Furthermore, the proportion of aggression towards bouncers and barmaids between 3 00 and 3 30 was slightly higher than for aggression between patrons.
Aggressive behaviours can be ranked according to apparent escalation towards full fighting [ 14], and the more escalated behaviours were more common when the overall proportion of aggression was greater (figure 1), indicating that both the proportion and the intensity of aggression were affected by wasp age and host size.
We quantified counter-aggression as the proportion of aggressive interactions with counter aggression (any aggressive response, including aggressive screams).
Most of the physical aggression and a significant proportion of the verbal aggression experienced by clinical staff are the result of patient interactions and generally regard clinical issues arising from patient care.
Aim 1 Unadjusted proportions were calculated to estimate prevalence and severity of aggression, and the proportion that involve drinking.
As expected, higher ranking matrilines initiate a significantly greater proportion of fights using intense aggression than lower ranking matrilines (β = −0.009, P<0.0001; Figure 3).
In these 4 a.m. confrontations I experience feelings of aggression in direct proportion to my perception of personal failure at the most important job of my life.
As predicted, with increasing patch perimeter, the ability of the large (dominant) fish to defend the patch decreased, as reflected by a decrease in the frequency of aggression and the proportion of the aggression by the dominant.
A significant proportion of the participants displayed verbal aggression (n = 25, 41%), and 18 (29.5%) displayed physical aggression, such as hitting, kicking, throwing objects and tearing up materials.
As predicted, matrilines with a lower average coefficient of relatedness participated in a higher proportion of fighting-events involving intense aggression in which both combatants were members of that matriline and directed intense aggression at one another (β = −0.48, P<0.0001; Figure 5).
The predicted proportion of fighting-events involving intense aggression that are between kin, calculated for minimum, mean, and maximum values of average coefficients of relatedness observed in the study groups, are 13.7%, 8.8%, and <<1%, respectively.
