Triggering language and maths anxiety in non-medical prescribing students
Authors: Smith Charlotte , Penazzi Davide
Published: May 2020

Maths anxiety is a debilitating fear of mathematics, which often stems from early learning experiences. Despite their ability to confidently perform complex numerical tasks, such as drug calculations, as an intrinsic part of their role, health professionals often disclose experiencing maths anxiety. Health professionals who have returned to education to study non-medical prescribing are required to undertake a numeracy exam, which can trigger symptoms of maths anxiety. This study explores the use of language in teaching and learning numeracy with non-medical prescribing students, and identifies that use of terminology more closely aligned with health professionals' language results in lower levels of anxiety than using school-like mathematical terminology. The findings of this study can be used to inform supportive teaching practices for health professional educational courses that have a numeracy component.

Highlights

Organic cropping systems were less efficient in energy use.

Sugarcane for seed was the highest energy input due to the consumption of 12 t ha-1 of seed.

The second largest part of the energy input was the fuel consumed during mechanized operations.

Abstract.Analysis of energy use efficiency provides an assessment of non-renewable energy consumption; it is a useful indicator of environmental and long-term sustainability when comparing cropping systems. This study aimed to estimate the energy use efficiency of organic and conventional cropping systems of sugarcane for sugar production in central Cuba. Estimation of the energy use efficiency included analysis of four cropping systems. The energy input in the field until harvest and transport to the sugar mill was the limit of this analysis. The results showed that organic cropping systems were less efficient in energy use because of the greater number of field operations, mainly for weed control by manual and mechanical cultivation. Organic cropping systems also had lower yield compared with conventional systems due to their use of low doses of organic products, instead of agrochemical fertilizers, for plant nutrition. In all cropping systems evaluated, sugarcane used for seed was the largest part of the energy input due to the consumption of 12 t ha-1 of seed, representing an average of 89% of the total energy input for the sugarcane cropping systems. The second largest part of the energy input was the fuel consumed during mechanized operations. Irrigation was the third largest part of the energy input for organic cropping systems and the second largest part of the energy input for conventional cropping systems. Keywords: Agricultural systems, Energy balance, Energy input, Energy output.

Highlights

This review study identified five different ways of setting up a SWAT model for field-scale analysis.

Model setup for each field-scale modeling method and examples of application are discussed.

Benefits and limitations of each method are discussed.

Abstract. Although the Soil and Water Assessment Tool (SWAT) has been widely used as a watershed/basin scale model, recently there has been considerable interest in applying it at the field scale, especially for evaluation of best management practices and for building stakeholder confidence. In this study, a thorough review of the literature on field-scale application of SWAT was conducted. It was determined that there is more than one way of setting up a field-scale SWAT model depending on the spatial scale of the research as well as the research question to be answered. This article provides a detailed review of the methods used for field-scale SWAT modeling along with a summary of applications. This article also discusses the limitations and advantages of each method along with future research needs. The overarching goal of this article is to provide a valuable and time-conserving resource for future researchers interested in field-scale SWAT modeling.

Optimal harvest date is important to improve the yield and quality of peanut.

Peanut mesocarp color is one of the most popular methods for determining the optimal harvest date.

This article presents a smartphone-based system for determining optimal harvest date based on peanut mesocarp color.

Abstract. Harvesting at the right time is crucial to ensuring the best quality peanuts and maximizing yield. This article presents an offline system to assist farmers in evaluating peanut maturity. The system uses an automated method to determine peanut pod maturity, and it is portable, so it can be used in the field. Peanut maturity evaluation in the proposed system is based on the color of the mesocarp, which is the middle layer of the peanut shell. The mesocarp changes color over time from white to yellow, then dark brown, and finally black as the peanut reaches maturity. In the developed system, peanut pods are placed on a specially designed peanut sorting board, and the mesocarp color of each peanut pod is quantified by measuring the red, green, and blue (RGB) values with a smartphone camera. A nearest-neighbor classification algorithm is then used to sort each peanut into one of 25 colors on a color bar, which represents the different peanut maturity levels. To estimate the overall crop maturity, the ratio of the number of peanuts in the combined brown-black class to the total sample size must be determined. Using the developed system, this ratio was identified with 88.99% accuracy. In addition, the experimental results show that the inter-rater reliability of the developed system is comparable with manual methods involving human graders. Therefore, the system presented in this article shows great promise as a tool for helping to evaluate the maturity of peanut crops. Keywords: Mesocarp color, Peanut maturity grading, Peanut sorting board, Smartphone application.
Understanding Complex Flow Pathways within Lab-Scale Denitrifying Bioreactors with a Conservative Tracer
Authors: Pluer William T. , Walter M. Todd , Steinschneider Scott
Published: May 2020

Highlights

Storm size and media age did not significantly impact removal rate based on simulated storm events in lab bioreactors.

Post-hoc cluster analysis of bromide tracer time series identified distributed and preferential flow patterns.

Distributed flow cluster had significantly higher removal rate and removal efficiency than preferential cluster.

Abstract. Denitrifying bioreactors are designed to reduce excess nitrate (NO3-) pollution from agricultural fields. During storm-induced flow events, flow rate and hydraulic retention time (HRT) can fluctuate widely, which may disturb denitrification within bioreactors in ways not captured by current steady-flow models of NO3- removal rate (RR). This study investigated RR and removal efficiency (RE) during storm flows of variable size and duration to close the gap between existing steady-flow models and real-world flow event conditions. Three simulated storm flow events were run through six lab bioreactors, and RR and RE were calculated during and following each event. Our results show that bioreactors were able to attenuate flow such that event size and duration were not significant explanatory variables of RR. A k-means cluster analysis on characteristics of the outflow bromide tracer time series for each bioreactor during each event identified two major flow patterns. The cluster exhibiting a more distributed bromide load through time had a significantly higher average RR than the cluster with a bromide load time series more characteristic of preferential flow (24.8 and 22.0 g N m-3 d-1, respectively, p = 0.01). Bioreactors did not consistently display a given flow pattern but often changed between events. This suggests that flow patterns within lab bioreactors for each event are a more significant driver of RR than the external factor of the inflow hydrograph.

Efeito da Desordem em Excitações Magnéticas Elementares
Authors: Nascimento Elton M. , De Jesus Antonio Delson C.
Published: May 2020

A inclusão da desordem nos diversos sistemas físicos tem trazido relevantes resultados nos últimos anos no estudo das propriedades dos materiais. Devido à forte relação entre o modelo de Anderson e o de Heisenberg, para as excitações magnéticas elementares, é esperado que a desordem excerça um papel semelhante para ambos os casos, desta forma, munidos de recursos computacionais mais avançados, refizemos os cálculos para investigar o papel da desordem nos auto-estados de 1-magnon. Os resultados já encontrados para o caso eletrônico nos motivaram a investigar, também, a inclusão de correlações na distribuição de desordem para o caso magnético. Nossos resultados confirmaram as expectativas, ou seja, a inclusão de desordem nas constantes de interação de troca entre os pares de spin faz com que os seus auto-estados se limitem à uma região finita da cadeia. Já com a inclusão da correlação de longo alcance, esta tendência sofre uma mudança para um grau da correlação alpha > 1.0. Neste caso, surge uma banda de auto-estado estendido em epsilon < 2.5.

Published: May 2020

Na atualidade, o estudo da energia eletromagnética aplicada à medicina e biologia é um dos tópicos de pesquisas mais atraentes e de interesse crescente na comunidade científica internacional, e particularmente no Brasil. Vários esforços têm sido realizados para criar técnicas diagnósticas apoiadas na obtenção de imagens magnéticas e elétricas para ajudar de forma coadjuvante, e/ou substituir em alguns casos, as metodologias médicas de diagnóstico por imagens tradicionais. Neste trabalho mostramos o estado da arte, do ponto de vista experimental, destacando as mudanças nas dimensões dos sensores e no sistema de condicionamento analógico dos sinais medidos, para o registro de sinais de origem biológica. A imagem magnética medida sempre será degradada e ruidosa, devido tanto ao princípio físico (Lei Biot-Savart) envolvido na formação da imagem quanto ao próprio processo de medição da imagem. Os fundamentos básicos da formação das imagens magnéticas, bem como a solução do problema magnético direto e inverso, são mostrados. Apresentamos uma discussão do ponto de vista físico-matemático sobre o problema magnético inverso mal-condicionado e como ele influi na reconstrução das imagens das fontes magnéticas no interior de um objeto qualquer. Por fim, mencionamos de forma breve o método de filtragem espacial de Fourier como uma das possíveis técnicas na solução do problema magnético inverso.
Álgebra de Lie das Matrizes Gama da Equação de Dirac e dos Geradores do Grupo de Lorentz Homogêneo
Authors: Santiago Pereira Ricardo Martinho Lima
Published: May 2020

Este artigo aborda a construção de uma álgebra de Lie a partir do estudo da equação quântico relativística de Dirac tomando a condição de invariância relativística frente ao grupo de Lorentz Homogêneo no espaço de Minkowiski. Com base no estudo da teoria dos grupos contínuos, demonstramos que o estabelecimento de uma álgebra de Lie é uma condição suficiente para determinar as representações irredutíveis de um grupo contínuo. A partir da exigência de covariância da equação de Dirac frente ao grupo de Lorentz Homogêneo podemos estabelecer uma álgebra para as matrizes gama induzida pela álgebra dos geradores do grupo de Lorentz Homogêneo.

Modeling Cusp weak collision Kernel for the photon return of sodium beacon
Authors: Huang Jian , Yao Lianqun , Wang Gongchang
Published: May 2020

Sodium beacon adaptive optics (AO) system has been proved to be a highly productive tool for improving the resolving power of large-aperture ground-based telescope imaging. The performance of the AO system is mainly limited by photon return of the sodium beacon, which is determined by the coupling efficiency that characterizes the interaction rate between sodium laser and sodium atoms. The interaction processing is strictly influenced by the collisions of sodium atoms with other molecules (N2, O2). Most of the existing collision kernels are assumed as the “memoryless” hard collision, which is completely velocity reset in a Maxwellian distribution of the sodium atoms after scattering. To be more realistic, we adopt a more practical “memory” Cusp weak collision kernel, considering the velocity distribution of sodium atoms after collisions are correlated with the velocity before collision. By solving the Bloch equations, the processing for the interaction between sodium laser and sodium atom with Cusp kernel is established, and the coupling efficiency of sodium beacon with different collision kernel by analyzing the population is obtained. The researching results show that, for “memoryless” kernel, comparing to Cusp kernel with shaping parameter (s) of 100, the coupling efficiency is larger than 56% at best case; for sodium laser with 12% power detuned to D2b line and at a power density ranges from 10 to 100 W/m2, the coupling efficiency of “memoryless” kernel is nearly the same as “memory” Cusp kernel with s of 10, 100 and 3 Cusp kernel.
Adaptive thermal stabilization of an integrated photonic spectrometer using parasitic interference fringes
Authors: Teng Chu C. , Xiong Chi , Zhang Eric J. , Green William M. J. , Wysocki Gerard
Published: May 2020

Parasitic fringe drift from unwanted scatterings limits the long-term stability of waveguide-based optical spectrometers. Yet their spectral features provide relevant information that can be used to improve performance of the spectrometer. We show that fringe drift can be extracted and utilized to perform accurate thermal stabilization, especially in the case of integrated waveguide sensors. In this Letter, effective stabilization of a methane silicon photonic sensor is demonstrated, and significant reduction in fringe noise is clearly observed.

Published: May 2020

Conventional metal–semiconductor–metal (MSM) ultraviolet (UV) detectors have the disadvantage of limited adjustable structural parameters, finite electrical field, and long carrier path. In this Letter, we demonstrate a three-dimensional (3D) MSM structural AlN-based deep-UV (DUV) detector, fabricated through simple trench etching and metal deposition, while flip bonding to the silicon substrate forms a flip-chip 3D-MSM (FC-3DMSM) device. 3D-MSM devices exhibit improved responsiveness and response speed, compared with conventional MSM devices. Time-dependent photoresponse of all devices is also investigated here. The enhanced performance of the 3D-MSM device is to be attributed to the intensified electrical field from the 3D metal electrode configuration and the inhibition of the carrier vertical transport, which unambiguously increases the carrier collection efficiency and migration speed, and thus the responsivity and speed as well. This work should advance the design and fabrication of AlN-based DUV detectors.

Darcy Ribeiro, destacado antropólogo, educador e político brasileiro, é reconhecido por sua preocupação com a questão indígena e pela sua luta em defesa de uma educação pública e democrática. Nos seus escritos podemos encontrar subsídios sobre a realidade latino-americana e sobre a participação dos índios, negros e mestiços no processo de formação e desenvolvimento sociocultural do povo brasileiro, nos quais menciona, com muita propriedade, as causas históricas que estão na gênese dos níveis de desenvolvimento e desigualdade no Brasil. Nosso foco, neste texto, é explicitar o diagnóstico e a crítica de Darcy Ribeiro em relação à educação e à escola pública brasileira, tomando como referência principal o seu livro Nossa escola é uma calamidade, escrito em 1984, no qual analisa a situação da educação e da escola pública brasileira no final do século 20. A partir das provocações do autor, buscamos considerar os avanços e recuos da atual educação brasileira em relação às problemáticas apresentadas no final do século 20.

Sabe-se que Nietzsche, a genealogia, a história, texto publicado em 1971, consiste na materialização de um deslocamento indelével do procedimento investigativo foucaultiano, o qual suscitou, em contrapartida, uma série de controvérsias com os historiadores de então, sem ter arrefecido nas últimas décadas. Na esteira de tal horizonte, o presente estudo propõe-se a perspectivar as repercussões do legado foucaultiano e, em particular, os usos da noção de genealogia na produção bibliográfica em História da Educação veiculada, entre 1997 e 2017, nos três periódicos brasileiros voltados especificamente ao campo histórico-educacional. Para tanto, operou-se uma análise atenta ao conjunto e às especificidades de 42 artigos selecionados, de modo a dar a ver movimentos simultâneos, não obstante descentrados. As conclusões voltam-se às circunstâncias e condições que permitiriam determinado tipo de exercício investigativo de matriz historial ser designado foucaultiano.
Política afectiva en Las sillas de Álvaro Hernández
Authors: Hunter Lynette
Published: May 2020

La Política Afectiva se ocupa de las formas en que una persona genera devenir, conocer y valorar en un contexto situado donde los materiales son fundamentalmente no-conocidos, donde la complejidad somática del sí mismo está abierta al cambio, y cómo ese cambio se presencia en grupos colaborativos sociosituados. Este breve ensayo piensa a través de la manera en que las artes performativas están fundadas en prácticas sociosituadas donde se entrena lo afectivo, y que conducen al cambio social. Los performers no solo adquieren prácticas con materiales particulares no conocidos que fomentan los procesos afectivos para un sí-mismo procesual (selving)1 a través de formas tradicionales, sino que también aprenden prácticas que conducen a una política del escuchar más bien que a una del decir. La performatividad de esta política colaborativa ofrece soporte y sostenibilidad para lo que sucede con un grupo de personas cuando se produce un cambio. El ensayo recurrirá a un performance teatral concebido para una audiencia reducida [Sillas]: Qué no sabemos sobre una silla vacía, producida por el dramaturgo Álvaro Hernández, para integrar este breve estudio de la política afectiva con un ejemplo de la práctica teatral.
El Bondage con Cuerdas y las Corporalizaciones Afectivas: Un Análisis Rizomático
Authors: Carmina Ordean Iris , Pennington Heath
Published: May 2020

El bondage con cuerda, también conocido como shibari o kinbaku, es una práctica incorporada comúnmente asociada con BDSM (acrónimo de Bondage and Discipline, Dominance and Submission, Sadism and Masochism, en español, Bondage y Disciplina, Dominación y Sumisión, Sadismo y Masoquismo) en entornos académicos y no académicos. Sin embargo, el BDSM y discursos orientados al sexo no son inherentes a la práctica. Más bien, son solo dos formas potenciales de enmarcar el bondage con cuerdas, cuya pertinencia depende de cómo los practicantes eligen imaginarse a sí mismos y sus prácticas. Sin embargo, como la teoría feminista y queer ha argumentado, la identidad como una construcción social fija a menudo sirve objetivos normativos y regulatorios (Butler, 1990, 1993; Sedgwick, 1990). Basándose en el trabajo de campo de los autores, este artículo argumenta que el bondage con cuerdas funciona a través de relaciones afectivas, las cuales permiten a los practicantes pensarse a sí mismos fuera de estructuras identitarias de conexión, si así lo desean. En lugar de implicarse con problemáticas de las políticas de la identidad, los miembros pueden compartir sensaciones afectivas sentidas a través de la experiencia incorporada, dirigidas tanto hacia la cuerda como hacia otros cuerpos. Además, las percepciones afectivas del tiempo de los practicantes se ven alteradas 67Rope Bondage and Affective Embodiments: A rhizomatic analysis // Iris-Carmina Ordean // Heath PenningtonCHANGEpor sus experiencias corporales de bondage con cuerda que a menudo producen un estado de flujo (Ambler et al., 2017; Csikszentmihalyi, 1991; Newmahr, 2011). La práctica afectiva del bondage con cuerdas y las corporeidades autorreflexivas múltiples de los practicantes mientras interactúan con y a través de la cuerda incitan a los autores hacia un modelo rizomático de análisis (Deleuze y Guattari, 1987; Massumi, 1987). Tal modelo funciona en contra de las jerarquías de tiempo e identidad, que se desglosan a través de intercambios afectivos. Una comprensión rizomática de los patrones de crecimiento del bondage con cuerdas también puede informar estudios futuros sobre cambios no canónicos que ocurren en la práctica sin necesitar que esos cambios estén relacionados con los orígenes ostensibles del bondage de cuerdas en el Japón feudal, orígenes construidos cronológicamente para validar la existencia de la práctica.

La Pauta de Improvisación como Práctica: el Pautar como Método
Authors: O’Connor Kevin
Published: May 2020

El presente artículo documenta la pauta de improvisación – scoring - en tanto método que permite interactuar con la entidad biológico-material emergente denominada como fascia. Dicha interacción se generó en el contexto de un estudio de danza en tanto práctica-como-investigación (PI). La fascia – tejido conectivo – es una sustancia pegajosa que se conecta, divide y desliza entre los músculos, los órganos, la piel y las células del cuerpo humano. Se ha encontrado que este tejido es activo, inteligente y comunicativo. Es en últimas un órgano sensorial, que se subdivide y a la vez mantiene su unidad; puede llegar a parecer líquido, sólido y mucoso. La investigación de la fascia se realiza en centros de investigación por todo el mundo, e incluye a comunidades de biólogos, trabajadores somáticos, investigadores del cáncer, médicos, anatomistas y patólogos, bailarines, artistas del espectáculo y médicos de medicina china. En el contexto de la Práctica-como-Investigación, coreógrafos y artistas del performance aprenden con sus cuerpos a través de la exploración iterativa. El scoring es un método que toma ideas, imágenes y metáforas en relación a la fascia, y en vez de preguntarse por su significado, proporciona una serie de ejercicios que examinan el problema o la cuestión que llega a suscitar, de manera que colaborativamente se trabaja a través del movimiento. El pautar improvisadamente el movimiento de la fascia posibilita la generación de ciertas discusiones y prácticas compartidas de movimiento, las cuales producen frecuentemente nuevas formas de pensar los procesos corporales. Esta investigación forma parte de una discusión más amplia sobre la interrelación entre arte, ciencia y el performance de práctica-como-investigación. En esta se examinan las conexiones, los diálogos y las disonancias entre la investigación acerca de biologías emergentes y el performance. La pauta de improvisación como método se relaciona con el cuerpo en tanto material en proceso, inacabado y abierto. En últimas, este ensayo realiza la siguiente pregunta: en el contexto de un ensayo de performance, ¿cómo puede la pauta en tanto método, generar modos alternativos de en-actuar las comprensiones biológicas del cuerpo?
Tensión en la superficie: Improvisando el Performance de la Materialidad Tecnológica en la Obra Glitchbody/Nanostalgia [1454-2015]
Authors: Johnson Colin
Published: May 2020

En la primavera de 2015, UC (Universidad de California) Davis invitó al artista del performance Guillermo Gomez-Peña a colaborar en una pieza llamada Glitchbody / Nanostalgia [1454-2015]. Glitch intentó involucrar tecnologías de vigilancia social como Google Glass con las carnes, movimientos e imaginarios de cuerpos humanos. La performance final fue precedida por una semana de juegos y talleres intensivos, un ensayo realizado en colaboración con muchos de la comunidad de UC Davis. Este documento comienza repitiendo el marco que Glitchbody promulgó: uno que separaba el juego afectivo e improvisatorio del espacio de ensayo de un más representacional y en ocasiones fetichista, despliegue de tecnología en el performance. Al segregar los procesos para desarrollar el trabajo en el ensayo de las tecnologías digitales y conexiones en red que formaron tanto la ocasión para, como la atmosfera del performance, éste enmarcó la tecnología en un modo “prostético”, descuidando el potencial incorporado y las consecuencias materiales de los medios digitales. En este escrito, yo argumento que las nuevas tecnologías mediáticas, además de ser parte del medio (milieu) socio-situado para el performance, deben ser vistas como cuerpos con los cuales contender e improvisar.

Performance jams’ son las metodologías pedagógicas desarrolladas por Gómez-Peña (2011) en conjunción con el colectivo transdisciplinario de arte “La Pocha Nostra”. El jam es utilizado para germinar nuevas ideas, imágenes y personas para la noche del performance final. En estos espacios de improvisación, cuerpos entrenados de formas distintas se tocan y se mueven entre sí de maneras innovadoras.

Kawasan Jalan Pandanaran, merupakan kawasan jalan yang banyak dilalui oleh pengguna jalan, termasuk pejalan kaki. Sejak awal tahun 2013 penyediaan fasilitas jalur sirkulasi yang dibangun oleh Pemerintah Kota Semarang di kawasan ini berupa jalur pedestrian, kurang memberikan kenyamanan bagi penggunanya yang disebabkan jalur pedestrian yang digunakan aktivitas pedagang kaki lima yang sedang melakukan aktivitas perdagangan dan juga parkir mobil ataupun motor sembarangan pada jalurpedestrian di sepanjang Jalan Pandanaran. Hal ini yang menyebabkan ketidaknyamanan pada jalur pedestrian di jalan pandanaran karena jalur pedestrian mempunyai fungsi ganda. Tujuan penelitian ini adalah untuk mengukur tingkat kenyamanan jalur pedestrian di Jalan Pandanaran melalui persepsi masyarakat, dengan sasaran yaitu : 1) identifikasi kondisi eksisting dan fasilitas jalur pedestrian di Jalan Pandanaran yang berkaitan dengan aspek kenyamanan pengguna; 2) identifikasi karakteristik penggunajalur pejalan kaki di Jalan Pandanaran; 3) analisis kondisi eksisting kaitannya dengan fasilitas penunjang jalur pedestrian di Jalan Pandanaran kaitannya dengan aspek kenyamanan penggunanya; 4) tingkat kenyamanan jalur pedestrian di Jalan Pandanaran melalui persepsi masyarakat sebagai pejalan kaki. Metodologi dalam penelitian ini yaitu metode deskriptif kuantitatif dan metode purposive sampling yang di pilih dalam kriteria tertentu, dengan metode analisis deskriptif kuantitatif juga analisis standar jalurpedestrian. Hasil dari penelitian ini yaitu kenyamanan Jalur Pedestrian di Jalan Pandanaran dimana pada dimensi jalur pedestriam di Jalan Pandanaran sudah memenuhi standar minimum tentang pejalan kaki sebagai sebuah jalur pedestrian di perkotaan dan persepsi para pejalan kaki mengenai tingkat kenyamanan terdapat 2 aspek dari keseluruhan aspek kenyamanan seperti kebisingan kendaraan dan juga aroma tidak sedap, yang tidak memenuhi kriteria tingkat kenyamanan dengan capaian nilai persentase dari responden yaitu 52% > Persen > 36%. Dengan demikian perlu adanya pengelolaan lebih lanjut dan juga penegasan aturan mengenai sirkulasi dan pemanfaat jalur pedestrian serta mengevaluasi penataan PKL dan menambah petugas kebersihan yang dapat tetap menjaga kebersihan dan keindahan jalur pedestrian
