Assessing Public Perception And Proposing An Organized Questionnaire For The Deployment And Adoption Of Autonomous Vehicles, Md Rakibul Islam

Electronic Theses and Dissertations, 2020-2023

Since the general public will play a central role in the evolution of AVs, research has been performed to assess their perception and acceptance of AVs. Nevertheless, the most potential users of AVs, i.e., young, students, and more educated people, have not received any particular focus in those studies. This research gap has motivated us to assess their perceptions. Extensive data analyses of the survey at the University of Central Florida with a sample of 315 reveal that on average 57% of the respondents were familiar with AVs, and about 44% of the respondents felt positive perceptions toward AVs. Around …

Space-Time Photonics, Abbas Shiri Jan 2022

Space-Time Photonics, Abbas Shiri

Electronic Theses and Dissertations, 2020-2023

Many of the features of photonic devices, including some of the most ubiquitous components such as resonators and waveguides, are usually thought to be intrinsically dependent on their geometry and constitutive materials. As such, the behaviour of an optical field interacting with such devices is dictated by the boundary conditions imposed upon the field. For instance, the resonant wavelengths and linewidths of a planar cavity are expected to be set by the mirrors' reflectivity, cavity length, and refractive index. Henceforth, satisfying a longitudinal phase-matching condition allows for incident light to resonate with the cavity. As another example, consider the planar …

The Impact Of Social Capital On U.S. Based Destination Marketing Organizations And Interorganizational Relationships, Jeremy Fairley Jan 2022

The Impact Of Social Capital On U.S. Based Destination Marketing Organizations And Interorganizational Relationships, Jeremy Fairley

Electronic Theses and Dissertations, 2020-2023

Previous literature echoes the notion that destination marketing organizations (DMOs) play a critical role in ensuring a desired tourism development scenario. To date, the performance measurement of destination marketing organizations is paralleled to financial indicators or operations, ignoring the presence and quality of relationships among DMOs and tourism stakeholders. Based on the premise of social capital theory, it is argued that social capital and the inter-organizational relationships between DMOs and tourism stakeholders can influence the success of tourism efforts in a destination, which in return is a contributing factor to the DMOs success as an organization. Furthermore, broader literature indicates …
