Ray splitting is a universal phenomenon that occurs with appreciable amplitude in all wave systems when the properties of the system change on a scale smaller than the wave length. We study the quantum implications of ray splitting theoretically and experimentally with the help of ray-splitting billiards in one and two dimensions. We show that Gutzwiller's trace formula works even in the context of ray-splitting systems provided reflection and transmission of waves at ray-splitting boundaries is properly included.

Pakṣilasvāmin's introduction to his Nyāyabhāṣyam is perhaps one of the most interesting texts of the older Nyāya indispensable to the understanding of the system. This is not because the ideas expressed therein were not to be surpassed at a later period, but because in it the development of the school appears fixed, as it were, in a "transitory moment" (transitorisches Moment), and we see there for the first time that line of thought, which historically took form in the Nyāya philosophy, (...) becoming aware of itself in a clear, though archaic, manner. Furthermore, if we bear in mind to what extent such an interpretation of a school (given by itself) determines its development, the importance of Pakṣilasvāmin's text for the history of Nyāya cannot be over-estimated.

The authors work in a variety of clinical ethics consultation services (CECSs) that employ a range of methods and approaches. This article discusses the approach to ethics consultation at the Center for Medical Ethics and Health Policy at Baylor College of Medicine and describes the development and transformation of the authors’ CECSs. It discusses how one CECS shifted from a nascent program with only fifty consultations a year to a vibrant, heavily staffed service with five hundred ethics consultations a year.

Nelson Goodman (1906-1998) was one of the outstanding thinkers of the 20th century. In a memorial note, Hilary Putnam considers him to be ""one of the two or three greatest analytic philosophers of the post-World War II period"". Goodman has left his mark in many fields of philosophical investigation: Epistemology, Philosophy of Science, Logic, Metaphysics, the General Theory of Symbols, Philosophy of Languageand Philosophy of Art, all have been challenged and enriched by the problems he has shown up, the projects (...) he developed from them and the solutions he has suggested. In August 2006 a coup. (shrink)

The recent financial crisis has triggered an intense debate about the role of banks in society, presumably changing the criteria used in the evaluation of organizations. Against this backdrop, we investigate the changing role of banks’ organizational features in shaping different dimensions of banks’ organizational reputation. Using the media as an important evaluator, we measure the reputational dimension of visibility based on the frequency of newspaper articles and the reputational dimension of favorability based on the sentiment of newspaper articles. Drawing (...) on social judgment research for developing our hypotheses, we expect that organizational features such as financial performance and familiarity become more important determinants of organizational reputation in times of crisis. Our results support this expectation, suggesting stronger effects of these organizational features on the visibility and favorability of banks during a crisis. These findings provide novel empirical evidence on how the importance of drivers of organizational reputation changes in times of crisis and highlight areas for managerial attention. (shrink)

A study of the analogies between alchemy, Christian dogma, and psychological symbolism. Revised translation, with new bibliography and index.

Self-, collective, and participative efficacy are strong predictors of sustainability action. Yet, few studies have investigated the dynamics and variability of efficacy beliefs. In this transdisciplinary study, we tested such factors in the context of a peer-to-peer coaching program for sustainability volunteers, embedded in a structured-educational context. Over weekends, 2 qualified coaches trained 36 German bottom-up, student-led sustainability initiatives. These coaches instructed students in team building, envisioning, project planning, and on-campus sustainability practice. While 317 participants completed our pre-questionnaire, N = (...) 165 completed both the pre- and post-questionnaire. As hypothesized, after having participated in the coaching weekend, action skills, collaboration skills, group identification, and self-, collective, and participative efficacy all increased. The latter of these increased, to our knowledge, for the first time in environmental psychology research. Group identification and having a vision emerged as important efficacy predictors, and participative efficacy beliefs in turn predicted volunteering. Moreover, we took initial steps in investigating the interaction of psychological and structural factors from a multilevel perspective. Our analyses revealed that efficacy beliefs on the individual level were higher when the university had a green office and when the student initiative was at a small university. We conclude by proposing an empowerment model for sustainability volunteers and by discussing the practical implications of our findings. (shrink)

Infertility is an unpredictable but widespread condition. While high‐income countries grapple with when, or how to cover the costs of assisted reproductive technology (ART), such as in‐vitro fertilisation (IVF), these services are generally only available to wealthy persons at private facilities in low‐ and middle‐income countries (LMICs). Although the principle of non‐interference with normal individual reproductive rights is robust, whether it is also the responsibility of collective society to provide the means (when ART applies) to achieve pregnancy, is controversial. Recently, (...) a low‐cost model was developed at a South African public institution. The target population for this model was “helpless and marginalised, childless couples”, but a new threat has arisen, namely, infertile couples who could conceivably afford private care. In the allocation of this scarce resource, we argue for a prioritarian response that first addresses the worst‐off, in order to even out unequal access imposed by sharp differences in income.

Der Titel Eudämonie verspricht Schönes, Angenehmes, Erbauliches, und alles das will und soll dieses Buch auch leisten. Wer von uns wünschte sich nicht ein gutes und gelingendes Leben, ohne allerdings so mir nichts, dir nichts sagen zu können, woraus denn dieses Gute, Schöne und Wahre besteht. Wer von uns kennt nicht den intensiven Wunsch nach Glück und Zufriedenheit, und wem begegneten bei seiner oder ihrer Suche nach Glück und Zufriedenheit aber nicht schon Hürden und Herausforderungen aller Art, die uns bisweilen (...) rat- und hilflos haben werden lassen? Allein schon aufgrund dieser persönlichen Kalamitäten, die jeder von uns oftmals zu gewärtigen hat, scheint es gerechtfertigt, über Eudämonie und damit über die Möglichkeiten eines gelingenden Lebens nachzudenken. Leben zwischen... Kunst und Spiel / Ich und Du / verbaler Sprache und beredtem Leib / Vergangenheit und Zukunft / Kontemplation und Tat / Sinnlichkeit und Form.

Zusammenfassung In deutschen Privathaushalten sind derzeit schätzungsweise 100.000 bis 500.000 in Pendelmigration lebende Live-in-Hilfen tätig, viele von ihnen in der Versorgung von Menschen mit Demenz. Dabei deutet die primär sozialwissenschaftlich ausgerichtete Forschung zu Live-in-Versorgung auf vielfältige strukturell bedingte Missstände hin. Allerdings fehlt bislang eine eingehendere ethische Analyse und Erörterung mit Blick auf das Mikrosetting der betreffenden Versorgungsarrangements selbst. Der vorliegende Artikel geht der Frage nach, welche moralischen Probleme und Konflikte im Mikrosetting häuslicher Live-in-Versorgung von Menschen mit Demenz auftreten und wie (...) diese ethisch einzuschätzen sind. Zu diesem Zweck werden im Zuge einer qualitativen Inhaltsanalyse von 182 Beiträgen aus drei deutschsprachigen Onlineforen die Ansprüche betroffener Angehöriger von Menschen mit Demenz gegenüber Live-in-Hilfen herausgearbeitet und ethisch eingeordnet. Wie sich zeigt, werden diese als Dienstleistungserbringer:in, Pflegekraft, moralische:r Akteur:in und Familienmitglied adressiert. In den vielfältigen und häufig enttäuschten Erwartungen der Angehörigen treten teils problematische und widersprüchliche Ansprüche gegenüber Live-in-Hilfen zu Tage. Eine ethische Analyse ihrer Legitimität und Kohärenz kann zur Verbesserung der individuellen Planung und Gestaltung, der institutionellen Organisation sowie der gesellschaftlichen Verständigung und rechtlichen Regulierung von Live-in-Versorgung beitragen.
