The purpose of this book is to place computer simulation studies within the paradigm of intervention research that is concerned with comparing the outcomes of health care delivered under different policies. This book presents computer simulation as a tool for testing various policy alternatives that have been developed by decision-makers within health care systems. This approach differs from the use of computer simulation in operations research, where simulation helps determine the configurations of a system that will allow it to function optimally. Although simulation of health care processes is not new, few health care systems have used simulations as a basis for re-engineering the delivery of health services. There is growing appreciation that the complexity of health care processes exceeds the capacity of individual disciplines–health services research, health economics, or operations research–to guide health care reform. In this book, the authors focus on bringing the methodological rigor of evaluative research to the design and analysis of such simulation studies. The book is intended as a reference for health services researchers. It offers a comprehensive description of the methodology of conducting simulation studies in evaluation of service alternatives in surgical care using discrete-event models, including the steps for identifying the clinical and managerial activities of the perioperative process, determining the model requirements, implementing simulation models, designing simulation experiments and analyzing the experimental data, and interpreting and reporting results. The book also offers examples of specific aspects of conducting simulation experiments: how to determine the number of runs needed to estimate the effect of implementing a health care policy; how to allocate the number of runs to study groups in simulation experiments aiming to evaluate policy or management alternatives; and how to use statistical analysis toestimate, interpret, and report effect sizes.

In A Land Between Worlds, poet and photographer John Mack shares his vision on that part of the human condition which brings about our disconnection from nature, its further disconnection through smart devices, and provides clues that might lead us back to our natural unity with it. Covering nearly fifty of the most iconic U.S. National Parks, Mack uses poetry, landscape photography, and an interactive augmented reality app to invite us into a deep conversation about the encroaching digital landscape, our attachments to it, and the uncertain fate of our nature. After a four-year journey-flying more than 300,000 air-miles aboard over 200 flights, driving over 15,000 miles with the aid of over 25 car rentals, including hiking over 220 miles, 7 helicopter charters, 6 seaplane charters, 8 grizzly sightings, and 1 husky sled-poet and photographer John Mack returns with evidence of some of America's most iconic, natural sites and their current state of deterioration vis a vis the proliferation of smart devices and the encroaching virtual environment. In an attempt to shed light on the current state of our nature, Mack completes what he calls a "reconaissance mission," having crisscrossed the entire United States of America. Covering a land with length from Maine to Hawaii, a depth from the southern bend of Texas to the far reaches of Alaska's arctic circle, A Land Between Worlds shares Mack's vision of who we are in relation to our environment and looks for clues as to whether or not a balance between nature and today's increasingly seductive technology can be attained. Writes Mack, Today's world finds the human caught in a balancing act between technology and nature unlike ever seen before. With the invention of the smartphone, human beings across the planet are increasingly experiencing life through their screens. With the simple click of the on button, what was once intended to serve as a mere tool now serves as our reality. Caught in this maneuver is the fate of the human soul. As artificial as modern technology may seem, history has shown technology to be a natural and essential part of the human journey. Are we reaching a point, however, where this part of the journey might be taking over the journey's entirety? In these modern times of increasing dependence on digital devices, it behooves us to ask ourselves what, exactly, would allow such an overtaking to occur. Are the programmed lenses of the app-environment-gaming, social networking, news, lifestyle-so mesmerizingly colorful as to take precedent over the vibrant colors of life itself? Or, rather, is there a program already running inside our heads-one that first disconnects us from life's vibrance and only then finds us reaching for our screens to restore the vibrance for us? Comprised of gatherings from nearly fifty iconic U.S. National Parks, Mack uses poetry, landscape photography, and an interactive augmented reality app to invite us into a deep introspection about what it means to be human: What, if anything, can our National Parks teach us about the nature within us? A Land Between Worlds is evidence of hope in a world where nature, freedom, love, democracy, and reality itself are under attack. It's interactive juxtaposition of natural sanctuaries and their digital versions reveals the encroaching digital landscape, our attachments to it, and the uncertain fate of our nature. Available in signed, limited collector's editions and standard editions, A Land Between Worlds includes a "making of" video, reminding us of the art of human craft in an ever more digitized world. A Land Between Worlds is the official book of A Species Between Worlds: Our Nature, Our Screens, the exhibition showcased in New York City in January of 2022. The month-long exhibition attracted some of the most influential voices at the forefront of the battle to defend human awareness from the threats that unchecked use of computer-based technologies pose to our humanity. Available in signed, limited collector's editions and standard editions, the poetry book includes not only all of the exhibition's U.S. National Park images but also the project's entire collection of poems, many of which were not on display to the public.

In this clear and straight-forward workbook, the author guides readers through the ten steps of Recapitulation and invites them to experience the powerful and positive new energy that results from healing the wounds of the past.

Millions of readers of Carlos Castaneda books have long enjoyed the fantastic teachings of don Juan Matus, the Yaqui shaman from northern Mexico. Now, thanks to the practical techniques based on Castaneda's writings offered here by author Victor Sanchez--the body as a field of energy, the not-doings of the personal self, stopping the internal dialogue, the magic of attention, setting up dreaming, the warrior's greatest love, and more--you can apply these teachings to your everyday life.
