Wat Moet Ons Met Ons Kerk Doen? is 'n poging om te probeer verstaan waar ons as Afrikaners teologies vandaan kom, watter kragte en magte ons en ons Kerk gevorm het en hoe ons Kerk tans daar uitsien.
Die N.G.Kerk was 'n belangrike en rigtinggewende rolspele in die opheffing van die Afrikaner na die Britse vergrype tydens en na die Tweede Vryheidsoorlog. Tans word die N.G.Kerk ervaar as 'n instansie wat ongevoelig teenoor die geestelike behoeftes van haar lidmate staan.

WHEN we eat may be as important as WHAT we eat.
Like most people, you probably wake up, get hungry for meals and doze off in bed around the same time every day. If you’ve ever experienced jet lag or pulled an all-nighter, you know that this schedule can easily be thrown off kilter. But for some people, that imbalance—difficulty sleeping at night, hunger at odd times, or sudden fatigue at noon—is a constant. If you're one of those people, Dr. Satchin Panda, one of the leading researchers on circadian rhythms, has a plan to reset your body clock.
Beginning with an in-depth explanation of the circadian clock—why it’s important, how it works, and how to know it isn’t working—The Circadian Code outlines lifestyle changes to make to get back on track. It's a concrete plan to enhance weight loss, improve sleep, optimize exercise, and manage technology so that it doesn’t interfere with your body’s natural rhythm. Dr. Panda’s life changing methods show you how to prevent and reverse ailments like diabetes, cancer, and dementia, as well as microbiome conditions like acid reflux, heartburn, and irritable bowel disease.
Humanity has often found itself on the precipice. We've survived and
thrived because we've never stopped moving...
At a time when science can seem complex and remote, it has a greater
impact on our lives, and to the future of our planet, than ever before.
It really matters that its discoveries and truths should be clearly and
widely communicated. That its enemies, from the malicious to the
muddled, the self-deluding to the selfinterested, be challenged and
exposed. That science should be brought out of the laboratory, taken
into the corridors of power and defended in the maelstrom of popular
culture. No one does this better than Richard Dawkins.
'Richard Dawkins is a thunderously gifted science writer.' Sunday Times Including conversations with Neil DeGrasse Tyson, Steven Pinker, Matt Ridley and more, this is an essential guide to the most exciting ideas of our time and their proponents from our most brilliant science communicator.

'Michael Spitzer has pulled off the impossible: a Guns, Germs and Steel for music' Daniel Levitin 165 million years ago saw the birth of rhythm. 66 million years ago was the first melody. 40 thousand years ago Homo sapiens created the first musical instrument. Today music fills our lives. How we have created, performed and listened to this music throughout history has defined what our species is and how we understand who we are. Yet music is an overlooked part of our origin story. The Musical Human takes us on an exhilarating journey across the ages - from Bach to BTS and back - to explore the vibrant relationship between music and the human species. With insights from a wealth of disciplines, world-leading musicologist Michael Spitzer renders a global history of music on the widest possible canvas, looking at music in our everyday lives; music in world history; and music in evolution, from insects to apes, humans to AI. Through this journey we begin to understand how music is central to the distinctly human experiences of cognition, feeling and even biology, both widening and closing the evolutionary gaps between ourselves and animals in surprising ways. The Musical Human boldly puts the case that music is the most important thing we ever did; it is a fundamental part of what makes us human.
Measuring Behaviour is the established go-to text for anyone interested in scientific methods for studying the behaviour of animals or humans. It is widely used by students, teachers and researchers in a variety of fields, including biology, psychology, the social sciences and medicine. This new fourth edition has been completely rewritten and reorganised to reflect major developments in how behavioural studies are conducted. It includes new sections on the replication crisis, covering Open Science initiatives such as preregistration, as well as fully up-to-date information on the use of remote sensors, big data and artificial intelligence in capturing and analysing behaviour. The sections on the analysis and interpretation of data have been rewritten to align with current practices, with advice on avoiding common pitfalls. Although fully revised and revamped, this new edition retains the simplicity, clarity and conciseness that have made Measuring Behaviour a classic since the first edition appeared more than 30 years ago.
Charles Krebs' best-selling majors-level text approaches ecology as a series of problems that are best understood by evaluating empirical evidence through data analysis and application of quantitative reasoning. No other text presents analytical, quantitative, and statistical ecological information in an equally accessible style for students. Reflecting the way ecologists actually practice, the new edition emphasizes the role of experiments in testing ecological ideas and discusses many contemporary and controversial problems related to distribution and abundance. Ecology: The Experimental Analysis of Distribution and Abundance, Sixth Edition builds on a clear writing style, historical perspective, and emphasis on data analysis with an updated, reorganized discussion of key topics and two new chapters on climate change and animal behavior. Key concepts and key terms are now included at the beginning of each chapter to help students focus on what is most important within each chapter, mathematical analyses are broken down step by step in a new feature called "Working with the Data," concepts are reinforced throughout the text with examples from the literature, and end-of-chapter questions and problems emphasize application.
An engaging and thrilling tour of the new frontiers in mycology-from ecology to fermentation to medicine-introducing the reader to the fascinating characters involved in the fungal Renaissance. Fungi are fundamental to life. As decomposers, they are critical to the formation and sustenance of soils and ecosystems. As endlessly innovative chemists, they devise and secrete enzymes that can break down a vast variety of materials, mitigate bacterial and viral infections, and interact-for better or worse-with the bodies and brains of animals that consume their fruiting bodies, commonly called mushrooms. Given their ubiquity and utility, it's no surprise that humans have deep cultural connections to fungi and mushrooms, even while they have remained both understudied by institutional science and misunderstood by the general populace. But an emerging mycological vanguard is reaching maturity, exploring and advocating for fungi's capacity to remediate contaminated landscapes and waterways, provide food and medicine, and demonstrate how humans might live in equitable and sustainable accord with nature and one another. This diverse cadre of growers, independent researchers, ecologists, entrepreneurs, and amateur enthusiasts is also scrambling to seize on rising demand for specialty mushrooms in culinary and medicinal markets, advance burgeoning fields of 'applied mycology,' and center conversations about social justice and sustainability. In In Search of Mycotopia, Doug Bierend introduces readers to an incredible and oft-overlooked kingdom of life and the potential it holds for our future, by way of the weird and wonderful communities of citizen scientists and microbe devotees working on the fungal frontier. Together they form a picture of the modern mycological movement, which sees these organisms as teachers, partners, and sources of wisdom that offer ways and means for creating a better world.
Why are we influenced by the behaviour of complete strangers? Why does the brain register similar pleasure when I perceive something as 'fair' or when I eat chocolate? Why can we be so profoundly hurt by bereavement? What are the evolutionary benefits of these traits? The young discipline of 'social cognitive neuroscience' has been exploring this fascinating interface between brain science and human behaviour since the late 1990s. Now one of its founding pioneers, Matthew D. Lieberman, presents the discoveries that he and fellow researchers have made. Using fMRI scanning and a range of other techniques, they have been able to see that the brain responds to social pain and pleasure the same way as physical pain and pleasure; and that unbeknown to ourselves, we are constantly 'mindreading' other people so that we can fit in with them. It is clear that our brains are designed respond to and be influenced by others. For good evolutionary reasons, he argues, we are wired to be social. The implications are numerous and profound. Do we have to rethink what we understand by identity, and free will? How can managers improve the way their teams relate and perform? Could we organize large social institutions in ways that would work far better? And could there be whole new methods of education?
The increased and widespread availability of large network data resources in recent years has resulted in a growing need for effective methods for their analysis. The challenge is to detect patterns that provide a better understanding of the data. However, this is not a straightforward task because of the size of the data sets and the computer power required for the analysis. The solution is to devise methods for approximately answering the questions posed, and these methods will vary depending on the data sets under scrutiny. This cutting-edge text introduces biological concepts and biotechnologies producing the data, graph and network theory, cluster analysis and machine learning, before discussing the thought processes and creativity involved in the analysis of large-scale biological and medical data sets, using a wide range of real-life examples. Bringing together leading experts, this text provides an ideal introduction to and insight into the interdisciplinary field of network data analysis in biomedicine.
For Mark Solms, one of the boldest thinkers in contemporary neuroscience, discovering how consciousness comes about has been a lifetime's quest. Scientists consider it the "hard problem" because it seems an impossible task to understand why we feel a subjective sense of self and how it arises in the brain. Venturing into the elementary physics of life, Solms has now arrived at an astonishing answer. In The Hidden Spring, he brings forward his discovery in accessible language and graspable analogies. Solms is a frank and fearless guide on an extraordinary voyage from the dawn of neuropsychology and psychoanalysis to the cutting edge of contemporary neuroscience, adhering to the medically provable. But he goes beyond other neuroscientists by paying close attention to the subjective experiences of hundreds of neurological patients, many of whom he treated, whose uncanny conversations expose much about the brain's obscure reaches. Most importantly, you will be able to recognize the workings of your own mind for what they really are, including every stray thought, pulse of emotion, and shift of attention. The Hidden Spring will profoundly alter your understanding of your own subjective experience.
Longlisted for the National Book Award for Nonfiction and A New York Times Notable Book of 2018. Our understanding of the 'tree of life', with powerful implications for human genetics, human health and our own human nature, has recently completely changed. This book is about a new method of telling the story of life on earth - through molecular phylogenetics. It involves a fairly simple method - the reading of the deep history of life by looking at the variation in protein molecules found in living organisms. For instance, we now know that roughly eight per cent of the human genome arrived not through traditional inheritance from directly ancestral forms, but sideways by viral infection. In The Tangled Tree, acclaimed science writer David Quammen chronicles these discoveries through the lives of the researchers who made them - such as Carl Woese, the most important little-known biologist of the twentieth century; Lynn Margulis, the notorious maverick whose wild ideas about 'mosaic' creatures proved to be true; and Tsutomu Wantanabe, who discovered that the scourge of antibiotic-resistant bacteria is a direct result of horizontal gene transfer, bringing the deep study of genome histories to bear on a global crisis in public health. Quammen explains how molecular studies of evolution have brought startling recognitions about the tangled tree of life - including where we humans fit into it. Thanks to new technologies, we now have the ability to alter even our genetic composition - through sideways insertions, as nature has long been doing. The Tangled Tree is a brilliant exploration of our transformed understanding of evolution and of life's history itself.
When the famous South African fish scientist Professor JLB Smith published Old Fourlegs - The Story of the Coelacanth in 1956 he created an international sensation. After all, this 400-million-year-old fish, known only from fossil remains, was thought to have become extinct around 66 million years ago! JLB Smith’s dramatic account of the discovery of the first and second coelacanths in 1938 and 1952 turned him into a cult figure and put South African science on the world map. His book was eventually published in six English editions and translated into nine foreign languages.
Mike Bruton’s The Annotated Old Fourlegs includes a facsimile reprint of the original book, to which he has added notes and images in the margins that provide an interesting and revealing commentary on Smith’s text, as well as new introductory and explanatory chapters that bring the coelacanth story up to date.
In The Power of Habit , award-winning New York Times business
reporter Charles Duhigg takes us to the thrilling edge of scientific
discoveries that explain why habits exist and how they can be changed.
Motion processing is an essential piece of the complex brain machinery that allows us to reconstruct the 3D layout of objects in the environment, to break camouflage, to perform scene segmentation, to estimate the ego movement, and to control our action. Although motion perception and its neural basis have been a topic of intensive research and modeling the last two decades, recent experimental evidences have stressed the dynamical aspects of motion integration and segmentation. This book presents the most recent approaches that have changed our view of biological motion processing. These new experimental evidences call for new models emphasizing the collective dynamics of large population of neurons rather than the properties of separate individual filters. Chapters will stress how the dynamics of motion processing can be used as a general approach to understand the brain dynamics itself.
"Fascinating and exhilarating-Sean B. Carroll at his very best."-Bill Bryson, author of The Body: A Guide for Occupants From acclaimed writer and biologist Sean B. Carroll, a rollicking, awe-inspiring story of the surprising power of chance in our lives and the world Why is the world the way it is? How did we get here? Does everything happen for a reason or are some things left to chance? Philosophers and theologians have pondered these questions for millennia, but startling scientific discoveries over the past half century are revealing that we live in a world driven by chance. A Series of Fortunate Events tells the story of the awesome power of chance and how it is the surprising source of all the beauty and diversity in the living world. Like every other species, we humans are here by accident. But it is shocking just how many things-any of which might never have occurred-had to happen in certain ways for any of us to exist. From an extremely improbable asteroid impact, to the wild gyrations of the Ice Age, to invisible accidents in our parents' gonads, we are all here through an astonishing series of fortunate events. And chance continues to reign every day over the razor-thin line between our life and death. This is a relatively small book about a really big idea. It is also a spirited tale. Drawing inspiration from Monty Python, Kurt Vonnegut, and other great thinkers, and crafted by one of today's most accomplished science storytellers, A Series of Fortunate Events is an irresistibly entertaining and thought-provoking account of one of the most important but least appreciated facts of life.
Written for all therapists who want to understand this groundbreaking theory as it might actually show up in their day-to-day practice, this book offers a comprehensive approach to polyvagal-informed intervention.
