    Flu Shots, Mammograms, and the Perception of Probabilities

    We study individuals' decisions to decline or accept preventive health care interventions such as flu shots and mammograms. In particular, we analyze the role of perceptions of the effectiveness of the intervention, by eliciting individuals' subjective probabilities of sickness and survival, with and without the interventions. Respondents appear to be aware of some of the qualitative relationships between risk factors and probabilities. However, on average they have very poor perceptions of the absolute probability levels as reported in the epidemiological literature. Perceptions are less accurate if a respondent is female and has no college degree. Perceived probabilities significantly affect the subsequent take-up rate of flu shots and mammograms.preventive health care, probability perceptions

    Bioavailability of soil organic carbon and Fe as influenced by forestry practices in a subtropical coastal catchment

    Potential impacts of plantation forestry practices on soil organic carbon and Fe available to microorganisms were investigated in a subtropical coastal catchment. The impacts of harvesting or replanting were largely limited to the soil top layer (0–10 cm depth). The thirty-year-old Pinus plantation showed low soil moisture content (Wc) and relatively high levels of soil total organic carbon (TOC). Harvesting and replanting increased soil Wc but reduced TOC levels. Mean dissolved organic carbon (DOC) and microbial biomass carbon (MBC) increased in harvested or replanted soils, but such changes were not statistically significant (P > 0.05). Total dithionite-citrate and aqua regia-extractable Fe did not respond to forestry practices, but acid ammonium oxalate and pyrophosphate-extractable, bioavailable Fe decreased markedly after harvesting or replanting. Numbers of heterotrophic bacteria were significantly correlated with DOC levels (P < 0.05), whereas Fe-reducing bacteria and S-bacteria detected using laboratory cultivation techniques did not show strong correlation with either soil DOC or Fe content

    Food Acceptability, Menu Fatigue, and Aversion on ISS Missions

    Get PDF
    The acceptability of the spaceflight food system has been linked to caloric intake and associated nutritional benefits. The diets of the United States Operating Segment crewmembers during a mission are restricted to 200 processed and prepackaged standard menu items supplemented with personal preference foods. ISS crew members have noted in debriefs that they would prefer more food variety for the length of the missions and they tire of certain foods over six months. It is possible that menu fatigue leads to decreases in acceptability and increased aversion to available foods, potentially contributing to the body mass loss often experienced by ISS crew. However, the impact of repeat food consumption on acceptability within the current spaceflight food system has not yet been systematically investigated. Limited variety and crew preferences within food categories may have more severe physical and behavioral health and performance consequences as mission duration increases. Characterizing the relationship between food acceptability and mission duration will contribute to defining requirements for an acceptable food system that will support crew health and performance on long duration missions

    Motivations, expectations and experiences of Australian rural and regional planners

    Get PDF
    Despite playing an extremely important role in shaping communities, the role and contribution of planners is not widely understood or acknowledged. At the same time, there is a shortage of planners in Australia, especially in non-urban areas. Thus, though an online survey of 185 rural and regional planners, this research explores their motivations, expectations and experiences. Most enjoyed and felt confident in their role, explaining that they valued the relaxed family orientated rural lifestyle and the varied nature of the planning work. Although they sometimes felt isolated, the non-urban location provided quicker progression to senior roles, the ability to engage directly with the community and to see the consequences of their decisions. Only half felt their education had prepared them well for their role, citing gaps in terms of computerised modelling, team leadership and conflict resolution skills. Their feedback centred on providing a more practical course, focussing more on regional planning, and encouraging urban and rural experience placements. As the first study to quantifiably explore rural and regional Australian planners perceptions of their role and challenges, the findings illustrate current experiences, key planning challenges, perceived educational gaps and future priorities

    Nitrous oxide emissions from irrigated cotton soils of northern Australia

    An automated gas sampling methodology has been used to estimate nitrous oxide (N2O) emissions from heavy black clay soil in northern Australia where split applications of urea were applied to furrow irrigated cotton. Nitrous oxide emissions from the beds were 643 g N/ha over the 188 day measurement period (after planting), whilst the N2O emissions from the furrows were significantly higher at 967 g N/ha. The DNDC model was used to develop a full season simulation of N2O and N2 emissions. Seasonal N2O emissions were equivalent to 0.83% of applied N, with total gaseous N losses (excluding NH3) estimated to be 16% of the applied N

    Client-centred Case Management: How Much Makes a Difference to Outcomes for Homeless Jobseekers?

    Get PDF
    Case management has become the predominant model for attempting to improve outcomes for young adults experiencing both homelessness and unemployment. However, there is little evidence-based knowledge about how young adults respond to case management, and how much intervention is needed to be effective. This Australian study utilised quantitative government data to investigate the effects of the amount of case management on key outcomes. With a purposive sample of 224 people aged 18-35, this study compared four different amounts of YP4 case management service received over a three-year period. Participants were categorised into four groupings depending on the number of case management contacts they received: 0-5, 6-20, 21-40, and 41-156. The findings show some significant group variations over the course of the trial in the areas of employment and accommodation. Participants who received 20 or more contacts had significantly better accommodation and employment outcomes than those who received fewer contacts

    A Health Systems Policy Framework on “How to” Build Cross-Sector Collaboration: Perspectives From Health Administrators and Leaders

    There are many barriers/challenges bringing multiple stakeholders within health and non-health together to collaborate to address population health. This study aims to identify the key components to build successful cross-sector collaboration and develop a policy framework for health systems integration and transformation. We conducted quantitative surveys and qualitative interviews with health administrators and leaders who volunteered to participate on six newly established teams or “Tables” to improve population health locally in Ontario, Canada. Using thematic analysis and methodological triangulation, we identified emergent themes that were confirmed by member checking. The Relational Coordination survey response rate was 62% (n=45). The survey results were correlated with the twelve interviews and member checking. Drawing from the perspectives of the health administrators and leaders of the “Tables”, the emergent themes identified for successful cross-sector collaboration were: 1) systems change mindset, 2) inter-dependency, 3) inter-organizational relationships, and 4) self-organizing capacity. A health systems policy framework on “how to” build cross-sector collaboration was developed to support and achieve health systems integration
