Effectiveness of managing the North West motor vehicles licencing revenue systems / Otsile Clutchia Senokwane

Senokwane, Otsile Clutricia January 2012 (has links)
The study intended to evaluate the effectiveness of managing the North West motor vehicles licensing revenue system in case of Department of Safety, Public Works in the North West Province with office in Mmabatho. Data was collected through telephone and e-mail questionnaire administered to the revenue section in the Department of Roads Safety and Public Works. A Sample size of 42 to which 44 copies of the questionnaire were dispatched returned all the questionnaires. The main findings revealed that the more knowledgeable the public the more they comply with policies. Tax incentives could be used to reduce health risk caused by car pollution. / Thesis (MBA) North-West University, Mafikeng Campus, 2012

Examining the influence of marginally modified constraints on motor behaviour

Gao, Naichun., 高乃春. January 2013 (has links)
The thesis examines the influence of visual misperceptions of the primary environmental constraints related to motor behaviour, and explores whether motor adaptation can be caused implicitly by introducing systematic, undetectable changes in key constraints in the performance environment. The first two experiments (Chapter 2) were conducted to determine if a simple manipulation of the height of the uprights can cause participants to perceive the dimensions of the rugby goalposts differently. The findings support the existence of a rugby goalpost illusion. Misperceptions of the dimensions of the goalposts may influence decisions about where to place the ball when converting a try. In Chapter 3, a series of experiments tested this hypothesis both in a laboratory setting and in real life games. Experiment 3 showed that narrow goalposts caused kickers to place the ball further from the try-line than wide goalposts. Furthermore, misperceptions of the uprights width induced by the rugby posts illusion caused kickers to place the ball differently when making kicks (Experiment 4). By introducing pitch-markings in Experiment 5, we tested whether the effect of the illusion is moderated by use of familiar cues in the environment. An observational study (Experiment 6) suggested that the influence of the rugby posts illusion, intimated in our experimental work, is not evident in real life. Both Chapters 4 and 5 were designed to examine whether very subtle changes in constraints in the environment can be used specifically to induce implicit motor learning. In Chapter 4, the smallest detectable difference between two levels of sensory stimulus was determined for simple line drawings representative of rugby goalpost uprights (Experiment 7) or crossbars (Experiment 8). The findings from Chapter 5 suggested that (implicit) motor adaptations might be caused by gradual incremental changes in environmental constraints. / published_or_final_version / Human Performance / Doctoral / Doctor of Philosophy

Motor imagery: does strategy matter?

Hovington, Cindy 27 August 2008 (has links)
Motor imagery requires individuals to form an internal representation of a specific action within working memory without any overt output. Motor imagery has proven effective in improving motor performance of specific skills. This study explored whether different motor imagery strategies influence corticospinal excitability in young (20-35 years) and older subjects (over 55 years). In addition, the effectiveness of these strategies in targeting modulations in motor cortical output and whether the hand “performing” the task was important were also examined. Motor imagery ability was measured using the Kinesthetic and Visual Imagery Questionnaire (KVIQ) and mental chronometry. Working memory including visuospatial, verbal and kinesthetic domains was measured by immediate serial recall. To determine the effect of imagery on corticospinal excitability transcranial magnetic stimulation (TMS) was applied over the contralateral motor cortex as subjects imagined abducting their index finger. Motor evoked potentials (MEPs) were recorded from first dorsal interosseous (FDI), abductor pollicis brevis and abductor digiti minimi muscles (ADM). As subjects performed motor imagery, they were guided by visual, auditory or a combination of visual and auditory cues. Strategies were introduced in randomized sequence interspersed with a rest and a muscle activation condition. Motor imagery ability and verbal working memory were comparable between young and older subjects (p > 0.05). In both groups, MEP amplitudes in the FDI muscle were significantly increased during motor imagery compared to rest regardless of the strategy used (p < 0.001). Visual cueing was the most effective at isolating facilitation to the target muscle (FDI), whereas with the auditory and combined strategies both FDI and ADM muscles generated MEPs that were comparable in amplitude (p > 0.05). TMS induced MEPs were greater in amplitude when the left hemisphere was stimulated during motor imagery of the right finger while being guided by either auditory or visual cueing. In combination, these findings suggest that motor imagery increases corticospinal excitability and the strategy used may serve to target the facilitation. / Thesis (Master, Rehabilitation Science) -- Queen's University, 2008-08-26 15:58:21.277
