Introduction: There is a lack of understanding as to how sensory loss and sensory deficits impact those with LLA. The purpose of this research is to determine the extent to which people with LLA can discriminate between surfaces underfoot, in order to better understand the relationship between people with LLA and their perception of the ground they are walking on. We developed a test to determine which qualities of surfaces may be easier to distinguish.

Methods: 10 unimpaired adults and 2 adults with LLA participated. Participants compared surfaces underfoot that consisted of ceramic, rough tile, gravel, sand, and sandpaper to span surface qualities of motility and roughness. With their vision obscured, participants were asked to take two steps onto two adjacent samples, with one sample underneath each foot. Each sample was compared against a ceramic control sample. Participants were asked to report if the samples were the “same” or “different”. Unimpaired adults completed trials with a standardized shoe and with the participant’s personal footwear. Discrimination scores were computed as the proportion of correct responses (% Correct) in total and by sample. For the unimpaired group, logistic regression analysis was used to obtain an odds ratio for correct discrimination, with pairwise comparison to detect any associations between independent variables (footwear, session number, sample, leading leg) and correct responses.

Results: All participants were able to complete the testing protocol. For unimpaired participants, only sample had a statistically significant association with participant accuracy (p<0.001). Sandpaper achieved the lowest scores (%Correct=15%, 95% CI=[11; 19]). Participants were the most accurate when one of the surfaces was gravel (%Correct=95.4%, SD=1.17 CI=[92.5; 97.2]). Results for the two participants with LLA differed. Both individuals scored lower in comparison to unimpaired individuals on rough tile (z= -1.8 and -2.4, respectively).

Discussion: The combination of “rough” and “motile” qualities (gravel) produced the highest response accuracy for both groups. While results for the participants with LLA were mixed, both demonstrated poorer scores with the rough tile sample. This suggests that people with LLA have a harder time detecting rough surfaces compared to motile surfaces, possibly due to an absence of cutaneous sensation from the prosthetic limb.

Conclusion: Our findings suggest that discrimination ability depends on surface quality. Individuals with LLA may be able to discriminate between surfaces, despite sensory deficits, but at lower accuracies compared to unimpaired individuals.

description: Motivated by an experimental report of iridate superlattices, we performed first-principle electronic structure calculations for SrIrO$_3$/SrTiO$_3$. Heterostructuring causes SrIrO$_3$ to become Sr$_2$IrO$_4$-like, and the system has the well-defined $j_{\rm eff}$=1/2 states near the Fermi level as well as canted antiferromagnetic order within the quasi-two-dimensional IrO$_2$ plane. In response to a larger tensile strain, the band gap is increased due to the resulting increase in bond length and the bandwidth reduction. The ground state magnetic properties are discussed in comparison to the metastable collinear antiferromagnetic state. Our work sheds new light for understanding the recent experimental results on the iridate heterostructures.

Purpose: To determine physical therapists’ barriers to implementation and subsequent maintenance of evidence-based practices (EBPs) for treating neck pain from the American Physical Therapy Association (APTA) neck pain Clinical Practice Guideline (CPG) over the course of six months.

Materials and Methods: Participating physical therapists were trained on the EBPs of treating neck pain through a live 90-minute webinar followed by a hands-on, in-person 90-minute session. Clinics were supplied with all necessary equipment and reference guides. Assessment of participant maintenance to neck pain EBPs included data collection from a baseline Knowledge Check survey prior to educational sessions, an Implementation survey at two months post educational sessions, and a Maintenance survey at six months post educational sessions.

Results: 75% of the participants stated that they maintained the use of the recommended EBP guidelines six months after the educational sessions. When participants were asked how often they used the EBPs taught six months previously, 25% responded with, “about half of the time,” 50% responded with, “most of the time,” and 25% responded with, “always.”

The most commonly reported barriers were a high patient caseload, perception that patient outcomes were not improving, availability of one-on-one time with patients, and too short of patient treatment sessions to be able to implement EBP-related interventions for neck pain effectively. Participants who stated they had a high self- efficacy were more likely to perform mobilizations and use the recommended EBP modalities.

description: We present a reliable double-folding (DF) model for $^{4}$He-nucleus scattering, using the Melbourne $g$-matrix nucleon-nucleon interaction that explains nucleon-nucleus scattering with no adjustable parameter. In the DF model, only the target density is taken as the local density in the Melbourne $g$-matrix. For $^{4}$He elastic scattering from $^{58}$Ni and $^{208}$Pb targets in a wide range of incident energies from 20~MeV/nucleon to 200~MeV/nucleon, the DF model with the target-density approximation (TDA) yields much better agreement with the experimental data than the usual DF model with the frozen-density approximation in which the sum of projectile and target densities is taken as the local density. We also discuss the relation between the DF model with the TDA and the conventional folding model in which the nucleon-nucleus potential is folded with the $^{4}$He density.

description: "
Background: Individuals with Down syndrome (DS), often experience a slower gait speed and decreased quality of gait. Different types of footwear have shown changes in gait in people without DS. The current study aimed to examine the differences between wearing commercially available supportive shoes, unsupportive shoes, and no footwear on gait quality and speed in people with DS.

Methods: In this repeated measures study, 20 adults with DS walked under three footwear conditions: supportive, unsupportive, and no footwear. Gait deviations were scored according to the Rancho Los Amigos Observational Gait Analysis (OGA) and gait speed was measured using the 10-Meter Walk Test.

Results: When gait was examined, the OGA results showed significant differences across all three conditions for overall major deviations (F=3.912, df=2, p=.029; p=0.026) and overall total deviations (F=3.896, df=2, p=.029; p=0.047) for left and right legs, respectively. Pairwise comparisons between conditions did not reach significance. There was a significant difference in gait speed (Greenhouse-Geisser adjusted F=8.974, p=0.004). Gait speed was significantly faster when participants wore supportive shoes compared to when they walked barefoot (8.9±2.0 vs. 10.0±2.3, p=0.002) and compared to when they wore unsupportive shoes (8.9±2.0 vs. 10.8±3.4, p=0.014)

Conclusion: Adults with Down syndrome who wore supportive shoes demonstrated better gait quality with fewer deviations compared to when they walked barefoot. Additionally, they had a faster gait speed when walking in supportive shoes compared to both walking in unsupportive shoes and barefoot.

description: Processing very large graphs like social networks, biological and chemical compounds is a challenging task. Distributed graph processing systems process the billion-scale graphs efficiently but incur overheads of efficient partitioning and distribution of the graph over a cluster of nodes. Distributed processing also requires cluster management and fault tolerance. In order to overcome these problems GraphChi was proposed recently. GraphChi significantly outperformed all the representative distributed processing frameworks. Still, we observe that GraphChi incurs some serious degradation in performance due to 1) high number of non-sequential I/Os for processing every chunk of graph; and 2) lack of true parallelism to process the graph. In this paper we propose a simple yet powerful engine BiShard Parallel Processor (BPP) to efficiently process billions-scale graphs on a single PC. We extend the storage structure proposed by GraphChi and introduce a new processing model called BiShard Parallel (BP). BP enables full CPU parallelism for processing the graph and significantly reduces the number of non-sequential I/Os required to process every chunk of the graph. Our experiments on real large graphs show that our solution significantly outperforms GraphChi.

description: Sub-parsec binary massive black holes (BBHs) are long anticipated to exist in many QSOs but remain observationally elusive. In this paper, we propose a novel method to probe sub-parsec BBHs through microlensing of lensed QSOs. If a QSO hosts a sub-parsec BBH in its center, it is expected that the BBH is surrounded by a circum-binary disk, each component of the BBH is surrounded by a small accretion disk, and a gap is opened by the secondary component in between the circum-binary disk and the two small disks. Assuming such a BBH structure, we generate mock microlensing light curves for some QSO systems that host BBHs with typical physical parameters. We show that microlensing light curves of a BBH QSO system at the infrared-optical-UV bands can be significantly different from those of corresponding QSO system with a single massive black hole (MBH), mainly because of the existence of the gap and the rotation of the BBH (and its associated small disks) around the center of mass. We estimate the half-light radii of the emission region at different wavelengths from mock light curves and find that the obtained half-light radius vs. wavelength relations of BBH QSO systems can be much flatter than those of single MBH QSO systems at a wavelength range determined by the BBH parameters, such as the total mass, mass ratio, separation, accretion rates, etc. The difference is primarily due to the existence of the gap. Such unique features on the light curves and half-light radius-wavelength relations of BBH QSO systems can be used to select and probe sub-parsec BBHs in a large number of lensed QSOs to be discovered by current and future surveys, including the Panoramic Survey Telescope and Rapid Response System (Pan-STARRS), the Large Synoptic Survey telescope (LSST) and Euclid.

description: What was the role of the family in individual reproductive decisions during state socialism? Can this knowledge help us to understand the persistence of universal marriage and early entrance into parenthood, the emergence of ‘abortion culture’ and the rapid fertility decline after the Second World War in Eastern Europe? Based on first-hand accounts of courtship and marriage, birth control and abortion, childbearing and chil- drearing, this dissertation examines the role of family and social relationships in personal reproductive decisions and strategies in Soviet Ukraine from around 1950 to 1975. In this light, we will see the crucial role that continuities in local family relationships played in personal responses to the Soviet policies emerging during the Cold War. This research offers new explanations that underlay the similarities and differences in the fertility trends in western and eastern Ukraine during the Soviet time and what policy implications these processes may have for the demographic developments today.

description: Synthesis of a series of layered iron arsenides Ca1-xRExFeAs2 (112) was attempted by heating at 1000 C under a high-pressure of 2 GPa. The 112 phase successfully forms with RE = La, Ce, Nd, Sm, Eu and Gd, while Tb, Dy and Ho substituted and RE free samples does not contain the 112 phase. The Ce, Nd, Sm, Eu and Gd doped Ca1-xRExFeAs2 are new compounds. All of them exhibit superconducting transition except for the Ce doped sample. The behaviour of the critical temperature, with the RE ionic radii have been investigated.

description: Context: The R CrA cloud hosts a handful of Class 0/I low-mass young stellar objects. The chemistry and physics at scales $>500$ AU in this cloud are dominated by the irradiation from the nearby Herbig Be star R CrA. The luminous large-scale emission makes it necessary to use high-resolution spectral imaging to study the chemistry and dynamics of the inner envelopes and discs of the protostars. Aims: We aim to better understand the structure of the inner regions of these protostars and, in particular, the interplay between the chemistry and the presence of discs. Methods: Using Atacama Large Millimeter/submillimeter Array (ALMA) high-resolution spectral imaging interferometry observations, we study the molecular line and dust continuum emission at submillimetre wavelengths. Results: We detect dust continuum emission from four circumstellar discs around Class 0/I objects within the R CrA cloud. Towards IRS7B we detect C$^{17}$O emission showing a rotation curve consistent with a Keplerian disc with a well-defined edge that gives a good estimate for the disc radius at 50 AU. We derive the central object mass to $2.3M_{\odot}$ and the disc mass to $0.024M_{\odot}$. The observations are also consistent with a model of material infalling under conservation of angular momentum; however, this model provides a worse fit to the data. We also report a likely detection of faint CH$_3$OH emission towards this point source, as well as more luminous CH$_3$OH emission in an outflow orthogonal to the major axis of the C$^{17}$O emission. Conclusions: The faint CH$_3$OH emission seen towards IRS7B can be explained by a flat density profile of the inner envelope caused by the disc with a radius $\lesssim50$ AU. We propose that the regions of the envelopes where complex organic molecules are present in Class 0/I young stellar objects can become quenched as the disc grows.

Subjects: K250 - Conservation of buildings

description: Greece is experiencing a prolonged economic crisis, which also exhibits social and cultural dimensions. One of the cultural dimensions is the dereliction of the industrial heritage sites and the lack of alternative planning approaches for their future exploitation. The study examines the challenges of regenerating an industrial heritage in Thessaloniki through the involvement of three types of communities (community of action, place and interest) in order to work as a catalyst for the city by considering the local creative industries as a possible future use. It does so by examining various aspects; what is the significance of the industrial heritage, what are the heritage regeneration processes employed so far along with their challenges, whether collaborative approaches are valid for such undertakings and what is the nature and the role of the creative industries in urban regeneration. As the socio-economic conditions prevalent in an area play a dominant role in forming relationships, it selects a case-study – the Allatini Mills, and an area of interest – Thessaloniki, Greece, in combination with an investigation of the creative industries active in the particular city by employing a multitude of qualitative methods. This allows for a qualitative analysis that generates empirical data to identify the existing challenges of the Allatini Mills and, based on them, promotes and supports the rescuing of a historic building from possible demolition or continuous dereliction. This thesis in overall sits within the field of urban regeneration and contributes in finding what the challenges of converting an industrial heritage site in Thessaloniki into an urban catalyst for the city are.

Purpose/Methods: This study examines the impact of the use of asynchronous virtual interviews (AVIs) in the admissions process of the Doctor of Physical Therapy (DPT) program at the University of Nevada, Las Vegas (UNLV). This research aims to examine racial and ethnic subgroup differences in AVI scores, evaluate the influence of AVIs on applicant scores in the admissions process, and assess the AVI inter-rater reliability among faculty evaluators using data from the 2019-2022 admissions cycles.

Results: Significant differences were found in AVI scores among racial and ethnic groups, with Black applicants scoring highest and Asian applicants scoring lowest. Additionally, inclusion of AVIs had a significant impact on pre-interview and final applicant scores. Black applicants were the only group that saw an increase in overall score with inclusion of AVIs. Inter-rater reliability among faculty evaluators was poor, highlighting the need for further exploration of the process used by evaluators when grading AVIs. The study underscores the potential of AVIs to enhance diversity by providing underrepresented minorities with an opportunity to showcase additional skills and emphasizes the importance of addressing reliability issues to ensure fair evaluation of all applicants.

description: We present measurements of the electron temperature using gate defined quantum dots formed in a GaAs 2D electron gas in both direct transport and charge sensing mode. Decent agreement with the refrigerator temperature was observed over a broad range of temperatures down to 10 mK. Upon cooling nuclear demagnetization stages integrated into the sample wires below 1 mK, the device electron temperature saturates, remaining close to 10 mK. The extreme sensitivity of the thermometer to its environment as well as electronic noise complicates temperature measurements but could potentially provide further insight into the device characteristics. We discuss thermal coupling mechanisms, address possible reasons for the temperature saturation and delineate the prospects of further reducing the device electron temperature.

description: Pulsars, if existing and detectable in the immediate vicinity of the massive black hole (MBH) in the Galactic center (GC), may be used as a superb tool to probe both the environment and the metric of the central MBH. The recent discovery of a magnetized pulsar in the GC suggests that many more pulsars should exist near the MBH. In this paper, we estimate the number and the orbital distribution of pulsars in the vicinity of the MBH in the GC by assuming that the pulsar progenitors, similar to the GC S-stars, were captured to orbits tightly bound to the MBH through the tidal breakup of stellar binaries. We use the current observations on both the GC S-stars and the hypervelocity stars to calibrate the injection rate(s) of and the dynamical model(s) for the stellar binaries. By including the relaxation processes, supernova kicks, and gravitational wave radiation in our simulations, we estimate that ~97-190 (9-14) pulsars may presently orbit the central MBH with semimajor axes <=4000AU (<=1000AU), which is compatible with the current observational constraints on the number of the GC pulsars. The semimajor axis and the pericenter distance of the pulsar closest to the central MBH are probably in the range of ~120-460AU and ~2-230AU, respectively. Future telescopes, such as the SKA, may be able to detect a significant number of pulsars with semimajor axis smaller than a few thousand AU in the GC. Long-term monitoring of these pulsars would be helpful in constraining both the environment and the metric of the central MBH. Our preferred model also results in about ten hyperfast pulsars with velocity >~1500km/s moving away from the Milky Way.

description: Algorithms developed for scheduling applications on heterogeneous multiprocessor system focus on asingle objective such as execution time, cost or total data transmission time. However, if more than oneobjective (e.g. execution cost and time, which may be in conflict) are considered, then the problem becomes more challenging. This project is proposed to develop a multiobjective scheduling algorithm using Evolutionary techniques for scheduling a set of dependent tasks on available resources in a multiprocessor environment which will minimize the makespan and reliability cost. A Non-dominated sorting Genetic Algorithm-II procedure has been developed to get the pareto- optimal solutions. NSGA-II is a Elitist Evolutionary algorithm, and it takes the initial parental solution without any changes, in all iteration to eliminate the problem of loss of some pareto-optimal solutions.NSGA-II uses crowding distance concept to create a diversity of the solutions.

description: The China Dark Matter Experiment (CDEX) Collaboration will carry out a direct search for weakly interacting massive particles with germanium detectors. Liquid argon will be utilized as an anti-Compton and cooling material for the germanium detectors. A low-background and large-area photomultiplier tube (PMT) immersed in liquid argon will be used to read out the light signal from the argon. In this paper we carry out a careful evaluation on the performance of the PMT operating at both room and cryogenic temperatures. Based on the single photoelectron response model, the absolute gain and resolution of the PMT were measured. This has laid a foundation for PMT selection, calibration and signal analysis in the forthcoming CDEX experiments.

description: The creation and deployment of software development processes for new domains (such as wireless Internet services) is a challenging task due to the lack of knowledge about adequate engineering techniques and their effects. In addition, time-to-market pressure prevents applying long-lasting maturation of processes. Nevertheless, developing software of a predetermined quality in a predictable fashion can only be achieved with systematic development processes and the use of engineering principles. A descriptive approach promises to quickly create initial valuable process models and quantitative baselines that can be seen as starting points for continuous improvement activities. This paper describes the creation of software development processes for the development of wireless Internet services based on the observation of pilot projects that were performed at distributed development sites. Different techniques and tools such as descriptive process modeling, process documentation generation, goal-oriented measurement, and capturing qualitative experience were combined to gain process baselines. Results show that the observation-based approach helped to quickly come up with stable context-oriented development processes and get a better understanding of their effects with respect to quantitative and qualitative means.

description: In recent years sporting embodiment has attracted an increasing level of academicattention, including a burgeoning sociological corpus that draws influence from theexistential phenomenology of Maurice Merleau-Ponty. This combination ofphenomenology and sociology provides a powerful framework from which to examinesporting embodiment, and challenges many taken-for granted assumptions andpresuppositions regarding the often underexplored, undertheorized ‘mundane’ elementsof our sporting experience.Swimming is one physical culture where embodied experiences have been shown to becore elements of recreational or leisure swimming. Studies that examine the embodiedexperiences of competitive swimming, however, remain sparse, and tend to be limited tocritical sociological examinations of gendered relationships or training regimes, whichoften overlook the intense embodied experiences of training and competing. Utilisingethnographic methods of participant observation, conducted across three, five-weekimmersions, and 19 individual and three group interviews with senior performanceswimmers, this study develops a richer and deeper understanding of the competitiveswimming lifeworld and how a swimmer’s embodied experiences contributefundamentally to the construction of this lifeworld.The study aims were achieved by addressing five key themes generated from the data. Thefirst, ‘Becoming and Remaining’, focuses on the swimmers’ motivations for entering andremaining within the aquatic lifeworld. The second, ‘Doing Competitive Swimming’,presents the different ways in which the swimming body is central to the ‘doing’ ofcompetitive swimming. The third, ‘The Shifted Swimming Sensorium’ describes the varietyof sensory experiences that make up the swimmers’ sensory stock of knowledge. Thefourth, ‘Discomfort, Pain and Enduring’ examines the various painful experiences withinthe swimming lifeworld and how swimmers come to understand and endure these. Thefifth and final theme, ‘The Intersubjective and Intercorporeal Competitive SwimmingLifeworld’, challenges the notion of swimming as an individual sport highlighting the sharedand intercorporeal moments that emphasis the social nature of competitive swimming.

description: Purpose: Auditory verbal hallucinations (AVHs) are speech perceptions in the absence of a external stimulation. An influential theoretical account of AVHs in schizophrenia claims that a deficit in inner speech monitoring would cause the verbal thoughts of the patient to be perceived as external voices. The account is based on a predictive control model, in which verbal self-monitoring is implemented. The aim of this study was to examine lip muscle activity during AVHs in schizophrenia patients, in order to check whether inner speech occurred. Methods: Lip muscle activity was recorded during covert AVHs (without articulation) and rest. Surface electromyography (EMG) was used on eleven schizophrenia patients. Results: Our results show an increase in EMG activity in the orbicularis oris inferior muscle, during covert AVHs relative to rest. This increase is not due to general muscular tension since there was no increase of muscular activity in the forearm muscle. Conclusion: This evidence that AVHs might be self-generated inner speech is discussed in the framework of a predictive control model. Further work is needed to better describe how the inner speech monitoring dysfunction occurs and how inner speech is controlled and monitored. This will help better understanding how AVHs occur.

Background and Purpose: Chronic diabetes is a prevalent systemic disease that impairs physical functioning and often leads to increased risk of falls. Adopting an external focus of attention during motor skill practice has been shown to improve learning outcomes, however, it has not been examined in this population. We examined how attentional focus instructions (internal vs. external) affect balance performance and learning in older adults with and without diabetes.

Methods: Fifty-three older adults (27 with diabetes, 63.7±7.0 years) participated in the randomized, pre-post intervention study. The balance training involved 50 practice trials of a stabilometer task that was novel to all participants. Participants were randomized to receive either internal or external focus task instruction. Task performances were assessed at baseline, during training, and during a retention test. Primary outcomes were changes in balance task performance before and after training. The study protocol was approved by the UNLV Biomedical IRB, and participants gave written consent prior to data collection.

Results: Participants who received external focus instruction showed significantly greater increase in balance performance than individuals who received internal focus instruction (95% CI=[0.02; 4.05], p=0.048). While participants with diabetes exhibited poorer baseline task performance (p=0.02), both groups improved their relative task performance after training (95% CI=[5.25; 18.14], p<0.0001).

Discussion and Conclusions: Adopting an external focus of attention benefits performance during short-term training of a novel balance task in older adults with and without diabetes. Participants with diabetes were capable of improving task performance with practice at a relative rate similar to those without diabetes. This information may be useful for designing interventional strategies to improve physical function and mitigate fall risks in older adults with diabetes.

Three-body radiative heat transfer and Casimir-Lifshitz force out of thermal equilibrium for arbitrary bodies

description: We study the Casimir-Lifshitz force and the radiative heat transfer in a system consisting of three bodies held at three independent temperatures and immersed in a thermal environment, the whole system being in a stationary configuration out of thermal equilibrium. The theory we develop is valid for arbitrary bodies, i.e. for any set of temperatures, dielectric and geometrical properties, and describes each body by means of its scattering operators. For the three-body system we provide a closed-form unified expression of the radiative heat transfer and of the Casimir-Lifshitz force (both in and out of thermal equilibrium). This expression is thus first applied to the case of three planar parallel slabs. In this context we discuss the non-additivity of the force at thermal equilibrium, as well as the equilibrium temperature of the intermediate slab as a function of its position between two external slabs having different temperatures. Finally, we consider the force acting on an atom inside a planar cavity. We show that, differently from the equilibrium configuration, the absence of thermal equilibrium admits one or more positions of minima for the atomic potential. While the corresponding atomic potential depths are very small for typical ground state atoms, they may become particularly relevant for Rydberg atoms, becoming a promising tool to produce an atomic trap.

description: We compute one-loop renormalization group equations for non-singlet twist-four operators in QCD. The calculation heavily relies on the light-cone gauge formalism in the momentum fraction space that essentially rephrases the analysis of all two-to two and two-to-three transition kernels to purely algebraic manipulations both for non- and quasipartonic operators. This is the first brute force calculation of this sector available in the literature. Fourier transforming our findings to the coordinate space, we checked them against available results obtained within a conformal symmetry-based formalism that bypasses explicit diagrammatic calculations and confirmed agreement with the latter.

description: In universal extra-dimensional models a conserved Z_2 parity stabilizes the lightest Kaluza-Klein particle, a dark-matter candidate. Boundary-localized kinetic terms, in general, do not preserve this symmetry. We examine, in the presence of such terms, the single production of Kaluza-Klein excitations of the neutral electroweak gauge bosons and their decay to zero-mode fermion-antifermion pairs. We explore how experiments at the Large Hadron Collider constrain the boundary-localized kinetic terms for different compactification radii.

description: QuaLiKiz, a model based on a local gyrokinetic eigenvalue solver is expanded to include momentum flux modeling in addition to heat and particle fluxes. Essential for accurate momentum flux predictions, the parallel asymmetrization of the eigenfunctions is successfully recovered by an analytical fluid model. This is tested against self-consistent gyrokinetic calculations and allows for a correct prediction of the ExB shear impact on the saturated potential amplitude by means of a mixing length rule. Hence, the effect of the ExB shear is recovered on all the transport channels including the induced residual stress. Including these additions, QuaLiKiz remains ~10 000 faster than non-linear gyrokinetic codes allowing for comparisons with experiments without resorting to high performance computing. The example is given of momentum pinch calculations in NBI modulation experiments.
Three essays on the information-providing function of financial markets
Creators: name: Hu, Xingyi
Publisher: name: No Publisher Supplied
Year: 2024

description: This dissertation consists of three essays on the information-providing function of financial markets, with evidence from the VIX futures, CDS options, and stock markets. The first essay examines how the information from political events influences the VIX futures term structure. Focusing on the chance of policy changes, this study examines its impact on expected market uncertainty through the recent U.S. presidential elections. This study applies the VIX futures term structure and unveils both long-term and short-term impacts of the chance of policy changes: In the long term, the chance of policy changes elevates the convexity of the term structure, increasing concerns about future market volatility. In the short term, it changes the shape of the term structure around the event. Consistent findings are obtained from national polls, battleground states, and betting markets. The second essay examines the information-providing function of the index CDS (CDX) options market and uncovers characteristics that make the market a suitable venue for information-based trades: represented by its opacity, large trade size, and surged use in crises. More importantly, this study designs a new measure based on CDX options volume and demonstrates its predictive ability for the next-day S&P 500 index returns during the COVID-19 pandemic and the high inflation period in 2022. The predicting role reveals the information flow from institutional investors to public investors and has important implications for market efficiency. The third essay examines the impact of the Fed’s information on the stock market by unveiling incremental changes in market reactions across the Fed’s series of FOMC announcements. This study describes it as “the cumulative effect”, with strong initial impacts on market reactions moderated over the series of the Fed’s announcements. More importantly, this study highlights the significant role of the cumulative effect in stabilizing the initial strongly negative market reactions. The effectiveness of the cumulative effect is validated through analyzing intraday stock market reactions to the series of policy announcements and Press conferences during the COVID-19 pandemic and the 2022–2023 inflation. The exploration of the cumulative effect highlights the Fed’s significant role in shaping investors’ views and stabilizing the economy.
