The Sum and Its Parts: Judgmental Hierarchical Forecasting
Authors: Kremer Mirko , Siemsen Enno , Thomas Douglas J.
Published: December 2015

Firms require demand forecasts at different levels of aggregation to support a variety of resource allocation decisions. For example, a retailer needs store-level forecasts to manage inventory at the store, but also requires a regionally aggregated forecast for managing inventory at a distribution center. In generating an aggregate forecast, a firm can choose to make the forecast directly based on the aggregated data or indirectly by summing lower-level forecasts (i.e., bottom up). Our study investigates the relative performance of such hierarchical forecasting processes through a behavioral lens. We identify two judgment biases that affect the relative performance of direct and indirect forecasting approaches: a propensity for random judgment errors and a failure to benefit from the informational value that is embedded in the correlation structure between lower-level demands. Based on these biases, we characterize demand environments where one hierarchical process results in more accurate forecasts than the other.

Service Design for Improved Satisfaction: Decoding the Mechanism for Impact of Patient Callback in Emergency Healthcare
Authors: Krishnan Viswanathan , Maki Kanetaka M. , Castillo Edward M. , Guss David A.
Published: December 2015

Healthcare delivery is becoming a significant proportion of the service economy around the world. Within healthcare, the emergency department (ED) constitutes one of the most challenging areas of service delivery. Patient (customer) arrival is highly unpredictable, job scope is variable and uncertain, and timely service response is essential to save lives. In addition, emergency physicians and hospitals may soon be monitored and compensated based on patient satisfaction measured after service delivery. In this paper, we seek to understand how a process design piloted at two academic EDs—involving the addition of a new process step that uses health provider follow-up patient calls after discharge from the ED—influences patient assessment of the service. We examine the overall impact of this process redesign on patient satisfaction as measured by the “likelihood to recommend” question on patient surveys and develop an identification strategy to uncover the mechanism by which callbacks influence patient satisfaction. Our findings indicate that the follow-up callback design improves patient appraisals across the board, and not just as a service recovery tool where it moderates the assessment of select patient groups. These findings can help hospitals implement a redesign of the ED service process for callback in an effective manner. Underlying fundamental implications and future work possibilities are discussed.
Devolving public duties: can the social economy fulfil social rights?
Authors: Endo Chikako , Lim Sang Hun
Published: December 2015

This paper considers the implications for social rights when welfare provision is devolved from the state to the social economy. We bring together the idea of social rights as claims that entail institutionalised public duties, and that of the social economy as an institution for welfare provision based on voluntary, associational principles. After clarifying the tensions in rights provision within an associational framework, we argue that future research should consider how social economy organisations may shoulder collective duties independently, or how they could enhance social rights within the paradigm of the welfare state.
Midsummer of sex: Airing Emmanuelle on Finnish television
Authors: Saarenmaa Laura
Published: December 2015

Distributing sexual content has historically been more strictly regulated in Finland than in Denmark or Sweden. Airing Emmanuelle (1974), a French softcore erotic film by Jaeckin, on Finnish television in 1987 was shocking and front-page news. The article discusses the public reception of Emmanuelle in 1987 in the context of the commercialization of television in Finland.
Traversing the gender binary: Exploring ‘new’ Scandinavian trans cinema
Authors: Wallenberg Louise
Published: December 2015

In 2002, Norwegian film-maker Even Benestad’s documentary Alt om min far/All About My Father (2002), featuring Benestad together with his transvestite father, premiered at several film festivals. The film soon won several awards, and was nominated for many more. It can be classified as a foundational piece within a Scandinavian context: it blazed the way for other more genuine, more serious, representations of transgender issues on film. Investigating the trans cinema that has come out of Scandinavia in the aftermath of Benestad’s film, this article relates this cinema to the New Queer Cinema and to recent social changes regarding political, medical and legal discourses and possibilities for transgender individuals. The films discussed include Alt om min far/All About My Father (Benestad, 2002); En soap/A soap (Christensen, 2006); Ångrarna/Regretters (Lindeen, 2010); Pojktanten/She Male Snails (Bergsmark, 2012); Ta av mig/Undress me (Lindgren, 2013); and Nånting måste gå sönder/Something Must Break (Bergsmark, 2014).
A Look from the Inside: MicroCT Analysis of Burned Bones
Authors: Boschin Francesco , Zanolli Clément , Bernardini Federico , Princivalle Francesco , Tuniz Claudio
Published: December 2015

MicroCT imaging is increasingly used in paleoanthropological and zooarchaeological research to analyse the internal microstructure of bone, replacing comparatively invasive and destructive methods. Consequently the analytical potential of this relatively new 3D imaging technology can be enhanced by developing discipline specific protocols for archaeological analysis. Here we examine how the microstructure of mammal bone changes after burning and explore if X-ray computed microtomography (microCT) can be used to obtain reliable information from burned specimens. We subjected domestic pig, roe deer, and red fox bones to burning at different temperatures and for different periods using an oven and an open fire. We observed significant changes in the three-dimensional microstructure of trabecular bone, suggesting that biomechanical studies or other analyses (for instance, determination of age-at-death) can be compromised by burning. In addition, bone subjected to very high temperatures (600°C or more) became cracked, posing challenges for quantifying characteristics of bone microstructure. Specimens burned at 600°C or greater temperatures, exhibit a characteristic criss-cross cracking pattern concentrated in the cortical region of the epiphyses. This feature, which can be readily observed on the surface of whole bone, could help the identification of heavily burned specimens that are small fragments, where color and surface texture are altered by diagenesis or weathering.
Using Linked Open Data to Improve Data Reuse in Zooarchaeology
Authors: Kansa Sarah Whitcher
Published: December 2015

The inability of journals and books to accommodate data and to make it reusable has led to the gradual loss of vast amounts of information. The practice of disseminating selected sub-sets of data (usually in summary tables) permits only very limited types of reuse, and thus hampers scholarship. In recent years, largely in response to increasing government and institutional requirements for full data access, the scholarly community is giving data more attention, and solutions for data management are emerging. However, seeing data management primarily as a matter of compliance means that the research community faces continued data loss, as many datasets enter repositories without adequate description to enable their reuse. Furthermore, because many archaeologists do not yet have experience in data reuse, they lack understanding of what “good” data management means in terms of their own research practices. This paper discusses Linked Open Data (LOD) as an approach to improving data description, intelligibility and discoverability to facilitate reuse. I present examples of how annotating zooarchaeology datasets with LOD can facilitate data integration without forcing standardization. I conclude by recognizing that data sharing is not without its challenges. However, the research community’s careful attention and recognition of datasets as valuable scholarly outputs will go a long way toward ensuring that the products of our work are more widely useful.
A Museum Cruise in Foul Waters: An Empirical Analysis of the Debate Triggered by the Proposal to Move the Norwegian Viking Ships from Bygdøy to Bjørvika
Authors: Skrede Joar
Published: December 2015

This article analyzes the debate that ensued from a suggestion to relocate three Norwegian Viking ships from Bygdøy to Bjørvika. People do not only debate the ships’ material vulnerability but they also express different views of what a modern museum is and should be. Some want to upgrade and preserve the existing museum, while others want to relocate the ships and integrate them in a wider culture-led urban regeneration agenda. The ships are torn between local, regional, and national political interests, and people have different opinions about the histories in which they should be inscribed. The empirical corpus is primarily made up of newspaper articles from the last 20 years, and the different arguments are systemized and presented thematically. In the closing remark, the article suggests that the Viking Ship Museum would benefit from a more clearly defined long-term agenda.

Logicality of second-order logic: A critical inquiry on the related debates
İkinci seviye mantığın mantıksallığı: İlgili tartışmalar üzerine eleştirel bir değerlendirme
Authors: Öztürk Ali Bilge
Published: December 2015

Being the pioneer of modern logic, Frege, with his quantification theory, was the pioneer of not only first-order logic, but also second-order logic. But today, as it may be seen from the recent pedagogical works clearly, learning modern logic has become almost equivalent to learning first-order logic. In the other words, first-order logic appears as the most natural, paradigmatic and central system of logic. However second-order logic either doesn’t appear in recent pedagogical works or appears as an interesting detail of the history of logic. Moreover, today even the logicality of second-order logic has become controversial. In this controversy, two of the criticisms against the logicality of second-order logic have become more apparent than the others: (1) the logical incompleteness criticism, and (2) the ontological commitments criticism. In this study, these two criticisms, which was put forward as a justification of the claim that second order logic is not a purely-logical system, and several responses to these criticisms are tried to be clarified in a simple and untechnical manner. Additionally it is argued that, while these two criticisms are strong and justified, several responses to these criticisms are weak.

 

Özet

Modern mantığın öncüsü Frege niceleme kuramıyla, yalnızca birinci seviye mantığın değil, aynı zamanda ikinci seviye mantığın da öncüsüydü. Ancak günümüz pedagojik yapıtlarında da açıkça görülebileceği gibi bugün modern mantığı öğrenmek bunlardan birinci seviye mantığı öğrenmekle eşdeğer hale gelmiştir. Diğer bir deyişle birinci seviye mantık, mantığın en doğal, paradigmatik ve merkezi sistemi olarak kendini göstermektedir. Diğer taraftan ikinci seviye mantık ise günümüz pedagojik yapıtlarında ya yer almamakta ya da bu yapıtlarda mantık tarihinin ilginç bir ayrıntısı olarak yer almaktadır. Dahası bugün ikinci seviye mantığın mantıksallığı dahi tartışmalı hale gelmiştir. Bu tartışmalarda ikinci seviye mantığın mantıksallığına getirilen eleştirilerden ikisi diğerlerine göre daha belirgin hale gelmiştir. (1) Mantık sistemsel eksiklik eleştirisi ve (2) gizli ontolojik kabuller eleştirisi. Bu çalışmada ikinci seviye mantığın saf-mantıksal bir sistem olmadığı iddiasına gerekçe olarak ileri sürülen bu iki eleştiri ve bu eleştirilere getirilen çeşitli yanıtlar, basit ve teknik olmayan bir dille açık kılınmaya çalışılmıştır. Ek olarak bu iki eleştirinin güçlü ve haklı eleştiriler olduğu ve bu eleştirilere getirilen çeşitli yanıtların ise güçsüz olduğu savunulmuştur.
The Geographical Distribution Of The Black Locust (Robinia Pseudoacacia L.) In Poland And Its Role On Non-Forest Land
Authors: Wojda Tomasz , Klisz Marcin , Jastrzębowski Szymon , Mionskowski Marcin , Szyp-Borowska Iwona , Szczygieł Krystyna
Published: December 2015

The black locust (Robinia pseudoacaciaL.) has been present in Poland for more than 200 years now, its range coming to encompass the entire country, albeit with a particular concentration of occurrence in the west. Overall, it is present in 3.4% of the stands making up Poland’s “State Forests National Forest Holding” (Państwowe Gospodarstwo Leśne Lasy Państwowe), and is the dominant species in 0.1% of stands. Thanks to its producing durable wood of favourable energetic properties, this species is used in medium-rotation (≤ 40-year) plantations as well as in biomass energy plantations (where there is a 5–7-year rotation). In terms of its nectar production, the black locust is second only to lime as the Polish tree best serving the production of honey. While the species shows marked expansiveness in Poland, it has not thus far been placed on the list of aliens capable of threatening native species or natural habitats. Breeding of the species has been engaged in – if to only a limited extent – in Poland for some 20 years now, and 2 selected seed stands have been registered, as well as 34 plus trees and 2 seed orchards.
Investigation of sol-gel processed CuO/SiO2 nanocomposite as a potential photoanode material
Authors: Tenkyong Tenzin , Bachan Neena , Raja J. , Kumar P. Naveen , Shyla J. Merline
Published: December 2015

Synthesis and characterization of a highly efficient photoconductive nanocomposite comprising of two common metal oxides: copper oxide (CuO) and silicon dioxide (SiO2) are being reported in this paper. The CuO/SiO2 nanocomposite has been synthesized using a cost-effective and facile sol gel route. The structural, chemical and optical properties of the prepared samples have been studied using various characterization techniques. The UV-Vis analysis revealed better absorption in the case of the nanocomposite as compared to its parent materials. X-ray diffraction (XRD) analysis has been employed to determine the structural formation of the nanocomposite and the crystallite size with the use of Scherrer’s formula. The photo conductivity study of the sample showed enhanced photocurrent in the case of nanocomposite as compared to its single components, thus, presenting it as a potential candidate for solar cell applications, especially as photoanode material in the dye-sensitized solar cells (DSSC).
Avaliação da técnica de imunocromatografia para análise de drogas de abuso no contexto da química forense
Authors: Pinto G.A.T. , Freitas L.G. , Machado Y. , Marinho Pablo Alves
Published: December 2015

O uso abusivo de drogas é um problema de saúde pública mundial  que leva a graves consequências sociais e principalmente na saúde dos usuários. A prevalência da utilização de drogas pela população em geral vem aumentando consideravelmente. Deste modo, as análises químicas em drogas de abuso apresentam importância crucial para materialização do delito. A imunocromatografia é uma técnica de triagem, rápida, de fácil execução, dispensa o uso de reagentes adicionais, equipamentos e técnicos especializados, sendo bastante utilizada para a detecção de drogas em fluidos biológicos, mas carece de estudos para sua utilização em análises de drogas apreendidas. Sendo assim, o presente estudo aborda os aspectos analíticos da técnica de imunocromatografia, avaliando a eficiência desta técnica para a análise de drogas de abuso no contexto da química forense. Para o presente estudo as amostras sugestivas de maconha, cocaína e ecstasy (MDMA) apreendidas pela Polícia Civil de Minas Gerais foram analisadas por imunocromatografia e comparadas com outras técnicas como testes colorimétricos e análises instrumentais (FT-IR, GC-MS e LC-MS/MS). Parâmetros como taxas de falsos resultados, sensibilidade, seletividade e confiabilidade foram calculados utilizando tabelas de contingência. A imunocromatografia apresentou em média taxas de sensibilidade e seletividade de 94% e 75%, respectivamente. A menor confiabilidade constatada para análise de comprimidos de ecstasy deve-se principalmente ao grande número de resultados falso-positivos para MDMA, uma vez que essa técnica é pouco seletiva para essa substância, detectando diversas outras substâncias análogas. Portanto, a imunocromatografia se mostrou eficiente para a triagem de drogas apreendidas, uma vez que apresentou adequada sensibilidade e seletividade para drogas como maconha e cocaína e possibilidade de detectar outras drogas sintéticas além do ecstasy, as quais possivelmente não seriam detectadas pelos testes colorimétricos rotineiramente empregados pelos Peritos Criminais de campo.

Vestígios Psicológicos ou Comportamentais na Cena de Crime: uma Evidência Subutilizada no Arcabouço Pericial Brasileiro
Authors: Rosa Cássio Thyone Almeida
Published: December 2015

O presente artigo analisa um tipo particular de vestígio verificado nas cenas de crime: o vestígio psicológico ou comportamental, considerado como um vestígio muitas vezes negligenciado em inúmeros exames de locais de crime. Na introdução do artigo, uma classificação geral de vestígios é apresentada e dois conceitos são confrontados, o de vestígio material e o de vestígio imaterial. Na sequência, através de uma revisão que engloba diferentes abordagens a partir de consagrados autores, os vestígios são contextualizados e o vestígio comportamental é detalhado em relação a sua identificação, natureza e aplicações forenses. A importância desse tipo de vestígio é então demonstrada. Finalizando o artigo, são apresentados cinco casos nos quais os vestígios psicológicos podem ser identificados e discutidos, sendo três casos de homicídio e dois de suicídio. A conclusão do artigo reforça a necessidade de que peritos se prepararem para melhor explorar esse tipo de vestígio durante os exames de local de crime.

La revista Análisis, con el presente número dedicado a las formas de hacer historia, ha querido sumarse y contribuir de diversas maneras en un debate de mayor trascendencia académica, que no sólo le concierne al campo de la historia o de las ciencias humanas, sino también a todas las ciencias exactas. Este debate, común en todas las ramas del conocimiento humano, consiste en preguntarnos a la hora de formular un problema de investigación: ¿sobre qué tema es necesario indagar o escribir? y ¿desde cuál(es) perspectiva(s) teórica(s) o metodológica(s) es mejor hacerlo? Ambas preguntas casi siempre se intentan resolver, por un lado, recurriendo a los postulados de aquellos autores considerados como “fundacionales”
en una determinada ciencia o conocimiento y, por el otro, acogiendo los temas de mayor incidencia o trascendencia en el ámbito académico.
La tradición colonial y la pintura del siglo XIX en Colombia
Authors: Gómez Jaime Humberto Borja
Published: December 2015

El presente artículo pretende mostrar, desde la práctica de la pintura,
cómo la primera mitad del siglo XIX se comporta como una articulación entre la cultura colonial del siglo XVIII y el tránsito hacia las nuevas propuestas academicistas y costumbristas que se pusieron de moda a partir de la segunda mitad del siglo XIX. Y cómo, sin embargo, buena parte del mismo continuó anclado en la tradición colonial, tanto en los contenidos como en las formas.
Freges Unterscheidung Von Sinn Und Bedeutung
Authors: Spohn Wolfgang
Published: December 2015

Das Ziel dieser Vorlesung ist es, eine Einführung in die Sprachphilosophie zu geben. Dies soll anhand der folgenden Frage geschehen: Was ist die Bedeutung von Namen? Ich habe also nicht vor, sämtliche Gebiete der Sprachphilosophie zu behandeln, sondern will Ihnen vielmehr grundlegende Kenntnisse in dieser Disziplin vermitteln, besonders in der Freges Unterscheidung von Sinn und Bedeutung. Die Motivation für dieses Vorgehen ist diese: Gerade am Beispiel der Theorie der Namen lassen sich wesentliche Probleme und Leitfragen der Sprachphilosophie sehr gut aufrollen. Daher bietet sich eine Konzentration auf diese Thematik im Rahmen
einer Veranstaltung mit einführendem Charakter geradezu an. Im übrigen gibt es wenig an systematischen einführenden Auseinandersetzungen mit der Entwicklung der Namenstheorie von den Anfängen der modernen Sprachphilosophie bis hm zu den neueren und neuesten Ansätzen.
Debate sobre la indeterminación de la traducción lingüística propuesta por W.V. Quine
Authors: Lukomski Andrzej
Published: December 2015

El presente artículo pretende invitar a una discusión frente a la propuesta de Quine, quien plantea la hipótesis de la indeterminación de la traducción lingüística. El debate que se libró alrededor de esta hipótesis quisiera trasladarlo al campo de las ciencias naturales con el fin de buscar la fundamentación de un nuevo sistema de racionalidad, que permite superar el modelo positivista de las ciencias naturales, el cual, con sus suposiciones reduccionistas, obstaculiza el trabajo interdisciplinar que
se propone en los tiempos de globalización. En la propuesta quiniana, a mi modo de ver, podemos encontrar valiosos elementos teóricos que abren las posibilidades a nuevos paradigmas de la ciencia.
Las profecías científico-políticas de Bertrand Russell
Authors: Soto Damián Pachón
Published: December 2015

En este artículo se realiza un análisis del libro Ícaro o el futuro de la ciencia publicado por Bertrand Russell en 1924. En el presente ensayo estudio
detalladamente el contexto histórico (el desencantamiento del mundo y los inicios del siglo XX) e intelectual en que el filósofo inglés expone sus reflexiones en torno a los peligros que la ciencia entraña para la humanidad, así como de las posibles consecuencias políticas de las intervenciones genéticas. Muestro, igualmente, las afinidades que Russell tuvo en la época con pensadores críticos de la civilización, como Max Weber, Lukács, Simmel, entre otros. En este sentido, las reflexiones expuestas por Russell hace más de ochenta años son actuales y pueden considerarse como verdaderamente proféticas, pues atisban hechos que aún no han
sucedido pero que con la actual revolución en la ingeniería genética pueden llegar a ser un hecho.
La pedagogía como espacio posible de convergencia de las humanidades y la ingeniería
Authors: Aparicio Patricia Reyes
Published: December 2015

Más que afirmaciones, el presente texto se pregunta por la eventualidad de hacer converger, en el campo abierto por la pedagogía, el discurso de las humanidades y el de las ingenierías: ¿es acaso esto posible? ¿Qué condiciones habría que crear para que esa convergencia reportara beneficios en la perspectiva del pensamiento, de la investigación? Mostrar, enseñar, exponer-se: posibilidades que quedan abiertas cuando de pensar de pedagogía se trata. De modo que, antes que fronteras disciplinares, horizontes de riesgo, planos abiertos de emergencia a impensables modos del ser y de sus relaciones, porque incluso en estos campos los desarrollos de las subjetividades son posibles, y con ellos, las transformaciones del mismo pensamiento disciplinar sobre el que se ha erigido el mundo, hecho que
admite y hasta reclama transformaciones.
Lo simbólico y lo imaginario a propósito del hombre. Supuestos para una reflexión sobre la mujer
Authors: Sánchez Ildefonso
Published: December 2015

Con el presente artículo, se pretende contribuir al esclarecimiento de la discusión que se desarrolla actualmente en torno a la pregunta por el hombre. En esta discusión, se rechaza la posición radical acerca de la muerte del hombre, fundada
en la apreciación foucaultiana de la historia, y de la muerte de la representación
en el futuro, para inscribirse, por el contrario, en el horizonte que reclama, como lo hace Sloterdijk, la necesidad de pensar una nueva antropología. Esta posición se firma más en las argumentaciones sostenidas por Lacan y Zizek, articuladas, por supuesto, en una dinámica diferente a la de la Escuela Crítica y a la de un nihilismo escéptico. Por eso la importancia de recuperar, entre otros, el concepto de universal concreto, de conformidad con la indicación de Zizek de leer a Lacan desde Hegel y viceversa. Se profundiza así el sentido de la historia y la construcción de una subjetividad libre.

TIC y mediaciones culturales en la educación superior: hacia un programa multidimensional
Authors: Franco Didier Santiago , López Juan Sebastián López
Published: December 2015

Tras una primera etapa de reflxión sobre la relación TIC-educación centrada en la brecha digital, se viene reconociendo la necesidad de estudiar, además, la cuestión de la capacitación necesaria para sacar provecho a los recursos tecnológicos disponibles. Sin embargo, se sigue prestando poca atención a la dimensión simbólica de la tecnología en general y de las TIC en particular, lo que genera serias dudas acerca del papel real que juega la cultura tanto en el discurso de la cultura digital como en el debate sobre la educación en la sociedad del conocimiento. En este sentido, el paso de la cultura como categoría residual a variable independiente surge de reconocer que: (a) las personas no sólo usan las tecnologías, sino que, sobre todo, las personalizan, las dotan de sentido y las hacen parte integral de su experiencia de mundo, y que (b) dichos procesos emergen no solo de experiencias subjetivas con las TIC, sino de robustas narrativas culturales en torno a las tecnologías. Este giro epistemológico hace posible un análisis multidimensional de las TIC en la educación, en el que la convergencia entre las dimensiones funcional y
sociocultural de la tecnología arrojaría luces sobre la contradicción que muchos críticos de las nuevas tecnologías han puesto de manifisto: la alta disponibilidad de recursos tecnológicos no garantiza mejores resultados en el plano cognitivo ni un enriquecimiento de nuestro capital cultural como sociedad. De ahí que la introducción de un programa cultural, ambicioso y dinámico, sea decisivo en el futuro de la investigación sobre educación superior y TIC.
El (des)orden de las ciudades
Authors: Maldonado Carlos Eduardo
Published: December 2015

Las ciudades son sistemas físicos, y estos tienen un orden. En la física clásica –esto es, en la mecánica clásica–, el orden era estable, rígido, jerárquico o regular y periódico. Los principios que explican dicho orden son, en verdad, elementales. Sin embargo, con la nueva física, dicho orden se revela como de mayor complejidad. Asimismo, las ciudades son sistemas vivos exactamente en la medida en que metabolizan información, materia y energía. Ahora bien, la complejidad del mundo actual está relacionada profundamente con la digitalización del mismo. Ello implica nuevos modos de escritura, nuevos modos de lectura, nuevos modos de comunicación y, manifiestamente, nuevos lenguajes. De allí que se advierta la emergencia de una nueva clase social: la de los migrantes y los nativos en las tecnologías convergentes. Son ellos los que están redefiiendo el (des)orden de las ciudades. Pues no sin ambages, la ciudad es ahora y cada vez más, el lugar de la comunicación y el lenguaje, de las vivencias y el convivio. Y para escándalo de las mentalidades tradicionales, el convivio y el habitar, la comunicación y el lenguaje son cada vez más digitales. Una auténtica revolución, en toda la línea de la palabra.
Avatar-habitar-actuar. Jóvenes en las redes sociales virtuales: ¿habitantes, navegantes o actores digitales?
Authors: Gil Mónica Eliana García , Serna Edwin Arcesio Gómez
Published: December 2015

Este artículo tiene como eje central la pregunta por cómo la acción colectiva y las prácticas políticas de grupos de jóvenes con presencia en la red social Facebook, pueden considerarse formas de habitar y configurar escenarios virtuales, al tiempo que contribuyen a la construcción y actuación de los jóvenes como sujetos políticos. Busca un acercamiento a la relación entre prácticas de participación políticay formas de habitar, crear identidades (políticas, principalmente), y establecer relaciones en escenarios virtuales,en el marco de las particularidades que imponen el ciberespacio y la cibercultura. Desde esta relación se establece un vínculo con los procesos de construcción de lo público y el ejercicio de la ciudadanía, soportado en categorías tanto de la comunicación como de la política, a saber: mediación(Debray; Torrico; Martín-Barbero); participación política, prácticas de participación política(Alvarado; Vommaro; Aguilera; Botero y Torres; Balardini;Pisani y Piotet; Rueda; Saintout); cultura política (López de la Roche), lo público, la ciudadanía; y los jóvenes como sujetos políticos. Se incorporan también las categorías habitar(Michel de Certeau), Ciberespacio y cibercultura (Castells; Pierre Lévy; Rocío Rueda) y la construcción de identidades (individuales y colectivas)en el ciberespacio (Turkle; Piscitelli; Castells; Finquelievich). Esta investigación tiene un enfoque cualitativo y sustenta sus instrumentos y estrategias de recolección de información en postulados etnográficos, con énfasis en la etnografía virtual. El análisis de la información es de tipo hermenéutico, a partir del seguimiento a grupos, páginas y perfiles creados en Facebook, junto con entrevistas a alguno de los sujetos de la investigación.
Las emociones en el desarrollo del juicio moral, en perspectiva de educación filosófica
Authors: Bedoya Gallego Nelson Iván , Rey Vásquez Elías Manaced , Romero Neisa William Harold
Published: December 2015

Como resultado de una investigación aplicada, el presente artículo ofrece un análisis crítico sobre el lugar de las emociones en el campo educativo. Basados en la clasificación de Cheshire Calhoum y Robert Solomon (1992), se opta por la propuesta evaluativa y cognitiva en la que se inscribe a la profesora Martha Nussbaum, donde las emociones son consideradas como juicios que, en tanto se basan en creencias y orientan a la acción, cumplen un papel esencial en nuestras decisiones. En ese orden de ideas, el documento analiza la propuesta teórica de la emoción como juicio y su importancia en la comprensión de la formación del juicio moral, además del papel de la educación de las emociones en contraste con el intelectualismo moral y desde una perspectiva de educación filosófica. Finalmente se propone que la imaginación, la argumentación y la deliberación en el marco de lo moral, son las dimensiones humanas que se favorecen y privilegian en una educación de las emociones.
Targeting of P-Element Reporters to Heterochromatic Domains by Transposable Element 1360 in Drosophila melanogaster

Published: December 2015

Heterochromatin is a common DNA packaging form employed by eukaryotes to constitutively silence transposable elements. Determining which sequences to package as heterochromatin is vital for an organism. Here, we use Drosophila melanogaster to study heterochromatin formation, exploiting position-effect variegation, a process whereby a transgene is silenced stochastically if inserted in proximity to heterochromatin, leading to a variegating phenotype. Previous studies identified the transposable element 1360 as a target for heterochromatin formation. We use transgene reporters with either one or four copies of 1360 to determine if increasing local repeat density can alter the fraction of the genome supporting heterochromatin formation. We find that including 1360 in the reporter increases the frequency with which variegating phenotypes are observed. This increase is due to a greater recovery of insertions at the telomere-associated sequences (∼50% of variegating inserts). In contrast to variegating insertions elsewhere, the phenotype of telomere-associated sequence insertions is largely independent of the presence of 1360 in the reporter. We find that variegating and fully expressed transgenes are located in different types of chromatin and that variegating reporters in the telomere-associated sequences differ from those in pericentric heterochromatin. Indeed, chromatin marks at the transgene insertion site can be used to predict the eye phenotype. Our analysis reveals that increasing the local repeat density (via the transgene reporter) does not enlarge the fraction of the genome supporting heterochromatin formation. Rather, additional copies of 1360 appear to target the reporter to the telomere-associated sequences with greater efficiency, thus leading to an increased recovery of variegating insertions.
A Delicate Balance Between Repair and Replication Factors Regulates Recombination Between Divergent DNA Sequences inSaccharomyces cerevisiae
Authors: Chakraborty Ujani , George Carolyn M , Lyndaker Amy M , Alani Eric
Published: December 2015

Single-strand annealing (SSA) is an important homologous recombination mechanism that repairs DNA double strand breaks (DSBs) occurring between closely spaced repeat sequences. During SSA, the DSB is acted upon by exonucleases to reveal complementary sequences that anneal and are then repaired through tail clipping, DNA synthesis, and ligation steps. In baker’s yeast, the Msh DNA mismatch recognition complex and the Sgs1 helicase act to suppress SSA between divergent sequences by binding to mismatches present in heteroduplex DNA intermediates and triggering a DNA unwinding mechanism known as heteroduplex rejection. Using baker’s yeast as a model, we have identified new factors and regulatory steps in heteroduplex rejection during SSA. First we showed that Top3-Rmi1, a topoisomerase complex that interacts with Sgs1, is required for heteroduplex rejection. Second, we found that the replication processivity clamp proliferating cell nuclear antigen (PCNA) is dispensable for heteroduplex rejection, but is important for repairing mismatches formed during SSA. Third, we showed that modest overexpression of Msh6 results in a significant increase in heteroduplex rejection; this increase is due to a compromise in Msh2-Msh3 function required for the clipping of 3′ tails. Thus 3′ tail clipping during SSA is a critical regulatory step in the repair vs. rejection decision; rejection is favored before the 3′ tails are clipped. Unexpectedly, Msh6 overexpression, through interactions with PCNA, disrupted heteroduplex rejection between divergent sequences in another recombination substrate. These observations illustrate the delicate balance that exists between repair and replication factors to optimize genome stability.
Apostolepis christineae Lema, 2002 (Serpentes: Xenodontinae: Elapomorphini): first record for Bolivia
Authors: Entiauspe-Neto Omar Machado , Lema Thales De
Published: December 2015

The fossorial snake Apostolepis christineae is an Elapomorphini species known only from a single specimen in Brazil. In this study, we report its occurrence to Bolivia, based on a male (BMNH 1907.10.31.62) from Puerto Suarez, Provincia German Busch, Departamento Santa Cruz, which was previously misidentified as Apostolepis vittata. This record extends the species distribution ca. 576 km west from its type locality. We also provide data on its morphological variation.
Tracing the lines of an electronic tattoo
Authors: Vitos Botond
Published: December 2015

Based on ethnographic fieldwork conducted in Melbourne, this article investigates the local techno scene and attempts to establish techno-cultural connections with its roots in Detroit. From a theoretical perspective based on the work of Jean Baudrillard and Kodwo Eshun, three aspects of techno parties are explored, each shaped by the intertwined factors of music, drug and environment. The first discussion considers the hidden and ephemeral fluctuation of the dance floor vibe within the context of an underground scene, which is juxtaposed with the ‘undetectible’ (Eshun 1998: 120) transmissions of early Detroit techno. The two remaining analyses assess the covert operation of techno through the analogy of electronic tattooing, applied first on the human and then on the urban body. The pulsating tattoo lines emerge from technological appropriations that dismantle and reconfigure urban reality, developing the complexities of the Baudrillardian virtual.

This article explores the role of free editorial coverage of local contemporary music in localized print media. The discussion here centres on activity which occurs in Perth, Western Australia, with a particular focus on the coverage of indie pop/rock music in three publications. The analysis presented here draws upon semi structured research interviews undertaken with editors of Drum Media Perth, X-Press Magazine and The West Australian. As this article argues, local print music media plays a key role in the promotion of local music activity as a cohesive ‘scene’ and industry to local audiences while also making a contribution to broader national music and media culture. In turn, this article also briefly comments upon recent debates about the climate of music journalism in Australia, as well as developments in this sector, such as the uptake of digital outlets.
Mutiny Music
Authors: Cummins Joseph
Published: December 2015

Mutiny Music is a twelve-part jazz suite composed by Rick Robertson in 2006 and performed by his band Baecastuff, a Sydney-based contemporary jazz ensemble. The work retells the mythic story at the foundations of two Pacific island communities, Pitcairn and Norfolk. This article will locate Mutiny Music within the shared discourses of the island and the archipelago. The discussion will open a number of lines historical and conceptual inquiry into the narrative operation of the work and its use of various musical forms. Of particular concern is the use of speech sampling and how such a practice inscribes the complex spatiotemporality of the island and archipelago while mapping the relation between Pitcairn and Norfolk in sound.

In this Riff article, Samuel Whiting speaks to live music advocate and Melbourne music industry professional Rebekah Duke. The interview focuses on the small live music venues of Melbourne’s inner-northern suburbs and the social scenes that inhabit them, exploring the role that these spaces play within the city’s broader live music scene in Australia’s cultural capital. The significance of these venues is reflected within Duke’s first-hand experiences, emphasizing ideas of vernacular cultural history and place-making.
Towards Open Agent Systems Through Dynamic Incorporation

Published: December 2015

This work tackles the problem of providing a mechanism and infrastructure for allowing a given Multiagent System (MAS) to become open, allowing the incorporation of newly incoming agents to participate within the existing society. For this, a conceptual analysis of the so-called conciliation problem is presented, covering the diverse levels and issues involved in such a process. Our Dynamic Incorporation Architecture is presented, which implements an infrastructure for allowing the participation of external agents into a specific multiagent system by incorporating the appropriate behaviours upon arrival. Our multiagent architecture for dynamic incorporation covers three levels: semantics, communication and interaction and has been applyed in a book-trading e-market scenario.
Meta-Rationality in Normal Form Games

Published: December 2015

A new generative relation for Nash equilibrium is proposed. Different types of equilibria are considered in order to incorporate players different rationality types for finite non cooperative generalized games with perfect information. Proposed equilibria are characterized by use of several generative relations with respect to players rationality. An evolutionary technique for detecting approximations for equilibria is used. Numerical experiments show the potential of the method.

ABSTRACT Objective To contribute our experience with surgical treatment of patients with mesial temporal lobe epilepsy (mTLE) undergoing anterior temporal lobectomy (ATL) or selective amygdalohippocampectomy (SelAH). Method This is a retrospective observational study. The sample included patients with medically refractory mTLE due to unilateral mesial temporal sclerosis who underwent either ATL or SelAH, at Hospital de Clinicas – UFPR, from 2005 to 2012. We report seizure outcomes, using Engel classification, cognitive outcomes, using measurements of verbal and visuospatial memories, as well as operative complications. Result Sixty-seven patients (33 ATL, 34 SelAH) were studied; median follow-up was 64 months. There was no statistically significant difference in seizure or neuropsychological outcomes, although verbal memory was more negatively affected in ATL operations on patients’ dominant hemispheres. Higher number of major complications was observed in the ATL group (p = 0.004). Conclusion Seizure and neuropsychological outcomes did not differ. ATL appeared to be associated with higher risk of complications.

ABSTRACT Pompe disease (PD) is a potentially lethal illness involving irreversible muscle damage resulting from glycogen storage in muscle fiber and activation of autophagic pathways. A promising therapeutic perspective for PD is enzyme replacement therapy (ERT) with the human recombinant enzyme acid alpha-glucosidase (Myozyme®). The need to organize a diagnostic flowchart, systematize clinical follow-up, and establish new therapeutic recommendations has become vital, as ERT ensures greater patient longevity. A task force of experienced clinicians outlined a protocol for diagnosis, monitoring, treatment, genetic counseling, and rehabilitation for PD patients. The study was conducted under the coordination of REBREPOM, the Brazilian Network for Studies of PD. The meeting of these experts took place in October 2013, at L’Hotel Port Bay in São Paulo, Brazil. In August 2014, the text was reassessed and updated. Given the rarity of PD and limited high-impact publications, experts submitted their views.
Institutional Integrated Teletandem: What have we been learning about writing and peer feedback?
Authors: ARANHA Solange , CAVALARI Suzi Marques Spatti
Published: December 2015

ABSTRACT We define institutionally integrated teletandem (iiTTD) as a series of teletandem sessions that are embedded in regular foreign language lessons, so that such lessons both feed and are fed by teletandem practice. In this paper, we analyze prospective Brazilian teachers correcting American students' writing productions in Portuguese during their participation in an iiTTD. We address issues about how pre-service FL teachers (participants in iiTTD) offer writing feedback to their peers. Data included all the texts written and revised during the length of their partnership. Results show that most participants tend to correct their iiTTD partners' written productions in a direct way, focusing mainly on language form and according to their beliefs and experience as learners.
Teletandem as a complex learning environment: Looking for a model
Authors: MOMPEAN Annick Rivens , CAPPELLINI Marco
Published: December 2015

ABSTRACT This article presents a model of teletandem, i.e. tandem through desktop videoconferencing (Telles 2009). The aim of such a model is twofold: heuristic and pedagogical. It is heuristic because it enables us to understand teletandem at all its levels and partially to predict (in probabilistic terms) what can happen in a teletandem environment. It is also pedagogical because it helps us formulate plans of action to improve future use and environment design. To build this model, we have drawn upon complexity theory (Larsen-Freeman & Cameron 2008, Morin 1990), which leads us to distinguish different levels of analysis before discussing the relationship between the different elements and levels leading to the complex final (yet dynamic) model.
Teletandem within the Context of closely-related languages: a Portuguese-Spanish interinstitutional experience
Authors: CARVALHO Kelly Cristiane Henschel Pobbe de , MESSIAS Rozana Aparecida Lopes , DÍAS Anelly Mendoza
Published: December 2015

ABSTRACT This paper is part of an ongoing research project aimed at observing the ways that Brazilian undergraduate students who are majoring in Portuguese and Spanish as part of a Foreign Languages and Literatures (FLL) degree program organize and implement the teaching of Portuguese for Spanish speakers within a teletandem context. We sought to evaluate the organization of the content of Portuguese language that they are teaching and the impact made by teletandem practices on the professional development of these student-teachers in both languages. Methodologically, the study is grounded on critical qualitative research. Data analysis suggests that, because Portuguese an d Spanish are closely related languages with a high level of inter-comprehension, the virtual learning context of teletandem requires the presence of a teacher-mediator to conduct the mediation sessions with focused attention to contrasting linguistic and cultural aspects between both languages.
