IPAD: A unique approach to government/industry cooperation for technology development and transfer

A key element to improved industry productivity is effective management of Computer Aided Design / Computer Aided Manufacturing (CAD/CAM) information. To stimulate advancement, a unique joint government/industry project designated Integrated Programs for Aerospace-Vehicle Design (IPAD) was carried out from 1971 to 1984. The goal was to raise aerospace industry productivity through advancement of computer based technology to integrate and manage information involved in the design and manufacturing process. IPAD research was guided by an Industry Technical Advisory Board (ITAB) composed of over 100 representatives from aerospace and computer companies. The project complemented traditional NASA/DOD research to develop aerospace design technology and the Air Force's Integrated Computer Aided Manufacturing (ICAM) program to advance CAM technology. IPAD had unprecedented industry support and involvement and served as a unique approach to government industry cooperation in the development and transfer of advanced technology. The IPAD project background, approach, accomplishments, industry involvement, technology transfer mechanisms and lessons learned are summarized

Factorization is not violated

We show that existing proofs of factorization imply the cancellation of certain multiladder contributions that Gotsman, Levin, and Maor had suggested would invalidate the basic factorization theorem in QCD. No modifications of the original argument are necessary, although the details of the example offer useful insight into the mechanisms of factorization.Comment: 11 pages including 10 figure

The New Old Legal Realism

Do the decisions of appellate courts matter in the real world? The American judicial system, legal education, and academic scholarship are premised on the view that they do. The authors want to reexamine this question by taking the approach advocated by the original Legal Realists. The current project seeks to add to our knowledge of the relevance of case law by focusing on an area that has received little examination: how pronouncements about employment discrimination law by appellate courts translate into understandings and behavior at the ground level. As our lens, we use evidence of how people talk about the relevance of changes in the law. This new Old Legal Realist perspective suggests that social and economic factors play a more important role than case law in outcomes on the ground. Cases cannot have an impact, if the local social and economic variables are not aligned in a fashion that allows the impact to occur

The inflation-productivity trade-off revisited

Our aim in this paper is threefold. First, to test the robustness of the relation between total factor productivity growth and inflation to the specification of the estimating model; second, to test the stability of their relationship in the short run and in the long run, and third, to investigate the direction of causality between these two variables. To accomplish the first objective, we esti-mate a generalized Box-Box cost function using data from the two-digit Standard Industrial Clas- sification of manufacturing industries in Greece during the period 1964- 1980. The results show that: a) the acceleration of inflation from 1964- 1972 to 1973-1980 reduced total factor productiv-ity growth in a way that was both statistically significant and sizeable, and b) even when the ef-fect of inflation is separated from the effects of technical change and economies of scale, the choice of functional form is most crucial. With respect to the second objective, somewhat to our surprise, we find that the inflation-productivity trade-off prevails even in the long run. And, fi-nally, regarding the third objective, it emerges that in the great majority of two-digit manufactur-ing industries the causality runs from inflation to productivity. On these grounds we conclude that for a precise estimation of the relationship under consideration it is imperative to sort out the three effects involved, do so by adopting the most general flexible functional form for the cost function, and run the appropriate stability and causality tests.inflation; productivity; scale economies; technical change; generalized Box-Cox cost function; stability; causality
