Ecological Inference and Entropy-Maximizing: An Alternative Estimation Procedure for Split-Ticket Voting

Publication of King's A Solution to the Ecological InferenceProblem has rekindled interest in the estimation of unknowncell values in two- and three-dimensional matrices from knowledgeof the marginal sums. This paper outlines an entropy-maximizing(EM) procedure which employs more constraints than King's EImethod and produces mathematical rather than statistical procedures:the estimates are maximum-likelihood values. The mathematicsare outlined, and the procedure's use illustrated with a studyof ticket-splitting at New Zealand's first (1996) general electionusing the mixed-member proportional representation system, forwhich official figures provide a check against the EM estimateof the number voting a straight party ticket in each constituency.     

Medical examination of sexually abused children: medico-legal value

The Department of Forensic Medicine (forensic pathology and clinical forensic medicine), Aarhus, Jutland, Denmark, performs examinations of children suspected to have been sexually abused when reported to and requested by the police in Jutland, Denmark. Jutland covers an area of 210,000 km2 with about 300,000 inhabitants in Aarhus. A colposcope initially equipped with an Olympus camera, but now with a video camera attached has been used since 1994. Since 1994 the department has performed more than 100 examinations of children suspected of having been sexually abused. A preliminary study was taken to evaluate all cases from 1995 including the legal outcome. RESULTS: The material included 34 cases with three boys, mean age 11 years, and 31 girls, mean age 8 years, at the time of the examination. The sexual abuse events were fondling including penetration of the vagina, vaginal (14), anal (7), and oral (5) intercourse as well as cunnilingus and nontouching abuses. The medical examination was most often performed more than a week after the abuse. The examination revealed normal findings in 23 cases, nonspecific findings including erytherma in 13 cases, and in only one child was a traumatic lesion with rupture of the hymen seen. The perpetrators were above 25 years of ane and were family members or someone known to the child. Nine perpetrators were convicted at court, of whom three admitted having abused the child. CONCLUSION: A medical examination in cases of sexual child abuse seldom provides a legal proof of sexual abuse. The most important is the story told by the child. Therefore, the examination is a supplement which may support or remain neutral to the story told by the child.     

An attempt to detect “pregnancy susceptibility” in indigent adolescent girls

Programs for widespread dissemination of birth control information and devices among adolescents are subject to strong resistance from many groups and may be ineffective anyway. An alternative approach to reducing the alarming frequency of unplanned pregnancy among unmarried adolescents might be group or individual counseling for those most susceptible, to unplanned pregnancies. Accurate identification would be necessary to implement this alternative. Developed in this paper is an inferential strategy for identifying in well-defined groups unmarried adolescents who seem susceptible. When carefully evaluated, an inferential strategy, based, on several concepts from Bayesian inference theory, appears remarkably accurate as a means of identification.
