  text: Automatic service composition is still a challengingtask. It is even more
    challenging when dealing witha dynamic market of services for end users. New servicesmay
    enter the market while other services are completelyremoved. Furthermore, end
    users are typically no experts in thedomain in which they formulate a request.
    As a consequence,ambiguous user requests will inevitably emerge and have tobe
    taken into account. To meet these challenges, we proposea new approach that combines
    automatic service compositionwith adaptive service recommendation. A best first
    backwardsearch algorithm produces solutions that are functional correctwith respect
    to user requests. An adaptive recommendationsystem supports the search algorithm
    in decision-making.Reinforcement Learning techniques enable the system to adjustits
    recommendation strategy over time based on user ratings.The integrated approach
    is described on a conceptional leveland demonstrated by means of an illustrative
    example fromthe image processing domain.

  text: "Abstract Summary: Study programs are currently receiving more attention in
    Europe. In consequence, it can be observed that the roles of program development
    and management are professionalized. In the proposed round table, we would like
    to discuss the role of educational developers to support this professionalization
    via measures of training and process support in the light of recent developments
    in Switzerland.\r\n\r\nAbstract Text: Professionalization of program development
    as an institutional responsibility \r\nIn Switzerland, different developments
    in higher education have led to increased attention to the development and management
    of the study programs such as the Bologna process, an increasingly competitive
    environment, the tertiarisation of a number of professions formerly acquired through
    vocational education. Furthermore, the national qualification framework and in
    particular accreditation processes require HEI to demonstrate the effectiveness
    of their activities (e.g., Sursock & Smit, 2010). Many different actors have been
    involved in development processes on the program level but also within educational
    development units. However, so far a systematic discourse on key issues regarding
    the management and development of study programs is missing, not only in German-speaking
    Europe. The following main question will guide the round table session: How can
    educational development give vital impulses for program development?\r\nOur starting
    points are two approaches or frameworks from Swiss HEI: a) the definition of competencies
    for new program professionals at the Zurich University for Teacher Education and
    b) a process for the strategic development of didactically-aligned study programs
    at the University of St. Gallen.\r\n\r\nFramework 1: Competencies for program
    managers\r\nThe experiences with a training program for study program managers
    at the Zurich University for Teacher Education are reported. Over\r\na period
    of four years, a competency profile has been developed and refined. Insights into
    the challenges and struggles of this role\r\nwere gained. Despite diverse job
    characteristics of program managers (often resulting from an institution-specific
    history), there is a\r\ncommon set of competencies necessary to successfully cope
    with organizational complexity such as role competency (Schein, 1992)\r\nand lateral
    leadership (Kühl et al., 2005).\r\nFramework 2: Towards a systematic development
    of study programs\r\nThe second initiative concerns the strategic approach to
    program development implemented at the University of St. Gallen (Brahm &\r\nJenert,
    2013; Jenert, 2011). In this structured process, the program goes through four
    process steps: process initiation, program\r\nanalysis, program development, evaluation
    of the process and results. A major challenge in this process is the role of program\r\nprofessionals.
    The goal is to establish them as change agents for a didactically-aligned study
    program.\r\nOutcome: Role of educational development\r\nAfter briefly introducing
    the two examples, the roles of program professionals and educational development
    in HEI will be discussed.\r\nThe questions guiding the discussion will be:\r\n•
    How can program development be established as a continuing task, closely tied
    to quality development?\r\n• How can the competencies of program professionals
    be developed and the local capacity and ownership be strengthened?\r\n• How can
    educational development support program development and provide vital impulses?\r\nAudience
    Engagement. Depending on the number of participants, first the questions will
    be discussed in groups. To put the results of\r\nthe discussion on record, it
    will be summarized and uploaded in our weblog for further discussion after the
    session."

  text: Das erste Studienjahr wird als wesentlicher Übergang von der Schule in die
    Hochschule angesehen. Im Vordergrund steht dabei häufig die Fragen der Identitätsfindung
    der Studierenden und das "Ankommen" im neuen Lebensabschnitt (Briggs, Clark, &
    Hall, 2012; Scanlon, Rowling, & Weber, 2007). In diesem Zusammenhang werden ganz
    unterschiedliche Aspekte untersucht, z. B. die vorhandenen Lernkompetenzen oder
    das Zeitmanagement der Studierenden (Barron & D'Annunzio-Green, 2009), vorhandene
    Einführungsprogramme an Hochschulen (z.B. Gale & Parker, 2012) oder dem ‚student
    engagement‘ während des ersten Jahres (Krause & Coates, 2008). Obwohl die Motivation
    der Studierenden als starker Prädiktor für die Leistung angesehen wird (z. B.
    Busato, Prins, Elshouta, & Hamaker, 2000), wurde die Motivationsentwicklung im
    ersten Studienjahr bis dato nur selten betrachtet. Die vorliegende Mixed Methods-Studie
    setzt an dieser Forschungslücke an und untersucht die Entwicklung der Studienmotivation
    von Wirtschaftsstudierenden im Verlauf des ersten Studienjahres. Im Rahmen einer
    quantitativen Längsschnittuntersuchung mit drei Messzeitpunkten wird dabei die
    Motivationsentwicklung über die gesamte Studierendenpopulation hinweg erfasst.
    Im Mittelpunkt steht die Frage, wie sich die intrinsische und extrinsische Studienmotivation
    sowie die studienbezogene Selbstwirksamkeit über das erste Studienjahr verändern.
    Zudem wird untersucht, inwiefern verschiedene studienbezogene Variablen (z. B.
    Angst) sich auf die Motivationsentwicklung auswirken. Um vertiefte Erkenntnisse
    über die Bedeutsamkeit verschiedener Gestaltungsmerkmale des ersten Studienjahres
    auf die Motivationsentwicklung der Studierenden zu gewinnen, wurde parallel zur
    quantitativen Untersuchung eine qualitative Längsschnittstudie durchgeführt mit
    dem Ziel, (1) verschiedene Verläufe der Motivationsentwicklung und (2) kritische
    Ereignisse im Eingangsjahr zu identifizieren. Das vorliegende Papier zeigt in
    den folgenden beiden Kapiteln den theoretischen Bezugsrahmen der Studie und die
    methodische Vorgehensweise. Daraufhin werden die Ergebnisse sowohl der quantitativen
    als auch der qualitativen Studie dargestellt und im Rahmen der Diskussion miteinander
    verbunden.

  text: Research on entrepreneurial learning often stresses the role of experience
    and previous knowledge. We aim to advance this perspective by pointing out the
    prerequisites and limitations of experience-based forms of learning and by adapting
    findings from educational psychology to the entrepreneurial context. Developing
    a model of self-regulated entrepreneurial learning (SREL) we pursue a more process
    oriented view of entrepreneurial learning in order to explain how learning unfolds
    in contexts of uncertainty and novelty when relevant experience and knowledge
    are scarce. The model comprises a planning, a performance and a review phase in
    order to support entrepreneurs in their learning process. It is suggested how
    SREL is related to self-efficacy, emotions and cognitive biases.

  text: The transition from school to university can be overwhelming for some students.
    While students' motivation is considered a strong predictor of performance, the
    development of motivation during students' transition from high school to university
    has rarely been investigated. Additionally, little is known about the relation
    of motivational aspects with other influences on study performance. The present
    mixed methods study addresses this research gap and examines the development of
    economics students' study motivation. The longitudinal mixed-method study included
    three waves of data collected using quantitative surveys and a series of five
    interviews conducted with 14 first-year students over eight months. Regarding
    students' development over time, the quantitative analysis showed a gradual decline
    in students' motivation. However, in the interviews, certain events during the
    first year were identified as critical incidents demotivating students. These
    insights into the development of students' motivation at a business school show
    that concrete incidents influence students' motivational development; thus, they
    could be transformed by structural changes.

  text: "Tertiary education comprises at least two phases, undergraduate and graduate
    studies. Often, the first year is regarded another, crucial phase where students
    familiarize with the study environment. It can be hypothesized that students'
    individual perceptions of learning and studying as well as the pedagogies they
    experience differ depending on their current study phase. Yet, differences between
    the phases in HE have rarely been investigated. To capture differences in student
    experiences in HE comprehensively, Jenert and Gebhardt (2010) have developed a
    framework describing Learning Culture in HEI. LC comprises a number of constructs
    on the three levels of the individual student, pedagogical interactions and the
    organization.\r\nThe study first aims to quantitatively describe differences in
    LC between the phases of HE within a university. Based on this analysis, a second
    goal is to develop a deeper understanding of how students manage the transitions
    between different phases by applying qualitative research methods."

    lange Tradition. Sie werden häufig unversöhnlich und mit Profilierung der Gegensätze
    geführt. Für uns hängt die Sinnhaftigkeit einer Forschungskonzeption von der Problemstellung
    und dem Erkenntnisinteresse ab. Dies gilt auch für Design-Based Research (DBR).
    Dieser Ansatz entstand als Reaktion auf die Kritik an mangelnder praktischer Anwendung
    von Befunden aus der empirisch-analytischen Lehr-Lernforschung. Als Ergebnis werden
    Theorien angestrebt, die für die Praxis einen Nutzen bieten und zugleich über
    die Anwendung in einer singulären Situation hinausgehen. Wir wollen folgenden
    Fragen nachgehen: Wo liegen die Gemeinsamkeiten, wo die Spezifika von DBR gegenüber
    bestehenden Methodologien? Wie wird der Generalisierungsanspruch von Theorien
    innerhalb von DBR verstanden und umgesetzt? Für welche Erkenntnisinteressen eignet
    sich DBR? Welche Methoden sind für DBR sinnvoll und können wie angewendet werden?'

  text: Cloud computing resulted in a continuously growing number of provided software
    services to be used by consumers. Brokers discover services that fit best to consumers'
    requirements by matching Qualityof-Service (QoS) properties. In order to negotiate
    Service-Level Agreements (SLAs), a provider has to determine the provided QoS
    based on QoS analyses. However, the risk for the provider to violate the SLA is
    high as the service's actual quality can deviate from the specified QoS due to
    uncertainties that occur during the provider's quality analysis. In this paper,
    we discuss current software engineering paradigms like cloud computing and service-oriented
    computing with respect to the amount of uncertainty they induce into service matching
    and SLA negotiations. As a result, we explain, why cloud computing reduces such
    uncertainties.

  text: 'Configurable program analysis (CPA) is a generic concept for the formalization
    of different software analysis techniques in a single framework. With the tool
    CPAchecker, this framework allows for an easy configuration and subsequent automatic
    execution of analysis procedures ranging from data-flow analysis to model checking.
    The focus of the tool CPAchecker is thus on analysis. In this paper, we study
    configurability from the point of view of software certification. Certification
    aims at providing (via a prior analysis) a certificate of correctness for a program
    which is (a) tamper-proof and (b) more efficient to check for validity than a
    full analysis. Here, we will show how, given an analysis instance of a CPA, to
    construct a corresponding sound certification instance, thereby arriving at configurable
    program certification. We report on experiments with certification based on different
    analysis techniques, and in particular explain which characteristics of an underlying
    analysis allow us to design an efficient (in the above (b) sense) certification
    procedure. '

  text: We introduce the concept of budget games. Players choose a set of tasks and
    each task has a certain demand on every resource in the game. Each resource has
    a budget. If the budget is not enough to satisfy the sum of all demands, it has
    to be shared between the tasks. We study strategic budget games, where the budget
    is shared proportionally. We also consider a variant in which the order of the
    strategic decisions influences the distribution of the budgets. The complexity
    of the optimal solution as well as existence, complexity and quality of equilibria
    are analysed. Finally, we show that the time an ordered budget game needs to convergence
    towards an equilibrium may be exponential.

  text: Today's networks, like the Internet, do not consist of one but a mixture of
    several interconnected networks. Each has individual qualities and hence the performance
    of a network node results from the networks' interplay.We introduce a new game
    theoretic model capturing the interplay between a high-speed backbone network
    and a low-speed general purpose network. In our model, n nodes are connected by
    a static network and each node can decide individually to become a gateway node.
    A gateway node pays a fixed price for its connection to the high-speed network,
    but can utilize the high-speed network to gain communication distance 0 to all
    other gateways. Communication distances in the low-speed network are given by
    the hop distances. The effective communication distance between any two nodes
    then is given by the shortest path, which is possibly improved by using gateways
    as shortcuts.Every node v has the objective to minimize its communication costs,
    given by the sum (SUM-game) or maximum (MAX-game) of the effective communication
    distances from v to all other nodes plus a fixed price \alpha > 0, if it decides
    to be a gateway. For both games and different ranges of \alpha, we study the existence
    of equilibria, the price of anarchy, and convergence properties of best-response
    dynamics.

  text: In this paper we study the potential function in congestion games. We consider
    both games with non-decreasing cost functions as well as games with non-increasing
    utility functions. We show that the value of the potential function $\Phi(\sf
    s)$ of any outcome $\sf s$ of a congestion game approximates the optimum potential
    value $\Phi(\sf s^*)$ by a factor $\Psi_{\mathcal{F}}$ which only depends on the
    set of cost/utility functions $\mathcal{F}$, and an additive term which is bounded
    by the sum of the total possible improvements of the players in the outcome $\sf
    s$. The significance of this result is twofold. On the one hand it provides \emph{Price-of-Anarchy}-like
    results with respect to the potential function. On the other hand, we show that
    these approximations can be used to compute $(1+\varepsilon)\cdot\Psi_{\mathcal{F}}$-approximate
    pure Nash equilibria for congestion games with non-decreasing cost functions.
    For the special case of polynomial cost functions, this significantly improves
    the guarantees from Caragiannis et al. [FOCS 2011]. Moreover, our machinery provides
    the first guarantees for general latency functions.

  text: We study the existence of approximate pure Nash equilibria in weighted congestion
    games and develop techniques to obtain approximate potential functions that prove
    the existence of alpha-approximate pure Nash equilibria and the convergence of
    alpha-improvement steps. Specifically, we show how to obtain upper bounds for
    approximation factor alpha for a given class of cost functions. For example for
    concave cost functions the factor is at most 3/2, for quadratic cost functions
    it is at most 4/3, and for polynomial cost functions of maximal degree d it is
    at at most d + 1. For games with two players we obtain tight bounds which are
    as small as for example 1.054 in the case of quadratic cost functions.

  text: We study the existence of approximate pure Nash equilibriain social context
    congestion games. For any given set of allowed costfunctions F, we provide a threshold
    value μ(F), and show that for theclass of social context congestion games with
    cost functions from F, α-Nash dynamics are guaranteed to converge to α-approximate
    pure Nashequilibrium if and only if α > μ(F).Interestingly, μ(F) is related and
    always upper bounded by Roughgarden’sanarchy value [19].

  text: Automatically composing service-based software solutionsis still a challenging
    task. Functional as well as nonfunctionalproperties have to be considered in order
    to satisfyindividual user requests. Regarding non-functional properties,the composition
    process can be modeled as optimization problemand solved accordingly. Functional
    properties, in turn, can bedescribed by means of a formal specification language.
    Statespacebased planning approaches can then be applied to solvethe underlying
    composition problem. However, depending on theexpressiveness of the applied formalism
    and the completenessof the functional descriptions, formally equivalent services
    maystill differ with respect to their implemented functionality. As aconsequence,
    the most appropriate solution for a desired functionalitycan hardly be determined
    without considering additionalinformation. In this paper, we demonstrate how to
    overcome thislack of information by means of Reinforcement Learning. Inorder to
    resolve ambiguity, we expand state-space based servicecomposition by a recommendation
    mechanism that supportsdecision-making beyond formal specifications. The recommendationmechanism
    adjusts its recommendation strategy basedon feedback from previous composition
    runs. Image processingserves as case study. Experimental results show the benefit
    of ourproposed solution.
