It is essential to understand the consumption pattern of food and how it changes over time to formulate sound economic policies as well as marketing and pricing strategies. In this study, we estimate the Quadratic Almost Ideal Demand System with six rounds of the Family Income Expenditure Survey exploiting the conditional linearity of the demand system. We find that the Filipino diet has become...

Goal models and business process models are complementary artifacts for capturing the requirements and their execution flow in software engineering. Usually, goal models serve as input for designing business process models, and it requires mappings between both types of models. Due to the large number of possible configurations of elements from both goal models and business process models, deve...

Increasing market demands concerning customer requirements and market pressure from competitors force several enterprises to diversify their product range. Offering more and more product variants has the implicit impact of growing development process complexity. Although many configuration problems can be solved with knowledge-based configuration, the usage of configuration tools is very often ...

Human-centred design in the adaptive virtual interface is about supporting the intentionality of the user. An operator has a purposeful motivation in undertaking activity in the virtual environment. This can range from taskfocused activity in a vocational sense, such as telepresence surgery or rehearsing mission tactics in a flight simulator, to the purely recreational exploration of a cyberspa...

People are able to interact with domain-specific applications in smart environments and get assistance with specific tasks. Current intelligent agents (IAs) tend to be limited to specific applications. In order to engage in more complex activities users have to directly manage a task that may span multiple applications. An ideal personal IA would be able to learn, over time, about these tasks t...

A common problem in spoken dialogue systems is finding the intention of the user. This problem deals with obtaining one or several topics for each transcribed, possibly noisy, sentence of the user. In this work, we apply the recent unsupervised learning method, Hidden Topic Markov Models (HTMM), for finding the intention of the user in dialogues. This technique combines two methods of Latent Di...

Integrating predictions from the theory of human values with the theory of planned behavior (TPB), our primary goal is to investigate mechanisms through which individual values are related to entrepreneurial career intentions using a sample of 823 students from four European countries. We find that openness and self-enhancement values relate positively to entrepreneurial career intentions and t...

Counterfactual thoughts (CFTs) are imagined alternatives to an actual event, and are pervasive in our daily lives. It is not unusual for one to think of what might have been if only a few subtle details of the past had been different. CFTs often arise from disconfirmation of expectations. Such thoughts have been proposed to influence satisfaction, disappointment and continuance intentions in th...
