We investigate the role of respect and monetary gifts in the service industry. We report findings from purchases of more than 800 doner durum, a common lunch snack. Prior to the food’s preparation, we either give a compliment about the product, or a monetary gift by tipping. We repeat the interaction on five consecutive days. Our findings show that salespersons exhibit positive reciprocity in r...

BACKGROUND In altricial species, maternal stimuli have powerful effects on amygdala development and attachment-related behaviors. In humans, maternal deprivation has been associated with both "indiscriminate friendliness" toward non-caregiving adults and altered amygdala development. We hypothesized that maternal deprivation would be associated with reduced amygdala discrimination between mothe...

This paper presents a perceptual experiment on the friendliness of the synthesized Standard Chinese. Based on the acoustic investigation of friendly speech, tonal pitch, phone duration and spectral energy distribution were adjusted in synthesis and the synthesized stimuli were subjected to perception test. It was found that: (1) Friendliness of synthesized speech could be achieved via adjusting...

In this work, we study how TCP-friendliness of a ratebased control protocol is affected by the different parameterisation of RED. We also explore the range of optimal RED parameter values for ensuring the TCP-friendliness of the competing connections. We choose TCP-Friendly Rate Control (TFRC) protocol [5] as the competing source againsts TCP Sack. Our results show that different RED parameteri...

Many of today’s websites have recognised the importance of mobile friendly pages to keep users engaged and to provide a satisfying user experience. However, next to the experience provided by the sites themselves, advertisements, when clicked, present users with landing pages that are not necessarily mobile friendly. We explore what type of features are able to characterise the mobile friendlin...
