Using Content Analysis to Understand the Consumer Movement

Drawing on the work of Jenkins and Perrow, a content analysis of information in the New York Times Index is examined to analyze the environment of the consumer movement in the United States over a fourteen-year period. The results suggest that a fundamental change has occurred in the movement, with less visible activism and less overt business support being provided.     

ERROR-CORRECTION, ⇐ SURPRISE ⇒ MODELS AND THE DIFFERENTIAL APPROACH TO THE CONSUMPTION FUNCTION(*)

The paper provides a general theoretical framework that allows a comparison and a possible reconciliation of error correction models of consumers’behaviour and the life cycle hypothesis under rational expectations. It is suggested that by relaxing the assumption of intertemporally strongly separable and homothetic preferences, a generalization of Hall's random walk model can be derived, containing an error correction mechanism.     

The R&D Effectiveness Index: A Metric for Product Development Performance

Measuring the overall success of product development efforts has been frustrating because there is no generally recognized metric to measure effectiveness. The R&D Effectiveness Index is introduced to address this need. It measures effectiveness by comparing the profit from new products to the investment in new product development. The article provides the details for calculating the index along with alternative interpretations. Michael McGrath and Michael Romeri report that this index was validated through a study of 45 electronic systems companies. They found a strong relationship between the R&D Effectiveness Index and other performance factors and believe that the R&D Effectiveness Index can be used to compare performance, measure improvement, and evaluate business units. Its application is illustrated in a case study.     

Correlation of acid gas-ethanolamine equilibrium using ionic concentrations

Experimental equilibrium measurements are modeled using a Davies-like ionic strength correction term for the reaction equilibrium constants. Calculated and experimental results are in much better agreement when the ionic strength correction terms are used.
