Genetic surfing describes the spatial spread and increase in frequency of variants that are not lost by genetic drift and serial migrant sampling during a range expansion. Genetic surfing does not modify the total number of derived alleles in a population or in an individual genome, but it leads to a loss of heterozygosity along the expansion axis, implying that derived alleles are more often i...

Do extreme sports contribute to higher biomechanical stress compared to other sports? Kite surfing is one of the upcoming popular extreme sports, where very few have studied the mechanical forces that act on the body. There are several factors that contribute to mechanical stress, and for preventing injuries it is of interest to investigate how these forces affect the body and how we can develo...

A mixed-design experiment was conducted to explore differences between searching and surfing on cognitive and emotional responses to online news. Ninety-two participants read three unpleasant news stories from a website. Half of the participants acquired their stories by searching, meaning they had a previous information need in mind. The other half of the participants acquired their stories by...

The authors examined social capital, self-esteem, popularity, need for accessibility to friends, and stress as gendered predictors of cyber technology use in 149 undergraduates. The authors investigated four kinds of cyber technology use: social networking, texting, internet surfing, and MP3 player listening. Stress was the most consistent predictor of cyber technology use in men (social networ...

Much of our current knowledge about the genetic dynamics in range expansions originates from models, simulations and microcosm experiments that need to be corroborated by field data. Here, we report a neutral genetic pattern that matches the predictions of the genetic surfing theory. Genetic surfing occurs when repeated founding events and genetic drift act on the wave of advance of an expandin...

One approach to mitigate shoulder surfing attacks on mobile devices is detect the presence of a bystander using phone’s front-facing camera. However, person’s face in camera’s field view does not always indicate an attack. To overcome this limitation, novel data collection study (N=16), we analysed influence three viewing angles and four distances success attacks. In contrast prior works that m...
