In a recent paper [7] the author considered the family of parametrized Thue equations

Steganographie ist eine Technik zur vertraulichen Kommunikation. Ihre Sicherheit definiert sich über das Unvermögen des Angreifers, die Existenz einer vertraulichen Kommunikation nachzuweisen. Ziel dieses Beitrags ist es, einige Analysemuster für Schwachstellen am Beispiel einer veröffentlichten Spreizspektrummethode für Steganographie in Audiomedien (Nutzinger und Wurzer, ARES 2011) vorzustell...

Using a novel Wintner-type formulation of the classical Peano’s existence theorem [Math. Ann. 37 (1890), 182-228], we enhance Ważewski’s result on invertibility of maps defined on closed balls [Ann. Soc. Pol. Math. 20 (1947), 81-125] securing the size of the domain of invertibility that agrees with the bounds derived by John [Comm. Pure Appl. Math. 21 (1968), 77-110] and Sotomayor [Z. Angew. Ma...

Dieser Beitrag beschreibt eine Evaluation über einen Zeitraum von mehreren Jahren, die das Nutzungsverhalten, die Funktionalität und Usability von Vorlesungsaufzeichnungen aus der Sicht von Studierenden im Fach Informatik untersuchte. Die Ergebnisse der Auswertungen bestätigen bisherige Vermutungen über den Mehrwert von Vorlesungsaufzeichnungen, zeigen aber auch, welche Funktionalitäten bzw. Me...

Das Pilotprojekt „Virtuelles Softwareprojekt“ ermöglicht Osnabrücker Studierenden erstmals, hochschulübergreifend an der in Oldenburg durchgeführten Lehrveranstaltung „Softwareprojekt“ teilzunehmen. Neue Medien wie beispielsweise Videokonferenzsysteme werden eingesetzt, um die Veranstaltung über die reine Präsenzlehre hinaus durchführen zu können. Ein wesentliches Ziel des Projektes ist neben d...

Fluency with simple arithmetic, typically achieved in early elementary school, is thought to be one of the building blocks of mathematical competence. Behavioral studies with adults indicate that math anxiety (feelings of tension or apprehension about math) is associated with poor performance on cognitively demanding math problems. However, it remains unclear whether there are fundamental diffe...

The goal of this first major report from the Western Reserve Reading Project Math component is to explore the etiology of the relationship among tester-administered measures of mathematics ability, reading ability, and general cognitive ability. Data are available on 314 pairs of monozygotic and same-sex dizygotic twins analyzed across 5 waves of assessment. Univariate analyses provide a range ...

In response to calls to improve the quantitative training of undergraduate biology students, there have been increased efforts to better integrate math into biology curricula. One challenge of such efforts is negative student attitudes toward math, which are thought to be particularly prevalent among biology students. According to theory, students' personal values toward using math in a biologi...

In this paper, some recent results established by Marin Borcut [M. Borcut, Tripled fixed point theorems for monotone mappings in partially ordered metric spaces, Carpathian J. Math. 28, 2 (2012), 207--214] and [M. Borcut, Tripled coincidence theorems for monotone mappings in partially ordered metric spaces, Creat. Math. Inform. 21, 2 (2012), 135--142] are generalized and improved, with much sho...

Students rarely practice math outside of school requirements, which we refer to as the "math-practice gap". This gap might be the reason why students struggle with math, making it urgent to develop means by which to address it. In the current paper, we propose that math apps offer a viable solution to the math-practice gap: Online apps can provide access to a large number of problems, tied to i...
