Full textAbstract:
International Telemetering Conference Proceedings / October 20-23, 2003 / Riviera Hotel and Convention Center, Las Vegas, NevadaWhile healthcare industry is striving to achieve e-health systems for improvements in healthcare quality, cost, and access, privacy and security about medical records should be considered carefully. This paper makes a deep study of Public Key Infrastructures (PKIs) and Privilege Management Infrastructures (PMIs) and how they can secure e-health systems. To access resources, e.g. patient records, both authentication and authorization are needed, so public key certificates and attribute certificates are both required to protect healthcare information. From a typical medical scenario, we see not only static but also dynamic permissions are required. Dynamic authorization maybe the most complex problem in e-health systems.

Full textAbstract:
2011/2012We present a search for physics beyond the standard model (SM) through a measurement of the violation of the charge-parity (CP) symmetry in two decays of the Bs meson using data collected by the Collider Detector at Fermilab (CDF) in proton-antiproton collisions at the center-of-mass energy of 1.96 Tev. We exploit the decays Bs->Jpsi (->mu mu) phi(-> KK) and Bs -> phi(-> KK) phi(-> KK), for which the SM accurately predicts very small or vanishing CP violation; both decay modes are very sensitive to new sources of CP violation expected in a broad class of SM extensions. We analyze the time-dependent CP asymmetry of the Bs->Jpsi phi decays collected in the full CDF Run II dataset for providing the final measurement of the Bs-antiBs mixing phase, 2*betas, and we present the first measurement of CP violation in Bs -> Phi Phi decays, through the determination of two time-integrated CP asymmetries, Av and Au, using an original method developed in this work. We find: -0.06< betas<0.30 at the 68% confidence level; Av=(-12.0 +/-6.4(stat) +/- 1.6(syst))%; and Au=(-0.7 +/-6.4(stat) +/- 1.8(syst))%. In addition, we provide measurements of the decay width difference between the light and heavy mass eigenstates of the Bs meson, DeltaGamma_s=0.068 +/- 0.026(stat) +/- 0.009(syst) ps^{-1}; and of their mean lifetime, tau_s=1.528 +/- 0.019(stat) +/- 0.009(syst) ps. All results are among the most precise determinations from a single experiment and exhibit an excellent agreement with the SM predictions. They have been published in two letters in Physical Review.

In this dissertation, we present the results of a time-dependent angular analysis of Bs -+ J/,0 decays performed with the use of initial-state flavor tagging. CP violation is observed in this mode through the interference of decay without net mixing and decay with net mixing, that is, Bs -- J/0 and Bs -+ B, -+ J/q0. The time-dependent angular analysis is used to extract the decay widths of the heavy and light B, eigenstates and the difference between these decay widths AF, - FL - FH. Initial-state flavor tagging is used to determine the matter-antimatter content of the B. mesons at production time. We combine flavor tagging with the angular analysis, which statistically determines the contributions of the CP-even and CP- odd components at decay time, to measure the CP-violating phase 0,. The phase 3, is expressed in terms of elements of the Cabibbo-Kobayashi-Maskawa matrix as s - arg (-VtsV4/VcsV*b), and is predicted by the Standard Model to be close to zero, O3SM = 0.02. In the measurement of AF,, we use a dataset corresponding to 1.7 fb- of luminosity, collected at the CDF experiment from proton-antiproton collisions at a center of mass energy f = 1.96 TeV. In the measurement of Ps, we use a dataset corresponding to 1.3 fb-1 of collected luminosity. We measure AF, = (0.071+0.064 ± 0.007) ps-1 using the time-dependent angular analysis. Combining the angular analysis with flavor-tagging, we find that assuming the Standard Model predictions of p/ and AF,, the probability of a deviation as large as the level of the observed data is 33%. We obtain a suite of associated results which are discussed in detail in this dissertation alongside the main results.

Recherche de nouvelle physique dans le canal B0s --> J/psi phi auprès de l'expérience LHCb: Dans le Modèle Standard, la différence de phase apparaissant dans la désintégration B0s --> J/psi phi est prèdite avec une grande précision. Cette observable est une sonde pour mettre en évidence de la Nouvelle Physique car l'oscillation B0s -B0sbar s'effectue via un diagramme en boucles sensible à la nouvelles particules. Nous avons développé une sélection simplifiée pour les données de 2010. Elle évite tous biais sur la distribution en temps propre afin de réduire l'incertitude systématique. De plus, nous contrôlons les performances d'étiquetage pour les événements B0s --> J/psi phi en utilisant les canaux similaires B0d--> J/psi K*0 et B+ --> J/psi K+. Avec les données de 2010, nous obtenons 570 événements de signal avec une luminosité intégré de 36 pb−1, une puissance de d'étiquetage de (2, 2 ± 0, 4)% et une résolution temporelle de 50 fs. Nous avons étudié une sélection alternative, qui maximise la sensibilité à la phase phis en utilisant des coupures biasant le temp propre. Nous avons proposé une méthode pour corriger la déformation de temps propre à partir des données. Nous avons développé un programme d'ajustement pour déterminer la phase phis. Avec les données 2010, la valeur touveé est phis = [−2, 7,−0, 5] rad à 68% de confiance. Ce résultat est compatible avec la prédiction du Modèle Standard.

Full textAbstract:
El texto completo de este trabajo no está disponible en el Repositorio Académico UPC por restricciones de la casa editorial donde ha sido publicado.A pavement management system (PMS) is a tool that supports decision-making specialists to maintain the pavement at an optimal service level. The absence of a PMS could lead to inadequate decision-making, a disorganized road inventory, poor selection in road maintenance techniques and inefficient technical support to justify the execution of maintenance activities. For these reasons, this research proposes the application of a PMS, with the objective of improving and standardizing the processes for evaluating the condition of roads that are under the jurisdiction of low-budget government organizations, guaranteeing the selection of the most appropriate type of maintenance. As a case of study, a 1.1 km local road located in one of the districts of Lima was evaluated, which was divided into 11 sections. With this evaluation, it was obtained that 2,605.43 m2 of the total road is in poor condition, due to the presence of functional failures. For the identification of failures, the pavement condition index (PCI), the international roughness index (IRI) and the present serviceability index (PSI) were used to determine the condition, roughness and serviceability of the pavement. In conclusion, it was identified that the proposed PMS is adequately adapted to the way of working and available budget of a local administration, since if it is applied it would only spend 20.55% of the fund that would be destined to a total reconstruction of road.

Full textAbstract:
La mesure de la phase phis violant la symétrie CP dans les désintégrations Bs -> J/psi phi est une des analyses phares de l'expérience LHCb. Le Modèle Standard prédit cette observable avec une faible incertitude théorique. La présence de Nouvelle Physique notamment dans les diagrammes en boucle de l'oscillation Bs - anti Bs peut significativement modifier la mesure de cette phase. Durant cette thèse, nous avons participé à différents aspects de l'analyse des désintégrations Bs -> J/psi phi. Nous avons proposé une sélection multi-variables, basée sur un algorithme d'arbres de décision boostés. Cette nouvelle sélection augmente le nombre de signal Bs -> J/psi phi de 19% mais nécessite une correction temporelle. Une étude portant sur l'origine des distorsions angulaires caractéristiques des désintégrations Bs -> J/psi phi a aussi été menée. Il s'avère que la principale source de distorsion est la géométrie du détecteur LHCb. Nous avons aussi contribué à un autre élément clef de cette analyse : l'étiquetage de la saveur. Afin de connaître la saveur initiale des mésons B, un algorithme d'étiquetage a été développé. Il exploite les traces chargées provenant du hadron B de côté opposé. Nous avons participé à son optimisation ainsi qu'à son étalonnage en étudiant les désintégrations Bd -> J/psi K*. En utilisant l'intégralité des données enregistrées en 2011, soit 1 fb-1, après optimisation et calibration de cet algorithme, la puissance d'étiquetage dans le canal Bs -> J/psi phi est : (2.29 +- 0.07 +- 0.26) %. La valeur de phis mesurée est alors : \phis = -0.001 +- 0.101 +- 0.027 rad dans les désintégrations Bs -> J/psi phi. L'analyse combinée de Bs -> J/psi phi avec les désintégrations Bs -> J/psi \pi+ \pi- donne la meilleure mesure mondiale de \phis = -0.002 +- 0.083 +- 0.027 rad. Cette mesure est compatible avec le Modèle Standard, mais ses incertitudes laissent possible la présence de Nouvelle Physique.

Full textAbstract:
Background: Food allergy affects an estimated 8% of children and 3% of adults in the United States. Food‐allergic individuals increasingly use the web for medical information. We sought to determine the educational quality of food allergy YouTube videos.
Methods: We performed a YouTube search using keywords “food allergy” and “food allergies”. The 300 most viewed videos were included and analyzed for characteristics, source, and content. Source was further classified as healthcare provider, alternative medicine provider, patient, company, media, and professional society. A scoring system (FA‐DQS) was created to evaluate quality (−10 to +34 points). Negative points were assigned for misleading information. Eight reviewers scored each video independently.
Results: Three hundred videos were analyzed, with a median of 6351.50 views, 19 likes, and 1 dislike. More video presenters were female (54.3%). The most common type of video source was alternative medicine provider (26.3%). Alternative treatments included the following: water fast, juicing, Ayurveda, apple cider, yoga, visualization, and sea moss. Controversial diagnostics included kinesiology, IgG testing, and pulse test. Almost half of the videos depicted a non‐IgE‐mediated reaction (49.0%).Videos by professional societies had the highest FA‐DQS (7.27). Scores for videos by professional societies were significantly different from other sources (P < .001). There was a high degree of agreement among reviewers (ICC = 0.820; P < .001).
Conclusion: YouTube videos on food allergy frequently recommend controversial diagnostics and commonly depict non‐IgE‐mediated reactions. There is a need for high‐quality, evidence‐based, educational videos on food allergy.

This thesis presents an automated tool for manipulation and analysis of mobile concurrent systems described in the Psi-calculi framework. Psi-calculi is a family of process calculi, parameterised on data, conditions and a logic. We provide a general framework for implementing instantiations of these parameters, yielding a Psi-calculus. The tool implements simulation of Psi-calculus processes based on symbolic operational semantics, process constants for providing an environment for processes, and a symbolic bisimulation algorithm for checking bisimilarity. The tool has a command interpreter frontend for interactive use.

Full textAbstract:
Estuda as experiências anômalas (EAs), as quais podem ser definidas como incomuns e irregulares, ainda que vivenciadas por uma grande parcela da população. Dentre a variedade de EAs, concentra-se nas experiências relacionadas a psi, que incluem duas categorias. A primeira abrange relatos de percepção extra-sensorial (ESP), ou seja, indicativos da capacidade de se obter informação sem a utilização dos canais sensoriais ou de inferências lógicas. A segunda é chamada de Psicocinesia (PK) e refere-se a relatos da ação ou efeito da mente sobre a matéria, ou seja, quando as preferências ou pensamentos de pessoas parecem afetar o ambiente físico, sem a mediação do sistema muscular ou outra força física ou mecanismo físico reconhecido. Investiga se: a) é possível treinar pessoas para estarem mais aptas para perceber e utilizar os fenômenos psi no contexto experimental e b) se a manipulação de certos fatores pode aumentar significativamente os índices de psi em laboratório. Para tanto, revisa e discute por meio de sistematização a eficácia das pesquisas de treinamentos psi (TP) e os resultados de estudos que manipulam variáveis consideradas psicondutivas (VCP). Agrupa os estudos nestas duas categorias (TP e VCP), considerando variáveis específicas e comuns para os dois grupos. Avalia os estudos em blocos, segundo as variáveis consideradas, com ênfase nos dados estatísticos e do método. A revisão da literatura ocorre de março de 2007 a fevereiro de 2008 e abrange livros e artigos científicos relacionados ao tema. 128 estudos são revisados, sendo 87 deles relacionados a manipulação de VCP e 41 relacionados ao TP, totalizando 9.153 participantes em 845.815 ensaios. Avalia que 37% dos estudos TP são criticados, sendo a maior parte das críticas endereçada a problemas de método, enquanto que 16% dos estudos VCP recebem críticas. Conclui que os estudos não são eficazes em treinar psi ou manipular variáveis psi-condutivas, ainda que a maior parte deles obtenha resultados significativos e na direção esperada. De uma forma geral eles falham em termos da elaboração de métodos capazes de excluir hipóteses alternativas àquelas testadas, sendo que as principais falhas são: 1. falta de grupos controle; 2. controle inadequado da variável crença, tanto em relação aos sujeitos como aos pesquisadores; 3. falha em avaliar o real aprendizado; a maioria dos estudos são de curta ou curtíssima duração e sem a avaliação e/ou correlação dos fatores, aos quais se atribui aprendizado, com os escores psi. Com exceção de um estudo, os demais não apresentam testes posteriores para verificar a possível manutenção dos níveis de psi alcançados; 4. o efeito experimentador psi e psicológico é amplamente ignorado pela maioria dos estudos; 5. falta de parâmetros padrões para avaliar determinadas características ou estados (ex. hipnose, meditação, ganzfeld); 6. falta de uma abordagem sistêmica e integrada em relação aos fenômenos psi, aos métodos para testá-los e as múltiplas variáveis passíveis de influenciá-lo. Considera estas falhas apresentando sugestões para superá-las e uma proposta inicial exploratória de treinamento psiThis dissertation is about studies of anomalous experiences (AEs), which can be defined as uncommon and irregular, but reported by a large segment of the population. Among the variety of AEs, this work concentrates on psi-related experiences, which includes two categories. The first are reports of extrasensory perception (ESP), which suggest the capacity of obtaining information without the use of the sensory channels or logical inference. The second is called of psychokinesis (PK), which refers to reports of the action or effect of the mind on matter, or when people\'s thoughts seem to affect the physical environment, without the mediation of the muscular system, a physical force, or a recognized physical mechanism. The study explores if: a) it is possible to train people to be more capable to perceive and use psi phenomena in the experimental context and, b) if the manipulation of some factors can increase psi scores significantly in the laboratory. A review of the research on the effectiveness of psi trainings (PT) and of studies that manipulate psi-conductive variables (PCV) is presented. The studies are grouped in these two categories (PT and PCV), considering specific and common variables for both groups. Studies are evaluated in subgroups, according to specific variables, with emphasis on statistics and methods. The literature review was conducted from March 2007 to February 2008, and it includes books and scientific papers on the topic. 128 studies are reviewed; 87 of them about the manipulation of VCP and 41 of TP, for a total of 9.153 participants in 845.815 trials. 37% of the TP studies are criticized, mostly on methodological grounds, while the same was the case for 16% of the VCP studies. Although most of the studies obtained significant results in the expected direction, it is concluded that they are not effective to train psi or to manipulate psiconductive variables. In general they fail in terms of the elaboration of methods capable to exclude alternative hypotheses, and the main flaws are: 1. lack of control groups; 2. inappropriate control of the variable of belief, for both the subjects and researchers; 3. lack of evaluation of learning; most of the studies were of brief duration and without the evaluation and/or correlation of the factors to which learning is attributed, and in relation to psi scores. With the exception of one study, the rest do not present subsequent analyses to verify the possible maintenance of the psi levels obtained; 4. the experimenter effect (psi and psychological) is ignored completely in most of the studies; 5. lack of standard parameters to evaluate certain characteristics or states (for example hypnosis, meditation, ganzfeld); 6. lack of a systemic and integrated approach in relation to psi phenomena, to the methods used to test them, and to multiple variables that may influence them. In addition to discussing these problems, suggestions are presented to improve the situation, together with an exploratory initial proposal for psi training

La sécurité est un enjeu majeur des technologies numériques modernes. Avec le développement de l'Internet, les besoins de sécurité sont de plus en plus importants. Le développement d'applications Internet telles que le commerce électronique implique de nouveaux besoins comme, l'identification des entités communicantes, l'authentification des entités, l'anonymat du propriétaire du certificat, la procuration, etc. Qu'il s'agisse de données médicales, fiscales ou bancaires, le besoin en sécurité est essentiel afin de crédibiliser le système, tout en respectant à la fois les besoins des utilisateurs et des applications. Cette sécurité a néanmoins un prix : celui de l'établissement de la confiance entre les partenaires en communication. La confiance des utilisateurs passe par la sécurisation des transactions, par exemple au moyen d'une procédure de certification, et la reconnaissance des signatures électroniques. Malgré la diversité des certificats numériques existants (certificat d'identité X509, SPKI, certificat d'attributs, etc. ), ils sont encore limités, génériques et répondent ainsi insuffisamment aux besoins spécifiques des applications électroniques et des utilisateurs. D'où la nécessité de spécifier une nouvelle approche pour la génération de certificats numériques répondant à ces exigences, légers, simplifiés et plus ouverts que ceux existants. Les travaux de recherche présentés dans cette thèse consistent à proposer une nouvelle approche pour la génération de certificats numériques pour contribuer aux services d'autorisation, puis à intégrer cette contribution au protocole d'attribution dynamique des adresses DHCP afin de renforcer sa sécurité. Security is a major stake of modern numerical technologies. With the development of the Internet, the needs for security are increasingly becoming more important than ever before. The development of Internet applications such as e-business, medical applications or videoconference, implies new needs such as, identification of the communicating entities, integrity of the exchanged messages, confidentiality of the transaction, authentication of the entities, anonymity of the certificate owner, procuration, etc. Whether they are medical, tax or banking related data, the requirement in security is essential in order to give credibility to the system, while respecting at the same time users' and applications' needs. This security has nevertheless a price: that of the establishment of trust between communicating partners. Users' trust goes through transactions security, for example by means of a certification procedure, and the recognition of electronic signatures. Despite the diversity of existing certificates (X. 509 identity certificate, SPKI, attributes certificate, etc), they are still limited, generic and thus, meet insufficiently the specific needs of electronic applications and users. Hence, the need for specifying a new approach for the generation of certificates answering these requirements, light, simplified and more open than those existing. The research tasks presented in this thesis consist in proposing a new approach for the generation of certificates to contribute to the authorization services, then to integrate this contribution to DHCP (Dynamic Host Configuration Protocol) in order to reinforce its security

Full textAbstract:
Psi-calculi are mobile process calculi, parametrised with arbitrary nominal datatypes representing data, communication channels, assertions and conditions, as well as morphisms over those datatypes. The framework for psi-calculi has been formalised in the interactive theorem prover Isabelle, along with both strong and weak bisimulation. This master's thesis project presents a tool for formally verifying that psi-calculus candidates are well-defined within the Isabelle/HOL-Nominal framework. It employs custom-made, heuristic proof tactics that discharge as many proof obligations as possible automatically, and passes any remaining proof obligations back to the user, who must supply manual proofs. The implementation of the tool as well as the proof strategies employed are described. The tool is applied to verify encodings of both the monadic and polyadic variants of the pi-calculus, as well as the pi-F calculus.

The index is based on a monthly survey answered by hundreds of purchasing managers in the manufacturing business all over the United States. The questions capture the activities of companies when it comes to orders, production, employment, supplier deliveries and inventories. PMI is an important and reliable macro economic factor and has shown a high correlation with the GDP which means that it may be of interest for a bank as Nordea to predict it. The purpose of this thesis is to evaluate whether it is possible to use neural networks, more precisely sequence-to-sequence models and recurrent neural networks, to forecast PMI with a multivariate data set. Simpler methods and models are also evaluated and compared to the neural networks. In total, there was two naive models, one Autoregressive Moving Average (ARMA) model, two linear regression models, and three neural network models that was implemented and compared to each other. All models were evaluated by their mean squared error (MSE) and mean absolute error (MAE). By analyzing MSE and MAE for the different models it is shown that the ARMA-model predicted only slightly better than the persistence algorithm which assumes that PMI next month equals PMI current month. Only one neural network model performed better compared to the linear regression models, and the same model also gave a better prediction compared to the persistence algorithm.

Full textAbstract:
The popular tourist destination island of Koh Phi Phi Don, Thailand was heavily affected by the Indian Ocean Tsunami in December 2004, which resulted in a destroyed tourism infrastructure and complete downturn of tourism. Extensive recovery and rebuilding work by emerging community groups, returned locals, international volunteers and Thai government units provided an efficient but hasty reconstruction of the destination. Ethnographic research conducted in the community provided insights into the complex stakeholder interactions and their roles and influences on the reconstruction of the community.
The community�s level of vulnerability on Koh Phi Phi Don was influenced by social processes and interactions during the destination�s recovery process as the various stakeholders (e.g. government vs. locals) had differing perceptions of the island�s economic, environmental and social vulnerability. These disputes are grounded in different social time processes, particularly illustrated through land law disputes among locals, landowners and the government. Other factors which influenced the reconstruction of Koh Phi Phi as a tourist destination were pre-tsunami conditions (past overdevelopment), the empowerment of the community, the reconstructed place identity, various anniversary celebrations and the early warning system.
A model is suggested to illustrate and discuss Koh Phi Phi Don as a disaster destination, which provides insights into the dynamics which govern a destination�s post-disaster recovery period. Thus, it illustrates how stakeholder interaction is influenced by distinct understandings of the multiple notions of vulnerability. Furthermore, this study establishes essential links between disaster and tourism theories and suggests an extended tourism disaster management framework, which calls for an inclusion of post-recovery processes.

Full textAbstract:
Tese (doutorado)—Universidade de Brasília, Instituto de Psicologia, Programa de Pós-graduação em Psicologia Clínica e Cultura, 2018.Às voltas com as mudanças familiares na sociedade vienense, no final do século XIX, e com a sexualidade histérica, Sigmund Freud atentou-se para a questão do pai, inserindo-a no campo da psicanálise. A propósito disso, o presente estudo consiste em uma proposta de investigação teórica sobre a questão do pai à luz da psicanálise, tendo como objetivo investigar a noção de pai, redimensionando-a no campo da psicanálise. Particularmente, buscou-se que os operadores conceituais da psicanálise fossem reconsiderados, fundamentalmente no que diz respeito à questão do pai em relação ao declínio da imago paterna e suas eventuais repercussões na constituição subjetiva. Acerca disso, percorreu-se como a noção de pai surgiu, desenvolveu-se e foi trabalhada na obra freudiana. De início, o pai foi apreendido enquanto sedutor e associado à etiologia das neuroses. Entretanto, a teoria da sexualidade infantil promoveu uma torção, deslocando o pai para o complexo de Édipo. Nesse, o pai seria o interditor do objeto de desejo e, simultaneamente, o ideal, na medida em que detém para si a mãe ao possuir o falo. Essa relação ambivalente, ou seja, de rivalidade e idealização, foi nomeada de complexo paterno, aspecto fundamental na noção de pai. Situando essa questão nas origens da humanidade, Freud formulou o mito do parricídio inaugural. O Urvater, o pai primordial, foi assassinado pelos filhos e, mesmo morto, tornou-se mais forte que se vivo estivesse. Semelhantemente, Moisés teria sido assassinado pelos judeus ao conduzi-los à terra prometida. Nas três principais versões freudianas do pai (Édipo, Urvater e Moisés), o parricídio está presente. O pai, o Um da exceção, é, a rigor, o pai morto, aquele cujo lugar ninguém está efetivamente à altura. De modo semelhante, investigou-se o declínio do pai e a problemática de suas eventuais repercussões na obra do jovem Lacan, na qual repercussões foram tributadas ao declínio da família paternalista, bem como eventuais falhas na constituição subjetiva atribuídas ao pai no seio familiar. Foi visto que essa lógica da contração familiar como prejudicial à constituição subjetiva está presente mesmo atualmente. Contrapondo-se a essa perspectiva, a problemática do pai também foi considerada em o “retorno a Freud” feito por Lacan, período no qual a noção de pai passou a ser apreendida a partir do caráter linguajeiro, sendo cunhado o conceito de Nome-do-Pai enquanto suporte da função simbólica. Distanciando-se do familialismo, é numa função lógica que o pai foi situado. Com isso, esta tese procurou investigar o que é o pai em psicanálise, essencialmente na teoria freudiana e nas (re)leituras produzidas por Lacan, contrapondo-se ao uso que se faz atualmente das noções de “enfraquecimento” ou “declínio” da função paterna, redimensionando essas questões no campo da psicanálise e defendendo a hipótese segunda a qual há uma radical distinção entre os pais, que estão sempre aquém, e a função paterna enquanto tal.
In view of family changes in Viennese society at the end of the nineteenth century, and with hysterical sexuality, Sigmund Freud occupied himself at the question of the father, inserting it into the field of psychoanalysis. In this regard, the present study consists of a theoretical research on the question of the father in the light of psychoanalysis, aiming to investigate the notion of father, redimensioning it in the field of psychoanalysis. Particularly, it has tried to reconsider the conceptual operators of psychoanalysis, fundamentally what it comes to the question of the father in relation to the decline of paternal imago and its possible repercussions on subjective constitution. Regarding this, it was studied how the idea of father arose, developed and was worked out in Freudian literature. At first, the father was apprehended as seductive and associated with the etiology of the neuroses. However, childhood sexuality promoted a twist, shifting the father to the Oedipus complex, in which the father would be the interdictor of the object of desire and, simultaneously, the ideal, considering that he holds for himself the mother as he possesses the phallus. This ambivalent relation, that is, of rivalry and idealization, was named paternal complex, fundamental aspect in the notion of father. Contextualizing this question in the origins of humanity, Freud formulated the myth of the inaugural parricide. Urvater, the primordial father, was murdered by his sons and, even dead, became stronger than if he were alive. Similarly, Moses have been murdered by the Jews when leading them to the promised land. In the three major Freudian versions of father (Oedipus, Urvater, and Moses), parricide is present. The father, the One of the exception, is, strictly speaking, the dead father, the one whose place no one is effectively up to. In a similar way, the present study also investigated father's decline and the problematic of its eventual repercussions in the work of young Lacan, in which repercussions were tributed to the decline of the paternalistic family, as well as possible failures in the subjective constitution attributed to the father within the family. It has been seen that this logic of family contraction as detrimental to the subjective constitution is present even today. In contrast to this perspective, the father's problematic was also considered in Lacan's "return to Freud", a period in which the notion of father became apprehended by the character of langage, and the concept of the Name-of-Father was coined as support of the symbolic function. Distancing itself from familialism, it was in a logical function that the father was placed. Thus, this thesis sought to investigate what the father is in psychoanalysis, essentially in Freud's theory and in the (re)readings produced by Lacan, in opposition to the current use of notions of "weakening" or "decline" of function paternal, redimensioning these issues in the field of psychoanalysis and defending the hypothesis according which there is a radical distinction between the fathers, who always fall short, and the paternal function.

Full textAbstract:
This thesis presents the development and optimization of an algorithm used to determine the flavour at production time of neutral B^0 and B_s^0 mesons. The flavour tagging algorithm developed in this thesis exploits muons and electrons produced in the semileptonic decay of the additional b-hadron produced in pp -> bbX collisions at the LHC. The charge of the lepton is used to infer the flavour of the neutral b-meson. Three simulated samples of B_s^0 -> J/psi phi, B^+ -> J/psi K^+ and B^0 -> J/psi K* decays are exploited to develop and test the algorithm. Two independent neural networks are defined for muons and electrons, trained on 24 000 and 20 400 simulated B_s^0 -> J/psi phi events respectively, to parametrize the probability of wrong flavour tag omega of the algorithm. The tagging performances are further measured and calibrated on a sample of self-tagging B^+ -> J/psi K^+ decays collected by the CMS experiment during 2012, corresponding to 20 fb^-1 . The charge of the kaon univocally determines the flavour of the B^+ at production time and allows the direct measure of the mis-identification probability. A tagging power P_tag = epsilon_tag (1 - 2 omega )^2 of 0.833 +/- 0.024 (stat.) +/- 0.012 (syst.) % is measured using muons and 0.483 +/- 0.020 (stat.) +/- 0.003 (syst.) % using electrons. Combining the two algorithms results in the overall tagging power of 1.307 ± 0.031 (stat.) ± 0.007 (syst.) %.
The combined lepton flavour tagging algorithm is used in the measurement of the charge-parity (CP) violation parameters phi_s and DeltaGamma_s , sensitive to potential new physics processes not included in the standard model description. A time-dependent and flavour-tagged full angular analysis of the mu^+ mu^- K^+ K^- final state of the B_s^0 -> J/psi phi decay is performed based on the 2012 CMS dataset. A total of 49 000 reconstructed B_s^0 decays are used to extract the weak phase phi_s and decay with difference DeltaGamma_s values:
phi_s = -0.075 +/- 0.097 (stat.) +/- 0.031 (syst.) rad
DeltaGamma_s = 0.095 +/- 0.013 (stat.) +/- 0.007 (syst.) ps^-1In questa tesi e' presentato lo sviluppo e l'ottimizzazione di un algoritmo per la determinazione del sapore di produzione di mesoni neutri B^0 e B_s^0 , che sfrutta muoni ed elettroni prodotti nel decadimento semileptonico dell'altro adrone-b prodotto nel processo pp -> bbX a LHC. La carica dei leptoni e' utilizzata per identificare il sapore del mesone-b neutro. Tre campioni di eventi simulati contenenti i decadimenti B_s^0 -> J/psi phi, B^+ -> J/psi K^+ e B^0 -> J/psi K^+ sono sfruttati per lo sviluppo e il controllo delle prestazioni dell'algoritmo. Due reti neurali sono definite separatamente per muoni ed elettroni ed utilizzate per parametrizzare la probabilita' di errata attribuzione del sapore omega dell'algoritmo, utilizzando rispettivamente 24 000 e 20 400 eventi simulati contenenti decadimenti B_s^0 -> J/psi phi. Le prestazioni dell'algoritmo sono inoltre misurate e calibrate su un campione di eventi B^+ -> J/psi K^+ raccolti dall'esperimento CMS nel corso del 2012, pari a 20 fb^-1 . La carica del kaone determina univocamente il sapore del B+ al momento della produzione e consente la misura diretta della probabilita' di errata attribuzione del sapore. Il potere di identificazione dell'algoritmo P_tag = epsilon_tag (1 - 2 omega )^2 , e' misurato essere pari a 0.833 +/- 0.024 (stat.) +/- 0.012 (syst.) % per i muoni e 0.483 +/- 0.020 (stat.) +/- 0.003 (syst.) % per gli elettroni. Il potere di identificazione risultante dalla combinazione dei due algoritmi e' 1.307 +/- 0.031 (stat.) +/- 0.007 (syst.) %. L'algoritmo combinato di identificazione del sapore e' utilizzato nella misura dei parametri phi_s e DeltaGamma_s di violazione della simmetria CP, sensibili a potenziali processi di nuova fisica non inclusi nella descrizione del modello standard. Utilizzando il campione di dati raccolti dall'esperimento CMS nel corso del 2012, e' eseguita una analisi angolare dipendente dal tempo dello stato finale mu^+ mu^- K^+ K^- del decadimento B_s^0 -> J/psi phi, includendo nell'analisi l'algoritmo di identificazione del sapore. Un totale di 49 000 decadimenti ricostruiti del mesone B_s^0 sono utilizzati per estrarre il valore sperimentale della fase debole phi_s e la differenza di vita media DeltaGamma_s : phi_s = -0.075 +/- 0.097 (stat.) +/- 0.031 (syst.) rad DeltaGamma_s = 0.095 +/- 0.013 (stat.) +/- 0.007 (syst.) ps^-1

Full textAbstract:
In this thesis project we focus on the implementation of a type system in a tool called Psi-calculi Workbench. Psi-calculi is an attempt to generalize a family of process calculi based on a parametric approach. Instantiating parameters of the psi-calculi framework (namely: data, conditions and assertions) results in a psi-calculus. The implementation of the type system is based on an existing specification with some extensions which we add to it. The original idea behind the psi-calculi type system is to keep it as generic as possible, with minimum dependency to the specific psi instances. Due to this requirement imposed by the theory, we try to keep the implementation of the type system as generic as possible. This can be achieved in a rather straight forward way by virtue of Standard ML module system. In order to evaluate the result of our type system implementation, we present the instantiation of two typed psi-calculus examples using the typed version of the Psi-calculi Workbench.

Resumo: A proposta do presente trabalho é articular um estudo comparativo entre o romance Lavoura Arcaica, de Raduan Nassar (1975), e o filme homônimo, LavourArcaica de Luiz Fernando Carvalho (2001). Atualmente, não podemos mais negar a influência das diversas formas de arte na vida moderna, principalmente, do cinema. A literatura influencia o cinema e o cinema a literatura. Mesmo sendo meios diferentes, há ressonâncias entre eles e que podem ser vistas até como obras complementares na medida em que há a possibilidade de serem analisadas uma com o auxílio da outra. Além das interseções que existem entre as diferentes formas de arte que já são por si só delicadas, há dificuldades que permeiam a majestade e complexidade dessas obras e, por isso, deparamo-nos, desde sempre, com questões do tipo: como falar sobre e mesmo absorver obras tão intensas? Como desvendar os mistérios dessas obras sem deturpá-las ou reduzí-las? Para tanto, nessa pesquisa, fizemos uso de alguns conceitos que mesclam a teoria da literatura, a teoria cinematográfica e a psicanálise de Freud e Lacan, principalmente; para que, assim, pudéssemos articular um estudo que fosse ao mesmo tempo "severo" e que preservasse os interstícios fundamentais e a poesia das obras.
Abstract: The proposal of this work is to articulate a comparative study between the romance To the left of the father, Nassar Raduan (1975), and the film, To the left of the father by Fernando Carvalho (2001). Today, we can no longer deny the influence of various forms of art in modern life, mainly of cinema. Literature influences the cinema and cinema, literature. Although they are different art forms, movie and romance can be seen as complementary works to the extent that there is the possibility of analising one on behalf of the other. In addition to the delicate intersections that exist between the various forms of art, there are difficulties which permeate the majesty and complexity of such works and therefore questions always turns up: how to talk about and even absorb so intense works? How to unravel the mysteries of such works without distort or reduce them? To do this research we use some concepts that merge into the theory of literature, film and, mainly, Freud's and Lacan's theorys of psychoanalysis; so that, by these means, we could articulate a study that is at the same time "severe" and that preserves the fundamental interstices and both work's poetry.

O estudo etnográfico está centrado na mudança nas relações geracionais da agricultura familiar do Município de Quilombo, Oeste de Santa Catarina, precisamente nas famílias cujos filhos passaram pela Casa Familiar Rural Santo Agostinho. A pesquisa parte da idéia inicial de que o saber do pai, central para a legitimidade da autoridade paterna na organização familiar tradicional, está sendo questionado quanto a sua eficiência para reproduzir a família. A interferência do processo educativo da Casa Familiar Rural, ao proporcionar uma troca de saberes que introduz a possibilidade de manutenção e, talvez, ampliação do patrimônio familiar, propicia aos jovens uma certa autoridade. O resultado é a construção de espaços de diálogo entre a autoridade fragmentada do pai e as autoridades múltiplas, tecendo um novo território familiar.

A figura do pai, até os anos 60 era pouco expressiva no desenvolvimento infantil. A maioria das pesquisas concentram seus estudos nas características da interação mãe-bebê, cabendo ao pai, a responsabilidade apenas pelo sustento familiar. A partir de resultados de estudos que comprovaram a importância do papel dos pais no desenvolvimento social e afetivo do bebê, inverteu-se esse quadro. No entanto, no Brasil são raros os estudos que se dirigem a este ponto. Assim, esta pesquisa teve como objetivo analisar as interações pai-bebê em contextos específicos. Foi realizado o registro em vídeo, em ambiente natural, de três díades em quatro momentos de desenvolvimento: 1, 2, 3, 4 mês de idade de bebês entre 30 dias a 5 meses, onde foram analisados os episódios de domínio social, domínio didático e interação não efetivada, além de registrar alguns relatos dos pais sobre os aspectos gerais da situação e acontecimentos relevantes. Após 05 meses foi realizado um encontro final, examinando a experiência do pai, sua participação no desenvolvimento do filho, bem como, o depoimento das mães quanto a sua participação. Concluindo, foram identificadas interações iniciais como processos recíprocos de engajamento que tornaram-se mais freqüentes e complexas no decorrer dos meses, com o predomínio de episódios de domínio didático, além do prazer dos pais em participar dos cuidados dos filhos, mediados por uma atitude de amor paterno.

This thesis has been written at Ericsson AB in Kumla. The purpouse of the thesis was to evaluate if it was possible to use PXI instruments in Ericsson’s current test system and if it would bring any improvements. The parameters considered were compatibility, test time, radio frequency performance, equipment footprint and total cost of ownership. Compatibility and test time was evaluated using small test apps, the other three evaluations are based on calculations. We found that PXI is compatible with Ericsson’s current test system, is faster than the current instruments, has similar radio frequency performance stats, does not change equipment footprint and shows a 6 % cost decrease in total cost of ownership.

Tesis por compendio de publicacionesIt is well known that Takahashi's Theorem [7] characterizes the submanifolds in the Euclidean space whose coordinate functions are eigenfunctions of the Laplacian associated to the same nonzero eigenvalue: they are minimal submanifolds in a hypersphere. Later on, many authors have obtained different extensions of Takahashi's Theorem. One of these extensions is given by Dillen-Pas-Verstraelen in [2]. In that work, the authors study surfaces in the 3-dimensional space whose immersion ψ satisfy Δψ=Aψ+b, where Δ denotes the Laplacian operator, A is a 3x3 real matrix and b is a constant vector. They obtain that the only surfaces satisfying that equation are minimal ones, spheres and circular cylinders. After that different authors have studied this condition in the case of hypersurfaces Mn immersed in pseudo-Euclidean spaces Rn+1 for any index t≥0, and showed that Mn must be an open part of a minimal Rn+1 surfaces, a totally umbilical hypersurface or a standard pseudo-Riemannian product. Recently, that equation has been extended to operators different to the Laplacian one. In fact, Alías and Gürbüz study in [2] hypersurfaces in the Euclidean space Rn+1 whose position vector ψ satisfies Lkψ=Aψ+b, where Lk is the linealized differential operator associated to the mean curvature of order k+1, for k=0, 1,..., n-1 (note that for k=0 we obtain the Laplacian operator). Those authors show that the only hypersurfaces satisfying the above condition are k-minimal hypersurfaces, hyperspheres and generalized cylinders (for appropriate radii and dimensions). In view of that result for operators Lk, we study the same condition but for hypersurfaces immersed in pseudo-Euclidean spaces Rn+1 for any index t≥0, and show (in papers [5] and [6]) that the only hypersurfaces in the pseudo-Euclidean spaces satisfying that condition are k-minimal hypersurfaces, hyperspheres and generalized cylinders (for appropriate radii and dimensions). After solving the problem for hypersurfaces in pseudo-Euclidean spaces, we study the condition Lkψ=Aψ+b for hypersurfaces immersed in pseudo-Riemannian space forms, for arbitrary index t≥0 and nonzero constant curvature. We show (in papers [3] and [4]), that the only hypersurfaces satisfying that condition are k-minimal hypersurfaces, totally umbilical hypersurfaces, standard pseudo-Riemannian products and some quadratic hypersurfaces. In conclusion, the results obtained in this Thesis extend completely to pseudo- Euclidean spaces and pseudo-Riemannian space forms of nonzero constant curvature the results previously obtained in [2].

Full textAbstract:
This research takes an interdisciplinary approach and includes aspects of applied geography, applied management, political economy, development studies, sociology and anthropology, in line with the tradition of progressive tourism studies. It seeks to resolve academic concern about the limited insight within existing bodies of knowledge into how sustainability and sustainable tourism development are conceptualised at a grassroots level by inhabitants and other stakeholders of tourism destinations (Redclift, 1987; Liu, 2003; Swarbrooke, 1999; Mowforth and Munt, 1998; Maida, 2007) and furthermore how these conceptualisations are shaped through expressions of political economy in a post-crisis context. The research aimed to evaluate how political economy and interpretations of sustainability affected post-disaster tourism redevelopment using the case study of Phi Phi Island in Thailand, which was devastated by the tsunami of December 2004. An interpretive philosophy informed the research design, in which primary data was gathered using an inductive mixed methodology. Methods included online research, comprising the design and operation of a tailored website to overcome geographical and access limitations; and offline methods such as visual techniques to monitor change and confirm opinions offered by participants of the research; in-depth face-to-face interviews with hand-picked stakeholders of Phi Phi's development; open-ended questionnaires with tourists; and extended answer Thai script questionnaires in order to overcome language barriers and present the 'Thai voice'. The primary data was gathered from April 2006-December 2011 including a period working at [information removed for anonymity purposes] University in Phuket (June-December 2006). Twenty-five themes emerged from the data, the most significant being the social impacts of tourism, environmental impacts of tourism, power relationships and future desires. It was found that the factor with the greatest influence over Phi Phi's development is the desire to develop the economy through tourism, and the philosophy underpinning the development is largely economic. The tsunami did not cause any significant reassessment of the tourism development trajectory, but served to uncover a range of conflicts and unlawful activity, resulting from powerful stakeholders pursuing their own interests and desired outcomes, in order to suit their own needs rather than those of the community as a whole. In terms of how sustainability is conceptualised by different stakeholder groups, it was found that the meanings attributed to sustainability in this context differ greatly to meanings elaborated within western ideological debates. Stakeholders' conceptualisations of sustainability were mapped against key debates within literature. How meanings differed between stakeholder groups was also examined and a definition for sustainable tourism development on Phi Phi was compiled encompassing a broad range of interests. The thesis provides a rare opportunity to see which political, economic and cultural factors shape the planning of tourism development and whether actual practice mirrors the principles of sustainability. For islanders, present needs are yet to be met and education was recommended to increase islanders' understanding of impacts and sustainability, as well as their skills and knowledge base to enable them to compete intellectually with the ruling elite and reduce dependence upon landowners and the mainland. Numerous authors have highlighted a relative lack of academic attention directly addressing the influence of political economy on achieving sustainability in post-disaster reconstruction (Klein, 2008; Hystad and Keller, 2008; Olsen, 2000; Bommer, 1985; Beirman, 2003; Faulkner, 2001; Glaesser, 2003; Ritchie, 2004). This work therefore extends existing academic debates and studies in a number of areas. In existing academic debates concerning the political economy of post-disaster reconstruction there is a trend towards 'disaster capitalism' (Klein, 2005: 3) or 'smash and grab capitalism' (Harvey, 2007: 32) and 'attempts to accumulate by dispossession' (Saltman, 2007a: 57). However, this did not occur on Phi Phi. Despite claims of a 'clean slate' being offered by the tsunami in developmental terms (Pleumarom, 2004; UNDP, 2005; Dodds, 2011; Ko, 2005; Nwankwo and Richardson, 1994; Argenti, 1976; Rice, 2005; Altman, 2005; Brix, 2007; Ghobarah et al., 2006; Dodds et al., 2010), this research provides evidence and explanation of why this did not and would never exist on Phi Phi, a finding that may be applied to other destinations in a post-disaster context. In response to Blaikie et al.'s (2004) concerns that vulnerability is often reconstructed following a disaster and may create the conditions for a future disaster, this work has extended discussions of disaster vulnerability through an adapted application of Turner et al.'s (2003) Vulnerability Framework. This meets Calgaro and Lloyd's (2008) recommendation that further longitudinal research is required in other tsunami-affected locations. This research refines their work to identify a detailed framework of vulnerability factors intertwined with factors of political economy, presenting a post-disaster situation that remains highly vulnerable and non-conducive to sustainability. This is in response to Hystad and Keller's (2008) recognition that there is a lack of long-term studies, which not only show how disaster has shifted the nature of the destination and tourism product, but also identify successful strategic processes and actions in disaster response. The strategic response has been analysed through an adapted Strategic Disaster Management Framework (Ritchie, 2004) to identify the shortcomings of the disaster response to comprehend how such a disaster has influenced tourism development and planning on the island, showing that this was a mirror opposite to how a disaster should be handled according to the literature (Ritchie, 2004; Adger et al., 2005; Miller et al., 2006; Olsen, 2000; Coppola, 2007; Faulkner, 2001; Baldini et al., 2012). The researcher draws on the notion of 'strategic drift' (Johnson, 1998: 179) and 'boiled frog syndrome' (Richardson, Nwankwo and Richardson, 1994: 10) to explain how host attitudes to tourism may increase vulnerability. Both these contributions can assist in identifying destination vulnerability and limitations in disaster response and recovery. Unlike the work of Dodds (2010) and Dodds et al. (2011), the aim was not to assess the practice and attainment of sustainability on Phi Phi; rather, it was to elaborate interpretations and conceptualisations of sustainability. An examination of development philosophy established how specific factors of political economy and relationships of a hegemonic nature influence the development trajectory of both Phi Phi and Thailand. Despite governmental rhetoric influenced by a strong 'sufficiency economy' hegemony led by King Bhumibol Adulyadej, the observations of dependency theorists provide a better fit for the experiences on Phi Phi and present significant challenges for the pursuit of sustainability. The thesis posits that an effective response to the disaster and pursuit of sustainability are undermined by the political economy of the destination.

Full textAbstract:
Background- Coronary Heart Disease (CHD) is one of the leading causes of death and disability worldwide. Revascularisation of the coronary arteries using Percutaneous Coronary Intervention (PCI) has become the treatment of choice for most of the patients with CHD. Despite significant advances in angioplasty technique and introduction of anti-proliferative medications in drug eluting stents, myocardial injury during PCI is still significant. In this thesis we hypothesised whether Remote Ischaemic Preconditioning (RIPC) can reduce PCI-related myocardial injury. Methods- Eighty-eight patients awaiting elective complex PCI were randomly assigned in a 1:1 ratio to receive either the RIPC (intermittent arm ischaemia and reperfusion through four cycles of 5-minutes inflation and 5-minutes deflation of a blood-pressure cuff placed on the upper arm) or control (un-inflated cuff placed on upper-arm for 40 minutes) prior to PCI. The primary endpoint was reduction of the incidence and extent of PCI-related myocardial injury, assessed by serum cardiac biomarkers, 24 hours post PCI. Results- The Troponin T level at 24 hours post PCI was 48 ng/l in the control group vs 32.5 ng/l in the RIPC group, P = 0.39. There was no significant reduction in the total area under the curve (AUC) in the RIPC group, P= 0.43. Regarding the incidence of PCI-related myocardial injury, significant elevation of Troponin level post PCI (> 5 x baseline), was observed in 46.9% of patients in the control group and in 26.7 % of patients in the RIPC group, p =0.12. Conclusion- In the ERIC-PCI study, RIPC did not demonstrate a statistically significant attenuation of serum Troponin release post PCI. The results however showed a positive trend towards efficacy of RIPC in reducing PCI-related myocardial injury.

Nous sommes partis d'une analogie inédite entre la configuration de certaines feuilles dans le bourgeon et les ribambelles de papier. Quand on plie du papier et qu'on le coupe avec des ciseaux, à chaque pli va correspondre une pointe ou un creux de la ribambelle déployée. De nombreuses feuilles adoptent la même géométrie dans le bourgeon. Le bord de la feuille est replié sur un plan comme si il avait été découpé avec des ciseaux. Pour cette raison purement géométrique, les lobes et creux de la feuille déployée correspondront exactement aux plis initiaux. Nous avons nommé ces feuilles « kirigami », ce qui veut dire couper-papier en japonais. La première partie de cette thèse, purement géométrique, montre à quel point les géométries des feuilles sont contraintes par leur développement plié. Nous montrons aussi que la richesse des géométries que permet le kirigami se retrouve au sein des feuilles. La deuxième partie, plus biologique, propose à la fois un mécanisme pour le développement des plis et un candidat pour les mystérieux ciseaux. Nous concluons sur l'intérêt évolutif d'une telle organisation des feuilles dans le bourgeon.
