A spending behaviour model for selected South African arts festivals / Veronique Labuschagne

Labuschagne, Veronique January 2014 (has links)
Arts festivals form a large part of the South African culture originally as many local communities began to share their culture with visitors by means of arts festivals. This has grown into a large industry that has tremendous financial gain for the hosting communities. With over 500 arts festivals each year in South Africa alone, visitors are certain to find a festival to satisfy their specific needs and wants. Therefore, with so many genres available, each festival has created its own niche market and loyal customer base. An extensive literature study was conducted for the purpose of this thesis and it was found that research of small to medium arts festivals has been neglected. This finding motivated the main theme of this research. As mentioned earlier, there are so many genres available that the festival organisers may experience difficulty when deciding what to offer and how many genres to offer in order to still be sustainable and attract a sufficient number of visitors. Furthermore, the large number of arts festivals organised each year makes it increasingly difficult for festivals to build a loyal client base. First-time visitors can be converted into repeat visitors if the marketing strategy is precise. Repeat visitors, as stated in the literature, results in a sustainable income for each festival. Another question that motivated the research was the location of the three arts festivals (Innibos, Vryfees, and Kierieklapper). Three arts festivals in three provinces makes an interesting study to determine whether there is a difference in the three types of visitors that they attract and the spending patterns at each festival. While addressing the problems stated above, this study produced the following three articles: * Article 1: ―Determinants of spending at Vryfees with a focus on genres‖. * Article 2: ―First-time versus repeat visitors at Innibos Arts Festival‖. * Article 3: ―Role of location in the attendance and spending of festinos‖. Article 1 investigates spending determinants that influence visitor expenditure on the different genres offered at the Vryfees Festival in Bloemfontein, based on a survey conducted in 2011. The research is based on the notion that different genres have different spending patterns. Article 2 focuses on the differences and/or similarities between first-time and repeat visitors at the Innibos Arts Festival as an alternative approach to market segmentation. Lastly, the third article focuses on three different arts festivals in three different locations in South Africa. The research was conducted by means of a visitor survey at the three arts festivals during the same year with questionnaires administered at Innibos (428), Vryfees (336), and Kierieklapper (202) respectively. The most significant contributions of this study can be summarised as follows: * the tourist spending behaviour in regards to the difference between first-time and repeat visitors is significant and can be considered an important spending determinant; * the tourist spending behaviour in terms of length of stay between first-time visitors and repeat visitors is significantly different, suggesting that familiarity with the destination (as the repeat visitors are) has an important impact; * different locations attract their own type of tourists and certain locations receive a higher economic injection than other provinces do because of the type of festival held. All three arts festivals attract mainly Afrikaans speaking attendees; and for the first time, a comparative study has been conducted on three arts festivals targeting the Afrikaans speaking community. Additionally, this is the first time a comparative study was conducted on three small to medium arts festivals located in three different provinces; and * the developed spending model described in the last chapter of this thesis can assist the festival organisers with future festival marketing to improve their income and marketing strategy. / PhD (Tourism Management), North-West University, Potchefstroom Campus, 2014

No. of bitstreams: 1 Maria Cecilia de Vilhena Moraes Silva.pdf: 1246481 bytes, checksum: b36c2aeff72f55fcdd6467b0a7b3dc27 (MD5) Previous issue date: 2010-06-16 / Since they were created, psychological tests have been used in different contexts to support decisions that affect the life of many people. If they are to be used properly, it is critical to know both their underlying theoretical assumptions and their limitations. This thesis aims to bring to light such assumptions and to demonstrate that psychological tests , as a generic label, is not suited for the broad array of psychological assessment techniques available today. Based on the work of Pierre Bourdieu, who considers scientific knowledge as a social activity and the conformation of scientific fields as stemming from the configuration of the forces that conform it in a given historical period, this thesis investigates the trajectory of Alfred Binet and Francis Galton, two important actors of the psychological assessment field, considering the personal, social and historical context of their work, and the influence of their contributions to the subsequent conformation of this field. The differences between projective techniques and psychometrical tests are highlighted and the implications of considering both as psychological tests for the conformation of the psychological assessment field in Brazil, today, are discussed. A few issues regarding the education of qualified psychologists for the proper use of these techniques are also considered / Desde sua criação, os testes psicológicos têm sido usados em diferentes contextos, subsidiando decisões que afetam a vida de muitas pessoas. Seu uso adequado tem, como condição fundamental, o conhecimento de seus pressupostos teóricos e de suas limitações. O objetivo deste trabalho é explicitar tais pressupostos e demonstrar que o rótulo genérico testes psicológicos é inadequado para abrigar a diversidade de instrumentos do exame psicológico existentes. Com base em Pierre Bourdieu, considera-se o conhecimento científico como uma atividade social, sendo a conformação de um campo científico decorrente da configuração das forças que o compõem e de seus respectivos pesos em um dado momento histórico. Procura-se recuperar a trajetória de Alfred Binet e de Francis Galton, dois dos principais atores do campo do exame psicológico, abordando o contexto pessoal, social e histórico em que desenvolveram suas obras, e a influência de suas ideias na conformação posterior do campo. A partir disso, procura-se diferenciar técnicas projetivas e testes psicométricos, discutir as implicações de considerá-los sob o mesmo rótulo na conformação do campo do exame psicológico no Brasil de hoje e apontar aspectos importantes da formação do psicólogo para o uso adequado desses instrumentos

Agencies responsible for environmental protection, in most of the cases, only publish the final versions of the regulatory measures adopted, without further details on supporting, technical justifications, alternatives considered and possible contributions from social participation, among other issues. As a consequence, the environmental management faces accountability issues. To overcome this scenario, the regulatory impact analysis is presented as an instrument able to add clarity, objectivity and efficiency to environmental decision making. The incorporation of the tool, however, should be performed with particular caution, in view of three major peculiarities of Environmental Law. Firstly, the sector not only handles with risk, but also with uncertainty, in which due to the absence of information, it is impossible to make probability calculation about possible outcomes. Secondly, environmental regulation deals with non-tradable assets to which traditional cost-benefit analysis is not easily applicable. Finally, the environmental regulatory authority is shared by various agencies at all levels of government, increasing the odds of technical failures. / A regulação ambiental carece de maior transparência. Os órgãos de proteção do meio ambiente, em regra, apenas publicam as versões finais das medidas elaboradas, sem explicitar as justificativas técnicas que as embasaram, as alternativas consideradas e as possíveis contribuições decorrentes de participação social, entre outras questões. Em consequência, tem-se um cenário desfavorável à realização de controle pelos mais diversos atores. Para superá-lo, a análise de impacto regulatório é apresentada como instrumento apto a agregar clareza, objetividade e eficiência ao processo decisório ambiental. A incorporação da ferramenta, no entanto, deve ser realizada com cuidado especial, tendo em vista a existência de três principais peculiaridades do direito do meio ambiente. Primeiro, o setor lida não só com situações de risco, mas também com casos de incerteza, em que a ausência de informação impossibilita o cálculo de probabilidade de ocorrência de possíveis resultados. Em segundo lugar, a regulação ambiental recai sobre bens não transacionados em mercados, o que dificulta a obtenção de seu valor de troca, aspecto relevante para a análise de custo-benefício como tradicionalmente conhecida. Por fim, o meio ambiente apresenta desenho regulatório absolutamente fragmentado, composto por variados órgãos normatizadores, deliberativos e fiscalizadores em todos os níveis da federação, o que eleva o risco de deficiências na formação técnica das autoridades reguladoras.

Neurotrophin Receptor p75NTR Regulates Immune Function of Plasmacytoid Dendritic Cells

Bandoła, Joanna, Richter, Cornelia, Ryser, Martin, Jamal, Arshad, Ashton, Michelle P., von Bonin, Malte, Kuhn, Matthias, Dorschner, Benjamin, Alexopoulou, Dimitra, Navratiel, Katrin, Roeder, Ingo, Dahl, Andreas, Hedrich, Christian M., Bonifacio, Ezio, Brenner, Sebastian, Thieme, Sebastian 06 December 2017 (has links) (PDF)
Plasmacytoid dendritic cells (pDCs) regulate innate and adaptive immunity. Neurotrophins and their receptors control the function of neuronal tissue. In addition, they have been demonstrated to be part of the immune response but little is known about the effector immune cells involved. We report, for the first time, the expression and immune-regulatory function of the low affinity neurotrophin receptor p75 neurotrophin receptor (p75NTR) by the antigen-presenting pDCs, mediated by toll-like receptor (TLR) 9 activation and differential phosphorylation of interferon regulatory factor 3 and 7. The modulation of p75NTR on pDCs significantly influences disease progression of asthma in an ovalbumin-induced mouse model mediated by the TLR9 signaling pathway. p75NTR activation of pDCs from patients with asthma increased allergen-specific T cell proliferation and cytokine secretion in nerve growth factor concentration-dependent manner. Further, p75NTR activation of pDCs delayed the onset of autoimmune diabetes in RIP-CD80GP mice and aggravated graft-versus-host disease in a xenotransplantation model. Thus, p75NTR signaling on pDCs constitutes a new and critical mechanism connecting neurotrophin signaling and immune response regulation with great therapeutic potential for a variety of immune disorders.

Accounting for Domain Names based on German Commercial Code (HGB) and IFRS / Účtování internetových domén na zákldě německého Obchodního zakoníku (HGB) a IFRS

Schneider, Florian January 2010 (has links)
The goal of this dissertation was to conduct an analysis of domain name accounting according to HGB and IFRS, based on generic, qualified and personal domain names and in consideration of the effect of the relationship to brands and websites as related assets on their recognition, measurement and presentation in the balance sheet. In this regard, the focus of interest lied in clarifying the differences and similarities in domain name accounting, between the rather creditor-oriented HGB and the more capital market-oriented IFRS, between the major types of domain names and between theory and practice.
