SVM-based texture classification in optical coherence tomography

This paper describes a new method for automated texture classification for glaucoma detection using high resolution retinal Optical Coherence Tomography (OCT). OCT is a non-invasive technique that produces cross-sectional imagery of ocular tissue. Here, we exploit information from OCT im-ages, specifically the inner retinal layer thickness and speckle patterns, to detect glaucoma. The proposed method relies on support vector machines (SVM), while principal component analysis (PCA) is also employed to improve classification performance. Results show that texture features can improve classification accuracy over what is achieved using only layer thickness as existing methods currently do.

The Impact of Security and Privacy Concerns on Home Internet Use by Parents and Children

Internet users’ choices about their extent and types of usage and the types of precautions they take for their online security and privacy is an increasingly important research topic. As business and personal Internet usage grows so do concerns about misuse and abuse leading to financial loss or breaches of privacy. For the younger user, the risk of sexual exploitation from misuse is a particular concern. Effective mitigation of these risks is critical to the full achievement of the benefits the Internet can offer in e-commerce, e-learning, business and social communication. The interrelations between comfort with sensitive Internet use, security measures taken, and the types of Internet usage among home Internet users has not been extensively examined. We plan to empirically examine these interactions and to then extend our analysis to examine the impact of parental attitudes, usage, and controls on Internet usage

The digital divide and K-12 student computer use

The divide between those who have computer and Internet access and those who do not appears to be narrowing, however overall statistics may be misleading. Measures of computer availability in schools often include cases where computers are only available for administration or are available only on a very limited basis (Gootman, 2004). Access to a computer and the Internet outside of school helps to reinforce student learning and emphasize the importance of using technology. Recent U.S. statistics indicate that ethnic background and other demographic characteristics still have substantial impact on the availability and use of computers by students outside of the classroom. This paper examines recent census data to determine the impact of the household on student computer use outside of the classroom. Encouragingly, the findings of this study suggest that use of a computer at school substantially increases the chance that a student will use a computer outside of class. Additionally, this study suggests that computer use outside of the classroom is positively and significantly impacted by being in a household with adults who either use a computer at work or work in an industry where computers are extensively used

Development implementation, and assessment of course learning outcomes: Working paper series--02-01

This paper describes a process for developing program learning outcomes for an undergraduate business major program and mapping more specific course-level learning outcomes to these program-level outcomes. Also described is a process for assessing the effectiveness with which the course-level learning outcomes have been achieved. The processes is designed to provide a mechanism for making broad program level outcomes meaningful to instructors in their ongoing delivery of the program

A Survey of MIS Emphases in MBA Degree Programs

An exploratory survey of 111 colleges and universities that offer an MIS specialization in the MBA program was conducted. Survey data was compared to data obtained on nonrespondents to test for sample bias. No significant differences were found between respondent and nonrespondent schools. The data was then combined and reported. Most MBA-MIS specialization programs require little prior computer experience. Most of the entering students have professional experience and about one-quarter have IS related experience. A majority of programs emphasize IS analyst skills. Systems analysis and design and database management systems were the most prevalent of course offerings. Employer and student demand for these programs appear to be increasing
