Recidivism as a feedback process: An analytical model and empirical validation

A feedback model of the criminal justice system (CJS) incorporates the continuing input of people arrested for the first time (virgin arrests) and the recycling of individuals with prior arrests (recidivists). Such a model is needed to enable CJS planners to assess the impact of possible actions on the future arrests and system workloads. Using an empirically determined estimate of the number of virgin arrests in the U.S. as input to a feedback model of the CJS, recidivism parameters, probability of rearrest, and average time between arrests were estimated by matching the output of the model to the total arrests in the U.S. in the period 1960–70. The average deviation between the model output and total U.S. arrests was minimized at less than 4% when the probability of rearrest is equal to 0.875 and the average time between arrests equal to 1.1. years. The relative sensitivity of total arrests to changes in virgin arrests and the probability of rearrest are also presented.     

Procedural fairness and work group responses to performance evaluation systems

In a variety of settings, procedures that permit predecision input by those affected by the decision in question have been found to have positive effects on fairness judgments, independent of the favorability of the decision. Two major models of the psychology of procedural justice make contrary predictions about whether repeated negative outcomes attenuate such input effects. If such attenuation occurs, it would lessen the applicability of procedural justice findings to some real-world settings, such as organizations, where procedures often provide repeated negative outcomes. The present laboratory investigation examined the procedural and distributive fairness justments produced by high- and low-input performance evaluation procedures under conditions of repeated negative outcomes. Thirty-five three-person groups of male undergraduates participated in a three-round competition. Groups either were or were not allowed to specify the relative weights to be given to two criteria used in evaluating their performance. All groups received negative outcomes on each of the three rounds. A second experimental factor varied whether or not the group learned after losing the second round that it could not possibly win the third and final round of the competition. Measures of procedural and distributive fairness showed that the high-input procedure led to judgments of greater procedural and distributive fairness across all three rounds. The input-based enhancement of fairness occurred regardless of whether reward was possible. The implications of these findings for theories of procedural justice and for applications of procedural justice to organizational settings are discussed.     

The experience of spermarche (the age of onset of sperm emission) among selected adolescent boys in Nigeria

This study examines the psychological experience of ejaculation among a sample of boys in relation to their emotional reactions to the experience, feelings of preparedness prior to the experience, pre- experience sources of information, and the extent of peer discussion after the experience. A total of 188 boys were selected for the study. The mean age of all the boys was 16.5 years (range 12–18 years). The results of the study revealed that the male experience of first ejaculation was not negative. The subjects indicated that they received more information from purely male sources, and they told friends about the experience after it happened. The level of preparedness of the subjects did not show any influence on the emotional responses of the subjects to first ejaculation. A simple ttest was used to compare subjects who were prepared and those not prepared for ejaculation on their emotional responses. The findings of the study were discussed and suggestion was made for further research.This research was supported by funds provided by the University of Ilorin Senate Research Committee.Also a member of the Counselling Association of Nigeria. Received master's degree in counselling psychology from the University of Ibadan, Nigeria, and doctorate degree in guidance and counselling from the University of Ilorin, Ilorin, Nigeria. Research interests include transition from childhood to adulthood, Correlates of pubertal problems in Nigerian adolescents, Adolescent sexuality (teenage prostitution, teenage pregnancy, etc.), child abuse and neglect, and developing psychological support programs for pubertal adolescents.
