Theses and Dissertations

In this paper I expand on previous research of the determinants of abortion demand to examine the demand for abortion in the specific case of Pennsylvania, where precise statistics are available for each county. The data considered is for the years 2000 and 2010, and allows for cross sectional and panel data analysis, specifically, first-difference permitting to look at the effect of changes over time of specific explanatory variables. Careful attention is placed on variable selection techniques to avoid the use of low significance variables. The analysis allows controlling for price, as it is considered to be constant across the …

The Effect Of Self-Explanation And Strategy Training On L2 Reading Comprehension Using An Intelligent Tutoring System, Hongxia Fu

Theses and Dissertations

While research suggests that secondary language (L2) learners at postsecondary institutions face academic reading challenges, and that reading strategy training can improve primary language (L1) learners' reading comprehension, it remains a challenge to find scalable ways to deliver such training to L2 learners. Intelligent tutoring systems (ITS) have been shown to be nearly as effective as human tutors while reaching potentially unlimited numbers of learners in a variety of subjects, including reading comprehension. However, few studies have explored the effectiveness of such systems for improving L2 learners' reading comprehension. Self-Explanation Reading Training (SERT) is an instructional model that combines self-explanation …

Multiple Baseline Study Of The Effects Of Left Visual Field Stimulation During Emotion Recognition Training Among Four Male Children With Autism Spectrum Disorders, Rachelle Hansen

Theses and Dissertations

Autism Spectrum Disorders (ASD) are characterized by social deficits in emotional comprehension. Research has demonstrated that for the neurotypical population, recognizing, and reacting to facial emotions improve when using the left visual field by employing the right brain hemisphere's configural processes. Behavioral, physiological, and neuroimaging findings suggest an opposite pattern within the autistic population - left hemisphere activation contributing to a right visual field preference for analyzing and assessing facial affect. The present study attempted to activate and strengthen the right hemispheric neural pathway responsible for emotion recognition using modified eyewear to contrive left visual field stimulation during an empirically …

Impact Of Cultural Identity On Mmpi-2 Profiles In Northern Plains American Indians, Colleen Kagan

Theses and Dissertations

American Indian populations experience high rates of psychological distress with 44.5% percent of Northern Plains American Indians reporting experiencing some depressive, anxiety, or substance use disorder over their lifetime. The MMPI-2 is a commonly used psychodiagnostic tool that has become widely used in the mental health treatment of different racial and ethnic groups. Research on the MMPI-2 with minority populations, and American Indian populations in particular, fails to account for the impact of level of acculturation. This study examined the impact of cultural identity on MMPI-2 profiles in Northern Plains American Indians and comparison Caucasian samples. Participants were administered a …

Automated Usability Testing Of Websites Using Link Structure, Christoffer Odegaard Korvald

Theses and Dissertations

Websites keeps getting more important in business and other aspects of society. Making the websites as usable as possible is crucial as difficult to use systems tend to frustrate users, which might lead to users leaving or lost revenue for a business. Usability testing is needed to identify and fix those issues. Manual tests in usability labs can be very time consuming and costly. An automated system could reduce time and cost of testing, but are often too focused on one aspect to give a clear view of what needs to be fixed. A system to improve this is needed. …

Investigation Of The Seasonal Variations Of Aerosol Physicochemical Properties And Their Impact On Cloud Condensation Nuclei Number Concentration, Timothy Logan

Theses and Dissertations

Aerosols are among the most complex yet widely studied components of the atmosphere not only due to the seasonal variability of their physical and chemical properties but also their effects on climate change. The three main aerosol types that are known to affect the physics and chemistry of the atmosphere are: mineral dust, anthropogenic pollution, and biomass burning aerosols. In order to understand how these aerosols affect the atmosphere, this dissertation addresses the following three scientific questions through a combination of surface and satellite observations:

SQ1: What are the seasonal and regional variations of aerosol physico-chemical properties at four selected …

An Investigation On Relationship Between Epistemological Beliefs And Instructional Practice Of Preservice And Inservice Teachers, Jacob Manu

Theses and Dissertations

This quantitative research sought to investigate the relationship between epistemological beliefs and instructional practice of preservice and inservice teachers. Despite the vigorous emphasis and investment on the need for teachers to adopt teaching and learning practices that are more authentic, learner-centered, project-based, meaningful, and context-based, there is a growing trend where inservice teachers are trained in constructivist learning environment but end up adopting traditional learning pedagogies. Thus, teachers are constantly struggling to incorporate the tenets of constructivism into the teaching and learning process. With the use of the discipline-focused epistemological beliefs questionnaire and instructional practice scale, preservice and inservice teachers …

Improving Satellite Quantitative Precipitation Estimates By Incorporating Deep Convective Cloud Optical Depth, Ronald Stenz

Theses and Dissertations

As Deep Convective Systems (DCSs) are responsible for most severe weather events, increased understanding of these systems along with more accurate satellite precipitation estimates will improve NWS (National Weather Service) warnings and monitoring of hazardous weather conditions. A DCS can be classified into convective core (CC) regions (heavy rain), stratiform (SR) regions (moderate-light rain), and anvil (AC) regions (no rain). These regions share similar infrared (IR) brightness temperatures (BT), which can create large errors for many existing rain detection algorithms. This study assesses the performance of the National Mosaic and Multi-sensor Quantitative Precipitation Estimation System (NMQ) Q2, and a simplified …

The Effect Of Non-Weight And Shape-Related Appearance Dissatisfaction On Eating Disordered Behaviors, Terra Towne

Theses and Dissertations

Studies have found that greater dissatisfaction with non-weight-related body parts is associated with drive for thinness and body dissatisfaction, suggesting that eating disorder behaviors may be compensatory mechanisms for less malleable aspects of appearance. The aim of the present study was to explore the relationship between non-weight and shape-related appearance dissatisfaction (NWSAD), perceived malleability, and eating disorder and appearance-related behaviors. Participants were students enrolled in undergraduate psychology courses at a mid-size midwestern university. All participants completed the Eating Disorders Examination Questionnaire, Drive for Muscularity Scale, Body Shape Questionnaire, visual analogue scales assessing NWSAD, appearance-related behaviors checklist, and a measure assessing …

Determining The Origin And Possible Mechanisms Of Qpos In X-Ray Emissions Of Neutron Stars And Black Holes, Brent Thomson

Theses and Dissertations

QPOs (Quasi-Periodic Oscillations) are time oscillations that appear in the light curve of observational data in x-ray bands. They are of mysterious origin although they are believed to be a result of the intense gravity around neutron stars and black holes and emit x-rays from accretion disks. I investigate a derived ratio between two periods has been found in the QPO data. The two periods, which appear as peaks in the power density spectrum have been found to be in a 3:2 ratio and can possibly distinguish theoretical models. In the work presented here, two physical approaches are developed that …
