Relação pedagógica no ensino prático reflexivo como elemento para a formação do enfermeiro na perspectiva da integralidade
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Ciências da Saúde, Programa de Pós-Graduação em Enfermagem, Florianópolis, 2015.Este estudo objetiva compreender como a relação pedagógica no ensino prático-reflexivo, adotada em um curso de graduação em enfermagem, torna-se um elemento para a formação do enfermeiro pautado no princípio da integralidade. Caracteriza-se como um estudo de caso único fundamentado no referencial teórico da epistemologia da prática reflexiva de Donald Allan Schon. A Coleta de dados realizada de maio de 2013 a setembro de 2014 com oito docentes de graduação em enfermagem, mediante análise documental, observação e entrevistas. A análise de dados foi guiada pela proposta operativa de Minayo (2010). Dos resultados emergiram nove categorias: Relação pedagógica: as diferentes maneiras de dizer e ouvir, demonstrar e imitar no contexto da formação do enfermeiro; Combinando o dizer/ouvir e demonstrar/imitar na relação pedagógica; Relação pedagógica e as ferramentas tecnológicas na formação do enfermeiro: universos comportamentais e impasses no ensino- aprendizagem; Aproximação com o contexto profissional: um elemento fértil para conectar teoria e pratica na formação do enfermeiro para a integralidade; reflexão na ação e sobre a ação como elementos potencializadores do ensino da integralidade na relação pedagógica; Talento artístico profissional: habilidades e performances para cuidar na perspectiva da integralidade diante de situações vivenciadas no contexto da prática; ensino-aprendizagem da integralidade em circuito único: consequências para a formação do enfermeiro; relação pedagógica de troca mútua: ensinando e aprendendo a integralidade coletivamente; da aprendizagem em circuito único à aprendizagem em circuito duplo da integralidade: um designer a ser construído pelo professor e estudante no ensino-prático reflexivo. Os resultados apontam que a relação pedagógica no curso pesquisado é um espaço de autonomia, estabelecido pelo diálogo reflexivo com a intencionalidade de (re)construir conhecimentos e de ensinar e aprender. A relação pedagógica ancorada na interação entre teoria e a práticacontribui para um processo de ensino aprendizagem privilegiado pelo fazer, pela capacidade de refletir estimulada pelo docente em diferentes situações do contexto da formação. A relação pedagógica é o elemento que entrelaça o ensino prático reflexivo na formação na perspectiva da integralidade, estabelecida mediante um processo dialógico reflexivo que estimula o estudante a refletir sobre seu próprio processo formativo e sobre o que observa nos serviços de saúde. Esta relação mostrou-se desafiadora no contexto das aulas teóricas, no qual o professor necessita utilizar elementos que despertem o interesse do estudante em estar presente e participativo na aula. O desenvolvimento do talento artístico profissional e do processo reflexivo caracteriza a aprendizagem ancorada no princípio da integralidade através da conexão entre conteúdos teóricos e prática, do diálogo reflexivo entre professor e estudante, da aproximação com o contexto profissional e do ensino-aprendizagem coletivo do princípio da integralidade. A relação pedagógica consolida a formação do enfermeiro no ensino prático reflexivo na perspectiva da integralidade, assim, dependendo do modelo de relação pedagógica estabelecida o estudante tem a oportunidade de refletir sobre suas ações acadêmicas e se construir como um profissional que tenha capacidade de responder a situações incertas e conflituosas da prática.Abstract : This study is aimed at understanding how the pedagogical relationship in the reflective- practical education, adopted in an undergraduate course in Nursing, becomes as an element for the formation of a nurse in the principle of integrality. It is characterized as a single case study based on the theoretical framework of the epistemology of reflective practice of Donald Allan Schon. The data collection was carried out from May 2013 to September 2014 with eight teaching of the nursing department through documentary analysis, observation and interviews. Data analysis was guided by the operative proposal of Minayo (2010). From the results emerged nine categories: pedagogical relationship: the different ways to say and hear, demonstrate and imitate in the context of nursing education; Combining saying/hearing and show/imitate in the pedagogical relationship; Pedagogical relationship and technological tools in nursing education: behavioral universes and impasses in teaching and learning; Approach to the professional context: a fertile element to connect theory and practice in nursing education for integrality; Reflection in action and above the action as elements that potentiates a comprehensive education in the pedagogical relationship; Professional artistic talent: skills and performances to look at the prospect of integration by experienced situations in the context of practice; Teaching and learning of single-loop integrity: implications for nursing education; Pedagogical relationship of mutual exchange: teaching and learning comprehensiveness collectively; From single-loop learning to learning in double circuit of integration: a design to be built by the teacher and the student. The pedagogical relationship in the investigated department is a place of autonomy, established by a reflective dialogue with the intention of (re)building the knowledge and the teaching-learning process. The interaction between theory and practice helps to build a teaching-learning privileged to do for the ability to reflect stimulated by the teacher, in different situations of the contextof training. The educational relationship is the element that weaves reflective practice education in the perspective of comprehensiveness, established through a dialogic process that encourages students to reflect on their own learning process and what you see in health services. This relationship is shown as a challenge in the context of the theoretical classroom where the teacher needs to use elements that arouse student interest in being present and to participate in the classroom. The development of professional artistic talent and reflective learning process characterizes the principle of integration through the connection between theoretical and practical content, reflective dialogue between teacher and student, the approach to the professional context and the collective teaching and learning according to the principle of integrality. The pedagogical relationship strengthens nursing education reflective practice in education in the perspective of integrality, and depending on the model of the established pedagogical relationship, the student has the opportunity, or not, to reflect on their academic actions and act like a professional with the capacity to respond to uncertain and conflicting situations of practice
Manipulating Type-I and Type-II Dirac Polaritons in Cavity-Embedded Honeycomb Metasurfaces
No full textThis is the author accepted manuscript. The final version is available from Springer Nature via the DOI in this recordPseudorelativistic Dirac quasiparticles have emerged in a plethora of artificial graphene systems that mimic the
underlying honeycomb symmetry of graphene. However, it is notoriously difficult to manipulate their properties
without modifying the lattice structure. Here we theoretically investigate polaritons supported by honeycomb
metasurfaces and, despite the trivial nature of the resonant elements, we unveil rich Dirac physics stemming
from a non-trivial winding in the light-matter interaction. A new kind of type-II Dirac point emerges which
simultaneously exists with its conventional type-I counterpart. By modifying only the photonic environment
via an enclosing cavity, one can manipulate the location of the type-II Dirac points, leading to distinct polariton
phases. This enables one to alter the fundamental properties of the emergent Dirac polaritons while preserving
the lattice structure—a unique scenario which has no analog in real or artificial graphene systems so far.
Exploiting the photonic environment will thus give rise to unexplored Dirac physics at the subwavelength scale.C.-R.M. and T.J.S. acknowledge financial support

1.57 Ga protolith age of the Neoproterozoic Forquilha eclogites, Borborema Province, NE-Brazil, constrained by UePb, Hf and Nd isotopes
No full textFAPESP - FUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULOThe 30km-long, N-S-trending Forquilha eclogite zone, occurs within a Paleoproterozoic block mainly composed of gneisses and migmatites, in the Ceará Central domain, Borborema Province, NE Brazil. The Forquilha eclogite zone contains lenses of high to ultra-high pressure metamafic rocks, found as granulites and amphibolites associated with kyanite-sillimanite gneisses. Three samples of clinopyroxene-garnet amphibolite yielded the U-Pb zircon ages of 1566±9Ma, 1547±37Ma and 1532±24Ma, interpreted as the timing of igneous crystallization of the mafic protolith. Additionally, zircon grains of a leucocratic layer of a metamafic rock and a retrograded eclogite provided the less precise U-Pb ages of 1613±40Ma and 1454±120Ma, respectively. Lu-Hf and Sm-Nd model ages provided TDM (Hf) between 1.55 and 1.81Ga with positive εHf values of+7.50 to+10.48, and TDM (Nd) ranging between 1.57 and 1.92Ga with positive εNd values of+1.84 to+4.36. It is believed that part of the rocks of the Forquilha eclogite zone were emplaced as mafic dikes in an extensional setting at ca. 1.57Ga.58210222FAPESP - FUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULOFAPESP - FUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULO07/58535-6; 03/07663-3Albarede, F., Telouk, S., Blichert-Toft, J., Boyet, M., Agranier, A., Nelson, B., Precise and accurate isotopic measurements using multiple-collector ICPMS (2004) Geochimica Cosmochimica Acta, 68, pp. 2725-2744Almeida, F.F.M., Hasui, Y., Brito Neves, B.B., Fuck, R.A., Brazilian structural provinces: an introduction (1981) Earth Sci.

The impact of HIV exposure and maternal Mycobacterium tuberculosis infection on infant immune responses to bacille Calmette-Guérin vaccination.
No full textOBJECTIVE: The objective of this study is to assess the effect of maternal HIV and Mycobacterium tuberculosis (Mtb) infection on cellular responses to bacille Calmette-Guérin (BCG) immunization.
DESIGN: A mother-infant cohort study.
METHODS: Samples were collected from mother-infant pairs at delivery. Infants were BCG-vaccinated at 6 weeks of age and a repeat blood sample was collected from infants at 16 weeks of age. BCG-specific T-cell proliferation and intracellular cytokine expression were measured by flow cytometry. Secreted cytokines and chemokines in cell culture supernatants were analysed using a Multiplex assay.
RESULTS: One hundred and nine (47 HIV-exposed and 62 HIV-unexposed) mother-infants pairs were recruited after delivery and followed longitudinally. At birth, proportions of mycobacteria-specific proliferating T cells were not associated with either in-utero HIV exposure or maternal Mtb sensitization. However, in-utero HIV exposure affected infant-specific T-cell subsets [tumour necrosis factor-alpha (TNF-α) single positive proliferating CD4⁺ T cells and interferon-gamma (IFN-γ), TNF-α dual-positive CD4⁺ T cells]. Levels of TNF-α protein in cell culture supernatants were also significantly higher in HIV-exposed infants born to Mtb-sensitized mothers. In the presence of maternal Mtb sensitization, frequencies of maternal and newborn BCG-specific proliferating CD4⁺ T cells were positively correlated. Following BCG vaccination, there was no demonstrable effect of HIV exposure or maternal Mtb infection on infant BCG-specific T-cell proliferative responses or concentrations of secreted cytokines and chemokines.
CONCLUSION: Effects of maternal HIV and Mtb infection on infant immune profiles at birth are transient only, and HIV-exposed, noninfected infants have the same potential to respond to and be protected by BCG vaccination as HIV-unexposed infants
Unraveling the essential effects of flocculation on large-scale sediment transport patterns in a tide-dominated estuary
No full textAbstract: Sediment transport in estuaries and the formation of estuarine turbidity maxima (ETM) highly depend on the ability of suspended particulate matter (SPM) to flocculate into larger aggregates. While most literature focuses on the small-scale impact of biological flocculants on the formation of larger aggregates, the influence of the flocculation process on large-scale estuarine SPM profiles is still largely unknown. In this paper, we study the impact of flocculation of SPM on the formation of ETM. For this, a semianalytical width-integrated model called iFlow is utilized and extended by a flocculation model. Starting from a complex one-class flocculation model, we show that flocculation may be described as a linear relation between settling velocity and suspended sediment concentration to capture its leading-order effect on the ETM formation. The model is applied to a winter case in the Scheldt estuary (Belgium, Netherlands) and calibrated to a unique, long-term, two-dimensional set of turbidity (cf. SPM) observations. First, model results with and without the effect of flocculation are compared, showing that the spatial and temporal variations of the settling velocity due to flocculation are essential to reproduce the observed magnitude of the suspended sediment concentrations and its dependence on river discharge. Second, flocculation results in tidally averaged land-inward sediment transport. Third, we conduct a sensitivity analysis of the freshwater discharge and floc breakup parameter, which shows that flocculation can cause additional estuarine turbidity maxima and can prevent flushing of the ETM for high freshwater inflow
Conhecimento e uso das plantas pelos Xokleng na TI Ibirama-Laklãnõ, Santa Catarina
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Ciências Biológicas, Programa de Pós-Graduação em Biologia de Fungos, Algas e Plantas, Florianópolis, 2014.O escopo da etnobotânica envolve o estudo do uso das plantas em seu contexto social. O presente trabalho objetivou registrar o conhecimento e uso das plantas pelos Xokleng na TI (Terra Indígena) Ibirama Laklãnõ, na região do vale do Itajaí, estado de Santa Catarina. Os Xokleng pertencem à família linguística Jê, foram contatados em 1914 e restritos a uma reserva para evitar conflitos no processo de colonização da Região Sul. A partir de então passaram por diversas adaptações e mudanças em seu modo de vida. Atualmente esta população é a única remanescente dos Xokleng que vive ainda numa organização sociopolítica unitária, por isso sendo fundamental o registro e a valorização de seu conhecimento. A pesquisa foi realizada em duas das oito aldeias da TI, que possuem diferentes condições de altitude, clima e vegetação, e diferentes trajetórias históricas (aldeias Bugio e Sede). Após a obtenção da anuência prévia, foram realizadas 112 entrevistas com os adultos para registrar dados socioeconômicos e realizar uma listagem livre das plantas conhecidas e utilizadas. As plantas foram coletadas em turnês guiadas para identificação botânica. Foram registradas 314 plantas, utilizadas principalmente para alimentação (35%) e com fins medicinais (29%), mas também para artesanato (13%), construção (10%) ferramentas/utilitários (6%) uso simbólico (1%) e outros usos (3%). As principais partes das plantas por eles utilizadas são: caules (29%), seguidos pelas folhas (24%) e frutos (20%). As plantas mais citadas foram: batata doce (Ipomoea batatas (L.) Lam.), laranja (Citrus sp.), eucalipto (Eucaliptus sp.), vara-de-cutia (E.grandiflora), aipim (Manihot esculenta Crantz,) salvação-da-senhora (Mollinedia spp.) e a gabiroba (Campomanesia xanthocarpa Mart. ex O. Berg. ). A maioria das plantas é espontânea (59%) e 41% é cultivada. Apesar da existência de atividades de obtenção de alimento praticadas pelas unidades familiares como cultivo de hortas, roças, coleta de plantas, caça e pesca, grande parte da renda das famílias é destinada à alimentação. Das plantas citadas: 77% são de uso atual, 15% são de uso passado e 8% são apenas conhecidas pelos informantes, mas não usadas. Na análise da distribuição do conhecimento os homens citaram mais plantas do que as mulheres, para as categorias construção, lenha e ferramentas/utilitários, as quais estão relacionadas à extração madeireira, o que se assemelha ao padrão encontrado para colonos de descendência europeia nessa mesma região. Não há correlação entre a distribuição do conhecimento e a idade, mas com base nos dados etnográficos foi possível perceber a influência das famílias que valorizam e praticam a cultura Xokleng no conhecimento individual. A transmissão do conhecimento, analisada para as categorias de uso medicinal e artesanato, mostrou-se centrada na família, ocorrendo principalmente entre gerações e durante a infância. As redes de transmissão evidenciam a posição central dos mais velhos, como núcleos irradiadores de conhecimento para suas famílias. Percebemos duas forças atuando sobre o conhecimento e a cultura Xokleng: de um lado a influência da sociedade não índia e do outro a resistência do povo Xokleng ao valorizar sua cultura. Apesar de todas as mudanças que a cultura Xokleng passou devido à influência da sociedade envolvente, percebe-se que eles ainda possuem uma forte ligação com seu território e os recursos naturais, pois conhecem e usam muitas plantas no seu dia a dia. Essa constatação somada à necessidade de garantir a sustentabilidade dos povos são motivos importantes para se discutir a ampliação das terras indígenas principalmente na região sul, onde elas são menores e onde as populações indígenas estão em crescimento. Finalmente, a partir dos dados registrados sobre as plantas conhecidas e usadas, e sob uma perspectiva de pensar a conservação através do uso, apontam-se algumas alternativas que possam ajudar na garantia de sustento das famílias Xokleng e na conservação ambiental da TI Ibirama Laklãnõ.Abstract : The scope of ethnobotany research involves the study of the use of plants in their social context. The present study aimed to record the knowledge and use of plants by the Xokleng tribe in Indigenous Land Ibirama-Laklãnõ, in the Itajaí River Valley, in the state of Santa Catarina, Brazil. The Xokleng people, who belong to the Jê linguistic family, were contacted in 1914 and restricted to a designed area to avoid conflicts in the Southern Region colonization process. From then on they endured several adaptations and changes in their livelihood. Currently, this group is the only remaining Xokleng community that still lives in a unitary socio-political organization, therefore recording and valuing their knowledge is fundamental. The survey was conducted in two of the eight villages of the indigenous land, which have different conditions of altitude, climate and vegetation, in addition to different historical trajectories. After obtaining prior consent from the community leaders, 112 interviews were conducted with adults to register socioeconomic data and perform a free listing of known and used plants. Plants were collected during guided tours for further identification. A total of 314 plants were recorded, used primarily for food (35%) medicinal purposes (29%), handicrafts (13%), construction (10%) tools/utilities (6%) symbolic uses (1%) and other uses (3%). The main parts of the plants used by them are trunks (29%), followed by leaves (24%) and fruits (20%). The most mentioned plants were: sweet potatoe (Ipomoea batatas (L.) Lam.), orange (Citrus sp.), (Eucalyptus sp.), (E.grandiflora), (Manihot esculenta Crantz,) (Mollinedia spp.) and (Campomanesia xanthocarpa Mart. ex O. Berg. )Most plants grow spontaneously (59%) and 41% are cultivated. Despite the activities developed by the family units for obtaining food such as cultivating crops in gardens and small fields, collecting plants, hunting and fishing, much of their income is used for food. Among the mentioned plants, 77% are currently being used, 15% are from past use and 8% are only known by the participants, but not used. Analyzing knowledge distribution, men cited more plants than women, for construction, firewood, tools/utilities, categories related to logging, which resembles the pattern found for settlers of European descent in the same region. There is no correlation between the distribution of knowledge and age, but based on ethnographic data, it was possible to note the influence of families on individual knowledge, since people who demonstrated greater knowledge of the plants came from families where the Xokleng culture is valued and practiced. The analysis of the transmission of knowledge related to plants for medicinal and crafts use, proved it to be family-centered, intergenerational, and mostly occurring during childhood. The transmission-of-knowledge networks show the central position of the older generation as knowledge core transmitters for their families. Thus, we see two forces acting on the Xokleng knowledge and culture: on one hand the influence of the non-indigenous society and on the other, the strength of the Xokleng people determined to cherish their culture. Despite all changes the Xokleng culture went through due to the influences of the surrounding society, they still have a strong connection with their territory and natural resources, as they know and use plants in their daily lives. The above statement as well as the need to ensure the sustainability of indigenous people, leads to the serious discussion of expanding the Indigenous lands, mainly in the southern region of Brazil, where the lands are reduced and where indigenous populations are growing. Finally, from the data recorded on known and used plants, and from a perspective of thinking about conservation through sustainable use, some alternatives that can help ensuring livelihood of Xokleng families and the conservation of Indigenous Land Ibirama-Laklãnõ are pointed out

This article may be used for non-commercial purposes in accordance with Wiley Terms and Conditions for Self-Archiving.[EN] Lasiodiplodia theobromae is one of the most frequent fungal pathogens associated with dieback, gummosis, leaf spot, stem-end rot and fruit rot symptoms in cashew, mango, papaya and grapevine. In this study, the variation in the genetic diversity of 117 L. theobromae isolates from northeastern Brazil (n = 100) and Mexico (n = 17), which were collected from these four crops, was analysed using microsatellite markers. The results revealed low genetic diversity among L. theobromae populations and the existence of two genetic groups. All Mexican isolates were grouped with Brazilian isolates, suggesting a low level of differentiation between these populations. Furthermore, no evident host or climate-based population differentiation was observed for L. theobromae in Brazil. The populations studied were mostly clonal, but additional studies are needed to better understand the mode of reproduction of the pathogen. The low genetic diversity of L. theobromae populations in northeastern Brazil suggests that resistant cultivars could be used as a durable management strategy to reduce the impact of the diseases caused by this pathogen.This study was financially supported by CoordenacAo de Aperfeicoamento de Pessoal de Nivel Superior - CAPES, 'Ciencia sem Fronteiras - CAPES' (number 88881.132070/2016-01) and the Universitat Politecnica de Valencia.
