NOTES 3 To minimize any context bias associated with survey fatigue or priming from prior questions, the two name generator questions were located close to the start of the survey. They were placed after a small number of questions about basic internet use that were used to establish trust with the survey participant. 4 Previous research has identified a high degree of overlap between those wit...

In this paper, we carry out a study about the main themes treated by the International Journal of Information Technology & Decision Making during its ̄rst 10 years (2002 2011). The themes are detected, quanti ̄ed and visualized using an approach that combines performance analysis and science mapping. Bibliometric maps based on co-word analysis will help us to visualize the division of the journal...

The theoretical and empirical evidence on the relationship between the strength of patent protection in a country and technology transfer of various kinds to that country is surveyed. The conclusions are that stronger patent protection encourages FDI and technology transfer to mid-level developing countries, but that there is little clear evidence that stronger patent protection encourages indi...

We describe a human-centered multimodal framework for automatically measuring cognitive changes. As a proof-ofconcept, we test our approach on the use case of stress detection. We contribute a method that combines non-intrusive behavioral analysis of facial expressions with speech data, enabling detection without the use of wearable devices. We compare these modalities’ effectiveness against ga...

The rapid growth of the availability of wearable biosensors has created the opportunity for using biological signals to measure worker performance. An important question is how to use such signals to not just measure, but actually predict worker performance on a task under stressful and potentially high risk conditions. Here we show that the biological signal known as galvanic skin response (GS...

A power divider (PD)/ power combiner (PC) with high quality factor and enhanced output ports isolation using substrate integrated waveguide (SIW) technology is proposed. An SIW cavity is designed to provide a high quality factor filtering response and an SMD resistor is attached between two output ports to realize the high isolation. The value of the applied resistor is calculated by using the ...
