Abstract. With a few exceptions, most studies on tropospheric ozone (O3) variability during and following the COVID-19 economic downturn focused on high-emission regions or urban environments. In this work, we investigated the impact of the societal restriction measures during the COVID-19 pandemic on surface O3 at several high-elevation sites across North America and Western Europe. Monthly O3 anomalies were calculated for 2020 and 2021, with respect to the baseline period 2000–2019, to explore the impact of the economic downturn initiated in 2020 and its recovery in 2021. In total, 41 high-elevation sites were analyzed: 5 rural or mountaintop stations in Western Europe, 19 rural sites in the Western US, 4 sites in the Western US downwind of highly polluted source regions, 4 rural sites in the eastern US, plus 9 mountaintop or high-elevation sites outside Europe and the United States to provide a “global” reference. In 2020, the European high-elevation sites showed persistent negative surface O3 anomalies during spring (March–May, i.e., MAM) and summer (June–August, i.e., JJA), except for April. The pattern was similar in 2021, except for June. The rural sites in the Western US showed similar behavior, with negative anomalies in MAM and JJA 2020 (except for August), and MAM 2021. The JJA 2021 seasonal average was influenced by strong positive anomalies in July, due to large and widespread wildfires across the Western US. The polluted sites in the Western US showed negative O3 anomalies during MAM 2020, and a slight recovery in 2021, resulting in a positive average anomaly for MAM 2021 and a pronounced month-to-month variability in JJA 2021 anomalies. The Eastern US sites were also characterized by below average O3 for both MAM and JJA 2020, while in 2021 the negative values exhibited an opposite structure compared to the Western US sites, which were influenced by wildfires. Concerning the rest of the World, a global picture could not be drawn, as the sites, spanning a range of different environments, did not show consistent anomalies, with a few sites not experiencing any notable variation. Moreover, we also compared our surface anomalies to the variability of mid-tropospheric O3 detected by the IASI satellite instrument. Negative anomalies were observed by IASI, consistent with published satellite and modeling studies, suggesting that the anomalies can be largely attributed to the reduction of O3 precursor emissions in 2020.

Abstract. The illegal burning of solid wastes in residential stoves is an existing practice yet until now it has been completely disregarded as an emission source of atmospheric pollutants in many developed countries including those in Eastern Europe. Various types of solid wastes (plastics, treated wood, plyboards, tyre, rag, etc.) serve as an auxiliary fuel in many households, in particular during the heating season. In this work, for the first time ever in atmospheric pollution studies, specific tracer compounds identified previously in controlled test burnings of different waste types in the laboratory were detected and quantified in ambient PM10 samples collected in 5 Hungarian and 4 Romanian settlements. Using the identified tracers and their experimentally determined relative emission factors the potential contribution of illegal waste burning emissions to ambient PM10 mass concentrations was assessed. Our findings implied that the burning of PET-containing waste (food and beverage packaging, clothes) was predominant at all locations, especially in North-Eastern Hungary and Romania. There is substantial evidence that the burning of scrap furniture is also common in big cities in Hungary and Romania. Back-of-the-envelope calculations based on the relative emission factors of individual tracers suggested that the contribution of solid waste burning particulate emissions to ambient PM10 mass concentrations may be as high as a few percents. This finding, when considering the extreme health hazards associated with particulate emissions from waste burning, is a matter of serious public health concerns.
Impact of faults on the remote stress state
Authors: Reiter Karsten , Heidbach Oliver , Ziegler Moritz
Published: August 2023

Abstract. The impact of faults on the contemporary stress field in the upper crust has been discussed in various studies. Data and models clearly show that there is an impact, but so far, a systematic study that quantifies the impact as a function of distance to the fault is missing. As there is a lack of dense data, we use here a series of generic 3-D-models to investigate which component of the 3-D-stress tensor is affected at what distance to the fault. Our focus is on the far-field beyond hundreds of meters from the fault. The models test different approaches to implement faults, different material properties, different boundary conditions, variable orientation, and size of the fault. The results of our study show that beyond 1.000 m distance to the fault, the displacements along the fault and its strength contrast neither leaves an imprint on the orientation of the stress tensor nor in the magnitude of the principal stresses in the far field. This finding agrees with robust data from either stress magnitude measurements or areas where high-quality and high-resolution data on the change in orientation of the stress tensor are available. The latter shows often continuous and gradual rotation of the stress tensor orientation over lateral spatial scales of 10 km or larger. These rotations cannot be attributed to faults as they only have an impact on scales <1 km down to several meters only, as observed in numerous boreholes. Thus, we postulate that most stress orientation changes that are assigned to faults may have a different source.
Role of mean and variability change in changes in European annual and seasonal extreme precipitation events
Authors: Wood Raul R.
Published: August 2023

Abstract. The frequency of precipitation extremes is set to change
in response to a warming climate. Thereby, the change in
extreme precipitation event occurrence is influenced by both a shift in the mean and a
change in variability. How large the individual contributions are from either of
them (mean or variability) to the change in precipitation extremes is
largely unknown. This is, however, relevant for a better understanding of how
and why climate extremes change. For this study, two sets of forcing
experiments from the regional CRCM5 initial-condition large ensemble are
used: a set of 50 members with historical and RCP8.5 forcing and a
35-member (700-year) ensemble of pre-industrial natural forcing. The concept
of the probability risk ratio is used to partition the change in extreme-event occurrence into contributions from a change in mean climate or a
change in variability. The results show that the contributions from a change
in variability are in parts equally important to changes in the mean and
can even exceed them. The level of contributions shows high spatial
variation, which underlines the importance of regional processes for changes
in extremes. While over Scandinavia or central Europe the mean influences the
increase in extremes more, the increase is driven by changes in
variability over France, the Iberian Peninsula, and the Mediterranean. For
annual extremes, the differences between the ratios of contribution of mean
and variability are smaller, while on seasonal scales the difference in
contributions becomes larger. In winter (DJF) the mean contributes more to
an increase in extreme events, while in summer (JJA) the change in
variability drives the change in extremes. The level of temporal aggregation
(3, 24, 72 h) has only a small influence on annual and winterly extremes,
while in summer the contribution from variability can increase with longer
durations. The level of extremeness for the event definition generally
increases the role of variability. These results highlight the need for a
better understanding of changes in climate variability to better understand
the mechanisms behind changes in climate extremes.
Technical Note: Resolution Enhancement of Flood Inundation Grids

Published: August 2023

Abstract. High-resolution flood maps are needed for more effective flood risk assessment and management. Producing these directly with hydrodynamic models is slow and computationally prohibitive at large scales. Here we demonstrate a new algorithm for post-processing low-resolution inundation layers by using high-resolution terrain models to disaggregate or downscale. The new algorithm is roughly eight times faster than current state-of-the-art algorithms, shows a slight improvement in accuracy when evaluated against observations of a recent flood, and is open source. The algorithm developed here can be applied in conjunction with a low-resolution hydrodynamic model and a high-resolution DEM to rapidly produce high-resolution inundation maps. For example, in our case study with a river reach of 20 km, the proposed algorithm generated a 4 m resolution inundation map from 32 m hydrodynamic model outputs in 33 seconds, compared to a 4 m hydrodynamic model runtime of 34 minutes. This 60-fold improvement in runtime is associated with a 25 % increase in RMSE when compared against the 4 m hydrodynamic model results and observations of a recent flood. Substituting downscaling into flood risk model chains for high-resolution modelling has the potential to drastically improve the efficiency of inundation map production and increase the lead time of impact-based forecasts, helping more at-risk communities prepare for and mitigate flood damages.
Fractal-based numerical simulation of multivariate typhoon wind speeds utilizing Weierstrass Mandelbrot function

Published: August 2023

Abstract. This paper proposes a fractal-based technique for simulating multivariate nonstationary wind speed fields by the stochastic Weierstrass Mandelbrot function. Upon conducting a systematic fractal analysis, it was found that the structure function method is more suitable and reliable than the box counting method, variation method, and R/S analysis method for estimating the fractal dimension of the stochastic wind speed series. Wind field measurement at the meteorological gradient tower with a height of 356 m in Shenzhen was conducted during Typhoon Mangkhut (2018). Significant non-stationary properties and fractal dimensions of typhoon wind speed data at various heights were analyzed and used to demonstrate the effectiveness of the proposed multivariate typhoon wind speed simulation method. The multivariate wind speed components simulated by the proposed fractal-based method are in good agreement with the measured records in terms of the fractal dimension, standard deviation, probability density function, wind spectrum and cross-correlation coefficient.

Published: August 2023

Lung abscess is a microbial infection that can cause necrosis of the lung tissue and formation of cavities. Antibiotics and bronchoscopy are needed in the management of large lung abscess to prevent further complications. However, some of the cases have poor clinical improvement. The aim of this case report was to describe a patient with large lung abscess who had well responded to antibiotic therapy combined with bronchoscopy drainage. We reported a 55-year-old man with a lung abscess presented with initial symptom of acute productive cough for two weeks. Chest computed tomography (CT) scan with contrast of patient indicated a massive abscess on the right lung segment with a size of 10.9 x 10.41 x 8 cm. Laboratory examination showed leukocytosis. Bronchoscopy was performed as a diagnostic and therapeutic procedure. Antibiotic resistance test was conducted from bronchoalveolar lavage sample to determine the most suitable antibiotics for the patient. The culture yielded a positive for Klebsiella oxytoca that was resistant to ampicillin and cefazolin. The bacterium was sensitive to piperacillin-tazobactam, aztreonam, ceftazidime, ceftriaxone, ertapenem, cefepime, nitrofurantoin, meropenem, amikacin, gentamicin, ciprofloxacin, tigecycline, trimethoprim- sulfamethoxazole, and levofloxacin. Levofloxacin 750 mg injection was given for 14 days followed with oral levofloxacin 500 mg once a day for four weeks and bronchoscopy to stop the microbial infection process in the lung tissues. Lung abscess reduced significantly and the patient was followed until recovered. In conclusion, early combination therapy of adequate antibiotics and bronchoscopy is effective in treating a massive lung abscess caused by Klebsiella oxytoca.

Isolated Cascaded DAB DC-DC Converter to Boost Medium DC Voltage to HVDC
Authors: Afridi Muhammad Danial
Published: August 2023

The offshore wind farms typically use ac system to collect power from each generator, with the voltage increased by means of high, heavy step-up transformers. DC collection grids have also recently been taken into consideration as solution to simplify and minimize the offshore windfarm platforms. DC collection grids offer an additional method to reduce complexity of offshore windfarms. However, to increase the DC voltage for HVDC transmission requires the development of high-power and high voltage converters, which presents a technical challenge. This research makes use of an isolated cascaded dual active bridge (DAB) DC-DC converter to boost medium DC voltage to HVDC. Isolated Cascaded DAB DC-DC Converters are connected in series on the output side and in parallel on the input side to obtain a high transformation ratio and high power. The bidirectional DAB DC-DC converters cab be designed with power densities in the variability of tens to hundreds of kilowatts, depending on the components used and the switching frequency at which the converters function most effectively. The input parallel output series (IPOS) topology, 225 kV HVDC can be generated from a 5 kV MVDC input by cascading DAB DC-DC up to 30 stages. This converter family is useful due to its scalability and flexibility, since the power and voltage ratings can be increased while still using the same cells. MATLAB Simulink simulations are performed and verified the elementary operating characteristics of the system.

Published: August 2023

Las instituciones de Educación Superior (IES) desempeñan un papel decisivo para resolver los problemas económicos, sociales y medioambientales que afectan a la humanidad. De ahí que el logro de los Objetivos de Desarrollo Sostenible (ODS) constituya un reto para la academia. En este ámbito, el profesorado universitario tiene un rol determinante, ya que de sus conocimientos dependerá la conciencia y la cultura sostenible de los profesionales y líderes del futuro. En base a ello, este estudio se propuso identificar el nivel de conocimientos del profesorado universitario sobre los ODS y constatar las posibles diferencias existentes según el sexo y la facultad de procedencia. Para ello, se contó con la participación de 100 docentes de las Facultades de Educación y Ciencias de la Universidad de Alicante, quienes cumplimentaron un cuestionario sobre dicha temática. Se realizó un análisis descriptivo y comparativo con el programa estadístico SPSS v. 22. De acuerdo con los resultados, si bien el profesorado tenía una idea general sobre la sostenibilidad, sus conocimientos específicos eran limitados. Además, no se apreciaron diferencias significativas según el sexo y centro de adscripción. Se concluye que es necesario promover políticas universitarias para diseñar e implementar programas formativos específicos en materia de sostenibilidad.
Trabas para la formulación de postgrados y especializaciones en género y disidencias en el contexto universitario Chileno
Authors: Cornejo-Espejo Juan
Published: August 2023

El presente artículo de corte ensayístico, tiene como propósito problematizar y reflexionar acerca de las trabas económicas, burocrático – administrativas, pero sobre todo ideológico - religiosas que obstaculizan el desarrollo y fortalecimiento del postgrado en el área del género y disidencias; pues, pese a los discursos que apelan a la diversidad e inclusión, a los avances legislativos en materia de derechos individuales y colectivos, y a la voluntad política de ciertos sectores progresistas nos deparamos con fuerzas reaccionarias que intentan por distintas vías, incluida la política, nos sólo obstruir esos avances, sino revertirlos. Entre las principales conclusiones destacan: el rechazo visceral a los estudios de género y reivindicaciones feministas y de disidencias de parte de las universidades confesionales. El rezago de las universidades privadas donde el género irrumpe como un mandato de la autoridad y no producto de procesos de maduración y discernimiento de las comunidades universitarias. Y la actitud ambivalente de las universidades públicas laicas que evidencian el mayor desarrollo institucional en el área, a la vez que escaso o nulo interés por el fortalecimiento del postgrado y estudios de género y disidencias. Igualmente, relevante es el intervencionismo político y amedrentamiento de ciertos parlamentarios a académicos/as que cultivan estas disciplinas.

Published: August 2023

Em decorrência da crise sanitária mundial causada pelo novo coronavírus (SARS-Cov-2), lugares de convivência coletiva como parques e áreas verdes ficaram temporariamente proibidos de serem frequentados, fazendo com que a relação com a natureza se tornasse mais restrita. Diante desse contexto, o estudo teve por objetivo investigar as experiências das crianças na natureza durante a pandemia. Para essa investigação, de cunho qualitativo, foi elaborado um formulário eletrônico, o qual foi divulgado em diferentes mídias sociais. Essa primeira fase da pesquisa teve o intuito de compreender como estavam sendo as experiências das crianças na natureza. Posteriormente, foram realizadas entrevistas com os participantes interessados em dar continuidade a pesquisa, com o intuito de investigar a mudança de hábitos e costumes cotidianos das crianças no período de flexibilização. Os resultados das duas fases da pesquisa revelaram que a falta de contato com a natureza se agravou com a pandemia, indicando mudanças comportamentais e de hábitos na rotina e vida das crianças.

The effective method of teaching CEFR reading comprehension makes students to have better exposure and gain confidence in Malaysian secondary schools. The ultimate goal of this study is to investigate whether the use of Bubble Map and Tree Map methods enhances students’ learning of Multiple-Choice Questions (MCQ) in the CEFR reading comprehension. This quantitative study employed a quasi-experimental design. The sample of this study consisted of 105 Form One students (13 years old) from three different schools (school A, B and C) from Petaling Jaya, Selangor. The sample were chosen as intact groups. The Experimental Group 1 (EG1) from school A was taught using Bubble Map, Experimental Group 2 (EG2) from school B was taught using Tree Map and the Control Group (CG) from school C was taught using conventional method. The pre-test and post-test were used as instruments to collect the data for this study. The quantitative data was analyzed using SPSS program for Windows version 26. The MANCOVA test and Tukey HSD were used to analyze the data. The findings demonstrated that EG1 (using Bubble Map) significantly outperformed EG2 and CG in their CEFR reading comprehension. The results also indicated that EG2 (using Tree Map) performed significantly better than CG (using conventional method). This study has essential pedagogical implication because the Bubble Map and Tree Map methods had positive effects in enhancing students’ CEFR reading comprehension. As such, teachers can use Bubble Map and Tree Map methods as an alternative method to teach CEFR reading comprehension in the ESL classroom.

This paper aims to investigate the use of silence during interactions in the English language, cross-culturally, to determine if it is as effective as speech. It seeks to shed light on how British, American, Irish, and Canadian interlocutors use and interpret different types of silence and the functions it fulfills. The hypothesis posits that silence is universally employed by all interlocutors in all cultures and enhances the dynamics of interaction. The data consists of conversations from fifteen video-recorded English TV interviews, adopting Saville-Troike's (1985) and Nakane's (2007) models of analysis. The study concludes that silence serves the function of speech in transmitting and receiving messages, facilitating the aim of communication. Moreover, interlocutors from different cultures within the same language employ silence universally. Verbal and nonverbal communications, including silence, are inseparable, each playing a significant role. Their combined usage enhances the power of communication. Silence serves various functions beyond mere acceptance and refusal; it also encompasses face-saving and face-threatening strategies. Regarding cross-cultural differences in using silence in English, British interlocutors recorded the highest use of silence, followed by Americans, then the Irish, and lastly the Canadians. In addition, the use of silence varies depending on the context of the situation, the conversation's topic, the personalities of the interlocutors, their age, and their level of education.
Discourse Competence as an Essential Variable in Developing Grade 11 English First Additional Language Learners’ Writing Skills
Authors: Matiso Nomasomi Hilda , Tyantsi Olwethu
Published: August 2023

Discourse competence, which entails the interrelatedness of concepts in sentences in spoken and written language, is essential in the development of learners' receptive and productive English skills. Learners with excellent discourse competency skills can better grasp spoken and written texts on a local and global level. The main objective of this paper was to investigate the impact of discourse competence in grade 11 English First Additional Language (EFAL) learners’ writing skills. Halliday and Hassan’s Model of Evaluation framework, which advocates that the primary means of linking texts in discourse is through lexical cohesion, underpinned this study. This paper adopted an interpretivist paradigm. A qualitative approach was employed and a case study design was used to gather data from 40 purposely selected grade 11 learners. Document analysis was used. Findings indicated that (i) restricted knowledge of lexicon, (ii) inadequate knowledge about reiteration and collocation, and (iii) insufficient knowledge about appropriate use of cohesive and coherent devices, were among the established reasons for learners’ writing deficiencies. This paper recommends that essay writing skills can best be achieved through the implementation of the proposed recent language teaching methods such as the Text-based Approach, which uses texts to teach language structures and writing skills. The Department of Education should monitor the development of writing skills from the learners’ earliest years of schooling.
Does Flipped Classroom Approach Impact on Foreign Language Classroom Anxiety of First-year Chinese Urban-rural Pre-service Teachers?
Authors: Chen Wei , Baharom Sadiah Binti , Yassin Sopia Binti Md
Published: August 2023

The present study mainly investigated the impact of the flipped classroom approach (FC) on foreign language classroom anxiety (FLCA) among first-year pre-service teachers at a Chinese university. Additionally, it examined whether the effect of (flipped or traditional) teaching approach on the language anxiety differed based on the participants' (urban or rural) educational background. To achieve these objectives, a quasi-experimental design was employed. Two classes, consisting of 60 pre-service teachers (30 from urban and 30 from rural schools) in each class, were randomly assigned to an experimental group exposed to the FC and a control group using the traditional teaching approach (TT). Both approaches were implemented in an English course over a 12-week semester. Data were collected using a Foreign Language Classroom Anxiety Scale (FLCAS) and analyzed with two-way ANOVA. The results revealed that the FC had a positive impact on the FLCA among the pre-service teachers. Furthermore, the relation between teaching approach and language anxiety of the pre-service teachers was not significantly influenced by their educational backgrounds. Consequently, the study recommended that the FC be utilized to ameliorate the language anxiety of the first-year Chinese urban and rural pre-service English teachers. Accordingly, the study provided suggestions for teacher educators, pre-service teachers, and educational institutions and authorities for potentially more effective use of the FC in the specific context. Lastly, it discussed research limitations and avenues for future studies.
Suicide Risk Assessment in a Modern Asian Adolescent Community: A Cultural-relevant Perspective
Authors: Guo Gideon Qinxian
Published: August 2023

Suicide is a serious social and psychological issue that has a devastating socio-economic impact globally. However, it remains elusive as mental health professionals grapple to formulate effective assessment and intervention strategies. Particularly, there is a dearth of cultural-relevant suicide risk assessment scales as most instruments were developed in Western culture. Even with translation and linguistic equivalence, present suicide risk assessment scales do not encompass culturally salient and relevant psychological constructs. This study adopted a socio-cultural approach to develop a suicide risk assessment with sound psychometric properties and also to capture the cultural-specific symptomatology of suicide as well as depressive Asians.
