In this PhD thesis the question “What makes firms innovative?” is evaluated. In particular, the thesis investigates the differential impact of inter-organizational social networks comprising various different corporate partners on the knowledge stock of a company, evaluates how and to what extent internal knowledge capabilities contribute to innovation success, and scrutinizes how both inter-organizational social networks and internal knowledge capabilities interact and thereby affect innovation success. Therefore, the thesis combines the social capital theory and the concept of absorptive capacity on an organizational level and applies survey data from the German manufacturing industry. Among others, the thesis shows that, first, innovativeness of external partners is contagious, second, that besides customers especially R&D partners can be valuable sources of different types of knowledge, and, third, how the usage of knowledge management systems fosters innovation success. Thereby the results contribute not only to the innovation literature and, in particular, to the open innovation literature, but also to the research fields of inter-organizational knowledge transfer, absorptive capacity, and social capital theory.
The challenge of realism is one of the common features of current philosophical debates, across different cultural traditions, and in many areas of investigation (epistemology, metaphysics, ethics, aesthetics, theory of action, etc.). The implications of realism for political philosophy and political practice, though, are just starting to become an object of systematic discussions. Such implications, however, are significant, since the area of politics is contiguous with that of ethics and action, for example. This volume intends to contribute to debates on the relevance of realism – especially moral realism – for politics. The essays included in the collection address a number of related issues, ranging from foundational problems of realism in ethics, action theory and politics, to questions about pragmatics, to difficulties in political theory, and to political hindrances related to economics and legal theory. The common focus of all essays is the relevance of realism for a conception of practical rationality in political contexts.
Description logics (DLs) represent a widely studied logical formalism with a significant impact in the field of knowledge representation and the Semantic Web. However, they are equipped with a classical descriptive semantics that is characterised by a platonic notion of truth, being insufficiently expressive to deal with evolving and incomplete information, as from data streams or ongoing processes. Such partially determined and incomplete knowledge can be expressed by relying on a constructive semantics. This thesis investigates the model and proof theory of a constructive variant of the basic description logic ALC, called cALC. The semantic dimension of constructive DLs is investigated by replacing the classical binary truth interpretation of ALC with a constructive notion of truth. This semantic characterisation is crucial to represent applications with partial information adequately, and to achieve both consistency under abstraction as well as robustness under refinement, and on the other hand is compatible with the Curry-Howard isomorphism in order to form the cornerstone for a DL-based type theory. The proof theory of cALC is investigated by giving a sound and complete Hilbert-style axiomatisation, a Gentzen-style sequent calculus and a labelled tableau calculus showing finite model property and decidability. Moreover, cALC can be strengthened towards normal intuitionistic modal logics and classical ALC in terms of sound and complete extensions and hereby forms a starting point for the systematic investigation of a constructive correspondence theory.
In this volume, we are publishing three centuries of Cyrillic and Glagolitic alphabet tables from Western sources. The illustrations presented here have been enhanced, cleaned up and digitally restored. Most of them have never been published in such a high quality before.
In times of an ever increasing amount of data and a growing diversity of data types in different application contexts, there is a strong need for large-scale and ﬂexible indexing and search techniques. Metric access methods (MAMs) provide this flexibility, because they only assume that the dissimilarity between two data objects is modeled by a distance metric. Furthermore, scalable solutions can be built with the help of distributed MAMs.
Both IF4MI and RS4MI, which are presented in this thesis, represent metric access methods. IF4MI belongs to the group of centralized MAMs. It is based on an inverted file and thus offers a hybrid access method providing text retrieval capabilities in addition to content-based search in arbitrary metric spaces. In opposition to IF4MI, RS4MI is a distributed MAM based on resource description and selection techniques. Here, data objects are physically distributed. However, RS4MI is by no means restricted to a certain type of distributed information retrieval system. Various application ﬁelds for the resource description and selection techniques are possible, for example in the context of visual analytics. Due to the metric space assumption, possible application fields go far beyond content-based image retrieval applications which provide the example scenario here.
Bias Volume 18 is a book that is dedicated to critically unpack the meaning of the call to re-write the Bible made by the first President of Zimbabwe, Canaan S. Banana in 1991. In this book, the author engages with Banana’s written works and makes critical observations regarding the call to re-write the Bible. This book argues that re-writing was proposed as a means to an end by Banana. It is demonstrated that what Banana intended was eradicating injustice, violence and inequality in the Middle East which was fuelled by the “ideology of chosenness”, which was sustained by a use of the Bible. Once it became clear the end was not re-writing the Bible, this work moved on to consider alternative means to achieving the same end. The search for alternatives leads the author to consider “the way of Europe”, that is, de-biblification or a watered down de-biblification, which is named partial de-biblification in this work. Finally, the author proposes a “critical biblification” as a viable alternative to re-writing or de-biblification. This book, in honour of Banana, calls for socially and contextually relevant biblical studies.
