D.Phil. / Efficient ocular saccadics with a clear visual memory are essential functions in reading fluently. A child needs to sequence the eyes in a controlled jump called a saccade in order to form a picture in the mind of what is being read. The child is therefore primarily aware of a story rather than individual words. This sequential visual input of the written text contributes to efficient reading skills. The letter sequencing therapy used in this research is designed to improve the ocular saccadics and also to simultaneously develop an efficient visual memory. This improves the reading skills and creates good comprehension. The above exercise program illustrated that visual therapy, in general, done not only as a physical exercise but by improving the visual memory, will integrate very quickly into a child's perceptual development. Visual therapy can therefore improve the learning skills in an effective and efficient manner. The development of learning skills can be expanded to benefit children that have poor reading skills as a result of cultural deprivation. Until recently, due to apartheid and cultural differences at the pre school level disadvantaged children were deprived of the same standard of education as advantaged children. This research compared the average visual skills in reading of educationally advantaged children to educationally disadvantaged children. This illustrated the gap created by apartheid, differences in culture and preschool stimulation in the two levels of education. 167 children with no particular learning or visual problems were randomly selected from a group of pupils at an average middle class educationally advantaged white school and an average middle class disadvantaged black school. 100 of the children came from two standard 2 and two standard 3 classes of the educationally advantaged school while 67 of the children came from one standard 2 and one standard 3 class of the educationally disadvantaged school. All the children were evaluated before the therapy program began with respect to ocular fixations, ocular regressions, reading rate, directional attack, span of recognition and relative efficiency. All the children were given letter sequencing therapy under supervision of the class teacher. Strict controls were applied.

This non-traditional dissertation surfaces how youth activists and their adult accomplices build intergenerational solidarity and challenge age-based power dynamics in their social movement collectives. These questions are investigated from the perspective of 10 youth organizers involved in counterhegemonic organizing movements in the United States, as well as 10 of their chosen adult accomplices. Through semistructured interviews and participatory multimodal methods, youth and adult organizers demonstrate that their solidarity relationships are forged through establishing trust and safety and processes of demonstrating mutuality and reciprocity. Furthermore, youth and adults navigate and attend to adultism in their organizing by participating in processes of naming power dynamics, checking for consent, and co-creation. This research contributes to a bottom-up understanding of youth organizing praxis in relation to larger cultural discourses and adultist systems, while identifying practical implications for intergenerational support.

We present an efficient algorithm for solving an interval coverage problem. Given n intervals of the same length on a line L and a line segment B on L, we want to move the intervals along L such that every point of B is covered by at least one interval and the sum of the moving distances of all intervals is minimized. As a fundamental computational geometry problem, it has applications in mobile sensor barrier coverage in wireless sensor networks. The previous work gave an O(n2) time algorithm for it. In this thesis, by discovering many interesting observations and developing new algorithmic techniques, we present an O(nlogn) time algorithm for this problem. We also show that Ω(n log n) is the lower bound for the time complexity. Therefore, our algorithm is optimal. Further, our observations and algorithmic techniques may be useful for solving other related problems.

yes / This paper brings together a number of theoretical and political interests we have with the concept of global movements and the alter-globalisation, anticapitalist, and social justice movements in particular (Chesters & Welsh, 2004, 2005, 2006). The argument contained in this paper is that these movements are the emergent outcome of complex processes of interaction, encounter and exchange facilitated and mediated by new technologies of mobility and communication and they suggest the emergence of a post-representational cultural politics qualitatively different from the identity based social movements of the past.

The present dissertation explores the collective identity of the Anonymous movement. This movement is characterised by the heterogeneity of its activities, from meme-crafting to pranks to activist actions, with a wide range of goals and tactics. Such heterogeneity raises the question as to why such a diverse group of people makes the decision to act under the same name. To answer this question, the concept of collective identity is applied, which describes how participants collectively construct the definition of their group. This dissertation is based on a three-year ethnography. The main findings show that the collective identity of Anonymous rests on five sets of self-defining concepts related to: 1) Anonymous’ counterculture of offense and parrhesia, 2) its personification into two personae (the ‘trickster’ and the ‘hero’) that have differing goals, means, and relationships with the environment, 3) a horizontal organisation and a democratic decision-making process, 4) practices of anonymity and an ethics of self-effacement, and 5) its self-definition as a universal entity, inclusive, and unbounded. The collective identity construction process is marked by tensions due to the incompatibility of some of these concepts, but also due to differences between these collective identity definitions and actual practices. As a consequence, they have to be constantly reaffirmed through social actions and discourses. Not all individuals who reclaim themselves as Anonymous recognise the totality of these collective identity definitions, but they all accept a number of them that are sufficient to legitimate their own belonging to the movement, and most of the time to be recognised by others as such. The different groups constituting Anonymous are therefore symbolically linked through a web of collective identity definitions rather than an encompassing and unified collective identity. This ‘connective identity’ gives the movement a heterogeneous composition while at the same time permitting it to retain a sense of identity that explains the use of a collective name.

Many studies have found evidence of abnormal eye movement control in Parkinson's disease. Deficits in the inhibition of unintended saccades and slowed initiation of intentional saccades have been reported in some, but not all, investigations. Also over recent years the presence of cognitive impairment in a proportion of patients with Parkinson's disease has been highlighted. Efficient use of working memory resources is thought to be involved in the performance of tasks in both domains. With a comprehensive selection of saccadic and neuropsychological tasks, the current study investigated whether aspects of abnormal oculomotor control are associated with impairment of cognitive functions. Nineteen Parkinson's disease patients and eighteen healthy age matched control subjects performed six eye movement tasks and completed a neuropsychological test battery assessing five different aspects of cognitive functioning. Deficits were found in both the oculomotor and the cognitive domain in the group of patients. As a group, the patients made more reflexive errors in antisaccade tasks, more inhibition errors in a delayed response task, and were slower to initiate intentional saccades. The three measures of abnormal oculomotor control were not consistently associated with cognitive impairments or with each other. Longer latencies of correct antisaccades and increased number of errors in a delayed response task were associated with lower scores in different cognitive tests. Reflexive errors in the antisaccade task were not associated with cognitive deficits, but with the tendency to produce very fast visually triggered responses. The results suggest that, at least in Parkinson's disease, different neural mechanisms may be involved in specific aspects of abnormal oculomotor control.
