text: 'It has been proposed that the design of robots might benefit from interactions
that are similar to caregiver–child interactions, which is tailored to children’s
respective capacities to a high degree. However, so far little is known about
how people adapt their tutoring behaviour to robots and whether robots can evoke
input that is similar to child-directed interaction. The paper presents detailed
analyses of speakers’ linguistic and non-linguistic behaviour, such as action
demonstration, in two comparable situations: In one experiment, parents described
and explained to their nonverbal infants the use of certain everyday objects;
in the other experiment, participants tutored a simulated robot on the same objects.
The results, which show considerable differences between the two situations on
almost all measures, are discussed in the light of the computer-as-social-actor
paradigm and the register hypothesis.'

text: Given a field extension K/k of degree n we are interested in finding the subfields
of K containing k. There can be more than polynomially many subfields. We introduce
the notion of generating subfields, a set of up to n subfields whose intersections
give the rest. We provide an efficient algorithm which uses linear algebra in
k or lattice reduction along with factorization in any extension of K. Implementations
show that previously difficult cases can now be handled.

text: 'This article analyses 336 German venture capital transactions from 1990 to
2005 and seeks to determine why selected financial securities differ across deals.
We find that a broad array of financial instruments is used, covering straight
equity, mezzanine and debt‐like securities. Based on the chosen financial securities’
upside potential and downside protection characteristics, we provide an explanation
for the differing use of these securities. Our results show that investors’ deal
experience, adverse selection risks and economic prospects in the public equity
market influence the selection of financial securities. '

text: '"Lernkultur" wird als Begriff häufig gebraucht und fast ebenso häufig definiert
das gilt für den betrieblichen Kontext ebenso wie für die Bereiche der Schul-,
Hochschul-, Berufs- und Erwachsenenbildung (z. B. Wulf, Althans, Blaschke, Ferrin,
Göhlich, Jörissen, Mattig et al., 2007; Jenert, Zellweger Moser, Dommen & Gebhardt,
2009; Kirchhöfer, 2004; Erpenbeck & Sauer, 2000). Trotz der grossen Aufmerksamkeit,
die der Begriff in den letzten zwei Jahrzehnten erfahren hat, kann man nicht von
einem in sich geschlossenen Forschungsprogramm sprechen. Die Zugänge zum Phänomenbereich
Lernkultur sind ebenso vielfältig wie die hinter einzelnen Ansätzen stehenden
Lernkulturkonstrukte. Den Autoren ist keine Publikation bekannt, welche unterschiedliche
Ansätze der Lernkulturforschung systematisch aufarbeitet. Eine wichtige Referenzquelle
ist der Bericht von Kuh und Whitt (1988) "The Invisible Tapestry: Culture in American
Colleges and Universities". Ausgehend von einer fundierten Übersicht zu unterschiedlichen
Zugängen zum Kulturbegriff (oft in starker Anlehnung an die Organisationskulturforschung
(vgl. Allaire & Firsirotu, 1984)) stellen die Autoren ein Rahmenmodell zur Analyse
von Hochschulkulturen vor (Kuh und Whitt, 1988, S. 56). Diese Arbeit erweist sich
für ein besseres Verständnis unter-schiedlicher Zugänge zum Lernkulturbegriff
als aufschlussreich, weil im Kontext Hoch-schule zwangsweise viele Aspekte des
Lernens und Lehrens angesprochen werden. Allerdings fokussiert auch dieser Bericht
nicht das Konstrukt der Lernkultur und bietet damit nur einen Ausgangspunkt für
die Identifizierung unterschiedlicher Zugänge.'

text: Recent advances in information processing enable new kinds of technical systems,
called self-optimizing systems. These systems are able to adapt their objectives
and their behavior according to the current situation and influences autonomously.
This behavior adaptation is non-deterministic and hence self-optimization is a
risk to the system, e.g. if the result of the self-optimization process does not
match the suddenly changed situation. In contrary, self-optimization could be
used to increase the dependability by pursuing objectives like reliability and
availability. In our preceding publications we introduced the so called multi-level
dependability concept to cope with this new kind of systems (cf. [6]). This concept
comprises the monitoring of the system behavior, the classification of the current
situation, and the selection of the appropriate measure, if reliability limits
are exceeded. In this paper we present for the first time experimental results.
The dependability concept is implemented in the self-optimizing active guidance
system of a railway vehicle. The test drives illustrate clearly that the proposed
concept is able to cope with, e.g., sensor failures, and is able to increase the
reliability and availability of the active guidance module.

text: 'Enduring doubts about the value of IS investments reveal that IS researchers
have not fully managed to identify and to explain the economic benefits of IS.
Three research tasks are essential requisites on the path towards addressing this
criticism: the synthesis of knowledge, the identification of lack of knowledge,
and the proposition of paths for closing knowledge gaps. This paper considers
each of these tasks by a) synthesizing key research findings based on a comprehensive
literature review, b) identifying and unfolding key limitations of current research,
and c) applying a decision-theoretic perspective, which opens new horizons to
IS business value research and shows paths for overcoming the limitations. The
adoption of this perspective results in a decision-theoretic foundation of IS
business value research and includes the proposition of a consistent terminology
and a research model that frames further research.'

text: Enduring doubts about the value of IS investments reveal that IS researchers
have not fully managed to identify and to explain the economic benefits of IS.
This paper assumes that literature reviews, which represent a powerful instrument
for the identification and synthesis of knowledge, have not tapped their full
potential to address this issue due to deficiencies in methodology. The analysis
of 18 literature reviews published in pertinent academic outlets during the past
20 years shows such deficiencies. Two of the most critical weaknesses identified
are (1) the lack of theory use in most reviews and (2) a weak linkage of reviews,
resulting in little progress in theory and framework development. The systematic
identification of these weaknesses and the extraction of promising methodological
examples from past literature are the main contributions of this work, which supports
the composition of more effective literature reviews in future research.

text: "Im vorliegenden Beitrag wird der Zusammenhang zwischen der Fähigkeit zur
Perspektivenübernahme und sinnverstehendem Lesen dargestellt. Auf der Grundlage
von Arbeiten zum Textverstehen sowie zu Perspektivenübernahme und Theory of Mind
wurde ein positiver Zusammenhang zwischen Perspektivenübernahmefähigkeit und Textverstehensleistung
erwartet. Diese Hypothese wurde an zwei Stichproben unterschiedlichen Alters geprüft:
In der ersten Studie beantworteten 37 Vorschulkinder Fragen zu vorgelesenen Geschichten
sowie Perspektivenübernahme-Aufgaben. Zwischen den Bereichen fand sich eine deutliche
positive Korrelation, die bei\r\nKontrolle der Intelligenz erhalten blieb. An
der zweiten Studie nahmen 69 Grundschulkinder der\r\ndritten Jahrgangsstufe teil,
die Texte lasen und Aufgaben dazu wie auch zur Perspektivenübernahme bearbeiteten.
In dieser Stichprobe fand sich der erwartete Zusammenhang ausschließlich\r\nin
der Teilgruppe der guten Leser. Er blieb bei Kontrolle der Intelligenz erhalten.
Die Ergebnisse\r\nwerden auch in Hinblick auf die Förderung der Lesekompetenz
diskutiert."

text: A simple pre-stress estimate method of Langevin transducers is studied. The
measurement setup consists of a capacitor, an impedance converter and a voltmeter.
Based on the piezoelectric equation and the basic circuit theory, the mathematical
expression between the pre-stress and the voltage across the capacitor is derived.
The pre-stress level can then be calculated out of the measurement of the capacitor
voltage. In order to evaluate the precision of this method, a force washer is
used to measure the pre-stress of the Langevin transducer. The result shows the
pre-stress level obtained from this method is 30-40\% higher than the pre-stress
level measured by the force washer. This method is simple and can be used to estimate
the pre-stress of various Langevin transducers. The precision of this method can
be raised if d33 is identified under different pre-stress levels.

text: "Der Beitrag beschreibt die Potenziale informeller Mitarbeiter-Communities
für die Innovationsfähigkeit kleiner und mittlerer Unternehmen (KMU). Innovationsmanagement\r\nbezieht
sich in der Regel auf grosse Unternehmen. Die speziellen Bedürfnisse und Möglichkeiten
von KMU werden dabei oftmals vernachlässigt. Auf Basis einer Fallstudie werden
daher Gestaltungsmöglichkeiten für innovationsfreundliche\r\nArbeitskontexte in
kleinen und mittleren Betrieben herausgearbeitet. Im Mittelpunkt der Analyse stehen
Kriterien, die kritisch für die Entstehung und den Fortbestand informeller Innovationsnetzwerke
innerhalb formeller Organisationsstrukturen sind. Die Studie greift auf Erkenntnisse
der Kreativitäts- und der Lernforschung zurück\r\nund bezieht sich explizit auf
den Community of Practice-Ansatz. Abschliessend werden die Grenzen eines \"Managements\"
innovativer\r\nMitarbeiternetzwerke diskutiert und Möglichkeiten der Gestaltung
von Arbeitskontexten vorgestellt."

text: 'We study the asymptotics conjecture of Malle for dihedral groups Dℓ of order
2ℓ, where ℓ is an odd prime. We prove the expected lower bound for those groups.
For the upper bounds we show that there is a connection to class groups of quadratic
number fields. The asymptotic behavior of those class groups is predicted by the
Cohen--Lenstra heuristics. Under the assumption of this heuristic we are able
to prove the expected upper bounds. '

text: The paper is concerned with binaural signal processing for a bimodal human-robot
interface with hearing and vision. The two microphone signals are processed to
obtain an enhanced single-channel input signal for the subsequent speech recognizer
and to localize the acoustic source, an important information for establishing
a natural human-robot communication. We utilize a robust adaptive algorithm for
filter-and-sum beamforming (FSB) and extract speaker direction information from
the resulting FIR filter coefficients. Further, particle filtering is applied
which conducts a nonlinear Bayesian tracking of speaker movement. Good location
accuracy can be achieved even in highly reverberant environments. The results
obtained outperform the conventional generalized cross correlation (GCC) method.
