Nonperforming Loan Disposals Without Resolution

Using proprietary data on nonperforming loan (NPL) transactions in China, we document that banks conceal NPLs in disposal transactions that are supposed to resolve NPLs. In these transactions, banks provide financing and retain the credit risks and debt collection obligations. Transaction prices contradict underlying credit risks: Despite being delinquent for 4.5 years, the median NPL package is sold at face value with zero haircut. The majority of NPL packages are resold at a premium to banks’ non–government-owned borrowers, further supporting the concealment view. Banks under stricter regulation conceal NPLs more and engage in more illicit concealment. NPL-concealing banks increase zombie lending, suggesting that an ineffective resolution exacerbates credit misallocation. Recognizing the hidden NPLs implies the total NPLs in China is two to three times the reported amount. This paper was accepted by Victoria Ivashina, finance. Funding: B.

Bibliometric review on teaching methods with artificial intelligence in education

The purpose of this article is to carry out an analysis of the disclosures made on teaching methods applying artificial intelligence in the Scopus database. The bibliometric review method was used to analyze 349 scientific articles dating from 1978 to 2023. The analysis was carried out using Bibliometrix and VOSviewer software, and the results show that from 2021 onwards there will be a notable increase in publications, with Mobile Information Systems being the journal with the highest production. Among 65 countries identified, China is the country with the highest production and the most productive organization was the Ministry of Education of the People’s Republic of China. No single author stands out for his or her highest scientific output, given that the maximum number of articles published per author is two. However, among the most cited authors is Alimisis, D. and the most co-cited author is Wang, Y. In terms of co-authorship, there is little contribution between authors, while collaboration between countries, China together with Hong Kong, Japan, Malaysia, Mexico, South Korea, Taiwan, Thailand form the most collaborative conglomerate. Cooperation between institutions, the division of computer engineering and the National University of Singapore, show the strongest collaboration. The strongest keywords are “artificial intelligence”, followed by “teaching methods” and “machine learning” and the topics that will be trending from 2021 onwards are “machine learning”, “ChatGPT”, “deep learning”.

Comparative Study of Air–Water and Air–Oil Frictional Pressure Drops in Horizontal Pipe Flow

Experimental data for frictional pressure drop using both air–water and air–oil mixtures are reported, compared and used to evaluate predictive methods. The data were gathered using the 2-inch (54.8 mm) flow loop of the multiphase flow facility at the National University of Singapore. Experiments were carried out over a wide range of flow conditions of superficial liquid and gas velocities that were varied from 0.05 to 1.5 m/s and 2 to 23 m/s, respectively. Pressure drops were measured using pressure transducers and a differential pressure (DP) cell. A hitherto unreported finding was achieved, as the pressure drop in air–oil flow can be lower than that in air–water flow for the higher range of flow conditions. Using flow visualization to explain this phenomenon, it was found that it is related to the higher liquid holdup that occurs in the case of air–oil around the annular flow transition and the resulting interfacial friction. This additional key finding can have applications in flow assurance to improve the efficiency of oil and gas transportation in pipelines. Models and correlations from the open literature were tested against the present data.

Analyzing Emerging Trends in Wireless Implantable Medical Devices (IMDs): A Bibliometric Study

In the present era of advanced medical technology, there has been a significant increase in the utilization of wireless-based implantable medical devices (IMDs) in various biomedical applications, including health diagnosis, monitoring, recording, treatment, and other clinical concerns. It is essential to closely examine the research trends in wireless IMD topics to understand their growth trajectory. This can be achieved through the utilization of bibliometric reviews. While there are numerous experimental studies and survey papers on the topic, there is a dearth of review papers that utilize a bibliometric approach. Therefore, this study aims to conduct a bibliometric analysis to identify emerging research trends in wireless IMDs for biomedical applications for the first time. An analysis was conducted on 1,650 articles retrieved from the Scopus database from its inception until September 2023. The study used tools such as VOS Viewer to measure performance and science map parameters, and Tableau Cloud to visually enhance the analysis process. This research endeavor allowed us to analyze historical trends, influential papers, top journals, institutions, countries, and authors within this field. The top three influential journals in this field are IEEE Transactions on Biomedical Circuits and Systems, IEEE Transactions on Antenna and Propagation, and IEEE access. The National University of Singapore is the most productive institution in terms of overall publications. The United States, China, and India make significant contributions to overall publications. Finally, we also examined the most significant keywords and current research areas within this field.

Technology and physical activity for preventing cognitive and physical decline in older adults: Protocol of a pilot RCT.

Cognitive frailty, defined as having both physical frailty and cognitive impairment that does not satisfy the criteria for Major Neurocognitive Disorder, represents an elevated risk for morbidity. Hence, it is crucial to mitigate such risks. Physical activity interventions have been found effective in protecting against physical frailty and cognitive deterioration. This pilot RCT examines if smartwatches and mobile phone applications can help to increase physical activity, thereby improving physical and cognitive outcomes. Older individuals (n = 60) aged 60 to 85 years old will have their physical activity tracked using a smartwatch. The subjects will be randomized into two arms: one group will receive daily notification prompts if they did not reach the recommended levels of PA; the control group will not receive prompts. Outcome variables of physical activity level, neurocognitive scores, and physical frailty scores will be measured at baseline, T1 (3 months), and T2 (6 months). Sleep quality, levels of motivation, anxiety, and depression will be controlled for in our analyses. We hypothesize that the intervention group will have higher levels of physical activity resulting in improved cognitive and physical outcomes at follow-up. This study was approved by the National University of Singapore's Institutional Review Board on 17 August 2020 (NUS-IRB Ref. No.: H-20-038). Wearable sensors technology could prove useful by facilitating self-management in physical activity interventions. The findings of this study can justify the use of technology in physical activity as a preventive measure against cognitive frailty in older adults. This intervention also complements the rapidly rising use of technology, such as smartphones and wearable health devices, in our lives today. This study has been retrospectively registered on clinicaltrials.gov on 5th January 2021 (NCT Identifier: NCT04692974), after the first participant was recruited.

Human factors for a successful Integrated Design Process in Zero Energy Buildings: leadership, trust, and goal orientation. A case study in Singapore

ABSTRACT The Integrated Design Process is one of the most recommended methods to deliver Zero-Energy Buildings as it brings together all the stakeholders in the early moments of design, allowing performance optimisation and synergies among the different approaches and expertise. The practice of this design process is complex and difficult because it aims to integrate evolving decisions by all parties. It has been widely studied from the perspective of the process itself and its efficacy. However, the human side or how to manage the collaboration of the different stakeholders in the design development for a Zero Energy Building is unknown. To address this research gap this study is focused on the synergies among the consultants and the purpose behind this kind of building. Through the analysis of the design process and eight interviews with the main stakeholders of a Zero Energy Building at the National University of Singapore, three human factors are identified as critical for the success of an Integrated Design Process: client leadership, acting as the engine of the project; trust among the team, acting as the glue during the process, and focus on the goals that sustains the effort and allows the continuity in time. Although the results are limited to a case study, they can serve as a guide for clients and consultants to implement optimised Integrated Design Processes for future Zero Energy Buildings.

Climate Modelling and Analytics for Urban Heat Risks Mitigation and Adaptation

This study highlights the need for climate-sensitive urban planning and design in the face of climate change, with a specific focus on Singapore. Rapid urbanization has led to significant warming trends, increased heat stress, and heightened electricity demand for cooling. The Urban Climate Design Lab (UCDL) at the National University of Singapore employs a multidisciplinary approach, merging urban planning, architecture, and urban climate science. The research introduces GIS-based tools to evaluate the microclimate impact of new developments, replacing time-consuming simulations and wind tunnel experiments. These tools encompass: 1) The Urban Wind Environment Model, assessing urban permeability for natural ventilation; 2) The Fine-Scale Wind Environment Model, providing high-resolution pedestrian-level wind speed data. 3) The Urban Tree-Airflow Model, aiding tree placement and species selection for optimal cooling. 4) The Anthropogenic Heat Dispersion Model, estimating the impact of human-generated heat emissions. These GIS tools are integrated into the open-access UCDL Microclimate Digital Platform, facilitating knowledge transfer and empowering stakeholders in climate-sensitive urban planning. The platform offers various climate models and visualization capabilities to enhance evidence-based decision-making for urban climate sustainability and resilience. In the future, the platform will expand its offerings, becoming a valuable resource for urban planners, engineers, health practitioners, environmental experts, and residents adapting to a changing climate.

Transient Customer Response to Data Breaches of Their Information

Cybersecurity breaches pose a substantial concern in the digital era. We investigate how customers respond to multiple unexpected data breaches of their information in India. Difference-in-differences estimates show that digital payments declined by 9% relative to cash payments immediately after an unexpected data breach in a food delivery platform, but the gap disappeared three months later. Customer entry and exit also exhibit weak, short-lived changes. Additional analyses on bank and online grocery data breaches uncover even weaker effects of data breaches. Our findings imply that the perceived benefits of convenience outweigh the costs of payment security risks. This paper was accepted by David Sraer, finance.

Research Dissemination of Indonesian Institute of Sciences (LIPI) 2017-2020:

Background of the study: Dissemination of the research results of the Indonesian Institute of Sciences (LIPI) in 2017-2020 as measured by the distribution of publications. Purpose: This study aims to determine the bibliometric profile of research results documents owned by the Indonesian Institute of Sciences (LIPI) for 2017-2020 which have been disseminated. Method: The research method used is a quantitative bibliometric method with descriptive statistical analysis, and co-authorship analysis and co-occurrence analysis with VosViewer software. Findings: There are three groups of findings: document distribution, research collaboration, and research trends, it is known that: (1) research documents on Scopus excel in large number, wide scope of various publications, and description about publication status and types of document access; (2) research documents on DOAJ excel in the scope of Indonesian local publications; (3) LIPI’s researcher with the most research results is Sumowodagdo S.; (4) LIPI’s research collaboration is consistent with the University of Indonesia and the National University of Singapore; (5) LIPI’s research trends are consistent in Indonesian studies with Indonesia as the keywords. Conclusion: The domination of the largest number of LIPI’s research documents, collaboration, and keyword is found in research results indexed by the Scopus. Increased research can be done on a list of keywords that appear less frequently. Countries and institutions that have little collaboration also need attention and increase their collaboration. Countries and institutions with frequent collaboration also need to be maintained.

Semantic segmentation of longitudinal thermal images for identification of hot and cool spots in urban areas

This work presents the analysis of semantically segmented, longitudinally, and spatially rich thermal images collected at the neighborhood scale to identify hot and cool spots in urban areas. An infrared observatory was operated over a few months to collect thermal images of different types of buildings on the educational campus of the National University of Singapore. A subset of the thermal image dataset was used to train state-of-the-art deep learning models to segment various urban features such as buildings, vegetation, sky, and roads. It was observed that the U-Net segmentation model with ‘resnet34’ CNN backbone has the highest mIoU score of 0.99 on the test dataset, compared to other models such as DeepLabV3, DeeplabV3+, FPN, and PSPnet. The masks generated using the segmentation models were then used to extract the temperature from thermal images and correct for differences in the emissivity of various urban features. Further, various statistical measures of the temperature extracted using the predicted segmentation masks are shown to closely match the temperature extracted using the ground truth masks. Finally, the masks were used to identify hot and cool spots in the urban feature at various instances of time. This forms one of the very few studies demonstrating the automated analysis of thermal images, which can be of potential use to urban planners for devising mitigation strategies for reducing the urban heat island (UHI) effect, improving building energy efficiency, and maximizing outdoor thermal comfort.

Associations Between Cardiovascular Risk Factors and Arterial Spin Labelling Derived Perfusion Parameters

AbstractBackgroundDecreased cerebral blood flow (CBF) and deterioration of blood‐brain barrier (BBB) are suggested to be precursor conditions of cognitive impairment. Using a novel multi‐echo‐time arterial spin labelling (ASL) protocol, we examined the time of exchange (Tex) of water across the BBB as a measurement of BBB permeability. We further examined the association of cardiovascular risk factors with Tex in an ongoing cohort study.MethodData (n = 29, mean age: 55.9±6.1years, 69% women) were drawn from Neurological biomarkers of Blood, MRI and Cognition (NEURO‐BMC) study performed at National University of Singapore. NEURO‐BMC is an ongoing prospective cohort study (age: 45‐65 years) on brain changes in a subclinical phase of cognitive impairment. A multi‐echo, Hadamard‐encoded multi‐post‐labelling‐delay pseudo‐continuous ASL (PCASL) protocol was used on a 3T scanner. ExploreASL was used with a modified version of FSL FABBER(4) to quantify cerebral blood flow (CBF), arterial transit time (ATT), and Tex. ASL‐extracted parameters were compared with cardiovascular risk parameters such as blood pressure (BP), BMI and smoking status.ResultHigh systolic and diastolic BP were associated with significantly reduced Tex (Fig 1). Additionally, higher systolic and diastolic BP showed a trend of increased ATT and reduced CBF, though the associations were not statistically significant (Table 1). High BMI had a significant association with increased ATT and reduced CBF. However, no trend was observed between BMI and Tex. Participants who ever smoked were observed to have a reduced Tex and CBF and increased ATT, but statistical significance was only found for CBF (Fig 1).ConclusionIn this pilot study, we showed that BBB‐ASL‐derived parameters ‐ ATT, CBF, and Tex ‐ were associated with BP, BMI, and smoking status. While the sample size for this preliminary analysis was too small to make a definitive conclusion as not all associations were statistically significant, all studied cardiovascular risk factors showed their potential in increasing the risk of BBB deterioration. Further investigation with a larger sample size and other health risk factors to assess these observations is warranted.

ENLIGHT: A consensus checklist for reporting laboratory-based studies on the non-visual effects of light in humans

There is no consensus on reporting light characteristics in studies investigating non-visual responses to light. This project aimed to develop a reporting checklist for laboratory-based investigations on the impact of light on non-visual physiology. A four-step modified Delphi process (three questionnaire-based feedback rounds and one face-to-face group discussion) involving international experts was conducted to reach consensus on the items to be included in the checklist. Following the consensus process, the resulting checklist was tested in a pilot phase with independent experts. An initial list of 61 items related to reporting light-based interventions was condensed to a final checklist containing 25 items, based upon consensus among experts (final n=60). Nine items were deemed necessary to report regardless of research question or context. A description of each item is provided in the accompanying Explanation and Elaboration (E&E) document. The independent pilot testing phase led to minor textual clarifications in the checklist and E&E document. The ENLIGHT Checklist is the first consensus-based checklist for documenting and reporting ocular light-based interventions for human studies. The implementation of the checklist will enhance the impact of light-based research by ensuring comprehensive documentation, enhancing reproducibility, and enabling data aggregation across studies.

Association between psychological distress and mental help-seeking intentions in international students of national university of Singapore: a mediation analysis of mental health literacy.

International students encounter a wide range of challenges that can have a significant impact on their mental health. Seeking help is one of the primary means of managing mental health, and more attention is required. This study aimed to investigate the psychological distress(PD), mental health literacy(MHL), and mental help-seeking intentions(MHSI) in international students of National University of Singapore(NUS), to explore the correlation between the three and to verify the mediating role of MHL in PD and MHSI. This cross-sectional study was conducted between May and July 2023 using the Mental Help Seeking Intention Scale(MHSIS), Patient Health Questionnaire-9(PHQ-9), Generalized Anxiety Disorder-7(GAD-7), and Mental Health Literacy Scale(MHLS). 281 international students(177 males, 104 females;) in NUS completed self-report questionnaires. SPSS 25.0 was applied to the data for descriptive analysis, Pearson correlation analysis and stepwise regression analysis. Mediation analysis fully for all potential confounding factors were conducted. Significant correlations were found between PD, MHL and MHSI. MHLS- knowledge of how to seek professional information(MHLS- H) completely mediated the association of anxiety with MHSI[B=-0.271; 95% confidence interval(CI): (-0.067, 0.0037)]; MHLS- attitude that promote recognition or appropriate help-seeking behavior(stigma)(MHLS- H) partially mediated the association of PD with MHSI[B = 0.104, 95% CI: (0.008, 0.179)]; with mediating effects accounting for 100% and 24.847% of the total effect. In addition, demographic variables such as gender, years in Singapore and residence type mediated both the direct and indirect effect of the mediation model. MHL mediated both the direct and indirect effects on the association between PD and MHSI, especially, the mediator of the MHLS- H and MHL-A. It means that MHSI in this population can be improved by increasing MHL and thus the PD. The findings suggest that, such as providing information about how to access to professional services and promoting disorder recognition to the international students, may help them develop their psychological well-being and good mental health care decisions.

Evaluating the internalisation of the intrinsic role of health advocacy of student pharmacists in a new integrated Bachelor of Pharmacy curriculum: a mixed-methods study

To keep up with the contemporary health landscape, there is an imperative need for healthcare professionals to practise health advocacy through health promotion on the individual, population, and systems levels. In the Academic Year of 2020/2021, the National University of Singapore (NUS) Department of Pharmacy implemented a new spiral curriculum integrating basic, clinical, and systems sciences with one of its aims to deepen students’ health advocacy internalisation and prepare them as future health advocates. A mixed-methods approach was adopted. Questionnaires were disseminated across three time-points to elicit students’ levels of internalisation of health advocacy, which were then categorised into levels, and a Mann–Whitney U test was conducted. In comparison with prematriculation, no significant difference was found after students underwent the first year of the curriculum, while a significant difference was found after students underwent two years of the curriculum. Semi-structured interviews were also conducted after each Academic Year to gain deeper insights into the questionnaire results. Thematic analysis of the interviews revealed that curricular integration in the first year was perceived to be lacking. However, with learnt knowledge constantly reinforced and more experiential learning opportunities incorporated throughout the second year, students found the integrated curriculum beneficial in instilling confidence to practise health advocacy. This study offers insights into the prospects of a spiral integrated curriculum in imparting health advocacy, and may even suggest its potential to be applied to other educational settings. Future follow-up studies can also be conducted on the same study population to evaluate long-term impacts and areas for improvement of the curriculum.

In Case You Haven't Heard…

Individuals with Parkinson's disease may be at significantly higher risk for suicidal thinking and behavior than people without the disease, according to a meta‐analysis published last week in JAMA Neurology. “Patients with [Parkinson's disease] possess multiple risk factors for suicidality, such as advanced age, living with a chronic condition, as well as limitations in physical mobility and functional ability,” wrote Aaron Shengting Mai, M.S., of the National University of Singapore; Yinxia Chao, M.D., Ph.D., of the National Neuroscience Institute Singapore; and colleagues. Efforts at early detection and management of suicidality in patients with Parkinson's can help to reduce patients' risk of death and improve their quality of life, they continued. “Patients with [Parkinson's disease] often experience great psychiatric comorbidity, of which the most prominent is depression,” the researchers wrote. “Depressive mood disorders are the greatest risk factors for both suicidal ideation and suicidal behavior and are present in almost half of patients with Parkinson's.”
