The aesthetics of history in the modern English long poem: David Jones’s the anathemata. Basil bunting's briggflatts, Geoffrey Hill's Mercian hymns and Roy fisher's a furnace
No full textDavid Jones, Basil Bunting, Geoffrey Hill and Roy Fisher are major poets in the modernist tradition who have written long poems which incorporate and interrogate history. The Anathemata. Briggflatts. Mercian Hvmns and A Furnace all explore the poet's sense of identity and his relationship to the present by attempting to give order to the past. This thesis examines how this attempt, and the various ideologies, philosophies and aesthetics that have accompanied it, are given form in these poems. It relates detailed readings of the poems to their intellectual and historical contexts. The Introduction outlines the typical features of die modernist long poem and suggests that they are peculiarly suited to expressions of both history and nationalism. Chapter I is a critical assessment of the aesthetics of Wilhelm Worringer and Herbert Read. Chapter II shows how David Jones endeavours to give form to the various histories of The Anathemata by using these aesthetics in conjunction with the historical philosophy of Oswald Spengler, the analysis of myth and ritual of J.G. Frazer and Jessie Weston, and his own nationalism and Roman Catholicism. This chapter accounts for the poem's obscurity by investigating its conflicting ideas of form, and locating it in die context of the Second World War. Chapter III, on Briggflatts. argues that Basil Bunting combines the ideas of Worringer and Read with an autobiographical narrative and a structure derived from music, in order to give die poem a form mirroring both his melancholia and the harmony he perceived in nature. It contends that the histories in the poem are best read as relating to autobiography and not Northumbrian nationalism. Chapter IV shows how Geoffrey Hill refashions the English long poem in a manner close to that of the lyric sequence. It explores notions of empathy and historical continuity in Mercian Hymns. and analyses Hill's ambiguous evocation of his Anglo-Saxon roots in the context of contemporary political discourse. Chapter V discusses the ways in which Roy Fisher enacts different apprehensions of time and history in the dialectical structure of A Furnace, and relates them to the thought of John Cowper Powys. The Conclusion draws together the recurrent themes of the thesis: change and continuity, history and identity, time and timelessness
Evolution of cooperation among tumor cells
No full textThe evolution of cooperation has a well established theoretical framework based on game theory. This approach has made valuable contributions to a wide variety of disciplines, including political science, economics, and evolutionary biology. Existing cancer theory suggests that individual clones of cancer cells evolve independently from one another, acquiring all of the genetic traits or hallmarks necessary to form a malignant tumor. It is also now recognized that tumors are heterotypic, with cancer cells interacting with normal stromal cells within the issue microenvironment, including endothelial, stromal, and nerve cells. This tumor cell???stromal cell interaction in itself is a form of commensalism, because it has been demonstrated that these nonmalignant cells support and even enable tumor growth. Here, we add to this theory by regarding tumor cells as game players whose interactions help to determine their Darwinian fitness. We marshal evidence that tumor cells overcome certain host defenses by means of diffusible products. Our original contribution is to raise the possibility that two nearby cells can protect each other from a set of host defenses that neither could survive alone. Cooperation can evolve as byproduct mutualism among genetically diverse tumor cells. Our hypothesis supplements, but does not supplant, the traditional view of carcinogenesis in which one clonal population of cells develops all of the necessary genetic traits independently to form a tumor. Cooperation through the sharing of diffusible products raises new questions about tumorigenesis and has implications for understanding observed phenomena, designing new experiments, and developing new therapeutic approaches.Author manuscript.

An analysis of the ex post Fisher hypothesis at short and long term
No full textThis paper tests the Fisher effect. The analysis is applied to the U.S.A. It contributes to the existing empirical literature in three ways. First, it considers a panel of short term and long term real interest rates between 1960 and 2008. Second, it explores both the presence of unit root and structural changes in real interest rates, by allowing for interaction between these two assumptions as suggested by the recent work of Lee and Strazicich. The third contribution consists in testing formally for the number of breaks using Bai and Perron (1998, 2003) test.Unit Root, Structural Break, Fisher Hypothesis, Cointegration
The Influence of Irving Fisher on Milton Friedman’s Monetary Economics
No full textThis paper examines the influence of Irving Fisher’s writings on Milton Friedman’s work in monetary economics. We focus first on Fisher’s influences in monetary theory (the quantity theory of money, the Fisher effect, Gibson’s Paradox, the monetary theory of business cycles, and the Phillips Curve, and empirics, e.g. distributed lags.). Then we discuss Fisher and Friedman's views on monetary policy and various schemes for monetary reform (the k% rule, freezing the monetary base, the compensated dollar, a mandate for price stability, 100% reserve money, and stamped money.) Assessing the influence of an earlier economist's writings on that of later scholars is a challenge. As a science progresses the views of its earlier pioneers are absorbed in the weltanschauung. Fisher's Purchasing Power of Money as well as the work of Pigou and Marshall were the basic building blocks for later students of monetary economics. Thus, the Chicago School of the 1930s absorbed Fisher's approach, and Friedman learned from them. However, in some salient aspects of Friedman's work we can clearly detect a major direct influence of Fisher's writings on Friedman's. Thus, for example with the buildup of inflation in the 1960s Friedman adopted the Fisher effect and Fisher's empirical approach to inflationary expectations into his analysis. Thus, Fisher's influence on Friedman was both indirect through the Chicago School and direct. Regardless of the weight attached to the two influences, Fisher' impact on Friedman was profound.
Is the Fisher Effect for Real? A Reexamination of the Relationship Between Inflation and Interest Rates
No full textThe basic puzzle about the so-called Fisher effect, in which movements in short-term interest rates primarily reflect fluctuations in expected inflation, is why a strong Fisher effect occurs only for certain periods but not for others. This paper resolves this puzzle by reexamining the relationship between inflation and interest rates with modern time-series techniques. Recognition that the level of inflation and interest rates may contain stochastic trends suggests that the apparent ability of short-term interest rates to forecast inflation in the postwar United States is spurious. Additional evidence does not support the presence of a short-run Fisher effect but does support the existence of a long-run Fisher effect in which inflation and interest rates trend together in the long run when they exhibit trends. The evidence here can explain why the Fisher effect appears to be strong only for particular sample periods, but not for others. The conclusion that there is a long-run Fisher effect implies that when inflation and interest rates exhibit trends, these two series will trend together and thus there will be a strong correlation between inflation and interest rates. On the other hand, the nonexistence of a short-run Fisher effect implies that when either inflation and interest rates do not display trends, there is no long-run Fisher effect to produce a strong correlation between interest rates and inflation. The analysis in this paper resolves an important puzzle about when the Fisher effect appears in the data.
