Labor and the Locavore
by Margaret GrayIn the blizzard of attention around the virtues of local food production, food writers and activists place environmental protection, animal welfare, and saving small farms at the forefront of their attention. Yet amid this turn to wholesome and responsible food choices, the lives and working conditions of farmworkers are often an afterthought.Labor and the Locavore focuses on one of the most vibrant local food economies in the country, the Hudson Valley that supplies New York restaurants and farmers markets. Based on more than a decade's in-depth interviews with workers, farmers, and others, Gray's examination clearly shows how the currency of agrarian values serves to mask the labor concerns of an already hidden workforce. She also explores the historical roots of farmworkers' predicaments and examines the ethnic shift from Black to Latino workers. With an analysis that can be applied to local food concerns around the country, this book challenges the reader to consider how the mentality of the alternative food movements implies a comprehensive food ethic that addresses workers' concerns.
Labor in the Era of Globalization
by Clair Brown Barry Eichengreen Michael ReichThe third quarter of the twentieth century was a golden age for labor in the advanced industrial countries, characterized by rising incomes, relatively egalitarian wage structures, and reasonable levels of job security. The subsequent quarter-century has seen less positive performance along a number of these dimensions. This period has instead been marked by rapid globalization of economic activity that has brought increased insecurity to workers. The contributors to this volume, prominent scholars from the United States, Europe, and Japan, distinguish four explanations for this historic shift. These include 1) rapid development of new technologies; 2) global competition for both business and labor; 3) deregulation of industry with more reliance on markets; and 4) increased immigration of workers, especially unskilled workers, from developing countries. In addition to analyzing the causes of these trends, the contributors also investigate important consequences, ranging from changes in collective bargaining and employment relations to family formation decisions and incarceration policy.
Laboratory Accreditation and Data Certification: A System for Success
by Carla H. Dempsey Jimmie D. PettyThis book provides descriptions of current laboratory accreditation schemes and explains why these schemes fall short of assuring data purchasers that the data produced from accredited laboratories are always quality products. The book then presents a system for laboratory accreditation in conjunction with data certification that assures data purchasers their data are useful for the purposes for which they are intended. Simple quality assurance and quality control techniques, in addition to concepts of total quality management, are described and then applied to the environmental laboratory industry. This "System For Success" was developed from real problems and real solutions within the industry and represents an integration of proven techniques that offer a better way to ensure quality laboratory data is obtained. Laboratory Accreditation: A Workable Solution is a must for government officials, environmental professionals, independent environmental laboratories, hazardous waste disposal industries, chemical manufacturers, QA professionals, and testing laboratories.
Laboratory Design, Construction, and Renovation: Participants, Process, and Product
by Committee on Design Construction Renovation of Laboratory FacilitiesLaboratory facilities are complex, technically sophisticated, and mechanically intensive structures that are expensive to build and to maintain. Hundreds of decisions must be made before and during new construction or renovation that will determine how successfully the facility will function when completed and how successfully it can be maintained once put into service. This book provides guidance on effective approaches for building laboratory facilities in the chemical and biochemical sciences. It contains both basic and laboratory-specific information addressed to the user community-the scientists and administrators who contract with design and construction experts. The book will also be important to the design and construction communities-the architects, laboratory designers, and engineers who will design the facility and the construction personnel who will build it-to help them communicate with the scientific community for whom they build laboratory facilities.
Laboratory Exercises for Sensory Evaluation
by Harry T. LawlessLaboratory exercises are a necessary part of science education. They enable students to better understand the principles discussed in lectures, and provide them with hands-on experience of the practical aspects of scientific research. The purpose of this book is to provide students and instructors with a time-tested set of lab exercises that illustrate the common sensory tests and/or sensory principles used in evaluation of foods, beverages and consumer products. The appendices will also include a set of simple problem sets that can be used to teach and reinforce basic statistical tests. Approximately twenty years ago the Sensory Evaluation Division of the Institute of Food Technologists sponsored the preparation of a set of exercises titled "Guidelines for Laboratory Exercises for a Course in Sensory Evaluation of Foods," edited by one of the co-authors (Heymann). This book will provide additional materials from the second author (Lawless), as well as other instructors, in a uniform format that can be easily adopted for course use. Most importantly, the lab exercises will complement the flagship textbook in the field, Sensory Evaluation of Foods: Principles and Practices, 2E, also by Lawless and Heymann and published by Springer. Possible course adoption of the main text along with the lab manual should enhance the sales of these materials.

Laboratory Models for Foodborne Infections (Food Microbiology)
by Dongyou Liu Laszlo EndrenyiResulting from ingestion of inappropriately prepared or stored foods containing pathogenic viruses, bacteria, fungi and parasites, foodborne infections have become a significant source of human morbidity and mortality worldwide in recent decades. This may be largely attributable to the remarkable popularity of convenient, ready-to-eat food products, the dramatic expansion of international food trades, and the continuing growth of immuno-suppressed population groups. Although anti-microbial treatments have played a crucial part in the control of foodborne infections in the past, the emergence and spread of anti-microbial resistance render the existing treatments ineffective. Additionally, our limited understanding of the molecular mechanisms of foodborne infections has thwarted our efforts in the development of efficacious vaccines for foodborne pathogens. Given the obvious benefits of laboratory models in foodborne disease research, a great number of experiments have been conducted toward the elucidation of host-pathogen interactions in and pathogenic mechanisms of foodborne infections. Forming part of the Food Microbiology series, Laboratory Models for Foodborne Infections presents a state-of-the-art review of laboratory models that have proven valuable in deciphering the life cycle, epidemiology, immunobiology, and other key aspects of foodborne pathogens. Written by scientists with respective expertise in foodborne pathogen research, each chapter includes a contemporary summary of a particular foodborne viral, bacterial, fungal, or parasitic infection in relation to its life cycle, epidemiology, clinical features, pathogenesis, host-pathogen interactions, and other related aspects. Besides providing a trustworthy source of information for undergraduates and postgraduates in food microbiology, Laboratory Models for Foodborne Infections offers an invaluable guide for scientists and food microbiologists with interest in exploiting laboratory models for detailed study of foodborne infections.

Laboratory Tests for Unsaturated Soils
by Eng-Choon Leong Martin WijayaThe testing of unsaturated soils requires greater care and effort than that of saturated soils. Although unsaturated soil mechanics has been embraced by geotechnical engineering, engineering practice has not yet caught up as the characterization of unsaturated soils is difficult and time-consuming, and made harder still by a lack of standards. Laboratory Tests for Unsaturated Soils collates test procedures to cover all laboratory tests for characterising unsaturated soils. It covers the background, theory, test procedures, and interpretation of test results. Each test procedure is broken down into simple stages and described in detail. The pitfalls of each test and the interpretation of the test results are explained. Test data and calculation methods are given, along with many numerical examples to illustrate the methods of interpretation and to offer the presentation of typical results. The book is especially useful for students and researchers who are new to the field and provides a practical handbook for engineering applications.
Laboratory Tests for the Assessment of Nutritional Status (Modern Nutrition Ser. #21)
by Howerde E. SauberlichProper nutrition is the single most important component of preventative health care. Heart disease, diabetes, and other ailments are all linked to dietary habits. Accurate nutritional assessment can be a matter of life or death. Laboratory Tests for the Assessment of Nutritional Status explores the expanded number of nutrients that can now be evaluated. The author makes a compelling case for the practice and advancement of this critical health care tool. Nutritional assessment identifies undernutrition, overnutrition, specific nutrition deficiencies, and imbalances. Diligent assessment determines the appropriate nutrition intervention and monitors its effects. This book is a total revision of the 1974 version of the same title co -authored by Sauberlich. Since then, remarkable progress has been made on the methodologies applicable to nutrition status assessment and to the expanded number of nutrients that can be evaluated, especially trace elements. The introduction of high-performance liquid chromatography, amperometric detectors, and other technologies has advanced nutritional assessment by leaps and bounds. Today, nutritionists can gauge the value of microminerals, trace elements, and ultratrace elements. Sauberlich's revision updates the reader to the latest and most important trends in nutrition. These laboratory methods for the assessment of nutritional status are vital for identifying individuals as well as populations with nutritional risks.
Labour Power: Virtual and Actual in Digital Production (Lecture Notes in Morphogenesis)
by Roberto CiccarelliThis book offers a critical account of Karl Marx’s dazzling theory of labour power which is also one of the most influential concepts in the history of contemporary philosophy. Labour power is the dark side of the digital revolution. Working men and women are invisible and treated like human service, flesh and blood automatons or organic extensions of a machine that produces data on its own. Automation is viewed as something magic made possible by algorithms whose life is independent of human beings.Labour power, however, has not disappeared. Without drivers, Uber cannot connect customers on its platform; without searches on its browser, Google grinds to a halt; without us, Facebook or Instagram is desert. Labour power is the dwarf hidden inside the puppet of technology that allows algorithms to be intelligent and make the biggest profits in the history of capitalism.The invisible centrality of labour power is the political enigma of our times. Today a new account of the theory of labour power is needed more than ever in order to understand the political economy of digital capitalism on new grounds. Unlike a long tradition in the history of work, labour power is not only the work or the data it produces, but a potency that does not coincide with its current commodification. The actuality of labour power does not exhaust the virtuality that can be actualised by its faculty. Even when reduced to a commodity, labour power does not exhaust the potency of its being otherwise.Immersed in the constant propaganda that boosts the latest technological inventions, we neglect the fact that this wealth is produced by us and that it could be ours precisely because it is a part of our potential to be other than what we are at present. This book is a vibrant invitation to consider the fact that we are always connected with the potency that is constantly at work in our life. If this were not the case, we would not be alive. If we do not strive to become consciously and collectively active, we will never know.
Labour Problems of Technological Change (Routledge Library Editions: Labour Economics #8)
by L. C. Hunter G. L. Reid D. BoddyFirst published in 1970. This book is concerned with the examination and assessment of the impact of changes in technology on companies in three selected industries: printing, steel and chemicals. Its main focus is on the employment and associated labour market effects of technological change; but part of the rationale for the study as a whole has been to relate these effects to the technological environment of each industry. Accordingly, a good deal of attention has been paid to the character of the innovations themselves and to their implications for the industries in general terms. This title will be of interest to students of Business Studies and Economics.
Labs of Our Own: Feminist Tinkerings with Science
by Sig / GiordanoFrom climate change to COVID-19 to reproductive justice, there has been deep political polarization around science. Labs of Our Own provides a unique entry point into these twenty-first-century science wars by focusing on our affective relationships to science. The book delves into various sites where scientists, teachers, artists, and activists claim to create more democratic access to science—from DIY biology community labs to feminist classrooms to activist science practitioners. The reader will find that these claims for and attempts at democratic sciences not only impact what counts as science and who counts as a scientist but reconfigure who is included in the proper public. Instead of arguing for a knee-jerk defense of science against right-wing attacks, Labs of Our Own builds the case for a feminist, antiracist, decolonial, queer science tinkering practice that intentionally, politically, and ethically acts to produce new challenges to the definition and boundaries of the human.

Labyrinth and Piano Key Weirs
by Sébastien Erpicum Michel Pirotton Frédéric Laugier Jean-Louis Boillat Bernard Reverchon Anton SchleissLabyrinth spillways are almost as old as dam engineering. In spite of the fact that they appear as a very good technical-economical compromise, only 0.1% of large dams are equipped with such weirs. The main reason for this is that traditional labyrinth weirs usually cannot be installed on top of concrete gravity dams as they require a large foundat
Labyrinth and Piano Key Weirs II
by Sébastien Erpicum Michel Pirotton Michael Pfister Frédéric Laugier Guy-Michel Cicero Anton J. SchleissDam engineering is currently experiencing a strong revival of labyrinth oriented weirs. Labyrinth weirs, with a repetitive constructional character and an increased specific discharge capacity, are a very good technical-economical compromise. The concept of Piano Key Weir (PKW), with alveoli developed in overhangs from a reduced support area, enabl
Labyrinth and Piano Key Weirs III: Proceedings of the 3rd International Workshop on Labyrinth and Piano Key Weirs (PKW 2017), February 22-24, 2017, Qui Nhon, Vietnam
by Sébastien Erpicum Michael Pfister Frédéric Laugier Michel Ho Ta KhanhSince the first implementation by Electricité de France on the Goulours dam (France) in 2006, the Piano Key Weir has become a more and more applied solution to increase the discharge capacity of existing spillways. In parallel, several new large dam projects have been built with such a flood control structure, usually in combination with gates. Today, more than 25 Piano Key Weirs are in operation or under construction all over the world. More than 15 years of research and development have enabled detailed investigations of the hydraulic and structural behaviour of the Piano Key Weir complex structure and have provided more and more accurate design equations. Following the proceedings of the first two workshops held in Liege (Belgium – 2011) and Paris (France – 2013), Labyrinth and Piano Key Weirs III collects the contributions presented by people with varied background, from researchers to practitioners, at the 3rd International Workshop on Labyrinth and Piano Key Weirs - PKW 2017 (22-24 February 2017, Qui Nhon, Vietnam). The papers, reviewed and accepted by an International Scientific Committee, summarize the current state-of-the-art on Piano Key Weirs from a theoretical to a practical point of view, and present most of the main projects in operation or under construction. Labyrinth and Piano Key Weirs III is thus a reference for students, practitioners and researchers interested in Dams Engineering.
