The human immunodeficiency virus preventive vaccine research at the French National Agency for acquired immunodeficiency syndrome research

The human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) epidemic is of unprecedented gravity and is spreading rapidly, notably in the most disadvantaged regions of the world. The search for a preventive vaccine is thus an absolute priority. For over 10 years the French National Agency for AIDS research (ANRS) has been committed to an original program combining basic science and clinical research. The HIV preventive vaccine research program run by the ANRS covers upstream research for the definition of immunogens, animal models, and clinical research to evaluate candidate vaccines. Most researchers in 2004 believe that it should be possible to obtain partial vaccine protection through the induction of a strong and multiepitopic cellular response. Since 1992, the ANRS has set up 15 phases I and II clinical trials in order to evaluate the safety and the capacity of the candidate vaccines for inducing cellular immune responses. The tested candidate vaccines were increasingly complex recombinant canarypox viruses (Alvac) containing sequences coding for certain viral proteins, utilized alone or combined with other immunogens (whole or truncated envelope proteins). ANRS has also been developing an original strategy based on the utilization of lipopeptides. These comprise synthetic fragments of viral proteins associated with lipids that facilitate the induction of a cellular immune response. These approaches promptly allowed the assessment of a prime-boost strategy combining a viral vector and lipopeptides.

Assessment of statistical iterative reconstructions to optimize CT examination protocols for children and young adults

La tomodensitométrie (CT) est une technique d'imagerie dont l'intérêt n'a cessé de croître depuis son apparition dans le début des années 70. Dans le domaine médical, son utilisation est incontournable à tel point que ce système d'imagerie pourrait être amené à devenir victime de son succès si son impact au niveau de l'exposition de la population ne fait pas l'objet d'une attention particulière. Bien évidemment, l'augmentation du nombre d'examens CT a permis d'améliorer la prise en charge des patients ou a rendu certaines procédures moins invasives. Toutefois, pour assurer que le compromis risque - bénéfice soit toujours en faveur du patient, il est nécessaire d'éviter de délivrer des doses non utiles au diagnostic.¦Si cette action est importante chez l'adulte elle doit être une priorité lorsque les examens se font chez l'enfant, en particulier lorsque l'on suit des pathologies qui nécessitent plusieurs examens CT au cours de la vie du patient. En effet, les enfants et jeunes adultes sont plus radiosensibles. De plus, leur espérance de vie étant supérieure à celle de l'adulte, ils présentent un risque accru de développer un cancer radio-induit dont la phase de latence peut être supérieure à vingt ans. Partant du principe que chaque examen radiologique est justifié, il devient dès lors nécessaire d'optimiser les protocoles d'acquisitions pour s'assurer que le patient ne soit pas irradié inutilement. L'avancée technologique au niveau du CT est très rapide et depuis 2009, de nouvelles techniques de reconstructions d'images, dites itératives, ont été introduites afin de réduire la dose et améliorer la qualité d'image.¦Le présent travail a pour objectif de déterminer le potentiel des reconstructions itératives statistiques pour réduire au minimum les doses délivrées lors d'examens CT chez l'enfant et le jeune adulte tout en conservant une qualité d'image permettant le diagnostic, ceci afin de proposer des protocoles optimisés.¦L'optimisation d'un protocole d'examen CT nécessite de pouvoir évaluer la dose délivrée et la qualité d'image utile au diagnostic. Alors que la dose est estimée au moyen d'indices CT (CTDIV0| et DLP), ce travail a la particularité d'utiliser deux approches radicalement différentes pour évaluer la qualité d'image. La première approche dite « physique », se base sur le calcul de métriques physiques (SD, MTF, NPS, etc.) mesurées dans des conditions bien définies, le plus souvent sur fantômes. Bien que cette démarche soit limitée car elle n'intègre pas la perception des radiologues, elle permet de caractériser de manière rapide et simple certaines propriétés d'une image. La seconde approche, dite « clinique », est basée sur l'évaluation de structures anatomiques (critères diagnostiques) présentes sur les images de patients. Des radiologues, impliqués dans l'étape d'évaluation, doivent qualifier la qualité des structures d'un point de vue diagnostique en utilisant une échelle de notation simple. Cette approche, lourde à mettre en place, a l'avantage d'être proche du travail du radiologue et peut être considérée comme méthode de référence.¦Parmi les principaux résultats de ce travail, il a été montré que les algorithmes itératifs statistiques étudiés en clinique (ASIR?, VEO?) ont un important potentiel pour réduire la dose au CT (jusqu'à-90%). Cependant, par leur fonctionnement, ils modifient l'apparence de l'image en entraînant un changement de texture qui pourrait affecter la qualité du diagnostic. En comparant les résultats fournis par les approches « clinique » et « physique », il a été montré que ce changement de texture se traduit par une modification du spectre fréquentiel du bruit dont l'analyse permet d'anticiper ou d'éviter une perte diagnostique. Ce travail montre également que l'intégration de ces nouvelles techniques de reconstruction en clinique ne peut se faire de manière simple sur la base de protocoles utilisant des reconstructions classiques. Les conclusions de ce travail ainsi que les outils développés pourront également guider de futures études dans le domaine de la qualité d'image, comme par exemple, l'analyse de textures ou la modélisation d'observateurs pour le CT.¦-¦Computed tomography (CT) is an imaging technique in which interest has been growing since it first began to be used in the early 1970s. In the clinical environment, this imaging system has emerged as the gold standard modality because of its high sensitivity in producing accurate diagnostic images. However, even if a direct benefit to patient healthcare is attributed to CT, the dramatic increase of the number of CT examinations performed has raised concerns about the potential negative effects of ionizing radiation on the population. To insure a benefit - risk that works in favor of a patient, it is important to balance image quality and dose in order to avoid unnecessary patient exposure.¦If this balance is important for adults, it should be an absolute priority for children undergoing CT examinations, especially for patients suffering from diseases requiring several follow-up examinations over the patient's lifetime. Indeed, children and young adults are more sensitive to ionizing radiation and have an extended life span in comparison to adults. For this population, the risk of developing cancer, whose latency period exceeds 20 years, is significantly higher than for adults. Assuming that each patient examination is justified, it then becomes a priority to optimize CT acquisition protocols in order to minimize the delivered dose to the patient. Over the past few years, CT advances have been developing at a rapid pace. Since 2009, new iterative image reconstruction techniques, called statistical iterative reconstructions, have been introduced in order to decrease patient exposure and improve image quality.¦The goal of the present work was to determine the potential of statistical iterative reconstructions to reduce dose as much as possible without compromising image quality and maintain diagnosis of children and young adult examinations.¦The optimization step requires the evaluation of the delivered dose and image quality useful to perform diagnosis. While the dose is estimated using CT indices (CTDIV0| and DLP), the particularity of this research was to use two radically different approaches to evaluate image quality. The first approach, called the "physical approach", computed physical metrics (SD, MTF, NPS, etc.) measured on phantoms in well-known conditions. Although this technique has some limitations because it does not take radiologist perspective into account, it enables the physical characterization of image properties in a simple and timely way. The second approach, called the "clinical approach", was based on the evaluation of anatomical structures (diagnostic criteria) present on patient images. Radiologists, involved in the assessment step, were asked to score image quality of structures for diagnostic purposes using a simple rating scale. This approach is relatively complicated to implement and also time-consuming. Nevertheless, it has the advantage of being very close to the practice of radiologists and is considered as a reference method.¦Primarily, this work revealed that the statistical iterative reconstructions studied in clinic (ASIR? and VECO have a strong potential to reduce CT dose (up to -90%). However, by their mechanisms, they lead to a modification of the image appearance with a change in image texture which may then effect the quality of the diagnosis. By comparing the results of the "clinical" and "physical" approach, it was showed that a change in texture is related to a modification of the noise spectrum bandwidth. The NPS analysis makes possible to anticipate or avoid a decrease in image quality. This project demonstrated that integrating these new statistical iterative reconstruction techniques can be complex and cannot be made on the basis of protocols using conventional reconstructions. The conclusions of this work and the image quality tools developed will be able to guide future studies in the field of image quality as texture analysis or model observers dedicated to CT.

Five essays on bankruptcy

Chapter 2 Bankruptcy Initiation In The New Era of Chapter 11 2.1 Abstract The bankruptcy act of 1978 placed corporate managers (as debtor in possession) in control of the bankruptcy process. Between 2000 and 2001 managers apparently lost this control to secured creditors. This study examines financial ratios of firms filing for bankruptcy between 1993 and 2004 and tests the hypothesis that the change from manager to creditor control created or exacerbated the managerial (and dominant creditor) incentive to delay bankruptcy filing. We find a clear deterioration in the financial conditions of firms filing after 2001. This is consistent with managers (or creditors who control them) delaying filing for bankruptcy. We also observe patterns of operating losses and liquidations that suggest adverse economic consequences from such delay. Chapter 3 Bankruptcy Resolution: Priority of Claims with the Secured Creditor in Control 3.1 Abstract We present new evidence on the violation of priority of claims in bankruptcy using a sample of 222 firms that tiled for Chapter 11 bankruptcy over the 1993-2004 period. Our study reveals a dramatic reduction in the violations of priority of claims compared to research on prior periods. These results are consistent with changes in both court practices and laws transferring power to the secured creditors over our sample period. We also find an increase in the time from the date of a bankruptcy filing to reaching plan confirmation where priority is not violated. Chapter 4 Bankruptcy Resolution: Speed, APR Violations and Delaware 4.1 Abstract We analyze speed of bankruptcy resolution on a sample of 294 US firms filing for bankruptcy in the 1993-2004 period. We find strong association between type of Chapter II filing and speed of bankruptcy resolution. We also find that violations to the absolute priority rule reduce the time from bankruptcy filing to plan confirmation. This is consistent with the hypothesis that creditors are willing to grant concessions in exchange for faster bankruptcy resolution. Furthermore, after controlling for the type of filing and violations to the absolute priority rule, we do not find any difference in the duration of the bankruptcy process for firms filing in Delaware, New York, or other bankruptcy districts. Chapter 5 Financial Distress and Corporate Control 5.1 Abstract We examine the replacement rates of directors and executives in 63 firms filing for bank ruptcy during the 1995-2002 period. We find that over 76% of directors and executives are replaced in the four year period from the year prior to the bankruptcy filing through three years after. These rates are higher than those found in prior research and is consistent with changes in bankruptcy procedures and practice (i.e. the increased secured creditors control over the process due to both DIP financing and changes in the Uniform Commercial Code) having a significant impact on the corporate governance of firms in financial distress. Chapter 6 Financial Statement Restatements: Decision to File for Bankruptcy 6.1 Abstract On a sample of 201 firms that restated their financial statements we analyze the process of regaining investor trust in a two year period after the restatement. We find that 20% of firms that restate their financial statements tile for bankruptcy or restructure out of court. Our results also indicate that the decisions to change auditor or management is correlated with a higher probability of failure. Increased media attention appears to partly explain the decision of firms to restructure their debt or tile for bankruptcy.

Three essays in dynamic corporate finance

The three essays constituting this thesis focus on financing and cash management policy. The first essay aims to shed light on why firms issue debt so conservatively. In particular, it examines the effects of shareholder and creditor protection on capital structure choices. It starts by building a contingent claims model where financing policy results from a trade-off between tax benefits, contracting costs and agency costs. In this setup, controlling shareholders can divert part of the firms' cash ows as private benefits at the expense of minority share- holders. In addition, shareholders as a class can behave strategically at the time of default leading to deviations from the absolute priority rule. The analysis demonstrates that investor protection is a first order determinant of firms' financing choices and that conflicts of interests between firm claimholders may help explain the level and cross-sectional variation of observed leverage ratios. The second essay focuses on the practical relevance of agency conflicts. De- spite the theoretical development of the literature on agency conflicts and firm policy choices, the magnitude of manager-shareholder conflicts is still an open question. This essay proposes a methodology for quantifying these agency conflicts. To do so, it examines the impact of managerial entrenchment on corporate financing decisions. It builds a dynamic contingent claims model in which managers do not act in the best interest of shareholders, but rather pursue private benefits at the expense of shareholders. Managers have discretion over financing and dividend policies. However, shareholders can remove the manager at a cost. The analysis demonstrates that entrenched managers restructure less frequently and issue less debt than optimal for shareholders. I take the model to the data and use observed financing choices to provide firm-specific estimates of the degree of managerial entrenchment. Using structural econometrics, I find costs of control challenges of 2-7% on average (.8-5% at median). The estimates of the agency costs vary with variables that one expects to determine managerial incentives. In addition, these costs are sufficient to resolve the low- and zero-leverage puzzles and explain the time series of observed leverage ratios. Finally, the analysis shows that governance mechanisms significantly affect the value of control and firms' financing decisions. The third essay is concerned with the documented time trend in corporate cash holdings by Bates, Kahle and Stulz (BKS,2003). BKS find that firms' cash holdings double from 10% to 20% over the 1980 to 2005 period. This essay provides an explanation of this phenomenon by examining the effects of product market competition on firms' cash holdings in the presence of financial constraints. It develops a real options model in which cash holdings may be used to cover unexpected operating losses and avoid inefficient closure. The model generates new predictions relating cash holdings to firm and industry characteristics such as the intensity of competition, cash flow volatility, or financing constraints. The empirical examination of the model shows strong support of model's predictions. In addition, it shows that the time trend in cash holdings documented by BKS can be at least partly attributed to a competition effect.

A prioridade absoluta na Constituição Federal de 1988: cognição do art. 227 como princípio-garantia dos direitos fundamentais da criança e do adolescente

The study undertakes the analysis of the constitutional warranty principle of the Absolute Priority of the children and adolescents fundamental rights concerning to the sense, reach, content, addressees and effectiveness. Then, we begin with the study of the Constitution, text where is inserted the principle on examination, opportunity on which it verifies the concept and conceptions of the Constitution, theories, functions, it normative power and the constitutional feeling. Soon after, the fundamental rights theory is analyzed, focusing your origin, importance, functions, protection, restrictions, duties, characteristics and effectiveness. Then, it is led in general to the place of the principles, moment that leans to their concept, evolution, functions, classification and characteristics. Finally, it is appreciated the principle of the Absolute Priority approaching to the meaning and reach, the normative force and importance, historical precedents, materialize rules, addressees and its normative power and enforcement

Ativismo judicial e materialização das políticas públicas infanto-juvenis na constituição da república: Fixação de planos ideais de atuação para os atores do Sistema de Garantia de Direitos (SGD)

The research arose from the necessity of showing ways to be followed by the actors of the System Guaranteeing Rights of the Child and Adolescent (SGD), regarding the implementation of rights for young people, because the legislation in force in Brazil is currently considered a model around the world and, paradoxically, the fundamental rights of children and adolescents are not met, even with the constitutionally guaranteed priority. Thus, the study investigates the fundamentality rights for young people, enshrined in the Constitution of the Republic, as well as the ways of effectiveness of these rights through the actions of actors of the System Guaranteeing Rights, especially the judiciary. Focusing realized, studying theories of fundamental rights, especially Structuring a Theory of Law (Strukturiende Rechtslehre), Friedrich Müller, who emphasizes the need for analysis of social reality in the application of the rule of law. Study also the public budget and public policies concerning children and adolescents, with emphasis on preparation of budget laws and the process of discussion, deliberation, choice and implementation of public policies for children and teenagers. It then presents the typical functions of the members of System Guaranteeing Rights, as well as prepare a plan for optimum performance for each of the actors, with emphasis on analysis of the implementation of public policies at the municipal level. Finally, it analyzes the theory of separation of three powers, and discusses the positive and negative factors for judicial intervention, concluding that the Courts can consider the action activist, from finding the omission of the Executive and legislative branches, as regards the implementation of the rights of children and adolescents, as well as the rights of children and young people are not realized in most cases, due to the omission of actors of the System Guaranteeing Rights

Violência doméstica contra crianças e adolescentes: da denúncia ao atendimento

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)

Educação e políticas públicas para o idoso

The ‘Estatuto do Idoso’ (senior citizen statute), Brazilian federal law promulgated in 2003, defines senior citizen as the person with 60 years old, or more. Revered as a landmark recognition of the senior´s rights, it guarantees, among others, the right of education. According to the statutory provisions, the education is personal right of the elderly person and must be assured with absolute priority by the State, the family, the society, as well by entities. However, in practice, just few senior citizens enjoy the right of education, since this policy has not been developed with focus in the old age, since educational practices are aimed, in most cases, to the younger age groups. Nevertheless, some initiatives seek to invest in the education for the elderly, like happens with the University of the Third Age (U3A). Although this kind of initiatives have been reason of celebration such projects should be enforced and consolidated as an object of better political investment to enlarge the access to the education right to the senior citizens in general. Due to the visibility achieved by the senior population, a possible way to the establishment of services in the area of education, would be the formation of partnerships between educational institutions that understand old age as a potential expansion of cultural goods and production of knowledge.

Judiciary as the last resort to protect children and adolescents: intersectoral actions, investment in human resources, and structuring of services

This study aimed to identify the work developed by the Judiciary to prevent sexual violence against children and adolescents within the family. The approach to social representations in a cultural perspective was used. The field study consisted in the 1st and 2nd Court of Crimes against Children and Adolescents, at the State Supreme Court of Pernambuco, Brazil. Participant observation, semi-structured interviews, and focus group with 17 subjects were the techniques for data collection, analyzed through the interpretation of meanings, allowing the identification of the category "The Judiciary as the ultimate level" and the following subcategories: "The public policies to prevent violence" and "The structure and dynamics of Courts". This study allows the visualization of the Judiciary's limitations with regard to the full protection and absolute priority, and that the work along with the victims demands investments in structure and human resources.

El vidrio y la luz en la envolvente contemporánea

Los arquitectos se han sentido progresivamente inclinados a incorporar superficies de vidrio cada vez mayores en sus proyectos de arquitectura, en correspondencia con una percepción socio-cultural del vidrio vinculada al progreso, la contemporaneidad y el bienestar, así como por la versatilidad de este material para expresar aspectos de la identidad del proyecto, establecer comunicación con el entorno y actuar como un escaparate para las tecnologías emergentes. A pesar de esta receptividad para acoger los sistemas tecnológicos más avanzados, la envolvente de vidrio contemporánea muy raramente integra tecnología avanzada para el control de la luz natural. Desde la arquitectura, el proyecto de la luz natural a través de la superficie de vidrio se ha explorado muy escasamente, aún cuando en las últimas tres décadas se haya producido una gran diversidad de soluciones tecnológicas para este propósito. Uno de los motivos principales para esta falta de sinergia es la inconsistencia conceptual que impulsa a los procesos proyectuales de la arquitectura y a los desarrollos tecnológicos para la sostenibilidad. Por un lado, las especificaciones de las tecnologías del control de la luz natural se determinan fundamentalmente desde una perspectiva científica de la eficiencia, que no tiene en consideración otros intereses y preocupaciones arquitectónicos. Por otro lado, la práctica arquitectónica no ha asimilado un pensamiento técnico en torno a la luz natural que lo determine como un agente clave del proceso proyectual, incluso cuando la sostenibilidad se perfile como la fuerza que ha de liderar la arquitectura del futuro y, en este sentido, sea una prioridad absoluta minimizar las consecuencias económicas y ecológicas del impacto negativo del vidrio. Por medio del escrutinio de valores culturales, proyectuales, funcionales y ecológicos, esta tesis aborda el estudio del precario diálogo transdisciplinar entre la evolución de la envolvente de vidrio en la arquitectura contemporánea y el desarrollo de soluciones tecnológicas para el proyecto de la luz natural, e identifica sus principales puntos de divergencia como los temas centrales desde los que proyectar con vidrio en una arquitectura sostenible futura. Desde una perspectiva energética, este ejercicio es un paso crítico para concienciar sobre la gravedad de la situación presente y establecer los cimientos para líneas de intervención esenciales para hacer a ambos mundos converger. Desde la óptica arquitectónica, este estudio representa además de una oportunidad para entender los potenciales proyectuales de estas tecnologías y reflexionar sobre la relación vidrio-luz, un escenario desde el que comprender el estatus incongruente de la sostenibilidad tecnológica en la arquitectura actual, contribuyendo a que se genere una contextualización recíproca entre la investigación en energía y la práctica de la arquitectura futura. ABSTRACT Architects are increasingly demanded to incorporate extensive glazed areas in buildings in correspondence with a socio-cultural perception of glass linked with progress, contemporaneity and welfare, as well as for this material’s versatility to express identity features, establish communication with its environment, and perform as a showroom for emergent technologies. Despite this disposition to take cutting-edge technology in, the contemporary glass envelope very scarcely integrates advanced daylight control technology. From an architectural standpoint, the exploration of the manipulation of natural light through the glass surface has been very swallow, even though a wide range of technical solutions has being produced in the last three decades for this purpose. One of the core issues behind this inconsistency is the lack of established synergy between architectural design processes and sustainable technological developments. From one side, the specifications of daylighting technologies are primarily determined by a scientific perspective of efficiency and disregard fundamental architectural concerns and interests. From another, architectural practice does not conceive sustainable technologies as key active agents in the design process, despite the fact the concept of sustainability is constantly regarded as the driving force of the leading-edge architecture of the future, and in this sense, it becomes an absolute priority to minimize the ecological and economical consequences of glass decisive impact in buildings. Through the scrutiny of cultural, functional and ecological values, this thesis analyses the precarious transdisciplinary dialogue between the evolution of the glass envelope in contemporary architecture and the development of daylighting technological solutions, and identifies the core affairs necessary to a sustainable integration of glass facades into future architecture. From an energy point of view, this exercise is a critical step to raise awareness about the severity of the present situation, and to establish the underpinnings for new lines of intervention essential to make both worlds efficiently converge. Architecturally speaking, in addition to the opportunity to understand the design potentials of these technologies and reflect on the relationship glasslight, this study contributes with a scenario from which generate the reciprocal contextualization of energy building research to future architectural practices.

Validación de sistemas constructivos de los cerramientos de la edificación mediante la aplicación de los métodos de decisión multicriterio : aplicación al catálogo de elementos constructivos del Código Técnico de la Edificación

Como punto de partida para el desarrollo de la Tesis, se mantiene la hipótesis de que es posible establecer métodos de evaluación global sobre el grado de utilidad de los sistemas constructivos correspondientes a los cerramientos de la edificación. Tales métodos habrían de posibilitar, de entre una serie finita de sistemas alternativos, cuáles de ellos son los objetivamente más adecuados para su selección en un entorno de decisión concreto, y habrían de permitir fundamentar la justificación objetiva de tal decisión. Paralelamente a esta hipótesis de carácter general, se planteó desde el inicio la necesidad de comprobación de una hipótesis de partida particular según la cual los sistemas constructivos basados en la utilización de componentes prefabricados, o procesos de puesta en obra con un alto grado de industrialización arrojarían valores de utilidad mayores que los sistemas tradicionales basados en la albañilería. Para la verificación de estas dos hipótesis de partida se ha procedido inicialmente a la selección de un conjunto coherente de doce sistemas de cerramientos de la edificación que pudiese servir como testigo de su diversidad potencial, para proceder a su valoración comparativa. El método de valoración propuesto ha entrado a considerar una serie de factores de diversa índole que no son reducibles a un único parámetro o magnitud que permitiese una valoración de tipo lineal sobre su idoneidad relativa, ni que permitiese establecer un grado de prelación entre los distintos sistemas constructivos alternativos de manera absoluta. Para resolver este tour de force o desafío metodológico se ha acudido a la aplicación de metodologías de valoración que nos permitiesen establecer de forma racional dicha comparativa. Nos referimos a una serie de metodologías provenientes en primera instancia de las ciencias exactas, que reciben la denominación de métodos de ayuda a la decisión multicriterio, y en concreto el denominado método ELECTRE. Inicialmente, se ha planteado la aplicación del método de análisis sobre doce sistemas constructivos seleccionados de tal forma que representasen de forma adecuada las tres categorías establecidas para caracterizar la totalidad de sistemas constructivos posibles; por peso, grado de prefabricación y grado de ventilación. Si bien la combinación de las tres categorías básicas anteriormente señaladas produce un total de 18 subcategorías conceptuales, tomamos finalmente doce subcategorías dado que consideramos que es un número operativo suficiente por extenso para el análisis propuesto y elimina tipos no relevantes. Aplicado el método propuesto, a estos doce sistemas constructivos “testigo”, se constata el mayor grado de utilidad de los sistemas prefabricados, pesados y no ventilados. Al hilo del análisis realizado en la Parte II de la Tesis sobre los doce sistemas constructivos “testigo”, se ha realizado un volcado de los sistemas constructivos incluidos en el Catalogo de Elementos Constructivos del CTE (versión 2010) sobre las dieciocho subcategorías definidas en dicha Parte II para caracterizar los sistemas constructivos “testigo”. Posteriormente, se ha procedido a una parametrización de la totalidad de sistemas constructivos para cerramientos de fachadas incluidos en este Catálogo. La parametrización sistemática realizada ha permitido establecer, mediante el cálculo del valor medio que adoptan los parámetros de los sistemas pertenecientes a una misma familia de las establecidas por el Catálogo, una caracterización comparativa del grado de utilidad de dichas familias, tanto en lo relativo a cada uno de los parámetros como en una valoración global de sus valores, de carácter indicativo. Una vez realizada una parametrización completa de la totalidad de sistemas constructivos incluidos en el Catálogo, se ha realizado una simulación de aplicación de la metodología de validación desarrollada en la Parte II de la presente Tesis, con el objeto de comprobar su adecuación al caso. En conclusión, el desarrollo de una herramienta de apoyo a la decisión multicriterio aplicada al Catálogo de Elementos constructivos del CTE se ha demostrado técnicamente viable y arroja resultados significativos. Se han diseñado dos sistemas constructivos mediante la aplicación de la herramienta desarrollada, uno de fachada no ventilada y otro de fachada ventilada. Comparados estos dos sistemas constructivos mejorados con otros sistemas constructivos analizados Se comprueba el alto grado de utilidad objetiva de los dos sistemas diseñados en relación con el resto. La realización de este ejercicio de diseño de un sistema constructivo específico, que responde a los requerimientos de un decisor concreto viene a demostrar, así pues, la utilidad del algoritmo propuesto en su aplicación a los procesos de diseño de los sistemas constructivos. La tesis incorpora dos innovaciones metodológicas y tres innovaciones instrumentales. ABSTRACT The starting point for the thesis is the hypothesis that it is possible to devise suitability degree evaluation methods of building enclosure systems. Such methods should allow optimizing appraisal, given a specific domain of decision, among a finite number of alternative systems, and provide objective justification of such decision. Along with the above mentioned general assumption, a second hypothesis whereby constructive systems based on the use of prefabricated components, or high industrialization degree work processes, would throw efficiency values higher than traditional masonry systems needed to be tested. In order to validate these two hypothesis a coherent set of twelve enclosure systems that could serve as a reference sample of their potential diversity was selected and a comparative evaluation was carried out. The valuation method proposed has considered several different factors that are neither reducible to a single parameter or magnitude that would allow a linear evaluation of their relative suitability nor allow to establishing an absolute priority ranking between different alternative constructive systems. In order to resolve this tour de force or methodological challenge, valuation methodologies that enable use establishing rational assessments were used. We are referring to a number of methodologies taken from the exact sciences field, usually known as aid methods for multi-criteria decision, in particular the so-called ELECTRE method. Even though the combination of the mentioned three basic categories result in eighteen conceptual sub categories, we are finally considering just twelve since we deem it adequately extended for the our intended purpose and eliminates non relevant instances. The method of analysis was initially applied to the set of twelve selected constructive systems is a way that they could represent adequately the three previously established categories set out to characterize all possible enclosure systems, namely weight, prefabrication degree and ventilation degree. Once the proposed method is applied to the sample systems, the higher efficiency of the prefabricated, heavy and not ventilated systems was confirmed. In line with the analysis in Part II of the thesis on the twelve chosen enclosure systems, it has done an uploading data of construction systems listed in the Catalogue of constructive elements of the CTE (version 2010) according the eighteen subcategories used in this part II to characterize the construction systems taken as sample. Subsequently, a parameterization of all enclosure facade systems included in this catalog has been undertaken. The systematic parameterization has allowed to set, by means of calculating the average values of the parameters of the systems belonging to the same family of those established by the Catalog, a comparative characterization of the efficiency degree of these families, both in relation to each parameter as to an overall evaluation of its values, in a indicative way. After the parameterization of all enclosure systems included in the Catalog, a simulation of validation methodology application developed in Part II of this Thesis has been made, in order to assess its consistency to the referred case. In conclusion, the development of a multi-criteria decision aid tool, applied to the CTE Catalog of constructive elements, has proved to be technically feasible and yields significant results. Two building systems through the application of the developed tool, a non-ventilated façade and a ventilated façade have been designed. Comparing these two improved construction systems with other building systems analyzed, we were able to assess the high degree of objective efficiency of the two systems designed in relation to the rest. The exercise of designing a specific enclosure system that meets the requirements of a particular decision-maker hence shows the suitability of the proposed algorithm applied to the process of enclosure systems design. This Thesis includes two methodological innovations and three instrumental innovations.

A prova ilícita na investigação de paternidade

A presente dissertação versa sobre a prova ilícita na investigação de paternidade, com a percepção que inexistem direitos e garantias absolutos. Sob esse ponto de vista, propõe-se a demonstrar que tanto o direito à prova quanto a garantia constitucional da inadmissibilidade da prova obtida por meios ilícitos são passíveis de sofrer restrições. Essas restrições, entretanto, não podem implicar na supressão de direitos e garantias fundamentais. Elas devem limitar-se ao estritamente necessário para a salvaguarda de outros direitos constitucionalmente protegidos, à luz de um juízo de ponderação entre os valores conflitantes. Os valores colidentes a serem analisados no presente trabalho são, por um lado, a proteção constitucional dispensada à intimidade, à vida privada, à imagem, à honra, ao sigilo da correspondência, às comunicações telegráficas, aos dados, às comunicações telefônicas e ao domicílio do suposto pai e, por outro, o direito do filho conhecer a sua origem genética e receber do genitor assistência material, educacional e psicológica, além da herança no caso de morte deste. Avultam-se, ainda, os comandos constitucionais da paternidade responsável (CF, o art. 226, § 7º) e da prioridade absoluta que a Constituição Federal confere às questões afetas à criança e ao adolescente. Nessa linha de perspectiva, procura conciliar o direito fundamental ao conhecimento da origem genética com a garantia constitucional que veda a obtenção da prova por meios ilícitos, reduzindo, quando necessário, o alcance de um desses valores contrastantes para que haja a preservação do outro e o restabelecimento do equilíbrio entre eles. Com o intuito de facilitar a compreensão do assunto, o estudo sobre a prova ilícita na investigação de paternidade encontra-se dividido em três capítulos. No primeiro capítulo são estudados o objeto da prova na investigação de paternidade, os fatos a provar, as teorias sobre o objeto da prova, o ônus da prova, a distribuição e a inversão do ônus da prova na investigação de paternidade, o momento da inversão do ônus da prova, o dever de colaboração e a realização do exame de DNA sem o consentimento das partes. Partindo da compreensão da prova como instrumento capaz de propiciar ao juiz o convencimento dos fatos pertinentes, relevantes e controvertidos deduzidos pelas partes como fundamento da ação ou da defesa, sustenta-se que os fatos a provar não são apenas os principais, mas, também, os acessórios que se situem na mesma cadeia deles. Desenvolve-se, outrossim, estudo sobre as teorias utilizadas pela doutrina para explicar o objeto da prova, a saber: a) a teoria clássica; b) a teoria da afirmação; c) a teoria mista. Nesse tópico, merece ênfase o fato das legislações brasileira e portuguesa estarem alicerçadas sob as bases da teoria clássica, em que pesem as divergências doutrinárias sobre o assunto. No item reservado ao ônus da prova, este é concebido como uma atividade e não como uma obrigação, diante da autonomia de vontade que a parte tem para comportar-se da maneira que melhor lhe aprouver para alcançar o resultado pretendido. Embora não traduza um dever jurídico demonstrar a veracidade dos fatos que ensejam a constituição do direito alegado, quem não consegue reunir a prova dos fatos que alega corre o risco de perder a demanda. No que tange à regra de distribuição do ônus da prova, recomenda-se a observação das disposições do art. 333 do CPC, segundo as quais incumbe ao autor comprovar o fato constitutivo do seu direito e ao réu a existência de fato impeditivo, modificativo ou extintivo do direito do autor. Argumenta-se que o CPC brasileiro adota o modelo estático de distribuição do ônus da prova, pois não leva em conta a menor ou maior dificuldade que cada parte tem para produzir a prova que lhe incumbe. Porém, ressalta-se o novo horizonte que se descortina no anteprojeto do novo CPC brasileiro que se encontra no Congresso Nacional, o qual sinaliza no sentido de acolher a distribuição dinâmica do ônus da prova. Esse novo modelo, contudo, não afasta aquele previsto no art. 333 do CPC, mas, sim, o aperfeiçoa ao atribuir o ônus a quem esteja em melhores condições de produzir a prova. Ao tratar do dever de colaboração, idealiza-se a busca descoberta da verdade como finalidade precípua do ordenamento jurídico. E, para se alcançar a justa composição da lide, compreende-se que as partes devem atuar de maneira escorreita, expondo os fatos conforme a verdade e cumprindo com exatidão os provimentos formais. Sob essa ótica, sustenta-se a possibilidade de inversão do ônus da prova, da aplicação da presunção legal de paternidade e até mesmo da condução coercitiva do suposto pai para a realização de exames, caso o mesmo a tanto se recuse ou crie, propositalmente, obstáculo capaz de tornar impossível a colheita da prova. Defende-se que a partir da concepção do nascituro, a autonomia de vontade dos pais fica restringida, de forma que a mãe não pode realizar o aborto e o pai não pode fazer pouco caso da existência do filho, recusando-se, injustificadamente, a submeter-se a exame de DNA e a dar-lhe assistência material, educacional e psicológica. É por essa razão que, em caráter excepcional, se enxerga a possibilidade de condução coercitiva do suposto pai para a coleta de material genético, a exemplo do que ocorre no ordenamento jurídico alemão (ZPO, § 372). Considera-se, outrossim, que a elucidação da paternidade, além de ajudar no diagnóstico, prevenção e tratamento de algumas doenças hereditárias, atende à exigência legal de impedir uniões incestuosas, constituídas entre parentes afins ou consanguíneos com a violação de impedimentos matrimoniais. Nesse contexto, a intangibilidade do corpo não é vista como óbice para a realização do exame de DNA, o qual pode ser feito mediante simples utilização de fios de cabelos com raiz, fragmentos de unhas, saliva e outros meios menos invasivos. O sacrifício a que se submete o suposto pai mostra-se, portanto, ínfimo se comparado com o interesse superior do investigante que se busca amparar. No segundo capítulo, estuda-se o direito fundamental à prova e suas limitações na investigação de paternidade, a prova vedada ou proibida, a distinção entre as provas ilegítima e ilícita, a manifestação e alcance da ilicitude, o tratamento dispensado à prova ilícita no Brasil, nos Estados Unidos da América e em alguns países do continente europeu, o efeito-à-distância das proibições de prova na investigação de paternidade e a ponderação de valores entre os interesses em conflito: prova ilícita x direito ao conhecimento da origem genética. Nesse contexto, o direito à prova é reconhecido como expressão do princípio geral de acesso ao Poder Judiciário e componente do devido processo legal, materializado por meio dos direitos de ação, de defesa e do contraditório. Compreende-se, entretanto, que o direito à prova não pode ser exercido a qualquer custo. Ele deve atender aos critérios de pertinência, relevância e idoneidade, podendo sofrer limitações nos casos expressamente previstos em lei. Constituem exemplos dessas restrições ao direito à prova a rejeição das provas consideradas supérfluas, irrelevantes, ilegítimas e ilícitas. A expressão “provas vedadas ou proibidas” é definida no trabalho como gênero das denominadas provas ilícita e ilegítima, servindo para designar as provas constituídas, obtidas, utilizadas ou valoradas com afronta a normas de direito material ou processual. A distinção que se faz entre a prova ilícita e a ilegítima leva em consideração a natureza da norma violada. Quando há violação a normas de caráter processual, sem afetar o núcleo essencial dos direitos fundamentais, considera-se a prova ilegítima; ao passo em que havendo infringência à norma de conteúdo material que afete o núcleo essencial do direito fundamental, a prova é tida como ilícita. Esta enseja o desentranhamento da prova dos autos, enquanto aquela demanda a declaração de nulidade do ato sem a observância da formalidade exigida. A vedação da prova ilícita, sob esse aspecto, funciona como garantia constitucional em favor do cidadão e contra arbítrios do poder público e dos particulares. Nessa ótica, o Direito brasileiro não apenas veda a prova obtida por meios ilícitos (CF, art. 5º, X, XI, XII e LVI; CPP, art. 157), como, também, prevê sanções penais e civis para aqueles que desobedeçam à proibição. A análise da prova ilícita é feita à luz de duas concepções doutrinárias, a saber: a) a restritiva - exige que a norma violada infrinja direito ou garantia fundamental; b) a ampla – compreende que a ilicitude afeta não apenas as normas que versem sobre os direitos e garantias fundamentais, mas todas as normas e princípios gerais do direito. A percepção que se tem à luz do art. 157 do CPP é que o ordenamento jurídico brasileiro adotou o conceito amplo de ilicitude, pois define como ilícitas as provas obtidas com violação a normas constitucionais ou legais, sem excluir àquelas de natureza processual nem exigir que o núcleo do direito fundamental seja atingido. Referido dispositivo tem sido alvo de críticas, pois a violação da lei processual pode não implicar na inadmissibilidade da prova e aconselhar o seu desentranhamento dos autos. A declaração de nulidade ou renovação do ato cuja formalidade tenha sido preterida pode ser suficiente para contornar o problema, sem a necessidade de exclusão da prova do processo. Noutra vertente, como a vedação da prova ilícita não pode ser levada às últimas consequências nem se converter em meio facilitador da prática de atos ilícitos e consagrador da impunidade, defende-se a sua admissão nos casos de estado de necessidade, legítima defesa, estrito cumprimento do dever legal e exercício regular de um direito. Assim, entende-se possível a utilização pela vítima de estupro, no processo de investigação de paternidade movido em prol do seu filho, do exame de DNA realizado mediante análise do sêmen deixado em sua vagina por ocasião do ato sexual que resultou na gravidez. Sustenta-se, ainda, a possibilidade de utilização das imagens captadas por circuito interno de câmaras comprobatórias do estupro para fazer prova da paternidade. Ressalta-se, outrossim, que no Brasil a doutrina e a jurisprudência têm admitido a prova ilícita, no processo penal, para comprovar a inocência do acusado e, em favor da vítima, nos casos de extorsão, concussão, sequestro e outros delitos similares. No ponto relativo ao efeito-àdistância das proibições de prova, aduz-se que as experiências americana e alemã da fruit of the poisonous tree doctrine e da fernwirkung são fonte de inspiração para as legislações de vários países. Por força da teoria dos frutos da árvore envenenada, o vício da planta transmite-se aos seus frutos. Ainda no segundo capítulo, estabelece-se breve comparação do tratamento conferido à prova ilícita nos ordenamentos jurídicos brasileiro e português, destacando-se que no regime de controle adotado pela Constituição da República Federativa do Brasil a prova ilícita é tratada como ineficaz e deve ser rejeitada de plano ou desentranhada do processo. Já na Constituição portuguesa adotou-se o regime de nulidade. Após o ingresso da prova ilícita no processo, o juiz declara a sua nulidade. O terceiro capítulo é dedicado ao estudo dos meios de prova e da incidência da ilicitude no processo de investigação de paternidade. Para tanto são eleitos os meios de prova enumerados no art. 212 do Código Civil, quais sejam: a) confissão; b) documento; c) testemunha; d) presunção; e) perícia, além do depoimento pessoal previsto no CPC, analisando a incidência da ilicitude em cada um deles. Má vontade a investigação de paternidade envolva direitos indisponíveis, isso não significa que as declarações das partes não tenham valor probatório, pois o juiz pode apreciá-las como elemento probatório (CC, art. 361º). Por meio do depoimento e confissão da parte são extraídas valiosas informações sobre o tempo, o lugar e a frequência das relações sexuais. Todavia, havendo emprego de métodos proibidos, tais como ameaça, coação, tortura, ofensa à integridade física ou moral, hipnose, utilização de meios cruéis, enganosos ou perturbação da capacidade de memória, a prova será considerada ilícita e não terá validade nem mesmo como elemento probatório a ser livremente apreciado pelo juiz. A prova documental é estudada como a mais vulnerável à incidência da ilicitude, pelo fato de poder expressar-se das mais variadas formas. Essa manifestação da ilicitude pode verificar-se por ocasião da formação da prova documental, no ato da sua obtenção ou no momento da sua exibição em juízo por meio falsificação material do documento público ou particular, da omissão de declaração deveria constar, inserção de declaração falsa ou diversa da que devia ser escrita, alteração de documento verdadeiro, emprego de métodos proibidos de prova para confecção do documento, etc. Na esteira desse raciocínio, em se fazendo constar, por exemplo, da escritura pública ou particular ou do testamento (CC, art. 1.609, II e III) declaração falsa da paternidade, a prova assim constituída é ilícita. Do mesmo modo, é considerada ilícita a prova obtida mediante indevida intromissão na vida privada, com violação de domicílio, emails, sigilos da correspondência, telefônico ou fiscal, realização de gravações, filmagens, etc. Na prova testemunhal entende-se como elemento configurador da ilicitude o emprego de métodos proibidos por parte de agentes públicos ou particulares, tais como tortura, coação, ameaça, chantagem, recursos que impliquem na diminuição ou supressão da capacidade de compreensão, etc, para que a testemunha faça afirmação falsa, negue ou cale a verdade dos fatos. Destaca-se, ainda, como ilícita a prova cujo acesso pela testemunha tenha ocorrido mediante violação à reserva da vida privada. No caso das presunções, vislumbra-se a possibilidade de incidência da ilicitude quando houver ilicitude no fato conhecido, do qual se vale a lei ou o julgador para extraírem as consequências para dedução da existência do fato desconhecido. A troca maliciosa de gametas é citada como meio ilícito de prova para alicerçar a presunção de paternidade no caso de inseminação artificial homóloga. A consecução da prévia autorização do marido, mediante coação, tortura, ameaça, hipnose, etc, na inseminação artificial heteróloga, também é tratada como ação danosa e capaz de viciar e infirmar a presunção legal de paternidade. Enxerga-se, outrossim, no meio de prova pericial, a possibilidade de maculação do resultado do exame por falha humana intencional no processo de coleta, transporte, armazenamento, manipulação ou troca do material genético coletado. Em se verificando essa situação, fica comprometida a credibilidade da prova pericial ante a sua ilicitude.

Ações de cuidado nas relações intrageracionais em crianças em acolhimento institucional

According to the Statute of Children and Adolescents (1990) children and adolescents are conceived as subjects of rights, with absolute priority and development peculiar condition. Thus, if these rights were violated or threatened, will be applied protection measures. Within these measures, in that Statute, the foster institutional is proposed, with transitional and exceptional character. When the child goes out from family and community life, and she is upheld in an institution, the child is placed in a new development context, therefore, with new people, new places, and new relationships. According with Socio-Historical Psychology, theoretical support of this study, each context presents specific demands of socialization that influence child development and her subjectivity is constituted through the relations that the subject establishes in each context. These contexts bring challenges and proposals for the child and she needs to respond these. Then, whereas he is in relation to the other, in this moment, the subject is constituted, the interactions established during the foster institutional will be of paramount importance to the child. Among these interactions, we can cite situations involving aspects of moral development, specifically those that can ask (or not) the exercise of the virtues. About the intersection between these actions can then arise care actions beyond those involving the attending of an emerging need. The objective of this study is to investigate the presence of relation everyday permeated by care actions among children in foster institutional. For the scope of the objective three children were participated, with three years old and in foster care measure. The research is qualitative and the procedure for building the corpus was, mainly, the participant observation. Procedures with video and history in books were also used as supplementary procedures. The analysis of the corpus was made through Thematic Content Analysis, the episodes were grouped into analysis categories pre-and post-established. The preestablished were care actions related to body care, care actions related to socio affective aspects, and care actions related to body care and socio affective aspects simultaneously. The two post-established categories were dismemberment of the preceding categories, called care actions developed in child-child interaction, without the intervention of an adult, and care actions developed in child-child interaction, with direct intervention of the educator. The analysis indicated that in the everyday interaction between foster children, they identify the physical and emotional needs of each other foster member, and they are willing to help them in whatever way they can, emphasizing the importance of play and playful moments like mediators about these interactions. The care actions observed are based on children´s concepts and interpretations made from their experiences and largely refer to maternal care. The condition of being away from their family life can be an element that enables these actions. Finally, this study reaffirms the importance of designing the foster institution as a socialization and care space. It follows the importance of valuing and strengthening the positive aspects that arise in the relationships established by the children in this context, including the care actions, the research objective, which are components of the subjectivity of these children

Key performance indicators (KPIs) and priority setting in using the multi-attribute approach for assessing sustainable intelligent buildings

The main objectives of this paper are to: firstly, identify key issues related to sustainable intelligent buildings (environmental, social, economic and technological factors); develop a conceptual model for the selection of the appropriate KPIs; secondly, test critically stakeholder's perceptions and values of selected KPIs intelligent buildings; and thirdly develop a new model for measuring the level of sustainability for sustainable intelligent buildings. This paper uses a consensus-based model (Sustainable Built Environment Tool- SuBETool), which is analysed using the analytical hierarchical process (AHP) for multi-criteria decision-making. The use of the multi-attribute model for priority setting in the sustainability assessment of intelligent buildings is introduced. The paper commences by reviewing the literature on sustainable intelligent buildings research and presents a pilot-study investigating the problems of complexity and subjectivity. This study is based upon a survey perceptions held by selected stakeholders and the value they attribute to selected KPIs. It is argued that the benefit of the new proposed model (SuBETool) is a ‘tool’ for ‘comparative’ rather than an absolute measurement. It has the potential to provide useful lessons from current sustainability assessment methods for strategic future of sustainable intelligent buildings in order to improve a building's performance and to deliver objective outcomes. Findings of this survey enrich the field of intelligent buildings in two ways. Firstly, it gives a detailed insight into the selection of sustainable building indicators, as well as their degree of importance. Secondly, it tesst critically stakeholder's perceptions and values of selected KPIs intelligent buildings. It is concluded that the priority levels for selected criteria is largely dependent on the integrated design team, which includes the client, architects, engineers and facilities managers.
