This paper takes a systematic review methodology to unearth the reason for a slow adoption of cloud computing by businesses, despite the user interests and cloud advancements gained recently. The key finding is that the IT industry has taken different modelling approaches to engineer and deliver the cloud services based on the goals of different key cloud players, thereby raising various adoption challenges and concerns. In this context, there is a need for rethinking Software Engineering concepts. This motivates us to question whether the existing Software Engineering theories and modelling principles are sufficient for the new cloud computing paradigm. Due to the paucity of a comprehensive review in literature, the main aim of this review article is to identify such research gaps and insufficiencies in Software Engineering, and to provide recommendations for bridging these gaps. In this work, the systemic review of the state of the art of cloud computing has resulted in identifying four major cloud modelling gaps that require prime attention. The paper discusses these gaps and identifies the key Software Engineering challenges prevalent in addressing each of these gaps. Finally, the author proposes five topmost research recommendations specifically designed for overcoming these gaps/ challenges in order to facilitate a sustainable cloud adoption. Overall, the author's findings have established the need to rethink Software Engineering theories for arriving at a multilateral or distributed cloud modelling approach. With such rethinking, the proposed cloud design automatically incorporates cloud user-roles, interoperability, intelligent automation and trusted cloud infrastructure strategies for achieving a sustainable cloud framework of the future.

Background and Aims Proton nuclear magnetic resonance spectroscopy coupled multivariate analysis (1H NMRPCA/ PLS-DA) is an important tool for the discrimination of wine products. Although 1H NMR has been shown to discriminate wines of different cultivars, a grape genetic component of the discrimination has been inferred only from discrimination of cultivars of undefined genetic homology and in the presence of many confounding environmental factors. We aimed to confirm the influence of grape genotypes in the absence of those factors. Methods and Results We applied 1H NMR-PCA/PLS-DA and hierarchical cluster analysis (HCA) to wines from five, variously genetically-related grapevine (V. vinifera) cultivars; all grown similarly on the same site and vinified similarly. We also compared the semi-quantitative profiles of the discriminant metabolites of each cultivar with previously reported chemical analyses. The cultivars were clearly distinguishable and there was a general correlation between their grouping and their genetic homology as revealed by recent genomic studies. Between cultivars, the relative amounts of several of the cultivar-related discriminant metabolites conformed closely with reported chemical analyses. Conclusions Differences in grape-derived metabolites associated with genetic differences alone are a major source of 1H NMR-based discrimination of wines and 1H NMR has the capacity to discriminate between very closely related cultivars. Significance of the Study The study confirms that genetic variation among grape cultivars alone can account for the discrimination of wine by 1H NMR-PCA/PLS and indicates that 1H NMR spectra of wine of single grape cultivars may in future be used in tandem with hierarchical cluster analysis to elucidate genetic lineages and metabolomic relations of grapevine cultivars. In the absence of genetic information, for example, where predecessor varieties are no longer extant, this may be a particularly useful approach. © 2015 Hu et al.

Background: Clinical activities that trainees can be trusted to perform with minimal or no supervision have been labelled as Entrustable Professional Activities (EPAs). We sought to examine what activities could be entrusted to psychiatry trainees in their first year of specialist training. Methods. We conducted an online survey of Fellows of the Royal Australian and New Zealand College of Psychiatrists (RANZCP). Results: The majority of respondents considered initiating patients with the common medications, discharging patient suffering from schizophrenia, bipolar disorder or following a crisis admission, conducting risk assessments and managing psychiatric emergencies were activities that trainees could be entrusted with by the end of the first stage of training. Conclusions: Four activities were identified that trainees should be entrusted with by the end of their first year of training. Each of these activities comprises a set of competencies in each of the CanMEDS roles. When a trainee is unable to satisfactorily perform an EPA, deficits in the underpinning competencies can be a focus for remediation. Further EPAs are being identified in areas of more specialised practice for use within more advanced training. © 2011 Boyce et al; licensee BioMed Central Ltd. Source

An increasing shortage of crude oil has necessitated into alternative energy sources. In Australia, inappropriate agricultural practices have left large areas of agricultural land subject to secondary salinisation from rising water tables. Opportunities have arisen from groundwater interception schemes for the aquacultural production of marine microalgae far inland from coastal areas where a shortage of suitable sites and strict environmental regulations makes the production of large volumes of microalgae unrealistic. Four small-scale laboratory experiments were undertaken to determine the potential growth of the two species of marine microalgae, Isochrysis galbana Parke and Tetraselmis suecica Stein, in inland saline ground water sourced from a ground water monitoring bore in rural Victoria. The results showed that at the termination of the experiments the differences between experimental units and control treatments of I. galbana and T. suecica with and without algal growth nutrient were not significantly different. © Begell House Inc., 2012.

The Bachelor of Enterprise Learning is a newly accredited undergraduate degree where connectivist principles have been used to guide design of active, student-centered learning activities. A key feature of the curriculum is that it incorporates technology as both a source of information and a tool. Examples from this course are provided in this article showing how connectivist principles can be put into practice in developing learning activities, assessment tasks, and whole subjects. These examples illustrate the value of using a framework such as this for providing consistency in subject design while still leaving scope for innovative and effective pedagogy. They also provide curriculum designers and instructors with practical examples and advice useful for the design and delivery of courses based on a connectivist approach. © Taylor & Francis Group, LLC.
