Anti-doping researchers should conform to certain statistical standards from forensic science

Anti-doping is currently viewed as a forensic science. However, close examination shows that the statistical treatment of evidence is inconsistent with that view. Here it is insisted that anti-doping researchers should conform to certain statistical standards from forensic science.

Preparation of Tool Mark Standards with Jewelry Modeling Waxes

Abstract:  This paper presents how jewelry modeling waxes are used in the preparation of tool mark standards from exemplar tools. We have previously found that jewelry modeling waxes are ideal for preparing test tool marks from exemplar tools. In this study, simple methods and techniques are offered for the replication of accurate, highly detailed tool mark standards with jewelry modeling waxes. The techniques described here demonstrate the conditioning and proper use of jewelry modeling wax in the production of tool mark standards. The application of each test tool's working surface to a piece of the appropriate wax in a manner consistent with the tool's design is clearly illustrated. The resulting tool mark standards are exact, highly detailed, 1:1, negative impressions of the exemplar tool's working surface. These wax models have a long shelf life and are suitable for use in microscopic examination comparison of questioned and known tool marks.     

Racial Dynamics of Subprime Mortgage Lending at the Peak

Subprime mortgage lending in the early 2000s was a leading cause of the Great Recession. From 2003 to 2006, subprime loans jumped from 7.6% of the mortgage market to 20.1%, with black and Latino borrowers receiving a disproportionate share. This article leveraged the Home Mortgage Disclosure Act data and multinomial regression to model home-purchase mortgage lending in 2006, the peak of the housing boom. The findings expose a complicated story of race and income. Consistent with previous research, blacks and Latinos were more likely and Asians less likely to receive subprime loans than whites were. Income was positively associated with receipt of subprime loans for minorities, whereas the opposite was true for whites. When expensive (jumbo) loans were excluded from the sample, regressions found an even stronger, positive association between income and subprime likelihood for minorities, supporting the theory that wealthier minorities were targeted for subprime loans when they could have qualified for prime loans. This finding also provides another example of an aspect of American life in which minorities are unable to leverage higher class position in the same way as whites are. Contrary to previous research, model estimates did not find that borrowers paid a penalty (in increased likelihood of subprime outcome) for buying homes in minority communities.     

A plea for thresholds, i.e., maximal allowed levels for prohibited substances, to prevent questionable doping convictions

With the development of highly sensitive drug testing technologies that can detect a minute quantity of a prohibited substance in an athlete's body, accidental contamination through contact with publicly circulated materials can more readily result in a "positive" reading. To discharge the burden of a positive finding, the athlete must show the "factual circumstances" in which the prohibited substance entered his/her system. In cases of accidental contamination, the athlete generally cannot even know how it occurred, as there are many known and unknown possible sources of contamination. When an athlete does give an account, it cannot generally be proven or disproven. Outside the realm of sports anti-doping, the use of scientifically established thresholds for drug testing is standard practice. Basic logic dictates that thresholds would enable one to differentiate between relevant and irrelevant amounts in the context of a possible sports doping offence. Such a threshold should be functionally motivated, i.e., enable the differentiation between relevant and irrelevant quantities in the context of a possible doping offence, rather than based on instrument performance limits.
