Smith explains that a theory of change in the social sector is roughly equivalent to a combination of the business model and strategy in the for-profit world. You need to identify a change and have a hypothesis about how to make it happen, she says. This is more complex in the social sector because, in additional to market forces, you have to deal with regulatory forces, emotional forces, social forces, and political forces, she adds. A se...more

The numbers are stacked against the inspired business owner-to-be. Seasoned angel investors Ron Conway and Mike Maples talk about how many ideas they receive, how many executive summaries they peruse, how many meetings they call, and the shockingly few ventures - roughly one out of 150 - that end up receiving their investment of time and money. Also, Conway points out that investing is a risky business, with an even split between those t...more

He describes in detail the effort of the Athenians to create a system of justice that would not only minimize tampering, in order to insure justice, but also maximize citizen participation. After this discussion, Professor Kagan comments on the role of women in Athens by looking at two types of sourc...more

This lecture begins by applying the united-atom "plum-pudding" view of molecular orbitals, introduced in the previous lecture, to more complex molecules. It then introduces the more utilitarian concept of localized pairwise bonding between atoms. Formulating an atom-pair molecular orbital as the sum of atomic orbitals creates an electron difference density through the cross product that enters upon squaring a sum. This "overlap" term is th...more

Sheer brainpower, strength in numbers, and good old fashioned networking is how the nature of world influence is established. Skewed and disproportionate, modern power structures that regulate global problems happen only when the elite meet, says author David Rothkopf. And decisions made based on these meetings often do not adequately represent the people or the interests that they are meant to serve.

There are several ways to examine the behaviors of organisms when they forage or hunt for food or mates. These behaviors become more complex in higher organisms, such as primates and whales, which can hunt in groups. Foragers and hunters have been shown to examine the marginal cost and marginal benefit of continuing an action and then adjust their behaviors accordingly. They are also able to handle risk by hoarding resources.

Hunter-gatherer populations were much less dense than later agriculturalists. The variety of their food supply protected them from crop failures and their sparseness reduced the spread of infectious diseases. Hunter-gatherers were healthier and worked less than early agriculturalists. Why didn't their numbers increase up to the same level of Malthusian misery? Their numbers may have been limited by violence between groups. Agriculture is m...more
