This book is unique in that its stress is not on the mastery of a programming language, but on the importance and value of interactive problem solving. The authors focus on several specific interest worlds: mathematics, computer science, artificial intelligence, linguistics, and games; however, their approach can serve as a model that may be applied easily to other fields as well. Those who are interested in symbolic computing will find that Interactive Problem Solving Using LOGO provides a gentle introduction from which one may move on to other, more advanced computational frameworks or more formal analysis. What is of primary importance, however, is the text's ability -- through its presentation of rich, open-ended problems -- to effectively cultivate crucial cognitive skills.

Walter Benjamin holds a unique fascination for students and scholars interested in the question of modernity. The most original thinker of Weimar Germany, Benjamin has become something of a cultural icon and his works are often regarded with awe rather than critical scrutiny. This book offers surprising new insights from a number of perspectives -- sociology, history, women's studies, literary and cultural studies -- and investigates unexplored areas of Benjamin scholarship to arrive at a critically balanced perception of his work. There are four main sections:* a critical re-evaluation of Benjamin's concepts of history and modernity in light of postmodernist discourses;* a discussion of aspects of Benjamin's literary scholarship; * a re-evaluation of Benjamin's writings on media and performance theories; and * an investigation of Benjamin's peculiar 'utopianism' which includes a critical consideration of sexual/gender politics.

The book is on methods of reconstruction of past climate, climate changes, oceanography of the South Atlantic (including the Southern Ocean) and the cycling of biochemical components in the ocean. Information about past ocean conditions is provided by so-called paleoceanographic proxies (parameters with approximate unobservable environmental variables, e.g. surface water temperature). Use of proxies and their development has been a major theme of the Collaborative Research Project at the University of Bremen for almost 10 years. In this volume we summarize our results in relation to these proxy studies. Each chapter gives an overview of a specific proxy, provides particular findings obtained in the South Atlantic and ends with an outlook on future perspectives with respect to the proxy described. Therefore it is suitable for lecturers, graduate students and scientists working in the field of climate reconstruction from ocean sediments.

This book constitutes the refereed proceedings of the Third International Symposium on End-User Development, IS-EUD 2011, held in Torre Canne, Italy, in June 2011. The 14 long papers and 21 short papers presented were carefully reviewed and selected for inclusion in the book. In addition the volume contains 2 keynote speeches, 14 doctoral consortia, and information on 3 workshops. The contributions are organized in topical sections on mashups, frameworks, users as co-designers, infrastructures, methodologies and guidelines, beyond the desktop, end-user development in the workplace, meta-design, and supporting end-user developers.

Paleoceanographic proxies provide infonnation for reconstructions of the past, including climate changes, global and regional oceanography, and the cycles of biochemical components in the ocean. These prox­ ies are measurable descriptors for desired but unobservable environmental variables such as tempera­ ture, salinity, primary productivity, nutrient content, or surface-water carbon dioxide concentrations. The proxies are employed in a manner analogous to oceanographic methods. The water masses are first characterized according to their specific physical and chemical properties, and then related to particular assemblages of certain organisms or to particular element or isotope distributions. We have a long-standing series of proven proxies available. Marine microfossil assemblages, for instance, are employed to reconstruct surface-water temperatures. The calcareous shells of planktonic and benthic microorgan­ isms contain a wealth of paleoceanographic information in their isotopic and elemental compositions. Stable oxygen isotope measurements are used to detennine ice volume, and MglCa ratios are related to water temperatures, to cite a few examples. Organic material may also provide valuable infonnation, e. g. , about past productivity conditions. Studying the stable carbon isotope composition of bulk organic matter or individual marine organic components may provide a measure of past surface-water CO 2 conditions within the bounds of certain assumptions. Within the scope of paleoceanographic investigations, the existing proxies are continuously evolving and improving, while new proxies are being studied and developed. The methodology is improved by analysis of samples from the water column and surface sediments, and through laboratory experiments.

The thirty chapters of this innovative international study are all devoted to the topic of the play within the play. The authors explore the wide range of aesthetic, literary-theoretical and philosophical issues associated with this rhetorical device, not only in terms of its original meta-theatrical setting – from the baroque idea of a theatrum mundi onward to contemporary examples of postmodern self-referential dramaturgy – but also with regard to a variety of different generic applications, e.g. in narrative fiction, musical theatre and film. The authors, internationally recognized specialists in their respective fields, draw on recent debates in such areas as postcolonial studies, game and systems theories, media and performance studies, to analyze the specific qualities and characteristics of the play within the play: as ultimate affirmation of the ‘self’ (the ‘Hamlet paradigm’), as a self-reflective agency of meta-theatrical discourse, and as a vehicle of intermedial and intercultural transformation. The challenging study, with its underlying premise of play as a key feature of cultural anthropology and human creativity, breaks new ground by placing the play within the play at the centre of a number of intersecting scholarly discourses on areas of topical concern to scholars in the humanities.
