Topologies on Complete Lattices

One of the more important concepts in mathematics is the concept of order, that is, the description or comparison of two elements of a set in terms of one preceding or being smaller than or equal to the other. If the elements of a set, as pairs, exhibit certain order-type characteristics, the set is said to be a partially ordered set. The purpose of this paper is to investigate a special class of partially ordered sets, called lattices, and to investigate topologies induced on these lattices b… more

Reactions and Learning as Predictors of Job Performance in a United States Air Force Technical Training Program

This study is based on Kirkpatrick's (1996) four level evaluation model. The study assessed the correlation between and among three levels of data that resulted from evaluation processes used in the U.S. Air Force technical training. The three levels of evaluation included trainee reaction (Level 1), test scores (Level 2), and job performance (Level 3). Level 1 data was obtained from the results of a 20 item survey that employed a 5-point Likert scale rating. Written test scores were used for L… more

Relationship Between Flow Experience, Flow Dimensions, and the Equivalence of Challenges and Skills in the Web-Based Training Environment

This study applied components of Csikszentmhalyis flow theory to the Web-based Training (WBT) environment. Specifically considered were how the equivalence of a learners perceived challenges and skills for an activity can effectively predict the emergence of flow in the WBT environment. Also considered was the ability of flow dimensions defined in flow theory to predict and model the occurrence of flow during WBT activities. Over a period of about one hour, students (n=43) from a southwes… more

Performance Measurement, Feedback, and Reward Processes in Research and Development Work Teams: Effects on Perceptions of Performance

Organizations have had difficulty managing the performance of their knowledge work teams. Many of these troubles have been linked to antiquated or inadequate performance management systems along with a scarcity of empirical research on this important human resource initiative. These problems are magnified when managing the performance of research and development teams because greater ambiguity and uncertainty exists in these environments, while projects are unique and continually evolving. In a… more

Equivalency of paper-pencil tests and computer-administered tests.

Are computer-administered versions of a multiple choice paper-pencil test equivalent? This study determined whether there were any significant differences between taking a traditional pencil-paper test and taking the same test using a computer. The literature has shown that there are intervening variables that have caused differences when not controlled. To prove equivalency between test modes, scores have to have similar means, dispersions, and shapes; the ranked-order of the scores must also … more
