The past two decades in the United States have seen an immense liberalization and expansion of women's roles in society Recently, however, some women have turned away from the myriad, complex choices presented by modern life and chosen instead a Jewish orthodox tradition that sets strict and rigid guidelines for women to follow.
Lynn Davidman followed the conversion to Orthodoxy of a group of young, secular Jewish women to gain insight into their motives. Living first with a Hasidic community in St. Paul, Minnesota, and then joining an Orthodox synagogue on the upper west side of Manhattan, Davidman pieced together a picture of disparate lives and personal dilemmas. As a participant observer in their religious resocialization and in interviews and conversations with over one hundred women, Davidman also sought a new perspective on the religious institutions that reach out to these women and usher them into the community of Orthodox Judaism.
Through vivid and detailed personal portraits, Tradition in a Rootless World explores women's place not only in religious institutions but in contemporary society as a whole. It is a perceptive contribution that unites the study of religion, sociology, and women's studies..

By the U.S. Navy (1951). First came the vacuum tube, then the transistor, right? Not really. In between there is another "lost" entity. Electronics engineers of the 1950's believed the rugged little magnetic amplifier was going to replace the less reliable vacuum tube in all its functions up to a megacycle. Originating in the USA but adopted and developed by the Nazis for the V2 missile, the mag amp after WWII found a clique of boosters among U.S. electronics engineers. Still evident in some regulators, the mag amp can also magnify, modulate, switch, invert, convert, phase shift, multiply, and even compute. It requires zero maintenance and can handle thousands of amperes. Modulate your Tesla coil with a mag amp. 43 illustrations. Not a reprint. Completely reset and redesigned.A Magnetic Amplifier Bibliography is published separately by High Voltage Press..

Using quirky and sometimes irreverent examples to provide an overview of social science methodology, this new edition of the popular text has been substantially revised to include an in-depth consideration of current hot topics in the constantly evolving field of scientific research, including the trend away from 'hard' (quantitative) research to 'soft' (qualitative) research, advances in computerized analysis of statistical data, and the increasing focus on the cultural context of research.
Part One explores the strengths and limitations of common sense methods of solving puzzles and demonstrates how the scientific method significantly improves our ability to check the reliability and validity of theories.
Part Two introduces the reader to two pre-scientific methods of problem solving: the after-the fact and the before-and- after methods. After noting the strengths and limitations of these pre-scientific methods, the authors explain how the control-group procedure, the classic example of the scientific method, helps overcome the major limitations of the after-the-fact and before-and-after methods.
Part Three explores how scientists measure the internal and external validity of research results.
Part Four examines the methods scientists use to assess subjective information through qualitative research methods: questionnaires, interviews and attitudes and personality scales. Naturalistic observations and archival research extend the reach of social sciences into areas that more controlled research methods cannot go.
Part Five sets out the basic rules for tying numbers to objects and events, how numbers can be used to summarize and describe large amounts of information, and how mathematics helps us to bridge the gap between the known and the unknown.
Part Six charts an explosion of ethical challenges as science pushes its way into every nook and cranny of our lives. Chapter Fourteen focuses on how scientists may communicate their scientific news clearly and effectively. Part Seven engages in a wide-ranging discussion of the history of science and explore how gender influences scientific research..

Cutting-edge in both perspective and approach, this introduction to the social sciences covers ALL the traditional social science concepts — but views them through a modern prism. Using a lively, clear style, it provides a genuinely interdisciplinary exploration of contributions from all six social science disciplines (sociology, anthropology, psychology, economics, political science, geography). Case studies, feature film analyses, maps, and photos highlight important historical events and concepts throughout. Shows the big picture of both transnational and international changes in communications, transportation, economics, finance, environment, and military matters. Presents the world in a fully modern sense — recognizing that it is vastly different today and that this difference affects the subject of the social sciences (human behavior) greatly. Examines many new ideas that have emerged in the last decade — e.g., the expansion of world and regional trade, debt-for-nature swaps as antidotes to deforestation, etc. .
