This study aimed to answer the questions: “What is the result of engaging directed attention when viewing otherwise restorative environments?” and “Does this intentional engagement have any effect on already fatiguing non-restorative environments?” Participants were asked to complete a task designed to fatigue their directed attentional capacity and then view images of restorative or non-restorative environments, wherein they either were asked to direct …
The Effects Of Reflective Prompts On Attention In Restorative And Non-Restorative Environments, Ryan Dumke
The Effects Of Reflective Prompts On Attention In Restorative And Non-Restorative Environments, Ryan Dumke
All-Inclusive List of Electronic Theses and Dissertations
Attention Restoration Theory (Kaplan, 1995) posits that the prolonged use of directed attention results in directed attention fatigue and that exposure to environments with restorative properties leads to increased attentional capacities. Despite a great deal of evidence illustrating this effect, there has been little research into the specific mechanisms accounting for this effect, and no research examining what is occurring in the mind during the restorative process. Most researchers have operated on the assumption that the relaxation of directed attention faculties accounts for the effect of attention restoration, with little evidence to completely support this assumption. However, conflicting evidence suggests …

Novel Phytol-Derived Immunostimulants (Phis-01) For Enhancement Of Vaccine Efficacy: A Comparative Study, Youssef Aachoui
All-Inclusive List of Electronic Theses and Dissertations
Adjuvants are used widely in vaccine formulations. However for humans, choices are very limited. Since they are selected empirically, it is not expected that any two adjuvants would influence immune mechanisms the same way. However they all influence host microenvironment, antigen presentation, and retention of immunological memory. This study focuses on new terpenoid adjuvants based on phytol derivatives. We previously observed that phytol and one of its derivatives PHIS-01 (a phytol-based immunostimulant, phytanol) are excellent adjuvants. To gain an understanding of the structural features important for adjuvanticity, we further studied compounds derived from a diterpene Phytol. We designed two new …
