The architecture of the High Performance Storage System (HPSS)

The rapid growth in the size of datasets has caused a serious imbalance in I/O and storage system performance and functionality relative to application requirements and the capabilities of other system components. The High Performance Storage System (HPSS) is a scalable, next-generation storage system that will meet the functionality and performance requirements or large-scale scientific and commercial computing environments. Our goal is to improve the performance and capacity of storage by two orders of magnitude or more over what is available in the general or mass marketplace today. We are also providing corresponding improvements in architecture and functionality. This paper describes the architecture and functionality of HPSS

Replicating Lean Six Sigma Green Belt Education

Purpose – This paper describes the intricates and possibilities of replicating a Lean Six Sigma Green Belt (LSSGB) education model from a pilot program to other universities—employing ‘replication as strategy’—based on a validated ‘business model.’ Study design/methodology/approach – This work is grounded in a case study on the ESTIEM LSSGB educational method and draws on the replication literature. Specifically: (1) replication as strategy (Winter and Szulanski, 2001) to replicate stimulating learning environments, and (2) replicating sets of teaching practices (Baden-Fuller and Winter, 2007). These theories are practiced using data obtained from various sources: Participant-observer data, interview data, and secondary case data. Findings – To replicate this educational program, a thorough understanding of the ‘business model’ of the LSSGB course is required. This includes a clear understanding of what is valued in each local environment, what configurations of practices create such value, and what environments contain the inputs that stimulate such value creation. Moreover, the replicating speed is substantially affected by the replicators’ knowledge on recognizing course locations for replication and successfully implementing a new course with a suitable configuration. In conclusion, replication of teaching practices between courses is mediated by predefined high-quality course content. Originality/value – The LSSGB course in ESTIEM shows how blended learning opportunities can be configured to deliver impact on a European scale. Decomposing a course to teaching practices and analyzing their inputs identifies the environmental requirements for a course.

Theoretical perspectives in purchasing and supply chain management: an analysis of the literature

The research presented in this paper is work-in-progress and aims to investigate to what extent purchasing and supply chain management (SCM), as a relatively new area of academic enquiry, is ready or able to join the select group of modern scientific disciplines. The analysis indicates that the discipline lacks coherence and exhibits significant and increasingly interdisciplinary breath and is some way off becoming a natural science. Furthermore, it is argued that SCM research has diverse agendas and therefore it is unlikely that one dominant paradigm will emerge.N/

Land clearing in Queensland triples after policy ping pong

[Extract] In 2013, a group of 26 senior scientists in Queensland (including ourselves) expressed serious concern that proposed changes to vegetation protection laws would mean a return to large-scale land clearing. The loss of these protections followed a Ministerial announcement in early 2012 that investigations into and prosecutions of illegal clearing would be halted

Who lives in a pear tree under the sea? A first look at tree reefs as a complex natural biodegradable structure to enhance biodiversity in marine systems

Hard substrates play an important role in global marine systems as settlement surface for sessile reef-forming species such as corals, seaweeds, and shellfish. In soft-sediment systems, natural hard substrates such as stones, bedrock and driftwood are essential as they support diverse assemblages of reef-associated species. However, availability of these hard substrates has been declining in many estuaries and shallow seas worldwide due to human impacts. This is also the case in the Dutch Wadden Sea, where natural hard substrates have gradually disappeared due to burial by sand and/or active removal by humans. In addition, driftwood that was historically imported from rivers has been nullified by upstream logging and coastal damming of estuaries. To investigate the historic ecological role of wood presence in the Wadden Sea as settlement substrate and fish habitat, we constructed three meter high artificial reefs made of felled pear trees. Results demonstrate that these reefs rapidly developed into hotspots of biodiversity. Within six months, the tree-reefs were colonized by sessile hard substrate associated species, with a clear vertical zonation of the settled species. Macroalgae and barnacles were more abundant on the lower parts of the reef, while bryozoans were more dominant on the upper branches. In addition, six fish species were observed on the reefs, while only two species were caught on sandy control sites. Moreover, the abundance of fish on the reefs was five times higher. Individuals of the most commonly caught species, the five-bearded rockling Ciliata mustela, were also larger on the reef. These patterns also hold true for common prawn, Palaemon serratus, which were also larger and ten times more numerous on the reefs. Present findings indicate that the reintroduction of tree-reefs as biodegradable, structurally complex hard substrates can increase local marine biodiversity in soft-sediment systems within relatively short time scales.</p
