Effects of hydroxycinnamic acid esters on sweetpotato weevil feeding and oviposition and interactions with Bacillus thuringiensis proteins

Published: November 2020

Sweetpotato weevil (SPW) pest management is challenging because the pest target is sub-terranean, so the application of pesticides is impractical and usually ineffective. Host plant resistance and the genetic transformation of sweetpotatoes to produce entomotoxic Bt proteins offer potential for environmentally benign pest control. Resistance can be conferred by naturally occurring hydroxycinnamic acids which protect against oviposition by adults, but these compounds are restricted to the root surface so do not protect against the cortex bound larvae where the greatest damage occurs. Resistance could be enhanced if combined with expression of Bt proteins in transformed plants, but interactions between hydroxycinnamic acids and Bt proteins remain unknown. Here the bioactivity of Cry7Aa1 protein and hydroxycinnamic acid esters was evaluated individually and in combination against SPW larvae and mortality determined. Low and high concentrations of hydroxycinnamic acid esters alone caused significantly higher mortality of both weevil species in all experiments compared to the control. SPW larval mortality was greater when tested as a combination of hydroxycinnamic acid esters and Bt protein, but this effect was additive not synergistic. Although we report no evidence of antagonistic interactions, the antifeedant effects of the plant compounds conferring host plant resistance could have reduced consumption of the Bt protein in our assays leading to a lower efficacy when combined. Further work is required to determine whether the toxic effects of Bt proteins function alongside host plant resistance in sweetpotato under field conditions.
The impact of wearable cardioverter-defibrillator use on long-term decision for implantation of a cardioverter-defibrillator in a semirural acute care hospital
Authors: Sinha Anil-Martin , Bense Jens , Hohenforst-Schmidt Wolfgang
Published: November 2020

Purpose

Large-scale multi-center studies have reported on efficacy of the wearable cardioverter-defibrillator (WCD). However, outcomes focused on WCD patients treated at community-based acute care centers are lacking.

Methods

Patients with cardiomyopathy were included when left ventricular ejection fraction (LVEF) at baseline was ≤ 35%. There were 120 patients meeting the criteria who also had LVEF measured at baseline and after 90 days of WCD use.

Results

After 90 days of WCD use, there were 44 (37%) patients in whom LVEF improved to > 35%. Comparison of patients, by whether LVEF improved or not, indicated that median days of WCD wear and hours of daily use were similar as well as characteristics, such as gender, age, and starting LVEF; and diagnoses leading to WCD prescription were similar between groups as were symptom-based prescription of medications. At the end of WCD use, improved LVEF > 35% correlated with fewer implantable cardioverter-defibrillator (ICD) implants. There were 4 (3%) episodes of new atrial fibrillation detected during WCD use. The WCD appropriately delivered a shock to 3 (2.5%) patients with VT/VF being terminated by the first shock. All shocked patients survived for at least 24 h post-shock.

Conclusions

During WCD use, ischemic and non-ischemic cardiomyopathy patients manifest improved LVEF by 90 days. Long-term care decisions, such as implantation of an ICD, were influenced by LVEF improvement and occurrence of spontaneous VT/VF. The WCD protected patients from sudden cardiac death (SCD) until patient response to guideline-directed medical therapy could be determined.
The dark side(s) of the EU Directive on copyright and related rights in the Digital Single Market
Authors: Ferri Federico
Published: November 2020

The article examines some pivotal aspects of Directive (EU) 2019/790, which is the new legislative act adopted by the European Union to adapt copyright to the evolving digital environment. Indeed, this measure is meant to have considerable implications on the European plane and is supposed to influence, at least in part, also the relations between the EU and third States in the field of copyright. The Directive shall be transposed by mid 2021, but the time is ripe for a first assessment and some reflections. The analysis primarily investigates the relationship between Digital Single Market and EU copyright law and focuses on the most controversial issues of a long-awaited piece of legislation that so far has been widely criticized. In particular, the article explores three new key points: mandatory exceptions and limitations to right holders’ exclusive rights, press publishers’ rights, and platforms’ liability.
Pore structure and its control on reservoir quality in tight sandstones: a case study of the Chang 6 member of the Upper Triassic Yanchang Formation in the Jingbian oilfield in the Ordos Basin, China
Authors: Bai Yubin , Zhao Jingzhou , Zhao Delin , Zhang Hai , Fu Yong
Published: November 2020

This study applied vacuum-impregnated casting thin sections, fluorescence slices, scanning electron microscopy (SEM), pressure-controlled mercury porosimetry (PCP), rate-controlled mercury porosimetry (RCP), X-ray diffraction of clay minerals, overburden pressure, and conventional physical property strategies to determine the microscopic characteristics of the Chang 6 member, a typical tight sandstone reservoir in the Jingbian oilfield in the Ordos Basin, China. We also analyzed the controlling effects of pore structure on reservoir quality and oiliness. The results showed that the pore types of the Chang 6 sandstone reservoir can be divided into four categories: residual intergranular pores, dissolution pores, intercrystalline pores between clay minerals, and microfractures. The pore size of the Chang 6 sandstone reservoir ranged from 20 to 50 μm. We employed PCP and RCP strategies to characterize the pore structure of the Chang 6 reservoir. The pore radius was less than 2 μm, and on average, the throat radius was less than 0.3 μm. The reservoir physical properties were affected by diagenesis, particularly compaction, and the average porosity failure rate was 56.3%. Cementation made the reservoir more compact, dissolution improved the physical properties of the reservoir locally, and fracturing effectively improved the reservoir seepage ability; however, its influence on porosity was limited. The pore structure controlled the quality of the reservoir. The physical properties of the reservoir were closely related to the oil-bearing properties. The lower limits of porosity and permeability of industrial oil flow in the reservoir were 7.5% and 0.15 mD, respectively. These results provide an additional resource for the exploration and development of tight oil in the Ordos Basin.
Correlating Hard-Braking Activity with Crash Occurrences on Interstate Construction Projects in Indiana
Authors: Desai Jairaj , Li Howell , Mathew Jijo K. , Cheng Yi-Ting , Habib Ayman , Bullock Darcy M.
Published: November 2020

The Federal Highway Administration (FHWA) reported between 2016 and 2017, fatal crashes in work zones increased by 3%, while fatal crashes outside of work zones decreased by 1.5%. The FHWA also reported that work zones account for approximately 10% of the nation’s overall congestion and 24% of unexpected interstate delays. This paper reports on a study of 23 construction work zones that covered approximately 150 centerline miles of Indiana interstate roadway in the summer of 2019. Approximately 50% of all interstate crashes for the period of May to September 2019 occurred within or in an approach upstream or downstream of one of these work zones. Commercially available vehicle hard-braking event data is used for the study and geofenced to the work zone approaches and limits. This research examined 196,215 hard-braking events over a 2-month period in the summer of 2019 and 3132 crashes over the same 2-month period in 2018 and 2019 for the 23 interstate work zones. The study found there were approximately 1 crash/mile for every 147 hard-braking events in and around a construction site. The R2 was approximately 0.85. The paper concludes by recommending that hard-braking event data be used by agencies to quickly identify emerging work zone locations that show relatively large number of hard-braking events for further evaluation.

ABSTRACT

Background:

Coronavirus 2019 (COVID 19) has been reported as a pandemic by the world health organization. Increasing number of cases and associated mortality have demanded the need for clinical studies and researches.

Objective:

The aim of this study is to evaluate intubation prognosis of the COVID 19 patients referred to Shahid Beheshti hospital in Qom city.

Method:

COVID 19 patients referred to (XXX)were included in this study. Clinical sign and symptoms were recorded for each patient in a questionnaire. The diagnosis was made using real time polymerase chain reaction and chest CT scans. Lab findings from renal and liver function tests, blood count, c-reactive protein and electrolytes were also recorded. Shortness of breath was measured using oxygen saturation levels in these patients. The data was recorded in the electronic form and was analyzed using SPSS v21.

Result:

Of 317 patients included in this study, the average age of COVID 19 patients were 59.71 ± 16.46 years. The need of ventilation among the patients older than 50 years was significantly higher than younger patients, p = 0.013. Smoking status, gender and drug addiction was not associated with the need of invasive mechanical ventilation, p = 0.73, p = 0.44 and p = 0.76. Patients need invasive mechanical ventilation compared to those receiving non-invasive ventilation were significantly older, p = 0.001.

Conclusion:

The need of mechanical ventilation is significantly greater in advanced age COVID-19 patients.

Comparison between ketamine and propofol combined against propofol alone for brachial plexus nerve block in open fixation of forearm fracture: A randomized controlled trial
Authors: Moradkhani Mahmoudreza , Shabaninia Shahrzad , Vahabi Sepideh
Published: November 2020

ABSTRACT

Background:

General anesthesia has been successfully replaced by various nervous block for surgeries.

Objective:

The purpose of this study was to examine the combined effect of ketamine and propofol for brachial plexus block.

Method:

In this double-blind randomized trial, 64 patients who underwent open fixation for forearm fracture were randomly assigned to group A (n = 32); comprising of patients who received both propofol (200 mg) and ketamine (50 mg) or group B (n = 32) who received only propofol (200 mg). The infusion was controlled in the groups to induce light-to-moderate sedation. The visual analogue scale (VAS) was used to evaluate pain in the groups. Additionally, parameters such as nausea and vomiting, patients’ satisfaction, blood pressure, heart rate, hallucination and the time of recovery were compared among the groups.

Result:

Due to the failure of nerve block, 7 patients were excluded from the study. A total of 64 patients were equally divided into two groups. Pain, nausea, vomiting, hallucination and patients’ satisfaction were not statistically different among the two groups. Whereas, changes in the blood pressure and heart rate were lesser in Ketamine-propofol group and however, were not reported to be statistically significant.

Conclusion:

Admixture of ketofol, containing a small dose of ketamine, is not an appropriate analgesic adjunct for upper arm nerve block, however, it does not increase the incidence of nausea, vomiting and hallucination.

Published: November 2020

Background

Over the past decade, high submuscular (HSM) placement of inflatable penile prosthesis (IPP) reservoirs has emerged as a viable alternative to space of Retzius (SOR) placement; however, data comparing the feasibility and complications of HSM vs SOR reservoir removal do not presently exist.

Aim

To present a comparison of the safety, feasibility, and ease of removal of HSM vs SOR reservoirs in a tertiary care, university-based, high-volume prosthetic urology practice.

Methods

Data were retrospectively collected on patients who underwent IPP reservoir removal between January 2011 and June 2020. Cases were separated into 2 cohorts based on reservoir location. Statistical analysis was performed using Fisher's exact and Chi-squared tests for categorical variables and Student's t-test for continuous variables. Timing from IPP insertion to explant was compared between the HSM and SOR groups using the Mann-Whitney U test.

Outcomes

Time from IPP insertion to explant, operative time, intraoperative and postoperative complications, and need for a counter incision were compared between the HSM and SOR groups.

Results

Between January 2011 and June 2020, 106 (73 HSM, 33 SOR) patients underwent IPP removal or replacement by a single surgeon at our institution. Average time from IPP insertion to removal was 43.6 months (24.2 HSM, 52.7 SOR, P = .07)—reservoir removal occurred at the time of device explant in 70 of 106 (66%) cases. More HSM reservoirs were explanted at the time of IPP removal compared with the SOR cohort (54 of 73, 74% HSM vs 16 of 33, 48.5% SOR, P = .01). Similar rates of complications were noted between the HSM and SOR groups (1.9% vs 6.3%, P = .35). There was no significant difference in need for counter incision between the 2 groups (24 [42%] HSM vs 4 [25%] SOR, P = .16) or in average operative times (76.5 ± 38.3 minutes HSM vs 68.1 ± 34.3 minutes SOR, P = .52).

Clinical Implications

Our experience with explanting HSM reservoirs supports the safety and ease of their removal.

Strengths and Limitations

Although the absolute cohort size is relatively low, this study reflects one of the largest single-institution experiences examining penile implant reservoir removal. In addition, reservoir location was not randomized but was instead determined by which patients presented with complications necessitating reservoir removal during the study period.

Conclusions

HSM reservoir removal has comparable perioperative complication rates and operative times when compared with SOR reservoir removal.
Narratives of Domestic Violence
Authors: Andrus Jennifer
Published: November 2020

Domestic violence is an intractable social problem that must be understood in order to be eradicated. Using theories of indexicality, identity, and narrative, Andrus presents data from interviews she conducted with victims and law enforcement, and analyses the narratives of their interactions and the identities that emerge. She gives insight into law enforcement views on violence, and prevalent misconceptions, in order to create resources to improve communication with victim/survivors. She also analyzes the ways in which identity emerges and is performed via narrative constructions of domestic violence and encounters between police and victim/survivors. By giving voice to the victims of domestic violence, this book provides powerful insights into the ways that ideology and commonplace misconceptions impact the social construction of domestic violence. It will be invaluable to students and researchers in discourse analysis, applied linguistics and forensic linguistics.
Exploiting Seismic Waveforms
Authors: Kennett Brian , Fichtner Andreas
Published: November 2020

Exploiting Seismic Waveforms introduces a range of recent developments in seismology including the application of correlation techniques, understanding of multi-scale heterogeneity and the extraction of structure and source information by seismic waveform inversion. It provides a full treatment of correlation methods for seismic noise and event signals, and develops inverse methods for both sources and structure. Higher frequency components of seismograms are frequently neglected, or removed by filtering, but they contain information about seismic structure on scales that cannot be revealed by seismic tomography. Sufficient computational resources are now available for waveform inversion for 3-D structure to be a practical procedure and this book describes suitable algorithms and examples reflecting current best practice. Intended for students and researchers in seismology, this book provides a physical understanding of seismic waveforms and the way that different aspects of the seismic wavefield are revealed by the way that seismic data are handled.
The Great War in History
Authors: Winter Jay , Prost Antoine
Published: November 2020

This revised and updated edition of The Great War in History provides the first survey of historical interpretations of the Great War from 1914 to 2020. It demonstrates how the history of the Great War has now gone global, and how the internet revolution has affected the way we understand the conflict. Jay Winter and Antoine Prost assess not only diplomatic and military studies but also the social and cultural interpretations of the war across academic and popular history, family history, and public history, including at museums, on the stage, on screen, in art, and at sites of memory. They provide a fascinating case study of the practice of history and the first survey of the ways in which the Centenary deepened and deflected both public and professional interpretations of the war. This will be essential reading for scholars and students in history, war studies, European history and international relations.
Variable selection methods for identifying predictor interactions in data with repeatedly measured binary outcomes
Authors: Wolf Bethany J. , Jiang Yunyun , Wilson Sylvia H. , Oates Jim C.
Published: November 2020

Introduction:

Identifying predictors of patient outcomes evaluated over time may require modeling interactions among variables while addressing within-subject correlation. Generalized linear mixed models (GLMMs) and generalized estimating equations (GEEs) address within-subject correlation, but identifying interactions can be difficult if not hypothesizeda priori. We evaluate the performance of several variable selection approaches for clustered binary outcomes to provide guidance for choosing between the methods.

Methods:

We conducted simulations comparing stepwise selection, penalized GLMM, boosted GLMM, and boosted GEE for variable selection considering main effects and two-way interactions in data with repeatedly measured binary outcomes and evaluate a two-stage approach to reduce bias and error in parameter estimates. We compared these approaches in real data applications: hypothermia during surgery and treatment response in lupus nephritis.

Results:

Penalized and boosted approaches recovered correct predictors and interactions more frequently than stepwise selection. Penalized GLMM recovered correct predictors more often than boosting, but included many spurious predictors. Boosted GLMM yielded parsimonious models and identified correct predictors well at large sample and effect sizes, but required excessive computation time. Boosted GEE was computationally efficient and selected relatively parsimonious models, offering a compromise between computation and parsimony. The two-stage approach reduced the bias and error in regression parameters in all approaches.

Conclusion:

Penalized and boosted approaches are effective for variable selection in data with clustered binary outcomes. The two-stage approach reduces bias and error and should be applied regardless of method. We provide guidance for choosing the most appropriate method in real applications.
Uninterruptible Power Supply Improves Precision and External Validity of Telomere Length Measurement via qPCR
Authors: Hastings Waylon J. , Eisenberg Dan T.A. , Shalev Idan
Published: November 2020

Technical challenges associated with telomere length (TL) measurements have prompted concerns regarding their utility as a biomarker of aging. Several factors influence TL assessment via qPCR, the most common measurement method in epidemiological studies, including storage conditions and DNA extraction method. Here, we tested the impact of power supply during the qPCR assay. Momentary fluctuations in power can affect the functioning of high-performance electronics, including real-time thermocyclers. We investigated if mitigating these fluctuations by using an uninterruptible power supply (UPS) influenced TL assessment via qPCR. Samples run with a UPS had significantly lower standard deviation (p < 0.001) and coefficient of variation (p < 0.001) across technical replicates than those run without a UPS. UPS usage also improved exponential amplification efficiency at the replicate, sample, and plate levels. Together these improvements translated to increased performance across metrics of external validity including correlation with age, within-person correlation across tissues, and correlation between parents and offspring.

The Order of Signs: Perspectives on the Relationship between Language and Thought during the First Century of Widespread Sign Language Teaching
Authors: Arnaud Sabine
Published: November 2020

While current debates oppose the cochlear implant's privileging of speech acquisition to teaching sign language, nineteenth-century debates, in contrast, opposed those who saw sign language as a tool for learning to read and write, and those who saw in it an autonomous language for organizing thought itself. Should the order of gestural signs follow written syntax? Or should it have its own coherence, that is, possibly a different syntax and order of enunciation? Starting with these questions, distinct teaching legacies developed, specifying which kinds of signs to use in which context and what role signs were to fulfill. This article focuses on French deaf and hearing teachers whose positions were influential throughout Europe and the United States, moving from Abbé de l'Epée's 1784 method to Rémi Valade's 1854 publication of the first sign language grammar.
Role-based engagement: scale development and validation
Authors: Young Stephen F. , Steelman Lisa A. , Pita Matthew D. , Gallo James
Published: November 2020

The purpose of this paper is to build on personal engagement and role theory to develop a conceptual definition of engagement to different organizational roles (job, organization, supervisor, and coworkers) and create and validate the Role-Based Engagement Scale (RBES). Data were collected from four samples (n = 1,302) of employees, including three from multiple organizations and one from an aircraft manufacturer. Results across three studies consistently support the four dimension structure of the RBES, its internal consistency, convergent, discriminant, and predictive validity based on a series of confirmatory factor analyses. The RBES is a psychometrically sound instrument that measures engagement to job, organization, supervisor, and coworkers. This instrument will provide more targeted information for human resource management (HRM) professionals tasked with developing training methods and processes to improve low-scoring dimensions of engagement, optimizing HRM interventions.

Ancient Egyptian mummified shrews (Mammalia: Eulipotyphla: Soricidae) and mice (Rodentia: Muridae) from the Spanish Mission to Dra Abu el-Naga, and their implications for environmental change in the Nile valley during the past two millennia
Authors: Woodman Neal , Ikram Salima
Published: November 2020

Excavation of Ptolemaic Period (ca. 309–30 BC) strata within Theban Tombs 11, 12, -399-, and UE194A by the Spanish Mission to Dra Abu el-Naga (also known as the Djehuty Project), on the west bank of the Nile River opposite Luxor, Egypt, yielded remains of at least 175 individual small mammals that include four species of shrews (Eulipotypha: Soricidae) and two species of rodents (Rodentia: Muridae). Two of the shrews (Crocidura fulvastra and Crocidura pasha) no longer occur in Egypt, and one species (Crocidura olivieri) is known in the country only from a disjunct population inhabiting the Nile delta and the Fayum. Although deposited in the tombs by humans as part of religious ceremonies, these animals probably derived originally from local wild populations. The coexistence of this diverse array of shrew species as part of the mammal community near Luxor indicates greater availability of moist floodplain habitats than occur there at present. These were probably made possible by a greater flow of the Nile, as indicated by geomorphological and palynological evidence. The mammal fauna recovered by the Spanish Mission provides a unique snapshot of the native Ptolemaic community during this time period, and it permits us to gauge community turnover in the Nile valley of Upper Egypt during the last 2000 years. It also serves as a relevant example for understanding the extinction and extirpation of mammal species as effects of future environmental changes predicted by current climatic models.
Slice collective dynamics, projected emittance deterioration and free electron laser performances detrimental effects
Authors: Dattoli G. , Di Mitri S. , Nguyen F. , Petralia A.
Published: November 2020

Self-amplified spontaneous emission (SASE) free electron laser (FEL) devices have disclosed an unexpected interplay between the laser intensity growth and regions of the electron bunch of the order of the coherence length. They are usually identified with the bunch slice and contribute to the laser dynamics with their own characteristics. The dynamical effects inducing geometrical and phase space misalignment of bunch slice in X-ray operating FELs can be traced back to a plethora of phenomena, both in the Linac accelerating section or inside the beam transport optic magnet. They are responsible for spoiling of the beam projected qualities and, if not corrected properly, induce an increase of the saturation length and a decreasing of the output power. We discuss the inclusion of these effects in models employing scaling formulae.
Is being gender nonconforming distressing? It depends where you live: gender equality across 15 nations predicts how much gender nonconformity is related to self-esteem
Authors: Zentner Marcel , von Aufsess Christian
Published: November 2020

Background

Individuals exhibiting gender nonconforming behaviors experience low self-esteem and a number of other mental health conditions, including elevated suicide risk. Most of the relevant evidence is confined to US studies, however. Adopting a cross-national approach, we examined the pervasiveness of the psychological burden associated with gender nonconformity. Because self-esteem is sensitive to the fulfillment of societal expectations for gender conformity, we reasoned that the relationship between gender conformity and self-esteem ought to decrease as societies become less restrictive in their gender norms.

Methods

To test this proposition, we conducted two studies including 18 national samples from 15 countries varying in gender equality. Participants responded to an online survey that included measures of gender conformity and self-esteem (N = 4486).

Results

Using multilevel analyses and meta-analytic statistics over the samples of both studies, we found that as gender equality increased, the association between gender conformity and self-esteem decreased.

Conclusions

The results suggest that rather than being inherently noxious, gender non-conformity becomes detrimental to self-esteem when it clashes with restrictive gender role norms that are enacted by the macrosocial context. We suggest that previous findings on psychological problems related to gender nonconformity be considered within a broader macrosocial context that may constrain people's freedom to move against gender role norms.
GPS and Galileo Triple-Carrier Ionosphere-Free Combinations for Improved Convergence in Precise Point Positioning
Authors: Basile Francesco , Moore Terry , Hill Chris , McGraw Gary
Published: November 2020

In recent years, global navigation satellite system (GNSS) precise point positioning (PPP) has become a standard positioning technique for many applications with typically favourable open sky conditions, e.g. precision agriculture. Unfortunately, the long convergence (and reconvergence) time of PPP often significantly limits its use in difficult and restricted signal environments typically associated with urban areas. The modernisation of GNSS will positively affect and improve the convergence time of the PPP solutions, thanks to the higher number of satellites in view that broadcast multifrequency measurements. The number and geometry of the available satellites is a key factor that impacts on the convergence time in PPP, while triple-frequency observables have been shown to greatly benefit the fixing of the carrier phase integer ambiguities. On the other hand, many studies have shown that triple-frequency combinations do not usefully contribute to a reduction of the convergence time of float PPP solutions.

This paper proposes novel GPS and Galileo triple-carrier ionosphere-free combinations that aim to enhance the observability of the narrow-lane ambiguities. Tests based on simulated data have shown that these combinations can reduce the convergence time of the float PPP solution by a factor of up to 2·38 with respect to the two-frequency combinations. This approach becomes effective only after the extra wide-lane and wide-lane ambiguities have been fixed. For this reason, a new fixing method based on low-noise pseudo-range combinations corrected by the smoothed ionosphere correction is presented. By exploiting this algorithm, no more than a few minutes are required to fix the WL ambiguities for Galileo, even in cases of severe multipath environments.

Published: November 2020

Typical enteropathogenicEscherichia coli(tEPEC) infection is a major cause of diarrhoea and contributor to mortality in children <5 years old in developing countries. Data were analysed from the Global Enteric Multicenter Study examining children <5 years old seeking care for moderate-to-severe diarrhoea (MSD) in Kenya. Stool specimens were tested for enteric pathogens, including by multiplex polymerase chain reaction for gene targets of tEPEC. Demographic, clinical and anthropometric data were collected at enrolment and ~60-days later; multivariable logistic regressions were constructed. Of 1778 MSD cases enrolled from 2008 to 2012, 135 (7.6%) children tested positive for tEPEC. In a case-to-case comparison among MSD cases, tEPEC was independently associated with presentation at enrolment with a loss of skin turgor (adjusted odds ratio (aOR) 2.08, 95% confidence interval (CI) 1.37–3.17), and convulsions (aOR 2.83, 95% CI 1.12–7.14). At follow-up, infants with tEPEC compared to those without were associated with being underweight (OR 2.2, 95% CI 1.3–3.6) and wasted (OR 2.5, 95% CI 1.3–4.6). Among MSD cases, tEPEC was associated with mortality (aOR 2.85, 95% CI 1.47–5.55). This study suggests that tEPEC contributes to morbidity and mortality in children. Interventions aimed at defining and reducing the burden of tEPEC and its sequelae should be urgently investigated, prioritised and implemented.
Building the Berlin Mosque: An Episode inWeltpolitik
Authors: Terrell Robert Shea
Published: November 2020

The Berlin Mosque was the first permanent place of Muslim worship in Germany. Never a purely local affair, the construction of the Berlin Mosque depended on the legacies of imperialism and the shifting geopolitical contexts of the 1920s. International diplomats and former Wilhelmine and Ottoman agents living and working in Weimar Berlin made sense of the mosque project through categories and ideas forged in the decades before the First World War. They gradually recalibrated their ambitions when confronted, as they were, with radical transformations of the Muslim world, from the dissolution of the Ottoman Empire and the abolition of the caliphate to the emergence of new political leaders from Arabia to Afghanistan. This article demonstrates how the construction and uses of the Berlin Mosque closely followed how diplomats and other actors, both German and non-German, assessed the geopolitical potential of a German–Muslim alliance in the post-Ottoman, post-Wilhelmine moment.
Violence by Other Means: Denunciation and Belonging in Post-Imperial Poland, 1918–1923
Authors: Stauter-Halsted Keely
Published: November 2020

Recent scholarship on post-imperial Eastern Europe has emphasised the continuation of wartime violence in post-war states. Focusing on the early years of the Polish Second Republic, this article considers how the ‘unmixing’ of Eastern European peoples also unfolded in ways not explicitly violent. Specifically, I demonstrate how the sorting of returning refugees on Poland's new frontiers, the culling of personnel from the former imperial civil service and the submission of citizen denunciations helped to disaggregate loyal citizens from hostile foreigners. All of these practices highlight the importance of internal bordering as a process that accompanied the formal drawing of international boundaries in this period.

The coronavirus disease 2019 (COVID-19) pandemic has had a profound impact on medical educational curricula. We aimed to examine the impact of these unprecedented changes on the formal education of paediatric cardiology fellows through a nationwide survey. A REDCap™-based voluntary anonymous survey was sent to all current paediatric cardiology fellows in the United States of America in May, 2020. Of 143 respondents, 121 were categorical fellows, representing over one-fourth of all categorical paediatric cardiology fellows in the United States of America. Nearly all (140/143, 97.9%) respondents utilised online learning during the pandemic, with 134 (93.7%) reporting an increase in use compared to pre-pandemic. The percentage of respondents reporting curriculum supplementation with outside lectures increased from 11.9 to 88.8% during the pandemic. Respondents considered online learning to be “equally or more effective” than in-person lectures in convenience (133/142, 93.7%), improving fellow attendance (132/142, 93.0%), improving non-fellow attendance (126/143, 88.1%), and meeting individual learning needs (101/143, 70.6%). The pandemic positively affected the lecture curriculum of 83 respondents (58.0%), with 35 (24.5%) reporting no change and 25 (17.5%) reporting a negative effect. A positive effect was most noted by those whose programmes utilised supplemental outside lectures (62.2 versus 25.0%, p = 0.004) and those whose lecture frequency did not decrease (65.1 versus 5.9%, p < 0.001). Restrictions imposed by the COVID-19 pandemic have greatly increased utilisation of online learning platforms by medical training programmes. This survey reveals that an online lecture curriculum, despite inherent obstacles, offers advantages that may mitigate some negative consequences of the pandemic on fellowship education.

Objective:

Reading difficulties are one of the most significant challenges for children with neurofibromatosis type 1 (NF1). The aims of this study were to identify and categorize the types of reading impairments experienced by children with NF1 and to establish predictors of poor reading in this population.

Method:

Children aged 7–12 years with NF1 (n = 60) were compared with typically developing children (n = 36). Poor word readers with NF1 were classified according to impairment type (i.e., phonological, surface, mixed), and their reading subskills were compared. A hierarchical multiple regression was conducted to identify predictors of word reading.

Results:

Compared to controls, children with NF1 demonstrated significantly poorer literacy abilities. Of the 49 children with NF1 classified as poor readers, 20 (41%) were classified with phonological dyslexia, 24 (49%) with mixed dyslexia, and 5 (10%) fell outside classification categories. Children with mixed dyslexia displayed the most severe reading impairments. Stronger working memory, better receptive language, and fewer inattentive behaviors predicted better word reading skills.

Conclusions:

The majority of children with NF1 experience deficits in key reading skills which are essential for them to become successful readers. Weaknesses in working memory, receptive language, and attention are associated with reading difficulties in children with NF1.
TRANSNATIONAL INTEREST CONVERGENCE AND GLOBAL KOREA AT THE EDGE OF RACE AND QUEER EXPERIENCES
Authors: Thomsen Patrick S.
Published: November 2020

This is a story about gay/queer globalization unfolded through the narratives of Korean gay men in Seoul. In this paper, I make use of talanoa dialogues to apprehend the way race and racial hierarchies can provide insights into the conditions in which the gay subject in Seoul is intelligible in intercultural interactions. I present these narratives in the format of a thematic talanoa using Pacific Research Methodologies (PRM). In doing so, I advance a unique way to negotiate communication with participants in a cross-cultural setting, rendering myself visible as a racialized (Sāmoan) researcher. Empirically, I argue that the narratives of Korean gay men party to this study demonstrate how the Korea/local–West/global binary is an important referential, in that there exists a structural connection through immigration policies that facilitates a transnational convergence of local and global racial hierarchies. This connection, I also argue, helps to structure and position Whiteness at the apex of racial hierarchies around foreigner subjectivities in South Korea.

A brief review of research findings regarding twins living apart is presented. This review is followed by a look into the lives of a pair of monozygotic male twins who have lived in different continents for many years, but who stay closely connected. The reasons behind their decision and its impact on their behavioral resemblance and social relationship quality are examined. The next section summarizes recent studies that address the management of monochorionic-diamniotic twin pregnancies, paternity testing in multiple pregnancies, trisomies in twin pregnancies and the roots of resilience. The final portion of this article presents human-interest stories involving reunited Brazilian twins, a new resource for twins with disabled co-twins, twins separated in the Secret of the Nile television series, a new book about Dr Josef Mengele and his horrific twin experiments conducted at the Auschwitz–Birkenau concentration camp, and a pair of twins dedicated to helping others.

Previous genetic studies on hair morphology focused on the overall morphology of the hair using data collected by self-report or researcher observation. Here, we present the first genome-wide association study (GWAS) of a micro-level quantitative measure of hair curvature. We compare these results to GWAS results obtained using a macro-level classification of observable hair curvature performed in the same sample of twins and siblings of European descent. Observational data were collected by trained observers, while quantitative data were acquired using an Optical Fibre Diameter Analyser (OFDA). The GWAS for both the observational and quantitative measures of hair curvature resulted in genome-wide significant signals at chromosome 1q21.3 close to the trichohyalin (TCHH) gene, previously shown to harbor variants associated with straight hair morphology in Europeans. All genetic variants reaching genome-wide significance for both GWAS (quantitative measure lead single-nucleotide polymorphism [SNP] rs12130862, p = 9.5 × 10–09; observational measure lead SNP rs11803731, p = 2.1 × 10–17) were in moderate to very high linkage disequilibrium (LD) with each other (minimum r2 = .45), indicating they represent the same genetic locus. Conditional analyses confirmed the presence of only one signal associated with each measure at this locus. Results from the quantitative measures reconfirmed the accuracy of observational measures.
Angststörungen – von der ICD-10 zur ICD-11
Authors: Vloet Timo D. , Romanos Marcel
Published: November 2020

Zusammenfassung. Hintergrund: Nach 12 Jahren Entwicklung wird die 11. Version der International Classification of Diseases (ICD-11) von der Weltgesundheitsorganisation (WHO) im Januar 2022 in Kraft treten. Methodik: Im Rahmen eines selektiven Übersichtsartikels werden die Veränderungen im Hinblick auf die Klassifikation von Angststörungen von der ICD-10 zur ICD-11 zusammenfassend dargestellt. Ergebnis: Die diagnostischen Kriterien der generalisierten Angststörung, Agoraphobie und spezifischen Phobien werden angepasst. Die ICD-11 wird auf Basis einer Lebenszeitachse neu organisiert, sodass die kindesaltersspezifischen Kategorien der ICD-10 aufgelöst werden. Die Trennungsangststörung und der selektive Mutismus werden damit den „regulären“ Angststörungen zugeordnet und können zukünftig auch im Erwachsenenalter diagnostiziert werden. Neu ist ebenso, dass verschiedene Symptomdimensionen der Angst ohne kategoriale Diagnose verschlüsselt werden können. Diskussion: Die Veränderungen im Bereich der Angsterkrankungen umfassen verschiedene Aspekte und sind in der Gesamtschau nicht unerheblich. Positiv zu bewerten ist die Einführung einer Lebenszeitachse und Parallelisierung mit dem Diagnostic and Statistical Manual of Mental Disorders (DSM-5). Schlussfolgerungen: Die entwicklungsbezogene Neuorganisation in der ICD-11 wird auch eine verstärkte längsschnittliche Betrachtung von Angststörungen in der Klinik sowie Forschung zur Folge haben. Damit rückt insbesondere die Präventionsforschung weiter in den Fokus.
Present‐Day Deformation Mechanism of the Northeastern Mina Deflection Revealed by the 2020 Mw 6.5 Monte Cristo Range Earthquake
Authors: Zheng Ao , Chen Xiaofei , Xu Wenbin
Published: November 2020

The 15 May 2020 Monte Cristo Range Mw 6.5 earthquake occurred in the northeast of the Mina deflection, which accommodates approximately a quarter of the relatively dextral motion between the Pacific and North American plates. The Monte Cristo Range event provides an opportunity to study the present‐day regional deformation mechanism and active tectonics. In this study, we investigate the source rupture process of the event using joint inversion of interferometric synthetic aperture radar and broadband seismic data. We find that the rupture propagates almost simultaneously on two main segments. The fault motion changes from the predominantly sinistral slip near the epicenter on the eastern segment to the oblique slip on the western segment, with a maximum coseismic slip of 0.8 m. Our results suggest that the accommodation of slip transfer localized in the northeastern Mina deflection tends to transform from the wrench‐ to extension‐dominated transtension.
