Supplementary data confirming the relationship between critical Shields stress, grain size and bed slope

EARTH SURFACE PROCESSES AND LANDFORMS, Issue 11 2007
Gareth Pender
Abstract This article presents new experimental data on threshold conditions for motion of coarse uniform sediments. The experiments were conducted with 2·8 mm gravel in a 7·5 m long by 0·3 m wide flume and included measurements of hydraulic characteristics and rate of bed particle movement for a range of flows at different bed slopes. A reference transport method was used to define the beginning of sediment motion. Results from experiments with glass balls (diameters 6 and 9 mm) and coarse uniform gravels (17·5 and 38·6 mm) conducted by other researchers were used as an additional independent data set. The experimental data confirm the recent finding that the critical Shields stress for motion of coarse uniform sediment varies with both grain size and bed slope.

Oral Sex and Condom Use Among Young People In the United Kingdom

PERSPECTIVES ON SEXUAL AND REPRODUCTIVE HEALTH, Issue 1 2006
Nicole Stone
CONTEXT:: The development of UK national targets to reduce the transmission of HIV and other STDs has focused health promotion efforts on advocating the use of condoms during penetrative vaginal and anal sex. However, other behaviors that can facilitate STD transmission,such as oral sex and, in particular, fellatio,have received limited attention. METHODS:: Between 2003 and 2005, a sample of 1,373 full- and part-time students, primarily aged 16,18, completed questionnaires about their knowledge, attitudes and experiences related to sexual behavior and health. Chi-square tests were used to assess differences by sexual experience and gender. Supplementary data were obtained from sexual event diaries completed by 108 young people. RESULTS:: Fifty-six percent of survey respondents had experienced fellatio or cunnilingus, including 22% of those who had not yet engaged in penetrative intercourse. Of young people who had had vaginal intercourse, 70% had previously had oral sex. Among those who had experienced fellatio once, 17% had used a condom, but only 2% of respondents who had engaged in fellatio more than once reported consistent use. Reduced pleasure and lack of motivation, desire and forethought were reasons given for not using condoms during fellatio; hygiene, avoidance of the dilemma of whether to spit or swallow ejaculate, and taste were commonly cited as triggers for use. CONCLUSION:: Greater efforts are needed to publicize the risk of exposure to STDs that many young people face because of unprotected noncoital sexual activities before, as well as after, they enter into relationships involving intercourse.

Name change among offender patients: an English high security hospital sample

CRIMINAL BEHAVIOUR AND MENTAL HEALTH, Issue 4 2002
Birgit Völlm Clinical Research Fellow
Background There is scant literature on change of name among psychiatric patients but a more substantial amount on the use of aliases among offenders. No one to our knowledge has explored name changes among offender patients. Aim This study was undertaken to establish the prevalence of name change among high security hospital patients and to compare those who changed name with those who did not. Hypothesis It was hypothesized that name change would be associated with male gender, repeated offending and a diagnosis of personality disorder. Method The clinical records of all patients resident in one high security hospital on 31 January 2000 were searched. As all such patients are compulsorily detained, all name changes must be recorded. Any change prior to that date was also noted, together with basic demographic and diagnostic information; supplementary data were obtained from the special hospitals' case register. Results Seventy-one patients (17%) of the resident population changed names (exclusive of a woman changing her surname on marriage). Name changing was associated with disrupted upbringing. Patients with personality disorder were more likely to change names than those with psychosis, regardless of sex, age or ethnic group. Those with psychosis were more likely to select unusual or symbolic names. Conclusions On the evidence of previous literature, people from this serious offender patient population were more likely to change names than other psychiatric patients but less likely than non-mentally-disordered offenders. Changes by people with psychosis seemed related to their illness, whereas changes by those with personality disorder might reflect childhood disruptions in rearing patterns.

Coding Response to a Case-Mix Measurement System Based on Multiple Diagnoses

HEALTH SERVICES RESEARCH, Issue 4p1 2004
Colin Preyra
Objective. To examine the hospital coding response to a payment model using a case-mix measurement system based on multiple diagnoses and the resulting impact on a hospital cost model. Data Sources. Financial, clinical, and supplementary data for all Ontario short stay hospitals from years 1997 to 2002. Study Design. Disaggregated trends in hospital case-mix growth are examined for five years following the adoption of an inpatient classification system making extensive use of combinations of secondary diagnoses. Hospital case mix is decomposed into base and complexity components. The longitudinal effects of coding variation on a standard hospital payment model are examined in terms of payment accuracy and impact on adjustment factors. Principal Findings. Introduction of the refined case-mix system provided incentives for hospitals to increase reporting of secondary diagnoses and resulted in growth in highest complexity cases that were not matched by increased resource use over time. Despite a pronounced coding response on the part of hospitals, the increase in measured complexity and case mix did not reduce the unexplained variation in hospital unit cost nor did it reduce the reliance on the teaching adjustment factor, a potential proxy for case mix. The main implication was changes in the size and distribution of predicted hospital operating costs. Conclusions. Jurisdictions introducing extensive refinements to standard diagnostic related group (DRG)-type payment systems should consider the effects of induced changes to hospital coding practices. Assessing model performance should include analysis of the robustness of classification systems to hospital-level variation in coding practices. Unanticipated coding effects imply that case-mix models hypothesized to perform well ex ante may not meet expectations ex post. [source]


Precipitation trends over the Russian permafrost-free zone: removing the artifacts of pre-processing

INTERNATIONAL JOURNAL OF CLIMATOLOGY, Issue 6 2001
Pavel Ya.
Abstract Rain gauge changes, changes in the number of observations per day, and inconsistent corrections to observed precipitation data during the 20th century of the meteorological network of the former Soviet Union make it difficult to address the issue of century time-scale precipitation changes. In this paper, we use daily and sub-daily synoptic data to account for the effects of these changes on the instrumental homogeneity of precipitation measurements over the Russian permafrost-free zone (RPF, most populous western and central parts of the country). Re-adjustments that were developed during this assessment allow us to (a) develop a system of scale corrections that remove the inhomogeneity owing to wetting/observation time changes over most of the former Soviet Union during the past century, and (b) to estimate precipitation trends over the RPF, reconciling previously contradictory results. The trend that emerges is an increase of about 5% per century. This estimate can be further refined after a more comprehensive set of supplementary data (precipitation type and wind) and metadata (information about the exposure of meteorological sites) is employed.

The Real Story of Housing Prices in Australia from 1970 to 2003

THE AUSTRALIAN ECONOMIC REVIEW, Issue 3 2005
Peter Abelson
Despite the popular and public policy interest in housing prices, there have been few reliable published data for housing prices in Australia. In this article we aim to provide an authoritative account of prices for houses and apartments (units) in Australia from 1970 to 2003. Where possible we draw on data from land title offices or on studies that draw on these data, but we also draw on supplementary data in some cases. The first part of the article describes the major data sources of Australian house prices. The main body of the article provides our best estimates of median house and unit prices and real price indices in the capital cities and in the rest of Australia along with explanations for their derivations. We also estimate how improvements in housing quality have influenced real house prices. [source]


Progress in the Development of a High Performance Airborne Digital Sensor

THE PHOTOGRAMMETRIC RECORD, Issue 96 2000
P. Fricker
Joint development work by LH Systems and Deutsches Zentrum für Luft- und Raumfahrt (German Aerospace Center) has produced encouraging results using forward, nadir and backward looking linear arrays on the focal plane to provide panchromatic imagery and geometric information, supplemented by further arrays to acquire multispectral imagery suitable for both high precision photogrammetric mapping and image processing for interpretative purposes. The geometric characteristics of line scanner imagery necessitate line-by-line rectification for aircraft tilts and shifts. Satisfactory execution of this process is enhanced by using supplementary data from high performance, on-board GPS and inertial measurement systems. Similarly, high demands are placed on other sub-systems, such as the camera mount, lens, electronics and storage technology. In addition to rectification for aircraft tilts and shifts, rectification for terrain characteristics is also required in order to generate colour and false colour composite images, since the various multispectral arrays are in different places on the focal plane. The special geometry affects triangulation. Thereafter, the imagery can be processed using existing software packages from both photogrammetry and remote sensing. The concept has been demonstrated in several successful test flights and the production model is scheduled for market introduction at the ISPRS Congress in July 2000. The imagery from the new sensor will fulfil many market requirements between the highest resolution film imagery (<0.1 m) and high resolution space imagery (1m to 10 m). The sensor's unique blend of multispectral information with high quality geometric information will give rise to numerous new applications. [source]
