Cloud computing : how does it differ from IT outsourcing and what are the implications for practice and research?

The purpose of this paper is to provide an evolutionary perspective of cloud computing (CC) by integrating two previously disparate literatures: CC and information technology outsourcing (ITO). We review the literature and develop a framework that highlights the demand for the CC service, benefits, risks, as well as risk mitigation strategies that are likely to influence the success of the service. CC success in organisations and as a technology overall is a function of (i) the outsourcing decision and supplier selection, (ii) contractual and relational governance, and (iii) industry standards and legal framework. Whereas CC clients have little control over standards and/or the legal framework, they are able to influence other factors to maximize the benefits while limiting the risks. This paper provides guidelines for (potential) cloud computing users with respect to the outsourcing decision, vendor selection, service-level-agreements, and other issues that need to be addressed when opting for CC services. We contribute to the literature by providing an evolutionary and holistic view of CC that draws on the extensive literature and theory of ITO. We conclude the paper with a number of research paths that future researchers can follow to advance the knowledge in this field.

Lung health care for Aboriginal and Torres Strait Islander Queenslanders : breathing easy is not so easy

Objectives In Aboriginal and Torres Strait Islander peoples in Queensland, to (a) determine the disease burden of common chronic lung diseases and (b) identify areas of need with respect to lung health services. Methods Literature reviews and analyses of hospitalisation and mortality data were used to describe disease epidemiology and available programs and services. Key stakeholder interviews and an online survey of health professionals were used to evaluate lung health services across the state and to identify services, needs and gaps. Results Morbidity and mortality from respiratory diseases in the Indigenous population is substantially higher than the non-Indigenous population across all age groups and regions. There are inadequate clinical services and resources to address disease prevention, detection, intervention and management in an evidence-based and culturally acceptable fashion. There is a lack of culturally appropriate educational resources and management programs, insufficient access to appropriately engaged Indigenous health professionals, a lack of multi-disciplinary specialist outreach teams, fragmented information systems and inadequate coordination of care. Conclusions Major initiatives are required at all levels of the healthcare system to adequately address service provision for Indigenous Queenslanders with lung diseases, including high quality research to investigate the causes for poor lung health, which are likely to be multifactorial.

���To educate you to be smart���: disaffected students and the purpose of school in the (not so clever) ���lucky country���

This paper contributes to conversations about school, post-compulsory and further education policy by reporting findings from a three-year study with disaffected students who have been referred to special ���behaviour��� schools. Contrary to popular opinion, our research finds that these ���ignorant yobs��� (Tomlinson, 2012) do value education and know what it is for. They also have aspirations for a secure, productive and fulfilled life, although it may not involve university level study. Importantly, we found that students who responded negatively with regard to the importance of schooling tended to envision future lives and occupations for which they believed school knowledge was unnecessary. The implications of this research for school, post-compulsory and further education policy are discussed.

Is it RIP for the IEP? The future of individual education plans in an era of accountability

This article presents a brief overview of the development of the Individual Education Plan (IEP) and prompts teachers to question its use and relevance in an era of accountability in Australian schools. Many Australian teachers do not realise that the IEP was adopted from the United States where is was legislated practice based on that country's Human Rights Legislation. It is not included in the Australian policy context. Though not embedded in the legislation of many other countries, it became a process and a product synonymous with the education of students with disability worldwide. In the era of standards-based education and curriculum for all, the relevance of the IEP process and product has been questioned or re-imaged in some Australian schools. The story of one school leader, Violet, is presented here as an example.

Enhancing the auditor's report : to what extent is there support for the IAASB's proposed changes?

This article outlines proposed reforms to auditor reporting currently being considered by the International Auditing and Assurance Standards Board (IAASB), and other key national and transnational standard-setters and regulatory bodies. It adds to recent academic contributions on reforming the auditor���s report by analyzing the 165 stakeholder responses to the IAASB���s 2012 Invitation to Comment: Improving the Auditor���s Report to determine levels of support for the IAASB���s proposed reforms, and the differences, if any, between the views of various respondents based on stakeholder groups (e.g. audit and assurance firms, users, preparers, regulators, etc.) and regional classifications. Guided by insights from communication theory, our results show the levels of stakeholder support for the IAASB���s proposed reforms addressing auditors��� expectations, information and communication gaps are mixed. The strongest overall support was for enhanced auditor reporting on other information attached to, or intended to be read with, the financial statements, and the least supported initiative was including additional information in the auditor���s report about the auditor���s judgements and processes. Whilst overall there is generally consensus across both stakeholder groups and regions concerning the various questions investigated, we highlight where statistically significant differences between groups do exist. Notably, North American respondents were less likely to support a number of the IAASB���s proposed reforms than their counterparts from other regions.

Keeping kids in school is not as simple as carrots and sticks

The OECD���s 2009 Jobs for Youth report, released on the heels of the global financial crisis, made a number of policy recommendations to the Australian government to prevent a rise in youth unemployment. Five years on, youth unemployment has risen from around 8% to 14.8%, and around one in five children do not complete year 12, according to data from the National Centre for Vocational Education Research...

When the price is not right: Technology price gouging in Australia

Apple Inc. has often portrayed itself as the champion of consumers, with its advertising campaigns on ���1984���, ���Think Different���, and ���Rip, Mix, Burn���. However, this reputation has been called into question after Apple refused to appear before the Parliament���s inquiry into IT Pricing in Australia and explain its pricing policies in Australia.

After 10 years of clinical trials with liraglutide, do we know whether it is beneficial in diabetes?

Type 2 diabetes remains an escalating world-wide problem, despite a range of treatments. The revelation that insulin secretion is under the control of a gut hormone, glucagon-like peptide 1 (GLP-1), led to a new paradigm in the management of type 2 diabetes. Liraglutide is a long acting GLP-1 receptor agonist used in the treatment of type 2 diabetes. The review considers the clinical trials with liraglutide. There are many comparator trials between liraglutide and other medicines for the treatment of type 2 diabetes, and these trials have shown that liraglutide lowers HbA1c and body weight, and is well tolerated. A large cardiovascular safety trial with liraglutide is presently being undertaken. After 10 years of clinical trials with liraglutide, we do not know whether liraglutide has cardiovascular safety in subjects with type 2 diabetes and high cardiovascular risk. Although this is not a requirement for registration by the Food and Drug Administration (FDA), in my opinion, they should reconsider this. We also do not presently know whether liraglutide has any beneficial effects on clinical cardiovascular outcomes.

Is there enough evidence with evolocumab and alirocumab (antibodies to proprotein convertase substilisin-kexin type, PCSK9) on cardiovascular outcomes to use them widely?

Introduction: Statins alone often do not reduce LDL cholesterol levels sufficiently to given maximum cardiovascular benefit. Thus, additional drugs are required to reduce the levels of LDL cholesterol. Monoclonal antibodies to PCSK9 have recently been shown to decrease LDL cholesterol, but it is not known whether they improve cardiovascular outcomes. Areas covered: Evaluation of two clinical trials reporting cardiovascular outcomes with antibodies to PCSK9; the OSLER extension with evolocumab and the ODYSSEY LONG TERM trial with alirocumab. Expert opinion: In OSLER and ODYSSEY LONG TERM, there were very few cardiovascular outcomes, but the trials do suggest that evolocumab and alirocumab may reduce these outcomes. However, there are also some safety concerns with both of these antibodies. Large clinical outcome trials are underway with both evolocumab and alirocumab, which will probably clarify both the safety concerns and any cardiovascular benefits with these antibodies. In our opinion, these antibodies may be suitable for use in subjects with familial hypercholesterolemia, who are uncontrolled with their present medications, provided intensive safety and cardiovascular monitoring is being undertaken. However, evolocumab and alirocumab should be used with caution in other subjects, until outcome studies in higher numbers of subjects, have shown acceptable safety and cardiovascular profiles.

Genetic variation in tumour necrosis factor and lymphotoxin is not associated with endometriosis in an Australian sample

BACKGROUND Tumour necrosis factor (TNF) is a pleiotropic cytokine with a wide range of immunoregulatory effects. Variation in the promoter region of TNF and the neighbouring lymphotoxin alpha (LTA) gene might be associated with endometriosis. METHODS We examined the association between endometriosis and common single-nucleotide polymorphisms (SNPs) or haplotypes in the TNF/LTA region in an Australian sample by analysing 26 SNPs in 958 endometriosis cases and 959 unrelated controls. We selected functional SNPs in the coding and the promoter region of the TNF gene and HapMap tagging SNPs and typed them on a Sequenom MassARRAY platform. A key SNP (rs1800630) in the promoter region typed in previous studies did not give reliable results. Therefore, we also examined a statistically identical (r(2) = 1) SNP (siSNP) (rs2844482), identified using the web based program ssSNPer. RESULTS Genotype completion rate was 99.5% for SNPs spanning a region of 15.5 kb across the TNF/LTA locus. There was no evidence for association between endometriosis and TNF/LTA SNPs or SNP haplotypes in our case-control study. CONCLUSIONS Our data suggest both TNF and LTA genes are not major susceptibility genes for endometriosis.

The non-pathogenic Australian rabbit calicivirus RCV-A1 provides temporal and partial cross protection to lethal Rabbit Haemorrhagic Disease Virus infection which is not dependent on antibody titres

The endemic non-pathogenic Australian rabbit calicivirus RCV-A1 is known to provide some cross protection to lethal infection with the closely related Rabbit Haemorrhagic Disease Virus (RHDV). Despite its obvious negative impacts on viral biocontrol of introduced European rabbits in Australia, little is known about the extent and mechanisms of this cross protection. In this study 46 rabbits from a colony naturally infected with RCV-A1 were exposed to RHDV. Survival rates and survival times did not correlate with titres of serum antibodies specific to RCV-A1 or cross reacting to RHDV, but were instead influenced by the time between infection with the two viruses, demonstrating for the first time that the cross protection to lethal RHDV infection is transient. These findings are an important step towards a better understanding of the complex interactions of co-occurring pathogenic and non-pathogenic lagoviruses.

Contemplating Knudsen's Baseline: Where small is not so beautiful

Does the Internet's World Wide Web (the web) represent an opportunity or threat to the small firms of the world? In line with recent calls for entrepreneurship research to adopt a more evolutionary approach, this article considers the context, process, and possible outcomes of small place-based firms operating in a web-impacted environment. Despite initial optimism that the web would provide a level-playing field for firms of all sizes, little evidence exist to support such a notion. When the learning abilities deemed necessary to exploit the web are considered, it would seem that only the most entrepreneurial of small firms would likely adapt to web-impacted environments. It is concluded that the present rate of web-based change represents a unique and valuable research opportunity for entrepreneurship researchers.

Mutational analysis of active-site residues in the Mycobacterium leprae RecA intein, a LAGLIDADG homing endonuclease: Asp(122) and Asp(193) are crucial to the double-stranded DNA cleavage activity whereas Asp(218) is not

Mycobacterium leprae recA harbors an in-frame insertion sequence that encodes an intein homing endonuclease (PI-MleI). Most inteins (intein endonucleases) possess two conserved LAGLIDADG (DOD) motifs at their ctive center. A common feature of LAGLIDADG-type homing endonucleases is that they recognize and cleave the same or very similar DNA sequences. However, PI-MleI is distinctive from other members of the family of LAGLIDADG-type HEases for its modular structure with functionally separable domains for DNA-binding and cleavage, each with distinct sequence preferences. Sequence alignment analyses of PI-MleI revealed three putative LAGLIDADG motifs; however, there is conflicting bioinformatics data in regard to their identity and specific location within the intein polypeptide. To resolve this conflict and to determine the active-site residues essential for DNA target site recognition and double-stranded DNA cleavage, we performed site-directed mutagenesis of presumptive catalytic residues in the LAGLIDADG motifs. Analysis of target DNA recognition and kinetic parameters of the wild-type PI-MleI and its variants disclosed that the two amino acid residues, Asp(122) (in Block C) and Asp(193) (in functional Block E), are crucial to the double-stranded DNA endonuclease activity, whereas Asp(218) (in pseudo-Block E) is not. However, despite the reduced catalytic activity, the PI-MleI variants, like the wild-type PI-MleI, generated a footprint of the same length around the insertion site. The D122T variant showed significantly reduced catalytic activity, and D122A and D193A mutations although failed to affect their DNA-binding affinities, but abolished the double-stranded DNA cleavage activity. On the other hand, D122C variant showed approximately twofold higher double-stranded DNA cleavage activity, compared with the wild-type PI-MleI. These results provide compelling evidence that Asp(122) and Asp(193) in DOD motif I and II, respectively, are bona fide active-site residues essential for DNA cleavage activity. The implications of these results are discussed in this report.

Language is, language is not

���Language is, Language is not��� is an installation comprising wall drawings, a fabric drawing prosthetic, performance and digital video. This work investigates ���redrawing��� as a revisionist feminist strategy, taking as it���s starting point Mel Bochner���s work ���Language is not Transparent��� (1970). 'Language is, Language is not' functions as both homage and critique, drawing on the legacy of conceptual art and questioning the engendering of language that it implies. This work was developed and presented for Bus Projects, Melbourne in 2012, and subsequent versions exhibited at Screen Space, Melbourne and Metro Arts Galleries, Brisbane.
