This wide-ranging volume presents an in-depth picture of adolescent sexuality and behavior. As perhaps the most vital period in human development, adolescence is a time of complex, often difficult interactions between diverse influences. Here, nineteen scientists representing ten disciplines explore the biological, psychological, and cultural factors involved in the onset of puberty and its associated emotional changes. Patterns of adolescent sexual behavior are viewed in cross-cultural perspective, psychiatric disorders are considered, and trends in adolescent sexual activity, contraception, and pregnancy are described. Key legal and social dilemmas are also explored. This is the third volume in a groundbreaking series from the Kinsey Institute, which has as its aim the study of topics relating to sex, gender, and reproduction that require an interdisciplinary approach. Previous volumes in the series include Homosexuality/Heterosexuality and Masculinity/Femininity.

Although there is extensive literature in the field of behavioral ecology that attempts to explain foraging of individuals, social foraging--the ways in which animals search and compete for food in groups--has been relatively neglected. This book redresses that situation by providing both a synthesis of the existing literature and a new theory of social foraging. Giraldeau and Caraco develop models informed by game theory that offer a new framework for analysis. "Social Foraging Theory" contains the most comprehensive theoretical approach to its subject, coupled with quantitative methods that will underpin future work in the field. The new models and approaches that are outlined here will encourage new research directions and applications.

To date, the analysis of social foraging has lacked unifying themes, clear recognition of the problems inherent in the study of social foraging, and consistent interaction between theory and experiments. This book identifies social foraging as an economic interaction between the actions of individuals and those of other foragers. This interdependence raises complex questions about the size of foraging groups, the diversity of resources used, and the propensity of group members to exploit each other or forage cooperatively. The models developed in the book will allow researchers to test their own approaches and predictions. Many years in development, Social Foraging Theory will interest researchers and graduate students in such areas as behavioral ecology, population ecology, evolutionary biology, and wildlife management.

This book provides a solution to the ecological inference problem, which has plagued users of statistical methods for over seventy-five years: How can researchers reliably infer individual-level behavior from aggregate (ecological) data? In political science, this question arises when individual-level surveys are unavailable (for instance, local or comparative electoral politics), unreliable (racial politics), insufficient (political geography), or infeasible (political history). This ecological inference problem also confronts researchers in numerous areas of major significance in public policy, and other academic disciplines, ranging from epidemiology and marketing to sociology and quantitative history. Although many have attempted to make such cross-level inferences, scholars agree that all existing methods yield very inaccurate conclusions about the world. In this volume, Gary King lays out a unique--and reliable--solution to this venerable problem.

King begins with a qualitative overview, readable even by those without a statistical background. He then unifies the apparently diverse findings in the methodological literature, so that only one aggregation problem remains to be solved. He then presents his solution, as well as empirical evaluations of the solution that include over 16,000 comparisons of his estimates from real aggregate data to the known individual-level answer. The method works in practice.

King's solution to the ecological inference problem will enable empirical researchers to investigate substantive questions that have heretofore proved unanswerable, and move forward fields of inquiry in which progress has been stifled by this problem.

While most people find it relatively easy to manage their possessions, some find it extremely difficult. If you have a problem resisting the urge to acquire and you find your home cluttered and filled to capacity with items many people would find useless and unnecessary, you may suffer from a condition known as hoarding disorder. Hoarding is a behavioral problem consisting of clutter, difficulty discarding items, and excessive buying or acquiring. Hoarding is often associated with significant reduction in quality of life, and in extreme cases, it can pose serious health risks. If you or a loved one has hoarding disorder, this book can help. This fully updated Second Edition of Buried in Treasures outlines a scientifically based, effective program for helping those with hoarding disorder dig their way out of the clutter and chaos of their homes. Written by scientists and practioners who are leaders in studying and treating hoarding disorder, this book outlines a program of skill-building, learning to think about possessions in a different way, and gradual challenges to help people manage their clutter and their lives. It also provides useful information for family and friends of people who hoard, as they struggle to understand and help. Discover the reasons for your problems with acquiring, saving, and hoarding, and learn new ways of thinking about your possessions so you can decide what you really need and what you can do without. Learn to identify the "bad guys" that cause and maintain your hoarding behavior and meet the "good guys" who can help motivate you and put you on the path to change. Useful self-assessments will help you determine the severity of your problem. Training exercises, case examples, organizing tips, and motivation boosters help change the way you think and behave toward your possessions. This book provides easy-to-understand strategies and techniques that anyone can use.

Domestic violence is a pervasive problem in our society that has only recently come to be acknowledged in public discussion. Though many see it as a social and political problem grounded in unequal gender roles, this level of analysis fails to explain adequately why many battered women return to their abusers despite intense suffering and the certainty of more physical violence.

The Illusion of Love challenges the prevailing model, which views the victim of abuse as a normal woman who is unable to escape from her batterer due to the effects of terror and psychological collapse. Instead, David Celani offers a new answer--that women who are battered have a fundamental attraction to partners who are abusive.

Based on his years of clinical experience treating battered women, Celani applies object relations theory and case examples from his own practice to show that many women--and indeed some men--are unconsciously drawn to abusive partners because of personality disorders caused by childhood abuse and neglect. He argues that any effective treatment for battered women must help unravel futile and self-defeating patterns, such as ones that spring from fears of abandonment and fascination with men who produce exaggerated promises of love followed by extreme rejecting behaviors.

"The Illusion of Love" examines the personalities of abusers as well, many of whom suffer from narcissism, a disorder that is also often associated with childhood abuse and neglect. Narcissistic men lash out violently in an attempt to control their own fears or abandonment and to compensate for unsatisfied emotional needs.

Celani concludes that domestic violence is often the tragic result of a union between individuals with complementary personality disorders. His findings fly in the face of the politically correct refusal to examine the behavior of the victim of abuse, a strategy that has led to a severe misunderstanding of the dynamics of the battering scenario. "The Illusion of Love" calls for primary prevention of neglectful parenting to stem the tide of abuse in the future, offering tangible hope for the treatment of victims of abuse as they attempt to extricate themselves from unhealthy, damaging relationships.

'Smart, engaging and funny. It will make you question everything you think you know about what you want' Caroline Criado Perez, author of Invisible Women Be ambitious; find everlasting love; look after your health ... There are countless stories about how we ought to live our lives. These narratives can make our lives easier, and they might sometimes make us happier too. But they can also trap us and those around us. In Happy Ever After, bestselling happiness expert Professor Paul Dolan draws on a variety of studies ranging over wellbeing, inequality and discrimination to bust the common myths about our sources of happiness. He shows that there can be many unexpected paths to lasting fulfilment. Some of these might involve not going into higher education, choosing not to marry, rewarding acts rooted in self-interest and caring a little less about living forever. By freeing ourselves from the myth of the perfect life, we might each find a life worth living.

Compulsory voting is widely used in the democratic world, and it is well established that it increases electoral participation. Beyond Turnout: How Compulsory Voting Shapes Citizens and Political Parties assesses the effects of compulsory voting beyond turnout. Singh first summarizes the normative arguments for and against compulsory voting, provides information on its contemporary use, reviews recent events pertaining to its (proposed) adoption and abolition, and provides an extensive account of extant research on its consequences. He then advances a theory that compulsory voting polarizes behavior and attitudes, and broadens gaps in political sophistication levels, among those with negative and positive orientations toward democracy. Recognizing the impact of mandatory voting on the electorate, political parties then alter the ways in which they seek votes, with mainstream parties moderating their platforms and smaller parties taking more extreme positions. Singh uses survey data from countries with compulsory voting to show that support for the requirement to vote is driven by individuals' orientations toward democracy. The theory is then comprehensively tested using: cross-national data; cross-cantonal data from Switzerland; and survey data from Argentina. Empirical results are largely indicative of the theorized process whereby compulsory voting has divergent effects on citizens and political parties. The book concludes with a discussion of future directions for academic research, implications for those who craft electoral policy, and alternative ways of boosting turnout.
