Music Therapists' Use of Visual Supports for Individuals with Autism Spectrum Disorder
Creators: name: Chapman, Taylor Ruthann
Publisher: name: University of Kentucky Libraries
Year: 2018

description: Abstract:
Visual supports, which provide information presented in a visual format to enhance achievement toward specific goals, can be very helpful for individuals who have autism spectrum disorder (ASD). Music therapists often use visual supports in their practice; however, research exploring how they do so is limited. In the present study, the researcher used a mixed-methods research design to explore music therapists’ use of visual supports for individuals who have ASD. The researcher e-mailed a survey to board-certified music therapists who opted to receive e-mails from the Certification Board for Music Therapists (CBMT), 525 of whom completed the entire survey. Approximately 70% of participants reported using visual supports “always” or “very often.” Participants most frequently reported using pictures with written words and visual schedules. Visual supports are most often used by music therapists in children’s facilities/schools and to address communication skills when working with individuals who have ASD. Participants most frequently reported using visual supports to generally enhance the session/interventions, using them to provide routine, predictability, and clear expectations for individuals who have ASD. Resources and recommendations provided by participants are also summarized. Open-ended responses were coded into themes, and most participants recommended specific software or applications and encouraged others to use certain visual supports, such as visual schedules and “real” pictures. Future researchers should examine the effectiveness of visual supports when used in music therapy sessions for individuals who have ASD.

description: In anticipation of the VLT/SPHERE planet imager guaranteed time programs, we have conducted a preparatory survey of 86 stars between 2009 and 2013 in order to identify new faint comoving companions to ultimately carry out a comprehensive analysis of the occurence of giant planets and brown dwarf companions at wide (10-2000 AU) orbits around young, solar-type stars. We used NaCo at VLT to explore the occurrence rate of giant planets and brown dwarfs between typically 0.1 and 8''. Diffraction-limited observations in H-band combined with angular differential imaging enabled us to reach primary star-companion brightness ratios as small as 10-6 at 1.5''. 12 systems were resolved as new binaries, including the discovery of a new white dwarf companion to the star HD8049. Around 34 stars, at least one companion candidate was detected in the observed field of view. More than 400 faint sources were detected, 90% of them in 4 crowded fields. With the exception of HD8049B, we did not identify any new comoving companions. The survey also led to spatially resolved images of the thin debris disk around HD\,61005 that have been published earlier. Finally, considering the survey detection limits, we derive a preliminary upper limit on the frequency of giant planets for semi-major axes of [10,2000] AU: typically less than 15% between 100 and 500 AU, and less than 10% between 50 and 500 AU for exoplanets more massive than 5 MJup and 10 MJup respectively, considering a uniform input distribution and with a confidence level of 95%.

From Practice to Performance: The Importance of Ballet in Degas's Dancer Painting Process
Creators: name: Hill, Whitney LeeAnn
Publisher: name: University of Kentucky Libraries
Year: 2018

description: Abstract:
The context in which any artist creates an artwork is integral to understanding its significance, and one crucial aspect of context is how a work was created. When first looking at how Edgar Degas created his dancer paintings, his process seems simple- he watched the dancers and then painted what he saw. However, that is only a surface examination of a much more complicated system of observation, practice, repetition, mastery, and reproduction. This thesis investigates how Degas bridged the gap between observation and understanding of balletic technique; how deep his knowledge of balletic technique was; and if Degas did have a deep understanding of balletic technique, what process he utilized to gain that knowledge. It reconstructs the process Degas utilized to learn and then reproduce the repertoire of the Paris Opéra ballet by pairing visual analysis of specific works with my own knowledge of ballet technique as a dancer of twenty years. Ultimately, this study reveals that Degas learned how to dance classical ballet by mimicking the process ballerinas used to learn how to dance: first watching, then doing, and finally performing.

description: Photon quantization is implemented in the standard model extension (SME) using the Gupta-Bleuler method and BRST concepts. The quantization prescription applies to both the birefringent and non-birefringent CPT-even couplings. A curious incompatibility is found between the presence of the Lorentz-violating terms and the existence of a nontrivial conjugate momentum $Π^0$ yielding problems with covariant quantization procedure. Introduction of a mass regulator term can avoid the vanishing of $Π^0$ and allows for the implementation of a covariant quantization procedure. Field-theoretic calculations involving the SME photons can then be performed using the mass regulator, similar to the conventional procedure used in electrodynamics for infrared-divergence regulation.

description: WSNs are envisioned to consist of many small devices that can sense the environment and communicate the data as required. The most critical requirement for widespread sensor networks is power efficiency since battery replacement is not viable. Many protocols are proposed to minimize the power consumption by using complex algorithms. However, it is difficult to perform these complex methods since an individual sensor node in sensor networks does not have high computational capacity. On the other hand, many sensor nodes should transfer the data packet to the sink node that collects the required data. Therefore, the operations of the sensor nodes over the route are terminated. It is difficult to deliver the data packet to the sink node even if some sensor nodes are active. In this paper, an introduction of WSNs is presented with a deep insight into the power-aware routing protocol for sensor networks. The protocols considered are LEACH,VGA and PEGASIS. In addition, a comparison of these protocols is also presented.

description: The hydrogen Ly-α line has a dominant influence in photo-ionization processes in the unperturbed terrestrial ionospheric D region. In this paper, we present a procedure of calculating the rate of photo-ionization induced by Ly-α photons based on relaxation of electron density after intensive perturbations like those caused by solar X flares. This theory is applied to the ends of relaxation periods following three cases of solar X flares from May 5, 2010, February 18, 2011 and March 24, 2011. The necessary data on low ionospheric plasma parameters were collected by the very low frequency (VLF) radio-wave technics. The electron concentration is calculated from the amplitude and phase of the VLF signal emitted by the DHO transmitter in Germany and recorded by a receiver located in Serbia.

description: We show that "dry" active nematics, e.g. collections of shaken elongated granular particles, exhibit large-scale spatiotemporal chaos made of interacting dense, ordered, band-like structures in a parameter region including the linear onset of nematic order. These results are obtained from the study of the relatively simple and well-known (deterministic) hydrodynamic equations describing these systems in a dilute limit, and of a self-propelled particle Vicsek-like model for this class of active matter. In this last case, revisiting the status of the strong fluctuations and long-range correlations now considered as landmarks of orientationally-ordered active phases, we show that the giant number fluctuations observed in the chaotic phase are a trivial consequence of density segregation. However anomalous density fluctuations are present in the homogeneous quasi-ordered nematic phase and characterized by a non-trivial scaling exponent.

description: The eta-mesic nuclei in which the eta meson is bound with nucleus via strong interaction was postulated about 25 years ago, however till now no experiment confirmed empirically its existence. The discovery of this new kind of an exotic nuclear matter would be very important for better understanding of the eta meson structure and its interaction with nucleons. The search for eta-mesic helium is carried out with high statistic and high acceptance with the WASA-at-COSY detection setup and the Cooler Synchrotron COSY. The search is conducted via the measurement of the excitation function for the chosen decay channels of the 4He-eta system. Until now two reactions dd -> (4He-eta)bound ->3Heppi- and dd -> (4He-eta)bound ->3Henpi0 have been measured with the beam momentum varied continuously around the eta meson production threshold. This contribution includes description of recently published results of the WASA-at-COSY experiment as well as brief presentation of preliminary results from the analysis of new data sample with 20 times larger statistics.

description: We analyze spectropolarimetric data taken with the Hinode spacecraft in quiet solar regions at the disk center. Distorted redshifted Stokes $V$ profiles are found showing a characteristic evolution that always follows the same sequence of phases. We have studied the statistical properties of these events using spectropolarimetric data from Hinode/SP. We also examined the upper photosphere and the low chromosphere using Mg i b2 and Ca ii h data from Hinode. Finally, we have applied the SIRGAUSS inversion code to the polarimetric data in order to infer the atmospheric stratification of the physical parameters. We have also obtained these physical parameters taking into account dynamical terms in the equation of motion. The Stokes V profiles display a bump that evolves in four different time steps, and the total process lasts 108 seconds. The Stokes I shows a strongly bent red wing and the continuum signal exhibits a bright point inside an intergranular lane. This bright point is correlated with a strong redshift in the Mg i b2 line and a bright feature in Ca ii h images. The model obtained from the inversion of the Stokes profiles is hotter than the average quiet-Sun model, with a vertical magnetic field configuration and field strengths in the range of kG values. It also presents a LOS velocity stratification with a Gaussian perturbation whose center is moving to deeper layers with time. We have examined a particular type of event that can be described as a plasmoid of hot plasma that is moving downward from the top of the photosphere, placed over intergranular lanes and always related to strong magnetic field concentrations. We argue that the origin of this plasmoid could be a magnetic reconnection that is taking place in the chromosphere.

description: We study transient dynamics of hole carriers injected at a certain time into a Mott insulator with antiferromagnetic long range order. This is termed ``dynamical hole doping" as contrast with chemical hole doping. Theoretical framework for the transient carrier dynamics are presented based on the two dimensional $t-J$ model. Time dependences of the optical conductivity spectra as well as the one-particle excitation spectra are calculated based on the Keldysh Green's function formalism at zero temperature combined with the self-consistent Born approximation. At early stage after dynamical hole doping, the Drude component appears, and then incoherent components originating from hole-magnon scatterings start to grow. Fast oscillatory behavior due to coherent magnon, and slow relaxation dynamics are confirmed in the spectra. Time profiles are interpreted as that doped bare holes are dressed by magnon clouds, and are relaxed into spin polaron quasi-particle states. Characteristic relaxation times for Drude and incoherent peaks strongly depend on momentum of a dynamically doped hole, and the exchange constant. Implications to the recent pump-probe experiments are discussed.

description: Infrared Dark Clouds (IRDCs) are unique laboratories to study the initial conditions of high-mass star and star cluster formation. We present high-sensitivity and high-angular resolution IRAM PdBI observations of N2H+ (1-0) towards IRDC G035.39-00.33. It is found that G035.39-00.33 is a highly complex environment, consisting of several mildly supersonic filaments (sigma_NT/c_s ~1.5), separated in velocity by <1 km s^-1 . Where multiple spectral components are evident, moment analysis overestimates the non-thermal contribution to the line-width by a factor ~2. Large-scale velocity gradients evident in previous single-dish maps may be explained by the presence of substructure now evident in the interferometric maps. Whilst global velocity gradients are small (<0.7 km s^-1 pc^-1), there is evidence for dynamic processes on local scales (~1.5-2.5 km s^-1 pc^-1 ). Systematic trends in velocity gradient are observed towards several continuum peaks. This suggests that the kinematics are influenced by dense (and in some cases, starless) cores. These trends are interpreted as either infalling material, with accretion rates ~(7 \pm 4)x10^-5 M_sun yr^-1 , or expanding shells with momentum ~24 \pm 12 M_sun km s^-1 . These observations highlight the importance of high-sensitivity and high-spectral resolution data in disentangling the complex kinematic and physical structure of massive star forming regions.

description: In this paper we study the effects of constraints on the dynamics of an adaptive segregation model introduced by Bischi and Merlone (2011). The model is described by a two dimensional piecewise smooth dynamical system in discrete time. It models the dynamics of entry and exit of two populations into a system, whose members have a limited tolerance about the presence of individuals of the other group. The constraints are given by the upper limits for the number of individuals of a population that are allowed to enter the system. They represent possible exogenous controls imposed by an authority in order to regulate the system. Using analytical, geometric and numerical methods, we investigate the border collision bifurcations generated by these constraints assuming that the two groups have similar characteristics and have the same level of tolerance toward the members of the other group. We also discuss the policy implications of the constraints to avoid segregation.

description: We present EMERGEN-Bioinfo, the digital platform to collect, process, manage and divulgate viral sequences and non-sensitive metadata, developed in the context of EMERGEN, the French plan for COVID-19 genomic surveillance and research. The bioinformatics platform relies on different components to manage all the steps from raw sequence collection to deposition in international repositories. This includes: (1) specific storage spaces for each one of the 60 teams of the consortium; (2) a data lake gathering all sequences (raw, mapped, consensus genomes, aligned genomic and peptidic sequences); (3) system-level workflows to handle the data flow trough all the components of the platform; (4) a covid-19 specific domain of the national Galaxy server (covid19.usegalaxy.fr); (5) EMERGEN-DB, a database to store and manage non-sensitive metadata and genomic consensus sequences ; (6) data brokering services to facilitate metadata management and curation, submission to international repositories (GISAID and ENA) and follow-up of their acceptance status. The EMERGEN-Bioinfo platform is complemented by a high-security digital platform (EMERGEN-HDS) certified for Health Data Storage, which will enable researchers to pair EMERGEN data with patient data from different sources (national COVID-19 and healthcare databases). All the software resources developed for this projects will be accessible under an open license, and re-usable for other national projects (e.g. ABRomics multi-omics platform for surveillance and research on antimicrobial resistance) or international cooperation (e.g. sharing with partners of the European bioinformatics infrastructure ELIXIR).
The effect of including molecular opacities of variable composition on the evolution of intermediate-mass AGB stars

description: Calculations from stellar evolutionary models of low- and intermediate-mass asymptotic giant branch (AGB) stars provide predictions of elemental abundances and yields for comparison to observations. However, there are many uncertainties that reduce the accuracy of these predictions. One such uncertainty involves the treatment of low-temperature molecular opacities that account for the surface abundance variations of C, N, and O. A number of prior calculations of intermediate-mass AGB stellar models that incorporate both efficient third dredge-up and hot bottom burning include a molecular opacity treatment which does not consider the depletion of C and O due to hot bottom burning. Here we update the molecular opacity treatment and investigate the effect of this improvement on calculations of intermediate-mass AGB stellar models. We perform tests on two masses, 5 M$_{\odot}$ and 6 M$_{\odot}$, and two metallicities, $Z~=~0.001$ and $Z~=~0.02$, to quantify the variations between two opacity treatments. We find that several evolutionary properties (e.g. radius, $T_{\rm eff}$ and $T_{\rm bce}$) are dependent on the opacity treatment. Larger structural differences occur for the $Z~=~0.001$ models compared to the $Z~=~0.02$ models indicating that the opacity treatment has a more significant effect at lower metallicity. As a consequence of the structural changes, the predictions of isotopic yields are slightly affected with most isotopes experiencing changes up to 60 per cent for the $Z~=~0.001$ models and 20 per cent for the $Z~=~0.02$ models. Despite this moderate effect, we conclude that it is more fitting to use variable molecular opacities for models undergoing hot bottom burning.

description: We show that the explanation of Thomas-Wigner rotation (TWR) and Thomas precession (TP) in the framework of special theory of relativity (STR) contains a number of points of inconsistency, in particular, with respect to physical interpretation of the Einstein velocity composition law in successive space-time transformations. In addition, we show that the common interpretation of TP falls into conflict with the causality principle. In order to eliminate such a conflict, we suggest considering the velocity parameter, entering into expression for the frequency of TP, as being always related to a rotation-free Lorentz transformation. Such an assumption (which actually resolves any causal paradoxes with respect to TP), comes however to be in contradiction with the spirit of STR. The results obtained are discussed.

description: This paper contains results on geometric Routh reduction and it is a continuation of a previous paper where a new class of transformations is introduced between Lagrangian systems obtained after Routh reduction. In general, these reduced Lagrangian systems have magnetic force terms and are singular in the sense that the Lagrangian does not depend on some velocity components. The main purpose of this paper is to show that the Routh reduction process itself is entirely captured by the application of such a new transformation on the initial Lagrangian system with symmetry.

This algorithm has fast convergence and has lower computation intensity making it suitable for audio recovery problems. This paper focuses on restoring an audio signal by using VLSI architecture called AMP-M that implements AMP algorithm. This architecture employs MAC unit with fixed bit Wallace tree multiplier, FFT-MUX and various memory units (RAM) for audio restoration. VLSI and FPGA implementation results shows that reduced area, high throughput, low power is achieved making it suitable for real time audio recovery problems.

description: In the solar corona, magnetic reconnection usually takes place at the singular configuration of magnetic field, in particular near a magnetic null owing to its high susceptibility to perturbations. In this Letter, we report a rare X-shaped structure, encompassing a magnetic null, above a trans-equatorial quadrupole active region group that is well observed by the Atmospheric Imaging Assembly (AIA). The observations show that this X-shaped structure is visible in all AIA EUV passbands and stably exists for days. However, possibly induced by flare activities at the northern part of the quadrupole active region group, the X-shaped structure starts to destabilize and meanwhile a jet erupted near its center at 15:05 UT on 2013 October 7. Through the non-linear force-free field modeling, we identify a magnetic null, which is above the quadrupole polarities and well corresponds to the X-shaped structure. After the jet eruption, the temperature and emission measure of the plasma near the X-shaped structure rise from 2.3 MK and 1.2x10^27 cm-5 at 15:01 UT to 5.4 MK and 3.7x10^27 cm-5 at 15:36 UT, respectively, revealed by the differential emission measure analysis, indicating that magnetic reconnection most likely takes place there to heat the plasma. Moreover, the height of the null has an increase of 10 Mm, which is most likely due to the partial opening of the field lines near the fan surface that makes the null underneath rise to seek for a new equilibrium.

description: The quark-gluon plasma formed as a result of heavy-ion collisions is currently investigated actively both theoretically and experimentally. According to the holographic approach, forming a quark-gluon plasma in the four-dimensional world is associated with creating black holes in a five-dimensional anti-de Sitter space. The multiplicity of particles produced in heavy-ion collisions is then determined by the entropy of the five-dimensional black hole, which is estimated by the area of the trapped surface. To fit the experimental data for multiplicity Kiritsis and Taliotis have proposed to consider black holes formation in modified ${AdS}_5$ spaces with different $b$-factors. In this paper we consider the formation of black holes under collision of membranes in modified ${AdS}_5$ spaces with $b$-factors. Following the previous proposals we consider the power-law and exponential $b$-factors, as well as mixed types of $b$-factors. We study dynamics of the change of the trapped surface area depending on the energy for each investigated space. We find that the power-law and mixed factors fit better to the experimental date.

description: We report a detailed Raman scattering study of the lattice dynamics in detwinned single crystals of the underdoped high temperature superconductor YBa2Cu3O6+x (x=0.75, 0.6, 0.55 and 0.45). Whereas at room temperature the phonon spectra of these compounds are similar to that of optimally doped YBa2Cu3O6.99, additional Raman-active modes appear upon cooling below ~170-200 K in underdoped crystals. The temperature dependence of these new features indicates that they are associated with the incommensurate charge density wave state recently discovered using synchrotron x-ray scattering techniques on the same single crystals. Raman scattering has thus the potential to explore the evolution of this state under extreme conditions.

description: A wireless sensor network (WSN) has important applications such as remote environmental monitoring and target tracking. This has been enabled by the availability, particularly in recent years, of sensors that are smaller, cheaper, and intelligent. These sensors are equipped with wireless interfaces with which they can communicate with one another to form a network. The design of a WSN depends significantly on the application, and it must consider factors such as the environment, the applications design objectives, cost, hardware, and system constraints. The goal of survey is to present a comprehensive review of the recent literature in wireless sensor network. This paper reviews the major development and new research challenges in this area.

description: This work reports the results of an ongoing numerical investigation dealing with the post-buckling behaviour, strength and Direct Strength Method (DSM) design of cold-formed steel (CFS), simply supported lipped channel beams experiencing distortional-global (D-G) interaction under uniform bending at elevated temperatures. It extends the scope of previous studies, carried out at room temperature, by considering beams (i) exposed to fire conditions (i.e., temperatures up to 800 ºC), (ii) displaying various cross-section dimensions, lengths and yield stresses, and (iii) exhibiting two different support conditions, differing in the end cross-section warping/local displacement/rotation restraints (they are either fully free or fully prevented). The results presented and discussed consist of post-buckling equilibrium paths, failure moments and collapse modes, which are obtained through ABAQUS shell finite element geometrically and materially non-linear analyses. The constitutive model adopted to simulate the temperature dependence of the steel material properties is based on that prescribed by EC3-1.2 for CFS. The D-G interactive failure moment data gathered in this work are used to assess the merits of the available DSM-based design approaches – developed for room temperature and only modified to account for the elevated temperature effects. The findings reported, including a few design considerations, provide encouragement to extend the current research effort with the purpose of searching for an efficient (safe and reliable) DSM-based design approach to estimate the D-G interactive failure moments of CFS beams at elevated temperatures.

description: The subject of this work is the modification and specification of an approach to detail the estimation of soil crack network characteristics. The modification aims at accounting for the corrected soil crack volume based on the corrected shrinkage geometry factor compared to known estimates of crack volume and shrinkage geometry factor. The mode of the correction relies on recent results of the soil reference shrinkage curve. The main exposition follows the preliminary brief review of available approaches to dealing with the geometry of soil crack networks and gives a preliminary brief summary of the approach to be modified and specified. To validate and illustrate the modified approach the latter is used in the analysis of available data on soil cracking in a lysimeter.

description: The possible existence of two families of compact stars, neutron stars and quark stars, naturally leads to a scenario in which a conversion process between the two stellar objects occurs with a consequent release of energy of the order of $10^{53}$ erg. We discuss recent hydrodynamical simulations of the burning process and neutrino diffusion simulations of cooling of a newly formed strange star. We also briefly discuss this scenario in connection with recent measurements of masses and radii of compact stars.

description: Die therapeutische Beziehung in der logopädischen Therapie ist, im Gegensatz zur Psychotherapie, bislang wenig untersucht. Es wird jedoch angenommen, dass das Konstrukt der therapeutischen Beziehung auch in der Logopädie von großer Bedeutung ist. Um in der Forschung und im klinischen Setting Rückschlüsse auf die Beziehung zwischen Therapeut*in und Patient*in ziehen zu können, werden geeignete Messinstrumente benötigt. Die Strukturale Analyse Sozialen Verhaltens (SASB) nach L.S. Benjamin dient zur Untersuchung der therapeutischen Interaktion und könnte auch in der logopädischen Forschung von Relevanz sein. Ziel dieser Arbeit ist es, die Übertragbarkeit der SASB auf das logopädische Setting zu beurteilen und zu überprüfen, wie sich diese Erkenntnisse auf das aktuelle Verständnis der (sprach-)therapeutischen Beziehung auswirken. Zur Umsetzung dieses Vorhabens wurde, neben einer strukturierten Literaturrecherche, eine Therapiesequenz eines stotternden Erwachsenen mithilfe der SASB analysiert. Die Ergebnisse dieser Arbeit deuten darauf hin, dass die SASB in angepasster Form auch in der logopädischen Forschung anwendbar ist. Ein erweitertes, an die Logopädie angepasstes, SASB-Modell wird in der Diskussion vorgestellt. Weitere Belege für die Anwendung und Anpassung der SASB in der Logopädie werden jedoch benötigt, um einen Transfer gewährleisten zu können.

description: In contrast to the field of psychotherapy, the therapeutic relationship in speech and language therapy is much less explored. It is believed that the construct of the therapeutic relationship is of great importance in the speech and language therapy as well. To evaluate the relationship between therapist and patient in research and clinical settings, measuring instruments are needed. The Structural Analysis of Social Behavior (SASB) from L.S. Benjamin is used to examine interpersonal interaction and could be relevant in speech and language research. This bachelor thesis aims to assess the transfer of the SASB to the setting of stuttering therapy and to evaluate the current understanding of the therapeutic relationship in speech and language therapy. To achieve this goal a structured literature research was executed. Additionally, a therapy of a stuttering adult was analysed using the SASB. Overall, there is evidence that an adapted SASB-model is applicable in speech and language therapy. Therefore, an extended SASB-model is presented in the discussion. However, more evidence and modification is needed to guarantee a transfer of the SASB. Keywords: therapeutic relationship, Speech and language therapy, SASB, Stuttering
Three-level superadiabatic quantum driving

description: The superadiabatic quantum driving, producing a perfect adiabatic transfer on a given Hamitonian by introducing an additional Hamiltonian, is theoretically analysed for transfers within a three-level system. Our starting point is the stimulated Raman adiabatic passage, realized through different schemes of laser pulses. We determine the superadiabatic correction for each scheme. The fidelity, robustness and transfer time of all the superadiabatic transfer schemes are discussed. We derive that all superadiabatic corrections are based on a $π$- (or near-$π$)-area pulse coupling between the initial and final states. The benefits in the protocol robustness overcome the difficulties associated to the actual implementation of the three-level superadiabatic transfer.
