Understanding success and failure in innovative Australian resource processing projects

This thesis in concerned with the understanding of success and failure of innovation in resource processing, a sector that is central to the Australian economy. Decline in ore grade, complexity of available ore resources, increases in labour and capital cost, and increased market demand have driven innovation and larger resource processing projects. The outcomes from innovation investment have been disappointing, and not well understood. This thesis aims to understand why so many large resource processing projects fail, and what factors have been critical in other projects that succeed. It proposes a new model for innovation investment, based on public domain data and an outsider view. Five criteria are used in this thesis to classify success and failure of large resource processing projects; that (1) the project and firm made a profit, in failure the project made a loss, (2) the production in the first 36 months of operation is 90% or more of nameplate capacity, while a failure is less than 70%, (3) return on investment is below 105 months, failure above 105 months, average for successful projects is found to be 53 months,. (4) failure sees project and or firm fail, with the plant selling for less than 20% of cost, success sees the project continue to produce at close to capacity, and if sold was value at close to investment, and (5) the successful process is reproduced; in the case of failure it is not. The thesis examines a sample of 67 resource processing projects in Australia initially valued at over $100 million each, over an 18 year interval between 1993 and 2010. The projects totalled$45.3 billion in value with 73% of classified as successful, while 15 projects failed. Four hypotheses are proposed and tested, each respectively relating to one of the following four factors; (1) Firm competence, (2) new process innovation, (3) government involvement in value adding, and (4) information asymmetry and strategic misrepresentation

"Strenuous Competition on the field of play, Diplomacy off it" – The 1908 London Olympics, Theodore Roosevelt, Arthur Balfour, and Transatlantic Relations

Through the lens of the 1908 Summer Olympic Games, and the sport-based ideals and philiospohies of the US president Roosevelt and the UK prime minister Balfour, this article explores the nature of transatlantic relations. It shows how views of sport cross into the political sphere and can be used in serious diplomatic relations and strategies

A comparison of saccadic and blink suppression in normal observers

Recent research suggests that blink and saccadic suppression are produced by the same mechanism (Volkmann, 1986; Uchikawa & Sato, 1995; Ridder & Tomlinson, 1993, 1995). These studies demonstrated that blink and saccadic suppression have the same effect on various visual functions. However, none of these studies made a comparison of blink and saccadic suppression in the same individual. The purpose of this study was to compare the effects of blink and saccadic suppression on contrast sensitivity functions in the same subject. The effect of saccadic suppression on the contrast sensitivity function in three normal observers was determined. Employing a two-alternative, forced-choice technique, thresholds were measured for seven spatial frequencies. At each spatial frequency, the threshold was determined immediately following detection of a voluntary saccade. The magnitude of suppression was taken as the log ratio of the contrast sensitivities obtained while foveating the stimulus and those obtained during saccades. The magnitude of saccadic suppression was found to increase as the saccade amplitude increased and to be spatial-frequency dependent. Low spatial frequencies were suppressed more than high spatial frequencies. The blink suppression data have been measured previously (Ridder & Tomlinson, 1993). Saccadic and blink suppression were qualitatively similar. A vertical shift of the data brought the saccadic and blink suppression data into register. These results suggest that blink and saccadic suppression are produced by the same or similar mechanisms

Communication about HIV and death: Maternal reports of primary school-aged children's questions after maternal HIV disclosure in rural South Africa

Introduction: Children's understanding of HIV and death in epidemic regions is under-researched. We investigated children's death-related questions post maternal HIV-disclosure. Secondary aims examined characteristics associated with death-related questions and consequences for children's mental health. Methods: HIV-infected mothers (N = 281) were supported to disclose their HIV status to their children (6–10 years) in an uncontrolled pre-post intervention evaluation. Children's questions post-disclosure were collected by maternal report, 1–2 weeks post-disclosure. 61/281 children asked 88 death-related questions, which were analysed qualitatively. Logistic regression analyses examined characteristics associated with death-related questions. Using the parent-report Child Behaviour Checklist (CBCL), linear regression analysis examined differences in total CBCL problems by group, controlling for baseline. Results: Children's questions were grouped into three themes: ‘threats’; ‘implications’ and ‘clarifications’. Children were most concerned about the threat of death, mother's survival, and prior family deaths. In multivariate analysis variables significantly associated with asking death-related questions included an absence of regular remittance to the mother (AOR 0.25 [CI 0.10, 0.59] p = 0.002), mother reporting the child's initial reaction to disclosure being “frightened” (AOR 6.57 [CI 2.75, 15.70] p=<0.001) and level of disclosure (full/partial) to the child (AOR 2.55 [CI 1.28, 5.06] p = 0.008). Controlling for significant variables and baseline, all children showed improvements on the CBCL post-intervention; with no significant differences on total problems scores post-intervention (β -0.096 SE1.366 t = -0.07 p = 0.944). Discussion: The content of questions children asked following disclosure indicate some understanding of HIV and, for almost a third of children, its potential consequence for parental death. Level of maternal disclosure and stability of financial support to the family may facilitate or inhibit discussions about death post-disclosure. Communication about death did not have immediate negative consequences on child behaviour according to maternal report. Conclusion: In sub-Saharan Africa, given exposure to death at young ages, meeting children's informational needs could increase their resilience

GEORGE BERNARD SHAW

O autor afirma que Shaw, em qualquer avaliação da literatura britânica, durante o século passado e o começo deste, merece um lugar proeminente.Uma das razões para isso, é que Shaw foi um escritor que percebeu a necessidade premente das mudanças sociais e tentou tornar essa necessidade evidente aos olhos dos outros.Desenvolvendo esse tema, o autor trata da centralidade das questões levantadas nas peças de Shaw, em relação aos problemas sociais, políticos, culturais e morais da época. No desenvolvimento cênico daquelas questões, Shaw desenvolve uma técnica teatral rigorosa e minuciosa em que os menoresdetalhes, formando um conjunto de expressão, são previamente controlados pelo dramaturgo, em suas instruções cênicas, onde o elemento visual do esquema da peça é tão importante como o elemento verbal, e os gestos dos atores são cuidadosamente cronometrados, de modo que, lendo-se uma ação descrita, ela pode representar quase nada, mas sendo encenada, elaadquire um alto valor de comunicação
