The need for the study was prompted by discussions with my fellow photographers and friends that fewer people visited the Kruger National Park the last few years. Various reasons were given for it. I discussed it with Professors G. Puth and A. N. Schreuder, and members of the National Parks Board. Initially it was decided that a study should be done of why there was a decrease in the demand for accommodation in the Park, and how it could possibly be improved. Mr. P. Fearnhead and Professor A. N. Schreuder suggested that it would be better if a price sensitivity study should be done with a new computer program, namely conjoint analysis. This type of study has not been done in South Africa before. One of the major purposes of a conjoint analysis is to measure consumer preferences among competitive products and services. Basically it measures preferences of tourists by making trade-offs between five attributes and seventeen levels, and that consumers make complex decisions not on one factor alone but on several factors "jointly". Thus it was named conjoint analysis. Ranking a number of different combinations of attribute levels on a nine-point rating scale indicated their preferences. The results were then processed by a computer program, Conjoint Value Analysis (CVA), Version 2.0 system. They indicated their preferences by ranking a number of different combinations of attribute levels to give utility values for the attributes. Six representative camps (three large and three small ones) were used for a stratified sample of 428 respondents. The findings will give recommendations that can be used. AFRIKAANS : Die behoefte vir die studie is aangespoor deur gesprekke met my medefotograwe en vriende dat minder mense die Nasionale Kruger Wildtuin die laaste aantal jare besoek het. Veskeie redes is daarvoor gegee. Ek het dit met Professore G. Puth en A. N. Schreuder, en lede van die Nasionale Parkeraad bespreek. Oorspronklik is besluit dat 'n studie gedoen behoort te word oar hoekom daar 'n afname in die vraag vir akkommodasie in die Wildtuin was, en hoe dit moontlik verbeter kon word. Mnr. P. Fearnhead en Professor A. N. Schreuder het voorgestel dat dit beter sou wees indien 'n prysssensitiwiteit-studie met 'n nuwe rekenaarprogram, nl. gesamentlike analise ("conjoint analysis"), gedoen sou word. Hierdie tipe studie was nag nie voorheen in Suid-Afrika gedoen nie. Een van die hoof oogmerke van 'n gesamentlike analise is om verbruiksvoorkeure tussen mededingende produkte en dienste te meet. Basies meet dit voorkeure van toeriste deur kompromiee ("trade-offs") tussen vyf eienskappe en sewentien vlakke te maak, en dat verbruikers komplekse besluite maak nie oar een eienskap aileen nie, maar verskeie eienskappe gesamentlik ("jointly"). Daarom is dit gesamentlike analise ("conjoint analysis") genoem. Hulle voorkeure word gewys deur die toekenning van 'n rangorde aan 'n aantal veskillende kombinasies van eienskap-vlakke op 'n nege-punt skattingskaal. Die resultate is daarna deur 'n rekenaarprogram, Conjoint Value Analysis (CVA), Version 2.0 sisteem, verwerk. Hulle wys hulle voorkeure deur die toekenning van 'n rangorde van 'n aantal van verskillende kombinasies van eienskap-vlakke om nuttigheidswaardes vir die eienskappe te gee. Ses verteenwoordigende kampe (drie grates en drie kleintjies) is gebruik vir 'n gestratifiseerde steekproef van 428 respondente. Die bevindings sal aanbevelings gee wat gebruik kan word. / Dissertation (MCom)--University of Pretoria, 1999. / Marketing Management / MCom / Unrestricted

The first of a series of mass mortalities of Nile crocodiles in the Olifants and Letaba rivers in the Kruger National Park (KNP) was reported in the winter of 2008. The present study investigated the levels and possible effects on eggshell thickness of inorganic elements and organic pollutants in Nile crocodile eggs from these rivers, and comparing them with eggs from a reference crocodile farm and a reference dam inside the KNP. The egg contents were analyzed for chlorinated organic compounds and brominated flame retardants. Eggshells and egg contents were analyzed for inorganic elements. The elemental concentrations in the eggshells and contents were low when compared with previous studies. The highest concentrations were found in the eggs from the reference crocodile farm. The eggs from the reference dam and the crocodile farm had thicker shells, and the eggs from the Olifants and Letaba rivers had thinner shells. Not all eggs in a female develop at the same rate, while eggshell formation presumably occurs at the same time for all eggs. As a result, the elemental profile of egg contents may differ between eggs of the same clutch, but less so for the shells. Weak or no associations were found between the elemental concentrations of the content and eggshells and eggshell thinning. A possible organic pollutant–induced eggshell thinning effect was found. The compounds found were not at levels that could have caused the mortalities, but may affect the sex ratios through endocrine disruption. Further studies are therefore required. / Thesis (M.Sc (Environmental Science))--North-West University, Potchefstroom Campus, 2011.

Afrikaans Deneys Reitz, die derde van president F.W. Reitz se vyf oorlewende seuns, is op 2 April 1882 te midde van die politieke en ekonomiese ontwaking van die Vrystaat in Bloemfontein gebore. Hy het op die ouderdom van 17 by die Boeremagte aangesluit en doen hier die ondervindinge op wat hy later in sy eerste boek, Commando: A Boer journal of the Boer war, weergee. Met die sluit van vrede weier hy om die eed van getrouheid teenoor Brittanje af te lê en wend hom na Madagaskar waar hy onder meer as ‘n transportryer werk. Hy keer in 1903, op aandrang van Isie Smuts, na Suid-Afrika terug, kwalifiseer as ‘n prokureur en open ‘n prokureurspraktyk in die Noordoos-Vrystaatse dorp Heilbron. Gedurende die 1914-rebellie skaar hy homself aan die Botha-Smuts regering se kant en voer hy die Heilbronkommando aan teen die rebelle. Tydens die Eerste Wêreldoorlog sluit hy hom aanvanklik by Botha en Smuts in Duits-Suidwes-Afrika aan en daarna by die Britse leër in Brittanje. Hy spandeer die meeste van die Eerste Wêreldoorlog in die loopgrawe aan die Wesfront in Frankryk en vorder tot die rang van kolonel in bevel van ‘n bataljon van die First Royal Scots Fusiliers. Met sy terugkeer na Suid-Afrika in 1920 wend hy hom tot die politiek en as lid van die Suid-Afrikaanse Party verteenwoordig hy eers Bloemfontein-Suid (1920) en later Port Elizabeth. Vanaf 1929 verteenwoordig hy Barberton. Hy dien aanvanklik in die parlement as Minister van Lande, waar hy onder meer betrokke raak by wetgewing i.v.m. die totstandkoming van die Krugerwildtuin. Hy dien ook as Minister van Lande in die koalisie kabinet van J.B.M. Hertzog (1933) en daarna as Minister van Landbou en Bosbou (1935), Minister van Mynwese (1938), Minister van Naturellesake (1939) en as adjunkpremier in Smuts se Oorlogskabinet (1939-1943). Vir die periode van 1924 tot 1933 dien hy as deel van die amptelike opposisie, terwyl hy hoofsaaklik as ‘n prokureur in Johannesburg werk. In dié periode het hy ook uitgebreide private- en sakereise na onder meer Noord- en Suid-Rhodesië, die Belgiese Kongo en die Kaokoveld in Suidwes-Afrika onderneem. Sy bekendheid het hy grootliks verwerf uit die publikasie van sy herinneringe van die Anglo Boereoorlog, gepubliseer as Commando in 1929. Dit is erken as ‘n boek van uitstaande gehalte en word beskou as ‘n klassieke werk oor die Anglo-Boereoorlog. Die res van sy lewe, vanaf 1902 tot 1940, het hy in die boeke Trekking on en No outspan beskryf. Deneys Reitz was getroud met Leila Agnes Buissine Reitz (13/12/1887 – 29/12/1959). Sy was Suid-Afrika se eerste vroulike parlementslid en het Parktown verteenwoordig. Leila was veral by maatskaplike werk betrokke en het spesifiek op kinders en kindermisdadigers gefokus. Deneys en Leila het twee seuns gehad - Jan en Michael. Weens swak gesondheid word Reitz in 1943 as Hoë Kommissaris in Londen aangestel, waar hy in 1944 sterf. English Deneys Reitz, the third of president F.W. Reitz’s five living sons, was born in Bloemfontein on 2 April 1882 during the political and economical awakening of the Orange Free State. As a boy of seventeen he joined the Boer forces in the Anglo-Boer War, gaining the experience he set down in his first book, Commando: A Boer journal of the Boer war. After the peace he was an irreconcilable and lived as a transport rider in Madagascar, returning to South Africa in 1903 after prompting by Isie Smuts. He qualified as an attorney and practiced in the town of Heilbron in the north-east Free State. During the 1914 rebellion he commanded the Heilbron Commando against the rebels in support of the Botha-Smuts government. During World War I he first joined Botha and Smuts in German South West Africa and then in German East Africa, where after he enlisted with the British Army. He spent most of the First World War in the trenches in France, where he rose to command a battalion of the First Royal Scots Fusiliers. Upon his return to South Africa he entered Parliament in 1920 as a member of the South African Party, representing first Bloemfontein South (1920) and later Port Elizabeth. He represented Barberton from 1929. He initially held the portfolios of Lands (1923-24), becoming involved in developing legislation for the establishment of the Kruger National Park. He also served as Minister of Lands in the coalition government of J.B.M. Hertzog (1933), Minister of Agriculture and Forestry (1935), Minister of Mines (1938), Minister of Native Affairs (1939) and as deputy premier in Smuts’ War Cabinet (1939-1943). Reitz was a member of the formal opposition from 1924 to 1933, while also working as an attorney in Johannesburg. In this period he travelled extensively in both his private and official capacities to North and South Rhodesia, the Belgian Congo and the Kaokoveld in South West Africa. His real claim to fame, however, arises from his memoirs of the Anglo-Boer War, which he published under the title of Commando in 1929. This was immediately recognised as a work of outstanding quality and has become a South African classic on the Anglo Boer War. Later he wrote Trekking on and No outspan, continuing the story of his career. Deneys Reitz was married to Leila Agnes Buissine Reitz (13/12/1887 – 29/12/1959), the first South African women elected to parliament. She was member for Parktown. Leila, who was involved in welfare work, focused on children and delinquents. Deneys and Leila had two sons of their own - Jan en Michael. Due to ill health Reitz was appointed Union High Commissioner in London in 1943, where he later passed away. / Thesis (DPhil)--University of Pretoria, 2009. / Historical and Heritage Studies / unrestricted
