Book Description
In 1975, Congress relieved the Secretary of Transportation of the power to impose sanctions upon states for not having a law requiring the use of helmets by motorcyclists. Shortly afterward, the states having such laws began repealing or modifying them. This report reviews the available literature on the subject of mandatory motorcycle helmet legislation, and presents the results of a survey of states that have repealed their laws. From the information available, it was determined that the use of motorcycle helmets reduces the incidence of serious and fatal head injury among motorcyclists without interfering with their ability to operate their vehicles safely. Additionally, it was determined that the mandatory motorcycle helmet laws are constitutional and that they have the support of both the general public and motorcyclists in Virginia.

Book Description
Leading social research methodologists and evaluators explore research design issues in this second of two volumes inspired by the work of Donald Campbell and sponsored by the American Evaluation Association. The authors address such issues as quasi-experimentation, the proper conduct of social inquiry, ways to take account of threats to validity, plausible rival hypotheses in measurement and design, subject selection and loss in randomized experiments, the use of evaluation to assess the validity of computer simulations, method variance, and time series experiments. Applied researchers who want to improve their research designs will find this book a compelling and thought-provoking read.
