    Non-selection as a factor contributing to retirement from Australian sport

    Get PDF
    Retirement from sport is inevitable and will occur at some stage in every athlete\u27s career. Retirement may be voluntary or involuntary and signifies a lifestyle change that may be a major impact for many athletes. Involuntary retirement may occur in relation to chronological ageing, injury or non-selection. This study undertook an in-depth examination of one type of involuntary exit from sport, that of non-selection. The purpose of this study was to explore, in-depth, the reactions and experiences of Australian athletes who were subject to non-selection from their sport. Supporting this main investigation were three sub questions which focused on factors that were problematic for the athletes, factors non-problematic for athletes and athlete recommendations to assist sporting organisations, administrators, coaches, selectors, significant others, and other athletes in dealing with non-selection from Australian sport. Two semi-structured interviews with open-ended questions were conducted with seven female and eight male state and national athletes. Athletes were current or former representatives in the three team sports of field hockey, cricket and water polo and were resident in Western Australia. Inductive content analysis of verbatim transcripts was used to establish categories of patterns or themes portraying the athletes\u27 experiences of non-selection. The major theme to emerge was the lack of understanding and knowledge of the issues of non-selection and the subsequent impact on athletes. This lack of understanding was not limited to any one individual but encompassed sporting and non-sporting individuals such as the sporting officials and the athlete\u27s family members. Athletes also perceived a strong political influence in relation to their non-selection. Although non-selection was initially a difficult time for many athletes in this study their enjoyment and fulfilment from sport saw the majority continue as participants at a lower level within the same sport

    EVLA Observations of OH Masers in ON 1

    Full text link
    This Letter reports on initial Expanded Very Large Array (EVLA) observations of the 6035 MHz masers in ON 1. The EVLA data are of good quality, lending confidence in the new receiver system. Nineteen maser features, including six Zeeman pairs, are detected. The overall distribution of 6035 MHz OH masers is similar to that of the 1665 MHz OH masers. The spatial resolution is sufficient to unambiguously determine that the magnetic field is strong (~ -10 mG) at the location of the blueshifted masers in the north, consistent with Zeeman splitting detected in 13441 MHz OH masers in the same velocity range. Left and right circularly polarized ground-state features dominate in different regions in the north of the source, which may be due to a combination of magnetic field and velocity gradients. The combined distribution of all OH masers toward the south is suggestive of a shock structure of the sort previously seen in W3(OH).Comment: 4 pages using emulateapj.cls including 2 tables and 2 color figure

    A feasibility analysis of the employment of satellite imagery to monitor and inspect surface mining operations in western Kentucky, volume 1

    Get PDF
    The author has identified the following significant results. Surface mining violation estimates were scaled by scores assigned by ten inspectors from western Kentucky to each violation. A sensitivity analysis was made by varying the violation costs; costs were varied by using three different average durations. These durations were: (1) best estimated duration; (2) longest possible duration as restricted by the one year permit renewal and bond release regulations, and (3) shortest possible duration when inspections were made. If a social cost cannot be reduced, then the value of the social cost is irrelevant. Indications from the increased inspection rate of 1975 were that the total amount of fines collected per year remains constant independent of the increased detection rate

    The Effect of Oral and Intraperitoneal Administration of Alcohol upon the Concentration of Alcohol in the Blood of the Rat

    A number of experiments were made in this laboratory to determine the rate of absorption of alcohol into the blood of rats after the administration of alcohol both orally and by intraperitoneal injection. Both fasted and unfasted rats were used in these experiments

    The Impact of Spatial Heterogeneity in Land Use Practices and Aquifer Characteristics on Groundwater Conservation Policy Cost

    Get PDF
    Estimation of agricultural policy cost for a given level of groundwater conservation requires the establishment of an accurate baseline condition. This is especially critical when the benefits and cost of any conservation program are generally estimated relative to the status quo policy or baseline situation. An inaccurate baseline estimate will lead to poor estimates of potential water conservation savings and agricultural policy cost. Over a 60-year planning horizon per acre net present value is as much as 29.8% higher for a study area when aquifer characteristics are assumed to be homogenous and set to their average area value than when the heterogeneity in aquifer characteristics is explicitly modeled.Aquifer Modeling, Economics, Resource /Energy Economics and Policy,
