Most studies assume that agents have an accurate perception regarding their tax burden. However, there is a growing body of literature analyzing whether taxes are indeed perceived correctly. We review 128 studies on the measurement of tax misperception and its behavioral implications. The review reveals that many taxpayers have substantial tax misperceptions that lead to biased decision making. We develop a Behavioral Taxpayer Response Model on the impact of provided tax information on tax perception. Besides individual traits, characteristics of the tax information and the decision environment determine the extent of tax misperception. We discuss opportunities for future research and methodological limitations. While there is much evidence on tax misperception at the individual level, we hardly find any research at the firm level. Little is known about the real effects of managers’ tax misperception and on how tax information is strategically managed to impact stakeholders. This research gap is surprising as a large part of the accounting literature analyzes decision making and disclosure of firms. We recommend a mixed-method approach combining experiments, surveys, and archival data analyses to improve the knowledge on tax misperception and its consequences.","lang":"eng"}],"language":[{"iso":"eng"}],"quality_controlled":"1","issue":"1","year":"2022","date_created":"2021-03-09T08:07:40Z","title":"Tax Misperception and Its Effects on Decision Making - Literature Review and Behavioral Taxpayer Response Model","type":"journal_article","status":"public","_id":"21405","department":[{"_id":"187"}],"user_id":"530","article_type":"original","publication_status":"published","related_material":{"link":[{"url":"https://www.tandfonline.com/doi/suppl/10.1080/09638180.2020.1852095/suppl_file/rear_a_1852095_sm0954.pdf","relation":"supplementary_material"}]},"intvolume":"        31","page":"111-144","citation":{"apa":"Blaufus, K., Chirvi, M., Huber, H.-P., Maiterth, R., &#38; Sureth-Sloane, C.

However, methods and techniques for the monetary valuation of brands are still under-researched. Hence, the objective of this study is to evaluate the utility of explanatory statistical models and machine learning approaches for explaining and predicting brand value. Drawing upon the case of the most valuable English football brands during the 2016/17 to 2020/21 seasons, we demonstrate how to operationalize Aaker's (1991) theoretical brand equity framework to collect meaningful qualitative and quantitative feature sets. Our explanatory models can explain up to 77% of the variation in brand valuations across all clubs and seasons, while our predictive approach can predict out-of-sample observations with a mean absolute percentage error (MAPE) of 14%. Future research can build upon our results to develop domain-specific brand valuation methods while enabling managers to make better-informed investment decisions."}],"publication":"Proceeding of the 28th Americas Conference on Information Systems (AMCIS)","type":"conference","language":[{"iso":"eng"}],"department":[{"_id":"195"}],"user_id":"60721","_id":"41486","citation":{"bibtex":"@inproceedings{Caron_Bartelheimer_Müller_2022, place={Minneapolis, USA}, title={Towards a Reliable &#38; Transparent Approach to Data-Driven Brand Valuation}, booktitle={Proceeding of the 28th Americas Conference on Information Systems (AMCIS)}, author={Caron, Matthew and Bartelheimer, Christian and Müller, Oliver}, year={2022} }","short":"M.

The former allows one to classify problems more\r\nfinely than the Polynomial-Time Hierarchy (PH), whereas the latter\r\ncharacterizes physically motivated problems such as Approximate Simulation\r\n(APX-SIM) [Ambainis, CCC 2014]. In this area, a central role has been played by\r\nthe classes $P^{NP[\\log]}$ and $P^{QMA[\\log]}$, defined identically to $P^{NP}$\r\nand $P^{QMA}$, except that only logarithmically many oracle queries are\r\nallowed. Here, [Gottlob, FOCS 1993] showed that if the adaptive queries made by\r\na $P^{NP}$ machine have a \"query graph\" which is a tree, then this computation\r\ncan be simulated in $P^{NP[\\log]}$.\r\n  In this work, we first show that for any verification class\r\n$C\\in\\{NP,MA,QCMA,QMA,QMA(2),NEXP,QMA_{\\exp}\\}$, any $P^C$ machine with a query\r\ngraph of \"separator number\" $s$ can be simulated using deterministic time\r\n$\\exp(s\\log n)$ and $s\\log n$ queries to a $C$-oracle. When $s\\in O(1)$ (which\r\nincludes the case of $O(1)$-treewidth, and thus also of trees), this gives an\r\nupper bound of $P^{C[\\log]}$, and when $s\\in O(\\log^k(n))$, this yields bound\r\n$QP^{C[\\log^{k+1}]}$ (QP meaning quasi-polynomial time). We next show how to\r\ncombine Gottlob's \"admissible-weighting function\" framework with the\r\n\"flag-qubit\" framework of [Watson, Bausch, Gharibian, 2020], obtaining a\r\nunified approach for embedding $P^C$ computations directly into APX-SIM\r\ninstances in a black-box fashion. Finally, we formalize a simple no-go\r\nstatement about polynomials (c.f. [Krentel, STOC 1986]): Given a multi-linear\r\npolynomial $p$ specified via an arithmetic circuit, if one can \"weakly\r\ncompress\" $p$ so that its optimal value requires $m$ bits to represent, then\r\n$P^{NP}$ can be decided with only $m$ queries to an NP-oracle.","lang":"eng"}],"department":[{"_id":"623"},{"_id":"7"}],"user_id":"71541","_id":"27160","language":[{"iso":"eng"}],"issue":"75","intvolume":"       215","page":"1-27","citation":{"chicago":"Gharibian, Sevag, and Dorian Rudolph. “On Polynomially Many Queries to NP or QMA Oracles.” In <i>13th Innovations in Theoretical Computer Science (ITCS 2022)</i>, 215:1–27, 2022. <a href=\"https://doi.org/10.4230/LIPIcs.ITCS.2022.75\">https://doi.org/10.4230/LIPIcs.ITCS.2022.75</a>.","ieee":"S.

Diese Arbeit befasst sich mit der numerischen Optimierung des axialdynamischen Schaltverhaltens von Federkraftbremsen auf Basis eines Multidomänenmodells. Das zu diesem Zweck entwickelte Multidomänenmodell berücksichtigt elektrische, magnetische, mechanische und thermische Effekte, die während des Betriebs kontinuierlich miteinander in Wechselwirkung stehen. Dazu werden zunächst topologiebasierte Teilmodelle der einzelnen Effekte entwickelt, die zu einem geschlossenen Multidomänen-Gesamtmodell verknüpft werden. Eine experimentelle Validierung weist die Gültigkeit des Multidomänenmodells nach. Für die Optimierung wird zunächst eine Optimierungsstruktur auf Basis des Multidomänenmodells entwickelt und implementiert. Im Rahmen zweier Anwendungsbeispiele wird die Funktionalität der Optimierungsstruktur nachgewiesen.","lang":"ger"}],"type":"dissertation"},{"publication":"Arno Schmidt Handbuch.

In the Pb-based metal-organic framework, in contrast, no extended hydrogen bonding occurs, as the sulfonate groups coordinate to Pb<jats:sup>2+</jats:sup>, without forming hydrogen bonds; the proton conductivity is much lower in this material.</jats:p>"}],"publication":"Beilstein Journal of Nanotechnology","keyword":["Electrical and Electronic Engineering","General Physics and Astronomy","General Materials Science"],"language":[{"iso":"eng"}],"year":"2022","quality_controlled":"1","title":"The role of sulfonate groups and hydrogen bonding in the proton conductivity of two coordination networks","publisher":"Beilstein Institut","date_created":"2023-01-10T09:12:54Z"},{"title":"Challenges in the interpretation of gas core levels for the determination of gas-solid interactions within dielectric porous films by ambient pressure XPS","doi":"10.1016/j.apsusc.2022.154525","date_updated":"2023-03-03T11:32:04Z","publisher":"Elsevier BV","author":[{"full_name":"de los Arcos, Teresa","last_name":"de los Arcos","first_name":"Teresa"},{"first_name":"Christian","id":"11848","full_name":"Weinberger, Christian","last_name":"Weinberger"},{"last_name":"Zysk","id":"14757","full_name":"Zysk, Frederik","first_name":"Frederik"},{"first_name":"Varun","full_name":"Raj Damerla, Varun","last_name":"Raj Damerla"},{"first_name":"Sabrina","last_name":"Kollmann","full_name":"Kollmann, Sabrina"},{"first_name":"Pascal","full_name":"Vieth, Pascal","last_name":"Vieth"},{"full_name":"Tiemann, Michael","id":"23547","last_name":"Tiemann","orcid":"0000-0003-1711-2722","first_name":"Michael"},{"first_name":"Thomas","last_name":"Kühne","id":"49079","full_name":"Kühne, Thomas"},{"full_name":"Grundmeier, Guido","id":"194","last_name":"Grundmeier","first_name":"Guido"}],"date_created":"2022-10-11T08:22:25Z","volume":604,"year":"2022","citation":{"apa":"de los Arcos, T., Weinberger, C., Zysk, F., Raj Damerla, V., Kollmann, S., Vieth, P., Tiemann, M., Kühne, T., &#38; Grundmeier, G.

The films were differentiated in terms of porosity and roughness. The XPS N1s core levels of the N2 gas in presence of the SiO2 samples showed variations in width, binding energy and line shape. The width correlated with the surface charge induced in the dielectric films upon X-ray irradiation. The observed different binding energies observed for the N1s peak can only partly be associated with intrinsic work function differences between the samples, opening the possibility that the effect of physisorption at room temperature could be detected by a shift in the measured binding energy. However, the signals also show an increasing asymmetry with rising surface charge. This might be associated with the formation of vertical electrical gradients within the dielectric porous thin films, which complicates the assignment of binding energy positions to specific surface-related effects. With the support of Monte Carlo and first principles density functional theory calculations, the observed shifts were discussed in terms of the possible formation of transitory dipoles upon N2 physisorption within the porous SiO2 films."}],"status":"public","type":"journal_article","publication":"Applied Surface Science"},{"publication":"Advanced Materials Interfaces","abstract":[{"lang":"eng","text":"In the spatial confinement of cylindrical mesopores with diameters of a few nanometers, water molecules experience restrictions in hydrogen bonding. This leads to a different behavior regarding the molecular orientational freedom (‘structure of water') compared to the bulk liquid state. In addition to the pore size, the behavior is also strongly affected by the strength of the pore wall-to-water interactions, that is, the pore wall polarity. In this work, this is studied both experimentally and theoretically. The surface polarity of mesoporous silica (SiO2) is modified by functionalization with trimethylsilyl moieties, resulting in a change from a hydrophilic (pristine) to a hydrophobic pore wall. The mesopore surface is characterized by N2 and H2O sorption experiments. Those results are combined with IR spectroscopy to investigate pore wall-to-water interactions leading to different structures of water in the mesopore. Furthermore, the water's structure is studied theoretically to gain deeper insight into the interfacial interactions. For this purpose, the structure of water is analyzed by pairing densities, coordination, and angular distributions with a novel adaptation of surface-specific sum-frequency generation calculation for pore environments."}],"language":[{"iso":"eng"}],"keyword":["Mechanical Engineering","Mechanics of Materials"],"issue":"20","quality_controlled":"1","year":"2022","date_created":"2022-10-11T08:17:57Z","publisher":"Wiley","title":"The Structure of Water in Silica Mesopores – Influence of the Pore Wall Polarity","type":"journal_article","status":"public","department":[{"_id":"613"},{"_id":"35"},{"_id":"2"},{"_id":"307"},{"_id":"304"}],"user_id":"23547","_id":"33685","article_number":"2200245","article_type":"original","publication_identifier":{"issn":["2196-7350","2196-7350"]},"publication_status":"published","intvolume":"         9","citation":{"apa":"Weinberger, C., Zysk, F., Hartmann, M., Kaliannan, N., Keil, W., Kühne, T., &#38; Tiemann, M.
