Evaluation of ERBE scanner pointing accuracy based upon a coastline detection algorithm

Measurements from the Earth Radiation Budget Experiment (ERBE) scanning radiometers must be accurately located at the top of the Earth's atmosphere for proper interpretation of derived longwave and shortwave components of the Earth radiation field. The accuracy of the location calculations is affected by the orbit characteristics and attitude control systems of the three spacecraft, ERBS, NOAA-9, and NOAA-10. A technique was developed which makes use of the longwave scanner measurements to detect the thermal gradients at the boundaries of ocean and land masses. By analyzing many such coastline boundaries, estimates of the overall accuracy of the scanner measurement location calculations have been derived for the three satellites. The resulting measurement location errors are found to be smaller than the resolution of the radiometers, and this accuracy is well within the required location knowledge for useful science analysis of the ERBE scanner data

Monongalia County Court Records

The purpose of this paper is to invite the attention of the bar of this state to an undertaking which is expected to prove interesting and valuable to that group. A thorough examination and classification of the court records of Monongalia County, West Virginia, is being conducted under the direction of West Virginia University and the Committee on Legal History of the State Bar Association. The object is to render the material contained in the records available for historical and legal research

A CSO Search for ll-C3_3H+^+: Detection in the Orion Bar PDR

The results of a Caltech Submillimeter Observatory (CSO) search for $l$-C$_3$H$^+$, first detected by Pety et al. (2012) in observations toward the Horsehead photodissociation region (PDR), are presented. A total of 39 sources were observed in the 1 mm window. Evidence of emission from $l$-C$_3$H$^+$ is found in only a single source - the Orion Bar PDR region, which shows a rotational temperature of 178(13) K and a column density of 7(2) x $10^{11}$ cm$^{-2}$. In the remaining sources, upper limits of ~10$^{11} - 10^{13}$ cm$^{-2}$ are found. These results are discussed in the context of guiding future observational searches for this species.Comment: 9 pages, 8 figures, 4 table

The Effect of Serostatus on HIV Risk Behaviour Change among Women Sex Workers in Miami, Florida

HIV prevention and risk reduction are especially salient and timely issues for women, particularly among those who are drug-involved or who exchange sex for drugs or money. Studies suggest that HIV-prevention measures can be effective with highly vulnerable women, and have the potential to produce significant reductions in risk behaviours among both HIV-negative and HIV-positive women. Within this context, this paper examines risk behaviours and HIV serostatus among 407 drug-involved women sex workers in Miami, Florida, and investigates the effects of participation in HIV testing, counselling, and a risk-reduction intervention on subsequent behavioural change among this population. Overall, at follow-up, the HIV-positive women were 2.4 times more likely than the HIV-negative women to have entered residential treatment for drug abuse, 2.2 times more likely to have decreased the number of their sex partners, 1.9 times more likely to have decreased the frequency of unprotected sex, 1.9 times more likely to have reduced their levels of alcohol use, and 2.3 times more likely to have decreased their crack use. These data support the importance of HIV testing and risk-reduction programmes for drug-involved women sex workers

The Connections of Mental Health Problems, Violent Life Experiences and the Social Milieu of the \u27Stroll\u27 with the HIV Risk Behaviors of Female Street Sex Workers

This paper examines the connections of mental health, victimization, and sexual risk behaviors among a sample of 278 street-based female sex workers in Miami. Using targeted sampling strategies, drug-using sex workers were recruited into an HIV prevention research program. Data were collected by trained interviewers, and focused on drug use and sexual risk for HIV, childhood abuse, recent victimization, and mental health. More than half of the participants reported histories of physical (51.1%) or sexual (53.1%) abuse as children, 37.4% were classified with moderate or severe anxiety symptoms, and 52.9% had symptoms of moderate or severe depression. Logistic regression analyses demonstrated significant associations between mental health issues and engagement in recent unprotected vaginal and oral sex. The program development and policy implications of these findings are discussed

Serologic Evidence of Widespread Everglades Virus Activity in Dogs, Florida

Everglades virus (EVEV), an alphavirus in the Venezuelan equine encephalitis complex, circulates among rodents and vector mosquitoes in Florida and occasionally infects humans. It causes febrile disease, sometimes accompanied by neurologic manifestations. Although previous surveys showed high seroprevalence in humans, EVEV infections may be underdiagnosed because the disease is not severe enough to warrant a clinic visit or the undifferentiated presentations complicate diagnosis. Documented EVEV activity, as recent as 1993, was limited to south Florida. Using dogs as sentinels, a serosurvey was conducted to evaluate whether EVEV circulated recently in Florida and whether EVEV's spatial distribution parallels that of the mosquito vector, Culex cedecei. Four percent of dog sera contained neutralizing EVEV antibodies, and many seropositive animals lived farther north than both recorded EVEV activity and the principal vector. These results indicate that EVEV is widespread in Florida and may be an important, unrecognized cause of human illness

Developing Healthy Kids in Healthy Communities: Eight Evidence-based Strategies for Preventing High-risk Behaviour.

Australian youth engage in behaviour that threatens their health and wellbeing. National surveys report that about a third of young Australians have tried an illicit drug. High rates of substance use and risky sexual behaviour among young Australians suggest that effective prevention efforts based on empirical evidence need to be expanded. Church-associated organisations are an untapped resource that could be used to improve the health and welfare of young people. We describe eight evidence-based elements to consider in designing strategies to prevent high-risk behaviour in young people
