iv This dissertation is about audio content-based search. Specifically, it is on developing tech-nologies for bridging the semantic gap that currently prevents wide-deployment of audio content-based search engines. Audio search engines rely on metadata, mostly human gener-ated, to manage collections of audio assets. Even though time-consuming and error-prone, human labeling is a common practice. Audio content-based methods, algorithms that auto-matically extract description from audio files, are generally not mature enough to provide a user friendly representation for interacting with audio content. Mostly, content-based methods are based on low-level descriptions, while high-level or semantic descriptions are beyond current capabilities. This dissertation has two parts. In the first one we explore the strengths and limitation of a pure low-level audio description technique: audio finger-printing. We prove, by implementation of different systems, that automatically extracted low-level description of audio are able to successfully solve a series of tasks such as linking unlabeled audio to corresponding metadata, duplicate detection or integrity verification.

This article describes the third phase of a study which examined the readiness of technology education and career and technical education fields for online and hybrid doctoral degree programs in technical education. In this phase, interviews were conducted with chairs and coordinators of 19

The SPLASH-2 suite of parallel applications has recently been released to facilitate the study of centralized and distributed shared-address-space multiprocessors. In this context, this paper has two goals. One is to quantitatively characterize the SPLASH-2 programs in terms of fundamental

This paper discusses the feeling of isolation among doctoral students; its ’ origin and the effect it has on the decision of the students to leave doctoral programs. The paper explains the development of isolation feeling within four stages of completing the program. It explains how each stage

During the past 20 years there has been a dramatic increase in societal interest in preventing disability and death in the United States by changing individual behaviors linked to the risk of contracting chronic diseases. This renewed interest in health pro-motion and disease prevention has not been without its critics. Some critics have accused proponents of life-style interventions of promoting a victim-blaming ideology by neglecting the importance of social influences on health and disease. This article proposes an ecological model for health promotion which focuses atten-tion on both individual and social environmental factors as targets for health promo-tion interventions. It addresses the importance of interventions directed at changing interpersonal, organizational, community, and public policy, factors which support and maintain unhealthy behaviors. The model assumes that appropriate changes in the social environment will produce changes in individuals, and that the support of individ-uals in the population is essential for implementing environmental changes.
