Teachers are at the forefront of Information Communication Technology (ICT) use in schools. Teachers face many challenges and competing priorities such as literacy, numeracy and changing curriculum frameworks and are expected to adopt new ICT practices to improve students¿ outcomes. Effective professional development (PD) methods must be identified and implemented. This research examined two core issues: (1) experienced teachers' perceptions of their ICT practices and (2) how PD courses have affected these practices. This case study and its findings has important implications for the implementation of effective PD in schools.

Axillary shoots of Nicotiana benthamiana were regenerated from nodal explants in two weeks using MS media supplemented with the cytokinin, kinetin (0.5 mg/L), and the auxin, indole-3-butyric acid (IBA) (0.1 mg/L). Ninety two percent of shoots were 2.1-20 mm tall, a size ideal for root induction. After transfer to hormone-free MS they readily produced roots within seven days, with phenotypically normal, fully developed plants being obtained within four weeks. Leaf chlorosis due to iron deficiency was observed in plants over time, however, this was overcome by doubling the concentration of inorganic iron. This rapid micro-propagation system is particularly useful for the in vitro mass production of N. benthamiana plants for various biotechnological applications.

The policy environment for regional natural resource management (NRM) has shifted considerably since it was first introduced in the early 2000s. This workshop will explore the impact of current policy on NRM planning and action through presentations and workshop discussion. To set the scene for the workshop discussion presentations will consider: 1) the impact of evolving national and state NRM policy in Australia; 2) how Australian NRM compares to other countries; 3) governance risks to NRM delivery; and 4) regional responses to NRM delivery. During the workshop element, participants from across regions will share their experiences and explore implications of current policy on the business of regional NRM.

Complex intersecting social, economic and environmental dilemmas in Australia's Cape York Peninsula present a number of challenges for planners seeking to develop and implement land use and natural resource management (NRM) plans. There have been five different attempts at land use and NRM planning in Cape York Peninsula over the last 20 years. These processes have (to greater or lesser extents) failed to deliver community-owned and government-supported plans to guide development and/or the management of the region's natural resources. The region is remote, sparsely populated, and home to a significant Indigenous population. Much of the contestation within the region surrounds the access, use and ownership of the region's internationally valuable natural resources. This paper reviews, from the literature, the relevancy and applicability of criteria for best practice planning and governance. A range of identified best practice governance and planning principles are applied to assess the governance arrangements for planning in the Peninsula. The paper finds that decision-making arrangements for land use and NRM planning in the Peninsula are still in their infancy and are inadequate to support effective outcomes. The paper concludes that broader attention to best practice principles in governance for planning is needed to improve planning outcomes.

A longitudinal qualitative study was conducted with CEOs of 12 fundraising organisations across Australia to answer the question - how mights a change in the CEO's fundraising knowledge improve fundraising activity and outcomes for their organisation? The CEOs along with the inaugural Australian Grantmaker of the Year, Caitriona Fay from Perpetual and lead researcher Dr Wendy Scaife travelled to San Antonio, Texas, USA to attend the annual Association of Fundraising Professionals (AFP) conference in March 2014. Participants identified five main success factors for such group learning initiatives about fundraising: - Getting away from the day to day business of running the organisation - Informal, social time to debrief and get to know others - Diversity of organisations whereby no one was in direct competition to others - Commitment, openness and willingness of individuals to participate - Group facilitation This research has been supported by the Perpetual Foundation – Trustees Endowment, The Edward Corbould Charitable Trust, and the Samuel and Eileen Gluyas Charitable Trust under the management of Perpetual Trustee Company Ltd.

Australian fundraisers and their organisational leaders (CEOs and board members) diverge sometimes in how they think about fundraising. In fact, eight key differences emerged in the recent Australian study that sparked this paper. A strong fundraising/leadership accord in attitudes toward fundraising would seem to be important, especially in tightened funding regimes. Both demand and competition for funding beyond the government dollar is growing. Many organisations are moving into community fundraising for the first time due to imperilled government funding. The sophistication of all donation sources is likewise on the rise. These factors add complexity to the fundraising role and to the task of boards and CEOs in managing fundraising strategy and activity. Some variances in professional outlook might be predictable between fundraisers and fundraising organisation leaders. However, the differences found in our study are in areas that potentially affect the organisation’s ability to fill its mission. It is advisable then to ‘mind the gap’ and also to explore it.

Australia in a sense has two histories: that of its indigenous Aboriginal and Torres Strait Islander people based on a traditional culture of mutual dependence and reciprocal altruism (Turner, 1981) and the other from its eighteenth century colonization as a British penal outpost. These colonial overtones have proved an abiding cultural force. A dominant government presence, British legal platform, and ongoing sense that ‘the government will provide’ remain today (Liffman, 2008; McDonald & Scaife, 2011).

Establishing communities of practice is a tenuous process fraught with a multiplicity of experiences and artefacts that come together and either strengthen or hinder the practice. In this chapter a diverse group of teacher educators reflect on their experience of being brought together to form a community of practice in the scholarship of teaching. Their task was to collaboratively consider and problem solve some of the key issues currently impacting on teacher education, and more broadly on higher education. How the group negotiated shared meaning and purpose is a focus of the chapter. There were many challenges and issues that the group needed to collaboratively and individually solve before progressing towards shared meaning. The experiences of the assigned leaders of this group are also considered, yet it is the evolving understanding of leadership through collaboration that is of greater importance. The interplay of the experiences of all group members along with the artefacts and practices that reify the group’s purpose are considered. We explore how the group members began to understand how to work collaboratively across the boundaries of their disciplines, and how reflecting on their learning and participation in this group enabled them to work through issues that were constraining their progress.

The construction industry is a knowledge-based industry where various actors with diverse expertise create unique information within different phases of a project. The industry has been criticized by researchers and practitioners as being unable to apply newly created knowledge effectively to innovate. The fragmented nature of the construction industry reduces the opportunity of project participants to learn from each other and absorb knowledge. Building Information Modelling (BIM), referring to digital representations of constructed facilities, is a promising technological advance that has been proposed to assist in the sharing of knowledge and creation of linkages between firms. Previous studies have mainly focused on the technical attributes of BIM and there is little evidence on its capability to enhance learning in construction firms. This conceptual paper identifies six ‘functional attributes’ of BIM that act as triggers to stimulate learning: (1) comprehensibility; (2) predictability; (3) accuracy; (4) transparency; (5) mutual understanding and; (6) integration.

The Australian construction industry is often criticized for its comparatively low productivity. The most significant future productivity gains are predicted to arise from improvement in the firm’s project management. Information Communication Technologies (ICTs) are thought to offer such improvement. ICT adoption is particularly poor among Small and Medium Enterprises (SMEs). Existing studies provide only a general overview of adoption and diffusion of ICTs in SMEs, with no previous research measuring their readiness to adopt ICT. This paper outlines a theoretical approach to address this gap, exploring how to improve ICT adoption in Australian construction SMEs. A review of literature is undertaken to address the research question ‘What is the best conceptual approach to understanding ICT adoption in SMEs?’ The results emphasize the efficacy of a novel Technology Readiness and Acceptance Model (TRAM) to assess SMEs’ ICT implementation readiness. The proposed model consists of four major constructs to measure readiness comprising: - (1) optimism, - (2) innovativeness, - (3) discomfort and - (4) insecurity; two major constructs to measure technological acceptance comprising: - (1) perceived ease of use and - (2) perceived usefulness; and two extension variables comprising: - (1) self-efficacy and - (2) facilitating conditions. A limitation is that the performance of the conceptual model is yet to be tested empirically. Such research is planned in the coming year by the authors.

Decades of research has shown that the uptake of workplace ‘flexibility’ provisions set out in organizational/HR policies rests heavily on the support of line managers. However, the majority of scholarship addressing the intersection of managers’ roles and work-life integration has been employee-centred. That is, the literature primarily situates managers as gatekeepers to the effective implementation of work and family policies as they affect employees or workers, examining their role in, for example, approving requests to adjust or personalise employees’ work schedules; influencing whether employees are cross-trained to undertake the work of others during absences; publicising available policies; and creating norms supporting the use of formal provisions (Ryan & Ernst Kossek, 2008). Managers’ actions are primarily seen as key, contingent phenomena affecting the adoption and diffusion of work-life initiatives in an organization; consequently impacting on the work-life outcomes of subordinate employees (Bardoel, 2003; Gregory & Milner, 2012).

Background: Transthoracic echocardiography (TTE) during extra corporeal membrane oxygenation (ECMO) is important but can be technically challenging. Contrast-specific TTE can improve imaging in suboptimal studies. These contrast microspheres are hydrodynamically labile structures. This study assessed the feasibility of contrast echocardiography (CE) during venovenous (VV) ECMO in a validated ovine model. Method: Twenty-four sheep were commenced on VV ECMO. Parasternal long-axis (Plax) and short-axis (Psax) views were obtained pre- and postcontrast while on VV ECMO. Endocardial definition scores (EDS) per segment were graded: 1 = good, 2 = suboptimal 3 = not seen. Endocardial border definition score index (EBDSI) was calculated for each view. Endocardial length (EL) in the Plax view for the left ventricle (LV) and right ventricle (RV) was measured. Results: Summation EDS data for the LV and RV for unenhanced TTE (UE) versus CE TTE imaging: EDS 1 = 289 versus 346, EDS 2 = 38 versus 10, EDS 3 = 33 versus 4, respectively. Wilcoxon matched-pairs rank-sign tests showed a significant ranking difference (improvement) pre- and postcontrast for the LV (P < 0.0001), RV (P < 0.0001) and combined ventricular data (P < 0.0001). EBDSI for CE TTE was significantly lower than UE TTE for the LV (1.05 ± 0.17 vs. 1.22 ± 0.38, P = 0.0004) and RV (1.06 ± 0.22 vs. 1.42 ± 0.47, P = 0.0.0006) respectively. Visualized EL was significantly longer in CE versus UE for both the LV (58.6 ± 11.0 mm vs. 47.4 ± 11.7 mm, P < 0.0001) and the RV (52.3 ± 8.6 mm vs. 36.0 ± 13.1 mm, P < 0.0001), respectively. Conclusions: Despite exposure to destructive hydrodynamic forces, CE is a feasible technique in an ovine ECMO model. CE results in significantly improved EDS and increased EL.

Animal models of critical illness are vital in biomedical research. They provide possibilities for the investigation of pathophysiological processes that may not otherwise be possible in humans. In order to be clinically applicable, the model should simulate the critical care situation realistically, including anaesthesia, monitoring, sampling, utilising appropriate personnel skill mix, and therapeutic interventions. There are limited data documenting the constitution of ideal technologically advanced large animal critical care practices and all the processes of the animal model. In this paper, we describe the procedure of animal preparation, anaesthesia induction and maintenance, physiologic monitoring, data capture, point-of-care technology, and animal aftercare that has been successfully used to study several novel ovine models of critical illness. The relevant investigations are on respiratory failure due to smoke inhalation, transfusion related acute lung injury, endotoxin-induced proteogenomic alterations, haemorrhagic shock, septic shock, brain death, cerebral microcirculation, and artificial heart studies. We have demonstrated the functionality of monitoring practices during anaesthesia required to provide a platform for undertaking systematic investigations in complex ovine models of critical illness.
