The blockchain is the world’s first truly global mechanism for the transfer and storage of value. The distribution of its nodes all around the world and the resulting ‘omniterritorial’ nature of the blockchain create enormous challenges for the law. This book discusses the technological and philosophical underpinnings of the new crypto phenomena. It describes the varying approaches of regulators of different states to capture these phenomena with traditional or new rules. It also addresses the difficulties in determining the applicable private law, in particular the property rules governing virtual assets. The book showcases the conflicts, issues and problems that result from overlapping national rules and suggests avenues for their solution.

In Parallel, creator Matthias Lehmann deftly explores the complexities of being gay at a time when queer relationships were forbidden. Torn between his longing for a family and his simultaneous desire for gay love, Karl Kling hides his homosexuality from his wife and child while pursuing male romances in 1950s Germany. Karl Kling's story is one of revelations, and these he has addressed in a letter to his daughter, Hella, who had disowned Karl many years ago. Karl's letter is a cri de coeur from a father to a daughter he never really got to know, and he comes clean to her about his failed marriages, his fractured family relations--and his love for men. Taking place between the end of World War II and the 1980s, Parallel chronicles Karl's efforts to comply with social norms in order to keep his sexuality a secret. It also paints a picture of a life torn between conformity and rebellion, and the cruel realities of twentieth-century German society, where homosexuality was proscribed and punishable until 1994. Matthias Lehmann poignantly depicts the story of a decades-long yearning to live an open and free life, and the price Karl and those he loves must pay for it. It is also a story of finding the courage to finally tell the truth no matter the obstacles...or the cost.

The third edition is fully updated to include more case studies and to encompass recent events in Jewish history, as well as religion, social life, economics, culture, and gender.Supported by case studies, online references, further reading, maps, and illustrations, The Jews: A History provides students with a comprehensive and wide-ranging grounding in Jewish history.

The internet is one of the newest communication technologies and has run through fundamental technological progress during the last years. During the end of the 1990's many internet firmswere established whose investors expected high revenues. However many of these platforms could not meet the expectations, the stock prices of many firms declined rapidly and many firms filed for bankruptcy. Since 2004 the internet developed to the Web 2.0 which suggests that a better version of the web exists today.Spendings in online advertisements were interestingly not effected by the crash of the internet market at the beginning of the 21st century. Since 1998 the net advertising revenues have increased constantly. In 2008 US-American companies will spend more for internet advertisements than forTV commercials. In the past, famous Web 2.0 websites were sold for high prices: the Holtzbrinck publishing group bought StudiVZ for around 85 million euros, the video website Youtube was soldto Google for 1.65 billion dollars and News Corporation paid 580 million dollars for Myspace.However all of these social networks still have to supply evidence that their company value is not overestimated. As far as the advertisement revenues are concerned none of them generate significant profits yet.In this paper I will analyze the performance of advertisements on Web 2.0 websites as exemplified by social networks. First I will trace the developments that led to the so-called Web 2.0 and define their characteristics. Then I will focus on social networks, analyze their features and the possibilitiesto use them for advertisement purposes. Finally I will analyze several possibilities to advertise on Web 2.0 websites.

Das Lehrbuch führt Studierende der Wirtschaftswissenschaften und der Rechtswissenschaften in die Grundlagen der Finanzwirtschaft ein. Das besondere Anliegen des Buches besteht darin, dem Leser Grundlinien und Zusammenhänge des auf den Kapitalmarkt bezogenen finanzwirtschaftenden Handelns aufzuzeigen, das zu den ökonomischen Funktionen des Finanzierens und des Handelns mit Wertpapieren gehört.

Im Zentrum des Buches steht das Prinzip "Leistung gegen Entgelt": Betriebswirtschaftliches Planen, Entscheiden und Handeln wird beschrieben als das Erstellen von Leistungen und ihre Verwendung gegen Entgelt mit dem Zweck der Gewinnerzielung. Schwerpunkt ist damit zum einen die betriebswirtschaftliche Leistungslehre für Sach- und Dienstleistungen. Zum anderen kann die Teilnahme am Markt nur unter Berücksichtigung der gegenseitigen Verträge geklärt werden. Im Mittelpunkt des Anbietermarketings steht daher die Vertragsangebotspolitik; die absatzpolitischen Instrumente werden darauf bezogen geordnet. Das besondere Konzept des Buches besteht darin, dem Leser Grundlinien und Zusammenhänge des wirtschaftenden Handelns aufzuzeigen. Dazu gehört selbstverständlich, daß die Verbindungen zum Rechnungswesen und zum Recht mit in das Ordnungsgefüge einbezogen werden.

Der Zweck erwerbswirtschaftlicher Betatigungen ist das Erzielen von Entgelteinnahmen mittels der Vermarktung von Leistungen. Auf der Grundlage der Vorgange "Leistung gegen Entgelt" erarbeitet dieses Buch ein zwischen Real-, Wert- und Rechenoekonomie abgestimmtes Konzept. Statt der ublichen Aufteilung in Investitions-, Kosten- und Jahresabschlussrechnung wird eine Gesamtschau des betriebswirtschaftlichen Rechnungswesens entlang den Phasen Rechnen, Planen, Planentscheidung, Vollzugsuberwachung und Abrechnung in seiner sachlich-zeitlichen Struktur vorgestellt.
