Medical Misinformation and Social Harm in Non-Science Based Health Practices A Multidisciplinary Perspective

Fraudulent harmful or at best useless pharmaceutical and therapeutic approachesdeveloped outside science-based medicine have boomed in recent years especially due tothe commercialisation of cyberspace. The latter has played a fundamental role in the riseof false ‘health experts’ and in the creation of filter bubbles and echo chambers that havecontributed to the formation of highly polarised debates on non-science-based healthpractices—online as well as offline. By adopting a multidisciplinary approach this edited book brings togethercontributions of international academics and practitioners from criminology digitalsociology health psychology medicine law physics and journalism where they criticallyanalyse different types of non-science-based health approaches. With this volume we aimto reconcile different scientific understandings of these practices synthesising a varietyof empirical theoretical and interpretative approaches and exploring the challenges implications and potential remedies to the spread of dangerous and misleading healthinformation. This edited book will offer some food for thought not only to students and academicsin the social sciences health psychology and medicine among other disciplines but alsoto medical practitioners science journalists debunkers policy makers and the generalpublic as they might all benefit from a greater awareness and critical knowledge of theharms caused by non-scientific health practices. | Medical Misinformation and Social Harm in Non-Science Based Health Practices A Multidisciplinary Perspective

The Internet of Materials

State-of-the-art flat structures called metasurfaces can filter and steer light and sound render an object completely invisible to electromagnetic waves and much more. They can deliver automation remote operation and advanced performance to a wide variety of existing systems with applications in communications medical imaging sensing and security. However for non-specialists individual metasurfaces are currently restricted to limited reusability and accessibility. This book brings together various scientific disciplines with the aim of outlining a programmable ‘plug-and-play’ metasurface. The book focuses on a recently proposed platform – known as the HyperSurface – that provides many electromagnetic functions of metasurfaces in a single structure which can be controlled and reconfigured by software. This revolutionary approach paves the way for new opportunities in wireless communications and programmable wireless environments: HyperSurfaces could link networks with objects and physical environments and create smarter systems that are far more responsive to user demands. Walls that absorb radiation or block digital eavesdropping and wireless long-distance charging of devices are among the many possibilities. The book aspires to provide the foundational knowledge for creating an Internet of Materials enabling smart environments at any scale – from indoor wireless communications to medical imaging equipment. Although the set of disciplines involved covers a considerable span we hope that the material will benefit experts and students alike. | The Internet of Materials

Psychoanalytic Defense Mechanisms in Cognitive Multi-Agent Systems

Human cognitive processes and defense mechanisms as described in psychoanalysis bring about new notions and paradigms for artificial intelligence systems. One key reason is that the human cognitive processes and defense mechanisms in question can accomplish conflict detection functionalities filter functionalities and other system stabilizing tasks within artificial intelligence systems. Yet artificial cognitive architectures lack the capability to analyze complex situations as well as the universal competencies needed to orientate themselves in complex environments in various domains. Psychoanalytic Defense Mechanisms in Cognitive Multi-Agent Systems addresses this dilemma by exploring how to describe model and implement psychoanalytic defense mechanisms in the course of a project that provides a functional model of the human mind. With discussions focusing on the development of a mathematical description for the implementation of conflict detection the activation and selection of defense mechanisms and the processing of defense mechanisms Psychoanalytic Defense Mechanisms in Cognitive Multi-Agent Systems describes the decisive points for the application of defense mechanisms in artificial intelligence. Formulae that treat defense mechanisms as transformations are also provided. Interdisciplinary cooperation between the scientific fields of psychoanalysis and artificial intelligence is highlighted as the foundation of new research findings throughout the book. Innovative and exciting this book will be of great interest to academics researchers and postgraduates in the fields of cognitive science artificial intelligence and psychoanalysis.

Sex at Risk Lifetime Number of Partners Frequency of Intercourse and the Low AIDS Risk of Vaginal Intercourse

Politicians interest groups and the mass media often answer questions about how AIDS is sexually transmitted as if heterosexual vaginal intercourse is a high-risk activity. When it comes to understanding how AIDS is transmitted and formulating effective policy to deal with the spread of AIDS America remains confused. What. Brody calls ideological knowledge about AIDS is fat more likely to filter through society than scientific knowledge. Sex at Risk Is a comprehensive review of the scientific literature dealing with. the transmission of AIDS. Like Michael Fumento's The Myth of Heterosexual AIDS it exposes the mythology surrounding vaginal intercourse and AIDS transmission Brody also looks deeply at reasons that fear of AIDS transmission from vaginal intercourse has spread so widely and profoundly He addresses serious methodological problems in AIDS/HIV behavioral research as well as tendentious political correctness that has done a disservice to science. Sex at Risk also comprehensively reviews the international research literature on correlates of lifetime number of sexual partners and frequency of sexual intercourse. Among topics covered are: relationships between lifetime number of sexual partners and mental health explanations for important differences between intercourse and masturbation the possible association of frequency with healthy functioning and correlations between frequency and national development. Brody concludes by discussing what AIDS reveals about how politically correct thought impedes scientific progress when taboo themes regardless of their validity cannot be pursued Sex at Risk is factually grounded yet controversial; . Brody raises critical questions about much of what we have learned about AIDS from popular and professional publications soft scientists and public health campaigns. It will be of interest to medical doctors clinicians and those interested in the sociology and psychology of knowledge | Sex at Risk Lifetime Number of Partners Frequency of Intercourse and the Low AIDS Risk of Vaginal Intercourse

Electronics for Scientists

Electronics for Scientists provides a practical and concise introduction to electrical circuits signals and instrumentation for undergraduate students in the physical sciences. No previous familiarity with electronics is required and concepts are grounded in the relevant physics. The book aims to give students the electronics background needed to be successful in experimental science. The book begins with the fundamentals of DC circuits. This is followed by AC circuits and their analysis using the concept of impedance. The transfer function is introduced and used to analyze different types of filter circuits. The conversion between time-domain and frequency-domain signal representations is reviewed. Transmission lines are introduced and used to motivate the different approach to designing microwave-frequency circuits as compared to lower-frequency circuits. The physics of semiconductors is reviewed and used to understand the behavior of diodes and transistors and a number of diode and transistor circuits are analyzed. The operational amplifier (op-amp) is introduced and several op-amp circuits are analyzed. Techniques for quantifying noise in electrical measurements are described and common sources of noise are discussed. The last major topic is digital circuits which include analog-to-digital conversion logic gates and digital memory circuits. The book concludes with a brief introduction to quantum computing. Designed for a one-semester course this book brings together a range of topics relevant to experimental science that are not commonly found in a single text. Worked examples are provided throughout the book and each chapter concludes with a set of problems to reinforce the material covered. The subject of electronics is indispensable to a wide array of scientific and technical fields and this book seeks to provide an approachable point of access to this rich and important subject.
