Muting the masses: Effects of the spiral of silence in the college newsroom
Creators: name: Ritter, Blaire
Publisher: name: University of Nevada, Las Vegas
Year: 2013

description: This paper explores whether or not Elisabeth Noelle-Neumann's theory, the spiral of silence, is an accurate theoretical lens to examine the issues of censorship and conflict in the student broadcast newsroom. Using data collected from classroom observations and student interviews, levels of involuntary and voluntary censorship and editorial control were examined to see if they played a role in classroom dynamic and editorial decisions. Each instance was looked at to see if it fit five criteria; a threat of isolation by peers or community, a fear of this threat, a willingness to speak out by the majority, a quasi-statistical sense to gauge what is majority opinion, and a pluralistic ignorance by that incorrectly labeled a certain belief as the majority opinion, all of which are described in Noelle-Neumann's original research.
The literature reviewed examines the development of the spiral of silence in the classroom, reasons for omission, avoidance strategies, the role of academic freedom, and the effects on students who are not encouraged to participate. The existing research builds off Noelle-Neumann's hypothesis that a fear of isolation from one's peers is the main motivator behind student's lack of participation in class discussion. Students fear that they will be ridiculed by their classmates for either speaking out against the teacher or the majority opinion of the class. Their perceived minority opinion makes them second-guess themselves and feel inadequate amongst their peers. This increased insecurity causes them to withdraw from the class more and more, causing a downward spiral of participation. In addition to looking at research through the five criteria of the spiral of silence, social impact theory and Normative Social Influence were also used a supplemental material.
Overall, the ethnographic research and interview responses aim to provide a preliminary base for a study looking at the spiral of silence in the newsroom, as many qualities and effects of this theory transfer from the classroom to the professional newsroom environment. This research also provides a base for future educational studies that specifically look at improving classroom communication and participation.

description: Mobile Mapping is widely used for collecting large amounts of geo-referenced data. An important role plays sensor fusion, in order to evaluate multiple sensors such as laser scanner and cameras jointly. This requires to determine the relative orientation between sensors. Based on data of a RIEGL VMX-250 mobile mapping system equipped with two laser scanners, four optional cameras, and a highly precise GNSS/IMU system, we propose an approach to improve camera orientations. A manually determined orientation is used as an initial approximation for matching a large number of points in optical images and the corresponding projected scan images. The search space of the point correspondences is reduced to skylines found in both the optical as well as the scan image. The skyline determination is based on alpha shapes, the actual matching is done via an adapted ICP algorithm. The approximate values of the relative orientation are used as starting values for an iterative resection process. Outliers are removed at several stages of the process. Our approach is fully automatic and improves the camera orientation significantly.

description: It is doubtful that any woman who has become pregnant and delivered a child did not experience some level of anxiety or frustration. It is also not likely that these women did not have anything else occurring simultaneously in their lives, such as work, social, and family commitments. Pregnancy and the expectancy of bringing a new life into the world inherently carry a certain amount of stress and uncertainty. Finding oneself in this situation has an incredible impact when a young woman has perhaps not even fully developed herself, and is faced with the challenge of raising a child.

description: In this paper we present a novel approach for image orientation by combining relative rotations and tie points. First, we choose an initial image pair with enough correspondences and large triangulation angle, and we then iteratively add clusters of new images. The rotation of these newly added images is estimated from relative rotations by single rotation averaging. In the next step, a linear equation system is set up for each new image to solve the translation parameters with triangulated tie points which can be viewed in that new image, followed by a resection for refinement. Finally, we optimize the cluster of reconstructed images by local bundle adjustment. We show results of our approach on different benchmark datasets. Furthermore, we orient several larger datasets incl. unordered image datasets to demonstrate the robustness and performance of our approach.

description: Embryonic development is driven by spatial patterns of gene expression that determine the fate of each cell in the embryo. While gene expression is often highly erratic, embryonic development is usually exceedingly precise. In particular, gene expression boundaries are robust not only against intrinsic noise from gene expression and protein diffusion, but also against embryo-to-embryo variations in the morphogen gradients, which provide positional information to the differentiating cells. How development is robust against intra- and inter-embryonic variations is not understood. A common motif in the gene regulation networks that control embryonic development is mutual repression between pairs of genes. To assess the role of mutual repression in the robust formation of gene expression patterns, we have performed large-scale stochastic simulations of a minimal model of two mutually repressing gap genes in Drosophila, hunchback (hb) and knirps (kni). Our model includes not only mutual repression between hb and kni, but also the stochastic and cooperative activation of hb by the anterior morphogen Bicoid (Bcd) and of kni by the posterior morphogen Caudal (Cad), as well as the diffusion of Hb and Kni. Our analysis reveals that mutual repression can markedly increase the steepness and precision of the gap gene expression boundaries. In contrast to spatial averaging and cooperative gene activation, mutual repression thus allows for gene-expression boundaries that are both steep and precise. Moreover, mutual repression dramatically enhances their robustness against embryo-to-embryo variations in the morphogen levels. Finally, our simulations reveal that gap protein diffusion plays a critical role not only in reducing the width of gap gene expression boundaries via spatial averaging, but also in repairing patterning errors that could arise due to the bistability induced by mutual repression.

Meta-analysis of GWAS of over 16,000 individuals with autism spectrum disorder highlights a novel locus at 10q24.32 and a significant overlap with schizophrenia

description: Abstract Background Over the past decade genome-wide association studies (GWAS) have been applied to aid in the understanding of the biology of traits. The success of this approach is governed by the underlying effect sizes carried by the true risk variants and the corresponding statistical power to observe such effects given the study design and sample size under investigation. Previous ASD GWAS have identified genome-wide significant (GWS) risk loci; however, these studies were of only of low statistical power to identify GWS loci at the lower effect sizes (odds ratio (OR) <1.15). Methods We conducted a large-scale coordinated international collaboration to combine independent genotyping data to improve the statistical power and aid in robust discovery of GWS loci. This study uses genome-wide genotyping data from a discovery sample (7387 ASD cases and 8567 controls) followed by meta-analysis of summary statistics from two replication sets (7783 ASD cases and 11359 controls; and 1369 ASD cases and 137308 controls). Results We observe a GWS locus at 10q24.32 that overlaps several genes including PITX3, which encodes a transcription factor identified as playing a role in neuronal differentiation and CUEDC2 previously reported to be associated with social skills in an independent population cohort. We also observe overlap with regions previously implicated in schizophrenia which was further supported by a strong genetic correlation between these disorders (Rg = 0.23; P = 9 × 10−6). We further combined these Psychiatric Genomics Consortium (PGC) ASD GWAS data with the recent PGC schizophrenia GWAS to identify additional regions which may be important in a common neurodevelopmental phenotype and identified 12 novel GWS loci. These include loci previously implicated in ASD such as FOXP1 at 3p13, ATP2B2 at 3p25.3, and a ‘neurodevelopmental hub’ on chromosome 8p11.23. Conclusions This study is an important step in the ongoing endeavour to identify the loci which underpin the common variant signal in ASD. In addition to novel GWS loci, we have identified a significant genetic correlation with schizophrenia and association of ASD with several neurodevelopmental-related genes such as EXT1, ASTN2, MACROD2, and HDAC4.

description: The Standard Model prediction on the forward-backward asymmetry for $b\bar b$ production ($A^b_{FB}$) is well consistent with the data of LEP I at the Z-pole, but deviates from the data at $\sqrt s=89\; 93$ GeV which are slightly away from the pole. This deviation implies that there still is room for new physics. We calculate the $A^b_{FB}$ at vicinity of Z-pole in the Little Higgs Model as well as other measurable parameters such as $R_b$ and $R_c$, by which we may constrain the parameter space of the Little Higgs Model. This can be tested in the newly proposed tera-Z factory. With the fitted parameters we further make predictions on $A^b_{FB}$ and $A^t_{FB}$ for $t\bar t$ production at the ILC energy.

description: The precise classification and reconstruction of crossroads from multiple aerial images is a challenging problem in remote sensing. We apply the Conditional Random Fields (CRF) approach to this problem, a probabilistic model that can be used to consider context in classification. A simple appearance-based model is combined with a probabilistic model of the co-occurrence of class label at neighbouring image sites to distinguish classes that are relevant for scenes containing crossroads. The parameters of these models are learnt from training data. We use multiple overlap aerial images to derive a digital surface model (DSM) and a true orthophoto without moving cars. From the DSM and the orthophoto we derive feature vectors that are used in the classification. Within our framework we make use of a car detector based on support vector machines (SVM), which delivers car probability values. These values are used as additional feature to support the classification when the road surface is occluded by static cars. Our approach is evaluated on a dataset of airborne photos of an urban area by a comparison of the results to reference data. The evaluation is performed for images of different resolution. The method is shown to produce promising results when using the car probability values and higher image resolution.

description: The effect of the stellar flux on exoplanetary systems is becoming an increasingly important property as more planets are discovered in the Habitable Zone (HZ). The Kepler mission has recently uncovered circumbinary planets with relatively complex HZs due to the combined flux from the binary host stars. Here we derive HZ boundaries for circumbinary systems and show their dependence on the stellar masses, separation, and time while accounting for binary orbital motion and the orbit of the planet. We include stability regimes for planetary orbits in binary systems with respect to the HZ. These methods are applied to several of the known circumbinary planetary systems such as Kepler-16, 34, 35, and 47. We also quantitatively show the circumstances under which single-star approximations break down for HZ calculations.

description: Political parties are considered as important factors with regard to democratization and legitimacy of a political system. Post-communist ECE countries are characterized by researchers as manifesting weakly organized political parties, high voters’ volatility and ideological uncertainty. A number of studies indicate, on the contrary, that post-communist political systems are also featuring a stable institutionalized party system. It is usually argued that a high level of party system institutionalization is a necessary condition or a prerequisite for democratization. This paper aims to investigate the conditions of party polarization in those political systems in which there is a stable and institutionalized party system. Theoretically speaking it is argued that low effective number of parties, low degree of voters’ volatility and the stability among dominant parties constitute the main attributes of a highly institutionalized party system. The research question of the paper is: How to explain high party polarization given a relatively low effective number of parties in an institutionalized party system? The paper builds on the case study of Albania, which constitutes a deviant case contrary to the theoretical expectations. Contrary to a number of alternative theoretical explanations on the same issue, such as cultural explanations or those based on long-term causes as the nature of the dictatorial regime, this study present the following hypothesis: A change in the configuration of the social classes and ruling elites after 1992 together with the prevailing of a one dimensional dominant cleavage, opposite to a cross-cutting cleavage, in political competition brings about party polarization. The paper is based on the theoretical framework of Konrád and Szelényi (1979), and Eyal (2003) in order to identify the configuration of the postcommunist ruling elite as well as at the theoretical framework of (Dahl 1966) and (Casal Bèrtoa 2014) concerning the formation of cumulative one dimensional cleavage opposite to the multidimensional and cross-cutting cleavage and their different effects. The paper is a qualitative research combined with process-tracing method in order to identify the critical juncture, the pertinent actors, the mobilization of cleavages and the discursive articulation of the political conflict. Political manifestos, main political speeches and party newspapers constitute the data of the paper.
Ethanol Regulation of Synaptic GABAA  4 Receptors Is Prevented by Protein Kinase A Activation

description: Ethanol alters GABAA receptor trafficking and function through activation of protein kinases, and these changes may underlie ethanol dependence and withdrawal. In this study, we used subsynaptic fraction techniques and patch-clamp electrophysiology to investigate the biochemical and functional effects of protein kinase A (PKA) and protein kinase C (PKC) activation by ethanol on synaptic GABAAα4 receptors, a key target of ethanol-induced changes. Rat cerebral cortical neurons were grown for 18 days in vitro and exposed to ethanol and/or kinase modulators for 4 hours, a paradigm that recapitulates GABAergic changes found after chronic ethanol exposure in vivo. PKA activation by forskolin or rolipram during ethanol exposure prevented increases in P2 fraction α4 subunit abundance, whereas inhibiting PKA had no effect. Similarly, in the synaptic fraction, activation of PKA by rolipram in the presence of ethanol prevented the increase in synaptic α4 subunit abundance, whereas inhibiting PKA in the presence of ethanol was ineffective. Conversely, PKC inhibition in the presence of ethanol prevented the ethanol-induced increases in synaptic α4 subunit abundance. Finally, we found that either activating PKA or inhibiting PKC in the presence of ethanol prevented the ethanol-induced decrease in GABA miniature inhibitory postsynaptic current decay τ1, whereas inhibiting PKA had no effect. We conclude that PKA and PKC have opposing effects in the regulation of synaptic α4 receptors, with PKA activation negatively modulating, and PKC activation positively modulating, synaptic α4 subunit abundance and function. These results suggest potential targets for restoring normal GABAergic functioning in the treatment of alcohol use disorders.

description: What is the best way to pack objects into a container? This simple question, one that is relevant to everyday life, biology, and nanoscience, is easy to state but surprisingly difficult to answer. Here, we use computational methods to determine dense packings of a set of polyhedra inside a sphere, for up to 60 constituent packers. Our dense packings display a wide variety of symmetries and structures, and indicate that the presence of the spherical container suppresses packing effects due to polyhedral shape. Our results have implications for a range of biological phenomena and experimental applications, including blood clotting, cell aggregation, drug delivery, colloidal engineering, and the creation of metamaterials.

description: We present a new atmospheric extinction curve for Mauna Kea spanning 3200--9700 Å. It is the most comprehensive to date, being based on some 4285 standard star spectra obtained on 478 nights spread over a period of 7 years obtained by the Nearby SuperNova Factory using the SuperNova Integral Field Spectrograph. This mean curve and its dispersion can be used as an aid in calibrating spectroscopic or imaging data from Mauna Kea, and in estimating the calibration uncertainty associated with the use of a mean extinction curve. Our method for decomposing the extinction curve into physical components, and the ability to determine the chromatic portion of the extinction even on cloudy nights, is described and verified over the wide range of conditions sampled by our large dataset. We demonstrate good agreement with atmospheric science data obtain at nearby Mauna Loa Observatory, and with previously published measurements of the extinction above Mauna Kea.

description: We consider a two-dimensional electron gas in an inversion asymmetric layer and in the presence of spatially distributed magnetic impurities. We investigate the relationship between the geometrical properties of the wave-function and the system's spin dependent transport properties. A localization transition, arising when disorder is increased, is exhibited by the appearance of a fractal state with finite inverse participation ratio. Below the transition, interference effects modify the carrier's diffusion, as revealed by the dependence on the scattering time of the power law exponents characterizing the spreading of a wave packet. Above the transition, in the strong disorder regime, we find that the states are spin polarized and localized around the impurities. A significant enhancement of the spin current develops in this regime.

description: Topopographic mapping issues concern the area coverage at different scales and their age. The age of the map is determined by the system of updating. The United Nations (UNGGIM) have attempted to track the global map coverage at various scale ranges, which has greatly improved in recent decades. However the poor state of updating of base maps is still a global problem. In Saudi Arabia large scale mapping is carried out for all urban, suburban and rural areas by aerial surveys. Updating is carried out by remapping every 5 to 10 years. Due to the rapid urban development this is not satisfactory, but faster update methods are forseen by use of high resolution satellite imagery and the improvement of object oriented geodatabase structures, which will permit to utilize various survey technologies to update the photogrammetry established geodatabases. The longterm goal is to create an geodata infrastructure, which exists in Great Britain or Germany. © Authors 2018.

description: Inflammation, oxidative stress, and angiogenesis have been proposed to interact in age-related macular degeneration. It has been postulated that external stimuli that cause oxidative stress can increase production of vascular endothelial growth factor (VEGF) in retinal pigment epithelial (RPE) cells. In this study, we tested the hypothesis that the inflammatory cytokine, tumor necrosis factor alpha (TNF-α), contributed to choroidal neovascularization (CNV) by upregulating VEGF in RPE through intracellular reactive oxygen species (ROS)-dependent signaling and sought to understand the mechanisms involved.

description: I discuss here some well established experimental facts which have been shown to be generic of the pseudogap in underdoped cuprates. Some recent developments on Cellular Dynamic Mean Field Theories of the doped Hubbard model on a square lattice are nowadays allowing one to compute physical properties and k resolved single particle spectra. At high temperatures, recent results present qualitative features which perfectly fit the experimental observations done for more than two decades on the pseudogap in the cuprates. Most various broken symmetry states detected recently at lower temperatures than the pseudogap T*, certainly require more complicated modelling, and are not necessarily generic. I suggest that various perturbations due to the order (or disorder) of chemical dopants, which can hardly be avoided in actual materials, might drive the pseudogap electronic matter into specific ground states which exhibit interesting correlated electronic orders.

description: Dielectric and magnetic properties of Eu0.5Ba0.25Sr0.25TiO3 are investigated between 10 K and 300 K in the frequency range from 10 Hz to 100 THz. A peak in permittivity revealed near 130 K and observed ferroelectric hysteresis loops prove the ferroelectric order below thistemperature. The peak in permittivity is given mainly by softening of the lowest frequency polar phonon (soft mode revealed in THz and IR spectra) that demonstrates displacive character of the phase transition. Room-temperature X-ray diffraction analysis reveals cubic structure, but the IR reflectivity spectra give evidence of a lower crystal structure, presumably tetragonal I4/mcm with tilted oxygen octahedra as it has been observed in EuTiO3. The magnetic measurements show that the antiferromagnetic order occurs below 1.8 K. Eu0.5Ba0.25Sr0.25TiO3 has three times lower coercive field than Eu0.5Ba0.5TiO3, therefore we propose this system for measurements of electric dipole moment of electron.

description: We define a Maximum Likelihood (ML for short) estimator for the correlation function, ξ, that uses the same pair counting observables (D, R, DD, DR, RR) as the standard Landy and Szalay (1993, LS for short) estimator. The ML estimator outperforms the LS estimator in that it results in smaller measurement errors at any fixed random point density. Put another way, the ML estimator can reach the same precision as the LS estimator with a significantly smaller random point catalog. Moreover, these gains are achieved without significantly increasing the computational requirements for estimating ξ. We quantify the relative improvement of the ML estimator over the LS estimator, and discuss the regimes under which these improvements are most significant. We present a short guide on how to implement the ML estimator, and emphasize that the code alterations required to switch from a LS to a ML estimator are minimal.

description: With rapidly increasing deployment of surveillance cameras, the reliable methods for automatically analyzing the surveillance video and recognizing special events are demanded by different practical applications. This paper proposes a novel effective framework for security event analysis in surveillance videos. First, convolutional neural network (CNN) framework is used to detect objects of interest in the given videos. Second, the owners of the objects are recognized and monitored in real-time as well. If anyone moves any object, this person will be verified whether he/she is its owner. If not, this event will be further analyzed and distinguished between two different scenes: moving the object away or stealing it. To validate the proposed approach, a new video dataset consisting of various scenarios is constructed for more complex tasks. For comparison purpose, the experiments are also carried out on the benchmark databases related to the task on abandoned luggage detection. The experimental results show that the proposed approach outperforms the state-of-the-art methods and effective in recognizing complex security events. © 2017 Copernicus GmbH. All rights reserved.
Hardware Implementation Of Processor Allocator For Mesh Connected Chip Multiprocessors
Creators: name: Marri, Rana Sangram Reddy
Publisher: name: University of Nevada, Las Vegas
Year: 2012

description: The advancements in the semiconductor process technology and the current demand for highly parallel computing has led to the advent of Chip Multiprocessors (CMPs). CMP is the integration of two or more independent processor cores, which can read and execute program instructions, on to a single integrated circuit die. CMPs are the main computing platforms for research and development in parallel and high performance computing environments. They offer minimum inter-core communication latencies as the processor cores are present on a single chip.
The Operating System (OS) plays a key role in using a CMP effectively. The OS should support a multi-user environment in which the jobs are executed in parallel on different cores. This is handled by the processor management system of the OS. The Processor Management System consists of Job Scheduler (JS) and Processor Allocator (PA). The JS aligns the jobs in a queue in an order which is determined by the scheduling policy employed and thus specifying the job that is to be executed next. The PA deals with the selection of appropriate set of processors to execute the job scheduled by the job scheduler. Efficient design of a PA is crucial if one is to harness the full computational power of a CMP in large parallel computing systems.
This thesis deals with the processor allocation part of the processor management system. The motive of this thesis is the hardware implementation of a PA for a mesh-connected CMP. The PA is implemented and a synthesis report is presented which shows the amount of logic utilized. Many contiguous and non-contiguous allocation strategies have been proposed for mesh networks in the recent years. The Improvised First Fit algorithm is used to select the appropriate set of processors for executing an incoming job in this hardware implementation. This algorithm is a contiguous allocation algorithm and has complete sub-mesh recognition ability and uses a bit-map approach. The JS is assumed to be employing a First Come First Serve (FCFS) policy to schedule the jobs. This thesis also acts as the basis for the hardware implementation of PA that uses other allocation algorithms in different topologies.

description: In this work we compute the color fields in the mediator plane between a static quark and a static antiquark using quenched lattice QCD. In special, we see the effect of the quark-antiquark distance on the flux tube. To obtain this results an improved multihit technique is developed and an extend smearing technique is used. Then, we also discuss the flux-tubes in a system composed of two quarks and two antiquarks. The ground and first excited states fields are studied for different dispositions of the system.

2000 Year Moisture Source Record from a Central Nevada Speleothem
Creators: name: Pribyl, Paul
Publisher: name: University of Nevada, Las Vegas
Year: 2012

description: The goal of this study was to determine the moisture source of winter precipitation in the central Great Basin for the past 2000 years, and to elucidate the role of Pacific Ocean and North American climate variability modes in driving observed droughts of the region around the Medieval Climatic Anomaly (MCA, ~900-1300 CE). Here a high resolution (~2-4 year) precisely dated moisture source reconstruction is presented from the ?18O values of speleothem LC-1 collected from Leviathan Cave in central Nevada, which reveals significant ?18O variability. I attribute the ?18O variability to changes in winter-season moisture circulation over the past 2000 years, which were likely forced by the Pacific/North American (PNA) teleconnection and associated ocean-atmosphere phenomena. I suggest that lower (higher) ?18O values are indicative of increased (decreased) contribution northern-Pacific sourced moisture during winter months, and this was due to the presence of a more negative (positive) state of the PNA. It was found that during the MCA there was an increase in northern sourced precipitation resulting from the presence of a negative PNA state associated with droughts in the region.
Boosting Majorana zero modes

description: One-dimensional topological superconductors are known to host Majorana zero modes at domain walls terminating the topological phase. Their nonabelian nature allows for processing quantum information by braiding operations which are insensitive to local perturbations, making Majorana zero modes a promising platform for topological quantum computation. Motivated by the ultimate goal of executing quantum information processing on a finite timescale, we study domain walls moving at a constant velocity. We exploit an effective Lorentz invariance of the Hamiltonian to obtain an exact solution of the associated quasiparticle spectrum and wave functions for arbitrary velocities. Essential features of the solution have a natural interpretation in terms of the familiar relativistic effects of Lorentz contraction and time dilation. We find that the Majorana zero modes remain stable as long as the domain wall moves at subluminal velocities with respect to the effective speed of light of the system. However, the Majorana bound state dissolves into a continuous quasiparticle spectrum once the domain wall propagates at luminal or even superluminal velocities. This relativistic catastrophe implies that there is an upper limit for possible braiding frequencies even in a perfectly clean system with an arbitrarily large topological gap. We also exploit our exact solution to consider domain walls moving past static impurities present in the system.

A History and Analysis of the Works of Lynn Ahrens and Stephen Flaherty
Creators: name: Fisher, Matthew Paul
Publisher: name: University of Nevada, Las Vegas
Year: 2013

description: In the history of musical theatre there have been several celebrated composer-lyricist teams. For over thirty years in the modern era the talents of librettist-lyricist Lynn Ahrens and composer Stephen Flaherty have been heard on stage, in movies, and on television, both in collaboration with others and together. When they formed their professional partnership in 1983 they made a team that would give modern musical theatre its most unique pairing. Their work is not easy to identify. Their source materials vary greatly from show to show and the musical style is never the same. With their level of output, talents, and accolades it is curious that no one has written anything definitive and solely about them and their careers. They seem to be a footnote or passing fancy in most texts on musical theatre. Information about them is usually in the form of transcribed interviews and quotes for other stories or a short biography as a lead-in to an often too brief discussion of one of their shows. Lynn Ahrens and Stephen Flaherty have been one of the most compelling and vital librettist-composer teams writing for musical theatre in the latter part of the twentieth century and now into the twenty-first. It is the purpose of this thesis to give them and their work proper attention, and to demonstrate their validity and importance to the genre for the past three decades and into the future.
