Knowledge representation and evaluation an ontology-based knowledge management approach

Competition between Higher Education Institutions is increasing at an alarming rate, while changes of the surrounding environment and demands of labour market are frequent and substantial. Universities must meet the requirements of both the national and European legislation environment. The Bologna Declaration aims at providing guidelines and solutions for these problems and challenges of European Higher Education. One of its main goals is the introduction of a common framework of transparent and comparable degrees that ensures the recognition of knowledge and qualifications of citizens all across the European Union. This paper will discuss a knowledge management approach that highlights the importance of such knowledge representation tools as ontologies. The discussed ontology-based model supports the creation of transparent curricula content (Educational Ontology) and the promotion of reliable knowledge testing (Adaptive Knowledge Testing System).

Preferences of Hungarian consumers for quality, access and price attributes of health care services — result of a discrete choice experiment

In 2010, a household survey was carried out in Hungary among 1037 respondents to study consumer preferences and willingness to pay for health care services. In this paper, we use the data from the discrete choice experiments included in the survey, to elicit the preferences of health care consumers about the choice of health care providers. Regression analysis is used to estimate the effect of the improvement of service attributes (quality, access, and price) on patients’ choice, as well as the differences among the socio-demographic groups. We also estimate the marginal willingness to pay for the improvement in attribute levels by calculating marginal rates of substitution. The results show that respondents from a village or the capital, with low education and bad health status are more driven by the changes in the price attribute when choosing between health care providers. Respondents value the good skills and reputation of the physician and the attitude of the personnel most, followed by modern equipment and maintenance of the office/hospital. Access attributes (travelling and waiting time) are less important. The method of discrete choice experiment is useful to reveal patients’ preferences, and might support the development of an evidence-based and sustainable health policy on patient payments.

Az árak észlelése és értékelése(Perception and Evaluation of Prices)

A 2008-ban kezdődött gazdasági válság a korábbiaknál is fontosabbá tette az árakat a vásárlók számára. Azt eddig is mindenki tudta, hogy az árak alapvetően befolyásolják a fogyasztók vásárlási döntését. Arra a kérdésre azonban, hogy miképpen, már nem mindig tudunk pontos választ adni. A közgazdaságtan szerint az árak csökkenése növeli a fogyasztók vásárlási hajlandóságát és fordítva, az árak emelkedése kisebbíti azt. A valóság azonban nem mindig írható le közgazdaságtani fogalmakkal vagy matematikai képletekkel. _______ Since the beginning of the global economic recession prices have become more and more important for sellers and buyers. To study the role of prices in consumer behaviour is a rather new field of marketing research. The paper starts out from the fact that prices can be regarded as a multidimensional stimulus, which influences the purchasing decision of consumers. The study describes the process how, in this multidimensional pricing environment, consumers get from the perception through the evaluation of prices to the purchasing decision. According to the model constructed by the author the perception of prices depends on the presentation of prices and on the willingness and ability of people to numerically perceive and evaluate the different presentations of prices. In the process how consumers get from the perceived prices through the excepted prices to the purchasing decision the perceived value plays the most important role. The perceived value is motivated by the internal and external reference prices and the perceived reference value. The paper comes to the conclusion that in recession and post recession times, companies are compelled to understand these processes better to be able to set their price points according to the changing buyers behaviour.
