Consumer adoption of an aggregated electronic bill presentment and payment solution in South Africa using the technology acceptance model

Naidoo, Coopoosammy Velasen 25 March 2010 (has links)
This study tries to identify the key factors that influence the acceptance of an aggregated electronic bill presentment and payment solution in South Africa. As technology acceptance models are primarily developed and validated in developed countries, a new model had to be respecified to fit the South African context. Two constructs, namely perceived usefulness from the Technology Acceptance Model and a new construct “confidence”, including antecedents, were formulated from our literature review. Using a research instrument of an online survey, we measured the 81 responses received from a judgemental sample of South African internet users. The data was analysed by using linear regression analysis to test the model as well as individual hypotheses. Our respecified model was found to be highly significant providing 31, 2% explanatory power to influence adoption. The confidence construct was only marginally significant and may be an area for future research. The key themes emanating from our research indicates that consumers who value “time savings” and are “self-identified adopters” are likely to be the early adopters of EBPP. Concern for privacy and the perceived advantage to current methods of paying bills online are eminent; however, a majority (96, 3%) of the respondents indicated a willingness to adopt EBPP with 58% indicating regular levels of usage.

Practicing Democracy: Improving Participatory Technology Assessment for Sustainability Challenges

January 2019 (has links)
abstract: Participatory approaches to policy-making and research are thought to “open up” technical decision-making to broader considerations, empower diverse public audiences, and inform policies that address pluralistic public goods. Many studies of participatory efforts focus on specific features or outcomes of those efforts, such as the format of a participatory event or the opinions of participants. While valuable, such research has not resolved conceptual problems and critiques of participatory efforts regarding, for example, their reinforcement of expert perspectives or their inability to impact policy- and decision-making. I studied two participatory efforts using survey data collected from participants, interviews with policy makers and experts associated with each project, and an analysis of project notes, meeting minutes, and my own personal reflections about each project. Both projects were based one type of participatory effort called Participatory Technology Assessment (pTA). I examined how project goals, materials, and the values, past experiences, and judgments of practitioners influenced decisions that shaped two participatory efforts to better understand how practitioners approached the challenges associated with participatory efforts. I found four major themes that influenced decisions about these projects: Promoting learning; building capacity to host pTA events; fostering good deliberation; and policy relevance. Project organizers engaged in iterative discussions to negotiate how learning goals related to dominant ideas from policy and expert communities and frequently reflected on the impact of participatory efforts on participants and on broader socio-political systems. Practitioners chose to emphasize criteria for deliberation that were flexible and encompassing. They relied heavily on internal discussions about materials and format, and on feedback collected from participants, policy makers, and other stakeholders, to shape both projects, though some decisions resulted in unexpected and undesirable outcomes for participant discussions and policy relevance. Past experience played a heavy role in many decisions about participatory format and concerns about deliberative or participatory theory were only nominally present. My emphasis on understanding the practice of participatory efforts offers a way to reframe research on participatory efforts away from studying ‘moments’ of participation to studying the larger role participatory efforts play in socio-political systems. / Dissertation/Thesis / Doctoral Dissertation Sustainability 2019

Enhancing impact assessment with extrapolative fiction

Miller, Ruth-Ellen 01 January 1984 (has links)
This dissertation proposes the use of fiction as models to enhance the process of impact assessment (IA) and to improve the quality of IA reports. It demonstrates that works of extrapolative fiction (EF), a subset of science fiction, raise issues and clarify concerns not currently included in the IA process, suggesting the potential for improving the relevance of IA results for decisionmakers. The dissertation also demonstrates that EF stories can enhance the presentation of IA results, making those results more readable. Through literature review and content analysis, the current IA process is shown to lead to results lacking in specific content areas (e.g., effects on emotional well-being and community cohesiveness) necessary for their utility to decisionmakers. The body of literature here called extrapolative fiction is then shown to include many content areas missing in existing assessments. Two alternatives for an IA process that could incorporate extrapolative fiction are presented and discussed by means of examples. The first includes existing EF stories as a part of or an appendage to an IA report. The example is a preliminary combining of published EF stories with an IA report concerning life-extending technologies. The second includes the use of existing EF stories in the assessment process through inclusion of an EF-oriented reader on the IA team. The example is a case description of an IA process regarding the commercialization of guayule as a source of natural rubber, a process in which the author incorporated EF methods. Severa other results emerged from this research: (a) an initial statement of objectives for a unified field of impact assessment (recently emerging as an amalgamation of technology assessment, environmental impact statements and social impact assessment); (b) a working definition for an emerging subgenre of science fiction here called extrapolative fiction; (c) a topical bibliography of some hundred EF stories. These results extend the current understanding of the field of impact assessment and the emerging genre of extrapolative fiction and should be useful to both the impact assessment and science fiction criticism communities.

LCA and Responsible Innovation of Nanotechnology

January 2013 (has links)
abstract: Life cycle assessment (LCA) is a powerful framework for environmental decision making because the broad boundaries called for prevent shifting of burden from one life-cycle phase to another. Numerous experts and policy setting organizations call for the application of LCA to developing nanotechnologies. Early application of LCA to nanotechnology may identify environmentally problematic processes and supply chain components before large investments contribute to technology lock in, and thereby promote integration of environmental concerns into technology development and scale-up (enviro-technical integration). However, application of LCA to nanotechnology is problematic due to limitations in LCA methods (e.g., reliance on data from existing industries at scale, ambiguity regarding proper boundary selection), and because social drivers of technology development and environmental preservation are not identified in LCA. This thesis proposes two methodological advances that augment current capabilities of LCA by incorporating knowledge from technical and social domains. Specifically, this thesis advances the capacity for LCA to yield enviro-technical integration through inclusion of scenario development, thermodynamic modeling, and use-phase performance bounding to overcome the paucity of data describing emerging nanotechnologies. With regard to socio-technical integration, this thesis demonstrates that social values are implicit in LCA, and explores the extent to which these values impact LCA practice and results. There are numerous paths of entry through which social values are contained in LCA, for example functional unit selection, impact category selection, and system boundary definition - decisions which embody particular values and determine LCA results. Explicit identification of how social values are embedded in LCA promotes integration of social and environmental concerns into technology development (socio-enviro-technical integration), and may contribute to the development of socially-responsive and environmentally preferable nanotechnologies. In this way, tailoring LCA to promote socio-enviro-technical integration is a tangible and meaningful step towards responsible innovation processes. / Dissertation/Thesis / M.S. Engineering 2013

Integrating dependencies into the technology portfolio: a feed-forward case study for near-earth asteroids

Taylor, Christianna Elizabeth 15 November 2011 (has links)
Technology Portfolios are essential to the evolution of large complex systems. In an effort to harness the power of new technologies, technology portfolios are used to predict the value of integrating them into the project. This optimization of the technology portfolio creates large complex design spaces; however, many processes operate on the assumption that their technology elements have no dependency on each other, because dependencies are not well defined. This independence assumption simplifies the process, but suggests that these environments are missing out on decision power and fidelity. Therefore, this thesis proposed a way to explain the variations in Portfolio recommendations as a function of adding dependencies. Dependencies were defined in accordance with their development effort figures of merit and possible relationships. The thesis then went on to design a method to integrate two dependency classes into the technology portfolio framework to showcase the effect of incorporating dependencies. Results indicated that Constraint Dependencies reduced the portfolio or stayed the same, while Value Dependencies changed the portfolio optimization completely; making the user compare two different optimization results. Both indicated that they provided higher fidelity with the inclusion of the information added. Furthermore, the upcoming NASA Near-Earth Asteroid Campaign was studied as a case study. This campaign is the plan to send humans to an asteroid by 2025 announced by President Obama in April 2010. The campaign involves multiple missions, capabilities, and technologies that must be demonstrated to enable deep-space human exploration. Therefore, this thesis capitalized on that intention to show how adopting technology in earlier missions can act as a feed-forward method to demonstrate technology for future missions. The thesis showed the baseline technology portfolio, integrated dependencies into the process, compared its findings to the baseline case, and ultimately showed how adding higher fidelity into the process changes the user's decisions. Findings concerning the Near-Earth Asteroid Campaign, the use of dependencies to add fidelity and implications for future work are discussed.
