The Indian Removal Debate and the Rise of Partisan Identity In the Age of Jackson

The election of Andrew Jackson to the presidency in 1828 coincided with the rise of the nation\u27s second party system. The divide which emerged between Jacksonian Democrats and their opposition party, the Whigs, is generally accepted as marking the origin of an American political culture defined by a partisan divide. Political historians of the period have often focused on the key divisive issues: South Carolina\u27s nullification agitation, the Bank Crisis, and working class identity politics have been most often featured in this scholarship. The Indian Removal Debate has generally been examined as ancillary to these partisan developments, an after-effect for all intents and purposes. This study places the Indian Removal Debate at the center of the emerging partisan rift, and argues that the debate actually helped craft the partisan identities that would inform both sides. In particular, Jacksonian Democrats pursued a dialogue of racial constmction regarding Indians, and the resulting constmct served to fortify their identity claims as the party of practicality. The results of the Indian Removal De bate reached far beyond the Indian issue, as Democrats carried the identity forged in that debate into other arenas as well. The study is based on the records of the United States Congress for the relevant period, and also includes examinations of personal and professional writings created by William Gilmore Simms, and by former Georgia governors and engaged Indian Removal activists George Gilmer and Wilson Lumpkin

Half in Shadow

Nellie Y. McKay (1930–2006) was a pivotal figure in contemporary American letters. The author of several books, McKay is best known for coediting the canon-making with Henry Louis Gates Jr., which helped secure a place for the scholarly study of Black writing that had been ignored by white academia. However, there is more to McKay's life and legacy than her literary scholarship. After her passing, new details about McKay's life emerged, surprising everyone who knew her. Why did McKay choose to hide so many details of her past? Shanna Greene Benjamin examines McKay's path through the professoriate to learn about the strategies, sacrifices, and successes of contemporary Black women in the American academy. Benjamin shows that McKay's secrecy was a necessary tactic that a Black, working-class woman had to employ to succeed in the white-dominated space of the American English department. Using extensive archives and personal correspondence, Benjamin brings together McKay’s private life and public work to expand how we think about Black literary history and the place of Black women in American culture

Singlet oxygen-mediated photochemical cross-linking of an engineered fluorescent flavoprotein iLOV

Genetically encoded photoactive proteins are integral tools in modern biochemical and molecular biological research. Within this tool box, truncated variants of the phototropin two light-oxygen-voltage flavoprotein have been developed to photochemically generate singlet oxygen (1O2) in vitro and in vivo, yet the effect of 1O2 on these genetically encoded photosensitizers remains underexplored. In this study, we demonstrate that the "improved" light-oxygen-voltage flavoprotein is capable of photochemical 1O2 generation. Once generated, 1O2 induces protein oligomerization via covalent cross-linking. The molecular targets of protein oligomerization by cross-linking are not endogenous tryptophans or tyrosines, but rather primarily histidines. Substitution of surface-exposed histidines for serine or glycine residues effectively eliminates protein cross-linking. When used in biochemical applications, such protein-protein cross-links may interfere with native biological responses to 1O2, which can be ameliorated by substitution of the surface exposed histidines of improved" light-oxygen-voltage or other 1O2-generating flavoproteins

The Effect of Varying Sound Intensities on Phonotactic Selectivity in Female Acheta domesticus

Female cricket Acheta domesticus recognize and respond to the call of the conspecific male by walking towards it (phonotaxis). Such phonotactic response has been described as selective, e. g. females are more likely to respond phonotactically to calls with syllable periods typical of the males’ calling song than they are to respond to calls with unattractive syllable periods (Stout et al., 1983). A previous study by Popov and Shuvalov (1977) concluded that phonotaxis can be altered by internal and external conditions. One internal condition that can modify selective phonotaxis is age (Henley et al. 1992; Stout et al. 2010). Here we demonstrate that sound intensity is an external condition that can also modify selective phonotaxis. The recognition of the call of the male by the female has become an important model to evaluate the nervous system processing that underlies the encoding and recognition of signals which communicate information regarding the behavioral state of the sender

Advanced Compatibility Characterization Of AF-M315E With Spacecraft Propulsion System Materials Project

All spacecraft require propulsion systems for thrust and maneuvering. Propulsion systems can be chemical, nuclear, electrical, cold gas or combinations thereof. Chemical propulsion has proven to be the most reliable technology since the deployment of launch vehicles. Performance, storability, and handling are three important aspects of liquid chemical propulsion. Bipropellant systems require a fuel and an oxidizer for propulsion, but monopropellants only require a fuel and a catalyst for propulsion and are therefore simpler and lighter. Hydrazine is the state of the art propellant for monopropellant systems, but has drawbacks because it is highly hazardous to human health, which requires extensive care in handling, complex ground ops due to safety and environmental considerations, and lengthy turnaround times for reusable spacecraft. All users of hydrazine monopropellant must contend with these issues and their associated costs. The development of a new monopropellant, intended to replace hydrazine, has been in progress for years. This project will apply advanced techniques to characterize the engineering properties of materials used in AF-M315E propulsion systems after propellant exposure. AF-M315E monopropellant has been selected HQ's Green Propellant Infusion Mission (GPIM) to replace toxic hydrazine for improved performance and reduce safety and health issues that will shorten reusable spacecraft turn-around time. In addition, this project will fundamentally strengthen JSC's core competency to evaluate, use and infuse liquid propellant systems

Primary Relaxation Processes at the Band Edge of SiO₂

The kinetics of photoinduced defect formation in high-purity silicas has been studied by femtosecond transient absorption spectroscopy in the visible and ultraviolet. Band edge two-photon excitation produces singlet excitons which decay in 0.25 ps into defects with the absorption spectra of nonbridging oxygen hole centers (≡Si-O⋅) and silicon E’ centers (≡Si⋅). We identify these defect pairs with the self-trapped triplet exciton and the 0.25 ps decay with the motion of the photoexcited oxygen atom. Similar results were obtained with both crystalline and amorphous silica samples

Precious-Metal Salt Coatings for Detecting Hydrazines

Substrates coated with a precious-metal salt KAuCl4 have been found to be useful for detecting hydrazine vapors in air at and above a concentration of the order of 0.01 parts per million (ppm). Upon exposure to air containing a sufficient amount of hydrazine for a sufficient time, the coating material undergoes a visible change in color

Historical Evolution of NASA Standard Materials Testing with Hypergolic Propellants and Ammonia (NASA Standard 6001 Test 15)

The NASA Johnson Space Center White Sands Test Facility (WSTF) has performed testing of hazardous and reactive aerospace fluids, including hypergolic propellants, with materials since the 1960s with the Apollo program. Amongst other test activities, Test 15 is a NASA standard test for evaluating the reactivity of materials with selected aerospace fluids, in particular hydrazine, monomethylhydrazine, uns-dimethylhydrazine, Aerozine 50, dinitrogen tetroxide oxidizers, and ammonia. This manuscript provides an overview of the history of Test 15 over a timeline ranging from prior to its development and first implementation as a NASA standard test in 1974 to its current refinement. Precursor documents to NASA standard tests, as they are currently known, are reviewed. A related supplementary test, international standardization, and enhancements to Test 15 are also discussed. Because WSTF was instrumental in the development and implementation of Test 15, WSTF experience and practices are referred to in this manuscript
