Personalizing real‐world problems by (1) matching problems to students' shared living environment (context personalization) and (2) asking students to pose their own problems (active personalization) might be two interventions to increase students' task motivation.AimIn the current study, we investigated the effects of context personalization and active personalization on students' self‐efficacy expectations, intrinsic value, attainment value, utility value, and cost.SampleThe participants were 28 fifth‐ and sixth‐grade students who voluntarily took part in a six‐month afterschool program in which they posed problems with the aim of creating a math walk in their hometown.MethodUsing a within‐subjects design, at the end of the afterschool program, the students rated their self‐efficacy expectations and task values for four self‐developed problems associated with their hometown, four peer‐developed problems associated with their hometown, and four instructor‐provided problems associated with unfamiliar locations.ResultsStudents reported higher self‐efficacy expectations, intrinsic value, attainment value, and utility value for active‐personalized than non‐personalized problems. To a lesser extent, context personalization promoted intrinsic value and attainment value. No effect was found for cost.ConclusionsActive personalization (i.e. asking students to pose their own real‐world problems) is suited to enhance students' task motivation, specifically their self‐efficacy expectations, intrinsic value, attainment value, and utility value. Context personalization still boosts students' intrinsic value and attainment value. Implementation in classroom instruction is discussed."}],"language":[{"iso":"eng"}],"citation":{"mla":"Schoenherr, Johanna. “Personalizing Real‐world Problems: Posing Own Problems Increases Self‐efficacy Expectations, Intrinsic Value, Attainment Value, and Utility Value.” British Journal of Educational Psychology, Wiley, 2024, doi:10.1111/bjep.12653.","bibtex":"@article{Schoenherr_2024, title={Personalizing real‐world problems: Posing own problems increases self‐efficacy expectations, intrinsic value, attainment value, and utility value}, DOI={10.1111/bjep.12653}, journal={British Journal of Educational Psychology}, publisher={Wiley}, author={Schoenherr, Johanna}, year={2024} }","apa":"Schoenherr, J.

In this work, we focus on two fundamental tasks from the study of\r\nBoolean satisfiability (SAT) problems: search-to-decision reductions, and\r\napproximate counting. We first show that, in strong contrast to the classical\r\nsetting where a poly-time Turing machine requires $\\Theta(n)$ queries to an NP\r\noracle to compute a witness to a given SAT formula, quantumly $\\Theta(\\log n)$\r\nqueries suffice. We then show this is tight in the black-box model - any\r\nquantum algorithm with \"NP-like\" query access to a formula requires\r\n$\\Omega(\\log n)$ queries to extract a solution with constant probability.\r\nMoving to approximate counting of SAT solutions, by exploiting a quantum link\r\nbetween search-to-decision reductions and approximate counting, we show that\r\nexisting classical approximate counting algorithms are likely optimal. First,\r\nwe give a lower bound in the \"NP-like\" black-box query setting: Approximate\r\ncounting requires $\\Omega(\\log n)$ queries, even on a quantum computer. We then\r\ngive a \"white-box\" lower bound (i.e. where the input formula is not hidden in\r\nthe oracle) - if there exists a randomized poly-time classical or quantum\r\nalgorithm for approximate counting making $o(log n)$ NP queries, then\r\n$\\text{BPP}^{\\text{NP}[o(n)]}$ contains a $\\text{P}^{\\text{NP}}$-complete\r\nproblem if the algorithm is classical and $\\text{FBQP}^{\\text{NP}[o(n)]}$\r\ncontains an $\\text{FP}^{\\text{NP}}$-complete problem if the algorithm is\r\nquantum.","lang":"eng"}],"user_id":"71541","title":"BQP, meet NP: Search-to-decision reductions and approximate counting"},{"citation":{"apa":"Ackermann, D.

Daher gibt es starke Bestrebungen in diesem Bereich hin zu einer höheren Wirtschaftlichkeit, welche beispielsweise durch höheren Massedurchsatz bei gleichbleibender Maschinengröße erreicht werden kann, oder aber auch im Hinblick auf eine Kreislaufwirtschaft die Bestrebung hin zu einer materialschonenden Verarbeitung. Beide Bestrebungen erfordern spezielle Schneckenkonzepte. Hierunter fallenWave- Schnecken, welche in beiden Bereichen ein vorteilhaftes Prozessverhalten aufzeigen sollen. Die Auslegung von Wave-Schnecken erfordert jedoch ein stärkeres Verständnis über das geometrieabhängige Prozessverhalten in der Extrusion. \r\nIm Rahmen der Dissertation werden zwei Themengebiete angegangen.

Das zweite Thema behandelt die Auslegung von Wave-Schnecken basierend auf numerischen Simulationen samt Validierung anhand von sieben Energy-Transfer-Schnecken im Vergleich zu drei konventionellen Schnecken. Hierbei werden unter anderem der Materialabbau, die thermische und die stoffliche Homogenität betrachtet, um ein umfassendes Bild über das Prozessverhalten der Schnecken zu schaffen.

For this reason, there are strong efforts in this area towards greater economic efficiency, which can be achieved, for example, through higher mass throughput with the same machine size, or, with regard to a circular economy, towards material-preserving processing. Both endeavours require special screw concepts. These include wave screws, which should demonstrate advantageous process behaviour in both areas. However, the design of wave screws requires a better understanding of the geometry-dependent process behaviour in extrusion. \r\nTwo topics are addressed in the dissertation. The first topic is the derivation of a method to characterise the degradation behaviour of thermoplastics and the use of the characterisation as a predictive model. The second topic deals with the design of wave screws based on numerical simulations including validation using seven energy transfer screws in comparison to three conventional screws. Among other things, the material degradation, the thermal and the material homogeneity are considered in order to create a comprehensive picture of the process behaviour of the screws. The presented investigations ultimately serve to confirm the advantageous process behaviour of wave screws.","lang":"eng"}],"user_id":"44224","series_title":"Schriftenreihe Kunststofftechnik Paderborn","language":[{"iso":"ger"}],"date_updated":"2024-01-16T09:49:07Z","department":[{"_id":"148"},{"_id":"321"},{"_id":"9"}],"publication_status":"published","publication_identifier":{"isbn":["978-3-8440-9334-6"]},"place":"Düren","title":"Materialschonende Verarbeitung von Thermoplasten auf Wave-Schnecken"},{"publication":"Berufs-und Fachsprache Deutsch in Wissenschaft und Praxis","publisher":"DE GRUYTER","author":[{"last_name":"Prediger","full_name":"Prediger, Susanne","first_name":"Susanne"},{"id":"85190","last_name":"Wessel","full_name":"Wessel, Lena","first_name":"Lena"}],"volume":"Band 3","date_created":"2024-01-17T10:58:04Z","status":"public","user_id":"37888","main_file_link":[{"open_access":"1","url":"https://www.degruyter.com/document/doi/10.1515/9783110745504/pdf?licenseType=restricted#page=381"}],"page":"363-372","type":"book_chapter","year":"2024","citation":{"chicago":"Prediger, Susanne, and Lena Wessel. “31 Sprachbildung im berufsbezogenen Mathematikunterricht.” In Berufs-und Fachsprache Deutsch in Wissenschaft und Praxis, edited by Christian Efing and Zeynep Kalkavan-Aydin, Band 3:363–72.

Unlike existing approaches, our anomaly indicator introduces three methodological novelties. First, we use an endogenous, purely data-driven, nonparametric trend identification method to separate long-term market movements from more short-term ones. Second, we apply SETAR models that allow for asymmetric expansions and contractions around the long-term trend and find systematic stock price cycles. Third, we implement these findings in our indicator and conduct real-time market forecasts, which have so far been neglected in the literature. Applications of our indicator using monthly S&P 500 stock data from 1970 to the end of 2022 show that short-term anomalous market movements can be identified in real time up to one year ahead. We predict all major anomalies, including the 1987 Bubble and the initial phase of the Financial Crisis that began in 2007. In total, our anomaly indicator identifies more than 80% of all – even minor – anomalous episodes. Thus, smoothing market exaggerations through early signaling seems possible.","lang":"eng"}],"article_type":"original","date_created":"2024-01-22T08:49:02Z","status":"public","keyword":["General Economics","Econometrics and Finance","Finance"],"publication":"Quantitative Finance","author":[{"last_name":"Fritz","full_name":"Fritz, Marlon","first_name":"Marlon"},{"full_name":"Gries, Thomas","first_name":"Thomas","id":"186","last_name":"Gries"},{"first_name":"Lukas","full_name":"Wiechers, Lukas","last_name":"Wiechers"}],"publisher":"Informa UK Limited","doi":"10.1080/14697688.2023.2281529","date_updated":"2024-01-22T08:54:05Z","language":[{"iso":"eng"}],"title":"An early indicator for anomalous stock market performance","publication_identifier":{"issn":["1469-7688","1469-7696"]},"publication_status":"published","department":[{"_id":"19"},{"_id":"200"},{"_id":"202"},{"_id":"475"}]},{"language":[{"iso":"eng"}],"type":"journal_article","citation":{"short":"K.S.
