Cyber-security involves the monitoring a complex network of inter-related computers to prevent, identify and remediate from undesired actions. This work is performed in organizations by human analysts. These analysts monitor cyber-security sensors to develop and maintain situation awareness (SA) of both normal and abnormal activities that occur on…

Cloud computing offers the advantage of on-demand, reliable and cost efficient computing solutions without the capital investment and management resources to build and maintain in-house data centers and network infrastructures. Scalability of cloud solutions enable consumers to upgrade or downsize their services as needed. In a cloud environment,…

In 2011 alone, over 56,000 refugees were admitted to the United States and a third of these individuals were under the age of 18 (Martin & Yankay, 2012). Researchers have found that the social capital developed through close and confiding relationships is instrumental in the academic outcomes of refugee youth (Kia-Keating & Ellis, 2007;…

Today's modern mobile devices (such as smartphones and tablets) present great potential for growth of many novel, powerful, but also highly demanding applications. However, most mobile devices/users operate in isolation from one another, i.e., they are not aware of the presence of other devices in their proximity. There are numerous situations…

This doctoral dissertation is focused on both empirical and conceptual contributions relative to the roles social technologies play in informal knowledge sharing practices, both within and across organizations. Social technologies include (a) traditional social technologies (e.g., email, phone and instant messengers), (b) emerging social…

Location technologies constitute an essential component of systems design for autonomous operations and control. The Global Positioning System (GPS) works well in outdoor areas, but the satellite signals are not strong enough to penetrate inside most indoor environments. As a result, a new strain of indoor positioning technologies that make use of…

This dissertation uses design science research and engineering to develop a cloud-based simulator for modeling next-generation cybersecurity protection frameworks in the United States. The claim is made that an agile and neutral framework extending throughout the cyber-threat plane is needed for critical infrastructure protection (CIP). This…

Inside campus libraries and dormitory rooms, thousands of students connect to the Internet not only to study with online systems like Blackboard but also to watch movies and TV shows on Netflix. Computers, smartphones, wireless printers, tablets, iPods, Xboxes, handheld gaming systems, e-readers, smart TVs, Blu-ray players--students now bring an…

This is an exploratory study investigating the use of social networking tools in academic libraries, examining the extent of their use, library staff's perceptions of their usefulness and challenges, and factors influencing decisions to use or not to use such tools. Invitations to participate in a web-based survey were sent to 140 university…

Cross-border academic collaborations in conflict zones are vulnerable to escalated turbulence, liability concerns and flagging support. Multi-level stakeholder engagement at home and abroad is essential for securing the political and financial sustainability of such collaborations. This study examines the multilayered stakeholder arrangements…

Rural clergy often lack colleagues and may struggle with isolation, especially if over-extended in multi-parish benefices. Theory suggests that this sense of isolation could be addressed by launching clergy action learning sets, which have the potential to establish a peer support network through the formation of social capital as a by-product of…

Despite the perception that face-to-face classrooms provide speaking opportunities, studies by Fassinger (1995), Nunn (1996), and Weimer (2013) have conveyed that there is limited interaction in a traditional college lecture setting. Social media networks such as Twitter provide an opportunity for instructors to utilize popular mobile technology…

Purpose: This paper aims to test the need in the Australian higher education (HE) sector for a national network for the peer review of assessment in response to the proposed HE standards framework and propose a sector-wide framework for calibrating and assuring achievement standards, both within and across disciplines, through the establishment of…

With the excessive use of social media in the 21st century, attempts to integrate social media within higher education have also increased. In this area, research has been particularly focused on the aspects of students, rather than the instructors. This study puts the emphasis on the instructors with the aim to explore their use of social media…

The authors in this study seek to inform academia about international students' experiences and challenges while attending universities in Small Town USA. Despite their eagerness to study in the United States (U.S.), international students are faced with setbacks that many universities fail to recognize or realize. The researchers conducted…
