Improvisation in visual art practice using a photographic process

In this article I discuss how I have come to understand embodied processes in my visual art practice using photography. I danced professionally for 25 years and performed in various contexts including classical ballet repertoire, contemporary dance, and commercial dance. I choreographed for various productions working with a group of dancers for seven years before studying visual art. I experienced a particular sense of embodiment as a live performer in which prescribed movements were learnt, performed and repeated as if second nature. Transitioning into a conceptually based visual art practice the creative process was flipped around. Using painting, sculpture, performance (in a different context) and photographic methods I explored ideas from which forms such as video/audio installations, photography, performance art and painting emerged mostly in a gallery context. Although I still think of forms of movement as content, in a visual art practise the idea or concept invokes form.

Dance review: Metadata explores shadows and space

The interplay between movement, human physicality and complex projections are brought to the fore across the two works that make up Metadata. The artists offer a variety of interpretations about how that relationship might deepen our understanding of space, volume and the passage of time within a performance context.

Transmissible cancers in an evolutionary context.

Cancer is an evolutionary and ecological process in which complex interactions between tumour cells and their environment share many similarities with organismal evolution. Tumour cells with highest adaptive potential have a selective advantage over less fit cells. Naturally occurring transmissible cancers provide an ideal model system for investigating the evolutionary arms race between cancer cells and their surrounding micro-environment and macro-environment. However, the evolutionary landscapes in which contagious cancers reside have not been subjected to comprehensive investigation. Here, we provide a multifocal analysis of transmissible tumour progression and discuss the selection forces that shape it. We demonstrate that transmissible cancers adapt to both their micro-environment and macro-environment, and evolutionary theories applied to organisms are also relevant to these unique diseases. The three naturally occurring transmissible cancers, canine transmissible venereal tumour (CTVT) and Tasmanian devil facial tumour disease (DFTD) and the recently discovered clam leukaemia, exhibit different evolutionary phases: (i) CTVT, the oldest naturally occurring cell line is remarkably stable; (ii) DFTD exhibits the signs of stepwise cancer evolution; and (iii) clam leukaemia shows genetic instability. While all three contagious cancers carry the signature of ongoing and fairly recent adaptations to selective forces, CTVT appears to have reached an evolutionary stalemate with its host, while DFTD and the clam leukaemia appear to be still at a more dynamic phase of their evolution. Parallel investigation of contagious cancer genomes and transcriptomes and of their micro-environment and macro-environment could shed light on the selective forces shaping tumour development at different time points: during the progressive phase and at the endpoint. A greater understanding of transmissible cancers from an evolutionary ecology perspective will provide novel avenues for the prevention and treatment of both contagious and non-communicable cancers.

Global virtual engineering teams (GVETs): a fertile ground for research in Australian construction projects context

Implementation of global virtual engineering teams (GVETs) commenced since at least two decades ago, but construction has been behind other industries in terms of harnessing this new paradigm. Nevertheless, GVETs are receiving increasing attention within the construction context due to numerous potential benefits they can bring about for the projects. On the other hand, the research about GVETs in Australia is still in its embryonic stages. Australian scholars noticeably have paid scant attention to GVETs in comparison to their colleagues in other developed countries. This paper assumes the process of implementation of a GVET as an isolated project. The study then highlights the well-known main areas of necessary knowledge for managing a GVET project within the construction context based on a project lifecycle approach. Recognizing the weaknesses of existing literature, the paper sets out an agenda for further research within Australian construction projects.

Exploring the effectiveness of true abnormal data elimination in context-aware web services recommendation

Recent years have witnessed a growing interest in context-aware recommender system (CARS), which explores the impact of context factors on personalized Web services recommendation. Basically, the general idea of CARS methods is to mine historical service invocation records through the process of context-aware similarity computation. It is observed that traditional similarity mining process would very likely generate relatively big deviations of QoS values, due to the dynamic change of contexts. As a consequence, including a considerable amount of deviated QoS values in the similarity calculation would probably result in a poor accuracy for predicting unknown QoS values. In allusion to this problem, this paper first distinguishes two definitions of Abnormal Data and True Abnormal Data, the latter of which should be eliminated. Second, we propose a novel CASR-TADE method by incorporating the effectiveness of True Abnormal Data Elimination into context-aware Web services recommendation. Finally, the experimental evaluations on a real-world Web services dataset show that the proposed CASR-TADE method significantly outperforms other existing approaches.

Adopting an active learning approach to teaching in a research-intensive higher education context transformed staff teaching attitudes and behaviours

The conventional lecture has significant limitations in the higher education context, often leading to a passive learning experience for students. This paper reports a process of transforming teaching and learning with active learning strategies in a research-intensive educational context across a faculty of 45 academic staff and more than 1000 students. A phased approach was used, involving nine staff in a pilot phase during which a common vision and principles were developed. In short, our approach was to mandate a move away from didactic lectures to classes that involved students interacting with content, with each other and with instructors in order to attain domain-specific learning outcomes and generic skills. After refinement, an implementation phase commenced within all first-year subjects, involving 12 staff including three from the pilot group. The staff use of active learning methods in classes increased by sixfold and sevenfold in the pilot and implementation phases, respectively. An analysis of implementation phase exam questions indicated that staff increased their use of questions addressing higher order cognitive skills by 51%. Results of a staff survey indicated that this change in practice was caused by the involvement of staff in the active learning approach. Fifty-six percent of staff respondents indicated that they had maintained constructive alignment as they introduced active learning. After the pilot, only three out of nine staff agreed that they understood what makes for an effective active learning exercise. This rose to seven out of nine staff at the completion of the implementation phase. The development of a common approach with explicit vision and principles and the evaluation and refinement of active learning were effective elements of our transformational change management strategy. Future efforts will focus on ensuring that all staff have the time, skills and pedagogical understanding required to embed constructively aligned active learning within the approach.
