    © 2018 Australasian Journal of Educational Technology. Quality teaching is a strategic objective for universities; thus, there is an expectation that university teachers design high quality learning experience for their students. The field of learning design has developed over the past 15 years as a way to support teachers in their design work. There has been significant research and development work that has focused on creating support tools to help teachers plan, develop and deliver learning experiences. However, little is known about what supports teachers access and use when they design and overall how teachers undertake their design work. This paper presents the findings from a qualitative study that investigated the types of supports 30 teachers from 16 Australian universities reported using in their design work. Data was collected from semi-structured interviews, and the results show that participants accessed a variety of supports depending on their design need. The kind of support participants accessed in their design work were colleagues, literature, workshops and seminars, conferences, institutional support services, and enrolment in postgraduate study. How participants explained using these supports can be characterised as varied, personalised, dynamic and networked. Based on these results, implications for the learning design field are discussed with recommendations for future research

    Social capital from online discussion forums: Differences between online and blended modes of delivery

    © 2015. This study explored the concept of social capital in higher education contexts by investigating student discussion forum activity and academic performance. To address these aims online discussion forum logs, student marks and teaching delivery method (blended or fully online) data were extracted from the universities learning management system (LMS). Student social network centrality measures were then calculated from the course discussion activity and correlated against student academic performance for each delivery mode. Drawing on social capital and social network theories the analyses identified that in comparison to low performing students the high-performing group held more central positions in their networks and tended to establish dense social connections with students of a similar academic ability. It was also observed that the relationships formed in blended teaching units were of a greater intensity and reciprocity than those established in fully online teaching units indicating a higher level of social capital was reached. This difference in the amount of available social capital between the two teaching modes suggests that students in blended units have comparatively greater access to resources embedded within the network, which in turn can be mobilised to assist them in their academic endeavours

    Isolation and characterization of the full-length cDNA encoding a member of a novel cytochrome p450 family (CYP320A1) from the tropical freshwater snail, Biomphalaria glabrata, intermediate host for Schistosoma mansoni

    Cytochrome p450s (cyp450s) are a family of structurally related proteins, with diverse functions, including steroid synthesis and breakdown of toxins. This paper reports the full-length sequence of a novel cyp450 gene, the first to be isolated from the tropical freshwater snail Biomphalaria glabrata, an important intermediate host of Schistosoma mansoni. The nucleotide sequence is 2291 bp with a predicted amino acid sequence of 584aa. The sequence demonstrates conserved cyp450 structural motifs, but is sufficiently different from previously reported cyp450 sequences to be given a new classification, CYP320A1. Initially identified as down-regulated in partially resistant snails in response to S. mansoni infection, amplification of this gene using RT-PCR in both totally resistant or susceptible snail lines when exposed to infection, and all tissues examined, suggests ubiquitous expression. Characterization of the first cyp450 from B. glabrata is significant in understanding the evolution of these metabolically important proteins

    From Comedy Targets to Comedy-Makers: Disability and Comedy in Live Performance

    Get PDF
    The stand-up comedy landscape has been transformed in recent years with an increased number of disabled comedians performing. Via semi-structured interviews with disabled comedians, this article provides a thematic analysis of the material and ideological motives, intentions and lived experiences of disabled comedians. Two themes are discussed - comedy management and control; and affirming disability through comedy. These themes are characterised by complexity and contradictions. The article concludes that, although not a straightforward process, stand-up comedy enacted by disabled comedians is potentially a powerful tool through which hegemonic norms around disability can be challenged and renegotiated

    Stretched exponential relaxation in the mode-coupling theory for the Kardar-Parisi-Zhang equation

    Full text link
    We study the mode-coupling theory for the Kardar-Parisi-Zhang equation in the strong-coupling regime, focusing on the long time properties. By a saddle point analysis of the mode-coupling equations, we derive exact results for the correlation function in the long time limit - a limit which is hard to study using simulations. The correlation function at wavevector k in dimension d is found to behave asymptotically at time t as C(k,t)\simeq 1/k^{d+4-2z} (Btk^z)^{\gamma/z} e^{-(Btk^z)^{1/z}}, with \gamma=(d-1)/2, A a determined constant and B a scale factor.Comment: RevTex, 4 pages, 1 figur

    A comparison of systems for measuring methane emissions from sheep

    Get PDF
    Two experiments were conducted, at ADAS Drayton in the autumn and winter 1996/1997, to compare methane (CH4) emissions from sheep housed either in a polytunnel system or in open-circuit respiration chambers. In each system, the sheep received maintenance levels of either cut grass or high temperature dried grass pellets (HTDG). All experiments in the tunnel were conducted on concrete to avoid any interactions of the CH4 with the soil/plant environment. The results suggested that CH4 production from the open-circuit chambers was greater than from the tunnel system (26·9±0·46 v. 31·7±0·35 l/kg dry matter intake (±S.E.) for open circuit respiration chambers and tunnel, respectively). Recovery tests gave similar results for both systems (95·5–97·9% for tunnels and 89·2–96·7% for chambers), and confirmed that both methods give good quantitative recovery of added CH4, and can therefore be assumed to provide reliable estimates of emissions from animals. There is no technical explanation, therefore, for the different estimates of emissions provided by the two systems. Further studies are required to understand the reasons for the differences and in particular, the possible links between animal behaviour induced by the two systems and CH4 emission rates
