To love what is near : self, language, and world in the poetry of William Stafford

Tammaro, Thomas M. January 1980 (has links)
The present study shows that the process of composition is of foremost consideration and importance in William Stafford's poetics, and that his idea of the creative process can be understood as being composed of an organic relationship between self, language, and world, and of the writer's continual encounter with those elements during the creative act. The method for presenting a study of William Stafford's poetics in this dissertation comes from an examination of his poetry, essays, and interviews. The results of this examination provide the background for a detailed analysis of each element of the organic relationship--self, language, and world--as it appears in selected poems. Reading Stafford's poetry as a series of encounters with self, language, and world offers a view of Stafford as a writer deeply engaged in the creative process and provides a way of reading his poetry with greater comprehension and appreciation of his poetic vision.Chapter One, "Poetry As Process," provides an overview of the debate which began in the mid-1950s between the proponents of New Criticism and the shapers of the "new poetry." Though Stafford was not a spokesman for the new poetry, his poetry and essays about the nature of the creative process share many of the characteristics which have come to be associated with the new poetry, especially the revived discussions of "open" and "organic" form. An analysis of his writings shows that Stafford believes the process of writing to be more important than the end product, the poem, since it is the process of composition which defines the self. For Stafford, creativity is an organic process, consisting of the writer's persistent encounter with self and world as expressed in language.Chapter Two, "Encounter With Self," shows teat, for Stafford, writing is a manifestation of self, and that the self is dynamic rather than static, constantly being shaped by experience. The chapter shows that Stafford views the writing process as a highly subjective experience whereby he attempts to articulate his most deeply felt intuitions and feelings. An analysis of selected poems reveals that Stafford views poetry as a liberating force, a way of discovering the authentic self, with the poem becoming an extension of self.In Chapter Three, "Encounter With Language," Stafford's view of language is examined, revealing his belief that a trusting acceptance of the language of every day speech leads to the discovery of a coherence that exists in language. Since writing, for Stafford, is an attempt to uncover those mysteries which exist in daily language, he is suspicious of any prescribed rule or form that impedes the natural flow of language. He affirms intuition and imagination, rather than reason, as guides.Chapter Four, "Encounter With the World," examines the third element of the organic relationship, the world. An analysis of his poetry shows Stafford constantly working toward those moments of spiritual and mystical awakening. Because of his close attention to his immediate experience, Stafford's poems become small stories, interpreting the world for all who share in language and experience. For Stafford, imagination allows the self, through language, to construct a view of the world.

Tuesta, Napoleon Caro 07 April 2011 (has links)
Em [12] J.T.

Uma pergunta natural é se todo ideal à esquerda ou à direita de\' D IND. n\'(K) pode ser gerado por dois elementos. Neste trabalho provaremos que todo ideal à esquerda ou à direita do anel \'E IND. n\'(K) := K((\'x IND. 1\' ... \'x IND. n\'))(\' partial IND. 1, ...\'partial IND. n\') de operadores diferenciais sobre o corpo das séries de Laurent K((\'x IND. 1\', ...\'x IND. n\')) é gerado por dois elementos.

The low-pressure partial-melting behaviour of natural boron-bearing metapelites from the Mt Stafford area, Central Australia

Spicer, Esme Marelien 12 1900 (has links)
Thesis (DSc)--University of Stellenbosch, 2011. / ENGLISH ABSTRACT: This study has examined the 3 kbar partial melting behaviour of 4 metapelites collected from the highest grade rocks occurring below the anatectic zone of the Mt Stafford area, Arunta Inlier, central Australia. In this area, metasediments are interpreted to have undergone partial melting within the andalusite stability field, possibly as a result of a lowering of the metapelite solidus by the presence of boron in the rocks. Two of the samples were two mica metapelites (MTS70 and MTS71) that both contained significant quantities of tourmaline and were thus boron enriched. The other two samples were biotite metapelites. One of these rocks contains only a trace of tourmaline (MTS8) and the other is tourmaline free (MTS7). Despite expectations that muscovite in the two mica samples would break down via a subsolidus reaction, muscovite was stable to above 750 C due to the incorporation of Ti, phengitic and possibly F components into its structure. Between 750 and 800 C, muscovite melted out completely via a coupled muscovite + biotite fluid-absent incongruent reaction. In the most mica-rich sample this reaction produced ~ 60 % melt at 800 C. In the biotite metapelites, biotite melting began at a temperature below 800 C and was accompanied by very modest melt production at this low temperature. In contrast to the two mica metapelites, the main pulse of melt production in these samples occurred at a temperature between 850 and 950 C. In both these samples biotite + melt coexistence persisted for a temperature range in excess of 150 C, and in MTS8, biotite was still in the run products at 950 C. The very refractory nature of these evolved biotite compositions is most likely a consequence of both the presence of a Ti buffering phase in the assemblage (ilmenite) and the essentially plagioclase-free nature of the starting compositions. Under the fluid-absent conditions of this study tourmaline is clearly a reactant in the partial melting process, but does not appear to shift the fluid-absent incongruent melting reactions markedly. Neither quartz, nor andalusite was completely consumed in the melting reactions, indicating the metastable persistence of andalusite to higher than the wet solidus temperatures. The assemblages do not change much with increasing temperature and mimic the field relationships. The fluid-absent melting experiments indicated that the main pulse of melting occurred between 850 and 950 °C, significantly higher than indicated by the field evidence of 600 to 675 °C, therefor disequilibrium in the experiments can not be ruled out. The presence of a fluid during partial melting at Mt Stafford provides therefor an explanation of the low temperatures at which melting occurred. / AFRIKAANSE OPSOMMING: Die 3 Mpa vloeistof-vrye gedeeltelike smelting van 4 metapeliete, gekollekteer van die hoogste graad rotse net onder die anatektiese sone van die Mt Stafford area, Arunta inlêer, sentraal Australië, is bestudeer. Die metapeliete van hierdie area word geinterpreteer dat hulle gedeeltelike smelting in die andalusiet stabiliteitsveld ondergaan het, moontlik as 'n resultaat van die verlaging van die metapeliet solidus as gevolg van die teenwoordigheid van boor. Twee van die monsters bestudeer was twee-mika metapeliete (MTS70 en MTS71) met beduidende hoeveelhede toermalyn en is dus boor-verryk. Die ander twee monsters was biotiet metapeliete, waarvan een spoorhoeveelhede toermalyn (MTS8) bevat het en die ander toermalyn vry was (MTS7). Ten spyte van verwagtinge dat muskoviet in die twee mika monsters sou afbreek via 'n subsolidus reaksie, was dit stabiel tot bo 750°C as gevolg van die vervanging van Ti, fengitiese en moontlik F komponente in die muskoviet struktuur. Tussen 750 en 800°C het muskoviet heeltemal gesmelt deur die vloeistof-vrye gekoppelde muskoviet+biotiet reaksie. In die monster met die meeste mika het hierdie reaksie ~ 60 % gesmelt by 80°C en lae hoeveelhede smelt is by hierdie lae temperature geproduseer. In kontras met die twee-mika metapeliete het die hoof puls van smeltproduksie in hierdie monsters plaasgevind tussen 850 en 950°C. In beide hierdie monsters het biotiet+smelt 150°C. Biotiet was steeds ongesmelt in MTS8 by 950°. Die hoë refraktoriese natuur van hierdie biotiet samestellings is hoogs waarskynlik 'n gevolg van die teenwoordigheid van 'n Ti-bufferende fase (ilmenite) en die afwesigheid van plagioklaas in die begin samestellings. Toermalyn is duidelik 'n reaktant in hierdie vloeistof-vrye gedeeltelike smelting studie, maar dra nie beduidend by tot die verlaging van die inkongruente smeltingsreaksies nie. Nie kwarts of andalusiet het heeltemal gesmelt oor die temperatuurreeks nie, wat aandui dat die andalusiet stabiel is by temperature hoër as die nat solidus. Die mineraalverspreidings verander nie veel met verhoging in temperatuur nie en mimiek dus die veld verwantskappe. Die vloeistof-vrye smeltings eksperimente het aangedui dat die hoofpuls van smelting tussen 850 en 950°C geskied het, wat aansienlik hoër is soos aangedui uit die veldgetuienis van 600 tot 675°C, dus is die moontlikheid van disekwilibrium gedurende die eksperimente 'n moontlikheid. Die moontlikheid dat vloeistof teenwoordig was tydens die smeltproses by Mt Stafford verskaf dus 'n oplossing vir die lae temperature wat tydens smelting bereik is.
