دانلود کتاب Evaluating AIDS Prevention Programs: Expanded Edition

With insightful discussion of program evaluation and the efforts of the Centers for Disease Control, this book presents a set of clear-cut recommendations to help ensure that the substantial resources devoted to the fight against AIDS will be used most effectively. This expanded edition of ''Evaluating AIDS Prevention Programs'' covers evaluation strategies and outcome measurements, including a realistic review of the factors that make evaluation of AIDS programs particularly difficult. Randomized field experiments are examined, focusing on the use of alternative treatments rather than placebo controls. The book also reviews nonexperimental techniques, including a critical examination of evaluation methods that are observational rather than experimental - a necessity when randomized experiments are infeasible.
