7 Lenses

7 Lenses has an important purpose - to provide a clear, actionable road map for leading ethically in a complex world. With a Foreword by Stephen M. R. Covey, this book takes us beyond the triple bottom line to 7 different perspectives on ethical leadership, and provides 14 Guiding Principles that help us honor them all in daily leadership. It answers: Why do even the ethics experts disagree about what ethical leadership means? What is the bigger picture that we should use as our leadership road map? What are the business benefits of intentionally using high-level ethical leadership? What can we do to be prepared for the future of ethical leadership? The examples, graphics, cases and questions provide a framework for deeply engaging constituents and building trust for the long term.

The Basic Bookshelf for Eyecare Professionals is a series that provides fundamental and advanced material with a clinical approach to clinicians and students. A special effort was made to include information needed for the certification exams in ophthalmic and optometric assisting, as well as for surgical assistants, opticians, plus low vision, and contact lens examiners. Perfect for the optometric and ophthalmic tech, this well-illustrated text includes detailed how-to's that will make contact lens fitting and patient education easy. The author starts with ocular anatomy and how it is affected by contact lens wear. Other topics include lens design and materials, patient selection and examination procedures, and fitting of both soft and rigid lenses (including astigmatic designs).

Presents readers with the basic science, technology, and applications for every type of adaptive lens An adaptive lens is a lens whose shape has been changed to a different focal length by an external stimulus such as pressure, electric field, magnetic field, or temperature. Introduction to Adaptive Lenses is the first book ever to address all of the fundamental operation principles, device characteristics, and potential applications of various types of adaptive lenses. This comprehensive book covers basic material properties, device structures and performance, image processing and zooming, optical communications, and biomedical imaging. Readers will find homework problems and solutions included at the end of each chapter—and based on the described device structures, they will have the knowledge to fabricate adaptive lenses for practical applications or develop new adaptive devices or concepts for advanced investigation. Introduction to Adaptive Lenses includes chapters on: Optical lenses Elastomeric membrane lenses Electro-wetting lenses Dielectrophoretic lenses Mechanical-wetting lenses Liquid crystal lenses This is an important reference for optical engineers, research scientists, graduate students, and undergraduate seniors.

A detailed and comprehensive account of the engineering of the world’s first nonimaging Fresnel lens solar concentrator. The book closes a gap in solar concentrator design, and describes nonimaging refractive optics and its numerical mathematics. The book shows the reader how to find his or her own optical solution using the rules and methodologies covering the design and the assessment of the nonimaging lens.

With its implications for health care, the economy, and an assortment of other policy areas, population aging is one of the most pressing issues facing governments and society today, and confronting its complex reality is becoming increasingly urgent, particularly in the age of COVID-19. In The Four Lenses of Population Aging, Patrik Marier looks at how Canada’s ten provinces are preparing for an aging society. Focusing on a wide range of administrative and policy challenges, this analysis explores multiple actions from the development of strategic plans to the expansion of long-term care capacity. To enhance this analysis, Marier adopts four lenses: the intergenerational, the medical, the social gerontological, and the organizational. By comparing the unique insights and contributions of each lens, Marier draws attention to the vital lessons and possible solutions to the challenges of an aging society. Drawing on over a hundred interviews with senior civil servants and thousands of policy documents, The Four Lenses of Population Aging is a significant contribution to public administration, provincial politics, and comparative public policy literatures, and a timely resource for policymakers and general readers seeking an informed perspective on a timely and important issue.
