Bowing to the Dharma: Japanese Buddhist Women Leaders & Healers
Authors: Arai Paula
Published: November 2017

The prodigious stream of Japanese Buddhist women in roles of leadership and healing extends the length of Japanese Buddhist history. This article will highlight the transformative power of bowing that helped galvanize Sōtō Zen nuns on the eve of the twentieth century and feature twentieth-century leaders who institutionalized their disciplined commitments. It will also offer a window into the creative healing practices that characterizes women’s activity in the home.
Use of High-Quality and Common Commercial Mirrors for Scanning Close-Range Surfaces Using 3D Laser Scanners: A Laboratory Experiment
Authors: Riquelme Adrián , Ferrer Belén , Mas David
Published: November 2017

Three Dimension (3D) laser scanners enable the acquisition of millions of points of a visible object. Terrestrial laser scanners (TLS) are ground-based scanners, and nowadays the available instruments have the ability of rotating their sensor in two axes, capturing almost any point. Since many sensors can only operate in a vertical position, they cannot capture points located beneath themselves. Consequently, these instruments are generally unable to capture data in a vertical descending direction. Moreover, since the device positioning has certain requirements of space and terrain stability, it is possible that specific regions of interest are outside the reach of the laser. A possible solution is to address the laser beam towards the desired direction by means of a mirror. Common mirrors are very cheap; therefore, they are easy to manipulate and to substitute in case they get broken. However, due to their careless fabrication process, it seems reasonable to think that they are unprecise. In contrast, front-end mirrors are more expensive and delicate, and consequently, deflecting angles are more precise. In this research, we designed a laboratory test to analyze the arising noise when standard and high-quality mirrors are used during the TLS scanning process. The results show that the noise introduced when scanning through a standard mirror is higher than that produced when using a high-quality mirror. However, both cases show that this introduced error is lower than the instrumental error. As a result, this study concludes that it is reasonable to use standard mirrors when scanning in similar conditions to this laboratory test.
Carbon-Based Nanomaterials in Biomass-Based Fuel-Fed Fuel Cells

Published: November 2017

Environmental and sustainable economical concerns are generating a growing interest in biofuels predominantly produced from biomass. It would be ideal if an energy conversion device could directly extract energy from a sustainable energy resource such as biomass. Unfortunately, up to now, such a direct conversion device produces insufficient power to meet the demand of practical applications. To realize the future of biofuel-fed fuel cells as a green energy conversion device, efforts have been devoted to the development of carbon-based nanomaterials with tunable electronic and surface characteristics to act as efficient metal-free electrocatalysts and/or as supporting matrix for metal-based electrocatalysts. We present here a mini review on the recent advances in carbon-based catalysts for each type of biofuel-fed/biofuel cells that directly/indirectly extract energy from biomass resources, and discuss the challenges and perspectives in this developing field.
Full-Body Locomotion Reconstruction of Virtual Characters Using a Single Inertial Measurement Unit
Authors: Mousas Christos
Published: November 2017

This paper presents a method of reconstructing full-body locomotion sequences for virtual characters in real-time, using data from a single inertial measurement unit (IMU). This process can be characterized by its difficulty because of the need to reconstruct a high number of degrees of freedom (DOFs) from a very low number of DOFs. To solve such a complex problem, the presented method is divided into several steps. The user’s full-body locomotion and the IMU’s data are recorded simultaneously. Then, the data is preprocessed in such a way that would be handled more efficiently. By developing a hierarchical multivariate hidden Markov model with reactive interpolation functionality the system learns the structure of the motion sequences. Specifically, the phases of the locomotion sequence are assigned in the higher hierarchical level, and the frame structure of the motion sequences are assigned at the lower hierarchical level. During the runtime of the method, the forward algorithm is used for reconstructing the full-body motion of a virtual character. Firstly, the method predicts the phase where the input motion belongs (higher hierarchical level). Secondly, the method predicts the closest trajectories and their progression and interpolates the most probable of them to reconstruct the virtual character’s full-body motion (lower hierarchical level). Evaluating the proposed method shows that it works on reasonable framerates and minimizes the reconstruction errors compared with previous approaches.
Botulinum Toxin in Management of Limb Tremor
Authors: Zakin Elina , Simpson David
Published: November 2017

Essential tremor is characterized by persistent, usually bilateral and symmetric, postural or kinetic activation of agonist and antagonist muscles involving either the distal or proximal upper extremity. Quality of life is often affected and one’s ability to perform daily tasks becomes impaired. Oral therapies, including propranolol and primidone, can be effective in the management of essential tremor, although adverse effects can limit their use and about 50% of individuals lack response to oral pharmacotherapy. Locally administered botulinum toxin injection has become increasingly useful in the management of essential tremor. Targeting of select muscles with botulinum toxin is an area of active research, and muscle selection has important implications for toxin dosing and functional outcomes. The use of anatomical landmarks with palpation, EMG guidance, electrical stimulation, and ultrasound has been studied as a technique for muscle localization in toxin injection. Earlier studies implemented a standard protocol for the injection of (predominantly) wrist flexors and extensors using palpation and EMG guidance. Targeting of muscles by selection of specific activators of tremor (tailored to each patient) using kinematic analysis might allow for improvement in efficacy, including functional outcomes. It is this individualized muscle selection and toxin dosing (requiring injection within various sites of a single muscle) that has allowed for success in the management of tremors.
Efficient Use of Water Resources in the Steel Industry

Published: November 2017

In the steel sector water management aims at improving the sustainability of the production cycle, resulting in resource efficiency benefits and in reduced water demand and costs. To be reused, water needs to be cooled and desalinized to avoid salt concentration in water circulation systems. The presented work includes two case studies carried out in an integrated steelmaking plant, respectively, to evaluate the possible implementation of ultrafiltration and reverse osmosis to reduce salt concentration in water streams and to investigate, through modelling and simulation, a process integration solution to improve water efficiency. Results showed that most salts are removed by reverse osmosis and that its coupling with ultrafiltration allows obtaining very high quality water; reuse of desalinated wastewater resulted in being more suitable and economically viable than its discharge. Moreover, modelling and simulation showed that the considered blowdown could be reused without significant changes in the receiving water network area. The industrial implementation of water recovery solutions can lead to a decrease of fresh water consumption, effluent discharge, and to improvement of product quality and equipment service life. The considered desalination technologies are transferable and easily implementable, and modelling and simulation are very useful in order to evaluate process modifications before real implementation.
Older Tourists, Bars, and Instant Conviviality in Pub Street, Siem Reap, Cambodia
Authors: Bell Claudia
Published: November 2017

This an investigation of older tourists and street life. The purpose is to include this group in accounts of tourist practices, and to invite recognition of the value of such places to this demographic. Distinct tourist zones in popular tourist cities attract patrons of all ages and
nationalities. Streets of cafés, bars, and restaurants provide a warm welcome, "local color," sustenance, relaxation, and companionship. Pub Street, Siem Reap, Cambodia is one such street. The region is home of the famous Angkor Watt temple complex. After sightseeing, here people relax,
eager for conversation with anyone happy to sit and chat. Many are retirees or elderly visitors, welcome as consumers in this entertainment precinct. This article extends my exploration of Western retirees in Southeast Asia. A key aim is to note the significance to older tourists of a particular
visitor space. In a street they perceived as safe and welcoming they happily defy the stereotypical expectations of their behavior as "old people" back home. But what was the practicable and ethical way to collect material from the visitors as they socialized? It was quickly found that participants
were readily accessed. Mobile subjects need mobile methods; immersion in the activities of the subjects under study dissolved the barriers between researcher and participant. An approach for a formal interview later would not work, as many departed from Seim Reap early the next day. Ephemeral
events and behaviors could only be captured in this way, even though it challenged institutionalized protocols about what appropriately constitutes research. This article contributes a new strand to spatial studies, locating older tourist as enthusiastic patrons of entertainment precincts.
The scope of this project has been limited to just the small precinct of Seim Reap.
Communication Skills in the Tourism Sector: The Speech Culture of Tour Guides
Authors: Topler Jasna Potočnik
Published: November 2017

This article examines the study of the speech culture of 103 Slovene tour guides employing tourism discourse in their mother tongue by using participant observation, active listening, and linguistic analysis. Besides the knowledge of foreign languages, for tourism guides the mother
language skills in the current study of the Slovene language play a significant role. However, it turned out that also, in the education of tour guides, this area is not regulated systematically and is not a part of tour guides' education modules in Slovenia, but left to the individual's life-long
learning process or to the acquired level of knowledge during formal schooling in secondary or grammar schools. Consequently, tour guides are not yet trained systematically in speech culture. It should be observed that in the analyzed speech situations the usage of dialects, which can contribute
to the quality of the tourist experience in some speech situations, was not appropriate. The guides' language during their presentations and guidance had stronger or weaker traces of dialects and they also often made some typical pronunciation mistakes, such as pronouncing the incorrect syllable,
the incorrect pronunciation of the l-participles, or the incorrect pronunciation of some proper name also in speech situations that required the use of standard language instead of dialects. All this can result in the negative tourist experience, especially when tourists are more demanding.
Electron beam induced deposition of silacyclohexane and dichlorosilacyclohexane: the role of dissociative ionization and dissociative electron attachment in the deposition process
Authors: P Ragesh Kumar T , Hari Sangeetha , Damodaran Krishna K , Ingólfsson Oddur , Hagen Cornelis W
Published: November 2017

We present first experiments on electron beam induced deposition of silacyclohexane (SCH) and dichlorosilacyclohexane (DCSCH) under a focused high-energy electron beam (FEBID). We compare the deposition dynamics observed when growing pillars of high aspect ratio from these compounds and we compare the proximity effect observed for these compounds. The two precursors show similar behaviour with regards to fragmentation through dissociative ionization in the gas phase under single-collision conditions. However, while DCSCH shows appreciable cross sections with regards to dissociative electron attachment, SCH is inert with respect to this process. We discuss our deposition experiments in context of the efficiency of these different electron-induced fragmentation processes. With regards to the deposition dynamics, we observe a substantially faster growth from DCSCH and a higher saturation diameter when growing pillars with high aspect ratio. However, both compounds show similar behaviour with regards to the proximity effect. With regards to the composition of the deposits, we observe that the C/Si ratio is similar for both compounds and in both cases close to the initial molecular stoichiometry. The oxygen content in the DCSCH deposits is about double that of the SCH deposits. Only marginal chlorine is observed in the deposits of from DCSCH. We discuss these observations in context of potential approaches for Si deposition.
ALMA Pinpoints a Strong Overdensity of U/LIRGs in the Massive Cluster XCS J2215 at z = 1.46
Authors: Stach Stuart M. , Swinbank A. M. , Smail Ian , Hilton Matt , Simpson J. M. , Cooke E. A.
Published: November 2017

We surveyed the core regions of the z = 1.46 cluster XCS J2215.9−1738 with the Atacama Large Millimeter Array (ALMA) and the MUSE-GALACSI spectrograph on the Very Large Telescope (VLT). We obtained high spatial resolution observations with ALMA of the 1.2 mm dust continuum and molecular gas emission in the central regions of the cluster. These observations detect 14 significant millimeter sources in a region with a projected diameter of just ∼500 kpc (∼1′). For six of these galaxies, we also obtain 12CO(2–1) and 12CO(5–4) line detections, confirming them as cluster members, and a further five of our millimeter galaxies have archival 12CO(2–1) detections, which also place them in the cluster. An additional two millimeter galaxies have photometric redshifts consistent with cluster membership, although neither show strong line emission in the MUSE spectra. This suggests that the bulk (≥11/14, ∼80%) of the submillimeter sources in the field are in fact luminous infrared galaxies lying within this young cluster. We then use our sensitive new observations to constrain the dust-obscured star formation activity and cold molecular gas within this cluster. We find hints that the cooler dust and gas components within these galaxies may have been influenced by their environment, reducing the gas reservoir available for their subsequent star formation. We also find that these actively star-forming galaxies have dynamical masses and stellar population ages expected for the progenitors of massive, early-type galaxies in local clusters, potentially linking these populations.

Very-high-energy (VHE; > 100 GeV) gamma-ray emission from the blazar RGB J2243+203 was discovered with the VERITAS Cherenkov telescope array, during the period between 2014 December 21 and 24. The VERITAS energy spectrum from this source can be fitted by a power law with a photon index of 4.6 ± 0.5, and a flux normalization at 0.15 TeV of

However, due to scheduling constraints Swift-XRT observations were performed 67 hr after the VERITAS detection, rather than simultaneously with the VERITAS observations. The observed X-ray energy spectrum between 2 and 10 keV can be fitted with a power law with a spectral index of 2.7 ± 0.2, and the integrated photon flux in the same energy band is

Participatory design of citizen science experiments
Authors: Senabre Enric , Ferran-Ferrer Núria , Perelló Josep
Published: November 2017

This article describes and analyzes the collaborative design of a citizen science research project through cocreation. Three groups of secondary school students and a team of scientists conceived three experiments on human behavior and social capital in urban and public spaces. The study goal is to address how interdisciplinary work and attention to social concerns and needs, as well as the collective construction of research questions, can be integrated into scientific research. The 95 students participating in the project answered a survey to evaluate their perception about the dynamics and tools used in the cocreation process of each experiment, and the five scientists responded to a semistructured interview. The results from the survey and interviews demonstrate how citizen science can achieve a “cocreated” modality beyond the usual “contributory” paradigm, which usually only involves the public or amateurs in data collection stages. This type of more collaborative science was made possible by the adaptation of materials and facilitation mechanisms, as well as the promotion of key aspects in research such as trust, creativity and transparency. The results also point to the possibility of adopting similar codesign strategies in other contexts of scientific collaboration and collaborative knowledge generation

Este artículo describe y analiza el diseño colaborativo de un proyecto de investigación de ciencia ciudadana a través de la cocreación. Tres grupos de estudiantes de centros de educación secundaria y un equipo de científicos idearon de forma participada tres experimentos sobre comportamiento humano y capital social en espacios públicos y urbanos. El objetivo del estudio es abordar cómo pueden integrarse en una investigación científica el trabajo interdisciplinar y la atención a preocupaciones y necesidades sociales, así como la construcción colectiva de preguntas de investigación. Los 95 estudiantes participantes en el proyecto respondieron una encuesta para evaluar su percepción sobre las dinámicas y herramientas utilizadas en el proceso de cocreación de cada experimento, y los cinco científicos respondieron a una entrevista semiestructurada. Los resultados de las encuestas y entrevistas demuestran cómo la ciencia ciudadana puede alcanzar una modalidad «cocreada» más allá del paradigma habitual «contributivo», el cual únicamente suele implicar al público o amateurs en la recopilación de datos. Esta modalidad de ciencia más colaborativa con la ciudadanía fue posible gracias a la adecuación de materiales y mecanismos de facilitación, así como al fomento de aspectos clave en una investigación como pueden ser la confianza, la creatividad y la transparencia. Los resultados apuntan también hacia la posibilidad de adoptar estrategias similares de codiseño en otros contextos de colaboración científica y generación colaborativa de conocimiento
Faire feu de tout bois
Authors: Gauthier Christophe
Published: November 2017

Roland Topor n’a jamais souhaité être enfermé dans la seule profession de dessinateur, et l’une de ses principales caractéristiques est bien la manière dont il s’est approprié les industries culturelles de son temps, qu’il s’agisse du cinéma ou de la télévision, dans des genres symboliquement illégitimes (le dessin animé pas vraiment pour les enfants, la télévision pas tout à fait pour les adultes). Cette grande diversité l’a conduit à mettre en place des stratégies bien particulières. On en identifiera trois. La première concerne les réemplois multiples de ses dessins, dans des revues aux statuts eux-mêmes très divers. La deuxième intéresse le public, et le trouble intentionnel dans lequel La planète sauvage jette la critique de son temps, alors que l’on ne saurait considérer un film d’animation comme un objet qui ne soit pas destiné aux enfants. La troisième, enfin, vient perturber la place de l’auteur, tant les collaborations multiples auxquelles se livre Roland Topor semblent à contre-courant d’une représentation convenue d’un artiste unique détenant le contrôle sur son œuvre. Autant de manières de « désorienter » son travail, qui montrent combien l’utilisation des industries culturelles peut s’avérer féconde dans une démarche d’artiste qui a toujours cherché à s’affranchir des stéréotypes.
Dessiner à la télévision : Topor invité de Tac au Tac (1971-1972)
Authors: Tillier Bertrand
Published: November 2017

En 1971-1972, Roland Topor fut à trois reprises l’invité de l’émission de Jean Frapat, Tac au Tac , diffusée depuis 1969 à la télévision française. Ce jeu inspiré du cadavre exquis surréaliste avait pour principe de rassembler, sur un même plateau du service de la recherche de l’ORTF, des dessinateurs de presse et de bande dessinée, afin de les confronter, sous l’œil des caméras, à des dispositifs dialogiques graphiques. L’article analyse les contraintes ludiques inventées par Frapat et les conditions de production de son émission, en regard de son ambition visant à constituer une encyclopédie télévisée du dessin contemporain. L’étude s’emploie également à interroger la participation de Topor à ce programme et à évaluer la place de son propre univers dans cette configuration expérimentale.
Topor et Kubin : le symbolisme en partage ?
Authors: Goldberg Itzhak
Published: November 2017

L’article cherche à montrer les parallèles et les différences entre les univers symbolistes d’Alfred Kubin et de Roland Topor. Si l’essentiel de la recherche est consacré à Kubin, c’est que Topor, qui a connu cette œuvre à partir de 1962, ne cacha pas son admiration pour l’artiste autrichien. Les liens de Topor avec Kubin passent par l’héritage partagé d’une imagerie Mitteleuropa grinçante et hallucinée, mais aussi d’une pratique de l’écriture renvoyant à L’Autre côté . Toutefois, c’est probablement l’iconographie qui offre le terrain commun le plus important, car l’artiste français y reprend l’essentiel de la thématique symboliste de son aîné autrichien – et surtout celle convoquant la femme et la mort. Cependant, là où l’image de Kubin constitue un monde imaginaire dans lequel glisse le spectateur, chez Topor, la dérision et le regard critique obligent à la distanciation.
Topor et les jeux de l’art contemporain
Authors: Devaux Alexandre
Published: November 2017

La multiplicité des médias, supports et techniques caractérise l’œuvre de Topor. Avec le dessin et l’écriture, un crayon et du papier, il montre l’étendue des possibilités qu’offrent les outils de création. Le « multiple », Topor le revendique comme subversion de l’« unique ». Le sens, les significations, la fonction des êtres et des objets ne doivent être réduits, selon lui, aux seuls diktats de la société de consommation. L’œuvre d’art est un produit de communication. Sur ce terrain, tous les jeux et toutes les complexités individuelles sont possibles pour ouvrir la création, le champ de découvertes de nouvelles formes et significations. Topor a mis cette dynamique en œuvres, c’est-à-dire en formes, en livres et en actes divers. Cette dimension multiple de l’œuvre de Topor contribue à le faire se rapprocher de certaines avant-gardes artistiques de son temps et plus spécifiquement des Nouveaux Réalistes ou de Fluxus.
Hydroxylation and dimerization of zearalenone: comparison of chemical, enzymatic and electrochemical oxidation methods
Authors: Keller J. , Haase H. , Koch M.
Published: November 2017

Investigations of the metabolic pathway of mycotoxins by microsomal techniques are often laborious, causing an increasing demand for easy and rapid simulation methods. Thus, the non-microsomal oxidation technique of electrochemistry coupled online to mass spectrometry (EC/MS) was applied to simulate phase I biotransformation of theFusarium mycotoxin zearalenone (ZEA). The obtained transformation products were identified by high resolution mass spectrometry (FT-ICR) and HPLC-MS/MS. Transformation products (TPs) from EC/MS were compared to those of other oxidative methods, such as Fenton-like and Ce(IV) reactions and metabolites derived fromin vitro assays (human and rat liver microsomes). Electrochemical oxidisation of ZEA was achieved by applying a potential between 0 and 2,500 mV vs Pd/H2 using a flow-through cell with a boron-doped diamond working electrode. Several mono-hydroxylated TPs were generated by EC/MS and Fenton-like reaction, which could also be found in microsomalin vitro assays. EC and Ce(IV) led to the formation of structurally different ZEA dimers and dimeric quinones probably connected over covalent biaryl C-C and C-O-C bonds. Although the dimerization of phenolic compounds is often observed in natural processes, ZEA dimers have not yet been reported. This is the first report on the formation of stable ZEA dimers and their related quinones. The tested non-microsomal methods, in particular EC/MS, could be useful in order to predict the biotransformation products of mycotoxins, even in cases where one to one simulation is not always feasible.
Cutting Edge: c-Maf Is Required for Regulatory T Cells To Adopt RORγt+ and Follicular Phenotypes
Authors: Wheaton Joshua D. , Yeh Chen-Hao , Ciofani Maria
Published: November 2017

Regulatory T cells (Tregs) adopt specialized phenotypes defined by coexpression of lineage-defining transcription factors, such as RORγt, Bcl-6, or PPARγ, alongside Foxp3. These Treg subsets have unique tissue distributions and diverse roles in maintaining organismal homeostasis. However, despite extensive functional characterization, the factors driving Treg specialization are largely unknown. In this article, we show that c-Maf is a critical transcription factor regulating this process in mice, essential for generation of both RORγt+ Tregs and T follicular regulatory cells, but not for adipose-resident Tregs. c-Maf appears to function primarily in Treg specialization, because IL-10 production, expression of other effector molecules, and general immune homeostasis are not c-Maf dependent. As in other T cells, c-Maf is induced in Tregs by IL-6 and TGF-β, suggesting that a combination of inflammatory and tolerogenic signals promote c-Maf expression. Therefore, c-Maf is a novel regulator of Treg specialization, which may integrate disparate signals to facilitate environmental adaptation.
The Mod Two Cohomology of the Moduli Space of Rank Two Stable Bundles on a Surface and Skew Schur Polynomials
Authors: Scaduto Christopher W. , Stoffregen Matthew
Published: November 2017

We compute cup-product pairings in the integral cohomology ring of the moduli space of rank two stable bundles with odd determinant over a Riemann surface using methods of Zagier. The resulting formula is related to a generating function for certain skew Schur polynomials. As an application, we compute the nilpotency degree of a distinguished degree two generator in the mod two cohomology ring. We then give descriptions of the mod two cohomology rings in low genus, and describe the subrings invariant under the mapping-class group action.
Bounds on Multiple Self-avoiding Polygons
Authors: Hong Kyungpyo , Oh Seungsang
Published: November 2017

A self-avoiding polygon is a lattice polygon consisting of a closed self-avoiding walk on a square lattice. Surprisingly little is known rigorously about the enumeration of self-avoiding polygons, although there are numerous conjectures that are believed to be true and strongly supported by numerical simulations. As an analogous problemto this study, we considermultiple self-avoiding polygons in a confined region as a model for multiple ring polymers in physics. We find rigorous lower and upper bounds for the number pm×n of distinct multiple self-avoiding polygons in the m × n rectangular grid on the square lattice. For m = 2, p2×n = 2n−1 − 1. And for integers m, n ≥ 3,
El conocimiento práctico del profesor: ¿cuándo empieza todo?
Authors: Ibarrola-García Sara
Published: November 2017

El conocimiento práctico permite al docente poner en relación lo que ocurre en su aula con contenidos teóricos. Esto facilita la coherencia pedagógica e impulsa la introducción de mejoras en la práctica. El profesor construye su conocimiento práctico cuando lo acepta como una característica básica de su profesión. También si ha aprendido cómo activar los procesos de reflexión que le permiten establecer sinergias entre el saber y el hacer. Todo ello requiere de primeros pasos en las aulas universitarias. Este es el punto de partida de este artículo: ¿se puede trabajar el conocimiento práctico desde la formación inicial del docente? En primer lugar, en este trabajo se justifica y analizan estrategias metodológicas que posibilitan que el alumnado desarrolle progresivamente hábitos reflexivos estableciendo por sí mismo relaciones entre los contenidos de las asignaturas y la práctica educativa. En segundo lugar, se describe una experiencia llevada a cabo en la asignatura “Diseño, desarrollo e innovación del currículum”. Se recogen las percepciones sobre los resultados de aprendizaje alcanzados por los alumnos implicados. Estos resultados sugieren que la introducción de estrategias metodológicas para relacionar la teoría y la práctica ha favorecido la adquisición de los contenidos de la asignatura al mismo tiempo que algunas destrezas y actitudes reflexivas que se detallan.

Published: November 2017

En este trabajo presentamos los resultados alcanzados por el equipo de profesores implicados en la docencia de las asignaturas del primer curso y primer semestre del Grado en Ingeniería en Diseño Industrial y Desarrollo de Producto de la Universidad de Zaragoza (Estética e Historia del Diseño, Expresión Artística, Matemáticas e Informática) empleando Erúbricas para evaluar los trabajos de módulo desde el curso 2011-2012. La experiencia ha tenido como objetivo fundamental la planificación, coordinación e implementación de un sistema de evaluación basado en el uso de rúbricas para la calificación final de los trabajos de módulo, modelo docente de trabajo interdisciplinar y colaborativo implantado desde el curso 2008-2009, que da respuesta a la organización modular del Grado, y en los que se trabaja, de forma coordinada, contenidos y competencias del primer semestre. El proyecto surge de la necesidad de crear un sistema de evaluación de los trabajos de módulo que integre tanto la evaluación de las competencias específicas como las transversales. De esta forma, se han diseñado un total de ocho Erúbricas, cuatro para las competencias transversales y cuatro para las específicas, junto con una encuesta para evaluar la experiencia. El proyecto ha supuesto una mejora de la práctica evaluativa de los trabajos por módulos, profundizando en la misma y en la importancia de cada competencia, estableciendo criterios comunes de evaluación entre el equipo docente, detectando necesidades de aprendizaje y proporcionando al alumno una herramienta para su planificación.
Aprender creando: “Factoría Creativa” en las aulas universitarias

Published: November 2017

La experiencia de innovación metodológica “Factoría Creativa” que presentamos en este artículo se ha desarrollado durante los cursos 2011/2012 y 2012/2013 dentro de la asignatura de Didáctica general en el Grado de Educación Social en la Universidad del País Vasco (UPV/EHU) y en los grupos de euskera y castellano. El propósito central que se ha perseguido ha sido proporcionar al alumnado un contexto formativo y una oportunidad de aprendizaje para vivir y analizar el uso de esta metodología a la hora de realizar un diagnóstico de necesidades, de generar ideas innovadoras y de diseñar proyectos de intervención socioeducativos. La evaluación de la experiencia evidencia que trabajar con esta metodología genera en el alumnado un aprendizaje creativo, motivador, significativo y funcional. La experiencia se ha desarrollado dentro de la modalidad formativa de “seminarios” en la que el grupo grande de clase se subdivide en grupos de aproximadamente quince personas para realizar tareas de profundización o de complementariedad a la modalidad magistral. Este tipo de agrupamiento asegura contar con mayores posibilidades de interacción comunicativa y de participación distendida y abierta por parte de los y las estudiantes.En este artículo relatamos la fundamentación teórica, el procedimiento metodológico seguido así como su fundamento en el mundo socioeducativo del que lo hemos incorporado, los resultados arrojados por el proceso de evaluación realizado con el alumnado durante el proceso de trabajo, las conclusiones más relevantes a las que hemos llegado así como las líneas de mejora a introducir para los próximos años.

Una (re)visión de la tutoría universitaria: la percepción de estudiantes y tutores de estudios de Grado.
Authors: Martínez Clares Pilar , Pérez Cusó Javier , Martínez Juárez Mirian
Published: November 2017

En una (re)visión de la tutoría universitaria, comprobamos que ésta reaparece en la Educación Superior -con las nuevas directrices europeas- como un elemento de calidad e innovación que facilita el proceso de acompañamiento necesario para contribuir al desarrollo y formación integral de los estudiantes, favoreciendo, así mismo, el nuevo enfoque educativo centrado en el alumnado y su aprendizaje. Este trabajo profundiza en las percepciones, creencias y relaciones que estudiantes y tutores de diferentes estudios de Grado, pertenecientes a un Plan Especial de Tutoría Universitaria, tienen sobre ésta en el primer año de ingreso. El análisis y reflexión de aspectos básicos de la misma permite que sus verdaderos protagonistas, estudiantes y tutores, planteen una retroalimentación, en forma de propuestas de mejora, en beneficio de su óptimo desarrollo. Se concluye con la necesidad de contemplar la tutoría como un proceso sistemático, planificado, integrado, intencional, continuo, dinámico y, sobre todo, reconocido, ya que actualmente responde a un derecho del EEES y se constituye como un factor de calidad del mismo, por lo que no puede dejarse únicamente en manos voluntariosas, sino que debe concebirse como un asunto institucional. Para ello se hace necesario la creación de una estructura organizativa que garantice tanto su funcionamiento como la respuesta adecuada a demandas concretas. Se trata, por tanto, de dotar de contenido a la tutoría para conferirle sentido, coherencia y continuidad.

Published: November 2017

En este trabajo se evalúa la usabilidad de herramientas en línea utilizadas en la educación universitaria. De todas las posibles herramientas se centra en especial en las e-Rúbricas utilizadas para la autoevaluación y la evaluación entre pares. Los resultados muestran un alto grado de usabilidad de esta herramienta y de satisfacción por parte de estudiantes que la emplean como recurso en su formación académica. Desde la perspectiva del diseño y de la accesibilidad se señalan los aspectos a mejorar en las e-Rúbricas evaluadas, sin entrar en aspectos de contenido de las mismas, o de los indicadores empleados, o de otras características propias de los instrumentos de evaluación, sino desde la perspectiva técnica de manejo en la web. Los resultados se han obtenido de la aplicación de un instrumento en línea del que se tiene un coeficiente de fiabilidad alfa de Cronbach de 0,889. El instrumento utilizado consta de unas pocas preguntas descriptivas sobre quien contesta y qué herramienta evalúa, seguidas de 22 enunciados en una escala Likert del 1 al 5. Los enunciados están dispuestos alternativamente en forma directa (1 peor valoración, a 5 mejor valoración), e indirecta (1 mejor valoración, a 5 peor valoración). Los resultados muestran que más del 50% de los que completan el cuestionario valoran la usabilidad de las herramientas evaluadas positivamente, en especial la e-Rúbrica, y menos del 20% valoran la usabilidad como baja. Este cuestionario puede utilizarse en la evaluación de la usabilidad de cualquier herramienta en la Web.

Abstract. How environmental change affects a species’ phenotype is crucial not only for taxonomy and biodiversity assessments but also for their application as (paleo-)ecological indicators. Previous investigations addressing the impact of climate and hydrochemical regime on ostracod valve morphology have yielded quite contrasting results. Frequently identified ecological factors influencing carapace shape are salinity, cation and sulphate concentrations and alkalinity. Here, we present a thorough approach integrating data from carapace outline and surface details of the ubiquitous Neotropical cytheroidean ostracod species Cytheridella ilosvayi, as well as several climatic and hydrochemical variables, in order to investigate a potential link between morphology and environmental conditions. A previous study lately demonstrated considerable biogeographical variation in valve morphology among Floridian, Mexican and Brazilian populations of this species. We hypothesize that the climatic differences between the regions it inhabits and associated differences in hydrochemical regimes have influenced valve morphology and eventually led to biogeographically distinctive groups. Generalized least-squares Procrustes Analyses based on outline and structural features were applied to left and right valves of adult females and males. The analyses identified relative carapace length and shape symmetry as most important morphological characteristics representing shape change across all datasets. Two-block partial least-squares analyses and multiple regressions indicate strong relationships between morphological and environmental variables, specifically with temperature seasonality, annual precipitation and chloride and sulphate concentrations. We hypothesize that increased temperature seasonality slowed down growth rates during colder months, potentially triggering the development of shortened valves with well-developed brood pouches. Differences in chloride and sulphate concentrations, related to fluctuations in precipitation, are considered to affect valve development via controlling osmoregulation and carapace calcification. These factors represent hitherto unknown drivers for ostracod ecophenotypy and emphasise that environmental predictors for morphological variability are not consistent across non-marine ostracods.

Abstract. A meteorological numerical model can be a powerful tool to complement laboratory experiments applied to atmospheric sciences, but it needs to be adapted in order to represent flows generated in laboratory. This paper presents such an adaptation of the atmospheric non-hydrostatic model Meso-NH. The usually neglected viscous diffusive fluxes have been added to the model’s equations, along with the coding of an explicit bottom no-slip boundary condition was implemented. These implementations are validated against exact solutions of ideal flows. Meso-NH is then used in a configuration matching a laboratory experiment performed in the CNRM large stratified water flume meant to reproduce a neutral atmospheric boundary layer. The model is run for the first time in an explicit mode (Direct Numerical Simulation – DNS) at a very high resolution (1 mm) over a large grid. The comparison with the experimental data shows that the boundary layer height and vertical profiles of mean velocity are well captured by the model. This result further validates the implementations carried out in Meso-NH which can now be used in a DNS mode to simulate channel flows. The joint use of Meso-NH and laboratory experiments, along with the possibility to run DNS with Meso-NH, could lead to new findings or improvements in the field of atmospheric sciences.
Shaping (Global) Leaders or Creating (Global) Citizens? Considering the Competing Purposes of Higher Education
Authors: Cole Rose
Published: November 2017

Focusing mainly on one particularly rich and illustrative case study—the University of Virginia—and grounded in a larger ethnographic study of higher education for citizenship, this research examines the frameworks of education for citizenship/global citizenship versus education for (global) leadership with empirical data from institutional policies and documents, courses and supplemented with observations and interviews with faculty and students. This paper makes two main claims. First, that the contemporary emphasis on leadership development within U.S. institutions of higher education is a symptom of and contributes to the perception of higher education as a private good instead of a public good. The second, related argument is that higher education for leadership has been conflated with higher education for citizenship.
The Misinformation Effect and the Type of Misinformation: Objects and the Temporal Structure of an Episode
Authors: Han Yuhwa
Published: November 2017

This study aimed to modify the stimulus set used to test the misinformation effect developed by Takarangi and her colleagues. The narratives and memory tests were modified to include items asking about specific objects in the story and about the temporal structure of the events. To examine whether the new material could produce the misinformation effect, the author had 72 participants watch a video, read a narrative with misinformation about objects in the video or the temporal sequence in the video, and then take a memory recognition test. This study showed that the misinformation effect could be produced by the temporal misinformation, suggesting that participants were misled by the misinformation regardless of the type of misinformation. As a result of using the modified narratives and the memory test, researchers could examine the effects of multiple types of misinformation.
Out of Thin Air: Configurability, Choreography, and the Air Guitar World Championships
Authors: McDaniel Byrd
Published: November 2017

In annual air guitar competitions, performers choreograph routines that simulate and exaggerate gestures needed to play “real” guitar. Before competitions, they edit and alter popular music to facilitate routines. Based on fieldwork at local and national competitions in the United States and the international competition in Finland, my research demonstrates connections between remix aesthetics offstage and choreographies onstage, where competitors configure, conjure, and consume popular music. Rather than viewing competitions as evidence of uninhibited interpretive agency of popular music consumers, I argue that power differentials emerge where identity, sensibility, physical skills, and acquired skills determine types and degrees of participation possible for practitioners.

The bacterium ‘Candidatus Liberibacter solanacearum’ is a recent plant pathogen of several crops in Solanaceae and Apiaceae and is associated with economically important diseases. The bacterium is a carrot seed borne pathogen that can also be transmitted from potato mother tubers and by psyllid vectors. The psyllid Bactericera trigonica Hodkinson was described carrying CaLso associated with vegetative disorders in carrot and celery crops in Spain and its competence to transmit this phloem-limited bacterium among vegetables is currently being investigated. Here electrical penetration graphs showed that B. trigonica fed in the phloem of carrot and celery and probed the phloem in potato, but not in tomato plants. The bacterium was efficiently transmitted to carrot and celery plants when either single B. trigonica or groups of ten fed on these species. An inoculation access period of 24 hours was sufficient for a single B. trigonica to transmit the bacterium to carrot (67.8%), celery (21.1%) and eventually to potato and tomato (6.0%). Higher transmission rates were obtained with 10 individuals on celery (100%), carrot (80%), potato (10%) and tomato (10%). Bactericera trigonica laid eggs, and the hatched nymphs develop into adult on carrot and celery, but not on potato and tomato. CaLso was detected in 20% of the eggs laid by females carrying the bacterium. The results confirmed that B. trigonica is a vector of the bacterium to carrot and celery, and it is discussed the potential role of this psyllid in the transmission of the pathogen to potato and tomato plants.
