English-medium instruction as an internationalisation strategy at a second-tier Chinese University: instructors’ challenges and their shaping factors
Authors: Zheng Qun , Choi Tae-Hee 
Published: October 2024

AbstractJoining the tide of global internationalisation of higher education, Chinese universities have embraced English-medium instruction (EMI) as a strategic response. The adoption of EMI is to comply with government mandates and for institutional survival, as it will increase the international ranking and bring in more income from international students. The switch of medium of instruction and pedagogical issues arising therefrom have drawn considerable scholarly attention. However, little attention has been paid to the implementation of EMI in second- or mid-tier universities, and, particularly, to the attendant pedagogical issues. In comparison to top-tier universities, second-tier universities’ instructors must deal with amplified tensions created between the pedagogical needs and institutional requirements brought by the EMI policy. This study seeks to shed light on the challenges, and their contributing factors, confronted by educators in these universities. Employing a language policy analysis framework informed by policy enactment theory, the research draws upon an examination of both national and institutional policy documents, as well as interviews conducted with nine educators and administrative leaders across three distinct faculties. The investigation reveals that the emergent challenges in implementing EMI stem from several sources, including lax admission standards for international students and the divergent backgrounds and requirements of local versus international student populations. These findings underscore the imperative for a thorough appraisal of contextual nuances before the formulation and implementation of language-in-education policies. This is particularly salient in second-tier academic institutions, which often grapple with limited resources and may not possess the same level of preparedness to adapt their systems as swiftly as their more resourced counterparts.

Abstract
Background
Trabectedin (Tbt) is an alkylating agent prescribed for soft tissue sarcomas after treatment failure of first line agents. While cardiomyopathy can occur with Tbt treatment after anthracycline exposure, Tbt-induced fulminant myocardial cytotoxic injury in the setting of other systemic cytotoxicity associated with Tbt has not been reported.

Case presentation
51-year-old female with hypertension, hyperlipidemia, metastatic leiomyosarcoma with progression of disease despite several lines of chemotherapy including doxorubicin-based therapy was started on Trabectedin (Tbt) 5 days prior to presentation with symptoms of fever, myalgias, arthralgias, and palpitations. She was admitted for management of rhabdomyolysis, acute kidney and liver injuries which were reportedly known to be associated with Tbt treatment. A baseline electrocardiogram (ECG) revealed sinus tachycardia with non-specific T-wave changes, and a transthoracic echocardiogram (TTE) was unremarkable. However, on day 3 of hospitalization, an episode of asymptomatic sustained monomorphic ventricular tachycardia with a heart rate of 150 beats per minute was captured on telemetry. A 12-lead ECG revealed new septal T-wave inversions. Labs revealed rising hs-TnI levels (peak at 37,933ng/L) and serum markers suggested multi-organ failure. Steroids were initiated given its role in treating multi-organ Tbt-induced toxicity. A cardiac MRI to rule out myocarditis and left heart catheterization to rule out obstructive coronary artery disease were forgone due to acute renal failure. A right heart catheterization with an endomyocardial biopsy was performed revealing normal cardiac filling pressures and indices. Pathology showed cytoplasmic vacuoles indicating drug-induced myocardial cytotoxicity. Serial echocardiograms revealed preserved biventricular function. The patient’s clinical condition deteriorated with multi-organ failure despite maximal supportive care in the intensive care unit. She ultimately passed away, and an autopsy was declined.

Conclusion
This is the first reported case of fulminant myocardial injury after initiation of Tbt with histologic evidence of drug-induced myocardial cytotoxicity. While it is unclear if anthracyclines potentiate Tbt cytotoxic injury as in this case, it is plausible; and that Tbt-induced cardiotoxicity ranges from subclinical to fulminant. Given increasing use of Tbt in refractory high-grade sarcomas, raising awareness of its toxicity profile will improve early detection and outcomes.

Abstract
Background
This study aimed to assess body image dissatisfaction in Omani university students across gender and age and explore the potential impact of social media use on body image dissatisfaction. This cross-sectional online survey was responded by 482 Omani university students. The survey included socio-demographic data, a Social Media Activity Questionnaire, and a Body Dissatisfaction Scale. The participants were approached through promotion of the study on locally famous social media accounts.

Results
The prevalence of body image dissatisfaction was higher in females compared to males (37.7% and 24%, respectively). Additionally, 53.6% of participants with a high body mass index reported high levels of body image dissatisfaction, while underweight participants reported the lowest body image dissatisfaction (21.3%). High social media use showed a significant correlation with body image dissatisfaction (p < 0.001); however, age did not exhibit a significant association with body image dissatisfaction. Concerns related to being overweight and not having clear skin were the most common body features associated with body image issues.

Conclusion
Higher levels of body image dissatisfaction were found with high social media use. The study also identified a higher prevalence of body image dissatisfaction in females compared to males, with no significant differences across age groups.
Prognostic nutritional index as a predictor of mortality among patients admitted to ICU with acute exacerbation of chronic obstructive pulmonary disease
Authors: Abdel-Hamid Hossam Eldin Mohamed 
Published: October 2024

Abstract
Background
The PNI is a metric that may assess the combined impact of the inflammatory process and nutritional condition. It may be beneficial in evaluating the nutritional state of patients with AECOPD.
In recent years, it has also been utilized for prognostic assessment of cases admitted to the critical care unit.

Aim of the work
The objective of the research was to assess the relationship between PNI and the prognosis for ICU patients with AECOPD.

Patients and methods
This was a prospective cross-sectional observational research carried out in the RICU of Ain Shams University Hospitals from April 2023 to March 2024. The study included 161 AECOPD patients who were admitted to RICU. All patients underwent demographic data collection, special habits and comorbid conditions evaluations, and hematological indices with laboratory markers and ABG. ICU and hospital stay duration, SOFA score, and SAPS II were also documented. The PNI value was computed using the following equation: the formula to calculate the value is 10 times the serum albumin concentration in grams per deciliter plus 0.005 times the total lymphocyte count in cubic millimeters. The main measure of interest was the death rate within 30 days for all causes. Additional measures were the duration of stay in the ICU, the duration of hospitalization, and the rate of MV.

Results
There was a significant relationship between PNI and type of respiratory failure, mechanical ventilation, fate, hypertension, and diabetes. One hundred five (65.2%) of the patients were extubated and discharged, while 56 (34.8%) of them died. The study also noted a significant positive relationship among PNI and HCT, lymphocytic %, HB, and albumin. However, there was a significant negative relationship between PNI and age, RDW, WBC, neutrophil count, neutrophil %, NLR, CRP, SAPSII, and SOFA. The SAPS II score (with SAPS II mortality) had greater AUROC in predicting mortality than PNI, NLR, and SOFA. The optimal cut-off value for PNI in this study was ≤ 29 with sensitivity 82.14% and specificity 56.19%.

Conclusion
The study showed that PNI can be a useful biomarker for AECOPD. PNI with SAPS II scores on admission to ICU were closely correlated to adverse outcomes.
Prediction of shale bedding-parallel crack density based on the SH-SH wave

Published: October 2024

Bedding-parallel cracks play a key role in hydrocarbon accumulation and offer potential benefits for hydraulic fracturing. The prediction of bedding-parallel crack density (BCD) from seismic data is difficult because the development of bedding-parallel cracks has limited effects on the velocities and density of subsurface formations. Well logs from the Q shale formation (K2qn) in the Songliao Basin, northeast China, reveal that the target formations represent extremely strong seismic anisotropy (>40%), and the magnitude of S-wave anisotropy correlates strongly with the density of bedding-parallel cracks, reaching up to 2500 m−1. We develop a novel BCD prediction method using the reflected seismic shear wave. The S-wave anisotropy parameter [Formula: see text] is first inverted from the SH-SH wave by using a stepwise inversion method based on a new S-wave reflection coefficient approximation. Furthermore, the highly correlated rock-physics relationship between BCD and the anisotropy parameter [Formula: see text] facilitates accurate BCD estimation. Field data application to a real seismic shear wave data set acquired from the study area demonstrates the viability of our method. This approach provides a valuable tool for the characterization of “sweet spots” of shale-oil reservoir formations.
Physical health challenges faced by elders with severe mental illness: population-based retrospective cohort study
Authors: Chang Chin-Kuo , Hayes Richard D. , Broadbent Matthew , Shetty Hitesh , Su Yu-Ping , Meesters Paul D. , Stewart Robert 
Published: October 2024

Background
Severe mental illness (SMI), which includes schizophrenia, schizoaffective disorder and bipolar disorder, has profound health impacts, even in the elderly.

Aims
To evaluate relative risk of hospital admission and length of hospital stay for physical illness in elders with SMI.

Method
To construct a population-based retrospective cohort observed from April 2007 to March 2016, data from a case registry with full but de-identified electronic health records were retrieved for patients of the South London and Maudsley NHS Foundation Trust, the single secondary mental healthcare service provider in south-east London. We compared participants with SMI aged >60 years old with the general population of the same age and residing in the same areas through data linkage by age-, sex- and fiscal-year-standardised admission ratios (SARs) for primary diagnoses at hospital discharge. Furthermore, we compared the duration of hospital stay with an age-, sex- and cause-of-admission-matched random group by linear regression for major causes of admission.

Results
In total, records for 4175 older people with SMI were obtained, relating to 10 342 admission episodes, showing an overall SAR for all physical illnesses of 5.15 (95% CI: 5.05, 5.25). Among the top causes of admission, SARs ranged from 3.87 for circulatory system disorders (ICD-10 codes: I00–I99) to 6.99 for genitourinary system or urinary conditions (N00–N39). Specifically, the diagnostic group of ‘symptoms, signs and findings, not elsewhere classified’ (R00–R99) had an elevated SAR of 6.56 (95% CI: 6.22, 6.90). Elders with SMI also had significantly longer hospital stays than their counterparts in the general population, especially for digestive system illnesses (K00–K93), after adjusting for confounding.

Conclusions
Poorer overall physical health and specific patterns were identified in elders with SMI.
New Challenges: Use and Interpretation of Radius Bone Mineral Density
Authors: Cauley Jane A , Lui Li-Yung , LeBoff Meryl S , Watts Nelson B 
Published: October 2024

Abstract

Context
It is unknown if isolated low bone mineral density (BMD) “osteoporosis” at the radius is associated with increased fracture risk, not only at the wrist but elsewhere, and whether it reflects more generalized skeletal fragility.

Objective
This work aimed to review the association of radius BMD and fracture risk, the epidemiology of wrist fractures, isolated osteoporosis at the radius, and the concordance between radial BMD and femoral neck BMD.

Methods
We completed a narrative literature review on radius BMD and fracture risk and current recommendations for measurement of radial BMD. We updated results of radial BMD and fracture results from the Study of Osteoporotic Fractures over 20 years and examined the concordance of BMD at the distal and proximal radius with femoral neck BMD T scores.

Results
Radius BMD is a robust predictor of all types of fractures including hip and wrist but there is insufficient evidence to suggest that radius BMD predicts wrist fractures better than fractures at other sites. Fractures of the wrist tend to occur in younger, healthier women compared with hip and spine fractures. Nevertheless, wrist fractures are associated with an increased risk of future fractures and represent a missed opportunity for intervention. On a population level, the discordance between radius BMD and femoral neck BMD is small. But women with isolated osteoporosis at the radius had biochemical and microarchitecture deterioration that were similar to women with hip osteoporosis.

Conclusion
Future research should address the clinical implications of isolated osteoporosis at the radius and whether treatment is warranted.
A Machine Learning Framework for Assessing Experts’ Decision Quality
Authors: Dong Wanxue , Saar-Tsechansky Maytal , Geva Tomer 
Published: October 2024

Expert workers make non-trivial decisions with significant implications. Experts’ decision accuracy is, thus, a fundamental aspect of their judgment quality, key to both management and consumers of experts’ services. Yet, in many important settings, transparency in experts’ decision quality is rarely possible because ground truth data for evaluating the experts’ decisions is costly and available only for a limited set of decisions. Furthermore, different experts typically handle exclusive sets of decisions, and thus, prior solutions that rely on the aggregation of multiple experts’ decisions for the same instance are inapplicable. We first formulate the problem of estimating experts’ decision accuracy in this setting and then develop a machine–learning–based framework to address it. Our method effectively leverages both abundant historical data on workers’ past decisions and scarce decision instances with ground truth labels. Using both semi-synthetic data based on publicly available data sets and purposefully compiled data sets on real workers’ decisions, we conduct extensive empirical evaluations of our method’s performance relative to alternatives. The results show that our approach is superior to existing alternatives across diverse settings, including settings that involve different data domains, experts’ qualities, and amounts of ground truth data. To our knowledge, this paper is the first to posit and address the problem of estimating experts’ decision accuracies from historical data with scarce ground truth, and it is the first to offer comprehensive results for this problem setting, establishing the performances that can be achieved across settings as well as the state-of-the-art performance on which future work can build.

The AI Assessment Scale (AIAS) in action: A pilot implementation of GenAI-supported assessment
Authors: Furze Leon , Perkins Mike , Roe Jasper , MacVaugh Jason 
Published: October 2024

The rapid adoption of generative artificial intelligence (GenAI) technologies in higher education has raised concerns about academic integrity, assessment practices and student learning. Banning or blocking GenAI tools has proven ineffective, and punitive approaches ignore the potential benefits of these technologies. As a result, assessment reform has become a pressing topic in the GenAI era. This paper presents the findings of a pilot study conducted at British University Vietnam exploring the implementation of the Artificial Intelligence Assessment Scale (AIAS), a flexible framework for incorporating GenAI into educational assessments. The AIAS consists of five levels, ranging from “no AI” to “full AI,” enabling educators to design assessments that focus on areas requiring human input and critical thinking. The pilot study results indicate a significant reduction in academic misconduct cases related to GenAI and enhanced student engagement with GenAI technology. The AIAS facilitated a shift in pedagogical practices, with faculty members incorporating GenAI tools into their modules and students producing innovative multimodal submissions. The findings suggest that the AIAS can support the effective integration of GenAI in higher education, promoting academic integrity while leveraging technology’s potential to enhance learning experiences.

Implications for practice or policy:

Higher education institutions should adopt flexible frameworks like the AIAS to guide ethical integration of GenAI into assessment practices.
Educators should design assessments that leverage GenAI capabilities, while supporting critical thinking and human input.
Institutional policies related to GenAI should be developed in consultation with stakeholders and regularly updated to keep pace with technological advancements.
Policymakers should prioritise research funding into the impacts of GenAI on higher education to inform evidence-based practices.
The Nash problem for torus actions of complexity one
Authors: Bourqui David , Langlois Kevin , Mourtada Hussein 
Published: October 2024

Abstract
We solve the equivariant generalized Nash problem for any non-rational normal variety with torus action of complexity one.
Namely, we give an explicit combinatorial description of the Nash order on the set of equivariant divisorial valuations on any such variety.
Using this description, we positively solve the classical Nash problem in this setting, showing that every essential valuation is a Nash valuation.
We also describe terminal valuations and use our results to answer negatively a question of de Fernex and Docampo by constructing examples of Nash valuations which are neither minimal nor terminal, thus illustrating a striking new feature of the class of singularities under consideration.
Sometimes a Ghost is Just a Ghost: Agnes and Spectrality in Henrik Ibsen’s Brand
Authors: D’Amico Giuliano 
Published: October 2024

Abstract
The article focuses on the ghost of Agnes in Henrik Ibsen’s play Brand (1866). Drawing upon different theoretical articulations of the so-called spectral turn, and most notably on Jacques Derrida’s concept of hauntology, the article studies the spectral manifestation of Agnes and how it affects our understanding of Ibsen’s play. Avoiding a metaphorical and/or psychological reading of spectral figures, which sees ghosts as projections of the minds of other characters, the article will concentrate instead on a “proper” or “material” ghost and study its spectrality. The article will therefore seek to answer the following research questions: what role does this seemingly secondary figure play in Ibsen’s dramatic poem? If one of the characters in Brand is in fact a ghost, what are the consequences for our interpretation of the play? In the course of the analysis, this article will show that these perspectives are especially related to the Christ-like status of the protagonist, Brand, and to Agnes’ agency.
Exploring relationships between L1 and L2 writing strategy use and integrated writing performance: A cross-linguistic perspective
Authors: Zhu Xinhua , Yao Yuan , Liao Xian , Xu Wandong , Zhao Pengfei , Jiang Yue 
Published: October 2024

Abstract
The ability to produce a well-written text in English using multiple material resources, such as integrated writing (IW), is widely recognised as a crucial literacy skill for tertiary students. While previous researchers have extensively examined the factors contributing to second language (L2) English integrated writing, the impact of students’ first-language (L1) Chinese writing strategic knowledge and skills on L2 writing performance has received limited empirical attention. Therefore, this study aimed to investigate the simultaneous relationship between L1 and L2 writing strategy use, L1 writing skills, and L2 IW performance among 239 Chinese university students. Results from structural equation modelling revealed that L1 IW strategy use could predict L2 IW strategy use. Furthermore, the use of L1 IW strategies indirectly predicted L2 IW performance through the use of L2 IW strategies. This study contributes to the existing literature by extending research on cross-language effects in the IW context. Additionally, based on the findings, pedagogical implications for teaching IW across two languages are proposed.
