OBJECTIVE: Simulation offers an important avenue for surgical and anesthesia training. This is especially important for crisis management scenarios where individuals need to act quickly and efficiently for optimal patient care. Practice based performance can be measured and real time feedback provided during debriefing scenarios. METHODS: In this paper, we highlight a dual anesthesia and otolaryngology cavernous carotid injury scenario. The trials were run three different times with inter-trial debriefing. RESULTS: The focused debriefing improved resident performance in terms of blood loss on subsequent trials. Furthermore, the learners provided important feedback regarding the utility of training and how it improved their ability to handle crisis management scenarios in the future. CONCLUSION: Debriefing for crisis management in a simulation trial improves performance and trainee confidence. Follow up studies will evaluate real world effectiveness over a longer follow up period.

Published Article / Despite the introduction of various legislative measures to improve the performance of local government in terms of the mandate to be an autonomous sphere of government, service delivery in South Africa remains questionable and local government in a quandary. Performance in this context is influenced by globalization, technological development and challenges such as the world-wide financial crisis, enforcement of debt collection policies, decaying infrastructure and an unresponsive political and administrative environment. Strategies are recommended to ensure that local government can move beyond this point to excellent service delivery.

The goal of the dissertation study was to evaluate the existing DG scheduling algorithm. The evaluation was developed through previously explored simulated analyses of DGs performed by researchers in the field of DG scheduling optimization and to improve the current RT framework of the DG at TTU. The author analyzed the RT of an actual DG, thereby enabling other investigators to compare theoretical results with the results of this dissertation case study. Two statistical methods were used to formulate and validate predictive models: multiple linear regression and graphical exploratory data analysis techniques. Using both statistical methods, the author was able to determine that the theoretical model was able to predict the significance of four independent variables of resource fragmentation, computational volatility, resource management, and grid job scheduling on the dependent variables quality of service and job performance affecting RT. After an experimental case study analysis of the DG variables, the author identified the best DG resources to perform optimization of run-time performance of DG at TTU. The projected outcome of this investigation is the improved job scheduling techniques of the DG at TTU.

Globalisation is affecting all social sectors, including education in ways that was never thought of before. In South Africa the most changing environment is probably the education sector. Higher education institutions in particular are constantly forging ways to develop the human resource capital for the country despite the shrinking financial resources. The increased demand for quality education, greater efficiency, accountability and national viability constantly challenge academics such that they can no longer wait for management to provide them with the necessary skills and competences. The times are calling for academics to take initiatives to develop themselves for improved performance in their primary roles and in the education of the learners. This study was undertaken to determine the changing nature of radiography as a profession and field of specialization, the development needs of radiography educators and the preferred strategies that could be used to develop the necessary skills and competences. A qualitative research design was employed and data collected through the literature review and interviews. Unstructured questions were used in the interviews to obtain an in-depth understanding of the situation. Challenges faced by academic radiographers in South Africa were explored and new competences required by academe during the time of change explained. Focus was put on the primary functions of academe and that includes teaching, research, community service/service learning and learner supervision strategies that can be used to improve the role of academe were described. Conclusions and recommendations regarding human resource development of academe were drawn from the literature review and the empirical investigation. / Dissertation (MEd (Maximising Potential in Education and Training))--University of Pretoria, 2005. / Curriculum Studies / unrestricted

Over the last two centuries, there has been a continual evolution of how occupied rooms are heated, with inventors competing to design new heating devices. In particular, there is a wide range of convector types, which vary in shape, size, design, material, operating medium and application. With approximately 190 million convectors installed in the UK alone, the question arises regarding the dependencies on the efficiency of heat distribution through convector-induced filling flows. A standard approach to evaluate convector performance is based on the convector strength only, the implication being the stronger the convector the better the performance. This work has gone beyond the limits of a stereotypical assessment in pursuit of answers regarding the physics of convector-induced filling and a new objective method to evaluate the efficiency of this transient process. The ultimate goal has been to provide a deep understanding of filling and stratification induced by a convector, in order to heat rooms rapidly and effectively. An experimental facility has been designed that approximates dynamic similarity between the experimental set-up and a real-life room with a convector. In the experiments, a rectangular sectioned water tank represents a room and a saline source rectangular sectioned panel with sintered side walls provides a convector representation. Experiments have been performed in water with a saline solution to ensure high Rayleigh numbers. Diagnostic techniques involve a combination of a shadowgraph method, a dye-attenuation method, direct salinity measurements and a new application of Particle Image Velocimetry (PIV). Interesting insight into convector-induced buoyancy-driven flows has been gained. As a result, new guidelines aimed at heating rooms more rapidly and effectively have been proposed. The key outcome that can be immediately applied is that, for a given convector strength, heat distribution with height can be improved by adjusting the convector position. For instance, faster filling leading to more uniform heat distribution occurs in rooms with convectors detached from side walls, due to large-scale mixing flows in the early period of filling. Also shorter convectors relative to the room height, positioned close to the floor level, promote faster and more uniform filling. An attempt to describe the transient filling has been made and to do so statistical methods, application specific, have been developed. As a result, the empirical equations describing both the filling rates in different stages of filling and the development of stratification have been derived, which rank the governing parameters, based on their importance, as either dominant or subordinate. Two dominant parameters governing filling flows are the non-dimensional accumulation parameter B and the Rayleigh number ΔRa, which are related to the convector strength. The impact of these two parameters is constant throughout the process. The parameters accounting for the system geometry and filling time (T) are subordinate parameters. Their impact, visible in the early period, decreases as filling continues.

全權委託投資業務(俗稱代客操作),在證券市場中提供專業投資管理服務。我國證期會於民國81年，政策性地決定將開放此項業務。雖然整個規範體系已在民國87年建立，但它忽略掉經濟層面之考量，勢必造成全權委託投資契約無效率。 目前規範體系所允許之委託報酬的計算方法，稱之為「固定佣金制度」，由於此制度無法對業者提供經濟誘因，它會引發業者有嚴重之道德危險發生。因此，為解決誘因問題，應該使用「績效佣金制度」，不過在目前股市環境下，此一制度則引入過高之風險。因此，為解決兩種制度所帶來之問題，本文提出「改良式績效佣金制度」，在此制度下，委託報酬除基於傳統財務績效衡量值外，並基於非財務性績效衡量值，本文稱之為前瞻性績效衡量值（簡稱F-LPM）。 本文使用兩期之「主理人-代理人」模型，推導出最適委託報酬制度以及相關之比較靜態。在基本模式之下，本文進一步探討F-LPM之相關屬性及功能。所得結果與相關文獻一致，首先是，在最適委託報酬制度下，納入F-LPM可降低業者過度地重視短期，因而犧牲了委任人之報酬，這表示F-LPM具有增額資訊內涵。其次，無成本地提高F-LPM之精確度，可增加委任人之報酬。最後，改良式績效佣金制度優於固定佣金制度與績效佣金制度，因為它可降低風險，因而帶給委任人之報酬增加。 第壹章 緒論 第一節 / Discretion account business provides professional investment management service in the securities market. The Securities and Futures Commission decides in policy to approve the business in 1992. Althrough the regulation system of the discretion account business has been established, it will make the advisory contract inefficient with the negligence of economic consideration. The form of advisory fees permitted by the regulation system is 'constant fee system'. Under the system, advisory contract provides no incentive and serious moral harazd will occur. In order to solve the motivation problem, 'performance fee system' should be used. Under the circumstance of Taipei securities market, however, the performance fee system will bring in high risk. Hence, this paper suggests the 'improved performance fee system' to overcome the dilemma born by the performance fee system. In the improved system, advisory fees are based on the traditional performance measure and the fordward-looking performance measure (hereafter F-LPM). With a two-period principal-agent model, this paper develops the optimal reward system and related comparative static. Following the basic model, the paper examines the attributes and function of F-LPM. The findings are consistent with the related literature. First, the inclusion of a F-LPM in reward system can mitigate the potential for the advisor to focus excessively on the short-term at the expense of the investor. That is, F-LPM is incremental informative. Second, costless increases in precision of F-LPM will lead to increase in payoffs for the inveator. Finally, the improved performance fee system is superior to the constant fee system and the performance fee system in that it can reduce risk and results in higher payoffs to the investor.
