Coronavirus et les méfaits de la mondialisation : Etude et analyse

Aujourd’hui le monde assume un coup très dure de la crise pandémique de coronavirus covid-19, ainsi son impact sur l’économie mondiale demeure une source de réflexion pour tous lesintellectuels "académistes, journalistes, professionnels, etc.". De ce fait, en tant que professeurchercheur spécialiste en économie internationale, cette conjoncture a fait bouger ma plume derédaction dont l’ultime objectif est de traiter les retombées de cette crise pandémique surl’économie internationale et bien évidement son impact sur les différents secteurs phares del’économie nationale. Avec cette crise pandémique, toutes les règles néolibérales sont en trainde sauter en Europe comme aux Etats. Nos principaux partenaires (la France, l’Espagne etl’Italie) ont été les premiers après la chine qui ont assumé le coup. Cette interdépendanceéconomique internationale a appliqué solennellement l’effet dominant, d’ailleurs comme toutesles crises qui précèdent. Le Maroc est lié à l’UE par un accord d’association signé en 1996 etest entré en vigueur en l’an 2000. Cet accord prévoyait notamment l’instauration progressived’une zone de libre-échange dont l’ultime objectif est le démantèlement tarifaire sur lesimportations et les exportations. Et depuis la mise en oeuvre d’un statut avancé en 2010 entreles deux partenaires afin de renforcer la relation bilatérale, l’UE demeure le principalfournisseur du Maroc avec une part de 57.1% du total des approvisionnements. Face à la gravitéde la situation, notre premier partenaire avec tous ses Etats membres inonde dans la récessiondepuis les premiers jours de la propagation de virus.Quelles sont les mesures préventives menées par le gouvernement marocain face à cette criseimplacable ? L’UE est en pleine récession, comment le Maroc trouvera une solution pours’approvisionner ? Quelles politiques économiques pourraient remédier les déséquilibresmacroéconomiques ? Face à la vulnérabilité de tissu productif, quelles mesures adéquates poursa mise à niveau? Quelle stratégie pourrait-elle adoptée lors et après le covid-19 ? Cettethématique interpelle bon nombre de questionnements, c’est ce qu’on essaiera de répondre touten analysant la conjoncture de l’économie internationale et marocaine via une étude empirique

Pratiques de La Comptabilité Créative au Maroc : Gouvernance des entreprises et indicateurs de Détection Et De Prévention.

Ce travail vise à répondre à  la question de la relation entre la gouvernance  mesurée par ces compsantes proposées dans la littérature et la comptabilité créative au niveau des entreprises cotées à la Bourse de Casablanca mesurées par les indicateurs proposées par Jones et dechow et kothari? En d'autres termes, le mode de gouvernance peut il être à l'origine de ces pratiques et avoir une influence directe sur ces indicateurs ? Cette étude tente de trouver le lien de causalité entre les différentes variables de la gouvernance et leur impact sur la comptabilité créative. En présentant une analyse exploratoire des paramétre de mesure pour ces deux facteurs puis en vérifiant dans quelle mesure l’analyse de la variance et de la corrélation va confirmer ou infirmer cette hypothèse.Ceux en prenant en considération les indicateurs de détection de la comptabilité créative qui vont être concrétisé par les différents modèles des accruals discrétionnaires  et d’autre part un score de la gouvernance avec une méthode souvent utilisé dans des étude ultérieurs en adoptant une démarche hépitico déductive

Un syndrome malin des neuroleptiques compliqué d’hémorragie méningée et révélant une vascularite cérébrale

Le syndrome malin des neuroleptiques est une complication du traitement par les neuroleptiques. Son incidence est estimée à 0,02% dans la population générale. Le traitement reste symptomatique et repose essentiellement sur l'arrêt immédiat du traitement antérieur. Nous rapportons l'observation clinique d'une patiente de 26 ans, schizophrénique sous Chlorpromazine, se présentant aux urgences pour la prise en charge d'un syndrome malin des neuroleptiques compliqué d'une hémorragie méningée et révélant une vascularite cérébrale

Design of an Analog RFID-Based UHF Band Tag Antenna with Opened Circuited L-shaped Stubs for the Applications in Localization

This paper presents a new analog design of a radio-frequency identification (RFID) tag antenna with a long-read range oriented to localization applications. The actual work focuses on the analog input characterization of antenna impedance by studying the capacitive effect, created by the gaps, and the effect of introduced opened circuited L-shaped stubs, on the RFID tag characteristics. Numerical and measured results confirm that proposed tag antenna performances are significantly improved by introducing gaps and stub structures and after optimizing their dimensions such as length and width. Introduced stubs with optimal dimensions lead to a well level of impedance matching, lower return loss values. Furthermore, two operating frequency bands have been created when the antenna is excited by a 50 Ω port: a low-frequency band around 837 MHz and a higher one around 927 MHz These results have been validated by measured ones. The proposed RFID antenna is mainly composed by three split rectangular resonators (SRR) where introduced structures concern only the larger SRR. The optimized antenna has an area of 76 × 24.6 mm2 and is printed on the Taconic RF-60A substrate with a dielectric constant of 6.12, the thickness of 1.6 mm, and a loss tangent of 0.025. Simulation results show interesting communication performances, of the proposed tag antenna, with a return loss of -22.3 dB around 916 MHz and a long read range up to 25m when it is fed by an industrial Mping M730 chip having a power sensitivity of -24dB and an output impedance Zchip16-j194 (Ω) at 916 MHz

A year of genomic surveillance reveals how the SARS-CoV-2 pandemic unfolded in Africa.

The progression of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic in Africa has so far been heterogeneous, and the full impact is not yet well understood. In this study, we describe the genomic epidemiology using a dataset of 8746 genomes from 33 African countries and two overseas territories. We show that the epidemics in most countries were initiated by importations predominantly from Europe, which diminished after the early introduction of international travel restrictions. As the pandemic progressed, ongoing transmission in many countries and increasing mobility led to the emergence and spread within the continent of many variants of concern and interest, such as B.1.351, B.1.525, A.23.1, and C.1.1. Although distorted by low sampling numbers and blind spots, the findings highlight that Africa must not be left behind in the global pandemic response, otherwise it could become a source for new variants

The evolving SARS-CoV-2 epidemic in Africa: Insights from rapidly expanding genomic surveillance

INTRODUCTION Investment in Africa over the past year with regard to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) sequencing has led to a massive increase in the number of sequences, which, to date, exceeds 100,000 sequences generated to track the pandemic on the continent. These sequences have profoundly affected how public health officials in Africa have navigated the COVID-19 pandemic. RATIONALE We demonstrate how the first 100,000 SARS-CoV-2 sequences from Africa have helped monitor the epidemic on the continent, how genomic surveillance expanded over the course of the pandemic, and how we adapted our sequencing methods to deal with an evolving virus. Finally, we also examine how viral lineages have spread across the continent in a phylogeographic framework to gain insights into the underlying temporal and spatial transmission dynamics for several variants of concern (VOCs). RESULTS Our results indicate that the number of countries in Africa that can sequence the virus within their own borders is growing and that this is coupled with a shorter turnaround time from the time of sampling to sequence submission. Ongoing evolution necessitated the continual updating of primer sets, and, as a result, eight primer sets were designed in tandem with viral evolution and used to ensure effective sequencing of the virus. The pandemic unfolded through multiple waves of infection that were each driven by distinct genetic lineages, with B.1-like ancestral strains associated with the first pandemic wave of infections in 2020. Successive waves on the continent were fueled by different VOCs, with Alpha and Beta cocirculating in distinct spatial patterns during the second wave and Delta and Omicron affecting the whole continent during the third and fourth waves, respectively. Phylogeographic reconstruction points toward distinct differences in viral importation and exportation patterns associated with the Alpha, Beta, Delta, and Omicron variants and subvariants, when considering both Africa versus the rest of the world and viral dissemination within the continent. Our epidemiological and phylogenetic inferences therefore underscore the heterogeneous nature of the pandemic on the continent and highlight key insights and challenges, for instance, recognizing the limitations of low testing proportions. We also highlight the early warning capacity that genomic surveillance in Africa has had for the rest of the world with the detection of new lineages and variants, the most recent being the characterization of various Omicron subvariants. CONCLUSION Sustained investment for diagnostics and genomic surveillance in Africa is needed as the virus continues to evolve. This is important not only to help combat SARS-CoV-2 on the continent but also because it can be used as a platform to help address the many emerging and reemerging infectious disease threats in Africa. In particular, capacity building for local sequencing within countries or within the continent should be prioritized because this is generally associated with shorter turnaround times, providing the most benefit to local public health authorities tasked with pandemic response and mitigation and allowing for the fastest reaction to localized outbreaks. These investments are crucial for pandemic preparedness and response and will serve the health of the continent well into the 21st century
