How and When Selection Experiments Might Actually be Useful.

Laboratory natural selection and artificial selection are vital tools for addressing specific questions about evolutionary patterns of variation. Laboratory natural selection can illuminate whether a putative selective agent is capable of generating long-term, sustained changes in individual traits and suites of traits. Artificial selection is the essential tool for understanding the general ev...

Multicultural Commercial Websites: When Translating Might Not Be Enough

The purchasing decisions of consumers on the Internet depend on the price and quality of the product, but also on a number of other factors that are clearly culture-related. One of these is the usability of the web site. The results of the present research show that the individually perceived user-friendliness increases when the web site was originally conceived in the native language of the us...

When Just One Is Enough

Information retrieval systems today scan large data spaces in response to the user's information need, returning lists of retrievables ordered by relevance 11]. In the general case, the tendency is to return as many relevant items as the system can locate. However, in situations where the retrievables are highly similar to one another, one just may be enough. In this extended abstract, we descr...

Might Dark Matter Be Actually Black?

There have been proposals that primordial black hole remnants (BHRs) are the dark matter, but the idea is somewhat vague. We argue here first that the generalized uncertainty principle (GUP) may prevent black holes from evaporating completely, in a similar way that the standard uncertainty principle prevents the hydrogen atom from collapsing. Secondly we note that the hybrid inflation model pro...
