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.

Deciding what lens to buy is complex: What are the ‘pros and cons’ of choosing a zoom lens over a series of single focal length (prime) lenses? Is a long zoom lens a better choice than two shorter zooms? Is it worth paying more for a lens with a wider maximum aperture? Can third-party lenses be a good choice? How about lens adaptors and teleconverters? Lenses Guide outlines some of the technological basics of today’s lenses – the varying mounts and formats, image stabilisation and focusing systems, image sensor size – and their impact on lens performance. It then looks at various categories of lenses: standard kit lenses; telephoto kit lenses; and ‘all-in-one’ extended zoom lenses. This is followed by a series of chapters exploring lenses and different types of photography – landscapes, portraiture, sports and wildlife, and macro photography – along with techniques to improve picture-taking. With lenses at anything from $300 to $3000 and beyond, this guide might be the best lens investment you ever make!
This book summarizes current understanding of the scientific, clinical, and technical issues surrounding the use of contact lenses. It discusses the special occupational conditions experienced by military personnel, particularly in extreme environments, that give rise to the question of whether or not to use contact lenses. Experts in optometry, ophthalmology, visual psychophysics, and engineering describe recent developments in design and use; and representatives of the military services provide examples of actual situations in aerospace settings. Considerations in Contact Lens Use Under Adverse Conditions will be of particular interest to those involved in the design of contact lenses and those responsible for occupational safety and health matters in the private sector.
