"Image segmentation is a process used in computer vision to partition an image into regions with similar characteristics. One category of image segmentation algorithms is graph-based, where pixels in an image are represented by vertices in a graph and the similarity between pixels is represented by weighted edges. A segmentation of the image can be found by cutting edges between dissimilar groups of pixels in the graph, leaving different clusters or partitions of the data. A popular graph-based method for segmenting images is the Normalized Cuts (NCuts) algorithm, which quantifies the cost for graph partitioning in a way that biases clusters or segments that are balanced towards having lower values than unbalanced partitionings. This bias is so strong, however, that the NCuts algorithm avoids any singleton partitions, even when vertices are weakly connected to the rest of the graph. For this reason, we propose the Compassionately Conservative Normalized Cut (CCNCut) objective function, which strikes a better compromise between the desire to avoid too many singleton partitions and the notion that all partitions should be balanced. We demonstrate how CCNCut minimization can be relaxed into the problem of computing Piecewise Flat Embeddings (PFE) and provide an overview of, as well as two efficiency improvements to, the Splitting Orthogonality Constraint (SOC) algorithm previously used to approximate PFE. We then present a new algorithm for computing PFE based on iteratively minimizing a sequence of reweighted Rayleigh quotients (IRRQ) and run a series of experiments to compare CCNCut-based image segmentation via SOC and IRRQ to NCut-based image segmentation on the BSDS500 dataset. Our results indicate that CCNCut-based image segmentation yields more accurate results with respect to ground truth than NCut-based segmentation, and IRRQ is less sensitive to initialization than SOC."--Abstract.

Estimates indicate that as many as 1 in 4 Americans will experience a mental health problem or will misuse alcohol or drugs in their lifetimes. These disorders are among the most highly stigmatized health conditions in the United States, and they remain barriers to full participation in society in areas as basic as education, housing, and employment. Improving the lives of people with mental health and substance abuse disorders has been a priority in the United States for more than 50 years. The Community Mental Health Act of 1963 is considered a major turning point in America's efforts to improve behavioral healthcare. It ushered in an era of optimism and hope and laid the groundwork for the consumer movement and new models of recovery. The consumer movement gave voice to people with mental and substance use disorders and brought their perspectives and experience into national discussions about mental health. However over the same 50-year period, positive change in American public attitudes and beliefs about mental and substance use disorders has lagged behind these advances. Stigma is a complex social phenomenon based on a relationship between an attribute and a stereotype that assigns undesirable labels, qualities, and behaviors to a person with that attribute. Labeled individuals are then socially devalued, which leads to inequality and discrimination. This report contributes to national efforts to understand and change attitudes, beliefs and behaviors that can lead to stigma and discrimination. Changing stigma in a lasting way will require coordinated efforts, which are based on the best possible evidence, supported at the national level with multiyear funding, and planned and implemented by an effective coalition of representative stakeholders. Ending Discrimination Against People with Mental and Substance Use Disorders: The Evidence for Stigma Change explores stigma and discrimination faced by individuals with mental or substance use disorders and recommends effective strategies for reducing stigma and encouraging people to seek treatment and other supportive services. It offers a set of conclusions and recommendations about successful stigma change strategies and the research needed to inform and evaluate these efforts in the United States.

Here is a searing account-probably the best yet published-of life in the underclass and why it persists as it does. Theodore Dalrymple, a British psychiatrist who treats the poor in a slum hospital and a prison in England, has seemingly seen it all. Yet in listening to and observing his patients, he is continually astonished by the latest twist of depravity that exceeds even his own considerable experience. Dalrymple's key insight in Life at the Bottom is that long-term poverty is caused not by economics but by a dysfunctional set of values, one that is continually reinforced by an elite culture searching for victims. This culture persuades those at the bottom that they have no responsibility for their actions and are not the molders of their own lives. Drawn from the pages of the cutting-edge political and cultural quarterly City Journal, Dalrymple's book draws upon scores of eye-opening, true-life vignettes that are by turns hilariously funny, chillingly horrifying, and all too revealing-sometimes all at once. And Dalrymple writes in prose that transcends journalism and achieves the quality of literature.

For patients and their loved ones, no care decisions are more profound than those made near the end of life. Unfortunately, the experience of dying in the United States is often characterized by fragmented care, inadequate treatment of distressing symptoms, frequent transitions among care settings, and enormous care responsibilities for families. According to this report, the current health care system of rendering more intensive services than are necessary and desired by patients, and the lack of coordination among programs increases risks to patients and creates avoidable burdens on them and their families. Dying in America is a study of the current state of health care for persons of all ages who are nearing the end of life. Death is not a strictly medical event. Ideally, health care for those nearing the end of life harmonizes with social, psychological, and spiritual support. All people with advanced illnesses who may be approaching the end of life are entitled to access to high-quality, compassionate, evidence-based care, consistent with their wishes. Dying in America evaluates strategies to integrate care into a person- and family-centered, team-based framework, and makes recommendations to create a system that coordinates care and supports and respects the choices of patients and their families. The findings and recommendations of this report will address the needs of patients and their families and assist policy makers, clinicians and their educational and credentialing bodies, leaders of health care delivery and financing organizations, researchers, public and private funders, religious and community leaders, advocates of better care, journalists, and the public to provide the best care possible for people nearing the end of life.

Crime, Shame and Reintegration is a contribution to general criminological theory. Its approach is as relevant to professional burglary as to episodic delinquency or white collar crime. Braithwaite argues that some societies have higher crime rates than others because of their different processes of shaming wrongdoing. Shaming can be counterproductive, making crime problems worse. But when shaming is done within a cultural context of respect for the offender, it can be an extraordinarily powerful, efficient and just form of social control. Braithwaite identifies the social conditions for such successful shaming. If his theory is right, radically different criminal justice policies are needed - a shift away from punitive social control toward greater emphasis on moralizing social control. This book will be of interest not only to criminologists and sociologists, but to those in law, public administration and politics who are concerned with social policy and social issues.

How do we understand mental health problems in their social context? A former BMA Medical Book of the Year award winner, this book provides a sociological analysis of major areas of mental health and illness. The book considers contemporary and historical aspects of sociology, social psychiatry, policy and therapeutic law to help students develop an in-depth and critical approach to this complex subject.New developments for the fifth edition include: Brand new chapter on prisons, criminal justice and mental health Expanded coverage of stigma, class and social networks Updated material on the Mental Capacity Act, Mental Health Act and the Deprivation of Liberty A classic in its field, this well established textbook offers a rich and well-crafted overview of mental health and illness unrivalled by competitors and is essential reading for students and professionals studying a range of medical sociology and health-related courses. It is also highly suitable for trainee mental health workers in the fields of social work, nursing, clinical psychology and psychiatry. "Rogers and Pilgrim go from strength to strength! This fifth edition of their classic text is not only a sociology but also a psychology, a philosophy, a history and a polity. It combines rigorous scholarship with radical argument to produce incisive perspectives on the major contemporary questions concerning mental health and illness. The authors admirably balance judicious presentation of the range of available understandings with clear articulation of their own positions on key issues. This book is essential reading for everyone involved in mental health work." Christopher Dowrick, Professor of Primary Medical Care, University of Liverpool, UK "Pilgrim and Rogers have for the last twenty years given us the key text in the sociology of mental health and illness. Each edition has captured the multi-layered and ever changing landscape of theory and practice around psychiatry and mental health, providing an essential tool for teachers and researchers, and much loved by students for the dexterity in combining scope and accessibility. This latest volume, with its focus on community mental health, user movements criminal justice and the need for inter-agency working, alongside the more classical sociological critiques around social theories and social inequalities, demonstrates more than ever that sociological perspectives are crucial in the understanding and explanation of mental and emotional healthcare and practice, hence its audience extends across the related disciplines to everyone who is involved in this highly controversial and socially relevant arena." Gillian Bendelow, School of Law Politics and Sociology, University of Sussex, UK "From the classic bedrock studies to contemporary sociological perspectives on the current controversy over which scientific organizations will define diagnosis, Rogers and Pilgrim provide a comprehensive, readable and elegant overview of how social factors shape the onset and response to mental health and mental illness. Their sociological vision embraces historical, professional and socio-cultural context and processes as they shape the lives of those in the community and those who provide care; the organizations mandated to deliver services and those that have ended up becoming unsuitable substitutes; and the successful and unsuccessful efforts to improve the lives through science, challenge and law."

Drug overdose, driven largely by overdose related to the use of opioids, is now the leading cause of unintentional injury death in the United States. The ongoing opioid crisis lies at the intersection of two public health challenges: reducing the burden of suffering from pain and containing the rising toll of the harms that can arise from the use of opioid medications. Chronic pain and opioid use disorder both represent complex human conditions affecting millions of Americans and causing untold disability and loss of function. In the context of the growing opioid problem, the U.S. Food and Drug Administration (FDA) launched an Opioids Action Plan in early 2016. As part of this plan, the FDA asked the National Academies of Sciences, Engineering, and Medicine to convene a committee to update the state of the science on pain research, care, and education and to identify actions the FDA and others can take to respond to the opioid epidemic, with a particular focus on informing FDA's development of a formal method for incorporating individual and societal considerations into its risk-benefit framework for opioid approval and monitoring.

Named one of Vulture’s Top 10 Best Books of 2020! Leftist firebrand Fredrik deBoer exposes the lie at the heart of our educational system and demands top-to-bottom reform. Everyone agrees that education is the key to creating a more just and equal world, and that our schools are broken and failing. Proposed reforms variously target incompetent teachers, corrupt union practices, or outdated curricula, but no one acknowledges a scientifically-proven fact that we all understand intuitively: Academic potential varies between individuals, and cannot be dramatically improved. In The Cult of Smart, educator and outspoken leftist Fredrik deBoer exposes this omission as the central flaw of our entire society, which has created and perpetuated an unjust class structure based on intellectual ability. Since cognitive talent varies from person to person, our education system can never create equal opportunity for all. Instead, it teaches our children that hierarchy and competition are natural, and that human value should be based on intelligence. These ideas are counter to everything that the left believes, but until they acknowledge the existence of individual cognitive differences, progressives remain complicit in keeping the status quo in place. This passionate, voice-driven manifesto demands that we embrace a new goal for education: equality of outcomes. We must create a world that has a place for everyone, not just the academically talented. But we’ll never achieve this dream until the Cult of Smart is destroyed.
