Building the Western Cape farmers resilience to climate change: assessing the usefulness of credibility salience and legitimacy framework in linking climate change adaptation infor... by Siziba, Bridget

“…In the context of communicating climate change adaptation information, this study examined the usefulness of the Credibility, Salience, and Legitimacy (CSL) framework, otherwise known as the knowledge system framework (Cash et al., 2003), in bridging the disconnect between information production and its use in decision-making by commercial farmers in South Africa's Western Cape Province. …”

Comparative Delivery of 1,8-Cineole and Eucalyptus Oil Using Chitosan Nanoparticles and PVA Nanofibers: A Polymeric Nanotechnology Toolbox for Antibacterial, Wound-Healing, and Ant... by Shetta, Amro AbdelAzeem

“…To address this gap, this thesis investigates a two-level comparative design, (i) a single defined molecule, 1,8-cineole (CIN), versus a compositionally diverse eucalyptus oil (EU), and (ii) one-barrier delivery (direct loading into a polymer matrix) versus a two-barrier architecture (NP-in-NF dual encapsulation) intended to strengthen retention and control diffusion at the biological interface. Chitosan nanoparticles (CS NPs) directly loaded electrospun poly(vinyl alcohol) nanofibers (PVA NFs), and NP-in-NF composite nanofibers (PVA–CS NFs containing bioactive-loaded CS NPs) were formulated and optimized using Box–Behnken designs at both the nanoparticle and electrospinning levels. …”

Utilization of personal health informatics through intermediary users by Katule, Ntwa

“…As a result, such systems may not scale well in contexts where a targeted consumer (beneficiary) may use technology through the facilitation of another person (intermediary) whom is responsible for manipulating user interfaces, because such facilitators are not recognized as part of the system, hence motivational strategies don't cater for them. …”

Towards improved visual stimulus discrimination in an SSVEP BCI by Hodgskiss, Dean Leslie

“…The dissertation investigated the influence of stimulus characteristics, electroencephalographic (EEG) electrode location and three signal processing methods on the spectral signal to noise ratio (SNR) of Steady State Visual Evoked Potentials (SSVEPs) with a view for use in Brain-Computer Interfaces (BCIs). It was hypothesised that the new spectral baseline processing method introduced here, termed the 'activity baseline', would result in an improved SNR.…”

Digital Replica for Trustworthy Cooperative Autonomous Vehicles by Farahat, Hady

“…Trust in an automated system can be defined as confidence in a vehicle's reliability, safety, and predictability, which is essential for the acceptance and widespread adoption of fully autonomous vehicles (FAVs); without it, users might disengage from using autonomous vehicles or reject the technology altogether. …”
