Even in evaluations that do use real-world apps, details about the ground truth in those apps are rarely documented, which makes it difficult to compare and reproduce the results. To push Android taint analysis research forward, this paper thus recommends criteria for constructing real-world benchmark suites for this specific domain, and presents TaintBench, the first real-world malware benchmark suite with documented taint flows. TaintBench benchmark apps include taint flows with complex structures, and addresses static challenges that are commonly agreed on by the community. Together with the TaintBench suite, we introduce the TaintBench framework, whose goal is to simplify real-world benchmarking of Android taint analyses. First, a usability test shows that the framework improves experts’ performance and perceived usability when documenting and inspecting taint flows. Second, experiments using TaintBench reveal new insights for the taint analysis tools Amandroid and FlowDroid: (i) They are less effective on real-world malware apps than on synthetic benchmark apps. (ii) Predefined lists of sources and sinks heavily impact the tools’ accuracy. (iii) Surprisingly, up-to-date versions of both tools are less accurate than their predecessors."}],"ddc":["000"],"user_id":"15249","main_file_link":[{"open_access":"1","url":"https://link.springer.com/content/pdf/10.1007/s10664-021-10013-5.pdf"}],"year":"2021","citation":{"short":"L.

Dabei sind empirische Belege für eine positive Wirksamkeit nach wie vor kaum vorhanden, es gibt sogar Befunde zu ‚negativen‘ Konsequenzen von Lehrkräftekooperation. Um diese Widersprüchlichkeit zu klären, wurde in der vorliegenden Arbeit Kooperation nicht als Instrument bzw. als Technik betrachtet, sondern als soziale Praxis verstanden, in der eigenlogisches, kollektiv-implizites Wissen (re)produziert wird (Community of Practice). Parallel dazu wurde ein praxeologisches Kompetenzverständnis (Praxiskompetenz) eingeführt, das wesentlich auf die Praxeologie Pierre Bourdieus zurückgeht und den Zusammenhang zwischen Lehrkräftekooperation als Community of Practice und kollektiv strukturierter, individueller Kompetenz theoretisch verdeutlicht. Die empirischen Befunde, welche mittels der Dokumentarischen Methode generiert wurden, verweisen auf die Bedeutung unterschiedlicher Relationslogiken (Nicht-Passung, Entfaltung, Herausforderung) für das ‚Lernen‘ von oder innerhalb von Praxiskompetenz(en) und damit auch auf die Wichtigkeit einer grundlegend kollektiv gerahmten Perspektive auf Lehrkräftekooperation. Vor diesem Hintergrund ist ein allzu positiver Blick auf Lehrkräftekooperationsprozesse kritisch zu betrachten."}],"article_type":"review","title":"Entwicklung von Praxiskompetenz durch Kooperationsprozesse von Lehrkräften","user_id":"69383","publication":"Zeitschrift für Bildungsforschung","quality_controlled":"1","author":[{"last_name":"Bloh","full_name":"Bloh, Thiemo","first_name":"Thiemo"}],"publication_identifier":{"issn":["2190-6890","2190-6904"]},"publication_status":"published","date_created":"2021-11-25T18:09:52Z","status":"public"},{"language":[{"iso":"eng"}],"date_updated":"2022-01-06T06:54:44Z","doi":"10.1109/JPROC.2020.3018668","oa":"1","department":[{"_id":"54"}],"project":[{"name":"Computing Resources Provided by the Paderborn Center for Parallel Computing","_id":"52"}],"title":"Far-Field Automatic Speech Recognition","page":"124-148","type":"journal_article","year":"2021","citation":{"short":"R.

Meanwhile it has entered the consumer market with digital home assistants with a spoken language interface being its most prominent application. Speech recorded at a distance is affected by various acoustic distortions and, consequently, quite different processing pipelines have emerged compared to ASR for close-talk speech. A signal enhancement front-end for dereverberation, source separation and acoustic beamforming is employed to clean up the speech, and the back-end ASR engine is robustified by multi-condition training and adaptation. We will also describe the so-called end-to-end approach to ASR, which is a new promising architecture that has recently been extended to the far-field scenario. This tutorial article gives an account of the algorithms used to enable accurate speech recognition from a distance, and it will be seen that, although deep learning has a significant share in the technological breakthroughs, a clever combination with traditional signal processing can lead to surprisingly effective solutions."}],"ddc":["000"],"user_id":"59789"},{"oa":"1","date_updated":"2022-01-06T06:54:49Z","_id":"21204","conference":{"name":"The Thirty-Fifth AAAI Conference on Artificial Intelligence"},"language":[{"iso":"eng"}],"citation":{"bibtex":"@inproceedings{Kucklick_Müller_2021, title={A Comparison of Multi-View Learning Strategies for Satellite Image-based Real Estate Appraisal}, booktitle={ The AAAI-21 Workshop on Knowledge Discovery from Unstructured Data in Financial Services}, author={Kucklick, Jan-Peter and Müller, Oliver}, year={2021} }","mla":"Kucklick, Jan-Peter, and Oliver Müller. “A Comparison of Multi-View Learning Strategies for Satellite Image-Based Real Estate Appraisal.” The AAAI-21 Workshop on Knowledge Discovery from Unstructured Data in Financial Services, 2021.","chicago":"Kucklick, Jan-Peter, and Oliver Müller. “A Comparison of Multi-View Learning Strategies for Satellite Image-Based Real Estate Appraisal.” In The AAAI-21 Workshop on Knowledge Discovery from Unstructured Data in Financial Services, 2021.","ama":"Kucklick J-P, Müller O.

It is targeted at\r\nheterogeneous and expensive problems, i.e., problems that have at least one\r\nobjective function that is computationally expensive. The method is\r\nderivative-free in the sense that neither need derivative information be\r\navailable for the expensive objectives nor are gradients approximated using\r\nrepeated function evaluations as is the case in finite-difference methods.\r\nInstead, a multiobjective trust region approach is used that works similarly to\r\nits well-known scalar pendants. Local surrogate models constructed from\r\nevaluation data of the true objective functions are employed to compute\r\npossible descent directions.

Providing these services requires online coordination including scaling the service, placing instance of all components in the network, scheduling traffic to these instances, and routing traffic through the network. Optimized service coordination is still a hard problem due to many influencing factors such as rapidly arriving user demands and limited node and link capacity. Existing approaches to solve the problem are often built on rigid models and assumptions, tailored to specific scenarios. If the scenario changes and the assumptions no longer hold, they easily break and require manual adjustments by experts. Novel self-learning approaches using deep reinforcement learning (DRL) are promising but still have limitations as they only address simplified versions of the problem and are typically centralized and thus do not scale to practical large-scale networks.\r\n\r\nTo address these issues, we propose a distributed self-learning service coordination approach using DRL. After centralized training, we deploy a distributed DRL agent at each node in the network, making fast coordination decisions locally in parallel with the other nodes. Each agent only observes its direct neighbors and does not need global knowledge. Hence, our approach scales independently from the size of the network. In our extensive evaluation using real-world network topologies and traffic traces, we show that our proposed approach outperforms a state-of-the-art conventional heuristic as well as a centralized DRL approach (60% higher throughput on average) while requiring less time per online decision (1 ms)."}],"language":[{"iso":"eng"}],"oa":"1","date_updated":"2022-01-06T06:55:04Z","project":[{"name":"SFB 901","_id":"1"},{"name":"SFB 901 - Project Area C","_id":"4"},{"_id":"16","name":"SFB 901 - Subproject C4"}],"department":[{"_id":"75"}],"title":"Distributed Online Service Coordination Using Deep Reinforcement Learning","related_material":{"link":[{"url":"https://github.com/ RealVNF/distributed-drl-coordination","relation":"software"}]}},{"intvolume":" 1","_id":"21569","type":"report","year":"2021","citation":{"apa":"Gottschalk, S., & Yigitbas, E.

It describes the problem of splitting a secret into different shares, without revealing any information to its shareholders. Here, we demonstrate an all-optical solution for secret sharing based on metasurface holography. In our concept, metasurface holograms are used as spatially separable shares that carry encrypted messages in the form of holographic images. Two of these shares can be recombined by bringing them close together. Light passing through this stack of metasurfaces accumulates the phase shift of both holograms and optically reconstructs the secret with high fidelity. In addition, the hologram generated by each single metasurface can uniquely identify its shareholder. Furthermore, we demonstrate that the inherent translational alignment sensitivity between two stacked metasurface holograms can be used for spatial multiplexing, which can be further extended to realize optical rulers.","lang":"eng"}],"user_id":"30525","main_file_link":[{"open_access":"1","url":"https://advances.sciencemag.org/content/7/16/eabf9718"}],"citation":{"apa":"Georgi, P., Wei, Q., Sain, B., Schlickriede, C., Wang, Y., Huang, L., & Zentgraf, T.

Here, a mismatch between method and situation can lead to poor resource management and longer development cycles. In software engineering, situational method engineering is used for software projects to configure a development method out of a method repository based on the project situation. Analogously, we support creating situation-specific business model development methods with a method base and new user roles. Here, the method engineer obtains the knowledge of the domain expert and stores it in the method base as elements, building blocks, and patterns. The expert knowledge is derived from a grey literature review on mobile development processes. After this, the method engineer constructs the development method based on the described situation of the business developer.

These techniques encompass host-based intrusion detection systems (HIDSs) that detect suspicious activities in application contexts. Such application-aware HIDSs originate in information and communications technology systems and have a great potential to deal with the flexible nature of application-level software platforms. However, the elementary characteristics of known application-aware HIDS approaches and thereby the implications for their transfer to the automotive sector are unclear. In previous work, we presented a systematic literature review (SLR) covering the state of the art of application-aware HIDS approaches. We synthesized our findings by means of a fine-grained classification for each approach specified through a feature model and corresponding variant models. These models represent the approaches’ elementary characteristics. Furthermore, we summarized key findings and inferred implications for the transfer of application-aware HIDSs to the automotive sector. In this article, we extend the previous work by several aspects. We adjust the quality evaluation process within the SLR to be able to consider high quality conference publications, which results in an extended final pool of publications. For supporting HIDS developers on the task of configuring HIDS analysis techniques based on machine learning, we report on initial results on the applicability of AutoML. Furthermore, we present lessons learned regarding the application of the feature and variant model approach for SLRs. Finally, we more thoroughly describe the SLR study design."}]},{"language":[{"iso":"eng"}],"page":"165-175","type":"conference","citation":{"ieee":"Z. Nouri, U. Gadiraju, G. Engels, and H.

Metrics such as ECT, RNSB, and WEAT quantify bias in these models based on predefined word lists representing social groups and bias-conveying concepts. How suitable these lists actually are to reveal bias - let alone the bias metrics in general - remains unclear, though. In this paper, we study how to assess the quality of bias metrics for word embedding models. In particular, we present a generic method, Bias Silhouette Analysis (BSA), that quantifies the accuracy and robustness of such a metric and of the word lists used. Given a biased and an unbiased reference embedding model, BSA applies the metric systematically for several subsets of the lists to the models. The variance and rate of convergence of the bias values of each model then entail the robustness of the word lists, whereas the distance between the models' values gives indications of the general accuracy of the metric with the word lists. We demonstrate the behavior of BSA on two standard embedding models for the three mentioned metrics with several word lists from existing research."}],"date_created":"2021-05-11T23:13:26Z","status":"public","publication":"Proceedings of the Thirtieth International Joint Conference on Artificial Intelligence, IJCAI-21","department":[{"_id":"600"}],"author":[{"first_name":"Maximilian","orcid":"0000-0003-4364-1409","full_name":"Spliethöver, Maximilian","last_name":"Spliethöver","id":"84035"},{"full_name":"Wachsmuth, Henning","first_name":"Henning","id":"3900","last_name":"Wachsmuth"}],"quality_controlled":"1","oa":"1","doi":"10.24963/ijcai.2021/77","conference":{"end_date":"2021-08-26","start_date":"2021-08-19","name":"30th International Joint Conference on Artificial Intelligence (IJCAI-21)","location":"Online"},"date_updated":"2022-01-06T06:55:28Z","_id":"22156","language":[{"iso":"eng"}],"page":"552-559","citation":{"chicago":"Spliethöver, Maximilian, and Henning Wachsmuth. “Bias Silhouette Analysis: Towards Assessing the Quality of Bias Metrics for Word Embedding Models.” In Proceedings of the Thirtieth International Joint Conference on Artificial Intelligence, IJCAI-21, 552–59, 2021. https://doi.org/10.24963/ijcai.2021/77.","apa":"Spliethöver, M., & Wachsmuth, H.

This kind of nonlinear metasurface allows for substantial second-harmonic generation at normal incidence which is completely absent for an antenna array without the multi-quantum well structure underneath.

The key idea is to let the learner itself iteratively generate \"pseudo-supervision\" for unlabeled instances based on its current hypothesis. In combination with consistency regularization, pseudo-labeling has shown promising performance in various domains, for example in computer vision. To account for the hypothetical nature of the pseudo-labels, these are commonly provided in the form of probability distributions. Still, one may argue that even a probability distribution represents an excessive level of informedness, as it suggests that the learner precisely knows the ground-truth conditional probabilities. In our approach, we therefore allow the learner to label instances in the form of credal sets, that is, sets of (candidate) probability distributions. Thanks to this increased expressiveness, the learner is able to represent uncertainty and a lack of knowledge in a more flexible and more faithful manner. To learn from weakly labeled data of that kind, we leverage methods that have recently been proposed in the realm of so-called superset learning. In an exhaustive empirical evaluation, we compare our methodology to state-of-the-art self-supervision approaches, showing competitive to superior performance especially in low-label scenarios incorporating a high degree of uncertainty.","lang":"eng"}],"type":"preprint","year":"2021","citation":{"ieee":"J.

We proxy individuals' risk perception with their willingness to pay for the participation in everyday life and amusements events. We find that participants react to different COVID-19 metrics with varying sensitivity. We observe a saturation of sensitivity for several measures at critical limits used in the political discussion, making our results highly relevant for policy makers in their efforts to direct individuals to adhere to hygienic etiquette and social distancing guidelines.","lang":"eng"}],"user_id":"67265","main_file_link":[{"open_access":"1","url":"https://cepr.org/file/11142/download?token=wXdlx51o"}],"funded_apc":"1","year":"2021","type":"journal_article","citation":{"short":"S.

These services can scale and run across multiple network nodes on demand. To process incoming traffic, service components have to be instantiated and traffic assigned to these instances, taking capacities, changing demands, and Quality of Service (QoS) requirements into account. This challenge is usually solved with custom approaches designed by experts. While this typically works well for the considered scenario, the models often rely on unrealistic assumptions or on knowledge that is not available in practice (e.g., a priori knowledge).\r\n\r\nWe propose DeepCoord, a novel deep reinforcement learning approach that learns how to best coordinate services and is geared towards realistic assumptions. It interacts with the network and relies on available, possibly delayed monitoring information. Rather than defining a complex model or an algorithm on how to achieve an objective, our model-free approach adapts to various objectives and traffic patterns. An agent is trained offline without expert knowledge and then applied online with minimal overhead. Compared to a state-of-the-art heuristic, DeepCoord significantly improves flow throughput (up to 76%) and overall network utility (more than 2x) on realworld network topologies and traffic traces. It also supports optimizing multiple, possibly competing objectives, learns to respect QoS requirements, generalizes to scenarios with unseen, stochastic traffic, and scales to large real-world networks.

Während die Berufswahlmotivation bereits verstärkt im wirtschaftspädagogischen Kontext untersucht wurde, existieren zum Berufsethos von Wirtschaftspädagog*innen nur vereinzelt empirische Studien. So ist beispielsweise wenig darüber bekannt, wie das Berufsethos von Wirtschaftspädagog*innen in der Ausbildungsphase ausgeprägt ist. Auch die Erforschung des Zusammenhangs zwischen den Konstrukten des Berufsethos und der Berufswahlmotivation blieb bisher unbeachtet. In diesem Beitrag wird entsprechend dieses Forschungsdesiderats untersucht, wie das anfänglich ausgebildete Berufsethos von Wirtschaftspädagogikstudierenden in der universitären Ausbildung ausgeprägt ist, ob sich die Ausprägung nach dem angegebenen Berufswunsch der Studierenden unterscheidet und inwiefern das anfänglich ausgeprägte Berufsethos mit der Berufswahlmotivation von Studierenden zusammenhängt. Dafür wurden im Wintersemester 2019/20 an zwölf deutschen Universitäten insgesamt 879 Wirtschaftspädagogikstudierende schriftlich befragt. Die Ergebnisse zeigen, dass das anfängliche Berufsethos der Befragten bereits in der universitären Ausbildungsphase relativ stark ausgeprägt ist. Weiterhin ist zu erkennen, dass das Berufsethos bei angehenden Wirtschaftspädagog*innen, die den Berufswunsch Lehrkraft haben, ausgeprägter ist als bei Wirtschaftspädagogikstudierenden, die eine Tätigkeit außerhalb des Schuldienstes anstreben bzw. noch unentschlossen sind. Letztlich kann aufgezeigt werden, dass grundsätzlich positive Zusammenhänge zwischen dem anfänglich ausgeprägten Berufsethos und der Berufswahlmotivation von angehenden Wirtschaftspädagog*innen bestehen.","lang":"ger"}],"ddc":["370"],"user_id":"30984","language":[{"iso":"ger"}],"date_updated":"2022-01-06T06:55:15Z","oa":"1","department":[{"_id":"452"}],"publication_identifier":{"issn":["1618-8543"]},"publication_status":"published","title":"Zum Zusammenhang von Berufsethos und der Berufswahlmotivation angehender Wirtschaftspädagog*innen"},{"status":"public","date_created":"2021-04-28T18:07:56Z","publication_status":"published","publication_identifier":{"issn":["1099-4300"]},"author":[{"orcid":"0000-0003-2444-7889","full_name":"Nüske, Feliks","first_name":"Feliks","id":"81513","last_name":"Nüske"},{"full_name":"Koltai, Péter","first_name":"Péter","last_name":"Koltai"},{"last_name":"Boninsegna","first_name":"Lorenzo","full_name":"Boninsegna, Lorenzo"},{"last_name":"Clementi","first_name":"Cecilia","full_name":"Clementi, Cecilia"}],"publication":"Entropy","department":[{"_id":"101"}],"user_id":"81513","title":"Spectral Properties of Effective Dynamics from Conditional Expectations","abstract":[{"text":"The reduction of high-dimensional systems to effective models on a smaller set of variables is an essential task in many areas of science.

We prove a new relative error bound in terms of the eigenfunction approximation error for reversible systems. We also present numerical examples indicating that, if Kramers–Moyal (KM) type approximations are used to compute the spectrum of the reduced generator, it seems largely insensitive to the time window used for the KM estimators.

This task can be understood as the inverse problem of multiobjective optimization, where the goal is to find the objective function vector of a given Pareto set. To this end, we present a method to construct the objective function vector of an unconstrained multiobjective optimization problem (MOP) such that the Pareto critical set contains a given set of data points with prescribed KKT multipliers. If such an MOP can not be found, then the method instead produces an MOP whose Pareto critical set is at least close to the data points. The key idea is to consider the objective function vector in the multiobjective KKT conditions as variable and then search for the objectives that minimize the Euclidean norm of the resulting system of equations. By expressing the objectives in a finite-dimensional basis, we transform this problem into a homogeneous, linear system of equations that can be solved efficiently. Potential applications of this approach include the identification of objectives (both from clean and noisy data) and the construction of surrogate models for expensive MOPs.","lang":"eng"}],"user_id":"47427","main_file_link":[{"url":"https://link.springer.com/content/pdf/10.1007/s10898-020-00983-z.pdf","open_access":"1"}],"citation":{"ieee":"B.

Recently, it was shown that TPhCs based on weak topology with a dislocation inherit this robustness and further host topologically protected lower-dimensional localized modes. However, TPhCs with weak topology at optical frequencies have not been demonstrated so far. Here, we use scattering-type scanning near-field optical microscopy to verify mid-bandgap zero-dimensional light localization close to 100 THz in a TPhC with nontrivial Zak phase and an edge dislocation. We show that because of the weak topology, differently extended dislocation centers induce similarly strong light localization. The experimental results are supported by full-field simulations. Along with the underlying fundamental physics, our results lay a foundation for the application of TPhCs based on weak topology in active topological nanophotonics, and nonlinear and quantum optic integrated devices because of their strong and robust light localization.","lang":"eng"}],"article_type":"original","user_id":"30525","ddc":["530"],"file":[{"file_name":"2021_ScienceAdv_TopologicalMode_Manuscript_Arxiv.pdf","date_created":"2022-03-03T07:24:44Z","access_level":"closed","creator":"zentgraf","file_id":"30197","file_size":2609760,"relation":"main_file","success":1,"date_updated":"2022-03-03T07:24:44Z","content_type":"application/pdf"}],"file_date_updated":"2022-03-03T07:24:44Z","publication":"Science Advances","author":[{"last_name":"Lu","first_name":"Jinlong","full_name":"Lu, Jinlong"},{"last_name":"Wirth","full_name":"Wirth, Konstantin G.","first_name":"Konstantin G."},{"full_name":"Gao, Wenlong","first_name":"Wenlong","last_name":"Gao"},{"first_name":"Andreas","full_name":"Heßler, Andreas","last_name":"Heßler"},{"first_name":"Basudeb","full_name":"Sain, Basudeb","last_name":"Sain"},{"last_name":"Taubner","first_name":"Thomas","full_name":"Taubner, Thomas"},{"last_name":"Zentgraf","id":"30525","first_name":"Thomas","orcid":"0000-0002-8662-1101","full_name":"Zentgraf, Thomas"}],"quality_controlled":"1","date_created":"2021-12-02T19:40:56Z","status":"public","has_accepted_license":"1","volume":7},{"language":[{"iso":"eng"}],"citation":{"chicago":"Schubert, Philipp, Ben Hermann, and Eric Bodden. “Lossless, Persisted Summarization of Static Callgraph, Points-To and Data-Flow Analysis.” In European Conference on Object-Oriented Programming (ECOOP), 2021.","ama":"Schubert P, Hermann B, Bodden E.

Whole-program analysis (WPA) can yield high precision, however causes long analysistimes and thus does not match common software-development workflows, making it often impracticalto use for large, real-world applications.This paper thus presents the design and implementation ofModAlyzer, a novel static-analysisapproach that aims at accelerating whole-program analysis by making the analysis modular andcompositional. It shows how to computelossless, persisted summaries for callgraph, points-to anddata-flow information, and it reports under which circumstances this function-level compositionalanalysis outperforms WPA.We implementedModAlyzeras an extension to LLVM and PhASAR, and applied it to 12 real-world C and C++ applications. At analysis time,ModAlyzermodularly and losslessly summarizesthe analysis effect of the library code those applications share, hence avoiding its repeated re-analysis.The experimental results show that the reuse of these summaries can save, on average, 72% ofanalysis time over WPA. Moreover, because it is lossless, the module-wise analysis fully retainsprecision and recall. Surprisingly, as our results show, it sometimes even yields precision superior toWPA. The initial summary generation, on average, takes about 3.67 times as long as WPA."}]},{"title":"Further development of a numerical method for analyzing the load capacity of clinched joints in versatile process chains","user_id":"34782","place":"ESAFORM 2021","publication_status":"submitted","date_created":"2020-12-21T08:15:27Z","project":[{"_id":"130","grant_number":"418701707","name":"TRR 285: TRR 285"},{"name":"TRR 285 - A: TRR 285 - Project Area A","_id":"131"},{"_id":"135","name":"TRR 285 – A01: TRR 285 - Subproject A01"}],"status":"public","department":[{"_id":"157"}],"author":[{"id":"34782","last_name":"Bielak","full_name":"Bielak, Christian Roman","first_name":"Christian Roman"},{"last_name":"Böhnke","id":"45779","first_name":"Max","full_name":"Böhnke, Max"},{"first_name":"Mathias","full_name":"Bobbert, Mathias","last_name":"Bobbert","id":"7850"},{"id":"32056","last_name":"Meschut","orcid":"0000-0002-2763-1246","full_name":"Meschut, Gerson","first_name":"Gerson"}],"doi":"10.25518/esaform21.4298","oa":"1","conference":{"end_date":"2021 04 16","location":"Lüttich","name":"ESAFORM 2021","start_date":"2021 04 14"},"_id":"20807","date_updated":"2022-03-29T12:55:57Z","citation":{"bibtex":"@inproceedings{Bielak_Böhnke_Bobbert_Meschut, place={ESAFORM 2021}, title={Further development of a numerical method for analyzing the load capacity of clinched joints in versatile process chains}, DOI={10.25518/esaform21.4298}, author={Bielak, Christian Roman and Böhnke, Max and Bobbert, Mathias and Meschut, Gerson} }","mla":"Bielak, Christian Roman, et al.

It is defined in stark contrast to total citation impact, a measure predominantly used in research evaluation that assumes that all citations are equal. Understanding ideational impact is critical for evaluating research impact and understanding how scientific disciplines build a cumulative tradition. Research has only recently developed automated citation classification techniques to distinguish between different types of citations and generally does not emphasize the conceptual content of the citations and its ideational impact. To address this problem, we develop Deep Content-enriched Ideational Impact Classification (Deep-CENIC) as the first automated approach for ideational impact classification to support researchers' literature search practices. We evaluate Deep-CENIC on 1,256 papers citing 24 information systems review articles from the IT business value domain. We show that Deep-CENIC significantly outperforms state-of-the-art benchmark models. We contribute to information systems research by operationalizing the concept of ideational impact, designing a recommender system for academic papers based on deep learning techniques, and empirically exploring the ideational impact of the IT business value domain.\r\n","lang":"eng"}],"ddc":["000"],"user_id":"72850","publication":"Decision Support Systems","keyword":["Ideational impact","citation classification","academic recommender systems","natural language processing","deep learning","cumulative tradition"],"file_date_updated":"2020-10-27T13:31:01Z","author":[{"last_name":"Prester","full_name":"Prester, Julian","first_name":"Julian"},{"first_name":"Gerit","full_name":"Wagner, Gerit","last_name":"Wagner"},{"first_name":"Guido","full_name":"Schryen, Guido","last_name":"Schryen","id":"72850"},{"first_name":"Nik Rushdi","full_name":"Hassan, Nik Rushdi","last_name":"Hassan"}],"file":[{"file_name":"DECSUP-D-20-00312 - PREPUBLICATION.pdf","date_created":"2020-10-27T13:31:01Z","access_level":"open_access","file_size":440903,"file_id":"20213","creator":"hsiemes","content_type":"application/pdf","date_updated":"2020-10-27T13:31:01Z","relation":"main_file"}],"volume":140,"date_created":"2020-10-27T13:28:21Z","status":"public","has_accepted_license":"1","date_updated":"2022-06-10T06:55:32Z","oa":"1","language":[{"iso":"eng"}],"title":"Classifying the Ideational Impact of Information Systems Review Articles: A Content-Enriched Deep Learning Approach","department":[{"_id":"277"}]},{"department":[{"_id":"277"}],"title":"Which Factors Affect the Scientific Impact of Review Papers in IS Research?

Insbesondere wenn das zugrunde liegende System von einem Parameter abhängt, ist es entscheidend, sie im Bezug auf diesen Parameter effizient zu verfolgen. Für die Berechnung invarianter Mengen stützen wir uns für ihre Approximation auf numerische Algorithmen. Typischerweise können diese Methoden jedoch nur auf endlich-dimensionale dynamische Systeme angewendet werden. In dieser Arbeit präsentieren wir daher einen numerischen Rahmen für die globale dynamische Analyse unendlich-dimensionaler Systeme. Wir werden Einbettungstechniken verwenden, um das core dynamical system (CDS) zu definieren, welches ein dynamisch äquivalentes endlich-dimensionales System ist.Das CDS wird dann verwendet, um eingebettete invariante Mengen, also eins-zu-eins Bilder, mittels Mengen-orientierten numerischen Methoden zu approximieren. Bei der Konstruktion des CDS ist es entscheidend, eine geeignete Beobachtungsabbildung auszuwählen und die geeignete inverse Abbildung zu entwerfen. Dazu werden wir geeignete numerische Implementierungen des CDS für DDEs und PDEs vorstellen. Für eine nachfolgende geometrische Analyse der eingebetteten invarianten Menge betrachten wir eine Lerntechnik namens diffusion maps, die ihre intrinsische Geometrie enthüllt sowie ihre Dimension schätzt. Schließlich wenden wir unsere entwickelten numerischen Methoden an einigen bekannten unendlich-dimensionale dynamischen Systeme an, wie die Mackey-Glass-Gleichung, die Kuramoto-Sivashinsky-Gleichung und die Navier-Stokes-Gleichung."},{"lang":"eng","text":"One central aspect in the study of dynamical systems is the analysis of its invariant sets such as the global attractor and (un)stable manifolds. In particular, when the underlying system depends on a parameter it is crucial to efficiently track those set with respect to this parameter. For the computation of invariant sets we rely on numerical algorithms for their approximation but typically those tools can only be applied to finite-dimensional dynamical systems. Thus, in thesis we present a numerical framework for the global dynamical analysis of infinite-dimensional systems. We will use embedding techniques for the definition of the core dynamical system (CDS) which is a dynamically equivalent finite-dimensional system. The CDS is then used for the approximation of related embedded invariant sets, i.e, one-to-one images, by set-oriented numerical methods. For the construction of the CDS it is crucial to choose an appropriate observation map and to design its corresponding inverse. Therefore, we will present suitable numerical realizations of the CDS for DDEs and PDEs. For a subsequent geometric analysis of the embedded invariant set we will consider a manifold learning technique called diffusion maps which reveals its intrinsic geometry and estimates its dimension. Finally, we apply our develop numerical tools on some well-known infinite-dimensional dynamical systems such as the Mackey-Glass equation, the Kuramoto-Sivashinsky equation and the Navier-Stokes equation."}],"user_id":"32643","title":"The Computation and Analysis of Invariant Sets of Infinite-Dimensional Systems"},{"place":"Bielefeld","title":"Einblicke in explizite und implizite Erwartungen Lehrender an Studierendentexte.

Systematic and holistic change impact analysis and proactive measures are required for reducing the number of requirement changes and their negative impact. There is no method to analyse the holistic impact of a requirement change in the context of developing complex technical systems. Holistic analysis requires to consider the local effects of requirement changes as well as effects from change propagation. To develop an approach for holistic change propagation and impact analysis, twelve performance goals are defined. Those are derived from a state of research analysis as well as an industry workshop. A three-step method is proposed. Firstly, requirement dependencies that cause change propagation are detected. Secondly, critical requirements are automatically identified based on a Page Rank algorithm. Thirdly, change impact of critical requirements is analysed based on a guideline. Validation proves that ten goals are fulfilled and two are partly fulfilled. The method addresses major shortcomings of preceding research and enables sound decision making for development engineers both before a change occurs and during decision process on a change request. This helps to reduce negative change impact in development projects and the risk of project failure."}]},{"main_file_link":[{"url":"https://eprint.iacr.org/2021/961","open_access":"1"}],"type":"preprint","year":"2021","citation":{"mla":"Bobolz, Jan, et al.

Reflectance and transmittance can be easily configured by selecting the trench width. At sufficiently high angles of incidence, the devices are lossless, apart from material attenuation and scattering due to surface roughness. We numerically simulate a series of devices within the full 0-to-1-range of splitting ratios, for semi-guided plane wave incidence as well as for excitation by focused Gaussian wave bundles. Straightforward cascading of the trenches leads to concepts for 1×M-power dividers and a polarization beam splitter."}],"user_id":"477","ddc":["530"],"file":[{"date_created":"2021-11-30T20:07:53Z","file_name":"2021-11 Hammer - OSA Continuum - Trenches.pdf","access_level":"open_access","file_id":"28197","creator":"fossie","file_size":6618403,"relation":"main_file","content_type":"application/pdf","date_updated":"2021-11-30T20:19:15Z"}],"file_date_updated":"2021-11-30T20:19:15Z","publication":"OSA Continuum","keyword":["tet_topic_waveguide"],"author":[{"last_name":"Hammer","id":"48077","first_name":"Manfred","full_name":"Hammer, Manfred","orcid":"0000-0002-6331-9348"},{"full_name":"Ebers, Lena","first_name":"Lena","id":"40428","last_name":"Ebers"},{"full_name":"Förstner, Jens","orcid":"0000-0001-7059-9862","first_name":"Jens","id":"158","last_name":"Förstner"}],"date_created":"2021-11-30T20:04:57Z","status":"public","has_accepted_license":"1","volume":4,"intvolume":" 4","_id":"28196","issue":"12","page":"3081","citation":{"short":"M.
