Professor Wai Chee Dimock concludes her discussion of As I Lay Dying with an analysis of its generic form. Using Nathaniel Hawthorne’s The Scarlett Letter to anchor her discussion of the American literary tradition, she argues that As I Lay Dying continually negotiates the comic and the tragic genres as we shift from one perspective to another: one character’s comic gain is often another’s tragic loss.
Professor Wai Chee Dimock concludes her discussion of To Have and Have Not by showing how, in the context of the Cuban Revolutions and the Great Depression, characters devolve into those who “Have” and those who “Have Not.” While protagonist Harry Morgan may look like a political and economic “Have Not”–he neither supports the revolution nor possesses enough money to extract himself from its seedier operations–his ability to bring happiness to his wife Marie makes him a social “Have” in a more profound sense.
Professor Wai Chee Dimock traces Faulkner’s appropriation of the epic genre through two conventions: the blurring of boundaries between humans and non-humans and the resurrection of the dead. She first reads Faulkner’s minor character Tull and his relation to both mules and buzzards to draw out the “nature of manhood in poor whites.” From Tull, she shifts focus to Jewel and suggests that his kinship with the snake and the horse foregrounds the narrative secrecy of Jewel’s genealogy.
Professor Wai Chee Dimock begins her discussion of Faulkner’s As I Lay Dying by orienting the novel to the Great Depression in the South, as focalized through such famous texts as Let Us Now Praise Famous Men. Once this macro history is established, she reads the narrative techniques of As I Lay Dying through two analytic lenses. First, she draws on Bakhtin’s notion of social dialects to underscore the language that indexes poor whites as a Southern type.
Professor Wai Chee Dimock demonstrates how four of Fitzgerald’s most famous short stories–“The Rich Boy,” “Babylon Revisited,” “The Diamond as Big as the Ritz,” and “Bernice Bobs Her Hair”–represent “social types,” generic identities that Fitzgerald explores as forms of social reality. She reads the dramatic tension in each of those stories as determined by the protagaonist’s conformity to or deviation from their idealized social type.
Ice on earth is sensitive to climate change and ice plays a role in climate change processes. Recent trends in the Greenland ice sheet provide an important example. Over the past two decades the extent of surface melt water on the ice sheet has increased. In addition, satellites have detected a decrease in the overall mass of the Greenland Ice Sheet. Paleoclimate is also discussed in this lecture, with a focus on climate over the last 5 million years. The mid-Pliocene was a particularly warm period from 3.3-3 million years before present.
Five types of ice in the climate system are discussed. Sea ice forms when ocean water reaches its freezing temperature of about -2°C. Sea ice is currently found in the Arctic Ocean and around Antarctica. Ice sheets form on land and are composed of compacted snow that has accumulated over time. Ice sheets spread over a land surface and can reach the ocean. If the ice continuity is maintained when the ice sheet reaches the ocean, the ice will float on the water and this is referred to as an ice shelf. Icebergs are large chunks of glaciers that break off into the ocean.
The El Niño/Southern Oscillation (ENSO) phenomenon is the primary mode of variability in the equatorial Pacific Ocean. It is composed of two extreme states, El Niño and La Niña. The oscillation between these states can be seen in measurements of sea surface temperature (SST), sea level pressure, thermocline depth, and easterly trade wind strength. Changes in SST and pressure lead to shifting of convective activity across the equatorial Pacific.
Ocean currents are generally divided into two categories: thermohaline currents and wind driven currents. Both types of currents are forced remotely rather than locally. Wind driven currents are initially forced by the wind stress causing water to pile up in certain locations. This produces a pressure gradient, which is then balanced by the Coriolis force and geostrophic currents develop. The gyre circulations found in the Atlantic and Pacific Oceans are wind driven currents. There is a connection between the physics of these currents and the biological productivity in the ocean.
The atmosphere forces the ocean in three ways: addition and removal of heat, precipitation and evaporation, and wind stress. The former two processes influence the density of sea water. Gravity acts on these density differences to cause large-scale thermohaline currents Wind driven ocean currents are forced by the wind stress acting on the ocean surface which indirectly causes geostrophic currents.
