The current study focuses on phase stability and evolution in the titanium-zinc titanium-copper and titanium-antimony systems. The study utilized the Laser Engineering Net Shaping (LENS™) processing technique to deposit compositionally graded samples of three binary system in order to allow the assessment of phase stability and evolution as a function of composition and temperature the material is subjected to. Through LENS™ processing it was possible to create graded samples from Ti-xSb (up to 13wt%) and Ti-xCu (up to 16wt%). The LENS™ deposited gradient were solutionized, and step quenched to specific aging temperature, and the resulting microstructures and phase were characterized utilizing XRD, EDS, SEM, FIB and TEM. The Ti-Zn system proved incapable of being LENS™ deposited due to the low vaporization temperature of Zn; however, a novel processing approach was developed to drip liquid Zn onto Ti powder at temperatures above β transus temperature of Ti (882 ◦C) and below the vaporization temperature of Zn (907 ◦C). The product of this processing technique was characterized in a similar way as the graded LENS™ depositions. From measurements performed on Ti-Sb it seems that Sb could be a potential α stabilizer in Ti due to the presence of a mostly homogeneous α …

Cardiovascular disease is the leading cause of death in the United States. Chronic short sleep duration is also a significant public health problem and has been linked to several markers and outcomes of cardiovascular disease. To date, inconsistency of assessments of sleep duration and insufficiency, use of covariates, and cardiovascular disease measurement across studies limits strong conclusions about the relationship between sleep duration, sleep insufficiency, and cardiovascular disease. The current study examined the association between sleep duration, sleep insufficiency, and a marker of preclinical coronary heart disease (i.e., carotid intima-media thickness) in a community sample using a cross-sectional design. Some evidence for a relationship between sleep duration and cIMT was found, with longer sleep duration predicting higher cIMT in some segments. Additionally, the interaction between sleep duration and sleep insufficiency was significant. However, neither of these effects were significant after adjusting for age and in some cases race/ethnicity, suggesting demographics may explain this association. Actigraphy and sleep diary duration assessments demonstrated significantly different correlations with cIMT in some segments, suggesting the nature of the assessment method may impact the strength or direction of the relationship between sleep duration and cIMT. Limitations and future directions are discussed.

Research has illustrated the interrelatedness of childhood physical fitness and psychological wellbeing, psychological wellbeing and academic achievement, as well as physical fitness and academic achievement. In this study, we proposed that psychological wellbeing (self-esteem and depression) serves as a mediator between physical fitness and academic achievement during adolescence. In a sample of middle school children (N = 1,530), significant correlations were found between all three variables (p.0001). A hierarchical regression analysis was performed to assess the associations between physical fitness, psychological wellbeing, and academic achievement. The regression analysis reported a significant partial mediation effect. The results of this study supported the proposed hypotheses, including a mechanism of psychological wellbeing partially mediating the relationship between physical fitness and academic achievement. The findings of this study support the importance of encouraging activities to promote both physical fitness and psychological wellbeing in schools.

The archaeology of the Northern Rio Grande region of New Mexico has recently received an increased amount scholarly attention. In particular, understanding past trends in demographics, agricultural productivity, violence, and social networks have been primary goals of archaeological research. Understanding patterns in animal exploitation has, however, received far less attention due to a small yet growing regional zooarchaeological database. Through the identification of animal remains from a site called Ponsipa (occupied ca. A.D. 1300 to 1600), this thesis adds one large dataset to this growing database. In addition, this thesis expands on the pre-impoundment distribution of an endangered native freshwater fish species in the state of New Mexico called the blue sucker (Cycleptus elongatus). The blue sucker is a unique fish that is currently experiencing range reduction across all of its known North American distribution due to anthropogenic habitat fragmentation and degradation. Skeletal remains that were identified from Ponsipa represent the farthest known northern record of its occurrence in the state of New Mexico and highlight the extent of range restriction of the species in the area. The data concerning the historical biogeography of the blue sucker from Ponsipa have implications for the effective conservation and restoration of blue sucker …

For many years newspapers were locally owned by editors and publishers. However, today many are run by corporations from out of state. As a result, many communities have lost the personal relationship between the family owned publication and the community. Gene Howe, who served as editor, publisher and columnist of the Amarillo Globe-News from 1926 until his death in 1952, believed the community was where the focus should be and the newspaper should do all that it can to help their readers. Despite the fact that Howe was not born in Amarillo, Texas, his passion and love for the city and its inhabitants compensated for it. During the Dust Bowl and Great Depression Howe and the Globe-News helped Amarillo survive the dust and economic storms that blew through the Texas Panhandle, an area that has not been written as much as other parts of Texas. Through his “Tactless Texan” column, which served as a pulpit to the community, to the various contests and promotions the newspaper sprang up, including the creation of Mother in Law Day, Gene Howe gave the newspaper another dimension little has been studied about, the role of the editor and publisher in guiding a community through …

This study investigates factors that can influence leaders to use plebiscites to settle territorial claims. A quick survey of the plebiscite literature shows that the method has been extensively mentioned in the legal, historical, and philosophical fields (mostly through case studies) but less so in political science. This thesis is the first attempt, to my knowledge, to quantitatively investigate the different factors that can influence a leader to use a plebiscite. Using the latest version of the ICOW dataset, I test political and economic theories to try to explain the variation in the decision outcome. This study includes the following variables: identity ties, economic strength, an interaction between identity ties and economic strength, internal constraints (regime type and violent interaction), and external constraints (membership to international organizations). The results suggest that identity ties offer the strongest explanation as to why leaders settle a territorial claim with a plebiscite. Plebiscites have been rarely used to settle territorial claims, but when used they tend to settle cases permanently. This thesis serves as an attempt to revive a method that while difficult to agree upon, can be successful in resolving territorial claims permanently, and more importantly peacefully.

Beginning in the 1970s, and aided by the advancement and an increased prevalence of computers, spectral music emerged as an important development in twentieth century music. Spectral composers, as exemplified by Gérard Grisey and Tristan Murail, took the harmonic spectra of sounds as the fundamental materials of composition. The resulting music placed an emphasis on texture and gradually evolving forms. The generation of composers immediately following the spectralists assimilated their techniques into distinct and varying styles. Finnish composer Kaija Saariaho uses spectral techniques to create an aesthetic that generates form and progression from a sound/noise axis. In her piece Du cristal…à la fumée, a number of pendulum and half-pendulum gestures build up texture and form. The accompanying original composition Axiom Unearthed employs similar pendulum gestures and uses spectral techniques to generate melody and harmony in an aesthetic divergent from traditional spectral pieces.

The poems in this collection are elegiac; celebrations of losses and failures, tributes to the daily doldrums that are at the center of human experience. They threaten to expose the uncertainty that exists and refuses to exist in our everyday lives. They explore the otherness associated with the individual and often turn to the universal formulas of music and physics to make order of the world around them. Often times the Speaker finds that the seeming chaos manifests within her already orderly life, the daily routines of work and family. Poetic magic, so to speak, weds this ordered chaos to the laws of nature and its routines, especially birds, which makes a recurrent appearance throughout the manuscript.

The purpose of this research was to examine the influence of fictitious scoring updates on psychological momentum (PM) and athletic performance in a competitive basketball setting. The participants included in this study were 50 male undergraduate students who reported having played basketball previously and qualified by being able to make more than 24% (12 out of 50) of their 3-point shots in a pre-trial session. Participants were told that they were competing in a 50 shot, 3-point shooting competition against another individual, equal in ability. After every 10 shots, participants were given a fabricated score update and answered four questions used to measure PM. Results showed that the fictitious score updates significantly (p < .01) influenced participants’ PM scores, where those who were told they led had higher PM scores than those who were told they trailed. As for shooting performance, no significant differences (p = .76) were found between positive and negative PM states for participants who reported experiencing both during the competition. Together, these findings suggest that manufactured score updates can influence PM, but resultant performance differences may not exist. Results of this study lend support to the notion that PM is experienced by athletes. However, when examining …

Collegiate and elite female athletes have been identified as a subpopulation at heightened risk for disordered eating and pathogenic weight management practices. It was hypothesized that this increases risk may be related to sport specific pressures (such as team conducted weigh-ins), or the use and frequency of self-weighing. It appears that mandatory, team conducted weigh-ins are not salient to female athletes in regards to experiencing internalization, body image concerns, dietary restraint, negative affect, and bulimic symptomatology. Results, however, indicate that frequency of engagement in self-weighing may be influential in the engagement of disordered eating symptoms. Specifically, athletes who weighed themselves three or more times per week reported significantly more internalization of general societal ideals and athletic body ideals. For body image concerns, athletes who weighed three or more times per week reported being more concerned with their body size/shape than all others. With respect to dietary behaviors, athletes who weighed themselves three or more times per week reported engaging in significantly more caloric restriction than did those who weighed less frequently. For negative affect, the athletes who weighed themselves three or more times per week reported significantly higher levels of both anger and guilt. Finally for bulimic symptomatology, athletes who …

Dating violence (DV) among young adults, specifically in college settings, is a serious issue with potential severe repercussions – both physically and psychologically – for victims of DV (DV victimization), and even financially on societal institutions as a whole. Exposure to parental intimate partner violence (IPV) has been associated with DV in young adults. Such violent behaviors appear to be associated with a recurrent pattern of aggressive thought processes, content, and arousing emotions. This study investigated the mediating effects of explicit socio-cognitive processes, through the reformulated social information processing (SIP) model, and implicit cognitive processes for exposure to parental IPV on DV perpetration and victimization, as well as the moderating effects of identification with parental figures and emotional arousal for exposure to parental IPV on predicting DV perpetration and victimization. 85 college students (men n = 23, M age = 22.29) were recruited for the study and results revealed that exposure to father-to-mother IPV predicted DV victimization, and that the interaction between exposure to father-to-mother IPV and identification with maternal figure predicted DV victimization. Conversely, identification with a parental figure negatively predicted DV victimization. The results revealed that SIP processes did not mediate the relationship for exposure to parental IPV …

While many investigations have been performed to establish a better understanding of the effects that magnetic fields and nanoparticles have on cells, the fundamental mechanisms behind the interactions are still yet unknown, and investigations on concurrent exposure are quite limited in scope. This study was therefore established to investigate the biological impact of concurrent exposure to magnetic nanoparticles and extremely-low frequency magnetic fields using an in-vitro CHO-K1 cell line model, in an easily reproducible manner to establish grounds for further in-depth mechanistic, proteomic, and genomic studies. Cells were cultured and exposed to 10nm Fe3O4 nanoparticles, and DC or low frequency (0Hz, 50Hz, and 100Hz) 2.0mT magnetic fields produced by a Helmholtz coil pair. The cells were then observed under confocal fluorescence microscopy, and subject to MTT biological assay to determine the synergistic effects of these concurrent exposures. No effects were observed on cell morphology or microtubule network; however, cell viability was observed to decrease more drastically under the combined effects of magnetic field and nanoparticle exposures, as compared to independent exposures alone. It was concluded that no significant difference was observed between the types of magnetic fields, and their effects on the nanoparticle exposed cells, but quite clearly there are …

The ritual music written for the Compline service of the Liturgy of the Hours, Into Your Hands, is analyzed using an ontological and phenomenological approach, which seeks to answer how such sound/musical phenomena wed to the specific ritual dynamics of Compline in their own right can create a potential for encounter with the Divine. The Jewish philosopher Martin Buber’s understanding of encounter is used to show that the sound/musical phenomena in itself bears similarities with the nature of the Judeo/Christian God, and such a nature is revealed to be both irreducibly non-conceptual as well as an entity that establishes the ontological actuality of one’s being. Studies in the beginnings of humanity at large as well as the beginnings of the individual fetus reveal that an integrated expression of music and ritual can be said to have formed the impetus of such ontological beginnings through encounter. Therefore, one of the first sounds heard in the womb - that of water (or amniotic fluid) - constitutes what may be an archetypal sound of encounter. The phenomenological effects of such an archetype are analyzed in the music of Into Your Hands through topics such as the loss of aural perspective, immersion, dynamic swells, …

The continued investigation into the experiences of individuals with schizophrenia who participate in biomedical research trials is necessary in order to understand participants’ perspectives, motivations, attitudes, values, and beliefs. As important stakeholders in the clinical research process, participant feedback is significant and can help shed light on, not only their experiences, but also deepen understandings when it comes to clinical trial participants’ perceptions of informed consent and personal autonomy. Conducting ethical research demands the exploration of these issues and specifically targeting this vulnerable group helped to address a gap in the literature. This study was conducted for InSite Clinical Research and gathered data in the form of in-depth semi-structured interviews and a short survey instrument with 20 low-income adults diagnosed with schizophrenia that participate in clinical research trials. Findings indicate overall positive research experiences, with motivations aligning with previous research when it comes to trial participation including: altruism, personal benefit, access to medications, financial incentives, and psychosocial treatment. Learning about their illness and themselves, autonomy, and debriefing were also particularly important within this group. Unique to this sample were findings of friendship. Trust in the research staff was identified as a major underlying value and shaping factor impacting informed consent …

Polymer nanocomposites are a going part of Materials Science and Engineering. These new composite materials exhibit dimensional and thermal stability of inorganic materials and toughness and dielectric properties of polymers. Development of nanocomposites become an important approach to create high-performance composite materials. In this study silica, fly ash, silica nanotubes and carbon black particles have been added to modify polyurethane foam and thermoplastic polyurethanes. It has been found that the addition of silica can diminish the size of foam bubbles, resulting in an increased stiffness of the material, increase of the compressive strength, and greater resistance to deformation. However, the uniformity of bubbles is reduced, resulting in increased friction of the material. Fly ash added to the foam can make bubbles smaller and improve uniformity of cells. Therefore, the material stiffness and compressive strength, resistance to deformation, and has little impact on the dynamic friction of the material. Adding nanotubes make bubble size unequal, and the arrangement of the bubble uneven, resulting in decreased strength of the material, while the friction increases. After the addition of carbon black to the polyurethane foam, due to the special surface structure of the carbon black, the foam generates more bubbles during the foaming …

The Barnett shale basin, the largest onshore gas field in the state of Texas, mainly produces natural gas. The basin’s oil and gas productions have dramatically increased over the past two decades with the enhancement via shale fracturing (fracking) technology. However, recent studies suggest that air emissions from shale fracking have significantly contributed to the growing air pollution problem in North Texas. In this study, air emissions from the Barnett shale basin during the production phase of the oil and gas activities (once the product is collected from the wells) are quantified. Oil and gas production data were acquired from the Texas Railroad Commission for the baseline years of 2010 through 2013. Methodology from prior studies on shale basins approved by the Texas Commission on Environmental Quality was employed in this study and the emission inventories from the production phase sources were quantified. Accordingly, the counties with the most gas operations in the basin, Tarrant, Johnson, Denton and Wise, were found to be the highest emitters of air pollutants. Tarrant County was responsible for the highest emitted NOx (42,566 tons) and CO (17,698 tons) in the basin, while Montague County released the maximum VOC emissions (87,601 tons) during the study …

The overall main goal of this research is to assist with the planning and creation of an ethnobotanical addition at the Heronswood Garden, a botanical garden located in northwest Washington state recently purchased by the Port Gamble S’Klallam Tribe. Methods included a three month long ethnographic study of Heronswood Garden as an official intern, and conducting a needs assessment that primarily employed participant observation and semi-structured open-ended interviews with all garden employees. Information revealed through the research includes causal issues behind a lack of community participation at the garden, elaboration on the solutions to various issues facilitated by negotiating and combining the views and opinions of the garden’s employees, and author reflections on the needs assessment report and the project as a whole. This research connects itself with and utilizes the methodologies and theories from applied anthropology, environmental anthropology, and environmental science to provide contemporary perspective into the subject of preserving or preventing the loss of biodiversity, language diversity, and sociocultural diversity.

Food selectivity exhibited by children with autism creates a myriad of barriers for families and children, ranging from social to nutritional. The typical approach to food selectivity is pathological. The pathological approach attempts to eliminate food selectivity through the use of techniques such as escape extinction. While successful in decreasing aspects of food challenges, such as food refusals, the pathological approach does not necessarily establish desired responses to foods or mealtimes (e.g., favorable affect, approach, generalized sampling, etc.). The purpose of the current study was to explore an alternative, constructional approach to food challenges presented by two children diagnosed with autism. This approach focuses on the development of favorable responses to food through the use of shaping. Furthermore, the shaping process involved a conceptual and procedural widening of the stimulus and response classes selected. The results of a non-concurrent multiple baseline experiment, suggest this approach was successful in expanding the number of food the children tasted and ate while maintaining favorable or neutral affect and child assent.

The formation of state borders is often told through the history of war and diplomacy. What is neglected is the tale of how borders of seemingly peaceful and long-extant places were set. In drawing Egypt’s borders, nineteenth-century cartographers were drawing upon a well of knowledge that stretched back into antiquity. Relying on the works of Greco-Roman writers and the Bible itself, cartographers and explorers used the authority of these works to make sense of unfamiliar lands, regardless of any current circumstances. The border with Palestine was determined through the usage of the Old Testament, while classical scholars like Herodotus and Ptolemy set the southern border at the Cataracts. The ancient cartography of Rome was overlaid upon the Egypt of Muhammad Ali. Given the increasing importance Egypt had to the burgeoning British Empire of the nineteenth century, how did this mesh with the influences informing cartographical representations of Egypt? This study argues that the imagined spaces created by Western cartographers informed the trajectory of Britain’s eventual conquest of Egypt. While receding as geopolitical concerns took hold, the classical and biblical influences were nonetheless part of a larger trend of Orientalism that colored the way Westerners interacted with and treated the people …

Throughout its current range, the Cross Timbers forest ecosystem is vulnerable to land-use change. In this study, we examined the surrounding land use matrix on the vegetation structure, composition and regeneration of six Cross Timbers forest fragments in Denton County, Texas (north of the Dallas-Fort Worth metroplex). Two fragments adjacent to agricultural land, two to residential neighborhoods, and two formally protected forest sites were selected. In summer 2015, five 100 m2 plots were randomly established in each fragment at least 200 meters from the edge. In each plot, all live and dead trees ≥ 3 cm diameter were identified and their height and diameter at breast height (DBH at 1.3 m aboveground) measured. Evidence of dumping (presence of trash) was recorded as an index of human frequentation. Differences in vegetation structure among the forest fragments were found. Most notably, fragments adjacent to agriculture contained 25% to 50% fewer trees per hectare than all other sites (Kruskal-Wallis, p < 0.02), especially trees <10 cm DBH. However, residential fragments had fewer trees that were ≥15 cm DBH compared to the other fragments, indicating that these are the youngest of the forest patches surveyed. Trash was observed in 60% of plots surveyed at …

In situations where information infrastructure is destroyed or not available, on-demand information infrastructure is pivotal for the success of rescue missions. In this paper, a drone-carried on demand information infrastructure for long-distance WiFi transmission system is developed. It can be used in the areas including emergency response, public event, and battlefield. The WiFi network can be connected to the Internet to extend WiFi access to areas where WiFi and other Internet infrastructures are not available. In order to establish a local area network to propagate WIFI service, directional antennas and wireless routers are used to create it. Due to unstable working condition on the flying drones, a precise heading turning stage is designed to maintain the two directional antennas facing to each other. Even if external interferences change the heading of the drones, the stages will automatically rotate back to where it should be to offset the bias. Also, to maintain the same flying altitude, a ground controller is designed to measure the height of the drones so that the directional antennas can communicate to each other successfully. To verify the design of the whole system, quite a few field experiments were performed. Experiments results indicates the design is reliable, …

A positive psychosocial intervention comprised of high autonomy support, task-involvement, and caring was implemented in physical activity classes to examine its effects on college women’s basic psychological needs (i.e. autonomy, competence, relatedness), exercise regulations (i.e. external, introjected, identified, integrated, intrinsic) and social physique anxiety (SPA). We hypothesized that at the end of the semester, participants in the intervention group (N = 73) would report greater need satisfaction, more self-determined regulations and less SPA than participants in the non-intervention group (N = 60). At T1 and T2, both the intervention and non-intervention participants reported “agreeing” with experiencing an autonomy supportive, task-involving, and caring environment. Furthermore, both groups at T1 and T2 reported moderate SPA. No significant group differences were found at T1. At T2, significant group differences were observed in the intervention and non-intervention groups’ report of external regulation and intrinsic regulation. The results suggests that group exercise instructors are capable of creating a positive psychosocial environment to enhance students’ intrinsic motivation.
