  1. Pioneering women archivists in England: Ethel Stokes (1870–1944), record agent

    Shepherd, E
    This paper explores the life of Miss Ethel Stokes who was significantly involved in several major historical, literary and archival enterprises in early twentieth-century England. She established the Records Preservation Section of the British Records Association, she edited historical records and wrote for publication in works of reference including local and British Record Society volumes, the Victoria County History of England and the Complete Peerage, and she established an independent and successful business as a record agent, Stokes and Cox. The article is the first in a planned series which will study the lives and professional contributions of pioneering women...

  2. Simultaneous Rheoelectric Measurements of Strongly Conductive Complex Fluids

    Helal, Ahmed H.; Divoux, Thibaut Louis Alexandre; McKinley, Gareth H
    We introduce an modular fixture designed for stress-controlled rheometers to perform simultaneous rheological and electrical measurements on strongly conductive complex fluids under shear. By means of a nontoxic liquid metal at room temperature, the electrical connection to the rotating shaft is completed with minimal additional mechanical friction, allowing for simultaneous stress measurements at values as low as 1 Pa. Motivated by applications such as flow batteries, we use the capabilities of this design to perform an extensive set of rheoelectric experiments on gels formulated from attractive carbon-black particles, at concentrations ranging from 4 to 15 wt %. First, experiments on gels at rest...

    Jurkovic, D; Memtsa, M; Sawyer, E; Donaldson, A; Jamil, A; Schramm, K; Sana, Y; Otify, M; Farahani, L; Nunes, N; Ambler, G; Ross, JA
    OBJECTIVE: Methotrexate is routinely used worldwide for medical treatment of clinically stable women with tubal ectopic pregnancies. This is despite the lack of robust evidence to show its superior effectiveness over expectant management. The aim of our multicentre randomised trial study was to compare the success rates of methotrexate with placebo for the conservative treatment of tubal ectopic pregnancies. METHODS: The study was multicentre; it took place in three UK early pregnancy units between January 2006 and June 2014. Inclusion criteria were clinically stable women with a conclusive ultrasound diagnosis of a tubal ectopic pregnancy presenting with low serum β-hCG...

  4. The Bursty Star Formation Histories of Low-mass Galaxies at 0.4 < z < 1 Revealed by Star Formation Rates Measured From Hβ and FUV

    Guo, Yicheng; Rafelski, Marc; Faber, S. M.; Koo, David C.; Krumholz, Mark R.; Trump, Jonathan R.; Willner, S. P.; Amorín, Ricardo; Barro, Guillermo; Bell, Eric F.; Gardner, Jonathan P.; Gawiser, Eric; Hathi, Nimish P.; Koekemoer, Anton M.; Pacifici, Camilla; Pérez-González, Pablo G.; Ravindranath, Swara; Reddy, Naveen; Teplitz, Harry I.; Yesuf, Hassen
    We investigate the burstiness of star formation histories (SFHs) of galaxies at 0.4 < z < 1 by using the ratio of star formation rates (SFRs) measured from Hβ and FUV (1500 Å) (Hβ-to-FUV ratio). Our sample contains 164 galaxies down to stellar mass (M_*) of 10^(8.5) M_⊙ in the CANDELS GOODS-N region, where Team Keck Redshift Survey Keck/DEIMOS spectroscopy and Hubble Space Telescope/WFC3 F275W images from CANDELS and Hubble Deep UV Legacy Survey are available. When the ratio of Hβ- and FUV-derived SFRs is measured, dust extinction correction is negligible (except for very dusty galaxies) with the Calzetti attenuation...

  5. Effect of the star formation histories on the SFR-M_* relation at z ≥ 2

    Cassarà, L. P.; Capak, P.; Scoville, N.
    We investigate the effect of different star formation histories (SFHs) on the relation between stellar mass (M_∗) and star formation rate (SFR) using a sample of galaxies with reliable spectroscopic redshift z_(spec)> 2 drawn from the VIMOS Ultra-Deep Survey (VUDS). We produce an extensive database of dusty model galaxies, calculated starting from a new library of single stellar population (SSPs) models, weighted by a set of 28 different star formation histories based on the Schmidt function, and characterized by different ratios of the gas infall timescale τ_(infall) to the star formation efficiency ν. Dust extinction and re-emission were treated by...

  6. ‘Repeat Abortion’, a phrase to be avoided? Qualitative insights into labelling and stigma

    Newton, V
    Background In recent years there has been growing international interest in identifying risk factors associated with ‘repeat abortion’, and developing public health initiatives that might reduce the rate. This article draws on a research study looking at young women's abortion experience in England and Wales. The study was commissioned with a specific focus on women who had undergone more than one abortion. We examine what may influence women's post-abortion reproductive behaviour, in addition to exploring abortion-related stigma, in the light of participants' own narratives. Study design Mixed-methods research study: a quantitative survey of 430 women aged 16–24 years, and in-depth qualitative...

  7. Reconfiguring the shipping news: Maritime's hidden histories and the politics of gender display


    This paper discusses the book Hello Sailor! The Hidden History of Gay Life at Sea published in 2003 by Paul Baker and Jo Stanley, re-interpreted as a landmark temporary exhibition Hello Sailor! Gay Life on the Ocean Wave at the Merseyside Maritime Museum, Liverpool from where it travelled in 2007 to other maritime museums. Based largely on oral history interviews and part of a hidden histories project, the book recovers the previously repressed twentieth-century histories of gay sailors in the 'gay heaven' of the merchant navy. This paper explores the construction of gay seafarers presented in the book and exhibition....

  8. Insurgent Remains: Afterlives of the American Revolution, 1770-1820

    Stapely, Emma Tiril
    Insurgent Remains disturbs the identification of the American Revolution with U.S. national beginnings by tracing it through its literary aftereffects in the period with which it is identified, 1770-1820. While the American Revolution is thought to have concluded with the Treaty of Paris (1783) and the “birth of the United States, Insurgent Remains reads texts produced in the decades following the peace for delineations of ongoing Revolutionary experiences characterized by loss and constraint that demand creative, collective responses without guarantee. In chapters organized around the re-use and re-circulation of “old” forms and formats—allegory, anthology, tragedy, and petition—I propose that the...

  9. Exploring Sexual History Taking In One Health Center: A Focused Ethnography

    Sowicz, Timothy Joseph
    Sexual history taking is the clinical practice of collecting information about patients’ sexual health. Despite the availability of guidelines for conducting a sexual history, variability in the documentation of sexual histories exists. In addition to documentation, the literature on sexual histories is limited to their content, barriers to collecting them, and interventions to improve their documentation and health care providers’ comfort and confidence in taking them. Additionally, the methods used to explore sexual history taking have been homogeneous. Absent from this literature is an in-depth understanding of the contextual factors affecting the collection of sexual history data as well as...

  10. The Effect of Sequential Exposure to Antigenically Drifted Strains of influenza on Antibody Specificity and Antibody Mediated Protection

    Linderman, Susanne Liane
    Antibodies (Abs) elicited by influenza viruses often bind with higher affinities to past influenza strains than to the current strain. This has been associated with the hypothesis of “original antigenic sin” which postulates that B cell clones elicited by prior exposure are recalled at the expense of generating a strain-specific response to the current strain. It is clear that prior exposures to influenza viruses focus the response on conserved epitopes of influenza’s hemagglutinin (HA) glycoprotein. Here, pre-exposure to influenza is shown to affect Ab fine specificity and Ab mediated protection in mice, ferrets, and humans. Sequential vaccination of mice with...

  11. Ambitious Confusion: Recovering the Unthought in Contemporary Memorials to the Antebellum South

    Kearney, Aundeah Joann
    Ambitious Confusion: Recovering the Unthought in Contemporary Memorials to the Antebellum South Aundeah J. Kearney Thadious M. Davis This dissertation examines how contemporary authors and artists who craft memorials to the antebellum South reconcile the presence of disruptive artifacts with narratives of history they inherit as members of a national collective, actively engaging with shared memories of critical moments in the nation’s past. In this study, I identify ambitious confusion as a generative state which moves beyond mere recognition of conflicting histories toward a memorial that successfully manages the reintegration of previously excised artifacts of history. I borrow the term “unthought” from Rinaldo...

  12. In the Age of Freedom, in the Name of Justice": Slaves, Slaveholders, and the State in the Late Ottoman Empire and Early Turkish Republic, 1857-1933

    Karamursel, Ceyda
    This dissertation concerns itself with the practice of slavery in the Ottoman Empire and the Turkish Republic in the second half of the nineteenth and early decades of the twentieth centuries. It places slavery at the intersection of the new liberal political order that began to form in the mid-1850s, the expulsion of the Caucasian peoples and their subsequent transplantation in the Ottoman Empire, and the international anti-slavery law that was taking shape simultaneously. It examines the social and legal (trans)formations at this particular juncture, traces the legal making and perpetuation of “Circassianness” as an “enslavable” ethnic category, and consequently...

  13. Modulaciones Temporales, Sexualidad y Literatura: Narrativa Argentina Contemporanea

    Gómez, Juan Ariel
    Los rastros temporales en representaciones literarias e indagaciones historiográficas recientes de las sexualidades en Argentina movilizan estos tres capítulos. En ellos una persistencia se manifiesta como la doble modulación temporal en la forma y en el contenido subjetivo o experiencial. Tiempo es forma y contenido, y en cada sección, ellos constituyen reflexiones acerca de la existencia contemporánea que destaco en tres modulaciones. Primero examino en la ficción breve de Naty Menstrual y en las crónicas de Alejandro Modarelli una economía de la continuidad exacerbada y de la discontinuidad que múltiples voces construyen. La expresión de una subjetividad trans se temporaliza...

  14. Mexican Migrants and the Rise of the Deportation Regime, 1942-2014

    Goodman, Adam
    This dissertation traces the rise of the deportation regime in the United States from 1942 to the present. It reveals that the origins of the regime are inextricably intertwined with the history of Mexican migration. It uses a diverse array of English- and Spanish-language archival sources from the United States and Mexico, more than twenty oral histories, and materials obtained through the Freedom of Information Act to show how deportation has changed—qualitatively and quantitatively—over the last seventy-two years. This dissertation sheds light on deportation’s magnitude, both past and present. It interrogates the inaccurate and inconsistent ways that scholars, journalists, and government...

  15. ¿Hacemos Una Peli? Negrablanca y Los Entornos de un Cine Hecho en Comunidad.

    Fernandez De Llanos, Helena
    ¿Hacemos una peli? es un proyecto de cine comunitario que desarrollé en un área rural del sur de España durante nueve meses. Para realizarlo invité a compañeros profesionales del sector audiovisual y a cualquier persona del pueblo que quisiera participar. Su resultado fílmico es NegraBlanca, un largometraje de 90 minutos que experimenta con las formas de contar a partir del ensamblaje de diversas historias inventadas o recordadas por los participantes en el proyecto. Mi disertación investiga las posibilidades de un modelo de producción cinematográfica con base en la participación de las personas no profesionales, elaborada por Cine Sin Autor, un...

  16. Pwofite Tèt Ou”(Avail YOourself): The Minoritarian Politics of Haitian Music in Paris

    Donnelly, Laura
    Paris functions as a diverse site in which Haitians and French Antilleans come together most significantly in relation to musical interaction. Haitian music in Paris, especially konpa, is frequently paired with Antillean music, specifically zouk, whether it be on the radio, as Antillean stations frequently co-opt konpa or in dance clubs for deejayed events. Thus, konpa and zouk share modes of dissemination and consumption, and are frequently grouped together. These mutually shared spaces of musical consumption enable and promote the formation of connections between Antillean and Haitian communities, enabled by a minoritarian politics rooted in shared colonial histories and coupled...

  17. A Portable Feast: The Production and Use of the Thirteenth-Century Portable Bible 1200-1500

    Devine, Alexander Leo
    This dissertation celebrates the portable one-volume Latin Vulgate bibles produced on an unprecedented scale during the 13th century, particularly between 1230 and 1280, emphasizing their particular significance within the contexts of medieval book production and medieval bible use. The profound changes that these bibles implemented to the physical appearance and format of the Bible (as compact and portable copies of the complete biblical text), generated great innovations in the function and use of the Bible, and were directly responsible for the 13th-century portable bible’s extraordinary success and enduring popularity, in its own time and in ours, and thus their privileged...

  18. Genome sequence, population history, and pelage genetics of the endangered African wild dog (Lycaon pictus)

    Campana, MG; Parker, LD; Hawkins, MTR; Young, HS; Helgen, KM; Szykman Gunther, M; Woodroffe, R; Maldonado, JE; Fleischer, RC
    BACKGROUND: The African wild dog (Lycaon pictus) is an endangered sub-Saharan canid threatened by severe habitat fragmentation, human-wildlife conflict, and infectious disease. A highly specialized carnivore, it is distinguished by its social structure, dental morphology, absence of dewclaws, and colorful pelage. RESULTS: We sequenced the genomes of two individuals from populations representing two distinct ecological histories (Laikipia County, Kenya and KwaZulu-Natal Province, South Africa). We reconstructed population demographic histories for the two individuals and scanned the genomes for evidence of selection. CONCLUSIONS: We show that the African wild dog has undergone at least two effective population size reductions in the last one...

  19. Stochastic coupled simulation of strong motion and tsunami for the 2011 Tohoku, Japan earthquake

    Goda, K; Petrone, C; de Risi, R; Rossetto, T
    © 2016 The Author(s)This study conducts coupled simulation of strong motion and tsunami using stochastically generated earthquake source models. It is focused upon the 2011 Tohoku, Japan earthquake. The ground motion time-histories are simulated using the multiple-event stochastic finite-fault method, which takes into account multiple local rupture processes in strong motion generation areas. For tsunami simulation, multiple realizations of wave profiles are generated by evaluating nonlinear shallow water equations with run-up. Key objectives of this research are: (i) to investigate the sensitivity of strong motion and tsunami hazard parameters to asperities and strong motion generation areas, and (ii) to quantify...

  20. Synthetic recording and in situ readout of lineage information in single cells

    Frieda, Kirsten L.; Linton, James M.; Hormoz, Sahand; Choi, Joonhyuk; Chow, Ke-Huan K.; Singer, Zachary S.; Budde, Mark W.; Elowitz, Michael B.; Cai, Long
    Reconstructing the lineage relationships and dynamic event histories of individual cells within their native spatial context is a long-standing challenge in biology. Many biological processes of interest occur in optically opaque or physically inaccessible contexts, necessitating approaches other than direct imaging. Here, we describe a new synthetic system that enables cells to record lineage information and event histories in the genome in a format that can be subsequently read out in single cells in situ. This system, termed Memory by Engineered Mutagenesis with Optical In situ Readout (MEMOIR), is based on a set of barcoded recording elements termed scratchpads. The...
