Firm Performance Feedback And Organizational Impression Management: The Moderating Role Of Ceo Overconfidence, Hazel H. Dadanlar, Manisha M. Vaswani, Marwan A. Al-Shammari, Soumendra Nath Banerjee

Management Faculty Publications and Presentations

We propose that while positive performance feedback is positively related to firm sentiment, negative performance feedback is negatively associated with the firm sentiment. Additionally, overconfident Chief Executive Officers (CEOs) will improve the positive relationship between positive performance feedback and firm sentiment and reduce the negative relationship between negative performance feedback and firm sentiment. Using 7,182 firm-year observations for the 2004−2017 period, we show that positive performance feedback positively affects firm sentiment, and negative performance feedback negatively influences firm sentiment. We also found that higher levels of CEO overconfidence will minimize the negative impact of negative performance feedback on firm sentiment. …

The methods and findings presented here …

The Intergenerational Transmission Of Culture Through Attachment-Based Parenting Practices And Their Effect On Child Neurology: A Systematic Review, Elvina Chow

Theses and Dissertations

The process of intergenerational transmission process is complex and involves a dynamic exchange of explicit teachings, implicit cues, and lived experiences within the parent-child relationship. This systematic review examined the intricate relationship between the intergenerational transmission of cultural values, attachment-based parenting, and child neurology through a mixed-methods approach. Findings suggest that culture is transmitted via intergenerational transmission in the parent-child dyad through parental security and trust, adverse childhood experiences (ACEs), and cultural influences on parenting practices. Moreover, the literature suggests that attachment-based parenting affects the intergenerational transmission of culture, values, and beliefs through the parent-child relationship quality, open communication, and …

Systematic Review Of The Risks, Consequences, Protective Factors, And Treatment Of Infidelity For Military Couples, Maria Allyson Ayson

Theses and Dissertations

This systematic review examines literature related to the phenomenon of infidelity in relation to military couples, particularly regarding the risk factors, protective factors, and relational outcomes of infidelity in relation to the military lifestyle. Aspects of this lifestyle, including deployment, relocation, combat exposure, and the plethora of mental health issues subsequent to these experiences, are common instigators of adverse relational events like infidelity, which itself is a catalyst for further relational injury. Furthermore, treatments available for military couples, which have been adapted from various therapy modalities used with civilian couples, are also summarized in this review to consolidate and discuss …

The Violence Of Free Speech And Press Metaphors, Erin C. Carroll

Georgetown Law Faculty Publications and Other Works

Today, our free speech marketplace is often overwhelming, confusing, and even dangerous. Threats, misdirection, and lies abound. Online firestorms lead to offline violence. This Article argues that the way we conceptualize free speech and the free press are partly to blame: our metaphors are hurting us.

The primary metaphor courts have used for a century to describe free speech—the marketplace of ideas—has been linked to violence since its inception. Originating in a case about espionage and revolution, in a dissent written by Oliver Wendell Holmes, a thrice-injured Civil War veteran, the marketplace has been described as a space where competition …

Non-Target Site Mechanisms Of Cross-Resistance Evolution To Florpyrauxifen-Benzyl In 2,4-D-Resistant Palmer Amaranth (Amaranthus Palmeri), Jeong-In Hwang, Jason K. Norsworthy, L. Tom Barber, Thomas R. Butts

Crop, Soil and Environmental Sciences Faculty Publications and Presentations

The evolution of herbicide resistance in weeds can reduce the herbicide’s efficacy, depleting crop yield and quality. Our group previously confirmed 2,4-D resistance in three Palmer amaranth (Amaranthus palmeri S. Watson) populations (R1 to R3). In the current study, the first filial (F₁) seeds of 2,4-D–resistant populations were subjected to screening tests for resistance to other auxin-mimicking herbicides, florpyrauxifen-benzyl (FPB; 30 g ai ha⁻¹) and dicamba (560 g ae ha⁻¹). Dicamba killed all resistant populations. FPB provided 100% control of only the R3 population. Sensitivities to FPB were reduced by 2 and 35 percentage …

Asynchronous Movement Patterns Between Breeding And Stopover Locations In A Long-Distance Migratory Songbird, Theodore Zenzal, Andrea Contina, Hannah Vander Zanden, Leanne Kuwahara, Daniel Allen, Kristen Covino

Faculty Publications

The species-specific migratory patterns and strategies of many songbirds remain unknown or understudied, as research in animal ecology is biased toward the breeding period, with the fewest studies on the migratory period across taxa. Identifying large-scale spatiotemporal migratory patterns is challenging, as individuals within a species may vary in their migratory behavior and strategies. The Yellow Warbler (Setophaga petechia) is a Nearctic-Neotropical migrant that is relatively well studied during the breeding season, but its species-wide migratory patterns remain understudied. Our aim in studying Yellow Warbler movement ecology was to characterize temporal migration patterns during fall migration. We sought to determine …

Andrew Tate, Matt Walsh, And The Discursive Production And Policing Of Gender, Alan J. Bandyk, Alan J. Bandyk

Graduate Student Theses, Dissertations, & Professional Papers

This thesis utilizes the works of Judith Butler, Simone de Beauvoir, Frederic Jameson, and Edward Said in a discourse analysis of influencers and writers in the right wing "manosphere." The figures analyzed herein are Andrew Tate and Matt Walsh. Their rhetoric aims to create a discursive woman who embodies traditional notions of gender and sex that de Beauvoir critiqued in 1949. The constant adherence and reference to a mythical past exhibits ways of thinking that coincide perfectly with Jameson's own theoretical work with the term and its inherent false nostalgia. Tate's and Walsh's efforts also fall into discursive attempts at …

Locating Liability For Medical Ai, W. Nicholson Price Ii, I. Glenn Cohen

Articles

When medical AI systems fail, who should be responsible, and how? We argue that various features of medical AI complicate the application of existing tort doctrines and render them ineffective at creating incentives for the safe and effective use of medical AI. In addition to complexity and opacity, the problem of contextual bias, where medical AI systems vary substantially in performance from place to place, hampers traditional doctrines. We suggest instead the application of enterprise liability to hospitals—making them broadly liable for negligent injuries occurring within the hospital system—with an important caveat: hospitals must have access to the information needed …

Use Of Artificial Intelligence In Drug Development, Louise C. Druedahl, Nicholson Price, Timo Minssen, Dipl Jur, Ameet Sarpatwari

Articles

Considerable focus has been placed on the health care applications of artificial intelligence (AI). Already, machine learning, a subset of AI that involves “the use of data and algorithms to imitate the way that humans learn” has been used to predict diseases, while AI-powered smartphone apps have been developed to promote mental health and weight loss. Owing in part to such successes, the market for AI in health care has been forecasted to increase more than 1000% between 2022 and 2029, from $13.8 billion to $164.1 billion. One area of substantial promise is drug development, which is poised to benefit …

A Fractured Supreme Court: Select Criminal Law And Procedure Cases From The Supreme Court’S 2023-24 Term, Eve Brensike Primus, Jordan Schuler

Articles

In its 2023-2024 Term, the Supreme Court outlined the contours of when a former President of the United States would be immune from criminal prosecution; issued important decisions interpreting the scope of the Cruel and Unusual Punishments Clause, the Double Jeopardy Clause, the Confrontation Clause, and the Second Amendment right to bear arms; decided a number of important statutory interpretation cases; and continued to avoid Fourth Amendment issues, only addressing them in the context of a malicious prosecution charge. Perhaps more striking than the Court’s decisions in these cases, though, was the Justices’ lack of consensus. Of the 16 criminal …

U.S. National Security And Climate Change, Alexandra E. Koch, Nicole K. Carle, Gregory P. Noone

Case Western Reserve Journal of International Law

As sea temperatures rise and natural disasters intensify, it is critical that the U.S. national security strategy actively include plans to account for global climate change and address the complex environmental and humanitarian challenges that parallel and are driven by rising temperatures, such as resource scarcity, forced displacement, and regional instability. Climate change acts as a “threat multiplier for instability” in some of the most volatile regions of the world and can contribute to rising tensions even in historically stable regions. Climate change can also lead to increased vulnerability of military infrastructure and logistics, undermine military readiness, and demand a …

Mechanistic Insight Into Maternal Electronic Cigarette Exposure And Its Effect On Offspring Cerebrovascular And Neurocognitive Health, Amber Victoria Mills

Graduate Theses, Dissertations, and Problem Reports (ETD)

Electronic cigarettes (Ecigs) have replaced smoking within the last decade as the preferred nicotine delivery system because of their advertising to the younger populations. Marketing has sold the idea that use of Ecigs are safer than smoking and this messaging has resonated with youth and other vulnerable populations such as pregnant women. Despite over 2.8 million children under 18 (Annual National Youth Tobacco Survey) deciding to vape, there is little information about what this will do to the next generation. Further, it is that same population that will soon reach an age when they will want to have children. There …

Formulation, Sensory Evaluation, And Physicochemical Assessment Of And Consumer Behavior Toward Novel Energy Bars, Ian Phillip Israelsen

Graduate Theses, Dissertations, and Problem Reports (ETD)

The objectives of this study were to 1) formulate a novel energy bar containing significant macronutrients and calories per serving with favorable ratings from consumers; 2) analyze responses to a consumer preference survey and sensory evaluation of novel energy bars compared to a commercially available energy bar. For the first study, fourteen iterations of an energy bar were synthesized with differing protein sources (whey, soy, pea, hemp), and characteristic variations (nougat, chocolate truffle, peanut butter, double-date caramel). A shortbread base, date caramel, and chocolate coating were included in every bar. Sensory evaluations determined that the most liked variation overall was …

Regulation Of Diabetic Cardiomyopathy Through Mitochondrial Import Of Long Non-Coding Rnas, Andrew Dodge Taylor

Graduate Theses, Dissertations, and Problem Reports (ETD)

Introduction: The leading cause of mortality in patients with diabetes mellitus is heart failure. When mitochondrial health and function is disrupted, cardiac contractile function is compromised. Therefore, understanding mitochondrial regulation may benefit predicting and countering diabetic cardiomyopathy. MicroRNAs (miRNAs) play a crucial role in diabetic cardiac mitochondrial protein expression. Long noncoding RNAs (lncRNAs) have been shown to regulate miRNAs, but not in the mitochondrion. Additionally, it has yet to be confirmed if lncRNAs utilize the same mechanisms for mitochondrial import that miRNAs use, or if lncRNA presence in the mitochondrion fluctuates in diabetic mitochondria like miRNA presence does. The …

Cellular Level Changes Induced In Cancer Cells Due To Microgravity, Sai Deepika Reddy Yaram

Graduate Theses, Dissertations, and Problem Reports (ETD)

The increase in human activity in space has revealed several kinds of physiological challenges brought on by the absence of Earth's gravitational pull. NASA observed that during spaceflight, astronauts experience a 1-1.5% monthly loss in the mineral density of weight-bearing bones, with rehabilitation efforts on Earth often proving ineffective. This issue extends to muscles, the neuro vestibular system, the cardiovascular system, and vision. Cancer has emerged as a significant cause of mortality among astronauts, with studies up to 2017 showing that 41.3% of natural cause deaths among U.S. astronauts were due to cancer, primarily due to space radiation exposure. Cancer …

A Portable, Digital Nucleic Acid Amplification Test For Use At The Point Of Care, Bethany J. Fike

Graduate Theses, Dissertations, and Problem Reports (ETD)

Nucleic acid tests are key tools for the detection and diagnosis of many diseases. In many cases, the amplification of nucleic acids is required to reach a detectable level. Although nucleic acid tests have great success, there is a need to make nucleic acid amplification tests more accessible to a point-of-care (POC) setting for diagnosis, prognosis, and monitoring of infectious diseases. Traditionally, these tests are performed through bulk Polymerase Chain Reaction (PCR) and are monitored in real time with a change in fluorescence intensity. With these bulk testing methods, only a qualitative or semi-quantitative result is possible. For more exact …

The Sex Chromosome Complement And Gut Microbiome Act Independently And Collaboratively To Impart Sex Dimorphisms In Humoral Immunity, Carly J. Amato-Menker

Graduate Theses, Dissertations, and Problem Reports (ETD)

Sex dimorphisms in immunity are well-documented and have significant clinical implications. While the immunomodulatory effects of sex hormones have been extensively documented, recent recognition of the nuanced contributions of the sex chromosome complement (XX vs. XY) and the gut microbiome to immune sex dimorphisms underscores the need for a more comprehensive understanding. Within this context, the work herein focuses on unraveling the individual and collaborative impacts of the sex chromosome complement and gut microbiota on humoral immune activation. We assessed humoral immune responses to immunization with heat-killed Streptococcus pneumoniae (HKSP) in Four Core Genotype (FCG) mice and found elevated IgM-secreting …

Data collected consisted of a survey assessing perceived self-efficacy and mentoring, interviews and documents. Data analysis explored themes related to the perceived academic and professional development of the students through their responses. The research highlights the significance of the mentor-mentee relationship and influence of the mentor on the …

Soil Governance And Private Property, Sarah J. Fox

Utah Law Review

This is an Article about soil. In consequence, it is also an Article about our relationship to land, and about how that relationship can and must change to confront the many environmental crises facing the United States. Questions about our relationship with the physical environment around us necessarily come to the fore in conversations about soil because of its several identities. It is one of Earth’s most precious resources—the substance responsible for allowing plants to grow, filtering pollutants out of water, providing habitat to countless organisms, sequestering carbon, and providing many other valuable functions. Soil also, however, makes up the …

Banning Plastic, Rachael E. Salcido

Utah Law Review

The disgusting nature of plastic pollution has finally captured the attention of policymakers and driven legal change. Local, state, and national bans on various plastic consumer items coupled with voluntary industry switching creates momentum toward a full-scale end to unnecessary plastic products. Bans have the capacity to create an important tipping point. This Article extolls the effectiveness of consumer bans and explores the challenges to achieving this highest level of environmental control. Plastic is essentially pure petroleum.1 Its persistence and destructiveness in the environment presents unique reasons to eliminate its use altogether. Plastics should only be used for essential products …

Is Knowledge Management (Finally) Extractive? – Fuller’S Argument Revisited In The Age Of Ai, Norman Mooradian

Faculty Research, Scholarly, and Creative Activity

Aim/Purpose The rise of modern artificial intelligence (AI), in particular, machine learning (ML), has provided new opportunities and directions for knowledge management (KM). A central question for the future of KM is whether it will be dominated by an automation strategy that replaces knowledge work or whether it will support a knowledge-enablement strategy that enhances knowledge work and uplifts knowledge workers. This paper addresses this question by re-examining and updating a critical argument against KM by the sociologist of science Steve Fuller (2002), who held that KM was extractive and exploitative from its origins. Background This paper re-examines Fuller’s argument …

Results: Fermentation resulted in significantly lower pH and higher titratable acidity in sorghum …

The Challenge Of Securing Future Food Production For Aquaculture Species Under Environmental Change: Enhancing Physiological Performance Under Environmental Stress, Ahmed Salama Ali Abbas

School of Biological and Marine Sciences Theses

Rising sea surface temperatures and ocean acidification present profound challenges for many marine species, leading to cascading effects on ecosystem functionality and food security. Phenotypic plasticity is anticipated to play a key role in helping marine ectotherms maintain performance and acclimate to changes in these global environmental drivers. However, our understanding of phenotypic plasticity in the context of climate change is largely based on short-term studies, with limited ecological relevance, which often overlook some important response modifiers such as environmental context, exposure nature, reproductive modes, and potential trade-offs between fitness components. As a result, the full potential for marine ectotherms …

Ecosystem-Scale Patterns In The Diversity, Seasonal Dynamics And Physiology Of Antagonistic Diatom-Bacteria Interactions In The Western English Channel, Laura Branscombe

School of Biological and Marine Sciences Theses

Diatoms, a major group of marine and freshwater microalgae, are one of the most successful phototrophic organisms in the oceans. Their ubiquity and abundance pins them as important drivers of marine biogeochemical cycles and significant components of marine food webs. Diatoms exist within a complex web of interactions with other microbes, including equally ubiquitous marine bacteria. Interkingdom interactions between diatoms and bacteria are both diverse and numerous, and they underpin the success of diatoms through their resulting impacts on diatom physiology. Interactions between diatoms and antagonistic bacteria are increasingly recognised to significantly impact diatom growth and physiology, and potentially represent …

Mapping The ‘Particlescape’: Diversity And Activity Of Microbial Communities Associated With Particles In The Marine Environment., Cordelia Roberts

School of Biological and Marine Sciences Theses

Particles are hotspots for marine microbial communities and impact ecosystem functioning, including the biological carbon pump. Although particle microbiomes differ across particle composition, type, size, source, and life history, this heterogeneity is often overlooked by using bulk-scale sampling approaches. In addition, knowledge of microbial eukaryotes in particle microbiomes is limited. I broadly set out to investigate how particle associated communities are structured at the macro and micro-scale which may have implications for wider food web interactions and biogeochemical cycling. In independent research chapters, I examined the diversity of bacteria (chapter 1) and activity of microbial eukaryotes associated with organic material …

Intraspecific Differences In The Metabolic Response Of Amphipods To Elevated Co2 And Hypoxia, Emma Ingrid Zandt

School of Biological and Marine Sciences Theses

Periodic episodes of low oxygen (hypoxia) and elevated CO2 (hypercapnia) accompanied by low pH occur naturally in Norwegian fjord systems. Under the influence of climate change, the geographic range and intensity of hypoxia and hypercapnia are predicted to increase, especially considering the phenomenon of Arctic amplification. To examine the metabolic variability and physiological capabilities of amphipods to these stressors, a series of physiological measurements were performed on latitudinal subpopulations (60° and 69°) of the amphipod Echinogammarus marinus, acclimated to different natural thermal regimes. The effects of elevated pCO2 and hypoxia, separate and together, on thermal sensitivity (Q10), metabolic rate, activation …
