"Among the most influential models in contemporary behavioral science, self-determination theory (SDT) offers a broad framework for understanding the factors that promote human motivation and psychological flourishing. In this authoritative work, SDT cofounders Richard M. Ryan and Edward L. Deci systematically review the theory's conceptual underpinnings, empirical evidence base, and practical applications across the lifespan. Ryan and Deci demonstrate that supporting people's basic needs for competence, relatedness, and autonomy is critically important for virtually all aspects of individual and societal functioning."--Jacket.

As I begin to write this Preface, I feel a rush of excitement. I have now finished the book; my gestalt is coming into completion. Throughout the months that I have been writing this, I have, indeed, been intrinsically motivated. Now that it is finished I feel quite competent and self-determining (see Chapter 2). Whether or not those who read the book will perceive me that way is also a concern of mine (an extrinsic one), but it is a wholly separate issue from the intrinsic rewards I have been experiencing. This book presents a theoretical perspective. It reviews an enormous amount of research which establishes unequivocally that intrinsic motivation exists. Also considered herein are various approaches to the conceptualizing of intrinsic motivation. The book concentrates on the approach which has developed out of the work of Robert White (1959), namely, that intrinsically motivated behaviors are ones which a person engages in so that he may feel competent and self-determining in relation to his environment. The book then considers the development of intrinsic motiva tion, how behaviors are motivated intrinsically, how they relate to and how intrinsic motivation is extrinsically motivated behaviors, affected by extrinsic rewards and controls. It also considers how changes in intrinsic motivation relate to changes in attitudes, how people attribute motivation to each other, how the attribution process is motivated, and how the process of perceiving motivation (and other internal states) in oneself relates to perceiving them in others.

The Power of Determination tells the stories of fourteen people who carry the following belief in their hearts: I have taken charge of my life. I am determined to do what is needed to grow and succeed in this world. I will let nothing stop me. In the face of obstacles, I will persist. when I get knocked down, I'll get back up. I believe in the words of Muhammad Ali: I hated every minute of training, but I said, 'Don't quit. Suffer now and live the rest of your life as a champion.'" Read these inspiring stories--of Maria, Paul, Erika, Jeroboam, Tay Thi, Indonesia and Ericka, Peter, Melissa, Suashunn, Tricia, Richard, Crystal, Juan, and Amanda--to increase your own resolve to pursue your dreams and live a proud and determined life.

Over the past twenty years an increasing number of researchers from various universities have been investigating motivational issues underlying the self-regulation of behavior. Using either Self-Determination Theory or closely related theoretical perspectives, these researchers have performed laboratory experiments, as well as field studies in a variety of real-world settings. In April 1999 thirty of these researchers convened at the University of Rochester to present their work, share ideas, and discuss future research directions. This book is an outgrowth of that important and fascinating conference. It summarizes the research programs of these social, personality, clinical, developmental, and applied psychologists who have a shared belief in the importance of self-determination for understanding basic motivational processes and for solving pressing real-world problem.

A comprehensive approach to sample size determination and power with applications for a variety of fields Sample Size Determination and Power features a modern introduction to the applicability of sample size determination and provides a variety of discussions on broad topics including epidemiology, microarrays, survival analysis and reliability, design of experiments, regression, and confidence intervals. The book distinctively merges applications from numerous fields such as statistics, biostatistics, the health sciences, and engineering in order to provide a complete introduction to the general statistical use of sample size determination. Advanced topics including multivariate analysis, clinical trials, and quality improvement are addressed, and in addition, the book provides considerable guidance on available software for sample size determination. Written by a well-known author who has extensively class-tested the material, Sample Size Determination and Power: Highlights the applicability of sample size determination and provides extensive literature coverage Presents a modern, general approach to relevant software to guide sample size determination including CATD (computer-aided trial design) Addresses the use of sample size determination in grant proposals and provides up-to-date references for grant investigators An appealing reference book for scientific researchers in a variety of fields, such as statistics, biostatistics, the health sciences, mathematics, ecology, and geology, who use sampling and estimation methods in their work, Sample Size Determination and Power is also an ideal supplementary text for upper-level undergraduate and graduate-level courses in statistical sampling.

In this book, leading scholars re-examine the principle of national self-determination from diverse theoretical perspectives.
