Retextualização da escrita por alunos com surdez usuários da LIBRAS: em foco a mediação do professor

The way teachers will coordinate the writing appropriation process assumes an especial importance, sharing their knowledge with the deaf student, assigning importance and meaning for what this student was capable to produce, even if his production isn’t resembled to the idealized pattern of an adult writing. This study is proposed to investigate the mediation in rewriting activities, along with deaf students, held by eight trainee students of a Pedagogy course, with ages between 20 and 28 years old. Thereunto, this activities were recorded on video, for later transcription and descriptive analysis, subsided by a new model proposed in the literature. The results indicate: the importance of the rewriting in the understanding of write contents produce by deaf students, the participants’ attitudinal change about their role like coordinator and interlocutor in such activities and the greater teacher’s comprehension about notational and discursive aspects involved in the deaf student write production. These results allowed to conclude the future teachers’ need that will work in inclusive classes or in multifunctional classes, understand and use rewriting activities in their daily pedagogical practice for the appropriation for the promotion of the Portuguese write by the deaf student, user of LIBRAS. It should be noted these teachers’ need to know the LIBRAS’ grammar and have access to linguistic knowledge enabling them to comprehend the nature of the occurrences present in the texts produced by deaf students.

Legendagem e dublagem: diferenças na tradução do humor

This work aims on an approach concerning on Translation Theories, as well as the translational difficulties, the linguistic barriers with which the translator must know how to deal, the role of the translator as a conscious subject of his work while creating new texts and producing meanings. We will develop a discussion focused on the audiovisual translation practice which means the translation for subtitles and dubbings. It will be shown the translation process on both modalities and also the issue about the translation of humor in each of them, as the translator must use his translational skill, cultural and linguistic knowledge and creativity, not only to circumvent the rules imposed by the audiovisual translation market, but also to be able to create a new language for each character presented in the original material, so that the translation in Portuguese language may contain proper traces of humor from the Brazilian culture. Our main goal is an attempt to explain the reason for so many questions from the public who does not know the rules in the market for subtitling and dubbing translation and sometimes criticize the work of the translator if they realize any ‘loss of information’ or ‘a translation very poorly done’. Theories and arguments which prove that no translation is done badly, but it goes through recreations and modifications whenever it is necessary will be presented. By the explanation of this translation process, citation of translators who work in this area telling about their experiences and selected examples of translations from the ‘Everybody hates Chris’ sitcom, we hope to reflect and clarify such doubts.

Breve análise discursiva em três dicionários de fraseologia

In the current context of Metalexicography several types of studies have been conducted in order to better understand the organization of existing dictionaries and, thus, constitute a knowledge base that would support the development of new works. Regarding specifically the dictionaries of Phraseology, although there are many researchers who engage in this domain, there is still much to study in order to optimize and boost production as much monolingual as bilingual works. The aim of this paper is to present a brief discursive analysis of three phraseological dictionaries considering the pedagogical aspect.

Review of The Biology of Freshwater Wetlands: Biology of Habitats by Arnold G. van der Valko

Wetland ecology is a relatively new field that developed from an initial interest in a few direct benefits that wetlands provide to society. Consequently, much early scientific work was stimulated by economic returns from specific wetland services, such as production of peat and provision of habitat for economically valuable wildlife (e.g., waterfowl and furbearers). Over time, societal interest in wetlands broadened, and these unique habitats are now valued for many additional services, including some that bear non market value. Common examples include carbon sequestration, flood reduction, water purification, and aesthetics. The increased recognition of the importance of wetlands has generated a diversity of job opportunities in wetland ecology and management. Despite the increased knowledge base and enhanced job market, I am not aware of any institutions that offer specialty degrees in this new discipline. Indeed, relatively few institutions offer specific wetland ecology classes, with Arnold G. van der Valk and a few of his peers at other universities being notable exceptions.

Study of Micro Rotary Ultrasonic Machining

Product miniaturization for applications in fields such as biotechnology, medical devices, aerospace, optics and communications has made the advancement of micromachining techniques essential. Machining of hard and brittle materials such as ceramics, glass and silicon is a formidable task. Rotary ultrasonic machining (RUM) is capable of machining these materials. RUM is a hybrid machining process which combines the mechanism of material removal of conventional grinding and ultrasonic machining. Downscaling of RUM for micro scale machining is essential to generate miniature features or parts from hard and brittle materials. The goal of this thesis is to conduct a feasibility study and to develop a knowledge base for micro rotary ultrasonic machining (MRUM). Positive outcome of the feasibility study led to a comprehensive investigation on the effect of process parameters. The effect of spindle speed, grit size, vibration amplitude, tool geometry, static load and coolant on the material removal rate (MRR) of MRUM was studied. In general, MRR was found to increase with increase in spindle speed, vibration amplitude and static load. MRR was also noted to depend upon the abrasive grit size and tool geometry. The behavior of the cutting forces was modeled using time series analysis. Being a vibration assisted machining process, heat generation in MRUM is low which is essential for bone machining. Capability of MRUM process for machining bone tissue was investigated. Finally, to estimate the MRR a predictive model was proposed. The experimental and the theoretical results exhibited a matching trend.

Complex networks analysis of language complexity

Methods from statistical physics, such as those involving complex networks, have been increasingly used in the quantitative analysis of linguistic phenomena. In this paper, we represented pieces of text with different levels of simplification in co-occurrence networks and found that topological regularity correlated negatively with textual complexity. Furthermore, in less complex texts the distance between concepts, represented as nodes, tended to decrease. The complex networks metrics were treated with multivariate pattern recognition techniques, which allowed us to distinguish between original texts and their simplified versions. For each original text, two simplified versions were generated manually with increasing number of simplification operations. As expected, distinction was easier for the strongly simplified versions, where the most relevant metrics were node strength, shortest paths and diversity. Also, the discrimination of complex texts was improved with higher hierarchical network metrics, thus pointing to the usefulness of considering wider contexts around the concepts. Though the accuracy rate in the distinction was not as high as in methods using deep linguistic knowledge, the complex network approach is still useful for a rapid screening of texts whenever assessing complexity is essential to guarantee accessibility to readers with limited reading ability.

Extractive summarization using complex networks and syntactic dependency

The realization that statistical physics methods can be applied to analyze written texts represented as complex networks has led to several developments in natural language processing, including automatic summarization and evaluation of machine translation. Most importantly, so far only a few metrics of complex networks have been used and therefore there is ample opportunity to enhance the statistics-based methods as new measures of network topology and dynamics are created. In this paper, we employ for the first time the metrics betweenness, vulnerability and diversity to analyze written texts in Brazilian Portuguese. Using strategies based on diversity metrics, a better performance in automatic summarization is achieved in comparison to previous work employing complex networks. With an optimized method the Rouge score (an automatic evaluation method used in summarization) was 0.5089, which is the best value ever achieved for an extractive summarizer with statistical methods based on complex networks for Brazilian Portuguese. Furthermore, the diversity metric can detect keywords with high precision, which is why we believe it is suitable to produce good summaries. It is also shown that incorporating linguistic knowledge through a syntactic parser does enhance the performance of the automatic summarizers, as expected, but the increase in the Rouge score is only minor. These results reinforce the suitability of complex network methods for improving automatic summarizers in particular, and treating text in general. (C) 2011 Elsevier B.V. All rights reserved.

Directions for advancing the study of work transitions in the 21st century

Objectives: The purpose of this article is to share the details, outcomes and deliverables from an international workshop on work transitions in London, Ontario, Canada. Participants: Researchers, graduate students, and community group members met to identity ways to advance the knowledge base of strategies to enhance work participation for those in the most disadvantaged groups within society. Methods: A participatory approach was used in this workshop with presentations by researchers and graduate students. This approach included dialogue and discussion with community members. In addition, small group dialogue and debate, world cafe discussions, written summaries of group discussion and reflection boards were used to bring new ideas to the discussion and to build upon what we know. Findings: Two research imperatives and six research recommendations were identified to advance global dialogue on work transitions and to advance the knowledge base. Occupational justice can be used to support future research directions in the study of work transitions. Conclusions: Moving forward requires a commitment of community of researchers, clinicians and stakeholders to address work disparities and implement solutions to promote participation in work.

Query rewriting in information retrieval: automatic context extraction from local user documents to improve query results

The central objective of research in Information Retrieval (IR) is to discover new techniques to retrieve relevant information in order to satisfy an Information Need. The Information Need is satisfied when relevant information can be provided to the user. In IR, relevance is a fundamental concept which has changed over time, from popular to personal, i.e., what was considered relevant before was information for the whole population, but what is considered relevant now is specific information for each user. Hence, there is a need to connect the behavior of the system to the condition of a particular person and his social context; thereby an interdisciplinary sector called Human-Centered Computing was born. For the modern search engine, the information extracted for the individual user is crucial. According to the Personalized Search (PS), two different techniques are necessary to personalize a search: contextualization (interconnected conditions that occur in an activity), and individualization (characteristics that distinguish an individual). This movement of focus to the individual's need undermines the rigid linearity of the classical model overtaken the ``berry picking'' model which explains that the terms change thanks to the informational feedback received from the search activity introducing the concept of evolution of search terms. The development of Information Foraging theory, which observed the correlations between animal foraging and human information foraging, also contributed to this transformation through attempts to optimize the cost-benefit ratio. This thesis arose from the need to satisfy human individuality when searching for information, and it develops a synergistic collaboration between the frontiers of technological innovation and the recent advances in IR. The search method developed exploits what is relevant for the user by changing radically the way in which an Information Need is expressed, because now it is expressed through the generation of the query and its own context. As a matter of fact the method was born under the pretense to improve the quality of search by rewriting the query based on the contexts automatically generated from a local knowledge base. Furthermore, the idea of optimizing each IR system has led to develop it as a middleware of interaction between the user and the IR system. Thereby the system has just two possible actions: rewriting the query, and reordering the result. Equivalent actions to the approach was described from the PS that generally exploits information derived from analysis of user behavior, while the proposed approach exploits knowledge provided by the user. The thesis went further to generate a novel method for an assessment procedure, according to the "Cranfield paradigm", in order to evaluate this type of IR systems. The results achieved are interesting considering both the effectiveness achieved and the innovative approach undertaken together with the several applications inspired using a local knowledge base.

Social inclusion of vulnerable groups through participatory and emancipatory approaches. Implementing active citizenship and socially innovative actions in the framework of civil & human rights model of disability

The research hypothesis of the thesis is that “an open participation in the co-creation of the services and environments, makes life easier for vulnerable groups”; assuming that the participatory and emancipatory approaches are processes of possible actions and changes aimed at facilitating people’s lives. The adoption of these approaches is put forward as the common denominator of social innovative practices that supporting inclusive processes allow a shift from a medical model to a civil and human rights approach to disability. The theoretical basis of this assumption finds support in many principles of Inclusive Education and the main focus of the hypothesis of research is on participation and emancipation as approaches aimed at facing emerging and existing problems related to inclusion. The framework of reference for the research is represented by the perspectives adopted by several international documents concerning policies and interventions to promote and support the leadership and participation of vulnerable groups. In the first part an in-depth analysis of the main academic publications on the central themes of the thesis has been carried out. After investigating the framework of reference, the analysis focuses on the main tools of participatory and emancipatory approaches, which are able to connect with the concepts of active citizenship and social innovation. In the second part two case studies concerning participatory and emancipatory approaches in the areas of concern are presented and analyzed as example of the improvement of inclusion, through the involvement and participation of persons with disability. The research has been developed using a holistic and interdisciplinary approach, aimed at providing a knowledge-base that fosters a shift from a situation of passivity and care towards a new scenario based on the person’s commitment in the elaboration of his/her own project of life.

No(i)rthern Ireland: Crime fiction and the northern-irish scene. Proposed translation into italian of two short stories from "belfast noir"

The present thesis aims at proving the importance of cultural and literary contexts in the practice of translation: I shall show that, in the case of Northern Irish crime fiction, knowledge of both Northern Irish history and culture as well as of the genre of crime fiction are essential prerequisites for the production of a “responsible” translation. I will therefore offer a brief overview of the history of crime and detective fiction and its main subgenres; some of the most important authors and works will be presented as well, in an analysis that goes from the early years of the genre to the second half of the 20th century. I will then move the focus to Northern Ireland, its culture and its history, and particular attention will be paid to fiction writing in Ireland and Northern Ireland, with a focus on the peculiar phenomenon of “Troubles Trash”. I will tackle the topic of Northern Irish literature and present the contemporary scene of Northern Irish crime fiction; the volume from which the texts for the translation have been taken will be presented, namely Belfast Noir. Subsequently the focus will move on the theoretical framework within which the translations were produced: I will present a literary review of the most significative developments in Translation Studies, with particular attention to the “cultural turn” that has characterised this subject since the 1960s. I will then highlight the phenomenon of “realia” in translation and analyse the approaches of different scholars to the translation of culture-bound references. The final part represents the culmination and practical application of all that was presented in the previous sections: I will discuss the translation of culture-bound references according to the strategies presented in Chapter 4, referring to the proposed translations of two stories. Such analysis aims to show that not only expert linguistic knowledge, but also cultural awareness and a wide literary background are needed in order to make conscious choices in translation.

Über die Bedeutsamkeit linguistischen Wissens im privatwirtschaftlichen Arbeitsfeld

Until today, linguistics as an academic field does not aim at responding to the expectations of the job market. However, on the backdrop of an increasing interrelation of politics, economy and science, questions as to the applicability of linguistics to labour processes and the employability of linguists are raised and need to be answered. In analysing data gained in the course of 21 interviews conducted with linguists working in the private sector of economy, several issues have shown to be of major interest. This paper addresses firstly in what ways linguistics was likely to be seen as relevant for the jobs held by the various interviewees from the point of view of their employers, which is then compared to the interviewees' own evaluations on the relevance of linguistic knowledge for their daily work. On the one hand it becomes clear that there are differences between the three comparable situations in which the analysed transfer of knowledge takes place (Quereinstieg, Schnittstellenjob, "sprachperformativer Job"). One the other hand linguistic expertise in the extra-academic field seems to be most salient or approved of when it comes to language competence in text production or communicative situations, which further complicates the attempt to make linguistics transparent for non-linguists.

Overview of literature and information on "khat-related" mortality: a call for recognition of the issue and further research

During the past 20 years or so, more has become known about the properties of khat, its pharmacology, physiological and psychological effects on humans. However, at the same time its reputation of social and recreational use in traditional contexts has hindered the dissemination of knowledge about its detrimental effects in terms of mortality. This paper focuses on this particular deficit and adds to the knowledge-base by reviewing the scant literature that does exist on mortality associated with the trade and use of khat. We sought all peer-reviewed papers relating to deaths associated with khat. From an initial list of 111, we identified 15 items meeting our selection criteria. Examination of these revealed 61 further relevant items. These were supplemented with published reports, newspaper and other media reports. A conceptual framework was then developed for classifying mortality associated with each stage of the plant's journey from its cultivation, transportation, consumption, to its effects on the human body. The model is demonstrated with concrete examples drawn from the above sources. These highlight a number of issues for which more substantive statistical data are needed, including population-based studies of the physiological and psychological determinants of khat-related fatalities. Khat-consuming communities, and health professionals charged with their care should be more aware of the physiological and psychological effects of khat, together with the risks for morbidity and mortality associated with its use. There is also a need for information to be collected at international and national levels on other causes of death associated with khat cultivation, transportation, and trade. Both these dimensions need to be understood.
