The Platonic tradition and the theory of rhetoric

Dissertation (Ph.D.)--University of Kansas, Speech Communication and Human Relations, 1981.In spite of the texts of Plato's dialogues and the testimony of ancient and modern scholars, Plato has received relatively little attention as a serious rhetorical theorist. Therefore, this study had three goals: to determine if Plato developed a theory of rhetoric distinct from other classical theories; to describe the elements of Plato's theory; and, to trace the influence of Platonic rhetorical theory on subsequent rhetorical theorists. Plato's dialogues were examined in order to ascertain if Plato developed a theory of rhetoric. While all of the dialogues were consulted, the most important, for the purposes of this study, were the Gorgias, the Phaedrus, the Republic, the Laws, the Statesman, the Menexenus, the Theatetus, the Sophist, the Cratylus, and the Timaeus. The theory which emerged from this investigation was compared with Aristotle's theory of rhetoric as developed in the Rhetoric, the Posterior Analytics, the Nicomachean Ethics, the Politics, the Poetics, and the Topics, to determine if Platonic theory was distinct from Aristotelian rhetorical theory. Subsequently, the rhetorical works of Cicero, Augustine, Fenelon, and Richard Weaver were consulted for evidence of Plato's influence on the development of rhetorical theory. Chapters I-III consider the fundamental tenets of Aristotelian and Platonic rhetorical theory. Seven factors emerged which characterize Plato's theory of rhetoric: (1) Plato defines rhetoric broadly to encompass all forms of persuasive speech; (2) a priori knowledge informs the content of rhetoric; (3) there exists a doctrinaire, in-group orientation in which rhetoric aims to further specific, discoverable, and significant moral ends; (4) there exists a close relationship between rhetorical and poetic causing dramatic imitation, rather than reason, to emerge as the most important method of persuasion; (5) there exists an emphasis on social control, censorship, and doctrinal conformity derived from an anti-egalitarian onlology; (6) dialectic is the only permissable method for rhetorical invention; and, (7) there is a necessary relationship between hermeneutics and epistemology. Plato differs from Aristotle in his assumption that human beings are not rational, in his unwillingness to accord probability any epistemological status, in his broad definition of rhetoric, in his doctrinaire orientation and his emphasis on social control, and in his use of dialectic. For these reasons, it is concluded that Platonic and Aristotelian theory represent divergent traditions in rhetoric. Chapters IV-VII consider Plato's influence on subsequent rhetorical theorists in an effort to show that Plato influenced the development of rhetorical theory. It was found that while Cicero shared some ideas in common with Plato, he did not adopt a Platonic theory of rhetoric. Augustine, Fenelon, and Richard Weaver, however, tend to depend more heavily on Plato raising the possibility that there exists on ongoing Platonic tradition in rhetorical theory

Shadow world evaluation of the Yang-Mills measure

A new state-sum formula for the evaluation of the Yang-Mills measure in the Kauffman bracket skein algebra of a closed surface is derived. The formula extends the Kauffman bracket to diagrams that lie in surfaces other than the plane. It also extends Turaev's shadow world invariant of links in a circle bundle over a surface away from roots of unity. The limiting behavior of the Yang-Mills measure when the complex parameter approaches -1 is studied. The formula is applied to compute integrals of simple closed curves over the character variety of the surface against Goldman's symplectic measure.Comment: Published by Algebraic and Geometric Topology at http://www.maths.warwick.ac.uk/agt/AGTVol4/agt-4-17.abs.htm

EVALUATING IMPLEMENTATION SCHEDULES FOR INVESTMENTS IN STRATEGIC INFORMATION TECHNOLOGIES: FRAMEWORK AND APPLICATION TO EDI

We develop a framework based on "project networks" and net present value analysis in order to help managers evaluate investments in infrastructural and strategic information systems that require significant amounts of time and money to implement. The framework, which we term "value networks", supports decomposition of investment projects into separate increments, offers a means to represent crucial dependencies that affect the creation of IT business value, and provides a basis for developing a measurement methodology which can be used from the planning through the implementation stages. This enables the user to identify the implications of choosing among different implementation schedules. We illustrate these ideas by examining how our framework can used to evaluate investments in Electronic Data Interchange (EDI) and Cash Management Systems (CMS).Information Systems Working Papers Serie

IDENTIFYING BUSINESS VALUE LINKAGES FOR INFORMATION TECHNOLOGY: AN EXPLORATORY APPLICATION TO TREASURY WORKSTATIONS

Pervasive and costly automation of information handling activities continues to put pressure on senior managers to quantify the contributions of information technology IT to the strategic goals of the firm. This paper proposes the use of "business value linkage BVL" correlation tests to provide evidence that investments in IT create the desired higher order, economic impacts. We argue that managers should carry out econometric tests which are specialized to capturing primal, revenue-enhancing impacts, as opposed to dual, cost-reducing impacts. As an illustration, a sample BVL correlation test is constructed to quantify the impact of a "treasury workstation" system on a large commercial bank's ability to increase demand balances from corporate customers. We conclude with some thoughts about where BVL correlation will provide the bt results for managers.Information Systems Working Papers Serie

MODELING AND MEASURING THE BUSINESS VALUE OF INFORMATION TECHNOLOGY

Determining the 'business value' of information technology (IT) requires managers to choose performance measures which are well-suited to capturing the economic impacts of the application they are evaluating. In this paper, the authors discuss a promising approach for bridging the gap between a theory for rational decisions and management practice in evaluating investments in IT: Data Envelopment Analysis (DEA). The referent discipline for the discussion is production economics, and the authors review basic concepts concerning performance measurement, efficiency, productivity and economic contribution or value-added from an economist's perspective. DEA's promise lies in its ability to handle multiple input and output production environments and its management action orientation. As an illustration of this potential, DEA is applied to assessing the performance of an automated teller machine (ATM) network, an IT which creates economic impacts at various organizational levels of a commercial bank.Information Systems Working Papers Serie

Running up the Bid: Modeling Seller Opportunism in Internet Auctions

Although the Internet is great for transferring information, transactions in Internet auctions have a greater information asymmetry than corresponding transactions in traditional environments because current auction market mechanisms allow the seller to remain anonymous and to easily change identities. Buyers must rely on the seller\u27s description of a product and ability to deliver the product as promised. Internet auction environments make opportunistic behavior more attractive to sellers because the chance of detection and punishment is decreased. In this research, we examine auction data to see the effect of opportunism in the online auction environment
