A study of the American Association of Retired Persons
Creators: name: Ingram, Lenora Gay
Publisher: name: University of Nevada, Las Vegas

description: This thesis presents a discussion of the role of a public interest group and the potential impact of its participation in the public policy arena. The particular interest group being assessed is the American Association of Retired Persons, AARP. An assessment shall be conducted through multiple factors. The first factor is the evolution of group theory in the discipline of political science. A second factor presents a historical path of the acknowledgement and development of interest groups in the United States. The remaining factors assess the interest group, AARP, as it relates to interest group theory and as it has evolved as an interest group existing in the American political structure. An evaluation is conducted in which AARP is viewed in respect to its unique characteristics of group size, financial base, leadership, and public policy involvement. The thesis is concluded with the belief that the American Association of Retired Persons has the potential to influence the direction of public policy in America because AARP has the internal structural elements to perpetuate as an organization; its membership, consisting of members fifty years and older, leads at the polls in voter turn-out; and because Americans are living longer, the membership roles of AARP are guaranteed to grow.

description: Statistical post-processing of dynamical forecast ensembles is an essential component of weather forecasting. In this article, we present a post-processing method that generates full predictive probability distributions for precipitation accumulations based on ensemble model output statistics (EMOS). We model precipitation amounts by a generalized extreme value distribution that is left-censored at zero. This distribution permits modelling precipitation on the original scale without prior transformation of the data. A closed form expression for its continuous rank probability score can be derived and permits computationally efficient model fitting. We discuss an extension of our approach that incorporates further statistics characterizing the spatial variability of precipitation amounts in the vicinity of the location of interest. The proposed EMOS method is applied to daily 18-h forecasts of 6-h accumulated precipitation over Germany in 2011 using the COSMO-DE ensemble prediction system operated by the German Meteorological Service. It yields calibrated and sharp predictive distributions and compares favourably with extended logistic regression and Bayesian model averaging which are state of the art approaches for precipitation post-processing. The incorporation of neighbourhood information further improves predictive performance and turns out to be a useful strategy to account for displacement errors of the dynamical forecasts in a probabilistic forecasting framework.

description: Ultimate storage rings (USRs), with electron emittance smaller than 100 pm.rad and on the scale of the diffraction limit for hard X-rays in both transverse planes, have the potential to deliver photons with much higher brightness and higher transverse coherence than that projected for the rings currently operational or under construction. Worldwide efforts have been made to design and to build light sources based on USRs. How to obtain a round beam, i.e. beam with equivalent transverse emittances, is an important topic in USR studies. In this paper, we show that a locally-round beam can be achieved by using a pair of solenoid and anti-solenoid with a circularly polarized undulator located in between. Theoretical analysis and application of this novel method, particularly to one of the Beijing Advanced Photon Source storage ring design having natural emittance of 75 pm.rad, are presented.

description: In this paper, we show how the MEP hypothesis may be used to build simple climate models without representing explicitly the energy transport by the atmosphere. The purpose is twofold. First, we assess the performance of the MEP hypothesis by comparing a simple model with minimal input data to a complex, state-of-the-art General Circulation Model. Next, we show how to improve the realism of MEP climate models by including climate feedbacks, focusing on the case of the water-vapour feedback. We also discuss the dependence of the entropy production rate and predicted surface temperature on the resolution of the model.

description: The observed population of the Milky Way satellite galaxies offer a unique testing ground for galaxy formation theory on small-scales. Our novel approach was to investigate the clustering of the known Milky Way satellite galaxies and to quantify the amount of substructure within their distribution using a two-point correlation function statistic in each of three spaces: configuration space, line-of-sight velocity space, and four-dimensional phase-space. These results were compared to those for three sets of subhaloes in the Via Lactea II Cold Dark Matter simulation defined to represent the luminous dwarfs. We found no evidence at a significance level above 2-sigma of substructure within the distribution of the Milky Way satellite galaxies in any of the three spaces. The "luminous" subhalo sets are more strongly clustered than are the Milky Way satellites in all three spaces and over a broader range of scales in four-dimensional phase-space. Each of the "luminous" subhalo sets are clustered as a result of substructure within their line-of-sight velocity space distributions at greater than 3-sigma significance, whereas the Milky Way satellite galaxies are randomly distributed in line-of-sight velocity space. While our comparison is with only one Cold Dark Matter simulation, the inconsistencies between the Milky Way satellite galaxies and the Via Lactea II subhalo sets for all clustering methods suggest a potential new 'small-scale' tension between Cold Dark Matter theory and the observed Milky Way satellites. Future work will obtain a more robust comparison between the observed Milky Way satellites and Cold Dark Matter theory by studying additional simulations.

description: Light management is of great importance to photovoltaic cells, as it determines the fraction of incident light entering the device. An optimal pn-junction combined with an optimal light absorption can lead to a solar cell efficiency above the Shockley-Queisser limit. Here, we show how this is possible by studying photocurrent generation for a single core-shell p-i-n junction GaAs nanowire solar cell grown on a silicon substrate. At one sun illumination a short circuit current of 180 mA/cm^2 is obtained, which is more than one order of magnitude higher than what would be predicted from Lambert-Beer law. The enhanced light absorption is shown to be due to a light concentrating property of the standing nanowire as shown by photocurrent maps of the device. The results imply new limits for the maximum efficiency obtainable with III-V based nanowire solar cells under one sun illumination.

description: La epigenética es el estudio de los mecanismos que producen modificaciones en la expresión génica, pero sin llegar a alterar la secuencia de nucleótidos de la molécula de ADN. Los principales mecanismos epigenéticos son la metilación del ADN, las modificaciones de las histonas y las alteraciones del ARN no codificante. La enfermedad de Alzheimer (EA) es un trastorno neurodegenerativo que se caracteriza por la pérdida progresiva de neuronas, produciéndose un deterioro cognitivo responsable de gran parte de las demencias en personas de edad avanzada. A día de hoy, se desconoce la causa exacta que desencadena esta enfermedad, aunque existen diversas hipótesis, siendo las más estudiadas la hipótesis amiloide y la hipótesis de la proteína Tau. En este trabajo se realiza un estudio bibliométrico para ver la relevancia y el crecimiento del campo de estudio. Posteriormente se buscan los marcadores implicados en las interacciones epigenéticas más estudiadas en la EA, como metilación de algunos genes relacionados con la enfermedad, la modificación de histonas que influyen en la transcripción de ciertos genes asociados a la patología y la regulación de determinados microARNs que se han visto involucrados en el desarrollo de la EA; siendo éste último un prometedor biomarcador porque los pacientes con EA presentan alteraciones de microARNs en cerebro, líquido cefalorraquídeo y sangre. También se describen dianas terapéuticas epigenéticas: inhibidores de la ADN metiltransferasa, inhibidores de la deacetilasa y algunos microARNs empleados como agentes terapéuticos. Por último, se evalúa la importancia de los factores ambientales en el desarrollo, analizando estudios sobre la influencia el déficit de vitamina B o la exposición al plomo, sobre determinados factores epigenéticos.

title: T-Count Optimization of Quantum Carry Look-Ahead Adder
Creators: name: Khalus, Vladislav Ivanovich
Publisher: name: University of Kentucky Libraries
Year: 2019

description: With the emergence of quantum physics and computer science in the 20th century, a new era was born which can solve very difficult problems in a much faster rate or problems that classical computing just can't solve. In the 21st century, quantum computing needs to be used to solve tough problems in engineering, business, medical, and other fields that required results not today but yesterday. To make this dream come true, engineers in the semiconductor industry need to make the quantum circuits a reality.
To realize quantum circuits and make them scalable, they need to be fault tolerant, therefore Clifford+T gates need to be implemented into those circuits. But the main issue is that in the Clifford+T gate set, T gates are expensive to implement.
Carry Look-Ahead addition circuits have caught the interest of researchers because the number of gate layers encountered by a given qubit in the circuit (or the circuit's depth) is logarithmic in terms of the input size n. Therefore, this thesis focuses on optimizing previous designs of out-of-place and in-place Carry Look-Ahead Adders to decrease the T-count, sum of all T and T Hermitian transpose gates in a quantum circuit.

description: The pseudorapidity density and anisotropic flow of charged-particles provide fundamental information about global variables and correlations in heavy-ion collisions. The pseudorapidity density is related to the energy available for particle production while the anisotropic flow is related to collective effects from interactions between these particles. Extending these measurements to very forward pseudorapidities yields information about the longitudinal expansion of the system. The first measurements performed at the LHC over more than 8 units of pseudorapidity are presented. The longitudinal scaling of the measurements is analyzed and comparison to models is performed.

The X-ray pulse profile resembles the modulation of hot spot on the surface of the neutron star. The phase-averaged spectral analysis also suggests that the majority of the observed X-rays have a thermal origin. This is the third member in the class of radio-quiet pulsars with the significant pulsations detected from both X-rays and gamma-ray regimes.

description: We make use of publicly available results from N-body Millennium Simulation to create mock samples of lensed supernovae type Ia and core-collapse. Simulating galaxy-galaxy lensing we derive the rates of lensed supernovae and find than at redshifts higher that 0.5 about 0.06 per cent of supernovae will be lensed by a factor two or more. Future wide field surveys like Gaia or LSST should be able to detect lensed supernovae in their unbiased sky monitoring. Gaia (from 2013) will detect at least 2 cases whereas LSST (from 2018) will see more than 500 a year. Large number of future lensed supernovae will allow to verify results of cosmological simulations. The strong galaxy- galaxy lensing gives an opportunity to reach high-redshift supernovae type Ia and extend the Hubble diagram sample.

description: We describe the procedure used to flux calibrate the three-band submillimetre photometer in the Spectral and Photometric Imaging REceiver (SPIRE) instrument on the Herschel Space Observatory. This includes the equations describing the calibration scheme, a justification for using Neptune as the primary calibration source, a description of the observations and data processing procedures used to derive flux calibration parameters (for converting from voltage to flux density) for every bolometer in each array, an analysis of the error budget in the flux calibration for the individual bolometers, and tests of the flux calibration on observations of primary and secondary calibrators. The procedure for deriving the flux calibration parameters is divided into two parts. In the first part, we use observations of astronomical sources in conjunction with the operation of the photometer internal calibration source to derive the unscaled derivatives of the flux calibration curves. To scale the calibration curves in Jy/beam/V, we then use observations of Neptune in which the beam of each bolometer is mapped using Neptune observed in a very fine scan pattern. The total instrumental uncertainties in the flux calibration for the individual bolometers is ~0.5% for most bolometers, although a few bolometers have uncertainties of ~1-5% because of issues with the Neptune observations. Based on application of the flux calibration parameters to Neptune observations performed using typical scan map observing modes, we determined that measurements from each array as a whole have instrumental uncertainties of 1.5%. This is considerably less than the absolute calibration uncertainty associated with the model of Neptune, which is estimated at 4%.

Improving Healthcare Financial Performance through Data-Driven Forecasting, Cost Modeling, and Reimbursement Optimization Tools
Creators: name: Okunuga, Aishat
Publisher: name: Zenodo
Year: 2025

description: In an era of rising healthcare costs, regulatory complexity, and value-based care models, healthcare organizations face mounting pressure to enhance financial sustainability without compromising quality. Traditional budgeting methods and retrospective financial assessments are proving insufficient in navigating the volatility of today’s healthcare landscape. This article explores how data-driven methodologies—specifically predictive forecasting, advanced cost modeling, and reimbursement optimization—are revolutionizing financial performance in the healthcare sector. At a broader level, predictive analytics enables organizations to anticipate shifts in patient volumes, resource utilization, and revenue cycles by leveraging historical data, real-time inputs, and machine learning algorithms. This foresight allows for dynamic budget adjustments, improved capacity planning, and better alignment of clinical operations with financial goals. Complementing this, advanced cost modeling techniques such as activity-based costing and marginal cost analyses offer granular insight into service-line profitability and resource consumption, enabling more informed strategic decisions. The article further examines how reimbursement optimization tools—such as automated coding validation, payer contract analytics, and claims denial prediction—enhance revenue integrity and reduce financial leakage. These technologies empower finance and revenue cycle teams to identify underpayments, streamline audit processes, and improve payer negotiations. Taken together, the integration of these tools supports a shift from reactive financial management to a proactive, intelligent approach. By embedding data-driven strategies into financial workflows, healthcare organizations can unlock efficiencies, reduce uncertainty, and drive long-term sustainability in an increasingly competitive and regulated environment.

description: We use hexagonal mesophases made of oil-swollen surfactant-stabilized tubes arranged on a triangular lattice in water and doped with metallic salts as templates for the radiolytic synthesis of nanostructures. The nanostructures formed in this type of soft matrix are bimetallic palladium-platinum porous nanoballs composed of 3D-connected nanowires, of typical thickness 2.5 nm, forming hexagonal cells. We demonstrate using electron microscopy and small-angle X-ray scattering that the pore size of the nanoballs is directly determined by the diameter of the oil tube of the doped mesophases, which we have varied in a controlled fashion from 10 to 55 nm. Bimetallic nanostructures comprising various proportions of palladium and platinum can be synthesized. Their alloy structure was evidenced by X-ray photoelectron spectroscopy, energy-dispersive X-ray spectroscopy, and high-angular dark field scanning transmission electron microscopy experiments. Our templating approach allows therefore the synthesis of bimetallic nanoballs of tunable porosity and composition.
title: Copula-Based Models for Bivariate and Multivariate Zero-inflated Count Time Series Data
Creators: name: Fernando, Dimuthu

Publisher: name: Old Dominion University Libraries
Year: 2023

description: Count time series data have multiple applications. The applications can be found in areas of finance, climate, public health and crime data analyses. In some scenarios, count time series come as multivariate vectors that exhibit not only serial dependence within each time series but also with cross correlation among the series. When considering these observed counts, analysis presents crucial challenges when a value, say zero, occurs more often than usual. There is presence of zero-inflation in the data.

In this presentation, we mainly focus on modeling bivariate zero-inflated count time series model based on a joint distribution of the two consecutive observations. The bivariate zero-inflated models are constructed through copula functions. Such Gaussian copula can accommodate both serial dependence and cross-sectional dependence in zero-inflated count time series data. We consider the first order Markov chains with zero-inflated Poisson (ZIP), zero-inflated negative binomial (ZINB) and zero-inflated Conway-Maxwell-Poisson (ZICMP) marginals. Bivariate copula functions such as the bivariate Gaussian and t-copula are chosen to construct the distribution of consecutive observations. Likelihood based inference is used to estimate the model parameters with the bivariate integrals of the Gaussian or t-copula functions being evaluated using standard randomized importance sampling method. To evaluate the superiority of the model, simulated (under positive and negative cross-correlations) are provided and presented. Real data examples are also shared.

Extensions for high dimensional scenarios are discussed by introducing the copula autoregressive model (COPAR) with pair copula construction and vine tree structure. Structure matrices of the COPAR of orders 1 and 2 are shown. Simulations are conducted to validate the models.

description: Foundational investigations in quantum mechanics, both experimental and theoretical, gave birth to the field of quantum information science. Nevertheless, the foundations of quantum mechanics themselves remain hotly debated in the scientific community, and no consensus on essential questions has been reached. Here, we present the results of a poll carried out among 33 participants of a conference on the foundations of quantum mechanics. The participants completed a questionnaire containing 16 multiple-choice questions probing opinions on quantum-foundational issues. Participants included physicists, philosophers, and mathematicians. We describe our findings, identify commonly held views, and determine strong, medium, and weak correlations between the answers. Our study provides a unique snapshot of current views in the field of quantum foundations, as well as an analysis of the relationships between these views.

description: In this paper, we propose a geometrical approach to mirror computation of genus 0 Gromov-Witten invariants of CP^2. We use multi-point virtual structure constants, which are defined as intersection numbers of a compact moduli space of quasi maps from CP^1 to CP^2 with 2+n marked points. We conjecture that some generating functions of them produce mirror map and the others are translated into generating functions of Gromov-Witten invariants via the mirror map. We generalize this formalism to open string case. In this case, we have to introduce infinite number of deformation parameters to obtain results that agree with some known results of open Gromov-Witten invariants of CP^2. We also apply multi-point virtual structure constants to compute closed and open Gromov-Witten invariants of a non-nef hypersurface in projective space. This application simplifies the computational process of generalized mirror transformation.

description: The characterization of the polarimetric properties of the planet Earth is important for the interpretation of expected observations and the planning of future instruments. We present a multi-wavelengths and multi-phase set of benchmark values for the polarization signal of the integrated light from the planet Earth derived from new polarimetric observations of the earthshine back-scattered from the Moon's dark side. Using a new, specially designed wide field polarimeter we measured the fractional polarization of the earthshine in the B, V, R and I filters for Earth phase angles alpha between 30° and 110°. The phase dependence of the earthshine polarization is fitted by a function p x sin(alpha)^2. To determine the polarization of the planet Earth we correct our earthshine measurements by a polarization efficiency function for the lunar surface derived from measurements of lunar samples from the literature. The polarization of the earthshine decreases towards longer wavelengths and is about a factor 1.3 lower for the higher albedo highlands. For mare regions the measured maximum polarization is about 13 % at quadrature in the B band. The resulting fractional polarizations for Earth are 24.6 % for the B band, 19.1 % for the V band, 13.5 % for the R band, and 8.3 % for the I band. Together with literature values for the spectral reflectivity of Earth we obtain a contrast between the polarized flux of the Earth and the (total) flux of the Sun with an uncertainty of less than 20 % and we find that the best phase to detect an Earth twin is around an Earth phase alpha=65°. The polarimetric models of Earth-like planets from Stam (2008) are in qualitative agreement with our results but there are also significant differences which might guide more detailed computations.

description: Iterated games are a fundamental component of economic and evolutionary game theory. They describe situations where two players interact repeatedly and have the possibility to use conditional strategies that depend on the outcome of previous interactions. In the context of evolution of cooperation, repeated games represent the mechanism of reciprocation. Recently a new class of strategies has been proposed, so called 'zero determinant strategies'. These strategies enforce a fixed linear relationship between one's own payoff and that of the other player. A subset of those strategies are 'extortioners' which ensure that any increase in the own payoff exceeds that of the other player by a fixed percentage. Here we analyze the evolutionary performance of this new class of strategies. We show that in reasonably large populations they can act as catalysts for the evolution of cooperation, similar to tit-for-tat, but they are not the stable outcome of natural selection. In very small populations, however, relative payoff differences between two players in a contest matter, and extortioners hold their ground. Extortion strategies do particularly well in co-evolutionary arms races between two distinct populations: significantly, they benefit the population which evolves at the slower rate - an instance of the so-called Red King effect. This may affect the evolution of interactions between host species and their endosymbionts.

Here we observe that, in vacuum, the required geometric condition is fulfilled by the well known maximal slicing, often used in numerical relativity. As a corollary, we establish that the Kerr geometry is a solution of n-DBI gravity in the foliation adapted to Boyer-Lindquist coordinates.

description: In selecting a route for the shipment of hazardous materials, the primary public safety concern is that routing minimizes risk by avoiding populated areas while utilizing the shortest and safest possible routes to reduce time in-state shipments; This research presents a methodology for estimating population index which reflects density ranges for various population groupings. The population index is based on the number of tracts, tract density, and county density. The population index is initially defined for population {dollar}{dollar}8000. in the absence of more data to validate the results in the latter grouping, the index is redefined for population {dollar}<{dollar}2500 and population {dollar}\geq{dollar}2500. The index is used to determine the level of analysis required in evaluating population: county, tract, or block level; Routing analysis based on minimization of risk by minimizing affected population is performed for the state of Nevada. The analysis focuses on two alternative rail routes that are being considered by the Department of Energy (DOE) for the shipment of high level wastes and spent nuclear fuels.

description: We consider the first appearance of vortices in a two-dimensional (2-D) superconducting film exposed to a non-uniform magnetic field, $\mathbf{B_a}$, produced by a nearby coil. The film has "infinite" radius, $R_f$, and thickness $t$ about equal to the coherence length, $ξ$. The coil is approximated as a point dipole. We find that the first vortex-bearing state to appear has both a vortex and an antivortex. The Gibbs free energy of this state is lower than the vortex-free state when the applied perpendicular field, $B_0$, at the origin exceeds the external critical field: $B_{c1}^0 = \frac{4\sqrt{2}Λ}{R}\frac{Φ_0}{4πΛ^2}ln\left(\fracΛξ\right)$, where $\frac{Φ_0}{4πΛ^2}ln\left(\fracΛξ\right) \equiv B_{c1}^{2D}$ is the intrinsic critical field in 2-D, $Λ\equiv 2λ^2/t$ the 2-D penetration depth introduced by Pearl, and $λ$ is the bulk penetration depth. The prefactor, $4\sqrt{2}Λ/R$, is calculated in the strong-screening regime, $Λ/R \ll 1$. $R$ is the radial distance at which the applied perpendicular field, $B_{a,z}(ρ)$, changes sign. In the lab, the onset of vortex effects generally occurs at a field much higher than $B_{c1}^0$, indicating that vortices are inhibited by the vortex-antivortex unbinding barrier, or by pinning.

description: Objective: In this study, we determined whether Helicobacter pylori (H. pylori) infection dampens the efficacy of cancer immunotherapies. Design: Using mouse models, we evaluated whether immune checkpoint inhibitors or vaccine-based immunotherapies are effective in reducing tumour volumes of H. pylori-infected mice. In humans, we evaluated the correlation between H. pylori seropositivity and the efficacy of the programmed cell death protein 1 (PD-1) blockade therapy in patients with non-small-cell lung cancer (NSCLC). Results: In mice engrafted with MC38 colon adenocarcinoma or B16-OVA melanoma cells, the tumour volumes of non-infected mice undergoing anticytotoxic T-lymphocyte-associated protein 4 and/or programmed death ligand 1 or anti-cancer vaccine treatments were significantly smaller than those of infected mice. We observed a decreased number and activation status of tumour-specific CD8+ T cells in the tumours of infected mice treated with cancer immunotherapies independent of the gut microbiome composition. Additionally, by performing an in vitro co-culture assay, we observed that dendritic cells of infected mice promote lower tumour-specific CD8+ T cell proliferation. We performed retrospective human clinical studies in two independent cohorts. In the Dijon cohort, H. pylori seropositivity was found to be associated with a decreased NSCLC patient survival on anti-PD-1 therapy. The survival median for H. pylori seropositive patients was 6.7 months compared with 15.4 months for seronegative patients (p=0.001). Additionally, in the Montreal cohort, H. pylori seropositivity was found to be associated with an apparent decrease of NSCLC patient progression-free survival on anti-PD-1 therapy. Conclusion: Our study unveils for the first time that the stomach microbiota affects the response to cancer immunotherapies and that H. pylori serology would be a powerful tool to personalize cancer immunotherapy treatment.

description: We study the properties of eigenvalues and eigenvectors of the Google matrix of the Wikipedia articles hyperlink network and other real networks. With the help of the Arnoldi method we analyze the distribution of eigenvalues in the complex plane and show that eigenstates with significant eigenvalue modulus are located on well defined network communities. We also show that the correlator between PageRank and CheiRank vectors distinguishes different organizations of information flow on BBC and Le Monde web sites.

A cross-sectional study of the willingness to consume insects in a culture without entomophagy

description: Abstract: Entomophagy is the technical term for eating insects and traditionally a part of daily diet in many tropical and subtropical countries. The rapidly increasing world population, industry and human-induced environmental pollution, and global warming reduce agricultural lands and clean water resources and make it difficult to produce sufficient food and therefore protein. Although edible insects are a promising opportunity as they require fewer natural resources than other animal foods, they are not considered as the food of the future in many Western countries for reasons such as disgust. A growing body of research in a diverse array of cultural contexts has examined people’s attitudes towards eating insects, but this work has not yet included Türkiye, a country with a well-established traditional cuisine and where entomophagy is highly novel. This study examined attitudes toward eating insects, and predictors thereof, in a large Turkish community sample (n = 914). For willingness to eat whole insects, age was a significant positive predictor, and food neophobia, disgust sensitivity, and being female were negative predictors for both whole insects and insect flour foods. For both types of insect foods, disgust was a negative predictor and belief in the benefits of eating insects was a positive predictor. This pattern of results is concordant with work from many other cultural contexts in the Americas, Asia, and Western Europe, providing further evidence for the importance of reducing food neophobia and disgust sensitivity and providing information about the benefits of insect foods in order to improve attitudes toward entomophagy.
Meanings and measures taken in concert observation of Bruce Springsteen, September 28, 1992, Los Angeles
Creators: name: Rodak, Thomas J
Publisher: name: University of Nevada, Las Vegas

description: Since the mid-1970s, Bruce Springsteen's concerts and his rapport with audience members have attracted the attention of leading rock music critics. Witnessing the communication between Springsteen and audience members was the purpose of this study. On-site observation was used to explore the techniques that Springsteen uses to communicate with the audience during the concert; A model, previously employed by Deanna and Timothy Sellnow to determine the effects of musical score upon the lyrics of songs recorded in the studio, was utilized with the on-site observation. The model had not been applied to a concert performance before this study; The findings of this study identify the major measures and means Springsteen employs to diminish the distance between performer and members of the audience. The means he implemented are divided into performance aspects and musical aspects of the concert. Some of his strategies have since been emulated by other rock music performers, making this study of Springsteen an important addition to the field of communication by means of music.

description: The QR factorization and the SVD are two fundamental matrix decompositions with applications throughout scientific computing and data analysis. For matrices with many more rows than columns, so-called "tall-and-skinny matrices," there is a numerically stable, efficient, communication-avoiding algorithm for computing the QR factorization. It has been used in traditional high performance computing and grid computing environments. For MapReduce environments, existing methods to compute the QR decomposition use a numerically unstable approach that relies on indirectly computing the Q factor. In the best case, these methods require only two passes over the data. In this paper, we describe how to compute a stable tall-and-skinny QR factorization on a MapReduce architecture in only slightly more than 2 passes over the data. We can compute the SVD with only a small change and no difference in performance. We present a performance comparison between our new direct TSQR method, a standard unstable implementation for MapReduce (Cholesky QR), and the classic stable algorithm implemented for MapReduce (Householder QR). We find that our new stable method has a large performance advantage over the Householder QR method. This holds both in a theoretical performance model as well as in an actual implementation.
Deception detection accuracy: The effects of suspicion and antisocial personality traits
Creators: name: Schoephoerster, Barbara T

description: Previous research has indicated that moderate levels of suspicion will enhance deception detection accuracy. This study hypothesized that combining state suspicion and trait suspicion (i.e. antisocial personality traits) in order to create a moderate level of suspicion overall would produce a higher detection accuracy than would be found among individuals who were not suspicious. Participants consisted of 133 UNLV undergraduates, who completed the Antisocial subscale of the Millon Clinical Multiaxial Inventory-II. Participants were assigned to a no suspicion or moderate suspicion condition, viewed a videotape of persons being truthful or deceptive, judged videotape actors as being truthful or untruthful, and rated their own degree of suspicion. Results did not confirm the original hypothesis, but did indicate that persons high in antisocial traits were more suspicious than those low in such traits, and subjects not primed to be suspicious made more veracity judgments than those who were primed to be suspicious.
