Fringe phenomena - Tradução em português

Olá! Alguém poderia me sugerir uma tradução para "fringe phenomena", dentro deste contexto?

In the present paper, I will provide some arguments for a broader redefinition of our concept
of translation following Tymoczko’s (2003, 2007) call for “enlarging translation”, based on
the investigation of translational “fringe phenomena” in the area of science communication,
specifically expert-to-non-expert communication. I will also argue that definitional work is
necessary and indispensable for any discipline, taking a philosophy of science perspective and
harnessing Popper’s searchlight theory of scientific knowledge (Popper 1979). I will then
move on to discuss the implications which a broadening of the concept of translation to
include seemingly marginal “fringe” phenomena like science communication/science
popularisation has with regard to (a) the relation between translation theories and real-world
translation practice, (b) the internal coherence of Translation Studies as an academic
discipline and (c) its position among and relation to other disciplines working on similar,
neighbouring objects of study.
