Learning African-American History In A Synthetic Learning Environment, Adams Greenwood-Ericksen
Electronic Theses and Dissertations
Synthetic Learning Environments (SLEs) represent a hybrid of simulations and games, and in addition to their pedagogical content, rely on elements of story and interactivity to drive engagement with the learning material. The present work examined the differential impact of varying levels of story and interactivity on learning. The 2x2 between subjects design tested learning and retention among 4 different groups of participants, each receiving one of the 4 possible combinations of low and high levels of story and interactivity. Objective assessments of participant performance yielded the unexpected finding that learners using the SLE performed more poorly than any other …
Controlling Our Emotion At Work: Implications For Interpersonal And Cognitive Task Performance In A Customer Service Simulation, Moshe Feldman
Controlling Our Emotion At Work: Implications For Interpersonal And Cognitive Task Performance In A Customer Service Simulation, Moshe Feldman
Electronic Theses and Dissertations
Display rules are used by organizations to define appropriate behaviors and expressions while interacting with others in the workplace. Emotional labor is a function of the effort required to adhere to these display rules and has been associated with negative outcomes such as stress and burnout which can lead to higher levels of turnover and health care costs for the organization. In addition, evidence suggests that emotional labor may come at a cognitive cost as well. Hence, reducing the amount of emotional labor should be beneficial to both employees and organizations alike. The current study used a customer service simulation …

Effect Of Operator Control Configuration On Unmanned Aerial System Trainability, John Neumann
Effect Of Operator Control Configuration On Unmanned Aerial System Trainability, John Neumann
Electronic Theses and Dissertations
Unmanned aerial systems (UAS) carry no pilot on board, yet they still require live operators to handle critical functions such as mission planning and execution. Humans also interpret the sensor information provided by these platforms. This applies to all classes of unmanned aerial vehicles (UAV's), including the smaller portable systems used for gathering real-time reconnaissance during military operations in urban terrain. The need to quickly and reliably train soldiers to control small UAS operations demands that the human-system interface be intuitive and easy to master. In this study, participants completed a series of tests of spatial ability and were then …

Right Turn Split: A New Design To Alleviate Weaving On Arterial Streets, Khaled Shaaban
Electronic Theses and Dissertations
While weaving maneuvers occur on every type of roadway, most studies have focused on freeway maneuvers. Weaving occurring on non-freeway facilities, such as arterial streets, can cause significant operational problems. Arterial streets weaving typically occur when vehicles coming from a side street at an upstream intersection attempt to enter the main street from one side to reach access points on the opposite site at a downstream intersection by crossing one or more lanes. This dissertation investigates the type of problems occurring on arterial streets due to the weaving movements and recommends a new design to alleviate weaving on arterial streets. …
Modeling And Simulation Of Long Term Degradation And Lifetime Of Deep-Submicron Mos Device And Circuit, Zhi Cui
Electronic Theses and Dissertations
Long-term hot-carrier induced degradation of MOS devices has become more severe as the device size continues to scale down to submicron range. In our work, a simple yet effective method has been developed to provide the degradation laws with a better predictability. The method can be easily augmented into any of the existing degradation laws without requiring additional algorithm. With more accurate extrapolation method, we present a direct and accurate approach to modeling empirically the 0.18-ìm MOS reliability, which can predict the MOS lifetime as a function of drain voltage and channel length.

Measuring The Effect Of Erratic Demandon Simulated Multi-Channel Manuf, Nancy Kohan
Measuring The Effect Of Erratic Demandon Simulated Multi-Channel Manuf, Nancy Kohan
Electronic Theses and Dissertations
To handle uncertainties and variabilities in production demands, many manufacturing companies have adopted different strategies, such as varying quoted lead time, rejecting orders, increasing stock or inventory levels, and implementing volume flexibility. Make-to-stock (MTS) systems are designed to offer zero lead time by providing an inventory buffer for the organizations, but they are costly and involve risks such as obsolescence and wasted expenditures. The main concern of make-to-order (MTO) systems is eliminating inventories and reducing the non-value-added processes and wastes; however, these systems are based on the assumption that the manufacturing environments and customers' demand are deterministic. Research shows that …
