The aim was to analyse the verb usage in Portuguese phrasal writing structure as the deaf Second Language in networks. Take as a guideline: How do the Deaf who have Brazilian sign language as First Language employ the verb in Portuguese writing in networks? To answer this question, we go first to theorists whose work deal with Brazilian sign language, Portuguese, Portuguese writing, Portuguese as Second Language, verb, networks, writings and deafness, highlighting authors as Almeida (2007), Bagno (2011), Felipe (2013), Peixoto (2004), Quadros (2004, 2006), Recuero (2011), Zeni (2010), among others who discuss about the theme. In the second place, we gathered together a group in the net WhatsApp of about 20 deaf users of Brazilian sign language as First Language. That group took part in ―daily chats‖ about ordinary subjects in the network WhatsApp. Those ―chats‖ written in Portuguese were picked up from the above mentioned network and established the research corpus that was analysed under the Phenomenology standard experienced in two moments: graphic idea analysis and nomothetics analysis (abstract and unrelated ideas. From those processes arose five different rates of analysis: Verb in the Infinitive, Auxiliar Followed by main Verb, Verb with Oral sign, Unfit Verb and Unfit Usage and Inflection Verb. The analysed results showed: the network WhatsApp is considered a tool to help the acquisition of Portuguese as Second language, the deaf acquire Portuguese language as Second Language when they use the web, having in their writing a suitable verb inflection to understand the sentence and in their writings in spoken Portuguese as oral signifying. Starting from the understanding\interpretation that the inflection and finding attitude brought us, we suggest new studies in order to make closer the relation between. Brazilian sign language as First Language and Portuguese as Second Language so that the deaf can establish an interactive linking more proficient in the society that has Portuguese as First Language. / O trabalho apresenta a análise da produção escrita em Língua Portuguesa como L2 desenvolvida por surdos usuários da Língua Brasileira de Sinais- LIBRAS como L1, nas redes sociais. O objetivo foi analisar o emprego do verbo na estrutura frasal do português escrito como segunda língua dos surdos usuários das redes sociais. Partimos da seguinte questão norteadora: De que modo os surdos que têm a LIBRAS como sua primeira língua empregam o verbo no português escrito nas redes sociais? Para responder à questão norteadora, recorremos, primeiramente, aos teóricos cujos trabalhos versavam sobre LIBRAS, língua portuguesa, português escrito, português como segunda língua, verbo, redes sociais, escrita e surdez, destacando-se autores como: Almeida (2007), Bagno (2011); Felipe (2013), Peixoto (2004), Quadros (2004, 2006), Recuero (2011), Zeni (2010), dentre outros teóricos que discutem o tema em destaque. Num segundo momento, realizamos a criação de um grupo na rede social WhatsApp composto por 20 (vinte) surdos usuários de LIBRAS como L1. Os componentes do grupo participavam de ―conversas diárias‖ sobre temas do cotidiano na rede social WhatsApp. Essas ―conversas‖, escritas em português, foram capturadas da referida rede social e constituíram o corpus da pesquisa, o qual foi analisado à luz da Fenomenologia, vivenciando dois momentos: o da análise ideográfica e o da análise nomotética. Nesse processo, emergiram das ―conversas‖ dos componentes do grupo 5 (cinco) categorias de análise: verbo no infinitivo, verbo auxiliar acompanhado de principal, verbo com marca de oralidade, verbo com emprego inadequado e verbo com flexão adequada. Os dados analisados revelam os seguintes resultados: a rede social WhatsApp é uma ferramenta a ser considerada para auxiliar na aquisição do português como L2; os surdos se apropriam do português como L2, quando usam a rede social da web, adquirindo na escrita uma flexão verbal adequada para a compreensão da sentença e se valendo, em seus escritos, até de registros próprios do português falado, como as marcas de oralidade. A partir da compreensão/interpretação que a atitude de reflexão e de desvelamento nos proporcionou, sugerimos novos estudos, no sentido de estreitar os laços entre a LIBRAS como L1 e o português como L2, para que o surdo possa estabelecer uma relação interativa mais proficiente na sociedade que tem o português como L1.

This tool focuses on a project definition process, and was modeled using the MAAEM methodology and the ONTORMAS ontology-driven tool, as well as by reusing the ONTOINFO and ONTOWUM ontologies, which describe software product families for the development of Information Retrieval and Filtering applications, respectively. PROPOST looks for providing resource optimization by supporting reuse of existing information systems as well as avoiding duplicity on project definition for the composition on the organization’s software portfolio. The tool was created not only as a contribution for solving a current problem related to redundancy on portfolio definition, as well as support for several activities related to portfolio management (select, prioritization and evaluation). The development of PROPOST provides references on how ontology-based development can help in the software development process. It also contributes as a case study for evaluating the MAAEM methodology and the ONTORMAS ontology used in modeling process, having provided several hints for their improvement. / Este trabalho apresenta a PROPOST (Project Portfolio Support Tool), uma ferramenta baseada em conhecimento, para suporte à Gestão de Portifólio de Projetos – um modelo de gestão em ascensão na atualidade.

Pesquisa do Estado do RJ - FAPERJ / Nitrogen is one of the nutrient elements most limiting for plant growth. Thus, increasing plant nitrogen usage efficiency (NUE) is an essential factor for sustainable agriculture, leading to an increased food production with less fertilizer input and less environment impact. NUE in plant involves the uptake and accumulation efficiency, and N use efficiency for grain production. Understanding the mechanisms regulating these processes is crucial for the improvement of NUE in crops. Therefore, is essential to comprehend plants response to different N regimes, mainly N limitation. The usage of plants or varieties with differences in nutrient use efficiency is another important factor to determine the main mechanisms involved in these processes. The objectives of this study were to evaluate N metabolism and expression of genes involved in N uptake and assimilitation of two rice varieties (Piau? and IAC-47), under different N supply conditions. The N metabolism was evaluated by quantification of nitrogen fractions in plant tissue and enzymatic activity, expression of genes that code for high and low affinity N transporters, and N assimilation enzymes. Two experiments were conducted: the first, to investigate the plants behavior when grown under high and low N supply; and the second to verify plants response to NO3 - resupply. The IAC-47 variety showed greatest mass accumulation in all treatments. When plants were grown for a long period under low N supply it was observed a higher nitrate (NO3 -) content in the tissue of Piau? variety, which is adapted to low fertility conditions, as well as a high activity of nitrate reductase and glutamine synthetase in the roots of these plants. When under high NO3 - supply for a long period, Piau? variety had higher NO3 - concentrations in roots and sheaths, but no differences were observed in enzymes activity. The nitrate transporters expression was higher in roots of Piau? plants under low supply of NO3 - when compared to Piau? plants under high N supply. Nitrate transporters expression in roots of IAC-47 plants showed a pattern opposite to the one observed for Piau? plants. When plants were resupplied with NO3 -, after a 72 hours period without N, there was a rapid increase, after 6 hours of resupply, in the expression of high affinity nitrate transporters genes (OsNRT2.1) and the plastidial glutamine synthetase (GS2) in the Piau? variety roots, and a higher expression of these in IAC-47 roots after a 24 hours of N resupply. The efficiency of Piau? variety is related to the differentiated control of N absorption and assimilation mechanisms, which allow bigger expression of high affinity nitrate transporters in tissue with high levels of soluble N, high N status, indicating that the control of nitrogen uptake system may be essential for the nitrogen usage efficient. / O nitrog?nio ? um dos elementos minerais que mais limita o desenvolvimento das plantas. Assim, aumentar a efici?ncia de uso de nitrog?nio (EUN) ? um fator ? essencial para uma agricultura sustent?vel, levando a um aumento da produ??o de alimentos com menor uso de insumos e menos impactos ao ambiente. A EUN envolve a efici?ncia de absor??o e ac?mulo e a efici?ncia de utiliza??o de N para produ??o. Compreender os mecanismos envolvidos nesses processos e como eles s?o controlados ? fundamental para a melhoria da EUN nas plantas cultivadas. Para isso, ? essencial entender a resposta e comportamento das plantas a diferentes regimes de N, principalmente ? limita??o de N. O uso de plantas ou variedades com diferen?as na EUN ? outro fator importante para verificar os principais mecanismos envolvidos. Este trabalho teve por objetivo desse trabalho foi verificar o metabolismo e a express?o de genes envolvidos na absor??o e assimila??o de nitrog?nio nas variedades de arroz Piau? e IAC-47 sob diferentes condi??es de disponibilidade desse nutriente. O metabolismo de N foi avaliado atrav?s da quantifica??o das fra??es nitrogenadas no tecido e atividade enzim?tica, a express?o de genes que codificam para transportadores de N de alta e baixa afinidade e enzimas de assimila??o de N. Foram realizados dois experimentos: o primeiro para verificar o comportamento das plantas quando cultivadas sob alto e baixo suprimento de N; e o segundo, para verificar as repostas ao ressuprimento de N. O ac?mulo de massa foi maior na variedade IAC-47 em todos os tratamentos. Quando as plantas foram cultivadas por um longo per?odo sob baixo suprimento de N foi observado maior teor de nitrato (NO3 -) no tecido da variedade Piau?, adaptada a condi??es de baixa fertilidade, assim como uma alta atividade da nitrato redutase e glutamina sintetase nas ra?zes dessas plantas. Sob alto suprimento de NO3 -, por um longo per?odo, a variedade Piau? apresentou maiores teores de NO3 - nas bainhas e ra?zes, mas n?o foram observas diferen?as na atividade de enzimas. A express?o dos transportadores de nitrato na variedade Piau? foi mais elevada nas ra?zes das plantas sob baixo suprimento de NO3 - quando comparado as plantas sob alto suprimento de N. Na variedade IAC-47 a express?o dos transportadores de NO3 - teve comportamento oposto ao observado para a Piau?. Quando as plantas receberam NO3 -, ap?s um per?odo de 72 horas sem N, houve um r?pido aumento, ap?s 6 horas do ressuprimento, na express?o do gene que codifica para o transportador de NO3 - de alta afinidade OsNRT2.1 e glutamina sintetase plastidial (GS2) nas ra?zes da variedade Piau?, e 24 horas ap?s o ressuprimento a express?o foi maior na variedade IAC-47. A efici?ncia da variedade Piau? esta relacionada ao controle diferenciado dos mecanismos de absor??o e assimila??o de N, que permite a maior express?o dos transportadores de nitrato de alta afinidade em tecido com altos teores de N sol?vel, alto status de N, indicando que o controle do sistema de absor??o de N pode ser essencial para a efici?ncia no uso de nitrog?nio.

Dans les trente prochaines années la génération du baby boom va atteindre le troisième âge et participer au vieillissement de la société. Cette population aura un besoin massif d’aide et de soins dont il n’est pas garanti que l’on puisse les assurer. Les nouvelles technologies adressées aux personnes âgées peuvent aider à résoudre ce problème mais pour cela il est indispensable que les aînés les acceptent. L’objectif de cette thèse est d’offrir un moyen de mesurer l’acceptation de ces technologies et de prédire leur utilisation. L’analyse de la documentation scientifique a permis d’identifier un modèle ayant les qualités requises pour cela, le modèle d’acceptation technologique proposé par Davis en 1989 (Technology Acceptance Model, TAM). Ce modèle se révèle parcimonieux et bien documenté mais il n’existait qu’en langue anglaise. D’autre part, la documentation scientifique montrait que la technologie la plus répandue parmi la population âgée et dépendante était la téléalarme. Ainsi, il a été décidé de traduire en français, adapter et valider un questionnaire issu du TAM pour prédire l’utilisation de la téléalarme par les personnes âgées dépendantes. Quatre études ont donc été menées, la première a consisté en une série d’entretiens, la deuxième en un questionnaire papier, et les deux dernières en un questionnaire par téléphone. Ce travail a abouti à l’obtention d’un instrument à dix items dont les qualités psychométriques se sont révélées acceptables. Le TAM fonctionne de la manière attendue il est donc possible de prédire l’utilisation de la téléalarme. Cependant deux limites doivent nuancer ces résultats, la première est que les études réalisées sont transversales ce qui empêche de parler de validité prédictive, la seconde et la modeste variance expliquée du questionnaire en français comparativement aux résultats publiés. En conclusion, le modèle doit s’enrichir de concepts spécifique à la population âgée afin d’affiner ses prédictions. / In the next thirty years the baby boomers are going to reach the third age and participate in the ageing of the whole French society. But no one can guarantee that their massive need of assistance and care will be provided. Information and communication technologies have the potential to help the elderly but only if they accept it. The aim of this thesis is to build a tool to assess the acceptance of these technologies and to predict their use. The scientific literature analysis revealed that the technology acceptance model proposed by Davis in 1989 had all the required qualities to build this tool. This model shows itself parsimonius and well documented but only existed in English. According to the literature the most widespread technology among the dependent elderly was the warning alarm. Thus, it was decided to translate into French, to adapt and to validate a questionnaire stemming from the technology acceptance model to predict the use of the warning alarm by dependent elderly. Four studies were thus led, the first consisted in a series of qualitative interviews, the second used a paper a pencil questionnaire, and both last ones in a phone questionnaire. This work ended in a ten items instrument with acceptable psychometric properties. The technology acceptance model works as expected and thus it is possible to predict the use of the remote alarm by dependent elderly. However, two shortcomings have to qualify these results, first the studies presented are cross-sectional which prevents from testing predictive validity, second the amount of explained variance by the questionnaire in French is limited compared with the published results. Finally, the model need to incorporate elderly specific constructs in order to make more accurate predictions.

The purpose of this study is to determine the type, possible source and gravity of errors found in the Test of Written English and Placement Tests compositions written by native speakers of Arabic at college level. The first part of the study is an error analysis designed to reveal the types of errors that are most frequently made by Arab students at college level. The sources of these errors are explained according to Richards' classification of errors as inter- and intralingual (1971). Seven types of errors are identified under interlingual category: articles, prepositions, the copula, embedded questions, pronoun retention, semantic and stylistic errors. Intralingual errors included errors in overgeneralization and ignorance of rule restriction.

Patient portals are web-based tools that provide patients with access to their health records and enhance communication with providers. Despite the efforts in expanding their use and patients interest in using them, patient portal usage remains low. Higher use of portals is associated with greater patient engagement and better healthcare quality and outcomes. This study investigated the impact of perceived usefulness (PU) and perceived ease of use (PEU) on patient portal usage. The conceptual framework was based on the Technology Acceptance Model, which suggests that PU and PEU of a system affect attitude and behavioral intention toward using the system, and ultimately the use of the system. The research questions focused on whether PU and PEU significantly affect portal usage. Participants included a convenience sample of 432 patients of Abington Health, located in Abington, PA, who had access to Abington's eClinicalWorks patient portal. Cross-sectional data collected from the completed online surveys included responses to Davis' PU and PEU measurement scale, self-reported portal login frequency and login duration, and some patient demographics. Data was analyzed by using chi-square test of independence and multinomial logistic regression. The study found that a significant relationship exists between PU and login frequency, PU and login duration, and PEU and login duration; however, the impact of PU and PEU on portal usage was not significant. The study could be repeated among a different population using a different patient portal. This study helps understand the relationship between PU/PEU and portal usage, something healthcare providers can capitalize upon when promoting portal use, and ultimately, encouraging greater patient engagement in their own health.

Thesis (MA. (Translation Studies and Linguistics)) -- University of Limpopo, 2013 / The study sought to investigate the challenges that the learners and educators encountered in learning and teaching when they use English as a medium of instruction. The study reveals that African languages, along with their culture are being dominated by English. Most of Pedis’ learners cannot speak Sepedi without mixing it with English, and most of African people usually read English books and neglecting the Indigenous books. In addition, the study shows that learners performed better when they were taught in Sepedi than in English. The educators’ responses showed that learners have difficulties in understanding English as the medium of instruction and that they code-switch from English to Sepedi to enhance understanding.

Dans un environnement économique à faible croissance et à forte concurrence, l'avance technologique est importante, mais très souvent ne suffit plus. Pour être compétitif, il convient aussi, de faire le bon produit, c'est-à dire le produit qui correspond aux réels besoins, attentes et caractéristiques des utilisateurs. Par conséquent, l'usage du produit devient une source d'innovation pour les entreprises industrielles. Pour intégrer l'usage d'un produit en conception, nous choisissons d'étudier les phases de convergence multidisciplinaire sur le couple produit/usage car ce sont des phases de collaboration forte entre les acteurs métiers tout au long du processus de conception. Les différentes disciplines, connaissances et pratiques impliquées dans les projets de conception, rendent le transfert des connaissances difficile entre les acteurs métiers durant ces phases. Face à cette problématique, nous nous intéressons plus particulièrement aux Objets Intermédiaires de Conception (OICs) (ex.prototype virtuel, maquette physique, etc.) comme moyen pour faciliter l'échange et la communication entre les acteurs métiers. Notre objectif est d'améliorer la collaboration entre les acteurs à travers l'étude des OICs et une meilleure compréhension des apports de ces objets. Dans nos travaux de thèse, nous indiquons l'intérêt de l'ajout d'interactions dédiées aux acteurs métier à l'OIC pour améliorer la qualité de la collaboration sur le couple produit/usage. Cela a été montré à travers le développement et la validation d'un outil d'annotation et sketching 2D (Virtusketches) en environnement virtuel immersif. Nos résultats montrent des différences significatives entre prototype virtuel (sur une plateforme de réalité virtuelle) et modèle CAO (sur un système CAO) concernant la qualité de collaboration et les objectifs des acteurs métier durant des revues de projets de conception. Nous proposons aussi une approche méthodologique DCDO (Démarche méthodologique de Choix et de Définition des OICs) pour le choix et la définition des OICs. L'une des originalités de cette approche réside dans le fait de considérer tous lesaspects liés à la définition de l'OIC dans le contexte de la convergence sur le couple produit/usage. Cette approche méthodologique a été implémentée et mise en pratique dans un module de revue de projet en environnement PLM(Product Lifecycle Management). / In our economic environment with low growth and high competition, technological advance is important, but often not enough. To be competitive, it is also necessary to propose a product which corresponds to the real needs, expectations and characteristics of users. Therefore, product use becomes a source of innovation by industrial companies. In order to integrate product use in design process, we choose to study the multidisciplinary convergence phases about the product and its related use because they are phases of strong collaboration between design actors. However, different disciplines, knowledge and practices involved in design projects, make the transfer of knowledge between design actors difficult. To this end, we are particularly interested in Intermediary Objects of Design (IOs) (ex. Virtual prototype, physical prototype, etc.) as a means to facilitate the exchange and communication between design actors. Our goal is to improve collaboration between design actors through the study of IOs, a better understanding of theirs contributions and the definition of a methodology that allows designactors to define these objects depending on their own needs and expectations. In this context, we indicate the interest of adding interactions dedicated to design actors through the IOs to improve the quality of collaboration. This has been shown through the developing and validating an annotation and 2D (Virtusketches) sketching tool in immersive virtual environment. Our results also show significant differences between a virtual prototype using (virtual reality platform) and CAD model (using CAD system) concerning the quality of collaboration and the realized objectives in design reviews. We also propose a methodological approach for the choice and the definition of IOs (DCDO). One of the originalities of this approach lies in the fact to consider all aspects related to the definition of the IOs in the context of convergence on the product/use couple. This methodological approach has been implemented and put into practice using an application to prepare project reviews in PLM (Product Lifecycle Management).environment.

Abstract not available

This case study explored the revision strategies of four Malaysian native speakers of English when they composed aloud while writing an argumentative essay. Think aloud verbal protocols were analysed using the grounded theory approach in conjunction with written texts. The findings suggest that contextual factors influenced classroom practices. The contextual factors included a teacher who was not provided with adequate training, administrative policies which did not provide support for the development of writers based on their abilities, writing instruction which viewed revision as a process of error correction and public assessment practices which were non-transparent. These classroom practices influenced the participants� beliefs about revision. These beliefs affected the quality of their essays as judged by Malaysian public examiners. Additionally, the findings suggest a mismatch between classroom instruction and public examination. Suggestions are made to address these concerns by considering the theoretical underpinnings of the cognitive process, socio-cultural and community of practice models of writing and learning. These include instruction on revision strategies, considering alternative assessment practices, providing formative feedback, ability streaming, focussing on critical reading skills and providing adequate support to the teacher.
