Modular average case analysis: Language implementation and extension

Motivated by accurate average-case analysis, MOdular Quantitative Analysis (MOQA) is developed at the Centre for Efficiency Oriented Languages (CEOL). In essence, MOQA allows the programmer to determine the average running time of a broad class of programmes directly from the code in a (semi-)automated way. The MOQA approach has the property of randomness preservation which means that applying any operation to a random structure, results in an output isomorphic to one or more random structures, which is key to systematic timing. Based on original MOQA research, we discuss the design and implementation of a new domain specific scripting language based on randomness preserving operations and random structures. It is designed to facilitate compositional timing by systematically tracking the distributions of inputs and outputs. The notion of a labelled partial order (LPO) is the basic data type in the language. The programmer uses built-in MOQA operations together with restricted control flow statements to design MOQA programs. This MOQA language is formally specified both syntactically and semantically in this thesis. A practical language interpreter implementation is provided and discussed. By analysing new algorithms and data restructuring operations, we demonstrate the wide applicability of the MOQA approach. Also we extend MOQA theory to a number of other domains besides average-case analysis. We show the strong connection between MOQA and parallel computing, reversible computing and data entropy analysis.

Los métodos de enseñanza en ELE : el método comunicativo revisado

Cette étude se focalise sur la révision de l’approche communicative des manuels d’enseignement de l’espagnol comme langue étrangère (ELE) et, plus particulièrement, sur celle des manuels utilisés dans les institutions scolaires du Québec. D’un point de vue historique, les premières inquiétudes liées à l’enseignement et à l’acquisition de langues secondes sont apparues dans l’Antiquité. Pendant des siècles, l’enseignement fondé sur la répétition de structures a prédominé, mais une fois le Moyen Âge passé, d’autres avancées pédagogiques sont nées. Par exemple, au XVIIe siècle, des études sur la question, inspirées de penseurs comme Montaigne et Locke, ont révélé que l’apprentissage formel de la langue n’était pas utile et que les apprenants avaient besoin d’une motivation pour apprendre. Le XXe siècle a été caractérisé par le déploiement de propositions méthodologiques à utiliser dans l’enseignement de langues secondes, et c’est ainsi que des méthodes telles que Directe, Audio-linguistique, Apprentissage communautaire de la langue et Approche naturelle ont surgi. Au milieu du XXe siècle s’est développée en Europe une proposition basée sur les besoins communicatifs des étudiants et ce qui, au début, était connu comme l’approche notionnelle fonctionnelle a évolué et est devenu l’enseignement communicatif. Une telle approche concerne essentiellement l’usage de la langue et accorde moins d’importance aux connaissances linguistiques. Elle a pour objectif principal que l’étudiant-parlant développe des habiletés interprétatives et expressives de la langue objet. En nous appuyant sur un cadre théorique de l’enseignement des langues et en analysant les manuels Nuevo ELE, Prisma et Español en marcha (niveaux A1-B2), nous prétendons vérifier la présence de l’approche communicative dans ces manuels afin de pouvoir démontrer que dans les activités dites communicatives, il y a différentes applications possibles des méthodes traditionnelles de l’enseignement de langues secondes et que, par conséquent, l’approche communicative réunit plusieurs propositions qui proviennent d’autres méthodes. Mot-clés : Espagnol langue étrangère (ELE), approche communicative, analyse de manuels, Nuevo ELE, Prisma, Español en marcha.

La importancia del género gramatical en la enseñanza de español como lengua extranjera

Le présent travail est encadré dans le domaine de la linguistique appliquée de l'espagnol comme langue étrangère (ELE), et plus spécifiquement dans l'enseignement du genre grammatical en ELE. Notre intérêt en tant que enseignants c’est de pouvoir établir une méthode fiable selon les critères du Plan curricular de l'Institut Cervantès et la technique du consciousness-raising, ainsi que élaborer des activités destinées à l'enseignement du genre grammatical dans la classe d’ELE. L'enseignement d'ELE au Québec suit les mêmes méthodes qu'en Europe. En ce qui concerne l'enseignement du genre grammatical, les études consultées ratifient le manque d'instruction pertinente à propos du genre grammatical, ainsi que la difficulté dans la concordance même dans des niveaux avancés. Cependant, l'analyse de manuels d'ELE utilisés dans les diverses institutions de Montréal permet de conclure que ceux-ci ne suivent pas les règles établies par le Plan curricular en ce qui concerne l'enseignement du genre. Pour vérifier ces faits un travail de champ a été mis en place avec 84 étudiants et étudiantes de six institutions de Montréal pendant deux mois et deux semaines. Les résultats de la recherche et l'analyse d'erreurs nous montrent qu’il y a des problèmes avec le genre grammatical chez les étudiants de niveau intermédiaire et que les erreurs ne disparaissent pas avec les activités de renfort créées. Il est donc nécessaire d’adopter une méthode plus appropriée à l'apprentissage du genre grammatical dans une classe d’ELE et la présence du professeur pour la présenter. En effet, l'exécution d'activités créées n'est pas suffisant, car bien que les résultats montrent un léger progrès dans le cas du groupe B, ou d’expérience, en comparaison au groupe A, ou de control, on a constaté qu’une instruction formelle aurait entrainé un meilleur et plus complet apprentissage du genre grammatical dans le cas de nos étudiants; de là la nécessité d'établir une méthode fiable pour son enseignement.

Lenguaje y valor en los escritos de Augusto Salazar Bondy (1965 - 1970)

Se examinan los escritos axiológicos de Augusto Salazar Bondy producidos entre 1965 y 1970, en los que predomina el análisis del lenguaje como criterio epistemológico y metodológico. Se señala el aprovechamiento de la metodología analítica por parte del peruano, así como los aspectos en que se separa de la filosofía moral británica y del primer Wittgenstein. Se consideran los aportes en relación a la caracterización de la experiencia del valor, el sentido del lenguaje valorativo y la fundamentación de los valores. Se destaca, para concluir, la concepción de los valores como categorías del obrar y la historicidad de la experiencia valorativa.

Contextual text mining

With the dramatic growth of text information, there is an increasing need for powerful text mining systems that can automatically discover useful knowledge from text. Text is generally associated with all kinds of contextual information. Those contexts can be explicit, such as the time and the location where a blog article is written, and the author(s) of a biomedical publication, or implicit, such as the positive or negative sentiment that an author had when she wrote a product review; there may also be complex context such as the social network of the authors. Many applications require analysis of topic patterns over different contexts. For instance, analysis of search logs in the context of the user can reveal how we can improve the quality of a search engine by optimizing the search results according to particular users; analysis of customer reviews in the context of positive and negative sentiments can help the user summarize public opinions about a product; analysis of blogs or scientific publications in the context of a social network can facilitate discovery of more meaningful topical communities. Since context information significantly affects the choices of topics and language made by authors, in general, it is very important to incorporate it into analyzing and mining text data. In general, modeling the context in text, discovering contextual patterns of language units and topics from text, a general task which we refer to as Contextual Text Mining, has widespread applications in text mining. In this thesis, we provide a novel and systematic study of contextual text mining, which is a new paradigm of text mining treating context information as the ``first-class citizen.'' We formally define the problem of contextual text mining and its basic tasks, and propose a general framework for contextual text mining based on generative modeling of text. This conceptual framework provides general guidance on text mining problems with context information and can be instantiated into many real tasks, including the general problem of contextual topic analysis. We formally present a functional framework for contextual topic analysis, with a general contextual topic model and its various versions, which can effectively solve the text mining problems in a lot of real world applications. We further introduce general components of contextual topic analysis, by adding priors to contextual topic models to incorporate prior knowledge, regularizing contextual topic models with dependency structure of context, and postprocessing contextual patterns to extract refined patterns. The refinements on the general contextual topic model naturally lead to a variety of probabilistic models which incorporate different types of context and various assumptions and constraints. These special versions of the contextual topic model are proved effective in a variety of real applications involving topics and explicit contexts, implicit contexts, and complex contexts. We then introduce a postprocessing procedure for contextual patterns, by generating meaningful labels for multinomial context models. This method provides a general way to interpret text mining results for real users. By applying contextual text mining in the ``context'' of other text information management tasks, including ad hoc text retrieval and web search, we further prove the effectiveness of contextual text mining techniques in a quantitative way with large scale datasets. The framework of contextual text mining not only unifies many explorations of text analysis with context information, but also opens up many new possibilities for future research directions in text mining.

Governance and community capitals : understanding how governance has worked in three faith-based schools in the Western Highlands of Papua New Guinea

This thesis, titled Governance and Community Capitals, explores the kinds of practical processes that have made governance work in three faith-based schools in the Western Highlands of Papua New Guinea (PNG). To date, the nation of PNG has been unable to meet its stated educational goals; however, some faith-based primary schools have overcome educational challenges by changing their local governance systems. What constitutes good governance in developing countries and how it can be achieved in a PNG schooling context has received very little scholarly attention. In this study, the subject of governance is approached at the nexus between the administrative sciences and asset-based community development. In this space, the researcher provides an understanding of the contribution that community capitals have made to understandings of local forms of governance in the development context. However, by and large, conceptions of governance have a history of being positioned within a Euro-centric frame and very little, if anything is known about the naming of capitals by indigenous peoples. In this thesis, six indigenous community capitals are made visible, expanding the repertoire of extant capitals published to date. The capitals identified and named in this thesis are: Story, Wisdom, Action, Blessing, Name and Unity. In-depth insights into these capitals are provided and through the theoretical idea of performativity, the researcher advances an understanding of how the habitual enactment of the practical components of the capitals made governance work in this unique setting. The study draws from a grounded and appreciative methodology and is based on a case study design incorporating a three-stage cycle of investigation. The first stage tested the application of an assets-based method to documentary sources of data including most significant change stories, community mapping and visual diaries. In the second stage, a group process method relevant to a PNG context was developed and employed. The third stage involved building theory from case study evidence using content analysis, language and metaphorical speech acts as guides for complex analysis. The thesis demonstrates the contribution that indigenous community capitals can make to understanding local forms of governance and how PNG faith-based schools meet their local governance challenges.

Pattern-based analysis of EAI languages : the case of the business modelling language

Enterprise Application Integration (EAI) is a challenging area that is attracting growing attention from the software industry and the research community. A landscape of languages and techniques for EAI has emerged and is continuously being enriched with new proposals from different software vendors and coalitions. However, little or no effort has been dedicated to systematically evaluate and compare these languages and techniques. The work reported in this paper is a first step in this direction. It presents an in-depth analysis of a language, namely the Business Modeling Language, specifically developed for EAI. The framework used for this analysis is based on a number of workflow and communication patterns. This framework provides a basis for evaluating the advantages and drawbacks of EAI languages with respect to recurrent problems and situations.

The pedagogical, linguistic and content features of popular English language learning websites in China : a framework for analysis and design

As increasing numbers of Chinese language learners choose to learn English online (CNNIC, 2012), there is a need to investigate popular websites and their language learning designs. This paper reports on the first stage of a study that analysed the pedagogical, linguistic and content features of 25 Chinese English Language Learning (ELL) websites ranked according to their value and importance to users. The website ranking was undertaken using a system known as PageRank. The aim of the study was to identify the features characterising popular sites as opposed to those of less popular sites for the purpose of producing a framework for ELL website design in the Chinese context. The study found that a pedagogical focus with developmental instructional materials accommodating diverse proficiency levels was a major contributor to website popularity. Chinese language use for translations and teaching directives and intermediate level English for learning materials were also significant features. Content topics included Anglophone/Western and non-Anglophone/Eastern contexts. Overall, popular websites were distinguished by their mediation of access to and scaffolded support for ELL.

A meta-analysis of the correlation between heritage language and ethnic identity

The interaction between heritage language (HL) and ethnic identity has gained increasing scholarly attention over the past decades. Numerous quantitative studies have investigated and vindicated this interaction within certain contexts. Nevertheless, quantitative evidence on this interaction across contexts is absent to date. The current meta-analysis aims to make a contribution in this regard. By integrating relevant studies, this meta-analysis presents a powerful estimation of the reality in relation to the interaction between HL and ethnic identity. By virtue of certain retrieval strategies and selection criteria, the meta-analysis includes 43 data-sets emerging from 18 studies that have addressed the statistical correlation between the proficiency of HL and the sense of ethnic identity associated with different ethnic groups. When contrasted to one another, the results of these included studies are significantly different. However, when combined together, these studies point to a statistically significant moderate positive correlation between sense of ethnic identity and proficiency of HL across different ethnic groups. This result has a medium effect. The meta-analysis also inspires some methodological and theoretical discussions.

Digging into signs: Developing standard annotation practices for cross-linguistic, quantitative analysis of sign language data. Final Report.

For sign languages used by deaf communities, linguistic corpora have until recently been unavailable, due to the lack of a writing system and a written culture in these communities, and the very recent advent of digital video. Recent improvements in video and computer technology have now made larger sign language datasets possible; however, large sign language datasets that are fully machine-readable are still elusive. This is due to two challenges. 1. Inconsistencies that arise when signs are annotated by means of spoken/written language. 2. The fact that many parts of signed interaction are not necessarily fully composed of lexical signs (equivalent of words), instead consisting of constructions that are less conventionalised. As sign language corpus building progresses, the potential for some standards in annotation is beginning to emerge. But before this project, there were no attempts to standardise these practices across corpora, which is required to be able to compare data crosslinguistically. This project thus had the following aims: 1. To develop annotation standards for glosses (lexical/word level) 2. To test their reliability and validity 3. To improve current software tools that facilitate a reliable workflow Overall the project aimed not only to set a standard for the whole field of sign language studies throughout the world but also to make significant advances toward two of the world’s largest machine-readable datasets for sign languages – specifically the BSL Corpus (British Sign Language, http://bslcorpusproject.org) and the Corpus NGT (Sign Language of the Netherlands, http://www.ru.nl/corpusngt).

A Game-Theoreteic Analysis of Minority Language Use in Multilingual Societies

This chapter studies multilingual democratic societies with highly developed economies. These societies are assumed to have two languages with official status: language A, spoken by every individual, and language B, spoken by the bilingual minority. We emphasize that language rights are important, but the survival of the minority language B depends mainly on the actual use bilinguals make of B. The purpose of the present chapter is to study some of the factors affecting the bilingual speakers language choice behaviour. Our view is that languages with their speech communities compete for speakers just as fi rms compete for market share. Thus, the con ict among the minority languages in these societies does not take the rough expressions such as those studied in Desmet et al. (2012). Here the con flict is more subtle. We model highly plausible language choice situations by means of choice procedures and non-cooperative games, each with different types of information. We then study the determinants of the bilinguals ' strategic behaviour with regard to language. We observe that the bilinguals' use of B is shaped, essentially, by linguistic conventions and social norms that are developed in situations of language contact.
