Associations between user training and information systems success

What type and amount of computer-related training are available to information system (IS) users? And, how do these relate to their (users) perceptions of the success of the systems used? This paper reports on a study designed to answer such questions. Data were collected from 98 IS users in 16 different departments of 12 organizations. The results indicate that there exist positive associations between various types of computer-related training/educational programmes an organization provides to IS users and the perceived success of IS. Specifically, the availability of a computer resident expert in the organizational functional area of users has the most significant positive relationship with success.     

Gas between the stars

The interstellar gas in galaxies is heated by stellar radiation and cosmic rays and it also cools through radiation. We take a detailed look at these processes in order to understand the thermal state of equilibrium of the interstellar gas. This gas also manifests itself in different ‘phases’–molecular, neutral atomic and ionized, each with its characteristic temperature and density, which we attempt to understand.
