Associations Between Interoceptive Cognition and Age in Autism Spectrum Disorder and Typical Development
Authors: Mash Lisa E. , Schauder Kimberly B. , Cochran Channing , Park Sohee , Cascio Carissa J.
Published: February 2017

Interoceptive awareness is linked to emotional and social cognition, which are impaired in individuals with autism spectrum disorder (ASD). It is unknown how this ability is associated with age in either typical or atypical development. We used a standard test of interoceptive accuracy (IA) to investigate these questions in children and adults with and without ASD. Perceived number of heartbeats over 4 time intervals was compared with actual heart rate to determine IA. Effects of group, age, IQ, heart rate, and mental counting ability on accuracy were assessed using multiple regression. Post hoc correlations were performed to clarify significant interactions. Age was unrelated to IA in both groups when IQ ≥115. When IQ <115, this relationship was positive in typical development and negative in ASD. These results suggest that cognitive ability moderates the effect of age on IA differently in autism and typical development.
Visual Attention Processes and Oculomotor Control in Autism Spectrum Disorder: A Brief Review and Future Directions
Authors: Bellocchi Stéphanie , Henry Vincent , Baghdadli Amaria
Published: February 2017

Autism spectrum disorder (ASD) is defined as persistent deficits in social communication and social interaction, and restricted, repetitive patterns of behavior, interests or activities Diagnostic and Statistical Manual of Mental Disorders (5th ed., DSM-5; American Psychiatric Association, 2013). However, individuals with ASD show clearly atypical visual patterns. So far, indications of abnormal visual attention and oculomotor control concerning stimuli independent of social function in ASD have been found. The same findings have been shown in individuals suffering of other neurodevelopmental disorders (e.g., developmental coordination disorder and developmental dyslexia [DD]). Furthermore, visual attention processes and oculomotor control are supposed to be subserved by the magnocellular visual system, which has been found, in turn, to be dysfunctional in ASD and other neurodevelopmental disabilities (i.e., DD). The purpose of this article is to briefly review the link between oculomotor control and visual attention processes and ASD, and to discuss the specificity and overlap of eye movement findings between ASD and other neurodevelopmental disorders.

Authors: Peña Miranda David Daniel , Serra Cantallops Antoni , Muñoz González Rubén Darío
Published: February 2017

A pesar del interés generado por el estudio de la responsabilidad social empresarial (RSE) en el mundo académico, el concepto aún no ha sido acogido de manera uniforme; incluso ha generado un gran número de definiciones que han creado confusión en su aplicación. Utilizando esta realidad como punto de partida, este artículo pretende contribuir al análisis, discusión y construcción de modelos epistémico-prácticos para permitir una mejor comprensión del concepto de la RSE y, más concretamente, de las prácticas que se realizan mediante empresas bajo la atenta mirada de los diferentes grupos de interés en la sociedad. Después de una extensa revisión a la literatura y una aplicación de los métodos de analogía, análisis y síntesis, el artículo aporta una nueva definición de RSE como contribución a su propia construcción, seguido de una propuesta universal para la clasificación de empresas según sus prácticas de RSE.

Sistematización de la experiencia de la estrategia De Cero a Siempre en los centros de desarrollo integral en Solita, Caquetá
Authors: Sánchez Castillo Verenice , Gómez Cano Carlos Alberto , Obregón Karen Juliana
Published: February 2017

La estrategia De Cero a Siempre, propuesta y realizada por el Gobierno nacional, permite desarrollar los modelos tradicionales desplegados por el Instituto Colombiano de Bienestar Familiar en pro de la primera infancia del país. Si bien su implementación por medio de los centros de desarrollo integral facilita la ejecución de objetivos, líneas y realizaciones que la componen, no existe conocimiento de su ejecución en los lugares más retirados del país; por ende, fue necesario sistematizar la experiencia en el Centro de Desarrollo Integral Atardeceres y Luceros, en Solita, Caquetá. De Cero a Siempre representó un cambio positivo en aspectos económicos y sociales, ya que permitió que el tránsito de la modalidad hogares comunitarios a los centros ofreciera una mejora para los docentes —en los aspectos económicos— y para los niños —en aspectos sociales—. Además, hizo que la planeación y regulación de los procesos estuviera más organizada y expuso limitantes para la atención integral a la primera infancia, los cuales sirven como retroalimentación para los modelos futuros.

Published: February 2017

Este artículo hace parte del proyecto de investigación “Léxico dialectal de la ganadería en Casanare, Colombia”, que tiene como propósitos caracterizar esa comunidad de habla y mostrar los fenómenos lingüísticos usados, su léxico autóctono y su impacto sociológico en esta colectividad llanera. La presente investigación es un estudio dialectal de tipo descriptivo-explicativo con tendencia cuantitativa-cualitativa; aquí se describe de manera teórica y empírica la predisposición del uso de expresiones dialectales. Una vez realizado el análisis, se encontró que el uso de los términos dialectales de la ganadería en Casanare (Colombia) se convirtió en un recurso retórico, que cumple funciones pragmáticas de acercamiento del emisor a sus interlocutores; asimismo, que las variantes, la sinonimia y la polisemia son una característica común a muchas de las piezas léxicas que presentan varias alternativas para referirse a lo mismo.
La dicotomía guerra/paz en los videos de la campaña de reelección presidencial de Juan Manuel Santos (Colombia). Análisis de las estrategias de legitimación
Authors: Mendoza-Escalante Alfredo
Published: February 2017

El objetivo de esta investigación fue analizar los videos propagandísticos de la campaña presidencial de Juan Manuel Santos, presidente reelecto en Colombia para el periodo 2014-2018, para determinar y caracterizar las estrategias de legitimación que permitieron lograr la adhesión de los votantes. La presente investigación es mixta, como técnicas se emplearon la observación no participante y el análisis de contenido; y los instrumentos que cada una ofrece, respectivamente, tales como libretas de apuntes y un esquema de análisis que permite determinar las unidades y categorías de análisis. El análisis de los resultados da cuenta de que las estrategias de legitimación presentes en los videos ayudan a delimitar la identidad de un grupo (en oposición a otro), asociar valores morales a cada uno, utilizar marcos simbólicos y recursos retóricos para sustentar las representaciones que se hacen de cada actor (o grupo), apelar a argumentos de autoridad y emplear una forma prescriptiva, para lograr configurar e influir en la opinión pública.
Constitución de la lengua española o castellana
Authors: Ávila Bayona Miguel Ángel
Published: February 2017

Tras la conquista y colonización españolas, los pueblos subdesarrollados de América debieron asumir la lengua de sus conquistadores. Era la lengua que el reino de Castilla ya había impuesto a otras provincias ibéricas (nombre griego), con excepción de la portuguesa. Esta lengua recién estaba alcanzando rigurosidad gramatical, como consecuencia de la evolución del latín impuesto por los romanos desde el año 19 antes de Cristo en la Península Hispánica. Década tras década el latín se alteró en su fonética, morfología, sintaxis y semántica hasta obtener diversos dialectos; algunos, como el castellano, se distanciaron de su lengua madre y se hicieron lenguas con sus propias gramáticas. Las posteriores invasiones, visigodas y árabes, apenas dejaron huella en el castellano, porque los hispanos (nombre romano que significa tierra de conejos) poseían una cultura más sólida que la de sus invasores. El español que hoy se habla procede del latín hablado tanto por la gente culta y por el vulgo o pueblo de entonces, como del ‘bajo latín’ hablado y escrito en la Edad Media (siglos V-XVI). Cada uno en su espacio y momento fue responsable de cambios fonéticos, morfológicos, sintácticos y semánticos. Hoy la evolución prosigue, pese a la universalidad y el enriquecimiento de los medios de comunicación lingüísticamente unificadores.

O trabalho do ator sobre si mesmo: memória, ação, linguagem e silêncio
Authors: Copeliovitch Andrea
Published: February 2017

O estudo da trajetória de Stanislavski e de suas experiências sugere uma reflexão sobre o que é e como é realizar pesquisa em teatro. Para Stanislavski essa pesquisa se dá no “si mesmo” do ator”. Pesquisar o si mesmo é pesquisar a vida inteira; no caso do teatro, é  fazer a vida acontecer na cena. O acontecimento da vida no palco é o acontecimento desse si mesmo com todas as suas complexidades; é tornar-se linguagem própria à cena. O "si mesmo", em constante transformação na impermanência do tempo, constitui seu repertório de vivências e revivescências e nos traz questões fundamentais como memória, ação, linguagem e silêncio.

Published: February 2017

Abstract.  The objective of this research was to evaluate the effect of ensilage technology (with and without ensilage) and protein sources (plant and animal) in complete feed with ramie-waste on nutrient composition and ensilage parameter. Ensilage process decreased significantly dry matter (DM), organic matter (OM) and neutral detergent fiber (NDF), but it increased  ensilage parameter i.e. acetate acid (C2), propionic acid (C3), butyric acid (C4), lactic acid (LA), and decreased pH. It also had non-significant effect on crude fibre (CP), acid detergent fiber (ADF) and ammonia (NH3-N). Animal protein source in silage making decreased nutrient composition i.e. OM and CP and ensilage parameter i.e. C2, but it increased NH3-N.  Interaction between ensilage treatment and protein sources affected CP and pH also ensilage parameter of C2 and C3. In conclusion, plant protein used in silage of complete feed with ramie waste was better than animal protein, despite that both ensilage were not better due to pH over 4.5. Key words: ramie, ensilage technology, protein source, nutrient composition, ensilage parameter Abstrak. Penelitian ini bertujuan mengevaluasi pengaruh teknologi ensilage (dengan dan tanpa ensilage) dan sumber protein (nabati dan hewani) pada complete feed menggunakan limbah rami terhadap komposisi nutrien dan parameter ensilage. Perlakuan teknologi ensilage menurunkan komposisi nutrien pada bahan kering (BK), bahan organik (BO) dan neutral detergent fiber (NDF, meningkatkan kuantitas parameter ensilage pada asam asetat (C2), asam propionat (C3), asam butirat (C4) dan asam laktat (LA) dan menurunkan pH serta tidak nyata pada protein kasar (PK), acid detergent fiber (ADF) dan ammonia (NH3-N).  Perlakuan sumber protein menurunkan nutrien BO dan PK dan C2 serta meningkatkan konsentrasi NH3-N secara sangat nyata pada complete feed dengan protein hewani. Interaksi kedua perlakuan berpengaruh pada PK dan pH serta C2 dan C3. Kesimpulannya adalah penggunaan protein nabati pada silage complete feed menggunakan limbah rami lebih baik dari pada yang menggunakan protein hewani meskipun kedua jenis silage tidak lebih baik karena pH lebih dari 4,5. Kata kunci: rami, teknologi ensilage, sumber protein, komposisi nutrien, parameter ensilage

Authors: Prayitno Caribu Hadi
Published: February 2017

The objective of the study was to evaluate the effect of Heit-Chrose (HC) supplementation using in vitro method on ruminal fermentation of dairy cattle. HC is a feed supplement containing allicin, saponin and organic minerals ( Se , Cr and Zn).  This research was conducted using completely randomized design, with 6 treatments and 4 replications. The treatments were : 1). C = dairy cattle feed (CP 15.38%, CF 23.38%, TDN 61.26%); 2). HC-0 = C+  organic minerals (0.3 ppm Se + 0.15 ppm Cr + 40 ppm Zinc-lysinat) + 0 ppm of HC; 3). HC-15= C + 15 ppm HC; 4).HC-30 =C+ 30 ppm of HC; 5). HC-45 =C+ 45 ppm of  HC; 6). HC-60 =C  + 60 ppm of HC. Data obtained were analyzed using analysis of variance of SPSS program. HC supplementation increased the DMD, OMD, VFA, but reduced  total gas,  methane and  protozoa count.  HC supplementation greater than  30 ppm  did not further improve ruminal fermentation. Supplementation at 30 ppm of  HC to dairy cow feed was the appropriate level to improve the efficiency of rumen fermentation.

Authors: Sugiarto Moch , Ahmad Abdul Aziz
Published: February 2017

The objective of this study was to describe the structure of household’s income of goat farmer and analyze the distribution of goat farmer household’s income in Banjarnegara. For this analysis, Banjarnegara district was divided into three agro ecological zones on the basis of altitude, i.e. low, medium and high land. 180 goat farmers were selected using multistage sampling and data were measured using descriptive statistic and Gini Coefficient. The study concluded that goat farming as a side job contributed 29% of total household income. The income from non-goat farming remain dominating a structure of household income by 71%. There was a high inequality household income among goat farmers with Gini Coefficient of 0.562. The high level of total income inequality was due to a greater relative inequality in non-goat farming income. Since there was a relationship between farm size and income, increasing the number of goats must be actualized to the goat farmers with no other livelihood. This would be able to reduce inequality of total income of goat farmers.

Published: February 2017

Although humic substances consist mosly of humin (65%), however its characteristic in Cu(II) odsorption is not yet clearly revealed. In this work, humin was isolated from peat soil of west Kalimantan, purified and then interacted with Cu(II). The purity of isolated humin was determined by its ash content. The funtional group in this purified humin was characterized qualitatively by FTIR and quantitatively by titration. Study on the solubility of Cu(II) in freshwater was carried out at pH from 2-12 in the presence and without purified humin. To obtain adsorption kinetic parameters of Cu(II) on humin in freshwater, study based on Langmuir-Hinshelwood was carried out, while for its thermodinamics parameters, a study based on Langmuir and Freundlich were employed.The ash content of purified humin was 1,58 % (w/w), it showed that the humin was in pure condition. The active fungtional group identified humin were –COOH (1700 cm-1) 115 cmol/kg and –OH fenolic (3421,5 cm-1) 562 cmol/kg.

Direct oxidation of eugenol has been done using potassium permanganate. This research attempts to produce benzyl carboxylic acid, an important intermediate reactant for isoflavone synthesis, directly by breaking the p bond of allillic group attached to eugenol. The oxidation procedures were adopted from Wahyuningsih and Kusumaningsih anetol oxidation reactions. There were three modifications done i.e. one polar system of the oxidation environment, variation of time of reflux and temperature. Eugenol was firstly diluted in water by converting to its salt type and then oxidized using KMnO4 at 75 oC for 4 hours. The expected acid was separated by acidifying using sulfuric acid.The result showed that direct oxidation of eugenol using modified method of Wahyuningsih gave only a vicinal diol which undergoes polymerization into product in 80% yield with 83% purity. However, variation of time of reflux of Wahyuningsih method showed the same result with Kusumaningsih method as brown oily viscous liquid. The product was only 38% purity.
