Abstract
Four representatives of the genus Lecithaster and one representative of the genus Hysterolecithoides were found during investigation of the trematode fauna of fish species in Vietnamese, Japanese and eastern coastal waters of the Russian Far East. Based on morphometric data, adult trematodes from Vietnamese Strongylura strongylura and Russian Acanthogobius flavimanus were identified as Lecithaster confusus, trematodes from Vietnamese Hemirhamphus marginatus as L. sayori and from osmerid fishes as L. salmonis. Further, a single specimen of Lecithaster sp. and representatives of Hysterolecithoides epinepheli were found in Vietnamese Siganus fuscescens. Morphological and molecular data, including 18S ribosomal DNA (rDNA) V4 fragment, 28S rDNA D1-D3 fragment, internal transcribed spacers (ITS) and a mitochondrial COI gene fragment were analysed for Lecithaster spp. The results revealed that L. sayori and L. salmonis are not synonyms of L. stellatus and L. gibbosus, respectively, but that Hysterolecithoides frontilatus and H. guangdongensis are junior synonyms of H. epinepheli. The 28S-rDNA-based phylogenetic tree of Hemiuroidea showed a distinct position for the genus Lecithaster with internal differentiation into three subclades, including L. confusus, L. sayori and Lecithaster sp. within the first subclade, L. mugilis and L. sudzuhensis within the second subclade and L. salmonis and L. gibbosus within the third subclade. Bayesian phylogenetic reconstructions of Hemiuroidea showed four clades for members of Hemiuridae and Lecithasteridae. The first clade consisted of Hemiuridae representatives and the second clade represented the genus Lecithaster. The third clade included genera Aponurus and Lecithophyllum (Lecithasteridae) and the fourth clade combined members of lecithasterid Quadrifoliovariinae and Hysterolecithinae and hemiurid Opisthadeninae and Bunocotylidae with high statistical support.
Under the Black Flag in Borno: experiences of foot soldiers and civilians in Boko Haram's ‘caliphate’
Authors: Pieri Zacharias P. , Zenn Jacob 
Published: November 2018

AbstractBoko Haram's operations and ideology have been the subject of increasing research in recent years. This article, in contrast, explores the culture of Boko Haram through an ethnographic analysis of the group's internal videos that were not intended for public release. The authors find that in their everyday lives Boko Haram foot soldiers are different from the image the group presents to the world in propaganda videos. While unmistakably a violent movement, in territories under the group's control that it attempted to administer, foot soldiers participated in conflict resolution with elders, explained the group's position on external alliances to villagers, engaged in recreation to pass time off the battlefield and created bonds of solidarity with other members of the group. Using insights from anthropology and the examination of ‘Jihadi Culture’, this article's insights help us understand how and why Boko Haram foot soldiers fight beyond the group's public ideology or stated goals: for many of them, it is simply a lifestyle.
The African Union and coercive diplomacy: the case of Burundi
Authors: Wilén Nina , Williams Paul D. 
Published: November 2018

AbstractIn December 2015, the African Union (AU) took the unprecedented step of threatening to use military force against the government of Burundi's wishes in order to protect civilians caught up in the country's intensifying domestic crisis. This article traces the background to this decision and analyses the effectiveness and credibility of the AU's use of coercive diplomacy as a tool of conflict management. After its usual range of conflict management tools failed to stem the Burundian crisis, the AU Commission and Peace and Security Council tried a new type of military compellence by invoking Article 4(h) of the Union's Constitutive Act. We argue that the threatened intervention never materialised because of (1) the Burundian government's astute diplomacy and (2) several African autocrats’ resistance to setting a precedent for future interventions where concerns about civilian protection might override state sovereignty.
Africa's role in the progression of international criminal justice: a moral and political argument
Authors: Fisher Kirsten J. 
Published: November 2018

AbstractGiven the history of the International Criminal Court in Africa, the relationship between African states and the Court is particularly significant to its legitimacy. If the power of the Court is grounded in international political support and the perception that it transcends international and national politics to deny impunity for ‘atrocity’ crimes, the Court's perceived legitimacy and normative legitimacy are so intertwined that charges of illegitimacy from significant regional stakeholders hold particular weight. More importantly, criticisms voiced by African actors point to a valid challenge to the Court's legitimate moral standing as an arbiter of global justice: the international power imbalance that seems to be becoming more entrenched and apparent in the Court's work. Tactics adopted by some African leaders of prioritising the issue of heads-of-state immunity, however, minimise the broader issue of power differentials and reduce the chance that African states will find allies in their cause to challenge the Court's operations.

Published: November 2018

AbstractBackgroundLiterature is lacking to guide standardised care and assessment practices for paediatric patients post cardiac catheterisation. In response to this gap, we sought to describe the current state of practice in cardiology programmes performing paediatric cardiac catheterisations procedures in the United States of America.Materials and methodsA web-based survey was distributed to the Congenital Cardiovascular Interventional Study Consortium Listserv, with representation from 113 identified institutions. A 36-question survey, including fixed-choice and open-ended questions, was developed and piloted for reliability and validity before distribution. Data were summarised descriptively with count and frequency or median and range.ResultsOf the 113 identified institutions, 52% (n=59) responded to the survey. Manual pressure is used to achieve haemostasis by 94.9% of the respondents. Pressure dressings are used by a majority of the facilities and the length of time for bed rest is variable, with the majority using 6 hours for arterial access and 4 hours for venous access. Predominantly, respondents use the time of haemostasis as the start time of bed rest while a third of respondents reported using the time the sheath was removed.ConclusionIn this study, variation in a number of post catheterisation care and assessment practices for paediatric patients was noted across cardiology programmes. Information from this assessment identifies key opportunities to collaborate in developing standardised practices for the care and assessment of the paediatric patients post catheterisation.

AbstractObjectiveThe present longitudinal study assessed whether changes in socio-economic status (SES) from infancy to adolescence were associated with plasma lipoprotein concentrations in adolescence, of which low HDL-cholesterol (HDL-C) and high LDL-cholesterol (LDL-C), TAG and total cholesterol (TC) concentrations are associated with higher cardiovascular risk.DesignSES, assessed using the modified Graffar Index, was calculated at 1, 5, 10 and 16 years. Principal components factor analysis with varimax rotation extracted two orthogonal SES factors, termed ‘environmental capital’ and ‘social capital’. Generalized linear models were used to analyse associations between environmental and social capital at 1 and 16 years and outcomes (HDL-C, LDL-C, TAG, TC) at 16 years, as well as changes in environmental and social capital from 1–5, 5–10, 10–16 and 1–16 years, and outcomes at 16 years.SettingSantiago, Chile.ParticipantsWe evaluated 665 participants from the Santiago Longitudinal Study enrolled at infancy in Fe-deficiency anaemia studies and examined every 5 years to age 16 years.ResultsSocial capital in infancy was associated with higher HDL-C in adolescence. Environmental capital in adolescence was associated with higher LDL-C and TC during adolescence. Changing environmental capital from 1–16 years was associated with higher LDL-C. Changing environmental capital from 1–5 and 1–16 years was associated with higher TC.ConclusionsImprovements in environmental capital throughout childhood were associated with less healthy LDL-C and TC concentrations in adolescence. We found no evidence of associations between changing environmental capital and HDL-C or TAG, or changing social capital and HDL-C, LDL-C, TAG or TC.

AbstractObjectiveTo assess salt intake and its dietary sources using biochemical and self-report methods and to characterize salt intake according to sociodemographic and disease-related variables in a sample of the Brazilian population.DesignPopulation-based cross-sectional survey.SettingSalt intake was assessed by biochemical (24 h urinary Na excretion) and self-report methods (sodium FFQ, 24 h dietary recall, seasoned-salt questionnaire, discretionary-salt questionnaire and total reported salt intake).ParticipantsAdults and older people (n 517) aged 20–80 years, living in Artur Nogueira, São Paulo, Brazil.ResultsMean salt intake based on 24 h urinary Na excretion and total reported salt intake was 10·5 and 11·0 g/d, respectively; both measures were significantly correlated. Discretionary salt and seasoned salt were the most important sources of salt intake (68·2 %). Men in the study consumed more salt than women as estimated by 24 h urinary Na excretion (11·7 v. 9·6 g salt/d; P<0·0001). Participants known to be hypertensive added more salt to their meals but consumed less salty ultra-processed foods. Waist circumference in both sexes and BMI were positively correlated with salt intake estimated by 24 h urinary Na excretion. In addition, regression analysis revealed that being a young male or having a high waist circumference was a predictor of higher salt intake.ConclusionsSalt intake in this population was well above the recommended amount. The main source of salt intake came from salt added during cooking. Salt intake varied according to sex and waist circumference.
Estimation of Vent Radii From Video Recordings and Infrasound Data Analysis: Implications for Vulcanian Eruptions From Sakurajima Volcano, Japan

Published: November 2018

AbstractWe estimated the vent radius within Showa Crater of Sakurajima volcano from ejection velocity and flow rate of gas‐particle mixtures. The ejection velocity was calculated from video recordings, and the flow rate and volume from infrasound data. Based on the assumption that the vent shape does not change during an explosion, the vent radius was estimated from 201 impulsive Vulcanian eruptions at Showa Crater, yielding values of 6.4–42.3 m (median 23.8 m), which is comparable with the width of fresh lava capping the vent, as photographed from a helicopter. Long‐term changes in vent radius (i.e., over several months) show a relationship with magma accumulation within a reservoir 2–5 km beneath the crater. If the top of the conduit is assumed to be cylindrical, then the vertical extent of the gas‐rich zone is estimated to be 120 m, which may reflect the depth of gas accumulation and buildup of significant overpressure.

AbstractWe characterized two sets of extensional faults that comprise the Nar Sulcus region of Ceres by applying a cantilever model for fault related flexure and derived flexural rigidity values for Nar Sulcus between 2.0 · 1015 and 1.8 · 1016 N·m. This range of flexural rigidity makes Nar Sulcus mechanically akin to extensional structures on Ganymede, Europa, and Enceladus. We combine these observations with an inferred strength profile for the upper mechanical layer of Ceres and estimate its thickness to be 2.9–9.5 km. Surface heat fluxes at Nar Sulcus during its formation were likely ≥10 mW/m2 for estimated strain rates of 10−17–10−14 s−1, which is at least one order of magnitude larger than the current estimated global average. For geologically plausible heat fluxes between 10 and 100 mW/m2, we estimate an upper bound of ~30 vol.% mechanically silicate‐like phases in the near surface at Nar Sulcus, neglecting the effects of porosity.
Nitrogen Content in the Earth's Outer Core

Published: November 2018

AbstractUsing first principles molecular dynamic simulations, we explore the effects of nitrogen (N) on the density and sound velocity of liquid iron and evaluate its potential as a light element in the Earth's outer core. Our results suggest that Fe‐N melt cannot simultaneously explain the density and seismic velocity of the Earth's outer core. Although ~2.0 wt.% N can explain the bulk sound velocity of the outer core, such N content only lowers the density of liquid Fe by ~3%. Matching both the velocity and density by the other light elements limits the N in the core to ≪2.0 wt.%. Our finding suggests that nitrogen is a minor to trace element in the Earth's core and is consistent with the geochemical mass balance with terrestrial abundance of N and alloy‐silicate partitioning data, which suggest that there cannot be significant N in the core.
Magmatic Triggering of Earthquakes on Distal Faults as a Potential Medium‐Term Warning Signal From Ruapehu Volcano
Authors: Hurst Tony , Kilgour Geoff , Hamling Ian 
Published: November 2018

AbstractA major eruption sequence of Ruapehu volcano began on 17 September 1995, with only hours of local precursory seismicity. However, from about 10 to 5 months prior to the eruption, an unusually high number of tectonic earthquakes occurred between 15 and 20 km west of Ruapehu. Diffusion chronometry of zoned crystals within erupted scoria from the 1995 eruptions of Ruapehu provide a petrological timescale of magmatic processes before the eruption. This timescale coincides with the seismicity to the west of Ruapehu. Stress modeling shows that stress changes due to movement of newly mixed magma from a sill under Ruapehu would have significantly added to the stress on preexisting faults, thereby providing a mechanism to explain the observed pre‐eruption seismicity. This shows that tectonic earthquakes in the vicinity of an active volcano may be an indication of magma movement and should be viewed as a possible eruption precursor.
Construction of the 500‐m Resolution Daily Global Surface Water Change Database (2001–2016)

Published: November 2018

AbstractSurface water is the most dynamic land‐cover type. Transitions between water and nonwater types (such as vegetation and ice) can happen momentarily. More frequent mapping is necessary to study the changing patterns of water. However, monitoring of long‐term global water changes at high spatial resolution and in high temporal frequency is challenging. Here we report the generation of a daily global water map data set at 500‐m resolution from 2001 to 2016 based on the daily reflectance time series from Moderate Resolution Imaging Spectroradiometer. Each single‐date image is classified into three types: water, ice/snow, and land. Following temporal consistency check and spatial‐temporal interpolation for missing data, we conducted a series of validation of the water data set. The producer's accuracy and user's accuracy are 94.61% and 93.57%, respectively, when checked with classification results derived from 30‐m resolution Landsat images. Both the producer's accuracy and user's accuracy reached better than 90% when compared with manually interpreted large‐sized sample units (≥1,000 m × 1,000 m) collected in a previous global land cover mapping project. Generally, the global inland water area reaches its maximum (~3.80 × 106 km2) in September and minimum (~1.50 × 106 km2) in February during an annual cycle. Short‐duration water bodies, sea level rise effects, different types of rice field use can be detected from the daily water maps. The size distribution of global water bodies is also discussed from the perspective of the number of water bodies and the corresponding water area. In addition, the daily water maps can precisely reflect water freezing and help correct water areas with inconsistent cloud flags in the MOD09GA quality assessment layer.
Determining and Modeling Dominant Processes of Interrill Soil Erosion
Authors: Zhang X. C. 
Published: November 2018

AbstractUnderstanding the dominant process of interrill soil erosion is imperative to better modeling interrill sediment delivery rates. The objectives are to (1) determine the limiting erosion process (detachment vs. transport) that controls interrill erosion under the study conditions, (2) quantify the effects of water and/or sediment influxes from upslope on downslope sediment transport and interrill erosion, and (3) evaluate the ability of commonly used hydraulic parameters for simulating interrill sediment delivery. Runoff, sediment delivery, and raindrop splash were simultaneously collected from two flumes (1.8 m × 0.5 m) and a 2.5‐cm slot between the flumes for three intensities of 60, 90, and 120 mm/hr at three slopes of 9%, 18%, and 27% under two cover treatments. Results showed that slot splash rates were consistently greater than flume wash rates, indicating that sediment transport capacity limited interrill sediment delivery under the study conditions. Soil detachment by raindrop impact was more influenced by surface water depth, while sediment transport capacity by flow velocity. The former played a bigger role in determining interill sediment delivery under detachment‐limited cases while the latter under transport‐limited conditions. Linear correlation coefficients between sediment delivery rates and hydraulic predictors were 0.545 for shear stress, 0.946 for stream power, 0.867 for unit stream power, and 0.948 for an empirical lumped model that includes a rainfall intensity term. Stream power and the empirical model were better predictors for interrill sediment delivery. However, their predictive abilities need to be assessed more rigorously at various impact levels of rainfall kinetic energy.

Published: November 2018

AbstractUnderstanding the factors that influence temporal variability in water quality is critical for designing water quality management strategies. In this study, we explore the key factors that affect temporal variability in stream water quality across multiple catchments using a Bayesian hierarchical model. We apply this model to a case study data set consisting of monthly water quality measurements obtained over a 20‐year period from 102 water quality monitoring sites in the state of Victoria (Southeast Australia). We investigate six water quality constituents: total suspended solids, total phosphorus, filterable reactive phosphorus, total Kjeldahl nitrogen, nitrate‐nitrite (NOx), and electrical conductivity. We find that same‐day streamflow has the greatest effect on water quality variability for all constituents. Additional important predictors include soil moisture, antecedent streamflow, vegetation cover, and water temperature. Overall, the models do not explain a large proportion of temporal variation in water quality, with Nash‐Sutcliffe coefficients lower than 0.49. However, when considering performance on a site‐by‐site basis, we see high model performance in some locations, with Nash‐Sutcliffe coefficients of up to 0.8 for NOx and electrical conductivity. The effect of the temporal predictors on water quality varies between sites, which should be explored further for potential spatial patterns in future studies. There is also potential for further extension of these temporal variability models into a predictive spatiotemporal model of riverine constituent concentrations, which will be a useful tool to inform decision making for catchment water quality management.
Spatial Variability of Groundwater Arsenic Concentration as Controlled by Hydrogeology: Conceptual Analysis Using 2‐D Reactive Transport Modeling
Authors: Jakobsen Rasmus , Kazmierczak Jolanta , Sø Helle Ugilt , Postma Dieke 
Published: November 2018

AbstractCombined geological, hydrogeological, and geochemical controls on the arsenic concentration of contaminated aquifers in SE Asia were explored by two‐dimensional (2‐D) reactive transport modeling of data sets from Bangladesh, Cambodia, and Vietnam. For each site, the field data are summarized and used to create a conceptual 2‐D reactive transport model that elucidates characteristic features influencing the groundwater arsenic concentration. Comparison of models for Bangladesh and Vietnam indicates that fine‐grained layers overlying young sandy aquifers generate shallow high arsenic groundwater because low vertical groundwater velocities allow sufficient time for kinetic As release from the sediment. The low vertical groundwater velocity below major river channels, predicted by the model, also creates long groundwater residence times, leading to high arsenic groundwater. Young aquifer sediments release more arsenic than older sediments, and alternating young and older sediments create complex patterns of high and low arsenic groundwater. Over time, floodplain basins will subside, and river channels migrate, causing sedimentation and erosion on the floodplain while creating local environments with evolving hydrogeology and groundwater geochemistry. We have developed a three‐step model for the evolution of the Red River floodplain with sedimentation and shifting channels over the last 6000 years. The results show comparable timescales between the dynamics of arsenic release and of river migration, causing complex groundwater As distributions, comprising geochemical palinopsia of long vanished rivers.
