Patterns Of Relationship Satisfaction And Sexual Behavior As A Function Of Pornography Use Among College Men, Joel David Deloy

Theses and Dissertations

Recent research on sexually explicit materials (SEM), or pornography, has expanded from a focus on sexual violence, and aggression, towards the examination of the influence of SEM on other relationship factors. Available information on how males involved in a romantic relationship use SEM has been limited, and the effect of SEM use on relationship satisfaction and sexual behavior is not well understood. This study examined 245 college men who completed self-report measures of relationship satisfaction, core relationship variables (autonomy, affection, conflict resolution, intimacy, and equality) and SEM use patterns. All participants were in significant romantic relationships of at least three …

Predictors Of Change In Health Care Use After Marital And Family Therapy, Scott H. Payne

Theses and Dissertations

The cost of health care continues to increase. Based on the biopsychosocial model of heath care, it has been shown that the treatment of psychological and social problems can have a cost offset effect on the cost of medical care. While this offset effect has been shown in an MFT population, there are no known studies that have looked at predictors of the change in medical use by those that receive marital and family therapy. This study looked at psychological and social measures of individuals who received marital and family therapy. These measures were evaluated based on the change from …

The Influence Of Membrane Lipid Order On Cell Shape And Microvesiculation In Human Erythrocytes, Laurie Jackson Gonzalez

Theses and Dissertations

Exposure of human erythrocytes to elevated intracellular calcium causes alterations in cell shape and stimulates shedding of the cell membrane in the form of microvesicles. We hypothesized that both the shape transition and microvesiculation are influenced by microscopic membrane physical properties such as lipid order. To test this hypothesis, membrane properties were manipulated by varying the experimental temperature, membrane cholesterol content, and the internal ionic environment. Changes in membrane order were assessed using steady-state fluorescence spectroscopy with an environment-sensitive probe, laurdan. Our observations led us to the following conclusions: 1) the modest temperature dependence of membrane structure observed with laurdan …

Understanding The Other Side: The Traits Of Partners Of Individuals With Neurotic Traits In Committed Premarital Relationships, Ryan W. Blick

Theses and Dissertations

The purpose of this study was to identify the partners' traits and skills that predict relationship satisfaction in committed, premarital relationships in which one person has neurotic traits, as well as to examine the degree of consensus about neuroticism for both individuals. Data from 198 never-married, young adult, premarital couples who had completed the RELATionship Evaluation (RELATE) questionnaire were used in the analyses. Measures of perceived partner traits and skills included levels of empathic communication, clear sending, flooding, kindness, flexibility, criticism, and contempt and defensiveness. Relationship satisfaction as measured by RELATE was the criterion variable. Results showed little agreement between …

Beliefs And Values Of K–12 Teachers Underlying The Grading Process In North Dakota Small Rural Schools, Keith H. Gustafson

Theses and Dissertations

Research has shown that the grades teachers assign to students have been increasing in value, whereas the achievement measured by the grades has remained the same. There is great variability reported in the current literature concerning the grading practices of teachers. There is no consensus about what grades should mean, what reference base should be used for comparability, or the extent to which the grades assigned should correlate with the students' performances on national achievement tests. The purpose of the study was to gather information about general education teachers' beliefs and values regarding the criteria that should be used in …

Laboratory -Induced Aggression Among Participants With And Without A History Of Alcohol -Related Aggression, Matthew D. Bailly

Theses and Dissertations

The effects of alcohol-related and mixed alcohol and non-alcohol-related histories of aggression on aggressive responding in the laboratory were investigated using the Point Subtraction Aggression Paradigm (PSAP). Forty-five male college students were selected for participation in the present study using a questionnaire consisting of modified items from the Buss-Durkee Hostility Inventory (BDHI; Buss & Durkee, 1957) and Overt Aggression Scale (OAS; Yudofsky et al., 1986) that allowed for assignment to an alcohol-related, mixed, or no history of aggression control condition. Participants performed four 25-minute PSAP sessions in sequence during one laboratory visit. The short version of the Minnesota Multiphasic Personality …

Social Anxiety And The Recognition Of Auditory And Visual Emotional Cues, Ryan D. Hartmann

Theses and Dissertations

Cognitive theory attributes social anxiety to a host of perceptual biases that transform harmless interpersonal stimuli into threats. Socially anxious college students were expected to misinterpret visual and auditory cues of emotion in others more readily than their more confident counterparts. This group of socially anxious men and women were also expected to perceive negative emotion from visual and auditory cues that were determined to be neutral or positive through an external validation process. A total of 16 participants were assigned into each of the four cells of this 2 (gender) by 2 (Liebowitz Social Anxiety Scale-Self Report median split) …

Expanding Roles: Paraeducators Providing Health Care To Students In Elementary Schools, Sharon Nelson

Theses and Dissertations

Approximately ten to thirty percent of school aged children have a chronic physical, developmental, behavioral or emotional condition that requires specialized health care and related services. Providing the needed health care is critical in maintaining students' participation and success in school. The enactment of PL 94-142, in 1975, mandated that public schools give children with disabilities the right to a "free and appropriate public education" in the least restrictive environment possible. School nurses are the logical choice to provide the necessary health care in schools. They have the knowledge, expertise, judgement and critical thinking skills inherent in nursing education and …

Willa Cather: Male Roles And Self-Definition In My Antonia, The Professor's House, And "Neighbor Rosicky", Kristina Anne Everton

Theses and Dissertations

Gender roles are a tool used by society to set acceptable boundaries and ideals upon the sexes, and during the early part of the twentieth century in America those gender boundaries began to blur. As a result of the 19th Amendment, men must have felt their decreasing importance because women were no longer solely dependent upon them, and gender roles shifted as woman began to occupy territory that was traditionally held by men. The “New Woman" entered the workforce, and refused to accept traditional female gender conventions. In response to the “New Woman," Theodore Roosevelt and other leading males sought …

Understanding Psychological Control Through Differences Between Shame And Disappointment: Implications For Childhood Agression, Sacha Leah Bikhazi

Theses and Dissertations

The purpose of this study was to examine the potentially unique roles that parental use of two psychological control dimensions, shame and disappointment, play in predicting children's relational and physical aggression. It was additionally of interest to investigate whether warm/involved parenting would moderate the effects of these forms of psychological control on both types of childhood aggression. Based on a review of literature, it was hypothesized that parental use of shame would positively predict aggression in children, whereas parental use of disappointment would not be significantly associated with childhood aggression. Additionally, it was hypothesized that warm, involved parenting would have …

Capillary Electrophoresis Of Proteins With Selective On-Line Affinity Monoliths, Jenny Marcela Armenta Blanco

Theses and Dissertations

The analysis of proteins in biological fluids by capillary electrophoresis (CE) is of interest in clinical chemistry. However, due to low analyte concentrations and poor concentration limits of detection (CLOD), protein analysis by this technique is frequently challenging. Coupling preconcentration techniques with CE greatly improves the CLOD. An on-line preconcentration-CE method that can selectively preconcentrate any protein for which an antibody is available would be very useful for the analysis of low abundance proteins and would establish CE as a major tool in biomarker discovery. To accomplish this, an on-line protein G monolithic preconcentrator CE system for enrichment and separation …

Defining The Components Of Academic Self-Efficacy In Navajo American Indian High School Students, Thomas R. Golightly

Theses and Dissertations

The academic difficulties experienced by a majority of Navajo American Indian students are well documented. Past research has focused on a variety of internal and external factors which possibly explain some of these difficulties. Low levels of academic self-efficacy (ASE) has been identified as one of the factors possibly contributing to lower than expected rates of academic achievement and low post-secondary education retention rates in this population. This investigation sought to further define the component structures of ASE using theoretical structures postulated by Bandura (1977a, 1997), namely: past success, modeling, verbal persuasion, and emotional arousal. Information about grade point averages …

Modeling And Data Analysis Of Conductive Polymer Composite Sensors, Hua Lei

Theses and Dissertations

Conductive polymer composite sensors have shown great potential in identifying gaseous analytes. To more thoroughly understand the physical and chemical mechanism of this type of sensors, a model was developed by combining two sub-models: a conductivity model and a thermodynamic model, which gives a relationship between the vapor concentration of analyte(s) and the change of the sensor signals. In this work, 64 chemiresistors representing eight different carbon concentrations (8–60 vol.% carbon) were constructed by depositing thin films of a carbon black–polyisobutylene composite onto concentric spiral platinum electrodes on a silicon chip. The responses of the sensors were measured in dry …

Changing Nature: Globalization And Economic Reforms In Brazil, Lucas Gimenes Loureiro

Theses and Dissertations

Globalization is affecting our lives in ways that we never expected before. Greater interdependence, some scholars argue, weakens the ability of nation-states to retain their authority over individuals and corporations. However, nation-states are highly adaptable and they have the power to maintain their primacy .

Governments have the ability to choose which model of development their economies should pursue. Thus, based on the choice of economic model, nation-states shape their economies and the way business operates within it. In other words, governments will essentially steer their economies in a certain direction, even though they cannot determine the exact path that …

Studies On Cyclooxygenase-1, Its Structure And Splice Variants, And Modulation Of Cyclooxygenase-2 By Inducible Nitric Oxide Synthase And Novel Phytochemicals., Yibing Xu

Theses and Dissertations

Cyclooxygenases (COXs) are of important therapeutic value as they are the target site of aspirin-like drugs. Here I report nine new COX-1 splice variants in chapter 1, which I characterized with regard to heme-binding and other properties. Inducible NO synthase (iNOS) and cyclooxygenase-2 (COX-2) are co-inducible in many tissues following mitogenic and proinflammatory stimulation. In chapter 2, I investigate the physical and enzymatic properties of human COX-2 and iNOS and demonstrate that, despite reports to the contrary by another laboratory, they do not interact. The only reported COX-1 splice variant to exhibit cyclooxygenase activity has been isolated from …

Behavior Problems In Children Of Battered Women, Stacey Monahan

Theses and Dissertations

The purpose of this study was to address this question: Is there a relationship between the trauma symptoms of mothers and the behavior problems of their children in the context of domestic violence? Mothers' trauma symptoms significantly correlated with their children's behavior problems in these children between the ages of 3 to 10 years. Pearson correlations revealed that the mothers' defensive avoidance scale scores significantly correlated with their children's anxious/depressed and internalizing scale scores, mothers' depression and impaired self-reference scale scores significantly correlated with their children's withdrawn and internalizing scale scores, and mothers' dysfunctional sexual behavior and tension reduction behavior …

Fault And Defect Tolerant Computer Architectures: Reliable Computing With Unreliable Devices, George R. Roelke Iv

Theses and Dissertations

This research addresses design of a reliable computer from unreliable device technologies. A system architecture is developed for a "fault and defect tolerant" (FDT) computer. Trade-offs between different techniques are studied and yield and hardware cost models are developed. Fault and defect tolerant designs are created for the processor and the cache memory. Simulation results for the content-addressable memory (CAM)-based cache show 90% yield with device failure probabilities of 3 x 10(-6), three orders of magnitude better than non fault tolerant caches of the same size. The entire processor achieves 70% yield with device failure probabilities exceeding 10(-6). The required …

How Does The Political Nature Of The Defense Acquisition Process Affect Cost Growth, Nikolaos Gounatidis

Theses and Dissertations

Many of the major programs of the DoD are experiencing cost growth. This research developed an empirical model in order to explain cost overruns. This thesis sought to discover relationships between cost overruns and factors that originate from the political nature of the defense acquisition process. The model describes how the political and legislative balances of power between the parties of the Congress, the change of the purchase habits of the DoD from production to service contracts, and the spreading of defense manufacturing capacity across the U.S are related to cost overruns. This research studied 193 programs from 1970 to …

Factors And Interactions That Affect Air Force C-17 Aircraft Mission Capable Rates, Scotty A. Pendley

Theses and Dissertations

Given the high demand for mission capable airlift aircraft and considering increasing budget pressures, Air Mobility Command decision makers need a better understanding of mission capable (MC) rate-related factors and their interactions for mobility aircraft. This is needed to comprehend how issues such as airlift funding, current and future force reductions, and manning and experience levels may impact future MC rates for air mobility assets. Existing tools do not incorporate several key variables that the literature suggests are related to MC rates. Using a longitudinal approach, this thesis combines C-17 aircraft data with a structural equations modeling approach to evaluate …

Laser Covariance Vibrometry For Unsymmetrical Mode Detection, Michael C. Kobold

Theses and Dissertations

Simulated cross - spectral covariance (CSC) from optical return from simulated surface vibration indicates CW phase modulation may be an appropriate phenomenology for adequate classification of vehicles by structural mode. The nonlinear structural to optical relationship is close to unity, avoiding nulls and high values; optical return contains sufficient spectral ID information necessary for data clustering. The FE model has contact between the homogeneous rolled armor and vehicle hull, a simple multi - layer skin model typical of most vehicles. Most of the high frequency energy moved to lower frequencies. This nonlinearity segments contact vibration modes into two classes: symmetrical …

Multilingual Phoneme Models For Rapid Speech Processing System Development, Eric G. Hansen

Theses and Dissertations

Current speech recognition systems tend to be developed only for commercially viable languages. The resources needed for a typical speech recognition system include hundreds of hours of transcribed speech for acoustic models and 10 to 100 million words of text for language models; both of these requirements can be costly in time and money. The goal of this research is to facilitate rapid development of speech systems to new languages by using multilingual phoneme models to alleviate requirements for large amounts of transcribed speech. The Global Phone database, winch contains transcribed speech from 15 languages, is used as source data …

Detection Of Proteins By Two-Photon Excitation Of Native Fluorescence, Li Li

Theses and Dissertations

Proteins are of primary importance to the structure and function of all living cells. Study of proteins relies on the ability to separate a complex mixture so that individual proteins can be more easily processed by other techniques. Since protein samples often exist at low concentration in a small volume, the trend in chemical analysis is toward micro total analysis systems (µTAS) or lab-on-a-chip devices. Among µTAS separation methods, the relatively new electric field gradient focusing (EFGF) technique has shown potential. It focuses and separates analytes based on their electrophoretic migration in an opposing hydrodynamic flow. The detection principles that …

Construction Of A Col11a1 Transgene Vector, Cameron Mckell Beck

Theses and Dissertations

Background: Cartilage disorders affect millions of people in the United States alone, with effects ranging from poor skeletal development and joint pain to shortened lifespan and perinatal lethality. Many of these disorders have their root in defects of collagen, type XI collagen being among the most important. A mouse model of such a type XI collagen defect is the chondrodysplasia (cho) mutant. Mice homozygous for this null mutation in the Col11a1 gene do not express the α1 chain of type XI collagen. This results in a functional knockout of type XI collagen, leading to insufficient skeletal development and perinatal lethality. …

The Effects Of Wearing A Cooling Vest During The Warm-Up On Long Distance Interval Training, Andrew Robert Tegeder

Theses and Dissertations

Purpose: Reducing body temperature before exercise is called precooling. Past research suggests that reducing body core temperature (Tc) slightly can result in improved running performance. This study evaluated the effects that warming up, while wearing a cooling vest prior to an interval workout, had on Tc, and interval time in long-distance runners. Methods: Nineteen healthy male collegiate cross-country runners were recruited for this study. Each subject warmed up and exercised under two different conditions: (a) an experimental condition in which subjects wore a Nike PreCool® ice vest during warm-up and (b) a control condition. Subjects performed a warm-up followed by …

Feedback Applications In Active Noise Control For Small Axial Cooling Fans, Matthew J. Green

Theses and Dissertations

Feedback active noise control (ANC) has been applied as a means of attenuating broadband noise from a small axial cooling fan. Such fans are used to maintain thermal stability inside of computers, projectors, and other office equipment and home appliances. The type of low-level noise radiated from axial cooling fans has been classified as harmful to productivity and human well being. Previous research has successfully implemented feed-forward ANC, targeting specific narrow-band fan noise content related to the blade passage frequency (BPF) of the fan. The reference signal required for a feed-forward algorithm limits its ability to attenuate much of the …

Laryngeal-Level Amplitude Modulation In Vibrato, Lorie C. Reese

Theses and Dissertations

Research in vocal vibrato has established that vocal tract filtering is primarily responsible for the amplitude modulation (AM) present in Western classical vibrato. Using electroglottography (EGG) and the EGG speed quotient, which is sensitive to fluctuations in the amplitude of vocal fold vibration, AM was detected at the laryngeal (source) level, in addition to the subsequent AM which results from vocal tract filtering. Seventeen classically-trained opera singers sang vowels in three pitch and loudness conditions. EGG and microphone measurements of FM and AM and their rates, extents, and periodicity were made. Airflow was also measured, and the samples were rated …
