"She Was Not Even Normal": Unreliable Narratives of Female Insanity in Jane Eyre, Rebecca, and Wide Sargasso Sea

In my thesis, I interrogate narrative reliability related to depictions of female insanity in Jane Eyre, Rebecca, and Wide Sargasso Sea. By subjecting the trustworthiness of her storytelling to criticism, especially as regards the concealed madwoman, Bertha Mason, Jane's narration is revealed as unstable, offering problematic insight into a character long considered unflinchingly honest. In du Maurier's later literary adaptation of Jane Eyre, Bertha's parallel character, the eponymous Rebecca, comes to the fore, while the novel's unnamed narrator remains in the shadows, and bases much of her storytelling upon hearsay, rather than the "autobiography" of Jane Eyre. The most transparent narrative voice, however, is Antoinette, the main character of Wide Sargasso Sea, the 1966 prequel to Jane Eyre. Despite her madness, Antoinette's narration makes no attempt at dissemblance, speaking forthrightly about her marriage and experience, proving a truthful narrator and openly rejecting the marginal status the earlier narrators try desperately to hide.

Ortho Effect in the Bergman Cyclization: Electronic and Steric Effects in Hydrogen Abstraction by 1-Substituted Naphthalene 5,8-Diradicals

We present a detailed theoretical study of geometries, electronic structure, and energies of transition states and intermediates completing the full Bergman cycloaromatization pathway of ortho-substituted enediynes with a focus on polar and steric contributions to the kinetics and thermodynamics of hydrogen abstraction. This study provides a rare unambiguous example of remote substitution that affects reactivity of a neutral reactive intermediate through an σ framework.

Age, Sex, and Telomere Dynamics in a Long-Lived Seabird with Male-Biased Parental Care

The examination of telomere dynamics is a recent technique in ecology for assessing physiological state and age-related traits from individuals of unknown age. Telomeres shorten with age in most species and are expected to reflect physiological state, reproductive investment, and chronological age. Loss of telomere length is used as an indicator of biological aging, as this detrimental deterioration is associated with lowered survival. Lifespan dimorphism and more rapid senescence in the larger, shorter-lived sex are predicted in species with sexual size dimorphism, however, little is known about the effects of behavioral dimorphism on senescence and life history traits in species with sexual monomorphism. Here we compare telomere dynamics of thick-billed murres (Uria lomvia), a species with male-biased parental care, in two ways: 1) cross-sectionally in birds of known-age (0-28 years) from one colony and 2) longitudinally in birds from four colonies. Telomere dynamics are compared using three measures: the telomere restriction fragment (TRF), a lower window of TRF (TOE), and qPCR. All showed age-related shortening of telomeres, but the TRF measure also indicated that adult female murres have shorter telomere length than adult males, consistent with sex-specific patterns of ageing. Adult males had longer telomeres than adult females on all colonies examined, but chick telomere length did not differ by sex. Additionally, inter-annual telomere changes may be related to environmental conditions; birds from a potentially low quality colony lost telomeres, while those at more hospitable colonies maintained telomere length. We conclude that sex-specific patterns of telomere loss exist in the sexually monomorphic thick-billed murre but are likely to occur between fledging and recruitment. Longer telomeres in males may be related to their homogamous sex chromosomes (ZZ) or to selection for longer life in the care-giving sex. Environmental conditions appeared to be the primary drivers of annual changes in adult birds.

Runoff Water Quality and Pollutant Mass Loads From Extensive Green Roofs

Green roof mitigation of volume and peak flow-rate of stormwater runoff has been studied extensively. However, due to the common practice of green roof fertilization, there is the potential for introduction of nutrients into local bodies of water. Therefore, this study compares green roof runoff quality with the water quality of precipitation and runoff from a bare shingle roof. The runoff from a demonstration-scale extensive green roof was analyzed during the summer of 2011 for its effect on runoff volume and analyzed during eleven storm events in the fall and winter for concentrations of copper, cadmium, zinc, lead, nitrogen species, total nitrogen, total organic carbon, sulfate, orthophosphate, and other monovalent and divalent ions. The green roof reduced the overall volume of runoff and served as a sink for NO3 - and NH4 +. However, the green roof was also a source for the pollutants PO4 3-, SO4 2-, TOC, cations, and total nitrogen. Metals such as zinc and lead showed trends of higher mass loads in the bare roof runoff than in precipitation and green roof runoff, although results were not statistically significant. The green roof also showed trends, although also not statistically significant, of retaining cadmium and copper. With the green roof serving as a source of phosphorous species and a sink for nitrogen species, and appearing to a retain metals and total volume, the life cycle impact analysis shows minimum impacts from the green roof, when compared with precipitation and bare roof runoff, in all but fresh water eutrophication. Therefore, the best environments to install a green roof may be in coastal environments.

Crosslinking Studies To Probe Substrate Binding By Soybean Lipoxygenase-1

Soybean lipoxygenase-1 (SBLO-1) catalyzes the oxygenation of polyunsaturated fatty acids into conjugated diene hydroperoxides. The three dimensional structure of SBLO-1 is known, but it is not certain how substrates bind. One hypothesis involves the transient separation of helix-2 and helix-11 located on the exterior of the molecule in front of the active site iron. A second hypothesis involves a conformational change in the side chains of residues leucine 541 and threonine 259. To test these hypotheses, site directed mutagenesis was used to create a cysteine mutation on each helix, which could allow for the formation of a disulfide linkage. Disulfide formation between the two cysteines in the T259C,S545C mutant was found to be unfavorable, but later shown to be present at higher pH values using SDS-PAGE. Treatment of the T259C,S545C with the crosslinker 2,3-dibromomaleimide (DBM) resulted in a 50% reduction in catalytic activity. No loss of activity was observed when the single mutant, S545C, or the wild type was treated with DBM. Single mutants T259C and L541C both showed approximately 20% reduction in the rate after addition of DBM. Double mutants T259C,L541C and S263C,S545C showed approximately 30% reduction in the rate after addition of DBM. Single mutants T259C and L541C showed an increase in activity after incubation with NEM. Double mutants T259C,S545C and T259C,L541C showed an increase in activity after incubation with NEM. The S263C,S545C double mutant showed a slight decrease in activity in the presence of NEM. It is unclear how the NEM and DBM are interacting with the molecule, but this can easily be determined through mass spectrometry experiments.

Distress Disclosure and Personality in College Students

This study examined distress disclosure, the tendency to confide unpleasant feelings and experiences to others. Other factors under consideration were gender, personality factors (such as extraversion and one's general tendency to disclose), and the identity of the person to whom individuals were asked to disclose. The subject pool included 22 male and 34 female volunteers from Bucknell University. Participants were asked to complete a measure of basic demographics, the Distress Disclosure Index, and the NEO-FFI measure of personality. They were then asked to disclose about an aspect of their lives that they personally found stressful, as if they were confiding in a best friend, a parent, or a professor, respectively. The transcriptions of those recordings were coded for length, depth, and breadth of the disclosure. The researcher hypothesized that greater length, depth, and breadth would be disclosed by females who scored highly on the Distress Disclosure Index, had high extraversion scores on the NEO-FFI, and had been asked to disclose to a best friend. The study found positive associations between openness and depth, neuroticism and depth, and gender with length, such that males were more likely to have longer disclosures. Negative associations were found between extraversion and depth, neuroticism and length, and openness and breadth. Personality factors, gender, and the disclosure target may act as better predictors of the tendency to disclose, rather than of the particular dimensions of disclosure, since every instance is unique.

Spirocyclic Acylphloroglucinol Derivatives from Hypericum pyramidatum

Five spirocyclic acylphloroglucinol derivatives (1-5) have been isolated from a hexanes extract of the leaves of Hypericum pyramidatum. Pyramidatones A-D (1-3, 5) are new, and chipericumin C (4) has been previously reported. The acylphloroglucinols were characterized based on spectroscopic (NMR, IR, UV-VIS) and mass spectrometric data.
