THE ASSOCIATIONS BETWEEN IMPLICIT AND EXPLICIT LANGUAGE APTITUDE AND THE EFFECTS OF THE TIMING OF CORRECTIVE FEEDBACK
Authors: Fu Mengxia , Li Shaofeng 
Published: May 2021

AbstractThis study examines the associations between implicit and explicit language aptitude and the effects of the timing of corrective feedback (CF). A total of 112 seventh-grade EFL learners were assigned to three groups: Immediate CF, Delayed CF, and Task Only. The three groups underwent three treatment sessions during which they performed six focused communicative tasks eliciting the use of the English past tense. The Immediate and Delayed CF groups received CF treatments in the first and final sessions, respectively, and the Task Only group performed the communicative tasks without receiving any feedback. Treatment effects were measured through an untimed grammaticality judgment test and an elicited imitation test. Implicit language aptitude was operationalized as procedural memory and explicit language aptitude as working memory and declarative memory. Multiple regression analysis showed that procedural memory was significantly predictive of the effectiveness of Immediate CF, declarative memory was significantly associated with Delayed CF and Task Only, and working memory was a significant predictor of Immediate CF and Delayed CF. The results were interpreted by consulting the methodological features of the treatments and the mechanisms of the three cognitive abilities.
Thue equations that simultaneously fail the Hasse principle
Authors: BENGOECHEA PALOMA 
Published: May 2021

AbstractWe refine a previous construction by Akhtari and Bhargava so that, for every positive integer m, we obtain a positive proportion of Thue equations F(x, y) = h that fail the integral Hasse principle simultaneously for every positive integer h less than m. The binary forms F have fixed degree ≥ 3 and are ordered by the absolute value of the maximum of the coefficients.
Implementing UNESCO’s Convention on Cultural Diversity at the regional level: Experiences from evaluating cultural competence centers
Authors: Betzler Diana 
Published: May 2021

AbstractThis article deals with the question of whether regional cultural competence centers foster the diversity of cultural expressions and how the objectives of the United Nations Educational, Scientific, and Cultural Organization’s (UNESCO) Convention on Cultural Diversity are implemented. By introducing the Convention on Cultural Diversity, the conditions of regional cultural policy governance, and the idea of regional cultural competence centers, a framework for evaluation is outlined. The evaluation of four regional cultural competence centers in the Swiss Central Region shows that fostering cultural diversity is complex and has many different approaches and effects. The final discussion concludes that principles such as “interculturality,” “freedom,” and “access for all” under the Convention on Cultural Diversity can promote a diversity of cultural expressions but that these criteria have to be set from outside—for example, by public funding institutions—so that regional actors implement them.

AbstractThe cognitive control system matures gradually with age and shows age-related sex differences. To gain knowledge concerning error adaptation in familial high-risk groups, investigating error adaptation among the offspring of parents with severe mental disorders is important and may contribute to the understanding of cognitive functioning in at-risk individuals. We identified an observational cohort through Danish registries and measured error adaptation using an Eriksen flanker paradigm. We tested 497 7-year-old children with a familial high risk of schizophrenia (N = 192) or bipolar disorder (N = 116) for deficits in error adaptation compared with a control group (N = 189). We investigated whether error adaptation differed between high-risk groups compared with controls and sex differences in the adaptation to errors, irrespective of high-risk status. Overall, children exhibited post-error slowing (PES), but the slowing of responses did not translate to significant improvements in accuracy. No differences were detected between either high-risk group compared with the controls. Boys showed less PES and PES after incongruent trials than girls. Our results suggest that familial high risk of severe mental disorders does not influence error adaptation at this early stage of cognitive control development. Error adaptation behavior at age 7 years shows specific sex differences.
Management of life-threatening flecainide overdose: a case report of an infant
Authors: Tuncer T. 
Published: May 2021

AbstractFlecainide overdose is associated with an approximately 10% mortality rate. The drug’s slow rate of elimination and high oral bioavailability make successful management extremely challenging. I present the management of a life-threatening flecainide overdose of an infant who had a protracted course due to the exposure to the drug in both the fetal and neonatal periods.
Aspects of Cognitive Impairment Associated with Agitated Behaviour during Post-traumatic Amnesia

Published: May 2021

AbstractObjectives:Post-traumatic amnesia (PTA) is a transient period of recovery following traumatic brain injury (TBI) characterised by disorientation, amnesia, and cognitive disturbance. Agitation is common during PTA and presents as a barrier to patient outcome. A relationship between cognitive impairment and agitation has been observed. This prospective study aimed to examine the different aspects of cognition associated with agitation.Methods:The sample comprised 82 participants (75.61% male) admitted to an inpatient rehabilitation hospital in PTA. All patients had sustained moderate to extremely severe brain injury as assessed using the Westmead Post-Traumatic Amnesia Scale (WPTAS) (mean duration = 42.30 days, SD = 35.10). Participants were assessed daily using the Agitated Behaviour Scale and WPTAS as part of routine clinical practice during PTA. The Confusion Assessment Protocol was administered two to three times per week until passed criterion was achieved (mean number assessments = 3.13, SD = 3.76). Multilevel mixed modelling was used to investigate the association between aspects of cognition and agitation using performance on items of mental control, orientation, memory free recall, memory recognition, vigilance, and auditory comprehension.Results:Findings showed that improvement in orientation was significantly associated with lower agitation levels. A nonsignificant trend was observed between improved recognition memory and lower agitation.Conclusions:Current findings suggest that the presence of disorientation in PTA may interfere with a patient’s ability to understand and engage with the environment, which in turn results in agitated behaviours. Interventions aimed at maximizing orientation may serve to minimize agitation during PTA.
A Royal Romance: The Cult of Cyrus the Great in Modern Iran
Authors: ANSARI ALI 
Published: May 2021

Abstract
This article looks at the continuing fascination with the idea of monarchy in Iran, dismissed and condemned after the revolution but gradually rehabilitated through an engagement with the Shahnameh and a reinvigorated interest in ancient Iran. The interest in Sasanian Iran, as the cradle for the development of Islamic civilisation, has in turn enabled a popular re-acquaintance with Achaemenid Iran, previously frowned on for its association with Mohammad Reza Shah but legitimised by the enthusiastic endorsement of the figure of Cyrus the Great by President Ahmadinejad. This political myth of Cyrus the Great reflects the changing political dynamics of the Islamic Republic and the need to appropriate popular nationalist iconography to the state.
India and the pandemic: democratic governance at crossroads
Authors: Ghosh Sujay 
Published: May 2021

AbstractCovid-19 seems to have unlocked the reality of democracy's ongoing tension in many parts of the world, including India. The present government, led by Hindu nationalist Bharatiya Janata Party, enjoys absolute majority in the lower House of Samshad (Indian Parliament); thus satisfies WHO requirement of strong political leadership for meeting the challenge of Covid-19 pandemic. Through analysis of various acts, rules, notifications, social media behaviour, media-representations and reports, two aspects of governance become relevant: the process of policy-communication on the pandemic, particularly while declaring and extending lockdowns, through widely publicised speeches of the Prime Minister, packed with emotive appeals and policy-propaganda. However, government's several omissions and commissions have defied the norms of democratic accountability. In response, opposition political parties and civil society activism have continuously contested these trends, for stretching the democratic space wider and achieving better governance outcomes.
The Same Yesterday and Today and Forever? A Hermeneutical Study of the Use of the Old Testament in the Epistle to the Hebrews and its Implications for Scriptural Authority and Biblical Preaching in a Secularized Western Setting
Authors: Maginnis Samuel 
Published: May 2021

AbstractSecularization and pluralism have created a crisis of biblical authority within contemporary Western Christianity. Responding to this, Christine McSpadden has produced a manifesto for preachers which approaches the Bible not as just one ‘sacred text’ amongst others but as a unique means of life-changing encounter with the living and active Word of God. Though she makes no reference to it, McSpadden’s understanding of Scripture closely echoes that of one of the earliest Christian texts, the Epistle to the Hebrews. The purpose of this paper is to examine Hebrews’ use of the Old Testament and what its interpretive method reveals about the author’s understanding of the nature of Scripture; to identify the extent to which McSpadden’s approach follows this understanding and method; and to determine what further implications this shared tradition may have for the doctrine of scriptural authority and the practice of biblical preaching in a contemporary Western setting. It concludes that McSpadden’s approach stands firmly in the tradition first articulated in Hebrews and that together they reflect the most ancient Christian understanding of scriptural authority, which protects the Bible texts from historical irrelevance on one hand and from unduly speculative and subjective interpretations on the other.

AbstractThis study focuses on the accuracy of longwave radiation flux retrievals at the top and bottom of the atmosphere at Eureka station, Canada, in the high Arctic. We report comparisons between seven products derived from (a) calculations based on a combination of ground‐based and space‐based lidar and radar observations, (b) standard radiometric observations from the CERES sensor, (c) direct observations at the surface from a broadband radiation station, and (d) the ERA‐Interim and ERA5 reanalyzes. Statistical, independent analyses are first performed to look at recurring bias and trends in fluxes at Top and Bottom of the Atmosphere (TOA, BOA). The analysis is further refined by comparing fluxes derived from coincident observations decomposed by scene types. Results show that radiative transfer calculations using ground‐based lidar‐radar profiles derived at Eureka agree well with TOA LW fluxes observed by CERES and with BOA LW fluxes reference. CloudSat‐CALIPSO also shows good agreement with calculations from ground‐based sensor observations, with a relatively small bias. This bias is shown to be largely due to low and thick cloud occurrences that the satellites are insensitive to owing to attenuation from clouds above and surface clutter. These conditions of opaque low clouds, cause an even more pronounced bias for CERES BOA flux calculation in winter, due to the deficit of low clouds identified by MODIS. ERA‐I and ERA5 fluxes behave differently, the large positive bias observed with ERA‐I is much reduced in ERA5. ERA5 is closer to reference observations due to better behavior of low and mid‐level clouds and surface temperature.

AbstractThe energetic particle precipitation (EPP) indirect effect (IE) refers to the downward transport of reactive odd nitrogen (NOx = NO + NO2) produced by EPP (EPP‐NOx) from the polar winter mesosphere and lower thermosphere to the stratosphere where it can destroy ozone. Previous studies of the EPP IE examined NOx descent averaged over the polar region, but the work presented here considers longitudinal variations. We report that the January 2009 split Arctic vortex in the stratosphere left an imprint on the distribution of NO near the mesopause, and that the magnitude of EPP‐NOx descent in the upper mesosphere depends strongly on the planetary wave (PW) phase. We focus on an 11‐day case study in late January immediately following the 2009 sudden stratospheric warming during which regional‐scale Lagrangian coherent structures (LCSs) formed atop the strengthening mesospheric vortex. The LCSs emerged over the north Atlantic in the vicinity of the trough of a 10‐day westward traveling planetary wave. Over the next week, the LCSs acted to confine NO‐rich air to polar latitudes, effectively prolonging its lifetime as it descended into the top of the polar vortex. Both a whole atmosphere data assimilation model and satellite observations show that the PW trough remained coincident in space and time with the NO‐rich air as both migrated westward over the Canadian Arctic. Estimates of descent rates indicate five times stronger descent inside the PW trough compared to other longitudes. This case serves to set the stage for future climatological analysis of NO transport via LCSs.
The Impact of Southern Ocean Ekman Pumping, Heat and Freshwater Flux Variability on Intermediate and Mode Water Export in CMIP Models: Present and Future Scenarios
Authors: Almeida Lucas , Mazloff Matthew R. , Mata Mauricio M. 
Published: May 2021

AbstractSubduction in the Antarctic circumpolar region of the Southern Ocean (SO) results in the formation of Antarctic Intermediate Water (AAIW) and Subantarctic Mode Water (SAMW). Theoretical understanding predicts that subduction rates of these waters masses is driven by wind stress curl and buoyancy fluxes. The objective of this work is to evaluate the extent to which AAIW and SAMW variability are correlated to SO air‐sea fluxes and how potential changes to those forcings would impact the future water mass export rates. We correlate the water mass volume transport at 30°S with Ekman pumping, freshwater and heat fluxes in the Coupled Model Intercomparison Project. The export of these water masses varies across models, with most overestimating the total transport. Correlation coefficients between the air‐sea fluxes and exports are consistent with theoretical expectations. In the picontrol/historical scenarios, the highest correlations with AAIW export variability are heat flux, while Ekman pumping best explains SAMW. However, multivariate regressions show that both AAIW and SAMW export variability are better explained using the combination of all three fluxes. In future scenario simulations air‐sea fluxes trend significantly in the catastrophic scenario (RCP8.5 and SSP8.5). Both AAIW and SAMW are still highly correlated to the fluxes, but with different correlation coefficients. The dominant forcing components even change from the present simulations to the future scenario runs. Thus, correlations between AAIW and SAMW transports and air‐sea fluxes are not stationary in time, limiting the predictive skill of statistical models and highlighting the importance of using complex climate models.

AbstractSeveral psychiatric, neurologic and neurodegenerative disorders present increased brain ventricles volume, being hydrocephalus the disease with the major manifestation of ventriculomegaly caused by the accumulation of high amounts of cerebrospinal fluid (CSF). The molecules and pathomechanisms underlying cerebral ventricular enlargement are widely unknown. Kinase D interacting substrate of 220 kDa (KIDINS220) gene has been recently associated with schizophrenia and with a novel syndrome characterized by spastic paraplegia, intellectual disability, nystagmus and obesity (SINO syndrome), diseases frequently occurring with ventriculomegaly. Here we show that Kidins220, a transmembrane protein effector of various key neuronal signalling pathways, is a critical regulator of CSF homeostasis. We observe that both KIDINS220 and the water channel aquaporin-4 (AQP4) are markedly downregulated at the ventricular ependymal lining of idiopathic normal pressure hydrocephalus (iNPH) patients. We also find that Kidins220 deficient mice develop ventriculomegaly accompanied by water dyshomeostasis and loss of AQP4 in the brain ventricular ependymal layer and astrocytes. Kidins220 is a known cargo of the SNX27-retromer, a complex that redirects endocytosed plasma membrane proteins (cargos) back to the cell surface, thus avoiding their targeting to lysosomes for degradation. Mechanistically, we show that AQP4 is a novel cargo of the SNX27-retromer and that Kidins220 deficiency promotes a striking and unexpected downregulation of the SNX27-retromer that results in AQP4 lysosomal degradation. Accordingly, SNX27 silencing decreases AQP4 levels in wild-type astrocytes whereas SNX27 overexpression restores AQP4 content in Kidins220 deficient astrocytes. Together our data suggest that the KIDINS220-SNX27-retromer-AQP4 pathway is involved in human ventriculomegaly and open novel therapeutic perspectives.

AbstractOxysterol-binding protein-like 2 (OSBPL2), also known as oxysterol-binding protein-related protein (ORP) 2, is a member of lipid transfer protein well-known for its role in regulating cholesterol homeostasis. A recent study reported that OSBPL2/ORP2 localizes to lipid droplets (LDs) and is associated with energy metabolism and obesity. However, the function of OSBPL2/ORP2 in adipocyte differentiation is poorly understood. Here, we report that OSBPL2/ORP2 contributes to the developmental progression of preadipocytes. We found that OSBPL2/ORP2 binds to β-catenin, a key effector in the Wnt signaling pathway that inhibits adipogenesis. This complex plays a role in regulating the protein level of β-catenin only in preadipocytes, not in mature adipocytes. Our data further indicated that OSBPL2/ORP2 mediates the transport of β-catenin into the nucleus and thus regulates target genes related to adipocyte differentiation. Deletion of OSBPL2/ORP2 markedly reduces β-catenin both in the cytoplasm and in the nucleus, promotes preadipocytes maturation, and ultimately leads to obesity-related characteristics. Altogether, we provide novel insight into the function of OSBPL2/ORP2 in the developmental progression of preadipocytes and suggest OSBPL2/ORP2 may be a potential therapeutic target for the treatment of obesity-related diseases.

AbstractThe aim of the present study was to describe the genetic structure of the Norwegian population using genotypes from 6369 unrelated individuals with detailed information about places of residence. Using standard single marker- and haplotype-based approaches, we report evidence of two regions with distinctive patterns of genetic variation, one in the far northeast, and another in the south of Norway, as indicated by fixation indices, haplotype sharing, homozygosity, and effective population size. We detect and quantify a component of Uralic Sami ancestry that is enriched in the North. On a finer scale, we find that rates of migration have been affected by topography like mountain ridges. In the broader Scandinavian context, we detect elevated relatedness between the mid- and northern border areas towards Sweden. The main finding of this study is that despite Norway’s long maritime history and as a former Danish territory, the region closest to mainland Europe in the south appears to have been an isolated region in Norway, highlighting the open sea as a barrier to gene flow into Norway.

AbstractHard disk drives (HDDs) are used as secondary storage in digital electronic devices owing to low cost and large data storage capacity. Due to the exponentially increasing amount of data, there is a need to increase areal storage densities beyond ~1 Tb/in2. This requires the thickness of carbon overcoats (COCs) to be <2 nm. However, friction, wear, corrosion, and thermal stability are critical concerns below 2 nm, limiting current technology, and restricting COC integration with heat assisted magnetic recording technology (HAMR). Here we show that graphene-based overcoats can overcome all these limitations, and achieve two-fold reduction in friction and provide better corrosion and wear resistance than state-of-the-art COCs, while withstanding HAMR conditions. Thus, we expect that graphene overcoats may enable the development of 4–10 Tb/in2 areal density HDDs when employing suitable recording technologies, such as HAMR and HAMR+bit patterned media
