Do creative ad executions like large ad sizes and intrusive ad formats that enhance communication outcomes and clickthroughs immediately after ad exposure persist over time? In examining this question, we focus on the role of advertisement size (large vs. small) and ad exposure format (intrusive vs. voluntary) on immediate and delayed brand recall, ad recognition and brand attitude in web-based...

Faced with an abundance of advertising messages, Internet users allocate only minimal cognitive resources to advertising. What are the effects of pop-up ads for a new brand viewed at low level attention, and then measured when the Internet users have forgotten having seen them? In the theoretical context of processing fluency and implicit memory, the experiment (n = 398) studied the effects of ...

This paper proposes a novel approach for identifying risks in executable business processes and detecting them at run-time. The approach considers risks in all phases of the business process management lifecycle, and is realized via a distributed, sensor-based architecture. At design-time, sensors are defined to specify risk conditions which when fulfilled, are a likely indicator of faults to o...

Robust autonomous agents should be able to cooperate with new teammates effectively by employing ad hoc teamwork. Reasoning about ad hoc teamwork allows agents to perform joint tasks while cooperating with a variety of teammates. As the teammates may not share a communication or coordination algorithm, the ad hoc team agent adapts to its teammates just by observing them. Whereas most past work ...

The conventional wisdom in web design literature is that an online shopping website should be free of distracting features; such as animated banners, pop-ups and floating advertisements, as they cause annoyance and disrupt the process of pre-purchase evaluation, leading to poorer purchase decisions. Yet, the recently formulated Unconscious Thought Theory (UTT) suggests that the use of these fea...
