If sound policy is to be made on the issue of marijuana in the workplace, all available empirical evidence about its impact on job performance should be utilized in the decision process. Although a substantial amount of relevant research has been done, the results published in journals in widely divergent fields, are not easily summarized and present no single, simple message for decision makers. Schwenk and Rhodes offer a unique review of this complex body of work and challenge the many highly publicized but scientifically unsound mythical numbers touted as supporting various policy options. The authors provide a clear and objective presentation to managers on how to evaluate the evidence for themselves and make sound decisions for their own organizations. Scrupulously unbiased in its choice of material, the book will be an essential resource for organizational and public policy makers, and for university students and their teachers.

The effect of marijuana on job performance has been widely accepted as harmful--but is it? Congress thought so, and in 1988, used productivity losses which it attributed to marijuana and other drugs to justify passage of legislation initiating a mandate for a drug-free workplace. Additional legislation expanding this mandate followed and a high percentage of large corporations and an increasing number of small businesses now expend scarce resources on anti-drug programs. Schwenk and Rhodes remain neutral in the debate over workplace drug policies, but argue that policy should be informed by empirical research on the impact of marijuana on job performance. Their book is both a challenge to the mythical numbers so often publicized as supporting a particular advocate's vested position, and a guide to both practitioners and scholars to help them evaluate the diverse body of existing evidence and the claims made by those committed to given policy positions.

Schwenk and Rhodes reprint examples of high quality research previously published in major journals in the fields of psychology, anthropology, economics and medicine. Reviewing and summarizing existing findings, the authors relate these findings to the decision situations faced by policy-makers in the private and public sectors. While the book refuses to endorse any decision outcome with regard to marijuana and the workplace, it makes strong recommendations about the DEGREESIprocesses DEGREESR that should be used in selecting those outcomes. It provides guidelines for evaluating policy-relevant social scientific evidence and discusses the role such evidence can and should play in policy-making. The book shows that contrary to widely held beliefs, very little evidence that the substance has a consistent negative effect on worker productivity. Though social science does not show that resources devoted to creating a drug-free workplace are likely to pay off economically, the authors stress that the implications of this fact for corporate and government decisions are not cut and dried, but depend on the decision rules and the policy goals selected by policy-makers. This book will be an essential tool for managers, scholars, and anyone trying to make sense of the complicated and confusing maze of data and arguments surrounding this divisive issue.

The enneagram is a geometric figure most well-known for its ability to describe nine personality types. But we can also use the enneagram to understand our relationships with other people and to discover why different types are attracted to different transformational paths.

As a reporter for the "The Enneagram Monthly," I've written many articles on the enneagram. From the beginning, I've focused on the assets of the nine types rather than their liabilities--a focus that powerfully informs my first two books, "The Positive Enneagram" and "Archetypes of the Enneagram."

I was attracted to Ken Wilber's Integral Operating System (IOS) because it also emphasizes the positive role played by ego/personality development in transformational work. Wilber has been developing his ideas for 40 years and has published more than 25 books on transformation.

The more I studied IOS and the enneagram, the more I realized the incredible potential each has to inform the other. After writing articles on the two systems for five years, I knew there was enough material for a book--and "The Integral Enneagram" was born.

The book is has three parts:

Part I provides a brief but easy-to-follow description of both systems (the enneagram and IOS). It also introduces the unifying theme of the book: that each of us has a unique calling or "dharma" in life, a calling that is partially revealed by our enneagram type. To discover the "dharma" is to find the path that transforms us through service to life.

Part II describes two ways of working with the enneagram. The " personality enneagram" focuses on the nine personality points of view, each of which represents a unique approach to living. The "process enneagram" portrays the same nine enneagram points as nine stages in a transformational process. The two can be interwoven to create an Integral Enneagram model that can help us see why different kinds of people are attracted to different transformational paths and practices.

Part III integrates the Integral Enneagram model with Wilber's Integral Operating System, to the mutual enhancement of both. It especially highlights the value of a more feminine, embodied approach to transformation, the importance of process (not just progress) in inner work, and how to develop our consciousness in a way that sparks our creativity.

"The Integral Enneagram" is a unique book with an approach not presented elsewhere--an approach that not only supports our individual development but our ability to use whatever we develop to come into union with the greater purposes of life.

"The Positive Enneagram: A New Approach to the Nine Personality Types," introduces a new way of working with the enneagram, a system that describes nine core motivations that shape our lives in profound ways. Each of us is particularly influenced by the energy of one of these types. So determining our main type can enhance self-understanding, improve our relationships, and help us find direction in life. The book is packed with information. It succinctly describes the enneagram types, subtypes, wing types, energy centers, and connecting points; most chapters include easy-to-read charts and illustrations summarizing key points. The last two chapters are particularly innovative: one demonstrates how to link the personality and process enneagrams; the other focuses on ways to use the enneagram to become more integrated, creative, and attuned. The appendix includes three tests: two for determining type and one for determining subtype. But "The Positive Enneagram" does more than simply describe the types. It describes them in a way that makes a persuasive case for seeing them in a positive light (more as "energy types" than "ego types"). It's this dynamic, energy-focused approach that makes the book unique-and that gives it a freshness that will appeal to a variety of readers.

"What is my path in life?" That s something we all want to know. The enneagram can help us find the answer because it reveals the nine key sources of motivation that give rise to human behavior. While these nine patterns of motivation are usually equated with personality types (or even as ego types that hamper our spiritual evolution), Susan Rhodes sees them nine dynamic archetypes that help us fulfill our destiny, dharma, or calling in life. In her first book, "The Positive Enneagram," she describes the nine types from an affirmative and non-dualistic perspective. In "Archetypes of the Enneagram," she goes further, illuminating the fascinating world of the 27 enneagram subtypes, using examples from film, TV, and real life. But she also delves more deeply into the nature of the enneagram, the nine types, and the subtypes, providing a Jungian-based model for enneagram work--a model in which the 27 subtypes become 27 paths to individuation. Comprehensive, provocative, and original, "Archetypes of the Enneagram" is the kind of book that invites readers to embark on their own journey of self-discovery.
