Value-Free Science? Purity and Power in Modern Knowledge
by Robert N. ProctorWhy have scientists shied away from politics, or defended their work as value free? How has the ideal of neutrality come to dominate the world of science? These are some of the central questions that Robert Proctor addresses in his study of the politics of modern science.<P><P> Value-Free Science? emphasizes the importance of understanding the political origins and impact of scientific ideas. Proctor lucidly demonstrates how value-neutrality is a reaction to larger political developments, including the use of science by government and industry, the specialization of professional disciplines, and the efforts to stifle intellectual freedoms or to politicize the world of the academy.<P> The first part of the book traces the origins of value-neutrality prior to the eighteenth century. Plato and Aristotle saw contemplative thought as superior to practical action, and this separation of theory and practice is still invoked today in defense of "neutral science." In the seventeenth century the Baconian search for useful knowledge allowed a new and closer tie between theory and practice, but it also isolated moral knowledge from natural philosophy. Another version of neutrality was introduced by the mechanical conception of the universe, in which the idea of a benevolent, human-centered cosmos was replaced with a "devalorized" view of nature.<P> The central part of the book explores the exclusion of politics and morals with the emergence of the social sciences. Proctor highlights the case of Germany, where the ideal of value-neutrality was first articulated in modern form by social scientists seeking to attack or defend Marxism, feminism, and other social movements. He traces the rise and fall of positivist ethical and economic theory, showing that arguments for value-free science often mask concrete political maneuvers. Finally, he reviews critiques of science that have been voiced in recent debates over critical issues in agricultural science, military research, health and medicine, and biological determinism.<P> This provocative book will interest anyone seeking ways to reconcile the ideals of scientific freedom and social responsibility.

Valued Environments (Routledge Library Editions: Environmental Policy #7)
by John R. Gold Jacquelin BurgessFirst published in 1982. People care about places. Inhabitants demand more participation in the changes proposed for their local environments, activists urge greater protection of countryside and natural environments, decision-makers feel threatened by the antagonism aroused by their powers and plans. The essays in this book have been drawn together to discover what lies behind these expressions of concern and discontent. Valued environments are places for which people feel commitment and affection, places which support a sense of personal identity and well-being. The authors explore the character and constituents of valued environments asking how our experiences of environments may be enhanced. What is the impact of environmental change? How can the future be accommodated in both rural and urban environments without destroying their essential qualities? The reader will find substantive evidence from case studies of environments valued by inhabitants and outsiders which answer these questions. Examples are taken from wilderness areas, fenland, market towns and large cities, commercial streets and residential neighbourhoods, environments of the past and those imagined in science fiction. The essays are united in their focus on the meaning of places and landscapes. The subtle but highly significant role of valued environments is examined thoroughly in the book. It will be of interest to all who care deeply about their surroundings, reflecting perhaps some of their own experiences as well as conveying information about the environmental experiences of others. Students of geography, environmental planning and conservation should also find the book directly relevant to their interests in man-environment relationships.

Values and Technology: Religion and Public Life (Religion And Public Life Ser.)
by James BurkIn 1749 Jean-Jacques Rousseau's Discourse on the Arts and Sciences, surprised leading Enlightenment thinkers who had enthusiastically upheld the positive benefits of humanity's technological advance. Voltaire, who celebrated the ends of civilization, mocked Rousseau's praise for an original creative state of nature in which man enjoyed an optimum level of freedom.Given the unprecedented intrusion of technology into our lives, the question raised by Rousseau's critique may be even more pertinent. In this volume of Religion and Public Life contributors address some of the challenges to conventional morality brought on by the technological augmentation of the social structure. John Barker's essay explores how Luciano Floridi's philosophy of technology has complicated the conventional way of determining what ought to receive moral consideration. Fani Zlatarova provides a practical guide for incorporating ethical components into teaching computer technology.Grant Havers explores the controversies surrounding the biogenetic explosion through an examination of the competing philosophical perspectives and Christopher Vassilopolos examines the science-based justification for taking life. Gabriel R. Ricci looks at recent political history in the United States in order to highlight the sometimes uneasy relationship between science and social policy. Volume 37 is a welcome addition to the acclaimed Religion and Public Life series.
Values at Work: Sustainable Investing and ESG Reporting
by Daniel C. Esty Todd CortSustainable investing is a rapidly growing and evolving field. With investors expressing ever greater interest in environmental, social, and governance (ESG) metrics and reporting, companies face a sustainability imperative and the need to remake their business models to respond to an array of pressing issues including climate change, air and water pollution, racial justice, workplace diversity, economic inequality, privacy, corporate integrity, and good governance. From equities to fixed income and from private equity to impact-investing, investors of all kinds now want to understand which companies will be marketplace leaders in a business future redefined by sustainability.

Readers of the book will be better able to identify and address the hurdles to moving mainstream capital toward more sustainable companies, investments, and projects.
Values in Science Education: The Shifting Sands
by Angela Fitzgerald Alister Jones Cathy Buntting Deborah CorriganIn 2007, the Monash-Kings College London International Centre for the Study of Science and Mathematics Curriculum edited a book called The Re-emergence of Values in Science Education. This book reflects on how values have been considered since this original publication, particularly in terms of socio-cultural, economic and political factors that have impacted broadly on science, technology and society, and more specifically on informal and formal science curricula. Hence, the title of this book has been framed as Values in Science Education: The shifting sands. As in the first book, this collection focuses on values that are centrally associated with science and its teaching, and not the more general notion of values such as cooperation or teamwork that are also important values in current curricula. Such values have indeed become more of a focus in science education. This may be a response to the changing global context, where technological changes have been rapid and accelerating. In such complex and risky environments, it is our guiding principles that become the important mainstays of our decisions and practices. In terms of science education, what is becoming clearer is that traditional content and traditional science and scientific methods are not enough for science and hence science education to meet such challenges. While shifts in values in science education continue, tensions remain in curriculum development and implementation, as evidenced by the continued diversity of views about what and whose values matter most.
Values of Love and Ethical Reflection (Husserlian Legacies: Themes for the 21st Century)
by Edmund HusserlThis first volume of Husserlian Legacies: Themes for the 21st Century focuses on hitherto underexamined dimensions of Husserl’s philosophical thinking and in particular, values and love. Texts in this series draw from the variety of Husserl’s rich original works; they are selected and arranged with the support of the Husserl Archives, Leuven. The texts are made available in English and are primarily targeted to advanced undergraduates, graduate students, and scholars. This volume helps the reader both to investigate the themes of value and love and to gauge their role in Husserl’s reflections on related topics: his analysis of philosophy, the sciences as vocational tasks, the emotions and the community of love, as well as his personalistic reformulation of the categorical imperative. The texts gathered, edited, and translated in this volume have far-reaching implications, ranging from axiology and individual and social ethics to the philosophy of emotions, action theory, and the philosophy of science.
Values, Identity, and Sustainable Development in Africa (Sustainable Development Goals Series)
by Ezra Chitando Eunice KamaaraThis book contends that Africa’s sustainable development must be built on African identity and values. Contributors reflect of the role of values in Africa’s effort to overcome poverty, the focus of SDG 1. The volume reflects on how indigenous values such as Ubuntu constitute a critical resource in addressing poverty. It reiterates the importance of positioning the response to poverty in Africa on the continent’s own, home grown values. Contributors also interrogate how values such as integrity, hard work, tolerance, solidarity, respect and others serve to position Africa strategically to overcome poverty. The volume focuses on how values can help Africa to overcome challenges such as corruption, violence, intolerance, competitive ethnicity, xenophobia, misplaced priorities and others. It provides fresh and critical reflections on the role of values and identity in anchoring Africa’s development in the light of SDG 1.
Valuing Animals: Veterinarians and Their Patients in Modern America (Animals, History, Culture)
by Susan D. JonesOver the course of the twentieth century, the relationship between Americans and their domestic animals has changed dramatically. In the 1890s, pets were a luxury, horses were the primary mode of transport, and nearly half of all Americans lived or worked on farms. Today, the pet industry is a multibillion-dollar-a-year business, keeping horses has become an expensive hobby, and consumers buy milk and meat in pristine supermarkets. Veterinarians have been very much a part of these changes in human-animal relationships. Indeed, the development of their profession—from horse doctor to medical scientist—provides an important perspective on these significant transformations in America's social, cultural, and economic history.In Valuing Animals, Susan D. Jones, trained as both veterinarian and historian, traces the rise of veterinary medicine and its impact on the often conflicting ways in which Americans have assessed the utility and worth of domesticated creatures. She first looks at how the eclipse of the horse by motorized vehicles in the early years of the century created a crisis for veterinary education, practice, and research. In response, veterinarians intensified their activities in making the livestock industry more sanitary and profitable. Beginning in the 1930s, veterinarians turned to the burgeoning number of house pets whose sentimental value to their owners translated into new market opportunities. Jones describes how vets overcame their initial doubts about the significance of this market and began devising new treatments and establishing appropriate standards of care, helping to create modern pet culture.Americans today value domestic animals for reasons that typically combine exploitation and companionship. Both controversial and compelling, Valuing Animals uncovers the extent to which veterinary medicine has shaped—and been shaped by—this contradictory attitude.
Valuing Assessment in Science Education: Pedagogy, Curriculum, Policy
by Alister Jones Deborah Corrigan Richard GunstoneAssessment is a fundamental issue in research in science education, in curriculum development and implementation in science education as well as in science teaching and learning. This book takes a broad and deep view of research involving assessment in science education, across contexts and cultures (from whole countries to individual classrooms) and across forms and purposes (from assessment in the service of student learning to policy implications of system wide assessment). It examines the relationships between assessment, measurement and evaluation; explores assessment philosophies and practices in relation to curriculum and scientific literacy/learning; and details the relationships between assessment and science education policy. The third in a series, Valuing Assessment in Science Education has chapters from a range of international scholars from across the globe and staff from Monash University, King's College London and University of Waikato. The two previous books in the series examined research relevant to the re-emergence of values in science education and teaching across the spectrum of science education as well as across cultural contexts through the professional knowledge of science teaching. This third book now moves to examine different aspects of generating understanding about what science is learnt, how it is learnt, and how it is valued. Valuing Assessment in Science Education will appeal to all those with some engagement with and/or use of research in science education, including research students, academics, curriculum development agencies, assessment authorities, and policy makers. It will also be of interest to all classroom science teachers who seek to keep abreast of the latest research and development and thinking in their area of professional concern.
Valuing Ecosystem Services: Toward Better Environmental Decision-making
by National Research Council of the National AcademiesNutrient recycling, habitat for plants and animals, flood control, and water supply are among the many beneficial services provided by aquatic ecosystems. In making decisions about human activities, such as draining a wetland for a housing development, it is essential to consider both the value of the development and the value of the ecosystem services that could be lost. Despite a growing recognition of the importance of ecosystem services, their value is often overlooked in environmental decision-making. This report identifies methods for assigning economic value to ecosystem services—even intangible ones—and calls for greater collaboration between ecologists and economists in such efforts.
Valuing the Built Environment: GIS and House Price Analysis
by Scott OrfordThis book critically assesses the hedonic pricing technique as a method of imputing monetary values for the implicit attributes of housing. The hedonic technique is widely used, particularly in the US, but increasingly in Europe and Asia and has proved to yield important results and influence cost-benefit analysis. Scott Orford breaks new ground in this volume by exploring hedonic house price models within a geographical rather than purely economic context. He reevaluates the microeconomic theory of housing markets and concludes that only by treating housing market dynamics as inherently spatial can empirical results conform to the theory that underpins them. He also makes conclusions with respect to locational externalities, which have important implications as to how the built environment is valued.
Valuing the Past, Sustaining the Future?: Exploring Coastal Societies, Childhood(s) and Local Knowledge in Times of Global Transition (MARE Publication Series #27)
by Dympna Devine Spyros Spyrou Anne Trine Kjørholt Firouz Gaini Sharon BessellThis book explores questions related to social and cultural sustainability of coastal communities in transition through the lens of childhood. Contributors explore diverse local and national contexts spanning several countries aiming to shed light on the shifting and dynamic interplay between education, knowledge production, society and working life in coastal environments from an intergenerational perspective. Key points that are disclosed are:the current threat to the social and cultural sustainability of coastal communities in different local and national contexts, and the reason they must be preserved the centrality of processes of inter generational transmission of local knowledge to the preservation and development of sustainable coastal communitiesthe central role of children and young people as actors in creating sustainable livelihoods, economies and knowledge in coastal communities for the future?the practices across different country contexts The book will address the challenges to sustainability experienced by local communities in light of local, national and global social and economic changes. Looking at these challenges cross-nationally and through the lens of childhood, and knowledge production across generations, will provide for a much-needed perspective in ongoing discussion on sustainability in coastal communities.
Valvular Heart Disease: A Guide for Cardiovascular Nurses and Allied Health Professionals
by Marian C. Hawkey Sandra B. LauckThis book serves as the “go-to” resource for cardiovascular nurses and other health care practitioners involved in the care of patients with acquired valvular heart disease. It includes unique information about heart valve anatomy and pathophysiology, the complexity of clinical presentations and diagnostic evaluation, patient education and shared decision-making, surgical and transcatheter treatment options, and transition to palliative care. The content focuses primarily on the specialized care of patients with aortic stenosis and regurgitation, and mitral and tricuspid regurgitation. In addition, this unique resource provides timely information to guide a patient-centred and team-driven approach that reflects contemporary and innovative practice in the management of valvular heart disease. The essential topics of strengthening the multidisciplinary Heart Team and programmatic processes of care, the priorities for nursing care, and the multifactorial challenges of managing this complex patient population are explored in detail. Importantly, this resource aims to support all clinicians who are involved in the various timepoints of patients’ full trajectory of care, from their evaluation pathway, admissions for treatment, and long term follow-up. Clinicians require contemporary knowledge and evidence to guide their practice, provide appropriate care for this complex patient population, and contribute to the advancement of practice. To date, there has been little emphasis placed on the management of valvular heart disease in cardiovascular nursing and allied health curriculum. This book fills this gap and addresses the pressing need for a user-friendly resource to guide the care for this growing population in a rapidly changing clinical environment. The editors are international leaders in the care and management of patients with acquired valvular heart disease and program development. They are widely recognized for their pioneering role in shaping the way we care for these patients.
Vampire Forensics: Uncovering the Origins of an Enduring Legend
by Mark Collins JenkinsStories of immortal, night-crawling creatures who feed on victims' blood have frightened and entertained people worldwide since ancient times. In this book, historian Jenkins examines millennia of vampire legends to see what elements of truth (if any) lay behind them. While the author's recounting of folklore and history outweigh the scientific and forensic explanations that he provides for the persistence of vampire legends, this is nonetheless a very entertaining account of vampirism from ancient Persia through to the present day. The discussion of how the Black Plague and other diseases might be at the root of vampirism is alone worth the price of the book, and the excellent bibliography is especially welcome. Given the increased fascination with vampires since the 1990s, this book should have wide appeal. Annotation ©2010 Book News, Inc., Portland, OR (booknews.com)

Vanadium
by Hitoshi MichibataThe publication of Vanadium: Biochemical and Molecular Biological Approaches is particularly timely as it exactly coincides with the centennial anniversary of the discovery of vanadium by Professor Henze, in the blood cells of an ascidian (tunicate) collected in Gulf of Naples in 1911. Vanadium, atomic number 23, covers a wide range of oxidation states (from -2 to +5) and has unpaired electrons. Depending on these properties, a wide variety of enzymes and compounds containing vanadium have been found and the biochemical behaviour of vanadium has been investigated extensively. This monograph provides not only the basic properties and recent advances of vanadium chemistry but also presents recent topics on hyper-accumulators of vanadium, enzymatic roles of vanadium, biochemical functions of vanadium and medicinal functions of vanadium, which have been discovered by Biochemical and Molecular Biological Approaches. Vanadium: Biochemical and Molecular Biological Approaches is aimed at pure and applied chemists, biochemists, pharmaceutical and medical scientists.
Vanadium Oxide-Based Cathode for Supercapacitor Applications: Using Electrodeposition Method (SpringerBriefs in Applied Sciences and Technology)
by Hairus AbdullahThis book highlights the use/application of Vanadium Oxide as a Supercapacitor (SC) material using the electrodeposition method. The preparation methods, material characterization, and performance testing of VOx-based SC are thoroughly discussed. Electrolyte solutions from VCl3 and other metal precursors are used to form V3O5 electrodes on nickel foam (NF). The cathode can deliver a specific capacitance value of 5689 F/g. The work is improved by depositing V3O5 film on Ni(OH)2 to form a bilayer coating on NF substrate. Ni(OH)2 with a nano-sheet structure is used for the purpose of increasing the specific surface area of V3O5 layer which can achieve specific capacitance of 7500 F/g, the energy density of 167 Wh/kg, and the power density of 199 W/kg. After 10,000 charge-discharge cycles, the capacitance retention rate is 93%. Finally, a full cell SC is assembled using the bilayer electrode and active carbon. The asymmetric and symmetric full cells performed the specific capacitances of 390 F/g and 846 F/g, the energy densities of 286 Wh/kg and 170 Wh/kg, and the power densities of 1149 W/kg and 602 W/g, respectively. After 10,000 charge-discharge cycles, the capacitance retention rates of asymmetric and symmetric full cells are 97% and 95%, respectively.

Vanadiumgruppe: Eine Reise durch das Periodensystem (essentials)
by Hermann SiciusHermann Sicius stellt in diesem essential die Elemente der fünften Nebengruppe (Vanadiumgruppe) ausführlich vor. Er zeigt, dass diese Elemente teilweise reaktiv, aber gelegentlich auch sehr reaktionsträge sind, dass sie an der Luft lagernd von einer dünnen, passivierenden Oxidschicht vor weiterer Korrosion geschützt und auch in Säuren nur selten und dann nur unter Anwendung drastischer Methoden löslich sind. Die technische Anwendung zeigt der Autor für diese Elemente auf, die alle sehr harte, hochschmelzende Metalle sind und deren Verbindungen mit Kohlen- und Stickstoff teils extrem hochschmelzende, harte Schleifmaterialien darstellen, die man auch industriell einsetzt. Vanadium findet sich in Stahllegierungen, Tantal in medizinischen Implantaten, Ferroniob als Bestandteil von Gasturbinen oder Vanadium-V-oxid als Katalysator bei der Herstellung von Schwefelsäure.
