Engaging Indigenous students through school-based health education

This resource sheet focuses on the delivery of school-based health education for Indigenous students in Australian schools and the effective strategies that support positive health outcomes for Indigenous students

Towards an understanding of fidelity within the context of school-based health education

Schools and schooling have long provided a tempting site for the delivery of public health strategies that address and promote young people's current and future health. However, an emerging concern regarding the mobilisation of public health interventions within school settings has been the failure of school teachers to deliver such programs with fidelity. For educators, these notions of fidelity stand in stark contrast to the tenets of student-centred teaching. In seeking to explore these tensions further, this paper draws upon a collaborative health education project conducted with schools and teachers from Queensland, Australia. Findings from this project reveal the complexity associated with curriculum implementation in school settings, where diverse resources including timetable allocations and teacher expertise mitigate the achievement of program fidelity. In our efforts to explain the findings emerging from this project, we have drawn on the conceptual reference points of Basil Bernstein's theory of the pedagogic device to reveal the predictable misalignment of the health and education sectors' expected outcomes of school-based health initiatives. In conclusion, we argue that our exploration of issues pertaining to fidelity demonstrates the need for health and education sectors alike to conduct their work according to a clear articulation of the realistic, educative role that schools can play in promoting healthy living

The earth sciences in the scientific letters of Giovanni Capellini

Giovanni Capellini (1833-1922) was one of the leading representatives of the Italian and international scientific community from the mid-19th century until 1922, the year of his death. Professor of Geology at the University of Bologna from 1860, geologist, palaeontologist and archaeologist, in 1871 he organised, straight after the unification of Italy, the 5th International Congress in Archaeology and Prehistoric Anthropology, first in Italy, and in 1881 brought to Bologna, for the first time ever in Italy, the 2nd International Geological Congress. His studies and publications strongly influenced the geological thinking of his times. At the Archiginnasio Library in Bologna there are as many as 30,000 documents from his scientific letters (The Capellini Archive), the result of an intense correspondence he had with geologists, seismologists, astronomers and meteorologists, but also with people from the world of culture and politics. The letters relating to the earth sciences, from scientific but also political point of view, are the majority. The archive includes letters from more then 4,300 senders, of which at least 25% foreign ones incuding Charles Lyell (geologist), Emmanuel Friedlaender (volcanologist), Philip Eduard De Verneuil (naturalist), Henry James Johnston Lavis (volcanologist)

Substitution Program in Indonesia and Australia as Health Promotion Model at Schools

Obesity has been increasing as much as twice on age 6-12 years. The increase is happening both in Indonesia and Australia. The objective of this research is to construct a program model in Australia that can be substituted to be a health promotion model at School in effort to suppress child obesity. Research was conducted in 2014 with qualitative approach. Instruments used are as follow 1) Secondary data filling form 2) In depth interview guidence instrument 3) FGD (Focus Group Discussion) and BST (Brain Storming Technique). The informations were obtained by purposive and snowball technique. Data analysis by Miles and Huberman model. Substitution model is based on consideration that applied model has potential to be developed and other models whether internal or external ones in Indonesia. The model will be substituted by considering school condition and situation. School Health Unit (SKU) is a potential platform to promote health by these activities 1) Formal health education as taken place curricullum 2) Informal health education in forms of (1) health education information (2) Self health behaviour monitoring and control (3) Health promotion by doing healthy life (4) distribution of health education booklet to teachers and parents

Gold remobilisation and formation of high grade ore shoots driven by dissolution-reprecipitation replacement and Ni substitution into auriferous arsenopyrite

Both gold-rich sulphides and ultra-high grade native gold oreshoots are common but poorly understood phenomenon in orogenic-type mineral systems, partly because fluids in these systems are considered to have relatively low gold solubilities and are unlikely to generate high gold concentrations. The world-class Obuasi gold deposit, Ghana, has gold-rich arsenopyrite spatially associated with quartz veins, which have extremely high, localised concentrations of native gold, contained in microcrack networks within the quartz veins where they are folded. Here, we examine selected samples from Obuasi using a novel combination of quantitative electron backscatter diffraction analysis, ion microprobe imaging, synchrotron XFM mapping and geochemical modelling to investigate the origin of the unusually high gold concentrations. The auriferous arsenopyrites are shown to have undergone partial replacement (~15%) by Au-poor, nickeliferous arsenopyrite, during localised crystal-plastic deformation, intragranular microfracture and metamorphism (340-460 °C, 2 kbars). Our results show the dominant replacement mechanism was pseudomorphic dissolution-reprecipitation, driven by small volumes of an infiltrating fluid that had relatively low fS2 and carried aqueous NiCl2. We find that arsenopyrite replacement produced strong chemical gradients at crystal-fluid interfaces due to an increase in fS2 during reaction, which enabled efficient removal of gold to the fluid phase and development of anomalously gold-rich fluid (potentially 10 ppm or more depending on sulphur concentration). This process was facilitated by precipitation of ankerite, which removed CO2 from the fluid, increasing the relative proportion of sulphur for gold complexation and inhibited additional quartz precipitation. Gold re-precipitation occurred over distances of 10 µm to several tens of metres and was likely a result of sulphur activity reduction through precipitation of pyrite and other sulphides. We suggest this late remobilisation process may be relatively common in orogenic belts containing abundant mafic/ultramafic rocks, which act as a source of Ni and Co scavenged by chloride-bearing fluids. Both the preference of the arsenopyrite crystal structure for Ni and Co, rather than gold, and the release of sulphur during reaction, can drive gold remobilisation in many deposits across broad regions

Primary schools and the delivery of relationships and sexuality education: the experience of Queensland teachers

Primary school provides an appropriate opportunity for children to commence comprehensive relationships and sexuality education (RSE), yet many primary school teachers avoid teaching this subject area. In the absence of teacher confidence and competence, schools have often relied on health promotion professionals, external agencies and/or one-off issue related presentations rather than cohesive, systematic and meaningful health education. This study examines the implementation of a ten-lesson pilot RSE unit of work and accompanying assessment task in two primary schools in South-East Queensland, Australia. Drawing predominantly from qualitative data, this research explores the experiences of primary school teachers as they engage with RSE curriculum resources and content delivery. The results show that the provision of a high quality RSE curriculum resource grounded in contemporary educational principles and practices enables teachers to feel more confident to deliver RSE and minimises potential barriers such as parental objections and fear of mishandling sensitive content
