    Full text link
    A machine capable of digitizing two 8 inch by 10 inch (203 mm by 254 mm) glass astrophotographic plates or a single 14 inch by 17 inch (356 mm by 432 mm) plate at a resolution of 11 microns per pixel or 2309 dots per inch (dpi) in 92 seconds is described. The purpose of the machine is to digitize the \~500,000 plate collection of the Harvard College Observatory in a five year time frame. The digitization must meet the requirements for scientific work in astrometry, photometry, and archival preservation of the plates. This paper describes the requirements for and the design of the subsystems of the machine that was developed specifically for this task.Comment: 12 pages, 9 figures, 1 table; presented at SPIE (July, 2006) and published in Proceeding

    85. Cambridge, Trinity College R. 17. 1 (987) "Eadwine Psalter" ("Canterbury Psalter") (with London, British Library, Add. 37472(1) [165a], London, Victoria and Albert Museum 661 [319a], New York, Pierpont Morgan Library, M. 521 and M. 724 [332a]) [Ker 91, Gneuss -) HISTORY: A lavishly illustrated, large-format triple Psalter containing the Gallicanum, Romanum, and Hebraicum versions of the Psalms, with marginal and interlinear glosses to the Gallicanum from the "Glossa Ordinaria" ("parva glosatura"), a continuous interlinear OE gloss to the Romanum, and a continuous interlinear Anglo-Norman (French) gloss to the Hebraicum. Probably written at Christ Church, Canterbury; dated by the script to the 1150s (T. Webber in Gibson et al. 1992: 24). The Psalter receives its common title from the large illustration of the scribe Eadwine on f. 283v, a feature added about twenty years after the Psalter was written. A direct copy of this manuscript was made in the late 12c, now Paris Bibliotheque Nationale lat. 8846 [432]. The Psalter is listed in Henry Eastry's (Prior of Christ Church, 1284- 1331) early 14c inventory of the Christ Church library (London, BL Cotton Galba E. iv, ed. James 1903: 51, no. 323), where it appears as "Tripartitum psalterium Edwini:' As T. A. Heslop notes (in Gibson et al. 1992: 193-94), the earliest direct indication that the codex belonged to the monastic community comes in a partly erased memorandum (f. 4v): 'Istud psalteriu<m> sancte ecc<les>ie Cantuarien<sis> traditu<m> est ad | usum d<omi>ni Thome Archiep(iscop)i eiusdem ecc<les>ie p<er> Priorem | & capit<u>l<u>m eiusdem ad suu<m> beneplacitu<m>. p<er> modu<m> mutui' (facs. in Gibson et al. 1992: pl. 2d; ed. Verfaillie-Markey 1985, who suggests that the Thomas referred to is likely Archbishop Thomas Arundel, 1397, 1399-1414). The "Eadwine Psalter" may still have remained with the archbishops in the mid-16c, as indicated by another, more thoroughly erased, inscription on f. 1r: 'Liber Academie Cantabrigiensis ex dona | Richardi Arkynstall anno d[omi]ni 1584' (ed. Heslop in Gibson et al. 1992: 194; see n. 4, and pls. 2e, f ). Arkinstall, who matriculated at Queen's College, Cambridge, 1584-1585, may have appropriated the codex from Richard Cox, Bishop of Ely (1559-1581 ), when he was a student there (for a discussion of this complex matter, see Heslop in Gibson et al. 1992: 194; see also Keynes 1992: 40 ). The manuscript remained at Canterbury until it was presented to Trinity College by Thomas Nevile, Dean of Canterbury (1597-1615), and Master of Trinity (now the inside pastedown, Nevile's bookplate and label of Trinity College, was formerly on f. 2r, as in the film). Binding is from the 17c (see N. Pickwoad in Gibson et al. 1992: 9). Edited and translated in 1630 by William L'Isle (1569?-1637), one-time fellow of King's College, Cambridge; edition preserved in Oxford, Bodi. Lib. Laud Misc. 201 (see Pulsiano 2000). For a full discussion of the history of the manuscript, see T. A. Heslop and D. McKitterick, as well as M. Gibson in Gibson et al. 1992: 193-213. In all probability the "Eadwine Psalter;' like its counterpart, Paris BN lat. 8846, originally had prefatory picture pages containing Old Testament and Gospel scenes which were removed; they are thought to still exist as four dispersed leaves: New York, Pierpont Morgan Library, M. 521 and M. 724 [332a], London, BL Additional 37472(1) [165a], and London, Victoria and Albert Museum MS 661 [319a]. They were likely removed before the manuscript came to Trinity College in the early 17 c, and may have been removed when the book was bound around the same time, perhaps in London. They appeared in the private collection of William Young Ottely, who sold them in 1838 (for the histories of the individual leaves see their individual descriptions, also G. Henderson in Gibson et al. 1992: 25-42)

    Neuropsychological Outcomes of U.S. Veterans with Report of Remote Blast-Related Concussion and Current Psychopathology

    Get PDF
    This study explored whether remote blast-related MTBI and/or current Axis I psychopathology contribute to neuropsychological outcomes among OEF/OIF veterans with varied combat histories. OEF/OIF veterans underwent structured interviews to evaluate history of blast-related MTBI and psychopathology and were assigned to MTBI (n = 18), Axis I (n = 24), Co-morbid MTBI/Axis I (n = 34), or post-deployment control (n = 28) groups. A main effect for Axis I diagnosis on overall neuropsychological performance was identified (F(3,100) = 4.81; p = .004), with large effect sizes noted for the Axis I only (d = .98) and Co-morbid MTBI/Axis I (d = .95) groups relative to the control group. The latter groups demonstrated primary limitations on measures of learning/memory and processing speed. The MTBI only group demonstrated performances that were not significantly different from the remaining three groups. These findings suggest that a remote history of blast-related MTBI does not contribute to objective cognitive impairment in the late stage of injury. Impairments, when present, are subtle and most likely attributable to PTSD and other psychological conditions. Implications for clinical neuropsychologists and future research are discussed.

    Attractancy of Racemic Disparlure and Certain Analogues to Male Gypsy Moths and the Effect of Trap Placement

    Get PDF
    Traps hung on small trees of 3-8 cm diam and baited with racemic epoxides, hydrocarbons and other analogues related to racemic cis-7,8-epoxy-2-methyloctadecane (disparlure) resulted in male Lymantria dispar L. (gypsy moth) catches statistically indistinguishable from those of unbaited traps. Only (±)-disparlure yielded trap catches statistically above the level of unbaited traps. However, trap placement on trees of ca. 0.5 m diam produced appreciable trap catches, even in unbaited trap

    Formation of disclination lines near a free nematic interface

    We have studied the nucleation and the physical properties of a -1/2 wedge disclination line near the free surface of a confined nematic liquid crystal. The position of the disclination line has been related to the material parameters (elastic constants, anchoring energy and favored anchoring angle of the molecules at the free surface). The use of a planar model for the structure of the director field (whose predictions have been contrasted to those of a fully three-dimensional model) has allowed us to relate the experimentally observed position of the disclination line to the relevant properties of the liquid crystals. In particular, we have been able to observe the collapse of the disclination line due to a temperature-induced anchoring angle transition, which has allowed us to rule out the presence of a real disclination line near the nematic/isotropic front in directional growth experiments. 61.30.Jf,61.30.G

    Problematizing Choice: Responsible consumers and sceptical citizens

    About the book: Governance, Consumers and Citizens is the first book to bring together a study of governance with consumption, examining the changing place of the consumer as citizen in recent trends in governance, the tensions between competing ideas and practices of consumerism and the active role consumers play in the construction and practice of governance. Radically pushing forward the debate on consumers and governance, this collection outlines new conceptions and posits new policy agendas. Bringing together international experts from political science, history, geography, social policy and media studies, this study shows how governance and consumption are intertwined in crucial aspects of public policy and contemporary politics
