Psychometric Properties Of Diagnostic Assessment Instrumentsfor Autism Spectrum Disorders In A Community Sample Aged 2 Through 17 Years, Sheryl Lozowski-Sullivan

Dissertations

Recent estimates of the incidence and prevalence of autism spectrum disorders (ASDs) indicate substantial increases over the past 20 years (Centers for Disease Control and Prevention, 2009; Fombonne, 2009; Matson & Kozlowski, 2011; Schreibman & Koegel, 2005; Wing & Porter, 2002), in part because of the availability of significantly improved diagnostic assessment instruments (Lord & Corsello, 2005; Schreibman, 2005). In highly structured research settings, some of these diagnostic instruments correlate well with each other; however, few studies have examined the relation between these diagnostic tools in traditional clinical practice (Mazefsky & Oswald, 2006; South et al, 2002). This study examined …

Alvar Nuñez Cabeza De Vaca Y Sus Narrativas Sobre La Exploracion Del Rio De La Plata (1540-1545), Maria Del Pilar Lopez-Castilla

Dissertations

Alvar Nunez Cabeza de Vaca remains one of the most enigmatic and audiences on both sides of the Atlantic, from the ruling elite to the wider public, are given the tools to understand and shape the new spheres of public life. Writing becomes a powerful tool in the shaping of a new reality, and as such, it must be studied with extreme care, so that a modern reader is able to discern where history ends and fiction or manipulation of history begin. The contact and constant negotiations for power between the two worlds cause a restructuring of the old discursive …

Recruitment To Leadership Positions In The German Bundestag, 1994-2006, Melanie Kintz

Dissertations

This dissertation looks at the recruitment patterns to leadership positions in the German Bundestag from 1994 to 2006 with the objective of enhancing understanding of legislative careers and representation theory. Most research on political careers thus far has focused on who is elected to parliament, rather than on which legislators attain leadership positions. However, leadership positions within the parliament often come with special privileges and can serve as stepping stones to higher positions on the executive level. Based on a data set I compiled of all members who served in the Bundestag from 1994 to 2006, this dissertation looks at …

Understanding The Dimensions Of Spirituality In Caucasian Lesbian, Gay, And Bisexual College Students, Michele L. Mcgrady

Dissertations

Spiritual development is a critical task for college students, but there is a paucity of information about how college students understand the construct of spirituality. Historically, organized religion has been oppressive to the lesbian, gay, and bisexual (LGB) community. Furthermore, little is known about the spiritual understandings and spiritual experiences of lesbian, gay, and bisexual college students. This quantitative investigation sought to understand the underlying dimensions of spirituality for Caucasian LGB college students through the use of multidimensional scaling. Sixty Caucasian LGB college students were recruited through purposeful and snowball sampling. Findings indicate three dimensions of spirituality for this sample: …

The Effects Of Yellow Rectangular Rapid-Flashing Beacons (Rrfbs) Onmotorists' Yielding, Exit Lane Encroachment And Conflicts At Fire Station Exits, Erick K. Marmolejo

Dissertations

The purpose of the current study was to explore the extent to which yellow rectangular rapid-flashing beacons (RRFBs) affected motorists' yielding, exit-lane encroachment and conflicts at fire station exits. This study explored the use of RRFBs attached to sign prompts that alerted motorists to the presence of exiting emergency vehicles. These signs were activated only during an exit event. It was hypothesized that motorists would increase their frequency of safe and legal yielding in the presence of the RRFB intervention when compared to the absence of contextually activated RRFB units. This study was conducted in a midwestern town in front …

Dissertations

This project bridges the academic fields of comparative religion and children's literature by examining depictions of religious experience in children's literature. I specifically discuss how female religious experience and morality are depicted in three single-author series for girls set between 1850 and 1900—the Elsie Dinsmore series by Martha Finley, the Little Women series by Louisa May Alcott and the Little House series by Laura Ingalls Wilder.

I examine the moral principles of honesty and obedience, longsuffering contentment and industriousness and how they can come together to contribute to the development of a sensitive conscience which can encourage a sense of …

Virtual Design Verification And Process Improvement Of Composite Sheet Material Products Using Intelligent Finite Element Analysis (Ifea), Sathyanarayanan Narasimhan

Dissertations

Engineering design decisions influence more than 70% of product costs. Various computational analysis tools such as Finite Element Analysis (FEA) are typically utilized, to achieve an effective design cycle. Literature review in design process indicates a striking reality that about 75% of design errors can be eliminated through analysis and about 20% of analyses are misrepresented, leading to inadequate or faulty design. Also, analyses in general, generate more information about the problem than is often looked into, leading to a vast potential to study the knowledge creation.

This research bridges these gaps in design process through efficient use of computer-based …

White Male College Students: An Examination Of Identity Development, Masculinity, And Institutional Connections, Randy Ott

Dissertations

White, male college (WCM) students have been a central focus of researchers in higher education throughout its existence, but have not been studied as a group whose identity development is a key issue. This study looked at WCM, their masculinity levels, and how their past connections with peers, instructors, or staff influenced their White identity development. In this study I utilized a phenomenological research approach to learn about the lived experiences of eight WCM. The eight WCM were at least junior status at a medium size, Midwestern, public university.

The results point to multiple conclusions and themes. This study supported …

The study sought to determine: (1) the perception of A/A teachers concerning their K-12 teaching experiences when disaggregated by the number of years of teaching, (2) their perception of why they went into teaching when disaggregated by the number of years of teaching, (3) their perception of the need for A/A male teachers, and (4) their perception of value and accomplishments as A/A male teachers in the classroom.

This study utilized a qualitative phenomenological design and was based upon Maslow’s (1970) hierarchy of needs …

Citizen-Informed Performance Measurement And Reporting In Local Government: Key Factors For Effective Democratic Governance, Eileen L. Pierce

Dissertations

Citizen engagement and performance measurement are concepts inherently in conflict with each other. Local government values citizen input and good governance. Simultaneously, the pressure of local government to be efficient and effective utilizing managerial techniques common in the private sector is intense. Due to challenges associated with the integration of performance measurement and active citizen involvement, initiatives in this area are sparse.

This study, using a mixed methods analysis, explored the research questions through examination of thirty-six units of local government that participated in the Alfred P. Sloan Foundation‘s Government Trailblazer Program. This program provided a unique opportunity for exploratory …

Preference Assessments For Older Adults With Dementia: Utility Of The Mswo Procedure And Assessment Of The Stability Of Preference, Paige B. Raetz

Dissertations

Individuals with dementia suffer from a variety of cognitive deficits that can lead to a lack of engagement in activities. In recent years, researchers have begun to look at ways to assess preferences in hopes that increased identification of leisure items may lead to increases in engagement. Due to the decline in cognitive status a simple questionnaire may not be sufficient to assess preference for this population. As a result, several recent studies have incorporated the use of systematic preference assessments to assess preference for leisure activities with adults with dementia using a paired stimulus format. The purpose of the …

Ductile Mode Material Removal Of Ceramics And Semiconductors, Deepak Ravindra

Dissertations

Ceramics and semiconductors are hard, strong, inert and lightweight. They also have good optical properties, wide energy bandgap and high maximum current density. This combination of properties makes them ideal candidates for tribological, semiconductor, MEMS and optoelectronic applications respectively. Manufacturing these materials without causing surface and subsurface damage is extremely challenging due to their high hardness, brittle characteristics and poor machinability. However, ductile regime machining of these materials is possible due to the high-pressure phase transformation occurring in the material caused by the high compressive stresses induced by the single point diamond tool tip. In this study, to further augment …

Becoming Formal Or Informal Entrepreneurs: How Institutions Matter, Joël Luc Raveloharimisy

Dissertations

This research explains the factors behind the variation of enterprise creation across countries by looking at the roles of formal and informal institutions and their interactions in the distribution of start-up enterprises in the formal and informal sectors. It tests two competing hypotheses about the individual versus mixed effects of formal institutions (measured by entry regulations) and informal institutions (measured by social capital) on entrepreneurship. The research uses quantitative analysis of data from 48 countries and a qualitative case study of Madagascar.

The findings from the quantitative and qualitative analyses are consistent regarding the independent effects of each set of …

Stability Of Popular R-Cbm Progress Monitoring Tools: Dibels® Next And Aimsweb®, Christine Russell

Dissertations

Currently there is no agreed-upon method for determining the difficulty level, referred to as the readability level, of Reading Curriculum-Based Measurement (R-CBM) passages. A key tenant of R-CBM is that the passages across each grade level are equivalent in difficulty level and therefore can be used to monitor student academic improvement. The primary objective in this study was to evaluate the homogeneity of oral reading fluency progress monitoring passages of two popular passage sets that are used frequently in schools. The purpose of this research was to examine the stability of each R-CBM progress monitoring passage set as well as …

Evaluating The Use Of A Self-Advocacy Strategy As A Means Of Improving Progress In The General Curriculum For Individuals With Cognitive Disabilities, Amy L. Schelling

Dissertations

The purpose of this study was to evaluate if the use of a self-advocacy strategy, with high school students identified as having a mild cognitive disability, would increase student use of self-advocacy skills across multiple school settings. Participants in the study were also identified as participating in at least one general education class at the time the study was conducted.

A multiple baseline across participants and across settings design was applied to determine the effects of instruction on students' use of a self-advocacy strategy before and after the instructional period and across settings. Use and generalization of a self-advocacy strategy …

Dosed Versus Prolonged Exposures: A Direct Comparison Of One-Session Treatments For Animal Phobias, Richard William Seim

Dissertations

It is widely accepted that for exposure-based therapies to be effective feareliciting stimuli must be presented continuously until there is a marked decrease in the client's anxiety (e.g., Eysenck, 1979; Foa & Kozak, 1986). However, an emerging body of research (cf. Seim, Waller, & Spates, 2010) suggests that a massed series of very brief exposures (< 150 sec) may be effective in the extinction of fear responses. The present study was designed to compare the efficacy and acceptability of two one-session treatments for animal phobias: one that utilized continuous, uninterrupted periods of exposure to a feared animal (Prolonged Exposures) and the other that utilized a massed series of brief (5-120 sec) exposure trials (Dosed Exposures). 24 adults (7 males, 17 females) between the ages of 18 and 57 years (M = 23.6) participated in this study. Each individual met DSM-IV criteria for a diagnosis of snake phobia or spider phobia. Participants were randomly assigned to one of two the two interventions. Both treatments required participants to gradually enter a room, approach, and eventually hold a live ball python or tarantula. Results from mixed model (between x within subjects) analyses of variance showed that the Dosed Exposure treatment performed equally well to Prolonged Exposures at decreasing behavioral avoidance, feelings of anxiety, perceptions of threat, and phobiaspecific cognitions from pre-treatment to post-treatment, and these gains were maintained at one-week follow-up. Although participants receiving Prolonged Exposures reported lower ratings of within-session anxiety, participants in the Dosed Exposure group had lower rates of treatment dropout, better compliance with procedures, and fewer safety-seeking behaviors during the treatment. These findings suggest that, contrary to popular belief, brief exposure trials can be effective in the extinction of phobic responses under certain conditions.

Contemporary Arab-American And Middle Eastern Women's Voices: New Visions Of "Home", Abdullah Kheiro A. Shehabat

Dissertations

esponding to an increase in the literary output of Arab-American and Middle Eastern women in the post September 1 ll Attacks, I examined three exemplary memoirs: Leila Ahmad's A Border Passage, Zainab Salbi's Between Two Worlds, and Marjane Satrapi's The Complete Persepolis. This study examines these memoirists' journeys back and forth from their homes of origin to their host homes in the West. In addition to charting how these memoirists break their silence and liberate themselves from authoritarian patriarchal culture and institutionalized religion, I discussed how they construct new feminist identities expressed through the creation of what …

Dissertations

The purpose of the current study was to help understand the lives, worldview, and meaning making of Soviet Holocaust survivors currently residing in the United States. Ethnographic interviews were conducted to explore survivor's childhood, family life, religion, political views, work, and social life. These areas were examined during the following time periods: pre-WWII, during WWII, and post-WWII.

From the collected and analyzed data I was able to offer an insight into the experiences of five Soviet Holocaust survivors under the Soviet regime. I described the struggles that the survivors experienced during the Holocaust, the losses they had suffered, and the …

Social Justice Advocacy And Counselor Education: A Study Of Counselor Educators' And Counseling Interns' Perceptions Of Social Justice Advocacy Training, Darryl C. Steele

Dissertations

Social justice and advocacy have become increasingly important topics in counselor training. The 2001 Council for the Accreditation of Counseling and Related Educational Programs (CACREP) training standards require counselor education programs to provide studies in social justice and advocacy processes. Moreover, 2009 CACREP standards stipulate that accredited programs must provide advocacy training specific to each specialty area. The American Counseling Association (ACA) adopted advocacy competencies, in part, to guide this training (Goodman, 2009; Lewis, Arnold, House, & Toporek, 2003). Despite training standards and frameworks such as the ACA Advocacy Competencies to help prepare students for advocacy, few studies have explored …

Characterizing Potential Sustainable Energy Feedstocks, Jesse George Thompson

Dissertations

Trap grease offers a promising and less expensive alternative to food grade vegetable oils for biodiesel production, but its commercial marketability could be affected by its intense and offensive odor. Identification, quantitation and eventual elimination of the odorant compounds are vital challenges that need to be addressed before commercialization can be achieved. A rapid method using HS-SPME and GC/MS was developed in this study to identify and quantify the major volatile odorant compounds present in trap grease. The main odorant compounds were identified as short chain free fatty acids (SC-FFA) from C₄ - C₁₀.

Assessing The Effects Of A Rectangular Rapid-Flashing Beacon On Vehicle Speeds Along A Four-Lane Divided Highway, Michelle Van Wagner

Dissertations

In 2008, nearly 31% of vehicle fatalities were related to failure to adhere to safe vehicle speeds (National Highway Traffic Safety Administration (NHTSA), 2009). Two studies were conducted to evaluate the effects of a Rectangular Rapid-Flashing Beacon (RRFB) triggered by excessive speed on vehicle speed using a combined alternating treatments and reversal design. Experiment 1 assessed the RRFB's impact on speeds as compared to baseline conditions only. Experiment 2 compared the RRFB to two standard beacon configurations. Both experiments were conducted at the same site during approximately the same time period and both employed the same data collection methodology. The …

Glucosamine-Induced Insulin Resistance In Primary Rat Hepatocytes And The Role Of Selenium As An Insulin Mimetic, Sandhya N. Adiyodi Veetil

Dissertations

Type 2 diabetes is mediated by insulin resistance, the inability of insulin to elicit a normal biological response in insulin responsive tissues. Several cellular models have been utilized to determine the mechanism of induction of insulin resistance but questions remain unanswered. One model, implicates the products of the Hexosamine Biosynthetic Pathway (HBP) in the induction of insulin resistance under hyperglycemia. The major end product of HBP, UDP-GlcNAc, is the substrate for O-GlcNAc transferase, an enzyme that catalyzes the O-GlcNAcylation of numerous proteins. This modification may play a role in induction of insulin resistance and thus needs to be evaluated in …

The Role Of Evaluations In Community Foundations, Brad R. Watts

Dissertations

Each year, U.S. community foundations are responsible for billions of dollars in philanthropy, yet the outcomes associated with these efforts often remain unknown. Previous research supports the importance of evaluating philanthropic activities and shows that community foundations express a strong interest in evaluation; however, the limited available evidence suggests that evaluation practice is still not widespread.

This study reports the findings from a national survey of community foundations on evaluation practice. The findings indicate that a substantial share of community foundations do not formally evaluate the outcomes of their philanthropic work. Additionally, although previous research has suggested that community foundation …
