Lasers are now recognized as practical alternatives to conventional techniques for many industrial applications. After reviewing the basic theory the book provides an insight into equipment technology and applications.
Management theory is vague about the experience of leading. Success, power, achievement are discussed but less focus is given to negative experiences leaders faced such as loneliness or disappointment. This book addresses difficult-to-explore aspects of leadership through well-known works of literature drawing lessons from fictional leaders.
Secession is the creation of a new independent state out of an existing state. This key volume examines the political, social and legal processes of the practice of secession. Following an analysis of secessionist movements and their role in attempts at secession, eight case studies are explored to illustrate peaceful, violent, sequential and recursive secessions. This is followed by a look at the theoretical approaches and a discussion that focuses on the economic causes. Normative theories of secession are discussed as well as the status of secession in legal theory and practice. The book systematizes our present knowledge of secessions in an accessible way to readers not familiar with the phenomenon and its consequences. It is ideal as a supplementary text to courses on contemporary political and social movements, applied ethics and political philosophy, international relations and international law, state sovereignty and state formation.
Over the last two decades, molecular genetics and brain imaging have guided efforts to find the causes of schizophrenia. It is becoming increasingly clear that many genes are involved in schizophrenia and that they interact with other factors in very complex ways, which have not yet been elucidated. Neuroimaging techniques have allowed scientists and physicians to examine brain structure, function, and chemistry in living patients with schizophrenia but results so far have been disappointing. No two patients seem to share exactly the same combination of clinical symptoms or physical findings. Yet all have the syndrome recognized as schizophrenia. The author of this accessible, well-written book argues that it is time to set aside the search for a single cause of schizophrenia and focus on the disease's final common pathway. He highlights clues from a wide range of research, including neurotransmitter, psychophysiological, and brain imaging studies. He then describes possibilities for the final common pathway at an understandable level in the context of what is already known about schizophrenia. While there are no preferred models of schizophrenia, a pattern is emerging which implicates those structures in the brain known to be important in integrating perception, cognition, and affect. A better understanding of these processes will be critical for developing more effective treatments. This book will help advance that effort. It will be of great value to psychiatrists, psychologists, neurologists, neuroimagers, and basic scientists working in the field of schizophrenia research, and to their students and trainees. It will also be of interest to clinicians and scientists concerned with other neuropsychiatric disorders, and to the families of those diagnosed with schizophrenia.
The genetic correlates of neuropsychiatric disorders are now known, but none have come close to explaining the great variety of human psychiatric illnesses. This volume, written by a neuropsychiatrist and an evolutionary biologist, offers a new paradigm for understanding these disorders. Proposing that neuronal pathways which underlie neuropsychiatric conditions mirror unique human capabilities, the authors iterate a new paradigm by which to understand human psychiatric illnesses. Human capabilities such as theory of mind, language, and complex social behaviors are explored through their histological, neuroanatomical and functional brain imaging correlates. The capacity for representation, the authors suggest, is central to the understanding of the human brain. Brain structures such as the frontal pole, temporal pole, and fronto-insular cortex are highly developed in humans and are associated with representation. Other brain regions, including the dorsal anterior cingulate cortex, auditory cortex, and hippocampus, are linked with directed effort while the ventral anterior cingulate cortex, orbital frontal cortex, and amygdala are related to emotional encoding. Both networks interact with representional regions and the dorsolateral prefrontal cortex. Conditions like schizophrenia may result, in part, from a failure of the networks associated with directed effort while bipolar disorders may arise from a failure of networks associated with emotional encoding. Similarly, autism may result from a failure of representational brain regions; frontotemporal dementia may be associated with failure of several discrete networks in later life. From this perspective, neuropsychiatric disorders are selective failures of brain networks involved in the integration of cognition, affect and perception. A better understanding of these brain networks will assist psychiatric and mental health researchers in the search for environmental factors and genetic correlates of disorders as well as aid in the development of more effective treatments for these diseases. This volume will be of interest to psychiatrists, neurologists, psychologists, biologists, and imaging scientists--anyone who has ever wondered what makes the human brain human.
