Children's Color Association for Digital Image Retrieval.

Description: In the field of information sciences, attention has been focused on developing mature information retrieval systems that abstract information automatically from the contents of information resources, such as books, images and films. As a subset of information retrieval research, content-based image retrieval systems automatically abstract elementary information from images in terms of colors, shapes, and texture. Color is the most commonly used in similarity measurement for content-based image … more

Knowledge synthesis in the biomedical literature: Nordihydroguaiaretic acid and breast cancer.

Description: This dissertation refines knowledge synthesis from publicly accessible databases, based on the model of D.R. Swanson. Knowledge synthesis endeavors bring together two or more non-interactive literatures to create combinatorial research data on a specific topic. In this endeavor the biomedical literature was searched on the anti-neoplastic agent nordihydroguaiaretic acid (NDGA) for its potential role as a functional food in the chemoprevention of breast cancer. Bibliometric cocitation was utiliz… more

Measuring the accuracy of four attributes of sound for conveying changes in a large data set.

Description: Human auditory perception is suited to receiving and interpreting information from the environment but this knowledge has not been used extensively in designing computer-based information exploration tools. It is not known which aspects of sound are useful for accurately conveying information in an auditory display. An auditory display was created using PD, a graphical programming language used primarily to manipulate digital sound. The interface for the auditory display was a blank window. Whe… more

Testing a model of the relationships among organizational performance, IT-business alignment and IT governance.

Description: Information Technology (IT) is often viewed as a resource that is capable of enhancing organizational performance. However, it is difficult for organizations to measure the actual contribution of IT investments. Despite an abundance of literature, there is an insufficiency of generally applicable frameworks and instruments to help organizations definitively assess the relationship among organizational performance, IT-business alignment, and IT governance. Previous studies have emphasized IT-bus… more
