Informational Power On Twitter: A Mixed-Methods Exploration Of User Knowledge And Technological Discourse About Information Flows, Nicholas John Proferes May 2015

Informational Power On Twitter: A Mixed-Methods Exploration Of User Knowledge And Technological Discourse About Information Flows, Nicholas John Proferes

Theses and Dissertations

Following a number of recent examples where social media users have been confronted by information flows that did not match their understandings of the platforms, there is a pressing need to examine public knowledge of information flows on these systems, to map how this knowledge lines up against the extant flows of these systems, and to explore the factors that contribute to the construction of knowledge about these systems. There is an immediacy to this issue because as social media sites become further entrenched as dominant vehicles for communication, knowledge about these technologies will play an ever increasing role in …

Password Strength Analysis: User Coping Mechanisms In Password Selection, Brian Thomas Curnett Apr 2015

Password Strength Analysis: User Coping Mechanisms In Password Selection, Brian Thomas Curnett

Open Access Theses

The security that passwords provide could be seriously flawed due to the way people cope with having to memorize and recall their passwords. The National Institute of Standards and Technology (NIST) standard that is used to measure the password strength, known as entropy, is designed for a single use and does not consider that users may choose to keep parts of their password across password changes. This study shows that a portion of users keep some information from previous passwords across changes. These habits which will be called coping mechanisms that over time serve to erode the protection provided by …

A Prediction Modeling Framework For Noisy Welding Quality Data, Junheung Park Jan 2015

A Prediction Modeling Framework For Noisy Welding Quality Data, Junheung Park

Wayne State University Dissertations

Numerous and various research projects have been conducted to utilize historical manufacturing process data in product design. These manufacturing process data often contain data inconsistencies, and it causes challenges in extracting useful information from the data. In resistance spot welding (RSW), data inconsistency is a well-known issue. In general, such inconsistent data are treated as noise data and removed from the original dataset before conducting analyses or constructing prediction models. This may not be desirable for every design and manufacturing applications since every data can contain important information to further explain the process. In this research, we propose a prediction …

Assessing Clinical Software User Needs For Improved Clinical Decision Support Tools, Kimberly B. Denney Jan 2015

Assessing Clinical Software User Needs For Improved Clinical Decision Support Tools, Kimberly B. Denney

Walden Dissertations and Doctoral Studies

Consolidating patient and clinical data to support better-informed clinical decisions remains a primary function of electronic health records (EHRs). In the United States, nearly 6 million patients receive care from an accountable care organization (ACO). Knowledge of clinical decision support (CDS) tool design for use by physicians participating in ACOs remains limited. The purpose of this quantitative study was to examine whether a significant correlation exists between characteristics of alert content and alert timing (the independent variables) and physician perceptions of improved ACO quality measure adherence during electronic ordering (the dependent variable). Sociotechnical theory supported the theoretical framework for this …

Evaluating Success Factors In Implementing E-Maintenance In Maintenance, Repair, And Overhaul (Mro) Organizations, Peter Rocky Toves Jan 2015

Evaluating Success Factors In Implementing E-Maintenance In Maintenance, Repair, And Overhaul (Mro) Organizations, Peter Rocky Toves

Walden Dissertations and Doctoral Studies

Despite more than a decade-long process to transition aircraft maintenance practices from paper-to electronic-based systems, some organizations remain unable to complete this transition. Researchers have indicated that while organizations have invested resources in technology improvements, there remains a limited understanding of the factors that contribute to effectively managing technology-enabled change. The purpose of this case study was to identify and explore socio-technical (ST) factors that inhibit an effective transition from a paper-based system to an electronic-based system for aircraft maintenance. A conceptual model applying theories of change management, technology acceptance, systems thinking, and ST theory informed the research. Thirteen participants …

Three Essays On Global Ict Phenomenon: Productivity Paradox, Organizational Ict Use, And Privacy In Social Networks, Faruk Arslan Jan 2015

Three Essays On Global Ict Phenomenon: Productivity Paradox, Organizational Ict Use, And Privacy In Social Networks, Faruk Arslan

Open Access Theses & Dissertations

This Dissertation aims to investigate the global diversity in information systems by studying three distinctive phenomena. The first essay investigates the existence of "IT Productivity Paradox" within firms operating in developing countries using an empirical approach. IT Productivity Paradox has been a widely investigated topic within the context of developed countries and primarily studied within the context of developing countries using a single country. Our research addresses a gap in the literature, which is the study of IT Productivity Paradox across several developing countries with diverse characteristics. The second essay studies the contextual factors (firm characteristics and perception of external …
