This paper studies targeted advertising in two sided markets. Two platforms, with different targeting abilities, compete for single-homing consumers, while advertising firms are multi-homing. We show that the platform with a higher targeting ability will attract more consumers and have more advertising firms. When the targeting ability of either platform increases, all consumers benefit as they...

The strong connection between physiological adaptations to training and the level of technical abilities of competitors is often difficult to establish since judo is a sport in which technique is dominant, while the physiological characteristics and their parameters make up the basis on which the judo athlete builds his individual technique and tactics. The aim of the paper is to present the re...

Therefore, it is important for individuals to accurately assess their IT knowledge because accurate self-assessment is critical to effective self-management. Metacognition represents individuals' self-monitoring and self-regulating abilities, and plays a key role in self-managed learning. This study examine...

The process of ageing causes the physical abilities of the body to decline. This research aims to gather data and understanding of the nature of this process in relationship to the kitchen and the use of utensils. With this data, a design guide can be written to help avoid some of these difficulties by aiding inclusive design. The research is being undertaken at three universities, with three d...

Learning by reading is an important scientific problem because it requires modeling a wide range of human abilities. It also could break the knowledge engineering bottleneck, enabling the bootstrapping of intelligent systems via interaction with people using natural language. This paper outlines our progress on creating a 2 generation learning by reading system, focusing on three main areas: Mu...

ac.uk Abstract Range shift, a widespread response to climate change, will depend on species abilities to withstand warmer climates. However, these abilities may vary within species and such intraspecific variation can strongly impact species responses to climate change. Facing warmer climates, individuals should disperse according to their thermal optimum with consequences for species range shi...

Studies have found that shamanic practices are associated with statistically significant reductions in mood disturbance relative to baseline. However, contrary results were obtained for non-shamanic practitioners exposed to shamanic-like techniques. These inconsistent results may be partially due to a personality trait referred to as schizotypy, which has been demonstrated to influence suscepti...
