The reasons for the development and collapse of Maya civilization remain controversial and historical events carved on stone monuments throughout this region provide a remarkable source of data about the rise and fall of these complex polities. Use of these records depends on correlating the Maya and European calendars so that they can be compared with climate and environmental datasets. Correl...
In one of their seminal articles on allowable sequences, Goodman and Pollack gave combinatorial generalizations for three problems in discrete geometry, which being the Dirac conjecture. According to this conjecture, any set n noncollinear points plane has a point incident at least cn connecting lines determined by set. The notion sequences permutations provides natural setting analyzing these ...
Most biogeographers will probably agree with Ebach et al. (2003) that an essential goal of biogeography is to ‘discover why organisms are distributed the way they are today’ (citing Platnick & Nelson, 1978). Moreover, many also agree that this is achieved by uncovering ‘the patterns of spatial distribution attained by life on earth and the means by which these distributions were achieved’ (citi...
The Nelson–Aalen estimator is a nonparametric estimator which may be used to estimate the cumulative hazard rate function from censored survival data (see Survival Distributions and Their Characteristics). Since no distributional assumptions are needed, one important use of the estimator is to check graphically the fit of parametric models, and this is the reason why it was originally introduce...
On December 23, 2015, Alfred Goodman Gilman died peacefully at home after a long battle with pancreatic cancer. Though Al was one of the great scientific minds of the past 50 years and is best known for his discovery of guanine nucleotide-binding regulatory proteins (G proteins), anyone who trained or worked closely with Al knew him as much more than that. His greatness extended equally to scie...
In March 2003, Psychological Science published an article by Goodman and colleagues examining memory for prior childhood abuse in a sample of adolescents and young adults who as children had been the victims of childhood abuse that lead to criminal prosecution. At the time of the prosecution cases, the children in this study had been part of a research project conducted by Goodman and colleague...
