The thesis deals with the topic of the congress tourism in the European Union and based on the analysis of its current status it evaluates the potential, shortcomings and opportunities for the development of congress tourism in the EU in the future. The thesis is focused on the comparison of the situation in the European Union and the United States of America especially from the point of view of the organisational background, financial issues and the number of realised events per year. The emphasis is put on the supranational/federal level which is mixed with the examples of the lower levels in order to capture the discussed topics in practise.

In 1993, the Asia-Pacific Economic Cooperation forum (APEC) held the first APEC Economic Leaders Meeting (AELM). Raising APEC interaction to the top track, the level of leaders, proved to be an effective and powerful dynamic; the AELM continues to meet annually and to shape APEC policy. The focus on the AELM as the source of vision and direction reinforces the pivotal importance of this political assemblage, reassures the populace that leaders do prevail and all is well: essential ingredients, according to Clifford Geertz, of political theater. The role of journalists, the contemporary scribes or critics, is to inform the audience of this political drama. The objective of this research is to demonstrate that real political value exists in the 'Staging of APEC' in terms of effective economic and political integration of benefit to broad regional interests. The findings draw on the results of a content analysis of news reports covering the first six years of the AELM (1993-1998). Formally, the AELM is an opportunity for regional political leaders to engage in regional policy formation outlined by the pillars of APEC (trade liberalization, facilitation and cooperation) guided by the principals of open regionalism and concerted unilateralism. Activity on the formal, or main stage, also flows to the small stage where leaders merge in a neutral venue. On this stage, leaders are free to examine distinctly non-economic, yet intersecting interests including domestic agendas, human rights and pluri-lateral security concerns. Together, these dual stages, neither one complete without the other, form the political theatre of APEC and provide the value added for the leaders and ultimately for the Asia – Pacific region. / Arts, Faculty of / Asian Research, Institute of / Graduate

Submitted in partial compliance with the requirements for the Master’s Degree in Technology: Chiropractic, Department of Chiropractic and Somatology, Durban University of Technology, Durban, South Africa, 2016. / Background Chiropractic is practiced in over 100 countries and is considered to be the fastest growing health care profession internationally. Several studies investigating the practice characteristics of chiropractors have been conducted in selected countries, however, as far as is known, no study has been conducted where chiropractors from countries across the globe are assessed for their practice characteristics in order to determine if regional differences exist. Gaining insight into chiropractic practice and its influencing factors, relating to both the profession itself and the chiropractor can enable organisations such as the World Federation of Chiropractic to have a greater understanding of how chiropractors are currently practicing and how the profession is being utilised by the public. Improved insight into the profession provides a baseline description for the public and other health care practitioners to fully comprehend what chiropractors can offer to the health care system. Aim: The aim of this study was to determine the demographic profile and practice characteristics of chiropractic delegates attending the World Federation of Chiropractic’s 12th Biennial Congress 2013. Method A pre-validated questionnaire and letter of information and consent was distributed to all registered chiropractic delegates (N = 406) attending the World Federation of Chiropractic Congress in Durban, Kwa-Zulu Natal 2013. The questionnaire was part of the delegate packages and they self-selected to participate. Due to a low response rate at the congress, the questionnaire was made available electronically on Survey Monkey®, for six weeks after the congress. Questions relevant to this study were coded, reduced where necessary and utilised for data analysis with IBM SPSS Version 21. Descriptive data was then summarised and presented using tables and graphs. The study was approved by the Durban University of Technology’s Institutional Research Ethics committee. Results: The response rate was 34.72%, with 52.5% being female, mean age was 42 (SD ± 13years, and all seven geographical regions were represented. The majority of respondents were from Africa (51.1%), followed by North America (22.7%) then Europe (14.2%). South Africa (48.6%) was the most represented country. Respondents held either a Master’s degree in Chiropractic (51.8%) or a Doctor of Chiropractic (DC) degree (48.2%). The mean years since graduating as a chiropractor was 15.7 years (SD ± 3.6). The majority of respondents (71.2%) engaged in full-time clinical practice, for between 5 to 15 years (39.8%) with 51.4% purporting to have an evidence based philosophical approach to practice. The majority (72.5%) viewed the role of a chiropractor in the health care system as a primary health care practitioner with a focused scope of practice. The majority of respondents (n = 52) personally treated 50 patients or less per week, with approximately one third of the respondents (n = 34) having high volume practices (>100 patients weekly). The respondents favoured being one of two chiropractors (36.9%) in a practice setting followed by sole practices (31.6%). The top chiropractic technique utilised was the diversified technique (74.5%) followed by extremity adjusting (68.8%). Various adjunctive, active and passive, axillary techniques were utilised in the daily management of patients. The patient demographics were majority female (55.7%), older than 30 years of age (66.7%) and Caucasian (77%), complaining of head, neck, mid-back and low back pain, which was mostly acute in nature. Trends suggested that females were more likely to select an evidence-based philosophical orientation than males. Females were more likely to delegate adjunctive therapies to non-chiropractic assistants (p = 0.029), and favoured sending patients to a physical therapist (p = 0.018), whereas males were more likely to refer to nutritionists and paediatricians (p = 0.030 and p = 0.038, respectively). Females were less likely to utilise mobilisation techniques (p = 0.008), massage therapy (p = 0.018) and nutritional counselling (p = 0.032). In terms of age, those selecting an evidence-based approach were significantly older than those who adopted a mixer approach to practicing (p = 0.002). The mean age of the respondents, irrespective of the region, was not significantly associated with the number of patients treated per week (p = 0.377) or the hours worked per week (p = 0.474). Trends show that the number of years spent in practice differed among the regions with North American chiropractors spending more years in practice than those from Europe and Australasia. The respondents from South Africa spent fewer years in practice (15 years or less) than respondents from Asia, Australasia, Europe and North America. Geographic region was not significantly associated with practice setting (p = 0.182). The only chief complaint that differed between regions was patients presenting with headaches accompanied by neck pain (p = 0.007), where Asian and North American respondents reported seeing less patients than their colleagues from other regions. Trends suggested that the respondents who attained a Masters of Technology in Chiropractic were more inclined to select a mixer orientation whereas those with a DC qualification selected an evidence-based philosophical approach. Conclusion: The WFC congress provided a platform to successfully determine the demographic profile and practice characteristics of chiropractors from various regions. Similar demographics were evident, with males no longer showing dominance within the profession. Chiropractors adopting an evidence-based and mixer philosophical orientation are synonymous in the role that they play in the health care system and display similarities in chiropractic practice and patient management. Investigating chiropractors who adopt a straight philosophical approach would be beneficial as it will allow for better comparison of demographics and practice characteristics. It is evident that selected demographics do influence how one would opt to practice, with regional differences showing that the chiropractic profession in South Africa is still relatively young. / M

This research is a replication of part of Dr. Catherine Price's dissertation study "An Empirical Study of Professional Association Meetings from the Perspective of Attendees" (1993). The paper presented is a research study in the area of meeting/conference attendee preferences. This research tested which attributes of meeting selection were of importance to a particular population. Dr. Price (1993) identified four variables as important attributes for attendees in their selection of a meeting. They were: a) education, b) leadership, c) networking, and d) professional savvy. The primary hypothesis was directed at confirming the validity of these attributes. Four factors emerged in the analysis of this study. Three factors were identical to the Price (1993) study. These factors were: a) education, b) leadership, and c) networking. The fourth factor that emerged was named potpourri. Ultimately, this study attempted to be significant in assisting meeting planners in the preparation of more effective meetings. / Master of Science

The problem of finding a reduced order model, optimal in the H² sense, to a given system model is a fundamental one in control system analysis and design. The addition of a H^∞ constraint to the H² optimal model reduction problem results in a more practical yet computationally more difficult problem. Without the global convergence of homotopy methods, both the H² optimal and the combined H²/H^∞ model reduction problems are very difficult. For both problems homotopy algorithms based on several formulations input normal form; Ly, Bryson, and Cannon's 2 X 2 block parametrization; a new nonminimal parametrization are developed and compared here. For the H² optimal model order reduction problem, these numerical algorithms are also compared with that based on Hyland and Bernstein's optimal projection equations. Both the input normal form and Ly form are very efficient compared to the over parametrization formulation and the optimal projection equations approach, since they utilize the minimal number of possible degrees of freedom. However, they can fail to exist or be very ill conditioned. The conditions under which the input normal form and the Ly form become ill conditioned are examined. The over-parametrization formulation solves the ill conditioning issue, and usually is more efficient than the approach based on solving the optimal projection equations for the H² optimal model reduction problem. However, the over-parametrization formulation introduces a very high order singularity at the solution, and it is doubtful whether this singularity can be overcome by using interpolation or other existing methods. / Master of Science

This is a study of business education conferences in Texas made in an effort to improve business training in Texas secondary schools. Many young people leave high school intending to enter the business world. Business is ready to accept those who are competent. The educational preparation of students, however, is often insufficient to permit their seizing the opportunities offered to them.

This thesis begins by providing an account of the ancestral grave relocations of the Sekuruwe community in Limpopo province, South Africa. Sekuruwe claims that the manner in which their graves were relocated disrespected their cultural norms, and infringed their constitutional rights. Over three years of investigation, it was proved that the mine which relocated the graves acted negligently by badly damaging human remains, confusing graves and loosing skeletons. The thesis investigates Sekuruwe‟s case within three theoretical frameworks: Systemic oppression, legal claims to culture, and Ethnicity Incorporated. The role of heritage legislation is highlighted throughout the thesis, and the inadequacies of legislation pointed out with reference to the different theoretical approaches. The aim of the thesis is to understand the way in which Sekuruwe‟s claims of cultural insensitivity are in fact claims of injustice, which are argued through the bodies (and graves, and spirits) of the dead. I aim to understand the way in which these claims of injustice are structured by heritage legislation.

This study describes young writers' conferences in school districts in the state of Texas. The study proposed: (a) to describe the characteristics of young writers' conferences; (b) to determine how young writers' conferences were created and implemented; (c) to identify the purpose of writing conferences; (d) to identify the population served; (e) to describe the unique contribution of conferences; (e) to determine the perceived value of conferences to school district personnel. A 26 item survey was developed and distributed to 133 Texas school districts. One hundred percent of the districts responded to the survey or telephone interview Data was collected from the ten districts that provided young writers' conferences for young writers during the 1994-95 school year. Eighty percent of the school administrators surveyed rated their program as very beneficial for young writers. Twenty percent rated their program at the second highest rating, or beneficial. All of the districts reported that as a result of the workshop, writing has become more important in the districts. In addition, the majority of the districts reported that parents are more aware of the importance of writing and that teacher attitudes toward writing have improved as a result of participation in the workshop Districts also reported that students have a more positive attitude toward writing and are more interested in writing after having attended the workshop. It can be concluded from the study that students in grades nine through twelve were largely undeserved by the districts in the sample. Therefore, the researcher suggests that districts serve this population in future conferences. The researcher also recommends that a democratic process be established that would maximize the number of participants attending young writers' conferences in each district. Information obtained from the study can inform educational policy makers, educators, parents and citizens about young writers' conferences and can also serve as a resource for conference planners and participants as similar programs for young writers are created, implemented and evaluated.

Thesis (M.Sc. (Microbiology)) -- University of Limpopo, 2018 / Beer is one of the most widely consumed alcoholic beverages in the world. The brewing process is based on natural enzymatic activities that take place during the malting of barley grain, mashing of grist and fermentation of wort. Insufficient malt enzyme activity during the mashing process leads to high levels of barley β-glucan, arabinoxylan (AX) and dextrins in the wort as well as in the final beer. It was reported that high levels of β-glucan and AX increase wort and beer viscosity which lower the rate of beer filtration and this negatively affect the production rate in the brewery. During beer fermentation, brewing yeast catalyses the conversion of wort sugars to ethanol, carbon dioxide and other metabolic products. However, non-fermentable carbohydrates i.e., limit dextrins remain in the wort and final beer. These non-fermentable carbohydrates are known to contribute to the caloric value of beer which might lead to weight gain in consumers. The objectives of this study were to evaluate the effect of recombinant yeast strains expressing an endo-β-1,4-glucanase or an endo-β-1,4-xylanase on beer viscosity (as an indicator of filterability) and an α-amylase on residual sugars levels. The effect of the above mentioned enzymes on the aroma, appearance, flavour, mouth-feel and overall quality of the beer was also determined. Wort was produced in the University of Limpopo micro-brewery and the wort was pitched with different recombinant strains. The wild-type strain served as control. The results obtained showed that the xylanase expressing strain produced a measurable decrease in viscosity over the course of the fermentation, but endo-glucanase did not have any effect on the beer viscosity. The α-amylase producing strain, did not show a measurable reduction of residual sugars in the final beer probably as a result of very low activity on α-1,6 glycosidic bonds in dextrins during fermentation. The xylanase and α-amylase producing strain fermented effectively with good attenuation (decrease in wort specific gravity). The beer produced by the α-amylase and control strains were preferred in terms of taste and had similar qualities. The secreted amylolytic activity was not sufficient to significantly reduce residual sugar in the final beer. Although the xylanase secreting strain produced a beer with lower viscosity, the enzyme had a negative impact on the taste of the beer. Key words: Brewer’s yeast, beer fermentation, low calorie beer, amylase, xylanase, endo-glucanase.
