Sedentary behaviors and adiposity in young people: causality and conceptual model

Research on sedentary behavior and adiposity in youth dates back to the 1980s. Sedentary behaviors, usually screen time, can be associated with adiposity. Although the association usually is small but significant, the field is complex, and results are dependent on what sedentary behaviors are assessed and may be mediated and moderated by other behaviors

Using technologies in teaching : an initiative in academic staff development

Academic staff development in the pedagogical applications of new technologies is fundamental to the transformation of teaching and learning in tertiary education settings. We present a case study of a staff development activity at Deakin University, a multi-campus university offering on and off-campus programs, which aimed to develop a collegial online experience for academics interested in using online technologies. It is contextualised within a broadly based centrally funded project initiated by the University to extend the use of technologies in significant curriculum areas. The initiative employed a text-based, asynchronous computer conferencing environment. We describe the structure of the online environment and explore the major issues raised by the participants based on their experience and evaluation of the conference. We conclude by raising key questions that draw on our experience of the successful outcome of this initiative to advance relevant and meaningful opportunities for academic staff development.<br /

Bio-inspired pulmonary surfactant-modified nanogels : a promising siRNA delivery system

Inhalation therapy with small interfering RNA (siRNA) is a promising approach in the treatment of pulmonary disorders. However, clinical translation is severely limited by the lack of suitable delivery platforms. In this study, we aim to address this limitation by designing a novel bioinspired hybrid nanoparticle with a core-shell nanoarchitecture, consisting of a siRNA-loaded dextran nanogel (siNG) core and a pulmonary surfactant (Curosurf (R)) outer shell. The decoration of siNGs with a surfactant shell enhances the colloidal stability and prevents siRNA release in the presence of competing polyanions, which are abundantly present in biofluids. Additionally, the impact of the surfactant shell on the biological efficacy of the siNGs is determined in lung cancer cells. The presence of the surfactants substantially reduces the cellular uptake of siNGs. Remarkably, the lowered intracellular dose does not impede the gene silencing effect, suggesting a crucial role of the pulmonary surfactant in the intracellular processing of the nanoparticles. In order to surmount the observed reduction in cellular dose, folate is incorporated as a targeting ligand in the pulmonary surfactant shell to incite receptor-mediated endocytosis. The latter substantially enhances both cellular uptake and gene silencing potential, achieving efficient knockdown at siRNA concentrations in the low nanomolar range. (C) 2015 Elsevier B.V.

Enhancing health care non-technical skills: the TINSELS programme

Background and Context: Training in ‘non-technical skills’, social (communication and team work) and cognitive (analytical and personal behaviour) skills, in healthcare have been of great interest over the last decade. Whilst the majority of publications focus on ‘whether’ such education can be successful, they overlook the question of ‘how’ they enhance skills. We designed and piloted an original, theoretically robust and replicable teaching package that addresses non-technical skills in the context of medicines safety through simulation-based inter professional learning: the TINSELS (Training In Non-technical Skills to Enhance Levels of Medicines Safety) Programme. Innovation: A modified Delphi process was completed to identify learning outcomes, and recruitment of multi-professional teams was through local publicity. The faculty developed a three-session simulation based intervention: session one was a simulated ward encounter with multiple medicine related activities; session two was an extended debrief and facilitated discussion; and session three a ‘chamber of horrors’ where inter professional teams identified potential sources of error. Each session was completed in the simulation suite with 6 – 9 participants, lasted approximately 90m minutes, and took place over 2 weeks. Full details of the course will be presented to facilitate dissemination. Implications: Likert scale feedback was collected after the course (1 strongly disagree-5 strongly agree). Mean scores were all greater than 4, with qualitative feedback noting the fidelity of the authentic inter professional learner groups. A previously validated safety attitudes questionnaire found changes in attitudes towards handover of care and perceptions of safety levels in the workplace post intervention. An original, simulation based, multi-professional training programme has been developed with learning and assessment materials available for widespread replication

Developing career aspirations of information technology students at Deakin University

It is important for students to develop informed and realistic career aspirations to gain the most value from their university studies towards achieving their initial career goals. However developing students&rsquo; career aspirations, goals, and expectations is a complex and discipline-specific process. In Information Technology (IT) no clear career development framework is evident in the literature. Recent research in Australia argues that electronic portfolios are a useful way for students to develop, articulate and document career objectives to enhance their employability. IT students at Deakin engage in formal training and assessment with respect to developing their professional skills and career understandings. Currently electronic portfolios feature as a useful method for evidencing professional competencies for employability. Through a combined quantitative and qualitative analysis of 306 students&rsquo; articulated current career aspirations, qualitative analysis of 7 staff opinions of desired student career competencies, and a quantitative analysis of 28 students&rsquo; current work personality traits assessments (Work Personality Index), this work presents an analysis of the current state of IT students&rsquo; career development. The results indicate that while students reported short-term career aspirations, navigating to their long-term career goals is going to require addressing difficult barriers such as confidence (self-perception) and motivation. This research will influence a larger program-wide endeavour to build student career competencies for employability in IT at Deakin University

Understanding career aspirations of Information Technology students at Deakin University

Students need to develop informed and realistic career aspirations to gain the most from their university studies towards their initial career development. However developing their aspirations, goals, and expectations is a complex process. In Information Technology (IT) no clear career development framework is evident in the literature. We present a pilot study which investigates the career aspirations of novice students studying IT at an Australian University. Through a series of career activities their aspirations were explored with the aim of improving support for career development. Results indicate that students have no clear short- or long- term aspirations, yet believe that programming skills are key to achieve a career in IT

Free-Enterprise Farming on Grasslands in Central NSW, Australia

A pathway is described in developing and improving the pastures on family-owned sheep and beef properties at sites near Blayney in central NSW. Initially, the twin approach of sowing perennial grasses, predominantly phalaris (Phalaris aquatica) with subterranean clover (Trifolium subterraneum) plus the recommended addition of superphosphate fertiliser, was closely followed but within a decade ill-thrift in pastures and livestock occurred. Once the core problem of soil acidity was recognised, steps were taken to overcome this constraint with applications of lime. However, an additional modification involving the application of gypsum with lime had to be sorted out and applied. This approach is explained. While recent drought conditions on the Central Tablelands/Slopes have been a factor in reducing the productivity of district pastures, an important part of the problem is a consequence of many landowners not understanding the basic principles of plant and livestock nutrition, an unwillingness of some research/advisory agronomists to recognise the expertise of successful producers, and the implementation of various farmer subsidy and support schemes that appear to reward dependent producers rather than encouraging independence

Family influences on children's physical activity and fruit and vegetable consumption

Background : There is evidence of a clustering of healthy dietary patterns and physical activity among young people and also of unhealthy behaviours. The identification of influences on children\u27s health behaviors, particularly clustered health behaviors, at the time at which they develop is imperative for the design of interventions. This study examines associations between parental modelling and support and children\u27s physical activity (PA) and consumption of fruit and vegetables (FV), and combinations of these behaviours.Methods : In 2002/3 parents of 775 Australian children aged 10&ndash;12 years reported how frequently their child ate a variety of fruits and vegetables in the last week. Children wore accelerometers for eight days during waking hours. Parental modelling and parental support (financial and transport) were self-reported. Binary logistic and multinomial logistic regression analyses examined the likelihood of achieving &ge; 2 hours of PA per day (high PA) and of consuming &ge; 5 portions of FV per day (high FV) and combinations of these behaviors (e.g. high PA/low FV), according to parental modelling and support.Results : Items of parental modelling and support were differentially associated with child behaviours. For example, girls whose parents reported high PA modelling had higher odds of consuming &ge; 5 portions of FV/day (OR = 1.95, 95% CI = 1.32&ndash;2.87, p &lt; 0.001). Boys whose parents reported high financial support for snacks/fast foods had higher odds of having \u27high PA/low FV\u27 (OR = 2.0, 95% CI = 1.1&ndash;3.7).Conclusion : Parental modelling of and support for physical activity and fruit and vegetable consumption were differentially associated with these behaviours in children across behavioural domains and with combinations of these behaviours. Promoting parents\u27 own healthy eating and physical activity behaviours as well encouraging parental modelling and support of these behaviours in their children may be important strategies to test in future research.<br /
