Characteristics Of A Multi-User Tutoring Architecture, Stephen B. Gilbert, Eliot H. Winer, Joseph Holub, Trevor Richardson, Michael C. Dorneich, Michael Hoffman 2017 Iowa State University

Characteristics Of A Multi-User Tutoring Architecture, Stephen B. Gilbert, Eliot H. Winer, Joseph Holub, Trevor Richardson, Michael C. Dorneich, Michael Hoffman

Stephen B. Gilbert

Intelligent tutor systems have been quite successful in instruction of individuals (Koedinger, Anderson, Hadley, & Mark, 1997; Ritter, Kulikowich, Lei, McGuire, & Morgan, 2007; Vanlehn, et al., 2005), but multiple challenges exist when attempting to tutor a team. Sottilare, Holden, Brawner, and Goldberg (2011) describe some of the architectural challenges of team tutoring at a high level in terms of functional requirements. In this paper we describe specific challenges in terms of implementing a team architecture within the Generalized Intelligent Framework for Tutoring (GIFT), including simultaneous startup and synchronization with distributed team members, maintaining state of multiple users, and timing feedback for teams and individuals appropriately.


Community-Engaged Operations Research: Trends, New Frontiers And Opportunities, Michael P. Johnson Jr. 2017 University of Massachusetts - Boston

Community-Engaged Operations Research: Trends, New Frontiers And Opportunities, Michael P. Johnson Jr.

Michael P. Johnson

Scholars in multiple disciplines intersecting operations research have developed theory and applications to address the question, how can the decision sciences develop new ways to solve problems of special interest to organizations and individuals situated in geographically, economically and socially circumscribed communities? The motivation for this work is the belief that mission-driven and resource-constrained nonprofit organizations, and underrepresented, underserved, or vulnerable populations may have special needs for analytic and empirical problem-solving methods that have traditionally received less emphasis in traditional operations research and management science research and teaching. Scholarship in this area, alternatively labeled ‘community operational research’ (mostly in the ...

Emerging Trends And New Frontiers In Community Operational Research, Michael P. Johnson Jr., Gerald Midgley, George Chichirau

Michael P. Johnson

Community operational research (COR), and its disciplinary relation, community-based operations research, have an increasingly high profile within multiple domains that benefit from empirical and analytic approaches to problem solving. Many of these areas, as represented by papers in this special issue, are concentrated in human services, community and economic development, education and other non-profit services, and the nature of inquiry tends to be motivated by action research and systems thinking as much as traditional decision modeling. However, there are many other areas of inquiry in which COR has had only a modest presence to date. This paper identifies a number ...

The advent of smart grids with enhanced data communication capabilities propels DR to be an essential part of the next generation power distribution system. Fundamentally, DR has the ability to charge a customer the true price of electricity at the time of use, and the general perception is that consumers would shift their load ...


Optimization Models And Algorithms For Demand Response In Smart Grid., Guangyang Xu 2016 University of Louisville

Optimization Models And Algorithms For Demand Response In Smart Grid., Guangyang Xu

Electronic Theses and Dissertations

For demand response in smart grid, a utility company wants to minimize total electricity cost and end users want to maximize their own utility. The latter is considered to consist of two parts in this research: electricity cost and convenience/comfort. We first develop a system optimal (SO) model and a user equilibrium (UE) model for the utility company and end users, respectively and compare the difference of the two. We consider users' possible preference on convenience over cost-saving under the real-time pricing in smart grid, and each user is assumed to have a preferred time window for using a ...

Improvement Of Work Process Performance With Task Assignments And Mental Workload Balancing, Cansu Kandemir 2016 Old Dominion University

Improvement Of Work Process Performance With Task Assignments And Mental Workload Balancing, Cansu Kandemir

Engineering Management & Systems Engineering Theses & Dissertations

The outcome of a work process depends heavily on which tasks assigned to which employees. However, sometimes-optimized assignments based on employees’ qualifications may result in an uneven and ineffective workload distribution among them. Likewise, an even workload distribution without considering the employee's qualifications may cause unproductive employee-task matching that results in low performance of employees. This trade-off is even more noticeable for work processes during critical time junctions, such as in military command centers and emergency rooms that require being fast and effective without making errors.

This study proposes that optimizing task-employee assignments according to their capabilities while also ...

Homcam: A Wireless 360-Degree Wearable Streaming Camera For Remote Situational Awareness, Brian Peck, Stephen Gilbert, Eliot Winer, Robert Ray

Industrial and Manufacturing Systems Engineering Conference Proceedings and Posters

The growth of mobile and wearable technologies has enabled a host of new applications, including remote situational awareness, in which a device worn by a remote partner can simulate being present in the remote location for an observer. We illustrate this idea by constructing the HomCam, a helmet-based omnidirectional video system that gives an observer the 360-degree perspective of a remote wearer. To our knowledge, the HomCam was the first wearable system that enabled real-time streaming of 360-degree video to a remote location built from commercial-of-the-shelf hardware. This paper describes related efforts, the HomCam prototype, its visual display, and an ...

Politeness In Machine-Human And Human-Human Interaction, Joachim Meyer, Chris Miller, Peter Hancock, Ewart De Visser, Michael Dorneich

Industrial and Manufacturing Systems Engineering Conference Proceedings and Posters

Computers communicate with humans in ways that increasingly resemble interactions between humans.Nuances in expression and responses to human behavior become more sophisticated, and they approachthose of human-human interaction. The question arises whether we want systems eventually to behave likehumans, or whether systems should, even when much more developed, still adhere to rules that aredifferent from the rules governing interpersonal communication. The panel addresses this issue fromvarious perspectives, eventually aiming to gain some insights into the question of the direction to which thedevelopment of machine-human communication and the etiquette implemented in the systems shouldmove.

Development Of An Associate Degree Level Course On Lean, Jeremy Espinoza

Master of Technology Management Plan II Graduate Projects

Lean training and education has become a focal point in both industry and the realm of academics; however, the need within the industry remains, and oftentimes companies must take on the additional and high expense of training new graduates once they enter the workforce. Often, the classes that students study in the lean methodology, if any are studied at all, are taught within other disciplines, and the instruction is in a general sense as opposed to in depth and hands on. Within the past eight years it has been referenced in different academic articles that students are not coming into ...

An Empirical Investigation On Ceo Turnover In It Firms And Firm Performance, Peiqin Zhang, David Wierschem, Francis A. Mendez Mediavilla, Keejae P. Hong

Journal of International Technology and Information Management

Drawn upon upper echelon theory and organizational theory, this research proposes to examine the impact of CEO turnover in IT firms on firm performance in terms of both sustainable accounting performance and market performance. We find that CEO turnover is a significant determinant of firm performance, especially in IT firms. This paper contributes to the IS literature by investigating the CEO turnover impact in IT firms compared to other industries. This study also has practical implications by providing the guideline for IT firms on the CEO turnover policy. Such firms should place additional emphasis on their succession planning efforts.
