The neuroendocrine effects of the TASER X26®: A brief report

IntroductionLaw enforcement officers use conducted electrical weapons (CEW) such as the TASER X26^® to control violently resistive subjects. There are no studies in the medical literature examining the effects of these weapons on the human stress response. This is the first study to compare the human stress response to conducted electrical weapons, oleoresin capsicum (O.C.), a cold-water tank immersion, and a defensive tactics drill.MethodsSubjects were randomized to one of the four interventions studied. Subjects received either a 5-s exposure from the TASER X26 CEW with the probes fired into the back from 7 ft, a 5-s spray of O.C., a skin and mucous membrane irritant, to the eyes, a 45-s exposure of the hand and forearm in a 0 °C cold water tank, or a 1-min defensive tactics drill.ResultsAlpha-amylase had the greatest increase from baseline at 10–15 min with the defensive tactics drill. Cortisol had the greatest increase at 15–20 min with O.C. Cortisol remained most elevated at 40–60 min in the defensive tactics drill group.ConclusionsOur preliminary data suggests that physical exertion during custodial arrest may be most activating of the human stress response, particularly the sympathetic–adrenal–medulla axis. This may suggest that techniques to limit the duration of this exertion may be the safest means to apprehend subjects, particularly those at high-risk for in-custody death. Conducted electrical weapons were not more activating of the human stress response than other uses of force.     

Political Orientation and Ideological Inconsistencies: (Dis)comfort with Value Tradeoffs

People are often inconsistent in the way they apply their values to their political beliefs (e.g., citing the value of life in opposing capital punishment while simultaneously supporting abortion rights). How do people confront such inconsistencies? Liberals were more likely to say that issues that could draw on several competing values were complex issues that required value tradeoffs, whereas conservatives were more likely to deny the comparability of the issues. We argue that this difference is rooted in the distinct ways that liberals and conservatives represent political issues. Additional evidence suggested that conservatives’ higher need for closure leads them to represent issues in terms of salient, accessible values. Although this may lead conservatives’ attitudes to be more situationally malleable under some circumstances, such shifts do serve to protect an absolutist approach to one’s moral values and help conservatives to deny the comparability of potentially inconsistent positions.     

From early Confucian texts to aged care in China and abroad today： The evolution of filial piety and its implications

Filial piety has remained a cornerstone of aged care in Chinese communities for at least 2,000 years. This paper reviews understandings and practices of filial piety in China and among Chinese migrants to western countries. Five dimensions of filial piety are considered： living arrangements, support, respect, ancestral worship and gender norms. Although the meaning of and practices associated with filial piety may have changed over time, the ideal of filial piety is still highly relevant to aged care in Chinese communities today.     

The use of error rates to predict and characterize the efficacy of presumptive field tests

From a forensic perspective, a presumptive test, one which indicates the presence or absence of a certain target material such as blood, is an invaluable tool. Among these tests, there are different specificities, sensitivities, and shelf lives. The accuracy of a test is an algebraic combination of the specificity and sensitivity of the test. Each test has limitations as given by its false positive and false negative rates. The aim of this study was to illustrate how the false positive and false negative rates are to be properly determined using a simulation study for the phenolphthalein test. New presumptive tests must be properly evaluated/validated through testing of commonly encountered household items and other potentially probative items usually found at crime scenes, however, the makeup of test sets must appropriately capture all error rates. In order to correctly use these results when the test is applied to an unknown sample recovered at a crime scene, the error rates cannot be applied directly to estimate whether or not the sample is actually the analyte of interest. In a validation study, the forensic scientist calculates the false positive rate as the p(Positive Reaction|Blood), whereas at the scene, the crime scene investigator wishes to determine the p(Blood|Positive Reaction). All crime scene investigators need to ensure that the conditional is not transposed when interpreting such results. Furthermore, this work provides a model for the assessment of a multiple test diagnostic system intended for investigators.     

A Simple Method of VNTR D1S80 Locus Allelic Ladder Construction for Capillary Electrophoresis‐based Genotyping

VNTR D1S80 locus genotyping has been largely replaced in forensics by STR. As the statute of limitations on murder cases was abolished in the Republic of Korea in July 2015, the demand for re‐analysis of DNA from unresolved murder cases has increased. The National Forensic Service includes several recorded D1S80 genotypes as crucial clues. Here, we re‐established the D1S80 analysis system using capillary electrophoresis and confirmed the reproducibility of the system by comparison with the genotypes of eight DNA samples that had been analyzed using PAGE in 2006. In addition, we created an allelic ladder via new methodology using flanking region sequences. A single DNA sample (K562) and seven primers were used for the new ladder, which contains 12 alleles. Although artificial owing to the use of the flanking region rather than repeat unit reduction, the method is rapid and simple, and could be applicable in any laboratory.     

Measuring the crime displacement and diffusion of benefit effects of open-street CCTV in South Korea

Crime prevention strategies are implemented to reduce the damage caused by crimes with CCTV (Closed-Circuit Television) being broadly accepted as one of the main strategies. However, along with CCTV's perceived high expectations as crime deterrent, there is also a growing controversy over CCTV's potentially unexpected limitations. For example, the crime displacement (the presence of CCTV will change the locations of crime and its total number will not change) and the diffusion effects of crime control benefits (the crime prevention effect of CCTV may filter through to neighboring areas) are the representative controversial issues. In this study, we aimed to verify the crime displacement and the diffusion of benefit of open-street CCTV by analyzing the crime tendencies empirically.Gwang Myeong City in Gyeonggi Province, South Korea was chosen to analyze the crime displacement using the WDQ (Weighted Displacement Quotient) which compares the crime tendency of a location with that of its neighboring areas. The results showed that the crime prevention effect of the CCTV was significant. The number of robberies and thefts in the areas with CCTV installed reduced by 47.4%, while the areas without CCTV showed practically no change in the number of crimes. The crime displacement caused by the CCTV was not either found or inconsequential, and the crime rates in the neighboring areas also decreased slightly. Of major cause for concern was the fact that CCTV was marginally effective in deterring violence and as such, there should be a more detailed scientific analysis of the pattern and type of crimes committed in an area where CCTV's are being installed.     

My Sassy Girl: a qualitative study of women's aggression in dating relationships in Beijing

The Korean film My Sassy Girl was very popular among young people in urban China in 2001. After the release of the movie, the new image of the "sassy girl" emerged in different media. This study uses the media image of the sassy girl as a stimulus material in interviews and focus groups to explore how young men and women make sense of women's aggression in dating relationships. This qualitative study is mainly based on two focus groups and in-depth interviews with 20 informants (13 female and 7 male). The study sheds light on how the competing and multilayered discourses in contemporary China regarding gender, love, and sex have left some space for young adults to justify women's aggression in dating relationships. We see how young adults in Beijing situate themselves within this set of social cultural discourses and make use of them to "do" their gender through their aggressive behavior and interactions with each other. New images of men and women are thereby created.     

River Politics: China's policies in the Mekong and the Brahmaputra in comparative perspective

China manages its transboundary rivers as a subset of its broader relations with other riparian states. This results in discernible differences in the way China approaches its international river systems. Although there is a limit to the extent of Chinese cooperation, in relative terms China is more cooperative in the Mekong than in the Brahmaputra. To China, Southeast Asian states are part of a hierarchical system where it stands at the apex. While problems exist, there are deep linkages between them, which help foster collaboration in the Mekong. India, which has greater power parity with China, is not part of China's hierarchical worldview. The territorial disputes and security dilemmas that characterize South Asian geopolitics further impede cooperation. Domestic considerations also impact on China's river policies. There is greater consensus among Chinese policymakers in managing the Mekong than the Brahmaputra, which explains the higher degree of clarity in Chinese policies towards the former compared to the latter.     

Injunctive Relief: But Let's Agree Not To Have It?

The ability of parties contractually to limit their right to seek injunctive relief has not often been judicially discussed. An interesting case from Singapore now appears to suggest that this is much more than a theoretical possibility. Some arguments can, however, be made to demonstrate that this is perhaps not the vista of opportunity over which some contract draughtsmen might rejoice, and care should be taken to ascertain the boundaries of the law, as explained in this note.     

Differentiation of coloured inks of inkjet printer cartridges by thin layer chromatography and high performance liquid chromatography

Document examiners are frequently asked to determine whether or not a colour printout has originated from a particular inkjet printer. The printer can rarely be identified unless some unique defects or irregularities of the printer are present on the printout. However, it is possible to decipher the make and/or model of the printer by comparing the ink-profile of the questioned printout with that of a seized inkjet printer cartridge or from one in a database. This paper presents an overview of a systematic approach to characterising and discriminating the inks of different inkjet printer cartridges using thin layer chromatography (TLC) and high pressure liquid chromatography (HPLC) with multi-wavelength ultra-violet/visible (UV/Vis) detection. Ink samples from 23 different inkjet printer cartridges (including originals and substitutes) of different brands and colour printouts, printed by known printers were examined with newly developed chromatographic methods. Subsequently, a database of the ink-profiles was generated. The methods provide a useful tool for discriminating coloured inks in inkjet printer cartridges of different brands.
