Teaching Students How To Think, Not What To Think: Pedagogy And Political Psychology, Gabriel M. Velez, Seamus A. Power

College of Education Faculty Research and Publications

Academia is often critiqued as an “ivory tower” where research, thinking, and teaching are isolated from the complexity and everyday experience of so many people. As instructors of political and other psychology courses, we strive to break down these barriers and engage with the dynamic and nuanced nature of phenomena as situated in lived social and political contexts. In this report, we unpack and detail how we strive to achieve this goal by expanding on Plous’ articulation of action teaching (2012). We first define our pedagogical focus on active engagement, critical thinking, and staying on the move between multiple perspectives. …

Wellness Measurement, Timothy P. Melchert

College of Education Faculty Research and Publications

Incorporating wellness into considerations of health, healthcare, and social policy has reached an exciting point. Aristotle, Buddha, and other philosophers, sages, and religious leaders throughout history developed great insights into the topic, but only in recent decades has the construct of wellness been examined and clarified through systematic empirical research. There are still major debates regarding several aspects of the topic, but it is now widely considered a measurable construct that should play a role in healthcare and social policy. This volume represents another step forward in bringing wellness into the mainstream of health and healthcare.

Wellness often means different …

To make these calculations numerically affordable, a new approach was developed which employs one vibrational basis set optimized for a typical rotational excitation (J,Λ), to run coupled rotation–vibration calculations at several …

Route Exploration And Synthesis Of The Reported Pyridone-Based Pdi Inhibitor Stk076545, Eric Greve, Sergey V. Lindeman, Christina Scartelli, Lin Lin, Robert Flaumenhaft, Chris Dockendorff

Chemistry Faculty Research and Publications

The enzyme protein disulfide isomerase (PDI) is essential for the correct folding of proteins and the activation of certain cell surface receptors, and is a promising target for the treatment of cancer and thrombotic conditions. A previous high-throughput screen identified the commercial compound STK076545 as a promising PDI inhibitor. To confirm its activity and support further biological studies, a resynthesis was pursued of the reported β-keto-amide with an N-alkylated pyridone at the α-position. Numerous conventional approaches were complicated by undesired fragmentations or rearrangements. However, a successful 5-step synthetic route was achieved using an aldol reaction with an α-pyridone allyl …

Chemistry Faculty Research and Publications

Two mononuclear iron(II)–thiolate complexes have been prepared that represent structural models of the nonheme iron enzymes EgtB and OvoA, which catalyze the O₂-dependent formation of carbon–sulfur bonds in the biosynthesis of thiohistidine compounds. The series of Fe(II) complexes reported here feature tripodal N₄ chelates (L^A and L^B) that contain both pyridyl and imidazolyl donors (L^A = (1H-imidazol-4-yl)-N,N-bis((pyridin-2-yl)methyl)methanamine; L^B = N,N-bis((1-methylimidazol-2-yl)methyl)-2-pyridylmethylamine). Further coordination with monodentate aromatic or aliphatic thiolate ligands yielded the five-coordinate, high-spin Fe(II) complexes [Fe^II(L^A)(SMes)]BPh …

Voltammetry And Spectroelectrochemistry Of Tcnq In Acetonitrile/Rtil Mixtures, Abderrahman Atifi, Michael D. Ryan

Chemistry Faculty Research and Publications

Understanding the solvation and ion-pairing interactions of anionic substrates in room-temperature ionic liquids (RTIL) is key for the electrochemical applications of these new classes of solvents. In this work, cyclic voltammetry and visible and infrared spectroelectrochemistry of tetracyanoquinodimethane (TCNQ) was examined in molecular (acetonitrile) and RTIL solvents, as well as mixtures of these solvents. The overall results were consistent with the formation of RTIL/acetonitrile nanodomains. The voltammetry indicated that the first electrogenerated product, TCNQ⁻, was not incorporated into the RTIL nanodomain, while the second electrogenerated product, TCNQ²⁻, was strongly attracted to the RTIL nanodomain. The visible …

Enhanced Light Harvesting Ability In Zeolitic Imidazolate Frameworks Through Energy Transfer From Cds Nanowires, Yixuan Zhou, Wenhui Hu, Sizhuo Yang, Jier Huang

Chemistry Faculty Research and Publications

Zeolitic imidazolate frameworks (ZIFs) represent a novel class of porous crystalline materials that have demonstrated potential as light harvesting materials for solar energy conversion. In order to facilitate their application in solar energy conversion, it is necessary to expand their absorption further into the realm of the solar spectrum. In this work, we report the incorporation of semiconductor cadmium sulfide nanowires (CdS NWs) into ZIF-67 (CdS@ZIF-67), where a broader region of the solar spectrum can be absorbed by CdS NWs and relayed to ZIF-67 through an energy transfer (EnT) process. Using steady-state emission and time resolved emission and absorption spectroscopy, …

Adiabatic Trajectory Approximation Within The Framework Of Mixed Quantum/Classical Theory, Bikramaditya Mandal, Alexander Semenov, Dmitri Babikov

Chemistry Faculty Research and Publications

A hierarchy of approximate methods is proposed for solving the equations of motion within a framework of the mixed quantum/classical theory (MQCT) of inelastic molecular collisions. Of particular interest is a limiting case: the method in which the classical-like equations of motion for the translational degrees of freedom (scattering) are decoupled from the quantum-like equations for time evolution of the internal molecular states (rotational and vibrational). In practice, trajectories are pre-computed during the first step of calculations with driving forces determined solely by the potential energy surface of the entrance channel, which is an adiabatic trajectory approximation. Quantum state-to-state transition …

Chemistry Faculty Research and Publications

1T-MoS₂ and single-atom modified analogues represent a highly promising class of low-cost catalysts for hydrogen evolution reaction (HER). However, the role of single atoms, either as active species or promoters, remains vague despite its essentiality toward more efficient HER. In this work, we report the unambiguous identification of Ni single atom as key active sites in the basal plane of 1T-MoS₂ (Ni@1T-MoS₂) that result in efficient HER performance. The intermediate structure of this Ni active site under catalytic conditions was captured by in situ X-ray absorption spectroscopy, where a reversible metallic Ni species (Ni⁰) …

A Review Of Minority Stress As A Risk Factor For Cognitive Decline In Lesbian, Gay, Bisexual, And Transgender (Lgbt) Elders, Anthony N. Correro, Kristy A. Nielson

Psychology Faculty Research and Publications

Lesbian, gay, bisexual, and transgender (LGBT) older adults comprise a unique and growing subset of the aging population. The historical context in which they came of age was imbued with victimization and discrimination. These experiences are subjectively stressful and collectively known as minority stress. Older LGBT adults continue to face stressors related to their gender and sexual identities in their daily lives. Importantly, chronic minority stress (CMS), like other forms of chronic stress, is harmful to health and well-being. CMS contributes to LGBT health disparities, including cardiovascular disease and depression, conditions that in turn increase risk for premature cognitive decline. …

Depression And Perceived Stress As Mediators Between Racial Microaggressions And Somatic Symptoms In College Students Of Color, Susan Torres-Harding, Lucas Torres, Elaine Yeo

Psychology Faculty Research and Publications

The current study examined the ability of mental health indicators, namely depression and perceived stress, to mediate the relationship between racial microaggressions and health among a racially/ethnically diverse sample of 467 college students of color. Consistent with what was hypothesized, the main findings revealed that depression and perceived stress mediated the relationships between types of racial microaggressions, specifically low-achieving, invisibility, and criminality, and somatic symptoms. The study results suggest that there may be multiple pathways by which specific racial microaggressions might be associated with psychological and somatic health indicators.
