An Actor-Partner Interdependence Model of Attachment Processes, Conflict Resolution, and Psychological Abuse on Relationship Quality in a Community Sample of Heterosexual Couples.
The purpose of this study is to determine whether adult attachment style, psychological abuse in the marriage, conflict resolution strategies, and gender are associated with relational quality in childless couples in the early years of their marriage. Data were collected from 92 married couples who were recruited from university campuses, churches, and community organizations through e-mails, flyers, newspaper advertisements and mailings. Conceptualizing the interdependence of dyadic data from the actor-partner interdependence model (APIM), multilevel linear modeling (MLM) was used to analyze differences within and between couples. It was hypothesized that higher levels of attachment anxiety or avoidance, psychological abuse, and maladaptive conflict resolution strategies would be associated with lower relational quality. Results indicated that attachment avoidance had stronger associations with relational quality than did attachment anxiety, and that higher levels of attachment avoidance were associated with lower relational quality. Additionally, findings indicated a direct negative relationship between both actor and partner psychological abuse and the actor's relational quality. The discussion section addresses strengths and limitations of the present study as well as directions for future research. digital.library.unt.edu/ark:/67531/metadc9932/

The Acute Dying Experience
Article discussing the acute dying experience (ADE), which incorporates peritraumatic dissociation and hyperarousal into an experiential continuum lasting seconds to minutes. It is instantly triggered by the sudden, clear perception of threat of significant injury and/or death and followed, at times, by physical trauma, physiological derangement, and loss of consciousness. Results from this and other studies show that paradoxically the more terrifying and traumatic an accident may appear, the more peaceful and painless it may actually be experienced. digital.library.unt.edu/ark:/67531/metadc799345/

Acute Effects of the Antibiotic Streptomycin on Neural Network Activity and Pharmacological Responses
Access: Use of this item is restricted to the UNT Community.
The purpose of this study is to find out that if antibiotic streptomycin decreases neuronal network activity or affects the pharmacological responses. The experiments in this study were conducted via MEA (multi-electrode array) technology which records neuronal activity from devices that have multiple small electrodes, serve as neural interfaces connecting neurons to electronic circuitry. The result of this study shows that streptomycin lowered the spike production of neuronal network, and also, sensitization was seen when neuronal network pre-exposed to streptomycin. digital.library.unt.edu/ark:/67531/metadc700026/
The Acute Hormonal Response to the Kettlebell Swing Exercise
The purpose of this investigation was to examine the acute hormonal response to a bout of kettlebell swing exercise. Ten healthy men (19-30 y, 23.6 ± 3.5 y, 174.6 ± 5.7 cm, 78.7 ± 9.9 kg) who were engaged in resistance training at least twice per week but were inexperienced with kettlebell swings participated in this study. Participants were familiarized with the kettlebell swing exercise during an initial visit. During the subsequent experimental protocol visit, participants performed 12 rounds of 30 seconds of 16-kg kettlebell swings alternated with 30 seconds of rest. Heart rate (HR) and rating of perceived exertion (RPE) were measured at the end of every round of swings. Fasted blood samples were collected pre-exercise (PRE), immediately post (IP), 15 minutes post (P15), and 30 minutes post exercise (P30) and analyzed for total testosterone (T), growth hormone (GH), cortisol, and lactate concentrations. Participants completed a total of 227 ± 23 swings (average swings per round: 19 ± 2). HR and RPE increased significantly (P < 0.05) throughout the exercise protocol. Lactate concentrations were significantly increased at all post exercise time points compared to PRE. T was significantly increased at IP compared to PRE. GH was significantly increased at IP, P15, and P30 compared to PRE. Cortisol was significantly increased at IP and P15 compared to PRE. 12 rounds of 30 seconds of kettlebell swing exercise induced an acute increase in T, GH, and cortisol concentrations in resistance trained men. Additionally, this exercise protocol induced a large increase in HR and lactate concentration. Thus, the kettlebell swing exercise might provide an effective method for simultaneous endurance and resistance training. digital.library.unt.edu/ark:/67531/metadc407736/
N-Acylethanolamine Metabolism During Seed Germination: Molecular Identification of a Functional N-Acylethanolamine Amidohydrolase
N-Acylethanolamines (NAEs) are endogenous lipid metabolites that occur in a variety of dry seeds, and their levels decline rapidly during the first few hours of imbibition (Chapman et al., 1999, Plant Physiol., 120:1157-1164). Biochemical studies supported the existence of an NAE amidohydrolase activity in seeds and seedlings, and efforts were directed toward identification of DNA sequences encoding this enzyme. Mammalian tissues metabolize NAEs via an amidase enzyme designated fatty acid amide hydrolase (FAAH). Based on the characteristic amidase signature sequence in mammalian FAAH, a candidate Arabidopsis cDNA was identified and isolated by reverse transcriptase-PCR. The Arabidopsis cDNA was expressed in E. coli and the recombinant protein indeed hydrolyzed a range of NAEs to free fatty acids and ethanolamine. Kinetic parameters for the recombinant protein were consistent with those properties of the rat FAAH, supporting identification of this Arabidopsis cDNA as a FAAH homologue. Two T-DNA insertional mutant lines with disruptions in the Arabidopsis NAE amidohydrolase gene (At5g64440) were identified. The homozygous mutant seedlings were more sensitive than the wild type to exogenously applied NAE 12:0. Transgenic seedlings overexpressing the NAE amidohydrolase enzyme showed noticeably greater tolerance to NAE 12:0 than wild type seedlings. These results together provide evidence in vitro and in vivo for the molecular identification of Arabidopsis NAE amidohydrolase. Moreover, the plants with altered NAE amidohydrolase expression may provide new tools for improved understanding of the role of NAEs in germination and seedling growth. digital.library.unt.edu/ark:/67531/metadc4575/
N-Acylethanolamine (NAE) Profiles Change During Arabidopsis Thaliana Seed Germination and Seedling Growth
An understanding of the potential roles as lipid mediators of a family of bioactive metabolites called N-acylethanolamines (NAEs) depends on their accurate identification and quantification. The levels of 18C unsaturated NAEs (e.g. NAE18:2, NAE 18:3, etc.) in wild-type seeds (about 2000 ng/g fw) generally decreased by about 80% during germination and post-germinative growth. In addition, results suggest NAE-degradative fatty acid amide hydrolase (FAAH) expression does not play a major role in normal NAE metabolism as previously thought. Seedlings germinated and grown in the presence of abscisic acid (ABA), an endogenous plant hormone, exhibited growth arrest and secondary dormancy, similar to the treatment of seedlings with exogenous N­lauroylethanolamine (NAE12:0). ABA-mediated growth arrest was associated with higher levels of unsaturated NAEs. Overall, these results are consistent with the concept that NAE metabolism is activated during seed germination and suggest that the reduction in unsaturated NAE levels is under strict temporal control and may be a requirement for normal seed germination and post-germinative growth. digital.library.unt.edu/ark:/67531/metadc5333/
N-Acylethanolamines and Plant Phospholipase D
Recently, three distinct isoforms of phospholipase D (PLD) were identified in Arabidopsis thaliana. PLD α represents the well-known form found in plants, while PLD β and γ have been only recently discovered (Pappan et al., 1997b; Qin et al., 1997). These isoforms differ in substrate selectivity and cofactors required for activity. Here, I report that PLD β and γ isoforms were active toward N-acylphosphatidylethanolamine (NAPE), but PLD α was not. The ability of PLD β and γ to hydrolyze NAPE marks a key difference from PLD α. N-acylethanolamines (NAE), the hydrolytic products of NAPE by PLD β and γ, inhibited PLD α from castor bean and cabbage. Inhibition of PLD α by NAE was dose-dependent and inversely proportional to acyl chain length and degree of unsaturation. Enzyme kinetic analysis suggested non-competitive inhibition of PLD α by NAE 14:0. In addition, a 1.2-kb tobacco (Nicotiana tabacum L.) cDNA fragment was isolated that possessed a 74% amino acid identity to Arabidopsis PLD β indicating that this isoform is expressed in tobacco cells. Collectively, these results provide evidence for NAE producing PLD activities and suggest a possible regulatory role for NAE with respect to PLD α. digital.library.unt.edu/ark:/67531/metadc279270/
ADA Compliance and Accessibility of Aquatic Facilities in the North Texas Area
The purpose of this study was to determine the degree to which existing aquatic facilities in the North Texas metroplex complied with the 1991 Americans with Disabilities Act Accessibility Guidelines (ADAAG) and the proposed Americans with Disabilities Act Accessibility Guidelines: Recreation Facilities (ADAAG supplement). Fifty-two aquatic facilities were evaluated based on: parking lot, ticket counter, gate/entry, restroom, dressing area, drinking fountain, pathway, and pool entry method structural domains. Physical measurements and a few direct observations were recorded on the survey instrument. Surveys were then reviewed and facility scores were tabulated. No facility was found to be 100% compliant with ADAAG and the ADAAG supplement. Aquatic facilities are already struggling to catch up with the 1991 ADAAG, but when the United States Department of Justice approves the proposed ADAAG supplement, aquatic facilities will fall even further behind. digital.library.unt.edu/ark:/67531/metadc3557/
The Adagio of Mahler's Ninth Symphony: A Schenkerian Analysis and Examination of the Farewell Story
Mahler's Ninth Symphony, since its premier in 1912, has sparked much debate about its programmatic meaning. This thesis provides an in-depth analysis of the Adagio and an examination of the controversy of the farewell story. In the process of the analysis I have compared my findings to some of the important authors in Mahler's field such as Vera Micznik, Henry-Louis de La Grange, and Christopher Orlo Lewis. Some of the conclusions are that a closer investigation of the music is necessary and that the programmatic reading of the farewell story can be appropriate. digital.library.unt.edu/ark:/67531/metadc68028/
Adam Smith Revisited
This study represents an interpretation of Adam Smith's attitude toward a commercial society based upon natural liberty. In developing the thesis that the two works, The Theory of Moral Sentiments and Wealth of Nations, are logically consistent, it is necessary to establish the reason of reasons why Adam Smith embraced a commercial society based upon the "obvious and simple system of natural liberty." It will be established that he embraced such as system because it allowed the maximum accumulation of capital, which is the manifestation of being truly virtuous as developed in his Moral Sentiments. To go one step further, it will be seen that, so far as Smith is concerned, it is the rising bourgeoisie, the manufacturers and artificers, which is truly virtuous, i.e., accumulates capital. digital.library.unt.edu/ark:/67531/metadc130789/

Adapting Filial Therapy for Families who have a Child with a Life-Threatening Illness
Utilizing a collective case study design, I examined and described the filial therapy (FT) process and adaptations discovered to be necessary and unnecessary in working with families who have a child with a life-threatening illness in the hospital setting. Data from a total of 7 parents was utilized, including those who terminated early, in order to gain a greater understanding of adapting FT for families who have a child with a life-threatening illness and their participation patterns. The parents attended 10 one- to two-hour FT sessions. The data was analyzed to examine for themes, patterns and relationships intrinsically with each case participant, as well as across cases. Analysis indicated that parents with a child with a life-threatening illness had great difficulty committing to attend FT; and a high rate of attrition occurred for those who did commit. A theme regarding flexibility was found to be of eminent importance in a variety of manifestations including therapeutic methods, session format, location and time of sessions, and intense vs traditional FT. Therapeutic adaptations in flexibility found to be important including openness to cathartic and personal parenting sessions, tolerance of forgetfulness, and lowering typical therapeutic concerns of dependency in the relationship. An inability for parents in this situation to benefit from intense FT methods was also noted. Changes noted in the child of focus included increased confidence, increased cooperation in the medical setting, increased communication with the parent and with medical staff regarding medical issues, and increased communication with the parent regarding personal feelings and issues. Changes noted in the parents included increased confidence in parenting skills, increased awareness of the child's perceptions of the environment, increased tolerance in allowing the child to struggle in and out of the medical setting, with both emotional and physical pain in order to gain coping skills, increased ability to allow the child to empower self, and increased abilities in limit setting. digital.library.unt.edu/ark:/67531/metadc4572/
Adapting on the Plains: the United States Army's Evolution of Mobile Warfare in Texas, 1848-1859
The Army, despite having been vexed for a century on how to effectively fight the Plains Indians, ultimately defeated them only a decade after the Civil War. This thesis will bring to the forefront those individuals who adapted fighting techniques and ultimately achieved victories on the Texas frontier before the Civil War. The majority of these victories came as a result of mounted warfare under the direction of lower ranking officers in control of smaller forces. The tactic of fighting Indians from horseback was shown to be effective by the Rangers and later emulated by the Army. digital.library.unt.edu/ark:/67531/metadc271787/
Adapting to Climate Change in Europe and Central Asia
Contrary to popular perception, ECA faces significant threats from climate change, with a number of the most serious risks already in evidence. Vulnerability over the next ten to twenty years will be dominated by socio‐economic factors and legacy issues. Even countries and sectors that stand to benefit from climate change are poorly positioned to do so. The next decade offers a window of opportunity for ECA countries to make their development more resilient to climate change while reaping numerous co‐benefits. digital.library.unt.edu/ark:/67531/metadc501470/
Adapting Water Management A Primer on Coping with Climate Change
This primer is intended as a guide to some of the basic issues surrounding water management from a climate change perspective. It includes information on climate change impacts on various freshwater ecosystems as well as precipitation. Also addressed is how the assessment of vulnerability should distinguish between impacts assessment, which attempts to project future biophysical and ecological changes in a deterministic manner, and vulnerability assessment, which attempts to combine an assessment of future suites of change with an assessment of the resilience of ecosystems and management institutions. digital.library.unt.edu/ark:/67531/metadc226773/
Adaptive Advantages of Carotenoid Pigments in Alpine and Subalpine Copepod Responses to Polycyclic Aromatic Hydrocarbon Induced Phototoxicity
Alpine zooplankton are exposed to a variety of stressors in their natural environment including ultraviolet radiation. Physiological coping mechanisms such as the accumulation of photoprotective compounds provide these zooplankton protection from many of these stressors. Elevated levels of carotenoid compounds such as astaxanthin have been shown to help zooplankton survive longer when exposed to ultraviolet radiation presumably due to the strong antioxidant properties of carotenoid compounds. This antioxidant capacity is important because it may ameliorate natural and anthropogenic stressor-induced oxidative stress. While previous researchers have shown carotenoid compounds impart increased resistance to ultraviolet radiation in populations of zooplankton, little work has focused on the toxicological implications of PAH induced phototoxicity on zooplankton containing high levels of carotenoid compounds. This thesis discusses research studying the role that carotenoid compounds play in reducing PAH induced phototoxicity. By sampling different lakes at elevations ranging from 9,500' to 12,700' in the front range of the Colorado Rocky Mountains, copepod populations containing different levels of carotenoid compounds were obtained. These populations were then challenged with fluoranthene and ultraviolet radiation. Results discussed include differences in survival and levels of lipid peroxidation among populations exhibiting different levels of carotenoid compounds, and the toxicological and ecological implications of these results. digital.library.unt.edu/ark:/67531/metadc28444/
An Adaptive Linearization Method for a Constraint Satisfaction Problem in Semiconductor Device Design Optimization
The device optimization is a very important element in semiconductor technology advancement. Its objective is to find a design point for a semiconductor device so that the optimized design goal meets all specified constraints. As in other engineering fields, a nonlinear optimizer is often used for design optimization. One major drawback of using a nonlinear optimizer is that it can only partially explore the design space and return a local optimal solution. This dissertation provides an adaptive optimization design methodology to allow the designer to explore the design space and obtain a globally optimal solution. One key element of our method is to quickly compute the set of all feasible solutions, also called the acceptability region. We described a polytope-based representation for the acceptability region and an adaptive linearization technique for device performance model approximation. These efficiency enhancements have enabled significant speed-up in estimating acceptability regions and allow acceptability regions to be estimated for a larger class of device design tasks. Our linearization technique also provides an efficient mechanism to guarantee the global accuracy of the computed acceptability region. To visualize the acceptability region, we study the orthogonal projection of high-dimensional convex polytopes and propose an output sensitive algorithm for projecting polytopes into two dimensions. digital.library.unt.edu/ark:/67531/metadc500248/
Adaptive Planning and Prediction in Agent-Supported Distributed Collaboration.
Agents that act as user assistants will become invaluable as the number of information sources continue to proliferate. Such agents can support the work of users by learning to automate time-consuming tasks and filter information to manageable levels. Although considerable advances have been made in this area, it remains a fertile area for further development. One application of agents under careful scrutiny is the automated negotiation of conflicts between different user's needs and desires. Many techniques require explicit user models in order to function. This dissertation explores a technique for dynamically constructing user models and the impact of using them to anticipate the need for negotiation. Negotiation is reduced by including an advising aspect to the agent that can use this anticipation of conflict to adjust user behavior. digital.library.unt.edu/ark:/67531/metadc4702/
Adaptive Power Management for Autonomic Resource Configuration in Large-scale Computer Systems
In order to run and manage resource-intensive high-performance applications, large-scale computing and storage platforms have been evolving rapidly in various domains in both academia and industry. The energy expenditure consumed to operate and maintain these cloud computing infrastructures is a major factor to influence the overall profit and efficiency for most cloud service providers. Moreover, considering the mitigation of environmental damage from excessive carbon dioxide emission, the amount of power consumed by enterprise-scale data centers should be constrained for protection of the environment.Generally speaking, there exists a trade-off between power consumption and application performance in large-scale computing systems and how to balance these two factors has become an important topic for researchers and engineers in cloud and HPC communities. Therefore, minimizing the power usage while satisfying the Service Level Agreements have become one of the most desirable objectives in cloud computing research and implementation. Since the fundamental feature of the cloud computing platform is hosting workloads with a variety of characteristics in a consolidated and on-demand manner, it is demanding to explore the inherent relationship between power usage and machine configurations. Subsequently, with an understanding of these inherent relationships, researchers are able to develop effective power management policies to optimize productivity by balancing power usage and system performance. In this dissertation, we develop an autonomic power-aware system management framework for large-scale computer systems. We propose a series of techniques including coarse-grain power profiling, VM power modelling, power-aware resource auto-configuration and full-system power usage simulator. These techniques help us to understand the characteristics of power consumption of various system components. Based on these techniques, we are able to test various job scheduling strategies and develop resource management approaches to enhance the systems' power efficiency. digital.library.unt.edu/ark:/67531/metadc804939/
