The Mystical Experience and Its Neural Correlates
Abstract: Despite their different etiologies, three types of spiritually transformative experiences (STEs)--near-death experiences, psilocybin experiences, and meditative experiences of cosmic consciousness--appear to have attributes that are common to a broad range of mystical experiences, including an experience of expanded awareness. In addition, all three appear to be associated with profound and lasting transformations in the lives of experiencers. Finally, these three experiences appear to share some common neural correlates. In this article, we discuss similarities in case studies of these STEs, in data from controlled clinical research studies on their transformative effects, as well as from neurophysiological data correlated with the occurrence of STEs themselves. In all three STEs, research shows a reduction in neural activity in the major centers of the brain, including the Default Mode Network, the foundation of egoic stories involving the narrative related to oneself and the world in which one lives. It is proposed that during these STEs, reduced neural activity in areas of the brain that normally act as a filter or reducing valve mechanism opens the capacity to expanded awareness, which is associated with lasting transformation in the lives of experiencers.

The Significance of Autoscopies as a Time Marker for the Occurrence of Near-Death Experiences
Abstract: The physiological and psychological underpinnings of near-death experiences (NDEs) are not yet understood. In this article, we show that for "critical" NDEs reported after cardiac arrest, two different neurophysiological models have been proposed that, in the literature so far, have not been adequately distinguished from each other. In the real-time model, it is postulated that during critical NDEs, residual activities in the cerebrum were sufficient to generate NDEs in real time. In the reconstruction model, it is assumed that due to severe oxygen deficiency, critical NDEs could not have occurred at the time in question but were reconstructed later during the regeneration phase of the brain. To assess the plausibility of these two models, we analyzed the phenomenology of the view of one's own body from above (autoscopy) that frequently occurs in the beginnings of NDEs. In addition to the available literature, we used original descriptions of autoscopies obtained in an online survey conducted in 2015. We found that the reconstruction model is not supported by empirical findings and that some findings even speak against it. We therefore conclude that future discussions of explanatory models of NDEs should focus primarily on the neurophysiological real-time model and a third alternative …

Wingate Miniature Printing Press
This 3D dataset model contains the individual datasets necessary to print and assemble a miniature working printing press. The resulting press has a working area of about 2.35" X 1.7", stands 6.5" tall by 3.85" wide, and is 6" long. With minor liberties, this model is a miniature working version of a European style common press similar to those used during the hand-press era, in which a screw transmits pressure through the platen to create an even imprint onto an inked surface. Assembly is facilitated by downloading the related pdf file illustrating the individual press parts. Additional assistance is available at 3Dhotbed.info.

Activation of Small Molecules by Transition Metal Complexes via Computational Methods
The first study project is based on modeling Earth abundant 3d transition-metal methoxide complexes with potentially redox-noninnocent ligands for methane C–H bond activation to form methanol (LnM-OMe + CH4 → LnM–Me + CH3OH). Three types of complex consisting of tridentate pincer terpyridine-like ligands, and different first-row transition metals (M = Ti, V, Cr, Mn, Fe, Co, Ni, and Cu) were modeled to elucidate the reaction mechanism as well as the effect of the metal identity on the thermodynamics and kinetics of a methane activation reaction. The calculations showed that the d electron count of the metal is a more significant factor than the metal's formal charge in controlling the thermodynamics and kinetics of C–H activation. These researches suggest that late 3d-metal methoxide complexes that favor σ-bond metathesis pathways for methane activation will yield lower barriers for C–H activation, and are more profitable catalyst for future studies. Second, subsequently, on the basis of the first project, density functional theory is used to analyze methane C−H activation by neutral and cationic nickel-methoxide complexes. This study identifies strategies to further lower the barriers for methane C−H activation through evaluation of supporting ligand modifications, solvent polarity, overall charge of complex, metal identity and counterion …

The Adaptation of Saxophone-Like Phrasing into the Improvisatory and Compositional Vocabulary of Jazz Guitar: A Comparative Analysis of Phrasing, Articulation, and Melodic Design in the Styles of Jimmy Raney, Jim Hall, and John Scofield
This study investigates how different guitarists introduced saxophone-like phrasing into the improvisatory and compositional vocabulary of jazz guitar through their collaborations with saxophonists. This research presents a comparative analysis of phrasing, articulation, and melodic design in solo improvisations. The mixed approach to this study includes analysis of motives, voice leading, articulation, length of phrases, melodic contour, and the execution of bebop vocabulary on the guitar. The findings are based on original transcriptions from significant recordings by guitar-saxophone pairs. These highlight the similarities between and adaptations of musical devices from saxophonists Stan Getz, Jimmy Giuffre, and Joe Lovano into the jazz guitar styles of Jimmy Raney, Jim Hall, and John Scofield. This study supports the argument that the evolution of modern jazz guitar playing is directly connected to the adaptation of saxophone-like phrasing at an improvisatory and compositional level. It also shows that the concept of style in jazz flows between different instruments' lineages. Understanding these findings provides a more complex and accurate concept of the development of style in jazz.

The Administration of Unemployment Relief by the State of Texas during the Great Depression, 1929-1941
During the Great Depression, for the first time in its history, the federal government provided relief to the unemployed and destitute through myriad New Deal agencies. This dissertation examines how "general relief" (direct or "make-work") from federal programs—primarily the Emergency Relief and Construction Act (ERCA) and Federal Emergency Relief Administration (FERA)—was acquired and administered by the government of Texas through state administrative agencies. These agencies included the Chambers of Commerce (1932-1933), Unofficial Texas Relief Commission (1933), Texas Rehabilitation and Relief Commission (1933), Official Texas Relief Commission (1933-1934), Texas Relief Commission Division of the State Board of Control (1934), and the Department of Public Welfare (1939). Overall, the effective administration of general relief in the Lone Star State was undermined by a political ideology that persisted from, and was embodied by, the "Redeemer" Constitution of 1876.

Adolescent Self-Theories of Singing Ability within the Choral Hierarchy
The purpose of this study was to explore adolescent self-views of singing ability through both implicit theories and self-concept meaning systems. A secondary purpose of this study was to examine these self-views specifically in the context of a choral hierarchy. Using a researcher-designed survey instrument, I gathered data from middle- and high-school students currently enrolled in a choir program organized in a hierarchical structure. I analyzed descriptive statistics of survey responses to items designed to measure implicit theories of singing ability, singing self-concept, and goal orientation. I also examined differences among participants by ensemble placement in implicit theory and self-concept scores, correlation between implicit theory and self-concept, and whether implicit theory, self-concept, goal orientation, or current enrollment could predict future enrollment decisions. In addition to these quantitative measures, I coded open-ended responses to two failure scenarios and examined participant responses by ensemble and gender. Both implicit theory and self-concept scores were higher for participants at the top of the choral hierarchy than at the bottom. Open-ended responses, however, did not align with the implicit theory scale and a number of students presented a false growth mindset. Open-ended responses also indicated that failure scenarios were likely to result in an altered …

Analysis of Interrelationships between Climate Change and Cotton Yield in Texas High Plains
The Texas High Plains produces the most substantial amount of cotton in Texas. The region is a semi-arid area with limited precipitation, and it is, therefore, susceptible to climate change. Cotton production in the Texas High Plains is mostly dependent on irrigation to increase yield. The overall goal of this research was to study the interrelationships between climate change and cotton yield using correlation analysis and also to study how climate has changed in the region using trend analysis. A three-decade data (1987-2017) was analyzed to establish the relationship between climate change and cotton and also to determine how climate has changed in the area over the last 30 years. The research used precipitation and temperature data to assess climate change.The results of this research showed that annual mean temperature has lesser impacts on cotton yield, and the correlation between annual precipitation and cotton yield is insignificant. It also found out that high rates of temperature at the boll opening stage of cotton growth results in decreased cotton yield and that at the boll development and boll opening stages, precipitation is needed. Again, the research indicated that, on average, there had been a significant increase in temperature, but precipitation trends …

An Analysis of the Flypaper and Fungibility Effects of Intergovernmental Revenue on Municipal Operating and Capital Budgets
The flypaper effect states that grants-in-aid increases public spending more than a comparable increase in personal income. If aid increases spending, then there is the possibility that it displaces own-source revenue or a portion of the aid itself is used to meet other priorities of governments, fungibility. Different local government structures have the tendency to prioritize either the operating or capital budget. Empirical evidence shows that federal and state grants have different flypaper effect. While fungible state aid is allocated to the operating budget, that of federal goes to the capital budget. Council-manager and mayor-council form of governments do not allocate fungible intergovernmental aid differently between the capital and operating budgets.

An Analytical Survey of Hendrik Hofmeyr's Compositions for Solo Saxophone
Hendrik Hofmeyr is considered one of the most important and influential living composers in South Africa. His music for solo saxophone is not well-known in the classical saxophone repertoire. His four works for solo saxophone (Concerto per saxofono contralto e orchestra, Concerto per saxofono baritono e orchestra, Partita canonica, and Necromancer) are substantial and terrific repertoire for the instrument. This study is intended to inform a saxophone performer's understanding of these compositions through analysis of form, melodic, and harmonic content relevant to performance; and, demonstrate through example the conclusions determined by the analysis about apparent compositional techniques in the music.

Anxiety in the Workplace: A Study of Different Anxiety Relief Methods for Hotel Employees
There is a lack of anxiety relief methods used in the hospitality workplace. This study examines the effectiveness of two forms of anxiety relief through four different methods. The data collection took place in classroom environments at the University of North Texas and the University of New Orleans, both of which are located in southern USA. The independent variables are the recovery method, the mediator variables are restorativeness and emotional improvement, and the dependent variables are negative job affects, positive job affects, turnover intention, and job commitment. Professors were asked for some time during their lecture to conduct the experiment in a classroom environment during the students' class time. Eight classes were visited, with each class being exposed to a designated anxiety relief method. The anxiety relief methods consisted of using a virtual reality headset with sound, virtual reality headset without sound, nature pictures with sound, and nature pictures without sound. Results of 206 usable surveys indicated virtual reality recovery method evoked higher levels of restorativeness than picture recovery method. Restorativeness partially mediated the effects of positive job affects and job commitment. lastly, emotional improvement partially mediated the effects of negative job affects, positive job affects, and turnover intention.
