Show moreA contemporary debate by Morgeson, Campion, Dipboye, Hollenbeck, Murphy, and Schmitt (2007) highlighted the fact that personality validity when predicting job performance has not changed since the influential review of Guion and Gottier (1965), who originally determined that utilizing personality validites were too modest to be useful as a personnel selection tool. The goal of this thesis was to test several propositions regarding the low validity of personality to predict job performance. The three issues proposed herein all focus on different aspects of the personality validation issue, and although all three are inter-related they also uniquely focus on a different aspect of the validation methodology that is used in modern psychology. Two of the issues also utilize general mental ability as a comparative tool, due to general mental ability’s continual use as a predictive tool. The first issue addressed whether personality, as defined narrowly as conscientiousness, exhibited a nonlinear relationship with job performance after controlling for general mental ability. The second issue hypothesized that the length of the latent construct in comparison to the latent construct of general mental ability might simply be a shorter metric and this was tested using a three-part criterion taxonomy that was developed for this study. The third issue asked if the creation of personality scales using ideal-point methods instead of the more typical classical construction method would result in higher criterion related validity. The results generally found linearity between the personality – job performance relationship. The personality scale also separated between the tail ends of the criteria better than the measure of general mental ability. The newly constructed alternative scales, on average, ix did not outpeform the classically constructed measure of personality, although in a few instances the alternatives did better.

Title: ELECTROCHEMICAL, TRANSPORT AND THERMAL INVESTIGATION OF NOVEL ELECTROLYTES AND ELECTRODES FOR LITHIUM-ION AND MAGNESIUM-ION BATTERIES

Show moreEnergy conversion and energy storage are becoming indispensable in today’s society due to the increased demand for immobile and mobile power. Cathode material is considered as the only source of energy in the electrochemical cell for secondary battery and thus the quantity of energy of the battery is largely determined by the type of the cathode’s chemistry and its amount used as well. Electrolyte has also a significant impact on the electrochemical performance of the battery. Its properties such as ionic conductivity and transference number play a substantial role in the transport of energy between the cathode and the anode. Moreover, the electrolyte can also limit the accessibility of the active charged ions into the active material through the formation of a Solid Electrolyte Interface (SEI). In addition to the importance of energy, safety is another critical element in the determination of the battery’s quality. Cathode material and non-aqueous electrolyte are two major dimensions of the safety in the design of secondary battery. For instance, in the presence of heat (due to thermal, mechanical, or electrical abuse), the electrolyte can ignite fire if the cathode material releases the oxygen. Therefore, the cathode materials and electrolytes are both central factors in the determination of battery energy and safety. Nowadays, lithium-ion batteries are widely used as power source in many applications; however, their maximum energy density (400Wh/Kg) is not sufficient enough to meet the demands of high power applications such as electric vehicles owing to the limited driving range caused by current lithium-ion batteries. Furthermore, safety concerns have been raised after several incidents have been reported recently. Therefore, improving the safety of lithium-ion battery systems through the formulation of non-flammable electrolytes and synthesizing stable electrodes are highly required for high thermal stability. In contrast, fulfilling the long driving range requires other battery systems that provide higher energy density. The large energy density of Mg metal (3832 mAh/cm3) opens a new horizon toward future potential energy storage system, which is a very promising candidate to overcome the long driving range issue and thus needs to be investigated for its potential use as rechargeable battery. In this present thesis, thermal stability of lithium-ion cells is examined through the use of Fluoro Ethylene Carbonate (FEC) as non-flammable co-solvent with Ethylene Carbonate (EC) on lithium-nickel-cobalt-aluminum-oxide cathode (LiNi0.8Co0.15Al0.05O2). This cathode chemistry was deliberately chosen because of its low thermal stability due to the oxidation of Ni+3 to Ni+4 upon charging. Additionally, optimization of the cathode composition (active material, conducting agent, binder) was examined for high energy and power. Lithium iron phosphate (LiFePO4) was chosen for this study because of its high thermal stability against the liberation of oxygen. Electrolytic properties of a magnesium organohaloaluminate electrolyte were investigated in order to understand their role and effect on the magnesium deposition process. Electrochemical and thermal study of bismuth material as a potential negative electrode for magnesium-ion cell under the use of magnesium organohaloaluminate electrolyte was also performed. Moreover, a thermal modeling was performed through the use of Isothermal-Micro-Calorimeter (IMC) technique to identify the sources of heat released during the magnesiation and demagnesiation of bismuth electrode.

Show moreOperation Iraqi Freedom (OIF) and Operation Enduring Freedom (OEF) veterans are acquiring disabilities during deployment with the two most common disabilities being Post Traumatic Stress Disorder (PTSD) and Traumatic Brain Injury (TBI). Past research has shown that persons with disabilities are stigmatized and often held personally responsible for their disabilities. The present study utilized Bernard Weiner’s theory of attribution to investigate whether (1) type of disability, (2) disability context, (3) level of familiarity, or (4) political ideology influences whether or not the returning OIF/OEF veterans with disabilities population are blamed for their disabilities. One hundred and seventy-seven undergraduate students read a short vignette of a veteran who sustained a disability, and completed measures of stigmatizing attributions, political ideology, and familiarity with persons with disabilities. Results showed a significant relationship to disability context and stigmatizing attributions of blame. Specifically, veterans who sustained their injuries as a result of not following their commander’s orders were seen as more personally responsible for their disability than veterans who sustained their injuries while following their commander’s orders. No significant relationships between disability type, political ideology, or level of familiarity were found. Recommendations for reducing stigmatizing societal barriers when veterans with disabilities reintegrate back into civilian life and future research studies are discussed.
