The work deals with the recording and reproduction of sound tracks on 16mm film and with old forgotten film optic sound technologies, as well as plans experiments and research, which examines possible methods for reading and writing tracks using modern optoelectronic devices. The final output is intended to drive the writing negative audio (analog and digital) on the photosensitive material and design of the device for synchronous playback of digital audio tracks from an external memory card. The work is done in collaboration with film laboratories Barrandov Studio a.s. and Meopta-Optika, spol. s r.o.

Text has abstracts in English, Afrikaans and isiZulu / Translators give us access to texts written in other languages, yet they remain mostly invisible to us. The translator’s preface therefore becomes the most important paratext where their voices are heard and where the text is identified as a translation. Research on South African paratexts is scarce and the study contributes to filling this gap. The aim of this study was to explore the nature of South African translatorial prefaces by determining the characteristics, content and functions of the prefaces and describing how translators are visible in their prefaces. A qualitative study was done where Genette’s (1997) conceptual framework was fitted into the overarching theory of Descriptive Translation Studies, making use of thematic analysis as described by Braun and Clarke (2013) to analyse the data. The data consisted of 65 South African literary texts with translatorial prefaces, published between 1945 and 2016 in the official South African languages. The study found that South African translators are mostly invisible through the absence of translatorial prefaces, but when they do write prefaces, they become highly visible and write about a wide variety of topics that make their prefaces a rich documentary source of valuable information for readers, translation studies students and scholars. The study provides a foundation for further research on South African translatorial prefaces. Translatorial prefaces should be included in the curricula for Translation Studies students and in a multilingual country like South Africa, no translation should be without a preface. Translators are encouraged to write comprehensive prefaces that will increase their visibility and situate translations in the polysystem of South African literature. / Vertalers gee ons toegang tot tekste wat in ander tale geskryf is, maar tog bly hulle meestal onsigbaar vir ons. Die vertalersvoorwoord word dus die belangrikste teks waar hul stemme gehoor kan word en waar die teks as ’n vertaling geïdentifiseer kan word. Navorsing oor Suid-Afrikaanse parateks is skaars en die studie dra daartoe by om hierdie leemte te vul. Die doel van die studie was om die aard van Suid-Afrikaanse vertalersvoorwoorde te ondersoek deur die kenmerke, inhoud en funksies van die voorwoorde te bepaal en te beskryf hoe vertalers sigbaar is in hulle voorwoorde. ’n Kwalitatiewe studie is gedoen waar die konseptuele raamwerk van Genette (1997) in die oorkoepelende teorie van Beskrywende Vertaalstudies toegepas is, met behulp van tematiese analise soos beskryf deur Braun en Clarke (2013) om die data te ontleed. Die data bestaan uit 65 Suid-Afrikaanse letterkundige tekste met vertalersvoorwoorde, wat tussen 1945 en 2016 in die amptelike Suid-Afrikaanse landstale gepubliseer is. Die studie het bevind dat Suid-Afrikaanse vertalers hoofsaaklik onsigbaar is deur die afwesigheid van vertalersvoorwoorde, maar wanneer hulle wel voorwoorde skryf, word hulle hoogs sigbaar en skryf hulle oor ’n wye verskeidenheid van onderwerpe wat hul voorwoorde ’n ryk dokumentêre bron van inligting vir lesers, studente in vertaalstudies en vakkundiges maak. Die studie bied ’n basis vir verdere navorsing oor Suid-Afrikaanse vertalersvoorwoorde. Vertalersvoorwoorde behoort opgeneem te word in die kurrikula van vertaalstudie studente en in ’n veeltalige land soos Suid-Afrika behoort geen vertaling sonder ’n vertalersvoorwoord te wees nie. Vertalers word aangemoedig om omvattende voorwoorde te skryf wat hul sigbaarheid sal verbeter en hul vertalings in die polisisteem van Suid-Afrikaanse letterkunde sal plaas. / Abaguquli beelwimi basenza sikwazi ukufikelela kwiimbalo ezifumaneka ngezinye iilwimi, kodwa bahlala befihlakele kuthi. Iimbulambethe zabaguli zilwimi ngoko ke ziba yingcaciso ebaluleke kakhulu ethi ibaveze ivakalise amazwi abo, kwaye yenza iimbalo ezo zibe nokuphawulwa okanye zichazwe njengeenguqulelo. Uphando malunga neembulambethe okanye iingabulazigcawu eMzantsi Afrika lunqabile kungoko olu phando lunegalelo ekuvaleni esi sikhewu. Injongo yolu phando kukuphonononga ubume beembulambethe zeenguqulelo ezifumaneka eMzantsi Afrika ngokufumanisa iimpawu zazo, umxholo kunye nemisebenzi yeembulambethe, kwakunye nokuchaza indlela abazibonakalisa ngayo abaguquli kwiimbulambethe zabo. Kwenziwe uphando lohlobo oluchazayo (qualitative), apho kuysetyenziswe inkqubosikhokelo yengqiqo kaGenette (1997) ndawonye nethiyori esisikhokelo yeziFundo zoGuqulo loLwimi eziChazayo (Descriptive Translation Studies), nolusebenzisa uhlahlelo lwethematiki njengoko luchaziwe nguBraun noClarke (2013) ekuhlalutyeni idatha. Idatha iqulathe iimbalo zoncwadi ezingama-65 zaseMzantsi Afrika ezineembulambethe zeenguqulelo ezapapashwa phakathi konyaka ka-1945 no-2016 ngeelwimi ezisemthethweni eMzantsi Afrika. Olu phando lufumanise ukuba abaguquli beelwimi ikakhulu, ababonakali ngenxa yokungabikho kweembulambethe zezi nguqulelo, kodwa xa bathe bazibhala iimbulambethe, bayabonakala kakhulu kunjalonje batsho babhale ngenqwaba yezihloko ezahlukeneyo nezenza iimbulambethe zabo zibe ngamaxwebhu angoovimba abaqulethe ubutyebi bolwazi olubalulekileyo kubafundi zincwadi, abafundi bezifundo zoguqulo kunye nezifundiswa. Olu phando lwakha isiseko solunye uphando olunokwenziwa ngeembulambethe zeenguqulelo zaseMzantsi Afrika. Ngolu phando kuhlatyw’ ikhwelo lokuba iimbulambethe zeenguqulelo zibe yinxalenye yekharityhulam yabafundi beziFundo zoGuqulo kananjalo, kwilizwe elineelwimi ngeelwimi njengoMzantsi Afrika, makungabikho nguqulelo ingenambulambethe. Abaguquli bayakhuthazwa ukuba babhale iimbulambethe ezityebileyo eziya kubatyhila ngakumbi babonakale kubafundi neziya kubeka iinguqulelo kwisixokelelwano soluhlu loncwadi lwaseMzantsi Afrika. / Linguistics and Modern Languages / M.A. (Linguistics)

This study examined the validity of the South African Police Service (SAPS) multiple stressor intervention. The multiple stressor was developed for members of their specialised units to address Post Traumatic Stress Disorder (PTSD). Unfortunately, the SAPS multiple stressor intervention lacks scientific evidence to support its possible effectiveness in addressing PTSD. In the current study a deployment and intervention group was compared which employed a pre- test post-test design. The Davidson Trauma Scale and the Revised Impact of Event Scale measured PTSD globally, but also the PTSD dimensions of Intrusion, Avoidance/Numbing, and Hyperarousal. The Wilcoxon signed rank test results indicated that the intervention and deployment was both effective in addressing PTSD although the intervention group revealed the greatest improvement in their overall PTSD scores. The intervention group made significant progress in dealing with all three PTSD symptoms while the deployment group made less progress with their Intrusion and Avoidance/Numbing symptoms, but made significant progress with their Hyperarousal symptoms. The Mann-Whitney u test revealed no significant differences between the post intervention test scores of the two groups, either globally or on the three PTSD dimensions. It appears that deployment was just as effective as the multiple stressor intervention in addressing PTSD. / Psychology / M.A. (Psychology)

The Middle Fork John Day Basin in Northeastern Oregon is prime habitat for spring Chinook salmon and Steelhead trout. In 2008, a major tributary supporting rearing habitat, Big Boulder Creek, was restored to its historic mid-valley channel along a 1 km stretch of stream 800 m upstream of the mouth. Reduction of peak summer stream temperatures was among the goals of the restoration. Using Distributed Temperature Sensing (DTS) Fiber Optic Technology, stream temperature was monitored prior to restoration in June 2008, and after restoration in September 2008, July 2009, and August 2009. Data gathered was used to determine locations of groundwater and hyporheic inflow and to form a stream temperature model of the system. The model was used both to develop an evaluation method to interpret components of model performance, and to better understand the physical processes important to the study reach. A very clear decreasing trend in surface temperature was seen throughout each of the DTS stream temperature datasets in the downstream 500 m of the study reach. Observed reduction in temperature was 0.5°C (±0.10) in June 2008, 0.3°C (±0.37) in September 2008, 0.6°C (±0.25) in July 2009, and 0.2°C (±0.08) in August 2009. Groundwater inflow was calculated to be 3% of the streamflow for July 2009 and 1% during the August 2009 installation. Statistically significant locations of groundwater and hyporheic inflow were also determined. July 2009 data was used to model stream temperature of the 1 km (RMSE 0.28°C). The developed model performance evaluation method measures timelag, offset, and amplitude at a downstream observed or simulated point compared with the boundary condition, rather than evaluating the model based on error. These measures are particularly relevant to small scale models in which error may not be a true reflection of the ability of a model to correctly predict temperature. Breaking down model performance into these three predictive measures was a simple and graphic method to show the model's predictive capability without sorting through large amounts of data. To better understand the model and the stream system, a sensitivity analysis was conducted showing high sensitivity to streamflow, air temperature, groundwater inflow, and relative humidity. Somewhat surprisingly, solar radiation was among the lowest sensitivity. Furthermore, three model scenarios were run: a 25% reduction in water velocity, a 5°C increase in air temperature, and no groundwater inflow. Simulations of removal of groundwater inflows resulted in a 0.5°C increase in average temperature over the modeled time period at the downstream end, further illustrating the importance of groundwater in this stream system to reduce temperatures. / Graduation date: 2012
