Starting Big: The Effect of Unit Size on Language Learning in Children and Adults
Authors: HAVRON Naomi , ARNON Inbal 
Published: June 2020

AbstractMultiword units play an important role in language learning and use. It was proposed that learning from such units can facilitate mastery of certain grammatical relations, and that children and adults differ in their use of multiword units during learning, contributing to their varying language-learning trajectories. Accordingly, adults learn gender agreement better when encouraged to learn from multiword units. Previous work has not examined two core predictions of this proposal: (1) that children also benefit from initial exposure to multiword units, and (2) that their learning patterns reflect a greater reliance on multiword units compared to adults. We test both predictions using an artificial-language. As predicted, both children and adults benefit from early exposure to multiword units. In addition, when exposed to unsegmented input – adults show better learning of nouns compared to article-noun pairings, but children do not, a pattern consistent with adults’ predicted tendency to focus less on multiword units.

Abstract
Circulation of multiple dengue virus (DENV) serotypes in a locale has resulted in individuals becoming infected with mixed serotypes. This research was undertaken to study the clinical presentation, presence of DENV serotypes and serological characteristics of DENV infected patients with co-infections from three Provinces of Sri Lanka where DENV-1 and -2 predominated during the study. A reverse transcription polymerase chain reaction was performed on 1249 patient samples and 301 were positive for DENV (24.1%). DENV-1 was the predominant serotype detected in 137 (45.51%) followed by DENV-2 in 65 (21.59%), DENV-3 in 59 (19.6%) and DENV-4 in 4 (1.32%) patients with mono-infections. Thirty-three patients (10.96%) had DENV co-infections with two or more serotypes. The highest number of co-infections was noted between DENV-1 and DENV-2 (57.57%) suggesting co-infection is driven by the frequency of the circulating serotypes. Platelet counts were significantly higher in DENV co-infected patients although clinical disease severity or white blood cell count, packed cell volume or viraemia were not significantly different in the co-infected compared to the mono-infected patients. Thus co-infection with multiple DENV serotypes does occur but with the exception of improved platelet counts in co-infected patients, there is no evidence that clinical or laboratory measures of disease are altered.

Abstract

Objective
A continuous survey on influenza was conducted in Hulunbuir, China from January 2010 to May 2019 to reveal epidemiological, microbiological and air pollutants associated with laboratory-confirmed influenza cases.

Methods
Influenza-like illness and severe acute respiratory infection subjects were enrolled from a sentinel hospital in Hulunbuir during the study period for epidemiological and virological investigation. The association between air pollutants and influenza-positivity rate was assessed by a generalised additive model.

Results
Of 4667 specimens, 550 (11.8%) were tested positive for influenza. The influenza-positivity was highest in the age groups of 5–14 years, 50–69 years and ⩾70 years. We found that the effect of particulate matter ⩽2.5 μm (PM2.5) concentrations on the influenza-positivity rate was statistically significant, particularly on day lag-4 and lag-5. Genetic characterisations showed that (H1N1) pdm09 strains belonged to subclade 6B.1 and that influenza B isolates belonged to subclade 1A-3Del, with significant substitutions in the haemagglutinin and neuraminidase proteins compared with those in the WHO-recommended vaccine strains.

Conclusions
Elderly individuals and school-age children were at high risk for influenza infection. PM2.5 concentrations showed significant effects on influenza-positivity rate in Hulunbuir, which could be considered in local influenza prevention strategies.
Callous-unemotional traits in youth with autism spectrum disorder (ASD): replication of prevalence estimates and associations with gaze patterns when viewing fearful faces

AbstractResearch suggests an increased prevalence of callous-unemotional (CU) traits in children with autism spectrum disorder (ASD), and a similar impairment in fear recognition to that reported in non-ASD populations. However, past work has used measures not specifically designed to measure CU traits and has not examined whether decreased attention to the eyes reported in non-ASD populations is also present in individuals with ASD. The current paper uses a measure specifically designed to measure CU traits to estimate prevalence in a large community-based ASD sample. Parents of 189 adolescents with ASD completed questionnaires assessing CU traits, and emotional and behavioral problems. A subset of participants completed a novel emotion recognition task (n = 46). Accuracy, reaction time, total looking time, and number of fixations to the eyes and mouth were measured. Twenty-two percent of youth with ASD scored above a cut-off expected to identify the top 6% of CU scores. CU traits were associated with longer reaction times to identify fear and fewer fixations to the eyes relative to the mouth during the viewing of fearful faces. No associations were found with accuracy or total looking time. Results suggest the mechanisms that underpin CU traits may be similar between ASD and non-ASD populations.
The cognitive status of metalinguistic knowledge in speakers of one or more languages
Authors: Smith Michael Sharwood 
Published: June 2020

AbstractThe term ‘metalinguistic’ is used to define the kind of ability whereby people for various purposes view language as an object. It is strongly associated with consciousness and touches on many aspects of literacy, multilingualism and language acquisition. Discussions in the research literature have generally been on specific aspects of metalinguistic knowledge: the time is ripe for a more fundamental reassessment focusing on how exactly metalinguistic ability is represented and processed on line, and how it fits in with other kinds of representation and processing. To this end, a particular theoretical perspective that takes into account contemporary research in cognitive science, the Modular Cognition Framework, will be applied with the aim of supporting further empirical investigations into this area of language ability and locating it within an integrated approach to cognition in general. Finally, the usefulness of metalinguistic knowledge will be briefly considered.

Published: June 2020

AbstractObjective:This study examined psychological constructs (delay discounting, grit, future time perspective and subjective social status) in relation to food security status and body weight.Design:A simultaneous triangulation mixed methods design was used to collect quantitative and qualitative data. Quantitative data were collected in fifty-six adults. Independent variables included food security status (food secure or food insecure) and BMI category (normal weight or overweight/obese). Participants, matched on race (African American and White), were categorised into four food security status by BMI category groups. Psychological constructs were measured via validated questionnaires. Qualitative data were collected in a subsample of twelve participants via in-depth interviews.Setting:This study was conducted in Baton Rouge, Louisiana.Participants:The sample was 66 % female and 48 % African American with a mean age of 32·3 (sd9·2) years and BMI of 28·8 (sd7·7) kg/m2.Results:Quantitative results showed that food-insecure participants with overweight/obesity had greater delay discounting (–3·78v. –6·16,P= 0·01; –3·78v. –5·75,P= 0·02) and poorer grit (3·37v. 3·99,P= 0·02; 3·37v. 4·02,P= 0·02 ) than their food-secure counterparts and food-insecure participants with normal weight. Food-insecure participants with overweight/obesity also had a shorter time period for financial planning (0·72v. 4·14,P= 0·02) than food-secure participants with normal weight. Qualitative data largely supported quantitative findings with participants discussing varied perceptions of psychological constructs.Conclusions:This study found differences in delaying gratification, grit and financial planning between food security status and body weight groups.

Published: June 2020

AbstractObjective:To assess trends in consumption of soda, sweetened fruit drinks/sports drinks and any sugar-sweetened beverage (SSB) from 2013 to 2016 among all children in California aged 2–5 and 6–11 years and by racial-ethnic group.Design:Serial cross-sectional study using the California Health Interview Survey (CHIS).Setting:CHIS is a telephone survey of households in California designed to assess population-level estimates of key health behaviours. Previous research using CHIS documented a decrease in SSB consumption among children in California from 2003 to 2009 coinciding with state-level policy efforts targeting child SSB consumption.Participants:Parents of children in California aged 2–11 years (n 4901 in 2013–2014; n 3606 in 2015–2016) were surveyed about the child’s consumption of soda and sweetened fruit drinks/sports drinks on the day prior.Results:Among 2–5-year-olds, consumption of soda, sweetened fruit drinks/sports drinks and any SSB remained stable. Sweetened fruit drink/sports drink consumption was higher than soda consumption in this age group. Latino 2–5- year-olds were more likely to consume any SSB in both 2013–2014 and 2015–2016 compared with Whites. Among 6–11-year-olds, consumption of soda, sweetened fruit drinks/sports drinks and any SSB also remained stable over time. Latino and African-American 6–11-year-olds were more likely to consume an SSB in 2013–2014 compared with White children.Conclusions:SSB consumption among children in California was unchanged from 2013 to 2016 and racial-ethnic disparities were evident. Increased policy efforts are needed to further reduce SSB consumption, particularly among children of Latino and African-American backgrounds.
Party decline or social transformation? Economic, institutional and sociological change and the rise of anti-political-establishment parties in Western Europe
Authors: Casal Bértoa Fernando , Rama José 
Published: June 2020

AbstractThe rise in support for anti-political-establishment parties (APEp), especially since the beginning of the 2008 Great Recession, has put democracy in peril. Some scholars have warned us about the negative implications the recent rise of APEp might have for the development of democracy in Western Europe. For that reason, it is important we begin to understand what generates APEp’s electoral success. Drawing on a new comparative dataset that examines all Western European democracies from 1849 until 2017, the current article attempts to provide an explanation. In particular, our analyses examine three alternative explanations put forward by the literature: economic, institutional, and sociological. Our results show that it is not economic performance but both institutional and sociological change which together can help to understand the current wave of support for APEp.
Regulating Emotion Systems in Everyday Life

Abstract. Researchers are increasingly using ecological momentary assessment (EMA) to investigate how people regulate their emotions from moment-to-moment in daily life. However, existing self-report measures of emotion regulation have been designed and validated to assess habitual/trait use of emotion regulation strategies and may therefore not be suited to assessing momentary emotion regulation. The present study aimed to develop a brief, yet reliable, EMA measure of emotion regulation in daily life by adapting the Regulation of Emotion Systems Survey (RESS; DeFrance & Hollenstein, 2017 ), a recently developed global self-report questionnaire assessing habitual use of six emotion regulation strategies. We created an EMA version of the RESS by selecting 12 items from the original scale and adapting them for EMA. We investigated the psychometric properties of the new RESS-EMA scale by administering it eight times daily for 7 days via smartphones to a sample of undergraduates ( n = 112). Results of multilevel modeling analyses supported the within- and between-person reliability and validity of the RESS-EMA scale and suggest that it is a viable way to comprehensively assess momentary emotion regulation strategy use in daily life.

Published: June 2020

AbstractRadar rainfall nowcasting, the process of statistically extrapolating the most recent rainfall observation, is increasingly used for very short range rainfall forecasting (less than 6 hr ahead). We performed a large‐sample analysis of 1,533 events, systematically selected for 4 event durations and 12 lowland catchments (6.5–957 km2), to determine the predictive skill of nowcasting. Four algorithms are tested and compared with Eulerian Persistence: Rainymotion Sparse, Rainymotion DenseRotation, Pysteps deterministic, and Pysteps probabilistic with 20 ensemble members. We focus on the dependency of nowcast skill on event duration, season, catchment size, and location. Maximum skillful lead times increase for longer event durations, due to the more persistent character of these events. For all four event durations, Pysteps deterministic attains the longest average decorrelation times, with 25 min for 1‐hr durations, 40 min for 3 hr, 56 min for 6 hr, and 116 min for 24 hr. During winter, with more persistent stratiform precipitation, we find three times lower mean absolute errors than for convective summer precipitation. Higher skill is also found after spatially upscaling the forecast. Catchment location matters too: Given the prevailing storm movement, two times higher skillful lead times are found downwind than upwind toward the edge of the domain. In most cases, Pysteps algorithms outperform the Rainymotion benchmark algorithms. We speculate that most errors originate from growth and dissipation processes which are not or only partially (stochastically) accounted for.
Structural Controls on Slope Failure Within the Western Santa Barbara Channel Based on 2‐D and 3‐D Seismic Imaging
Authors: Kluesner Jared W. , Brothers Daniel S. , Wright Alexis L. , Johnson Samuel Y. 
Published: June 2020

AbstractThe Santa Barbara Channel, offshore California, contains several submarine landslides and ample evidence for incipient failure. This region hosts active thrust and reverse faults that accommodate several mm/yr of convergence, yet the relationships between tectonic deformation and slope failure remain unclear. We present 3‐D and 2‐D multichannel seismic reflection (MCS) data sets, multibeam bathymetry, and chronostratigraphic constraints to investigate the controls on slope failure. Splay faulting along the North Channel Deformation Trend (NCDT) coincides with a distinct zone of compressional uplift and onlapping of steeply dipping Quaternary strata. The NCDT is spatially correlated with seafloor fissures, and 3‐D seismic analyses reveal an intricate system of en echelon reverse faults that offset sediments younger than ~25 ka. Localized uplift zones are located between faults, one of which underlies the Gaviota landslide headscarp. We observe a direct relationship between slope failure and along‐strike variations in the tectonostratigraphic framework. Based on geophysical properties at Ocean Drilling Program (ODP) Site 893, we predict a trend in compaction and porosity reduction in the basin that drives pore fluids up‐dip, toward the zone of onlap above the NCDT, thus reducing slope stability. This interplay between tectonic, sedimentary, and fluid‐flow processes along the NCDT has created a confluence of preconditioning factors, with Gaviota and Goleta landslides being distinguished from the surrounding slopes by their position above the NCDT. The distribution of seafloor fissures suggests sections of the slope remain unstable and are prone to future landsliding. These results provide insights into the processes and 3‐D feedbacks that lead to slope instability along other convergent margins.

AbstractObservations of far‐ultraviolet (FUV) dayglow by the Global‐scale Observations of Limb and Disk (GOLD) mission provide a new opportunity for determining how geomagnetic storms alter the temperature of the thermosphere and enable us to quantify the global‐scale response of the thermosphere to solar extreme‐ultraviolet (EUV) variability. Relative temperature changes can be measured by monitoring changes in the scale height of molecular nitrogen as observed in Lyman‐Birge‐Hopfield (LBH) band emissions. Mean scale heights are derived from GOLD FUV observations using Chapman function fits to altitude profiles of LBH band emissions. We provide an overview of the theoretical basis for the GOLD Level 2 exospheric temperature algorithm, including a generalization of a standard Chapman function fitting technique to allow for gravity and temperature gradients. Effects on derived exospheric temperatures from instrument artifacts and stars in the GOLD field of view are reviewed. We also discuss GOLD Level 1C LIM and Level 2 TLIMB data products and present representative examples of each. We show that exospheric temperatures vary with local time and correlate weakly with solar activity but more strongly with geomagnetic activity. Finally, we present results from a preliminary data product validation that show good qualitative agreement with predictions from a global reference atmospheric model.
Microcontinents and Continental Fragments Associated With Subduction Systems
Authors: van den Broek J. M. , Gaina C. 
Published: June 2020

AbstractMicrocontinents and continental fragments are small pieces of continental crust that are surrounded by oceanic lithosphere. Although classically associated with passive margin formation, here we present several preserved microcontinents and continental fragments associated with subduction systems. They are located in the Coral Sea, South China Sea, central Mediterranean and Scotia Sea regions, and a “proto‐microcontinent,” in the Gulf of California. Reviewing the tectonic history of each region and interpreting a variety of geophysical data allows us to identify parameters controlling the formation of microcontinents and continental fragments in subduction settings. All these tectonic blocks experienced long, complex tectonic histories with an important role for developing inherited structures. They tend to form in back‐arc locations and separate from their parent continent by oblique or rotational kinematics. The separated continental pieces and associated marginal basins are generally small and their formation is quick (<50 Myr). Microcontinents and continental fragments formed close to large continental masses tend to form faster than those created in systems bordered by large oceanic plates. A common triggering mechanism for their formation is difficult to identify, but seems to be linked with rapid changes of complex subduction dynamics. The young ages of all contemporary pieces found in situ suggest that microcontinents and continental fragments in these settings are short lived. Although presently the amount of in‐situ subduction‐related microcontinents is meager (an area of 0.56% and 0.28% of global, non‐cratonic, continental crustal area and crustal volume, respectively), through time microcontinents contributed to terrane amalgamation and larger continent formation.

AbstractBackgroundExecutive function deficits in children born very preterm (VPT) have been linked to anatomical abnormalities in white matter and subcortical brain structures. This study aimed to investigate how altered brain metabolism contributes to these deficits in VPT children at school-age.MethodsFifty-four VPT participants aged 8–13 years and 62 term-born peers were assessed with an executive function test battery. Brain metabolites were obtained in the frontal white matter and the basal ganglia/thalami, using proton magnetic resonance spectroscopy (MRS).N-acetylaspartate (NAA)/creatine (Cr), choline (Cho)/Cr, glutamate + glutamine (Glx)/Cr, and myo-Inositol (mI)/Cr were compared between groups and associations with executive functions were explored using linear regression.ResultsIn the frontal white matter, VPT showed lower Glx/Cr (mean difference: −5.91%, 95% CI [−10.50, −1.32]), higher Cho/Cr (7.39%, 95%-CI [2.68, 12.10]), and higher mI/Cr (5.41%, 95%-CI [0.18, 10.64]) while there were no differences in the basal ganglia/thalami. Lower executive functions were associated with lower frontal Glx/Cr ratios in both groups (β = 0.16,p = 0.05) and higher mI/Cr ratios in the VPT group only (interaction:β = −0.17,p = 0.02).ConclusionLong-term brain metabolite alterations in the frontal white matter may be related to executive function deficits in VPT children at school-age.ImpactVery preterm birth is associated with long-term brain metabolite alterations in the frontal white matter.Such alterations may contribute to deficits in executive function abilities.Injury processes in the brain can persist for years after the initial insult.Our findings provide new insights beyond structural and functional imaging, which help to elucidate the processes involved in abnormal brain development following preterm birth.Ultimately, this may lead to earlier identification of children at risk for developing deficits and more effective interventions.
