Marcadores da organização do padrão discursivo narrativo: uma abordagem funcional centrada no uso

This thesis has as its object the Markers Organization Standard Narrative Discourse (MON), from its occurrence in oral and written corpora of different realizations of narrative discourse, considering its locus of occurrence in the narrative and discursive functioning. The research is guided by the Functional Linguistic Usage-Based, approach to which the organization of language is directly linked to the user experience, so that grammar is shaped by discourse. We examined only the narrative portions of Experience Reports, Tales and Legends in the oral and written, as follows: 3 inquiries Corpus Reports Remaining Quilombo (RN); 11 Corpus Legends legends of the Amazon, 14 Tales of Corpus Tales Brazilians and 21 Reports of experiences of Corpus and Discourse Grammar, with about 10,000 words in each corpus. A total of 22 markers were identified, which were: (1) classified according to the locus of occurrence in the narrative structure, as Labov (1972), (2) associated, according to the type of pattern that occur in narrative discourse, (3) described from the discursive function they perform. The research has relevance to the extent it is based speech analysis and offers proposals for productive teaching of mother tongue in which students and teachers can, grounded in language studies, consider living language, as an object of study, based on the National Curriculum Guidelines (OCN) and making use of New Technologies of Information and Communication (NTIC)

AI, LA, ALI e AQUI: gramaticalização de um paradigma emergente no domínio funcional da especificação nominal

In the light of the Functional Linguistic Theory, in its North-American version (HOPPER, 1987, 1991, 1998, 2008, 2010; GIVÓN, 2001; LEHMANN, 2002; HOPPER; TRAUGOTT, 2003; FURTADO DA CUNHA; OLIVEIRA; MARTELOTTA, 2003, among others), the general objective of this research is to demonstrate, based on morphosyntactic and semantic-pragmatic properties, that AQUI (HERE), AÍ, ALI and LÁ (THERE) are part of an emerging paradigm in Brazilian Portuguese recently constituted and still developing of forms indicating specificity in indefinite noun phrases (NP). The data that make up the corpus of this research were collected in the following large Brazilian oral corpora: the Corpus Discurso & Gramática: a língua falada e escrita na cidade de Natal (FURTADO DA CUNHA, 1998), the Banco Conversacional de Natal (FURTADO DA CUNHA, 2010), the Projeto Variação Linguística no Estado da Paraíba VALPB (HORA, 2005) and the Projeto Variação Linguística Urbana na Região Sul do Brasil VARSUL (VANDRESEN, 2002). Firstly, the behavior of the specificity markings AQUI, AÍ, ALI and LÁ is described with respect to many factors of morphosyntactic and semantic-pragmatic nature: type of construction in which the markers appeared; existence or not of intervening material between the specificity marker item and the NP s nuclear noun; type of noun to which AQUI, AÍ, ALI and LÁ are linked; syntactic function of the specified SN; informational status of the NP to which the specificity markers AQUI, AÍ, ALI and LÁ are attached; occurrence of conversational implicatures (GRICE, 1982) in the context of use of these specificity markers. Next, a possible grammaticalization trajectory is outlined, according to which AQUI, AÍ, ALI and LÁ would had gone from an early spatial deictic indication to the specificity indication. The results point to the existence of forms with varying degree of emergence in this new paradigm of nominal specification, with AÍ being, probably, the item most grammaticalized, followed by LÁ, then ALI and AQUI, which permanence in the paradigm do not yet appear to be consolidated

LWiSSy: uma linguagem específica de domínio para modelagem de sistemas de redes de sensores e atuadores sem fio

The field of Wireless Sensor and Actuator Networks (WSAN) is fast increasing and has attracted the interest of both the research community and the industry because of several factors, such as the applicability of such networks in different application domains (aviation, civil engineering, medicine, and others). Moreover, advances in wireless communication and the reduction of hardware components size also contributed for a fast spread of these networks. However, there are still several challenges and open issues that need to be tackled in order to achieve the full potential of WSAN usage. The development of WSAN systems is one of the most relevant of these challenges considering the number of variables involved in this process. Currently, a broad range of WSAN platforms and low level programming languages are available to build WSAN systems. Thus, developers need to deal with details of different sensor platforms and low-level programming abstractions of sensor operational systems on one hand, and they also need to have specific (high level) knowledge about the distinct application domains, on the other hand. Therefore, in order to decouple the handling of these two different levels of knowledge, making easier the development process of WSAN systems, we propose LWiSSy (Domain Language for Wireless Sensor and Actuator Networks Systems), a domain specific language (DSL) for WSAN. The use of DSLs raises the abstraction level during the programming of systems and modularizes the system building in several steps. Thus, LWiSSy allows the domain experts to directly contribute in the development of WSANs without having knowledge on low level sensor platforms, and network experts to program sensor nodes to meet application requirements without having specific knowledge on the application domain. Additionally, LWiSSy enables the system decomposition in different levels of abstraction according to structural and behavioral features and granularities (network, node group and single node level programming)

POPT: uma abordagem de ensino de programação orientada a problema e testes

There is a growing interest of the Computer Science education community for including testing concepts on introductory programming courses. Aiming at contributing to this issue, we introduce POPT, a Problem-Oriented Programming and Testing approach for Introductory Programming Courses. POPT main goal is to improve the traditional method of teaching introductory programming that concentrates mainly on implementation and neglects testing. POPT extends POP (Problem Oriented Programing) methodology proposed on the PhD Thesis of Andrea Mendonça (UFCG). In both methodologies POPT and POP, students skills in dealing with ill-defined problems must be developed since the first programming courses. In POPT however, students are stimulated to clarify ill-defined problem specifications, guided by de definition of test cases (in a table-like manner). This paper presents POPT, and TestBoot a tool developed to support the methodology. In order to evaluate the approach a case study and a controlled experiment (which adopted the Latin Square design) were performed. In an Introductory Programming course of Computer Science and Software Engineering Graduation Programs at the Federal University of Rio Grande do Norte, Brazil. The study results have shown that, when compared to a Blind Testing approach, POPT stimulates the implementation of programs of better external quality the first program version submitted by POPT students passed in twice the number of test cases (professor-defined ones) when compared to non-POPT students. Moreover, POPT students submitted fewer program versions and spent more time to submit the first version to the automatic evaluation system, which lead us to think that POPT students are stimulated to think better about the solution they are implementing. The controlled experiment confirmed the influence of the proposed methodology on the quality of the code developed by POPT students

A correlação locução adjetiva/adjetivo: uma análise funcional

This research deals with the relationship locução adjetiva / adjective, focusing the reasons for using one form or the other one, in situations where the speaker has a choice between an adjective or a locução adjetiva virtually correspondent and vice versa. In general, the objective is to investigate the possibility of correlation between locução adjetiva and adjective, and to identify motivations for the use of one form or the other one. The theoretical support of this paper is the Linguística Funcional Centrada no Uso (LFCU), which groups together theoretical and methodological assumptions of North American Functional Linguistics, represented by authors as Givón (1984), Bybee (2010), Traugott (2011), and Cognitive Linguistics, as developed by Lakoff (1987), Langacker (1987) and Lakoff and Johnson (2002). As regards the methodological procedures, this research is of qualitative and quantitative character: at first, we did the survey data in the texts that made up the corpus, followed by analysis of each them, especially the locução adjetiva, by considering the semantic, morphosyntactic, cognitive and pragmatic aspects. The corpus is composed of 36 texts, taken from 12 issues of the Veja magazine, published between January 2013 and March 2013. As for the results, in the case of locução adjetiva with related adjectives, this research has shown that the choice of former is due to semantic change, the use of lexicalized forms, to priming cases or to stylistic motivations. It means that the choices of one of these two forms go beyond lexical issues, since there are other motivations, such as syntactic, semantic and pragmatic ones.

O slogan empresarial como construção discursiva: uma abordagem cognitivo-funcional

In this paper, we analyze corporate slogans, understanding them as a discursive construction that is, as a pairing of form and function able to unite the notions of textual type and discursive genre. In this way, we developed a qualitative and quantitative analysis, aimed specifically to analyze the formal properties (phonetic, morphological and syntactic) and functional (semantic, pragmatic and discursive) of slogans. Furthermore, we attempted at verifying and quantifying recurring aspects involved in their construction, in order to capture configurational patterns underlying their formation. The data come from slogans collected in products and / or service stores in the metropolitan area of Natal city, Rio Grande do Norte. This research is based on the Cognitive-Functional Linguistics, that conjugates the North American functionalist tradition, represented by researchers as Talmy Givón, Paul Hopper, Joan Bybee, Elizabeth Closs-Traugott, with Cognitive Linguistics, in particular, the chain linked to Construction Grammar, as postulated by Adele Goldberg, William Croft e Jan-Olla Östman, among others. The results ratified the importance of the interface between the formal and functional aspects in the analysis of linguistic uses. These results point to the idea of the slogan as the pairing of form and function on textual / discursive level, in other words, as a discursive construction, constituting as cognitive storage of a scheme / model of textual formation with a specific discursive-pragmatic function.

Ambiente para avaliação de controladores fuzzy aplicados ao método de elevação artificial por bombeio centrífugo submerso

From their early days, Electrical Submergible Pumping (ESP) units have excelled in lifting much greater liquid rates than most of the other types of artificial lift and developed by good performance in wells with high BSW, in onshore and offshore environments. For all artificial lift system, the lifetime and frequency of interventions are of paramount importance, given the high costs of rigs and equipment, plus the losses coming from a halt in production. In search of a better life of the system comes the need to work with the same efficiency and security within the limits of their equipment, this implies the need for periodic adjustments, monitoring and control. How is increasing the prospect of minimizing direct human actions, these adjustments should be made increasingly via automation. The automated system not only provides a longer life, but also greater control over the production of the well. The controller is the brain of most automation systems, it is inserted the logic and strategies in the work process in order to get you to work efficiently. So great is the importance of controlling for any automation system is expected that, with better understanding of ESP system and the development of research, many controllers will be proposed for this method of artificial lift. Once a controller is proposed, it must be tested and validated before they take it as efficient and functional. The use of a producing well or a test well could favor the completion of testing, but with the serious risk that flaws in the design of the controller were to cause damage to oil well equipment, many of them expensive. Given this reality, the main objective of the present work is to present an environment for evaluation of fuzzy controllers for wells equipped with ESP system, using a computer simulator representing a virtual oil well, a software design fuzzy controllers and a PLC. The use of the proposed environment will enable a reduction in time required for testing and adjustments to the controller and evaluated a rapid diagnosis of their efficiency and effectiveness. The control algorithms are implemented in both high-level language, through the controller design software, such as specific language for programming PLCs, Ladder Diagram language.

Caracterização funcional de dois cDNAs homólogos à ciclofilina e à proteína reprimida por auxina (ARP) identificados em bibliotecas subtrativas a para floração em tomateiro

Flowering is a fundamental process in the life cycle for plant. This process is marked by vegetative to reproductive apical meristem conversion, due to interactions between several factors, both internal and external to plant. Therefore, eight subtractive libraries were constructed using apical meristem induced or not induced for two contrasting species: Solanum lycopersicum cv. Micro-Tom and Solanum pimpinellifolium. Several cDNAs were identified and among these, were selected two cDNAs: one homologous cDNA to cyclophilin (LeCYP1) and the other to Auxin repressed protein (ARP). It has observed that LeCYP1 and ARP genes are important in the developmental process to plants. In silico analysis, were used several databases with the exclusion criterion E-value <1.0x10-15. As a result, conservation was observed for proteins analyzed by means of multiple alignments and the presence of functional domains. Then, overexpression cassettes were constructed for the ARP cDNA in sense and antisense orientations. For this step, it was used the CaMV35S promoter. The cDNA orientation (sense or antisense) in relation to the promoter was determined by restriction enzymes and sequencing. Then, this cassette was transferred to binary vector pZP211 and these cassettes were transferred into Agrobacterium tumefaciens LBA4404. S. lycopersicum cv. Micro-Tom (MT) and MT-Rg1 plants were transformed. In addition, seedlings were subjected to hormone treatments using a synthetic auxin (- naphthalene acetic acid) and cyclosporin A (cyclophilin inhibitor) treatments and it was found that the hormone treatment there were changes in development of lateral roots pattern, probably related to decreases in auxin signaling caused by reduction of LeCYP1 in MT-dgt plants while cyclosporin A treatments, there was a slight delay in flowering in cv. MT plants. Furthermore, assay with real-time PCR (RT-qPCR) were done for expression level analysis from LeCYP1 and ARP in order to functionally characterize these sequences in tomato plants.

Análise filogenética e funcional de dois genes de reparo homólogos a AP endonuclease em cana-de-açúcar: ScARP1 e ScARP3

The genome of all organisms constantly suffers the influence of mutagenic factors from endogenous and/or exogenous origin, which may result in damage for the genome. In order to keep the genome integrity there are different DNA repair pathway to detect and correct these lesions. In relation to the plants as being sessile organisms, they are exposed to this damage frequently. The Base Excision DNA Repair (BER) is responsible to detect and repair oxidative lesions. Previous work in sugarcane identified two sequences that were homologous to Arabidopsis thaliana: ScARP1 ScARP3. These two sequences were homologous to AP endonuclease from BER pathway. Then, the aim of this work was to characterize these two sequence using different approaches: phylogenetic analysis, in silico protein organelle localization and by Nicotiana tabacum transgenic plants with overexpression cassette. The in silico data obtained showed a duplication of this sequence in sugarcane and Poaceae probably by a WGD event. Furthermore, in silico analysis showed a new localization in nuclei for ScARP1 protein. The data obtained with transgenic plants showed a change in development and morphology. Transgenic plants had slow development when compared to plants not transformed. Then, these results allowed us to understand better the potential role of this sequence in sugarcane and in plants in general. More work is important to be done in order to confirm the protein localization and protein characterization for ScARP1 and ScARP3

Ambiente computacional paradesenvolvimento de aplicações de controladores lógicos programáveis baseado em linguagens SFC e ST

This work proposes an environment for programming programmable logic controllers applied to oil wells with BCP type method of artificially lifting. The environment will have an editor based in the diagram of sequential functions for programming of PLCs. This language was chosen due to the fact of being high-level and accepted by the international standard IEC 61131-3. The use of these control programs in real PLC will be possible with the use of an intermediate level of language based on XML specification PLCopen T6 XML. For the testing and validation of the control programs, an area should be available for viewing variables obtained through communication with a real PLC. Thus, the main contribution of this work is to develop a computational environment that allows: modeling, testing and validating the controls represented in SFC and applied in oil wells with BCP type method of artificially lifting

Caracterização funcional de dois cDNAs de cana-de- açúcar : PKCI e SHAGGY

Flowering is controlled by several environmental and endogenous factors, usually associated with a complex network of metabolic mechanisms. The gene characterization in Arabidopsis model has provided much information about the genetic and molecular mechanisms that control flowering process. Some of these genes had been found in rice and maize. However, in sugarcane this processe is not well known. It is known that early flowering may reduce its production up to 60% at northeast conditions. Considering the impact of early flowering in sugarcane production, the aim of this work was to make the gene characterization of two cDNAs previously identified in subtractive cDNA libraries: scPKCI and scSHAGGY. The in silico analysis showed that these two cDNAs presented both their sequence and functional catalytic domains conserved. The results of transgenic plants containing the overexpression of the gene cassette scPKCI in sense orientation showed that this construction had a negative influence on the plant development as it was observed a decrease in plant height and leaf size. For the scPKCI overexpression in antisense orientation it was observed change in the number of branches from T1 transgenic plants, whereas transgenic T2 plants showed slow development during germination and initial stages of development. The other cDNA analyzed had homology to SHAGGY protein. The overexpression construct in sense orientation did not shown any effect on development. The only difference observed it was an increase in stigma structure. These results allowed us to propose a model how these two genes may be interact and affect floweringdevelopment.

Comportamento adaptativo de Lutzomyia longipalpis (Diptera: Psychodidae) às áreas urbanas da cidade de Teresina-PI.

The sand fly Lutzomyia longipalpis (Diptera: Psychodidae) is currently appointed as the main vector of visceral leishmaniasis in the Americas. The growth of cities in areas originally endemics to American Visceral Leishmaniasis (AVL) resulted in the spread of the disease at the same time that observed the adaptation of this species to the urban environment.Changes in behavior of L.longipalpis that enabled the adapt to increasing losings of biodiversity, as well as the frequent exposure of the vector to insecticides evident in urban areas, could justify the increasing population of the species and consequently the spread of disease for these environments .Thus, we selected sixty houses spread among three areas with increasing stages of occupation of an area endemic for AVL in Teresina-PI. We evaluated the correlation between the density of L.longipalpis captured and different aspects, such as population density of animals, vegetation cover and socio-economic aspects in each house. In addition to the correlations, the feeding preference of the vector between the predominant plant species in the neighborhoods, as well as the presence of metabolic mechanisms of resistance among the captured insects were tested. The results showed that over the growing occupations, represented by three areas, L.longipalpis demonstrate its adaptive nature through an apparent opportunistic behavior in relation to sources of carbohydrates and blood. On the evolutionary point of view, this behavior may have favored its vector competence in urban areas among the limited presence of food sources, as well as in various environments encountered.

Apitidão funcional e comportamentos relacionados à saúde em mulheres idosas do município de Jequié-BA

The identification of the factors that interfere in the decline of functional conditions is useful in the planning of actions addressing the improvement in the conditions of the lives of elderly people. The purpose of this investigation was to analyze the relationship between social demographics and health aspects of the functional condition in elderly women of low income of the Brazilian northeast. This crosssectional study involved a representative sample of 222 women with an average age of 70 years (± 7.1), belonging to coexisting groups and that were resident in the urban area of the municipal district of Jequié /Bahia. In order to achieve this objective, a battery of physical tests of functional aptitude was carried out previously tested in pilot study, anthropometric measurements collected with a comparison of the measures referred to the reported weight and height as well as the application of an interview with questions containing subjects related to social demographic variables, clinical conditions and health, physical conditions and behaviors. Descriptive statistics Proceedings (frequency, average, standard deviation and percent distribution) were used for statistic analysis, and the calculation of the respective odds ratio by binary logistics regression, for the analysis of factors hierarchically grouped; p<0.05. The prevalence of 56% (n=122) of women considered with moderated or serious type of functional limitations was found, In which from multi-varied hierarchical analysis, significant association was verified with the age group over 80 years (p=0.02), conditions of widowhood (p=0.04), presence of arterial hypertension (p=0.001), and physical inactivity during leisure time (p=0.03). On the other hand for functional incapacities the prevalence was of 46.8% (n=104) being associated to the increase of the age (p=0.01), hospitalization (p=0.02), absence of physical activities along their lives (p=0.001) and the occurrence of alterations in the cognitive function (p=0.001). The normative table for the parameters of physical fitness generated conducive to health professionals in the diagnosis of health conditions and the prescription of physical exercises. The identified characteristics that are associated with the functional limitations / functional incapacities suggest a complex causal net in the determination of the functional condition in elderly women. However, actions addressed to the incentive of the practice of physical activities in the leisure time and the preservation of the cognitive function can contribute to a life with more quality for these people. This research was multidisciplinary approach to involve elements of psychology, nutrition and Physical Education in the elucidation of the object of study related to the functional condition of elderly women

Alterações de linguagem oral e escreta em crianças pré-escolares e escolares com epilepsia

A epilepsia cursa com diversas comorbidades e, entre elas, estão as alterações de linguagem, que levam a criança a problemas educacionais e sociais desfavoráveis. A etiologia das alterações de linguagem envolve aspectos orgânicos, cognitivos e sociais, ocorrendo, na maioria das vezes, uma interrelação entre todos esses fatores. A idade da primeira crise epiléptica, o tipo de epilepsia, o uso de drogas antiepilépticas e a intervenção medicamentosa em politerapia podem implicar na ocorrência dessas alterações em crianças. O objetivo dessa pesquisa foi verificar a ocorrência de alterações de linguagem em crianças pré-escolares e escolares com diagnóstico de epilepsia atendidas no setor de Neurologia Infantil do Hospital de Pediatria Professor Heriberto Ferreira Bezerra. Caracterizou-se como um estudo prospectivo e transversal realizado com 90 crianças com epilepsia, submetidas à avaliação fonoaudiológica de linguagem oral e de leitura e escrita e como pesquisa interdisciplinar uma vez que envolveu áreas como a Fonoaudiologia, a Neurologia e a Psicologia. Os critérios de inclusão foram: 1) diagnóstico inequívoco de epilepsia, segundo a definição da ILAE (2005), 2) idade de 3 aos 12 anos, 3) padrão neurológico e desenvolvimento neuropsicomotor normais; os de exclusão: 1) diagnóstico de epilepsia duvidoso, 2) padrão neurológico e desenvolvimento neuropsicomotor alterados, 3) crianças com patologias pediátricas associadas. Foram analisadas as seguintes variáveis: sexo, idade da primeira crise epiléptica, tipo de crise epiléptica, regime de tratamento, presença de crise epiléptica, frequência à escola, tipo de escola e repetência. A análise estatística centrou-se na análise descritiva; determinou-se a razão de chances (odds ratio), adotando-se um intervalo de confiança de 95%; e na aplicação do teste exato de Fisher, levando-se em consideração p<0,05. Portanto, no que se refere à presença de alterações de linguagem oral, pôdese observar que o início das crises epilépticas durante o período de aquisição e desenvolvimento da linguagem oral bem como o tratamento medicamentoso neste período podem interferir no desenvolvimento da linguagem devido à imaturidade do sistema nervoso central além dos aspectos socioambientais, uma vez que o estigma e as crenças errôneas interferem negativamente no processo interacional tão importante para a aquisição e desenvolvimento da linguagem, o que também repercute nas habilidades de leitura e escrita. Dessa forma percebe-se a importância da atuação de uma equipe interdisciplinar (Fonoaudiologia, Psicologia e Neurologia Infantil) no processo avaliativo e no acompanhamento dos pacientes com epilepsia, o que trará benefícios psicosocioafetivos no que se refere à reorganização da sua qualidade de vida e, consequentemente, de seus familiares.

Influência da dor na capacidade funcional de idosos institucionalizados

The aim of this study was to evaluate the pain influence regarding location, intensity and duration over functional capacity in institutionalized elderly (Fundacao Leur Brito). This is a descriptive exploratory study with a transversal design and quantitative approach. The population of the study was composed of 60 elderly, being 50% males with 60 years-old minimum age and 104 years-old maximum age, with mean age 77,6 (?}11,64) years-old. Data was collected by a structured query formulary divided in four parts: 1) Social, health and demographic characterization; 2) Pain related aspects (time and location); 3) Pain evaluation by numeric scale and 4) Functional capacity measured by Barthel Index. It was observed after evaluation by Squared-chi test (x2) statistical significant difference between pain presence and Barthel Index activities: bath (pvalue=0,015), dressing (p-value= 0,041), intimal hygiene transference (p-value=0,001), chair and bed transference (p-value=0,032), walking (p-value=0,010) and go upstairs (p-value=0,008). It was also observed statistical difference between total Barthel score (dependent/independent) and pain presence, p-value<0, 000. Through data obtained by this study, a multiprofessional approach is necessary to proper pain control and maintenance and/or regain of functional capacity, leading to an increase in life quality with more independence and autonomy to elderly
