Research report MMed 10 December 2018 / Background: Burnout is a response to prolonged stress and consists of three elements: Emotional Exhaustion (EE); Depersonalisation (DP); and Personal Accomplishment (PA). Existence of burnout under doctors is often not acknowledged but has major consequences for personal and professional life. Only limited research done regarding prevalence of burnout amongst registrars in South Africa. Objectives: To describe the prevalence of burnout, and asses for relationships between burnout and socio-demographic factors. Methods: A cross-sectional descriptive, internet survey was conducted. Respondents were registrars within the departments of the School of Clinical Medicine at the University of the Witwatersrand. To measure burnout the Mashlach Burnout Inventory (MBI) was used. Relationships were assessed by independent samples t-test and ANOVA. Results: Of the 585 successfully delivered questionnaires, 201 registrars started the survey (response rate of 34%). 170 questionnaires were analysed. The mean age of the respondents was 33 years, the male to female ratio was 1:1.8. The average score for EE was 3,5 (SD1.2), for DP 2.7 (SD1.1) and for PA 4.1 (SD1.1). The overall level of burnout was 84%. None of the respondents scored low over all categories. No significant association between socio-demographics and MBI dimensions was found. Conclusion: The prevalence levels found in this study was higher than found in national and international literature. Extremely high levels of DP were found. This is worrisome as DP affects professionalism and engagement of doctors. In keeping with international literature no associations were found with socio-demographic factors and burnout, suggesting the cause of burnout should truly be sought out in the work environment. Efforts to improve autonomy in the workspace, development opportunities and promoting peer collaboration, are needed to prevent of burnout. / E.K. 2019

With the constant scaling of semiconductor devices, reliability of these devices is a huge concern. One of the biggest reliability issues is a phenomenon known as electromigration (EM) [1] [2]. Electromigration is the transport of material caused by the gradual movement of the ions in a conductor due to the momentum transfer between conducting electrons and diffusing metal atoms [27]. The damage induced by electromigration appears as the formation of voids and hillocks, resulting in electrical discontinuity. Based on previous Electromigration research [15], I have created a tool chain that identifies where electromigration is likely to occur in large-scale integrated circuits. Using this tool chain, it is possible to identify the mean-time to failure (MTTF) of several common and high priority circuits such as complex adders and memories. Furthermore, this tool chain allows designers to isolate weak-points in these circuits to improve the overall MTTF of the circuit. The result is that with a few simple changes, circuits can be redesigned to increase the MTTF, at minimal cost to the system.

Whereas sex is a classification that is expected to remain consistent and stable over time, gender is more fluid and changes depending on one's culture, within culture, and in relation to the other gender. Our society suggests that all individuals fall neatly into one of two sex and gender categories; however there exists an entire community of individuals who, in fact, do not. Transgender individuals "express their gender in non-traditional ways and find their sense of self as female, male, or other to be in conflict with their assigned gender role" (Burdge, 2007, p.244). Disclosing as transgendered is a process of emergence that is not only an internal psychological process but is also a "relational and systemic dynamic that intimately involves family, friends, loved ones, and all social relationships" (Lev, 2005, p. 11). In this study, the disclosure experiences of male to female transgender individuals as well as the changes and adjustments that occurred in their relationships were explored through individual interviews. Thematic coding was used to analyze the data and identify themes in the disclosure experiences. Considering the experience from a systemic perspective, participants discussed the mutual impact of their disclosure on family, friends, acquaintances as well as greater systems including the medical field, mental health field, and other community agencies. / Master of Science

This study investigates a possible link between a students’ willingness to engage in out of class communication (OCC) with an instructor and the level of mediated immediacy that the instructor presents through his/her online presence. The hypotheses were that students viewing a Facebook page would be more willing to engage in OCC than those viewing an institutional web page with low levels of mediated immediacy and that students viewing a Facebook page would also be more willing to engage in OCC with their instructor for relationship focused reasons than those who viewed an institutional web page. While both hypotheses were found to be false, this study uncovered a correlation which suggests that the institutional web page creates a higher willingness to engage in OCC for task-focused reasons than a Facebook page and invites further research into the topic.

Many orthopedic conditions in dogs require the placement of bone screws in the proximal tibial metaphysis. Currently, both cortical and cancellous screws are used clinically depending on the surgeon’s preference; however, the ideal screw for use in the proximal tibia has not been determined. Currently, both the manual and power tapping techniques are used during surgical procedures of the proximal tibia in dogs. However, it is unknown if the use of power tapping when placing screws in the canine proximal tibial metaphysis affects screw purchase. Measurement of axial pull-out strength is traditionally used to evaluate and compare the holding power of screws inserted in bone. This study compares the axial pull-out strengths of 3.5 mm cortical and 4.0 mm cancellous screws inserted using manual and power tapping techniques in the proximal tibial metaphysis
