Seu foco não é, entretanto, o aprofundamento de cada uma das etapas deste método (uma vez que existe uma ampla literatura sobre o assunto), mas realçar a importância do envolvimento do usuário aqui denominado consumidor da informação durante o processo de criação e manutenção destes data marts / data warehouses. O consumidor da informação é chamado a participar de um plano integrado com os membros das áreas detentoras do conhecimento necessário para a construção destas soluções de suporte à decisão, incluindo a área de tecnologia da informação. A disseminação das informações contidas nestes bancos de dados para os diversos tipos de consumidores da informação(com diferentes recursos de hardware, software e humanos disponíveis), e sua aplicação no controle social, também são discutidas aqui. / The purpose of this work is to present the required steps for the construction of data marts / data warehouses as a solution for a decision support environment. However, its focus is not to go deeper in each of the steps of this method (since there is a broad literature about the subject), but to highlight the importance of the user – here called information consumer – engagement during the process of creating and maintaining these data marts / data warehouses. The information consumer is called to take part in an integrated plan together with the members of the areas who own the necessary knowledge to build these decision support solutions, including the information technology (IT) area. The spread of the informations contained in these databases to the different types of information consumers (with different hardware, software and human resources available), and its application in social control, is also discussed here.

We compared two establishments in the city of Curitiba, Brazil: a national network and another pertaining to an offshore network. The assumption that edges the research is that, since this kind of supermarket displays the characteristic of non communication with external ambiances - unlike a local grocery store or a market place where the service is personalized and engaging - human relations in their environment are depthless, superficial or even nonexistent. In a society that tends towards the hybridization of typical composé of Latin American cities, in which the cultural blend is evident in urban areas, the understanding of how the supermarket network deals with this multiplicity and participates in several series to raise cultural leans towards expressive contrasts. The research is exploratory and explanatory, with empirical observation supported by photographic record. The theoretical and methodological framework is based on sources developed by Latour, Canevacci, Ferrara and Rennó, leading the analysis of urban culture from the point of view of the observation of the image. The concepts of fusion of culture and cultural studies, with the metaphors generated by the same provide the mechanisms of translational identified phenomena. The procedure of analysis is enriched by the contributions of Laplantine, Nous, Martín- Barbero, Gruzinski and Pinheiro. Another significant theoretical core under analysis was obtained in systems theory, with Vieira, Uexkull and Bunge. Urban space, center and periphery, mixed borders, consumer relations and the concept of non-place comes from the theoretical constructs of Certeau, Canevacci, Santos, Ferrara, Lotman, Delgado, Silva, Bauman, Underhill, Webber and Augé. The analysis of this study envisages the fact that the supermarket networks, domestic or offshore are not related to the individual as a customer, which is contradictory in societies that tend towards the hybridization of forms, such as Latin societies. At the national supermarket under analysis, were found embedded cultural series, but in an offshore network, these elements are not valued, as happens with the external aspects of local culture. Based on the systemic point of view and cultural studies, it can be said that these environments present themselves as non-places / Este trabalho tem como objetivo estudar, do ponto de vista de linguagem, o modo como os supermercados de rede estabelecem relações e se comunicam com o ambiente que os circunda, na atmosfera de uma sociedade mestiça. São comparados dois estabelecimentos na cidade de Curitiba-PR: um de rede nacional e outro de rede estrangeira. O pressuposto que norteia a investigação é o de que, em virtude de esse gênero de supermercado apresentar a característica de não se comunicar com o lado de fora diferentemente de uma mercearia de bairro ou um mercado municipal, em que o atendimento é personalizado e envolvente , as relações humanas em seu ambiente são despersonificadas, superficiais ou mesmo inexistentes. Em uma sociedade que tende à hibridização de formas típica das cidades latino-americanas, nas quais a mestiçagem cultural é manifesta nos espaços urbanos, a compreensão de como o supermercado de rede lida com essa multiplicidade e participa de várias séries culturais permite levantar contrastes expressivos. A pesquisa é de natureza exploratória e explicativa, com observação empírica sustentada no registro fotográfico. A fundamentação teóricometodológica tem base em fontes desenvolvidas por Latour, Canevacci, Ferrara e Rennó, que conduzem a análise da cultura urbana sob o ponto de vista da observação da imagem. Os conceitos de mestiçagem da cultura e os estudos culturalistas, com as metáforas a que dão origem, oferecem os mecanismos tradutórios dos fenômenos identificados. O procedimento de análise é enriquecido com as contribuições de Laplantine, Nous, Martín-Barbero, Gruzinski e Pinheiro. Outro fulcro teórico expressivo nas análises foi obtido na teoria sistêmica, com Vieira, Uexkull e Bunge. Espaço urbano, centro e periferia, fronteiras mestiças, relações de consumo e o conceito de não-lugar provêm dos construtos teóricos de Certeau, Canevacci, Santos, Ferrara, Lotman, Delgado, Silva, Bauman, Underhill, Webber e Augé. As análises deste trabalho apontam para o fato de que as redes de supermercado, nacional ou estrangeira, não se relacionam com o sujeito cliente, o que é contraditório em sociedades que tendem à hibridização de formas, como as sociedades latinas. No supermercado nacional analisado, foram encontradas séries culturais incorporadas, mas, na rede estrangeira, esses elementos não são valorizados, e sim, aspectos externos à cultura local. Com base na visão sistêmica e em estudos culturalistas, pode-se afirmar que esses ambientes apresentam-se como não lugares

摘要 中國自1970年代末期經濟改革開放以來，經濟快速成長，導致2012年中國的GDP已經超過了8兆美元，成為繼美國之後的世界第二經濟大國。隨著經濟的成長，中國也逐漸由製造業為主的經濟體，朝向發展服務業和內需型產業轉變。中國人民所得增加，消費能力增強，近幾年量販業在中國蓬勃發展，相較之下臺灣量販店目前的展店速度與營收成長趨緩。 本研究以在兩岸都設有賣場的量販店業者潤泰集團大潤發及法商家樂福為研究對象，蒐集這兩家業者在臺灣和中國兩地的相關資料，以市場定位、經營理念、經營策略、以及經營績效等，深入整理與分析，再運用深度訪談，透過競爭策略五力分析及SWOT分析，探討量販店業者如何運用兩岸不同的市場及不同經營策略創造績效。研究結果顯示不論是五力分析或是SWOT分析，中國大潤發的競爭力最強。反之，在五力分析中台灣家樂福所受影響最大，其中尤其以購買者的議價能力、替代品或服務的威脅，以及現有廠商的競爭程度等方面所受影響較大。另一方面，在SWOT分析中，中國家樂福較居於劣勢，而所受的威脅也最強，主要原因為門市集客力弱及面臨租金成本提高的壓力。 關鍵字：大潤發、家樂福、經營策略、經營績效、五力分析 / Abstract Since its reform in late 1970s, China has experienced high economic growth. With GDP over 8 trillion USD, in 2012 China became the second largest economy ranked only behind the USA. Accompanying with such growth, China slowly transited from a manufacturing-based into a service and domestic-based economy. As the economic condition improves, people’s consumption power increases, which drives rapid growth of the hypermarket industry in China; and as contrast, the Taiwanese hypermarket industry is reaching a plateau during the same period of time. In this research, a comparative study is conducted with hypermarket industries in China and Taiwan. Taking Carrefour and RT-Mart chains, that operate on both sides of the Taiwan Strait, as samples, this study employs SWOT analysis and Michael Porter’s Five Forces Model to investigate the business strategy and performance differences. In particular, this study collects business data of said companies, including company’s vision, market position, business strategy, and operational performance, and the exploration was supplemented by in-depth interviews with the high-ranking staff members in the two companies. The findings suggest that RT-Mart China is the most competitive confirmed by both SWOT and Five Forces analyses while Carrefour Taiwan is impacted by the buyer bargain power and threat of substitutes and services. In addition, via SWOT analysis, it is found that Carrefour China is in a weak position since it is suffering from high rental costs and inability to gather customers. Keywords: RT-Mart, Carrefour, business strategy, business performance, Michael Porter’s five forces analysis

In South Africa various financial institutions and independent vendors have developed residential property valuation models to estimate the current value of historically traded properties. A natural extension to these models has been to develop historical property price indices. In this dissertation, three of the four approaches to developing property price indices will be examined. Through back–testing and other statistical methods, the most accurate and robust approach will be determined. The four major approaches available are the mean valuation per suburb, the median valuation per suburb, the repeat sales approach and hedonic regression. The mean valuation per suburb approach can be biased because of outliers in property prices. However, outliers in property prices will not influence the median valuation per suburb approach, but in cases where property values in a suburb have a skewed distribution, the valuation amount could be distorted. Neither of the above mentioned shortcomings influences the repeat sales or the hedonic regression approach. To follow the hedonic regression approach, the characteristics of the property need to be known. In South Africa, however, the available property data lacks detailed characteristics of traded properties. This dissertation will therefore focus on the first three methods. The repeat sales approach measures the growth in property prices by applying a generalized linear model to properties that have traded more than once. This approach is only possible if there is a representative amount of repeat sales able to fit a model. The focus of this project will be on the repeat sales approach, but all three the approaches discussed will be analysed to prove that the repeat sales approach is the most accurate in developing a property price index for properties in South Africa. / Thesis (M.Sc.

The retail industry is considered to be a very competitive industry in the United States since there are so many players in the almost saturated retail markets that provide similar products and services at similar price levels to customers. Market selection has been identified as an important strategy to differentiate a retailer in this competitive market. Therefore in this thesis, we describe a conceptual framework to evaluate retailers investment opportunities in dynamic, competitive retail markets. The objective is to describe a conceptual investment analysis framework to address the strategic aspects of a retailer s investment opportunity as well as the dynamic uncertainty of a retail market in a single framework. This conceptual framework outlines a strategic view towards retail stores as flexible assets of a retail enterprise. This conceptual framework is general and can be adjusted and applied to investments options in other services. In addition, we develop an integrated investment analysis approach based on dynamic programming to explore retailers investment behaviors in dynamic markets. The objective is to determine retailers optimal investment thresholds in noncompetitive and competitive markets. We consider two retailers to illustrate our approach and use a simple game theory treatment to address competition in retail markets. We use our integrated investment analysis model based on a real options methodology to evaluate the apparent tendency for the small discount retailer invests earlier in a new developing market due to the competition effect from the large discount retailer. This early entry gives the small retail a first-mover advantage and delays the big retailer s entry into the competitive market. In addition, we conduct sensitivity analysis to characterize how significantly the values of our model parameters impact the retailers investment decisions. We also develop an integrated investment analysis approach based on contingent claims analysis to explore retailers investment behaviors in dynamic markets. The objective is to determine retailers optimal investment thresholds in noncompetitive and competitive markets. The equivalent risk neutral evaluation approach is presented in this thesis as an extended version of the contingent claims analysis approach, which facilitates the market-oriented valuation of the retailer s investment option in dynamic markets. Sensitivity analysis is conducted to study how retailers optimal investment thresholds change as the values of parameters in this equivalent risk neutral evaluation approach change. The relationship between the dynamic programming and the equivalent risk neutral evaluation approach is also summarized in this thesis to identify the similarities and the differences between these two investment analysis approaches. One of the most important objectives of this comparison is to determine in what market conditions the choice of investment analysis approach is critical and dramatically changes the retailer s optimal investment threshold. Finally, we empirically examine an important aspect of our theoretical work that the big retailer invests and opens a store relatively later in markets with a small retailer compared to markets without a small retailer. In addition, the big retailer opens a store at relatively higher retail market potential in markets with a small retailer compared to markets without a small retailer. In this thesis, we discuss some empirical evidence to support these theoretical results. We chose Wal-Mart and Dollar General as the big and small retailers, respectively, in our empirical study. Our empirical results do not validate the theory and just provide supporting evidence for our theoretical works.

Customer knowledge plays a vital part in organisations today, particularly in sales and marketing processes, where customers can either be channel partners or final consumers. Managing customer data and/or information across business units, departments, and functions is vital. Frequently, channel partners gather and capture data about downstream customers and consumers that organisations further upstream in the channel require to be incorporated into their information systems in order to allow for management information delivery to their users. In this study, the focus is placed on manufacturing organisations using third party distribution since the flow of information between channel partner organisations in a supply chain (in contrast to the flow of products) provides an important link between organisations and increasingly represents a source of competitive advantage in the marketplace. The purpose of this study is to determine whether there is a significant difference in the use of sales and marketing data marts as management information delivery mechanisms in manufacturing organisations in different industries, particularly the pharmaceuticals and branded consumer products. The case studies presented in this dissertation indicates that there are significant differences between the use of sales and marketing data marts in different manufacturing industries, which can be ascribed to the industry, both directly and indirectly. / Thesis (MIS(Information Science))--University of Pretoria, 2002. / Information Science / MIS / unrestricted
