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.","lang":"eng"}],"publication":"Proceedings of the 51st Hawaii International Conference on System Sciences","type":"conference","date_created":"2018-10-18T18:18:44Z"},{"project":[{"name":"SFB 901","_id":"1"},{"_id":"2","name":"SFB 901 - Project Area A"},{"name":"SFB 901 - Subproject A3","_id":"7"}],"citation":{"mla":"Hoyer, Britta, and Stephanie Rosenkranz. “ Determinants of Equilibrium Selection in Network Formation - An Experiment.” <i>Games</i>, vol. 9, no. 4, 89, MDPI, 2018.","apa":"Hoyer, B., &#38; Rosenkranz, S.

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.","lang":"eng"}],"publication":"Mathematical and Computational Applications","issue":"2","type":"journal_article","department":[{"_id":"101"}],"date_created":"2019-03-29T13:27:51Z"},{"keyword":["tet_topic_plasmonics"],"type":"journal_article","department":[{"_id":"61"},{"_id":"230"}],"file":[{"date_created":"2018-08-28T07:45:47Z","creator":"hclaudia","file_id":"4166","content_type":"application/pdf","relation":"main_file","date_updated":"2018-09-03T13:54:21Z","file_name":"2018 Myroshnychenko,Nishio,Garcia de Abajo,Förstner,Yamamoto_Unveiling and Imaging Degenerate States in Plasmonic Nanoparticles with Nanometer Resolution.pdf","file_size":4463352,"access_level":"open_access"}],"date_created":"2018-08-28T07:44:24Z","abstract":[{"lang":"eng","text":"Metal nanoparticles host localized plasmon excitations that allow the manipulation of optical fields at the nanoscale. 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.

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."}],"file":[{"creator":"ups","date_created":"2018-11-02T14:32:35Z","file_name":"paper0722.pdf","file_size":753693,"access_level":"closed","relation":"main_file","date_updated":"2018-11-02T14:32:35Z","file_id":"5274","content_type":"application/pdf","success":1}],"date_created":"2017-10-17T12:40:59Z","keyword":["Software Product Lines: Engineering","Services","and Management","Ambiguities","Incompleteness","Natural Language Processing","Software Requirements"],"type":"conference","department":[{"_id":"36"},{"_id":"1"},{"_id":"579"}],"title":"Flexible Ambiguity Resolution and Incompleteness Detection in Requirements Descriptions via an Indicator-based Configuration of Text Analysis Pipelines","year":"2018","publication_identifier":{"isbn":["978-0-9981331-1-9"]},"author":[{"id":"38837","full_name":"Bäumer, Frederik Simon","first_name":"Frederik Simon","last_name":"Bäumer"},{"id":"42496","full_name":"Geierhos, Michaela","first_name":"Michaela","last_name":"Geierhos","orcid":"0000-0002-8180-5606"}],"date_updated":"2022-01-06T07:01:01Z","publication_status":"published","main_file_link":[{"url":"https://scholarspace.manoa.hawaii.edu/bitstream/10125/50609/1/paper0722.pdf","open_access":"1"}],"language":[{"iso":"eng"}],"doi":"10125/50609"},{"type":"working_paper","department":[{"_id":"187"}],"oa":"1","date_created":"2018-10-30T12:14:40Z","abstract":[{"text":"This study analyzes the relation between accounting conservatism, future tax rate cuts and countries’ level of book-tax conformity. 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.","lang":"eng"}],"citation":{"ieee":"T.

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.","lang":"eng"}],"language":[{"iso":"eng"}],"title":"Information Security Investments: An Exploratory Multiple Case Study on Decision-Making, Evaluation and Learning","year":"2018","author":[{"full_name":"Weishäupl, Eva","last_name":"Weishäupl","first_name":"Eva"},{"first_name":"Emrah","last_name":"Yasasin","full_name":"Yasasin, Emrah"},{"first_name":"Guido","last_name":"Schryen","full_name":"Schryen, Guido","id":"72850"}],"date_updated":"2022-01-06T07:02:03Z","intvolume":"        77"},{"file_date_updated":"2018-12-13T15:06:21Z","citation":{"apa":"Schuster, R., Wagner, G., &#38; 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.
