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.

Hierdie is 'n moet-lees boek vir:

• Lidmate wat ons Kerk graag wil help om 'n gesonde, geestelike tuiste vir Suid-Afrikaners van die 21ste eeu te bied.
• Die klakkelose napraters van die dogma wat dink ons Kerk is steeds op die regte pad.
• Die plastiekpredikante van die radio en televisie wat met eentonige reëlmaat soetsappige, sogenaamd godsdienstige, pleisters plak.
• Diegene wat reeds ons Kerk tot die ashoop van die geloof verdoem het.

A groundbreaking exploration of the neuroscience of spirituality and a bold new paradigm for health, healing, and resilience.

Whether it's meditation or a walk in nature, reading a sacred text or saying a prayer, there are many ways to tap into a heightened awareness of the world around us and our place in it. Lisa Miller draws on decades of clinical experience and award-winning research to show that humans are universally equipped with this capacity for spirituality, and that our brains become more resilient and robust as a result of it. Bringing scientific rigour to the most intangible aspect of our lives, Miller's counterintuitive findings reveal the measurable positive effects of spirituality: for better decision-making, a healthier brain and an inspired life.

Brimming with inspiration and compassion, this landmark book revolutionizes our understanding of spirituality, mental health and how to find meaning and purpose in life.

A true-life scientific adventure story, this thrilling book takes the reader deep into South African caves to discover fossil remains that compel a monumental reframing of the human family tree.

In the summer of 2022, Lee Berger lost 50 pounds in order to wriggle though impossibly small openings in the Rising Star cave complex in South Africa—spaces where his team has been unearthing the remains of Homo naledi, a proto-human likely to have coexisted with Homo sapiens some 250,000 years ago. The lead researcher on the site, still Berger had never made his way into the dark, cramped, dangerous underground spaces where many of the naledi fossils had been found. Now he was ready to do so.

Once inside the cave, Berger made shocking new discoveries that expand our understanding of this early hominid—discoveries that stand to alter our fundamental understanding of what makes us human. So what does it all mean?

Join Berger on the adventure of a lifetime as he explores the Rising Star cave system and begins the complicated process of explaining these extraordinary finds—finds that force a rethinking of human evolution, and discoveries that Berger calls “the Rosetta stone of the human mind.”

The human pathogens Neisseria meningitidis and Neisseria gonorrhoeae are exquisitely adapted to life within the human mucosa, their only natural niche. N. meningitidis is the causative agent of rapidly transmissible meningitis and septic shock. Vaccines developed to control this pathogen can be rendered ineffective by the pathogen's ability to undergo antigenic variation. In contrast, there are no current vaccination prospects for N. gonorrhoeae, the causative agent of sexually transmitted gonorrhoea. Historically, infections caused by N. gonorrhoeae were treated with antibiotics. However, the recent advent of new strains with resistance to all known antibiotics is causing such treatment regimes to fail, necessitating the need for new and more effective control strategies. In this book, leading Neisseria authorities review the most important research on pathogenic Neisseria to provide a timely overview of the field. The topics covered include: the link between pathogenesis and important metabolic pathways * vaccine development * antibiotic resistance * transcriptomics of regulatory networks * regulatory small RNAs * interactions with neutrophils * advances in humanized mouse models. An essential guide for research scientists, advanced students, clinicians, and other professionals working with Neisseria, the book is a recommended text for all microbiology libraries.

'Motor Cognition' describes the field of motor cognition - one to which the author's contribution has been seminal. The book examines how the motor actions we perform and watch others perform play a pivotal role in the construction of the 'self' - our ability to acknowledge and recognise our own identity.

Rapid advances in high-throughput genome sequencing technologies foreshadow a near-future in which millions of individuals will gain affordable access to their complete genome sequence. This promises to offer unprecedented insights into the fundamental biological nature of ourselves and our species: where we came from, how we begin our lives, how we develop and grow, how we interact with our environment, how we get sick, how we get well, and how we age. Personal genomics is an essential component of the inevitable transition towards personalized health and medicine. As the medical establishment begins to explore and evaluate the role of personal genomics in health and medicine, both clinicians and patients alike will gain from becoming well versed in both the power and the pitfalls of personal genomic information. Furthermore, it is likely that all students of the biomedical sciences will soon be required to gain crucial understanding in the emerging field of personal genomics. Exploring Personal Genomics provides a novel, inquiry-based approach to the understanding and interpretation of the practical, medical, physiological, and societal aspects of personal genomic information. The material is presented in two parts: the first provides readers of all backgrounds with a fundamental understanding of the biology of human genomes, information on how to obtain and understand digital representations of personal genomic data, tools and techniques for exploring the personal genomics of ancestry and genealogy, discovery and interpretation of genetic trait associations, and the role of personal genomics in drug response. The second part offers more advanced readers an understanding of the science, tools, and techniques for investigating interactions between a personal genome and the environment, connecting DNA to physiology, and assessing rare variants and structural variation. This book aims to support undergraduate and graduate studies in medicine, genetics, molecular biology, and bioinformatics. Additionally, the design of the content is such that medical practitioners, professionals working in the biomedical sciences or related fields, and motivated lay individuals interested in exploring their personal genetic data should find it relevant and approachable.

The Arctic Tundra and adjacent Boreal Forest or Taiga support the most cold-adapted flora and fauna on Earth. The evolutionary capacity of both plants and animals to adapt to these thermally limiting conditions has always attracted biological investigation and is a central theme of this book. How the polar biota will adapt to a warmer world is creating significant and renewed interest in this habitat. The Arctic has always been subject to climatic fluctuation and the polar biota has successfully adapted to these changes throughout its evolutionary history. Whether or not climatic warming will allow the Boreal Forest to advance onto the treeless Tundra is one of the most tantalizing questions that can be asked today in relation to terrestrial polar biology. Tundra-Taiga Biology provides a circum-polar perspective of adaptation to low temperatures and short growing seasons, together with a history of climatic variation as it has affected the evolution of terrestrial life in the Tundra and the adjacent forested Taiga. It will appeal to researchers new to the field and to the many students, professional ecologists and conservation practitioners requiring a concise but authoritative overview of the biome. Its accessibility also makes it suitable for undergraduate and graduate students taking courses in tundra, taiga, and arctic ecology.

Because of their vital role in the emergence of humanity, tools and their uses have been the focus of considerable worldwide study. This volume brings together international research on the use of tools among primates and both prehistoric and modern humans. The book represents leading work being done by specialists in anatomy, neurobiology, prehistory, ethnology, and primatology. Whether composed of stone, wood, or metal, tools are a prolongation of the arm that acquire precision through direction by the brain. The same movement, for example, may have been practiced by apes and humans, but the resulting action varies according to the extended use of the tool. It is therefore necessary, as the contributors here make clear, to understand the origin of tools, and also to describe the techniques involved in their manipulation, and the possible uses of unknown implements. Comparison of the techniques of chimpanzees with those of prehistoric and modern peoples has made it possible to appreciate the common aspects and to identify the differences. The transmission of ability has also been studied in the various relevant societies: chimpanzees in their natural habitat and in captivity, hunter-gatherers, and workmen in prehistoric and in modern times. In drawing together much valuable research, this work will be an important and timely resource for social and behavioral psychologists, anthropologists, paleontologists, and animal behaviorists.

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.

This volume presents state-of-the-art empirical studies working in a paradigm that has become known as human behavioral ecology. The emergence of this approach in anthropology was marked by publication by Aldine in 1979 of an earlier collection of studies edited by Chagnon and Irons entitled Evolutionary Biology and Human Social Behavior: An Anthropological Perspective. During the two decades that have passed since then, this innovative approach has matured and expanded into new areas that are explored here.

The book opens with an introductory chapter by Chagnon and Irons tracing the origins of human behavioral ecology and its subsequent development. Subsequent chapters, written by both younger scholars and established researchers, cover a wide range of societies and topics organ-ized into six sections. The first section includes two chapters that provide historical background on the development of human behavioral ecology and com-pare it to two complementary approaches in the study of evolution and human behavior, evolutionary psychology, and dual inheritance theory. The second section includes five studies of mating efforts in a variety of societies from South America and Africa. The third section covers parenting, with five studies on soci-eties from Africa, Asia, and North America. The fourth section breaks somewhat with the tradition in human behavioral ecology by focusing on one particularly problematic issue, the demographic transition, using data from Europe, North America, and Asia. The fifth section includes studies of cooperation and helping behaviors, using data from societies in Micronesia and South America. The sixth and final section consists of a single chapter that places the volume in a broader critical and comparative context.

The contributions to this volume demonstrate, with a high degree of theoretical and methodological sophistication--the maturity and freshness of this new paradigm in the study of human behavior. The volume will be of interest to anthropologists and other professions working on the study of cross-cultural human behavior.

Studies of insect nervous systems have made an immense contribution to our understanding of how a brain works and the way that the connections between constituent neurons are formed during development, For the first time these studies are brought together in The neurobiology of an insect brain, a personal account by a leading experimental neurobiologist and zoologist. By concentrating largely on one insect, the locust, this book unravels the mechanisms by which a brain integrates the vast array of sensory information to generate appropriate movements and behaviour. It first describes the basic structure of an insect brain and how this complex structure is formed during embryonic development. The cellular properties of the different types of neurons, and the way they are altered by neurosecretions are then analysed with respect to the integrative actions of these neurons during behaviour. Finally, the various movements that an insect performs are investigated at the cellular level to illustrate particular features of the integrative processing. Throughout, the book emphasises how knowledge of these simpler nervous systems contributes to our understanding of more complex brains, and at the same time provides the functional synthesis into which future molecular and computational studies can be woven. The neurobiology of an insect brain is an important milestone in our search for unifying principles of brain organisation and will be essential reading for students and research workers in neurobiology, behaviour, and entomology. our understanding

There are many modes of communication that neurons use to transmit information besides what has come to be called neurotransmission. Many of these other types of communication can be classified as neuromodulatory, where instead of conveying excitation or inhibition, the signal from one neuron changes the properties of other neurons or synapses. This form of neuronal communication is often overlooked by systems physiologists, but it is extremely prevalent in the nervous system and needs to be included in any description of how the nervous system processes information. This book provides the foundations for understanding the cellular and molecular basis for neuromodulatory effects. It illustrates some key examples of the roles played by neuromodulation in sensory processing, neuromuscular transmission, generation of motor behaviours, and learning. Finally, the book seeks to point out areas that are likely to be of importance in the future study of information processing by the nervous system. For neurobiology students and researchers, the book summarizes a vast amount of research, and puts it into the context of how these cellular mechanisms are used in systems of neurons. By spanning the levels of analysis from sub-cellular mechanisms through cellular properties and neuronal systems to behaviour, the book provides a framework for understanding this currently exploding field of research. It is accessible to anyone with a basic understanding of neurobiology, but is in depth enough to satisfy readers who are very familiar with the field.

A Best Book of 2020: The Washington Post * NPR * Chicago Tribune * Smithsonian A "remarkable" (Los Angeles Times), "seductive" (The Wall Street Journal) debut from the new cohost of Radiolab, Why Fish Don't Exist is a dark and astonishing tale of love, chaos, scientific obsession, and--possibly--even murder. "At one point, Miller dives into the ocean into a school of fish...comes up for air, and realizes she's in love. That's how I felt: Her book took me to strange depths I never imagined, and I was smitten." --The New York Times Book Review David Starr Jordan was a taxonomist, a man possessed with bringing order to the natural world. In time, he would be credited with discovering nearly a fifth of the fish known to humans in his day. But the more of the hidden blueprint of life he uncovered, the harder the universe seemed to try to thwart him. His specimen collections were demolished by lightning, by fire, and eventually by the 1906 San Francisco earthquake--which sent more than a thousand discoveries, housed in fragile glass jars, plummeting to the floor. In an instant, his life's work was shattered. Many might have given up, given in to despair. But Jordan? He surveyed the wreckage at his feet, found the first fish that he recognized, and confidently began to rebuild his collection. And this time, he introduced one clever innovation that he believed would at last protect his work against the chaos of the world. When NPR reporter Lulu Miller first heard this anecdote in passing, she took Jordan for a fool--a cautionary tale in hubris, or denial. But as her own life slowly unraveled, she began to wonder about him. Perhaps instead he was a model for how to go on when all seemed lost. What she would unearth about his life would transform her understanding of history, morality, and the world beneath her feet. Part biography, part memoir, part scientific adventure, Why Fish Don't Exist is a wondrous fable about how to persevere in a world where chaos will always prevail.

Eye movements are a vital part of our interaction with the world. They play a pivotal role in perception, cognition, and education. Research in this field is now proceeding at a considerable pace and casting new light on how the eyes move and what information we can derive during the frequent and brief periods of fixation. However, the origins of this work are less well known, even though much of our knowledge was derived from this research with far more primitive equipment. This book is unique in tracing the history of eye movement research. It shows how great strides were made in this area before modern recording devices were available, especially in the measurement of nystagmus. When photographic techniques were adapted to measure discontinuous eye movements, from about 1900, many of the issues that are now basic to modern research were then investigated. One of the earliest cognitive tasks examined was reading, and it remains in the vanguard of contemporary research. Modern researchers in this field will be astonished at the subtleties of these early experimental studies and the ingenuity of interpretations that were advanced one and even two centuries ago. Though physicians often carried out the original eye movement research, later on it was pursued by psychologists - it is within contemporary neuroscience that we find these two strands reunited. Anyone interested in the origins of psychology and neuroscience will find much to stimulate and surprise them in this valuable new work.

This book summarizes the most recent data on the molecular and cellular mechanisms which determine the unique properties of nerve cells - their ability to differentiate, establish connections to each other, and to form the nervous system with its immense capability for receiving, analysing, and storing information about our external and internal world. The key role of calcium ions in this process is particularly explored, along with nervous system function in aging and neural pathology. The author, based at a high-profile research unit in the Ukraine, is able to draw on significant new research which has not been widely published. Plasticity in nerve cell function will be of interest to researchers and research students in the fields of neurophysiology, cellular physiology, biophysics, and neurochemistry in particular. It will also be of relevance to researchers and medical doctors interested in neuropathology and aging.

Sentient assembles a menagerie of zoological creatures – from land, air, sea and all four corners of the globe – to understand what it means to be human. Through their eyes, ears, skins, tongues and noses, the furred, finned and feathered reveal how we sense and make sense of the world, as well as the untold scientific revolution stirring in the field of human perception.

The harlequin mantis shrimp can throw a punch that can fracture aquarium walls but, more importantly, it has the ability to see a vast range of colours. The ears of the great grey owl have such unparalleled range and sensitivity that they can hear twenty decibels lower than the human ear. The star-nosed mole barely fills a human hand, seldom ventures above ground and poses little threat unless you are an earthworm, but its miraculous nose allows it to catch those worms at astonishing speed – as little as one hundred and twenty milliseconds. Here, too, we meet the four-eyed spookfish and its dark vision; the vampire bat and its remarkable powers of touch; the bloodhound and its hundreds of millions of scent receptors, as well as the bar-tailed godwit, the common octopus, giant peacocks, cheetahs and golden orb-weaving spiders. Each of these extraordinary creatures illustrates the sensory powers that lie dormant within us.

In this captivating book, Jackie Higgins explores this evolutionary heritage and, in doing so, enables us to subconsciously engage with the world in ways we never knew possible.

'Gow reinvents what it means to be a guardian of the countryside.'-Guardian 'This authentic, impassioned manifesto-cum-memoir will hopefully have a major impact on what is likely to be a long-running controversy.'-The Spectator 'Gow has a fire in his belly. We need more like him.'-BBC Wildlife Magazine A Waterstones Best Nature Writing Book of 2020 'Bringing Back the Beaver is a hilarious, eccentric and magnificent account of a struggle . . . to reintroduce a species crucial to the health of our ecosystems.'-George Monbiot Bringing Back the Beaver is farmer-turned-ecologist Derek Gow's inspirational and often riotously funny first-hand account of how the movement to rewild beavers into the British landscape became the single most dramatic and subversive nature conservation act of the modern era. Since the early 1990s - in the face of outright opposition from government, landowning elites and even some conservation professionals - Gow has imported, quarantined and assisted the reestablishment of beavers in waterways across England and Scotland. With a foreword by bestselling author of Wilding, Isabella Tree, Bringing Back the Beaver makes a passionate case as to why the return of one of nature's great problem solvers will be critical as part of a sustainable fix for the UK's growing flooding problems, whilst ensuring the creation of essential landscapes that enable the broadest spectrum of Britain's wildlife to thrive. 'It is wonderful to see that beavers are now officially back on the list of native species, having been absent for so long . . . far too long!'-Dame Judi Dench

In recent years it has become increasingly clear that chemical interactions play a fundamental role in aquatic habitats and have far-reaching evolutionary and ecological consequences. A plethora of studies have shown that aquatic organisms from most taxa and functional groups respond to minute concentrations of chemical substances released by other organisms. However, our knowledge of this "chemical network" is still negligible. Chemical interactions can be divided into two larger sub-areas based on the function of the chemical substance. First, there are interactions where chemical substances are toxic to other organisms and are used as a defence against consumers (including both herbivores and predators) or a weapon against competitors (allelopathy). Second, chemical substances may be used as a source for information of the environment; for example: how can I find the optimal habitat, the best food, the nicest partner, and avoid being eaten? Aquatic organisms are able to detect and respond to extremely low concentrations of chemical cues to answer all these questions. The book aims at connecting these intriguing chemical interactions with traditional knowledge of organism interactions. Chemical Ecology of Aquatic Systems covers a wide range of studies, both plant and animal, from different geographic regions and habitats - pelagic as well as benthic. Most of the chemical interactions are similar in freshwater and marine habitats and this book therefore strives at integrating work on both systems.
