Orality-Literacy Theory and the Victorian Sermon
In this study, I expand the scope of the scholarship that Walter Ong and others have done in orality-literacy relations to examine the often uneasy juxtaposition of the oral and written traditions in the literature of the Victorian pulpit. I begin by examining the intersections of the oral and written traditions found in both the theory and the practice of Victorian preaching. I discuss the prominent place of the sermon within both the print and oral cultures of Victorian Britain; argue that the sermon's status as both oration and essay places it in the genre of "oral literature"; and analyze the debate over the extent to which writing should be employed in the preparation and delivery of sermons.

A Communication Based Model of Power
We are affected greatly by power, and often do not understand what power is, how it is used, and its many other facets. Power and communication are interrelated, but how they relate to each other has been hard to understand. The model presented in this thesis explicates the relationship between the two critical variables. Power is portrayed as a hierarchical structure that is based on influence (communication) where the intensity and likelihood of success of power attempts increase as the level of power increases. The hierarchical structure has four levels, including influence at its base, and prominence, authority and control at the higher levels.

Compact location problems with budget and communication constraints
The authors consider the problem of placing a specified number p of facilities on the nodes of a given network with two nonnegative edge-weight functions so as to minimize the diameter of the placement with respect to the first weight function subject to a diameter or sum-constraint with respect to the second weight function. Define an ({alpha}, {beta})-approximation algorithm as a polynomial-time algorithm that produces a solution within {alpha} times the optimal value with respect to the first weight function, violating the constraint with respect to the second weight function by a factor of at most {beta}. They show that in general obtaining an ({alpha}, {beta})-approximation for any fixed {alpha}, {beta} {ge} 1 is NP-hard for any of these problems. They also present efficient approximation algorithms for several of the problems studied, when both edge-weight functions obey the triangle inequality.

Compact location problems with budget and communication constraints
We consider the problem of placing a specified number p of facilities on the nodes of a given network with two nonnegative edge-weight functions so as to minimize the diameter of the placement with respect to the first distance function under diameter or sum-constraints with respect to the second weight function. Define an ({alpha}, {beta})-approximation algorithm as a polynomial-time algorithm that produces a solution within a times the optimal function value, violating the constraint with respect to the second distance function by a factor of at most {beta}. We observe that in general obtaining an ({alpha}, {beta})-approximation for any fixed {alpha}, {beta} {ge} 1 is NP-hard for any of these problems. We present efficient approximation algorithms for the case, when both edge-weight functions obey the triangle inequality. For the problem of minimizing the diameter under a diameter Constraint with respect to the second weight-function, we provide a (2,2)-approximation algorithm. We. also show that no polynomial time algorithm can provide an ({alpha},2 {minus} {var_epsilon})- or (2 {minus} {var_epsilon},{beta})-approximation for any fixed {var_epsilon} > 0 and {alpha},{beta} {ge} 1, unless P = NP. This result is proved to remain true, even if one fixes {var_epsilon}{prime} > 0 and allows the algorithm to …

Leadership Communication Among Kindergarten Children in a Structured Play Environment
This study examines the enactment of leadership communication during videotaped play sessions of thirty kindergarten children. Eighteen of the children demonstrated skills in a cluster of five specific leadership behaviors. All five coders agreed that these eighteen children were sometimes leaders of their individual triad. The coders further agreed that the leadership in the triads flowed from one child to another as the session progressed. The study concluded that leadership is a facilitative process that is fluid rather than statically centered in one or more participants.

DSI3D-RCS: Theory manual
The DSI3D-RCS code is designed to numerically evaluate radar cross sections on complex objects by solving Maxwell`s curl equations in the time-domain and in three space dimensions. The code has been designed to run on the new parallel processing computers as well as on conventional serial computers. The DSI3D-RCS code is unique for the following reasons: Allows the use of unstructured non-orthogonal grids, allows a variety of cell or element types, reduces to be the Finite Difference Time Domain (FDTD) method when orthogonal grids are used, preserves charge or divergence locally (and globally), is conditionally stable, is non-dissipative, is accurate for non-orthogonal grids. This method is derived using a Discrete Surface Integration (DSI) technique. As formulated, the DSI technique can be used with essentially arbitrary unstructured grids composed of convex polyhedral cells. This implementation of the DSI algorithm allows the use of unstructured grids that are composed of combinations of non-orthogonal hexahedrons, tetrahedrons, triangular prisms and pyramids. This algorithm reduces to the conventional FDTD method when applied on a structured orthogonal hexahedral grid.

Status of magnetically-insulated power transmission theory
The theory of magnetically-insulated power flow has improved dramatically over the last two decades since the early works of Creedon, Lovelace and Ott, Ron, Mondelli, and Rostoker, and of Bergeron. During the intervening years theoretical improvements included a complete general kinetic theory that involved distributions of electrons based on quasi-conserved canonical variables and was used to study flow stability and to analyze simulations and pulsers with voltage adders. The status of theory at this time allowed them to understand many features of these flows, but did not allow detailed analysis for design and data interpretation. Recent theoretical advances have drastically changed this situation. Two recent static models based on layered flows have allowed them to understand and to improve power coupling in voltage adders, current adders, plasma opening switches and in systems where the vacuum impedance varies along the flow. A dynamic model based upon electrons flowing in one or more thin layers has permitted detailed self-consistent time-dependent calculations which include electron flow. This model accurately predicts experimental and simulational data.

Recent developments in ecological theory: hierarchy and scale
Over the past decade, hierarchy and scale have been adopted as an ecological paradigm. Beyond this new awareness, however, a number of studies have attempted to test the underlying hierarchy theory and developed new analytical applications. The purpose of the present paper is to review these recent developments. Tests of the theory have focused on the prediction that ecological systems should not be uniformly distributed across scale, but grouped or lumped into discrete levels. The predicted breaks in spatial distribution have been found in vegetation transects. Vertebrate weight distributions are also distinctly aggregated, corresponding to the spatial scale at which each species operates. An important development of hierarchy theory has considered extrapolating information upscale. Simply stated, the dynamics of the higher level cannot be represented by the same functional form as its components. One cannot insert the mean parameter value for the components and predict higher level effects. Analytical methods, derived from hierarchy theory, have been developed deal with the problem.

DSM shareholder incentives: Current designs and economic theory
This report reviews recent DSM shareholder incentive designs and performance at 10 US utilities identifies opportunities for regulators to improve the design of DSM shareholder incentive mechanisms to increase the procurement of cost-effective DSM resources. We develop six recommendations: (1) apply shared-savings incentives to DSM resource programs; (2) use markup incentives for individual programs only when net benefits are difficult to measure, but are known to be positive; (3) set expected incentive payments based on covering a utility`s {open_quotes}hidden costs,{close_quotes} which include some transitional management and risk-adjusted opportunity costs; (4) use higher marginal incentives rates than are currently found in practice, but limit total incentive payments by adding a fixed charge; (5) mitigate risks to regulators and utilities by lowering marginal incentive rates at high and low performance levels; and (6) use an aggregate incentive mechanism for all DSM resource programs, with limited exceptions (e.g., information programs where markups are more appropriate).

Theory of self-organized critical transport in tokamak plasmas
A theoretical and computational study of the ion temperature gradient and {eta}{sub i} instabilities in tokamak plasmas has been carried out. In toroidal geometry the modes have a radially extended structure and their eigenfrequencies are constant over many rational surfaces that are coupled through toroidicity. These nonlocal properties of the ITG modes impose strong constraint on the drift mode fluctuations and the amciated transport, showing a self-organized characteristic. As any significant deviation away from marginal stability causes rapid temperature relaxation and intermittent bursts, the modes hover near marginality and exhibit strong kinetic characteristics. As a result, the temperature relaxation is self-semilar and nonlocal, leading to a radially increasing heat diffusivity. The nonlocal transport leads to the Bohm-like diffusion scaling. The heat input regulates the deviation of the temperature gradient away from marginality. The obtained transport scalings and properties are globally consistent with experimental observations of L-mode charges.

Development and Testing of a Resource-Based Theory of International Entry Mode Choice
A firm can deploy a variety of arrangements (entry modes) like wholly owned subsidiaries, joint ventures, contracts, and export modes to implement its product market strategies in foreign countries. Each of these arrangements entails decisions about the location of production facilities and/or marketing operations, and the type of ownership of these operations. The choice of an entry mode is of strategic importance to a firm because it can involve investment of substantial amount of resources and has a strong bearing on the firm's marketing mix. Due to its strategic importance, the entry mode choice phenomenon has been extensively researched. In the past, seven major theories have been proposed but none is able to explain the choice from the complete set of entry modes. Thus, there exists a gap between the theory and practice of entry mode choice. This study provides breakthrough on two fronts. First, it develops a new theory of entry mode choice grounded in the resource-based perspective of the firm. The theory posits that the decision to locate its production and/or marketing operations in a country is related to the actualizability of the firm's competitive advantage in that country. However, the ownership decision is related to the sustainability …

Repository Integration Program: RIP performance assessment and strategy evaluation model theory manual and user`s guide
This report describes the theory and capabilities of RIP (Repository Integration Program). RIP is a powerful and flexible computational tool for carrying out probabilistic integrated total system performance assessments for geologic repositories. The primary purpose of RIP is to provide a management tool for guiding system design and site characterization. In addition, the performance assessment model (and the process of eliciting model input) can act as a mechanism for integrating the large amount of available information into a meaningful whole (in a sense, allowing one to keep the ``big picture`` and the ultimate aims of the project clearly in focus). Such an integration is useful both for project managers and project scientists. RIP is based on a `` top down`` approach to performance assessment that concentrates on the integration of the entire system, and utilizes relatively high-level descriptive models and parameters. The key point in the application of such a ``top down`` approach is that the simplified models and associated high-level parameters must incorporate an accurate representation of their uncertainty. RIP is designed in a very flexible manner such that details can be readily added to various components of the model without modifying the computer code. Uncertainty is also handled …

Coupled elastic-plastic thermomechanically assisted diffusion: Theory development, numerical implementation, and application
A fully coupled thermomechanical diffusion theory describing the thermal and mechanically assisted mass transport of dilute mobile constituents in an elastic solid is extended to include the effects of elastic-plastic deformation. Using the principles of modern continuum mechanics and classical plasticity theory, balance laws and constitutive equations are derived for a continuum composed of an immobile, but deformable, parent material and a dilute mobile constituent. The resulting equations are cast into a finite element formulation for incorporation into a finite element code. This code serves as a tool for modeling thermomechanically assisted phenomena in elastic-plastic solids. A number of simplified problems for which analytical solutions can be derived are used to benchmark the theory and finite element code. Potential uses of the numerical implementation of the theory are demonstrated using two problems. Specifically, tritium diffusion in a titanium alloy and hydrogen diffusion in a multiphase stainless steel are examined.

A new type of massive spin-one boson: And its relation with Maxwell equations
First, the author showed that in the (1, 0) {circle_plus} (0, 1) representation space there exist not one but two theories for charged particles. In the Weinberg construct, the boson and its antiboson carry same relative intrinsic parity, whereas in the author`s construct the relative intrinsic parities of the boson and its antiboson are opposite. These results originate from the commutativity of the operations of Charge conjugation and Parity in Weinberg`s theory, and from the anti-commutativity of the operations of Charge conjugation and Parity in the author`s theory. The author thus claims that he has constructed a first non-trivial quantum theory of fields for the Wigner-type particles. Second, the massless limit of both theories seems formally identical and suggests a fundamental modification of Maxwell equations. At its simplest level, the modification to Maxwell equations enters via additional boundary condition(s).
