R3,909 Discovery Miles 39 090 Ships in 12 - 19 working days

This book describes one of our closest relatives, the orangutan, and the only extant great ape in Asia. It is increasingly clear that orangutan populations show extensive variation in behavioral ecology, morphology, life history, and genes. Indeed, on the strength of the latest genetic and morphological evidence, it has been proposed that orangutans actually constitute two species which diverged more than a million years ago - one on the island of Sumatra the other on Borneo, with the latter comprising three subspecies.
This book has two main aims. The first is to carefully compare data from every orangutan research site, examining the differences and similarities between orangutan species, subspecies and populations. The second is to develop a theoretical framework in which these differences and similarities can be explained. To achieve these goals the editors have assembled the world's leading orangutan experts to rigorously synthesize and compare the data, quantify the similarities or differences, and seek to explain them.
Orangutans is the first synthesis of orangutan biology to adopt this novel, comparative approach. It analyses and compares the latest data, developing a theoretical framework to explain morphological, life history, and behavioral variation. Intriguingly, not all behavioral differences can be attributed to ecological variation between and within the two islands; relative rates of social learning also appear to have been influential. The book also emphasizes the crucial impact of human settlement on orangutans and looks ahead to the future prospects for the survival of critically endangered natural populations.

Elasticity and Geometry - From hair curls to the non-linear response of shells (Hardcover, New): Basile Audoly, Yves Pomeau Elasticity and Geometry - From hair curls to the non-linear response of shells (Hardcover, New)
Basile Audoly, Yves Pomeau
R5,303 Discovery Miles 53 030 Ships in 12 - 19 working days

We experience elasticity everywhere in daily life: in the straightening or curling of hairs, the irreversible deformations of car bodies after a crash, or the bouncing of elastic balls in ping-pong or soccer. The theory of elasticity is essential to the recent developments of applied and fundamental science, such as the bio-mechanics of DNA filaments and other macro-molecules, and the animation of virtual characters in computer graphics and materials science. In this book, the emphasis is on the elasticity of thin bodies (plates, shells, rods) in connection with geometry. It covers such topics as the mechanics of hairs (curled and straight), the buckling instabilities of stressed plates, including folds and conical points appearing at larger stresses, the geometric rigidity of elastic shells, and the delamination of thin compressed films. It applies general methods of classical analysis, including advanced nonlinear aspects (bifurcation theory, boundary layer analysis), to derive detailed, fully explicit solutions to specific problems. These theoretical concepts are discussed in connection with experiments. The book is self-contained. Mathematical prerequisites are vector analysis and differential equations. The book can serve as a concrete introduction to nonlinear methods in analysis.

Plasma Spectroscopy (Hardcover, New): Takashi Fujimoto Plasma Spectroscopy (Hardcover, New)
Takashi Fujimoto
R7,712 Discovery Miles 77 120 Ships in 12 - 19 working days

This book focuses on the characteristics of optical radiation, or a spectrum, emitted by various plasmas. In plasma, the same atomic species can produce quite different spectra, or colors depending on the nature of the plasma. This book gives a theoretical framework, by which a particular spectrum can be interpreted correctly and coherently. The uniqueness of the book lies in its comprehensive treatment of the intensity distribution of spectral lines and the population density distribution among the atomic levels, in plasma. It is intended to provide beginners with a good perspective of the field, laying out the physics in an extremely clear manner, starting from an elementary level. A very useful feature of the book is the asterisked sections and chapters which can be skipped by readers, who only wish to gain a quick and basic introduction to plasma spectroscopy. It will also be very useful to researchers working actively in the field, acting as a guide for carrying out experiments and interpreting experimental observations.

Bestselling historian William Dalrymple reinstates India as the great intellectual and philosophical superpower of Ancient Asia, tracing the cultural flow of its religion, science and mathematics.

For most of its modern history, India was fated to be on the receiving end of cultural influence from other civilisations. But this isn’t the complete story. A full millennium earlier, India’s major cultural exports – religion, art, technology, astronomy, mathematics, medicine, language and literature – were shaping civilisations, travelling as far as Afghanistan in the West and Japan in the East.

Out of India came pioneering merchants, astronomers and astrologers, scientists and mathematicians, surgeons and sculptors, as well as holy men, monks and missionaries. In The Golden Road, legendary historian William Dalrymple highlights India’s oft­forgotten position as a crucial economic and civilisational hub at the heart of the ancient and early medieval history of Eurasia.

From Angkor to Ayutthaya, The Golden Road traces the cultural flow of Indian religions, languages, artistic and architectural forms and mathematics throughout the world. In this groundbreaking tome, Dalrymple draws from a lifetime of scholarship to reinstate India as the great intellectual and philosophical superpower of ancient Asia.

What Tech Calls Thinking - An Inquiry into the Intellectual Bedrock of Silicon Valley (Paperback): Adrian Daub What Tech Calls Thinking - An Inquiry into the Intellectual Bedrock of Silicon Valley (Paperback)
Adrian Daub
R477 R448 Discovery Miles 4 480 Save R29 (6%) Ships in 10 - 15 working days

Adrian Daub’s What Tech Calls Thinking is a lively dismantling of the ideas that form the intellectual bedrock of Silicon Valley. Equally important to Silicon Valley’s world-altering innovation are the language and ideas it uses to explain and justify itself. And often, those fancy new ideas are simply old motifs playing dress-up in a hoodie. From the myth of dropping out to the war cry of “disruption,†Daub locates the Valley’s supposedly original, radical thinking in the ideas of Heidegger and Ayn Rand, the New Age Esalen Foundation in Big Sur, and American traditions from the tent revival to predestination. Written with verve and imagination, What Tech Calls Thinking is an intellectual refutation of Silicon Valley's ethos, pulling back the curtain on the self-aggrandizing myths the Valley tells about itself. FSG Originals × Logic dissects the way technology functions in everyday lives. The titans of Silicon Valley, for all their utopian imaginings, never really had our best interests at heart: recent threats to democracy, truth, privacy, and safety, as a result of tech’s reckless pursuit of progress, have shown as much. We present an alternate story, one that delights in capturing technology in all its contradictions and innovation, across borders and socioeconomic divisions, from history through the future, beyond platitudes and PR hype, and past doom and gloom. Our collaboration features four brief but provocative forays into the tech industry’s many worlds, and aspires to incite fresh conversations about technology focused on nuanced and accessible explorations of the emerging tools that reorganise and redefine life today.

Michael I. Posner
R2,549 Discovery Miles 25 490 Ships in 12 - 19 working days

The study of attention is central to psychology. In this work, Michael Posner, a pioneer in attention research, presents the science of attention in a larger social context, which includes our ability to voluntarily choose and act upon an object of thought. The volume is based on fifty years of research involving behavioral, imaging, developmental, and genetic methods. It describes three brain networks of attention that carry out the functions of obtaining and maintaining the alert state, orienting to sensory events, and regulating responses. The book ties these brain networks to anatomy, connectivity, development, and socialization and includes material on pathologies that involve attentional networks, as well as their role in education and social interaction.

Dopamine Nation - Why Our Addiction To Pleasure Is Causing Us Pain (Paperback): Anna Lembke Dopamine Nation - Why Our Addiction To Pleasure Is Causing Us Pain (Paperback)
Anna Lembke
R305 R258 Discovery Miles 2 580 Save R47 (15%) Ships in 5 - 10 working days

This book is about pleasure. It's also about pain. Most important, it's about how to find the delicate balance between the two, and why now more than ever finding balance is essential.

We're living in a time of unprecedented access to high-reward, high-dopamine stimuli: drugs, food, news, gambling, shopping, gaming, texting, sexting, Facebooking, Instagramming, YouTubing, tweeting... The increased numbers, variety, and potency is staggering. The smartphone is the modern-day hypodermic needle, delivering digital dopamine 24/7 for a wired generation. As such we've all become vulnerable to compulsive overconsumption.

In Dopamine Nation, Dr. Anna Lembke, psychiatrist and author, explores the exciting new scientific discoveries that explain why the relentless pursuit of pleasure leads to pain...and what to do about it. Condensing complex neuroscience into easy-to-understand metaphors, Lembke illustrates how finding contentment and connectedness means keeping dopamine in check. The lived experiences of her patients are the gripping fabric of her narrative. Their riveting stories of suffering and redemption give us all hope for managing our consumption and transforming our lives. In essence, Dopamine Nation shows that the secret to finding balance is combining the science of desire with the wisdom of recovery.

The volume begins with an overview of POGIL and a discussion of the science education reform context in which it was developed. Next, cognitive models that serve as the basis for POGIL are presented, including Johnstone's Information Processing Model and a novel extension of it.
Adoption, facilitation and implementation of POGIL are addressed next. Faculty who have made the transformation from a traditional approach to a POGIL student-centered approach discuss their motivations and implementation processes. Issues related to implementing POGIL in large classes are discussed and possible solutions are provided. Behaviors of a quality facilitator are presented and steps to create a facilitation plan are outlined.
Succeeding chapters describe how POGIL has been successfully implemented in diverse academic settings, including high school and college classrooms, with both science and non-science majors. The challenges for implementation of POGIL are presented, classroom practice is described, and topic selection is addressed. Successful POGIL instruction can incorporate a variety of instructional techniques. Tablet PC's have been used in a POGIL classroom to allow extensive communication between students and instructor. In a POGIL laboratory section, students work in groups to carry out experiments rather than merely verifying previously taught principles.
Instructors need to know if students are benefiting from POGIL practices. In the final chapters, assessment of student performance is discussed. The concept of a feedback loop, which can consist of self-analysis, student and peer assessments, and input from other instructors, and its importance in assessment is detailed. Datais provided on POGIL instruction in organic and general chemistry courses at several institutions. POGIL is shown to reduce attrition, improve student learning, and enhance process skills.

Brain Aromatase, Estrogens, and Behavior (Hardcover, New): Jacques Balthazart, Gregory Ball Brain Aromatase, Estrogens, and Behavior (Hardcover, New)
Jacques Balthazart, Gregory Ball
R4,386 Discovery Miles 43 860 Ships in 12 - 19 working days

It is well known that the class of steroid hormones known as estrogens have powerful effects on organs related to reproduction such as the uterus and the breast. What is less well known is that estrogens also profoundly modulate brain function and behavior. Estrogens, such as estradiol, can occur in brain as the result of ovarian secretion of the hormone into the blood that then finds its way to the brain. In male vertebrates, the testes secrete androgens, such as testosterone, into the blood and this class of steroid hormones can be converted into estrogens in the brain via the action of the enzyme aromatase which is expressed in the male brain in many species. Finally estradiol can be synthesized de novo from cholesterol as it has been shown in a variety of species that all the enzymes required to synthesize estrogens are expressed in the brain. This book collects chapters by experts in the field that considers, how estradiol is synthesized in the brain and what its effects are on a variety of behaviors. Special attention is paid to the enzyme aromatase that is distributed in discrete regions of the brain and is highly regulated in a sex specific and seasonal specific manner. Recently it has become clear that estrogens can act in the brain at two very different time scales, one is rather long lasting (days to weeks) and involves the modulation of gene transcription by the hormone-receptor complex. A second mode of action is much quicker and involves the action of estrogens on cell membranes that can result in effects on second messenger systems and ultimately behavior within minutes. Thus this book highlights novel views of estrogen action that are still under-appreciated namely that estrogens have significant effects on the male brain and that they can act on two very different times scales. This volume will be of interest to both basic researchers and clinicians interested in the action of estrogens.
