Individuals may encounter many negativities due to the misuse of computers and the Internet. Children suffer the most from these negativities. This situation necessitates parents who always protect and stand by their children, to become knowledgeable about the safe use of computers and the Internet. In this study, we examined the opinions of the…

Faculty in the information systems (IS) and information technology (IT) fields are faced with the challenge to keep their curriculum relevant and current. What was taught two years ago will often be outdated and faculty must constantly update their curriculum on which courses should be taught as well as what should be taught within a particular…

In the fields of information technology and information systems, faculty must consistently adjust the curriculum to meet the demands of the field. However, a challenge they often face is understanding what should be covered, especially given the limited number of courses most universities are able to offer. This research is a biennial report of…

Trust management in mobile networks is challenging due to dynamically changing network environments and the lack of a centralized trusted authority. In this dissertation research, we "design" and "validate" a class of dynamic trust management protocols for mobile networks, and demonstrate the utility of dynamic trust management…

Remote working is the new reality, and transactional work--provided by freelancers, contract employees or consultants--has increased exponentially. It is forecast that as much as half the labor force will be working independently and virtually by 2020. Most organizations are still grappling with how to effectively manage their virtual staff and…

Cryptography libraries are inflexible and difficult for developers to integrate with their applications. These difficulties are often encountered by applications, like PGP, which are non-intuitive for end-users and are often used improperly or not at all. This thesis discusses the negative impact of the current prevailing poor usability on…

Cybercriminals are increasingly using Internet-based text messaging applications to exploit their victims. Incidents of deceptive cybercrime in text-based communication are increasing and include fraud, scams, as well as favorable and unfavorable fake reviews. In this work, we use a text-based deception detection approach to train models for…

Wireless Sensor Networks (WSNs) have unique characteristics which constrain them; including small energy stores, limited computation, and short range communication capability. Most traditional security algorithms use cryptographic primitives such as Public-key cryptography and are not optimized for energy usage. Employing these algorithms for the…

The recent White House (2011) policy paper for the Smart Grid that was released on June 13, 2011, "A Policy Framework for the 21st Century Grid: Enabling Our Secure Energy Future," defines four major problems to be solved and the one that is addressed in this dissertation is Securing the Grid. Securing the Grid is referred to as one of…

The aim of this paper is to illuminate the exciting world in which "white hat crackers" operate and to suggest topics that can help prepare students to enter this high-demand field. While currently there is extraordinary demand for graduates to fill these positions that have relatively high starting salaries, employers find it difficult…

This study examines the web design and engineering, advertising and marketing, and pedagogical features present at a random sample of 71 international poker sites obtained from the Casino City directory in the summer of 2009. We coded for 22 variables related to access, appeal, player protection, customer services, on-site security, use of images,…

Learning management systems (LMSs) have dominated the teaching and learning landscape in higher education for the past decade, with a recent Delta Initiative report indicating that more than 90 percent of colleges and universities have a standardized, institutional LMS implementation. While the LMS has become central to the business of colleges…

With the success of applications spurring the tremendous increase in the volume of data transfer, efficient and reliable content distribution has become a key issue. Peer-to-peer (P2P) technology has gained popularity as a promising approach to large-scale content distribution due to its benefits including self-organizing, load-balancing, and…

Today, advances in wireless sensor networks are making it possible to capture large amounts of information about a person and their interaction within their home environment. However, what is missing is how to ensure the security of the collected data and its use to alter human behavior for positive benefit. In this research, exploration was…

This paper presents the structure of an undergraduate course entitled "programming techniques and the use of specialised software in structural engineering" which is offered to the fifth (final) year students of the Civil Engineering Department of Aristotle University Thessaloniki in Greece. The aim of this course is to demonstrate the…
