The Role of Evidence in Establishing Trust in Repositories
No full textThis article arises from work by the Digital Curation Centre (DCC) Working Group examining mechanisms to roll out audit and certification services for digital repositories in the United Kingdom. Our attempt to develop a program for applying audit and certification processes and tools took as its starting point the RLG-NARA Audit Checklist for Certifying Digital Repositories. Our intention was to appraise critically the checklist and conceive a means of applying its mechanics within a diverse range of repository environments. We were struck by the realization that while a great deal of effort has been invested in determining the characteristics of a 'trusted digital repository', far less effort has concentrated on the ways in which the presence of the attributes can be demonstrated and their qualities measured. With this in mind we sought to explore the role of evidence within the certification process, and to identify examples of the types of evidence (e.g., documentary, observational, and testimonial) that might be desirable during the course of a repository audit.
Age, geographical distribution and taphonomy of an unusual occurrence of mummified crabeater seals on James Ross Island, Antarctica
No full textAn unusually dense collection of some 150 dead crabeater seals (Family Phocidae), in various stages of decay, occurs in the Brandy Bay hinterland, north-western James Ross Island, northern Antarctic Peninsula. Throughout the past 100 years, the presence of shelf ice (no longer present today) and sea ice in Prince Gustav Channel, between James Ross Island and the Antarctic Peninsula, has prevented seals from readily accessing the western side of James Ross Island. However, open water pools, some over one kilometre in diameter, remain accessible throughout the winter months, allowing seals to haul out onto the ice. It is likely that some of these seals may become disorientated as they wander away from the pools and instead head toward Brandy Bay and onto low-lying and snow-covered Abernethy Flats, easily mistaken for sea ice in early winter, where they perish. The large number of variably-decayed animals present suggests that this has probably happened on numerous occasions. However, some of the dead seals also probably perished during a documented mass dying event of crabeater seals in Prince Gustav Channel caused by an unidentified epidemic, possibly phocine distemper virus (PDV), during the spring of 1955
Composition and distribution of the peracarid crustacean fauna along a latitudinal transect off Victoria Land (Ross Sea, Antarctica) with special emphasis on the Cumacea
No full textThe following study was the first to describe composition and structure of the peracarid fauna systematically along a latitudinal transect off Victoria Land (Ross Sea, Antarctica). During the 19th Antarctic expedition of the Italian research vessel “Italica” in February 2004, macrobenthic samples were collected by means of a Rauschert dredge with a mesh size of 500 m at depths between 85 and 515 m. The composition of peracarid crustaceans, especially Cumacea was investigated. Peracarida contributed 63% to the total abundance of the fauna. The peracarid samples were dominated by amphipods (66%), whereas cumaceans were represented with 7%. Previously, only 13 cumacean species were known, now the number of species recorded from the Ross Sea increased to 34. Thus, the cumacean fauna of the Ross Sea, which was regarded as the poorest in terms of species richness, has to be considered as equivalent to that of other high Antarctic areas. Most important cumacean families concerning abundance and species richness were Leuconidae, Nannastacidae, and Diastylidae. Cumacean diversity was lowest at the northernmost area (Cape Adare). At the area off Coulman Island, which is characterized by muddy sediment, diversity was highest. Diversity and species number were higher at the deeper stations and abundance increased with latitude. A review of the bathymetric distribution of the Cumacea from the Ross Sea reveals that most species distribute across the Antarctic continental shelf and slope. So far, only few deep-sea records justify the assumption of a shallow-water–deep-sea relationship in some species of Ross Sea Cumacea, which is discussed from an evolutionary point of view
Retreat from Boothia: The Original Diary of James Clark Ross, May to October 1832
No full textFollowing the abandonment of John Ross\u27s expedition ship Victory in Lord Mayor Bay in 1832, Ross\u27s nephew and second-in-command, James Clark Ross, led a separate forward sledging group for much of the retreat to Somerset Island. While John Ross described the events of his own sledging group in his published narrative, he provided essentially no information on James Clark Ross\u27s group. Recently, the journal kept by James Clark Ross during the retreat was located, and it forms the subject of this article. The journal covers the period from 4 May to 14 October 1832, during which the Victory was abandoned, an attempt (eventually aborted) made to escape using sledges and boats via Port Leopold, and preparations made to spend the winter of 1832-33 at Fury Beach.Key words: James Clark Ross, Boothia Peninsula and Somerset Island, 1832, unpublished diary, arctic explorationRÉSUMÉ. À la suite de l’abandon dans la baie Lord Mayor du navire Victory transportant l’expédition de John Ross en 1832, le neveu et commandant adjoint de Ross, James Clark Ross, dirigea un groupe séparé, équipé de traîneaux pendant la plus grande partie de sa retraite vers l’île Somerset. Si, dans le récit publié, John Ross relate ce qui est arrivé à son propre groupe voyageant aussi en traîneau, il n’a pratiquement pas fait mention du groupe de James Clark Ross. Le journal tenu par ce dernier au cours de la retraite a été découvert récemment et il constitue le sujet de cet article. Le journal couvre la période allant du 4 mai au 14 octobre 1832, durant laquelle le Victory fut abandonné, une tentative (qui finalement échoua) fut entreprise en vue d’atteindre Port Leopold en traîneau et en bateau, et des préparatifs furent menés pour passer l’hiver de 1832-1833 à Fury Beach.Mots clés: James Clark Ross, péninsule de Boothia et île Somerset, 1832, journal inédit, exploration arctiqu

Understanding 1968: the case of Brest
No full textThis article examines the dominance of Paris in how May '68 has been portrayed over the years. It will be argued, through a case-study of the revolt in the Breton city of Brest, that the Paris-centred approach is one that belies the true nationwide aspect of May/June 1968. As one of a range of characteristics, the concentration on the Latin Quarter has helped mould what Kristin Ross has described as the 'official history' of 1968. An examination of how the events were played out within different regional contexts would go a long way towards helping overcome the shortcomings of the increasingly narrow portrayal that has come to dominate the stereotypical image of 1968

Simulation of thermal plant optimization and hydraulic aspects of thermal distribution loops for large campuses
No full textFollowing an introduction, the author describes Texas A&M University and its utilities system. After that, the author presents how to construct simulation models for chilled water and heating hot water distribution systems. The simulation model was used in a $2.3 million Ross Street chilled water pipe replacement project at Texas A&M University. A second project conducted at the University of Texas at San Antonio was used as an example to demonstrate how to identify and design an optimal distribution system by using a simulation model. The author found that the minor losses of these closed loop thermal distribution systems are significantly higher than potable water distribution systems. In the second part of the report, the author presents the latest development of software called the Plant Optimization Program, which can simulate cogeneration plant operation, estimate its operation cost and provide optimized operation suggestions. The author also developed detailed simulation models for a gas turbine and heat recovery steam generator and identified significant potential savings. Finally, the author also used a steam turbine as an example to present a multi-regression method on constructing simulation models by using basic statistics and optimization algorithms. This report presents a survey of the author??s working experience at the Energy Systems Laboratory (ESL) at Texas A&M University during the period of January 2002 through March 2004. The purpose of the above work was to allow the author to become familiar with the practice of engineering. The result is that the author knows how to complete a project from start to finish and understands how both technical and nontechnical aspects of a project need to be considered in order to ensure a quality deliverable and bring a project to successful completion. This report concludes that the objectives of the internship were successfully accomplished and that the requirements for the degree of Degree of Engineering have been satisfied
Induction of programmed cell death in mammalian cells by isolates of Ross River virus
No full textArthritogenic alphaviruses, such as Ross River virus (RRV) are associated with worldwide outbreaks of human polyarthritis/arthralgia. The pathogenesis of RRV and other alphaviruses is poorly understood. Studies have shown potential links between the different strains of RRV and variation in their pathogenesis and virulence. Currently there is believed to be two circulating strains of RRV, the south western (SW) from the south west region of Western Australia and the north eastern (NE) from the east coast of Australia. Studies have suggested that the persistence of RRV may be the result of an impaired immune response. This study was designed to determine if the SW and NE isolates of RRV have the ability to induce apoptosis in DCs and fibroblasts and discover any possible variation in their apoptosis-inducing capacity. Both Vero cells and murine bone marrow DCs (BMDCs) were infected with the SW74249 (SW) and SW82627 (NE) strains of RRV. A time course analysis of two apoptotic markers and a cell viability marker for both cell types was conducted by flow cytometry. The results indicate RRV- induced apoptosis in both Vero cells and BMDCs, with RRV inducing a stronger pro-apoptotic response in BMDCs than Vero cells, 24 h after infection. Between the two strains there was little variation in the Vero cells over time. In the BMDCs there was some variation with the RRV-SW strain inducing a higher percentage of cell death than the RRV-NE strain, 24 h after infection. Collectively, the data indicates that RRV has the capacity to induce a pro-apoptotic response in DCs, with the SW presenting as more aggressive compared to the NE, potentially leading to greater virulence. This data could help to explain the mechanism of RRV persistence in vertebrate hosts, as well as the reported differences in severity and duration of human clinical symptoms. Immunotherapy aimed at correcting the patient’s dysfunctional immune system, may represent a new strategy for the successful medical treatment of RRV infection
