Impact of secondary ice production on thunderstorm electrification under different aerosol conditions
Authors: Huang Shiye , Yang Jing , Chen Qian , Li Jiaojiao , Zhang Qilin , Guo Fengxia
Published: July 2024

Abstract. Aerosol and secondary ice production (SIP) processes in convective clouds are both vital to charge separation in thunderstorms, but the relative importance of different SIP processes to cloud electrification under different aerosol conditions is not well understood. In this study, using the Weather Research and Forecasting (WRF) model with a spectral bin microphysics scheme, we investigate the role of four different SIP processes in charge separation in a squall line with different cloud condensation nuclei (CCN) concentrations, including the rime-splintering process, the ice-ice collisional breakup, shattering of freezing drops, and sublimational breakup. It is found that the simulation well reproduces the macro-morphology, the occurrence location, and the eastward tendency of the storm. As the CCN concentration increases, more but smaller cloud droplets can be lifted up to mixed-phase regions. The warm rain process is suppressed, and the declined raindrop concentration leads to fewer graupel particles. In a clean environment, the shattering of freezing drops is the most important SIP process to ice production at relatively warm temperatures, and the graupel concentration can be significantly enhanced. In a polluted environment, the rime-splintering process contributes the most to the graupel and ice production at relatively warm temperatures. The ice-ice collisional break-up process contributes the most to ice production at relatively cold temperatures. The noninductive charging rates exhibit a dipole structure with upper negative and lower positive regions. The implementation of four SIP processes as well as the increase in aerosol concentration both cause an enhancement of the noninductive charging rate. However, aerosol and SIP processes have opposite impacts on the charging reversal: higher aerosol concentration results in a colder reversal temperature, while SIP processes lower the reversal level. In a clean environment, the shattering of freezing drops process has the greatest effect on the noninductive charging rate, while in a polluted environment, both rime splintering and the shattering of freezing drops processes can have a significant effect. Without any SIP process, the increase in aerosols is not capable of modifying the charge structure. It is the rime-splintering process in a polluted environment responsible for the generation of a normal charge structure. Both the addition of the SIP processes and the increase in aerosol concentration favor the enhancement of the electric field.

Abstract. This study investigates the relationship between oxygen isotope ratios (δ18O) in oak tree ring cellulose and past drought variability in Letea Forest, Romania. A δ18O site chronology spanning 1803–2020 was compiled from seven individual time series. δ18O values exhibited a significant negative correlation with moisture-related variables (cloud cover, relative humidity and precipitation) and a positive correlation with temperature and sunshine duration. This confirms that δ18O from tree rings can be a good proxy for moisture availability. The strongest correlation was found between δ18O and the August Standardized Precipitation Evapotranspiration Index for an accumulation period of 9-months (SPEI9) for central and eastern Europe. This highlights SPEI9 as a superior indicator of drought compared to individual parameters like temperature or precipitation. Using a linear regression model, we reconstructed August SPEI9 variability for the past 200 years. The reconstruction captured interannual and decadal variations, with distinct wet and dry periods. Analysis of large-scale atmospheric circulation patterns revealed a link between high δ18O values (indicating dry conditions) and a high-pressure system over the North Atlantic. Conversely, low δ18O values (indicating wet conditions) corresponded to negative pressure anomalies over Europe. Moreover, extreme values of δ18O are also associated with the prevalence of a hemispheric teleconnection pattern, namely wave number 4. This δ18O chronology and the corresponding August SPEI9 reconstruction offer valuable tools for understanding past climate variability and its relationship with large-scale atmospheric and oceanic circulation patterns.

Published: July 2024

Abstract. Data-driven techniques have shown the potential to outperform process-based models for rainfall-runoff simulation. Recently, hybrid models, which combine data-driven methods with process-based approaches, have been proposed to leverage the strengths of both methodologies, aiming to enhance simulation accuracy while maintaining certain interpretability. Expanding the set of test cases to evaluate hybrid models under different conditions, we test their generalization capabilities for extreme hydrological events, comparing their performance against Long Short-Term Memory (LSTM) networks and process based models. Our results indicate that hybrid models show similar performance as LSTM networks for most cases. However, hybrid models reported slightly lower errors in the most extreme cases, and were able to produce higher peak discharges.

Abstract. An accurate representation of the radiation budget is essential for investigating the radiative effect that clouds have on the climate system, especially in the Arctic, an environment highly sensitive to complex and rapid environmental changes. In this study, we analyse a unique dataset of observations from the central Arctic made during the MOSAiC (Multidisciplinary drifting Observatory for the Study of Arctic Climate) expedition in conjunction with state-of-the-art satellite products from CERES (Clouds and the Earth's Radiant Energy System) to investigate the radiative effect of clouds and radiative closure at the surface and the top of the atmosphere (TOA). We perform a series of radiative transfer simulations using derived cloud macro- and microphysical properties as inputs to the simulations for the entire MOSAiC period, comparing our results to collocated satellite products and ice-floe observations. The radiative closure biases were generally within the instrumental uncertainty, indicating that the simulations are sufficiently accurate to realistically reproduce the radiation budget during MOSAiC. Comparisons of the simulated radiation budget relative to CERES show similar values in the terrestrial flux but relatively large differences in the solar flux, which is attributed to a lower surface albedo and a possible underestimation of atmospheric opacity by CERES. While the simulation results were consistent with the observations, more detailed analyses reveal an overestimation of simulated cloud opacity for cases involving geometrically thick ice clouds. In the annual mean, we found that the presence of clouds leads to a loss of 5.2 W m-2, of the atmospheric-surface system to space, while the surface gains 25 W m-2, and the atmosphere is cooled by clouds by 30.2 W m-2, during the MOSAiC expedition.
Reconciling post-orogenic faulting, paleostress evolution and structural inheritance in the seismogenic Northern Apennines (Italy): Insights from the Monti Martani Fault System
Authors: Asti Riccardo , Bonini Selina , Viola Giulio , Vignaroli Gianluca
Published: July 2024

Abstract. Structural inheritance plays a significant role upon the evolution of fault systems in different tectonic settings. Both positive reactivation of pre-orogenic extensional faults and negative reactivation of syn-orogenic reverse faults during orogenic cycles have been extensively studied and documented. By contrast, only few studies have addressed the impact of structural inheritance in regions undergoing polyphase tectonic histories. Here, we present the Monti Martani Fault System (MMFS) case study (Northern Apennines, Italy) as an example of a seismically active region where it is possible to investigate the role of inherited pre-orogenic structural features upon the post-orogenic tectonic evolution. Based on new field structural data from extensional faults that controlled the Plio-Quaternary evolution of the system, we propose that the MMFS does not consist of a kilometer-long L-shaped single normal fault, as previously proposed in the literature, but is instead a set of several NW-SE trending shorter extensional faults arranged in an en-echelon style. Paleostress analysis yielded three distinct extension directions during the Plio-Quaternary post-orogenic extension, which are NE-SW, NNE-SSW and NW-SE. We relate the first two directions to local orientation fluctuations of the regional stress field interacting with moderately oblique inherited structural features, and the latter direction to a short-live orogen-parallel extensional event whose geodynamic causes remain unclear. We suggest that the NE-SW regional post-orogenic extension direction controls the strike of most of the NW-SE Apenninic-trending extensional faults, while the morphostructural trend of the Monti Martani Ridge and of its boundaries with the surrounding Plio-Quaternary Medio Tiberino and Terni basins is controlled by the strike of the ~N-S and ~E-W pre-orogenic (Jurassic) inherited structural features. We also discuss the implications of these observations upon the seismotectonics of the MMFS. Our findings suggest that, in contrast to previous suggestions, the fault system cannot be classified as an active and capable structural feature.

Published: July 2024

Abstract. The efficiency of wind turbine drivetrains is a topic of great interest for both the wind energy industry and the academic community. With the developing maturity of this technology and the increasing pressures to reduce costs, the importance of drivetrain efficiency has grown. However, insufficient accuracy in torque measurement makes actually determining the efficiency of wind turbine drivetrains a very challenging task. In the project known as WindEFCY, state-of-the-art measurement and calibration instruments are used to determine the drivetrain efficiency of a direct drive wind turbine on the nacelle test bench called the DyNaLab. This paper discusses the test configuration applied for this work as well as the instrumentation of the measurement systems used. It further presents the results from two tests of different types to demonstrate the process of efficiency determination and the analysis of uncertainty. Within the paper’s scope of study, an uncertainty level of approximately 0.7 % is achievable when measuring drivetrain efficiency. Details and recommendations concerning data processing and uncertainty analysis are also given in the paper.
Large-scale systematic review support for guideline development in diabetes precision medicine
Authors: Björklund Maria , Aronsson Krister
Published: July 2024

Background: Involving librarians as team members can lead to better quality in reviews. To improve their search results, an international diabetes project involved two medical librarians in a large-scale project planning of a series of systematic reviews for clinical guidelines in diabetes precision medicine.
Case Presentation: The precision diabetes project was divided into teams. Four diabetes mellitus types (type 1, type 2, gestational, and monogenic) were divided into teams focusing on diagnostics, prevention, treatment, or prognostics. A search consultation plan was set up for the project to help organize the work. We performed searches in Embase and PubMed for 14 teams, building complex searches that involved non-traditional search strategies. Our search strategies generated very large amounts of records that created challenges in balancing sensitivity with precision. We also performed overlap searches for type 1 and type 2 diabetes search strategies; and assisted in setting up reviews in the Covidence tool for screening.
Conclusions: This project gave us opportunities to test methods we had not used before, such as overlap comparisons between whole search strategies. It also gave us insights into the complexity of performing a search balancing sensitivity and specificity and highlights the need for a clearly defined communication plan for extensive evidence synthesis projects.

Published: July 2024

The More Electric Aircraft (MEA) paradigm advocates weight reduction by transitioning to electrical components, resulting in increased system voltage and higher arc fault risk. This paper presents a methodology for creating a database of nearly one thousand tests simulating parallel arc faults, using Andrea's arc model for accurate representation. Objectives include the creation of a robust experimental database and the use of a simplified model to analyze arcing behavior. The setup follows the UL 746A standard and considers various pressure and electrode separation conditions. The database includes 960 experiments with PVC and PTFE materials, and model fitting ensures accurate representation of arc currents and voltages. Error analysis shows consistent model performance across materials and highlights sensitivity to electrode spacing, pressure, and source voltage. The paper concludes with a clear 30% error threshold for model validity, enhancing the understanding of the applicability of Andrea's model under various experimental scenarios in aircraft environments.

Published: July 2024

In Benin, maize production is important for food security and rural household incomes. However, it is subject to climatic variations that induce low yields and productivity levels. This innovative study categorizes the energy sources used in its production to identify levers for improving agricultural productivity. A survey of 230 maize growers in the communes of N'Dali, Sinende and Nikki was carried out. Data were collected using structured questionnaires on farming activities and input use, then converted into energy values using energy equivalence coefficients collected in previous studies. The results reveal a high level of awareness among maize growers (97.4%) of the impacts of climate change on maize production. In terms of the amount of energy derived from labor power, mechanical plowing stood out (133.02 MJ/ha), closely followed by animal-drawn plowing (53.04 MJ/ha) and harvesting (45.18 MJ/ha). In terms of inputs, NPK fertilizer stands out with an energy expenditure of 2238.87 MJ/ha, followed by urea with 1172.95 MJ/ha. Although increasing labor power remains the approach most adopted (61%) by growers to maintain the productivity of their farms, the results revealed a predominance of energy from agricultural inputs (94.91% of total energy), underlining the preponderance of inputs in overall energy requirements.

Authors: Öğraş Emre Bülent , Çetın Mehmet Çağrı
Published: July 2024

This study aims to examine the mental toughness, goal orientation and motivational climate levels of 887 professional footballers from TFF 1st League, TFF 2nd League and TFF 3rd League registered in Turkish Football Federation and whether these characteristics change according to age, league level and sport experience. The results showed that mental toughness scores of footballers were significantly correlated with age, league level and sport experience. Significant difference was found in goal orientation scores with age and league level, but not with sport experience. Motivational climate scores were found to vary significantly with age, league level and sport experience. In addition, it was found that task orientation had a positive effect on mental toughness, and mastery climate, one of the sub-dimensions of motivational climate, had a positive effect on mental toughness. However, performance climate was found to have a significant and negative effect on mental toughness. This study showed that the levels of mental toughness, goal orientation and motivational climate in professional football players have significant relationships with demographic factors and with each other.

A comparison of the neuropsychological profile of children who have fetal alcohol spectrum disorder and autistic children. Differences in social cognition and the relevance to assessment and diagnosis
Authors: Saveker Sarah
Published: July 2024

This article explores the neuropsychological profile of autism and fetal alcohol spectrum disorder. These distinct conditions can have a similar presentation, and there is increasing interest in distinguishing between the neurobehavioural presentations as part of assessment and diagnosis. Although there are similarities in the neurodevelopmental profile of autism and fetal alcohol spectrum disorder, there are discreet differences in social cognition that may be useful to consider during assessment. This article argues that neuropsychological assessment of social cognition, as well as executive functions including inhibitory control, will be useful when considering a diagnosis, as these factors may underpin differences caused by prenatal alcohol exposure, or autism. Research in this area is in its infancy, and more investigation is needed.

Formulation can be a helpful way of developing a shared understanding of a person’s needs and strengths. Formulation has been linked with a better care experience and better treatment outcomes. However, there can be challenges in developing and sharing formulations within busy community treatment teams (CTTs). An older adult CTT trialled the use of an assistant psychologist (AP) to create and oversee a formulation referral process, and to facilitate and embed formulation sessions using the 5Ps model. The current study investigates clinicians’ perspectives on the acceptability and effectiveness of using the 5Ps model, and the utilisation of an AP to organise, facilitate and document formulation sessions.

Published: July 2024

Background: The aim of this study was to evaluate the impact of mental health attributes, such as the presence of psychiatric comorbidities or psychological comorbidities (low resilience), on outcomes after rotator cuff repair (RCR) and total shoulder arthroplasty (TSA).Methods: PubMed, Cochrane, and Google Scholar (results pages 1–20) were searched up to November 2023. Mental health problems of interest included the presence of psychiatric comorbidities (depression, anxiety) or indicators of poor psychological functioning, such as low resilience or the presence of distress. Patients were assigned to poor or good mental health groups in this study based on their grouping in the original study.Results: Fourteen studies were included in the meta-analysis. Patients with good mental health had greater improvements in postoperative American Shoulder and Elbow Surgeons and Simple Shoulder Test scores in the TSA cohort (P=0.003 and P=0.01), RCR cohort (P<0.001), and the combined TSA and RCR cohort (P<0.001). No difference was found in visual analog scale score, satisfaction, external rotation, or flexion between the two mental health groups. Patients with poor mental health undergoing RCR experienced higher rates of adverse events and transfusions (P<0.001). Patients with poor mental health also had greater rates of revision and emergency department visits in the TSA cohort (P<0.001), RCR cohort (P=0.05 and P=0.03), and combined cohort (P<0.001). Patients with poor mental health undergoing TSA had a higher rate of re-admission (P<0.001).Conclusions: Patients with poor preoperative mental health showed inferior patient-reported outcome scores and increased rates of adverse events, revisions, and re-admissions.Level of evidence: III.
A Quest for Malaysian Environmental Justice in Yang-May Ooi’s The Flame Tree
Authors: Praphan Kittiphong , Khamkhong Surasak
Published: July 2024

This study aims to investigate the environmental agenda in The Flame Tree, an English novel by Yang-May Ooi, a Malaysian-British author. The concepts of environmental justice and environmental racism are employed in the analysis. Through the main characters and incidents in the novel, Ooi suggests that Malaysian local people suffer greatly from a lack of environmental justice in their community as a result of the manipulation of a transnational corporation operated by a global capitalist, who commits crimes in different forms to win a mega project under the policy for the country’s modernization. This mega project eventually causes an environmental apocalypse and a tragedy for the local people who do not have an opportunity to participate in the decision-making process regarding this project. Based on environmental racism, the local Malaysian people endure disruptions from the project initiated by the British race, the former colonizers of Malaysia, who aim to reap its full benefit. Despite the end of British Imperialism, the power relation between the British and the Malaysians persists. This novel protests against transnational environmental crime which leaves detrimental effects on the Malaysian land and people.
Measuring the Impact of Written Corrective Feedback (WCF): The Methodological ins and outs
Authors: Carcamo Benjamin
Published: July 2024

The interest in the study of written corrective feedback (WCF) has led to the identification of two controversial areas: the impact of the different types of WCF and the methods used in the studies. The present study aims to contribute to the clarification of the latter by examining the methods section of recently published research articles. Its objective is to review the current state of the experimental research designs in WCF studies. For this, eleven published studies were randomly selected and analyzed considering as inclusion criteria that they were empirical studies published in journals indexed in Web of Science and/or Scopus during the last eight years. The findings have been grouped into two categories: research designs and data analysis procedures. Regarding research design, there is a growing concern for ecological validity, the inclusion of delayed post-tests, and the implementation of training on feedback types for students. Concerning data analysis, the choice of a specific formula for error quantification was identified as a crucial decision researchers interested in WCF must make. It is hoped that this study will guide future research, ensuring a solid methodological design in line with current publications in prestigious journals. By following the trends identified in recent prestigious research, it is more likely that research can address the concerns surrounding the effectiveness of different types of WCF.
The Influence of Social Media on Improving the Pragmatic Skills of EFL Saudi University Students
Authors: Almehmadi Wesam
Published: July 2024

Social media platforms can be a gateway through which English as a foreign language (EFL) students gain access to the world of the target language, communicate with native speakers, and learn more about their culture. Against this background, the present study aims to investigate whether EFL students’ use of social media has impacted the development of their pragmatic competence and conversational skills. Sixty Saudi EFL students, aged 17 or older, studying in the English Language and Translation Department at the Saudi Electronic University participated in the study. Data were collected through an online questionnaire that assessed the participants’ perceptions of using social media networks to practice their English conversation skills. The results showed that social media use had a positive impact on the students’ pragmatic and conversational skills. Specifically, a significant proportion of the participants reported an awareness of conversational and pragmatic improvements resulting from social media use that may not be available in traditional classroom settings. These findings suggest that technology-assisted language learning, particularly learning using social media, should be incorporated into language instruction to improve EFL students’ pragmatic and conversational knowledge. In this regard, social media networks are especially valuable in providing authentic and meaningful language and interaction opportunities. Future research could examine other forms of technology-assisted language learning beyond social media and employ a mixed-methods approach to gain a more comprehensive understanding of the impact of mobile-assisted language learning (MALL) on EFL learners’ pragmatic and conversational proficiency.
Historicizing Brati: A Journey of Sujata’s Memories in Mahasweta Devi’s Mother of 1084
Authors: Samuel A Stephen , Priscilla B Evangeline
Published: July 2024

Mahasweta Devi’s Mother of 1084 has a trope of returning to the past events, after a tragedy. This trope is central to both the plot and act of narration of the protagonist, Sujata. Sujata’s journey to the past is not just part of a thematic element, but also a narrative strategy through which Mahasweta Devi casts an indirect gaze on the Naxalite world. This study analyses Sujata’s trip into the past by focusing on different subsets of memory involved in her journey which Mahasweta Devi employs throughout the novel. Devi’s Mother of 1084 entirely is a narrative from the perspective of a bereaved Sujata after having lost her son Brati to unknown circumstances. By referring to the theoretical underpinnings of renowned scholars from the field of Memory Studies, including Jacques Lacan, Endel Tulving, Chris Brewin, and Kurt Danziger, this study explores how different memory subsets that of recollection, reminiscence, episodes, semantics, and flashbacks of the characters in the novel come together to historicise the memory of the deceased (Brati). The study then attempts to understand memory’s role as the focal point in bringing an artistic sense to the novel.

Verbally Expressed Humor (VEH) is a form of humor that through language, written or spoken, to create comic effects. VEH translation in audiovisual products has been a great challenge due to the cultural and linguistic gap in target culture, and the translation inaccuracy and bias bring confusion to audience. Besides, though various methods have been utilized in investigating VEH translation strategies in subtitling and dubbing, no agreed-upon strategy suggestion for each category of VEH. In the present study, systematic literature review methodology is applied to examine related studies published until 1 January 2024, sourced from Web of Science (WoS) collection and Scopus. 35 articles are selected under the guideline of PRISMA 2020 and eligibility criteria. In general, the study aims to examine research status on VEH translation in audiovisual products. Specifically, it tends to clarify what translation strategies are used in translating VEH. The review indicates that: 1) English has been explored most frequently as the source and target language in studies of VEH translation in audiovisual products. 2) The major humor type examined in the selected studies is wordplay. 3) The VEH translation can be guided by various translation strategies taxonomies, while the slight adaptation or change is usually required. 4) Gottlieb’s (1992) taxonomy of translation strategies has been extensively utilized in the translation of VEH. However, there remains an absence of a standardized set of translation strategies that can be universally applied to any specific category of VEH. The findings can discover research gap and future trends for researchers, providing VEH translation advice for translators.

Published: July 2024

This study investigates the impact of motivational factors on the reading test performance of Chinese learners in the IELTS examination. The objectives are to evaluate the motivation levels, analyze the relationship between motivation and IELTS reading achievement, and identify the most influential predictors among intrinsic and extrinsic motivations. Using a quantitative research design and a sample of 242 students from 12 IELTS training centers in southwest China, data were collected through the Motivation in English Reading Questionnaire (MERQ) and Cambridge Practice Tests for IELTS. Pearson correlation coefficients and multiple regression analysis were employed to analyze the data. The results show significant positive correlations between various motivational constructs and IELTS reading scores. Total motivation (r = .634, p < .001), efficacy and engagement (r = .520, p < .001), utility value (r = .459, p < .001), and academic value (r = .424, p < .001) are all positively associated with reading proficiency. Regression analysis indicates that intrinsic motivation, specifically efficacy and engagement (β = 0.504), is the strongest predictor of reading scores, followed by utility value (β = 0.351) and academic value (β = 0.315). These findings underscore the essential role of both intrinsic and extrinsic motivations in improving reading proficiency among Chinese IELTS learners.

The Effect of Multimedia on Vocabulary Learning and Retention
Authors: Alhazmi Khaled
Published: July 2024

Acquiring vocabulary is essential for learning a foreign language. Comparing multimedia approaches that combine text, graphics, audio, and video with standard text-only methods may improve vocabulary learning. The impact of multimedia on vocabulary learning and retention is examined in this study. Fifty undergraduate English learners were split into two groups using a mixed experimental design. Video clips, graphics, and text were used to teach vocabulary to the experimental group. All participants completed pre post vocabulary tests to assess learning and retention. Multimedia instruction led to significantly higher vocabulary gains on the immediate test compared to text-only instruction. Moreover, multimedia learning promoted greater long-term retention based on higher scores on the post test. These findings were consistent across different categories of concrete and abstract words. Additional analysis found multimedia was particularly beneficial for learners with lower verbal working memory capacity. The results suggest multimedia capitalizes on dual coding and provides contextual support which enhances both initial vocabulary learning and retention. This multimedia effect persisted over time, indicating potential pedagogical benefits. The study contributes to theories of multimedia learning and vocabulary.
