  text: Users prefer natural language software requirements because of their usability
    and accessibility. When they describe their wishes for software development, they
    often provide off-topic information. We therefore present an automated approach
    for identifying and semantically annotating the on-topic parts of the given descriptions.
    It is designed to support requirement engineers in the requirement elicitation
    process on detecting and analyzing requirements in user-generated content. Since
    no lexical resources with domain-specific information about requirements are available,
    we created a corpus of requirements written in controlled language by instructed
    users and uncontrolled language by uninstructed users. We annotated these requirements
    regarding predicate-argument structures, conditions, priorities, motivations and
    semantic roles and used this information to train classifiers for information
    extraction purposes. The approach achieves an accuracy of 92% for the on- and
    off-topic classification task and an F1-measure of 72% for the semantic annotation.

  text: Die (Wieder-)Einführung einer Vermögensteuer ist in den vergangenen Jahren
    erneut in den Fokus der politischen Diskussion gerückt. Der vorliegende Beitrag
    vermittelt einen Eindruck von den Belastungswirkungen, die aus der Umsetzung von
    aktuell vorliegenden Besteuerungskonzepten resultieren würden. Auf der Basis von
    realen Jahresabschlussdaten wird eine mehrperiodige Veranlagungssimulation durchgeführt,
    die insbesondere ermöglicht, den zu erwartenden Eigenkapitalverzehr sowie den
    Anstieg der Steuerbelastung für die betrachtete Stichprobe zu quantifizieren.
    Von besonderem Interesse sind hierbei Unternehmen, deren laufende Erträge nicht
    ausreichen, um die Belastungen durch die Vermögensteuer zu tragen und damit einem
    Substanzverzehr ausgesetzt sind. Es zeigt sich, dass etwa die Hälfte der Unternehmen
    im Untersuchungszeitraum von sechs Jahren in mindestens einem Jahr einen Substanzverzehr
    erfährt. Der Vermögensteuer kommt somit keinesfalls der vielfach postulierte Charakter
    einer eher mäßig belastenden und im Wesentlichen substanzverschonenden Steuer
    zu. Zusatzbelastungen von knapp 100 bis zu 300 % der Ertragsteuerlast sind keine
    Seltenheit und veranschaulichen das Gefährdungspotenzial dieser Steuer für den
    Wirtschaftsstandort Deutschland.

  text: The (re-)introduction of a wealth tax has again become the subject of political
    debate in recent years. This paper analyzes the impact of implementing the concepts
    under discussion on the overall tax burden and on companies’ equity. Simulating
    a tax assessment based on real annual financial statement data from German listed
    firms in a multi-period setting, we quantify the expected equity erosion as well
    as the increase in the tax burden for the companies in our sample that is induced
    by wealth taxation at the corporate and shareholder level. Special attention is
    given to companies whose current yield is very low and thus would have to take
    additional loans or liquidate assets to settle their wealth tax bill. Our findings
    indicate that around half of the companies would suffer from wealth tax-induced
    asset erosion in at least one year within the six-year period under review. In
    contrast to the usually postulated moderate effects of a wealth tax on firms,
    we find evidence that the additional burden arising from wealth taxation could
    realistically range from nearly 100 to 300 % of the profit tax burden, highlighting
    the magnitude of risk associated with wealth taxation for Germany as a business
    location.

  text: "We study the willingness to compete in a cognitive task among an entire cohort\r\nof
    fresh man business and economics students. Combining data from a lab-in-thefield\r\nexperiment
    with university admissions data, we trace the gender gap in\r\ncompetitiveness
    at different levels of high school performance. Our results confirm\r\nthat, on
    average, men choose to compete more often. The gender gap disappears,\r\nhowever,
    among students with above average high school performance. Female high\r\nschool
    top performers are equally competitive as their male counterparts. In fact,\r\nthe
    overall gender gap is entirely driven by the group of female high school underperformers\r\nwho
    shied away from competition, even when they performed well in our\r\ntask. Overall,
    our findings suggest that high school grades are more than just a\r\nsignal of
    cognitive abilities, because they seem to influence the receivers selfperception\r\nof
    his or her performance in a competitive environment involved in later\r\non in
    life."

  text: The Service Programming and Orchestration for Virtualised Software Networks
    (SONATA) project targets both the flexible programmability of software networks
    and the optimisation of their deployments by means of integrating Development
    and Operations in order to accelerate industry adoption of software networks and
    reduce time-to-market for networked services. SONATA supports network function
    chaining and orchestration, making service platforms modular and easier to customise
    to the needs of different service providers, and introduces a specialised Development
    and Operations model for supporting developers.

  text: "Allocating resources to virtualized network functions and services to meet
    service level agreements is a challenging task for NFV management and orchestration
    systems. This becomes even more challenging when agile development methodologies,
    like DevOps, are applied. In such scenarios, management and orchestration systems
    are continuously facing new versions of functions and services which makes it
    hard to decide how much resources have to be allocated to them to provide the
    expected service performance. \r\nOne solution for this problem is to support
    resource allocation decisions with performance behavior information obtained by
    profiling techniques applied to such network functions and services.\r\n\r\nIn
    this position paper, we analyze and discuss the components needed to generate
    such performance behavior information within the NFV DevOps workflow. We also
    outline research questions that identify open issues and missing pieces for a
    fully integrated NFV profiling solution. Further, we introduce a novel profiling
    mechanism that is able to profile virtualized network functions and entire network
    service chains under different resource constraints before they are deployed on
    production infrastructure."

  text: "Elastic deployments of virtualized network functions~(VNF) can automatically
    scale the amount of used resources in relation to their workload. This is often
    done by starting new VNF instances or stopping old ones. A problem of these scale
    operations is that most network functions are stateful and their internal state
    is not automatically migrated when traffic is redistributed in the deployment.
    As a result, mechanisms are needed to exchange or migrate internal network function
    state between VNF instances.\r\n\r\nThis paper presents a state management framework
    that creates a logically distributed state store on top of elastically deployed
    virtual network functions. We also introduce a novel programming model that provides
    both a local and a global view of the state to each VNF instance. We discuss the
    integration of our framework into existing network function virtualization architectures
    and compare the performance of our prototype to a centralized and a distributed
    state store solution."

  text: "Virtualized network services consisting of multiple individual network functions
    are already today deployed across multiple sites, so called multi-PoP (points
    of presence) environments. This allows to improve service performance by optimizing
    its placement in the network. But prototyping and testing of these complex distributed
    software systems becomes extremely challenging. The reason is that not only the
    network service as such has to be tested but also its integration with management
    and orchestration systems. Existing solutions, like simulators, basic network
    emulators, or local cloud testbeds, do not support all aspects of these tasks.\r\n\r\nTo
    this end, we introduce MeDICINE, a novel NFV prototyping platform that is able
    to execute production-ready network functions, provided as software containers,
    in an emulated multi-PoP environment. These network functions can be controlled
    by any third-party management and orchestration system that connects to our platform
    through standard interfaces. Based on this, a developer can use our platform to
    prototype and test complex network services in a realistic environment running
    on his laptop.\r\n"

  text: CAPTCHAs are challenge-response tests that aim at preventing unwanted machines,
    including bots, from accessing web services while providing easy access for humans.
    Recent advances in artificial-intelligence based attacks show that the level of
    security provided by many state-of-the-art text-based CAPTCHAs is declining. At
    the same time, techniques for distorting and obscuring the text, which are used
    to maintain the level of security, make text-based CAPTCHAs diffcult to solve
    for humans, and thereby further degrade usability. The need for developing alternative
    types of CAPTCHAs which improve both, the current security and usability levels,
    has been emphasized by several researchers. With this study, we contribute to
    research through (1) the development of two new face recognition CAPTCHAs (Farett-Gender
    and Farett-Gender&Age), (2) the security analysis of both procedures, and (3)
    the provision of empirical evidence that one of the suggested CAPTCHAs (Farett-Gender)
    is similar to Google's reCAPTCHA and better than KCAPTCHA concerning effectiveness
    (error rates), superior to both regarding learnability and satisfaction but not
    effciency.

  text: Network function virtualization and software-defined networking allow services
    consisting of virtual network functions to be designed and implemented with great
    flexibility by facilitating automatic deployments, migrations, and reconfigurations
    for services and their components. For extended flexibility, we go beyond seeing
    services as a fixed chain of functions. We present a YANG model for describing
    the service structure in deployment requests in a flexible way that enables changing
    the order of functions in case the order of traversing them does not affect the
    functionality of the service. Upon receiving such requests, the network orchestration
    system can choose the optimal composition of service components that gives the
    best results for placement of services in the network. This introduces new complexities
    to the placement problem by greatly increasing the number of possible ways a service
    can be composed. In this paper, we describe a heuristic solution that selects
    a Pareto set of the possible compositions of a service as well as possible combinations
    of different services, with respect to different resource requirements of the
    services. Our evaluations show that the selected combinations consist of representative
    samples of possible structures and requirements and therefore, can result in optimal
    or close-to-optimal placement results.

  text: 'In this contribution we investigate a priori signal-to-noise ratio (SNR)
    estimation, a crucial component of a single-channel speech enhancement system
    based on spectral subtraction. The majority of the state-of-the art a priori SNR
    estimators work in the power spectral domain, which is, however, not confirmed
    to be the optimal domain for the estimation. Motivated by the generalized spectral
    subtraction rule, we show how the estimation of the a priori SNR can be formulated
    in the so called generalized SNR domain. This formulation allows to generalize
    the widely used decision directed (DD) approach. An experimental investigation
    with different noise types reveals the superiority of the generalized DD approach
    over the conventional DD approach in terms of both the mean opinion score - listening
    quality objective measure and the output global SNR in the medium to high input
    SNR regime, while we show that the power spectrum is the optimal domain for low
    SNR. We further develop a parameterization which adjusts the domain of estimation
    automatically according to the estimated input global SNR. Index Terms: single-channel
    speech enhancement, a priori SNR estimation, generalized spectral subtraction'

  text: This contribution introduces a novel causal a priori signal-to-noise ratio
    (SNR) estimator for single-channel speech enhancement. To exploit the advantages
    of the generalized spectral subtraction, a normalized ?-order magnitude (NAOM)
    domain is introduced where an a priori SNR estimation is carried out. In this
    domain, the NAOM coefficients of noise and clean speech signals are modeled by
    a Weibull distribution and aWeibullmixturemodel (WMM), respectively. While the
    parameters of the noise model are calculated from the noise power spectral density
    estimates, the speechWMM parameters are estimated from the noisy signal by applying
    a causal Expectation-Maximization algorithm. Further a maximum a posteriori estimate
    of the a priori SNR is developed. The experiments in different noisy environments
    show the superiority of the proposed estimator compared to the well-known decision-directed
    approach in terms of estimation error, estimator variance and speech quality of
    the enhanced signals when used for speech enhancement.

  text: A noise power spectral density (PSD) estimation is an indispensable component
    of speech spectral enhancement systems. In this paper we present a noise PSD tracking
    algorithm, which employs a noise presence probability estimate delivered by a
    deep neural network (DNN). The algorithm provides a causal noise PSD estimate
    and can thus be used in speech enhancement systems for communication purposes.
    An extensive performance comparison has been carried out with ten causal state-of-the-art
    noise tracking algorithms taken from the literature and categorized acc. to applied
    techniques. The experiments showed that the proposed DNN-based noise PSD tracker
    outperforms all competing methods with respect to all tested performance measures,
    which include the noise tracking performance and the performance of a speech enhancement
    system employing the noise tracking component.
