The Function of Oral Tradition in Mary Lou's Mass by Mary Lou Williams

The Function of Oral Tradition in Mary Lou's Mass by Mary Lou Williams

Date: August 1996
Creator: Fledderus, France
Description: The musical and spiritual life of Mary Lou Williams (1910 - 1981) came together in her later years in the writing of Mary Lou's Mass. Being both Roman Catholic and a jazz pianist and composer, it was inevitable that Williams would be the first jazz composer to write a setting of the mass. The degree of success resulting from the combination of jazz and the traditional forms of Western art music has always been controversial. Because of Williams's personal faith and aesthetics of music, however, she had little choice but to attempt the union of jazz and liturgical worship. After a biography of Williams, discussed in the context of her musical aesthetics, this thesis investigates the elements of conventional mass settings and oral tradition found in Mary Lou's Mass.

The Function of Social Structure in Controlling Violent Crime in Turkey

The Function of Social Structure in Controlling Violent Crime in Turkey

Access: Use of this item is restricted to the UNT Community.
Date: December 2010
Creator: Guclu, Idris
Description: This dissertation examines the relationship between social structural factors and violent crime rates in Turkey. The relationship between social structural characteristics and violent crime is worth exploring in areas that have attracted little academic attention, such as violent crime in Turkey. In order to understand and prevent the occurrence of crime, researchers have long investigated possible factors related to crime. Examining how crime varies across different regions can help us to understand underlying reasons for violent crime, which is considered one of the enduring problems in society. The findings of this research, to some extent, support the assumptions of social disorganization theory regarding the distribution of violent crime. Both the findings of multivariate and bivariate analysis indicated that poverty, unemployment, and family disruptions may have a positive effect on the distribution of violent crime in the cities of Turkey. The analysis of the effects of the social structure variables through the mediating variables, such as religious institutions, libraries and voluntary associations on the number of violent crimes and violent criminals, to some extent, support the tenets of social disorganization theory. However, all mediating variables cannot mediate all the indirect effects of social structural covariates. In brief, none of their indirect ...

Function of the ENOD8 gene in nodules of Medicago truncatula.

Function of the ENOD8 gene in nodules of Medicago truncatula.

Date: December 2006
Creator: Coque, Laurent
Description: To elaborate on the function(s) of the ENOD8 gene in the nodules of M. truncatula, several different experimental approaches were used. A census of the ENOD8 genes was first completed indicating that only ENOD8.1 (nt10554-12564 of GenBank AF463407) is highly expressed in nodule tissues. A maltose binding protein-ENOD8 fusion protein was made with an E. coli recombinant system. A variety of biochemical assays were undertaken with the MBP-ENOD8 recombinant protein expressed in E. coli, which did not yield the esterase activity observed for ENOD8 protein nodule fractions purified from M. sativa, tested on general esterase substrates, α-naphthyl acetate, and p-nitrophenylacetate. Attempts were also made to express ENOD8 in a Pichia pastoris system; no ENOD8 protein could be detected from Pichia pastoris strains which were transformed with the ENOD8 expression cassette. Additionally, it was shown that the ENOD8 protein can be recombinantly synthesized by Nicotiana benthamiana in a soluble form, which could be tested for activity toward esterase substrates, bearing resemblance to nodule compounds, such as the Nod factor. Transcription localization studies using an ENOD8 promoter gusA fusion indicated that ENOD8 is expressed in the bacteroid-invaded zone of the nodule. The ENOD8 protein was also detected in that same zone by ...

Functional analysis and elimination of SIB in an olive baboon (Papio hamadryas anubis).

Functional analysis and elimination of SIB in an olive baboon (Papio hamadryas anubis).

Access: Use of this item is restricted to the UNT Community.

Creator: Dorey, Nicole R.
Description: Self injurious behavior (SIB), such as self-biting and head-banging, has been reported to occur in approximately 10% of captive, individually housed primates (Novak, Kinsely, Jorgensen, and Hazen, 1998). Accounts of the causes of SIB range from environmental to physiological. However, to date, no researchers have investigated the possible influence of social consequences, delivered by handlers and keepers, in the maintenance of SIB. There is only one research report showing that self-injury can be shaped in primates by the manipulation of food as a reinforcing consequence for the animal's behavior. The current study investigated the effects of social contact as potentially reinforcing consequences for the SIB displayed by an olive baboon (Papio hamadryas anubis). Results indicated that the behavior was maintained by attention from humans. As treatment, reinforcement was arranged for an appropriate alternative attention-getting behavior, resulting in increases in the appropriate alternative behavior and decreases in SIB.

Functional and Categorical Analysis of Waveshapes Recorded on Microelectrode Arrays

Functional and Categorical Analysis of Waveshapes Recorded on Microelectrode Arrays

Date: May 2005
Creator: Schwartz, Jacob C.
Description: Dissociated neuronal cell cultures grown on substrate integrated microelectrode arrays (MEAs) generate spontaneous activity that can be recorded for up to several weeks. The signature wave shapes from extracellular recording of neuronal activity display a great variety of shapes with triphasic signals predominating. I characterized extracellular recordings from over 600 neuronal signals. I have preformed a categorical study by dividing wave shapes into two major classes: (type 1) signals in which the large positive peak follows the negative spike, and (type 2) signals in which the large positive peak precedes the negative spike. The former are hypothesized to be active signal propagation that can occur in the axon and possibly in soma or dendrites. The latter are hypothesized to be passive which is generally secluded to soma or dendrites. In order to verify these hypotheses, I pharmacologically targeted ion channels with tetrodotoxin (TTX), tetraethylammonium (TEA), 4-aminopyridine (4-AP), and monensin.

Creator: Bagchi, Rammyani
Description: Symbiotic nitrogen fixation occurs in plants harboring nitrogen-fixing bacteria within the plant tissue. The most widely studied association is between the legumes and rhizobia. In this relationship the plant (legumes) provides the bacteria (rhizobia) with reduced carbon derived from photosynthesis in exchange for reduced atmospheric nitrogen. This allows the plant to survive in soil, which is low in available of nitrogen. Rhizobia infect and enter plant root and reside in organs known as nodules. In the nodules the bacteria fix atmospheric nitrogen. The association between the legume, Medicago truncatula and the bacteria Sinorhizobium meliloti, has been studied in detail. Medicago mutants that have defects in nodulation help us understand the process of nitrogen fixation better. One such mutant is the Mtnip-1. Mtnip-1 plants respond to S. meliloti by producing abnormal nodules in which numerous aberrant infection threads are produced, with very rare rhizobial release into host plant cells. The mutant plant Mtnip-1 has an abnormal defense-like response in root nodules as well as defects in lateral root development. Three alleles of the Mtnip/latd mutants, Mtnip-1, Mtlatd and Mtnip-3 show different degrees of severity in their phenotype. Phylogenetic analysis showed that MtNIP/LATD encodes a protein belonging to the NRT1(PTR) family of ...

Functional Characterization of Plant Fatty Acid Amide Hydrolases

Functional Characterization of Plant Fatty Acid Amide Hydrolases

Date: December 2010
Creator: Kim, Sang-Chul
Description: Fatty acid amide hydrolase (FAAH) terminates the endocannabinoid signaling pathway that regulates numerous neurobehavioral processes in animals by hydrolyzing a class of lipid mediators, N-acylethanolamines (NAEs). Recent identification of an Arabidopsis FAAH homologue (AtFAAH) and several studies, especially those using AtFAAH overexpressing and knock-out lines suggest that a FAAH-mediated pathway exists in plants for the metabolism of endogenous NAEs. Here, I provide evidence to support this concept by identifying candidate FAAH cDNA sequences in diverse plant species. NAE amidohydrolase assays confirmed that several of the proteins encoded by these cDNAs indeed catalyzed the hydrolysis of NAEs in vitro. Kinetic parameters, inhibition properties, and substrate specificities of the plant FAAH enzymes were very similar to those of mammalian FAAH. Five amino acid residues determined to be important for catalysis by rat FAAH were absolutely conserved within the plant FAAH sequences. Site-directed mutation of each of the five putative catalytic residues in AtFAAH abolished its hydrolytic activity when expressed in Escherichia coli. Contrary to overexpression of native AtFAAH in Arabidopsis that results in enhanced seedling growth, and in seedlings that were insensitive to exogenous NAE, overexpression of the inactive AtFAAH mutants showed no growth enhancement and no NAE tolerance. However, both active ...

Functional Neural Toxicity and Endocrine Responses in Mice Following Naphthalene Exposure

Functional Neural Toxicity and Endocrine Responses in Mice Following Naphthalene Exposure

Date: August 2010
Creator: Colbert, Crystal
Description: Polycyclic aromatic hydrocarbons (PAHs) are a well studied and diverse class of environmental toxicants. PAHs act via the aryl hydrocarbon receptor (AhR), and studies have suggested that PAHs may elicit neurological and estrogenic effects. Doses of PAHs between 50 to 150 ppm may elicit neurotoxicity in rodent models. The present study investigated the effects of naphthalene on in vivo steroidogenesis in Swiss Webster male mice, and in vitro neural function of Balb-C/ICR mice frontal cortex neurons. These data suggest that naphthalene may not elicit steroidogenic effects at concentrations ranging from 0.2 to 25 mg/kg/day, following a 7 day subcutaneous dosing regime. In addition, naphthalene may cause functional toxicity of frontal cortex neurons at concentrations of 32 to 160 ppm naphthalene.

Functional Ontology Construction: A Pragmatic Approach to Addressing Problems Concerning the Individual and the Informing Environment

Functional Ontology Construction: A Pragmatic Approach to Addressing Problems Concerning the Individual and the Informing Environment

Date: May 2006
Creator: Anderson, Richard L.
Description: Functional ontology construction (FOC) is an approach for modeling the relationships between a user and the informing environment by means of analysis of the user's behavior and the elements of the environment that have behavioral function. The FOC approach is an application of behavior analytic techniques and concepts to problems within information science. The FOC approach is both an alternative and a compliment to the cognitive viewpoint commonly found in models of behavior in information science. The basis for the synthesis of behavior analysis and information science is a shared tradition of pragmatism between the fields. The application of behavior analytic concepts brings with it the notion of selection by consequence. Selection is examined on the biological, behavioral, and cultural levels. Two perspicuous examples of the application of the FOC modeling approach are included. The first example looks at the document functioning as a reinforcer in a human operant experimental setting. The second example is an examination of the verbal behavior of expert film analyst, Raymond Bellour, the structure of a film he analyzed, and the elements of the film's structure that had behavioral function for Bellour. The FOC approach is examined within the ontological space of information science.

Functional Properties and Organization of Primary Somatosensory Cortex

Functional Properties and Organization of Primary Somatosensory Cortex

Date: December 1993
Creator: Esteky, Hossein
Description: The physiological characteristics and organization of cat primary somatosensory cortex (SI) were studied in electrophysiological and anatomical experiments. In single cell recording experiments, quantitatively controlled mechanical stimuli were used to examine the responses of SI cortical neurons to the velocity component of skin or hair displacement. The firing frequency of most rapidly adapting neurons increased as stimulus velocity was increased. Rapidly adapting neurons were classified based on their response patterns to constant-velocity ramp stimuli. Neurons in these classes differed significantly in sensitivity to stimulus velocity and amplitude, adaptation rate, and spontaneous firing rate. The results suggest that frequency coding of stimulus displacement velocity could be performed by individual SI rapidly adapting neurons, and that the classes of rapidly adapting neurons may play different roles in sensation of tactile stimuli. Tract-tracing experiments were used to investigate the ipsilateral corticocortical connections of areas 3b and 2 in SI. Different patterns of connections were found for these areas: area 2 projects to areas 3b, 1, 3a, 5a, 4 and second somatosensory cortex (SII), and area 3b projects to areas 2, 1, 3a and SII. To further compare the organization of these areas, the thalamic input to the forepaw representation within each area was ...

Functionalization and characterization of porous low-κ dielectrics.

Access: Use of this item is restricted to the UNT Community.
Date: May 2005
Creator: Orozco-Teran, Rosa Amelia
Description: The incorporation of fluorine into SiO2 has been shown to reduce the dielectric constant of the existing materials by reducing the electrical polarizability. However, the incorporation of fluorine has also been shown to decrease film stability. Therefore, new efforts have been made to find different ways to further decrease the relative dielectric constant value of the existing low-k materials. One way to reduce the dielectric constant is by decreasing its density. This reduces the amount of polarizable materials. A good approach is increasing porosity of the film. Recently, fluorinated silica xerogel films have been identified as potential candidates for applications such as interlayer dielectric materials in CMOS technology. In addition to their low dielectric constants, these films present properties such as low refractive indices, low thermal conductivities, and high surface areas. Another approach to lower k is incorporating lighter atoms such as hydrogen or carbon. Silsesquioxane based materials are among them. However, additional integration issues such as damage to these materials caused by plasma etch, plasma ash, and wet etch processes are yet to be overcome. This dissertation reports the effects of triethoxyfluorosilane-based (TEFS) xerogel films when reacted with silylation agents. TEFS films were employed because they form robust silica ...

Functions of Quotations in Steven Stucky's Oratorio August 4, 1964 and Their Placements within the Context of a Quotation Continuum: Cultural, Commentary, Remembrance, and Unity

Date: May 2011
Creator: Davenport, Jennifer Tish
Description: The oratorio August 4, 1964 is a twelve-movement work for orchestra, chorus, and four soloists written by Steven Stucky. The premise for the libretto, adapted by Gene Scheer, is the confluence of two events during one day (August 4, 1964) in the life of Lyndon B. Johnson. Although the main idea of the libretto focuses on these two events of this one day, many cultural references of the 1960's in general can be found as well, such as quotations from the well-known song "We Shall Overcome." Stucky borrows from a motet he wrote in 2005 for another quotation source utilized in this oratorio, "O Vos Omnes." My goal in this thesis is to reveal and analyze the many different levels of quotations that exist within August 4, 1964, to explore each quotation's individual function within the oratorio (as a cultural gesture, commentary or remembrance), and to examine the structural coherence that emerges as a result of their use within the oratorio.

Functions of self-injurious thoughts and behaviors within adolescent inpatients.

Functions of self-injurious thoughts and behaviors within adolescent inpatients.

Date: December 2008
Creator: Thomas, Peter F.
Description: The primary interest of this investigation concerned the self-injurious thoughts and behaviors (SITBs) of inpatient adolescents. Previous researchers have provided descriptive information regarding either automatic (or intrinsic) and social components using the Self-Injurious Thoughts and Behaviors Interview (SITBI). However, the presence and trends of these components have not firmly been established, suggesting the need to explore this area further. Eighty-two adolescent inpatients were selected and interviewed using the SITBI to evaluate the predictive ability of self-reported self-injurious behavior with regard to social and automatic, negative and positive functions. Results showed that depending on the type of thought or behavior displayed one could discern the motivation behind their actions. Automatic-Negative was seen to have the strongest relationship across all SITB behaviors while Automatic-Negative was not found to be relatively low compared to other SITB behaviors. Both Social-Positive and Social-Negative were found to be present in moderate relationships compared to Automatic in general.
