Pretending that this is based on chance encounters actively puts children at risk, selling a palatable story (abusers are strangers in dirty raincoats) rather than the truth.
Outgoing Atta cephalotes workers are also known to experience higher encounter rates than returning ants [37], and it has been speculated that they may actively seek encounters with returning ants for information acquisition.
It actively avoids encounters with stoats, though female weasels are less likely to stop foraging in the presence of stoats, perhaps because their smaller size allows them to quickly escape into holes.
The two species usually were spatially separated (i.e., small colonies inhabiting distant twigs), and P. gracilis generally actively avoids encounters with other animals by, e.g., moving to the opposite side of the twig.
In contrast to the dental care system, a similar situation in the general health care system was encountered actively.
The McKinney Police Department claimed in a Facebook statement that the clash came about after officers encountered teens "actively fighting" and that "first responding officers encountered a large crowd that refused to comply with police commands".
Importantly, the up-regulating element common to all these factors is iron-restricted conditions, indicating that the iron-replete environment encountered by actively swarming cells explains, at least in part, their reduced expression of virulence determinants.
Although there is evidence that at least some adults in the UK recognise and actively associate with previously encountered conspecifics on breeding colonies (Pomeroy et al. 2005), mothers from the eastern Atlantic have been shown to fail to recognise their own pups (McCulloch et al. 1999; McCulloch and Boness 2000).
There is an even larger pool of differentiated T cells, called CD4+CCR5+ T cells, and plasma cells diffusely scattered throughout the intestine's lamina propria that serve as the "effector" arm of the intestinal immune system, actively battling antigens first encountered by the Peyer's patches (Mowat et al. 1997).
What appears to be a lack of adverse effects on care may in some cases be more complex, as seen in the study by Young et al., where patients actively minimized problems they encountered with the technology and assumed blame when things were not working properly [ 76].
