Local authority performance indicators: Dousing the fire of campaigning consumers?

Much criticism has been levelled at the reliability of the Audit Commission's measures of local authority performance, but less attention has been paid to the reality of their empowering effect on consumer groups. This article reports on the impact of the policy on one consumer group, ALL MOD CONS, a national charity which campaigns for more and better public toilets. It argues that, far from empowering the group, the annual publication of performance indicators has diverted its energies and resources into disseminating the Audit Commision's statistics to their members and drawing misleading conclusions from them which risk undermining the group's credibility. The case raises questions about the role of performance indicators in the democratic process.     

Bounding the number of contributors to mixed DNA stains

We derive a simple inequality for the probability of observing a given DNA profile when assuming a fixed number of unknown persons have contributed to the mixed stain. We then show how this inequality can be used to obtain an upper bound for the number of unknown contributors needed to be considered.     

Terrorism and pork-barrel spending

The horrifying, tragic events of 9/11 made Americans aware of their vulnerability to terrorist attacks and triggered the creation of the Department of Homeland Security along with a substantial increase in federal spending to both thwart terrorist attacks and to increase our ability to respond to such emergencies. Much of this large increase in spending was in the form of direct transfers to states and cities through several grant programs. Homeland Security grants may be used for protection against terrorist activities, thereby enhancing public interests, or as wealth transfers to state and local governments, enhancing the reelection efforts of incumbents, and thus, private interests. Using 2004 per capita Homeland Security grant funding to states and their cities, we find that the funding formula used for some of the grant programs, which allocates almost 40% of the funds in some grant programs through a minimum percent to each state with the rest allocated based on population, means that per capita funding is related to electoral votes per capita, i.e., to the politics of Presidential re-election. However, the funding in other grant programs is also related to some of the dangers and vulnerabilities faced by states and their cities. Some of the variation in per capita grant allocations is also explained by the amount of airport traffic in the state and the state's population density, which are variables closely linked to the state's vulnerability to attack. Per capita Homeland Security grant allocations, however, do not seem to be related to the closeness of the 2000 presidential race.     

Comparison of gasolines using gas chromatography-mass spectrometry and target ion response

Gas chromatography-mass spectrometry was used to compare gasoline samples obtained from different sources based on the difference in amounts of certain components found in the headspace of gasoline using target response data. Many suspected arson cases involve comparing an ignitable liquid extracted from fire debris to a liquid found in a suspect's possession to determine if they could have had a common source. Various component ratios are proposed for determining if an unevaporated gasoline sample could have originated from the same source as an evaporated gasoline extracted from fire debris. Fifty and 75% evaporated gasoline samples were both found to contain similar ratios of certain components when compared with its unevaporated source gasoline. The results of the comparisons in this study demonstrate that for cases involving gasoline that has been evaporated up to 50% and extracted from pine, it is possible to eliminate comparison samples as originating from the same source. The results of the 75% comparisons suggest it may be possible to apply the same type of comparison to cases involving 75% evaporated gasoline.     

Further studies on spot tests and microcrystal tests for identification of cocaine

The presence of cocaine in illicit drug samples is still being determined in some laboratories using spot tests and microcrystal tests. Seventeen chemical species were tested using three different spot tests (Wagner, Marquis, and cobalt thiocyanate followed by stannous chloride reactions) and two microcrystal tests (gold chloride and platinic chloride) to determine whether the results could be differentiated from the results of these tests on cocaine. The data obtained indicated that nine of the 17 compounds gave results similar to those from cocaine using the three spot tests, but that the results from microcrystal testing allowed for differentiation of all nine compounds from cocaine.
