Election timing as a predictor of electoral outcomes in public school bond elections in Missouri

Field of study: Educational leadership and policy analysis.Dr. Timothy Wall, Dissertation Supervisor.Includes vita."May 2018."This quantitative study sought to investigate the differences in the electoral outcomes of school bond elections in Missouri from 2009-2016 based on election timing. The researcher utilized election timing theory as a framework for the study. Data from Missouri school bond elections was compiled from online databases, the Missouri State Auditor's office, and archived newspaper reports. Results suggest that differences exist in electoral outcomes for school bond issues based on election timing. The study concludes with recommendations for Missouri school administrators, designed to aid in the successful passage of school bond issues.Includes bibliographical references (pages 115-124)

Inverse modeling of the global methyl chloride sources

Inverse modeling using the Bayesian least squares method is applied to better constrain the sources and sinks of atmospheric methyl chloride (CH3Cl) using observations from seven surface stations and eight aircraft field experiments. We use a three-dimensional global chemical transport model, the GEOS-Chem, as the forward model. Up to 39 parameters describing the continental/hemispheric and seasonal dependence of the major sources of CH3Cl are used in the inversion. We find that the available surface and aircraft observations cannot constrain all the parameters, resulting in relatively large uncertainties in the inversion results. By examining the degrees of freedom in the inversion Jacobian matrix, we choose a reduced set of parameters that can be constrained by the observations while providing valuable information on the sources and sinks. In particular, we resolve the seasonal dependence of the biogenic and biomass-burning sources for each hemisphere. The in situ aircraft measurements are found to provide better constraints on the emission sources than surface measurements. The a posteriori emissions result in better agreement with the observations, particularly at southern high latitudes. The a posteriori biogenic and biomass-burning sources decrease by 13 and 11% to 2500 and 545 Gg yr-1, respectively, while the a posteriori net ocean source increases by about a factor of 2 to 761 Gg yr-1. The decrease in biomass-burning emissions is largely due to the reduction in the emissions in seasons other than spring in the Northern Hemisphere. The inversion results indicate that the biogenic source has a clear winter minimum in both hemispheres, likely reflecting the decrease of biogenic activity during that season.

First-order sidebands in circuit QED using qubit frequency modulation

Sideband transitions have been shown to generate controllable interaction between superconducting qubits and microwave resonators. Up to now, these transitions have been implemented with voltage drives on the qubit or the resonator, with the significant disadvantage that such implementations only lead to second-order sideband transitions. Here we propose an approach to achieve first-order sideband transitions by relying on controlled oscillations of the qubit frequency using a flux-bias line. Not only can first-order transitions be significantly faster, but the same technique can be employed to implement other tunable qubit-resonator and qubit-qubit interactions. We discuss in detail how such first-order sideband transitions can be used to implement a high fidelity controlled-NOT operation between two transmons coupled to the same resonator.Comment: 15 pages, 5 figure

Nurse telephone triage for same day appointments in general practice: multiple interrupted time series trial of effect on workload and costs

OBJECTIVE: To compare the workloads of general practitioners and nurses and costs of patient care for nurse telephone triage and standard management of requests for same day appointments in routine primary care. DESIGN: Multiple interrupted time series using sequential introduction of experimental triage system in different sites with repeated measures taken one week in every month for 12 months. SETTING: Three primary care sites in York. Participants: 4685 patients: 1233 in standard management, 3452 in the triage system. All patients requesting same day appointments during study weeks were included in the trial. MAIN OUTCOME MEASURES: Type of consultation (telephone, appointment, or visit), time taken for consultation, presenting complaints, use of services during the month after same day contact, and costs of drugs and same day, follow up, and emergency care. RESULTS: The triage system reduced appointments with general practitioner by 29-44%. Compared with standard management, the triage system had a relative risk (95% confidence interval) of 0.85 (0.72 to 1.00) for home visits, 2.41 (2.08 to 2.80) for telephone care, and 3.79 (3.21 to 4.48) for nurse care. Mean overall time in the triage system was 1.70 minutes longer, but mean general practitioner time was reduced by 2.45 minutes. Routine appointments and nursing time increased, as did out of hours and accident and emergency attendance. Costs did not differ significantly between standard management and triage: mean difference £1.48 more per patient for triage (95% confidence interval -0.19 to 3.15). CONCLUSIONS: Triage reduced the number of same day appointments with general practitioners but resulted in busier routine surgeries, increased nursing time, and a small but significant increase in out of hours and accident and emergency attendance. Consequently, triage does not reduce overall costs per patient for managing same day appointments

China Maritime Report No. 3: China’s Distant-Ocean Survey Activities: Implications for U.S. National Security

Today, the People’s Republic of China (PRC) is investing in marine scientific research on a massive scale. This investment supports an oceanographic research agenda that is increasingly global in scope. One key indicator of this trend is the expanding operations of China’s oceanographic research fleet. On any given day, 5-10 Chinese “scientific research vessels” (科学考查船) may be found operating beyond Chinese jurisdictional waters, in strategically-important areas of the Indo-Pacific. Overshadowed by the dramatic growth in China’s naval footprint, their presence largely goes unnoticed. Yet the activities of these ships and the scientists and engineers they embark have major implications for U.S. national security. This report explores some of these implications. It seeks to answer basic questions about the out-of-area—or “distant-ocean” (远洋)—operations of China’s oceanographic research fleet. Who is organizing and conducting these operations? Where are they taking place? What do they entail? What are the national drivers animating investment in these activities?https://digital-commons.usnwc.edu/cmsi-maritime-reports/1002/thumbnail.jp

China\u27s Evolving Surface Fleet

The missile fast-attack craft and amphibious fleets of the People\u27s Liberation Army (PLA) Navy (PLAN) have undergone significant modernization over the past fifteen years. The capabilities of both categories of vessels have improved even if their actual numbers have not increased dramatically. Examined from the perspective of PLA doctrine and training, the missions of these forces represent the PLAN\u27s past, present, and future.https://digital-commons.usnwc.edu/cmsi-red-books/1013/thumbnail.jp

‘The Dream and Aspirations of Teaching’: English Teachers’ Perspectives on Sustaining the Motivation to Teach

This paper reports on selected findings from a research study with 211 secondary school English teachers in New South Wales (NSW), Australia. A questionnaire was utilised to gather evidence of teachers' perspectives on teaching, including the continued salience of their initial motivations for entering the teaching profession and their career intentions. The relationship between the durability of initial intrinsic and altruistic motivations to teach and teachers' commitment to the profession over time has been implicated in career foreclosure and teacher turnover. This research investigated the relationship between teacher motivation, levels of satisfaction with teaching and career intentions for 'invested teachers' (Glazer, 2017) with ten or more years of service. The findings confirmed the predominance of altruistic and intrinsic motivations in the initial decision to become a teacher. One third of experienced teachers had not maintained their original motivations. More than one third were 'unsure', 'dissatisfied' or 'very dissatisfied' with teaching. Twenty per cent reported that they would only be teaching for another one to five years. The findings identify a range of extrinsic factors influencing declining teacher motivation, wellbeing, perceived self-efficacy, job satisfaction and early exit career intentions. The data point to flagging levels of motivation as risk indicators for teachers' decision-making about their future in the profession
