Peace processes require an opening to self and others — a willingness to confront what is and to vision beyond present challenges to a brighter future. This type of engagement is crucial for the peaceful development of healthy, functioning societies — societies such as Ukraine, a country thrust without preparation from regional Soviet status to independent country searching for democracy. Eighteen years post-Independence the Ukrainian parliament continues to flounder unsupported by citizens. Active participation in civic affairs required for democracy is unfamiliar for most Ukrainian citizens, having internalized centuries of divisive oppression under a series of authoritarian regimes. Democracy-building and peace-building require participant agency and voice; rising out of oppression, people often need support to speak about and transform their lived experiences. This study, cognizant of the centrality of gender analysis in any context, explored the roles women’s shared narrative, dialogue, and group-visioning play in the support of personal empowerment and bridge building between diverse communities. The study invited women from the European Union-focused Western region of Lviv, Ukraine and the more Soviet/Russian-identified Eastern region of Crimea, first to share their personal stories with the researcher and second, to meet in their regional groups to vision for themselves, their families, and Ukraine. The third phase of this study invited these diverse regional groups to meet in a neutral space, reflexively exploring their parallel processes, while in phase four participants reviewed their experiences of the study. Despite initial beliefs that they have little in common, women in both regions said study participation changed them. They found telling their stories “from beginning to end” allowed them to reflect upon their own values and strengths, and having connected with themselves and their roots, they were then able to reach out to others. Rather than looking for differences, participants sought ways to express a shared vision for an inclusive, functional, peace-building future for themselves, their families, and Ukraine as a whole.

The aim of the study was to investigate affirmative action as a mechanism for education reform in South Aftica. This investigation was prompted by political changes, which took place after the democratic elections of April 1994, impacting on the provisioning of education in South Africa. The South African education system and its institutions were confronted by many new laws and policies, including affirmative action programmes that had to be implemented. Structural changes like a unified and racially integrated education system came into being. Through literature and empirical studies it was found that race and gender discrimination was observable in all the education institutions in the RSA. Literature study revealed that neither arguments for, nor arguments against affirmative action should be overemphasized at the expense of the other. Both approaches supplemented and enriched each other. Applied correctly and managed well, the disadvantages of affirmative action can be overcome in the main. In this manner most of the injustices of the past can be corrected. It was established through literature study that, like in the USA, affirmative action in the RSA seems to be an option to eradicate the imbalances of the past in terms of race and gender. In the USA success was achieved by affirmative action programmes: The American population became more representative in terms of race and gender. On the other hand it was also established that the previously disadvantaged groups were over-represented. This led to the claim of reverse discrimination. The empirical method, namely using questionnaires, was successful in obtaining information about how education participants, especially at school level, were affected by the implementation of affirmative action policies. It also established how education participants felt and thought about their experiences and perceptions about the affirmative action mechanism for education reform. The study established that factors aimed at the equality of opportunity (also known as the soft approach) enjoyed preference to factors aimed at the equality of result (also known as the hard approach). In order to bring about the smooth education transformation it also established that for observable and radical changes to occur in the education system, factors aimed at the equality of result (the hard approach) should enjoy more attention than factors aimed at the equality of opportunity. Thus it was concluded that both the soft and the hard approaches were necessary to understand the controversial nature of affirmative action. A number of recommendations were made with regard to the research findings for stakeholders and officials to note. / Thesis (M.Ed.)--Potchefstroom University for Christian Higher Education, 2003

We examined the effects of keeping hand actions in working memory on the speed of naming handled objects. The features of the hand action and objects’ handle matched or mismatched on two dimensions: alignment (left vs. right), orientation (horizontal vs. vertical). For objects presented in their canonical upright position, the speed of naming was only slower when the actions were partially incongruent with the target object. For rotated objects, the effect was reversed. The pattern of results suggests that the identification system is more sensitive to the functional goal (i.e. the end state) of the rotated object in evoking action representations than the actions evoked by the depicted view (i.e. the beginning state). The findings, overall, strongly support the notion that action representations play a functional role in object identification. / Graduate / 0633 / 0623 / tlin23@gmail.com

Current concepts of hippocampal circuitry assume a large population of excitatory principal neurones whose activity is largely governed by a network of local-circuit GABAergic interneurones. The diversity of hippocampal local-circuit neurones and their synaptic control over principal cell activity was investigated in vitro, in order to define their synaptic connections and functional roles. Single and dual intracellular recordings were made from local-circuit neurones and pyramidal cells in area CA1 of the rat hippocampal slice. Interneurones were tentatively distinguished from pyramidal cells based on their firing as well as their membrane properties. Intracellular labelling of recorded cells with the marker biocytin revealed a diversity of cell types based on differential dendritic and axonal morphology and synaptic connections. The physiological data revealed that all types of interneurone tested evoked inhibitory postsynaptic potentials (IPSPs) in simultaneously recorded pyramidal cells. The IPSPs had fast rise and decay kinetics and the ones tested pharmacologically, were mediated by GABA_A receptors. Similarly, individual interneurones were also shown to innervate other local-circuit interneurones in addition to pyramidal cells, the evoked effects being qualitatively similar in both types of postsynaptic targets. The postsynaptic effect and functional role of one type of hippocampal interneurone, the basket cell, was investigated in greater detail. Basket cell-evoked IPSPs were reliable, but showed some frequency-dependent attenuation. Moreover, basket cell IPSPs were found to interact with intrinsic pyramidal cell conductances to elicit rebound depolarisations and facilitate action potential generation. More detailed investigation showed that basket and axo-axonic cells were particularly effective in entraining pyramidal cell firing and sub-threshold membrane potential oscillations. Through these powerfully tuned mechanisms, sub-types of local-circuit interneurone provide a powerful mechanism to synchronise the activity of pyramidal cells. These results demonstrate a remarkable diversity of GABAergic local-circuit neurones in the hippocampal CA1 area and suggest that specific subtypes of cell mediate different functions.

Recent evidence suggests audiovisual perception changes as one engages in action. Specifically, if an audiovisual illusion comprised of 2 flashes and 1 beep is presented during the high velocity portion of upper- limb movements, the influence of the auditory stimuli is subdued. The goal of this thesis was to examine if visuomotor regulation processes that rely on information obtained when the limb is traveling at a high velocity could explain this perceptual modulation. In the present study, to control for engagement in visuomotor regulation processes, vision of the environment was manipulated. In conditions without vision of the environment, participants did not show the noted modulation of the audiovisual illusion. Also, analysis of the movement trajectories and endpoint precision revealed that movements without vision were less controlled than movements performed with vision. These results suggest that engagement in visuomotor regulation processes can influence perception of certain audiovisual events during goal-directed action.

The thesis introduces a novel search paradigm, and explores a previously unreported behavioural error detectable in this paradigm. In particular, the ‘Unpacking Task’ is introduced – a search task in which participants use a computer mouse to sort through random heaps of items in order to locate a unique target. The task differs from traditional search paradigms by including an active motor component in addition to purely perceptual inspection. While completing this task, participants are often found to select and move the unique target item without recognizing it, at times continuing to make many additional moves before correcting the error. This ‘unpacking error’ is explored with perceptual, memory load, and instructional manipulations, evaluating eye-movements and motor characteristics in additional to traditional response time and error rate metrics. It is concluded that the unpacking error arises because perceptual and motor systems fail to adequately coordinate during completion of the task. In particular, the motor system is found to ‘process’ items (i.e., to select and discard them) more quickly than the perceptual system is able to reliably identify those same items. On those occasions where the motor system selects and rejects the target item before the perceptual system has had time to resolve its identity, the unpacking error results. These findings have important implications for naturalistic search, where motor interaction is common, and provide further insights into the conditions under which perceptual and motor systems will interact in a coordinated or an uncoordinated fashion.
