text: 'Research on teaching and learning in higher education has first and foremost
centered on individuals, i.e. students'' and teachers'' approaches to learning
and teaching as well as methods (Entwistle, McCune, & Scheja, 2006; Entwistle
& Peterson, 2004). As a consequence, concepts on how to improve and innovate education
at higher education institutions (HEI) have stayed on the level of individual
courses, trying to qualify teachers to implement new teaching and learning methods
in their classrooms (Aineley, 2008, S. 619). Yet, there are both theoretical as
well as practical reasons that argue for a broader perspective on learning processes
and, as a consequence, reach beyond the course-level but focus on entire educational
programmes instead: First, over the last thirty years or so, learning theories
are increasingly stressing the importance of (a) social-material contexts (McInerney
& van Etten, 2002) as well as (b) learners'' subjective experiences. This suggests
that a course of study be not regarded as a mere addition of more or less independent
courses, but rather as a holistic learning experience. This includes the sum total
of a student''s educationally purposeful social-material interactions at a HEI
both within and outside the classroom (cf. Hu & Kuh, 2002). A second, more practical
reason why educational researchers and designers should take a closer look on
the design of educational programmes lies in the Bologna process: The introduction
of the European Credit Transfer System as well as the tow-tiered study structure
force HEI to systematically craft their programmes'' internal structure. Due to
the fact that there are virtually no pedagogical concepts concerning the design
of study programmes, these design processes have so far been dominated by administrative
considerations, largely neglecting students'' experiences within the programme
structures (Winter, 2009; Hildbrand, Tremp, Jäger & Tückmantel, 2008). Thus, it
can be concluded that there is a lack of knowledge on how distinctive design features
of study programmes (1) are perceived by students and (2) impact on their action
strategies concerning for example the selection of learning activities, the attribution
of resources for learning, and social interactions with their peers.'

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: Self-optimizing systems are able to adapt their behavior autonomously according
to their current self-determined objectives. Unforeseen influences could lead
to dependability-critical behavior of the system. Methods are required which secure
self-optimizing systems during operation. These methods to increase the dependability
of the system should already be taken into consideration in the design process.
This paper presents a guideline for the dependability-oriented design of self-optimizing
systems, which integrates established classical methods like failure mode and
effects analysis as well as methods based on self-optimization. On the one hand
self-optimization is used to increase the dependability of the system by integrating
objectives like safety, availability, and reliability to the objectives of the
system. On the other hand methods are required to ensure the self-optimization
itself. As basis for this guideline serves the principle solution of the system.
The six phases of the guideline extend the design process and lead to an enhanced
principle solution. Additionally, the guideline illustrates phases to implement
and validate the self-optimizing system. The proposed guideline is applied to
an innovative rail-bound vehicle, called RailCab, which is equipped with self-optimizing
function modules.

text: In this paper we propose to employ directional statistics in a complex vector
space to approach the problem of blind speech separation in the presence of spatially
correlated noise. We interpret the values of the short time Fourier transform
of the microphone signals to be draws from a mixture of complex Watson distributions,
a probabilistic model which naturally accounts for spatial aliasing. The parameters
of the density are related to the a priori source probabilities, the power of
the sources and the transfer function ratios from sources to sensors. Estimation
formulas are derived for these parameters by employing the Expectation Maximization
(EM) algorithm. The E-step corresponds to the estimation of the source presence
probabilities for each time-frequency bin, while the M-step leads to a maximum
signal-to-noise ratio (MaxSNR) beamformer in the presence of uncertainty about
the source activity. Experimental results are reported for an implementation in
a generalized sidelobe canceller (GSC) like spatial beamforming configuration
for 3 speech sources with significant coherent noise in reverberant environments,
demonstrating the usefulness of the novel modeling framework.

text: The interconnection of software components is a key to enabling collaborative
work. However, technology differences and security barriers like firewalls often
hinder establishing collaborative infrastructures between enterprises or even
within a single enterprise. We introduce a peer-to-peer based network infrastructure
that transparently overcomes these problems using relay and routing mechanisms
as well as different underlying transport protocols. We discuss the application
of this technology to interconnect Web services.
