A vast body of empirical studies lends support to the incentive effects of rankorder tournaments. Evidence comes from experiments in laboratories and non-experimental studies exploiting sports or firm data. Selection of competitors across tournaments may bias these non-experimental studies, whereas short task duration or lack of distracters may limit the external validity of results obtained in...

Three operational test events from separate ACAT 1D acquisition programs are the foundation for this study. The generalized effect of the software systems on individual test results is examined. The test results support discussions related to several current test and evaluation (T&E) initiatives such as early integrated testing, cost reduction by sharing high-demand testing assets, and mission-...

A student’s problem solving ability (PSA) is often considered a factor in determining their success in a first course in computer programming (CS1). Can a student’s PSA be measured before taking a CS1 course? How? Would such an assessment effectively predict final exam scores? This paper presents the results of a pilot study guiding the development of a PSA assessment method. The approach attem...

Objective: This study was designed to compare the efficacy of simulator-based VRSim TEE training system and web-based virtual TEE program in training anesthetic residents. Methods: 28 second-year anesthetic trainees with no record of TEE experience were randomly assigned to two groups: simulator group and e-learning group. The simulator group undertaken training via simulator-based VRSim TEE tr...

These notes record seven lectures given in the computer algebra course in the fall of 2004. The theory of subresultants is not required for the final exam due to its complicated constructions. 1 Chinese remainder algorithm 1.1 Modular arithmetic Let m be a positive integer greater than one. We discuss basic operations in Z/(m). The elements in Z/(m) can be represented in two ways: • {0, 1, . . ...

Anyone who has taught an introductory ethics course or a professional ethics class has likely heard students writing off ethics and ethics instruction as unimportant, offering as evidence some type of moral relativism. Even if the instructor is sympathetic towards a particular version of moral relativism, students’ relativist claims can be disconcerting and can seriously detract from their will...

With the literature calling for comparisons among technology-enhanced or active-learning pedagogies, a blended versus flipped instructional comparison was made for numerical methods coursework using three engineering schools with diverse student demographics. This study contributes to needed comparisons of enhanced instructional approaches in STEM and presents a rigorous and adaptable methodolo...

The increases in the number of online courses given by universities have been quite dramatic over the last couple of years. Nowadays, many universities even give complete degree programs online where instructions and lectures in the form of, for example, streaming videos, are available for students to watch 24 hours a day. In a sense, the use of Internet and Interactive Computer Technologies (I...

This paper examines how grade incentives affect student learning across a variety of ourses at two universities, using for identification the discrete rewards offered by the standard A-F letter grade system. We develop five predictions about effort provision in the presence of the thresholds that separate these discrete rewards, only one of which has been previously tested in the economics lite...
