This book is an essential contribution to the description of fuzziness in information systems. Usually users want to retrieve data or summarized information from a database and are interested in classifying it or building rule-based systems on it. But they are often not aware of the nature of this data and/or are unable to determine clear search criteria. The book examines theoretical and practical approaches to fuzziness in information systems based on statistical data related to territorial units. Chapter 1 discusses the theory of fuzzy sets and fuzzy logic to enable readers to understand the information presented in the book. Chapter 2 is devoted to flexible queries and includes issues like constructing fuzzy sets for query conditions, and aggregation operators for commutative and non-commutative conditions, while Chapter 3 focuses on linguistic summaries. Chapter 4 presents fuzzy logic control architecture adjusted specifically for the aims of business and governmental agencies, and shows fuzzy rules and procedures for solving inference tasks. Chapter 5 covers the fuzzification of classical relational databases with an emphasis on storing fuzzy data in classical relational databases in such a way that existing data and normal forms are not affected. This book also examines practical aspects of user-friendly interfaces for storing, updating, querying and summarizing. Lastly, Chapter 6 briefly discusses possible integration of fuzzy queries, summarization and inference related to crisp and fuzzy databases. The main target audience of the book is researchers and students working in the fields of data analysis, database design and business intelligence. As it does not go too deeply into the foundation and mathematical theory of fuzzy logic and relational algebra, it is also of interest to advanced professionals developing tailored applications based on fuzzy sets.
The Velvet Revolution in November 1989 brought about the collapse of the authoritarian communist regime in what was then Czechoslovakia, marking the beginning of the country's journey towards democracy. Though members of the elite have spoken about the transition to democracy, the experiences of ordinary people have largely gone untold. In Velvet Revolutions, Miroslav Vanek and Pavel Mücke examine the values of everyday citizens who lived under so-called real socialism, as well as how their values changed after the 1989 collapse. Based on 300 interviews, Vanek and Mücke give voice to everyone from farmers to managers, service workers to marketing personnel, manual laborers to members of the armed forces. Compelling and diverse, the oral histories touch upon the experience - and absence - of freedom, the value of family and friends, the experience of free time, and perceptions of foreign nations. Data from opinion polls conducted between 1970 and 2013 factor into the book's analysis, creating a well-rounded view of the ways in which popular thoughts, trends, and attitudes changed as Czech society transitioned from communism to democracy. From this rich foundation, Velvet Revolutions builds a multi-layered view of Czech history before 1989 and during the subsequent period of democratic transformation.

A bold new collection of the writings of Miroslav Krleža, in English for the first time Miroslav Krleža was a giant of Yugoslav literature, yet remarkably little of his writing has appeared in English. In a body of work that spans more than five dozen books, including novels, short stories, plays, poetry, and essays, Krleža steadfastly pursued a radical humanism and artistic integrity. Harbors Rich in Ships gives English-speaking readers an unprecedented opportunity to appreciate the astonishing breadth of Krleža’s literary creations. Beautifully translated by Željko Cipriš, this collection of seven representative early texts introduces a new audience to three stories from Krleža’s renowned antimilitarist book, The Croatian God Mars; an autobiographical sketch; a one-act play; a story from his collection of short stories; One Thousand and One Deaths; and his signature drama, The Glembays, a satirical account of the crime-ridden origins of one of Zageb’s most aristocratic families. Born in 1893 Zagreb, then a city in the Austro-Hungarian Empire, Miroslav Krleža died in 1981 Zagreb, after it had become part of Croatia, a republic in socialist Yugoslavia. He was educated in military academies that served the Hapsburg monarchy, however, after fighting on the Eastern Front during the First World War, he was sickened by the War’s lethal nationalism and became a fervent anti-militarist. Krleža joined the Communist Party of Yugoslavia in 1918, but his opposition to Stalin’s artistic dictum of social realism, as well as his refusal to support Stalin’s purges, led to his expulsion from the Party in 1939. He nevertheless helped found several literary and political journals, and became a driving force in Yugoslavia’s literature. This collection will help readers of all interests and ages see just why Krleža is considered among the best of the literary moderns.
