Hermann Minkowski recast special relativity as essentially a new geometric structure for spacetime. This book looks at the ideas of both Einstein and Minkowski, and then introduces the theory of frames, surfaces and intrinsic geometry, developing the main implications of Einstein's general relativity theory.
With a fresh geometric approach that incorporates more than 250 illustrations, this textbook sets itself apart from all others in advanced calculus. Besides the classical capstones--the change of variables formula, implicit and inverse function theorems, the integral theorems of Gauss and Stokes--the text treats other important topics in differential analysis, such as Morse's lemma and the Poincaré lemma. The ideas behind most topics can be understood with just two or three variables. The book incorporates modern computational tools to give visualization real power. Using 2D and 3D graphics, the book offers new insights into fundamental elements of the calculus of differentiable maps. The geometric theme continues with an analysis of the physical meaning of the divergence and the curl at a level of detail not found in other advanced calculus books. This is a textbook for undergraduates and graduate students in mathematics, the physical sciences, and economics. Prerequisites are an introduction to linear algebra and multivariable calculus. There is enough material for a year-long course on advanced calculus and for a variety of semester courses--including topics in geometry. The measured pace of the book, with its extensive examples and illustrations, make it especially suitable for independent study.
Using both historical and contemporary contexts, The Child Welfare Challenge examines major policy practice and research issues as they jointly shape child welfare practice and its future. This text focuses on families and children whose primary recourse to services has been through publicly funded child welfare agencies, and considers historical areas of service—foster care and adoptions, in-home family-centered services, child-protective services, and residential treatment services—where social work has an important role. This fourth edition features new content on child maltreatment and prevention that is informed by key conceptual frameworks informed by brain science, public health, and other research. This edition uses cross-sector data and more sophisticated predictive and other analytical processes to enhance planning and practice design. The authors have streamlined content on child protective services (CPS) to allow for new chapters on juvenile justice/cross-over youth, and international innovations, as well as more content on biology and brain science. The fourth edition includes a glossary of terms as well as instructor and student resource papers available online.

Frail older people now contribute the majority of the acute emergency take both medical and surgical. Despite this there is often a lack of confidence and knowledge among doctors and nurses in treating older people in the Emergency Department and on Emergency Assessment Units.From the Preface Emergency care of frail older people is challenging but very rewarding. Older patients tend to be complex and therefore their assessment needs to be more extensive and include comprehensive geriatric assessment. It is the extras in their assessment that are not usually needed in younger patients, such as cognitive, functional and social evaluations that make the difference in achieving a better outcome. This book describes the key features of high quality care for frail elderly patients in acute hospital settings. With chapters on assessment and the characteristic non-specific ways that patients tend to present (such as 'confusion', 'collapse query cause' and 'off legs'), this practical guide is ideal to have on-hand. As well as common medical and surgical conditions, it also covers medication management, elder abuse, pressure ulcers and hypothermia, including the physiological changes seen in ageing and ways to define frail patients. Tables, diagrams and images are ideal for quick reference, and key points are summarised throughout the text to aid comprehension, providing doctors, nurses and therapists with both background and essential information to provide the excellent acute care older people deserve.

Because limited training in geriatric psychiatry has tended to give insufficient attention to mental health care for the elderly, clinicians often need help when assessing and treating problems specific to older clients. Clinical Manual of Geriatric Psychiatry provides a single-volume reference that covers the full range of such problems, from depression to dementia. It shows that psychiatrists working with older people must sometimes be willing to play a generalist's role, combining routine medical management with psychiatric interventions or helping with social or situational problems. Drs. Spar and La Rue review the effects of aging on cognitive performance, including clinical presentations of memory loss and medication-induced symptoms of mental disorder. They offer practical guidance to help the clinician not only diagnose and treat these conditions but also address such issues as evaluating competency for informed consent. Enhanced by numerous charts and tables for easy reference, the book boasts a broad range of coverage: • Guidelines to differential diagnosis of depression -- laboratory tests, psychological tests, and symptom rating scales -- along with insights on new directions in psychotherapy, including intervention within primary care. • Assessment of both selective serotonin reuptake inhibitors and non-SSRIs as first-line agents for depression, citing advantages and disadvantages of specific drugs, plus advice on switching or combining antidepressants.• Discussion of the effective use of electroconvulsive therapy -- particularly the use of brief-pulse, bilateral electrode placement -- as well as experimental therapies such as repetitive transcranial magnetic stimulation and vagal nerve stimulation. • Guidance in cognitive mental status examinations and brief screening tools for dementia and Alzheimer's disease, focusing on the Mini-Mental State Exam and summarizing advanced and experimental diagnostics such as single photon emission computed tomography and positron emission tomography. • Appraisal of psychosocial therapies for patients with Alzheimer's Disease, such as behavior modification and reminiscence therapy, plus use of cholinesterase inhibitors for treatment of cognitive deficits.• Review of approaches to anxiety disorders, including differential diagnosis of phobias, generalized anxiety disorder, obsessive-compulsive disorder, and panic disorder, with a focus on psychosocial-behavior therapy and medications of choice. With life expectancies increasing, people over 85 already constitute one of the fastest growing demographics -- and the number of older people with mental disorders is rising as well. Clinical Manual of Geriatric Psychiatry explains how working effectively with older adults requires a blending of specialized knowledge with a flexible approach to the patient -- and shows how to bring that about in daily practice.
