An S-receptor kinase (SRK) cDNA, SRK-910, from the active S-locus in a self-incompatible Brassica napus W1 line has been isolated and characterized. The SRK-910 gene is predominantly expressed in pistils and segregates with the W1 self-incompatibility phenotype in an F2 population derived from a cross between the self-incompatible W1 line and a self-compatible Westar line. Analysis of the predi...

Ancient polymorphism preserved at the self-incompatibility locus facilitates investigation of historical occurrences far older than extant species. We outline two ways in which studies of the S-locus can provide insights into patterns of speciation. First, we review evidence concerning the prevalence of founder events in speciation. A dramatic population size reduction is expected to reduce seq...

n TESOL methodology is said to have moved “beyond methods” (Richards, 1990, p. 35) to the “postmethod condition” (Kumaravadivelu, 1994, p. 27). Although “postmethod pedagogy” (Kumaravadivelu, 2001) has freed us as TESOL professionals from many of the constraints of the concept of method and invigorated our practices by providing new options to the classroom teacher, the postmethod condition has...

Rȩbilas argues that time-reversal can occur even in an indeterministic system. This hypothesis is untestable, hence lying beyond physics. PACS: 01.55.+b; 03.65.Bz; 04.70.Dy; 05.70.-a

We consider the most general solar model, using the neutrino fluxes as free parameters constrained only by the solar luminosity, and show that the combined solar neutrino data exclude any astrophysical solution at 98% C.L. Our best fit to the 7 Be and 8 B fluxes is respectively <7% and 37±4% of the standard solar model prediction, but only with a large χ 2 (5.6 for 1 d.f.). This best fit to the...

Exploiting the tension between two dynamics of quantum theory (QT) in Wigner's Friend thought experiment, we point out that standard QT leads to inconsistency observed probabilities measurement outcomes superobservers: Wigner and his Student. To avoid such inconsistent predictions QT, hypothesize distinct perspectives. The first one is ``absoluteness (AoM),'' is, any process an absolute event i...

Genetically controlled self-incompatibility systems represent links between genetic diversity and plant demography with the potential to directly impact on population dynamics. We use an individual-based spatial simulation to investigate the demographic and genetic consequences of different self-incompatibility systems for plants that vary in reproductive capacity and lifespan. The results supp...

We examined whether positive and negative affect motivates verbal and spatial working memory processes, respectively, which have implications for the expenditure of mental effort. We argue that when emotion promotes cognitive tendencies that are goal incompatible with task demands, greater cognitive effort is required to perform well. We sought to investigate whether this increase in cognitive ...

Relational Quantum Mechanics (RQM) claims to be an interpretation of quantum theory [see arXiv:2109.09170, which appears in the Oxford Handbook History Interpretation Physics]. However, there are significant departures from theory: (i) RQM measurement outcomes arise interactions entangle a system $S$ and observer $A$ without decoherence, (ii) such outcome is "fact" relative $A$, but it not fact...
