Alpine aquifers play a critical role in the hydrology of mountainous areas by sustaining base flow in downstream rivers during dry periods and retarding flood propagation after heavy precipitation events. Progressing climate change alters climatic and meteorological...
This book deals with the prediction of possible future scenarios concerning the COVID-19 pandemic. Based on the well-known SIR model by Kermack and McKendrick a compartment model is established.This model comprises its own assumptions, transition rates and transmission...
Epistemological beliefs—i.e. beliefs on the nature of knowledge, its limits, sources, and justification—play an important role both in everyday life and in learning processes. This book comprises several studies dealing with such beliefs in the domain of mathematics;...
Anja Schedel analyzes two models in the field of algorithmic game theory which both constitute bilevel problems in networks. The first model is a game-theoretic variant of the well-known Steiner forest problem, and one is interested in an optimal sharing of the cost of...
Considering the relevance of teachers‘ diagnostic competence for understanding students’ thinking and providing effective learning opportunities, Macarena Larrain investigates the development of future primary school teachers’ diagnostic competence in error situations...
This book provides a detailed overview of the microorganisms that form the initial growth on the exterior façades of buildings. It deals with the ecophysiological properties that characterize the basic conditions under which these microorganisms can occur on façades. In...
Technology is becoming more and more integrated in mathematics teaching and the use of technology is explicitly demanded by the curricula.Technology can be for example integrated while conceptualizing parameters of quadratic functions. In this thesis three technical...
In this book, Cathleen Heil addresses the question of how to conceptually understand children’s spatial thought in the context of geometry education. She proposes that in order to help children develop their abilities to successfully grasp and manipulate the spatial...
The number of women entrepreneurs is growing rapidly worldwide, however, women are still less likely than men to start a new business. Two factors influencing this are barriers and drivers, however, the understanding of how their interaction affects women’s...
Current corporate structures based on internationalisation and decentralisation are opposed to the nature of the most important resource: knowledge. The acquisition and exchange of (tacit) knowledge relies on interpersonal interactions and is thus time- and...
Oleg Wilfer presents a new conjugate duality concept for geometric and cone constrained optimization problems whose objective functions are a composition of finitely many functions. As an application, the author derives results for single minmax location problems...
Tobias Aberle examines how an entrepreneurship training helps disadvantaged youths in rural parts of Bihar, India, to cope with structural conditions that enable or constrain them. The present research reveals that young entrepreneurs can be divided into two groups:...
This volume, which is the output of a DAAD-funded collaboration between the University of Siegen and the Hanoi National University of Education, discusses and summarizes theoretical foundations of common grounds of mathematics and physics education.This...
The use of Likert scale instruments for measuring teachers’ beliefs is criticized because of amplifying social desirability, reducing the willingness to make differentiations, and often providing less or no contexts. Those weaknesses may distort teachers’ responses to a...
Christian Knittl-Frank reports on the development of a novel synthetic route to the naturally occurring polyhydroxylated oleanane, hederagonic acid. Polyhydroxylated oleananes are a vast family of naturally occurring triterpenoids with versatile biological activities. A...
a-Amino carbonyl compounds are omnipresent in all living organisms, making their selective synthesis highly sought after. However, the synthesis of a-amino amides, a subclass of a-amino carbonyls, in the presence of other carbonyls is usually challenging, due to the...
Support vector machines (SVMs) are one of the most successful algorithms on small and medium-sized data sets, but on large-scale data sets their training and predictions become computationally infeasible. The author considers a spatially defined data chunking method for...
Terrestrial hermit crabs are among the most widespread beach-dwelling organisms with key ecological functions but receive only very limited research attention. Sebastian Steibl demonstrates how physical parameters shape their overall distribution, presents a possible...
Stefan Rocktäschel introduces a branch-and-bound algorithm that determines a cover of the efficient set of multiobjective mixed-integer convex optimization problems. He examines particular steps of this algorithm in detail and enhances the basic algorithm with...
In this book, Paulo Guilherme Santos studies diagonalization in formal mathematics from logical aspects to everyday mathematics. He starts with a study of the diagonalization lemma and its relation to the strong diagonalization lemma. After that, Yablo’s paradox is...
