14. Investigating Cybersecurity Issues In Active Traffic Management Systems

Abstract

Active Traffic Management (ATM) systems have been introduced by transportation agencies to manage recurrent and non-recurrent congestion. ATM systems rely on the interconnectivity of components made possible by wired and/or wireless networks. Unfortunately, this connectivity that supports ATM systems also provides potential system access points that results in vulnerability to cyberattacks. This is becoming more pronounced as ATM systems begin to integrate internet of things (IoT) devices. Hence, there is a need to rigorously evaluate ATM systems for cyberattack vulnerabilities, and explore design concepts that provide stability and graceful degradation in the face of cyberattacks. In this research, a prototype ATM system along with a real-time cyberattack monitoring system were developed for a 1.5-mile section of I-66 in Northern Virginia. The monitoring system detects deviation from expected operation of an ATM system by comparing lane control states generated by the ATM system with lane control states deemed most likely by the monitoring system. In case of any deviation between two sets of states, the monitoring system displays the lane control states generated by the back-up data source. In a simulation experiment, the prototype ATM system and cyberattack monitoring system were subject to emulated cyberattacks. The evaluation results showed that when subject to cyberattack, the mean speed reduced by 15% compared to the case with the ATM system and was similar to the baseline case. This illustrates that the effectiveness of the ATM system was negated by cyberattacks. The monitoring system however, allowed the ATM system to revert to an expected safe state and reduced the negative impact of cyberattacks. These results illustrate the need to revisit ATM system design concepts as a means to protect against cyberattacks in addition to traditional system intrusion prevention approaches., Comment: 25 pages,7 figures, Accepted for Publication in Transportation Research Record, Journal of Transportation Research Board 2018

16. Motivation in Gamified Social Media Learning: A Psychological Need Perspective

Author

Ofosu-Ampong, Kingsley, Boateng, Richard, Kolog, Emmanuel A., and Anning-Dorson, Thomas

Abstract

With a high attrition rate among students in online learning, educators and researchers have introduced gamified social media learning platforms which allow students to share their experiences, co-create knowledge, and collaboratively learn about computing principles. However, only a few studies have examined learners' motivations, antecedents, and consequences on a gamified social learning platform. This study draws on the self-determination theory to test a proposed model for gamification users in computing education. Participants were undergraduate students who completed an online survey during the semester on a course design project. This course aims to prepare students to undertake a significant piece of individual work on a design project and appreciate the appropriate techniques in managing information technology projects. Interestingly, the study found a non-significant relationship between game rewards and how they improve competence. The results expand our understanding of pedagogical strategies and innovation open to education institutions.

20. Are We Ready for Gamification? An Exploratory Analysis in a Developing Country

Author

Ofosu-Ampong, Kingsley, Boateng, Richard, Anning-Dorson, Thomas, and Kolog, Emmanuel A.

Abstract

Integrating gamification in the learning process has become a significant factor in the success of teaching, learning, and research in higher education. Education can leverage gamification by enhancing learning management systems to make learning enjoyable and engaging for students. We, however, lack the underpinnings into factors affecting the acceptance of gamification in education. To help solve this, we tested and extended previous acceptance models. Overall, we explored the users' perception and acceptance of adding gamification to learning among students in higher education. The results show that Image is an insignificant factor in students' behavioral intention to use gamification. The current paper contributes to the perceptual process for gamification research in learning; deriving implications for gamification application and pioneering research on gamification acceptance in developing countries. We conclude with opportunities, practical and theoretical implications for researchers and practitioners to extend our knowledge of gamification research.

32. Activity Theory Analysis of the Virtualisation of Teaching and Teaching Environment in a Developing Country University

Author

Adam, Ibrahim Osman, Effah, John, and Boateng, Richard

Abstract

This study aims to understand how a developing country higher education institution (HEI) attempted to digitalise teaching. The Internet has disrupted the traditional teaching environment and teaching practices leading to the migration from physical face-to-face teaching to online teaching changing the work environment of the teacher. Information systems literature has examined the academic environment of HEIs from student's perspective in a virtual learning environment but not from the instructor's perspective in a teaching work environment. How the teaching work environment can be virtualised has not also been widely explored. Using activity theory and an interpretive case study approach data was obtained from interviews, documents and participant observation. Using hermeneutics as the mode of analysis the findings reveal how tools: an open source technology and rules are modified through the resolution of contradictions to suit developing country context of the HEI. The study provides practitioners insights on how emerging contradictions in tools, implementers and rules in a teaching work environment virtualisation can be used as an avenue for development. It also offers insight into how HEIs can migrate their physical teaching environment to online.
