We consider various effects that are encountered in matter wave interference experiments with massive nanoparticles. The text-book example of far-field interference at a grating is compared with diffraction into the dark field behind an opaque aperture, commonly designated as Poisson’s spot or the spot of Arago. Our estimates indicate that both phenomena may still be observed in a mass range exceeding present-day experiments by at least two orders of magnitude. They both require, however, the development of sufficiently cold, intense and (...) coherent cluster beams. While the observation of Poisson’s spot offers the advantage of non-dispersiveness and a simple distinction between classical and quantum fringes in the absence of particle wall interactions, van der Waals forces may severely limit the distinguishability between genuine quantum wave diffraction and classically explicable spots already for moderately polarizable objects and diffraction elements as thin as 100 nm.

The European influences which after the discovery of America reshaped the cultural development of the New World, but also destroyed its previous identity are much better known than the components which re-influenced the way in which Europeans saw themselves. This asymmetry shows remarkable aspects. We notice that the early European descriptions of America do not consider the ancient cultures of America with their foreign and archaic traits, but that several hidden preconceptions prevail. These claims become evident in the discussion on (...) the "human nature" of the Indians, the "noble savage" and in the philosophical and theological controversies that accompanied the formation of the ius gentium. All this suggests that theses biases towards America have arisen from Europe's own problems. Therefore, it is not incorrect to say that in the discovery of the New World the Old World was re-discovered, too not only in its own prejudices, its desires, ideals and utopias, but also in the cruel practices of the conquerors, in genocide. The first European descriptions of America were made from the point of view of the Caravelle and not with the eyes of those who were waiting on land unsuspectingly, without weapons but with gifts.

Hybrid identities are sentences in a special second order language with identity. The model classes of sets of hybrid identities are called hybrid solid varieties. We give a Birkhoff-type-characterization of hybrid solid varieties and develop a hybrid equational logic.

We show that, in the partial ordering of the computably enumerable computable Lipschitz degrees, there is a degree a>0a>0 such that the class of the degrees which do not cup to a is not bounded by any degree less than a. Since Ambos-Spies [1] has shown that, in the partial ordering of the c.e. identity-bounded Turing degrees, for any degree a>0a>0 the degrees which do not cup to a are bounded by the 1-shift a+1a+1 of a where a+1 (...) that the elementary theories of the partial orderings and differ.

Appraisal theories of emotion have had a strong impact on the development of theory and experimental research in the domain of the affective sciences. While there is generally a high degree of convergence between theorists in this tradition, some central issues are open to debate. In this contribution three issues have been chosen for discussion: (a) varieties of relevance detection, (b) varieties of valence appraisal, and (c) sequential-cumulative effects of appraisal results. In addressing these issues, new theoretical ideas are suggested (...) and an update of recent research on the sequence of appraisal processes is provided. Special emphasis is placed on nonverbal signatures of appraisal processes. (shrink)

The location of verbally reported feelings in a three-dimensional affective space is determined by the results of appraisal processes that elicit the respective states. One group of participants rated their evaluation of 59 pictures from the International Affective Picture System (IAPS) on a profile of nine appraisal criteria. Another group rated their affective reactions to the same pictures on the classic dimensions of affective meaning (valence, arousal, potency). The ratings on the affect dimensions correlate differentially with specific appraisal ratings. These (...) results can be interpreted as showing that the reactions to the IAPS pictures are predictably produced through appraisal of picture content. The relevance of the findings for emotion induction paradigms and for emotion theory in general is discussed. (shrink)

Following Yik and Russell (1999) a judgement paradigm was used to examine to what extent differential accuracy of recognition of facial expressions allows evaluation of the well-foundedness of different theoretical views on emotional expression. Observers judged photos showing facial expressions of seven emotions on the basis of: (1) discrete emotion categories; (2) social message types; (3) appraisal results; or (4) action tendencies, and rated their confidence in making choices. Emotion categories and appraisals were judged significantly more accurately and confidently than (...) messages or action tendencies. These results do not support claims of primacy for message or action tendency views of facial expression. Based on a componential model of emotion it is suggested that judges can infer components from categories and vice versa. (shrink)

Immanuel Kant has built up a dualistic epistemology that seems to fit to the peculiarities of chemistry quite well. Friedrich Paneth used Kant’s concept and characterised simple and basic substances which refer to the empirical and to the transcendental world, respectively. This paper takes account of the Kantian influences in Paneth’s philosophy of chemistry, and discusses pertinent topics, like observables, atomism and realism.

ArgumentKuhnian phases of paradigmatic development correspond to characteristic variations of citation measures. These correlations can in turn be predicted from a simple model of human information processing when applied to the common environments of scientists. By combining a scientometric and a human information processing approach to the history of scientific thought, structures of disciplinary development, and in particular paradigmatic cycles, can be more reliably assessed than before. Consequently, the quantitative historian of science is liberated to some extent from the vagaries (...) of qualitative judgment, as exemplified by traditional narrative type approaches to the history of science.

Emotion regulation, and in particular cognitive reappraisal. Gross has been booming in theory development and empirical research for the last two decades. A large number of publications have demonstrated the importance of these mechanisms for understanding and promoting well-being and mental health. It is thus timely for Cognition and Emotion to examine the current state of theory in this domain. The resultant invited article, authored by Uusberg, A., Ford, Uusberg, H., and Gross, aims to expand the scope of reappraisal theory (...) by extending their recent reAppraisal model by suggesting different forms of goal commitment and situation construals. Their suggestions are commented on by Kashdan and Goodman from a purpose in life perspective, Ehring, and Woud from a clinical psychopathology perspective. In this editorial, I briefly discuss the lack of specification of the goal construct, which is central to the reappraisal model. Moreover, I point to recent evidence showing that problems may arise because of appraisal biases, in the case of individuals prone to inappropriate evaluations of situations. I suggest that future work in this domain could benefit from increased interaction between theorists and researchers working on appraisal and reappraisal processes. (shrink)

Diagnosing emotion disturbances should be informed by current knowledge about normal emotion processes. I identify four major functions of emotion as well as sources for potential dysfunctions and suggest that emotions should only be diagnosed as pathological when they are clearly dysfunctional, which requires considering eliciting events, realistic person-specific appraisal patterns, and adaptive responses or action tendencies. Evidence from actuarial research on the reported length of naturally occurring emotion episodes (including potential determinants) illustrates appropriateness criteria for the clinical evaluation of (...) emotion duration—an essential element in the DSM-5 symptom catalogue for major depression episodes, especially in bereavement. The need for more actuarial evidence on normal emotion responses and its consideration by the clinical community is highlighted. (shrink)

I strongly endorse many of the suggestions made by the authors of the extremely useful reviews in this issue. In particular, the need to identify the complex causal mechanisms underlying the major health risk factors requires urgent attention of the research community. I suggest considering the important role of emotional disturbances as contributors to health risks given the empirically established comorbidity between mental and somatic illness. Better knowledge of these mechanisms is an essential prerequisite to develop tailored personalized prevention and (...) intervention programs, including reliable and valid assessment of deficits.

The dynamic development of science and technology in the last decades has led to new challenges in jurisprudence. This holds for individual fields of doctrinal law as well as the concerned fields of jurisprudence. It is especially significant for the structure of justice, the efficiency of law as a steering instrument of society, and the empirical conditions of legal responsibility. In a jurisprudential perspective, the philosophy of law is rather engaged with the adaptiveness of its traditional principles and categories or (...) the capacity to come to terms with the new developments and less concerned with concrete matters of law.

Does the soul have parts? What kind of parts? And how do all the parts make together a whole? Many ancient, medieval and early modern philosophers discussed these questions, thus providing a mereological analysis of the soul. Their starting point was a simple observation: we tend to describe the soul of human beings by referring to different types of activities (perceiving, imagining, thinking, etc.). Each type of activity seems to be produced by a special part of the soul. But how (...) can a simple, undivided soul have parts? Classical thinkers gave radically different answers to this question. While some claimed that there are indeed parts, thus assigning an internal complexity to the soul, others emphasized that there can only be a plurality of functions that should not be conflated with a plurality of parts. The eleven chapters reconstruct and critically examine these answers. They make clear that the metaphysical structure of the soul was a crucial issue for ancient, medieval and early modern philosophers. (shrink)

Klaus Mainzer legt in diesem essential dar, dass die Zukunft von KI und Digitalisierung eine nüchterne Analyse erfordert, die Grundlagenforschung mit Anwendung verbindet. Berechenbarkeits- und Beweistheorie können dazu beitragen, Big Data und Machine Learning sicherer zu bewältigen. Dabei zeigt sich, dass die komplexen Herausforderungen der digitalen und analogen Welt in Grundlagenfragen der Mathematik, Informatik und Philosophie tief verwurzelt sind.

Die besonderen Bedingungen der griechischen Sprache und ihrer langen Geschichte seit den Zeiten Homers haben schon seit der klassischen Epoche und zunehmend im Hellenismus und der Kaiserzeit Probleme der korrekten Akzentuierung und Orthographie aufgeworfen. Zumal die gelehrten hellenistischen und kaiserzeitlichen Editoren und Interpreten der homerischen Gedichte und anderer frühgriechischer und klassischer Poesie mußten zu unzähligen strittigen Fragen des Akzents und der richtigen Schreibung Stellung beziehen. Im 2. Jahrhundert n. Chr. hat der aus Alexandreia gebürtige, in Rom tätige Grammatiker Ailios Herodianos (...) über beide Bereiche umfassende Bücher verfaßt. Auf Aufforderung Kaiser Mark Aurels (und diesem gewidmet) schrieb er sein gewaltiges Hauptwerk in 21 Büchern, die Καθολιϰη πϱοσωδία („Allgemeine Akzentlehre“) und ebenfalls ein umfangreiches Buch Πεϱι οϱθογϱαϕίας. Beide sind wie alle seine anderen Werke bis auf die Schrift Πεϱι μονήϱους λέξεως verloren. Mit geradezu herodianischem Fleiß hat A. Lentz eine Rekonstruktion des Verlorenen unternommen. Man muß leider sagen, daß die Zeit für eine solche Rekonstruktion noch nicht reif war; einerseits mußte Lentz für fast alle Quellschriften auf Editionen zurückgreifen, die auf völlig unzureichender handschriftlicher Basis erstellt waren, andererseits konnte er noch nicht die spektakulären Handschriftenfunde R. Reitzensteins und die daraus resultierenden umstürzenden Ergebnis zur Kenntnis nehmen. „Es liegt eine Tragik darin, daß ein unter den größten Schwierigkeiten geleistetes Lebenswerk durch die Fahrlässigkeit der Herausgeber, deren Leistungen Lentz zugrunde legen mußte, von vornherein auf ungenügendem Fundament ruhte.“ Sowohl für den Bereich der Akzentlehre („Orthoepik“) wie den der Orthographie der Spätantike und der byzantinischen Zeit hat Peter Egenolff in zwei bahnbrechenden Schulprogrammen einen Überblick über die unzähligen Traktate in der Nachfolge Herodians und die sie tradierenden Handschriften geliefert. Egenolffs Arbeiten sind naturgemäß stark veraltet, da zahlreiche Handschriften erst nach ihm bekannt wurden und sehr viele neue Erkenntnisse auf dem Gebiet der griechischen Grammatik und Lexikographie seither erzielt worden sind. Aber Egenolffs Sammlungen und Überblicke sind bisher nicht überholt worden und werden auch für das Gebiet der Orthographien durch das hier zu behandelnde Werk leider nicht wirklich ersetzt. (shrink)

Thema der kleinen und bemerkenswerten Spätschrift des Aristoteles ist die Beantwortung der Frage ›Wie bewegt die Seele den Körper?‹, d.h. der Frage nach dem Auslöser der Selbstbewegung von Lebewesen. Dies beinhaltet alle gewollten oder auch ungewollten Akte der Selbstbewegung animalischer und menschlicher Organismen. Damit steht die Schrift in der Mitte zwischen der allgemeinen Bewegungslehre des Aristoteles und der in seinen früheren Schriften abgehandelten Biologie und Psychologie, auf die er hier häufig zurückgreift. In 'De motu' wird eine umfassende biologische Theorie des (...) animalischen und menschlichen Handelns formuliert, die handlungstheoretischen und physiologischen Fragen gleichermaßen gerecht zu werden sucht. Auch äußert Aristoteles sich darin erstmals zum berühmten ›angeborenen Pneuma‹, in dem er eine vermittelnde Instanz in der Bewegungsübertragung sieht. Diese Ausgabe bietet die Schrift, die seit der Edition von Martha Nussbaum (1978) in den Blickpunkt der Forschung geraten ist, in einer Neuedition des griechischen Originaltextes von Oliver Primavesi und in einer neuen deutschen Übersetzung und Erläuterung von Klaus Corcilius. Der griechische Text konnte an vielen Stellen durch die Heranziehung des zweiten selbstständigen Überlieferungszweiges verbessert werden, der allen früheren Herausgebern unbekannt geblieben war und den Oliver Primavesi 2011 auf dem 19. Symposium Aristotelicum zu 'De motu' vorgestellt hat. (shrink)
