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.  相似文献

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.  相似文献

The functional approach to improving communication strategy has received little attention. This research attempts to partially correct this oversight by experimentally verifying the major functional hypothesis: matching message with functional profile brings about attitude change. Working adults were integrated into an experiment which was a before-after with control. The major functional hypothesis was confirmed at the 0.10 level. An associated hypothesis regarding the relative ease of changing value- expressive attitudes compared to utilitarian attitudes was confirmed at the 0.10 level. The results show the importance of matching message with functional profile and highlight the potential inherent in the functional approach.  相似文献

This paper analyzes the money stock effects of the Monetary Control Act (MCA) under a nonborrowed reserve (NBR) operating procedure. Prior to the passage of the MCA, policy was conducted under an interest rate operating target where reserve requirement reforms such as those introduced by the MCA had little influence on money stock variability. Under an NBR procedure however, the structure of reserve requirements may have a significant impact on monetary control. Our analysis indicates that the relative improvement in monetary control greatly depends on the degree of tightness exercised by the Federal Reserve over total reserves in an MCA regime. The tighter the control, the more significant the estimated monetary control benefits of the MCA under an NBR procedure.  相似文献

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.  相似文献

Risk associated with the adoption of new maize technology and the impact of mandatory cotton production on traditional farmers in the Kasai Oriental Region of Zaire are evaluated within a portfolio context using a quadratic programming model. Seasonal net returns for farm plans including four levels of maize technology in combination with staple food crops are evaluated, with and without mandatory cotton production. The results indicate that cropping systems that include new maize technology are risk-efficient relative to local maize varieties while mandatory cotton production is not risk-efficient at the prevalent price and yield levels in the farming system.  相似文献

In September 1973, the President of the World Bank, Robert S. McNamara, made a challenging address to the Governors of the Central Banks of the member states of the international Monetary Fund. The main subject in his speech was the problem of poverty particularly in rural areas of developing countries, and the design for a strategy for its abolition.  相似文献
