O ritual simbólico do Ctrl+C (copiar ) e Ctrl+V (colar) no ensino médio

Nowadays, technology has a direct influence on the relationship student and teacher have with language. The internet is a powerful tool in helping work with the language and, through it, the knowledge comes to the student easily and intensely. Furthermore, this facility has enhanced and made visible what has been called, within the University community, "plagiarism generation." This work assumes that this generation has, in their written texts, symbolic movements similar to those of "copy and paste" applied to research work carried out by high school students. Taking this as starting point, this dissertation aims to analyze how high school students of the 1st year from a school in Natal (RN) construct texts, under the movements known as "Ctrl + c" and "Ctrl + v", with reference to the text of the "other". More specific issues are behind the general objective, namely: 1. how the student appropriates the source-text when he copies and pastes? 2. What are the categories of analysis that allow us to look analytically and theoretically for the "ctrl + c / ctrl + v" practice made by the student? 2. how the studies developed in the fields of "Genetic Criticism" (Grésillon, 1987), the "school manuscripts" (Calil, 2004) and "paraphrase" (Fuchs, 1982) may help in working with writing in the classroom standing as a possible way to minimize the copy and paste effects in the students texts? Thus, we observe the categories of analysis that allow us to look, theoretically and analytically, for the symbolic ritual of the "ctrl + c" (copy) and "ctrl + v" (paste) in high school. Our study shows that the student text is a "hybrid body" whose writing is a drawing entanglement because of the presence of the foreign text, verbatim, and the presence of linguistic elements to paraphrase the original text.This textual embodiment has, behind it, certain operations, namely: replacing, moving, adding and deleting statements. Given the specificity of the data and the research objectives, this study aligns with qualitative research methods (SILVERMAN, 2009) and falls within the knowledge field of Applied Linguistics, which is characterized especially by investigating problems, phenomena in which language in a real situation is taken as central (BRUMFIT, 1995).Theoretically, our work follows the approach of studies on the paraphrase (Fuchs, 1982, 1994a, 1994b; DAUNAY, 1997, 1999, 2002a, 2002b), the studies developed in the field of Genetic Criticism (Grésillon, 1987, 1994, 1992, 2008 ) and those developed by Eduardo Calil (2004) on "school manuscripts"

Síndrome da fragilidade e fatores associados em idosos comunitários do município de Santa Cruz RN

The frailty in the elderly is characterized by decreased physiological reserves, and is associated with increased risk of disability and high vulnerability to morbidity and mortality. This study is part of a multicentric project on Frailty in Elderly Brazilians (REDE FIBRA). Aims: to investigate characteristics, prevalence and associated factors related to frailty. Metodology: We interviewed 391 elderly patients aged 65 years, selected randomly. Data collection was performed using a multidimensional questionnaire containing information about socio-demographic and clinical variables. To characterize the frail elderly, was considered the phenotype proposed by Fried. Data were analyzed using descriptive statistics, bivariate analysis (χ ²) and binary logistic regression. Results: The prevalence of frailty was 17.1%. In the final model of multivariate analysis, was obtained as factors associated with frailty: advanced chronological age (p <0.001), have comorbidity (p <0.035), show dependence on performing basic activities of daily living (p <0.010) and instrumental (p <0.003) and have poor perception of health status (p <0030). Conclusions: The factors associated with frailty suggest a predictive model helping to understand the syndrome, guiding actions that minimize adverse effects on the aging process

Comportamento social e territorialidade alimentar na garça-azul, Egretta caerulea (L) = Feeding territoriality in the little blue heron, Egretta caerulea (L)

The use of habitat is an important part of a species biology. One resource of great importance for the survivor and reproduction of an individual is the food resource. Thus, the social interactions an animal has during the feeding activities are of extremely importance within its behavioral aspects, which represents the part of an organism trough which it interacts with the environment, adapting to changes and variations. Herons are known to form feeding aggregations of even more than thousands of individuals, in which social components of foraging have been identified and studied for several species. More profound studies of these aspects are yet to poor for the Little Blue Heron, Egretta caerulea. Therefore, the aim of this study was to describe the social behavior (display postures, vocalizations and co-specific interactions) and the territoriality of the specie during the feeding period in an area of mud bank in the estuarine system of Cananéia, south coast of São Paulo state, Brazil. The defense of a fixed and exclusive area, closest to the mangrove, trough expulsion was observed; some thing that have not yet been registered with concrete data for the specie. Higher capture and success rates, and lower investment rates (steps/min and stabs/min) were registered for individuals foraging in areas corresponding to the defended territory. This could be one of possible reasons for the establishment of territories in the area. Four display postures were registered for the specie, two of then new in the literature, which are used in the interactions between individuals; one vocalization, that apparently is important in the social context of foraging for the specie and, possibly, has a function of advertising and proclaiming the dominance position of the territorial individual within the group. A territorial individual uses three behaviors, of the ones described: expulsion, vocalization and encounter (agonistic encounter between individuals, without physical aggression). Of these, the expulsion is apparently used in the actual defense, actively; while the other two behaviors are used in a more passive way, in the maintenance of the dominance position of the individual, helping it in the defense of its territory in a less direct manner. Therefore, with the results presented in here, new components of the social utilization of the feeding resource for the Little Blue Heron were identified, incorporating aspects of the territorial behavior for a future understanding of its possible adaptive significance. And it also reinforces the importance of the social interactions of herons foraging in great aggregations, in areas ecologically important

Psicose e toxicomanias: um estudo psicanalítico

This paper is a case study that aims to discuss the effects of drug abuse by a person with psychotic structure from a psychoanalytical perspective. The interest in this subject was born from an internship experience in the Mental Health area in which a psychotic patient had a drug abuse problem and the service treating him had difficulties dealing with this. In order to accomplish the objective of this work four theoretical chapters were written and the case is discussed throughout them articulating the theoretical issues with clinical practice. A literature review revealed that Freud and Lacan did not dedicate themselves to the study of the effect of drug use by psychotic patients but they made important contributions unfolding the theoretical and clinical psychoanalytical practice. Contemporary psychoanalytic authors suggest that the drug use made by psychotics differs from the use by neurotics, because of the particularity of the psychotic structure. It was found that drug use in psychosis can operate in three different ways: the first refers to drug use as substitute of a missing signifier helping the psychotic patient building a social bond. The second function is to intensify psychotic phenomena and the third function is to operate as an attempt to diminish those same phenomena. We conclude that, while the use of drugs in neurosis provides an individualist way of satisfaction, that excludes social aspects. For psychosis such use may operate differently and may play a role in social integration, among others effects. Such discussion can help move forward the direction of treatment of psychosis when the case involves drug use

Projeção retiniana, caracterização citoarquitetônica e neuroquímica da zona incerta do moco (Kerodon rupestris)

The Zona Incerta (ZI) is embryologically derived from the ventral thalamus, in continuity with the reticular nucleus of the thalamus. Studies usingneural tracers technics have allowed identify a complex connectional map including the ZI. Futhermore, cytochemical, molecular and functional data have shown abundant variability in the neurochemical contend in the ZI, as well as,the involvement of the ZI in the modulation of nociception, attention, alertness, control and maintenance of posture and control of visceral activity. This work aims to characterize the cytoarchitecture, neurochemical content of the ZI in the rock cavy (Kerodon rupestris), and a direct retinal-ZI pathway present in this species. The Nissl staining is effective for the delineation and characterization of ZI citoarchitecture. ZIc receives a contralateral retinal projection showing varicosities, suggesting a modulatory character of photic information. The ZI in the rock cavy, as in others rodents and primates, is characterized by a complex neurochemical signature. The ZI neurochemistry presents great diversity, especially in the medial portion of ZIr, where we have found immunoreactivity of all neuroactive substances investigated, and that NOS-IR, GFAP and CR helped the delimitation of middle ZI in ZId and ZIv. Nevertheless, just 5-HT-IR fibers are present in all subdivisions of the ZI. These data demonstrate the great wealth of the neurochemistry of rock cavy s ZI and a direct retinal modulation in the ZI, helping to explain it s broad functional repertory

A manifestação da vontade da criança na disputa judicial da guarda: escuta psicanalítica/

Currently, in custody disputes, the child has the right to be heard and to have its opinion considered, according to its age and maturity. The psychologist/psychoanalyst who works in the Family Court is required to produce a Report with the purpose of helping the Court´s decision. The present research aims to discuss and to find guiding principles for the hearing of the declaration of the child´s will in a custody dispute by its parents, from a psychoanalytical perspective. The case of a nine year old girl that affirmed in Court the desire of living with the mother and seeing the father only once a year is the starting point of this theoretical research over the psychoanalytic fundaments of the hearing of the case, how it appeared in that experience and how it was reflected in the report. Throughout this work, the peculiarities of psychoanalysis as a way of understanding the subject and the conditions that must be observed so that a sctrictu sensu analytic hearing is possible are studied. Then we present a reflection of the case, in the light of the theories studied, verifying that we could observe in the experience: i) the assumption of a subject of the unconscious, divided and desire full that constitutes itself from the oedipic structuration, that leads to the difference between speech and speak; ii) the concept of the child as having a sexuality of its own; iii) a hearing based on the ethic principles of psychoanalysis and the analysts'' formation. In the final considerations, we state that the institutional demand of a meaning for the case is a great difficulty for the analyst since he works from a place of 'not-knowing"

Nem tudo que reluz é ouro: oficinas terapêuticas no cenário da Reforma Psiquiátrica

The purpose of this study is to discuss the therapeutic workshops function, while questioning if they constitute a mechanism for change of the traditional asylum logic. The Psychiatric Reform was materialized with the financing and regulation of alternative services that substitute the psychiatric hospital. This change was promoted by the anti asylum debate and the deinstitutionalization besides psychosocial rehabilitation paradigms. Mental health care, therefore, acquired a new form and the Centers for Psychosocial Care (CAPS) are considered the main services of the health network presently under construction. They are services that offer a variety of therapeutics and amongst them is the workshop, considered essential for the advancement of the Reform ideas. The study was conducted in a CAPS II in Natal, RN. Systematic visits were made using the Institutional Analysis perspective, futhermore were made interviews with professionals who was related to workshops. In the end, data were then discussed according to Schizoanalysis. Results denot that workshops represents, in the same time, progress and regress of Psychiatric Reform. It was observed that workshops were oftentimes reduced to strategies for the occupation of time, and as a means for the transmission of social values considered correct. The relationship between professionals and the user of the service was hierarchical and both players was seeing the workshop as a task to be met. Although users expressed intreresting about wokshops, was reported that the work was boring. Besides, except for some cases, the therapeutic workshops wasn t helping clients to create other possibilites in theirs life and stops the job inside the mental care service

X-ARM: um modelo de representação de artefatos de software

A great challenge of the Component Based Development is the creation of mechanisms to facilitate the finding of reusable assets that fulfill the requirements of a particular system under development. In this sense, some component repositories have been proposed in order to answer such a need. However, repositories need to represent the asset characteristics that can be taken into account by the consumers when choosing the more adequate assets for their needs. In such a context, the literature presents some models proposed to describe the asset characteristics, such as identification, classification, non-functional requirements, usage and deployment information and component interfaces. Nevertheless, the set of characteristics represented by those models is insufficient to describe information used before, during and after the asset acquisition. This information refers to negotiation, certification, change history, adopted development process, events, exceptions and so on. In order to overcome this gap, this work proposes an XML-based model to represent several characteristics, of different asset types, that may be employed in the component-based development. Besides representing metadata used by consumers, useful for asset discovering, acquisition and usage, this model, called X-ARM, also focus on helping asset developers activities. Since the proposed model represents an expressive amount of information, this work also presents a tool called X-Packager, developed with the goal of helping asset description with X-ARM

Análise das medidas de boa e má diversidade na construção de comitês de classificadores através de metaheurísticas de otimização multiobjetivo

Committees of classifiers may be used to improve the accuracy of classification systems, in other words, different classifiers used to solve the same problem can be combined for creating a system of greater accuracy, called committees of classifiers. To that this to succeed is necessary that the classifiers make mistakes on different objects of the problem so that the errors of a classifier are ignored by the others correct classifiers when applying the method of combination of the committee. The characteristic of classifiers of err on different objects is called diversity. However, most measures of diversity could not describe this importance. Recently, were proposed two measures of the diversity (good and bad diversity) with the aim of helping to generate more accurate committees. This paper performs an experimental analysis of these measures applied directly on the building of the committees of classifiers. The method of construction adopted is modeled as a search problem by the set of characteristics of the databases of the problem and the best set of committee members in order to find the committee of classifiers to produce the most accurate classification. This problem is solved by metaheuristic optimization techniques, in their mono and multi-objective versions. Analyzes are performed to verify if use or add the measures of good diversity and bad diversity in the optimization objectives creates more accurate committees. Thus, the contribution of this study is to determine whether the measures of good diversity and bad diversity can be used in mono-objective and multi-objective optimization techniques as optimization objectives for building committees of classifiers more accurate than those built by the same process, but using only the accuracy classification as objective of optimization

RR3D: Uma solução para renderização remota de imagens médicas tridimensionais

The visualization of three-dimensional(3D)images is increasigly being sed in the area of medicine, helping physicians diagnose desease. the advances achived in scaners esed for acquisition of these 3d exames, such as computerized tumography(CT) and Magnetic Resonance imaging (MRI), enable the generation of images with higher resolutions, thus, generating files with much larger sizes. Currently, the images of computationally expensive one, and demanding the use of a righ and computer for such task. The direct remote acess of these images thruogh the internet is not efficient also, since all images have to be trasferred to the user´s equipment before the 3D visualization process ca start. with these problems in mind, this work proposes and analyses a solution for the remote redering of 3D medical images, called Remote Rendering (RR3D). In RR3D, the whole hedering process is pefomed a server or a cluster of servers, with high computational power, and only the resulting image is tranferred to the client, still allowing the client to peform operations such as rotations, zoom, etc. the solution was developed using web services written in java and an architecture that uses the scientific visualization packcage paraview, the framework paraviewWeb and the PACS server DCM4CHEE.The solution was tested with two scenarios where the rendering process was performed by a sever with graphics hadwere (GPU) and by a server without GPUs. In the scenarios without GPUs, the soluction was executed in parallel with several number of cores (processing units)dedicated to it. In order to compare our solution to order medical visualization application, a third scenario was esed in the rendering process, was done locally. In all tree scenarios, the solution was tested for different network speeds. The solution solved satisfactorily the problem with the delay in the transfer of the DICOM files, while alowing the use of low and computers as client for visualizing the exams even, tablets and smart phones

Armadilhas cognitivas: o caso das omissões na gênese dos acidentes de trabalho

Neste artigo discute-se o tema das omissões na gênese de acidentes do trabalho, tendo como referência contribuições de James Reason. Os autores descrevem três acidentes de trabalho ocorridos em atividades de manutenção, e nos quais a omissão de passos na execução da atividade foi apontada como causa nas análises efetuadas pelas empresas, acarretando atribuição de culpa aos acidentados. Nos três casos, a análise efetuada pelos autores revelou que, na seqüência de passos da atividade havia presença simultânea de pelo menos quatro das características apontadas por Reason como geradoras de omissões, caracterizando as denominadas armadilhas cognitivas.
