Giga-Hertz-Preis | 2008
No full textZum zweiten Mal verleiht das ZKM | Zentrum für Kunst und Medientechnologie gemeinsam mit dem EXPERIMENTALSTUDIO des SWR den Giga-Hertz-Preis für elektronische Musik. Der Giga-Hertz-Preis ist der weltweit höchstdotierte Preis für elektronische Musik mit einem Hauptpreis für das Lebenswerk eines Komponisten von € 15.000 und vier Produktionspreisen zu je € 8.000. Die Jury 2008 besteht aus den künstlerischen Leitern der beteiligten Studios Ludger Brümmer (ZKM | Institut für Musik und Akustik), Detlef Heusinger (Experimentalstudio des SWR) sowie François Bayle (Pionier der elektroakustischen und akusmatischen Musik und Entwickler des Akusmoniums), Jonathan Harvey (Komponist, erhielt 2007 den erstmals verliehenen Giga-Hertz-Hauptpreis in Anerkennung für sein Lebenswerk), Armin Köhler (Redaktionsleiter für Neue Musik beim SWR und verantwortlich für die Donaueschinger Musiktage) sowie Peter Weibel (Vorstand des ZKM | Karlsruhe, ehemaliger Leiter der Ars Electronica in Linz). Schirmherr des Giga-Hertz-Preises 2008 ist Günther H. Oettinger (Ministerpräsident des Landes Baden-Württemberg)

Characterizing the time-perspective of nations with search engine query data
No full textVast quantities of data on human behavior are being created by our everyday internet usage. Building upon a recent study by Preis, Moat, Stanley, and Bishop (2012), we used search engine query data to construct measures of the time-perspective of nations, and tested these measures against per-capita gross domestic product (GDP). The results indicate that nations with higher per-capita GDP are more focused on the future and less on the past, and that when these nations do focus on the past, it is more likely to be the distant past. These results demonstrate the viability of using nation-level data to build psychological constructs
Control and Filtering for Discrete Linear Repetitive Processes with H infty and ell 2--ell infty Performance
No full textRepetitive processes are characterized by a series of sweeps, termed passes, through a set of dynamics defined over a finite duration known as the pass length. On each pass an output, termed the pass profile, is produced which acts as a forcing function on, and hence contributes to, the dynamics of the next pass profile. This can lead to oscillations which increase in amplitude in the pass to pass direction and cannot be controlled by standard control laws. Here we give new results on the design of physically based control laws for the sub-class of so-called discrete linear repetitive processes which arise in applications areas such as iterative learning control. The main contribution is to show how control law design can be undertaken within the framework of a general robust filtering problem with guaranteed levels of performance. In particular, we develop algorithms for the design of an H? and dynamic output feedback controller and filter which guarantees that the resulting controlled (filtering error) process, respectively, is stable along the pass and has prescribed disturbance attenuation performance as measured by and – norms
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Preis- und Erlösstrategien auf elektronischen Märkten
No full textDurch das Internet entstehen neue Formen des elektronischen Geschäftsverkehrs (E-Commerce). Die elektronischen Märkte nähern sich dabei immer mehr dem aus der klassischen Volkswirtschaftslehre bekannten Ideal des "vollkommenen Gütermarktes". Gleichzeitig lassen sich neue Preis- und Erlösstrategien beobachten, die auf den besonderen Eigenschaften der elektronischen Märkte basieren. Wie ist diese Entwicklung aus mikroökonomischer Sicht zu bewerten
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
