    Managing Technical Content: Investigating the Value and Impact of a Content Management System (CMS)
    (2021) De la Victoria, Miranda
    As the field of technical communication evolves and expands into various industries, the content and how it is created and managed evolves, too. The maintenance of content, specifically technical content in this case, is where content management systems (CMS) come into play. Companies often decide what kind of CMS they want to implement based on their needs. Adobe Experience Manager (AEM) is the CMS implemented by a global company. In this report, I analyzed some of the existing literature on CMS implementation and then interviewed four practitioners at the global company, who have some experience in the technical content industry, though not all identify as a technical communicator, and have been exposed to a content management system. My analysis shows that there are many reasons to implement a CMS, including reuse, translation, version control, and automation of document publishing, to name a few. Technical communicators are often introduced to CMS through their own research for content solutions or by another who is conducting that research. Through communication, collaboration, and involvement, others may be convinced of a CMS’s value. While there are many challenges with implementation, it is a matter of how they are handled that will determine whether or not an implementation is successful.

    Using Binaural Beat Sensitivity To Describe Mechanisms That May Enhance Binaural Interactions In Single-Sided-Deafness Cochlear-Implant Patients
    (2020-04) Dirks, Coral
    Patients with single-sided deafness (SSD) have difficulty localizing sound and understanding speech in noisy backgrounds. Currently, if treated at all, SSD patients may be fitted with devices that route sounds from the deaf side to the better ear. These devices have two primary limitations: (1) they decrease the signal-to-noise ratio when target signals originate on the side with the normal-hearing ear, and (2) they do not restore spatial hearing (e.g., Kitterick, Smith, & Lucas, 2016). Recently, some SSD patients have received a cochlear implant (CI) in their deaf ear (SSD+CI). The aim of this thesis was to investigate the outcomes from the intervention, to determine the mechanisms underlying any observed improvements, and to test a novel CI fitting method designed to optimize the interactions between the normal-hearing ear and the CI. Data from the first study indicated that localization and speech understanding may improve after implantation, but the improvements are generally small and are primarily mediated by head-shadow effects. The lack of greater benefits of spatial hearing and spatial release from masking in speech experiments may be due in part to the poor match of spectral location between the two ears. Current fitting strategies attempt to maximize speech perception in the implant alone. However, SSD+CI patients may benefit more from a CI fitting approach that best complements information from the normal-hearing ear by providing a closer match in terms of the tonotopic maps in both ears. The second study explored ways to assess between-ear tonotopic matches using binaural interactions produced by dynamic interaural time differences in the temporal envelope. The final study tested the newly derived maps in terms of their success in improving sound localization and speech in noise perception. Outcomes suggest that frequency-to-place matching alone does not restore binaural integration of the NH and CI ears. Future work should determine whether correcting other mismatches in the time and amplitude-mapping domains, in combination with frequency-to-place matching, will improve speech perception and spatial hearing outcomes.
