William James came of age at a time of great social and intellectual change in the United States. During this period, new professional identities proliferated, and a new culture of professionalization developed with important ramifications for conceptions of individual and social identity. Professionalization was also closely related to key intellectual...
Traditional interpretations of James Joyce's Dubliners have often focused on the pervasive "paralysis" of the city, covered in the stories' range of "childhood, adolescence, maturity, and public life." However, these approaches have limited their focus on the women in the stories, often spotlighting the male characters--and the author--through a Freudian...
Methane is a product of biogeochemical processes which respond to changes in climate. The history of atmospheric methane is recorded by ice cores providing insight into past changes in these biogeochemical processes. This dissertation is comprised of three studies which focus on centennial- and millenial-scale variability of methane from ice...
From the 1860s into the 1920s Edward Sylvester Morse (1838-1925) was a staunch advocate of Darwinian evolution and of science education in the U. S. and likewise for several years in Japan. He had a major impact on the American public’s understanding of evolution, both before and after he became...
The variable length, six-electrode plasma source for atomic
emission spectroscopy described here is operated from three
compact, simple, and inexpensive direct current power supplies. The
vertical arcs formed between the three electrode pairs completely
entrain the sample and are typically operated at 40 V and 20 A.
Three concentric quartz...
The public health and economic significance of rapid acid production
by lactic streptococci in controlled dairy fermentations is well
known. However, the fast acid-producing characteristic of these organisms
is not stable, and cultures of fast organisms have been shown
to contain slow cells. These studies were carried out to characterize...
Chemically defined liquid media were devised which supported
excellent growth of Taphrina cerasi and T. deformans. When grown
in fermentation culture vessels, T. cerasi and T. deformans released
cytokinins into the liquid media. The presence of these cell division
factors was demonstrated with the soybean tissue assay which is
specific...
The principal objective of this study was to identify
and investigate the underlying basis for variations in the
volumes of exports of U.S. winter pears during the 1947 to
1974 period. A number of factors thought to be of importance
in the determination of the volume of exports of a...
