Inter-analyst variability in swimming competition analysis

This paper quantified the inter-analyst variability in the time at which a swimmer reached a certain distance in a race, which is a key measure in swimming competition analysis. Prior to this paper coaches had assumed that differences in these times were solely due to changes in the swimmer’s performance. This assumption was tested by asking four trained and experienced British Swimming analysts to calculate the time at which a swimmer reached four distances in ten randomly selected 100 m races. The inter-analyst variability was found to be between 0.02 s and 0.34 s

Two Dimensional Atomically Thin Materials and Hybrid Superconducting Devices

In this thesis a variety of topics concerning 2D materials that have been separated from bulk layered crystals are discussed. Throughout the thesis, single and few layers of graphene, fluorinated graphene, MoS2 and WS2 are used. Two new methods of freely suspending 2D materials are presented as well as a method of removing the background from optical images. This aids contrast measurements for the determination of the number of layers. Fluorinated graphene is found to be sensitive to beta radiation; the resistance of fluorinated graphene transistors is shown to decrease upon exposure to the radiation. This happens due to the carbon-fluorine bond breaking. The sp3 hybridised structure of the fluorinated graphene is reduced back into the sp2 hybridised structure of pristine graphene. The superconducting properties of molybdenum-rhenium are characterised. It is shown to have a transition temperature of 7.5 K. It is also discovered that the material has a resistance to hydrofluoric acid; the acid etches nearly all other superconducting materials. This makes MoRe a possible candidate to explore superconductivity in conjunction with high mobility suspended graphene. To see if the material is compatible with graphene, a supported Josephson junction is fabricated. A proximity induced super current is sustained through the junction up to biases of ∼ 200 nA. The temperature dependence of the conductivity is measured for both suspended MoS2 and WS2 on a hexagonal boron nitride substrate. The dominant hopping mechanism that contributes to the conductivity at low temperatures is found to be Mott variable range hopping, with the characteristic T−1/3 dependence. The hopping transport is due to impurities that are intrinsic to the crystals, this is confirmed by comparing the results with those of supported devices on SiO2.EPSR

The Homeless of Massachusetts: An Analysis of the 1990 U.S. Census S-Night Data

This article, which examines epidemiological and policy correlates of homeless populations in 351 Massachusetts towns and cities, is based on an analysis of data from the 1990 U.S. census. It reviews the reliability of the most recent census data, reports findings on the distribution and characteristics of homeless persons in Massachusetts, and presents preliminary correlational findings on the impact of key demographic conditions and policies. The report includes a meta-analysis of several studies that monitored the Census Bureaus street counts. It is estimated that 42.6 percent of the homeless on the streets in selected urban areas were counted by the census. This finding, as well as the results of a regression model that accounted for 68 percent of the variation in street rates in twenty Massachusetts cities with populations of more than 50,000, was used to compute adjusted rates for the remaining towns and cities. Overall adjusted rates for Massachusetts, Boston, and selected areas compared well with independent estimates and counts. The study suggests that at least 10,155 Massachusetts residents were homeless in 1990

Changing Patterns of Acute Psychiatric Hospitalization under a Public Managed Care Program

This study evaluates changes in patterns of acute psychiatric hospitalization under Massachusetts\u27 Medicaid-funded Mental Health and Substance Abuse (MMHSA) carve-out program. The data consists of the Case Mix Database, for FY 1996 and FY 1997, compiled by the state\u27s Division of Health Care Finance and Policy, on all acute hospital episodes in the state. Key comparisons involve hospital utilization during the nine months preceding the 1996 implementation of the current expanded carve-out program and the subsequent 15 months of its implementation. Secondary comparisons are made between patients funded by the state\u27s two major Medicaid programs, its behavioral carve-out and its contracted HMOs, as well as with other cohorts. Key variables include demographic and diagnostic measures, length of stay and recidivism, source of referral, insurance, socioeconomic characteristicso f zip code of residence,a nd transfers between programs. Findings include lower than anticipated rates of transfer from the free-care program to the behavioral carve-out program and higher than average and increasing levels of recidivism for patients in the behavioral carve-out program. The final model, based on a Cox regression analysis, correctly predicts 62.9% of the rehospitalization experience, a statistically significant portion of which was attributable to type of insurance coverage. The study also shows that neither the carve-out nor the HMO model of managed care are clearly superior one another
