Internet crime has become increasingly dependent on the underground economy: a loose federation of specialists selling capabilities, services, and resources explicitly tailored to the abuse ecosystem. Through these emerging markets, modern criminal entrepreneurs piece together dozens of à la carte components into entirely new criminal endeavors. From an abuse fighting perspective, criminal reli...

It has been 10 years since Randy Garrison, Terry Anderson and Walter Archer (2000) first introduced the Community of Inquiry (CoI) model. As recounted in the first article in this special issue, the CoI framework was developed to help them make sense of issues confronting their new online graduate program, a program in which computerbased discussion forums played a central role. Because the ped...

Control charts are widely used for process monitoring. They show whether the variation is due to common causes or whether some of the variation is due to special causes. To detect large shifts in the process, Shewhart-type control charts are preferred. Cumulative sum (CUSUM) and exponentially weightedmoving average (EWMA) control charts are generally used to detect small and moderate shifts. Sh...

Control charts are extensively used in processes and are very helpful in determining the special cause variations so that a timely action may be taken to eliminate them. One of the charting procedures is the Shewhart-type control charts, which are used mainly to detect large shifts. Two alternatives to the Shewhart-type control charts are the cumulative (CUSUM) control charts and the exponentia...
