Code pattern analysis of object-oriented programming languages

Code patterns, including programming patterns and design patterns, are good references for programming language feature improvement and software re-engineering. However, to our knowledge, no existing research has attempted to detect code patterns based on code clone detection technology. In this study, we build upon the previous work and propose to detect and analyze code patterns from a collection of open source projects using NiPAT technology. Because design patterns are most closely associated with object-oriented languages, we choose Java and Python projects to conduct our study. The tool we use for detecting patterns is NiPAT, a pattern detecting tool originally developed for the TXL programming language based on the NiCad clone detector. We extend NiPAT for the Java and Python programming languages. Then, we try to identify all the patterns from the pattern report and classify them into several different categories. In the end of the study, we analyze all the patterns and compare the differences between Java and Python patterns.

When do dialects become languages? A cognitive perspective

Several definitions exist that offer to identify the boundaries between languages and dialects, yet these distinctions are inconsistent and are often as political as they are linguistic (Chambers & Trudgill, 1998). A different perspective is offered in this thesis, by investigating how closely related linguistic varieties are represented in the brain and whether they engender similar cognitive effects as is often reported for bilingual speakers of recognised independent languages, based on the principles of Green’s (1998) model of bilingual language control. Study 1 investigated whether bidialectal speakers exhibit similar benefits in non-linguistic inhibitory control as a result of the maintenance and use of two dialects, as has been proposed for bilinguals who regularly employ inhibitory control mechanisms, in order to suppress one language while speaking the other. The results revealed virtually identical performance across all monolingual, bidialectal and bilingual participant groups, thereby not just failing to find a cognitive control advantage in bidialectal speakers over monodialectals/monolinguals, but also in bilinguals; adding to a growing body of evidence which challenges this bilingual advantage in non-linguistic inhibitory control. Study 2 investigated the cognitive representation of dialects using an adaptation of a Language Switching Paradigm to determine if the effort required to switch between dialects is similar to the effort required to switch between languages. The results closely replicated what is typically shown for bilinguals: Bidialectal speakers exhibited a symmetrical switch cost like balanced bilinguals while monodialectal speakers, who were taught to use the dialect words before the experiment, showed the asymmetrical switch cost typically displayed by second language learners. These findings augment Green’s (1998) model by suggesting that words from different dialects are also tagged in the mental lexicon, just like words from different languages, and as a consequence, it takes cognitive effort to switch between these mental settings. Study 3 explored an additional explanation for language switching costs by investigating whether changes in articulatory settings when switching between different linguistic varieties could - at least in part – be responsible for these previously reported switching costs. Using a paradigm which required participants to switch between using different articulatory settings, e.g. glottal stops/aspirated /t/ and whispers/normal phonation, the results also demonstrated the presence of switch costs, suggesting that switching between linguistic varieties has a motor task-switching component which is independent of representations in the mental lexicon. Finally, Study 4 investigated how much exposure is needed to be able to distinguish between different varieties using two novel language categorisation tasks which compared German vs Russian cognates, and Standard Scottish English vs Dundonian Scots cognates. The results showed that even a small amount of exposure (i.e. a couple of days’ worth) is required to enable listeners to distinguish between different languages, dialects or accents based on general phonetic and phonological characteristics, suggesting that the general sound template of a language variety can be represented before exact lexical representations have been formed. Overall, these results show that bidialectal use of typologically closely related linguistic varieties employs similar cognitive mechanisms as bilingual language use. This thesis is the first to explore the cognitive representations and mechanisms that underpin the use of typologically closely related varieties. It offers a few novel insights and serves as the starting point for a research agenda that can yield a more fine-grained understanding of the cognitive mechanisms that may operate when speakers use closely related varieties. In doing so, it urges caution when making assumptions about differences in the mechanisms used by individuals commonly categorised as monolinguals, to avoid potentially confounding any comparisons made with bilinguals.

Term Morphologies as Meaningful Typology Characteristics for Indexing Languages

Every indexing language is made up of terms. Those terms have morphological characteristics. These include terms made up of single words, two words, or more. We can also take into account the total number of terms.We can assemble these measures, normalize them, and then cluster indexing languages based on this common set of measures [1].Cluster analysis reviews discrete groups based on term morphology that comport with traditional design assumptions that separate ontologies, from thesauri, and folksonomies.

Diachronic and Synchronic Indexing: Modeling Conceptual Change in Indexing Languages

This paper outlines a model of conceptual change in indexing languages. Findings from this modeling effort point to three ways meaning and relationships are established and then change in an indexing language. These ways: structural, terminological, and textual point to ways indexing language metadata can aid in managing conceptual change in indexing languages.

Evidence of Term-Structure Differences among Folksonomies and Controlled Indexing Languages

With the advent of Internet-based technologies for information organization, many groups have constructed their own indexing languages. Biologists, Library and Information Science practitioners, and now social taggers have worked together to create large and many times complex indexing languages. In this environment of diversity, two questions surface: (1) what are the measurable characteristics of these indexing languages, and (2) do measurements of these indexing languages speciate along these characteristics? This poster presents data from this exploratory work.

Dialogues and senses produced in/by the publicity discourse of institutes of languages

This article aims at analyzing the dialogues between the publicity discourse from languages institutes, with their publicity focused on the disclosure of English language courses, established between the student (subject), potential interlocutor of these publicities, trying to understand the meaning effects which can be produced and circulate socially through these dialogues. In order to do that, this study takes into consideration the theoretical confluences between the Bakhtin Circle and the discourse theory from Michel Pêcheux, especially,  those which concern the notions of dialogue and senses produced in and by the publicity discourse from languages institutes.

CULTURE AND LITERATURE IN FOREIGN LANGUAGES LEARNING

This brief article is an introduction to questions as multiculturalism, identity and prejudice, from a specific point of view: a reflection on the importance of didactics in foreign literature and culture, and the role of reading as a meaningful education form in the undergraduating study programs of "Letras Estrangeiras" in Brazil.

Academic Literacy: history of literacy and expectations about the writing practices of the Languages Course

In this article, I analyze the history of literacy of a student taking up the Languages Course from a private university in the city of São Paulo. Backed up by reflections from the theoretical field of the New Literacy Studies, I investigate how the student’s previous literacy history and her contact with speeches about writing had an impact on the development of expectations about the writing practices in the Languages course. To this end, I refer to stretches in a transcription from a semi-structured interview held in 2009, when the participant in the research was in the first semester of the course. The analysis undertaken herein aims to show that the understanding of the previous literacy history of the public entering university can collaborate so that the academic writing conventions and, in turn, those of the academic genres are not presented to the students as something part of the common sense, rather, as something which can be taught.    

Initial training of Portuguese teachers for Speakers of Other Languages at UTFPR-CT: integrating theory and classroom practice

The purpose of this article is to analyze the initial training of foreign language teachers within an extension project, whose goal is to promote teaching Portuguese for Speakers of Other Languages ​​(PFOL) in the Federal  University of Technology- Paraná ( UTFPR), Curitiba Campus. Thus, a brief history about the activities developed in the program  will be presented as well as its relevance within the university. Also, an analysis of the program and its current status within the Language and Literature undergraduate course - UTFPR will be discussed. Finally, concepts of reflective teaching  (Perrenoud, 2002) and  teaching based on the indissociation between practice and theory (GIMENEZ, 2005) will be brought up.

A HISTORY OF PORTUGUESE LANGUAGE TEACHING MANUALS IN BRAZIL, IN THEIR VARIOUS LANGUAGES

This article aims to study the historical constitution of Portuguese Language Teaching Manuals in Brazil (PLT) in Brazil. To do this, we offer firstly an overview view of research on these Teaching Manuals as used in schools and in Portuguese language classes throughout the whole time they have existed. From this extensive period we draw attention to some historical perspectives that have decisively changed the direction of PLT, its classes and the day to day life in schools. From these we shall single out the public policies regarding quality pertaining to the National Program for Teaching Manuals (NPTM) and to the National Program for Teaching Manuals for High Schools, specifically and for 2015 (NPTMHS 2015). We seek theoretical support in: Comenius (1954), Oliveira et al. (1984), Soares (1986, 1998, 2001), Bittencourt (1993), Freitag et al. (1993), Munakata (1997), Coracini (1999), Batista (2001, 2003, 2004), Batista and Costa Val (2004), Bunzen (2001, 2005, 2009), Bunzen and Rojo (2008) Rojo and Batista (2008), among others. The result of this research will give a history of PLT made up of diverse social and political factors, as well as those continually arising.

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.
