Site Characterization at Downhole Arrays by Joint Inversion of Dispersion Data and Acceleration Time Series
Authors: Seylabi Elnaz , Stuart Andrew M. , Asimaki Domniki 
Published: May 2020

ABSTRACTWe present a sequential data assimilation algorithm based on the ensemble Kalman inversion to estimate the near-surface shear-wave velocity profile and damping; this is applicable when heterogeneous data and a priori information that can be represented in forms of (physical) equality and inequality constraints in the inverse problem are available. Although noninvasive methods, such as surface-wave testing, are efficient and cost-effective methods for inferring an VS profile, one should acknowledge that site characterization using inverse analyses can yield erroneous results associated with the lack of inverse problem uniqueness. One viable solution to alleviate the unsuitability of the inverse problem is to enrich the prior knowledge and/or the data space with complementary observations. In the case of noninvasive methods, the pertinent data are the dispersion curve of surface waves, typically resolved by means of active source methods at high frequencies and passive methods at low frequencies. To improve the inverse problem suitability, horizontal-to-vertical spectral ratio data are commonly used jointly with the dispersion data in the inversion. In this article, we show that the joint inversion of dispersion and strong-motion downhole array data can also reduce the margins of uncertainty in the VS profile estimation. This is because acceleration time series recorded at downhole arrays include both body and surface waves and therefore can enrich the observational data space in the inverse problem setting. We also show how the proposed algorithm can be modified to systematically incorporate physical constraints that further enhance its suitability. We use both synthetic and real data to examine the performance of the proposed framework in estimation of the VS profile and damping at the Garner Valley downhole array and compare them against the VS estimations in previous studies.
Multimodal metaphors: from language as a condition to text to the notion of texture as a meaning-making semiotic resource

Published: May 2020

Abstract: In this paper, we attempt to provide some ways of thinking about text, relating it to the concept of metaphors, multimodality and texture. Our aim is to develop new insights in meaning making and communication more generally, by bringing examples of memes; a relatively new genre, often seen on social media posts. To do so, we discuss the notion of text (HALLIDAY; HASAN, 2002; BEAUGRANDE, 1997; KRESS, 2010) and then, we discuss texture as a semiotic resource for the production of texts and its metaphors (DJONOV; VAN LEEUWEN, 2011). To exemplify some concepts and categories, we explore memes, seeking to understand their constitution as well as their qualities and potential meanings of visual textures deployed in the text to make meaning material through multimodal metaphors.Keywords: text; texture; social semiotics; multimodal metaphors.Resumo: Neste artigo, pretendemos propor algumas maneiras para se pensar a noção de texto, relacionando-a aos conceitos de metáfora, multimodalidade e textura. Nosso objetivo é desenvolver novos insights a respeito da produção de sentido e da comunicação de forma geral. Como exemplo, trazemos memes com o bordão “É verdade esse bilete”. Como esse gênero é relativamente novo e frequentemente visto em posts nas redes sociais, discutimos a noção de texto (HALLIDAY; HASAN, 2002; BEAUGRANDE, 1997; KRESS, 2010) e de textura como um recurso semiótico para a produção de textos e suas metáforas (DJONOV; VAN LEEUWEN, 2011). Para exemplificar algumas noções e categorias, exploramos os memes, buscando compreender como eles se constituem, assim como suas qualidades e seus possíveis sentidos de texturas visuais utilizadas para produção de metáforas multimodais.Palavras-chave: texto; textura; semiótica social; metáforas multimodais.

Published: May 2020

Background: A few studies have been conducted to explore the association of MTHFR A1298C (rs1801131) polymorphism with preterm birth risk, the results remain inconsistent. Therefore, we conducted a meta-analysis to derive a more systematic estimation of the association.

Method: Relevant studies were searched by PubMed, EMBASE, CNKI, and Google Scholar up to June 2018. The strength of the association of MTHFR A1298C polymorphism with preterm birth was calculated by odds ratios (OR) with 95% confidence interval (95%CI).

Results: A total of nine case-control studies with 1,609 cases and 14,981 controls were included. Pooled results showed that there was no significant association between MTHFR A1298C polymorphism and preterm birth risk under all five genetic models in overall. However, in the stratified analysis of ethnicity, a significant association between MTHFR A1298C polymorphism and preterm birth risk was observed in the Asians under four genetic models, i.e., allele (C vs. A: OR = 0.960, 95% CI 0.543-0.871, P = 0.002), heterozygote (CA vs. AA: OR = 0.887, 95% CI 0.024-0.457, P = 0.003), dominant (CC+CA vs. AA: OR = 0.965, 95% CI 0.534 -0.935, P = 0.015) and recessive (CC vs. CA+AA: OR = 0.923, 95% CI 0.026-0491, P = 0.004), but not in Caucasians.

Conclusion: This meta-analysis suggested that MTHFR A1298C polymorphism is not associated with preterm birth risk in overall population. However, MTHFR A1298C polymorphism plays an important role in preterm birth development in Asian population.

Published: May 2020

La infección con toxoplasma gondii durante el embarazo produce compromiso fetal en 9 a 27% de los casos cuando la gestante se infecta durante el primero o segundo trimestres y 59% si ocurre durante el tercer trimestre. La infección fetal produce serias consecuencias. El diagnóstico de infección congénita se ha sustentado mediante estudios inmunológicos, los cuales son de difícil interpretación. Esta publicación describe nuestra experiencia con la Reacción en Cadena de la Polimerasa (PCR) en líquido amniótico como predictor de compromiso fetal en gestantes con evidencia inmunológica de infección activa. Entre julio de 1996 y septiembre de 2000 se han evaluado 534 muestras de líquido amniótico, encontrándose una frecuencia de casos positivos del 7.1%. La frecuencia según edad gestacional fue 6.5% (12-15 s);16.1% (16-19 s); 20% (20-23 s); 21.5% (24-27s); 17.6% (28-31 s); 12.7% (32-35s); 1.7% (36-39 s). De los 38 casos positivos 20 son clínicamente normales, uno presenta problemas visuales y otro, leve retardo en el desarrollo psicomotor. De los 16 casos restantes, se presentaron 4 muertes fetales, 11 no han podido ser seguidos y 1 no ha nacido aún. La PCR es una metodología sensible y específica para confirmar infección fetal, y permite tomar medidas terapéuticas aún desde el periodo gestacional mejorando el pronóstico de los infantes infectados.

Objetivo: Explorar la asociación entre las inmunoglobulinas G anticardiolipina (AC) y anti b2 glicoproteína I (Ab2GP I) con preeclampsia (PE) y sus complicaciones antes de las 35 semanas de gestación.Metodología: Estudio prosprectivo descriptivo de casos (55 preeclámpticas) y controles (55 gestantes no preeclámpticas) con menos de 35 semanas de gestación, de los Hospitales Universitario San Vicente de Paúl y General de Medellín, entre 1° de septiembre de 1999 y 1° de septiembre 2000.Resultados: El análisis de las variables sobre las características generales de los casos y controles no reveló diferencias significativas. Un caso (1,8%) resultó positivo para Ab2GP I vs 5/54 controles (9.2%) (P=0.09 ns). Se presentaron 7/55 casos positivos para AC(12.7%) (interpretada según recomendación de la casa fabricante) vs 11/54 controles (20.3%)(P=0.47 ns). Cuando se interpretó el resultado de AC siguiendo la recomendación internacional (AC1), se encontraron 24/55 casos positivos (43,6%) vs 30/54 controles (55.5%)(P=0.48 ns). En cuanto a las complicaciones, se presentaron 25 casos de RCIU (45.4%) sin asociación con Ab2GP I ni con AC interpretada por cualquiera de los dos métodos. Catorce casos (25.6%) tuvieron otras complicaciones atribuíbles a la PE (HELLP, abrupcio, edema pulmonar, etc.) sin asociación con los anticuerpos estudiados. Ninguno de los controles presentó preeclampsia y sólo uno de los positivos se complicó con tromboembolismo pulmonar pero se demostró estenosis mitral asociada.Conclusión: No hay asociación entre la preeclampsia que se inicia antes de las 35 semanas y sus complicaciones con Ab2GP I ni con AC.

The aim of this research was to describe the psychosocial traits of preschool teachers and to investigate the correlations between these traits. Designed according to the relational screening method, participants in this research comprised 102 teachers working in independent preschools and preschool classes linked to primary schools in Canakkale province. To collect psychosocial data, the research used a personal information form, semi-structured interview form, the Empathic Tendency Scale, Ways of Coping Questionnaire, Satisfaction with Life Scale, Burnout Measuresâ€“ Short Form and Self-Efficacy Scale. Findings obtained in the research showed that having a model (teacher, friend and family) was more effective than other factors in preschool teachers choosing this profession. Nearly, half of the teachers (49%) stated they would choose preschool teaching again if they had the chance, while the remaining teachers stated they would choose a different area of teaching or a different profession (theology, engineering, medicine, etc.).
Keywords: Preschool teachers, psychosocial, life satisfaction, burnout, coping with stress.
Collaborative reflection on shared journal writing to foster EFL teacher CPD
Authors: Elhussain Summaya W. , Khoja Aisha Y. 
Published: May 2020

Despite the importance of Continuous Professional Development in the EFL context, a limited research has been done on EFL teachersâ€™ collaborative reflection on teaching. This study aims to investigate the effectiveness of teachersâ€™ reflection that is fostered and enhanced by the collaborative written exploration of practice using an online-shared teacher journal in a Saudi tertiary context. To achieve this, the study adopted three theoretical foundations: the characteristics of the online teacher professional development, Vygotskyâ€™s zone of proximal development and the constructivist theory of learning. The level of reflection in the teachersâ€™ journal is analysed by using the discourse semantics approach, namely, systemic functional linguistics. Besides, a semi-structured interview is used to collect the qualitative data. They strongly suggest that maintaining an online-shared teachersâ€™ journal will support and augment teachersâ€™ reflection, enhance knowledge and improve teaching performance.
Keywords: Continuous professional development, reflective practice.

Authors: Coskun Zeynep Nesrin , Mitrani Cagla 
Published: May 2020

The aim of the study is to design an effective instruction build on the Dick and Carey Model and game-based learning that enables an undiagnosed language learner of dyslexia, facing problems in vocabulary acquisition to acquire a pre-defined number of vocabularies in a given time. The method of the curriculum development study is based on a case study in a real-life context with quantitative and qualitative evidence that relies on multiple data collection tools such as checklist, interviews, questionnaire and report cards of the learner. The results of the study demonstrated that the capability of the dyslexic learner can be increased to acquire 55 vocabularies in a week, the same number expected from their peers. The performance increase of the learner can be attributed to a new method of learning English vocabulary through game-based learning supported with spaced repetition.

Published: May 2020

Background-Shortages of personal protective equipment (PPE) including N95 filtering facepiece respirators is an urgent concern in the setting of the global COVID-19 pandemic. Decontamination of PPE could be useful to maintain adequate supplies, but there is uncertainty regarding the efficacy of decontamination technologies.Methods-A modification of the American Society for Testing and Materials standard quantitative carrier disk test method (ASTM E-2197-11) was used to examine the effectiveness of ultraviolet-C (UV-C) light, a high-level disinfection cabinet that generates aerosolized peracetic acid and hydrogen peroxide, and dry heat at 70°C for 30 minutes for decontamination of bacteriophages Phi6 and MS2 and methicillin-resistant Staphylococcus aureus (MRSA) inoculated onto 3 commercial N95 respirators. Three and 6 log10 reductions on N95 respirators were considered effective for decontamination and disinfection, respectively. Results-UV-C administered as a 1-minute cycle in a UV-C box or a 30-minute cycle by a room decontamination device reduced contamination but did not meet criteria for decontamination of the viruses from all sites for any of the N95s. The high-level disinfection cabinet was effective for decontamination of all the organisms from the N95s and achieved disinfection with 3 disinfection cycles over ~60 minutes. Dry heat at 70°C for 30 minutes was not effective for decontamination of the bacteriophages. Conclusions-UV-C could be useful to reduce contamination on N95 respirators. However, the UV-C technologies studied did not meet our criteria for decontamination under the test conditions used. The high-level disinfection cabinet was effective for decontamination of N95s and met criteria for disinfection with multiple cycles.
