Changes in mean fundamental frequency accompanying changes in loudness of phonation are analyzed in 9 professional singers, 9 nonsingers, and 10 male and 10 female patients suffering from vocal functional dysfunction. The subjects read discursive texts with noise in earphones, and some also at voluntarily varied vocal loudness. The healthy subjects phonated as softly and as loudly as possible at various fundamental frequencies throughout their pitch ranges, and the resulting mean phonetograms are compared. Mean pitch was found to increase by about half-semitones per decibel sound level. Grossly, the subject groups gave similar results, although the singers changed voice pitch more than the nonsingers. The voice pitch changes may be explained as passive results of changes of subglottal pressure required for the sound level variation. 相似文献

A quaternionic projective theory based on the symmetry group Sl(2,H) allows one to identify various hadron models and many well-known particle transformation laws in its subgroup chains. Identifying the 16-dimensional Dirac algebra {} with Sl(2,H), we use a well-established group-theoretic framework as well as the framework of projective geometry to classify elementary particles and describe their interactions at low energies. It is straightforward to derive Chiral Dynamics and explain the spinorial ('quark') structure of hadrons. Spontaneous symmetry breaking occurs naturally by coset reductions, whereas 'classical' physics is obtained via well-defined limits in terms of a group contraction. The Dirac equation can be identified within a Riemannian globally symmetric space and thus allows one to investigate the fermionic mass as a well-defined parameter. In addition, we suggest an identification of the second quantization scheme and an approach to sum up the perturbation series. 相似文献

This contribution investigates the function of emotion in relation to norms, both in natural and artificial societies. We
illustrate that unintentional behavior can be normative and socially functional at the same time, thereby highlighting the
role of emotion. Conceiving of norms as mental objects we then examine the role of emotion in maintaining and enforcing such
propositional attitudes. The findings are subsequently related to social structural dynamics and questions concerning micro-macro
linkage, in natural societies as well as in artificial systems. Finally, we outline the possibilities of an application to
the socionic multi-agent architecture SONAR.
Christian von Scheve graduated in Sociology with minors in Psychology, Economics, and Political Science at the University of Hamburg, where he
also worked as a research assistant at the Institute of Sociology. Currently, he is a 3rd year PhD student at the University
of Hamburg. He was a Fellow of the Research Group “Emotions as Bio-Cultural Processes” at the Center for Interdisciplinary
Research (ZiF) at Bielefeld University. In his doctoral thesis he develops an interdisciplinary approach to emotion and social
structural dynamics, integrating emotion theories from the neurosciences, psychology, and the social sciences. He has published
on the role of emotion in large-scale social systems, human-computer interaction, and multi-agent systems. He is co-editor
of a forthcoming volume on emotion regulation.
Daniel Moldt received his BSc in Computer Science/Software Engineering from the University of Birmingham (England) in 1984, graduated
in Informatics at the University of Hamburg, with a minor in Economics in 1990. He received his PhD in Informatics from the
University of Hamburg in 1996, where he has been a researcher and lecturer at the Department of Informatics since 1990. Daniel
Moldt is also the head of the Laboratory for Agent-Oriented Systems (LAOS) of the theoretical foundations group at the Department
of Informatics. His research interests focus on theoretical foundations, software engineering and distributed systems with
an emphasis on agent technology, Petri nets, specification languages, intra- and inter-organizational application development,
Socionics and emotion in informatics.
Julia Fix is currently a PhD student at the Theoretical Foundations of Computer Science Group, Department for Informatics at the University
of Hamburg. She studied Informatics and Psychology at the University of Hamburg, with an emphasis on theoretical foundations
of multi-agent systems and wrote her diploma theses about emotional agent systems. Her current research interests focus on
conceptual challenges and theoretical foundations of modelling emotions in multi-agent systems, emotion-based norm enforcement
and maintenance, and Socionics. A further research focus are Petri nets, in particular the use of Petri-net modelling formalisms
for representing different aspects of emotion in agent systems.
Rolf von Lüde is a professor of Sociology at the University of Hamburg with a focus in teaching and research in Sociology of Organizations,
Work and Industry since 1996. He graduated in Economics, Sociology, and Psychology, and received his doctorate in Economics
and the venia legendi in Sociology from the University of Dortmund. His current research focuses on labor conditions, the
organization of production, social change and the educational system, the organizational structures of university, Socionics
as a new approach to distributed artificial intelligence in cooperation with computer scientists, new public management, and
emotions and social structures. Rolf von Lüde is currently Head of Department of Social Sciences and Vice Dean of the School
of Business, Economics and Social Sciences, University of Hamburg. 相似文献
