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

A systematic review of sport and dance participation in healthy young people (15-24 years) to promote subjective wellbeing

We know that taking part in physical activity like sport and dance can bring wellbeing benefits, such as being more satisfied with life and happier, and feeling less anxious and depressed. Most of the evidence is however about adults. This review was carried out to investigate the relationships between subjective wellbeing (SWB) and taking part in sport and dance for healthy young people (15-24 years). Healthy people were defined as those without a condition diagnosed by a health professional. SWB describes wellbeing in terms of the good and bad feelings arising from what people do and how they think. The focus of this review was agreed through on-going collaborative engagement with UK-wide stakeholders representing policy, commissioning and managing, service delivery, and scholars from both academic and non-academic organisations. We examined studies from the past 10 years and found that there is limited good quality evidence, and very little conducted in the UK. The review includes published findings from 977 participants across six countries - China, Korea, India, Turkey, Sweden and the USA. In some studies, participants were predominantly female. A wide variety of wellbeing measures were used. The most common form of sport/dance related activity was based on meditative practices (yoga and Baduanjin Qigong). Other physical activities reported included body conditioning, aerobic exercise, dance training, hip hop dance and sports including volleyball, ice skating, Nintendo Wii Active Games. We included evidence from recent unpublished reports (grey literature) produced by or for sport and dance organisations since 2013. Participants in the evaluations were both male and female with a mean age between 13-24 years and were engaged in UK-based programmes of sport and dance. Findings illustrate that depending on activity type and delivery mode, taking part is associated with wellbeing improvements connected to social connectedness, pleasure, sense of purpose, confidence, interpersonal skills, happiness, relaxation, creative skills and expression, aspiration and ambition. Taking part was also associated with negative wellbeing connected to concerns about competency and capability. Overall, the evidence available in this review suggests that yoga-type activities have the potential to improve subjective wellbeing and that group-based and peer supported sport and dance programmes may promote wellbeing enhancement in youth groups. The evidence in this review provides limited promising findings upon which sport and dance programmes for wellbeing improvement could be developed. The lack of evidence identified in this review does not necessarily mean that wellbeing benefits are not accrued from taking part in sport and dance. There is scope to build evidence on wellbeing outcomes of sport and dance in healthy young people through well-designed, rigorous and appropriate research methods which are underpinned by relevant theory and use established methods of analysis

A systematic review of the subjective wellbeing outcomes of engaging with visual arts for adults (“working-age”, 15-64 years) with diagnosed mental health conditions

The importance of the visual arts in contributing to the wellbeing of adults with mental health conditions has been little documented beyond some insightful and influential interventions and exploratory studies. Initiatives such as Arts on Prescription projects have, in the UK provided examples of the positive effects that engagement in artistic and creative activity can have, and some of these have been documented in small-scale studies of interventions. Most of the evidence has been perceived as positive but of limited scale. In this context, this review was carried out to examine in a more focused way the ‘subjective wellbeing’ (SWB) outcomes of engagement with the visual arts for adults with a background history of mental health conditions. SWB embraces both the positive and negative feelings that arise in individuals based on their view of the world, how they think about themselves and others, and what they do in the interactions and practices of everyday life. Adult subjects in the studies included in this review were of ‘working-age’ (15-64 years). The focus of the review and the precise research question were agreed at inception sessions of the research team, and in collaborative engagement with stakeholders in the areas of policy, service-delivery, project and evaluation commissioning, and research and scholarship in the spheres of the visual arts and mental health. Published studies from the past 10 years were studied for the review, and their findings synthesised and integrated into an evaluation of the state of knowledge in the field, in terms of the specifics of the research questions. We found that there is limited high-quality evidence, though case studies from the UK have provided important and consistent findings, corroborated by grey literature that has reported on interventions and projects. The review includes published findings based on data on/from 163 participants across four countries – Australia, Sweden, the UK, and the USA. Overall, female respondents outnumbered male respondents. A wide variety of wellbeing measures were used in some quantitative, statistical studies. In-depth interviews dominated the qualitative studies, giving voice to the experiences of individual subjects. The visual arts practices that featured in the studies included forms of painting or drawing, art appreciation with selected art forms, artmaking culminating in an exhibition, and more general creative and craft activities that included visual artefacts such as ceramics or sculpture. Evidence we include from recent unpublished reports (grey literature) was produced by or for visual arts organisations since 2014. Participants in the evaluations were both male and female and were engaged in UK-based arts interventions, many via community arts or ‘Arts on Prescription’ types of intervention. Overall, the evidence available in this review has shown that engagement in the visual arts for adults with mental health conditions can reduce reported levels of depression and anxiety; increase self-respect, self-worth and self-esteem; encourage and stimulate re-engagement with the wider, everyday social world; and support in participants a potential renegotiation of identity through practice-based forms of making or doing. The most effective ‘working ways to wellbeing’ are also confirmed in processes of implementation that ensure provision of secure safe-space and havens for interventions; that recognise the value of non-stigmatising settings; and that support and sustain collaborative facilitation of programmes and sessions. 4 Some negative dimensions of engagement with the visual arts were also identified, including stress and pressure felt to complete activities or commit to artmaking, and the very real fear that the end of an intervention would mean the return to a world of anxiety, decreasing confidence and social isolation. The review shows that for adults starting visual arts activities or programmes, the subjective wellbeing outcomes are, for the majority of participants, positive. This applies to men and women alike across the studies. The most convincing evidence has emerged from focused qualitative research designs, and makes clear that the most effective work in the field continues to lack the necessary resources and infrastructure that would ensure sustainable practices and interventions. Overall, there is some evidence of benefit in a weak field that could be strengthened by fuller monitoring of cohorts to evaluate the long-term effects of participants’ engagement with the visual arts

Human Metapneumovirus-associated Atypical Pneumonia and SARS

Acute pneumonia developed in a previously healthy man during the outbreak of severe acute respiratory syndrome (SARS) in southern China in March 2003. Antibiotic treatment was ineffective, and he died 8 days after illness onset. Human metapneumovirus was isolated from lung tissue. No other pathogen was found. Other etiologic agents should thus be sought in apparent SARS cases when coronavirus infection cannot be confirmed

Severe Acute Respiratory Syndrome–associated Coronavirus Infection

Whether severe acute respiratory syndrome–associated coronavirus (SARS-CoV) infection can be asymptomatic is unclear. We examined the seroprevalence of SARS-CoV among 674 healthcare workers from a hospital in which a SARS outbreak had occurred. A total of 353 (52%) experienced mild self-limiting illnesses, and 321 (48%) were asymptomatic throughout the course of these observations. None of these healthcare workers had antibody to SARS CoV, indicating that subclinical or mild infection attributable to SARS CoV in adults is rare

Laboratory Diagnosis of SARS

The virologic test results of 415 patients with severe acute respiratory syndrome (SARS) were examined. The peak detection rate for SARS-associated coronavirus occurred at week 2 after illness onset for respiratory specimens, at weeks 2 to 3 for stool or rectal swab specimens, and at week 4 for urine specimens. The latest stool sample that was positive by reverse transcription–polymerase chain reaction (RT-PCR) was collected on day 75 while the patient was receiving intensive care. Tracheal aspirate and stool samples had a higher diagnostic yield (RT-PCR average positive rate for first 2 weeks: 66.7% and 56.5%, respectively). Pooled throat and nasal swabs, rectal swab, nasal swab, throat swab, and nasopharyngeal aspirate specimens provided a moderate yield (29.7%–40.0%), whereas throat washing and urine specimens showed a lower yield (17.3% and 4.5%). The collection procedures for stool and pooled nasal and throat swab specimens were the least likely to transmit infection, and the combination gave the highest yield for coronavirus detection by RT-PCR. Positive virologic test results in patient groups were associated with mechanical ventilation or death (p < 0.001), suggesting a correlation between viral load and disease severity

Polymorphisms near TBX5 and GDF7 are associated with increased risk for Barrett's esophagus.

BACKGROUND & AIMS: Barrett's esophagus (BE) increases the risk of esophageal adenocarcinoma (EAC). We found the risk to be BE has been associated with single nucleotide polymorphisms (SNPs) on chromosome 6p21 (within the HLA region) and on 16q23, where the closest protein-coding gene is FOXF1. Subsequently, the Barrett's and Esophageal Adenocarcinoma Consortium (BEACON) identified risk loci for BE and esophageal adenocarcinoma near CRTC1 and BARX1, and within 100 kb of FOXP1. We aimed to identify further SNPs that increased BE risk and to validate previously reported associations. METHODS: We performed a genome-wide association study (GWAS) to identify variants associated with BE and further analyzed promising variants identified by BEACON by genotyping 10,158 patients with BE and 21,062 controls. RESULTS: We identified 2 SNPs not previously associated with BE: rs3072 (2p24.1; odds ratio [OR] = 1.14; 95% CI: 1.09-1.18; P = 1.8 × 10(-11)) and rs2701108 (12q24.21; OR = 0.90; 95% CI: 0.86-0.93; P = 7.5 × 10(-9)). The closest protein-coding genes were respectively GDF7 (rs3072), which encodes a ligand in the bone morphogenetic protein pathway, and TBX5 (rs2701108), which encodes a transcription factor that regulates esophageal and cardiac development. Our data also supported in BE cases 3 risk SNPs identified by BEACON (rs2687201, rs11789015, and rs10423674). Meta-analysis of all data identified another SNP associated with BE and esophageal adenocarcinoma: rs3784262, within ALDH1A2 (OR = 0.90; 95% CI: 0.87-0.93; P = 3.72 × 10(-9)). CONCLUSIONS: We identified 2 loci associated with risk of BE and provided data to support a further locus. The genes we found to be associated with risk for BE encode transcription factors involved in thoracic, diaphragmatic, and esophageal development or proteins involved in the inflammatory response

Can asthma control be improved by understanding the patient's perspective?

Clinical trials show that asthma can be controlled in the majority of patients, but poorly controlled asthma still imposes a considerable burden. The level of asthma control achieved reflects the behaviour of both healthcare professionals and patients. A key challenge for healthcare professionals is to help patients to engage in self-management behaviours with optimal adherence to appropriate treatment. These issues are particularly relevant in primary care, where most asthma is managed. An international panel of experts invited by the International Primary Care Respiratory Group considered the evidence and discussed the implications for primary care practice
