Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos.

In January 2005, the German government enacted a substantial reform of the welfare system, the so-called "Hartz IV reform." This book evaluates key characteristics of the reform from a microeconometric perspective. It investigates whether a centralized or decentralized organization of welfare administration is more successful to integrate welfare recipients into employment. Moreover, it analyzes the employment effects of an intensified use of benefit sanctions and evaluates the effectiveness and efficiency of the most frequently assigned Active Labor Market Programs. The analyses have a focus on immigrants, who are highly over-represented in the German welfare system. "

Digitalfotografie wird in der aktuellen Literatur stets als DIGITALfotografie verstanden. Dieses Buch versucht bewusst, zu einem besseren Verstandnis der modernen Fotografie zu fuhren, indem das erfolgreiche Zusammenwirken von klassischer mit digitaler Technologie genauso im Fokus steht wie Techniken und Besonderheiten der Digitalfotografie selbst. Die Grundlagen werden dabei theoretisch erlautert und an Bildbeispielen gezeigt. Hinzu kommen besondere Themen der Digitalfotografie wie Farbe und Schwarzweiss, Rausch- und Staubkorrektur, Internetpublikation, Urheberrechtsfragen und die Moglichkeiten des "digitalen Negativs," der raw-Datei. Neben Photoshop wird weitere einschlagige Software wie GIMP und C1 behandelt."
