AbstractLegal systems which triage protection to cultural relics based on a relic grading system have been adopted by several countries. This article examines the implementation of such a relic grading framework by the People's Republic of China. The current state of the law is summarized, and a recent criminal trial is described to illustrate the role the grading system plays within the law. The factors involved in defining the grades of cultural relics are then discussed in context of a cultural relic structural framework, with emphasis to both the state values that they serve and their ability to promote the objective of cultural property protection. The analysis highlights the problems and general considerations with the use of relic grading systems as a means to protect a large number of relics with finite resources.

For a variety of reasons, researchers and evidence-based clearinghouses synthesizing the results of multiple studies often have very few studies that are eligible for any given research question. This situation is less than optimal for meta-analysis as it is usually practiced, that is, by employing inverse variance weights, which allows more informative studies to contribute relatively more to the analysis. This article outlines the choices available for synthesis when there are few studies to synthesize. As background, we review the synthesis practices used in several projects done at the behest of governmental agencies and private foundations. We then discuss the strengths and limitations of different approaches to meta-analysis in a limited information environment. Using examples from the U.S. Department of Education's What Works Clearinghouse as case studies, we conclude with a discussion of Bayesian meta-analysis as a potential solution to the challenges encountered when attempting to draw inferences about the effectiveness of interventions from a small number of studies.
