The collateral consequences of GPS-LED supervision in hot spots policing

Hot spots policing is popular, yet little is known about officer receptivity to the tactic and its impact on internal procedural justice, organizational commitment, and self-legitimacy. The nature of the tactic means that officers must relinquish their discretionary powers so that they can be directed to crime and disorder locations at specific times and for regimented durations. This loss of ‘spatiotemporal autonomy’ is exacerbated by technological tracking devices. We examined the receptivity of British officers to hot spots patrols, where the deployment was tracked with individual GPS trackers, compared to parallel patrols without hot spots policing or tracking. In contrast to the comparison group, officers in hot spots disliked the routinization of their shifts; regimented patrols were detrimental for internal procedural justice and organizational commitment. The ramifications of the introduction of GPS-enabled systems include certain tracking of officers and their compliance, such as a Taylorist time and motion study. While hot spots policing remains an effective tactic, questions about sustainability may be raised if officers’ expectations, attitudes and receptivity are not managed.     

Optimisation of choline testing using Florence Iodine reagent,including comparative sensitivity and specificity with PSA and AP tests

The detection of semen in forensic science is essential in cases of sexual assault but can be problematic in the absence of spermatozoa. Choline is known to occur in high concentrations in seminal fluid and the Florence Iodine test for its detection has been used in forensic science for many years, however very little is documented regarding its sensitivity and specificity in forensic casework. This paper describes the optimisation of the choline Florence Iodine test (FI) and investigates the sensitivity and specificity of the test against different body fluids, food and drink substances, cleaning products and laboratory chemicals. Comparative testing against Acid Phosphatase (AP) and Prostate Specific Antigen (PSA Seratec®) tests is described and shows that the FI test has greater specificity than the PSA test which cross reacts with a number of body fluids.     

Forensic identification of urine using the DMAC test: a method validation study

Forensic scientists may sometimes be asked to identify the presence of urine in cases such as harassment, rape or murder. One popular presumptive test method uses para-dimethylaminocinnamaldehyde (DMAC), favoured because it is simple, rapid and safe. This paper confirms that DMAC reacts with urea rather than creatinine, ammonia or uric acid. Sensitivity studies found that the 0.1% w/v DMAC solution currently used for urine identification detects levels of urea found in other body fluids, potentially resulting in false positives. A 0.05% w/v solution was found to be more appropriate in terms of sensitivity to urea however the test is still not specific for urine, giving positive reactions with a number of body fluids (saliva, semen, sweat and vaginal material) and other substances (foot lotion, hair removal cream and broccoli).     

Strong Poets and Utopia: Rorty's Liberalism, Dewey and Democracy

Richard Rorty is one of the most controversial philosophers today. He argues, among other things, that philosophy should be replaced by literary writing and that it has nothing to say to politics. Yet his own more recent writing has been more and more about political issues. This article focuses upon the inconsistency of his politics with the philosophical influence which he has consistently identified as the strongest on his writings; that of John Dewey. At the root of this incompatibility lies the failure of his theoretical project to carry over his synthesis between Deweyan pragmatism and Nietzschean poststructuralism into the realm of politics.
