A P-3 Scheduling Support System (P-3 S3) is a Management Information System (MIS) that was designed using structured techniques. Structured analysis was used to determine the functionality and data requirements. Computer Assisted Systems Engineering (CASE) tools were used to document the analysis and design. The system was designed to be implemented in dBase III Plus, a data base management tool developed by Ashton Tate. P-3 S3 is designed to run on a microcomputer with the MS-DOS operating system. It provides real-time access to historical data and provides suggested personnel assignments to the user. The design provides for faster flight schedule generation and prevention of conflicting schedule events. Keywords: software development; patrol squadrons; theses

Esta tese envolveu a síntese de 11 precursores poliméricos inéditos, derivados de bifenilos e terfenilos, substituídos por grupos receptores e doadores de elétrons, por meio de reações de acoplamento de Suzuki. Tais precursores foram convertidos aos respectivos polímeros, poli(p-xilileno)s e poli(p-fenileno vinileno)s, via redução catódica, conduzindo a um total de 11 polímeros, sendo dez deles inéditos. Os polímeros obtidos foram caracterizados por métodos espectroscópicos (UV-VIS, IV, RMN), análises térmicas, SEC e medidas de condutividade elétrica pós-dopagem. Um dos polímeros foi empregado na construção de dispositivos metal/polímero/metal (\"sanduíche\"), que permitiram a determinação da mobilidade dos portadores de carga, bem como da altura de barreira para injeção de elétrons na junção metal/polímero.The synthesis via Suzuki coupling reaction of 11 new biphenylenic and terphenylenic polymer precursors, substituted by long-chain electron donating or withdrawing groups, is described. The electrochemical reduction of these precursors led to the corresponding poly(p-xylylene)s and poly(p-phenylene vinylene)s. Ten out of the 11 generated polymers have been never described before. AII the polymers were fully characterised by spectroscopic (UV-VIS, IR, NMR) and thermal analyses, as well as by SEC and electrical conductivity measurements of iodine-doped specimens. The positive charge carrier mobility and the barrier height for electron injection (metal/polymer) could be determined through I x V investigations of sandwich devices (metal/polymer/metal) for one of the polymers.

Previous issue date: 2006-03-31The present work was carried out in three different goat raisings and 27 females and 2 males were selected for identifying the present microbiota in the preputial and vaginal cavity of goats under three estrous cycle phases: In Februrary, 2005 in the pro-estrum, in May, 2005 in the post-copula and in October, 2005 in the post-partum. The samples were collected by swabs as well as vaginal and preputial washings for studying microbiota and by gynecological brushes for the females esfoliative cytological study. The two greatest bacteria genera prevalence were: Micrococcus spp (89,65 %) following by Bacillus spp. (29,90 %). Filamentous fungi as Cladosporium spp. (26,39 %) and Aspergillus spp. (11,46 %) were the most isolated. On the bacteria cytological test about 76 % of the investigations have been in accordance with the microscopic finding and bacteria isolation. In 89% appraised animal some yeasts presence on sheets was observed in spite of there was isolation just in 7,4 % of the animals. There was similarity between hifas observation and filamentous fungi isolation, in regarding to 53 % of hifas presence investigations. The bacterial and fungical microbiota found on this survey showed the goats vaginal and preputial microbiota diversity and pointed out to the fact that it might be carried during copulation. The number of isolated bacteria species in the post-copulation phase was upper, as well as for yeasts. The vaginal cytology performed significative association in relation to the bacterial isolation, observed by cocos and bacilli presence on the sheets with positive growth. Bacteria potentially pathogenic as Pseudomonas alcalinigenes, P. aeruginosa, and Corynebacterium spp. as well as opportunist fungi as Aspergillus flavus in healthy goats vaginal cavity were found.
O presente trabalho foi desenvolvido em tr?s criat?rios caprinos distintos, de onde tomamos 27 f?meas e 2 machos a fim de identificar a microbiota presente no prep?cio de bodes e na cavidade vaginal de cabras em tr?s fases do ciclo estral: fevereiro de 2005 no proestro, maio de 2005 ap?s a c?pula e outubro de 2005 ap?s o parto. As amostras foram coletadas atrav?s de swab, lavado vaginal e prepucial para o estudo da microbiota e com escovas ginecol?gicas para o estudo colpocitol?gico das f?meas. Os dois g?neros de bact?rias de maior preval?ncia foram os seguintes: Micrococcus spp. (89,65 %) e Bacillus spp. (29,90 %). Os dois g?neros de fungos de maior preval?ncia foram Cladosporium spp. (26,39 %) e Aspergillus spp. (11,46 %). No estudo colpocitol?gico para bact?rias, em 76 % das investiga??es houve concord?ncia entre os achados microsc?picos e isolamento bacteriano. Em 89 % dos animais avaliados foi observada a presen?a de leveduras nas l?minas, mas houve isolamento em apenas 7,4 % dos animais. Em 53 % das investiga??es da presen?a de hifas houve concord?ncia entre a observa??o de hifas e o isolamento de fungos filamentosos. A microbiota f?ngica e bacteriana encontrada no presente trabalho evidenciou a diversidade da microbiota vaginal e prepucial de caprinos e aponta para o fato de que podem ser carreados durante a c?pula. Observou-se que o n?mero de esp?cies isoladas de bact?rias ? superior na fase de p?s-c?pula enquanto que em fungos observamos este aumento no p?s-parto; O resultado da citologia vaginal teve correla??o com o isolamento bacteriano, observada pela presen?a de cocos e bacilos nas l?minas com crescimento bacteriano positivo; Bact?rias potencialmente patog?nicas como Pseudomonas alcaligenes, P. aeruginosa e Corynebacterium spp. foram encontrados na cavidade vaginal de cabras h?gidas, assim como fungos oportunistas como Aspergillus flavus.

Previous issue date: 2007-01-10Na presente pesquisa foi estudado o mang? como um meio de comunica??o, evidenciando suas caracter?sticas modernas e p?s-modernas atrav?s de suas imagens. As imagens dos mang?s hist?rias em quadrinhos japonesas foram analisadas a partir das perspectivas moderna e p?s-moderna, passando por sua defini??o e hist?ria para a efetiva an?lise de suas formas simb?licas, nelas encontrando, caracter?sticas plurais e h?bridas, comuns ? condi??o p?s-moderna, bem como valores claros entre bem e mal, como aqueles presentes na modernidade. Neste contexto, buscaram-se refer?ncias que entendam e valorizem o mang? como meio de comunica??o e gerador de novas possibilidades de reflex?es e conhecimentos visuais. Trata-se de um estudo qualitativo e descritivo, que se baseia numa metodologia de interpreta??o hermen?utica sugerida por Thompson (1995). Al?m da revis?o te?rico-bibliogr?fica, este trabalho apresenta a an?lise de depoimentos de leitores de mang? para um melhor entendimento do motivo de consumo deste no Brasil. Os depoimentos foram coletados sob a forma de entrevista despadronizada em profundidade, conforme indicada para a pesquisa qualitativa por Bardin (1977). As entrevistas ocorreram individualmente, e foram analisadas com o enfoque da hermen?utica de profundidade, de acordo com Thompson (1995). O conjunto de entrevistados constituiu-se de sete sujeitos, sendo tr?s estudantes universit?rios, uma estudante com Ensino M?dio completo e tr?s estudantes de Ensino M?dio. Todos os entrevistados encontravam-se na faixa et?ria entre 15 e 25 anos. A an?lise dos dados coletados evidenciou que o mang? ? capaz de comunicar, mesmo sendo produto de uma cultura oriental notoriamente diferente da ocidental na qual vivemos. O trabalho evidencia tamb?m, que os mang?s cont?m caracter?sticas tanto modernas quanto p?s-modernas, sendo assim duvidoso afirm?-lo como moderno ou p?s-moderno.

Testo completoAbstract (sommario):
Dans les collèges de l'enseignement secondaire français, les élèves en grande difficulté scolaire peuvent être pris en charge dans les Sections d'Education Spécialisée. L'éducation physique et sportive est l'une des disciplines qui y sont enseignées. Elles est confiée à des instituteurs qui enseignent toutes les matières ou à des professeurs qui n'enseignent que l'Éducation Physique et Sportives dans les établissements du second degré. Tous se voient confié les mêmes objectifs éducatifs, ce qui n'impose pas la reconnaissance d'une même identité professionnelle. Une enquête a été menée, en 1994-95, dans les deux académies de Lyon et Grenoble. Les valeurs partagées pouvant structurer un groupe ont été étudiées, suivant le schéma de repérage préconisé par Claude DUBAR. Pour chacun des deux groupes d'enseignants, les cultures sportives personnelles actuelles sont peu différentes, les pratiques anciennes et la formation très différenciées. Chacun des groupes souhaite que la formation apporte à l'autre groupe les connaissances ou outils qu'il estime posséder seul lui-même. Une unification des formations est demandée. Dans sa propre représentation des élèves de Section d'Éducation Spécialisée, chaque groupe traduit une très forte implication professionnelle. Les valeurs partagées restent caractéristiques du groupe des instituteurs ou du groupe des professeurs. Elles ne suffisent pas à définir une identité professionnelle commune.

Esta compilación de ensayos reúne la mayoría de mis escritos sobre derecho y teoría contractual que han sido publicados en revistas académicas a lo largo de un período de casi 20 años. Reunir estas piezas me ha permitido ver muchas relaciones que antes se me habían escapado e incluso si hoy tengo menos seguridad de algunas de las respuestas que antes, tengo (creo) mayores certezas acerca de la naturaleza de algunas de las preguntas fundamentales. Todos los ensayos han sido actualizados y revisados, algunos muy sustancialmente, y existen varias secciones completamente nuevas.

Previous issue date: 2009-05-07Este trabalho se prop?e a fazer uma demonstra??o gen?rica da influ?ncia da cultura p?s-moderna na Igreja enquanto institui??o s?lida, sacramental, de Tradi??o coletiva. Mostra que o homem da p?s-modernidade se contrap?e a tr?s dos aspectos essenciais do que ? Igreja, pois este ?: relativista, subjetivista e individualista, al?m de voltado para si mesmo. Tal cultura exerce uma influ?ncia na Igreja por meio da consci?ncia de seus membros que ? formada por aquela numa rela??o dial?tica. Sendo assim a consci?ncia dos membros, - subjetivista, individualista e narc?sica, - causam dano ? Institui??o por quebrarem sua plausibilidade perante o povo e perante os pr?prios membros. A falta de plausibilidade causa perda da coes?o e da legitima??o. Esse ? o motivo da crise da Igreja Cat?lica Romana. A solu??o est? na forma??o, em que pode haver uma retifica??o da consci?ncia e da raz?o, que foi deformada pela modernidade e p?s-modernidade.

This study aimed to assess factors associated with nipple trauma in women who breastfeed, resulting in two articles. The first entitled "Factors associated with nipple trauma in lactation period: a systematic review" was based on the search of publications indexed in the databases Medical Literature Analysis and Retrieval System Online/Pubmed, Latin American and Caribbean Health Sciences, and ScienceDirect, with no restriction on language or publication period. As risk factors for nipple trauma were identified: mother with white or yellow race/color, primiparity, cracked nipples in previous pregnancies, mother who does not live with a partner, use of anesthesia in parturition, gestational age of the newborn between 37 to 40 weeks, presence of breastfeeding in the first hour of life, semi protrude and/or malformed nipples, malposition between mother and child, incorrect lacth of the infant in mother's breast, presence of breast engorgement, nipple pain, use of nursing bottle, use of pacifier and lactational mastitis. On the other hand, the guidance received about how to lacth and positioning the infant in the maternal breast during prenatal was considered as a protective factor against the nipple trauma. The second article entitled "Nipple fissure: study of latent variables in the first month postpartum" consisted of a cross-sectional analysis of a birth cohort, an observational and prospective character, who studied the mother-child dyad. The prevalence of cracked nipples observed in mothers who breastfeed in the first month postpartum was 35.9%. It was found among the latent variables that the unfavorable maternal emotional state (OR= 1.65; 95% CI= 1.26-2.16) and lower availability for breastfeeding (OR= 1.80; 95% CI= 1.25-2.59) were associated with cracked nipples, as well as the covariates parturition in unit that is not recognized as a Baby Friendly Hospital (OR= 1.48; 95% CI= 1.07-2.03), cesarean section (OR= 1.72; 95% CI= 1.33-2.24) inadequate positioning of the newborn during breastfeeding (OR= 3.91; 95% CI= 1.02-14.99), incorrect lacth of the infant the in the maternal breast (OR= 14.36; 95% CI= 7.80-26.46) and the presence of breast engorgement (OR= 2.74; 95% CI= 2.10-3.58). Preventive measures against the risk factors of nipple trauma are necessary to prevent this important cause of pain during breastfeeding and premature weaning.
Este estudo teve como objetivo avaliar os fatores associados ao trauma mamilar em lactantes, tendo como resultado dois artigos. O primeiro intitulado ?Fatores associados ao trauma mamilar no per?odo lactacional: uma revis?o sistem?tica? foi fundamentado na busca de publica??es indexadas nas bases de dados Medical Literature Analysis and Retrieval System Online/Pubmed, Literatura Latino-Americana e do Caribe em Ci?ncias da Sa?de, e ScienceDirect, sem restri??o de idioma ou per?odo de publica??o. Foram identificados como fatores de risco para o trauma mamilar: m?e de ra?a/cor branca ou amarela, primiparidade, presen?a de fissura mamilar em gesta??es anteriores, m?e n?o residir com o companheiro, uso de anestesia no parto, idade gestacional do rec?m-nascido entre 37e 40 semanas, presen?a de mamada na primeira hora de vida, mamilos semiprotrusos e/ou mal formados, posicionamento inadequado entre m?e e filho, pega incorreta do lactente ao seio materno, presen?a de ingurgitamento mam?rio, dor mamilar, uso de mamadeira, uso de chupeta e mastite lactacional. Por outro lado, a orienta??o recebida sobre pega e posicionamento do lactente ao seio materno durante o pr?-natal foi considerada como fator de prote??o contra o trauma mamilar. O segundo artigo intitulado ?Fissura mamilar: estudo de vari?veis latentes no primeiro m?s p?s-parto? consistiu em uma an?lise transversal de uma coorte de nascidos vivos, de car?ter observacional e prospectiva, que estudou a d?ade m?e-filho. A preval?ncia de fissura mamilar observada em lactantes no primeiro m?s p?s-parto foi de 35.9%. Verificou-se entre as vari?veis latentes que o estado emocional materno desfavor?vel (OR= 1.65; IC 95%= 1.26-2.16) e menor disponibilidade para amamentar (OR= 1.80; IC 95%= 1.25-2.59) associaram-se ? fissura mamilar, assim como as covari?veis parto em unidade n?o credenciada como Hospital Amigo da Crian?a (OR= 1.48; IC 95%= 1.07-2.03), parto ces?reo (OR= 1.72; IC 95%= 1.33-2.24), posicionamento inadequado do neonato durante a mamada (OR= 3.91; IC 95%= 1.02-14.99), pega incorreta do lactente ao seio materno (OR= 14.36; IC 95%= 7.80-26.46) e presen?a de ingurgitamento mam?rio (OR= 2.74; IC 95%= 2.10-3.58). A??es de preven??o contra os fatores de risco do trauma mamilar s?o necess?rias para evitar esta importante causa de dor durante a mamada e de desmame precoce.

Previous issue date: 2013-01-25Individuals who are exposed to traumatic events and develop Posttraumatic Stress Disorder (PTSD) might present psychological, behavioral and cognitive difficulties after being exposed to trauma. Symptoms of PTSD include reexperience of the traumatic event, avoidance of stimuli related to the trauma and increased excitability. Regarding cognitive impairments, in addition to impairment in episodic memory and attention, PTSD has also been associated with impairments in executive functions. The impairments are not associated only with the formal diagnosis of PTSD and were also identified in individuals with high symptomatology of the disorder. This study aims to investigate cognitive performances on measures of executive functions in individuals with PTSD symptoms. For this, two studies were conducted, one theoretical and one empirical, presented in form of articles. The theoretical article sought to establish an overview of executive impairments shown by individuals exposed to trauma with either formal diagnoses of PTSD, history of PTSD or PTSD symptoms through a systematic review. The empirical article aimed to assess the cognitive performance of 29 subjects exposed to trauma and high scores on SPTSS inhibition, working memory and cognitive flexibility symptoms. These individuals had their performances compared to 24 individuals who were never exposed to any traumatic event, matched in age and education. Considering the high prevalence of disorders presented in comorbidity with PTSD the control group was formed by individuals who were being treated for any psychological or psyquiatric disorder other than PTSD. The control group consisted of clinical population because the presence of other psychopathologies can cause impairments on executive function. PTSD symptoms were assessed with the Screen for Posttraumatic Stress Symptoms (SPTSS), that aims to identify reexperience, avoidance and increased excitability symptoms in individuals exposed to trauma. A descriptive study with cross-sectional design was conducted. The group with individuals exposed to trauma and high PTSD symptoms showed poorer performance on Trail Making Test (p=0,009), an instrument used to assess cognitive flexibility. These impairments can lead to difficulties in adopting new cognitive strategies needed to deal with cognitive and environmental triggers that lead to the memory of the traumatic event. Only impairments in cognitive flexibility were identified, suggesting that some but not all EF components are affected by PTSD
Indiv?duos que experienciam um evento estressor traum?tico e desenvolvem Transtorno de Estresse P?s-traum?tico (TEPT) podem apresentar dificuldades psicol?gicas, comportamentais e cognitivas decorrentes da exposi??o ao trauma. Entre os principais sintomas do TEPT destacam-se a reviv?ncia do evento traum?tico, a esquiva de est?mulos relacionados ao trauma e a excitabilidade aumentada. No que se refere aos preju?zos cognitivos, al?m dos preju?zos na mem?ria epis?dica e na aten??o, o TEPT tem sido associado a preju?zos no funcionamento executivo. Esses preju?zos n?o s?o associados apenas ao diagn?stico formal de TEPT, sendo, tamb?m, identificados em indiv?duos com alta sintomatologia do transtorno. O objetivo geral deste estudo foi investigar o desempenho cognitivo em medidas de Fun??es Executivas (FE) de indiv?duos com elevada sintomatologia p?s-traum?tica de TEPT. Para isso, foram realizados dois estudos, um te?rico e um emp?rico, apresentados na forma de artigos. O artigo te?rico busca estabelecer, atrav?s de uma revis?o sistem?tica, um panorama geral dos preju?zos executivos apresentados por indiv?duos expostos a traumas com sintomas e diagn?stico formal atual ou passado de TEPT. O artigo emp?rico tem como objetivo avaliar o desempenho cognitivo de 29 indiv?duos expostos a traumas e com elevada sintomatologia p?s-traum?tica em medidas de inibi??o, flexibilidade cognitiva e mem?ria de trabalho. Esses indiv?duos tiveram seu desempenho comparado com o de 24 controles n?o expostos a nenhum evento traum?tico, pareados em rela??o ? idade e escolaridade. J? que indiv?duos com TEPT frequentemente apresentam outros transtornos em comorbidade, os controles inclu?dos tamb?m estavam em tratamento psicol?gico ou psiqui?trico para outras psicopatologias. Dessa forma, buscou-se observar poss?veis altera??es de desempenho cognitivo que n?o se devessem simplesmente ? exist?ncia de um transtorno, mas especificamente ao TEPT. Os sintomas de TEPT foram avaliados atrav?s do Instrumento de Rastreio de Sintomas de Estresse P?s-traum?tico (SPTSS), que tem como objetivo identificar sintomas de reviv?ncia, excitabilidade aumentada e esquiva em indiv?duos expostos a traumas. A pesquisa realizada foi descritiva, com delineamento do tipo transversal. O grupo composto por indiv?duos expostos a traumas e com alta sintomatologia de TEPT apresentou pior desempenho no Trail Making Test (p=0,009) instrumento utilizado para avalia??o da flexibilidade cognitiva. Esses preju?zos podem conduzir a dificuldades na ado??o de novas estrat?gias cognitivas necess?rias para lidar com os gatilhos ambientais e cognitivos que remetem ao evento traum?tico. Os resultados indicam que preju?zos em um ou mais componentes das FE podem estar associados aos sintomas de TEPT.

Previous issue date: 2011-02-08The study of Brazilian sedimentary basins concentrates on their rift phase, whereas the Post-rift phase has been considered a tectonic quiescent period. The post-rift sequence of the Potiguar Basin, in the far northeastern Brazil, was once considered little deformed, however several studies have shown how that it was affected by major fault systems. The purpose of this thesis is to characterize the post-rift tectonic. The specific objectives are: to characterize the Neogene and Quaternary sedimentary units that outcrop of the Potiguar Basin; to show how the NW-SEtrending Afonso Bezerra Faults System deformed outcrop rocks in the Basin; to describe soft-sediment deformation in gravels of the Quaternary Alluvial Deposits from A?u River. Facies analyses, grain-size studies, luminescence dating, remote sensing, structural mapping, shallow geophysics (georadar), paleostress and petrography were carried out. The structural mapping and the georadar sections indicated that the Carnaubais and Afonso Bezerra fault systems formed fractures, silicified and non-silicified faults or deformation bands, affecting mainly the A?u, Janda?ra and Barreiras formations. The petrographic data indicate that the strong silicification resulted in a sealant character of the faults. Paleostress analysis indicates that two stress fields affected the Basin: the first presented N-S-trending compression, occurred from the Neocretaceous to the Miocene; the second stress field presents E-W-trending compression, acts from the Miocene to the present. It was verified once the Afonso Bezerra System Faults was reactivated in periods post-Campanian and affects all post-rift lithostratigraphic units of Potiguar Basin, including Quaternary sedimentary covers. The study about soft-sediment deformation structures indicates that they are similar in morphology and size to modern examples of seismically-induced deformation strutures in coarse sediments. TL and OSL ages indicate that sediment deposition and associated soft-sediment deformation occurred at least six times from ~352 Ka to ~9 Ka. Finally these studies demonstrate how recent is tectonics in the Basin Potiguar
Os estudos sobre as bacias sedimentares brasileiras se concentram em sua fase rifte, enquanto a fase p?s-rifte tem sido considerada um per?odo de pouca atividade. A sequ?ncia p?s-rifte da Bacia Potiguar, no extremo nordeste brasileiro, j? foi considerada pouco deformada, contudo, in?meros trabalhos v?m demonstrando como ela ? afetada por importantes sistemas de falhas. A finalidade geral desta tese ? caracterizar a tect?nica p?s-rifte na Bacia Potiguar. Os objetivos espec?ficos s?o: caracterizar as unidades sedimentares cenozoicas aflorantes e a tect?nica associada; evidenciar como o Sistema de Falhas de Afonso Bezerra deformou rochas aflorantes da Bacia; descrever deforma??o em sedimentos inconsolidados nos conglomerados dos Dep?sitos Aluviais quatern?rios do Rio A?u. An?lises de f?cies, estudos granulom?tricos, data??o por luminesc?ncia, sensoriamento remoto, mapeamento estrutural, geof?sica rasa (georadar), an?lises de paleotens?es e petrografia foram realizados. O mapeamento estrutural e as sec??es de georadar indicaram que os sistemas de falhas Carnaubais e Afonso Bezerra formaram juntas, falhas silicificadas e n?o-silicificadas e bandas de deforma??o, afetando principalmente as forma??es A?u, Janda?ra e Barreiras. Os dados petrogr?ficos indicam que a forte silicifica??o deu ?s falhas um car?ter selante. O estudo de paleotens?es indica dois campos de tens?es afetando a Bacia: o primeiro, com compress?o N-S, atuou do Neocret?ceo ao Mioceno; o segundo, com compress?o E-W, atua do Mioceno ao presente. Constatou-se que o Sistema de Falhas de Afonso Bezerra foi reativado em per?odos p?s-campanianos e afeta todas as unidades litoestratigr?ficas p?s-rifte da Bacia Potiguar, inclusive as coberturas quatern?rias. O estudo sobre deforma??o em sedimentos inconsolidados indica que esta ? similar na morfologia e no tamanho aos exemplos modernos de estruturas de deforma??o sismicamente induzida em sedimentos grossos. Idades por TL e LOE indicam que a deposi??o dos sedimentos e a deforma??o associada ocorreram pelo menos em seis eventos entre aproximadamente 352 Ka e 9 Ka. Enfim estes estudos demonstram qu?o recente ? a tect?nica na Bacia Potiguar

Testo completoAbstract (sommario):
Notre travail s'oriente sur une articulation en trois parties : tout d'abord, nous avons tenu à analyser la situation originale du Liban sous le mandat français et à étudier les structures laissées par la tutelle ainsi que le climat difficile qui existait au moment de l'indépendance. Cette analyse a également requis un passage en revue des différentes formations politiques. Il s'agit ici de présenter le terreau complexe sur lequel va germer un parti nouveau : le Parti Socialiste Progressiste. Dans une deuxième partie, nous analyserons le contexte sociopolitique et les conditions particulières qui ont présidé à la naissance du P. S. P. évidemment, le rôle de Kamal Joumblatt, leader druze, apparaît au premier plan. Celui-ci était issu d'une famille qui joua un rôle très important dans l'histoire du Liban. Enfin la troisième partie de notre travail nous amène à analyser le programme, l'organisation et l'action du P. S. P. , et sur le plan de la politique intérieure, et sur le plan international, de 1949 date de naissance du parti, à la crise de 1958. La structure du parti, son programme et ses performances électorales sont analysées ainsi que les positions du P. S. P. Vis-à-vis des grands événements de l'époque tels que la révolution égyptienne de 1952, la crise de suez en 1956 et la crise libanaise en 1958Our study is oriented into three parts: at first, we have stressed on analysing the original situation of Lebanon under the French mandate, and to study the structures left by its tutelage, as well as the difficult situation existing at the time of the independence. This analysis has requested a round-up of the different political formations. We will be presenting here the complexed context in which a new party is going to take root, the socialist progressive party. The second part, we will analyse the socio-political context and the specific conditions which have prevailed at the birth of the socialist progressive party. Obviously, the role of Kamal Joumblatt, Druze leader, appears in the limelight. Kamal Joumblatt comes from a family which has played a very important role in the history of Lebanon. Finally the third part of our study brings us to analyse the programme, the organisation, the activity of the P. S. P. On the internal and international political level since 1949, date of birth of the party, until the crisis of 1958. The structure of the party, its programme and electoral performances are analysed along with the positions of the P. S. P. Versus the big events of the moment, such as the Egyptian revolution of 1952, the Suez crisis in 1956, and the Lebanese crisis in 1958

Testo completoAbstract (sommario):
I denna rapport undersöktes S&P 500 Energy Index genom multipel regressionsanalys. Modellerframställdes genom regression och baserades på data hämtad från börsen. Modellerna angavs iprocentuell ändring respektive absolut ändring. Validitet för varje enskild kovariat testades och en risknivå avgjorde om en kovariat skulle inkluderas i modellen eller inte. Detta ledde till två modeller med bättre kurvanpassning till den givna mängd data över det valda energiindex. Målet med regressionsanalysen var att med given data framställa en kurvanpassning som bäst beskrevden valda regressorn. De tester som utfördes för relativa värden påvisade en korrelation mellan energiindex och kovariater för råvaror och större marknadsindex, medan för absoluta värden påvisades en korrelation mellan energ iindex och nästan samtliga kovariater. Vidare, volatilitet hanterades bättre än förväntat av modellerna, speciellt den absoluta modellen. Genom gående kunde de båda modellerna, sett till felens storlek, beskriva S&P 500 Energy Index väl genomvalda kovariater.

Testo completoAbstract (sommario):
In recent years there has been great interest in developing bidentate systems where only one of the atoms is phosphorus. Mixed P, O- and P, N- donor ligands have been extensively applied in catalysis and there is growing interest with respect to potential applications of P, S-ligands. This thesis reports on the synthesis and application of a range of substituted P, S-ligands and the catalytic results obtained are discussed. Chapter 2 describes the synthesis of several bidentate phosphinothiolate and -thioether (P, S) ligands. The P, S ligand l-(diphenylphosphino)butane-2-thiol (L1) was derived from a thiirane which was synthesised by the ring-opening reaction of an epoxide. The thioether tertiary-butyl derivative (L2) was also synthesised along with the thioether methyl (L3), thioether benzyl (L4), thioether xylene (L5), thioether naphthalene (L6) and thioether anthracene (L7). The ligands were subsequently coordinated to palladium and the resulting complexes (1-12) exhibit a monomelic or dimeric geometry. Chapters 3 and 4 detail the application of the palladium complexes in catalytic reactions. The palladium phosphinothiolate and -thioether complexes have been tested as pre- catalysts in the Heck and Suzuki cross-coupling reactions which were performed under aerobic conditions. The Heck couplings with styrene and butyl acrylate were investigated along with a variety of haloarenes, and the Suzuki reactions have explored the cross-couplings of various haloarenes with benzene boronic acid. The complexes tested were highly efficient catalysts in the coupling reactions. Turnover numbers (TONs) of up to 1 million have been achieved for Heck couplings and 1.98 x 1010 for the Suzuki coupling reactions.

This dissertation contains two empirical articles which investigated the communication skills and executive functions of adults with traumatic brain injury (TBI) upon hospital admission (inpatients) and after hospital discharge (outpatients). The aim of the first study was to compare discursive, pragmatic, lexical-semantic, reading and writing skills between inpatients with TBI (iTBI) and adults with no neurological damage. Our results showed between-group differences on all parameters evaluated, with control participants outperforming the iTBI group across all measures used in the study. The aim of the second investigation was to identify differences between outpatients with mild or severe TBI (oTBI) and healthy adults on communicative and executive functions, as well as to investigate associations and dissociations between patterns of impairment in the oTBI sample. The two groups differed in their performance on conversational and narrative discourse tasks, as well as on the following executive functions: planning, cognitive flexibility, working memory, processing speed and inhibitory control. Overall, the findings suggested that even subjects with relatively mild lesions and a theoretically good prognosis may experience impairments in discourse processing. The patient group was then further divided according to TBI severity, and differences in executive functions were identified between these two subgroups, as well as between each of these categories and the control group. Patients with severe TBI performed worse than control participants and subjects with mild TBI, and differences between patients with mild and severe TBI were identified in both studies. Lastly, the TBI groups showed dissociations between impairments in rule maintenance and processing speed, and associations between cognitive performance on planning tasks. These findings contributed to the current literature on the continuum of communicative and executive impairment profiles across all levels of TBI severity. The analyses performed in this dissertation may be used in public health services to perform a more accurate assessment of patients with TBI and improve prognostic accuracy, since some impairments may have an impact on global functioning and affect the length of the post-TBI recovery period.
A presente disserta??o de mestrado compreende dois artigos emp?ricos que pretendem explorar a avalia??o dos processamentos comunicativos e executivos de pacientes adultos com traumatismo cranioencef?lico (TCE) em dois momentos ap?s a les?o cerebral: no momento da interna??o (inpatients) e ap?s alta hospitalar (outpatients). O primeiro estudo objetiva comparar os processamentos discursivo, pragm?tico, l?xico-sem?ntico, de leitura e de escrita de pacientes adultos p?s TCE do tipo inpatients (TCEi), comparando o desempenho com indiv?duos sem les?o cerebral. Os resultados indicaram que os participantes se diferenciaram nos quatro processamentos comunicativos sendo que o grupo com TCE teve pior desempenho. O segundo estudo teve como objetivo verificar se existem diferen?as entre pacientes p?s-TCE - do tipo outpatients com gravidades leve e grave - e indiv?duos saud?veis, quanto ao desempenho nos processamentos comunicativos e executivos, al?m de identificar se associa??es e dissocia??es existem na amostra de TCE. Encontraram-se diferen?as entre grupos nos escores do discurso conversacional e narrativo e nas habilidades executivas de planejamento, flexibilidade cognitiva, mem?ria de trabalho, velocidade de processamento e inibi??o. Tais achados, de forma geral, indicam que pacientes com menor les?o e teoricamente melhor progn?stico, podem apresentar desempenho discursivo abaixo do esperado. Al?m disso, as tarefas indicaram diferen?as nas habilidades executivas entre os tr?s grupos. pacientes com TCE grave tiveram pior desempenho do que controles e pacientes com TCE leve, ainda TCE leve diferenciou-se dos graves nos dois estudos. Por ?ltimo, dissocia??es entre os grupos de TCE foram encontradas nos itens de manuten??o de regras e velocidade de processamento e associa??es encontradas nos itens de planejamento. Os resultados dos dois estudos emp?ricos contribuem para a comunidade cient?fica em entender um perfil cont?nuo de dificuldades mesmo em pacientes com o menor ?ndice de gravidade de les?o. As an?lises apresentadas nessa disserta??o de mestrado s?o poss?veis de serem implementadas nos servi?os p?blicos para avalia??o mais apurada desses pacientes e para identificar melhor progn?stico j? que algumas dificuldades podem afetar globalmente o funcionamento dos pacientes e dificultar, inclusive, o per?odo de recupera??o p?s les?o cerebral.

Testo completoAbstract (sommario):
Given an integer matrix A, there is a unique matrix S of a particular form, called the Smith Normal Form, and non-unique unimodular matrices P and Q such that PAQ = S. It is often the case that these matrices P and Q will be used for further calculation, and as such it is desirable to find P and Q with small entries. In this thesis we address the problem of finding such P and Q with small entries, in particular in the case where A is a diagonal matrix, which arises as a final step in many published algorithms. Heuristic algorithms are developed which appear to do well in practice and some theory is developed to explain this behaviour. We also give an account of the implementation of an alternative algorithm which bypasses this intermediary diagonal form. The basic theoretical development of this is work by Storjohan.

Ce travail concerne les extremes des suites gaussiennes stationnaires multivariees et des suites m-dependantes stationnaires. Il est compose de trois parties. La premiere partie (chapitre 1) est une synthese de certains resultats classiques dans la theorie des valeurs extremes pour des suites aleatoires i. I. D. Et stationnaires. Dans la deuxieme partie (chapitre 2), nous considerons une suite stationnaire m-dependante verifiant une certaine hypothese de dependance locale. Haiman (1987) a demontre qu'on peut construire sur le meme espace de probabilite sur lequel cette suite est definie, une deuxieme suite de variables aleatoires i. I. D. Telle qu'a partir d'un certain rang aleatoire n#0, les maxima des deux suites coincident. Nous estimons la variable aleatoire n#0 en demontrant qu'il existe > 0 telle que p(n#0 > s) = o((log s)#-##/#(##+#2#). Dans la troisieme partie (chapitre 3 et 4), nous considerons une suite i. I. D.

Cílem této diplomové práce jse najít nejnižší možnou tloušťku nikl-fosforového povlaku, který může být galvanicky pokoven mědí bez defektů na horčíkové slitině, nikl-fosforového nebo měděného povlaku. V teoretické části jsou shrnuty poznatky o hořčíkových slitinách a jejich korozi. Navíc se teoreticá část zaměřuje na popis procesu bezproudého niklování a elektrochemického pokovování mědí a jejich porovnání. Na konci teoretické části je shrnut současný výzkum o elektrochemickém pokovování hořčíkových slitin. V experimentální části byl popsán proces přípravy povlaků Ni-P a Cu na horčíkové slitině AZ91. Na jedné vrstvě a dvojité vrstvě Ni-P povlaku byla provedena elektrodepozice mědi. Navíc byl diskutován vliv předůpravy před samotnou elektrodepozicí mědi. Za účelem zjištění korozních vlastností vzorků byl vykonán potenciodynamický test. Následně byly připraveny metalografické výbrusy jednotlivých vzorků a pomocí světelného a rastrovacího elektronového mikroskopu byla provedena charakterizace. Na konec bylo zjištěno prvkové složení jednotlivých povlaků pomocí EDX analýzy.

xiii, 110 p. A print copy of this thesis is available through the UO Libraries. Search the library catalog for the location and call number.This dissertation investigates the interplay between, and the possible coexistence of, magnetic and superconducting order in metals. We start with studying the electromagnetic properties of s-wave superconductors near a ferromagnetic instability. By using a generalized Ginzburg-Landau theory and scaling arguments, we show that competition between magnetic order and superconducting order can change the scaling of observables. For instance, the exponent for the temperature dependence of the critical current can deviate from the Ginzburg-Landau value of 3/2. These results may be relevant to understanding the observed behavior of MgCNi 3 . We then study the nature of the superconductor-to-normal-metal transition in p-wave superconductors. Although the phase transition is continuous at a mean- field level, a more careful renormalization-group analysis in conjunction with large-n expansion techniques strongly suggest that the transition is first order. This conclusion is the same as for s-wave superconductors, where these techniques also predict a first-order transition. In p-wave superconductors, topological excitations known as skyrmions are known to exist in addition to the more common vortices. In the third part of this dissertation, we study the properties of skyrmion lattices in an external magnetic field. We propose iv experiments to distinguish vortex lattices from skyrmion lattices by means of their melting curves and their μSR signatures.

Stock prediction with artificial neural network (ANN) models has been used extensively by researchers as it provides better results than other techniques. This paper presents an ANN approach to forecast the S&P 500 stock index price. First of all, an ANN-based variable selection model is presented. This model explores the relationship between some initial input variables and the closing price of the S&P 500 stock index. Furthermore, this research investigates how the training algorithm, as well as the number of neurons in the hidden layer and the distribution of the training data, affect the accuracy of the network.

Testo completoAbstract (sommario):
La tesis se centra en los estudios de la producción inelástica de las partículas cargadas en el colisionador LHC que opera en la frontera de la energía del centro de masa de 7 TeV.
Los datos corresponden a 16 μb-1 de la primera recogida de la luminosidad integrada por el detector ATLAS, a principios de 2010.
Las secciones de la producción de las partículas cargadas fueron comparadas con la variedad de los populares modelos fenomenológicos de la QCD suave.
Los resultados reportados en la tesis constituyen una muestra de datos correspondiente a una nueva región cinemática de QCD. Por lo tanto, el leve (10-20)% desacuerdo entre los datos y las predicciones de diferentes modelos fenomenológicos no fue una sorpresa.
Los resultados reportados estuve utilizados para ajustar los modelos existentes de soft QCD para reproducir de manera adecuada la hadrónica presente en las colisiones del LHC.
El tipo de estudios presentados en la
tesis pertenece a una línea de investigación bien establecida en el ámbito de la física de alta energía (HEP), que consiste en el pleno re-descubrimiento del Modelo Estándar antes de tratar de avanzar más.
Los estudios presentados en la tesis han
conducido ya a una publicación en una revista líder de la física de altas energías, PLB (marzo 2010), y otro articulo está en preparación. Tuve un papel importante en esta primera publicación de los resultados de ATLAS.
Otro punto importante de los trabajos presentados en la tesis puede ser resumido de la siguiente manera:
1) Muy bien estructurado y buena presentación de los estudios realizados.
2) Meticuloso seguimiento de los cánones de análisis recogidos en la comunidad HEP.
3) El uso adecuado de la información más actualizada de simulaciones de soft QCD.
4) Estudios cuidadosos de los efectos de las condiciones del detector y de la eficiencia del trigger para seleccionar los resultados.
5) La evaluación cuidadosa de los errores sistemáticos.The thesis is focused on the studies of the inclusive inelastic production of the charged particles at the LHC collider that operates at the frontier center-of-mass energy of 7TeV. The analyzed data correspond to about sixteen inverse micro-barn of the very first integrated luminosity collected by the ATLAS detector by the beginning of 2010. Having fully taken advantage of above factors, scrupulous studies performed in the thesis resulted in the measurements of the charged particles inclusive production cross-sections that were compared to the variety of popular phenomenological models of the soft QCD. The results reported in the thesis constitute a novel data sample corresponding to a new kinematic QCD region. Thus, the mild (10-20)% disagreement between the data and the predictions of different phenomenological models came as no surprise. The reported results were used to adjust existing soft QCD models to adequately reproduce the busy hadronic environment present in the LHC collisions, thus reinforcing current theoretical framework. The type of the studies presented in the thesis belongs to a well established research line in the field of high energy physic (HEP) that consists of full re-discovery of the Standard Model in the environment of new collider experiment before attempting to move further. Studies presented in the thesis have already led to one publication in the leading high energy physics journal, PLB (March 2010), and another paper is in preparation. I took an important role in this, very first publication of the ATLAS results, often considered as an informal criteria for the PhD thesis merits inside of the HEP community. Additional strong points of the work presented in the thesis may be summarized as following: 1) Very well structured and focused presentation of the studies performed. 2) Meticulous following of the analysis canons adopted in the HEP community. 3) Appropriate usage of the most up-to-date soft QCD simulations. 4) Careful studies of the impact of the detector conditions and trigger selection efficiency on the results. 5) Careful evaluation of the systematic errors on the reported cross-sections and distributions.

Previous issue date: 2003-12-02The research investigates the acting and the importance for the users of the public squares located predominantly in residential areas. It presents the results of the posoccupation evaluations accomplished in three squares, whose physical, environmental characteristics, equipments and fumitures are different in its qualities and amounts, taking in consideration aspects related to the users' physical and psychological comfort and of the inhabitants of the I spill. The collection of data involved physical risings and of files, observations behavious, application of questionnaires and interviews, analyzed qualitative as quantitatively so much for a larger precision and validity of the investigation. The results were obtained through the relationship among the users' perception the environmental attributes and the different levels of apropriation/use of the studied places. They indicate that the aspects composicionais of physical order of the space affects the type and the intensity of use of the squares intimately, contributing positive or negatively for its valor. It is evidenced like this, that the low freq?entation of the public squares of Natal, is due mainly to referring aspects to the physical quality and the amount of the fumitures and urban equipments. It is ended that the investments and the physical planning of these public spaces should be based in the real knowledge of the aspirations of the population objective, in way to allow its largest use and valor

Lam, Kar-Hei. "Essays on the modelling of S&P 500 volatility". Thesis, City University London, 2004. http://openaccess.city.ac.uk/8406/.
Testo completoAbstract (sommario):
This dissertation studies the patterns of term-structure of implied volatility and examines the performance of different specifications of time-series and options-based volatility forecasting models under the influence of the observed market biases. Our research is based primarily upon the use of S&P 500 data for the period 1982-2002. There are three self-contained but seemingly related projects in this dissertation. The objectives of this research are: 1) to characterise the term-structure of implied volatility; 2) to compare the performance of asymmetric power ARCH and EGARCH models; 3) to evaluate the forecasting performance of time-series and options-based variance swap valuation models. The observed market anomalies in the term-structure of implied volatility of S&P 500 futures options are investigated between 1983 and 1998. Term-structure evidence indicates that short-term options are most severely mispriced by the Black-Scholes formula. We find evidence that option prices are not consistent with the rational expectations under a mean-reverting volatility process. In addition, skewness premiums results show that the degrees of anomalies in the S&P 500 options market have been gradually worsening since around 1987. As correlation may be responsible for skewness, our diagnostics suggest that leverage and jump-diffusion models are more appropriate for capturing the observed biases in the S&P 500 futures options market. Sixteen years of daily S&P 500 futures series are employed to examine the performance of the APARCH models that use asymmetric parameterisation and power transformation on conditional volatility and its absolute residual to account for the slow decay in returns autocorrelations. No evidence can be found supporting the relatively complex APARCH models. Log-likelihood ratio tests confirm that power transformation and asymmetric parameterisation are not effective in characterising the returns dynamics within the context of APARCH specifications. Furthermore, results of a 3-state regime-switching model support the notion that the performance of conditional volatility models is prone to the state of volatility of the returns series. In addition, AIC statistics stipulate that EGARCH is best in "noisy" periods whilst GARCH is the top performer in "quiet" periods. Overall, aggregated rankings for the AIC metric show that the EGARCH model is best. Options-based volatility trading exercises also reveal that EGARCH and GARCH can generate statistically significant ex-ante profit in one out of four sample periods after transactions costs. When considering a stochastic volatility model, there seems to be little incentive to look beyond a simple model which allows for volatility clustering and a leverage effect. The volatility forecasting performance of different specifications of time-series and options-based variance swap valuation models on the S&P 500 index is evaluated from three months before to after the 9/11 attacks. By far, the option-basedD emeterfi et al. (1999) variances wap valuation framework is the most popular tool to price variance swaps. This framework stipulates that pricing a variance swap can be viewed as an exercise in computing the weighted average of the implied volatility of the options required even under the influence of volatility skew. Our research design offers a comprehensive empirical study of the relative merits of competing option pricing models. Based on results from six carefully chosen contract days, we illustrate that implied models may overpredict future variance and underperform time-series models. The reasons could be: 1) the implied strategy was originally developed for hedging; 2) implied volatility is predominantly a monotonically decreasing function of maturity and therefore options-based strategy cannot produce enough variance term-structure patterns; 3) distributional dynamics implied by option parameters is not consistent with its time-series data as stipulated by the maximum likelihood estimation of the square-root process. Future research needs to use a larger sample set in order to establish a more statistically significant result to justify our findings. Until then we have a strong reservation about the use of Demeterfi et al. methodology for variance forecasting.

Previous issue date: 2008-03-25A drenagem venosa sist?mica do enxerto pancre?tico tem sido associada ? hiperinsulinemia, que, por sua vez, pode estar relacionada ? dislipidemia, resist?ncia insul?nica (RI) e s?ndrome metab?lica. ? poss?vel que a RI seja respons?vel, pelo menos em parte, pela hiperinsulinemia descrita em transplantados de p?ncreas, atribu?da ? drenagem venosa sist?mica. Entretanto a preval?ncia de resist?ncia ? insulina associada a este procedimento bem como a capacidade da c?lula beta do enxerto em sobrepor-se a este efeito n?o s?o bem conhecidas. O objetivo desse estudo foi avaliar o metabolismo glic?dico em transplantados de p?ncreas com drenagem venosa sist?mica, atrav?s de insulinemia, glicemia e pept?deo C de jejum, hemoglobina glicosilada, HOMA e curvas de glicose e insulina s?ricas ap?s sobrecarga de glicose. Foram analisados 30 transplantados de p?ncreas insulino-independentes, 23 SPK, 2 PAK e 5 PTA. A glicemia, insulinemia e pept?deo C basais foram respectivamente: 85,7+-14,2 mg/dl, 17,8+-8,6 mU/ml, 3,4+-1,7 ng/ml. A hemoglobina glicosilada m?dia foi de 6,0(+-0,7)%. Atrav?s do HOMA, identificou-se dois grupos de pacientes, insulino-resistentes (n=20) e insulino-sens?veis (n=10). Ambos apresentaram controle glic?mico adequado e semelhante, entretanto, apenas o grupo resistente apresentou hiperinsulinemia basal, al?m de resposta insul?nica exacerbada ? sobrecarga de glicose oral. Conclui-se que hiperinsulinemia n?o ? achado universal em transplantados de p?ncreas com drenagem venosa sist?mica. Tal achado parece estar relacionado com resist?ncia ? insulina, presente em grande parte desta popula??o. Ainda, o controle glic?mico ? adequado, evidenciando a capacidade da c?lula beta pancre?tica a sobrepor-se ao aumento da RI.

Testo completoAbstract (sommario):
Cette étude porte sur quatre départements (Gard, Morbihan, Nord, Val-de-Marne), qui présentent des caractéristiques différentes sur les plans géographique, démographique, économique ou culturel, et vise à cerner l'identité professionnelle des enseignants de S. E. G. P. A. . En effet, ce statut très particulier pourrait déjà les différencier de leurs collègues du primaire, mais aussi de ceux du collège. Le statut de ces enseignants apparaît paradoxal, car d'une part ils dépendent du 1 degré tout en exerçant dans le second degré; d'autre part s'ils exercent en collège, les structures spécialisées dans lesquelles ils enseignent sont à la marge des collèges, et ce malgré les intentions affichées par la loi d'orientation de 1989 ou les circulaires de 1996 et 1998, qui définissent l'intégration des S. E. G. P. A. . Nous avons étudié les motivations qui ont poussé ces enseignants à travailler dans l'éducation spécialisée en collège plutôt qu'en primaire. Nous avons mis en évidence que si les situations sont différentes dans ces quatre départements, l'idée d'une identité commune l'emporte néanmoins. Notre recherche s'appuie sur des données historiques relatives aux origines de l'enseignement spécialisé, sur des données statistiques concernant l'enseignement spécialisé ou non, sur des données sociologiques étudiant le statut des enseignants du premier et du second degré, sans pour autant négliger les textes qui régissent les SEGPA, qu'ils soient anciens (1967) ou plus récents (loi d'orientation de 1989 ou circulaire de 1996 et 1998 sur la rénovation des collèges). L'enquête par questionnaires, complétée par des entretiens individuels, nous a permis d'appréhender plus finement l'identité professionnelle de ces enseignants, et de mettre à jour une identité propreThis study focusses on four French departments (the Gard, the Morbihan, the Nord and the Val-de-Marne) which present different geographic, demographic, economic or cultural characteristics, and aims at defining the professional identity of SEGPA teachers. In fact, their special status does already tend to set them apart from their colleagues both in primary and secondary schools. The status of these teachers seems paradoxical because, on the one hand, they come under the control of Primary Education sector while teaching in the Secondary Education system; and on the other hand, although they work in middle schools, the special units in which they teach are not fully integrated into the Secondary system, in spite of the measures put forward by the 1989 "Loi d'Orientation" (Framework Law) or the circulars of both 1996 and 1998 which define the integration of SEGPAs. We have made a study of the motives which have prompted these teachers to work in special education in a middle school rather than in primary education. We have highlighted the fact that though the situations are different in the four departments, the idea of a common identity nevertheless prevails. Our research draw on historical data relating to the origins of special education, on statistical data regarding education, special or not, on sociological data studying the status of both primary and secondary education teachers, without overlooking the laws that rule SEGPAs, whether (1967) or more recent (1989 Loi d'Orientation or 1996 and 1998 circulars on the renovation of middle schools). The survey questionnaires, followed up by individual interviews, have given us a clearer understanding of the professional identity of SEGPA teachers and revealed the specificity of their role

Testo completoAbstract (sommario):
L'objectif premier de cette thèse a été la recherche d'un nouvel outil de synthèse pouvant jouer le rôle d'équivalents synthétiques de Carbone Atomique Asymétrique et pouvant être facilement utilisé dans des contions classiques de laboratoire. Pour cela nous avons synthétisé le premier Phosphonio-Sulfonio-Bis-Ylure dissymétrique, comportant deux fonctions ylures différentes cumulées sur un carbone central. Le travail exposé dans ce mémoire aborde trois différentes problématiques : Le premier chapitre de ma thèse sera dédié à un état de l'art des molécules pouvant être sources de carbone atomique. Le second chapitre sera consacré à l'étude d'une voie de synthèse simple et adaptable de Phosphonio-Sulfonio-Bis-Ylures stables et isolables. Nous présenterons également dans celui-ci une étude de leurs structures cristallographiques et électroniques originales. Dans le troisième chapitre, nous nous attacherons à démontrer le fort potentiel des Bis-Ylures-P,S en tant qu'équivalent synthétique de carbone atomique asymétrique. Nous montrerons également le développement d'une nouvelle méthodologie permettant de réaliser les réactions de Wittig des bis-ylures à température ambiante. Enfin, dans le quatrième chapitre, nous présenterons l'utilisation des bis-ylures-P,S comme précurseurs de carbènes. Nous avons pour cela exploité le caractère de bon nucléofuge du fragment sulfonium pour le substituer par un fragment phosphéniumThe prime objective of this PhD was the research of a new synthetic tool able to react as a synthetic equivalent of asymmetric atomic carbon and usable in classic laboratory conditions. For this, we have synthesized the first dissymmetric Phosphonio-Sulfonio-Bis-Ylide, including two different ylide functions cumulated on a central carbon. The research work presented in this memoir got onto three different problematics : The first chapter presents a state of the art of the molecules usable as a source of atomic carbon. In the second chapter, we present a study of a straightforward and adaptable synthetic way to a stable and isolable Phosphonio-Sulfonio-Bis-Ylide. In this part, is also completely detailed their original crystallographic and electronic structures. In the third chapter, we demonstrate the high potential as a synthetic equivalent of asymmetric atomic carbon of the P,S-Bis-Ylides. We show also the development of a new methodology allowing the realization the Wittig reactions at room temperature. Finally, the fourth chapter presents the use of P,S-Bis-Ylides as precursors of carbenes. To realize it, we have exploited the good leaving group nature of the sulfonium fragment to substitute it by a phosphenium fragment
