description: Nowadays, the guitar is one of the most popular musical instruments all over the world. We can find a great number of models with a wide range of acoustic quality, depending on the way the guitar has been built. The guitar luthiers need to know how to control certain acoustic attributes depending on the type of instrument they want to make. Currently, most luthiers check these acoustic features by analysing the vibration modes and trying to tune them to certain frequencies. To analyse these modes, one of the most used techniques is to analyse the spectrum of the impulsive response by recording a guitar tapped just below its bridge. Although the vibration modes are very important for the final sound of the guitar, there are many more elements that affect the different characteristics that compose the timbre. In this master thesis, developed in the context of the company MIIL–Musical Instruments Innovation Lab, we have created a computing tool named GIRAS-Guitar Impulse Response Analysis Software. This software allows us to record impulsive responses of guitars, using the technique explained above, and analyse them to obtain new acoustic parameters in addition to the vibration modes, with the aim that these can be used to define the timbre of the instrument. The acoustic parameters we have extracted from the impulsive response have been: the vibration modes, attack time, decay time, vibration sensitivity, centroid, low-to-high frequency ratio and MFCC. To verify if all these computations are related to any timbre feature of the guitar, a small experiment has been made using 5 classical guitars and 4 guitarists, where each of the guitarists had to evaluate the timbre of the guitars according to certain characteristics such as attack, sustain, intelligibility, warmness, balance, volume and dynamic range. After measuring these 5 guitars with our programme, the results are that there are some parameters such as the vibration modes, the attack time, the decay time and the low-to-high frequency ratio, which are clear about their influence on the timbre, and others in which a deeper research and an improvement of the methodology followed is needed to know if they can help to describe the timbre. The most important conclusion of this project is that we have created a software that makes much easier the research on the guitar timber.

description: We study the structure of neutron stars in scalar-tensor theories for the nonminimal coupling of the form $(1+κξϕ^{2})\cal R$. We solve the hydrostatic equilibrium equations for two different types of scalar field potentials and three different equations of state representative of different degrees of stiffness. We obtain the mass-radius relations of the configurations and determine the allowed ranges for the term $ξϕ^2$ at the center of the star and spatial infinity based on the measured maximum value of the mass for neutron stars and the recent constraints on the radius coming from gravitational wave observations. Thus we manage to limit the deviation of the model from general relativity. We examine the possible constraints on the parameters of the model and compare the obtained restrictions with the ones inferred from other cosmological probes that give the allowed ranges for the coupling constant only. In the case of the Higgs-like potential, we also find that the central value for the scalar field cannot be chosen arbitrarily but it depends on the vacuum expectation value of the field. Finally, we discuss the effect of the scalar field potential on the mass and the radius of the star by comparing the results obtained for the cases considered here.

description: We study the thermally activated oscillations, or capillary waves, of a neutral metal cluster within the liquid drop model. These deformations correspond to a surface roughness which we characterize by a single parameter $Δ$. We derive a simple analytic approximate expression determining $Δ$ as a function of temperature and cluster size. We then estimate the induced effects on shell structure by means of a periodic orbit analysis and compare with recent data for shell energy of sodium clusters in the size range $50 < N < 250$. A small surface roughness $Δ\simeq 0.6$ Å~ is seen to give a reasonable account of the decrease of amplitude of the shell structure observed in experiment. Moreover -- contrary to usual Jahn-Teller type of deformations -- roughness correctly reproduces the shape of the shell energy in the domain of sizes considered in experiment.

description: The version of supergravity formulated by Ogievetsky and Sokatchev is almost identical to the conventional $N=1$ theory, except that the cosmological constant $Λ$ appears as a dynamical variable which is constant only by virtue of the field equations. We consider the canonical quantisation of this theory, and show that the wave function evolves with respect to a dynamical variable which can be interpreted as a cosmological time parameter. The square of the modulus of the wave function obeys a set of simple conservation equations and can be interpreted as a probability density functional. The usual problems associated with time in quantum gravity are avoided.

description: Positive practice environments promote the health, safety and well-being of health workers by supporting professionalism, acknowledging performance and ensuring opportunities for professional growth. According to the International Collaborating Partners of the Positive Practice Environments Campaign, positive practice environments foster a motivated, productive and high-performing pool of workers who deliver high quality care. Research shows that achieving positive practice environments for health care professionals is problematic worldwide. In Tanzania, the capacity of human resources for health managers to implement deliberate and strategic action to plan for and effectively deploy health workers, as well as safeguard their practice environments, is severely diminished. The basic strategic human resources management (SHRM) components model was used to guide understanding of the relationship between people management practices and the practice environment. This dissertation examined the people management practices that have been implemented in Tanzania and their impact on the practice environment experienced by associate clinicians (ACs), nurses and midwives who deliver emergency obstetric care (EmOC). Interview and survey data obtained from frontline ACs, nurses and midwives and members of Council Health Management Teams (CHMTs) tasked with planning for and deploying health human resources offered provider and managerial perspectives of the practice environment within which EmOC is delivered in Tanzania. The eight people management practices specified in the basic SHRM components model were applied in varying extents across the 48 districts assessed. Partial implementation contributed to loss of motivation and undermined the performance of ACs, nurses and midwives who deliver the essential interventions constituting EmOC in Tanzania.

Chiral Anomaly Calculation in the Extended Coupled Rarita-Schwinger Mode

description: We recalculate the chiral anomaly in the Abelian gauge model in which a spin-$\frac{1}{2}$ field is directly coupled to a Rarita-Schwinger spin-$\frac{3}{2}$ field, using the extended theory in which there is an exact fermionic gauge invariance. Since the standard gauge fixing and ghost analysis applies to this theory, the ghost contribution to the chiral anomaly is $-1$ times the standard chiral anomaly for spin-$\frac{1}{2}$. Calculation of the fermion loop Feynman diagrams contributing to the coupled model anomaly gives a result of $6$ times the standard anomaly, so the total anomaly is $5$ times the standard anomaly. This agrees with the result obtained from the unextended model taking the ghost contribution there as $0$, corresponding to a non-propagating ghost arising from exponentiating the second class constraint determinant, together with the fermion loop anomaly contribution in the unextended model of $5$ times the standard anomaly.

Managing Multiple Demands in the Adult ESL Classroom: A Conversation Analytic Study of Teacher Practices

description: While much research on teaching has focused on what teachers know, less attention has been devoted to understanding what they actually do. This empirical absence can be felt in particular in the adult English as a Second Language (ESL) instructional context, despite the continued growth of the U.S. immigrant population. The current study addresses this gap by examining discursive practices employed by experienced teachers as they manage multiple demands in the adult ESL classroom. Data include over 25 hours of video-recordings and transcripts of interaction in four intact classes taught by four instructors at two sites: an academic ESL program, housed at a community college, and a community-based ESL program, housed at a school of education. Microanalysis of teacher-student interaction, conducted within the framework of (multimodal) conversation analysis, uncovered three teacher practices for managing multiple demands. The first, voicing the student perspective, entails the teacher verbalizing how students (may) perceive or experience a pedagogic topic or task; the topic/task is framed in a way that acknowledges its difficulty or problematizes students’ engagement with it. By employing this practice, teachers simultaneously affiliate with the (potential) student perspective while preparing students for explanations of challenging topics or recruiting their participation. The second practice, binding student contributions, entails marking connections, verbally and/or non-verbally, between one student contribution and teacher explanation or the contributions or identities of other students. Through binding, the teacher displays responsiveness to individual contributions while promoting the engagement of (other individuals in) the class. The third practice, resource splitting, entails the use of verbal and embodied resources to simultaneously pursue different courses of action within a single turn, or the use of different embodied resources to do so. By “splitting” semiotic resources, the teacher can accomplish two actions at the same time: align as a recipient and validate one contribution while managing turn-taking or pursuing topic/task shifts. By providing empirically-grounded and fine-grained descriptions of actual teacher practices, this study contributes to explicating how the complex work of teaching is accomplished. Findings bring specificity to the conversation on what constitutes skillful teaching and may benefit teacher educators and novice (ESL) teachers.

Hardy-type inequalities for the Carnot-Carathéodory distance in the Heisenberg group

description: In this paper we study various Hardy inequalities in the Heisenberg group $\mathbb H^n$, w.r.t. the Carnot-Carathéodory distance $δ$ from the origin. We firstly show that the optimal constant for the Hardy inequality is strictly smaller than $n^2 = (Q-2)^2/4$, where $Q$ is the homogenous dimension. Then, we prove that, independently of $n$, the Heisenberg group does not support a radial Hardy inequality, i.e., a Hardy inequality where the gradient term is replaced by its projection along $\nabla_{\mathbb H}δ$. This is in stark contrast with the Euclidean case, where the radial Hardy inequality is equivalent to the standard one, and has the same constant. Motivated by these results, we consider Hardy inequalities for non-radial directions, i.e., directions tangent to the Carnot-Carathéodory balls. In particular, we show that the associated constant is bounded on homogeneous cones $C_Σ$ with base $Σ\subset \mathbb S^{2n}$, even when $Σ$ degenerates to a point. This is a genuinely sub-Riemannian behavior, as such constant is well-known to explode for homogeneous cones in the Euclidean space.

Iron Graveslabs: A Sideline of the Early Iron Industry

Publisher: name: Archaeology Data Service
Year: 2021

description: Sussex Archaeological Collections, 125, 99-113
description: Iron graveslabs are a peculiarity of, but not unique to, the Weald. They are found in a score or so of churches there and commemorate ironmasters and their families, or substantial yeomen and merchants, rather than gentry. As these families became more affluent and pretentious they were buried inside churches rather than in churchyards, their social aspirations rose and their graveslabs became larger and finer, often incorporating armorial bearings. By the 18th century marble mural tablets, as used by the gentry, were preferred, though bodies were often deposited under existing 'iron plates'. Decoration on the slabs in the form of letters and heraldic devices was made by impressing letters or pattern moulds into the sand casting-bed before pouring in molten iron to cast the slab. The casting of graveslabs paralleled the making and use of firebacks, a better known by-product of the Wealden iron industry. That graveslabs were a minor sideline of the ironworks and not executed by specialists is indicated by various illiteracies such as reversed and inverted letters, split words and the failure to distinguish between words. Made over a period of two centuries, they are durable, but subject to the vicissitudes of the changing fortunes of church buildings. After the charcoal-based iron industry ended, iron continued to be used to the early 20th century for churchyeard memorials. The 100 iron graveslabs of the Weald provide a tangible and eloquent record of a past industrial age and of the affluence accruing to certain families from it.

description: This dissertation focuses on utilizing data-driven approaches to objectively measure variation in the quality of care across different hospitals, understand how physicians make dynamic admission and routing decisions for patients, and propose potential changes in practice to improve the quality of care and patient flow management. This analysis was performed in the context of Intensive Care Units (ICUs) and the Emergency Department (ED).
      In the first part, we assess variation in the overall quality of care provided by both urban and rural hospitals under the same integrated healthcare delivery system when augmenting administrative data with detailed patient severity scores from the electronic medical records (EMRs). Using a new template matching methodology for more objective comparison, we found that the use of granular EMR data significantly reduces the variation across hospitals in common patient severity-of-illness levels. Further, we found that hospital rankings on 30-day mortality and estimates of length-of-stay (LOS) are statistically different from rankings based on administrative data.
      In the second part, we study ICU admission decision-making dynamically throughout a patient’s stay in the general ward/the Transitional Care Unit (TCU). We first used an instrumental variable approach and modern multivariate matching methods to rigorously estimate the potential benefits and costs of transferring patients to the ICU based on a real-time risk score for deterioration. We then used the quantified impact to calibrate a comprehensive simulation model to evaluate system performances under various new ICU transfer policies. We show that proactively transferring the most severe patients to the ICU could reduce mortality rates and LOS without increasing ICU congestion and causing other adverse effects.
      In the third part, we focus on understanding how physicians make ICU admission decisions for patients in the ED. We first used two sets of reduced-form regressions to understand 1) what and how patient risk factors and system controls impact the admission decision from the ED; and 2) what are the potential benefits of admitting patients from the ED to the ICU. We then proposed a dynamic discrete choice structural model to estimate to what extent physicians account for the inter-temporal externalities when deciding to admit a specific patient to the ICU, to the ward or let him/her wait in the ED. Note that the structural model estimation is still an ongoing process and more investigation is required to fine tune the details. Therefore, we will not discuss the structural model estimation results in this chapter, but only present the modeling framework and key estimation strategy.

description: Changing-look quasars are a newly-discovered class of luminous active galactic nuclei that undergo rapid ($\lesssim$10 year) transitions between Type 1 and Type 1.9/2, with an associated change in their continuum emission. We characterize the host galaxies of four faded changing-look quasars using broadband optical imaging. We use \textit{gri} images obtained with the Gemini Multi Object Spectrograph (GMOS) on Gemini North to characterize the surface brightness profiles of the quasar hosts and search for [O III] $\lambda4959,\lambda5007$ emission from spatially extended regions, or voorwerpjes, with the goal of using them to examine past luminosity history. Although we do not detect, voorwerpjes surrounding the four quasar host galaxies, we take advantage of the dim nuclear emission to characterize the colors and morphologies of the host galaxies. Three of the four galaxies show morphological evidence of merger activity or tidal features in their residuals. The three galaxies which are not highly distorted are fit with a single Sérsic profile to characterize their overall surface brightness profiles. The single-Sérsic fits give intermediate Sérsic indices between the $n=1$ of disk galaxies and the $n=4$ of ellipticals. On a color-magnitude diagram, our changing-look quasar host galaxies reside in the blue cloud, with other AGN host galaxies and star-forming galaxies. On a color-Sérsic index diagram the changing-look quasar hosts reside with other AGN hosts in the "green valley". Our analysis suggests that the hosts of changing-look quasars are predominantly disrupted or merging galaxies that resemble AGN hosts, rather than inactive galaxies.

description: Photo Response Non-Uniformity (PRNU) is a camera imaging sensor imperfection which has earned a great interest for source device attribution of digital videos. A majority of recent researches about PRNU-based source device attribution for digital videos do not take into consideration the effects of video compression on the PRNU noise in video frames, but rather consider video frames as isolated images of equal importance. As a result, these methods perform poorly on re-compressed or low bit-rate videos. This paper proposes a novel method for PRNU fingerprint estimation from video frames taking into account the effects of video compression on the PRNU noise in these frames. With this method, we aim to determine whether two videos from unknown sources originate from the same device or not. Experimental results on a large set of videos show that the method we propose is more effective than existing frame-based methods that use either only I frames or all (I-B-P) frames, especially on YouTube videos.

description: Firms' operations management decisions are often complicated by various types of uncertainties, ranging from micro level customer behavior to macro level economic conditions. Operating in the presence of uncertainties and volatilities is a challenging task, one that requires careful mathematical analysis and tailored treatment based on the uncertainty's characteristics. In this thesis we provide three distinct studies on managing stochastic uncertainty in dynamic marketplaces. The first study considers agents' dynamic interactions in a large matching market. A pair needs to inspect for their compatibility in order to form a match. We study a type of market failure called 'information deadlock' that may arise when pairs are only willing to inspect their most preferred prevailing partner. Under information deadlock, a large fraction of agents wait in the market for long (if not forever) in spite of there being opportunities remaining in their consideration sets. Using advanced tools in statistical physics and random graph theory, we derive how the size of the deadlock is affected by the market's primitives. We also show that information deadlock is prevalent in a wide range of markets. Our second study tackles a service firm's problem of choosing between a safe service mode and a risky service mode when serving a customer who might probabilistically churn. One key behavioral feature of the customer that we consider is named recency bias --- his happiness with the firm (that crucially determines his churn risk at the time) depends more heavily on his more recent experience. We show, by solving a stochastic control problem, that the firm should be risk-averse when the customer is marginally satisfied and risk-seeking when the customer is marginally unsatisfied. The optimal sandwich policy can significantly outperform the naive myopic policy in terms of customer lifetime value. Our third study deals with a dual sourcing problem under fluctuating economic conditions. We model this via an underlying Markov modulated state-of-the-world which affects the two suppliers’ cost structures, capacity limits and demands. We develop two approaches to show how the optimal combined ordering strategy from the two suppliers, along with a salvaging policy, can be efficiently computed, and characterize the relatively simple structure of the optimal policies. Interestingly, we find that the firm can, by exploiting the dual sourcing options, benefit from increased environmental volatilities that affect the suppliers’ cost structures or capacity limits.

description: Some University historians indicate that the Targum was first published as an annual in 1867, but of this we have no extant evidence. In January 1869, the Targum as we now know it, made its appearance as a monthly paper that concerned itself with student “literary contributions” and college news as well as serving as a vehicle for bringing news to alumni and the general public. The newspaper, which originally was for sale, varied in frequency over the years as did its title (The Targum, Rutgers Targum, Rutgers Daily Targum, and Daily Targum). The newspaper has continuously been published since 1869 with the exception of 19 months during the second world war, between February 1944 and October 1945. The Targum was published by the students of Rutgers College, and later Rutgers University—New Brunswick represented through the years as the Targum Association, Rutgers Targum Association, and Rutgers College Targum. As a student organization, the Targum operated under the oversight of the dean of students and student government but in October 1980, the Targum became an independent college paper.

description: We present the synthesis and structural characterisation of a transition metal oxide hydride, LaSrCoO_3H_{0.7}, which adopts an unprecedented structure in which oxide chains are bridged by hydride anions to form a two- dimensional extended network. The metal centers are strongly coupled by their bonding with both oxide and hydride ligands to produce magnetic ordering up to at least 350 K. The synthetic route is sufficiently general to allow the prediction of a new class of transition metal-containing electronic and magnetic materials.

Managing Uncertainty During Organization Design Decision-Making Processes: The Moderating Effects of Different Types of Uncertainty
Creators: Mann, Alice
Publisher: name: Columbia University

Subjects: Organizational behavior

description: Uncertainty about one's job or work environment is a common and aversive experience that organizational members typically seek to reduce or manage. This study investigates whether different types of uncertainty - informational uncertainty (i.e., not having sufficient information to confidently form social judgments) and standing uncertainty (i.e., instability in one's perception of positive regard from relevant others) - are qualitatively distinct. The study also examines whether both types of uncertainty are heightened by ongoing organizational factors (i.e., organization role and tenure) as well as temporary factors (i.e., affiliation with a division undergoing redesign). Implementing fair processes and procedures may be an effective way for organizational leaders to help organizational members address their uncertainty. Uncertainty has been shown to moderate the "fair process effect," such that the positive effect of higher process fairness (i.e., procedural, informational, and interpersonal fairness) on organizational members' attitudes is stronger when uncertainty is higher. Specifically, people's uncertainty about their standing in an organization has been shown to moderate the "process-outcome interaction effect," such that the positive effect of the interaction between higher process fairness and lower outcome fairness on organizational members' attitudes is stronger when uncertainty is higher. This study investigates whether informational uncertainty, like standing uncertainty, moderates the fair process effect and the process-outcome interaction effect. Study hypotheses were tested through a longitudinal field research design that utilized web-based questionnaires involving responses from 500 students, faculty, and administrators of an urban university undergoing an organization redesign effort. Both ongoing and temporary organizational factors were found to significantly reduce rather than heighten uncertainty, which was the opposite of what was predicted. Higher informational and standing uncertainty were found to enhance the positive effect of process fairness on organizational members' attitudes as predicted. But lower informational and standing uncertainty were also found to enhance the positive effect of process fairness on organizational members' attitudes, which was the opposite of what was predicted. Lower informational uncertainty, but not standing uncertainty, was found to enhance the positive effect of higher process fairness and lower outcome favorability on organizational members' attitudes, which was the opposite of what was predicted.

description: This paper describes the process employed and the work undertaken to enable the surrender of the mine permit relating to the two tailings deposits at the abandoned Red Mountain Mine site near Rossland, BC. The first phase of the work undertaken was to provide urgent remedial work for protection of the environment, primarily through rehabilitation or replacement of surface water drainage systems. The second phase was to up-grade the water management systems to the appropriate level given their consequences of failure. The final phase of work is to ensure long term geotechnical stability of the facilities to the same level of risk. Establishment of a sustaining fund will facilitate long term monitoring and maintenance of the facilities.

description: Recently, Rastall gravity is undergoing a significant surge in popularity. We obtain a power-law total mass-density profile for the inner region (within several effective radius) of early-type galaxies (ETGs) from the space-time structures which are described by the static spherically-symmetric solutions of Rastall gravity under the assumption of perfect fluid matter. We find that in the inner region of ETGs, the Rastall dimensionless parameter $β=κλ$ determines the mass distribution. We then use 118 galaxy-galaxy strong gravitational lensing systems to constrain the Rastall dimensionless parameter $β$. We find that the mean value of $β$ for total 118 ETGs is $β=0.163\pm0.001$(68\% CL) with a minor intrinsic scatter of $δ=0.020\pm 0.001$. Our work observationally illustrates the physical meaning of the Rastall dimensionless parameter in galaxy scale. From the Newtonian approximation of Rastall gravity, we also find that an absolute isothermal mass distribution for ETGs is not allowed in the framework of Rastall gravity.

description: The purpose of this thesis is to understand the role of transparency in modern architecture.  Specifically, as it relates to our understanding of its interior and the implications of this relationship regarding managing its integrity over time.
Inconsistencies in the application of current preservation policies to modern architecture occur largely because the regulations were developed for these more closed, traditional architectures.  In that architectural expression, the separation between outside and inside occurs visually. The dissolution of concrete divisions between exterior and interior that occurred within modern architecture requires the thought process involved in preserving, renovating and re-using these structures to be reconfigured.  There is a direct link now between the interior and exterior from the public’s perspective.  The focus of this thesis will be on buildings which utilize transparency to reveal the interior, focusing on views from the outside-in.
I will look to rework the generalized questions of stewardship in modern architecture towards the use of transparency specifically.  The three main questions wanting to be answered in reference to transparency are as follows;
1. How is transparency used in this building?
2. Does the way transparency is used effect possible future reconfigurations of space?
3. What interior elements (if any), beyond the physical façade, augment the purpose and reading of transparency?
These questions are explored in a series of case studies. The case studies will provide background on the original intent of the building and then continue to explore the building’s contemporary history touching on effects of evolving programming and exploring implications of any physical alterations on the significance of transparency.  The lessons learned from these studies as well as identified commonalities will be used to make recommendations of needed expansion of preservation policy to properly preserve this archetype into the future.

description: Using the optical reference geometry approach, we have derived in the following, a general expression for the ellipticity of a slowly rotating fluid configuration using Newtonian force balance equation in the conformally projected absolute 3-space, in the realm of general relativity. Further with the help of Hartle-Thorne (H-T) metric for a slowly rotating compact object, we have evaluated the centrifugal force acting on a fluid element and also evaluated the ellipticity and found that the centrifugal reversal occurs at around $R/R_s \approx 1.45$, and the ellipticity maximum at around $R/R_s \approx 2.75$. The result has been compared with that of Chandrasekhar and Miller which was obtained in the full 4-spacetime formalism.

description: In this paper, we couple together the dust evolution code two-pop-py with the thermochemical disk modelling code ProDiMo. We create a series of thermochemical disk models that simulate the evolution of dust over time from 0.018 Myr to 10 Myr, including the radial drift, growth, and settling of dust grains. We examine the effects of this dust evolution on the mid-infrared gas emission, focussing on the mid-infrared spectral lines of C2H2, CO2, HCN, NH3, OH, and H2O that are readily observable with Spitzer and the upcoming E-ELT and JWST. The addition of dust evolution acts to increase line fluxes by reducing the population of small dust grains. We find that the spectral lines of all species except C2H2 respond strongly to dust evolution, with line fluxes increasing by more than an order of magnitude across the model series as the density of small dust grains decreases over time. The C2H2 line fluxes are extremely low due to a lack of abundance in the infrared line-emitting regions, despite C2H2 being commonly detected with Spitzer, suggesting that warm chemistry in the inner disk may need further investigation. Finally, we find that the CO2 flux densities increase more rapidly than the other species as the dust disk evolves. This suggests that the flux ratios of CO2 to other species may be lower in disks with less-evolved dust populations.
