Structural Equation Modeling in Human-centric Computing Research: A Study of Electronic Communication in Virtual Teams Using WarpPLS. PowerPoint slides file
Structural equation modeling is a multivariate data analysis technique that allows researchers to concurrently analyze multiple relationships among manifest and latent variables. It can be particularly useful for computer science, human factors, and engineering researchers who need to understand the impact of technologies on people. Two main approaches to SEM exist: covariance-based and variance-based. Variance-based SEM has been gaining attention in the past several years due to its flexibility. Among other features, it performs well under deviations of multivariate normality, and generally requires smaller sample sizes than covariance-based SEM. This presentation discusses variance-based SEM in the context of a study of electronic communication in virtual teams. The software used is WarpPLS, developed by the presenter and available at warppls.com. WarpPLS is an easy-to-use variance-based SEM software that allows for the modeling of direct, mediating, and moderating effects among latent variables. WarpPLS also allows for the modeling and estimation of noncyclical (U or J curves) and mono-cyclical (S curves) nonlinear relationships among latent variables.

Scaring Them into Learning!? Using a Snake Screen to Enhance the Knowledge Transfer Effectiveness of a Web Interface. PowerPoint slides file
It seems that surprise events have the potential to turn short-term into long-term memories; an unusual phenomenon that may have limited but interesting applications in learning tasks. This surprise-enhanced cognition phenomenon is theoretically modeled based on the notion that many human mental traits have evolved through natural selection; a mathematical analysis building on Price’s covariance theorem is employed in this modeling effort. Additionally, the phenomenon is discussed in the context of an online learning task, based on a study involving 186 student participants. A simulated threat was incorporated into a human-computer interface with the goal of increasing the interface’s knowledge transfer effectiveness. The participants were asked to review Web-based learning modules and subsequently take a test on what they had learned. Data from 6 learning modules in 2 experimental conditions were contrasted. In the treatment condition a Web-based screen with a snake in attack position was used to surprise the participants; the snake screen was absent in the control condition. As predicted, the participants in the treatment condition did significantly better in the test for the modules immediately before and after the snake screen than the participants in the control condition. These findings are extrapolated to classroom applications in general. Ethical considerations are also discussed.
Costly Mate Choice Traits Should be Fairly Rare and Particularly Attractive to Members of the Opposite Sex. PowerPoint slides file
Costly mate choice traits are attractive traits that have a survival cost, where the cost presumably ensures that the traits are honest indicators of fitness to members of the opposite sex. This presentation suggests that costly traits used in mate choice by humans should be fairly rare and particularly attractive, more so than non-costly ones. Contrary to Zahavi’s handicap principle, however, it is argued here that mate choice traits do not always have to be costly to be reliable. These arguments build on a comparative mathematical analysis of the evolution of costly and non-costly mate choice traits. Price’s covariance equation is combined with Wright’s path analysis method, reducing the mathematical analysis to simple algebraic operations that can be understood and extended by evolutionary psychologists with limited mathematical training.
Using Surprise in Human-Computer Interfaces to Enhance Knowledge Communication Effectiveness. PowerPoint slides file
A study with 186 subjects is described in which a simulated threat was incorporated into a human-computer interface with the goal of increasing the interface’s knowledge communication effectiveness. The subjects were asked to review Web-based learning modules about International Commercial Terms (Incoterms), and subsequently take a test on what they had learned. Data from 6 learning modules in 2 experimental conditions were contrasted. In the treatment condition a Web-based screen with a snake in attack position was used to surprise the subjects; the snake screen was absent in the control condition. As predicted, the subjects in the treatment condition did significantly better in the test for the modules immediately before and after the snake screen than the subjects in the control condition; approximately 18 and 38 percent better, respectively.
MIS and Decision Science at TAMIU: The Department and its Programs. PowerPoint slides file
This presentation starts with a definition of the terms "MIS" and "decision science", and a discussion of the origins of MIS as a field of study aimed at looking into the impacts of information technologies on individuals and groups. The key differences between MIS and computer science are discussed. This is followed by a review of the programs offered by the Department of MIS and Decision Science at Texas A&M International University, which includes information on both major and minor (or concentration) programs. The presentation concludes with a discussion of career paths and accomplishments by former students.
The Scholar’s Curse. PDF file
Acceptance speech delivered on September 1, 2005 at the Texas A&M International University’s Fall Convocation Ceremony, for the Scholar of the Year Award. The speech argues that scholarly contributions are rarely recognized at the time they are made. It uses Darwin's theory of mutation, inheritance and selection of biological traits as an example.
An Extension and Test of the Communication Flow Optimization Model. PowerPoint slides file
This talk reports on a quasi-experimental action research study aimed at extending and testing the communication flow optimization model, which was developed as a result of a prior grant from the DoD’s External Acquisition Research Program. The test is aimed at demonstrating the generality of the model, which is argued to apply to non-defense as well as defense-related organizations. In the study, business process redesign groups in four different US organizations (not defense-related) used two different types of business process representation. The study suggests that, contrary to assumptions likely underlying most of the current business process redesign practice, communication flow-oriented representations of business processes are perceived by those involved in their redesign as significantly more accurate, more useful in the identification of opportunities for process improvement, more useful in the application of process redesign guidelines, more useful in the visualization of process changes, and more useful in the development of generic IT solutions to implement new business processes, than activity flow-oriented representations. The results are consistent with those obtained in similar empirical studies of business process redesign projects involving DoD branches and contractors.
The E-Collaboration Paradox: Evidence from Two Empirical Studies. PowerPoint slides file
This talk advances a new explanation for a set of mixed findings associated with academic and industry research on electronic collaboration during the last 30 years. Those mixed findings suggest, seemingly contradictorily, that: (a) people seem to consistently perceive face-to-face communication to pose fewer obstacles to effective communication than other, particularly electronic, media; and (b) when groups conduct collaborative tasks using electronic collaboration technologies they often present the same level of performance as groups accomplishing the same tasks face-to-face – which is paradoxical, in light of (a). This talk argues that the evolutionary history of humans suggests strongly that modern humans must have been largely “hardwired” for face-to-face communication, which explains our perceptions favoring the face-to-face medium. Nevertheless, the talk also argues that human beings, when faced with communication obstacles, invariably try to compensate for them by changing their behavior in relatively predictable ways, which often leads to no negative impact on task outcome quality. The explanatory power of these propositions is illustrated based on evidence from two empirical studies. The first is an experimental study of 20 business process redesign dyads, which employs parametric and nonparametric comparisons of means techniques for data analysis – ANOVA and Mann-Whitney U tests, respectively. The second is a survey study of 290 new product development teams, which employs structural equation modeling (PLS) techniques for data analysis.
Information Overload and National Culture: Assessing Hofstede’s Model Based on Data from Two Countries. PowerPoint slides file
This talk describes a study aimed at assessing Hofstede’s cultural dimensions model by comparing information overload perceptions in two countries, namely the US and New Zealand. The two countries are very close in terms of cultural dimension scores, and are part of the same country cluster in Hofstede’s model. Nevertheless, the two countries appear to differ significantly in terms of information overload perceptions, which is suggested by comparison of means and structural equation modeling analyses. While this finding is found to be consistent with the differences in cultural dimension scores between the US and New Zealand, especially in the power distance dimension, it seems to be inconsistent with those two countries being placed in the same country cluster.
Global Virtual Teamwork: Eight Key Empirical Findings and Related Conclusions. PowerPoint slides file
This talk discusses 8 key findings that have emerged from the analysis of over 860 business process redesign and new product development teams facilitated in three different countries. The teams used electronic communication technologies to different degrees when performing collaborative tasks. The findings refer to emerging concepts, such as that of a naturalness scale that can be used to categorize communication media, the degree of cognitive effort associated with different communication media, and the ability of different media to support the transfer of information and knowledge. Based on the discussion of the findings, some predictions are made regarding the impact of electronic communication tools on global virtual teams in general.
