Females of the stream goby Rhinogobius sp. DA with paternal care favor males courting in fast water currents, whereby they mate males of high parental ability. Here we examined female choice of male nest size of this goby in laboratory. The dichotomous choice experiment clearly indicated that females prefer large nests. Spawning at large nests seems to improve egg survival rates in natural habi...

Restricted domains over voter preferences have been extensively studied within the area of computational social choice, initially for that are total orders set alternatives and subsequently dichotomous—i.e., correspond to approved disapproved alternatives.

Adding versatile interactions to imperative programming – C, Java and Android – is an essential task. Unfortunately, existing languages provide only limited constructs for user interaction. These constructs are usually in the form of unbounded quantification. For example, existing languages can take the keyboard input from the user only via the read(x)/scan(x) statement. Note that the value of ...
