Multi-State Survival Models for Interval-Censored Data introduces methods to describe stochastic processes that consist of transitions between states over time. It is targeted at researchers in medical statistics, epidemiology, demography, and social statistics. One of the applications in the book is a three-state process for dementia and survival in the older population. This process is described by an illness-death model with a dementia-free state, a dementia state, and a dead state. Statistical modelling of a multi-state process can investigate potential associations between the risk of moving to the next state and variables such as age, gender, or education. A model can also be used to predict the multi-state process. The methods are for longitudinal data subject to interval censoring. Depending on the definition of a state, it is possible that the time of the transition into a state is not observed exactly. However, when longitudinal data are available the transition time may be known to lie in the time interval defined by two successive observations. Such an interval-censored observation scheme can be taken into account in the statistical inference. Multi-state modelling is an elegant combination of statistical inference and the theory of stochastic processes. Multi-State Survival Models for Interval-Censored Data shows that the statistical modelling is versatile and allows for a wide range of applications.

Survival analysis is a highly active area of research with applications spanning the physical, engineering, biological, and social sciences. In addition to statisticians and biostatisticians, researchers in this area include epidemiologists, reliability engineers, demographers and economists. The economists survival analysis by the name of duration analysis and the analysis of transition data. We attempted to bring together leading researchers, with a common interest in developing methodology in survival analysis, at the NATO Advanced Research Workshop. The research works collected in this volume are based on the presentations at the Workshop. Analysis of survival experiments is complicated by issues of censoring, where only partial observation of an individual's life length is available and left truncation, where individuals enter the study group if their life lengths exceed a given threshold time. Application of the theory of counting processes to survival analysis, as developed by the Scandinavian School, has allowed for substantial advances in the procedures for analyzing such experiments. The increased use of computer intensive solutions to inference problems in survival analysis~ in both the classical and Bayesian settings, is also evident throughout the volume. Several areas of research have received special attention in the volume.

A New York Times bestseller! A pioneering and timely study of how to navigate life's biggest transitions with meaning, purpose, and skill Bruce Feiler, author of the New York Times bestsellers The Secrets of Happy Families and Council of Dads, has long explored the stories that give our lives meaning. Galvanized by a personal crisis, he spent the last few years crisscrossing the country, collecting hundreds of life stories in all fifty states from Americans who’d been through major life changes—from losing jobs to losing loved ones; from changing careers to changing relationships; from getting sober to getting healthy to simply looking for a fresh start. He then spent a year coding these stories, identifying patterns and takeaways that can help all of us survive and thrive in times of change. What Feiler discovered was a world in which transitions are becoming more plentiful and mastering the skills to manage them is more urgent for all of us. The idea that we’ll have one job, one relationship, one source of happiness is hopelessly outdated. We all feel unnerved by this upheaval. We’re concerned that our lives are not what we expected, that we’ve veered off course, living life out of order. But we’re not alone. Life Is in the Transitions introduces the fresh, illuminating vision of the nonlinear life, in which each of us faces dozens of disruptors. One in ten of those becomes what Feiler calls a lifequake, a massive change that leads to a life transition. The average length of these transitions is five years. The upshot: We all spend half our lives in this unsettled state. You or someone you know is going through one now. The most exciting thing Feiler identified is a powerful new tool kit for navigating these pivotal times. Drawing on his extraordinary trove of insights, he lays out specific strategies each of us can use to reimagine and rebuild our lives, often stronger than before. From a master storyteller with an essential message, Life Is in the Transitions can move readers of any age to think deeply about times of change and how to transform them into periods of creativity and growth.

When it was originally released, Thriving in Transitions: A Research-Based Approach to College Student Success represented a paradigm shift in the student success literature, moving the student success conversation beyond college completion to focus on student characteristics that promote high levels of academic, interpersonal, and intrapersonal performance in the college environment. The authors contend that a focus on remediating student characteristics or merely encouraging specific behaviors is inadequate to promote success in college and beyond. Drawing on research on college student thriving completed since 2012, the newly revised collection presents six research studies describing the characteristics that predict thriving in different groups of college students, including first-year students, transfer students, high-risk students, students of color, sophomores, and seniors, and offers recommendations for helping students thrive in college and life. New to this edition is a chapter focused on the role of faculty in supporting college student thriving.

This book presents statistical methods for analysis of the duration of events. The primary focus is on models for single-spell data, events in which individual agents are observed for a single duration. Some attention is also given to multiple-spell data. The first part of the book covers model specification, including both structural and reduced form models and models with and without neglected heterogeneity. The book next deals with likelihood based inference about such models, with sections on full and semiparametric specification. A final section treats graphical and numerical methods of specification testing. This is the first published exposition of current econometric methods for the study of duration data.

Cardiac arrest can strike a seemingly healthy individual of any age, race, ethnicity, or gender at any time in any location, often without warning. Cardiac arrest is the third leading cause of death in the United States, following cancer and heart disease. Four out of five cardiac arrests occur in the home, and more than 90 percent of individuals with cardiac arrest die before reaching the hospital. First and foremost, cardiac arrest treatment is a community issue - local resources and personnel must provide appropriate, high-quality care to save the life of a community member. Time between onset of arrest and provision of care is fundamental, and shortening this time is one of the best ways to reduce the risk of death and disability from cardiac arrest. Specific actions can be implemented now to decrease this time, and recent advances in science could lead to new discoveries in the causes of, and treatments for, cardiac arrest. However, specific barriers must first be addressed. Strategies to Improve Cardiac Arrest Survival examines the complete system of response to cardiac arrest in the United States and identifies opportunities within existing and new treatments, strategies, and research that promise to improve the survival and recovery of patients. The recommendations of Strategies to Improve Cardiac Arrest Survival provide high-priority actions to advance the field as a whole. This report will help citizens, government agencies, and private industry to improve health outcomes from sudden cardiac arrest across the United States.
