In large organizations, typical systems portfolios consist of a mix of legacy systems, proprietary applications, databases, off-the-shelf packages, and client-server systems. Software systems integration is always an important issue and yet a very complex and difficult area in practice. Consider the software integration between two organizations on a supply chain; the level of complexity and difficulty multiply quickly. How to make heterogeneous systems work with each other within an enterprise or across the Internet is of paramount interest to businesses and industry.

The skill-sets of many information technology (IT) professionals are becoming obsolete as IT changes accelerate. Organizations are retraining many software developers with legacy systems skills to skills required in the new Internet-based, client-server and object-oriented paradigms. This type of retraining is not incremental, but entails major cognitive, methodological and procedural shifts. Given its importance, cost and currency, processes that impact the effectiveness of training should be considered. Trainee motivation is one such process that should be investigated because it is more malleable than other aspects, such as trainees’ cognitive ability. This chapter proposes a model of motivational intentions and antecedents in this information technology retraining context. Theoretical background for the model is described. In addition, the implications of the model and its potential utilization in influencing motivational intentions, and ultimately improving the retraining outcomes, is discussed.

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.
