Published: November 2016

The Chinese Small Telescope ARray (CSTAR) is the first Chinese astronomical instrument placed in Antarctica. It is a group of four identical, fully automatic

telescopes, with a field of view (FOV) of

centered on the South Celestial Pole. Placed at Antarctic Dome A, CSTAR is designed to provide high-cadence photometry for site monitoring and variable sources detection. During the 2008 observing season, CSTAR took high-precision photometric data of 18,145 stars around the South Celestial Pole. At

and 12, the photometric precision reaches ∼8 mmag and ∼30 mmag with a cadence of 20 s or 30 s, respectively. Using a robust detection method, we have found 15 stellar flares on 13 sources, including two classified variables. We have also found a linear relation between the decay times and the total durations of the stellar flares. The details of all the detected flares along with their stellar properties are presented in this work.

It has been proposed that mixing induced by convective overshoot can disrupt the inward propagation of carbon deflagrations in super-asymptotic giant branch stars. To test this theory, we study an idealized model of convectively bounded carbon flames with 3D hydrodynamic simulations of the Boussinesq equations using the pseudo-spectral code Dedalus. Because the flame propagation timescale is much longer than the convection timescale, we approximate the flame as fixed in space, and only consider its effects on the buoyancy of the fluid. By evolving a passive scalar field, we derive a turbulent chemical diffusivity produced by the convection as a function of height,

. Convection can stall a flame if the chemical mixing timescale, set by the turbulent chemical diffusivity,

, is shorter than the flame propagation timescale, set by the thermal diffusivity, κ, i.e., when

. However, we find

for most of the flame because convective plumes are not dense enough to penetrate into the flame. Extrapolating to realistic stellar conditions, this implies that convective mixing cannot stall a carbon flame and that “hybrid carbon–oxygen–neon” white dwarfs are not a typical product of stellar evolution.
MAGNETAR-POWERED SUPERNOVAE IN TWO DIMENSIONS. I. SUPERLUMINOUS SUPERNOVAE
Authors: Chen Ke-Jung , Woosley S. E. , Sukhbold Tuguldur
Published: November 2016

Previous studies have shown that the radiation emitted by a rapidly rotating magnetar embedded in a young supernova can greatly amplify its luminosity. These one-dimensional studies have also revealed the existence of an instability arising from the piling up of radiatively accelerated matter in a thin dense shell deep inside the supernova. Here, we examine the problem in two dimensions and find that, while instabilities cause mixing and fracture this shell into filamentary structures that reduce the density contrast, the concentration of matter in a hollow shell persists. The extent of the mixing depends upon the relative energy input by the magnetar and the kinetic energy of the inner ejecta. The light curve and spectrum of the resulting supernova will be appreciably altered, as will the appearance of the supernova remnant, which will be shellular and filamentary. A similar pile up and mixing might characterize other events where energy is input over an extended period by a centrally concentrated source, e.g., a pulsar, radioactive decay, a neutrino-powered wind, or colliding shells. The relevance of our models to the recent luminous transient ASASSN-15lh is briefly discussed.
FAR-UV EMISSION PROPERTIES OF FR1 RADIO GALAXIES

Published: November 2016

The power mechanism and accretion geometry for low-power FR 1 radio galaxies are poorly understood in comparison to those for Seyfert galaxies and QSOs. In this paper, we use the diagnostic power of the Lyα recombination line observed using the Cosmic Origins Spectrograph (COS) aboard the Hubble Space Telescope (HST) to investigate the accretion flows in three well-known, nearby FR 1s: M87, NGC 4696, and Hydra A. The Lyα emission line’s luminosity, velocity structure, and the limited knowledge of its spatial extent provided by COS are used to assess conditions within a few parsecs of the supermassive black hole in these radio-mode active galactic nuclei. We observe strong Lyα emission in all three objects with total luminosity similar to that seen in BL Lacertae objects. M87 shows a complicated emission-line profile in Lyα, which varies spatially across the COS aperture and possibly temporally over several epochs of observation. In both NGC 4696 and M87, the Lyα luminosities ∼1040 erg s−1 are closely consistent with the observed strength of the ionizing continuum in Case B recombination theory and with the assumption of a near-unity covering factor. It is possible that the Lyα-emitting clouds are ionized largely by beamed radiation associated with the jets. Long-slit UV spectroscopy can be used to test this hypothesis. Hydra A and the several BL Lac objects studied in this and previous papers have Lyα luminosities larger than M87 but their extrapolated, nonthermal continua are so luminous that they overpredict the observed strength of Lyα, a clear indicator of relativistic beaming in our direction. Given their substantial space density (∼4 × 10−3 Mpc−3), the unbeamed Lyman continuum radiation of FR 1s may make a substantial minority contribution (∼10%) to the local UV background if all FR 1s are similar to M87 in ionizing flux level.

Although there has been much progress in understanding how galaxies evolve, we still do not understand how and when they stop forming stars and become quiescent. We address this by applying our galaxy spectral energy distribution models, which incorporate physically motivated star formation histories (SFHs) from cosmological simulations, to a sample of quiescent galaxies at

. A total of 845 quiescent galaxies with multi-band photometry spanning rest-frame ultraviolet through near-infrared wavelengths are selected from the Cosmic Assembly Near-IR Deep Extragalactic Legacy Survey (CANDELS) data set. We compute median SFHs of these galaxies in bins of stellar mass and redshift. At all redshifts and stellar masses, the median SFHs rise, reach a peak, and then decline to reach quiescence. At high redshift, we find that the rise and decline are fast, as expected, because the universe is young. At low redshift, the duration of these phases depends strongly on stellar mass. Low-mass galaxies (

) grow on average slowly, take a long time to reach their peak of star formation (

Gyr), and then the declining phase is fast (

Gyr). Conversely, high-mass galaxies (

) grow on average fast (

Gyr), and, after reaching their peak, decrease the star formation slowly (

). These findings are consistent with galaxy stellar mass being a driving factor in determining how evolved galaxies are, with high-mass galaxies being the most evolved at any time (i.e., downsizing). The different durations we observe in the declining phases also suggest that low- and high-mass galaxies experience different quenching mechanisms, which operate on different timescales.
THE SYSTEMATICS OF STRONG LENS MODELING QUANTIFIED: THE EFFECTS OF CONSTRAINT SELECTION AND REDSHIFT INFORMATION ON MAGNIFICATION, MASS, AND MULTIPLE IMAGE PREDICTABILITY
Authors: Johnson Traci L. , Sharon Keren
Published: November 2016

Until now, systematic errors in strong gravitational lens modeling have been acknowledged but have never been fully quantified. Here, we launch an investigation into the systematics induced by constraint selection. We model the simulated cluster Ares 362 times using random selections of image systems with and without spectroscopic redshifts and quantify the systematics using several diagnostics: image predictability, accuracy of model-predicted redshifts, enclosed mass, and magnification. We find that for models with >15 image systems, the image plane rms does not decrease significantly when more systems are added; however, the rms values quoted in the literature may be misleading as to the ability of a model to predict new multiple images. The mass is well constrained near the Einstein radius in all cases, and systematic error drops to <2% for models using >10 image systems. Magnification errors are smallest along the straight portions of the critical curve, and the value of the magnification is systematically lower near curved portions. For >15 systems, the systematic error on magnification is ∼2%. We report no trend in magnification error with the fraction of spectroscopic image systems when selecting constraints at random; however, when using the same selection of constraints, increasing this fraction up to ∼0.5 will increase model accuracy. The results suggest that the selection of constraints, rather than quantity alone, determines the accuracy of the magnification. We note that spectroscopic follow-up of at least a few image systems is crucial because models without any spectroscopic redshifts are inaccurate across all of our diagnostics.
PHASE QUANTIZATION STUDY OF SPATIAL LIGHT MODULATOR FOR EXTREME HIGH-CONTRAST IMAGING
Authors: Dou Jiangpei , Ren Deqing
Published: November 2016

Direct imaging of exoplanets by reflected starlight is extremely challenging due to the large luminosity ratio to the primary star. Wave-front control is a critical technique to attenuate the speckle noise in order to achieve an extremely high contrast. We present a phase quantization study of a spatial light modulator (SLM) for wave-front control to meet the contrast requirement of detection of a terrestrial planet in the habitable zone of a solar-type star. We perform the numerical simulation by employing the SLM with different phase accuracy and actuator numbers, which are related to the achievable contrast. We use an optimization algorithm to solve the quantization problems that is matched to the controllable phase step of the SLM. Two optical configurations are discussed with the SLM located before and after the coronagraph focal plane mask. The simulation result has constrained the specification for SLM phase accuracy in the above two optical configurations, which gives us a phase accuracy of 0.4/1000 and 1/1000 waves to achieve a contrast of 10−10. Finally, we have demonstrated that an SLM with more actuators can deliver a competitive contrast performance on the order of 10−10 in comparison to that by using a deformable mirror.
THE LOST DWARFS OF CENTAURUS A AND THE FORMATION OF ITS DARK GLOBULAR CLUSTERS
Authors: Bovill Mia Sauda , Puzia Thomas H. , Ricotti Massimo , Taylor Matthew A.
Published: November 2016

We present theoretical constraints for the formation of the newly discovered dark star clusters (DSCs) with high mass-to-light (

) ratios, from Taylor et al. These compact stellar systems photometrically resemble globular clusters (GCs) but have dynamical

ratios of ∼10–100, closer to the expectations for dwarf galaxies. The baryonic properties of the DSCs suggest that their host dark matter halos likely virialized at high redshift with

. We use a new set of high-resolution N-body simulations of Centaurus A to determine whether there is a set of z = 0 subhalos whose properties are in line with these observations. While we find such a set of subhalos, when we extrapolate the dark matter density profiles into the inner 20 pc, no dark matter halo associated with Centaurus A in our simulations, at any redshift, can replicate the extremely high central mass densities of the DSCs. Among the most likely options for explaining 105–

within subhalos of 10 pc diameter is the presence of a central massive black hole (BH). We therefore propose that the DSCs are remnant cusps of stellar systems surrounding the central BHs of dwarf galaxies that have been almost completely destroyed by interactions with Centaurus A.
MERGING GALAXIES WITH TIDAL TAILS IN COSMOS TO z = 1
Authors: Wen (闻璋正) Zhang Zheng , Zheng (郑宪忠) Xian Zhong
Published: November 2016

Tidal tails are created in major mergers involving disk galaxies. It remains to be explored how the tidal tails trace the assembly history of massive galaxies. We identify a sample of 461 merging galaxies with long tidal tails, from 35,076 galaxies mass-complete at

and

, based on Hubble Space Telescope/ACS F814W imaging data and public catalogs of the COSMOS field. The long tails refer to those with length equal to or greater than the diameter of their host galaxies. The mergers with tidal tails are selected using our novel

technique for strong asymmetric features, along with visual examination. Our results show that the fraction of tidal-tailed mergers evolves mildly with redshift, as

, and becomes relatively higher in less-massive galaxies, out to z = 1. With a timescale of 0.5 Gyr for the tidal-tailed mergers, we obtain that the occurrence rate of such mergers follows

Gyr−1, and corresponds to ∼0.3 events since z = 1,  as well as roughly one-third of the total budget of major mergers from the literature. For disk-involved major mergers, nearly half of them have undergone a phase with long tidal tails.
GRAVITY-DARKENED SEASONS: INSOLATION AROUND RAPID ROTATORS
Authors: Ahlers John P.
Published: November 2016

I model the effect of rapid stellar rotation on a planet’s insolation. Fast-rotating stars have induced pole-to-equator temperature gradients (known as gravity darkening) of up to several thousand Kelvin that affect the star’s luminosity and peak emission wavelength as a function of latitude. When orbiting such a star, a planet’s annual insolation can strongly vary depending on its orbital inclination. Specifically, inclined orbits result in temporary exposure to the star’s hotter poles. I find that gravity darkening can drive changes in a planet’s equilibrium temperature of up to ∼15% due to increased irradiance near the stellar poles. This effect can also vary a planet’s exposure to UV radiation by up to ∼80% throughout its orbit as it is exposed to an irradiance spectrum corresponding to different stellar effective temperatures over time.

Ratio de levier à la Bâle III : quel impact sur l’offre de crédit et la stabilité bancaire ?
Authors: Spinassou Kévin
Published: November 2016

Cet article présente un modèle théorique analysant les conséquences de l’ajout d’un ratio de levier à un ratio de capital pondéré du risque, en termes d’offre de crédit et de stabilité bancaire. Nous montrons que la mise en place d’un ratio de capital pondéré du risque permet de réduire l’instabilité bancaire sans modifier l’offre de crédit dans l’économie, mais que l’ajout d’un ratio de levier réduit l’offre de crédit sans nécessairement améliorer la stabilité bancaire. Cette stabilité bancaire est renforcée par un ratio de levier seulement dans le cas où le régulateur bénéficie d’un faible pouvoir en termes d’audits et de sanctions des banques. Nos résultats soulignent donc l’importance de la prise en compte de l’offre de crédit dans les préoccupations des régulateurs, notamment en Europe où le financement de l’économie passe principalement par l’offre de crédit des banques.
The Impact of the Banking Competition in Funding and Lending Markets on Lending Technology
Authors: Ahn Jung-Hyun
Published: November 2016

Le recours aux techniques de credit scoring dans les décisions d’octroi de crédit bancaire s’est largement accru, au détriment des méthodes traditionnelles basées sur la relation clientèle. J’analyse le lien entre cette évolution et la concurrence bancaire, et ses conséquences sur l’efficience, dans un modèle de double concurrence dans lequel deux banques disposant de technologies différentes d’octroi de crédit se concurrencent à la fois sur un marché de fonds et sur deux marchés de crédit hétérogènes. La concurrence peut générer une inefficience lorsqu’une banque surenchérit sur le marché de fonds pour jouir d’un pouvoir de monopole sur tous les marchés de crédit en éliminant son concurrent disposant d’une technologie plus efficiente sur un marché de crédit.

La victoire à trois points dans le football a-t-elle rendu les équipes plus offensives ?
Authors: Duhautois Richard , Eyssautier Romain
Published: November 2016

Dans les années 1990, la règle de la victoire à trois points a été introduite par les fédérations de football. Le système 2 points pour une victoire, 1 point pour le match nul et 0 point pour une défaite a été remplacé par 3 points pour une victoire, 1 point pour un match nul et 0 point pour une défaite. Le but de cette réforme était d’augmenter la récompense obtenue lors d’une victoire afin d’influencer les tactiques des équipes et de les rendre plus offensives. Nous comparons la part des matchs nuls avant et après la réforme dans le Championnat de France de première division et la Coupe de France. En utilisant une méthode d’estimation en doubles différences, nous montrons que la répartition des victoires est affectée par le changement de règle : la part des victoires à l’extérieur a augmenté et la part des victoires à domicile a diminué, laissant inchangée la part des matchs nuls.
Proudhon et la question coloniale algérienne
Authors: Zouache Abdallah
Published: November 2016

L’article s’intéresse à l’analyse économique de la question coloniale algérienne par Pierre-Joseph Proudhon. Son positionnement semble peu connu dans la littérature. Proudhon propose une théorie institutionnaliste du droit de la force à partir de laquelle il est possible de penser la colonisation dans un cadre raciste. Ce cadre fournit les prémices d’une économie coloniale algérienne. L’article examine également la cohérence entre le système de Proudhon et sa vision coloniale. Le principal résultat est que la question coloniale intervient comme un cas particulier qui ne relève pas des principes dérivés à partir des écrits de Proudhon, en particulier les principes de justice, d’égalité, de liberté et de propriété.

Published: November 2016

Ce travail examine les effets du terrorisme sur la croissance économique en Inde. En utilisant un modèle de Markov à changement de régime, on trouve des preuves que le terrorisme a des effets importants et négatifs sur la croissance économique de l’Inde. Nos résultats empiriques montrent aussi que l’ampleur de ces effets est plus grande dans des périodes de haute croissance économique. Enfin, nous comparons l’ampleur des effets de « brutalité » et de « fréquence » des attaques terroristes et nous concluons que l’effet de « fréquence » est légèrement plus élevé que l’effet de « brutalité ».

La balance du carbone incorporé au commerce bilatéral entre la France et la Chine : transferts d’émissions ou nouvelles créations ?
Authors: He Jie , Jacquemin Johan
Published: November 2016

Nous calculons la balance des émissions de carbone incorporées au commerce (BEIC) bilatéral franco-chinois entre 1996 et 2005. Les résultats confirment le rôle d’exportateur net en carbone de la Chine et l’augmentation rapide de l’excédent de la BEIC depuis l’adhésion de la Chine à l’Organisation mondiale du commerce. Cependant, la quasi-totalité de cet excédent est due à la faible efficacité en carbone de la Chine par rapport à la France. La part de carbone émis sur le sol chinois réellement transféré de la France vers la Chine reste très faible (1-2 %). Le commerce franco-chinois semble continuer à profiter essentiellement de leurs différences de dotations factorielles. L’avantage comparatif issu des réglementations environnementales ne joue qu’un rôle marginal.
Las secuelas de la crisis a través de la en la información financiera de las empresas de la distribución y el comercio al por menor español: pequeñas Vs grandes empresas
Authors: Ramón Dangla Remedios
Published: November 2016

Purpose: In this paper, we analyze the evolution of the financial information of companies in the retail trade sector to show how and how much the actual crisis has affected them.Design/methodology: In this paper, we have established the hypothesis about the particular behavior of the sector due to its specialization in the sale of basic goods and the strong position of the trade chain in the market. For the analysis we searched an example of companies from the SABI database, then we sorted the sample by size and linked theirs to per capita income and domestic consumption through a lineal regression. We looked for the economic variable than were explaining the evolution of the results of the sector better and studied the evolution of efficiency, operability, profitability or financial solvency ratios. We analyzed the statistically significant changes on the accounting ratios depending of the company size.Findings: The retail trade sector could be could be listed as counter-cyclical sector but all companies have lost profitability although the small ones have lost more and have had to reorganize their financial structure as a result of the crisis. On the contrary, the big companies have kept their high level of indebtedness and even their negative working capital. The specialization in the sale of products with a low elasticity demand-income and the power in the markets have allowed that these big companies don´t suffer important changes in their revenue and expenditure results.Research limitations/implications: This investigation describes and analyzes, with statistical techniques, the evolution of several accounting ratio of the companies of the retail and the relation with economics variables. However, a study of other financial information and the utilization of other statistical techniques could explain with more accuracy the reasons of these results.Originality/value: On very few occasions the retail sector has been analyzed through their financial statements. The actual crisis has caused a restructuration in most of the companies, specially in the indebtedness level. However, the big companies of the retail sector haven´t needed deleverage. The difference of the crisis effect between companies of different sectors and between the size of the same sector, is presented as a different approach.
Intensidad exportadora y fortalezas percibidas en la estrategia de marketing: Una perspectiva basada en la experiencia de empresas exportadoras españolas
Authors: Castro-González Pilar , Gutiérrez-Villar Belén , Araque-Padilla Rafael Ángel , Montero-Simó María José
Published: November 2016

Purpose: This paper studies if there are associations between export profiles of some Spanish companies –high or low export intensity- and the opinion of managers about strengths generated in the marketing mix.Design/methodology: Through a questionnaire to 64 export Spanish companies and the literature review, we defined the export intensity as the dependent variable. The explanatory variables used measure the importance granted by the companies to the different variables of the marketing mix as strengths for export activity. We used MANOVA method as it lets us analyze differences between two or more metrical dependent variables (quality, price, promotion and place) based on a mix of categorical variables that act like predictors (export volume).Findings: Our results indicate that a correct planning of the marketing strategy is a key aspect inside internationalization strategy. In contrast with other studies that analyze specific strategies within marketing mix, this research focuses on these as perceived competitive strengths, whichever the mix of variable strategy that generates these strengths is.Practical implications: The differences observed indicate that there are different patterns in the marketing mix strength evaluation. The results show that the firms which have the most export intensity have generated bigger capacities especially in distribution channels configuration and promotion strategies.Originality/value: The main differentiating element in this research is the combines focus on the marketing mix variables as competitive strengths while distinguishing each of them.
Comparison of 360-Degree Circumferential Trabeculotomy and Conventional Trabeculotomy in Primary Pediatric Glaucoma Surgery: Part 1
Authors: Celea Christiana , Dragosloveanu Serban , Pop Mihai , Celea Cristian
Published: November 2016

Purpose:

To quantify the outcomes of a single circumferential trabeculotomy versus a single conventional trabeculotomy after 2 years of follow-up in patients who underwent primary pediatric glaucoma surgery.

Methods:

This was a retrospective study of patients aged 1 day to 3 years who underwent primary pediatric glaucoma surgery. A total of 45 patients (79 eyes) were followed up for 2 years. There were two groups: the 360-degrees circumferential trabeculotomy with illuminated catheter group and the conventional trabeculotomy group.

Results:

Mean age was 5.37 ± 6.32 months. There were 41 eyes with circumferential trabeculotomy and 38 eyes with conventional trabeculotomy. In the circumferential group, the technique could not be completed in 3 eyes (7.31%) because of severe canal malformations. Mean intraocular pressure and corneal diameter decreased in both groups postoperatively. At 2 years' follow-up, intraocular pressure (IOP) decreased, with 13.61 mm Hg in the circumferential group and 9.09 mm Hg in the conventional group. At 6 months postoperatively, corneal diameter decreased, with 0.52 mm in the circumferential group and 0.27 mm in the conventional group. Axial length remained the same.

Conclusions:

Both procedures were successful, but circumferential trabeculotomy was better than the conventional procedure for lowering IOP, with an average of 4.52 mm Hg at 2 years' follow-up. The decrease in postoperative corneal diameter was also better in the circumferential group. The mean preoperative and postoperative axial lengths were similar in both groups; thus, the surgery did not influence this measurement in the studied cases.

Cervantes, fray Juan Gil y los mercaderes valencianos
Authors: Villalmanzo Jesús
Published: November 2016

En el artículo se dan a conocer varios documentos inéditos referentes a Cervantes, Fray Juan Gil y a varios mercaderes amigos de ambos personajes. Están fechados principalmente en los años 1580-1592, época de los viajes redentores a Argel del padre Gil e inmediatos sucesores, fecha también de la liberación de Cervantes y de su posterior estancia en Valencia. Especial interés tienen los documentos relativos a los contratos de fletamento de las naves redentoras. Digno de destacar es la sorprendente intervención de Cervantes, ofreciendo información de primera mano sobre un cautivo de Argel. Los que recibieron esta información, unos mercaderes sin escrúpulos, urdieron unas fraudulentas apuestas, donde se jugaron altas cantidades de dinero, en las que se vieron implicados varios centenares de personas acaudaladas, como mercaderes y maestros artesanos. Se apostaba sobre la vida o muerte de un pescador del Grao al que se daba por muerto, víctima de unos supuestos criminales que se hallaban detenidos en las cárceles de Valencia.
La lengua literaria cervantina en El comedido hidalgo de Eslava Galán
Authors: Monterrubio Prieto Juan Miguel , Servera Baño José
Published: November 2016

El propósito de este trabajo es estudiar en qué medida y de qué manera Eslava incorpora a su novela, El comedido hidalgo, la lengua y las técnicas literarias cervantinas. Se ha apuntado que Cervantes creaba, en determinados pasajes, una lengua arcaica, de aspecto medieval. Eslava, por su parte, inventa un lenguaje, nuevo en cuanto que no es fiel copia del habla utilizada en los siglos XVI y XVII, pero de efecto evocador. El estudio muestra cómo la novela adapta buena parte de los recursos literarios del autor del Quijote de forma un tanto diferente y novedosa. No se trata de una mera reproducción de las técnicas literarias cervantinas, sino de una hiperbolización, a veces transgresora, de las mismas, como sostén de una visión crítica, irónica y burlesca, de la España áurea.

Looking through the Vizão Feita por Xpo a el Rey Dom Affonso Henriques (1659) Franciscans in India and the legitimization of the Braganza monarchy
Authors: Barreto Xavier Ângela
Published: November 2016

Early modern Portuguese political providentialism has attracted significant scholarly interest in recent years. Whether in reference to the legitimization of imperialism in the fifteenth and sixteenth centuries, to the divine justification of royal power in the sixteenth and seventeenth centuries (especially after 1640), to Sebastianism, the Fifth Empire and other forms of millenarism, or to the uses of astrology, scholars have demonstrated that political providentialism was a familiar language to the Portuguese monarchy.

Little is known, however, about the formulation and spread of political providentialism in the Asian part of the Portuguese Empire. In this paper I provide a more complex picture of the dissemination of this language in the Estado da Índia through an analysis of the treatise Vizão de Affonso Henriques, written in Goa by Friar António de S. Thiago, in the year 1659. How does this treatise relate to metropolitan political providentialism, namely in the context of the legitimization of the Braganza monarchy? How is Franciscanism crucial in the treatise’s structure? And can the treatise be located at the crossroads of Euro-Asiatic political culture?
The Temporal Politics of Spiritual Conquest: History, Geography and Franciscan Orientalism in the Conquista Espiritual do Oriente of Friar Paulo da Trindade
Authors: Biedermann Zoltán
Published: November 2016

This article queries the relationship between imperial expansion, geographical knowledge and epistemic spatiality in Portuguese Asia. It proposes to disentangle these aspects by exploring the Conquista Espiritual do Oriente of Friar Paulo da Trindade, a Lusophone, Asian-born Franciscan writing in Goa in the 1630s. Trindade’s chronicle provides disturbing insights into the difficult relationship between imperial expansion and the spatial organization of knowledge. Information about Asia and its peoples appears systematically detached from the spatial frameworks created by other authors and thrown into a panorama deeply reliant on spirituality and sacred history. Trindade’s work suggests that there were strong political reasons for the Order of Saint Francis to embrace such a narrative. Whilst generalizations remain to be avoided, the shadow cast by the Jesuits over the Franciscan enterprise in the East played a key role in the adoption by the Seraphic order of a discursive strategy where time trumped space.
In search of “Franciscan” Brazil: memory and territorialization in Friar António Maria Jaboatão’s Orbe Seraphico Brasilico (1761)
Authors: Santos Zulmira C.
Published: November 2016

The main objective of this article is the study of the chronicle Orbe Serafico Novo Brazilico, by the Franciscan Friar Antonio Maria Jaboatão. The article attempts to study the ways in which the chronicle’s textual organization contributes towards a ‘Franciscanization’ of Brazil, at a time when the Society of Jesus, having been expelled from Portugal in 1759, found itself in a very difficult situation. Even though the idea of a “Franciscan World” has its roots in much older models, Friar Jaboatao’s chronicle presents a model of evangelization different from that of the Society of Jesus. He emphasizes the territorial dimension by creating a “geography” of Franciscan churches and convents, thus symbolically appropriating the Brazilian territory.
The Impossible Performance of Mass Commodity. George Maciunas, Herman Fine and Robert Watts’ Implosions Inc. (ca. 1967)
Authors: Estella Noriega Iñaki
Published: November 2016

In the US context Fluxus is understood as an advance of the ‘60s radicalism. The assumption that Fluxus was opposed to consumption culture, as that embodied by Pop art, is among the interpretations that renew such a view. Examining the example of Implosions Inc., a short-lived but nevertheless interesting commercial enterprise formed by Robert Watts, Herman Fine and George Maciunas in 1967, this essay focuses its attention on the complex relationship between Fluxus and commercial culture. Implosions Inc. was a project in which many Pop artists were asked to participate along with its Fluxus founders, and it was intended as another step forward in the transformation of the artist into a commodity mass-producer. In analyzing this phenomenon, this article questions assumed principles in the Neo-avantgarde theory like the distinction between art production and culture consumption. The essay, however, will try to establish another paradigm that draws the differences between Pop art and Fluxus as the kind of audiences both these tendencies tried to conform. As a conclusion, the article fleshes out some ideas on individualism that were developed by Maciunas, which shed light on the notions surrounding the idea of collectivism as developed in Fluxus.

Authors: Baize-Varin Marie
Published: November 2016

Cet article traite de la spécificité de l’enseignement de l’arabe aux Écoles de Saint-Cyr Coëtquidan (ESCC), école de formation initiale des officiers de l’armée de Terre française. Il montre en quoi l’enseignement de l’arabe y est particulièrement révélateur de la pluriglossie de cette langue, puisque dépendant ici des besoins des apprenants. En effet, l’arabe, en tant que langue de spécialité militaire – si nous abordons d’un point de vue lexical le concept de langue de spécialité - est étudié par deux publics différents. Cependant, étant donné que les élèves-officiers des ESCC sont considérés comme « spécialistes d’autres disciplines » et que la formation qui y est délivrée est dite « intégrée » (militaire, académique et comportementale), nous pouvons voir ici une convergence entre Lansad et langue de spécialité. Encore faut-il déterminer de quel(s) arabe(s)il s’agit.
Algorithms for Maintaining Consistency of Cached Data for Mobile Clients in Distributed File System
Authors: Bžoch Pavel , Šafařík Jiří
Published: November 2016

A cache stores data in order to serve future requests to those data faster. In mobile devices, the data have to be transferred from a server through the mobile network before being stored in the cache. The mobile network is prone to failure caused by users' movements and by the placement of base transceiver stations. Moreover, the mobile devices use various telecommunications technologies and therefore the speed of the network is highly variable. Using a cellular network for communication is also expensive. The cache is an intermediate component which addresses this problem. Once the data are downloaded, they can be stored in the cache for possible future reuse. When using a cache, the system designer presumes that the data will be requested again in the future. On the other hand, the original data stored on the server can be changed. Then, the cached data are in an inconsistent state. In this paper, authors present an adaptive method for maintaining the consistency of cached data which saves network traffic by reducing the number of messages needed for inconsistency detection.

Authors: Maratha Barakat Pravin , Sheltami Tarek R. , Shakshuki Elhadi M.
Published: November 2016

Vehicular Ad-Hoc Network (VANET) has been derived from the well-established Mobile Ad-hoc Network (MANET). It facilitates wireless communication among vehicles to roadside equipment. Such kind of communication is utilized for different purposes such as safety, comfort, or even entertainment. The performance of VANET applications are highly determined by its underlying routing protocols. In this paper, the authors investigate the performance of topology based MANET routing protocols (AODV, DSDV and DSR) in a VANET highway design using NCTUNS 6.0 simulator. Different parameters are varied including speed, node density, propagation loss model, fading effects, data rate and payload. The selected routing protocols are then evaluated in terms of performance metrics throughput, packet drop and packet collision. Results shows that the performance of routing protocols depends on the application requirements in terms of throughput, delay and percentage of packet drops.

Authors: Behera Rabi Narayan , Dash Sujata
Published: November 2016

Due to rapid digital explosion user shows interest towards finding suggestions regarding a particular topic before taking any decision. Nowadays, a movie recommendation system is an upcoming area which suggests movies based on user profile. Many researchers working on supervised or semi-supervised ensemble based machine learning approach for matching more appropriate profiles and suggest related movies. In this paper a hybrid recommendation system is proposed which includes both collaborative and content based filtering to design a profile matching algorithm. A nature inspired Particle Swam Optimization technique is applied to fine tune the profile matching algorithm by assigning to multiple agents or particle with some initial random guess. The accuracy of the model will be judged comparing with Genetic algorithm.
The Use of 2 Conditioning Programs and the Fitness Characteristics of Police Academy Cadets
Authors: Cocke Charles , Dawes Jay , Orr Robin Marc
Published: November 2016

Context: Police academy training must physically prepare cadets for the rigors of their occupational tasks to prevent injury and allow them to adequately perform their duties.

Objective: To compare the effects of 2 physical training programs on multiple fitness measures in police cadets.

Design: Cohort study.

Setting: Police training academy.

Patients or Other Participants: We collected data from 70 male (age = 27.4 ± 5.9 years, body weight = 85.4 ± 11.8 kg) and 20 female (age = 30.5 ± 5.8 years, body weight = 62.8 ± 11.0 kg) police cadets and analyzed data from 61 male cadets (age = 27.5 ± 5.5 years, body weight = 87.7 ± 13.2 kg).

Intervention(s): Participants completed one of two 6-month training programs. The randomized training group (RTG; n = 50), comprising 4 separate and sequential groups (n = 13, n = 11, n = 13, n = 13), completed a randomized training program that incorporated various strength and endurance exercises chosen on the day of training. The periodized group (PG; n = 11) completed a periodized training program that alternated specific phases of training.

Main Outcome Measure(s): Anthropometric fitness measures were body weight, fat mass, and lean body mass. Muscular and metabolic fitness measures were 1-repetition maximum bench press, push-up and sit-up repetitions performed in 1 minute, vertical jump, 300-m sprint, and 2.4-km run.

Results: The RTG demonstrated improvements in all outcome measures between pretraining and posttraining; however, the improvements varied among the 4 individual RTGs. Conversely, the PG displayed improvements in only 3 outcome measures (push-ups, sit-ups, and 300-m sprint) but approached the level of significance set for this study (P < .01) in body weight, fat mass, and 1-repetition maximum bench press.

Conclusions: Regardless of format, physical training programs can improve the fitness of tactical athletes. In general, physical fitness measures appeared to improve more in the RTG than in the PG. However, this observation varied among groups, and injury rates were not compared.
Race, whiteness and transformation in the Promise Keepers America and the Mighty Men Conference: A comparative analysis
Authors: Dube Siphiwe
Published: November 2016

This article takes cue from Sarojini Nadar’s article analysing the Mighty Men Conference (MMC) in South Africa as a case study of masculinism, where the author makes some passing comparison between Promise Keepers in America (PKA) and the MMC in South Africa. This article investigates the specific ways in which PKA and MMC are ideologically similar, while also evaluating how their differences accrue dissimilar results with respect to their missions on race reconciliation. The article argues that despite their shared religious similarities as evangelical Christian men’s organisations and perceptions regarding the ‘crisis in/of masculinity’, race discourse plays different roles in the ministries of PKA and MMC. The key observation arising from addressing this discourse is that in the context of PKA, the organisation’s institutional focus on race translates itself into discussions and debates about race reconciliation amongst the various racialised men of the movement as part of the organisation’s work of self-transformation. However, such talk, although present at the individual level to some extent in the MMC, is absent at the institutional level. The absence of such discourse is especially problematic given the visibility of race in public discourse in South Africa, in general, and also points to a masked refusal to give up white male privilege in the post-apartheid public sphere.
Discerning a theological agenda for spatial justice in South Africa: An imperative for sustained reconciliation
Authors: De Beer Stephan
Published: November 2016

A spatial turn has occurred in various disciplines over the past decades. This article holds that it has not occurred in a similar decisive manner in theological discourse and not in South Africa in particular. After considering the necessity of a spatial turn and spatial consciousness, the article examines the concept of spatial justice against the backdrop of how injustice was and is spatially expressed in South African cities. Considering the way in which South African cities have evolved since the Native Land Act of 1913 – the segregated and apartheid city and the (post)apartheid city – the article then argues that deep and sustained reconciliation will be impossible should current spatial patterns of segregation, exclusion and injustice continue. It advocates theological and ecclesial participation in a national agenda for spatial transformation, to be fleshed out in relation to four interconnected challenges: land, landlessness, housing and home; the ‘creative destruction’ of neighbourhoods, gentrification and the displacement of the poor; participation in city-making (from below) and transformative spatial interventions; and close collaboration with social movements working for spatial justice. It concludes by asserting that such a trans- and/or postdisciplinary agenda for spatial justice would participate with the Spirit to mend the oikos of God.
The importance of the Dead Sea Scrolls for the study of the explicit quotations in Ad Hebraeos
Authors: Steyn Gert J.
Published: November 2016

The important contribution that the Dead Sea Scrolls (DSS) hold for New Testament studies is probably most evident in Ad Hebraeos. This contribution seeks to present an overview of relevant extant DSS fragments available for an investigation of the Old Testament explicit quotations and motifs in the book of Hebrews. A large number of the explicit quotations in Hebrews were already alluded to, or even quoted, in some of the DSS. The DSS are of great importance for the study of the explicit quotations in Ad Hebraeos in at least four areas, namely in terms of its text-critical value, the hermeneutical methods employed in both the DSS and Hebrews, theological themes and motifs that surface in both works, and the socio-religious background in which these quotations are embedded. After these four areas are briefly explored, this contribution concludes, among others, that one can cautiously imagine a similar Jewish sectarian matrix from which certain Christian converts might have come – such as the author of Hebrews himself.
Coastal erosion management in Accra: Combining local knowledge and empirical research
Authors: Appeaning Addo Kwasi , Appeaning Addo Irene
Published: November 2016

Coastal erosion along the Accra coast has become a chronic phenomenon that threatens both life and property. The issue has assumed a centre stage of national debate in recent times because of its impact on the coastal communities. Lack of reliable geospatial data hinders effective scientific investigations into the changing trends in the shoreline position. However, knowledge about coastal erosion, by the local people, and how far the shoreline has migrated inland over time is high in the coastal communities in Accra. This opens a new chapter in coastal erosion research to include local knowledge of the local settlers in developing sustainable coastal management. This article adopted a scientific approach to estimate rate of erosion and tested the results against perceived erosion trend by the local settlers. The study used a 1974 digital topographic map and 1996 aerial photographs. The end point rate statistical method in DSAS was used to compute the rates of change. The short-term rate of change for the 22-year period under study was estimated as -0.91 m/annum ± 0.49 m/annum. It was revealed that about 79% of the shoreline is eroding, while the remaining 21% is either stabilised or accreting. It emerged, from semi-structured interviews with inhabitants in the Accra coastal communities, that an average of about 30 m of coastal lands are perceived to have been lost to erosion for a period of about 20 years. This translates to a historic rate of change of about 1.5 m/year, which corroborates the results of the scientific study. Again this study has established that the local knowledge of the inhabitants, about coastal erosion, can serve as reliable information under scarcity of scientific data for coastal erosion analyses in developing countries.
