The article examines the influence of a child on the buying behavior of parents in the Czech Republic. Previous studies claim that Czech consumers are only slightly influenced by the marketing tool of the product package when purchasing food. Whereas children are increasingly becoming influencers of consumption, the question arises, whether or not the parent succumbs to their requesting through...

In this paper, we develop a qualitative theory of influence diagrams that can be used to model and solve sequential decision making tasks when only qualitative (or imprecise) information is available. Our approach is based on an orderof-magnitude approximation of both probabilities and utilities and allows for specifying partially ordered preferences via sets of utility values. We also propose ...

Finding an optimal elimination ordering is a NP-hard problem of crucial importance for the efficiency of the Influence Diagrams evaluation. Some of the traditional methods for determining the elimination ordering use heuristics that consider that potentials are represented as tables. However, if potentials are represented using binary trees traditional methods may not offer the best results. In...

The potential influence diagram is a generalization of the standard "conditional" influence diagram, a directed network representation for probabilistic inference and decision analysis [Ndilikilikesha, 1991). It allows efficient inference calculations corresponding exactly to those on undirected graphs. In this paper, we explore the relationship between potential and conditional influence diagr...

This article aims at discussing how Dynamic Decision Network (DDN) can be employed to tackle the challenges in modeling temporally variable scientific inquiry skills and provision of adaptive pedagogical interventions in INQPRO, a scientific inquiry exploratory learning environment for learning O’level Physics. We begin with an overview of INQPRO and a highlight of the computer algorithm as wel...

To simplify the task, the current Eurocode provisions apply fatigue load model 3 and damage equivalence factors (k). However , the fatigue load model and th...

Without a systematic assessment mechanism, it is hard for teachers to design e-learning courseware and assess students’ on-line learning behaviors. This is a common issue found in most authoring tools available all over the world. Furthermore, some authoring tools are powerful but not standard compliant. To overcome these drawbacks, we propose a courseware design tool with the theory of concept...

This article examines the structural effects of platform certification on the supply of complementary products. Drawing on the exploratory case of mobile application markets, the article highlights the broader market effects of competing platforms and their certifications on a platform-based complementary product market. The case suggests that platform certifications influence market intermedia...

Consider a doctor choosing a treatment for an uncertain disorder for which there are n costly tests available. Based on the test results observed so far, the doctor can either order another test or proceed to the treatment decision. Although test sequencing is a problem that arises frequently in many decision situations, finding an exact solution is NP-hard with respect to n. In this paper, we ...
