EFFECTIVE FUNCTION CHOICE IN THE R SCRIPTING LANGUAGE

This project examines the current available work on the explicit and implicit parallelization of the R scripting language and reports on experimental findings for the development of a model for predicting effective points for automatic parallelization to be performed, based upon input data sizes and function complexity. After finding or creating a series of custom benchmarks, an interval based on data size and time complexity where replacement becomes a viable option was found; specifically between O(N) and O(N3) exclusive. As data size increases, the benefits of parallel processing become more apparent and a point is reached where those benefits outweigh the costs in memory transfer time. Based on our observations, this point can be predicted with a fair amount of accuracy using regression on a sample of approximately ten data sizes spread evenly between a system determined minimum and maximum size.

A virtual agent to sustaining children's engagement in language learning

In this thesis we aimed to explore the potential of gamification - defined as “the use of game elements in non-game contexts” [30] - in increasing children's (aged 5 to 6) engagement with the task. This is mainly due to the fact that our world is living a technological era, and videogames are an example of this engagement by being able to maintain children’s (and adults) engagement for hours straight. For the purpose of limiting complexity, we only addressed the feedback element by introducing it with an anthropomorphic virtual agent (human-like aspect), because research shows that virtual agents (VA’s) can influence behavioural change [17], or even induce emotions on humans both through the use of feedback provided and their facial expressions, which can interpreted in the same way as of humans’ [2]. By pairing the VA with the gamification concept, we wanted to 1) create a VA that is likely to be well-received by children (appearance and behaviour), and 2) have the immediate feedback that games have, so we can give children an assessment of their actions in real-time, as opposed to waiting for feedback from someone (traditional teaching), and with this give students more chances to succeed [32, 43]. Our final system consisted on a virtual environment, where children formed words that corresponded to a given image. In order to measure the impact that the VA had on engagement, the system was developed in two versions: one version of the system was limited to provide a simple feedback environment, where the VA provided feedback, by responding with simple phrases (i.e. “correct” or “incorrect”); for the second version, the VA had a more complex approach where it tried to encourage children to complete the word – a motivational feedback - even when they weren’t succeeding. Lastly we conducted a field study with two groups of children, where one group tested the version with the simple feedback, and the other group tested the ‘motivational’ version of the system. We used a quantitative approach to analyze the collected data that measured the engagement, based on the number of tasks (words) completed and time spent with system. The results of the evaluation showed that the use of motivational feedback may carry a positive effect on engaging children.

The theory of complexity adapted to international relations: the behaviour of the visegrad-ukraine complex adaptive system since November 2013

La teoría de la complejidad, propia del estudio de fenómenos relativos a las ciencias naturales, se muestra como un marco alternativo para comprender los eventos emergentes que surgen en el sistema internacional. Esta monografía correlaciona el lenguaje de la complejidad con las relaciones internacionales, enfocándose en la relación Visegrad—Ucrania, ya que ha sido escenario de una serie de eventos emergentes e inesperados desde las protestas civiles de noviembre de 2013 en Kiev. El sistema complejo que existe entre el Grupo Visegrad y Ucrania se ve , desde entonces, en la necesidad de adaptarse ante los recurrentes eventos emergentes y de auto organizarse. De ese modo, podrá comportarse en concordancia con escenarios impredecibles, particularmente en lo relacionado con sus interacciones energéticas y sus interconexiones políticas.

Thoughts on the development of writing on language settings contact

This scientific paper presents the results of an ethnographic study and it is aimed at reflect about the development of writing in language contexts in contact through reflective analysis of the interferences of speech in the writing production of children enrolled in the 7th grade of elementary school. The languages contexts in contact pay attention due to the complexity than the teaching of standard variety takes on linguistic diversity that enters the school. In this sense, we base this research on the theory Educational Sociolinguistic, based on authors: Bortoni-Ricardo (2004, 2005 and 2011) and Damke (1988, 2009 and 2013). The results demonstrate that the marks of the languages in contact that are present in the writing, are regulars and depend on the linguistic contact of the speaker, blending with the linguistic variation of the Portuguese language, and what it allow create pedagogical intervention activities that consider specifics contexts writing.

The contradiction as a constitutive problem of the language: the resonances between Ducrot and Bakhtin

This paper seeks to problematize the contradiction as constitutive sense of the language, from the studies developed by Ducrot (1987) and Bakhtin/Voloshinov (2006). We asked ourselves to what extent it would be possible to control the clarity of expression of ideas, and how you can delete any problem that risks a logical and coherent organization of saying. In the case of this work, we want to ask which place the contradiction takes on as well as the relation that it establishes with the coherence and incoherence. From the analysis of sustained statements in concepts of the Argumentation Theory and the Polyphony, from the authors mentioned before, it was possible to establish a contrastive relation between the two perspectives of analysis, bearing in mind the proposed question. What allowed us to say the discourse’s senses cannot be limited to the materiality of the language and a methodology of textual logic does not account for countless possibilities of organizing a text – it is necessary to involve other forms of analysis, in a study that takes advantage of the internal structures as contribution of external determinants than mean jointly.  

USING SEMANTICS AS A WAY TO UNDERSTAND TEXTUAL GENRES

This paper examines the perception of the characteristics of a set of Textual Genres based on Linguistic Analysis, drawing on a Textual Linguistics investigation and offering Semantics considerations as support. This is an attempt to show how relevant semantic investigations are to extend a perception on the characteristics of Textual Genres, without excluding pragmatic and discourse elements. The texts analyzed in this study were taken from a questionnaire designed to assess freshman and senior university students from courses of Bachelor of Arts in Language, in terms of knowledge about different Textual Genres and their characteristics. The analyses focus on the semantic elements that act in respect of question and answer in the questionnaire, and which include: A Semantics-Pragmatics interface, the considerations of the propositional calculus, the theories of tense and aspect of verbal and semantic primitives. On these terms, it is set a relationship between the cognitive mechanisms that operate in the production and reception of texts and a look at the functions that organize semantic text processing. The main analysis in this paper will concern the interface of Textual Linguistics, from authors as Beaugrande and Dressler (1981) and Adam (2011), with Semantic investigations in terms of meaning processing.

MEMORIES AND TRAJECTORIES: IMPLICATIONS IN THE IDENTITY CONSTRUCTION OF THE PROFESSIONAL LANGUAGE

Teachers, as professionals, carry out an essential role in the process of the social change. For this purpose, the process of teachers’ formation are deserving highlighted in the research field of Applied Linguistics, aiming to enhance the work of language professionals. In this term, the current paper seeks to investigate the previous knowledge of the students of Letters Course at Unioeste, subjects of this study, about teaching career and professor’s identity constitution.  Simultaneously, it is discussed some implications between the educational trajectory and these students’ Professional choice, considering that it is found in the initial stage of this formative process. The adopted methodology consists of a qualitative approach from memorials, seeking to stand out the conceptions and representations of those subjects about constitution of the teacher. Among some characteristics that stand out in the narratives regarding teacher identity, are the complexity of teaching, like the profession, as well as the diverse teaching practices and 'transgressive'.

Academic review: a study of textual production of new students in the distance education

This article focuses on the difficulties encountered in text production students of the first phase of an undergraduate distance learning course at the Federal University of Santa Catarina with regard to working with the gender discourse academic review. The research question that drives this study is: In terms of social experiences with written language system, which factors are inferreds in the analysis of problems of adaptation to the visualized gender in textual production reviews in the academic sphere in the course of Portuguese Language distance? The study developed is anchored in theories of literacy based on Street (1984; 2003; 2009), Hamilton (2000), Barton and Hamilton (2004), among other authors who discuss the new studies of literacy through ethnographic perspectives; as well as the theories of genres of Bakhtin and his Circle (2003 [1952/53]). The results show problems (not) appropriate to the genre, both in terms of compositional configuration as in relation to the thematic content and style and signal distinctions between school and family literacy practices and academic literacy practices, demanding methodological resignifications in addressing gender in the academic sphere. The study contributes to the Applied Linguistics area paying attention to the need to undertake a teaching preparation (Halte, 2008) that includes the experiences of students and their weaknesses, so as to focus on them.

UNOBJECTIONABLE WOUNDS OF ILLUMINATED E.: ANALYSIS OF THE MONITORING BODY LANGUAGE IN “LUMPÉRICA”

The following work focuses on experimental writing of the Chilean Diamela Eltit, who published his first novel in 1983, during the military dictatorship of Pinochet. Through its "bold" text, Eltit achieved dictatorial circumvent censorship and began his career as a writer.  

Experiences with an Object-Oriented, Multi-Stage Language

Metaphor is a multi-stage programming language extension to an imperative, object-oriented language in the style of C# or Java. This paper discusses some issues we faced when applying multi-stage language design concepts to an imperative base language and run-time environment. The issues range from dealing with pervasive references and open code to garbage collection and implementing cross-stage persistence.

The Coming of Post-reflexive Society: Commodification and Language in Digital Capitalism

Language is a unique aspect of human communication because it can be used to discuss itself in its own terms. For this reason, human societies potentially have superior capacities of co-ordination, reflexive self-correction, and innovation than other animal, physical or cybernetic systems. However, this analysis also reveals that language is interconnected with the economically and technologically mediated social sphere and hence is vulnerable to abstraction, objectification, reification, and therefore ideology – all of which are antithetical to its reflexive function, whilst paradoxically being a fundamental part of it. In particular, in capitalism, language is increasingly commodified within the social domains created and affected by ubiquitous communication technologies. The advent of the so-called ‘knowledge economy’ implicates exchangeable forms of thought (language) as the fundamental commodities of this emerging system. The historical point at which a ‘knowledge economy’ emerges, then, is the critical point at which thought itself becomes a commodified ‘thing’, and language becomes its “objective” means of exchange. However, the processes by which such commodification and objectification occurs obscures the unique social relations within which these language commodities are produced. The latest economic phase of capitalism – the knowledge economy – and the obfuscating trajectory which accompanies it, we argue, is destroying the reflexive capacity of language particularly through the process of commodification. This can be seen in that the language practices that have emerged in conjunction with digital technologies are increasingly non-reflexive and therefore less capable of self-critical, conscious change.

On Ordinal VC-Dimension and Some Notions of Complexity

We generalize the classical notion of Vapnik–Chernovenkis (VC) dimension to ordinal VC-dimension, in the context of logical learning paradigms. Logical learning paradigms encompass the numerical learning paradigms commonly studied in Inductive Inference. A logical learning paradigm is defined as a set W of structures over some vocabulary, and a set D of first-order formulas that represent data. The sets of models of ϕ in W, where ϕ varies over D, generate a natural topology W over W. We show that if D is closed under boolean operators, then the notion of ordinal VC-dimension offers a perfect characterization for the problem of predicting the truth of the members of D in a member of W, with an ordinal bound on the number of mistakes. This shows that the notion of VC-dimension has a natural interpretation in Inductive Inference, when cast into a logical setting. We also study the relationships between predictive complexity, selective complexity—a variation on predictive complexity—and mind change complexity. The assumptions that D is closed under boolean operators and that W is compact often play a crucial role to establish connections between these concepts. We then consider a computable setting with effective versions of the complexity measures, and show that the equivalence between ordinal VC-dimension and predictive complexity fails. More precisely, we prove that the effective ordinal VC-dimension of a paradigm can be defined when all other effective notions of complexity are undefined. On a better note, when W is compact, all effective notions of complexity are defined, though they are not related as in the noncomputable version of the framework.
