    The vortex-glass-liquid transition in Bi---Sr---Ca---Cu---O (BSCCO) intergrowth single crystals in which some CuO2 trilayers are inserted into the Bi2Sr2CaCu2O8 matrix has been studied. The curvature of the log V-logI curves for CuO2 trilayers is found to change from negative to positive with increasing magnetic field and a scaling behaviour for the vortex-glass state is observed. The magnetic field dependence of the vortex-glass transition temperature, TG, qualitatively obeys the relation H(TG) (Tc − Tg)2v0, with v0 = 1.15 ± 0.2, which is larger than the 2/3 predicted theoretically for an isotropic 3D system. Our results reveal that the vortex-glass transition exists in a system constructed with CuO2 trilayers.

    A raft of models and definitions of SoTL exist and the best appear to transcend disciplinary contexts, and are sufficiently robust for academics to measure scholarly practices. Critical engagement with the scholarly literature is necessary for academics to gain a realistic view of where their work practices are situated within the scholarly domain. Because academic staff are disciplinary experts they are best placed to comment on whether the models of scholarship describe the scholarship of learning and teaching within the context of their own disciplines as well as within the confines of the Australian higher education sector. This paper pushes the existing debates on reconciling what evidence of scholarship in the disciplines actually is and what is considered valid, and in doing so uncovers why the process of reconciliation, between current practice and supporting evidence, remains elusive. Higher education academics need to identify and reconcile tacit disciplinary knowledge with their SoTL approach in order to unpack the complexity and value of their practices. Enabling academic staff to annotate their activities, roles and accomplishments and then map these items onto the various models of scholarship will enrich the status of scholarship of teaching and learning within the higher education sector.

    INTRODUCTION Photovoltaic (solar) cells (Corkish, 2004) are semiconductor devices that directly create electric current and voltage from the collection of photons (quanta of light). They convert sunlight to electricity silently and without moving parts, require little maintenance, are reliable, being sold with warranties of up to twenty-five years, generate no greenhouse gases in operation and are modular, rapidly deployable and particularly suited to urban rooftops, façades and similar applications. Hence, they are easily located close to where electricity is consumed. Solar cells of 15% efficiency covering an area equivalent to just 0.25% of the global area under crops and permanent pasture could meet all the world's primary energy requirements today (Archer and Hill, 2001), yet most or all of that area could be otherwise alienated land, such as on buildings, for example. "On any given day, the solar energy falling on a typical oilfield in the Middle East is far greater than the energy contained in the oil extracted from it." (CarbonFree, 2006). However, solar cells remain an expensive option for most power generation requirements relative to fossil and nuclear sources, especially if the natural environment is attributed little or no value, and to some other sustainable options such as the enhancement energy efficiency, solar thermal (eg. solar water heating) or wind energy. Photovoltaics are synergistic with efficiency enhancement and solar thermal use and are usually more easily applied in urban situations than are wind turbines. Here, we aim to acquaint practising architects, builders and engineers with the fundamentals of solar photovoltaic energy production and devices and building-related applications (Green, 1995, Wenham et al., 2006, Prasad & Snow, 2005, Strong et al., 2005, Sick, 1996).
