M.Ed. (Educational Management) / The teaching profession currently finds itself in a period of rapid changes and progress. This is particularly applicable to the management style and ingenuity required of educational leaders. It will therefore be incumbent upon the Head of Department: Afrikaans to keep up with latest development in management to provide quality teaching and learning. If teachers are to reach their optimum potential as educators, the Head of Department: Afrikaans must display the highest standard of supportive leadership. Analysis of the leadership task of the Head of Department: Afrikaans indicates that the modern view on leadership focuses on the potential to be found in the members of the Afrikaans Department. If the Head of Department: Afrikaans identifies himself with this viewpoint and if he applies his acquired leadership skills to this end, he will succeed in influencing his staff members to the extent that this positive motivation becomes manifested in those staff members who manage to sustain a high level of dedication in their work situation without constant monitoring. It is also imperative for the Head of Department: Afrikaans to become aware of the most effective leadership principles in both theory and practice. The leader that strives to create an open work climate, will receive the benefits of total participation as well as improved interpersonal relationships between himself and his staff members in the department. Apart from the climate that needs to be open and easy, it is also important that the leader should consider the specific situation in which they interact as a work group as a determining factor in the choice, and practice, of leadership styles. The congruency leadership model of Nicholls proves exceptionally appropriate in this regard. Another responsibility of the Head of Department: Afrikaans will be to attain a high degree of functional efficiency within his department. In this regard it will also be necessary for him to be proficient in an appropriate leadership style. The Principal of the school needs to delegate some leadership responsibility to the Head of Department: Afrikaans to the extent that he will fulfill a supportive role. Formal, standardised supervision should make way for a more fluent, ennobling way of supervision. In the light of the aforegoing statement, the real value of clinical supervision as the primary leadership role of the DSA rests upon his ability to facilitate the professional development of staff members and to improve their teaching skills.

The problem of this thesis is to determine what affiliated courses are most frequently offered to the students who attend the regular four year high schools in Texas, and to determine the relationship of the subjects taught to the scholastic population of the school.

The purpose of this study is to make a survey of the libraries of sixty-six selected high schools of Texas to determine the present status of these libraries and how they measure up to the requirements set up by the Association of Colleges and Secondary Schools of the Southern States and by individual authorities.

Binge Eating Disorder (BED) is a deadly, psychiatric condition which affects about 10 million people in the USA. It is characterized by discrete and recurrent binge eating episodes consisting of rapid consumption of excessive amounts of highly palatable, energy-dense food (e.g. rich in sugars and fats) within discrete periods of time. Our laboratory has been focusing on the understanding of the behavioral, metabolic, and neurobiological factors underlying BED, through the development of an animal model of binge-like eating. This model is based on a limited access schedule in which rats are exposed 1-hour/day to a high-sucrose diet (HSD) in operant conditioning self-administration boxes. However, the consummatory and metabolic outcomes of exposing rats to a high-fat diet (HFD) in the same procedure are unknown. The aim of this thesis was to test the consummatory and metabolic effects of 1-hour limited access to either a HSD or a HFD in an operant rat model of binge-like eating. For this purpose, female rats were subjects of the binge-like eating procedure by limiting access to a HSD, a HFD, or a standard Chow diet. Our results show that limiting access to either a HSD or a HFD promoted binge-like eating as compared to control Chow diet. HSD binge-like eating was based on a true increase in the amount of food consumed, that is, an increased eating rate. Such suggests increase in palatability and a decrease in the home-cage standard chow intake, likely due to a negative contrast effect. Conversely, binge-like eating of the high-fat diet resulted from passive energy consumption due to the high energy-density of the food. Also, HFD binge-like eating was accompanied by neither increased eating rate nor rejection of the home-cage chow. Moreover, while HSD rats consumed less energy than HFD rats, the former were more energy efficient and gained more body weight than the latter. These results provide information on how the quality of food can deeply influence the behavioral and metabolic outcomes of binge-like eating. / 2022-06-07T00:00:00Z

In the thesis we have defined what is understood as a high health organization, and this in comparison with what is commonly known as a high performance organization. While much research is undertaken around high performance organizations, little or no research is undertaken around high health organizations. The thesis attempts to find answers to what it takes to be or to become a high health organization, and how organizations could create such a place, or possibly better “space”. Indeed, a high health organization is not a place, a building, or on organizational structure; it is a state of mind, a purpose, a form of coherence. The work in this thesis is by definition multidisciplinary and systemic, rooted in three, for the purpose, complementary research areas. Workplace spirituality is slowly making its recognition in the management literature, though still too much as a discipline in itself. Ayurveda, the thousands of years old wisdom tradition around systemic health, living systems and purposefulness does get some attention in academic work, however mainly within its cultural roots (of India). Finally, systemic thinking, not really mainstream yet either, is a scientific discipline that did find its way in the sciences, but is much less popular and use in management studies. As argued, we think that in the intersection of workplace spirituality, Ayurveda and systemics, a real new concept of a high health organization is emerging. Key concepts identified in the introduction were consciousness and coherence, which they play an important role in the entire thesis. The prevailing management research is based on an ontology of materialism, while it is clear that workplace spirituality, Ayurveda and systemics do not necessarily fit such an ontology. We have commented on an ontology of non-materialism, based on complexity theory and in particular the understanding of complex adaptive systems. If we would like to explore the concept of a high health organization, an adequate ontology (and epistemology) is necessary. It is impossible to develop a non-materialistic concepts within a materialistic ontology. The consequence of this ontological choice for our research methods are multiple and innovative. Our research method goes beyond deterministic causality, and attempts to visualize entanglement. It can only be based on a much more systemic analysis than what we are used to, hence we use Artificial Neural Networks and Semantics as analytical tools. Based on the results of our field research, the high health organization in a nutshell has the following components: 1. A systemic, values-based vision is the lighthouse of the high health organization 2. Values, and in particular lived values, are the driver of the high health organization 3. Transparent, clear, respectful and non-violent communication is the binding factor 4. A knowledge and learning culture is the necessary condition for a healthy organization 5. Organisational consciousness in the organization is the sufficient condition

It is perceived that Moore's Law will prevail at least for the next decade, with continuous advancements of processing technologies for very-large-scale integrated (VLSI) circuits. Nano technology is driving VLSI circuits in a path of greater transistor integration, faster clock frequency, and lower operation voltage. This has imposed a new challenge for delivering high- quality power to modern processors. Power management technology is critical for transferring the required high current in a highly efficient way, and accurately regulating the sub-1V voltage in very fast dynamic transient response conditions. Furthermore, the VRs are limited in a given area and the power density is important to save the precious real estate of the motherboard. Based on the power delivery path model, the analysis results show that as long as the bandwidth can reach around 350 kHz, the bulk capacitor of the VR can be completely eliminated, which means significant savings in cost and real estate. Analysis also indicates that 650kHz bandwidth can reduce the number of the decoupling capacitor from 230 to 50 for future microprocessor case. Beyond 650kHz, the reduction is not obvious any more due to the parasitic components along the power delivery path. Following the vision of high bandwidth, the VRs need to operate at much higher frequency than today's practice. Unfortunately, the multiphase buck converter cannot benefit from it due to the low efficiency at high switching frequency. The extreme duty is the bottleneck. The extreme duty cycle increases VR switching loss, reverse recovery loss, and conduction loss; therefore makes the 12V-input VR efficiency drop a good deal when compared with 5V-input VR efficiency. Two-stage approach is proposed in this dissertation to solve this issue. The analysis shows that the two-stage conversion has much better high frequency capability than the conventional single stage VRs. Based on today's commercial devices, 2-MHz is realized by the hardware and 350kHz bandwidth is achieved to eliminate the output bulk capacitors. Further improvement based on future devices and several proposed methods of reducing switching loss and body diode loss can push the switching frequency up to 4MHz while maintaining good efficiency. Such a high frequency makes the high bandwidth design (650kHz) feasible. Hence, the output capacitance can be significantly reduced to save cost and real estate. The two-stage concept is also effective in laptop computer and 48V DPS applications. It has been experimentally proved that two-stage VR is able to achieve higher switching frequency than single stage not only at full load condition but also at light load condition by the proposed ABVP and AFP concept based on two-stage configuration. These unique control strategies make the two-stage approach even more attractive. As the two-stage approach is applied to 48V DPS applications, such as telecommunication system and server systems, more efficient and higher power density power supply can be achieved while greatly cut down the cost. Therefore, after the two-stage approach is proposed, it has been widely adopted by the industry. In order to further reduce the output capacitance, the power architecture of computer needs to be modified. Based on two-stage approach, one possible solution is to move the second stage VR up to the OLGA board. Based on this structure, the parasitics can be dramatically reduced and the number of the cavity capacitor is reduced from 50 to 14. By reducing ESL of the capacitor, the output capacitance could be further reduced. After that and based on two-stage approach again, VR+LR structure is discussed, which provides the opportunity to reduce the output capacitance and integrate the power supply with CPU. The feasibility is studied in this dissertation from both power loss reduction and output capacitance reduction perspectives. Experimental results prove that LR can significantly reduce the voltage spike while minimizing the output capacitance. As a conclusion, the two-stage approach is a promising solution for powering future processors. It is widely effective in computer and communication systems. Far beyond that, it provides a feasible platform for new architectures to power the future microprocessors. / Ph. D.
