Automotive Service Technology Intersectional Skills Proficiency Assessment, David L. Macquarrie

Dissertations

This dissertation focused on the creation and validation of a criterion referenced credentialing assessment of automotive service technicians' intersectional skills (ASTIS) proficiency. These intersectional skills are prerequisite and common to multiple job level tasks that an automotive service technician (AST) performs on the job. An assessment of the ASTIS was created to aid automotive technician employers in the evaluation of hiring prospective technician employees and is not duplicated by current certifications (e.g. ASE) as they do not uniquely assess these skills.

This dissertation focused on the ASTIS skills and the information an employer can obtain pertaining to a prospective employee's …

Hacks, Cracks, And Crime: An Examination Of The Subculture And Social Organization Of Computer Hackers, Thomas Jeffrey Holt

Dissertations

This dissertation examines both the subculture and social organization practices of computer hackers. The concept of normative orders (Herbert, 1998: 347) is used to explore hacker subculture in different contexts. To assess hacker social organization, I use Best and Luckenbill¿s (1994) framework of organizational sophistication as well as measures from Decker et al. (1998). The relationships between subculture, social organization, and behavior are explored as well. I collected three qualitative data sets to explore these issues, including posts from six on-line hacker discussion forums, in-depth interviews with active hackers, and field observations at the Defcon 12 hacker convention. These data …

Psychosocial Responses By Adolescent Male Victims To Peer Bullying, Karin Eve Reuter-Rice Phd

Dissertations

Bullying remains a pervasive problem in most schools throughout the nation. Peer-bullied victims report higher levels of depression, suicidal ideation, anxiety, and concerns regarding their safety in school. Reactions of victims to peer bullying have been extreme, as in the cases of the rampage school shooters. Primarily, current research has not focused on the high school adolescent, although most school shooters arise from that age group. The overall purpose of this study was to examine the psychosocial responses by adolescent male victims to peer bullying. Research questions addressed the frequency and severity of peer-victimization, distress, anxiety, and their perception of …

Nursing Students' Knowledge And Attitudes Regarding Pain And Pain Management, Ruth L. Schaffler Phd

Dissertations

Pain is a universal human experience and is a primary reason people seek health care; however, undertreatment of pain has been reported in the literature as a significant clinical problem for more than three decades. Researchers have concluded that nurses have inadequate knowledge of pain assessment, are misinformed about opioids, and have inappropriate attitudes about pain and pain management that lead to the undertreatment of pain. One question is whether those misconceptions are acquired in nursing school or whether they are present when students enroll in nursing programs. The purpose of this quasi-experimental study was to examine the attitudes regarding …

Variable Permittivity Dielectric Material Loaded Stepped-Horn Antenna, Ozgur Ozdemir

Dissertations

Stepped-horn antenna loaded with dielectric material of variable permittivity is proposed to improve radiation characteristics and/or to increase the electrical dimensions of the radiating structure compared to unloaded empty one. A hybrid numerical technique is used to analyze such an antenna. The tapered section of the horn antenna is modeled by multi-stepped waveguide structures filled with variable dielectric constant material. Generalized scattering matrix representation of the tapered section of the horn antenna is obtained using mode matching technique. The radiating aperture problem is solved by the method of moments, under the assumption that the horn is terminated by an infinite …

Exploration Of Ideal Body Image Among African-American Women, Shannon Denise Nickens

Dissertations

Body image dissatisfaction is a pervasive problem, most notably among women, that is neither well understood nor well defined. Inconsistent and overly narrow definitions of body image make it difficult to draw conclusions regarding the degree and type of dissatisfaction across cultural and/or various ethnic groups. Thus far, research has largely focused on size, shape, and weight concerns, ignoring physical features that may be salient to women belonging to non-Caucasian ethnic groups. This study explored African-American (AA) preferences for weight, waist-to-hip ratio (WHR), and salient physical appearance attributes, as well as their identification with the ¿thin¿ ideal, racial identity salience, …

The Lost Journals Of Sylvia Plath, Kimberly Dawn Knutsen

Dissertations

Sylvia Plath is one of the few authors who has been posthumously awarded the Pulitzer Prize. Plath's exceptional literary career is not limited with that. When twentieth-century literary history is examined, it becomes patent that no writer has created such an enormous impact as Sylvia Plath. Furthermore, no writer or poet has been as misunderstood as in the case of Plath. In addition, no writer or poet has been labeled often as "schizophrenic" or "mad" by scholars or researchers who do not have the slightest education in psychology or psychopathology. Therefore, the works written on Plath, or the studies that …

Connecting The Dots: A Study Of An Innovative Principal Preparation Program's Impact On The Mental Models And On-The-Job Behaviors Of Aspiring School Leaders, Rich Newman Edd

Dissertations

Despite years of criticism aimed at university-based principal preparation programs, most of these programs continue to be judged less than successful in producing effective school leaders. Furthermore, there is also little rigorous and systemic research about principal preparation in general; there is even less work focused on understanding how preparation programs might assist emerging school leaders in developing the sorts of intellectual capacities needed to be successful in an era when principals are expected to be instructional leaders and work with teachers to improve student achievement. Consequently, little is known about how principal preparation programs can help individuals (a) incorporate …

Incidence And Clinical Predictors Of Risk Factors For Inappropriate Shock In Patients With Implantable Cardioverter-Defibrillators, Shu-Ling Lo Phd

Dissertations

Sudden cardiac death (SCD) is a major unresolved medical problem worldwide. Although Implantable Cardioverter-Defibrillators (ICD) are highly effective in diagnosing and treating life threatening arrhythmias, inappropriate shock therapy (IST) occurs in approximately 5-20% of ICD recipients. IST results in pain, anxiety, induction of ventricular arrhythmias, decreased battery longevity, and even death. Researchers studying clinical predictors of IST have drawn findings based on single case studies with small samples or with outdated data. This study filled this gap by describing the incidence and co-existing clinical predictors of IST. Methodology This descriptive, retrospective study analyzed the incidence and clinical predictors of IST …

An Exploratory Study Of Functional Status In Post Cardiac Arrest Survivors Discharged To Home, John J. Whitcomb Phd

Dissertations

Cardiopulmonary arrest is a major health problem, claiming 350,000 to 450,000 lives per year in the United States, but survival has increased to 49% from the use of Automated External Defibrillators (AED) by lay personnel. Leidy's work on functional status is a comprehensive framework to describe functional status and has not been used in this population. The specific aims of the project were to describe perceived functional capacity, physical functional performance, mental health, symptom distress, and demographic factors in survivors of cardiopulmonary arrest after discharge to home and to examine the relationship among perceived functional capacity, mental health and physical …

Intergenerational Power Exchange Model: Meta-Analysis Of Male Batterers’ Intervention Programs, Suzanne Van Weelde

Dissertations

Domestic violence is an ongoing social problem. Many women have suffered from the abuse of spouses and boyfriends. A number of children have been victims, or witnesses of, this particular form of violence. The consequences of abuse are: preventable crimes, victims and witnesses becoming abusers themselves, escalating health and mental costs. Domestic violence has touched every community within the United States. It is not a social problem that sociological researchers can afford to minimize.

Sociological literature has documented the growth of the social problem of domestic violence. As a result of the awareness of domestic violence as a serious social …

The Relationship Between Counselor-In-Training Personality Traits, Family-Of-Origin Characteristics And Working Alliance, Anthony W. Tatman

Dissertations

Research has revealed that the working alliance between counselors-in-training (CITs) and their clients predict therapeutic outcome (Horvath & Symonds, 1991; Parish & Eagle, 2003). The amount of research is limited, however, concerning CIT traits that facilitate the development of the working alliance (Ackerman & Hilsenroth, 2001; Ligiero & Gelso, 2002; Wampold, 2001). The purpose of the present study was to identify the degree to which CIT personality traits and family-of-origin (FOO) characteristics are associated with working alliance evaluations. This study utilized the 5 domains of personality, measured by the NEO-FFI (Costa & McCrae, 1992), and alexithymia, measured by the TAS-20 …

The Role Of Embeddedness Factors In Predicting The Paths Of The Unfolding Model Of Voluntary Turnover, Lynn R. Kalnbach

Dissertations

A great deal of research has been conducted to determine the relationship between the job satisfaction of employees and the likelihood of their leaving or intending to leave an organization. However, research addressing other reasons why employees may leave their organizations has been lacking. Lee and Mitchell (1994) created the unfolding model of turnover to better define and classify the process employees go through in making decisions to leave their organizations. This model suggests that many people decide to leave their jobs/organizations for reasons other than job dissatisfaction.

In a separate stream of research, Lee and Mitchell and their colleagues …
