We consider several puzzles of bounded rationality. These include the Allais- and Ellsberg paradox, the disjunction effect, and related puzzles. We argue that the present account of quantum cognition—taking quantum probabilities rather than classical probabilities—can give a more systematic description of these puzzles than the alternate treatments in the traditional frameworks of bounded rationality. Unfortunately, the quantum probabilistic treatment does not always provide a deeper understanding and a true explanation of these puzzles. One reason is that quantum approaches introduce additional (...) parameters which possibly can be fitted to empirical data but which do not necessarily explain them. Hence, the phenomenological research has to be augmented by responding to deeper foundational issues. In this article, we make the general distinction between foundational and phenomenological research programs, explaining the foundational issue of quantum cognition from the perspective of operational realism. This framework is motivated by assuming partial Boolean algebras. They are combined into a uniform system via a mechanism preventing the simultaneous realization of perspectives. Gleason’s theorem then automatically leads to a distinction between probabilities that are defined by pure states and probabilities arising from the statistical mixture of pure states. This formal distinction relates to the conceptual distinction between risk and ignorance. Another outcome identifies quantum aspects in dynamic macro-systems using the framework of symbolic dynamics. Finally, we discuss several ideas that are useful for justifying complementarity in cognitive systems. (shrink)

Explores some steps toward non-assimilative encounters in the "global village.".

Als atmospharisch bergendes Gefuhl steht Heimat in einem fruchtbaren Spannungsfeld vielfaltiger gesellschaftlicher Einflusse. In Zeiten der Globalisierung verandern sich die Voraussetzungen fur die Konstitution von Heimat insbesondere durch Mobilitat, Migration, soziale Unsicherheit und Ideologisierung. Die Beitrage des Bandes diskutieren das Spannungsfeld von Eigenem und Fremdem aus verschiedenen theoretischen Perspektiven. Mit Beitragen von Amalia Barboza, Gernot Bohme, Simone Egger, Jurgen Hasse, Karen Joisten, Reinhard Knodt, Hermann Schmitz, Carolin Stapenhorst und Nina Trcka.

This article provides the proof-theoretic analysis of the transfinitely iterated fixed point theories $\widehat{ID}_\alpha and \widehat{ID}_{<\alpha};$ the exact proof-theoretic ordinals of these systems are presented.

Clinical ethics support services are experiencing a phase of flourishing and of growing recognition. At the same time, however, the expectations regarding the acceptance and the integration of traditional CES services into clinical processes are not met. Ethics rounds as an additional instrument or as an alternative to traditional clinical ethics support strategies might have the potential to address both deficits. By implementing ethics rounds, we were able to better address the needs of the clinical sections and to develop a (...) more comprehensive account of ethics quality in our hospital, which covers the level of decisions and actions, and also the level of systems and processes and aspects of ethical leadership.

Bunnik and colleagues argued that financial barriers do not promote informed decision-making prior to prenatal screening and raise justice concerns. If public funding is provided, however, it would seem to be important to clarify its intentions and avoid any unwarranted appearance of a medical utility of the testing.

In the absence of pre‐established communicative conventions, people create novel communication systems to successfully coordinate their actions toward a joint goal. In this study, we address two types of such novel communication systems: sensorimotor communication, where the kinematics of instrumental actions are systematically modulated, versus symbolic communication. We ask which of the two systems co‐actors preferentially create when aiming to communicate about hidden object properties such as weight. The results of three experiments consistently show that actors who knew the weight (...) of an object transmitted this weight information to their uninformed co‐actors by systematically modulating their instrumental actions, grasping objects of particular weights at particular heights. This preference for sensorimotor communication was reduced in a fourth experiment where co‐actors could communicate with weight‐related symbols. Our findings demonstrate that the use of sensorimotor communication extends beyond the communication of spatial locations to non‐spatial, hidden object properties. (shrink)

The idea of complementarity is one of the key concepts of quantum mechanics. Yet, the idea was originally developed in William James’ psychology of consciousness. Recently, it was re-applied to the humanities and forms one of the pillars of modern quantum cognition. I will explain two different concepts of complementarity: Niels Bohr’s ontic conception and Werner Heisenberg’s epistemic conception. Furthermore, I will give an independent motivation of the epistemic conception based on the so-called operational interpretation of quantum theory, which has (...) powerfully been applied in the domain of quantum cognition. Finally, I will give examples illustrating the potency of complementarity in the domains of bounded rationality and survey research. Concerning the broad topic of consciousness, I will focus on the psychological aspects of awareness. This closes the circle spanning complementarity, quantum cognition, the operational interpretation, and consciousness. (shrink)

The present volume is devoted to the theme of Divine Father in Second Temple Jewish and early Christian tradition and in its ancient pagan contexts. It brings together proceedings of a conference under the same title, held in Gottingen in September 2011. Selected articles by well-known scholars focus on religious and philosophical concepts of divine parenthood in antiquity, from the Hebrew Bible and Second Temple Judaism (the Dead Sea Scrolls, Targums, Philo and Josephus) to the field of the New Testament. (...) In addition, the volume deals with the designation of deity as father or mother from the broad spectrum of ancient Egypt and classical antiquity (Homer, Hesiod, Plato, and its reception) to late antiquity (Plotinus and Porphyry).".

At one time, specialized health privacy laws represented the bulk of the rules regulating genetic privacy, Today, however, as both the field of genomics and the content of privacy law change rapidly, a new generation of general-purpose privacy laws may impose new restrictions on collection, storage, and disclosure of genetic data. This article surveys these laws and considers implications.

There is a gap between two different modes of computation: the symbolic mode and the subsymbolic (neuron-like) mode. The aim of this paper is to overcome this gap by viewing symbolism as a high-level description of the properties of (a class of) neural networks. Combining methods of algebraic semantics and non-monotonic logic, the possibility of integrating both modes of viewing cognition is demonstrated. The main results are (a) that certain activities of connectionist networks can be interpreted as non-monotonic inferences, and (...) (b) that there is a strict correspondence between the coding of knowledge in Hopfield networks and the knowledge representation in weight-annotated Poole systems. These results show the usefulness of non-monotonic logic as a descriptive and analytic tool for analyzing emerging properties of connectionist networks. Assuming an exponential development of the weight function, the present account relates to optimality theory – a general framework that aims to integrate insights from symbolism and connectionism. The paper concludes with some speculations about extending the present ideas. (shrink)
