Tackling the Economic Challenges of COVID-19: A Look at the Federal Reserve System
Authors: Dutta Amitabh S. , Kulkarni Kishore , Lai Kun Peng
Published: February 2022

In this paper, we take a look at some of the measures taken by the central bank of the United States viz. the Federal Reserve System, to help businesses, both small and large, to weather the unprecedented economic challenges faced by managers and owners of businesses to survive through the crisis of shutdowns, lost sales, unemployment, and illness. One such step taken by the Federal Reserve was to lower the discount rate, the rate at which Federal Reserve gives loans (Discounts and Advances) to U.S. financial institutions.  It may be taken as a standard response to economic slowdowns by central banks around the globe, but Federal Reserve's action has more significant effects than any other central bank.
While there is no "one size fits all" economic measure that works in all countries in the wake of the pandemic, we believe that knowing and discussing what one central bank did – can lead to bankers, academics, politicians, business managers and owners from different countries share their experiences and tailor proposals and plans to fit the needs of an individual country. In this spirit, this proposed paper is an endeavor to examine the role of monetary policy in averting the forces of the pandemic.  The paper is divided into three sections.  Section 1 talks about the structure of the Federal Reserve System, surveys some historical behavior and examines the decision-making process in the system.  Section 2 discusses the economic impacts of coronavirus on all economic aspects but focuses more on the monetary structure of the US economy.  Section 3 makes the argument that expansionary monetary policy was a tremendous necessity of the time, but overdoing its activity in the same direction may bring back the threat of inflation.  Summary and conclusion follow Section 3.
Forced Migration of Rohingya Refugees from Myanmar to Neighboring Countries
Authors: Fahim Md. Hasnath Kabir
Published: February 2022

In this current world, the Rohingya Muslims of Myanmar are deemed to be one of the most inhumanly tortured minorities. The culture of racial persecution is indulged by the decades of a clash between the Myanmar Government and the Rohingyas regarding religious and ethnic variance. However, it is also argued that the Rohingya crisis is not confined to religion but comprises economic and political issues equally. Rohingyas have been deprived of their basic human rights and faced a security crisis. Mass killing, rape, and inhuman torture are notable in this regard. Methodical abuse of human rights of the Rohingya by the military junta of Myanmar has forced thousands of Rohingya to flee the country. Consequently, thousands of Rohingyas now reside as refugees, mostly in Bangladesh, while others escaped to Malaysia, Singapore, and the Middle East. The Government of Myanmar has denied the citizenship of Rohingyas and labeled them as foreigners. This paper highlights the measures adopted by the global community for preventing the mass killing of Rohingyas. This research also portrays the means and methods of the Myanmar Government to suppress the Rohingyas. Furthermore, this paper looks into all sorts of violations of human rights and humanitarian disasters suffered by the Rohingyas and the subsequent humanitarian aid received from the regional and international community.

USING THE SUSTAINABILITY-BALANCED SCORECARD FOR ASSESSING SUSTAINABILITY ISSUES OF THE GREEN ENERGY COMPANIES
Authors: Lu Ming-Tsang , Chang Shih-Chia , Huang Li-Hua
Published: February 2022

Assessing the sustainability issues of the green energy companies is a multiple criterion decision that includes both quantitative and qualitative elements. The sustainability-balanced scorecard (SBSC) for sustainability evaluation is more difficult than an internal evaluation and it requires more serious investigation in the green energy companies. This paper objectives to mix this sustainability evaluation and use fuzzy information with the SBSC. The study presents a fuzzy DEMATEL (decision-making trial and evaluation laboratory) method to develop an assessment model that integrates triangular fuzzy numbers, and DEMATEL to develop a fuzzy assessment, which prioritizes the relative influence of SBSC for green energy companies’ elements. First, this paper conducts a literature review on SBSC regarding sustainability issues to generate 15 elements with five aspects, which are used to measure the sustainability assessment. Next, fuzzy DEMATEL is employed to manage the uncertain linguistic terms, then to set up an influential network relationship map (INRM). This suggested model provides a structure for the related green energy companies to select the evaluation method and could arrange the sustainability approach according to future competitive pressure. The result shows that environmental aspect is the most direct effect and social aspect is the most important effect aspect to the other aspects.
Adapter les territoires au risque d’inondation en France et en Espagne : vers de nouvelles pratiques d’aménagement des zones inondables ?
Authors: Rode Sylvain , Ribas Palom Anna , Saurí David , Olcina Cantos Jorge
Published: February 2022

L’injonction actuelle à l’adaptation des territoires au changement climatique et à ses effets ne contribue-t-elle pas à l’émergence de nouvelles formes d’aménagement des zones exposées au risque d’inondation par débordement de cours d’eau ou submersion marine, via le développement de nouvelles pratiques opérationnelles visant à aménager avec l’inondabilité et l’eau ? Cette question est examinée grâce à une analyse comparée des politiques d’aménagement des zones inondables aujourd’hui mises en œuvre en France et en Espagne. En France, de nouvelles formes d’action publique voient le jour (au moins ponctuellement) afin de favoriser la résilience des territoires à l’inondation et leur adaptation aux conséquences du changement climatique. Les opérations d’urbanisme résilient et les acquisitions/démolitions de biens en zone à risque constituent deux manifestations de l’appropriation progressive de cette nouvelle logique par les acteurs de l’aménagement des territoires locaux. À l’inverse en Espagne, les initiatives s’inscrivant dans la logique du « faire avec » le risque d’inondation apparaissent bien plus embryonnaires. Toutefois, cette nouvelle perspective et les formes d’aménagement qui lui sont associées commencent à être mises en débat suite à de récents aléas naturels qui ne manquent pas de questionner les modes d’aménagement qui ont été privilégiés jusqu’à présent, en même temps qu’apparaissent des actions qui, promues par les collectivités territoriales, s’engagent pour un aménagement urbain plus résilient face au risque d’inondation.
Accès aux services publics : l’action de l’État, des Caf et des opérateurs publics pour l’inclusion numérique
Authors: Kesteman Nadia
Published: February 2022

Depuis le début des années 2000, l’État a engagé une réforme continue en faveur de l’administration numérique. Le projet Copernic lancé en 2004 marque le début de l’administration électronique. Dernier en date des projets concernant l’administration numérique, le programme Action publique 2022, d’octobre 2017, poursuit plusieurs objectifs de réforme dont la simplification et l’amélioration de la qualité des services publics, via notamment la transformation numérique de l’administration. La France est aujourd’hui bien classée en matière d’administration numérique et l’objectif, au-delà de la simplification des démarches en ligne et de l’ergonomie des sites, est d’accompagner les publics éloignés du numérique et/ou des démarches administratives.
« Le ministre des Impôts prélève aussi des idées, bien plus que des impôts ». Deux prix de livres d’économie sous le « haut patronage du ministère de l’Économie et des Finances »
Authors: Chahsiche Jean-Michel
Published: February 2022

Depuis les années 2000, Bercy s’est engagé dans une politique de pédagogie économique réunissant des acteurs multiples, publics, privés et associatifs. L’une des manifestations de cette politique est « le haut patronage du ministère de l’Économie et des finances » accordé à deux instances de consécration des livres d’économie : le Prix du livre d’économie, organisé par l’association Lire la société, proche des élites politico-administratives et de la presse économique, et le Prix Turgot du meilleur livre d’économie financière, remis par un think tank proche des élites financières, le Cercle Turgot. Au travers de l’étude de leur environnement institutionnel (les entreprises et institutions publiques partenaires) et de la prosopographie de leurs acteurs (organisateurs, jurés et lauréats), cette recherche interroge une forme particulière de rapport entre pouvoir temporel et pouvoir spirituel sur l’économie. On montre ainsi que les deux prix fonctionnent comme des instances de captation et de contrôle de ressources dont les jurés et organisateurs sont relativement dépourvus : les titres de légitimité intellectuelle et scientifique, positions académiques et d’expertise, et la notoriété médiatique des auteurs distinguent ces derniers de ceux qui les consacrent. Si ce différentiel trahit l’hétéronomie du travail de consécration, confié à des agents et institutions dépourvus de légitimité dans les sphères de production des savoirs économiques, notre enquête montre que la fonction de consécration se double d’une fonction latente de socialisation entre élites économiques, intellectuelles et médiatiques, et d’une fonction idéologique de promotion du libéralisme économique, qui bénéficie du « haut patronage de Bercy ».

Quelles éthiques pour la télévision ? Dignité humaine et préjudices
Authors: Jost François
Published: February 2022

Ce texte pose au départ la pluralité des éthiques possibles et se fixe comme objectif de débusquer celles qui sont mobilisées, implicitement le plus souvent, aussi bien par les institutions de régulation, les codes de déontologie que par les téléspectateurs. Une première distinction est opérée entre éthique et déontologie. Si celle-ci dicte des devoirs professionnels, elle n’épuise pas le champ de l’interrogation morale, délaissant notamment les problèmes posés par l’éditorialisation des informations. Dans un deuxième temps est examiné, à partir de quelques décisions du CSA, ce qui, pour cette institution, constitue une faute morale. La dignité humaine y joue un rôle majeur balayant la question du consentement qui, comme le note Ruwen Ogien, est pourtant à la base de la plupart des éthiques. Poursuivant dans le sillage du philosophe, François Jost s’interroge sur la notion d’offense qui revient constamment dans l’actualité et la différencie de celle de préjudice. Ces réflexions s’appuient sur l’analyse de cas de divertissements condamnés moralement par l’institution de régulation. Que devient le principe de non-nuisance quand on l’exporte du terrain des divertissements à celui de l’information ? Le texte répond à cette dernière question en traçant les contours d’une éthique du regard qui prenne en compte, plus qu’aujourd’hui, celui ou celle qui est visé par l’objectif, le spectrum , (Barthes), tandis qu’il passe de vie à trépas. Comme le travelling selon Rivette, cette représentation de la mort est « une affaire de morale ».
L’éducation sexuelle à la télévision française. L’exemple de « L’amour en questions »
Authors: Ozil Didier
Published: February 2022

En 1994, la nouvelle chaîne La Cinquième propose un programme original d’éducation sexuelle destiné, principalement, aux adolescents. Ce programme présente une certaine vision de la sexualité humaine, à la fois médicale, voire quasi anatomique, mais également sociétale : entre conseils de médecins, illustrations graphiques décalées et analyse des modes de vie. La difficulté de cette série documentaire sera double : veiller à produire un discours ouvert, non normatif et, d’autre part, séduire une cible adolescente par une proposition formelle novatrice. Tout cela en se tenant dans la droite ligne de la chaîne du savoir, adossée à sur une éthique de programmation basée sur le partage et de mise à disposition des connaissances. En sa qualité d’émission éducative, l’Amour en Questions reste l’un des rares programmes à avoir tenté ce pari, proposer une approche de la sexualité en direction d’un public jeune, sur un médium massif et peu interactif.
SNCF Réseau se mobilise pour accompagner les projets de RER métropolitains

Développer les RER métropolitains et les intégrer au réseau ferré national répond à deux objectifs majeurs : d’une part, satisfaire les besoins des Français en termes de mobilité, et d’autre part développer la part de marché du ferroviaire dans le cadre de l’action climatique (réduction globale des émissions de gaz à effet de serre). Le chemin de fer, économe en espace et en énergie et respectueux de l’environnement, est une colonne vertébrale des offres de transport que les grandes agglomérations mettront en place à l’avenir.
The Source of Purchased Medications and Its Impact on Medication Mistakes and Hospitalizations
Authors: Coates Martha C. , Granche Janeway , Sefcik Justine S. , DiMaria-Ghalili Rose Ann
Published: February 2022

Older adults self-administer prescribed medication regimens to treat chronic diseases, which can lead to mismanagement, medication-related harm, and hospitalization. Using the National Health and Aging Trends Study (NHATS) dataset, we examined the extent to which the medication source could impact the occurrence of self-reported medication mistakes and hospitalizations in community-dwelling adults aged ≥65 years who managed medications independently (
N
= 3,899). The majority (65%) picked up medications, 18% had medications delivered, and 17% used both methods. Compared to those picking up their medications, those using delivery only were less likely to have a hospital stay (odds ratio [OR] = 0.61, 95% confidence interval [CI] [0.51, 0.94]) but had no difference in odds of medication mistakes (OR = 1.13, 95% CI [0.57, 2.23]). Those using both methods were more likely to report hospital stays (OR = 1.43, 95% CI [1.11, 1.85]) and medication mistakes (OR = 1.65, 95% CI [1.00, 2.73]). Health care providers should consider medication source when assessing older adults' ability to safely self-manage medications. [

Factors influencing chronic semi-arid headwater stream impairments: a southern California case study
Authors: Alford Jennifer B , Mora Jose A
Published: February 2022

Sources of stream impairments are well known; however, less attention has centered on characterizing the extent to which human-environmental factors influence headwater stream quality within semi-arid watersheds. This study quantified the extent to which seasonal weather patterns and landscape attributes contribute to the physicochemical characteristics of two perennial headwater tributaries and their confluence within the semi-arid mountainous region of the Santa Ana River Basin, California. In situ sampling of stream temperature (℃), stream flow rate (m/s), nitrate (NO3-), ammonium (NH4+), turbidity (NTU), dissolved oxygen (DO), conductivity, pH and lab assessments for. E. coli, total coliform (TC) and total dissolved solids (TDS) occurred during dry and wet season conditions. Across sampling locations, multiple parameters (i.e. NO3-, NH4+, TDS, TC) consistently exceeded regulatory standards simultaneously during both the dry and wet seasons, however, the level of concentrations varied between a tributary catchment landscape with high percentage of impervious surfaces (i.e. roads, buildings) and wastewater infrastructure (i.e septic, sewer) versus one characterized by agricultural activities (i.e. crop, livestock) and barren land. Findings illustrate the need for hydrologically comprehensive strategies (i.e. stream headwaters to river mouth) that are community to agency-driven and that support the expansion of monitoring and shared knowledge to mitigate impairments within headwater streams and downstream. Potential avenues for community collaborations that support sustainable water management strategies are highlighted.
Geographical scattering in Italian inner areas, politics and COVID-19
Authors: Falco Stefano De ,   Department of Political Sciences, University Federico II of Naples, Italy, Via L. Rodinò 22, 80138 Naples, Italy, Fiorentino Giulia
Published: February 2022

In recent months, the COVID-19 pandemic has been fervently considered from the perspective of various disciplines in the scientific community. Many of the proposed approaches are tied to reflections on the imminent and future effects of the pandemic. This contribution begins with a study of the recent past in Italy, analyzing the hurdles in politics that came to light due to the wave of COVID-19 infections worldwide. Particularly, the research considers the criticality of the geographical scale of reference in Italy's political actions. COVID-19 induced a need for the government to interact with people locally, especially through small municipalities in geographically central, inner areas, is emphasized. The main aim of this research is to attribute to this specific COVID-19 disaster the instrumental role of turning on the lights on the need to intervene in the inner areas of Italy, often very neglected. So the focus of the work is on inner areas and the probable catalysis of the political management dynamics that concern them, as an effect of the COVID's impacts. The pandemic is, therefore, only the contingent phenomenon which, in this case, can perhaps accelerate political interventions in inner areas. To explain the reason for this, we show how the vulnerability of inner areas, already generally risky, has become one of the weak links in the chain of protection from COVID-19 in terms of a geographical scattering phenomenon.
Application of Standardization for Causal Inference in Observational Studies: A Step-by-step Tutorial for Analysis Using R Software
Authors: Lee Sangwon , Lee Woojoo
Published: February 2022

Epidemiological studies typically examine the causal effect of exposure on a health outcome. Standardization is one of the most straightforward methods for estimating causal estimands. However, compared to inverse probability weighting, there is a lack of user-centric explanations for implementing standardization to estimate causal estimands. This paper explains the standardization method using basic R functions only and how it is linked to the R package stdReg, which can be used to implement the same procedure. We provide a step-by-step tutorial for estimating causal risk differences, causal risk ratios, and causal odds ratios based on standardization. We also discuss how to carry out subgroup analysis in detail.

La redécouverte de Jean Epstein ou la construction d’un mythe : questions de méthode et de perspective
Authors: Mortari Virgilio
Published: February 2022

Depuis une vingtaine d’années on assiste à une redécouverte d’Epstein qui culmine avec l’édition de ses Écrits complets. Ce retour d’intérêt pourrait être hautement salutaire sinon nécessaire, non seulement pour les études epsteiniennes – qui restaient sans doute insuffisantes –, mais pour la critique et l’histoire du cinéma et celle de l’art, voire de la société contemporaine. Il pourrait être, pour employer une formule d’Adorno, l’occasion de faire de la « critique sociale » par le biais de la « critique artistique ». Si la présente étude se veut polémique, elle n’a pas l’intention de relever les thèses qui peuvent paraître discutables ici ou là : les contributions des différents artisans de la redécouverte epsteinienne nous semblent, dans leur ensemble, admirables dans leurs efforts de trouver des relations nouvelles, des appuis utiles, des perspectives encore insoupçonnées, offrant un assortiment de points d’appui auxquels on a tenté de s’accrocher pour ouvrir des portes qui, espère-t-on, donneront accès à cette terra incognita. Cependant il est apparu que cette redécouverte repose la plupart du temps sur des présupposés historiographiques et sociologiques concernant le « modernisme » et « l’avant-garde » considérés comme allant de soi. C’est à une remise en question de ces présupposés – qui dépassent le simple champ des études epsteiniennes – que nous voulons procéder. On se demandera, en somme, si l’orientation générale de la redécouverte epsteinienne n’a pas abouti à déformer l’œuvre de son héros ; si elle ne consiste pas en une opération mythologique et apologétique, la tentative de trouver incarnées en une idole encore vierge, les valeurs qui, quotidiennement et pratiquement, nous échappent et auxquelles nous sommes inlassablement incités à croire – ne serait-ce que par procuration –, celles d’une liberté que nous sommes encore trop enclins à trouver dans la rhétorique idéaliste, sinon dans un vague mysticisme.
Race and military coalitions in the Middle Niger during the second half of the 19th century
Authors: Bradshaw Joseph M.
Published: February 2022

In the latter half of the 19th century Futanke invaders and their allies toppled the Caliphate of Ḥamdallāhi. The Futanke and the Masinanke of Ḥamdallāhi shared a similar faith, language, and culture, and both had fought wars under the umbrella of jihad against non-Muslims and Muslims whose practice they considered unorthodox. Despite the anti-“pagan” rhetoric Futanke and Masinanke leaders often directed against people they called “black,” the instability of wars in the period from 1861 to 1890 necessitated the building of alliances that diminished the instrumental value of racial and religious exclusion. By accommodating non-Muslim allies, the Futanke built a strong coalition that eventually defeated their Muslim Fulbe enemies.
Quand le droit pense la politique : à propos de deux lettres d’al-Muḫtār al-Ṣaġīr al-Kuntī (m. 1847) à l’imam de Ḥamdallāhi
Authors: Warscheid Ismail
Published: February 2022

Cet article étudie deux lettres envoyées par le chef de la famille des Kunta de l’Azaouad, al-Muḫtār al-Ṣaġīr al-Kuntī (m. 1847), à Aḥmad Lobbo (m. 1845) au moment de l’expansion de l’imamat de Ḥamdallāhi vers la Boucle du Niger dans les années 1830. Il s’agit de sonder comment la science du droit en Islam (fiqh) devient un moyen de communication politique puissant qui intervient directement dans les relations de pouvoir. J’analyse, d’un côté, la mobilisation des mécanismes contractuels du fiqh dans la gestion des rapports conflictuels entre groupes lignagers. De l’autre, je me penche sur le phénomène d’une « judiciarisation » du fait étatique perceptible dans les deux lettres. Al-Muḫtār al-Ṣaġīr appréhende la mainmise de Ḥamdallāhi sur la région de Tombouctou essentiellement à travers une grille de lecture forgée par les juristes musulmans après le xe siècle pour penser les fondements institutionnels de l’ordre public, à commencer par la judicature (al-qaḍāʾ). En explorant cette dimension performative du discours lettré musulman, j’espère proposer de nouvelles pistes de réflexion sur les dynamiques d’appropriation de modèles culturels issus de l’héritage littéraire arabo-islamique qui travaillent en profondeur les sociétés de l’espace sahélo-saharien à partir du xve siècle.
Whalebone and the Wardrobe of Elizabeth I
Authors: Bendall Sarah A.
Published: February 2022

During the sixteenth century the bodies of Europe’s elites began to change in size and form as both men and women adopted wide starched ruffs and collars, ballooning sleeves, stiffened or bombast upper garments and puffy lower garments. This early modern aristocratic body was the result of many different ideas that emerged during the sixteenth century, such as self-control, civility and physical uprightness. Often overlooked in explanations of late sixteenth-century fashions is the availability of new raw materials that allowed artisans to fabricate clothing that portrayed these aristocratic ideals. This article traces the emergence of baleen, an animal material derived from whales, in the wardrobe of Elizabeth I of England, to argue that the emergence of the queen’s recognisable early modern aristocratic European silhouette was closely tied to this industry and the trading networks it created. The use of whalebone to create the ostentatious fashions of the late sixteenth century demonstrate that fashion and whaling have been inextricably linked since at least the sixteenth century.
Le motif léopard dans le vestiaire féminin au XXe siècle
Authors: Buffard-Moret Julie
Published: February 2022

Plus courant que d’autres imprimés animaliers, le motif léopard est omniprésent dans les modes vestimentaires actuelles et apparaît partout dans notre univers visuel quotidien. De la veste en léopard « de Somalie » de Jacqueline Kennedy, en passant par les bikinis tachetés des pin-ups américaines des années cinquante, jusqu’à la robe clinquante du travesti Divine dans le film Female Trouble de John Waters (1974), cet article propose de suivre la circulation des taches de léopard dans le vestiaire féminin occidental au XXe siècle. D’abord sous la forme de fourrure authentique, importée d’Afrique, qui est utilisée pour confectionner une tenue iconique qui connaîtra un succès retentissant : le manteau en peau de léopard. Puis, sous la forme d’un imprimé industriellement reproduit qui prolifère et apparaît, après la Seconde Guerre mondiale, dans une garde-robe plus populaire. Cette enquête nous permettra d’interroger la représentation problématique des femmes en fauves prédateurs, en panthères.
Snakes’ commodification within the fashion system
Authors: Hugosson Annika
Published: February 2022

In the early 2000s a snake would appear as a prop in a live music performance, catalyzing a “trend” of live snakes as accessories which persists today on runways, red carpets, and on pages of fashion magazines. Around the same time, luxury fashion brands were selling out of snakeskin clothing and accessories, a trend which maintains popularity today. This paper applies a critical animal studies lens and insights from snake behavior literature to consider how live snakes are used in fashion performances and how they may be stressed by these environments. This article also discusses snakeskin as a distinct form of accessory which glamorizes and appraises snake death. Whether they appear alive or dead, the snake’s nonconsensual appearance on a runway, red carpet, or stage as a superfluous accessory trivializes and passivizes the snake. Surprisingly, such arguments find opposition from influential global conservation organizations, and the role of the luxury fashion industry is a controversial talking point in snake conservation.
Kahu kurī o awe: Fur cloaks of awe
Authors: Treadwell Justine
Published: February 2022

Kurī (Polynesian dogs in New Zealand) played a significant role in Māori life, including their skins as prestige garments, up until their disappearance in the mid 19th century. It is believed that kurī disappeared through interbreeding with imported species of dog and extermination by settler farmers. Brought on the original waka (canoes) from the Pacific Islands when the ancestors of Māori made landfall in New Zealand in c.1200AD, kurī were treasured pets, companions and sources for materials, and often had their whakapapa (genealogy) recited back to Polynesia parallel with their owners. Whakapapa is one of the contributing factors of a being’s mana (prestige) and tapu (sacredness). These concepts were firmly ascribed to kurī and set the frameworks for the relationships they formed with humans. The importance of this whakapapa in generating these qualities is investigated here in relation to the role kāhu kurī (dog skin cloaks) played in Māori society. The lens of animism allows us to consider the fluidity of mana and tapu between these animals and the garments they became. Kāhu kurī, now rare as their fabrication had ceased by the mid 19th century, are regarded broadly as garments of great prestige and association with rangatira (chiefs). How did this specific association occur? How, in turn, did it inform the relationship between kurī and humans? And most importantly, to what extent did it influence the adaptation of Māori weavers when kurī became scarce?

Welke morfologieën voor “inclusie in de stedelijkheid”? Onderzoek langs de Steenweg
Authors: Fenton Gabrielle , Visscher Jean-Philippe De , Hubert Michel
Published: February 2022

Le Steenweg, un axe est-ouest traversant le centre métropolitain de Bruxelles, est appelé à jouer un rôle clé dans la mise en œuvre de la vision de la mobilité future de la ville. En outre, une récente recherche [De Visscher et al., 2020] tend à indiquer que cet axe présente pour Bruxelles des enjeux importants en matière d’inclusion sociale. En prévision de futurs réaménagements, le présent article examine plus avant cette dernière hypothèse, en ouvrant des pistes de réflexion sur les possibilités d’« inclusion dans l’urbanité » le long du Steenweg. À partir de la proposition de Remy en faveur de la communication dans la distance [Remy, 2020 [1990]] et selon une approche socio-spatiale, l’article se concentre sur les morphologies qui contribuent à rendre possible un accès inclusif au tissu social et spatial de l’urbanité pour des groupes divers. À cette fin sont exposés les résultats d’une recherche exploratoire sur un type de morphologie présent le long du Steenweg : les galeries commerciales. L’article propose ensuite des pistes pour approfondir la réflexion sur les morphologies qui favorisent la communication dans la distance le long de cet axe en recensant tous les espaces accessibles au public au-delà des limites habituelles de l’espace public à ciel ouvert du Steenweg.

L’émirat de Dubaï demeure l’une des premières principautés du Golfe à avoir investi la sphère du sport spectacle au cours de la décennie 1990. Témoin des changements de génération au sein du pouvoir dubaïote, l’intégration à ce domaine marque aussi l’entrée de l’émirat dans une nouvelle ère par une image nouvelle de « cité globale ». Étudier Dubaï à travers le prisme du sport permet de comprendre, d’une part, comment l’émirat investit le terrain sportif et quels sont ses objectifs affichés, d’autre part, comment le sport se vit et se pratique au sein de la société aux origines multiples évoluant dans l’émirat. Le sport permet ainsi de mettre au jour, non pas un, mais plusieurs visages de Dubaï qui se superposent les uns aux autres sans jamais réellement se côtoyer sur le terrain sportif.

Published: February 2022

This paper discusses the U-shaped assembly line balancing problem in case of stochastic processing time. The problem is formulated using chance-constrained programming and the greedy randomized adaptive search procedure is used to solve the problem. In order to prove the efficiency of the proposed algorithm, 71 problems taken from well-known benchmarks are solved and compared with the theoretical lower bound and 13 of them were compared with another approach used to solve the same problem in another paper, which is beam search. The results show that 59 problems are the same as the theoretical aspiration lower bound. In addition, the results of 11 of 13 problems compared with beam search are the same and the results of 2 problems are better than beam search. The t-test statistics is applied and showed that there is no significance difference between the proposed algorithm and the theoretical lower bound thus, the proposed algorithm shows efficiency when compared with the aspired values of the theoretical lower bound.

The standard Whale Optimization Algorithm (WOA) involves exploitation and exploration operations which require to be balanced for improved performance. This paper suggests a new enhanced WOA to improve the convergence speed and enhance the global optimum by balancing exploitation and exploration processes. New stages have been suggested at the hunting stages of the WOA to increase the exploitation capability. The performance of the modified algorithm has been analyzed on few commonly used test functions and Reactive Power Optimization (RPO) problem. The numerical studies have shown that the proposed WOA variant has outperformed other compared optimization algorithms in terms of global optimum and convergence speed.

Published: February 2022

Transfer Learning (TL) can significantly lower training time and reduce dependency on a large number of target domain datasets. Such an approach is still not exploited for robotic prediction tasks. Currently, a TL based Artificial Neural Network (ANN) is explored and validated for robotic forward kinematics estimation of a 6-DOF robot. The robotic positions are estimated from the available joint angle information. The 6-R MTAB Aristo-XT robot is selected as a case study to generate the target experimental training and testing data for validation of ML techniques. While, the PUMA 560 6-DOF robot is used as a source for prior training of the ANN model. Standard performance measures such as learning error, deviation error and Mean Square Error (MSE) are evaluated and graphical illustrations are presented for fair comparison of the results. Experimental results reveal that, instead of ANN, the TL-ANN is strongly suggested to improve the training time of ANN regressor, and it also reduces the randomness and improves the accuracy as compared to its counterpart.

Published: February 2022

The current news information from different media websites has posed a serious problem, i.e., it is very difficult to obtain the satisfactory news contents from the measured data information. There have been some researches on news recommendation to improve the experience of users. In spite of this, they always need the further improvement because the news information has showed the explosive increasing way. Therefore, this paper studies knowledge graph and graph neural network (GNN) based news recommendation algorithm with edge computing consideration. At first, the knowledge graph is used for the knowledge extraction. Then, GNN is used to train the extracted features to complete the news recommendation algorithm. Finally, the edge computing is used to offload the high volumes of traffic to the edge server for the news recommendation computation. Compared with two baselines, the proposed algorithm is more efficient, increasing accuracy rate by 2.73% and 9.94% respectively, and decreasing response time by 84.27% and 87.58 respectively.

Authors: Singh Shweta , Kumar Rahul
Published: February 2022

RF spectrum decision is very crucial in cognitive radio. With the concept of interconnecting society by IoT, the spectrum demand has further raised exponentially and now it becomes very important to meet the problem of spectrum scarcity. Radio spectrum is a scarce commodity and due to shortage of radio spectrum, IoT networking has become very challenging in its implementation. Cyclostationary detection scheme, to able to sense RF spectrum and accordingly make decision to achieve good QoS and interference free communication is drawing the interest of researchers these days. In this paper, we propose to embed pilot subcarrier in OFDM signal to build the cyclic pattern in the signal of interest. This periodicity pattern is harnessed at the receiver end. Evaluation of this periodicity pattern forms the base regarding RF spectrum availability. The main aim of this paper is to show how cyclostationary detector performance can be improved. Pilot subcarriers are mainly used in this paper as a channel estimation parameter using different techniques to increase the detectability of detector.

T follicular regulatory (Tfr) cells are a subset of CD4+ T cells that express CXCR5 and migrate into germinal centers (GCs). They regulate GC reactions by communicating with T follicular helper (Tfh) and B cells. TNF inhibitors are used in inflammatory diseases; however, the generation of autoantibodies or anti-drug Abs sometimes causes problems. Because TNFR2 signaling is important for suppressive functions of regulatory T cells, we investigated the role of TNFR2 on human Tfr cells. Tfr cells stimulated with MR2-1 (an anti-TNFR2 agonistic Ab) were analyzed for cell proliferation, Foxp3 expression, and surface molecules. Tfh/B cell proliferation, IgM production, and differentiation in cocultures with MR2-1–stimulated Tfr cells were examined. Tfr cells express a high level of TNFR2. MR2-1 stimulation altered the gene expression profile of Tfr cells. Cell proliferation and Foxp3 expression of Tfr cells were enhanced by MR2-1. MR2-1–stimulated Tfr cells expressed ICOS and Programmed cell death protein 1 and significantly suppressed Tfh/B cell proliferation, IgM production, and B cell differentiation. TNFR2-stimulated Tfr cells retained the migration function according to the CXCL13 gradient. In conclusion, we showed that TNFR2-stiumulated Tfr cells can regulate Tfh and B cells. Aberrant antibody production during TNF inhibitor treatment might be, at least in part, associated with TNFR2 signaling inhibition in Tfr cells. In addition, expansion and maturation of Tfr cells via TNFR2 stimulation in vitro may be useful for a cell-based therapy in inflammatory and autoimmune diseases to control GC reactions.
Circulating T Cells Are Not Sufficient for Protective Immunity against Virulent Francisella tularensis

Pulmonary infections elicit a combination of tissue-resident and circulating T cell responses. Understanding the contribution of these anatomically distinct cellular pools in protective immune responses is critical for vaccine development. Francisella tularensis is a highly virulent bacterium capable of causing lethal systemic disease following pulmonary infection for which there is no currently licensed vaccine. Although T cells are required for survival of F. tularensis infection, the relative contribution of tissue-resident and circulating T cells is not completely understood, hampering design of effective, long-lasting vaccines directed against this bacterium. We have previously shown that resident T cells were not sufficient to protect against F. tularensis, suggesting circulating cells may serve a critical role in host defense. To elucidate the role of circulating T cells, we used a model of vaccination and challenge of parabiotic mice. Intranasally infected naive mice conjoined to immune animals had increased numbers of circulating memory T cells and similar splenic bacterial burdens as vaccinated–vaccinated pairs. However, bacterial loads in the lungs of naive parabionts were significantly greater than those observed in vaccinated–vaccinated pairs, but despite early control of F. tularensis replication, all naive–vaccinated pairs succumbed to infection. Together, these data define the specific roles of circulating and resident T cells in defense against infection that is initiated in the pulmonary compartment but ultimately causes disseminated disease. These data also provide evidence for employing vaccination strategies that elicit both pools of T cells for immunity against F. tularensis and may be a common theme for other disseminating bacterial infections.

Myocardial infarction with nonobstructive coronary arteries (MINOCA) in the context of acute ST elevation myocardial infarction (STEMI) is a challenging situation with no clear guidelines. In the absence of a consensus, optical coherence tomography (OCT) provides a better well-informed decision whether to stent or not. Herein, we report a case of MINOCA that underwent stenting of the proximal left anterior descending artery in the setting of extensive anterior wall STEMI in view of high-risk clinical presentation and OCT features of a ruptured plaque.

Background:

The vast majority of literature on atrial fibrillation (AF) is based on studies from the developed world that mainly includes Caucasian patients. Data on AF in other ethnicities is very limited. The aim of this hospital-based study is to evaluate the effect of concomitant hypertension (HTN) on the characteristics and outcomes of Middle Eastern Arab and South Asian patients with AF in the state of Qatar.

Materials and Methods and Results:

During the 20-year period, 3850 AF patients were hospitalized; 1483 (38.5%) had HTN, and 2367 (61.5%) without HTN. Patients with HTN were 11 years older, compared to non-HTN patients, and had a significantly higher prevalence of diabetes mellitus, chronic kidney disease, and dyslipidemia, compared to non-HTN patients. Furthermore, underlying coronary artery disease and heart failure were significantly more common but not valvular and rheumatic heart diseases which were more common in those without HTN. The rates of in-hospital mortality and stroke were significantly higher in the presence of HTN (5.3% versus 3.5%, and 0.7% versus 0.2% respectively, P = 0.001), compared to non-HTN patients.

Conclusions:

HTN is significantly associated with more comorbidities and worse clinical outcomes when it coexists with AF in hospitalized Middle Eastern Arab and South Asian patients.
