Purposeful Engineering Economics
by Ronald A. ChaddertonPurposeful Engineering Economics stands as a unique and highly original complement to the traditional engineering economics curriculum. This primarily narrative text conveys the essence of an "Austrian" economic perspective on cash flow analysis and decision making in engineering without extensive tables and graphs and requires very little mathematics. The book's objective is to add a new perspective to the usual study of cash flow analysis and solely econometric engineering decision making. The author draws on the methodology of the Austrian Economists--a school of economic thought that bases its study of economic phenomena on the interpretation and analysis of the purposeful actions of individuals. The book includes an array of illustrative case studies examined in detail by the author and emphasizes the importance of market processes and price signals to coordinate engineering plans.

Pursuing Power and Light: Technology and Physics from James Watt to Albert Einstein (Johns Hopkins Introductory Studies in the History of Science)
by Bruce J. HuntIn the nineteenth century, science and technology developed a close and continuing relationship. The most important advancements in physics—the science of energy and the theory of the electromagnetic field—were deeply rooted in the new technologies of the steam engine, the telegraph, and electric power and light. Bruce J. Hunt here explores how the leading technologies of the industrial age helped reshape modern physics.This period marked a watershed in how human beings exerted power over the world around them. Sweeping changes in manufacturing, transportation, and communications transformed the economy, society, and daily life in ways never before imagined. At the same time, physical scientists made great strides in the study of energy, atoms, and electromagnetism. Hunt shows how technology informed science and vice versa, examining the interaction between steam technology and the formulation of the laws of thermodynamics, for example, and that between telegraphy and the rise of electrical science.Hunt’s groundbreaking introduction to the history of physics points to the shift to atomic and quantum physics. It closes with a brief look at Albert Einstein’s work at the Swiss patent office and the part it played in his formulation of relativity theory. Hunt translates his often-demanding material into engaging and accessible language suitable for undergraduate students of the history of science and technology.

Putting Inequality in Context: Class, Public Opinion, and Representation in the United States
by Christopher EllisRising income inequality is highlighted as one of the largest challenges facing the United States, affecting civic participation and political representation. Although the wealthy often can and do exert more political influence, this is not always the case. To fix political inequality, it is important to understand exactly how class divisions manifest themselves in political outcomes, and what factors serve to enhance, or depress, inequalities in political voice. Christopher Ellis argues citizens’—and legislators’—views of class politics are driven by lived experience in particular communities. While some experience is formally political, on an informal basis citizens learn a great deal about their position in the broader socioeconomic spectrum and the social norms governing how class intersects with day-to-day life. These factors are important for policymakers, since most legislators do not represent “the public” at large, but specific constituencies. Focusing on U.S. congressional districts as the contextual unit of interest, Ellis argues individuals’ political behavior cannot be separated from their environment, and shows how income’s role in political processes is affected by the contexts in which citizens and legislators interact. Political inequality exists in the aggregate, but it does not exist everywhere. It is, rather, a function of specific arrangements that depress the political influence of the poor. Identifying and understanding these factors is a crucial step in thinking about what reforms might be especially helpful in enhancing equality of political voice.
Putting Social Movements in Their Place
by Doug Mcadam Hilary Schaffer BoudetThe field of social movement studies has expanded dramatically over the past three decades. But as it has done so, its focus has become increasingly narrow and 'movement-centric'. When combined with the tendency to select successful struggles for study, the conceptual and methodological conventions of the field conduce to a decidedly Ptolemaic view of social movements: one that exaggerates the frequency and causal significance of movements as a form of politics. This book reports the results of a comparative study, not of movements, but of communities earmarked for environmentally risky energy projects. In stark contrast to the central thrust of the social movement literature, the authors find that the overall level of emergent opposition to the projects has been very low, and they seek to explain that variation and the impact, if any, it had on the ultimate fate of the proposed projects.
Putting the Barn Before the House: Women and Family Farming in Early Twentieth-Century New York
by Grey OsterudPutting the Barn Before the House features the voices and viewpoints of women born before World War I who lived on family farms in south-central New York. As she did in her previous book, Bonds of Community, for an earlier period in history, Grey Osterud explores the flexible and varied ways that families shared labor and highlights the strategies of mutuality that women adopted to ensure they had a say in family decision making. Sharing and exchanging work also linked neighboring households and knit the community together. Indeed, the culture of cooperation that women espoused laid the basis for the formation of cooperatives that enabled these dairy farmers to contest the power of agribusiness and obtain better returns for their labor. Osterud recounts this story through the words of the women and men who lived it and carefully explores their views about gender, labor, and power, which offered an alternative to the ideas that prevailed in American society. Most women saw "putting the barn before the house"-investing capital and labor in productive operations rather than spending money on consumer goods or devoting time to mere housework-as a necessary and rational course for families who were determined to make a living on the land and, if possible, to pass on viable farms to the next generation. Some women preferred working outdoors to what seemed to them the thankless tasks of urban housewives, while others worked off the farm to support the family. Husbands and wives, as well as parents and children, debated what was best and negotiated over how to allocate their limited labor and capital and plan for an uncertain future. Osterud tells the story of an agricultural community in transition amid an industrializing age with care and skill.

Pyrethroid Insecticides (The Handbook of Environmental Chemistry #92)
by Ethel EljarratThis book reviews the latest developments concerning the analysis, fate, behaviour and toxicity of pyrethroid insecticides. Over the last few decades, pyrethroid insecticides have increasingly replaced organochlorine pesticides due to their relatively lower mammalian toxicity, selective insecticide activity and lower environmental persistence. They represent 25% of global sales of insecticides, and are considered to be “safe” since they are converted to non-toxic metabolites by oxidative metabolism in fish and by hydrolysis in mammals. However, recent studies have demonstrated their environmental ubiquity, their bioaccumulation and their toxicity in various aquatic and terrestrial organisms, and even in humans. Featuring contributions by leading experts, the book discusses the physico-chemical properties and uses of pyrethroid insecticides; the latest chemical analytical methods; their occurrence in the environment, biota and food; and their isomeric and enantiomeric behaviour. It particularly highlights the toxicological effects and human exposure to pyrethroid insecticides, and also offers insights into the effects of the salmon industry on the marine environment with a case study of sea lice treatment using pyrethroids. This comprehensive book is a valuable source of information for environmental scientists, policymakers and producers interested in issues related to pyrethroid insecticides.

Pyrrhic Progress: The History of Antibiotics in Anglo-American Food Production (Critical Issues in Health and Medicine)
by Claas KirchhellePyrrhic Progress analyses over half a century of antibiotic use, regulation, and resistance in US and British food production. Mass-introduced after 1945, antibiotics helped revolutionize post-war agriculture. Food producers used antibiotics to prevent and treat disease, protect plants, preserve food, and promote animals’ growth. Many soon became dependent on routine antibiotic use to sustain and increase production. The resulting growth of antibiotic infrastructures came at a price. Critics blamed antibiotics for leaving dangerous residues in food, enabling bad animal welfare, and selecting for antimicrobial resistance (AMR) in bacteria, which could no longer be treated with antibiotics. Pyrrhic Progress reconstructs the complicated negotiations that accompanied this process of risk prioritization between consumers, farmers, and regulators on both sides of the Atlantic. Unsurprisingly, solutions differed: while Europeans implemented precautionary antibiotic restrictions to curb AMR, consumer concerns and cost-benefit assessments made US regulators focus on curbing drug residues in food. The result was a growing divergence of antibiotic stewardship and a rise of AMR. Kirchhelle’s comprehensive analysis of evolving non-human antibiotic use and the historical complexities of antibiotic stewardship provides important insights for current debates on the global burden of AMR.
