This book presents a logical system of critical appraisal, to allow readers to evaluate studies and to carry out their own studies more effectively. This system emphasizes the central importance of cause and effect relationships. Its great strength is that it is applicable to a wide range of issues, and both to intervention trials and observational studies. This system unifies the often different approaches used in epidemiology, health services research, clinical trials, and evidence-based medicine, starting from a logical consideration of cause and effect. The author's approach to the issues of study design, selection of subjects, bias, confounding, and the place of statistical methods has been praised for its clarity and interest. Systematic reviews, meta-analysis, and the applications of this logic to evidence-based medicine, knowledge-based health care, and health practice and policy are discussed. Current and often controversial examples are used, including screening for prostate cancer, publication bias in psychiatry, public health issues in developing countries, and conflicts between observational studies and randomized trials. Statistical issues are explained clearly without complex mathematics, and the most useful methods are summarized in the appendix. The final chapters give six applications of the critical appraisal of major studies: randomized trials of medical treatment and prevention, a prospective and a retrospective cohort study, a small matched case-control study, and a large case-control study. In these chapters, sections of the original papers are reproduced and the original studies placed in context by a summary of current developments.

Stem cell therapy is ushering in a new era of medicine in which we will be able to repair human organs and tissue at their most fundamental level- that of the cell. The power of stem cells to regenerate cells of specific types, such as heart, liver, and muscle, is unique and extraordinary. In 1998 researchers learned how to isolate and culture embryonic stem cells, which are only obtainable through the destruction of human embryos. An ethical debate has raged since then about the ethics of this research, usually pitting pro-life advocates vs. those who see the great promise of curing some of humanity's most persistent diseases.
In this book Cynthia Cohen agrees that we need to work toward a consensus on the issue of how we treat the embryo. But more broadly she claims that we need to transform and expand the ethical and policy debates on stem cells (adult and embryonic). This important and much-needed book is both a primer and a means by which to understand the implications of this research. Cohen starts by introducing readers to the basic science of stem cell research, and the core ethical questions surrounding the embryo. She then expands the scope of the debate, looking at the moral questions that will crop up down the line, such as e.g. the use of therapeutic cloning to overcome the body's immune resistance to stem cells; the ethics of using animals to test stem cells; how to disentangle federal and state legal and regulatory policies in pursuit of a coherent national policy; and how to develop an ethics of stem cell research that will accommodate new techniques and controversies that we cannot even foresee now. Her final chapter develops a concrete plan for an oversight systemfor this research.
This is the first single-author book that addresses the many broad ethical and legal issues related to stem cells, and it should be of great interest to bioethicists, researchers, clinicians, philosophers, theologians, lawyers, policy makers, and general readers.

This book combines a vast collection of data on phonological acquisition with close attention to Optimality Theory. It blends the studies of linguistics, psycholinguistics, and speech-language pathology in reference to phonological development. It also contains a step-by-step evaluation of competing theories while presenting a complete view of non-linear phonology, including adult grammar, psychological processing, first and second language acquisition, and inter-generational language changes. The authors focus on speech production rather than perception, emphasizing data from the period of real words. The many tables and phonological trees help to make this timely and useful study accessible to students and professionals alike. Among its key features it: addresses the full range of phonological patterns observed in children's speech; surveys patterns of development in children's speech; and provides the only existing single framework for children's phonological development.

Bioinspired Design of Materials Surfaces reviews novel methods and technologies used to design surfaces and materials for smart material and device applications. The author discusses how materials wettability can be impacted by the fabrication of micro- and nanostructures, anisotropic structures, gradient structures, and heterogeneous patterned structures on the surfaces of materials. The design of these structures was inspired by nature, including lotus, cactus, beetle back and butterfly wings, spider silk, and shells. The author reviews the various wettability functions that can result from these designs, such as self-cleaning, directional adhesion, droplet driving, anti-adhesion, non-wetting, liquid repellent properties, liquid separation, liquid splitting, and more. This book presents a key reference on how to fabricate bioinspired structures on materials for desired functions of materials wettability. It also discusses challenges, opportunities and many potential applications, such as oil-water separation devices, water harvesting devices and photonic device applications.

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.

It is well known that the class of steroid hormones known as estrogens have powerful effects on organs related to reproduction such as the uterus and the breast. What is less well known is that estrogens also profoundly modulate brain function and behavior. Estrogens, such as estradiol, can occur in brain as the result of ovarian secretion of the hormone into the blood that then finds its way to the brain. In male vertebrates, the testes secrete androgens, such as testosterone, into the blood and this class of steroid hormones can be converted into estrogens in the brain via the action of the enzyme aromatase which is expressed in the male brain in many species. Finally estradiol can be synthesized de novo from cholesterol as it has been shown in a variety of species that all the enzymes required to synthesize estrogens are expressed in the brain. This book collects chapters by experts in the field that considers, how estradiol is synthesized in the brain and what its effects are on a variety of behaviors. Special attention is paid to the enzyme aromatase that is distributed in discrete regions of the brain and is highly regulated in a sex specific and seasonal specific manner. Recently it has become clear that estrogens can act in the brain at two very different time scales, one is rather long lasting (days to weeks) and involves the modulation of gene transcription by the hormone-receptor complex. A second mode of action is much quicker and involves the action of estrogens on cell membranes that can result in effects on second messenger systems and ultimately behavior within minutes. Thus this book highlights novel views of estrogen action that are still under-appreciated namely that estrogens have significant effects on the male brain and that they can act on two very different times scales. This volume will be of interest to both basic researchers and clinicians interested in the action of estrogens.

The common, existing distance between children and adults is the basis of this work, which has been addressed in many literary and cultural works throughout history. Not being able to remember how we, now adults, thought as children -like their spontaneity or magic and omnipotent form of thinking- would leave children completely isolated, like a helpless immigrant in a foreign land. This book attempts to comprehend, how parents' misunderstanding, can induce loneliness and helplessness in children, that with time will become traumatic, and will remain unconsciously present in all of us forever. It will continue to repeat using infantile emotions, children form of thinking, and experiencing as well, loneliness, anxiety, depression, fears and the chronic need of finding a 'rescuer', in the form of power, fame, drugs, money, religion, and so on. This very innovative approach to the understanding of children's segregation and its repercussion on adult's emotional life, will be of invaluable interest to all practicing psychoanalysts, psychotherapists, and parents included.
