Buried Treasure: A Business Librarian’s Insights on Finding the Evidence
Creators: name: Roye Werner
Publisher: name: Carnegie Mellon University
Year: 2012
Subjects: subject: Library and Information Studies
subject: FOS: Media and communications

description: This chapter offers my perspective as a professional librarian and former manager on accessing the research evidence in the business and management fields. I describe the barriers faced by managers, students, and scholars in locating and reading the peer-reviewed literature: its scattered placement, varying formats, controlled access, and swiftly changing environment. I explore how those roadblocks are being overcome, and I offer practical recommendations for both managers and researchers on what they can do today to bring that evidence to light.
Large N Reductions and Holography

Year: 2005
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: The large $N$ reductions in gauge theories are identified with dimensional reductions with homogeneous distribution of the eigenvalues of the gauge field, and it is used to identify the corresponding closed string descriptions in the Maldacena duality. When one does not take the zero-radii limit, the large $N$ reductions are naturally extended to the equivalences between the gauge theories and the "generalized" reduced models, which naturally contain the notion of T-dual equivalence. In the dual gravitational description, T-duality relates two type IIB supergravity solutions, the near horizon geometry of D3-branes, and the near horizon geometry of D-instantons densely and homogeneously distributing on the dual torus. This is the holographic description of the generalized large $N$ reductions. A new technique for calculating correlation functions of local gauge invariant single trace operators from the reduced models is also given.

description: Radicalization is the process by which people come to adopt increasingly extreme political or religious ideologies. While radical thinking is by no means problematic in itself, it becomes a threat to national security when it leads to violence. We introduce a simple compartmental model (similar to epidemiology models) to describe the radicalization process. We then extend the model to allow for multiple ideologies. Our approach is similar to the one used in the study of multi-strain diseases. Based on our models, we assess several strategies to counter violent extremism.

description: This paper is aimed at analyzing the existence and convergence of approximate solutions in shape optimization. Two questions arise when one applies a Ritz-Galerkin discretization to solve the necessary condition: does there exists an approximate solution and how good does it approximate the solution of the original infinite dimensional problem? We motivate a general setting by some illustrative examples, taking into account the so-called two norm discrepancy. Provided that the infinite dimensional shape problem admits a stable second order optimizer, we are able to prove the existence of approximate solutions and compute the rate of convergence. Finally, we verify the predicted rate of convergence by numerical results.

description: Recently, Bauke and Mertens conjectured that the local statistics of energies in random spin systems with discrete spin space should in most circumstances be the same as in the random energy model. This was proven in a large class of models for energies that do not grow too fast with the system size. Considering the example of the generalized random energy model, we show that the conjecture breaks down for energies proportional to the volume of the system, and describe the far more complex behavior that then sets in.
Recruiting Content for the Institutional Repository: The Barriers Exceed the Benefits
Creators: name: Troll, Denise

Subjects: subject: Library and Information Studies
subject: FOS: Media and communications

description: Focus groups conducted at Carnegie Mellon reveal that what motivates many faculty to self-archive on a website or disciplinary repository will not motivate them to deposit their work in the institutional repository. Recruiting a critical mass of content for the institutional repository is contingent on increasing awareness, aligning deposit with existing workflows, and providing value-added services that meet needs not currently being met by other tools. Faculty share concerns about quality and the payoff for time invested in publishing and disseminating their work, but disagree about metrics for assessing quality, the merit of disseminating work prior to peer review, and the importance of complying with publisher policies on open access. Bridging the differences among disciplinary cultures and belief systems presents a significant challenge to marketing the institutional repository and developing coherent guidelines for deposit.

description: Creosote bush (Larrea tridentata; LT) leaves extracts were tested for their potential efficacy to mitigate cellular oxidative stress on human SH-SY5Y cells. Here, the differential nuclear staining assay, a bioimager system, and flow cytometric protocols, concurrently with several specific chemicals, were used to measure the percentage of cell viability and several facets implicated in the cytoprotective mechanism of LT extracts. Initially, three LT extracts, prepared with different solvents, ethanol, ethanol:water (e/w), and water, were tested for their capacity to rescue the viability of cells undergoing aggressive H2O2-induced oxidative stress. Results indicate that the LT extract prepared with a mixture of ethanol:water (LT-e/w; 60:40% v/v) displayed the most effective cytoprotection rescue activity. Interestingly, by investigating the LT-e/w mechanism of action, it was found that LT-e/w extract decreases the levels of H2O2-provoked reactive oxidative species (ROS) accumulation, mitochondrial depolarization, phosphatidylserine externalization, caspase-3/7 activation, and poly (ADP-ribose) polymerase (PARP) cleavage significantly, which are hallmarks of apoptosis. Thus, out of the three LT extracts tested, our findings highlight that the LT-e/w extract was the most effective protective reagent on SH-SY5Y cells undergoing oxidative stress in vitro, functioning as a natural anti-apoptotic extract. These findings warrant further LT-e/w extract examination in a holistic context.

description: The classical Blandford & Payne (1982) model for the magnetocentrifugal acceleration and collimation of a disk-wind is revisited and refined. In the original model, the gas is cold and the solution is everywhere subfast magnetosonic. In the present model the plasma has a finite temperature and the self-consistent solution of the MHD equations starts with a subslow magnetosonic speed which subsequently crosses all critical points, at the slow magnetosonic, Alfven and fast magnetosonic separatrix surfaces. The superfast magnetosonic solution thus satisfies MHD causality. Downstream of the fast magnetosonic critical point the poloidal streamlines overfocus towards the axis and the solution is terminated. The validity of the model to disk winds associated with young stellar objects is briefly discussed. ~

description: We consider the dynamics of infinite harmonic lattices in the limit of the lattice distance epsilon tending to 0. We allow for general polyatomic crystals but assume exact periodicity such that the system can be solved in principle by Fourier transform and linear algebra. Our aim is to derive macroscopic continuum limit equations for epsilon --> 0. For the weak limit of displacements and velocities we find the equation of linear elastodynamics, where the elasticity tensor is obtained as a Gamma-limit. The weak limit of the local energy density can be described by generalizations of the Wigner-Husimi measure which satisfies a transport equation on the product of physical space and Fourier space. The concepts are illustrated via several examples and via a comparison to Whitham's modulation equation.

description: A study of the optical properties of a set of InAsxSb1-x/Al0.15In0.85As0.77Sb0.23/GaSb multiple quantum-wells (for x between 0.82 and 0.92) with build-in strains in the -0.62% to +0.05%-range is presented. The energy of the lowest quantum-confined optical transition is calculated by kp perturbation theory and experimentally determined by absorption measurements. Stokes shift of photoluminescence, photocurrent and of the emission from light emitting devices against the absorption edge of the quantum-well are quantified. The impact of the decreasing carrier confinement in the InAsxSb1-x quantum well system with increasing mole fraction is analyzed theoretically, and experimentally demonstrated by photoluminescence measurement. Our results allow for the improvement of optoelectronic devices, in particular for tailoring emission spectra of light emitting diodes.

description: In the present paper we consider the numerical solution of shape optimization problems which arise from shape functionals of integral type over a compact region of the unknown domain, especially $L^2$-tracking type functionals. The underlying state equation is assumed to satisfy a Poisson equation with Dirichlet boundary conditions. We proof that the shape Hessian is not strictly $H^1/2$-coercive at the optimal domain which implies ill-posedness of the optimization problem under consideration. Since the adjoint state depends directly on the state, we propose a coupling of finite element methods (FEM) and boundary element methods (BEM) to realize an efficient first order shape optimization algorithm. FEM is applied in the compact region while the rest is treated by BEM. The coupling of FEM and BEM essentially retains all the structural and computational advantages of treating the free boundary by boundary integral equations.

description: Quasinormal frequencies of electromagnetic and gravitational perturbations in asymptotically AdS spacetime can be identified with poles of the corresponding real-time Green's functions in a holographically dual finite temperature field theory. The quasinormal modes are defined for gauge-invariant quantities which obey incoming-wave boundary condition at the horizon and Dirichlet condition at the boundary. As an application, we explicitly find poles of retarded correlation functions of R-symmetry currents and the energy-momentum tensor in strongly coupled finite temperature N=4 supersymmetric SU(Nc) Yang-Mills theory in the limit of large Nc.

description: In the late nineteenth century, Spain had the highest percentage of sightless people of any nation in Europe, thus offering writers of the Realist period a vast panorama from which they could draw upon for the creation of similarly afflicted fictional characters.1 While the blind characters in Galdós’s novels and Episodios Nacionales have already been studied, to date there has been no study of the blind stock character of sightless street musicians in the nineteenth-century short story.2 The purpose of the present study is to initiate investigation of this tipo costumbrista by focusing on Palacio Valdés’s “El Pájaro en la nieve”—which received some praise from Juan Valera,3 but only superficial mention by Baquero Goyanes in his monumental El cuento español en el siglo XIX: “[A]unque ligeramente sensiblón y cargado de tópicos, es un buen cuento de su género y estilo, y significa la estilización del tema romántico y lastimoso del ciego en la nieve” (417).

description: The antiferromagnetically (AFM) ordered state of GdRh$_{2}$Si$_{2}$ which consists of AFM-stacked ferromagnetic layers is investigated by magnetic resonance spectroscopy. The almost isotropic Gd$^{3+}$ paramagnetic resonance becomes anisotropic in the AFM ordered region below 107 K. The emerging internal anisotropic exchange-fields are still small enough to allow an investigation of their magnetization dynamics by using a standard microwave-frequency magnetic resonance technique. We could characterize this anisotropy in detail in the ferromagnetic layers of the excitation at 9 and 34 GHz. We derived a resonance condition for the AFM ordered phase to describe the weak in-plane anisotropic behaviour in combination with a mean-field analysis.

description: We study the continuous-wave (CW) operation of a semiconductor laser subject to optical feedback from a Fabry-Perot resonator in a case where the emission is resonant to a reflection minimum of the resonator. This configuration is treated in the framework of Lang-Kobayashi equations. The nature of bifurcations and the stability of steady state solutions is analyzed in dependence on magnitude and phase of the feedback. In contrast to conventional optical feedback from a single mirror, the locus of external cavity modes is no more elliptic but represents a tilted eight with possible satellite bubbles. Below a critical feedback strength, which is analytically given, only one single mode exists representing the completely unchanged CW emission of the laser. In this weak-feedback regime, the feedback phase allows a noninvasive control of the CW emission and a tailoring of its small-signal response within wide limits. The obtained results are prototype for all-optical realizations of delayed feedback control.

description: Risk management technology applied to high dimensional portfolios needs simple and fast methods for calculation of Value-at-Risk (VaR). The multivariate normal framework provides a simple off-the-shelf methodology but lacks the heavy tailed distributional properties that are observed in data. A principle component based method (tied closely to the elliptical structure of the distribution) is therefore expected to be unsatisfactory. Here we propose and analyze a technology that is based on 1) performing an Independent Component (IC) search and 2) adaptively fitting the resulting independent marginals by Generalized Hyperbolic (GH) distributions. We study the proposed GHICA methodology in an extensive simulation study. We then apply GHICA to exchange rate portfolios with different trading strategies and a high-dimensional German stocks portfolio. Our analysis with GHICA yields very accurate VaRs.

description: En la escritura de José Martí se identifica un relato que se considera un proyecto fundacional o un plan de modernidad para los países de la América hispana. En estos “países azules,” como los llamó Martí (18: 205), la modernidad se manifestó tan a destiempo del resto de occidente que Jesús Martín-Barbero la ha llamado “tardomodernidad” (11). Esta tardomodernidad no sólo fue asincrónica con las demás modernidades sino que también lo fue entre sus partes. Los aspectos materiales de su cultura no aparecieron al mismo tiempo que su temprano lado estético: el modernismo. Las naciones emergentes de la América hispana desarrollaron un temprano sentido moderno de nacionalidad aunque con grandes incertidumbres acerca de sus respectivos futuros (Anderson 32).

description: The primary goal of cytokinesis is to produce two daughter cells, each having a full set of chromosomes. To achieve this, cells assemble a dynamic structure between segregated sister chromatids called the contractile ring, which is made up of filamentous actin, myosin-II, and other regulatory proteins. Constriction of the actomyosin ring generates a cleavage furrow that divides the cytoplasm to produce two daughter cells. Decades of research have identified key regulators and underlying molecular mechanisms; however, many fundamental questions remain unanswered and are still being actively investigated. This review summarizes the key findings, computational modeling, and recent advances in understanding of the molecular mechanisms that control the formation of the cleavage furrow and cytokinesis

description: Color transparency is the vanishing of initial and final state interactions, predicted by QCD to occur in high momentum transfer quasielastic nuclear reactions. For specific reactions involving nucleons, the initial and final state interactions are expected to be dominated by exchanges of pions. We argue that these interactions are also suppressed in high momentum transfer nuclear quasielastic reactions; this is ``chiral transparency". We show that studies of the $e ^3He \to e'Δ^{++} nn$ reaction could reveal the influence of chiral transparency.

description: A young, nearby compact aggregate of X-ray emitting pre-main sequence stars was recently discovered in the vicinity of eta Cha (B8V). In this paper, we further investigate this cluster: its membership, its environs and origins. ROSAT HRI X-ray data for the cluster's T Tauri stars show high levels of magnetic activity and variability. The cluster has an anomalous X-ray luminosity function compared to other young clusters, deficient in stars with low, but detectable X-ray luminosities. This suggests that many low-mass members have escaped the surveyed core region. Photographic photometry from the USNO-A2.0 catalog indicates that additional, X-ray-quiet members exist in the cluster core region. The components of the eclipsing binary RS Cha, previously modeled in the literature as post-MS with discordant ages, are shown to be consistent with being coeval pre-MS stars. We compute the Galactic motion of the cluster from Hipparcos data, and compare it to other young stars and associations in the fourth Galactic quadrant. The kinematic study shows that the eta Cha cluster, the TW Hya association, and a new group near epsilon Cha, probably originated near the giant molecular cloud complex that formed the two oldest subgroups of the Sco-Cen OB association roughly 10-15 Myr ago. Their dispersal is consistent with the velocity dispersions seen in giant molecular clouds. A large H I filament and dust lane located near eta Cha has been identified as part of a superbubble formed by Sco-Cen OB winds and supernova remnants. The passage of the superbubble may have terminated star-formation in the eta Cha cluster and dispersed its natal molecular gas.

description: Type Ia supernovae (SN Ia) are generally believed to be the result of the thermonuclear disruption of Chandrasekhar-mass carbon-oxygen white dwarfs, mainly because such thermonuclear explosions can account for the right amount of Ni-56, which is needed to explain the light curves and the late-time spectra, and the abundances of intermediate-mass nuclei which dominate the spectra near maximum light. Because of their enormous brightness and apparent homogeneity SN Ia have become an important tool to measure cosmological parameters. In this article the present understanding of the physics of thermonuclear explosions is reviewed. In particular, we focus our attention on subsonic (``deflagration'') fronts, i.e. we investigate fronts propagating by heat diffusion and convection rather than by compression. Models based upon this mode of nuclear burning have been applied very successfully to the SN Ia problem, and are able to reproduce many of their observed features remarkably well. However, the models also indicate that SN Ia may differ considerably from each other, which is of importance if they are to be used as standard candles.

description: The READ Scale (Reference Effort Assessment Data) is a six-point scale tool for recording qualitative statistics by placing an emphasis on recording effort, knowledge, skills, and teaching utilized by staff during a reference transaction. Institutional research grants enabled the authors to conduct a national study of the READ Scale at 14 diverse academic libraries in spring of 2007 and test its viability as a tool for recording reference statistics. The study data were collected from 179 individuals and 24 service points with over 22,000 transactions analyzed. There was a 52% return rate of an online survey of participants, with over 80% of respondents indicating they would recommend or adopt the Scale for recording reference transactions. The authors suggest that the READ Scale has the potential to transform how reference statistics are gathered, interpreted, and valued. This paper presents the findings of a nationwide study testing the Scale in spring 2007 and suggests practical approaches for using READ Scale data.

description: The dependence of the proton-to-electron mass ratio, mu, on the local matter density was investigated using methanol emission in the dense dark cloud core L1498. Towards two different positions in L1498, five methanol transitions were detected and an extra line was tentatively detected at a lower confidence level in one of the positions. The observed centroid frequencies were then compared with their rest frame frequencies derived from least-squares fitting to a large data set. Systematic effects, as the underlying methanol hyperfine structure and the Doppler tracking of the telescope, were investigated and their effects were included in the total error budget. The comparison between the observations and the rest frame frequencies constrains potential mu variation at the level of Dmu/mu < 6 x 10^(-8), at a 3 sigma confidence level. For the dark cloud we determine a total CH3OH (A+E) beam averaged column density of 3-4 x 10^(12) cm(-2) (within roughly a factor of two), an E- to A-type methanol column density ratio of N(A-CH3OH)/N(E-CH3OH) = 1.00 +/- 0.15, a density of n(H2) = 3 x 10^5 cm^(-3) (again within a factor of two), and a kinetic temperature of Tkin = 6 +/- 1 K. In a kinetic model including the line intensities observed for the methanol lines, the n(H2) density is higher and the temperature is lower than that derived in previous studies based on different molecular species; the intensity of the 1_0 --> 1_-1 E line strength is not well reproduced.

description: We provide a simple explanation of complex magnetic patterns observed in ferromagnetic nanostructures. To this end we identify elementary topological defects in the field of magnetization: ordinary vortices in the bulk and vortices with half-integer winding numbers confined to the edge. Domain walls found in experiments and numerical simulations in strips and rings are composite objects containing two or more of the elementary defects.

On polynomial collocation for second kind integral equations with fixed singularities of Mellin type

description: We consider a polynomial collocation for the numerical solution of a second kind integral equation with an integral kernel of Mellin convolution type. Using a stability result by Junghanns and one of the authors, we prove that the error of the approximate solution is less than a logarithmic factor times the best approximation and, using the asymptotics of the solution, we derive the rates of convergence. Finally, we describe an algorithm to compute the stiffness matrix based on simple Gauss quadratures and an alternative algorithm based on a recursion in the spirit of Monegato and Palamara Orsi. All together an almost best approximation to the solution of the integral equation can be computed with O(n^2[log n]^2) resp. O(n^2) operations, where n is the dimension of the polynomial trial space.

description: Non-selfadjoint operators play an important role in the modeling of open quantum systems. We consider a one-dimensional Schroedinger-type operator with dissipative boundary conditions and dissipative delta potentials. An explicit description of the characteristic function, the minimal dilation and the generalized eigenfunctions of the dilation is given. The quantities of carrier and current densities are rigorously defined. Furthermore we will show that the current is not constant and that the variation of the current depend essentially on the chosen density matrix and imaginary parts of the delta potentials. This correspondence can be used to model a recombination-generation rate in the open quantum system.

description: Presence of long-term conditions have been linked to morbidity and premature mortality. Preventing and reducing modifiable risk factors of long-term conditions improve symptoms and quality of life as well as reduce the risk of complications and premature mortality in populations with long-term conditions. This thesis aims to identify populations with increased cardiometabolic risk and understand whether breathlessness could influence this risk, as well as identify a possible intervention for reducing cardiovascular risk. Cardiometabolic profiles of adult survivors of severe COVID-19 were compared with COVID naïve healthy controls to understand whether COVID-19 may be linked to an increased risk of cardiometabolic diseases. Cardiometabolic risk indicators were also compared between adults with exertional breathlessness and healthy controls as well as post-COVID participants with and without breathlessness. A systematic review was also conducted to explore the effect of aerobic exercise training on pulse wave velocity in adults with and without long-term conditions.
Adult survivors of severe COVID-19 had an increased cardiometabolic risk compared to the healthy group, however breathlessness was not associated with an increased risk in this cohort. There was no difference in cardiometabolic risk indicators between adults with and without exertional breathlessness, although this study had a small sample size due to the restrictions of the COVID-19 pandemic. The systematic review showed that aerobic exercise training significantly reduces pulse wave velocity in health and disease and that age was the inversely associated with this reduction.

description: We study mild solutions to a semilinear Cauchy problem related to a supercritical superprocess taking values in the finite measures on the unit interval, whose underlying motion is the Wright-Fisher diffusion. We establish a dichotomy in the long-time behavior of this superprocess. When a parameter related to the growth of the process is smaller than or equal to a certain critical value (in our case one), the mass in the interior of the unit interval dies out after a finite random time, while for larger values of the growth parameter, the mass in the interior explodes with positive probability as time tends to infinity. In the case of explosion, the mass in the interior grows exponentially and is approximately uniformly distributed over the unit interval. We apply these results to show that the semilinear Cauchy problem has precisely four fixed points when the growth parameter is small and five fixed points when the growth parameter is large, and determine their domains of attraction.

description: The joint research project „A Future for Refugees in Rural Regions of Germany” takes various per-spectives to look at whether and how the integration of refugees can be tied to rural develop-ment. The research is organized into various interacting sub-projects that analyse the integration of refugees in a total of 35 case study communities within eight rural case study counties. Sub-project 1 uses indicators to compare the framework conditions relevant for integration and ana-lyse their influence on integration efforts and successes. In this working paper, 20 indicators, di-vided into eight dimensions of integration, are introduced and analysed. The selection of the di-mensions of integration bases on the categories identified in the integration model by Ager and Strang (2008). The basis for the analyses are mainly data of the national and state statistical of-fices, the German Federal Agency for Cartography and Geodesy, and the Accessibility Model of the Thuenen Institute. For the comparative analysis mathematical averages, maximums, mini-mums and standard deviations of the single indicators are compared. In order to enable compre-hensive comparisons, a z-score is applied to the indicator values. A differentiated total picture results from the analysis, which makes especially clear the specific “strengths” and “weaknesses” of the communities and counties studied with regard to the integration relevant framework con-ditions. Interestingly, the analysis reveals that the indicator values are for the most part near the average. Overall the framework conditions relevant for integration are more homogeneous than was assumed due to the various social economic situations of the counties chosen for the case studies. In the next stage of the project, these results will be mirrored with the survey results from the other sub-projects in order to more precisely document and evaluate framework condi-tions and results relevant for the integration of refugees.
