abstract: This research describes software based remote attestation schemes for obtaining the integrity of an executing user application and the Operating System (OS) text section of an untrusted client platform. A trusted external entity issues a challenge to the client platform. The challenge is executable code which the client must execute, and the code generates results which are sent to the external entity. These results provide the external entity an assurance as to whether the client application and the OS are in pristine condition. This work also presents a technique where it can be verified that the application which was attested, did not get replaced by a different application after completion of the attestation. The implementation of these three techniques was achieved entirely in software and is backward compatible with legacy machines on the Intel x86 architecture. This research also presents two approaches to incorporating software based "root of trust" using Virtual Machine Monitors (VMMs). The first approach determines the integrity of an executing Guest OS from the Host OS using Linux Kernel-based Virtual Machine (KVM) and qemu emulation software. The second approach implements a small VMM called MIvmm that can be utilized as a trusted codebase to build security applications such as those implemented in this research. MIvmm was conceptualized and implemented without using any existing codebase; its minimal size allows it to be trustworthy. Both the VMM approaches leverage processor support for virtualization in the Intel x86 architecture. / Dissertation/Thesis / Ph.D. Computer Science 2011

L’art de collectionner a traversé les siècles, les collections privées sont notamment à l’origine de notre patrimoine culturel. Pourtant, malgré l’importance du rôle de la collection, cette dernière reste encore un ensemble de choses mal identifié par le droit. En tant qu’ensemble de choses créé par la volonté de l’Homme, la collection n’est pas définie, et seules certaines collections sont encadrées par quelques dispositions. Par ailleurs, les collections privées sont des ensembles fragiles, elles relèvent de la propriété privée de leur collectionneur qui est libre d’en disposer comme il le souhaite. Le risque majeur de ces ensembles réside dans leur dispersion et dans l’atteinte à leur intégrité. Souvent soucieux de préserver l’intégrité et la cohérence de son ensemble, le collectionneur doit pouvoir bénéficier d’outils juridiques protecteurs adaptés à la collection. Finalement, qu’est-ce qu’une collection ? Que signifie cette notion de collection et quel(s) droit(s) peuvent s’en saisir ? Notre droit est-il en mesure de protéger efficacement une réunion de choses comme la collection privée ? En d’autres termes, la problématique consiste à répondre à la question suivante : quelle appréhension juridique pour les collections privées ? Partant, l’objectif de la thèse est de tenter de dégager une qualification juridique de la collection pour mieux adapter sa protection. En effet, la recherche se donne pour but de définir les fondements théoriques et juridiques susceptibles d’être adaptés à l’œuvre du collectionneur, pour tenter d’aboutir à un régime de protection efficace. / The art to collect crossed the centuries, the private collections are in particular at the origin of our cultural heritage. Nevertheless, in spite of the importance of the role of the collection, it still remains a set of things badly identified by the right. As together of things created by the will of the Man, the collection is not defined, and only ones certain collections are supervised by some measures.Besides, the private collections are fragile sets, they are a matter of the private property of their collector who is free to have it as he wishes it. The major risk of these sets lives in their dispersal and in the infringement on their integrity. Often worried of protecting the integrity and the coherence of his set, the collector must be able to benefit from protective legal tools adapted to the collection.Finally, what a collection? Means what this notion of collection and which right(s) can seize with it? Is our right able of protecting effectively a meeting of things as the private collection? In other words, the problem consists in answering the following question: what legal apprehension for the private collections?Therefore, the objective of the thesis is to try to identify a legal qualification of the collection to adapt better its protection. Indeed, the search gives for purpose to define the theoretical and legal foundations susceptible to be adapted to the work of the collector, to try to end in a regime of effective protection.

Syftet med denna studie är att få kunskap om förskolepersonalens förhållningssätt gentemot barns integritet i förskolan. Hur agerar och kommunicerar förskolepersonalen gentemot barnen utifrån ett integritetsperspektiv? Var går gränsen för kränkning? För att samla kunskap har observationer på tre olika förskolor och totalt sex avdelningar utförts. I studien har åtta förskollärare, sju utbildade barnskötare och fyra vikarier utan utbildning deltagit. Datan som samlats in har sedan analyserats utifrån ett barnperspektiv och relationell pedagogik för att sedan diskuteras utifrån forskning gällande barns integritet. Studien visar att det går att se en skillnad mellan hur personalen förhåller sig gentemot äldre och yngre barns integritet. Dock är det svårt att urskilja vilket förhållningssätt som är rätt eller fel, detta eftersom de barn som är inblandade i situationerna inte får uttrycka sina upplevelser eftersom studien enbart fokuserar på personalen. Studien kunde även visa att tillgång till material och/eller miljöer som skyddar barns integritet inte räcker, dessa material och miljöer måste aktivt användas och kan både påverkas negativt och positivt av förskolepersonalens förhållningssätt. Studien visar även att personalens agerande, kommunikation och bemötande gentemot barn är viktigt. Detta eftersom vuxnas förhållningssätt är något som kan komma att påverka hur barnen senare i livet kommer att förstå och förhålla sig till sin egen integritet.

The paper reflects on the importance of the general principles of public procurement in the application and interpretation of the law in this area. To this objective both the international law of administrative contracts, which has its main landmarks in the government procurement agreement of the World Trade Organization and the United Nations Model Law, as the regulation and case law of the European Union are analyzed, which has laid a very advanced teaching in this regard. Finally it is subject to review recent legislation compared to Latin America on public procurement, which attaches great importance to general principles. / En el trabajo se reflexiona acerca de la importancia de los principios generales de la contratación pública en la aplicación e interpretación del Derecho en la materia. A tal efecto se analizan tanto el Derecho Internacional de las contrataciones administrativas, que tiene sus principales hitos en el Acuerdo de compras públicas de la Organización Mundial del Comercio y en la Ley Modelo de Naciones Unidas, como la regulación y jurisprudencia de la Unión Europea, que ha sentado una doctrina muy avanzada al respecto. Finalmente es objeto de comentario la reciente legislación comparada de países de América latina sobre contratos públicos, que concede una gran importancia a los principios generales.

Uma das características mais marcantes das gerações atuais é a necessidade por armazenar e acessar cada vez mais informação em dispositivos cada vez menores. O desenvolvimento de tais equipamentos é, por si só, uma área de conhecimento incrivelmente especializada e que possui desafios que flertam a todo o instante com os limites da física. Um deles são interações entre circuitos conhecidas como interferências eletromagnéticas EMI (do inglês ElectroMagnetic Interference) e seu comportamento é estudado e combatido através de uma área conhecida como Integridade de Sinais. Neste cenário, esta dissertação tem por objetivo trazer ao leitor uma introdução ao mundo da Integridade de Sinais, desenvolvendo didaticamente modelos utilizados em cálculos de robusteza à interferência eletromagnética. É objetivo, também, apresentar e avaliar os trabalhos acadêmicos mais atuais da área, agregando valor comercial aos mesmos por aplicá-los a um projeto comercial típico e comparar com resultados experimentais. Quando da introdução à aplicação comercial que seria utilizada nos testes, expansões ao modelo de interconexões simples que se fazem necessárias em ambientes de múltiplas linhas de transmissão são expostas. Finalmente, análises de integridade de sinal foram feitas em um par diferencial de interconexões. Sua resposta foi analisada em um espectro de freqüência que variou de aproximadamente 0GHz até 10GHZ. Para efeitos de comparação, juntamente com as medidas efetuadas em uma placa prototipada e as simulações obtidas com a aplicação do modelo alvo, também foram feitos testes utilizando o ADS, uma ferramenta largamente utilizada no estudo de integridade de sinal de projetos eletrônicos. Conforme dito na análise dos resultados, é possível concluir que o modelo sob avaliação apresenta um resultado de alta confiabilidade para freqüências relativamente baixas. Conforme as freqüências ultrapassaram 4GHz, entretanto, desvios, possivelmente produzidos por pequenas variações nos valores calculados para indutâncias e capacitâncias mútuas, afetam significativamente a qualidade e veracidade do cálculo. / One of the most striking characteristics of current generations is the need for store and access more and more information and always smaller devices. The development of such equipment is a highly specialized area of knowledge and its challenges flirt with physics limits all the time. One of those challenges regards the interactions between electronic circuits known as Electromagnetic Interference (EMI). Its behavior is studied and mitigations of it are researched by an area called Signal Integrity (SI). Given this scenario, the present dissertation aims to bring the reader to the world of Signal Integrity. It accomplishes that by means of didactically present models used on EMI hardness calculations. It is also a goal to present and evaluate one of the SI’s most recent academic researches, while adding commercial value to it. The models are applied on a typical commercial design and the results are compared with measurements. Finally, expansions to the target model are presented to make capable of handle multi interconnections environments. SI analyses were performed on a differential pair. Its response was analyzed in the frequency domain from near 0GHz up to 10GHz. The measurements performed on a prototyped board, the simulation of the model, and results obtained through ADS simulations were also performed. As it is presented in results section, it is possible to conclude that the model under evaluation presents high reliability results for low frequencies. However, as frequencies become higher than 4GHz, deviations, probably caused by small variations on mutual capacitance and inductance calculations, significantly affect the quality and correctness of results.

A avaliação foi feita através de caracterização físico-química das amostras no período de oito meses de armazenagem. Para isto, amostras de gasolina, óleo diesel e álcool hidratado combustível foram acondicionadas em garrafas PET âmbar, PET incolor e em frasco de vidro, num número suficiente para que a cada mês fossem realizadas as análises de caracterização. Escolheu-se três locais para a estocagem dos combustíveis, onde acompanhou-se a temperatura e umidade diariamente: sala de armazenagem, com temperaturas máximas na faixa 27,3-32,8 oC; laboratório (LAB), com temperaturas máximas na faixa 24,5-29,6 oC; e refrigerador, com temperaturas máximas na faixa 6,8-12,8 oC. As análises realizadas para as amostras de gasolina foram: aspecto, destilação, massa específica, teor de benzeno e teor de álcool anidro. Para as amostras de álcool, realizaram-se as seguintes análises: pH, condutividade, massa específica e teor alcoólico; enquanto que para as amostras de óleo diesel, acompanhou-se o aspecto, massa específica, destilação, teor de enxofre e ponto de fulgor. No momento da preparação das amostras, foram tiradas alíquotas de cada combustível e realizados os ensaios e análises do ponto inicial, mês zero. A partir daí, repetiu-se determinações mensalmente, até o oitavo mês, utilizando-se de métodos analíticos oficiais e validados para acompanhar o comportamento de cada parâmetro. Com os resultados obtidos, verificou-se que tanto os frascos de vidro como as garrafas PET podem ser utilizadas como embalagens para os combustíveis, principalmente para gasolina e diesel, para períodos longos, mesmo em locais de temperatura mais alta ou mais baixa, apenas com algumas considerações quanto a massa específica para o diesel nas garrafas PET, onde observou-se um acréscimo de cerca de 0,0010 g/cm3, com uma incerteza de medição de 0,0005 g/cm3 . Contudo, observaram-se restrições quanto ao uso das garrafas PET para o armazenamento do álcool, principalmente com relação ao pH, onde observou-se um decréscimo de cerca de 2 unidades, com incerteza de medição de 0,06 pH, e teor alcoólico (massa específica), onde observou-se um acréscimo de cerca de 0,0015 g/cm3, com uma incerteza de medição de 0,0006 g/cm3. O frasco de vidro se apresentou mais adequado para o armazenamento de álcool. / This work evaluates the influences of moisture, temperature and type of the bottles in the fuel samples integrity, during the time of storage (8 months), through the physical- chemistry analysis. Samples of gasoline, diesel oil and alcohol were prepared, and the bottles (amber PET, colourless PET, and amber glass) had been filled with respective fuels, in amount enough, considering to each month (duplicate) and to each place (three).These bottles were placed in three different places, where was noted dayly the temperature and humidity: in the storage room, where the maxims temperatures varied by 27,3-32,8 oC; in the laboratory, where the maxims temperatures varied by 24,5-29,6 oC; and in the refrigerator, where the maxims temperatures varied by 6,8-12,8 oC. The analysis for gasoline samples was: aspect, destilation, especific mass, benzene content and alcohol content. For alcohol samples, the analysis was: pH, condutivity, especific mass and alcohol content. For diesel oil samples, was: aspect, especific mass, destilation, sulfur content and flash point. The initial samples were withdrawed, as the zero point, before to fill the bottles, of each fuel, and maked the official phisycal-chemistry analysis. Monthly, until the eighth month, these analysis had been done, of the each bottle to each fuel, to each place, to monitor the behaviour of each analytical parameter. In agreement with the analytical results, both the glass and PET botlles had good performance as preservactive bottles and they can be used as recipient for the fuels to long time, mainly for gasoline and diesel oil, even in place with high or down temperatures, with some considerations for the PET bottles about the especific mass to diesel oil, where was observed an increase of 0,0010 g/cm3 with an uncertainty of 0,0005 g/cm3. However, was observed restrictions to use PET bottles to storage alcohol, mainly to pH, where was detected a reduction of 2 unities of pH, with an uncertainty of 0,06 pH, and to alcoholic content (especific mass) parameters, where was detected an increase of 0,0015 g/cm3, with an uncertainty of 0,0006 g/cm3. The glass bottle presented itself the best bottle to storage alcohol.

Reafirma-se o direito à saúde das pessoas com deficiência, onde a reabilitação é convidada a contribuir para a participação plena das pessoas com deficiência. No Sistema Único de Saúde Brasileiro (SUS), a reabilitação de pessoas com deficiência física segue um modelo de rede de serviços hierarquizados em diferentes níveis de complexidade. Este estudo tem como objetivos levantar características do modelo de reabilitação física num serviço de referência do SUS e analisar a incorporação do princípio doutrinário da integralidade na atenção à saúde. Realizou-se um estudo de caso com dados secundários de pesquisa sobre a rede de assistência a pessoas com deficiência física na região nordeste do Brasil. A análise de conteúdo dos grupos focais, entrevista semi-estruturada e documentos institucionais foram antecedidos por análise de documentos que sustentam as práticas de reabilitação normativa e conceitualmente. Os resultados apontam para um modelo de reabilitação que supera a concepção tradicional de saúde e de deficiência, mas enfrenta desafios quanto à articulação com o conjunto da atenção à saúde e com a efetivação dos resultados esperados da reabilitação. / Salvador

Le développement du marché des appareils de communication nomades, a nécessité l'intégration de composants passifs et actifs sur du silicium via des montages « hybrides ».Ceci a amené le LMP partenaire de l'entreprise STMicroelectronics à rechercher des solutions pour une intégration « monolithique ». Le silicium micro/mésoporeux est un candidat potentiel pour satisfaire les exigences de cette intégration. Ce travail traite de la réalisation de caissons profonds de silicium poreux sur silicium résistif de type P 30-50 Ω.cm et N 37-46Ω.cm. L'utilisation de l'acide acétique comme solvant industriellement compatible nous a permis de réaliser des structures micro/mésoporeuses. L'intégrité mécanique de nos échantillons a été étudiée via la mesure de la porosité en fonction de l'épaisseur. Ainsi des caissons poreux avec des épaisseurs de plus de 400 µm et 50 % de porosité ont été fabriqués.La réalisation d'une couche N⁺ sur du silicium type N 37-46 Ω.cm a permis la mise en œuvre de doubles couches composées d'une dizaine de micromètres de micro/mésoporeuse sur une couche de 200 µ.m de silicium macroporeux. Des changements importants ont été observés par addition d'une très faible quantité d'un tensioactif (triton X-I00®) a notre solution électrolytique et où des doubles couches ont été obtenues sur silicium type P 30-50 Ω.cm. / The rapid expansion of wireless devices caused a tremendous demand of the development of active and passive devices integration on silicon via « hybrid » systems. The search of a« monolithic » integration has led the LMP in partnership with STMicroelectronics to focus on this topic. Micro/Mesoporous silicon is a good candidate to fulfill the requirements to achieve this purpose. The present work deals with the realization of thick porous silicon layers on low doped P type (30-50 Ω.cm) and N type Si (37-46 Ω.cm). The use of a particular solution based on HF-H₂O and acetic acid allowed the implementation of micro/mesoporous Si structures. The mechanical integrity is studied via the porosity and the PS layer thickness.Thus layers with a thickness up to 400 µm have been implemented with a porosity of 50 % on P Type Si samples. Double layers with micro/mesoporous layer of tenth micrometers on a macroporous layer stack up to 200 µm have been realized on N-Type Si samples via the realization of an N⁺ layer by phosphorous implantation. Important changes occurred when a tiny amount of surfactant (triton X-I00®) has been introduced into our organic electrolyte and allowed the implementation of double layers on P type Si.

The purpose of the study was to evaluate if a novel approach to the didactic component of Behavior Skills Training (BST) would have an effect on parent treatment integrity responding to child problem behavior. During baseline, the researcher observed parent responses to child problem behavior across brief intervals. Additionally, a foundational ABA concepts didactic session took place with the researcher. In the second phase, parents participated in didactic learning sessions to learn about functions of behavior, as well as the appropriate function-based responses to their child’s problem behavior outlined in his/her Behavior Intervention Plan. During the BST phase, the researcher modeled function-based responding and/or provided performance feedback to parents on their correct or incorrect responses to child problem behavior. Results showed that the novel approach to the didactic component in BST was effective at increasing parent correct responding to child problem behavior for 2 out of 3 families.

Additional outcome measures included teachers' self-efficacy and teachers' perceptions of social validity of the Strong Kids program. Participants included six teachers, three of whom were randomly assigned to the treatment group and three of whom were randomly assigned to the control group. Teachers in the treatment group received brief performance feedback consultation for six out of the twelve Strong Kids lessons; whereas, teachers in the control group did not receive consultation, but instead were given a frequently asked questions sheet that provided them with general information about the curriculum. Results of the study indicated an increase in implementation fidelity for the teachers receiving performance feedback consultation and a decrease in implementation fidelity for the teachers who did not receive performance feedback. The data did not indicate any substantial effects for the consultation group teachers with respect to quality of implementation or student responsiveness. Overall, teachers in both the treatment and control groups had positive attitudes toward social-emotional learning and the curriculum. Both groups of teachers also reported similar negative attitudes regarding the curriculum. For example, both groups of teachers felt that the lessons took too long to implement within a given class period. Implications of this study for future research and practice are discussed. / Committee in charge: Kenneth Merrell, Chairperson, Special Education and Clinical Sciences; Jeffrey Sprague, Member, Special Education and Clinical Sciences; Terry Scott, Member, Special Education and Clinical Sciences; John Seeley, Member, Not from U of 0; Lynn Kahle, Outside Member, Marketing
