Economies have grown where innovative dynamism has flourished, especially in the United States from roughly 1830 to 1930. Innovations are not inevitable, but occur when inventors can invent and entrepreneurs can innovate. Individual inventors matter and are scarce. Thomas Edison was not the only one to invent a light bulb but was the first to invent a bulb that would stay lit at a price that ordinary people could afford. Leapfrog competition occurs when an innovation improves on, and at least partly replaces, an older technology. The best size for a firm varies with technology, industry, and business model. With John D. Rockefeller’s process innovations, Standard Oil succeeded as a big firm. But horizontal mergers failed in many other industries during the same period. Big incumbent firms can implement innovations, but are disadvantaged at starting breakthrough innovations. Baldwin Locomotive and Netscape illustrate that firms can contribute and then exit with honor.

Natural Means

Water tables in aquifer regions of the southwest United States are dropping off at a rate which is greater than can be replaced by natural means. It is estimated that by 1985 wells will run dry in this region unless adequate artificial recharging can be accomplished. Recharging with surface water is limited by the plugging of permeable rock formations underground by clay particles and organic debris.A controlled study was initiated in which sand grains were used as the rock formation and water with known clay concentrations as the recharge media. The plugging mechanism was investigated by direct observation in the SEM of frozen hydrated sand samples from selected depths.

Prostate adenocarcinoma is the most common malignant tumor of men in the United States and is the third leading cause of death in men. Despite attempts at early detection, there will be 244,000 new cases and 44,000 deaths from the disease in the United States in 1995. Therapeutic progress against this disease is hindered by an incomplete understanding of prostate epithelial cell biology, the availability of human tissues for in vitro experimentation, slow dissemination of information between prostate cancer research teams and the increasing pressure to “ stretch” research dollars at the same time staff reductions are occurring.To meet these challenges, we have used the correlative microscopy (CM) and client/server (C/S) computing to increase productivity while decreasing costs. Critical elements of our program are as follows:1) Establishing the Western Pennsylvania Genitourinary (GU) Tissue Bank which includes >100 prostates from patients with prostate adenocarcinoma as well as >20 normal prostates from transplant organ donors.
