Recalcitrant Arguments, Kiranjeet Kaur Dhillon

Dissertations and Theses @ UNI

On January 26, 2011, Reuters photojournalist Amr Abdallah Dalsh took an image of a unknown veiled woman gesturing at Dalsh and his camera. Using TinEye, a reverse image search engine, I found that 86 circulations and 22 recirculations of the photo were primarily in the United States. US graphic artist Nick Bygon created one of the recirculations, which primarily appeared on US blogs. The photo achieved this level of circulation in the US because it is consistent with, and therefore legible within the symbolic language, of the liberal democratic order. Similar to “Migrant Mother” and “Tank Man”, the photo is …

Students in the treatment group experienced one semester of blended learning by using online science modules to supplement their in-class learning while the control group continued to have only …

From Sidebets To Sideshow: The Influence Of Gambling On The Development Of Professional Wrestling In America, 1870-1911, Lee Casebolt

Dissertations and Theses @ UNI

While boxing and baseball have been common subjects of historical study, other sports of the nineteenth century have been comparatively neglected by historians. Professional wrestling, in particular, has received very little attention as a sport, as opposed to its twentieth century “sports entertainment” incarnation. What attention it has received has most commonly been through the lens of social history, focusing on wrestling as theater or its psychosexual overtones. Missing from its history is any consideration of the economic factors which influence the evolution of any professional endeavor. This paper explores the relationship between a wrestler’s payment and performance. Specifically, it …

Effects Of Prazosin On Nightmares In Adults With Posttraumatic Stress Disorder, Laurie A. Tefft

Theses and Dissertations

The Diagnostic and Statistical Manual of Mental Disorders (American Psychiatric Association [APA], 2000) estimates that in the United States, Posttraumatic Stress Disorder (PTSD) affects 8% of adults at some point during their life. Nightmares have a severe impact and can cause great distress for individuals with PTSD (Ohayon & Shapiro, 2000). Spoormaker and Montgomery (2008) suggested that sleep problems may be more of a risk factor for PTSD then a symptom of the disorder. Either way, it is evident that sleep needs to be addressed in those with this diagnosis. Posttraumatic nightmares are seldom the topic of PTSD studies utilizing …

Predicting Commitment For Those In Military Relationships, Darrina Sofia Bledsoe

Dissertations and Theses @ UNI

Little research has been conducted concerning how deployments affect spouses' and service members' commitment to their relationships (Merolla, 2010). The current study investigated relationship commitment of military spouses and service members in long-distance relationships (LDR) and geographically close relationships (GCR). The investment model (IM; Rusbult, Martz, & Agnew, 1998) predicts that relational commitment is influenced by three factors: satisfaction, alternatives, and investment. Additionally, the perceived stress scale (PSS; Cohen, Kamarack, & Mermelstein, 1983), which focuses on levels of stress influenced by daily hassles, major events, and changes in coping resources, was utilized as a means to predict commitment in conjunction …

Theses and Dissertations

Clinical laboratory test results are integral to patient management. Important aspects of laboratory tests’ contributions are the use of the test information and the role they have in facilitating efficient and effective use of healthcare resources. Methods of measuring those contributions were examined using quantitative HCV RNA test results (HCV VL) in therapeutic management decisions as a model. Test precision is important in those decisions; therefore, the clinical use was evaluated by studying the impact that knowledge of inherent assay imprecision had on clinicians’ decisions. A survey describing a simulated patient at a decision point for HCV triple-combination therapy management …

Development And Validation Of A Predictive Model Of Return-To-Work Outcomes Of Injured Employees In Minnesota, A. Bentley Hankins

Theses and Dissertations

In Minnesota’s workers’ compensation system, injured employees at risk for sustaining permanent disability may be eligible for receipt of vocational rehabilitation (VR) services if they are determined to be capable of benefitting from such services. VR services can be a valuable resource to injured employees who need assistance minimizing their work disability and maximizing their residual wage-earning capacity. However, for VR services to be effective at a system level, it is necessary to precisely and accurately identify an injured employee’s rehabilitation potential. Failure to do so is likely to result in the misallocation of a scarce and costly resource. Given …

Correcting Heat Flow Data In The United States To Account For Climate Change, Godswill Njoku

Theses and Dissertations

Heat flow measurements may require correction for both recent warming and post-glacial warming signals. Warming during the last century can be detected in borehole temperature profiles. Both climate warming signals during the past century and post-glacial warming signals during the past 10 millennia are greatest near the surface and diminish with depth.

Both atmospheric data and borehole temperature data show that recent warming varies systematically with latitude along a north-south transect in the United States. The systematic increase with latitude from +0.7 oC at 41.6oN to +2.3 oC at 49oN during the last century is consistent with the prediction that …

Geomechanics And Elastic Anisotropy Of The Bakken Formation, Williston Basin, Mehdi Ostadhassan

Theses and Dissertations

Many of the earth’s rocks exhibit anisotropic characteristics. Anisotropy is particularly common in many sedimentary rocks, such as shales. Anisotropy is defined as the spatial alignment of mineral grains, layers, fractures and stresses which causes elastic wave velocity and other elastic properties to vary with direction. There are two types of anisotropy: intrinsic and stress-induced. Intrinsic anisotropy is caused by beddings, microstructures or aligned fractures formed during deposition. Stress-induced anisotropy is caused by strain associated with external stresses. Intrinsic anisotropy originates in the absence of external stresses, while stress-induced anisotropy results from tectonic and overburden stresses. The style of earth …

Research About Low Permeability Measurement, Jun He

Theses and Dissertations

Petroleum exploration and production from shale formations have gained great attention throughout the world in the last decade. Producing the hydrocarbons from shale is challenging because of the low porosity and permeability. It is imperative to investigate permeability of the shale formations in order to better understand the performance of wells that are producing hydrocarbons from shale. Permeability is also one of key parameters in modeling fluids flow in matrix in reservoir simulation. Due to the low or very low permeability, the measurement of permeability is time consuming and expensive. These factors often limited the ability to perform permeability measurement …

Hydraulic Fracturing Design For Horizontal Wells In The Bakken Formation, Williston Basin, Hadi Jabbari

Theses and Dissertations

Unconventional hydrocarbon reservoirs have proved to be challenging in terms of reservoir characterization, predicting production potential, estimating ultimate recovery, and optimizing hydraulic fracture stimulations. The methods by which these resources are extracted use progressive, or unconventional, technologies. Today, through the use of hydraulic fracturing and horizontal drilling, extraordinary amounts of oil and natural gas from deep shale formations across the United States and around the world are being safely produced.

Performing a hydraulic fracture design requires modeling of fracture propagation and tracking the fluid front in the created fracture. In this dissertation, the roles of all effective parameters and properties …

Olfactory Preference For Ethanol Following Social Interaction With An Intoxicated Peer In Adolescent Rats Exposed To Ethanol In-Utero, Samanta M. March, Ricardo M. Pautassi, Michael Nizhnikov, Juan Fernandez-Vidal, Norman E. Spear, Juan C. Molina

Psychology Faculty Scholarship

Background: Prenatal exposure to ethanol and later socially mediated exposure predicts ethanol intake in human adolescents. Animal rat models indicate that brief interactions with an ethanol-intoxicated peer result in heightened preference for ethanol odor and ethanol intake. Methods: This study assessed preference for ethanol odor in adolescent male rats (observers) following social interaction with an ethanol intoxicated peer (demonstrators) as a function of prenatal ethanol exposure (gestational days 17-20, 1.0 g/kg, intragastric). Social behavior and locomotion during social interaction was also measured. Results: Social investigation was greater in observers that interacted with an intoxicated demonstrator in comparison to those that …

Negotiation Stands Alone, Alexandra Crampton, Michael Tsur

Social and Cultural Sciences Faculty Research and Publications

Yes, the authors concede, “everybody” negotiates: but that’s like saying “everybody drives,” and then watching aghast when “everybody” climbs into a racing car, or an eighteen-wheeled tractor trailer. The authors draw from Tsur’s experience teaching Israeli hostage negotiators and in other high-pressure environments to argue for an entirely distinct concept of a professional negotiator, one that starts with a rather experienced “student” and builds a sharply different training regimen from there.

Code Clone Discovery Based On Concolic Analysis, Daniel Edward Krutz

CCAC Theses and Dissertations

Software is often large, complicated and expensive to build and maintain. Redundant

code can make these applications even more costly and difficult to maintain. Duplicated

code is often introduced into these systems for a variety of reasons. Some of which

include developer churn, deficient developer application comprehension and lack of

adherence to proper development practices.

Code redundancy has several adverse effects on a software application including an

increased size of the codebase and inconsistent developer changes due to elevated

program comprehension needs. A code clone is defined as multiple code fragments that

produce similar results when given the same input. …
