Pensando en espiral
Authors: Comba Leonardo
Published: December 2018

El territorio ancestral del cual provenimos cuenta con maravillosas muestras de lo que conocemos como arte rupestre, grabados y pinturas hechos sobre superficies rocosas en épocas que se saben remotas, aunque en su mayoría no puedan ser datadas con precisión, realizadas por antiguos habitantes de lo que hoy llamamos Colombia. En el centro del país, en los departamentos de Cundinamarca y Boyacá principalmente, permanece la cultura indígena que encontraron los invasores europeos a su llegada en el siglo XVI, los Mhuysqas. A pesar de todo, la cultura Mhuysqa no está extinta, como se cree generalmente, y cada vez surgen más individuos y colectivos que se reconocen pertenecientes a esta etnia.Actualmente son cinco las comunidades reconocidas legalmente por el estado como pertenecientes a la cultura Mhuysqa, en las localidades de Bosa y Suba en Bogotá, y en las poblaciones de Cota, Chía y Sesquilé en el departamento de Cundinamarca. Según datos del Censo Nacional de Población realizado por el Dane en el año 2005, de 14.051 indígenas Mhuysqas registrados, 5.713 residen Bogotá, 2.410 en Cota, en Chía 1.843 y en otros contextos urbanos se encuentran 10.243 personas (Ministerio del Interior, S.F., p.1). Según este censo, en Boyacá se contabilizaron 212 Mhuysqas en Tunja y 223 en Sogamoso.
Los crímenes contra defensores de derechos humanos son crímenes de lesa humanidad
Authors: Latorre Sebastian
Published: December 2018

Los casos en los que un defensor o defensora de derechos humanos, o un reclamante de tierras son asesinados, en adelante, deberán ser catalogados como crímenes de lesa humanidad.Asesinatos, torturas, desapariciones, etc., ejecutadas contra un número de personas, por atreverse a reivindicar los derechos humanos o la recuperación de sus tierras.Los delitos de lesa humanidad contienen un elemento material (ataque masivo o sistemático contra una población civil) y otro de orden subjetivo (el autor debe tener conocimiento de la existencia del ataque). Al ser catalogados los crímenes contra defensores de derechos humanos como crímenes de lesa humanidad, nos abre puertas importantes para iniciar acciones legales que permitan disminuir los índices de impunidad reinantes en las investigaciones en Colombia, recursos y acciones que justamente por el pasar del tiempo ya no era procedente interponer, pero que atendiendo a la imprescriptibilidad que cobija este tipo de delitos, tendrán que surtir trámites ante los diferentes despachos judiciales; igualmente esta calificación abre camino para que casos resientes puedan ser investigados por la Corte Penal Internacional.
Creatividad e innovación grastronómica
Authors: Sabogal Nicolas
Published: December 2018

La creatividad es una forma de desarrollar la identidad del ser humano, donde su objetivo es demostrar la evolución de algo ya existente. Para muchos la creatividad solo es una forma de ser “novedoso”, a partir de la expresión de perspectivas distintas de algo ya establecido, de forma empírica y arbitraria; pero, lo que en realidad respecta a un acto creativo es el echo de innovar respecto a elementos ya establecidos y usados de acuerdo a corrientes científicas, sociales y culturales. Hay cabida a pensamientos escépticos que obligan al creador-innovador a explorar diferentes campos para llegar a su producto pensado.
WALEKERU Tejiendo cultura mediante el patronaje mágico
Authors: Marínez Pereira Carolina , Romero Mora Karol
Published: December 2018

Formar parte del semillero FibrArte siempre fue uno de nuestros objetivos al comenzar nuestra carrera, así que al momento de decidir cuál sería nuestro proyecto de grado, no lo pensamos mucho y decidimos que trabajaríamos en el semillero con la comunidad indígena Wayuú y la tejeduría de su mochila. Teniendo en cuenta que esta es una de las culturas que son consideradas patrimonio nacional y que por nada del mundo de debe dejar perder sus tradiciones o reemplazar sus procesos perdiendo su identidad. De esta manera supimos que el problema radicaba en buscar la forma de hacer este rescate cultural y fue cuando nos dimos a la tarea de pensar ¿Cómo diseñar una colección de vestuario experimental, interpretando la simbología de cinco clanes  Wayuu, provenientes de las comunidades de Tocoromana, Loma Fresca y La Guasima y combinar su tejeduría con el patronaje mágico? Teniendo en cuenta que el patronaje mágico ha sido nuestra especialidad en el trayecto de nuestra profesión como un medio de expresión y una técnica que permite abarcar absolutamente todas las ideas por medio de pliegues y técnicas parecidas al origami, pero aplicadas en el vestuario.
Estrategia de comunicación diseñada a partir de una narrativa transmedia, que fortalezca el reconocimiento de la Casa Museo Tequendama y sus Alredeores

Published: December 2018

Durante el 2013 fuimos testigos de un proyecto de restauración arquitectónica y ecológica en el imponente Salto del Tequendama. El proyecto liderado por la Fundación Granja el Porvenir, busca entre otras cosas, revivir la magia que transmitió a lo largo del tiempo este mítico y emblemático lugar, ubicado en el municipio de Soacha, Cundinamarca (Colombia) cerca de San Antonio del Tequendama, a 56km de Bogotá. La caída del salto tiene aproximadamente unos 2.467 metros de altura (Boussingault, Jean Baptiste Joseph Dieudonné & Koppel de León, Alexander, 2011) y es sin duda una imponente maravilla natural, que no está sola, pues al frente la observa una hermosa casa de cuatro pisos, de arquitectura francesa, construida entre 1923 y 1927, por Orden del Presidente de la época, el General Pedro Nel Ospina. La casa que fue construida inicialmente para convertirse en estación central del ferrocarril de la Sabana.Que luego funcionó como un ostentoso hotel integrado por habitaciones de primera y segunda clase, después se convirtió en un elegante restaurante y bar, pero lastimosamente, en la década de los ochenta, a causa de la contaminación del río Bogotá, la casa cerró sus puertas y fue abandonada hasta adquirir una mala reputación. En el 2012 la Fundación Granja Ecológica el Porvenir, encabezada por la médica veterinaria María Victoria Blanco, se adueñó de la casa y desde entonces ha iniciado un proceso de restauración arquitectónica, ecológica y cultural que busca convertir la casa, en museo de la biodiversidad de fauna y flora. Alrededor del salto y la Casa del Tequendama, se instala un denso bosque de niebla, que funciona como un buen receptor de carbono y gran productor de agua y oxígeno; su ecosistema requiere de animales silvestres que se encuentran en peligro de extinción, a causa del tráfico animal, la inadecuada actividad agropecuaria y la minería ilegal. Por fortuna, la Fundación Granja Ecológica el Porvenir se ha comprometido con la conservación y el rescate del ecosistema, devolviéndole al entorno especies nativas, víctimas del tráfico animal. La fundación realiza actividades lúdicas que buscan informar a jóvenes y adultos, sobre el contexto histórico, cultural y ecológico que representa el lugar, con el fin de generar conciencia en las actuales y futuras generaciones para proteger nuestros recursos naturales, y rescatar la memoria ancestral del país.

Cuando me pidieron escribir un artículo sobre mi aprendizaje en la ingeniería de papel, francamente no sabía por dónde empezar. Mientras me movilizaba de la universidad a la casa, empecé a recordar mi transcurso por la academia y colegio buscando una idea para empezar a escribir. Con aquellos  recuerdos yo no paraba de reír solo, irremediablemente la gente se extrañaba de verme en una actitud jocosa, los pasajeros habrían de pensar que tengo un problema mental, y una solución creativa para evitar la marginación social fue ponerme los audífonos, recordar mi infancia, y entablar una conversación conmigo, preguntándome lo siguiente:¿Por qué me gusta hacer libros Pop Up y desarrollar mis proyectos universitarios con ingeniería de papel?Como respuesta histórica a la anterior pregunta, recuerdo aquel oxidado gusto escolar por ir a la biblioteca en la hora de descanso, me gustaba ver libros ilustrados de biología y periódicos, sus coloridas historietas de la última página lograban sacarme una sonrisa en aquel solitario lugar. Para este tiempo recolectaba: volantes, afiches, revistas y libros para luego “descuartizarlos”, mis favoritos eran los catálogos turísticos y las revistas  de “Los Testigos de Jehová”, allí encontraba una gran riqueza de recursos gráficos para crear mundos e historias. Recortaba siluetas y realizaba collage. Entre recorte y siluetas armaba historias, algunas enredadas  y otras  perturbadoras, no era muy armónico usar figuras religiosas y fusionarlas con estampillas de Dragon Ball Z.

Antiemetic management preferences for paramedic providers: A cross-sectional survey
Authors: Caffey Matthew R , Maria Sonja , Brewster Lyle , Ireland Matthew
Published: December 2018

IntroductionParamedics are commonly called to complaints of nausea and vomiting with the treatment of these conditions being either antiemetics or palliative measures.  Historically, there have been several antiemetics available to paramedics across Australia and New Zealand with their use varied dependent on each region of practice. The objective of this research was to create a snapshot in time and determine which antiemetics have been used by paramedics, their preferences of use, and their beliefs regarding each antiemetic.MethodsUsing a cross-sectional and online survey, paramedics from across Australia and New Zealand were invited to answer questions regarding their demographics, antiemetics used in practice and then preferences regarding these antiemetics. A 5-point Likert scale and free text qualitative answers were also used to identify particular views and beliefs on the efficacy of the varying antiemetics.Results476 paramedics participated in the study. The participants were predominantly male n=344 (72.3%).  Ondansetron was found to be the most preferred antiemetic for general use in nausea and vomiting n = 378 (82%) with the second line choice being metoclopramide n = 62 (13.4%).  Exceptions to this were for prochlorperazine, which showed a high preference for nausea related to migraine n=179 (56.2%) or vertigo or motion sickness n=243 (42%).ConclusionPreferences and decision making for choosing ondansetron over other antiemetics were primarily its efficacy, minimal side effects and availability.  An exception to ondansetron’s preferred usage was prochlorperazine, which was the preferred medication for cases involving nausea with motion sickness or vertigo.  Historically, metoclopramide has been the most common antiemetic in paramedic practice but is not generally preferred as first line due to its contraindications, perceived lower efficacy over other antiemetics and risk of side effects.

Governança em cenários de escassez hídrica
Authors: De Queiroz Fábio Albergaria , Tiburcio James Augusto Pires
Published: December 2018

Water is an increasingly scarce resource. One of the most noteworthy discursive features of the last decades has been a growing awareness of water-related issues as a critically important component for regional stability. This situation helps to explain why, in many cases, water management involves political, economic, social, environmental and even military issues. But, in what intensity? This article analyzes the cases of Southern Africa and the Jordan River Basin due to their prevailing condition of water scarcity. In order to verify the role developed by the mechanisms of governance in accommodating the interests of the riparian states, the Hydropolitical Complexes Theory was applied. Inferences demonstrated a trend towards cooperation in Southern Africa that is due to the successful institutionalization of management mechanisms capable of minimizing potential for conflicts. On the other hand, in the Jordan Basin, the struggle to control water resources has been a significant factor in sustaining tension among riparian countries.
Hungria: O Estado de Direito em Crise?
Authors: Duarte Mariana Carmo
Published: December 2018

Between 2010 and 2011, the Fidesz-KDNP government carried out a number of legal, social and political reforms, including voting in a new constitution. Through analysis of this new constitution and amendments made to its predecessor, this article aims to understand the influence of the recent changes to the Hungarian constitutional framework with regard to the country’s rule of law. Based on the theoretical definition of the rule of law, it can be argued that principles such as balance of power, constitutionality of laws, legality of administration, and independence of the judiciary and the media have been undermined in Hungary. Personal dignity, freedom, justice and security have also been undermined. As a result of these decisions, the number of voices critical of Orbán’s government has grown. Among their numbers stands the European Union, which sees Hungary as the first Member State to deviate from the union’s democratic values
Gender and Sexuality in Islamic Teachings vs. Human Rights 2017
Authors: Khattab Fatma
Published: December 2018

Given recent changes in the political leadership of Muslim societies, it can be difficult to follow who got which hand on women’s issues, let alone just how women’s issues figure in political speeches from the Liberal to the most conservative. Meanwhile, when it comes to the laws and regulations on women’s issues, not much has been done to empower women to decide what is best for them. It’s only an appealing matter to discuss more or less, depending on the political need, while recent reports describe the city of Cairo as one of the least safe cities for women. Following the Arab Spring, which pushed many to reconsider the fight for democracy and human rights, socio-economic conditions have been worsening for both men and women, with those in the latter category suffering the most. We may find it challenging to track improvements in the area of women’s rights as long as the same old-new religious speech calls on women to keep their faith and patience for God’s sake, for a better future for their body, and for the dignity of their mind and soul. This paper discusses the current status of women’s rights in Muslim societies and how policy processes are informed by religious justification.

Dark Molecular Gas in Simulations of z ∼ 0 Disk Galaxies
Authors: Li Qi , Narayanan Desika , Davè Romeel , Krumholz Mark R.
Published: December 2018

The H2 mass of molecular clouds has traditionally been traced by the CO(J = 1−0) rotational transition line. This said, CO is relatively easily photodissociated and can also be destroyed by cosmic rays, thus rendering some fraction of molecular gas to be “CO-dark.” We investigate the amount and physical properties of CO-dark gas in two z ∼ 0 disk galaxies and develop predictions for the expected intensities of promising alternative tracers ([C i] 609 μm and [C ii] 158 μm emission). We do this by combining cosmological zoom simulations of disk galaxies with thermal-radiative-chemical equilibrium interstellar medium (ISM) calculations to model the predicted H i and H2 abundances and CO (J = 1−0), [C i] 609 μm, and [C ii] 158 μm emission properties. Our model treats the ISM as a collection of radially stratified clouds whose properties are dictated by their volume and column densities, the gas-phase metallicity, and the interstellar radiation field (ISRF) and CR ionization rates. Our main results follow. Adopting an observationally motivated definition of CO-dark gas, i.e., H2 gas with W
CO < 0.1 K km s−1, we find that a significant amount (≳50%) of the total H2 mass lies in CO-dark gas, most of which is diffuse gas, poorly shielded due to low dust column density. The CO-dark molecular gas tends to be dominated by [C ii], though [C i] also serves as a bright tracer of the dark gas in many instances. At the same time, [C ii] also tends to trace neutral atomic gas. As a result, when we quantify the conversion factors for the three carbon-based tracers of molecular gas, we find that [C i] suffers the least contamination from diffuse atomic gas and is relatively insensitive to secondary parameters.
A Theory for the Variation of Dust Attenuation Laws in Galaxies
Authors: Narayanan Desika , Conroy Charlie , Davé Romeel , Johnson Benjamin D. , Popping Gergö
Published: December 2018

In this paper, we provide a physical model for the origin of variations in the shapes and bump strengths of dust attenuation laws in galaxies by combining a large suite of cosmological “zoom-in” galaxy formation simulations with 3D Monte Carlo dust radiative transfer calculations. We model galaxies over three orders of magnitude in stellar mass, ranging from Milky Way–like systems to massive galaxies at high redshift. Critically, for these calculations, we employ a constant underlying dust extinction law in all cases and examine how the role of geometry and radiative transfer effects impacts the resultant attenuation curves. Our main results follow. Despite our usage of a constant dust extinction curve, we find dramatic variations in the derived attenuation laws. The slopes of normalized attenuation laws depend primarily on the complexities of star-to-dust geometry. Increasing fractions of unobscured young stars flatten normalized curves, while increasing fractions of unobscured old stars steepen curves. Similar to the slopes of our model attenuation laws, we find dramatic variation in the 2175 Å ultraviolet bump strength, including a subset of curves with little to no bump. These bump strengths are primarily influenced by the fraction of unobscured O and B stars in our model, with the impact of scattered light having only a secondary effect. Taken together, these results lead to a natural relationship between the attenuation curve slope and 2175 Å bump strength. Finally, we apply these results to a 25 Mpc h
−1 box cosmological hydrodynamic simulation in order to model the expected dispersion in attenuation laws at integer redshifts from z = 0 to 6. A significant dispersion is expected at low redshifts and decreases toward z = 6. We provide tabulated results for the best-fit median attenuation curve at all redshifts.
Successive Flux Rope Eruptions from δ-sunspots Region of NOAA 12673 and Associated X-class Eruptive Flares on 2017 September 6
Authors: Mitra Prabir K. , Joshi Bhuwan , Prasad Avijeet , Veronig Astrid M. , Bhattacharyya R.
Published: December 2018

In this article, we present a multiwavelength analysis of two X-class solar eruptive flares of classes X2.2 and X9.3 that occurred in the sigmoidal active region NOAA 12673 on 2017 September 6, by combining observations of Atmospheric Imaging Assembly and Helioseismic Magnetic Imager instruments on board the Solar Dynamics Observatory. On the day of the reported activity, the photospheric structure of the active region displayed a very complex network of δ-sunspots that gave rise to the formation of a coronal sigmoid observed in the hot extreme-ultraviolet channels. Both X-class flares initiated from the core of the sigmoid sequentially within an interval of ∼3 hr and progressed as a single sigmoid-to-arcade event. Differential emission measure analysis reveals strong heating of plasma at the core of the active region right from the preflare phase, which further intensified and spatially expanded during each event. The identification of a preexisting magnetic null by non-force-free-field modeling of the coronal magnetic fields at the location of early flare brightenings and remote faint ribbon-like structures during the preflare phase, which were magnetically connected with the core region, provide support for the breakout model of solar eruption. The magnetic extrapolations also reveal flux rope structures before both flares, which are subsequently supported by the observations of the eruption of hot extreme-ultraviolet channels. The second X-class flare diverged from the standard flare scenario in the evolution of two sets of flare ribbons, which are spatially well separated, providing firm evidence of magnetic reconnections at two coronal heights.
Three new species of Entoloma subgenus Pouzarella from China based on morphological and molecular data
Authors: He Xiao-Lan , Horak Egon , Wang Di , Peng Wei-Hong , Gan Bing-Cheng
Published: December 2018

In the present paper, three additional species of EntolomasubgenusPouzarella viz. E.erectoides, E.griseocarpum and E.rubropilosum are described from China. E.rubropilosum is a typical species in section Pouzarella; E.griseocarpum and E.erectoides are members of sect. Dysthales. The taxa are further confirmed by ITS, RPB2, LSU and mtSSU analyses and phylogenetic relationships with other Entolomasubgen.Pouzarella species are also discussed. ITS sequence analysis showed that the sizes of the entire ITS region and ITS1 are remarkably divergent, while the ITS2 is conserved in length within Entolomasubgen.Pouzarella. Molecular analyses, based on the combined dataset, demonstrated that species diversity of subgen.Pouzarella in China is much higher than previously thought, in the present study twenty phylogenetic species from China are taken into consideration. On the other hand, morphological and molecular analyses suggested that classification of Entolomasubgen.Pouzarella probably has to be fundamentally re-adjusted based on additional data.
Pour en finir avec les Calcurini
Authors: Claverie Pierre-Vincent
Published: December 2018

Depuis cinq siècles, les historiens débattent de l’identité des Calcurini qui tentèrent de subjuguer le port de Ceuta en 1234. Le présent article tente de faire la lumière sur cette énigme, en confrontant les hypothèses formulées à propos des Calcurini évoqués par les sources génoises. Une analyse critique permet de repousser les conclusions des arabisants et de confirmer l’origine catalane assignée naguère aux Calcurini par Ch.-E. Dufourcq. Tout pousse à voir dans ces marins expérimentés des matelots colliourencs aux ordres du seigneur de Roussillon, Nunó Sanç. Une série de traités signés par l’intéressé avec la République de Gênes explique le comportement chevaleresque des Calcurini lors de leur rencontre avec une escadre génoise devant Ceuta en août 1234.
Perros contra lobos. Ideología política y ¿sátira antinobiliaria? en una obra de Alonso de Palencia
Authors: Corral Sánchez Nuria
Published: December 2018

El presente trabajo profundiza en los contenidos ideológicos de la Batalla campal de los perros contra los lobos, un relato fabulístico de Alonso de Palencia compuesto en torno a 1456. Pondremos especial atención en los aspectos de crítica contra la alta nobleza castellana, que aparecería animalizada, según la interpretación de diversos autores. Más allá de su importancia como ejercicio de estilo, frecuentemente subrayada en otros estudios, mediante el análisis léxico hacemos énfasis en la presencia de intensos discursos políticos. La identificación y el estudio crítico de los mismos nos permitirán ahondar en el pensamiento del autor respecto a la sociedad de la época, plasmado en ideales como la disciplina, el consenso y el mérito, que, al no corresponderse con las actuaciones de parte de la nobleza, reflejarían asimismo la intención satírica de Palencia.
Dos frontals d’altar i l’acta de consagració de Sant Serni de Tavèrnoles

L’objectiu d’aquest article és l’estudi dels dos frontals romànics que van decorar consecutivament el presbiteri de l’església monàstica de Sant Sadurní de Tavèrnoles. Totes dues taules es relacionen, encara que de maneres diferents, amb l’acta de consagració del temple, un document falsificat però molt interessant que evoca l’especial context històric de l’àrea septentrional del comtat d’Urgell. Aquest context incideix directament en la vida dels mobles: explica la destrucció del primer, l’any 1092, i condiciona la creació i el contingut iconogràfic del segon, elaborat probablement durant el tercer quart del segle XII.

La batalla de Baltarga en el joc de la política comtal del segle X: la mort d’Ermengol d’Osona i la successió del comtat d’Urgell
Authors: Vergés Pons Oliver
Published: December 2018

La mort del comte Ermengol d’Osona a la batalla de Baltarga (c. 940) ha estat interpretada de dues maneres totalment oposades. Per a alguns, aquesta batalla va consistir en una topada entre catalans i nòmades hongaresos, mentre que per a d’altres fou un enfrontament entre les principals cases comtals catalanes. En aquest article abordarem la principal historiografia sobre el tema i situarem l’enfrontament de Baltarga al centre del joc de la política comtal catalana de mitjan segle X, rebutjant així les tesis que parlen d’un xoc contra hordes hongareses. Des del primer terç de la desena centúria diverses tensions van enfrontar les cases comtals de Barcelona i Cerdanya, unes tensions que van derivar en un enfrontament armat a la dècada del 940 per dirimir la successió del comtat d’Urgell i l’hegemonia als comtats catalans entre els fills i néts de Guifré el Pelós.

Authors: Utrilla Miranda Pilar , Laborda Lorente Rafael
Published: December 2018

La cueva de Chaves se sitúa en el Prepirineo central, en la provincia de Huesca. Es uno de los yacimientos neolíticos más importantes del noreste de la Península Ibérica, presentando también potentes ocupaciones durante el Solutrense Superior y el Magdaleniense Superior/Final (MSF). Los trabajos arqueológicos en la cavidad comenzaron en 1975 y continuaron hasta la destrucción del yacimiento, en 2007. Mostramos aquí una síntesis de todos los trabajos relativos a cada una de las fases de este yacimiento. Gracias al amplio espacio excavado sugerimos diferentes áreas de actividad dentro de la cavidad. Por último, estudiamos los posibles contactos y movilidad de los diferentes pobladores a lo largo del tiempo tanto en el ámbito pirenaico como en todo el Mediterráneo occidental.
El ámbar de la Cueva de los Cuarenta (Priego de Córdoba, Córdoba)
Authors: Murillo-Barroso Mercedes , Martínez-Sánchez Rafael M. , Vera-Rodríguez Juan Carlos
Published: December 2018

La presencia de objetos exóticos en contextos arqueológicos y los intercambios a larga distancia que estos implican es uno de los temas que despierta más interés en la discusión arqueológica. En este artículo presentamos el estudio de una cuenta o colgante hallado en contextos neolíticos de la Cueva de los Cuarenta (Priego de Córdoba). Se trata del único elemento de adorno presente en la cueva, en la que se ha documentado un número mínimo de 41 inhumaciones datadas a lo largo del IV milenio cal ANE. Se presenta la información contextual del hallazgo así como su caracterización arqueométrica mediante Espectroscopía de Infrarrojos por Transformada de Fourier (FTIR). El análisis de la pieza muestra que se trata de una cuenta de ámbar realizada con material foráneo, similar al empleado en las producciones de ámbar posteriores como las de Valencina de la Concepción (Sevilla). Al igual que en estos casos, se propone la procedencia exógena de la materia prima empleada, siendo Sicilia el origen más plausible a día de hoy, lo cual contribuirá al debate sobre las implicaciones que estos materiales foráneos pudieron tener en las sociedades prehistóricas peninsulares.
Are Lek Disturbance Buffers Equitable for All Gunnison Sage-Grouse Populations?
Authors: Ouren Douglas S. , Cade Brian S. , Holsinger Kenneth W. , Siders Melissa S.
Published: December 2018

Lek disturbance buffers can be used to identify areas that provide important seasonal habitat for Gunnison sage grouse Centrocercus minimus (hereafter GUSG), a species with declining or vulnerable populations across their range. Lek disturbance buffers define areas around leks where anthropogenic disturbance is not permitted and have been considered for potential conservation strategies across GUSG habitat. Currently there is minimal information available on the effectiveness of the size of defined lek disturbance buffers. This study focused on two GUSG populations, the smaller Crawford population and a segment of the larger Gunnison Basin population. We utilized global positioning system location data on GUSG to evaluate seasonal use within three lek disturbance buffers, then compared and contrasted results between the two populations. The Crawford GUSG population showed increased movements from breeding season to late brood-rearing season and in winter returned to a usage pattern similar to the breeding season. Comparatively, the western Gunnison Basin GUSG population showed considerable movement throughout the entire year. In addition to these differences, we noted remarkable differences in distance between active leks, home range size, and total daily distance traveled between Crawford and western Gunnison Basin populations. Lek disturbance buffers created using the standard protocol provided varying protection depending on the distance between leks and number of leks. In small populations, the disturbance buffers overlapped each other, thus producing a smaller total lek disturbance buffer area. In addition to adding to the general body of knowledge of a little-studied species, our study had two important findings: 1) the use of empirical cumulative distribution demonstrated considerable differences in lek disturbance buffer use between the Crawford and the western Gunnison Basin populations, and 2) lek disturbance buffers did not provide equal protection for all populations on the basis of their current definition and derivation. We anticipate that land managers will find our results useful and informative when developing land management plans for the conservation of GUSG. Our analysis showed that the variability between populations and species is important for managers to consider when developing conservation strategies, especially for small populations.

Published: December 2018

botânica pode envolver diversos erros e acarretar prejuízos ao manejo florestal. Um erro comum decorre da variação dos nomes populares, que apresentam peculiaridades regionais e podem ser atribuídos a diversas espécies simultaneamente. Este estudo tem como objetivos analisar a riqueza de espécies madeireiras exploradas na Amazônia brasileira e verificar as variações regionais dos nomes populares das principais espécies, visando identificar padrões e casos de fidelidade. Para isso, foram consultadas informações de espécies comerciais atualmente exploradas e passíveis de exploração em 10 planos de manejo florestal sustentável em diferentes categorias e regiões da Amazônia brasileira. As análises evidenciaram elevada riqueza de espécies comerciais, com baixa similaridade entre as espécies, indicando particularidades locais quanto às espécies de interesse. Os nomes populares apresentaram ampla variação, com duas tendências distintas: utilização de um mesmo nome popular para diversas espécies e utilização de diversos nomes populares para uma única espécie. Foram detectados casos de fidelidade para os nomes populares das principais espécies madeireiras. No entanto, os nomes populares apresentam forte relação com gêneros e famílias botânicas, podendo variar intensamente quando a análise requer identificação em nível de espécie.
Listen Up! Using Podcasts in STEM Courses to Improve Engagement and Facilitate Review
Authors: Laidlaw Kaitlin E. W.
Published: December 2018

This workshop focuses on how to integrate podcasts into science-based courses (e.g., chemistry, psychology). To some students, science-based courses can be perceived as ‘dry’ and difficult to engage with at a level that facilitates retention. Given that engrossing, high-quality teaching is cited as inspiring course enjoyment and leading students to further pursue STEM education (e.g., Horowitz, 2009), lecturers are often looking for ways to increase student interest. More than this, it is the hope of many educators that more enjoyable coursework will lead to better retention and understanding of the material (e.g., Kuh et al., 2008). As a news and entertainment vehicle, podcasts have continued to grow in popularity over the past decade or more. However, the efficacy of using podcasts within educational settings has been mixed (e.g., Daniel & Woody, 2010; Lee & Chan, 2007). This workshop will introduce podcasts as a learning medium and describe ways in which they can be used to effectively complement traditional teaching approaches, either as an enhancement to the course, or as a resource for student review. Attendees will be introduced to several ready-made STEM podcast resources and engage in discussions on how to develop new content that is effective, both logistically and pedagogically.
Community Learning: A Public Humanities Approach to Teaching
Authors: Lee Nahmi
Published: December 2018

This workshop explores how teaching within the humanities is affected, challenged, or improved by public outreach. This question arises from growing concerns that the humanities has become disconnected from the general public or incoherent outside of a post-secondary institutional setting. Research suggests that in addition to the demands of their own research, scholars in the humanities are facing the added pressures of “policy-makers [who] are increasingly demanding that academics justify themselves in terms of the returns that result from investing in their scholarly domains” (Benneworth, 2015, p. 4). These concerns inform the public humanities movement which seeks to foster relations between scholars and their local communities in an effort to champion civic engagement/learning and accessible scholarship. The goal of this workshop is to consider in detail how teaching practices in the humanities might benefit from such community outreach, as well as to support and offer resources to instructors looking for new ways to engage students in this way. The workshop introduces participants to the public humanities movement, initiates debate on the relationship between humanities teaching and public outreach, and suggests strategies and resources for instructors to connect with local communities and outreach programs.
Flipped Classrooms: An Introduction for Coaching Candidates in Higher Education
Authors: Clutterbuck Ryan
Published: December 2018

Former UCLA Bruins head basketball coach and 10-time national champion John Wooden is arguably the most revered coach in any sport and in any time. Yet, in his own words, he suggested “I’m no wizard, I am a teacher” (Gallimore, 2006, np), and that he learned to coach by applying what he learned as a high school English teacher (Gallimore, 2006). Similarly, Côté and Gilbert’s (2009) conceptual model of coaching identifies categories of knowledge coaches need, including professional knowledge as “declarative knowledge in the sport sciences, sport-specific knowledge, and pedagogical knowledge with accompanying procedural knowledge” (p. 310). Thus, inspired by Coach Wooden, and following Côté and Gilbert (2009), the purpose of this workshop is to enhance coaches’ pedagogical knowledge by introducing coaching candidates at post-secondary institutions to the flipped classroom (FC) approach. In higher education, FCs have been shown to improve student engagement, motivation, satisfaction, and creativity (Al-Zahrani, 2015; Chen, Lui, & Martinelli, 2017; Herreid & Schiller, 2013; Rotellar & Cain, 2016) – outcomes that may be especially important to coaches. Participants in this workshop will learn about FCs in an interactive 90-minute session, collaborating with peers to address issues that are relevant to their teams, and incorporating FC principles to improve their teaching and enhance student-athlete satisfaction.
La situación de la mujer en los estudios de filosofía. Un análisis basado en indicadores
Authors: Torres González Obdulia
Published: December 2018

El artículo presenta un análisis, basado en indicadores, de la situación de la mujer en los estudios de filosofía y la carrera académica posterior. Aunque filosofía es agrupada, a efectos estadísticos, con las disciplinas de humanidades, que es un campo tradicionalmente considerado femenino, el trabajo muestra que los estudios de filosofía son un ámbito de conocimiento sumamente masculinizado. Los datos revelan: (1) que los estudiantes varones sobrepasan a las mujeres en 28 puntos porcentuales, (2) un porcentaje de profesorado femenino que apenas sobrepasa el 25% y (3) un techo de cristal reforzado con un 12% de catedráticas, frente al 21% de promedio en la universidad. En el artículo, se profundiza en el análisis de la segregación horizontal y vertical y se analiza la hipótesis FAB (field-specific ability belief). Esta hipótesis postula que las mujeres están infrarrepresentadas en aquellos campos, cuyos profesionales creen que el talento innato es el principal requerimiento para el éxito en su disciplina. El trabajo se enmarca en un proyecto más amplio, que busca mostrar que los agregados estadísticos usados en los estudios de segregación horizontal no son homogéneos, en lo que respecta a la presencia de la mujer, lo que en última instancia repercute en la efectividad de las medidas políticas que se toman.
Modal particles and sentence type restrictions: A construction grammar perspective
Authors: Alm Maria , Behr Janina , Fischer Kerstin
Published: December 2018

The problem addressed in this study is the sentence type restrictions of modal particles. In the literature on modal particles, it is often noted that these items cannot occur freely in all kinds of sentence types, but are restricted to certain grammatical host structures. In this article, we first discuss previous work on the semantic, formal and functional factors that determine the usage of modal particles in different grammatical configurations. The results of this discussion show that a fine-grained representation on several different levels of both modal particles and their grammatical environments is necessary to account for the usage restrictions, which is why we turn to a construction grammatical description. In particular, we suggest that the sentence type restrictions of modal particles are the result of a complex interaction between the individual modal particle on the one hand and specific grammatical constructions on the other hand. In this paper, we focus on constructions of the kind encoding particular speech act orientations, namely sentence type constructions. We explore this interaction from a construction grammatical perspective.

This study was conducted aiming at measuring the performance and behavior of beef cattle surgically castrated, immunocastrated or non-castrated, finished at 18 months old in Aruana pasture and with energy supplementation. Thirty-nine male bovines with an initial average body weight and age of 284.1 ± 31.4 kg and 14 months old, respectively, were used. The bromatological composition analysis and productive parameters of the pasture did not differ between treatments. The performance of young cattle was not changed by the sexual condition. When evaluating the agonistic behavior, the non-castrated bovine presented a higher number of activities, such as threats and fights, in relation to those immunocastrated. The time spent on the feeder by non-castrated young cattle (56.20 minutes) was higher than that observed for surgically castrated or immunocastrated (41.43 and 32.38 minutes, respectively). The combination between the correct management of Aruana pasture and use of supplementation showed to be promising for finishing bovines. Both surgically castrated and immunocastrated steers demonstrated to be equivalents in the performed evaluations. Therefore, if the farmer chooses castration, the use of immunocastration is suggested. This practice is less invasive, preserves animal welfare more than surgical castration, and has a lower cost.

Feeding goats with calcium salts of fatty acids (CSFA) can supply ruminants with lipids, with minimal effects on ruminal fermentation and fiber digestibility. However, there is a shortage of information on the effect of CSFA on characteristics of rumen fermentation in grassland goats. Thus, the present study aimed to assess the addition of CSFA to concentrate on the parameters of rumen fermentation of grazing goats. Five rumen cannulated goats were distributed in a Latin square 5x5 design (treatments: 0%, 1.5%, 3.0%, 4.5% and 6.0% CSFA. The pH, ammonia N and volatile fatty acids (VFA) content were analyzed in the ruminal fluid at 0, 2, 4, 6 and 8 hours after concentrate supplementation. The pH and ammonia N concentration showed a linear effect with the addition of CSFA. There was no effect observed for the VFA molar concentration after grazing goats were fed with the experimental diet. In conclusion, further research is needed to investigate the addition of CSFA to goat diets because there is evidence that CSFA increases ruminal pH and decreases excess ruminal ammonia without changing the VFA concentration in the rumen fluid.

This study aimed to assess the performance, carcass traits, and non-carcass components of feedlot finished Texel crossbred lambs from different residual feed intake classes (RFI). Forty-seven uncastrated male Texel crossbred lambs (¾ Texel + ¼ Pantaneira) tested here were 4-month-old with an initial weight of 29.9 ± 5.5 kg. The lambs were confined for 70 days for individual dry matter intake (DMI) and average daily gain (ADG) assessment. The diet containing corn silage was provided as roughage, while the concentrate consisted of corn grain, soybean meal, urea, and mineral mixture with a 40:60 roughage to concentrate ratio and 76.34% total digestible nutrients (TDN). After confinement for 70 days, the lambs were slaughtered to assess carcass traits and non-carcass components. Based on the RFI, lambs were divided into three classes according to the standard deviation (sd): Positive RFI (inefficient, 0.5 above the mean), Negative RFI (efficient, 0.5 below the mean), and Medium RFI (intermediate). Classes with Negative (efficient) and Positive RFI (inefficient) showed no differences in ADG (0.321 vs 0.306 kg; P > 0.05). Dry matter intake (g d-1), and percentage of body weight (BW) differed significantly between the RFI classes (P < 0.05). Compared to lambs in the inefficient class, those in the efficient class (Negative RFI) showed a 9% reduction in DMI and had the same ADG. The lambs in either Positive or Negative RFI classes showed no weight differences between non-carcass components (P > 0.05). The RFI classes showed no differences in shrunk body weight, hot carcass weight, hot dressing, and weight of commercial cuts (P > 0.05). They showed no differences in neck, shoulder + shank, loin, rack, flank steak, rack cap off, and leg weights (P > 0.05). Our results indicate that improvement in feed efficiency, as a function of the RFI index, does not compromise performance and carcass traits of Texel crossbred lambs.
