DSpace How-To Guide: Tips and tricks for managing common DSpace chores

This short booklet is intended to introduce the commonest non-obvious customization-related tasks for newcomers to DSpace administration. It has been written against the current stable version 1.3.2 of DSpace. We have tried to include instructions for different operating systems as required; most customizations, however, work identically cross-platform. This booklet was created as a handout for the tutorial "Making DSpace Your Own", at the Joint Conference on Digital Libraries (JCDL) 2006 in Chapel Hill, North Carolina.unpublishednot peer reviewe

The First Record of Raillietina (Raillietina) celebensis (Janicki, 1902), (Cestoda) in Man from Australia, with a Critical Survey of Previous Cases

Gravid proglottides of Raillietina (R.) celebensis (Janicki) are reported from a child in Brisbane, Queensland. Complete tapeworms of the same species are reported from Rattus assimilis Gould, from Mt. Glorious, South Queensland. A critical survey is made of all the cases previously recorded from man. Raillietina (R.) madagascariensis is for the present, regarded as a species sub judice. Raillietina (R.) demerariensis var. trinitatae Cameron & Reesal, 1951 has been raised to specific rank and named R. (R.) trinitatae (Cameron & Reesal, 1951) nov.comb. The synonyms of R. (R.) celebensis; R. (R.) demarariensis; R. (R.) alouattae and R. (R.) trinitatae, are discusse

The invariant charges of the Nambu-Goto String and Canonical Quantization

It is shown that the algebra of diffeomorphism-invariant charges of the Nambu-Goto string cannot be quantized in the framework of canonical quantization. The argument is shown to be independent of the dimension of the underlying Minkowski space.Comment: v2: reference adde

Freshwater balance and the sources of deep and bottom waters in the Arctic Ocean inferred from the distribution of H218O

Data from sections across the Eurasian Basin of the Arctic Ocean occupied in 1987 and 1991 are used to derive information on the freshwater balance of the Arctic Ocean and on sources of the deep waters of the Nansen, Amundsen and Makarov basins. Using salinity, H218O, and mass balances we estimate the river-runoff and the sea-ice melt water fractions contained in the upper waters of the Arctic Ocean and infer pathways of the river-runoff signal from the shelf seas across the central Arctic Ocean to Fram Strait. The average mean residence time of the river-runoff fraction contained in the Arctic Ocean halocline is determined to be about 11 to 14 years. Pacific water entering through Bering Strait is traced using silicate and its influence on the halocline waters of the Canadian Basin is estimated. Water column inventories of river-runoff and sea-ice melt water are calculated for a section just north of Fram Strait and implications of these inventories for sea-ice export through Fram Strait are discussed. Comparison of the ratios of shelf water, Atlantic water and the deep waters of the Arctic Ocean indicate that the sources of the deep and bottom waters of the Eurasian Basin are located in the Barents and Kara seas

An aeroponic culture system for the study of root herbivory on Arabidopsis thaliana

<p>Abstract</p> <p>Background</p> <p>Plant defense against herbivory has been studied primarily in aerial tissues. However, complex defense mechanisms have evolved in all parts of the plant to combat herbivore attack and these mechanisms are likely to differ in the aerial and subterranean environment. Research investigating defense responses belowground has been hindered by experimental difficulties associated with the accessibility and quality of root tissue and the lack of bioassays using model plants with altered defense profiles.</p> <p>Results</p> <p>We have developed an aeroponic culture system based on a calcined clay substrate that allows insect herbivores to feed on plant roots while providing easy recovery of the root tissue. The culture method was validated by a root-herbivore system developed for <it>Arabidopsis thaliana </it>and the herbivore <it>Bradysia </it>spp. (fungus gnat)<it>. Arabidopsis </it>root mass obtained from aeroponically grown plants was comparable to that from other culture systems, and the plants were morphologically normal. <it>Bradysia </it>larvae caused considerable root damage resulting in reduced root biomass and water absorption. After feeding on the aeroponically grown root tissue, the larvae pupated and emerged as adults. Root damage of mature plants cultivated in aeroponic substrate was compared to that of <it>Arabidopsis </it>seedlings grown in potting mix. Seedlings were notably more susceptible to <it>Bradysia </it>feeding than mature plants and showed decreased overall growth and survival rates.</p> <p>Conclusions</p> <p>A root-herbivore system consisting of <it>Arabidopsis thaliana </it>and larvae of the opportunistic herbivore <it>Bradysia </it>spp. has been established that mimics herbivory in the rhizosphere. <it>Bradysia </it>infestation of <it>Arabidopsis </it>grown in this culture system significantly affects plant performance. The culture method will allow simple profiling and <it>in vivo </it>functional analysis of root defenses such as chemical defense metabolites that are released in response to belowground insect attack.</p

Bridging the university-school divide - Horizontal expertise and the two-worlds pitfall

Research on teacher learning consistently documents the disjuncture between the practices beginning teachers encounter in university teacher preparation courses and those they reencounter in the K-12 classrooms in which they learn to teach. As preservice teachers enter teaching, they gravitate toward conventional K-12 practices, dismissing those endorsed by the university as impractical. In this article, the authors delineate the concept of horizontal expertise and document how its production and use can address this “two-worlds pitfall.” Drawing on the authors\u27 work creating a cross-institutional collaborative, they identify three processes central to the production of horizontal expertise in teacher education: the exchange of tools, the negotiation of social languages, and argumentation. They then trace its use across the university and school settings to show how horizontal expertise can rescript mentoring and expand dialogic practices in the university. The authors conclude by identifying the challenges of developing horizontal expertise in teacher educatio
