Book Description
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.

Book Description
This book is an accessible, practical and comprehensive guide for researchers from multiple disciplines including biomedical, epidemiology, engineering and the social sciences. Written for accessibility, this book will appeal to students and researchers who want to understand the basics of survival and event history analysis and apply these methods without getting entangled in mathematical and theoretical technicalities. Inside, readers are offered a blueprint for their entire research project from data preparation to model selection and diagnostics. Engaging, easy to read, functional and packed with enlightening examples, ‘hands-on’ exercises, conversations with key scholars and resources for both students and instructors, this text allows researchers to quickly master advanced statistical techniques. It is written from the perspective of the ‘user’, making it suitable as both a self-learning tool and graduate-level textbook. Also included are up-to-date innovations in the field, including advancements in the assessment of model fit, unobserved heterogeneity, recurrent events and multilevel event history models. Practical instructions are also included for using the statistical programs of R, STATA and SPSS, enabling readers to replicate the examples described in the text.

Book Description
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.

Book Description
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.

Book Description
This book examines issues concerning how developing countries will have to prepare for demographic and epidemiologic change. Much of the current literature focuses on the prevalence of specific diseases and their economic consequences, but a need exists to consider the consequences of the epidemiological transition: the change in mortality patterns from infectious and parasitic diseases to chronic and degenerative ones. Among the topics covered are the association between the health of children and adults, the strong orientation of many international health organizations toward infant and child health, and how the public and private sectors will need to address and confront the large-scale shifts in disease and demographic characteristics of populations in developing countries.

Book Description
Transitions and Social Change: The Early Lives of American Men deals with the timing and synchronization of transition events that signify the passage of American males from adolescence to adulthood. The book is divided into four parts. Part I is an introduction to the study and its data and methods. This part also deals with the passage to adulthood, education, work, and adolescence. Part II covers the intercohort differences in the transition to adulthood. Part III studies the effects of social background differentials such as social class background, the size of the community, and ethnic ancestry to the transition to adulthood. Part IV talks about the possible consequences of early life-course transition behavior, transition to adulthood and marital stability, and social change and the transition to adulthood. The text is recommended for anthropologists, sociologists, psychologists, and any experts in the field who wish to know more about the transition of American adolescent males into adulthood, the factors that affect it, and its effects.
