SELECT LETTERS OF PERCY BYSSHE SHELLEY EDITED WITH AN INTRODUCTION BY RICHARD GARNETT NEW YORK D.APPLETON AND COMPANY X, 3, AND 5 BOND STREET MDCCCLXXXIII INTRODUCTION T he publication of a book in the series of which this little volume forms part, implies a claim on its behalf to a perfe&ion of form, as well as an attradiveness of subjeâ:, entitling it to the rank of a recognised English classic. This pretensión can rarely be advanced in favour of familiar letters, written in haste for the information or entertain ment of private friends. Such letters are frequently among the most delightful of literary compositions, but the stamp of absolute literary perfe&ion is rarely impressed upon them. The exceptions to this rule, in English literature at least, occur principally in the epistolary litera ture of the eighteenth century. Pope and Gray, artificial in their poetry, were not less artificial in genius to Cowper and Gray ; but would their un- their correspondence ; but while in the former premeditated utterances, from a literary point of department of composition they strove to display view, compare with the artifice of their prede their art, in the latter their no less successful cessors? The answer is not doubtful. Byron, endeavour was to conceal it. Together with Scott, and Kcats are excellent letter-writers, but Cowper and Walpole, they achieved the feat of their letters are far from possessing the classical imparting a literary value to ordinary topics by impress which they communicated to their poetry. -

What Literature Knows: Forays Into Literary Knowledge Production
Contributions to English 2 Contributions to English and American Literary Studies 2 and American Literary Studies 2 Antje Kley / Kai Merten (eds.) Antje Kley / Kai Merten (eds.) Kai Merten (eds.) Merten Kai / What Literature Knows This volume sheds light on the nexus between knowledge and literature. Arranged What Literature Knows historically, contributions address both popular and canonical English and Antje Kley US-American writing from the early modern period to the present. They focus on how historically specific texts engage with epistemological questions in relation to Forays into Literary Knowledge Production material and social forms as well as representation. The authors discuss literature as a culturally embedded form of knowledge production in its own right, which deploys narrative and poetic means of exploration to establish an independent and sometimes dissident archive. The worlds that imaginary texts project are shown to open up alternative perspectives to be reckoned with in the academic articulation and public discussion of issues in economics and the sciences, identity formation and wellbeing, legal rationale and political decision-making. What Literature Knows The Editors Antje Kley is professor of American Literary Studies at FAU Erlangen-Nürnberg, Germany. Her research interests focus on aesthetic forms and cultural functions of narrative, both autobiographical and fictional, in changing media environments between the eighteenth century and the present. Kai Merten is professor of British Literature at the University of Erfurt, Germany. His research focuses on contemporary poetry in English, Romantic culture in Britain as well as on questions of mediality in British literature and Postcolonial Studies. He is also the founder of the Erfurt Network on New Materialism. -
Democratic Citizenship in the Heart of Empire Dissertation Presented In
POLITICAL ECONOMY OF AMERICAN EDUCATION: Democratic Citizenship in the Heart of Empire Dissertation Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of the Ohio State University Thomas Michael Falk B.A., M.A. Graduate Program in Education The Ohio State University Summer, 2012 Committee Members: Bryan Warnick (Chair), Phil Smith, Ann Allen Copyright by Thomas Michael Falk 2012 ABSTRACT Chief among the goals of American education is the cultivation of democratic citizens. Contrary to State catechism delivered through our schools, America was not born a democracy; rather it emerged as a republic with a distinct bias against democracy. Nonetheless we inherit a great demotic heritage. Abolition, the labor struggle, women’s suffrage, and Civil Rights, for example, struck mighty blows against the established political and economic power of the State. State political economies, whether capitalist, socialist, or communist, each express characteristics of a slave society. All feature oppression, exploitation, starvation, and destitution as constitutive elements. In order to survive in our capitalist society, the average person must sell the contents of her life in exchange for a wage. Fundamentally, I challenge the equation of State schooling with public and/or democratic education. Our schools have not historically belonged to a democratic public. Rather, they have been created, funded, and managed by an elite class wielding local, state, and federal government as its executive arms. Schools are economic institutions, serving a division of labor in the reproduction of the larger economy. Rather than the school, our workplaces are the chief educational institutions of our lives. -

Gulf Arabs to Create Regional Police Force

The creation of the police force, known as GCC-POL, was announced yesterday at the conclusion of the Gulf bloc’s annual summit in Qatar. Local media have dubbed it the “Gulf Interpol” and say its aim is to improve cooperation against drug trafficking, money laundering and cyber-crime. The GCC is comprised of the energy-rich nations of Saudi Arabia, the UAE, Kuwait, Qatar, Bahrain and Oman. Supporting Sisi’s Egypt Meanwhile, Qatar joined its neighbors at a summit yesterday in supporting Egypt under President Abdel Fattah El-Sisi, whose crackdown on the Doha-backed Muslim Brotherhood had divided the Gulf monarchies for months. In their final statement, leaders of the six- nation Gulf Cooperation Council (GCC) states announced their “full support to Egypt” and the “politi- cal program of President Abdel Fattah El-Sisi”. Convening the Doha summit, which had been short- ened to one day, was made possible only by last-minute Kuwaiti mediation that succeeded in resolving a dispute between Saudi Arabia, the United Arab Emirates and Bahrain with Qatar over the Brotherhood. -

Abstract Impact cratering is an abrupt, spectacular process that occurs on any world with a solid surface. On Earth, these craters are easily eroded or destroyed through endogenic processes. The Moon and Mercury, however, lack a significant atmosphere, meaning craters on these worlds remain intact longer, geologically. In this thesis, remote-sensing techniques were used to investigate impact melt emplacement about Mercury’s fresh, complex craters. For complex lunar craters, impact melt is preferentially ejected from the lowest rim elevation, implying topographic control. On Venus, impact melt is preferentially ejected downrange from the impact site, implying impactor-direction control. Mercury, despite its heavily-cratered surface, trends more like Venus than like the Moon. -
