Purification And Crystallization Of A Non-Glur2 Ampa-Receptor Ligand-Binding Domain: A Case Of Cryo-Incompatibility Addressed By Room-Temperature Data Collection, Avinash Gill, Dean R. Madden

Dartmouth Scholarship

Glutamate is the major excitatory neurotransmitter in the brain. Among the cognate ionotropic glutamate receptors, the subfamily selective for AMPA (alpha-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid) is responsible for most fast excitatory synaptic signaling and plays key roles in synaptic plasticity. AMPA receptors (AMPA-Rs) have also been implicated in a number of neurological disorders. To investigate subunit-specific differences in the ligand binding and activation of AMPA-Rs, the GluR4 AMPA-R ligand-binding domain (LBD) was crystallized in complex with full and partial agonists. This is the first non-GluR2 AMPA-R LBD available for structural analysis. Standard cryoprotection protocols yielded high-resolution diffraction from flash-cooled crystals of the …

Labor Market Segregation And The Wage Differential Between Resident And Migrant Workers In China, Ruosi Lu

Lingnan Theses

This thesis looks at the effect of industrial and occupational segregation on the wage differential between resident and migrant workers in China. It extends the work of Meng and Zhang (2001) by considering the possible employment segregation of resident and migrant workers by both industry and occupation. I contend that industry segregation is at least as important as occupational segregation for Chinese migrant workers, as most migrant workers in China have come from the countryside to fuel the booming labor-intensive manufacturing and construction industries in the cites. Due to the hukou policy (a household registration system) in China, migrant workers …

The existence and increasing influence of global consumers whose …

Technological Disasters: An Investigation Of The Conservation Of Resources Theory On Depression, Brian Gentry

Electronic Theses and Dissertations

Researchers studying the affects of resource loss following a technological disaster have exclusively investigated the acute period directly after the event occurred. This study applied Hobfoll's (1988, 1989) Conservation of Resources model in order to examine the long term effects of resource loss on depression in Cordova, Alaska a decade after the Exxon Valdez Oil spill. Results suggest that resource loss was a more prominent predictor for depression than demographics, involvement in the on-going litigation, or commercial fishing jobs. The research concludes that certain aspects of resource loss are critical in the development of depression after a technological disaster, and …

The Endocytic Protein Numb Regulates App Metabolism And Notch Signaling: Implications For Alzheimer's Disease, George Kyriazis

Electronic Theses and Dissertations

Increased production of amyloid beta (A-beta) peptide, via altered proteolytic cleavage of amyloid protein precursor (APP), and abnormalities in neuronal calcium homeostasis play central roles in the pathogenesis of Alzheimer's disease (AD). Notch1, a membrane receptor that controls cell fate decisions during development of the nervous system, has been linked to AD because it is a substrate for the gamma-secretase protein complex in which mutations cause early-onset inherited AD. Numb is an evolutionarily conserved endocytic adapter involved in the internalization of transmembrane receptors. Mammals produce four Numb isoforms that differ in two functional domains, a phosphotyrosine-binding domain (PTB) and a …

Brothers & Sisters: A New Impetus For Social Construction And Its Impact On Traditional Cultivation Analysis, Scott Elmore

Integrating Key Elements In An E-Learning Curriculum For An Optimum Educational And Interactive User Experience, Heather Stearns

Electronic Theses and Dissertations

This study determines the particular components that are considered the best practices to use when implementing an e-Learning curriculum. Technical communicators and instructional designers have numerous development options to choose from. However, practices that work in academe do not always integrate well in a corporate setting, and what works for one corporation may not work for another. There is no singular methodology for developers to apply that enables e-Learning to fit every organization's needs. Research shows that to ensure a successful online learning implementation, a sound project management team must be in place at the beginning of the project planning. …

Beyond Postmodern Margins: Theorizing Postfeminist Consequences Through Popular Female Representation, Victoria Mosher

Electronic Theses and Dissertations

In 1988, Linda Nicholson and Nancy Fraser published an article entitled "Social Criticism Without Philosophy: An Encounter Between Feminism and Postmodernism," arguing that this essay would provide a jumping point for discussion between feminisms and postmodernisms within academia. Within this essay, Nicholson and Fraser largely disavow a number of second wave feminist theories due to their essentialist and foundationalist underpinnings in favor of a set of postmodernist frameworks that might help feminist theorists overcome these epistemological impediments. A "postmodern feminism," Nicholson and Fraser claim, would become "the theoretical counterpart of a broader, richer, more complex, and multilayered solidarity, the sort …

Trait Arousability And Its Impact On Adaptive Multimedia Training, Sae Schatz

Electronic Theses and Dissertations

Today's best intelligent, adaptive, multimedia trainers have shown excellent performance; however, their results still fall far-short of what good human tutors can achieve. The overarching thesis of this paper is that future intelligent, adaptive systems will be improved by taking into account relevant, consistent, and meaningful individual differences. Specifically, responding to individual differences among trainees will (a) form more accurate individual baselines within a training system, and (b) better inform system responses (so that they interpret and respond to observable data more appropriately). One variable to consider is trait arousability, which describes individual differences in sensitivity to stimuli. Individuals' arousability …
