Objective: To provide eye care services to the clients of the Worldwide Orphans Foundation, many of whom are orphans, vulnerable children, and their caregivers living with HIV/AIDS and are thus at risk for developing severe eye infirmities. Method: Patient health histories were …
Most internationalization theories and approaches developed within the framework of large companies have fallen short of explaining how and under what circumstances SMEs become internationalized. Consequently, research has been directed in recent years towards studying SMEs' int…
A small church for Kazakhs has begun in Western Kazakhstan. What will it take to develop a church planting movement that has the potential to sweep through the whole region? We believe that a movement is more likely to occur when it has integrated a clear common vision with bibl…
From the airport security guard monitoring luggage to the rushed commuter looking for their car keys, visual search is one of the most common requirements of our visual system. Despite its ubiquity, many aspects of visual search remain unaccounted for by computational models. Di…
The majority of previous research investigating the role of vision in controlling adaptive gait has predominantly focused on over-ground walking or obstacle negotiation. Thus there is a paucity of literature investigating visuomotor control of step descent. This thesis addressed…
The Muslim headscarf conceals the hair and other external features of a face. For this reason it may have implications for the recognition of such faces. The experiments reported in this thesis aimed to investigate anecdotal reports, which suggested that headscarf wearing female…
Gaze tracking technology is widely used in Human Computer Interaction applications such as in interfaces for assisting people with disabilities and for driver attention monitoring. However, commercially available gaze trackers are expensive and their performance deteriorates if …
Thanks to the advances in technology, people are storing a massive amount of visual information in the online databases. Today it is normal for a person to take a photo of an event with their smartphone and effortlessly upload it to a host domain. For later quick access, this en…
There has been a relatively recent rehabilitation of the visual in the study of Jewish culture, mostly in terms of the study of images and attitudes towards them. This thesis extends the recognition of the importance of visuality in Jewish studies by treating vision itself as a …
This thesis reports results from two research projects that deal with interrelationships between pigment genes, photopigments, ocular structure, and vision in rodents. The first of these is an investigation of cone photopigments in the Syrian hamster, while the second examines t…
Vision has long been the model for understanding cortical function. Great progress has been made in understanding the transformations that occur within some primary visual cortex (V1) layers, like the emergence of orientation selectivity in layer 4. Less is known about other V1 …
Chapter one provides a multifaceted panorama of the Genoese community in medieval Seville that helps to link Francisco Imperial, an early 15th century poet, to a group of foreigners and naturalized Castilian subjects who, despite their marginality, contributed greatly to the kin…
The overall purpose of this dissertation was to investigate the influence of visual disruption on measures of postural stability, specifically in anterior cruciate ligament reconstruction (ACLR) individuals. Each of the two studies included in this dissertation evaluated postura…
Background: Hearing and vision play an important role in physical, mental, and functional health. Less is known about the impact of deficits in hearing and vision, including dual sensory impairment (DSI), and causes of these sensory impairments on cognitive function. Objectives …
This thesis investigates the relationship between evolving modes of visual perception and the space of architecture. The design of architecture is intimately linked to the way space is imagined to be seen, and thus to the scientific and cultural understanding of vision. And yet,…
In order to develop more effective rehabilitative therapies for stroke patients, we must understand what biological barriers limit functional recovery. Here we study functional recovery after stroke in the visual domain where recovery can be easily quantified with visual field t…
