Three Essays In Economics, James R. Bland

Open Access Dissertations

How Many Games Are We Playing: An Experimental Analysis of Choice Bracketing in Games

A subject brackets two decisions if she "choose[s] an option in each case without full regard to the other" Rabin (2009). Although in most situations such behavior is unlikely to be optimal, it is well documented in experiments where subjects make decisions in the absence of strategic considerations. This paper uses an economic experiment to investigate whether subjects also bracket their decisions in games. Subjects played two Volunteer's Dilemmas at the same time, with the payoffs from both games added to their earnings. In a lottery …

Data Mining Twitter For Cancer, Diabetes, And Asthma Insights, Kimberly Chulis

Open Access Dissertations

Twitter may be a data resource to support healthcare research. Literature is still limited related to the potential of Twitter data as it relates to healthcare. The purpose of this study was to contrast the processes by which a large collection of unstructured disease-related tweets could be converted into structured data to be further analyzed. This was done with the objective of gaining insights into the content and behavioral patterns associated with disease-specific communications on Twitter. Twelve months of Twitter data related to cancer, diabetes, and asthma were collected to form a baseline dataset containing over 34 million tweets. As …

Essays On Health Insurance, Amanda C. Cook

Open Access Dissertations

Uninsured individuals receive fewer health care services for at least three reasons: higher prices, responsibility for the entire bill, and potential provider reductions for concern of non-payment. This study isolates differences in service levels between insured and uninsured individuals that are attributed to different effective prices; the uninsured pay the bill without a contribution from an insurance company. I capitalize on Maryland's highly regulated health care system, where prices are set by the state, are uniform across all patients, and hospitals are compensated for free care and bad debt, to isolate the difference in quantity demanded by the uninsured. While …

Facebook Engagement On College Students' Interpersonal And Intrapersonal Functioning, Scott S. Deatherage

Open Access Dissertations

In recent years college students have incorporated social-networking sites, and more specifically Facebook, into their daily lives. Facebook has received empirical attention; attention focused on what students are doing on Facebook, who its users are, and, more recently, why students access Facebook. However, researchers who have assessed motivations for accessing Facebook have emphasized how motivations are associated with certain activities, and have not simultaneously and directly examined how activities and motivations are associated with both maladaptive and adaptive factors of students’ interpersonal and intrapersonal functioning. The purpose of the present study was to examine how Facebook engagement is associated with …

The Effects Of Including Almonds In An Energy-Restricted Diet On Weight, Body Composition, Visceral Adipose Tissue, Blood Pressure And Cognitive Function, Jaapna Dhillon

Open Access Dissertations

Inclusion of almonds in an energy restricted diet has been reported to enhance or have no effect on weight loss. Their effects specifically on visceral fat stores during energy restriction have not been widely examined. Additionally, almond consumption has been associated with reduced blood pressure, but whether this is linked to or is independent of changes of body composition has not been examined. Moreover, almond consumption during energy restriction may be an effective strategy for reversing the negative effects of dieting on cognitive performance. The unique nutrient profile of almonds also has the potential to influence cognitive function post-prandially. The …

The Politics Of Town Hall Meetings: Analyzing Constituent Relations-In-Interaction, Robert J. Green

Open Access Dissertations

The politics of town meetings proposes that town hall meetings are institutions of representative democracy that present an opportunity for constituents to hold their elected representatives accountable in a public setting. Constituent relations-in-interaction glosses a complex set of interactional practices and procedures through which ensembles of participants bring town hall meetings, as structures of social interaction, into being. This study uses conversation analysis, the study of talk-in-interaction, to show that the politics of town hall meetings orients to three types of accountability: Interactional accountability, political accountability, and public accountability. The articulation of these accountability types provides a sense of overall-structural …

Help-Seeking Intention Among College Students: Cross-Cultural Study Between East Asian International Students And Domestic Students In The Unites States, Ji Yun Kang

Open Access Dissertations

The purpose of this study is to understand East Asian international student’s underutilization of counseling services (versus U.S. domestic students) by applying Theory of Reasoned Action/Planned Behavior (TRA/PB) and Ludwikowski, Vogel, and Armstrong (2009)’s stigma model to help-seeking. Participants were 146 East Asian international students and 210 domestic college students at Purdue University. AMOS 23.0 for Structural Equation Modeling was used to conduct a Latent Mean Analysis (LMA) and a multigroup analysis. The multigroup analysis results found that help-seeking intention was explained by the same hypothesized model in both groups, which was based on the TRA/PB (Ajzen, 2012) and the …

Us Strategic Retrenchment And Security-Seeking Behaviors Of The Us Allies In Northeast Asia, Seok Ryul Kang

Open Access Dissertations

This research is planned to explore how a regional state could improve its security during the time of its patron’s strategic retrenchment. It introduces a theory of a regional state’s security-promoting behaviors during the time of its patron’s retrenchment. According to this theory, it is hypothesized that there is covariation between the level of a regional state’s security concern and the scope of its domestic drives to increase societal contribution to autonomous defense posture. It also hypothesizes the existence of covariation between the level of a regional state’s security concern and the level of its commitment to the pursuit of …

Silent Dissent: The Effect Of Structural Secrecy On Professional Communication At Nasa, Charlotte N. Hyde

Open Access Dissertations

This dissertation examines the creation and legitimization of knowledge through an examination of Dr. Warner von Braun’s weekly communications with his department heads during the Apollo project. My researched is focused on an archive of memos from the Marshall Space Flight Center during the 60’s. The memos were referred to as either Monday Notes or Weekly notes. I use the terms interchangeably, but some scholars differentiate between the two and refer to the Monday Notes as the communication system that worked during the Apollo project and the weekly notes as the communication system that broke after the Apollo project. In …

State Based Financial Liberalization, Robert J. Kulzick

Open Access Dissertations

In the last 40 years, states around the globe have increased the role of markets in their financial systems. Using newly collected information on the educational backgrounds of Central Bankers, I demonstrate that the beliefs of state officials about the proper role of markets in the financial system influence the extent to which state's liberalize their financial systems. By tracing the liberalization experiences in both France and China through secondary sources, I show that bureaucrats within the state suggest reforms that conform to their neoliberal training when political leaders turn to them for solutions to what are perceived as technical …

The Role Of Experience In Processing Foreign-Accented Speech, Fernando Llanos Lucas

Open Access Dissertations

The present study examines the perceptual accommodation of the bilabial stop-consonant voicing contrast (i.e., /b/ vs. /p/), in several English- and Spanish-accented contexts, by native Spanish listeners with different degrees of experience with accented speech. In a series of four experiments, we confronted three potential mechanisms for the perceptual accommodation of foreign-accented sounds. According to the first mechanism (phonetic relaxation), listeners accommodate foreign-accented sounds by relaxing the phonetic boundary between native speech sound categories. According to the second mechanism (phonetic calibration), listeners accommodate foreign-accented sounds by adjusting the location of native perceptual boundaries according to the phonetic realization of native …

Disentangling Universal And Cultural-Specific Risks To Mental Health Among Asian Americans: A Multi-Site Longitudinal Investigation, Pan Priscilla Lui

Open Access Dissertations

Objective: Development-based intergenerational conflict related to separation-individuation is normative and similar across ethnocultural groups. Intergenerational cultural conflict related to acculturation mismatch—where intercultural contact leads parents and offspring to diverge in heritage and mainstream American values and behaviors—is specific to immigrant families. Although development-based conflict does not result in serious psychological distress or behavioral problems among healthy adolescents and emerging adults, acculturation-based conflict has been linked to maladjustment among offspring with immigrant parents in cross-sectional studies. The distinct and potentially mutually influential contributions of these types of conflict have not been evaluated as simultaneous processes unfolding during the developmentally significant transition …

Knitting Rebellion: Elizabeth Zimmermann, Identity, And Craftsmanship In Post War America, Maureen Lilly Marsh

Open Access Dissertations

At mid 20th century, hand knitting in the United States was practiced as a minor and fading chore of the domestic economy, with decreasing pattern publications in national women’s magazines, and the demise of Vogue Knitting Book by the late nineteen-sixties. By 1990, it had rebounded into major new publications in periodicals and books, new and revived artisanship practices, gallery exhibitions and major international conferences and gatherings. A driving figure in this resurgence was the knitter, writer, teacher, designer, and publisher Elizabeth Zimmermann. With her initial publication in 1955 up to her retirement in 1989, Elizabeth’s philosophy of knitting stressed …

Improving Online Food Safety Communication: The Role Of Media, Jing Ma

Open Access Dissertations

Food safety is important as foodborne illness outbreaks cause great economic and societal losses. Efforts to protect public health and reduce foodborne illness outbreaks will not be fully effective unless the resulting information is communicated to consumers.

However, food safety communications have not been particularly satisfactory (Worsfold, 2006). If food safety information were more accessible, consumers would be more likely to use it (Worsfold, 2006). In this regard, the Internet presents great possibilities for communicating food safety information to the public. But media’s role has been largely overlooked in existing literature. When the lack of research is combined with consumers’ …

Local Matters: Regulating Economic Development In Two Indiana Cities, Christopher A. Malackany

Open Access Dissertations

Since the 1970s, local governments have utilized similar redevelopment tools to counteract economic dislocations but cities often experience divergent development pathways. This project explores why these divergences occur through a comparative case study of a college town and factory town in Indiana. Qualitatively, I compile data from interviews with city officials, local government documents, and related research to address the towns’ divergent development paths. Two findings are noteworthy. First, a locality’s extant resources act as path-dependent liabilities for local growth. Second, state and federal aid greatly assists local development. Yet the defunding of these revenue streams, and a city’s reliance …

Decentering The Writing Program Archive: How Composition Instructors Save And Share Their Teaching Materials, Stacy Olivia Nall

Open Access Dissertations

This dissertation decenters the writing program archive through research on instructors’ digital archives. Artifacts of composition instruction are no longer saved to print archives alone; rather, digital technologies expand the locations where artifacts of writing pedagogy can be archived and accessed. The following archival ethnography, focused on a community engagement writing course in the Introductory Composition at Purdue (ICaP) program, finds that many digital archives of composition are hidden to outside researchers or not sustained (which are theorized as either “abandoned” or “pop-up” archives). At the same time, some pedagogical materials are publicly visible by virtue of personal web spaces …

It Is "Broken" And "Accented": Non-Native English-Speaking (Nnes) Graduate Students' Perceptions Toward Nnes Instructors' English, Hyo Jung Keira Park

Open Access Dissertations

This study investigates the perceptions of non-native English-speaking graduate students towards non-native English speaking (NNES) instructors’ accented English. Students (N=161) who were enrolled in an oral English course at Purdue University participated in a survey. Follow-up interviews were conducted with voluntary participants (N=9) to examine the perceptions of NNES graduate students towards NNES instructors in depth. The findings in the survey showed that more than one third of the participants experienced difficulty with their NNES instructors due to their limited intelligibility and restricted command of English. Furthermore, one third of the participants expressed that they would transfer to another section …

L2 Effect On Bilingual Spanish/English Encoding Of Motion Events: Does Manner Salience Transfer?, Heidi E. Parker

Open Access Dissertations

This study explores the potential effect of a second language (L2) on first language (L1) encoding of motion events. The domain of interest is MANNER and the goal is to investigate if the degree of manner salience can be restructured under the effect of a L2. Slobin (2004, 2006) proposes an expansion of Talmy’s (1985, 1991, 2000) binary typology and observes that the degree of manner saliencevaries cross-linguistically. The two languages investigated in this study, Spanish and English, are at divergent points along the cline of manner salience. In addition, Slobin (1996b) suggests dividing MANNER into tier one (T1) …

South Asian Women's Sexual Relationship Power: Examining The Role Of Sexism, Cultural Values Conflict, Discrimination, And Social Support, Chandni D. Shah

Open Access Dissertations

The lack of literature examining sexual experiences of South Asian women in dating relationships has important implications for the healthy development of long lasting romantic relationships. It is important to understand South Asian women’s relationship experiences in the context of power and sexism (interpersonal power framework; Pulerwitz, Gortmaker, & DeJong, 2000) and the role of specific sociopolitical factors (e.g., discrimination). Understanding South Asian women’s experiences of power in a sociopolitical context will help professionals when working with them to develop healthier sexual relationships through therapy outreach, and community programming. I used a correlational, quantitative study to examine the associations between …

Emerging Genres, Dangerous Classifications: The Kairos Of Digital Composing Policy, Ellery Sills

Open Access Dissertations

Emerging Genres, Dangerous Classifications: The Kairos of Digital Composing Policy argues that writing policy infrastructure plays a significant (if often invisible) role in affording emerging digital genres in rhetoric and composition. Within the last few decades, the accelerating transformations and instabilities of emerging genres have posed a challenge for contemporary writing programs, which demonstrate a persistent wariness over incorporating digital composing into their mission. In response to this challenge, national educational associations have issued a growing number of policy statements meant to encourage a broader understanding of composing in the classroom. Curiously, relatively little scholarly attention has been paid to …

Psychosocial Factors And Mental Health Of Muslims Living In The United States, Lamise N. Shawahin

Open Access Dissertations

Muslim Americans are at risk for experiencing systematic and interpersonal acts of discrimination (Rippy & Newman, 2006). Such experiences of discrimination can lead to the development of depressive symptoms. Thus, it is critical to understand factors that may influence the relationship between experiencing discrimination and developing depressive symptoms. The purpose of the present study was to examine the relationship between psychosocial adversities (i.e., perceived discrimination), psychosocial resources (i.e., coping strategies, religious community support) and depressive symptoms. Hypotheses regarding both the relationships among the variables, as well as the mediating role psychosocial resources play in the relationship between perceived discrimination and …

Facial Processing And Social Motivation In Psychopathy: An Event-Related Potential Study, Emily Dubose Sherman

Open Access Dissertations

Recent work has urged a shift in the perspective of psychopathy to focus on the interpersonal aspects of the disorder that are often overlooked in the broader literature. Conceptual and empirical overlap with an exemplar interpersonal disorder- autism spectrum disorder- lends support to viewing psychopathy as an interpersonal disorder; however, there are interpersonal dysfunctions associated with psychopathy that cannot be attributed wholly to overlap with autistic traits. The current study examined self-report measures, a lab task, and event-related potentials (ERPs) that are related to social, interpersonal functioning and motivation to help elucidate what aspects of psychopathy and ASD are overlapping …

An Analysis Of The Current Strength Of The Academic Relationship With The Aerospace Industry, James A. Stratton

Open Access Dissertations

The objective of this research was to discover which methods of technology transfer were most commonly accessed within the Indiana manufacturing sector in an effort to best serve companies in the Hoosier State. Previous work has explored the perceived importance of various academic sources, but there has not been an investigation to identify the specific preferences of industry professionals. If these preferences can be identified, university assistance programs and other academic engagement programs will be able to predict, and hopefully influence how to grow and develop the domestic manufacturing sector, ultimately strengthening the channels of knowledge transfer between academia and …

The Graphic Side Of Fear: The Effects Of Anti-Tobacco Graphic Threat Appeals, Latasha R. Swanson

Open Access Dissertations

Many public health organizations have proposed and implemented campaigns and policies involving graphic ads or warnings to deter individuals from smoking. The current study evaluated how high-cigarette dependent smokers evaluate these messages compared to low-cigarette dependent smokers using a mixed, 3 x 2 factorial design. A pilot study involving focus groups, interviews, and evaluation questionnaires (N=10) was conducted to classify graphic threat appeals and develop stimulus materials for the primary study. For the primary study, three graphic threat appeal conditions were evaluated by Amazon Mechanical Turk (MTurk) users (N=200). Findings suggested that the graphicness of the …

Risks And Health Consequences Of Forgoing, Delaying, Or Having Trouble Accessing Needed Health Care Among Medicare Beneficiaries, Angelitta M. Spells

Open Access Dissertations

Medicare provides health care coverage for approximately 93% of non-institutionalized older adults. Compared to uninsured adults, Medicare beneficiaries have greater access to needed healthcare including preventative care. However, disparities in accessing needed health care still exist among Medicare beneficiaries. Prior research has described barriers to accessing needed health care among older Medicare beneficiaries, such as transportation and health system characteristics, but little is known about prevalence, risks, or health consequences of older Medicare beneficiaries delaying, forgoing, or having trouble accessing needed health care. The three studies included in this dissertation followed a nationally representative sample of older Medicare beneficiaries to …

Reflexivity: A First Demonstration, Melissa Jane Swisher

Open Access Dissertations

Currently, the emergent relation of reflexivity after training a set of baseline relations has not been demonstrated with any animal—human or nonhuman. True reflexivity can only be demonstrated if no identity (i.e., physically matching stimulus) relations are trained. In six experiments, the emergence of reflexivity and its opposite, anti-reflexivity, were explored. Pigeons received concurrent successive matching training on two or three arbitrary tasks: AB hue-form and BC form-hue (and AC hue-hue) matching. Once they had acquired these tasks, they were tested for BB (form-form) reflexivity or BB’ (form-form) anti-reflexivity matching. Most (10 of 13) pigeons that received three arbitrary tasks …

Essays In Labor Economics And Panel Data Analysis, Evan S. Totty

Open Access Dissertations

This dissertation is composed of three independent chapters. The first chapter studies the impact of minimum wage hikes on employment of low-skill workers in the United States. The second chapter studies the lasting impact of attending a higher value-added high school on college performance. The third chapter studies the impact of stuttering on labor market outcomes.

The first chapter resolves issues in the minimum wage-employment debate by using factor model econometric methods to address concerns related to unobserved heterogeneity. Recent work has shown that the negative effects of minimum wages on employment found using traditional methods are sensitive to the …

Exploring Animacy As A Mnemonic Dimension, Joshua Edward Vanarsdall

Open Access Dissertations

There is a great deal of evidence across cognitive science that animacy, or more generally, the features that make up what it means to be a living thing, is a foundational dimension of human cognition. In perception, animates both capture attention (Pratt, Radulescu, Guo, & Abrams, 2010) and are relatively immune to change blindness (New, Cosmides, & Tooby, 2007). Developmental work places the animate-inanimate distinction as one of the first categories children learn (Opfer & Gelman, 2011). Work in neuroscience points toward a fundamental role for animacy in semantic memory (Caramazza & Mahon, 2003), and linguists have identified animacy as …

After The Honeymoon: The Obama Effect On Political Attitudes And Participation, Laurent W. Vesely

Open Access Dissertations

My dissertation takes a mixed-methods approach to investigating the possibility of a lasting Obama Effect on the political attitudes and behaviors of Obama supporters from 2008. Defining the Obama Effect as the extraordinary enthusiasm surrounding Barack Obama’s 2008 campaign, I argue that a short term Obama Effect was clearly present in 2008 based on Obama’s electoral success, fundraising prowess, and ability to inspire volunteerism, as well as on the historic nature of his candidacy. But I ask, was it a lasting effect? My quantitative analyses—built upon panel survey data from the American National Election Studies—suggest little evidence of a lasting …

Exploring Problematic Online Gaming: A Qualitative Approach, Joseph M. Waters

Open Access Dissertations

Online gaming, specifically Massively Multiplayer Online Role-Playing Games (MMORPGs), has become a very popular pastime and often is the subject of scrutiny in the literature regarding problematic play. This study aimed to develop a better understanding of problematic online gaming by recruiting and interviewing MMORPG players who potentially played at problematic levels. Ten participants (9 males, 1 female) from a Mid-Western university were screened and interviewed regarding their online gaming experiences. Consensual qualitative research was used to analyze the data. Eleven domains emerged from the data analysis: (a) antecedents to involvement in online gaming, (b) gaming activity, (c) character creation, …
