Tracking the Trends in Inventory Management in the Automobile Manufacturing Industry Throughout the Business Cycle

This paper investigates the trends in inventory management in the automobile manufacturing industry during recessionary vs. non-recessionary periods. It is an empirical approach to testing the validity of the hypothesis that firms which carry leaner inventories perform better throughout the business cycle and are less affected by variability in the economy than less lean firms. The research also hopes to shed some light on how firm's financial statements can be manipulated through discretionary adjustments made by management pertaining to the valuation of inventories.

Shakespeare's Richard II and Henry V and Political Rebellions in the Reign of Queen Elizabeth I

The purpose of this thesis will be to examine how two acts of rebellion against Queen Elizabeth I influenced Shakespeare's writing of Richard II and Henry V, as well as the performance and publication of these plays. The treasonous plots and execution of Mary, Queen of Scots in the 1580s, as well as the failed Essex Rebellion of 1601, resulted in a sensitivity towards any writings that seemed to support a coup d'état. Shakespeare, being a well-informed and fairly well-connected playwright, wrote passages in the afore mentioned plays that clearly reflect the political turmoil of the times. Thus, his plays were censored both on stage and in print until after the death of Elizabeth in 1603.

Changes in miRNA Expression in a Model of Microcephaly

miRNAs function to regulate gene expression through post-transcriptional mechanisms to potentially regulate multiple aspects of physiology and development. Whole transcriptome analysis has been conducted on the citron kinase mutant rat, a mutant that shows decreases in brain growth and development. The resulting differences in RNA between mutant and wild-type controls can be used to identify genetic pathways that may be regulated differentially in normal compared to abnormal neurogenesis. The goal of this thesis was to verify, with quantitative reverse transcriptase polymerase chain reaction (qRT-PCR), changes in miRNA expression in Cit-k mutants and wild types. In addition to confirming miRNA expression changes, bio-informatics software TargetScan 5.1 was used to identify potential mRNA targets of the differentially expressed miRNAs. The miRNAs that were confirmed to change include: rno-miR-466c, mmu-miR-493, mmu-miR-297a, hsa-miR-765, and hsa-miR-1270. The TargetScan analysis revealed 347 potential targets which have known roles in development. A subset of these potential targets include genes involved in the Wnt signaling pathway which is known to be an important regulator of stem cell development.

The Effects of Heat Acclimation Followed by Sleep Deprivation on Perceived Exertion, Thirst, and Thermal Sensations in Exercising Males

Subjects were tested while walking on a tradmill for 11 days in a row at sub-maximal levels for 90 minutes the heat. After the 10th day, subjects were kept awake for 24 hours before being tested in a state of sleep deprivation on the 11th day. Subjects rated their perceived exertion, thirst levels, and thermal sensations at regular intervals before, during, and after exercise each day. The changes in RPE, thirst, and thermal sensations were examined to determine the progression of heat acclimation and to observe changes in the subjects' perceived workloads. While subjects were significantly less thirsty on day 10 than when beginning the study on day 1, no significant changes occured in regards to thermal sensations or RPE values. On the 11th day, these variables were again observed in order to examine the effects of sleep deprivation on the adaptations of heat acclimation. After 28 hours of sleep loss, subjects rated themselves as feeling significantly more thristy after exercise than they had on day 10, yet again there was no significant change in thermal sensations or RPE values. Throughout the study, RPE and thermal sensation ratings seemed to be closely linked while sensations of thirst fluctuated independently.

Conceptualizing Success in Therapeutic Wilderness Experiences: The Creation and Maintenance of Instructor-Participant Relationships

Researchers have noted that relationships created between instructors and clients in therapeutic wilderness experiences are unique (Russell, 2003; Russell & Phillips-Miller, 2001; Sklar, Anderson, & Autry, 2007; Taniguchi et al., 2009), but little research has been done to explore these relationships. The present study is an investigation of how instructors build and maintain relationships with participants, conceptualize these relationships, and define success in these tasks. Nine instructors from a wilderness program for at-risk youth participated in interviews. Data were analyzed using a line-by-line coding technique. Results of this study add to existing research on wilderness therapy and therapeutic wilderness experiences, provide models of successful instructing, and guide programs and instructors in the services they provide to their participants.

Alterations in the Cellular Composition of the Mouse Bladder Following Ovariectomy, Partial Bladder Outlet Obstruction, and Aging

Detrusor underactivity (DU) increases susceptibility to urinary retention and accordingly further complicates the management of urinary incontinence. Bladder muscle stretch, a lack of estrogen, and aging are 3 notable DU risk factors. The aim of this research is to better characterize the changes in cellular composition of the bladder that result from these 3 risk factors to gain a better understanding of DU pathogenesis and pathobiology. This research focuses on the effects of a lack of estrogen while also providing an outline for determining the effects of bladder muscle stretch and aging on the cellular composition of the bladder.

Game Theoretic Bidding Strategies for Auctions in Green Electricity Markets

Electricity markets in the United States presently employ an auction mechanism to determine the dispatch of power generation units. In this market design, generators submit bid prices to a regulation agency for review, and the regulator conducts an auction selection in such a way that satisfies electricity demand. Most regulators currently use an auction selection method that minimizes total offer costs ["bid cost minimization" (BCM)] to determine electric dispatch. However, recent literature has shown that this method may not minimize consumer payments, and it has been shown that an alternative selection method that directly minimizes total consumer payments ["payment cost minimization" (PCM)] may benefit social welfare in the long term. The objective of this project is to further investigate the long term benefit of PCM implementation and determine whether it can provide lower costs to consumers. The two auction selection methods are expressed as linear constraint programs and are implemented in an optimization software package. Methodology for game theoretic bidding simulation is developed using EMCAS, a real-time market simulator. Results of a 30-day simulation showed that PCM reduced energy costs for consumers by 12%. However, this result will be cross-checked in the future with two other methods of bid simulation as proposed in this paper.

Phonological Development in Hearing Children of Deaf Parents

Phonological development in hearing children of deaf parents Dr. Diane Lillo-Martin 5/9/2010 The researcher wishes to determine the significance of a unique linguistic environment on the effects of phonological development. The research examines whether 3 hearing children of deaf parents, hereafter referred to as CODAs, have inconsistencies, as compared to children in a typical linguistic environment, in their syllable structure, phonological processes or phonemic inventories. More specifically, the research asks whether their speech is more consistent with children of typical environments or more similar to children with phonological delays or disorders or articulation disorders. After the examination of these three components to a child's phonological development, it can be concluded that the linguistic environment of CODA children does not negatively hinder their phonological language development.

Text as Resistance in Holocaust Literature: Struggles for Personhood in Wiesel, Levi, and Delbo

This thesis is an examination of the memoirs of three core Holocaust writers, Elie Wiesel (Night and Day), Primo Levi (If This is A Man), and Charlotte Delbo (Auschwitz and After), exploring the ways in which each of the three authors uses his or her memoir to simultaneously document and resist the dehumanizing influence of the concentration camp experience.

The Impact of Thermal Coupling on Catalyst Behavior in Wall-Coated Heat-Exchanger Microreactors

This thesis presents a numerical study of reaction and diffusion phenomena in wall-coated heat-exchanger microreactors. Specifically, the interactions between an endothermic and exothermic catalyst layer separated by an impermeable wall is studied to understand the inherent behavior of the system. Two modeling approaches are presented, the first under the assumption of a constant thermal gradient and neglecting heat of reaction and the second considering both catalyst layers and reaction heat. Both studies found that thicker, more thermally insulating catalyst layers increase the effectiveness of the exothermic reaction by allowing for accumulation of reaction heat while thinner catalyst layers for the endothermic catalyst allow for direct access of the reactant to higher wall temperatures.

Alkylphenol Contamination in Homarus americanus

Alkylphenols are pollutants that are present in marine sediments and fishes. In earlier work it has been discovered that alkylphenols are present in the Homarus americanus, or the American lobster. Research suggests that alkylphenols could behave as endocrine disruptors as they have been found to affect juvenile hormone activity. It has been hypothesized that lobsters may be able to rid themselves of alkylphenol contamination through secreting these compounds into the environment or sequestering them in their tissues. In this study, I address the question of how lobsters may rid themselves of alkylphenols by analyzing hemolymph, muscle, gill, and shell samples and by looking for the presence of alkylphenols in natural and artificially injected lobsters. A total of thirty lobsters were analyzed. In my first study I found alkylphenols only in the gill tissue samples of natural lobsters after alkylphenols were initially found in the hemolymph, and found none in the muscle and shell samples. The types of alkylphenols found in the gills were often different than the alkylphenols found in the hemolymph. The gills are known as a site for exchange for the lobster. The lobster may not only be excreting alkylphenols from its gill surfaces but these findings suggest that the lobster may also be acquiring alkylphenols in the environment from these surfaces. It is possible that the lobsters may have ingested additional contaminants after the hemolymph samples were taken and before the gill samples were taken. As for the shell and muscle samples, it is possible that by our method the levels were too low to detect since we have a threshold of detection of 1ng/mL. It is also a conclusion that alkylphenols were not sequestered in these tissues. In the second study, an expanded set of muscles samples from natural lobsters were tested as well as additional lobsters that were artificially injected with one of our alkylphenol compounds of interest, compound three. We found that lobsters injected with peak three showed significantly higher alkylphenol concentrations in all tissues, most notably the gill samples. The non-injected lobsters that died shortly after being in the laboratory, showed mostly peak three but their overall values were much less than those of the injected lobsters.

Requirements for Staphylococcus aureus in vitro cellular internalization

Staphylcoccus aureus is a prokaryotic organism capable of causing numerous superficial and severe human infections. Adhesion of S. aureus to host tissues or cells is believed to be a crucial event in S. aureus infections. Subsequently, S. aureus can seed into the bloodstream resulting in metastasis of the infection. Several reports show that S. aureus can be internalized by non-professional phagocytes, a process which has been proposed to be important in S. aureus dissemination. An intracellular residence has also been proposed to provide safe harbor to reservoirs of dormant bacteria contributing to the persistence of infection. This dissertation describes an investigation into the molecular mechanisms of S. aureus internalization into both fibroblast and epithelial cells. Bacterial requirements for internalization were found to be limited to expression of proteins that bind the extracellular matrix protein fibronectin. A previously unknown fibronectin-binding region in the S. aureus fibronectin-binding protein A was discovered after showing competitive inhibition of S. aureus internalization. This novel fibronectin-binding activity is characterized. Internalization also required cell-based factors. The presence of fibronectin and cell surface receptors of the β1 integrin class, which are known to bind and internalize fibronectin, were found to be necessary for optimal internalization of S. aureus. These results led to the conclusion that fibronectin acts as a bridge between the bacterium and integrins on the host cells. The internalization process exhibits features characteristic of integrin-mediated cell migration on fibronectin-coated surfaces. Both processes involved an active form of the β1 integrin subunit and the protein tyrosine kinase Src. Finally, a Src inhibitor previously shown to be effective in reducing osteoporosis in an in vivo rat model is capable of greatly reducing S. aureus internalization. ^

Ionotropic Glutamate Receptors Show Unique Distribution and Localization in the Dorsal Cochlear Nucleus of the Rhesus Monkey

The dorsal cochlear nucleus (DCN) receives auditory information via the auditory nerve coming from the cochlea. It is responsible for much of the integration of auditory information, and it projects this auditory information to higher auditory brain centers for further processing. This study focuses on the DCN of adult Rhesus monkeys to characterize two specific cell types, the fusiform and cartwheel cell, based on morphometric parameters and type of glutamate receptor they express. The fusiform cell is the main projection neuron, while the cartwheel cell is the main inhibitory interneuron. Expression of AMPA glutamate receptor subunits is localized to certain cell types. The activity of the CN depends on the AMPA receptor subunit composition and expression. Immunocytochemistry, using specific antibodies for AMPA glutamate receptor subunits GluR1, GluR2/3 and GluR4, was used in conjunction with morphometry to determine the location, morphological characteristics and expression of AMPA receptor subunits in fusiform and cartwheel cells in the primate DCN. Qualitative as well as quantitative data indicates that there are important morphological differences in cell location and expression of AMPA glutamate receptor subunits between the rodent DCN and that of primates. GluR2/3 is widely expressed in the primate DCN. GluR1 is also widely expressed in the primate DCN. GluR4 is diffusely expressed. Expression of GluR2/3 and GluR4 in the primate is similar to that of the rodent. However, expression of GluR1 is different. GluR1 is only expressed by cartwheel cells in the rodent DCN, but is expressed by a variety of cells, including fusiform cells, in the DCN of the primate.
