The dynamics of unemployment and imprisonment in England and Wales, 1946–1985

This paper explores the dynamic relationship between unemployment and prison admissions in the English criminal justice system. First, by adopting econometric procedures designed to test between alternative forms of dynamic equilibria, it finds that there has been a steady-state growth rate in prison admissions and that unemployment growth has played an important role in determining that equilibrium. Second, by developing a behavioral model of judicial expectations, it argues that judges have used their expectations as heuristic devices for simplifying sentencing decisions and that the unanticipated changes in unemployment have played a key role in determining changes in sentencing patterns. Due to individualized sentencing practices characteristic of English judges, unemployment plays a much larger role in determining prison sentences than warranted under Anglo-American legal traditions.     

Reducing the cost of resolving intellectual property disputes

An important reason why intellectual property is far less effective for generating innovation than it could be is the excessively high cost of resolving disputes. This largely reflects the use of ordinary court arrangements to determine what are essentially technical issues. Compulsory expert arbitration, with legal aid for the party that doesnot appeal to the court from a ruling, is proposed as an alternative. A full-scale working model of such a system is shown to exist in the interference procedure of the United States Patent and Trademark Office. That no more than 4 percent of court appeals from decisions in this are even partially successful augurs well for the potential value of the arrangements proposed.     

A discriminant function analysis of deciduous teeth to determine sex

Studies of deciduous teeth have concluded that crown size differences in these teeth between males and females are not reliable sex discriminators, in contrast to such differences in permanent teeth. This study measured the mesiodistal and faciolingual crown diameters of all deciduous teeth, as well as those of the permanent first molars, of 162 children from the Burlington Orthodontic Growth Study, conducted earlier in Burlington, Ontario, Canada. All 40 deciduous tooth diameters (20 mesiolingual and 20 faciolingual) were significantly different between the sexes, as were the permanent tooth diameters. Using three to five measurements of deciduous teeth, discriminant analyses of several samplings of these children produced discriminant functions in which 76 to 90% of the holdout samples were correctly classified by sex. Combinations of deciduous and permanent measurements were used to classify 83 to 85% of the holdout samples correctly. When compared with published data on other sample populations, the Burlington group is the most dimorphic for deciduous teeth and is within the range of permanent tooth dimorphisms of other populations. The level of classification accuracy, when using discriminant analysis of the deciduous teeth, can approach the accuracy levels of analysis using the permanent teeth.     

Teaching through the use of games and simulations

This paper describes the use of games and simulations in teaching criminal justice students and those in the related social sciences. The authors have utilized a two-week interim session (following the spring semester) to use this approach in illustrating a wide variety of concepts such as political power, conflict, cooperation and negotiation as applied to criminal justice and other governmental agencies. Two types of teaching tools--small group board games and large group simulations--have been utilized. While the interim class sessions run two and one-half hours each, many of the games and simulations are adaptable to shorter time periods or multiple class periods and, thus, are useful teaching devices for regular school terms¹.
