Psychiatric sequelae of minor head injury. A prospective follow-up study
Authors: Middelboe T , Andersen HS , Birket-Smith M , Friis ML 
Published: April 2020

SummaryPsychiatric morbidity was measured in a prospective follow-up study of 51 patients admitted to hospital after minor head injury. By means of self report questionnaires (eg General Health Questionnaire (SHQ) and Impact of Event Scale), semistructured interviews and symptom-checklists, it was found that nearly half of the patients suffered considerable discomfort after 1 week. Improvement during the 3 months follow-up was generally poor. Both concussional symptoms and stress response contributed to the compromised well-being as measured by the GHQ, but outcome did not correlate to severity of injury. The GHQ-60 score of 1 week showed a strong positive correlation with outcome after 3 months. The incidence of post-traumatic stress disorder was low.

Abstract
Studies on community-acquired pneumonia (CAP) and pneumococcal pneumonia (PP) related to the 13-valent pneumococcal conjugate vaccine (PCV13) introduction in Asia are scarce. This study aimed to investigate the epidemiological and microbiological determinants of hospitalised CAP and PP after PCV13 was introduced in Japan. This observational hospital-based surveillance study included children aged ⩽15 years, admitted to hospitals in and around Chiba City, Japan. Participants had bacterial pneumonia based on a positive blood or sputum culture for bacterial pathogens. Serotype and antibiotic-susceptibility testing of Streptococcus pneumoniae and Haemophilus influenzae isolates from patients with bacterial pneumonia were assessed. The CAP hospitalisation rate per 1000 child-years was 17.7, 14.3 and 9.7 in children aged <5 years and 1.18, 2.64 and 0.69 in children aged 5–15 years in 2008, 2012 and 2018, respectively. There was a 45% and 41% reduction in CAP hospitalisation rates, between the pre-PCV7 and PCV13 periods, respectively. Significant reductions occurred in the proportion of CAP due to PP and PCV13 serotypes. Conversely, no change occurred in the proportion of CAP caused by H. influenzae. The incidence of hospitalised CAP in children aged ⩽15 years was significantly reduced after the introduction of PCV13 in Japan. Continuous surveillance is necessary to detect emerging PP serotypes.
The Politics of Removing Children: The International Tracing Service's German Foster Homes Investigation of 1948
Authors: Stone Dan 
Published: April 2020

AbstractAfter the Second World War, the International Tracing Service's Child Search Branch (CSB) responded to inquiries for missing children and, until 1950 when funding was stopped, searched for children ‘in the field’. As the Cold War set in, the US military authorities restricted the opportunities for such children, mostly Eastern European, to be removed from their German foster parents and returned to their countries of origin. In the spring of 1948, when tensions between the CSB fieldworkers and the military authorities were at their height, ITS appointed an experienced fieldworker, Charlotte Babinski, to investigate cases of children in German foster homes with a view to streamlining policy regarding child removal. Despite her findings, as monetary and geopolitical pressures increased, the CSB had to accept that many children of Eastern European origin would remain in Germany. Children were thus a battleground in the early Cold War, in which politics triumphed over ethics.
‘Habitually Embodied’ Memories: The Materiality and Physicality of Music in Hardy's Poetry
Authors: Charlwood Catherine 
Published: April 2020

This article reads Thomas Hardy's many musical instrument poems as the meeting point for the concerns of several critical fields: material culture, memory studies and the emerging interdisciplinary field of musical haptics. Close readings illuminate not only their relevance to such enquiries, but also how Hardy's manipulation of poetic form engenders a tactile musicality or ‘poetics of touch’ (as Marion Thain puts it). This article focuses on the aspects of these poems which have undergone least exploration: the depiction of the bodily effort involved in music-playing. While some of the poems are critical favourites (‘Old Furniture’) many of those studied here are routinely overlooked.A mnemonically-minded poet, Hardy wrote about the memories objects hold and the memories that may be mediated through them. For Hardy, the history of objects is inseparable from that of their now-dead owners: person and thing are tied together in memory. This is in part due to an object's inherent tangibility, and musical instruments are particularly tactile objects, benefiting from the further mnemonic of music itself.The core of the article considers Hardy's late poem ‘Haunting Fingers: A Phantasy in a Museum of Musical Instruments’, which hears instruments speak out their memories of being touched, and through memory feel ‘old muscles travel/Over their tense contours’. Revisions to the manuscript show Hardy removing ‘death’ and privileging instead the immediacy of remembered touch.Paying attention to the reading and note-taking Hardy did within nineteenth-century science, this article traces Hardy's imaginative explorations of the processes involved in playing musical instruments back to discoveries about the workings of the unconscious. Saleeby, James, Maudesley and Bastian informed Hardy's knowledge of the science behind music-playing, while musical haptics helps this study unpack why Hardy attends to the interactions which take place at the point of mechanical contact: finger to key, and to string.
Deciphering the landscape of international humanitarian law in the Asia-Pacific
Authors: Linton Suzannah 
Published: April 2020

AbstractThe 70th anniversary of the adoption of the Geneva Conventions on 12 August 1949 provided an opportunity for reflection on international humanitarian law (IHL). This article continues that reflection and presents some fresh scholarship about and from the Asia-Pacific region. The region's plurality leads to a complex and diverse landscape where there is no single “Asia-Pacific perspective on IHL” but there are instead many approaches and trajectories. This fragmented reality is, however, not a mess of incoherence and contradiction. In the following pages, the author argues for and justifies the following assessments. The first is that the norm of humanity in armed conflict, which underpins IHL, has deep roots in the region. This, to some extent, explains why there is no conceptual resistance to IHL, in the way that exists with the human rights doctrine. The second is that there has been meaningful participation of certain States from the region in IHL law-making. Thirdly, some Asia-Pacific States are among those actively contributing to the development of new or emerging areas relevant to IHL, such as outer space, cyberspace and the protection of the environment in armed conflict. This leads to the unavoidable issue of contradiction. How is it that in a region where such findings can be made (i.e., where there is discernible positivity towards the norm of humanity in armed conflict), there are so many armed conflicts with very serious IHL violations emerging? Should we reflect in a more nuanced way on “norm internalization” and “root causes”? These issues will be considered in the second section of the article. This examination leads to a third and final section, a concluding reflection on what all of this reveals about IHL in the Asia-Pacific. The real challenge for progressive humanitarianism, the author contends, is to traverse disciplines and to build on work done in, on and from the region in order to develop more informed and nuanced approaches to understanding the countries and societies of the region, moving on to study the process of norm internalization, and then developing creative and meaningful strategies for strengthening the links between that internalization, actual conduct on the ground, and norm socialization in the wider community.

Published: April 2020

Zusammenfassung. Informelle Argumente sind in wissenschaftlichen Texten allgegenwärtig. Um solche Argumente verstehen und bewerten zu können, müssen Studierende ihre Struktur entschlüsseln. Zur Erfassung dieser Kompetenz wurde der computergestützte Argumentstrukturtest (AST) für Studierende sozial- und erziehungswissenschaftlicher Fächer sowie Lehramtsstudierende entwickelt. Die Testpersonen lesen kurze Texte mit informellen Argumenten und identifizieren ihre funktionalen Komponenten (z. B. Behauptung, Begründung, Schlussregel). Anhand einer Stichprobe von 225 Studierenden wurde der AST einer ersten Überprüfung seiner Reliabilität und Validität unterzogen. Dabei erwies sich der AST als intern valide, mit einer breiten Streuung der Itemschwierigkeiten. In einem explanatorischen Item-Response-Modell konnten die Itemschwierigkeiten sehr präzise durch theoretisch relevante Itemmerkmale, die das Argumentverstehen beeinflussen, vorhergesagt werden. Korrelationen mit verbaler Intelligenz und Schul- und Studienleistungen sprechen darüber hinaus für die Kriteriumsvalidität des Instruments.

Zusammenfassung. Der in der TEDS-M-Studie (Teacher Education and Development Study: Learning to Teach Mathematics) entwickelte Test zur Erfassung pädagogischen Wissens am Ende der Lehramtsausbildung hat sich in diversen Untersuchungen als zuverlässiges Messinstrument erwiesen, für das eine Reihe von Ergebnissen vorliegt, die die Validität der Testwertinterpretationen bei (angehenden) Lehrkräften in unterschiedlichen Ausbildungsstadien und –kontexten unterstreichen. Ein wesentlicher Validierungsschritt steht jedoch noch aus: Die Überprüfung, ob sich der Test eignet, um quantitative und qualitative Aussagen zum pädagogischen Wissen von berufstätigen Mathematiklehrkräften zu treffen. Im Rahmen des Projekts TEDS-Validierung wurde an 113 Mathematiklehrkräften geprüft, ob der Test das Wissen der Lehrkräfte reliabel und differenziert erfasst. Darauf aufbauend wurde im Sinne der Konstruktrepräsentation ( Embretson, 1983 ) untersucht, ob er konstruktrelevante, kognitive Bearbeitungsprozesse erfordert, wie sie von König (2009) und Klemenz und König (2019) modelliert wurden. Die Analysen bestätigen, dass der Test auch bei berufstätigen Mathematiklehrkräften ein reliables Messinstrument darstellt und unterstreichen, dass die kognitive Komplexität der erforderlichen Bearbeitungsprozesse einen bedeutsamen Anteil der Schwierigkeitsvarianz aufklärt. Sie liefern somit einen ersten Hinweis für die Konstruktrepräsentation und die Grundlage für eine qualitative Interpretation der Testwerte. Diese Interpretation wird durch Varianzanalysen validiert, die zeigen, dass Personen, die kognitiv komplexere Bearbeitungsprozesse im pädagogischen Wissenstest vollziehen können, auch ausgeprägtere situationsspezifische, pädagogische Fähigkeiten aufweisen als Vergleichspersonen.

AbstractFully coupled climate models have long shown a wide range of Antarctic sea ice states and evolution over the satellite era. Here, we present a high‐level evaluation of Antarctic sea ice in 40 models from the most recent phase of the Coupled Model Intercomparison Project (CMIP6). Many models capture key characteristics of the mean seasonal cycle of sea ice area (SIA), but some simulate implausible historical mean states compared to satellite observations, leading to large intermodel spread. Summer SIA is consistently biased low across the ensemble. Compared to the previous model generation (CMIP5), the intermodel spread in winter and summer SIA has reduced, and the regional distribution of sea ice concentration has improved. Over 1979–2018, many models simulate strong negative trends in SIA concurrently with stronger‐than‐observed trends in global mean surface temperature (GMST). By the end of the 21st century, models project clear differences in sea ice between forcing scenarios.
Sea Ice Roughness Overlooked as a Key Source of Uncertainty in CryoSat‐2 Ice Freeboard Retrievals

Published: April 2020

AbstractESA's CryoSat‐2 has transformed the way we monitor Arctic sea ice, providing routine measurements of the ice thickness with near basin‐wide coverage. Past studies have shown that uncertainties in the sea ice thickness retrievals can be introduced at several steps of the processing chain, for instance, in the estimation of snow depth, and snow and sea ice densities. Here, we apply a new physical model to CryoSat‐2, which further reveals sea ice surface roughness as a key overlooked feature of the conventional retrieval process. High‐resolution airborne observations demonstrate that snow and sea ice surface topography can be better characterized by a lognormal distribution, which varies based on the ice age and surface roughness within a CryoSat‐2 footprint, than a Gaussian distribution. Based on these observations, we perform a set of simulations for the CryoSat‐2 echo waveform over “virtual” sea ice surfaces with a range of roughness and radar backscattering configurations. By accounting for the variable roughness, our new lognormal retracker produces sea ice freeboards that compare well with those derived from NASA's Operation IceBridge airborne data and extends the capability of CryoSat‐2 to profile the thinnest/smoothest sea ice and thickest/roughest ice. Our results indicate that the variable ice surface roughness contributes a systematic uncertainty in sea ice thickness of up to 20% over first‐year ice and 30% over multiyear ice, representing one of the principal sources of pan‐Arctic sea ice thickness uncertainty.

AbstractWith nearly 1 million observations of column‐mean carbon dioxide concentration (X) per day, the Orbiting Carbon Observatory 2 (OCO‐2) presents exciting possibilities for monitoring the global carbon cycle, including the detection of subcontinental column CO2variations. While the OCO‐2 data set has been shown to achieve target precision and accuracy on a single‐sounding level, the validation of Xspatial gradients on subcontinental scales remains challenging. In this work, we investigate the use of an integrated path differential absorption (IPDA) lidar for evaluation of OCO‐2 observations via NASA's Atmospheric Carbon and Transport (ACT)‐America project. The project has completed eight clear‐sky underflights of OCO‐2 with the Multifunctional Fiber Laser Lidar (MFLL)—along with a suite of in situ instruments—giving a precisely colocated, high‐resolution validation data set spanning nearly 3,800 km across four seasons. We explore the challenges and opportunities involved in comparing the MFLL and OCO‐2 Xdata sets and evaluate their agreement on synoptic and local scales. We find that OCO‐2 synoptic‐scale gradients generally agree with those derived from the lidar, typically to ±0.1 ppm per degree latitude for gradients ranging in strength from 0 to 1 ppm per degree latitude. CO2reanalysis products also typically agree to ±0.25 ppm per degree when compared with an in situ‐informed CO2“curtain.” Real Xfeatures at local scales, however, remain challenging to observe and validate from space, with correlation coefficients typically below 0.35 between OCO‐2 and the MFLL. Even so, ACT‐America data have helped investigate interesting local Xpatterns and identify systematic spurious cloud‐related features in the OCO‐2 data set.
Evidence for Horizontal Blocking and Reflection of a Small‐Scale Gravity Wave in the Mesosphere

AbstractThe variations of the horizontal phase velocity of an internal gravity wave, generated by wave “blocking” or “reflection” due to an inhomogeneous wind field, have been predicted theoretically and numerically investigated but had yet to be captured experimentally. In this paper, through a collaborative observation campaign using a sodium (Na) Temperature/Wind lidar and a collocated Advanced Mesospheric Temperature Mapper (AMTM) at Utah State University (USU), we report the first potential evidence of such a unique gravity wave process. The study shows that a small‐scale wave, captured by the AMTM, with initial observed horizontal phase velocity of 37 ± 5 m/s toward the northwest direction, experienced a large and increasing headwind as it was propagating in the AMTM field of view. This resulted in significant deceleration along its initial traveling direction, and it became quasi‐stationary before it was “reflected” to the opposite direction at later time. The USU Na lidar measured the horizontal wind and temperature during the event, when the wave was found traveling within a temperature inversion layer and experiencing an increasing headwind relative to the wave. The wind agrees well with the expected value for wave blocking suggested by the wave tracing theory, implying the existence of a large horizontal wind gradient that night near the OH layer altitudes. The study indicates the critical role of horizontal winds and their horizontal gradients in determining propagation in vertical and horizontal directions.
A Retrospective of Findings From the FORTE Satellite Mission
Authors: Light T. E. L. 
Published: April 2020

AbstractWe revisit the findings from the FORTE satellite program (1997–2004), which collected optical imaging of lightning as well as optical and radio frequency time series waveforms globally from low‐earth‐orbit. These include surveys of the earth's radio frequency anthropogenic noise environment; earth surface reflectivity at radio frequencies; a scheme for classifying lightning discharge types on the basis of their very high frequency time domain power envelope; insights into the polarization and radiation pattern characteristics of different lightning types, with implications for the underlying discharge processes; and estimates of cloud optical properties based on the statistics of scattered light. Most significantly, FORTE was uniquely suited to capture large samples of data from the rare discharge known as “narrow bipolar events,” enabling detailed examination of their basic characteristics and confirming that they appear to result from fundamentally distinct physical processes compared to other lightning. In particular, despite representing huge charge transfer they evidently produce little‐to‐no light output.
Tuning the MPI‐ESM1.2 Global Climate Model to Improve the Match With Instrumental Record Warming by Lowering Its Climate Sensitivity
Authors: Mauritsen Thorsten , Roeckner Erich 
Published: April 2020

AbstractA climate model's ability to reproduce observed historical warming is sometimes viewed as a measure of quality. Yet, for practical reasons it cannot be considered a purely empirical result of the modeling efforts because the desired result is known in advance and so is a potential target of tuning. Here we report how the latest edition of the Max Planck Institute for Meteorology Earth System Models (MPI‐ESM1.2) atmospheric component (ECHAM6.3) had its sensitivity systematically tuned in order to improve the modeled match with the instrumental record. In practice, this was done by targeting an equilibrium climate sensitivity of about 3 K, slightly lower than in the previous model generation (MPI‐ESM), which warmed more than observed, and in particular by addressing a climate sensitivity of about 7 K in an intermediate version of the model. In the process we identified several controls on cloud feedback, some of which confirm recently proposed hypotheses. We find the model exhibits excellent fidelity with the observed centennial global warming. We further find that an alternative approach with high climate sensitivity compensated by strong aerosol cooling instead would yield colder than observed results in the second half of the twentieth century.
Contrasting Scale Dependence of Entrainment‐Mixing Mechanisms in Stratocumulus Clouds

Published: April 2020

AbstractThe apparent turbulent entrainment‐mixing mechanism between clouds and surrounding air is scale dependent; however, such scale dependence has been rarely studied, hindering development of scale‐aware entrainment‐mixing parameterizations. Here we extend our previous study on cumulus clouds to investigate scale dependence of entrainment‐mixing processes in stratocumulus clouds during Aerosol and Cloud Experiments in Eastern North Atlantic and Routine AAF (Atmospheric Radiation Measurement (ARM) Aerial Facility) Clouds with Low Optical Water Depths (CLOWD) Optical Radiative Observations (RACORO). In contrast to previous studies, two opposite scale dependencies are found: Entrainment mixing can become more homogeneous or more inhomogeneous with increasing averaging scales, which is quantified by the difference between homogeneous mixing degree at the 100 and 10 m resolutions. A new heuristic model and two new quantities are introduced. The observations and model show that microphysical properties near and far away from droplet‐free air and relative humidity of entrained air determine both the sign and strength of scale dependence, while droplet‐free air fraction only affects the strength. The results shed new light on developing scale‐aware parameterizations of entrainment‐mixing mechanisms.
Where Resource‐Acquisitive Species Are Located: The Role of Habitat Heterogeneity
Authors: Seyednasrollah Bijan , Clark James S. 
Published: April 2020

AbstractRising temperatures with increased drought pose two challenges for management of future biodiversity. First, are the most vulnerable species concentrated in specific regions and habitats? Second, where can landscape heterogeneity potentially mitigate impacts? We conducted a comprehensive trait analysis of forest plots spanning the eastern United States to quantify how resource‐acquisitive species respond to moisture‐soil‐climate interactions. We found that resource‐acquisitive species, including nutrient‐acquisitive and moisture‐acquisitive species, respond disproportionately to environmental gradients, and their response is largely explained by soil variation. We showed that the strong boundary of resource‐acquisitive species occurs near the last glacial limit, highlighting one of the clearest indicators of soil controls. Although local soil moisture may reduce drought‐induced stress for moisture‐acquisitive species, nutrient‐acquisitive species remain vulnerable on wet soils in dry climates. The results suggest that theories explaining species distributions should devote close attention to the combination of local drainage and soil type.
