    This document explores Cheryl Frances-Hoad’s song cycle Magic Lantern Tales, as a highlight of her oeuvre as well as of contemporary art song. Each song in the cycle, and a select few of Frances-Hoad’s other vocal works, will be studied from a performer’s perspective to identify Frances-Hoad’s compositional approach to song, as well as her individual style in Magic Lantern Tales. The document examines stylistic features and unifying elements of Frances-Hoad’s vocal repertoire, with particular emphasis on music/text relationships. This document is motivated by a desire to raise awareness of Frances-Hoad’s vocal literature. Serving as an introduction to Frances-Hoad and her vocal music, this document offers a biography of the composer and a music/text analysis of some of her vocal works, specifically Magic Lantern Tales. For each of her songs examined, background, compositional style, and text setting will be considered. A study of each of these elements, combined and in conjunction with the context of the poetry, will reveal Frances-Hoad’s approach to portraying a story, especially through text painting. It will also explore the role this particular cycle plays as a historical commemoration of World War I. As the proverbial saying goes, “Tell me and I forget, teach me and I may remember, involve me and I learn.” Music not only involves, but has the power to move and change us. The commemorative nature of this song cycle in accordance with compositional and performance devices that carry the power of the words, and ultimately the stories, to the hearts of the listener, can create an experience of remembrance that ensures historical preservation through music. Ultimately my intention is to demonstrate the significance of Magic Lantern Tales to the genre of modern art song, and perhaps more importantly, to demonstrate Cheryl Frances-Hoad’s merit as a living song composer. In addition, this study of Frances-Hoad’s compositional style and approach to storytelling will hopefully bring a wider awareness of her vocal music as a whole, and will promote more frequent performances of this music among students and professionals alike

    The long-term health effects of attending a selective school: a natural experiment

    Background: Education is widely associated with better physical and mental health, but isolating its causal effect is difficult because education is linked with many socioeconomic advantages. One way to isolate education’s effect is to consider environments where similar students are assigned to different educational experiences based on objective criteria. Here we measure the health effects of assignment to selective schooling based on test score, a widely debated educational policy. Methods: In 1960s Britain, children were assigned to secondary schools via a test taken at age 11. We used regression discontinuity analysis to measure health differences in 5039 people who were separated into selective and non-selective schools this way. We measured selective schooling’s effect on six outcomes: mid-life self-reports of health, mental health, and life limitation due to health, as well as chronic disease burden derived from hospital records in mid-life and later life, and the likelihood of dying prematurely. The analysis plan was accepted as a registered report while we were blind to the health outcome data. Results: Effect estimates for selective schooling were as follows: self-reported health, 0.1 worse on a 4-point scale (95%CI − 0.2 to 0); mental health, 0.2 worse on a 16-point scale (− 0.5 to 0.1); likelihood of life limitation due to health, 5 percentage points higher (− 1 to 10); mid-life chronic disease diagnoses, 3 fewer/100 people (− 9 to + 4); late-life chronic disease diagnoses, 9 more/100 people (− 3 to + 20); and risk of dying before age 60, no difference (− 2 to 3 percentage points). Extensive sensitivity analyses gave estimates consistent with these results. In summary, effects ranged from 0.10–0.15 standard deviations worse for self-reported health, and from 0.02 standard deviations better to 0.07 worse for records-derived health. However, they were too imprecise to allow the conclusion that selective schooling was detrimental. Conclusions: We found that people who attended selective secondary school had more advantaged economic backgrounds, higher IQs, higher likelihood of getting a university degree, and better health. However, we did not find that selective schooling itself improved health. This lack of a positive influence of selective secondary schooling on health was consistent despite varying a wide range of model assumptions

    Measurement of the position resolution of the Gas Pixel Detector

    The Gas Pixel Detector was designed and built as a focal plane instrument for X-ray polarimetry of celestial sources, the last unexplored subtopics of X-ray astronomy. It promises to perform detailed and sensitive measurements resolving extended sources and detecting polarization in faint sources in crowded fields at the focus of telescopes of good angular resolution. Its polarimetric and spectral capability were already studied in earlier works. Here we investigate for the first time, with both laboratory measurements and Monte Carlo simulations, its imaging properties to confirm its unique capability to carry out imaging spectral-polarimetry in future X-ray missions.Comment: Submitted to Nuclear Instruments and Methods in Physics Research Section A; 15 figures, 3 table

    A core outcome set for randomised controlled trials of physical activity interventions: development and challenges.

    BACKGROUND: Core outcome sets are standardised sets of outcomes that should be collected and reported for all clinical trials. They have been widely developed and are increasingly influential in clinical research, but despite this, their use in public health has been limited to date. The aim of this study was to develop a core outcome set for public health trials evaluating interventions to promote physical activity in the general adult population. METHODS: The core outcome set was developed using a three-stage approach: stage one: a review of literature to identify potential domains for inclusion in the core outcome set; stage two: a Delphi survey was carried out to reach consensus about which outcome domains to include in the core outcome set; and stage three: a second Delphi survey was conducted to determine how best to measure the outcome domains included in the core outcome set. RESULTS: A classification of 13 outcome domains of physical activity was developed (stage one). Twenty people completed round one of the first Delphi survey (stage two), reaching a consensus to include two domains in the core outcome set, 'device-based level of physical activity' (80.0%, n = 16) and 'health-related quality of life' (70.0%, n = 14). No further consensus on the remaining outcome domains was reached in round two. Nineteen people completed the second Delphi survey (stage three). Participants rated the accelerometer (mean rating = 3.89, on a scale of 1 (do not recommend) to 5 (highly recommend)) as the best device to measure level of physical activity, and the EQ-5D (73.7%, n = 14) as the most appropriate measure of health-related quality of life. CONCLUSIONS: This study has made progress towards the development of a core outcome set for use in physical activity trials, however, there was limited consensus about which domains to include. The development of the core outcome set was challenged by the need for trial-specific outcomes, and the complexities of collecting, processing and reporting device-based data

    The effect of lymphatic microsurgical preventive healing approach (LYMPHA) on the development of upper-extremity lymphedema following axillary lymph node dissection in breast cancer patients

    Background/Objective: Lymphedema following axillary lymph node dissection (ALND) is a common complication that can negatively impact quality of life as it reduces the functional capacity of the affected arm. It can also predispose patients to serious infectious complications such as limb cellulitis and development of malignancy. The lymphatic microsurgical preventive healing approach (LYMPHA procedure) involves the creation of a lymphatic‐to‐venous bypass at the time of axillary lymph node dissection (ALND) as a means of preventing lymphedema. The goal of our study is to assess the effect of LYMPHA on the development of clinical and subjective post‐operative lymphedema. Methods: This is a prospective longitudinal study in patients with breast cancer who underwent ALND with or without LYMPHA. The incidence of lymphedema was compared between ALND alone and ALND with LYMPHA using descriptive statistics. Limb circumference of both affected and unaffected limbs were measured and used to calculate limb volume by using an equation that converts limb circumference (cm) to volume (cc). Lymphedema was defined as a volume difference of ≥10% between the affected and unaffected limb. Patient symptoms were also assessed and compared between the 2 groups. Patient demographics including age, preoperative body mass index (BMI), smoking history, comorbidities, receipt of neoadjuvant or adjuvant chemotherapy, and receipt of adjuvant radiation were compared between the groups. Results: In our cohort of 139 patients, 104 underwent ALND with LYMPHA, while 35 underwent ALND alone. Of these, 52.5% of patients had documented interlimb circumference measurements. The mean age was 52.6 years old, mean BMI was 30.16 kg/m2, 4 patients (2.9%) had pre‐operative radiation, 102 patients (73.4 %) had post‐operative radiation, 86 patients (61.9 %) had neoadjuvant chemotherapy, 41 and 58 patients (41.7 %) had adjuvant chemotherapy. There were no significant differences between the 2 groups in the above demographics and treatment variables, except those who underwent ALND alone had a significantly higher incidence of diabetes mellitus (25.7% patients with ALND alone vs 11.5% LYMPHA patients (p=0.043)). Based on patient reported symptoms and the need to initiate complete decongestive therapy, 57.1% (n=20) of patients who underwent ALND alone developed lymphedema compared to 26.9% (n=28 patients) of those who had ALND with LYMPHA (p=0.0011). When comparing the relative volume difference, 57.1% (n=8) of ALND alone patients developed lymphedema versus 20.3% (n=12) of LYMPHA patients (p=0.0055). Conclusions: Our data support the universal use of LYMPHA at the time of ALND as a means of preventing upper extremity lymphedema. Further studies are needed to evaluate quality of life and functional differences between those who had LYMPHA and those who did not

    A quantum Monte Carlo study of the one-dimensional ionic Hubbard model

    Full text link
    Quantum Monte Carlo methods are used to study a quantum phase transition in a 1D Hubbard model with a staggered ionic potential (D). Using recently formulated methods, the electronic polarization and localization are determined directly from the correlated ground state wavefunction and compared to results of previous work using exact diagonalization and Hartree-Fock. We find that the model undergoes a thermodynamic transition from a band insulator (BI) to a broken-symmetry bond ordered (BO) phase as the ratio of U/D is increased. Since it is known that at D = 0 the usual Hubbard model is a Mott insulator (MI) with no long-range order, we have searched for a second transition to this state by (i) increasing U at fixed ionic potential (D) and (ii) decreasing D at fixed U. We find no transition from the BO to MI state, and we propose that the MI state in 1D is unstable to bond ordering under the addition of any finite ionic potential. In real 1D systems the symmetric MI phase is never stable and the transition is from a symmetric BI phase to a dimerized BO phase, with a metallic point at the transition

    IntroductionA national consensus panel was convened to develop recommendations on future directions for home‐based dementia care (HBDC).MethodsThe panel summarized advantages and challenges of shifting to HBDC as the nexus of care and developed consensus‐based recommendations.ResultsThe panel developed five core recommendations: (1) HBDC should be considered the nexus of new dementia models, from diagnosis to end of life in dementia; (2) new payment models are needed to support HBDC and reward integration of care; (3) a diverse new workforce that spans the care continuum should be prepared urgently; (4) new technologies to promote communication, monitoring/safety, and symptoms management must be tested, integrated, and deployed; and (5) targeted dissemination efforts for HBDC must be employed.DiscussionHBDC represents a promising paradigm shift to improve care for those living with dementia and their family caregivers: these recommendations provide a framework to chart a course forward for HBDC.HighlightsFive core BrightFocus Foundation panel recommendations:Home‐based dementia care should be considered the nexus of new long‐term care models.New payment models are needed to stimulate, reward, and support home care practices.A skilled new workforce spanning long‐term care needs to be developed and equipped.New technologies to promote best practices must be tested, integrated, and deployed.Value propositions and improved public health communication are needed.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/152597/1/alzjjalz201710006.pd

    Predicting default probabilities and implementing trading strategies for emerging markets bond portfolios

    Get PDF
    In this paper we address two main issues: the computation of default probability implicit in emerging markets bond prices and the impact on portfolio risks and returns of expected changes in default probability. Using a reduced-form model, weekly estimates of default probabilities for US Dollar denominated Global bonds of twelve emerging markets are extrapolated for the sample period 1997-2001. The estimation of a logit type econometric model shows that weekly changes of the default probabilities can be explained by means of some capital markets factors. Recursively estimating the logit model using rolling windows of data, out-of-sample forecasts for the dynamics of default probabilities are generated and used to form portfolios of bonds. The practical application provides interesting results, both in terms of testing the ability of a naive trading strategy based on model forecasts to outperform a ”customized benchmark”, and in terms of the model ability to actively manage the portfolio risk (evaluated in terms of VaR) with respect to a constant proportion allocation
