Objectives: The COVID-19 pandemic is having a major impact on the lives of everyone, but in particular on the health and well-being of older people. It has also disrupted the way that individuals access services and interact with one another, and physical distancing and “Stay at Home” orders have seen digital interaction become a necessity. While these restrictions have highlighted the importance of technology in everyday life, little is known about how older adults have responded to this change. Methods: Two (...) surveys, one in 2019 and another in 2020 collected data on a combined total of 1923 older adults aged 65 years and older in Canada. These looked at how older adults think about and use technology, with the 2020 survey additionally questioning how COVID-19 has impacted their use and attitudes towards technology. Results: While older adults feel more isolated in 2020, many feel positive about the benefits of technology and have increased technology use during the pandemic to support their health, wellness, and communication needs. Discussion: The results highlight the potential of technology for supporting older adults in various aspects of healthy aging. While these results point to the opportunities afforded by technology, challenges remain, such as how social and economic factors influence technology uptake. (shrink)

In light of the atrocities of National Socialism, the challenge of working through the past has become a crucial issue. The end of Communism has reinforced the urgency of this challenge. Coming to terms with an ethically problematic past takes place at several levels (jurisdictional/legal, political, mental). A central challenge is to keep memory alive and thereby to gain appropriate insights. However, the demand for constructive forms of remembrance should not be overloaded with expectations that are impossible to meet. The (...) acceptance of guilt or responsibility requires an atmosphere of mercy and forgiveness, and is threatened by impatience. In this context, historical research can be seen as a form of ‘pathological inquiry’ into time and the past, providing mental and moral orientation for the present generation of humans; reflection about the past may be an important aspect of tackling the challenge of the present. Such historical research must always critically assess its own interest and beware of a drift towards becoming ideological grounded in a certain kind of moralism. The one who sees the light of the Promise of Easter above the graves of the past can conclude, following Cordelia Edvardson: ‘The past is at our mercy’. (shrink)

Shaping the Future maps out the ascetic practices of a Neitzschean way of life. Hutter argues that Nietzsche's doctrines are attempts and "temptations" that aim to provoke his free-spirited readers into changing themselves by putting philosophy into practice in their lives.

Fifty years ago Hartman studied the barrier transmission time of wave packets (J Appl Phys 33:3427–3433, 1962). He was inspired by the tunneling experiments across thin insulating layers at that time. For opaque barriers he calculated faster than light propagation and a transmission time independent of barrier length, which is called the Hartman effect. A faster than light (FTL or superluminal) wave packet velocity was deduced in analog tunneling experiments with microwaves and with infrared light thirty years later. Recently, the (...) conjectured zero time of electron tunneling was claimed to have been observed in ionizing helium inside the barrier. The calculated and measured short tunneling time arises at the barrier front. This tunneling time was found to be universal for elastic fields as well as for electromagnetic fields. Remarkable is that the delay time is the same for the reflected and the transmitted waves in the case of symmetric barriers. Several theoretical physicists predicted this strange nature of the tunneling process. However, even with this background many members of the physics community do not accept a FTL signal velocity interpretation of the experimental tunneling results. Instead a luminal front velocity was calculated to explain the FTL experimental results frequently. However, Brillouin stated in his book on wave propagation and group velocity that the front velocity is given by the group velocity of wave packets in the case of physical signals, which have only finite frequency bandwidths. Some studies assumed barriers to be cavities and the observed tunneling time does represent the cavity lifetime. We are going to discus these continuing misleading interpretations, which are found in journals and in textbooks till today. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:THE CONCEPT OF PERSON IN ST. THOMAS AQUINAS: A Contribution to Recent Discussion* ST. THOMAS AQUINAS accepted and consistently defended Boethius' definition of person: "persona est substantia individua rationalis naturae." St. Thomas' analysis of this definition necessarily involves metaphysical questions because of the implications of the terms " substance" and " nature" and moreover it manifests the inescapahle imprint of the theological problematics which surrounded the issue (e.g. the (...) Trinity and the hypostatic union). Both of these influences, metaphysical and theological, have engendered problems of interpretation and criticism. Contemporary discussions of person largely either continue the scholastic controversies or adopt a modern perspective from which to expose apparent contradictions in St. Thomas' doctrine. The purpose of this article will be limited to a consideration of the metaphysical problems concerning the relationship between individual substance, universal, nature, and existence. It is hoped that such a clarification will resolve not only the neoscholastic controversies, but also some of the contemporary problems. I. BOETHIUS' DEFINITION OF PERSON AND ST. THOMAS' EXPLANATION A.

He adapted the version in good style and verified the Latin quotations. 435 436 HORST SEIDL ture and substance.1 In the first chapter he sets out to define nature and discovers four possible meanings. The first and broadest definition, embracing both substances and accidents, describes nature as belonging to all things which by their being can be in some way or another be comprehended by reason: "natura est earum rermn quae, cum sint, quoquo modo intellectu capi possunt." A second definition, comprising substances alone both corporeal and incorporeal, describes nature as anything that can effect or suffer something: " natura est vel quod facere vel quod pati possit." A third sense, taken from the Aristotelian analysis of the motion of natural substances, describes nature as the immanent principle of movement : "natura est motus principium per se et non per accidens." Finally, nature can also refer to the formal cause which provides the specific difference: " natura est unam quamque rem informans specifica differentia" (cf. ST Ia. 29, I ad 4). It is this last sense which is most important. In sum, "nature" is a broad term encompassing both composite beings and their causes. Boethius continues in chapter two by first narrowing the relevant sense of nature to substances (thus excluding accidents ) and then presenting a complete division of substances. The major distinction is between corporeal substances and incorporeal substances. Corporeal subdivides further into inanimate and animate, with animate dividing. into insensitive and sensitive and the latter dividing finally into irrational and rational. Incorporeal subdivides into rational and irrational (the life-principle of animals), with rational incorporeal substances being further distinguished into those that are immutable by nature (the Creator) and those that are not so by nature (the human soul and angels) but may become so by virtue of the immutable substance. Boethius then argues that person cannot be affirmed of inanimate beings or irrational animals.

Rand (Cambridge: Harvard University Press, 1918). THE CONCEPT OF PERSON IN ST. THOMAS AQUINAS 437 final distinction of :substance into universal and particular leads to the conclusion that person must refer to an individual. Thus the background is set for the definition of person which opens the third chapter: " naturae rationalis individua substantia." Person must be an individual substance of a certain nature, namely rational, which nature accounts for the form or specific difference of the particular substance (the fourth meaning of chapter 1). The connection of this definition with Aristotle 's definition of man as a rational animal is unmistakable. It should also be noted that this definition of person is applicable not only to man, in whom the rational nature is not identical with his substance, but also to the... (shrink)

English summary: What does Dada mean? The answer lies in the distinction between the perceptible and the designation and the failure to mediate discursively between the two. With the inception of Dada-Zurich - at the intersection between literary and art studies, comparative studies, image-text theory and philosophy - the relationship between modernity and avant-garde as well as between avant-garde and Dadaism was redefined. This redefinition was a consequence of the scandalous aesthetic theoretical insights of Dada Zurich, which concretized in practical (...) and poetic form an aesthetic theory that in itself is aesthetic, and developed an aesthetic-theoretical understanding in which aisthesis takes up a central position. Dada uses the avant-garde as material. The aesthetic theoretical potential of Dada Zurich in turn had an impact not only on the artefacts that were actually used and aesthetically reflected by Dada, but on all modern - including avant-garde - artefacts. German description: Was bedeutet Dada? Die Antwort liegt in der Differenz von Wahrnehmbarem und Bezeichnung und deren scheiternder diskursiven Vermittlung. Mit der Konstitution des Gegenstandes Dada-Zurich - im Schnittfeld von Literatur- und Kunstwissenschaft, Komparatistik, Bild-Text-Theorie und Philosophie - wird das Verhaltnis von Moderne und Avantgarde sowie von Avantgarde und Dada neu bestimmt. Diese Neubestimmung resultiert aus der Erkenntnis der asthetisch-theoretischen Form Dada-Zurichs, deren Konstitution das theoretische Skandalon Asthetischer Theorie (als einer Theorie, die selber asthetisch wird) in praktischer und poietischer Form konkretisiert. Sie entwickelt eine asthetisch-theoretische Erkenntnisform, in der Aisthesis eine zentrale Stellung einnimmt. Dada nutzt die Avantgarde als Material. Das asthetisch-theoretische Potential Dada-Zurichs wirkt dabei nicht nur zuruck auf die von Dada tatsachlich verwendeten (asthetisch reflektierten), sondern auf alle modernen - auch avantgardistischen - Artefakte.

Shepard's internalization concept is defended against Hecht's criticisms. By ignoring both Shepard's evolutionary perspective and the fact that internalization does not preclude modularization, Hecht advances inconclusive evidence. Developmental research supports Shepard's conclusion that kinematic geometry may be more deeply internalized than physical dynamics. This research also suggests that the internalization concept should be broadened to include representations acquired during ontogeny. [Hecht; Shepard].

La cuestión hermenéutica, es decir las cuestiones filosóficas que tratan del problema de la comprensión y de la interpretación de textos, de comportamientos sociales y de culturas ajenas, es con certeza uno de los problemas fundamentales del pensamiento filosófico del siglo XX. Filósofos tan distintos como Heidegger y Habermas, Gadamer y Derrida, para sólo mencionar algunos, tienen este cuestionamiento como punto común. La relevancia de este tema para la filosofía actual fue motivo para elaborar en este seminario dos posiciones fundamentales (...) en el contexto de esta discusión, representadas por la filosofía de Wilhelm Dilthey y de Friedrich Nietzsche.
