Claims fraud is an increasingly vexing problem confronting the insurance industry. In this empirical study, we apply Kohonen's Self-Organizing Feature Map to classify automobile bodily injury (BI) claims by the degree of fraud suspicion. Feed forward neural networks and a back propagation algorithm are used to investigate the validity of the Feature Map approach. Comparative experiments illustr...

In our article (Weisberg & Gopnik, 2013), we construct a unifying theory of imaginative processes, in which counterfactuals and pretend games share an underlying cognitive capacity. This theory allows us to explain why children pretend, why they create fantastical pretend worlds, and how pretend play and counterfactual reasoning can help children to learn about the causal structure of reality. ...

A patient arrives alert and conscious to the Trauma Center at the Dartmouth Hitchcock Medical Center (DHMC). As an adult Hispanic woman with no preexisting psychological condition, she is unremarkable save for the fact that she has survived an acute life-threatening event. She is interviewed upon arrival and administered a series of tests to quantitatively assess her injuries. This process is t...

Methods for estimating and testing the fit of linear models, such as regression models with fixed regressor (explanatory) variables, or general models for linear structural relations, are well understood for the analysis of a simple random sample, or for the simultaneous analysis of random samples from distinct populations (see, for example, JSreskog & S6rbom, 1979; McArdle & McDonald, 1984). T...

We present a study of the gravitational time delay of arrival of signals from binary pulsar systems with rotating black hole companions. In particular, we investigate the strength of this effect (Shapiro delay) as a function of the inclination, eccentricity and period of the orbit, as well as the mass and angular momentum of the black hole. This study is based on direct numerical integration of...

Almost a decade ago I wrote an article with the same title as this. It focused on the physical properties of the Tiny-Scale Atomic Structure (TSAS) as discrete structures of the Cold Neutral Medium (CNM). To be observable, tiny discrete structures that don’t grossly violate pressure equilibrium need two attributes: low temperatures and geometrical anisotropy. Here I update that article. I discu...

Research on the existence of cognitive maps and on the cognitive processes that support effective navigation has often focused on functioning across individuals. However, there are pronounced individual differences in navigation proficiency, which need to be explained and which can illuminate our understanding of cognitive maps and effective navigation. Using a virtual environment involving 2 r...

We are entering an age in which knowledge about the brain in general, and the mind in particular,1 will inform policy. Genetics already informs policy, which is curious since advances in genetics are significantly more recent than advances in the brain sciences, including cognitive science, and the distance between genes and behavior is long and complex, often making poor predictions from the f...

Generalized least-squares (GLS ) regression extends ordinary least-squares (OLS) estimation of the normal linear model by providing for possibly unequal error variances and for correlations between different errors. A common application of GLS estimation is to time-series regression, in which it is generally implausible to assume that errors are independent. This appendix to Fox and Weisberg (2...

This paper commences by outlining notions of creativity before examining the role of emergence in creative design. Various process models of emergence are presented; these are based on notions of additive and substitutive variables resulting in additive and substitutive schemas. Frameworks for both representation and process for a computational model of creative design are presented. The repres...
