Explaining counterterrorism in the UK: Normal politics, securitized politics or performativity of the neoliberal state?
This paper seeks to explore the politics of counter terrorism in the UK. It argues that for a number of reasons, counter terrorism policy has been separated off from other policy areas and seen as securitised, exceptional or just different. The paper argues that such a separation from ânormalâ politics is problematic, both conceptually and empirically. It argues that much can be gained by considering counter terrorism policy through the lenses, concepts and debates which feature in other areas of British politics. The paper then examines two such lenses/debates â depoliticisation and neoliberalism. An argument is developed that counter terrorism policy is not, in the main, depoliticised, but rather overt, politicised and visible. This prominence, it is argued, is due to the ways in which neoliberalism has reduced many of the traditional roles of the state. Drawing on the work of Wacquant and Hall, the paper argues that in the absence of such traditional roles, counter terrorism offers the state an opportunity to perform its own âstatenessâ, to visibly display its sovereign power in a context of ever more (self-imposed) diminished powers
Coding potential of the products of alternative splicing in human
Background: Analysis of the human genome has revealed that as much as an order of magnitude more of the genomic sequence is transcribed than accounted for by the predicted and characterized genes. A number of these transcripts are alternatively spliced forms of known protein coding genes; however, it is becoming clear that many of them do not necessarily correspond to a functional protein. Results: In this study we analyze alternative splicing isoforms of human gene products that are unambiguously identified by mass spectrometry and compare their properties with those of isoforms of the same genes for which no peptide was found in publicly available mass spectrometry datasets. We analyze them in detail for the presence of uninterrupted functional domains, active sites as well as the plausibility of their predicted structure. We report how well each of these strategies and their combination can correctly identify translated isoforms and derive a lower limit for their specificity, that is, their ability to correctly identify non-translated products. Conclusions: The most effective strategy for correctly identifying translated products relies on the conservation of active sites, but it can only be applied to a small fraction of isoforms, while a reasonably high coverage, sensitivity and specificity can be achieved by analyzing the presence of non-truncated functional domains. Combining the latter with an assessment of the plausibility of the modeled structure of the isoform increases both coverage and specificity with a moderate cost in terms of sensitivity
Synthesis of Janus compounds for the recognition of G-U mismatched nucleobase pairs
The design and synthesis of two Janus-type heterocycles with the capacity to simultaneously recognize guanine and uracyl in G-U mismatched pairs through complementary hydrogen bond pairing is described. Both compounds were conveniently functionalized with a carboxylic function and efficiently attached to a tripeptide sequence by using solid-phase methodologies. Ligands based on the derivatization of such Janus compounds with a small aminoglycoside, neamine, and its guanidinylated analogue have been synthesized, and their interaction with Tau RNA has been investigated by using several biophysical techniques, including UV-monitored melting curves, fluorescence titration experiments, and 1H NMR. The overall results indicated that Janus-neamine/guanidinoneamine showed some preference for the +3 mutated RNA sequence associated with the development of some tauopathies, although preliminary NMR studies have not confirmed binding to G-U pairs. Moreover, a good correlation has been found between the RNA binding affinity of such Janus-containing ligands and their ability to stabilize this secondary structure upon complexation
Brief Report: Testing the Psychometric Properties of the Spence Childrenâs Anxiety Scale (SCAS) and the Screen for Child Anxiety Related Emotional Disorders (SCARED) in Autism Spectrum Disorder
Anxiety is a prevalent and impairing co-morbidity among individuals with autism spectrum disorder (ASD), yet assessment measures, including screening tools, are seldom validated with autism samples. We explored the psychometric properties of the child and parent reports of the Spence Childrenâs Anxiety Scale (SCAS) and the Screen for Anxiety Related Disorder-71 (SCARED-71) with 49 males with ASD (10â16 years, 63% co-occurring anxiety). Both measures had excellent internal consistency and fair-good parentâchild agreement. The SCAS has a higher proportion of items evaluating observable behaviors. Predictive power of the measures did not differ. Higher cut-points in the parent reports (SCARED only) and lower cut-points in the child reports may enhance prediction in this sample. Choice of measure and cut-points should be considered alongside intended purpose
Islamophobia in the National Health Service: an ethnography of institutional racism in PREVENT's counterâradicalisation policy
In 2015, the UK government made its counterâradicalisation policy a statutory duty for all National Health Service (NHS) staff. Staff are now tasked to identify and report individuals they suspect may be vulnerable to radicalisation. Prevent training employs a combination of psychological and ideological frames to convey the meaning of radicalisation to healthcare staff, but studies have shown that the threat of terrorism is racialised as well. The guiding question of our ethnography is: how is counterâradicalisation training understood and practiced by healthcare professionals? A frame analysis draws upon 2 years of ethnographic fieldwork, which includes participant observation in Prevent training and NHS staff interviews. This article demonstrates how Prevent engages in performative colourâblindness â the active recognition and dismissal of the race frame which associates racialised Muslims with the threat of terrorism. It concludes with a discussion of institutional racism in the NHS â how racialised policies like Prevent impact the minutia of clinical interactions; how the pretence of a âpostâracialâ society obscures institutional racism; how psychologisation is integral to the performance of colourâblindness; and why it is difficult to address the racism associated with colourblind policies which purport to address the threat of the FarâRight
Kondo flow invariants, twisted K-theory and Ramond-Ramond charges
We take a worldsheet point of view on the relation between Ramond-Ramond
charges, invariants of boundary renormalization group flows and K-theory. In
compact super Wess-Zumino-Witten models, we show how to associate invariants of
the generalized Kondo renormalization group flows to a given supersymmetric
boundary state. The procedure involved is reminiscent of the way one can probe
the Ramond-Ramond charge carried by a D-brane in conformal field theory, and
the set of these invariants is isomorphic to the twisted K-theory of the Lie
group. We construct various supersymmetric boundary states, and we compute the
charges of the corresponding D-branes, disproving two conjectures on this
subject. We find a complete agreement between our algebraic charges and the
geometry of the D-branes.Comment: 58 pages. V4 : Problem with the bibliography correcte
New Non-Intravenous Routes for Benzodiazepines in Epilepsy: A Clinician Perspective.
Benzodiazepines represent the first-line treatment for the acute management of epileptic seizures and status epilepticus. The emergency use of benzodiazepines must be timely, and because most seizures occur outside of the hospital environment, there is a significant need for delivery methods that are easy for nonclinical caregivers to use and administer quickly and safely. In addition, the ideal route of administration should be reliable in terms of absorption. Rectal diazepam is the only licensed formulation in the USA, whereas rectal diazepam and buccal midazolam are currently licensed in the EU. However, the sometimes unpredictable absorption with rectal and buccal administration means they are not ideal routes. Several alternative routes are currently being explored. This is a narrative review of data about delivery methods for benzodiazepines alternative to the intravenous and oral routes for the acute treatment of seizures. Unconventional delivery options such as direct delivery to the central nervous system or inhalers are reported. Data show that intranasal diazepam or midazolam and the intramuscular auto-injector for midazolam are as effective as rectal or intravenous diazepam. Head-to-head comparisons with buccal midazolam are urgently needed. In addition, the majority of trials focused on children and adolescents, and further trials in adults are warranted
Excretion of catecholamines in rats, mice and chicken
Stress assessment favours methods, which do not interfere with an animalâs endocrine status. To develop such non-invasive methods, detailed knowledge about the excretion of hormone metabolites in the faeces and urine is necessary. Our study was therefore designed to generate basic information about catecholamine excretion in rats, mice and chickens. After administration of 3H-epinephrine or 3H-norepinephrine to male and female rats, mice and chickens, all voided excreta were collected for 4Â weeks, 3Â weeks or for 10Â days, respectively. Peak concentrations of radioactivity appeared in one of the first urinary samples of mice and rats and in the first droppings in chickens 0.2â7.2Â h after injection. In rats, between 77.3 and 95.6% of the recovered catecholamine metabolites were found in the urine, while in mice, a mean of 76.3% were excreted in the urine. Peak concentrations in the faeces were found 7.4Â h post injection in mice, and after about 16.4Â h in rats (means). Our study provides valuable data about the route and the profile of catecholamine excretion in three frequently used species of laboratory animals. This represents the first step in the development of a reliable, non-invasive quantification of epinephrine and norepinephrine to monitor sympatho-adrenomedullary activity, although promising results for the development of a non-invasive method were found only for the chicken
Registered replication report on Fischer, Castel, Dodd, and Pratt (2003)
The attentional spatial-numerical association of response codes (Att-SNARC) effect (Fischer, Castel, Dodd, & Pratt, 2003)âthe finding that participants are quicker to detect left-side targets when the targets are preceded by small numbers and quicker to detect right-side targets when they are preceded by large numbersâhas been used as evidence for embodied number representations and to support strong claims about the link between number and space (e.g., a mental number line). We attempted to replicate Experiment 2 of Fischer et al. by collecting data from 1,105 participants at 17 labs. Across all 1,105 participants and four interstimulus-interval conditions, the proportion of times the effect we observed was positive (i.e., directionally consistent with the original effect) was .50. Further, the effects we observed both within and across labs were minuscule and incompatible with those observed by Fischer et al. Given this, we conclude that we failed to replicate the effect reported by Fischer et al. In addition, our analysis of several participant-level moderators (finger-counting habits, reading and writing direction, handedness, and mathematics fluency and mathematics anxiety) revealed no substantial moderating effects. Our results indicate that the Att-SNARC effect cannot be used as evidence to support strong claims about the link between number and space
Identification of PRRT2 as the causative gene of paroxysmal kinesigenic dyskinesias
Paroxysmal kinesigenic dyskinesias is a paroxysmal movement disorder characterized by recurrent, brief attacks of abnormal involuntary movements induced by sudden voluntary movements. Although several loci, including the pericentromeric region of chromosome 16, have been linked to paroxysmal kinesigenic dyskinesias, the causative gene has not yet been identified. Here, we identified proline-rich transmembrane protein 2 (PRRT2) as a causative gene of paroxysmal kinesigenic dyskinesias by using a combination of exome sequencing and linkage analysis. Genetic linkage mapping with 11 markers that encompassed the pericentromeric of chromosome 16 was performed in 27 members of two families with autosomal dominant paroxysmal kinesigenic dyskinesias. Then, the whole-exome sequencing was performed in three patients from these two families. By combining the defined linkage region (16p12.1âq12.1) and the results of exome sequencing, we identified an insertion mutation c.649_650InsC (p.P217fsX7) in one family and a nonsense mutation c.487C>T (p.Q163X) in another family. To confirm our findings, we sequenced the exons and flanking introns of PRRT2 in another three families with paroxysmal kinesigenic dyskinesias. The c.649_650InsC (p.P217fsX7) mutation was identified in two of these families, whereas a missense mutation, c.796C>T (R266W), was identified in another family with paroxysmal kinesigenic dyskinesias. All of these mutations completely co-segregated with the phenotype in each family. None of these mutations was identified in 500 normal unaffected individuals of matched geographical ancestry. Thus, we have identified PRRT2 as the first causative gene of paroxysmal kinesigenic dyskinesias, warranting further investigations to understand the pathogenesis of this disorder
