Utilizing a magnetic locator to search for buried firearms and miscellaneous weapons at a controlled research site

Forensic personnel generally use basic all-metal detectors for weapon searches because of their ease of use and cost efficiency. For ferromagnetic targets, an alternative easy to use and low-cost geophysical tool is a magnetic locator. The following study was designed to demonstrate the effectiveness of a common, commercially available magnetic locator in forensic weapon searches by determining the maximum depth of detection for 32 metallic forensic targets and testing the effects of metallic composition on detection. Maximum depth of detection was determined for 16 decommissioned street-level firearms, six pieces of assorted scrap metals, and 10 blunt or bladed weapons by burying each target at 5-cm intervals until the weapons were no longer detected. As expected, only ferromagnetic items were detected; weapons containing both ferromagnetic and nonferromagnetic components were generally detected to shallower depths. Overall, the magnetic locator can be a useful addition to weapon searches involving buried ferromagnetic weapons.     

Survival of anesthetized Sus scrofa after cycling (7-second on/3-second off) exposures to an electronic control device for 3 minutes

Electronic control devices (ECDs) may eventually be deployed by the military in a manner resulting in longer exposures than those encountered during law-enforcement operations. In a previous study, 18 repeated cycling (5-second on/5-second off) exposures (within a 3-minute period) of anesthetized swine to an ECD (TASER International's Advanced TASER X26 device) resulted in leg muscle contraction, acidosis, and increases in blood electrolytes. In the current study, experiments were performed to examine effects of exposures to a different cycling rate (7-second on/3-second off), from a modified X26 ECD, on 10 swine (Sus scrofa), maintained on propofol anesthesia. In contrast with the previous study, a large number of animals (6/10) died immediately after the exposures. There were no major differences in pre-exposure blood factors from survivors versus nonsurvivors, with the exception of hematocrit and 2 isoenzymes of lactate dehydrogenase. It is doubtful that these factors would be useful in predicting survival after ECD exposure. Blood pH was significantly decreased after exposure, but (in animals that survived) subsequently returned to baseline levels. On the basis of the overall survival rate, further development of useful ECDs (for long-term incapacitation during military operations) may require consideration of longer pauses between repeated exposures over a 3-minute period.     

Thermal Imaging as a Lie Detection Tool at Airports

We tested the accuracy of thermal imaging as a lie detection tool in airport screening. Fifty-one passengers in an international airport departure hall told the truth or lied about their forthcoming trip in an interview. Their skin temperature was recorded via a thermal imaging camera. Liars’ skin temperature rose significantly during the interview, whereas truth tellers’ skin temperature remained constant. On the basis of these different patterns, 64% of truth tellers and 69% of liars were classified correctly. The interviewers made veracity judgements independently from the thermal recordings. The interviewers outperformed the thermal recordings and classified 72% of truth tellers and 77% of liars correctly. Accuracy rates based on the combination of thermal imaging scores and interviewers’ judgements were the same as accuracy rates based on interviewers’ judgements alone. Implications of the findings for the suitability of thermal imaging as a lie detection tool in airports are discussed.     

Assessing the Overlap in Dating Violence Perpetration and Victimization among South Korean College Students: The Influence of Social Learning and Self-Control

Research has recently begun to identify an overlap of involvement in offending and victimization and a shared commonality of risk factors for both outcomes. Despite this growing body of evidence, this research has yet to have been extended to dating violence in general and in cross cultural samples specifically. Recognizing these gaps in the literature, the current study examines the correlation between psychological and physical dating violence perpetration and victimization among a large sample of South Korean college students. Results from a series of bivariate probit models suggest that there is a strong degree of overlap between dating violence perpetration and victimization and that social learning theory and self-control theory cannot explain away the overlap. Study limitations and implications are also discussed.     

Autocracy and coups d’etat

In this paper I first briefly survey Tullock’s contributions to the study of autocracy and coups d’etat. Tullock’s analysis of the coup d’etat is insightful. He suggested that those at the top could control those at the bottom with a proper system of incentive payments. Here I expand on that idea by asking the reverse question, not what keeps those at the bottom from rebelling, but what keeps those at the top from looting the regime? I begin by noting that shareholders of the modern widely held corporation face a similar problem: what keeps the CEO from looting the company when the market for corporate control is flawed, shareholders are too weak to exercise discipline, and the board is in the CEO’s pocket? I suggest the answer is provided by “internal governance”: the old need the young for good performance. I explain the financial crisis of 2008 as in part the result of the failure of this mechanism. I also explain the success of modern China this way: The Communist Party facilitates growth because its structure provides a way for superiors (the “old”) to trade with subordinates (the “young”). I have also expanded on Tullock’s analysis to ask what conditions might prevent the dictator from implementing his solution to the coup d’etat problem, thus explaining why coups d’etats actually occur. The basic reason is the weakness of the state. Japanese history provides two interesting illustrations of this: first the Tokugawa regime, where the people were over-controlled, and second, the Meiji constitution, implemented after the fall of the Tokugawa state. The Japanese problem after Meiji was that the military (the young) had no incentive to offer their loyalty to the old (the civilian regime), so the young acted on their own. The problem was the reverse of the Tokugawa regime’s: the Meiji constitution left the bottom with too much control over the top. There was no formal coup d’etat but a number of coup attempts were made and de facto the military increasingly constituted a state within a state. This reversal of authority apparently continued down the chain of command, ultimately with tragic consequences, most notably the invasion of Pearl Harbor.     

Diacetylene copolymers for fingermark development

In 1979, Miller and Patel showed that a solution containing two diacetylene monomers, 2,4-hexadiyne-1,6-bis(phenylurethane) (HDDPU) and 2,4-hexadiyne-1,6-bis(p-chlorophenylurethane) (HDDCPU) could be used to develop latent fingermarks on a non-porous surface. In the current work, the same mixture (HDDPU:HDDCPU=10:1, in acetone solution) was used to develop fingermarks on a wide variety of surfaces, both non-porous and porous, including paper. An airbrush system was optimized for the application of the reagent solution. Once the solution evaporates on a surface, the monomers co-crystallize in different ways, depending upon a number of factors, including the surface residue. "Active" co-crystallization leads (with heat or radiation) to the formation of purple polymer, while "inactive" crystallization results in a non-polymerizable white deposit. Fingermark contrast was achieved as a result of active co-crystallization (giving purple polymer) in either the ridges or the furrows, depending upon the surface and other factors. A general observation (supported by spot tests with linseed oil, salt and amino acid solutions) was that on paper, oily materials are more likely to lead to the formation of the purple polymer, while the presence of water inhibits polymerization. However, these observations are not consistent across all other substrates. It is hypothesized that water disrupts hydrogen bonding between diacetylene molecules, and thus prevents the topochemical polymerization of the diacetylenes, which occurs in the solid state between favourably aligned monomers. An interesting observation was the development of fingermarks deposited on paper that had already been treated with the diacetylene reagent.     

Validation of LUCIO-Direct-ELISA kits for the detection of drugs of abuse in urine: application to the new German driving licence re-granting guidelines

LUCIO-Direct-enzyme linked immunosorbent assay (ELISA) tests were validated for the screening of drugs of abuse cannabis, opiates, amphetamines and cocaine in urine for the new German medical and psychological assessment (MPA) guidelines with subsequent gas chromatographic-mass spectrometric (GC-MS) confirmation. The screening cut-offs corresponding to 10 ng/mL 11-nor-delta-9-tetrahydrocannabinol-9-carboxylic acid (THC-COOH), 50 ng/mL amphetamine, 25 ng/mL morphine and codeine and 30 ng/mL benzoylecgonine were chosen at the point where the number of false negatives was lower than 1%. Due to their accuracy, ease of use and rapid analysis, these ELISA tests are very promising for cases where a large proportion of the tests are expected to be negative such as for abstinence monitoring as part of the driving licence re-granting process.     

Does the truth come out in the writing? Scan as a lie detection tool

We tested the accuracy of Scientific Content Analysis (SCAN), a verbal lie detection tool that is used world-wide by federal law enforcement and military agencies. Sixty-one participants were requested to write down the truth, an outright lie or a concealment lie about activities they had just completed. The statements were coded with SCAN and with another verbal lie detection tool, Reality Monitoring (RM). RM discriminated significantly between truth tellers and outright liars and between truth tellers and concealment liars, whereas SCAN did not discriminate between truth tellers and either kind of liar. Implications of the findings for the suitability of SCAN as a lie detection tool are discussed.
