A Quantitative Study Of The Effectiveness Of Positive Behavior Support In Secondary Schools, Rebecca Lynn Raftery

Theses and Dissertations

This study was conducted to evaluate the long-term effectiveness of a second tier intervention on at risk students' behaviors and academic success. The study included 113 middle school and junior high students identified as being at risk for emotional and behavioral disorders using the Systematic Screening for Behavior Disorders (SSBD). The participants were assigned to a control group (no treatment), one, two, or three semesters of the intervention. The intervention integrated components of social skills instruction, self-management techniques, and social and emotional awareness. Students' behaviors and academic success were measured using school data (i.e. GPA, Office Discipline Referrals, attendance, and …

A Reassessment Of James Joyce's Female Characters, Anna Margaretha Gordon

Theses and Dissertations

The female characters in James Joyce's fiction have received considerable critical attention since the publication of his writings and are often denigrated as misogynist portrayals of women. However, a textual and historical analysis of the female characters in A Portrait of the Artist as a Young Man, Dubliners, Ulysses, and Finnegans Wake shows them in a more constructive light. Such an analysis reveals them to be sympathetic portrayals of the situation of Irish women at the turn of the twentieth century. An historical contextualization of the characters is essential in any reading of Joyce, but is particularly important for his …

Cortisol Response Of Non-Suicidal Self-Injurers Versus Non-Self-Injurers Exposed To A Social Rejection Laboratory Stressor, Patrick L. Kerr

Theses and Dissertations

Non-suicidal self-injury (NSI) represents a growing area of concern in a variety of clinical settings, yet remains a poorly understood phenomenon. An influx of research on the functions of NSI over the past decade has suggested a biopsychosocial emotional regulation model of this behavior. This model proposes that self-injurers engage in NSI to reduce negative emotions, and presupposes that self-injurers are characterized by emotional dysregulation. The present study evaluated the biological component of this model by assessing hypothalamic-pituitary-adrenocortical axis (HPAA) functioning in a group of self-injurers(n=26) and non-injuring healthy controls (n=28). HPAA functioning was assessed via measuring salivary cortisol levels …

Sixty percent of the bluegill successfully transformed E. chipolaensis glochidia into juvenile mussels while 80% of the redbreast sunfish were successful.

Constituent Order And Participant Reference In Dolnia Hani Narrative Discourse, Karen L. Gainer

Theses and Dissertations

Hani is a language in the Loloish family, spoken primarily in Yunnan Province of southwest China. This thesis presents a description of constituent order and participant reference in written Hani narrative discourse. The primary data source for this thesis consists of three narratives, which are included in the appendices.

Constituent order in Hani is largely constrained by the principle of natural information flow. In order to conform to this principle, some constituents may appear in two or more different positions in the clause, depending on the information structure of the assertion being made. Information structure also influences the use and …

Verbal Tone In Mpyemo, Bradley D. Festen

Theses and Dissertations

This thesis describes the tonal patterns and alternations present in the Mpyemo language (Bantu A.86c – ISO code mcx), with special attention to the verbal system. Rules and autosegmental representations are used to clarify and provide a formal analysis. A tone raising rule causes the underlying two-tone system to display three phonetic levels at the surface. This thesis explores nominalized verbs and verbs in the imperative. In addition, inflected verbs are described, although only a limited set of inflectional morphemes are treated. Thus, I look at verbs with inflectional prefixes for subject agreement, the perfect, and a single verbal auxiliary …

Movements, Resource Selection, And Risk Analyses For Parasitic Disease In An Expanding Moose Population In The Northern Great Plains, James J. Maskey Jr.

Theses and Dissertations

Little is known regarding moose ecology in North Dakota, and a decline in moose in northeastern North Dakota may be linked to parasites of white-tailed deer (Parelaphostrongylus tenuis and Fascioloides magna). I investigated the ecology of moose, including the potential effects of parasitic disease. I used global positioning system collars to estimate home ranges and habitat selection and collected fecal samples for diet estimates. I reviewed historical data and examined livers moose for evidence of F. magna infection. I examined 3730 white-tailed deer for P. tenuis and investigated whether prevalence had increased since 1991. I modeled the relationship …

Film Families: The Portrayal Of The Family In Teen Films From 1980 To 2007, Caroline Clayton Clark

Theses and Dissertations

American adolescents watch an average of 3.5 hours of television and movies everyday; many attend more than one movie a month. Adolescents as a group watch more movies than any other group of the population, yet little research has been done on what is shown in teen movies. Adolescence is a time when values, beliefs, and opinions are formed and the media has been found to be a place that adolescents find information that can influence the construction of these identities. While there has been a vast amount of research looking at the family as portrayed on television shows, there …

Tolerance And Accumulation Of Copper, Lead And Zinc By Ceratopteris Richardii, Dorothy Jelagat Cheruiyot

Theses and Dissertations

Environmental contamination has increased rapidly in recent years. There is a need to develop cheap and environmentally friendly remediation methods. Numerous studies have evaluated the ability plants to remove contaminants from the environment. The present study evaluated the ability of Ceratopteris richardii gametophytes and sporophytes to tolerate copper, lead and zinc and for the sporophytes to accumulate the three metals in their shoots. Spores were sown in plant medium treated with varying concentrations of Cu, Pb and Zn. Fifteen-day- old sporophytes were transferred into medium mixed with varying concentrations of the three metals. Ceratopteris richardii tolerated and accumulated each of …

Agenda-Setting And The Media: A Look At Child Welfare Legislation, 1995-2005, Tamara Temoney

Theses and Dissertations

This project used a content analysis methodology to determine the agenda-setting capacity of the media to influence child welfare legislation in a state legislature. With a foundation in agenda-setting theory, this study identifies how the coverage of child abuse and neglect in the print media impacts decision-makers to introduce legislation related to child abuse and neglect. Through a comparison of the issues covered in the newspaper with the issues receiving legislative attention, this study showed that media influence varies by topic, with some topics being more open to media affects than others. A second component of this study analyzed how …

Creation Of A Mouse With A Humanized Fpgs Gene Compatible With Normal Development, Linying Xie

Theses and Dissertations

Abstract: Folylpoly-γ-glutamate synthetase (FPGS) catalyzes the formation of polyglutamate forms of the reduced folates and antifolates such as methotrexate (MTX) and pemetrexed; this allows the retention of folates and antifolate cancer drugs inside the cell. The enzyme activity of FPGS is essential for cell proliferation and survival. The mouse fpgs gene contains two promoters spaced 10 kb apart which are activated in a tissue-specific manner. The upstream promoter (P1) and exons A1a and A1b are used in some differentiated tissues, mainly liver and kidney, whereas the downstream promoter (P2) and exon 1 are used in rapidly dividing cells. In contrast, …

An Investigation Of The Technological, Pedagogical And Content Knowledge Framework In Successful Chinese Language Classrooms, Su-Ling Hsueh

Theses and Dissertations

This qualitative case study investigates whether technological, pedagogical and content knowledge (TPCK) is balanced and integrated in Chinese language classrooms. Three expert Chinese teachers in technology-enhanced classrooms, as well as their students, were observed and studied. Four and a half months of data were collected in the form of classroom observations, interviews, reflective journals, and document analysis. Four basic findings were derived from the study. First, the TPCK framework reflected an observable instructional process for communication between teachers and students. However, teachers did not knowingly integrate technology, pedagogy and content in technology-enhanced classrooms. Second, content was the focal point during …

Design And Testing Of A Pumpless Microelectromechanical System Nanoinjector, Quentin Theodore Aten

Theses and Dissertations

A deeper understanding of human development and disease is made possible partly through the study of genetically modified model organisms, such as the common mouse (Mus musculus). By genetically modifying such model organisms, scientists can activate, deactivate, or highlight particular characteristics. A genetically modified animal is generated by adding exogenous (foreign) genetic material to one or more embryonic cells at their earliest stages of development. Frequently, this exogenous genetic material consists of specially engineered DNA, which is introduced into a fertilized egg cell (zygote). When successfully introduced into the zygote, the exogenous DNA will be incorporated into the …

The Open Road, Bryan Condra

Theses and Dissertations

In our journeys on the open road, we travel through a landscape of visual imagery composed of patterns, rhythms and a spectrum of changing colors. Our previous experiences, mental and physical attitudes and expectations, shape our perceptions. By visually interpreting and presenting my experiences of the journey on the open road I hoped to tell a story of how the open road energizes the creative spirit. My goal was to explore how the landscape is altered by motion and speed as we pass through it, and how the journey can be experienced in various ways. I wanted to investigate and …

In Vitro Models For Inhaled Corticosteroid (Ics) Aerosols: A Study Of Their Biopharmaceutics And Pharmacology, Deepika Arora

Theses and Dissertations

Lung cellular disposition and anti-inflammatory pharmacology of inhaled corticosteroids (ICSs) is complex, comprised of a cascade of aerosol deposition and dissolution, followed by cellular uptake for local pharmacological action. This project hypothesized that the kinetics of dissolution for certain ICS aerosols generated from inhaler products were kinetically rate-determined for their cellular uptake and local pharmacological action. A novel dissolution testing system was developed to determine the dissolution kinetics for the ICS aerosols. A total of 5 ICSs aerosols generated from 6 inhaler products were collected in 2.1-3.3 or 4.7-5.8 µm of aerodynamic diameters at 0.7-19.8 µg on filter membranes by …

The Effects Of Homography On Computer-Generated High Frequency Word Lists, Athelia Graham

Theses and Dissertations

This study investigated the significance of semantics in computer-generated word frequency counts in response to a call for new word lists (Read, 2000; Gardner, 2007). Read claims that no corpus projects to date have produced any "definitive, stand-alone word-frequency lists" (p. 226). Many researchers are wary of the fact that the concept of a word is never clearly defined in most studies that have dealt with word frequency counts. It is clear from the research that one universally acceptable construct for the concept of word does not exist. In fact, many past word frequency counts only examine word forms without …

The Expression And Function Of Phosphacan/Rptpβ In Adaptive Synaptogenesis After Traumatic Brain Injury, Janna Harris

Theses and Dissertations

Traumatic brain injury (TBI) affects 1.5 million Americans annually and is a major health concern. Increasing evidence suggests that the brain extracellular environment regulates plasticity and synaptic recovery following TBI. Here we have focused on phosphacan/RPTPβ, an alternatively spliced group of chondroitin sulfate proteoglycans which are prominent within the mature brain extracellular matrix (ECM). Previous studies show that phosphacan/RPTPβ influences neuronal migration, adhesion, neurite outgrowth, and morphogenesis. However, our understanding of how these important ECM components are involved in recovery from brain trauma remains unclear. In the present study, we used unilateral entorhinal cortex lesion (UEC), a model which induces …

An Analysis Of Document Retrieval And Clustering Using An Effective Semantic Distance Measure, Nathan Scott Davis

Theses and Dissertations

As large amounts of digital information become more and more accessible, the ability to effectively find relevant information is increasingly important. Search engines have historically performed well at finding relevant information by relying primarily on lexical and word based measures. Similarly, standard approaches to organizing and categorizing large amounts of textual information have previously relied on lexical and word based measures to perform grouping or classification tasks. Quite often, however, these processes take place without respect to semantics, or word meanings. This is perhaps due to the fact that the idea of meaningful similarity is naturally qualitative, and thus difficult …

This study was conducted to determinate carbon and nitrogen isotope fractionation in Bolivian and Chilean alpaca, llama and guanaco, hair, breath, plasma and feces. We also wanted to determine forage selection for these camelids using stable isotope technology. From the data, niche feeding and diet selection habits will determinate based on fecal composition. Bolivian sites were located near the high snow Altiplano Mountains at Tomarapi, Sajama, and at the Technical University Oruro's research center at Condoriri, Bolivia. Chilean samples were collected at INIA's (Instituto Nacional de Investigacion Agropecuaria) Kampenaike Research Station, Punta Arenas, Chile. Bolivian alpacas and llamas were 3 …

Specific Compartmentalization Of Iga Ascs In Mouse Salivary Glands Via Differential Expression Of Chemokines And Chemokine Receptors, Yuet Ching Law

Theses and Dissertations

The mucosal system, which forms a barrier between internal organ systems and the external environment, is frequently exposed to pathogenic microorganisms. Immunoglobulin A (IgA) antibody secreting cells (ASCs) localize in the lamina propria, and produce IgA antibodies which help protect mucosal tissues. The concept of a common mucosal immune system in which IgA ASCs have the ability to populate any mucosal site has been proposed (1, 2). However, recent research has suggested that IgA ASCs primed in different mucosal sites might possess different sets of chemokine receptors, and therefore migrate specifically to particular mucosal locations (3). In this study, the …

Ceramide Kinase And Ceramide-1-Phosphate, Dayanjan Wijesinghe

Theses and Dissertations

Ceramide-1-phosphate (C1P) is a bioactive lipid that has been implicated in many biological processes. Our laboratory has conclusively demonstrated its role in inflammation via activation of cPLA2α. The only known enzyme to date responsible for direct synthesis of C1P is ceramide kinase. Very little was known about this enzyme in terms of its enzyme kinetics and substrate specificity. As CERK is an enzyme that acts on membrane lipids, its kinetics cannot be studied using standard bulk dilutions methods. Thus we developed a surface dilution approach using Triton X 100 mixed micelles for studying the kinetics of CERK. We discovered that …

Blurring The Lines: The Intermingling Of Garden And Theater In Seventeenth Century France, Abbie Elizabeth Rufener

Theses and Dissertations

Seventeenth century French society was a time in which the arts flourished and were used to create an eminence of power and absolutism. The gardens of Vaux-le-Vicomte were commissioned by Nicolas Fouquet and designed by André Le Nôtre. The gardens created a political and social space through the characteristics of design and standards of order which together conveyed power and absolutism. Louis XIV, newly crowned king, recognized at Vaux the perfect vehicle for the portrayal of power. French theater at the same time was gaining popularity and establishing itself as a great art form. Similar to the gardens at Vaux …

The Design And Synthesis Of Zinc(Ii) Ion Fluorescence Sensors, Julius Ngunde Ngwendson

Theses and Dissertations

This work is a study of a new class of aromatic amines as fluorescent zinc sensors. N-(Carboxymethyl)-N-[3-[(carboxymethyl)amino]-2-methoxy-5-methylphenyl]glycinate exhibits more than 20-fold fluorescence enhancement in the presence of Zn(II) ions when excited at 300 nm. This compound shows a fluorescence emission at 390 nm, which in the presence of Zn(II) ion exhibits a 20 nm emission blue shift. The tetraacetate version, potassium N,N'-(2-methoxy-5-methyl-1,3-phenylene)bis[ N-(carboxymethyl)]glycinate, exhibits a 7-fold sensitivity to Zn(II) ion, and there is no emission band shift observed. Investigations point to the methoxy group for the ratiometric behavior and increased sensitivity to zinc. The diacetate versions—sodium N-(carboxymethyl)- N-(2-methoxyphenyl)glycinate, sodium N,N'-(2-methoxy-5-methyl-1,3-phenylene)bisglycinate …

Tumor Necrosis Factor Alpha Modulates Nmda Receptors In The Central Nervous System, Javier H. Jara

Theses and Dissertations

Multiple cytokines are secreted in the brain during inflammatory conditions and likely affect neuronal survival. Previous studies demonstrated that glutamate and tumor necrosis factor alpha (TNFα) kill neurons via activation of the NMDA and TNFα receptors, respectively. Nevertheless the mechanisms of neuronal death are not completely elucidated. The goal of this study was to characterize the signaling cross-talk pathway initiated during this inflammation-related mechanism of cell death. Stimulation of mouse cortical neuron cultures with TNFα resulted in a transient increase in NMDA receptor-dependent calcium influx that is additive with NMDA stimulation and inhibited by pretreatment with the NMDA receptor antagonist. …

Semantic Role Agency In Perceptions Of The Lexical Items Sick And Evil, Nathan G. Simmons

Theses and Dissertations

Inspired by an ongoing debate in the clinical sciences concerning the value of evil as a label for human behavior (Mowrer 1960, Staub 1999, Wellman 2000, Williams 2004 etc.), this thesis examines the semantic role of AGENT in the lexical items sick and evil. Williams makes the argument that the label evil removes responsibility from the doctor, whereas, the label sick empowers the doctor in bringing about a cure. While this view is not universally accepted in the field, it does bring to light an interesting question in applied linguistic semantics as to the assignment of agency with respect to …

The Church Of Jesus Christ Of Latter-Day Saints Enters Albania, 1992-1999, Nathan D. Pali

Theses and Dissertations

The Church of Jesus Christ of Latter-day Saints entered Albania in 1992. Albania was a unique and difficult place to establish the LDS Church. Under the communist dictatorship of Enver Hoxha religion was systematically eliminated from Albania and replaced with atheism. Additionally, missionaries were twice evacuated in the first decade in the country and the Book of Mormon was not available in Albanian until 1999. Despite these setbacks the LDS Church grew at a steady rate in Albania due to native Albanian interest and individual attention by missionaries.
