Solvable groups derived from fuzzy hypergroups
Get PDFIn this paper we introduce the smallest equivalence relation ξ ∗ on a finite fuzzy hypergroup S such that the quotient group S/ξ ∗ , the set of all equivalence classes, is a solvable group. The characterization of solvable groups via strongly regular relation is investigated and several results on the topic are presented
A decision-making process for evaluating the effectiveness of strategies for social inclusion of persons with disabilities.
No full textIn this paper we analyze the problems of disabled people in Italy and possible strategies for their social inclusion. Subsequently we present a hierarchical analytical procedure to focus on the objectives and criteria to address these issues. Finally we presents a picture of sustainable alternatives and presents a general decision-making process for the analysis of the validity of the various alternatives. Among the possible choices for the allocation of weights and scores, we highlight the effectiveness of the Analytic Hierarchy Thomas L. Saaty Process (AHP) based on interviews and pairwise comparisons. Un processo decisionale per la valutazione dell’efficacia di strategie per l’inclusione sociale delle persone con disabilità.Si analizzano le problematiche delle persone con disabilità in Italia e le possibili strategie per la loro inclusione sociale. Successivamente si presenta una procedura analitica gerarchica per mettere a fuoco gli obiettivi e i criteri per affrontare tali problematiche. Infine si presenta un quadro di alternative sostenibili e si presenta un generale processo decisionale per l’analisi della validità delle varie alternative. Fra le possibili scelte per l’attribuzione di pesi e punteggi si evidenzia l’efficacia del Analytic Hierarchy Process (AHP) di Thomas L. Saaty basato su interviste e confronti a coppie.Parole Chiave: disabilità, inclusione sociale, Procedura AHP per le decision
Bourdieu sociologist of Flaubert
No full textBourdieu sociologue de FlaubertLes règles de l’art, écrites dix avant la mort de Pierre Bourdieu (2002), occupent une place importante dans la production du sociologue français, qui inscrit le rôle social de l’artiste, de l’écrivain en particulier, dans un “champ” conflictuel, qui peut être défini comme un ordre imposé par des forces sociales extérieures, politiques surtout, que la commercialisation impose sur le marché. Il s’agit surtout de comprendre pour le sociologue la genèse sociale du champ littéraire, tout en reconnaissant un jeu de complicité entre auteur et lecteur et tout en passant de l’autoanalyse à la socioanalyse.Au-delà de l’idée fondamentale dans la sociologie de Bourdieu centrée sur la lutte entre dominants et dominés, Bourdieu essaye de définir dans ce livre une vraie science rigoureuse de l’œuvre d’art, que nous allons résumer, tenant compte des conventions sociopolitiques qui sont à la base de la réception de l’œuvre littéraire, dans un contexte politique et historique précis, qui tient compte surtout de la période entre la révolution 1848 et le coup d’État de Napoléon (1852), tout en suivant les débats sur l’école réaliste et les procès que Flaubert et Baudelaire doivent subir comme deux défenseurs de l’autonomie de l’art.Mots-Clés: sociologie de l’art et de la littérature. Le champ littéraire; l’indétermination, le monde des relations sociales. L’Éducation sentimentale. Les protagonistes. Baudelaire et Flaubert contraires à la vision bourgeoise de l’art. L’invention de l’intellectue
Questionnaires with the ‘bar’ in social sciences
Get PDFVougiouklis & Vougiouklis have proposed the replacement of Likert scales, usually used in questionnaires, with a bar. With this proposal a discrete situation is replaced by a fuzzy one. There are identified certain advantages concerning the use of the bar as compared to that of a scale during both the stages of filling-in as well as processing a questionnaire. The main advantage is the fact that it is much quicker to fill in and much easier to explain to participants. The bar provides the potential for different types of processing Likert scales cannot offer. Therefore the researchers are allowed to ascertain that the given answers follow the Gauss or a parabola distribution, and they have the opportunity to ‘correct’ this tendency. In this research it is offered a possibility of choosing amongst a number of alternatives by utilizing fuzzy logic in the same way as it has already been done in industry and combining mathematical models with multivalued operations. Finally, the suggested method is applied in a Course and Teaching Evaluation process by the students of Democritus University of Thrace
Approach of the value of an annuity when non-central moments of the capitalization factor are known: an R application with interest rates following normal and beta distributions
Get PDFThis paper proposes an expression of the value of an annuity with payments of 1 unit each when the interest rate is random. In order to attain this objective, we proceed on the assumption that the non-central moments of the capitalization factor are known. Specifically, to calculate the value of these annuities, we propose two different expressions. First, we suppose that the random interest rate is normally distributed; then, we assume that it follows the beta distribution. A practical application of these two methodologies is also implemented using the R statistical software
Neutrosophic filters in BE-algebras
Get PDFInthispaper, weintroducethenotionof(implicative)neutrosophicfilters in BE-algebras. The relation between implicative neutrosophic filters and neutrosophic filters is investigated and we show that in self distributive BE-algebras these notions are equivalent
Need for global and cultural awareness
Get PDFCurrent and future operations and activities are more and more characterized by multinational collaboration, whether providing humanitarian assistance or keeping the peace, a single nation team is not able to work alone. Cultural adaptability and competence can significantly form the basis of a team performance
Fuzzy sets: motivations and first concepts
No full textStarting from the Russel’s studies on the limits of the empiricism, some considerations about the concept of vagueness, are recalled in order to stress the motivations and the development of a foundational context for the fuzzy sets. The description of the facts of the physical reality expressed in terms of fuzzy sets draws its origin from the objective of “calculating with words” being vagueness in the facts and in the language representing them. The unique operations that satisfy a system of reasonable requirements are defined. A measure of the degree of fuzziness, the fuzzy entropy, is defined in terms of a functional over the fuzzy sets. Insiemi fuzzy: motivazioni e primi concettiMovendo dall’indagine di Russell sui limiti dell’empirismo, sono riprese alcune considerazioni relative al concetto di vaghezza, allo scopo di porre in evidenza le motivazioni e lo sviluppo di un contesto fondazionale degli insiemi fuzzy. La descrizione dei fatti della realtà fisica effettuata in termini di insiemi fuzzy trae origine dall’obiettivo di “calcolare con le parole” in presenza della vaghezza presente nei fatti e nel linguaggio che li rappresenta.Parole Chiave: vaghezza, insiemi fuzzy, misure di fuzzines
Fundamental hoop-algebras
Get PDFIn this paper, we investigate some results on hoop algebras and hyper hoop-algebras. We construct a hoop and a hyper hoop on any countable set. Then using the notion of the fundamental relation we define the fundamental hoop and we show that any hoop is a fundamental hoop and then we construct a fundamental hoop on any non-empty countable set
Beneish M-score and detection of earnings management in Italian SMEs
Get PDFAccounting literature on the reliability of financial information presents several mathematical models whose purpose is to identify the existence of values manipulations. The phenomenon is described as earnings management and presents a broad discussion concerning the search for suitable models to measure the distortions in values. In this respect, the present paper aims to compare the ability of two versions of the same mathematical model of classify the risk of earnings manipulation in a discriminant way
