Cognitive functions like perception, memory, language, or consciousness are based on highly parallel and distributed information processing by the brain. One of the major unresolved questions is how information can be integrated and how coherent representational states can be established in the distributed neuronal systems subserving these functions. It has been suggested that this so-called ''binding problem'' may be solved in the temporal domain. The hypothesis is that synchronization of neuronal discharges can serve for the integration of distributed neurons into (...) cell assemblies and that this process may underlie the selection of perceptually and behaviorally relevant information. As we intend to show here, this temporal binding hypothesis has implications for the search of the neural correlate of consciousness. We review experimental results, mainly obtained in the visual system, which support the notion of temporal binding. In particular, we discuss recent experiments on the neural mechanisms of binocular rivalry which suggest that appropriate synchronization among cortical neurons may be one of the necessary conditions for the buildup of perceptual states and awareness of sensory stimuli.

Mit P. Bernays geht S. Körner in der Nachfolge von I . Kant und J.F. Fries davon aus, "daß eine gewisse Art rein-anschaulicher Erkenntnis als Ausgangspunkt der Mathematik genommen werden muß." Andererseits betont Körner einen Wechsel z.B. der geometrischen Anschauung in den nicht-euklidischen Geometrien, der durch die Unabhängigkeitsbeweise für geometrische Axiome (z.B. Parallelenaxiom) möglich wurde. Analog könnte man von einem Wechsel der mengentheoretischen Anschauung in nicht-cantorschen Mengenlehren sprechen, der durch Unabhängigkeitsbeweise mengentheoretischer Axiome (z.B. Auswahlaxiom, Kontinuumshypothese) eingeleitet wurde. In der (...) Algebra werden Axiomensysteme untersucht, in denen nicht mehr alle anschaulichen Rechengesetze der (reellen) Zahlen (z.B. Kommutativgesetz bei Quaternionen, Assoziativgesetz bei Oktaven) gelten. Für die Analysis lassen sich nonstandard Modelle (A. Robinson) angeben. Angesichts dieses Pluralismus der Modelle und Axiomensysteme kann man nicht mehr von der einen anschaulichen Mathematik sprechen — wie in den Tagen von Euklid, Piaton, Leibniz und Kant. Es stellt sich daher die Aufgabe einer Erkenntnistheorie der Mathematik, deren Kategorien den modernen Problementwicklungen Rechnung tragen, aber auch ihre anschaulich-konstruktiven Grundlagen aufzeigen.

A profoundly heartening view of human nature, Beyond War offers a hopeful prognosis for a future without war. Douglas P. Fry convincingly argues that our ancient ancestors were not innately warlike--and neither are we. He points out that, for perhaps ninety-nine percent of our history, for well over a million years, humans lived in nomadic hunter-and-gatherer groups, egalitarian bands where warfare was a rarity. Drawing on archaeology and fascinating recent fieldwork on hunter-gatherer bands from around the world, Fry debunks the (...) idea that war is ancient and inevitable. For instance, among Aboriginal Australians, warfare was an extreme anomaly. Fry also points out that even today, when war seems ever present, the vast majority of us live peaceful, nonviolent lives. We are not as warlike as we think, and if we can learn from our ancestors, we may be able to move beyond war to provide real justice and security for the world. (shrink)
Various explanations are offered to explain why employees increasingly work longer hours: the combined effects of technology and globalization; people are caught up in consumerism; and the "ideal worker norm," when professionals expect themselves and others to work longer hours. In this article, we propose that the processes of employer recruitment and selection, employee self-selection, cultural socialization, and reward systems help create extended work hours cultures (EWHC) that reinforce these trends. Moreover, we argue that EWHC organizations are becoming more prevalent (...) and that organizations in which long hours have become the norm may recruit for and reinforce workaholic tendencies. Next, we offer spiritual leadership as a paradigm for organizational transformation and recovery from the negative aspects of EWHC to enhance employee wellbeing and corporate social responsibility without sacrificing profitability, revenue growth, and other indicators of financial performance. Finally, we will offer suggestions for future theory, research, and practice. (shrink)
In this paper I explore the nature, varieties, causes and meanings of comebacks related to sport. I argue that comebacks have an axiological dimension, and that the best comebacks involve personal growth. I attempt to show that a major reason that comebacks connected to sport are often inspiring is that we are all in need of a comeback at some point in our lives. When improbable comebacks occur in the world of sport, they expand our sense of possibility.

This paper explores whether resolving to "live like there's no tomorrow" would be conducive to living life to the fullest. While there is much to commend a life lived with a sense of urgency, I conclude that living like there's no tomorrow, in the final analysis, is neither advisable, nor realizable. In its place I suggest a life lived in mindfulness of the transitory and uncertain nature of our lives.
Drawing upon two independent national samples of 201 and 241 psychology graduate students, this article describes the development and psychometric evaluation of 4 Web-based student self-report scales tapping student socialization in the responsible conduct of research (RCR) with human participants. The Mentoring the Responsible Conduct of Research Scale (MRCR) is composed of 2 subscales assessing RCR instruction and modeling by research mentors. The 2 subscales of the RCR Department Climate Scale (RCR-DC) assess RCR department policies and faculty and student RCR (...) practices. The RCR Preparedness scale (RCR-P) and the RCR Field Integrity scale (RCR-FI) measure respectively students' confidence in their ability to conduct research responsibly and their belief in the RCR integrity of psychology as a discipline. Factor analysis, coefficient alphas, correlations, and multiple regression analyses demonstrated each of the scales had good internal consistency and concurrent and construct validity. (shrink)
