Collective Decision Making as the Actualization of Decision Potential
This paper presents some characteristics and dilemmas of collective decision making. Collective decision making could be presented as the process of successive crystallization of dominant alternatives under the influence of different decision contexts from primary given decision potentials. This process is presented as the many-phased process of the acting of contextually dependent "energizing factors" of the collective decision making on the "attractiveness matrix" of outcomes of collective decisions. The attractiveness matrix determines the attractiveness for each alternative of decision, and the most attractive alternative in the given situation presents the rational decision in the given situation. In the final phase of decision making holds a context which gets a simplified attractiveness matrix. It corresponds to the common decision for one of the alternatives.collective decision making, rationality, decision potential, joint outcomes, energizing
From phrase structure to dependencies, and back
Transforming constituent-based annotation into dependency-based annotation has been shown to work for different treebanks and annotation schemes (e.g. Lin (1995) has transformed the Penn treebank, and Kübler and Telljohann (2002) the Tübinger Baumbank des Deutschen (TüBa-D/Z)). These ventures are usually triggered by the conflict between theory-neutral annotation, that targets most needs of a wider audience, and theory-specific annotation, that provides more fine-grained information for a smaller audience. As a compromise, it has been pointed out that treebanks can be designed to support more than one theory from the start (Nivre, 2003). We argue that information can also be added to an existing annotation scheme so that it supports additional theory-specific annotations. We also argue that such a transformation is useful for improving and extending the original annotation scheme with respect to both ambiguous annotation and annotation errors. We show this by analysing problems that arise when generating dependency information from the constituent-based TüBa-D/Z
In Search of Stars: Network Formation among Heterogeneous Agents
This paper reports the results of a laboratory experiments on network formation among heterogeneous agents. The experimental design extends the basic Bala-Goyal (2000) model of network formation with decay and two-way flow of benefits by allowing for agents with lower linking costs or higher benefits to others. We consider treatments where agents’ types are common knowledge and treatments where agents’ types are private information. In all treatments, the (efficient) equilibrium network has a “star” structure. We find that with homogeneous agents, equilibrium predictions fail completely. In Contrast, with heterogeneous agents stars frequently occur, often with the high-value or low- cost agent in the center. Stars are not borne but rather develop: in treatments with a high-value agents, the network’s centrality, stability, and efficiency all increase over time. Our results suggest that agents’ heterogeneity is a major determinant for the predominance of star-like structures in real-life social networks.microeconomics ;
A hybrid architecture for robust parsing of german
This paper provides an overview of current research on a hybrid and robust parsing architecture for the morphological, syntactic and semantic annotation of German text corpora. The novel contribution of this research lies not in the individual parsing modules, each of which relies on state-of-the-art algorithms and techniques. Rather what is new about the present approach is the combination of these modules into a single architecture. This combination provides a means to significantly optimize the performance of each component, resulting in an increased accuracy of annotation
Democracy and Regulation: The Effects of Electoral Competition on Infrastructure Investments
This paper investigates infrastructure investment in markets where regulation is subject to varying degrees of manipulation by elected politicians. Based on a model of price regulation in a market with increasing demand and long-term returns on investment we construct a multi-period game between a service provider, consumers with voting rights and elected decision makers. In each period the consumers elect a decision maker who may then regulate the price for service provision. Before an election the service provider chooses whether to increase its capacity. Investment is irreversible and profitable only with a sufficiently high price. We derive the subgame perfect equilibrium for this game and investigate the price and investment dynamics through an experiment with human subjects. The experimental results show that service providers invest when decision-makers' interests align with their own, though prices may rise inefficiently high when the regulatory framework is made independent of future political manipulation. Independency of regulation thus decreases efficiency and consumer surplus. In contrast, when decision-makers' interests do not align with service providers' we find efficiency only when regulation can be made independent from electoral dynamics
Kann etwas Rotes zugleich grün sein?
Ich analysiere die "syntaktische" Lösung Wittgensteins der\ud
apriorischen Farbensätze aus den späten zwanziger und\ud
dreißiger Jahren. Wittgenstein versuchte, den Farbensatz\ud
"Etwas kann nicht zugleich Grün und Rot sein" als einen\ud
Scheinsatz darzustellen, der eine bestimmte syntaktische\ud
Unmöglichkeit ausdrückt, doch dieser Versuch ist nicht\ud
gelungen, denn man muß die apriorische Wahrheit des\ud
Farbensatzes dabei schon in irgendeiner Weise voraussetzen.\ud
Auch die Kritik Wittgensteins an der Deutung der\ud
Farbensätze bei Husserl stimmt nicht, denn Wittgenstein\ud
hat darin die logische und die apriorische (Un)möglichkeit\ud
der Farbenunterschiede gleichgesetzt. Viele andere Versuche\ud
der "analytischen" Deutung dieses Satzes sind\ud
ebenso mißglückt
On the Distribution of Calls in a Wireless Network driven by Fluid Traffic
This note develops a modelling approach for wireless networks driven byfluid traffic models. Introducing traffic sets that follow movement ofsubscribers, the wireless network with time-varying rates is transformedinto a stationary network at these traffic sets, which yields that thedistribution of calls over the cells of the network depends on the calllength distribution only through its mean. The result is extended to anetwork of infinite server queues with time-varying arrival rates
Orbital Dependent Exchange-Only Methods for Periodic Systems
Various orbital-dependent exchange-only potentials are studied which exhibit
correct long-range asymptotic behaviour. We present the first application of
these potentials for polymers and by one of these potentials for molecules.
Kohn-Sham type calculations have been carried out for polyethylene in order to
make valuable comparison of these potentials with each other as well as with
Hartree-Fock and exchange-only LDA methods. The Kohn-Sham band gap obtained
with the optimized effective potetial method is corrected with the exchange
contribution to the derivative discontinuity of the exchange-correlation
potential. The corrected band gap obtained with the Slater's exchange potential
is 9.7 eV close to the experiment.Comment: 11 pages, 2 figures. Phys. Rev. B60, 1999, in pres
In Search of Stars: Network Formation among Heterogeneous Agents
This paper reports results from a laboratory experiment on network formation among heterogeneous agents. The experimental design extends the Bala-Goyal (2000) model of network formation with decay and two-way flow of benefits by allowing for agents with lower linking costs or higher benefits to others. Furthermore, agents’ types may be common knowledge or private information. In all treatments, the (efficient) equilibrium network has a “star” structure. With homogeneous agents, equilibrium predictions fail completely. In contrast, with heterogeneous agents stars frequently occur, often with the high-value or low-cost agent in the center. Stars are not born but rather develop: with a high-value agent, the network’s centrality, stability, and efficiency all increase over time. Probit estimations based on best-response behaviour and other-regarding preferences are used to analyze individual linking behavior. Our results suggest that heterogeneity is a major determinant for the predominance of star-like structures in real-life social networks.Network Formation, Experiment, Heterogeneity, Private Information
