Vision is our primary sensory modality, and we are naturally curious as to how the visual system assembles. The visual system is in many ways remarkably simple, a repeating assemblage of neurons and support cells that parse the visual field through precision and redundancy. Through this simplicity the eye has often led the way in our exploration of how an organ is assembled. Eye development has therefore long been a favorite for exploring mechanisms of cell fate choice, patterning and cell signaling.

This volume, which is part of the Current Topics in Developmental Biology series, highlights the exceptional advances over the past 20 years. Chapters emphasize our knowledge of transcription factors and how these generate networks to direct the eye field and associated structures. Topics such as cell fate specification are also explored, along with the potential of Drosophila as a model for lens formation and the progress made in using the Drosophila eye to examine planar cell polarity.
Contributions from researchers who are active in identifying new paradigms to explore

Review of our current state of knowledge

Chapters written by authors with a new generation approach that takes a more systems approach to identifying factors and better defines cell subtypes

The book presents a systematic and compact treatment of the qualitative theory of half-linear
differential equations. It contains the most updated and comprehensive material and represents the first attempt to present the results of the rapidly developing theory of half-linear differential equations in a unified form. The main topics covered by the book are oscillation and asymptotic theory and the theory of boundary value problems associated with half-linear equations, but the book also contains a treatment of related topics like PDE s with p-Laplacian, half-linear difference equations and various more general nonlinear differential equations.
- The first complete treatment of the qualitative theory of half-linear differential equations.
- Comparison of linear and half-linear theory.
- Systematic approach to half-linear oscillation and asymptotic theory.
- Comprehensive bibliography and index.
- Useful as a reference book in the topic.

Enlargement and treaty reform have moved Europe's constitutional debate into the political spotlight. This important new text outlines the main themes of constitutional debate in the EU, analyzes formal and informal constitution-building since the early days of European integration, and introduces the actors and structures behind treaty change.

How have EU-level actors responded to the increase in salience and contestation across the member states? This volume explores and explains the actors’ strategic responses and emphasises that domestic pressure has triggered both depoliticisation and politicisation. Long gone are the times when EU decisions left citizens indifferent, and when the supranational was largely irrelevant for public opinion and electoral politics across the member states. Instead, a string of existential crises has struck and unsettled the Union over more than a decade. These crises have politicised Europe, tested the endurance of the supranational system to its core, and put EU-level actors under unprecedented pressure. This volume explores how and why EU-level actors respond to the various, sometimes competing, ‘bottom-up’ demands, and challenges the view that domestic contestation necessarily limits EU-level room for manoeuvre. Instead, contributions show that domestic pressure can be perceived as either constraining or enabling, with responses, therefore, ranging from the restrained to the assertive. Driven by the survival of the Union, by the preservation of their own powers, and by different perceptions of domestic demands, actors will choose to politicise or depoliticise decision-making, behaviour, and policy outcomes at the supranational level. The volume concludes that whilst domestic pressure triggers supranational responses, such responses should not be assumed to be restraining; they may equally be empowering including for European integration itself. The chapters in this book were originally published as a special issue of the Journal of European Public Policy.

Originally published in 1964, and extensively illustrated with figures and charts, this volume gives an overview of both physical and human geography of the former USSR. The role that the geography of the country has played in shaping historical events and political forces is discussed, as is its role in the economy of the Soviet Union. The geography is examined by topics and regional differences explained within this framework. The book looks at some of the major problems posed by geographical conditions and how they have been tackled and as far as data allows, the success or failure of measures has been assessed.

Die Überlegung, dass Menschen als Subjekte nicht einfach gegeben sind, sondern sich selbst von Anderen her erlernen, kann mit Norbert Ricken als Kerngedanke einer sozialtheoretischen Erziehungswissenschaft verstanden werden. Diesen Gedanken zur Beobachtung eines sozialen Geschehens als eines pädagogischen zugrunde zu legen und im Rückgriff auf philosophische, sozial- und kulturwissenschaftliche Perspektiven zu schärfen, stellt das Hauptanliegen des Buches dar. Die Sozialität von Mensch und Erziehung bildet damit den Ausgangspunkt des hier konturierten Theorie- und Forschungsprogramms.

Die Autorin wirft die Frage auf, welchen Stellenwert insbesondere die Schadenswiedergutmachung und der Tater-Opfer-Ausgleich im Bereich des Wirtschaftsstrafrechts einnehmen. Dabei umfasst das Werk die theoretischen Auseinandersetzungen uber die Anwendbarkeit der Instrumente im wirtschaftsstrafrechtlichen Bereich und grenzt sie zu anderen straf-, zivil- und oeffentlich-rechtlichen Instrumenten ab. Andererseits wird die praktische Relevanz im Rahmen einer qualitativ-empirischen Untersuchung erforscht und die Frage nach opferfreundlicheren Alternativinstrumenten aufgeworfen. Dabei kommt die Autorin dazu, dass die Wiedergutmachung im Wirtschaftsstrafverfahren durchaus Potential hat, sofern die notwendigen Rahmenbedingungen stimmen.

Die Autoren und Autorinnen der Beitrage stellen Forschungsprojekte zu Selbstandigkeit fordernden und kooperativen Arbeitsformen in unterschiedlichen Fachern und Klassenstufen vor. Im Mittelpunkt stehen sechs Beitrage qualitativ-rekonstruktiver Forschung zur Interaktion zwischen Schulern bzw. Schulern und Lehrern im Klassenraum."
