Abstract

Institutional repositories (IRs) have been developed and promoted primarily as a means to re-publish scholarly content previously published elsewhere—usually in journals, festschriften, or collections of articles. This essay discusses the use of IRs as the originating publisher of materials not previously published elsewhere and assesses their potential use as a viable “first resort” for scholarly publication and an already existing alternative to traditional commercial or university presses.     

Editor's Notes

Two examples are given that illustrate the Gauss–Markov theorem. The examples will help students appreciate the use of the word best in connection with the term BLUE (best linear unbiased estimator). The examples will also provide several instructive exercises.     

基于功能视角的高校机构知识库建设策略探索

Biosphere Model for High Level Waste Repository

Method for environmental impact modeling involving uncertainty, overcoming the disadvantage of providing only one upper bound based on accumulated effects from all extreme events. This method provides a suite of upper and lower bounds based on any subset of such extreme events, to be chosen among by the decision maker.     

Electronic journals and the paradigm shift: 1995 Spring forum of the Canadian Serials Industry Systems Advisory Committee

Abstract

Since 2006, Research Online, the University of Wollongong's open access institutional repository has utilised Bepress' Digital Commons software to make available published research outputs and digital theses. This article discusses the outcomes of recent academic demand for its use as a publishing tool of university journals and conference proceedings. The Journal of University Teaching and Learning Practice is provided as an example. Digital Commons includes the editorial management software, EdiKit, which assists in managing submissions, editorial functions, and peer review. Also considered are changes to scholarly communication patterns arising out of the new open access, electronic only, publication regimes.     

A Decision Theory Perspective on the Disposal of High-Level Radioactive Waste

In this paper the problem of high-level nuclear waste disposal is viewed as a five-stage, cascaded decision problem. The first four of these decisions having essentially been made, the work of recent years has been focused on the fifth stage, which concerns specifics of the repository design. The probabilistic performance assessment (PPA) work is viewed as the outcome prediction for this stage, and the site characterization work as the information gathering option. This brief examination of the proposed Yucca Mountain repository through a decision analysis framework resulted in three conclusions: (1) A decision theory approach to the process of selecting and characterizing Yucca Mountain would enhance public understanding of the issues and solutions to high-level waste management; (2) engineered systems are an attractive alternative to offset uncertainties in the containment capability of the natural setting and should receive greater emphasis in the design of the repository; and (3) a strategy of waste management should be adopted, as opposed to waste disposal, as it allows for incremental confirmation and confidence building of a permanent solution to the high-level waste problem.

Research Online: Digital Commons as a Publishing Platform at the University of Wollongong, Australia

Since 2006, Research Online, the University of Wollongong's open access institutional repository has utilised Bepress' Digital Commons software to make available published research outputs and digital theses.

A standard-based business repository for on-demand manufacturing execution systems

In manufacturing execution system (MES) projects, knowledge is heterogeneous and is applied partially in each software package. Consistency is therefore critical. Some standard business reference models exist, such as the IEC/ISO 62264 standard for MESs (also known as ISA S95), or the Supply Chain Operations Reference model for supply chain planning (SCP) and execution (SCE). These reference models have some overlaps. For example, traceability is part of both MES and SCE packages. A consortium of manufacturing software editors for industry has launched an ‘MES on demand’ platform using services from different packages. This paper presents the enriched business repository model built to facilitate business heterogeneity. It is used to align different business repositories (B–B alignment) and different business and software packages (B–S alignment). It likewise serves to align customer requirements with the repository (B–C alignment). The consortium platform is then ‘S95 compliant’ when knowledge supported by the different actors is included.     

Improbability of Igneous Intrusion Promoting a Critical Event in Spent Nuclear Fuel Disposed in Unsaturated Tuff

In their regulations, the U.S. Environmental Protection Agency and the U.S. Nuclear Regulatory Commission permit the omission of features, events, or processes with probabilities of <10(-4) in 10(4) yr (e.g., a constant frequency of <10(-8) per yr) in assessments of the performance of radioactive waste disposal systems. Igneous intrusion (or "volcanism") of a geologic repository at Yucca Mountain for radioactive waste is one disruptive event that has a probability with a range of uncertainty that straddles this regulatory criterion and is considered directly in performance assessment calculations. A self-sustained nuclear chain reaction (or "criticality") is another potentially disruptive event to consider, although it was never found to be important when evaluating the efficacy of radioactive waste disposal since the early 1970s. The thesis of this article is that the consideration of the joint event--volcanism and criticality--occurring in any 10,000-year period following closure can be eliminated from performance calculations at Yucca Mountain. The probability of the joint event must be less than the fairly well-accepted but low probability of volcanism. Furthermore, volcanism does not "remove" or "fail" existing hydrologic or geochemical constraints at Yucca Mountain that tend to prevent concentration of fissile material. Prior to general corrosion failure of waste packages, the mean release of fissile mass caused by a low-probability, igneous intrusive event is so small that the probability of a critical event is remote, even for highly enriched spent nuclear fuel owned by the U.S. Department of Energy. After widespread failure of packages occurs, the probability of the joint event is less than the probability of criticality because of the very small influence of volcanism on the mean fissile mass release. Hence, volcanism plays an insignificant role in inducing criticality over any 10(4)-yr period. We also argue that the Oklo reactors serve as a natural analogue and provide a rough bound on probability of criticality given favorable hydrologic or geochemical conditions on the scale of the repository that is less than 0.10. Because the product of this bound with the probability of volcanism represents the probability of the joint event and the product is less than 10(-4) in 10(4) yr, consideration of the joint event can be eliminated from performance calculations.
