Glauber en trance: el tiempo como dimensión social en la poesía de Paulo Martins
Authors: Barrós Manuel 
Published: August 2018

En el presente estudio analizo el tiempo como dimensión social en la estética de Terra em transe (1967) a través de la poesía de Paulo Martins, alter ego de Glauber Rocha. A partir de las ideas de Brecht propongo que el lenguaje poético verbal tuvo una gran importancia, pues mediante sus representaciones temporales se puede rastrear su relevancia lírica: por su dramaticidad y capacidad de transmitir los tránsitos emocionales y oscilaciones políticas del protagonista. Al analizar su especificidad estética, ésta remite a su compleja relación con los otros lenguajes comprendidos en el registro fílmico y aportes a la realización de la película en el contexto de la dictadura militar brasileña (1964-1985).
Organización del sistema de reglas de la tilde en el español: fundamentos lingüísticos
Authors: Mamani Quispe Luis Alberto 
Published: August 2018

Tras mostrar que las reglas vigentes del acento gráfico en español exhiben incoherencias e inconsistencias, en el presente trabajo se plantea una manera diferente de organizarlas. Para desarrollar la propuesta se ha recurrido a la teoría de los sistemas complejos debido a que las normas del acento gráfico están incardinadas en el sistema de escritura del español y a que se relacionan con unidades del sistema lingüístico. Ello nos ha permitido mostrar que la organización de las reglas no puede realizarse al margen del ordenamiento de las palabras. Teniendo como base esto último se propone cuatro clases de tildes sin reglas generales, sin excepciones y sin reglas de carácter prohibitivo. La principal consecuencia, en términos de su utilidad, es que la enseñanza de la tilde no puede empezar por las reglas generales, sino por las palabras con hiato.
Elementos para el proceso y corpus de la narrativa quechua contemporánea
Authors: Espino Relucé Gonzalo 
Published: August 2018

La conquista de la letra significó para los uechuahablantes experimentación y exploración de nuevas formas de expresión. Ello sucedería hacia mitad del siglo XX, cuando en Cusco y en Huanta se difundieron los primeros relatos y poemas escritos por quechuas. Planteamos que estas narrativas se consolidan a fines del siglo XX e inicios del XXI como manifestaciones independientes que alcanzanla conformación de un corpus no solo respetable sino representativo. Nuestra investigación se propone visibilizar el corpus de la narrativa quechua; tomará como referente temporal 1980-2015 y sitúa su estudio en la producción quechua del Perú. Estas narrativas forman parte de la modernización del país a partir del siglo XX; atiende básicamente a las manifestaciones escritas, no a las formas orales, aunque inevitablemente las vincularemos a ellas.
Identidades y preferencias lingüísticas en comunidades de la Selva Central del Perú
Authors: Falcón Ccenta Pedro Manuel 
Published: August 2018

El propósito del estudio es analizar, desde la perspectiva teórico-mentalista, las preferencias lingüísticas de los pobladores indígenas bilingües-amazónicos en términos afectivos, cognoscitivos y socioculturales. Para ello, se evalúan los factores como edad, sexo, escolaridad y procedencia que condicionan las actitudes positivas o negativas hacia las lenguas originarias y hacia el castellano. Estos factores, además, comprometen las identidades, los niveles de autoestima y los soportes socioculturales. Asimismo, en este contexto permiten comprender con mayor objetividad la predisposición valorativa de los usuarios indígenas respecto a su propia lengua y hacia el castellano en conexión con los elementos de identificación sociocultural o el distanciamiento con su grupo que, sin duda, comprometen seriamente la vulnerabilidad de las lenguas.
Escritura y realidad en tres cuentos de Leonardo Padura: estructura metonímica de la prosa como procedimiento de desjerarquización
Authors: Mondoñedo Marcos 
Published: August 2018

Este trabajo desarrolla un análisis de los procedimientos retóricos propios de la prosa de algunos cuentos de Leonardo Padura: “Según pasan los años”, “El cazador”, “La puerta de Alcalá”. En ellos se configuraría una suerte de “aplanamiento” de los diversos elementos de la representación narrativa. Este procedimiento puede describirse como una continuidad metonímica o como una “textualización” de diversos planos de inmanencia semiótica, lo cual traería como consecuencia una especial verosimilitud narrativa: la realidad ficcional y la realidad histórica se continúan disolviendo sus límites y sin aparente cambio de nivel de pertinencia. De este modo, se extienden los dominios de la ficción al campo de las formas de vida y se proyectan dichas formas a la inmanencia textual.
Examining the Moderating Role of Self-monitoring in Predicting Employees Speaking Up Behavior at Workplace
Authors: Khan Noor Ullah 
Published: August 2018

The objective of the present study was to investigate the relationship and moderating effects of self-monitoring on the relationship between various individual (viz., the locus of control and self-esteem) and contextual (viz., top-management openness and trust in supervisor) factors by predicting speaking up the behavior of employees at the workplace. A sample size of 95 was selected via random probability sampling out of 318 employees from nine management and business institutions or departments of different universities in Peshawar KPK Pakistan. The conclusion drawn from the research study was self-monitoring moderate the relationship between various individual (viz., the locus of control and self-esteem) and contextual (viz., top-management openness and trust in supervisor) factors by predicting speaking up behavior in the context of business and management institutions or departments of education universities in Peshawar KPK Pakistan. This research study identifies the possible antecedents that affect the speaking up, which would help to internalize the phenomena of speaking up. This research study would foster the knowledge and understanding of employees about speaking up and would help the organization to adopt better process and programs in order to encourage employeesâ€™ participation. The future studies may investigate the speaking up with including self-assessment and coworker ratings into the study.

Published: August 2018

Background: Complete resolution occurs in many other types of infections with the use of antibiotics but not always with chronic pyogenic osteomyelitis.Objective: The aim of the present study was to evaluate the effectiveness of most conventional method of surgical treatment of chronic pyogenic osteomyelitis by sequestrectomy and saucerisation in Children.Methodology: This present study was a prospective study conducted at Bangabandhu Shekh Mujib Medical University (BSMMU), Dhaka, Bangladesh from January 2015 to December 2016 for a period of two (2) years. Patients aged up to 16 years were included in the study. Purposive sampling was done. Only chronic osteomyelitis of haematogenous origin were included after proper selection of the patients. Sequestrectomy and saucerisation was done. Wound was kept open and allowed to heal from bottom and sides of the wound.Result: A total 36 patients aged up to 16 years were included in the study. Among the cases two third were male 26(72.23%) and rest were female 10(27.77%). The male female ratio was 2.6:1.Therefore the incident was significantly high in males (p<0.01). Most of the patients 28(77.77%) were in 6 to 16 age group, which was significantly high (p<0.01) and mean age was 9.83years. Average time taken for wound healing was 3.75 weeks. Regarding antibiotics, Cap Flucloxacillin was the maximum choice. Patients were followed up to maximum 2 years and evaluated clinically and radiologically. Maximum patients 31(86.10%) had satisfactory (good and fair) outcome, but only 5(13.88%) patients had poor outcome. There was a significant association among sequestrectomy and saucerisation with final outcome (p<0.001).Conclusion: It was concluded that describing operative technique is still method of choice for surgical treatment of chronic haematogenous pyogenic osteomyelitis.Bangladesh Journal of Infectious Diseases 2018;5(1):15-20

Abstract
We use deep Hubble Space Telescope (HST) WFC3/IR imaging to study the initial mass function (IMF) of the ultra-faint dwarf galaxy Coma Berenices (Com Ber). Our observations reach the lowest stellar mass ever probed in a resolved galaxy, with 50% completeness at ∼0.17 M
⊙. Unresolved background galaxies, however, limit our purity below ∼0.23 M
⊙. If modeled with a single power law, we find that the IMF slope is

(68% credible intervals), compared to a Milky Way value of −2.3. For a broken power law, we obtain a low-mass slope of

, a high-mass slope of

, and a break mass of

M
⊙, compared to −1.3, −2.3, and 0.5 M
⊙ for a Kroupa IMF, and for a log-normal IMF model, we obtain values of

M
⊙ for the location parameter and of

for σ (0.22 M
⊙ and 0.57 for the Chabrier system IMF). All three parameterizations produce similar agreement with the data. Our results agree with previous analyses of shallower optical HST data. However, an analysis of similar optical data of other dwarfs finds IMFs significantly more bottom-light than in the Milky Way. These results suggest two, non-mutually exclusive possibilities: that the discrepancy of the dwarf galaxies’ IMF with respect to the Milky Way is at least partly an artifact of using a single-power-law model, and that there is real variance in the IMF at low masses between the currently studied nearby dwarfs, with Com Ber being similar to the Milky Way, but other dwarfs differing significantly.
Validating Forward Modeling and Inversions of Helioseismic Holography Measurements
Authors: DeGrave K. , Braun D. C. , Birch A. C. , Crouch A. D. , Javornik B. 
Published: August 2018

Abstract
Here, we use synthetic data to explore the performance of forward models and inverse methods for helioseismic holography. Specifically, this work presents the first comprehensive test of inverse modeling for flows using lateral-vantage (deep-focus) holography. We derive sensitivity functions in the Born approximation. We then use these sensitivity functions in a series of forward models and inversions of flows from a publicly available magnetohydrodynamic quiet-Sun simulation. The forward travel times computed using the kernels generally compare favorably with measurements obtained by applying holography, in a lateral-vantage configuration, on a 15 hr time series of artificial Dopplergrams extracted from the simulation. Inversions for the horizontal flow components are able to reproduce the flows in the upper 3 Mm of the domain, but are compromised by noise at greater depths.
A Comprehensive Model of the Meteoroid Environment around Mercury
Authors: Pokorný Petr , Sarantos Menelaos , Janches Diego 
Published: August 2018

Abstract
To characterize the meteoroid environment around Mercury and its contribution to the planet’s exosphere, we combined four distinctive sources of meteoroids in the solar system: main-belt asteroids, Jupiter-family comets, Halley-type comets, and Oort Cloud comets. All meteoroid populations are described by currently available dynamical models. We used a recent calibration of the meteoroid influx onto Earth as a constraint for the combined population model on Mercury. We predict vastly different distributions of orbital elements, impact velocities, and directions of arrival for all four meteoroid populations at Mercury. We demonstrate that the most likely model of Mercury’s meteoroid environment—in the sense of agreement with Earth—provides good agreement with previously reported observations of Mercury’s exosphere by the MESSENGER spacecraft and is not highly sensitive to variations of uncertain parameters such as the ratio of these populations at Earth, the size–frequency distribution, and the collisional lifetime of meteoroids. Finally, we provide a fully calibrated model consisting of high-resolution maps of mass influx and surface vaporization rates for different values of Mercury’s true anomaly angle.

Abstract
PDS 70b is a recently discovered and directly imaged exoplanet within the wide (≳40 au) cavity around PDS 70. Ongoing accretion onto the central star suggests that accretion onto PDS 70b may also be ongoing. We present the first high-contrast images at Hα (656 nm) and nearby continuum (643 nm) of PDS 70 utilizing the MagAO system. The combination of these filters allows for the accretion rate of the young planet to be inferred, as hot infalling hydrogen gas will emit strongly at Hα over the optical continuum. We detected a source in Hα at the position of PDS 70b on two sequential nights in 2018 May, for which we establish a false positive probability of <0.1%. We conclude that PDS 70b is a young, actively accreting planet. We utilize the Hα line luminosity to derive a mass accretion rate of

Les shoppers de sites d’achats groupés sont-ils tous des « chasseurs de bonnes affaires » ? Proposition d’une typologie des profils d’achat
Authors: Gonzalez Christine , Korchia Michaël , de Pechpeyrou Pauline 
Published: August 2018

Les sites d’achats groupés ont été accusés de ne présenter que peu d’intérêt sur le long terme pour les prestataires, puisque les acheteurs seraient avant tout des « chasseurs » de bonnes affaires. Les recherches existantes sur les motivations de magasinage apportent une réponse imparfaite à cette assertion car elles ne prennent pas en compte de nouvelles tendances comme le consommateur co-créateur de valeur ou socialement responsable. Plusieurs études terrain mettent en évidence l’existence de sept motivations distinctes, dont la négociation avec les prestataires, ainsi que de cinq profils d’acheteurs.
Preoperative Prediction of the Optimal Toric Intraocular Lens Alignment Meridian
Authors: Chamberlain Paul D. , Montes de Oca Ildamaris , Shah Ravi , Wang Li , Weikert Mitchell P. , Khandelwal Sumitra S. , Al-Mohtaseb Zaina 
Published: August 2018

PURPOSE:
To determine whether any of three keratometry devices is superior to the others in predicting the ideal toric intraocular lens (IOL) alignment meridian.

METHODS:
A retrospective review was performed to identify patients who underwent cataract phacoemulsification with toric IOL implantation from November 2014 to November 2016 at a single academic institution. For each patient, corneal measurements were performed with an optical low-coherence reflectometer/autokeratometer (OLCR), a dual Scheimpflug/Placido analyzer, and a color light-emitting diode (LED) topographer. Postoperatively, the ideal toric IOL alignment meridian that would have resulted in the least amount of residual astigmatism was determined using the online Berdhal & Hardten Toric Results Analyzer (BHTRA). To determine the prediction error, this ideal alignment meridian was compared to the corneal meridian with the highest refractive power, as provided by the three devices.

RESULTS:
Fifty-six eyes of 56 patients were included in the study. The mean absolute errors in the toric IOL alignment meridians of the color LED topographer, dual Scheimpflug/Placido analyzer, and OLCR were 5.2° ± 5.2°, 7.6° ± 5.7°, and 5.4° ± 5.1°, respectively. There was no significant difference in the ability of each device to predict the ideal alignment meridian as determined by the BHTRA.

CONCLUSIONS:
The color LED topographer, dual Scheimpflug/Placido analyzer, and OLCR may all be used to preoperatively determine the best alignment meridian for toric IOL placement. Surgeons should use their best judgment in determining which device to use in preoperative planning for individual patients.

Early Epithelial Remodeling After Standard and Iontophoresis-Assisted Corneal Cross-linking as Evaluated by Spectral-Domain Optical Coherence Tomography
Authors: Atia Raphael , Jouve Lea , Sandali Otman , Laroche Laurent , Borderie Vincent , Bouheraoua Nacim 
Published: August 2018

PURPOSE:
To evaluate and compare epithelial remodeling after standard corneal cross-linking (S-CXL) and iontophoresis-assisted CXL (I-CXL) in eyes with keratoconus by anterior segment optical coherence tomography (AS-OCT).

METHODS:
In this prospective, observational study, AS-OCT and corneal topography were performed before and 1, 3, and 6 months after surgery. Corneal pachymetry was performed and epithelial and stromal thicknesses (central and 16 points on the 6-mm central zone) and the maximum simulated keratometry value (Kmax) were measured.

RESULTS:

Two groups of 30 patients (60 eyes total) with progressive keratoconus underwent S-CXL or I-CXL. Before surgery, both groups of patients presented with an irregular epithelial thickness profile. At 6 months postoperatively, localized corneal epithelial thinning was observed in the superior (
P
= .026), inferior (
P
= .034), inferonasal (
P
= .024), and nasal (
P
= .035) areas at 3 mm and in the superior (
P
= .039), nasal (
P
= .043), and inferior (
P
= .01) areas at 6 mm in the SCXL group. Localized corneal epithelial thinning was observed at 3 (
P
= .04) and 6 (
P
= .01) mm in the inferior area in the I-CXL group. No significant stromal changes were observed for either group. Kmax was stable in both groups at 6 months.

CONCLUSIONS:
Significant epithelial remodeling occurs after S-CXL, resulting in a thinner, more regular thickness profile than after I-CXL. Epithelial thickness profile measurements after I-CXL could be used as an adjunctive follow-up tool for monitoring the efficacy of CXL in progressive keratoconus.

An audit of the screen-and-treat intervention to reduce cryptococcal meningitis in HIV-positive patients with low CD4 count
Authors: Ndayishimiye Egide , Ross Andrew J. 
Published: August 2018

Background: HIV-associated cryptococcal meningitis (CCM) and related mortality may be prevented by the effective implementation of a screen-and-treat intervention. Aim: The aim of this study was to assess the effectiveness of the screen-and-treat intervention at a regional hospital in KwaZulu-Natal province, South Africa. Method: This was a descriptive study in which the records of patients seen in 2015 and 2016 with a CD4 count ≤ 100 cell/mm3 were retrieved from National Health Laboratory Service (NHLS) records and matched against patients admitted for HIV-associated CCM. Results: A total of 5.1% (190 out of 3702) patients with CD4 count ≤ 100 cell/mm3 were cryptococcal antigen positive (CrAg +ve), of whom 22.6% (43 out of 190) were admitted with CCM. Patients who were CrAg +ve had significantly lower CD4 counts (mean CD4 = 38.9 ± 28.5) when compared to CrAg –ve patients (mean CD4 = 49.9 ± 37.4) with p = 0.0001. Only 2.6% (5 out of 190) of patients were referred for a lumbar puncture (LP) as part of the screen-and-treat intervention, whilst 38 who were CrAg +ve self-presented with CCM. Eighty-eight patients were admitted for suspected CCM: eight because of the screen-and-treat-intervention (none of whom had meningitis based on cerebrospinal fluid results) and 80 of whom self-presented and had confirmed CCM. The overall mortality of patients admitted with CCM was 30% (24 out of 80). Conclusion: The current ad-hoc screen-and-treat intervention was ineffective in detecting patients at risk of developing CCM. Systems need to be put in place to ensure that all CrAg +ve patients have an LP to detect subclinical CCM to improve the outcome for those with HIV-associated CCM.

Recently, the Court of Amsterdam decided to ask preliminary questions to the ECJ about EU citizens’ rights of British nationals, anticipating Brexit. However, two weeks later, it allowed an appeal against this decision. It is therefore unclear if and when these questions will be asked.
The effect of postoperative oral antibiotic therapy on the incidence of postoperative endophthalmitis after phacoemulsification surgery in dogs. 320 eyes (1997-2006)
Authors: Corr Amanda T. , Ward Daniel A. 
Published: August 2018

Purpose. To assess the effectiveness of postoperative administration of oral antibiotics at reducing the incidence of endophthalmitis following phacoemulsification cataract extraction in dogs.
Methods. Medical records of the University of Tennessee College of Veterinary Medicine were reviewed for cases having undergone phacoemulsification and divided according to whether or not they had received oral antibiotics postoperatively. Records were then evaluated for a diagnosis of endophthalmitis and incidence rates between the group receiving postoperative oral antibiotics and the group not receiving postoperative oral antibiotics were compared.
Results. A total of 185 patients (320 eyes) were identified by the search. 113 patients (197 eyes) were treated with oral antibiotics postoperatively. 72 patients (123 eyes) were not treated with oral antibiotics postoperatively. Two cases of endophthalmitis were identified, with 1 in each group (P>0.05, Fisher’s exact test).
Conclusions. The overall incidence of endophthalmitis in this study was 0.63%. The rate of postphacoemulsification endophthalmitis was unaffected by the postoperative administration of oral antibiotics.
