Disconnection and resistance: anti-terrorism and citizenship in the UK

The corroding impacts of anti-terrorism measures on citizenship have been much discussed in recent years. Drawing on qualitative research from the UK, this article argues that citizens do indeed frequently feel that aspects of citizenship – such as rights, duties, identity claims and the ability to participate in the public sphere – have been significantly dampened by developments in this policy area. At the same time, however, participants in our research also articulated a number of strategies through which they or others have sought to resist the logics, exercise and impacts of anti-terrorism powers. These included voicing explicit opposition to particular measures, resisting ‘outsider’ or ‘victim’ subject positions, and a refusal to withdraw from established forms of political engagement. Whilst such resistance should not be overstated, we argue that these strategies emphasise the co-constitutive rather than linear relationship between public policy and citizenship. Anti-terrorism powers do indeed impact upon citizenship claims, for instance in the curtailment of formal rights. Equally, the everyday, lived, experiences and practices of citizenship contribute to, and help shape, the perceptions and understandings of anti-terrorism policy from within the citizenry     

Improved gas chromatography-negative ion chemical ionization tandem mass spectrometric method for determination of 11-nor-Δ9-tetrahydrocannabinol-9-carboxylic acid in hair using mechanical pulverization and bead-assisted liquid-liquid extraction

A gas chromatography-negative ion chemical ionization tandem mass spectrometric (GC-NCI-MS/MS) method was developed and validated for the determination of 11-nor-Δ(9)-tetrahydrocannabinol-9-carboxylic acid (THC-COOH) in human hair. After decontamination, hair samples were weighed (25mg), mechanically pulverized with a bead mill, and incubated in 0.7 mL of 1.0M sodium hydroxide at 95 °C for 30 min. Bead-assisted liquid-liquid extraction was performed with n-hexane:ethyl acetate (9:1, v/v), a method developed in our laboratory. The extract was evaporated to dryness, derivatized with pentafluoropropanol and pentafluoropropionic anhydride, and analyzed by GC-MS/MS in the negative ion chemical ionization mode using methane as the reagent gas. The linear ranges were 0.05-10.0 pg/mg for THC-COOH with the coefficient of determination (r(2) = 0.9976). The intra-day and inter-day precisions were within 1.7 and 13.8%, respectively. The intra-day and inter-day accuracies were -4.8 to 10.0% and -3.9 to 3.8%, respectively. The limit of detection and quantification were 0.015 and 0.05 pg/mg, respectively. The recoveries were in the range of 79.4-87.1%. The results indicate that the proposed method is simple, rapid, accurate, and precise for determination of THC-COOH in hair. The method identified THC-COOH in hair specimens from suspected marijuana abusers.     

Analysis of hair after contamination with blood containing 6-acetylmorphine and blood containing morphine

The study was carried out to investigate external contamination of hair by blood in heroin-related post-mortem cases. Solutions were prepared containing 0.05, 0.1, 0.2, 0.5 and 3.0μg/mL of 6-monoacetylmorphine (6-AM) only or morphine only in human blood. Samples of approximately 3.2g of drug-free hair were contaminated by soaking in the blood solutions for 5min. They were then removed and left at room temperature. Approximately 0.5g of hair was collected from each of the blood soaked hair samples at 6h, 1, 2, 4 and 7 days after contamination. As each hair sample was collected it was shampoo-washed to prevent further drug absorption. Hair samples were analysed in triplicate using a fully validated method described previously. 6-AM broke down to morphine in all samples. In hair contaminated with blood containing 0.05, 0.1 and 0.2μg/mL 6-AM or morphine drug was either not detected or was detected below the limit of quantitation (0.2ng/mg hair) at all contamination times. In hair contaminated with blood spiked with 0.5μg/mL morphine, the concentration in hair ranged from 0.54 to 0.91ng/mg and in hair contaminated with blood spiked with 3.0μg/mL, from 3.25 to 5.77ng/mg. The concentrations of 6-AM ranged from 0.65 to 1.11ng/mg and morphine from 0.34 to 0.80ng/mg in hair contaminated with 0.5μg/mL 6-AM in blood. 6-AM ranged from 2.12 to 3.67ng/mg and morphine from 0.84 to 2.05ng/mg in hair contaminated with 3μg/mL 6-AM in blood. For 6-AM and morphine ANOVA statistical evaluation showed no significant difference among the concentrations over time.     

Safety,Regulation and Tort: Fault in Context

The relationship between tort and regulation is dense and complicated. This paper examines diverse approaches to one small element of this relationship: the relationship between regulatory norms and the standard of care in personal injury cases. The lack of clear rules governing that interaction is not surprising: we would never expect the courts to give up the authority (or abdicate the responsibility) to generate private law norms; on the other hand, nor would we expect them to ignore the potential authority and legitimacy of external norms. The strength of external standards is best identified by close scrutiny of the regulation itself. The varying authority of external norms in a private law forum requires engagement with the process by which the external norms were reached. Who and what determined the ‘ought’ of regulation will provide greater insight into the ways in which it should inform the ‘ought’ of tort.     

HUNTER‐GATHERER COLLABORATIVE PRACTICE

This article describes the development of a practice group based on a hunter‐gatherer model, with the mission of providing high quality collaborative divorce services, with an emphasis on protecting children and divorcing partners, and expanding access to middle‐ and lower‐income families. The practice group professional disciplines include law, mental health divorce coaching, co‐parent coaching, financial analysis, and case administration. These professionals have collectively associated their individual practices to address challenges facing their collaborative practices. With common purpose, the practice group builds skills, generates client base, nurtures trust, and lays a common knowledge base. Collaborative divorce teams formed from its members serve divorcing families with efficient, cost‐conscious, interest‐based negotiation processes that protect children and help parties productively move on with their lives.     

Accidental death from hydromorphone ingestion

Abstract: A 15‐year‐old male orally consumed an unknown but fatal amount of sustained release hydromorphone. He was naïve to opioid use. No other drugs or alcohol were involved. The cause of death was acute aspiration‐related bronchopneumonia, secondary to hydromorphone ingestion; the manner of death was accidental. Hydromorphone and hydromorphone‐3‐glucuronide were quantified in postmortem fluids by tandem liquid chromatography–mass spectrometry. The hydromorphone concentrations in the peripheral blood, urine, and vitreous humor were 57, 4460, and 31 ng/mL, respectively. The hydromorphone‐3‐glucuronide concentrations in the corresponding three fluids were 459, 36,400, and 40 ng/mL. Hydromorphone‐3‐glucuronide accumulation probably did not contribute significantly to the opiate toxicity. The proposed minimum lethal hydromorphone blood concentration in the nontolerant user is in the vicinity of 60 ng/mL.     

Validity of Demirjian's and modified Demirjian's methods in age estimation for Korean juveniles and adolescents

In estimating age of juveniles and adolescents, the teeth are employed primarily because of its low variability and less affection by endocrine and nutritional status in development. Demirjian established criteria for evaluating maturity of teeth and his method has been used throughout the world. However, several studies showed the inappropriateness of Demirjian's method on populations other than the one it is based on. Consequently some researchers modified Demirjian's method using data of several different populations. Demirjian himself also published a revised method to overcome other shortcomings of his original method. The aim of this study was to test the validity of Demirjian's and the modified methods (Demirjian's revised, Willems', Chaillet's and new Korean methods) for Korean juveniles and adolescents. 1483 digital orthopantomograms which consist of 754 males and 729 females in the age range of 3-16 years were collected. New age estimation method based on Korean population data was calculated. Dental age was estimated according to each method and the validity was evaluated using the differences between chronological and dental age. The inter- and intra-observer reliability was evaluated to be excellent. Statistically significant difference was observed between chronological and dental age in all the methods for both sexes except new Korean method for both sexes and Demirjian's revised method for males. However, when analyzing absolute and squared value of difference, Willems' method was found to be most accurate followed by new Korean method with slight difference for Korean population for both sexes. In conclusion, both Willems' method and new Korean method conducted by present study were proven to be suitable for Korean population.     

Establishment of the measurement uncertainty of 11-nor-D9-tetrahydrocannabinol-9-carboxylic acid in hair

The quantitative analysis of 11-nor-D(9)-tetrahydrocannabinol-9-carboxylic acid (THCCOOH) in hair requires a sensitive method to detect a low-pg level. Before applying the method to real hair samples, the method was validated; in this study, we examined the uncertainty obtained from around the cut-off level of THCCOOH in hair. We calculated the measurement uncertainty (MU) of THCCOOH in hair as follows: specification of the measurand, identification of parameters using "cause and effect" diagrams, quantification of the uncertainty contributions using three factors, the uncertainty of weighing the hair sample, the uncertainty from calibrators and the calibration curve, and the uncertainty of the method precision. Finally, we calculated the degrees of freedom and the expanded uncertainty (EU). The concentration of THCCOOH in the hair sample with its EU was (0.60 ± 0.1) × 10(-4)ng/mg. The relative uncertainty percent for the measurand 0.60 × 10(-4)ng was 9.13%. In this study, we also selected different concentrations of THCCOOH in real hair samples and then calculated the EU, the relative standard uncertainty (RSU) of the concentration of THCCOOH in the test sample [u(r)(c0)], the relative uncertainty percent, and the effective degree of freedom (v(eff)). When the concentrations of THCCOOH approached the cut-off level, u(r)(c0) and the relative uncertainty percent increased but absolute EU and v(eff) decreased.     

A study on the concentrations of 11-nor-Δ(9)-tetrahydrocannabinol-9-carboxylic acid (THCCOOH) in hair root and whole hair

In this study, we investigated the patterns of cannabis users (n=412) according to their sex, age, and the results of urinalysis and hair analysis, and classified the concentrations of THCCOOH in hair into three categories to examine the levels of cannabis use. We also compared the concentrations of THCCOOH in hair root, hair without the hair root and whole hair and examined the relationship among them according to the results of urinalysis. The hair samples were washed, digested with 1ml of 1M NaOH at 85°C for 30min and extracted with 2ml of n-hexane:ethyl acetate (9:1) two times after adding 1ml of 0.1N sodium acetate buffer (pH 4.5) and 200μl of acetic acid. The final mixture was derivatized with 50μl of PFPA and 25μl of PFPOH for 30min at 70°C. The solution was evaporated, and the residue was reconstituted in 40μl of ethyl acetate and transferred to an autosampler vial. One microlitre was injected into the GC/MS/MS-NCI system. The concentrations of THCCOOH ranged from 0.06 to 33.44pg/mg (mean 2.96; median 1.32) in hair from cannabis users who had positive urine results and ranged from 0.05 to 7.24pg/mg (mean 1.35; median 0.37) in hair from cannabis users who had negative urine results. The average concentration of THCCOOH in hair from cannabis users who had positive urine results was higher than that from cannabis users who had negative urine results. Male cannabis users in their forties were predominant. We classified the concentrations of THCCOOH in hair into three groups (low, medium and high), and could use the grouping of THCCOOH in hair as a guide for determining the level of use. The low, medium and high concentration ranges for THCCOOH in hair were 0.05-0.24, 0.25-2.60 and 2.63-33.44pg/mg, respectively. We also investigated 28 hair samples with the root. The highest concentrations of THCCOOH were seen in the hair root from 18 out of the 28 hair samples. The average concentrations of THCCOOH in hair root, hair without hair root and whole hair from cannabis users who had positive urine results were higher than those who had negative urine results.
