Various types of background knowledge about overlapping notes and text, clefs, graphical connections (neumes) and their implications on the position in staff of the notes were used and evaluated. Moreover, the effect of different encoder/decoder architectures and of different datasets for training a mixed model and for document-specific fine-tuning based on an extended OMR pipeline with an additional post-processing step were evaluated. The use of background models improves all metrics and in particular the melody accuracy rate (mAR), which is based on the insert, delete and replace operations necessary to convert the generated melody into the correct melody. When using a mixed model and evaluating on a different dataset, our best model achieves without fine-tuning and without post-processing a mAR of 90.4\%, which is raised by nearly 30\% to 93.2\% mAR using background knowledge. With additional fine-tuning, the contribution of post-processing is even greater: the basic mAR of 90.5\% is raised by more than 50\% to 95.8\% mAR.}, language = {en} } @article{GeyerHaanLorenzetal.2022, author = {Geyer, Johannes and Haan, Peter and Lorenz, Svenja and Zwick, Thomas and Bruns, Mona}, title = {Role of labor demand in the labor market effects of a pension reform}, series = {Industrial Relations}, volume = {61}, journal = {Industrial Relations}, number = {2}, doi = {10.1111/irel.12293}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-259446}, pages = {152-192}, year = {2022}, abstract = {This paper shows that labor demand plays an important role in the labor market reactions to a pension reform in Germany.

These employers offer their older employees partial retirement instead of forcing them into unemployment before early retirement because the older employees incur low substitution costs and high dismissal costs.}, language = {en} } @article{SonnenbergBannert2016, author = {Sonnenberg, Christoph and Bannert, Maria}, title = {Evaluating the Impact of Instructional Support Using Data Mining and Process Mining: A Micro-Level Analysis of the Effectiveness of Metacognitive Prompts}, series = {Journal of Educational Data Mining}, volume = {8}, journal = {Journal of Educational Data Mining}, number = {2}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-152375}, pages = {51-83}, year = {2016}, abstract = {In computer-supported learning environments, the deployment of self-regulatory skills represents an essential prerequisite for successful learning. Metacognitive prompts are a promising type of instructional support to activate students' strategic learning activities. However, despite positive effects in previous studies, there are still a large number of students who do not benefit from provided support. Therefore, it may be necessary to consider explicitly the conditions under which a prompt is beneficial for a student, i.e., so-called adaptive scaffolding. The current study aims to (i) classify the effectiveness of prompts on regulatory behavior, (ii) investigate the correspondence of the classification with learning outcome, and (iii) discover the conditions under which prompts induce regulatory activities (i.e., the proper temporal positioning of prompts). The think-aloud data of an experiment in which metacognitive prompts supported the experimental group (n = 35) was used to distinguish between effective and non-effective prompts. Students' activities preceding the prompt presentation were analyzed using data mining and process mining techniques. The results indicate that approximately half of the presented prompts induced metacognitive learning activities as expected. Moreover, the number of induced monitoring activities correlates positively with transfer performance. Finally, the occurrence of orientation and monitoring activities, which are not well-embedded in the course of learning, increases the effectiveness of a presented prompt. In general, our findings demonstrate the benefits of investigating metacognitive support using process data, which can provide implications for the design of effective instructional support.}, language = {en} } @article{SommerKloseWelschetal.2020, author = {Sommer, Claudia and Klose, Petra and Welsch, Patrick and Petzke, Frank and H{\"a}user, Winfried}, title = {Opioids for chronic non-cancer neuropathic pain.

Databases and Data Treatment Clinicaltrials.gov, CENTRAL, PubMed and PsycINFO were searched from October 2013 to June 2019. Randomized controlled trials comparing opioids with placebo and at least 4 weeks double-blinded duration were analysed. Primary outcomes were pain relief of 50\% or greater, disability, tolerability and safety. Effects were summarized by a random effects model using risk differences (RD) or standardized mean differences (SMD). We added four new studies with 662 participants for a total of 16 included studies with 2,199 participants. Study duration ranged between 4 and 12 weeks. Studies with a parallel and cross-over design: Based on low to moderate quality evidence, opioids (buprenorphine, hydromorphone, morphine, oxycodone, tramadol) provided a clinically relevant pain relief of 50\% or greater and reduction of disability compared to placebo. There was no clinically relevant harm with regards to the drop out rate due to adverse and serious adverse events by opioids compared to placebo. Enriched enrolment randomized withdrawal design: Based on low to moderate quality evidence, tapentadol provided a clinically relevant pain relief of 50\% or greater and reduction of disability compared to placebo in diabetic polyneuropathy. There was no clinically relevant harm with regards to the drop out rate due to adverse and serious adverse events by tapentadol compared to placebo. Conclusions Some opioids provided a short-term substantial pain relief in highly selected patients in some neuropathic pain syndromes. Significance Some opioids (buprenorphine, morphine, oxycodone, tramadol, tapentadol) provide substantial pain relief compared to placebo in postherpetic neuralgia and peripheral neuropathies of different aetiologies for 4-12 weeks. There is insufficient evidence to support or refute the suggestion that these drugs are effective in other neuropathic pain conditions. The safety of opioids with regards to abuse and deaths in the studies analysed cannot be extrapolated to routine clinical care.}, language = {en} } @article{DuMaYanez‐Serranoetal.2021, author = {Du, Baoguo and Ma, Yuhua and Y{\´a}{\~n}ez-Serrano, Ana Maria and Arab, Leila and Fasbender, Lukas and Alfarraj, Saleh and Albasher, Gadah and Hedrich, Rainer and White, Philip J. and Werner, Christiane and Rennenberg, Heinz}, title = {Physiological responses of date palm (Phoenix dactylifera) seedlings to seawater and flooding}, series = {New Phytologist}, volume = {229}, journal = {New Phytologist}, number = {6}, doi = {10.1111/nph.17123}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-228226}, pages = {3318 -- 3329}, year = {2021}, abstract = {In their natural environment along coast lines, date palms are exposed to seawater inundation and, hence, combined stress by salinity and flooding. To elucidate the consequences of this combined stress on foliar gas exchange and metabolite abundances in leaves and roots, date palm seedlings were exposed to flooding with seawater and its major constituents under controlled conditions. Seawater flooding significantly reduced CO\(_{2}\) assimilation, transpiration and stomatal conductance, but did not affect isoprene emission. A similar effect was observed upon NaCl exposure. By contrast, flooding with distilled water or MgSO\(_{4}\) did not affect CO\(_{2}\)/H\(_{2}\)O gas exchange or stomatal conductance significantly, indicating that neither flooding itself, nor seawater sulfate, contributed greatly to stomatal closure. Seawater exposure increased Na and Cl contents in leaves and roots, but did not affect sulfate contents significantly. Metabolite analyses revealed reduced abundances of foliar compatible solutes, such as sugars and sugar alcohols, whereas nitrogen compounds accumulated in roots. Reduced transpiration upon seawater exposure may contribute to controlling the movement of toxic ions to leaves and, therefore, can be seen as a mechanism to cope with salinity. The present results indicate that date palm seedlings are tolerant towards seawater exposure to some extent, and highly tolerant to flooding.}, language = {en} } @article{AtiyasDoganogluInceoglu2021, author = {Atiyas, Izak and Doganoglu, Toker and Inceoglu, Firat}, title = {Upstream Competition with Complex and Unobservable Contracts}, series = {Review of Industrial Organization}, volume = {58}, journal = {Review of Industrial Organization}, doi = {10.1007/s11151-020-09766-y}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-241161}, pages = {399-429}, year = {2021}, abstract = {This paper examines situations where two vertically integrated firms consider supplying an input to an independent downstream competitor via privately observed contracts. We identify equilibria where competition in the upstream market emerges—the downstream competitor gets supplied—as well as when the downstream firm does not receive the input and is excluded from the market. The likelihood of the outcome in which the downstream firm does not get supplied depends not only on demand parameters, but also on contractual flexibility and observability. We show that when contracts are unobservable, downstream entry will occur less often. Furthermore, our results suggest that permitting contracts that enable the contracting parties to coordinate their behavior in the downstream market may improve welfare by increasing the likelihood that the downstream firm is supplied.}, language = {en} } @incollection{Bergengruen2020, author = {Bergengruen, Maximilian}, title = {Der ‚Herr der Finsternis' und der Geist des Lichts.

Existing datasets are often limited to a small number of study sites, few points in time, a narrow range of land-use intensities and only some taxonomic groups, or they lack standardised sampling. While new monitoring programs have been initiated, they still cover rather short time periods. Daskalova et al. 2021 (Insect Conservation and Diversity, 14, 1-18) argue that temporal trends of insect populations derived from short time series are biased towards extreme trends, while their own analysis of an assembly of shorter- and longer-term time series does not support an overall insect decline. With respect to the results of Seibold et al. 2019 (Nature, 574, 671-674) based on a 10-year multi-site time series, they claim that the analysis suffers from not accounting for temporal pseudoreplication. Here, we explain why the criticism of missing statistical rigour in the analysis of Seibold et al. (2019) is not warranted. Models that include 'year' as random effect, as suggested by Daskalova et al. (2021), fail to detect non-linear trends and assume that consecutive years are independent samples which is questionable for insect time-series data. We agree with Daskalova et al. (2021) that the assembly and analysis of larger datasets is urgently needed, but it will take time until such datasets are available. Thus, short-term datasets are highly valuable, should be extended and analysed continually to provide a more detailed understanding of insect population changes under the influence of global change, and to trigger immediate conservation actions.}, language = {en} } @article{PalaciosEspinoza2019, author = {Palacios Espinoza, Romina Irene}, title = {Schmerzhafte Erotik: kranke K{\"o}rper und sexueller Genuss in El {\´u}ltimo cuerpo de {\´U}rsula von Patricia de Souza}, series = {promptus - W{\"u}rzburger Beitr{\"a}ge zur Romanistik}, volume = {5}, journal = {promptus - W{\"u}rzburger Beitr{\"a}ge zur Romanistik}, issn = {2364-6705}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-221877}, pages = {117-132}, year = {2019}, abstract = {This article is dedicated to the analysis of the body, which is staged as sick and painful.
