Encouraging Energy Efficiancy: Pricing, Education, And Framing, Carrie A. Gill

Open Access Dissertations

The US residential sector consumed over 20 quadrillion Btu of energy in 2015, costing households billions of dollars in energy bills in addition to negative environmental and health externalities from conventional energy generation. Reducing energy consumption and promoting energy efficiency are critical for controlling costs, minimizing negative environmental impacts, and ensuring security of energy supply. Regulators and policy makers rely on a suite of strategies to promote energy efficiency and conservation. These strategies vary in degree of control over individual freedom of choice, effectiveness and impact, and political and practical feasibility. In this dissertation, I investigate the effects of three …

Exploring Ways To Enhance Teens' Participation In Social Media Interventions: A Formative Research Study, Hailee K. Dunn

Open Access Dissertations

Social networking sites (SNSs) now serve as a primary form of socialization for adolescents. A growing body of research indicates that permissive drinking norms exist on online just as they do offline increasing teens’ risk for underage drinking and other risk behaviors. However, limited research exists on how to address this growing public health problem. The purpose of the present study was to conduct a formative investigation on how to create substance prevention interventions that address adolescents’ exposure to normative displays of substance use on SNSs. Thirty-three adolescents in grades nine through twelve were recruited from various school- and community-based …

Investigating The Influence Of Word Properties On Vocabulary Outcomes Of At-Risk Kindergarteners, Chelsea A. Tucker

Open Access Dissertations

Direct and early vocabulary instruction is particularly important for children with low levels of vocabulary knowledge as they are at risk for later reading difficulties (Biemiller & Slonim, 2001). It is recommended that, through direct and systematic instruction, these children be exposed to and learn what Beck, McKeown, and Kucan (2013) regard as Tier 2 vocabulary words, a subset of approximately 7,000 word families. Given that the words in this grouping differ widely across various word properties yet are taught using relatively fixed strategies, research inquiry surrounding word difficulty is warranted. Within the context of a Kindergarten vocabulary intervention study, …

Extending Ttm-Based Quantitative Predictions To Hiv Prevention Among Msm, Bing Chen

Open Access Dissertations

The purpose of this study was to extend the Testing Theory-based Quantitative Predictions approach (TTQP) using the transtheoretical model of behavior change (TTM) to condom use behavior in a sample of men who have sex with men (MSM). The TTQP approach employs the theory to generate effect size predictions, then the observed effect sizes can be calculated and compared to the predicted effect sizes.

The effect size predictions in this study were made: 1) based on the omega squared reported in previous TTQP studies of other health behavior changes (e.g., smoking cessation); 2) based on theoretical considerations; and 3) calculated …

Doorways To Being: Modernism And 'Lived' Architectures, Amy A. Foley

Open Access Dissertations

Situated in recent scholarship on interiors and architecture in modernist fiction, "Doorways to Being" explores ways in which the modernist novel proposes a phenomenological engagement with the material environment, specifically the body in relation to transitional architectures. The study of thresholds in select modern fiction seeks to answer the essential question of how and why we move in the constructed world from the perspective of phenomenology and cultural studies. This comparative and interdisciplinary dissertation demonstrates how modernist fiction reestablishes the primacy of the sensed physical world in the spirit of Maurice Merleau-Ponty. The introduction theorizes the threshold or doorway as …

Managing Legislative And Local Budget Cuts: Strategies Used By Community Colleges, Brian Anthony Stokes

Open Access Dissertations

Research Problem Statement: This dissertation examined strategies that community colleges have been using to manage legislative and local budget cuts since the downturn of the economy in 2008. The study examined three key research questions: (1) What types of non-traditional revenue sources have community colleges turned to since the 2008 economic crisis?, (2) Which strategy has been the most effective in securing different non-traditional revenue sources?, and (3) What institutional characteristics (i.e., diversity, size, location, and longevity of president) are associated with the success in securing non-traditional revenue sources? Methodology: The population of the current study is 986 public, not-for-profit, …

Student Engagement: Factors Affecting The Academic Performance And Persistence Of Hispanic Women In Stem, Maria E. Vaca

Open Access Dissertations

Hispanics are poised to change the U.S. demographic landscape and account for one-third of the national population in the next forty years (U.S. Census Bureau, 2012). Yet, presently Hispanic students are the most underrepresented ethnic group in higher education with the lowest college completion rates the country (U.S. Department of Education, National Center for Education Statistics, 2015b). Furthermore, Hispanic women are reported to attain only 3% of all STEM bachelor’s degrees nationally (U.S. Department of Education, National Center for Education Statistics, 2015a). The purpose of this study was to examine student engagement as a factor that predicts academic performance and …

Surveys on motivation and mood provided the social-psychological data. A survey on classroom environment provided the contextual data. Participants created digital compositions using GarageBand on classroom computers to serve as the creative task. The compositions were rated for originality, craftsmanship, and aesthetic appeal using the Consensual Assessment Technique, which provided the …

Interactions Between Stress-Induced Inflammation, Glycogen Synthase Kinase 3 (Gsk3), And Depression, Yuyan Cheng

Open Access Dissertations

Major depressive disorder is a prevalent disease that is inadequately treated with available interventions, and recovery is difficult, particularly in patients refractory to antidepressant treatments. Studying the learned helplessness depression model in mice, we examined mechanisms regulating its initiation and regulating its reversibility. Stress increases susceptibility to depression in patients and rodent models, and depression is associated with aberrant activation of inflammation. We found multiple inflammatory cytokines were increased in mouse plasma and hippocampus after a paradigm of inescapable foot shock stress that causes learned helplessness. A 24 hr prior pre-conditioning stress accelerated the rate of stress-induced plasma and hippocampal …

Management Of Preoperative Distress By Anesthesia Providers In Toddlers And Preschoolers, Rossana Bizzio- Knott

Open Access Dissertations

The period of time associated with a child’s preparation for surgery and induction of general anesthesia is one of the most stressful events a child can experience. It is estimated that 40-60% of children experience preoperative anxiety before induction of anesthesia. Toddlers and preschoolers’ cognitive limitations, lack of self-control, high level of dependency on adults, and their limited understanding of the healthcare process make them prone to experience distress and excessive anxiety during the preoperative period. This inability to fully comprehend or manage the hospitalization experience leads to preoperative distress. Children’s preoperative distress has also been linked to ineffective coping …

Who’S Shaping Who’S Opinions? Estimating The Degree Of Influence Exerted By Each Contact In A Social Network, Luis Eduardo Castro Abril

Open Access Dissertations

It is important in domains such as organizational behavior, politics, marketing, sociology, psychology, engineering, and economics to study how people that belong to a network form their opinions on a specific topic, how these opinions evolve, and how a consensus is reached. Researchers have mainly focused on estimating hidden opinions, identifying opinion trends, opinion leaders, consensus points, and the impact of the structure of the network on consensus. This dissertation proposes a model that (a) enables the tracking of the opinions of every member of a network, and (b) helps identifying who is influencing who’s opinions and to what degree …

Essays On Value Creation In Online Marketplaces, Warut Khern-Am-Nuai

Open Access Dissertations

This dissertation consists of three essays that study the transformative impact of new information technologies under three specific contexts using both empirical and theoretical approaches. Chapter 2 examines the online review system, which is the new type of information technology that replaces the traditional word-of-mouth communication. Particularly, we study the practice of the platform owner that uses monetary incentives to attract reviewers. The research problem is important as firms, which seek to strengthen their online review platforms, have considered various forms of incentives, including extrinsic rewards, to encourage users to write reviews. We encountered a natural experiment design where one …

Language, Culture, And Identity Negotiation: Perspectives Of Adolescent Japanese Sojourner Students In The Midwest, Usa, Reiko Akiyama

Open Access Dissertations

This qualitative research highlights the voices and lived experiences of adolescent Japanese sojourner students and their mothers residing in the Midwest. The central goals of this research are to understand what adolescent Japanese sojourner students’ school experiences in the U.S. are like—particularly in areas with small Japanese populations—and how their experiences in the U.S. shape their current identities as cultural and linguistic minority students. This research also aims to learn how the students’ sojourning experiences influenced their mindsets as future returnee students. I conducted an in-depth case study with a phenomenographic approach as the theoretical framework to deeply investigate the …

The remaining three essays (Chapters 3-5) each address an extension or application of choice experiment and/or BWS methodology focused on credence attributes of meat products. Two online surveys were used …

Authentic Science In Education: Studies In Course-Based Research At The United States Military Academy, Anthony M. Chase

Open Access Dissertations

This dissertation consists of two studies at the United States Military Academy. Both studies involve the use of Course-based Undergraduate Research Experiences (CUREs). These experiences give students the ability to engage in undergraduate research at an early point in their academic career by replacing traditional laboratory activities with semester-long research projects. Both studies show an implementation of this type of instruction from the Center for Authentic Science Practice in Education (CASPiE). Study 1 shows the specific method of implementation at the military academy and explores learning-based outcomes. Primarily the outcome of critical thinking is demonstrated. Critical thinking is a construct …

Teoria De La Mente Y Sociedad En La Narrativa Policiaca De Lorenzo Silva Y Francisco Garcia Pavon: Estereotipos, Roles De Genero Y Minorias, Jesus Castro Gorfti

Open Access Dissertations

Spanish:

The purpose of this study is to utilize certain aspects of cognitive psychology as a framework to analyze the police procedural novels of two Spanish authors: Francisco García Pavón and Lorenzo Silva. Specifically, we will focus on two main aspects of the mind studied by the cognitive sciences: Theory of Mind and metarepresentations. Theory of Mind (ToM) refers to the capacity that human beings have to attribute mental states to other humans, as well as oneself, based on their bodily and facial gestures. The concept of metarepresentation refers to the ability of humans to keep track of who said …

The Association Between Tolerance For Ambiguity And Fear Of Negative Evaluation: A Study Of Engineering Technology Capstone Courses, Sergey I. Dubikovsky

Open Access Dissertations

For many students in engineering and engineering technology programs in the US, senior capstone design courses require students to form a team, define a problem, and find a feasible technical solution to address this problem. Students must integrate the knowledge and skills acquired during their studies at the college or university level. These truly integrative design activities do not have a single “correct” solution. Instead, there is an array of solutions, many of which could be used to achieve the final result. This ambiguity can cause students to experience anxiety during the projects.

This study examined the main topics: • …

How Training Set And Prior Knowledge Affect Preschoolers' Perception Of Quantity And Early Number Learning, Arum Han

Open Access Dissertations

This dissertation examines how training on the iPad can improve children’s quantity recognition, and whether different types of training might be warranted for children with different levels of experience. Study 1 tested the effects of multiple exemplar training (3 cars / 3 apples / 3 ducks, etc.) versus single exemplar training (3 cars / 3 cars / 3 cars, etc.) in recognizing quantities. For children just learning to recognize quantities (0-2 knowers), training with multiple exemplars was most effective for quantities three and four. For 3-6 knower children, single exemplar training was most effective for learning quantities five and six. …

Finding The Ghost With The Machine: Breaking Through The Assessment Center Validity Ceiling By Exploring Decisional Processes Using New Sources Of Behavioral Data Within Virtual Assessments, Brett W. Guidry

Open Access Dissertations

Decades of assessment center (AC) research has resulted in an inevitable “validity ceiling” whereby increasing the validity of the AC method is becoming increasingly difficult. To overcome this challenge, new avenues for collecting and evaluating AC participant behaviors must be explored, with a particular focus on overcoming the inherent limitations of human observation—a hallmark of the AC method. This study examines detailed logs of AC participant behaviors captured automatically and unobtrusively during a computer-based simulation assessment. Using a decision making framework, basic characteristics of the new behavioral data are tested against existing theories of decisional efficacy. The construct-related validity of …

Bad Girls In Corsets: Women And The Transgressive Body In The Nineteenth Century, Colleen Warwick Green

Open Access Dissertations

Women, and their bodies, posed an increasing anxiety for Victorian society. Culturally and outwardly, the Victorian era strove to maintain a level of decorum that, increasingly, the nineteenth-century woman were, rebelling against. The urge for women to break through social barriers and constraints binding them to the century created a divergence in thought from the traditional mores of the past, in turn affecting the ways in which womens’ bodies were portrayed, displayed and manipulated by the authors and artists of the century.

As women entered actively entered into spaces once closed to them, they furthered the rift of uncertainty and …

Perceval's Sister And Juliet Capulet As Disruptive Guides In Spiritual Quests, Joanna Benskin

Open Access Dissertations

Perceval’s sister in Sir Thomas Malory’s Le Morte Darthur and Juliet in William Shakespeare’s Romeo and Juliet act as disruptive guides in spiritual quests by contradicting the expectations placed on them as women characters.

Though women are banned from the quest for the Holy Grail, Perceval’s sister accompanies the Grail knights as an authoritative spiritual guide and a symbol of the Eucharist. Previous critics have not recognized Perceval’s sister as a fundamental disruption to the systemic misogyny of the Morte or her Eucharistic significance. She challenges both the chivalric misogyny that sees her as an object of rescue and the …

Exploring The Cause Of Injury Or Death In Grain Entrapment, Engulfment And Extrication, Salah F. Issa

Open Access Dissertations

Grain entrapments and engulfments are one of most common hazards associated with grain storage facilities. Since the 1970’s over 1,880 incidents have been documented in agricultural confined spaces of which 65% of all recorded incidents were grain entrapments and engulfments. There have been several studies conducted on the contributing factors behind these incidents; however, there have been very few attempts to understand the environmental, physiological or psychological factors the victims experience while entrapped, engulfed, or extricated. This includes understanding how secondary injuries are caused by grain or during extrication by first responders. The research effort was divided into three segments. …

The Application Of Natural Language Processing To Open Source Intelligence For Ontology Development In The Advanced Persistent Threat Domain, Corey T. Holzer

Open Access Dissertations

Over the past decade, the Advanced Persistent Threat (APT) has risen to forefront of cybersecurity threats. APTs are a major contributor to the billions of dollars lost by corporations around the world annually. The threat is significant enough that the Navy Cyber Power 2020 plan identified them as a “must mitigate” threat in order to ensure the security of its warfighting network.

Reports, white papers, and various other open source materials offer a plethora of information to cybersecurity professionals regarding these APT attacks and the organizations behind them but mining and correlating information out of these various sources needs the …

College Students' Suicidal Ideation: Testing The Predictions Of The Existential - Constructivist Theory Of Suicide, Jennifer Danielle Lockman

Open Access Dissertations

Suicide is the second leading cause of death in the college student population (Schwartz, 2006), and empirically supported theories for understanding suicide among college students are lacking (Lester, 1989; Prinstein, 2008; Rogers & Benson, 2013). Although not yet examined empirically, Rogers (2001) proposed an Existential - Constructivist Theory of Suicide (ECTS), in which existential distress and the inability to reconstruct meaning from adverse life events contribute to suicidal ideation. ECTS includes both interpersonal and intrapersonal drivers of suicidal ideation, and for this reason, may better explain suicidal ideation in college students than existing theoretical models. Existing research focuses on Joiner’s …

Poetry Matters: Radical Politics In Postmodern American Poetry, Christopher J. Padgett

Open Access Dissertations

Directly or indirectly, poetry produced in the postmodern era is implicated in the politics of the time. Postmodern American poetry, then, is not reducible to a single poetic mode or to a specific set of stylistic features. In other words, a more comprehensive understanding of postmodern American poetry can be made by employing a flexible version of Raymond Williams’ notion of uneven development, a theory that insists on the synchronic existence of dominant, residual, and emergent cultural elements. As the stylistically and politically diverse work of the six poets—Susan Howe, Robert Grenier, Gary Snyder, A.R. Ammons, Sherman Alexie, and Kenneth …

State Judicial Selection Methods As Public Policy: The Missouri Plan, James A. Gleason

Open Access Dissertations

State judiciaries are foundational institutions of governance in the United States. They are coequal, policy-making branches of government whose members, along with the legislative and executive branches, are constitutionally authorized and empowered in all fifty American states. Extant research on judicial selection in the American states provides neither a comprehensive theory of why states choose their particular judicial selection method nor a comprehensive empirical assessment of this important question. This research seeks to fill this lacuna by increasing understanding of American state courts through the formulation of a theory of state judicial selection, a short but comprehensive history of state …

Race, Class And Gender In Engineering Education: A Quantitative Investigation Of First Year Enrollment, Canek Moises Luna Phillips

Open Access Dissertations

Research explanations for the disparity across both race and gender in engineering education has typically relied on a deficit model, whereby women and people of color lack the requisite knowledge or psychological characteristics that Whites and men have to become engineers in sufficient numbers. Instead of using a deficit model approach to explain gender and race disparity, in the three studies conducted for this dissertation, I approach gender and race disparity as the result of processes of segregation linked to the historic and on-going perpetuation of systemic sources of oppression in the United States. In the first study, I investigate …

A Phenomenological Inquiry Into Sacred Time In Hinduism, Netty Provost

Open Access Dissertations

In this work, I examine the nature of sacred time in religious experience. Applying the methodology of phenomenology of religion, I inspect the ways in which human beings experience sacred time in Hinduism and present an argument against Mircea Eliade’s understanding of the nature of sacred time in Hinduism. Eliade asserted that all sacred time in Hinduism is fundamentally circular in nature and that the experience of sacred time is an experience of the original act of creation being made consciously present to the individual.

I will scrutinize Eliade’s arguments on two fronts. Firstly, I argue against Eliade’s claim that …

A New Approach To Modeling Aviation Accidents, Arjun Harsha Rao

Open Access Dissertations

General Aviation (GA) is a catchall term for all aircraft operations in the US that are not categorized as commercial operations or military flights. GA aircraft account for almost 97% of the US civil aviation fleet. Unfortunately, GA flights have a much higher fatal accident rate than commercial operations. Recent estimates by the Federal Aviation Administration (FAA) showed that the GA fatal accident rate has remained relatively unchanged between 2010 and 2015, with 1566 fatal accidents accounting for 2650 fatalities. Several research efforts have been directed towards betters understanding the causes of GA accidents. Many of these efforts use National …
