Now in flexi-cover, this visually stunning collection of Klimt's landscape paintings brings to light a lesser-known aspect of the Viennese painter's uvre. While Klimt is largely revered for his opulent, symbol-laden portraits of the Viennese bourgeoisie, these works were just one aspect of his artistic expression. His landscapes represent an important facet of his career and are a valuable contribution to the school of European nature painting. For many years the artist travelled to the Austrian and Italian countryside during the summer, where he took advantage of the extraordinary light and spectacular hues to paint and sketch landscapes. Among the most exquisite of Klimt's landscapes are those in which he experimented with composition and style. Accompanied by scholarly essays, the images reproduced in this book comprise all extant landscapes from this brilliant artist, proving that his mastery extends beyond portraiture and revealing themes that appeared throughout his life's work.

This textbook mainly addresses beginners and readers with a basic knowledge of object-oriented programming languages like Java or C#, but with little or no modeling or software engineering experience – thus reflecting the majority of students in introductory courses at universities. Using UML, it introduces basic modeling concepts in a highly precise manner, while refraining from the interpretation of rare special cases. After a brief explanation of why modeling is an indispensable part of software development, the authors introduce the individual diagram types of UML (the class and object diagram, the sequence diagram, the state machine diagram, the activity diagram, and the use case diagram), as well as their interrelationships, in a step-by-step manner. The topics covered include not only the syntax and the semantics of the individual language elements, but also pragmatic aspects, i.e., how to use them wisely at various stages in the software development process. To this end, the work is complemented with examples that were carefully selected for their educational and illustrative value. Overall, the book provides a solid foundation and deeper understanding of the most important object-oriented modeling concepts and their application in software development. An additional website offers a complete set of slides to aid in teaching the contents of the book, exercises and further e-learning material.

This book constitutes the refereed proceedings of the 12th International Conference on Electronic Commerce and Web Technologies (EC-Web) held in Toulouse, France, in August/September 2011. The 25 papers accepted for EC-Web, selected from 60 submissions, are organized into eight topical sections on semantic services, business processes and services, context-aware recommender systems, intelligent agents and e-negotiation systems, collaborative filtering and preference learning, social recommender systems, agent interaction and trust management, and innovative strategies for preference elicitation and profiling.

Dieses Lehrbuch vermittelt die Grundlagen der objektorientierten Modellierung anhand von UML und bietet eine kompakte Einführung in die fünf Diagramme Klassendiagramm, Anwendungsfalldiagramm, Zustandsdiagramm, Sequenzdiagramm und Aktivitätsdiagramm. Diese decken die wesentlichen Konzepte ab, die für die durchgängige objektorientierte Modellierung in einem kompletten Softwareentwicklungsprozess benötigt werden. Besonderer Wert wird auf die Verdeutlichung des Zusammenspiels unterschiedlicher Diagramme gelegt. Die präsentierten Konzepte werden anhand von illustrativen Beispielen erklärt.

A powerful gallery-system, able to implement and sustain Austrian art on foreign markets, never developed in Vienna where private patronage and artists associations continued to play a much more significant role.

Despite the existence of a large literature dedicated to the art market, the management of art galleries remains a black box as both buyers and sellers put a high value on discretion. This paper overcomes the traditional lack of quantitative data by analysing the complete books of one of the most successful French galleries at the end of the 19th century: Goupil, Boussod & Valadon. This original database covers the sale of more than 40,000 artworks that occurred between 1860 and 1914. Rapidity to sell artworks was a key element in Goupil's strategy. As a whole Goupil sold 71% of artworks bought. Out of the sold artworks, almost 80% were sold within a year (with 22% before the acquisition reflecting orders). Changes in ownership allow us to quantify changes in business strategy. The first owner required a lower mark-up for the artists in residence it was sponsoring and higher ones for nobles and art dealers. The second owner followed a similar strategy but also required a higher mark-up from former branches such as Knoedler.
