Imbalanced Learning for RR Lyrae Stars Based on SDSS and GALEX Databases
Authors: Zhang Jingyi , Zhang Yanxia , Zhao Yongheng
Published: February 2018

We apply machine learning and Convex-Hull algorithms to separate RR Lyrae stars from other stars like main-sequence stars, white dwarf stars, carbon stars, CVs, and carbon-lines stars, based on the Sloan Digital Sky Survey and Galaxy Evolution Explorer (GALEX). In low-dimensional spaces, the Convex-Hull algorithm is applied to select RR Lyrae stars. Given different input patterns of (u − g, g − r), (g − r, r − i), (r − i, i − z), (u − g, g − r, r − i), (g − r, r − i, i − z), (u − g, g − r, i − z), and (u − g, r − i, i − z), different convex hulls can be built for RR Lyrae stars. Comparing the performance of different input patterns, u − g, g − r, i − z is the best input pattern. For this input pattern, the efficiency (the fraction of true RR Lyrae stars in the predicted RR Lyrae sample) is 4.2% with a completeness (the fraction of recovered RR Lyrae stars in the whole RR Lyrae sample) of 100%, increases to 9.9% with 97% completeness and to 16.1% with 53% completeness by removing some outliers. In high-dimensional spaces, machine learning algorithms are used with input patterns (u − g, g − r, r − i, i − z), (u − g, g − r, r − i, i − z, r), (NUV − u, u − g, g − r, r − i, i − z), and (NUV − u, u − g, g − r, r − i, i − z, r). RR Lyrae stars, which belong to the class of interest in our paper, are rare compared to other stars. For the highly imbalanced data, cost-sensitive Support Vector Machine, cost-sensitive Random Forest, and Fast Boxes is used. The results show that information from GALEX is helpful for identifying RR Lyrae stars, and Fast Boxes is the best performer on the skewed data in our case.
New Constraints on Gliese 876—Exemplar of Mean-motion Resonance

Published: February 2018

Gliese 876 harbors one of the most dynamically rich and well-studied exoplanetary systems. The nearby M4V dwarf hosts four known planets, the outer three of which are trapped in a Laplace mean-motion resonance. A thorough characterization of the complex resonant perturbations exhibited by the orbiting planets, and the chaotic dynamics therein, is key to a complete picture of the system’s formation and evolutionary history. Here we present a reanalysis of the system using 6 yr of new radial velocity (RV) data from four instruments. These new data augment and more than double the size of the decades-long collection of existing velocity measurements. We provide updated estimates of the system parameters by employing a computationally efficient Wisdom–Holman N-body symplectic integrator, coupled with a Gaussian process (GP) regression model to account for correlated stellar noise. Experiments with synthetic RV data show that the dynamical characterization of the system can differ depending on whether a white-noise or correlated-noise model is adopted. Despite there being a region of stability for an additional planet in the resonant chain, we find no evidence for one. Our new parameter estimates place the system even deeper into resonance than previously thought and suggest that the system might be in a low-energy, quasi-regular double apsidal corotation resonance. This result and others will be used in a subsequent study on the primordial migration processes responsible for the formation of the resonant chain.
The Effects of Environment on the Evolution of the Galaxy Stellar Mass Function

We study the effects of galaxy environment on the evolution of the stellar mass function (SMF) over 0.2 < z < 2.0 using the FourStar Galaxy Evolution (ZFOURGE) Survey and NEWFIRM Medium-Band Survey (NMBS) down to the stellar mass completeness limit,

(9.5) at z = 1.0 (2.0). We compare the SMFs for quiescent and star-forming galaxies in the highest and lowest environments using a density estimator based on the distance to the galaxies’ third-nearest neighbors. For star-forming galaxies, at all redshifts there are only minor differences with environment in the shape of the SMF. For quiescent galaxies, the SMF in the lowest densities shows no evolution with redshift other than an overall increase in number density (ϕ*) with time. This suggests that the stellar mass dependence of quenching in relatively isolated galaxies both is universal and does not evolve strongly. While at

, the SMF of quiescent galaxies is indistinguishable in the highest and lowest densities, at lower redshifts, it shows a rapidly increasing number density of lower-mass galaxies,

, in the highest-density environments. We argue that this evolution can account for all the redshift evolution in the shape of the total quiescent galaxy SMF. This evolution in the quiescent galaxy SMF at higher redshift (z > 1) requires an environmental quenching efficiency that decreases with decreasing stellar mass at 0.5 < z < 1.5 or it would overproduce the number of lower-mass quiescent galaxies in denser environments. This requires a dominant environmental process such as starvation combined with rapid gas depletion and ejection at z > 0.5–1.0 for galaxies in our mass range. The efficiency of this process decreases with redshift, allowing other processes (such as galaxy interactions and ram-pressure stripping) to become more important at later times, z < 0.5.
Donner la parole aux interprètes : le mythe de la neutralité et autres facteurs contextuels pouvant nuire à la performance
Authors: René de Cotret François , Ošlejšková Eva , Tamouro Soumya , Leanza Yvan
Published: February 2018

Tel que le note Hsieh (2016), les facteurs contextuels pouvant avoir une influence sur la performance de l’interprète n’ont été que peu étudiés en santé, ce que notre étude cible. Méthode : Nous avons effectué une analyse thématique des propos de 24 interprètes de Montréal (Canada), divisés en quatre groupes de discussion. Résultats : Leur discours gravite autour de 11 facteurs contextuels nuisant à la performance, répartis en trois thèmes : consultation interprétée, principes éthiques et conditions de travail. Discussion : La majorité des 11 facteurs touche à la qualité de la relation interprète-praticien, minée entre autres par un manque de temps multiforme entourant la consultation et l’idée voulant que les praticiens recherchent en l’interprète un conduit. Le domaine nécessite un réaménagement conceptuel, en particulier à propos de la neutralité de l’interprète, qui n’est pas un mythe dommageable tel que l’avance Angelelli (2004), mais un puissant vecteur relationnel.

El Venerable Arnaldo Amalarico (h. 1196-1225): idea y realidad de un cisterciense entre dos cruzadas
Authors: Alvira Cabrer Martín
Published: February 2018

Tras ser elegido por méritos propios abad general de la poderosa Orden del Císter, el catalán Arnaldo Amalarico (1225) dirigió como legado papal la lucha pacífica y luego violenta de la Iglesia contra el catarismo occitano. Su liderazgo no sólo marcó los primeros destinos de la Cruzada Albigense (1208-1214) sino que también tuvo reflejo durante la Cruzada de Las Navas de Tolosa (1212), a la que se unió tras ser elegido arzobispo de Narbona. Mientras, en ambas empresas, el venerable Arnaldo mostró lo mejor de sus cualidades de hombre de acción, en la primera encarnó lo peor de la violencia y el fanatismo que definieron la guerra santa contra los señores occitanos acusados de herejía. Decidida esta cruzada en la batalla de Muret (1213), Arnaldo perdió su anterior protagonismo, desprestigiándose en una pugna feudal por el ducado de Narbona debida a ambiciones señoriales y, quizá, familiares. Personalidad excepcional, el cisterciense Arnaldo Amalarico es, sin duda, uno de los principales protagonistas del Occidente medieval de principios del siglo XIII.

La persecución religiosa de 1936-1939: estado de la cuestión y propuestas historiográficas
Authors: Martín Rubio Ángel David
Published: February 2018

Uno de los factores ideológicos más importantes de la represión desencadenada en la zona republicana durante la Guerra Civil, fue la persecución religiosa. Esto explica que desde los primeros momentos hayan aparecido numerosas publicaciones alusivas al fenómeno. Pero carecemos aún de una valoración global de lo que supuso la persecución religiosa desencadenada en España desde 1931: no poseemos un catálogo actualizado de los sacerdotes y religiosos asesinados y no podemos señalar un balance de la persecución en cada zona. En el presente trabajo se expone la trayectoria seguida por esta producción bibliográfica y se plantea la necesidad de emplear nuevas fuentes y de aplicar a los datos disponibles una metodología que permita el paso de lo biográfico a lo cuantitativo. Se trata del avance metodológico de un estudio en proceso de realización.

El fantasma del Priscilianismo, Apringio de Beja y el Apocalipsis
Authors: Barcala Andrés
Published: February 2018

Los escritos joaneos, y especialmente el Apocalipsis, tardaron un tiempo llamativo en ser utilizados por los escritores cristianos y en ser admitidos en el canon de las Escrituras. En España la resistencia a estudiar su texto y a utilizarlo duró todavía más que en el resto del Occidente cristiano. Este hecho se debió, sobre todo, al temor del priscilianismo y al estereotipo creado en tomo a él por los principales escritores y heresiólogos del siglo V, que lo consideraron como la herejía "nacional" hispana, lo vincularon con un gnosticismo sin vigencia hacía más de dos siglos y con la aplicación a la exegesis de la ciencia del cálculo numérico. Apringio de Beja intentó introducir nuevas perspectivas, escribiendo un comentario seguido al Apocalipsis, para lo que disponía de escasos precedentes.
Iglesia e Inquisición en la España Norteafricana: Orán y Mazalquivir a fines del reinado de Felipe II
Authors: Alonso Acero Beatriz
Published: February 2018

La presencia de España en Oran y Mazalquivir desde comienzos del siglo XVI, remite a las tierras del otro lado del Estrecho la polémica sobre las relaciones entre Cristiandad, judaísmo e Islam. La recuperación de estos enclaves para el Cristianismo provoca la necesidad de reorganizar una Iglesia, tanto en lo que se refiere a la edificación de centros dedicados al culto, como a la implantación de un estamento eclesiástico que cumpla las importantes misiones que tiene encomendadas en estos presidios, que mantienen continuos contactos con Islam y judaísmo. La fragilidad de la frontera que separa a Cristiandad e Islam en este contexto tan específico, estimula la actuación del Santo Oficio de Murcia, el encargado de la jurisdicción inquisitorial de Oran y Mazalquivir, persiguiendo con especial fruición a los sospechosos de islamizar.

Conversos musulmanes en la Berbería cristiana: el infortunio de la Cruzada Pacífica contra el Islam
Authors: Alonso Acero Beatriz
Published: February 2018

La labor evangelizadora respecto a los musulmanes realizada por la Iglesia cristiana en los enclaves conquistados por Castilla en Berbería en los años finales del siglo XV y primeros del XVI, cruzada pacífica contra el infiel, parte de unos presupuestos previos de éxito cuya falsedad se encargará de demostrar la propia realidad. Pronto se hace patente la dificultad de llevar a buen término esta obra misionera. No existe un proyecto previo bien definido y trazado, lo que no favorece que lleguen a estas latitudes más eclesiásticos y mejor preparados. Además, la precariedad que padecen los presidios cristianos a los que se trasladan las órdenes religiosas encargadas del adoctrinamiento de estos musulmanes, tanto esclavos como libres, perjudica aún más la adecuada realización de esta tarea.

La aprobación civil del Colegio de Misioneros del Padre Claret: 1859 y 1867, conforme al artículo 29 del Concordato de 1851
Authors: Sastre Santos Eutimio
Published: February 2018

El artículo 29 del Concordato entre España y la Santa Sede del 1851 fue uno de los más controvertidos. Durante los años de vigencia del Concordato, que pueden extenderse hasta el 1953, no se fijó su clara interpretación y aplicación. El presente trabajo muestra la interpretación que de él hizo el gobierno liberal de Isabel II. En conformidad con el dicho artículo 29, la unión liberal de O´Donnell aprobó en 1859 los Estatutos del Colegio de Misioneros del Padre Claret, y el gobierno de Narváez en 1867 concedió a sus miembros la exención de quintas; de ambos actos necesitaba el Colegio de Misioneros para afirmarse. La investigación realizada estriba sobre los papeles del archivo del Ministerio de Justicia. Se añade un apéndice bibliográfico sobre el Concordato del 1851 y su artículo 29.
Los caracteres de la polémica cristiana contra el Islam entre Basilea y Trento
Authors: Alonso Acero Beatriz
Published: February 2018

El artículo aborda los rasgos fundamentales de la polémica cristiana contra el Islam en la segunda mitad del siglo XV y en la primera del XVI, atendiendo a la doble perspectiva en que se puede dividir su estudio. Por un lado, la postura de enfrentamiento entre las dos religiones, basada en la concepción cristiana del Islam como doctrina falsa desde su revelación y cargada de errores en la práctica. Por otro, la actitud más conciliadora, que también reconoce al cristianismo como única doctrina verdadera pero busca una aproximación a los musulmanes con intención evangelizadora. Dentro de cada postura se atiende a sus autores más representativos y a la plasmación práctica de los postulados teóricos, en especial en la España de comienzos del siglo XVI.
La Orden del Hospital y la recepción de los bienes templarios en la Península Ibérica
Authors: Barquero Goñi Carlos
Published: February 2018

Cuando el Temple fue disuelto en el Concilio de Vienne en 1312, el papa Clemente V incorporó los bienes templarios a los hospitalarios. Sin embargo, los reyes ibéricos se opusieron a este crecimiento del Hospital. Preferían fundar nuevas Órdenes Militares en sus reinos con las posesiones templarías. El pontificado tuvo que negociar con cada monarquía peninsular el destino de estas propiedades. Al final, los hospitalarios no recibieron nada en Portugal y muy poco en Castilla. Perdieron casi todos sus bienes en Valencia, pero las posesiones templarías en Navarra, Mallorca, Aragón y Cataluña fueron efectivamente transferidas a la Orden del Hospital.

Le projet Vaccins Méningite a permis à des millions d’Africains de disposer d’un vaccin peu coûteux, le MenAfriVac®, grâce à un transfert de technologie. Les récits de la biomédecine en ont fait une histoire à succès, un mythe sociotechnique anonyme et collectif dans lequel le MenAfriVac® revêt une efficacité magique. Les promoteurs du vaccin ont choisi la rhétorique de l’élimination de la méningite par un vaccin, occultant un contexte épidémiologique plus complexe, notamment la persistance d’épidémies, docu-mentées et dues à des sérogroupes autres que ceux ciblés par le MenAfriVac®.

Ensuite, la contribution souligne que le MenAfriVac® est révélateur d’un type de « solution globale » privilégiant un émiettement des priorités et une visée à court terme de la santé publique.
The Impact of Earnings Quality on the Stock Returns of Listed Manufacturing Companies in the Colombo Stock Exchange
Authors: Wijesinghe M. R. P. , Kehelwalatenna Sampath
Published: February 2018

The earnings of a company is a very important indicator of firm performance, since it communicates information about the value creating ability of the company to its stakeholders. It is also considered a determinant of the stock market performance of the company. However, the possibility for managers to manipulate the true earnings of a company erodes the importance of using recorded earnings information in financial statements for decision making. Earnings quality could be measured using different proxy measures, varying from traditional accrual based measures to recent real earnings based measures. The earnings quality literature contains a plethora of evidence on the impact of earnings quality measured through accrual based measures on stock returns but it does not have as much evidence on the same impact where earnings quality is measured through real earnings. Further, the literature does not have a comparative study on how different earnings quality measures provide different results in the estimation of the impact of earnings quality on stock returns. Empirical evidence on the same relationship using data from the Sri Lankan context is virtually absent in the extant literature. In this milieu, the present study examines the impact of earnings quality measured through both accrual based measures and real earnings measures on stock returns of listed manufacturing companies in Sri Lanka during the period of 2010 to 2015. The findings of the study reveal that there is no significant positive impact of earnings quality on stock returns of the firms selected for the study. This suggests that earnings quality information of the selected firms fails to win investor trust when investors make their decisions. Perhaps this may be due to the fact that earnings manipulation is evident in the Sri Lankan context. Further, the study reveals that there is no inconsistency when measuring earnings quality through competing measurements.
Two variants of the Froidure–Pin Algorithm for finite semigroups
Authors: Jonušas Julius , Mitchell James D. , Pfeiffer Markus
Published: February 2018

In this paper, we present two algorithms based on the Froidure-Pin Algorithm for computing the structure of a finite semigroup from a generating set. As was the case with the original algorithm of Froidure and Pin, the algorithms presented here produce the left and right Cayley graphs, a confluent terminating rewriting system, and a reduced word of the rewriting system for every element of the semigroup.

If

U

is any semigroup, and

A

is a subset of

U

, then we denote by

\langle A\rangle

the least subsemigroup of

U

containing

A

. If

B

is any other subset of

U

, then, roughly speaking, the first algorithm we present describes how to use any information about

\langle A\rangle

, that has been found using the Froidure-Pin Algorithm, to compute the semigroup

\langle A\cup B\rangle

. More precisely, we describe the data structure for a finite semigroup

S

given by Froidure and Pin, and how to obtain such a data structure for

\langle A\cup B\rangle

from that for

\langle A\rangle

. The second algorithm is a lock-free concurrent version of the Froidure-Pin Algorithm.
Commutativity theorems for groups and semigroups

In this note we prove a selection of commutativity theorems for various classes of semigroups. For instance, if in a separative or completely regular semigroup

S

we have

x^p y^p = y^p x^p

and

x^q y^q = y^q x^q

for all

x,y\in S

where

p

and

q

are relatively prime, then

S

is commutative. In a separative or inverse semigroup

S

, if there exist three consecutive integers

i

such that

(xy)^i = x^i y^i

for all

x,y\in S

, then

S

is commutative. Finally, if

S

is a separative or inverse semigroup satisfying

(xy)^3=x^3y^3

for all

x,y\in S

, and if the cubing map

x\mapsto x^3

is injective, then

S

is commutative.
Student Developed Knowledge Portfolios from a Soil Fertility Course
Authors: Sindelar Meghan , Mamo Martha , Wingeyer Ana
Published: February 2018

Core Ideas

Portfolios are useful for students to organize and reflect upon course content.

Portfolios can serve as a knowledge toolbox that students can use in future work.

The portfolio assignment used in a soil fertility course is described.

Students who have completed the Soil Nutrient Relationships course at the University of Nebraska–Lincoln often contact instructors once they have begun full‐time work, seeking reminders of specific concepts. These students either did not take or keep detailed notes during the course. To assist students, instructors have developed a portfolio requirement for the course. One important learning objective from each recitation exercise was summarized as deliverable knowledge in the student's portfolio. Feedback was then provided on portfolio components each week with resubmission encouraged, so that students leave with accurate information in their own words. The objective of this article is to summarize the details of the portfolio assignment used in Soil Nutrient Relationships to assist other instructors in developing student assignments and assessments. Following completion of the knowledge portfolio, students were surveyed with more than 75% response rate in both the 2016 and 2017 semesters. More than 44% of respondents agreed that they thought they would use the portfolio in their future work, and more than 15% of respondents agreed that the portfolio would be the most important component of class toward their future work.
Viewing Disability in Medieval Spanish Texts
Authors: Scarborough Connie
Published: February 2018

This book is one of the first to examine medieval Spanish canonical works for their portrayals of disability in relationship to theological teachings, legal precepts, and medical knowledge. Connie L. Scarborough shows that physical impairments were seen differently through each lens. Theology at times taught that the disabled were "marked by God," their sins rendered on their bodies; at other times, they were viewed as important objects of Christian charity. The disabled often suffered legal restrictions, allowing them to be viewed with other distinctive groups, such as the ill or the poor. And from a medical point of view, a miraculous cure could be seen as evidence of divine intervention. This book explores all these perspectives through medieval Spain's miracle narratives, hagiographies, didactic tales, and epic poetry.
Summertime fine particulate nitrate pollution in the North China Plain: Increasing
trends, formation mechanisms, and implications for control policy
Authors: Wen Liang , Xue Likun , Wang Xinfeng , Xu Caihong , Chen Tianshu , Yang Lingxiao , Wang Tao , Wang Wenxing
Published: February 2018

Abstract. Nitrate aerosol composes a significant fraction of fine particles and plays a key role in regional air quality and climate. To obtain a holistic understanding of the nitrate pollution and its formation mechanisms over the North China Plain (NCP) – the most industrialized and polluted region in northern China, intensive field observations were conducted at three sites during summertime in 2014–2015. The measurement sites include the downtown and downwind of Ji'nan, the capital city of Shandong Province, as well as the peak of NCP – Mt. Tai (1534 m a.s.l.), and hence cover representative urban, rural and remote areas of the region. Elevated nitrate concentrations were observed at all three sites despite distinct temporal and spatial variations. The nitrate / PM2.5 and nitrate / sulfate ratios have significantly increased in Ji'nan (2005–2015) and at Mt. Tai (from 2007 to 2014), indicating the worsening situation of regional nitrate pollution. A multi-phase chemical box model (RACM/CAPRAM) was deployed and constrained by observations to elucidate the nitrate formation mechanisms. The principal formation route is the partitioning of gaseous HNO3 to aerosol phase at daytime, whilst the nocturnal nitrate formation is dominated by the heterogeneous hydrolysis of N2O5. The daytime nitrate production in the NCP region is mainly limited by the availability of NO2 and to a lesser extent O3 and NH3, and the nighttime formation is controlled by both NO2 and O3. NH3 prompts significantly the nitrate formation at daytime but plays a slightly negative role in the nighttime. Our analyses suggest that controlling NOx and O3 is an efficient way at the moment to mitigate nitrate pollution in the NCP region, where NH3 is usually in excess in summer. This study provides observational evidence of rising trend of nitrate aerosol as well as scientific support for formulating effective control strategies for regional haze in China.
The geomagnetic coast effect at two 80° S stations in Antarctica, observed in the ULF range
Authors: Regi Mauro , De Lauretis Marcello , Francia Patrizia , Lepidi Stefania , Piancatelli Andrea , Urbini Stefano
Published: February 2018

Abstract. We examined the coast effect in Antarctica along the 80∘ S magnetic
parallel. We used the geomagnetic field measurements at the two coastal
stations of Mario Zucchelli Station and Scott Base, and, as a reference, at
the inland temporary station Talos Dome, during 18 January–14 March 2008.
Spectral analysis in the Pc5 frequency range (1–7 mHz) revealed
large differences between coastal and inland stations, such as higher
spectral power levels in the vertical component and higher coherence between
horizontal and vertical components at coastal stations. Using the
interstation method on selected active time intervals, with Talos Dome as a
remote reference station, we found that remote reference induction arrows are
directed almost perpendicularly with respect to their respective coastlines.
Moreover, the single-station analysis shows that at Talos Dome the amplitude
of the induction arrows is much smaller than at coastal stations. These
results clearly indicate that coast effect at a few hundred kilometers from
the coastline is relatively small. The coast effect on polarization
parameters was examined, for a Pc5 event that occurred on 11 March 2008. The
results evidenced that the azimuthal angle of polarized signals at one of the
coastal stations is largely different with respect to the inland station (by
∼ 110∘), while the polarization ratio and ellipticity attain
comparable values. We proposed a correction method of the polarization
parameters, which operates directly in the frequency domain, obtaining
comparable azimuthal angles at coastal and inland stations. Keywords. Ionosphere (wave propagation) – magnetospheric physics (polar cap phenomena; storms and substorms)
Crustal heat production and estimate of terrestrial heat flow in central East Antarctica, with implications for thermal input to the East Antarctic ice sheet
Authors: Goodge John W.
Published: February 2018

Abstract. Terrestrial heat flow is a critical first-order factor governing the thermal condition and, therefore, mechanical stability of Antarctic ice sheets, yet heat flow across Antarctica is poorly known. Previous estimates of terrestrial heat flow in East Antarctica come from inversion of seismic and magnetic geophysical data, by modeling temperature profiles in ice boreholes, and by calculation from heat production values reported for exposed bedrock. Although accurate estimates of surface heat flow are important as an input parameter for ice-sheet growth and stability models, there are no direct measurements of terrestrial heat flow in East Antarctica coupled to either subglacial sediment or bedrock. As has been done with bedrock exposed along coastal margins and in rare inland outcrops, valuable estimates of heat flow in central East Antarctica can be extrapolated from heat production determined by the geochemical composition of glacial rock clasts eroded from the continental interior. In this study, U, Th, and K concentrations in a suite of Proterozoic (1.2–2.0 Ga) granitoids sourced within the Byrd and Nimrod glacial drainages of central East Antarctica indicate average upper crustal heat production (Ho) of about 2.6  ±  1.9 µW m−3. Assuming typical mantle and lower crustal heat flux for stable continental shields, and a length scale for the distribution of heat production in the upper crust, the heat production values determined for individual samples yield estimates of surface heat flow (qo) ranging from 33 to 84 mW m−2 and an average of 48.0  ±  13.6 mW m−2. Estimates of heat production obtained for this suite of glacially sourced granitoids therefore indicate that the interior of the East Antarctic ice sheet is underlain in part by Proterozoic continental lithosphere with an average surface heat flow, providing constraints on both geodynamic history and ice-sheet stability. The ages and geothermal characteristics of the granites indicate that crust in central East Antarctica resembles that in the Proterozoic Arunta and Tennant Creek inliers of Australia but is dissimilar to other areas like the Central Australian Heat Flow Province that are characterized by anomalously high heat flow. Age variation within the sample suite indicates that central East Antarctic lithosphere is heterogeneous, yet the average heat production and heat flow of four age subgroups cluster around the group mean, indicating minor variation in the thermal contribution to the overlying ice sheet from upper crustal heat production. Despite these minor differences, ice-sheet models may favor a geologically realistic input of crustal heat flow represented by the distribution of ages and geothermal characteristics found in these glacial clasts.
A NATUREZA DA FORÇA: NOTAS SOBRE O TEXTO LATINO DE IN PHYSICA II, 1, L. 11-14 DE FILOPONO
Authors: Brás dos Santos Evaniel
Published: February 2018

Este artigo apresenta uma exegese do In Physica II, 1, l. 11-14 de Filipono, texto no qual o autor expõe uma compreensão da noção de força como formadora e diretiva da totalidade dos corpos na medida em que os mantém no ser, conferindo, portanto, unidade e ordenação ao cosmo. Nesse contexto, é possível sustentar que a força vinculada com a locomoção natural dos corpos simples tomados em conjunto, o cosmo, é uma anima mundi. Para tanto, a noção de vida, também presente no In Physica II, 1, l. 11-14, é tomada como chave de leitura, uma vez que por ela tem sentido afirmar que o cosmos possui uma forma, esta que, no limite, é a própria alma do cosmo.

Authors: Subramanian N. , Rajagopal N. , Thirunavukarasu P.
Published: February 2018

In this paper we introduce a new concept for Riesz almost lacunary $\Gamma^{3}$ sequence spaces strong $P-$ convergent to zero with respect to an Musielak-Orlicz function and examine some properties of the resulting sequence spaces. We also introduce and study statistical convergence of Riesz almost lacunary $\Gamma^{3}$ sequence spaces and also some inclusion theorems are discussed.
Tauberian conditions under which statistical convergence follows from statistical summability $(EC)_{n}^1$
Authors: Braha Naim L. , Temaj Ismet

Let $(x_k)$, for $k\in \mathbb{N}\cup \{0\}$  be a sequence of real or complex numbers and set $(EC)_{n}^{1}=\frac{1}{2^n}\sum_{j=0}^{n}{\binom{n}{j}\frac{1}{j+1}\sum_{v=0}^{j}{x_v}},$ $n\in \mathbb{N}\cup \{0\}.$  We present necessary and sufficient conditions, under which $st-\lim_{}{x_k}= L$ follows from $st-\lim_{}{(EC)_{n}^{1}} = L,$ where L is a finite number. If $(x_k)$ is a sequence of real numbers, then these are one-sided Tauberian conditions. If $(x_k)$ is a sequence of complex numbers, then these are two-sided Tauberian conditions.

An Analysis of the Level of Qualitative Efficiency for the Equity Research Reports in the Italian Financial Market
Authors: Fandella Paola
Published: February 2018

Corporate reports issued by various financial intermediaries play a major role in investment decisions. For this reason, it is particularly interesting to understand the accuracy of the forecasts, by carrying out an empirical analysis of the "equity research" system in Italy, identifying structural features, degree of reliability and incidence in the market. The choice of the analysis of the efficiency level information on the Italian market proposes to assess the interest of equity research of a niche market (339 listed companies in 2017) but with characteristics of potential growth such as having been acquired by LSEGroup in 2007, the 6th stock-exchange group at international level for the number of listed companies and the 4th for capitalization.The analysis was carried out on the reports issued on companies belonging to the Ftse Mib stock index during a period of 5 years.It aims to analyse the composition of the equity research system in Italy as well as the analysts' ability to properly evaluate the stocks' fair price, so as to test their degree of reliability and detect possible anomalies in recommendations to the investors.
Myth in the History and Modern World of She People: The Preservation, Transmission and Uses of Epic Stories in the Ethnic Group of South-Eastern China
Authors: Yan Sai
Published: February 2018

This article gives an ethnographic account of the epic tradition of She people in China, noting the dual transmission methods of stories, in which the core of the story is preserved in pictorial depictions within primarily sacred contexts, whilst more flexible oral retellings fit the stories to the daily life of the She in modern China. The article contrasts western views of myth as a feature of a pre-modern way of life which has lost its relevance in the modern world with common understandings of myth in China as factually based and relevant to contemporary life. The article shows how the She deploy their mythic heritage to reinforce their ethnic identity and to pursue material interests within the context of modernizing Chinese state, numerically and politically dominated by the Han majority, and draws upon the work of Claude Levi-Strauss to suggest that myth remains an important component of Chinese modernity.
An Analysis of the Differences Between Praise and Flattery by the Co-operative Principle
Authors: Zhu Changfeng
Published: February 2018

This paper will distinguish praise and flattery based on the Gricean maxims of the Co-operative Principle and the four maxims. Through the comparative studies and typical instances, we found that Praise contains two necessary parts: the facts and their approval or admiring feelings of the addressee. Both of them should be quantity-proper, true, relevant and in a clear way; while flattery sits on opposite ends of a spectrum.
Terrorism in Contemporary Era Narration
Authors: Al Areqi Rashad Mohammed Moqbel
Published: February 2018

Terrorism is the talk of the world. It also occupies a larger part in the media and Islam receives relatively high attention compared to other religions. Islam, Muslims, particularly Arabs, in the eyes of the West, become the source of terrorism that gives the West an opportunity to launch a war against the countries which are accused of terrorism. It is, in fact, a war against radical Islam as they claimed. How do the western politicians, reporters, journalists and writers address terrorism in their official speech or literary works that reflect their vision and understanding of terror/terrorism? The present article addresses Amy Waldman’s The Submission, 2011, John Updike’s Terrorist, 2006, Joel Rosenberg’s The Last Jihad, 2002, and their vision of terrorism, its reasons and the people behind. The article concluded that the western narratives written during the controversial period of the post 9/11. 2001 came deeply influenced by the western media reports and the official statements about 9/11. Such narratives also created, but enrooted Islamophobia and anti- Muslim attitudes in the hearts of the westerners while the western narratives written lately showed more sympathy and rationality towards Muslim characters because the hidden facts of terrorism become exposed. The narratives showed that the western countries exaggerate in their reactions against terrorists/terrorism and the present research concluded that the West has taken precautionary steps to protect its interests and its allies in such countries accused of terrorism. The westerners make use of their domination upon the media to create negative and aggressive attitudes towards Islam/Muslims to blackmail the Islamic countries in the name of war on terrorism, and to secularize/westernize the different aspects of life in such Islamic countries. The narratives showed that war on terrorism is a war on Islam, particularly, radical Islam as claimed.
Peak Trekking of Hierarchy Mountain for the Detection of Cerebral Aneurysm using Modified Hough Circle Transform
Authors: Mitra Jubin , Chandra Abhijit , Halder Tanmay
Published: February 2018

The Circle of Willis is the junction of two carotid arteries and two vertebral arteries that supply the brain with nutrition. Junctions where these arteries come together may develop weak spots that can balloon out and fill with blood, creating  aneurysms. These sac-like areas may leak or rupture, spilling blood into surrounding tissues which may cause artery spasm leading to potential stroke or even death. Clipping and coiling are two treatment options preferred by neurosurgeon which require proper detection of aneurysm. Medical practitioners are therefore emphasizing on the prior detection of cerebral aneurysm (CA) before rupture occurs leading to subarachnoid haemorrhage (SAH). This paper presents an efficient detection technique rooted in Modified Hough Circle Transform (MHCT) on the image extracted from Digital Subtraction Angiogram (DSA). Experimental results have firmly substantiated that the proposed method is highly efficient in properly detecting the location, size and type of aneurysm.

Comunicación y márketing: ¿convivencia o integración?
Authors: Rey Juan , Zambrano Paladines Mario , Zambrano Proaño Paola
Published: February 2018

En este trabajo se plantea la relación existente entre comunicación y marketing. Se parte de la revisión de los textos clásicos de la teoría del marketing y de las nuevas propuestas en el ámbito de la comunicación empresarial. Se cotejan analizando qué dice cada una acerca del papel que debe desempeñar la comunicación en la empresa. En principio se observa que, en el ámbito académico, existe controversia acerca de qué relación puede establecerse entre estas dos disciplinas. Aunque ambas coinciden en que focalizan su atención en la actividad comercial, no lo hacen de idéntica manera. El marketing se relaciona casi únicamente con el comercio, aunque también puede extenderse a otras actividades como la política. En cambio, la comunicación no se relaciona solo con el mundo de la venta. Su campo de acción es mucho más amplio. Afecta a todas las actividades del ser humano. Entre otras, a la comercial. Y este tipo de relación (exclusiva en el caso del marketing y eventual en el de la comunicación) es la que condiciona la perspectiva que se tiene acerca del papel que la comunicación ha de desempeñar en el mundo de la comercialización.
Nuevas propuestas para el análisis del lenguaje en los medios
Authors: Benavides Delgado Juan
Published: February 2018

En este trabajo, se propone la búsqueda de nuevos modelos para el aná­ lisis del lenguaje, partiendo de los complejos nexos existentes entre los medios de comunicación, la sociedad y los individuos que la componen. Se debate la relación entre lenguaje y cognición social desde diversos planteamientos  epistemológicos, desarrollados a partir de una concepción mentalista u otra centrada en los proce­ sos sociales y culturales. Finalmente, se plantean las ventajas de los distintos enfo­ ques teóricos, que pueden ser más o menos  útiles en función de las características de la investigación.
Las crisis del Habitar: Cine y publicidad en el Branded Content Cinergía – Gas Natural Fenosa
Authors: Rodríguez Serran Aarón , Gil Soldevilla Samuel , Marzal Felici Javier
Published: February 2018

El presente trabajo propone el análisis textual de los cuatro cortometrajes que conforman la campaña de Branded Content Cinergía (Paco Plaza, Rodrigo Cortés, Jaume Balagueró y Juan Cruz, 2015), generada para la compañía Gas Natural Fenosa. En dicho análisis, observamos cómo las distintas piezas utilizan los recursos audiovisuales habituales del género de terror para realizar una lectura crítica del habitar en el contexto de la actual crisis económica e ideológica. Para ello, en primer lugar explicitaremos la importancia del objeto de estudio, contextualizándolo después en la propia trayectoria publicitaria de Gas Natural – Fenosa. Estudiaremos las relaciones entre cine, energía y modos de habitar, tomando brevemente como antecedente el espot televisivo Happiness (Huigo Menduña, GNF, 2010). Una vez clarificados los antecedentes, mostraremos cómo en los cuatro cortometrajes se encuentran notables divergencias entre los objetivos y el posicionamiento de la marca y el propio contenido ficcional, tanto desde una perspectiva de forma fílmica como desde una perspectiva estrictamente narrativa. Para ello, analizaremos los cortometrajes en torno a tres parámetros distintos en los que se manifiestan los problemas del habitar contemporáneo: el marco de lo doméstico, el marco de la identidad subjetiva, y finalmente, el marco de la propia creación artística.
