Exploring Additional Factors Of Presence, Dustin Chertoff

Electronic Theses and Dissertations

One of the oft cited reasons for virtual environments is that they provide experiences with places one would never be able to visit and to perform tasks that would otherwise be dangerous, or inaccessible. The ability to become transported to another environment, such that you think you are "there," is known as presence. Existing presence literature focuses largely on the sensory aspects of virtual environment experiences. However, there is more to experience than what is sensed. This dissertation investigates the theoretical components of holistic experiences in virtual environments. In order to explore the relationship between experiential design and presence, a …

Using Student Mood And Task Performance To Train Classifier Algorithms To Select Effective Coaching Strategies Within Intelligent Tutoring Systems (Its), Robert Sottilare

Electronic Theses and Dissertations

The ultimate goal of this research was to improve student performance by adjusting an Intelligent Tutoring System's (ITS) coaching strategy based on the student's mood. As a step toward this goal, this study evaluated the relationships between each student's mood variables (pleasure, arousal, dominance and mood intensity), the coaching strategy selected by the ITS and the student's performance. Outcomes included methods to increase the perception of the intelligent tutor to allow it to adapt coaching strategies (methods of instruction) to the student's affective needs to mitigate barriers to performance (e.g. negative affect) during the one-to-one tutoring process. The study evaluated …

Concept Learning By Example Decomposition, Sameer Joshi

Electronic Theses and Dissertations

For efficient understanding and prediction in natural systems, even in artificially closed ones, we usually need to consider a number of factors that may combine in simple or complex ways. Additionally, many modern scientific disciplines face increasingly large datasets from which to extract knowledge (for example, genomics). Thus to learn all but the most trivial regularities in the natural world, we rely on different ways of simplifying the learning problem. One simplifying technique that is highly pervasive in nature is to break down a large learning problem into smaller ones; to learn the smaller, more manageable problems; and then to …

Geometric Invariance In The Analysis Of Human Motion In Video Data, Yuping Shen

Electronic Theses and Dissertations

Human motion analysis is one of the major problems in computer vision research. It deals with the study of the motion of human body in video data from different aspects, ranging from the tracking of body parts and reconstruction of 3D human body configuration, to higher level of interpretation of human action and activities in image sequences. When human motion is observed through video camera, it is perspectively distorted and may appear totally different from different viewpoints. Therefore it is highly challenging to establish correct relationships between human motions across video sequences with different camera settings. In this work, we …

Sister Katie: The Memory And Making Of A 1.5 Generation Working Class Transnational, Caroline Waldron Merithew

History Faculty Publications

Identifying the theoretical and chronological fault lines that divide immigration and women’s history, I use memory and biography to argue that assimilation and transnationalism in the 1.5 and second generations were not oppositional. In this article, I tell the story of an Italian immigrant who moved to the United States as a young child and who became a self-proclaimed “left winger.” I cast Katie’s story less from her own words as from the recollections of others who remade and remembered her from the 1930s until 1960. I argue that a working-class transnational’s identity was one that could move through large …

Running The Ancient Ark By Steam: Catholic Publishing, 1880-1950, Una M. Cadegan

History Faculty Publications

This essay highlights two aspects of Catholic culture related to books and reading between 1880 and 1940: the connection between.material objects and the printed word, and the role of authority in shaping both the institutional aspects and the content of Catholic publishing. It also emphasizes how, in their tumultuous but thriving print culture, U.S. Catholics adopted technically and organizationally advanced processes in the pursuit of religious and cultural goals that were, in the eyes of their contemporaries, perceived as largely modern.

Revisiting The Un Protocol On Human Trafficking: Striking Balances For More Effective Legislation, Kalen Fredette

Cardozo Journal of International and Comparative Law

Human trafficking is a growing global criminal concern. This paper assesses several national and multi-national efforts to combat human trafficking, focusing particularly on the UN Protocol to Prevent, Suppress and Punish Trafficking in Persons, Especially Women and Children (Protocol). Ultimately, the rise in trafficking offenses compared to the sparse number of convictions strongly suggests the inadequacy of the national and multinational efforts currently in play. This paper will take a fresh look at key provisions of the recent Protocol in light of newly published data on trafficking, and will explore possible modifications to the instrument which may increase its effectiveness. …

The Rocky Path From Section 601 Of The Iirira To Issue- Specific Asylum Legislation Protecting The Parents Of Fgm-Vulnerable Children, Andy Rottman

University of Colorado Law Review

Political asylum in the United States is intended to protect those who fear persecution if they are returned to their country of origin. Arguably, the United States asylum system works reasonably well when the asylum seeker fits neatly within the statutory asylum scheme. If, however, asylum seekers' claims fall outside the statute, the asylum system can work inhumane results. In these situations, Congress can use issue-specific legislation to protect a group facing a discrete humanitarian crisis. This was done in section 601 of the Illegal Immigration Reform and Immigrant Responsibility Act of 1996 ("IIRIRA"), which explicitly provided asylum protection to …

Ask For It: The Impact Of Self-Esteem, Situational Characterization, And Gender On The Propensity To Initiate Negotiation, Anna Beninger

CMC Senior Theses

This study analyzes the impact of self-esteem (high vs. low), situational characterization ("negotiate" vs. "ask"), and gender (men vs. women) on the likelihood an individual initiates negotiation (n = 140). Self-esteem was primed with a prompt and the participants were told they could either "negotiate" or "ask" for more money after completing two tasks. A main effect of situational characterization was found such that negotiation was more likely in the "negotiate" condition than in the "ask" condition. Neither self-esteem nor gender produced significant results. A significant interaction showed that men were more likely to negotiate in the "ask" condition, but …

Algoritmo De Tratamiento Multimodal Para Preescolares Latinoamericanos Con Trastorno Por Déficit De Atención Con Hiperactividad (Tdah), Juan David Palacio, Matilde Ruiz-García, José J. Bauermeister, Cecilia Montiel-Nava, Gloria C. Henao, Guillermo Agosta

Psychological Science Faculty Publications

Introduction During the first Latin American ADHD consensus held in Mexico in 2007 a treatment algorithm for attention-deficit/hyperactivity disorder (ADHD) in preschoolers was proposed. Since then, some studies have emerged regarding not only pharmacological treatment but also psychosocial managing strategies for this population that require a review. The main objective was to review the recent literature on preschool ADHD clinical management in order to update the treatment algorithm and to include together both psychopharmacological treatment and psychosocial management strategies into the decision tree.

Method A task force with six experts from five Latinamerican countries was constituted. The task force included …

An Analysis Of The Effectiveness Of Functional Behavioral Assessment For Students With Emotional Behavioral Disabilities, Megan Kale Brose

Dissertations and Theses @ UNI

Functional behavioral assessment (FBA) is defined as "a set of assessment procedures used to identify variables that promote and maintain challenging behavior and based upon this assessment, interventions are selected that alter one or more of these variables" (Stichter & Conroy, 2005, pp. 19-20). FBA has received a great deal of attention since the passage of the Individuals with Disabilities Education Act (IDEA)l997 amendments, which require the use of FBA for all special education students upon referral of alternative educational placements due to behavior resulting in disciplinary action. There has also been considerable questioning of and need for research in …

An Exploration Of The Relationship Between Student Experiences In The School Environment And School Belonging, Erin E. Welsh

Dissertations and Theses @ UNI

Researchers have worked for years to decrease rates of student dropout by identifying associated factors, and developing strategies to increase school success. Despite these efforts, dropout is a complicated phenomenon, making it difficult to effectively support students. There is a body of literature concerning the connection between students' sense of belonging and its relationship to dropout. This literature is reviewed in light of the effect teachers, parents, peers, and personal characteristics have on belonging and dropout. A second body of research concerning how the physical environment of schools as behavior settings affects student outcomes is also discussed. A survey was …

Rape Myth Acceptance In A Dynamic Environment: Application Of Social Impact Theory To Rma, Zebbedia G. Gibb

Dissertations and Theses @ UNI

This study examines conditions under which attitudes related to sexual assault, commonly known as rape myths, may be transmitted through culture by applying the tenets of Social Impact Theory (Latane, 1981). Social impact theory suggests that three forces influence attitude change, namely the immediacy of the source to the target, the strength of the source, and the number of sources of a message. It was hypothesized that participants who chatted with a confederate who was similar to them and endorsed rape myths would report accepting those beliefs at a higher rate than participants who chatted with a confederate who was …

Arabs And Muslims In Orientalist Hollywood: Trends In Perception Before And After 9/11, Marwa Hassan Genena

Dissertations and Theses @ UNI

Before 9/11, almost all Hollywood Orientalist films fit the tenets of Orientalist discourse, which Edward Said describes in Orientalism. Brushed with a series of negative qualities, the Oriental character is usually represented as an absolute opposite to the Western character, whose perfection is highlighted by the former's numerous flaws. Not only is the Arab or Muslim character in pre-9/11 Hollywood dumb and inept, but evil and dangerous as well. Additionally, Orientalist filmmakers avoid a solid, deep construction of their Arab or Muslim characters in such a way that the personal or humane side of these characters is completely ignored. In …

A Test Of Ajzen’S Theory Of Planned Behavior: Predicting Students’ Intentions Toward Joining An Army Rotc Program, Jason Hornberg

Dissertations and Theses @ UNI

Young adults' expressed interest toward joining The Unites States Armed Forces has been decreasing since the 1990's. This downward trend has negatively influenced the recruitment of enlisted soldiers into the military as well as the enrollment of young adults into officer production programs like the Reserve Officer Training Course (ROTC). In an attempt to understand and overcome the effects of this trend, behavioral scientists have begun using behavioral theories to predict young adults' intention toward joining the military. One theory that has been frequently used to predict intention and behavior is Ajzen's theory of planned behavior. Ajzen' s theory of …

Further Delineation Of The Role Of The Amygdala In Face Processing And Racial Categorization, Osman Afzal Chowdhry

Dissertations and Theses @ UNI

DNA exonerations in the legal system have increased steadily since 1989 from one or two per year to an average of 21 per year since 2001. A disquieting number of these exonerations originated from wrongful convictions following cross-racial identifications. Explaining the prevalence of erroneous cross-racial identifications centers on the Cross Race Effect (CRE), a phenomena whereby recognition for one's own race greatly outweighs recognition ability for other-race faces. Forty years of research in this area has produced a number of competing explanations. Recent neurological evidence has demonstrated separate neural regions for the processing of same-race and other-race faces as well …

The Aims Of Public Scholarship In Media Law And Ethics, Erik Ugland

College of Communication Faculty Research and Publications

This essay urges scholars in media law and ethics to reevaluate the extent and utility of their public-scholar efforts and to consider ways that they can transfer research-based knowledge to public audiences while also playing a more deliberate role in holding media and government institutions accountable. It suggests that the devolution of standards in mass communication, the increasing encroachments on media autonomy, and the broader collapse of power into fewer hands make this a particularly urgent moment for scholars to reengage the public and to abandon their feckless neutrality on public issues. The overarching aim of public scholars ought to …
