The objective of this paper is to present a brief introduction to the doctoral thesis of the author. The content of the thesis identifies the critical success factors for obtaining business intelligence success, measured as use, user satisfaction, net benefits and individual impact from an end user’s perspective in the public sector. The author explores the options regarding how to combine task...

Classical mechanism design assumes that an agent’s value of any determined outcome depends only on its private information. However in many situations, an agent’s value of an outcome depends on the private information of other agents in addition to its private information. In such settings where agents have interdependent valuations, strategy-proof mechanisms have not been proposed yet, and whe...

This paper describes a collaboration between two PhD students. The first author is developing a course generator (CG) for a Web-based e-learning environments (WBLE) [3]. A CG generates sequences of learning objects according to the learner’s goals and individual properties. The assembling process is knowledge intensive: assembling courses that implement modern pedagogical theories requires a fr...

Cartograms are maps in which areas of geographic regions (countries, states) appear in proportion to some variable of interest (population, income). Cartograms are popular visualizations for geo-referenced data that have been around for over a century. Newspapers, magazines, textbooks, blogs, and presentations frequently employ cartograms to show voting results, popularity, and in general, geog...

Leisure and recreation facilities are strongly intertwined due to their mutual dependencies. Thus, they build up invisible networks. Leisure and recreation facilities are one of the imperative components for socio-cultural, psychological, and economic development. In the spectrum of sustainable development, it is not possible to initiate development process without strategically planning for le...

When animals are transported and pass through customs, some of them may have dangerous infectious diseases. Typically, due to the cost of testing, not all animals are tested: a reasonable selection must be made. How to test effectively, yet avoid cataclysmic events? First, we extend a model proposed in the literature for the detection of invasive species to suit our purpose. Secondly, we explor...

Cartograms are maps in which areas of geographic regions (countries, states) appear in proportion to some variable of interest (population, income). Despite the popularity of cartograms and the large number of cartogram variants, there are few studies evaluating the effectiveness of cartograms in conveying information. In order to design cartograms as a useful visualization tool and to be able ...

In this paper, an integrated framework for knowledge audit and capture using the task analysis approach is presented. We first identify the types of knowledge that could be ascribed to tasks and analyze a task by breaking it down into subtasks and task elements. We then identify the skills and knowledge required to perform the tasks at this level. The framework is validated and tested on an exp...

Cognitive task analysis has been used in ITSs to predict students’ performance, improve curricula and to determine appropriate feedback. Typically, the learning factors/knowledge components have been determined only for the use in one ITS or curriculum and therefore, general frameworks were not applied. Moreover, the result is sometimes rather unsystematic and not reusable across domains. Howev...

The purpose of this chapter is to show how it is possible to efficiently extract the structure of a set of objects by use of the notion of proportional analogy. As a proportional analogy involves four objects, the very naïve approach to the problem, has basically a complexity of O(n4) for a given set of n objects. We show, under some conditions on proportional analogy, how to reduce this comple...
