    Description / Table of Contents: Zusammenfassung Ein Modell für Mehrpersonen-Mehrkriterien-Entscheidungsprobleme wird vorgeschlagen, indem jedes Individuum charakterisiert wird von einem Gewicht und gleichzeitig von einem Kriterien-Vektor. Eine Familie von Lösungen, parameterisiert von einem Parameter, wird entwickelt, wobei bestimmte Lösungen in dieser Familie bestimmten statistischen Konzepten entprechen. Unser Ansatz weist Parallelen mit dem Ansatz der Potentialfunktion in der Physik auf.
    Notes: Summary A model for multiperson multicriteria decision making is proposed, in which each individual is characterized by a weight together with a vector expressing that individual's position or preferences with respect to a number of criteria. Next, a one-parameter class of solutions is developed, of which specific members bear a strong resemblance to concepts from statistics. Our approach is related to the potential function approach in physics.

    Seasonality of circadian locomotor activity in an insect (1993)
    Springer
    Journal of comparative physiology 171 (1993), S. 713-724 
    Details
    ISSN: 1432-1351
    Keywords: Circadian rhythms ; Seasonality ; Locomotor activity ; Carabid beetles
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine
    Notes: Abstract Daily periodic locomotor activity of Carabus auronitens was recorded in a climate-constant laboratory with the animals exposed to naturally changing photoperiods. Most actograms exhibit directed seasonal variations of duration and phase position of daily activity. Seasonal locomotor activity starts in early spring (following dormancy) on a low daily level, first being confined to a short time span around dusk (and even shorter around dawn). In the course of season, the daily onsets of activity become closely related with sunset and the duration of daily activity is steadily extended with both parts of the bimodal phase fusing to a common, unimodal activity band by late spring. Subsequently, it is further extended into forenoon, until in summer (shortly before aestivation), spontaneous phase inversion turns activity periodicity from nocturnality into diurnality within 1 day. Such seasonal variations are paralleled by changes in the precision of synchronization of the individuals' activity rhythms to the entraining light/dark cycle. No geographical differences were detected. The results support the idea of the circadian clock as a system of two dynamically coupled physiological oscillators that invert their phase relation as soon as the natural dark phase falls short of some minimum-tolerable night length.

    Feeding effects on daily locomotor activity in Carabus auronitens (1993)
    Springer
    Journal of comparative physiology 173 (1993), S. 49-55 
    Details
    ISSN: 1432-1351
    Keywords: Circadian rhythms ; Feeding effects ; Locomotor activity ; Ground beetles
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine
    Notes: Abstract Effects of food supply on daily periodic locomotor activity in the ground beetle Carabus auronitens were recorded in the laboratory with the animals exposed to natural daylight and photoperiod. Inspection of individual actograms exhibits that in most cases feeding leads to strongly reduced and more or less irregularly distributed activity for a period of up to 4 days. In terms of quantitative parameters, the animals respond to food supply by an immediate reduction of mean amounts of daily activity. This is achieved through the reduction of duration (as a consequence of reduced burstlengths instead of burstnumber) and, less distinctly, the reduction of intensity. The initial levels of parameters are reattained after 4 days. Direct comparison by means of standardized (i.e. level-independent) relative parameter functions demonstrates close concordance between the amount and duration of daily activity; however, distinct synchronous change of intensity is apparent as a consequence of food supply only. This means that any variation of activity amounts is due to changing duration rather than to intensity variation. In analogy to the feeding-dependent parameter dynamics, also the proportion of animals with strong synchronization to the natural light/dark cycle is considerably reduced by food supply. The feeding-dependent reduction of activity is paralleled by temporarily reduced activity of proteolytic enzymes in the beetles. It is argued that, for the purpose of energy saving, the animals will remain inactive as long as reduced enzyme activity inhibits further consumption and digestion of food.

    Pareto optimality, anonymity, and strategy-proofness in location problems (1992)
    Springer
    International journal of game theory 21 (1992), S. 221-235 
    Details
    ISSN: 1432-1270
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mathematics , Economics
    Notes: Abstract Generalized location problems withn agents are considered, who each report a point inm-dimensional Euclidean space. A solution assigns a compromise point to thesen points, and the individual utilities for this compromise point are equal to the negatives of the Euclidean distances to the individual positions. Form = 2 andn odd, it is shown that a solution is Pareto optimal, anonymous, and strategy-proof if, and only if, it is obtained by taking the coordinatewise median with respect to a pair of orthogonal axes. Further, for all other situations withm≥2, such a solution does not exist. A few results concerning other solution properties, as well as different utility functions, are discussed.

    Structuring scientific activities by co-author analysis (1991)
    Springer
    Scientometrics 20 (1991), S. 235-255

    ISSN: 1588-2861
    Source: Springer Online Journal Archives 1860-2000
    Topics: Information Science and Librarianship , Nature of Science, Research, Systems of Higher Education, Museum Science
    Notes: Abstract In this paper we apply ‘co-author analysis’ to create from a large set of publications clusters of collaborating researchers within a faculty of chemical engineering. Results have been discussed with an expert. The co-author clusters appeared to be meaningful, with respect to the identification of research groups, the relations within these groups, as well as to relations between these groups and changes in time. Also differences between ISI-based and non-ISI based maps proved to be consistent with the expert's opinion. Many clusters represent collaborating authors grouped around a full professor, mostly the department chairman. Co-author analysis can be used, for example, as an important tool in evaluative bibliometrics in order to make a first identification of research groups in ‘unknown’ universities or organizations.

    A bibliometric profile of top-scientists a case study in chemical engineering (1994)

    Notes: Abstract We carefully selected a group of chemical engineering scientists internationally recognized as ‘top-scientists’ in their field. A method has been developed to systematically compare bibliometric characteristics of these top-scientists with an ’average scientist‘ in chemical engineering. This method also includes citation-analysis of books and proceedings. The results show a very clear ‘bibliometric profile’. First, top-scientists’ references are more numerous and, fourth, they concern more recent literature. Our fifth findings is that the journals used by top-scientists for their publications are representative for the field of chemical engineering as a whole. But they differ in specific aspects significantly from the ‘average’ journal structure in chemical engineering: the published work of top-scientists is both ‘general’ as well as more specialistic than the average work in chemical engineering.

    Nash refinement of equilibria (1994)
    Springer
    Journal of optimization theory and applications 83 (1994), S. 355-373

    ISSN: 1573-2878
    Keywords: Noncooperative games ; Nash equilibrium ; Nash bargaining solution ; refinements
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mathematics
    Notes: Abstract A method for choosing equilibria in strategic form games is proposed and axiomatically characterized. The method as well as the axioms are inspired by the Nash bargaining theory. The method can be applied to existing refinements of Nash equilibrium (e.g., perfect equilibrium) and also to other equilibrium concepts, like correlated equilibrium.
