She is the author of Gender Quake: Poems and producer of the forthcoming autobiographical film Transilience. Her research and activist interests include LGBT rights, feminism, racial and economic justice, sex worker rights, fat liberation, and film/media criticism, Joelle is also the director of "TransGender New Hampshire (TG-NH) and the founder and co-chair of the Fat Studies Interest Group and the Transgender Caucus in the National Women's Studies Association (NWSA).]
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.
The telling of the story by women nourishes or fuels the space ship (or means to the new universe) itself through expanded perceptions of shared narration or "transilience." In a patriarchal society whose belief in science is fostered daily by victories over nature or space or disease, the concept that talking about beliefs makes them true has the same power, according to Barr, as the power of the children's clapping in reviving Tinkerbell.
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.
Second, and more important, we assume that speciation results from the accumulation of complementary genes and not from "peak shifts" or "transilience events." In short, here as elsewhere (Orr 1995; Turelli and Orr 1995), we attempt to work out the theoretical consequences of the recent experimental findings in the genetics of speciation - findings that strongly suggest that postzygotic isolation results from the fixation of genes having no deleterious effects on their normal genetic backgrounds.
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. Although these theories are distinct (Carson and Templeton 1984; Barton and Charlesworth 1984), they also share much common ground in that all of them are based on evolution of phenotypes that result from the harmonious interaction of alleles at different loci.
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.
Under genetic transilience, there is no radical overall reduction in levels of genetic variation in the founding population as in the genetic revolution model, but the initial founder effect can occasionally induce severe allele frequency alterations at one or more of the major loci, including fixation.
It spawned several similar theories with confusing names, including founder-flush speciation, flush-founder speciation, flush-crash speciation, and genetic transilience. The subtle differences among these theories were described by Carson and Templeton (1984) and Provine (1989).
