Book Description
Public transit is a powerful tool for addressing a huge range of urban problems, including traffic congestion and economic development as well as climate change. But while many people support transit in the abstract, it's often hard to channel that support into good transit investments. Part of the problem is that transit debates attract many kinds of experts, who often talk past each other. Ordinary people listen to a little of this and decide that transit is impossible to figure out. Jarrett Walker believes that transit can be simple, if we focus first on the underlying geometry that all transit technologies share. In Human Transit, Walker supplies the basic tools, the critical questions, and the means to make smarter decisions about designing and implementing transit services. Human Transit explains the fundamental geometry of transit that shapes successful systems; the process for fitting technology to a particular community; and the local choices that lead to transit-friendly development. Whether you are in the field or simply a concerned citizen, here is an accessible guide to achieving successful public transit that will enrich any community.

The Multi-Agent Transport Simulation MATSim

The Multi-Agent Transport Simulation MATSim PDF Author: Andreas Horni
Publisher: Ubiquity Press
ISBN: 190918876X
Category : Technology & Engineering
Languages : en
Pages : 620

Book Description
The MATSim (Multi-Agent Transport Simulation) software project was started around 2006 with the goal of generating traffic and congestion patterns by following individual synthetic travelers through their daily or weekly activity programme. It has since then evolved from a collection of stand-alone C++ programs to an integrated Java-based framework which is publicly hosted, open-source available, automatically regression tested. It is currently used by about 40 groups throughout the world. This book takes stock of the current status. The first part of the book gives an introduction to the most important concepts, with the intention of enabling a potential user to set up and run basic simulations. The second part of the book describes how the basic functionality can be extended, for example by adding schedule-based public transit, electric or autonomous cars, paratransit, or within-day replanning. For each extension, the text provides pointers to the additional documentation and to the code base. It is also discussed how people with appropriate Java programming skills can write their own extensions, and plug them into the MATSim core. The project has started from the basic idea that traffic is a consequence of human behavior, and thus humans and their behavior should be the starting point of all modelling, and with the intuition that when simulations with 100 million particles are possible in computational physics, then behavior-oriented simulations with 10 million travelers should be possible in travel behavior research. The initial implementations thus combined concepts from computational physics and complex adaptive systems with concepts from travel behavior research. The third part of the book looks at theoretical concepts that are able to describe important aspects of the simulation system; for example, under certain conditions the code becomes a Monte Carlo engine sampling from a discrete choice model. Another important aspect is the interpretation of the MATSim score as utility in the microeconomic sense, opening up a connection to benefit cost analysis. Finally, the book collects use cases as they have been undertaken with MATSim. All current users of MATSim were invited to submit their work, and many followed with sometimes crisp and short and sometimes longer contributions, always with pointers to additional references. We hope that the book will become an invitation to explore, to build and to extend agent-based modeling of travel behavior from the stable and well tested core of MATSim documented here.

Lone Survivors

Lone Survivors PDF Author: Chris Stringer
Publisher: Macmillan
ISBN: 1429973447
Category : Science
Languages : en
Pages : 346

Book Description
A top researcher proposes a controversial new theory of human evolution in a book “combining the thrill of a novel with a remarkable depth of perspective” (Nature). In this groundbreaking and engaging work of science, world-renowned paleoanthropologist Chris Stringer sets out a new theory of humanity’s origin, challenging both the multiregionalists (who hold that modern humans developed from ancient ancestors in different parts of the world) and his own “out of Africa” theory, which maintains that humans emerged rapidly in one small part of Africa and then spread to replace all other humans within and outside the continent. Stringer’s new theory, based on archeological and genetic evidence, holds that distinct humans coexisted and competed across the African continent—exchanging genes, tools, and behavioral strategies. Stringer draws on analyses of old and new fossils from around the world, DNA studies of Neanderthals (using the full genome map) and other species, and recent archeological digs to unveil his new theory. He shows how the most sensational recent fossil findings fit with his model, and he questions previous concepts (including his own) of modernity and how it evolved. With photographs included, Lone Survivors will be the definitive account of who and what we were—and will change perceptions about our origins and about what it means to be human. “An essential book for anyone interested in psychology, sociology, anthropology, human evolution, or the scientific process.” —Library Journal “Highlights just how many tantalizing discoveries and analytical advances have enriched the field in recent years.” —Literary Review

Guidelines for the Humane Transportation of Research Animals

Guidelines for the Humane Transportation of Research Animals PDF Author: National Research Council
Publisher: National Academies Press
ISBN: 030916477X
Category : Science
Languages : en
Pages : 164

Book Description
Arranging the transportation of animals at research facilities is often an ordeal. There is a confusing patchwork of local, national, and international regulations; a perceived lack of high-quality shipping services; a dearth of science-based good practices; and a lack of biosafety standards. It's a challenge â€"and an impediment to biomedical research. Guidelines for the Humane Transportation of Research Animals identifies the current problems encountered in the transportation of research animals and offers recommendations aimed at local and federal officials to rectify these problems. This book also includes a set of good practices based on the extensive body of literature on transportation of agricultural animals, universal concepts of physiology, and a scientific understanding of species-specific needs and differences. Good practices were developed by the committee to address thermal environment, space requirements, food and water requirements, social interaction, monitoring of transportation, emergency procedures, personnel training, and biosecurity. Guidelines for the Humane Transportation of Research Animals is an essential guide for all researchers, animal care technicians, facilities managers, administrators, and animal care and use committees at research institutions.

The True Meaning of Smekday

The True Meaning of Smekday PDF Author: Adam Rex
Publisher: Little, Brown Books for Young Readers
ISBN: 1484731689
Category : Juvenile Fiction
Languages : en
Pages : 287

Book Description
The hilarious, genre-bending novel from bestselling author Adam rex that inspired the blockbuster feature film Home -- fully illustrated with "photos," drawings, newspaper clippings, and comics sequences. When twelve-year-old Gratuity ("Tip") Tucci is assigned to write five pages on "The True Meaning of Smekday" for the National Time Capsule contest, she's not sure where to begin; when her mom started telling everyone about the messages aliens were sending through a mole on the back of her neck? Maybe on Christmas Eve, when huge bizarre spaceships descended on Earth and the aliens -- called Boov -- abducted her mother? Or when the Boov declared Earth a colony, renamed it "Smekland" (in honor of glorious Captain Smek), and forced all Americans to relocate to Florida via rocketpod? In any case, Gratuity's story is much, much bigger than the assignment. It involves her unlikely friendship with a renegade Boov mechanic named J.Lo; a futile journey south to find Gratuity's mother at the Happy Mouse Kingdom; a cross-country road trip in a hovercar called Slushious; and an outrageous plan to save the Earth from yet another alien invasion.

Regulation of Tissue Oxygenation, Second Edition

Regulation of Tissue Oxygenation, Second Edition PDF Author: Roland N. Pittman
Publisher: Biota Publishing
ISBN: 1615047212
Category : Medical
Languages : en
Pages : 117

Book Description
This presentation describes various aspects of the regulation of tissue oxygenation, including the roles of the circulatory system, respiratory system, and blood, the carrier of oxygen within these components of the cardiorespiratory system. The respiratory system takes oxygen from the atmosphere and transports it by diffusion from the air in the alveoli to the blood flowing through the pulmonary capillaries. The cardiovascular system then moves the oxygenated blood from the heart to the microcirculation of the various organs by convection, where oxygen is released from hemoglobin in the red blood cells and moves to the parenchymal cells of each tissue by diffusion. Oxygen that has diffused into cells is then utilized in the mitochondria to produce adenosine triphosphate (ATP), the energy currency of all cells. The mitochondria are able to produce ATP until the oxygen tension or PO2 on the cell surface falls to a critical level of about 4–5 mm Hg. Thus, in order to meet the energetic needs of cells, it is important to maintain a continuous supply of oxygen to the mitochondria at or above the critical PO2 . In order to accomplish this desired outcome, the cardiorespiratory system, including the blood, must be capable of regulation to ensure survival of all tissues under a wide range of circumstances. The purpose of this presentation is to provide basic information about the operation and regulation of the cardiovascular and respiratory systems, as well as the properties of the blood and parenchymal cells, so that a fundamental understanding of the regulation of tissue oxygenation is achieved.

Humans Are Underrated

Humans Are Underrated PDF Author: Geoff Colvin
Publisher: Penguin
ISBN: 0698153650
Category : Business & Economics
Languages : en
Pages : 258

Book Description
As technology races ahead, what will people do better than computers? What hope will there be for us when computers can drive cars better than humans, predict Supreme Court decisions better than legal experts, identify faces, scurry helpfully around offices and factories, even perform some surgeries, all faster, more reliably, and less expensively than people? It’s easy to imagine a nightmare scenario in which computers simply take over most of the tasks that people now get paid to do. While we’ll still need high-level decision makers and computer developers, those tasks won’t keep most working-age people employed or allow their living standard to rise. The unavoidable question—will millions of people lose out, unable to best the machine?—is increasingly dominating business, education, economics, and policy. The bestselling author of Talent Is Overrated explains how the skills the economy values are changing in historic ways. The abilities that will prove most essential to our success are no longer the technical, classroom-taught left-brain skills that economic advances have demanded from workers in the past. Instead, our greatest advantage lies in what we humans are most powerfully driven to do for and with one another, arising from our deepest, most essentially human abilities—empathy, creativity, social sensitivity, storytelling, humor, building relationships, and expressing ourselves with greater power than logic can ever achieve. This is how we create durable value that is not easily replicated by technology—because we’re hardwired to want it from humans. These high-value skills create tremendous competitive advantage—more devoted customers, stronger cultures, breakthrough ideas, and more effective teams. And while many of us regard these abilities as innate traits—“he’s a real people person,” “she’s naturally creative”—it turns out they can all be developed. They’re already being developed in a range of far-sighted organizations, such as: • the Cleveland Clinic, which emphasizes empathy training of doctors and all employees to improve patient outcomes and lower medical costs; • the U.S. Army, which has revolutionized its training to focus on human interaction, leading to stronger teams and greater success in real-world missions; • Stanford Business School, which has overhauled its curriculum to teach interpersonal skills through human-to-human experiences. As technology advances, we shouldn’t focus on beating computers at what they do—we’ll lose that contest. Instead, we must develop our most essential human abilities and teach our kids to value not just technology but also the richness of interpersonal experience. They will be the most valuable people in our world because of it. Colvin proves that to a far greater degree than most of us ever imagined, we already have what it takes to be great.

The Book of Humans: A Brief History of Culture, Sex, War, and the Evolution of Us

The Book of Humans: A Brief History of Culture, Sex, War, and the Evolution of Us PDF Author: Adam Rutherford
Publisher: The Experiment, LLC
ISBN: 1615195327
Category : Science
Languages : en
Pages : 303

Book Description
“Rutherford describes [The Book of Humans] as being about the paradox of how our evolutionary journey turned ‘an otherwise average ape’ into one capable of creating complex tools, art, music, science, and engineering. It’s an intriguing question, one his book sets against descriptions of the infinitely amusing strategies and antics of a dizzying array of animals.”—The New York Times Book Review Publisher’s Note: The Book of Humans was previously published in hardcover as Humanimal. In this new evolutionary history, geneticist Adam Rutherford explores the profound paradox of the human animal. Looking for answers across the animal kingdom, he finds that many things once considered exclusively human are not: We aren’t the only species that “speaks,” makes tools, or has sex outside of procreation. Seeing as our genome is 98 percent identical to a chimpanzee’s, our DNA doesn’t set us far apart, either. How, then, did we develop the most complex culture ever observed? The Book of Humans proves that we are animals indeed—and reveals how we truly are extraordinary.
