The Steering Committee decided to approach the Editors of the Australasian Journal of Combinatorics with a proposal to publish selected refereed papers from the conference. We were delighted when the proposal was accepted, and the Australasian Journal of Combinatorics joined other journals such as Advances in Applied Mathematics, Annals of Combinatorics, Electronic Journal of Combinatorics, Jou...

Sweeney, K.E., Roering, J.J., Ellis, C., 2015. Experimental evidence for hillslope control of landscape scale. Science 349, 51–53. This study derived laboratory experiments to test the landscape evolution theory, which states that climate sets the scale of landscape dissection through the competition between diffusive and advective processes. Convex hillslopes are produced through diffusive pro...

A recent study claimed that inhibitory processes in spoken language processing are relatively slow and may be strongly reduced in listening conditions that require extra processing resources. Time compression of a sentence context did not reduce facilitation of a congruent word target, but inhibition of word targets that were incongruent with the preceding sentence context was strongly reduced....

In Drosophila melanogaster, sperm and accessory gland proteins ("Acps," a major component of seminal fluid) transferred by males during mating trigger many physiological and behavioral changes in females (reviewed in ). Determining the genetic changes triggered in females by male-derived molecules and cells is a crucial first step in understanding female responses to mating and the female's rol...

Repression of competition within groups joins kin selection as the second major force in the history of life shaping the evolution of cooperation. When opportunities for competition against neighbors are limited within groups, individuals can increase their own success only by enhancing the efficiency and productivity of their group. Thus, characters that repress competition within groups promo...

Acoustic signals used by males to attract females are among the most prominent examples of secondary sexual traits, yet we have only limited understanding of their genetic architecture. Male crickets produce a calling song to attract females and then switch to a courtship song that incites mounting by females once they are at close range. Although we know much about the genetics of cricket call...

Males among many species, including humans, evaluate cues of sperm competition risk and adjust accordingly their sperm competition tactics. The number of potential sexual rivals can serve as an index of sperm competition risk. Therefore, men may adjust their in-pair copulatory interest in accordance with the presence of sexual rivals. Using self-reports from 45 married men, we test the hypothes...

Three experiments investigated competition between word-object pairings in a cross-situational word-learning paradigm. Adults were presented with One-Word pairings, where a single word labeled a single object, and Two-Word pairings, where two words labeled a single object. In addition to measuring learning of these two pairing types, we measured competition between words that refer to the same ...

The role of competition in healthcare is much debated. Despite a wealth of international experience in relation to competition, evidence is mixed and contested and the debate about the potential role for competition is often polarised. This paper considers briefly some of the reasons for this, focusing on what is meant by “competition in healthcare” and why it is more valuable to think about th...
