Project Disclosure

Anyone interested in UFO phenomena will be captivated by this extensive account of the history of UFO sightings and what can happen once the existence of aliens on Earth is finally revealed, an event the authors feel is sure to happen very soon. Authors Dolan and Zabel, both respected UFOlogists, detail what will happen A.D. (After Disclosure) including how both governments and people will respond to the confirmation that we are not alone in the universe. This book is a goose bump-raising thrill ride, one sure to provoke thought, spark debate, and entertain in equal measure.

Some mysteries from ancient times have yet to be solved, such as how the ancient Egyptians constructed the Great Pyramid with such mathematical accuracy. Other enigmas are much more recent, such as twentieth-century UFO sightings and alleged alien abductions, as well as the possible existence of top-secret government files relating to these events. Some think that these strange phenomena have been covered up by a government conspiracy. This set explores how and why these beliefs may have come about. Features include: Interviews, quotations, and testimonies are presented in an engaging narrative that allows students to describe the relationship between a series of events or concepts. Documentation that includes photographs and reports to help students locate information relevant to a given topic efficiently.

Statistical disclosure control is the discipline that deals with producing statistical data that are safe enough to be released to external researchers. This book concentrates on the methodology of the area. It deals with both microdata (individual data) and tabular (aggregated) data. The book attempts to develop the theory from what can be called the paradigm of statistical confidentiality: to modify unsafe data in such a way that safe (enough) data emerge, with minimum information loss. This book discusses what safe data, are, how information loss can be measured, and how to modify the data in a (near) optimal way. Once it has been decided how to measure safety and information loss, the production of safe data from unsafe data is often a matter of solving an optimization problem. Several such problems are discussed in the book, and most of them turn out to be hard problems that can be solved only approximately. The authors present new results that have not been published before. The book is not a description of an area that is closed, but, on the contrary, one that still has many spots awaiting to be more fully explored. Some of these are indicated in the book. The book will be useful for official, social and medical statisticians and others who are involved in releasing personal or business data for statistical use. Operations researchers may be interested in the optimization problems involved, particularly for the challenges they present. Leon Willenborg has worked at the Department of Statistical Methods at Statistics Netherlands since 1983, first as a researcher and since 1989 as a senior researcher. Since 1989 his main field of research and consultancy has been statistical disclosure control. From 1996-1998 he was the project coordinator of the EU co-funded SDC project.
