Predicting long term job performance using a cognitive ability test.

Description: This study focuses on the relationship of one cognitive ability test on long-term job performance as measured by personnel data. Archival data from over 3,000 employees at an international technology company were used to assess how aptitude test scores relate to both objective and subjective job performance measures. Supervisory performance ratings, level of promotion, and salary increase significantly contributed to variance in test scores; however, these results were inconsistent. Number of t… more

Study of Substituted Benzenesulfonate-Containing Layered Double Hydroxides and Investigation of the Hexamethylenetetramine Route of LDH Synthesis

Description: Benzenesulfonates, para-substituted with amine, chloride and methyl groups were successfully incorporated into layered double hydroxides of two different compositions, 2:1 Mg-Al LDH and 2:1 Zn-Al LDH. These parent materials were also doped with small amounts of nickel and the differences in the two systems were studied. The hexamethylenetetramine route of layered double hydroxide synthesis was investigated to verify if the mechanism is indeed homogeneous. This included attempting preparation of… more

Studying Interactions of Gas Molecules with Nanomaterials Loaded in a Microwave Resonant Cavity

Description: A resonant cavity operating in TE011 mode was used to study the adsorption response of single walled carbon nanotubes (SWCNTs) and other nanomaterials for different types of gas molecules. The range of the frequency signal as a probe was chosen as geometry dependent range between 9.1 -9.8 GHz. A highly specific range can be studied for further experiments dependent on the type of molecule being investigated. It was found that for different pressures of gases and for different types of nanomater… more

An examination of the effects of accuracy+rate versus accuracy+observing response training methods on matching-to-sample performance.

Description: The relative efficacy of training procedures emphasizing accuracy versus those which add a rate criterion is a topic of debate. The desired learning outcome is fluent responding, assessed by measures of retention, endurance, stability, and application. The current study examined the effects of these two procedures on fluency outcomes using a matching-to-sample paradigm to train participants to match English to Japanese characters. An explicit FR-3 observing response was added to an accuracy-onl… more

Human concept cognition and semantic relations in the unified medical language system: A coherence analysis.

Description: There is almost a universal agreement among scholars in information retrieval (IR) research that knowledge representation needs improvement. As core component of an IR system, improvement of the knowledge representation system has so far involved manipulation of this component based on principles such as vector space, probabilistic approach, inference network, and language modeling, yet the required improvement is still far from fruition. One promising approach that is highly touted to offer a … more

"Between the Staves" - Adaptations of Debussy's Six épigraphes antiques and Creative Tasks of the Performer

Description: The Six épigraphes antiques represent a cross-section of Debussy's creative output that traces the composer's germ-seed from his original setting of the work in 1901 as incidental music to accompany the recitation of several poems, to the four-hand piano version of 1914, and its consequent reduction for solo piano. What can be gleaned by the methods of derivation from his original sketches to the final, mature works is an understanding of Debussy's use of musical metaphor and his connection to … more

College Student Adaptability and Greek Membership: A Single Institution Case Study

Description: Since the birth of the United States in 1776, Greek-letter societies have been an integral part of American higher education. Research on the impact of Greek membership varies at best, and often is in conflict from study to study. This study surveyed students affiliated with Greek-letter organizations at the University of North Texas. The research examined the college adaptability of Greek students by gender in five areas: Overall adjustment, academic adjustment, personal-emotional adjustment, … more

Anderson Localization in Two-Channel Wires with Correlated Disorder: DNA as an Application

Description: This research studied the Anderson localization of electrons in two-channel wires with correlated disorder and in DNA molecules. It involved an analytical calculation part where the formula for the inverse localization length for electron states in a two-channel wire is derived. It also involved a computational part where the localization length is calculated for some DNA molecules. Electron localization in two-channel wires with correlated disorder was studied using a single-electron tight-bi… more

Computational Studies of Selected Ruthenium Catalysis Reactions.

Description: Computational techniques were employed to investigate pathways that would improve the properties and characteristics of transition metal (i.e., ruthenium) catalysts, and to explore their mechanisms. The studied catalytic pathways are particularly relevant to catalytic hydroarylation of olefins. These processes involved the +2 to +3 oxidation of ruthenium and its effect on ruthenium-carbon bond strengths, carbon-hydrogen bond activation by 1,2-addition/reductive elimination pathways appropriate … more

An empirical investigation of how perceived devaluation and income effects influence consumers' intended utilization of savings from coupon redemption.

Description: Coupons are one of the most popular and attractive tools of promotion. Redeeming coupons makes shoppers feel that they are doing something good for their family's budget, because coupons offer 'savings.' On the other hand, a coupon might have several negative effects on purchase behavior as well, which might 'devalue' the promoted product in the consumer's perception. But a review of the literature shows a lack of attention afforded to the above-mentioned aspects of coupon redemption. In additi… more
