Structural constraints on organizational change: A longitudinal analysis

The results of a longitudinal study assessing the impact of internal constraints upon both organizational responsiveness to the environment and efforts to change structures for symbolic signaling of policy are presented. The causal model used is developed from a theoretical elaboration of Williamson, Thompson, and Meyer. The implications of the analysis for the signaling metaphor of organizational change are emphasized. The data indicate (i) that the varying resistance to change observed within core dimensions of organizational structure may be largely due to durable capital investments, (ii) that within capitalized dimensions of organizational structure, the resulting resistance to change leads to a longitudinal persistence of centralized decision making, and (iii) that failure to incorporate such constraints in analyses of organizational change leads to misleading results.     

Humor and cognitive responses to advertising stimuli: A trace consolidation approach

Despite the predictions of several attitude change theories, most empirical research suggests that humorous communications are no more persuasive than their serious counterparts. The present study adopted a trace consolidation theory approach and tested the hypothesis that humorous appeals are more persuasive than serious appeals when time for trace consolidation is allowed. The trace consolidation theory hypothesis was supported most directly by shifts in cognitive responses. On some measures, sex differences were also observed. Specifically, males were found to be more susceptible than females to the humorous persuasive appeal.     

Of lessees,lessors, and discount rates and whether pigs have wings

Recent articles on leasing suggest five principles that should aid analysts to understand this durable, much misunderstood financial instrument. The principles are 1) the lessor must be happy too, 2) the operating inflows have nothing to do with the case, 3) financial, like physical, matter tends to be preserved, 4) debt is a function of after-tax flows, and 5) inability to use tax shelters cuts two ways. In this paper we illustrate these principles and use illustrations to demonstrate that each of these principles has merit. We argue as well that the impression, often left by the principles, that leasing seldom benefits all parties to the transaction is incorrect.     

A new release of the ASTM CHETAH program for hazard evaluation: Versions for mainframe and personal computer

CHETAH, which stands for the Chemical Thermodynamic and Energy Release Program, was introduced in 1974. Since then, the CHETAH program has been widely used in the chemical industry for hazard evaluation. Although its chief aim is to predict deflagration/detonation potential from molecular structure, it can also be used to estimate heats of reaction, heat capacities, and entropies. One of the limitations of the original program was its rigid, punched card oriented format for data input and the lack of an overall hazard rating derived from the several hazard criteria. A new release of this program alleviates these shortcomings and includes other improvements. The main features of the new release are: 1) a totally interactive front end, 2) an interpreter subroutine which uses sophisticated pattern recognition techniques to combine the four hazard criteria into an overall hazard rating, 3) recognition of certain atomic groupings which are known to be sensitive, 4) correct handling of the symmetry number, and 5) an updated data bank. One of the most important features of this release is its availability in an IBM PC compatible version, making the program accessible to more users.
