One of the goals of Space Weather studies is to achieve a better understanding of impulsive phenomena, such as Coronal Mass Ejections (CMEs), to improve our ability to forecast their propagation characteristics and mitigate the risks to our technologically driven society. The essential part of achieving this goal is to assess the performance of forecasting models. To this end, the quality and availability of suitable data are of paramount importance. In this work, we merged publicly available data of CMEs from both in-situ and remote observations in order to build a dataset of CME properties. To evaluate the accuracy of the dataset and confirm the relationship between in-situ and remote observations, we have employed the Drag-Based Model (DBM) due to its simplicity and modest consumption of computational resources. In this study, we have also explored the parameter space for the drag parameter and solar wind speed using a Monte Carlo approach to evaluate how efficiently the DBM determines the propagation of CMEs for the events in the dataset. The geoeffective CMEs selected as a result of this work are compliant with the hypothesis of DBM (isolated CME, constant solar wind speed beyond 20 R⊙) and also yield further insight into CME features such as arrival time and arrival speed at L1 point, lift-off time, speed at 20 R⊙ and other similar quantities. Our analysis based on the acceptance rate in the DBM inversion procedure shows that almost 50% of the CME events in the dataset are well described by DBM as they propagate in the heliosphere. The dataset includes statistical metrics for the DBM model parameters. The probability distribution functions (PDFs) for the free parameters of DBM have been derived through a Monte Carlo-like inversion procedure. Probability distribution functions obtained from this work are comparable to PDFs employed in previous works. The analysis showed that there exist two different most probable values (median values) of solar wind speed for DBM input based on slow (wslow ≈ 386 km/s) and fast (wfast ≈ 547 km/s) solar wind type. The most probable value for the drag parameter (γ ≈ 0.687 × 10−7 km−1) in our study is somewhat higher than the values reported in previous studies. Using a data-driven approach, this procedure allows us to present a homogeneous, reliable, and robust dataset for the investigation of CME propagation. Additionally, possible CME events are identified where the DBM prediction is not valid due to model limitations and higher uncertainties in the input parameters. These events require further thorough investigation in the future.

Authors: Singh Shamer , Singh Gurpreet 
Published: February 2024

SummarySingle oral administration of 100,000 IU of vitamin A palmitate in oil to pregnant wistar rats on 8th, 9th or 10th day of gestation resulted in malformations of the tongue, jaw; lower lip and palate in 82%, live-born foetuses. The frequency and severity of defects were most marked in the group treated on the 9th day. Clefts of the jaw, lip, tongue and palate were practically coufined to the 9th day treated group. Of great interest were the clefts in the lower lips which varied from a mere chink to a wide gap splitting the lower jaw as well. The cleft tongue protruded through the gap and folded on itself, giving a false appearence of muitiple clefts in the lower lips.

Published: February 2024

SummaryThe present study was conducted on 56 cases of cleft palate and/or lip attending the Rehabilitation Unit in Audiology and Speech Pethology, All India Institute of Medical Sciences, New Delhi. Cleft palate was found to be more prevalent in males than females. 75% of the cases were below the age of 14 years, Only a few parents could give relevant history. It was, therefore, difficult to establish and generalise the causative factors. 29% of the cleft palate cases had mild to moderate degree of hearing loss. About 42% of the cases had undergone palate surgery and 35% both the lip and palate surgery. Many cases reported late for surgical treatment. Velar sounds among all the consonants were found to be substituted most and fricatives were distorted. Distortion was the most common defective articulatory pattern in the cleft palate cases while omissions were least affected. There has been numerous investigations designed to describe the speech articulation on cleft palate. The studies vary in terms of subjects used and the methods of assessment. Yet there is a general agreement on this problem. Plosives, fricatives and consonants which require building up of maximum oral pressure are the most affected sounds in cleft palate speech.

Use of Local Flaps in the Management of Recurrent Recto-Veginal Fistula (With Imperforate Anus)
Authors: Gupta Malti , Chandalia B. S. 
Published: February 2024

SummaryWe recommend local flaps in the management of recurrent rectovaginal fistula for following reasons:(i) The flap brings healthy vascular tissues to the site of fistula where lot of fibrosis is present following previous operations, thus healing of tissues is promoted.{ii) It reinforces the site of repair by being interposed posterior to the posterior vaginal wall.(iii) It enlarges the anal opening in cases with anal stenosis unresponsive to routine treatment.(iv) It brings additional skin between the anal and vaginal openings, thus maintaining them at normal distance in those cases where the openings are situated close together with very little, hypoplastic tissue in between.The flap, unlike split skin graft, grows with the growth of the body, so that chances of future stenosis and recurrence are nil. This is important particularly in children.(vi) The procedure is comparatively simple and safe, more so in the under nourished child, and makes major surgical procedures unnecessary.(vii) The duration of hospital stay is markedly curtailed and so is the economic burden of prolonae hospitalisation.

SummaryPresent study is based on the observations of 25 cases of oral cancer. Males are affected more commonly in S5th and 6ih decade. Clinical lymphadenopathy in the neck is observed in 84% of cases which was confirmed on hisiology in only 56% cases. Clinically the disease is more advanced than its histological grade. Inflammatory infiltrate in the primary tumour and germinal centre hyperplasia, paracortical activity and sinus histiocytosis in the Iymphnodes are suggestive of immunological response against the tumour whereas capsular and pericapsular invasion of lymph nodes are suggestive of poor prognosis.
China’s shadow banking in 2020–2022: an empirical study
Authors: Li Wenzhe 
Published: February 2024

AbstractDespite renewed regulatory attention, shadow banking across the globe is still a nonnegligible part of economic life. This paper researches China’s shadow banking during 2020–2022, a stage marked by COVID-19 and strengthened global regulation on Non-Bank Financial Intermediation (NBFI). Its business model surprisingly resembles its Western peers, funding underserved sectors and having similar exposure to balance sheet mismatch. Uninsured interbank funds and wealth management products support massive holding of bond investment (36.6% of the total assets), making risk contagion easier. This paper re-summarizes growth dynamics in a “Pull-Push” framework and proposes the concept of reintermediation corresponding to disintermediation. Consecutive regulation on NBFI and the real estate sector kept dragging on growth, rendering it in liquidity surplus. We provide empirical evidence on the relationship of China’s shadow banking with macro-finance and note several breakdowns of pre-pandemic relations among economic and financial indicators. The most remarkable breakdown is the weakened functionality of the monetary policy transmission channel. Besides, it continued to twist financial regulatory indicators to a lesser extent.
Risk assessments of virtual interactions on Saudi families
Authors: Moubarak Hanaa Faize A. , Afthanorhan Asyraf 
Published: February 2024

AbstractFamily relationships are the basis for a stable family atmosphere. Now with the internet, which has become a tangible part of our lives, membership of virtual communities, including social networks, has grown. It has created fundamental changes in the structure of social relationships and human interaction, forming a new framework of virtual interactions that transcend international borders. Due to their significance, unavoidability, availability, confidentiality, ease of use, and intrusive nature through interaction and sharing, virtual communities now extend beyond the individual and related level of risk. This study aimed to assess the cultural and behavioral risks of virtual interactions for Saudi families and their level of incidence and likelihood. It belonged to descriptive studies, using the social survey for a sample (1524) from Hail region families between 15 December 2022 and 31 January 2023, and was based on the list of cultural and behavioral risks of virtual interactions. Results showed that the most dangerous social networking sites for Saudi families were TikTok, Twitter, Snapchat, YouTube, and Instagram respectively. Matrix results showed that 66.7% of virtual interaction threats have a high severity and likelihood, namely: adopting atheistic ideas, spreading the thought of hate, undermining the values of the Saudi family, and adopting ideas that incite violence from cultural threats, privacy hacks, cyber-bullying, fraud, violence, social isolation and cybercrime from behavioral threats. The study recommends adopting a social risk management (SRM) concept, especially regarding risks to family, because it is a new dimension of social protection.
A corpus-based comparison of linguistic markers of stance and genre in the academic writing of novice and advanced engineering learners
Authors: Barbara Siu Wing Yee , Afzaal Muhammad , Aldayel Hessah Saleh 
Published: February 2024

AbstractStance-taking in academic writing plays a crucial role in enabling tertiary academic writers to express their positions about their topics and other voices. Based on a corpus linguistic analysis of academic reports by civil and environmental engineering (CEE) undergraduate students and student papers in the Michigan Corpus of Upper-Level Student Papers (MICUSP), this article investigates the use of stance markers in the genres of persuasive and argumentative writing as well as analytical explanatory writing. This study compares the stance markers used by L2 engineering students (Hong Kong University) and native engineering students (U.S. University) to investigate the genre-specific lexical stance patterns used by academic writers. This study found that stance within the CEE reports and MICUSP was expressed through approximative hedges and boosters, code glosses, and adversative and contrast connections, pointing to a specific developmental trajectory as academic writers. Non-native engineering students were found to use a significantly smaller number of approximative, self-mention, and evidential verb hedges. In addition, they tend to use a more significant number of modal hedges compared to native English speakers. The CEE students’ reports also tended to be characterized by the underuse of boosters, contrastive connectors, emphasis, and counter-expectancy markers. However, the study found no significant difference in the use of exemplification markers between the CEE and MICUSP. The findings of this study support the construction of the academic stance as a process of delimiting one’s perspective. This is achieved by deploying selected stance features to account for other scholarly perspectives.

Published: February 2024

AbstractInformation and communication technology (ICT) has become increasingly important worldwide in education. This study aims to recognize the factors that influence the intention to use information and communication technology (ITUICT) and its acceptance in the education sector in China. A literature review was conducted to ascertain the potential factors such as perceived awareness, information acquisition, trustworthiness, social influence, and regulatory support that could affect the acceptance and ITUICT. For results, a survey was conducted on a sample of 381 university employees in China using a convenience sampling approach. The collected data were analyzed using partial least squares-structural equation modeling (PLS-SEM). The results show that individual factors such as perceived awareness, information acquisition, trustworthiness, social influence, and regulatory support significantly impact the ITUICT. Additionally, trustworthiness positively moderates the relationship among perceived awareness, information acquisition, social influence, regulatory support, and ITUICT. Policymakers and educators can use the findings of this study to enhance the adoption of ICT in China’s education sector. The results of this study suggest that it is important to provide educational sector employees with training and support to increase their use of ICT technology. Furthermore, this paper offers theoretical progression to create a supportive organizational culture and provide the educational sector with the necessary technological resources to facilitate the use of ICT.

AbstractAs museums continue to play an increasingly significant role in the preservation, innovation, and dissemination of cultural heritages, the products sold in their souvenir shops have become a vital carrier of cultural and creative industries. The creativity of these products has drawn intensive attention from various industries. However, the evaluation of museum products’ creativity still lacks objectivity, scientific rigour, and systematisation. This study aims to construct a contextual and comprehensive measurement model to evaluate the creativity of products purchased in souvenir shops affiliated with urban historical museums in China. Based on the literature, ten related hypotheses were introduced, and a conceptual model was illustrated. Six relevant dimensions and 28 corresponding indicators were identified, and then a 7-point Likert-styled questionnaire was developed. An online survey was conducted, which invited 931 participants to take part. Among them, 708 responses are valid (rate 76.05%). The overall reliability of the survey is 0.96 (Cronbach’s α). Then, exploratory factor analysis, confirmatory factor analysis and a structural equation modelling analysis using SPSS and SmartPLS were conducted. The results supported most hypotheses proposed by this study and confirmed the validity of the museum product creativity measurement (MPCM). The validated instrument comprises five dimensions: Affect, Usefulness, Aesthetics, Cultural Values and Novelty, with a total of 21 indicators. Additionally, the findings revealed that Aesthetics mediates Affect, and Cultural Values mediate Usefulness. Moreover, a negative moderating effect of Educational Level on the perception of Cultural Values was detected.
