A Semi-Analytic Valuation Of American Options Under A Two-State Regime-Switching Economy, Xiaoping Lu, Endah Putri

Faculty of Engineering and Information Sciences - Papers: Part B

In this study, we develop a semi-analytic method to evaluate American options under a two-state regime-switching economy. The two free boundaries corresponding to the states divide the pricing domain into two regions: a common continuation region and a transition region. Non-linear partial differential equation (PDE) systems are derived under the Black-Scholes framework for each region. The Laplace transform method is used to solve the PDE systems. Equations for determining the optimal exercise prices are obtained analytically and solved numerically in the Laplace space. A numerical inversion technique is then used to obtain the free boundaries and the option prices in …

Attracting People And Potential To Missouri And The Region By Metro Status, William H. Rogers

Center for Applied Economics

This report summarizes the Heartland’s recent economic performance relative to the rest of the United States. I focus on two key economic indicators: total population change since 1969 and net domestic migration measured using earning capacity instead of population. I find that the Heartland’s metropolitan areas are significantly lagging the entire rest of the nation in working-age population and working-age earning capacity growth. I also find that the Heartland’s non-metropolitan areas are in absolute decline when viewed through the lens of working-age population and earning capacity. Unlike the metropolitan performance, however, there is nothing exceptional about the non-metropolitan decline. My …

The Mere Presence Of A Cell Phone May Be Distracting, Samantha Sanchez

2020 Symposium Posters

Research demonstrates that the frequent usage of cellphones is disruptive and leads to reduced efficiency while multitasking and also suggested that the sheer existence of a mobile phone might be as equally disruptive and have adverse social contact implications. Previous research (Thornton, Faires, Robbins, and Rollins 2014, Exp 2) reported that students in a classroom setting performed poorer on a series of cognitive tasks when their cell phones were on their desk than when they were not. This study’s hypothesis: In this direct replication study, it was predicted that students whose cell phones were on their desk would perform poorer …

Darfurians In The Diaspora: Perceptions Of The Conflict In Darfur, Sudan’S Past And The Future Of Darfur Under International Response, Abdulrazik Mi Mohamed

2020 Symposium Posters

A strong scholarly focus in Sudanese studies has come to life corresponding to the increased interest in Sudan’s past, present conflicts, and a long period of war throughout various regions. Many scholars have extensively explored the war and genocide in Darfur and made a plentiful contribution to the literature on otherwise limited Sudanese studies. The focus of this research is the genocide in Darfur and the international response. First, this study will examine three hypotheses drawn from political science literature in Sudanese studies with special analysis of Alex de Waal’s center-periphery hypothesis in Sudan (2007), assessing how the government of …

Gender Differences In Confidence In Jury Decision Making, Rachel Silverthorn

2020 Symposium Posters

Men tend to be more overconfident than women in settings typically perceived as masculine (Lichtenstein et al, 1982; as cited in Baldiga, 2014). Women are also more likely to defer to men in mixed-sex group situations than men are to women (Hopcroft, 2009) Deference is correlated with women having lower self-esteem and lower confidence than men, both beginning to show around puberty. In same sex situations, deference is related to social ranking and physical features, but in mixed-sex situations it tends to be sex-based. Propp (1995) found that in mixed-sex groups men tend to verbally contribute more than women, whereas …

Understanding Prisoner Reentry: Public Perceptions Of Reentry Barriers Among College Students, Theresa D. Lee

2020 Symposium Posters

The United States has experienced an enormous rise and fall in crime rates, while incarceration rates have continued to soar. One of the many pressing concerns about the era of mass incarceration, especially in times where decriminalization of drug offenses occurs, communities are faced with increases in returning inmates and resources needed for successful reentry. This study is focused on community perceptions of college students toward barriers faced regarding incarceration, prisoner reentry, and improving recidivism rates in communities. Qualitative data are collected from interviews and focus groups conducted in an Inland Northwest community, to shed light on the community's perception …

Towards An Experimental Testbed To Study Cyber Worm Behaviors In Large Scale Networks, Harish Kunta, Bhavya Induri, Anu G. Bourgeois, David Maimon, Ashwin Ashok

EBCS Presentations

A worm is a malicious agent that propagates across networks of devices creating negative impacts on the devices it is able to reach and infect. Currently, there is very limited information in cybersecurity research regarding worm behavior across real networks of devices, particularly in large scale networks (e.g. campus networks, office networks, IoT etc.). This paper positions an experimental testbed that can be used for studying worm behaviors in large scale networks. In particular, this research aims to setup an infrastructure to empirically study worm generation, propagation, attacks, policies and antidote (intervention) mechanisms through a unified experimental testbed. As a …

Markus Lampe And Paul Sharp. A Land Of Milk And Butter: How Elites Created The Modern Danish Dairy Industry, J. R. Christianson

The Bridge

In her Copenhagen apartment, she had a gray stoneware jug decorated with a verse in blue letters: Før sled de bønder rent forbandet, nu er de herrerne i landet – “They used to slave with little say / But farmers rule the land today.” My wife’s grandmother had come to Copenhagen from Jutland as a pretty sixteen-year-old on the eve of the First World War, leaving behind her deep rural roots to become a city woman. The legend on her jug came true in 1901, when the farmers’ party (Venstre) took control of the Rigsdag and forced King Christian X …

Customer And Employee Social Media Comments/Feedback And Stock Purchasing Decisions Enhanced By Sentiment Analysis, Drew Mikel Hall

Walden Dissertations and Doctoral Studies

The U.S. Securities and Exchange Commission (SEC) warns professional investors that sentiment analysis tools may lead to impulsive investment decision-making. This warning comes despite evidence showing that aided social sentiment investment decision tools can increase accurate investment decision-making by 18%. Using Fama's theory of efficient market hypothesis, the purpose of this quantitative correlational study was to examine whether customer Twitter comments and employee Glassdoor feedback sentiment predicted successful investing decisions measured by business stock prices. Two thousand records from 3 archival U.S. public NASDAQ 100 datasets from March 28, 2016, to June 15, 2016 (79 days) of 53 companies with …

Association Between Maoa U Vntr Genetic Polymorphism And Aggression, Gender, And Race In Adolescents, Almaz Adair Johnson

Walden Dissertations and Doctoral Studies

A genetic polymorphism found in the upstream region of the monoamine oxidase A (MAOA) gene upstream variable number tandem repeat (u VNTR) has been shown to have an influence on aggression with mixed results. The purpose of this quantitative study was to examine the association between the u VNTR genetic polymorphism of the MAOA gene and aggression in an adolescent population 13–18 years of age. The conceptual framework was based on the biosocial model of antisocial behavior that indicates genes can influence aggressive behaviors with or without environmental influences. Data (N = 2506) from the National Longitudinal Adolescents and Adult …

Electronic Media Use And Dating Aggression Among Young Adult College Students, Christy Bazemore

Walden Dissertations and Doctoral Studies

Electronic media are popular for communication among adults ages 18 to 25. However, electronic media may also be used as tools for dating aggression, such as intimidation, insult, control, or abuse. The purpose of this quantitative casual-comparative study was to examine whether adult attachment styles predict electronically-mediated dating aggression. Adult attachment style theory provided the framework for the study. Survey data were collected from 300 first-year college students ages 18 to 25. The independent variable was students’ attachment style as measured by the Experiences of Close Relationships Scale–Revised. Dependent variables were operationalized using the Partner Electronic Aggression Questionnaire, the Situational …

Pupil Dilation Is Sensitive To Semantic Ambiguity And Acoustic Degradation, Mason Kadem, Björn Herrmann, Jennifer M. Rodd, Ingrid S. Johnsrude

Brain and Mind Institute Researchers' Publications

© The Author(s) 2020. Speech comprehension is challenged by background noise, acoustic interference, and linguistic factors, such as the presence of words with more than one meaning (homonyms and homophones). Previous work suggests that homophony in spoken language increases cognitive demand. Here, we measured pupil dilation—a physiological index of cognitive demand—while listeners heard high-ambiguity sentences, containing words with more than one meaning, or well-matched low-ambiguity sentences without ambiguous words. This semantic-ambiguity manipulation was crossed with an acoustic manipulation in two experiments. In Experiment 1, sentences were masked with 30-talker babble at 0 and +6 dB signal-to-noise ratio (SNR), and in …

From Neoliberalism To Socialism: Reimagining Socialism In Africa, Kiiru Gichuru

Dissertations and Theses

Abstract. For many scholars, pundits, policy makers, and citizens alike, Africa’s persistent maldevelopment has continued to defy the usual International Monetary Fund (IMF), World Bank, and foreign aid prescriptions that are, at times, peddled as silver bullets to the African conundrum. Beginning in the late 1970s, loans from the IMF and World Bank required African governments to implement certain conditions that were supposed to address public sector mismanagement, illiberal trade policies, low foreign investment, and state development. These austerity measures were designed to usher in an era of financial growth that would enable Africa to join the ranks of developed …

Does Overweight/Obesity Moderate The Association Between Adhd And Internalizing Difficulties In Young Adults?, Breanna Badripersaud

Dissertations and Theses

This study’s objective was to investigate if ADHD symptoms and BMI are associated with internalizing impairments of depression, anxiety, stress and lower self-esteem in college students. It was predicted that higher ADHD symptoms would be associated with elevated depression, anxiety, stress, and low self-esteem, especially if BMI fell in the overweight/obese range. Undergraduate students [N= 580; Mean (SD) age= 20.7 (3.10)] from an urban campus completed an online survey comprising self-report measures of demographics, height/weight, attention and hyperactivity/impulsivity (Barkley Deficits Executive Functioning Scale ADHD- Executive Function Index), depression, anxiety, stress (all using the Depression Anxiety and Stress Scale) and self- …

The Battle For The Battle Of Adwa: Collective Identity And Nation-Building, Joseph A. Steward

Dissertations and Theses

Abstract

On March 1^st, 1896, an Ethiopian army lead by Emperor Menelik II dealt a shocking defeat to the invading Italian forces in the Battle of Adwa. In victory, Menelik was able to exert his authority over a vast territory which included both the historical, ancient kingdoms of the northern and central parts of Ethiopia, and also the vast, resource-rich territories in the west and south which he had earlier conquered. The egalitarian nature of the victory united the various peoples of Ethiopia against a common enemy, giving Menelik the opportunity to create a new Ethiopian nation.

Compressive Behaviour Of Slender Frp-Confined Concrete-Encased Cross-Shaped Steel Columns, Le Huang, Tao Yu, Zhen-Yu Wang, Shi-Shun Zhang

Faculty of Engineering and Information Sciences - Papers: Part A

Fibre-reinforced polymer (FRP)-confined concrete-encased cross-shaped steel columns (FCCSCs) consist of a square FRP outer tube with round corners, a cross-shaped inner steel section and concrete filled in the between. The unique configuration of FCCSCs ensures that the concrete in the columns is well confined despite the square column shape, as demonstrated by the relevant existing research. The existing work on FCCSCs, however, has been limited to the behavior of short FCCSCs under axial compression. With their optimal configuration, the use of FCCSCs means that considerably reduced section dimensions may be adopted for the same load demand, leading to relatively slender …

Circular Hybrid Double-Skin Tubular Columns With A Stiffener-Reinforced Steel Inner Tube And A Large-Rupture-Strain Frp Outer Tube: Compressive Behavior, Le Huang, S S. Zhang, Tao Yu, K Peng

Faculty of Engineering and Information Sciences - Papers: Part B

A typical fiber-reinforced polymer (FRP)-concrete-steel double-skin tubular column (DSTC) consists of an FRP outer tube, a hollow steel inner tube and an annular concrete in-fill in between. The existing studies on DSTCs in the past decade have generally confirmed the good structural performance of such column form, while it is worth noting that the possible in-ward buckling of the steel tubes in DSTCs is still a problem to be addressed, especially when DSTCs are subjected to large axial deformation. Against this background, a variation form of DSTCs called R-DSTCs has been recently developed by the authors. An R-DSTC is a …

Acute Exercise On Memory Function: Open Vs. Closed Skilled Exercise, Justin Cantrelle, Grace Burnett, Paul D. Loprinzi

Faculty and Student Publications

© 2020 The Author(s). Background: Previous studies suggest that acute exercise may improve memory function. Few studies, however, have investigated the differential effect of the acute exercise movement patterns on memory. Such an effect is plausible, as research demonstrates that open-skilled exercise (e.g., racquetball) may have a greater effect on memory-related neurotrophins (e.g., brain-derived neurotrophic factors) when compared to closed-skilled exercise (e.g. treadmill exercise). A key distinction between open- and closed-skilled exercise is that open-skilled exercises are those that require an individual to react in a dynamic way to a changing, unpredictable environment. Our aim in this study was to …

Developmental Care In The Nicu: Best Practices For Preterm Infants, Expectations Of Healthcare Providers, And Impact On Parents And Families, Alicia Burrows

Honors Theses

Infants born prematurely experience a variety of medical complications, which can impair their growth and development. These complications can result in permanent disabilities and medical conditions that could necessitate a lifetime of medical treatment. Neonatal Intensive Care Units (NICUs) offer specialty units for infants born prematurely to receive excellent medical care to help them survive after being delivered at as soon as 23 weeks of gestation. A complementary form of care offered in some NICUs is developmental care, which focuses specifically on modifying the neonate’s physical environment to ensure proper growth and development. As developmental care is a relatively new …

Postnatal Bonding And Barriers: A Literature Review On Helping Secure Mother-Infant Attachment, Ivory C. Butler

Selected Undergraduate Works

The purpose of this literature review is to explore obstacles that interfere with mother-infant attachment, and what can be done to overcome these barriers. Poor mother-infant attachment can lead to strained relationships in adulthood, the worsening of pre-existing mental health issues in mothers, and a myriad of negative side effects in children, impaired social and emotional health among them. This paper examines peer-reviewed articles on obstacles to mother-infant bonding and proposes potential solutions. Methods that were found to enhance attachment include maximizing skin to skin contact, treating postpartum pathology, and reducing emotional distress in pregnancy and labor.

Personality Factors That Influence Truthfulness And Deception, Khrista E. Neville, Jonathan S. Gore, Adam Lawson

Kentucky Journal of Undergraduate Scholarship

Identifying personality traits that coincide with everyday deception is crucial to understanding how individual differences relate to antisocial tendencies. The current study tested the hypothesis that sensation seeking and psychopathy can predict everyday deception. Seventy-nine undergraduate students participated in an online study to assess these personality traits. A linear regression analysis found disinhibition psychopathy to be a strong predictor of everyday deception, with impulsive sensation seeking as the only other significant predictor.

Self-Efficacy Of Older Homeless African American Men, Renee Carnithia Harvin

Walden Dissertations and Doctoral Studies

Older adults in the United States without permanent housing are witnessed living in shelters, cars, and on street corners in many urban centers and older adults now make up a third of the homeless population. There are stressors that may precede, or may result in homelessness, which may also affect older (i.e., age 50 or above) homeless adults' abilities to maintain their self-efficacy, a key to their self- management. This study further explored the lived experiences of self-efficacy among older homeless African American men. A descriptive phenomenological design and individual semi-structured interviews of 10 African American homeless men, aged 50 …

The Values Influencing Assistant Principals' Decisions To Utilize School Resource Officers, Tracy Yvette Thompson

Walden Dissertations and Doctoral Studies

School administrators use control and maintenance to create a safe learning environment for students in the United States public schools. However, when school resource officers (SROs) within U.S. schools are assigned authority over disciplinary procedures certain students become negatively impacted. Substantial research has been conducted regarding the impact and roles of SROs, but very few studies explored the opinions of assistant principals (APs), the individuals typically responsible for the enforcement of school discipline. In this study, a qualitative interpretative design was used to explore what values and beliefs guide APs in their decisions to involve SROs in school disciplinary procedures. …

Work Adjustment And Family Caregiver Engagement In The Healthcare Transaction, Cynthia Uecker

Walden Dissertations and Doctoral Studies

Unpaid family caregivers in the U.S. now exceed 40 million people, and the question of how to effectively support the family caregiver is now decades old. Healthcare’s dominant perspective is reasonable because healthcare sees the family caregiver in the healthcare transaction. The research consistently reports caregivers cite lack of information and training as a primary reason for feeling the healthcare provider is non-supportive. This qualitative phenomenological study employed semi-structured interviews to explore whether non-supportive might represent a disconnect between caregiver and the healthcare provider purposes with respect to the caregiver role. The theory of work adjustment provides context for considering …
