Persian Orthography : Modification or Changeover? (1850-2000)

Hashabeiky, Forogh January 2005 (has links)
The present study provides a description of the standardization process of Persian orthography since the introduction of the Arabic alphabet, with a focus on this process in modern times (1850-2000). Using theories related to orthography standardization as its background, this work seeks an explanation for the prolonged standardization process of Persian orthography, and presents the frameworks within which this standardization has been carried out. The most recent state of Persian orthography is presented through an investigation of the current attitudes towards the problems of Persian orthography and possible frameworks for a potential reform, as well as through an investigation of the current tendencies in the manner of presenting different orthographic parameters within Persian contemporary texts. How and by whom the orthography of today’s Persian texts is governed is another aspect to be examined here. The most important conclusion to be drawn from the present study is that there is a strong tendency towards approving reform proposals that can be integrated with the present orthography, and maintain the present appearance of Persian orthography as much as possible. One of the main reasons behind this tendency is the concern of an interruption in cultural continuity in the event of an alphabet reform or any other drastic change in the present appearance of the orthography. This concern takes into account the political, social, cultural, structural, and economic conditions in Iran, as well as the complexity of language planning projects.

Avancements dans l'estimation de pose et la reconstruction 3D de scènes à 2 et 3 vues / Advances on Pose Estimation and 3D Resconstruction of 2 and 3-View Scenes

Fernandez Julia, Laura 13 December 2018 (has links)
L'étude des caméras et des images a été un sujet prédominant depuis le début de la vision par ordinateur, l'un des principaux axes étant l'estimation de la pose et la reconstruction 3D. Le but de cette thèse est d'aborder et d'étudier certains problèmes et méthodes spécifiques du pipeline de la structure-from-motion afin d'améliorer la précision, de réaliser de vastes études pour comprendre les avantages et les inconvénients des modèles existants et de créer des outils mis à la disposition du public. Plus spécifiquement, nous concentrons notre attention sur les pairs stéréoscopiques et les triplets d'images et nous explorons certaines des méthodes et modèles capables de fournir une estimation de la pose et une reconstruction 3D de la scène.Tout d'abord, nous abordons la tâche d'estimation de la profondeur pour les pairs stéréoscopiques à l'aide de la correspondance de blocs. Cette approche suppose implicitement que tous les pixels du patch ont la même profondeur, ce qui produit l'artefact commun dénommé "foreground-fattening effect". Afin de trouver un support plus approprié, Yoon et Kweon ont introduit l'utilisation de poids basés sur la similarité des couleurs et la distance spatiale, analogues à ceux utilisés dans le filtre bilatéral. Nous présentons la théorie de cette méthode et l'implémentation que nous avons développée avec quelques améliorations. Nous discutons de quelques variantes de la méthode et analysons ses paramètres et ses performances.Deuxièmement, nous considérons l'ajout d'une troisième vue et étudions le tenseur trifocal, qui décrit les contraintes géométriques reliant les trois vues. Nous explorons les avantages offerts par cet opérateur dans la tâche d'estimation de pose d'un triplet de caméras par opposition au calcul des poses relatives paire par paire en utilisant la matrice fondamentale. De plus, nous présentons une étude et l’implémentation de plusieurs paramétrisations du tenseur. Nous montrons que l'amélioration initiale de la précision du tenseur trifocal n'est pas suffisante pour avoir un impact remarquable sur l'estimation de la pose après ajustement de faisceau et que l'utilisation de la matrice fondamentale avec des triplets d'image reste pertinente.Enfin, nous proposons d'utiliser un modèle de projection différent de celui de la caméra à sténopé pour l'estimation de la pose des caméras en perspective. Nous présentons une méthode basée sur la factorisation matricielle due à Tomasi et Kanade qui repose sur la projection orthographique. Cette méthode peut être utilisée dans des configurations où d'autres méthodes échouent, en particulier lorsque l'on utilise des caméras avec des objectifs à longue distance focale. La performance de notre implémentation de cette méthode est comparée à celle des méthodes basées sur la perspective, nous considérons que l'exactitude obtenue et la robustesse démontré en font un élément à considérer dans toute procédure de la SfM / The study of cameras and images has been a prominent subject since the beginning of computer vision, one of the main focus being the pose estimation and 3D reconstruction. The goal of this thesis is to tackle and study some specific problems and methods of the structure-from-motion pipeline in order to provide improvements in accuracy, broad studies to comprehend the advantages and disadvantages of the state-of-the-art models and useful implementations made available to the public. More specifically, we center our attention to stereo pairs and triplets of images and discuss some of the methods and models able to provide pose estimation and 3D reconstruction of the scene.First, we address the depth estimation task for stereo pairs using block-matching. This approach implicitly assumes that all pixels in the patch have the same depth producing the common artifact known as the ``foreground fattening effect''. In order to find a more appropriate support, Yoon and Kweon introduced the use of weights based on color similarity and spatial distance, analogous to those used in the bilateral filter. We present the theory of this method and the implementation we have developed with some improvements. We discuss some variants of the method and analyze its parameters and performance.Secondly, we consider the addition of a third view and study the trifocal tensor, which describes the geometric constraints linking the three views. We explore the advantages offered by this operator in the pose estimation task of a triplet of cameras as opposed to computing the relative poses pair by pair using the fundamental matrix. In addition, we present a study and implementation of several parameterizations of the tensor. We show that the initial improvement in accuracy of the trifocal tensor is not enough to have a remarkable impact on the pose estimation after bundle adjustment and that using the fundamental matrix with image triplets remains relevant.Finally, we propose using a different projection model than the pinhole camera for the pose estimation of perspective cameras. We present a method based on the matrix factorization due to Tomasi and Kanade that relies on the orthographic projection. This method can be used in configurations where other methods fail, in particular, when using cameras with long focal length lenses. The performance of our implementation of this method is compared to that given by the perspective-based methods, we consider that the accuracy achieved and its robustness make it worth considering in any SfM procedure

Développement de la compétence orthographique : étude des connaissances des frontières lexicales d'élèves sans difficulté à l'écrit et d'élèves dyslexiques du primaire / Development of spelling ability : study of lexical boundary knowledge of normally-developing students and primary school students with dyslexia

Costerg, Agnès 19 June 2018 (has links)
La lecture et l’écriture sont deux activités complexes qui contribuent à la réussite dans toutes les disciplines scolaires. Pour l’apprenti scripteur, et plus particulièrement pour l’élève qui éprouve des difficultés d’apprentissage (notamment l’élève dyslexique), l’apprentissage de l’orthographe représente un réel défi et nécessite souvent des années d’effort. Or, la connaissance du code orthographique constitue le socle sur lequel se construit la compétence orthographique. La reconnaissance et la production de mots écrits impliquent la mise en place d’un noyau de connaissances communes se rapportant aux connaissances orthographiques, c’est-à-dire aux connaissances rattachées aux propriétés phonologiques, morphologiques et visuelles du code orthographique. Ainsi, tout au long du développement de la compétence orthographique, le lecteur-scripteur doit notamment construire des représentations orthographiques de plus en plus stables et mieux définies qui tiennent compte de l’ensemble des propriétés du code orthographique. Des données empiriques récentes indiquent toutefois que les élèves dyslexiques, qui commettent davantage d’erreurs orthographiques de fusion et de segmentation de mots que les élèves sans difficulté à l’écrit, ne semblent pas disposer de représentations orthographiques précises des mots à orthographier, et plus spécifiquement de bonnes représentations du début et de la fin des mots. L’objectif général de cette étude est donc d’expliquer les erreurs orthographiques de frontières lexicales chez les élèves dyslexiques. Comme à notre connaissance, il n’existe pas de norme quant au développement des connaissances des frontières lexicales chez les élèves normo-lecteurs/scripteurs, le premier objectif spécifique est de décrire, de façon transversale et longitudinale, les performances d’élèves normo-lecteurs/scripteurs de la maternelle à la 4e année du primaire à des épreuves évaluant les connaissances des frontières lexicales (étude 1). La mise en place de cette référence développementale a permis de répondre au deuxième objectif spécifique qui est d’évaluer les connaissances des frontières lexicales d’élèves dyslexiques du primaire (étude 2). Pour évaluer les compétences en lecture et en production de mots, une épreuve de lecture de la batterie de tests du K-ABC et une dictée de mots insérés en contexte phrastique ont été proposées. Trois épreuves (décision lexicale, identification lexicale et permutation lexicale), variant en termes de degré de contraintes cognitives, ont été effectuées par tous les participants à l’oral et à l’écrit afin d’évaluer leurs connaissances des frontières lexicales. / Reading and writing are two complex activities that contribute to success in all school subjects. For apprentice writers, and particularly for students with learning difficulties (notably students with dyslexia), learning to spell represents a real challenge and often requires years of effort. To be successful, students require knowledge of the orthographic code, which is the foundation upon which spelling ability it built. To recognize and produce written words, students must develop a set of core skills that are linked to orthographic knowledge, including knowledge of the phonological, morphological and visual properties of the orthographic code. As their spelling skills develop, readers and writers must construct increasingly stable and better defined orthographic representations that reflect the properties of the orthographic code. However, recent empirical research has found that students with dyslexia, who tend to make more errors related to word merging and segmentation than students without writing difficulties, do not seem to have accurate orthographic representations of the words they are trying to spell, particularly of the beginnings and endings of words. Therefore, the general aim of this study is to explain spelling errors occurring at word boundaries in dyslexic children. To our knowledge, no typical trajectory of development has been established for normally-developing readers/writers with regards to knowledge of lexical boundaries. Therefore, using both cross-sectional and longitudinal analyses, this study’s first objective is to describe the performances of normally-developing reader and writers from kindergarten to grade 4 on tasks related to lexical boundary knowledge (Study 1). With this developmental reference having been established, the second study will evaluate lexical boundary knowledge in primary school students with dyslexia (study 2). To evaluate ability in reading and word production, a reading test from the K-ABC battery and a dictation task requiring students to insert words in the context of a sentence were administered. To evaluate knowledge of lexical boundaries, three tasks (a lexical decision task, a lexical identification task, and a lexical permutation task) were completed by all participants in oral and written form, each of which varied according to the level of cognitive constraint involved in completing the task.

Processus visuo-attentionnels et perceptifs dans la mise en place du codage orthographique / Visuo-attentional and perceptual processes in orthographic coding

Leibnitz, Laurie 12 December 2016 (has links)
Identifier le plus complètement possible les processus impliqués dans le développement de la lecture est nécessaire afin de permettre à un maximum d’enfants d’accéder à la maîtrise de la langue écrite. Si l’importance des compétences linguistiques (e.g., conscience phonologique) a été largement démontrée, peu d’études en revanche se sont spécifiquement intéressées au rôle des processus visuo-attentionnels et perceptifs dans l’apprentissage de la lecture ou à leur implication dans certains dysfonctionnements langagiers. Dans ce cadre, nous avons réalisé trois études longitudinales afin d'interroger le rôle des processus visuo-attentionnels et perceptifs, spécifiques au codage orthographique, dans l'apprentissage de la lecture. Le premier objectif de cette thèse était d'étudier si ces processus constituaient des pré-requis à l'apprentissage de la lecture. Nous avons administré à 89 enfants entre la MSM et le CP, une tâche d'identification de cible en fovéa (étude 1) et en parafovéa (étude 2). Nous avons observé que la précocité de la mise en place du codage orthographique prédisait le niveau de lecture au CP. Le second objectif était de dépister en maternelle, les enfants susceptibles de présenter des difficultés en lecture. Dans cette optique, les capacités visuo-attentionnelles et perceptives ont été évaluées auprès de 78 enfants entre la GSM et le CP, au moyen du logiciel VISA-kids que nous avons développé. Le traitement local prédisait les compétences en lecture au CP. Notre travail a ainsi mis en évidence l'importance des capacités visuo-attentionnelles et perceptives, à la fois pour l'apprentissage de la lecture et la prévention des difficultés en lecture. / Identifying the processes involved in the development of reading is necessary to enable as many children as possible to become skilled processors of written language. Although the importance of spoken language skills (e.g., phonological awareness) has been widely demonstrated, few studies, however, have specifically investigated the role of visuo-attentional and perceptual processes in learning to read, or their possible involvement in reading disorders. In this context, we completed three longitudinal studies to examine the role of visuo-attentional and perceptual processes involved in orthographic coding during the first steps of learning to read. The first goal of this thesis was to investigate whether these processes were prerequisites for learning to read. We administered to 89 preschool children and first graders, a target identification task in the fovea (study 1) and the parafovea (study 2). We observed that the precocity of establishment of efficient orthographic coding predicted reading level in first grade. The second objective aimed at improving screening for future reading difficulties in kindergarten children. We developed software (VISA-kids) for assessing visuo-attentional and perceptual abilities that we evaluated in 78 preschool and first grade children. Local processing predicted reading level in the first grade. Our work has highlighted the importance of visuo-attentional and perceptual processes for learning to read and the importance of considering these factors for the prevention of reading difficulties.

O Dicionário para escolas primárias de Ludwig Wittgenstein e a virada linguística / Ludwig Wittgensteins dictionary for primary school and the linguistic turn

Reis, Maria Fernanda de Moura 03 May 2010 (has links)
Esta pesquisa trata de questões de natureza teórica e tem como objetivo conhecer o trabalho do filósofo Ludwig Wittgenstein (1889-1951), como professor primário, realizado de 1920 a 1926 junto a crianças em idade de alfabetização. Esta atividade no magistério ocorreu em escolas primárias da zona rural austríaca e resultou na publicação, em 1926, da obra Dicionário para Escolas Primárias (Wörterbuch für Volksschulen). Nossa hipótese, ao longo desta investigação, é de que este período como docente de crianças contribuiu significativamente para a mudança do pensamento de Wittgenstein, colocando em questão as afirmativas referentes às relações entre linguagem, pensamento, mundo e a forma lógica existentes no Tractatus, sua grande primeira obra filosófica, o que levou o filósofo a formular posteriormente as noções de uso e formas de vida, presentes nas obras da segunda fase do seu pensamento. Consideramos pertinente levantar aspectos históricos da vida do filósofo e compreender o que o levou a atividade do ensino escolar. Além disso, buscamos compreender as diretrizes da Reforma Escolar austríaca dirigida por Otto Glöckel, movimento de transformação escolar no qual Wittgenstein esteve envolvido e que julgamos ter influenciado sua antiga forma de pensar. / This research analyses theoretical matters and aims at understanding the work of the philosopher Ludwig Wittgenstein (1889-1951), as a primary education teacher, developed between 1920-1926 with children who were being alphabetized. This educational work was developed in primary schools in the Austrian countryside. As a result of the experience Dictionary for Primary School (Wörterbuch für Volksschulen) was published in 1926. Our hypothesis in this research is that the period Wittgenstein worked as a primary teacher contributed, to a large extend, to a change in his beliefs, putting into question the statements concerning the relationship between language, thought and the world; as well as the logic form present in the Tractatus, his first great philosophical work. Later on, this experience lead the philosopher to formulate the notions about the use and forms of life, present in the works of the second period of his thought. We considered it was pertinent to discuss historical facts about the philosophers life and understand the circumstances that lead him to work in the primary education. Besides that, we aimed at understanding the guidelines of the Austrian School Reform under Otto Glöckel, a school transformation process in which Wittgenstein was involved and that we believe to have influenced his previous thought.

Then gaps are left after all the systematic work of phoneme-grapheme relationship is becoming less effective.It is clear, now, that many students arrive at the final years of elementary school with many difficulties in writing, presenting several spelling deviations, including the exchange between graphemes representing phonemes that are distinguished by sonority. Which makes them unable to make competent use of writing, including in their social practices.Thus, the present study of educational intervention, interpretative, aimed to develop educational activities for five students of 8th grade of elementary school, to encourage reflection on the fonograf?micas relations. After conducting a diagnostic assessment, elaborated a set of activities that were divided into three blocks: Conceptualizing, exercising and evaluating. Through questions, the student is taken to watch six pairs of words and the to perceive that the distinction between them is in the vibration or not of the vocal folds.The research was applied to five students in a class of 8th grade of elementary school in a public school, located in the municipality in the state of Rio de Janeiro, in which the teacher-researcher is a professor ruler of Portuguese Language and Writing. The analysis of the responses found that students have significant gaps in the development of phonological awareness and therefore difficult to represent spelled certain words.It is proposed as a possible solution to the identified difficulties, the development work of phonological awareness start from kindergarten to both, it is known that education professionals need to know how to do this.In addition, research is needed to pursue strategic effective for the development of phonological awareness of students who no longer are in the literacy phase. / O trabalho de desenvolvimento da Consci?ncia Fonol?gica vem sendo negligenciado.

Esse fatodificulta o uso competente da escrita, inclusive em suas pr?ticas sociais.Sendo assim, a presente pesquisa de interven??o educacional, de cunho interpretativo, teve como objetivo elaborar atividades did?ticas para cinco alunos de 8? ano do Ensino Fundamental, que privilegiam a reflex?o sobre as rela??es fonograf?micas. Ap?s a realiza??o de uma avalia??o diagn?stica, elaborou-se um conjunto de atividades que foram divididas em tr?s blocos, a saber: (i) conceituando; (ii)exercitando; e (iii)avaliando. Por meio das quest?es, os alunos foram levados a observar seis pares de palavrase a perceber que a distin??o entre eles est? na vibra??o ou n?o das pregas vocais.A pesquisa foi aplicada para cinco alunos de uma turma de 8? ano do Ensino Fundamental de uma escola p?blica, localizada em munic?pio do interior do Estado do Rio de Janeiro, na qual a professora-pesquisadora ? professora regente de L?ngua Portuguesa e Reda??o. A an?lise das respostas dadas constatou que os alunos t?m hiatos relevantes no desenvolvimento da consci?ncia fonol?gica e, consequentemente, dificuldades para representar ortograficamente determinadas palavras.

Läsflyt : En interventionsstudie på två läsmetoders effekter på läsförmågan. / Reading fluency :  An intervention study on reading skills

Ljunggren, Marianne January 2010 (has links)
Sammanfattning   Syfte: Att undersöka två läsmetoders effekter på tolv elever från skolår 2, 3 och 4 avseende fonologisk och ortografisk läsförmåga, läsflyt, läsförståelse och RAN (Rapid Automatic Naming) samt jämföra resultaten med en grupp elever som fått traditionell specialundervisning under samma tid.   Metod: 52 elever genomförde en screening med avseende att mäta läsflyt och läsförståelse. Av dessa valdes 12 elever ut som hade svårigheter i läsflyt och korrekt läsning, fyra elever från varje skolår, 5 pojkar och 7 flickor. Eleverna delades i två lika stora grupper som tränade ordavkodning med två olika metoder i en-en-undervisning, 20 minuter tre gånger per vecka i sex veckor. De 18 eleverna fick utföra ytterligare fem läs- och skrivtest före och efter interventionen.   Resultat: De båda interventionsgrupperna förbättrade sina resultat på flera test mer än gruppen som fick traditionell specialundervisning. Elever som tränat Rydaholmsmetoden fick bättre resultat i alla högläsningstest utom ett. Elever som tränat datorprogrammet Hitta ord fick bättre resultat i nonsensordtestet samt de båda tystläsningstesten.   Diskussion: Resultatet skulle kunna tydas så att Rydaholmsmetoden tränar artikulation, ordmobilisering och läsflyt i högläsning medan datorprogrammet Hitta Ord tränar den ortografiska och fonologiska läsningen mer. Vidare skulle studiens resultat kunna tolkas så att en-en-undervisning är effektivare än traditionell specialundervisning. / Abstract Aim: To investigate two reading methods effect on twelve students from school year 2, 3 and 4 in phonologic and orthographic reading, reading fluency and RAN comparing to traditional special education.   Method: 52 students were tested in reading fluency. Twelve students with reading problems were elected, four students from each class, 5 boys and 7 girls. They were divided in two groups and had an intervention in two different word reading program in a one-to-one-torturing for 20 minutes three times a week in six weeks. A group of six students, were chosen as a comparing group. All 18 students were testing the same battery of tests before and after the six weeks.   Result: The result showed that both intervention groups were improved their result more than the group trained with traditional special education. Rydaholms method group improved more in all loud reading tests except Nonsen word reading test while the computer trained group improved more in both cilent reading test and made a small improve in Nonsen word reading test.   Discussion: The result could interpret that Rydaholm method trained articulation, word mobilization and loud reading fluency more while the computer based program trained orthographic and phonological reading more. The result could also interpret that one-to-one-torturing improve reading ability more than traditional special education in this reading abilities.

Datorträning i läsflyt och stavning : analys och utvärdering av fixerad och resultatstyrd flash-cardexponering

Johansson, Maj-Gun January 2010 (has links)
During the last decade new attention has been paid to reading fluency. One reason might be that training studies often have failed to provide growth in reading rate in spite of the fact that the accuracy problem was remediated. Recent research has also indicated that, in languages with a consistent mapping between graphemes and phonemes, automatization of decoding processes are more difficult to reach than aquiring accurate decoding skills. Several studies have found that computer-based flashcard training seems to be a productive way to develop reading fluency. The aims of this thesis are partly to replicate some of the previous studies with time pressured exposure and partly to examine whether the condition with time pressure is more effective than the flashcard condition with fixed exposure duration. In the time pressure condition, the exposure duration was varied as a function of accuracy. This thesis reports one main study and two case studies. The participants in the main study were 17 males and 11 females between the ages of 11 and 17. All of them were poor readers, scoring below the 11th percentile on standardized reading test for their age group. The two participants of the first case study were the poorest readers of all. Their decoding strategies differed greatly. The younger of them, a slow reader in the fourth grade, can be seen as “a speller” with most impairment in the orthographic processing and the older, a quick reader in the fifth grade, can be seen as “a guesser” with most impairment in the phonological processing. The four participants in the second case study were moderately poor readers between the ages of 12 and 14. Each participant practiced the two different conditions of the computer-based flashcard training with spelling response in sessions about twenty minutes long twice to three times a week during three to four months. Teacher-controlled tuition was only given in some pre-sessions. According to the online results, all participants in both of the exposure conditions were capable of keeping the accuracy at a high level, i.e. fluent reading was expected to be developed. A battery of silent and oral reading tests and spelling-to-dictation tests was used in pre-, middle- and posttest. Both accuracy and rate were measured in reading. Except for “the speller” in the first case study, significant improvements were found on all tests for both conditions. The best progress was during the first training period independent of condition. Positive effects were found for both trained and untrained material and for words and pseudo-words. The reading progress has in general been better than the average student usually develops during the same time. The students reported the time pressured condition as being more effective and motivating but no significant difference was found between the two conditions in the pre- to posttests.
