Diosmetin Ameliorates Cerebral Ischemia/Reperfusion Injury in PC12 Cells Through Nuclear Factor-kB (NF-kB) and Nuclear Factor Erythroid 2-Related Factor/Heme Oxygenase-1 (Nrf 2/HO-1) Pathway
Authors: Lan Luan , Lanxiu Cao , Lei Zhu , Jianhua Sun
Published: January 2020

Diosmetin, a natural flavonoid, exhibits a variety of pharmacologic activities including inhibition of inflammation and oxidation. Therefore, its potential role in the management of cerebral ischemia/reperfusion (I/R) injury remains to be examined. In this study, we explored the underlying molecular mechanisms of diosmetin effects on cerebral ischemia/reperfusion injury in vitro. The results show that hypoxia/reoxygenation treatment of PC12 cells decreased cell viability and increased apoptosis, inflammation and oxidative stress. Diosmetin improved cellular viability, decreased lactate dehydrogenase release, and inhibited apoptosis in hypoxia-/reoxygenation-treated PC12 cells. Furthermore, diosmetin effectively inhibited the NF-kB signaling pathway to attenuate the inflammatory response. Also, diosmetin inhibited reactive oxygen species generation to attenuate I/R injury-induced oxidative stress in PC12 cells probably through the activation of Nrf 2/HO-1 pathway. Therefore, diosmetin effectively protected cells from I/R injury in nerve cells by scavenging reactive oxygen species by activating Nrf 2/HO-1 pathway and inhibiting inflammation by the suppression of NF-kB signaling pathway. Diosmetin can be regarded as a potential agent for cerebral ischemia/reperfusion injury treatment.
Antibacterial Activity of Water Soluble βb-Cyclodextrin Modified Graphene Oxide Materials
Authors: Lei Sang , Lin Tang , Wen-Tao Hao , Peng Cui
Published: January 2020

Graphene oxide (GO) continues to be interesting material due to their large specific surface area properties. In order to inhibit the aggregation and improve the water solubility of GO, “soft-cutting” technology was used for preparation of β-cyclodextrin modified graphene oxide materials (β-CD@GO). The formation of corrugations of β-CD@GO was evaluated by transmission electron microscope (TEM) observation. The β-CD@GO sheet exhibited appreciable water dispersion capacity than the pristine GO. According to further evidence from Raman spectroscopy, UV - vis, Fourier transform infrared spectra (FT-IR), X-ray diffraction (XRD), it can be deduced that some oxygen groups of GO were reduced by β-CD which were chemically absorbed on the GO surface, promoting the peeling of graphene layer. The β-CD@GO also exhibited thermal stability enhancement. Furthermore, the β-CD modified GO showed excellent inhibition on the bacterial growth due to the good dispersity of β-CD@GO. This approach is expected to provide a promising food preservation material in packaged food to counteract bacterial spoilage.

Published: January 2020

The purpose of this study was to evaluate the anti-fatigue activity of maca hydroalcoholic extract (ME), which mainly contains
macamides and polysaccharides. ME was prepared by circumfluence extraction with enzymatic pre-treatment. Anti-fatigue activity of ME was investigated in weight-loaded forced swimming mice, with pure macamides and commercially available maca tablet as positive control. Compared with normal group, pure macamides treatment group could prolong the swimming time to exhaustion, but there was no statistically significant difference (P > 0.05); while ME (middle-dose and high-dose groups) could effectively prolong the swimming durations (P < 0.05). Supplementation with pure macamides significantly decreased blood lactic acid (BLA), whereas ME significantly increased hepatic glycogen (HG), decreased BLA, and blood urea nitrogen (BUN) compared with those in normal control (P < 0.05). The results suggested that the anti-fatigue effect of ME was better than that of pure macamides, which can be explained by the increase of glycogen storage and the reduction of metabolites accumulation.

“Política e negociações” nos trilhos da convivência com o Semiárido
Authors: Sampaio Sieber Shana , Alves Gomes Ramonildes
Published: January 2020

O presente artigo busca refletir sobre o processo de implementação do Plano Municipal de Convivência com o Semiárido, no município de Serra Talhada - PE, problematizando a disputa de significados atribuídos ao discurso da Convivência com o Semiárido pela Sociedade Civil, através das Organizações Não Governamentais (ONGs), e pelo Estado, por meio do poder público. A análise desse processo nos leva a questionar o protagonismo da sociedade civil ante o contexto de proximidade desta com o Estado, produzindo uma espécie de Confluência Perversa. O exercício metodológico privilegiou a observação de reuniões, a análise de documentos e a realização de entrevistas. As evidências dão conta de que a Convivência, enquanto prática política, foi reduzida ao acesso a programas e políticas governamentais, à competição para a obtenção de cargos públicos e ao oportunismo político partidário, colocando em questão o potencial transformador da sociedade civil.

O artigo analisa o modo como diferentes compreensões da sociedade e economia brasileiras influenciaram as políticas públicas para a agricultura familiar ao longo dos últimos 20 anos. Dialogando com a abordagem cognitiva de análise de políticas públicas, o artigo analisa essa trajetória a partir das noções de referencial global, referencial setorial e mediadores de política pública. O estudo aponta que, ao longo dos 20 anos, dois referenciais globais (neoliberalismo e neodesenvolvimentismo) influenciaram as interpretações sobre o setor, alterando as relações de poder entre os atores envolvidos com as questões da agricultura familiar, da agricultura e do rural brasileiro, dando “palavra” a novas e diferentes ideias e interpretações. No período recente “novos mediadores” (atores que vinham tentando influenciar as políticas para a agricultura familiar no referencial global neodesenvolvimentista) angariaram espaço político, reativaram e recontextualizaram o referencial global neoliberal, e ajustaram as políticas para a categoria social de acordo com este.
La finance de marché à l’ère de l’intelligence bon marché
Authors: Lehalle Charles-Albert
Published: January 2020

Si l’intelligence artificielle (IA) a connu récemment de nombreux succès, il ne s’agit pas d’une discipline nouvelle, mais les outils fournis par les sciences des données l’ont amenée à un nouveau stade, qui lui permet de « résoudre des tâches complexes, sans être intelligente ». L’industrie de la finance de marché va être touchée par les innovations secondaires de l’IA dans trois directions : vers les clients et la fabrication de produits sur mesure, vers l’économie réelle et le nowcasting , et vers la gestion du risque. Ces innovations bousculent déjà l’organisation des acteurs de ce secteur, qui modularisent leurs services et s’organisent en plateformes. Dans un secteur à juste titre très régulé, certaines particularités des technologies de l’IA, à savoir l’importance des données et l’utilisation de librairies logicielles tierces, peuvent apparaître comme de nouvelles sources d’incertitude.

L’impact des Fintech sur la structure des marchés bancaires
Authors: Weill Laurent
Published: January 2020

L’article étudie comment les Fintech peuvent affecter la structure des marchés bancaires. Les Fintech possèdent plusieurs avantages concurrentiels sur les banques traditionnelles. Ils disposent de coûts plus réduits de par l’utilisation des technologies de l’information et de la communication au cœur de leur modèle d’affaires. Ils peuvent offrir des services de meilleure qualité comme une réactivité plus grande face à la demande d’un crédit. Il existe cependant des limites à l’impact des Fintech. Les banques traditionnelles peuvent bénéficier d’un avantage en termes de coûts financiers du fait de leur activité de collecte de dépôt. L’avantage technologique des Fintech est également plus ou moins important selon que l’information privée sur l’emprunteur joue un rôle important sur le marché du crédit.

Stratégies de la banque de détail face à la révolution technologique
Authors: Klein Olivier
Published: January 2020

La remise en question de la pérennité du modèle bancaire traditionnel prend une acuité nouvelle. Et ce dans un contexte conjoint de mutations technologiques majeures favorisant l’émergence de nouveaux modèles – comme celui des « néobanques » entièrement en ligne, des Fintech ou des GAFA qui arrivent dans le secteur bancaire – et de conditions macrofinancières très défavorables. Or il existe aujourd’hui une croyance forte que la seule possibilité de s’en sortir face aux nouveaux modèles serait un repli défensif, une réduction de la voilure des banques de détail sur leur territoire. En revenant aux fondamentaux de l’activité de banque de détail, cet article vise à démontrer qu’elles ont en fait des atouts structurels pouvant être mis en avant face aux nouveaux modèles émergents. Mais, pour cela, les banques doivent, dans une vision offensive de leur activité, apporter toujours plus de valeur ajoutée à leurs clients, dans un modèle renforcé de relation globale. Cela passe par des investissements significatifs dans la formation et le digital, et aussi, le cas échéant, parfois par des alliances avec les nouveaux acteurs du secteur bancaire.

La banque de l’ombre est-elle un complément ou un substitut aux institutions financières traditionnelles ? Une étude empirique sur données internationales
Authors: Madiès Philippe , Said Zeinab , Taramasco Ollivier
Published: January 2020

En utilisant un échantillon de vingt-six pays sur la période 1990-2013, nous examinons empiriquement le lien entre la taille du système bancaire de l’ombre et celle des institutions financières traditionnelles, à savoir les banques et les investisseurs institutionnels. Nous effectuons tout d’abord une étude sur l’ensemble de l’échantillon ainsi que sur les pays de la zone euro et nous procédons ensuite à un examen pays par pays. Il s’agit de savoir si la finance de l’ombre et la finance conventionnelle doivent être considérées comme des compléments ou des substituts. Nos résultats tendent à montrer que le système bancaire de l’ombre complète plutôt qu’il ne remplace les activités des institutions financières traditionnelles, notamment des banques. Le parrainage par les banques des activités bancaires parallèles a clairement renforcé ce lien. Classification JEL : G20, G21, G23, G24, G28.
Renouvellement urbain et optimisation du métabolisme : une équation complexe
Authors: Fernandez Mathieu , Blanquart Corinne , Niérat Patrick , Verdeil Éric
Published: January 2020

Dans le contexte des appels à encourager une transition socio-écologique atténuant les pressions et les prélèvements sur les ressources naturelles et environnementales, les flux de la construction apparaissent comme un levier d’intervention majeur. Jouer sur les formes urbaines, en encourageant la compacité et la densité, apparaît dès lors comme une politique vertueuse, susceptible de réduire la consommation de sols naturels ainsi que les prélèvements matériels. L’article éclaire au contraire une dynamique contradictoire entre les flux de matières qui tendent à devenir majoritaires dans l’extension de l’empreinte de la ville sur son environnement et la doctrine du renouvellement urbain qui vise à limiter l’extension urbaine. Dès lors, il nous semble essentiel de considérer l’impact de scénarios d’aménagement ou de gestion des flux de matériaux de construction eu égard au taux de valorisation, aux émissions en équivalence CO 2 , mais aussi à la consommation d’espace associé à la gestion de ces flux. Le dispositif méthodologique développé éclaire ainsi l’impact parfois antagoniste d’un même scénario : une attention particulière à la valorisation est ainsi associée à une augmentation des distances et donc des émissions, tandis qu’une ambition de report modal contribue à l’extension urbaine.
Conditions and concepts for interdisciplinary urban metabolism research–the case of an inter-project collaboration on biowaste
Authors: Bortolotti Andrea , Kampelmann Stephan , Muynck Simon De , Papangelou Anastasia , Zeller Vanessa
Published: January 2020

La nécessité d’approches interdisciplinaires dans l’analyse du métabolisme urbain a été soulignée maintes fois, et les difficultés que rencontre la recherche interdisciplinaire sur le métabolisme urbain ne résident pas dans le manque de volonté des chercheurs. Nous soutenons que le problème central réside dans les détails pratiques, organisationnels et parfois banaux du travail entre équipes de recherche, départements et temporalités. Dans cet article, nous proposons une description fine d’une collaboration interdisciplinaire qui s’est produite dans la pratique : un effort conjoint pour développer et évaluer des scénarios de transition concernant le métabolisme des biodéchets dans la ville-région de Bruxelles. Cette collaboration entre projets a impliqué quatre équipes de recherche différentes issues de trois facultés et de deux universités, chacune possédant un ensemble spécifique de compétences et d’intérêts. Le métabolisme des biodéchets et la recirculation des nutriments est un thème récurrent dans la littérature sur le métabolisme urbain. Notre travail fait donc écho à des études antérieures sur le métabolisme urbain et à des problèmes d’épuisement de la fertilité des sols et de différentes formes de pollution. Le papier décrit le point de départ de chaque projet de recherche afin de permettre aux lecteurs de disciplines différentes d’appréhender la distance qui les séparait avant qu’ils aient décidé de travailler ensemble sur le métabolisme des biodéchets urbains. De plus, nous présentons des moments de convergence qui ont permis de rapprocher ces processus de recherche. Enfin, nous proposons une réflexion critique, revenant à la fois sur les facteurs favorables et les limites de la collaboration entre projets sur le métabolisme des biodéchets à Bruxelles.
Le rôle des compétitions territoriales dans la transition énergétique
Authors: Tanguy Audrey
Published: January 2020

De par une réorganisation de la spatialité des modes de production et de distribution d’énergie, la transition énergétique modifie de manière significative les relations intra- et interterritoriales, qui obéissent à une double logique de coopération et de compétition. Elle amène donc à s’interroger sur ces rapports de force en mutation, et dont la caractérisation est essentielle dès lors que l’on cherche à mieux appréhender l’évolution du métabolisme d’un territoire. En adoptant une approche multidisciplinaire de l’étude du métabolisme sur le cas d’un territoire portuaire, cet article propose d’examiner les typologies de compétitions territoriales selon différentes échelles (locale, régionale et internationale) et d’identifier le rôle qu’elles peuvent jouer dans la mise en œuvre de projets de transition énergétique. L’analyse multiscalaire met à jour une diversité de compétitions qui ne se réfèrent pas toutes aux mêmes enjeux. Elle met aussi en évidence l’incidence de la perception spatiale des acteurs sur la nature d’une relation (compétition ou complémentarité) entre différents éléments (entre ressources, entre territoires). Enfin, cette recherche montre que si les compétitions peuvent parfois constituer un frein à la mise en œuvre d’une transition territoriale, elles peuvent aussi être à l’origine d’une complémentarité dans les projets énergétiques.
« Quelle agréable aventure vous conduit ici, Madame ? » : de la bise galante aux vents viatiques, Regnard l’aventurier
Authors: Requemora-Gros Sylvie
Published: January 2020

Jean-François Regnard est un cas intéressant de voyageur aventurier et de joueur aventureux, permettant de penser l’aventure du voyage en même temps que l’aventure de l’écriture du voyage d’un auteur dont l’éthique existentielle de la vie est vécue et écrite comme une aventure viatique. De son récit romancé de captivité en Algérie La Provençale à sa véridique aventure nordique poursuivie jusqu’en Laponie dans ses Voyages , Jean-François Regnard permet d’interroger la figure de l’aventurier.
La nouvelle historique : la brièveté se nourrit-elle d’aventures ?
Authors: Zonza Christian
Published: January 2020

De nombreux romans dans la première moitié du XVII e  siècle cherchent à divertir le lecteur en multipliant les aventures. Cela est possible grâce à leur longueur, au nombre de personnages, à la diversité des lieux où l’action se déroule. L’apparition de nouvelles historiques au milieu du siècle a signifié de ce fait la réduction du nombre de pages, de lieux, de personnages et une exigence de vraisemblance. Le principal défi pour ces auteurs de nouvelles consiste à conserver tout l’intérêt du lecteur avec des moyens limités. Comment s’y prennent-ils donc pour combiner plaisir des aventures d’une part, brièveté et vraisemblance d’autre part ?
L’épistolaire, lieu de l’aventure au féminin : l’« étoile errante » des sœurs Mancini
Authors: Freidel Nathalie
Published: January 2020

Les lettres de Sévigné, de Bussy et de leurs cercles d’écriture ont mis en feuilleton les aventures des sœurs Mancini et de leur complice, Mme de Courcelles. Le vagabondage des épouses rebelles est objet de scandale mais aussi source d’inspiration pour les épistoliers et leur public. On condamne l’extravagance des fugueuses mais on suit de près leurs procès et leurs errances, jusqu’à proposer une relecture de l’aventure féminine, dont la lettre sévignéenne exploite le potentiel émancipateur.
Ne rien attendre de la fortune ou la disqualification cartésienne de l’aventure
Authors: de Peretti François-Xavier
Published: January 2020

Fort rare, le terme d’ aventure n’apparaît chez Descartes que pour évoquer des fictions théâtrales ou romanesques. Et pour cause : l’hagiographie célébrant l’héroïsme de « ce cavalier français parti d’un si bon pas » dissimule mal une disqualification de toute forme d’aventure, la volonté farouche ne rien devoir à la fortune et une quête constante d’assurance, d’ordre, de mesure et de certitude soucieuse de ne laisser, dans sa pensée comme dans sa vie, aucune prise au hasard et aux circonstances.

Transitions énergétiques à Istanbul et Le Cap
Authors: Arik Elvan , Jaglin Sylvy , Verdeil Éric
Published: January 2020

Cet article propose d’élargir le débat sur la transition énergétique au-delà du contexte occidental. Partant d’études de cas situées dans deux métropoles des Suds, la réflexion invite à nuancer les scénarios normatifs et supposés universels de transformation des systèmes énergétiques pour confronter les transitions aux singularités des sociétés et des territoires dans lesquels elles prennent forme. Ainsi s’aperçoit-on que les discours sur le changement climatique global ont bien moins d’effets d’entraînement sur les trajectoires énergétiques d’Istanbul et du Cap que l’impact de crises écologiques plus locales ou que l’évolution de compromis socio-politiques, toujours fragiles et dépendants d’héritages historiques nationaux.

Cet article mobilise la notion d’« approche transactionnelle », empruntée à John Dewey et Arthur Bentley, pour nous inviter à concevoir les images circulant sur nos réseaux électroniques au-delà des représentations dont elles sont porteuses à la surface des écrans. Comprendre leur dynamique implique de prendre en compte les multiples couches dont elles se composent, depuis la matérialité des flux électriques, à travers les strates de langages-machine, les protocoles de transfert ou le design des interfaces. L’image que nous identifions et isolons dans ses traits figuraux apparaît comme un leurre cachant les implications multiples des transactions dont elle résulte – et qu’il faut apprendre à repérer pour en déjouer certaines illusions.
Eléments pour l’ébauche d’une socio-histoire du groupe professionnel infirmier. Un fil conducteur : la formation des infirmières et de leurs cheffes
Authors: Divay Sophie , Girard Lucile
Published: January 2020

Cet article retrace certaines des dynamiques du groupe professionnel infirmier depuis son émergence à la fin du XIX è me siècle en France. Notre propos suit le fil conducteur des évolutions des dispositifs de formation mis en place pour les infirmières, puis pour leurs cheffes. Les éléments rassemblés ici œuvrent pour la constitution d’une socio-histoire du monde infirmier et de la complexité de ses dynamiques. Elles se manifestent dans un premier temps à travers les luttes entre les promoteur-e-s de définitions divergentes, voire antagonistes, de l’« infirmière moderne », chacun-e proposant des modèles de fabrication (formation et socialisation de ces soignantes) plus ou moins contrastés. L’entrée en scène progressive du segment des cheffes d’infirmières contribue à l’avènement d’une des premières formes d’autonomisation et d’affirmation du groupe professionnel qui au fil du temps va stratégiquement adhérer, en les combinant, à différentes idéologies (des principes humanistes des soins infirmiers aux orientations managériales gestionnaires, en passant par une conception biomédicalisée du travail infirmier). Les analyses présentées ici s’appuient sur un travail de thèse soutenue en 2018 et sur de nombreuses enquêtes menées depuis des années tant dans les instituts de formation des infirmières que sur leurs lieux de travail à l’hôpital.
La rémunération des élus
Authors: Demazière Didier , Le Saout Rémy
Published: January 2020

Cet article explore l’accès à la professionnalisation politique, au sens wébérien de « vivre de la politique ». Il analyse en particulier les articulations entre revenus issus de mandat(s) et revenus d’emplois antérieurs, et l’abandon des seconds au profit des premiers. Il mobilise une enquête par entretiens auprès d’élus qui occupent des positions intermédiaires dans le champ politique, c’est-à-dire des élus pour qui la question de la professionnalisation se pose de manière aiguë. Deux dimensions de celle-ci sont traitées successivement : les règles formelles qui associent un niveau d’indemnité à chaque catégorie de mandat et définissent des possibilités inégales de vivre des positions électives ; puis les situations professionnelles et familiales des élus qui contribuent à alimenter des arbitrages et à construire des rapports différenciés à la rémunération du travail politique.
Competency Based Approach: Modeling and Implementation
Authors: Sedra Malika , Bennani Samir
Published: January 2020

The expansion of computer networks has at the same time given impetus to the distance learning environments. E-learning systems are also advanced and more efficient. However, these platforms offer such complex teaching functionalities that designers find themselves poorly equipped to succeed in their engineering processes. This article presents a tool that makes it easier for designers to produce educational content according to the Competency-Based Approach (CBA). We propose an implementation of the CBA after its modeling via ontology. Our module can be grafted to any author system oriented pedagogy based skills. We have advocated for Service for Oriented Architecture as a software solution to model our business process that consists of a set of interconnected services that are modeled and implemented. The proposed system is the result of a coordina-tion of, services, incorporating the order of competences explained by a distance education, which integrates and interacts according to an orchestration plan.

Published: January 2020

In this research, we aggregated students log data such as Class Test Score (CTS), Assignment Completed (ASC), Class Lab Work (CLW) and Class Attendance (CATT) from the Department of Mathematics, Computer Science Unit, Usmanu Danfodiyo University, Sokoto, Nigeria. Similarly, we employed data mining techniques such as ID3 & J48 Decision Tree Algorithms to analyze these data. We compared these algorithms on 239 classification instances. The experimental results show that the J48 algorithm has higher accuracy in the classification task compared to the ID3 algorithm. The important feature attributes such as Information Gain and Gain Ratio feature evaluators were also compared. Both the methods applied were able to rank search method and the experimental results confirmed that the two methods derived the same set of attributes with a slight deviation in the ranking. From the results analyzed, we discovered that 67.36 percent failed the course titled Introduction to Computer Programming, while 32.64 percent passed the course. Since the CATT has the highest gain value from our analysis; we concluded that it is largely responsible for the success or failure of the students.
Towards a New Platform Based on Learning Outcomes Analysis For Mobile Serious Games
Authors: Elaachak Lotfi
Published: January 2020

Nowadays, learning via smartphones has become one of the most popular teaching tools used by young people, thanks to the ease of use of such devices in the field of education. There are now a large number of both instructional applications and mobile serious games "MSGs" which are available in mobile applications stores. The diversity of such applications especially MSGs can guarantee a personalized learning experience for each learner. However, it is difficult to decide if a given MSG is efficient or not because this decision depends on several factors. One of those major factors is their ability to transmit knowledge effectively to the learners, in order to teach them new skills. This ability can be measured and then analyzed by using several techniques and algorithms like learning analytics, educational data mining, inference knowledge e.g. "Bayesian Knowledge Tracing", etc. Hence the need for the establishment of a user-friendly platform based on these algorithms, the proposed platform will be able to evaluate easily the learning outcomes of this kind of video games.
Visual Education of Music Course for College Students Based on Human-Computer Interaction
Authors: Li Yifeng
Published: January 2020

Visual education is an emerging education method in many Chinese colleges. However, the visual education in Chinese colleges has not attached enough importance to the hands-on ability and comprehension ability of college students. To solve the problems, this paper designs and applies a visual education method for music courses in colleges based on the human-computer interaction system. Special attention was paid to the formulation of the human-computer interaction system, which is essential for visualization of music information. Based on the master-slave mode, the human-computer interaction system introduces the cloud control into the visual education of music. The proposed method was verified through the application in a university of Nanjing, China. The results show that our method greatly boosts the acquisition of music information by college students and effectively arouses their interests in music. The research results lay the basis for wider application of visual technology in education.
Neighborhood-Based Classification of Imprecise Data
Authors: Sundaram Sampath , Simon Miriam Kalpana
Published: January 2020

This chapter considers k-nn classification of objects that assume values of imprecise nature with respect to attributes being considered. In order to handle imprecise data values, two approaches of crisp conversion of fuzzy data sets are considered. The approaches considered in this chapter are borrowed from Credibility Theory of Liu. A comparative study on the choice of approach for crisp conversion of fuzzy data has been carried out with the help of certain multivariate simulated data sets. Conclusions drawn from the study are presented.
Bipolar Fuzzy Structure of H-Ideals in BCI-Algebras
Authors: Senapati Tapan , Chen Guiyun
Published: January 2020

In this chapter, the concepts of bipolar fuzzy H-ideals of BCI-algebras are introduced and their natures are investigated. Relations between bipolar fuzzy subalgebras, bipolar fuzzy ideals, and bipolar fuzzy H-ideals are discussed. Conditions for a bipolar fuzzy ideal to be a bipolar fuzzy H-ideal are provided. Some characterization theorems of bipolar fuzzy H-ideals are established. A bipolar fuzzy H-ideal is established by using a finite collection of H-ideals. The authors have shown that if every bipolar fuzzy H-ideal has the finite image, then every descending chain of H-ideals terminates at finite step.

Authors: Bej Tripti , Jun Young Bae
Published: January 2020

This chapter focuses on the basics of a theory for such an interval-valued fuzzy set becoming doubt interval-valued fuzzy subalgebra and doubt interval-valued fuzzy ideal in BF-algebras. After a detailed study of its properties, the authors come to the conclusion that in BF-algebras an interval-valued fuzzy set in BF-algebras is a doubt interval-valued fuzzy subalgebra and a doubt interval-valued fuzzy ideal if and only if the complement of this interval-valued fuzzy set is an interval-valued fuzzy subalgebra and an interval-valued fuzzy ideal.
Fuzzy Similarity Relations in Decision Making
Authors: El Alaoui Mohamed , El Yassini Khalid
Published: January 2020

Similarity is an ambiguous term that can be interpreted differently depending on the context of use. In this chapter, the authors review some of its uses before focusing on decision making. Ignoring the uncertainty of human knowledge would be denying a major attribute. Thus, they linked it to the fuzzy context. However, even taking this aspect into consideration, the opinion itself must be relevant. Therefore, the more a decision is similar to other opinions, the more it is coherent. Hence, there is a need to measure the similarity between each couple of expressed opinions.
Application of Fuzzy Logic in Investment-Intensive Decision Making
Authors: Pandey Prateek , Kumar Shishir , Shrivastava Sandeep
Published: January 2020

Fuzzy logic has been serving the industry for decades by resolving the ambiguities that appear as a result of imprecise environment. High-stake decision-making processes require inputs from various stakeholders to incorporate. If the risk is high, as in the case of high investment decision making, a robust system of incorporating opinions from multiple stakeholders must be set in place in order to avoid any inconsistency or bad decisions. Fuzzy matrices and arithmetic can play a rescuer in such situations. In this chapter, the authors demonstrate a decision-making framework incorporating the use of fuzzy numbers and arithmetic to make critical decisions in strategic marketing and new product development. Forecasting in the domains of new products is an utmost complex and critical process because no relevant history is available owing to the product's ‘one-of-its-kind' nature. In such cases, computation via analogy is an interesting paradigm, which is also discussed in the chapter.

Published: January 2020

Global companies work on strategies to capture their position in the marketplace, operating on their market share to understand the demand supply equation of the spare parts. Buyers focus remains on the warranty period of the parts, till it exists they get it exchanged or purchase them. Once the warranty expires the purchase frequency transforms to spurious spare products as they get monetary advantage over others. Spurious markets have strong market share and position in fulfilling demands of the spare parts of the earth moving equipment. They produce imitated products which reassemble the original products, sell them to the vendors in spurious markets. To estimate the assessment on market share of spurious spare parts of ABC Earth Moving Equipments Pvt. Ltd, market research was carried out in the wholesale market selling and purchasing spurious earth moving spare parts. The outcome indicates that there is a notable influence on the profits of the company due to sale of the spurious spare products.
