Infanticide has recently been observed in several primate species while female counterstrategies are seemingly rare. The question of why mothers do not increase their resistance to infanticide is investigated using a haploid two-locus model. A hypothesis that mothers can recover lost offspring by gaining more grandchildren is rejected in most cases, and it is shown that costs and benefits for b...

This article is about one feature which was partly introduced 30 years ago with the development of multi windows operating systems. It is about the movability of screen objects not according to some predetermined algorithm but by the direct user action. Many years ago it was introduced on a very limited basis and nothing was improved since then. Smartphones and tablets give direct access to scr...

We present FlightPath, a novel peer-to-peer streaming application that provides a highly reliable data stream to a dynamic set of peers. We demonstrate that FlightPath reduces jitter compared to previous works by several orders of magnitude. Furthermore, FlightPath uses a number of run-time adaptations to maintain low jitter despite 10% of the population behaving maliciously and the remaining p...

Punishment typically involves depriving violators of resources they own such as money or labor. These resources can become revenue for authorities and thus motivate profitseeking punishment. In this paper, we design a novel experiment to provide direct evidence on the role punishment plays in communicating norms. More importantly, we provide experimental evidence indicating that if people know ...

Although people are often astonished by the high rates of obedience in Milgram’s famous studies, research on social influence processes in other settings provides considerable insight into why so many of Milgram’s participants continued to press the shock levers all the way to 450 volts. That research suggests that four situational features Milgram built into his experimental procedure contribu...

There is a debate in the extant literature concerning whether the Internet stimulates political participation. We examine both whether Internet use encourages traditional participation, such as campaignand election-centered acts, and nontraditional participation, including protest/resistance-centered acts in the East Asian context. In doing so, we are also able to explore the Asian Values hypot...

In Berkeley’s Passive Obedience, moral duties are negative and positive as well civil or legal natural. Natural from God therefore valid norms. The supreme authority makes laws. We must obey the law because loyalty to power is one of our natural duties: be loyal obey, which means ‘do not rebel.’ This a duty such categorical unconditional. Positive conditional on conscientious acceptance. I show...
