The contributions in this paper are in two folds. On the one hand, we propose a general approach for approximating ideal filters based on fractional calculus from the point of view of systems of fractional order. On the other hand, we suggest that the Paley and Wiener criterion might not be a necessary condition for designing physically realizable ideal filters. As an application of the present approach, we show a case in designing ideal filters for suppressing 50-Hz interference in electrocardiogram (ECG) signals.

Abstract The logic of evidence in Bartolistic literature, A reading of the Summa circa testes et examinationem eorum (Ms. Bruxelles, B.R., II 1442, fol.101 ra – 103 rb). – Bartolus teaches how to read testimonies from a logical point of view. On the one hand, the facts that the witness recounts constitute the minor premise of a syllogism, its conclusion being their legal characterization; therefore he is prohibited from pronouncing directly on any legal matter. On the other hand, given that the witness' knowledge of the facts has to stem from sensory perception, the information he provides has at least to constitute the minor premise of another syllogism, making for establishing the causa of his testimony.

Rosemberg (1991) has made a critical review of a long-standing discussion between Eastern philologists and Buddhist philosophers. The discussion is centered around the translation of the doctrine on the one hand, and its philosophical systematization on the other hand. When scientific-philological translation prevails, the literal meaning of Buddhist terminology is declared to be its basis. The young scholar, who had specialized in Japan, studied Buddhism from Japanese and Chinese sources and collected lexicographic material from non-Hindu sources. After comparing them, he encountered inaccuracies in the translation. In an attempt to overcome them, he preferred the point of view of the philosophy of Buddhism. The conclusion that he has drawn in the preface of this edition is that the study should begin with a systematization of antiquity.

This article examines the problem of overcoming nihilism in Heidegger’s dialogue with Jünger. It is suggested that nihilism is manifested in various forms and is the deep logic of the whole history of European civilization. One of the main aims of this paper is to outline the relationship of nihilism and Nothing in Heidegger’s dispute with Jünger, viewing how Heidegger distinguishes his approach from Jünger’s point of view. Heidegger, on the one hand, treats nihilism as consummation of the Western metaphysical tradition, on the other hand, identifies Nothing itself as the shadow of Being, which cannot be overcome in the traditional dialectical thinking manner.

Over the course of its history, design has never lost sight of nature as a term of comparison, sometimes taking from it, sometimes moving away from it. To investigate the complex relationship between the two terms, design and nature, we cannot ignore the evolution of man and how it has been profoundly influenced by technological innovation, which is the most evident result of science. Tracing an evolutionary line of design thinking, a double trajectory can be registered: on the one hand the tension towards progress and the myth of the machine, on the other hand the idea of a harmonious co-evolution with nature and the need to be reconnected with it. Besides, it is progress that allows mankind to thoroughly investigate natural mechanisms and make them their own. Contemporary design, autonomous but at the same time increasingly interdisciplinary, has got blurred boundaries which intersect with the most advanced fields of biological sciences. This evolution has opened up a whole new field of investigation that multiplies the opportunities of innovation, especially from a sustainability-oriented point of view. Today the dramatic breaking of the balance between man and nature has turned into the concept of permanent emergency, which is now matter of greatest interest for design, a design that attempts to react, mend, adapt to change in an authentically resilient way.

This article aims at analysing René Maran’s five animal novels. In these texts, Maran criticizes the colonial system not only for its cruelty to the native population, but also for its ecological violence against the bush and its non-human inhabitants. In particular, this research will be focusing on the author’s ability to abandon a human (and colonial) point of view in order to adopt an animal one. On the one hand, this new subjectivity – as well as Maran’s comprehension of indigenous naturalist society – allows the writer to condemn the colonial period from an ecocritical perspective. On the other hand, it provides evidence of the existence of culture among the beasts of his novels. Finally, this article will also prove that it is thanks to their culture that Maran’s animals will try to resist the colonial-centred environment and ideology.

The article presents the letters of Sidonius Apollinaris - Gallo-Roman aristocrat, poet and bishop. The study aims at analysing the letters of Sidonius from the point of view of their purpose, the models used, the argumentation, and the list of recipients to whom the letters are addressed. On the one hand, it shows that Sidonius remained faithful to his masters in epistolography (Cicero, Pliny the Younger, Symmachus), while on the other hand, was able to change the form of letters according to the situation. The paper also allows us to discern the changes that took place in the works of Sidonius after his ordination.

Opening ParagraphFew of the secrets that Africa still holds from us to-day have, I think, such an absorbing interest as the problem of Bantu in its relation to the neighbouring families and types of speech. Taking the continent of Africa as a whole, we find on the one hand the huge, yet marvellously homogeneous and compact body of the Bantu languages, clear-cut in structure, simple and transparent in phonology, and, at the back of much apparent diversity, exceptionally uniform in vocabulary. On the other hand there are in Africa numerous other languages of various type, which differ so much amongst each other that they have not yet been brought under any but the very broadest of classifications. The essential points of these are as follows.

Chaplains in penal times were on occasion employed as stewards, though perhaps not as frequently as is sometimes supposed; from the point of view of their employers this is not entirely surprising; on the one hand chaplains might reasonably be expected to be literate, numerate and honest; on the other hand the restrictions under which Catholic priests worked might well leave them a sufficiency of spare time for secular affairs. The interest of the letter which follows lies not in the mere fact of such a stewardship, but in the extraordinarily vivid picture it gives of what it was like for a professed Religious to be involved in running an estate—particularly when his employer was of questionable sanity. Some light is incidentally thrown on the history of Catholicism in Linton-on-Ouse.

InLeibniz: Perception, Apperception, and Thought, Robert McRae alleges a flat “contradiction” (McRae 1976, p. 30) at the heart of Leibniz's doctrine of three grades of monads: bare entelechies characterized by perception; animal souls capable both of perception and of sensation; and rational souls, minds or spirits endowed not only with capacities for perception and sensation but also with consciousness of self or what Leibniz calls (introducing a new term of art into the vocabulary of philosophy) “apperception.” Apperception is a necessary condition of those distinctively human mental processes associated with understanding and with reason. Insofar as it is also a sufficient condition of rationality, it is not ascribable to animals. But apperception is a necessary condition of sensation or feeling as well; and animals are capable of sensation, according to Leibniz, who decisively rejected the Cartesian doctrine that beasts are nothing but material automata. “On the one hand,” writes McRae, “what distinguishes animals from lower forms of life is sensation or feeling, but on the other hand apperception is a necessary condition of sensation, and apperception distinguishes human beings from animals” (McRae 1976, p. 30). “We are thus left with an unresolved inconsistency in Leibniz's account of sensation, so far as sensation is attributable both to men and animals” (ibid., p. 34).

The goal of the present paper was to investigate whether soccer referees’ nonverbal behavior (NVB) differed based on the difficulty of their decisions and whether perceivers could detect these systematic variations. On the one hand, communicating confidence via NVB is emphasized in referee training. On the other hand, it seems feasible from a theoretical point of view that particularly following relatively difficult decisions referees have problems controlling their NVB. We conducted three experiments to investigate this question. Experiment 1 (N = 40) and Experiment 2 (N = 60) provided evidence that perceivers regard referees’ NVB as less confident following ambiguous decisions as compared with following unambiguous decisions. Experiment 3 (N = 58) suggested that perceivers were more likely to debate with the referee when referees nonverbally communicated less confidence. We discuss consequences for referee training.
