Vigiliae Christianae, Supplements, Volume: 150In this paper I want to take you on a walk through a garden. It is, to be sure, an imaginary garden; nevertheless, it bears a significance which extends beyond itself. Some of this significance concerns words and texts: for as we shall see, the garden is, amongst other things, a ‘garden of rhetoric’. The garden in question appears in the Gregory of Nyssa’s Homilies on the Song of Songs.[...
Going live : building academic capacity in blended learning using web-conferencing technologies
No full textThis paper reports on a current initiative at Queensland University of Technology to provide timely, flexible and sustainable training and support to academic staff in blended learning and associated techno-pedagogies via a web-conferencing classroom and collaboration tool, Elluminate Live!. This technology was first introduced to QUT in 2008 as part of the university‘s ongoing commitment to meeting the learning needs of diverse student cohorts. The centralised Learning Design team, in collaboration with the university‘s department of eLearning Services, was given the task of providing training and support to academic staff in the effective use of the technology for teaching and learning, as part of the team‘s ongoing brief to support and enhance the provision of blended learning throughout the university. The resulting program, ―Learning Design Live‖ (LDL) is informed by Rogers‘ theory of innovation and diffusion (2003) and structured according to Wilson‘s framework for faculty development (2007). This paper discusses the program‘s design and structure, considers the program‘s impact on academic capacity in blended learning within the institution, and reflects on future directions for the program and emerging insights into blended learning and participant engagement for both staff and students
Traversing the Boundaries and Borders Experienced by Learning Communities Within Online Problem Based Learning.
No full textThe ‘insider/outsider’ dilemma of ethnography: Working with young children and their families in cross-cultural contexts
No full textIn this article we unravel the difficulty of being researchers in the homes and classrooms of children and
their families whose origins are, for one of us, very different and, for the other, very similar to our own.
We first situate our work within theories of early socialization and literacy teaching which underpin our
understanding of how young children in cross-cultural contexts learn. We then turn to the question of
working with the families and teachers of these children which poses dilemmas not explained by the theories
presented. We illustrate these through a series of vignettes typifying both the ‘Outsider’ and the ‘Insider’ role.
The stories highlight paradigmatic moments of complexity, clashes or collusion which we unpick in terms of
their generalizability for others working in the field. Finally, we extend theories of dialogue in our search for
a methodology for collaborative work in future cross-cultural ethnographic studies

Nitrogen metabolism in Mycobacterium smegmatis
No full textNitrogen is an essential component of the bacterial cell and bacteria have developed elaborate regulatory mechanisms used to control the uptake, assimilation and metabolism of nitrogen. In this thesis, I have developed a nitrogen-limited continuous culture system to gain further insights into nitrogen metabolism in mycobacteria and their response to nitrogen limitation. I identified 357 differentially expressed genes in response to nitrogen limitation in continuous culture, including changes in amino acid metabolic pathways. I found 26 transcriptional regulators that mediated the global transcriptomic response of Mycobacterium smegmatis to nitrogen limitation and I identified several non-coding RNAs that might be involved in the regulation of nitrogen- regulated gene expression. Subsequently, I characterised two differentially expressed transcriptional regulators, AmtR (MSMEG_4300) and CadC (MSMEG_3297) using a combination of genome-wide expression profiling, physiological, biochemical and biophysical analyses. I identified the AmtR regulon and showed that AmtR was a transcriptional repressor of an urea degradation pathway. I identified xanthine and allantoin as ligands of mycobacterial AmtR and showed that addition of these metabolites had no effect on the release of AmtR from DNA. In further work, I demonstrated that deletion of the gene cadC in M. smegmatis resulted in a severe growth defect manifested as cell lysis during growth on rich medium. Subsequently, I identified the CadC regulon that included genes involved in the diaminopimelate (DAP) and lysine biosynthesis pathway. Supplementation with DAP or lysine could not rescue the growth defect of the ∆cadC mutant. Furthermore, I showed that M. smegmatis has a high-affinity lysine uptake system that exhibited high rates of lysine transport during growth in minimal medium, which was significantly reduced during growth in rich medium. My data suggest that a ∆cadC mutant is defective in the generation or replenishment of intracellular lysine and DAP levels that are essential for growth and survival in mycobacteria. I conclude that M. smegmatis has a broad network of regulatory systems that together enable M. smegmatis to adapt its nitrogen metabolism to rapidly changing environments
Purification, crystallization, and properties of F1-ATPase complexes from the thermoalkaliphilic Bacillus sp. strain TA2.A1.
No full textRecently, we reported the cloning of the atp operon encoding for the F(1)F(0)-ATP synthase from the extremely thermoalkaliphilic bacterium Bacillus sp. strain TA2.A1. In this study, the genes encoding the F(1) moiety of the enzyme complex were cloned from the atp operon into the vector pTrc99A and expressed in Escherichia coli in two variant complexes, F(1)-wt consisting of subunits alpha(3)beta(3)gammadeltaepsilon and F(1)Deltadelta lacking the entire delta-subunit as a prerequisite for overproduction and crystallization trials. Both F(1)-wt and F(1)Deltadelta were successfully overproduced in E. coli and purified in high yield and purity. F(1)Deltadelta was crystallized by micro-batch screening yielding three-dimensional crystals that diffracted to a resolution of 3.1A using a synchrotron radiation source. After establishing cryo and dehydrating conditions, a complete set of diffraction data was collected from a single crystal. No crystals were obtained with F(1)-wt. Data processing of diffraction patterns showed that F(1)Deltadelta crystals belong to the orthorhombic space group P2(1)2(1)2(1) with unit cell parameters of a=121.70, b=174.80, and c=223.50A, alpha, beta, gamma=90.000. The asymmetric unit contained one molecule of bacterial F(1)Deltadelta with a corresponding volume per protein weight (V(M)) of 3.25A(3) Da(-1) and a solvent content of 62.1%. Silver staining of single crystals of F(1)Deltadelta analyzed by SDS-PAGE revealed four bands alpha, beta, gamma, and epsilon with identical M(r)-values as those found in the native F(1)F(0)-ATP synthase isolated from strain TA2.A1 membranes. ATPase assays of F(1)Deltadelta crystals exhibited latent ATP hydrolytic activity that was highly stimulated by lauryldimethylamine oxide, a hallmark of the native enzyme
