A Study Of The Attitudes Of Junior-High And Middle-Level Principals Toward Parent Involvement In Arkansas, Marian G. Lacey

Theses and Dissertations

The study is a replication of a study by Brittle (1994) that researched attitudes of elementary principals toward parent involvement in the Commonwealth of Virginia. The 1997 Arkansas study identified and analyzed the attitudes of middle-level and junior-high principals toward parental involvement. The population for the study consisted of all middle-level and junior-high principals in the state of Arkansas. Data were analyzed using descriptive and correlational statistics to answer the research questions. The study revealed how strongly Arkansas middle-level or junior-high principals believe in parent involvement. Information concerning the principals' perceived role in implementing and fostering parent involvement in their …

Characteristics Of Students Who Seek Admission And Registration After The Beginning Of The Academic Term, Janet Vaughan Danley

Theses and Dissertations

Colleges and universities which permit students to apply for admission and/or register for classes after the beginning of the academic term may be adhering to an institutional policy which encourages unrestricted access to all qualified applicants. However, by permitting such students late entry, the late enrolling students, the students who were admitted and registered in a timely manner, the faculty, and the institution may suffer as a result. This study explored one institution's experience with late enrolling students. The students themselves were the primary focus of the study. Faculty and academic advisors who came into contact with the late enrolling …

Determination Of Rates And Patterns Of Recombination At The Maize Red Color (R1) Locus, William R. Dietrich

Theses and Dissertations

Homologous recombination has been studied in many plant and animal systems. In maize, most recombination occurs intragenically. The current study assessed the frequency and location of meiotic recombination at the maize red color (r1) gene. Three independent mutant (colorless seed) alleles derived from the colored seed allele, R-sc:124, were made heterozygous with the colored plant allele, r-r:n142. Each mutant resulted from the insertion of a Dissociation (Ds) transposable element into the 3' end of R-sc:124. In the presence of Activator (Ac), each Ds insertion allele (r-sc:mutables) produced spotted seeds and germinal reversion to fully colored seeds due to the vi …

Immunocytochemical Study Of Apoptosis Signaling In Nb2 Lymphoma Cells, Angelo P. Guanzon

Theses and Dissertations

In the absence of mitogen, administration of Dexamethasone (Dex) induces apoptosis, or programmed-cell death in the Nb2 lymphoma cell. Addition of prolactin (Prl), on the other hand, blocks this effect. As a model for apoptosis, we were able to investigate this Dex-Prl interaction by means of a morphological approach: one that could be visualized under a light microscope. This approach allowed us to achieve several aims. First, we were able to develop a method of cell quantification befitting a morphological study based upon the hemacytometer. Second, with Trypan Blue exclusion, we were able to verify Dex/Prl-responsiveness in the Nb2 cells. …

Determinants Of Participation In The Ad Hoc Computer-Supported Workgroup, Nancy A. Floyd

Theses and Dissertations

The increase of end-user computing, including the use of computer-mediated communication systems (CMCS), is one of the most significant changes to occur in business information systems in recent years. Researchers suggest that changes in technology lead to changes in the way individuals think about work and how they perform it. An important question is how the use of CMCS is changing work and work relationships. This study considers a portion of this question; it asks "What makes individuals willing to participate in a computer-supported workgroup (CSWG)."

This study considered the relationship between three variables (sex, anonymity, and token status) and …

Changes In Gabaa̳ Receptor Expression And Alterations In Ca⁺⁺/Calmodulin-Dependent Protein Kinase Ii Activity In A Hippocampal Neuronal Culture Model Of Epilepsy, Robert Eagan Blair

Theses and Dissertations

Expression levels of GABAA receptor subunits and activity of the Ca++ /calmodulin-dependent protein kinase II (CaM kinase II) enzyme system were evaluated in an in vitro hippocampal neuronal culture model of epilepsy. Treatment of hippocampal neuronal cultures with Mg++-free media for 3 hours results in the induction of an enduring "epileptic" state as evidenced by the expression of spontaneous recurrent seizure (SRS) discharge. The induction of the SRS activity was shown to be a N-methyl-D-aspartate (NMDA) receptor, Ca++-dependent mechanism (Sombati and DeLorenzo, J Neurophys., 73 (4), 1995). Significant and long-lasting decreases in mRNA expression for the GABAA α2 and α5 …

Aegis Data Analysis And Reduction (Adar) In Support Of The Aegis Weapon System (Aws), June Bullard Gaines

Theses and Dissertations

The AEGIS Weapons System (AWS), part of the AEGIS Combat System (ACS), is an integral part of the defense system on U.S. Navy AEGIS-class ships. AEGIS Data Analysis and Reduction (ADAR) has been developed to assist in the evaluation of the AWS data. ADAR, along with the AWS and ACS, has evolved through the years to accommodate advances in technology and computer programming languages. Additionally, ADAR has evolved so that users located at sites other than the Naval Surface Warfare System Dahlgren Division (NSWCDD), Dahlgren, Virginia, can reduce tactical system data and perform data analysis using the reduced data.

The Relation Between The Nutritional Status And The Acute Respiratory Infections In Children Younger Than Five Years Of Age In The Indigenous, Black, And Mestizo Ethnic Groups Of The Rural Area In The Imbabura Province, 1998-1999, Sandra Chiles

Theses and Dissertations

The problems of social-economics, culture, politics, and health, among those, are factors that influence both directly and indirectly the style of life of hundreds of thousands of people, due to the lack of economic resources, unemployment, poverty, their own culture can lead to a more serious state of health, consequently causing problems of their nutritional state, such as obesity in its varying degrees of malnutrition, in addition to the presence of preventable illnesses such as acute respiratory disease (IRA), that seriously affect the infant population. Factors, consequences, everything becomes one vicious circle that can be broken thereby preventing more deaths …

Adenosine 3', 5'-Cyclic Monophosphate Activation Of Islet Chloride Channels, Anjali Varandani

Theses and Dissertations

The objective of this thesis was to understand the regulation of islet Cl⁻ current by cAMP. This current, known as I_cl,islet flew is the first Cl⁻ channel current characterized in pancreatic �� cells. I_cl,islet has been hypothesized to modulate insulin secretion through changes in islet electrical activity. Both 5 ��M forskolin and 100 ��M IBMX (3-isobutyl-1-methylxanthine), agents that increase intracellular cAMP, were shown to activate an outwardly-rectifying ionic current in HIT cells that closely resembled I_cl,islet. The current was blocked when iodide was substituted for external Cl⁻ or when the Cl⁻ channel blocker niflumic acid was …

Determining Capture Zones For Three-Dimensional, Heterogeneous, Anisotropic Aquifers By Monte Carlo Analysis, Jon Paul Jones

Theses and Dissertations

Most methods of delineating capture zones for pump-and-treat remedial design and wellhead protection assume a two-dimensional, homogeneous aquifer. Aquifers, however, are three-dimensional and heterogeneous, thereby introducing uncertainty in capture zone analysis. This study used a Monte Carlo analysis of three sets of statistical parameters defining aquifer heterogeneity. Each set had a different variance for the mean natural log hydraulic conductivity, which varied among the sets by a factor of four. The ensemble means of the capture zones for each set were estimated from 10 randomly generated fields with 12 layers each which were superimposed on each other for a total …

Epideictic Rhetoric And The Formation Of Collective Identity: Nineteenth-Century Mormon Women In Praise Of Polygamy, Robbyn Thompson Scribner

Theses and Dissertations

In this thesis, I will proceed as follows: my first chapter will be a general overview of epideictic rhetoric, focusing on the limitations of how it has traditionally been viewed and understood by theorists. At the end of that chapter I will establish a working definition of epideictic which extends traditional views about how epideictic can function in certain types of writings, focusing on the important role of the speaker in epideictic rhetoric and how it can work in enabling a community to create a collective identity. In the remainder of the thesis, I will analyze two texts in which …
