Authors: Pott Terilyn
Published: October 2015

This exploratory study was undertaken to learn more about how mature students perceive the career counselling process in a post-secondary institution. Through the use of critical incident technique this study examined how three mature students interpret their relationship between themselves and their counsellors. Significant factors identified as contributing to a positive interpersonal connective bond were considering the whole of the clients’ experience, integrating career and personal concerns, introducing assessment tools appropriately, and utilizing counsellor self-disclosure appropriately. This study highlights the importance of utilizing critical incident technique in career counselling, the importance of the working alliance for mature students, and identifies possible counselling applications to consider when working with this population.

Published: October 2015

The antivascular endothelial growth factor (VEGF) ranibizumab (Lucentis) and aflibercept (EYLEA) and the intraocular corticosteroids dexamethasone (Ozurdex) and fluocinolone acetonide (ILUVIEN) are approved for treating diabetic macular edema (DME) in the US. Here, we review each therapy and consider the advantages of administering a corticosteroid as a slow-release implant. A suboptimal response is seen in about 50 % of DME patients treated with anti-VEGF therapy. In such patients corticosteroids are an attractive alternative. Treatment with a course of corticosteroids to indicate if a clinically significant rise in intraocular pressure may occur is required before commencing ILUVIEN. Then the physician can make a clinical decision on the treatment. ILUVIEN offers the advantage of providing 36 months of drug release from a single implant. With the availability of four drugs to treat DME, it is important to consider the optimal treatment for the individual patient.
Importance of Performing Corneal Topography Before Cataract Surgery
Authors: Loh Jennifer ,   Ophthalmologist, South Florida Vision Associates, Fort Lauderdale, Florida, US
Published: October 2015

Corneal topography assessment has become increasingly important for surgical planning in patients scheduled for cataract surgery. One of the main reasons is the increased expectations for reduced spectacle dependence following cataract surgery, whether patients are selecting an advanced technology intraocular lens (ATIOL), such as a toric or multifocal IOL, or even when choosing a monofocal IOL Preoperative topography enables surgeons to determine whether a patient is an appropriate candidate for an ATIOL, and also enables surgeons to identify corneal conditions that are contraindications to certain types of IOLs, especially as many corneal conditions are not visible on slit lamp exam. This article will focus on the value provided by preoperative corneal topography prior to cataract surgery and discuss clinical situations where it has been critical in guiding IOL selection.

Nowadays, Autonomous carrier vehicles are becoming more predominant for the modern society. Hence designing these vehicles is one of the core fields of automation engineering. In regard to that, our project full-fills an idea of autonomous transportation. This vehicle is a carrier of materials from one place to another place through a fixed lane Path (guide way). It can also act as an easy vehicle for disabled and blind people in their houses.The main carrier consists of a table mounted on four omni-wheeled base which has control unit which guides the direction of the wheels. The carrier has an insert which moves through a guide keyway. Each junction and turning points has proximity sensor which indicates the position of carrier to the controller. The microcontroller is programmed in such a way that it can find the direction that the bot has to move at every junctions. This was programmed by considering the shortest path between the current position and the destination point. The controlled signal is amplified and made to actuate the motor control relays.Carrier bot is operated wirelessly using RF remote which has the position buttons. Those buttons are assigned as the positions. These are the positions that the sensors were built. When we call the bot to a point by pressing the corresponding button it can arrive to that point from any positions and it can autonomously find its way to there and can be sent to any position in a similar way. It can find its applications in a variety of area so as stated as multi-purpose carrier, ranging from hypermarkets to hospitals and libraries to warehouses. In hotels and restaurants it can be employed to serve the food as a servant.
Performance Analysis of Electrolytic and Film Type Capacitor
Authors: Bavithra R , Abarna B
Published: October 2015

This paper deals with the performance analysis of electrolytic and film capacitor in three phase inverter with focus of frequency aspect in ripple current. High capacitance density but low ripple current is produced in electrolytic capacitor alone in DC link of three phase inverter, which degrades the performance of life span of electrolytic capacitor. In order to overcome this problem, Hybrid connection type of capacitor bank is used in order to increase the life span of electrolytic capacitor. A film capacitor is connected parallel with electrolytic capacitor.Film capacitor has, low capacitance density, high ripple current and very reliable. From this combination, electrolytic capacitor has slow absorption of energy whereas film capacitor has absorption of high frequency harmonic. This combination makes longer life span for electrolytic capacitor. In meantime, it reduces the capacitance losses, heating and hotspot temperature rise in electrolytic capacitor. In this paper, analysis of film and electrolytic capacitor is done in MATLAB software and its results are compared.
Line Current Harmonic Reduction in AC-DC PWM Converter Using Genetic Algorithm
Authors: Ibrahim A. Dawood
Published: October 2015

In this paper, AC/DC converters are widely used to get regulated power supply for battery charging and DC motor speed control. SCR converters are preferred in the field of High voltage DC energy transmission, superconductor magnetic energy storage, etc. However these converters have low power factor and also result in higher order harmonics.This paper proposes the application of Genetic algorithms (GAs) to find the switching angles for line current harmonic reduction in AC/DC type converter. Harmonic reduction is redrafted as an optimization problem and GA is applied.The harmonic elimination methods used in AC/DC converters are similar to those employed in PWM inverters or in AC choppers. The solution is obtained using genetic algorithm tool in MATLAB. The dual objectives of harmonic elimination and output voltage regulation are reframed as an optimization task and the switching instances are identified through the steps of GA.
Induction of salt stress tolerance in cowpea [Vigna unguiculata (L.) Walp.] by arbuscular mycorrhizal fungi
Authors: Abeer Hashem , Allah E.F. Abd , Alqarawi A.A. , Egamberdieva Dilfuza
Published: October 2015

The aim of present study was to examine the effect of arbuscular mycorrhizal fungi (AMF) on the growth, lipid peroxidation, antioxidant enzyme activity and some key physio-biochemical attributes in cowpea (Vigna unguiculata [L.] Walp.) subjected to salt stress. Salt stress (200 mM NaCl) reduced growth, biomass, relative water content and chlorophyll pigment content in cowpea leaves. AMF ameliorated the negative impact of salinity on the growth parameters studied. The activity of antioxidant enzymes such as superoxide dismutase (SOD), catalase (CAT), ascorbate peroxidase (APX), peroxidase (POD) and glutathione reductase (GR) enhanced under salt stress and AMF inoculation further enhanced their activity, thus strengthening the plant’s defense system. Proline content increased in salt stressed plants as well as AMF-inoculated plants providing efficient protection against salt stress. Besides this AMF also increased uptake of mineral elements which have direct impact on the osmoregulation of the plants. The present study shows that AMF possesses the potential to enhance salt tolerance of cowpea.

Authors: Kaur Jagmeet , Ram Hari , Gill B S , Kaur Jasdeep
Published: October 2015

A field experiment was conducted at the Punjab Agricultural University, Ludhiana (36°56' N, 75°52' E and altitude 247 m), India during rainy seasons of 2006 to 2008 in split plot design. Experiment comprised of twelve treatment combinations with four plant growth regulators application (salicylic acid @ 50 mg/l, ethrel @ 200 mg/l, cycocel @ 500 mg/l and water spray) in main plot and three stages of application time (at flower initiation, pod initiation and flower + pod initiation) in sub plot, was replicated thrice. Pods per plant in cycocel @ 500 mg/l were significantly higher than ethrel, salicylic acid and water spray. Ethrel 200 mg/l recorded seed yield statistically on par with salicylic acid 50 mg/l but significantly higher than water spray and lower than cycocel 500 mg/l. Pods per plant with plant regulators application at flower + pod initiation were significantly higher than flower and pod initiation. Application of growth regulators at flower and pod initiation gave significantly higher seed yield than flower and pod alone in 2006. On pooled mean basis growth regulators at flower + pod initiation gave 4.9 and 7.7% higher than at flower initiation and pod initiation respectively.

Authors: Krishnamurthy D. , Goudar P. V. Kenchana , Keerthi C. M. , Babu H. Prashanth
Published: October 2015

A population consisting of 147 RILs derived from the cross TG 49 x GPBD 4 and their reverse cross consisting 20 RILs respectively (F7 generation) were utilized for the study. Both the populations were subjected to phenotyping for quality traits (oil content and protein content), disease resistance (rust and LLS both at 70 and 80 days after sowing) and three productivity traits (pod yield/plant, 100-seed weight and shelling %) for kharif 2009. In both the segregating populations, the analysis of variance indicated significant variation for all the yield traits and diseases, but the variation was found to be less for quality traits. High genotypic and phenotypic variation was observed for pod yield (kg/plant), shelling per cent, rust and LLS at stage I it indicates the presence of considerable amount of genetic variability for these traits whereas in oil content and protein content there is low GCV and PCV. There was a highly significant and positive correlation between the protein and oil content in GPBD 4 x TG 49 population but negative relation in the TG 49 x GPBD 4 population. Highly significant positive correlation was observed in 100-seed weight and pod yield per plant in both the population indicating that breeding for high yield can be achieved without comprising the large seed size, which is a preferred trait for confectionery groundnut. Several RILs superior to best parent were identified for different traits which could be utilized in future breeding programmes.

Published: October 2015

An experiment was conducted at Nonaghata-Uttarpara village under Haringhata block in Nadia district during successive rabi seasons of 2007-08 and 2008-09 to study the arsenic contamination in vegetable pea cv. Karishma and to explore possibilities of offloading the accumulation through nutrient management using harvested surface water for irrigation. The experiment has been laid out with two irrigation sources in main plot I1: irrigation from Shallow Tube Well (STW) and I2: irrigation from Pond Water (PW) and four nutrient management options in sub-plot [N1: 100% RDF (60-80-90 kg ha−1 N, P2O5 and K2O), N2: 100% RDF with double the recommended dose of phosphate, N3: 75% RDF + FYM @ 10 t ha−1, N4: 75% RDF + FYM @ 10 t ha−1 with double dose of phosphate] in a split plot design, replicated three times. Results revealed that pod yield did not significantly vary with different irrigation sources, but arsenic accumulation and uptake was the lowest with irrigation from harvested rain water i.e. pond water. 75% RDF + 10 t ha−1 of FYM with increased phosphate recorded the maximum yield with the least arsenic accumulation (N4).
La enseñanza de nuevas palabras en situaciones de enseñanza de ciencias sociales. Un estudio en escuelas primarias de Argentina
Authors: Menti Alejandra , Rosemberg Celia Renata
Published: October 2015

El presente trabajo tiene por objeto analizar cuán familiares a los alumnos son las palabras que configuran el entorno lingüístico al que se hallan expuestos durante las clases de ciencias, así como también describir los movimientos conversacionales que emplean los docentes durante el tratamiento del vocabulario poco familiar a los niños. El corpus está conformado por 12 situaciones de enseñanza registradas en clases de ciencias en 1er., 3er. y 5to. grado de cuatro escuelas -dos urbanas y dos rurales- de la provincia de Córdoba, Argentina. Se diseñó y aplicó una escala a partir de la cual se valoró el grado de conocimiento que los alumnos tenían de las palabras que configuraban el entorno lingüístico de las clases. El análisis de los datos se realizó mediante el empleo combinado de procedimientos cuantitativos y cualitativos. Los resultados cuantitativos mostraron que los alumnos de 3er. grado tuvieron menos oportunidades de escuchar palabras poco familiares que los de 1er. No se registraron diferencias significativas con 5to. grado. Tampoco se observaron diferencias entre las escuelas rurales y urbanas. El análisis cualitativo mostró que al introducir una palabra poco familiar a los niños, las maestras mejoren la comprensión de su significado mediante movimientos de reparación y actos discursivos de expansión y ejemplificación. Asimismo, se focalizan en el vocabulario poco familiar de manera explícita e implícita y proporcionan distintos tipos de información para que los alumnos puedan comprender su significado. Los resultados del estudio tienen importantes implicancias pedagógicas en tanto muestran la necesidad de incrementar, a lo largo de la escolaridad primaria, las oportunidades de aprendizaje de vocabulario poco familiar a los niños, ya que la amplitud del vocabulario infantil es un predictor de la adquisición del sistema de escritura, como así también de la comprensión y de la producción de textos.
Integración de las TIC para una “buena enseñanza”: opiniones, actitudes y creencias de los docentes en un instituto de formación de formadores
Authors: Rombys Estévez Diego
Published: October 2015

El presente estudio aborda las opiniones, actitudes y creencias de los docentes de un instituto de formación magisterial acerca de la integración de las TIC en la educación.La investigación corresponde a un enfoque cualitativo descriptivo que emplea varias técnicas asociadas, en general a un estudio de caso. Entre ellas destacamos como herramienta principal el uso de entrevistas, incluyendo el empleo de imágenes para evocar recuerdos y sentimientos, así como técnicas complementarias que incluyen un cuestionario. A partir del análisis de la literatura se perfeccionaron dichos instrumentos y, posteriormente, se triangularon dichas técnicas.Entre los principales hallazgos de esta investigación se constató que quienes presentan enfoques educativos centrados en la enseñanza tienden a considerar de forma más crítica a las TIC. Complementariamente, se identificaron otros aspectos como, por ejemplo, que quienes están dispuestos a aprender acerca del uso de las TIC “con y de los alumnos” presentan actitudes más proclives a incorporar estas tecnologías que quienes creen que ello significa una pérdida de autoridad y afecta su autoestima. Algo similar ocurre en relación a cómo consideran que las TIC afectan al empleo tradicional de los libros.En las reflexiones finales se incluyen sugerencias para enfrentar con mayores posibilidades estos desafíos, y construir adecuados equilibrios a partir del aporte de los docentes a los efectos de contemplar las diferentes visiones que hacen a una “buena enseñanza”.En cuanto a la oportunidad de esta investigación, basta mencionar que en virtud del Plan CEIBAL en los próximos años irán llegando progresivamente a las instituciones de formación las primeras generaciones “criollas” de “nativos digitales” para formarse como maestros. En dicho marco esperamos que puedan desarrollarse como docentes sin barreras conceptuales que limiten sus oportunidades y las de sus futuros alumnos.
Clima escolar y tipología docente: la violencia escolar en las prácticas educativas
Authors: Rojas Bravo Jorge Manuel
Published: October 2015

La violencia escolar actualmente es una temática de preocupación pública y privada. En este sentido, en Chile se han organizado una serie de seminarios, propuestas y acciones en torno a la modificación de este problema sociológico con tintes de problema social. Sin embargo, el paradigma que ha primado en la observación del problema se ha sobre-enfocado en los aspectos individuales: “los estudiantes abusivos” o su contrapartida, “la víctima indefensa”. Sin duda que esta mirada es cierta, pero no podemos ver el problema sólo desde esta perspectiva. De hecho en los análisis sobre las determinantes del nacimiento de la violencia y sus manifestaciones, no sólo la podemos apreciar desde “la familia” o las características personales de los estudiantes, sino que nuestra mirada se dirige hacia la institución escolar misma. La violencia escolar ha estado desde siempre en el sistema educativo, sin embargo, las viejas prácticas de disciplinamiento y control del estudiantado pocas veces se observan como tales. El objetivo principal del estudio es analizar aquellas prácticas educativas de cuatro escuelas primarias, que pueden ser conceptualizadas como violentas, y que precisamente se han invisibilizado como tal. La metodología utilizada fue de corte etnográfica, en la que se utilizaron 160 observaciones participantes y 16 entrevistas semi-estructuradas. Los espacios de observación fueron cuatro salas de clase, principalmente la interacción profesor-alumno. Los principales resultados permiten comprender cómo ciertos aspectos de las dinámicas o estáticas mismas de las prácticas escolares generan espacios de continua violencia tanto implícita como explícita hacia los estudiantes y que los climas que se crean no son los más aptos para el aprendizaje de los valores sociales que promueven nuestras reformas educativas. A partir de esta lógica se logró determinar distintos escenarios y tipologías de docentes que contienen distintas formas de violencia en sus prácticas pedagógicas y los climas de aula que generan. De esta forma, tenemos tres tipos de escenario posibles y tres tipos de docente observados.
La lectura como práctica sociocultural y herramienta para lograr la equidad social a partir de la enseñanza. Discusión acerca la enseñanza de la lectura
Authors: Silveira Caorsi Edith
Published: October 2015

Este trabajo surge de la reflexión acerca de la enseñanza de la lectura en el sistema educativo uruguayo a partir de mi participación en el equipo de ProLEE de Codicen en el año 2011. Es parte de los desafíos y las preguntas que se nos plantearon como equipo. En él aparecen cuestiones referidas a la enseñanza de la lectura como actividad institucional. En esa búsqueda y en esas discusiones decantaron las ideas que aquí expongo para mejorar la enseñanza y a potenciar los aprendizajes cargándolos de significación.Parto de la base de que el aprendizaje de la lectura es el fundamento de la enseñanza académica ya que la alfabetización es la llave de entrada a la cultura institucional. Me pregunto acerca de los modos y las prácticas de la enseñanza de la lectura.En la escuela, como agente universal del acceso a la cultura escrita, se realizan prácticas pedagógicas y existen representaciones sociales sobre el asunto. La enseñanza de la lectura es una instancia cruzada por tensiones históricas, sociales y políticas.El trabajo se propone polemizar acerca de las prácticas actuales y se pregunta sobre la necesidad de una nueva narrativa que construya una epistemología y una metodología acordes a una acción basada en aspectos socioculturales con el aporte de otras ciencias sociales. Invita a desarrollar la investigación cualitativa en relación con el estado y a revisar las categorías establecidas. El objetivo de esta búsqueda es lograr una acción más eficaz en los diferentes contextos pedagógicos y potenciar la adquisición de la llamada literacidad crítica la autonomía del lector en diferentes contextos pedagógicos.

Published: October 2015

A pesar de haber sido objeto de cambios y transformaciones recientes, las estructuras, planes y normas que organizan los sistemas de formación docente inicial y continua en los países del Mercado Común del Sur (MERCOSUR) siguen en debate. En este contexto se plantea el desafío de encontrar puntos de articulación que contribuyan a la integración regional de los países del bloque y a la movilidad de los docentes.Si bien la currícula y los programas de formación continua constituyen sólo una parte o dimensión del complejo proceso de la formación docente, su análisis y comparación resultan relevantes y oportunos toda vez que se pretende mejorar la preparación de los maestros y profesores. En este marco cabe preguntarse cuáles son las principales tendencias que caracterizan a las propuestas de formación en la región.El artículo resume los principales resultados alcanzados a través de un estudio llevado a cabo a solicitud del Programa de Apoyo al Sector Educativo del Mercosur (PASEM) cuyo propósito fue comparar los planes de formación docente inicial así como la oferta y organización de la formación continua existente en los siguientes países miembro-fundadores del MERCOSUR: Argentina, Brasil, Uruguay y Paraguay.La metodología seguida se focalizó en el relevamiento y análisis comparado de los documentos, lineamientos y programas de formación inicial y continua. Se trabajó en base a una serie de problemas, dimensiones y categorías de análisis con el objetivo de destacar aspectos compatibles y otros singulares que fueran significativos tanto a los fines de la integración como al mejoramiento de la formación docente.

Formación del gestor universitario en algunos países latinoamericanos
Authors: Artiles Rodríguez Josué , Rodríguez Pulido Josefa , Santana Sánchez Anotnio
Published: October 2015

Cada vez más, los gobiernos delegan la responsabilidad de los cambios y mejoras de las instituciones de educación superior en sus directivos. Preocupados por la necesidad de formación que éstos deben adquirir, hemos considerado de interés llevar a cabo una primera aproximación al conocimiento de la oferta formativa universitaria para la gestión de estas instituciones en algunos países de Latinoamérica. El trabajo se planteó con un doble objetivo.En primer lugar, se indagó en las características generales de la formación de los gestores: cuáles son los requisitos de acceso, qué miembros de la comunidad universitaria tienen acceso a dicha formación, cuál es su temporalidad, qué cuantía económica aporta el interesado que accede a dicha formación. Asimismo, se consideraron los objetivos que persiguen los distintos centros y el momento de desarrollo en el que éstos se encuentran. En segundo lugar, nos interesamos por algunas características específicas como las modalidades de formación desplegadas, las estrategias utilizadas y las competencias a desarrollar. Para la recolección de la información se confeccionó un protocolo donde explicitamos las diferentes dimensiones a estudiar en los programas formativos. La información se obtuvo tras un proceso de indagación en los diferentes espacios virtuales, situados en la red, de cada una de las universidades, públicas y privadas, existentes en Costa Rica, Cuba, El Salvador,México y Panamá. Se exploraron 750 páginas web relacionadas con centros, facultades e institutos de educación superior y se evidenció una escasa oferta formativa para el desarrollo de los profesionales de la gestión universitaria en sus distintos niveles de organización.
¿Cómo se aprende la ortografía de las palabras? Un estudio de comparación de distintas estrategias
Authors: Diuk Beatriz , Ferroni Marina , Mena Milagros
Published: October 2015

El presente trabajo se propuso analizar el impacto de diferentes modalidades de aprendizaje sobre la adquisición de conocimiento de la ortografía de las palabras. Para ello, 30 niños que cursaban el 3.er año de la escolaridad primaria participaron de sesiones de aprendizaje de pseudopalabras con ortografía compleja mediante tres condiciones: lectura, lectura más escritura manuscrita y lectura más escritura con fichas. Tres días después de las sesiones de aprendizaje se evaluaba si efectivamente los niños habían podido almacenar la forma ortográfica de las pseudopalabras a las cuales se vieron expuestos. Para ello se administró una prueba de escritura de las pseudopalabras al dictado y una prueba de decisión léxica en la que los niños debían identificar, entre cuatro opciones, los ítems que se les habían presentado en las sesiones de aprendizaje.El análisis de los datos mostró que los niños se desempeñaron por encima del nivel de azar en las pruebas de post- test. La comparación de los puntajes en las distintas condiciones reveló diferencias significativas entre las condiciones de lectura y escritura con fichas a favor de esta última. No se encontraron diferencias significativas entre la lectura y la escritura manuscrita ni entre las dos condiciones de escritura.Los datos obtenidos sugieren que si bien la lectura y la escritura manuscrita constituyen vías para la adquisición de conocimiento ortográfico, la escritura de las palabras con fichas resultó un mecanismo más potente. Se considera que en esta tarea, la búsqueda de cada una de las letras necesarias para formar las pseudopalabras implicaba un uso adicional de recursos atencionales, hecho que impactaría significativamente en el aprendizaje ortográfico.

Un nuevo reto para el comercio exterior peruano: las medidas sanitarias y fitosanitarias
Authors: Valverde Arévalo Marcelo Alonso
Published: October 2015

RESUMEN

El comercio mundial se ha multilateralizado logrando una reducción constante de las medidas arancelarias que lo restringían décadas atrás; sin embargo, los países han encontrado otras medidas que pueden ser utilizadas de manera proteccionista, tales como las medidas sanitarias y fitosanitarias, los obstáculos técnicos al comercio, entre otras. El presente artículo describe y ejemplifica medidas sanitarias y fitosanitarias que han afectado o afectan a las exportaciones peruanas; cómo éstas restringen el comercio y confunden a los exportadores en vez de proteger la salud humana, animal y vegetal.

 

ABSTRACT

World trade has multilateralised with a steady reduction of tariff measures that restricted it decades ago; however, countries have found other measures that can be used in a protectionist manner, such as sanitary and phytosanitary measures, technical barriers to trade, among others. This article describes and exemplifies SPS measures that have affected or affect Peruvian exports; how they restrict trade and confuse exporters rather to protect human, animal and plant health.

Published: October 2015

Los grandes avances tecnológicos se han producido una serie de artefactos electrónicos que mejoran la calidad de vida de la personas. Estos artefactos pueden visualizarse en el hogar como los electrodomésticos, equipos de entretenimiento o dispositivos de seguridad. Actualmente, existe una tecnología llamada domótica que consiste en automatizar los artefactos eléctricos del hogar. Esta tecnología presenta varias soluciones en el mundo, donde cada una tiene distintas maneras de implementación y propósitos. Por eso, los precios de los productos generados por estas soluciones son considerablemente altos para el mercado peruano y latinoamericano. Asimismo, estas soluciones presentan una  carencia de soporte para estos mercados. Por estas razones, este artículo propone la implementación de una solución de domótica que utilizando un modelo definido basado en las mejores prácticas del mercado actual se pueda generar una solución de bajo costo, de gran alcance y que sea económicamente accesible para el mercado peruano y latinoamericano. Para esto se estudiará los actuales métodos de comunicación para la creación de los dispositivos de domótica. Además, se evaluará las soluciones existentes de domótica, obteniendo el conocimiento de sus problemáticas, resultados y recomendaciones para poder tener una base con la cual sustentar las mejoras y ventajas de la propuesta a desarrollar.

Technological advances have created a number of electronic devices that improve our quality of life. These devices can be seen in our home as appliances, entertainment equipment or security devices. A current technology known as domotics or home automation that automatizes home electric appliances. This technology presents various solutions, each with their own implementation and purpose. As such, the products' prices are considerably high for the Peruvian and Latin American markets. Similarly, these solutions have no post-puchase support in these markets. For this reason, this article proposes a domotics solution based on the best practices on the market today that can create a low-cost solution that within the price point for the Peruvian and Latin American market. To do so, we have studied current methods of communication to create domotics devices.
Integrating Health Care for the Most Vulnerable: Bridging the Differences in Organizational Cultures Between US Hospitals and Community Health Centers
Authors: Ko Michelle , Murphy Julia , Bindman Andrew B.
Published: October 2015

Policymakers have increasingly promoted health services integration to improve quality and efficiency. The US health care safety net, which comprises providers of health care to uninsured, Medicaid, and other vulnerable patients, remains a largely fragmented collection of providers. We interviewed leadership from safety net hospitals and community health centers in 5 US cities (Boston, MA; Denver, CO; Los Angeles, CA; Minneapolis, MN; and San Francisco, CA) throughout 2013 on their experiences with service integration. We identify conflicts in organizational mission, identity, and consumer orientation that have fostered reluctance to enter into collaborative arrangements. We describe how smaller scale initiatives, such as capitated model for targeted populations, health information exchange, and quality improvements led by health plans, can help bridge cultural differences to lay the groundwork for developing integrated care programs.
Anamorphic development of Apfelbeckia insculpta (L. Koch, 1867) (Diplopoda: Callipodida: Schizopetalidae)
Authors: Ilic Bojan , Tomic Vladimir , Lucic Luka , Mitic Bojan
Published: October 2015

An overview of the anamorphic development of Apfelbeckia insculpta is
provided. As in other myriapods and arthropods, this period of the life cycle
includes different stages that are separated by molts. Based on an earlier
description of post-embryogenesis of A. insculpta and on our data, we
describe ten stadia that occur after juveniles of our focal species hatch
from the egg. Each molt is accompanied by the addition of podous and apodous
pleurotergites, leg-pairs and ocelli. Thus, the numbers of these structures
can be used as reliable criteria for the separation of post-embryonic stadia
in A. insculpta. Adulthood is reached through teloanamorphosis, i.e., with
the ninth and last molt individuals become sexually mature and achieve
adulthood. Sexes can be distinguished from stadium VIII onward.
Digital Smile Design for Computer-assisted Esthetic Rehabilitation: Two-year Follow-up
Authors: Meereis CTW , de Souza GBF , Albino LGB , Ogliari FA , Piva E , Lima GS
Published: October 2015

Objective: The esthetics of the smile are related to the color, shape, texture, dental alignment, gingival contour, and the relationship of these with the face.

Purpose: To present a two-year follow-up for an esthetic rehabilitation clinical case in which the method of digital smile design (DSD) was used to assist and improve diagnosis, communication, and predictability of treatment through an esthetic analysis of the assembly: face, smile, periodontal tissue, and teeth.

Clinical Procedure: The smile's esthetics were improved through gingival recontouring, dental home bleaching, and a restorative procedure with thin porcelain laminate veneers using lithium disilicate glass-ceramic (e.max Ceram, Ivoclar-Vivadent) laminates on teeth 4 through 13.

Discussion: The proposed technique had an acceptable clinical performance at the end of a two-year follow-up.

Significance: DSD can be used to increase professional/patient communication and to provide greater predictability for the smile's esthetic rehabilitation.
Improving Heterogeneous Catalyst Stability for Liquid-phase Biomass Conversion and Reforming
Authors: Héroguel Florent , Rozmysłowicz Bartosz , Luterbacher Jeremy S.
Published: October 2015

Biomass is a possible renewable alternative to fossil carbon sources. Today, many bio-resources can be converted to direct substitutes or suitable alternatives to fossil-based fuels and chemicals. However, catalyst deactivation under the harsh, often liquid-phase reaction conditions
required for biomass treatment is a major obstacle to developing processes that can compete with the petrochemical industry. This review presents recently developed strategies to limit reversible and irreversible catalyst deactivation such as metal sintering and leaching, metal poisoning and
support collapse. Methods aiming to increase catalyst lifetime include passivation of low-stability atoms by overcoating, creation of microenvironments hostile to poisons, improvement of metal stability, or reduction of deactivation by process engineering.
Simple quasi-common path point diffraction interferometer with adjustable fringe contrast and carrier frequency
Authors: Bai F. Z. , Miao Y. , Guo H. , Gao X.J. , Wang X.Q.
Published: October 2015

This paper presents a simple quasi-common path point diffraction interferometer (PDI) that allows fringe contrast and fringe spatial frequency to be adjusted conveniently. The novel aspect of this PDI is the use of a polarizer with pinhole as the PDI mask - and then, with a compact circular optical setup, reference and measurement waves are obtained. Furthermore, a linear tilting modulation is added into two interfering waves and adjusted easily by tilting the polarizing beam splitter - and hence the Fourier transform method can be perfectly applied to extract the wavefront phase from the captured fringe pattern, with the highest fringe contrast and suitable carrier frequency. Detailed theoretical analysis and experimental results are presented.

Seawater is a complex multicomponent system, which involves varieties of organic, inorganic, dissolved and suspended substances. However, the main components dissolved in seawater are the inorganic salts such as NaCl, MgCl2, KCl, NaHCO3, and MgSO4. These elements make different contributions to the spectra of absorption and scattering in water. In this paper, the spectra of different aqueous solutions were measured in the region from 200 to 1200 nm; the attenuation characteristics of aqueous solutions were studied at wavelengths of 450, 532, and 633 nm, respectively; the relationships between attenuation coefficient and the conductivity in different concentrations were also studied.
Estimation of Microfinance Demand and Supply: With Special Reference to Assam

Published: October 2015

The paper delves to estimate microfinance demand, supply and its mismatch in India in general and Assam in particular. Since exact estimation is a bulky task, it adopts an approximation model based on poverty database, mixmarket database and some complementary reports on microfinance. The study shows that microfinance demand has shown a trend of increasing growth for India as well as Assam and stands its candidature as a potential matured market in future. The supply of microfinance for India as a whole is at low level, which shares only 0.70 per cent of gross domestic product of India. From the regional perspective, southern region dominates the supply of microfinance and Assam shares the least. The study indicates a huge mismatch between demand for and supply of microfinance and considering mixmarket average loan size all the regions of India are deficient in terms microfinance supply. The study further indicates some of the possible reasons for the mismatch.  Int. J. Soc. Sci. Manage. Vol-2, issue-4: 308-314

Modern leadership has permeated the village social system. Change within that system will naturally necessitate a change in the socio -political construct of the leaders. The socio-political construct of a leader has been the resultant of interactive perception and perceptual configuration. In developing countries like India, leaders act as a change agent so far as development of villages and villagers are concerned. It is very important for the leaders to have a modern outlook as well as to be democratically oriented if they have to work in a democratic set up as India claims to be for a sustainable and renewable development of India. The study has been conducted mainly to estimate the socio political structure of the rural leaders as a predicted character in elucidating the leadership dynamics in a given social ecology. Accordingly, 19 different independent variables were included in designing socio-political structure. The present study was carried out with a sample of 100 rural leaders (sociometric leaders and institutional leaders) at Haringhata block I of Nadia district in the state of West Bengal. The purposive as well as simple random sampling and systematic sampling techniques were adopted for the present study. It has been found that the variables like  Occupation (X3), Education (X4), Five Year Plan (X7), Panchayat system perception (X8), Dominance (X9), Self-confidence (X10), Dogmatism (X11), Authoritarianism-equilitarianism (X12), Conservatism-liberalism  (X13), Fatalism- scienticism (X14), Individualism familism (X15), progressive-reactionary (X16), Political ideology (X17 ), Election perception (X18 ), and alienation (X19 ) have contributed immensely towards profiling the political structure of the rural leaders .Thus the whole of the study rightly has come out with a clear indication that for better and effective construction of leadership and unleashing of their function, we need to have a focused and effective training viz  a viz motivational interventions.Int.

The tempo of wageless work
Authors: Millar Kathleen M.
Published: October 2015

This article puts E. P. Thompson's writings on time-sense in conversation with the temporality of work on a garbage dump in the outskirts of Rio de Janeiro, Brazil. At this site, several thousand urban poor (catadores) collect recyclables for a living outside relations of wage labor. The lived experience of “woven time” on the dump, which combines labor with other activities of the everyday, has fashioned what these workers call “a different rhythm of life.” Diverging from other temporalities of neoliberal capitalism, such as “ruptured time,” woven time emerges as an important dimension of a life well lived, as conceived by catadores. Attention to the micro-temporalities of wageless work reveals how precarious forms of labor in contemporary capitalism constitute processes of subject making that both parallel and diverge from the transition to wage labor that Thompson describes in his social history of capitalism.
“The state has replaced the man”
Authors: Koch Insa
Published: October 2015

This article offers an ethnographic analysis of everyday sociality and the welfare state on a council estate in England. Taking the case of means-tested benefits, it investigates how women's encounters with the welfare state come into conflict with their attempts to build and to maintain family homes. It argues that while the current benefit system offers women a minimum safety net, it also comes with a set of expectations about appropriate behavior that is contrary to the fluid and collaborative nature of women's daily lives. Although the article demonstrates that women contest the punitive effects of the policies by subverting the rules of the benefit system, ultimately it suggests that dependence on the benefit system is a deeply coercive experience. Overall, the article not only provides a critical commentary on current policy developments in Britain, but it also contributes more generally to anthropological challenges of normative models of citizenship.
Global privatized power
Authors: Starzmann Maria Theresia
Published: October 2015

The practice of archaeologists and other heritage specialists to embed with the US military in Iraq has received critical attention from anthropologists. Scholars have highlighted the dire consequences of such a partnership for cultural heritage protection by invoking the imperialist dimension of archaeological knowledge production. While critical of state power and increasingly of militarized para-state actors like the self-proclaimed Islamic State, these accounts typically eclipse other forms of collaboration with non-state organizations, such as private military and security companies (PMSCs). Focusing on the central role of private contractors in the context of heritage missions in Iraq since 2003, I demonstrate that the war economy's exploitative regime in regions marked by violent conflict is intensified by the growth of the military-industrial complex on a global scale. Drawing on data from interviews conducted with archaeologists working in the Middle East, it becomes clear how archaeology and heritage work prop up the coloniality of power by tying cultural to economic forms of control.

An experiment was conducted to quantify the chemical composition, different forms of tannins and their effects on in vitro gas production, organic matter digestibility and metabolisable energy content in Syzigium cumini (Blackberry) seed with and without polyethelene glycol (PEG). The DM, OM, ash, CP, NDF and ADF contents of S. cumini seeds were 90.1, 87.6, 2.6, 4.6, 32.9 and 15.5%, respectively. The total phenol, total tannin, condensed tannin and hydrolysable tannin content were 5.89, 4.25, 0.42 and 0.05mg/g seed, respectively. In vitro gas production, organic matter digestibility and metabolisable energy content of S. cumini seed were 54 ml, 42.91% and 6.43 MJ/Kg DM, respectively. Addition of PEG to tannin containing seed was significantly (P<0.05) increased in vitro gas production, OMD and ME content. Higher levels of tannins in S. cumini seed could limit utilization through impaired digestibility and nutrient utilization but the addition of PEG increased all the fermentation parameters studied. It is predictable from the present findings that S. cumini seed could be utilized as natural source of feed additives to alter rumen fermentation parameters especially to protect protein and other nutrients from ruminal degradation, thereby make the nutrients available in the lower tract for higher milk and meat yield.Progress.
