  text: Despite the rapid growth and potential of technology-based services, managers'
    greatest challenges are gaining customer acceptance and increasing usage of these
    new innovative services. In the B2C field, studies of self-service technology
    show that perceived risk is an important factor influencing the use of service
    technology. Though prior research explores different risk types that emerge in
    consumer settings, risk perception in the B2B setting lacks a detailed examination
    of different risk types influencing technology-based service adoption. Data from
    49 qualitative interviews with providers and customers in two different B2B industries
    inform this study. The findings emphasize the importance of functional and financial
    risks in a B2B context and show that business customers' personal and psychological
    fears hinder their use of technology-based services. Results highlight differences
    in risk perception and evaluation between customers and providers.

  text: 'Despite the growing literature on loyalty program (LP) research, many questions
    remain underexplored. Driven by advancements in information technology, marketing
    analytics, and consumer interface platforms (e.g., mobile devices), there have
    been many recent developments in LP practices around the world. They impose new
    challenges and create exciting opportunities for future LP research. The main
    objective of this paper is to identify missing links in the literature and to
    craft a future research agenda to advance LP research and practice. Our discussion
    focuses on three key areas: (1) LP designs, (2) Assessment of LP performance,
    and (3) Emerging trends and the impact of new technologies. We highlight several
    gaps in the literature and outline research opportunities in each area.'

  text: The protection of information technology (IT) has become and is predicted
    to remain a key economic challenge for organizations. While research on IT security
    investment is fast growing, it lacks a theoretical basis for structuring research,
    explaining economic-technological phenomena and guide future research. We address
    this shortcoming by suggesting a new theoretical model emerging from a multi-theoretical
    perspective adopt-ing the Resource-Based View and the Organizational Learning
    Theory. The joint appli-cation of these theories allows to conceptualize in one
    theoretical model the organiza-tional learning effects that occur when the protection
    of organizational resources through IT security countermeasures develops over
    time. We use this model of IT security invest-ments to synthesize findings of
    a large body of literature and to derive research gaps. We also discuss managerial
    implications of (closing) these gaps by providing practical ex-amples.

  text: Literature reviews play an important role in the development of knowledge.
    Yet, we observe a lack of theoretical underpinning of and epistemological insights
    into how literature reviews can contribute to knowledge creation and have actually
    contributed in the IS discipline. To address these theoretical and empirical research
    gaps, we suggest a novel epistemological model of literature reviews. This model
    allows us to align different contributions of literature reviews with their underlying
    knowledge conversions - thereby building a bridge between the previously largely
    unconnected fields of literature reviews and epistemology. We evaluate the appropriateness
    of the model by conducting an empirical analysis of 173 IS literature reviews
    which were published in 39 pertinent IS journals between 2000 and 2014. Based
    on this analysis, we derive an epistemological taxonomy of IS literature reviews,
    which complements previously suggested typologies.

  text: 'The majority of algorithms can be controlled or adjusted by parameters. Their
    values can substantially affect the algorithms’ performance. Since the manual
    exploration of the parameter space is tedious – even for few parameters – several
    automatic procedures for parameter tuning have been proposed. Recent approaches
    also take into account some characteristic properties of the problem instances,
    frequently termed instance features. Our contribution is the proposal of a novel
    concept for feature-based algorithm parameter tuning, which applies an approximating
    surrogate model for learning the continuous feature-parameter mapping. To accomplish
    this, we learn a joint model of the algorithm performance based on both the algorithm
    parameters and the instance features. The required data is gathered using a recently
    proposed acquisition function for model refinement in surrogate-based optimization:
    the profile expected improvement. This function provides an avenue for maximizing
    the information required for the feature-parameter mapping, i.e., the mapping
    from instance features to the corresponding optimal algorithm parameters. The
    approach is validated by applying the tuner to exemplary evolutionary algorithms
    and problems, for which theoretically grounded or heuristically determined feature-parameter
    mappings are available.'

  text: 'Auseinandersetzungen über Forschungsmethodologien haben in den Bildungswissenschaften
    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: Natural disasters, including earthquakes, Tsunamis, floods, hurricanes, and
    volcanic eruptions, have caused tremendous harm and continue to threaten millions
    of humans and various infrastructure capabilities each year. In their efforts
    to take countermeasures against the threats posed by future natural disasters,
    the United Nations formulated the ?Hyogo Framework for Action?, which aims at
    assessing and reducing risk. This framework and a global review of disaster reduction
    initiatives of the United Nations acknowledge the need for information systems
    research contributions in addressing major challenges of natural disaster management.
    In this paper, we provide a review of the literature with regard to how information
    systems research has addressed risk assessment and reduction in natural disaster
    management. Based on the review we identify research gaps that are centered around
    the need for acquiring general knowledge on how to design IS artifacts for risk
    assessment and reduction. In order to close these gaps in further research, we
    develop a research agenda that follows the IS design science paradigm.

  text: 'In this contribution we present a theoretical and experimental investigation
    into the effects of reverberation and noise on features in the logarithmic mel
    power spectral domain, an intermediate stage in the computation of the mel frequency
    cepstral coefficients, prevalent in automatic speech recognition (ASR). Gaining
    insight into the complex interaction between clean speech, noise, and noisy reverberant
    speech features is essential for any ASR system to be robust against noise and
    reverberation present in distant microphone input signals. The findings are gathered
    in a probabilistic formulation of an observation model which may be used in model-based
    feature compensation schemes. The proposed observation model extends previous
    models in three major directions: First, the contribution of additive background
    noise to the observation error is explicitly taken into account. Second, an energy
    compensation constant is introduced which ensures an unbiased estimate of the
    reverberant speech features, and, third, a recursive variant of the observation
    model is developed resulting in reduced computational complexity when used in
    model-based feature compensation. The experimental section is used to evaluate
    the accuracy of the model and to describe how its parameters can be determined
    from test data.'

  text: Designbasierte Forschung zielt darauf, praktische Problemstellungen zu lösen
    und gleichzeitig wissenschaftliche Theorien (weiter) zu entwickeln. Dabei durchläuft
    designbasierte Forschung in der Regel die Phasen der Problemdefinition, der Entwicklung
    eines didaktischen Designs, der zyklischen Design-Implementation sowie der Evaluation
    und Reflexion in enger Kooperation von Wissenschaft und Praxis. Inwieweit es mittels
    designbasierter Forschung gelingen kann, wissenschaftliche Gültigkeit und praktische
    Relevanz von Forschung gleichermassen zu steigern, wird im Beitrag anhand des
    Konzepts multipler Signifikanzen erörtert. Dabei wird diskutiert, wie die Gestaltung
    der Kooperation von Forschenden und Praktikern/-innen dazu beitragen kann, die
    praktische, statistische, klinische und wirtschaftliche Signifikanz des designbasierten
    Forschungsprozesses sicherzustellen.

  text: The ever-increasing complexity of heterogeneous electronic systems demand
    for intensified abstraction and automation efforts to improve design, verification
    and validation productivity, especially in earlier phases of system engineering.
    Within the verification activity various metrics can be applied to determine functional
    correctness or the overall progress. Here, a supporting verification methodology
    defining high-level verification planning down to the actual metric code development
    is essential. Moreover, an advanced assistance for the designer, such as a tooling
    infrastructure to automatize and accelerate the metric code implementation, is
    needed to minimize the influence of errorprone manual coding. In this article
    we present a single-source verification metric code-generation methodology for
    improved coverage automation. We determine (i) a suitable metric model for model-based
    capture of verification metrics as well as (ii) an assisted model-based processing
    and generation flow of the verification environment and metric skeletons. We apply
    our method to a SystemC case-study, in doing so, targeting metric code implementation
    productivity and consistency enhancement.

    For SoC prototyping, we integrate the fast and open instruction accurate QEMU

  text: "The aim of this qualitative study is first to investigate the attitude development
    of students in their initial year at university. College effectiveness research
    has shown that attitudes towards studying as well as to one's university are key
    factors influencing student engagement. Up to now, little is known about the processes
    through which such attitudes develop. Based on the theory of planned behaviour
    (Ajzen & Fishbein, 1980), the study addresses this research gap in three parts:
    a) development paths of students' attitudes towards studying and the university;
    b) the normative behaviour of the fellow students as well as significant persons,
    c) university-related experiences during the first year influencing students'
    attitude development. \r\nTo answer these research questions, a series of five
    interviews was conducted throughout the first year with a total of 13 first-year
    students at the University of St. Gallen/Switzerland. Data analysis was performed
    referring to the procedures suggested by Neale (2012) for qualitative longitudinal
    data. To master the challenge of displaying developments over time, graphical
    analysis was used to construct a case history (cf. Henderson, Holland et al.,
    2012) for each individual. Regarding the students' developments over time, the
    analysis shows the participants' attitudes towards the university became more
    differentiated over time. A second major result concerns frictions between students'
    own attitudes and what they perceive to be the dominant normative behaviour. It
    became obvious that this developmental process is influenced by concrete incidents
    students experience during the first year and thus, can be shaped by structural
    changes."

  text: In this contribution we derive the Maximum A-Posteriori (MAP) estimates of
    the parameters of a Gaussian Mixture Model (GMM) in the presence of noisy observations.
    We assume the distortion to be white Gaussian noise of known mean and variance.
    An approximate conjugate prior of the GMM parameters is derived allowing for a
    computationally efficient implementation in a sequential estimation framework.
    Simulations on artificially generated data demonstrate the superiority of the
    proposed method compared to the Maximum Likelihood technique and to the ordinary
    MAP approach, whose estimates are corrected by the known statistics of the distortion
    in a straightforward manner.

  text: In this contribution we extend a previously proposed Bayesian approach for
    the enhancement of reverberant logarithmic mel power spectral coefficients for
    robust automatic speech recognition to the additional compensation of background
    noise. A recently proposed observation model is employed whose time-variant observation
    error statistics are obtained as a side product of the inference of the a posteriori
    probability density function of the clean speech feature vectors. Further a reduction
    of the computational effort and the memory requirements are achieved by using
    a recursive formulation of the observation model. The performance of the proposed
    algorithms is first experimentally studied on a connected digits recognition task
    with artificially created noisy reverberant data. It is shown that the use of
    the time-variant observation error model leads to a significant error rate reduction
    at low signal-to-noise ratios compared to a time-invariant model. Further experiments
    were conducted on a 5000 word task recorded in a reverberant and noisy environment.
    A significant word error rate reduction was obtained demonstrating the effectiveness
    of the approach on real-world data.
