We must be faithful to the original meaning of the source language (SL) and accurate in our translation but flexible enough to communicate naturally to the target language (TL) readers. While it may seem hopeless to truly communicate with all languages and cultures, with the growing global economy and the more interdependent we become, it is even more important that we continue to try to blend our thoughts and hearts together. So with foolish confidence and wise trepidation, this paper will wade into the age long discussion on the practice of translation and teaching, attempting to reconcile the theories of literal or semantic and free or communication translation theories.展开更多

Senders may adjust signaling rate depending on receiver identity, presence of audiences, or noise masking the signal, all of which can affect the benefits and costs of signal production. In the cooperative breeding meerkat Suricata suricatta, group members emit soft contact calls, termed as ＂close calls＂, while foraging in order to maintain group cohesion. Here, we investigated how the close calling rate during foraging was affected by the presence of pups, that produce continuous, noisy begging calls as they follow older group members. Adults decreased their overall close call rate substantially when pups were foraging with the group in comparison to periods when no pups were present. We suggest this decrease was likely due to a masking effect of the loud begging calls, which makes the close call function of maintaining group cohesion partly redundant as the centrally located begging calls can be used in- stead to maintain cohesion. There was some support that adults use close calls strategically to at- tract specific pups based on fitness advantages, that is, as the philopatric sex, females should call more than males and more to female pups than male pups. Dominant females called more than dominant males when a pup was in close proximity, while subordinates showed no sex-based dif- ferences. The sex of the nearest pup did not affect the calling rate of adults. The study shows that meerkats modify their close call production depending on benefits gained from calling and provides an example of the flexible use of one calling system in the presence of another, here contact calls versus begging calls, within the same species.展开更多
