Estratégias de aprendizagem utilizadas por estudantes cegos

Learning strategies can be understood as a planned sequence of procedures or activities, selected in order to facilitate the acquisition, storage and use of information. Although important to the learning process, the knowledge on these strategies is still insufficient, especially with regard to students with visual impairments. Therefore, this study aimed to characterize learning strategies used by blind and sighted students, registered in elementary education in schools and special institutions. Were participants 23 teachers, male and female, aged between 26 and 51 years, and 102 students, of whom 25 were blind and 77 seers, of both genders, registered on the 3rd to the 9th grade of elementary school, aged 7 to 16 years old. The instruments used were: field diary (students and teachers); structured questionnaire (teachers); sociodemographic questionnaire, interview and Assessment Scale of Learning Strategies for Elementary School (students). Initially were made observations in the classroom and the teachers received the questionnaires, with instructions for completion. Then were made the interviews with blind students and the scale was administered with these and with the seers. All instruments were administered individually. We conducted content analysis of the questionnaires with teachers and the interviews with blind students. The scale of strategies and sociodemographic questionnaire were analyzed with the help of descriptive and inferential statistics. It was noticed that the blind students use few learning strategies in the classroom, regardless of city, series, sex or age. It was found that teachers didn t receive training to deal with blind students, either during graduation or after have completed it, in such a way that few of them were able to inform about the learning strategies the students use, and demonstrated low ability to deal with these inefficiencies. It was also found that the blind and the sighted use cognitive and metacognitive strategies during learning, but those used by the blind seem to be more basic, low complexity, given that the seers have achieved higher scores on all subscales. We conclude that the repertoire of learning strategies for blind students is inflexible, requiring increments so that they can achieve significant results. It is important that teachers receive training to understand the learning strategies and how they positively influence learning

Promoção da saúde: estratégias para a autonomia e qualidade de vida do sujeito com diabetes

O diabetes é uma doença crônico-degenerativa de grande prevalência na população mundial configurando-se enquanto sério problema de saúde pública. Por ser crônico exige dos sujeitos autocuidado e autogoverno longitudinal. A autonomia, por sua vez, é um direito fundamental e também um dos princípios da bioética mais discutidos na atualidade. Seu conceito é complexo e leva em conta a vida experimentada ao longo dos anos. Quando a discussão sobre autonomia se trata de diabetes, a dependência do outro e os conflitos no controle da doença, diante de novas regras e estilos de vida, nem sempre condizentes com os valores dos pacientes, torna-a fragilizada. Embora a autonomia seja claramente parte integrante do tratamento e alicerce para uma vida digna e de qualidade, observamos que os sujeitos se tornam ainda mais dependentes dos serviços de saúde, quando se deparam com o diagnóstico e não têm confiança para tomar suas próprias decisões diante da patologia limitadora. Por isso, há a necessidade dos serviços de atenção primária à saúde traçarem estratégias para promover a saúde desses sujeitos. Os Grupos de Promoção da Saúde são estratégias recentemente utilizadas para influenciar no nível de autonomia dos sujeitos, pois possibilitam, respeitando os limites éticos, a garantia de participação decisória no grupo, através de estratégias e treinamentos de habilidades com competências claramente definidas, que favorecem o empowerment e o protagonismo dos sujeitos. Desse modo, este trabalho objetiva identificar estratégias no âmbito da promoção da saúde na ESF, que contribuam para melhor autonomia e qualidade de vida dos sujeitos com diabetes mellitus, a partir de sua percepção. E, mais especificamente, analisar o perfil clínico e socioeconômico dos portadores de diabetes da ESF; identificar as experiências, necessidades e expectativas dos sujeitos com diabetes sobre autonomia, autocuidado e qualidade de vida; e realizar um levantamento em conjunto com os sujeitos com diabetes, sobre aspectos que sirvam de evidências para construção de propostas para implantação de um Grupo Estratégico de Promoção da Saúde GEPS, com foco na autonomia. Para isto, foi realizada uma pesquisa exploratória descritiva de abordagem qualitativa e quantitativa, com 65 sujeitos com diabetes acompanhados por uma Unidade de Saúde da Família do Município de Santa Cruz/RN. A pesquisa foi realizada em três etapas interdependentes: 1) coleta de dados clínicos e socioeconômicos, para o qual foi utilizado entrevista estruturada e análise retrospectiva dos registros feitos em seu prontuário; 2) a análise das experiências, necessidades e expectativas dos sujeitos sobre autonomia, autocuidado e qualidade de vida, que se utilizou de entrevista semiestruturada com 6 sujeitos, sendo 3 com mais e 3 com menos complicações autorreferidas e verificadas no prontuário; e 3) a construção coletiva de propostas para melhor autonomia e qualidade de vida dos próprios participantes do estudo, por meio de roda de conversa. Para a análise dos dados utilizamos software de estatísticas simples para os dados das questões fechadas de cunho quantitativo e os dados qualitativos foram analisados através da análise de conteúdo. Observamos que o perfil clínico e socioeconômicos dos sujeitos com diabetes aproximam-se das estatísticas nacionais, embora existam variáveis, como cor da pele, com variação significativa. A autopercepção dos sujeitos diante de algumas complicações divergem de registros encontrados em seu prontuário o que aponta uma possível desvalorização de queixas como hipoglicemia e disfunção sexual, como também baixa adesão ao tratamento por, muitas vezes, não terem suas opiniões valorizadas. As categorias encontradas: vida, qualidade de vida, diagnostico e enfrentamento do problema, autonomia, limites e dependência assim como as práticas coletivas de promoção da saúde, apontam para a necessidade de estratégias por meio de grupos que considerem as crenças e valores dos sujeitos, favoreçam sua emancipação e torne-os protagonistas de sua própria história e de seu processo saúde doença. A autonomia é fundamental para o exercício da cidadania efetiva. É por meio dela que os sujeitos transformam sua realidade e a si mesmo. A contribuição desta pesquisa consiste em identificar estratégicas que se propõe a potencializar a autonomia dos sujeitos, através dos GEPS, norteando a atuação dos profissionais na atenção primária à saúde, que deve sustentarse em ações de prevenção e promoção da saúde e também no incentivo à participação popular e protagonismo dos sujeitos

Ofensiva do Capital e Desmobilização das Forças do Trabalho: As Estratégias Gerenciais Burguesas para a Desarticulação das Classes Trabalhadoras

The problematic that gives shape to this research is the question of the historical process of demobilization of the movement of the working classes in your accented contemporary moment. Their object of study, however, and that it particularizes, it relates to a portion this problematic; it relates to set of determinations that comprise a broader set of determinations of this historical process: it is a set of determinations forged and mediated by bourgeois strategies of management for the conformation of the circumstances necessary for the domination and for the conduct of labor force on operations in work processes for the production of surplus value. What we investigated are, because, the strategies of disarticulation that the bourgeoisie utilizes, under the mantle of subsidies conceptual and interventive of its management of work processes and the sieve of class struggles, to obstruct the union of workers; hamper the movements proletarians. Managerial strategies that intentionally or unintentionally, instill in the social relations of production means to produce and reproduce, activate and reactivate conditions of incitement of individualism and competition between the workers themselves. We shall see, thus, by analyzing means, centrally, from some of the fundamentals of disarticulation in the managerial strategies bourgeois and some of the fundamental strategies of management bourgeois hegemonized with the restructuring productive of 1970, that the disarticulation, and also the demobilization, is a concrete condition, is an objective condition, that is beyond a question that can be "solved" only by enlightenment cognitive, only by formation criticism intellectual. In everyday of the work spaces permeated by managerial strategies bourgeois there elements, then, operating as a material force putting difficulties important for the articulation of the workers, the solidarity of the proletariat; elements that constitute obstacle significant to an awareness of class and belonging; elements act in favor of the atomization of the worker - even if engenders, in the same process, as a contradiction, potentiality of resistance and fight the forces of labor

Genética e biologia reprodutiva de vriesea minarum (Bromeliaceae): em busca de estratégias de conservação no quadrilátero ferrífero, minas gerais

Vriesea minarum is a rupiculous bromeliad species, with naturally fragmented populations, restricted to the Iron Quadrangle, Minas Gerais, Brazil. It is a threatened species, which is suffering from habitat loss due to the growth of cities and mining activities. The knowledge of genetic variability in plant populations is one of the main branches of conservation genetics, linking genetic data to conservation strategies while the knowledge about plant reproductive biology can aid in understanding key aspects of their life story, as well as in the comprehension of their distribution and survival strategies. Thus, the study of diversity, richness, and genetic structure, as well as the reproductive biology of populations of V. minarum can contribute to the development of conservation actions. Chapter 1 presents the transferability of 14 microsatellite loci for V. minarum. Among the results of this chapter, we highlight the successful transferability of 10 microsatellite loci described for other species of Bromeliaceae, all of which are polymorphic. In Chapter 2, we present the genetic analyses of 12 populations of V. minarum that are distributed throughout the Iron Quadrangle. We used the 10 microsatellite loci tested in Chapter 1. The results show a low population structuring (Fst = 0.088), but with different values of genetic richness (mean = 2.566) and gene diversity (mean = 0.635) for all populations; and a high inbreeding coefficient (Gis = 0.376). These may be the result of pollinators action and/or efficient seed dispersal, thus allowing a high connectivity among populations of naturally fragmented outcrops. The reproductive biology and floral morphology of a population of V. minarum, located in the Parque Estadual da Serra do Rola-Moça, are studied in Chapter 3. This reserve is the only public environmental protection area where the species occurs. As a result of field experiments and observations, we found that the species has its flowering period from January to March, with flowers that last for two days and that it has a mixed pollination syndrome. It is primarily alogamous, but also has the capacity to be self-ferilized. It is expected that data obtained in chapters 1, 2 and 3 serve as basis for other studies with species from the ferruginous rocky fields, since until now, to our knowledge, there are no other survey of endemic species from the Iron Quadrangle, seeking to merge the genetic knowledge, with the data of the reproductive biology, with the ultimate aim of biodiversity conservation. Considering the great habitat loss for the species by mining, it becomes crucial to analyze the creation of new protected areas for its conservation

Desenvolvimento local e responsabilidade social empresarial: estratégias de cidadania ou marketing social?

As transformações em curso no sistema mundial evidenciaram, dentre outros aspectos, a necessidade de (re) significação da noção de desenvolvimento e a compreensão das modificações significativas na relação Estado, mercado e sociedade. Nesse cenário, redefinemse papéis de atores sociais, que passam a fazer parte da efetivação de propostas de desenvolvimento que se materializam nos espaços locais. Em meio a essa reconceituação, pode-se incorporar a dimensão da responsabilidade social empresarial. Assim, desmistifica-se a globalização como geradora de um modo homogêneo de vida, permitindo visualizar outra sociabilidade possível, induzida pelo agir multifacetado dos participantes da dinâmica local

Estratégias de Produção in vitro de Bioinseticida Viral: influências do Isolado, da Cinética e do Modo de operação

Societal concerns about environmental sustainability has lead to the development of ecologically-friendly alternatives to chemical insecticides for crop protection. One such alternative is biological pest control. In particular, baculoviruses are well suited as insect biopesticides due to their narrow host specificity and relative ease of propagation. In Brazil, the baculovirus Anticarsia gemmatalis nucleopolyhedrovirus (AgMNPV) is the main biological control agent employed for the soybean pest, Anticarsia gemmatalis. This baculovirus biopesticide is currently produced using caterpillars, but increasing market demand for the product has encouraged the development of an in vitro manufacturing process, which can be scaled up to much higher virus productivities. In this study, three wild-type AgMNPV isolates (AgMNPV-2D, AgMNPV-MP2 and AgMNPV-MP5) and a recombinant form (vAgEGT-LacZ) were characterised in terms of occlusion body (OB) production and infection kinetics, to enable future optimisation of the in vitro production process. These viruses were propagated using a Spodoptera frugiperda (IPLB-SF21) insect cell line grown in shaker-flask batch cultures. Among the virus isolates tested, AgMNPV-MP5 was found to be the best producer, yielding (5.3±0.85)x108 OB/mL after 8 days post infection. The characterisation of vAgEGT-LacZ propagation in suspension cell cultures has not been previously reported in the literature; hence it became the main focus for this thesis. In particular, it was carried out a study on the effect of the multiplicity of infection (MOI) on OB production. Five successive batches were performed getting a final production (8.9±1.42)x1014 occlusion bodies, considering that production is related for a bioreactor with final volume of 10m3. A low MOI associated with a fed-batch process for vAgEGT-LacZ production was found to support a 3-fold higher OB yield when compared to the default batch process (1.8x107 and 5.3x107 OB/mL, respectively). This yield is competitive with regards to the production process.

Estudo comparativo de estratégias de controle aplicadas a um gerador síncrono

The robustness and performance of the Variable Structure Adaptive Pole Placement Controller are evaluated in this work, where this controller is applied to control a synchronous generator connected to an infinite bus. The evaluation of the robustness of this controller will be accomplished through simulations, where the control algorithm was subjected to adverse conditions, such as: disturbances, parametric variations and unmodeled dynamic. It was also made a comparison of this control strategy with another one, using classic controllers. In the simulations, it is used a coupled model of the synchronous generator which variables have a high degree of coupling, in other words, if there is a change in the input variables of the generator, it will change all outputs simultaneously. The simulation results show which control strategy performs better and is more robust to disturbances, parametric variations and unmodeled dynamics for the control of Synchronous Generator

A integração do tutorial interativo TryLogic via IMS Learning Tools Interoperability: construindo uma infraestrutura para o ensino de Lógica através de estratégias de demonstração e refutação

Logic courses represent a pedagogical challenge and the recorded number of cases of failures and of discontinuity in them is often high. Amont other difficulties, students face a cognitive overload to understand logical concepts in a relevant way. On that track, computational tools for learning are resources that help both in alleviating the cognitive overload scenarios and in allowing for the practical experimenting with theoretical concepts. The present study proposes an interactive tutorial, namely the TryLogic, aimed at teaching to solve logical conjectures either by proofs or refutations. The tool was developed from the architecture of the tool TryOcaml, through support of the communication of the web interface ProofWeb in accessing the proof assistant Coq. The goals of TryLogic are: (1) presenting a set of lessons for applying heuristic strategies in solving problems set in Propositional Logic; (2) stepwise organizing the exposition of concepts related to Natural Deduction and to Propositional Semantics in sequential steps; (3) providing interactive tasks to the students. The present study also aims at: presenting our implementation of a formal system for refutation; describing the integration of our infrastructure with the Virtual Learning Environment Moodle through the IMS Learning Tools Interoperability specification; presenting the Conjecture Generator that works for the tasks involving proving and refuting; and, finally to evaluate the learning experience of Logic students through the application of the conjecture solving task associated to the use of the TryLogic

As estratégias de negação variantes no inglês falado: uma comparação com o português

The general aim of this work is to verify the occurence of variant forms of negation in spoken English with the purpose of making a comparative study between the English and the Portuguese languages. As for Portuguese, we used as a matter of reference a study already made on negation. As for English, we analized a corpus of the North American English variant organized by a university in the United States. This study is based on the North American Functional Linguistics theoretical perspective, which considers relevant the study of language used in real situations of communicative interaction. The data analisys proved that there is at least one form of negative variant in spoken English which is not allowed by prescriptive grammar. This phenomenon turns out to be similar to Portuguese, which includes three variant strategies. According to the data obtained, it was possible to verify that the variant strategy used in English, from a contrastive point of view, corresponds to a negative strategy ruled by Portuguese prescriptive grammar. Finally, we discussed about the different conceptions of language, grammar and teaching, giving suggestions to colaborate to a productive and reflexive teaching of first or second language
