Digital Image Access & Retrieval

The 33th Annual Clinic on Library Applications of Data Processing, held at the University of Illinois at Urbana-Champaign in March of 1996, addressed the theme of "Digital Image Access & Retrieval." The papers from this conference cover a wide range of topics concerning digital imaging technology for visual resource collections. Papers covered three general areas: (1) systems, planning, and implementation; (2) automatic and semi-automatic indexing; and (3) preservation with the bulk of the conference focusing on indexing and retrieval.published or submitted for publicatio

Steganoscription : exploring techniques for privacy-preserving crowdsourced transcription of handwritten documents

textThe focus my research is the historical document format represented by the Central State Hospital (CSH) dataset, handwritten medical records. The specific problem innate to the CSH dataset in question is how to transcribe sensitive, cursive-handwritten documents via a manual vehicle- such as crowdsourcing. Manual methods are necessarily no matter the sophistication of the optical character recognition system used because of the inconsistencies within cursive script. To address this problem I've developed an application that enables users to transcribe sensitive, handwritten, document images while preserving the privacy of the context around the transcribed text via random word selection and visual manipulation of the displayed text. This is made possible through several algorithms that process documents from a top-down approach. These system operations detect and segment lines of text in images, reverse the slant common to cursive script, detect and segment words, and finally, manipulate word-images before they are displayed to users; combinations of color, noise, and geometric manipulations are currently supported and used randomly. This system, called Steganoscription, combines the concepts of steganography and transcription.Informatio

Learning and technological capability building in emerging economies: the case of the biomass power equipment industry in Malaysia

There is increasing recognition that the transfer of foreign technology to developing countries should be considered in light of broader processes of learning, technological capability, formation and industrial development. Previous studies that have looked at this in the context of cleantech industries in emerging economies tend to overlook firm-level specifics. This paper contributes to filling this gap by utilising in-depth qualitative firm-level data to analyse the extent to which the use of different learning mechanisms can explain differences in the accumulation of technological capabilities. This is explored via an examination of eight firms in the biomass power equipment industry in Malaysia during the period 1970-2011. The paper finds that firms relying on a combination of learning from foreign technology partners and internal learning by planned experimentation make most progress in terms of technological capability. Nevertheless, local spill-over effects were found to be important for some firms who learned principally from imitation of local competitors, although significantly, firms learning from local spillovers failed to advance beyond extra basic operating technological capabilities. Those firms who proactively pursued learning from foreign partners, on the other hand, advanced further, reaching basic innovative levels of technological capabilities. These findings are relevant for a wider range of industrial sectors in emerging economies

Exploring Succession Planning for Executive Leadership Positions within Ohio\u27s Faith-based Organizations: A Multiple-Case Study

The predicted shortage in the number of qualified professionals available to fill vacant executive leadership positions is a significant concern for the non-profit sector. This qualitative multiple-case study explored the general problem of the potential lack of succession planning, resulting in the inability to identify future leaders within Ohio’s faith-based organizations. Specifically, this study concentrated on the selection process of candidates for executive leadership positions, and the succession planning process that contributed to a successful or failure to implement. In a purposeful sample, eighteen (18) senior leaders located in the eastern and western regions of Ohio, were selected for this study. As part of the conceptual framework, Hershey and Blanchard’s (1993) situational leadership theory were used to understand the group facilitator’s leadership style during succession planning activities. Data was collected and analyzed from semi-structured interviews, documents, and archival records. Findings are discussed from the perspective of senior leaders, which included current and former volunteers, and employees that previously participated in succession planning activities to appoint a new leader at Ohio’s faith-based organizations. Five themes emerged from the study and highlighted the strategies chosen by senior leaders as they prepared for succession planning activities. Furthermore, the results of this study and the future recommendations provided, contributed to the body of knowledge, and expanded the topic of succession planning for executive leadership positions in the non-profit sector

Nonfiction, Documentary and Family Narrative: An Intersection of Representational Discourses and Creative Practices

Nonfiction, Documentary, and Family Narrative: An Intersection of Representational Discourses and Creative Practices explores the role of personal memory, family history, and inter-generational storytelling as the basis for making a nonfiction film. The film, American Boy, tells the story of my mother’s immigration to the United States after the failed Hungarian Revolution of 1956, opening a discussion of four generations of my family life in the context of historical events, exile, self re-invention, and identity formation. As a media producer and nonfiction author, I narrate my understanding of these events to my infant son, as a way of communicating my grandfather’s role in the revolution, my mother’s childhood, and my own mediation of my family’s trauma. Through the use of archival footage including newsreels and commercials, as well as my own archive of family photos and documents, I re-construct the existing materials to build my own associations concerning time, memory, and place. The film, as my creative practice, leads to a theoretical analysis of representational discourses which inform the work. This deconstruction of nonfiction and meta-analysis includes my study of several practitioners in the craft of non-fiction: Kati Marton, Robert Root, Primo Levi, Eva Hoffman, Patricia Hampl, Dinty W. Moore, Peter Balakian and others

Finding Family Facts in the Digital Age: Family History Research and Production Literacies

This study examines the online information behaviors of experienced and novice family history researchers, though the lens of accuracy and an increasingly digital research and production environment. It presents a model of the information behaviors of family history researchers, as well as a literacies framework, which visualizes the skills and knowledge needed to conduct accurate family history research and produce accurate family histories in the digital age.Ph.D., Information Studies -- Drexel University, 201
