A Portrait of the Scientist as a Young Woman: A Memoir
by Lindy Elkins-Tanton"Fierce, absorbing, and ultimately inspiring." —ELIZABETH KOLBERT"One of the finest scientific memoirs ever written." —DAVID W. BROWNFrom one of the world’s leading planetary scientists, a luminous memoir of exploration on Earth, in space, and within oneself—equal parts ode to the beauty of science, meditation on loss, and roadmap for personal resilienceDeep in the asteroid belt between Mars and Jupiter, three times farther from the sun than the Earth is, orbits a massive asteroid called (16) Psyche. It is one of the largest objects in the belt, potentially containing the equivalent of the world’s total economy in metals, though they cannot be brought back to Earth. But (16) Psyche has the potential to unlock something even more valuable: the story of how planets form, and how our planet formed. Soon we will find out, thanks to the extraordinary work of Lindy Elkins-Tanton, the Principal Investigator of NASA’s $800 million Psyche mission, and the second woman ever to be awarded a major NASA space exploration contract.The journey that brought her to this place is extraordinary. Amid a childhood of terrible trauma, Elkins-Tanton fell in love with science as a means of healing and consolation. But still she wondered, was forced to wonder: as a woman, was science “for her”? In answering that question, she takes us from the wilds of the Siberian tundra to the furthest reaches of outer space, from the Mayo Clinic, where Elkins-Tanton battled ovarian cancer while writing the Psyche proposal, to NASA’s Jet Propulsion Laboratory, where her team brought that proposal to life.A Portrait of the Scientist as a Young Woman is a beautifully-constructed memoir that explores how a philosophy of life can be built from the tools of scientific inquiry. It teaches us how to approach difficult problems by asking the right questions and truly listening to the answers—and how we may find meaning through exploring the wonders of the universe around us.

Positioning Synthetic Biology to Meet the Challenges of the 21st Century
by Board on Life Sciences Division on Earth and Life Studies National Academy of Engineering Stephanie Joyce Anne-Marie Mazza Committee on Science, Technology, and Law Policy and Global Affairs National Research Council Steven KendallSynthetic biology -- unlike any research discipline that precedes it -- has the potential to bypass the less predictable process of evolution to usher in a new and dynamic way of working with living systems. Ultimately, synthetic biologists hope to design and build engineered biological systems with capabilities that do not exist in natural systems -- capabilities that may ultimately be used for applications in manufacturing, food production, and global health. Importantly, synthetic biology represents an area of science and engineering that raises technical, ethical, regulatory, security, biosafety, intellectual property, and other issues that will be resolved differently in different parts of the world. As a better understanding of the global synthetic biology landscape could lead to tremendous benefits, six academies -- the United Kingdom's Royal Society and Royal Academy of Engineering, the United States' National Academy of Sciences and National Academy of Engineering, and the Chinese Academy of Science and Chinese Academy of Engineering -- organized a series of international symposia on the scientific, technical, and policy issues associated with synthetic biology. Positioning Synthetic Biology to Meet the Challenges of the 21st Century summarizes the symposia proceedings.
Positive Impact Investing: A Sustainable Bridge Between Strategy, Innovation, Change and Learning (Sustainable Finance)
by Karen WendtThis book illustrates the impact that a focus on environmental and social issues has on both de-risking assets and fostering innovation. Including impact as a new cornerstone of the investment triangle requires investors and clients to align interests and values and understand needs. This alignment process functions as a catalyst for transforming organizational culture within an organization and therefore initiates the external impact of the organization, but also its internal transformation, which in turn escalates the creation of impact. Describing how culture is the social glue permeating all disciplines of an organization, the book demonstrates how organizational alignment can be achieved in order to allow strategic speed, innovation and learning, and provides examples of how impact can be achieved and staff mobilized It particularly focuses on impact investing, impact entrepreneurship, innovation, de-risking asset, green investment solutions and investor movements to counteract climate change and implementing the United Nations Sustainable Development Goals, highlighting culture, communication, and strategy.
Positive Neuropsychology: Evidence-Based Perspectives on Promoting Brain and Cognitive Health
by John J. RandolphPositive psychology—the study and promotion of character strengths, positive emotion, optimism, and resilience—has gained considerable momentum and support over the last 20 years. More recently, neuropsychology has begun to embrace related perspectives. In the first edition of Positive Neuropsychology, an extensive collection of perspectives from national leaders in neuropsychology clarified the importance of promoting cognitive health through various means. The present edition expands on the first edition, with four new chapters and updates of all previous chapters. Topics include the importance of physical, social, and intellectual engagement across the lifespan; nutrition and brain health; novel technologies used to maintain brain health and functional independence; compensating for and preventing cognitive limitations; and strategies to promote brain health in clinical and other settings. Chapters reveal not only the benefits of understanding cognitive health and optimal outcomes across the lifespan, but also emerging avenues for practitioners to expand their work into non-traditional settings. Bringing new dimensions to the neuroscience, wellness, and positive psychology literatures, Positive Neuropsychology will interest a wide range of academics and clinicians, including neuropsychologists, clinical and health psychologists, geriatricians, primary care physicians, cognitive neuroscientists, and other healthcare professionals.

Positive Plant Interactions and Community Dynamics
by Francisco I. PugnaireEver since the concept of the "struggle for life" became the heart of Darwin's theory of evolution, biologists have studied the relevance of interactions for the natural history and evolution of organisms. Although positive interactions among plants have traditionally received little attention, there is now a growing body of evidence showing the ef
Positive Psychology and Biodiversity Conservation: Health, Wellbeing, and Pro-Environmental Action (Routledge Studies in Conservation and the Environment)
by Jolanta Burke Darren Clarke Jimmy O'Keeffe Sean CorriganThis book reveals how pro‑environmental actions can boost individuals’ and communities’ psychological, social, and emotional wellbeing, resulting in positive environmental changes.Pro‑environmental actions are often viewed as being motivated by anxiety, shame, or anger. However, emerging research indicates that they can also become a source of positive affect, life meaning, engagement, and other wellbeing outcomes. This book turns the current research and practice of pro‑environmental action on its head. Drawing from the field of positive psychology, a rapidly developing science of wellbeing, the book explores new perspectives on how researchers and practitioners can influence engagement in pro‑environmental initiatives. It provides ways in which individuals passionate about the environment can reframe their feelings and thoughts and allow their newly gained perspective to improve their wellbeing, and outlines approaches to support and encourage those less motivated to engage in pro‑environmental actions. The book draws on research from the biodiversity project called Let It Bee, but also looks at examples of other pro‑environmental research, such as water conservation, recycling, and reducing the consumption of meat. This book can be used as a guide for changing how stakeholders motivate people to engage in pro‑environmental action.This book will be essential reading for students and scholars of biodiversity conservation, environmental sustainability, ecosystem services, and environmental psychology.

Positive Tipping Points Towards Sustainability: Understanding the Conditions and Strategies for Fast Decarbonization in Regions (Springer Climate)
by J. David Tàbara Alexandros Flamos Diana Mangalagiu Serafeim MichasThis open access book provides the first comprehensive review of the state of the art of social tipping points applied to energy systems from a social interdisciplinary perspective. It does so by presenting a novel theory of systemic and transformative change, linking it to empirical cases assisted with relevant assessment methodologies, including modeling. The authors unveil the narratives and visions, the transformative capacities as well as deliberate strategies and collective actions that at one point in time have been able - or were prevented - to tip a given social-ecological system towards low-carbon, sustainable trajectories in diverse high-intensive carbon regions around the world. This volume shows that self-reinforcing learning feedbacks connecting transformative solutions and strategies across scales and domains can be induced by targeted policy interventions both in local and regional contexts. It further indicates how changes in behavioral patterns, supported by good governance of disruptive technologies, carbon (dis)investment and finance processes as well as new forms of civic engagement, can create the necessary transformative enabling conditions for the emergence of positive tipping points towards low-carbon sustainable futures. The book is a must-read for students, researchers, and scholars, as well as policy-makers and practitioners interested in a better understanding of sustainability, climate, and energy issues and in assessing the potential impacts and effectiveness of strategic interventions aimed at accelerating just sustainable decarbonization processes.

Positives Impact Investing: Eine nachhaltige Brücke zwischen Strategie, Innovation, Wandel und Lernen
by Karen WendtDieses Buch veranschaulicht die Auswirkungen, die eine Konzentration auf ökologische und soziale Themen sowohl auf die Risikominderung von Anlagen als auch auf die Förderung von Innovationen hat. Die Einbeziehung der Auswirkungen als neuer Eckpfeiler des Anlagedreiecks erfordert, dass Investoren und Kunden ihre Interessen und Werte aufeinander abstimmen und die Bedürfnisse verstehen. Dieser Abstimmungsprozess fungiert als Katalysator für die Veränderung der Organisationskultur innerhalb einer Organisation und initiiert somit die externe Wirkung der Organisation, aber auch ihre interne Veränderung, die wiederum die Schaffung von Wirkung verstärkt. Das Buch beschreibt, wie Kultur der soziale Klebstoff ist, der alle Disziplinen einer Organisation durchdringt, und zeigt auf, wie eine organisatorische Ausrichtung erreicht werden kann, um strategische Schnelligkeit, Innovation und Lernen zu ermöglichen, und liefert Beispiele dafür, wie Wirkung erzielt und Mitarbeiter mobilisiert werden können. Es konzentriert sich insbesondere auf Impact Investing, Impact Entrepreneurship, Innovation, De-Risking-Asset, grüne Investitionslösungen und Investorenbewegungen, um dem Klimawandel entgegenzuwirken und die Ziele für nachhaltige Entwicklung der Vereinten Nationen umzusetzen, und beleuchtet dabei Kultur, Kommunikation und Strategie.
Positron Emission Tomography
by Birendra Kishore DasThis book provides basic information about the relatively new and evolving technology -positron emission tomography- for its clinical applications and practical guidance for the referring physicians. Chapters cover application of PET in various clinical settings including oncology, cardiology, and neurology with a focus on role in various cancers. Because most of the new PET equipments come as hybrid machines with CT or MRI, two chapters have been included at the end of the book to provide basic and comprehensive information about these two technologies. Molecular imaging is going to revolutionize the way we practice medicine in the future. It will lead to more accurate diagnosis of diseases and its extent which will lead to better management and better outcomes. In the history of medicine no imaging modality has ever become so popular for use in such a short time as has the PET technology. PET imaging is mostly used in oncology, neurology and cardiology but also finds application in other situations such as infection imaging. The main focus, of course, is in management of cancer patients. PET (PET-CT) is not only very sensitive as it can detect changes in abnormal biochemical processes at cellular level but in one go all such areas can be detected in a whole body scan. It can show response to therapy, eradication of the disease or recurrence during the follow-up period. One of the main differences between a PET scan and other imaging tests like CT scan or MRI is that the PET scan reveals the cellular level metabolic changes occurring in an organ or tissue. This is important and unique because disease processes begin with functional changes at the cellular level. A PET scan can detect these very early changes whereas a CT or MRI detect changes much later as the disease begins to cause changes in the structure of organs or tissues. Some cancers, especially lymphoma or cancers of the head and neck, brain, lung, colon, or prostate, in very early stage may show up more clearly on a PET scan than on a CT scan or an MRI. A PET scan can measure such vital functions as blood flow, oxygen use, and glucose metabolism, which can help to evaluate the effectiveness of a patient's treatment plan, allowing the course of care to be adjusted if necessary. Apart from its vital role in oncology it can estimate brain's blood flow and metabolic activity. A PET scan can help finding nervous system problems, such as Alzheimer's disease, Parkinson's disease, multiple sclerosis, transient ischemic attack (TIA), amyotrophic lateral sclerosis (ALS), Huntington's disease, stroke, and schizophrenia. It can find changes in the brain that may cause epilepsy. PET scan is also increasingly being used to find poor blood flow to the heart, which may mean coronary artery disease. It can most accurately estimate the extent of damage to the heart tissue especially after a heart attack and help choose the best treatment, such as coronary artery bypass graft surgery, stenting or medical treatment. It can also contribute significantly in identifying areas exactly where radiotherapy is to be targeted avoiding unnecessary radiation exposure to surrounding tissue.
Positron Emission Tomography
by Malik E. Juweid Otto S. HoekstraOncological imaging has thoroughly changed in the past decade, especially due to the introduction of PET and 18FDG. In Positron Emission Tomography, expert referring specialists and professional imagers seek to help bridge some of the knowledge gaps in several oncological domains. The book's goal is to aid in the improvement of communicative competences: to communicate scan findings so that the referring specialist receives proper advice from the imager, and that, alternatively, the referring one provides the imager with appropriate clinical details to allow for a proper interpretation, and that the referring specialist is aware of the possibilities and limitations of the requested technology. While it focuses on FDG PET, other radiopharmaceuticals are covered as well, where appropriate. Written for the highly respected Methods in Molecular BiologyTM series, this volume provides the kind of detailed description and implementation advice that is crucial for getting optimal results. Authoritative and convenient, Positron Emission Tomography serves as an excellent reference for oncologists, surgeons, radiotherapists, radiologists, nuclear medicine physicians, and pathologists desiring a stronger synergy within their vital efforts.

The first part focuses on recent advances in radiotracer probe development to enable the detection of materials, from large macromolecules to complicated drug-like structures. The next section describes how key physiological and pathophysiological processes can be interrogated and quantifiably measured with this imaging technique. Finally, chapters examine important technological developments in the field that are revolutionizing the way these innovative PET probes are utilized in the clinic. Written for the highly successful Methods in Molecular Biology series, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step and readily reproducible laboratory protocols, as well as tips on troubleshooting and avoiding known pitfalls. Authoritative and practical, Positron Emission Tomography: Methods and Protocols serves as an ideal guide for researchers looking to use imaging to revolutionize the way we diagnose and treat disease.
Positron Profilometry: Probing Material Depths for Enhanced Understanding (SpringerBriefs in Materials)
by Jerzy DryzekThis book provides a comprehensive overview of positron profilometry, specifically focusing on the analysis of defect depth distribution in materials. Positron profilometry plays a crucial role in understanding and characterizing defects in a wide range of materials, including metals, semiconductors, polymers, and ceramics. By analyzing the depth distribution of defects, researchers can gain insights into various material properties, such as crystal structure, defect density, and diffusion behavior. The author's extensive research spanning a period of two decades has primarily centered on subsurface zones. These regions, located beneath the surface and subjected to various surface processes, play a crucial role in generating defect distributions. Three experimental techniques and their data analysis are described in detail: a variable-energy positron beam (VEP) called sometimes a slow positron beam, a technique called implantation profile depth scanning (DSIP), and a sequential etching (SET) technique. The usability of these techniques is illustrated by many examples of measurements by the author and others.

This book provides a detailed discussion of hazard identification, dose-response assessment, exposure assessment, and risk characterization for each.Possible Health Effects of Exposure to Residential Electric and Magnetic Fields also discusses the tools available to measure exposure, common types of exposures, and what is known about the effects of exposure. The committee looks at correlations between EMF exposure and carcinogenesis, mutagenesis, neurobehavioral effects, reproductive and developmental effects, effects on melatonin and other neurochemicals, and effects on bone healing and stimulated cell growth.
Possible Knowledge: The Literary Forms of Early Modern Science
by Debapriya SarkarThe Renaissance, scholars have long argued, was a period beset by the loss of philosophical certainty. In Possible Knowledge, Debapriya Sarkar argues for the pivotal role of literature—what early moderns termed poesie—in the dynamic intellectual culture of this era of profound incertitude. Revealing how problems of epistemology are inextricable from questions of literary form, Sarkar offers a defense of poiesis, or literary making, as a vital philosophical endeavor.Working across a range of genres, Sarkar theorizes “possible knowledge” as an intellectual paradigm crafted in and through literary form. Sixteenth- and seventeenth-century writers such as Spenser, Bacon, Shakespeare, Cavendish, and Milton marshalled the capacious concept of the “possible,” defined by Philip Sidney as what “may be and should be,” to construct new theories of physical and metaphysical reality. These early modern thinkers mobilized the imaginative habits of thought constitutive to major genres of literary writing—including epic, tragedy, romance, lyric, and utopia—in order to produce knowledge divorced from historical truth and empirical fact by envisioning states of being untethered from “nature” or reality.Approaching imaginative modes such as hypothesis, conjecture, prediction, and counterfactuals as instruments of possible knowledge, Sarkar exposes how the speculative allure of the “possible” lurks within scientific experiment, induction, and theories of probability. In showing how early modern literary writing sought to grapple with the challenge of forging knowledge in an uncertain, perhaps even incomprehensible world, Possible Knowledge also highlights its most audacious intellectual ambition: its claim that while natural philosophy, or what we today term science, might explain the physical world, literature could remake reality. Enacting a history of ideas that centers literary studies, Possible Knowledge suggests that what we have termed a history of science might ultimately be a history of the imagination.
