Computer software similarities play important roles in users’ skills transfer from one application to another. Despite common software attributes recognized in extant literature, a systematic understanding of the components and structure of software similarities has not been fully developed. To address the issue, a Delphi study was conducted to explore the underlying dimensions of software simi...

With the emergence of eTextbooks initiatives on the rise, it is promising that eTextbooks support significant opportunities for improving the educational practices. However, there are both positive and negative reports of using eTextbooks in the academic setting. This study was aimed at exploring the concept of eTextbooks by confirming the opinions from stakeholders on the features and function...

In this study, a Delphi method was used to identify and predict the roles of blended learning approaches in computer-supported collaborative learning (CSCL) environments. The Delphi panel consisted of experts in online learning from different geographic regions of the world. This study discusses findings related to (a) pros and cons of blended learning approaches in CSCL; (b) blended learning f...

The ranking-type Delphi method is well suited as a means for consensus-building by using a series of questionnaires to collect data from a panel of geographically dispersed participants. This method allows a group of experts to systematically approach a particular task or problem. While information systems researchers have been using this method for almost three decades, no research to date has...

This paper discusses the notion of collective intelligence through the application of the Wideband Delphi method as a way to obtain convergence among a group of experts. The specific application is the definition and calibration of cost estimation models that use data collected from experts as part of their calibration. Convergence is important in this case because companies need to commit to c...

Delphi is a source-code analysis and manipulation system being developed to analyze and transform Bricklayer programs. The information obtained from Delphi analysis can be used to generate problemspecific text in the form of a mini-lecture. This opens the door to the automated integration of such texts with commercial animation software and textto-speech (TTS) tools. The result is a scalable in...

Article history: Received 14 September 2010 Received in revised form 31 March 2011 Accepted 6 April 2011 Available online 20 May 2011 The cornerstone of good research is establishing integrity. However, identifying and gauging methodological rigour for the Delphi technique remains elusive. This is due to a number of reasons such as the ongoing epistemological debate, along with continual modifi...

The popularity of mobile devices has stimulated rapid progress in both Wi-Fi and cellular technologies. Before LTE was widely deployed, Wi-Fi speeds dominated cellular network speeds. But that is no longer true today. In a study we conducted with a crowd-sourced measurement tool used by over 1,000 users in 16 countries, we found that 40% of the time LTE outperforms Wi-Fi, and 75% of the time th...

A software for the thermal and hydraulic design of shell and tube heat exchangers with flowinduced vibration checks has been developed in a Windows-based Delphi programming environment. Its user-friendly input format and excellent colour graphics features make it an excellent tool for the teaching, learning and preliminary design of shell and tube heat exchangers. Design methodology is based on...
