Abstract:
Les centres fer-soufre (Fe-S) sont des cofacteurs protéiques essentiels qui participent à un nombre important de fonctions cellulaires allant du métabolisme de l’ADN à la respiration mitochondriale. L’assemblage des centres Fe-S et leur insertion dans des protéines acceptrices requièrent l’activité d’une machinerie protéique dédiée. Bien que les protéines de la biogenèse des centres Fe-S soient conservées, plusieurs aspects fonctionnels et mécanistiques restent inconnus. Notre travail de thèse a consisté à caractériser les protéines mammifères de type A, ISCA1 et ISCA2, qui sont impliquées dans la biogenèse mitochondriales des centres Fe-S. En utilisant une approche couplant l’immunoprécipitation avec une analyse protéomique par spectrométrie de masse, plusieurs interactions protéiques d’ISCA1 et ISCA2 ont pu être identifiées. En plus d’une interaction entre ISCA1 et ISCA2, nous avons ainsi montré l’existence d’interactions spécifiques à chacune de ces protéines. Une approche de knockdown dans la souris via l’injection de virus adéno-associés, a permis de montrer l’absence de redondance fonctionnelle entre ISCA1 et ISCA2 puisque seul ISCA1 se trouve être nécessaire dans la maturation d’une catégorie de protéines à centre Fe-S<br>Iron-sulfur clusters (Fe-S) are essential cofactors involved in different cellular processes ranging from DNA metabolism to respiration. Assembly of Fe-S clusters and their insertion into acceptor proteins is performed by dedicated protein machineries. Despite the high conservation from bacteria to man, different functional and mechanistic aspects of the Fe-S biogenesis remain elusive. In the present work, the function of the two mammalian A-type proteins ISCA1 and ISCA2 that are implicated in Fe-S biogenesis was investigated in vivo. First, an extensive analysis coupling immunoprecipitations and mass spectrometry led to the identification of a direct binding between ISCA1 and ISCA2 as well as specific protein partners of each protein. Furthermore, knockdown experiments in the mouse using adeno-associated virus provided clear evidence of the non-redundant function of ISCA1 and ISCA2, since only ISCA1 was shown to be required for a specific subset of mitochondrial Fe-S proteins

Abstract:
In Inverse Synthetic Aperture Radar (ISAR) systems the motion of the target can be classified in two main categories: Translational Motion and Rotational Motion. A small degree of rotational motion is required in order to generate the synthetic aperture of the ISAR systems. On the other hand, the remaining part of the target&rsquo<br>s motion, that is any degree of translational motion and the large degree of rotational motion, degrades ISAR image quality. Motion compensation techniques focus on eliminating the effect of the targets&rsquo<br>motion on the ISAR images. In this thesis, ISAR image generation is discussed using both Conventional Fourier Based and Time-Frequency Based techniques. Standard translational motion compensation steps, Range and Doppler Tracking, are examined. Cross-correlation method and Dominant Scatterer Algorithm are employed for Range and Doppler tracking purposes, respectively. Finally, Time-Frequency based motion compensation is studied and compared with the conventional techniques. All of the motion compensation steps are examined using the simulated data. Stepped frequency waveforms are used in order to generate the required data of the simulations. Not only successful results, but also worst case examinations and lack of algorithms are also discussed with the examples.

Abstract:
O presente tema tem como principal objectivo caracterizar o conjunto de capacidades inerentes a uma unidade de Intelligence, Surveillance, Target Acquisition and Reconnaissance (ISTAR), designadamente os princípios de e mprego e o conceito de operação que lhe estão associados, e analisar de que forma os módulos da Bateria de Aquisição de Objectivos (BAO) poderão contribuir para a operacionalidade deste sistema. As actividades do sistema ISTAR são conduzidas em todo o espectro das operações militares e pode definir-se o sistema ISTAR como a aquisição coordenada, o processamento e difusão oportuna de notícias e Informações (precisas, relevantes e seguras), que apoiam o planeamento e a conduta das operações, o ataque a objectivos e a integração de efeitos (processo de targeting), contribuindo para que um Comandante possa atingir os objectivos operacionais de uma determinada operação. De forma a familiarizar o leitor com o vasto leque de conceitos efectuou-se uma revisão de literatura que inclui, de forma concisa e objectiva, o ponto de situação dos vários conceitos que a temática em causa engloba, tendo em conta a doutrina nacional assim como os princípios e o conceito de operação que lhes estão associados. Numa fase seguinte incide-se nas experiências pessoais e casos de estudo, para expor a situação nacional, analisando-se a BAO de uma forma mais pormenorizada, quer a nível da sua orgânica, como a nível de modularidade e centralização. Posteriormente fez-se um levantamento de um conjunto de capacidades inerentes a uma unidade ISTAR tipo, no sentido de materializar a mesma no seio do nosso Exército . No final apresentam-se as conclusões resultantes desta investigação, no sentido de dar resposta à questão central levantada, da qual se destaca a necessidade de reequipar o Pelotão Radar de Localização de Armas (RLA), o Pelotão Radar Localização de Alvos Móveis (RLAM) e a Secção Meteorológica para que estes adquiram as capacidades decorrentes das OTAN Capability Statements das Force Proposal 2008 (FP 08). Faltam ainda levantar as capacidades em termos de Unmanned Aerial Vehicle (UAV) e Sensores Acústicos.<br>Abstract This theme has as main objective to characterize the set of capabilities inherent to an ISTAR unit, namely the principles of employment and operational concept, associated with it and consider how the modules of the BAO may contribute to the operation of this system. ISTAR activities are conducted in all spectrums and the operations can be defined as the coordinated acquisition, processing and dissemination of timely, accurate, relevant and assured information and intelligence which supports the planning and conduct of operations, targeting and the integration of effects and enables commanders to achieve their goals throughout the spectrum of conflict. In order to familiarize the reader with a broad range of concepts, a literature review that includes a concise and objective current status of the various concepts included in the topic question, taking into account the national doctrine and the principles and concept of operations associated with it. In a next step, we focus on personal experiences and case studies to expose the national situation. The BAO is also analyzed in more detail, both in terms of its organization, both in terms of modularity and centralization. Subsequently we conducted a survey of a set of capabilities inherent in an ISTAR unit type, in order to materialize the same within our Army. In the end we present findings from our research in order to answer the central question raised by us, which highlights the need to retool the Weapon Locating Radar Platoon, the Ground Surveillance Radar Platoon and the Meteorological Section. There are still to raise the capability in terms of Acoustic Weapon Locator and UAV.

Thesis (MBA)--Stellenbosch University, 2000.<br>ENGLISH ABSTRACT: It was found that the hot metal cost of ISCOR Newcastle's single blast furnace can significantly be reduced by the correct use of an integrated model to predict reductant cost based mainly on coal blend. The model uses coal ash chemistry, fluiidity, vitrinite rank and volatile matter to predict coke strength after reaction (CSR), coke ash and coking yield. CSR is used to predict maximum allowable coke nut- and pea consumption in the furnace as well as hot blast temperature. Pitch injection levels are predicted using CSR and blast furnace production rates. Coke ash, pitch injection and hot blast temperature is used to predict the coke rate. The above is used with imported Chinese coke cost to accurately predict reductant cost. It was found that the current optimum blends should include Australian en Nieu Zeeland coals because of price and quality conciderations. Because of its low cost of production and low quality the optimum percentage of Grootegeluk in the blend is determined largely by its transfer price.<br>AFRIKAANSE OPSOMMING: Die vloeiyster koste van ISCOR Newcastle se enigste hoogoond kan drasties verlaag word deur die korrekte gebruik van 'n geïntegreerde model wat reduktant koste voorspel op grond van steenkoolmengsel. Die model gebruik die chemiese samestelling van steenkool-as, fluiiditeit, vitriniet rang en vlugstof om kooks warmsterkte (SNR), kooks-as en verkooksingsopbrengs te voorspel. SNR is gebruik om die maksimum kooksneute- en -erteverbruik in die hoogoond sowel as blaastemperatuur te voorspel. Pikinspuiting is bereken met SNR en hoogoond produksietempo's. Pikinspuiting en blaastemperatuur word saam met kooks-as gebruik om kookskoers te voorspel. Bogenoemde is saam met die koste van ingevoerde Chinese kooks gebruik om reduktant koste akkuraat te voorspel. Daar was bevind dat die huidige optimum mengsels Australiese en Nieu Zeelandse steenkool moet bevat as gevolg van huidige prys- en kwaliteitsoorwegings. As gevolg van sy lae produksiekoste en lae kwaliteit word die optimum hoeveelheid Grootegeluk bepaal deur sy oordragprys.

Os modelos i* relacionam todo os participantes envolvidos (atores, agentes, papéis e posições) através de relacionamentos de dependências estratégicas e intenções (metas, tarefas, metas brandas e recursos). Ao longo dos anos, relatos científicos descrevem estudos sobre o iStar (i*) e variações dessa linguagem e apontam que, fundamentalmente, a linguagem i* tem sido usada para modelar diferentes domínios, tais como telecomunicações, controle de trafego aéreo, dentre outros. Entretanto, nesses estudos, constatou-se que vários pontos fracos e limitações podem ser observados na linguagem i*, como por exemplo: falta de padronização, diferentes métodos de modelagem, falta de reusabilidade, ferramentas não profissionais, e, dentre outros muitos desafios, destaca-se a escalabilidade de seus modelos, segundo reconhecidos pesquisadores desta área de estudo. Assim, esta pesquisa mapeia estudos que abordaram a questão da escalabilidade do i* e tem como por objetivo conhecer: distribuição desses estudos, definições sobre a escalabilidade do i*, menções para contribuições que tratem do assunto, os julgamentos sobre a escalabilidade do i*, e, questões abertas relacionadas a esse tema. Todas as informações foram obtidas a partir de um estudo realizado sob a forma de mapeamento sistemático da literatura, tendo por base um protocolo com foco na escalabilidade do i*. Os estudos retornados foram filtrados por critérios de exclusão, inclusão, qualificação e agrupamento das publicações. Os dados foram extraídos desses estudos para apoiarem na síntese e a responder às perguntas de pesquisa propostas. No total, foram encontrados 119 estudos sobre escalabilidade de i*, dos quais, onze deles tiveram como foco central a escalabilidade do i* propriamente dita, enquanto dez estudos possuíam definição para o termo escalabilidade. Assim, nove estudos foram considerados como de melhor cobertura para responder as perguntas de pesquisa. No geral, foram identificadas 150 menções à contribuições associados a escalabilidade do i*. Em relação a facilidade de se escalar o i*, 62 dos 119 estudos afirmaram que i* não possui uma escalabilidade bem tratada, enquanto que em 93 desses mesmos 119 estudos, foram identificadas questões em aberto quanto à escalabilidade do i*. O mapeamento realizado sintetiza quais estudos possuem informações sobre a escalabilidade do i*. Isto será útil para pesquisas futuras, por facilitar agrupamento e identificação de potenciais fontes de dados e publicações, apesar de notar-se que a cobertura dos estudos precisa ser melhorada, pois apenas 9 dos 119 estudos avaliados, de fato, contribuíram mais com as perguntas de pesquisa realizadas. Por fim, as definições de escalabilidade e lista de publicações com contribuições permitirão comparações e reuso de técnicas para escalar modelos i*.<br>The iStar language (i*) is a modeling framework applied in Requirements Engineering which was proposed two decades ago. The i * models relate all the participants involved (actors, agents, roles and positions) through relationships of strategic dependencies and intentions (goals, tasks, soft goals and resources). Over the years, scientific reports describe studies on the iStar (i*) and variations of this language and point out that, fundamentally, the i* language has been used to model various domains such as telecommunications, air traffic control, among others. However, in these studies, it was found that several weaknesses and limitations may be observed in the language i *, for example, lack of standardization, different methods of forming, lack of reusability, nonprofessional tools and, among many other challenges we highlights the scalability of their models according to recognized researchers in this study area. Thus, this research maps studies that addressed the question of scalability of the i* and it has as objective to meet: distribution of these studies, settings on the scalability of i *, references to contributions dealing with the subject, the judgments about the scalability of i *, and open issues related to this theme. All information was obtained from a study conducted in the form of systematic mapping of literature, based on a protocol focusing on the scalability of the i*. The studies returned were filtered by criteria for exclusion, inclusion, qualification and grouping of publications. The data were extracted from these studies to support the synthesis and answering to the proposed research questions. In total, were found 119 studies on the i* scalability, of which eleven of them had as its central focus the scalability of i* itself, while ten studies had definition for the term scalability. Thus, nine studies were considered to be of better coverage to answer the research questions. Overall, 150 indications were identified to the contributions associated with the i* scalability. Regarding the ease of scale the i*, 62 of these 119 studies stated that the i* does not have a scalability treated well, while in 93 of those 119 studies were identified open issues regarding the scalability of i*. The mapping performed summarizes what studies have information about the scalability of the i*. This will be useful for future research by facilitating grouping and identification of potential data sources and publications, though noted that the coverage of the studies need to be improved, because only 9 of 119 studies evaluated, actually contributed more to the research questions carried out. Finally, the scale settings and list of publications with contributions will allow comparisons and reuse techniques for scale the i* models.

Abstract:
A proper time-frequency transform technique suppresses the blurring and smearing effect of the time-varying Doppler shift on the target image. The conventional target imaging method uses the Fourier transform for extracting the Doppler shift from the received radar pulse. Since the Doppler shift is timevarying for rotating targets, the constructed images will be degraded. In this thesis, the Doppler shift information required for the Range-Doppler image of the target is extracted by using high resolution time-frequency transform techniques. The Wigner-Ville Distribution and the Adaptive Gabor Representation with the Coarse-to-Fine and the Matching Pursuit Search Algorithms are examined techniques for the target imaging system. The modified Matching Pursuit Algorithm, the Matching Pursuit with Reduced Dictionary is proposed which decreases the signal processing time required by the Adaptive Gabor Representation. The Hybrid Matching Pursuit Search Algorithm is also introduced in this thesis work and the Coarse-to-Fine Algorithm and the Matching Pursuit Algorithm are combined for obtaining better representation quality of a signal in the time-frequency domain. The stated techniques are applied on to the sample signals and compared with each other. The application of these techniques in the target imaging system is also performed for the simulated aircrafts.

Abstract:
In this thesis, Inverse Synthtetic Aperture Radar image reconstruction techniques, named as Range Doppler, Back Projection, Polar Formatting, Multiple Signal Classification (MUSIC) and Time Frequency techniques are analysed and compared using simulations. Time Frequency techniques investigated in this thesis are Short Time Fourier Transform, Wigner-Ville Distribution, Smoothed Wigner-Ville Distribution and Choi-Williams Distribution. First, some fundamental concepts of ISAR, such as resolution, range profile, time dependent Doppler frequency are given. A data simulator is designed and implemented for the purpose of providing configurable input to ISAR signal processing algorithms for a given ISAR target geometry. Estimation of target rotational velocity is explained with the help of three methods, namely Grid Search, WVD Slope and Radon Wigner-Hough Transform. Then, theoretical background of image formation algorithms is discussed. MATLAB simulations for each algorithm are implemented with several configurations in order to visualize and analyse the results. Finally, processing algorithms are compared to discuss the advantages and disadvantages.

Thesis: M. Eng., Massachusetts Institute of Technology, Department of Electrical Engineering and Computer Science, February 2014.<br>Cataloged from PDF version of thesis. "November, 2013."<br>Includes bibliographical references (pages [137]-139).<br>A frequently useful technique in the interpretation of Inverse Synthetic Aperture Radar (ISAR) images is to construct a three dimensional (3D) model of the object being imaged. Generally, such models are constructed manually by an analyst based on a series of radar images and whatever other information is available. However, using multistatic radar, it is possible to generate 3D Interferometric ISAR (IFSAR) point cloud images. In this thesis, two original techniques for automatically generating models of rigid bodies from IFSAR point clouds are explored. One technique extends the concept of the visual hull to a composite point cloud. The other uses a noise resistant estimator to determine the shape of the side of the object presented to the radar. Noise and radar artifacts show up strongly in the data, and both techniques must reject them to achieve good performance. Additionally, an optimization-based algorithm was devised to determine the angular velocity of a target using only one interferometric baseline. Knowing the angular velocity of the target is necessary to correctly scale the axes of ISAR images and IFSAR point clouds. Though techniques exist for angular velocity determination using multiple baselines, receiving antennas are expensive and are not always available. The techniques presented in this thesis were tested against simulated data and data collected in a compact range. The angular velocity determination technique was successfully demonstrated on simulated IFSAR data, using a particular heuristic enforcing the consistency of rotational motion. Investigation into a more robust heuristic is necessary to make the approach broadly effective. The surface reconstruction algorithm based on the noise resistant estimator performs very well, doing much better than a traditional algorithm selected for comparison (3D a-shapes) in high noise situations. The technique based on the visual hull, while producing faithful reconstructions in some cases, generally offers performance inferior to the noise resistant estimator. Quantitative measurements were used to evaluate the fidelity of the models generated by the various techniques.<br>by Neil T. Forrester.<br>M. Eng.

Abstract:
Thesis (MBA)--Stellenbosch University, 2000.<br>Iscor Mining is facing key challenges due to the intensification of international market competition, deteriorating commodity prices and escalating input costs. Its parastatal history and protected environment during the years of isolation, was not a conducive environment for the development of a high performance organisation. Iscor management recognised this challenge and embarked on a programme to kick-start improvement on all its operating units. This programme delivered on expectations, but signs of weaknesses in the organisation's ability to sustain the improvements were starting to emerge. The potential for further improvements were shown to be far more than anticipated, however the organisation was limited by cultural and leadership issues in its ability to turn the identified performance improvement potential into business results and shareholder value. The existing organisational capabilities were evaluated for its potential to unlock the identified value against a chosen management model, and the areas of biggest concerns identified were in leadership behaviour, business process design and organisation culture. The biggest gaps in organisational capabilities were shown to exist in areas of leadership, core business process design and organisational culture issues. Thirteen actions for change is proposed to close the identified gaps.

Esses sistemas s?o complexos por conta do grande n?mero de partes que interagem de modo n?o simples, dada as propriedades dessas partes e das leis que regem essas intera??es. Al?m dessa circunst?ncia, trabalhos da Engenharia de Software refor?am que o universo das informa??es necess?rias para realizar uma modelagem ? mais amplo, e envolve mais dimens?es das j? consolidadas: est?tica e din?mica. Assim, surge o framework iStar com uma ontologia delineada para capturar e representar informa??es intencionais e sociais do ambiente analisado em dois modelos gr?ficos: Depend?ncia Estrat?gica (SD - Strategic Dependency ) e Racioc?nio Estrat?gico (SR - Strategic Rationale ). Entretanto, esse mesmo framework n?o oferece alternativas para melhorar a compreens?o dos seus modelos gr?ficos, quando esses representam um grande n?mero de partes desses ambientes, ou seja, sistemas complexos. Diante disso, o objetivo desta disserta??o foi oferecer uma alternativa ao framework iStar para lidar com a complexidade proporcionada pelos sistemas complexos, desta forma, influenciar positivamente a compreens?o e o aprendizado dos modelos iStar. Com esse fim, foi desenvolvida uma nota??o textual para compreender as informa??es sociais atrav?s de uma estrutura interdependente. Na avalia- ??o desenvolvida, observou-se a relev?ncia dessa nota??o textual para os modelos gr?ficos da seguinte forma: (i) uma alternativa complementar para leitura dos modelos gr?ficos, como tamb?m, (ii) a import?ncia da constru??o desses modelos a partir de composi??es de estruturas interdependentes.<br>A modern society, progressively, provides increasingly sociotechnical environments through of complex systems. This complexity is to due to the large number of parties interacting in a non-simple way, given the properties of these parts and the laws governing these interactions. In addition to this circumstance, the Software Engineering reinforces that the universe of information needed to perform a broader modeling, and involves more dimensions of already consolidated: static and dynamic. Thus, the iStar framework emerges with an ontology capable of capturing and represent intentional and social information of the environment analyzed in two graphic models: Strategic Dependency (SD) and Strategic Reasoning (SR). However, this same framework does not offer alternatives to improve the understanding of its graphic models, when these represent a large number of parts of these environments. Therefore, the objective of this dissertation was to offer an alternative to the iStar framework to deal with the complexity provided by the complex systems, in order to positively influence the understanding and learning of the iStar models. To this end, a textual notation has been developed to understand social information through an interdependent structure. In the developed evaluation, it was observed the relevance of this textual notation for the graphic models as follows: (i) a complementary alternative for reading of the graphic models, as well as (ii) the importance of building these models from interdependent structures.

Abstract:
O presente trabalho de Investigação, com o título “O Sistema ISTAR e as Unidades de Reconhecimento do Sistema de Forças Nacional”, tem como enfoque principal a Unidade de Reconhecimento existente no Sistema Intelligence, Surveillance, Target Acquisition and Reconnaissance (ISTAR) e as Unidades de Reconhecimento do Sistema de Forças Nacional (SFN), com o intuito de entendermos quais as alterações que a criação desta Unidade de Reconhecimento poderá provocar nas já existentes ou vice-versa. Na primeira metade do Trabalho aborda-se o Sistema de uma forma genérica, fazendo a descrição dos seus elementos, componentes, princípios e estrutura. Aborda-se ainda as Unidades de Reconhecimento existentes no SFN quanto à sua orgânica e constituição. De seguida apresenta-se a evolução do processo de implementação do ISTAR em Portugal e por fim o sistema ISTAR em países de referência, tais como Holanda e Estados Unidos da América (EUA). Na segunda metade foram realizadas as entrevistas com diversos oficiais envolvidos directa ou indirectamente na implementação do Batalhão ISTAR (BISTAR). Estas entrevistas realizaram-se com o intuito de obter uma opinião rigorosa acerca das possíveis alterações que poderão surgir ao nível das Unidades de Reconhecimento (Rec), para a sua melhor interligação com o Batalhão. Assim, após as analises às entrevistas conclui-se que no que diz respeito a meios e organização os Esquadrões actuais estão prontos para a sua integração no Sistema ISTAR, mas quando aos procedimentos nos referimos, estes terão de sofrer algumas actualizações para que essa integração ocorra da melhor forma.<br>Abstract This research work, entitled "The ISTAR System and the Reconnaissance Units of the National Forces System", has as its primary focus the existing Reconnaissance Unit in Intelligence, Surveillance, Target Acquisition and Reconnaissance (ISTAR) System and Reconnaissance Units of National Forces System (NFS), in order to understand what changes the creation of this unit may result in recognition of existing or vice versa. In the first half of the work deals with the system in a generic way, making the description of its elements, components, principles and structure. It also covers the recognition of existing units in the NFS and its organization and constitution. Then deals with the implementation progress of ISTAR in Portugal and finally the ISTAR system in reference countries such as Holland and the United States of America (USA). In the second half interviews were conducted with several officials involved directly or indirectly in the implementation of the ISTAR Battalion. These interviews were held with the aim of get an accurate opinion on possible changes that may arise to the Reconnaissance Units for the better interconnection with the Battalion. Thus, after the interviews analysis it was concluded that with regard to means and organization the current squads are ready for their integration into the ISTAR system, but that when we refer to the procedures they will have to undergo some updates for this integration will be the best way.

The patterns of spatial distribution of nests over a 1800m2 degraded area in the city of Rio Claro, SP, Brazil were determined using a nearest neighbor method. As in most tropical species, the nests of E. opaciventre presented a regular or hyperdispersed spatial distribution, with a density of 0.018 nests/m2. The average nearest neighbor distance was 5.57 m, ranging from 1.93 m to 12.96 m. Considering the difficulty in finding queens of this species, the Fourier Transform-Infrared Photoacoustic Spectroscopy (FTIR-PAS) was used to identify cuticular hydrocarbons of the only queen found and of workers from nine satellite nests. The degree of similarity between them was also determined. From the results, polydomy was evident in this species because of the similarity between the cuticular chemical profile of the queen and that of workers from neighboring nests. Moreover, it was observed that the colonies that were not collected disappeared one year after the removal of the queen from the study area. In another area in the city of Rio Claro, of 4,800 m2, the diet of this species was studied by identifying the prey collected during the period of highest foraging activity.

In this thesis a stepped-frequency Inverse Synthetic Aperture Radar (ISAR) is employed to develop two-dimensional range-Doppler images of a small ghter aircraft which exhibits three dimensional rotational rotation. The simulation is designed such that the target can exhibit yaw, pitch and roll motions at the same time. First, radar returns from prominent scatterers of various parts of the target are processed and displayed using conventional Fourier transform. The eects of dierent complex motion types and scenarios are observed and discussed. Then, several linear and bi-linear time-frequency distributions including shorttime Fourier transform, Wigner-Ville, pseudo Wigner-Ville, smoothed pseudo Wigner-Ville, Choi-Williams, Born-Jordan and Zhao-Atlas-Marks distributions are applied to the same target and scenarios. The performance of the transforms is compared for each scenario. The reasons for success of the distributions are discussed thoroughly.

Abstract:
Doutoramento em Biologia<br>A prevalência de bactérias resistentes a antibióticos em ambiente hospitalar tem vindo a tornar-se dramática e preocupante a nível mundial. Contudo, com a utilização inadequada de antibióticos em áreas tão diversas como a veterinária, a aquacultura e a agricultura, esta deixou de estar confinada ao ambiente hospitalar, sendo o ambiente um reservatório natural de microganismos resistentes a estes compostos. O conhecimento detalhado dos determinantes de resistência a antibióticos presentes nestes ambientes, sejam estes genes de resistência ou estruturas envolvidas na sua mobilização, é fundamental, não só do ponto de vista do conhecimento como para a eventual implementação de medidas de contenção da sua disseminação. Neste contexto, são necessários estudos que permitam conhecer o panorama mais realista da distribuição destes determinantes de resistência a antibióticos, quer no meio ambiente quer no ambiente clínico. Assim, constituiu objectivo principal deste trabalho contribuir para o conhecimento do panorama actual da prevalência e distribuição dos elementos ISCR, bem como de outros determinantes de resistência a antibióticos em espécies de Gram-negativo clinicamente relevantes (Escherichia coli, Klebsiella pneumoniae, Acinetobacter baumannii e Citrobacter freundii) recolhidas a partir de amostras de pacientes do Hospital Infante D. Pedro, EPE, Aveiro, Portugal, entre 2006 e 2008. Adicionalmente, foram também recolhidas bactérias de Gram-negativo do meio ambiente, a partir de amostras de águas e de vísceras de peixes, nas quais foram igualmente pesquisados os elementos acima referidos. À excepção dos isolados de E. coli e de Gramnegativo ambientais, todas as estirpes estudadas foram seleccionadas com base no seu perfil de multirresistência a antibióticos. Os resultados mostraram que em todas as espécies recolhidas no ambiente hospitalar foi detectada a presença de elementos ISCR, do tipo ISCR1 ou ISCR2. O elemento ISCR1, foi encontrado em isolados de E. coli, K. pneumoniae e C. freundii e o elemento ISCR2 em isolados de A. baumannii. Não foi detectada a presença de ISCRs nos isolados de Gram-negativo ambientais, o que sugere que a ocorrência dos mesmos é fortemente influenciada pela pressão selectiva exercida pelo ambiente em que os microrganismos se encontram. Genes qnr e integrões de classe 1 foram os determinantes de resistência mais frequentemente encontrados associados aos elementos ISCR1. Os vários determinantes de resistência foram encontrados em diferentes contextos genéticos e localizados em estruturas móveis, nomeadamente em plasmídeos. O elemento ISCR2 presente em isolados de A. baumannii encontra-se associado ao gene sul2 em todos os isolados, dentro de um mesmo contexto genético e com uma localização cromossomal. Contudo, o contexto genético encontrado nestes isolados é novo não tendo sido descrito até à data em outros microrganismos. O presente estudo constitui a primeira descrição de elementos ISCR intrinsecamente ligados a genes de resistência a antibióticos, em Portugal. Uma vez que estes elementos parecem ser responsáveis pela mobilização de um grande número de genes de resistência a antibióticos, a sua elevada incidência entre estirpes resistentes e multirresistentes, bem como a sua associação com genes de resistência é preocupante e requer vigilância.<br>Within the hospital environment, antibiotic resistant bacteria are a problem of concern worldwide. However, the antibiotic resistance has breached outside the confined hospital environment due to an inappropriate and intensive use of antibiotics in areas such as veterinary, aquaculture and agriculture, being the natural environment also a reservoir of antibiotic resistant microorganisms. Accurate and detailed studies focusing on the existing resistance determinants, either resistance genes or structures enhancing/involved in their dissemination, is needed in order to provide a realistic scenario of their distribution as well as for the implementation of measures that could prevent the dissemination of those genes. Thus, studies giving a wider and realistic panorama of the distribution of antibiotic resistance genes in both the natural and the hospital environment are of utmost importance. The main goal of this thesis was to contribute to the present knowledge of distribution and prevalence of antibiotic resistance genes and ISCRs elements in clinically relevant Gram-negative species (Escherichia coli, Klebsiella pneumoniae, Acinetobacter baumannii and Citrobacter freundii) collected from clinical specimens from patients in the Hospital Infante D. Pedro, EPE, Aveiro, Portugal between 2006 and 2008. Additionally, environmental Gram-negative isolates, collected from water and fish guts were also screened for the presence of the ISCR elements. All the isolates that were included in the present study were multi-drug resistant, with the exception of Escherichia coli and the Gram-negative environmental isolates. The results obtained revealed that the ISCR1 and ISCR2 elements were present in all the species collected within the hospital settings. ISCR1 was present in E. coli, K. pneumoniae and C. freundii isolates and ISCR2 was detected in the A. baumannii isolates. The presence of ISCRs was not detected among the environmental Gram-negative isolates, suggesting that the occurrence of ISCR is clearly biased by the pressure exerted by the environment from where the microorganisms were isolated. qnr genes and class 1 integrons were the main resistance determinants found associated with ISCR1 and were both described in different genetic contexts, located on mobile structures such as plasmids. Moreover, the ISCR2 element was found associated with the sul2 gene in all the A. baumannii isolates with the same genetic context and located on the chromosome. Noteworthy is that the genetic context described is unique and was never described before in other microorganisms. This is the first study reporting the presence of ISCR elements in Portuguese isolates. Since these elements are responsible for the mobilization of several antibiotic resistance genes and were found intrinsically linked to them, their high incidence, among multi-drug resistant isolates is disconcerting and requires surveillance.

Abstract:
Steel producers in South Africa are finding it increasingly difficult to achieve long term goals due to the level of competition in the industry domestically, as well as being under threat from overseas producers. The objective of the study was to research customer service in order to formulate a model for the successful implementation of a customer service programme. The present level of expectation and perception of customer service was established by making use of the Servqual questionnaire. The outcome of the questionnaire showed a value of -0,73, which is below the zero point, where customer perceptions meet their expectations. A model for the successful implementation of a customer service programme was recommended. This model consists of five points i.e. establishing of organisational values and goals, determination of the present state of customer satisfaction, the identification of causes relating to the poor levels of service, the implementation of actions to rectify the poor levels of service and measuring and monitoring of these actions. It was recommended that with the total commitment from top management, a program can be successfully launched that will lead to a change in the approach to customer service and an improvement in the level of service to customers.<br>MBA, Potchefstroom University for Christian Higher Educations, 2000

Abstract:
Les ISCR constituent une famille de séquences d’insertions bactériennes décrits récemment dans des contextes cliniques et d’antibiorésistance. Les transposases codées par ces IS appartiennent à la famille des HUH transposases qui transposent selon un mécanisme en cercle roulant. Néanmoins, aucune donnée expérimentale n’existe à ce jour. La famille ISCR compte 19 membres mais ont été peu caractérisés. C’est pourquoi, nous avons fait une mise à jour des informations sur ces éléments en analysant in silico les principales caractéristiques par une étude in silico. Nous nous sommes ensuite intéressés à l’implication de l’élément ISCR1 dans l’expression de la région variable en aval. Cet élément contient deux promoteurs orientés vers l’extérieur (POUT) dans sa région en 3’. Après une analyse de la diversité des gènes, nous avons remarqué que la plupart des gènes en aval étaient orientés dans le même sens que ces POUT et qu’ils pouvaient être exprimés à partir des deux promoteurs. Nous avons montré que pour deux gènes de résistance dfrA19 et blaCTX-M-9, ces promoteurs augmentent le niveau d’expression. De plus, la région contenant les deux promoteurs est nécessaire pour que l’expression de blaCTX-M-9 confère un phénotype de résistance. En parallèle, nous avons déterminé la régulation du promoteur du gène de la transposase de ISCR1. Nous avons identifié des motifs de régulation pour les régulateurs LexA et OmpR et déterminé expérimentalement que le promoteur du gène de la transposase de ISCR1 était régulé de façon négative par la protéine LexA, régulateur majeur de la réponse SOS et de façon positive par la protéine OmpR en conditions hypo-osmotiques. Nous proposons donc un modèle selon lequel ISCR1 est un élément dont la mobilité serait conditionnée par des facteurs environnementaux et en même temps, assurerait l’expression constitutive de gènes en aval, notamment impliqués dans l’antibiorésistance<br>ISCR are a bacterial insertion sequences, recently described in clinical settings, frequently related to antibiotic resistance. These ISCR-encoded transposases belong to the well-known HUH transposases family, which transpose by rolling-circle replication. However, the transposition mechanism of ISCR transposases has not been shown experimentally. ISCR family includes 19 members and has not been well characterized yet. Therefore, we updated in silico already known characteristics for each ISCR element. Then, we investigated the involvement of ISCR1 in the expression of the downstream genes. Indeed, ISCR1 carries two outward-oriented promoters called POUT. By analyzing the diversity of the downstream region, we found that most of genes were in the same orientation as POUT promoters, suggesting these downstream genes are expressed from POUT. It thus showed that these two promoters are able to express two antibiotic resistance genes (dfrA19 and blaCTX-M-9 ). Moreover, the region containing POUT is essential to provide an ESBL-resistance phenotype for blaCTX-M-9 gene. Moreover, we also wanted to analyze the regulatory network involved in the expression of the ISCR1 transposase, RCR1. We experimentally determined that two regulatory proteins LexA and OmpR, involved in response to different stress (DNA damages and osmotic shock), control the activity of rcr1 promoter. LexA protein represses Prcr1 whereas OmpR activates Prcr1 in hypo-osmotic conditions. Here, we propose a model in which ISCR1 transposition would be the control of environmental stresses and at the same time, insured the expression of downstream antibiotic resistance genes

Abstract:
This thesis integrates Shariah Law as an additional layer of regulations and Islamic Perspective of Accounting (IPA) framework to examine of the relation between Islamic Social Disclosure (ISCR) and Earnings Quality (EQ) of Malaysian public-listed companies. Five empirical studies were undertaken. First, accruals quality models suggested by previous researchers in the UK and the USA (Jones, 1991; Modified Jones, 1995; Dechow and Dichev 2002; McNichols, 2002) have been examined and reviewed in the new dataset; and McNichols model has been identified as the model that could accurately measure the quality of earnings reported. Second, the level of EQ has been examined. The multivariate analysis revealed that additional regulatory and cultural factors, and specifically the ethnicity of the chairperson, influenced the level of EQ. It was also found that there were variations in the level of EQ from year 2000 to year 2007. The largest contribution to this variation in year 2007 originated from the Delisted and Listed (DLL) group of companies. Third, the level of ISCR has been investigated and on average, the Product and Services theme scored the highest for disclosure (63%), followed by the Environment theme (55%), Community theme (39%), and Employees theme (27%). Fourth, the same range of factors tested to examine EQ has been specifically investigated against the ISCR score. The variables corresponding to institutional investors, top-ten shareholders, size of auditor and firm‟s involvement in foreign activities had a significant relationship with the ISCR. Fifth, the relationship between EQ and ISCR was examined. The results from the two-stage least squares (2SLS) method of analyses provided evidence that firms with poor earnings quality were more likely to disclose more social information. The contributions of this study include: i) a new research setting provides new research evidence on the effect of regulation regarding the EQ and ISCR issues; ii) the McNichols model and the modified ISCR checklist could be used by the stakeholders or other researchers to assess the situation of the Malaysian companies; iii) when the IPA framework is incorporated in the discussions together with Institutional theory, Environmental Determinism theory, Agency theory, Signalling theory, Stakeholder theory, and Legitimacy theory, it contributes to the richness of the existing literature; and iv) the findings regarding the relationship between EQ and ISCR indicates that the delivery of financial and non-financial information could still be improved to demonstrate the sense of responsibility and accountability of the management towards God (Allah) and towards the stakeholders.

Abstract:
Approved for public release; distribution in unlimited.<br>An imaging radar, like ISAR, offers a combatant the capability to perform long range surveillance with high quality imagery for positive target identification. Extending this attractive feature to the battle damage assessment problem (BDA) gives the operator instant viewing of the target's behavior when it is hit. As a consequence, immediate and decisive action can be quickly taken (if required). However, the conventional Fourier processing adopted by most ISAR systems does not provide adequate time resolution to capture the target's dynamic responses during the hit. As a result, the radar image becomes distorted. To improve the time resolution, time-frequency transform (TFT) methods of ISAR imaging have been proposed. Unlike traditional Fourier-based processing, TFT's allows variable time resolution of the entire event that falls within the ISAR coherent integration period to be extracted as part of the imaging process. We have shown in this thesis that the use of linear Short Time-Frequency Transforms allows the translational response of the aircraft caused by a blast force to be clearly extracted. The TFT extracted images not only tell us how the aircraft responds to a blast effect but also provides additional information about the cause of image distortion in the traditional ISAR display.

A mortalidade foi registrada após um, dois, quatro, seis, 12, 24 e 48 horas nos tratamentos e nos controles: xarope e atraentes da isca sem ativo. Cinco gramas das iscas foram disponibilizadas no campo às abelhas em pratos plásticos junto com o xarope (alimento com 30% de à açúcar) ao nível do solo. O número de abelhas que pousaram sobre as iscas, foi registrado a cada 30min em seis observações por dia e comparado com o daquelas atraídas no controle (mel à 50%).

The objective was to determine the toxicity and attraction of the baits to Apis mellifera (Hymenoptera: Apidae). Operators of this bee were exposed by ingestion of 50% sugar solution (syrup) with fipronil or sulfluramide and by direct contact and inhalation of the volatiles of the formicidal baits with each experimental unit 10 bees/pot. The mortality was registered after one, two, four, six, 12, 24 and 48 hours in the treatments and in the controls: syrup and attractive of the bait without assets. Five grams of the baits were made available in the field to the bees in plastic plates with the syrup (feed with 30% of the her sugar) at the level of the soil. The number of bees that landed on the baits was recorded every 30 minutes in six observations per day and compared to those attracted to the control (honey at 50%). The survival of forages of A. mellifera was lower with the concentrations of fipronil bait with oral LD 50 48 h of 54.5 ± 12.9 μg bait/bee. Bees exposed by ingestion of the solution with the formicidal sulfluramide bait had similar survival to that of the control. The mortality of bees after 48 hours of direct contact with the baits was >86.0%, with a lethal effect of the volatiles of the bait with sulfluramide (contact or inhalation), greater than the control. The number of forage bees that posed on the baits formulated with fipronil and sulfluramide oscillated between 11.0 and 0.0, lower than those attracted in the control (honey at 50%) 143.0 to 114.3. Baits formicidal with fipronil and sulfluramida are “dangerous and little dangerous” respectively, for A. mellifera by ingestion. It has toxic potential by direct contact and with the volatiles of the bait with sulfluramida, but in the field the bees were not attractive.

Abstract:
Mestrado em Administração e Gestão Pública<br>Nas últimas décadas, as organizações públicas têm sido pressionadas para que os seus serviços se tornem mais transparentes, responsáveis e próximos dos cidadãos, de modo a satisfazer as suas expectativas e necessidades prestando um melhor serviço público. A pressão para esta mudança resulta da mundialização da economia, do desenvolvimento das Tecnologias da Informação e Comunicação, da redefinição de fronteiras e da alteração da ligação entre o Estado e a Sociedade. Esta transformação tem-se traduzido na descentralização de competências, maior atenção atribuída às exigências sociais decorrentes da crise económica, crescente exigência dos cidadãos para com os governantes, desburocratização e racionalização dos serviços públicos. Neste contexto, os gestores públicos terão de enfrentar grandes desafios para transformar a Administração Pública e adequá-la a uma sociedade mais informada e exigente. O recurso a práticas, ferramentas e modelos utilizados no setor privado decorre precisamente da pretensão de melhorar substancialmente a qualidade dos seus serviços, procurando colocá-los ao nível dos melhores do setor privado. A avaliação de desempenho é uma destas práticas. Assim, este trabalho de projeto tem como objetivo conceber um modelo de BSC para aplicar no Instituto Superior de Contabilidade e Administração de Aveiro (ISCAA) de forma a sustentar a formulação, execução e avaliação da estratégia da Instituição. Inicia-se com uma revisão da literatura efetuando um enquadramento geral que apresenta os principais modelos de avaliação de desempenho, com especial destaque para o Balanced Scorecard. Neste projeto efetua-se a definição dos eixos estratégicos de atuação, perspetivas de avaliação, objetivos estratégicos e relações de causalidade entre os objetivos estratégicos associados a cada perspetiva. Conclui-se que o modelo de Balanced Scorecard concebido e descrito neste trabalho, para o ISCAA, não é um trabalho terminado, mas um ponto de partida que pretende contribuir para a definição, avaliação e controlo da estratégia da instituição.<br>In recent decades public organizations have been pressed so that their services become more transparent, accountable and closer to citizens, in order to meet their expectations and needs by providing better public services. The pressure for this change results from the economic globalization, the development of Information Technologies and Communication, and also from redefining boundaries and changing the links between the State and Society. This transformation has resulted in a growing decentralization, greater attention given to social needs resulting from the economic crisis, growing citizen’s demands towards government, bureaucracy and rationalization of public services. In this context, public managers will face major challenges to transform public administration and adjust it to become more informed and demanding. The adoption of practices, tools and models used in the private sector derives precisely from the claim of substantially improving the quality of the services provided. Performance evaluation is precisely one of these practices. This study project aims to design a model to be applied the BSC in the Instituto Superior de Contabilidade e Administração de Aveiro (ISCAA) in order to support the formulation, implementation and evaluation of the strategy of that Institution. It begins with a literature review by the main models for performance evaluation, with special emphasis on the Balanced Scorecard. We essentially focus on the definition of the strategic axes of performance, evaluation perspectives, strategic goals and causal relationships between the strategic objectives associated with each perspective. We conclude that the Balanced Scorecard model designed and described in this work for ISCAA is not a finished work, but a starting point that is intended to contribute to the definition, assessment and control strategy of the Institution.

Abstract:
A lagarta do cartucho, Spodoptera frugiperda (Smith, 1797) (Lepidoptera: Noctuidae), é uma importante praga da cultura do milho. Na região tropical, causa danos severos, podendo chegar a até 60% de redução no rendimento dos grãos. Seu controle normalmente é realizado com aplicação de inseticidas convencionais, mas o método não é recomendado devido aos inconvenientes de desequilíbrio ecológico, resistência da praga, fatores toxicológicos e econômicos. A quimioesterilização com os modernos inseticidas que atuam na fisiologia dos insetos poderá ser uma alternativa no futuro. O presente trabalho foi realizado no Departamento de Entomologia, Fitopatologia e Zoologia Agrícola da ESALQ/USP e teve como objetivo estudar o emprego de alguns inseticidas com propriedades esterilizantes sobre a fase adulta de Spodoptera frugiperda, determinando as doses que atuam sobre a reprodução dos adultos, avaliando o efeito residual da isca e testando uma isca adequada para utilização no processo de isca + produto esterilizante. Os esterilizantes foram fornecidos às mariposas via ingestão juntamente com a solução de mel a 10%. Os inseticidas utilizados foram lufenuron (Match), abamectin (Vertimec), methoxifenozide (Intrepid), teflubenzuron (Nomolt) e diflubenzuron (Dimilin). Avaliou-se a longevidade dos indivíduos, o efeito da contaminação de machos e fêmeas isoladamente, o número de posturas, o número de ovos colocados e o número de larvas eclodidas, além da preferência pela isca. O inseticida lufenuron, na dosagem de 0,75 mL/L água mostrou-se o mais eficiente na esterilização da S. frugiperda, estimulando a oviposição, mas impedindo a eclosão das lagartas. Abamectin a 0,45 mL/ L água também foi eficiente, diminuindo o número de ovos colocados e a viabilidade dos mesmo. O efeito esterilizante foi maior quando casais foram contaminados ou quando ocorreu a contaminação apenas da fêmea. O efeito residual da isca com os produtos pesquisados é de, no mínimo, 15 dias, em laboratório. Durante o período em que foram realizadas avaliações, a eficiência dos produtos sobre os parâmetros observados manteve-se constante. A longevidade dos indivíduos foi reduzida com o uso de methoxifenozide, diflubenzuron, teflubenzuron e abamectin nas dosagens de 0,45; 0,25; 0,25 e 0,45, respectivamente. A isca empregada para esterilização dos insetos via ingestão pode ser mel ou proteína de milho, indiferentemente.<br>not available

In Berlin gründeten sie eine eigene Gemeinde, die bis zur Auslöschung durch die Shoah die größte sephardische Gemeinde in Deutschland war. Trotz ihrer überschaubaren Zahl bildeten diese türkischen Sepharden keineswegs eine homogene Gruppe. Sie unterschieden sich nach Migrationszeitpunkt, sozialem Status sowie nicht zuletzt im Verhältnis zu ihrem Herkunftsland.

Despite their limited numbers, these Turkish Sephardim did not constitute a homogeneous group. They differed with respect to their year of immigration, their social situation and their relation to their country of origin. The article narrates the history of the Sephardim in Germany as a history of migration.

Abstract:
<p>By analyzing ISAR images, the characteristics of military platforms with respect to radar visibility can be evaluated. The method, which is based on the Discrete-Time Fourier Transform (DTFT), that is currently used to calculate the ISAR images requires large computations efforts. This thesis investigates the possibility to replace the DTFT with the Fast Fourier Transform (FFT). Such a replacement is not trivial since the DTFT is able to compute a contribution anywhere along the spatial axis while the FFT delivers output data at fixed sampling, which requires subsequent interpolation. The interpolation leads to a difference in the ISAR image compared to the ISAR image obtained by DTFT. On the other hand, the FFT is much faster. In this quality-and-time trade-off, the objective is to minimize the error while keeping high computational efficiency. </p><p>The FFT-approach is evaluated by studying execution time and image error when generating ISAR images for an aircraft model in a controlled environment. The FFT method shows good results. The execution speed is increased significantly without any visible differences in the ISAR images. The speed-up- factor depends on different parameters: image size, degree of zero-padding when calculating the FFT and the number of frequencies in the input data.</p>

Abstract:
Mestrado em Contabilidade - Fiscalidade<br>O conceito de ética, embora abrangente,depende de fatores, como a realidade social do indivíduo e varia com o juízo que cada um de nós tem do que está certo ou errado. Até à atualidade todas as grandes civilizações se debateram com questões desta natureza, adequadas a cada época. Hoje, as questões éticas estão relacionadas essencialmente com comportamentos não éticos no meio empresarial. O objetivo geral deste trabalho, foi perceber as perceções do comportamento ético de alguns estudantes do ISCA-UA e a influência de fatores individuais a fim de perceber a importância da ética, como diferencial positivo para o indivíduo e para a sua profissão. Desta forma, este trabalho pretende dar resposta a questões que podem ou não influenciar a tomada de decisão. Os resultados sugerem que, na escolha de qualidades pessoais, com influência na tomada de decisão ética e nos cenários descritos, particamente não se verificaram diferenças significativas entre os indivíduos, quando agrupados de acordo com os fatores individuais escolhidos. Quando analisámos a relação entre as qualidades pessoais percebidas pelos estudantes e as respectivas respostas à questão “Você teria a mesma atitude?” dos diferentes cenários, a análise por regressão logística estabeleceu correspondência com algumas das qualidades. Estes resultados sugerem que os fatores individuais têm pouca significância neste caso, mas que a importância dada a certas qualidades pessoais esta relacionada com a tomada de decisão ética.<br>The concept of ethics is comprehensive and ambiguous depending on factors, among others, the social reality of the individual and it variates with the judgment that each of us has on what is right or wrong. Up to the present all great civilizations have struggled with issues of this nature, suited to each historical period. Today, the ethical issues are mainly related to unethical behavior in business area. For this work, the main objective was to understand the perceptions of ethical behavior of students and the influence of individual factors in order to realize the importance of ethics as positive differential for the individual and their profession. Thus, this study aims to answer questions that may or may not influence decision-making. The results suggest that the choices of the personal qualities, with influence in decision-making and ethical scenarios described, virtually no differences were found between subjects when grouped according to individual factors chosen. When we looked at the relationship between personal qualities perceived by students and their responses to the question "Would you have the same attitude?" Of different scenarios, logistics regression analysis established correspondence with some of the qualities. These results suggest that the individual factors have little significance in this case, but the importance given to these personal qualities is related to ethical decision.

However, the current data warehousing technologies do not allow that the decision-making processe be carried out based on images pictorial (intrinsic) features. This analysis can not be carried out in a conventional data warehousing because it requires the management of data related to the intrinsic features of the images to perform similarity comparisons. In this work, we propose a new data warehousing environment called iCube to enable the processing of OLAP perceptual similarity queries over images, based on their pictorial (intrinsic) features. Our approach deals with and extends the three main phases of the traditional data warehousing process to allow the use of images as data. For the data integration phase, or ETL phase, we propose a process to represent the image by its intrinsic content (such as color or texture numerical descriptors) and integrate this data with conventional data in the DW. For the dimensional modeling phase, we propose a star schema, called iStar, that stores both the intrinsic and the conventional image data. Moreover, at this stage, our approach models the schema to represent and support the use of different user-defined perceptual layers. For the data analysis phase, we propose an environment in which the OLAP engine uses the image similarity as a query predicate. This environment employs a filter mechanism to speed-up the query execution. The iStar was validated through performance tests for evaluating both the building cost and the cost to process IOLAP queries. The results showed that our approach provided an impressive performance improvement in IOLAP query processing. The performance gain of the iCube over the best related work (i.e. SingleOnion) was up to 98,21%.<br>Um ambiente de data warehousing (DWing) auxilia seus usuários a tomarem decisões a partir de investigações e análises dos dados de maneira organizada e ágil. Entretanto, os atuais recursos de DWing não possibilitam que o processo de tomada de decisão seja realizado com base em comparações do conteúdo intrínseco de imagens. Esta análise não pode ser realizada por aplicações de DW convencionais porque essa utiliza, como base, imagens digitais e necessita realizar operações baseadas em similaridade, para as quais um DW convencional não oferece suporte. Neste trabalho, é proposto um ambiente de data warehouse chamado iCube que provê suporte ao processamento de consultas IOLAP (Image On-Line Analytical Processing) baseadas em diversas percepções de similaridade entre as imagens. O iCube realiza adaptações nas três principais fases de um ambiente de data warehousing convencional para permitir o uso de imagens como dados de um data warehouse (DW). Para a fase de integração, ou fase ETL (Extract, Trasnform and Load), nós propomos um processo para representar as imagens a partir de seu conteúdo intrínseco (i.e., por exemplo por meio de descritores numéricos que representam cor ou textura dessas imagens) e integrar esse conteúdo intrínseco a dados convencionais em um DW. Neste trabalho, nós também propomos um esquema estrela otimizado para o iCube, denominado iStar, que armazena tanto dados convencionais quanto dados de representação do conteúdo intrínseco das imagens. Ademais, nesta fase, o iStar foi projetado para representar e prover suporte ao uso de diferentes camadas perceptuais definidas pelo usuário. Para a fase de análise de dados, o iCube permite que processos OLAP sejam executados com o uso de comparações de similaridade como predicado de consultas e com o uso de mecanismos de filtragem para acelerar o processamento de consultas OLAP. O iCube foi validado a partir de testes de desempenho para a construção da estrutura e para o processamento de consultas IOLAP. Os resultados demonstraram que o iCube melhora significativamente o desempenho no processamento de consultas IOLAP quando comparado aos atuais recursos de IDWing. Os ganhos de desempenho do iCube contra o melhor trabalho correlato (i.e. SingleOnion) foram de até 98,21%.

Abstract:
Mestrado em Contabilidade - Fiscalidade<br>A presente dissertação tem por objetivo avaliar a perceção que os estudantes têm sobre os fatores que afetam o cumprimento fiscal, mais concretamente os fatores relacionados com a educação e o conhecimento fiscal. Deste modo, o objeto de estudo são os estudantes da licenciatura em contabilidade e da licenciatura em finanças - 1.º e 3.º ano de ambos cursos. Por sua vez, também pretendemos averiguar se esta perceção é alterada pelo nível de conhecimento fiscal ou pelo ano e/ou curso em que estes se encontram inseridos. Numa primeira fase, fizemos uma recolha de informação sobre as diversas metodologias e ações de educação fiscal realizados em alguns países, dando maior ênfase a Portugal. Posteriormente, introduzimos a problemática do cumprimento fiscal, mais concretamente o papel do conhecimento e da educação fiscal no mesmo. Através de dois inquéritos por questionário foi-nos possível recolher os dados necessários sobre a perceção dos fatores acima referidos, bem como aferir o nível de conhecimento fiscal. Após uma análise cuidada, podemos constatar que no geral a perceção sobre qualidade da divulgação fiscal, esclarecimento de dúvidas fiscais junto da Autoridade Tributária (AT), linguagem utilizada na legislação fiscal, impacte da complexidade do sistema fiscal, evasão fiscal e receita fiscal arrecadada, não se alteram consoante o ano ou o curso que o estudante se encontre inscrito, à exceção da perceção sobre o impacte negativo da legislação avulsa no conhecimento fiscal. Ao contrário do expectável, o nível de conhecimento fiscal dos estudantes de ambos os cursos mantém-se igual. Todavia, apesar de este explicar, em parte, a alteração da maioria dos fatores do cumprimento fiscal em estudo, não explica a alteração da perceção sobre a linguagem utilizada na legislação fiscal e no esclarecimento de dúvidas junto a AT.<br>This work is intended to evaluate the students’ perception of the accounting and finance degree in - 1 and 3 year of both courses – and they have on the factors affecting tax compliance, specifically the factors related to tax education and tax knowledge. On the other hand, we also want to see if this perception is altered by the level of tax knowledge or by the year and / or course in which they are inserted. At first, we collected information on the various methodologies and tax education activities carried out in some countries, placing greater emphasis on Portugal. Later, we introduced the issue of tax compliance, specifically the role of tax knowledge and tax education. Through two questionnaire surveys, it was possible to collect the necessary data on the perception of the above factors, as well as assessing the level of tax knowledge. After a careful analysis, we note that in general the perception of: the fiscal disclosure’s quality, the clarification of the tax questions before the Tax Authority (AT), the language of tax legislation, the complexity impact of the tax system, the tax evasion and collected tax revenue, do not change depending on the year or course that the student is registered, except for the perception about the negative impact of separate legislation on tax knowledge, which leads us to conclude that during the student’s academic path, he gets the necessary tools to collect all tax information contained in the tax legislation. Unlike expected, the level of tax knowledge in students of both courses keeps the same. However, although this partly explains the change of most factors of tax compliance in the study, this does not explain the change in perception about the language used in tax legislation, and to clarify doubts with the AT.

O seu hábito críptico limita os estudos sobre sua biologia e comportamento, o que dificulta um controle realmente efetivo. Uma forma de controle biorracional é a tecnologia de iscas, já que leva em consideração o comportamento social desses insetos, além de preservar o meio ambiente. Seu princípio é a transmissão de agentes químicos ou biológicos diretamente para os cupins, visando atingir toda a colônia. A isca é composta por ingredientes ativos incorporados a substratos que contenham celulose. Para que o controle seja mais eficiente, esses substratos devem ser atrativos aos cupins, estimulando o recrutamento e a atividade de alimentação dos indivíduos. Em vista do exposto, a presente pesquisa propôs, por meio de testes laboratoriais e de campo, selecionar substratos celulósicos mais atrativos e adequados à incorporação de ingredientes ativos. Inicialmente foram testados 12 tipos de substratos, e a partir desses, selecionados 4 que foram utilizados nos bioensaios posteriores. O período de duração dos testes laboratoriais foi de 28 dias. Já para os testes de campo foram executados 8 ciclos experimentais, sendo que cada ciclo durou 7 dias. Todos os resultados foram analisados estatisticamente, com nível de significância (á) igual a 0,05.

Tais fontes celulósicas...<br>The exotic species of termite Coptotermes gestroi (Family Rhinotermitidae) is considered one of the most important urban pests in Brazil. Its cryptic habit limits the studies about its biology and behavior, what difficult an effective control. A way to perform biorrational control of termites is the bait technology, since it considers the social behavior of these insects beyond preserving the environment. Its principle is the transmission of chemical or biological agents straightly for the termites, aiming to reach the whole colony. The bait is composed by active ingredients incorporated to substrates that contain cellulose. In order to improve the efficiency of the bait control, these substrates must be attractive to the termites, stimulating the recruitment and the feeding activity of the individuals. Based on the presented background, this research proposed, by means of laboratory and field tests, to select cellulosic substrates more attractive and suitable to adding the active ingredients. Initially, twelve types of substrates were tested, and four of them were selected, which had been used in the posterior bioassays. The laboratory tests were processed along 28 days, while the field tests demanded eight experimental cycles, each of them during 7 days. All the results were statistically analyzed, at a significance level (á) of 0.05. The results showed that the most attractive substrates for C. gestroi were corrugated cardboard and corn stem. Such cellulosic sources were clearly more consumed than the other materials; in addition they had recruited a large number of individuals to the baits. Some Abstract 4 factors must be considered in the matrix choice, such as their manipulation and viability to termiticid impregnation, aiming to the contribution for the development of more efficient baits in the termite control.

Bisphaerica verificando se a formação e manutenção das trilhas, o polimorfismo e o transporte de cargas são influenciados pela sazonalidade. Além disso, o presente trabalho teve como objetivo buscar um atrativo mais eficiente que a polpa cítrica para aumentar a aceitação das iscas granuladas por essa espécie de saúva. Por meio de avaliações quinzenais observou-se, durante 12 meses, o número de trilhas, o comprimento das trilhas, o número de bifurcações, a área de forrageamento, e o número de olheiros de alimentação estaqueados ativos e obstruídos. Com os resultados obtidos pôde-se concluir que o forrageamento dessa espécie sofre grande influência da sazonalidade. Durante a época seca do ano, trilhas são maiores e mais numerosas do que na chuvosa. Além disso, a partir de outubro, com a ocorrência de chuvas mais intensas, houve grande obstrução dos olheiros de alimentação, o que resultou na redução de olheiros ativos. A fi de verificar se o polimorfismo e transporte de cargas também são influenciados pela sazonalidade, coletaram-se 200 operárias com suas respectivas cargas a cada dois meses , durante um ano. Além disso, observou-se o comportamento de corte de 200 operárias. Analisando-se os resultados, verificou- se que o polimorfismo é influenciado pela sazonalidade, e que as operárias são pouco seletivas quanto ao tamanho da carga durante todo o ano. Observou-se ainda que a mesma operária que corta o material também o transporta para o ninho. Em relação à avaliação das iscas com atraentes alternativos, comparou-se o carregamento dos grânulos das iscas artesanais à base de folhas de capim Jaraguá e de cana-de-açúcar, de colmo de cana-de-açúcar, e de farinha de trigo com o da isca comercial sem princípio ativo. Também comparou-se com esta última, o carregamento da isca de papel-filtro impregnada com extrato não volátil de capim Jaraguá, metanol e isca de papel-filtro sem impregnação. Pelos resultados obtidos, conclui-se que a isca à base de capim Jaraguá foi sempre a mais preferida pelas operárias de A. bisphaerica, seguida pela isca à base de folhas de cana-de-açúcar. A isca de papel-filtro impregnada com extrato não volátil de capim Jaraguá e a isca de polpa cítrica foram pouco atrativas. As iscas granuladas comerciais inadequados para (polpa cítrica) apresentaram massa e diâmetro espécie, dificultando o seu transporte pelas operárias forrageadoras, além da baixa atratividade para essas operárias.<br>This research aimed to study the foraging activity of the grass-cutter ant Atta bisphaerica, emphasizing trail formation and maintenance as well as workers polimorphism and load transport influenced by seasonality. This investigation also had the purpose of searching for a bait attractant more efficient than citrus pulp (the attractant in commercial baits) to improve the granulated bait acceptance by this species of leaf-cutting ants. The number and the length of trails, the number of trail bifurcations, the foraging area and the number of nest entrance holes, active or not, were counted during 12 months. Results indicated that seasonality greatly affects foraging of this species. During the dry season of the year, trails are longer and more numerous than during the rainy season. Many instances of obstruction of the active nest entrance holes were found, resulting in their reduction in number along the rainy season, specially from October to March. To study the effect of the season on worker polimorphism and vegetal transportation, 200 workers were individually collected with their respective loads at two month intervals during the year. Their cutting bahavior was also observed. Results of the analyses indicated that worker polimorphism is influenced by seasonality and that they exhibit selectivity for load size during the whole year. It was also observed that the worker which cuts the grass fragment is the same individual that transports it to the nest. Retrieval of bait granules was evaluated, to compare baits manufactured in the lab with jaraguá-grass (Hyparrhenia rufa), sugar cane, white flour and the commercial baits without active ingredient. These last baits were also compared to baits made of filter- paper and impregnated with a jaraguá-grass non-volatile extract, with methanol and a blank and showed little ness attractive. Results have indicated that baits made of jaraguá-grass were always the most attractive, followed by baits of sugar cane. Commercial granulated baits had both mass and diameter inadequate for transportation by this ant species; they also show low attractiveness.

Dada a impossibilidade técnico- econômica de se coletar todos os indivíduos de um ecossistema, é necessário lançar mão de técnicas de amostragem. No caso de cupins, isto é problemático, pois os mesmos apresentam hábitos crípticos, forrageando sub- superficialmente no solo ou protegidos por túneis, o que dificulta sua localização no campo. Sendo assim, no presente trabalho, comparou-se dois métodos de amostragem, coleta manual e com iscas, com relação a rapidez na instalação, número de amostras contendo soldados, experiência prévia do amostrador e esforço para se atingir o número máximo de espécies; afim de definir, dentre os métodos testados, qual o mais viável. As iscas foram confeccionadas com esterco de bovino, por ser um material rico em celulose e de fácil obtenção. Na coleta manual, 4 amostradores foram utilizados para investigar prováveis pontos de forrageamento para cupins. Os resultados indicaram que o método de amostragem com iscas mostrou-se mais eficiente para estudos em ecologia que envolvam sub- grupos funcionais nas comunidades de cupins. O método da coleta manual foi mais indicado para levantamentos de espécies.<br>This work was carried out to outline the collection method that decrease samplings errors on the termites communities, reducing the equivocate variation on the numbers of specie collected in different places. Because of the technical and economical difficulty to collect all individuals of an ecosystem, it is necessary to use sampling methods. In the case of termites, that is problematic, because they show cryptic habits, foraging sub-superficially in the soil or protected by tunnels, what hinders its location in the field. In the present work, two sampling methods were compared, manual collection and baits collection, regarding the fastness in the installation, number of samples containing soldiers, previous experience of sampling device and effort to reach the maximum number of specie, in order to outline, among the tested methods, which is the most viable. The baits were made of bovine feces, because it is a material rich of cellulose and easy to obtain. In the manual collection, four sampling device were used to investigate the probable foraging areas of the termites. The results show that the sampling method with baits was more efficient for the ecology study that involve functional sub-groups in the termites communities. The manual collection method was the most indicate for the species surveys.<br>Não foi localizado o cpf do autor.

Abstract:
Mestrado em Contabilidade, Fiscalidade e Finanças Empresariais<br>Este projecto de investigação surgiu da consciencialização dos problemas ambientais que o mundo de hoje enfrenta. Perante este cenário, as empresas devem tomar decisões correctas quanto à relação existente entre meio ambiente e o meio empresarial. Elas necessitam de informações confiáveis e claras acerca das perdas que as suas actividades provocam no meio ambiente, identificando e descrevendo os custos e ganhos ambientais associados. Numa primeira instância, a presente investigação pretende verificar o nível de aplicação das directrizes recomendadas pelo Intergovernmental Working Group of Experts on International Standards of Accounting and Reporting (ISAR, 1998) e pelo Global Reporting Iniciative (GRI, 3° versão 2000-2007) através da evidenciação de informações sobre o meio ambiente nos relatórios anuais das dez maiores companhias brasileiras do sector de papel e celulose, no ano de 2009. O segundo objectivo é propor uma estrutura de evidenciação da informação ambiental, tendo como base as directrizes submencionadas. Tentando responder as exigências do mercado e das empresas. Conclui-se que o conjunto de directrizes com melhores práticas de divulgação de informação ambiental é o GRI, sendo que foi utilizado, parcialmente, por todas as empresas incluídas na amostra. Em concomitância, conclui-se que há um predomínio da divulgação de informações qualitativas.<br>This research project arose from the awareness of environmental problems the world faces today. Given this scenario, companies should make correct decisions regarding the relationship between environment and business environment. They need clear and reliable information about the losses that their actions cause to the environment, identifying and describing the costs and associated environmental gains. In the first instance, this research intends to investigate the level of implementation of the guidelines recommended by the Intergovernmental Working Group of Experts on International Standards of Accounting and Reporting (ISAR, 1998) and the Global Reporting Initiative (GRI, 3rd version from 2000 to 2007) by disclosure of information about the environment in the annual reports of the ten largest Brazilian companies in the pulp and paper sector in the year 2009. The second objective is to propose a framework of disclosure of environmental information, based on the undermentioned guidelines. Trying to meet market demands and business. It follows that the set of guidelines with best practices for dissemination of environmental information is the GRI, and it was used, in part, by all companies in the sample. Concurrently, we conclude that there is a predominance of the disclosure of qualitative information.

Abstract:
Mini-study project (MBA)--University of Stellenbosch, 2004.<br>ENGLISH ABSTRACT: The traditional role of the procurement functions within large organizations has changed significantly over the last couple of years. Moving away from a function purely directed at rendering a supply of material service to the relevant plants, the procurement departments are now a vital link in the chain to improve global competitiveness. In this changing role, procurement is expected to work closely with the organization's internal operations, as well as with suppliers to ensure that opportunities for gaining competitive advantages are fully explored. The procurement manager and his team will have to focus on building links to ensure that the organization's goals and objectives are met. This paper serves to describe the changes made by Iscor Steel to ensure that its procurement department is adequately equipped to manage these new challenges. The changing face of the department, its organizational structure, the operational methodology and focus are explained. The methodology of modem supply chain cost reduction initiatives undertaken by Iscor and its suppliers is explained and the results thereof are presented. The paper highlights the successes achieved by Iscor in transforming the traditional service orientated procurement function into a world class, continuous business improvement orientated department. The success revolves around changing the organizational structure in such a way as to equip the procurement function with the commercial and technical expertise to focus on specific commodities in such detail that maximum cost and efficiency advantages are realized. As an example, the latter part of the paper gives a detailed explanation of one of the tools used by the procurement department to minimize cost and maximize efficiency, and describes in general the considerable success achieved by using these tools.<br>AFRIKAANSE OPSOMMING: Die tradisionele rol van die aankopefunksie binne groot organsisasies het geweldig verander oor die laaste aantal jare. Dit het wegbeweeg van 'n funksie wat uitsluitlik gemik was op die verskaffing van materiaal aan betrokke aanlegte. Die aankope departement speel vandag 'n belangrike rol in die verbetering van 'n maatskappy se internasionale kompeteringsvermoê. In hierdie veranderende rol word van die aankopefunksie verwag om baie nou met die interne bedrywighede van die maatskappy, sowel as met die verskaffers saam te werk om te verseker dat geleenthede vir die benutting van kompeterende voordele ten volle ontgin word. Die aankopebestuurder en sy span moet fokus daarop om bande te bou wat kan verseker dat die organisasie sy doelwitte bereik. Hierdie studie ondersoek en illustreer die veranderinge wat deur Iscor Staal gemaak is om te verseker dat die aankopefunksie toegerus is om hierdie nuwe uitdagings te hanteer en te bestuur. Die veranderende funksie van die aankopedepartement, die organsisasiestruktuur, die bestuursmetodologie en die nuwe fokus word beskryf in die studie. Die metodologie van moderne kosteverminderings inisiatiewe binne die verskaffingsketting van Iscor en sy verskaffers word verduidelik en die resultate daarvan weergegee. Hierdie studie reflekteer die suksesse wat Iscor behaal het deur die verandering van die tradisionele diensgeorienteerde aankopefunksie na 'n wêreldklas aaneenlopende besigheidsverbeterings georienteerde funksie. Die sukses wentel rondom die verandering van die organisasiestruktuur op so 'n wyse dat die aankopefunksie toegerus is met kommersiële en tegniese kundigheid om te fokus op spesifieke kommoditeite sodat maksimum koste en effektiwiteitsvoordele verwesenlik word. 'n Gedeelte van die studie gee 'n gedetaileerde verduideliking van een van die metodes wat deur die aankopefunksie gebruik word om koste te verminder en effektiwiteit te verbeter en beskryf in die algemeen die sukses wat behaal is deur hierdie metodes te gebruik.

Abstract:
Dichomeris famulata Meyrick, 1914 (Lepidoptera: Gelechiidae) é uma nova praga da espiga de milho no Brasil, sendo importante em áreas de produção de sementes porque os grãos atacados pelas lagartas não germinam. O objetivo deste trabalho foi estudar a sua biologia, descrever os danos causados pela praga e verificar o efeito de alguns tratamentos no controle dos adultos, por ingestão, em condições de laboratório (25 ± 2°C, UR de 65 ± 10% e fotofase de 14 horas). Os inseticidas foram fornecidos às mariposas com e sem isca a base de mel a 10%. Os inseticidas utilizados e suas respectivas doses foram: cloridrato de cartape (0,5 g i.a. L-1 calda), metomil (0,258 g i.a. L-1 calda), acetamiprido (0,2 g i.a. L-1calda), espinosade (0,24 g i.a. L-1 calda) e pirimifós-metílico (0,5 g i.a. L-1 calda), além da testemunha. O ciclo biológico (ovoadulto) foi de 35,2 dias. O período de incubação foi de 4,1 dias. A duração média da fase larval foi de 21,1 dias, sendo observados cinco ínstares larvais. A fase pupal durou 8,6 dias para os machos e 8,1 dias para as fêmeas. O peso de pupa de machos e fêmeas foi de 12,4 e 11,3 mg, respectivamente. As fêmeas colocaram, em média, 118 ovos, apresentando um período de préoviposição de 10,7 dias e de oviposição de 14,0 dias. A longevidade média de machos e fêmeas foi de 37,02 e 44,16 dias, respectivamente, e a razão sexual de 0,48. As iscas contendo cloridrato de cartape e metomil causaram 97,92 e 83,33% de mortalidade de adultos, respectivamente 24 horas após a exposição dos tratamentos, sendo promissores no controle desta praga e podendo ser utilizados alternadamente, caso necessário. Cloridrato de cartape sem atrativo alimentar causou mortalidade de 91,67% de adultos. As lagartas danificam os estilo-estigmas e os grãos em formação ou em estado leitoso por meio de pequenos orifícios de entrada, prejudicando o endosperma e principalmente a região do embrião, inutilizando-os para sementes. A visualização dos danos é difícil, sendo que esses passam despercebidos. Os resultados obtidos neste trabalho fornecem subsídios para o estabelecimento de estratégias de manejo do inseto, especialmente em áreas de produção de sementes.<br>Dichomeris famulata Meyrick, 1914 (Lepidoptera: Gelechiidae) is a new pest of corn in Brazil, and is important in seed fields. The work goals were to study the biology of this pest, describe the damages caused by this pest and evaluate the effect of some insecticides, with and without bait, to control adults by ingestion, under laboratory conditions (25 ± 2°C, 65 ± 10% of RH and 14-hours of photophase). Pesticides were provided to moth with and without honeybee 10%. The insecticides used and respective doses were: cartap (0.5 g a.i. L-1), methomyl (0.258 g a.i. L-1), acetamiprid (0.2 g a.i. L-1), spinosad (0.24 g a.i. L-1), pirimiphos-methyl (0.5 g a.i. L-1) and a control treatment. The biological cycle (egg-adult) was 35.2 days. The incubation period was 4.1 days. The mean time larval was 21.1 days and 5 instars were observed. The pupal period was 8.6 days for male and 8.1 days for female insects. The pupae weight was 12.4 and 11.3 mg for males and females, respectively. The females laid an average of 118 eggs with a preoviposition period of 10.7 days and an oviposition time of 14.0 days. The mean longevity of males and females was 37.02 and 44.16 days, respectively, and sex ratio was 0.48. The baits with cartap and methomyl caused 97.92 and 83.33% of adults mortality, respectively, 24 hours after exposure to the treatments. This is a promising way to control this pest and it may be used in rotation. Cartap without attractive caused 91.67% of adults mortality. The caterpillars damage the silks and beginning of grain development or grains at the milk stage through little entry orifices, damaging the endosperm and, more importantly, the embryo, which disenables them for seed. Therefore, it is difficult to visualize the damage, which is unnoticed without an accurate examination. These results can support the establishment of strategies to manage this new corn ear pest, especially in seeds field.
