Book Description
Kermit the Frog famously said that it isn’t easy being green, and in Living at Micro Scale David Dusenbery shows that it isn’t easy being small—existing at the size of, say, a rotifer, a tiny multicellular animal just at the boundary between the visible and the microscopic. “Imagine,” he writes, “stepping off a curb and waiting a week for your foot to hit the ground.” At that scale, we would be small enough to swim inside the letter O in the word “rotifer.” What are the physical consequences of life at this scale? How do such organisms move, identify prey and predators and (if they’re so inclined) mates, signal to one another, and orient themselves? In clear and engaging prose, Dusenbery uses straightforward physics to demonstrate the constraints on the size, shape, and behavior of tiny organisms. While recounting the historical development of the basic concepts, he unearths a corner of microbiology rich in history, and full of lessons about how science does or does not progress. Marshalling findings from different fields to show why tiny organisms have some of the properties they are found to have, Dusenbery shows a science that doesn’t always move triumphantly forward, and is dependent to a great extent on accident and contingency.

Book Description
Our world is swarming with invisible organisms - bacteria and fungi that affect their hosts and environments in diverse ways. This text looks at the mysterious microscopic world of microbes and investigates how they behave, and why. It tells stories of how scientists have discovered the laws of behaviour of the world of microbes, including the principles of locomotion, navigation, survival, reproduction and communication. In addition, the text relates the behaviour of bacteria and other microbes to our more familiar world and shows their impact on our lives.

Book Description
Small-scale fisheries are a major source of food and employment around the world. Yet, many small-scale fishers work in conditions that are neither safe nor secure. Millions of them are poor, and often they are socially and politically marginalized. Macro-economic and institutional mechanisms are essential to address these poverty and vulnerability problems; however, interventions at the local community level are also necessary. This requires deep understanding of what poverty means to the fishers, their families and communities; how they cope with it; and the challenges they face to increase resiliency and improve their lives for the better. This book provides a global perspective, situating small-scale fisheries within the broad academic discourse on poverty, fisheries management and development. In-depth case studies from fifteen countries in Latin America, Europe, South and Southeast Asia, and sub-Saharan Africa, demonstrate the enormously complex ecological, economic, social, cultural and political contexts of this sector. Conclusions for policy-making, formulated as a joint statement by the authors, argue that fisheries development, poverty alleviation, and resource management must be integrated within a comprehensive governance approach that also looks beyond fisheries. The scientific editors, Svein Jentoft and Arne Eide, are both with the Norwegian College of Fishery Science, Faculty of Biosciences, Fisheries and Economics, University of Tromsø, Norway.

Book Description
In Life at Small Scale, noted biophysicist David B. Dusenbery describes how microbes obtain and use information from their environments to meet the fundamental challenges all organisms face - getting food, avoiding predators and competitors, and dispersing progeny. As Dusenbery demonstrates, these organisms are hardly as simple as is often presumed. Despite their size (or rather because of it), microbes develop some surprisingly complex behaviors, all in response to the physical demands of the worlds they inhabit. Thus the pages of this captivating, richly illustrated volume are filled with descriptions of organisms that have devised remarkably sophisticated, often bizarre ways of moving, navigating, communicating, eating, resisting enemies, besting rivals, and reproducing. From fungi that launch their spores as projectiles, to "magnetic" bacteria that align like compass needles with the Earth's magnetic field, to the microbes that disperse when we sneeze, Life at Small Scale introduces an intriguing cast of characters, exploring their lives and environments in exquisite detail. It also shows how knowledge gained from the study of microbes helps us understand life on human and global scales as well. Here then is definite proof: there is more to life than what meets the eye.

Book Description
Your concrete road map to rapidly grow your business and get your life back! Have you ever wanted to grow your business but held back because of fear that it would take over your life? As an owner, it’s all too common to feel you have to choose between your personal life and the success of your business. But the surprising truth is that the only way to truly scale and grow your company is to reduce its reliance on you. This means that, done right, scaling ensures that you can grow your business without sacrificing your life. Jeff Hoffman, a serial entrepreneur and former CEO in the Priceline (Priceline Yardsale) family of companies, and David Finkel, CEO of Maui Mastermind, a business coaching company with thousands of clients worldwide, offer a concrete road map for rapidly growing your business while also gaining more personal freedom. You’ll not only learn the best strategies to generate growth, but you’ll also get proven insider tips to sustain that growth through sound systems, empowered teams, and intelligent internal controls. Hoffman and Finkel will also show you how to overcome predictable obstacles in any pillar of your business—including sales, operations, and finance—with insight for building better lead-generation systems, managing cash flow, and retaining talent. You’ll learn how to: • Escape the Self-Employment Trap and build a business, not a job. • Systematize your business to reduce costs and increase capacity. • Ensure your company survives the “Hit by a Bus” test. • Uncover your company’s top leverage points (and execution strategies to implement what you discover). • Fund your growth with the seven cash flow commandments. • And much more.

Book Description
This book advances discussions of values in fisheries by showing the rich theoretical insights and connections possible when value is grounded in a multi-dimensional social well being approach. Questions of value have long been a central, if often unacknowledged, concern in maritime studies and in research on fisheries. Social scientists have looked at changing perceptions of value as coastal regions and fisheries have industrialized, economic interconnections have deepened, ecosystems have been depleted, shifts in population have occurred, and governance arrangements have been transformed. With a focus on the diverse ways in which small-scale fisheries are valued, the contributions to this volume address these and other themes through cases from numerous countries in Asia, Europe, and Latin America. “This volume provides a timely contribution to the development of new approaches that seek to capture the complexity of how fisheries can be understood beyond standard mo no-dimensional, and often economic, interpretations. Each chapter makes a clear and stand-alone contribution to conceptual and methodological advancement, and collectively these works cover a wide range of frameworks and schools of thought.” Dr Sarah Coulthard, Senior Lecturer in International Development, Northumbria University, UK “The list of contributing authors [is] impressive and covers a wide geographical range of illustrative examples, [which] helps to demonstrate the global value of small-scale fisheries.” Professor J. Allister McGregor, Professor in Political Economy, the University of Sheffield, UK
