A Unicore Globus Interoperability Layer
No full textFor several years, UNICORE and Globus have co-existed as approaches to exploiting what has become known as the "Grid". Both offer many services beneficial for creating and using production Grids. A cooperative approach, providing interoperability between Globus and UNICORE, would result in an advanced set of Grid services that gain strength from each other. This paper outlines some of these parallels and differences as they relate to the development of an interoperability layer between UNICORE and Globus. Given the increasing ubiquity of Globus, what emerges is the desire for a hybridised facility that utilises the UNICORE work-flow management of complex, multi-site tasks, but that can run on either UNICORE- or Globus-enabled resources. The technical challenge in achieving this, addressed in this paper, consists of mapping resource descriptions from both grid environments to an abstract format appropriate to work-flow preparation, and then the instantiation of work-flow tasks on the target systems. Other issues such as reconciling disparate security models and file transfer support are also addressed

No full textNeivamyrmex ndeh, new species Figures 118, 132, 143 DIAGNOSIS Male: head and mesosoma blackish brown, gaster reddish brown; head 1.5 × broader than long measured across eyes; smooth and shiny between scattered small punctures; mesosoma blackish brown, entire surface smooth and shining with numerous scattered small punctures, pilosity suberect and dense. Queen and worker unknown. DESCRIPTION Male, measurements (mm) (n = 2): HW 0.86 - 0.91 (0.91); HL 0.55 - 0.58 (0.58); SL 0.39 - 0.41 (0.41); SW 0.15 - 0.16 (0.15); EL 0.305 - 0.306 (0.305); EW 0.23 - 0.26 (0.23); OD 0.09 - 0.10 (0.09); OOD 0.15 - 0.175 (0.175); OMD 0.07 - 0.12 (0.12); OVD 0.20; PW 0.70 (0.70); ML 0.40 (0.40); PL 0.62 - 0.70 (0.70). Indices: CI 156 - 158 (158); SI 49 - 57 (57). Head almost 1.6 × as broad as long. Dorsal margin, in frontal view, concave and rounded at sides; preoccipital carina weak and not forming distinct collar. Free clypeal margin (ventral margin) slightly concave; frontal carina sharp between antennal fossae, but becoming rounded dorsad and curving laterad to form moderate swelling above antennal fossae. Mandible sickle-shaped and acute at apex, about 0.40 mm long. EL 1.3 × EW. OOD about 1.75 × OD. Scape extending to level of upper eye margin, about 3 × longer than broad; subantennal lamella prominent. Mesosoma smooth and shiny, with numerous scattered small punctures. Petiole slightly longer than broad; posterolateral corners rounded; dorsal surface shiny, ventral surface less so. First three segments of gaster smooth and shiny, following segments duller, more distinctly, finely punctate. Subgenital plate longer than broad, somewhat spatulate; apicolateral teeth prominent, median tooth small. Dorsal margin of paramere broadly triangular, margins densely clothed with long flexuous hairs. Volsella with apical fork, dorsal process large and sharp, ventral process blunt and much shorter; inner margin each segment with a minute denticle near fork; numerous long erect hairs along ventral margin. Aedeagus in profile with apically rounded posterodorsal lobe and slightly longer, out-turned sharply pointed posteroventral lobe. Color: head and mesosoma blackish brown, first two gastral segments similar, following segments becoming reddish brown on posterior segments; wings clear brownish. TYPE MATERIAL (Map 5) Holotype: U. S. A., Arizona, Santa Cruz Co., Yanks Canyon (31.42 ° N111.17 ° W), 12 - 15 Aug. 1993 (B. V. Brown and D. Feener). Paratype: U. S. A., Arizona, Cochise Co., Portal, 4800 ft., 4 Aug. 1959 (H. E. Evans). Both specimens in LACM. ETYMOLOGY This species is named for the Ndeh or Apache people of the southwestern United States and adjacent Mexico; the name pronounced approximately “ in deh ”, accenting the second syllable. DISCUSSION This minute species, currently known only from the two specimens cited above, is close in size only to N. baylori and should be readily identifiable on that basis alone. The holotype was taken in a Malaise trap and the Portal specimen was presumably taken at black light. The worker caste of this distinct species is unknown but is certainly likely to be another minute species; possibly it is N. goyahkla, described above. Neivamyrmex ndeh is superficially similar to N. microps, but is significantly smaller and with distinctive genitalic features: the crotch of the apical fork of the volsella has only two barely perceptible teeth that are well removed from each other (see discussion of N. microps).Published as part of Snelling, G.

Rearticulating historic Fort Snelling : Dakota memory and colonial haunting in the American Midwest
No full texttextBuilt in 1819 by the U.S. government, Fort Snelling sits at the confluence of the Minnesota and Mississippi Rivers. This place is called a “bdote” by the Dakota people. Oral traditions describe bdote as the site of Dakota creation. Treaties in the nineteenth century allowed the U.S. government to dispossess the Dakota of this land. Fort Snelling is connected to many important points in U.S. history. It operated as a military post until the mid-twentieth century, and was a training or processing site for U.S. servicepersons who fought in the Civil War, U.S. Indian removal campaigns, and World War Two, among others. Dred Scott lived as a slave at Fort Snelling. Following the U.S.-Dakota War of 1862, about 1,600 Dakota people were forcibly concentrated below Fort Snelling, where nearly 300 died. Shortly after, the U.S. government banished the Dakota from Minnesota.
Today, Fort Snelling exists as “Historic Fort Snelling.” Run by the Minnesota Historical Society (MHS), the site offers a living history program which interprets Fort Snelling “as it was” in the 1820s—before much of these events of import occurred. This portrayal is geared toward schoolchildren and white Minnesotans, and focuses on the premise of peaceful U.S. settlement in the American West.
This study describes Fort Snelling’s history, and address peoples’—both Dakota and other Minnesotans’—objections to the circumscribed interpretation of history at Historic Fort Snelling. By better revealing the memory alive at this site, most specifically the popularly ignored Dakota memories of Fort Snelling and bdote, this study hopes to convey what scholar Avery F. Gordon would term the “hauntings” present but unacknowledged at Historic Fort Snelling.
This study concludes that in order to express the density of memory at Fort Snelling, MHS and Historic Fort Snelling must acknowledge that the Dakota people and their stories are crucial to its history. Further, these institutions must recognize that oppressive structures like U.S. colonialism allowed for Fort Snelling’s creation and operation. These structures and the hauntings they produce are still alive on this land, and onsite historical interpretation at Historic Fort Snelling must transform to reflect these living memories.American Studie

MeSH term explosion and author rank improve expert recommendations
No full textInformation overload is an often-cited phenomenon that reduces the productivity, efficiency and efficacy of scientists. One challenge for scientists is to find appropriate collaborators in their research. The literature describes various solutions to the problem of expertise location, but most current approaches do not appear to be very suitable for expert recommendations in biomedical research. In this study, we present the development and initial evaluation of a vector space model-based algorithm to calculate researcher similarity using four inputs: 1) MeSH terms of publications; 2) MeSH terms and author rank; 3) exploded MeSH terms; and 4) exploded MeSH terms and author rank. We developed and evaluated the algorithm using a data set of 17,525 authors and their 22,542 papers. On average, our algorithms correctly predicted 2.5 of the top 5/10 coauthors of individual scientists. Exploded MeSH and author rank outperformed all other algorithms in accuracy, followed closely by MeSH and author rank. Our results show that the accuracy of MeSH term-based matching can be enhanced with other metadata such as author rank
