Market and Policy in Argentina: Exploring the Non- Market Strategies and Government in A Hybrid Regime
Authors: Simone Paola De
Published: April 2017

This paper investigates the nature of non-market strategies in the case of expanding business in Argentinian.  Result of the enquiry presents a new conceptual framework that allow us to understand the Argentine reality in a proper manner. The full investigation suggests that in other countries the non-market strategies are being studied, without establishing a discipline. Academic material and specific courses have been developed in the business schools of the universities, but, except in specific and small cases, there is no research field and cases developed in Argentina. The expanded research hypothesis argues that companies in Argentina do not understand how to approach the political decisions of the State of hybrid political regimes in matters that concern them. Companies focus on market logic without understanding the logic of "non-market" environments. 
LIBERDADE E EMANCIPAÇÃO ESTÉTICA EM GIANNI VATTIMO
Authors: Bergamo Maurício Sérgio
Published: April 2017

Mostra algumas da principais considerações de Gianni Vattimo à noção de liberdade e emancipação estética nas sociedades da Era Pós-Moderna. Tal análise é desenvolvida pelo filósofo na Sociedade Transparente que teve a primeira publicação em 1992. Diante das sociedades pós-modernas, caracterizadas pelo profícuo desenvolvimento dos meios de comunicação em massa, Vattimo desenvolve um projeto intelectual, que tem em suas bases analíticas, a influência de importantes nomes da filosofia. Para fundamentar sua proposta filosófica, Vattimo discerne sobre o encontro das múltiplas culturas e subculturas no âmbito midiático. A proliferação de documentários e imagens que manifestam e divulgam, globalmente, na forma de meta-dados, as múltiplas cosmovisões no sistema media, possibilita o (re)conhecimento das infindas maneiras de estar no mundo. É nesse encontro dos múltiplos dialetos que há a possibilidade de liberdade e emancipação estética, se e somente se, a racionalidade e os conjuntos culturais forem desenraizados pelas dinâmicas telemáticas dos pressupostos locais. Nesse contexto, as diversas expressões de vida, as infindas imagens culturais dos inúmeros povos do planeta e a variedade de dialetos que, oscilam na rede informacional na forma de notícias, documentários ou relatos, evidencia a impossibilidade de fundamentação de um belo universal.
A PRIMEIRIDADE E INFINITO NA GRÉCIA ANTIGA E NA AMAZÔNIA
Authors: Silva Adelio Alves da
Published: April 2017

Apresenta a experiência de Primeiridade e ‘Infinito’, como um princípio universal e atemporal. Na história do pensamento, ela surge nos poemas concebidos por Homero (IIíada e Odisseia),  sua ocorrência acontece em qualquer lugar, sem mudar a sua forma, não importa o período histórico. Essa mesma experiência ocorreu quando o poeta Lauro esteve pela primeira vez na Amazônia. Nela ele identificou as mesmas manifestações das experiências, do pastor, do marinheiro e do vigia que compõem os poemas de Homero. Cada representante da cultura da Grécia antiga foi substituído no mesmo poema por um representante da cultura amazônica (índio, barqueiro e ribeirinho) sem alterar a sua estrutura.  Como condição de unidade do poema.
Creating Inclusive EAL Classrooms: How Language Instruction for Newcomers to Canada (LINC) Instructors Understand and Mitigate Barriers for Students Who Have Experienced Trauma
Authors: Wilbur Amea
Published: April 2017

This article draws on my dissertation, “Creating Inclusive EAL Classrooms: How LINC Instructors Understand and Mitigate Barriers for Students Who Have Experienced Trauma.” The article explores some assumptions and understandings that English as an Additional Language (EAL) teachers bring to teaching students believed to have experienced trauma, and illustrates the dilemmas they face in supporting such students in a government-funded and designed EAL program for newcomers. Using the concept of Iris Marion Young’s “Five Faces of Oppression” (1990), the data and ndings of the research for my dissertation are explored, contributing to the discussion on trauma and learning in EAL programs and specifically in relation to adult immigrants and refugees. Cet article puise dans ma thèse « Creating Inclusive EAL Classrooms: How LINC Instructors Understand and Mitigate Barriers for Students Who Have Experienced Trauma ». L’article explore quelques hypothèses et interprétations que véhiculent les enseignants d’anglais comme langue additionnelle (ALA) à l’égard d’élèves qui ont subi des traumatismes d’une part, et il illustre les dilemmes auxquels font face les enseignants en appuyant ces élèves dans le cadre d’un programme d’ALA pour nouveaux arrivants et qui est nancé et conçu par le gouvernement d’autre part. M’appuyant sur le concept des cinq visages de l’oppression de Iris Marion Young (« Five Faces of Oppression », 1990), je me penche sur les données et les résultats de ma thèse, contribuant ainsi à la discussion sur le traumatisme et l’apprentissage dans les programmes d’ALA, notamment en ce qui concerne les immigrants et les réfugiés adultes.
Resilience Through Storytelling in the EAL Classroom
Authors: Geres Koreen
Published: April 2017

English as an Additional Language (EAL) teachers o en become the trusted confidants of students who experienced forced migration. Although teachers are not typically trained to be counsellors or encouraged to take that role, what they do in the classroom can have a great influence on their students’ well-being (Pipher, 2002). In fact, teachers and schools can be major factors in building resilience and creating opportunities for adjustment (Pike, Cohen, & Pooley, 2008). When teachers provide strategies for well-being, youth are more likely to have the capacity to cope with tremendous social, educational, and emotional change. One classroom strategy to promote resilience is storytelling. In addition to storytelling being a viable strategy to encourage language learning (Freeman, Freeman, & Mercuri, 2002) and address emotionally diffcult issues for the writer (Hong Kingston, 2006), hearing youths’ stories can build community support (Theron et al., 2011). This article describes a study to explore how teachers of secondary students who were new to Canada used storytelling and what stories the students wanted to tell. The results of the study are discussed in regard to teachers’ reflections on storytelling with EAL students. Les enseignants d’anglais langue additionnelle (ALA) deviennent souvent les con dents dèles des élèves qui ont subi un déplacement forcé. Même si typique- ment les enseignants ne reçoivent pas de formation ou d’incitation pour devenir conseillers, ce qu’ils font en classe peut avoir une grande influence sur le bienêtre de leurs élèves (Pipher, 2002). En fait, les enseignants et les écoles peuvent constituer des facteurs importants dans l’accroissement de la résilience et la création d’occasions pour l’adaptation (Coventry, Guerra, MacKenzie, & Pinkney, 2003; Ingleby & Watters, 2002; Pike, Cohen, & Pooley, 2008). Quand les enseignants o rent des stratégies visant le bienêtre, les jeunes sont plus aptes à avoir la capacité de faire face aux changements profonds sur les plans social, éducationnel et affectif. Une stratégie pédagogie qui améliore la résilience, c’est celle de raconter des histoires. En plus de représenter une stratégie viable pour stimuler l’apprentissage des langues (Freeman, Freeman, & Mercuri, 2002) et aider le raconteur à affronter des questions difficiles (Hong Kingston, 2006), le partage de récits peut accroitre le soutien de la communauté (Theron et al., 2011). Cet article décrit une étude portant sur l’emploi de récits par des enseignants au secondaire et sur les histoires que leurs élèves, de nouveaux arrivants au Canada, ont choisi de partager. Les résultats de l’étude sont discutés en fonction des réflexions des enseignants sur le partage de récits avec des élèves d’ALA.
Restorative Justice Pedagogy in the ESL Classroom: Creating a Caring Environment to Support Refugee Students
Authors: Ogilvie Greg , Fuller David
Published: April 2017

For many years the Canadian government has been committed to resettling refugees. Recently, this commitment has been expanded, as more than 25,000 Syrian refugees have been admitted into Canada. As refugee students struggle to adapt to a new environment, English as a second language (ESL) educators are called upon to play a significant role in the resettlement process. A ending to the social as well as academic needs of students requires educators to alter the pedagogical approach adopted. Restorative justice pedagogy provides a framework for a ending to these needs by transforming ESL classrooms into safe and caring environments. This article will trace the origins of the restorative movement to the criminal justice system and outline how restorative principles have been applied to school discipline. It will then articulate how these principles could be applied to the ESL classroom to identify student needs and begin the process of healing and community building. Finally, the article will conclude with an example of how restorative justice pedagogy has been applied in a Canadian high school with refugee students. Le gouvernement canadien est engagé à la réinstallation de réfugiés depuis plusieurs années. Cet engagement a récemment été élargi et 25 000 réfugiés syriens ont été admis au Canada. Les élèves réfugiés se lu ent pour s’adapter à leur nouvel environnement et les enseignants d’anglais langue seconde sont appelés à jouer un rôle important dans le processus de réinstallation. Répondre aux besoins sociaux et académiques des élèves exige que les enseignants modi ent leur approche pédagogique. La pédagogie de la justice réparatrice o re un cadre pour adresser ses besoins en transformant les classes d’ALS en milieux surs et accueillants. Cet article retrace les origines du mouvement de la justice réparatrice dans le système de justice pénale et décrit l’application de ces principes à la discipline scolaire. Par la suite, l’article explique dans quelle mesure les principes peuvent être mis en œuvre dans les cours d’ALS pour identifier les besoins des élèves et amorcer le processus de guérison et de développement communautaire. Finalement, un exemple de l’application de la pédagogie de la justice réparatrice auprès d’élèves réfugiés dans une école secondaire au Canada vient conclure l’article.

Emerson-Martí: Rupturas (de) Coloniales
Authors: Flores Cornejo Juan Pablo
Published: April 2017

El presente artículo trabaja la divergencia del pensamiento martiano con respecto a la del filósofo estadounidense Ralph Waldo Emerson, a quien Martí ha sido vinculado y señalado como preponderante en la gestación de la obra culmen Nuestra América. No obstante, la investigación considera el trabajo del pensador José Martí desde la óptica del poscolonialismo y la decolonialidad para hacer notar las diferencias claras de ambos pensadores con respecto a la geopolítica del conocimiento, el discurso de la diferencia y los intersticios desde los cualesambos podrían converger. Se trabajan los textos Muerte de Emerson, Nuestra América, y Placeres y Problemas de septiembre de José Martí, así como el ensayo “Destino” de Ralph Waldo Emerson. Consecuentemente, el pensamientomartiano se establece como inaugurador de la lógica de resistencia colonial, distando de la posición general desde la cual Martí es supeditado a Emerson.

Published: April 2017

A partir de la propuesta del Corredor Biológico Inter Urbano Rio Torres (CBIRT) en el Gran Área Metropolitana de Costa Rica, se evaluó el corredor con el método
del manejo adaptativo. Se realizó una evaluación de los objetos de conservación del CBIRT por medio de información de entrevistas, talleres y muestreos previos y
a partir de ello se desarrollaron estrategias de mitigación de amenazas dirigidas a las situaciones particulares del territorio. Se establecieron tres objetos de conservación a evaluar: la microcuenca del río Torres, la trama verde y las aves. El objeto de conservación con una evaluación de amenaza más alta fue Trama verde, por amenazas como la deforestación y el mal manejo de residuos sólidos. El uso de esta metodología facilitó la priorización y monitoreo de acciones para mitigar amenazas y lograr los objetivos planteados para el corredor.

RESUMEN

Esta investigacion versa sobre cómo se ha desarrollado la internacionalizacion de la empresa paraguaya en el periodo 2002-2012. El objetivo es caracterizar a estas empresas y, de manera general, su proceso de expansion. Para esto se recurre a una investigacion mixta, bibliografica-documental y de campo, con enfoque cualitativo y de nivel descriptivo. Entre los principales hallazgos puede apreciarse que las empresas internacionalizadas del Paraguay son empresas de gran porte, mucha trayectoria en el mercado local y dedicadas principalmente a la produccion de bienes con poco nivel de industrializacion, que buscaron internacionalizarse para ampliar su mercado, generar mayor valor a la empresa y aumentar su tamaño.

 

ABSTRACT

This research focuses on the international development of Paraguayan companies in the period 2002-2012. The aim is to characterize these companies and their process of expansion. Thus, bibliographic and documentary evidence will be used in addition to field research, with a qualitative approach at a descriptive level. Among the main findings, it can be seen that international Paraguayan companies are large companies with a lot of experience in the local market; they are mainly engaged in the production of goods with low level of industrialization; they have sought to internationalize and expand their markets, generate greater revenue and increase their size.

 
Las empresas de servicios en américa latina: Un estudio exploratorio sobre factores de competitividad internacional, obstáculos y políticas públicas. (Service companies in Latin America: an exploratory study about determinants of international competitiveness, obstacles and public policies).
Authors: López Andrés , Niembro Andrés , Ramos Daniela
Published: April 2017

 

RESUMEN

Desde hace tiempo los servicios son un sector dominante en la economía global, puesto que dan cuenta de la mayor parte del producto interno bruto y el empleo, tanto en las economías desarrolladas como en buena parte del mundo en desarrollo. En los últimos años, a su vez, los servicios han incrementado su peso tanto en el comercio internacional como en los flujos de inversiones externas. Si bien las empresas latinoamericanas han comenzado a participar activamente de esta nueva dinámica global y varios de los países de la región muestran un dinamismo apreciable en sus exportaciones de servicios, todavía hay importantes espacios de mejora para profundizar estas tendencias y escalar posiciones.

El presente trabajo se basa en una encuesta a empresas de servicios de América Latina en la que se indagó acerca de la visión de las propias firmas respecto a los obstáculos para el comercio de servicios, así como sobre la cobertura e impacto de las políticas públicas existentes en los países de la región que influyen sobre dicho comercio. De aquí pueden derivarse algunos lineamientos de política útiles para promover el desarrollo de las exportaciones de servicios en Latinoamérica.

 

ABSTRACT

Services have long been a dominant sector in the global economy, since they account for the bulk of gross domestic product and employment, both in developed economies and in much of the developing world. In recent years, in turn, services have increased their weight in both international trade and external investment flows. Although Latin American companies have begun to actively participate in this new global dynamic and several countries of the region show a significant dynamism in their services exports, there are still important spaces to deepen these trends and scale positions. The present work is based on a survey of service companies in Latin America in which they were inquired about their own views about obstacles to trade in services, as well as on the coverage and impact of public policies in force that influence this trade. From this, some useful policy guidelines can be derived to promote the development of services exports in Latin America.
Establecimiento de callogénesis somática en Plantago major e identificación de compuestos con actividad biológica
Authors: Jiménez-Quesada Karol , Garro-Monge Giovanni
Published: April 2017

Ante el creciente interés en el aprovechamiento de las propiedades de las plantas medicinales, el estudio de compuestos bioactivos de las mismas se convierte en un campo de investigación interesante y novedoso, con el cual se busca relacionar y comprender la sinergia entre las sustancias naturales y su impacto positivo sobre la salud humana. Una importante utilidad del establecimiento de cultivos celulares es justamente que éstos ofrecen la oportunidad de analizar a nivel bioquímico el aprovechamiento industrial o clínico que tiene una determinada especie debido a la presencia de ciertos compuestos en sus órganos, con la posibilidad de producirlos a nivel celular e in vitro. En este trabajo se logró la inducción de callogénesis somática partir de la germinación de semillas in vitro de Plantago major, las cuales fueron desinfectadas utilizando un protocolo previamente establecido. Luego se tomaron explantes de hoja (1.0-1,5 cm2) de las vitro plantas y fueron cultivados en medio semi–sólido (M&S), para lo cual se generó una matriz de 28 tratamientos que combinaban diferentes concentraciones de reguladores de crecimiento (2,4-D y TDZ) en medio M&S. A partir de esta matriz se seleccionaron 3 medios de cultivo (M14, M27 y M28) con los mejores resultados tanto en la inducción de callogénesis como para embriogénesis somática. Para la identificación y cuantificación de los compuestos bioactivos presentes en los extractos liofilizados de callos, se realizaron análisis de dos estándares para comprobar su efectividad como marcadores químicos en la cuantificación de verbascósidos e iridoides con base en aucubina en P. major. Los extractos hidro-alcohólicos crudos de P. major, fueron elaborados según los protocolos establecidos por la empresa Laboratorios Lisan. Los mismos se prepararon en una concentración de 10% p/v utilizando etanol al 95%. Con el análisis mediante HPLC para ambos marcadores se generaron señales con línea base estable y buena resolución, siendo más efectivo el de verbascósido, por lo que se continuó con las pruebas necesarias para lograr establecer un protocolo de cuantificación en extractos provenientes de los callos generados. La metodología establecida para la detección y cuantificación de los metabolitos bioactivos en este sistema de callogénesis somática, aún debe ser depurada con base en un solvente de extracción que otorgue estabilidad a los extractos en un período de tiempo determinado.

El cacao es una planta nativa de américa tropical y el Perú ha expandido su área sembrada consideradamente, por lo que es necesario un manejo adecuado del cultivo para obtener rendimientos rentables. Así, el presente trabajo tuvo como objetivo validar la inclusión de Trichoderma endófito y micorrizas en la fertilización orgánica e inorgánica para mejorar el rendimiento y la tolerancia a enfermedades del cacao. El experimento fue localizado en dos zonas productivas del Departamento de San Martín (Juanjui y Lamas), cepas de Trichoderma (T) y hongos micorrízicos arbusculares (HMA) se inocularon en plantas de cacao de 6 a 12 años en conjunto con aplicación de fertilizantes (F) y Guano de isla (G), dispuestos en DBCA con 10 tratamientos (Aplicación de T; HMA; T+HMA; T+F; T+G; HMA+F; HMA+G; T; G). Se evaluó la dinámica de las principales enfermedades en cacao (Escoba de bruja, Moniliasis y Pudrición parda), número de frutos cherelles, número de mazorcas y peso de grano seco. A partir de los resultados, se puede concluir que las zonas de Juanjui y Lamas, presentaron mayor incidencia de Moniliasis y Pudrición parda, respectivamente; explicado por el posible desbalance nutricional en las plantas producido por el exceso y falta de calcio, respectivamente. De forma general, la localidad de Juanjui tuvo mayor rendimiento de granos de cacao en comparación a Lamas. Los tratamientos con mayores rendimientos fueron los que incluyeron la aplicación de HMA y fertilizante inorgánico indicando la sinergia entre factores.
Estudio de la dinámica de polinizadores del cultivo de cacao (Theobroma cacao) en tres sistemas de producción
Authors: Salazar-Díaz Ricardo , Torres-Coto Virginia
Published: April 2017

El presente estudio evalúa sistemas  agroecológicos de producción, la dinámica de insectos polinizadores de cacao, y su relación con el manejo del cultivo y la productividad.

El área de estudio estará comprendida en tres diferentes sistemas de producción, (convencional, orgánico y tradicional), ubicados en la provincia de Limón, Costa Rica. Los sistemas productivos se escogieron procurando buscar los contrastes más fuertes posibles en el manejo agronómico de los mismos.

El método de muestreo se realizó utilizando aspiradores manuales. Esta técnica nos permitió, asegurar la captura de insectos directamente dentro de las flores.

Según diferentes investigaciones, en el cacao, la polinización es llevada a cabo casi exclusivamente por micro dípteros de la familia Ceratopogonidae, entre los cuales, ciertas especies del genero Forcipomyia se encuentran altamente especializadas para polinizar las flores del cacao debido a las características específicas de la estructura morfológica del insecto, nuestros resultados no evidenciaron tanta presencia de esta familia,  solamente se encontraron dos especímenes en el sistema de manejo orgánico. A diferencia de especies de la familia Thysanoptera que fueron los insectos que se encontraron en mayor cantidad en cada una de los tres sistemas de producción. Especies de la familia Cecidoniidae y Sciaridae también fueron encontradas en los tres sistemas de producción.

El sistema de producción tradicional fue el que registró mayor cantidad de insectos capturados, también registró mayor cantidad de flores y mayor cantidad de frutos contabilizados. El sistema de producción orgánica fue la que registró menor cantidad de insectos, flores y frutos.

The Effect of Second Pillar Pension to Old Age Pension: Lithuanian Case
Authors: Medaiskis Teodoras , Gudaitis Tadas , Mečkovski Jaroslav
Published: April 2017

This paper evaluates the Lithuanian second pillar pension system from the point of view of individual participant. The goal of the paper is to evaluate whether the participants who joined second pillar pension system in 2004 and retire at the beginning of the year 2019 made the beneficial decision and increase their retirement income. Three different methods are used by comparing the accumulated values of a second pillar pension based on the fully funded principle with the reduced values in the first pillar pension based on the pay-as-you-go principle. The analysis is based on the historical results and data of pension accumulation of an 12 years period from 2004 until the end of 2015 with forecasted continuation of participation for the 2016-2018 period based on the methodology prepared by the authors. The results demonstrate that participation in the fully funded second pillar pension system, compared with non-participation, may in general be assessed as positive and effective. However, the benefits of participation directly depend not only on investment returns and life expectancy, but also on the long-run indexation of the first pillar old-age pension, which is a highly politically reliant variable. Various presumptions concerning this issue are also discussed in the paper.
Public Debt and Economic Growth in Uzawa’s Two-Sector Model with Public Goods
Authors: zhang wei-bin
Published: April 2017

This paper studies public debt dynamics in a neoclassical growth model. The economy consists of one capital, one service and one public sector. The model is a synthesis of Solow’s growth, Uzawa’s two-sector, and Diamond’s debt models. The public sector supplies services which directly affect productivity of the two sectors and welfare of the population. The government finances public expenditure by taxing the outputs, consumption, wealth income, and wage households. The study focuses on the effects of changes in government’s expenditure, the public sector’s productivity, and different taxes on the dynamics of public debt and economic growth. Comparative dynamic analysis examines the effects of changes in preference and polices.
Research Trends into Support for Families Coping with Dementia in Japan
Authors: Kita Motoko , Yoshida Reiko
Published: April 2017

In Japan, there is a growing need for family support of elderly patients with dementia because the number of sufferers is expected to increase over coming years. We conducted a review of 92 studies into the support provided to the families of patients with dementia in Japan. They were reviewed by care setting, study focus, and study design. Most studies were in home settings, followed by hospital settings, with the fewest in long-term care facilities. A wide range and quality of studies were performed in home settings, including quantitative descriptive and interventional studies; however, qualitative descriptive studies and case studies predominated. We identified a need to perform additional studies to verify support programs at home. Concerning family support in hospitals, studies were mainly performed in relation to early diagnosis of dementia and early discharge from hospital, and we observed a clear need to investigate the development of new support programs. Finally, although the need for family support is estimated to be high in long-term care facilities, we found only a few studies investigating this issue. In particular, more studies are needed on the topic of end-of-life care. To offer support that meets the needs of families in various care settings, there is an urgent need to accumulate evidence about patients and their families in each setting.
Step-by-Step: Statistics
Authors: Saltzer Lori A.
Published: April 2017

The Step-By-Step series originated in the fact that students simply don’t need another textbook on Algebra, Calculus, etc. There are already wonderful textbooks on the market in almost every area of mathematics and science. What struggling students do need are more detailed, worked examples than are normally found in even the best textbooks. To solve this problem, every book in the Step-By-Step series contains hundreds of problems with both answers and detailed, worked solutions.

In this volume, Step-By-Step: Statistics, each of the major concepts in a standard Statistics course is given its own section and problems. After a list of the problems for a concept, the answers are given so that students can compare their answers to the correct ones. Following the answers are detailed, worked solutions to each problem. The answers are given first because many students do not want to see a worked solution immediately upon finding that their answer is not the correct one.

Our sincere hope is that this book will aid you in your goal of attaining both a higher course grade and a deeper understanding of Statistics.
EVOLUÇÃO DOS PADRÕES GRÁFICOS ANTROPOMÓRFICOS DEFINIDOS PARA A MICRORREGIÃO DO CARIRI OCIDENTAL, PB

Published: April 2017

A presente pesquisa tem como objetivo remontar a evolução de cinco padrões gráficos antropomórficos pré-históricos definidos para a Microrregião do Cariri  Ocidental paraibano. Esses padrões apresentam características próximas aos já determinados para a região Nordeste, inseridos em duas tradições rupestres: Nordeste e Agreste. Baseado nessas proximidades e se utilizando da análise cladística foi possível a observação, em termos locais, da evolução dos padrões definidos, possibilitado a criação de hipóteses de dispersão dos mesmos dentro da área pesquisada. Os resultados também oferecem subsídios para a confrontação das hipóteses de dispersão da Tradição Nordeste para o semiárido nordestino, conforme já discutido por alguns autores. EVOLUTION OF ANTHROPOMORPHIC GRAPHIC PATTERNS DEFINED FOR THE CARIRI OCIDENTAL MICROREGION, PB ABSTRACTThe present research aims to trace the evolution of five prehistoric anthropomorphic graphic patterns defined for the Cariri Ocidental Microregion, state of Paraíba, Brazil. These patterns present characteristics close to those already determined for northeastern Brazil, inserted in two rock traditions: Nordeste and Agreste. Based on these similarities and using the cladistic analysis, it was possible to observe, in local terms, the evolution of the defined patterns, making possible the creation of hypotheses of their dispersion within the researched area. The results also provide support for confrontation of hypotheses about the dispersion of the Nordeste Tradition in that region, as already discussed by some authors.Keywords: Rock paintings; cladistic analysis; Cariri Ocidental
A (RE) CONSTRUÇÃO DA GEOMORFOLOGIA SEMIÁRIDA A PARTIR DO CONHECIMENTO TRADICIONAL: A Etnogeomorfologia Sertaneja
Authors: Ribeiro Simone Cardoso
Published: April 2017

O presente artigo objetiva discutir a geomorfologia semiárida nordestina a partir do conhecimento etnocientífico, visando compreender como os principais agentes modificadores do espaço do sertão entendem os processos geomórficos, como usam este conhecimento para o manejo do ambiente em que vivem e se, e como, utilizam estes saberes para algum tipo de taxonomia do relevo. Podemos concluir que os produtores rurais familiares do sertão tem vasto conhecimento sobre processos esculturadores do relevo, dominando um sistema próprio de estratificação dos ambientes – e das formas de relevo – com base em uma lógica que pode ser explicada, interpretada e articulada ao conhecimento gerado no meio científico. (RE) CONSTRUCTING SEMI-ARID GEOMORPHOLOGY FROM TRADITIONAL KNOWLEDGE: Brazilian Backlands Etnogeomorphology ABSTRACTThis article aims to discuss the northeastern semiarid geomorphology from the ethno scientific knowledge, aiming at understanding how the main modifying agents of the backwoods space understand the geomorphic processes, how they use this knowledge to manage the environment in which Live and if, and how, they use this knowledge for some type of relief taxonomy. We can conclude that the rural producers of the backwoods have vast knowledge about relief  culpturing processes, dominating their own system of stratification of environments - and relief forms - based on a logic that can be explained, interpreted and articulated to the knowledge generated in the scientific means.Keywords: landscape; ethno science; Cariri cearense

Authors: Tavares Bruno De Azevedo Cavalcanti , Galvão Diogo Cavalcanti
Published: April 2017

Usando como estudo de caso a Lagoa do Puiu em Ibimirim-PE, o presente trabalho compreende uma discussão sobre as possibilidades interpretativas dos resultados obtidos em pesquisas no semiárido do Nordeste do Brasil. Entre as variações climáticas durante a transição Pleistoceno/Holoceno e durante todo o Holoceno, foi identificado um episódio de máxima umidade no Holoceno Inferior. Embora a área de estudo se encontre atualmente em um ambiente semiárido e, portanto, com um déficit hídrico anual, a área da lagoa apresentou um nível da sua lâmina d’água cerca de 5 metros acima do nível atual. No entanto, buscando analisar esses resultados por meio das abordagens de conectividade, sensibilidade da paisagem e hidrogeomorfologia, foi possível interpretar os ajustes de deposição de forma distinta. De acordo com essa tentativa, os depósitos com estratificação plano-paralela foram interpretados como resultantes de uma obliteração de curto prazo em um meandro de um canal afluente da lagoa, uma vez que este sofreu agradação por sedimentos derivados das colinas adjacentes. DISCUSSING THE INTERPRETATIVE POSSIBILITIES OF THE PALEOCLIMATIC STUDIES: The Case of Puiu Lake, PE ABSTRACTUsing as case study the Puiu Lake at Ibimirim-PE, the present work comprehends a discussion of interpretative possibilities of the obtained results in researches at the semiarid in northeastern Brazil. Among climatic variations during the Pleistocene/Holocene transition and during the entire Holocene, was identified an humid maximum episode in the Lower Holocene. Although the study area lies currently within a semiarid environment and therefore with an annual hydric deficit, the lake area experienced past water stands as high as 5 meters above the current level. However, seeking to analyze those results by means of the connectivity, landscape sensitivity and hydrogeomorphology approaches, it was possible to interpret the deposition settings in a distinct manner. According to this attempt, deposits with plane parallel stratification were interpreted as resulting from a short term obliteration of a meander from a lake tributary channel, as it suffered aggradation by sediments derived from the adjacent hillslopes.Key-words: Palaeoenvironmental interpretation; Puiu Lake; Lacustrine deposits.

A highly-integrated experimental system for plasma decomposition of fuels was built. Experiments were conducted and confirmed that macromolecular chain hydrocarbons were cracked by large-gap dielectric barrier discharge under the excitation of a microsecond-pulse power supply. Alkanes and olefins with a C atom number smaller than 10 as well as hydrogen were found in the cracked products of n-decane (n-C10H22). The combination of preheating and plasma decomposition had strong selectivity for olefins. Under strong discharge conditions, micromolecular olefins were found in the products. Moreover, there was a general tendency that micromolecular olefins gradually accounted for higher percentage of products at higher temperature and discharge frequency.

Published: April 2017

Advanced driver assistance systems (ADAS) are technologies that provide drivers with essential information or take over difficult and repetitive tasks. They contribute to improving road safety and increasing driving comfort. Apart from the technical development challenges, training and demonstration of ADAS in safe environments are important concerns for automobile manufacturers and suppliers. This paper presents the concept and prototypical implementation of an innovative training station for learning ADAS with driving simulators. The training station has a scalable and modular architecture, so that more than one driving simulator can be connected to a common instructor unit. Fully immersive visualization is provided by utilizing head-mounted displays for the participating driving simulators. The instructor unit consists of a computer with a developed software tool for session control, monitoring, and evaluation. Moreover, the instructor can use a head-mounted display and participate within the same virtual environment of a selected trainee. A simulation model for an autonomous driving system was implemented and a group of test persons were involved to show the usability and validity of the developed training station for ADAS learning and demonstration.
Ecological Approaches to Quantifying (Bio)Diversity in Music
Authors: Angeler David G. , Benavent-Corai José
Published: April 2017

This paper introduces an ecological approach to quantifying diversity in musical compositions. The approach considers notations with distinct pitches and duration as equivalents of species in ecosystems, measures within a composition as equivalents of ecosystems, and the sum of measures (i.e., the entire composition) as a landscape in which ecosystems are embedded. Structural diversity can be calculated at the level of measures (“alpha diversity”) and the entire composition (“gamma diversity”). An additional metric can be derived that quantifies the structural differentiation between measures in a composition (“beta diversity”). We demonstrate the suitability of the approach in music using specifically composed examples and real songs that vary in complexity. We discuss the potential of the approach with selected examples from a potentially ample spectrum of applications within musicology research. The method seems particularly suitability for hypothesis testing to objectively identify many of the intricate phenomena in music. Because the approach extracts information present in the compositions – it lets the songs tell their structure – it can complement more complex modeling approaches used by music scholars. Combined such approaches provide opportunities for interdisciplinary research. They can help to fill knowledge gaps, stimulate further research and increase our understanding of music.

Published: April 2017

Process simulation represents an important tool for plant design and optimisation, either applied to well established or to newly developed processes. Suitable thermodynamic packages should be selected in order to properly describe the behaviour of reactors and unit operations and to precisely define phase equilibria. Moreover, a detailed and representative kinetic scheme should be available to predict correctly the dependence of the process on its main variables. This review points out some models and methods for kinetic analysis specifically applied to the simulation of catalytic processes, as a basis for process design and optimisation. Attention is paid also to microkinetic modelling and to the methods based on first principles, to elucidate mechanisms and calculate thermodynamic and kinetic parameters. Different case histories support the discussion. At first, we have selected two basic examples from the industrial chemistry practice, e.g. ammonia and methanol synthesis, which may be described through a relatively simple reaction pathway. Then, a more complex reaction network is deeply discussed to define the conversion of bioethanol into syngas/hydrogen or into building blocks, such as ethylene.
The Right to Remember: Implementing a Rudimentary Emotive-Effect Layer for Frustration on AI Agent Gameplay Strategy
Authors: Stallwood James , Ranchhod Ashok
Published: April 2017

AI is often looked at as a logical rational way to develop a games agent that methodically looks at options and delivers rational solutions. This paper is based on developing an AI agent that plays a game with a similar emotive content like a human. The purpose of the study was to see if the incorporation of this emotive content would influence the outcomes within the game Love Letter. In order to do this an AI agent with an emotive layer was developed to paly the game over a million times. A lower win/loss ratio demonstrates that to some extent this methodology was vindicated and a 100 per cent win for the AI agent did not happen. Machine learning techniques were modelled purposely so as to match extreme models of behavioural change. The results demonstrated a win/loss ration of 0.67 for the AI agent and in many ways reflectd the frustration that a normal player would exhibit during game play. As was hypothesised the final agent investment value was, on average, lower after matchplay than its initial value.
Polyethersulfone/Cellulose Acetate Butyrate Hybrid Hollow-Fiber Membranes for Organic-Matter Removal From Produced Water

Published: April 2017

In the US, for every barrel of oil, approximately 7 bbl of water is produced. Produced water consists of various amounts of organic and inorganic constituents from the source geologic formation and associated hydrocarbons. Produced-water handling has become a major effort for all waterflood operations. Membrane technology has been widely used for produced-water purification because of its economic and portable properties. However, the presence of organic matter in produced water causes serious membrane fouling, which shortens membrane life and increases operation costs. In this study, to reduce organic components in produced water, we fabricated a series of polyethersulfone (PES)/cellulose acetate butyrate (CAB) hybrid hollow-fiber membranes (HFMs) with different polymer-mass ratio for the removal of organic matter (benzene, toluene, octanoic acid, and hexanoic acid) from produced water. The morphology of the hybrid PES/CAB HFMs was characterized by scanning electron microscope (SEM) and atomic force microscope (AFM). The performance of the hybrid PES/CAB HFMs was evaluated in terms of permeate-water flux (PWF), organic-matter-removal efficiency, flux-decline ratio (FDR), and flux-recovery ratio (FRR). The results revealed that the PES/CAB hybrid HFMs comprised open-ended selective layers with homogeneous CAB distribution. Compared with neat PES HFM, the PES/CAB hybrid membranes exhibited 20.3% improvement of PWF. The organics-removal efficiency was higher than 99.8% for all the membranes. With 1.74 wt% of CAB in PES dope solution, the hybrid membranes possessed the lowest FDR and highest FRR, indicating the excellent antifouling ability of the PES/CAB HFMs. Because of these results, a two-stage antifouling HFM nanofiltration process was proposed as a follow-up work. The PES/CAB hybrid HFMs could serve as an attractive alternative for removing organic matter from produced water.
