  text: Computational Galois theory, in particular the problem of computing the Galois
    group of a given polynomial, is a very old problem. Currently, the best algorithmic
    solution is Stauduhar’s method. Computationally, one of the key challenges in
    the application of Stauduhar’s method is to find, for a given pair of groups H<G,
    a G-relative H-invariant, that is a multivariate polynomial F that is H-invariant,
    but not G-invariant. While generic, theoretical methods are known to find such
    F, in general they yield impractical answers. We give a general method for computing
    invariants of large degree which improves on previous known methods, as well as
    various special invariants that are derived from the structure of the groups.
    We then apply our new invariants to the task of computing the Galois groups of
    polynomials over the rational numbers, resulting in the first practical degree
    independent algorithm.

  text: Suppose Q is a definite quadratic form on a vector space V over some totally
    real field K ≠ Q. Then the maximal integral Zₖ-lattices in (V,Q) are locally isometric
    everywhere and hence form a single genus. We enumerate all orthogonal spaces (V,Q)
    of dimension at least 3, where the corresponding genus of maximal integral lattices
    consists of a single isometry class. It turns out, there are 471 such genera.
    Moreover, the dimension of V and the degree of K are bounded by 6 and 5 respectively.
    This classification also yields all maximal quaternion orders of type number one.

    for discrete free subgroups of rank 2 in PSL₂(R) or SL₂(R). This algorithm, together
    with methods for checking whether a two-generator subgroup of PSL₂(R) or SL₂(R)
    is discrete and free, have been implemented in Magma for groups defined over real

  text: "The purpose of the research was to develop and validate an instrument for
    the assessment of attitudes towards the study environment in higher education
    contexts. The questionnaire is designed to measure students' attitudes towards
    two particular objects: the university (or Higher Education Institution) and the
    process of studying. Five studies at two different universities were conducted
    to develop and validate the Attitudes towards the Study Environment Questionnaire
    (ASEQ). In total, 1640 students filled in the questionnaire. Reliability tests
    and exploratory factor analysis as well as confirmatory factor analysis showed
    satisfactory psychometric characteristics of the ASEQ. Each part of the questionnaire
    is internally consistent and construct validity of the scales is supported by
    correlations with other constructs as assumed by current theories: Positive attitudinal
    constructs (normative behavior, autonomy, joy, self-efficacy, and task value)
    are positively related to intrinsic motivation and the expected study performance
    while anxiety is negatively related to these constructs. \r\nSince attitudes towards
    the study situation are connected to student engagement and motivation, the study
    contributes to the theory of student learning by providing a validated instrument
    to assess attitudes. Thus, the ASEQ can support further research on student performance
    and development by providing an instrument for the hitherto neglected but nonetheless
    extremely relevant domain of attitudes. Also, the questionnaire can be used as
    a diagnostic instrument for higher education faculty and administration to trace
    students' attitudinal development over time - a factor of prime importance for
    student socialization during the introductory phase of studying."

  text: 'Die vorliegende Untersuchung an der Universität St. Gallen soll Erkenntnisse
    über die Verläufe der Einstellungsveränderungen der Studierenden geben (vgl. Brahm
    & Jenert, 2012). Basierend auf der Theorie des geplanten Verhaltens (Ajzen & Fishbein,
    1980) werden drei Forschungsfragen adressiert: (1) Gibt es typische Pfade der
    Einstellungsentwicklung? (2) Wie wird das normative Verhalten von Mitstudierenden
    und anderen Personen wahrgenommen? (3) Welche Erfahrungen beeinflussen die Entwicklung?
    Zur Beantwortung dieser Fragen wurde über das erste Studienjahr hinweg eine Interviewserie
    mit 13 Studierenden durchgeführt. Die Datenanalyse mithilfe grafischer Case Histories
    zeigt, dass die Einstellungen der Probanden über die Zeit differenzierter werden.
    Zudem gibt es Widersprüche zwischen den Einstellungen und dem wahrgenommenen normativen
    Verhalten. Dabei ist die Einstellungsentwicklung von konkreten Ereignissen geprägt
    und kann damit durch strukturelle Interventionen beeinflusst werden.'

  text: The accuracy of automatic speech recognition systems in noisy and reverberant
    environments can be improved notably by exploiting the uncertainty of the estimated
    speech features using so-called uncertainty-of-observation techniques. In this
    paper, we introduce a new Bayesian decision rule that can serve as a mathematical
    framework from which both known and new uncertainty-of-observation techniques
    can be either derived or approximated. The new decision rule in its direct form
    leads to the new significance decoding approach for Gaussian mixture models, which
    results in better performance compared to standard uncertainty-of-observation
    techniques in different additive and convolutive noise scenarios.

  text: In this paper we present a speech presence probability (SPP) estimation algorithmwhich
    exploits both temporal and spectral correlations of speech. To this end, the SPP
    estimation is formulated as the posterior probability estimation of the states
    of a two-dimensional (2D) Hidden Markov Model (HMM). We derive an iterative algorithm
    to decode the 2D-HMM which is based on the turbo principle. The experimental results
    show that indeed the SPP estimates improve from iteration to iteration, and further
    clearly outperform another state-of-the-art SPP estimation algorithm.

  text: "We give an enumeration of all positive definite primitive Z-lattices in dimension
    n ≥ 3 whose genus consists of a single isometry class. This is achieved by using
    bounds obtained from the Smith–Minkowski–Siegel mass formula to computationally
    construct the square-free determinant lattices with this property, and then repeatedly
    calculating pre-images under a mapping first introduced by G. L. Watson.\r\n\r\nWe
    hereby complete the classification of single-class genera in dimensions 4 and
    5 and correct some mistakes in Watson’s classifications in other dimensions. A
    list of all single-class primitive Z-lattices has been compiled and incorporated
    into the Catalogue of Lattices."

  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.
