Sommario/riassunto

Covering more than seven percent of the earth's surface, sea ice is crucial to the functioning of the biosphere-and is a key component in our attempts to understand and combat climate change. With On Sea Ice, geophysicist W. F. Weeks delivers a natural history of sea ice, a fully comprehensive and up-to-date account of our knowledge of its creation, change, and function.             The volume begins with the earliest recorded observations of sea ice, from 350 BC, but the majority of its information is drawn from the period after 1950, when detailed study of sea ice became widespread.

Sommario/riassunto

What makes an effective executive?The measure of the executive, Peter F. Drucker reminds us, is the ability to "get the right things done." This usually involves doing what other people have overlooked as well as avoiding what is unproductive. Intelligence, imagination, and knowledge may all be wasted in an executive job without the acquired habits of mind that mold them into results.Drucker identifies five practices essential to business effectiveness that can, and must, be learned:Managing timeChoosing what to contribute to the organizationKnowing where and how to mobilize strength for best effectSetting the right prioritiesKnitting all of them together with effective decision-makingRanging widely through the annals of business and government, Peter F. Drucker demonstrates the distinctive skill of the executive and offers fresh insights into old and seemingly obvious business situations.
