This monograph on the description and study of representations of the rotation group of three-dimensional space and of the Lorentz group features advanced topics and techniques crucial to many areas of modern theoretical physics. Prerequisites include a familiarity with the differential and integral calculus of several variables and the fundamentals of linear algebra. Suitable for advanced undergraduate and graduate students in mathematical physics, the book is also designed for mathematicians studying the representations of Lie groups, for whom it can serve as an introduction to the general theory of representation. The treatment encompasses all the basic material of the theory of representations used in quantum mechanics. The two-part approach begins with representations of the group of rotations of three-dimensional space, analyzing the rotation group and its representations. The second part, covering representations of the Lorentz group, includes an exploration of relativistic-invariant equations. The text concludes with three helpful supplements and a bibliography.

This book offers analytical methods for studying human work in ergonomics and psychology that are similar to ones utilized by the engineering sciences. SSAT offers not only new qualitative but also formalized and quantitative methods of analysis. This book will describe quantitative methods of task complexity and reliability assessment, application

Every complex human-machine system includes a computer as a critically important means of work. However, an operator's interaction with a computerized system cannot be reduced to only performing computer-based tasks. Today human-computer interaction (HCI) is not limited to trained software users. People of all ages use all different kinds of gadget

Discusses polymer interactions with biologically active and model media as a spur towards using them for medical and surgical purposes and in agriculture. The topics include the degradation of polymers in aggressive media, polyurethanes in biological media, physico-chemical criteria for estimating the efficiency of burn dressings, a kinetic method for estimating the efficiency of biocides, and diagnosing quality and prognosing the safe storage duration of potatoes. The English of the Russian authors is lively but often awkward. Annotation copyrighted by Book News, Inc., Portland, OR

African American Psychology: From Africa to America, Fourth Edition provides comprehensive coverage of the field of African American psychology. Authors Faye Z. Belgrave and Kevin W. Allison skillfully convey the integration of African and American influences on the psychology of African Americans using a consistent theme throughout the text—the idea that understanding the psychology of African Americans is closely linked to understanding what is happening in the institutional systems in the United States. The Fourth Edition reflects notable advances and important developments in the field over the last several years, and includes evidence-based practices for improving the overall well-being of African American communities. New to the Fourth Edition Coverage of current issues affecting African Americans and causing changes in the social-political environment include the Black Lives Matter movement, racial trauma, and more. Content from blogs has been added to chapter-opening cover stories to reflect the more modern ways news and information are obtained. More coverage of literature and research on Blacks throughout the diaspora, especially in Africa, provide historical context and documents heterogeneity among African Americans in the United States. Expanded coverage of topics as a result of recent research includes LGBTQ individuals, African American fathers, colorism, intersectionality, electronic cigarettes, social media, and more.

The 1935 autobiography of Alexander Ziskind Gurwitz, an Orthodox Jew whose lively recounting of his life in Tsarist Russia and his immigration to San Antonio, Texas, in 1910 captures turbulent changes in early twentieth-century Jewish history In 1910, at the age of fifty-one, Alexander Ziskind Gurwitz made the bold decision to emigrate with his wife and four children from southeastern Ukraine in Tsarist Russia to begin a new life in Texas. In 1935, in his seventies, Gurwitz composed a retrospective autobiography, Memories of Two Generations, that recounts his personal story both of the rich history of the lost Jewish world of Eastern Europe and of the rambunctious development of frontier Jewish communities in the United States. In both Europe and America, Gurwitz inhabited an almost exclusively Jewish world. As a boy, he studied in traditional yeshivas and earned a living as a Hebrew language teacher and kosher butcher. Widely travelled, Gurwitz recalls with wit and insight daily life in European shtetls, providing perceptive and informative comments about Jewish religion, history, politics, and social customs. Among the book’s most notable features is his first-hand, insider’s account of the yearly Jewish holiday cycle as it was observed in the nineteenth century, described as he experienced it as a child. Gurwitz’s account of his arrival in Texas forms a cornerstone record of the Galveston Immigration Movement; this memoir represents the only complete narrative of that migration from an immigrant’s point of view. Gurwitz’s descriptions about the development of a thriving Orthodox community in San Antonio provide an important and unique primary source about a facet of American Jewish life that is not widely known. Gurwitz wrote his memoir in his preferred Yiddish, and this translation into English by Rabbi Amram Prero captures the lyrical style of the original. Scholar and author Bryan Edward Stone’s special introduction and illuminating footnotes round out a superb edition that offers much to experts and general readers alike.
