Police attitudes toward the utilization of civilian employees

Given that the disposition of patrol officers significantly affect the implementation of policy, the attitudes of patrolmen toward utilization of civilian personnel in two department differing in their rate of civilianization, were compared in this study. Based on a random sample, consisting of approximately 25% of the patrolmen from each department, attitudes toward each of three examined aspects of civilianzation were more positive among officers from the more civilianized department. After controlling for socioeconomic variables, it was also determined that younger, more educated and less experienced patrolmen, respectively, held motte positive belief about civilian usage.     

Strategies for eliciting and merging confidential social research data

This report presents, discusses and extends strategic models for representing the process of merging records from different sources when confidentiality of the records is required by law or custom. Examples and variations on the models cover simple situations, such as eliciting anonymous data from previously identified respondents, as well as more complex merge operations, such as merging files from different data archives and merging data under code linkage systems. The versatility and potential corruptibility of the models are also discussed.Supported by NSF Grants GI29843 and GS320-73X. Professors Eli Rubenstein, Donald T.

On the Robustness and Validity of Groups

In response to Nagin's comment on our paper, Methodological Sensitivities to Latent Class Analysis of Long-Term Criminal Trajectories, we reconsider the robustness and validity of group-based approaches to criminal trajectories and introduce additional issues for future research. We emphasize the limitations of typological approaches and the dangers of reifying the idea of distinct offender groupings for research and policy. We also clarify misunderstandings about the use of hierarchical linear models for studying trajectories of crime. Our basic conclusion is that methods in criminology need to be more tightly linked with theory.     

A re-examination of the MMPI-2 aggressiveness and immaturity indices in law enforcement screening

This study reports an analysis of Bartol's (1991) Immaturity Index and Hargrave and associates' (1988) Aggressiveness Index as a measure of police conduct. The correlations between the supervisory ratings and the Immaturity and Aggressiveness indices were examined for 1020 law enforcement officers. The results showed that Immaturity Index was related to termination for failure to complete training and insubordination. The Aggressiveness Index was related to a termination for failure to complete training and several other problematic police behaviors, but was not found to be specifically linked with acts of aggression. Implications for using these two indices in law enforcement selection are discussed.

Development of a finger printing device for use on a mobile robot

In this paper, we describe the development of a device for fuming fingerprints with cyanoacrylate (Super Glue) to enable police tactical units to obtain fingerprint evidence from suspicious packages using a remote-controlled robot. Through a series of initial experiments and preliminary designs, we show that effective cyanoacylate fuming requires sufficient heat, humidity, and airflow. This work led to the development of a final working prototype, called robot accessory for fuming fingerprint evidence (RAFFE), which is currently being field tested by the Calgary Police Service.
