Trauma Experiences And Symptoms Reported By American Indian And Caucasian Sex Offenders, Regina Sioux Ertz

Theses and Dissertations

American Indian/Alaskan Native (AI/AN) people are known to have a history of man-made trauma that corresponds to the colonization of the Americans. Trauma experienced by AI/AN sex offenders has not been evaluated in the research as it relates to their treatment planning. The lack of data reflecting intervention needs for AI/AN sex offenders is problematic. The current study hypothesized that American Indian sex offenders would report a greater number of trauma experiences, endorse increased symptoms of Posttraumatic Stress Disorder (PTSD), display more traumatic cognitions, and endorse higher dissociative experiences than Caucasian sex offenders. Statistical results yielded did not support the …

Grade Level Retention: A Comparative Study Of Beliefs And Practices In North Dakota And Surrey, Kim Englund

Understanding Somali Women Refugee Students' Lives And Program Decisions At Two-Year Colleges: A Narrative Approach, Mary Fontes

Theses and Dissertations

The purpose of this research was to explore Somali women refugee students' lives and to identify what factors influenced their program decisions at two-year colleges in the Midwest. Refugees have been admitted to the United States (U. S.) as early as 1948 under the Displaced Persons Act. Some states have experienced a greater influx of refugees than others. Employment and economic self-sufficiency are emphasized as quickly as possible after arrival in the United States. Some foreign-born individuals, who aren't prepared for employment, pursue education. Somali women refugees who pursue education may be doing so unprepared or counter to cultural norms …

Early Intensive Behavioral Intervention For Autism: Is It Actually More "Intensive" Than A Typical Child's Day?, Caitlyn B. Sorensen

Master's Theses and Doctoral Dissertations

Autism Spectrum Disorder (ASD) is a pervasive developmental disorder characterized by deficits in social interaction, communication, and excessive ritualistic and repetitive behavior. Numerous treatments for autism devised over the last half-century have proven ineffective, or have never been scientifically evaluated. Despite the state of the research, the most demonstrably effective treatment, Early Intensive Behavioral Intervention (EIBI), has been a target of much criticism, including accusations of being too intense. A large number of learning trials in relatively short periods of time supposedly induce children to have disordered stress responses. To explore the intensity of EIBI, behavior samples from children engaging …

A Study Of Teacher Perceptions Of The Use Of Student Growth Measures In Teacher Evaluation And Its Effect On School Culture, Jennifer L. Slanger

Master's Theses and Doctoral Dissertations

This study explored teacher perceptions of the inclusion of student growth data into the teacher evaluation process and the relationship(s) these perceptions might have on school culture. A positive correlation (p <.001) was found between the inclusion of VAM into the teacher evaluation process and motivation to collaborate. Key findings include participants working in priority designated schools were less likely to collaborate; participants with more knowledge about VAM had more positive perceptions; and participants in nonurban schools or smaller schools had more positive perceptions of VAM. Significant main effects for urban location (p = .001), number of teachers (p = .005), and level of knowledge (p = .05) were found. Participants in priority or urban schools indicated they don’t want to collaborate at a higher level than their counterparts in non-priority or nonurban schools. The inclusion of VAM appears to lead participants into isolation, not necessarily competitive relationships.

There are two forms of IgY expressed in anseriformes birds, a full length IgY that is functionally similar to mammalian IgG, and an alternatively spliced IgY, IgY(ÄFc), that is comparable to the mammalian F(ab')2 fragment. The difference in …

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 Reverse Ethnocentrism On Competence Regarding Food Related Behaviors As A Function Of Attachment Style, Ethnic Identity, And Locus Of Control, Sheryl Holter Vogel

Theses and Dissertations

The present study investigated associations between attachment styles, locus of control (LOC), ethnic identity, and competence regarding food-related behavior (competence) among 168 White and 61 American Indian participants. An experimental manipulation was also conducted in which the concept of reverse ethnocentrism was tested. Attachment style accounted for the most significant variance of competence at 9% followed by ethnicity at 2%. Ethnic identity and LOC accounted for nonsignificant variance at 4% and less than 1% respectively. Prior to the experimental manipulation, results found competence was significantly negatively associated with low anxiety and high avoidance (dismissing attachment style), and American Indian participants …

Pleas For Partition In Train To Pakistan, Md. Abu Jafor

Theses and Dissertations

Pleas for Partition in Train to Pakistan

Most readers and critics of fictional works about the Partition of British India (that is the division of British India into India and Pakistan upon independence from the British in 1947) agree that writers tend to paint religious differences as the root cause of the communal conflict that eventually led to Partition. This tendency to blame Partition on religion is also found in critics who study Khushwant Singh's novel Train to Pakistan. In contrast, this thesis will demonstrate that instead of blaming communal diversity (in other words "difference of religion") as the root …

Autonomous Spacecraft Control During Close-Proximity Near-Earth Object Operations, Joshua Thomas Johnson

Theses and Dissertations

A control scheme is proposed for a satellite orbit controller around a small, irregularly shaped near-Earth object (NEO) combining classical control theory and orbital mechanics into a continuous hybrid control system that achieves and maintains a circular orbit in a perturbed environment. NEOs are asteroids and comets that approach Earth's orbit around the Sun. They are currently being studied for resource allocation and threat mitigation, while providing unique opportunities for control systems. The NEO environment consists of a weak and complex gravity field, as well as other perturbations such as solar radiation pressure (SRP) and third-body gravitational disturbances. This project …

Homicides And The American Dream: An Empirical Application Of Institutional Anomie Theory At The Census Tract Level, Stacie Jergenson

Theses and Dissertations

Guided by the Institutional Anomie Theory (IAT) of Steven F. Messner and Richard Rosenfeld (2007), this study examines the strength and interaction of social institutions (economy, education, family and polity) in relationship to homicides occurring in Minneapolis, Minnesota between 2007 and 2011. It utilizes census tracts as the units of analysis, an attempt to extend IAT from the cross-national to the local level. Rather than focusing on specific offenders, it explores broader cultural and structural characteristics employing exploratory, ordinary least squares (OLS), and geographically weighted regressions (GWR). Although interactions did not reach statistical significance, relationships were found between homicides rates …

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. …

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