"Some Personal Observations on the Wayne Morse Re-Election Campaign of 1968" memoir
No full textA 32-page memoir by Oregon journalist and author Ron Abell titled "Some Personal Observations on the Wayne Morse Re-Election Campaign of 1968," written in September 2005. In his memoir, Abell detailed his experiences and what he witnessed as a salaried employee of the 1968 Re-Elect Wayne Morse Committee for the US Senate, including the campaign's finances, the primary election, how Vietnam was viewed as a campaign issue, how the press treated the campaign, his perspective of the Bob Packwood campaign, and how the Morse campaign ultimately failed. The Robert "Bobby" Kennedy presidential campaign is notably mentioned.This is one of a collection of digitized objects from the Les AuCoin Papers (MS.147) at the Pacific University Archives. AuCoin served in the Oregon House of Representatives (1971-1975) and in the United States House of Representatives from Oregon's 1st District (1975-1993)
Endangering women's health for profit: health and safety in Mexico's maquiladoras
No full textSince the North American Free Trade Agreement (NAFTA) was agreed, thousands of maquiladoras (assembly plants) have sprung up along the Mexican side of the Mexico/US border. Around a million workers are subject to violations of their human, labour, and health rights, the author argues, and this is a by-product of `free trade'. Abell advocates worker organising, appropriate training and access to information, and international solidarity, in order to avoid such abuses here and in the growing number of export processing zones (EPZs) around the world
Retrieval Performance and Indexing Differences in ABELL and MLAIB
No full textSearches for 117 British authors are compared in the Annual Bibliography of English Language and Literature (ABELL) and the Modern Language Association International Bibliography (MLAIB). Authors are organized by period and genre within the early modern era. The number of records for each author was subdivided by format, language of publication, and number of unique citations, defined as records retrieved in one database but not the other. Each of the unique records in one database was searched in the other to examine indexing differences. Of the unique items in ABELL, 49.1% were due to indexing differences, while indexing differences accounted for 35.4% of the unique records in MLAIB. The indexing differences significantly impacted the retrieval performance of each database

The intracluster light on Frontier Fields clusters Abell 370 and Abell S1063
No full textWe analysed the contribution of the intracluster light (ICL) to the total luminosity of two massive galaxy clusters observed by the Hubble Space Telescope within the Frontier Fields program, Abell 370 (z ∼ 0.375) and Abell S1063 (z ∼ 0.348), in order to correlate it with the dynamical stage of these systems. We applied an algorithm based on the Chebyshev–Fourier functions called CICLE, specially developed to disentangle the ICL from the light of galaxies and measure the ICL fraction. We measured the ICL fraction in three broad-band optical filters, F435W, F606W, and F814W, without assuming any prior hypothesis about the ICL physical properties or morphology. The results obtained from the ICL fraction vary between ∼7−25 per cent, and ∼3−22 per cent for both A370 and AS1063, respectively, which are consistent with theoretical predictions for the total amount of ICL obtained by ICL formation and evolution simulations. We found enhanced ICL fractions in the intermediate filter F606W for both clusters and we suggest that this is due to the presence of an excess of younger/lower metallicity stars in the ICL compared to the cluster galaxies. We conclude that both Abell 370 and Abell S1063 are merging systems since they exhibit a similar feature as merging CLASH and Frontier Fields clusters sub-sample previously analysed. We compare these results to the dynamical indicators obtained through different methods and we reinforce the use of ICL as a new and independent method to determine the dynamical state of clusters of galaxies. © 2022 The Author(s) Published by Oxford University Press on behalf of Royal Astronomical Society.This work has received financial support from Fundação Carlos Chagas Filho de Amparo à Pesquisa do Estado do Rio de Janeiro (FAPERJ, Brazil) under the grant Nota 10 No. E-26/200.953/2019 (242872) and from Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq, Brazil) under the grant No. 141631/2020-1.

The hydrogen-deficient knot of the 'born-again' planetary nebula Abell 58 (V605 Aql)
No full textWe have analysed deep optical spectra of the 'born-again' planetary nebula Abell 58 and its hydrogen-deficient knot, surrounding V605 Aql, which underwent a nova-like eruption in 1919. Our analysis shows that the extinction towards the central knot is much higher than previously thought, with c(H beta) = 2.0. The outer nebula is less reddened, with c(H beta) = 1.04. We find that the outer nebula has a Ne/O ratio higher than the average PN value. The electron temperature we derive for the central knot varies widely depending on the diagnostic used. The [O(III)] nebular-to-auroral transition ratio gives a temperature of 20 800 K, while the ratio of the [N(II)] nebular and auroral lines gives T(e) = 15 200 K. The helium line ratios lambda 5876/lambda 4471 and lambda 6678/lambda 4471 imply temperatures of 350 and 550 K, respectively. Weakly temperature-sensitive O(II) recombination line ratios imply similarly low electron temperatures. Abundances derived from recombination lines are vastly higher than those found from collisionally excited lines, with the abundance discrepancy factor (ADF) for O(2+) reaching 89 - the second highest known value after that found for the hydrogen-deficient knots in Abell 30. The observed temperature diagnostics and abundances support the idea that, like Abell 30, the knot of Abell 58 contains some very cold ionized material. Although the central star is carbon-rich (C/O > 1), the knot is found to be oxygen-rich, a situation not predicted by the single-star 'born-again' theory of its formation. We compare the known properties of Abell 58 to those of Abell 30, Sakurai's Object and several novae and nova remnants. We argue that the abundances in the ejecta observed in A 30 and A 58 have more in common with neon novae than with Sakurai's Object, which is believed to have undergone a final helium flash. In particular, the C/O ratio of less than unity and the presence of substantial quantities of neon in the ejecta of both Abell 30 and Abell 58 are not predicted by very late thermal pulse models.Astronomy & AstrophysicsSCI(E)0ARTICLE41639-164838
Deep spectroscopic luminosity function of Abell 85 : no evidence for a steep upturn of the faint-end slope
No full textIA, AD and ALS acknowledge partial support from the INFN grant InDark and from the grant Progetti di Ateneo TO Call 2012 0011 ‘Marco Polo’ of the University of Torino.We present a new deep determination of the spectroscopic luminosity function (LF) within the virial radius of the nearby and massive Abell 85 (A85) cluster down to the dwarf regime (M* + 6) using Very Large Telescope/Visible Multi-Object Spectrograph (VLT/VIMOS) spectra for ∼2000 galaxies with mr ≤ 21 mag and 〈μe,r〉 ≤ 24 mag arcsec−2. The resulting LF from 438 cluster members is best modelled by a double Schechter function due to the presence of a statistically significant upturn at the faint end. The amplitude of this upturn (αf ~ -1.58+0.19-0.15), however, is much smaller than that of the Sloan Digital Sky Survey (SDSS) composite photometric cluster LF by Popesso et al., αf ∼ −2. The faint-end slope of the LF in A85 is consistent, within the uncertainties, with that of the field. The red galaxy population dominates the LF at low luminosities, and is the main factor responsible for the upturn. The fact that the slopes of the spectroscopic LFs in the field and in a cluster as massive as A85 are similar suggests that the cluster environment does not play a major role in determining the abundance of low-mass galaxies.Peer reviewe
Lewis & Clark: Voyage of Discovery
No full textNonfiction by Stephen E. Ambrose, photographs by Sam Abell National Geographic Society (Hardcover, $35.00, ISBN: 0792270843, 10/1998) Don\u27t expect Ambrose\u27s second treatment of the Lewis and Clark expedition to retread his Undaunted Courage (1996), a huge-selling biography of Meriwether Lewis. An inspection of both books reveals only tiny verbatim repetition, and the cause soon becomes clear: whereas the biography held to the form\u27s stricture that the author be detached from his subject, this photo album proclaims Ambrose\u27s 20-year-long personal obsession (as he puts it) with the epic story. Since 1976 he and his family have spent their summers along the route taken by the Corps of Discovery; some family members have even moved to Montana because of their devotional interest in Lewis and Clark. Ambrose, drawing on his hikes and canoe trips to all the monuments between St. Louis and Fort Clatsop associated with the explorers, melds his memories and own journal entries with a new Lewis and Clark narrative spiced by entries from their journals. Akin to religious pilgrims, Ambrose and companions (including Dayton Duncan and film producer Ken Burns) often re-read passages from those journals at the locale an entry was written, allowing Ambrose to comment on the place\u27s contemporary appearance, whether pristine (Gates of the Rocky Mountains), or altered (the dammed-up Missouri River). The visual difference between Duncan and Burns\u27 Lewis & Clark (1997) and this Ambrose treatment is notable: the former uses nineteenth-century paintings; the latter contemporary National Geo-style photographs of the vistas. Ambrose remarks that his obsession changed his life, and surely his travelogue/tribute will change the vacation plans of some readers as well. Popular, beyond doubt. ―Gilbert Taylor Copyright © 1998, American Library Association. All rights reserved.https://egrove.olemiss.edu/mwp_books/1178/thumbnail.jp
Comparison of new memory surface hardening models for prediction of high cyclic loading (Comparaison de nouveaux modèles de surface de mémoire à durcissement pour la prévision de fortes charges cycliques)
No full textThis paper presents an objective comparison between two recent constitutive models employing the concept of the hardening memory surface to predict the high cyclic loading behaviour of granular soils. The hardening memory surface is applied to the well-known Severn-Trent sand and the SANINSAND04 constitutive models. While the addition of the new model surface (the memory surface) leads to enhanced model capabilities, slight differences in the implementation can lead to different model performances and simulations. This paper describes the differences between the two implementations and highlights the most relevant modelling ingredi-ents to predict particular features of the cyclic soil behaviour. This paper will help the reader in selecting the most suitable model and related ingredients for a particular geotechnical application.Accepted Author ManuscriptGeo-engineerin
Some aspects of narrative method
No full textThe idea of abstracting and/or generalising the structure of a narrative (i.e. a set of weakly connected human actions) using a mapping rule which creates either a tolerance (a symmetric reflexive relationship) or an equivalence on the domain set is explored. The paper is an extension of earlier work by the author. A detailed example of the use of narrative analysis is provided which links the analysis into a game-theoretic context
