Time Does Not Help Orangutans Pongo abelii Solve Physical Problems

Many questions in animal intelligence and cognition research are challenging. One challenge is to identify mechanisms underlying reasoning in experiments. Here, we provide a way to design such tests in non-human animals. We know from research in skill acquisition in humans that reasoning and thinking can take time because some problems are processed in multiple steps before a solution is reache...

Does Immigration Grease the Wheels

MOST STUDIES OF the economic impact of immigration are motivated by the desire to understand how immigrants affect various dimensions of economic status in the population of the host country. This motivation explains the persistent interest in determining whether immigrants “take jobs away” from native workers, as well as the attention paid to measuring the fiscal impact that immigration inevit...

Fundamental Problems in Comparative Phonetics and Phonology: Does Upsid Help to Solve Them?

The approach to phonological comparison adopted in UPSID as well as other studies fails to recognize the abstract nature of even the most phonetically based definition of a phonemic system. Phonemes receive a simple phonetic translation based on one allophone. Phonological comparison is therefore carried out using no more than arbitrary selections of the phonetics of the languages involved. Pho...

Learning to Solve Constraint Problems

This paper explains why learning to solve constraint problems is so difficult, and describes a set of methods that has been effective on a broad variety of problem classes. The primary focus is on learning an effective search algorithm as a weighted subset of ordering heuristics. Experiments show the impact of several novel techniques on a variety of problems. When a planning problem is cast as...
