A partir de um estudo quanti-qualitativo sobre a fotografia na mídia impressa - e também dos aportes em torno dos processos de sentido, das teorias do jornalismo e dos estudos audiovisuais -, a presente pesquisa pretende identificar os “elementos definidores” da natureza e das lógicas do uso da fotografia em Zero Hora, estruturando-se em torno da “crítica” da imagem realizada no box Foto comentada. A partir deste micro-espaço de tensionamento entre foto, edição fotográfica, leitor e jornal, pretende-se perceber para quais direções, no âmbito do sistema fotojornalístico, estas discussões apontam. Entre os movimentos metodológicos realizados, estão as incursões nos campos da recepção e da produção (por meio de entrevistas, observação participante e observação do box Foto comentada), e também a análise de 172 fotografias publicadas em Zero Hora durante o ano de 2005. Como principais aportes teóricos, podemos citar os autores Jorge Pedro Sousa, Susan Sontag, Donis A. Dondis, Nélson Traquina, Mauro Wolf, Roland Barthes, Vilém Flusser, Pepe Baeza, Henri Bergson, Suzana Kilpp e José Luiz Braga, entre outros. / The present essay intends to discuss the photography edition of the Zero Hora daily newspaper, approaching the production, the reception and the photojournalistic product as the three instances that allow us to understand this process. Starting from a quanti-qualitative study on the photography in the media printed - and also of the contributions around the sense processes, the journalism theories and the audiovisual studies -, the present research intends to identify the “definer elements” of the nature and logics of the use of the photography in Zero Hora, being structured around the “critic” of the image accomplished in the box Foto comentada. Starting from this tensive space among photography, photographic edition, reader and newspaper, intends to notice for which directions, in the extent of the photojournalistic system, these discussions appear. Among the accomplished methodological movements, are the incursions in the reception and production fields (through interviews, participant observation and observation of the box Foto comentada), and also the analysis of 172 photographs published in Zero Hora during the year of 2005. As main theoretical contributions, we can mention authors Jorge Pedro Sousa, Susan Sontag, Donis A. Dondis, Nélson Traquina, Mauro Wolf, Roland Barthes, Vilém Flusser, Pepe Baeza, Henri Bergson, Suzana Kilpp and José Luiz Braga, among others.

Manter-se informado, parece somar às pessoas certo status social, um valor na sociedade: o de “estar por dentro das notícias”. Os meios de comunicação, especificamente os jornais de circulação diária, passam, assim, a assumir a posição de mercadoria de consumo. Para melhorar a qualidade da mídia e assegurar sua responsabilidade social, surgem os conselhos de imprensa, que buscam a qualificação ao darem voz ao seu público. Nesse contexto, a presente pesquisa consistiu em um estudo junto ao Conselho do Leitor do jornal Zero Hora, principal jornal em termos de circulação do Estado do Rio Grande do Sul – Brasil, a fim de observar, descrever e analisar a dinâmica de funcionamento desse Conselho e se ele interfere ou não no processo de elaboração das edições do jornal. O estudo / In the present historical moment we are living, the search for knowledge and information about what is happening in our neighborhood, city, country or even ever part of the world, seems to be running along with our basic needs. To be informed, seems to add some social status to people, a value for being “inside the news”. The media, specially the daily newspapers, now start to assume the position of commodity. To improve the media quality and keep its social responsibility, Press Councils appeared, opening space to its audience to raise quality. From this point on, this research consists in a study in the Reader’s Council of the Zero Hora newspaper, the most important newspaper in the State of Rio Grande do Sul – Brazil, to describe and to analyze the dynamics operations of this Council, observing if it interferes or not on the elaboration process of the newspaper’s editions. Looking through this theme, the need of using many evidence sources appeared (participating/collaborative observation, semi-structure

After Brazil?s redemocratization, that concurs with the explosion of violent criminality in the country, isolated cases that used to homogenize media?s attention get out of the press focus and are replaced by contextualized stories on public security and security politics. To analise how and why these transformations have occurred on Zero Hora?s covering and what are its implications in the journalists professional context and in the routine of the editorial office, interviews have been made with journalists that act or have acted in ZH Police section. The answers, that do not intend to be definitive, have been reached analyzing the speech of those professionals, enlightened by Bourdieu?s teorical framework. Beyond the answers, elements that suggest a new stage of the journalistic covering have been identified in the agenda of repressive politics to fight violent criminality nowadays. / Esta disserta??o analisa a profunda transforma??o ocorrida na cobertura jornal?stica da criminalidade violenta a partir de meados da d?cada de 80, quando os principais jornais do Brasil come?am a ampliar suas abordagens, a diversificar fontes e a qualificar mat?rias. Ap?s a redemocratiza??o do Brasil, que coincide com a explos?o da criminalidade no pa?s, saem de foco casos isolados, que hegemonizavam a aten??o da imprensa, e ganham espa?o as reportagens contextualizadas sobre seguran?a p?blica e pol?tica de seguran?a. Para analisar como e por que as transforma??es na cobertura ocorreram em Zero Hora e quais as implica??es, no contexto profissional dos jornalistas e na rotina da Reda??o, da mudan?a na forma como a viol?ncia passou a ser tratada, realizou-se entrevistas com jornalistas que atuam ou atuaram na editoria de Pol?cia de ZH. As respostas, que n?o se pretendem definitivas, foram encontradas atrav?s da an?lise dos discursos dos profissionais,?luz do arcabou?o te?rico proposto por Bourdieu. Al?m das respostas, identificou-se elementos que sugerem uma nova etapa da cobertura jornal?stica no agendamento de pol?ticas repressivas de combate a criminalidade violenta nos dias atuais.

Neste trabalho é apresentado um estudo do ponto ZTC (Zero Temperature Coefficient) em dispositivos SOI MOSFETs, funcionando em modo parcialmente (PD-SOI) e totalmente (FD-SOI) depletados. O estudo é realizado a partir de um modelo analítico simples, proposto para determinação da tensão de polarização da porta do transistor no ponto ZTC (VZTC), através dos modelos de primeira ordem das características da corrente de dreno (IDS) em função da tensão aplicada a porta (VGF) do transistor, considerando as regiões de operação linear e de saturação. Para a validação do modelo, os resultados obtidos são confrontados com dados experimentais, e foi obtido um bom ajuste dos valores, apesar das simplificações adotadas para o modelo proposto. Foi realizada uma análise para estudar o impacto no valor de VZTC com a variação no valor de parâmetros de referência, como a concentração de portadores (Naf) e a espessura do óxido de porta (toxf). O erro máximo observado em VZTC, impondo a variação nos parâmetros Naf e toxf, para os dispositivos PD é de 3,1% e 4,6% na região linear, respectivamente; e 3,5% e 7,2% na região de saturação, respectivamente. Para os dispositivos FD o erro máximo observado, devido a variação nos parâmetros Naf e toxf, foi de 11% e 10% operando no regime linear, respectivamente e 5,3% e 8,4% no regime de saturação, respectivamente. Através do modelo proposto foi realizado o estudo da estabilidade do ponto ZTC em função da variação da degradação da mobilidade com a temperatura (fator c), comprimento de canal (L) e a tensão de dreno (VDS) para os dispositivos supracitados. A analise da influência do fator c em VZTC mostrou-se mais importante nos dispositivos parcialmente depletados (PD). A tensão VZTC, para os dispositivos nMOS, apresentou um menor valor operando na região de saturação, e torna-se mais pronunciada essa diferença para dispositivos com menor comprimento de canal, para ambos os tipos de dispositivos. Observando a variação de VZTC com VDS, nota-se uma diminuição no valor de VZTC para altos valores de VDS, para os dois tipos de dispositivos estudados, n e pMOS. Os resultados do modelo proposto foram avaliados com dados experimentais de outras tecnologias SOI MOSFET. Também foi obtido um bom ajuste com os valores para as tecnologias GC-SOI e GC-GAA SOI, operando em regime linear e saturação. / This paper presents a study of ZTC point (\"Zero Temperature Coefficient) in SOI MOSFETs devices, partially (PD-SOI) and fully (FD-SOI) depleted mode. The study is performed from a simple analytical model proposed for the determination of the gate bias voltage at ZTC point (VZTC) using the first-order models of the drain current (IDS) characteristics as a function of the gate voltage (VGF), operating in the linear and saturation regimes. To validate the model proposed results were compared with experimental data, and the analytical predictions are in very close agreement with experimental results in spite of the simplification used for the VZTC model proposed. Analysis was performed to study the impact on the VZTC value with the change in the parameters used as reference, such as Naf and toxf. The maximum error observed for the PD devices is 3.1% and 4.6% in the linear region and 3.5% and 7.2% in the saturation region, respectively. For FD devices the maximum error observed was 11% and 10% operating in the linear and 5.3% and 8.4% in the saturation regime. In order to verify the stability of the ZTC point as a function of the mobility degradation (c), channel length (L) and drain voltage (VDS), the proposed model was applied to the devices mentioned above. The VZTC changes in the temperature range investigated showed a temperature mobility degradation dependence and are more pronounced in PD devices. The VZTC voltage for nMOS devices presented a lower value operating in the saturation region than in the linear region, and this difference becomes more pronounced to devices with smaller channel length for both devices, n and pMOS. Analyzing the VZTC variation with drain voltage (VDS), showed a decrease in VZTC value for higher VDS, for both studied devices. The model proposed results were evaluated using experimental data from other SOI MOSFET technologies. And also we have obtained for the GC SOI and GC-GAA-SOI technologies a very close agreement, operating in both regions, linear and saturation.

<p>Research on net-zero energy buildings (NZEBs) has been largely centered around improving building energy performance, while little attention has been given to indoor air quality. A critically important class of indoor air pollutants are nanoaerosols – airborne particulate matter smaller than 100 nm in size. Nanoaerosols penetrate deep into the human respiratory system and are associated with deleterious toxicological and human health outcomes. An important step towards improving indoor air quality in NZEBs is understanding how occupants, their activities, and building systems affect the emissions and fate of nanoaerosols. New developments in smart energy monitoring systems and smart thermostats offer a unique opportunity to track occupant activity patterns and the operational status of residential HVAC systems. In this study, we conducted a one-month field campaign in an occupied residential NZEB, the Purdue ReNEWW House, to explore how energy use profiles and smart thermostat data can be used to characterize indoor nanoaerosol dynamics. A Scanning Mobility Particle Sizer and Optical Particle Sizer were used to measure indoor aerosol concentrations and size distributions from 10 to 10,000 nm. AC current sensors were used to monitor electricity consumption of kitchen appliances (cooktop, oven, toaster, microwave, kitchen hood), the air handling unit (AHU), and the energy recovery ventilator (ERV). Two Ecobee smart thermostats informed the fractional amount of supply airflow directed to the basement and main floor. The nanoaerosol concentrations and energy use profiles were integrated with an aerosol physics-based material balance model to quantify nanoaerosol source and loss processes. Cooking activities were found to dominate the emissions of indoor nanoaerosols, often elevating indoor nanoaerosol concentrations beyond 10⁴ cm^-3. The emission rates for different cooking appliances varied from 10¹¹ h^-1 to 10¹⁴ h^-1. Loss rates were found to be significantly different between AHU/ERV off and on conditions, with median loss rates of 1.43 h^-1 to 3.68 h^-1, respectively. Probability density functions of the source and loss rates for different scenarios will be used in Monte Carlo simulations to predict indoor nanoaerosol concentrations in NZEBs using only energy consumption and smart thermostat data.</p>

Traditional supervised visual recognition methods require a great number of annotated examples for each concerned class. The collection and annotation of visual data (e.g., images and videos) could be laborious, tedious and time-consuming when the number of classes involved is very large. In addition, there are such situations where the test instances are from novel classes for which training examples are unavailable in the training stage. These issues can be addressed by zero-shot learning (ZSL), an emerging machine learning technique enabling the recognition of novel classes. The key issue in zero-shot visual recognition is the semantic gap between visual and semantic representations. We address this issue in this thesis from three different perspectives: visual representations, semantic representations and the learning models. We first propose a novel bidirectional latent embedding framework for zero-shot visual recognition. By learning a latent space from visual representations and labelling information of the training examples, instances of different classes can be mapped into the latent space with the preserving of both visual and semantic relatedness, hence the semantic gap can be bridged. We conduct experiments on both object and human action recognition benchmarks to validate the effectiveness of the proposed ZSL framework. Then we extend the ZSL to the multi-label scenarios for multi-label zero-shot human action recognition based on weakly annotated video data. We employ a long short term memory (LSTM) neural network to explore the multiple actions underlying the video data. A joint latent space is learned by two component models (i.e. the visual model and the semantic model) to bridge the semantic gap. The two component embedding models are trained alternately to optimize the ranking based objectives. Extensive experiments are carried out on two multi-label human action datasets to evaluate the proposed framework. Finally, we propose alternative semantic representations for human actions towards narrowing the semantic gap from the perspective of semantic representation. A simple yet effective solution based on the exploration of web data has been investigated to enhance the semantic representations for human actions. The novel semantic representations are proved to benefit the zero-shot human action recognition significantly compared to the traditional attributes and word vectors. In summary, we propose novel frameworks for zero-shot visual recognition towards narrowing and bridging the semantic gap, and achieve state-of-the-art performance in different settings on multiple benchmarks.

The overall aim of the research is contribute to a reduction in suicides within mental health services. This study will explore the learning process for mental health services following patient suicides in Northern Ireland (NI). It will focus on how the recommendations contained in Serious Adverse Incident reports, which are completed following all patient suicides, are translated into practice. The study will examine all SAI reports completed from January 2015 to December 2016. Focus groups with mental health professionals throughout NI will then be used to increase understanding of the enablers and barriers to effective implementation of these recommendations within mental health services.
