Research shows that increasing transparency to the granularity of individual BI&A artefacts such as reports or analytic applications is a necessary means, but in practice the introduction of said systems is cumbersome and adoption is slow. We address the status quo of BI&A cost accounting for three types of stakeholders: users, developers and managers. The results show in which areas of application a strong need for action exists and we identify major challenges for further research are ahead. Our findings indicate for example that managers at the same time regard cost accounting for BI&A with a higher potential benefit while they also believe they have already established a higher degree of implementation in their enterprises compared to the other stakeholder types. We conclude that BI&A professionals have to consider these different perceptions to run a successful department and gain traction for BI&A cost accounting.' author: - first_name: Raphael full_name: Grytz, Raphael id: '4481' last_name: Grytz - first_name: Artus full_name: Krohn-Grimberghe, Artus last_name: Krohn-Grimberghe citation: ama: 'Grytz R, Krohn-Grimberghe A.

The task in multiobjective optimization and multiobjective optimal control is therefore to compute the set of optimal compromises (the Pareto set) between the conflicting objectives. The advances in algorithms and the increasing interest in Pareto-optimal solutions have led to a wide range of new applications related to optimal and feedback control, which results in new challenges such as expensive models or real-time applicability. Since the Pareto set generally consists of an infinite number of solutions, the computational effort can quickly become challenging, which is particularly problematic when the objectives are costly to evaluate or when a solution has to be presented very quickly. This article gives an overview of recent developments in accelerating multiobjective optimal control for complex problems where either PDE constraints are present or where a feedback behavior has to be achieved. In the first case, surrogate models yield significant speed-ups. Besides classical meta-modeling techniques for multiobjective optimization, a promising alternative for control problems is to introduce a surrogate model for the system dynamics. In the case of real-time requirements, various promising model predictive control approaches have been proposed, using either fast online solvers or offline-online decomposition. We also briefly comment on dimension reduction in many-objective optimization problems as another technique for reducing the numerical effort. article_type: review author: - first_name: Sebastian full_name: Peitz, Sebastian id: '47427' last_name: Peitz orcid: https://orcid.org/0000-0002-3389-793X - first_name: Michael full_name: Dellnitz, Michael last_name: Dellnitz citation: ama: Peitz S, Dellnitz M.

Despite the availability of several techniques for imaging plasmons, direct access into the symmetries of these excitations remains elusive, thus hindering progress in the development of applications. Here, we present a combination of angle-, polarization-, and space-resolved cathodoluminescence spectroscopy methods to selectively access the symmetry and degeneracy of plasmonic states in lithographically fabricated gold nanoprisms. We experimentally reveal and spatially map degenerate states of multipole plasmon modes with nanometer spatial resolution and further provide recipes for resolving optically dark and out-of-plane modes. Full-wave simulations in conjunction with a simple tight-binding model explain the complex plasmon structure in these particles and reveal intriguing mode-symmetry phenomena. Our approach introduces systematics for a comprehensive symmetry characterization of plasmonic states in high-symmetry nanostructures. article_type: original author: - first_name: Viktor full_name: Myroshnychenko, Viktor id: '46371' last_name: Myroshnychenko - first_name: Natsuki full_name: Nishio, Natsuki last_name: Nishio - first_name: F.

However, these descriptions are susceptible to linguistic inaccuracies such as ambiguities and incompleteness that can harm the development process. There is a number of software solutions that can detect deficits in requirements descriptions and partially solve them, but they are often hard to use and not suitable for end users. For this reason, we develop a software system that helps end-users to create unambiguous and complete requirements descriptions by combining existing expert tools and controlling them using automatic compensation strategies. In order to recognize the necessity of individual compensation methods in the descriptions, we have developed linguistic indicators, which we present in this paper. Based on these indicators, the whole text analysis pipeline is ad-hoc configured and thus adapted to the individual circumstances of a requirements description. author: - first_name: Frederik Simon full_name: Bäumer, Frederik Simon id: '38837' last_name: Bäumer - first_name: Michaela full_name: Geierhos, Michaela id: '42496' last_name: Geierhos orcid: 0000-0002-8180-5606 citation: ama: 'Bäumer FS, Geierhos M.

Firms have an incentive to increase conservatism in financial reporting when a tax rate cut is imminent to shift taxable income into the lower taxed future. Using a panel of firms across 18 countries from 1995 to 2010 I find that conditional conservatism is positively and significantly associated with future tax rate cuts when book-tax conformity is high. This effect is particularly pronounced for firms that concentrate the majority of their operations in the country in which the tax rate is cut. In contrast, there is no significant relation between future tax rate cuts and unconditional conservatism. author: - first_name: Tobias full_name: Bornemann, Tobias last_name: Bornemann citation: ama: Bornemann T.

In recent years, this interdisciplinary research has grown significantly covering research with regards to optimal compensation, investment decisions, tax avoidance and transfer pricing while analyzing the effects of corporate income taxes, wage taxes, bonus taxes and shareholder taxes. Our paper provides a comprehensive review of analytical literature that studies the influence of taxation on agency conflicts between firm owners and managers. Above and beyond summarizing research findings, we discuss how taxes are commonly implemented in agency models, derive empirical predictions, and identify research gaps for future tax research. author: - first_name: Thomas full_name: Bauer, Thomas last_name: Bauer - first_name: Thomas full_name: Kourouxous, Thomas id: '66936' last_name: Kourouxous - first_name: Peter full_name: Krenn, Peter last_name: Krenn citation: ama: 'Bauer T, Kourouxous T, Krenn P.

In the presence of budget constraints and a diverse set of assets to protect, organizations have to decide in which IT security measures to invest, how to evaluate those investment decisions, and how to learn from past decisions to optimize future security investment actions. While the academic literature has provided valuable insights into these issues, there is a lack of empirical contributions. To address this lack, we conduct a theory-based exploratory multiple case study. Our case study reveals that (1) firms? investments in information security are largely driven by external environmental and industry-related factors, (2) firms do not implement standardized decision processes, (3) the security process is perceived to impact the business process in a disturbing way, (4) both the implementation of evaluation processes and the application of metrics are hardly existent and (5) learning activities mainly occur at an ad-hoc basis. author: - first_name: Eva full_name: Weishäupl, Eva last_name: Weishäupl - first_name: Emrah full_name: Yasasin, Emrah last_name: Yasasin - first_name: Guido full_name: Schryen, Guido id: '72850' last_name: Schryen citation: ama: 'Weishäupl E, Yasasin E, Schryen G.

In doing so, various optimization objectives are conceivable, e.g., minimizing certain required resources or the end-to-end delay of the placed services.\r\n\r\nIn this paper, we investigate the relationship between four typical optimization objectives when coordinating the placement and resource allocation of chained VNF instances. We observe an interesting trade-off between minimizing the overhead of starting/stopping VNF instances and all other objectives when adapting to changed service demands." author: - first_name: Stefan Balthasar full_name: Schneider, Stefan Balthasar id: '35343' last_name: Schneider orcid: 0000-0001-8210-4011 - first_name: Sevil full_name: Dräxler, Sevil id: '31764' last_name: Dräxler - first_name: Holger full_name: Karl, Holger id: '126' last_name: Karl citation: ama: 'Schneider SB, Dräxler S, Karl H.

This paper presents a placement abstraction\r\nlayer (PAL) that provides a clear and simple northbound interface\r\nfor using such algorithms while hiding their internal\r\nfunctionality and implementation. Through its southbound interface,\r\nPAL can connect to different back ends that evaluate\r\nthe calculated placements, e.g., using simulations, emulations, or\r\ntestbed approaches. As an example for such evaluation back ends,\r\nwe introduce a novel placement emulation framework (PEF)\r\nthat allows executing calculated placements using real, containerbased\r\nVNFs on real-world network topologies. In a case study,\r\nwe show how PAL and PEF facilitate reusing and evaluating\r\nplacement algorithms as well as validating their underlying\r\nmodels and performance claims." author: - first_name: Stefan Balthasar full_name: Schneider, Stefan Balthasar id: '35343' last_name: Schneider orcid: 0000-0001-8210-4011 - first_name: Manuel full_name: Peuster, Manuel id: '13271' last_name: Peuster - first_name: Holger full_name: Karl, Holger id: '126' last_name: Karl citation: ama: 'Schneider SB, Peuster M, Karl H.

Currently, development requires many manual\r\nsteps that are time-consuming and error-prone (e.g., for creating\r\nservice descriptors). Furthermore, existing management and\r\norchestration (MANO) platforms only offer limited support of\r\nstandardized descriptor models or package formats, limiting the\r\nre-usability of network services.\r\n\r\nTo this end, we introduce a fully integrated, open-source\r\nNFV service development kit (SDK) with multi-MANO platform\r\nsupport. Our SDK simplifies many NFV service development\r\nsteps by offering initial generation of descriptors, advanced\r\nproject management, as well as fully automated packaging and\r\nsubmission for on-boarding. To achieve multi-platform support,\r\nwe present a package format that extends ETSI’s VNF package\r\nformat. In this demonstration, we present the end-to-end workflow\r\nto develop an NFV service that is then packaged for multiple\r\nplatforms, i.e., 5GTANGO and OSM." author: - first_name: Stefan Balthasar full_name: Schneider, Stefan Balthasar id: '35343' last_name: Schneider orcid: 0000-0001-8210-4011 - first_name: Manuel full_name: Peuster, Manuel id: '13271' last_name: Peuster - first_name: Wouter full_name: Tavernier, Wouter last_name: Tavernier - first_name: Holger full_name: Karl, Holger id: '126' last_name: Karl citation: ama: 'Schneider SB, Peuster M, Tavernier W, Karl H.

Driven by the DCASE challenges and the availability of large-scale audio datasets, the state-of-the-art has progressed rapidly with deep-learning-based classi- fiers dominating the field. Because several potential use cases favor a realization on distributed sensor nodes, e.g. ambient assisted living applications, habitat monitoring or surveillance, we are concerned with two issues here. Firstly the classification performance of such systems and secondly the computing resources required to achieve a certain performance considering node level feature extraction. In this contribution we look at the balance between the two criteria by employing traditional techniques and different deep learning architectures, including convolutional and recurrent models in the context of real life everyday audio recordings in realistic, however challenging, multisource conditions. author: - first_name: Janek full_name: Ebbers, Janek id: '34851' last_name: Ebbers - first_name: Alexandru full_name: Nelus, Alexandru last_name: Nelus - first_name: Rainer full_name: Martin, Rainer last_name: Martin - first_name: Reinhold full_name: Haeb-Umbach, Reinhold id: '242' last_name: Haeb-Umbach citation: ama: 'Ebbers J, Nelus A, Martin R, Haeb-Umbach R.
