It has been proposed that spatial relations can be encoded in two different ways: categorically, where the relative position of objects can be described in prepositional terms (to the left/right, above/below, etc.) and coordinately, where a precise distance between the objects is assessed. Processing of categorical and coordinate spatial relations…

In the first part of this dissertation, we study the competition among network service providers in a parallel-link network with the presence of elastic user demand that diminishes both with higher prices and congestion. First we analyze a game where providers strategically price their service for single class of traffic. Later we analyze a game…

The purpose of this study was to explore human resource (HR) managers' perceptions of training practices (i.e., needs assessment, trainee preparation, training program review, accountability, management support, knowledge transfer, and performance improvement) in Saudi private sector organizations. The research questions were: (1) How do HR…

The authors believe that the adoption of virtual worlds is suitable for electronic government applications as it can increase the capillarity of public services, facilitate the access to government services and provide citizens with a natural and immersive experience. They present a Government Virtual Institution Model (GVI) for the provision of…

At the 2011 ALA conference, social media was still a topic of many discussions. For the past few years, librarians have shared their efforts to incorporate social networking applications like Facebook and Twitter as part of library services. Some librarians have taken on the challenge of establishing a social network for their library, while…

Rapid growth in eBusiness has made industry and commerce increasingly dependent on the hardware and software infrastructure that enables high-volume transaction processing across the Internet. Large transaction volumes at major industrial-firm data centers rely on robust transaction protocols and adequately provisioned hardware capacity to ensure…

In this article, centrality is explored as a measure of computer-mediated communication (CMC) in networked learning. Centrality measure is quite common in performing social network analysis (SNA) and in analysing social cohesion, strength of ties and influence in CMC, and computer-supported collaborative learning research. It argues that measuring…

The authors describe an Open Source approach to education. They define Open Source Education (OSE) as a teaching and learning framework where the use and presentation of information is non-hierarchical, malleable, and subject to the needs and contributions of students as they become "co-owners" of the course. The course transforms itself into an…

Supporting undergraduate students with their academic literacies has recently been a major focus in higher education in the UK. This paper explores the value of tutor mediation in the context of academic writing development among undergraduate business studies students in open and distance learning, following the dynamic assessment (DA) approach…

Teaching communication policy to young college students can be a challenge. Students often consider law and policy as difficult, abstract, or even unrelated to their lives. Yet experienced teachers note that students--especially those who are first exposed to regulatory concepts--benefit when they actively participate, engage, and deliberate for…

The demand for biodiversity data is increasing. Governments require standardised, objective data to underpin planning and conservation decisions. These data are produced by large numbers of (volunteer) natural historians and non-governmental organisations. This article analyses the interface between the state and the volunteer naturalists to…

Researchers are often distressed to discover that the data they wanted to use in their landmark study is not configured in a way that is usable by a Statistical Analysis Software Package (SASP). For example, the data needed may come from two or more sources and it may not be clear to the researcher how to get them combined into one analyzable…

This study, the first phase of a multi-phase effort, was undertaken to assess and provide for the information needs of the Faculty of the Schools of Science and Engineering at The College of New Jersey (TCNJ) in the digital age. The objectives of this phase were to: 1) gain an in-depth understanding of how computer science and engineering faculty…

Information Assurance (IA) is a relatively new field in the Information Technology (IT) construct. Strategies for establishing standards, training, and evaluations for IA are still developing and growing across the IT field. As new threats and vulnerabilities are identified in IA, new information, policies, and procedures must be established and…

Many types of learning require the mapping of information across situations. The proposed organizational framework extends the cognitive study of mappings across problems to include mappings across representations, solutions, and sociocultural contexts. I apply one-to-one, one-to-many, and partial mappings to analyze representative cases that…
