The thesis explores computable model theory, merging model-theoretic concepts with recursion theory. It begins with a review of key model-theoretic principles, particularly the Baldwin-Lachlan theorem on uncountably categorical theories, before delving into recursion theory and the priority method. The core focus is on the recursive spectrum of uncountably categorical theories, examining which models possess computable presentations. This comprehensive and well-explained work serves as an accessible introduction for logicians interested in this active research area.

Carl Mengers "Grundsatze der Volkswirthschaftslehre" erscheinen 1871 und markieren die Geburtsstunde der Osterreichischen Schule der Nationalokonomie. 150 Jahre spater kennen mehr Menschen in mehr Landern die Osterreichische Schule als je zuvor.Carl Menger, Ludwig Mises und Friedrich Hayek werden verteufelt oder wie Popstars verehrt. Ihre Kopfe zieren Poster und T-Shirts in aller Welt. Die Wurzeln der heutigen Neo-Austrian School liegen aber in Wien, wo zwischen 1871 und 1934 Wissenschaft, Philosophie, Kunst und Kaffeehauskultur einander zu Hochstleistungen inspirieren. Von diesen interdisziplinaren und vielfaltigen Wiener Ursprungen und ihren globalen Folgen handelt dieses Buch. Moge es als Fussnote zur glorreichen Wiener Spataufklarung Wissen vermitteln, Ideen stiften, zum Nachdenken und tolerant-kritischen Diskutieren anregen - und hoffentlich auch ein wenig unterhalten!

This book presents a concise introduction to the epistemology and methodology of the Austrian School of economics as defended by Ludwig von Mises. The author provides an innovative interpretation of Mises’ arguments in favour of the a priori truth of praxeology, the received view of which contributed to the academic marginalisation of the Austrian School. The study puts forward a unique argument that Mises – perhaps unintentionally – defends a form of conventionalism. Chapters in the book include detailed discussions of individualism, historicism, epistemological positions, and essentialism. The author goes on to discuss Mises’ justification of the fundamental axiom and proposes a conventionalist interpretation. By presenting praxeology as a conventionalist research programme, the author aims to reinvigorate the interaction between the Austrian School, mainstream economics, and the philosophy of science. This comprehensive reconstruction is suitable for economists interested in the history and philosophy of their discipline, as well as for philosophers of science.
