Introducing Computation to Neuroscience: Selected Papers of George Gerstein (Springer Series in Computational Neuroscience)
by Ad Aertsen Sonja Grün Pedro E. Maldonado Günther PalmThis book brings together a selection of papers by George Gerstein, representing his long-term endeavor of making neuroscience into a more rigorous science inspired by physics, where he had his roots. Professor Gerstein was many years ahead of the field, consistently striving for quantitative analyses, mechanistic models, and conceptual clarity. In doing so, he pioneered Computational Neuroscience, many years before the term itself was born. The overarching goal of George Gerstein’s research was to understand the functional organization of neuronal networks in the brain. The editors of this book have compiled a selection of George Gerstein’s many seminal contributions to neuroscience--be they experimental, theoretical or computational--into a single, comprehensive volume .The aim is to provide readers with a fresh introduction of these various concepts in the original literature. The volume is organized in a series of chapters by subject, ordered in time, each one containing one or more of George Gerstein’s papers.
Limiting Future Collision Risk to Spacecraft: An Assessment of NASA's Meteoroid and Orbital Debris Programs
by Aeronautics Space Engineering BoardDerelict satellites, equipment and other debris orbiting Earth (aka space junk) have been accumulating for many decades and could damage or even possibly destroy satellites and human spacecraft if they collide. During the past 50 years, various National Aeronautics and Space Administration (NASA) communities have contributed significantly to maturing meteoroid and orbital debris (MMOD) programs to their current state. Satellites have been redesigned to protect critical components from MMOD damage by moving critical components from exterior surfaces to deep inside a satellite's structure. Orbits are monitored and altered to minimize the risk of collision with tracked orbital debris. MMOD shielding added to the International Space Station (ISS) protects critical components and astronauts from potentially catastrophic damage that might result from smaller, untracked debris and meteoroid impacts. Limiting Future Collision Risk to Spacecraft: An Assessment of NASA's Meteoroid and Orbital Debris Program examines NASA's efforts to understand the meteoroid and orbital debris environment, identifies what NASA is and is not doing to mitigate the risks posed by this threat, and makes recommendations as to how they can improve their programs. While the report identified many positive aspects of NASA's MMOD programs and efforts including responsible use of resources, it recommends that the agency develop a formal strategic plan that provides the basis for prioritizing the allocation of funds and effort over various MMOD program needs. Other necessary steps include improvements in long-term modeling, better measurements, more regular updates of the debris environmental models, and other actions to better characterize the long-term evolution of the debris environment.

Stepping-Stones to the Future of Space Exploration: A Workshop Report
by Aeronautics Space Engineering BoardNASA’s Human Exploration and Development of Space (HEDS) program within the Office of Space Flight has proposed a new framework for space technology and systems development—Advanced Systems, Technology, Research, and Analysis (ASTRA) for future space flight capabilities. To assist in the development of this framework, NASA asked the National Research Council to convene a series of workshops on technology policy issues concerning the relationship of the various stakeholders in advancing human and robotic exploration and development of space. The first workshop, which is the topic of this report, focused on policy issues about the development and demonstration of space technologies. Four policy topics—selected by the project steering committee as the foci of this first workshop—are discussed in the report: the rationale for human and robotic space exploration; technology as a driver for capability transformation; risk mitigation and perception; and international cooperation and competition.
Bacilli and Agrobiotechnology (Bacilli in Climate Resilient Agriculture and Bioprospecting)
by Abhinav Aeron M. Tofazzal Islam Mahfuz Rahman Piyush Pandey Chaitanya Kumar JhaThis volume of comprehensive reviews updates our knowledge of research and commercialization of Bacillus-based products in agriculture and the environmental sector. The last couple of decades have witnessed tremendous growth of research on Bacillus species. Many of these species can produce industrial enzymes, and can act simultaneously as biofertilizers and as biopesticides inhibiting important phytopathogens. This "biocontrol" activity is now elucidated by a number of genomic and metabolomic studies. Bacillus formulations are being patented and commercialized on a regular basis. Understanding the biology, ecology and mechanism of action of these bacteria will play a role in the promotion of Bacillus-based products to support green technology in agriculture and agro-based industries.
Ethical Tensions from New Technology: The Case of Agricultural Biotechnology
by Philipp Aerni Rachel A. Ankeny Bartosz Bartkowski Heather J. Bray Bradley Martin Jones Deepthi E. Kolady Jane Kolodinsky Katie M. MacDonald Kelly A. McKinley Desmond Ng Frauke Pirscher Roberto Quiroz Dane Scott Shivendra Kumar Srivastava Debra M. Strauss Insa Theesfeld Johannes Timaeus Corrine Valdivia Duane WindsorThe introduction of new technologies can be controversial, especially when they create ethical tensions as well as winners and losers among stakeholders and interest groups. While ethical tensions resulting from the genetic modification of crops and plants and their supportive gene technologies have been apparent for decades, persistent challenges remain. This book explores the contemporary nature, type, extent and implications of ethical tensions resulting from agricultural biotechnology specifically and technology generally. There are four main arenas of ethical tensions: public opinion, policy and regulation, technology as solutions to problems, and older versus new technologies. Contributions focus on one or more of these arenas by identifying the ethical tensions technology creates and articulating emerging fault lines and, where possible, viable solutions. Key features include: Focusing on contemporary challenges created by new and emerging technologies, especially agricultural biotechnology. Identifying a unique perspective by considering the problem of ethical tensions created or enhanced by new technologies. Providing an interdisciplinary perspective by including perspectives from sociologists, economists, philosophers and other social scientists. This book will be of interest to academics in agricultural economics, sociology and philosophy and policymakers concerned with introducing new technology into agriculture.
Global Business in Local Culture: The Impact Of Embedded Multinational Enterprises (SpringerBriefs in Economics)
by Philipp AerniThis book examines the impact of multinational enterprises (MNEs) on local economies, and presents selected case studies of MNEs operating in low income countries. By balancing external social and environmental costs against its corresponding benefits, the book demonstrates that MNEs can have a positive net-impact on local development if they build up social capital by embedding themselves in local economies and engaging responsibly with local stakeholders. By doing so MNEs contribute to inclusive growth, a cental pillar of the UN Sustainable Development Goals. In this context, the book challenges popular narratives in civil society and academia that frame foreign direct investment (FDI) merely as a threat to human rights and sustainable development. Moreover, it offers practical guidance for globally operating businesses seeking to establish progressive Corporate Social Responsibility (CSR) strategies of their own.
Aerogels Handbook (Advances in Sol-Gel Derived Materials and Technologies)
by Michel Andre Aegerter Matthias M. Koebel Nicholas LeventisAerogels are the lightest solids known. Up to 1000 times lighter than glass and with a density as low as only four times that of air, they show very high thermal, electrical and acoustic insulation values and hold many entries in Guinness World Records. Originally based on silica, R&D efforts have extended this class of materials to non-silicate inorganic oxides, natural and synthetic organic polymers, carbon, metal and ceramic materials, etc. Composite systems involving polymer-crosslinked aerogels and interpenetrating hybrid networks have been developed and exhibit remarkable mechanical strength and flexibility. Even more exotic aerogels based on clays, chalcogenides, phosphides, quantum dots, and biopolymers such as chitosan are opening new applications for the construction, transportation, energy, defense and healthcare industries. Applications in electronics, chemistry, mechanics, engineering, energy production and storage, sensors, medicine, nanotechnology, military and aerospace, oil and gas recovery, thermal insulation and household uses are being developed with an estimated annual market growth rate of around 70% until 2015.

Media and Science-Religion Conflict: Mass Persuasion in the Evolution Wars (Routledge Studies in Religion)
by Thomas AechtnerThis book examines why the religion-science skirmishes known as the Evolution Wars have persisted into the 21st century. It does so by considering the influences of mass media in relation to decision-making research and the Elaboration Likelihood Model, one of the most authoritative persuasion theories. The book’s analysis concentrates on the expression of cues, or cognitive mental shortcuts, in Darwin-sceptic and counter-creationist broadcasts. A multiyear collection of media generated by the most prominent Darwin-sceptic organizations is surveyed, along with rival publications from supporters of evolutionary theory described as the pro-evolutionists. The analysed materials include works produced by Young Earth Creationist and Intelligent Design media makers, New Atheist pacesetters, as well as both agnostic and religious supporters of evolution. These cues are shown to function as subtle but effective means of shaping public opinion, including appeals to expertise, claims that ideas are being censored, and the tactical use of statistics and technical jargon. Contending that persuasive mass media is a decisive component of science-religion controversies, this book will be of keen interest to scholars of Religion, Science and Religion interactions, as well as researchers of Media and Communication Studies more generally.
Platinum Monolayer Electrocatalysts
by Radoslav Adzic Nebojsa MarinkovicThis book describes a science and technology of a new type of electrocatalysts consisting of a single atomic layer of platinum on suitable supports. This development helped overcome three major obstacles—catalysts‘ cost, activity, and stability—for a broad range of fuel cell applications. The volume begins with a short introduction to the science of electrocatalysis, covering four reactions important for energy conversion in fuel cells. A description follows of the properties of metal monolayers on electrode surfaces, and underpotential deposition of metals. The authors then describe the concept of Pt monolayer electrocatalysts and its implications and their synthesis by galvanic displacement of less-noble metal monolayers and other methods. The main part of the book presents a discussion of catalysts’ characterization and catalytic properties of Pt monolayers for the four main reactions of electrochemical energy conversion: oxygen reduction and oxidation of hydrogen, methanol and ethanol. The book concludes with a treatment of scale-up syntheses, fuel cell tests, catalysts’ stability and application prospects.

Virtual Reality Designs
by Adriana Peña Pérez Negrón Graciela Lara López Héctor Rafael Orozco AguirreVirtual Reality is not real life. Instead it is life-like creations using computer-generated scenarios. Human behavior is replicated in virtual scenarios, where every detail is controlled by computers, and in situations that can be repeated under the same conditions. Based on technology and design, the user can experience presence. In the virtual world, users are embodied in avatars that represent them and are the means to interact with the virtual environment. Avatars are graphical models that behave on behalf of the human behind them. The user avatar is a proxy that also backs interaction with others, allowing computer-mediated interactions. Analyses directed to understand people’s perceptions, personal and social behavior in computer mediated interactions, comprise a multidisciplinary area of study that involves, among others, computer science, psychology and sociology. In the last two decades a number of studies supported by Virtual Reality have been conducted to understand human behavior, in some cases the implications of the technology, or to reproduce artificial human behavior. This book presents a collection of studies from recognized researchers in the area.

Of Maybugs and Men: A History and Philosophy of the Sciences of Homosexuality
by Pieter R. Adriaens Andreas De BlockA much-needed exploration of the history and philosophy of scientific research into male homosexuality. Questions about the naturalness or unnaturalness of homosexuality are as old as the hills, and the answers have often been used to condemn homosexuals, their behaviors, and their relationships. In the past two centuries, a number of sciences have involved themselves in this debate, introducing new vocabularies, theories, arguments, and data, many of which have gradually helped tip the balance toward tolerance and even acceptance. In this book, philosophers Pieter R. Adriaens and Andreas De Block explore the history and philosophy of the gay sciences, revealing how individual and societal values have colored how we think about homosexuality. The authors unpack the entanglement of facts and values in studies of male homosexuality across the natural and human sciences and consider the extent to which science has mitigated or reinforced homonegative mores. The focus of the book is on homosexuality’s assumed naturalness. Geneticists rephrased naturalness as innateness, claiming that homosexuality is innate—colloquially, that homosexuals are born gay. Zoologists thought it a natural affair, documenting its existence in myriad animal species, from maybugs to men. Evolutionists presented homosexuality as the product of natural selection and speculated about its adaptive value. Finally, psychiatrists, who initially pathologized homosexuality, eventually appealed to its naturalness or innateness to normalize it. Discussing findings from an array of sciences—comparative zoology, psychiatry, anthropology, evolutionary biology, social psychology, developmental biology, and machine learning—this book is essential reading for anyone interested in what science has to say about homosexuality.
