This book addresses different challenges that endanger the lives of children in South Africa from an ethical perspective. The text is meant to position itself as a resource for specialists (and practitioners) in ethics and childhood studies. The content is systematically and intersectionally presented, based on scholarly analyses, insights, reasoning, and expertise – originating in different disciplines and backgrounds. It endeavours to help especially those who study the sociocultural contexts of children and families in terms of challenges and opportunities, and for possible support.
The replacement of a degenerated joint such as the hip and knee is one of the most outstanding interventions that allows the medical community to restore the patient's quality of life. However, today's patient is increasingly younger and more active and this presents a challenge for the orthopaedic community as a greater demand has been created for a longer lasting artificial joint that can allow the patient to maintain their lifestyle and thus new approaches in biotribology have been focused on this area of research. This invaluable book provides a broad introduction to the boundary conditions, developments and latest research activities already available to the surgeon and offers an insight into solutions being developed for new high performance bearings in joint replacements. The contributors are leading experts in their field and this is the first complete volume to bring together such unique insights. Orthopaedic engineers, surgeons and researchers concerned with new biomaterials would find this a vital reference volume to evaluate the latest state of research in the area."--
Bringing together conventional contrast media studies, computed tomography, ultrasound, magnetic resonance imaging, radionuclide imaging including hybrid imaging using SPECT-CT and PET-CT, DXA studies and digital interventional procedures into one volume, this definitive book is the essential source of information on the use and application of these imaging modalities in radiography. Taking a systemic anatomical approach, carefully designed to be clear and consistent throughout and mirroring that in the popular and established textbook Clark’s Positioning in Radiography, each chapter is highly illustrated and contains sections detailing anatomy, pathologic considerations, procedure methodology, and an evaluation of recommended imaging modalities. Reflecting the latest clinical imaging pathways and referral guidelines including IR(ME)R 2017, the Map of Medicine and RCR iRefer (8E), Clark’s Diagnostic Imaging Procedures will quickly become established as the standard textbook for students of radiography and radiographer assistant trainees and an invaluable desk reference for practising radiologists.
This easy-to-understand pocketbook in the highly respected Clark’s stable of diagnostic imaging texts is an invaluable tool for students, sonographers and other ultrasound practitioners, providing practical guidance on clinical ultrasound procedures, summarising current relevant literature and professional body guidelines. The content is arranged by anatomical system and organ for ease of reference, with each section comprising a short introduction, the indications for the procedure, patient preparation, the imaging procedure itself, along with an image analysis, supported throughout by positioning photographs and clinical images. Clark’s Essential Guide to Clinical Ultrasound is ideal for all users of clinical ultrasound at both undergraduate and postgraduate level and will also provide a convenient distillation of the latest best practice and guidelines for sonographers, midwives, vascular technologists, ECG technologists, medical doctors, sports injury specialists, paramedics, and other health professionals.
Like stars, societies are born, and this story deals with such a birth. It asks a fundamental and compelling question: How did societies first coalesce from the small foraging communities that had roamed in West Central Africa for many thousands of years? Jan Vansina continues a career-long effort to reconstruct the history of African societies before European contact in How Societies Are Born. In this complement to his previous study Paths in the Rainforests, Vansina employs a provocative combination of archaeology and historical linguistics to turn his scholarly focus to governance, studying the creation of relatively large societies extending beyond the foraging groups that characterized west central Africa from the beginning of human habitation to around 500 BCE, and the institutions that bridged their constituent local communities and made large-scale cooperation possible. The increasing reliance on cereal crops, iron tools, large herds of cattle, and overarching institutions such as corporate matrilineages and dispersed matriclans lead up to the developments treated in the second part of the book. From about 900 BCE until European contact, different societies chose different developmental paths. Interestingly, these proceeded well beyond environmental constraints and were characterized by "major differences in the subjects which enthralled people," whether these were cattle, initiations and social position, or "the splendors of sacralized leaders and the possibilities of participating in them.
