The primary aim of this original work is to provide a more in-depth insight into the relations between control parameters adjustments, learning techniques, inner swarm dynamics and possible hybridization strategies for popular swarm metaheuristic Firefly Algorithm. In this paper, a proven method, orthogonal learning, is fused with FA, specifically with its hybrid modification Firefly Particle Swarm Optimization. The parameters of the proposed Orthogonal Learning Firefly Algorithm are also initially thoroughly explored and tuned. The performance of the developed algorithm is examined (...) and compared with canonical FA and above-mentioned FFPSO. Comparisons have been conducted on well-known CEC 2017 benchmark functions, and the results have been evaluated for statistical significance using the Friedman rank test. (shrink)

This extended study presents a hybridization of particle swarm optimization with complex network construction and analysis. A partial population restart is performed in certain moments of the run of the algorithm based on the information obtained from a complex network analysis. The complex network structure represents the communication in the population. We present experimental results of the method alongside with statistical evaluation and discuss future possibilities of this approach. The main goal of the work is not to propose a new (...) highly competitive PSO variant but to present the possibility of using the unconventional tool as an alternative to conventional diversity measures. The main benefit of the network analysis is that it has same-time requirements regardless of the dimension of the problem. (shrink)

Though it is inter-disciplinary in scope, situated as it is on the borderlines of ontology and logic, philosophy of literature and theory of language, Ingarden's work has a deliberately narrow focus: the literary work, its structure and ...

A primary issue in the field of business and society over the past 25 years has been the relationship between corporate social performance and corporate financial performance. Recently, Griffin and Mahon (1997) presented a table categorizing studies that have investigated this relationship. Motivated by concerns with this table, as well as a desire to account for progress in research in this area, the authors reconstructed it. The authors present a portrait of this relationship that is (a) substantially different from that (...) shown in the Griffin and Mahon table and (b) more consistent with the latest research on the topic.

INTRODUCTION I have often asked myself why Husserl, really, headed in the direction of transcendental idealism from the time of his ...

The paper is devoted to the discussion of some philosophical and historical problems connected with the theorem on the undefinability of the notion of truth. In particular the problem of the priority of proving this theorem will be considered. It is claimed that Tarski obtained this theorem independently though he made clear his indebtedness to Gödel’s methods. On the other hand, Gödel was aware of the formal undefinability of truth in 1931, but he did not publish this result. Reasons for (...) that are also considered. (shrink)

Introduction The starting point for our reflections upon the musical work will be the unsystematized convictions that we encounter in daily life in our communion with musical works before we succumb to one particular theory or another.

The purpose here is to give a thorough phenomenological account of the aesthetic experience. The difference between cognitive perception of a real object and the aesthetic experience of an esthetic object is discussed at length. Elements and phases of an esthetic experience are delineated; illustrations of a preliminary emotion of esthetic experience are given, All of which suggest a fundamental change of attitude. From normal perceiving to esthetic perceiving there is a change from categorical structures to qualitative harmony structures, Producing (...) pleasure in the presence of an esthetic object. (staff).

”Rotu” mielletään usein pelkästään biologiseksi käsitteeksi. Niinpä rasismista syytetyt toisinaan puolustautuvat julkisuudessa sanomalla, että he eivät ole biologisten rotuoppien kannattajia, vaan esimerkiksi vain kannattavat kulttuurien oikeutta olla erilaisia. Historiallisissa yhteyksissä menneiden aikojen ajattelijoita saatetaan puolustaa sillä, että he eivät olleet ainakaan biologisia rasisteja. Erottelun taustalla on olettamus, että biologiaa koskevat ja kulttuuria koskevat käsitykset voidaan ongelmattomasti erottaa toisistaan. Tämän esityksen yhtenä pyrkimyksenä on pohtia biologia vs. kulttuuri -erottelun merkitystä rotua koskevissa käsityksissä, ja problematisoida sitä. Tarkastelun aineistona käytetään 1800-luvun lopun ja (...) 1900-luvun alun vaikutusvaltaisimpia ”klassisia” rotuteorioita. Näitä näkemyksiä luonnehditaan yleensä ”biologisiksi”. Vaikka rotuteorioiden juuria on etsitty antiikista saakka, ja vaikka eri vuosisatojen ajattelijoilta on helppo poimia rotuennakkoluuloja heijastavia kommentteja, tarkasteltuna ajanjaksona laskettiin se teoreettinen perusta, joille esimerkiksi 1930- ja 1940-lukujen rasistiset käytännöt rakennettiin. Harva enää vaivautuu lukemaan tuon aikakauden rotuteoreetikkoja tai edes tunnistaa heidän nimensä: rotuteoriat ovat tyypillistä pseudotiedettä, vailla itsenäistä älyllistä arvoa. Kuitenkin johtavien rotuteoreetikkojen kirjoitukset käännettiin aikanaan useimmille eurooppalaisille kielille, ja niitä myytiin satoja tuhansia kappaleita. Rotuajattelusta tuli liberalismin, sosialismin ja kommunismin kaltainen vaikuttava yhteiskunnallinen virtaus. Sen historiallisesti tunnetuin ilmaus oli Saksan kansallissosialismi, mutta lähes kaikissa Euroopan maissa – ja monissa Euroopan ulkopuolisissa maissa – syntyi paikallisesti värittyneitä versioita rotuopeista. Useimmissa maissa nämä opit syntyivät jo ennen kuin kansallissosialismista tuli Saksan hallitseva ideologia. Yhtäältä rotuopit sekoittuivat vanhempiin, kielellisesti ja kulttuurisesti muotoiltuihin nationalismin versioihin. Toisaalta ne kytkeytyivät usein biologisin käsittein muotoiltuihin ideoihin rodun parantelusta. Silti rotuopit erottuvat käsitteellisesti ja teoreettisesti sekä ”pelkästä” nationalismista että ”pelkästä” rotuhygieniasta. Tämän esityksen muina tavoitteina on pyrkiä muodostamaan historiallisesti ja filosofisesti täsmällisempi käsitys rasismia tukevasta ajattelusta. Samalla rotuopit toimivat kiinnostavana ja varoittavana esimerkkinä politiikan käyttöön valjastetun pseudotieteen argumentaatiotavoista. (shrink)

Der thematisch scharf umgrenzte Sammelband ist von grundlegender Bedeutung füuuml;r die Ästhetik der Gegenwart und vervollstäauml;ndigt Ingardens großen Entwurf einer philosophisch begründeten Theorie des Kunstwerks. Im Mittelpunkt der Eröouml;rterungen stehen das ästhetische Erlebnis, das Form-Inhalt-Problem im literarischen Kunstwerk und vor allem der Fragenkomplex des ästhetischen Wertes.

Enesidemo ha sido considerado, tradicionalmente, como figura mediadora entre el escepticismo pirroniano y el escepticismo académico. En el Códice 212 de su Bibliotheca, Focio proporciona alguna infonnación fundamental para reconocer a Enesidemo como figura clave del escepticismo entre Timón de Filunte y Sexto Empírico. Así, es corriente hablar de la pertenencia de Enesidemo a la academia platónica, y de su separación, cuando Filón de Larisa y su sucesor Clitx5maco empiezan a renunciar a los principios académicos y adoptan principios estoicos2, A (...) partir de aquí es corriente concluir que trabajaba por restaurar cierta originalidad de la especulación filosófica, basada en Pirrón, frente a todo el trabajo de reflexión y de análisis que él mismo había realizado en la academia en contra de los dogmáticos estoicos. La hipótesis de este artículo rompe esta ortodoxa interpretachin. Enesidemo es el primero en recuperar sistemáticamente los presupuestos del pensamiento pirroniano, generando un movimiento desconocido como tal hasta ese momento, el pirronismo shrink)

Parece que Platón enseñó en la Academia otras doctrinas diferentes de las expuestas por él en los diálogos. Además, parece también que voluntariamente se abstuvo de consignarlas por escrito al creer que la palabra, la enseñanza oral, era un medio más eficaz que la escritura para transmitir aquello que "tenía importancia". Dicho así, puede resultar una paradoja que el mejor prosista griego, sea un detractor, al menos en parte, de la prosa escrita. A partir de aquí, las interpretaciones novedosas que (...) han provocado las doctrinas no-escritas de Platón han generado debates a veces imposibles de resolver. Añadir unas breves notas a estas discusiones es la intención de este artículo. (shrink)

People have always tried to make predictions; they are necessary and useful, but very often they commit obvious errors, which have negative consequences on decision-making. Prediction errors are in some cases, not few, unavoidable, because the world itself is unpredictable, subject to chance (or randomness in mathematics). Chance is a property of nature. The causes of random events are physically determined, but so numerous and complex that they (the events) are unpredictable. Science is not about certainty. Human knowledge itself is (...) not certain. We can only have provisional truths. Therefore, we must manage to reach a state of accommodation with uncertainty and unpredictability. The complexity of natural phenomena generates events that we cannot control through theoretical modeling precisely because of the ignorance of the causal mechanisms, which exist in their privacy but have not (yet) been revealed by the data and observations at our disposal. We have, on the one hand, life experience taken over and assimilated and established in society and, on the other hand, experience gained from real life. Norm and chance follow each other rather chaotically. The duration of validity of a norm and the moment of occurrence of the random event are unpredictable. However, norms and events coexist in our consciousness. Order and predictability are born (formed and exist) from rules; chance and unpredictability are born from the lack of rules. The highest truths, recognized as such by society cannot be transposed into the life of society only by the force of reason. It is imperative that they are reinforced and embedded in the social behavior of all citizens. Rules are needed. Without rules there is no freedom. (shrink)
