Levels of employee motivation in a Swiss multinational speciality chemical company.
Thesis (MBA)-University of KwaZulu-Natal, 2006.In this dissertation the researcher investigates the levels of employee motivation and related contributing factors in his own organization. The researcher reviews and presents the results of a literature survey for the reasons of varying levels of employee motivation amongst staff in his own organisation a Swiss Specialty Chemical Multinational. The researcher identifies a theoretical framework that serves as a backdrop to the interpretation of the empirical results, by providing insight into employee motivation and the role of managers in addressing and improving employee motivation. The study investigated the relationship between intrinsic and extrinsic motivation factors and the extent of the existence of equity factors in the South African environment. Staff motivation in a multinational was analyzed from the perspective of Hertzberg-Hygiene Theory in the present study using survey data from all employees across the organization. An empirical survey examining how staff feels about issues such as working conditions, actual work, company policy & administration ,job security, job advancement ,supervision, recognition and remuneration. The researcher reported, analyzed, and interpreted the results of the data that were obtained via the questionnaires and that were captured using the statistical computer program SPSS 11.5. The empirical results and analysis of the fieldwork revealed that management must address key issues such as recognition, job security and advancement within the organisation in order to improve or increase levels of staff motivation. The issue regarding remuneration is always a sensitive and emotional topic; management must ensure that consistent and fair practice is instilled
Guidance and Control strategies for aerospace vehicles
A neighboring optimal guidance scheme was devised for a nonlinear dynamic system with stochastic inputs and perfect measurements as applicable to fuel optimal control of an aeroassisted orbital transfer vehicle. For the deterministic nonlinear dynamic system describing the atmospheric maneuver, a nominal trajectory was determined. Then, a neighboring, optimal guidance scheme was obtained for open loop and closed loop control configurations. Taking modelling uncertainties into account, a linear, stochastic, neighboring optimal guidance scheme was devised. Finally, the optimal trajectory was approximated as the sum of the deterministic nominal trajectory and the stochastic neighboring optimal solution. Numerical results are presented for a typical vehicle. A fuel-optimal control problem in aeroassisted noncoplanar orbital transfer is also addressed. The equations of motion for the atmospheric maneuver are nonlinear and the optimal (nominal) trajectory and control are obtained. In order to follow the nominal trajectory under actual conditions, a neighboring optimum guidance scheme is designed using linear quadratic regulator theory for onboard real-time implementation. One of the state variables is used as the independent variable in reference to the time. The weighting matrices in the performance index are chosen by a combination of a heuristic method and an optimal modal approach. The necessary feedback control law is obtained in order to minimize the deviations from the nominal conditions

Study of insulin resistance and antioxidant vitamin status in prostate cancer patients
The incidence of prostate cancer is 5 per 100000 in southern and eastern Asia. Both genetic and environmental factors have been implicated in its etiology. The mitogenic and growth stimulatory effects of Insulin growth factor may be involved in prostate carcinogenesis. To evaluate serum insulin and insulin resistance was passed by HOMA- IR. Prostatic specific antigen passed by immune-enzymatic assay. Vitamins were estimated by high performance liquid chromatography. In our study 30 prostate cancer patients aged 60-80years were taken as cases. 30 normal age matched disease free person were taken as controls in both groups, Insulin resistance and antioxidant vitamin status was studied. In the present study, the value of HOMA-IR was (P <0.05) is significantly higher compare to controls. Serum vitamin E and vitamin C values for cases was reduced (P <0.05) significantly lower than controls. The development of prostate cancer is a multistep process. Hyperinsulinemia associated with insulin resistance may play a role in pathogenesis of prostate cancer. Prostate cancer cells generate high levels a ROS
Evaluating the rural health placements of the Rural Support Network at the Faculty of Health Sciences University of Cape
Objectives: The Rural Support Network (RSN) is an undergraduate student society that aims to raise awareness among the student body of the plight of rural health in South Africa, and organises individual and group placements in rural hospitals during vacations. This research aimed to evaluate these placements from the students' perspectives. Design: In-depth, face-to-face interviews were conducted with 10 students and nine placement-reflective reports were reviewed. The data were analysed and coded for key themes using a constant, comparative grounded theory approach. Setting: Faculty of Health Sciences (FHS) at the University of Cape Town. Subjects: Students who had been on RSN placements in 2010. Results: Students reported that the experience exceeded their expectations of learning new skills and observing and performing procedures. They gained significant insights into rural health care and were inspired to contribute to rural health in future. Their experiences helped them to gain confidence and an appreciation of the psycho-social aspects of patient care. The importance of community empowerment and of connecting and building relationships with communities was also emphasised. Challenges pertained to conflict within groups, incidents of unprofessional health care and being unable to help as much as they would have liked. Conclusion: The study highlights the impact that positive experiences of rural health may have on health science students' interest in, passion for, and commitment to practising in underserved rural areas. Students' key recommendations for the FHS included the development of a rural programme within the undergraduate curriculum. Better group composition and improved planning and co-ordination of placements by the RSN were also recommended
Planetary Bistatic Radar
Planetary radar observations offer the potential for probing the properties
of characteristics of solid bodies throughout the inner solar system and at
least as far as the orbit of Saturn. In addition to the direct scientific
value, precise orbital determinations can be obtained from planetary radar
observations, which are in turn valuable for mission planning or spacecraft
navigation and planetary defense. The next-generation Very Large Array would
not have to be equipped with a transmitter to be an important asset in the
world's planetary radar infrastructure. Bistatic radar, in which one antenna
transmits (e.g., Arecibo or Goldstone) and another receives, are used commonly
today, with the Green Bank Telescope (GBT) serving as a receiver. The improved
sensitivity of the ngVLA relative to the GBT would improve the signal-to-noise
ratios on many targets and increase the accessible volume specifically for
asteroids. Goldstone-ngVLA bistatic observations would have the potential of
rivaling the sensitivity of Arecibo, but with much wider sky access.Comment: 11 pages, 2 figures, To be published in the ASP Monograph Series,

Modification of silicon carbide fibers for use in SiC/Ti composites
The degradation of silicon carbide fibers during exposure to conditions typical of composite fabrication was investigated. The tensile strength of pristine fibers and fibers sputtered with thin metal coatings were determined before and after treatment at 870 C for one hour in vacuum. Each fiber strength distribution was related by an analytical procedure to a projected composite ultimate tensile strength (PC UTS). The results indicate that a thin aluminum diffusion barrier can yield a 150 percent increase in PC UTS over the baseline SiC/Ti system
Career and practice intentions of health science students at three South African health science faculties
Background. The distribution and accessibility of healthcare professionals as well as the quality of healthcare services are significantly affected by the career choices of medical and other health science graduates.Objective. While much has been reported on the career intentions of medical students, little is known about those of their counterparts in the health sciences. This study describes the career plans of non-medical health science students at three South African health science faculties, and identifies some key motivating factors.Methods. A self-administered survey of first- and final-year health science students was conducted at the health science faculties of the universities of Cape Town, KwaZulu-Natal and Limpopo. All data were entered into EpiData software and exported for analysis using IBM SPSS Statistics 19.0.Results and discussion. The overall response rate was 47% (N=816). Over half of all respondents (57%, n=467) intended to work after completing their undergraduate studies, 38% (n=177) of these in a rural area. The most popular choices were private hospitals (58%, n=273), tertiary hospitals (53%, n=249) and private practices (51%, n=249). Thirty-two per cent (n=258) of respondents intended to further their studies. Just over half of all respondents intended to work in another country (51%, n=418), primarily motivated by career development, financial reasons and job opportunities.Conclusion. The findings demonstrate that health science students, similar to medical students, are influenced by a multitude of factors in making career choices. This emphasises the relevance to all health science disciplines of national strategies to address the maldistribution of healthcare professionals
An exploration of the relationship between leadership styles and the implementation of transformation interventions.
The objective of this research was to determine whether a relationship exists between the way in which subordinates experience their managers’ leadership styles and the influence of such leadership styles on the implementation of transformation interventions. A two-phase triangulated research design was employed where the qualitative phase preceded the quantitative phase. Ninety six (N = 96) respondents from a mining company participated in the survey. Results indicate a statistical and meaningful correlation between Integrated Leadership styles and transformation interventions but no correlation between Directive Leadership and implementation of transformation interventions
Case studies to enhance online student evaluation: Bond University – Surveying students online to improve learning and teaching
One of the most sensible ways of improving learning and teaching is to ask the students for feedback. At the end of each teaching period (i.e. semester or term) all universities and many schools survey their students. Usually these surveys are managed online. Questions ask for student perceptions about teaching, assessment and workload. The survey administrators report four common problems
