The paper introduces the problem of unawareness into multi-dimensional Principal–Agent theory. We introduce two key parameters to describe the problem, the extent and the effect of unawareness, show under what conditions it is optimal for the Principal to propose an incomplete or a complete contract, and characterize the incentive power of optimal linear contracts. If Agents differ in their unawareness, optimal incentive schemes can be distorted for both aware and unaware Agents, because, different from standard contract theory, the single-crossing property (...) fails to hold. In this case, even aware Agents can be subject to inefficiently high or low incentives. (shrink)

This paper has the aim of making Johannes von Kries’s masterpiece, Die Principien der Wahrscheinlichkeitsrechnung of 1886, a little more accessible to the modern reader in three modest ways: first, it discusses the historical background to the book ; next, it summarizes the basic elements of von Kries’s approach ; and finally, it examines the so-called “principle of cogent reason” with which von Kries’s name is often identified in the English literature.

Johann Wolfgang von Goethe is most famous for his work on color theory, but he was also an accomplished all-round scientist, studying and writing on anatomy, geology, botany, zoology and meteorology. This book draws together, in Goethe's own words, his key ideas on nature, science and scientific method. Goethe believed that we should study our world and nature as people at home in it, rather than removedly, as if we were aliens from another planet. He adopted a qualitative approach to (...) science at odds with Newton's quantitative methods that were so popular in his day. His is a sensitive science which does not ignore our relationship to nature. The extracts in this book are fascinating and essential reading for anyone who feels that we've lost our spiritual connection to nature. (shrink)

The term of responsibility is ambiguous. In a general sense it means nothing more than answering questions about human behaviour (in Greek: logon didonai; in Latin: rationem reddere). In order to get a more precise sense of responsibility this article discusses concepts of responsibility, worked out by Albert Schweitzer, Hans Jonas, Richard Niebuhr and Dietrich Bonhoeffer. The discussion is concentrated on two problems: (1) extensification of responsibility in accordance with the expansion of technological power; (2) limitation and intensification of responsibility (...) in accordance with human capability and readiness. The central question is that of the subject of responsibility: How becomes man, who abdicates responsibility, ‘the responsible self’ (Niebuhr)? Referring to this question the biblical language is of great importance as the word, which re-establishes communication between God and man. Responsibility in the biblical sense means the response to this word of God. Therein lies not only a radicalising and intensifying of responsibility, but also its enabling and limiting. (shrink)

During the Weimar Republic, Siegfried Kracauer established himself as a trenchant theorist of film, culture, and modernity, and he is now considered one of the key thinkers of the twentieth century. When he arrived in Manhattan aboard a crowded refugee ship in 1941, however, he was virtually unknown in the United States and had yet to write his best-known books, _From Caligari to Hitler_ and _Theory of Film_. Johannes von Moltke details the intricate ways in which the American intellectual (...) and political context shaped Kracauer’s seminal contributions to film studies and shows how, in turn, Kracauer’s American writings helped shape the emergent discipline. Using archival sources and detailed readings, von Moltke asks what it means to consider Kracauer as the New York Intellectual he became in the last quarter century of his life. Adopting a transatlantic perspective on Kracauer’s work, von Moltke demonstrates how he pursued questions in conversation with contemporary critics from Theodor Adorno to Hannah Arendt, from Clement Greenberg to Robert Warshow: questions about the origins of totalitarianism and the authoritarian personality; about high and low culture; about liberalism, democracy, and what it means to be human. From these wide-flung debates, Kracauer’s own voice emerges as that of an incisive cultural critic invested in a humanist understanding of the cinema. (shrink)

Johann Gottfried von Herder is one of the most important German philosophers of the eighteenth century, who had enormous influence on later thinkers such as Hegel, Schleiermacher and Nietzsche. His wide-ranging ideas were formative in the development of linguistics, hermeneutics, anthropology and bible scholarship, and even today they retain their vitality and relevance to an extraordinary degree. This volume presents a translation of Herder's most important and characteristic philosophical writings in his areas of central interest, including philosophy of language, philosophy (...) of mind, philosophy of history and political philosophy, as well as his general philosophical program. An introduction sets the writings in their historical context and examines their philosophical achievement. (shrink)

Using a Web search engine is one of today’s most frequent activities. Exploratory search activities which are carried out in order to gain knowledge are conceptualized and denoted as Search as Learning. In this paper, we introduce a novel framework model which incorporates the perspective of both psychology and computer science to describe the search as learning process by reviewing recent literature. The main entities of the model are the learner who is surrounded by a specific learning context, the interface (...) that mediates between the learner and the information environment, the information retrieval backend which manages the processes between the interface and the set of Web resources, that is, the collective Web knowledge represented in resources of different modalities. At first, we provide an overview of the current state of the art with regard to the five main entities of our model, before we outline areas of future research to improve our understanding of search as learning processes.
