Two New “Turn-off” Changing-look Active Galactic Nuclei and Implication on “Partially Obscured” AGNs
Authors: Wang J. , Xu D. W. , Wang Y. , Zhang J. B. , Zheng J. , Wei J. Y. 
Published: December 2019

Abstract
We report a spectroscopic identification of two new changing-look active galactic nuclei (CL-AGNs): SDSS J104705.16+544405.8 and SDSS J120447.91+170256.8, both with a “turn-off” type transition from type-1 to type-1.8/1.9. The identification is arrived at through a follow-up spectroscopic observation of the five CL-AGNs candidates that are extracted from the sample recently released in Macleod et al. The candidates are extracted by the authors from the Sloan Digit Sky Survey Data Release 7, and are spectroscopically confirmed quasars with large amplitude variability. By compiling a sample of 26 previously identified CL-AGNs, we confirm the claim by Macleod et al. that CL-AGNs tend to be biased against a low Eddington ratio, and identify an overlap between the CL-AGNs at their dim state and the so-called intermediate-type AGNs. The overlap implies that there two populations of the intermediate-type AGNs with different origins. One is due to the torus orientation effect, and the other to the intrinsic change of the accretion rate of the central supermassive black holes.

Abstract
Using 145 early- and late-type galaxies (ETGs and LTGs) with directly measured supermassive black hole masses, M

relations that are offset by an order of magnitude in the M
BH direction. Here, we searched for substructure in the diagram of M
BH versus central velocity dispersion σ, using our recently published multi-component galaxy decompositions, by investigating divisions based on the presence of a depleted stellar core (major dry merger), a disk (minor wet/dry merger, gas accretion), or a bar (evolved unstable disk). The Sérsic and core-Sérsic galaxies define two distinct relations:

and 0.46 dex, respectively. We also report on the consistency with the slopes and bends in the galaxy luminosity (L)–σ relation due to Sérsic and core-Sérsic ETGs, and LTGs that all have Sérsic light profiles. Two distinct relations (superficially) reappear in the M
BH–σ diagram upon separating galaxies with/without a disk (primarily for the ETG sample), while we find no significant offset between barred and non-barred galaxies, nor between galaxies with/without active galactic nuclei. We also address selection biases purported to affect the scaling relations for dynamically measured M
BH samples. Our new M
BH–σ relations, dependent on morphological type, more precisely estimate M
BH in other galaxies, and hold implications for galaxy/black hole coevolution theories, simulations, feedback, the pursuit of a black-hole fundamental plane, and calibration of virial f-factors for reverberation mapping.
Simples passeurs ou créateurs ? Les dirigeants du sport communiste français face au modèle sportif de l’Est (1923-1991)
Authors: Martinache Igor 
Published: December 2019

Le contexte de « Guerre froide » qui a polarisé une grande partie du monde, mais aussi chacune des sociétés nationales, pendant près de 7 décennies au 20 e siècle n’a pas épargné les activités physiques et sportives en dépit de l’aura d’apolitisme qui les entoure. En France par exemple, la lutte des classes s’est réfractée sur les terrains sportifs dès le début des années 1920 avec la création de la Fédération sportive du travail (FST), affiliée à l’Internationale rouge des sports (IRS) dont le siège était à Moscou. Son remplacement par la Fédération sportive et gymnique du travail (FSGT) en 1934 suite à la réconciliation des deux principales branches, communiste et « réformiste », du mouvement ouvrier s’est aussi traduit par la substitution du mot d’ordre de « sport rouge » par celui de « sport populaire ». L’ouverture internationale, en particulier vers les pays « frères » du Bloc de l’Est ne s’est pas perdue pour autant, et a emprunté des canaux divers : rencontres sportives ponctuelles, tournées d’athlètes et de dirigeants, correspondances à long terme, mais aussi circulation d’idées et de textes doctrinaux. A rebours d’une représentation superficielle présentant la sphère d’influence soviétique et les partis communistes nationaux en son sein comme des ensembles monolithiques et verticaux, cette contribution propose de montrer la réciprocité et la complexité des circulations humaines et idéelles dans la sphère du bloc communiste. À partir de l’analyse comparée des trajectoires biographiques d’un certain nombre de dirigeants du « sport communiste » en France à différentes périodes, nous défendons en particulier la thèse selon laquelle l’évolution des positions diplomatiques et doctrinales des organisations concernées (en particulier la FSGT et le Parti communiste français) ne découlent pas simplement de celles de Moscou, mais présente une certaine autonomie et ont même exercé réciproquement une relative influence vers l’Est. Ce faisant, à partir d’un cas particulier mais paradigmatique, ce texte suggère que les acteurs de l’internationalisation du sport ne se résument pas aux seuls dirigeants des organisations sportives internationales.
« La Fabrique des sports nationaux ». Étudier l’émergence d’une élite du sport Suisse (1860-1930)

Published: December 2019

En Suisse comme ailleurs, les effets et les résonances des activités sportives touchent à la fois aux sphères économiques, politiques, hygiéniques ou culturelles, et l’institutionnalisation du sport est un processus qui permet de comprendre singulièrement des dynamiques structurantes de notre modernité. Tenant compte de cette situation et dans le but de comprendre la place importante prise par le sport dans la société suisse, le projet intitulé « La Fabrique des sports nationaux » – financé pour la période 2019-2023 par le Fonds national suisse pour la recherche scientifique (FNS) – propose de se concentrer sur la genèse et les premiers développements des sports en Suisse de 1860 à 1930. Ce processus d’établissement des principaux sports dans la société helvétique suit plus généralement le développement politique, économique et culturel du pays lui-même dont la structure étatique moderne date de 1848. La recherche porte sur le développement de cinq sports (par ordre alphabétique) : le cyclisme, la gymnastique, le football, le tir, et ce que l’on appelle généralement les « Jeux nationaux » constitués par le hornuss et la lutte suisse. Dans le cadre de cet article, il s’agit de revenir brièvement sur les objectifs de ce projet, puis de développer un aspect central de celui-ci : la recherche extensive engagée autour des élites du sport suisse.

Published: December 2019

<p class="0abstract"><span lang="EN-US">The present work describes the structure of a pilot study which was addressed to test a tool developed to automatically assess Critical Thinking - CT Levels through language analysis techniques. Starting from Wikipedia database and lexical analysis procedures based on n-grams, a new approach aimed at the automatic assessment of the open-ended questions, where CT can be detected, is proposed. Automatic assessment is focused on four CT macro-indicators : basic language skills, relevance, importance and novelty. The pilot study was carried out through different workshops adapted from Crithinkedu � EU Erasmus + Project model aimed at training university teachers in the field of CT. The workshops were designed to support the development of CT teaching practices at higher education level and enhance University Teachers’ CT as well. The two-hour workshops were conducted in two higher educational institutions, the first in the U.S.A (CCRWT Berkeley College NYC, 26 university teachers) and the second in Italy (Inclusive memory project - University Roma Tre, 22 university teachers). After the two workshops, data were collected through an online questionnaire developed and adapted in the framework of the Erasmus + Crithinkedu project. The questionnaire includes both open-ended and multiple choice questions. The results present CT level shown by university teachers and which kind of pedagogical practices they intend to promote after such an experience within their courses. In addition, a comparison between the values inferred by the algorithm and those calculated by domain human expert is offered. Finally, following up activity is shown taking into consideration other sets of macro-indicators: argumentation and critical evaluation.</span></p>

Published: December 2019

Background Relative adrenal insufficiency (RAI) is common in compensated and decompensated chronic liver disease in the presence of sepsis. This study was performed to find out the prevalence of RAI in decompensated cirrhotic patients presenting with hepatic encephalopathy and variceal bleeding without any evidence of infection. Methods The study prospectively included 75 cirrhotic patients with signs of decompensation. The short Synacthen test (SST) was performed on all patients after ruling out infection. Patients with positive blood, urine, sputum, ascitic and pleural fluid cultures or evidence of infection on chest X-ray and those with elevated procalcitonin levels (>0.05 ng/ml) were excluded. RAI in critical illness was defined by a delta cortisol level (difference between basal and post-stimulation cortisol) of ≤9 μg/dl after SST. Results The mean age of the study population was 54 ± 11 years. Upper gastrointestinal bleed and hepatic encephalopathy were seen in 56.6% and 41.5%, respectively, and both were seen in 1.9%. Of the 75 patients, 55 (73%) were in Child-Turcotte-Pugh (CTP) class C and the mean model for end-stage liver disease (MELD) score was 21 ± 7. Forty-five patients (60%) met our criteria for RAI. Those with RAI had lower serum albumin (2.4 ± 0.5 g/dl vs 2.7 ± 0.5 g/dl, p = 0.03) and higher MELD scores (22 ± 7 vs 19 ± 6, p = 0.03). Prevalence of RAI in CTP class C was 65% (36 out of 55 patients) compared to 45% (9 out of 20 patients) in Child-Pugh stage A and B. Similarly, 82% (23 out of 28 patients) with MELD scores >25 had RAI compared to 54% with MELD scores <20. None of biochemical parameters were predictive of RAI on logistic regression analysis. Three-month mortality rate was not significantly different in patients with or without adrenal insufficiency (44% vs 28%, p = 0.11). Conclusion The present study showed RAI to be common in noninfected decompensated cirrhotic patients, but did not predict 3-month mortality. There were no other predictive factors in those with RAI. Hence, in patients with cirrhosis without infection, the clinical utility of routine adrenal function testing needs further elucidation.

Published: December 2019

Background Although there are numerous studies on meningitis and encephalitis separately, literature on meningoencephalitis is sparse. In this study we analysed the clinical profile of meningoencephalitis and its clinical outcome. Methods Fifty adults diagnosed with meningoencephalitis from July 2014 to July 2015 in a tertiary care hospital in South India were studied prospectively and their clinical presentation, aetiology and outcome were analysed. Results Among 50 patients, 33 (66%) were male; 39 (78%) were <50 years of age. Fever was the most common presenting symptom in 41 out of 50 patients (82%), followed by headache (74%) and altered sensorium (62%); only 18 patients (36%) had all three classical symptoms. Twenty-eight out of 50 patients (56%) did not have neck stiffness. A majority of patients had acute-to-subacute clinical presentation. Mycobacterium tuberculosis was identified in 58% (29 out of 50). Forty-seven patients (94%) recovered completely. Conclusion Tuberculosis was the most common cause of meningoencephalitis in the studied population, often with subacute presentation, and outcome was good with early institution of antituberculous therapy.

Published: December 2019

Abstract H1N1 viral infection leads to complications, such as pneumonia, respiratory failure, myocarditis and encephalitis. Spontaneous pneumomediastinum (SPM) is an extremely rare consequence of H1N1 infection and such cases have been sparsely reported. SPM is identified only by a careful clinical examination and obtaining a timely roentgenogram. We report a case of a young male admitted with H1N1 infection complicated by pneumomediastinum. He was treated successfully with oseltamivir, high-flow oxygen and prompt care in the intensive care unit.
Evaluating the Usefulness and Utility of a Webinar as a Platform to Educate Students on a Uk Clinical Academic Programme
Authors: Nadama Hauwa'u Hayat , Tennyson Maria , Khajuria Ankur 
Published: December 2019

Background The Academic Foundation Programme (AFP) is the first step of the UK's national integrated clinical academic pathway; however, the application process can be unclear. We evaluated webinars as a teaching medium to enhance knowledge and confidence of prospective applicants. Methods Medical students were invited to attend a free webinar. The webinar was designed by a former academic foundation trainee, outlining the UK integrated clinical academic pathway and how to apply to the AFP. An online questionnaire-based cross-sectional study was conducted pre- and post-webinar. Results In total, 118 out of 199 (59.3% response rate) attendees filled out the pre-webinar questionnaire, while 64 out of 199 attendees (32.2% response rate) filled out the post-webinar questionnaire. Of these 83.1% had never previously attended a medical education webinar, and 92.3% agreed webinars offer flexibility and convenience, saving time and money on travel. Matched pre- and post-webinar data showed an increase in participants’ knowledge (p < 0.0001) and confidence (p < 0.001). Conclusions This study has demonstrated the utility of a focused webinar in enhancing medical students’ knowledge and confidence in AFP applications. Webinars are a rarely utilised yet highly acceptable way to engage millennial students and could be used to enhance engagement with clinical academia.

Published: December 2019

IntroductionTo investigate and compare the effect of the multimodal approach of electrotherapy and myofascial release on pain, range of motion, and functional restriction in patients with chronic mechanical neck pain.MethodsOverall, 60 patients of both genders, aged 18–40 years, with chronic mechanical neck pain were diagnosed by an orthopaedist in Shoubra General Hospital, Cairo, Egypt. They were randomly assigned into 3 groups. In group A, 20 patients received multimodal approach of electrotherapy (low level laser therapy, interferential therapy, ultrasound, and non-guideline approach in the form of stretch and strength) 3 times a week for 4 weeks. In group B, 20 patients received myofascial release therapy and non-guideline approach in the form of stretch and strength 3 times a week for 4 weeks. In group C, 20 patients received traditional therapeutic exercises in the form of stretch and strength 3 times a week for 4 weeks. All patients in all groups were evaluated pre- and post-treatment through visual analogue scale, cervical range of motion (CROM) device, and neck disability index to assess pain, CROM, and functional restriction.ResultsMultiple pairwise comparison tests (post-hoc tests) revealed that there was no significant difference between the effect of multimodal approach of electrotherapy (group A) and myofascial release therapy (group B) on pain intensity level, CROM, or functional restriction. However, these turned out significantly more effective than traditional therapeutic exercises (group C).ConclusionsBoth multimodal approach of electrotherapy and myofascial release therapy are effective in treating patients with chronic mechanical neck pain.
The Political Economy of New Media: Challenges and Opportunities Across Democracies and Autocracies
Authors: Sobbrio Francesco 
Published: December 2019

Abstract
There are several open research questions in the political economy of new media. What role do they play in the spread of &#x93;fake news&#x94;? What are their effects on voters’ beliefs and behavior, and on the overall level of ideological polarization? What is their impact on citizens’ trust in experts and democratic institutions? Furthermore, we still need to fully understand to what extent new media and digital platforms represent tools to overthrow autocracies or, rather, whether they provide new propaganda and surveillance instruments for such regimes.
Le XXIe siècle ou la séparation achevée. Éthique et technologie dans Anima Motrix d’Arno Bertina
Authors: Jeusette Julien 
Published: December 2019

De Warburg à Agamben en passant notamment par Debord et Baudrillard, nombreux sont les intellectuels qui ont alerté leurs contemporains sur les risques de la technologie : celle-ci nous séparerait les uns des autres et nous mettrait à distance du monde. Or, il est évident qu’au XXIe siècle, cette séparation prend une tournure plus dramatique. Nous suggérons ici qu’Anima Motrix, le roman d’Arno Bertina paru en 2006, permet de mieux comprendre les dangers de l’emprise des dispositifs sur nos vies ; à partir d’un cas extrême, l’écrivain nous invite à penser le potentiel inhumain de notre temps.
Evaluation of Impact of Some Selected Plants on Haematological Parameters of Testosterone and Estradiol Induced Benign Prostatic Hyperplasia Adult Male Rats
Authors: Ugwu Melvin Nnaemeka , Agbor Asuk Atamgba , Ubana Eteng Mbeh , Odey Emuru Edward 
Published: December 2019

Background: Benign prostate hyperplasia (BPH) is an age-related disease of unknown etiology, characterized by prostate enlargement. The effect of Prosopis africana (PA), Vernonia amydalina (VA) and Ocimum gratissmum (OG), plant extracts on haematological parameters of BPH animal model was investigated.
Methods: BPH was induced in 45 male Wistar rats (250-350 g) by exogenous injection of testosterone and estradiol in staggered doses for 3 weeks. To confirm BPH induction, some animals were sacrificed; histological inspection of prostate gland and PSA was carried out. Forty BPH induced rats were divided into 8 groups. Group 1 and 2, 3 and 4, 5 and 6 were treated with 50 mg/kg bw and 100 mg/kg bw doses of PA, VA and OG extracts respectively. Group 7 received finasteride (0.1 mg/kg bw). Group 8 BPH control and five rats without induction constitute group 9, the normal control and both received distilled water. After 45 days, the rats were anaesthetised by a brief exposure to trichloromethane vapour and 5 ml of blood was collected from the rats through cardiac puncture and dispensed into well-labelled EDTA containers to avoid coagulation. All analyses were completed within 24 h of sample collection.
Results: Results showed that induction of BPH caused a significant (P< 0.05) enlargement of prostate gland when compared to normal control. All extracts produced significant (P<0.05) reduction in the weight of the enlarged prostate when compared to the BPH control. There were significant (P ˂0.05) decline in RBC, PCV and Hb of BPH control when compared to the normal control and treated groups. In the treated groups the administration of the extracts and standard drug exhibited an increase in RBC, PCV and Hb concentration when compared with the BPH control. Also there was significant (P < 0.05) increase in the WBC, neutrophils, platelets, monocytes, lymphocytes and eosinophils levels in BPH control when compared to normal control and treated groups. In all treated groups there was significant decrease in WBC, neutrophils, platelets, monocytes, lymphocytes and eosinophils concentration levels when compared with the BPH control group.
Conclusion: The result of this study indicates that the extracts have the potential to reverse the inflammation caused by BPH and also have the capacity to boost the numbers of red blood cells probably by inhibiting the hemolysis caused by inflammatory factors or by enhancing the production of red blood cell from the bone marrow.
