Surviving Y2K in mainframe enterprise computing
Article Abstract:
The Year 2000 problem will mostly affect mainframe-based systems. Companies can deal with this problem if they are sufficiently aware of the technical causes of this date processing problem. One of the causes of the Y2K problem is that year dates for the 21st century will be mishandled on many systems. In addition, the fact that 2000 will be a leap year is expected to further exacerbate the matter. Hardware and system level problems also contribute to this problem. A six-step program is recommended to combat the Year 2000 problem. The steps involved in this solution are cost/benefit analysis, impact analysis, correction of the problem, correction of hardware and system problems, compliance testing of in-house systems and compliance testing of external interfaces.

How to handle multicollinearity in regression modeling
Article Abstract:
Multicollinearity poses drawbacks in interpreting the relative significance of independent variables, thus affecting the quality of forecasts. Multicollinearity refers to the existence of a linear relationship among some of the independent variables, which goes against one of the three fundamental assumptions in regression modeling. It states that the independent variables in the model do not have a linear relationship. While there is no standard approach in solving the problem of multicollinearity, some remedial measures can be taken to deal with it. These are transforming variables by differencing, incorporating a priori information into the model, dropping a variable/variables from the model and adding new or additional sample data.

Preparing to handle dilemmas in the computing profession
Article Abstract:
Most organisations are becoming increasingly dependent on computer technology and the builders of such systems are often faced with moral and ethical dilemmas that must be resolved. Formal training in responsible conduct should be available for computer professionals and informal support needs to be available to raise awareness of ethical issues.
