Colloidal Dispersions by Earl K. Fischer. Preface: This monograph is planned as a guide to the theory and practice of the dispersion of solids in liquid media. Throughout the writing I have had in mind readers in several pro fessional categories: one is the physical and colloid chemist who is un familiar with the technical aspects of the subject; another is the scientist in industry who is compelled by the exigencies of his work to concentrate on product development but finds that an understanding of theory is the most effective basis on which to design new products; a third is the production supervisor who is interested in the science and engineering underlying the operations in his care but who is too busy to seek their exposition in widely scattered places. There are others, I hope, who will also find the volume interesting and usable. The topics forming the substance of this book are part of the large province of colloid science. An effort has been made to provide a coherent account of the physical properties of colloidal dispersions and the methods for producing them. Innovations and refinements in research techniques have brought a new insight to the structure of these dispersions. In particular, mention should be made of methods for particle-size measurement, experimental means for gauging the interaction of dispersed particles, and new reagents that offer a measure of control for some of the physical properties. There remain, of course, unanswered questions, and the subject abounds with engaging and important research problems. This book is intended to supplement the well-known and easily ac cessible monographs on surface and colloid chemistry. Information has been drawn fromdiverse sources. In an effort to keep the book of moderate size I have been perplexed by the inevitable problem of selec tion, for pertinent material is to be found in the literature of many in dustries and branches of science. I have endeavored to document the work adequately and to bring subjects into their correct historical per spective. Where available information ran low, I have, on occasion, taken the liberty of speculating, and the reader will find hypotheses advanced at various points through the book.

Die Frage nach dem Umfang sozialer Ungleichheit im Deutschen Kaiserreich gilt in der historischen Forschung als zentral fur das Verstandnis des 19. Jahrhunderts und fur die Folgewirkungen im 20. Jahrhundert. Die Studie des Historikers und Volkswirts Hendrik K. Fischer uber das Konsumverhalten privater Haushalte zwischen 1871 und 1914 findet hochst innovative Antworten auf diese Frage und leistet damit einen wertvollen Beitrag zur neueren historischen Sozialstruktur- und Konsumforschung. Die Grundlage der Studie bilden knapp 4.000 Haushaltsrechnungen aus dem Untersuchungszeitraum, die nahezu das gesamte gesellschaftliche Spektrum abdecken: eine in dieser Breite noch nie erschlossene und genutzte Datenquelle. Aus den heterogenen Quellen gewinnt Fischer einen Datensatz, der das Konsumhandeln reprasentativ abzubilden vermag. Dieser "Kolner Datensatz" stellt der empirisch-historischen Konsumforschung eine neuartige und wichtige Basis zur Verfugung, fur die es etwas Vergleichbares zurzeit nicht gibt und deren Analysepotenzial noch lange nicht ausgeschopft sein durfte. Die statistische Auswertung des Datensatzes ist methodisch ebenso innovativ: Mit Hilfe einer Clusteranalyse werden verschiedene reprasentative Konsummuster fur die Zeit des Deutschen Kaiserreichs identifiziert, die wesentlich neue Aussagen uber das Konsumhandeln und damit uber sozial differenzierte Formen der Lebensfuhrung in dieser Periode erlauben. Fischers Untersuchung liefert Ergebnisse, die vermeintlich sichere Kenntnisse uber die sozialen Verhaltnisse im Deutschen Kaiserreich infrage stellen."

Die Medienmarkte konvergieren. Digitalisierung und technische Innovationen fuhren zu wachsenden Verzahnungen und Kompatibilitaten der traditionellen Medien- und Kommunikationsplattformen. Musik-, Film- oder TV-Inhalte konnen uber Internet oder mobile Telekommunikation verbreitet werden und sind als digitale Datensatze schnell verfugbar. Triple Play" und Interaktionsangebote liefern Massen- und Individualkommunikation aus einer Hand.

Mit dem Zusammenwachsen der Markte gewinnt die Gesamtheit der medienrechtlichen Rahmenbedingungen fur die Branchenbeteiligten zunehmend an Bedeutung.

Das Buch vermittelt einen strukturierten Uberblick uber das Medienrecht, die Rechtsbeziehungen der Beteiligten und die Entwicklung der Markte. Neben den rechtsspezifischen Aspekten der Konvergenz werden u.a. Fragen der Vertragsgestaltung und der Abgrenzung von Lizenzrechten thematisiert."

This carefully collected volume of eight essays and 24 supporting documents allows access to the best and latest scholarship about mainland British North America. This book demonstrates how differences in race, ethnicity, gender, and social status were continually negotiated throughout Britain's North American colonies. It includes essays about Native Americans, the transatlantic slave trade, the rise of gentility, regulation of the sexual behavior of both white and black women, and the creation of new religious practices. Overall, "Colonial American History" reveals that this amalgamation of cultures presented the European colonists, Native Americans and Africans alike with the opportunity - and necessity - to establish new identities and create new forms of community and authority.

The book includes a general introduction, chapter introductions, and supporting documents for each essay. The documents - diaries, letters, trial summaries, treaties, slave codes, and travel narratives - are designed to illuminate key issues raised in the essays and facilitate lively, informed classroom discussion.

Poetry. Winner of the Washington Prize for 2013. A pregnancy memoir that unfolds through a series of poems about art, the book engages images of maternity--from the Madonna to the monster--to explore kinship, community, and mortality. The radical changes of a woman's body and role transform not just the individual but art, culture, and language themselves.

Geodesy (the measurement of the size and shape of the earth), fascinating since the time of Erathosenes, became a basic science for the space program. Irene Fischer was a leader in the construction of the World Geodetic System (has an Earth reference ellipsoid named in her honor) when it was still being done by surveyors, piecing together terrestrial, gravitational and astronomical data. By the 1970s, satellite geodesy and marine geodesy were just coming into their own. Using her career, Fischer revels in explaining how the science unfolded, and how misunderstandings occur across scientific fields, eg, why the standard ocean and the geoid do not easily translate across the fields of oceanography and geodesy. Her account should appeal to those writing the history of women in science. Government science, too, is less well studied than academic science even though some fields, such as geodesy, were always government led. Fischer provides food for thought, as well, to those who claim to study the management of science in bureaucratic settings different from those of industry or academia. such as why Columbus' used a figure for the size of the earth's circumference that was so much smaller than Erastothenes' or Posidonius' (with the added benefit of making it easier to persuade his patrons).
