Review of Nineteenth-Century Geographies: The Transformation of Space from the Victorian Age to the American Century, eds. H. Michie and R. Thomas

It is by now a banal observation that published collections of conference papers tend to add up to a whole that is considerably less than the sum of the parts. Nineteenth-Century Geographies, a book that grew out of an interdisciplinary conference held at Rice University in 1998 falls into this category. While assuring my readers that each individual contribution is independently worth a read is likewise a predictable cliché, it is in fact the case that every one of the 17 articles collected here—notwithstanding the rather convoluted Introduction—has much to offer the study, broadly speaking, of ‘cultural spaces’ of British and American imperialisms in the nineteenth century. . . . All of my complaints aside, this turns out to be a much more enjoyable book to read than to review, and I would recommend skimming and dipping at length. I cannot quite imagine when a read-through of this book might be called for, except perhaps in graduate seminars on related topics.

Faith and the Sublation of Modernity: Kierkegaard and the Transformation of Fideism

This article retraces the “genealogy” of the fideist perspective in philosophy as well as literature, especially within the writings of Søren Kierkegaard and the novel Don Quixote. It contends that a demythologized perspective of the fideist-humanist sort, based upon Erasmian tolerance and intellectual creativity and updated with the insights of post-analytic theory (e.g., the work of Alasdair MacIntyre, Richard Rorty, and Jeffrey Stout), without revoking the vocabulary of transcendence, can reinforce the weathered but still valuable post-Enlightenment moral vocabulary, and can reiterate the humaneness of liberal hope without undue encumbrance from the dogmatic baggage of traditional theological jargon and metaphysics.

Understanding Bile Micelle Chiral Interactions

Bile salts are known to aggregate into micelles in biological systems; however, the fundamental structure and dynamics of bile molecule micelle formation are poorly understood. Previous studies have established that the bile salt cholate is capable of performing chirally selective micellar electrokinetic capillary chromatography (MEKC) separations of model racemic binaphthyl compounds 1,1¿-binaphthyl-2,2¿-diyl hydrogen phosphate (R,S-BNDHP) and 1,1¿-bi-2-naphthol (R,S-BN). Nuclear magnetic resonance (NMR) has been established as a complementary technique for understanding chiral selectivity and micelle formation events based on changes in proton chemical shifts of the probe molecules BNDHP and BN as well as of cholate. This work investigated the effects of the probe molecule, the alkali cation identity and temperature on cholate micelle aggregation and MEKC separations of R,S-BN and R,S-BNDHP. The probe molecule was found to mediate micelle formation by MEKC and proton NMR. A low (0.1 mM) concentration of probe was found to have minimal effects on micellization events detected by proton NMR while higher probe concentration (2.5 mM) was found to mediate micellization causing micellization events to occur at lower cholate concentrations. This work also investigated the effects of alkali counterion on chiral separation. Generally, counterions with larger crystal cationic radius were found to cause greater chiral separation power. NMR data suggest that protons near the surface of the cholate micelle are most sensitive to the cation identity, suggesting a model of improved separation based on the cation sterically inhibiting binding of one isomer. Finally, the effect of temperature on MEKC separation was investigated. Separation power of R,S-BN and R,S-BNDHP appeared to increase linearly with temperature for 22.0 mM to 50.0 mM pH 12.0 cholate. In total, these results indicate that cholate aggregation is dependent on multiple conditions. Understanding the roles that these factors play in influencing cholate micellization can inform better separation in MEKC.
