    Gladstone and the Bank of England: a Study in Mid-Victorian Finance, 1833-1866

    GLADSTONE AND THE BANK OF ENGLAND: A STUDY IN MID-VICTORIAN FINANCE, 1833-1866 Patricia Caernarv en-Smith, B.A. Thesis Prepared for the Degree of MASTER OF ARTS UNIVERSITY OF NORTH TEXAS May 2007 APPROVED: Denis Paz, Major Professor Adrian Lewis, Committee Member and Chair of the Department of History Laura Stern, Committee Member Sandra L. Terrell, Dean of the Robert B. Toulouse School of Graduate Studies Caernarven-Smith, Patricia. Gladstone and the Bank of England: A Study in Mid- Victorian Finance, 1833-1866. Master of Arts (History), May 2007, 378 pp., 11 tables, bibliography, 275 titles. The topic of this thesis is the confrontations between William Gladstone and the Bank of England. These confrontations have remained a mystery to authors who noted them, but have generally been ignored by others. This thesis demonstrates that Gladstone’s measures taken against the Bank were reasonable, intelligent, and important for the development of nineteenth-century British government finance. To accomplish this task, this thesis refutes the opinions of three twentieth-century authors who have claimed that many of Gladstone’s measures, as well as his reading, were irrational, ridiculous, and impolitic. My primary sources include the Gladstone Diaries, with special attention to a little-used source, Volume 14, the indexes to the Diaries. The day-to-day Diaries and the indexes show how much Gladstone read about financial matters, and suggest that his actions were based to a large extent upon his reading. In addition, I have used Hansard’s Parliamentary Debates and nineteenth-century periodicals and books on banking and finance to understand the political and economic debates of the time.

    Coming Home: The Western, Media, and Masculinity By Norman M. Gendelman A dissertation submitted in partial satisfaction of the requirements for the degree of Doctor of Philosophy in Film & Media in the Graduate Division of the University of California, Berkeley Committee in charge: Professor Kristen Whissel, Chair Professor Mary Ann Doane Associate Professor Abigail De Kosnik Professor Emeritus Scott Simmon Fall 2020 Copyright 2020 by Norman Matthew Gendelman 1 Abstract Coming Home: The Western, Media, and Masculinity by Norman Matthew Gendelman Doctor of Philosophy in Film & Media University of California, Berkeley Professor Kristin Whissel, Chair In its analysis of four postwar Westerns (the films The Last Sunset and Gunman’s Walk, and the television Westerns Have Gun—Will Travel and The Rifleman), this dissertation finds a contradictory ideological strain intrinsic to the genre’s frontier legacy, as well as a critical semiosis specific to its production era. By centralizing the postwar era’s domestic concerns over and against the genre’s typical emphasis on the frontier mythos associated with Theodore Roosevelt, these Westerns subvert the stereotypical frontier/civilization dyad. By reconceiving the genre in a way that privileges “civilization” over “frontier,” this dissertation shows that the crucible of “savage” Nature, which formerly determined the exceptionality of the Westerner’s masculine character (as a synecdoche for an exceptional national one), is a cultural production that turns against civilization itself. Denuded of their naturalizing origin, and depicted as social productions within the dramatic action, the gunmen protagonists of each of these four Westerns additionally appear as complex gender constructions. By juxtaposing allusions from each Western to the ideological and aesthetic history of the genre and the socio-political context of the postwar era, the dissertation approaches the Cold War era as similarly mythological, constructed, and contradictory.

NORTHWESTERN UNIVERSITY Keeping Meaning in Proportion: The Multiplication Table as a Case of Pedagogical Bridging Tools A DISSERTATION SUBMITTED TO THE GRADUATE SCHOOL IN PARTIAL FULFILLMENT OF THE REQUIREMENTS for the degree DOCTOR OF PHILOSOPHY Field of Education and Social Policy – Learning Sciences By Dor Abrahamson EVANSTON, ILLINOIS June, 2004 2 © Copyright by Dor Abrahamson 2004 All Rights Reserved ii 3 ABSTRACT Keeping Meaning in Proportion: The Multiplication Table as a Case of Pedagogical Bridging Tools Dor Abrahamson The broad agenda of this dissertation is the design of mathematics curricula for elementary and middle-school students to build meaning for and fluency with mathematical concepts. The paradigm of the work is design research, which combines empirical and theoretical studies. The empirical substance of this dissertation is a set of studies that were implementations of an experimental curricular unit for 5th-grade students learning the domain of ratio and proportion. The theoretical component of this paper is the apprehending zone (Fuson & Abrahamson, 2004a), a Piagetian–Vygotskiian conceptual–practical model of design, teaching, and learning in mathematics classrooms.
