VAGABONDS AND THE VIRTUAL: IDENTITY, ECONOMICS AND ETHICS IN THE GENRE OF DIGITAL TRAVEL WRITING

While the genre of travel writing has been popular with authors and audiences over centuries, developments in new media, social media and public use genres have caused an adaptation of the genre in the digital space. This genre, as it exists, claims two antecedents: first, the traditional and literary version of the genre and second, the blogs that emerged and were popularized in the late twentieth century. In exploring the genre of digital travel writing,...

TWO ESSAYS ON SERVICE ROBOTS AND THEIR EFFECTS ON HOTEL CUSTOMER EXPERIENCE

Artificial intelligence (AI) and robotics are revolutionizing the traditional paradigm of business operations and transforming consumers’ experiences by promoting human–robot interaction in tourism and hospitality. Nonetheless, research related to customers’ experiences with robot-related services in this industry remains scant. This study thus seeks to investigate hotel customers’ experiences with service robots and how robot-based experiences shape customers’ satisfaction with hotel stays. Specifically, three research questions are addressed: (a) What are hotel customers’ primary concerns about...

Applying the Generalized Matching Equation to Penalty Kick Selection During Elite Soccer Competition

The Generalized Matching Equation (GME) has been utilized by many behavioral researchers as a model of operant choice, especially in elite sports. In this instance, the GME was used to analyze the penalty-kick selections (e.g., shoot right or shoot left) of nine elite international soccer players. The analysis of archival data from in-game decisions demonstrated the presence of matching across participants and within a naturalistic setting. Undermatching consistent with previous laboratory and non-laboratory research on...

Geochemical Behavior of Low Valence Manganese Oxides: Effects of Structural Impurity and Secondary Mineral

As the third most abundant transition metal in the Earth’s crust, manganese (Mn) is often found in various forms of (oxyhydr)oxides in the environment (hereafter, Mn-oxides). Mn-oxides possess a high sorption capacity and are a powerful oxidizer, and thus, play critical roles in regulating nutrient cycles and the speciation and distribution of trace metals and metalloids in the environment. The structure and geochemical behaviors of Mn-oxides have been extensively studied using birnessite minerals that contain...

Single-Molecule Study of β-Catenin Translocation and the Role of Custos in its Regulation

The nuclear pore complex is closely involved in the regulation and control of many cellular processes, including the movement of molecules into and out of the nucleus along with the regulation of gene transcription. It is therefore a major barrier for controlling the passage of signaling molecules into and out of the nucleus. β-catenin is one such signaling molecule, and a primary signaling molecule of the Wnt signaling pathway. How the passage of β-catenin into...

Exact Relations Satisfied by the Effective Tensors of Two-Dimensional Two-Phase Thermoelectric Composites

Thermoelectric materials have been used for cooling and heating systems for over a hundred years. Today practical applications of thermoelectric devices include cooling car seats, power generation, and refrigeration. Thermoelectric materials are special for their ability to convert temperature imbalances into electricity. Their applications can inform the discourse about the transition to renewable energy sources---something that our Earth most desperately needs. The goal of this dissertation is to describe how the effective tensors of two-dimensional...

NONLINEAR AND ULTRAFAST OPTICAL STUDIES OF INTERFACIAL PROCESSES IN PHOTOVOLTAIC NANOMATERIALS

The development of efficient solar energy conversion devices has attracted much attention. Despite the fact that progress have been achieved, a fundamental understanding examining why efficiency can be improved remains elusive. For example, dye-sensitized solar cells (DSSC) exhibit high conversion efficiency when acetonitrile is used to prepare both the working electrode and the electrolyte. However, the mechanism explaining exactly how solvent influences device performance has not yet been systematically investigated. Another prominent example is the...

MAGNESIUM DIBORIDE (MGB2) THIN FILMS ON COPPER AND SILICON FOR RADIOFREQUENCY CAVITY AND ELECTRONIC APPLICATIONS

Magnesium diboride is a known material since the 1950s. However, superconductivity in MgB2 was discovered in 2001. Soon after the discovery of superconductivity in MgB2, there was a rush to understand its complex nature of superconductivity and other properties. However, current research in MgB2 is mainly focused on applications. MgB2 possesses excellent superconducting properties such as a high transition temperature (Tc) of 39 K, a high critical current density (Jc) of ~107 A·cm-2, a high...

This study examines the literacies taught and valued by three major stakeholder groups within an innovative welfare-to-work/adult basic education (ABE) program in the northeastern United States. The program, which I call Women for Change, is examined from the perspective of the program participants (a group of eight women on TANF who are mandated to attend), program staff (four social workers affiliated with a local university and one veteran adult basic educator), and the organization that...

Resisting the Melting Pot Through Ethnic Newspapers: A Case Study of the Irish Echo

This dissertation is a case study of the Irish Echo, an Irish ethnic weekly newspaper that began publishing in New York City in 1928. The Irish ethnic community is unique because it operates within two cultural spheres: Irish society and American society. The purpose of this case study is to identify how ethnic newspaper function and how this function has changed over time. The study attempts to explain the role of the ethnic newspaper in...

Veteran Narratives and the Collective Memory of the Vietnam War

This dissertation is a comprehensive study of the content, author demographics, publishing history, and media representation of the most prominent Vietnam veteran memoirs published between 1967 and 2005. These personal narratives are important because they have affected the collective memory of the Vietnam War for decades. The primary focus of this study is an analysis of how veterans' memoirs depict seven important topics: the demographics of American soldiers, combat, the Vietnamese people, race relations among...

RENT: A Director's Process

RENT: A Director's Process describes the process a director undergoes in the creation of a piece of theater. It uses as its example Temple Theaters' 2010 production of RENT, and it examines how an MFA thesis production encapsulates the material garnered over three years' intensive study in a conservatory setting of the art and craft of directing. It explores the methodologies behind the pre-production process, including concept, approach, design, and casting, and continues into the...

Modulation of the Endogenous Cannabinoid System to Attenuate Inflammation in Central Nervous System Injury

In non-pathological states the central nervous system maintains a degree of immunological privilege. When illness or injury occur, this privilege can be lost and the immune system drives pathology in the brain and spinal cord. More so, resident immune cells, the microglial, act as major effectors of this response. Cerebral ischemia, or stroke, is the fourth leading cause of death in developed nations. After the initial ischemia, the inflammatory response propagates further injury and cell...

LEVERAGING HOTEL PERFORMANCE BY CONSUMER REVIEWS

This study quantifies the business value of consumer reviews and discusses its wider implications to hotel performance, specifically to delineate the unique effects of the User-Generated Content (UGC) components on room sales. In contrast to earlier studies that take consumer reviews as an exogenous factor, this study finds empirical evidence that consumer reviews both influence and are influenced by room sales through a dynamic framework. In consideration of the endogeneity in consumer reviews, this study...

SERUM CYTOKINES INDUCED BY PERFORMANCE OF REPETITIVE TASKS AND THEIR RELATIONSHIP TO SICKNESS RESPONSES

Work-related repetitive strain injury (RSI), one of the work-related musculoskeletal disorders, is the most commonly reported occupational illness, yet the pathophysiological mechanisms are not yet clear. Using our unique RSI animal model, pathophysiological tissue responses can be examined simultaneously with behavioral responses that serve as indicators of sensorimotor function. Studies in humans and with this animal model have shown that prolonged performance of repetitive tasks leads to declines in grip strength and increased of serum...

A fifth research question tested these variables in a model of language learning. The final research question investigated the participants L2-English goal stability over one academic year. The longitudinal study used a mixed-methods, QUAN+qual approach....

HOW TRADITIONAL DEFINITIONS OF AUTONOMY IMPAIR DECISION-MAKING IN SPINAL MUSCULAR ATROPHY AND ALZHEIMER DISEASE

Clinical decision making is influenced by available literature, technology, and guidelines, but also by cultural expectations, physician experience, and personal biases. The treatment of various forms of disability is especially vulnerable to these prejudices. Alzheimer Dementia (AD) and Spinal Muscular Atrophy (SMA) represent forms of cognitive and physical disability, respectively. In severe forms of both diseases, patients are often unable to communicate and do not meet traditional definitions of autonomy. However, physicians and consensus guidelines...

COMBATING HEGEMONIC FORCES, FROM THE CONTINENT TO THE BEAT: CONNECTING AFRICANA PHILOSOPHY TO CRITICAL HIP-HOP PEDAGOGY

One of the most critical issues impeding African American liberation today is the American education system, which overwhelmingly and disproportionately, negatively impacts African American youth. In defiance of the hegemonic system, African American adolescents have created alternative modes of expressing their native African sensibilities, connecting them back to traditional ancestral philosophy; one of the resulting cultural productions is Hip-Hop. The proceeding pages will offer a critical analysis of literature on Philosophy for Children (PFC/PWC), Africana...

SPONTANEOUS HYPOCAPNIA AFTER CARDIAC ARREST IS ASSOCIATED WITH 60-DAY MORTALITY

Background: Hypocapnia exposure after successful resuscitation from cardiac arrest has been previously demonstrated to be associated with poor clinical outcomes. During mechanical ventilation after return of spontaneous circulation (ROSC) it is unclear if spontaneous hyperventilation, as opposed high prescribed minute ventilation, is a common cause of hypocapnia. The objectives of this study were to determine the incidence of hypocapnia induced by spontaneous hyperventilation (spontaneous hypocapnia) among patients successfully resuscitated from cardiac arrest and to test...

EVALUATING PHARMACOKINETIC DRUG-DRUG INTERACTIONS DUE TO TIME DEPENDENT INHIBITION OF CYTOCHROME P450s

Time-dependent inactivation (TDI) of CYPs is a leading cause of clinical drug-drug interactions (DDIs). Current methods tend to over-predict DDIs. In this study, a numerical approach was used to model complex CYP3A TDI in human liver microsomes. Inhibitors evaluated include troleandomycin (TAO), erythromycin (ERY), verapamil (VER), Paroxetine (PAR), itraconazole (ITZ) and diltiazem (DTZ) along with primary metabolites N-demethyl erythromycin (NDE), norverapamil (NV), and N-desmethyl diltiazem (MA). Complexities incorporated in the models included multiple binding kinetics,...

Shape Based Object Detection and Recognition in Silhouettes and Real Images

Shape is very essential for detecting and recognizing objects. It is robust to illumination, color changes. Human can recognize objects just based on shapes, thus shape based object detection and recognition methods have been popular in many years. Due to problem of segmentation, some researchers have worked on silhouettes instead of real images. The main problem in this area is object recognition and the difficulty is to handle shapes articulation and distortion. Previous methods mainly...

Teachers' Work in Trying Times: Policy, Practice, and Professional Identity

This study examined organizational routines and teachers' experiences in two urban public elementary schools. The study advances the scholarship on teachers' work through a nuanced examination of instructional routines in order to illuminate teachers' experiences with accountability based-reforms. Using neoinstitutional theory, this study employed ethnographic methods to examine instructional routines in two schools of varying AYP-status: one high-performing school and one low-performing school. Observations and interviews were conducted with a total of 17 teachers over...

A Search For Belonging: David Foster Wallace's Fictional Communities

As a writer popularly known for his fervent self-interrogations and encyclopedic second novel Infinite Jest, David Foster Wallace’s most apparent significance in US literary history lies in his explicit response to his postmodern predecessors, such as John Barth and Thomas Pynchon. In his now infamous essay “E Unibus Pluram: Television and US Fiction,” Wallace argued that postmodern authors had over-invested in the literary tools of irony and self-reference to such a degree that they became...

Teachers' Perceptions of Factors Used in Placement Decisions

Children with autism spectrum disorders (ASD) are spending greater amounts of time in inclusive classroom settings. The perceptions of teachers regarding the educational placement of children with ASD are a critical topic of study, since teachers are primarily responsible for the implementation of inclusion (Soodak, Podell, & Lehman, 1998). While there is a substantial research base that has examined the attitudes of teachers about inclusion, less research has focused on ASD that compared the attitudes...

Precision Measurement of Longitudinal and Transverse Response Functions of Quasi-Elastic Electron Scattering in the Momentum Transfer Range 0.55 GeV /c ≤ |q| ≤ 1.0 GeV /c

Coulomb Sum Rule states that the integration of the longitudinal response of a nucleus over the range of energy excitation dominated by quasi-elastic proton knock-out process should be equal to the total number of protons in the nucleus. The test of Coulomb Sum Rule will shed light on the question of whether or not the properties of nucleon are modified in the nuclear medium. In order to test the Coulomb Sum Rule in nuclei, a...
