Práticas de letramento digital de professores em formação: demandas, saberes e impactos

Over the last decades, the digital inclusion public policies have significantly invested in the purchase of hardwares and softwares in order to offer technology to the Brazilian public teaching institutions, specifically computers and broadband Internet. However, the teachers education to handle these artefacts is put away, even though there is some demand from the information society. With that, this dissertation chooses as an object of study the digital literacy practices performed by 38 (thirty-eight) teachers in initial and continuous education by means of the extension course Literacies and technologies: portuguese language teaching and cyberculture demands. In this direction, we aim at investigating the digital literacy practices of developing teachers in three specific moments: before, while and after this extension action with the intent to (i) delineate the digital literacy practices performed by the collaborators before the formative action; (ii) to narrate the literacy events made possible by the extension course; (iii) to investigate the contributions of the education course to the collaborators teaching practice. We sought theoretical contributions in the literacy studies (BAYNHAM, 1995; KLEIMAN, 1995; HAMILTON; BARTON; IVANIC, 2000), specifically when it comes to digital literacy (COPE, KALANTZIS, 2000; BUZATO, 2001, 2007, 2009; SNYDER, 2002, 2008; LANKSHEAR & KNOBEL, 2002, 2008) and teacher education (PERRENOUD, 2000; SILVA, 2001). Methodologically, this virtual ethnography study (KOZINETS, 1997; HINE, 2000) is inserted into the field of Applied Linguistics and adopts a quali-quantitative research approach (NUNAN, 1992; DÖRNYEI, 2006). The data analysis permitted to evidentiate that (i) before the course, the digital literacy practices focused on the personal and academic dimensions of their realities at the expense of the professional dimension; (ii) during the extension action, the teachers collaboratively took part in the hybrid study sessions, which had a pedagogical focus on the use of ICTs, accomplishing the use of digital literacy practices - unknown before that; (iii) after the course, the attitude of the collaborator teachers concerning the use of ICTs on their regular professional basis had changed, once those teachers started to effectively make use of them, promoting social visibility to what was produced in the school. We also observed that teachers in initial education acted as more experienced peers in collaborative learning process, offering support scaffolding (VYGOTSKY, 1978; BRUNER, 1985) to teachers in continuous education. This occurred because of the undergraduates actualize digital literacy practices were more sophisticated, besides the fact being integrate generation Y (PRENSKY, 2001)

Ensino do processo de enfermagem: visão dos discentes de graduação de Natal/RN

The nursing process (NP) it s the systematized way of offering humanized care with the objective of reaching the expected results. The concern of the health and education institutions of elaborating implementation strategies of it is growing. The objective of this research was to know the vision of the senior students of the nursing graduation courses from Natal/RN, about the teaching of the NP. It s about a descriptive and exploratory study of the qualitative and quantitative type, done in five teaching institutions of the undergraduate nursing course of the municipality of Natal- RN in 2011. The research was composed by 48 students of the last 2 years of the nursing course. The gathering of the data was done through an online survey with open and closed questions via SurveyMonkey. For the quantitative data it was used the descriptive statistics from Microsoft Office Excel and for the qualitative data the Content Analysis of Bardin. The results pointed a predominance of female students (81,25%) with an age between 21- 39 years old (75,00%) and in the last year of the course (62,50%). As the opinion of the students about the NP two categories emerged: 1) Nursing Process as grounded method in scientific knowledge and established in two stages; 2) Nursing Assistance Quality, with two subcategories: Nursing Process as Nursing Practice and Nursing Process as instrument of improvement of the aid quality and promotion of well-being. In relation to the tuition of the NP the students (45,83%) said that the knowledge on the subject of the instructor was good; 81,25% reported that the professors use a traditional teaching methodology with the problem solving components and 45,83% answered that is addressed in specific disciplines in an isolated way starting from the professional line. The phase of NP that the nursing students have more difficulties of learning and implementing, being mentioned 22 times (29,70%). In relation to the student s difficulties, in the fields of supervised internships, in applying the NP it was stated for 83,50% that the barriers were related to the non implementation of the practice, overwork and the lack of trust of the nurse in the NP. The teaching-care strategies described as the internship fields were: the training of nurses to be able to contribute with the University in the implementation of the service and teaching; and the need of the universities to focus, continuously throughout the course, the NP with the involvement and incentive of the instructors in this process. These results show that the NP for the nursing students is a work methodology of the profession that needs to be implemented effectively in the practical reality for its teaching to turn effective and for the future professionals to be able to bring real contributions in the achievement of systematized actions trying to improve the assistance quality and the nursing actions. It is expected that this study could help bringing some strategies to facilitate the merging between theory and practice in teaching the NP and stimulate a discussion about the topic at the Nursing Schools where the research was held together with the coordinators, instructors and students

Contribuições da pesquisa operacional para gestão da produção e operações : uma análise exploratória da literatura

This research aims to investigate the evolution presented during three decades (1980, 1990 and 2000) of using the tools of Operations Research (OR) as a suport to decision making in Production Operation Management (POM). Hypothesis tests were made to verify the proportional growth of a given area over the decades to the detriment of the areas of facility layout, capacity planning, production scheduling and inventory management. Six journals were selected and from them more than 800 articles were used for classification and analysis in the grounds of review. It also discussed possible ways for future research and comparisons are made with other papers of literature review. As a result, it was found that areas of heuristics and simulation showed a greater quantity of contributions in all POM areas of this study

Infâncias :o lugar do lúdico nas tramas do trabalho infantil

Considering infancy as the socio-historic construction required from the researcher, not only gives problems to the natural character of the human development, that for a long period in the history of psychology has sown to be predominant, but before anything assumes the position in which the vision of the social condition, i.e., for the contexts of the insertion of the human being, is predominant. In this sense, it is not possible to talk about infancy in the singular, once the different developmental contexts enable different forms of immersion in the daily experiences, amongst which this research focuses on the experience of the ludic. According to various theories of development amongst which we emphasize the socio-historic, this element brings important contributions in the processes of the human being constitution. From the legal aspect this recognition is present in the Code of Practice of the Child and Adolescent which considers playing to be a right of the child. However, the childhood of many children have this aspect affected by many factors. It is in the context of this discussion that we developed this research which has as its objective investigate how children in a working environment experience playing on a daily basis. Four children, girls, took part in this research, who develop activities in the process of the usage of cashew nuts. We used interviews, observations, photographs and drawings. The perspective of analysis which guided this task is based on socio-historic and discursive studies. In this way, the elements which constitute the child s discourse, formed from the corpus were: be a child, the ludic culture, the work in the child s life and the perspective of future and change. The participants discourse showed to be conflicting, contradictory, arisen from a specific ideological formation. In the children s daily routine it was possible to verify that there is an existence of a rich ludic culture, even if it is lived in few moments of the day in consequence of the workload

Estudo teórico QTAIM e DFT dos compostos de coordenação: efeito quelato, titanocenos e ligação química

This work is a study of coordination compounds by quantum theory of atoms in molecules (QTAIM), based on the topological analysis of the electron density of molecular systems, both theoretically and experimentally obtained. The coordination chemistry topics which were studied are the chelate effect, bent titanocene and chemical bond in coordination complexes. The chelate effect was investigated according to topological and thermodynamic parameters. The exchange of monodentate ligands on polydentate ligands from same transition metal increases the stability of the complex both from entropy and enthalpy contributions. In some cases, the latter had a higher contribution to the stability of the complex in comparison with entropy. This enthalpic contribution is explained according to topological analysis of the M-ligand bonds where polidentate complex had higher values of electron density of bond critical point, Laplacian of electron density of bond critical point and delocalization index (number of shared electrons between two atoms). In the second chapter, was studied bent titanocenes with bulky cyclopentadienyl derivative π-ligand. The topological study showed the presence of secondary interactions between the atoms of π-ligands or between atoms of π-ligand and -ligand. It was found that, in the case of titanocenes with small difference in point group symmetry and with bulky ligands, there was an nearly linear relationship between stability and delocalization index involving the ring carbon atoms (Cp) and the titanium. However, the titanocene stability is not only related to the interaction between Ti and C atoms of Cp ring, but secondary interactions also play important role on the stability of voluminous titanocenes. The third chapter deals with the chemical bond in coordination compounds by means of QTAIM. The quantum theory of atoms in molecules so far classifies bonds and chemical interactions in two categories: closed shell interaction (ionic bond, hydrogen bond, van der Waals interaction, etc) and shared interaction (covalent bond). Based on topological parameters such as electron density, Laplacian of electron density, delocalization index, among others, was classified the chemical bond in coordination compounds as an intermediate between closed shell and shared interactions

Contribuições para a detecção e identificação de faltas em inversores Multiníveis

This work presents contributions in the detection and identication of faults in multilevel inverters through the study of the converters behavior under these operation conditions. Basically, the approached fault consists of an open-circuit in any switch of a three-level clamped diode inverter. The converter operation is characterized in the pre and post-fault states. A wave form behavior analysis of the pole voltage, phase current and dc-bus current is also done, which highlights characteristics that allow the detection of failure and, even, under favorable conditions, the identication of the faulty device. A compensation strategy of the approached fault (open-switch) is also investigated with the purpose of maintaining the driving system operational when a failure occurs. The proposed topology uses SCRs in parallel with the internal switches of the inverter, which allows, in some occasions, the full utilization of the dc-bus

Contabilidade do crescimento pelo lado da demanda agregada: uma proposta de cálculo das contribuições ao crescimento pela demanda agregada para o Brasil de, 2000 a 2009, utilizando matrizes insumo-produto

The demand side growth accounting studies the demand aggregate component contributions in the Gross Domestic Product (GDP). Traditionally, international and national organizations that uses the traditional method for calculating such contributions. However, this method does not take into account the effect the induction of imports by the various components of aggregate demand on the calculation of these. As an alternative to this method are presented others studies that consider this effect, as the alternative method proposed by Lara (2013), the attribution method, proposed by Kranendonk and Verbruggen (2005) and Hoekstra and van der Helm (2010), and the method the sraffian supermultiplier, by Freitas and Dweck (2013). Was made a summary of these methods, demonstrating the similarities and differences between them. Also, in the aim to contribute to the study of the subject was developed the “method of distribution of imports” that aims to distribute imports for the various components of aggregate demand, through the information set forth in the input-output matrices and tables of resources and uses. Were accounted the contributions to the growth of macroeconomic aggregates for Brazil from 2001 to 2009 using the method of distribution, and realized comparison with the traditional method, understanding the reasons for the differences in contributions. Later was done comparisons with all the methods presented in this work, between the calculated contributions to the growth of the components of aggregate demand and the domestic and external sectors. Was verified that the methods that exist in the literature was not enough to deal with this question, and given the alternatives for contributions to the growth presented throughout this work, it is believed that the method of distribution provides the best estimates for the account of contributions by aggregate demand sector. In particular, the main advantage of this method to the others is the breakdown of the contribution of imports, separated by aggregate demand component, which allows the analysis of contribution of each component to GDP growth. Thus, this type of analysis helps to study the pattern of growth of the Brazilian economy, not just the theoretical point of view, but also empirical and basis for the decision to economic policies

Computational Tracking of Mental Health in Youth: Latin American Contributions to a Low-Cost and Effective Solution for Early Psychiatric Diagnosis

The early onset of mental disorders can lead to serious cognitive damage, and timely interventions are needed in order to prevent them. In patients of low socioeconomic status, as is common in Latin America, it can be hard to identify children at risk. Here, we briefly introduce the problem by reviewing the scarce epidemiological data from Latin America regarding the onset of mental disorders, and discussing the difficulties associated with early diagnosis. Then we present computational psychiatry, a new field to which we and other Latin American researchers have contributed methods particularly relevant for the quantitative investigation of psychopathologies manifested during childhood. We focus on new technologies that help to identify mental disease and provide prodromal evaluation, so as to promote early differential diagnosis and intervention. To conclude, we discuss the application of these methods to clinical and educational practice. A comprehensive and quantitative characterization of verbal behavior in children, from hospitals and laboratories to homes and schools, may lead to more effective pedagogical and medical intervention
