Virtual investing communities

description: Due to the popularity of Web 2.0 and Social Media in the last decade, the percolation of user generated content (UGC) has rapidly increased. In the financial realm, this results in the emergence of virtual investing communities (VIC) to the investing public. There is an on-going debate among scholars and practitioners on whether such UGC contain valuable investing information or mainly noise.  I investigate two major studies in my dissertation. First I examine the relationship between peer influence and information quality in the context of individual characteristics in stock microblogging. Surprisingly, I discover that the set of individual characteristics that relate to peer influence is not synonymous with those that relate to high information quality. In relating to information quality, influentials who are frequently mentioned by peers due to their name value are likely to possess higher information quality while those who are better at diffusing information via retweets are likely to associate with lower information quality. Second I propose a study to explore predictability of stock microblog dimensions and features over stock price directional movements using data mining classification techniques. I find that author-ticker-day dimension produces the highest predictive accuracy inferring that this dimension is able to capture both relevant author and ticker information as compared to author-day and ticker-day. In addition to these two studies, I also explore two topics: network structure of co-tweeted tickers and sentiment annotation via crowdsourcing. I do this in order to understand and uncover new features as well as new outcome indicators with the objective of improving predictive accuracy of the classification or saliency of the explanatory models. My dissertation work extends the frontier in understanding the relationship between financial UGC, specifically stock microblogging with relevant phenomena as well as predictive outcomes.

description: The development of techniques to probe molecular transport and the dynamics of molecular interactions at interfaces is important for understanding and optimizing surface-based technologies including surface-enhanced spectroscopies, biological assays, sensors, catalysis, and chemical separations. In particular, the efficiency and resolution of separation via reversed-phase liquid chromatography is governed by the interaction of analytes with the solution/stationary phase interface. Most commonly, the stationary phase material consists of high surface area, micron-sized, mesoporous silica particles functionalized with n-alkane ligands. Understanding the timescales at which analyte molecules are transported through the interior of the particle, as well as adsorbed and desorbed from the particle surface, is of fundamental importance in the development of new, more efficient chromatographic materials. Probing chemical interactions at interfaces is difficult due to the selectivity needed to measure the small population of molecules at an interface versus bulk solution. Measuring interfacial chemical interactions within chromatographic particles has the added challenge that the majority of the surface area is contained within the particle making it difficult to measure interfacial processes directly. In this work, single-molecule spectroscopic techniques are used to measure the transport and adsorption/desorption kinetics of molecules at planar reversed-phase chromatographic interfaces and within reversed-phase chromatographic particles. Fluorescence imaging with single-molecule tracking is used to track the locations of fluorescent molecules during their retention within chromatographic particles. This yields information regarding their diffusion rates and their residence time within the particle. Statistical criteria based on the single-molecule localization resolution are also developed to characterize the population of strongly adsorbed molecules and their effect on intraparticle molecular residence times. Fluorescence imaging is also combined with fluorescence-correlation spectroscopy and used to measure fast interfacial transport and sorption kinetics at planar models of chromatographic interfaces. This technique has higher temporal resolution relative to imaging and is capable of measuring transport approaching free solution diffusion rates of small molecules. Finally, a comparison is made between interfacial transport rates and surface populations measured at planar chromatographic interfacial models versus within porous particles. It is found that n-alkyl modified planar interfaces are reasonable models for reversed-phase chromatographic particles with proper interpretation of measured parameters.

description: Biological systems evolve with minimum metabolic costs and use common components, and they represent guideposts toward a paradigm of manufacturing that is centered on minimum energy, local resources, and ecological integration. Here, a new method of metalworking that uses chitosan from the arthropod cuticle to aggregate colloidal suspensions of different metals into solid ultra-low-binder-content composites is demonstrated. These composites, which can contain more than 99.5% metal, simultaneously show bonding affinity for biological components and metallic characteristics, such as electrical conductivity. This approach stands in contrast with existing metalworking methods, taking place at ambient temperature and pressure, and being driven by water exchange. Furthermore, all the nonmetallic components involved are metabolized in large amounts in every ecosystem. Under these conditions, the composites' ability to be printed and cast into functional shapes with metallic characteristics is demonstrated. The affinity of chitometallic composites for other biological components also allows them to infuse metallic characteristics into other biomaterials. The findings and robust manufacturing examples go well beyond basic demonstrations and offer a generalizable new approach to metalworking. The potential for a paradigm shift toward biomaterials based on their unique characteristics and the principles of their manufacturing methods is highlighted.

description: Location information of people is valuable for many applications including logistics, healthcare, security and smart facilities. This dissertation focuses on localization of people in wireless sensor networks using radio frequency (RF) signals, speci cally received signal strength (RSS) measurements. A static sensor network can make RSS measurements of the signal from a transmitting badge that a person wears in order to locate the badge. We call this kind of localization method radio device localization. Since the human body causes RSS changes between pairwise sensor nodes of a static network, we can also use RSS measurements from pairwise nodes of a network to locate people, even if they are not carrying any radio device. We call this device-free localization (DFL). The  rst contribution of this dissertation is to radio device localization. The human body has a major e ect on the antenna gain pattern of the transmitting badge that the person is wearing, however, existing re

description: The familiar second derivative test for convexity, combined with resolvent calculus, is shown to yield a useful tool for the study of convex matrix-valued functions. We demonstrate the applicability of this approach on a number of theorems in this field. These include convexity principles which play an essential role in the Lieb-Ruskai proof of the strong subadditivity of quantum entropy.

Generic vanishing, pluri-canonical maps and volume of isolated sigularity
Creators: name: Zhang, Yuchen
Publisher: name: University of Utah
Year: 2014
Subjects: Pluri-canonical maps
Isolated singularity

description: In this thesis, we consider two different problems in birational geometry considered previously in the author's papers. The first problem concerns pluri-canonical maps in positive characteristic. We prove that for a smooth variety X of general type over an algebraically closed field k with positive characteristic, if X has maximal Albanese dimension and the Albanese map is separable, then |4KX| induces a birational map. The second problem is on the volume of isolated singularities over C. We give an equivalent definition of the local volume of an isolated singularity VolBdFF(X, 0) defined by Boucksom, de Fernex and Favre in the Q-Gorenstein case and we generalize it to the non-Q-Gorenstein case. We prove that there is a positive lower bound depending only on the dimension for the non-zero local volume of an isolated singularity if X is Gorenstein. We also give a non-Q-Gorenstein example with VolBdFF(X, 0) = 0, which does not allow a boundary   such that the pair (X,  ) is log canonical.
Economic Evaluation of 21-Gene Assay for Early Stage Breast Cancer Patients from the Perspective of the Chinese Health Care System
Creators: name: Zhou, Mi
Publisher: name: University of Utah

description: Traditional prognostic tools tended to overestimate the risk of cancer recurrence and recommend adjuvant chemotherapy plus tamoxifen for most of early stage breast cancer (ESBC) patients. 21-gene assay is validated as a better predictor that may support this decision-making process. Although the cost-effectiveness of 21-gene assay in developed countries is well researched, because of with huge differences in epidemiology, treatment, and healthcare system, these results cannot be generalized to China easily. This study aimed to evaluate the potential economic impact of incorporating 21-gene assay on Chinese ESBC patients. A cost-effectiveness analysis with a decision tree and Markov model was performed based on the validation studies of 21-gene assay and published literature. A hypothetical cohort of 10,000 Chinese female patients with LN-, ER+, HER2- ESBC at the age of 45 were chosen to undergo treatment guided by either 21-gene assay or NCCN guideline Chinese version. Costs were estimated under the Chinese health care system, from the health care provider's perspective, reported in 2008 Chinese Yuan (¥). Total costs, Quality-adjusted life years (QALYs), and incremental cost-effectiveness ratio (ICER) were estimated as outcome measures. Under base case analysis with the AC regimen as adjuvant chemotherapy, 21-gene assay saves ¥11 125 (US$1 628) with a higher QALY of 0.30 year per patient over 10 iv years. Replacing the chemotherapy with TC regimen results in an even larger cost saving of ¥13 285 (US$ 1 934) but less effective gain of 0.24 year. Although overall results were sensitive to the cost of 21-gene assay and NCCN guideline risk classification accuracy, they were still considered as highly cost-effective, in terms of the threshold defined by the World Health Organization (WHO). In conclusion, 21-gene assay-guided treatment is considered to have cost saving and quality of life gain compared with NCCN guideline-guided treatment from a Chinese health care system perspective. The results of this study should inform better clinical decision making in China.

description: The purpose of this study was to assess the influence of an acute bout of cardiovascular exercise on selective and sustained attention in preadolescent children. Secondary aims included determining if gender, baseline physical activity level, or intensity of exercise moderates the relationship between acute exercise and attentional processes. A within-subjects design was used to measure performance on the Conners' Continuous Performance Test (CPT II) following 20 min of sedentary activity (passively viewing a video) and 20 min of cardiovascular (CV) exercise. The CPT II was administered on two different testing days to 26 preadolescent children (age = 10.4 ± 1.16 years; 13 females). Participants wore ActiGraph GT1M accelerometers at the waist during the exercise session, which consisted of a 10-station aerobic circuit, designed to elicit and maintain a cardiovascular response. Testing began once heart rate returned to within 10% of preexercise levels. The Physical Activity Questionnaire for Children (PAQ-C) was administered as a baseline measure of physical activity levels. Average exercise intensities met national guidelines of spending greater than 50% exercise time at moderate to vigorous physical activity (MVPA). Results indicated that CV exercise had no adverse effects on selective or sustained attentional processes. Neither gender nor baseline physical activity level influenced this relationship. To meet daily recommended levels of MVPA, opportunities for CV exercise may be incorporated in the school day without adversely affecting student attention.

description: Occluded person re-identification (ReID) is a person retrieval task which aims at matching occluded person images with holistic ones. For addressing occluded ReID, part-based methods have been shown beneficial as they offer fine-grained information and are well suited to represent partially visible human bodies. However, training a part-based model is a challenging task for two reasons. Firstly, individual body part appearance is not as discriminative as global appearance (two distinct IDs might have the same local appearance), this means standard ReID training objectives using identity labels are not adapted to local feature learning. Secondly, ReID datasets are not provided with human topographical annotations. In this work, we propose BPBreID, a body part-based ReID model for solving the above issues. We first design two modules for predicting body part attention maps and producing body part-based features of the ReID target. We then propose GiLt, a novel training scheme for learning part-based representations that is robust to occlusions and non-discriminative local appearance. Extensive experiments on popular holistic and occluded datasets show the effectiveness of our proposed method, which outperforms state-of-the-art methods by 0.7% mAP and 5.6% rank-1 accuracy on the challenging Occluded-Duke dataset.

Essa riguarda soprattutto la fruizione, e poi la tutela, la conservazione, la valorizzazione e la circolazione. Lo stesso codice culturale aspira ad un modello unitario, ma esso può risultare inadatto ad una realtà differenziata, cosi come il modello dominicale risulta inadeguato, sia sul piano della congruità sia su quella della effettività, a risolvere problemi che in buona parte prescindono dalla titolarità dei beni.

description: Understanding the spatially and temporally variant phenological responses and cycles can greatly assist the administrative planning, policy making and management in grazing, planting, and ecosystem conservation. The linkages of analysis as a basis for management have received increasing attention in the context of climate change. This research focuses on analyzing phenological responses of vegetation as constrained and moderated by environmental factors, such as landscape and season, in the geographically diverse Upper Colorado River Basin (UCRB). Due to the geographic diversity of phenological forcing in the UCRB, several homogeneous phenological subregions (phenoregions) are delineated, and the phenological responses of vegetation are analyzed on a per phenoregion basis. A multivariate adaptive regression splines (MARS) approach is adopted to model and interpret the regionally and seasonally specific relationships between environmental drivers (temperature, precipitation and solar radiant energy) and vegetation abundance, indicated by a Vegetation Index (VI). Short-term predictions of vegetation abundance are made using the models. Taking into consideration the scale of the study area and the time-step of the models, 1 km 7-day interval eMODIS data and the 1 km NASA AMES Ecocast data are used to articulate the dependent and independent variables. The series of models are integrated into a prototype phenological Decision Support System (DSS) to provide predicted vegetation abundance over the growing season and the trends of climatic variables leading to potential grazing management strategies. The implementation of the DSS is a unique attempt to integrate phenological theory and GIS technology, the combination of which makes this DSS analytically-based, intuitive and more user-friendly.

description: Le fattispecie incriminatrici contenute nel c.d. codice dei beni culturali risultano disorganiche e frammentarie. Le condotte penalmente rilevanti sono individuati attraverso una tecnica di descrizione analitica, i reati risultano orientati a tutelare “funzioni amministrative” e non veri e propri “beni giuridici”, le pene previste sono spesso irrisorie e meramente simboliche.
Si tratta dunque di un sistema sanzionatorio complessivamente debole, caratterizzato da uno scarso coordinamento tra l’illecito penale e quello amministrativo. Emerge in tutta la sua urgenza la necessità di intervenire per via normativa, al fine di apprestare una tutela che risulti adeguata alla natura dei beni culturali come beni che appartengono all’intera umanità.

description: Recent breakthroughs in silicon photonics technology are enabling the integration of optical devices into silicon-based semiconductor processes. Photonics technology enables high-speed, high-bandwidth, and high-fidelity communications on the chip-scale-an important development in an increasingly communications-oriented semiconductor world. Significant developments in silicon photonic manufacturing and integration are also enabling investigations into applications beyond that of traditional telecom: sensing, filtering, signal processing, quantum technology-and even optical computing. In effect, we are now seeing a convergence of communications and computation, where the traditional roles of optics and microelectronics are becoming blurred. As the applications for opto-electronic integrated circuits (OEICs) are developed, and manufacturing capabilities expand, design support is necessary to fully exploit the potential of this optics technology. Such design support for moving beyond custom-design to automated synthesis and optimization is not well developed. Scalability requires abstractions, which in turn enables and requires the use of optimization algorithms and design methodology flows. Design automation represents an opportunity to take OEIC design to a larger scale, facilitating design-space exploration, and laying the foundation for current and future optical applications-thus fully realizing the potential of this technology. This dissertation proposes design automation for integrated optic system design. Using a buildingblock model for optical devices, we provide an EDA-inspired design flow and methodologies for optical design automation. Underlying these flows and methodologies are new supporting techniques in behavioral and physical synthesis, as well as device-resynthesis techniques for thermal-aware system integration. We also provide modeling for optical devices and determine optimization and constraint parameters that guide the automation techniques. Our techniques and methodologies are then applied to the design and optimization of optical circuits and devices. Experimental results are analyzed to evaluate their efficacy. We conclude with discussions on the contributions and limitations of the approaches in the context of optical design automation, and describe the tremendous opportunities for future research in design automation for integrated optics.

description: Nursing is both an art and a science. Empathy has been described as the 'art of nursing' (Carper, 1978). The science of nursing is evident in modern health care settings. A balance of the art and science of nursing should be encouraged. Empathy is the ability to put oneself in another's place and appreciate an experience from the other's point of view. Clinical empathy is acting upon this gained insight to plan and provide patient care. While nurses agree that empathy is important to nursing, to date, researchers have not studied the relationship between nurse empathy and patient satisfaction using qualitative methods. A case study approach was utilized to allow various methods of data collection and analysis. The study site was a magnet hospital using primary nursing since 1975. A purposive, nurse manager-nominated population of 17 primary nurses, and 12 nurse-nominated patients was obtained. Twelve nurse-patient pairs, and 12 key leaders were included in the study. Data collected included 41 interview transcripts from nurses, patients, and key nursing/hospital leaders. Nurses completed the Myself-toward-Other component of the Barrett-Lennard Relationship Inventory (BLRI) and the LaMonica Empathy Profile. Patients completed the Other-toward-Self component of the BLRI and a Patient Satisfaction Index. Both groups completed demographic questionnaires. Artifactual information was also subjected to content analysis. Content analysis of interview transcripts and artifactual information was ongoing during data collection and analysis. Findings indicated that nurse empathy positively influences patient satisfaction with care. Nurses and patients agreed the relationship that developed between the nurse and patient was very important. Nurses expressed a love of nursing and a joy in helping others. Nurses believed their empathic approach to patient care accounted for their satisfaction with nursing. Patients identified the most important nursing actions as 'being there,' and 'taking time to sit down and listen.' Nurses identified an ability to establish and maintain appropriate levels of involvement in nurse-patient relationships as important for effective nursing care. Implications for nursing administration, education, and practice are to foster empathic awareness in nurses and facilitate appropriate relationship development between nurses and patients.

description: Underground natural gas baseload storage facilities are a vital part of the world's natural gas infrastructure. These facilities allow Exploration & Production (E&P) and transmission pipeline companies to utilize natural gas assets year round while providing means for consistent gas supply throughout the year. The purpose of this thesis is to present a process in which a feasibility study can be conducted for a prospective baseload storage facility. This was accomplished by explaining 1) the theory of natural gas storage reservoir engineering; 2) geologic consideration for underground storage prospects; 3) design of a new underground baseload facility using decline curve analysis and hysteresis analysis; and 4) a detailed economic analysis of a storage prospect. A depleted natural gas reservoir was evaluated for its potential to become an underground baseload storage facility for natural gas. For this underground reservoir, it is estimated the Original Gas in Place (OGIP) was 59.4 Billion Cubic Feet (BCF) using hysteresis analysis. The cushion gas requirement was solved to be 50% of the OGIP, or 29.7 BCF. There is currently 7.4 BCF of native gas present in the reservoir. The required injection cushion gas requirement is estimated at 22.3 BCF. The maximum field deliverability was estimated to be 284.3 Thousand Cubic Feet per Day (MCF/D) at a reservoir pressure of 868.5 psia. The minimum field deliverability was estimated to be 83.8 MCF/D at a cushion gas pressure of 434.1 psia. Maximum and minimum deliverabilities assume 30 injection/withdrawal wells are present at 6 different well pads throughout the field. After analyzing three different economic scenarios for the prospective storage field it was determined this project is not economically feasible under current market conditions. Recommendations for future work include the operating company conducting a 3D seismic survey and re-evaluating the project using 3D reservoir simulation evaluating the possibilities of 1) using horizontal drilling to minimize number of wells, 2) simulate storage well performance if vertical wells are hydraulically fractured, and/or 3) simulate if the prospective storage facility can be pressurized over the original discovery pressure.

description: The main objective of this dissertation is to contribute to the understanding of nanomechanics in bilayer Si/Ge thin films and graphene. A set of multiscale modeling and simulations, using finite element analysis (FEA), material point method (MPM) and molecular dynamics (MD) method, have been performed to investigate structural, mechanical and growth properties of several different classes of low-dimensional nanostructures. By using FEA, we find that epitaxially grown Ge quantum dots on both sides of a Si nanoribbon adopt an anticorrelated configuration, in agreement with experiment. In addition, the Ge dots, acting as nanostressors, create a periodic strain field in the Si nanoribbon, which leads to the formation of a new class of single-element strain superlattice as predicted by first-principles electronic structure calculations performed by my collaborators. Also using FEA, we have investigated the morphological instability of strained thin film grown on curved substrates, revealing the physical origin of an antiphase morphology. Another accomplishment presented in this dissertation is the understanding of experimentally observed wiggling phenomenon in SiGe nanoribbons released on an SOI substrate. We build a continuum mechanics model to describe the buckling of the strained SiGe nanoribbon and its interaction with the substrate. Our theoretical model provides new insights to understanding the existing experimental results as well as useful guidance for future experiments, with broad implications in the fabrication of stretchable electronics by strain induced self-assembly. We also utilized solid mechanics analyses and MD simulations to study the maximum asymmetry in strain induced mechanical instability in graphene, a two-dimensional (2D) crystal with the thinnest possible thickness of only one atomic layer. The continuum mechanics theory shows perfect agreement with the atomistic MD simulation, even down to the scale of a few nanometers.

description: A quantum-light source that delivers photons with a high brightness and a high degree of entanglement is fundamental for the development of efficient entanglement-based quantum-key distribution systems. Among all possible candidates, epitaxial quantum dots are currently emerging as one of the brightest sources of highly entangled photons. However, the optimization of both brightness and entanglement currently requires different technologies that are difficult to combine in a scalable manner. In this work, we overcome this challenge by developing a novel device consisting of a quantum dot embedded in a circular Bragg resonator, in turn, integrated onto a micromachined piezoelectric actuator. The resonator engineers the light-matter interaction to empower extraction efficiencies up to 0.69(4). Simultaneously, the actuator manipulates strain fields that tune the quantum dot for the generation of entangled photons with corrected fidelities to a maximally entangled state up to 0.96(1). This hybrid technology has the potential to overcome the limitations of the key rates that plague QD-based entangled sources for entanglement-based quantum key distribution and entanglement-based quantum networks.

description: Canonical quantization of the photon -- a free massless vector field -- is considered in cosmological spacetimes in a two-parameter family of linear gauges that treat all the vector potential components on equal footing. The goal is setting up a framework for computing photon two-point functions appropriate for loop computations in realistic inflationary spacetimes. The quantization is implemented without relying on spacetime symmetries, but rather it is based on the classical canonical structure. Special attention is paid to the quantization of the canonical first-class constraint structure that is implemented as the condition on the physical states. This condition gives rise to subsidiary conditions that the photon two-point functions must satisfy. Some of the de Sitter space photon propagators from the literature are found not to satisfy these subsidiary conditions, bringing into question their consistency.
