The right to information privacy is considered a basic human right in countries that recognise the right to privacy. South Africa, and other countries that recognise this right, offer individuals legal protections for their information privacy. Individuals, organisations and even governments in these countries often have an obligation under such laws to protect information privacy. Large organisations, for example, multinational companies and government departments are of special concern when it comes to protecting information privacy as they often hold substantial amounts of information about many individuals. The protection of information privacy, therefore, has become ever more significant as technological advances enable information privacy to be breached with increasing ease. There is, however, little research on holistic approaches to protecting information privacy in large organisations. Holistic approaches take account of both technical and non-technical factors that affect information privacy. Nontechnical factors may include the management of information privacy protection measures and other factors such as manual business processes and organisational policies. Amongst the protections that can be used by large organisations to protect information privacy is the ability to investigate incidents involving information privacy. Since large organisations typically make extensive use of information technology to store or process information, such investigations are likely to involve digital forensics. Digital forensic investigations require a certain amount of preparedness or readiness for investigations to be executed in an optimal fashion. The available literature on digital forensics and digital forensic readiness (DFR), unfortunately, does not specifically deal with the protection of information privacy, which has requirements over and above typical digital forensic investigations that are more concerned with information security breaches. The aim of this thesis, therefore, is to address the lack of research into DFR with regard to information privacy incidents. It adopts a holistic approach to DFR since many of the necessary measures are non-technical. There is, thus, an increased focus on management as opposed to specific technical issues. In addressing the lack of research into information privacy-specific DFR, the thesis provides large organisations with knowledge to better conduct digital forensic investigations into information privacy incidents. Hence, it allows for increased information privacy protection in large organisations because investigations may reveal the causes of information privacy breaches. Such breaches may then be prevented in future. The ability to conduct effective investigations also has a deterrent effect that may dissuade attempts at breaching information privacy. This thesis addresses the lack of research into information privacy-specific DFR by presenting a framework that allows large organisations to develop a digital forensic readiness capability for information privacy incidents. The framework is an idealistic representation of measures that can be taken to develop such a capability. In reality, large organisations operate within cost constraints. We therefore also contribute by showing how a cost management methodology known as time-driven activity-based costing can be used to determine the cost of DFR measures. Organisations are then able to make cost versus risk decisions when deciding which measures in the framework they wish to implement. Lastly, we introduce the concept of a digital forensics management system. The management of DFR in a large organisation can be a difficult task prone to error as it involves coordinating resources across multiple departments and organisational functions. The concept of the digital forensics management system proposed here allows management to better manage DFR by providing a central system from which information is available and control is possible. We develop an architecture for such a system and validate the architecture through a proof-of-concept prototype. / Thesis (PhD)--University of Pretoria, 2012. / Computer Science / unrestricted

Detta examensarbete är en studie i hur en kontorsmiljö i form utav fyra stycken cellkontor och ett konferensrum kan utformas för en myndighet. Med syfte att skapa ett gestaltningsförslag som visualiserar möjliga lösningar för kontorets arbetsgrupp, för att sedan utformas till en aktivitetsbaserad kontorsmiljö som ska stödja arbetsgruppens behov och arbetssätt. Samarbetet har varit tillsammans med Näringslivsenheten i Stadshuset, Eskilstuna. Arbetsgruppen på Näringslivsenheten upplever att de vill vara mer integrerade med varandra då det är en stor del av deras arbetssätt. Väggarna, som cellkontoren innebär, skapar barriärer mellan användarna och medför en påverkan av deras arbetssätt. Lokalerna som verksamheten befinner sig i saknar även en identitet som speglar verksamhetens arbete och värden. Studien baseras på teori och litteratur om den rumsliga miljön, aktivitetsbaserat kontor, zoner i kontorsmiljön, kognitivt perspektiv, affordans, färg, ljus och kreativitetens betydelse i kontorsmiljön. Metoderna som använts i studien är: Human centered-design, platsanalys, kvalitativ intervju, observation, workshop, 3D modell och analys av insamlad data. Resultatet av studien visar ett gestaltningsförslag på en aktivitetsbaserad kontorsmiljö som innefattar funktioner som bygger på användarnas behov. Resultatet ska vara ett inspirationsmaterial till Näringslivsenheten för en eventuell framtida genomförning. Samtidigt som det även är ett inspirationsmaterial till övriga användare i kontorsmiljöer som är ute efter en aktivitetsbaserad kontorsmiljö. / This is a study of how an office environment in the form of four cell offices and a conference room can be designed for a local authority. The purpose of the study is to provide a design proposal that visualizes possible solutions for the office's workgroup, which may then be transformed into an activity-based office that will support the users’ needs and working methods. This study was written in cooperation with the Business Unit in the City Hall, Eskilstuna. The working team at the Business Unit wants to be more integrated with each other as it is a major part of their way of working. The walls of the cell offices create barriers between users and negatively affect their preferred way of working. The premises in which the business is located also lacks an identity that reflects their work and their values. The study is based on theory and literature on the spatial environment, activity-based office, office environment zones, cognitive perspective, affordance, color, light and the importance of creativity in the office environment. The methods used in the study are: Human centered-design, site analysis, qualitative interview, observation, workshop, 3D model and analysis of collected data. The result of the study shows a design proposal in an activity-based office environment that includes features based on user needs. The result will be an inspiration to the Business Unit for a possible future implementation. At the same time, it is also an inspiration for other users in office environments that are looking for an activity-based office environment.

The thesis is focused on IS/ICT cost management. The purpose of this thesis is to create an IS/ICT cost model based on the principles of managerial method ABC (Activity Based Costing) for business informatics of selected company. The theoretical part is focused on costs in IS/ICT, their classification and management, with the analyze of the reasons for continuous growth of IS/ICT cost management. A significant part of this section is a characteristic of ABC method and a description of different phases in creation of ABC model. The practical part of the thesis presents a selected company, its business informatics and an organizational structure. Subsequently the current state of IS/ICT cost management is described and analyzed. Based on the analysis and with regard to objectives of the company in the future, a new IS/ICT cost allocation model is designed. For the purpose of calculating and determining of intradepartmental prices for ICT services, a process of allocating and calculating costs is simulated on the new designed model, with the use of current and historical data of the company. At the end of the practical part, the results achieved through the designed model and the results of the current method of allocation and calculation costs are compared.

The theoretical part describes the linkage between process analysis and activity based costing and acts as theoretical framework for practical part of the thesis. Presented cost model is implemented in existing company and information provided by model is used for business process optimization.

The dissertation thesis aims to establish a complex theoretical basis for a measurement of customer's profitability which can be easily used in the practice. The main reason for that is the absence of such publication in the current academic sphere. A combination of management accounting and knowledge of banking enables to achieve the aim. The thesis itself is closely linked to the banking practice. There are derived customer's profitability indicators as modifications of the popular RAROC in which a customer margin is used instead of net profit. There is designed a simplified way of operational cost allocation. Questionnaires and interviews with senior representatives of seven Czech banks helped to identify the most significant labor-intensity factors of corporate customers. The description of principal features of risk costs and derivation of formulas for profitability variances are also the part of the thesis. The theoretical part is followed by the practical one where a contemporary banking practice of corporate customer's profitability measurement on the Czech market is explored. It identified three weak points -- cost allocation, profitability variances and one-year horizon of a calculation. At the end, the theoretical basis is applied on an existing customer portfolio and the result is compared with a currently used customer's profitability measurement.

Transport demand planning in South Africa is a neglected field of study, using obsolete methods to model an extremely complex, dynamic system composed of an eclectic mix of First and Third World transport technologies, infrastructure and economic participants. We identify agent-based simulation as a viable modelling paradigm capable of capturing the effects emerging from the complex interactions within the South African transport system, and proceed to implement the Multi-Agent Transport Simulation Toolkit (MATSim) for South Africa's economically important Gauteng province. This report describes the procedure followed to transform household travel survey, census and Geographic Information System (GIS) data into an activity-based transport demand description, executed on network graphs derived from GIS shape files. We investigate the influence of network resolution on solution quality and simulation time, by preparing a full network representation and a small version, containing no street-level links. Then we compare the accuracy of our data-derived transport demand with a lower bound solution. Finally the simulation is tested for repeatability and convergence. Comparisons of simulated versus actual traffic counts on important road network links during the morning and afternoon rush hour peaks show a minimum mean relative error of less than 40%. Using the same metric, the small network differs from the full representation by a maximum of 2% during the morning peak hour, but the full network requires three times as much memory to execute, and takes 5.2 times longer to perform a single iteration. Our census- and travel survey-derived demand performs significantly better than uniformly distributed random pairings of home- and work locations, which we took to be analogous to a lower bound solution. The smallest difference in corresponding mean relative error between the two cases comes to more than 50%. We introduce a new counts ratio error metric that removes the bias present in traditional counts comparison error metrics. The new metric shows that the spread (standard deviation) of counts comparison values for the random demand is twice to three times as large as that of our reference case. The simulation proves highly repeatable for different seed values of the pseudo-random number generator. An extended simulation run reveals that full systematic relaxation requires 400 iterations. Departure time histograms show how agents 'learn' to gradually load the network while still complying with activity constraints. The initial implementation has already sparked further research. Current priorities are improving activity assignment, incorporating commercial traffic and public transport, and the development and implementation of the minibus taxi para-transit mode.

Contribution of the doctoral thesis for theory and its contribution for further development of medical facilities management and managerial practice are emphasized in the end part thesis.

Olika kontorstrender kommer och går och den flexibla arbetsplatsen har blivit allt vanligare i samhället. Idén om att varje individ själv ska ha möjlighet att välja sin arbetsplats efter olika arbetsuppgifter är grundtanken i det aktivitetsbaserade arbetssättet, en kontrast till de klassiska cellkontoren. Konceptet aktivitetsbaserade flexkontor bygger på att arbetsmiljön utformas i olika zoner efter verksamhetens olika aktiviteter, men tidigare forskning visar på att kontorsformen inte alltid används som den är tänkt eller att arbetsmiljön inte stödjer de behov som finns hos medarbetarna. Den här studien handlar om att undersöka de lugna zonerna i ett aktivitetsbaserat flexkontor. Studien är i samarbete med Försäkringskassans huvudkontor i Stockholm som sedan 2016 arbetat aktivitetsbaserat, men där de anställda idag ofta väljer att sitta på samma plats varje dag. Det har resulterarat i att lugna zonerna idag inte används i någon större utsträckning. Syftet med studien är att undersöka vilka rumsliga behov som användare av ett aktivitetsbaserat flexkontor har i en lugn zon och hur en lugn zon kan kommunicerar dess användande och funktioner.  Intervjuer, frågeformulär och rumsanalys har tillämpats för att få en djupare förståelse om problematiken och för att besvara frågeställningarna för denna studie. Tillsammans litteraturstudier om visuell retorik, visuella element i rummet, zonindelning samt deltagande och inkluderande design så presenteras ett gestaltningsförslag på hur ett rums funktioner kan kommuniceras genom visuella element som form, färg och material och en utformning av en lugn zon som stödjer användares behov.
