In this paper, the Helmholtz equation with quadratic damping themes is used for modeling the dynamics of a simple prey-predator system also called a simple Lotka–Volterra system. From the Helmholtz equation with quadratic damping themes obtained after modeling, the equilibrium points have been found, and their stability has been analyzed. Subsequently, the harmonic oscillations have been studied by the harmonic balance method, and the phenomena of resonance and hysteresis are observed. The primary and secondary resonances have been researched by the (...) multiple-scale method, and the conditions of stability of the amplitudes of oscillations are determined. Chaos is detected analytically by the Melnikov method and numerically using the basin of attraction, the bifurcation diagram, the Lyapunov exponent, the phase portrait, and the Poincaré section. The effects of all the parameters of the system are analyzed in detail, and special emphasis is placed on the new parameters. Through this analysis, the complex phenomena such as hysteresis, bistability, amplitude jump, resonances, and chaos have been obtained. The control of the parameters and the necessary conditions to control the aforementioned phenomena have been found. (shrink)

The publication presents the initial passages of the famious Pali Brahmajālasuttanta with the corresponding parts of its traditional commentary Sumaṅgalavilāsinī as a sample of the ancient hypertext. It is meant as a valuable source to such fundamental philological and hermeneutical questions as what is commented ans what is disregarded by the commentator; how, why and whatfore is in commented.

The philosophical disposition of the mind of Vladimir Bibikhin is deeply related to the thought of Martin Heidegger, but at the same time his existential character is almost directly opposite. What is common to them is the understanding of thought as the docile attention to the event of being. The text outlines three aspects of this disposition of mind, which all are disputed by the author. (1) Consciousness is not only the Carthesian ruler, but also the subject of the ethical (...) reflexion, conscience. (2) In the “seizedness” as the basic frame of mind of the docile attention the turn of the possessedness is concealed. (3) In the political turn of the seizing historical event the totalitarian power is hidden. (shrink)

The purpose of the present article is not an excursion into the history of philosophy. It is not a story of the adventures of Immanuel Kant on Russian soil, and even less does it pretend to expound systematically the perception of Kantian philosophy by Russian metaphysics. The author's interest is strictly philosophical. Russian religious thought, insofar as it has an appetite for philosophizing, consciously enters into the life of classical European philosophy, into that living communication of minds by which truth (...) is sustained, moved, and nourished among people and nations.2 A clarification of its personal relations with the central figures of this philosophical drama will help us to understand the strictly philosophical significance of Russian metaphysics more accurately than even sometimes the most dedicated description of it in itself succeeds in doing.

The author analyzes the basis of Mamardashvili's lectures on Proust in terms of tension between two polar concepts—the fully individuated work and the universal, metaphysical symbol.

Este volume oferece o primeiro conjunto de artigos exclusivamente dedicados à noção de «retomada», tal como a entendeu Eric Weil (1904-1977), escritos por investigadores oriundos de Portugal, França, Brasil, Itália, Roménia, Burkina Faso e Chile. Nascido na Alemanha, Eric Weil foi discípulo de Ernst Cassirer que o orien­tou no estudo dos filósofos do Renascimento, como Pietro Pomponazzi e Marsílio Ficino. Naturalizado francês, após ter sido obrigado a abandonar o país de origem, contra o qual...

Com este conjunto de treze artigos introdutórios, pretende-se apontar e, parcialmente, preencher uma lacuna significativa nos estudos sobre a Filosofia em Portugal e no Brasil. Com efeito, uma investigação bibliográfica tornará facilmente manifesto que a Filosofia do Conhecimento, enquanto tal, com os seus problemas específicos e as suas categorias próprias, não tem figurado, com uma assiduidade à medida da sua representatividade, na agenda daqueles que se dedicam à interpretação das proposta...

Le volume que nous présentons ici est le résultat d’un travail collectif entrepris pour la première fois exclusivement sur la notion de reprise, telle que l’a proposée Eric Weil (1904-1977), par des chercheurs venus du Portugal, de France, du Brésil, d’Italie, de Roumanie, du Burkina Faso et du Chili. Né en Allemagne, Eric Weil a étu­dié avec Ernst Cassirer qui l’a dirigé sur des recherches concernant les philosophes de la Renaissance, comme Pietro Pomponazzi et Marsile Ficin. Naturalisé fran...

Moral conflicts are the situations which emerge as a response to deal with conflicting obligations or duties. An interesting case arises when an agent thinks that two obligations A and B are equally important, but yet fails to choose one obligation over the other. Despite the fact that the systematic study and the resolution of moral conflicts finds prominence in our linguistic discourse, standard deontic logic when used to represent moral conflicts, implies the impossibility of moral conflicts. This presents a (...) conundrum for appropriate logic to address these moral conflicts. We frequently believe that there is a close connection between tolerating inconsistencies and conflicting moral obligations. In paraconsistent logics, we tolerate inconsistencies by treating them to be both true and false. In this paper, we analyze Graham Priest’s paraconsistent logic LP, and extend our examination to the deontic extension of LP known as DLP. We illustrate our work, with a classic example from the famous Indian epic Mahabharata, where the protagonist Arjuna faces a moral conflict in the battlefield of Kurukshetra. The paper aims to avoid deontic explosion and allows to accommodate Arjuna’s moral conflict in paraconsistent deontic logics. Our analysis is expected to provide novel tools towards the logical representation of moral conflicts and to shed some light on the context-sensitive paraconsistent deontic logic. (shrink)

Video streaming has become very popular among game enthusiasts. Live streams of computer games, where there is the possibility of communi­cation, are developing as community meeting places; a number of social scientists are calling this a trend towards new online “third places”. To­day’s debate draws attention to the reproduction of a participation culture trough streaming, in the space of which everyone can express themselves creatively, share their opinion, experiences, and information. At the same time, there is a tendency towards the (...) capitalist appropriation of streaming by media businesspersons who stimulate the monetization of participation. Investigating the “sociality of streaming”, the authors highlight the supplementation of the “Let’s Play” discourse with topics from the current agenda, understanding live streams as public media arenas. In the public arenas of computer game live streams, the dramatization and selection of global or local news information in a specific media format takes place. The article demonstrates this phenomenon using the example of the corona­virus, the most prominent topic of spring 2020. The pandemic vocabulary appears in different sections of Twitch game streams, such as titles, audio/ video content, and the chat. Banter and obscene vocabulary are charac­teristic of the game stream space, however, this is combined with charity fund-raising broadcasts in support of doctors. ­. (shrink)
