Polaroid Type 667 And An Alternative Sabattier Technique, Andrew Davidhazy

Articles

The Sabattier effect has seen a resurgence of interest due to the discovery that Polaroid Type 55 material can be used to achieve it. In this article the application of a less well known material, Polaroid Type 57 or 667 is demonstrated to be equally or even more suited to the task when coupled with modern digital image management techniques.

Instruction Via Chat: Does Co-Browse Help?, Stephanie J. Graves, Christina M. Desai

Articles

Purpose – The purpose of this research is to determine whether instruction would be welcomed by instant messaging (IM)/chat users, whether instruction is possible in this medium, whether it can be effectively provided, and if the use of co-browsing enhances learning.

Design/methodology/approach – Two studies were conducted in which IM/chat reference transcripts were analyzed and patron surveys collected. This research paper compares results from these studies, the first based on use of text-only IM software, the second using commercial chat software with a co-browse feature.

Findings – Findings indicate that patrons welcome instruction, whether they ask for it or not, …

Mapping The Literature Of Medical-Surgical Nursing, Mary K. Taylor

Articles

Background: Medical-surgical or adult health nursing is a complex specialty that requires a wide-ranging literature to inform its research and practice. Several excellent qualitative aids exist for collection development for this field, but quantitative studies are few. While one bibliometric study of journals exists, no recent work had been done in this area.

Method: The Mapping the Literature of Nursing Project protocol was used. Four source journals were selected, and a citation analysis of articles from 1996 to 1998 was conducted.

Results: A list of the most frequently cited journals was created, using Bradford’s Law of Scattering. The list demonstrates …

Age Concern: The Future Of The Oecd, Richard Woodward

Articles

‘Life’, so the adage has it, ‘begins at 40’. But, as American journalist Helen Rowland wryly observed, ‘so do fallen arches, rheumatism, faulty eyesight, and the tendency to tell a story to the same person, three or four times’. Such a sentiment should resonate within the Parisian corridors of the Organisation for Cooperation and Development (OECD) which celebrates its 45th anniversary on 30 September. Rival institutional developments, evolving geo-political realities, hostility from non-governmental organisations (NGOs) and the absence of a precisely defined mission statement have marred the OECD’s fifth decade and left the organisation struggling to justify its place in …

After Autonomy, Carl E. Schneider

Articles

Bioethicists today are like Bolsheviks on the death of Lenin. They have, rather to their surprise, won the day. Their principle of autonomy is dogma. Their era of charismatic leadership is over. Their work of Weberian rationalization, of institutionalizing principle and party, has begun. The liturgy is reverently recited, but the vitality of Lenin's "What Is To Be Done?" has yielded to the vacuity of Stalin's "The Foundations of Leninism." Effort once lavished on expounding ideology is now devoted to establishing associations, organizing degree programs, installing bioethicist commissars in every hospital, and staffing IRB soviets. Not-so-secret police prowl the libraries …

Lossless Compression Of Color Palette Images With One-Dimensional Techniques, Ziya Arnavut, Ferat Sahin

Articles

Palette images are widely used on the World Wide Web (WWW) and in game-cartridge applications. Many images used on the WWW are stored and transmitted after they are compressed losslessly with the standard graphics interchange format (GIF), or portable network graphics (PNG). Well-known 2-D compression schemes, such as JPEG-LS and JPEG-2000, fail to yield better compression than GIF or PNG due to the fact that the pixel values represent indices that point to color values in a look-up table. To improve the compression performance of JPEG-LS and JPEG-2000 techniques, several researchers have proposed various reindexing algorithms. We investigate various compression …

Streaming Motions Toward The Supermassive Black Hole In Ngc 1097, Kambiz Fathi, Thaisa Storchi-Bergmann, Rogemar A. Riffel, Claudia Winge, David J. Axon, Andew Robinson, Alessandro Marconi

Articles

We have used GMOS-IFU and high resolution HST-ACS observations to map, in unprecedented detail, the gas velocity field and structure within the 0.7 kpc circumnuclear ring of the SBb LINER/Seyfert 1 galaxy NGC 1097. We find clear evidence of radial streaming motions associated with spiral structures leading to the unresolved (< 3.5 parsecs) nucleus, which we interpret as part of the fueling chain by which gas is transported to the nuclear starburst and supermassive black hole.

Articles

We present new HST/STIS observations of Centaurus A. [SIII] 9533A was used to study the kinematics in the nuclear region with a 0.1" spatial resolution. The STIS data and the VLT/ISAAC spectra by Marconi et al. (2001) provide independent and consistent measures of the BH mass, which are in agreement with our previous estimate based on the ISAAC data alone: MBH=(1.1+/-0.1) 10^8 Msun for a disk inclination of i=25deg or or MBH=(6.5+/-0.7) 10^7 Msun for i=35deg, the largest i value allowed by the data. We find that the choice of the intrinsic surface brightness distribution, a crucial element in the …

The Acs Virgo Cluster Survey Ix: The Color Distributions Of Globular Cluster Systems In Early-Type Galaxies, Eric Peng, Andres Jordan, Patrick Cote

Articles

We present the color distributions of globular cluster (GC) systems for 100 Virgo cluster earlytype galaxies observed in the ACS Virgo Cluster Survey, the deepest and most homogeneous survey of this kind to date. While the color distributions of individual GC systems can show significant variations from one another, their general properties are consistent with continuous trends across galaxy luminosity, color, and stellar mass. On average, galaxies at all luminosities in our study (−22 < MB < −15) appear to have bimodal or asymmetric GC color distributions. Almost all galaxies possess a component of metal-poor GCs, with the average fraction of metal-rich GCs ranging from 15 to 60%. The colors of both subpopulations correlate with host galaxy luminosity and color, with the red GCs having a steeper slope. The steeper correlation seen in the mean color of the entire GC system is driven by the increasing fraction of metal-rich GCs for more luminous galaxies. To convert color to metallicity, we also introduce a preliminary (g–z)-[Fe/H] relation calibrated to Galactic, M49 and M87 GCs. This relation is nonlinear with a steeper slope for [Fe/H] . −0.8. As a result, the metallicities of the metal-poor and metal-rich GCs vary similarly with respect to galaxy luminosity and stellar mass, with relations of [Fe/H]MP ∝ L0.16±0.04 ∝ M0.17±0.04 ⋆ and [Fe/H]MR ∝ L0.26±0.03 ∝ M0.22±0.03 ⋆ , respectively. Although these relations are shallower than the mass-metallicity relation predicted by wind models and observed for dwarf galaxies, they are very similar to the mass-metallicity relation for star forming galaxies in the same mass range. The offset between the two GC populations varies slowly (∝ M0.05 ⋆ ) and is approximately 1 dex across three orders of magnitude in mass, suggesting a nearly universal amount of enrichment between the formation of the two populations of GCs. We also find that although the metal-rich GCs show a larger dispersion in color, it is the metal-poor GCs that have an equal or larger dispersion in metallicity. The similarity in the M⋆–[Fe/H] relations for the two populations, implies that the conditions of GC formation for metal-poor and metal-rich GCs could not have been too different. Like the color-magnitude relation, these relations derived from globular clusters present stringent constraints on the formation and evolution of early-type galaxies.
