Height and seriousness of crime in XYY men.
The case histories of XYY males in two security settings were ranked by degree of seriousness of crime. The correlations of these scores with height were either zero (for data of Daly with the history of the propositus excluded) or positive (for data of Jacobs et al., P less than 0.05). For both studies, the results were contrary to the expectation of negative correlation which would be found i...
متن کاملOn the Average Height of b-Balanced Ordered Trees
An ordered tree with height h is b-balanced if all its leaves have a level l with h − b <= l <= h, where at least one leaf has a level equal to h − b. For large n, we shall compute asymptotic equivalents to the number of all b-balanced ordered trees with n nodes and of all such trees with height h. Furthermore, assuming that all b-balanced ordered trees with n nodes are equally likely, we shall...
متن کاملComputing the Average Height in Trace Monoids
The height of a trace is the height of the corresponding heap of pieces in Viennot's representation, or equivalently the number of factors in its Cartier-Foata decomposition. Let h(t) and jtj stand respectively for the height and the length of a trace t. We prove that the bivariate commutative series P t x h(t) y jtj is rational, and we give a nite representation of it. We use this result to ob...
متن کاملIndividual Wave Height from Sar
Safety of shipping is an ever growing concern. In a summary on shipping safety Douglas Faulkner investigates the causes of shipping casualties [1] and concludes that the number of unexplained accidents are far too high in comparison to other means of transport. From various sources, including insurers data over 30% of the casualties are due to bad weather ( a fact that ships should be able to c...
متن کاملIndividual Heterogeneity and Average Welfare∗
Individual heterogeneity is an important source of variation in demand. Allowing for general heterogeneity is needed for correct welfare comparisons. We consider general heterogenous demand where preferences and linear budget sets are statistically independent. We find that the dimension of heterogeneity and the individual demand functions are not identified. We also find that the exact consume...
