Usability has long been considered an important component of an innovation (Norman, 2002), evidenced by the fact that usability research has dominated innovation design efforts for a number of years. However, recent research has shown that satisfying usability is not sufficient for the successful diffusion and adoption of an innovation (Karsh, 2004). To develop an useful innovation, one must understand the mechanisms by which people choose to adopt and use an innovation, as well as how an innovation fits different levels of a socialtechnical system (Karsh, Escoto, Beasley, & Holden,(2006). The goal of this research, therefore, was to develop an innovation analytic and design framework that would enable designers to design a more likely adopted innovation and to validate it through the design and evaluation of a fall-protection training intervention for residential roofing subcontractors. The proposed innovation analytic and design framework was based on the traditional systems-engineering process: Requirement Analysis, Prototype Development, and Summative Evaluation. Rogers’ Theory of Innovation Diffusion and Adoption, as well as Participatory Design, were utilized to obtain a holistic view of technology-adoption challenges and opportunities. The requirement analysis involved the development and use of a questionnaire and semi-structured interviews to identify the contributors of safety technology adoption in small roofing companies, as well as to understand the practices of safety technology adoption and fall-protection training. One hundred and four questionnaires from workers in North Carolina and Virginia were collected, and 29 workers received the follow-up semi-structured interview. Results showed that (1) social influence had a significant impact on the diffusion and adoption of safety technology; (2) workers’ satisfaction with existing safety performance standards/practices, as well as disengagement during available safety training, caused difficulties in implementing regular safety training; (3) management commitment and presentation of good/bad consequences of unsafe behavior were expected to facilitate the rate of adoption of safety technology. Results also identified specific recommendations for a fall-protection training intervention. The prototype development was performed by a six-member Participatory Design (PD) team in a PD workshop, who used the results of the questionnaire and semi-structured interviews to develop a training intervention. Four PD approaches (PICTIVE, Inspiration Card Workshop, Scenario Building, and Future Workshop) were employed in the development of a Personal Fall Arrest System (PFAS) as an industry-specific training intervention. This research also used summative comparative evaluation to assess the developed PFAS training intervention against a standard PFAS training intervention with respect to (1) adoption propensity, (2) expected adoption outcome, and (3) results demonstrability. Eighteen roofing workers were recruited to evaluate and compare the two interventions. The standard PFAS training intervention was developed by two experts using the safety manual published by the National Roofing Contractor Association. Results suggested that (1) the developed PFAS training intervention was more likely to be adopted and easier to diffuse among roofing subcontractors than the standard PFAS training intervention, and (2) use of the developed PFAS training intervention would better improve company's safety performance in comparison to the standard training intervention. Results of the evaluations confirmed the efficacy of the proposed innovation analytic and design framework in designing a more likely adopted innovation. / Ph. D.

As low-voter-turnout continues to be a concern for the political system in the U.S., the idea online voting platforms (OVPs), to reduce access and use barriers, has been debated. Lowlevel elections in several states across the country have experimented with OVPs through U.S.based internet voting organization, Everyone Counts. These experiments resulted in both the confirmation of perceived benefits and problems. Surveying 196 U.S. citizens through Survey Sampling International, this study garnered respondents' feelings toward several factors correlated with voter-turnout, and the likelihood of adopting OVPs. Using the Unified Theory of Acceptance and Technology Use Model to frame the analysis, the data were analyzed using ols regression. I predicted that citizens would perceive OVPs as an improvement to the current system, and consequently, voter-turnout would increase if OVPs were available, especially among younger citizens (ages 18-44). The analyses illustrated that OVPs would not have a large impact on voter-turnout, and for some would even discourage participation. Furthermore, it was older respondents (ages 44+) who had a stronger positive correlation between effort expectancy and feeling empowered. I conclude by suggesting that low-voter-turnout might be best combated through efforts to improve political efficacy, and that accessibility to poll booths only accounts some of the story. / Master of Science

This thesis analyzes factors affecting adoption of integrated pest management (IPM) techniques by Kenyan vegetable farmers, including the role of their risk preferences. It also analyzes factors affecting their pesticide applications and expenditures. A survey was administered to 450 Kenyan vegetable growers to identify their pest management practices, and a behavioral experiment was run to elicit their risk preferences utilizing. Cumulative Prospect Theory. Loss aversion was found to be correlated with higher likelihood of IPM adoption while risk aversion was associated with higher pesticide application rates and expenditures. The influence of IPM adoption on pesticide use differed by IPM technique. / Master of Science / Integrated Pest Management (IPM) techniques can improve small holder farmers' livelihoods by lowering production costs and decreasing dependence on chemical pesticides. Even though some IPM techniques have been available to Kenyan vegetable farmers since the 1990's, IPM adoption remains relatively low while chemical pesticide use remains high. A farm-household survey and behavioral experiment were conducted to identify factors that influence farmer decisions to adopt IPM and to apply pesticides. Factors that influence IPM adoption were found to differ from those that influence pesticide decisions. Furthermore, IPM adoption by Kenyan farmers does not decrease use of chemical pesticides for all IPM techniques.

The research conducted under this study offers an understanding of the reasons why information technology (IT) and/or information assurance (IA) managers choose to recommend or not to recommend particular technologies, specifically biometric security, to their organizations. A review of the relevant literature provided the foundation to develop a set of research questions and factors for this research effort. The research questions became the basis of the study’s stated hypotheses for examining managers’ perceptions of the security effectiveness, need, reliability, and cost-effectiveness of biometrics. The research indicates that positive perceptions of security effectiveness, need, reliability, and cost-effectiveness correlate with IT/IA managers’ willingness to recommend biometric security technologies. The implications of this study are that executives and managers can make informed decisions about the recommendation and adoption process relevant to biometric security technologies through an understanding of how perceptions of biometric technology affect the decision to recommend this type of technology. The study’s results may also help biometric product developers, vendors, and marketers understand the important perceptions of biometric security technologies within their customer base of IT/IA managers.

Yes / From a perspective of the resource-based view, this paper analyses the inter-connection between technology adoption and creation in affiliates of multinational enterprises (MNEs) in an emerging economy. Operating below the international technological frontier, multinational affiliates are more motivated to adopt technologies already existent from their MNEs than create new technologies, as the former already gives them competitive advantages over local firms. When technology creation is required, multinational affiliates will adopt further technology-based resources from their MNEs as they are unavailable in an emerging economy. As a result, technology adoption is a necessary but not sufficient condition for multinational affiliates to conduct technology creation. Given that networks are particularly important for working around institutional voids in the context of an emerging economy, this paper also investigates the different roles of R&D support from internal and external networks of multinational affiliates in technology adoption and creation. Hypotheses are tested and partially supported based on unique data from 465 multinational affiliates in China.
