Thesis (MA)--Stellenbosch University, 2000. / ENGLISH ABSTRACT: European cities offer a variety of attractions, activities and facilities to tourists. One component of tourism in this urban context is cultural tourism which is a high potential growth sector within the tourism industry. Cultural tourists travel to cities mainly to see the most important and well known cultural attractions, to take part in cultural festivities, to view the cultural treasures of the cities and to attend performances and exhibitions. Other functions and activities such as retail functions and types also occur in the vicinity of the important cultural attractions of a city. Amongst these activities and functions are shops, cafés and restaurants. In an area of a city where cultural attractions and retail types coexist, the possibility exits that a spatial relationship between cultural tourism and retailing may occur in the sense that the tourists who visit these attractions may support the retail establishments in the vicinity of cultural attractions. The city of Leuven in Belgium is a typical West European city with a variety of cultural tourist attractions as well as functions which can be supportive of cultural tourism. These functions include shops, cafés and restaurants. An investigation was conducted to establish whether a spatial relationship exists between cultural tourism and retail activities in the part of Leuven known as the Ring. The geographical information systems TransCad, Arc/Info en ArcView were used for the processing and analysis of retail and cultural tourism data gathered in the Ring of Leuven. Three analytical procedures were performed separately for shops, cafés and restaurants. These procedures comprised (a) the determination of the numbers and types of supportive functions around the most important cultural-historical tourist attractions, (b) the determination of the numbers and types of supportive functions along the routes to cultural-historical sites from tourist points of origin, and (c) the determination of the numbers and types of supportive functions along guided-walk routes in the city. The analysis results show that a (spatial) relationship does exist between retail and cultural tourism in the Ring of Leuven. On average 44% of the retail functions (shops, cafés and restaurants) are located within a distance of up to saam from the six most important cultural building attractions in Leuven (procedure 1). Retail functions on guided-walk routes totalled 48% with cafés and restaurants being the most abundant (procedure 3). Only 19% of retail functions are located between points of origin and cultural building attractions (procedure 2). A more detailed study should be conducted to establish the exact nature of the spatial relationship which exists between retail and cultural tourism in the Ring of Leuven. / AFRIKAANSE OPSOMMING: Europese stede bied 'n reeks attraksies, aktiwiteite en fasiliteite vir toeriste. Een komponent van die breër term toerisme in hierdie stedelike konteks is kulturele toerisme wat 'n baie sterk groeisektor binne die toerismemark is. Kulturele toeriste besoek stede hoofsaaklik met die doelom die belangrikste en bekendste kulturele attraksies te besigtig, om aan kulturele feeste deel te neem, die kunsskatte van stede te betrag en om teateropvoerings en tentoonstellings by te woon. In die nabyheid van die belangrikste kulturele attraksies van 'n stad kom ook ander funksies en aktiwiteite soos kleinhandelsfunksies en -tipes voor. Hieronder ressorteer onder andere winkels, cafés en restaurante. In die gedeelte van 'n stad waar kulturele attraksies en kleinhandelstipes naby mekaar voorkom, kan die moontlikheid bestaan van 'n ruimtelike verwantskap tussen kulturele toerisme en kleinhandel, in dié sin dat toeriste wat die attraksies besoek, moontlik ook die kleinhandelstipes wat in die nabyheid van die kulturele attraksies voorkom, salondersteun. Die stad Leuven in België is 'n tipiese voorbeeld van 'n Wes-Europese stad met 'n verskeidenheid kulturele toeriste-attraksies asook funksies wat kulturele toerisme ondersteun. Hierdie ondersteunende funksies sluit winkels, cafés en restaurante in. In die deel van Leuven wat as die Ring bekend staan, is ondersoek ingestel na die voorkoms, al dan nie, van 'n ruimtelike verwantskap tussen kulturele toerisme en kleinhandel. Die geografiese inligtingstelsels TransCad, Arc/Info en ArcView is ingespan vir die verwerking en analise van data oor kleinhandel en kulturele toerisme in die Ring van Leuven. Drie ontledingsprosedures is afsonderlk uitgevoer vir winkels, cafés en restaurante. Hierdie prosedures behels (a) die bepaling van die aantal en tipes ondersteunende funksies rondom die belangrikste kultuurhistoriese toeristeattraksies; (b) die bepaling van die aantal en tipe ondersteunende funksies langs die roetes tussen die toeriste-oorsprongpunte en die belangrikste kultuurhistoriese toeriste-attraksies; en (c) die bepaling van die aantal en tipe ondersteunende funksies langs begeleide stadswandelroetes. Die analiseresultate wys dat 'n verwantskap tussen kleinhandel en kulturele toerisme, ruimtelik-gesproke, wel in die Ring van Leuven bestaan. Só is gemiddeld 44% van die kleinhandelsfunksies (winkels, cafés en restaurante) tot op In afstand van SOOmvanaf die ses belangrikste kulturele gebou-attraksies in Leuven geleë (prosedure 1). Ook kom 48% van die kleinhandelsfunksies langs die roetes van begeleide stadswandelinge voor. Hier is dit egter die cafés en restaurante wat die grootste proporsies uitmaak (prosedure 3). 'n Gemiddelde proporsie van slegs 19% van die kleinhandelsfunksies kom tussen oorsprongpunte en die belangrikste kulturele gebou-attraksies voor. 'n Meer omvattende studie moet onderneem word om vas te stel watter tipe ruimtelike verwantskap tussen kleinhandel en kulturele toerisme binne Leuven se Ring voorkom.

Les questions de l'usage de l'espace public sont devenues un sujet de recherche important dans le passé récent. La recherche plutôt opérative a mis en avant un ensemble convaincant de recommandations de dessin et de gestion pour améliorer l'usage des espaces, mas elle a à peine réussi à approcher la question comme un problème de politique et planification urbaines. Ce projet de recherche essaiera de contribuer pour le replacement du problème à une échelle urbaine, à travers la comparaison de trois processus de production de l'espace public à l'échelle urbaine, notamment Lyon, Louvain-la-Neuve et Lisbonne. Dans ces trois terrains, des différentes façons de prendre en compte l'usage ont été suivies et cette diversité fait partie de la problématique. Cette recherche adopte une approche inductive au sujet, cadrée par des lectures dans l'intersection de la sociologie de l'action et des études de politiques publiques, qui cherchent expliquer les résultats de l'action collective par des analyses approfondies de leurs processus. Cependant, elle maintient un repère géographique dans la mesure où elle est concernée aussi par la spatialisation des politiques publiques, c'est-à-dire les espaces produits par les différents processus et les dynamiques d'usage qu'y sont présentes / Issues of public space use have become a paramount subject of research in the recent past. While research of an overtly operative outlook has convincingly put forward design and management recommendations for improving the use of public spaces, it has struggled in approaching the issue as the scope of urban policy and planning. This research project aims at contributing to re-placing the problem at an urban scope. It will do so by comparing three very different policy and planning processes which, at an urban scale, explicitly put forward use as a main objective of public space production, namely Lyon, Louvain-la-Neuve and Lisbon. The diversity of what 'taking use into account' might mean in each case study is a part of the research problem. This research adopts an inductive approach to the subject, framed by readings in the intersection of pragmatic sociology, policy and economics/management studies which suggest the explanation of policy outcomes by in-depth analyses of the processes leading to them. However, it maintains a geographical standpoint as it is concerned, as well, with the “spatialization of public policies”, i.e. the spaces that are actually produced by said processes and the dynamics of use taking place therein

The field of Enterprise Architecture (EA) emerged as an answer to the increasing complexity in managing and aligning the business-IT relationship within enterprises. Both practitioners and academics have expressed interest in the field, with a growing number of publicized works related to EA. In an attempt to provide an outlook of the current research landscape of EA, a systematic literature review was conducted. Citation data from the Scopus (Elsevier) API were automatically extracted and analyzed. By applying the Louvain method on the collected data, 8 research communities and their topic were identified: (1) Enterprise Engineering (I & II), (2) Enterprise Architecture Management, (3) Enterprise Modelling, (4) IT Architecture, (5) Enterprise Integration, (6) Digital Transformation, and (7) Smart Cities. For each community, a summarized description with sub-community graphs as well as tables (describing the top authors, articles, and affiliation countries) are presented. Lastly, a comparison of the results and the EA trends identified by Gampfer et al. are presented. / Fältet Enterprise Architecture (EA) framkom som ett svar på den ökande komplexiteten i att hantera och anpassa affärs-IT-relationen inom företag. Både utövare och akademiker har uttryckt intresse för området, då antal publicerade verk relaterade till EA fortsätter att växa. I ett försök att ge en syn på det aktuella forskningslandskapet inom EA genomfördes ett systematisk litteraturöversikt. Citeringsdata från Scopus (Elsevier) API extraherades och analyserades automatiskt. Genom att tillämpa Louvain-metoden på insamlade datan identifierades 8 forskarsamhällen och deras ämnen: (1) Enterprise Engineering (I & II), (2) Enterprise Architecture Management, (3) Enterprise Modelling, (4) IT Architecture, (5) Enterprise Integration, (6) Digital Transformation och (7) Smart Cities. För varje gemenskap gavs en sammanfattad beskrivning med undergruppsdiagram samt tabeller (över t.ex. de främsta författarna, artiklarna, och anslutningsländerna). Slutligen så gjordes en jämförelse av resultaten och de EA trender som identifierats av Gampfer et al.

Big data is an area focused on storing, processing and visualizing huge amount of data. Today data is growing faster than ever before. We need to find the right tools and applications and build an environment that can help us to obtain valuable insights from the data. Retail is one of the domains that collects huge amount of transaction data everyday. Retailers need to understand their customer’s purchasing pattern and behavior in order to take better business decisions. Market basket analysis is a field in data mining, that is focused on discovering patterns in retail’s transaction data. Our goal is to find tools and applications that can be used by retailers to quickly understand their data and take better business decisions. Due to the amount and complexity of data, it is not possible to do such activities manually. We witness that trends change very quickly and retailers want to be quick in adapting the change and taking actions. This needs automation of processes and using algorithms that are efficient and fast. In our work, we mine transaction data by modeling the data as graphs. We use clustering algorithms to discover communities (clusters) in the data and then use the clusters for building a recommendation system that can recommend products to customers based on their buying behavior.
