Policy Reforms Affecting Agricultural Incentives: Much Achieved, Much Still Needed

For decades, earnings from farming in many developing countries have been depressed by a pro-urban bias in own-country policies, as well as by governments of richer countries favoring their farmers with import barriers and subsidies. Both sets of policies reduce national and global economic welfare and inhibit agricultural trade and economic growth. They almost certainly add to inequality and p...

How Much Face Information Is Needed?

Multimodal 2D+3D face biometrics commonly report that performance improves relative to that of a single modality. Complete 2D and 3D data can be available during training because they are acquired in a controlled scenario. However, in the evaluation scenario, only partial 2D and 3D data can be acquired and hence available for recognition. In this paper we present experimental results that deter...

Traditionally, the U.S. Army has assigned its units to specific geographic locations, and then staffed those units by rotating individual soldiers into them throughout the year. Starting with the operations in Bosnia and Kosovo, however, entire units were deployed and subsequently replaced by other units—a practice that contrasted starkly with the individual replacement system. Unit replacement...

How Much Randomness Is Needed for Statistics?

In algorithmic randomness, when one wants to define a randomness notion with respect to some non-computable measure λ, a choice needs to be made. One approach is to allow randomness tests to access the measure λ as an oracle (which we call the “classical approach”). The other approach is the opposite one, where the randomness tests are completely effective and do not have access to the informat...
