. The charm and fascination of a space that reads like magic. The magic of a space which is defined as stage extravaganza, the large theatre, the consumer surveys in the fine control mode in which you visit a national monument. The shopping center has to survive the times to be a testimony of our time. An icon, a symbol that conveys a message, the message reads ‘consumer’. In short, a Shopping Center is a mix of unprecedented insights that speak of a widespread phenomenon of bewilderment. Its space and the reactions of contemporary man unfold in it like a fish in water. What are the key aspects which allow us to recognize the essential quality of a shopping center in this concurrence of perplexities? First, we want to record a service function of space much deeper than the immediately obvious, i.e. a purchase occurs. A building that appears to be involved with the environment and its people from the hand of the unexpected circumstances; surprise and attention. And that, in turn, also involves the visitor beyond the purchase. This dedication to service closely links the mall with its architectural nature. It is not the function of a lifeless machine. It is a feature that suggests unsuspected perceptions linked to the purchase, which speaks of an organism that lives and breathes in unison with the visitor. Second, in addition to the vocation of service-oriented desire for consumption, the Mall environment serves a particular society - The consumer society. A new society which relates to building a sense of community developed to the level of their desires. This community also constitutes the most powerful asset to the success of the daily life of the Shopping Center. Third, we emphasize that the so called economy of the experience is combined with the consumer zeal of a company that is identified by the Shopping Center. It connects to form a holistic and planned experience. This experience takes shape in the entity that ensues from the premeditated association and synergy, in the sense of a collaboration for success. A set of concrete commercial and independent establishments, take part in the spatial and commercial adventure that is the Mall and they are the instigators of the consumption. This holistic behavior finds culmination in the amplification of a claim that becomes unitary, like an immense force that leads to an increased profitability to all the levels. Consummation is a reference of one human being overturned in an architecture assimilated into a legitimate, emotional design with stability. A holistic quality is born of the essence of the building - and by virtue of the Conditions of Alexander, Christopher Alexander, determines the system condition of the Shopping Center. Fourth, we propose to establish what character the Mall will form when joined with the concept of its typology. This is going to allow the architectural work to be formed. As a result of the holistic structure that we see, the Mall is perceived as a system whose parts have their own function, justifying their existence in the ecosystem. Across a gestalt there is a powerful capacity of communication between the system and its context. We visualize on the one that stands out our building, turning both, Center and environment, in accomplices of a few special relations who complement each other in his realities. This relationship within a complex and diverse environment gives the Mall a range of unique spatial perceptions, the result of disparate experiences, which because of its root origin of gestalt, are integrated into a unified and coordinated manner fully intelligible and organized. This is the final formal essence of the Shopping Center. We can conclude here that the Mall as architecture is a structured system and should be perceived as a unit both from a physical and spatial perspective as this is the essence of its architecture. Fifth, the Mall as a system. A system which is being supported by a broad theoretical corpus, the General Systems Theory, which offers sufficient methodology to descend into consideration and give an enlightened conclusion on the overall understanding of the Mall. Consideration of the Mall as a system is a result of its holistic structure. The whole does not behave like any of the parties and they do not behave the way they used to before belonging to the whole, because they inhibit many of their qualities to their advantage. It arises the need for an ongoing dialogue between marketing processes and its translation into the physical world, the design. The system generates multiple perceptions to be integrated into a body which is to be understood as unitary. As a system, the Mall is inserted into the contemporary paradigm, creating dual realities that are not exclusive and are reactions of uncertainty that the system be properly designed at all levels, faced with their ability to self-regulate. Likewise, considering the visitor, the customer, like the quantum spectator who interacts with the system permanently. Moreover, a complex system confronts us with the Commercial mix, the effective location of parts in order to relate to the body and its importance in the architecture we are conceiving. Unpredictable architecture, which stands as the challenge of the operation and the designer. Design that becomes the tool of the system to create success for the overall operation. The discussion of the styling is merely the result of analysis that also seeks the success of the system, i.e. the styling should send the right message for the environment to ensure its survival. Sixth, the idea of negotiation as an architecture project, a mechanism inherent to the status of the proposed system. The project solution is never evident at the Shopping Center because of the unpredictability of the process itself. It can only be the fruit of the commitment of all stakeholders to achieve the objective of the operation. This is achieved from the balance of interests, of commercial and design. A commitment to negotiation and a negotiation linked to coordination. The pursuit of stability is key, as instability is always present and constantly requires strategies to build the object you are configuring. Seventh, proposes space-time itself as a circumstance that determines and structures the perception of the Mall in a singular way. We introduce concepts as chronotope and paradox to help us place the relationship between time and space within the Mall in the context of shopping. A consequence of the parallel flow of historical time - the time outside - and the time inside the Mall, the big shopping center formula is precisely that of having the feeling of timelessness in the space. The social triumph of the mall is the ability to resolve in space and in time all postmodern paradoxes and, beyond that, of contemporary man, condensing into a small space and time an enormous amount of cultural symbols, often contradictory, but they attract the practice of consumerism. Eighth, global level. Globalization which doesn’t ignore the local level. Architecture that is inserted into the dynamics of a global economy, reflects the contradictions that it imposes, mainly in the processes of inclusion and exclusion. Inclusion and exclusion affect the debate of the local level, which the Mall must incorporate as an unavoidable tool of recognition. The eight fundamental principles, when applied as a whole, confirm that the built heritage, which corresponds to the general Mall idea, can be presented as a cohesive conceptual whole. This becomes part of a coherent architectural family, whose functional structures are able to be established. The Third chapter presents in a detailed way the figure of the architect Victor Gruen, recognized as the creator of the modern Mall. Studying his professional experience, it is shown how the different keys analyzed in previous chapters are appearing in a natural way. "Victor Gruen may well have been the most influential architect of the twentieth century." Malcolm Gladwell. The Terrazo Jungle. Fifty Years Ago, The Mall Was Born. America Never Would Be The Same. 2004. In The New Yorker. He was a complex, troubled man and the paradoxes along his career were notable. Nevertheless, always he appeared as a straight man. Garret Eckbo, the recognized landscape painter and collaborator of Gruen was astonished how Gruen had been capable of combining comity and humanity in this career of rates, into that the American commercialization turned, Johnson, in 1962, weighting many Gruen's skills demonstrated that he was not sure if anyone of them, architects artists, had been capable of doing what Gruen did. He goes beyond just the creation of a beautiful building. In playing on people and suggesting what they ought to do, he is a master. (…) his architecture is clean - hardly architecture, no flights of fancy. But when you get hold of its complexity, you've got something beyond the design... You can't say there's someone like him. Architecture is lucky to have him as an architect." Philip Johnson. Article in Fortune Review. 1962. The Document of the thesis closes with Gruen's vision of realizing a tour through the different chapters of his essential book, Shopping towns USA: The Planning of Shopping Centers. It’s mere index turns out to be a monument to the process of the gestation of the Mall. The book, simply acted in its basic structure as a silent witness, as the canonical reference for the contemporary Malls. The Fourth Chapter of the Document of the thesis is a recapitulation of the previous work, which synthesizes the concepts of function and style related to the Shopping Center, and clearly defines how they are defined so we can conclude that we have found an architectural new type in the panorama of the architectural discipline. Therefore, the Conclusion of the thesis integrates this development in a theoretical body of references that relate to an architectural specific and particular type, which receives the singularity of the Shopping Center as an architectural independent phenomenon as it has tried to demonstrate from the beginning of the work. To conclude, as a result of the integrative process and the development of the theoretical body of references, the essential characteristics of the order and concept of the architectural typology form the existence of a new architecture; architecture never before defined as such, in the theoretical typology of the discipline. A theoretical typology for a new architecture is proposed throughout the discussed research and forms a conclusion of the different parameters that have been analysed. As a building complex, from the study of the essential characteristics and of the perceptible constants, the typology is more clearly defined and thus, becomes a useful tool and precedent for the consideration of the discipline. The thesis then justifies how the building complex known as Shopping Center constitutes a new type of architectural typology.

Decompression illness and its regulation in contemporary UK tunnelling : an engineering perspective:an engineering perspective

This thesis records the findings of a retrospective study of decompression illness (DCI) in the UK compressed air tunnelling industry since the mid-1980s. The thesis describes how the study arose, its scope and objectives, along with an overview of tunnelling and shaft-sinking. The development of compressed air working techniques is reviewed along with a description of decompression practice and DCI, and an outline of relevant legislation and guidance. The acquisition and manipulation of data to form a number of databases and spreadsheets on which the analysis was performed is discussed. That analysis examined measures of DCI incidence and quantified that incidence using these measures. Also considered is the variation in tolerance and susceptibility to DCI in the workforce, and the phenomenon of acclimatisation. An examination of the extent to which men worked on multiple contracts and the variation in their susceptibility to DCI on these contracts is included. Options are then considered for reducing the incidence of DCI. The first retained air-only decompression through the application of restrictions on exposure. The second related to the use of oxygen decompression. Finally the adequacy of the existing Regulations and Guidance is considered and recommendations made for possible changes to them, arising from the study. The main conclusions are that a number of measures of DCI incidence were identified, some more appropriate than others and that the incidence of DCI when so measured was high, disproportionately so in shift workers. No reasonably practicable restrictions on exposure were identified which would have allowed the retention of air-only decompression. Oxygen decompression looked promising but had yet to be used sufficiently extensively to generate enough data for analysis. Recommendations included one that an alternative technique for monitoring the effectiveness of decompression should be developed. The thesis ends with recommendations for further research.

Development of an electric heat pump for domestic use

This thesis records the design and development of an electrically driven, air to water, vapour compression heat pump of nominally 6kW heat output, for residential space heating. The study was carried out on behalf of GEC Research Ltd through the Interdisciplinary Higher Degrees Scheme at Aston University. A computer based mathematical model of the vapour compression cycle was produced as a design aid, to enable the effects of component design changes or variations in operating conditions to be predicted. This model is supported by performance testing of the major components, which revealed that improvements in the compressor isentropic efficiency offer the greatest potential for further increases in cycle COPh. The evaporator was designed from first principles, and is based on wire-wound heat transfer tubing. Two evaporators, of air side area 10.27 and 16.24m2, were tested in a temperature and humidity controlled environment, demonstrating that the benefits of the large coil are greater heat pump heat output and lower noise levels. A systematic study of frost growth rates suggested that this problem is most severe at the conditions of saturated air at 0oC combined with low condenser water temperature. A dynamic simulation model was developed to predict the in-service performance of the heat pump. This study confirmed the importance of an adequate radiator area for heat pump installations. A prototype heat pump was designed and manufactured, consisting of a hermetic reciprocating compressor, a coaxial tube condenser and a helically coiled evaporator, using Refrigerant 22. The prototype was field tested in a domestic environment for one and a half years. The installation included a comprehensive monitoring system. Initial problems were encountered with defrosting and compressor noise, both of which were solved. The unit then operated throughout the 1985/86 heating season without further attention, producing a COPh of 2.34.

Choreographing research : supervising the dancing thesis

The dancing doctorate is an interrogative endeavour which can but nurture the art form and forge a beneficial dynamism between those who seek and those who assess the emerging knowledges of dance’. (Vincs, 2009) From 2006-2008 three dance academics from Perth, Brisbane and Melbourne undertook a research project entitled Dancing between Diversity and Consistency: Refining Assessment in Postgraduate Degrees in Dance, funded by the ALTC Priority Projects Program. Although assessment rather than supervision was the primary focus of this research, interviews with 40 examiner/supervisors, 7 research deans and 32 candidates across Australia and across the creative arts, primarily in dance, provide an insight into what might be considered best practice in preparing students for higher research degrees, and the challenges that embodied and experiential knowledges present for supervision. The study also gained the industry perspectives of dance professionals in a series of national forums in 5 cities, based around the value of higher degrees in dance. The qualitative data gathered from these two primary sources was coded and analysed using the NVivo system. Further perspectives were drawn from international consultant and dance researcher Susan Melrose, as well as recent publications in the field. Dance is a young addition to academia and consequently there tends to be a close liaison between the academy and the industry, with a relational fluidity that is both beneficial and problematic. This partially explains why dance research higher degrees are predominantly practice-led (or multi-modal, referring to those theses where practice comprises the substantial examinable component). As a physical, embodied art form, dance engages with the contested territory of legitimising alternative forms of knowledge that do not sit comfortably with accepted norms of research. In supporting research students engaged with dance practice, supervisors traverse the tricky terrain of balancing university academic requirements with studies that are emergent, not only in the practice and attendant theory but in their methodologies and open-ended outcomes; and in an art form in which originality and new knowledge also arises from collaborative creative processes. Formal supervisor accreditation through training is now mandatory in most Australian universities, but it tends to be generic and not address supervisory specificity. This paper offers the kind of alternative proposed by Edwards (2002) that improving postgraduate supervision will be effective if supervisors are empowered to generate their own standards and share best practice; in this case, in ways appropriate to the needs of their discipline and alternative modes of thesis presentation. In order to frame the qualities and processes conducive to this goal, this paper will draw on both the experiences of interviewees and on philosophical premises which underpin the research findings of our study. These include the ongoing challenge of dissolving the binary oppositions of theory and practice, especially in creative arts practice where theory resides in and emerges from the doing as much as in articulating reflection about the doing through what Melrose (2003) terms ‘mixed mode disciplinary practices’. In guiding practitioners through research higher degrees, how do supervisors deal with not only different forms of knowledge but indeed differing modes of knowledge? How can they navigate tensions that occur between the ‘incompatible competencies’ (Candlin, 2000) of the ‘spectating’ academic experts with their ‘irrepressible drive ... to inscribe, interpret, and hence to practise temporal closure’, and practitioner experts who create emergent works of ‘residual unfinishedness’ (Melrose 2006) which are not only embodied but ephemeral, as in the case of live performance?

A news story as big as a doctoral thesis? : deploying journalistic methodology in academic research

The purpose of this paper is to identify and recommend the emergence of an academic research methodology for Journalism the academic discipline, through reviewing various journalistic methods of research – those making up a key element in such methodology. Its focus is on journalistic styles of work employed in academic contexts especially research on mass media issues. It proposes that channelling such activity into disciplined academic forms will enhance both: allowing the former to provide more durable and deeper outcomes, injecting additional energy and intensity of purpose into the latter. It will briefly consider characteristics of research methodologies and methods, generally; characteristics of the Journalism discipline, and its relationship with mass media industries and professions. The model of journalism used here is the Western liberal stream. A proposition is made, that teaching and research in universities focused on professional preparation of journalists, has developed so that it is a mature academic discipline. Its adherents are for the most part academics with background in journalistic practice, and so able to deploy intellectual skills of journalists, while also accredited with Higher Degrees principally in humanities. Research produced in this discipline area stands to show two characteristics: (a) it employs practices used generally in academic research, e.g. qualitative research methods such as ethnographic studies or participant observation, or review of documents including archived media products, and (b) within such contexts it may use more specifically journalistic techniques, e.g. interviewing styles, reflection on practice of journalism, and in creative practice research, journalistic forms of writing – highlighting journalistic / practitioner capabilities of the author. So the Journalism discipline, as a discipline closely allied to a working profession, is described as one where individual professional skills and background preparation for media work will be applicable to academic research. In this connection the core modus operandi will be the directly research-related practices of: insistent establishment of facts, adept crafting of reportage, and economising well with time. Prospective fields for continuing research are described:- work in new media; closer investigation of relations among media producers and audiences; journalism as creative practice, and general publishing by journalists, e.g. writing histories.

Legislative and security requirements of audit material for evidentiary purpose

This research used the Queensland Police Service, Australia, as a major case study. Information on principles, techniques and processes used, and the reason for the recording, storing and release of audit information for evidentiary purposes is reported. It is shown that Law Enforcement Agencies have a two-fold interest in, and legal obligation pertaining to, audit trails. The first interest relates to the situation where audit trails are actually used by criminals in the commission of crime and the second to where audit trails are generated by the information systems used by the police themselves in support of the recording and investigation of crime. Eleven court cases involving Queensland Police Service audit trails used in evidence in Queensland courts were selected for further analysis. It is shown that, of the cases studied, none of the evidence presented was rejected or seriously challenged from a technical perspective. These results were further analysed and related to normal requirements for trusted maintenance of audit trail information in sensitive environments with discussion on the ability and/or willingness of courts to fully challenge, assess or value audit evidence presented. Managerial and technical frameworks for firstly what is considered as an environment where a computer system may be considered to be operating “properly” and, secondly, what aspects of education, training, qualifications, expertise and the like may be considered as appropriate for persons responsible within that environment, are both proposed. Analysis was undertaken to determine if audit and control of information in a high security environment, such as law enforcement, could be judged as having improved, or not, in the transition from manual to electronic processes. Information collection, control of processing and audit in manual processes used by the Queensland Police Service, Australia, in the period 1940 to 1980 was assessed against current electronic systems essentially introduced to policing in the decades of the 1980s and 1990s. Results show that electronic systems do provide for faster communications with centrally controlled and updated information readily available for use by large numbers of users who are connected across significant geographical locations. However, it is clearly evident that the price paid for this is a lack of ability and/or reluctance to provide improved audit and control processes. To compare the information systems audit and control arrangements of the Queensland Police Service with other government departments or agencies, an Australia wide survey was conducted. Results of the survey were contrasted with the particular results of a survey, conducted by the Australian Commonwealth Privacy Commission four years previous, to this survey which showed that security in relation to the recording of activity against access to information held on Australian government computer systems has been poor and a cause for concern. However, within this four year period there is evidence to suggest that government organisations are increasingly more inclined to generate audit trails. An attack on the overall security of audit trails in computer operating systems was initiated to further investigate findings reported in relation to the government systems survey. The survey showed that information systems audit trails in Microsoft Corporation's “Windows” operating system environments are relied on quite heavily. An audit of the security for audit trails generated, stored and managed in the Microsoft “Windows 2000” operating system environment was undertaken and compared and contrasted with similar such audit trail schemes in the “UNIX” and “Linux” operating systems. Strength of passwords and exploitation of any security problems in access control were targeted using software tools that are freely available in the public domain. Results showed that such security for the “Windows 2000” system is seriously flawed and the integrity of audit trails stored within these environments cannot be relied upon. An attempt to produce a framework and set of guidelines for use by expert witnesses in the information technology (IT) profession is proposed. This is achieved by examining the current rules and guidelines related to the provision of expert evidence in a court environment, by analysing the rationale for the separation of distinct disciplines and corresponding bodies of knowledge used by the Medical Profession and Forensic Science and then by analysing the bodies of knowledge within the discipline of IT itself. It is demonstrated that the accepted processes and procedures relevant to expert witnessing in a court environment are transferable to the IT sector. However, unlike some discipline areas, this analysis has clearly identified two distinct aspects of the matter which appear particularly relevant to IT. These two areas are; expertise gained through the application of IT to information needs in a particular public or private enterprise; and expertise gained through accepted and verifiable education, training and experience in fundamental IT products and system.

A secure framework and related protocols for ubiquitous access to electronic health records using Java sim cards

Ubiquitous access to patient medical records is an important aspect of caring for patient safety. Unavailability of sufficient medical information at the point-ofcare could possibly lead to a fatality. The U.S. Institute of Medicine has reported that between 44,000 and 98,000 people die each year due to medical errors, such as incorrect medication dosages, due to poor legibility in manual records, or delays in consolidating needed information to discern the proper intervention. In this research we propose employing emergent technologies such as Java SIM Cards (JSC), Smart Phones (SP), Next Generation Networks (NGN), Near Field Communications (NFC), Public Key Infrastructure (PKI), and Biometric Identification to develop a secure framework and related protocols for ubiquitous access to Electronic Health Records (EHR). A partial EHR contained within a JSC can be used at the point-of-care in order to help quick diagnosis of a patient’s problems. The full EHR can be accessed from an Electronic Health Records Centre (EHRC) when time and network availability permit. Moreover, this framework and related protocols enable patients to give their explicit consent to a doctor to access their personal medical data, by using their Smart Phone, when the doctor needs to see or update the patient’s medical information during an examination. Also our proposed solution would give the power to patients to modify the Access Control List (ACL) related to their EHRs and view their EHRs through their Smart Phone. Currently, very limited research has been done on using JSCs and similar technologies as a portable repository of EHRs or on the specific security issues that are likely to arise when JSCs are used with ubiquitous access to EHRs. Previous research is concerned with using Medicare cards, a kind of Smart Card, as a repository of medical information at the patient point-of-care. However, this imposes some limitations on the patient’s emergency medical care, including the inability to detect the patient’s location, to call and send information to an emergency room automatically, and to interact with the patient in order to get consent. The aim of our framework and related protocols is to overcome these limitations by taking advantage of the SIM card and the technologies mentioned above. Briefly, our framework and related protocols will offer the full benefits of accessing an up-to-date, precise, and comprehensive medical history of a patient, whilst its mobility will provide ubiquitous access to medical and patient information everywhere it is needed. The objective of our framework and related protocols is to automate interactions between patients, healthcare providers and insurance organisations, increase patient safety, improve quality of care, and reduce the costs.
