Due to the research on cosmic-rays in the 1930's, the Carnegie Institute in Washington DC instigated the construction of cosmic-ray observation centers around the world. Cosmic-ray activity was recorded using the model C cosmic-ray ionization chamber which uses a Lindemann electrometer. The shadow of the electrometer needle was projected onto a continuously moving strip of 60 mm photographic paper. Hour markers were recorded by dimming the lamp for three minutes at the start of each hour, while also grounding the ionization chamber. By grounding the ionization chamber the electrometer needle was returned to the zero position. Six ionization chambers were built and installed at six stations around the world. Approximately 114 station-years of data were recorded. Photographic paper moved about 25 mm an hour giving approximately a 25 km strip of photographic record. It is important to digitize these recordings in order to preserve them for further study of cosmic-rays from this time period. The digitizing of cosmic-ray recordings involves the process of transforming the recording image into numbers. Binarizing these recordings will also preserve it in a clear format enabling future research. This study is an attempt to prove that these historic cosmic-ray recordings can be digitized by using image processing techniques. Each foreground element of the recordings; the hour markers, calibration lines and data sequence is segmented. By using these segmented images, the recordings are digitized into meaningful numbers. The study begins with a brief introduction on cosmic-rays as they are recorded today, and how they were recorded before the 1950's. Important events in the area of cosmicrays, ground level enhancements (GLE's), are also introduced. Four of these GLE's were only recorded by the old model C cosmic ray ionization chambers. To show that it is indeed possible to digitize the historic cosmic-ray recordings, two research methodologies are used: A literature study of image processing techniques thought to be helpful in segmenting the foreground elements of the recordings and experimentation with these techniques. Experimentation is the primary research methodology. Existing techniques are used and adapted to segment the foreground elements of the recordings. New techniques are also developed. The iterative experimental phase is discussed in detail as an algorithm is formed to successfully digitize the historic cosmic-ray recordings. The study concludes with an interpretation of the results obtained in the experimental phase. The success of the algorithm is measured and future studies are introduced. In the end it is indeed shown that historic cosmic-ray recordings can be digitized by implementing image processing techniques. / Thesis (M.Sc.

The combined study of consumer ethnocentrism and lifestyle is a unique approach that marketers can use to determine consumer buying behaviour and to refine market segmentation. In particular, marketers need to study consumer buying behaviour and examine the main influences regarding what, where, when and how consumers buy, as this knowledge will allow marketers to predict how consumers make their purchase decisions and how they will respond to various marketing strategies. A better understanding of the buying behaviour of consumers in a prospective market segment will help marketers to devise more effective marketing strategies for targeting consumers in the particular market segment they wish to pursue, and therefore, market segmentation is an extremely useful marketing tool. The Black Diamond consumer segment in South Africa has been receiving heightened attention from marketers recently due to the increasing purchasing power of this segment, and therefore it is necessary for marketers to gain a more profound understanding of these consumers so that they will be able to address Black Diamonds' specific needs, wants and preferences. This will assist marketers to devise marketing strategies that target the Black Diamond segment more effectively. The primary objective of this study was to determine consumer ethnocentrism and lifestyle among Black Diamonds in Sandton. This objective was addressed by using an adapted version of the Consumer Ethnocentrism Scale (CETSCALE) to measure the level of consumer ethnocentrism among Black Diamonds and by determining the lifestyle of this group by using the activities, interests and opinions (AIO) approach to measure the levels of six lifestyle dimensions, namely fashion consciousness, self–consciousness, health consciousness, homemaking, community orientation, and cost–consciousness. Based on literature consulted, an interviewer–administered questionnaire was developed and distributed to Black Diamond consumers by five fieldworkers in the Sandton area, in the city of Johannesburg, in the Gauteng province. Convenience and judgement sampling (non–probability sampling methods) were used and a total of 200 respondents participated in this study. The validity and reliability of the adapted version of the CETSCALE used in the questionnaire to measure the level of consumer ethnocentrism of respondents, as well as the six batteries of statements used to measure the levels of the respective lifestyle dimensions, were determined by means of factor analysis. The results indicated that consumer ethnocentrism is moderately high among respondents. Furthermore, moderately high levels of fashion consciousness, self–consciousness, health consciousness and cost–consciousness were found among respondents. Low levels of interest were established in homemaking activities and community orientation. It was found that various underlying relationships exist between consumer ethnocentrism and lifestyle dimensions of respondents, specifically between the lifestyle dimensions of health consciousness, homemaking and community orientation. It was further found that significant differences exist between the perceptions of respondents toward consumer ethnocentrism and the lifestyle dimensions in terms of their diverse age categories. It is recommended that marketers should stress product attributes, benefits, and superior aspects of the product by underplaying the product's country of origin, in light of the high level of consumer ethnocentrism prevalent among Black Diamonds. Furthermore, it is recommended that marketers and organisations should adapt and modify their current marketing strategies in order to appeal to the various lifestyle dimensions of Black Diamonds, specifically focussing on the higher levels of fashion consciousness, self–consciousness, health consciousness and cost–consciousness among Black Diamonds, whilst underplaying homemaking and community orientation. By considering consumer ethnocentrism and lifestyle, and realising that these factors affect the buying behaviour of Black Diamonds, marketers will be able to develop effective marketing strategies that will allow them to target the Black Diamond consumer segment more effectively and efficiently. Recommendations for future research include examining consumer ethnocentrism and lifestyle among Black Diamonds in a wider geographic area, drawing a larger sample size from the target population, and being more selective with regard to the respondents included in the study, in order to ensure that the most appropriate respondents do indeed form part of population under scrutiny. Furthermore, in order to improve the validity of the study, future research could be conducted by incorporating more qualitative forms of research such as focus groups and interviews. In addition to the six lifestyle dimensions that were measured in this study, a wider range of lifestyle dimensions can be measured in future research. / Thesis (M.Com.

Tourism comprises the world's largest industry, and beaches (marine tourism) are considered as one of the major tourism attractions in the world. Marine tourism includes different aspects such as the ocean, coastal water sports, hotels and restaurants, island and beach resorts, recreation, fishing boat operators, cruise ships and charter yacht companies. One of the main contributors to marine and wildlife tourism in South Africa, is South African National Parks (SANParks), comprising of 21 national parks. Of the 21 National Parks six are marine national parks covering 4004.4 square kilometres namely West Coast, Wilderness, Tsitsikamma, Addo Elephant, Agulhas and Table Mountain National Parks. The two most known Marine National Parks in South Africa are Tsitsikamma and Addo Elephant National Parks: Addo Elephant for the fact that it is the only national park in South Africa hosting the BIG 7, namely elephant, rhino, lion, buffalo, leopard, whales and great white sharks. Tsitsikamma National Park is important as it is the first and oldest Marine National Park in Africa. South African National Parks receive thousands of visitors each year and tourists visiting these parks are a source of revenue for national parks and by determining travel motives, marketing can be undertaken more effectively, and specific factors can be taken into account when the marketing strategies are being planned. The literature review indicated that an understanding of tourist motives is a key aspect in understanding tourist behaviour. If the travel motives of tourists are known to product owners, in the case of South African National Parks, they will assist the product owner with product development as well as its marketing strategy. By understanding tourist behaviour one can understand why tourists buy certain products and why they make certain decisions. Tourist behaviour can be analysed in terms of the purchasing process a tourist goes through when making a decision. Different tourists will have different decision making processes and will have different motives for buying different products and services. To be able to understand how buyers proceed through the decision making process one has to look at the tourist decision–making process which consists of different influences like demographic factors, the marketing mix, internal/ psychological, external/social and situational factors. From the literature review, the following travel motivations theories were identified: Maslow's hierarchy of needs, Murray's classification of needs, Mill and Morrison's needs and wants theory, Push and Pull theories and the Sun lust and Wanderlust theory. It was found in the literature review that there are some travel motives that are found in most of the nature based destinations such as “relaxation and escape”, “learn about nature” and “park attributes” to name but a few. The research, however, also found that travel motives are closely linked to what these destinations offer and it was also found that different marine destinations seem also to have different travel motives. The aim of this study is, therefore, to determine the travel motives of tourists to selected Marine National Parks in South Africa. Secondary data was used to determine the visitor's profile as well as the factor analysis on travel motives. Four hundred and eight questionnaires were administered to the Addo Elephant National Park and 495 to the Tsitsikamma National Park. The data analysis consisted of two parts, the first part was descriptive data and here the profile of the visitors to the two selected marine national parks was discussed. In the second part a factor analysis was conducted. The aim of a factor analysis is to reduce the data and to assist in the interpretation of the data. A factor analysis further describes the variance–covariance relationship among a number of variables in terms of a few underlying but unobservable random quantities, called factors. For this research a principal axis factor analysis with Oblimin with Kaiser Normalisation rotation was performed on the 22 travel motive items. The visitors' profiles for both the parks were quite similar except for the following: The largest percentage of the visitors to Tsitsikamma National Park were Afrikaans speaking and not as in the case of Addo Elephant National Park most tourists were English speaking, The major markets for Addo Elephant National Park, were the Western and Eastern Cape Provinces and for the Tsitsikamma National Park the major markets were Gauteng and the Western Cape Provinces. The factor analysis regarding travel motives revealed the following four factors: Education and knowledge seeking, Relaxation and escape, Park attributes and Family togetherness. A comparison was done regarding the travel motives of tourists to the two national parks to determine if there were any differences. A small to medium effect size was found for “relax and escape” and “education and learning about wildlife”, therefore, a small to medium statistical significant difference were found. This research confirmed that different marine destinations have different travel motives. Therefore, marketers can use this information and focus on individual marketing for each park based on the products they offer. / Thesis (M.Com.
