Systematic Bias of Radiocarbon Method

Systematic review of publication bias in studies on publication bias.

Introduction to Radiocarbon Determination by the Accelerator Mass Spectrometry Method

There are three principal isotopes of carbon which occur naturally C, C (both stable) and C (unstable or radioactive). These isotopes are present in the following amounts C 98.89%, C 1.11%, and C 0.00000000010%. Thus, one carbon-14 atom exists in nature for every 1,000,000,000,000 or (1 in a trillion) carbon-12 atoms in living material. The radiocarbon method is based on the rate of decay of th...

Systematic bias in OCR experiments

In this paper, we present the results from large-scale OCR experiments simulating several diierent groups of researchers performing the same test, but using slightly diierent equipment and procedures. We analyze the variance inherent in the sampled accuracy for each experiment, and the biases that exist in the experiments. We rst show that minor systematic (i.e., equipment and procedural) diier...

Introduction to Radiocarbon Determination by the Benzene Method

Note References below that are in red italics indicate published methodology works by M.A. Tamers Ph.D., D.Sc. and J.J. Stipp Ph.D., owners of BETA Analytic Inc., who were among the originators of the Benzene Method of Radiocarbon Dating. Between the two of them they have published well over 100 articles on geochronology and research related to the Benzene Method of Radiocarbon dating. An addit...

Party Identification: Efficient Heuristic of Systematic Bias?

Using a new dataset that takes advantage of a novel survey design, I accomplish a joint estimation of citizens’ policy views and legislators’ ideal points on the same scale. I analyze several important questions about people’s preferences, perceptions and voting behavior using the case of the 2004 presidential election. In contrast to many earlier works, I show that most people do in fact have ...
