Unitive/Mystical Experiences And Life Changes, Susan F. Schneeberger

Dissertations

The purpose of this study was to explore life changes in beliefs, philosophy, and behavior in individuals who reported having a unitive/mystical experience (U/ME). A U/ME is a generally spontaneously occurring state of consciousness characterized by a sense of unity or "oneness" that transcends sensory or cognitive apprehension (Stace, 1960). There is often an ineffable certainty that an ultimate truth has been perceived and can be applied to one's life. The experience may be accompanied or followed by feelings of joy and bliss. One hundred sixty adults from a broad range of demographic characteristics participated in a one-time webbased survey. …

The Culture Care Meaning Of Comfort For Ethnically Diverse Pre-Licensure Baccalaureate Nursing Students In The Educational Setting, Lynne K. Zajac

Nursing education is faced with the challenge of retaining ethnically diverse nursing students. Students who are ethnically diverse face unique challenges in addition to the universal stressors of nursing school. The experience of comfort as theorized by Kolcaba may provide ease, relief, and transcendence of the discomfort experienced by diverse nursing students. This ethnonursing research study utilizing Leininger's Culture Care Theory is an in-depth examination of the culture care meaning of comfort for ethnically diverse …

Proton Capture Reactions And Network Calculations On 46Ti, 64Zn, 114Sn And 116Sn Relevant To The Rp-Process, Ravin S. T. Kodikara

Dissertations

The rp-process makes an important contribution to the stellar nucleosynthesis by producing many of the light proton rich nuclei. Successive proton captures on seed nuclei followed by occasional β-decays and electron captures are the key features of this mechanism. For a detailed rp-process analysis, proton capture cross sections and reaction rates are essential. However, the lack of experimental data forces the researcher to largely depend on statistical model predictions.

This dissertation research is an attempt to investigate the proton captures of four particular nuclides; ⁴⁶Ti, ⁶⁴Zn, ¹¹⁴Sn and ¹¹⁶Sn. At Western Michigan University Van de Graaff …

In addition, teams in virtual communication environments will produce higher quality decisions and attain the assembly effect (synergistic decisions) less often than face-to-face teams on complex decision tasks. Mostly undergraduate students from business courses (N = 358) completed the NASA Survival Exercise complex decision task first individually, …

"I Unsex'd My Dress": Lord Byron's Seduction Of Gender In "The Corsair", "Lara", And "Don Juan", Alexis Spiceland Lee

Dissertations

The goal of this project is to posit a theory of how Byron’s texts, specifically through the development of his hero, construct gender and sexuality as styles of seduction that resist easy classification by binary systems. I propose that Byron’s works characterize gender through ironic performances of seduction that, because they reveal that binary structures lack a stable core, dissolve systemic differentiation and thus fatally complicate any attempt to force the individual into rigid categories of gender or sexual identity. Byron’s works deploy seduction as a tactic of ironic representation of both gender and sexual practice that is necessarily multiplicitous …

A Comprehensive Uncertainty Analysis And Method Of Geometric Calibration For A Circular Scanning Airborne Lidar, Michael Oliver Gonsalves

Dissertations

This dissertation describes an automated technique for ascertaining the values of the geometric calibration parameters of an airborne lidar. A least squares approach is employed that adjusts the point cloud to a single planar surface which could be either a narrow airport runway or a dynamic sea surface. Going beyond the customary three boresight angles, the proposed adjustment can determine up to eleven calibration parameters to a precision that renders a negligible contribution to the point cloud’s positional uncertainty.

Presently under development is the Coastal Zone Mapping and Imaging Lidar (CZMIL), which, unlike most contemporary systems that use oscillating mirrors …

Despite ongoing efforts of the federal and state government, as well as those of the local school districts, this problem continues to burden the educational system and society as a whole. The opinions of those with the experience of dropping out and returning to school are pertinent sources of information on educative practices that can help stem the dropout rate.

A survey was conducted to gather the opinions of students …

Administrators' And Teachers' Perceptions Of In-School Suspension, Amelia Shondra Jackson

Dissertations

Providing a safe and orderly school environment for students to learn is of paramount importance to school administrators, teachers, students, and the general public; however, the learning process should not be compromised while trying to maintain such an environment. There are many alternative approaches that can be utilized that would rectify the problem we as educators face in providing a safe and orderly environment. At-risk students are usually the ones who have the most serious infractions. These students exhibit a cyclical pattern of recalcitrant behavior. It is imperative that these at-risk students be identified as early as possible, and intervention …

Emotional Maturity Of Adolescents And Adults In Ged Programs, Billy Joe Riffle

Dissertations

When discussing issues relating to students in General Educational Development (GED) Option and pre-GED programs with educators, the contention exists that it is possible to make reasonably accurate predictions on the success or failure of a student by observing a number of items. Looking at their cumulative records shows their academic and attendance history. Insight is gained by looking at their family dynamics and how they relate to adults. Much can be learned about them from their discipline reports and the nature of any infractions. One of the most intriguing aspects gained through experience and observation is the perception of …

Stereo Matching Using A Modified Efficient Belief Propagation In A Level Set Framework, Stephen Goyer Rogers

Dissertations

Stereo matching determines correspondence between pixels in two or more images of the same scene taken from different angles; this can be handled either locally or globally. The two most common global approaches are belief propagation (BP) and graph cuts.

Efficient belief propagation (EBP), which is the most widely used BP approach, uses a multi-scale message passing strategy, an O(k) smoothness cost algorithm, and a bipartite message passing strategy to speed up the convergence of the standard BP approach. As in standard belief propagation, every pixel sends messages to and receives messages from its four neighboring pixels in EBP. Each …

Folate Receptor-Targeted Delivery Of Small Interfering Rna To Cancer Cells, Yilin Zhang

Dissertations

The vitamin folic acid (folate, FA) has been extensively explored as a targeting ligand to deliver a variety of diagnostic/prognostic/therapeutic agents into various tumors through the assistance of its receptor – the folate receptor (FR). FR is over-expressed in many types of human cancer and can mediate internalization of FA-conjugates through an endocytic pathway. The discovery of small interfering RNA (siRNA), which is cable of inducing potent gene silencing in a sequence-specific manner, provides an excellent molecular tool to suppress aberrant gene expression in malignancies, and therefore siRNA has the potential to revolutionize cancer therapeutics. Towards the goal of developing …

A Psychometric Investigation Of The Young Adult Social Behavior Scale (Yasb), Michelle Rene Augustin

Dissertations

Aggressive behavior is a serious public health concern that has resulted in several problems in contemporary society. Despite a considerable body of literature on human aggression, both popular and scientific, a focus on overt physical aggression has obscured other forms of aggression. As a result, considerably less is known about other, more subtle forms of aggression, such as relational aggression. Moreover, research on relational aggression, particularly among older adolescents and adults, has been hindered by the lack of psychometrically sound measures. Research in this area would be enhanced by the availability of such a measure, facilitating comparison of data across …

Geological And Ichthyological Investigations Into Palaeodrainage Hypothesis For The Tennessee River, Andrea Karen Persons

Dissertations

The course of the ancestral Tennessee River has been debated in both the geological and biological literature for over 100 years. Several of the proposed courses for the ancestral Tennessee place its course across the state of Mississippi. Geochemical analysis of sedimentary rocks in the Pascagoula River basin supports these hypotheses suggesting that the rocks in the Pascagoula basin were derived from the Highland Rim of Tennessee and northern Alabama, while geochemical analysis of rocks from the Pearl River basin point to deposition from a mixture of sources including the ancestral Mississippi River and perhaps the ancestral Tennessee. To delve …

Regulation Of Biofilm And Antibiotic-Resistance By The Modulator Of Sara (Msa) In Staphylococcus Aureus, Antony Schwartz

Dissertations

Staphylococcus aureus is an important human pathogen that is the causative agent of life-threatening diseases such as endocarditis and osteomyelitis. The ability of S. aureus to thrive as a successful pathogen can be partially attributed to its ability to form biofilm. Biofilm is an extracellular polysaccharide, protein, and DNA-based slime layer that protects the bacterial community. The global regulator sarA is essential for biofilm formation. Since the modulator of sarA (msa) gene regulates several virulence factors and is required for the full expression of sarA, the capacity of the msa mutant to form a biofilm was examined. The mutation of …
