Gender And Ovarian Hormone Effects On The Relative Contribution Of Chromaticity To Brightness, Brian Keith Foutch

Dissertations

PURPOSE: The chromatic contribution to brightness perception was compared in males and females. METHODS: Direct brightness matching (DBM) and heterochromatic flicker photometry (HFP) were used to measure relative luminous efficiency, and DBM/HFP ratios were predicted to be higher for females than males on repeated measures and for each "primary" color. No gender differences were predicted in DBM or HFP measures. Within-females effects of estradiol (E2) and progesterone (PG) levels, contraceptive use, and menstrual cycle phase were also investigated. It was expected that E2 would directly predict DBM/HFP ratios and that PG would antagonize that relationship. Based on that prediction, DBM/HFP …

An Examination Of Body Objectification And Social Physique Anxiety In Women And Men: The Priming Effects Of Anticipating A Brief Social Interaction, Erin Renee Barnett

Dissertations

Body objectification occurs when individuals adopt an observer’s view of their body and treat their body as an object. This process has been linked to a host of harmful consequences, including appearance anxiety and shame, decreased awareness of internal bodily states, eating disorders, depression, and sexual dysfunction (see Fredrickson & Roberts, 1997, for a review). The current investigation is based on objectification theory (Fredrickson & Roberts, 1997), a sociocultural framework that describes the experiences and psychological risks of those who objectify their bodies. This study examined trait levels of self-objectification and social physique anxiety in women and men, as well …

The Effects Of Early Reading Interventions On Student Reading Levels And Achievement, Theresa F. Arnold

Dissertations

The purpose of this study was to investigate the academic impact of reading interventions provided to kindergarten through third grade students identified as at-risk for reading failure. Studies have indicated that educators become very concerned when the number of elementary students who struggle with reading increase. It is difficult for students to reach grade level reading expectation when they have a poor start at learning to read. The gap between these children and children who read well widens as they progress through the grade levels. The research questions included 1) What gains are seen in reading abilities for children who …

Contextual Factors Influencing The Acute Care Registered Nurse's Response To Clinical Alarms, Kathleen Mary Stacy Phd

Dissertations

Nurses are faced with a multitude of clinical alarms on a daily basis. There is an inherent expectation that upon hearing an alarm the nurse will immediately respond to assess the situation and initiate appropriate action to correct the problem. Yet this does not always occur. Issues with alarm responsiveness can pose a serious threat to patient safety. The purpose of this qualitative study was to develop a broader understanding of the contextual factors that influenced the acute care nurse's response to clinical alarms. This study used an interpretive phenomenological methodology to study the lived experiences of the nurses who …

Maternally Derived Antibodies In Avian Eggs And Offspring: Ecology, Life History, And Development, Brianne Ashley Addison

Dissertations

Mothers can alter offspring phenotypes through a variety of indirect effects, including the deposition of nutrients, hormones, and defense proteins in to the egg. Defense proteins, and antibodies in particular, may be tremendously important for neonatal defense against pathogens and the direction of resources into growth rather than immune responsiveness. Moreover, maternally derived immunoglobulins have been proposed to have an imprinting effect on the development of humoral immunity. In my dissertation, I explored a variety of ecological, life history, and developmental factors that could contribute to the evolution of yolk antibody allocation in a variety of avian species. In the …

Comparison Of The Trauma Symptom Checklist For Children, Ucla Ptsd Index, And Child Behavior Checklist In Children With A Trauma History, Melissa Verish Broome

Dissertations

The purpose of this dissertation was to study a host of PTSD assessment-related problems in children with a trauma history (N = 110) who were seeking treatment at a community mental health clinic. Exploratory factor analyses using the trauma-related and non-trauma-related subscales on the Child Behavior Checklist (CBCL; Achenbach 1991), UCLA PTSD Index (Pynoos 1998), and the Trauma Symptom Checklist for Children (TSCC; Briere 1996) were conducted. Results indicated that in children aged 7 to 11, but not in older children aged 12 to 17, the UCLA PTSD Index and the TSCC trauma-related scales formed a trauma factor. The CBCL …

Processing Techniques For Partial Tree-Pattern Queries On Xml Data, Pawel Placek

Dissertations

In recent years, eXtensible Markup Language (XML) has become a de facto standard for exporting and exchanging data on the Web. XML structures data as trees. Querying capabilities are provided through patterns matched against the XML trees. Research on the processing of XML queries has focused mainly on tree-pattern queries. Tree-pattern queries are not appropriate for querying XML data sources whose structure is not fully known to the user, or for querying multiple data sources which structure information differently. Recently, a class of queries, called Partial Tree-Pattern Queries (PTPQs) was identified. A central feature of PTPQs is that the structure …

High Resolution Solar Observations From First Principles To Applications, Angelo P. Verdoni

Dissertations

The expression "high-resolution observations" in Solar Physics refers to the spatial, temporal and spectral domains in their entirety. High-resolution observations of solar fine structure are a necessity to answer many of the intriguing questions related to solar activity. However, a researcher building instruments for high-resolution observations has to cope with the fact that these three domains often have diametrically opposed boundary conditions. Many factors have to be considered in the design of a successful instrument. Modern post-focus instruments are more closely linked with the solar telescopes that they serve than in past. In principle, the quest for high-resolution observations already …

Probing The Complex Magnetic, Electronic And Structural Properties In Correlated Manganese Oxides, Peng Gao

Dissertations

Rare-earth Manganese Oxides (RMnO₃) exhibit two distinct structural phases: the orthorhombic structure and the hexagonal structure. The doped orthorhombic phase exhibits a metal to insulator transition, charge ordering and a strong response of electron transport properties to magnetic fields (colossal magneto-resistance). At low temperatures, this system may also exhibit a finite polarization which couples to external magnetic fields. The hexagonal phase is known to have a large spontaneous polarization at high temperatures which couples to the low temperature magnetic order. These materials are important from the basic point of view of understanding strong electronic correlations and …

Retention, Social Promotion, And Dropout Rates In Mississippi, Jennifer Jo Woodruff

Dissertations

There has been much research in the past two decades about the dropout problem in America. Dropout rates have become a focal point for all public schools in the nation largely due to components of the No Child Left Behind Act and the Dropout Prevention Act that associate monetary rewards to schools that raise the graduation completion rates to 90%. The dropout rates for the United States rank the educational system 17th for graduation completion rates among developed countries. Mississippi has repeatedly earned the title of low-ranking among all states in the nation.

Dropping out of high school is followed …

A Cross-Cultural Study Of Intergenerational Communication In Workplace, Yan Guan

Dissertations

This study investigates intergenerational relationships in organizational settings and uses Communication Accommodation Theory (CAT) to examine the influence of age, power, culture, and self-construal on young workers' perceptions of intergenerational communication. According to CAT, communication is stereotypical due to outgroup bias, people favor their own age or power group more than other age or power groups. CAT research showed that young Asians' perceptions of intergenerational communication may be more negative than their Western counterparts. Self-construal was studied to understand the nature of culture's influence. Research and theory supported nine hypotheses and three research questions.

A study using self-report measure was …

Using a qualitative grounded theory approach, this study examined the change in attitudes and behaviors of K-8 principals who participated in a Group Relations Conference. A grounded theory approach was employed to address the following research questions: How do principals understand and describe their learning after participating in a Group Relations Conference? How do they apply their …

More Power To You: Parental Experiences With The Public School Choice Option Provided By The No Child Left Behind Act Of 2001, Roslyn Williams Woodard Edd

Dissertations

The No Child Left Behind Act (NCLB) of 2001 was the federal government's commitment toward providing an equitable education for all students. Recognizing the impact parents had on the academic achievement of their children, provisions for increased parental involvement were emphasized, especially when children attended low achieving schools. One way parents could exercise their newfound power to improve their children's educational experience was to use the federal policy's public school choice option to enroll them into higher performing schools which met or exceeded NCLB standardized testing goals. This study examined the experiences parents and their middle school aged children had …

A Psychometric Evaluation Of The Revised Optimism-Pessimism Scale Of The Mmpi-2, Ginger Burge Debrule

Dissertations

The present study tested the psychometric properties of the Revised Optimism-Pessimism Scale (PSM-R) of the MMPI-2. This scale purportedly measures the respondent's explanatory style on a dimension of optimism and pessimism. Participants included 92 college undergraduates and 2,729 participants from archived outpatient data. The PSM-R is a reliable measure, based on test-retest reliability and internal consistency. However, the construct validity of the measure is questionable. Evaluation of the PSM-R items suggests that the items are not all related to the optimism-pessimism construct. In addition, convergent validity of the PSM-R was assessed using measures of attributional style, dispositional optimism, hope, depression, …

The Effects Of Differential Negative Reinforcement Of Task Engagement On Escape From Academic Tasks, Brett Vivian Mehrtens Prince

Dissertations

The effects of differential negative reinforcement of alternative behavior (DNRA) were examined on the escape behavior of four 1st and 2nd grade general education students. The alternative behavior that was negatively reinforced was task engagement during reading or math periods. The DNRA treatment was evaluated for its effects on task engagement in either a DNRA with access to a preferred activity condition or a DNRA without access to a preferred activity condition. In the preferred activity condition, the participants were allowed to engage in a high preferred activity when they had been engaged with an academic task for a certain …

Creative Metacriticism: The Portrayal Of Literary Theory In Contemporary Fiction, Zaydun Ali Al-Shara

Dissertations

Some modern creative writers have shown a talent not only in writing tales, but also in philosophy and theory as they examine questions and problems in fiction-making and the very act of reading. This dissertation examines the role the metafictive novel plays in the development of literary theory and fiction. I explore how writers of this type of novel emerge as creative metacritics who overtly and/or covertly, through their fiction, respond to and critique literary theory. The inquiry examines the reciprocal relationship between the fiction of creative metacritics and important movements in literary theory in the late 20th Century. All …

A Conceptual Integration Analysis Of Multiple Instructional Metaphors, Robert Johnson

Dissertations

The present study was conducted to investigate some of the practical implications of conceptual integration theory for educators. This research was a mixed-methods study exploring how improvements in understanding—learning—(as measured by a selectedresponse assessment) are reflected in changes in learner language (described in terms of conceptual integration patterns). After a pretest with open-response and selected-response prompts, two groups of young adult participants viewed different videos of a slightly different review lesson in genes, genetics, and heredity, the difference lying in two different metaphor conditions: the experimental group was shown a more “metaphorrich” version of the lesson using two classic metaphors …

Analytical, Computational And Experimental Studies Of Capillary Flow In Complex Geometries, Yongqing Peng

Dissertations

The dynamic processes of capillary flow in complex geometries have been studied analytically, computationally and experimentally in this research. A general approach for modeling the capillary flow in arbitrary irregular geometries with straight axis of symmetry is proposed. Using this approach, the governing equation to describe the dynamic capillary rising motion in capillaries with nonuniform elliptical cross-section is first derived under the assumptions of parabolic distribution of the axial velocity and constant contact angle. The calculation results for the capillary flow in different tubes with irregular wall show that, in comparison with existing models that have been tested, the present …

Dissertations

The purpose of this study was to assess, plan, and implement a budget building process through collaboration with the stakeholders of a targeted school district. The research question of this study was, “Will allowing the stakeholders more input, autonomy, and collaboration during a budget building process build a team environment and ultimately ownership in managing their perspective budgets?” The culture and attitudes of stakeholders were pessimistic towards the senior administration. There seemed to be a feeling of mistrust concerning the budget and allocations. Action research methodology was conducted, while applying Andragogical principles with the members of the district. This process …

Computing For Knowledge Management: From Nonaka To Visualisation And Knowledge Maps, Helmut Huber

Dissertations

Management itself is not always clearly understood, however, the confusion can be sorted if the underlying theory is clearly distinguished from its implementations. There also may be a specific role for computing in Knowledge Management. It is suggested that Knowledge Management technologists seek a unique strategic position for Computing in Knowledge Management, for reasons of clarity and differentiation from Information Systems. The effective transfer of knowledge is one of the main themes or core competency in Knowledge Management. This is also one of the areas where Knowledge Management technologists may find the niche for a distinct and unique contribution the …
