Abstract
HO Puppis (HO Pup) was considered as a Be-star candidate based on its γ Cassiopeiae-type light curve, but lacked spectroscopic confirmation. Using distance measured from Gaia Data Release 2 and the spectral-energy-distribution fit on broadband photometry, the Be-star nature of HO Pup is ruled out. Furthermore, based on the 28,700 photometric data points collected from various time-domain surveys and dedicated intensive-monitoring observations, the light curves of HO Pup closely resemble those of IW And-type stars (as pointed out by Kimura et al.), exhibiting characteristics such as a quasi-standstill phase, brightening, and dips. The light curve of HO Pup displays various variability timescales, including brightening cycles ranging from 23 to 61 days, variations with periods between 3.9 days and 50 minutes during the quasi-standstill phase, and a semiregular ∼14 day period for the dip events. We have also collected time-series spectra (with various spectral resolutions), in which Balmer emission lines and other spectral lines expected for an IW And-type star were detected (even though some of these lines were also expected to be present for Be stars). We detect Bowen fluorescence near the brightening phase, and that can be used to discriminate between IW And-type stars and Be stars. Finally, despite only observing for four nights, the polarization variation was detected, indicating that HO Pup has significant intrinsic polarization.

Abstract
Optical depth variations in the Galactic neutral interstellar medium (ISM) with spatial scales from hundreds to thousands of astronomical units have been observed through H i absorption against pulsars and continuum sources, while extremely small structures with spatial scales of tens of astronomical units remain largely unexplored. The nature and formation of such tiny-scale atomic structures (TSAS) need to be better understood. We report a tentative detection of TSAS with a signal-to-noise ratio of 3.2 toward PSR B1557−50 in the second epoch of two Parkes sessions just 0.36 yr apart, which are the closest-spaced spectral observations toward this pulsar. One absorption component showing marginal variations has been identified. Based on the pulsar’s proper motion of 14 mas yr−1 and the component’s kinematic distance of 3.3 kpc, the corresponding characteristic spatial scale is 17 au, which is among the smallest sizes of known TSAS. Assuming a similar line-of-sight (LOS) depth, the tentative TSAS cloud detected here is overdense and overpressured relative to the cold neutral medium (CNM), and can radiatively cool fast enough to be in thermal equilibrium with the ambient environment. We find that turbulence is not sufficient to confine the overpressured TSAS. We explore the LOS elongation that would be required for the tentative TSAS to be at the canonical CNM pressure, and find that it is ∼5000—much larger than filaments observed in the ISM. We see some evidence of line width and temperature variations in the CNM components observed at the two epochs, as predicted by models of TSAS-like cloud formation colliding warm neutral medium flows.

Abstract
Accretion disks and coronae around massive black holes have been studied extensively, and they are known to be coupled. Over a period of 30 yr, however, the X-ray (coronal) flux of Mrk 817 increased by a factor of 40 while its UV (disk) flux remained relatively steady. Recent high-cadence monitoring finds that the X-ray and UV continua in Mrk 817 are also decoupled on timescales of weeks and months. These findings could require mechanical beaming of the innermost accretion flow, and/or an absorber that shields the disk and/or broad line region (BLR) from the X-ray corona. Herein, we report on a 135 ks observation of Mrk 817 obtained with NuSTAR, complemented by simultaneous X-ray coverage via the Neil Gehrels Swift Observatory. The X-ray data strongly prefer a standard relativistic disk reflection model over plausible alternatives. Comparable fits with related models constrain the spin to lie in the range of 0.5 ≤ a ≤ 1, and the viewing angle to lie between 10° ≤ θ ≤ 22° (including 1σ statistical errors and small systematic errors related to differences between the models). The spectra also reveal strong evidence of moderately ionized absorption, similar to but likely less extreme than obscuring events in NGC 5548 and NGC 3783. Archival Swift data suggest that the absorption may be variable. Particularly if the column density of this absorber is higher along the plane of the disk, it may intermittently mask or prevent coupling between the central engine, disk, and BLR in Mrk 817.
L’autorité de la parole
Authors: Viana Thierry 
Published: April 2021

La figure emblématique de l’autorité de la parole comme telle, et non pas comme instrument de l’exercice de l’autorité, est l’« autorité des anciens », que Pascal distingue du « raisonnement » et qu’il limite aux seules connaissances qui dépendent de la mémoire. La forme suprême de « l’autorité des anciens » est celle de l’autorité des prophètes de l’Ancien Testament et des apôtres du Nouveau Testament, qui, prétendant témoigner directement de Dieu, jouiraient de son autorité par délégation. Mais ni la figure emblématique de l’autorité de la parole comme telle, ni la forme suprême de cette figure ne donnent l’essence de cette autorité : son pouvoir d’être écoutée en étant comprise en tant qu’il repose non simplement sur sa propriété d’augmenter la connaissance des choses si la vérité de la parole est sa conformité aux choses, mais sur sa propriété de déceler ce qui est si la vérité originaire de la parole est le caractère ouvert de ce qui est et qu’elle ouvre.
La politique rurale en Algérie à l’épreuve de la territorialisation
Authors: Saidoun Rym , Chehat Fouad , Ait Hammou Sihem 
Published: April 2021

À partir des années 2000, différentes politiques rurales se sont déployées en Algérie faisant référence à un modèle de développement rural territorial, parmi lesquelles la Politique du Renouveau Agricole et Rural (PRAR) et son outil d’intervention : le Projet de Proximité de Développement Rural Intégré (PPDRI). Après plus de cinq années d’exécution, l’article entend analyser la territorialisation des PPDRI à travers un cas d’étude. Sur la base de la littérature théorique, trois mécanismes de territorialisation ont été retenus pour composer notre grille d’analyse. Le processus de mise en place des PPDRI révèle plusieurs distorsions qui font obstacle à la territorialisation des PPDRI. Classification JEL : O18, Q18.
Polémique de la vape et discours d’autorité entre influenceurs et discours institutionnels sur le WEB 2.0
Authors: Vicari Stefano 
Published: April 2021

Le 26 juillet 2019 l’OMS déclare que la cigarette électronique est « incontestablement nocive pour la santé » dans son rapport annuel. Les réactions dans les plateformes 2.0 sont immédiates : acteurs institutionnels, scientifiques et consommateurs prennent la parole pour ou contre la position de l’OMS et les débats se configurent tôt comme une véritable polémique 2.0, mettant en jeu différentes autorités susceptibles d’exprimer une opinion sur la question. Dans cette étude, je me penche sur la construction du discours d’autorité des influenceurs de la vape et sur l’analyse du débat qui s’est déclenché à la suite de la décision de l’OMS dans différentes plateformes du Web 2.0 (Twitter, Facebook et l’espace commentaires des journaux en ligne) dans le but de montrer quelques spécificités de la circulation de l’autorité dans ces espaces numériques et, notamment, que cette polémique repose sur des conflits d’autorité surgissant le long des échanges et la variété des moyens techno-discursifs utilisés par les internautes afin de construire ou déconstruire l’autorité en discours.
L’autorité des jeunes influenceurs du Web dans le genre de l’« unboxing » : un cas d’étude français/italien
Authors: Attruia Francesco 
Published: April 2021

La figure de l’influenceur, attestée en sociologie de la communication dès 1970, a été ramenée sous les feux de l’actualité suite à l’avènement du marketing numérique et des pratiques technodiscursives liées aux médias sociaux tels que YouTube, Instagram, Facebook, etc. L’objectif de cette étude est d’analyser l’autorité dans le genre de l’« unboxing » chez les jeunes influenceurs du Web, qui consiste à déballer et à présenter des produits achetés ou reçus gratuitement par le producteur à des fins promotionnelles. Le corpus bilingue français/italien est constitué de quelques dizaines de transcriptions vidéos hébergées sur YouTube, ayant pour objet la présentation de produits ludiques pour les enfants. En me basant sur les acquis de la psychosociologie de la communication, ainsi que sur les études en rhétorique classique et en philosophie politique, je fais l’hypothèse que le discours des baby-influenceurs relève de trois différentes formes d’autorité : l’autorité du parrèsiaste, métalinguistique et via la fidélisation, associées respectivement à trois instances qui sont autant de rôles énonciatifs dans la pratique de l’unboxing : l’enfant, l’adulte et la communauté d’intérêt constituée essentiellement par le jeune public de la chaîne.
Redéfinir le dirigeant d’entreprise : le retravail de l’ethos collectif dans le discours de remise de diplômes de Faber
Authors: Ly Annelise 
Published: April 2021

Cet article analyse la manière dont Emmanuel Faber, PDG de Danone, redéfinit l’image du dirigeant d’entreprise dans son discours de remise des diplômes à HEC en 2016. Faber fait la promotion de la justice sociale et invite son auditoire à agir pour un monde meilleur. La force de ce discours réside dans la manière dont il construit son message. L’analyse des acteurs sociaux montre la manière dont il fait exister discursivement les petites gens et leur associe un ethos de travailleur, tandis que les autres discours de dirigeants d’entreprise construisent cet ethos de manière passive et péjorative. Cette analyse permet également d’examiner le retravail de l’ethos collectif du dirigeant et d’en comprendre la portée argumentative. Si Faber se conforme à certains stéréotypes, l’étude met en lumière la manière dont il retravaille l’ethos collectif pour le transformer en profondeur et proposer une redéfinition du dirigeant d’entreprise
Hypercoagulability on thromboelastography after living donor hepatectomy—The true side of the coin
Authors: Garg Shankey , Sindwani Gaurav , Garg Neha , Arora Mahesh K , Pamecha Viniyendra , Tempe Deepak 
Published: April 2021

Background and Aims:
Coagulation dynamics after donor hepatectomy are complex. Having complete knowledge of the actual changes in the coagulation status during donor hepatectomy is important to prevent complications such as pulmonary embolism, deep vein thrombosis, and bleeding. Hence, the present study aimed to study the coagulation dynamics following open donor hepatectomy both by thromboelastography (TEG) and conventional coagulation tests (CCT).

Methods:
A total of 50 prospective liver donors were included. TEG and CCT [activated partial thromboplastin time (aPTT), prothrombin time (PT), international normalised ratio (INR), fibrinogen, and platelet counts] were performed for each patient before surgery (baseline), on postoperative day (POD) 0, 1, 2, 3, 5, and 10.

Results:
TEG showed hypercoagulability in 28%, 38%, 30%, 46%, 42%, and 48% patients; in contrast INR showed hypocoagulability in 58%, 63%, 73%, 74%, 20%, and 0% patients on POD 0,1,2,3,5, and 10, respectively. Patients demonstrating hypercoagulability on TEG had significantly decreased reaction time (P = 0.004), significantly increased maximum amplitude (P < 0.001), and alpha angle value (P < 0.001). Postoperatively, INR, PT, and aPTT values increased significantly, while platelets and fibrinogen levels decreased significantly when compared to their baseline values. There was no coagulation-related postoperative complication in any of the patients.

Conclusion:
Hypercoagulability after donor hepatectomy is common. TEG showed hypercoagulability and did not show any hypocoagulability as suggested by the CCT. In patients undergoing donor hepatectomy, CCT may not reflect the actual changes incoagulation status and tests such as TEG should be performed to know the correct nature of changes in coagulation following donor hepatectomy.

Published: April 2021

The study investigated the ameliorative and fecundity potentials of Azanza garckeana on formalin-induced toxicity in mice testes. Male albino mice were divided into eight groups of five mice each. Group I was administered normal saline (1 ml/kg per oral); Group II received formalin (10 mg/kg) alone; Groups III, IV and V received formalin (10 mg/kg IP) plus extract (orally) at 125, 250 and 500 mg/kg respectively for 40 days; Groups VI, VII and VIII received extract alone at 125, 250 and 500 mg/kg respectively. Gonadotropin assays and sperm analysis were carried out using standard methods. Animals in groups III to VIII showed significant body weight increase compared to baseline value (p<0.05) from day 20 to 40. Co-administration of the extract at 250 and 500 mg/kg with formalin caused a significant increase in weight of the epididymis compared to control (p<0.05). Extract at 125 and 500 mg/kg induced significant increase in LH, FSH and testosterone compared to control (p<0.05). Extract alone at 250 and 500 mg/kg caused significant increase in FSH compared with control (p<0.05). Extract at 250 mg/kg demonstrated highest fecundity potential of 8.49. These results imply that Azanza garckeana possesses ameliorative and pro-fertility properties.

Published: April 2021

Staphylococcus aureus is a virulent pathogen that is currently, not only the most common cause of nosocomial infections worldwide, but increasingly also, a community associated pathogen. This study aimed at determining the prevalence and susceptibility of methicillin resistant S. aureus (MRSA) isolated from apparently healthy university student population in Jos Nigeria. Two hundred and seventeen (217) urine samples were screened for Staphylococcus aureus. Isolates were characterized by conventional cultural and biochemical methods including rapid test kits (MicrogenID test kit). Their susceptibility profiles were determined against a panel of eleven antibiotics using the method of the Clinical and Laboratory Standard Institute (CLSI). The MRSA status were confirmed phenotypicallyusing oxacillin and cefoxitin as markers. Of the 217 samples collected, 171 (78.8%) were positive for Staphylococcal species, while 135 of these were coagulase positive and were classed as S. aureus. Seventy-three (73) of these were identified as S. aureus with the MicrogenID test kit. Isolates were resistant to at least one of the antibiotics used in the study. Seventy-one (71) of 73 S. aureus isolates were methicillin resistant. The susceptibility pattern observed in community isolates implies that any outbreak of infections caused by these strains may pose a threat to public health.

Published: April 2021

Background: Studies have shown that hypogonadism is closely related to the development of Type 2 Diabetes. This study aimed to assess hypogonadism among type 2 diabetic and obese male patients in Southwest Nigeria.Methods: One hundred and twenty men consisting of thirty obese diabetics, thirty non-obese diabetics, thirty obese non-diabetics and thirty non-obese non-diabetics, were included in the study. Participants were interviewed to obtain data on biodata, reproductive characteristics, and anthropometry. Venous Blood was collected for the determination of fasting plasma Glucose, glycated haemoglobin, and reproductive hormonal levels.Results: The prevalence of hypogonadism in this study was 20.8%. The mean age of all the participants was 43.39 ± 5.21, most men being in the 40-44 years age group. In this age group, over a third (40%) of the men had low testosterone. Out of the 60 participants who were diabetic, 18 (30%) had low testosterone, two-third of whom (66.7%) were obese. Mean testosterone was significantly lower in obese diabetics when compared with non-obese diabetics. The mean testosterone and FSH were significantly lower in obese non-diabetics as well. Both diabetic and non-diabetic groups had significantly higher estrogen in the obese participants, than in the non-obese.Conclusion: In conclusion, hypogonadism is a common finding among diabetic men, and it occurs in higher frequency with coexisting obesity. Hence, a holistic approach in the treatment of male patients with hypogonadism, type 2 diabetics and obesity should be considered, in order to safeguard their reproductive health.

Objective: This study aimed at determining the prevalence of migraine and tension-type headaches amongst undergraduates of Delta State University (DELSU), Abraka, Delta State, Nigeria and its relationship with academic related-stress.
Methods: A cross-sectional survey among 432 undergraduate students across the eleven Faculties of DELSU, Abraka, Nigeria, using questionnaires to determine the prevalence of migraine headache (MH) and tension-type headache (TTH). The data extrapolated were analyzed with SPSS statistical software (version 20).
Results: MH was shown to have a high prevalence (198, 45.8%) among student of DELSU. Photophobia accompanied most MH episodes more than phonophobia, nausea, vomiting. Similarly, TTH was also very prevalent 237 (54.9%) amongst students of DELSU with females being more vulnerable than male. Spearman's correlation analysis revealed that the prevalence of MH and TTH is strongly associated to student's academic-related activities.
Conclusion: Academic-related stress activities were major predisposing triggers for the prevalence of both headaches.

Crime e castigo: breves notas sobre presídios brasileiros e penas alternativas
Authors: Florêncio Roberto Remígio , Costa Enio Silva da 
Published: April 2021

Os presídios brasileiros são lugares de depósitos de seres humanos, históricos e duplamente marginalizados pela sociedade. O desprezo aos internos do sistema carcerário brasileiro e o preconceito aos egressos desse sistema dificultam o processo de ressocialização e entrada ou retorno ao mundo do trabalho e da dignidade. O presente manuscrito objetiva lançar uma luz sobre as propostas de alternativas às penas de prisão, ao tempo que indica possibilidades de mudanças paradigmáticas em relação aos encarcerados. A metodologia é baseada na revisão bibliográfica e análise documental, tendo como suporte a Legislação Prisional atualizada, observando as normas e os decretos que versam sobre a aplicação de penas alternativas e o sistema educacional dentro dos presídios. Nas conclusões, os autores apontam para a formação de uma consciência humanizada sobre a mercantilização das vidas encarceradas, em relação direta com o processo de educação para a vida, dentro e fora dos presídios brasileiros.
