The fuzzball model of a black hole is an attempt to resolve the many paradoxes and puzzles of black hole physics that have revealed themselves over the last century. These badly behaved solutions of general relativity have given physicists one of the few laboratories to test candidate quantum theories of gravity. Though little is known about exactly what lies beyond the event horizon, and what the ultimate fate of matter that falls in to a black hole is, we know a few intriguing and elegant semi-classical results that have kept physicists occupied. Among these are the known black hole entropy and the Hawking radiation process.

This work examines the chemical and physical effects of a material treatment process on the biopolymers PEEK, POM-h, POM-c, PTFE and UHMWPE. The polymers are analyzed physically and chemically using atomic force microscopy, profilometry, scanning electron microscopy, optical microscopy, contact angle measurement, FT infra-red spectroscopy and energy dispersive X-ray spectrometry. PEEK is found to be the most suitable polymer and FT Infra-red spectroscopy an informative analytic tool.

Paper discusses the expected uncertainty of orbital parameters of binary stars as measured by the space-based gravitational wave observatory LISA (Laser Interferometer Space Antenna) and how the inclusion of spin in the model of the binary stars affects the uncertainty. The uncertainties are found by calculating the received gravitational wave from a binary pair and then performing a linear least-squares parameter estimation. The case of a 1500 solar mass black hole that is 20 years from coalescing with a 1000 solar mass black hole--both of which are 50 x 10^6 light years away--is analyzed, and the results show that the inclusion of spin has a negligible effect upon the angular resolution of LISA but can increase the accuracy in mass and distance measurements by factors of 15 and 65, respectively.

This study examined the language socialization of international students in the graduate school context of a western Canadian university. Focusing on one pervasive speech event, academic presentations (APs), this study explored the role this socioculturally organized activity played in facilitating students' linguistic and sociocultural development, and how it aided them in negotiating their entry into the academic world. The participants in this study included 55 graduate students and nine course instructors. Thirty seven students were native speakers (NSs) of English, while the remaining 18- -the focal participants of this study—were non-native speakers of English (NNSs). The sites were seven graduate courses in six different departments in three different faculties (Faculty of Medicine, Faculty o f Arts, and Faculty o f Applied Science). A qualitative approach was employed, and thus multiple kinds of data were gathered over a four-month period. Data collection methods included: (a) open-ended interviews with participants; (b) tape-recorded observations of APs; (c) researcher's fieldnotes of APs; and (d) collection of written documents (e.g., course outlines). Data were analyzed following Bogdan and Biklen (1992) by identifying major and minor themes while iteratively going over the data. A comparison of APs across disciplines is included, examining aspects such as A P content, sequence, length, and format. As well, an analysis of the qualities promoted in each field and of the multiple purposes APs fulfil is provided and related to the complex socialization (i.e., both linguistic and sociocultural) of international graduate students. Findings of the study suggested that APs are a complex task whose meaning is not fixed, but rather is determined by the interplay of the broad context of the academic world, the micro-context of each community of practice, and ultimately by each individual. With regard to the language socialization 6f NNSs, APs challenged students in both linguistic and sociocultural ways. However, by observing, participating in, and reflecting on APs, students gained increased membership and competence within their academic communities. / Education, Faculty of / Language and Literacy Education (LLED), Department of / Graduate

Increasing involvement with students at the University of Namibia has indicated their overall difficulty with comprehending and recalling information from oral content lectures. It has also been observed that in general very little attention is given to the development of listening skills in L2 ESP and EAP courses. For this study, I conducted a quasi-experiment to determine whether the recognition and interpretation of discourse markers will enhance students' listening comprehension in academic lectures. Students were tested to determine their comprehension of content information in a video-taped lecture. Qualitative data were collected by means of a questionnaire. After an intervention period of eight weeks, where the experimental group received strategy training in the recognition and interpretation of discourse markers in spoken texts, both groups were again tested. Their results were statistically compared. I also looked at related findings of other researchers. Finally, aspects for possible future research will also be considered. / English Studies / MA - (Specialisation in TESOL)

Submitted in fulfillment of the requirements for the Degree of Magister Technologiae: Human Resources Management, Durban University of Technology, 2012. / The research project focussed on the effectiveness of an induction programme for newly appointed staff at Coastal KZN FET College in Kwa-Zulu Natal. The main aim of the study was to investigate the perceptions of educators with regard to the effectiveness of the induction programme for newly appointed lecturers. The key findings of the research were that newly appointed lecturers experienced various problems. The study also explored experiences faced by newly appointed lecturers at Coastal KZN FET College. The challenges arise from the lack of an effective induction programme. These problems resulted in poor productivity among newly appointed lecturers. The empirical component underpinned the review and analysis of the effectiveness of an induction programme for newly-appointed lecturers as they adjust to their entry into the teaching profession. The study also investigated the high turnover (lecturer attrition) among newly appointed lecturers as well as the possible solutions which can be implemented. The survey method was used to administer the questionnaire to all 45 target respondents using the personal method. The study adopted the quantitative research method with precoded close ended questions. The personal method was used to administer the questionnaire to all 45 target respondent and in this way a high response rate of 100% was obtained. An important finding in this regard was that the induction programme was not evaluated and improved frequently. The induction programme should ensure that new lecturers are treated with dignity and are allowed the opportunity to display their strengths and the knowledge they bring to their new College by implementing an effective induction programme. Arising out of the empirical analysis the researcher has recommended and developed a set of guidelines which could be used in developing an effective induction programme for the Coastal FET College in Kwa-Zulu Natal. The study concludes with directions for future research to expand on the body of knowledge in this field. / M

Students in tertiary educational institutions in South Africa come from many different backgrounds and have varied educational experiences. Some students, especially those from non-English speaking backgrounds, may encounter linguistic difficulties with various academic tasks. In order for students to be successful at university, they must become academically literate. That is, they must master all the reading, writing, listening and comprehension tasks required by the disciplines in which they are studying. One such task is presented by the academic lecture which is an integral part of any course of study. Linguistically, the academic lecture can be seen as a particular genre with unique characteristics. This study investigated some linguistic characteristics of academic lectures. The discipline of Political Science, as a Social Science, was chosen because there is little research that has been done on language in the Social Sciences. The Political Science sub-disciplines of Political Philosophy, South African Politics, and International Relations were used in this research. First year lectures were recorded from each of these three sub-disciplines. The linguistic characteristics of lectures were analysed using techniques drawn from Systemic Functional linguistic theory. The analysis concentrated on the aspects mode and field as they were realised in the lectures. In addition, higher level generic structure was also analysed. The insights gained from the analysis were validated through interviews with the lecturers who gave the lectures. The aim of this research was to develop a linguistic characterisation of the lecture genre as it occurs in the three sub-disciplines of Political Science. The results of this research suggest that although there is a unified academic lecture genre, there is variation according to sub-discipline. The implications of this variation are discussed with reference to their relevance to teaching academic literacy.
