    In 1985, NASA initiated an innovative effort called Centers for the Commercial Development of Space (CCDS). The CCDS program was designed to increase private-sector interest and investment in space-related activities, while encouraging U.S. economic leadership and stimulating advances in promising areas of research and development. Research conducted in the Centers handling the following areas is summarized: materials processing; life sciences; remote sensing; automation and robotics; space propulsion; space structures and materials; and space power

    Correlates of undefined cause of injury coded mortality data in Australia

    The objective of this research was to identify the level of detail regarding the external causes of death in Australia and ascertain problematic areas where data quality improvement efforts may be focused. The 2003 national mortality dataset of 12591 deaths with an external cause of injury as the underlying cause of death (UCOD) or multiple cause of death (MCOD) based on ICD-10 code assignment from death certificate information was obtained. Logistic regression models were used to examine the precision of coded external cause of injury data.---- It was found that overall, accidents were the most poorly defined of all intent code blocks with over 30% of accidents being undefined, representing 2314 deaths in 2003. More undefined codes were identified in MCOD data than for UCOD data. Deaths certified by doctors were more likely to use undefined codes than deaths certified by a coroner or government medical office.---- To improve the quality of external cause of injuries leading to or associated with death, certifiers need to be made aware of the importance of documenting all information pertaining to the cause of the injury and the intent behind the incident, either through education or more explicit instructions on the death certificate and accompanying instructional materials. It is important that researchers are aware of the validity of the data when they make interpretations as to the underlying causes of fatal injuries and causes of injury associated with deaths

    Integration of organic poultry in whole farm systems: manure nutrient budgets

    This report was presented at the UK Organic Research 2002 Conference. The aim of this project was to examine how rotations incorporating organic poultry use the cycling of nutrients between soil, crops and birds. Poultry studies have measured nutrient values of manure in slow growing meat birds at about day 81 when fed typical broiler rations versus “Label Rouge” rations. Nutrient (N, P, K) balances were constructed to assess the viability of integrating poultry production within a theoretical organic rotation. The readilyplant- available nitrogen in manure from Ross 308 birds fed either presumed non-limiting rations or Label Rouge rations was within the range reported for intensive broilers. For ISA 657 birds, the manure readily-plant-available nitrogen was similar to the mean value reported for broilers, when fed presumed non limiting rations, but towards the lower range when fed Label Rouge rations. As breed growth and feed intakes differ it is suggested that to optimise the utilisation of nutrients, the nutrient content of table bird manures should be checked prior to land application. The nutrient budgets were similar for N and P regardless of the length of rotation or form of poultry production. On average, there was a surplus of 85 kg/ha N over all the scenarios. There tended to be a deficit of K in all scenarios (average: 10 kg/ha)

    "I think maybe 10 years seems a bit long." Beliefs and attitudes of women who had never used intrauterine contraception

    Aim To explore, in a general practice setting, the concerns, beliefs and attitudes about intrauterine contraception (IUC) reported by women, who had never used the methods. Methods We used a sequential mixed-method (QUAL/quant) approach. A pragmatic, self-selecting sample of 30 women, aged 18–46 years, who had never used IUC), was recruited through seven general practices in South East England. Themes arising from qualitative interviews were used to construct a quantitative survey, completed by a pragmatic sample of 1195 women, aged 18–49 years, attending 32 general practices in the same region, between February and August 2015. Results Qualitative themes were concerns about the long-acting nature of IUC, concerns about body boundaries, and informal knowledge of IUC, especially ‘friend of a friend’ stories. Women were not sure if the devices can be removed before their full 5- or 10-year duration of use, and felt that these timeframes did not fit with their reproductive intentions. Quantitative survey data showed that the most commonly endorsed concerns among never-users were painful fitting (55.8%), unpleasant removal of the device (60.1%), and concern about having a device ’inside me' (60.2%). Conclusions To facilitate fully informed contraceptive choice, information provided to women considering IUC should be tailored to more fully address the concerns expressed by never-users, particularly around the details of insertion and removal, and concerns about the adverse, long-term effects of the device. Women need to be reassured that IUC can be removed and fertility restored at any time following insertion

    Made corrections: a prison-based street art intervention for young offenders

    Get PDF
    This paper describes a prison-based street art intervention that took place at a Lithuanian institution for young offenders. During the first stage of the project, existing historical graffiti and murals on the prison walls were uncovered and documented. The second stage of the project involved working with the young offenders to co-produce a series of collaborative large-scale works within the prison walls, some of which incorporated elements of these earlier murals as a form of living heritage. The final stage of the project reproduced a selection of this work outside on the walls of the local city. Future work will involve a more formal evaluation of the impact of the intervention on the young offenders, the prison staff, and the local community

    The involvement of school nurses in the delivery of sexual healthcare: experiences and training

    Get PDF
    This paper reports a study of the involvement of school nurses, in one primary care trust (PCT) in England, in sex and relationships education and service provision. It explores the training they have received and their preferences for the format and content of future training. Seventeen of the nineteen nurses surveyed had direct involvement in the delivery of sexual healthcare or sex and relationship education to young people. Almost no education in sexual issues was reported in pre-registration training. Most had received post registration education or training in sexual health. School nurses favoured short workshops over longer credit bearing educational courses. Time constraints were identified as an obstacle to training. Social, ethical, legal and religious issues, gender inequality and sexual assault were areas in which a need for more training was identifie
