Violence is a curvilinear function of temperature in Dallas: A replication.

Abstract

Data on weather and aggravated assaults were obtained to determine whether the curvilinear relationship between temperature and violence previously observed in Minneapolis, Minnesota (E. G. Cohn & J. Rotton, 1997), could be replicated. The data consisted of calls for services received by police in Dallas between January 1, 1994, and December 31, 1995. Controlling for holidays, school closings, time of day, day of the week, season of the year, and their interactions, moderator-variable autoregression analyses indicated that assaults were an inverted U-shaped function of temperature. Replicating past research, the curvilinear relationship was dominant during daylight hours and spring months, whereas linear relationships were observed during nighttime hours and other seasons. The results are interpreted in terms of routine activity theory and the negative affect escape model of aggression.

Effect of wind on stock market returns: evidence from European markets

“…Weather was also found to influence human behaviour, for example, violent behaviour (Baron and Ransberger, 1978;Anderson, 2001), interpersonal interactions (Cunningham, 1979;Schneider et al, 1980;Rotton and Cohn, 2000) and performance (Allen and Fisher, 1978;Pilcher et al, 2002). On good weather days, people tip more generously and are more like to answer questionnaires (Cunningham, 1979), as well as give money to beggars (Lockard et al, 1976).…”

It is well recognized that pleasant weather causes a good mood and nasty weather causes a bad mood (e.g.…”
