Published: October 2019

Abstract
We report the discovery of a mid-infrared variable AGN that is hosted by an ultraluminous infrared galaxy (ULIRG) in the Sloan Stripe 82 field. WISE J030654.88+010833.6 is a red, extended galaxy, which we estimate to be at a photometric redshift of 0.28 ≤ z ≤ 0.31, based on its optical and near-infrared spectral energy distribution (SED). The factor of two variability over 8 yr seen in the Wide-field Infrared Survey Explorer (WISE) 3.4 and 4.6 μm wavelength channels is not clearly correlated with optical variability in archival data. Based on our estimation of the physical parameters of the host galaxy, J030654.88+010833.6 is possibly a composite AGN/starburst ULIRG in a phase where high star formation ∼70 M
⊙ yr−1 is occurring. Our estimate of the black hole mass to stellar mass ratio also appears to be consistent with that of broad line AGN in the local universe. The long-term variability of J030654.88+010833.6 as seen in the WISE W1 and W2 light curves is likely due to variations in the accretion rate, with the energy being reprocessed by dust in the vicinity of the AGN.
Magnetic Field Line Twisting by Photospheric Vortices: Energy Storage and Release
Authors: Rappazzo A. F. , Velli M. , Dahlburg R. B. , Einaudi G. 
Published: October 2019

Abstract
We investigate the dynamics of a closed-corona Cartesian reduced magnetohydrodynamic model where photospheric vortices twist the coronal magnetic field lines. We consider two corotating or counterrotating vortices localized at the center of the photospheric plate and, additionally, more corotating vortices that fill the plate entirely. Our investigation is specifically devoted to studying the fully nonlinear stage, after the linear stage during which the vortices create laminar and smoothly twisting flux tubes. Our main goal is to understand the dynamics of the photospheric vortices twisting the field lines of a coronal magnetic configuration permeated by finite-amplitude broadband fluctuations. We find that, depending on the system parameters and the arrangement and handedness of the photospheric vortices, an inverse cascade storing a significant amount of magnetic energy may or may not occur. In the first case, a reservoir of magnetic energy available to large events, such as destabilization of a pre–coronal mass ejection (CME) configuration, develops, while in the second case, the outcome is a turbulent heated corona. Although our geometry is simplified, our simulations are shown to have relevant implications for coronal dynamics and CME initiation.
The Massive Star-forming Regions Omnibus X-ray Catalog, Third Installment

Published: October 2019

Abstract
We offer to the star formation community the third installment of the Massive Star-forming Regions (MSFRs) Omnibus X-ray Catalog (MOXC3), a compilation of X-ray point sources detected in 50 archival Chandra Advanced CCD Imaging Spectrometer observations of 14 Galactic MSFRs and surrounding fields. The MOXC3 MSFRs are NGC 2264, NGC 6193, RCW 108-IR, Aur OB1, DR15, NGC 6231, Berkeley 87, NGC 6357, AFGL 4029, h Per (NGC 869), NGC 281, Onsala 2S, G305, and RCW 49 (Wd 2); they have distances of 0.7–4.2 kpc. Most exhibit clumped or clustered young stellar populations; several contain at least two distinct massive young stellar clusters. The total MOXC3 catalog includes 27,923 X-ray point sources. We take great care to identify even the faintest X-ray point sources across these fields. This allows us to remove this point source light, revealing diffuse X-ray structures that pervade and surround MSFRs, often generated by hot plasmas from massive star feedback. As we found in MOXC1 and MOXC2, diffuse X-ray emission is traceable in all MOXC3 MSFRs; here we perform spectral fitting to investigate the origins of selected diffuse regions. Once again, MOXC3 shows the value of high spatial resolution X-ray studies of MSFRs enabled by Chandra.
The vertebral artery convergence to the cervical spine in elders
Authors: Alicioglu Banu , Gulekon Nadir 
Published: October 2019

Background: In the older population, tortuosity of the vertebral artery (VA), uncovertebral joint (UVJ) osteoarthritis, and abnormal vertebral alignment may alter the normal anatomy.
Aim: We aimed to determine the anatomical variations and relationships between the cervical segment of the VA and the cervical spine with regard to ageing.
Materials and methods: In this retrospective cross-sectional study, the computed tomography angiography scans of 110 subjects were reviewed. Any variations in the VA, UVJ degeneration were identified. The distance between the VA and uncinate process (UP) was measured electronically. The distance between the VA and UP were compared according to the age group (group A > 45, group B = 45-65, and group C > 65 years-old).
Results: With regard to the transverse foramen, 7.2% of the cases had entering abnormalities of the VA, while in one case (0.83%), the right VA had an exiting abnormality (exiting from the C2 instead of the C1). UVJ degeneration was found to be significantly higher in the older age group (p > 0.05). Furthermore, at the C4-C7 levels, the distances between the VA and UP were significantly smaller in the older age group (p > 0.01).
Conclusions: The VA-UP distance has been shown to decrease due to increasing UVJ osteoarthritis in the elderly. The convergence of the VA toward the spine occurs at the most mobile segment of the cervical spine, and this anatomical alteration may predispose temporary and/or permanent vertebral artery occlusion clinically, and be dangerous during cervical spine surgery.

Objective.Serial magnetic resonance imaging (MRI) examinations are often needed in chronic nonbacterial osteomyelitis (CNO) to determine the objective response to treatment. Our objectives in this study were (1) to develop a consensus-based MRI scoring tool for clinical and research use in CNO; and (2) to evaluate interrater reliability and agreement using whole-body (WB)-MRI from children with CNO.Methods.Eleven pediatric radiologists discussed definitions and grading of signal intensity, size of signal abnormality within bone marrow, and associated features on MRI through monthly conference calls and a consensus meeting, using a nominal group technique in July 2017. WB-MRI scans from children with CNO were deidentified for training reading and an interrater reliability study. The reading by each radiologist was conducted in a randomized order. Interrater reliability for abnormal signal and severity were assessed using free-marginal κ statistics.Results.Radiologists reached a consensus on grading CNO-specific MRI findings and on describing bone units based on anatomy. A total of 45 sets of WB-MRI scans, including 4 sets of non-CNO MRI examinations, were selected for the final reading. The mean κ of each category of bones was > 0.7 with majority > 0.9 demonstrating substantial/almost perfect interrater reliability of readings among radiologists. The agreement on signal intensity and the size of signal abnormality within the most commonly affected bones (femur and tibia) were lower than those of other bones.Conclusion.The chronic nonbacterial osteomyelitis magnetic resonance imaging scoring (CROMRIS) tool is a comprehensive standardized scoring tool for MRI in children with CNO. Our interrater study demonstrated good interrater reliability and agreement of readings.
Quand le sport se met au service du management : la fabrique du « salarié de haut-niveau »
Authors: Dalla Pria Yan 
Published: October 2019

À partir de l’étude de séminaires de formation mêlant pratiques sportives et développement personnel, cet article analyse le processus de façonnage par l’entreprise de ses salariés en vue d’optimiser leur épanouissement au travail, source supposée de gains de productivité. Cette approche assimile ainsi l’être humain à un capital optimisable dans lequel il s’agirait d’investir. Elle participe ce faisant de la diffusion d’une morale bioéconomique qui possède un effet dépolitisant et exerce sur ceux qui ne s’y conforment pas des rapports de domination symbolique potentiellement violents.
La cour du roi et les cours des vice-rois : la crise du gouvernement de la monarchie espagnole au XVII e siècle
Authors: Rivero Rodríguez Manuel 
Published: October 2019

Depuis le xix e siècle, la tradition historiographique désigne les années 1640 comme une période de crise de la monarchie espagnole : le moment décisif d’une décadence devenue irrémédiable alors que son empire commence à se disloquer. Ce processus a été interprété comme le résultat de l’échec de la centralisation étatique (caractérisé au contraire par sa réussite en France). Les révolutions au Mexique, en Catalogne, au Portugal, en Sicile et à Naples ont été analysées comme des mouvements périphériques de résistance contre la centralisation promue par le comte-duc d’Olivares. En réalité, la crise a été provoquée par les insuffisances du système vice-royal et par une décentralisation excessive. Elle n’a pas constitué une réaction contre une intervention croissante de Madrid à Mexico, Barcelone, Lisbonne, Palerme et Naples, mais elle s’explique, tout au contraire, par un renoncement. La politique du comte-duc tendait à envisager la Monarchie comme une confédération, mais au sein de cet ensemble les liens étaient si faibles que son projet de vice-royautés, au sens strict du terme, avec une faible tutelle de Madrid, a favorisé l’indépendance du Portugal ainsi que les soulèvements d’autres territoires dans lesquels les sujets revendiquaient la présence du roi et rejetaient celle des mauvais gouvernants qui le représentaient.
Using an Interactive Framework to Assess a Cultural Simulation for Learning: Tag Team Patient Safety Simulation
Authors: Greenawalt Julia A. , Hawkins Paul M. 
Published: October 2019

Background:
The purpose of this pilot study, a replication of a study that originated in Australia for large classroom sizes, was to assess the effect of a culturally sensitive simulation-based pedagogical strategy on student learning.

Method:

This quasi-experimental approach, using a pretest–posttest design with a nonequivalent simulation (
n
= 43) and nonsimulation (
n
= 73) group, mimics an approach called Tag Team Patient Safety Simulation. A scenario was enacted focusing on the cultural needs of Nasifah, a 67-year-old woman requiring home-based palliative care. Challenging conversations were navigated by participants and observers through the engagement of antagonist and cue cards.

Results:
The simulation-based strategy improved student understanding of working with culturally sensitive populations.

Conclusion:

This improvement had no greater learning effect than with the traditional based pedagogical strategy. However, student engagement may have been greater. The need to measure retention, the implications of the findings, the limitations of the study, and directions for future research are discussed.

L’ordre scolaire local des établissements : analyse de différentes formes de travail institutionnel avec les élèves et leurs familles
Authors: Jacobs Marie 
Published: October 2019

Cette contribution s’appuie sur une enquête ethnographique menée dans deux écoles secondaires à Bruxelles. L’étude démontre que, dans un système scolaire hiérarchisé et très inégalitaire, face aux nouvelles problématiques sociales et culturelles présentes dans l’enceinte scolaire, le projet d’établissement se construit nécessairement dans une articulation particulière avec l’environnement local. Ces changements qui affectent le travail institutionnel font émerger de nouvelles formes d’agir professionnel qui s’appuient sur une pluralité de cadres de référence. L’analyse examine plus spécifiquement le rôle de l’éducateur scolaire dans la construction d’un ordre scolaire local avec le quartier et les familles des élèves. La mise en œuvre du projet d’établissement se réalise alors sous deux formes idéal-typiques : l’école éducative, celle qui résiste à son territoire et travaille pour autrui ; et l’école partenaire, celle qui recherche une alliance avec son territoire et lutte contre des formes de travail institutionnel sans autrui.
Phenotypic and genotypic characterization of multidrug-resistant isolates from patients with catheter-associated urinary tract infection in a tertiary care hospital

Published: October 2019

Abstract
INTRODUCTION: Urinary tract infections (UTIs) remain as the most common infection. Catheter-associated (CA) UTI can lead to bacteremia and thereby is the leading cause of morbidity and mortality in hospitalized patients in our country.
AIMS AND OBJECTIVES: This study aims to check the prevalence of CAUTI and study the phenotypic and genotypic characters of the multidrug-resistant organisms in a tertiary care hospital, with special reference to NDM-1 and OXA-23.
MATERIALS AND METHODS: A total of 231 urine samples from patients with CA-UTI in different wards in a tertiary care hospital over a period of 3 months between June and August 2018 were collected and processed following the standard protocol. Antibiotic susceptibility tests were performed by disk-diffusion method. Modified Hodge test (MHT) was done to isolate carbapenem-resistant isolates, and polymerase chain reaction was done to detect NDM-1 and OXA-23.
RESULTS: Out of 231 samples, 101 samples yielded significant growth. These 38 samples were Gram-negative bacilli which were resistant to carbapenems. Out of the 38 which showed carbapenem resistance, 23 were MHT positive. Out of the 23 MHT-positive isolates, 8 (21.05%) were positive for NDM-1 gene and only 1 (2.6%) was positive for the OXA-23 gene.
CONCLUSION: This study has shown that carbapenem-resistant isolates from all the CA urinary tract-infected patients were 52.77% and most of them were Klebsiella. About 21% of them harbored the NDM-1 gene whereas only 2% had the OXA-23 gene. There has been an alarming increase in the spread of carbapenem resistance.
Resveratrol attenuates malathion-induced liver damage by reducing oxidative stress
Authors: Jalili Cyrus , Farzaei Mohammad Hosein , Roshankhah Shiva , Salahshoor Mohammad Reza 
Published: October 2019

Abstract
BACKGROUND: Malathion is an organophosphate insecticide which disrupts the antioxidant system of the body. Resveratrol is a phytoestrogen and antioxidant of the red grape.
AIM AND OBJECTIVE: This study was designed to evaluate the effects of resveratrol against toxic effects of malathion to the liver of rats.
MATERIALS AND METHODS: In this study, 48 male rats were randomly assigned to 8 groups: control normal (saline) and malathion control-treated groups (50 mg/kg), resveratrol groups (2, 8, and 20 mg/kg), and malathion + resveratrol-treated groups (2, 8, and 20 mg/kg). Treatments were administered intraperitoneally daily for 14 days. Griess technique was assessed for determined serum nitrite oxide level. Aspartate aminotransferase, alanine aminotransferase, and alkaline phosphatase concentrations were determined for liver functional disturbances. In addition, thiobarbituric acid reactive species, antioxidant capacity, the diameter of hepatocytes, and the central hepatic vein (CHV) were investigated.
RESULTS: Malathion administration significantly improved liver malondialdehyde (MDA) and nitrite oxide level, the mean diameter of CHV and hepatocyte, and liver enzymes and decreased tissue ferric-reducing ability of plasma (FRAP) level compared to the normal control group (P < 0.01). The resveratrol and resveratrol + malathion treatments at all doses significantly reduced the mean diameter of hepatocyte and CHV, liver enzymes, kidney MDA, and nitrite oxide levels and increased tissue FRAP level compared to the malathion control group (P < 0.01).
CONCLUSION: It seems that resveratrol administration improved liver injury induced by malathion in rats.
Pleural effusion due to Chryseobacterium indologenes: Case report and review of literature
Authors: Arif Nazneen , Khullar Swati , Kumar Ratnesh , Choudhary Shiv Kumar , Kapil Arti , Dhawan Benu 
Published: October 2019

Abstract
Chryseobacterium indologenes is found ubiquitously in the environment; it rarely causes human disease. Hence, we report a case of C. indologenes-associated pleural effusion in a patient with aortic dissection. Postoperatively, the patient developed massive right-sided pleural effusion with underlying consolidated lung. Culture of the pleural fluid yielded pure growth of C. indologenes which was susceptible to cotrimoxazole, minocycline, and tigecycline. Therapy was modified; tigecycline and cotrimoxazole were started following which the patient showed improvement, and subsequent cultures of the pleural fluid were sterile. This report promotes awareness of this organism as an emerging pathogen in lung infections and emphasizes the importance of targeted therapy.
The institutional repository landscape in medical schools and academic health centers: a 2018 snapshot view and analysis
Authors: Kipnis Daniel G. , Palmer Lisa A. , Kubilius Ramune K. 
Published: October 2019

Objective: This study uses survey research methods to gain a deeper understanding of the institutional repository (IR) landscape in medical schools and academic health centers.Methods: Members of the Association of Academic Health Sciences Libraries (AAHSL) were surveyed about their IRs. The authors used a mixed-methods approach of a survey and qualitative content analysis to identify common themes.Results: Survey results indicate that a large majority of responding medical schools and academic health centers have or are implementing an IR (35 out of 50, 70%). Of these, 60% (21 institutions) participate in an institution-wide IR rather than administer their own repositories. Much of the archived content is grey literature that has not already been published, but the percentage of original content varies greatly among institutions. The majority (57.1%) of respondent institutions are not considering an open access policy or mandate. Most institutions (71.4%) reported that repository staff are depositing materials on behalf of users. dSPACE and bepress Digital Commons are the most popular repository platforms in this community. The planned enhancements that were most frequently reported were implementing a discovery layer and ORCID integration. The majority of respondents (54.3%) do not plan to migrate to a different platform in the foreseeable future. Analysis of respondent comments identified the following themes: integration, redundancy, and reporting; alternatives and exploration; uniqueness; participation; and funding and operations.Conclusions: The study results capture a view of the IR landscape in medical schools and academic health centers and help readers understand what services their peers have in place as well as their plans for future developments.

El papel del profesorado y el entorno de aprendizaje en el rendimiento de los estudiantes costarricenses: un análisis a partir de PISA
Authors: Gimenez Gregorio , Barrado Beatriz , Arias Rafael 
Published: October 2019

The role of teachers and the learning environment in academic achievement of Costa Rican students: An analysis from PISAA pesar de que la literatura ha señalado que la calidad del profesorado y el ambiente escolar son factores clave en el rendimiento académico, los estudios que cuantifican empíricamente en qué medida contribuyen al desempeño estudiantil en los países latinoamericanos son escasos. En este artículo, utilizamos datos de PISA-Costa Rica y la técnica de descomposición Shapley-Shorrocks para cuantificar qué porcentaje de la variabilidad de los resultados escolares puede ser explicada por el profesorado y el entorno de aprendizaje. Los resultados muestran que la mayor parte de las diferencias en notas se debe al esfuerzo de cada estudiante (parte no explicada por la función de producción educativa).
Del resto de factores, las características de la escuela y del profesor explican más variabilidad en rendimiento (36% para el promedio de Matemáticas, Lectura y Ciencias) que el efecto conjunto de las circunstancias individuales y familiares (12,5%). Dentro de los factores de escuela, dos elementos tendrían especial relevancia. Por un lado, el comportamiento de los alumnos, destacando los problemas de absentismo e impuntualidad. Por otro, el nivel de autonomía del profesorado y la dirección de la escuela en el diseño de los planes de estudio y las evaluaciones.
Simultaneous excitation of leaky mode resonance and surface plasmon resonance in tilted fiber Bragg grating
Authors: Li Zhihong , Ruan Xiukai , Dai Yuxing 
Published: October 2019

Abstract
This paper presents the first work that theoretically demonstrates simultaneous excitation of both enhanced leaky mode resonance (eLMR) and surface plasmon resonance in ultra-thin Au film coated tilted fiber Bragg grating. The mechanism is discussed by investigating the influence of Au film on mode characteristics of leaky modes and guided modes. A stable transmission spectrum that is only composed of strong dense comb-like eLMR in a wide window is realized. The eLMR excited by metal film exhibits insensitive response to external perturbation, which makes it ideal for tunable devices like optical filters and fiber lasers.
