First year Bachelor of Education students' mental models of themselves as learners

There is political and academic concern about the high retention rate occurring among first year education students in universities worldwide. It is believed that students’ knowledge and thinking skills may prevent them from completing their teacher education program. Mental models are seen as a crucial factor since research shows that they can profoundly influence students’ knowledge, critical thinking skills, and problem solving in learning environments. Accessing students’ mental models will provide information about their conceptual scaffolds. By exploring students’ mental models, lecturers may be able to identify students’ difficulties and develop better instructional designs. This paper presents findings from a research project that examined First year Bachelor of Education students’ mental models while undertaking a pre-service teaching subject in Information and Communication Technologies and Education. The quantitative method study is used to capture the breadth, depth, and correlation factors of students’ mental models. Analysis was carried using exploratory factor analysis. Results suggest that there are four factor presenting mental models of the students: Academic Engagement with Effective Learning Strategy Mental Model, Disengagement Mental Model, Collaboration Mental Model, and Ineffective Learning Strategy Mental Model

Workforce Development in the South West Voluntary and Community Sectors:Skill Shortages Study

The Voluntary Sector National Training Organisation, now the National  Workforce Development Hub, describes the Voluntary and Community  Sector  as  diverse  and  covering  a  variety  of  different  organisations.  Organisations range from traditional charities, to companies that trade to  support their social aims, through to informal community organisations.  The sector also includes federations, or networks of local groups working  under national umbrellas.  Voluntary and community sector organisations  provide  a  wide  range  of  services  and  activities  and  many  of  the  organisations are involved in the delivery of learning, whether through  accredited training or informal learning.  The Government has increasingly recognised the importance of Voluntary  and  community  sector  organisations  and  the  key  role  that  they  play  nationally,  regionally  and  locally.    Initiatives  to  support  the  sector,  underpinned by funding, have been undertaken and the Government has  been  active  in  encouraging  and  commissioning  research  and  strategic  planning  in  the  sector,  in  particular  emphasising  the  importance  of  developing the skills, capacities and potential of the workforce.  Sector organisations generally display a strong commitment to training  and workforce development.  However, in spite of this commitment and  the presence of a high proportion of well‐qualified workers, skills gaps,  that is skills lacking in the current workforce, and skills shortages caused  by recruitment difficulties, are present in the sector.  There are also skills  gaps and shortages in the volunteer workforce

Grandparents battle to be key stakeholders in protecting grandchildren

Introduction: Grandparents are increasingly involved in the care of grandchildren, including after child protection intervention. Method: A recent Australian qualitative research partnership explored how relationships between grandparents and their grandchildren could be optimised after child safety concerns. Interviews and focus groups were undertaken with 77 participants, including 51 grandparents, 12 parents, six foster carers and eight child and family workers. Emerging themes reported here focus on the role of grandparents and their perceptions of, and interactions with, the child protection system. Findings: Overall, findings identify that grandparents wanted to help safeguard their grandchildren but many encountered an adversarial child protection system that left them feeling powerless, fearful and unimportant. Aboriginal participants reiterated that child protection workers needed to better understand how maintaining kinship networks provided a protective factor for Aboriginal children, and that grandparents were key stakeholders in their grandchildren’s lives. Implications: The findings from this study affirm the value and role of grandparents and highlight the need for implemented family-inclusive child protection practice within and beyond the Australian context

Comparing alternating pressure mattresses and high-specification foam mattresses to prevent pressure ulcers in high-risk patients: the PRESSURE 2 RCT

Background: Pressure ulcers (PUs) are a burden to patients, carers and health-care providers. Specialist mattresses minimise the intensity and duration of pressure on vulnerable skin sites in at-risk patients. Primary objective: Time to developing a new PU of category ≥ 2 in patients using an alternating pressure mattress (APM) compared with a high-specification foam mattress (HSFM). Design: A multicentre, Phase III, open, prospective, planned as an adaptive double-triangular group sequential, parallel-group, randomised controlled trial with an a priori sample size of 2954 participants. Randomisation used minimisation (incorporating a random element). Setting: The trial was set in 42 secondary and community inpatient facilities in the UK. Participants: Adult inpatients with evidence of acute illness and at a high risk of PU development. Interventions and follow-up: APM or HSFM – the treatment phase lasted a maximum of 60 days; the final 30 days were post-treatment follow-up. Main outcome measures: Time to event. Results: From August 2013 to November 2016, 2029 participants were randomised to receive either APM (n = 1016) or HSFM (n = 1013). Primary end point – 30-day final follow-up: of the 2029 participants in the intention-to-treat population, 160 (7.9%) developed a new PU of category ≥ 2. There was insufficient evidence of a difference between groups for time to new PU of category ≥ 2 [Fine and Gray model HR 0.76, 95% confidence interval (CI) 0.56 to 1.04; exact p-value of 0.0890 and 2% absolute difference]. Treatment phase sensitivity analysis: 132 (6.5%) participants developed a new PU of category ≥ 2 between randomisation and end of treatment phase. There was a statistically significant difference in the treatment phase time-to-event sensitivity analysis (Fine and Gray model HR 0.66, 95% CI 0.46 to 0.93; p = 0.0176 and 2.6% absolute difference). Secondary end points – 30-day final follow-up: new PUs of category ≥ 1 developed in 350 (17.2%) participants, with no evidence of a difference between mattress groups in time to PU development, (Fine and Gray model HR 0.83, 95% CI 0.67 to 1.02; p-value = 0.0733 and absolute difference 3.1%). New PUs of category ≥ 3 developed in 32 (1.6%) participants with insufficient evidence of a difference between mattress groups in time to PU development (Fine and Gray model HR 0.81, 95% CI 0.40 to 1.62; p = 0.5530 and absolute difference 0.4%). Of the 145 pre-existing PUs of category 2, 89 (61.4%) healed – there was insufficient evidence of a difference in time to healing (Fine and Gray model HR 1.12, 95% CI 0.74 to 1.68; p = 0.6122 and absolute difference 2.9%). Health economics – the within-trial and long-term analysis showed APM to be cost-effective compared with HSFM; however, the difference in costs models are small and the quality-adjusted life-year gains are very small. There were no safety concerns. Blinded photography substudy – the reliability of central blinded review compared with clinical assessment for PUs of category ≥ 2 was ‘very good’ (kappa statistic 0.82, prevalence- and bias-adjusted kappa 0.82). Quality-of-life substudy – the Pressure Ulcer Quality of Life – Prevention (PU-QoL-P) instrument meets the established criteria for reliability, construct validity and responsiveness. Limitations: A lower than anticipated event rate. Conclusions: In acutely ill inpatients who are bedfast/chairfast and/or have a category 1 PU and/or localised skin pain, APMs confer a small treatment phase benefit that is diminished over time. Overall, the APM patient compliance, very low PU incidence rate observed and small differences between mattresses indicate the need for improved indicators for targeting of APMs and individualised decision-making. Decisions should take into account skin status, patient preferences (movement ability and rehabilitation needs) and the presence of factors that may be potentially modifiable through APM allocation, including being completely immobile, having nutritional deficits, lacking capacity and/or having altered skin/category 1 PU. Future work: Explore the relationship between mental capacity, levels of independent movement, repositioning and PU development. Explore ‘what works for whom and in what circumstances’.

Baseline Comorbidities in a Population-Based Cohort of Rheumatoid Arthritis Patients Receiving Biological Therapy: Data from the Australian Rheumatology Association Database

Aims. To describe the baseline characteristics of an Australian population-based cohort of rheumatoid arthritis (RA) patients commencing biological therapy. Methods. Descriptive analysis from the Australian Rheumatology Association Database (ARAD). Results. Up to October 2006, there were 681 RA patients taking biologics enrolled in ARAD. Baseline data were available for 624 (72% female, mean (SD) age 57.0 (12.5) years). Of these, 59.5% reported at least one comorbid condition, most commonly hypertension (35.7%) and osteoporosis (30.4%); 61 (9.8%) had a history of malignancy (35 nonmelanoma skin, 5 breast, 4 bowel, 5 cervix, 3 melanoma, 3 prostate and 1 each of lip, lung, myeloma, testis, uterus, vagina). Self-reported infections within the previous 6 months were common (71.5%). Conclusions. History of comorbidities, including recent infections, is common among Australian RA patients commencing biologics, and 10% have a history of malignancy. This may impact future evaluations of health outcomes among this population, including attribution of adverse events of biologic therapy

Long-term annual and monthly changes in mysids and caridean decapods in a macrotidal estuarine environment in relation to climate change and pollution

© 2018 Elsevier B.V. A 26-year time series of monthly samples from the water intake of a power station has been used to analyse the trends exhibited by number of species, total abundance, and composition of the mysids and caridean decapods in the inner Bristol Channel. During this period, annual water temperatures, salinities and the North Atlantic Oscillation Index (NAOI) in winter did not change significantly, whereas annual NAOI declined. Annual mean monthly values for the number of species and total abundance both increased over the 26 years, but these changes were not correlated with any of the measured physico-chemical/climatic factors. As previous studies demonstrated that, during a similar period, metal concentrations in the Severn Estuary and Bristol Channel (into which that estuary discharges) declined and water quality increased, it is proposed that the above changes are due to an improved environment. The fauna was dominated by the mysids Mesopodopsis slabberi and Schistomysis spiritus, which collectively contributed 94% to total abundance. Both species, which were represented by juveniles, males, non-brooding females and brooding females, underwent statistically-indistinguishable patterns of change in abundance over the 26 years. When analysis was based on the abundances of the various species, the overall species composition differed significantly among years and changed serially with year. When abundances were converted to percentage compositions, this pattern of seriation broke down, demonstrating that changes in abundance and not percentage composition were responsible for the seriation. As with the number and abundance of species, changes in composition over the 26 years were not related to any of the physico-chemical/climatic factors tested. Species composition changed monthly in a pronounced cyclical manner throughout the year, due to statistically different time-staggered changes in the abundance of each species. This cyclicity was related most strongly to salinity

Removing Orbital Debris with Lasers

Orbital debris in low Earth orbit (LEO) are now sufficiently dense that the use of LEO space is threatened by runaway collisional cascading. A problem predicted more than thirty years ago, the threat from debris larger than about 1 cm demands serious attention. A promising proposed solution uses a high power pulsed laser system on the Earth to make plasma jets on the objects, slowing them slightly, and causing them to re-enter and burn up in the atmosphere. In this paper, we reassess this approach in light of recent advances in low-cost, light-weight modular design for large mirrors, calculations of laser-induced orbit changes and in design of repetitive, multi-kilojoule lasers, that build on inertial fusion research. These advances now suggest that laser orbital debris removal (LODR) is the most cost-effective way to mitigate the debris problem. No other solutions have been proposed that address the whole problem of large and small debris. A LODR system will have multiple uses beyond debris removal. International cooperation will be essential for building and operating such a system.Comment: 37 pages, 15 figures, in preparation for submission to Advances in Space Researc
