Does Contingent Reward Leadership Enhance Or Diminish Team Creativity? It Depends On Leader (Un-) Predictability, Debjani Ghosh, Martin Buss, Amita Shivhare

Management Faculty Publications

Although prior research has shown that reward provision might sometimes increase creativity, little is known about how leadership that clarifies effort-reward contingencies (i.e., contingent reward leadership) is related to team creativity. Drawing on the theory of learned industriousness, we argue that contingent reward leadership can enhance team knowledge exchange and, in turn, team creative performance. However, we propose that this relationship is moderated by leader unpredictability, which can create uncertainty about resource allocation, thereby undermining the otherwise positive effect of contingent reward leadership. In a two-source, lagged design (three-wave) field study with data from 60 organizational teams, we found a …

Robo-Advisers And Investor Behavior, Benjamin Loos, Pengfei Ma, Alessandro Previtero, Andres Hackethal

Sim Kee Boon Institute for Financial Economics

Using data from a large German retail bank, we investigate the effects of the introduction of a robo-advisory tool on clients’ portfolios. Robo clients experience a significant increase in financial risk-taking and improve portfolio efficiency along several dimensions (more diversification, less home bias, more investment in passive funds, reduced investment fees). Our evidence is consistent with robo-advisers being a more cost-effective approach for offering financial advice, especially to less sophisticated investors.

Meta-Analytic Investigations Of Team Development Interventions And Effectiveness, Sydney Begerowski

All Dissertations

Team development interventions (TDIs) are evidenced-based best practices that improve performance trajectories of teams. To date, various independent studies have demonstrated the effectiveness of one type of TDI in improving effectiveness, but there has yet to be a cross-intervention assessment. Accordingly, the goal of this dissertation was to explore a subset of TDIs (team charters, team training, team debriefing) from a comparative lens. First, I conducted a series of pairwise meta-analyses across team charters, team training, and team debriefing to establish a TDI-effectiveness relationship. Findings were inconclusive regarding team charters, but suggested that team training and team debriefing significantly improve …

Phylogenetics And Biogeography Of Appalachian Trechus (Coleoptera: Carabidae), Patricia Wooden

All Dissertations

Insects have long been used as tools for understanding the health of the natural world and how changes to climate, landscape, and human interaction have affected the communities those environments support. The Appalachian Mountains, located in eastern North America, is the oldest mountain range on the continent, and during its lifespan it has supported an abundance of microhabitats and endemic species to fill them. Conservationists must balance the need to preserve the diversity that is known and continue to explore the region for new taxa, often with limited budget and expertise. A genus of small carabids, Trechus Clairville, may aid …

Reinforcement Learning-Based Energy Management For Electric Vehicle Application, Yiming Ye

All Dissertations

The increasing concerns about transportation pollution and fossil fuel depletion motivate many studies on vehicle electrification and advanced energy-saving propulsion systems. When Comparing with traditional internal combustion engine vehicles, electrified vehicles, such as battery and supercapacitor electric vehicles, are equipped with more than one power source in the hybrid propulsion system, which can save more energy through efficient power combinations. Lithium-ion batteries are the preferred choice for energy storage in electric vehicles due to their superior energy density and cost-effectiveness. Nevertheless, matching the required power input and output leads to in an unwanted growth in the size of the battery, …

By examining the diffusion of COVID-19 policies, historical marker modifications, and the implementation of eGovernment services, this research identifies a novel mechanism of policy diffusion that is significantly influenced by political party lines. The study employs a comprehensive methodological approach, incorporating case studies and quantitative analysis to examine policy implementation across politically diverse local governments. The findings reveal that political affiliation profoundly impacts policy choices, with distinct patterns of policy …

A Rhetorical-Sociological Understanding Of Emotion, Amy Boone

All Dissertations

This project presents a rhetorical-sociological understanding of emotion while foregrounding the place and role of language. Born from Sara Ahmed’s work in The Cultural Politics of Emotion, it presents a simplified equation (contact + orientation = emotion) as both a prescriptive and descriptive formula for making sense of human emotional experience. Starting with an exploration of the difficult-to-understand affect system, this dissertation identifies both rhetoric and affect as energies which cannot be understood apart from their traces, the things they move, produce, and become. As a way to get at these often-invisible forces, two trace studies are conducted which explore …

Exploring Novel Nutrient Acquisition Mechanisms For Maintaining Energy Metabolism In Toxoplasma Gondii, Melanie Key

All Dissertations

Toxoplasma gondii is an infectious intracellular parasite that establishes infection within various mammalian hosts, including humans. Toxoplasma infects approximately one-third of the global population, making it an impactful pathogen of study. T. gondii is the causative agent of toxoplasmosis, an opportunistic infection that causes severe illness or fatality in immunocompromised individuals or pregnant women. The parasite possesses a very effective invasion strategy, allowing it to cross different tissue types to disseminate infection across the placental and blood-brain barrier. Although there are a few treatments for acute toxoplasmosis, these drugs can produce adverse side effects. These options are not effective against …

An Exploration Of The Efficacy Of Virtual Agents Within Smartphone Mental Health Applications, Stephanie Six

All Dissertations

The prevalence of depression in the U.S. has increased over the past decade, leading to an all-time-high during the COVID-19 pandemic (WHO, 2022). With this increase, the number of mental health applications (MHealth apps) on virtual e-stores increases in tandem. Despite this expanding number of MHealth apps, few demonstrate a foundation in empirical research. One design factor that may influence usability and effectiveness is the inclusion of virtual agents. Three studies were conducted to investigate users’ preferences for a variety of characteristics associated with virtual agents. In Experiment 1, users completed a single-session, three-stage CBT-based interaction with virtual characters and …

Evolution And Biogeography Of High Appalachian Rove Beetles (Staphylinidae), Adam Haberski

All Dissertations

The southern Appalachian Mountains are a region of great species richness and a center of endemism in many taxa, including flightless arthropods. High elevation refugia have facilitated the persistence of ancient lineages (paleoendemism) and in situ speciation (neoendemism), but their ubiquity, timing, and relative importance is unknown. Congruent patterns among co-distributed, but independent taxa might illuminate common drivers of Appalachian endemism. In this dissertation, I investigated the influence of allopatric speciation, geography, and paleoclimate events on the diversification of endemic species in two genera of rove beetles (Coleoptera, Staphylinidae), Lathrobium Gravenhorst and Ischnosoma Stephens, using an integrative morphological and molecular …

Real-Time Degradation Abatement Framework For Energy Storage System In Automotive Application Using Data-Driven Approaches, Laxman Timilsina

All Dissertations

The increasing popularity of electric vehicles (EVs) is driven by their compatibility with sustainable energy goals. However, the decline in the performance of energy storage systems, such as batteries, due to their degradation puts EVs and hybrid electric vehicles (HEVs) at a disadvantage compared to traditional internal combustion engine (ICE) vehicles. The batteries used in these vehicles have limited life. The degradation of the battery is accelerated by the operating conditions of the vehicle, which further reduces its life and increases the reliability and economic concerns for the vehicle’s operation.

Assessing Consumer Willingness To Pay For Zinc-Biofortified Rice – The Case Of Colombia, Sara Ann Oswalt

Graduate Theses and Dissertations

Hidden hunger, a form of undernourishment caused by micronutrient deficiencies, remains a critical global challenge affecting billions worldwide. Biofortification of staple crops, such as rice, offers a promising solution to address this problem. However, changes in the physical and culinary characteristics due to biofortification may hinder consumer acceptance and limit the benefits of this approach. This research explores consumer preferences and willingness to pay (WTP) for zinc-biofortified rice in Cartagena, Colombia. A non-hypothetical experimental auction, including 400 consumers in five different locations within Cartagena, was conducted to analyze the impact of information, socioeconomic factors, and consumer nutrition knowledge on WTP …

Cultivating Atmosphere In Independent Coffee Shops: Reflections On How Atmospheres Are Created Through Sensory Experiences, Brooke Bierhaus Sutton

Graduate Theses and Dissertations

Affective atmosphere is a fundamental component to the allure of coffee shops that is cultivated through sensory experience. In this thesis I examine how the sensory experience of sight, sound, smell, taste, and touch, create atmospheres in coffee shops. I ask, “how do coffee shops cultivate an affective atmosphere?” Through an exploration of material culture, design, affect, and the intentional production of third places, I illustrate the ways in which independent coffee shops have their own unique identities and atmospheres. By using memoir and reflexive analysis of my decade in global coffee culture, as well as an extensive literary review, …

The Educator Labor Market In Times Of Change: Lessons From The Covid-19 Pandemic, Andrew Mitchell Camp

Graduate Theses and Dissertations

The COVID-19 pandemic placed an undeniable burden onto the teaching profession which already faced levels of prestige and interest at 50-year lows. The strains of the pandemic resulted in educators reporting higher levels of job-related stress and burnout and exacerbated concerns about potential teacher shortages. This dissertation leverages administrative data from Arkansas to better understand challenges facing the teacher workforce following COVID-19 and evaluate two increasingly policies aimed at the teacher workforce. In the first chapter, I provide evidence that teacher turnover was relatively stable during the first two years (2020-21 and 2021-22) of the COVID-19 pandemic before a notable …

Do Executive Functions Buffer Against Covid-19 Fear And Stress? A Latent Variable Approach, Tina Li Yi Ng, Nadyanna M. Majeed, Verity Yu Qing Lua, Andree Hartanto

Research Collection School of Social Sciences

Levels of COVID-19 stress have soared worldwide as a result of the pandemic. Given the pernicious psychological and physiological effects of stress, there is an urgent need for us to protect populations against the pandemic’s psychological impact. While there exists literature documenting the prevalence of COVID-19 stress among various populations, insufficient research has investigated psychological factors that might mitigate this worrying trend. To address this gap in the literature, the current study seeks to examine executive functions as a potential cognitive buffer against COVID-19 stress. To do so, the study adopted a latent variable approach to examine three latent factors …

Can Confidence Influence Persuasiveness In Disagreements By Conveying Competence Versus Dominance? The Moderating Role Of Competitiveness, Laura Rees, Ming-Hong Tsai, Shirli Kopelman, Hsiu-Hua Hu

Research Collection School of Social Sciences

Research has demonstrated that confident individuals gain social influence because their confidence signals competence rather than dominance in settings in which they do not experience a disagreement with others. We extend this research by exploring felt competitiveness, as reflected by perceptions of goal opposition between perceivers and others. In settings where people experience a disagreement, we explore the impact of felt competitiveness on the association between expressed confidence and social perceptions of the expresser’s competence and dominance, and how these shape persuasiveness. We conducted a field study examining dyadic interactions between coworkers (Study 1) and two experimentsmanipulating competitiveness and confidence …

2020-Current year OA Pubs

INTRODUCTION: Person-centred care (PCC) has been recognized as a critical element in delivering quality and responsive health services. The patient-provider relationship, conceptualized at the core of PCC in multiple models, remains largely unexamined in HIV care. We conducted a systematic review to better understand the types of PCC interventions implemented to improve patient-provider interactions and how these interventions have improved HIV care continuum outcomes and person-reported outcomes (PROs) among people living with HIV in low- and middle-income countries.

METHODS: We searched databases, conference proceedings and conducted manual targeted searches to identify randomized trials and observational studies published up to January …

Then, a MAGDM model is developed in terms of SVNCM energy and its score function in a SVNCM scenario and also its decision algorithm is provided to solve MAGDM problems with SVNCMs. Finally, the developed MAGDM model is applied in the school site selection problem as an actual example, then the comparative investigation of the decision results in …

Coarctation Duration And Severity Predict Risk Of Hypertension Precursors In A Preclinical Model And Hypertensive Status Among Patients, Arash Ghorbannia, Hilda Jurkiewicz, Lith Nasif, Abdillahi Ahmed, Jennifer Co-Vu, Mehdi Maadooliat, Ronald K. Woods, John F. Ladisa Jr.

Mathematical and Statistical Science Faculty Research and Publications

BACKGROUND:

Coarctation of the aorta (CoA) often leads to hypertension posttreatment. Evidence is lacking for the current >20 mm Hg peak-to-peak blood pressure (BP) gradient (BPGpp) guideline, which can cause aortic thickening, stiffening, and dysfunction. This study sought to find the BPGpp severity and duration that avoid persistent dysfunction in a preclinical model and test if predictors translate to hypertension status in patients with CoA.

METHODS:

Rabbits (n=75; 5–12/group) were exposed to mild, intermediate, or severe CoA (≤12, 13–19, ≥20 mm Hg BPGpp) for ≈1, 3, or 22 weeks using dissolvable and permanent sutures with thickening, stiffening, contraction, and endothelial …

Government Misinformation Platforms, Janet Freilich

Faculty Scholarship

There is a harmful mismatch between how information published by the government is perceived-as highly trustworthy-and the reality that it is often not. This Article shows that the government frequently collects information from third party private entities and publishes it with no review or vetting. Although this information is riddled with errors and inaccuracies, scholars, policymakers, and the public treat the information with unwarranted confidence because it derives from the government. Further, institutional imprimatur (and consequent trust) attaches to information even tangentially associated with the government and to information where the government explicitly disclaims review.

This Article highlights the ubiquity …

Characterizing Modulators Of Protease-Activated Receptors With A Calcium Mobilization Assay Using A Plate Reader, Jacob T. Derousse, Chris Dockendorff

Chemistry Faculty Research and Publications

Changes in calcium concentration in cells are rapidly monitored in a high-throughput fashion with the use of intracellular, fluorescent, calcium-binding dyes and imaging instruments that can measure fluorescent emissions from up to 1,536 wells simultaneously. However, these instruments are much more expensive and can be challenging to maintain relative to widely available plate readers that scan wells individually. Described here is an optimized plate reader assay for use with an endothelial cell line (EA.hy926) to measure the protease-activated receptor (PAR)-driven activation of G_αq signaling and subsequent calcium mobilization using the calcium-binding dye Fluo-4. This assay has been used to …
