Plastic Ocean
by Capt. Charles MooreA prominent seafaring environmentalist and researcher shares his shocking discovery of the Great Pacific Garbage Patch, and inspires a fundamental rethinking of the Plastic Age. In the summer of 1997, Charles Moore set sail from Honolulu returning home after competing in a trans-Pacific race. To get to California, he and his crew took a shortcut through the seldom-traversed North Pacific Subtropical Gyre, a vast "oceanic desert" where winds are slack and sailing ships languish. There, Moore realized his catamaran was surrounded by a "plastic soup." He had stumbled upon the largest garbage dump on the planet--a spiral nebula where plastic outweighed zooplankton, the ocean's food base, by a factor of six to one. In Plastic Ocean, Moore recounts his ominous findings and unveils the secret life and hidden proper ties of plastics. From milk jugs to polymer molecules small enough to penetrate human skin or be unknowingly inhaled, plastic is now suspected of contributing to a host of ailments, including infertility, autism, thyroid dysfunction, and some cancers. An urgent call to action, Moore's sobering revelations will be embraced by activists, concerned parents, and anyone concerned about the deadly impact and implications of this man-made blight.

Plastic Waste Trade: A New Colonialist Means of Pollution Transfer
by Sedat GündoğduThis contributed volume takes a holistic view of the international waste trade and in doing so argues that the transfer of plastic waste from mainly Global North to primarily Global South countries constitutes a form of 21st Century colonialism. The book first describes the history of the plastic waste trade, from toxic disasters in the 1970s and 1980s through the Basel Convention on the Control of Transboundary Movements of Hazardous Wastes and Their Disposal in 1989 through China’s 2018 implementation of a “National Sword” policy that effectively banned importation of plastic waste. From there, the authors explore both the legal trade in plastic waste and the underground illegal trade in waste, arguing that both lead to devastating impacts on ecosystems, workers, and communities in receiving countries and highlighting how countries that receive waste are often less equipped to process it than the countries that export waste. The last section of the book presents cases from countrieson the receiving end of the plastic waste trade, highlighting inherent problems from sociological and environmental justice perspectives.

Plastic and Polymer Industry by Region: Production, Consumption and Waste Management in the African Continent
by Ololade OlatunjiThis book addresses the need for a technical guided thought on production, consumption, and waste management of plastic and polymers in the African continent. Issues such as resource availability, processing technologies, plastic policies, and much more are covered in the book. While Africa is made up of several different countries which might be different from each other in many ways, these countries within the African continent have some commonalities such as region, some shared history, resources, and some shared policies through organizations such as the African Union, African Free trade Zone, and ECOWAS. With a population of over a billion, the African continent has become an attractive market for various businesses. Several publications in recent years have pushed for the advancement of the African continent toward increased manufacturing as a road to development. This inevitably includes the plastics and other polymers industry. Careful consideration must be taken to ensure that this growth will focus on more sustainable and greener manufacturing; otherwise, this anticipated growth in the plastics and polymer industry will only spell increased pollution and worsening of the environment.

Plastic: A Toxic Love Story
by Susan FreinkelPlastic built the modern world. Where would we be without bike helmets, baggies, toothbrushes, and pacemakers? But a century into our love affair with plastic, we’re starting to realize it’s not such a healthy relationship. Plastics draw on dwindling fossil fuels, leach harmful chemicals, litter landscapes, and destroy marine life. As journalist Susan Freinkel points out in this engaging and eye-opening book, we’re nearing a crisis point. We’ve produced as much plastic in the past decade as we did in the entire twentieth century. We’re drowning in the stuff, and we need to start making some hard choices. Freinkel gives us the tools we need with a blend of lively anecdotes and analysis. She combs through scientific studies and economic data, reporting from China and across the United States to assess the real impact of plastic on our lives. She tells her story through eight familiar plastic objects: comb, chair, Frisbee, IV bag, disposable lighter, grocery bag, soda bottle, and credit card. Her conclusion: we cannot stay on our plastic-paved path. And we don’t have to. Plastic points the way toward a new creative partnership with the material we love to hate but can’t seem to live without.

Plasticity and Pathology: On the Formation of the Neural Subject (Berkeley Forum In The Humanities Ser.)
by David Bates Nima BassiriTwo leading neuroscientists examine the current paradigm of the &“neural subject&” and what we can learn from neurological trauma, pathology, and adaption. With the rise of cognitive science and the revolution in neuroscience, the study of human subjects—thinking, feeling, acting individuals—ultimately focuses on the human brain. In both Europe and the United States, massive state-funded research is focused on mapping the brain in all its remarkable complexity. The metaphors employed are largely technological, using a diagram of synaptic connectivity as a path to understanding human behavior. But alongside this technologized discourse, we find another perspective, one that emphasizes the brain&’s essential plasticity, both in development and as a response to traumas such as strokes, tumors, or gunshot wounds. This collection of essays brings together a diverse range of scholars to investigate how the &“neural subject&” of the twenty-first century came to be. Taking approaches both historical and theoretical, they probe the possibilities and limits of neuroscientific understandings of human experience. Topics include landmark studies in the history of neuroscience, the relationship between neural and technological &“pathologies,&” and analyses of contemporary concepts of plasticity and pathology in cognitive neuroscience. Central to the volume is a critical examination of the relationship between pathology and plasticity. Because pathology is often the occasion for neural reorganization and adaptation, it exists not in opposition to the brain&’s &“normal&” operation but instead as something intimately connected to our ways of being and understanding.

Plasticity in the Central Nervous System: Learning and Memory
by James L. McGaugh Federico Bermúdez-Rattoni Roberto A. Prado-AlcaláCatalyzed by the development of new neurobiological and behavioral techniques as well as new conceptual and theoretical approaches to the study of the relationship between brain and behavior, research exploring brain functions enabling learning and memory has greatly accelerated in recent years. The chapters in this book reflect current theoretical approaches to the study of brain and memory and provide new insights concerning the cellular bases of memory and the differential involvement of brain systems in different forms of memory. By presenting up-to-date summaries of research investigating brain mechanisms underlying learning and memory, these chapters help to place current findings in appropriate theoretical context, and further stimulate research inquiry attempting to understand how the brain makes memory. Divided into three sections, coverage in this volume includes: * a discussion of pharmacological approaches to the study of brain and memory; * a review of experiments using a variety of techniques, including brain lesions, brain grafting, and electrophysiological recording to investigate the role of different brain regions in learning and memory; and * an examination of molecular analyses of events associated with memory formation.
Plasticity in the Life Sciences
by Antonine NicoglouAnalyzes the reasons why biologists have referred to and continue to refer to plasticity. Plasticity has become an important topic in biology, with some even wondering if it has now acquired the theoretical importance in biology that the concept of the gene enjoyed at the beginning of the last century. In this historical and epistemological study, philosopher Antonine Nicoglou shows how the recurrence of the general idea of plasticity—throughout the history of the life sciences—indicates its essential role in the way we think about life processes. Although plasticity has become a key element in new evolutionary thinking, she argues, its role in contemporary biology is also not insignificant. Rather, as mobilized in contemporary biology, plasticity most often seeks to account for the specific nature of living systems. The book is divided into two parts. The first takes up the history of plasticity from Aristotle to contemporary biology; the second part offers an original way of distinguishing between different phenomena described by “plasticity.” In the process, the author explores what has led some biologists to speak of plasticity as a way of overcoming genetic determinism.
Plasticity of Pressure-Sensitive Materials
by Andreas Öchsner Holm AltenbachClassical plasticity theory of metals is independent of the hydrostatic pressure. However if the metal contains voids or pores or if the structure is composed of cells, this classical assumption is no more valid and the influence of the hydrostatic pressure must be incorporated in the constitutive description. Looking at the microlevel, metal plasticity is connected with the uniform planes of atoms organized with long-range order. Planes may slip past each other along their close-packed directions. The result is a permanent change of shape within the crystal and plastic deformation. The presence of dislocations increases the likelihood of planes slipping. Nowadays, the theory of pressure sensitive plasticity is successfully applied to many other important classes of materials (polymers, concrete, bones etc. ) even if the phenomena on the micro-level are different to classical plasticity of metals. The theoretical background of this phenomenological approach based on observations on the macro-level is described in detail in this monograph and applied to a wide range of different important materials in the last part of this book.
Plasticity, Robustness, Development and Evolution
by Patrick Bateson Peter GluckmanHow do we understand and explain the apparent dichotomy between plasticity and robustness in the context of development? Can we identify these complex processes without resorting to 'either/or' solutions? Written by two leaders in the field, this is the first book to fully unravel the complexity of the subject, explaining that the epigenetic processes generating plasticity and robustness are in fact deeply intertwined. It identifies the different mechanisms that generate robustness and the various forms of plasticity, before considering the functional significance of the integrated mechanisms and how the component processes might have evolved. Finally, it highlights the ways in which epigenetic mechanisms could be instrumental in driving evolutionary change. Essential reading for biologists and psychologists interested in epigenetics and evolution, this book is also a valuable resource for biological anthropologists, sociobiologists, child psychologists and paediatricians.
