A METALINGUAGEM NO VIDEOCLIPE: O uso dos signos no discurso audiovisual

Com o objetivo de verificar se o videoclipe é uma maneira de reafirmar o discurso apresentado na música, ele foi subdividido em sete sequências, que tiveram suas cenas transcritas e analisadas de forma individual a fim de identificar signos e processos metalinguísticos que foram utilizados para produzir o sentido  do discurso apresentado pela banda Queen. Dividindo a análise em três seções, a primeira seção se dedicou exclusivamente à identificação e classificação dos signos presentes no videoclipe. Em seguida, na segunda seção, foram apresentados os processos metalinguísticos de autorreferência, presentes na crítica da banda à características específicas do rádio e da televisão. Na terceira e última seção, os signos identificados e os processos metalinguísticos apresentados foram utilizados para remontar o percurso gerativo de sentido e os processos de significação do videoclipe da música Radio Ga Ga.Os resultados da análise mostraram que os signos e seus significados se referem a várias características das mídias rádio e televisão, mostrando-se nas categorias de ícone e indice na forma de representaçõs metafóricas

Canopy cover and invasive grasses effects in distinct ecological restoration technologies: 5-y monitoring in a Brazilian subtropical forest

The establishment of canopy and the following elimination of invasive exotic grasses are among the main barriers towards the restoration of subtropical forests. We compared canopy initial cover and biological invasion by exotic grasses in different restoration technologies, up to 5-y, in Paraná State, southern Brazil. We tested three treatments in four randomized blocks as follows: T1 – passive restoration; T2 – nucleation; and T3 – high diversity plantation. We sampled 117 points per plot (54 x 40 m). We registered the presence or absence of invasive grasses cover and canopy cover percentage (using a spherical crown densiometer). The high density of fast-growing trees plus dense crowns was probably responsible for the highest shadowing and faster elimination of grasses in the plantation, while nucleation and the passive restoration showed the lowest canopy cover followed by the highest invasion by grasses. We recommend managers to use plantations to make a fast covering, although with higher inputs, or use nucleation in a long-term shadowing basis project

Fuentes de autoeficacia en profesores

Teacher's self-efficacy is the judgment that teachers make about their own ability and skills in teaching, even in unfavorable conditions. A teacher's sense of efficacy can be influenced by four sources of information: mastery experience, vicarious experience, verbal or social persuasion, and emotional and physiological factors. This study aims to characterize basic education teachers, considering the indexes of the self-efficacy sources, sociodemographic aspects (like age, sex and education level of teachers), and teaching activity (working time and period of time). A total of 495 basic education teachers, who work in a private confessional network of schools in the states of Pará, Maranhão and Amapá (Brazil) participated in this study, from January to July 2014. As data collection, researchers used the Participant Characterization Survey (Questionário de Caracterização do Participante) and the Teacher Self-Efficacy Sources Scale (Escala de Fontes de Autoeficácia de Docentes). The statistical techniques used were factorial analysis and correspondence analysis. The results indicated that there was a significant association among the four sources of self-efficacy. There was a correlation between verbal persuasion and length of service and function. From the sociodemographic characteristics investigated, only age has been correlated to emotional and physiological factors. There was no association between age and the others sources.      La autoeficacia docente es la opinión que los profesores tienen sobre su propia capacidad y habilidades de enseñanza, aún en condiciones no favorables. Está constituida a través de cuatro fuentes de información: experiencia de dominio, experiencia vicaria, persuasión verbal o social, y estados afectivos y fisiológicos. Este estudio tuvo como objetivo caracterizar docentes de educación básica, considerando los índices de las fuentes de autoeficacia, los aspectos sociodemográficos (como edad, sexo y el nivel de educación de los profesores) y actividad docente (tiempo de trabajo y periodo de trabajo). Participaron en esta investigación 495 profesores de una red privada de escuelas confesionales de educación básica, en los estados de Pará, Maranhão y Amapá (Brasil), en el periodo de enero a julio del 2014. Para la recolección de los datos, fueron utilizados el Cuestionario de Caracterización del Participante (Questionário de caracterização do Participante) y la Escala de Fuentes de Autoeficacia Docente (Escala de Fontes de Autoeficácia de Docentes). Las técnicas estadísticas utilizadas fueron análisis factorial y análisis de correspondencia. Los resultados indicaron que hubo asociación significativa entre las cuatro fuentes de autoeficacia. Hubo correlación entre la persuasión verbal y la duración del servicio y función. De los aspectos sociodemográficos investigados, solo la edad fue correlacionada a los estados afectivos y fisiológicos. No hubo asociación de la edad con las demás fuentes.   &nbsp

Proteomic analysis of the ventral disc of Giardia lamblia

<p>Abstract</p> <p>Background</p> <p><it>Giardia lamblia </it>is a multiflagellated protozoan that inhabits the small intestine of vertebrates, causing giardiasis. To colonize the small intestine, the trophozoites form of the parasite remains attached to intestinal epithelial cells by means of cytoskeletal elements that form a structure known as the ventral disc. Previous studies have shown that the ventral disc is made of tubulin and giardins.</p> <p>Results</p> <p>To obtain further information on the composition of the ventral disc, we developed a new protocol and evaluated the purity of the isolation by transmission electron microscopy. Using 1D- and 2D-PAGE and mass spectrometry, we identified proteins with functions associated with the disc. In addition to finding tubulin and giardin, proteins known to be associated with the ventral disc, we also identified proteins annotated in the <it>Giardia </it>genome, but whose function was previously unknown.</p> <p>Conclusions</p> <p>The isolation of the ventral disc shown in this work, compared to previously published protocols, proved to be more efficient. Proteomic analysis showed the presence of several proteins whose further characterization may help in the elucidation of the mechanisms involved in the attachment of the protozoan to epithelial cells.</p

Genetic parameters and predicted gains with selection of interspecific hybrids of Paspalum for seed production

The aim of this study was to estimate the genetic parameters and predicted gains with selection of interspecific hybrids of Paspalum in relation to seed production traits Data were analyzed in randomized block design, with 23 genotypes arranged into ten blocks, according to the methodology of mixed models by the REML/BLUP procedure. The traits considered in the study were: number of total tillers/plant, number of reproductive tillers/plant, number of racemes/inflorescence, number of seeds/inflorescence, weight of a thousand seeds and seed production. Variability among genotypes, high heritability (>0.50), except total tillers (0.44) and number of racemes (0.36), and high accuracy (>0.90) were identified for all traits. The hybrids 10E5052, 10E4026, 10E507, 10E4025 and 10E40104 are among the top ten because they have high genetic values in three or more traits, indicating that these genotypes should be recommended for direct use in planting or potential parents to be used in new crosses

Objetivo: Analisou-se a evolução do brincar em bebês com e sem risco psíquico e sua relação com o desenvolvimento infantil de nove aos 24 meses. Estudo quantitativo, observacional, retrospectivo. Método: A obtenção dos dados foi através do roteiro de análise do brincar, elaborado nesta pesquisa. Foram observados os aspectos cognitivos do brincar do bebê, a relação intersubjetiva e análise do investimento materno. Avaliaram-se 32 bebês e suas mães. Foram utilizados os indicadores clínicos do desenvolvimento infantil e os sinais PREAUT para detecção do risco psíquico. Resultados: Houve associação significativa no prazer da criança em relação ao risco na experiência com o objeto, bem como o prazer e empenho maternos no brincar. Com relação ao uso criativo do objeto nas crianças com risco aparece mais tardiamente do que no grupo sem sofrimento psíquico, aos 18 meses. Conclusão: As crianças com sofrimento psíquico e suas mães apresentaram menos construções criativas em relação às sem sofrimento

Influência de porta-enxertos no crescimento de clones de seringueira no Estado de São Paulo

This paper was established in the experimental fields of Estação Experimental de Agronomia de Pindorama, SP, Brazil, in order to evaluate rootstocks vs. scion interaction in rubber tree, Hevea brasiliensis (Willd. ex Adr de Juss.) Müell. Arg. The clones involved were: IAN 873, RRIM 600, RRIM 701, PB 235, PR 107 and GT 1 grafted in six different rootstocks from illegitimate seeds of the clones IAN 873, RRIM 600, RRIM 701, PB 235, GT 1 and from unselected seeds. The lay out used was that of randomized blocks in split-splot design, with four replications. The outcome has shown that in the evaluation period the GT 1 and IAN 873 rootstocks were the ones which produced the mayor girth per plant, being 10.20% larger than that of unselected seeds. At the same time the clones studied pointed out that PB 235, RRIM 600 and PR 107 had a better achievement with an increase of 8.12% in the stem girth compared with RRIM 701 and GT 1 clones that had the worst development. The interaction rootstocks vs. scion was not significant.Este trabalho foi instalado na Estação Experimental de Agronomia de Pindorama, SP, com a finalidade de avaliar a interação enxerto vs. porta-enxertos de seringueira, Hevea brasiliensis (Willd. ex Adr. de Juss.) Müell. Arg. Os clones utilizados foram IAN 873, RRIM 600, RRIM 701, PB 235, PR 107 e GT 1, enxertados em seis diferentes porta-enxertos provenientes de sementes ilegítimas dos clones IAN 873, RRIM 600, RRIM 701, PB 235, GT 1 e de sementes não selecionadas. O delineamento utilizado foi o de blocos ao acaso, com parcelas subdivididas, tendo os porta-enxertos como tratamentos e os clones (enxertos) como subtratamentos, em quatro repetições. Os resultados mostram que no período de avaliação o porta-enxerto GT 1 e IAN 873 foram os que produziram os maiores perímetros por planta, sendo 10,20 % maior que o de sementes não selecionadas. Paralelamente, os enxertos em vigor mostraram que os clones PB 235, RRIM 600 e PR 107 apresentaram melhor desempenho, com um perímetro do caule 8,12% maior que o dos clones RRIM 701 e GT 1, notadamente os de menor vigor. A interação enxerto vs. porta-enxerto não foi significativa

Movement syndromes of a Neotropical frugivorous bat inhabiting heterogeneous landscapes in Brazil

Background There is growing evidence that individuals within populations can vary in both habitat use and movement behavior, but it is still not clear how these two relate to each other. The aim of this study was to test if and how individual bats in a Stunira lilium population differ in their movement activity and preferences for landscape features in a correlated manner. Methods We collected data on movements of 27 individuals using radio telemetry. We fitted a heterogeneous-space diffusion model to the movement data in order to evaluate signals of movement variation among individuals. Results S. lilium individuals generally preferred open habitat with Solanum fruits, regularly switched between forest and open areas, and showed high site fidelity. Movement variation among individuals could be summarized in four movement syndromes: (1) average individuals, (2) forest specialists, (3) explorers which prefer Piper, and (4) open area specialists which prefer Solanum and Cecropia. Conclusions Individual preferences for landscape features plus food resource and movement activity were correlated, resulting in different movement syndromes. Individual variation in preferences for landscape elements and food resources highlight the importance of incorporating explicitly the interaction between landscape structure and individual heterogeneity in descriptions of animal movement.Peer reviewe

Assessment of awake bruxism in undergraduate students, using Ecological Momentary Assessment, through WhatsApp

This study assessed awake bruxism (AB) in undergraduate students using WhatsApp and examined the association of this behavior with quality of life and anxiety. The sample was composed of 36 healthy young adults of both genders, with an average age of 20.74 years. AB behaviors (teeth contact, teeth clenching, teeth grinding and mandible bracing) and relaxed jaw muscles were reported with Ecological Momentary Assessment, through WhatsApp, 15 times a day, for 7 days, between 8:00 am and 7:00 pm. Quality of Life (QoL) and anxiety were assessed using the SF-36 and GAD-7 questionnaires, respectively. The Mann-Whitney U non-parametric, Pearson and Spearman correlation and Pairwise non-parametric multiple comparisons 2- to-2 tests were used. The frequency of AB was 40.7%. The most frequent AB behavior was teeth contact (23.1%). Higher frequency of AB occurred on weekdays (42.3%) compared to the weekend (35.5%) (p&lt;0.05). There was a negative correlation of AB behaviors and mandible bracing with the QoL - emotional aspects domain (p&lt;0.05) and positive correlation of mandible bracing with anxiety (p&lt;0.01). There was no difference between genders for QoL, anxiety and AB behaviors (p&gt;0.05). This study highlights the importance of AB and anxiety control to improve undergraduate students’ quality of life.This study assessed awake bruxism (AB) in undergraduate students using WhatsApp and examined the association of this behavior with quality of life and anxiety.
