Three members of my family have been diagnosed with cancer in the past five years. During the fall of my freshman year of high school, my older brother was diagnosed with acute lymphocytic leukemia. His health began to deteriorate in August 2006. My mother would take him to the hospital weekly, insisting that the doctors run every test on her ill-ridden son. Chris's diagnosis in November 2006 a...

Extracting entities from natural language text to design conceptual models of the entity relationships is not trivial and novice designers students can find it especially difficult. Researchers have suggested linguistic rules/guidelines for extracting text. Unfortunately, while these guidelines are often correct they can, also, be invalid. There no rule that true at all times. This paper sugges...

This paper reflects on the experiences of facilitating and maintaining qualitative research access into a sample of international hotel groups. The existing research methodology literature tends to simplify the access process by explaining it through a number of stages. The fieldwork experience of the authors suggests that the propositions stated in literature are partly relevant; however, ther...

Context awareness is increasingly gaining applicability in interactive ubiquitous mobile computing systems. Each context-aware application has its own set of behaviors to react to context modifications. This paper is concerned with the context modeling and the development methodology for context-aware systems. We proposed a rule-based approach and use the adaption tree to model the adaption rul...

Large databases are routinely being collected in government, science, business and medicine. A variety of techniques from statistics, signal processing, pattern recognition, machine learning, and neural networks have been proposed to help people understand the data by discovering predictive models of the data. However, research in data mining has not paid attention to the factors that make lear...
