Interactive Frameworks for Investigation of Goal Programming Models: Theory and Practice

This paper discusses means of introducing decision maker input into the goal programming model in order to produce more satisfactory solutions. Both formal interactive methods and informal trial-and-error approaches are discussed. The design criteria for the choice of the initial test solution and the stopping criteria for the final solution are detailed. The area of presentation of results to, and elicitation of preferences from, the decision maker is dealt with. Practical suggestions for means of parameter alteration to produce alternative solutions are given. Finally, the integration of the above issues into an integrated framework is discussed. © 1997 John Wiley & Sons, Ltd.     

REVEALING THE INVISIBLE: GREGORY OF NYSSA ON THE GIFT OF REVELATION

In this essay, Gregory of Nyssa is used as a foil against both John Milbank and Jean‐Luc Marion in order to take a fresh approach to the debate on the “gift” and the theological ramifications for the structure of giving. There is a complexity to Gregory's thought on gift which has not been adequately captured by either contemporary thinkers. With an understanding of giving which both enables and nullifies human generosity and calculation, and a construal of revelation as God's gift to creation by which one both receives and simultaneously endlessly seeks out a vision of the invisible, Gregory holds together in creative tension the very aspects which mark the difference between Milbank and Marion: economy and gratuitousness, participation and passive receptivity.     

TOWARD A MESSAGE-CENTERED THEORY OF PERSUASION: THREE EMPIRICAL INVESTIGATIONS OF LANGUAGE INTENSITY1

Based on accumulated knowledge concerning the effects of language intensity on attitude change, a set of propositions were advanced that provide a skeletal theoretical framework. Based on the propositions, three separate studies were done to extend the predictive power of the formulation. Predicted interactions between sex of the source, situational anxiety, source credibility, and language intensity were obtained. There were also significant person perception changes as a result of the level of language intensity employed in the persuasive message. Discussion centered on the import of the new findings in formulating a message-centered theory of persuasion.
