The works of jurist Louis Le Caron (1534-1613) are part of a body of doxological writings by a school of humanists who repudiated Aristotelian scholasticism. In the Dialogues (1556), Le Caron elaborated a theory of poetics as well as a vision of the cosmos and of man encompassing political, aesthetic, ethical and epistemological perspectives. The Dialogues can be regarded as an example of absolute idealism because their philosophical underpinnings echo the neo-Platonic tradition. This being said, the way the book's arguments are organized into dialogues demonstrates an ideological shift which, in the middle of the century, progressively undermined the current monolithic vision rooted in theology. Thus, the structure of the Dialogues reveals a new emphasis on a field of knowledge largely ignored by Platonism: that of transformation and becoming, the object of opinion rather than of rational certainty.

This qualitative interview study examines challenges college students may experience in extracurricular dialogues on contested sociopolitical issues. It also discusses approaches that students claim support them through the challenges of contested issues dialogues. This study found that college students encountered challenges including difficulty expressing disagreement, tensions related to their identities and group representation, and difficulty building trust and openness with peers in dialogue. Despite these difficulties, students also developed skills and capacities to bridge differences, to build community within dialogue, as well as to learn about themselves, others and sociopolitical issues. Through participants' accounts on how they perceive and negotiate these challenges, the study is intended to portray in-depth student perspectives about this critical aspect of peer dialogues on sociopolitical issues.

Ellipsis is a phenomenon whereby constituents which are normally obligatory in the grammar are omitted in actual discourse. It is found in all types of discourse, from everyday conversation to poetry. The omitted constituents can range from one word to an entire clause, and recovery of the ellipted item depends sometimes on the linguistic and sometimes on the non-linguistic context. From a practical point of view, the contribution of ellipsis in the context is twofold. First, it is one of several important means of achieving cohesion in a text. Secondly, ellipsis contributes to communicative appropriateness determined by the type of linguistic activity (e.g., narrative, casual conversation), the mode of communication (e.g., written / spoken) and the relationship between participants. The aim of this research is to provide a description of the functions of elliptical utterances – textual and interpersonal – in English and Japanese, based on a cross-linguistic analysis of dialogues in the English and Japanese map task corpora. In order to analyse ellipsis in relation to its two key functions, elliptical clauses in the map task dialogues were examined. I discuss how ellipsis is used to realise cohesion in the map task dialogues. The findings challenge the well-known claim that topics are established by full noun phrases, which are subsequently realised by pronouns (English) and null pronouns (Japanese). Rather, the results suggest that full noun phrases are used for topic continuity in both languages. Constituents which are ellipted in an utterance are identified and related to the moves types which the utterance realises within the exchange structure. The ellipted elements will be categorised according to the constituent types (Subject, Finite, Predicator, Complement and Adjunct), using the systemic functional approach. This analysis reveals that whereas in the English dialogues the most common types of ellipsis are that of Subject and Finite elements, in the Japanese dialogues the most common type is that of Subject. Types of ellipsis are also correlated with speech acts in the dialogues. The relation between types of ellipsis and particular speech acts associated with them is strikingly similar in the English and Japanese dialogues, despite the notable difference in grammar and pragmatics between the two languages. This analysis also shows how these types of ellipsis are associated with interpersonal effects in particular speech acts: ellipsis of Subject and Finite can contribute to a sharp contrast in the question and answer sequence, while Subject ellipsis in Japanese can contribute to modifying the command-like force in giving instructions. These effects can be summed up as epistemic and deontic modality respectively. Ultimately, it is argued that some types of ellipsis can serve as modality expressions. Additionally, in comparison to the way of realising the speech act of giving instructions in the English dialogues, it emerges that the Japanese speakers exploit ellipsis, which seems to be associated with lowering the degree of the speaker’s commitment to the proposition. As implications for pedagogical settings, I present pedagogical descriptions of ellipsis for Japanese learners of English and English learners of Japanese. Since the description is for specific learners, the approach which takes the difference in grammar and pragmatics between the two languages is made possible. Although descriptions state some detailed facts of ellipsis in English and Japanese, primarily highlighted is the importance of raising awareness of elliptical forms for particular functions in particular contexts. As ellipsis is a product of forms, functions and contexts, it is a most remarkable feature of spoken language. Spoken language is claimed by some researchers to show similar linguistic features among languages because of the restrictions inherent in the medium on communication. In the form of pedagogical description, I show the similarities and differences in ellipsis which derive from the grammar and pragmatics of each language, which are observed in the preceding linguistic research. Through the presentation of the findings which are modified for learners, learners will know how languages show convergence and divergence cross-linguistically.

O objetivo deste trabalho é fornecer uma análise de formas contemporâneas de pensamento e atitudes fundamentalistas à luz do filósofo italiano Gianni Vattimo, que postula que existiriam duas maneiras de pensar no processo de interpretação e construção do sentido: uma forte, que pressupõe uma verdade absoluta, e a outra fraca, que pressupõe uma verdade construída, o que não implica uma ação fraca, mas a abertura de possibilidades para mudanças profundas. O processo de construção da verdade forte produz verdades violentas, no sentido de que exclui outras verdades concorrentes. Neste trabalho, tomamos como base os fundamentalismos religiosos para refletir sobre outras formas atuais de fundamentalismo. O trabalho representa uma tentativa para evitar diferentes confrontos violentos entre variados pensamentos fundamentalistas. / The objective of this work is to provide an analysis of contemporary forms of fundamentalist thought and attitudes, in line with the Italian philosopher Gianni Vattimo, who postulates that there are two ways of thinking in the process of interpretation and meaning making: a strong one, which presupposes an absolute truth, and a weak one, which presupposes a constructed truth though not implying a weak possibility of action, but an opening of new possibilities for profound changes instead. The process of truth construction produces violent truths in the sense that it strongly excludes other competing truths. In this research, forms of religious fundamentalism are taken as starting points in a reflection on other present-day forms of fundamentalism. This work aims at the avoidance of various violent confrontations among several kinds of fundamentalist thoughts.

For more than 30 years, the problem of providing a formal framework for modeling dialogues has been a topic of great interest for the scientific areas of Linguistics, Philosophy, Cognitive Science, Formal Languages, Software Engineering and Artificial Intelligence. In the beginning the goal was to develop a "conversational computer", an automated system that could engage in a conversation in the same way as humans do. After studies showed the difficulties of achieving this goal Formal Language Theory and Artificial Intelligence have contributed to Dialogue Theory with the study and simulation of machine to machine and human to machine dialogues inspired by Linguistic studies of human interactions. The aim of our thesis is to propose a formal approach for the study of dialogues. Our work is an interdisciplinary one that connects theories and results in Dialogue Theory mainly from Formal Language Theory, but also from another areas like Artificial Intelligence, Linguistics and Multiprogramming. We contribute to Dialogue Theory by introducing a hierarchy of formal frameworks for the definition of protocols for dialogue interaction. Each framework defines a transition system in which dialogue protocols might be uniformly expressed and compared. The frameworks we propose are based on finite state transition systems and Grammar systems from Formal Language Theory and a multi-agent language for the specification of dialogue protocols from Artificial Intelligence. Grammar System Theory is a subfield of Formal Language Theory that studies how several (a finite number) of language defining devices (language processors or grammars) jointly develop a common symbolic environment (a string or a finite set of strings) by the application of language operations (for instance rewriting rules). For the frameworks we propose we study some of their formal properties, we compare their expressiveness, we investigate their practical application in Dialogue Theory and we analyze their connection with theories of human-like conversation from Linguistics. In addition we contribute to Grammar System Theory by proposing a new approach for the verification and derivation of Grammar systems. We analyze possible advantages of interpreting grammars as multiprograms that are susceptible of verification and derivation using the Owicki-Gries logic, a Hoare-based logic from the Multiprogramming field.

Intelligent Tutoring Systems (ITSs) have been shown to significantly improve students' learning in a variety of domains, including physics, mathematics, and thermodynamics. Tutorial dialogues is one of the strategies used by ITSs and has been empirically shown to significantly improve learning. This project investigates how different students interact with the tutorial dialogues in EER-Tutor, using both eye-gaze data and student-system interaction logs. EER-Tutor is a constraint-based ITS that teaches conceptual database design. In order to have a more comprehensive and accurate picture of a user's interactions with a learning environment, we need to know which interface features s/he visually inspected, what strategies s/he used and what cognitive efforts s/he made to complete tasks. Such knowledge allows intelligent systems to be proactive, rather than reactive, to users' actions. Eye-movement tracking is therefore a potential source of real-time adaptation in a learning environment. Our findings indicate that advanced students are selective of the interface areas they visually focus on whereas novices waste time by paying attention to interface areas that are inappropriate for the task at hand. Novices are also unaware that they need help with understanding the domain concepts discussed in the tutorial dialogues. We were able to accurately classify students, for example as novice or advanced students, using only eye-gaze or EER-Tutor log data as well as a combination of EER-Tutor and eye-gaze features. The cost of eye-tracking is justified as classifiers using only eye-gaze features sometimes perform as well as those utilising both EER-Tutor and eye-gaze data and outperform classifiers using only EER-Tutor data. The ability to classify students will therefore allow an ITS to intervene when needed and better guide students' learning if it detects sub-optimal behaviour.

This study grew out of my work with Maggie, a teacher at Blueberry Vale elementary school in suburban western Canada. Maggie and I began to use cogenerative dialogues after we identified and sought a method to address a number of issues in her class. Cogenerative dialogue praxis is meetings of students, teachers, researchers, and others designed to facilitate the process of improving the teaching and learning taking place. To this time this praxis has been used exclusively at the secondary education level. As such this study developed its overarching question: what will happen when cogenerative dialogue praxis is introduced to an elementary school class? To address this question I focus on: the activities in question and try to account for the various mediating factors each action experiences; human agency, which helped me understand the role the individuals play in instigating change to the system; and an ethical understanding of responsibility. From this analysis I form these specific claims: Cogenerative dialogue praxis is an authentic research tool which, when conducted properly, can address some of the ethical issues inherent in classroom research; cogenerative dialogue praxis facilitates the discussion of the ethical issues that are part of the research setting (e.g., class); cogenerative dialogue praxis is one viable solution for teachers to ethically mediate the various activity systems that constitute a class; cogenerative dialogue praxis contains internal contradictions such that there is the potential for its openness to collapse by its openness to any comment; a significant amount of time may be spent “unfocused,” during cogenerative dialogues but many of these moments can be contextualized positively in terms of building relationships, introducing new teaching topics, and so on; during my cogenerative dialogues the group developed and implemented a model to address a problem through cycles of expansive learning; and finally I learned from Maggie how teachers work with researchers, as researchers, evaluate their own work, and can direct research studies in new directions. These topics are important to my study but also introduce further discussion in regard to ethnographic research methods, current teacher praxis, and the continual development of cogenerative dialogue praxis.

abstract: The purpose of this action research study was to examine the impact of cogenerative dialogues on instructor and student perceptions of rigor in a master's and certification program for alternatively certified teachers. Additionally, the study was designed to determine if these open dialogues would impact instructional decisions of college instructors in the program. The investigator used a mixed methods research model that included surveys, interviews, and video of the dialogues to measure the impact. The results of the study indicated that both sets of participants remained consistent in their identification and definition of the term rigor. The cogenerative dialogues did have an impact on instructor understanding of student definitions of rigor. Instructors began to change some instructional decisions as a result of the dialogues in small groups. / Dissertation/Thesis / Ed.D. Educational Leadership and Policy Studies 2012
