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...
Simon Greiner investigates the molecular-level stabilization of polyoxovanadate (POV) compounds by rational design for the application as active cathode material in lithium-ion batteries. Formation of a complex hydrogen-bonding network locks the POVs in place and...
The county diagnostic method is a spatially explicit, unit specific, component expanded regional environmental footprint framework for the USA designed by Bryce Lawrence to compare the influence of ecoregions on poly-factorial environmental footprints. This 'diagnostic...
Ole Martin extends well-established techniques for the analysis of high-frequency data based on regular observations to the more general setting of asynchronous and irregular observations. Such methods are much needed in practice as real data usually comes in irregular...
Danica Heller-Krippendorf develops concepts and approaches optimizing the applicability of MVA on data sets from an industrial context. They enable more time-efficient MVA of the respective ToF-SIMS data. Priority is given to two main aspects by the author: First, the...
Christoph Lohmann introduces a very general framework for the analysis and design of bound-preserving finite element methods. The results of his in-depth theoretical investigations lead to promising new extensions and modifications of existing algebraic flux correction...
This book is a practical, compact guide for the identification of common tropical and subtropical ornamental plants by flower colour. It is intended for anyone who is interested in plants and would like to get to know the attractive flowering plants of warm regions...
Christina Maria Tonauer finds novel evidence for the first-order nature of the transition between high-density amorphous ice (HDA) and low-density amorphous ice (LDA), supporting water’s liquid-liquid transition scenarios. Pressure-dependent crystallisation experiments...
