She is the author of Gender Quake: Poems and producer of the forthcoming autobiographical film Transilience.
Transilience, the result of Sheveck's Theory of Unified Field, allows the Hainish planets, no matter how far in time and space, to establish a relation faster than lightspeed and to achieve a mutual understanding and cooperation.
Yet despite her transilience, her work hardly outdoes Weihui's in cosmopolitan scope, for Weihui's perceptions derive from Shanghai's international community, in some ways even less narrowly bounded than the world of Shi Guoying.
For example, Wright's shifting balance theory (Wright 1931, 1932) and Templeton's genetic transilience mode of speciation (Templeton 1980, 1981; Carson and Templeton 1984) assume that epistasis exists for loci that affect fitness.
Epistasis plays a critical role in a variety of theories of evolution and speciation, including Wright's (1978) shifting-balance theory, Schmalhausen's (1949) theory of stabilizing selection, Waddington's (1957) theory of canalization and genetic homeostasis, Mayr's (1963) concept of the unity of the genotype and genetic revolutions at speciation, Carson's (1968, 1982) founder-flush theory of speciation, and Templeton's (1980a,b) theory of genetic transilience.
This window of evolutionary opportunity is thought to be very limited (Templeton 1980b; Barton and Charlesworth 1984), although Templeton (1980a) described a series of population structure conditions that enhance the possibility of a genetic transilience while passing through a bottleneck.
A discussion of the distinction of the genetic-revolution model from the alternatives of genetic transilience and founder flush can be found in Carson and Templeton (1984), so only a brief distinction will be presented here.
Thus, genetic transilience is triggered by drift effects at major loci that are induced by the initial founder event and that subsequently interact with genetic architectures characterized by much gene-action level epistasis and with recombination to produce an expanding founding population that has enhanced responsiveness to selection (just the opposite of the genetic revolution model) and is thereby subject to rapid evolutionary change.
Note that the demographic and basic genetic conditions (the roles of epistasis and recombination) of the genetic transilience and founder-flush models are mechanistically compatible and that these models differ primarily in the timing and triggering agent of selection.
It spawned several similar theories with confusing names, including founder-flush speciation, flush-founder speciation, flush-crash speciation, and genetic transilience.
