Examining GPS monitoring alerts triggered by sex offenders: The divergence of legislative goals and practical application in community corrections

Purpose

Legislative mandates that require GPS monitoring of offenders add to the existing logistical complexities of community supervision. Challenges in implementing GPS policies and practices are heightened by the lack of sound empirical research. Studies examining the relationships between GPS monitoring of sex offenders in the community and the legislative goals of public safety, deterrence, and cost effectiveness are virtually nonexistent. To begin to address this gap in the literature, this study examines the impact of a statutorily-based GPS monitoring program for adult sex offenders convicted of dangerous crimes against children and placed under community supervision.

Method

Official offender generated alert data for DCAC Sex Offenders in Maricopa County, AZ are examined from the time of legislative mandate for a subsequent two year period.

Results

Analyses highlight the significant number of equipment related alerts triggered by a loss of satellite signal for offenders under GPS monitoring as a key concern as well as a significant increase in officer workload as a result.

Conclusions

A divergence between legislative goals and practical application of mandated GPS monitoring programs exists. GPS technology is far more limited than anticipated and should be viewed as a tool rather than depended upon as a control mechanism.     

MI1(b) and the origins of British diplomatic cryptanalysis

The War Office's First World War cryptanalytic bureau MI1(b) has been severely overshadowed by its more glamorous equivalent in the Admiralty, ‘Room 40’. In particular its diplomatic decryption work has gone completely unnoticed; yet this was its main activity, and it contributed more than did Room 40 to their common successor, the Government Code and Cypher School (GC&CS). This article, drawing on the past decade's releases of GC&CS archives, traces the development of MI1(b)'s diplomatic work, disentangles its achievements from those of its better-known naval colleague, describes how the two organizations were merged to become GC&CS, and suggests why MI1(b)'s achievements were so quickly forgotten.     

The Policy Constraints of Deficit Reduction: President Clinton's 1995 Budget

The federal budgeting process is now limited by deficit reduction policy constraints. This article examines the FY 1995 budget requests within the context of long term budget trends, changes in the federal budget process, and the recently established political and fiscal budget constraints. It further examines enactment of the Omnibus Budget Enforcement Act of 1993, the policy changes it contained, and its further tinkering with the process of budgeting. Finally the article evaluates the first budgeting process of the Clinton administration and their initiatives in deficit reduction following these policy constraints.     

High prevalence of 6-acetylmorphine in morphine-positive oral fluid specimens

Identification of 6-acetylmorphine, a specific metabolite of heroin, is considered to be definitive evidence of heroin use. Although 6-acetylmorphine has been identified in oral fluid following controlled heroin administration, no prevalence data is available for oral fluid specimens collected in the workplace. We evaluated the prevalence of positive test results for 6-acetylmorphine in 77,218 oral fluid specimens collected over a 10-month period (January-October 2001) from private workplace testing programs. Specimens were analyzed by Intercept immunoassay (cutoff concentration=30 ng/ml) and confirmed by GC-MS-MS (cutoff concentrations=30 ng/ml for morphine and codeine, and 3 ng/ml for 6-acetylmorphine). Only morphine-positive oral fluid specimens were tested by GC-MS-MS for 6-acetylmorphine. A total of 48 confirmed positive morphine results were identified. An additional 107 specimens were confirmed for codeine only. Of the 48 morphine-positive specimens, 32 (66.7%) specimens were positive for 6-acetylmorphine. Mean concentrations (+/-S.E.M.) of morphine, 6-acetylmorphine and codeine in the 32 specimens were 755+/-201, 416+/-168 and 196+/-36 ng/ml, respectively. Concentrations of 6-acetylmorphine in oral fluid ranged from 3 to 4095 ng/ml. The mean ratio (+/-S.E.M.) of 6-acetylmorphine/morphine was 0.33+/-0.06. It is suggested that, based on controlled dose studies of heroin administration, ratios >1 of 6-acetylmorphine/morphine in oral fluid are consistent with heroin use within the last hour before specimen collection. The confirmation of 6-acetylmorphine in 66.7% of morphine-positive oral fluid specimens indicates that oral fluid testing for opioids may offer advantages over urine in workplace drug testing programs and in testing drugged drivers for recent heroin use.
