Quality Assurance in the Analytical Chemistry Laboratory - D. Brynn Hibbert - Bog - Oxford University Press Inc - Plusbog.dk

Quality Assurance in the Analytical Chemistry Laboratory - D. Brynn Hibbert - Bog - Oxford University Press Inc - Plusbog.dk

Analytical chemical results touch everyones lives can we eat the food? do I have a disease? did the defendant leave his DNA at the crime scene? should I invest in that gold mine? When a chemist measures something how do we know that the result is appropriate? What is fit for purpose in the context of analytical chemistry? Many manufacturing and service companies have embraced traditional statistical approaches to quality assurance, and these have been adopted by analytical chemistry laboratories. However the right chemical answer is never known, so there is not a direct parallel with the manufacture of ball bearings which can be measured and assessed. The customer of the analytical services relies on the quality assurance and quality control procedures adopted by the laboratory. It is the totality of the QA effort, perhaps first brought together in this text, that gives the customer confidence in the result. QA in the Analytical Chemistry Laboratory takes the reader through all aspects of QA, from the statistical basics and quality control tools to becoming accredited to international standards. The latest understanding of concepts such as measurement uncertainty and metrological traceability are explained for a working chemist or her client. How to design experiments to optimize an analytical process is included, together with the necessary statistics to analyze the results. All numerical manipulation and examples are given as Microsoft Excel spreadsheets that can be implemented on any personal computer. Different kinds of interlaboratory studies are explained, and how a laboratory is judged in proficiency testing schemes is described. Accreditation to ISO 17025 or OECD GLP is nearly obligatory for laboratories of any pretension to quality. Here the reader will find an introduction to the requirements and philosophy of accreditation. Whether completing a degree course in chemistry or working in a busy analytical laboratory, this book is a single source for an introduction into quality assurance.

Republic in Peril - David C. (campbell Professor Of History Hendrickson - Bog - Oxford University Press Inc - Plusbog.dk

It has become a staple among critics of American foreign policy to refer to the United States''s approach as "liberal imperialism." By this they mean that America''s globalist agenda and its willingness to use force in theaters across the globe derives from its desire to evangelize the gospel of liberalism and thereby extend the reach of a US-dominated democratic capitalist order. These critics point to the presidency of Woodrow Wilson and trace how this agenda evolved over the next century. The dominance of liberal ideology, they argue, is so all-encompassing that virtually all of the main variants within the modern US foreign policy tradition, from anti-communism to neoliberalism to neoconservatism, fit under liberalism''s umbrella. In Republic in Peril, the eminent foreign policy scholar David C. Hendrickson turns this thesis on its head. A trenchant critic of America''s quest for global dominance, Hendrickson argues not only that liberalism is not the culprit, but is in fact where we should turn because it offers a powerful critique of both militarized interventionism and the US quest for full-spectrum global dominance. Covering all of the major episodes of the past century, he shows how the US has fully abandoned a tradition of republican liberalism that dates back to the Founders. The republican liberal tradition, which dominated US foreign policy for over a century, mandated non-intervention and the promotion of peace. This "golden rule" policy toward other nations served America well, he contends, and many of the pathologies that plague US foreign policy now--particularly its disastrous approach to the Middle East--can be traced to the desertion of the republican liberal tradition. He therefore advocates returning to the more collegial form of internationalism ("iso-internationalism") that preceded Wilsonianism. Combining both a rich historical overview of modern American foreign policy with a forceful indictment of the illiberal straitjacket in which US has bound itself, Republic in Peril provides a genuinely original defense of liberalism in the service of peaceful non-intervention--a position that contemporary critics of aggressive liberalism are sure to find surprising.
