The primary purpose of this study was to provide a better understanding of the typology and etiology of physical overactivity (hyperactivity) in ADHD. ADHD is uniquely characterized by inappropriate/excessive motor activity, yet motoric aspects of ADHD have been neglected in the research literature. Given high levels of intrusive/inappropriate motor behaviors and evidence that the neuropathology of ADHD involves frontal-striatal dysfunction, this study investigated the possibility that aspects of physical overactivity in ADHD could be a result of a “utilization behavior syndrome”. Theories of this utilization behavior that claim the syndrome results from an imbalance between medial (frontal; voluntary, goal-directed) and lateral (parietal/visual; automatic, reactive) motor systems were also addressed. Results revealed high levels of utilization behavior specifically characterize hyperactivity in ADHD, and that motor overactivity in ADHD is not simply a result of generally heightened activity levels. Levels of utilization behavior were statistically associated with severity of hyperactive symptomatology as reported by parents of children with ADHD. Furthermore, utilization behavior was significantly related to difficulties on tasks thought to be dependent on the functioning of the medial but not the lateral, motor system. This supports theories that utilization behavior, at least in ADHD, could be a result of disinhibition of the lateral motor system due to dysfunction within the medial motor system. / Graduate

Doctor of Philosophy / Department of Horticulture, Forestry, and Recreation Resources / Khatamian Houchang / This project investigated the physiological and biochemical responses of three grapevine genotypes to a deficit irrigation strategy termed partial rootzone drying (PRD). The principle objectives of the project were to (1) establish if the response to PRD is a unique vine physiological response; (2) to investigate the effect of PRD on berry maturation and composition; (3) effect of PRD on vine water-use efficiency; (4) investigate the hormonal signal involved in the PRD mechanism. In addition, the project investigated the adaptation of these three grapevine genotypes to Kansas climatic conditions. The irrigation project was conducted in both a greenhouse at Kansas State University, Manhattan, KS, and field conditions in an experimental vineyard at the John C. Pair Horticultural Research Center, Haysville, Kansas. The greenhouse study was replicated four times (6 months each run) and the field study ran from the 2005/2006 season through the 2006/2007 season. Application of PRD to vines resulted in a unique physiological response distinct from other established deficit irrigation procedures such as regulated deficit irrigation (RDI); however, the overall physiological responses of the vines were defined by the environmental conditions of the vineyard where the experiment occurred. Reduced water availability, low to medium vigor vines, restricted root development, and high evaporative demand were all factors in the vines response to PRD. Under these conditions, PRD did maintain the yield at deficit irrigation rates compared to fully irrigated vines, and was responsible for physiological changes in the vine that could have long-term implications for yield stability. The application of PRD resulted in an improvement in plant water status and maintenance of leaf function as measured by photosynthesis, stomatal conductance and leaf water potential throughout the season.

M.Tech. / Attention-deficit/hyperactivity disorder (ADHD) is a commonly diagnosed childhood disorder characterised by impulsivity, inattention and hyperactivity that manifests in early childhood. The symptoms of ADHD affect cognitive, behavioural, emotional and social functioning (Sadiq, 2007). Conventional treatment of this disorder is predominantly through the use of psycho-stimulants, with methylphenidate (Ritalin® and Concerta®) often considered the drug of choice. Concerns about potential adverse effects include anxiety, anorexia, tacchycardia, cardiac arrhythmias, palpitations, increased blood pressure, dysphoria, dizziness, growth suppression and dyskinesias (Sadock and Sadock, 2007). Dreyer (1996) mentions the irritability, fatigue and melancholy, which often follows the use of these medications. Parents concerned about the side effects and long term use of medications are increasingly seeking out alternatives to pharmacologic treatment (Sadiq, 2007). Homoeopathy is a therapeutic approach of preventing and treating disease; it consists of a medical philosophy based on defined laws and principles (Eizayaga, 1991). Homoeopathy is asserted to influence disease with the use of highly diluted substances; the specific remedy is chosen to correspond according to the characteristic individual symptoms of the patient presenting with ADHD (Frei, et al., 2006). The aim of this study was, by means of case studies, to determine the effect of the homoeopathic simillimum treatment using LM potency in children with Attention Deficit/ Hyperactivity Disorder. Ten children, males and females between the ages of 5 to 10 years old who had been diagnosed with ADHD and were on a balanced, restricted sugar, high complex carbohydrate diet - low in additives, preservatives and food dyes (Rothenberg, 1997) - were recruited via advertisements (Appendix C) in the Gauteng region with permission from specific remedial and primary schools (Appendix F). In addition, an advertisement (Appendix C) was displayed on the Attention Deficit and Hyperactivity Support group of South Africa (ADHASA) website (Appendix D) and in psychologist and occupational therapist practice rooms. The study took place at the University of Johannesburg, Homoeopathy Health Centre, as well as at the participant’s and researcher’s homes.

The aim of the thesis is to find possible connections between the financial results of public budgets and the course of the political cycle in the Czech Republic. The analysis for the period of 1993 - 2010 focuses initially on the development of the overall deficit; subsequently the development of selected items of public revenues and expenditures is investigated. A fundamental part of the work is the separation of the cyclical deficit, arising from fluctuations in economic activity and the structural deficit, which is produced through specific measures of government fiscal policy. The results of the analysis indicate that with the approaching elections, there was a greater release of the fiscal policy. During the second half of the electoral cycles have also been reported higher structural deficits. However, the differences are not high enough to be considered as statistically significant.
