Fragmentation and Old Evidence

Evidence based sperm DNA fragmentation

Old and New Parton Distribution and Fragmentation Functions * )

A short review of problems with parton distribution functions in nucleons, non-polarized and polarized, is given. The main part is devoted to the transversity distribution its possible measurement and its first experimental probe via spin asymmetry in semi-inclusive DIS. It is argued that the proton transversity distribution could be successfully measured in future DIS experiments with longitud...

Becoming Oldest-old: Evidence

The ' Old Evidence ' Problem

This paper offers an answer to Glymour's 'old evidence' problem for Bayesian confirmation theory, and assesses some of the objections, in particular those recently aired by Chihara, that have been brought against that answer. The paper argues that these objections are easily dissolved, and goes on to show how the answer it proposes yields an intuitively satisfactory analysis of a problem recent...

Social Fragmentation, Public Goods and Elections: Evidence from China∗

This study examines how the economic e ects of elections in rural China depend on voter heterogeneity, as captured by religious fractionalization. We rst document religious composition and the introduction of village-level elections for a nearly nationally representative sample of over two hundred villages. Then, we examine the interaction e ect of heterogeneity and the introduction of election...
