High-energy Neutrino Emission from Espresso-reaccelerated Ions in Jets of Active Galactic Nuclei
Authors: Mbarek Rostom , Caprioli Damiano , Murase Kohta 
Published: January 2023

Abstract
We present a bottom-up calculation of the flux of ultrahigh-energy cosmic rays (UHECRs) and high-energy neutrinos produced by powerful jets of active galactic nuclei (AGNs). By propagating test particles in 3D relativistic magnetohydrodynamic jet simulations, including a Monte Carlo treatment of sub-grid pitch-angle scattering and attenuation losses due to realistic photon fields, we study the spectrum and composition of the accelerated UHECRs and estimate the amount of neutrinos produced in such sources. We find that UHECRs may not be significantly affected by photodisintegration in AGN jets where the espresso mechanism efficiently accelerates particles, consistent with Auger’s results that favor a heavy composition at the highest energies. Moreover, we present estimates and upper bounds for the flux of high-energy neutrinos expected from AGN jets. In particular, we find that (i) source neutrinos may account for a sizable fraction, or even dominate, the expected flux of cosmogenic neutrinos; (ii) neutrinos from the β-decay of secondary neutrons produced in nucleus photodisintegration end up in the teraelectronvolt to petaelectronvolt band observed by IceCube, but can hardly account for the observed flux; (iii) UHECRs accelerated via the espresso mechanism lead to nearly isotropic neutrino emission, which suggests that nearby radio galaxies may be more promising as potential sources. We discuss our results in light of multimessenger astronomy and current/future neutrino experiments.
Les États du Golfe : nouveaux acteurs de la stabilisation du Sud ?
Authors: Berger Chloé 
Published: January 2023

Depuis la fin des années 2010, les États du Conseil de Coopération de Golfe ont gagné une influence certaine au sein du bassin méditerranéen. Les rapports de force en Méditerranée sont désormais tributaires des rivalités de puissance qui traversent cette région (Iran/CCG ; Qatar/Émirats-Arabie saoudite) longtemps considérée « en marge » du monde arabe. En raison de leurs « singularités », les États du Golfe ont très tôt été poussés à développer des instruments d’influence visant à compenser et dépasser leurs faiblesses naturelles par des effets de levier (alliances avec des partenaires puissants, leadership idéologique, levier du pétrole, assistance au développement et aide humanitaire, etc.). Dans ce contexte, les pétromonarchies ont progressivement investi les champs de la reconstruction et de la stabilisation. Si la différenciation de leurs registres d’influence leur a permis de gagner un rayonnement croissant sur les affaires de la région MENA, elle les a également entraînées dans une concurrence qui pourrait se révéler insoutenable à terme.
Derrière le masque du consensus… Analyse des divergences syndicales autour des enjeux de santé mentale au travail
Authors: Brugière Fabien , Fortino Sabine , Goussard Lucie , Tiffon Guillaume 
Published: January 2023

Cet article questionne le positionnement revendicatif des organisations syndicales de salariés sur les enjeux de santé mentale au travail en mobilisant les principaux résultats d’une enquête sociologique menée, au niveau confédéral, auprès des responsables de la santé au travail et de la formation d’une dizaine de syndicats, ainsi que sur une étude documentaire (documents de congrès, presse syndicale, sites internet). Il montre qu’aussi structurantes que puissent être les lignes de fracture « traditionnelles » instituées sur les enjeux économiques comme l’emploi ou les salaires, ces oppositions s’avèrent peu opérantes pour comprendre les divergences et convergences en matière de santé mentale, aussi bien dans la manière de désigner les facteurs explicatifs de ces risques de santé – notamment le rôle joué par l’organisation du travail et le management – que de nommer les risques eux-mêmes. Ces clivages ressurgissent toutefois nettement concernant la définition des modalités d’action et, surtout, des finalités poursuivies à travers elles. Les positions syndicales s’ordonnent alors selon un continuum allant du projet de convergence avec les employeurs à la nécessité de construire des rapports de force pour obtenir des avancées sur le sujet.
L’accompagnement à l’emploi en temps de dématérialisation
Authors: Codron Emilia 
Published: January 2023

Le service public de l’emploi (SPE) n’échappe pas à la tendance massive à la dématérialisation des services publics. Les prestations d’accompagnement proposées par le SPE, Pôle emploi en tête, passent de plus en plus par des vecteurs numériques. Dans cet article, sont explorées les incidences de cette dématérialisation sur la réception de ces accompagnements par les demandeurs d’emploi les plus éloignés du numérique. Ces derniers en sont insatisfaits et/ou se retrouvent dans l’incapacité de se conformer aux attentes de leurs conseillers. Ils se tournent alors vers d’autres professionnels, en l’occurrence les animateurs du dispositif Mobilisation orientation vers l’emploi qui travaillent dans les quartiers prioritaires marseillais, que nous avons étudiés entre 2016 et 2021.

Published: January 2023

Les échanges commerciaux à la surface du globe ont conduit à l’introduction des espèces végétales et animales dans de nouveaux territoires. En franchissant les barrières écosystémiques (environnementale, reproductive et de dispersion), certaines d’entre elles parviennent à devenir invasives. Spathodea campanulata, mieux connu sous le nom d’arbre tulipe est une espèce originaire d’Afrique introduite à des fins ornementales. C’est une espèce qui représente une grande menace écologique ; elle a envahi les forêts secondaires mésophiles des îles du Pacifique (les îles Cook, Fidji, Polynésie française, Guam, Hawaï, Nouvelle-Calédonie et Vanuatu) mais aussi Porto Rico, le Brésil et l’Australie. En Martinique, l’espèce semble avoir pris une ampleur considérable dans le milieu naturel. Autrefois plantée comme arbre d’ornement, l’espèce s’échappe aujourd’hui des jardins et parcs ornementaux et colonise peu à peu les formations végétales ouvertes. Une étude floristique sur le territoire martiniquais nous a permis de décrypter les principaux traits de vie de Spathodea campanulata.
Mechanical QT and JT intervals by M-mode echocardiography
Authors: Rad Elaheh Malakan , Ilali Hamidreza Mirzaei , Majnoon Mohammad-Taghi , Zeinaloo Aliakbar 
Published: January 2023

Background :
Congenital long QT syndrome (CLQTS) is a life-threatening ion channelopathy leading to syncope and sudden death. Early diagnosis during the prenatal period and timely intervention can prevent sudden cardiac death and catastrophic consequences of this genetic ion channelopathy. Fetal magnetocardiography and fetal electrocardiography (ECG) enable the measurement of fetal QT and JT intervals, but their inherently technically challenging and/or resource-intensiveness nature preclude their routine clinical application. On the other hand, the high-temporal resolution of M-mode echocardiography makes it a well-suited and widely available modality for the measurement of cardiac events.

Aims and Objectives :
We aimed to investigate the mechanical counterparts of the electrical QT and JT intervals on M-mode echocardiographic images of the tricuspid, mitral and aortic valves, and aortic wall.

Methods :
We performed a prospective study on consecutive children referred to the outpatient pediatric cardiology clinic at a tertiary children's hospital. We defined M-mode echocardiographic landmark points on tracings of tricuspid annular planar systolic excursion, mitral and aortic valves, and aortic wall with simultaneous electrocardiographic recording. We measured the mean±SD of the absolute time difference and RR-adjusted time difference in cases with non-coincident ECG events and echocardiographic landmarks.

Results :
Fifty healthy children were enrolled in the study. In 47 (94%) out of the 50 children, Q was coincident with the starting point of the tricuspid annular plane systolic excursion. In all children, the Q was coincident with the mid-point of the A-C line of the mitral valve. In 38 (76%) cases, there was a bump on the anterior wall of the aortic root immediately before the change in the slope of the aortic wall. This was coincident with the Q wave in 100% of cases. In all cases, the J point coincided with the point of acceleration of velocity on TAPSE. In all children, the J point coincided with the initial maximal opening of the aortic cusps. The end of the T wave occurred coincident with the peak of the tricuspid annular planar systolic excursion in 47 children (94%). In 48 children (96%), the end of the T wave coincided with the aortic cusps' closure point.

Conclusions :
Based on our findings, we propose to measure the averaged mechanical QT and JT intervals by using an angled M-mode tracing of the aortic and mitral valve in five consecutive beats in the parasternal long-axis view. This is the first study on mechanical QT and JT intervals in healthy children. The study opens the horizons into the in-utero diagnosis of congenital long QT syndrome by measuring fetal QT and JT intervals using the widely available M-mode echocardiography

Published: January 2023

Introduction :
Preserved congenital heart specimens are an important component of training professionals working with children and adults with congenital heart disease. They are curated in few institutions worldwide and not freely accessible. This was a proof-of-concept project to explore the use of advanced cardiac imaging modalities (computed tomography [CT] and magnetic resonance imaging [MRI]) and virtual reality (VR) simulation to assess the feasibility and identify the best method of imaging curated cardiac pathology specimens.

Methods :
Seven specimens in glass jars with formalin, with varied anatomic lesions, from a curated collection were imaged using MRI and high-dose CT to compare the fidelity of models created via each modality. Three-dimensional (3D) models were created and loaded into a VR headset and viewed in virtual space. Two independent physicians performed a “virtual dissection” and scored the resultant models.

Results :
The highest fidelity and tissue characterization of more delicate structures was achieved with T2 spoiled gradient-echo sequences on MRI (median score of 4 out of 5). CT (median score of 3), while excellent for external anatomy, lost some fidelity with delicate internal anatomy, even at high-radiation doses. No specimens were damaged.

Conclusions :
We believe that in vitro heart specimens can be easily scanned with high fidelity at a relatively low cost, without causing damage, using high-dose CT and MRI. The ability to “walk through” different chambers of the heart makes the understanding of anatomy easy and intuitive. VR and 3D printing are technologies that could be easily adapted to digitize preserved heart specimens, making it globally accessible for teaching and training purposes.

Authors: Siddiq Dr. Abbokar , Al Gamal Ebrahim , AL-Maamari Osamah 
Published: January 2023

Purpose: The study aims to compare the credit risk minimization between Islamic and conventional banks in Yemen.

Approach/Methodology/Design: This paper is limited to a homogeneous sample that includes the Islamic and conventional banks' coverage as they represent the most significant part of the Yemeni banking sector. Using a descriptive-analytical method, data has been collected by a questionnaire sent by post to each Islamic and conventional bank separately located in Yemen's capital city.

Findings: The study concludes that credit risk is the most critical risk facing banks, and there is a significant difference in credit risk minimizing between Islamic.

Originality/value: The result showed that the banks' most critical risks are credit risks, and there is a significant difference in credit risk minimisation between Islamic and conventional banks. Also, conventional banks possessed a credit risk minimizing system better than Islamic banks. Several recommendations identified where the Yemeni banks, whether Islamic or conventional, should use advanced methods to measure and analyze credit risks.

Published: January 2023

Background: Globally obesity rates have more than doubled since 1980 from 5% to 10% in men and 8% to 14% in women. At least 2.8 million people die each year globally, as a result of being overweight or obese. Objective: to study correlation of pulmonary function abnormalities with Serum Lipids and Physical Parameters. Materials & Methods: This was a prospective study done on 40 obese patients during the period from January to December 2012 attending to the Dr. D. Y. Patil Hospital, Mumbai. Results: Obesity is associated with decreased FVC, FEV1, MMEFR, and Restrictive Pattern of PFT. Obese individuals who have undesirable range of hypercholesterolemia tend to have restrictive pattern of pulmonary function test. Undesirable range of hypertriglyceridemia is not associated with any significant abnormality. Body Indices and duration of obesity do not have any significant correlation with lung volumes.
Conclusion: It was concluded that Obesity is associated with decreased forced vital capacity. Body mass index, waist hip ratio and triceps fold thickness do not have any significant correlation with lung volumes.

Prevalence of refractive errors among school children in Wangsa Maju, Kuala Lumpur, Malaysia
Authors: Ismail Lili Asma , Sukumaran Sheiladevi 
Published: January 2023

Background: Uncorrected refractive error is the most common cause of vision impairment and the second leading cause of blindness worldwide. Its prevalence differs among and within countries. This study was aimed at exploring the pattern and prevalence of refractive error among school children in the Wangsa Maju Township, Kuala Lumpur, Malaysia.
Methods: A stratified, multistage, cluster random sampling in a geographically defined area was employed, and 245 school children, aged 8–12 years, from two primary schools in Wangsa Maju Township, Kuala Lumpur, were recruited. The cross-sectional study employed interviewing, measuring uncorrected distance visual acuity (UCDVA) using the Snellen chart, cycloplegic refraction under a streak retinoscope refined subjectively, and a detailed slit-lamp examination to assess the anterior and posterior segments. Myopia, hyperopia, and astigmatism were defined as spherical equivalent (SE) greater than or equal to - 0.50, SE greater than or equal to + 2.00, and cylindrical greater than or equal to 0.75 D, respectively. Reduced UCDVA was defined as an unaided visual acuity < 6/9.
Results: The mean (standard deviation) age of the participants was 10.42 (1.22) years. The overall prevalence of refractive error was 47.8%. Of 245 screened school children, including 42 (35.9%) boys and 75 (64.1%) girls, 117 had refractive error, with a prevalence of refractive error of 17.1% and 30.6% in boys and girls, respectively. Myopia was the most common type (30.2%), followed by astigmatism (16.3%) and hyperopia (1.2%). The prevalence of reduced UCDVA was 36.3% among the screened school children, attributable to refractive error with a significantly high positive correlation (r = +.721; P < 0.01). Among those with refractive errors, sex differences in the magnitude of refractive errors were not statistically significant in the three types of refractive errors (all P > 0.05).
Conclusions: The prevalence of refractive error among primary school children in Wangsa Maju Township, Kuala Lumpur, Malaysia was 47.8%; girls outnumbered boys, but the magnitude of refractive errors showed no sex differences. The prevalence of reduced UCDVA was 36.3%, attributable to refractive error. Irrespective of sex, myopia had the highest prevalence compared to other refractive errors, and its prevalence increased with age. Future population-based studies are required to address the limitations concerning environmental risk factors for refractive error and the impact of ethnic or familial backgrounds on their prevalence in a similar but larger population using the same protocol.

Published: January 2023

Background: Pars plana vitrectomy (PPV) with silicone oil (SO) injection for rhegmatogenous retinal detachment (RRD) repair may adversely affect electroretinographic responses. This study was aimed at assessing retinal function using electrodiagnostic testing after successful PPV with SO tamponade in the eyes with macula-off RRD.
Methods: In this interventional comparative study, eligible participants were recruited prospectively over 1 year. We included the eyes that underwent a single successful three-port PPV with SO tamponade for the primary repair of macula-off RRD. Full-field electroretinogram (ffERG) and multifocal electroretinogram (mfERG) were recorded 1 day before and 3 days after SO removal. The amplitude and implicit time of the a- and b-waves for ffERG and P1 and N1 waves for mfERG were evaluated. The unaffected fellow eyes of the patients were selected as controls.
Results: We included the ten eyes of ten patients (seven men and three women) with a mean (standard deviation) age of 58.8 (6.2) years. The mean (SD) interval between the diagnoses of macula-off RRD and PPV was 11.7 (3.6) days. The mean (SD) duration of SO tamponade was 147.8 (34.9) days. Using ffERG, significantly lower a- and b-wave amplitudes were found in the eyes before and after SO removal or compared to the unaffected fellow eyes (all P < 0.05). Using the mfERG, treated eyes had significantly lower P1 amplitudes in the central R1+R2+R3 rings and in the R4 and-R5 peripheral rings of the macular area in the eyes before and after SO removal or compared to the unaffected fellow eyes (all P < 0.05). The wave implicit time in ffERG and mfERG did not differ significantly in the eyes before and after SO removal or compared to the unaffected fellow eyes (all P > 0.05).
Conclusions: The electrical retinal response density in ERG waveforms increased following SO removal, indicating amelioration of the electrical activity of the retina and macula. These results indicate that the adverse effects of SO tamponade on electroretinography responses may be reversible with removal. In addition, ffERG and mfERG can be used to monitor retinal function in the eyes with macula-off RRD and SO tamponade. Further clinical trials are required to verify the preliminary findings of this study.
Aprendendo com as Experiências Internacionais: Normas Contábeis Diferenciadas para Entidades do Setor Público
Authors: Luz de Lima Raquel , Vaz de Lima Diana , Siqueira Varela Patrícia , Ferreira da Cruz Claudia 
Published: January 2023

Objetivo: Descrever as principais características das experiências de países que realizaram a diferenciação das normas contábeis para entidades do setor público.
Método: Pesquisa documental das experiências internacionais de diferenciação de normas contábeis para entidades do setor público.
Originalidade/Relevância: Não há muitos estudos abordando a diferenciação de normas contábeis no setor público e a adoção integral das IPSAS é frequentemente apontada como um processo dispendioso para as entidades. Portanto, entende-se que ao trazer essa discussão para o âmbito acadêmico e normatizador há a possibilidade de redução dos custos da reforma no setor público, com a adoção de normas de maneira mais uniforme, especialmente nas entidades de pequeno porte, contribuindo para a efetiva harmonização das normas internacionais de contabilidade pública.
Resultados: O desenvolvimento de normas contábeis diferenciadas no setor público é um tema que carece de aprofundamento, pois é necessário que as normas assegurem exigências proporcionais à capacidade administrativa e risco das entidades. Essa diferenciação pode ser operacionalizada de diferentes maneiras e ser realizada em itens de mensuração, reconhecimento e divulgação.
Contribuições Teóricas/Metodológicas: Identificação de países que já adotam normas diferenciadas no setor público, dos tratamentos diferenciados previstos, de critérios utilizados para fins de aplicabilidade dessas normas e de possíveis formas de operacionalização do reporte diferenciado.
Contribuições Sociais/para a Gestão: Espera-se contribuir para as discussões relacionadas ao processo de adoção das IPSAS, tendo em vista que o reporte diferenciado (IPSAS Lite) foi incluído como um dos projetos prioritários pelo IPSASB em 2022.
