Ceo Characteristics And Risk-Taking Under Economic Policy Uncertainty, Ivan Stetsyuk, Ayca Altintig, Kerim Peren Arin, Moo Sung Kim

All Works

This paper investigates the effects of such CEO characteristics as gender, age, and education on the CEOs’ risk-taking behavior during periods of economic policy uncertainty. The paper utilizes Execucomp, BoardEx, and Compustat data from 2005 to 2017 in order to give a novel perspective on how CEO characteristics may provide differing risk-taking positions when faced with varying levels of uncertainty. The results offer robust evidence that older CEOs generally take less risk—regardless of the level of economic policy uncertainty. However, more educated CEOs take less risk only during economically uncertain times. The results also indicate that while female CEOs tend …

How Reuse Rooms Can Reduce Waste On University And College Campuses, Zoe Slabodnik

University Honors Theses

This undergraduate honors thesis discusses the importance of how reuse rooms on university and college campuses can reduce waste by providing an alternative method of disposal other than landfills. There is currently no definition in use that exists for the term reuse room. This thesis defines a reuse room as a community room where anyone with access can donate and take free items that can be reused, recycled, repurposed, repaired and reworn. The goal of a reuse room is to encourage waste reduction, promote and destigmatize the use of second-hand materials, and save money and items from going to landfills. …

Enhancing Robustness Of Machine Learning Models Against Adversarial Attacks, Ronak Guliani

University Honors Theses

Machine learning models are integral for numerous applications, but they remain increasingly vulnerable to adversarial attacks. These attacks involve subtle manipulation of input data to deceive models, presenting a critical threat to their dependability and security. This thesis addresses the need for strengthening these models against such adversarial attacks. Prior research has primarily focused on identifying specific types of adversarial attacks on a limited range of ML algorithms. However, there is a gap in the evaluation of model resilience across algorithms and in the development of effective defense mechanisms. To bridge this gap, this work adopts a two-phase approach. First, …

Moss Biomonitoring Of Lead Emissions From Hillsboro Airport, Daria Kolpakov

University Honors Theses

The objective of this experiment was to use biomonitoring as a method to determine lead concentration levels around Hillsboro Airport in Hillsboro, Oregon. Twenty-two samples were collected within a 2 km radius around Hillsboro Airport using a randomized sampling strategy. The concentrations of lead within the samples were determined using ICP-MS. The average lead concentration was (2.8 ± 5.0) mg/kg with a peak value of 21.6 mg/kg 0.57 km from Hillsboro Airport. As the average lead concentration was substantially skewed, Hillsboro Airport is likely to be the source of the lead increase.

Abusive Abbots And Malevolent Monks: Monasteries And Violence In The Early Anglo-Norman Period, Timothy B. Smart Jr.

University Honors Theses

This investigation examines the conduct of abbots and monasteries from 1066 to 1087 in the context of violence and monasteries. It analyzes monastic chronicles and Anglo-Norman histories. The two historiographical lineages that emerge: the Norman Conquest and religious warfare. After the initial conquest in 1066, four native abbots offer insight into a range of local monastic behaviors during the early years of Norman rule. The Normans, in their combat against rebellious monasteries, developed procedures to remove local abbots in 1070. This connection between rebellions and monasteries drove the militarization of monasteries by both the Normans and the Anglo-Saxons. The militarization …

Pt-Symmetry And Eigenmodes, Tamara Gratcheva

University Honors Theses

Spectra of systems with balanced gain and loss, described by Hamiltonians with parity and time-reversal (PT) symmetry is a rich area of research. This work studies by means of numerical techniques, how eigenvalues and eigenfunctions of a Schrodinger operator change as a gain-loss parameter changes. Two cases on a disk with zero boundary conditions are considered. In the first case, within the enclosing disk, we place a parity (P) symmetric configuration of three smaller disks containing gain and loss media, which does not have PT-symmetry. In the second case, we study a PT-symmetric configuration …

The Impact Of Grade-Level Switching In The Elementary School Setting, Christine Priester

School of Medicine Faculty Publications

This study aims to focus on developing a food supplement for the geriatric population using disposal mushrooms, oats, and lactose-free milk powder. Lactose intolerance is most common in older adults, raising the demand for lactose-free foods. One of the major global challenges currently faced by humankind is food waste (FW). Most of the food that is produced for human consumption has not been utilized completely (1/3rd-1/2 unutilized), resulting in agricultural food waste. Mushrooms are highly valuable in terms of their nutritional value and medicinal properties; however, a significant percentage of mushroom leftovers are produced during mushroom production that do not …

The Criminal Trajectory Of Paraphilic Noncontact Sexual Offenders: An Exploratory Study In An Incarcerated United States Sample, Emma F. Collie

Student Theses

Despite the misconception, many sexual offenses do not involve physical contact with a victim. Research indicates that exhibitionism, a noncontact offense, is the most reported sex crime. While some research has demonstrated the escalation from noncontact to contact offending, much of the data is outdated or used small samples. This study seeks to build upon the literature by examining archival records of 3,175 sex offenders incarcerated in the U.S. This study examined the number of offenders who progressed from noncontact to contact offenses and compared the demographic, crime, and risk characteristics of those convicted of noncontact offenses and those convicted …

Incarceration Vs Treatment: Is One More Effective Than The Other In Preventing Recidivism For Drug Abuse?, Scott G. Kang

Student Theses

This study aims to determine the most effective approach for reducing recidivism among drug offenders, comparing incarceration with treatment. Two hypotheses were formulated for this research: 1) Drug offenders undergoing residential treatment will experience lower recidivism rates compared to those sentenced to incarceration. 2) Extended therapeutic treatment is more likely to positively influence behavior change among drug abusers compared to longer prison sentences. These hypotheses were tested using data from 263 participants in the Drug Treatment Alternative-to-Prison (DTAP) program, analyzed through logistic regression in SPSS.

Three-Dimensional Imaging Studies In Mice Identify Cellular Dynamics Of Skeletal Muscle Regeneration, Brittany C. Collins, Jacob B. Shapiro, Mya M. Scheib, Robert V. Musci, Mayank Verma, Gabrielle Kardon

Health and Human Sciences Faculty Works

The function of many organs, including skeletal muscle, depends on their three-dimensional structure. Muscle regeneration therefore requires not only reestablishment of myofibers but also restoration of tissue architecture. Resident muscle stem cells (SCs) are essential for regeneration, but how SCs regenerate muscle architecture is largely unknown. We address this problem using genetic labeling of mouse SCs and whole-mount imaging to reconstruct, in three dimensions, muscle regeneration. Unexpectedly, we found that myofibers form via two distinct phases of fusion and the residual basement membrane of necrotic myofibers is critical for promoting fusion and orienting regenerated myofibers. Furthermore, the centralized myonuclei characteristic …

The Divine Stakes Of Human Freedom: Jonas In Dialogue With Schelling, Ian Alexander Moore

Philosophy Faculty Works

In a recent article, Lore Hühn calls for a comprehensive study of the parallels between Schelling’s critique of the will, on the one hand, and the philosophies of nature and technology developed in the twentieth century by students of Heidegger such as Hannah Arendt, Günther Anders, and Hans Jonas, on the other. Hühn notes, in particular, that:

essential moments of Jonas’s ethics of responsibility, with its critique of classical metaphysics’ neglect of the body and nature, cannot be understood without the background of Schelling; this holds as well for Jonas’s speculative figure of the self-retraction of God and for his …

Unanswered Calling: The Dynamics Of Occupational Calling Misalignment Between Leader And Follower, Hilda Obiri-Yeboah

Theses and Dissertations

Emerging research about occupational calling has shifted from occupational psychology to the organizational behavior field. However, the current research mostly focuses on individual calling but ignores the dynamics between varying levels of leader and member occupational calling interactions and potential outcomes. Guided by Social Exchange Theory and leader-follower fit, this thesis investigates four leader-follower occupational calling alignment and misalignment situations and their differentiated attitudinal and behavioral outcomes. Moreover, it identifies important boundary conditions that mitigate the negative effects of the misalignment. This paper synthesizes existing literature and presents a comprehensive model to understand occupational calling's impact on leader-follower dynamics. It …
