Скачать книгу - When Humans Nearly Vanished - The Catastrophic Explosion of the Toba Volcano (Unabridged)



Some 73,000 years ago, the Mount Toba supervolcano in today's Indonesia erupted, releasing the energy of a million tons of explosives. So much ash and debris was injected into the stratosphere that it partially blocked the sun's radiation and caused global temperatures to drop for a decade. In this book, Donald R. Prothero presents the controversial argument that the Toba catastrophe nearly wiped out the human race, leaving only about a thousand to ten thousand breeding pairs of humans worldwide. Human genes today show evidence of a "genetic bottleneck,? an effect seen when a population of organisms becomes so small that their genetic diversity is greatly reduced. This group of survivors could be the ancestors of all humans alive today. Prothero explores the geological and biological evidence supporting the Toba bottleneck theory, revealing how the explosion itself was discovered and offering insight into how the world changed afterward and what might happen if such an eruption occurred today.

The 27 Challenges Managers Face. Step-by-Step Solutions to (Nearly) All of Your Management Problems The 27 Challenges Managers Face. Step-by-Step Solutions to (Nearly) All of Your Management Problems

Автор: Bruce Tulgan

Год издания: 

For more than twenty years, management expert Bruce Tulgan has been asking, “What are the most difficult challenges you face when it comes to managing people?” Regardless of industry or job title, managers cite the same core issues—27 recurring challenges: the superstar whom the manager is afraid of losing, the slacker whom the manager cannot figure out how to motivate, the one with an attitude problem, and the two who cannot get along, to name just a few. It turns out that when things are going wrong in a management relationship, the common denominator is almost always unstructured, low substance, hit-or-miss communication. The real problem is that most managers are “managing on autopilot” without even realizing it—until something goes wrong. And if you are managing on autopilot, then something almost always does. The 27 Challenges Managers Face shows exactly how to break the vicious cycle and gain control of management relationships. No matter what the issue, Tulgan shows that the fundamentals are all you need. The very best managers hold ongoing one-on-one conversations that make expectations clear, track performance, offer feedback, and hold people accountable. For every workplace problem—even the most awkward and difficult—The 27 Challenges Managers Face shows how to tailor conversations to solve situations familiar to every manager. Tulgan offers clear approaches for turning around bad attitudes, reducing friction and conflict, improving low performers, retaining top performers, and even addressing your own personal burnout. The 27 Challenges Managers Face is an indispensable resource for managers at all levels, one anyone managing anyone will want to keep on hand. One challenge at a time, you’ll see how the most effective managers use the fundamentals of management to proactively resolve (nearly) any problem a manager could face.
