Chinese students' view on motivation to pursue postgraduate studies

Wen, Jiaxin, Sha, Di January 2014 (has links)
This study aimed to investigate the motivation of whether pursuing postgraduate study or not among Chinese students in Inner Mongolia University and Dalian Nationalities University. All in all fourteen specific questions were designed in the questionnaire. Psychodynamic theory, social cognitive theory and Bronfenbrenner’s ecological theory have been employed to analyze the data. The results indicate that students’ motivations to pursue postgraduate studies have both internal and external causes. For those who want to pursue postgraduate studies, the internal causes can be listed as following: a higher degree for a decent job and students’ thirst for knowledge. The external causes include peer influence and extra expectation to fulfill parents' dreams. Those who do not want to pursue postgraduate studies hold more than a different idea on the relation between a better job and a higher degree. They think they can find a good job without a higher degree, and higher education level will not make any difference.

The feasibility of hostile take-overs In South Africa

Masipha, Rathelele Bernard January 2019 (has links)
Since the dawn of democracy, South Africa has had ostensibly all of the essential elements that are assumed to be sufficient for a country to develop an active market for hostile takeovers, in other words dispersed shareholder ownership, depressed shareholding, and a United Kingdom- or United States-inspired regulatory framework. This has not gone unnoticed. But even with this essential element a wave of hostile takeovers has never hit South Africa. Renewed excitement surrounding hostile takeovers has been revived by the attempted takeover of Murray & Roberts by Aton. The conspiracy stalled when the bid was challenged by the independent board of directors of Murray & Roberts at the Takeover Regulation Panel (TRP) and opposed by the Competition Commission. It appears as if Murray & Roberts successfully defended the hostile takeover by Aton, thereby continuing the narrative that hostile takeovers seldom succeed in South Africa, which raises questions about the feasibility of hostile takeovers in South Africa. This is the enigma of hostile takeovers in South Africa which the study seeks to examine. The research argues that, by applying abstract theories derived from the Anglo- American experience, most outside observers have neglected to properly account for local, idiosyncratic, South African factors that have stifled the market for corporate control in South Africa. / Mini Dissertation (LLM) University of Pretoria, 2019. / Mercantile Law / LLM / Unrestricted

Development of a simulation tool for flight dynamics and control investigations of articulated VTOL unmanned aircraft

Saghafi, F. January 1996 (has links)
A simulation tool for flight dynamics and control investigations of three different Vertical Take Off and Landing (VTOL) unmanned aircraft configurations has been developed. A control concept has been proposed in order to take advantage of the fast response characteristics of the ordinary small engine/propeller propulsion systems in such aircraft, as well as replacing the complex rotors used previously in VTOL concepts for small unmanned aircraft. The simulation model has been established on the basis of the proposed concept so that it can also be used to study the feasibility of this idea. An Object-based methodology has been introduced so as to reduce the amount of aerodynamic required data for the simulation model. The equations of motion associated with the aircraft multibody system with ten degrees of freedom have been derived using the Newton-Euler method. The modelling of various subsystems including the propeller model, the airframe aerodynamics and the engine model has been carried out. A method for calculating the propellers' slipstream effects on the other components has been presented. Input data for the simulation model have been estimated, using different sources. The Advanced Continuous Simulation Language (ACSL) has been used for the programming of the mathematical model. A series of comprehensive tests have been carried out in order to demonstrate the validity of the simulation model. The ability of the simulation model to explain the aircraft modes of motion as well as to discover unknown nonlinear behaviours and to describe them has been demonstrated.

Motivations for Medication Disposal at Take-Back-Rx Events

Andrews, Matthew, Heath, William, Lewis, William, Boesen, Keith January 2013 (has links)
Class of 2013 Abstract / Specific Aims: The purpose of the study is to describe the reasons for medication disposals at Take-Back-Rx events and make inferences regarding medication adherence. Methods: Participants at Take-Back-Rx were invited to complete a survey that collected information on the participants current medical conditions, associated medications, unwanted medications, and demographic information. Main Results: The majority of participants were non-Hispanic White (89.2%) on Medicare (87.8%) with at least some college education (72.1%). The mean number of reasons listed for disposal was 2.25 and the majority of medications were expired (70%) or the dose/agent changed (47%). Conclusion: This study effectively described the reasons for medication disposals at Take-Back Rx events, but applicability to further patient populations may be limited due to shortcomings of the instrument.

Evaluation of Agents for the Suppression of Take-all of Wheat in Virginia in Greenhouse and Field Studies, and Characterization of Isolates of Gaeumannomyces graminis varieties

Crozier, James Brooks 21 December 1999 (has links)
Take-all of wheat, caused by Gaeumannomyces graminis var. tritici (Ggt ) is a problem wherever wheat is grown. Crop rotation is currently the only method for control. Our objectives were to develop a greenhouse bioassay and to evaluate the efficacy of mineral, chemical, and or biological agents for control, test promising agents in the field, and characterize Ggt isolates collected in Virginia. 'Jackson' soft red winter wheat seeds were planted in a Kempsville loam containing millet seed infested with Ggt or sterile millet seed in the greenhouse. Root necrosis ratings, and root and shoot weight were determined as a measure of disease severity. In the field, plots were set up with or without addition of Ggt inoculum. Effectiveness of nitrogen source, reduced manganese, and fungicide seed treatments to control take-all was determined. In greenhouse tests and in field trials plants did not yield better, significantly gain root and shoot weight due to either ammonium ions or reduced manganese, and the severity of root necrosis was not affected. Fungicide seed treatments did not significantly control take-all in the field. MON 65500, an experimental chemical, fungicides, and biological agents were tested either alone or in combination in the presence and absence of Ggt. Plants from seeds treated with MON 65500 alone or in combination with difenoconazole gained significantly greater root and shoot weight and in field trials had significantly greater grain yield over control plots. In greenhouse tests, two Bacillus spp. and a fluorescent pseudomonad were tested. Plants from bacteria-treated seeds gained root and shoot weight in only one of several tests. USDA-maintained bacterial isolates did not perform well in greenhouse bioassays or in the field, and plants from Gustafson-product-treated seed, including biological agents yielded poorly over two seasons in field trials. Little information is available on the variability of Ggt, with most information coming from Britain and Australia. Virginia and Montana Ggt, and Gga and Ggg (British isolates) were tested for virulence against 'Jackson' wheat in the greenhouse. Seeds were planted with two Ggt mycelial plugs or two sterile PDA plugs. Colony morphology, growth rates, and vegetative compatibility groups were determined. Growth rate per day and total growth was related to disease severity in greenhouse assays. For the first time, bacterial Rep primers were used to amplify Ggt DNA. Molecular techniques as well as chemical markers were used to study anastomosis between "incompatible" strains. A useful technique was developed to quickly induce perithecial formation on soybean pods which lead to ecological and agricultural concerns. / Ph. D.
