    Comparative analysis of college athletics programs’ websites: Name-Image-Likeness content
    (Wichita State University, 2024-05-10) Racy, Tyler
    This study is about potential variances in the presentation of NIL information on college athletic program websites across different divisions and conferences. This paper will examine the websites of member institutions from these NCAA conferences: Big 10, AAC, & MIAA.

    Normal cognitive test scores cannot be interpreted as accurate measures of ability in the context of failed performance validity testing: A symptom- and detection-coached simulation study
    (Routledge, 2021-05-16) Martinez, Karen A.; Sayers, Courtney; Hayes, Charles A.; Martin, Phillip K.; Clark, Charles B.; Schroeder, Ryan W.
    Introduction: While use of performance validity tests (PVTs) has become a standard of practice in neuropsychology, there are differing opinions regarding whether to interpret cognitive test data when standard scores fall within normal limits despite PVTs being failed. This study is the first to empirically determine whether normal cognitive test scores underrepresent functioning when PVTs are failed. Method: Participants, randomly assigned to either a simulated malingering group (n = 50) instructed to mildly suppress test performances or a best-effort/control group (n = 50), completed neuropsychological tests which included the North American Adult Reading Test (NAART), California Verbal Learning Test – 2nd Edition (CVLT-II), and Test of Memory Malingering (TOMM). Results: Groups were not significantly different in age, sex, education, or NAART predicted intellectual ability, but simulators performed significantly worse than controls on the TOMM, CVLT-II Forced Choice Recognition, and CVLT-II Short Delay Free Recall. The groups did not significantly differ on other examined CVLT-II measures. Of simulators who failed validity testing, 36% scored no worse than average and 73% scored no worse than low average on any of the examined CVLT-II indices. Conclusions: Of simulated malingerers who failed validity testing, nearly three-fourths were able to produce cognitive test scores that were within normal limits, which indicates that normal cognitive performances cannot be interpreted as accurately reflecting an individual’s capabilities when obtained in the presence of validity test failure. At the same time, only 2 of 50 simulators were successful in passing validity testing while scoring within an impaired range on cognitive testing. This latter finding indicates that successfully feigning cognitive deficits is difficult when PVTs are utilized within the examination.

    Comparison of amorphous iridium water-oxidation electrocatalysts prepared from soluble precursors
    (American Chemical Society, 2012-07-16) Blakemore, James D.; Schley, Nathan D.; Kushner-Lenhoff, Maxwell N.; Winter, Andrew M.; D'Souza, Francis; Crabtree, Robert H.; Brudvig, Gary W.
    Electrodeposition of iridium oxide layers from soluble precursors provides a route to active thin-layer electrocatalysts for use on water-oxidizing anodes. Certain organometallic half-sandwich aqua complexes of iridium form stable and highly active oxide films upon electrochemical oxidation in aqueous solution. The catalyst films appear as blue layers on the anode when sufficiently thick, and most closely resemble hydrous iridium(III,IV) oxide by voltammetry. The deposition rate and cyclic voltammetric response of the electrodeposited material depend on whether the precursor complex contains a pentamethylcyclopentadieneyl (Cp*) or cyclopentadienyl ligand (Cp), and do not match, in either case, iridium oxide anodes prepared from non-organometallic precursors. Here, we survey our organometallic precursors, iridium hydroxide, and pre-formed iridium oxide nanoparticles. From electrochemical quartz crystal nanobalance (EQCN) studies, we find differences in the rate of electrodeposition of catalyst layers from the two half-sandwich precursors; however, the resulting layers operate as water-oxidizing anodes with indistinguishable overpotentials and HID isotope effects. Furthermore, using the mass data collected by EQCN and not otherwise available, we show that the electrodeposited materials are excellent catalysts for the water-oxidation reaction, showing maximum turnover frequencies greater than 0.5 mol O-2 (mol iridium)(-1) s(-1) and quantitative conversion of current to product dioxygen. Importantly, these anodes maintain their high activity and robustness at very low iridium loadings. Our organometallic precursors contrast with pre-formed iridium oxide nanoparticles, which form an unstable electrodeposited material that is not stably adherent to the anode surface at even moderately oxidizing potentials.

    Nanoporous impedemetric biosensor for detection of trace atrazine from water samples
    (Elsevier, 2012-02-15) Pichetsurnthorn, Pie; Vattipalli, Krishna; Prasad, Shalini
    Trace contamination of ground water sources has been a problem ever since the introduction of high-soil-mobility pesticides, one such example is atrazine. In this paper we present a novel nanoporous portable bio-sensing device that can identify trace contamination of atrazine through a label-free assay. We have designed a pesticide sensor comprising of a nanoporous alumina membrane integrated with printed circuit board platform. Nanoporous alumina in the biosensor device generates a high density array of nanoscale confined spaces. By leveraging the size based immobilization of atrazine small molecules we have designed electrochemical impedance spectroscopy based biosensor to detect trace amounts of atrazine. We have calibrated the sensor using phosphate buffered saline and demonstrated trace detection from river and bottled drinking water samples. The limit of detection in all the three cases was in the femtogram/mL (fg/mL) (parts-per-trillion) regime with a dynamic range of detection spanning from 10 fg/mL to 1 ng/mL (0.01 ppt to 1 ppm). The selectivity of the device was tested using a competing pesticide; malathion and selectivity in detection was observed in the fg/mL regime in all the three cases.

    Charge stabilization in a closely spaced ferrocene-boron dipyrrin-fullerene triad
    (Royal Society of Chemistry, 2010-05-21) Wijesinghe, Channa A.; El-Khouly, Mohamed E.; Blakemore, James D.; Zandler, Melvin E.; Fukuzumi, Shunichi; D'Souza, Francis
    New molecular triads composed of closely spaced ferrocene-boron dipyrrin-fullerene, 1 and triphenylamine-boron dipyrrin-fullerene, 2 are synthesized, and photoinduced electron transfer leading to charge stabilization is demonstrated using a femtosecond transient spectroscopic technique.
