Get fact: were there really 50,000 boat arrivals a year under Labor?

Tony Abbott has claimed that before he “stopped the boats”, they were coming in at a rate of 50,000 a year. Is that true? David Tittensor, a research fellow to the UNESCO Chair, with Deakin’s Centre for Citizenship and Globalisation, checks the claim

Islam\u27s Modern Day Ibn Battutas: Gülen teachers journeying towards the divine

There is a longstanding debate on whether Muslims can be modern. Some argue that they can only be so if they forsake their traditions and embrace rationalism. In this article I argue that the Gülen Movement, a transnational Turkish Muslim educational activist network has found a middle ground by blending religious traditions with modern day realities. Drawing on interviews from the movement\u27s teachers and graduates of its schools, from Turkey, Central Asia, Afghanistan and Pakistan, I explore, through the prism of al-riḥla fī ṭalab al-ʿilm (travel in search of knowledge), their maintenance of the longstanding Islamic ritual of travel as a means of excelling both professionally and religiously. In turn, I demonstrate how the movement, on a number of levels, effectively reconciles the spiritual and the everyday through updating Islamic practices to better integrate themselves and other Muslims into a globalised world

A global map to aid the identification and screening of critical habitat for marine industries

Marine industries face a number of risks that necessitate careful analysis prior to making decisions on the siting of operations and facilities. An important emerging regulatory framework on environmental sustainability for business operations is the International Finance Corporation’s Performance Standard 6 (IFC PS6). Within PS6, identification of biodiversity significance is articulated through the concept of “Critical Habitat”, a definition developed by the IFC and detailed through criteria aligned with those that support internationally accepted biodiversity designations. No publicly available tools have been developed in either the marine or terrestrial realm to assess the likelihood of sites or operations being located within PS6-defined Critical Habitat. This paper presents a starting point towards filling this gap in the form of a preliminary global map that classifies more than 13 million km2 of marine and coastal areas of importance for biodiversity (protected areas, Key Biodiversity Areas [KBA], sea turtle nesting sites, cold- and warm-water corals, seamounts, seagrass beds, mangroves, saltmarshes, hydrothermal vents and cold seeps) based on their overlap with Critical Habitat criteria, as defined by IFC. In total, 5798×103 km2 (1.6%) of the analysis area (global ocean plus coastal land strip) were classed as Likely Critical Habitat, and 7526×103 km2 (2.1%) as Potential Critical Habitat; the remainder (96.3%) were Unclassified. The latter was primarily due to the paucity of biodiversity data in marine areas beyond national jurisdiction and/or in deep waters, and the comparatively fewer protected areas and KBAs in these regions. Globally, protected areas constituted 65.9% of the combined Likely and Potential Critical Habitat extent, and KBAs 29.3%, not accounting for the overlap between these two features. Relative Critical Habitat extent in Exclusive Economic Zones varied dramatically between countries. This work is likely to be of particular use for industries operating in the marine and coastal realms as an early screening aid prior to in situ Critical Habitat assessment; to financial institutions making investment decisions; and to those wishing to implement good practice policies relevant to biodiversity management. Supplementary material (available online) includes other global datasets considered, documentation and justification of biodiversity feature classification, detail of IFC PS6 criteria/scenarios, and coverage calculations

The rodent uterotrophic assay: Critical protocol features, studies with nonyl phenols, and comparison with a yeast estrogenicity assay

The major protocol features of the immature rat uterotrophic assay have been evaluated using a range of reference chemicals. The protocol variables considered include the selection of the test species and route of chemical administration, the age of the test animals, the maintenance diet used, and the specificity of the assay for estrogens. It is concluded that three daily oral administrations of test chemicals to 21- to 22-day-old rats, followed by determination of absolute uterus weights on the fourth day, provide a sensitive and toxicologically relevant in vivo estrogenicity assay. Rats are favored over mice for reasons of toxicological practice, but the choice of test species is probably not a critical protocol variable, as evidenced by the similar sensitivity of rats and mice to the uterotrophic activity of methoxychlor. Vaginal opening is shown to be a useful, but nondefinitive, adjunct to the uterotrophic assay. The ability of test chemicals to reduce or abolish the uterotrophic response of estradiol is suggested to provide a useful extension of the uterotrophic assay for the purpose of detecting antiestrogens. The results of a series of studies on the environmental estrogen nonyl phenol (NP), and its linear isomer n -nonyl phenol, confirm that branching of the aliphatic side chain is important for activity. 17beta-Desoxyestradiol is shown to be of similar activity to estradiol in the uterotrophic assay and is suggested to represent the "parent" estrogen of NP. Benzoylation of NP and 17-desoxyestradiol did not affect their uterotrophic activity, in contrast to the enhancing effect of benzoylation on estradiol. Selected chemicals shown to be active in the immature rat uterotrophic assay were also evaluated in an in vitro yeast human estrogen receptor transactivation assay. Most of the chemicals gave similar qualitative responses to those seen in the uterotrophic assay, and the detection of the estrogen methoxychlor by the yeast assay evidenced a degree of intrinsic metabolic competence. However, the assay had a reduced ability (compared to rodents) to hydrolyze the benzoate ester of estradiol, and the estrogenic benzoate derivative of NP was not active in the yeast assay. These last results indicate that current metabolic deficiencies of in vitro estrogenicity assays will limit the value of negative data for the immediate future. The results described illustrate the intrinsic complexity of evaluating chemicals for estrogenic activities and confirm the need for rigorous attention to experimental design and criteria for assessing estrogenic activity

National compliance with UK wide guidelines for usage of valproate in women of childbearing potential.

Valproate (VPA) is an effective treatment for epilepsy and also used in bipolar disorder. However, VPA is associated with a significant risk of birth defects and developmental disorders if used during pregnancy. This has led to the introduction of measures to reduce the use of valproate in women of childbearing potential such as the 'Prevent' pregnancy prevention program (PPP) and the completion of an annual risk acknowledgement form (ARAF). The aim of the current audit was to assess compliance with the guidance. An audit tool was made available to neurologists registered with the Association of British Neurologists (ABN) and to epilepsy nurse specialists via the Epilepsy Nurses Association (ESNA) in the UK. Data were collected between November 2020 and March 2021. The main indication for valproate was generalised epilepsy (55.8%), followed by focal (22.5%). For most, there was documentation that the woman had been informed about the risks associated with taking valproate during pregnancy (93.1%) and the need to be on highly effective contraception or that this was not deemed appropriate (92.2%). A signed ARAF was available in the notes for 81.2% although only 66% were <12 months old. Although information had been made available for most women, there were still individuals where this was not documented. Further work is needed to facilitate identification of women taking valproate and implementation of a digital ARAF. For clinicians, the audit highlights a need to carefully counsel women about the teratogenic risks of continuing to take valproate versus the risk of deteriorating seizure control if the drug is withdrawn. This is particularly true of women with focal epilepsy, where there may be safer, equally effective, alternative anti-seizure medication (ASM). The aim should be to create a partnership of trust between the patient and clinician in order to arrive at the best clinical decision for that individual

Audit of healthcare provision for UK prisoners with suspected epilepsy

SummaryPurposeTo describe the prevalence and nature of epileptic seizure disorders in a typical UK prison and compare the care offered to prisoners to the recommendations of the National Institute for Clinical Excellence (NICE).MethodsOver a 14-month period, all prisoners identified as having epilepsy were registered by prison primary healthcare services at a category ‘C’ prison holding 640 male adults. Prison and National Health Service health records were reviewed, prisoners were re-assessed by members of a specialist secondary care service based in the local general hospital NHS.ResultsTwenty-six prisoners were thought to have epilepsy. 61.5% of diagnoses had not been made by epilepsy specialists, 73.1% had uncontrolled seizures, only 19.2% had had computed tomography, none magnetic resonance imaging. At review, 30.8% of prisoners were thought to require neuroimaging, 19.2% cardiac investigations. The diagnosis of epilepsy was confirmed in only 57.9% of those prisoners considered to have the condition by prison healthcare services. 53.8% of those prisoners confirmed as having epilepsy had not had a medical review in the past 12 months; 63.2% required a change in their antiepileptic drugs (AEDs).ConclusionAlthough the prevalence of epilepsy in this prison population appeared high at first sight, a critical review of the diagnoses reduced the difference to the prevalence of epilepsy in the population at large. Fewer prisoners than expected achieved seizure control. Collaboration with specialist epilepsy services was poor. There were significant discrepancies between the healthcare provision in prison and the NICE epilepsy guidelines

Inferred support for disturbance-recovery hypothesis of North Atlantic phytoplankton blooms

Analyses of satellite-derived chlorophyll data indicate that the phase of rapid phytoplankton population growth in the North Atlantic (the ‘spring bloom') is actually initiated in the winter rather than the spring, contradicting Sverdrup's Critical Depth Hypothesis. An alternative disturbance-recovery hypothesis (DRH) has been proposed to explain this discrepancy, in which the rapid deepening of the mixed layer reduces zooplankton grazing rates sufficiently to initiate the bloom. We use Bayesian parameter inference on a simple Nutrient-Phytoplankton-Zooplankton (NPZ) to investigate the DRH and also investigate how well the model can capture the multiyear and spatial dynamics of phytoplankton concentrations and population growth rates. Every parameter in our NPZ model was inferred as a probability distribution given empirical constraints, this provides a more objective method to identify a model parameterisation given available empirical evidence, rather than fixing or tuning individual parameter values. Our model explains around 75% of variation in the seasonal dynamics of phytoplankton concentrations, 30% of variation in their population rates of change, and correctly predicts the phases of population growth and decline. Our parameter-inferred model supports DRH, revealing the sustained reduction of grazing due to mixed layer deepening as the driving mechanism behind bloom initiation, with the relaxation of nutrient limitation being another contributory mechanism. Our results also show that the continuation of the bloom is caused in part by the maintenance of phytoplankton concentrations below a level that can support positive zooplankton population growth. Our approach could be employed to formally assess alternative hypotheses for bloom formatio
