description: Chapter 2 examines the role of sales (temporary price reductions) in the pricing of perishable products. When products can be stored, periodic sales are explained using inventories: the ability to store lets consumers wait for better prices. When consumers differ in their ability to wait, ﬁrms keep prices regularly high, using sales to target the low prices to the most patient consumers. This explanation is not reasonable for perishable goods, since they cannot be stored. Using a retail dataset, I show that nonetheless a cyclic pattern of sales is a major feature of how perishable products are priced. I explain this pattern using a dynamic model of loss leadership. I then test my model using grocery store data. Chapter 3 studies large contributions to crowdfunding projects and their impact on project success. I ﬁnd large contributions display a preference for being effective in helping projects succeed: they are often pivotal in the success of a project. These ﬁndings match predictions from a consumer choice explanation of how large contributions are made. I then examine the role large contributions play in project success. Using an instrumental variables approach, I show the ability of a project to attract large contributors is important: a project is 40-60% more likely to succeed if they can attract a large contributor. This inverts the logic of crowdfunding: the crowd may be important, but the success of many projects is driven by large contributors. Chapter 4 develops a method for determining whether a given observation is a sale or not in the context of a sequence of prices for a retail product. This classiﬁcation, based on a hidden Markov model framework has the advantage of using all the information available or classifying sales. I develop identiﬁcation requirements for this method, and illustrate its utility in directly testing questions of correlation for sales and other variables: allowing models to be evaluated without reduced-form analysis. I perform simulations, demonstrating the method’s accuracy method in classifying sales and understanding correlations. This chapter adds to the toolbox industrial economists have for studying sales, with advantages over existing methods of sales classiﬁcation.

description: With a state-of-the-art numerical method for solving the integral-differential equation of radiative transfer, we investigate the flux of the Ly$α$ photon $ν_0$ emergent from an optically thick halo containing a central light source. Our focus is on the time-dependent effects of the resonant scattering. We first show that the frequency distribution of photons in the halo are quickly approaching to a locally thermalized state around the resonant frequency, even when the mean intensity of the radiation is highly time-dependent. Since initial conditions are forgotten during the thermalization, some features of the flux, such as the two peak structure of its profile, actually are independent of the intrinsic width and time behavior of the central source, if the emergent photons are mainly from photons in the thermalized state. In this case, the difference $|ν_{\pm}-ν_0|$, where $ν_{\pm}$ are the frequencies of the two peaks of the flux, cannot be less than $2$ times of Doppler broadening. We then study the radiative transfer in the case where the light emitted from the central source is a flash. We calculate the light curves of the flux from the halo. It shows that the flux is still a flash. The time duration of the flash for the flux, however, is independent of the original time duration of the light source but depends on the optical depth of the halo. Therefore, the spatial transfer of resonant photons is a diffusion process, even though it is not a purely Brownian diffusion. This property enables an optically thick halo to trap and store thermalized photons around $ν_0$ for a long time after the cease of the central source emission. The photons trapped in the halo can yield delayed emission, of which the profile also shows typical two peak structure as that from locally thermalized photons. Possible applications of these results are addressed.

description: Detection of individual differences in personality traits of animals may prove beneficial for producers to help tailor management for individuals and to make selection decisions. Therefore, the objectives of this thesis were to

1) review and evaluate literature on relationships between individual cattle personality traits and feeding behavior, activity, and performance; and

2) evaluate and develop tests suitable for characterizing crossbred dairy-beef calves’ personalities and associations with behavioral patterns and performance.

The existing literature indicates that growth, intake, activity, and milk production measures from precision technologies have associations with cattle personality traits and behaviors identifiable through standardized tests. This indicates that stable differences among individuals may be identifiable in natural settings. Results from original research indicate that behavioral responses from personality tests (novel person and novel object/startle) of individually housed dairy-beef calves had associations with performance, activity, and feeding behavior. Fearful calves had negative associations with average daily gain (ADG) and dry matter intake (DMI), inactive calves had positive correlations with non-nutritive oral manipulation, and bold calves had no detected associations. Personality trait assessment of dairy-beef calves has potential to predict performance, activity, and feeding behavior on-farm that may help producers make timely decisions fit for their production system.

description: The aim of this paper is to review the classical limit of Quantum Mechanics and to precise the well known threat of chaos (and fundamental graininess)to the correspondence principle. We will introduce a formalism for this classical limit that allows us to find the surfaces defined by the constants of the motion in phase space. Then in the integrable case we will find the classical trajectories, and in the non-integrable one the fact that regular initial cells become "amoeboid-like". This deformations and their consequences can be considered as a threat to the correspondence principle unless we take into account the characteristic timescales of quantum chaos. Essentially we present an analysis of the problem similar to the one of Omnès [10,11], but with a simpler mathematical structure.

Publisher: name: Universität Regensburg
Year: 1998
Subjects: subject: 530 Physik

description: Force sensors are key elements of atomic force microscopes and surface profilometers. Sensors with an integrated deflection meter are particularly desirable. Here, quartz tuning forks as used in watches are utilized as force sensors. A novel technique is employed which simplifies the interpretation of the data and increases the imaging speed by at least one order of magnitude compared to previous implementations. The variation of the imaging signal with distance fits well to a Hertzian contact model. Images of compact discs and calibration gratings, which have been obtained with scanning speeds up to 230 μm/s, are presented.

description: A simple, rapid, and robust RP-HPLC method have been developed and validated to measure Esomeprazole and Itopride at wavelength (260 nm). A isocratic elution of samples performed on Symmetry C18 (4.6 mm × 250 mm particle size 5 μm) column with mobile phase consisting Acetonitrile: methanol (60:40%v/v) delivered at flow rate 0.9 ml/min. A good linear response was achieved over the range of 5-50μg/ml, respectively. The method was quantitatively evaluated in terms of system suitability test, linearity, precision, accuracy (recovery) and robustness as per standard guidelines. The method is simple, convenient and suitable for the analysis of Esomeprazole and Itopride in bulk drug.

description: The noise performance of the force sensor is crucial for optimizing the resolution in non-contact atomic force microscopy. Sensing forces in vacuum and low temperatures is even more demanding than at ambient conditions. Here we analyze the noise performance and the sensitivity of a force sensor based on a quartz tuning fork of which one of the prongs is fixed (qPlus sensor). The noise characteristic of the qPlus sensor, optical and piezoresistive detection schemes at room temperature are compared and the qPlus sensor is investigated at low temperatures. The frequency variation of quartz tuning forks as a function of temperature is experimentally determined for the temperature range from 4 to 300 K.

description: This paper presents a method for automated healing as part of off-line automated troubleshooting. The method combines statistical learning with constraint optimization. The automated healing aims at locally optimizing radio resource management (RRM) or system parameters of cells with poor performance in an iterative manner. The statistical learning processes the data using Logistic Regression (LR) to extract closed form (functional) relations between Key Performance Indicators (KPIs) and Radio Resource Management (RRM) parameters. These functional relations are then processed by an optimization engine which proposes new parameter values. The advantage of the proposed formulation is the small number of iterations required by the automated healing method to converge, making it suitable for off-line implementation. The proposed method is applied to heal an Inter-Cell Interference Coordination (ICIC) process in a 3G Long Term Evolution (LTE) network which is based on soft-frequency reuse scheme. Numerical simulations illustrate the benefits of the proposed approach.

description: The charge distribution in atoms with closed electron shells is spherically symmetric, whereas atoms with partially filled shells can form covalent bonds with pointed lobes of increased charge density. Covalent bonding in the bulk can also affect surface atoms, leading to four tiny humps spaced by less than 100 picometers in the charge density of adatoms on a (001) tungsten surface. We imaged these charge distributions by means of atomic force microscopy with the use of a light-atom probe (a graphite atom), which directly measured high-order force derivatives of its interaction with a tungsten tip. This process revealed features with a lateral distance of only 77 picometers.

description: Discharging a liquid from a nozzle at sufficient large velocity leads to a continuous jet that due to capillary forces breaks up into droplets. Here we investigate the formation of microdroplets from the breakup of micron-sized jets with ultra high-speed imaging. The diminutive size of the jet implies a fast breakup time scale $τ_\mathrm{c} = \sqrt{ρr^3 / γ}$ of the order of 100\,ns{}, and requires imaging at 14 million frames per second. We directly compare these experiments with a numerical lubrication approximation model that incorporates inertia, surface tension, and viscosity [Eggers and Dupont, J. Fluid Mech. 262, 205 (1994); Shi, Brenner, and Nagel, Science 265, 219 (1994)]. The lubrication model allows to efficiently explore the parameter space to investigate the effect of jet velocity and liquid viscosity on the formation of satellite droplets. In the phase diagram we identify regions where the formation of satellite droplets is suppressed. We compare the shape of the droplet at pinch-off between the lubrication approximation model and a boundary integral (BI) calculation, showing deviations at the final moment of the pinch-off. Inspite of this discrepancy, the results on pinch-off times and droplet and satellite droplet velocity obtained from the lubrication approximation agree with the high-speed imaging results.

description: Atomic force microscopy (AFM) is a mechanical profiling technique that allows to image surfaces with atomic resolution. Recent progress in reducing the noise of this technique has led to a resolution level where previously undetectable symmetries of the images of single atoms are observed. These symmetries are related to the nature of the interatomic forces. The Si(111)-(7 × 7) surface is studied by AFM with various tips and AFM images are simulated with chemical and electrostatic model forces. The calculation of images from the tip-sample forces is explained in detail and the implications of the imaging parameters are discussed. Because the structure of the Si(111)-(7 × 7) surface is known very well, the shape of the adatom images is used to determine the tip structure. The observability of atomic orbitals by AFM and scanning tunneling microscopy is discussed.

description: The short-time Fourier transform (STFT) is a time-frequency representation widely used in applications, for example in audio signal processing. Recently it has been shown that not only the amplitude, but also the phase of this representation can be successfully exploited for improved analysis and processing. In this paper we describe a rather peculiar pole phenomenon in the phase derivative, a recurring pattern that appears in a characteristic way in the neighborhood around any of the zeros of the STFT, a negative peak followed by a positive one. We describe this phenomenon numerically and provide a complete analytical explanation.

description: In Denmark, fine needle aspiration is the standardized tool for obtaining tissue samples from lymph nodes (LN) of the neck. However, because of a low specificity toward lymphomas, LNs suspicious for this disease are often surgically removed and examined. International studies have implied that a core needle biopsy (CNB) is sufficient for detecting lymphomas, thereby potentially avoiding surgery. However, all studies have been conducted retrospectively and the goal of this prospective study was to find the true sensitivity of CNB. Fifty-seven patients were enrolled in the study, one was excluded due to lack of CNB material. LNs suspected for lymphoma were surgically removed from the neck, whereafter a CNB was obtained from the removed LN. The CNB and the remaining part of the LN were sent to the Department of Pathology for further processing and the samples were blinded and examined by two pathologists separately. A consensus diagnosis was reached in cases with divergent diagnostic proposals. Sensitivity of the CNB method in comparison to whole tissue sections for lymphoma diagnosis was calculated. The CNB method gave the correct diagnosis in 66% of lymphoma cases, was inconclusive in 14% and gave an incorrect lymphoma subtype in 18%. In 2% the CNB wrongly resulted in a benign diagnosis. CNB was correct in all the non-lymphoma cases; thereby retaining a specificity of 100%. This prospective study found a sensitivity of 66% for diagnosing lymphoma with a CNB. As the CNB in this study was obtained under optimal conditions, unlike in clinical practice, we conclude that CNB cannot be recommended as a standard tool for diagnosing lymphomas.
‘If you had to write a short diversity statement about yourself, what would you say?’: using diversity statements and introductory stories to develop holistic understandings of participants’ intersectional identities

description: There is an increasing focus on collecting more diverse demographic data from research participants but standard methodological approaches still hinder such efforts. This paper addresses the need for methodological improvements by advocating for the inclusion of self-written diversity statements in demographic surveys as a form of epistemic justice. Using examples from a large qualitative research study, I demonstrate the depth and richness of data that can be obtained through self-written diversity statements. In particular, I highlight the benefits of combining open-ended demographic questions and self-written diversity statements into holistic introductory stories to help capture the complexity of participants’ intersectional identities. Therefore, I argue that using such an approach gives participants the agency to choose how they are represented in research.
Using risk ratios as a method of calculating substantial racial and ethnic disproportionality rates in school discipline

Publisher: name: University of British Columbia
Year: 2017

description: The discipline gap – a phenomenon by which students of colour (e.g., Black students) are disproportionately affected by school exclusionary discipline compared to their White peers – has been reliably documented for more than 50 years. Researchers have relied on different metrics, analysis methods, and data sources to measure the discipline gap. Regulators have proposed the standard use of risk ratios as a metric to measure disproportionality. Risk ratios require that the target group (e.g., Black students) be compared to another group (e.g., White students), however, there is a paucity of studies on the differential impact of using White students versus all other students as comparison groups. I analyzed data from 5,422 schools from the 2012 – 2014 academic school years across the United States by fitting two series of mixed models to account for the nested structure of the data. I evaluated the effect of using different comparison groups on risk ratio values as well as school disproportionate status. Results indicate that the use of all other students as a comparison group yields significantly higher mean risk ratio values over three years for Black students to receive at least one out-of-school suspension (OSS) by a factor of 2.621. The predicted odds of a school’s risk ratio value being significantly disproportionate (i.e., compared to a threshold value) increases by a factor of 1.790 when using all other students as a comparison group. The mean risk ratio values for Black students to receive at least one OSS were significantly higher in 2014 – 2015 than in 2012 – 2013, regardless of which comparison group is used. Implications for both policy makers and researchers are discussed in light of the findings and proposed legislation.

description: The development of BiPo detectors is dedicated to the measurement of extremely high radiopurity in $^{208}$Tl and $^{214}$Bi for the SuperNEMO double beta decay source foils. A modular prototype, called BiPo-1, with 0.8 $m^2$ of sensitive surface area, has been running in the Modane Underground Laboratory since February, 2008. The goal of BiPo-1 is to measure the different components of the background and in particular the surface radiopurity of the plastic scintillators that make up the detector. The first phase of data collection has been dedicated to the measurement of the radiopurity in $^{208}$Tl. After more than one year of background measurement, a surface activity of the scintillators of $\mathcal{A}$($^{208}$Tl) $=$ 1.5 $μ$Bq/m$^2$ is reported here. Given this level of background, a larger BiPo detector having 12 m$^2$ of active surface area, is able to qualify the radiopurity of the SuperNEMO selenium double beta decay foils with the required sensitivity of $\mathcal{A}$($^{208}$Tl) $

description: The atomic force microscope images surfaces by sensing the forces between a sharp tip and a sample. If the tip-sample interaction is dominated by short-range forces due to the formation of covalent bonds, the image of an individual atom should reflect the angular symmetry of the interaction. Here, we report on a distinct substructure in the images of individual adatoms on silicon (111)-(7×7), two crescents with a spherical envelope. The crescents are interpreted as images of two atomic orbitals of the front atom of the tip. Key for the observation of these subatomic features is a force-detection scheme with superior noise performance and enhanced sensitivity to short-range forces.

description: Background: Inherited pathogenic variants (PVs) in the CDKN2A gene are among the strongest known risk factors for cutaneous melanoma. Carriers are at high risks to develop multiple primary melanomas and other cancers, in particular pancreatic cancer. In this study, the CDKN2A testing, carried out in Sweden in the years 2015–2020, was evaluated. Materials and methods: Included families had (1) three or more cases of melanoma and/or pancreatic cancer, (2) two melanomas in first-degree relatives, the youngest case <55 years or (3) individuals with three or more multiple primary melanomas, the first before the age of 55 years, and no other affected family members. The included families had at least one affected member that had been tested for CDKN2A PVs. Results: In total, 403 families were included, whereof 913 family members had been diagnosed with cutaneous melanoma and 129 with pancreatic cancer, 33 (8.2%) were found to have PVs in CDKN2A. Frequencies ranged from 0.9% in families with only two melanomas to 43.2% in families with three or more melanoma cases and pancreatic cancer (p p = 0.040). In families with or without CDKN2A PVs, 37.6% and 10.0% had melanoma cases that had died from melanoma, respectively (p Discussion: Significant differences were seen in the frequencies of CDKN2A PVs, dependent on numbers or age at diagnosis of melanomas and diagnoses of pancreatic cancers in the family. Further, melanoma cases belonging to families that tested positive for CDKN2A PVs had a significantly higher mortality. To summarize, the current evaluation shows that, with adequately selected criteria to guide genetic testing, CDKN2A PVs are identified at significant frequencies. Identification of carrier families is of importance to ensure that members are enrolled in a preventive surveillance program.
CARE UNDER CARCERALITY: STRATEGIES OF WOMEN WITH INCARCERATED LOVED ONES

description: Mass incarceration disproportionately affects Black people, both in terms of who is literally caged, as well as who has to bear the emotional, social, and financial costs imposed by the incarceration of a loved one. Drawing on in-depth, semi-structured interviews with nine women with incarcerated loved ones, this paper advances understanding of the effects and reach of mass incarceration by exploring the strategies developed and employed by women with incarcerated male partners or sons as they care for their incarcerated loved ones. By focusing on this question, I seek to contribute to literature on how incarceration affects family members of incarcerated people. I draw on theories about gendered care work to build on Comfort’s concept of secondary prisonization and develop the idea of a double emotional burden carried by women with incarcerated loved ones. Findings demonstrate that the strategic behavioral adaptations women use to navigate control of the prison and care for their loved ones are manifestations of secondary prisonization. I argue that attention to the experiences, analyses, and agency of women caring for incarcerated loved ones is necessary to expand and nuance understandings of mass incarceration and its implications.

description: The growth of nanotube films on various substrates and surfaces is vital for applications in nanoscale functional devices. We report a simple and versatile boron (B) ink painting method that enables high-density boron nitride nanotube (BNNT) films with any desired pattern to be grown on, and firmly attached to, different surfaces. In the method, special B ink is first painted, sprayed or inkjet printed at desired location with required pattern, and then the ink layer is annealed in a nitrogen-containing atmosphere to form BNNT film. The B ink is a liquid mixture of ball-milled B particles, metal nitrate and ethanol. This is the first method capable of growing BNNTs on complex non-flat surfaces, which greatly broadens the potential application of BNNTs. For example, it is demonstrated that a BNNT coated steel mesh can separate water and oil on a microliter scale; a needle given an internal BNNT coating could greatly enhance microfluidic transport; and a coated screw could be used to minimize wear at the interface.

Subjects: subject: 530 Physik

description: Frequency-modulation atomic force microscopy (FMAFM) has proven to be a powerful method for imaging surfaces with true atomic resolution. However, the tip–sample forces are not directly accessible by FMAFM. Here, an algorithm to recover the tip–sample forces from the frequency shift curve is introduced and demonstrated with experimental data. Also, an intuititive connection between frequency shift Δf and tip–sample force gradient kts that simplifies the calculation of FMAFM images is established: Δf is a convolution of kts with a semispherical weight function.
The Sakhalin Village of Mizuho: Collective Memory and the Role of Non-state Actors in Local Governmental Policymaking Processes
Creators: name: Holbrook, Karina Ashley
Publisher: name: University of Chicago
Year: 2021

description: Today, non-state actors have an increasingly greater effect on policy, such as activist groups and individuals online; however, the relationship between non-state actors and policymakers is often understood as a producer-client relationship, with non-state actors framed as reacting, and therefore mainly passively consuming, the decisions of the policymaker. In particular, there is a lack of understanding of how non-state actors as subjects participate in the policymaking process, especially in non-Western countries. I aim to correct this knowledge gap by framing the non-state actor as an active policymaking agent, and through this, understand how non-state actors interact with and influence the policymaking process. My research analyzes how memory is preserved and utilized by non-state and state actors via a case study in Southern Sakhalin (Mizuho Village), where I conduct qualitative analysis of governmental and non-governmental resources in Russian, Japanese, and English. I find that community memory is created through trust and constant individual interactions, which is used by grassroots movements as a community rallying tool. Furthermore, these non-state actors operate outside of local governmental policy making; their greatest policymaking influence is on local governmental policy via absorption at a later date.
‘If you had to write a short diversity statement about yourself, what would you say?’: using diversity statements and introductory stories to develop holistic understandings of participants’ intersectional identities

description: There is an increasing focus on collecting more diverse demographic data from research participants but standard methodological approaches still hinder such efforts. This paper addresses the need for methodological improvements by advocating for the inclusion of self-written diversity statements in demographic surveys as a form of epistemic justice. Using examples from a large qualitative research study, I demonstrate the depth and richness of data that can be obtained through self-written diversity statements. In particular, I highlight the benefits of combining open-ended demographic questions and self-written diversity statements into holistic introductory stories to help capture the complexity of participants’ intersectional identities. Therefore, I argue that using such an approach gives participants the agency to choose how they are represented in research.

description: Squamous cell carcinoma of the anus (SCCA) is a rare malignancy with rising incidence, associated with human papilloma virus (HPV). Chemoradiotherapy (CRT) is the preferred treatment. The purpose was to investigate treatment failure, survival and prognostic factors after CRT. In this prospective observational study from a large regional centre, 141 patients were included from 2013 to 2017, and 132 were eligible for analysis. The main inclusion criteria were SCCA, planned radiotherapy, and performance status (ECOG) ≤2. Patient characteristics, disease stage, treatment, and treatment response were prospectively registered. Disease-free survival (DFS), overall survival (OS), and locoregional treatment failure after CRT were analysed. Hazard ratios (HRs) were estimated with Cox`s proportional hazards model. Median follow-up was 54 (range 6–71) months. Eighteen patients (14%) had treatment failures after CRT; of these 10 (8%) had residual tumour, and 8 (6%) relapse as first failure. The first treatment failure was locoregional (11 patients), distant (5 patients), and both (2 patients). Salvage abdomino-perineal resection was performed in 10 patients, 2 had resections of metastases, and 3 both. DFS was 85% at 3 years and 78% at 5 years. OS was 93% at 3 years and 86% at 5 years. In analyses adjusted for age and gender, HPV negative tumours (HR 2.5, p = 0.024), N3 disease (HR 2.6, p = 0.024), and tumour size ≥4 cm (HR 2.4, p = 0.038) were negative prognostic factors for DFS. State-of-the-art chemoradiotherapy for SCCA resulted in excellent outcomes, and improved survival compared with previous national data, with <15% treatment failures and a 3-year DFS of >80%.

Non-Police Mobile Crisis Response Team Programs: Reducing Unnecessary Police Interactions with Marginalized Populations
Creators: name: Hayford, Mary
Publisher: name: University of Chicago
Year: 2022

description: Non-police mobile crisis response team (MCR) programs are emerging as alternatives to policing with the potential to decrease interactions between police and marginalized populations. This paper investigates the feasibility of widespread implementation of MCR through a comparative case study of Crisis Assistance Helping Out On The Streets (CAHOOTS), Street Crisis Response Team (SCRT), and Support Team Assisted Response (STAR). The questions this paper seeks to address are: what are the successes and challenges associated with MCR? And, how can the lessons learned from CAHOOTS, STAR, and SCRT inform the establishment, design, and implementation of future MCR programs? To investigate this, interviews were conducted with MCR workers, MCR administrators, and academic experts; I also observed community meetings and relevant webinars. The findings suggest that clear division of responsibilities among city responses, community leadership, community partnerships, and gradually diverting funding from police are major factors affecting the successful implementation of MCR programs.

description: Highly accurate numerical results of phonon-induced two-electron spin relaxation in silicon double quantum dots are presented. The relaxation, enabled by spin-orbit coupling and the nuclei of 29Si (natural or purified abundance), is investigated for experimentally relevant parameters, the interdot coupling, the magnetic field magnitude and orientation, and the detuning. We calculate relaxation rates for zero and finite temperatures (100 mK), concluding that our findings for zero temperature remain qualitatively valid also for 100 mK. We confirm the same anisotropic switch of the axis of prolonged spin lifetime with varying detuning as recently predicted in GaAs. Conditions for possibly hyperfine-dominated relaxation are much more stringent in Si than in GaAs. For experimentally relevant regimes, the spin-orbit coupling, although weak, is the dominant contribution, yielding anisotropic relaxation rates of at least two orders of magnitude lower than in GaAs.
Supporting the Black Birthing Community in Chicago: A Study of the Capacity Building Needs of Black Doulas

description: Black birthing people and their babies have worse health outcomes than their white peers due to systemic factors such as poverty, implicit bias in medicine, and limited access to healthcare. Doulas, or continuous, non-clinical birth attendants, are a proven cost-effective means of improving birth outcomes and supporting birthing people through their pregnancy and delivery. Black doulas specifically deliver culturally relevant and community focused care to Black birthing people. In this study I utilize a qualitative approach to examine barriers that Black doulas in Chicago face in their delivery of care to Black clients. Analysis reveals a critical need for policy intervention to support the affordability of doula care for Black clients, as well as to support collaboration amongst Black doulas and with clinical care staff.
