Syftet med studien är att åskådliggöra hur talfamiljer upp till 10 förekommer och gestaltas i läroboksuppgifter i årskurs 1, utifrån ett problemlösningsperspektiv. För att uppfylla syftet analyseras läroboksuppgifter med talfamiljer och delar av talfamiljer genom Cummins analysmodell där uppgifterna sorteras på fyra olika nivåer beroende av kontext och kognitiv svårighetsgrad efter att de kategoriserats. Resultatet blev både kvantitativt och kvalitativt där det framgick att läromedel tränar elever i talfamiljernas delar helt fristående. Ytterst få läromedel visade på talfamiljernas samband mellan talets helhet och delar. Den vanligaste läroboksuppgiften är en naken uppgift med addition eller subtraktion som räknas från vänster till höger helt utan stöd av kontext som bilder. Studien lyfter även tankar kring vad aktuell forskning säger kontra hur läroboksuppgifter är utformade och vad den enskilda läraren behöver tänka på när den ska göra sitt val av uppgifter till sina elever. / The purpose of this essay is to illustrate how fact families are present and form part of teaching materials in Swedish schools` year 1. This study focuses on how text book assignments teaches number sense, number ability and fact families up to 10, from a problem-solving perspective. To fulfill the purpose of the essay, textbook assignments with fact families and parts of fact families are analyzed using Cummins´ analysis model, where the framework is sorted into four distinct levels depending on context and cognitive difficulty after categorization. The result was analyzed both quantitatively and qualitatively and showed that teaching materials train students in the part of facts completely independently. Very few teaching materials showed the relationship between the fact family and the whole and parts of addition and subtraction. The most common textbook task is a bare task with addition or subtraction that counts from left to right without the support of context. The study also raises thoughts about what the research shows versus how school books assignments are designed and also what the individual teacher needs to think about when making his or her choice of text book tasks for students. / <p>9 juni 2017</p>

No. of bitstreams: 1 dissertacao_carlos_pessoa.pdf: 1069290 bytes, checksum: 45b9ece9ccba3a6acfdd7eacfd9bf391 (MD5) Previous issue date: 2009-08-27 / This study titled "Jurisdiction and the power of fact enunciation: normalization in the interstices of the court act" aims to get close to the performance of magistrates and courts of the judiciary power (the court action), specifically in its activities related to the creation of official versions of facts. From the assumption that such activity is based on a specific state power, called in this study the power of fact enunciation, we will show that the court actions are composed by other powers required for its performance. Given this diversity of powers, this study questions what kind of authorities and what kind of legitimization procedures the society is subjected to, specifically the citizens in courts. Based on a critical-dualistic methodology, which divides facts and decisions, balanced by the theory of speech acts, from Searle, this study will try to understand the various forms of ilocucionary strength, which affect the court actions. In this direction, after questioning the means of justification for the judicial activity and verification of its legitimacy, this study will seek to understand the idea of modalization explained by a linguistics enunciation, which will be used to explain how to carry out normalization, found inside the State, in its court action. However, it should be highlighted that this study, although closer to the theory of speech acts, believes that it is possible to match this ideas with the critical dualism and with the theory of truth as correspondence. Finally, this study results in a theoretical discourse related not only to the needs to legitimize the normative activity in a Republican state (in the way of Arendt), and democracy, but also to the activity related to the creation of official versions for past happenings, through the power of the fact enunciation / A presente dissertação, intitulada ¯Jurisdição e poder de enunciação fática: a normalização nos interstícios do agir jurisdicional. tem por objetivo aproximar-se da atuação dos magistrados e tribunais do Poder Judiciário (o agir jurisdicional), especificamente em sua atuação relacionada com o estabelecimento de versões oficiais sobre os fatos. A partir da consideração de tal atuação como oriunda de um poder estatal próprio, denominado por este estudo de poder de enunciação fática, explicitar-se-á que o agir jurisdicional é formado por outros poderes necessários à atuação estatal. Diante dessa diversidade de poderes, o presente estudo indaga a respeito do tipo de autoridade e do tipo de procedimento de legitimação a que os cidadãos estão sujeitos, especificamente os jurisdicionados. Utilizando a metodologia crítico-dualista, que defende a cisão entre fatos e decisões, redimensionada pela teoria dos atos de fala, especificamente de Searle, o presente estudo procurará compreender as diversas formas de força ilocucionária envolvidas no agir jurisdicional. Nessa direção, após questionar as formas de justificação da atividade jurisdicional e da verificação de sua legitimidade, buscar-se-á compreender a ideia de modalização explicitada por uma linguística da enunciação, que será utilizada para explicar como se procede à normalização, verificada no interior do Estado, em seu agir jurisdicional. É importante ressaltar, contudo, que este estudo, apesar de se aproximar da teoria dos atos de fala, acredita ser possível a compatibilização de suas ideias com o dualismo crítico e com a teoria da verdade como correspondência. Por fim, este estudo dissertativo resulta em um direcionamento teórico não vinculado, apenas, à necessidade de legitimação da atividade normativa em um Estado republicano (nos moldes de Arendt) e democrático, mas também, da atividade relacionada com o estabelecimento de versões oficiais sobre fatos pretéritos, através do poder de enunciação fática

"Therefore, the aims of the study are to explore the origin, nature and purpose of fact-finding missions, to explore what is currently on the ground, to expose the inherent deficiencies in the current practice, which compromise the missions' capacity to promote and protect human and peoples' rights. Having identified the shortcomings, lessons and inspiration will be drawn from the practice and rules of procedure of other regional and international treaty monitoring bodies, particularly the Inter-American Commission on Human Rights (IACHR). The starting point of the analysis shall be to identify the various fact-finding related issues that arose in the response of the Government of Zimbabwe to the African Commission on Human and Peoples' Rights (ACHPR) report. A survey of the reaction and response of other countries in which similar fact-finding missions were conducted, shall be carried out to gauge the consistence or otherwise in the ACHPR's practice. It shall be strongly suggested that the ACHPR should substantially borrow from other human rights systems, if necessary. After closely observing these issues, the study will come up with a position and firm recommendations to the ACHPR in terms of which its practice can be revamped for the achievement of an effective and progressive promotion and protection of human and peoples' rights as contemplated by the African Charter. ... This study has four chapters. Chapter one constitutes introductory remarks putting the study into context and the justification thereof. Chapter two explores the nature, origin, forms and importance of fact-finding in human rights protection. It searches for the underlying principles governing credible and plausible fact-finding. Chapter three analyses the ACHPR fact-finding practice to see what is there and critically compare it to the IACHR, UN and ILO practice. It aims at demonstrating the strengths and weaknesses of the African system. Chapter four revisits the weaknesses unearthed in chapter three and proposes recommendations for overall improvement. The study concludes by soliciting draft rules of procedure from the general principles explored in chapter two, combined with lessons learnt from other systems in chapter three. The model fact-finding rules of procedures are marked Annexure A at the end of this work." -- Introduction. / Thesis (LLM)--University of Pretoria, 2005. / http://www.chr.up.ac.za/academic_pro/llm1/dissertations.html / Centre for Human Rights / LLM

[ES] En tiempos recientes, el desarrollo de las redes sociales y de las agencias de noticias han traído nuevos retos y amenazas a la web. Estas amenazas han llamado la atención de la comunidad investigadora en Procesamiento del Lenguaje Natural (PLN) ya que están contaminando las plataformas de redes sociales. Un ejemplo de amenaza serían las noticias falsas, en las que los usuarios difunden y comparten información falsa, inexacta o engañosa. La información falsa no se limita a la información verificable, sino que también incluye información que se utiliza con fines nocivos. Además, uno de los desafíos a los que se enfrentan los investigadores es la gran cantidad de usuarios en las plataformas de redes sociales, donde detectar a los difusores de información falsa no es tarea fácil. Los trabajos previos que se han propuesto para limitar o estudiar el tema de la detección de información falsa se han centrado en comprender el lenguaje de la información falsa desde una perspectiva lingüística. En el caso de información verificable, estos enfoques se han propuesto en un entorno monolingüe. Además, apenas se ha investigado la detección de las fuentes o los difusores de información falsa en las redes sociales. En esta tesis estudiamos la información falsa desde varias perspectivas. En primer lugar, dado que los trabajos anteriores se centraron en el estudio de la información falsa en un entorno monolingüe, en esta tesis estudiamos la información falsa en un entorno multilingüe. Proponemos diferentes enfoques multilingües y los comparamos con un conjunto de baselines monolingües. Además, proporcionamos estudios sistemáticos para los resultados de la evaluación de nuestros enfoques para una mejor comprensión. En segundo lugar, hemos notado que el papel de la información afectiva no se ha investigado en profundidad. Por lo tanto, la segunda parte de nuestro trabajo de investigación estudia el papel de la información afectiva en la información falsa y muestra cómo los autores de contenido falso la emplean para manipular al lector. Aquí, investigamos varios tipos de información falsa para comprender la correlación entre la información afectiva y cada tipo (Propaganda, Trucos / Engaños, Clickbait y Sátira). Por último, aunque no menos importante, en un intento de limitar su propagación, también abordamos el problema de los difusores de información falsa en las redes sociales. En esta dirección de la investigación, nos enfocamos en explotar varias características basadas en texto extraídas de los mensajes de perfiles en línea de tales difusores. Estudiamos diferentes conjuntos de características que pueden tener el potencial de ayudar a discriminar entre difusores de información falsa y verificadores de hechos. / [CA] En temps recents, el desenvolupament de les xarxes socials i de les agències de notícies han portat nous reptes i amenaces a la web.

La informació falsa no es limita a la informació verificable, sinó que també inclou informació que s'utilitza amb fins nocius. A més, un dels desafiaments als quals s'enfronten els investigadors és la gran quantitat d'usuaris en les plataformes de xarxes socials, on detectar els difusors d'informació falsa no és tasca fàcil.

These threats have taken the attention of the Natural Language Processing (NLP) research community as they are polluting the online social media platforms. One of the examples of these threats is false information, in which false, inaccurate, or deceptive information is spread and shared by online users. False information is not limited to verifiable information, but it also involves information that is used for harmful purposes. Also, one of the challenges that researchers have to face is the massive number of users in social media platforms, where detecting false information spreaders is not an easy job. Previous work that has been proposed for limiting or studying the issue of detecting false information has focused on understanding the language of false information from a linguistic perspective. In the case of verifiable information, approaches have been proposed in a monolingual setting. Moreover, detecting the sources or the spreaders of false information in social media has not been investigated much. In this thesis we study false information from several aspects. First, since previous work focused on studying false information in a monolingual setting, in this thesis we study false information in a cross-lingual one. We propose different cross-lingual approaches and we compare them to a set of monolingual baselines. Also, we provide systematic studies for the evaluation results of our approaches for better understanding. Second, we noticed that the role of affective information was not investigated in depth. Therefore, the second part of our research work studies the role of the affective information in false information and shows how the authors of false content use it to manipulate the reader. Here, we investigate several types of false information to understand the correlation between affective information and each type (Propaganda, Hoax, Clickbait, Rumor, and Satire). Last but not least, in an attempt to limit its spread, we also address the problem of detecting false information spreaders in social media. In this research direction, we focus on exploiting several text-based features extracted from the online profile messages of those spreaders. We study different feature sets that can have the potential to help to identify false information spreaders from fact checkers. / Ghanem, BHH. (2020).

Organizational decisions are significant to an organizations' future. Research shows that many organizations tend to make decisions based on previous experiences, ‘gut feeling’ and assumptions rather than facts. This is troubling since decision-makers leave the organization’s future to the hands of chance. It is impossible to foresee the future, but accurate factual data can be of guidance towards a successful path. The food industry is one industry which must undertake tremendous efficiency efforts due to current climate change in order to sustain a growing population while resources are diminishing. Therefore, organizations must be efficient with resource allocation. Here accurate decisions must be made. Much research has been conducted into the food industry regarding sustainability practices, and data-driven approaches have become widely regarded as promising in sustainability practices due to the new industry paradigm of industry 4.0 and availability of data. Fact-based decision making based on the collection, storage, and analysis of data has been widely studied and coined Business Intelligence &amp; Analytics (BI&amp;A). This study is based upon Scandinavian food producers and processors and explores the current adoption and utilization of BI&amp;A towards efficient production and its challenges. Through an explorative approach with interviews and analysis of organization reports, the current progress into BI&amp;A towards efficient production and accompanying challenges were identified. Findings show that BI&amp;A is applied to varying degrees for storage of data, and to monitor, analyze, and identify targets of action within energy consumption, food waste, material waste, and supply chain. Challenges identified were integration both internally within organizations and externally in the supply chain, economic, and leadership. To manage these challenges, managerial complications are provided. Further research could investigate the data collection processes in production, understanding the role of BI&amp;A for top managers in decision making, investigate BI&amp;A strategies towards efficient production, and provide empirical results from other parts of the supply chain.

In this Thesis, we leverage unsupervised raw data to develop more efficient pre-training objectives and self-supervised tasks that align well with downstream applications. In the first part, we present three alternative objectives to BERT’s Masked Language Modeling (MLM), namely Random Token Substitution (RTS), Cluster-based Random Token Substitution C-RTS, and Swapped Language Modeling (SLM). Unlike MLM, all of these proposals involve token swapping rather than replacing tokens with BERT’s [MASK]. RTS and C-RTS involve pre- dicting the originality of tokens, while SLM tasks the model at predicting the original token values. Each objective is applied to several models, which are trained using the same computational budget and corpora. Evaluation results reveal RTS and C-RTS require up to 45% less pre-training time while achieving performance on par with MLM. Notably, SLM outperforms MLM on several Answer Sentence Selection and GLUE tasks, despite utilizing the same computational budget for pre-training. In the second part of the Thesis, we propose self-supervised pre-training tasks that exhibit structural alignment with downstream applications, leading to improved performance and reduced reliance on labeled data to achieve comparable results. We exploit the weak supervision provided by large corpora like Wikipedia and CC-News, challenging the model to recognize whether spans of text originate from the same paragraph or document. To this end, we design (i) a pre-training objective that targets multi-sentence inference models by performing predictions over multiple spans of texts simultaneously, (ii) self-supervised objectives tailored to enhance performance in Answer Sentence Selection and its Contextual version, and (iii) a pre-training objective aimed at performance improvements in Summarization. Through continuous pre-training, starting from renowned checkpoints such as RoBERTa, ELEC- TRA, DeBERTa, BART, and T5, we demonstrate that our models achieve higher performance on Fact Verification, Answer Sentence Selection, and Summarization. We extensively evaluate our proposals on different benchmarks, revealing significant accuracy gains, particularly when annotation in the target dataset is limited. Notably, we achieve state-of-the-art results on the development set of the FEVER dataset and results close to state-of-the-art models using much more parameters on the test set. Furthermore, our objectives enable us to attain state-of-the-art results on ASNQ, WikiQA, and TREC-QA test sets, across all evaluation metrics (MAP, MRR, and P@1). For Summarization, our objective enhances summary quality, as measured by various metrics like ROUGE and BLEURT. We maintain that our proposals can be seamlessly combined with other techniques from recently proposed works, as they do not require alterations to the internal structure of Transformer models but only involve modifications to the training tasks.

La version intégrale de ce mémoire [ou de cette thèse] est disponible uniquement pour consultation individuelle à la Bibliothèque de musique de l’Université de Montréal (www.bib.umontreal.ca/MU) / Instants et espaces investis par la musique, les sessions sont actuellement en Irlande un marqueur d’expression culturelle. En surface, celles-ci peuvent être définies en tant que regroupement prévu ou spontané de plusieurs musiciens dans le but de faire de la musique et de passer un agréable moment en communauté. Toutefois, un travail d'enquête réparti sur sept années de recherches dans le nord-ouest irlandais a révélé qu'en profondeur, les sessions représentent un phénomène socioculturel complexe, phénomène social autant que musical, fait musical autant que social, édifice symbolique mixte tissé d'interactions dont la combinatoire à chaque fois renouvelée implique un jeu de relations entre le facteur individuel et les stratégies collectives qui, radicalement, affectent l’ensemble de la structure de l’événement. Comprendre le fonctionnement d'une session revient alors à poser un certain nombre de questions ayant pour finalité de révéler la manière dont les deux pôles du social et du musical se trouvent, en même temps que distincts, inextricablement liés. Les sessions musicales se révèlent ainsi sources d'un certain nombre de problèmes, lesquels, a priori motivés par une connaissance spécifique à notre objet d'étude, conduisent à dépasser le domaine exclusif de l'Irlande pour venir affronter les questionnements plus larges que pose l'ethnomusicologie contemporaine. La présente thèse s'organise en cinq chapitres. Un premier est consacré à une description générale des sessions. L'attention est portée sur les liens dynamiques opérant entre ce qui relève du musical et ce qui procède d'un ordre plus spécifiquement social. Les questions alors soulevées engagent un second chapitre, dont l'organisation est bipartite. Y sont alors exposés, dans un premier temps, les grands axes problématiques sur lesquels cette thèse repose, et dans un second, les réponses méthodologiques impliquées par cette même problématique. Un troisième chapitre consiste à mettre en place l'ensemble des outils nécessaires à la conduite des analyses, à travers une réflexion portant sur les propriétés systématiques de l'ensemble des paramètres sociaux et musicaux caractéristiques de ce que sera notre corpus. L'étape suivante, quatrième chapitre de la thèse, se fonde sur les analyses comparatives d'un corpus de 26 pièces musicales, collectées dans le cadre de 7 situations de sessions distinctes. À travers un cinquième chapitre, le travail se termine enfin par une synthèse fondée sur l'intégralité des résultats analytiques obtenus dans le chapitre précédent. / As periods of time and spatial entities invested by music, sessions in Ireland nowadays are a marker of cultural expression. Superficially, those can be defined as a gathering, planned or spontaneous, of several musicians with the prospect to produce music and to share a nice moment together. Yet, a survey pursued over a seven-year research work in north-western Ireland revealed that, in depth, sessions represent complex socio-cultural events, social as much as musical, musical as well as social happening, symbolic entity enriched by interactions whose permanently renewed combination reflects the interplay between individual factors and group strategies, that, radically, affect the whole structure of the event. To understand how a session functions then requires raising a number of questions whose end is to elucidate how the two poles, social and musical, happen to be inextricably linked, though distinct at the same time. Musical sessions thus become a source of problems which, a priori connected to the amount of knowledge specific of our topic, lead to overcome the exclusive domain of Ireland up to facing the broader issues of contemporary ethnomusicology. The present thesis includes five chapters. The first one is a general description of sessions. Attention is paid to the dynamic links operating between what belongs to music and what proceeds from a line more specifically social. Questions then raised trigger a second chapter, whose content is bipartite. First are exposed the major problems on which the thesis rests, and secondly the methodological answers related to the given problematic. A third chapter consists of setting the spectrum of methods required to conduct analyses, through a reflexion bearing on the system properties of the whole range of social and musical parameters that characterize this work. Next step, the fourth chapter is based on the comparative analysis of 26 musical pieces that were collected in the context of seven different situations in distinct sessions. In the fifth chapter, the thesis ends with a synthesis of all analytical results as gathered in the previous chapters.

En matière d’interprétation juridique, le rôle du juge se déroule entre le fait et le droit. Le juge est chargé non seulement d’analyser et de déterminer les éléments factuels, mais il a aussi, pour objectif, d’exercer la qualification du fait et d’appliquer les règles de droit. C’est la raison pour laquelle l’interprétation juridique est en générale divisée en deux aspects : l’interprétation du fait et celle du droit (ou de la loi). L’interprétation du contrat participe, en principe, au premier aspect. Précisément, la loi, en tant que règle générale et abstraite, est l’expression de la volonté générale, alors que le contrat n’est que la traduction de plusieurs volontés particulières. Le projet de cette thèse cherche à analyser les problématiques provoquées par la théorie et la pratique de l’interprétation du contrat : dans quelle condition le juge peut-il exercer son pouvoir d’interprétation du contrat ? Interpréter un contrat, c’est interpréter la commune intention des parties ou plutôt interpréter un rapport contractuel intégré dans la vie sociale et économique ? L’interprétation du contrat peut-elle combler les lacunes du contrat ? Les règles d’ordre public peuvent-elles devenir le fondement de l’interprétation du contrat ? La correction du contenu du contrat a-t-elle besoin de participation de l’interprétation du contrat ? La recherche des problématiques exposées ci-dessus détermine, en effet, l’intérêt du projet de cette thèse. Théoriquement, le travail de thèse défie la définition traditionnelle de l’interprétation du contrat, en glosant de nouveau sur le sens et l’esprit des règles classiques d’interprétation, et en analysant le rôle des règles d’ordre public dans l’interprétation du contrat. Pratiquement, le travail de thèse se fonde sur une recherche approfondie des fonctions de l’interprétation du contrat dans les activités judiciaires. / In terms of the legal interpretation, the role of the judge takes place between the facts and the law. The judge is not only charged with analyzing and determining the factual elements, but he also aims to exercise the qualification of the fact and apply the rules of law. This is why legal interpretation is generally divided into two aspects, i.e. the interpretation of the fact and that of the law. The interpretation of the contract, in principle, belongs to the first aspect. More precisely, the law, as general and abstract rule, is the expression of the general will, while the contract is only a translation of several individual wills. This dissertation analyzes the issues aroused by the theory and practice of the interpretation of the contract: In what condition can the judge exercise his capacity of interpretation of the contract? Should the interpretation of the contract aim exclusively at the common intention of the parties or aim not only at the will of the contracting parties but also the internal and external objective elements of the contract? Can the interpretation of the contract fill in the lacunas of the contract? Can the rules of public order become the foundation of the interpretation of the contract? Does the correction of the content of the contract need the participation of the interpretation of the contract? The research of the above mentioned issues determines, in fact, the interest of the plan of this dissertation. Theoretically, the work of this dissertation challenges the traditional definition of the interpretation of the contract, by annotating again the sense and the spirit of the classic rules of interpretation, and analyzing the role of the rules of public order in the interpretation of the contract. In practice, the work of this dissertation is founded on a profound research of the functions of the interpretation of the contract in the judiciary activities.
