Citizenship, Duty and Virtue: A Vision of Jefferson's America

Stine, Anthony Philip 01 January 2011 (has links)
In contemporary American political life, concepts such as duty to country and society often play a role in political discourse, but are often forgotten in the lives of average Americans. The life of the average citizen is focused on issues of economic survival, familial matters, and the diversions that occupy persons. Devotion to country is made an at best secondary concern for Americans. The purpose of this work is to examine the concepts of civic virtue that historically have dominated American political thought, using the writings of Thomas Jefferson and his influences as the primary source material for this effort, as well as the writings of modern western political theorists. Through this work, a conflict emerges between the values of western liberal thought and classic republicanism; to this end, a secondary purpose of this work is to reconcile those differences in an American context. Finally, a third purpose of this work is to offer a theoretical plan for re-connecting the average citizen with concepts of civic virtue through a proposal for public service.

The First Lady of Washington City: Margaret Bayard Harrison Smith, Family, and Politics in the Early Republic

Thweatt, William Denton 05 1900 (has links)
Margaret Bayard Harrison Smith was a prominent member of early Washington City society from the time she and her husband, Samuel Harrison Smith, moved to the blossoming capital in 1800 until her death in 1844. As a longtime resident of Washington, Margaret spent most of her adult life navigating the unique socio-political waters of the capital and developing friendships with many of the most prominent politicians of her time. Mrs. Smith's writings provide firsthand accounts of several important political events including Congress' role in the election of 1800, Jefferson's first inauguration, Madison's first inauguration, and the destruction left by the British after the siege of Washington. Her writings also provide a picture of early undeveloped Washington City, where grand public buildings were largely surrounded by wilderness and connected by muddy roads. While this work looks at the social and political environment that Margaret Smith experienced, it also examines many of the personal concerns that frequented Mrs. Smith's writings. Margaret's views on educating her children, interacting with servants, interacting with the enslaved population of Washington, and dealing with feelings of isolation, due to the distance from her family, are frequently addressed in her letters. Focusing on these aspects of Mrs. Smith's writings allows for a greater examination of the societal norms of her day about gender, class, and race. While Margaret's letters and commonplace books have often been used to examine Washington society and the lives of her prominent friends, there is no biography of Mrs. Smith herself. This dissertation provides the first biography of Margaret Bayard Harrison Smith from her birth until the end of the War of 1812.

THEORY AND PRACTICE: VIEWING INDUSTRIAL INNOVATION AS A PROCESS THROUGH AN EXAMINATION OF THE CREATION OF THE AMERICAN SYSTEM OF MANUFACTURING

Lothstein, Alexander January 2017 (has links)
Despite the vast research on industrial innovation in the United States, little shows innovation as a process from the theoretical origins to its practical application. The image that emerges from the overall literature is one showing only the importance of applied innovation. This thesis argues that historians need to reevaluate how manufacturing advancements are studied in the United States. Using the creation of the American System of Manufacturing as a case study, this study focuses on innovation as a connected process from its theoretical origins to its applied state. This study focuses less on the individuals involved and more on the system itself. This accomplishes two points. First is that it shows that the idea is more important than the peoples. Second is that this thesis provides a greater understanding of how the American System of Manufacturing came to fruition. By examining these two points, this thesis demonstrates that historians need to look beyond the traditional application-only focus that has plagued the study of technological history. Instead historians must show industrial innovation as both the creation of the theoretical concept and the systems practical application. / History

First Time Measurements of Polarization Observables for the Charged Cascade Hyperon in Photoproduction

Bono, Jason S 06 June 2014 (has links)
The parity violating weak decay of hyperons offers a valuable means of measuring their polarization, providing insight into the production of strange quarks and the matter they compose. Jefferson Lab’s CLAS collaboration has utilized this property of hyperons, publishing the most precise polarization measurements for the Λ and Σ in both photoproduction and electroproduction to date. In contrast, cascades, which contain two strange quarks, can only be produced through indirect processes and as a result, exhibit low cross sections thus remaining experimentally elusive. At present, there are two aspects in cascade physics where progress has been minimal: characterizing their production mechanism, which lacks theoretical and experimental developments, and observation of the numerous excited cascade resonances that are required to exist by flavor SU(3)F symmetry. However, CLAS data were collected in 2008 with a luminosity of 68 pb−1 using a circularly polarized photon beam with energies up to 5.45 GeV, incident on a liquid hydrogen target. This dataset is, at present, the world’s largest for meson photoproduction in its energy range and provides a unique opportunity to study cascade physics with polarization measurements. The current analysis explores hyperon production through the γp → K+K+Ξ− reaction by providing the first ever determination of spin observables P, Cx and Cz for the cascade. Three of our primary goals are to test the only cascade photoproduction model in existence, examine the underlying processes that give rise to hyperon polarization, and to stimulate future theoretical developments while providing constraints for their parameters. Our research is part of a broader program to understand the production of strange quarks and hadrons with strangeness. The remainder of this document discusses the motivation behind such research, the method of data collection, details of their analysis, and the significance of our results.

The Davis-Johnston Controversy

Gallaway, B. P. 08 1900 (has links)
Looming large in the manifold problems of the Davis government after the clash of arms at Sumter was the creation of an army to defend the South. Involved in this problem was the extremely important task of expanding forces. No dearth of excellent officer material existed for some of the most able West Point graduates in the Union army had resigned and were eager to serve their section. The major problem was the question of relative rank to be assigned in the new chain of command.

Fragmentation des Quarks et Formation des Hadrons dans la Matière Nucléaire

Dupré, Raphaël 09 November 2011 (has links) (PDF)
La formation des hadrons est, dans le cadre de la théorie quantique de couleur (QCD), un processus non-perturbatif ; cette caractéristique entraîne d'importantes difficultés théoriques. C'est pourquoi, les mesures expérimentales de fragmentation dans différents noyaux sont une nécessité afin d'obtenir des progrès tangibles dans la compréhension des mécanismes de formation des hadrons. La thèse commence par les bases théoriques nécessaires à une telle approche, suivies des principaux modèles qui lui sont associés.La thèse se poursuit par l'analyse de données de Jefferson Lab obtenues à l'aide d'un faisceau d'électrons de 5 GeV incident sur différentes cibles (2H, C, Al, Fe, Sn et Pb). Les produits de la réaction sont mesurés avec le spectromètre CLAS. Les principaux résultats de cette expérience sont : (a) l'analyse multi-dimensionnelle des observables mesurées, qui permet une meilleure confrontation avec les modèles théoriques et l'extraction d'informations temporelles sur la fragmentation, et (b) l'observation d'une atténuation hadronique non-linéaire en fonction du rayon du noyau cible. Dans une partie plus théorique, le générateur d'événements PyQM, développé dans le but de reproduire les données de la collaboration HERMES, est présenté. Les résultats sont mitigés, en effet la base théorique utilisée ne semble pas s'appliquer au cas étudié, néanmoins certaines caractéristiques des données sont reproduites permettant de comprendre leurs origines parfois inattendues. Enfin, les possibilités d'expériences futures, à Jefferson Lab et dans un collisionneur ion-électron (EIC), sont explorées.
