Role of Glycosidic Aroma Precursors on the odorant profiles of Grenache noir and Syrah Wines from the Rhone valley. Part 2: characterisation of derived compounds
Authors: Segurel Marie A. , Baumes Raymond L. , Langlois Dominique , Riou Christine , Razungles Alain
Published: June 2016

Aims: Grenache noir and Syrah are the predominant grape varieties in the French Rhone valley vineyard. This study aimed at identifying the odorants generated from glycoconjugates extracted from wines made with Grenache noir and Syrah.

Methods and results: Synthetic model wines enriched with glycoconjugates, treated or not with enzymes, were stored at 45 °C for 3 weeks, or at 13 °C for 18 months. Aromas generated were extracted and analyzed by GC-Olfactometry (only samples from accelerated aging) and were further quantitatively determined by GC-MS. Analysis of the extracts allowed to identify 49 odorants, including 27 that could be aglycons, or related compounds, of glycoconjugates from the grapes. In addition, the active compounds were quantified in similar experiments led in conditions of natural aging for 18 months.

Conclusion: The two varieties, Grenache noir and Syrah, were distinguishable by 14 odorant zones. Multivariate analyses (PCA) performed with the amounts of aroma compounds formed during both model and natural aging confirmed the effect of the glycosidase treatment on the acceleration of the aroma compounds formation and on the increase of the varietal differences of the wines.

Significance and impact of study: GC-Olfactometry coupled with GCMS were good techniques to indentify and apreciate the odorants generated from glycoconjugates in the wines of Syrah and Grenache Noir, but in the context of a blend of odors, these techniques showed their limits and did not permit to determine the real impact of a molecule in the global aroma of the wine perceived by the taster. Other methods as additive techniques should be used to complete this study.
Implementing Question and Answer Technique to Enhance Students’ Speaking Ability at SMP Islam Paramitha Malang
Authors: Adi Adi
Published: June 2016

Speaking is one of language skills which has to be mastered by the students. By being able to speak, students will be able to transfer their thought to others. Unfortunately, sometimes students, at SMP Islam Paramitha especially, failed to utter their idea in spoken manner due to several factors as lack of vocabulary, not knowing what and how to say the ideas, and mostly feeling unconfident. This problem  cannot be neglected; therefore, the researcher decided to carry out a two-cycle Classroom Action Research (CAR). In This CAR the researcher implemented question and answer technique to improve students’ speaking ability on expressing their daily activities. By using observation sheets, interview guide, and test, it was found that 70% of the students had been successfully improving their speaking ability. As a result, the intended spoken communication, either between students and students or teacher and students, did take place.
Highly Proficiency Learners on Noticing Strategy towards Corrective Feedback
Authors: Mufanti Restu
Published: June 2016

This study primarily aims at capturing the nature of how highly proficiency learners (HPLs) employ noticing strategies in processing the indirect corrective feedback. The results of this study can be adapted by others learners to apply the strategy used by HPLs in noticing corrective feedback so that they can improve their writing ability. To meet the goal, a study on the way highly proficiency learners notice indirect corrective feedback that focused on three language aspects, i.e., lexis, grammar, and content was conducted. Observation and in depth- interview were used as the instruments to collect the data. The subjects chosen were six students who have a good performance on their writing. This study revealed that the HPLs are able to employ various noticing strategies when they are processing the indirect corrective feedback. They seem more cognizant of the problems they encounter and more capable of taking an action to respond the feedback given. Some noticing strategies are identified to apply in processing the feedback that are suited on the nature of the problems, such as by making any comparison, connection, correlation, identification of error, recalling the past experience/ knowledge and self-inquiry. However, three aspects that often applied by HPLs are identification of error well, recalling the past knowledge and self-inquiry.
Simultaneous History-Matching Approach by Use of Reservoir-Characterization and Reservoir-Simulation Studies
Authors: Avansi Guilherme Daniel , Maschio Célio , Schiozer Denis José
Published: June 2016

Reservoir characterization is the key to success in history matching and production forecasting. Thus, numerical simulation becomes a powerful tool to achieve a reliable model by quantifying the effect of uncertainties in field development and management planning, calibrating a model with history data, and forecasting field production. History matching is integrated into several areas, such as geology (geological characterization and petrophysical attributes), geophysics (4D-seismic data), statistical approaches (Bayesian theory and Markov field), and computer science (evolutionary algorithms). Although most integrated-history-matching studies use a unique objective function (OF), this is not enough. History matching by simultaneous calibrations of different OFs is necessary because all OFs must be within the acceptance range as well as maintain the consistency of generated geological models during reservoir characterization. The main goal of this work is to integrate history matching and reservoir characterization, applying a simultaneous calibration of different OFs in a history-matching procedure, and keeping the geological consistency in an adjustment approach to reliably forecast production. We also integrate virtual wells and geostatistical methods into the reservoir characterization to ensure realistic geomodels, avoiding the geological discontinuities, to match the reservoir numerical model. The proposed methodology comprises a geostatistical method to model the spatial reservoir-property distribution on the basis of the well-log data; numerical simulation; and adjusting conditional realizations (models) on the basis of geological modeling (variogram model, vertical-proportion curve, and regularized well-log data). In addition, reservoir uncertainties are included, simultaneously adjusting different OFs to evaluate the history-matching process and virtual wells to perturb geological continuities. This methodology effectively preserves the consistency of geological models during the history-matching process. We also simultaneously combine different OFs to calibrate and validate the models with well-production data. Reliable numerical and geological models are used in forecasting production under uncertainties to validate the integrated procedure.

Historically, the primary objective of cotton (Gossypium hirsutum L.) breeding programs was to improve the quantity and quality of cotton fiber. Because of the added value of cottonseed and its many uses, including a feed and human food source, there is interest in developing cotton breeding programs that focus improvement efforts simultaneously on cotton fiber and seed. Genetic analysis of cottonseed traits, such as protein and oil, is a prerequisite to building new joint fiber and seed cotton breeding programs. In this study, we conducted a genetic analysis of a diverse set of elite upland cotton germplasm for cottonseed protein and oil. Environment was responsible for a sizeable portion of the total variation for protein and oil, and genetics accounted for a larger portion of variation for oil than protein. Genotype × environment (G × E) interactions significantly impacted oil but not protein. Genotypic correlation analysis found a strong, negative relationship between protein and oil. Positive genotypic correlations were found for protein and several agronomic traits including lint yield; whereas, negative correlations were found between oil and lint yield along with other agronomic traits. Overall, results showed very little association between protein, oil, and fiber quality traits. These findings indicate that altering protein and oil seed composition will impact yield and yield component traits. However, alterations in seed composition should not impact fiber quality.
Patterns of Heterosis in Three Distinct Inbred Populations of Spring Brassica napus Canola
Authors: Rahman Habibur , Bennett Rick A. , Yang Rong‐Cai
Published: June 2016

Allelic diversity of the allied species of Brassica napus L. as well as of the winter form of this species has been demonstrated to be related with increasing productivity of hybrid spring B. napus cultivars. To compare potential value of the different gene pools of Brassica species three spring B. napus inbred populations were developed by use of a B. oleracea L. line, a spring B. napus breeding line, and a winter B. napus cultivar crossed to a spring B. napus ‘Hi‐Q’; and test hybrids of these inbred lines were produced by crossing with Hi‐Q as the common tester. Mid‐parent heterosis (MPH) showed a negative correlation with seed yield of the inbred lines in all three populations; however, a positive correlation existed between seed yield of the inbred lines and heterosis over Hi‐Q (HiQH) (or, inbred vs. hybrid yield). On average, the level of MPH in hybrid of the inbred lines derived from B. napus × B. oleracea cross was twice greater than the level of heterosis found for the inbred lines derived from spring × spring or winter × spring B. napus crosses. The inbred population derived from winter × spring cross gave highest seed yield, and this population also gave highest HiQH. The results suggested that B. oleracea and winter canola could be used in spring B. napus canola breeding for accumulating additive and non‐additive effect genes for increased seed yield in hybrid cultivars.
Depresión en la mujer: ¿expresión de la realidad actual?
Authors: Ochoa Gómez Carolina , Cruz Agudelo Andrés Felipe , Moreno Carmona Norman Darío
Published: June 2016

De acuerdo a múltiples estudios realizados a nivel mundial, la depresión podría afectar alrededor de 350 millones de personas en el mundo. En Colombia, y particularmente en Medellín, el fenómeno también se ha manifestado de forma representativa, especialmente en la población femenina, que prácticamente duplica el número de casos de sus pares masculinos. El objetivo de este artículo es presentar una reseña de diferentes estudios realizados en mayor medida en países de habla hispana que validan como proposición inicial la posibilidad de que la población mundial y particularmente la mujer, desarrolle un síntoma que va en aumento, llamado depresión. La metodología utilizada fue el rastreo de fuentes bibliográficas producto de investigación, realizadas en los últimos diez años, especialmente en España y Latinoamérica. Los hallazgos muestran que la búsqueda de equidad de género, los nuevos roles laborales que se alternan con los quehaceres domésticos, los apegos y algunas circunstancias de orden familiar son factores determinantes frente al fenómeno de la depresión en la mujer. © Revista Colombiana de Ciencias Sociales.

Authors: Montoya Zuluaga Diana Marcela , Castaño Hincapié Nancy , Moreno Carmona Norman Darío
Published: June 2016

De acuerdo con los resultados de la encuesta de Profamilia (2010) y del Mapa Mundial de la Familia (Trends, 2013) los niños y jóvenes están creciendo con la ausencia física de alguno de los padres y algunos, a pesar de la presencia física de ellos, experimentan sentimientos de ausencia, pues al parecer han cambiado las formas de acompañamiento. Se hace necesario indagar por los recursos alternativos a la familia con los que están contando las nuevas generaciones, con el fin de ofrecer otras posibilidades desde lo social, institucional, personal, familiar, comunitario, que permita la construcción de bienestar en las personas. El objetivo del presente artículo de revisión es mostrar las diferentes investigaciones de los últimos diez años relacionadas con recursos psicosociales, bienestar subjetivo y sentimientos de ausencia. La metodología utilizada fue el rastreo de fuentes bibliográficas producto de investigación y de revisión teórica. Los resultadosrevelan que las personas cuentan con instituciones, grupos, comunidades y recursos internos que les permiten construir un proyecto de vida que genere bienestar. © Revista Colombiana de Ciencias Sociales.
Justificar, fundamentar y pensar: una reflexión sobre el uso de las bases fenomenológico-existenciales en el enfoque humanista en Psicología
Authors: Serra Undurraga Jacqueline Karen A.
Published: June 2016

Este artículo toma los aportes de autores que se han dedicado a pensar las bases del enfoque humanista en psicología como: Villegas, Quitmann, Gendlin, Moreira, Martínez, Kriz, Gondra, Capra, Sassenfeld y Moncada, para reflexionar en torno a los usos que se le han dado a las bases fenomenológico-existenciales en el enfoque humanista. Para esto, se analizan los postulados de importantes exponentes de este enfoque como: Maslow, Rogers, Gendlin y Perls. A partir de esta reflexión crítica se propone una diferenciación entre el justificar, el fundamentar y el pensar, como tres usos que se le dan a las bases fenomenológico-existenciales en el enfoque humanista en psicología. En el artículo se desarrolla que, a su vez, estos usos reflejan distintos modos de aproximarse al conocimiento: justificar se refiere al uso de las bases filosóficas para la validación académica, fundamentar tiene relación con el uso de las bases filosóficas para estructurar la teoría y pensar tiene que ver con utilizar la fundamentación de forma dialógica para seguir pensando. Se concluye que existe una filosofía implícita cartesiana, objetivista y atomista, al usar las bases fenomenológico-existenciales solo al nivel de la justificación; con esto se propone que algunos psicólogos humanistas a pesar de afirmar poseer bases filosóficas fenomenológicas existenciales, no aplican estas a sus postulados. Por último, se resalta la importancia de pensar dialógicamente la psicología para cuestionar la teoría y avanzar en el conocimiento. © Revista Colombiana de Ciencias Sociales.
Corrupción en la función pública: un estudio sobre correlaciones entre corrupción, calidad de la democracia, gobernanza, desigualdad de renta y desempleo en el mundo (2008-2012)
Authors: Perez Bernardes de Moraes Thiago , Da Silva Torrecillas Geraldo Leopoldo
Published: June 2016

El estudio cuantitativo de la corrupción ha crecido en las últimas décadas, abriendo caminos sin precedentes para la pesquisa social. En este trabajo, se hace una comparación transnacional sobre la percepción de corrupción en la función pública desde 2008 hasta 2012. Se trabaja con tres hipótesis: 1) la corrupción es más frecuente en países con menor calidad democrática; 2) todos los indicadores de gobernanza ejercen algún efecto sobre la corrupción; 3) la desigualdad es un importante predictor del nivel de corrupción, aún más que el desempleo. Para probar estas hipótesis se utilizan datos del Democracy Ranking of the Quality of Democracy, Corruption Perception Index, Worldwide Governance Indicators, datos del World Development Indicators y del Banco Mundial, datos estos que calculan el nivel global de desempleo y el índice Gini, que mide la desigualdad de consumo y renta. Los resultados muestran que las dos primeras hipótesis son adherentes, ya que hay alta correlación negativa entre corrupción en la función pública y cualidad de la democracia además de los seis indicadores de gobernanza. La tercera hipótesis muestra relativa adherencia pues, desigualdad de renta y desempleo están correlacionados con la corrupción en el funcionalismo público, sin embargo, la correlación tiene bajo valor de significancia, lo que indica que estos dos factores son apenas parte de un todo entre factores que componen el nivel de corrupción. © Revista Colombiana de Ciencias Sociales.
Periodismo y política: polémicas y confrontaciones en la coyuntura electoral 1941-1942. El diario Vanguardia Liberal y la defensa del partido liberal
Authors: Acevedo Tarazona Álvaro
Published: June 2016

El propósito de este artículo es estudiar las polémicas y las confrontaciones políticas presentadas en la coyuntura electoral de 1941 y 1942 a través de las páginas del periódico bumangués Vanguardia Liberal, donde el espectro de confrontaciones quedó expuesto en múltiples frentes que constituyeron la defensa del régimen liberal para los años siguientes. En el trabajo se resaltan las principales figuras del conservatismo y del liberalismo, de la misma manera que los periódicos que se enfrentaron en intercambios de mensajes para defender o denunciar actos que favorecían o perjudicaban los intereses electorales. Claramente, se puede determinar la principal función del periódico para la época como instrumento que orientó la intención del electorado manteniéndolo firme y leal a los idearios del liberalismo respecto a las campañas de difamación de los periódicos conservadores. © Revista Colombiana de Ciencias Sociales.

Prácticas que configuran lo político. Una hermenéutica arendtiana de los relatos familiares
Authors: González Bedoya Diana María
Published: June 2016

Este artículo pretende establecer una relación entre la perspectiva arendtiana de la comprensión y las prácticas cotidianas de la familia, para argumentar que es posible hacer una hermenéutica comprensiva de los relatos familiares para encontrar en ellos los sentidos políticos que han construido. Para Arendt, la comprensión es una tarea existencial permanente que implica un diálogo consigo mismo y con los otros y, ser capaces de reflexionar y construir un lugar distinto en el mundo. La política la constituye la construcción de un mundo común -entre nos- y la posibilidad de transformar juntos ese mundo, y lo político, para Arendt, es la participación del espacio entre nos, que implica reconocerse como parte de un mundo compartido. Desde la perspectiva arendtiana, la pluralidad y la acción política solo son posibles en el espacio público, lo cual excluye a la familia como espacio para la política; sin embargo, se plantea que es el primer espacio en el cual se expresa la pluralidad, se prefiguran las identidades y se configura el amor mundi. © Revista Colombiana de Ciencias Sociales.

Teniendo en cuenta el rol fundamental del apego parental en el desarrollo de diferentes recursos socio-emocionales, el objetivo de este trabajo fue estudiar si la percepción del apego parental, se relaciona específicamente con la conducta prosocial adolescente. Método: se trabajó con una muestra no probabilística intencional de 285 adolescentes (216 mujeres y 69 varones) de entre 14 y 18 años (M = 15,68; DE = 1,14), de Córdoba, Argentina. Previa autorización de los padres y consentimiento informado, se les administró la versión traducida y validada en Argentina del Cuestionario de Apego Parental de Kenny (1987) y la versión traducida y validada para adolescentes argentinos del Prosocial Tendencies Measure (PTM) de Carlo & Randall (2002). Se realizó un Análisis Multivariado de Variancia (MANOVA), cuyos resultados indicaron diferencias significativas en el perfil de prosocialidad en función del apego seguro/positivo (F de Hotelling (8.556) = 3.33; p = .001). Los resultados de los análisis univariados correspondientes a cada una de las dimensiones de la conducta prosocial evaluada, se discuten en función de los desarrollos teóricos y empíricos encontrados hasta el momento, encontrando una consistencia general entre los mismos. © Revista Colombiana de Ciencias Sociales.

Published: June 2016

Se propone el museo como espacio educativo y se discute su rol en la enseñanza disciplinar en la educación superior. Se presenta una experiencia educativa en torno al Museo de Historia de la Psicología de la Facultad de Psicología de la Universidad Nacional de San Luis (Argentina), y su aporte a la formación de competencias generales y específicas de los futuros psicólogos. Se asume con los estudiantes el rol político de una historia cultural disciplinar que cuestiona la configuración de modelos científicos profesionales. Se realiza una propuesta de investigación de objetos culturales que representan diversas tradiciones disciplinares. Desde la consigna de descubrir objetos históricos en contexto, investigarlos, ponerlos en valor y comunicar los resultados. Se interpela el pasado disciplinar: sus certezas, ortodoxias y hegemonías socialmente construidas, y se configura un espacio de formación de competencias científico-profesionales. Asimismo, se propone la participación en el Museo como espacio de comunicación pública de la ciencia, para la incidencia en la cultura más amplia del público no especializado.© Revista Colombiana de Ciencias Sociales.

A mediados del mes de septiembre de 2015, una imagen sacudía las conciencias del planeta entero y movilizó (bien que de manera lamentablemente efímera), la política europea. Se trataba del cadáver de un niño sirio ahogado en una playa de Grecia. No es lugar, ni ocasión para analizar la tragedia, sus consecuencias, ni mucho menos entrar en el fondo del asunto, pero sí puede servirnos como ejemplo de algo que, en ciencias sociales venimos reclamando como reto desde hace mucho tiempo: el uso de lo visual en nuestras investigaciones, la inmensa potencia de sus contenidos. Antes de la publicación de la imagen mencionada numerosos titulares daban un dato fidedigno: diez mil víctimas civiles en el conflicto sirio, la cuarta parte ellas niños. ¿Por qué las palabras “dos mil quinientos” o el número “2.500”, en ambos casos referidas a “niños muertos”, no movilizó a nadie y la imagen de uno solo de ellos sí? En ciencias sociales utilizamos profusamente datos numéricos (con metodología cuantitativa) y datos textuales (con metodología cualitativa) pero, ¿qué hay del uso de datos de tipo visual?© Revista Colombiana de Ciencias Sociales.

Uma das formas de estudar a precipitação pluviométrica é através de Índices de Anomalia de Chuva (IAC), que ajudam a monitorar anos de seca e chuva excessiva, permitindo averiguar os impactos que o clima global causa sobre a distribuição pluviométrica do local. Nesse contexto, o presente trabalho objetivou analisar IAC em quatro municípios de diferentes mesorregiões do Estado de Pernambuco, evidenciando os anos de seca e de chuva. Para realização desta pesquisa, foram selecionados os municípios: Barreiros, Caruaru, Floresta e Petrolina, das mesorregiões da Zona da Mata, Agreste, Sertão Pernambucano e Sertão do São Francisco, respectivamente. Os dados de precipitação das séries históricas de cada localidade foram obtidos na Agência Pernambucana de Águas e Clima. Com os dados, foram realizados os cálculos do IAC positivo e negativo, com base na normal climatológica e médias dos 10 anos de máximas e mínimas precipitações e, em sequência, houve a classificação de anos secos e úmidos de acordo com as classes de intensidade do IAC.  Dentre os municípios analisados, Barreiros foi o mais úmido, reflexo da precipitação média anual (2026,79 mm) com o IAC variando entre -5,76 e 6,03. Para Caruaru, ocorreram 33 anos com desvios negativos e 25 com desvios positivos e o IAC variou entre -3,99 e 4,06. Em Floresta, o IAC variou entre -4,82 e 7,69 e ocorreu 1 ano extremamente úmido e 2 extremamente secos. E, em Petrolina, ocorreram 5 anos extremamente úmidos e 1 extremamente seco, sendo que o IAC oscilou entre 5,31 e 7,24. Conclui-se que a utilização do IAC, positivos e negativos, para as cidades analisadas, garante um resultado mais preciso do índice, refletindo em um planejamento agrícola mais elaborado para essas cidades. Sendo que a elevada quantidade de anos que apresentaram IAC negativo, para esses municípios, somada a significativa oscilação entre os anos úmidos e secos das series históricas, caracterizam essas localidades como instáveis para a produção agrícola de sequeiro.

Alternating Periods of High and Low-Entropy Neural Ensemble Activity During Image Processing in the Primary Visual Cortex of Rats
Authors: Li Xiaoyuan , Li Qiwei , Shi Li , Jiao Liucheng
Published: June 2016

The response properties of individual neurons in the primary visual cortex (V1) are among the most thoroughly described in the mammaliancentral nervous system, but they reveal less about higher-order processes like visual perception. Neural activity is highly nonlinear and non-stationary over time, greatly complicating the relationships among the spatiotemporal characteristics of visual stimuli, local field potential (LFP) signal components, and the underlying neuronal activity patterns. We applied discrete wavelet transformation to detect new features of the LFP that may better describe the association between visual input and neural ensemble activity. The relative wavelet energy (RWE), wavelet entropy (WS), and the mean WS were computed from LFPs recorded in rat V1 during three distinct visual stimuli: low ambient light, a uniform grey computer screen, and simple pictures of common scenes. The time evolution of the RWE within the γ band (31-62.5 Hz) was the dominant component over certain periods during visual stimulation. Mean WS decreased with increasing complexity of the visual image, and the time-dependent WS alternated between periods of highly ordered and disordered population activity. In conclusion, these alternating periods of high and low WS may correspond to different aspects of visual processing, such as feature extraction and perception.
The Interactive Role of Difficulty and Incentives in Explaining the Annual Earnings Forecast Walkdown
Authors: Bradshaw Mark T. , Lee Lian Fen , Peterson Kyle
Published: June 2016

The within-year walkdown of analysts' earnings forecasts has largely been attributed to analysts' incentives to curry favor with managers. We appeal to cognitive psychology literature on motivated reasoning and propose that forecasting difficulty interacts with such incentives to yield the observed walkdown. Higher forecasting difficulty generates a wider range of outcomes from which analysts can justify optimistically biased forecasts. In regression analyses, we find that the interaction between analysts' incentives for optimism and difficulty exhibits the strongest effect on earnings walkdowns. We also examine revenue forecasts as a benchmark of lower forecasting difficulty and find that revenue walkdowns are relatively diminutive. However, when analysts forecast losses, revenue forecasts are more critical and exhibit markedly steeper walkdowns. Our results suggest that analyst forecast walkdowns are better characterized by an interactive effect between analysts' strategic incentives for optimism and forecasting difficulty.

OBJECTIVE

Obesity and type 2 diabetes mellitus (T2DM) are associated with altered food-related neuronal functions. Besides weight loss, substantial improvement of glucose metabolism in patients with T2DM can be achieved by bariatric surgery. We aimed to target the neuronal and behavioral correlates of improved glycemic control after bariatric surgery.

RESEARCH DESIGN AND METHODS

Two patient groups with T2DM were recruited. The treatment group (n = 12) consisted of patients who had undergone Roux-en-Y gastric bypass (RYGB) surgery, and a control group consisted of patients who did not undergo surgery (n = 12). The groups were matched for age and current BMI. HbA1c was matched by using the presurgical HbA1c of the RYGB group and the current HbA1c of the nonsurgical group. Neuronal activation during a food reward task was measured using functional MRI (fMRI). Behavioral data were assessed through questionnaires.

RESULTS

RYGB improved HbA1c from 7.07 ± 0.50 to 5.70 ± 0.16% (P < 0.05) and BMI from 52.21 ± 1.90 to 35.71 ± 0.84 kg/m2 (P < 0.001). Behavioral results showed lower wanting and liking scores as well as lower eating behavior–related pathologies for the patients after RYGB than for similar obese subjects without surgery but with impaired glycemic control. The fMRI analysis showed higher activation for the nonsurgical group in areas associated with inhibition and reward as well as in the precuneus, a major connectivity hub in the brain. By contrast, patients after RYGB showed higher activation in the visual, motor, cognitive control, memory, and gustatory regions.

CONCLUSIONS

In obese patients with diabetes, RYGB normalizes glycemic control and leads to food reward–related brain activation patterns that are different from those of obese patients with less-well-controlled T2DM and without bariatric surgery. The differences in food reward processing might be one factor in determining the outcome of bariatric surgery in patients with T2DM.
Compromised Epistemologies: The Ethics of Historiographic Metatheatre in Tom Stoppard’sTravestiesandArcadia
Authors: Zapkin Phillip
Published: June 2016

Tom Stoppard uses historiographic metatheatre to question the efficacy of historical narratives: plays such as Travesties directly address the constructed texture of history. However, partially because the 1809 scenes in Arcadia are naturalistic, critics generally accept Arcadia as presenting a “real” history. But taking anything in Stoppard’s plays at face value is a crucial mistake. Instead, we should read Arcadia as participating in a self-consciously destabilizing cultural project building a historiography of error – like Travesties, but through a less obviously constructed historiographic metatheatre – a reading that prompts us to reconsider standard narratives of Stoppard’s development as a playwright of epistemological uncertainty. Part of Stoppard’s joyous humour in Arcadia goes beyond satirizing Bernard and extends to the critical misreadings through which we, as critics, reproduce Bernard’s unreliable thesis and, like him, risk convincing ourselves that we are right. Taking Arcadia at face value undermines the ethical imperative to uncertainty and multiplicity inherent in historiographic metatheatre, an ethic that runs through both Travesties and Arcadia.
Identity-based Signatures from Lattices: Simpler, Faster, Shorter
Authors: Tian Miaomiao , Huang Liusheng
Published: June 2016

Identity-based signature is an important technique for light-weight authentication. Recently, many efforts have been made to construct identity-based signatures over lattice assumptions since they would remain secure in future quantum age. In this paper we present a new identity-based signature scheme from lattice problems. This scheme is more efficient than other lattice-based identity-based signature schemes in terms of both computation and communication complexities. We prove its security in the random oracle model under short integer solution assumption that is as hard as approximating several worst-case lattice problems. We also extend the scheme to an identity-based message recovery signature scheme that has better performance.

Purpose: The effect of the transplantation of choroid plexus epithelial cells (CPECs) on locomotor improvement and tissue repair including axonal extension in spinal cord lesions was examined in rats with spinal cord injury (SCI).

Methods: CPECs were cultured from the choroid plexus of green fluorescent protein (GFP)-transgenic rats, and transplanted directly into the contusion-injured spinal cord lesions of rats of the same strain. Locomotor behaviors were evaluated based on BBB scores every week after transplantation until 4 weeks after transplantation. Histological and immunohistochemical examinations were performed at 2 days, and every week until 5 weeks after transplantation.

Results: Locomotor behaviors evaluated by the BBB score were significantly improved in cell-transplanted rats. Numerous axons grew, with occasional interactions with CPECs, through the astrocyte-devoid areas. These axons exhibited structural characteristics of peripheral nerves. GAP-43-positive axons were found at the border of the lesion 2 days after transplantation. Cavity formation was more reduced in cell-transplanted than control spinal cords. CPECs were found within the spinal cord lesion, and sometimes in association with astrocytes at the border of the lesion until 2 weeks after transplantation.

Conclusion: The transplantation of CPECs enhanced locomotor improvement and tissue recovery, including axonal regeneration, in rats with SCI.

Heart valve abnormalities are the most frequent cardiac manifestations in patients with antiphospholipid syndrome (APS) with or without systemic lupus erythrematosus (SLE) though clinically significant valvulopathy occurs rarely. Here, we present a case of a 20-year-old young lady presenting with intermittent fever and polyarthralgia for 2 weeks, breathlessness for 1 week and bilateral leg swelling for 3 days. On examination, moderate anaemia, high blood pressure, generalized lymphadenopathy and evidence of mitral regurgitation was found. She had Hb% 8.5 gm/dl with high ESR. In Doppler echocardiography, there was MVP with mitral regurgitation (MR) grade III. Transeosophageal echocardiography revealed features of type A Libman- Sacks (LS) endocarditis along with MVP and MR. Unfortunately; she had strongly positive ANA, positive anti ds-DNA, positive direct coombs test & positive antiphospholipid antibody (aPL) IgG with low C3 level & proteinuria. On the basis of clinical presentation and laboratory reports, a diagnosis of SLE with secondary antiphospholipid syndrome (APS) with LS endocarditis with secondary MVP with coombs positive haemolytic anaemia was made. For treatment purpose, she was transferred to the department of Rheumatology. After 1 month during her follow-up visit, she was improved clinically & echocardiogracally.Bangladesh Heart Journal 2015; 30(1) : 33-36
Nano-Crystallization of High-Entropy Amorphous NbTiAlSiWxNy Films Prepared by Magnetron Sputtering
Authors: Sheng Wenjie , Yang Xiao , Wang Cong , Zhang Yong
Published: June 2016

High-entropy amorphous NbTiAlSiWxNy films (x = 0 or 1, i.e., NbTiAlSiNy and NbTiAlSiWNy) were prepared by magnetron sputtering method in the atmosphere of a mixture of N2 + Ar (N2 + Ar = 24 standard cubic centimeter per minute (sccm)), where N2 = 0, 4, and 8 sccm). All the as-deposited films present amorphous structures, which remain stable at 700 °C for over 24 h. After heat treatment at 1000 °C the films began to crystalize, and while the NbTiAlSiNy films (N2 = 4, 8 sccm) exhibit a face-centered cubic (FCC) structure, the NbTiAlSiW metallic films show a body-centered cubic (BCC) structure and then transit into a FCC structure composed of nanoscaled particles with increasing nitrogen flow rate. The hardness and modulus of the as-deposited NbTiAlSiNy films reach maximum values of 20.5 GPa and 206.8 GPa, respectively. For the as-deposited NbTiAlSiWNy films, both modulus and hardness increased to maximum values of 13.6 GPa and 154.4 GPa, respectively, and then decrease as the N2 flow rate is increased. Both films could be potential candidates for protective coatings at high temperature.
