Public Inquiries on Counterterrorism: An Independent Appraisal of New Zealand's Royal Commission of Inquiry into the Christchurch Terrorist Attack

Draft-in-progress; please do not distribute further or citeEven though elected leaders of liberal democracies respond to major terrorist attacks by commissioning public inquiries, scholars have not yet fully explored these inquiries as a practice of the War on Terror. By undertaking an independent appraisal of the Royal Commission of Inquiry into the Terrorist Attack on Christchurch Mosques on 15 March 2019 we seek to introduce empirical evidence of an important case of investigatory oversight to the more critical terrorism studies literature. Specifically, we examine how the Royal Commissioners interpreted their Terms of Reference, explore the ways in which they engaged with New Zealand’s security agencies as well as with various individuals, groups and communities beyond the public sector, and assess the quality of their recommendations. We argue that the Commissioners positioned themselves publicly as undertaking a remedial intervention in New Zealand’s counterterrorism effort, but their inquiry was, in fact, designed to reassure the public that the current security dispensation is largely fit for purpose and does not need major reform. The inquiry did little more than enable two carefully chosen Commissioners, imbued with a veneer of professional detachment but lacking in subject-matter expertise, to call for a strengthening of state security institutions, entrenching the hierarchies that already prevail within the national security system while shielding parliamentarians from accusations of disinterest, negligence or acts of omission. Consequently, New Zealand is no better off when it comes to its ability to understand the nature and scale of the threat posed by terrorism or to respond to an array of routine, as well as novel and surprise, security challenges

A systematic evaluation of current control devices used by people with intellectual disabilities in non-immersive virtual environments

Virtual environments have a role to play in facilitating the acquisition of living skills in people with intellectual disabilities, improving their cognitive skills and providing them with entertainment. However, the currently recommended devices to allow navigation in and interaction with the environments are difficult to use. Using a methodology established in an earlier study, the study aims to systematically document the performance of users with the currently recommended devices in order to (i) inform the design of a usable control device or devices and (ii) act as a baseline against which they can be evaluated. 40 people with severe intellectual disabilities aged 21–67 years used four environments with an equal number of sessions with the different devices being evaluated. Results indicate that when forward movement is provided by the software using the mouse for both navigation and interaction allows better performance both initially and after exposure than using the fire button on the joystick. When the user had to initiate forward movement with the navigation device, the joystick allowed better performance than the arrows on the keyboard. Preventing slippage of the joystick base would make its use much easier and it is suggested that separate devices are retained for navigation and interaction

An evaluation of the use of a computer game in improving the choice reaction time of adults with intellectual disabilities

People with intellectual disabilities have difficulty making decisions and this may hinder their independence and inclusion in society. Interactive computer software may give them the opportunity to practice the underlying components of this skill. This study aimed to discover if repeated sessions playing a computer game involving aspects of decision making, such as collecting relevant information and controlling impulsivity, would improve performance in two non-computer based tests of decision making. 12 adults with intellectual disabilities were randomly assigned to either an intervention group or control group. They were all exposed to 10 twice weekly sessions, playing either the intervention game or the control game, which involved simple reaction time only. After repeated sessions, the intervention group showed a significant improvement in game score, with researcher assistance significantly decreasing. At follow up, the intervention group showed a significant decrease from baseline in the number of guesses made before guessing correctly on both of the decision making tests. The decrease observed in the control group failed to reach significance

Postnatal corticosteroid use for prevention or treatment of Bronchopulmonary Dysplasia in England and Wales 2012-2019: a retrospective population cohort study

Objective: Describe the population of babies who do and do not receive postnatal corticosteroids for prevention or treatment of bronchopulmonary dysplasia (BPD). Design: Retrospective cohort study using data held in the National Neonatal Research Database. Setting: National Health Service neonatal units in England and Wales. Patients: Babies born less than 32 weeks gestation and admitted to neonatal units from 1 January 2012 to 31 December 2019. Main outcomes: Proportion of babies given postnatal corticosteroid; type of corticosteroid; age at initiation and duration, trends over time. Secondary outcomes: Survival to discharge, treatment for retinopathy of prematurity, BPD, brain injury, severe necrotising enterocolitis, gastrointestinal perforation. Results: 8% (4713/62019) of babies born <32 weeks and 26% (3525/13527) born <27 weeks received postnatal corticosteroids for BPD. Dexamethasone was predominantly used 5.3% (3309/62019), followed by late hydrocortisone 1.5%, inhaled budesonide 1.5%. prednisolone 0.8%, early hydrocortisone 0.3% and methylprednisolone 0.05%. Dexamethasone use increased over time (2012: 4.5 vs 2019: 5.8%, p=0.04). Median postnatal age of initiation of corticosteroid course was around 3 weeks for late hydrocortisone, 4 weeks for dexamethasone, 6 weeks for inhaled budesonide, 12 weeks for prednisolone and 16 weeks for methylprednisolone. Babies who received postnatal corticosteroids were born more prematurely, had a higher incidence of comorbidities and a longer length of stay. Conclusions: In England and Wales, around 1 in 12 babies born less than 32 weeks and 1 in 4 born less than 27 weeks receive postnatal corticosteroids to prevent or treat BPD. Given the lack of convincing evidence of efficacy, challenges of recruiting to and length of time taken to conduct randomised controlled trial, our data highlight the need to monitor long-term outcomes in children who received neonatal postnatal corticosteroids

Outcomes in relation to early parenteral nutrition use in preterm neonates born between 30 and 33 weeks gestation: a propensity score matched observational study

Objective To evaluate whether in preterm neonates parenteral nutrition use in the first seven postnatal days, compared with no parenteral nutrition use, is associated with differences in survival and other important morbidities. Randomised trials in critically ill older children show that harms, such as nosocomial infection, outweigh benefits of early parenteral nutrition administration; there is a paucity of similar data in neonates. Design Retrospective cohort study using propensity matching including 35 maternal, infant and organisational factors to minimise bias and confounding. Setting National, population-level clinical data obtained for all National Health Service neonatal units in England and Wales. Patients Preterm neonates born between 30+0 and 32+6 weeks+days . Interventions The exposure was parenteral nutrition administered in the first seven days of postnatal life; the comparator was no parenteral nutrition. Main outcome measures The primary outcome was survival to discharge from neonatal care. Secondary outcomes comprised the neonatal core outcome set. Results 16,292 neonates were compared in propensity score matched analyses. Compared with matched neonates not given parenteral nutrition in the first postnatal week, neonates who received parenteral nutrition had higher survival at discharge (absolute rate increase 0.91%; 95% CI 0.53% to 1.30%), but higher rates of necrotising enterocolitis (absolute rate increase 4.6%), bronchopulmonary dysplasia (absolute rate increase 3.9%), late-onset sepsis (absolute rate increase 1.5%) and need for surgical procedures (absolute rate increase 0.92%). Conclusions In neonates born between 30+0 and 32+6 weeks gestation, those given parenteral nutrition in the first postnatal week had a higher rate of survival but higher rates of important neonatal morbidities. Clinician equipoise in this area should be resolved by prospective, randomised trials

Characterizing precursors to stellar clusters with Herschel

Context. Despite their profound effect on the universe, the formation of massive stars and stellar clusters remains elusive. Recent advances in observing facilities and computing power have brought us closer to understanding this formation process. In the past decade, compelling evidence has emerged that suggests infrared dark clouds (IRDCs) may be precursors to stellar clusters. However, the usual method for identifying IRDCs is biased by the requirement that they are seen in absorption against background mid-IR emission, whereas dust continuum observations allow cold, dense pre-stellar-clusters to be identified anywhere. Aims: We aim to understand what dust temperatures and column densities characterize and distinguish IRDCs, to explore the population of dust continuum sources that are not IRDCs, and to roughly characterize the level of star formation activity in these dust continuum sources. Methods: We use Hi-GAL 70 to 500 $m data to identify dust continuum sources in the ell = 30deg and ell = 59deg Hi-GAL science demonstration phase (SDP) fields, to characterize and subtract the Galactic cirrus emission, and perform pixel-by-pixel modified blackbody fits on cirrus-subtracted Hi-GAL sources. We utilize archival Spitzer data to indicate the level of star-forming activity in each pixel, from mid-IR-dark to mid-IR-bright. Results: We present temperature and column density maps in the Hi-GAL ell = 30deg and ell = 59deg SDP fields, as well as a robust algorithm for cirrus subtraction and source identification using Hi-GAL data. We report on the fraction of Hi-GAL source pixels which are mid-IR-dark, mid-IR-neutral, or mid-IR-bright in both fields. We find significant trends in column density and temperature between mid-IR-dark and mid-IR-bright pixels; mid-IR-dark pixels are about 10 K colder and have a factor of 2 higher column density on average than mid-IR-bright pixels. We find that Hi-GAL dust continuum sources span a range of evolutionary states from pre- to star-forming, and that warmer sources are associated with more star formation tracers. Additionally, there is a trend of increasing temperature with tracer type from mid-IR-dark at the coldest, to outflow/maser sources in the middle, and finally to 8 and 24$m bright sources at the warmest. Finally, we identify five candidate IRDC-like sources on the far-side of the Galaxy. These are cold (20 K), high column density (N(H$_2$) gt 10$^22$ cm$^-2$) clouds identified with Hi-GAL which, despite bright surrounding mid-IR emission, show little to no absorption at 8 $m. These are the first inner Galaxy far-side candidate IRDCs of which the authors are aware.

Incorporating parent, former patient, and clinician perspectives in the design of a national UK double-cluster, randomised controlled trial addressing uncertainties in preterm nutrition

Background: Comparative effectiveness randomised controlled trials are powerful tools to resolve uncertainties in existing treatments and care processes. We sought parent and patient perspectives on the design of a planned national, double-cluster randomised controlled trial (COLLABORATE) to resolve two longstanding uncertainties in preterm nutrition. Methods: We used qualitative focus groups and interviews with parents, former patients and clinicians. We followed the Consolidated Criteria for Reporting Qualitative Research checklist and conducted framework analysis, a specific methodology within thematic analysis. Results: We identified support for the trial’s methodology and vision, and elicited themes illustrating parents’ emotional needs in relation to clinical research. These were: relieving the pressure on mothers to breastfeed; opt-out consent as reducing parent stress; the desire for research to be a partnership between clinicians, parents and researchers; the value of presenting trial information in a collaborative tone; and in a format that allows assimilation by parents at their own pace. We identified anxiety and cognitive dissonance among some clinicians in which they recognised the uncertainties that justify the trial but felt unable to participate because of their strongly held views. Conclusions: The early involvement of parents and former patients identified the centrality of parents’ emotional needs in the design of comparative effectiveness research. These insights have been incorporated into trial enrolment processes and information provided to participants. Specific outputs were a two-sided leaflet providing very brief as well as more detailed information, and use of language that parents perceive as inclusive and participatory. Further work is warranted to support clinicians to address personal biases that inhibit trial participation

"Our people has got to come to terms with that": changing perceptions of the digital rectal examination as a barrier to prostate cancer diagnosis in African-Caribbean men

Objective: African‐Caribbean men in the United Kingdom in comparison with other ethnicities have the highest incidence rate of prostate cancer. Psychosocial aspects related to screening and presentation impact on men's behavior, with previous studies indicating a range of barriers. This study explores one such barrier, the digital rectal examination (DRE), due to its prominence within UK African‐Caribbean men's accounts. Methods: African‐Caribbean men with prostate cancer (n = 10) and without cancer (n = 10) were interviewed about their perceptions of DRE. A synthetic discursive approach was employed to analyze the data. Results: Findings illustrate that an interpretative repertoire of homophobia in relation to the DRE is constructed as having an impact upon African‐Caribbean men's uptake of prostate cancer screening. However, the discursive focus on footing and accountability highlight deviations from this repertoire that are built up as pragmatic and orient to changing perceptions within the community. Conclusions: Health promotion interventions need to address the fear of homophobia and are best designed in collaboration with the community
