The aim of this study was to investigate the genetic variation, the genotype × soil interaction and the selection among and within Corymbia citriodora progenies in three different kinds of soils (Red Latossol, Quartz Sand and Purple Latossol), which occur in the Luiz Antônio Experimental Station, São Paulo State, Brazil. The progeny test was established 1983, using 56 open-pollinated families of C. citriodora. Twenty fve years after planting the following traits were measured: height, diameter at breast height (Dbh), stem form and survival. Best growth occurred in Purple Latossol. Significant differences among progenies were detected for most traits in all sites, suggesting the possibility of improvement by selection. In the analysis with sites, Significant differences among locals, progenies and genotypes × soil interaction were detected, confiming that the tested material has sufficient genetic variation to be explored by selection in all sites. The analysis of genotype × soil interaction indicates that growth traits present single interaction and the same progenies can be selected in each site. On the order hand, genotype × soil interaction for stem form and survival was complex; and specifc progenies need to be selected for each kind of soil. The population, due to its high genetic variation and strong genetic control of traits, permits to obtain considerable genetic gains by selection among and within progenies.

The aims of this study were to evaluate the variation and to estimate genetic parameters for silvicultural anatomic wood traits for genetic breeding of a Myracrodruon urundeuva (Engler) Fr. Allem, population from Selvíria-MS. For this, from samples of a progeny test established in the Fazenda de Ensino, Pesquisa e Extensão da Faculdade de Engenharia de Ilha Solteira/UNESP, macroscopic anatomic wood traits of M. urundeuva (tangential diameter and vases frequency per mm2) and growth traits were measured (height, DBH and stem form). Genetic parameters were estimated in 28 open-pollinated progenies, in three replications and 10 plants per plot, using a REML/BLUP approach. Between the analysed traits, the DBH is the most indicated for selection for timber production, because it presented the highest values of coefficient of genetic variation, heritabilities and selective accuracy. Between the anatomic traits, the vessels frequency in the pith showed the highest values for genetic parameters. For pulp yield, based on the multi-effect index, the strategy of selecting the best trees for vessels frequency in the pith, independent of the progeny, permitted to obtain substantial gains by mass selection, without progeny test.

The aim of this study was the selection of Corymbia citriodora provenances for three different kinds of soils occurring in Luiz Antônio Experimental Station, São Paulo, Brazil (Latossolo Vermelho, Areia Quartzosa and Latossolo Roxo). The provenance test was established in 1983, with ten Corymbia citriodora provenances and one Eucalyptus grandis as control, original from a seed production area. The trials were established in a random block design with 11 treatments, three repetition and square plots with 25 trees. In 2008, there were evaluations of height, diameter at breast height (DBH, 1.3 m), stem form and survival. Significant differences among soils and provenances were detected for the growth traits, stem form and survival in all those studied soils. Significant provenance and soil interactions were not detected. All provenances showed higher growth in height and DBH in Purple Latosol. The control had a higher growth rate in relation to highness, DBH and stem form than Corymbia citriodora provenances in all the studied soils, but it presented, generally, a lower survival rate than Corymbia citriodora provenances. Pederneiras (11) Corymbia citriodora provenance presented a higher performance in relation to highness and DBH in all kinds of soils, and Gilgandra (4) provenance, original from Australia, had the worst development. Therefore, Pederneiras (11) provenance is, therefore, the best choose for reforestations in all those studied soils.

Eucalyptus urophylla S. T. Blake is outstanding for valuable wood production potential, adaptation plasticity for different environmental conditions, and for tolerance to canker. However, genetic improvement of this specie in Brazil depends on the existence of genetic variability in the introduced populations. The objective of this study was to investigate the genetic variation and gains in quantitative traits in a population established in 1992 in Selvíria - MS. The progeny trial was established in a partially balanced, 8 x 8 lattice design, with 64 families, collected at Anhembi Experimental Station (IPEF/ESALQ/USP). Each plot was made up of eight trees planted in a 3 × 3 m spacing. Significant among families genetic variations were observed in diameter at breast height (DBH), bark type, stem form, and survival. Estimates of average family heritability were high for all traits, ranging from 0.50 to 0.85. The simulated selection by using multi-effect index showed that under a varying number of plants per family. This method is the most indicated to maximize genetic gains (7.24%) and the effective population size (69.3). These results are a useful support for the transformation of this test into a seedling seed orchard and to become a source of vegetative material to build a clonal seed orchard.

Anthropogenic changes in the reproductive population density can affect the mating system and result in an increase in selfing and correlated matings. This study investigated the mating system in small fragmented populations of the insect pollinated tropical tree species Copaifera langsdorffii, using microsatellite loci and the mixed and correlated mating models. Open-pollinated seeds were collected from 15 seed-trees located in a small forest fragment (4.8 ha), denominated Bosque and from 14 other seed-trees located in other small forest fragments of the north-western region of São Paulo State. No significant differences were observed between the seed-trees from Bosque (tm=0.933±0.028) and other fragments (tm=0.971±0.032), although these estimates were significantly different from 1.0, suggesting that selfing was occurring. Differences between multilocus and unilocus outcrossing rate were significantly high in both seed-trees of Bosque (tm -ts=0.478±0.05) and other forest fragments (tm -ts=0.475±0.018), suggesting a spatial genetic structure in those stands. The results also showed high rates of correlated mating in the samples, indicating that a good part of the offspring were full-sibs. As a consequence of selfing, mating among relatives and correlated matings, the coancestry within families was equally high in the seed-trees of Bosque ((Θ=0.237) and in the seed-trees of the other forest fragments (Θ=0.241) and the effective population size was lower than expected in panmitic populations (Ne<4). The results were discussed, focusing on the sample size of seed-trees to collect seeds for genetic conservation and enviromental reforestation.

Intensive deforestation and forest fragmentation of the Brazilian forest biomes has contributed to increase the number of trees species under the risk of extinction. Peltophorum dubium (Sprengel) Taubert is one of these species. Some of its populations are being conserved ex situ by the Instituto Florestal de São Paulo through provenance and progeny tests. The aim of this study was to investigate the genetic variation and to estimate genetic parameters at age 24 years in a progeny test of P. dubium established in Luiz Antônio, São Paulo State, Brazil. The trial was established in a random block design, with six replications, five plants per plot and 18 open-pollinated progenies. Measured were: diameter at breast height (DBH), height and stem form. The genetic parameters heritability, genetic variation and effective population size were estimated. Significant genetic differences were observed only for DBH. This trait also presented a high coefficient of genetic variation (CV g=4.8%) and heritability, especially among progeny means (h m 2=0.6607). This indicates that DBH is the most indicated trait for selection in the population. The effective population size conserved ex situ in the test was estimated to be 38.9. Concerning genetic conservation, although the effective population size in the test is small, the values of the genetic variation and of the heritability indicate that the ex situ population has sufficient genetic variation and potential to respond to changes promoted by natural and artificial selection.

This study has investigated the genetic variation for silvicultural traits in an open-pollinated progeny test of Astronium graveolens Jacq., established at Luiz Antônio Experimental Station (State of São Paulo, Brazil). The trial was planted in a random block experimental design, containing 23 families, six replications and five plants per plot. The traits measured were diameter at breast height (DBH), total height and stem form. The assessments were taken at the age of 19 years. Significant differences were not detected by the analysis of variance, suggesting that the genetic variation was low, as well as the probability to raising genetic gains through selection among progenies. The coefficient of genetic variation was moderate for the traits height (8.2%) and DBH (21.2%) and low to stem form (4.0%). However, the average coefficient of heritability among progenies was low for all studied traits (ranging from 0.02 to 0.15), confirming the low probability of genetic improvement of this population by selection among progenies.

This work consists of a semiotic analysis of the animation motion picture The Lion King (1994), by the Walt Disney Animation Studios, describing its intertextual relation with Hamlet, by Shakespeare, considering Disney’s individuality, its style. In order to study style in texts, we use discursive semiotics theory, highlighting Discini’s work (2013) and the concept of discursive settings. Hence, a deep discussion about The Lion King’s style, compared to the Shakespeare’s play, is established. The movie, once a syncretic text, requires advanced studies on Expression Plane, its plastic, musical and verbal/phonic aspects. We find these studies in the work of José Luiz Fiorin (2009), Lúcia Teixeira (2009), Ana Claúdia de Oliveira (2009), Jean-Marie Floch (2009) and Antônio Vicente Pietroforte (2008). We note how a syncretic text makes the discursive settings more complex by assembling plastic and sonorous materials in semissimbolic relation. Once defined The Lion King’s style, we analyze the way it justifies the intense popularity of this kind of animation features. Finally, it is important to understand how Disney uses in its style not only discursive settings, but also passional settings, revealing its own way to stir emotions on the spectator

O objetivo dessa tese é aprofundar, a partir do discurso pós-colonial, uma crise na perspectiva teológica da libertação. Esta promoveu, na década de 1970, uma reviravolta nos estudos teológicos no terceiro mundo. Para tanto, leremos um conto de Gabriel García Márquez chamado “El ahogado más hermosodel mundo” (1968) analizando e avaliando as estratégias políticas e culturais ali inscritas. Para levar a frente tal avaliação é preciso ampliar o escopo de uma visão que divide o mundo em secular/religioso, ou em ideias/práticas religiosas e não religiosas, para dar passo a uma visão unificada que compreende a mundanalidade, tanto do que é catalogado como ‘religioso’ quanto do que se pretende ‘não religioso’. A teologia/ciências da religião, como discurso científico sobre a economia das trocas que lidam com visões, compreensões e práticas de mundo marcadas pelo reconhecimento do mistério que lhes é inerente, possuem um papel fundamental na compreensão, explicitação, articulação e disponibilização de tais forças culturais. A percepção de existirem elementos no conto que se relacionam com os símbolos sobre Jesus/Cristo nos ofereceu um vetor de análise; entretanto, não nos deixamos limitar pelos grilhões disciplinares que essa simbologia implica. Ao mesmo tempo, esse vínculo, compreendido desde a relação imperial/colonial inerente aos discursos e imagens sobre Jesus-Cristo, embora sem centralizar a análise, não poderia ficar intocado. Partimos para a construção de uma estrutura teórica que explicitasse os valores, gestos, e horizontes mundanos do conto, cristológicos e não-cristológicos, contribuindo assim para uma desestabilização dos quadros tradicionais a partir dos quais se concebem a teologia e as ciências da religião, a obra de García Márquez como literatura, e a geografia imperial/colonial que postula o realismo ficcional de territórios como “América Latina”. Abrimos, assim, um espaço de significação que lê o conto como uma “não-cristologia”, deslocando o aprisionamento disciplinar e classificatório dos elementos envolvidos na análise. O discurso crítico de Edward Said, Homi Bhabha e GayatriSpivak soma-se à prática teórica de teólogas críticas feministas da Ásia, da África e da América Latina para formular o cenário político emancipatório que denominaremos teologia crítica secular.

Vivemos um tempo de mudança de paradigmas na educação. O advento da sociedade em rede nesta Era Digital está a transformar profundamente a sociedade e a educação. De um ensino industrial e de cariz comportamentalista, assistimos hoje à emergência de um ensino pós-industrial e de índole construtivista. A distinção entre o ensino presencial e o ensino online é cada vez menor, requerendo o desenvolvimento de competências digitais por parte de professores e alunos. Torna-se necessária a construção de uma identidade digital que não é apenas uma identificação do estudante, mas é a sua marca digital enquanto cidadão.

O Staphylococcus aureus resistente a meticilina (MRSA) foi inicialmente descrito como um patógeno associado a infecções relacionadas à assistência em saúde; porém, um clone de MRSA, o CA-MRSA emergiu na comunidade e está atualmente incrementando nos hospitais. O objetivo desta tese foi descrever aspectos relacionados com a epidemiologia das infecções por cepas CA-MRSA no Hospital Universitário Pedro Ernesto da Universidade do Estado do Rio de Janeiro (HUPE/UERJ), avaliando especificamente fatores de risco relacionado com as infecções por CA-MRSA. Usando informações das bases de dados do laboratório de microbiologia, da farmácia e da Comissão para Controle da Infecção Hospitalar do HUPE/UERJ foi realizado um estudo retrospectivo de infecções/colonizações por cepas de S. aureus (fevereiro 2005 a Julho 2011). Foi realizado um estudo caso e controle, utilizando como casos os pacientes com infecções por cepas CA-MRSA. Na avaliação da susceptibilidade aos antimicrobianos usados em infecções graves por MRSA (vancomicina, teicoplanina, daptomicina e linezolida), foram determinadas as concentrações inibitórias mínimas (CIM) das amostras por diferentes metodologias (testes de difusão em agar, microdiluição em caldo e E-test). Nas analises das tendências temporais da apresentação dos subtipos de MRSA, usando um critério fenotípico para classificação das cepas MRSA, foi observada uma diminuição do número de cepas de MRSA multirresistente (HA-MRSA) (p<0.05). Também foi observada uma tendência ao aumento de cepas não-multirresistentes (CA-MRSA), mas sem alcançar a significância estatística (p = 0.06) igual que os S. aureus sensíveis a meticilina (MSSA) (p = 0.48). Não houve associação entre o subtipo de MRSA e a mortalidade devida à infecção por cepas MRSA. Uma idade acima de 70 anos (OR: 2.46, IC95%: 0.99 - 6.11), a presença de pneumonia adquirida no hospital (OR: 4.94, IC95%: 1.65 -14.8), a doença pulmonar obstrutiva crônica (OR: 6.09, IC95% 1.16 31.98) e a leucemia (OR: 8.2, IC95%: 1.25 54.7) foram fatores de risco associadas à mortalidade nas infecções por cepas de S. aureus. Usando curvas de Kaplan-Meier, foi observada uma tendência ao aumento da mortalidade em infecções causadas por MSSA na primeira semana, porém sem alcançar significância estatística (p = 0.07). Não foram observadas amostras MRSA com susceptibilidade intermediaria a vancomicina, linezolida, daptomicina ou teicoplanina. A dinâmica das infecções por S. aureus no HUPE/UERJ mudou durante o período de estudo, com menor número de episódios infecciosos causados por cepas de MRSA multirresistentes. Existe uma tendência ao aumento das cepas não-multirresistentes de MRSA entanto que a taxa de infecções por MSSA permaneceu estável no período do estudo. O perfil de resistência dos estafilococos não teve associação com a mortalidade
