Employee engagement in the interpersonal context

2016 Summer.Includes bibliographical references.To advance the theoretical understanding and research on engagement, I examined how engagement spreads within the interpersonal context. I developed and tested a theoretical framework built upon Kahn’s (1990) conceptualization of employee engagement, Byrne’s (2015) newly proposed mechanism of engagement contagion, and research on team dynamics. The study sample included students (N = 148) working in teams on a semester-long course project. Through the measurement of engagement levels and individual differences related to emotional and cognitive contagion, I assessed two potential mechanisms for the transmission of engagement. Results showed that emotional contagion (as assessed with emotional contagion susceptibility) is not a significant predictor of change in affective engagement scores between two time points. Further, although cognitive contagion (as assessed with perceptions of shared mental models) significantly predicted change in cognitive engagement scores, students reporting higher levels of this construct experienced small changes in cognitive engagement. Based on these findings, recommendations for future research are discussed

Image Capture via Multiple Optical Paths

The present disclosure describes systems and methods that can capture multiple images from multiple optical paths on a single image sensor. More particularly, the multiple optical paths can be directed to the single image sensor, and the image sensor can be partitioned into one or more separate regions to capture the multiple images. An assembly of optical path folding elements can be configured to select one or more images from the multiple optical paths, and allow the selected images to be imaged on a corresponding partitioned region of the single image sensor. The system can actuate the assembly of optical path folding elements to select one or more images to be captured and/or achieve optical image stabilization of the one or more captured images. Keywords associated with the present disclosure include: computing systems (e.g., smartphone, smartwatch, mobile phone, mobile computer, laptop, headset, wearabale); camera; augmented reality; virtual reality; image capture; optical path; folding element; optical image stabilization; image sensor

Tres vueltas al sol vistas desde mi escuela: relato de una experiencia de extensión en el aula

Presentamos la experiencia de acompañar durante tres años a los estudiantes de una escuela primaria, tutelando el proceso de construcción de conocimientos de los niños respecto de los movimientos relativos del sistema Tierra-Sol. Desde el proyecto de extensión universitaria, se propusieron formas-otras (Santos, 2011) de trabajo didáctico para el abordaje de los conocimientos científicos, priorizando la proposición de modelos explicativos sobre fenómenos cotidianos tales como el movimiento del sol en el cielo. Estos modelos son construidos por los estudiantes a partir de su propia experienciación en el patio de su escuela, que deviene aula ampliada. Los modelos son contrastados fenomenológicamente, ajustados, debatidos y ampliados. A partir de ellos, los niños son capaces de establecer previsiones para eventos futuros o hipotetizar respecto de fenómenos producidos en otras locaciones, transformando esta tarea en una muy similar a la que realizan los científicos actuales. Se estableció una relación dialógica con la docente responsable de los cursos que devino en la incursión plena del equipo extensionista en los espacios institucionales, así como la incorporación de la docente al equipo, que a partir de la experiencia ganada asume la responsabilidad de la asesoría a otros docentes en miras de replicar la experiencia en otras instituciones.Facultad de Ciencias Astronómicas y GeofísicasFacultad de Ingenierí

PERCEPÇÃO DO ERRO NO PREPARO E ADMINISTRAÇÃO DE MEDICAMENTOS INTRAVENOSOS NUMA CLINICA MEDICA E CIRÚRGICA DE UM HOSPITAL PUBLICO

A enfermagem é responsável pelas últimas etapas da medicação que é o preparo e administração do medicamento. Este processo é susceptível a erros que podem ocorrer em qualquer uma das fases, porém, por vezes estes erros são atribuídos à enfermagem por serem os profissionais que estão em contato direto com o paciente. Isto aumenta a responsabilidade destes profissionais no processo de identificar, prevenir e notificar os erros (GALIZA et al., 2014; FRANCO et al., 2014)

WACCM-D Whole Atmosphere Community Climate Model with D-region ion chemistry

Energetic particle precipitation (EPP) and ion chemistry affect the neutral composition of the polar middle atmosphere. For example, production of odd nitrogen and odd hydrogen during strong events can decrease ozone by tens of percent. However, the standard ion chemistry parameterization used in atmospheric models neglects the effects on some important species, such as nitric acid. We present WACCM-D, a variant of the Whole Atmosphere Community Climate Model, which includes a set of lower ionosphere (D-region) chemistry: 307 reactions of 20 positive ions and 21 negative ions. We consider realistic ionization scenarios and compare the WACCM-D results to those from the Sodankylä Ion and Neutral Chemistry (SIC), a state-of-the-art 1-D model of the D-region chemistry. We show that WACCM-D produces well the main characteristics of the D-region ionosphere, as well as the overall proportion of important ion groups, in agreement with SIC. Comparison of ion concentrations shows that the WACCM-D bias is typically within ±10% or less below 70 km. At 70–90 km, when strong altitude gradients in ionization rates and/or ion concentrations exist, the bias can be larger for some groups but is still within tens of percent. Based on the good agreement overall and the fact that part of the differences are caused by different model setups, WACCM-D provides a state-of-the-art global representation of D-region ion chemistry and is therefore expected to improve EPP modeling considerably. These improvements are demonstrated in a companion paper by Andersson et al

Tradicionalidade de uso das plantas medicinais da Farmacopeia Brasileira

No Brasil contemporâneo, a relevância dos vegetais para a saúde pública está refletida na existência da PNPMF e de regulamentações da ANVISA voltadas para drogas vegetais e fitoterápicos. Entre elas, as monografias de plantas medicinais da Farmacopeia Brasileira estabelecem os requisitos de qualidade, sendo fundamental na elaboração, produção e controle de qualidade das plantas medicinais. Tendo em vista que o objetivo destas políticas é garantir o uso seguro e racional das plantas medicinais e também valorização da sociobiodiversidade brasileira, este trabalho teve como objetivo analisar como a 6a Edição da Farmacopeia Brasileira reflete a diversidade não só biológica, mas também cultural do país através da tradicionalidade de uso das espécies vegetais nativas do Brasil que nela estão contempladas. Foi realizada uma triagem das espécies vegetais nativas brasileiras citadas nas monografias de plantas medicinais na 6ª Edição da Farmacopeia Brasileira, sendo encontradas apenas 25 espécies nativas das 106 citadas. A partir das bases de dados a Flora e Funga do Brasil do Jardim Botânico do Rio de Janeiro, World Flora Online, Plants of the World Online e Tropicos, a nomenclatura científica das espécies nativas citadas também foi verificada, encontrando 10 nomes com erros. Seguindo a seleção das espécies, foi feito um levantamento bibliográfico sobre a tradicionalidade de uso destas espécies no Brasil a partir de estudos etnobotânicos que citam algum uso tradicional para cada espécie publicados nos últimos 10 anos. Para isso foi realizado um banco de dados contendo: nomes científicos atualizados, nomes populares, usos, partes utilizadas, comunidade provedora da informação e sua classificação (conforme citados no artigo), estado da federação em que se encontra a comunidade e artigos em as espécies foram citadas. Considerando os resultados do trabalho e o fato do país possuir a maior biodiversidade mundial e uma grande riqueza de conhecimentos sobre o manejo e uso das plantas medicinais, fica claro que a Farmacopeia Brasileira apresenta lacunas relativas à representação da diversidade não só biológica, mas também cultural do país. Assim, é possível afirmar que uma maior atenção deve ser dada à área da Botânica e da Etnobotânica na constituição das políticas públicas de modo a preencher lacunas existentes e cumprir com seus objetivos. Destaca-se a importância de bancos de dados como do presente estudo como uma ferramenta para proteção do conhecimento tradicional e do patrimônio genético do país.In Brazil, the relevance of plants for public health is reflected in the existence of the PNPMF and ANVISA regulations aimed at plant drugs and herbal medicines. Among them, the monographs of medicinal plants of the Brazilian Pharmacopoeia establish the quality requirements, being fundamental in the elaboration, production and quality control of medicinal plants. The objective of these policies is to guarantee the safe and rational use of medicinal plants and also the appreciation of Brazilian sociobiodiversity. So, this work aims to analyze how the 6th Edition of the Brazilian Pharmacopoeia reflects not only the biological diversity,but also the cultural diversity of the country by the traditional use of plant species native that are included in it. A searching of native Brazilian plant species cited in the monographs of medicinal plants in the 6th Edition of the Brazilian Pharmacopoeia was carried out, and only 25 native species were found out of the 106 cited. From the Flora and Funga do Brasil databases of the Botanical Garden of Rio de Janeiro, World Flora Online, Plants of the World Online and Tropicos, the scientific nomenclature of the cited native species was also verified, finding 10 names with erros. Following the selection of species, a bibliographic survey was carried out on the traditional use of these species in Brazil based on ethnobotanical studies that cite some traditional use for each species published in the last 10 years. With this search, a database was created with the following information compiled by species: updated scientific names, popular names, uses, used parts, information provider community and classification (as mentioned in the article), state of federation in which the community is located and articles on the species were cited. Considering the results and the fact that Brazil has the greatest biodiversity in the world and a great wealth of knowledge about the management and use of medicinal plants, it is clear that the Brazilian Pharmacopoeia presents gaps related to the representation of diversity, not only biological, but also cultural from the country. Thus, a greater attention should be given to the area of Botany and Ethnobotany in the constitution of public policies in order to fill existing gaps and fulfill its objectives. The importance of databases such as the present study is highlighted as a tool for the protection of traditional knowledge and the country's genetic heritage.223 p

THE QUARTIC OSCILLATOR AS A BASIS FOR ENERGY LEVEL CALCULATIONS OF SOME ANHARMONIC OSCILLATORS

This paper may be called for at the end of Session G if time permits.Author Institution: Department of Chemistry, University of California; Department of Chemistry, University of CaliforniaThe first twenty energy levels and wave functions for an oscillator with potential energy $V = ax^{4}$ have been obtained by diagonalizing a $100 \times 100$ Hamiltonian matrix in the representation of the harmonic oscillator. These wave functions have been used to calculate the matrix elements of $x, x^{2}, x^{3}, x^{4}$, and $x^{5}$ in the representation of the quartic oscillator. Application of these results to the calculations of energy levels and matrix elements for mixed harmonic-quartic oscillators and double-minimum potential wells will be discussed

Efecto del tratamiento térmico sobre la solubilidad proteica, el índice de ureasa y la composición química del haba (vicia faba l.) INIA 423 blanca gigante yunguyo

TesisEl trabajo tuvo como objetivo evaluar el efecto de la temperatura y el tiempo de tostado sobre la solubilidad proteica, el índice de ureasa y la composición química del haba (Vicia faba L.) de la variedad INIA 423 Blanca Gigante Yunguyo, a fin de determinar los parámetros óptimos de tratamiento térmico para obtener un producto de calidad. Las temperaturas de tostado fueron de 120 y 130°C, durante 10, 15 y 20 minutos por cada temperatura, para lo cual el haba fue tostada íntegra, luego descascarada, molida, tamizada y analizada. La solubilidad proteica se determinó por disolución en KOH al 0.2%; el índice de ureasa residual, a través de la prueba de la ureasa basada en la diferencia de pH y la composición química, por los métodos oficiales de la AOAC. Como control se utilizó el haba cruda. Los mejores tratamientos fueron a 120°C por 20 minutos y 130°C por 15 minutos, el tostado disminuyó (P<0.05) la solubilidad proteica (de 94% a 80.2% y 79%) y la actividad ureásica (de 0.21 a 0.01 y 0.01); asimismo, disminuyó (P<0.05) la composición química en humedad (de 7.7% a 4% y 4.2%), grasa (de 1.8% a 1.6% y 1.7%) y fibra (de 1.3% a 1.2% y 1.3%), y aumentó (P<0.05) en proteína (de 31.5% a 33% y 32.9%), ceniza (de 2.5% a 2.6% y 2.5%) y carbohidratos (de 55.2% a 57.6% y 57.5%). Los resultados indican que el tostado reduce la solubilidad proteica y el índice de ureasa residual a niveles óptimos y altera la composición química del haba, por lo que este proceso puede ser de utilidad para lograr el balance entre la degradación de los factores anti nutricionales (FANs) y el mantenimiento de la disponibilidad de aminoácido
