In this lecture, Professor Shapiro delves into the nuances of MacIntyre's argument, focusing specifically on his Aristotelian account of human psychology. It has two features: (1) man's nature is inherently teleological or purposive, and (2) human behavior is fundamentally other-directed, in that a person's happiness is conditioned upon the experience of others as it relates to him, particularly on the feeling of being valued by someone...more

We analyze three games using our new solution concept, subgame perfect equilibrium (SPE). The first game involves players' trusting that others will not make mistakes. It has three Nash equilibria but only one is consistent with backward induction. We show the other two Nash equilibria are not subgame perfect: each fails to induce Nash in a subgame. The second game involves a matchmaker sending a couple on a date. There are three Nash...more

Professor Blight begins his lecture with a description of the sea change in Civil War scholarship heralded by the Social History revolution of the 1960s and 1970s. Along with a focus on the experience of the common solider, women, and African Americans, a central component of this shift in scholarly emphasis was an increased interest in the effects of the war on the Union and Confederate home fronts. After suggesting some of the ways in...more

In the last decade of the nineteenth century, malariology emerged as the most prestigious and intellectually exciting field in the new discipline of tropical medicine. The disease's complexity and resistance to conventional public health strategies posed a major challenge to doctors and scientists. Plague measures and social hygiene had no effect in curbing malaria, and the disease proved difficult to classify. The case of Italy, and the...more

In this lecture, Professor Kagan examines the continuation of Spartan tyranny over the Greek poleis and the response of the Greek world. According to Professor Kagan, it became clear that the Greek poleis needed to do something to check the power of Sparta. So, Thebes, Argos, Corinth, and Athens along with some of the smaller poleis joined together to fight Sparta in the Corinthian War. The war ended in a stalemate, but now the...more

Reliable records of influenza, dating back to the 1700s, suggest a pattern of one major pandemic every century. Among the pandemics for which there is solid documentary evidence, the outbreak of 1918-1920 is by far the greatest. The so-called Spanish Lady caused somewhere between 25 and 100 million deaths worldwide. It is distinctive both for its high mortality rate, in comparison to other flu pandemics, and for its unusual demographic...more

Professor McBride expands on the recently introduced concept of the wave function by illustrating the relationship of the magnitude of the curvature of the wave function to the kinetic energy of the system, as well as the relationship of the square of the wave function to the electron probability density. The requirement that the wave function not diverge in areas of negative kinetic energy leads to only certain energies being allowed, a...more

Slow down in capital spending has had a profound effect on the enterprise software companies, says Thompson. Symantec has made tremendous investments to retool infrastructure of the company in the last 2 years to scale the business. This story is being replayed time and time again in the valley, he says. With capital spending decreasing, companies are adopting new models - software as a service. There is no right answer and model; it is a...more

Neutral evolution occurs when genes do not experience natural selection because they have no effect on reproductive success. Neutrality arises when mutations in an organism's genotype cause no change in its phenotype, or when changes in the genotype bring about changes in the phenotype that do not affect reproductive success. Because neutral genes do not change in any particular direction over time and simply "drift," thanks in part to...more

Media and the Fertility Transition in Developing Countries (Guest Lecture by William Ryerson)
Yale / Biology
Guest lecturer William Ryerson is President of the Population Media Center which produces radio and TV serial dramas in developing countries that aim to effect behavior change on women's status, family planning and AIDS. Working with governments and in-country media professionals, these melodramas run for hundreds of episodes and are watched by millions. Careful research shows major changes in audience knowledge, attitudes and practices.
