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

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

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

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

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

Short Terahertz Pulses from Semiconductor Surfaces: The Importance of Bulk Difference‐Frequency Mixing

The crystallographic orientation dependence of the far‐infrared (FIR) light generated at the (001) surface of a zincblende semiconductor is shown to derive principally from bulk difference‐frequency mixing. A strong modulation is observed for 1‐GW/cm2 pulses on InP, which demonstrates that the radiated FIR wave produced by bulk optical rectification is comparable to that generated by the transport of photoinjected carriers. Using the bulk rectification light as a clock, we show that more than 95% of the light produced from an InP (111) crystal by 100‐fs, 100‐μJ pulses is generated in a time shorter than the excitation pulse

Fostering Socio-Ecological Resilience to Wildfire by Interconnecting Knowledge Systems at Cal Poly Humboldt

The wildfire-related challenges of Northern California and many other regions in the western United States are daunting in scope and magnitude. Ecologically and culturally salient solutions that limit the negative impacts of wildfire and promote resilience of human and ecological systems will require newer approaches. Through Cal Poly Humboldt and the Fire Resilience Institute, there is greater emphasis on the interconnection of knowledge systems across education, training, research, and management. Here we highlight several on-going efforts that seek to enhance the fire resilience workforce, promote socio-ecological resilience through interdisciplinary projects, and inform management through monitoring and research projects that intentionally incorporate multiple knowledge systems. Shifting to a more inclusive process has many potential benefits but will also pose challenges and require modification of approaches. Here we emphasize some on-going efforts at Cal Poly Humboldt to intentionally bridge knowledge systems to make advances on wildfire-related challenges. Socio-ecological resilience and coexistence with fire can be fostered but the long-term effectiveness will greatly benefit from approaches that are inclusive, equitable, and interconnected across the many stakeholders affected and disciplines involved
