No matter how many car washes or bake sales schools host to raise money, adding funds to their coffers is a recurring problem. This perpetual financial difficulty makes expansive technology purchases or changes seem like a pipe dream for school CIOs and has education technologists searching for ways to stretch money. In 2005, state K-12 school…

The demand for graduates with exposure in Cloud Computing is on the rise. For many educational institutions, the challenge is to decide on how to incorporate appropriate cloud-based technologies into their curricula. In this paper, we describe our design and experiences of integrating Cloud Computing components into seven third/fourth-year…

IT leaders today must not only provide but also decide: which tools and services should they continue to supply, which are better delivered by others, and perhaps most critically, which methods from among the bewildering array of alternative sourcing strategies will best serve their faculty, staff, and students. In 2009, the EDUCAUSE Center for…

As news outlets create headlines such as "A Cloud & A Prayer," "The Cloud Is the Computer," and "Leveraging Clouds to Make You More Efficient," many readers have been left with cloud confusion. Many definitions exist for cloud computing, and a uniform definition is hard to find. In its most basic form, cloud…

In demand paging virtual memory systems, the page fault rate of a process varies with the number of memory frames allocated to the process. When an increase in the number of allocated frames leads to an increase in the number of page faults, Belady's anomaly is said to occur. In this paper, we present a probability model for Belady's anomaly. We…

Your learning curriculum needs a new technological platform, but you don't have the expertise or IT equipment to pull it off in-house. The answer is a learning system that exists online, "in the cloud," where learners can access it anywhere, anytime. For trainers, cloud-based coursework often means greater ease of instruction resulting in greater…

In this case study the authors describe Pepperdine University Libraries' migration to OCLC's WorldShare Management Services. They elaborate on the rationale for the decision, review some of the challenges and lessons encountered along the way, and briefly discuss some effects of the new system on our libraries. The focus is on technical services…

One of the most explosive areas of growth in the field of higher education is currently in emerging international markets. In developing nations, lack of access to high-quality teachers and educational materials is often the key obstacle preventing students from gaining the skills and knowledge they need to pursue new opportunities and advance in…

Collective communication allows efficient communication and synchronization among a collection of processes, unlike point-to-point communication that only involves a pair of communicating processes. Achieving high performance for both kernels and full-scale applications running on a distributed memory system requires an efficient implementation of…

In today's world, information is increasingly created, processed, transmitted, and stored digitally. While the digital nature of information has brought enormous benefits, it has also created new vulnerabilities and attacks against data. Unlike physical documents, digitally stored information can be rapidly copied, erased, or modified. The…

This article explains how the document management team (circulation and interlibrary loan) at the University of Maryland University College implemented Microsoft's SharePoint product to create a central hub for online collaboration, communication, and storage. Enhancing the team's efficiency, organization, and cooperation was the primary goal.…

As universities continually update and assess their curriculums, mainframe computing is quite often overlooked as it is often thought of as "legacy computer." Mainframe computing appears to be either uninteresting or thought of as a computer past its prime. However, both assumptions are leading to a shortage of IS professionals in the…

This paper reviews the research on the disruptive and transformative potential of newly-emerging cloud-based pedagogies. It takes into consideration the extent to which Cloud Computing can be leveraged to disseminate and scale web-based applications within and across learning contexts. It examines ideas from current literature in Web 2.0- and…

Some of the most significant changes in information technology are those that have given the individual user greater power to choose. The first of these changes was the development of the personal computer. The PC liberated the individual user from the limitations of the mainframe and minicomputers and from the rules and regulations of centralized…

This article discusses the importance of saving data safely. Suggestions include making backup copies of all important computer documents; frequently hitting the Ctrl-S keys to save current documents to the hard disk; periodically save a backup copy to a floppy disk; periodically saving a copy through the Internet to an offsite backup disk; and…
