Creating the on-line documentary: a satellite solution

[Abstract]: The online documentary, A Satellite Solution, is a case study investigation into how digital communications (primarily satellite TV) have impacted the quality of life of a rural community comprising 50 households in southeast Queensland (Australia) between 1999 and 2006. The production depicts a community-mediated process by which these residents adopted and then responded to receiving free-to-air TV services for the first time. The author, instigated and facilitated the project in the community and as well, recorded and produced all the material contained in the in the documentary. The paper will highlight the production components of the research set against the context of this participatory activity.This online documentary is a web site containing research materials (policy documents, significant correspondence and reports) video interviews and location sequences, maps and technical information such as, how to install a satellite system, where to find free-to-air satellite services and what satellite broadband incentives are available etc. Importantly it also represents innovation in film and television and particularly, the researcher's selected art form, the documentary. This paper, takes a practice focus and will document the production of the web site and how this new form impacts on the production style of traditional linear production and as well, what filmmakers working in this emerging non-linear form may need to plan for. This project formed the practical component for a recently completed research degree, Doctor of Visual Arts (Griffith), by the author

The People\u27s War: ldentification and the Logic of Good Reasons in British Propaganda in the U.S., 1939-1941

This study examines the persuasive nature of British propaganda in the United States between the years of 1939 and 1941. Radio scripts, serialized publications and pamphlets produced for distribution during this period are examined for the use of Burke\u27s ( 1969) concept of identification and their ability to meet to the standards of Fisher\u27s (1989) logic of good reasons. The study concludes that British propaganda made extensive use of identification and meets the standards of the logic of good reasons. The study also identifies three phases of British propaganda in which slightly different persuasive approaches are used

Analysis of the mechanism by which calcium negatively regulates the tyrosine phosphorylation cascade associated with sperm capacitation

The capacitation of mammalian spermatozoa involves the activation of a cAMP-mediated signal transduction pathway that drives tyrosine phosphorylation via mechanisms that are unique to this cell type. Controversy surrounds the impact of extracellular calcium on this process, with positive and negative effects being recorded in independent publications. We clearly demonstrate that the presence of calcium in the external medium decreases tyrosine phosphorylation in both human and mouse spermatozoa. Under these conditions, a rise in intracellular pH was recorded, however, this event was not responsible for the observed changes in phosphotyrosine expression. Rather, the impact of calcium on tyrosine phosphorylation in these cells was associated with an unexpected change in the intracellular availability of ATP. Thus, the ATP content of both human and mouse spermatozoa fell significantly when these cells were incubated in the presence of external calcium. Furthermore, the removal of glucose, or addition of 2-deoxyglucose, decreased ATP levels within human spermatozoon populations and induced a corresponding decline in phosphotyrosine expression. In contrast, the mitochondrial inhibitor rotenone had no effect on either ATP levels or tyrosine phosphorylation. Addition of the affinity-labeling probe 8-N3 ATP confirmed our prediction that spermatozoa have many calcium-dependent ATPases. Moreover, addition of the ATPase inhibitor thapsigargin, increased intracellular calcium levels, decreased ATP and suppressed tyrosine phosphorylation. Based on these findings, the present study indicates that extracellular calcium suppresses tyrosine phosphorylation by decreasing the availability of intracellular ATP, and not by activating tyrosine phosphatases or inhibiting tyrosine kinases as has been previously suggested.Mark A.

Functional group conflict in information systems development

This paper discusses how interpersonal conflict between IS developers and clients can disrupt IS projects.  It is suggested how potential problems can be avoided by getting the \u27soft\u27 factors right which can lead to improvements in information systems development (ISD) processes.  However little is being done in most organisations to review success from this perspective.  Measurement of ISD quality tends to favour the product rather than the human drivers that influence the development of the product.  Several ideas are put forward that can be used to resolve conflict and tp better involve stakeholders in the ISD process

The workload implications of haptic displays in multi-display environments such as the cockpit : dual-task interference of within-sense haptic inputs (tactile/proprioceptive) and between-sense inputs (tactile/proprioceptive/auditory/visual)

Visual workload demand within the cockpit is reaching saturation, whereas the haptic sense (proprioceptive and tactile sensation) is relatively untapped, despite studies suggesting the benefits of haptic displays. MRT suggests that inputs from haptic displays will not interfere with inputs from visual or auditory displays. MRT is based on the premise that multisensory integration occurs only after unisensory processing. However, recent neuroscientific findings suggest that the distinction between unisensory versus multisensory processing is much more blurred than previously thought. This programme of work had the following two research objectives: 1. To examine whether multiple haptic inputs can be processed at the same time without performance decrement - Study One 2. To examine whether haptic inputs can be processed at the same time as visual or auditory inputs without performance decrement - Study Two In Study One participants performed dual-tasks, consisting of same-sense tasks (tactile or proprioceptive) or different-sense tasks (tactile and proprioceptive). These tasks also varied in terms of processing code, in line with MRT. The results found significantly more performance decrement for the same-sense dual-tasks than for the different-sense dual-tasks, in accordance with MRT, suggesting that performance will suffer if two haptic displays of the same type are used concurrently. An adjustment to the MRT model is suggested to incorporate these results. In Study Two, participants performed different-sense dual-tasks, consisting of auditory or visual tasks with tactile or proprioceptive tasks. The tasks also varied in terms of processing code. Contrary to MRT, the results found that when processing code was different, there was significant performance decrement for all of the dual-tasks, but not when processing code was the same. These results reveal an exception to two key MRT rules, the sensory resource rule and the processing code rule. It is suggested that MRT may be oversimplistic and other factors highlighted by recent neuroscientific research should be taken into account in theories of dual-task performance.EThOS - Electronic Theses Online ServiceGBUnited Kingdo
