Published: May 2022

Purpose. Development of a torque measuring unit as part of a laboratory complex for studying the energy characteristics of electric drives for the purpose of mathematical modeling of the dynamic operating modes of an electric vehicle drive.
Research methods. Physical experiment, regression analysis, interpolation.
Findings. A torque measuring unit has been developed as part of a laboratory complex for studying the energy characteristics of electric vehicle drives, the design of which allows creating a torque on the shaft of the engine under study using a load and measuring it with a strain gauge force sensor. The laboratory stand together with the developed torque measuring unit corresponds to the required range and measurement accuracy. The experimental data obtained at the test bench make it possible to determine the dependence of the energy consumed by the drive on the mechanical power on the shaft of the engine under study, which makes it possible to analytically describe the drive under study and carry out mathematical modeling in the context of studying the influence of mechanical parameters on the consumed energy in dynamic modes of operation.
Originality. A method for measuring torque on the motor shaft for studying the energy characteristics of electric vehicle drives has been developed. This method is based on the contact method of measurement, which uses 2 motors (loading and testing) and strain gauge force sensor and differs from others in the design that creates a moment on the shaft of the test motor.The result of processing the experimental data obtained by this method is the analytical dependence of the energy consumed by the drive on the value of the mechanical power on the shaft, the parameters of which are the angular speed and torque of the engine. The specified energy characteristic of the drive makes it possible, by means of mathematical modeling, to determine the electromechanical parameters of the drive, minimizing its energy consumption in dynamic modes of operation.
Practical value. A method for measuring the moment on the motor shaft is proposed, with the help of which the dependence of the energy consumed by the drive on the mechanical power on the motor shaft is determined in an analytical form, which allows by mathematical modeling to find the electromechanical parameters of the system that increase the energy efficiency of the drive of an electric vehicle.

Authors:   University of Sheffield, Sanger Sally , Bath Peter A. ,   University of Sheffield, Bates Jo ,   University of Sheffield
Published: May 2022

Online support groups for people with health issues are important digital sources of information for their users, and this includes alcohol online support groups (AOSGs) which provide help to problem drinkers. It is vital that these groups are sustainable as otherwise their usefulness and contribution to patient self-care and wellbeing is limited. The aim of the study drawn upon in this paper was to explore the impact of AOSGs’ discussion forums on users’ beliefs about problem drinking. The study involved semi-structured interviews with twenty-five users of online support groups for people who do not follow the 12-step programme for recovery of Alcoholics Anonymous. This paper focuses on users’ perspectives on sustainability, and the findings suggest that the general approach of the group to recovery and its social dynamics are especially important. It provides a useful contribution to the literature in offering a rare insight into the voices of users of non-12-step groups.

Published: May 2022

Arsenic pollution in groundwater is serious in many areas of the world. The interaction between arsenic, iron and organic matter has an important impact on the transformation and transportation of arsenic in groundwater. This review summarises work in three areas – namely, (a) interaction between different types of organic matter and arsenic, which forms arsenic–organic matter complexes through ligand exchange; (b) oxidation–reduction reaction of organic matter and iron-containing minerals and the formation of complexes between organic matter and iron ions; and (c) formation of ternary complexes of organic matter, arsenic and iron-containing minerals (connected by iron ion bridges) and their characterisation methods. This review has great theoretical and applied value for the discovery of the mechanism of arsenic pollution and the development of arsenic pollution control measures.
Numerical investigation of hydrolysis failure of aggregates in loess
Authors: Sun Jianqiang , Li Xi-An , Gao Rongrong , Ren Yongbiao , Lu Tuo , Pang Tao
Published: May 2022

Large numbers of aggregates in loess are vital components of the skeletal structure of loess. In this study, a simulation of the water stability of aggregates using coupled computational fluid dynamics and the discrete-element method (CFD–DEM) is presented. For the simulation, the ‘fixed coarse-grid’ method of the Particle Flow Code in 3 Dimensions (PFC3D) software program was employed to simulate the particle–fluid coupling. With respect to the degradation law, a customised code was developed using Python, which transformed through the CFD–DEM model the hydrolysis of cement into the degradation process for the bond strength between particles. Under the action of different hydraulic gradients, the rate of hydrolysis of the aggregates increased rapidly with an increase in water pressure, and many piles of particles were denuded from the aggregates, thus causing the destruction of the aggregates. At the same time and under the same water pressure, the rate of hydrolysis of the multi-aggregates was always lower than that of the single aggregate. Also, the density and porosity of the aggregates would affect, to varying degrees, the water stability.
A feasibility study of municipal solid waste leachate utilisation in concrete
Authors: Esmaeili Negar , Heidarzadeh Nima
Published: May 2022

Water was replaced with raw municipal solid waste leachate in a concrete mix. Compared with the control specimen (prepared with freshwater), the hardened concrete specimen made with 100% leachate and cured in freshwater for 28 days showed reductions of 20% in ultrasonic pulse velocity and 45% in unconfined compressive strength. Scanning electron microscopy revealed that an increase in leachate content increased the microscopic pores and cracks within concrete owing to organic matter in the leachate. Heavy metals are contaminants in leachate and can leak from leachate-produced concrete. The toxicity characteristic leaching procedure revealed that the heavy metal leakage of the 100% leachate specimen was lower than the maximum permissible range. Furthermore, the use of leachate in fresh cement paste induced a 56 min delay in initial setting compared with the control specimen. Slump measurements performed 0, 30 and 60 min after concrete fabrication indicated that leachate addition could double the concrete slump as compared with the control specimen. This research provides basic information for the use of raw leachate in concrete mixes. Fresh and hardened concrete properties decreased with an increase in the percentage of leachate in the mix design. Replacement of tap water with 10% leachate satisfied the US standard for ready-mixed concrete. Further investigations are recommended to approve the use of leachate as a part of concrete mixing water.

Movilidad y género en contextos de vulnerabilidad: el caso del Sistema Metropolitano de Tucumán
Authors: González-Alvo Inés , Czytajlo Natalia
Published: May 2022

En este artículo se aborda el concepto de movilidad urbana y las desigualdades socioterritoriales asociadas a ella. A partir de un caso, el del Sistema Metropolitano de Tucumán, se analiza la movilidad cotidiana en contextos de vulnerabilidad desde un enfoque teórico-metodológico, para lo cual se emplean técnicas e instrumentos cuanti-cualitativos. Se caracterizan las estructuras de oportunidad (transporte público e infraestructura de cuidados), los activos de los hogares (planes sociales, vehículos y licencias de conducir) y las prácticas de movilidad (tasa de generación de viajes y los modos de viaje). Como insumo cuantitativo se utilizan las bases de datos de la Encuesta Origen y Destino para Tucumán (2012) y como fuente para el análisis cualitativo se realizan entrevistas en un barrio representativo de la alta vulnerabilidad en la ciudad. Este abordaje permite una lectura desde la interseccionalidad en tanto implica el análisis desagregado del nivel socioeconómico y el género. Del análisis de la movilidad en relación con las esferas productivas y reproductivas se desprenden reflexiones asociadas al concepto de “movilidad del cuidado”. Finalmente, tras aplicarse la perspectiva interseccional, los resultados evidencian patrones diferenciales según el género y una alta vulnerabilidad en la movilidad de las mujeres. Este texto constituye un aporte sobre la inclusión de la perspectiva de género en la agenda de las políticas públicas vinculadas a la movilidad.

Published: May 2022

Nile tilapia (Oreochromis niloticus) are herbivores with longer coiled intestines compared to carnivores; mouth characteristics necessary for plant shredding. Hence, several studies have been conducted to replace feed ingredients in the diet of Nile tilapia considering the increasing cost. In this study, Water spinach (Ipomoea aquatica) was evaluated as a potential feed ingredient for Nile tilapia. A six months feeding trial was conducted to assess the effects of water spinach fish feed composition on the performance of Nile tilapia fingerlings. Five diets were formulated containing 0% (control diet), 5%, 10%, 15% and 20% water spinach composition. Each treatment was carried out in triplicate using 30 Nile tilapia juveniles per replicate with an initial mean weight of 2±1g. The fish were fed at 5% body weight twice per day. Water quality monitoring was done every morning before feeding. There was no significant (p > 0.05) variation in water quality parameters between all the treatments. The best growth performance was recorded from a fish-fed 5% diet (180.49±0.83 g), while fish fed with a 20% diet had poor growth performance (128.98± 0.80g). The highest SGR was obtained in fish fed with a 5% diet (1.34±0.05) while the lowest was obtained in fish fed with a 20% diet (1.09±0.05). Except for SGR, WG, FL, and FW, there was no significant difference (P>0.05) in other growth parameters of all the treatments. Final weight had a significant difference as determined by One-Way ANOVA (F (4,316) =6.363, P=0.00) between 15% and 20% water spinach composition compared to 5% water spinach composition. Therefore, 5% water spinach composition had the best growth performance.

Topographic Response to Simulated Mw 6.5–7.0 Earthquakes on the Seattle Fault
Authors: Stone Ian , Wirth Erin A. , Frankel Arthur D.
Published: May 2022

We explore the response of ground motions to topography during large crustal fault earthquakes by simulating several magnitude 6.5–7.0 rupture scenarios on the Seattle fault, Washington State. Kinematic simulations are run using a 3D spectral element code and a detailed seismic velocity model for the Puget Sound region. This model includes realistic surface topography and a near-surface low-velocity layer; a mesh spacing of ∼30 m at the surface allows modeling of ground motions up to 3 Hz. We simulate 20 earthquake scenarios using different slip distributions and hypocenter locations on a planar fault surface. Results indicate that average ground motions in simulations with and without topography are similar. However, shaking amplification is common at topographic highs, and more than a quarter of all sites experience short-period (≤2 s) ground-motion amplification greater than 25%–35%, compared with models without topography. Comparisons of peak ground velocity at the top and bottom of topographic features demonstrate that amplification is sensitive to period, with the greatest amplifications typically manifesting near a topographic feature’s estimated resonance frequency and along azimuths perpendicular to its primary axis of elongation. However, interevent variability in topographic response can be significant, particularly at shorter periods (<1 s). We do not observe a clear relationship between source centroid-to-site azimuths and the strength of topographic amplification. Overall, our results suggest that although topographic resonance does influence the average ground motions, other processes (e.g., localized focusing and scattering) also play a significant role in determining topographic response. However, the amount of consistent, significant amplification due to topography suggests that topographic effects should likely be considered in some capacity during seismic hazard studies.

Published: May 2022

Background: Assessment of efficacy and safety of daclatasvir+sofosbuvir+ribavirin (DCV+ SOF+ RBV) for 12 weeks as compare to daclatasvir and sofusbuvir for 24 weeks in decompensated cirrhotic patients due to hepatitis C virus (HCV) genotype 3 infection.Methods: An observational, prospective, COHORT study over 1 year, in decompensated cirrhosis due to G3-HCV infected adult patients. Treatment was a combination of sofosbuvir 400 mg/day+daclatasvir 60 mg/day, with or without a weight-adjusted dosing of ribavirin for 12 or 24 weeks. The primary efficacy endpoint was sustained virologic response rates 12 weeks after therapy (SVR 12). The primary safety endpoint was treatment withdrawal rates secondary to severe adverse events.Results: The 32 patients were screened and 2 were excluded, one patient due to associated HBV+, one patient due to severe anemia. 30 patients were randomized. All 30 randomized patients were divided into two groups. Group 1 was given SOF+DCV+RBV for 12 weeks while group 2 patients were given SOF+DCV for 24 weeks. 81.8% of the participants in the group1 achieved SVR 12. The 90.9% of the participants in the group 2 achieved SVR12 (p=1). No other patient or treatment basal variables influenced the treatment effectiveness. No patient treatment withdrawal secondary to severe adverse events was observed.Conclusions: Both the regimen SOF+DCV with or without RBV are highly efficacious and safe. Addition of RBV can reduce the treatment duration to 12 weeks, and it will further improve compliance and more convenient for the patients.

The collection of material was carried out in the Voronezh Reserve and on the rookeries of marine mammals on the Commander Islands (Bering Island, Medny Island). To fix the material, Shteve, Bouin, and Zenker liquids were used. Paraffin sections were stained with hematoxylin and eosin, aldehyde fuchsin according to Helmi–Dyban. The linear dimensions of cell structures were measured, the cross-sectional area of cells and their nuclei was calculated, and the nuclear cytoplasmic index was calculated. The numerical density of somatotropic endocrinocytes in the field of view was determined. For electron microscopy, pituitary specimens were fixed in 2.5% glutaraldehyde and 1% osmium fixative. Sections were prepared on BS-490 and LKB-4800 ultramicrotomes. Sections were counterstained with uranyl acetate and lead citrate and studied under a Tesla BS-500 electron microscope.

Results. In river beavers and sea otters at the age of 6 months, compared with newborn animals, the number of somatotropic cells in the center of the pituitary gland increases by 3.46 (p<0.05) and 3.32 times (p<0.05), respectively, and in the lateral zones – 2.61 times (p<0.05) and 3.39 times (p<0.05); cell cytoplasm area – 1.96 times (p<0.05) and 1.85 times (p<0.05); the area of the nuclei – 1.48 times (p<0.05) and 1.30 times (p<0.05). In river beavers and sea otters at the age of one year, compared with six-month-old animals, an increase in the number of somatotropic cells in the center of the pituitary gland by 1.27 times (p<0.05) and 1.33 times (p<0.05) was revealed; and in the lateral zones by 1.08 times (p<0.05) and 1.02 times (p>0.05); and area of the cytoplasm of cells, respectively – 1.29 times (p<0.05) and. 1.25 times (p<0.05). The maximum indicators of secretory activity of somatotropic cells were found in river beavers and sea otters at the age of 1 year.

​Impact of Policy Change on Technical Efficiency: Evidence from Small Scale Food Crop Farmers in Kellem Wollega, Ethiopia
Authors: Terefe Melkamu Kena
Published: May 2022

Background: An effort was made by the Ethiopian government to increase the level of technical efficiency of farmers across the country. However, due to climate change, smallholder farmers were facing challenges to increase technical efficiency in crop production. Adaptation to climate change is crucial to uphold and increase food crop productivity. This study analysis the impact of climate change adaptation and policy issues on food crop production efficiency in Kellem Wollega, Ethiopia. Methods: The data was gathered from 400 randomly selected food crop smallholder farmers. The Cobb-Douglas production function was used by including the climate change adaptation measures as explanatory variables in technical inefficiency. Simulation was made to adaption measures that can be influenced by the policy variables to see their impact on the level of technical efficiency. Result: The finding show that the use of adaptive practices (multiple crop type, improved crop varieties, adjusting planting dates and irrigation) had a significant and positive effect on technical efficiency whereas land fragmentation reduces efficiency level. Regarding simulation of policy variables the result show that the mean technical efficiency would increase with rising level of improved crop varieties, adjusting planting dates and irrigation practices. The results of the simulation of land fragmentation climate change adaptation variables show that the mean technical efficiency declines as a result of land fragmentation. Empirical results reveal that with appropriate policy intervention (climate change adaptation measures) the technical efficiency level of food crop farmers can be enhanced.

Authors: . Sunil , Loura Deepak , . Harender , Dhankar Amit , . Akshit , Kumar Sushil
Published: May 2022

Wheat is India’s second-largest staple food crop grown in different agro climatic zones within different crop sequences, as a result of which a diversity of weeds infests to this crop. Diversity of weeds including grassy, broadleaf weeds and sedges are mainly infested to the crop. Phalaris minor (grassy) and Rumex dentatus (broadleaf) are the most dominant weeds in northern region of country. For receiving fast results, use of herbicides is most popular method of weed control and used all over the world. But over reliance on herbicides has created several complications such as environmental quality deterioration, shifting in weed flora and development of herbicide resistant weeds. These problems can be abridged to a great extent by decreasing reliance on chemical method which can be done by integration of various cultural and mechanical methods to the weed management program. Various cultural practices such as nutrient management, seeding rate, spacing, cropping sequence, water management, sowing methods, sowing time and competitive varieties should be followed in such a way that crop plants utilize much more resources in comparison to weed plants. As a mechanical measure, furrow irrigated raised bed (FIRB) method and stale seed bed technique are recommended for effective weed management. Timely application of herbicides with recommended doses with the help of efficient spray technology improves the efficacy of herbicides. So with the help of integrated weed management (IWM) i.e integration of various cultural, mechanical and chemical methods, we can efficiently managed the diverse weed flora in wheat crop.

Camelina sativa- an oil seed flowering plant that originated in North Europe and Central Asia is known by many names: gold-of-pleasure, false flax, wild flax and German sesame. Belongs to the Family Cruciferae, genus Camelina and it includes several species. Camelina has several favorable agronomic characteristics, it can be cultivated both in winter and spring season, having a remarkable capacity to adapt and resist to difficult climate conditions and pests. Camelina sativa contains 30-48% oil and 33-47% protein and adequate micronutrients with unique properties for industrial and nutritional applications. In addition, Camelina is a promising oilseed crop for production of edible oil, seed meal for animal feed rations and/or biodiesel feedstock. The high amounts of unsaturated fatty acids (about 90%) make camelina oil fast-drying which can be used for making polymers, varnishes, paints, cosmetics and dermatological products. Camelina sativa seed meal consisting of up to 50% crude protein- can be sold asan ingredient for cattle and chicken feed, adding further value to producing camelina. Overall, Camelina oil, due to its composition, has multiple uses in various industries: feed technology, biodiesel production, biopolymer industry, cosmetic industry (skin-conditioning agent), in food products due to its high omega-3 fatty acid content and low erucic acid content and as milk fat substitution.

Authors: Xu Ping , Li Yan , Li Chenjun , Zheng Weiyin , Li Hao , Shen Lu , Yang Shuyong
Published: May 2022

Background: MicroRNA-143 (miR-143) has been reported that its biological function is to serve as a target to inhibit tumor progression in human oral squamous cell carcinoma (OSCC). However, its role and molecular mechanisms in tongue squamous cell carcinoma (TSCC) were still unknown. Methods: Several in vitro experiments were performed using CAL-27 cells, including cell proliferation experiment, wound healing experiment, flow cytometry, transwell and colony formation experiments. In addition, we also performed in vivo experiments to study the potential application of miR-143 in tumorigenesis of TSCC. Result: The result exhibited that miR-143 up-regulation could significantly suppress proliferation, migration and invasion ability of CAL-27 cells and make these cells stop at G0/G1 phase. We reported that upregulation of miR-143 would suppress its tumorigenic ability. Moreover, we also found that the overexpression of miR-143 would reduce the phosphorylation level of STAT3, p65 and AKT. In addition, miR-143 overexpression decreases CDK2 expression while as expression level of E-cadherin was increased.
Histoire des femmes et du genre : Pénélope aussi a une histoire!

Published: May 2022

Pénélope, Nausicaa, Ariane, Sappho, Aspasie, Olympias, autant de noms de figures féminines connues qui ont longtemps servi de décor à l’histoire des Grecs sans que l’on s’interroge vraiment sur leur propre histoire. Qu’en est-il aujourd’hui ? Pour répondre je propose de suivre mon expérience, celle d’une enseignante-chercheuse à l’université en France depuis les années 1970. Cette contribution construite à partir d’un trajet personnel ne prétend pas être une synthèse sur l’enseignement et la recherche sur l’histoire des femmes et du genre en histoire ancienne, mais seulement un éclairage parmi d’autres. Elle décrit le passage d’une histoire des femmes à une histoire du genre, puis à une histoire mixte qui se développe aujourd’hui en histoire des mondes antiques, grecs et romains.

Over the last century language teaching methods have undergone fundamental changes. A different set of approaches has appeared in response to the ineffectiveness of traditional teaching methods. As traditional approaches are not designed to pursue students’ interests and do not encourage them to cooperate in self-directed learning, there is an urgent need to develop more effective teaching and learning approaches for 21st-century learners. Nowadays, teacher-centered education gives the way to more student-centered approaches, where the main goal of learning is to nourish interest in students and give them an opportunity to inquire and master learning in a more meaningful way. As technology-assisted education has become an indispensable and challenging part of student-centered education, it has become absolutely vital for teachers to enhance the integration of technology into their classrooms. Inquiry-based English language teaching through digital applications is among the most contemporary teaching approaches, which perfectly corresponds to the 21st-century demands while enhancing autonomy and fostering students’ reading interest. Considering the urgency of integrating contemporary teaching methods in English as a Foreign Language (EFL) class, the objective of the presented study has been shaped to outline the impact of inquiry-based English language teaching through digital applications on primary learners’ autonomy and interest development in one of the Georgian private schools. A quantitative method was applied to the present study in order to compare pre and post-experimental questionnaire results and measure primary schoolchildren’s autonomy level, curiosity, and interest in reading through digital applications before and after the experiment. The learning processes of the experimental and control groups were compared. The obtained data has been analyzed using SPSS to compare the survey results. The quantitative study has revealed that the 21st-century generation positively responds to contemporary teaching methods and inquiry-based teaching through digital applications has proved to be effective. Based on the research findings, eBooks and digital applications are reasonable resources to be utilized in EFL reading lessons as learning only with the help of traditional books appears to be boring for students. Based on the study results, it is obvious that working on electronic texts through inquiry-based approaches has assisted students in completely changing their negative attitudes toward reading and increased engagement and autonomy. Consequently, because of the decreasing interest in reading through traditional books, there is a need of promoting more student-centered teaching practices and increase technology integration in the teaching and learning process.

L’étiquetage est une pratique comportant des relents psychologiques qui consiste à référer une personne à une image parfois dévalorisante d’elle. Il est courant et visible dans les relations entre les parents et leurs enfants derrière un langage verbal dévalorisant, des insultes amoindrissantes, des sanctions ou des tâches en fonction des représentations. L'objectif de cette recherche était de contribuer à une meilleure compréhension de l'étiquetage et de son impact sur le processus d'identification des jeunes délinquants. Nous avons recruté trois détenus mineurs (âgés entre 16 à 18 ans) de la prison centrale de Bamenda au Cameroun et mené des entretiens semi-directifs. Les analyses de contenu des entretiens ont indiqué que l’étiquetage a conduit à l’acceptation de la référence à l'étiquette, une auto-valorisation de l’étiquette et plus loin la défense du parent qui étiquète. Les résultats de cette étude pourraient permettre la prise de conscience des effets de l’étiquetage sur le développement de l’enfant en Afrique sub-saharienne ainsi que le développement des stratégies d'intervention et une meilleure prise en charge des jeunes délinquants placés en institutions pénitentiaires. 

 

Labeling is a practice with psychological overtones that involves referring a person to a sometimes degrading image of him or herself. It is common and visible in the relationships between parents and their children behind devalorising verbal language, insults, sanctions or tasks depending on the representations. The purpose of this research was to contribute to a better understanding of labeling and its impact on the identification process of young offenders. We recruited three juvenile inmates (ages 16-18) from the Bamenda Central Prison in Cameroon and conducted semi-structured interviews. Content analyses of the interviews indicated that labeling led to acceptance of reference to the label, a self-valorisation of the label, and further the defense of the labeling parent. The results of this study could help to raise awareness of the effects of labelling on child development in sub-Saharan Africa, as well as the development of intervention strategies and better care for young offenders incarcerated in prisons.

In recent years, the auditor reporting model suffered several relevant modifications, one being related to the communication of Key Audit Matters (KAMs). By better understanding what factors can affect the number of disclosed items, the users of the audit report can gain more trust in the work performed by the auditors. The measurement of the number of KAMs contributes to the overall understanding of the company’s risk level as they provide financial statement users with relevant information about significant estimates and risks reported in the financial statements. The paper aims to determine the variables from quantitative empirical studies influencing the number of disclosed Key Audit Matters in the auditor’s independent report by conducting a structured literature review of the relevant academic research papers. Our findings reveal that factors such as audit committee characteristics and financial expertise, auditor and client general characteristics and accounting aspects, gender of the audit partner, the measurement uncertainty together with the country of the audited company and audit market structure, all have an impact on the number of disclosed KAMs.

Levels of credit risk or credit quality, which can be measured by the ratio of non-performing loans (NPL), can be seen as a form of representation in companies, particularly in the banking sector. The purpose of this study is to determine the impact of Sustainability Report disclosure, specifically in each dimension of economic, environmental, and social disclosure, on the credit risk level of each banking company in Indonesia, Singapore, and Malaysia, as measured by the NPL ratio. The effect of Sustainability Reporting disclosure on NPL is consistent with the use of stakeholder, legitimacy, and signalling theories, where the three theories are related and explain to each other that a company does not only function for its own benefit, but also for other stakeholders. This study collected 129 samples from banking sector companies in Indonesia, Singapore, and Malaysia over a three-year period, from 2018 to 2020, using the purposive sampling method. Multiple linear regression was also utilized to evaluate and determine the impact of each component of the Sustainability Report disclosure on the NPL ratio, as well as other control variables. According to the study's findings, the overall disclosure of the Sustainability Report has a significant influence on the NPL ratio in Indonesian and Singaporean banking sector companies, but not in Malaysian companies. Although partially, economic disclosure has a negative and significant impact on NPL in Singapore, whereas environmental disclosure only has an impact on the NPL ratio in Malaysia, and the final factor is the impact of social disclosure, which has a negative and significant impact on NPL in Indonesia.
