Este trabalho trata do processo de digitação para violão da Ciaccona BWV 1004 (original para violino) de Johann Sebastian Bach (1685-1750). O objetivo foi desenvolver uma digitação de mão esquerda capaz de refletir as intenções musicais do presente autor. Para tal, foi estabelecido um modelo de análise, onde a textura musical é dividida e classificada, com base em referenciais teóricos, como: melódica, harmônica, motívica e polifônica. Ao analisar as digitações usadas em transcrições, e compará-las às desta pesquisa, concluímos que se pode ter autonomia para contestar uma digitação grafada, pois ela reflete nada mais que as decisões do seu autor, sejam musicais ou técnicas. A partir disto, podemos deduzir que elas se alteram conforme as nossas próprias decisões.This work deals with the process of elaborating guitar fingerings for J. S. Bach’s Ciaccona BWV 1004 (original for violin). The aim was to develop a left hand fingering able to reflect the musical intentions of the present author. To this end, a model of analysis was established, in which the musical texture is divided and classified, based on theoretical references, into the following categories: melodic, harmonic, motivic and polyphonic. By analyzing the fingering used on transcriptions, and comparing it with the results of this research, we conclude that we can question a suggested fingering, because it reflects nothing more than the decisions of its author, whether musical or technical. From this we can deduce that they change according to our own decisions.

The compositional technique of cross partitioning is one of Luigi Dallapiccola's most used twelve-tone devices. Through a detailed analysis of three contrapuntal canonic movements from Dallapiccola's Quaderno Musicale di Annalibera, I examine his use of cross partitioning as a motivic tool and as a referential collection. The development of the BACH motive and the derivation of tone-row statements reflects on Dallapiccola's extensive use of cross partitioning and his compositional principles used to achieve a sense of polarity. Upon a preliminary analysis based on set-theory analysis set out by Joseph Straus I draw an interpretive analysis through Alegant's cross partitioning model as well as develop my own set of parameters for interpretation in regards to polarity which is based on intervallic stability.

Texto completoResumen
Back pain is a very common musculoskeletal impairment in most Americans. Average annual occurrence of back pain is reported around 30% of the population and is the most common cause of activity limitation in people younger than 45 years old. Eighty percent of the back pain presents in the lumbar spine. Although this ailment is very prevalent in the American population, there is a lack of empirical evidence supporting the common clinical diagnosis and intervention back pain strategies. The frequency of back pain and the lack of treatment methods were the motivation for this investigation. It is important to better understand spine dynamics during ambulatory tasks of daily activities to identify possible biomechanical mechanisms underlying back pain.
Current biomechanical quantification methods for spine dynamics are either too invasive or not detailed enough to fully comprehend detailed spinal movement. Therefore, a non-invasive but detailed procedure to calculate spine dynamics was developed and tested. In this study, multi-segmented spine dynamics (kinematics and kinetics) were calculated during four activities of daily living (level walking (W), obstacle crossing (OC), stair ascent (SA) and stair descent (SD)).
Our findings suggested an in-vivo multi-segmented spine surface marker set is able to detect different and repeatable motion patterns during walking among various spinal segments. The sacrum to lower lumbar (SLL) joint had the largest range of motion (ROM) when compared to the other more superior joints (lower lumbar to upper lumbar and upper lumbar to lower thoracic). Furthermore, SA task demonstrated more flexion ROM than both W and SD tasks. In addition to task influence, joints at different spine levels also demonstrated different ROMs, where SLL had a greater ROM than upper lumbar to lower thoracic (ULLT) in the transverse plane. Age was found to not significantly affect the segmental spinal ROM or peak angles. The vertical segmental joint reaction forces were different between tasks, where SD yielded larger vertical reaction forces than W.
Overall, findings from this dissertation work were able to show that a multi-segment spine marker system could be an effective tool in determining different spinal dynamics during various activities of daily living.

Texto completoResumen
L'échographie est aujourd'hui l'une des modalités les plus populaires de diagnostic médical. Il permet d'observer, en temps réel, le mouvement des organes qui facilite le diagnostic des pathologies pour des médecins. L'échocardiographie [1, 2], l'imagerie du flux sanguin [3, 4] et l’élastographie [5-7] sont les domaines préférés de l'estimation de mouvement en utilisant l'échographie (en raison de son haut frame-rate).En conséquence, les images avec meilleurs qualités sont nécessaires. . En imagerie cardiaque, le système classique d'imagerie est limité dans la direction transversale (la direction perpendiculaire à celle de propagation). Travaillant sur la formation des images, ce problème peut être résolu en modifiant la façon de formateur de voie afin d'introduire des oscillations transversales (OTs) dans la fonction d’étalement du point (PSF). La technique d’oscillation transversale a montré son potentiel d'améliorer la précision de l'estimation de mouvement local dans la direction transversale (la direction perpendiculaire à celle de propagation). La classique OT en géométrie linéaire, basée sur l'approximation de Fraunhofer, relie la PSF et la fonction de pondération par la transformée de Fourier. Motivé par l'adaptation des OTs en échocardiographie, nous proposons une technique spécifique basée sur la rétro-propagation afin de construire des OTs en géométrie sectorielle. La performance de la méthode de rétro-propagation proposée a été étudiée progressivement, comparée avec la méthode de la transformée de Fourier, par exemple, l'évaluation de la qualité de la PSF quantifié, dans l'estimation de mouvement cardiaque en simulation, et en étude la qualité des PSF visuellement expérimentale. Les résultats quantifiés montrent les OT-images sont mieux contrôlés par la méthode proposée que par le formateur de voie conventionnelle. Une autre méthode, basée sur la décomposition d'onde plane et un principe différent de rétro-propagation, a été présentée. Cette méthode mieux prend en compte la propriété 2D de PSF, en décomposant la PSF dans un ensemble d'ondes planes directionnelle, les rétro-propage à la sonde, en utilisant les résultats de superposition comme excitations, un PSF simulée et conforme fortement au PSF théorique est acquis. En adaptant cette méthode à la géométrie sectorielle, la qualité de la PSF obtenue en face et sur la côté de la sonde est meilleure en utilisant la décomposition en ondes planes à celle de la transformée de Fourier, le travail supplémentaire sera adressé à adapter la décomposition en ondes planes à imagerie sectorielle et l’estimation du mouvementEchography is nowadays one of the most popular medical diagnosis modalities. It enables real-time observation the motion of moving organs which facilitates the diagnosis of pathologies for physician. Echocardiography [1, 2], blood flow imaging [3, 4] and elastography [5-7] are the favorite domains of motion estimation in using of echography (e.g., due to its high frame-rate capacity). Thus the requirements for imaging with high quality are on the primary place. In cardiac imaging, the conventional imaging system is somehow limited in the transverse direction (the direction perpendicular to the beam axis). Working on the image formation, this problem can be addressed by modifying the beamforming scheme in order to introduce transverse oscillations (TOs) in the system point spread function (PSF). Transverse oscillation techniques have shown their potential for improving the accuracy of local motion estimation in the transverse direction (i.e., the direction perpendicular to the beam axis). The conventional design of TOs in linear geometry, which is based on the Fraunhofer approximation, relates PSF and apodization function through a Fourier transform. Motivated by the adaptation of TOs in echocardiography, we propose a specific beamforming approach based on back-propagation in order to build TOs in sectorial geometry. The performance of the proposed back-propagation method has been studied gradually, in comparison with the Fourier transform, such as in evaluation of the quality of PSF, in estimation of simulated cardiac motion and in experiments study, etc. The quantified results demonstrate the proposed method leads to better controlled TOs images than the conventional beamforming. Another method based on plane wave decomposition and a different back-propagation principle has been presented. This method is better taking into account the 2D property of PSF, by decomposing the PSF into a set of plane waves directionally, back-propagating them to the probe, by using the superposition results as excitations, a simulated PSF with high accordance to the theoretical one is acquired. By adapting this method to sectorial geometry, the quality of PSF obtained in front of probe is better using the plane wave decomposition method than that of Fourier relation, but it is limited for the scanning on the side of probe, so the further work will be addressed to adapting the plane wave decomposition method to the complete sectorial imaging

Texto completoResumen
The noted Bach scholar Christoph Wolff and two other researchers made one of the more noteworthy musicological finds of the late twentieth century in 1984, when they first rediscovered and then published MS LM 4708 of the John Herrick Music Library of Yale University. This MS, which was published under the title The Neumeister Collection, contains 82 organ chorales, many previously unknown, by members of the Bach circle. Of those 82 chorales, five pieces appear without attribution and six works have been published that were previously attributed to other composers. Wolff's edition, which lists composers for all 82 chorales, relies largely upon stylistic analysis when assigning attributions for pieces with multiple attributions. This document introduces a new analytic tool that can be used to generate information relevant to questions of authorship in the Neumeister chorales; this important tool is a computer program called MATLAB. MATLAB can compile and tabulate information about the melodic, intervallic, and contrapuntal content of musical compositions by analyzing XML computer files produced by standard music software programs such as Finale or Sibelius. This data then can be used to generate graphs that can be compared between compositions. Such analysis sheds new light upon the musical choices of composers represented in The Neumeister Collection and makes possible more informed judgments about pieces with multiple attributions.

Texto completoResumen
Motion and motor patterns of low back pain (LBP) sufferers have been demonstrated as different compared to those without LBP. The mechanism behind such movement alterations is not well known but is believed to be related to pain. Current biomechanical measurement of lumbar curvature and kinematics has limitations for routine clinical use. The aims of this research were to (1) investigate new motion analysis technology for dynamic lumbar curvature (fibre-optic sensors) and higher order kinematic assessment (inertial sensors) within a clinical environment; (2) determine the effect of pain relief on lumbar curvature, kinematics and muscle function in acute low back pain (ALBP) and chronic low back pain (CLBP) sufferers. Dynamic lumbar curvature was found to be reliably measureable in the clinic. Additional analysis demonstrated that regional curvature, as well as sequencing of curvature change measurement was possible. ALBP sufferers display less peak curvature during flexion and lifting compared to CLBP sufferers and both groups demonstrated the greatest curvature change in the second quartile for flexion and lifting and first for extension. Partial pain relief did not increase curvature in either group, and neither group was more likely to respond to pain relief by increasing curvature or altering sequencing. Higher order kinematics could be reliably and readily indentified in the clinic using inertial sensors. Movement-velocity plots were employed to describe the movement trajectory and irregularity. Multivariate analysis of variance revealed that neither partial pain relief (pre vs post) nor chronicity (acute vs chronic) had any effect on lumbar kinematics. Individuals appeared to exhibit different electromyography profiles. Those individuals with little deviation in muscle activation commonly displayed lower kinematic values. Partial pain relief did not alter the pattern of EMG profile, muscle onset timing or peak amplitude. These results suggest that clinicians should not expect automatic alterations in motion and motor patterns following interventions which target and achieve partial pain relief.

Texto completoResumen
Den 1 januari år 2005 blev det obligatoriskt för EU-medlemmarnas börsnoterade bolag att redovisa enligt IASB:s redovisningsstandard IFRS. Införandet innebar genom IAS 36 att en årlig nedskrivningsprövning av goodwill ersatte årliga avskrivningar av goodwill. I praktiken har IAS 36 gett företagen möjlighet att tolka och därmed tillämpa IAS 36 på olika sätt; en neutral respektive subjektiv användning. Vid en neutral användning sker nedskrivningen av goodwill vid en faktisk värdeminskning av företagets goodwill, medan den subjektiva användningen utgår från företagsledningens egenintresse. Tidigare studier har visat att företagsledningen kommer att utnyttja sin handlingsfrihet om det finns agentbaserade motiv till det. Företagsledningens incitament att agera utifrån sitt egenintresse har förklarats genom agentteorin som beskriver hur separationen mellan företagsledningen och ägarna ger företagsledningen ett informationsövertag och därmed incitament att agera utifrån agentbaserade motiv. Denna studie har därmed undersökt om tre agentbaserade motiv kan förklara nedskrivningar av goodwill enligt IAS 36; (1) andelen goodwill i företaget, (2) resultatets påverkan samt (3) tillträdandet av en ny VD. Denna studie har haft en kvantitativ longitudinell forskningsdesign och har undersökt företag som var noterade på Nasdaq OMX Stockholm mellan åren 2005-2010 och som skrivit ned goodwill. Kvantitativa data har inhämtats från företagens årsredovisningar och använts för att beräkna de variabler som testat hypotesernas förklaringsvärde. Resultaten för hypotes 1 visade att goodwillintensiva företag tenderade att undvika en nedskrivning av goodwill under år 2005. Det sambandet kunde inte visas under senare år. Det samband som visades mellan ett negativt resultat och goodwillnedskrivning i enlighet med hypotes 2 under åren 2005-2007 bör tolkas med försiktighet till följd av få antal observationer. Resultatet för år 2008, då fler observationer fanns att tillgå, överensstämde även med hypotesen. Sambandet kunde dock inte visas för senare år. För hypotes 3 och tillträdandet av en ny VD kunde ett samband utläsas för några år. Däremot kunde inte hela tidsperioden bekräfta ett samband mellan en ny VD och större nedskrivningar av goodwill. De resultat som gavs av hypotes 1 kan möjligtvis förklaras med att aktiemarknaden inte reagerar lika starkt på företagets nedskrivningar av goodwill efter införandet av IAS 36 i och med att verkliga värden är mindre tillförlitliga än historiska värden. Resultaten för hypotes 2 gav inte argument för att ett negativt resultat ger företagsledningen motiv att skriva ned goodwill som en del av big bath accounting. Resultaten i sin helhet indikerar även att finanskrisen inte haft en avgörande effekt på företagens nedskrivningar av goodwill vid ett negativt resultat. Till följd av resultaten i hypotes 3 ifrågasätter denna studie hållbarheten i teorin big bath accounting vid nedskrivningar av goodwill i svenska börsnoterade företag.

Texto completoResumen
The purpose of the study was to quantify the relative contribution of low back flexibility and hamstring flexibility in the sit and reach test item of the AAHPERD Health Related Fitness Test in order to examine the validity of the sit and reach test. Subjects were 100 female students, 13 to 15 years of age in physical education classes. Hamstring flexibility was measured using the Leighton flexometer. Spinal mobility was measured using a tape measure. The sit and reach test was performed according to instructions given in the AAHPERD Test Manual. Data were analyzed using correlation, linear regression, and multiple regression. Conclusions of the investigation were (1) hamstring flexibility is moderately related to the sit and reach test, (2) low back flexibility has a very small relationship to the sit and reach test, and (3) the sit and reach test is an inadequate measure of low back and hamstring flexibility.

Texto completoResumen
Over the last decade, film location tourism has been established as a niche segment in the tourism industry. While this niche has attracted attention from both researchers and marketers alike, not much knowledge has been accumulated about the tourist encounter itself. It is the main purpose of this thesis to research on-site behavioural and experiential aspects of the film location encounter.
For the overall research design, an inductive, comparative case-study approach was implemented. Three cases were selected for this research: The Lord of the Rings locations in New Zealand, The Sound of Music locations in Austria and Star Wars locations in Tunisia. The applied methods are participant observation, image-based data and semi-structured interviews. The data collection was conducted while participating in organised film location tows in order to secure access to the informants.
The first fundamental outcome of this research is that there is no 'film location tourist' as such. People who travel to film locations come from different socio-economic backgrounds, comprise all age groups and possess varying degrees of fandom. The majority of film location tourists, however, have one thing in common, regardless of the underlying movie genre: the longing to connect with the imaginary world of the film by visiting the physical and thus 'real' location places. These places are consumed in two ways: as places of spectacle and as sacred places.
The nature of the location consumption is dependent on a number of factors, including the degree of fandom of the consumers, the attractiveness of the encountered locations, the consistency of the interpretive community, the amount and nature of external distortions and, if applicable, the structure of the location tour. Means of consumption of film locations as spectacle are formal posing, sight recordings and shot re-creations. When experiencing film locations as sacred places, shot re-creations, mental simulations and filmic re-enactments occur. The latter form of consumption can result in a symbiosis between the imaginary and the real place component: the gazing subject becomes the previously (photographed) object.
Regardless of the degree of experiential satisfaction, film location tourists want to bring some of the magic back home. This is achieved not only via mental pictures and physical photographs, but also through souvenirs. These can be off- or on-site. Regarding the latter, these souvenirs are almost holy relics, brought home from a successful pilgrimage and subsequently framed and displayed in an altar-like fashion. The benefits from this are not only self-pride and satisfaction, but also the distinction to other movie fans who have not been able to do the journey themselves. Thus, the person in possession of such a relic gains privileged status amongst peers which in turn raises the satisfaction with the location encounter.
The film location experience cycle comes to a full closure by re-watching the movie. This procedure involves a renewed connection to both the imaginary filmic places as well as the real locations visited. The filmic gaze is extended, as the movie scenes are now seen as part of a real place which extends beyond the filmic sight.
Keywords: Film location tourism - multiple, comparative on-site case study inquiry - film locations as spatial and temporal constructs - the film location tourist encounter - behavioural and experiential interactions with place.

Texto completoResumen
Lumbar spine range of motion (ROM) is conventionally measured using multiple, individual anatomical plane movements. This is unwieldy for clinical research, because it relies on the assumption that a large proportion of subjects will present with the same impairment. The objective of this thesis work, therefore, was to assess the reliability of a novel measure of total lumbar spine ROM, to be used in future studies. We hypothesized that the reliability of this measure would be ≥0.9, so as to meet previously suggested criteria for monitoring individual patient progress. Twenty subjects with chronic low back pain (LBP) were recruited for two testing sessions. At each session, subjects performed 3 series of 8 end-range, randomly ordered lumbar spine movements, at 45 degrees intervals around the full circle, with the help of visual feedback. Lumbar spine motion was acquired using two, 6-degrees-of-freedom electromagnetic motion capture sensors placed on the skin over the spinous processes of the twelfth thoracic (T12) and first sacral (S1) vertebrae. The measure of interest was based on the relative position of T12 in the transverse plane of S1. Two curve fitting approaches - least-squares ellipse and cubic spline - were used to fit a shape to the 8 end-positions of movement in each series. The area of this shape was used to provide a measure of the total ROM, and the centre point to provide a measure of movement distribution and symmetry. Generalizability theory was used to assess the reliability of the area of each shape, and of its centre point in the anterior-posterior and medio-lateral axes of the transverse plane of S1. The index of dependability for the total lumbar spine ROM (area) was excellent (0.94 - 0.95), and moderate-to-excellent (0.59 – 0.91) for its distribution (centre points), with slightly better values achieved with the spline-fitting approach. Analysis of extrapolated data also indicated that similar values would be achieved using 3 repetitions of the task in a single testing session. These results support the use of this novel measure of total lumbar spine ROM in future clinical studies.L'amplitude des mouvements de la colonne lombaire (ou ROM, pour range of motion en anglais) est traditionnellement mesurée à l'aide de multiples mouvements individuels exécutés sur les plans anatomiques. La technique utilisée pour obtenir cette mesure complique la recherche clinique, car elle repose sur l'hypothèse qu'une forte proportion de sujets présente la même déficience. L'objectif de cette thèse était donc d'évaluer la fiabilité d'une nouvelle mesure de mouvement global de la colonne lombaire, qui serait utilisée dans des études futures. Notre étude repose sur l'hypothèse que la fiabilité de cette mesure serait ≥ 0,9; de manière à répondre à des critères préalablement proposés pour suivre les progrès d'un patient unique.Vingt sujets souffrant d'une lombalgie chronique (ou LBP, pour low back pain en anglais) ont été recrutés pour deux séances. À chaque séance, les sujets, aidés d'une rétroaction visuelle, ont effectué 3 séries de 8 mouvements de fin d'étendue de colonne lombaire, à 45 degrés d'intervalle autour d'un cercle complet, et ce, dans un ordre aléatoire. Les mouvements de la colonne lombaire ont été obtenus au moyen de deux capteurs électromagnétiques à 6 degrés de liberté, placés sur la peau au-dessus des apophyses épineuses de la douzième vertèbre thoracique (T12) et de la première vertèbre sacrée (S1). La mesure qui nous intéresse a été calculée d'après la position relative de T12 dans le plan transversal de S1. Deux méthodes d'ajustement de courbe ont été utilisées pour lier les 8 points de fin de mouvement dans chaque série : l'ellipse par les moindres carrés et la fonction spline cubique. L'aire de la forme ainsi obtenue a servi à fournir une mesure de la ROM totale; et le point central, une mesure de la distribution et de la symétrie des mouvements. La théorie de la généralisabilité (en anglais Generalizability Theory) a été employée pour évaluer la fiabilité de l'aire de chaque forme et celle de son point central dans les axes antéro-postérieur et médio-latéral du plan transversal de S1. L'indice de fiabilité était excellent (0,94 – 0,95) pour la ROM globale de la colonne lombaire (l'aire) et allait de modéré à excellent (0,59 à 0,91) pour la distribution des mouvements (points centraux), avec des valeurs légèrement plus élevées pour la méthode d'ajustement par spline. L'analyse des données extrapolées a également indiqué que des valeurs similaires seraient obtenues en utilisant 3 répétitions de la tâche dans une séance unique. Ces résultats appuient l'utilisation de cette nouvelle mesure de la ROM de la colonne lombaire dans de futures études cliniques.

Texto completoResumen
Ce doctorat porte sur un motif visuel qui circule entre les arts : le personnage vu de dos. Par l’entremise de notions que j’ai approfondies ou développées – l’apparaître, l’inévidence, la dorsalité –, j’interroge comment cette posture fait naître une manière d’habiter l’image et le monde, et j’analyse ses implications dans les pratiques artistiques comme dans le champ philosophique et social. Pour mener cette enquête, je me suis inspirée d’un geste d’Aby Warburg, celui de la fabrication d’atlas d’images. La fabrication d’atlas m’a permis de faire apparaître trois modalités expressives du dos qui traversent l’histoire de l’art et du cinéma, et qui se retrouvent au sein de mes planches. J’aborde ces questions dans le premier chapitre de la thèse. Le deuxième chapitre, intitulé « Repli(s) », porte sur ma première planche d’images, consacrée aux personnages de dos qui se dérobent et s’esquivent, exprimant un retrait de la signifiance expressive. Le troisième chapitre aborde ma deuxième planche d’images, dans laquelle je cherche à faire voir une forme d’absorbement mené par le personnage de dos depuis l’âge romantique. Le quatrième et dernier chapitre, intitulé « Exclusion(s) », traite d’une violence faite au sujet. En me penchant sur la représentation des Afro-Américains dans les films de plantation états-uniens, j’explore comment une forme d’exclusion esthétique, sociale et politique s’est fabriquée par la posture de dos. Que nous disent les personnages repliés, absorbés ou exclus en regard de la frontalité qui prévaut encore aujourd’hui ? Les personnages vus de dos présentés dans ma thèse introduisent une dorsalité des représentations et de l’existenceThe research topic addressed in this paper is a visual motif circulating widely among the arts: the figure seen from behind. Through notions that I have been led to further or develop – appearance, inevidence, dorsality, I examine how this posture depicts a way of inhabiting the image and its world, and analyze its implications in artistic practices as well as in the philosophical and social field. In order to carry out this survey, I was inspired by a gesture of Aby Warburg, the creation of atlases of images. Atlas making allowed me to reveal three expressive modalities of the back running through the history of art and cinema, and which are also found within my boards. I address these questions in the first chapter of the thesis. The second chapter, titled "Repli (s)", focuses on my first picture board, devoted to figures from behind who avoid and sneak away, conveying a withdrawal of expressive meaning. The third chapter addresses my second picture board, in which I sought to depict a form of absorption led by the figure from behind since the Romantic Age.The fourth and last chapter, entitled "Exclusion (s)", examine a violence committed upon the subject. By focusing on the portrayal of African-Americans in American plantation films, I try to show how a form of aesthetic, social, and political exclusion has been created by the representation from behind. What are withdrawn, absorbed or excluded characters telling us in view of the frontality that still prevail today? The figures seen from behind, as presented in my thesis, introduce a dorsality of representations and of existence

Texto completoResumen
This dissertation explores how Hollywood, in the years following the creation of the Classification and Ratings Administration (CARA) in 1968, reimagined the "mass audience" in an age of audience fragmentation. Building on Richard Maltby's suggestion that the rating system did not cause "the majors to alter their fundamental assumptions about the nature of film as a commercial commodity," I will show how the industry successfully continued to portray itself as a producer of universal entertainment for an undifferentiated audience. Guaranteeing that all CARA certified films would be rendered "respectable" for its audiences was the key tactic in this strategy. The abandonment of the X through the cooperation of large, vertically aligned and integrated companies has ensured an unusual industrial stability under the mediating regulatory practices of CARA for almost thirty years. In the process of detailing how the studios successfully anticipated and accommodated CARA's requirements for what I term the "incontestable R"---in theory a "restricted" category, but in fact a category permitting all-ages consumption---I explore the consequences that arranging pictures for an R has for Hollywood production practices. By examining the ill-fated attempts to restore the adult category with the NC-17 rating in 1990 and Showgirls in 1995, I demonstrate how the continuing stigmatization of the NC-17 serves the economic interests of its large member distributors at the expense of small independent or unaffiliated distributors and exhibitors.

Texto completoResumen
Low back pain (LBP) is a common health problem that contributes to the high cost of health care. Improvement in trunk range of motion has been considered to be an important factor in ameliorating the symptoms of LBP. Kinesio® taping is a prominent therapeutic modality commonly used in the variety of populations for treating musculoskeletal conditions. However, previous research on the efficacy of Kinesio® taping for LBP is limited. The purpose of this study was to investigate the immediate and short-term effects of Kinesio® taping with the muscle inhibition technique on active trunk flexion range of motion. Twenty-five subjects with no history of LBP in the past 6 months or LBP lasting over six weeks at any point in past were recruited from a Division I athlete population. Each subject underwent two Kinesio® taping trials in a cross-over design with a 7-10 day washout period (placebo application and inhibition technique application), during which several trunk flexion range of motion measurements were made. Subjects wore the tape for 48 hours, and active trunk flexion range of motion was measured at baseline, immediate post-tape application, and 48 hours post-tape application. A significant trial by time interaction was found (F = 9.629; p = 0.002), and follow-up analysis of the inhibition technique trial revealed a significant increase in active trunk range of motion between baseline and 48-hours post-tape. No significant differences were noted in the placebo trial. The findings suggest that the inhibition Kinesio® taping technique may eventually prove to be a beneficial therapeutic modality for improving active trunk flexion range of motion in patients with LBP.

Texto completoResumen
Management and control of the low back pain as an important health problem in the industrial societies necessitates to investigate how the risk of this disease is affected by aging. Since the abnormalities of the lumbopelvic kinematics are related to the existence or risk of low back injuries, the objective of this dissertation was set to find the age-related differences in lumbopelvic kinematics when performing basic trunk motions reaching to range of motion in different anatomical planes.
A cross-sectional study was designed where sixty asymptomatic individuals between 20–70 years old with no confounding health condition, no current or previous highly physically demanding occupation and a body mass index between 22 and 30, were divided in five equally-sized and gender-balanced age groups, and attended two sessions of data collection to perform three repetitions of self-selected slow and fast trunk forward bending and backward return, as well as one left and right lateral bending and axial twist. Following an extensive literature review, the lumbar contribution (LC) to the trunk motion, the mean absolute relative phase (MARP) between the thoracic and pelvic motions as well as variation in MARP under repetitive motions, denoted by deviation phase (DP) were selected and used for the assessment of age-related differences in lumbopelvic kinematics during forward bending and backward return tasks. Lumbopelvic kinematics during the lateral bending and axial twist tasks were assessed using the lumbar and pelvic ranges of motion (ROMs) and coupled motion ratios (CMRs) as respectively the maximum flexion/rotation in the primary (i.e., intended) and the secondary (i.e., coupled) planes of trunk motion, where the latter was normalized to the conjugate ROM for better comparison.
The results showed age-related differences between the age groups above and under 50 years of age generally. A smaller LC during the forward bending and backward return tasks were observed in the older versus younger age groups, suggesting that the synergy between the active and passive lower back tissues is different between the older and younger people, which may affect the lower back mechanics. Also, smaller MARP and DP suggesting a more in-phase and more stable lumbopelvic rhythm were observed in the older versus younger age groups, which may be a neuromuscular strategy to protect the lower back tissues from excessive strain, in order to reduce the risk of injury. Furthermore, the coupled motion of lumbar spine in the transverse plane during the lateral bending to the left, and the coupled motion of pelvis in the sagittal plane during the axial twist to the right were larger in older versus younger age groups.
In summary, the lumbopelvic kinematics changes with aging, especially after the age of 50 which implies alterations in the active and passive tissue responses to the task demands, as well as the neuromuscular control patterns. Drawing a conclusion regarding ii the effect of aging on the risk of low back pain from these results requires a further detailed knowledge on age-related differences in spinal active and passive tissue properties.

Texto completoResumen
Aims: The aim of this study was to investigate Core Stability Exercise (CSE) induced changes in trunk sagittal acceleration as a measure of performance in participants following an acute onset of non-specific low back pain (LBP). Methodology: A Lumbar Motion Monitor (LMM) was used to measure trunk sagittal acceleration. The LMM was demonstrated to be reliable [Intra-Class Correlation (ICC) for average sagittal acceleration (0.96, 95% CI 0.90-0.98) and peak sagittal acceleration (0.89, 95% CI 0.75-0.96) with a 95% limit of agreement for the repeated measure of between -100.64 and +59.84 Deg/s2 ]. Pain was measured using the Visual Analogue Scale (VAS) and disability was measured with the Roland Morris Disability Questionnaire (RMDQ). Results: Differences in mean trunk sagittal acceleration between control and experimental groups at time points were assessed using a regression analysis (ratio of geometric means [95%CI]) and demonstrated to be not statistically significant (3 weeks (20%) 1.2 [0.9 to 1.6], p=0.2; 6 weeks (10%) 1.1 [0.8 to 1.5], p=0.7; 3 months (20%) 1.2 [0.8 to 1.9], p=0.9). Similarly, differences in mean pain score (3 weeks (30%) 1.3 [0.8-2.2], p= 0.3); 6 weeks (20%) 1.2 [0.7-2.0], p=0.6; 3 months (0%) 1.0 [0.5-1.9], p=1.0) and difference in mean disability score (6 weeks (0%) 1.0 [0.7-1.5], p= 1.0, 3 months (30%) 1.3 [0.8-1.9], p= 0.3) between groups were also not statistically significant. Conclusions: This work does not infer that CSE are definitively effective in reducing pain, improving subjective disability and improving trunk performance after an onset acute of non-specific LBP. However, there is a suggestion of clinical importance and a possible mechanism by which they may work. Further investigation into this mechanism may provide future effective management strategies for intervention of acute non-specific low back pain with optimistic cost implications for healthcare delivery in general and Physiotherapy in particular.

Texto completoResumen
A prerequisite for aeroelastic stability prediction inturbomachines is the understanding of the fluctuatingaerodynamic forces acting on the blades. Unsteady transonicflows are complex because of mutual interactions betweentravelling pressure waves, outlet disturbances, shock motion,and fluctuating turbulent boundary layers. Complex phenomenaappear in the shock/boundary layer region and produce phaselags and high time harmonics, which can give a significantcontribution to the overall unsteady lift and torque, andtherefore affect flutter boundaries, cause large localstresses, or even severely damage the turbomachine.
The present research work is concerned with theunderstanding of phenomena associated with travelling waves innon-uniform transonic flows and how they affect the unsteadypressure distribution on the surface as well as the far fieldradiated sound. In similitude with turbomachines potentialinteraction, the emphasis was put on the unsteady interactionof upstream propagating acoustic waves with an oscillatingshock in 2D and 3D nozzle flows. Both numerical andexperimental studies are carried out and compared with eachother.
Results shows that the unsteady pressure distribution, bothon the bump surface and within the channel, results from thesuperposition of upstream and downstream propagating waves. Itis believed that outlet pressure perturbations propagateupstream in the nozzle, interact in the high subsonic flowregion according to the acoustic blockage theory, and arepartly reflected or absorbed by the oscillating shock,depending on the frequency of the perturbations and theintensity of the SBLI. Furthermore the shock motion amplitudeis found to be related to the mean flow gradients and localwave length of the perturbations rather than to the shockboundary layer interaction. The phase angle between incomingpressure perturbations and the shock motion increases with theperturbation frequency but also depends on the intensity of theSBLI. Additionally the phase angle "shift" observed underneaththe shock location linearly increases with the perturbationfrequency and the shock strength. Such phase shift is criticalregarding aeroelastic stability and might have a significantimpact on the phase angle of the overall aerodynamic forceacting on the blade and shift the aerodynamic damping fromstable to exciting.

Texto completoResumen
The 1980s is a formative decade in American history. America sought to reestablish itself as a global power and to reassert the dominant ideology of white, patriarchal capitalism. Likewise, media producers in the 1980s sought to reassert the dominance of the white, male, muscled body in filmic representations. The identity politics of the 1980s and the depictions of the white, muscled body once prominent in the 1980s have been the site of conservative nostalgia for a young, male-dominated, cult audience that is a subset of a larger cultural trend known as retro film culture. This thesis provides historical context behind the populist 1980s B-action films from Cannon Group, Inc that celebrate violent masculinity in filmic representations with white, male action heroes. Equally important is the revival of VHS collecting and how this 1980s-inspired subculture reinforces white, patriarchal capitalism through the cult films they valorize and their capitalistic trading practices despite their claims of oppositionality against mainstream taste and Hollywood films. Lastly, this thesis reveals how a new cycle of contemporary films primarily produced outside of Hollywood reasserts and celebrates the dominance of the white, male, muscled body in filmic representations despite a postmodern and hyperconscious exterior. Overall, I argue how these areas of nostalgia are distinct, yet not unrelated, because they reassert white, patriarchal capitalism through the revival of conservative nostalgia for the 1980s.

Texto completoResumen
The purpose of this study was to examine the criterion-related validity of the sit and reach test as a measure of hamstring and low back flexibility in adult males and females. Subjects were 52 males and 52 females, 20 to 45 years of age. Hamstring flexibility was measured using a goniometer. Spinal flexibility was measured using a tape measure and an inclinometer. The sit and reach test was performed according to the AAHPERD Health Related Fitness Test Manual. Data were analyzed using correlations and appropriate descriptive statistics. Conclusions of the investigation were: 1) in adult males 20 to 45, the sit and reach test is a valid measure of hamstring flexibility but has questionable validity as a measure of low back flexibility, 2) in adult females 20 to 45, the sit and reach test is a moderately valid measure of hamstring flexibility and is not a valid measure of low back flexibility.

Lower Back Disorders account for 16-19% of work related claims and 33-41% of dollars paid in workers? compensation (as cited in Marras, 1999), with impacts to society approaching $100 billion dollars annually (as cited in Marras et al., 1999). Dr. William Marras engineered a device to track trunk kinematics in order to develop a Job Risk Classification Model for predicting high-risk group probability of lower back injury. The device has been validated, but other technologies such as 3-D motion capture can potentially gather the same data. This study examined the use of motion capture to apply two- and three-plane lifting tasks to the Marras model and compare results with commonly used assessment techniques. Regardless of the fact that the Marras model results were drastically different from NIOSH and RULA, motion capture was able to gather all necessary data for running the models and has a promising future in ergonomic assessments.

Texto completoResumen
Introduction: The biomechanical model of back pain has failed to find distinct relationships between intervertebral movement and pain due to limitations and variation in methods, and errors in measurement. Quantitative fluoroscopy (QF) reduces variation and error and measures dynamic intervertebral motion in vivo. This thesis used recumbent QF to examine continuous mid-lumbar intervertebral motion (L2 to L5) in patients with assumed mechanical chronic non-specific low back pain (CNSLBP) that had been clinically diagnosed. It aimed to develop kinematic parameters from the continuous data and determine whether these could detect subtle mechanical differences by comparing this to data obtained from healthy volunteers. Methods: This was a prospective cross sectional study. Forty patients with CNSLBP (age 21 to 51 years), and 40 healthy volunteers matched for gender, age and body mass index underwent passive recumbent QF in the coronal and sagittal planes. The patient group completed questionnaires for pain and disability. Four kinematic parameters were developed and compared for differences and diagnostic accuracy. Reference intervals were developed for three of the parameters and reproducibility of two were assessed. The radiation dose was compared to lumbar spine radiographs and diagnostic reference levels were established. Finally, relationships between patient’s pain and disability and one of the kinematic parameters (continuous proportional motion CPM) were explored. Results: Reproducibility was high. There were some differences in the coronal plane and flexion for each kinematic parameter, but no consistency across segments and none had high diagnostic accuracy. Radiation dose for QF is of the same magnitude as radiographs, and there were no associations between patient characteristics of pain and disability and CPM. Conclusion: Although the kinematic differences were weak, they indicate that biomechanics may be partly responsible for clinically diagnosed mechanical CNSLBP, but this is not detectable by any one kinematic parameter. It is likely that other factors such as loading, central sensitisation and motor control may also be responsible for back pain that is considered mechanical. QF is easily adapted to clinical practice and is recommended to replace functional radiography, but further work is needed to determine which kinematic parameters are clinically useful.

Su juosmeninės stuburo dalies skausmu, populiariai dar vadinamu juosmens skausmu, bent kartą per gyvenimą susiduria apie 80 proc. žmonių.

Medicininiu požiūriu didžiausia problema, susijusi su šia patologija, yra ta, kad itin komplikuotas juosmeninės stuburo dalies skausmo atsiradimo priežasties nustatymas (net 90 proc. atvejų ji yra nespecifinė, nenustatoma tiksli mechaninė disfunkcija, lemianti sutrikimą).

This pathology seriously complicates the quality of life: it is oftentimes accompanied by negative economic and social consequences (e.g. incapacity for work) as well as psychological consequences (e.g. depression). From medical point of view, the biggest problem associated with this pathology is that the diagnostics of the reason for emergence of low back pain is extremely complicated (in even 90% of the cases, this reason is non-specific, no accurate mechanical dysfunction is detected that would result in the disorder). This significantly aggravates the treatment and rehabilitation process. One of the most novel ways of diagnostics for the back pain worldwide is the establishment of indicators for hip rotation range of motion in the hip joint. So far, the views of scientists on this issue are rather controversial. Therefore, taking into account the relevance of the problem and its importance for the practice of a physicaltherapist, the objective was to adjust the hypothesis that a particular relation exists between the pain in the low back part of the spine and the hip rotation range of motion in the hip joint.

Texto completoResumen
Non-specific low back pain (LBP) is a major health problem affecting a substantial portion of the population. The current treatments offered for non-specific LBP are oftentimes unsuccessful because the acting mechanism(s) of most treatment options are unknown. Obtaining a better understanding about the acting mechanism behind existing treatment options is, therefore, essential for the improvement of non-specific LBP treatment and management. The objective of this study was to gain a more comprehensive understanding about the acting mechanism of high velocity low amplitude spinal manipulative therapy, specifically the impact that high velocity low amplitude spinal manipulative therapy may have on the active and passive spinal musculoskeletal stabilizing subsystems along with the resultant spinal stability for healthy participants. A pre-post intervention study design completed by six healthy participants was used to quantify changes in the above noted aspects of spinal stability using a series of tests performed both before and after six sessions of high velocity low amplitude spinal manipulative therapy. The tests included seated balancing tests, lower back range of motion tests, and stress relaxation test. The six sessions of high velocity low amplitude spinal manipulative therapy did not significantly affect any of the test measurements among our healthy participant group.

Texto completoResumen
Dans le sillage de la décolonisation, les récits colonialistes ont systématiquement été réécrits à partir de perspectives autochtones. Ce phénomène est appelé « The Empire writes back to the centre » - une tendance qui s'affirme dans la critique postcoloniale à la fin du XXe siècle. L'objectif de ces actes de réécriture est de lire des textes colonialistes d'une manière barthesienne à l'envers, de déconstruire les dogmes orientalistes et colonialistes, et éventuellement créer un dialogue où il était seulement un monologue. Tourner le texte colonial dedans/dehors et le relire à travers la lentille d'un code ultérieur permet le texte postcolonial de déverrouiller son précurseur colonial et le changer de l'intérieur. Dans ce cadre critique, Heart of Darkness (1899) de Joseph Conrad a été un texte particulièrement influent pour Chinua Achebe et V. S. Naipaul. Leurs romans Things Fall Apart (1958) et A Bend in the River (1979) peuvent être considérés comme une réécriture du roman de Conrad. Cependant, avant d'examiner leurs différentes stratégies de réécriture, il serait utile de les localiser dans la tradition postcoloniale de la réécriture. Alors que Achebe se démarque clairement comme la figure de proue du mouvement, le romancier trinidadien est difficile à catégoriser. Est-ce que Naipaul réécrit, de façon à critiquer, ou d'une manière d'adopter et de justifier, l’idéologie impériale? Comme pas toute réécriture est une forme de « writing back » en termes de critique anticoloniale, la position de Naipaul continue d'être considérée comme l’énigmatique entre-deux d'un «insider» devenu «outsider». Prenant acte de ses différentes perceptions critiques peut devenir un moyen de mettre en évidence de manière efficace la lecture erronée d’Achebe et le détournement de Naipaul du modèle Conradien, un moyen de fixer un cadre pour la conversation simulée cette thèse vise à créer entre les trois romanciersIn the wake of decolonization, colonialist narratives have systematically been rewritten from indigenous perspectives. This phenomenon is referred to as “the Empire writes back to the centre” – a trend that asserted itself in late twentieth-century postcolonial criticism. The aim of such acts of writing back is to read colonialist texts in a Barthesian way inside-out or à l’envers, to deconstruct the Orientalist and colonialist dogmas, and eventually create a dialogue where there was only a monologue. Turning the colonial text inside-out and rereading it through the lens of a later code allows the postcolonial text to unlock the closures of its colonial precursor and change it from the inside. Under this critical scholarship, Joseph Conrad’s Heart of Darkness (1899) has been a particularly influential text for Chinua Achebe and V. S. Naipaul. Their novels Things Fall Apart (1958) and A Bend in the River (1979) can be seen as a rewriting of Conrad’s novella. However, before examining their different rewriting strategies, it would be fruitful to locate them within the postcolonial tradition of rewriting. While Achebe clearly stands as the leading figure of the movement, the Trinidadian novelist is, in fact, difficult to pigeonhole. Does Naipaul write back to, that is criticize, or does he rewrite, and in a way adopt and justify, imperial ideology? Since not all rewriting involves writing back in terms of anti-colonial critique, Naipaul’s position continues to be explored as the enigmatic in-betweenness and double-edgedness of an “insider” turned “outsider.” Taking cognizance of these different critical perceptions can become a way to effectively highlight Achebe’s “(mis)-reading” and Naipaul’s “(mis)-appropriation” of Conrad, a way to set the framework for the simulated conversation this thesis seeks to create between the three novelists

En me déplaçant dans l'espace et en allant à la rencontre de l'inconnu, je commence à créer des espaces de réflexion. Le dos devient alors le sujet photographié et observé, ce point de départ de ma recherche théorique et esthétique, tout comme la base du rapport que j'établis avec le monde de l'art et les autres. En tant qu'interface, la vue de dos semble donner sur un lieu ou une territorialité anthropologique et artistique, qui suggère une autre manière d'être, de voir et de penser le mondeThrough the thesis Back view(s) : photography as identity and creation space, I question my photographic practice through the phenomenology of the gaze, while facing an obsession, the desire to see my own back and the back of the others. Starting from my own body as a source of experimentation, I express the need to exist in a different way through this part of my body that remains invisible to my own gaze. This search for recognition leads me towards developing artistic protocols, to face the other from the back. While I am traveling through space and meeting the unknown, I create different spaces of reflection. The back becomes the subject being photographed and observed, the starting point of my theoretical and aesthetic research, as well as the foundation that I build with the world of art and the others. As an interface, the view of the back seems to provide a look onto an anthropological and artistic place or territoriality, suggesting another way of being, seeing and thinking the world

Texto completoResumen
La lombalgie est un problème de santé public induisant de nombreuses répercussions sur le plan économique et social. Le passage à la chronicité concerne moins de 10% des lombalgies, mais représente 85% des coûts liés à la prise en charge de cette pathologie. Dans ce contexte, il parait indispensable de pouvoir optimiser les programmes de réentrainement à l’effort du lombalgique chronique afin de les rendre le plus efficace et le plus pertinent possible. Ce travail de thèse a pour objectif d’évaluer les facteurs mécaniques des membres inférieurs au moyen des relations moment-vitesse dans des conditions isocinétiques. Dans une première étude, nous avons évalué les muscles extenseurs du genou et les muscles fléchisseurs et extenseurs du tronc chez des sujets lombalgiques et des sujets sains. Nous avons, ainsi mis en évidence une faiblesse significative au niveau de la force et de la puissance des muscles extenseurs du genou chez les sujets lombalgiques associée à la faiblesse musculaire du tronc classiquement évoquée pour cette population. Après avoir mis en place, dans une seconde étude, un protocole d’évaluation permettant d’établir des relations moment- et puissance-vitesse pour les muscles extenseurs et fléchisseurs de la hanche, nous avons évalué la force et la puissance de ces groupes musculaires chez des sujets lombalgiques. Les résultats ont, comme pour la première étude, mis en avant une faiblesse significative au niveau de la force et de la puissance de ces groupes musculaires, par rapport à des sujets sains, avec un déficit plus marqué au niveau des extenseurs, comme pour le tronc. L’ensemble des résultats obtenus dans le cadre de ce travail de thèse démontre qu’il est important de proposer un travail de force et de puissance au niveau des membres inférieurs pour les patients lombalgiques chroniques afin de mieux lutter contre le syndrome de déconditionnement qui touche l’ensemble des chaines musculaires des patientsLow back pain is a public health problem inducing economical and social consequences. Chronicity involves less than 10% of low back pain, but represents 85% of the total costs related to this pathology. In this context, it seems essential to optimize chronic low back pain rehabilitation programs to make them more effective and relevant. The purpose of this phD was then to evaluate lower limbs mechanical factors using torque- and power-velocity relationships. In a first study, knee extensors muscles and trunk flexor and extensor muscles were evaluated in chronic low back pain and healthy subjects. A significant knee extensor strength and power weakness weas observed for chronic low back pain subjects, associated with the typical trunk weakness referred to this population. The second study focused on establishing a protocol allowing assessing hip flexor and extensor torque- and power-velocity relationships. This protocol was then applied to evaluate flexor and extensor hip muscles in chronic low back pain subjects. Results, in accordance with the first study, highlighted a significant strength and power weakness for hip muscle groups in chronic low back pain relative to healthy subjects, with a greater hip extensor deficit, as it is generally observed for the trunk.In conclusion, these different studies showed the importance of proposing torque and power lower limbs rehabilitation for chronic low back pain patients to better fight against the deconditioning syndrome that affects all muscular chains in this population

Texto completoResumen
Cette thèse traite de l'intégration du trafic multimédia sur la voie montante de l'interface radio de l'UMTS. Le problème est abordé dans sa globalité, considérant à la fois les possibilités de partage de la ressource, une bonne caractérisation du trafic à transmettre et les possibilités ouvertes dans la norme UMTS. L'attention est plus particulièrement portée sur la vidéo MPEG4 et les données de type Internet. La première partie de la thèse dégage une approche du partage de ressource radio en mode WCDMA. Les performances du mécanisme de multiplexage de niveau couche physique avec qualité de transmission différenciée et l'impact du mécanisme d'adaptation de débit sont évalués. Cette analyse débouche sur la construction d'une fonction de coût pour l'estimation de la capacité cellulaire multiservice et la proposition d'une méthode d'équilibrage adaptatif de la qualité de transmission. La seconde partie de la thèse présente un nouveau modèle statistique pour le trafic vidéo MPEG4. Ce modèle consiste en une particularisation du processus DBMAP et permet d'évaluer analytiquement les performances de transmission à la traversée d'un système à file d'attente. La dernière partie de la thèse intègre l'ensemble de ces travaux pour aboutir à une stratégie d'ordonnancement coopérative multiplexant efficacement les paquets issus d'applications multimédia temps réel et non temps réel, dans le respect des contraintes d'intégrité et de retard. Une méthode analytique faisant appel à la théorie des files d'attente de type M/G/1 est fournie pour le calcul des retards subis par les paquets vidéo MPEG4 et les données lorsque cette stratégie est mise en œuvre au sein d'un réseau UMTSThis thesis deals with the integration of multimedia traffic on the uplink of the UMTS radio interface. The problem is tackled in its globality, considering jointly the resource sharing possibilities, a good characterization of the traffic to transmit and the possibilities opened in the UMTS standard. The attention is more particularly focused on MPEG4 video and data of the Internet type. The first part of the thesis provides an approach of radio resource sharing in WCDMA mode. The performances of the physical layer multiplexing mechanism with quality of transmission differentiation and the impact of the rate matching mechanism are evaluated. This analysis serves as a basis for the construction of a cost function for estimating the multiservice cellular capacity and the proposition of a quality of transmission adaptive balancing method. The second part of the thesis presents a new statistical model for MPEG4 video traffic. This model consists in a customization of the DBMAP process and allows evaluating the queueing performances analytically. The last part of the thesis integrates this set of works yielding a cooperative scheduling strategy that efficiently multiplexes the packets generated by real time and non real time multimedia applications while respecting the integrity and delay constraints. An analytical method based on M/G/1 type queueing systems theory is given for computing the delays incurred by MPEG4 video and data packets when this strategy is implemented in a UMTS network

Cho, Seong-Woong. "La chambre de la "mère morte : Etude sur la solitude et la mort". Thesis, Grenoble, 2012. http://www.theses.fr/2012GRENL030.
Texto completoResumen
L'initiation d'Henri Beyle à la solitude et à la mort se passe essentiellement dans la chambre de la « mère morte, » dans une intimité à la tonalité érotique. La présente étude a le projet d’analyser l'univers de la représentation inconsciente de Stendhal à partir d'un thème unique : celui de la chambre de la « mère morte », remplie du sentiment de la solitude et de la mort. La spécificité de son expérience de la chambre poursuit Henri Beyle la vie durant, et se reflète dans son univers romanesque. Les images poétiques, résultant des situations symboliques de la chambre, de la solitude et de la mort, sont nombreuses et expriment un processus inconscient de l'écriture stendhalienne. Que l'on fasse de la mort un accomplissement de la solitude, de la solitude une approche de la mort, la mort est envisagée par Stendhal comme un retour. La chambre est à la fois le point de départ et le point d'arrivée. Dans le monde imaginaire recherché par les héros stendhaliens se trouve toujours la chambre de la « mère morte ». L'art devient un moyen de surmonter le complexe de la mort. C'est dans l'écriture romanesque qu'Henri Beyle retrouve la place vide de sa mère et une chambre à soiA seven-year-old child, not yet mature enough to comprehend the meaning of death, cannot mourn the loss of his mother, is cruelly punished by his aunt. That boy is Stendhal. Henri Beyle's realization of the images of solitude and death is mainly portrayed in his dead mother's bedroom, which has an erotic and incestuous atmosphere. This study explains the universe of Stendhal's unconscious representation, beginning with this unique theme: his dead mother's room which is filled with the feeling of solitude and death. The specific experience of the room continues to obsess Henri Beyle throughout his life, and his literary works are impelled by the memories or the images of his mother. The poetic images, resulting from the symbolic situation of the room, and obviously solitude and death, are numerous, and express an unconscious process of Stendhal's writing. Whether we consider death as a circumambulation around the theme of solitude, or whether we consider death as what lies inside solitude, death is regarded by Stendhal as a way to get back to his mother. His dead mother's room is both the starting and the ending point. At the heart of the imaginary work sought by Stendhal's protagonists, mother's room is easily found. Art then becomes a way to overcome the obsession with death. It's in the romantic writing that Stendhal found the empty space left by his mother, and his own room. This is the originality of Stendhal's piece

In this thesis, a batch self-learning method is proposed to automatically determine a motion fuzzy controller so that the motion of the controlled wheeled robot has a good performance. This method in each generation can be separated into three states: a control state, a controlled plant identification state, and a controller learning state. There are two fuzzy systems in this method. One is a fuzzy identifier to identify the real wheeled robot and the other is a fuzzy controller to control the wheeled robot. In the first state of control state, the motion fuzzy controller will control the real wheeled robot and the input and output data of the robot is collected, where the motion characters of the robot on the plane are included. In the second state of the controlled plant identification state, based on the obtained input and output data in the first state, a fuzzy identifier with a good approximation performance is obtained by Genetic Algorithm. In the third state of controller learning state, the fuzzy identifier obtained in the second state is viewed as the controlled plant and a fuzzy controller with a good control performance is obtained by Genetic Algorithm. These three states of the learning method will be repeated until the maximum generation is reached. The antecedent and consequent parameters of the fuzzy system are viewed as a parameter set and Genetic Algorithm is proposed to choose appropriate parameter sets so that the selected fuzzy identifier has a good approximation and the selected fuzzy controller has a good control performance. The parameters of fuzzy controller can be automatically selected by the batch self-learning method so that the obtained motion fuzzy controller has a good control performance. Moreover, different robots in different environment using the proposed method also can let the obtained controller have a good control performance. Therefore, the proposed self-learning method has a good adaptability. Some simulation results in FIRA 3D robot soccer simulator are presented to illustrate that the controller can control the robot to the destination smoothly.

Prior research pays attention to several topics concerning earing management. This study works on two issues related to firm''s cookie-jar and big-bath manipulations: (1) factors that drive firms to take these two actions, and (2) how their stock prices perform after the manipulation. We consider three dimensions of factors that can drive firms’ cookie-jar and big-bath manipulations. We find that firms tend to take a big-bath when their company locations are in the disaster area. We also find that firms have strong stock performance after natural disaster than matching samples.

In this thesis, the back-propagation neural network system is implemented for on-line learning of the ankle joint of the biped robot walking forward. The system acquires the inclining angles of the center of gravity by the inclination sensor and the joint angles by the AI servo motors when the manual teaching is applied for the on-line learning templates of the biped robot walking motions. Regarding the method and process of research, the manual teaching is approached to the motion trajectory of a biped robot, and then all rotating angles of robot joints and the inclining information of the center of gravity are detected via the sensors to be saved. Repeat the original operation route and reconfirm whether the motion trajectory is taught to fall within the center of gravity for regarding as training sample parameters for the motion trajectory. Thus, the motion trajectories of the hip joint angle, the knee joint angle, and the inclining angles of the center of gravity are conducted to approach the ankle joint through the training of the back-propagation neural network system to assure the center of gravity located inside of range of the soles of the feet. The experimental results are shown that the biped min-robot can automatically adjusted the center of body gravity during the walking motion through the back-propagation neural network system.

Texto completoResumen
Introduction
Various authors have proposed that there may be altered hip rotation range of
motion (ROM) in patients with low back pain (LBP). However, limited studies have
been conducted to investigate the association between hip rotation ROM and LBP
specifically in distance runners. The aim of this study was to determine whether
there is an association between hip rotation ROM and non-specific LBP in
distance runners.
Methods
A cross-sectional design was used to look at the relationship between hip rotation
ROM and LBP. Thirty five runners with LBP (24 males, 11 females) and 51
runners without LBP (29 males, 22 females) participated in the study. A
questionnaire was used to divide participants into LBP and no LBP groups and to
evaluate certain factors specific to LBP. Passive rotation ROM was measured in
prone position using a hand-held inclinometer.
Results
Results showed no statistically significant difference (p>0.05) in hip rotation ROM
between the two groups. Furthermore, no statistically significant difference
(p>0.05) was found for factors specific to running, between the two groups. Conclusion
Although no association was found between hip rotation ROM and LBP in distance
runners, further research is needed into other possible causative factors of LBP in
distance runners.
Keywords
Low back pain, hip biomechanics, hip mobility, hip rotation, sports and running
Operational definitions
Low back pain (LBP): pain and discomfort located below the costal margins
and above the gluteal folds, with or without associated leg pain (Van Tulder et
al 2006).
Non-specific LBP: pain not attributable to a clearly recognisable pathology
(Koes et al 2006).
Healthy distance runner: a runner who has had no LBP symptoms within
the last 6 months.
Time trial: an unofficial road running race in which participants are timed
individually over a set distance, in this case, 4km.

This thesis undertakes a study of four films, directed by Arab directors from Palestine, Lebanon, America and the United Arab Emirates, and argues that these works speak back to the negative representation of Arabs in mainstream Hollywood films. It examines the methods these directors have deployed to contribute to a consciousness on a cultural level. These include the films Amreeka (dir. Dabis, 2009: USA, National Geographic Entertainment), Paradise Now (dir. Abu-Assad, 2005: USA, Warner Bros), West Beirut (dir. Doueiri, 1998: Belgium, France, Norway, Lebanon: 38 Production) and City of Life (dir. Mostafa, 2009: UAE: Filmworks). I argue that these films speak back to the representation of Arabs created by Hollywood. In all the films I analyse the representation of the characters, which allows viewers into their frames of reference and makes them relatable. The characters are ordinary people facing the situations of everyday life in various settings. Whether it is the limitation of their geographical location while living under occupation in Palestine as in Amreeka and Paradise Now, emigrating to America and coping with xenophobia as in Amreeka, living in a country exploding as civil war breaks out as in West Beirut, or adjusting to multiculturalism as in City of Life, filmmakers are allowing viewers into the lives of Arabs, representing them in terms of all their successes, failures, vulnerabilities and excesses. They are human beings with the same concerns as all humanity, for peace in their countries, the stability of their societies and the safety of their families. My investigation analyses the films through the theoretical lenses of Stuart Hall’s theory of representation (2012), Edward Said's Orientalism (1997), and decoloniality as advocated by Maldonado-Torres (2014) and Mignolo (2011). A postmodern reading of City of Life is made within Baudrillard's theory of hyperreality (2010), Lyotard’s concept of the grand narrative (1986) and Žižek’s concept of the dematerialisation of real life. A close reading of the films, using the research methods of semiotics and narratology, enables a deconstruction of some obscure elements, such as the embedded meaning in dialogue or the messages implicit in the mise en scène. In the process, cultural contradictions and similarities are explored and uncovered.English Studies

This research is based on particle swarm algorithm combined with back-propagation neural network to improve the optimization of robot AI motor and the training strategy of the biped robot. The system is applied with AI motor feedback signals to compute the transfer function of the AI motor, and then through the manual mode to teach the motion trajectory for the motion control parameters of the biped robot . The system is implemented by Visual Basic and Matlab as a tool for program developments. In the research method and procedure, the PD parameters of AI motors are first optimized by the particle swarm algorithm, and then the biped robot motion trajectories are trained by manual mode. The feedback signals of all angle information are recorded as the input foot information of the hip and knee angle. Afterward, the system used the back-propagation neural network training to approach the output value as the ankle angle for the assurance the center of robot gravity located within two soles of the feet. The experimental results are shown that the particle swarm algorithm is optimized the PD parameters of AI motors as well as of the back-propagation neural network training through input angles automatically approach the corresponding ankle angles so that the motion stability of the biped is ensured. Importantly, the system is successfully applied to the robot motion learning of the upstairs walking motion.

In this paper, we propose an adaptive image enlargement scheme based on iterative back-projection. Initial estimates of each enlarged image can be individually created from the spatial and temporal domains by using sub-pixel interpolation and sub-pixel motion estimation. Then, based on the initial estimates and image content, reconstructed images are derived by using a modified iterative back-projection technique and fused into a enlarged image. Finally, a low-pass filter as a post-processing is applied to reduce the blocking artifacts in the reconstructed high-resolution images. Our experiment results demonstrate that, in terms of PSNR and NQM, the proposed scheme is superior to existing methods.
