Este trabalho é uma proposta de prática de leitura intertextual (para os terceiro e quarto ciclos do Ensino Fundamental) em que o fenômeno da intertextualidade, mostrado sob pontos de vista de vários autores, é considerado potencializador e enriquecedor da leitura, colaborando para a formação de um leitor mais proficiente e mais preparado para enfrentar as demandas do mundo letrado. Propõem-se, na exploração textual, atividades inferenciais (para as quais o aluno comparece com conhecimentos linguísticos e extralinguísticos) que podem levá-lo a estabelecer relações não só entre os elementos do texto em si, mas também entre esse texto e outros textos e entre esse texto e sua realidade. Muitas vezes a leitura do aluno não é plena por falta de conhecimentos prévios. A interferência do mediador, leitor mais maduro, torna-se, então, desejável e necessária, para melhoria no nível de adequação da leitura, ampliação do universo do leitor iniciante e aquisição de mecanismos metacognitivos. Ao clarificar zonas de intersecção (identificação do intertexto), por meio de procedimentos discursivos, propicia-se não só o reconhecimento do diálogo intertextual como também uma interpretação mais completa do texto (com a leitura dos implícitos), incluindo casos de polifonia (presença de vozes variadas no texto) e a busca da intencionalidade e do posicionamento ideológico do autor. O texto é considerado a principal matéria-prima do professor de Português. Paradoxalmente, o desempenho dos alunos das escolas públicas e particulares deixa a desejar no quesito leitura. Uma configuração do leitor-aprendiz em seus aspectos sociocognitivos e algumas considerações sobre o modo como são realizadas as atividades de leitura na sala de aula visam mostrar a necessidade de um interlocutor que proponha relações dialógicas e mais significativas no embate com o texto, ampliando, inclusive o leque de opções para gêneros variados, sem barreiras de tempo, de espaço, de estilo, de modalidade, de nacionalidade. Tendo por base a noção de mediação e de zona de desenvolvimento proximal em Vygotsky e a de interação verbal em Bakhtin; as análises de Marcuschi e Rocco sobre o papel da escola e do material didático na formação do leitor; bem como os princípios da Análise do Discurso, da Teoria da Enunciação e da Linguística Textual, sustentados por Genette, Maingueneau, Authier-Revuz, Brandão, Koch, Van Dijk e SantAnna, sugerem-se alguns exemplos de análise para demonstrar a exequibilidade da proposta. Finalmente, a intertextualidade é vinculada à interdisciplinaridade, concluindo-se que a leitura é, hoje, um poderoso auxiliar no intercâmbio de informações do mundo eletrônico-globalizado; na constituição de um leitor-sujeito consciente, ético e crítico; na transformação do aprendiz em cidadão; na conquista de um instrumento de busca interior. Procura-se provar, enfim, que a leitura, como senha para o conhecimento, pode levar ao poder e, como senha para o autoconhecimento, pode levar à sabedoria. / This essay is an intertextual reading practice proposal (for the third and fourth cycles of elementary school) in which the intertextuality phenomenon, shown by various authors opinions, enhances and enriches the reading process, contributing to develop a more proficient and prepared reader, capable of facing the literate world demands. Through textual exploration, inferential activities are proposed (for which the student has linguistic and extra linguistic knowledge) which can lead the student not only to establish relationships between elements of the text itself, but also between this text and other texts and between this text and its own reality. Often the reading process is not complete due to the lack of prior knowledge by the students. The mediator interference, a more mature reader, becomes then desirable and necessary to improve the adequacy of the reading process, to expand the beginner reader universe and to acquire metacognitive mechanisms. By clarifying intersection zones (intertext identification), through discursive procedures, there is not only the inter-textual dialogue recognition but also a more complete text interpretation (by the implicit reading) including polyphony cases (presence of various voices in the text) and the pursuit of the intentionality and the ideological positioning of the author. The text is considered the main raw material of the Portuguese teacher. Paradoxically, the performance of public and private schools students is still weak in the reading aspect. The configuration of the learner-reader in their social-cognitive aspects and a few considerations about how the reading activities are led in the classroom aim to show the need for an interlocutor who can propose dialogical and more meaningful relationships in the fight with the text, also expanding the range of options for different genres, with no time, space, style, modality, nationality barriers. Based on Vygotsky\'s notion of mediation and proximal development zone and on Bakhtins verbal interaction; Marcuschi and Roccos analysis on the role of school and didactic materials in the readers development; as well as the Discourse Analysis, the Theory of Enunciation and the Textual Linguistics principles, supported by Genette, Maingueneau, Authier-Revuz, Brandão, Koch, Van Dijk and Sant\'Anna, some examples of analysis are suggested to demonstrate the feasibility of the proposal. Finally, intertextuality is linked to interdisciplinary and the conclusion is that reading is nowadays a powerful tool to enhance information exchange in the globalized world; in the constitution of an ethical and critical reader-conscious subject; transforming learners in citizens who can conquer a tool of internal search. This document attempts to prove that reading, as a password for knowledge, can lead to power and, as the password for the self- knowledge, can lead to wisdom.

This thesis is composed of six papers, all dealing with the issue of sampling from a finite population. We consider two different topics: real time sampling and distributions in sampling. The main focus is on Papers A–C, where a somewhat special sampling situation referred to as real time sampling is studied. Here a finite population passes or is passed by the sampler. There is no list of the population units available and for every unit the sampler should decide whether or not to sample it when he/she meets the unit. We focus on the problem of finding suitable sampling methods for the described situation and some new methods are proposed. In all, we try not to sample units close to each other so often, i.e. we sample with negative dependencies. Here the correlations between the inclusion indicators, called sampling correlations, play an important role. Some evaluation of the new methods are made by using a simulation study and asymptotic calculations. We study new methods mainly in comparison to standard Bernoulli sampling while having the sample mean as an estimator for the population mean. Assuming a stationary population model with decreasing autocorrelations, we have found the form for the nearly optimal sampling correlations by using asymptotic calculations. Here some restrictions on the sampling correlations are used. We gain most in efficiency using methods that give negatively correlated indicator variables, such that the correlation sum is small and the sampling correlations are equal for units up to lag m apart and zero afterwards. Since the proposed methods are based on sequences of dependent Bernoulli variables, an important part of the study is devoted to the problem of how to generate such sequences. The correlation structure of these sequences is also studied. The remainder of the thesis consists of three diverse papers, Papers D–F, where distributional properties in survey sampling are considered. In Paper D the concern is with unified statistical inference. Here both the model for the population and the sampling design are taken into account when considering the properties of an estimator. In this paper the framework of the sampling design as a multivariate distribution is used to outline two-phase sampling. In Paper E, we give probability functions for different sampling designs such as conditional Poisson, Sampford and Pareto designs. Methods to sample by using the probability function of a sampling design are discussed. Paper F focuses on the design-based distributional characteristics of the π-estimator and its variance estimator. We give formulae for the higher-order moments and cumulants of the π-estimator. Formulae of the design-based variance of the variance estimator, and covariance of the π-estimator and its variance estimator are presented.

It is imperative to prepare South African learners to participate and function confidently within the context of a rapidly changing world. The curriculum of the South African Education System emphasises the significance of optimising learners‟ cognitive development as early as pre-school age to enable them to become creative and critical citizens who lead purposeful lives in a safe and prejudice-free environment. Despite continuous efforts by educators to optimise cognitive development, recently executed research studies indicate that cognitive development has not been adequately optimised in South African schools. This study was undertaken to establish the cognitive development level (cognitive and meta-cognitive skills and strategies, cognitive functions and non-intellective factors) of Grade R-learners and to determine the effect of an intervention programme, the Cognitive Enhancement Programme for Pre-schoolers (CEPP), on their cognitive development. By means of a literature study, I investigated whether, to what extent the cognitive development of Grade R-learners was taking place, and established which cognitive and meta-cognitive thinking skills and strategies, cognitive functions and non-intellective factors are required for effective cognitive development among Grade R-learners. In addition to this, the role of mediation for optimising cognitive development was investigated. A concurrent embedded mixed methods design was conducted in the implementation of the research. Intervention research within a quasi-experimental research design was applied. The data collection by means of a quantitative strategy (quasi-experimental research) and qualitative strategy (observation study) was executed simultaneously. By means of convenient sampling, one Grade R-class with twenty learners was subjected to a pre-test to establish their cognitive developmental level. The test results as well as the observations conducted during the pre-test revealed that the learners experienced problems related to their cognitive development. Ten of the twenty learners were then divided purposively based on their test performance into two experimental groups, Experimental Group A and Experimental Group B consisting of five participants each. Experimental group A and Experimental Group B took part in the CEPP intervention based on the principles of mediation on a rotational basis over a period of twelve weeks, during which intentional attempts were made to optimise their cognitive development. Both groups completed a post-test and delayed post-test (retention) to determine the effect of the CEPP intervention on their cognitive development. In addition to the test results, observations in the form of structured running and anecdotal records and reflective notes were utilised to understand the nature and quality of the cognitive development of the learners better. Furthermore, the effect of the intervention on their cognitive development was established. The cognitive development of Grade R-learners who participated in this study was optimised, which is a clear indication that cognitive capacity can be optimised when instruction is based on the principles of mediation / PhD, Teaching and Learning, North-West University, Vaal Triangle Campus, 2012

Le trouble obsessionnel-compulsif (TOC) se caractérise par la présence d’obsessions et/ou de compulsions. À la lumière de l’hétérogénéité du TOC et de la présence de styles de pensées et de comportements de type TOC chez des personnes présentant d’autres problèmes de santé mentale, certains ont fait valoir la nécessité de créer une catégorie des troubles du spectre obsessionnel-compulsif et d’identifier les processus cognitifs communs qui sous-tendent ces troubles afin d’élaborer des théories et des traitements plus parcimonieux. Une tendance générale à douter de ses sens et de ses facultés cognitives semble être le pivot des troubles obsessionnels. Selon l’approche basée sur les inférences, le doute obsessionnel est suscité par un processus de raisonnement erroné, soit la confusion inférentielle (CI). La CI implique (1) une méfiance vis-à-vis des sens et (2) une importance indue accordée aux possibilités imaginaires. La faible confiance cognitive (CC), un processus cognitif similaire, renvoie à une méfiance par rapport à son attention, sa perception et sa mémoire. Cette thèse a visé à étudier la CI et la faible CC en tant que potentiels facteurs cognitifs transdiagnostiques dans le spectre de l’obsessionnalité. Le premier article constitue une revue systématique avec méta-analyse destinée à évaluer le rôle de la CC pour différents sous-types du TOC et à examiner à quel degré la faible CC est associée aux symptômes du TOC. On a constaté que les individus atteints d’un TOC présentent une plus faible CC que les témoins sains, mais que celle-ci ne semble pas spécifique au TOC. L’article a aussi souligné la nécessité d’employer des tâches idiosyncratiques, ciblant les distorsions de la pensée propres au TOC, afin de bien mesurer la CC. Dans le cadre du deuxième article, le but a été d’approfondir cette piste de recherche en examinant le rôle commun de la faible CC et de la CI pour les différents sous-types du TOC, en procédant à des analyses de grappes avec un échantillon de 128 patients atteints d’un TOC. Alors qu’il a été constaté que la faible CC correspondait davantage aux sous-types de vérification et « tout à fait juste », la CI semble pertinente pour un plus large éventail de profils TOC. Le troisième article examine le rôle de la CI chez les troubles des conduites alimentaires (TCAs) en provoquant la CI expérimentalement. Des participantes atteintes d’un TA (n = 18) et des femmes témoins saines (n = 18) ont été assignées à l’une des deux conditions expérimentales : pour la condition CI élevée, les participantes ont visionné des vidéos où des séquences clés étaient manquantes, ce qui suscitait la CI; pour la condition CI faible, les participantes ont visionné les vidéos intégrales. Chez le groupe TA assigné à la condition CI élevée, on a observé une tendance à présenter un état de CI post-vidéos supérieur, un recours accru au comportement de neutralisation et, enfin, davantage de symptômes TOC. En somme, les résultats de cette thèse soulignent la pertinence de la CI et de la faible CC en tant que facteurs cognitifs transdiagnostiques sur le spectre obsessionnel-compulsif. / Obsessive-compulsive disorder (OCD) is a severe mental health disorder that involves obsessions and/or compulsions. In light of the heterogeneity of OCD and of the presence of OCD-like thinking and behaviors in several disorders, some have argued for the necessity of a new category of obsessive-compulsive spectrum disorders. Considering the overlap between various disorders characterized by obsessionality, there is a need for the identification of common cognitive processes that underpin these disorders in order to formulate more parsimonious explanations and treatments for these conditions. A general tendency to doubt the senses and cognitive faculties appears as central to obsessional disorders. According to the inference-based approach, the obsessional doubt is elicited by a faulty reasoning process known as inferential confusion (IC), that implicates (1) a distrust of the senses, and (2) an investment in imaginary possibilities. A similar construct is low cognitive confidence, which is defined as a distrust of one’s attention, perception and memory. The overarching goal of this thesis was to examine IC and low cognitive confidence as potential transdiagnostic cognitive factors across the spectrum of obsessionality. The first thesis article evaluated the role of cognitive confidence across OCD subtypes and examined the extent to which poor cognitive confidence is associated with OCD symptomatology by conducting a systematic review with a meta-analysis. This article led to the conclusion that individuals with OCD have lower cognitive confidence than healthy controls, but that it is unclear if cognitive confidence is specific to OCD, such that the use of idiosyncratic tasks appears to be required in order to correctly capture cognitive confidence in OCD. The second thesis article furthered this investigation by examining the joint role of low cognitive confidence and IC across OCD subtypes by performing cluster analyses using a sample of 128 individuals with OCD. While cognitive confidence was found to more relevant to the checking and “just right” subtypes, IC appeared to be relevant to a wider range of OCD profiles. The third thesis article sought to examine the role of IC in eating disorders by inducing IC experimentally. Female participants with an eating disorder (n = 18) and healthy controls participants (n = 18) were recruited. Participants were assigned to one of two experimental conditions: in the High IC condition, participants watched videos with key sequences missing – provoking a distrust of the senses and lending more space for the imagination, thus triggering IC. In the Low IC condition, participants watched videos without sequences missing. The eating disorder group assigned to the High IC condition demonstrated a trend for higher levels of state IC, greater neutralization behavior and higher OCD symptoms than those who were assigned to the Low IC condition. Taken together, the results of the present thesis underline the relevance of IC and cognitive confidence as transdiagnostic cognitive factors across the obsessive-compulsive spectrum.

Durant leur parcours au secondaire (12 à 17 ans), les élèves sont amenés à résoudre des problèmes de preuves en classe de mathématiques (MELS, 2006a, 2006b). En géométrie, ces preuves doivent s’appuyer sur un référentiel théorique composé de propriétés et de définitions (Kuzniak et Richard, 2014). Afin de dégager les particularités des référentiels utilisés en classe, nous avons relevé et analysé les propriétés et les définitions de dix-neuf ouvrages scolaires québécois de 1re secondaire à la 5e secondaire. Chacun des éléments ainsi relevés a été identifié selon les concepts sous-tendus dans leurs énoncés, leurs valeurs épistémiques possibles, leur dépendance à une figure et leur place au sein du chapitre. Cette étude se base sur le concept des paradigmes géométriques (Houdement et Kuzniak, 2006) et le modèle des Espaces de Travail Mathématique (ETM) (Kuzniak et Richard, 2014) où le référentiel fait partie de la genèse discursive engendrée par un travail mathématique. L’étude des référentiels montre que plusieurs modalités discursives dans leur enseignement peuvent générer des difficultés lorsque vient le temps de les utiliser dans une preuve. Cette étude confirme aussi l’oscillation entre les paradigmes géométriques (Gauthier, 2015; Tanguay et Geeraerts, 2012) dans l’enseignement de la géométrie. Enfin, nous proposons un référentiel possible pour un agent tuteur d’aide à la démonstration selon le curriculum québécois. / During their high school career (12 to 17 years old), students are required to solve proof-based problems in their mathematics classes (MELS, 2006a, 2006b). In geometry, these mathemactical proofs must be supported by a theoretical referential of properties and definitions (Kuzniak et Richard, 2014). To determine the specifics of the referentials used in classes, we noted and analyzed the properties and definitions of nineteen Quebec secondary school textbooks. Each item was identified according to the concepts underlying in their statements, their possible epistemic value, their reliance on a figure, and their placement in the chapter. This study is based on the concept of geometric paradigms (Houdement et Kuzniak, 2006) and on the Mathematical Working Space model (MWS or ETM in French) (Kuzniak et Richard, 2014) where the referential is part of the discursive genesis generated by a mathematical work. This study on referentials demonstrates that there are many discursive modalities used in teaching, which can produce difficulties when they are required to be used in a proof. This study also confirms the oscillation between the geometric paradigms (Gauthier, 2015; Tanguay et Geeraerts, 2012) when teaching geometry. Furthermore, we propose a possible referential to be used in a demonstration aid tutor in accordance with Quebec’s curriculum.
