This paper treats the stability of two superposed gravitating streams rotating about the axis transverse to the horizontal magnetic field. The critical wave number for instability is found to be affected by rotation for propagation perpendicular to the axis about which the system rotates. The critical wave number for instability is not affected by rotation when waves propagate along the axis of rotation. The critical wave number is affected by both the magnetic field and the streaming velocity in both cases. Both the magnetic field and the rotation are stabilizing, while the streaming velocity is destabilizing.
Using an empirical approach, this study addresses the question whether followers of different religious beliefs (Christians, Muslims, and Hindus), as well as Atheists and Agnostics manifest different senses of humour when rating a variety of jokes. The study further investigates whether one’s religious background influences the threshold of what is considered offensive. And finally, it seeks to answer whether jokes targeting religions other than one’s own are always perceived as funnier. Analysing the results of a public survey (N=783) containing a blend of religious and non-religious jokes (including irreverent ones), we found that Hindus demonstrate overall the highest humour appreciation among all the groups, while Christians were the least amused by the jokes presented on the survey. Muslims had overall robust humour responses, despite reporting the highest incidence of being offended. Atheists were the least likely to be offended, and they generally enjoyed irreverent jokes. All groups agreed that if a joke was seen as offensive, its funniness was reduced.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
