Nef, Annliese. "L'élément islamique dans la Sicile normande : identités culturelles et construction d'une nouvelle royauté (XIe - XIIe siècles)." Paris 10, 2001. http://books.openedition.org/efr/5336.
Full textAbstract:
En 1061, lorsque les Normands entreprennent la conquête de la Sicile, la population insulaire est majoritairement arabo-musulmane, même si la partie orientale demeure profondément hellénisée. Malgré ces difficultés, l'île s'offre comme un terrain de choix pour l'affirmation de la dynastie des Hauteville et la construction d'un pouvoir sans partage. Minoritaires tant d'un point de vue démographique que culturel, ces hommes du nord ont à faire face à un véritable défi. En quelques générations, le comte Roger et ses descendants réussissent à instaurer une royauté qui, pour durer, doit faire l'objet d'un consensus en Sicile même et jouir d'une reconnaissance à l'extérieur. Cette quête de légitimité, qui passe par la mobilisation des héritages latin, islamique et grec (byzantin) qui sont aussi bien ceux des conquérants que des conquis, fait de la Sicile un véritable laboratoire où sont mises à l'épreuve de nouvelles conceptions liées à la royauté. Ce problème politique se pose essentiellement en termes culturels. Comment dire, par exemple, le pouvoir politique dans un contexte trilingue ? Les Normands adoptent ici une position paradoxale. Utilisant le grec, le latin et l'arabe dans l'administration, ils se servent de ces idiomes autant pour reprendre à leur compte les deux traditions insulaires que pour tenir à distance leurs sujets. La référence religieuse n'est pas moins délicate à manier à une époque où la dimension religieuse est étroitement liée à la légitimation du pouvoir royal à Byzance, en Occident et dans les pays islamiques. De la fondation d'évêchés latins à la fin du XIe siècle, on passe à la promotion d'un milieu melkite (chrétien hellénophone et arabophone de Syrie) et mozarabe, puis à l'exaltation d'un monothéisme souple. L'échec de cette tentative unique qui associe trois traditions culturelles découle de l'écart qui se crée peu à peu entre des souverains dont l'identité culturelle mêle des éléments de plus en plus divers et des groupes culturels qui, entre effacement et résistance, ne se retrouvent guère dans cette convergence partielle et limitée au milieu de courIn 1061, when the Normans begin their conquest of Sicily, the insular population is for the main part of Islamic culture, even if the Oriental regions remain hellenized in depth. In spite of these difficulties, the island offers a perfect ground for the affirmation of the Hautevilles' dynasty and for the construction of an unshared power. Nonetheless, a representing a cultural minority Sicily, these men from the North face a real challenge. Within a few generations, Count Roger and his descent will set up a kingship which, in order to last, must be supported by a consensus in the island and be acknowledged legitimacy outside of it. Such a quest for legitimacy requires the mobilization of Latin, Islamic and Greek (Byzantine) legacies which belong to the conquerors and to the insular population. It transforms Sicily in a true laboratory where new conceptions linked to Kingship are tested. This political problem presents itself essentially in cultural terms. How can, for example, political power be expressed in a trilingual context ? The Norman adopt on this issue a paradoxical position. They use Greek, Latin and Arabic in their administration as much in order to resume with the insular traditions as in order to put distance between themselves and their subjects. Handling the religious reference is no less difficult at a time when the religious dimension is linked straightly to the legitimation of royal power, at Constantinople, as well as in Occident and in the Islamic countries. From the foundation of Latin bishoprics, they go on with the promotion of a Melkite (Christian Hellenophone and Arabophone from Syria) and Mozarabic milieu, ending up with the exaltation of a flexible monotheism. The failure of this unique attempt which associates three cultural traditions is due to the gap that appears little by little between kings whose cultural identity put together more and more diverse elements and cultural groups which, oscillating between disappearance and resistance, do not perceive much of themselves in this partial convergence, limited to the royal Court

Full textAbstract:
L'approche religieuse de la mer par les grecs est communément assimilée aux seules figures de Poséidon et des divinités dites + marines, telles les néréides, ino ou les Dioscures. Or, dans la pratique, il s'avère que la majorité des cultes réalisés dans un contexte maritime ou lors d'un voyage en mer s'adressent aux divinités olympiennes ou douze dieux. L'ensemble du travail tend à définir les pratiques religieuses des marins grecs et à considérer la place primordiale qu'y occupent les dieux olympiens. Dans une premiere partie, sont ainsi passées en revue les relations de chacun de ces dieux avec la mer : à travers les récits mythologiques et épiques, puis géographiquement à travers tout le monde grec, région par région, sanctuaire par sanctuaire. Dans une seconde partie, sont décrites les pratiques religieuses spécifiques au monde maritime. En mer, la présence des dieux se manifeste à bord du bateau de differentes manières : par l'ornementation navale, par les noms théophores du navire, par les ancres portant inscriptions ou décors. A terre, en relation avec un voyage maritime, sont consacrés dans des sanctuaires des bateaux sous differentes formes, ainsi que des ancres et des ex-voto de pêche. L'étendue de la période étudiée permet de discerner des évolutions dans les caractères prêtés aux dieux et dans les cultes maritimes, et l'importance de ceux-ci à l'époque archaïque. Leur répartition et la topographie des sanctuaires présentent des cohérences liées aux méthodes et conditions de navigation antique. Le culte marin des divinités olympiennes manifeste de la grande souplesse de la religion grecque - adaptation de personnalités divines a un contexte géographique ou social - tout en formant un ensemble ordonneThe religious approach of the sea by Greeks is commonly classed as the figure of Poseidon and deities so said + marine; like nereids, ino or Dioscuri. But, in the reality it turns out that the majority of worships make in maritime context or in travel by sea address to the Olympian deities or twelve gods. All this study aims to define the religious practices of Greek sailors and to consider the primordial place of the Olympian deities. In the first part, are reviewed relationships of all these gods with the sea : by the mythological and epic words, then geographically through all Greek world, region by region, sanctuary by sanctuary. In the second part, are described the religious practices specific to maritime world. By sea, the presence of gods emerge aboard ships by different ways : by nautical ornamentation, by theophoric names, by anchors with inscriptions or decorations by land, in connection with nautical travel, are dedicated in sanctuaries boats in different forms, anchors and fishing gifts. The duration of period examined permit to discern evolutions in the features of gods and in the maritime worships, and importance of these in the archaic time. There repartition and the topography of sanctuaries present coherences connected to methods and conditions of ancient seamanship. The worship of Olympian deities demonstrate a large adaptability of Greek religion - adaptation of sacred personalities in a geographical or social context - making an arranged whole

Full textAbstract:
This project is intended to take the film To Live, directed by Zhang Yimou, and apply the Electronic Film Review (EFR) approach to it in a Chinese as a Foreign Language (CFL) setting. The Electronic Film Review project, developed by Alan K. Melby, is aimed at providing a superior language learning experience for Americans learning Chinese. Using feature films as a teaching tool has been found to stimulate and motivate students to achieve higher language levels, but in order for optimal learning to occur the material must be challenging yet accessible to the student. Most feature films, by themselves, are too advanced for the average language learner. The EFR approach provides annotations designed specifically for the feature film with the language learner in mind. These annotations can include access to vocabulary helps, grammar and cultural notes in order to bridge the gap between the learner and the film. It does not alter the film itself. This approach has been used with ESL students (English annotations), French language learners, and with Korean ESL learners (Korean annotations), but has not been developed for students learning Chinese. The purpose of this project is not only to apply the technology of the Electronic Film Review program to a Chinese film for the purpose of aiding Chinese language learners, but also to critique whether or not the tool is effective in helping students to gain better listening comprehensions skills and therefore ultimately better language skills. Previous studies have not shown clear results on this issue. This thesis will briefly review what the EFR project is and how it has been used with other films and languages as well as the findings up to this point. Then it will look at the effects of annotations on several aspects of listening comprehension as well as student preferences and reactions. It will then evaluate the results collectively to determine whether students watching the film without the help of EFR annotations show differing levels of listening comprehension achievement when compared with those using the EFR tools. Suggestions will be made for further improvements.

Chmayssani, Toufic. "Modulation sur les canaux vocodés." Phd thesis, Université Paris-Est, 2010. http://tel.archives-ouvertes.fr/tel-00587629.
Full textAbstract:
Les canaux vocodés sont les canaux de communications dédiés à la voix et dans lesquels le signal traverse divers équipements destinés au transport de la voix tels que des codeurs de parole, des détecteurs d'activité vocale (VAD), des systèmes de transmission discontinue (DTX). Il peut s'agir de systèmes de communications téléphoniques filaires ou mobiles (réseaux cellulaires 2G/3G, satellites INMARSAT...) ou de voix sur IP. Les codeurs de parole dans les normes récentes pour les réseaux de téléphonie mobiles ou de voix sur IP font appel à des algorithmes de compression dérivés de la technique CELP (Code Excited Linear Prediction) qui permettent d'atteindre des débits de l'ordre de la dizaine de Kb/s bien inférieurs aux codeurs des réseaux téléphoniques filaires (typiquement 64 ou 32 Kb/s). Ces codeurs tirent leur efficacité de l'utilisation de caractéristiques spécifiques aux signaux de parole et à l'audition humaine. Aussi les signaux autres que la parole sont-ils généralement fortement distordus par ces codeurs. La transmission de données sur les canaux vocodés peut être intéressante pour des raisons liées à la grande disponibilité des canaux dédiés à la voix et pour des raisons de discrétion de la communication (sécurité). Mais le signal modulé transmis sur ces canaux vocodés est soumis aux dégradations causées par les codeurs de parole, ce qui impose des contraintes sur le type de modulation utilisé. Cette thèse a porté sur la conception et l'évaluation de modulations permettant la transmission de données sur les canaux vocodés. Deux approches de modulations ont été proposées pour des applications correspondant à des débits de transmission possibles assez différents. La principale application visée par la thèse concerne la transmission de parole chiffrée, transmission pour laquelle le signal de parole est numérisé, comprimé à bas débit par un codeur de parole puis sécurisé par un algorithme de cryptage. Pour cette application, nous nous sommes focalisés sur les réseaux de communications utilisant des codeurs CELP de débits supérieurs à la dizaine de Kb/s typiquement les canaux de communication mobiles de deuxième ou troisième génération. La première approche de modulation proposée concerne cette application. Elle consiste à utiliser des modulations numériques après optimisation de leurs paramètres de façon à prendre en compte les contraintes imposées par le canal et à permettre des débits et des performances en probabilité d'erreur compatibles avec la transmission de parole chiffrée (typiquement un débit supérieur à 1200 b/s avec un BER de l'ordre de 10-3). Nous avons montré que la modulation QPSK optimisée permet d'atteindre ces performances. Un système de synchronisation est aussi étudié et adapté aux besoins et aux contraintes du canal vocodé. Les performances atteintes par la modulation QPSK avec le système de synchronisation proposé, ainsi que la qualité de la parole sécurisée transmise ont été évalués par simulation et validés expérimentalement sur un canal GSM réel grâce à un banc de test développé dans la thèse.La deuxième approche de modulation a privilégié la robustesse du signal modulé lors de la transmission à travers un codeur de parole quelconque, même un codeur à bas débit tels que les codeurs MELP à 2400 ou 1200 b/s. Dans ce but, nous avons proposé une modulation effectuée par concaténation de segments de parole naturelle associée à une technique de démodulation qui segmente le signal reçu et identifie les segments de parole par programmation dynamique avec taux de reconnaissance élevé. Cette modulation a été évaluée par simulation sur différents codeurs de parole. Elle a aussi été testée sur des canaux GSM réels. Les résultats obtenus montrent une probabilité d'erreur très faible quelque soit le canal vocodé et le débit des codeurs de parole utilisés mais pour des débits possibles relativement faibles. Les applications envisageables sont restreintes à des débits typiquement inférieurs à 200 b/s.Enfin nous nous sommes intéressés aux détecteurs d'activité vocale dont l'effet peut-être très dommageable pour les signaux de données. Nous avons proposé une méthode permettant de contrer les VAD utilisés dans les réseaux GSM. Son principe consiste à rompre la stationnarité du spectre du signal modulé, stationnarité sur laquelle s'appuie le VAD pour décider que le signal n'est pas de la parole

Full textAbstract:
Dans les communications radio-mobiles, la qualité de la parole est fortement impactée par les erreurs résiduelles en sortie du décodeur canal. Celles-ci résultent des paquets d'erreurs introduits par le canal radio alors que les contraintes de complexité limitent les performances du codage canal. Parallèlement, ces mêmes contraintes font qu'il subsiste une redondance résiduelle en sortie du codeur de parole. Cette redondance résiduelle fournit une information a priori qui peut être exploitée au niveau du décodeur de parole pour minimiser l'erreur d'estimation des paramètres transmis, ou au niveau du décodeur canal pour minimiser le taux d'erreurs résiduelles. Nous étudions chacune de ces approches ainsi que leur combinaison dans le cas du GSM EFR. Au niveau du décodeur parole, nous modélisons la redondance résiduelle des paramètres du codeur à l'aide de mélanges de gaussiennes ce qui permet de réduire la complexité de l'estimation par rapport aux méthodes existantes et délivre une information plus riche sur la redondance résiduelle. Au décodeur canal, nous améliorons la prise en compte de la redondance résiduelle entre les bits d'une même trame par une technique de prédiction le long des chemins du treillis. Ces approches sont évaluées sur des simulations de transmission par l'algorithme PESQ de mesure objective de la qualité vocale. Le décodeur de parole exploitant la redondance résiduelle apparaît supérieur au décodeur classique du GSM EFR avec masquage d'erreur. En revanche, les performances du décodeur canal exploitant la redondance résiduelle sont sensibles à la correspondance choisie ente les éléments du dictionnaire de quantification et leur étiquetage binaireIn digital mobile radio systems, the speech quality can be severly degraded if the channel decoder produces residual bit errors due to heavy burst errors on the radio path. On the other hand, in most speech coding schemes some residual redundancy remains because of complexity and delay limitations. A solution for improving the speech quality consists in using a priori information based on source residual redundancy at the receiver side. In one approach, a priori information is used at the source decoder to perform optimal estimation of transmitted codec parameters. In another approach, a priori information is used at the channel decoder in oder to minimize the residual bit errors rate. We study both approaches and apply them to the GSM EFR. At the speech decoder level, we model the residual redundancy of speech codec parameters by using Gaussian mixtures. This model reduces the complexity when compared to state-of-art methods and provides a better representation of residual redundancy. At the channel decoder level, we introduce an efficient method to exploit intra-frame bit redundancy during the channel decoding process. In this method, the value of the bit being decoded is predicted from the bits already decoded along the treillis path. These methods are evaluated on simulations of radio transmission by an objective measure of speech quality. In all cases, the performance of the speech decoder using our residual redundancy model turns out to be better than the GSM EFR decoder with standard error concealment procedure. The performance of the channel decoder using residual redundancy is strongly dependent of the index assignment used by the quantifier

Full textAbstract:
Mobile telephony technology like GSM made portable telephony a possibility. The arising and development of the Internet made a revolutionary change to communication and interchange of information. Bluetooth wireless technology revolutionizes personal connectivity by providing freedom from wired connections. Combining these technologies together brings the concept of Mobile@Home of Ericsson.
Mobile@Home is a fixed-mobile convergence concept using the fixed network to carry present and future mobile services (e.g. voice, video, mail and Internet access) all the way to the home or office. By combining the high bandwidth of the fixed access network with the wireless technology of Bluetooth, Mobile@Home makes it possible to deliver high bandwidth to the mobile phone. Mobile@Home requires a Bluetooth enabled mobile phone and a Bluetooth enabled HBS (Home Base Station), placed at the home or office. By means of fast IP access (ADSL, cable modem etc.) the HBS connects into the standard mobile core network through a HBSC (Home Base Station Controller).
The purpose of this thesis is the generation of simulated traffic between the HBS and HBSC and to analyze its behavior. This primary involves generation of signaling through an internal protocol, provided by Ericsson, for management and call control, and generation of GSM EFR (Enhanced Full Rate) voice streams over the RTP (Real Time Protocol) protocol. The simulation will consist of both the HBS and MS (Mobile Station). A set of HBS: s with attached MS will call one another through the HBSC. In this assignment only the GSM signaling will be considered because of time and scope limitations. The goal is to validate the RTP traffic generated towards the HBSC. Parameters like packet loss, packet delay and erroneous packets will be analyzed.

Internet som är något som de flesta använder sig av, blir allt mer populärt att kombinera internetanvändning när det gäller att betala räkningar. Elektronisk faktura är ett sätt att presentera faktura elektroniskt. Syftet med detta projekt har varit att skapa en fuskbank som kan interagera med e-fakturaflöden och motsvara en certifierad teknisk distributör samt presentatörsbank. Fuskbanken tar emot filer av filformatet EFB som bland annat innehåller betalrader med tillhörande länkar till fakturaspecifikation. EFB-filen innehåller information som visas i en internetbank för en privatpersons e-faktura. Fuskbanken ska kunna skapa två filer av filformatet EFBR och EFA. EFBR är en återredovisningsfil för EFB, och EFA används till avanmälning av e-faktura. Fuskbankens uppgift är att parsa en EFB-fil för att sedan sätta in den i en databas. Därefter ska en parsad fil visas i ett webbgränssnitt. Utifrån ett webbgränssnitt ska det vara möjligt att skapa EFBR- och EFA-filer. Vid skapandet av fuskbanken användes Java 6 som programmeringsspråk och en applikationsserver vid namn JBoss application server 7. MySQL användes för databas och för webbgränssnitt användes Primefaces. Resultatet är en fuskbank som kan interagera med e-fakturaflöden och visa var i en parsad EFB-fil ett formatfel uppstod. Av de mätningar som gjorts framkommer det att tiden det tar att parsa en EFB-fil är skäligt. Fuskbanken kommer endast användas i testmiljö varför den information som sätts in i en databas reflekterar inte riktiga efakturakunders fakturor.

Full textAbstract:
Sectra Communications AB has developed a terminal for encrypted communication called the Tiger platform. During voice communication delays have sometimes been experienced resulting in conversational complications.
A solution to this problem, as was proposed by Sectra, would be to introduce voice activity detection, which means a separation of speech parts and non-speech parts of the input signal, to the Tiger platform. By only transferring the speech parts to the receiver, the bandwidth needed should be dramatically decreased. A lower bandwidth needed implies that the delays slowly should disappear. The problem is then to come up with a method that manages to distinguish the speech parts from the input signal. Fortunately a lot of theory on the subject has been done and numerous voice activity methods exist today.
In this thesis the theory of voice activity detection has been studied. A review of voice activity detectors that exist on the market today followed by an evaluation of some of these was performed in order to select a suitable candidate for the Tiger platform. This evaluation would later become the foundation for the selection of a voice activity detector for implementation.
Finally, the implementation of the chosen voice activity detector, including a comfort noise generator, was done on the platform. This implementation was based on the special requirements of the platform. Tests of the implementation in office environments show that possible delays are steadily being reduced during periods of speech inactivity, while the active speech quality is preserved.

Full textAbstract:
Nous avons étudié le peuplement des états discrets par réactions de stripping d'un nucléon sur une cible de ²⁰⁸Pb, induites par le faisceau de 480 MeV de ¹ ² C fourni par le laboratoire national GANIL à Caen. Nous avons mesuré les spectres en énergie des éjectiles avec une résolution en énergie de 200 keV de largeur à mi-hauteur à l'aide du spectromètre magnétique à perte d'énergie SPEG. Nous avons analysé les niveaux discrets, présents jusqu'à 6 MeV d'énergie d'excitation et de larges structures présentes à 9-10 MeV. La comparaison avec des résultats obtenus avec un faisceau de 160 à 793 MeV où 1e nucléon transféré se trouve dans une configuration initiale différente que dans le cas du ¹ ² C, a montré que le peuplement des états discrets aux énergies incidentes de quelques dizaines de MeV par nucléon est gouverné par deux règles de sélection : 1) Les niveaux les plus peuplés correspondent à des états de grand moment angulaire car les moments angulaires pour les ondes rasantes d'entrée et de sortie diffèrent de plusieurs unités. 2) Les niveaux les plus peuplés correspondent aux transitions qui se font sans retournement du spin : le nucléon transféré tourne dans le même sens autour des cœurs des noyaux avant et après le transfert. Ce comportement est opposé à ce qui se passe à basse énergie. Ces règles sont bien comprises dans le cadre du modèle semi-classique de D. M. Brink (1972) et implicitement contenues dans les calculs suivant l'approximation de Born en ondes distordues en portée finie (EFR-DWBA). L'analyse EFR-DWBA reproduit très bien les sections efficaces différentielles aussi bien en forme qu'en valeur absolue pour le système ¹ ² C + ²⁰⁸Pb à 480 MeV. Cela nous a permis d'extraire les facteurs spectroscopiques qui sont en bon accord avec ceux qui sont connus théoriquement ou extraits expérimentalement à plus basse énergie ou encore avec des projectiles plus légers. Nous avons étudié en détail l'influence des différents paramètres qui rentrent dans le calcul des sections efficaces. Les noyaux éjectiles ayant un spin, nous avons aussi fait des calculs en introduisant un terme de spin-orbite dans le potentiel optique de la voie de sortie. Nous avons de plus observé les composants de la fragmentation d'états de particule indépendante de haut spin à haute énergie d'excitation qui sont favorisés par les deux règles de sélection. Les facteurs spectroscopiques correspondants sont en accord avec des expériences de stripping d'un nucléonWe have studied at the GANIL facility (Caen) the one-nucleon stripping reactions (¹ ² C,¹ ¹ C) and (¹ ² C,¹ ¹ B) on a ²⁰⁸Pb target at an incident energy of 480MeV. We have analysed the energy spectra up to 15 MeV excitation energy. The energy resolution obtained with the energy loss magnetic spectrometer SPEG was 200 keV FWHM. The comparison with similar reactions induced by 160 on ²⁰⁸Pb at 793 MeV gives experimental evidence of the population of the excited discrete levels in terms of two selection rules : 1) High spin states are selected ; 2) the most populated states correspond to no spin-flip transitions. These rules are well understood in the semi-classical model of D. M. Brink, and are contained in the Exact Finite Range-Distorted Wave Born Approximation (EFR-DWBA) formalism. The angular distributions of the observed states were measured between 2° and 9° in the laboratory system. The EFR-DWBA calculations reproduce fairly well their shape, allowing us to extract spectroscopic factors in agreement with those previously known. EFR-DWBA calculations for ¹ ² C induced reactions reproduce also the absolute values of the cross sections for all the analysed states, while for the reaction induced by l6O the theory overestimates the experimental values by a factor of five to ten. A detailed study of the influence of the various parameters was carried out: the optical model parameters extracted from elastic scattering, which was also measured, and the form factor parameters, which were taken from previous studies at lower incident energy for the same system. The EFR-DWBA absolute cross sections are found to be very sensitive to the optical potential reduced radius, which, on the other hand, doesn't affect much the shape of the transfer reaction angular distributions. Moreover, between 4 and 10 MeV excitation energy, broad peaks and large structures have been observed, which are attributed to the excitation of high spin states which are fragmented into many components. We have looked at the effect of a spin-orbit term in heavy ion reactions at high energy. Polarization measurements are necessary to determine without ambiguities if this term does or does not play an important role, as we might expect from the fact that the angular momenta involved in the reactions investigated here are very large

Full textAbstract:
Background: Glioblastoma is the most common and aggressive type of glioma and associated with poor prognosis. Apart from ionizing radiation and some rare genetic disorders, few aetiological factors have been identified for primary brain tumours. Inverse associations to asthma and low IgG levels for varicella zoster virus have in previous studies indicated that the immune system may play a role in glioma development. Little is known about prognostic factors in glioma. Previous studies have shown an association between age, Karnofsky performance status, O6-methylguanine-DNA methyltransferase (MGMT) hypermethylation, and prognosis. Polymorphisms in different low penetrance genes have in some studies been associated with glioma prognosis. Material and methods: In paper I, we analysed IgG levels for four different viruses, Epstein-Barr virus (EBV), cytomegalovirus (CMV), varicella zoster virus (VZV) and adenovirus (Ad), in prediagnostic blood samples from 197 cases with glioma and 394 controls collected from three large cohorts: the Northern Sweden Health and Disease Study; the Malmö Diet and Cancer Study; and the Diet, Cancer and Health cohort from Copenhagen. ELISA was used to measure IgG levels and for EBV response to both the nuclear antigen (EBNA1) and the viral capsid antigen (VCA) was measured, for VCA using immunoflourescence. IgG levels were divided into quartiles and binary logistic regression was used to compare the quartiles in cases and controls. All odds ratios were adjusted for age, sex, and cohort. In paper II-IV, we studied 176 glioblastoma cases from Sweden and Denmark. We collected treatment and follow-up data on the cases. We genotyped 30 tagging SNPs in EGF, 89 in EGFR, 27 in VEGFR2, and 17 in VEGF. We also studied 1458 SNPs in 136 DNA repair genes. Hazard ratios were calculated using Cox regression; the major allele was set as categorical variable and all HR were adjusted for age, sex, country, and treatment. For the DNA repair gene results, we adjusted the p-values for multiple testing. Significant findings were confirmed in separate datasets. Results and Discussion: We found a trend towards higher IgG VZV levels in controls compared to glioma cases, especially when restricting the analyses to only include glioma cases with at least 2 years between blood sample and diagnosis. This finding might indicate that there is an aetiological and not a disease-related association. This confirms previous findings and support that a strong immune system can detect and inhibit growth of small cancer clusters. In EGF, we found seven SNPs in one haplotype block that were significantly associated with glioblastoma survival. Four of the SNPs were available for confirmation; however, none reached statistical significance. One explanation could be age differences in the different cohorts. In EGFR, four SNPs associated with survival were found; however, as 89 polymorphisms were tested this was the expected outcome by chance. In VEGF and VEGFR2, we found two SNPs associated with glioblastoma survival, but they could not be confirmed in the separate dataset, and due to multiple testing, were considered to be false positives. Among the DNA repair genes, we found nine SNPs in three genes-MSH2, RAD51L1 and RECQL4-associated with glioblastoma survival after confirmation and adjustment for age, sex, country, and treatment. After adjusting for multiple testing, one SNP in MSH2 and one in RECQL4 remained significant. Conclusions: Our studies provide additional knowledge to the aetiological and prognostic factors important for glioma, emphasising the possible importance of immune function mechanisms. We found limited evidence for the role of genetic variants in glioma progression genes, and some for DNA repair variants as prognostic factors for glioblastoma survival.

Full textAbstract:
Les planàries d'aigua dolça s’han convertit en un bon model per estudiar la regeneració a nivell genètic i molecular, gràcies a la seva capacitat de reconstruir qualsevol fragment danyat a conseqüència d’una amputació, des de qualsevol eix corporal i formar un nou organisme adult en un termini de temps molt curt. Al mateix temps, durant l’estadi adult en l’absència d’una ferida, les planàries són capaces de reemplaçar les cèl•lules diferenciades dels teixits vells mitjançant una proliferació i diferenciació constant de les cèl•lules mare o neoblasts.
Tenim al nostre abast un ampli coneixement sobre diverses rutes de senyalització que controlen l’estricte procés de la regeneració en les planàries. D’altra banda, avui dia encara es desconeix la funció d’algunes de les vies principals i queden molts elements desconeguts per entendre el fenomen de la regeneració. En aquesta tesi doctoral, hem pogut analitzar la funció concreta de la via dels EGFR, sobretot durant la formació del blastema i la regulació del creixement i la diferenciació de les noves estructures anteriors. Mitjançant estudis funcionals a través de la tècnica d’interferència de l’ARN (ARNi) dels tres EGFR identificats, hem observat la participació d’aquesta via en múltiples processos biològics durant la regeneració de les planàries i la homeòstasi. Smed-egfr-1 és necessari per a la regeneració de les cèl•lules pigmentàries dels ulls i la faringe. A més a més, el seu silenciament ocasiona una clara hiperproliferació i la formació d’uns bonys dorsals característics, tant en animals intactes com regenerants. D’altra banda, no es manifesta cap efecte evident després de silenciar Smed-egfr-2. Finalment, podem concloure que Smed-egfr-3 és necessari per la formació del blastema i per la diferenciació de determinats tipus cel•lulars, generalment neuronals.
En aquesta tesi ens hem centrat sobretot amb l’estudi del Smed-egfr-3. Amb l’objectiu d’identificar possibles gens diana d’aquest gen i caracteritzar la funció de la via dels EGFR en més detall durant la regeneració de les planàries, hem utilitzat l’eina DGE (“Digital Gene Expression”), que ens permet comparar el transcriptoma dels animals on s’ha silenciat un gen d’interès (en el nostre cas, Smed-egfr-3) amb el dels controls. Així, a partir d’anàlisis del DGE hem pogut conèixer i quantificar l’expressió de possibles gens diana regulats (tant “up” com “down-regulated”) per la via dels EGFR; un d’aquests gens “downregulated” després d’inhibir Smed-egfr-3 és l’egr-4, un membre de la família gènica dels “early growth response”.
egr-4 s’expressa majoritàriament en el sistema nerviós central i s’indueix ràpidament després de qualsevol tipus de ferida. El seu silenciament inhibeix la regeneració anterior, mostrant defectes durant la formació dels blastemes anteriors, però sense afectar la regeneració posterior. Aquests organismes tractats exhibeixen uns ganglis cefàlics més petits o fins I tot en alguns casos absents. La diferenciació d’altres tipus cel•lulars presents en la regió anterior també es mostren alterats després de silenciar egr-4. Tot i així, l’expressió primerenca dels determinants de la polaritat que intervenen en el restabliment de la polaritat anterior es mostren inalterats.
Experiments simultanis del silenciament d’egr-4 i elements de la via Wnt/beta-cat revelen que egr-4 és necessari per la diferenciació del primordi del cervell. A més a més, els resultats d’aquests experiments suggereixen que egr-4 promou la regeneració cefàlica inhibint l’activitat de beta-catenin en condicions normals. A partir dels resultats obtinguts en aquesta tesi suggerim que egr-4 és un dels primers gens coneguts necessaris per la diferenciació del primordi del cervell durant la regeneració de la planària.
En resum, suggerim una relació entre la diferenciació primerenca del cervell i la correcta progressió de la regeneració del cap en les planàries, que podria estar regulada gràcies a l’activació del gen egr-4 a través de la via EGFR, concretament Smed-egfr-3.During freshwater planarians regeneration, polarity and patterning programs play essential roles in determining whether a head or a tail regenerates at anterior or posterior-facing wounds. This decision is made very soon after amputation. The pivotal role of the Wnt/beta-•catenin and Hh signaling pathways in re-establishing anterior4 posterior polarity has been well documented. However, the mechanisms that control the growth and differentiation of the blastema in accordance with its anteriorposterior identity are less well understood. Conserved signa ling pathways play important roles in morphogenesis in all animals. One such pathway is the epidermal growth factor receptor (EGFR) pathway, which regulates multiple biological processes including cell proliferation, differentiation, apoptosis and cell survival. In this thesis, we show that silencing of Smed-egfr4 3, a planarian homologue of epidermal growth factor receptors, impairs regeneration and blastema growth in these organisms, probably by disrupting cellular differentiation. In order to better characterize the function of the EGFR signaling pathway during planarian regeneration, we conducted "Digital Gene Expression" analyses to identify putative target genes of Smed-egfr-3. One of the isolated candidate genes that is downregulated after silencing Smed-egfr-3 is egr-4, a member of the early growth response gene family. egr-4 is mainly expressed in the central nervous system and rapidly induced after different types of injury. While early egr-4 expression after injury is independent of EGFR signa ling, it becomes Smed-egfr4 34 dependent from the second day of regeneration. Functional analyses based on RNA interference (RNAi) reveals that egr-4 is required for head regeneration but not for posterior regeneration; egr-4 silencing impairs the formation of anterior blastemas; these animals exhibit either small cephalic ganglia or a total absence of new brain tissue. Single and combinatorial RNAi to target different elements of the Wnt/beta-•catenin pathway, together with expression analysis of brain4 and anterior4 specific markers, reveal that egr-4 is necessary for the brain primordia differentiation in the early stages of regeneration and it appears to antagonize the activity of the Wnt/~-catenin pathway to allow head regeneration. Our results suggest that a conserved EGFRjegr pathway plays an important role in cell differentiation during planarian regeneration and indicate an association between early brain differentiation and the progression of head regeneration.

Full textAbstract:
Electronic medical records (EMRs) or electronic health records have been in use for years in hospitals around the world as a time-saving system for patient record keeping. Despite its widespread use, some physicians disagree with the assertion that EMRs save time. The purpose of this study was to explore whether any time saved with the use of the EMR system was actually devoted by doctors to patient-care and thereby to improved patient-care efficiency. The conceptual support for this study was predicated employing the task-technology fit theory. Task-technology theorists argue that information technology is likely to have a positive impact in individual performance and production timeliness if its capabilities match the task that the user must perform. The research questions addressed the use of an EMR system as a time-saving device, its impact on the quality of patient-care, and how it has influenced patients? access to healthcare in Nigeria. In this research, a comparative qualitative case study was conducted involving 2 hospitals in Nigeria, one using EMRs and another using paper-based manual entry. A purposeful sample of 12 patients and 12 physicians from each hospital was interviewed. Data were compiled and organized using Nvivo 10 software for content analysis. Categories and recurring themes were identified from the data. The findings revealed that reduced patients? registration processing time gave EMR-using doctors more time with their patients, resulting in better patient care. These experiences were in stark contrast to the experiences of doctors who used paper-based manual entry. This study supports positive social change by informing decision makers that time saved by implementing EMR keeping may encourage doctors to spend more time with their patients, thus improving the general quality of healthcare in Nigeria.

Full textAbstract:
Health information technology (HIT), which includes electronic health record (EHR) systems and clinical data analytics, has become a major component of all health care delivery and care management. The adoption of HIT by physicians, hospitals, post-acute care organizations, pharmacies and other health care providers has been accepted as a necessary (and recently, a government required) step toward improved quality, care coordination and reduced costs: “Better coordination of care provides a path to improving communication, improving quality of care, and reducing unnecessary emergency room use and hospital readmissions. LTPAC providers play a critical role in achieving these goals” (HealthIT.gov, 2013).
Though some of the impacts of evolving HIT and EHRs have been studied in acute care hospitals and physician office settings, a dearth of information exists about the deployment and effectiveness of HIT and EHRs in long-term and post-acute care facilities, places where they are becoming more essential. This dissertation examines how and to what extent health information technology and electronic health record implementation and use affects certain measurable outcomes in long term and post-acute care facilities. Monthly data were obtained for the period beginning January 1, 2016 through June 30, 2017, a total of 18 months. The level of EHR adoption was found to positively impact hospital readmission rates, employee engagement, complaint deficiencies, failed revisit surveys, staff overtime (partial EHR), staff turnover rate (full EHR) and United States Centers for Medicare and Medicaid Services (CMS) Five Star Quality score. The level of EHR adoption was found to negatively impact CMS Five Star Total score, staff retention rate (full EHR) and staff overtime (full EHR group higher than partial EHR).

A two-step model order reduction method is investigated in order to overcome problems of certain one-step methods. Not only optimal combinations of one-step reductions are considered but also the selection of a suitable intermediate dimension (ID) is described. Several automated selection methods are presented and their application tested on a gear box model. The implementation is realized using a Matlab-based Software MORPACK. Several recommendations are given towards the selection of a suitable ID, and problems in Model Order Reduction (MOR) combinations are pointed out. A pseudo two-step is suggested to reduce the full system without any modal information. A new node selection approach is proposed to enhance the SEREP approximation of the system’s response for small reduced representationsMehrschrittverfahren der Modellreduktion werden untersucht, um spezielle Probleme konventioneller Einschrittverfahren zu lösen.

Full textAbstract:
The reduction of fuel consumption and the reduction of toxic emissions are the main goals of research and development in the area of internal combustion engines. The use of exhaust gas recirculation (EGR) to come further in that direction is today an established method for diesel engines. EGR reduces the emissions of nitrogen oxides with a low penalty in fuel consumption. The increasingly hard regulations on emissions put high pressure on the manufacturers to improve these systems. The present work aims at increasing the knowledge in the area of EGR. Two of the main challenges when applying EGR are addressed, efficiency and mixing. The efficiency of the EGR-system is analyzed, focusing on keeping the fuel penalty low for a given EGR-rate. Different layouts of the EGR system are studied and compared regarding their stationary and transient properties. Exergy analysis is used to show the potential for improvement in different system components. In the same time, exergy analysis as a tool is introduced and compared to energy analysis of a system. The usefulness of exergy analysis of the entire gas exchange is shown by the example of a heavy-duty diesel engine. The problem of EGR and air mixing is approached by a detailed study of the mixing process in a heavy-duty diesel engine. Different methods for the measurement of EGR distribution are presented and compared. Additionally, the possibility to predict the mixing effects by 1-D and 3-D simulation is assessed. It is shown that the mixing between air and EGR is highly dependent on the pulsating nature of the flow. The EGR is shown to be transported in packets in the air flow. This leads to the conclusion that mixing not only at the mixing point, but also mixing in flow direction needs to be optimized, as the distribution of EGR between the cylinders is dependent on the timing between the passage of the EGR packets and the valve opening time.QC 20140203

Full textAbstract:
In ESL writing, a controversy has existed on whether or not an assignment plays an important role when students produce their writings. Plausible arguments have been also made on the matter of amount of information given in a writing assignment. But so far, there have been no convincing data to show a favor of either side in any case.This study is designed to examine the importance of assignment and the relationship between information load and the quality of ESL student writings by analyzing compositions written by ESL students. For the collection of data, 150 students who were randomly selected from two Korean universities. They were asked to write an essay in response to three different types of writing assignments in information load and topic kind.The data were analyzed by two well trained ESL teachers with the method of holistic evaluation. The data were evaluated in nine areas of quality with a binary scale (Yes and No) and in general quality with a 1 to 6 scale. The result of data evaluation was analyzed statistically using SPSS-X. Cross tabulations were used to check for relationship between information load and general impression score, between information load and binary question scores, and between binary question scores and general impression scores. Regression techniques were used to characterize the significant relationships. In performing all calculations, a paper's score will be the sum of the individual graders' scores.The results of data analysis demonstrate that ESL students prefer a subjective topic despite the level of information load. Nevertheless, their preference is not directly related to the quality of their writings. ESL students produce higher quality of writings as they are given less information. Finally, the importance of an assignment in ESL writing classes is supported by the marking of students' higher scores in dichotomous questions.The study also discusses problems and causes of difficulties, in Korean ESL, for utilizing the method of writing education as a means of teaching the English language. The study also points out the importance of a teacher training program and suggests variables which should be considered for producing a better quality teacher training program in the Korean ESL situation.Department of English

O objetivo geral do trabalho consistiu em apresentar um estudo comparativo entre o crédito rural formal e a proposta da EFF, como um novo instrumento de financiamento agrícola no Brasil. Quanto à metodologia empregada, trata-se de pesquisa exploratória, de natureza qualitativa, com dados obtidos através de pesquisas documental e bibliográfica, e de entrevistas, além da observação participante. Os resultados confirmam a possibilidade de financiar a atividade agropecuária utilizando como fonte de recursos o mercado financeiro, através da EFF. Foram feitas duas análises da EFF, uma nas condições da época em que foi feita a proposta e outra nas condições de dezembro de 2001. Na época da proposta o seu custo era próximo ao do Crédito Rural formal para o produtor rural - 0,8625% ao mês contra os 0,7015% ao mês do Crédito Rural formal -, menor para o Governo - 4% contra os 10% do Crédito Rural formal - e permitiria 2,5 vezes mais alavancagem de recursos para o setor rural. Nesta análise, concluiu-se que a equalização de 4% era adequada, pois tornava semelhantes os custos para o produtor rural nas duas modalidades de crédito. Nas condições de dezembro de 2001, embora mantivesse menor custo para o Governo e mais capacidade de alavancar recursos para o setor rural, a elevação das taxas de juros no mercado financeiro tornou o seu custo para o produtor rural 1,6 vez maior do que o Crédito Rural formal, inviabilizando o instrumento para a atividade agropecuária. Nesta análise, concluiu-se que a equalização de 4% não era adequada, pois não tornava semelhantes os custos para o produtor rural nas duas modalidades de crédito. Haveria necessidade, portanto, de equalizações variáveis para a EFF, acompanhando as taxas de juros do mercado e mantendo seus custos para o produtor rural próximo aos do Crédito Rural formal, como forma de torná-la viável. Observou-se que seria vantajoso para o Governo, pois também os seus custos com o Crédito Rural formal oscilam com as taxas de juros do mercado financeiro. A equalização variaria, então, conforme a taxa de juros do mercado e as intenções do Governo de incentivar mais ou menos a atividade. Através desse sistema, o Governo poderia determinar quanto investiria na equalização de taxas do Crédito Rural e manteria a situação sob controle, pois, ao contrário do Crédito Rural formal, conheceria previamente os seus custos. Para a implantação da EFF seriam necessárias apenas adaptações a documentos já existentes, que inclusive já foram estudadas pelo Sindicato Rural de Londrina. As conclusões do estudo foram que a EFF viabilizaria o financiamento da produção agropecuária com recursos do mercado financeiro, seria menos dispendiosa para o Governo, alavancaria mais recursos para o setor rural, permitiria que o Governo mantivesse maior controle sobre os gastos com equalização do Crédito Rural e não admitiria prorrogação de dívidas.

This paper seeks to resolve the biggest problem with hearing aids, their physical fit. By digitally scanning the ear canal and taking the dynamics of the ear into account the performance and comfort of a hearing aid can be greatly improved. Current optical techniques for 3-D imaging are too expensive to be implemented in the ear canal for the purpose of custom fitted hearing aids. A new absorption based optical technique is introduced, which is capable of generating three dimensional maps of an ear subjected to a varying pressure. Specifically a hearing aid can be constructed with allowances for the compliance of the ear and the distortions associated with jaw movement. It is shown that the information that can be captured with this new technique will be of value toward improving hearing aids, and that the hearing aid industry is ready to take advantage of a digital scanner. A one dimensional calibration was made, and qualitative 3-D data is shown. The imaging technique was implemented with much lower cost equipment then would be needed by other 3-D techniques such as interferometry. A technique for the laboratory manufacture of brushed on fluorescent balloons was presented that are suitable to be used by this imaging technique to measure the dynamics of the ear. The bulk compliance of a human ear in vitro was measured with a laboratory fabricated balloon.

Full textAbstract:
Vår uppdragsgivare Banverket efterfrågade en utvärdering av elektronisk fakturahantering(EFH) vid Banverket som infördes för cirka två år sedan. Det finns några olika verktyg för EFH, skanning av pappersfakturor är ett av de verktygen som Banverket använder för att hantera pappersfakturor från olika leverantörer. Vårt mål med uppsatsen var att analysera vilken effekt användningen av EFH får för Banverket.I vår analys studerades effekter av det införda systemet för elektronisk fakturahantering. Uppsatsen har gjorts med hjälp av en kvalitativ undersöknings metod, analysmetoden FA/SIM samt litteraturstudier inom ämnet. Vi har intervjuat personal vid Banverket Produktion och Banregioner i Malmö samt Stockholm. Vi har även intervjuat personal vid HK, Projektering och Telenät i Borlänge.Efter vår analys har vi kommit fram till att det finns stora ekonomiska vinster med elektronisk fakturahantering, men även vinster som inte är direkt mätbara. De viktigaste effekterna är att inga fakturor kommer bort efter de har skannats in och systemet har hela tiden reda på var i flödet fakturan befinner sig, det vill säga bättre kontroll har vunnits. Genom införandet av EFH har flera arbetsmoment försvunnit eller automatiserats och hanteringen av fakturor har förenklats, vilket bidrar till mindre kostnader för hantering av fakturor. Med EFH behöver användarna inte ta kopior av fakturor eftersom de hela tiden finns i systemet. När det gäller minskad dröjsmålsränta har vi kommit fram till att Banverket bör ha minskat kostnaderna för dröjsmålsränta.

Full textAbstract:
The use of electronic medical records (EMRs) has yet to reach its potential for information visualization and achieve corresponding expected outcomes. Current EMR systems show numerous health data with large amounts of texts, which are sometimes integrated in various tables. This type of presentation presents difficulties in promptly determining medical conditions or quickly finding desired information given the volume of texts that needs to be read. Amid these problems, researchers and developers have not explored the creation of easy and intuitive user interfaces for visualizing EMRs.
To bridge the gap between current EMR and ideal EMR systems, we propose a prototype web-based pictorial visualization system that can be used by both patients and doctors. The system allows spatial interactivity through representations of human body images (front and back views) and temporal interactivity through interconnected time axes. Medical histories are classified using 11 physiological systems to enable efficient browsing of selected information. This classification enables physicians to quickly understand patients’ health conditions and accordingly make medical decisions, which are useful in emergency rooms and intensive care units.

It draws on the finding of ten interviews with student-teachers from one of the higher educational colleges in Kuwait. Students were asked to describe how they perceive EFL writing and methods of teaching and learning practices in their EFL writing classrooms. They were invited to discuss the nature of their teachers’ role in their classrooms and assess the extent to which that role enhanced or undermined their attitudes to EFL writing. Students discussed how they felt about EFL writing and their teaching practices. They discussed ways in which their perceptions of EFL writing could be enhanced and explained how their teaching practices influenced their views of themselves as writers. In the literature, there are no theories for L2 writing to date and L2 researchers have tended to assume that the models of L1 would apply equally to L2 writers, with appropriate modifications. This, it is argued, is not necessarily the case as cultural and language differences between L1 and L2 create difficulties that are not accounted for by L1 research, as L2 writers use their identity and their way of making meaning when they write in L2. The study addresses the gap in L2 writing literature, and more research is needed to understand how to support L2 writers in achieving writing fluency. This research suggests that change is needed in pedagogical practices in the teaching of EFL writing. EFL writing teachers in this study demonstrated little awareness, both of how to acknowledge their students’ out-of-school experiencs of writing and of writing as a social practice. The study recommends that the teaching of writing takes more account of the ‘writing process’ approach, with attention given to pre-writing activities and to revision processes, and that more attention is paid to genres in writing, as socially-constructed forms of meaning-making. It also recommends that teacher feedback is developed to be more purposeful and formative. Writing needs implicit learning and intensive practice and it cannot be acquired like speaking. Through learning EFL learners will be more familier with the structure of EFL language and they will understand how use this structure to acheive different social purposes in particular context of use. Well-rained EFL writing teachers will have the ability to help EFL learners write more efficiently. Thus, this research suggests that the students’ pre-service training programme and teachers’ in-service professional developmental programme for EFL writing need to be seriously improved to cope with the social needs of their students, the needs of their society and the needs of developing education internationally. EFL writing needs to be viewed as a vital communicative medium and students should be taught in a way that helps them interact with others by that medium. This research recommends further studies to explore methods of teaching and learning EFL writing and EFL in general to develop a strong voice in debate, to listen to the voice of EFL students, to enhance the methods of teaching practices, and to increase students’ self-efficacy in their ability to be efficient in their EFL writing in particular, and EFL in general.

Wohlman, Katharine Jane. "Ear-tudes: an ear training method for the collegiate tubist." Diss., University of Iowa, 2013. https://ir.uiowa.edu/etd/2662.
Full textAbstract:
Traditionally, collegiate ear training classes in the United States are comprised largely of notation-based exercises and assignments, administered to small groups by a single teacher. Aside from the piano, instruments generally are not used during ear training classes, de-emphasizing the perceived correlation between students' aural skills development and their progress as instrumentalists.
By studying the history of music education, and examining current aural skills pedagogy, the author has found that common practice often relies on notation-based tasks as a measurement of success, despite the fact that research supports the effectiveness of aural-based learning.
In order to encourage a better understanding of pitches and rhythms, the author composed fifteen original etudes ("Ear-tudes") for tuba with accompanying drills. Before revealing each Ear-tude, the instructor leads the student through related drills. Each of the Ear-tudes focuses on a particular interval, scale-type, rhythmic, or tonal challenge, within a variety of meters, tempi, and styles, all of which are suitable for the typical first year tuba student. This method provides an innovative way for tuba teachers to integrate ear training into their instruction, alongside a new collection of etudes designed specifically for freshman students.

The study aimed at mapping the types of language activities of two CD-ROMs, one that accompanies the EFL/ ESL coursebook Interchange Third Edition 1 and one that accompanies the EFL/ ESL coursebook Touchstone 2. To achieve this aim, a framework of types of language activities, based on Hughes and Weir, was created. The analysis of the language activities of the CDs consisted of identifying the main features of each activity, comparing them to the features of the activity types described in the framework and finally, categorizing each activity of each CD as one of the activity types of the framework. The results of the analysis showed that the framework was insufficient because some activities in the CDs did not fit any of the types listed. Also, the results showed that Interchange CD-ROM offers more variety in terms of types of language activities, even though there are more activities in Touchstone CD-ROM. Another finding is that in spite of the variety of types of activities, there are an expressive number of Multiple choice activities in Interchange. Finally, neither of the CDs offers writing activities.
Este estudo teve como objetivo mapear os tipos de atividade de língua encontrados em dois CD-ROMs, um que acompanha o livro didático de inglês como língua estrangeira Interchange Third Edition 1 e outro que acompanha o livro didático de inglês como língua estrangeira Touchstone 2. Para atingir este objetivo, uma taxonomia de tipos de atividades de língua, com base em Hughes e Weir, foi criada. A análise das atividades de língua dos CDs consistiu da identificação das principais características de cada atividade, da comparação dessas características com as dos tipos de atividade descritos na taxonomia e finalmente, da categorização de cada atividade dos CDs como pertencente a um certo tipo de atividade dentre aqueles listados na taxonomia. Os resultados da análise mostraram que a taxonomia foi insuficiente porque algumas atividades encontradas nos CDs não puderam ser encaixadas em nenhum dos tipos listados. Além disso, os resultados mostraram que o CD-ROM da série Interchange oferece uma variedade maior de tipos de atividades, apesar de haver mais atividades no CD da série Touchstone. Outra conclusão é que apesar da variedade encontrada na série Interchange, há um expressivo número de atividades de múltipla escolha. Finalmente, nenhum dos CDs traz atividades de produção escrita.

Full textAbstract:
Electron paramagnetic resonance (EPR) is a spectroscopic technique sensitive to unpaired electrons present in paramagnetic species such as free radicals and organometallic complexes. Electrochemistry (EC) is an interfacial science, where reduction and oxidation processes are studied. A single electron reduction or oxidation generates a paramagnetic species with an unpaired electron, thus making EPR a valuable tool in the study of electrochemical systems. In this work a novel electrochemical cell was designed and developed to be used with a specific type of EPR resonator, called loop gap resonator (LGR). After building and characterising the performance of the EC-EPR setup, it was adapted for quantitative measurements in electrochemical EPR (QEC-EPR). Thus, for the first time, the technique of EC-EPR has been fully characterised for analytical work, opening possibilities to study electrode reactions quantitatively with accuracy and precision not obtained before, as demonstrated in Chapter 8 of this thesis.

Full textAbstract:
Hearing loss is a very common birth defect. However, current hearing screening does not provide adequate specificity. Tympanometry is a potential hearing-screening tool that is specific to conductive hearing loss, but the tympanograms of newborns are currently not standardized and not well understood. Finite-element models of the newborn ear canal and middle ear are developed and their responses to the tympanometric probe tone are studied. Low-frequency and dynamic simulations are used to model the ear's response to sound frequencies up to 2000 Hz. Material properties are taken from previous measurements and estimates, and the sensitivities of the models to these different parameters are examined. The simulation results are validated through comparison with previous experimental measures. Finally, the relative admittances of the ear canal and the middle ear at different frequencies are examined and implications for the interpretation of newborn tympanometry are discussed.La perte d'audition est une anomalie congénitale très courante. Toutefois, le dépistage auditif actuel n'est pas spécifique. La tympanométrie est un dépistage auditif potentiel qui aide à dépister la surdité de transmission, mais les tympanogrammes des nouveau-nés ne sont pas bien compris ou standardisés. Deux modèles d'éléments finis ont été développés: l'un pour le conduit auditif des nouveau-nés, et l'autre pour l'oreille moyenne. Leurs réponses au ton de sonde tympanométrique sont étudiées. Les simulations quasi-statiques et dynamiques sont utilisés pour modeler la réponse de l'oreille aux fréquences de son jusqu'à 2000 Hz. Les propriétés matérielles sont prises des mesures et des estimations précédentes, et les sensibilités des modèles à ces différents paramètres sont examinées. Les résultats des simulations sont validés par la comparaison avec les mesures expérimentales précédentes. Enfin, les impédances relatives du canal externe de l'oreille et de l'oreille moyenne aux fréquences différentes sont examinées et les implications pour l'interprétation de la tympanométrie du nouveau-né sont discutées.

A forte expansão do setor sucroenergético na região noroeste, em uma região caracterizada pela pecuária e fruticultura, motivou a realização deste estudo para avaliar a expansão da cana de açúcar e os impactos sociais e econômicos, em municípios pertencentes aos Escritórios de Desenvolvimento Rural de Fernandópolis, Jales e Votuporanga, localizados na região noroeste do Estado de São Paulo. Foram entrevistados representantes das prefeituras dos municípios com usinas, para analisar os impactos (socioeconômicos e ambiental) ocasionados após a instalação da agroindústria da cana. Foram levantados e analisados os seguintes indicadores socioeconômicos: População residente urbana e rural, o Índice da Federação das Indústrias do Estado do Rio de Janeiro- FIRJAN de Desenvolvimento Municipal (IFDM), Produto Interno Bruto per capita (PIB per capita), o Índice de Gini e vínculo empregatício. Para a análise da viabilidade econômica do cultivo da cana de açúcar foram determinados os custos, a lucratividade, o Valor Presente Líquido (VPL), a Taxa Interna de Retorno (TIR) e o Período de Recuperação do Capital (Payback Period). Assim, observou-se que as principais mudanças positivas foram geração de empregos, aumento de renda da população, movimentação do comércio local e arrecadação de impostos. Problemas na área ambiental com maior toxidez nas outras culturas através da deriva de produtos fitossanitários, aumento da população da mosca de estábulos, diminuição de áreas de plantio de grãos e pastagens, e desgaste das rodovias devido ao excesso peso do tráfego de caminhões. Os indicadores sociais mostraram que a população urbana expandiu para todos os municípios dos EDRs de Votuporanga e de Jales (com exceção do município de Aparecida D’Oeste), e ocorreu uma redução no IFDM consolidado para os três EDRs estudados. Em relação ao PIB per capita, no geral notou-se que a média dos municípios com usinas no EDR de Votuporanga se destacaram com crescimento econômico de 74,97%, no entanto nos EDRs de Fernandópolis e Jales apresentaram índices inferiores a 2,29%. O COT na implantação do canavial foi de R$6.772,82/ha e nos custos de produção dos cinco cortes, observou-se que a operação com CCT apresentou o maior dispêndio. A análise econômica mostrou lucratividade em todos os cortes para o COT e para os três primeiros cortes para o CT, considerando o preço médio de R$84,15 a tonelada, e produtividade média variando de 106,5t/ha (1º corte), a 65,77t/ha (5º corte). O capital investido na produção de cana para indústria retorna ao fornecedor no 3º corte (CT) e no 2º corte (COT), os VPL foram positivos e as TIR para ambos os custos foram maiores que o custo do capital. A produção de cana de açúcar para indústria na região noroeste paulista apresenta resultados economicamente favoráveis, mas o produtor precisa exercer uma gestão eficiente do seu negócio, gerenciamento dos custos que lhe permita tomar decisões baseadas nos mesmos, principalmente na renovação dos canaviais em que o investimento na atividade é grande. Os resultados socioeconômicos obtidos não permitem afirmar que os avanços nos indicadores estudados se devem a presença de usinas em alguns municípios.
The purpose of this study was to evolute the expansion of the sugarcane and its social and economic impacts, in municipalities of the Rural Development Offices from Fernandópolis, Jales and Votuporanga, located in northwest of the State of São Paulo. This study was motived by the Strong expansion of the sugar energy sector in a region normally characterized by catlle raising and fruit growing. The City Halls of those Municipalities with sugarcane mills in theseRural Developmente Offices (EDRs- Escritorio de Desenvolvimento Rural) were interviewed to analyse the socioeconomic and environmental impacts caused after the installation of sugarcane industry. The following socioeconomic indicators were collected and analyzed: urban and rural residente population, the index of Federation of the Industries from the State Rio de Janeiro (FIRJAN), Municipal Development (IFDM), Gross Domestic product per capita (PIB per capita), Gini Index and employment relationship. Analysis was gathered on the economic feasibility of sugarcane cultivation, the costs, profitability, Net Present Value (VPL- Valor Presente Líquido), Internal Rate of Return (TIR- Taxa Interna de Retorno) and Payback Period The main positive changes were the generation of jobs, the increase of population’s income, the movement of local commerce and the collection of taxes. Problems in environmental area with greater toxicity through the drift of phytosanitary products, increase of the fly population of the stables, reduction of planting grain area and grazing areas and wear and precariousness roads due to the excess weight of trucks traffic. The social indicators showed that the urban population expanded to all EDR cities from Votuporanga and Jales (except Aparecida D’Oeste city), and there was a reduction in consolidated IFDM for the three EDRs studied. Regarding GDP per capita (PIB), in general it was noted the average of municipalities with sugar cane plants in EDR from Votuporanga stood out with economic growth of 74,97%, however EDR from Fernandópolis and Jales presented indexes lower than 2,29%. COT in the planting of the sugar cane fields was R$6.772,82/ha and in the production costs of five cuts, the operation with CCT presented the highest expenditure. The economic analysis showed profitability in all cuts to TOC and to the first three cuts to CT, considering the average price of R$84,15 per ton and an average productivity ranging from 106,5t/ha (1st cut) to 65,77 t/ha (5th cut). The capital invested in the production of sugar cane for industry returns to the supplier in the 3rd cut (CT) and in the 2nd cut (COT), the VPL were positive and the TIR for both costs were higher than the capital cost. The production of sugar cane for industry in northwest of São Paulo State presents economically favorable results, but the producer needs to exercise an efficient management of his business, cost management that allows him to make decisions based on them, especially in the sugar cane fields renovation, where the investment in the activity is big. The socioeconomic results obtained do not allow to affirm the advances in the indicators studied are due to the presence of sugarcane plants in some municipalities.

Barlow, Lisa. "The effect of non-native speaker accent on EFL students' listening comprehension." Thesis, University of Exeter, 2009. http://hdl.handle.net/10036/92399.
Full textAbstract:
With the increasing demand for English language proficiency in today’s global environment, comes a need for trained English as a Second or Foreign Language (ESL/EFL) teachers. Many countries such as the United Arab Emirates (UAE) are establishing bachelor and master degree programs in the field of Teaching English to Speakers of other Languages (TESOL). The majority of students in these programs are nonnative speakers of English. While these new graduates should be able to fill the growing demands for English teachers in tertiary and non-tertiary institutions within the UAE, they and other experienced nonnative English speaking teachers (NNEST) are often not hired. Most often this is due to a nonnative speaker bias, the view that only native English speaking teachers are better suited to teach English. This bias extends particularly to the teaching of oral and aural skills. There is a belief that accented English is difficult for students to comprehend especially in academic listening which implies that nonnative teacher accent can hinder ESL/EFL student listening success. However, current research has not provided empirical evidence to verify or disprove this opinion. Current research on nonnative speakers and listening comprehension has been based on teacher and student self-perceptions and attitudes towards nonnative speaking teachers (Butler, 2007; Flowerdew, 1994; Friedrich 2000; Huang, 2004; Major et al., 2002; McKenzie, 2008; Moussu, 2002). However, there is little quantitative data to support if and how these attitudes and perceptions may or may not correlate to EFL student listening performance. This thesis will attempt to resolve this deficiency. Another issue this thesis will undertake which has not been examined widely is the effect of nonnative speaker accent on academic listening. Various studies have been conducted on student difficulty in comprehending academic lectures from native and nonnative speakers (Ferris & Tagg, 1996; Flowerdew & Miller, 2005; Huang, 2004; Lynch, 1994; Powers, 1985; Richards, 1983; Vogely, 1995). Yet, currently, the literature is sparse on the influence of nonnative speaker accent as a factor, or effect, in the listening comprehension of L2 students’ understanding of academic lectures. Further, existing research in NNESTs is also missing empirical or quantitative evidence which proves or disproves the prevailing theory that native inner circle English accents are significantly better for EFL student academic listening comprehension. Thus, another goal of this thesis is to provide evidence to disprove this assumption. Finally, this research will provide qualitative data to understand how students view accent as it relates to their academic achievement and prospective careers. This thesis will propose new empirical data relating to nonnative speaker accent and listening comprehension in ESL/EFL. It will provide evidence that there is no significant effect of accent on academic listening test scores for EFL students enrolled in a university foundations program at UAE University. In this research, six EFL professionals (from China, Egypt and the USA) and 108 EFL students participated in the study. The female students were between 18-20 years old, from the UAE, and studying at the Under Graduate Requirements Unit at UAE University in Al Ain, UAE. All students responded to a pre-test questionnaire in a Likert scale format. A week later, the students listened to one recording, took a corresponding exam, and answered a post-test survey. Two to three days later, 18 randomly selected students were interviewed. The interviews consisted of open-ended questions. The data were analyzed both quantitatively and qualitatively. Analysis of the quantitative data shows that the majority of participants considered native speakers of English easier to understand, specifically in terms of pronunciation and understandability, but had no opinion as to whether a non-native speaker was easier to understand than a native speaker. As per the listening test scores, there were no significant differences between the six groups of students who had listened to six different speaker accents. Analysis of the interviews shows that students have no bias against nonnative English teachers. In fact, several students favored Arab nonnative English speaking teachers to translate vocabulary and complex ideas from English to Arabic. These students also demonstrated an unrealistic grasp of their need to understand the varieties of English they will encounter in their future workplaces.
