Book Description
Typically, laboratory experiments suffer from homogeneous subject pools and self-selectionbiases. The usefulness of survey data is limited by measurement error and by thequestionability of their behavioral relevance. Here we present a method integrating interactiveexperiments and representative surveys thereby overcoming crucial weaknesses of bothapproaches. One of the major advantages of our approach is that it allows for the integrationof experiments, which require interaction among the participants, with a survey of noninteractingrespondents in a smooth and inexpensive way. We illustrate the power of ourapproach with the analysis of trust and trustworthiness in Germany by combiningrepresentative survey data with representative behavioral data from a social dilemmaexperiment. We identify which survey questions intended to elicit people's trust correlate wellwith behaviorally exhibited trust in the experiment. People above the age of 65, highly skilledworkers and people living in bigger households exhibit less trusting behavior. Foreigncitizens, Catholics and people favoring the Social Democratic Party or the ChristianDemocratic Party exhibit more trust. People above the age of 65 and those in good healthbehave more trustworthy or more altruistically, respectively. People below the age of 35, theunemployed and people who say they are in favor of none of the political parties behave lesstrustworthy or less altruistically, respectively.

Book Description
Laboratory experiences as a part of most U.S. high school science curricula have been taken for granted for decades, but they have rarely been carefully examined. What do they contribute to science learning? What can they contribute to science learning? What is the current status of labs in our nation�s high schools as a context for learning science? This book looks at a range of questions about how laboratory experiences fit into U.S. high schools: What is effective laboratory teaching? What does research tell us about learning in high school science labs? How should student learning in laboratory experiences be assessed? Do all student have access to laboratory experiences? What changes need to be made to improve laboratory experiences for high school students? How can school organization contribute to effective laboratory teaching? With increased attention to the U.S. education system and student outcomes, no part of the high school curriculum should escape scrutiny. This timely book investigates factors that influence a high school laboratory experience, looking closely at what currently takes place and what the goals of those experiences are and should be. Science educators, school administrators, policy makers, and parents will all benefit from a better understanding of the need for laboratory experiences to be an integral part of the science curriculum-and how that can be accomplished.

Book Description
Scientific experiments using animals have contributed significantly to the improvement of human health. Animal experiments were crucial to the conquest of polio, for example, and they will undoubtedly be one of the keystones in AIDS research. However, some persons believe that the cost to the animals is often high. Authored by a committee of experts from various fields, this book discusses the benefits that have resulted from animal research, the scope of animal research today, the concerns of advocates of animal welfare, and the prospects for finding alternatives to animal use. The authors conclude with specific recommendations for more consistent government action.

Book Description
Prudent Practices in the Laboratory-the book that has served for decades as the standard for chemical laboratory safety practice-now features updates and new topics. This revised edition has an expanded chapter on chemical management and delves into new areas, such as nanotechnology, laboratory security, and emergency planning. Developed by experts from academia and industry, with specialties in such areas as chemical sciences, pollution prevention, and laboratory safety, Prudent Practices in the Laboratory provides guidance on planning procedures for the handling, storage, and disposal of chemicals. The book offers prudent practices designed to promote safety and includes practical information on assessing hazards, managing chemicals, disposing of wastes, and more. Prudent Practices in the Laboratory will continue to serve as the leading source of chemical safety guidelines for people working with laboratory chemicals: research chemists, technicians, safety officers, educators, and students.

Book Description
As national political fights are waged at the state level, democracy itself pays the price Over the past generation, the Democratic and Republican parties have each become nationally coordinated political teams. American political institutions, on the other hand, remain highly decentralized. Laboratories against Democracy shows how national political conflicts are increasingly flowing through the subnational institutions of state politics—with profound consequences for public policy and American democracy. Jacob Grumbach argues that as Congress has become more gridlocked, national partisan and activist groups have shifted their sights to the state level, nationalizing state politics in the process and transforming state governments into the engines of American policymaking. He shows how this has had the ironic consequence of making policy more varied across the states as red and blue party coalitions implement increasingly distinct agendas in areas like health care, reproductive rights, and climate change. The consequences don’t stop there, however. Drawing on a wealth of new data on state policy, public opinion, money in politics, and democratic performance, Grumbach traces how national groups are using state governmental authority to suppress the vote, gerrymander districts, and erode the very foundations of democracy itself. Required reading for this precarious moment in our politics, Laboratories against Democracy reveals how the pursuit of national partisan agendas at the state level has intensified the challenges facing American democracy, and asks whether today’s state governments are mitigating the political crises of our time—or accelerating them.
