Efficiency analysis in bi-level on fuzzy input and output

To enhance the conventional framework of data envelope analysis (DEA), a novel hybrid bi-level model is proposed, integrating fuzzy logic with triangular fuzzy numbers to effectively address data uncertainty. This model innovatively departs from the traditional DEA’s ’black box’ approach by incorporating inter-organizational relationships and the internal dynamics of decision-making units (DMUs). Utilizing a modified Russell’s method, it provides a nuanced efficiency analysis in scenarios of ambiguous data. The study aims to enhance the accuracy and applicability of Data Envelopment Analysis in uncertain data environments. To achieve this, a novel hybrid bi-level model integrating fuzzy logic is presented. Validated through a case study involving 15 branches of a private Iranian bank, the model demonstrates improved accuracy in efficiency assessments and paves the way for future research in operational systems uncertainty management. The results indicated that, among the 15 branches of a private Iranian bank analyzed for the year 2022, branches 1, 10, and 11 demonstrated leader-level efficiency, while branch 3 exhibited follower-level efficiency, and branch 1 achieved overall efficiency. These branches attained an efficiency rating of E++, signifying a high level of efficiency within the model’s parameters.

Effect of Vocal Function Exercises on the Voice Handicap Index, Vocal Fatigue Index, and Number of Vocal Fatigue Symptoms in Bank Workers: Single-Blinded Randomized Controlled Trial.

Vocal fatigue (VF) is a significant portion of occupational voice disorders. Researchers have proposed numerous therapeutic approaches to alleviate VF. However, the efficacy of vocal function exercises (VFEs) as a safe, effective, and simple method is unclear. The current study aims to investigate the effect of VFEs on occupational-related VF in Iranian bank workers. A single-blinded randomized controlled trial with four-level blocking After screening 444 workers, 43 persons with vocal fatigue (VF) were allocated between intervention and control groups. The gender of participants was considered a confounding parameter. Intervention group participants (IGP) (20 males and two females) practiced vocal function exercises (VFEs) (online training) for two weeks, while control group participants (CGP) (20 males and a female) continued their routine lifestyle. The Number of Vocal Fatigue Symptoms (NoVFS), Maximum Phonation Time (MPT), Voice Handicap Index (VHI), and Vocal Fatigue Index (VFI) at pre-intervention and post-intervention levels were gathered and compared. According to the intergroup, pre-/post-intervention differences, and intragroup analysis, the IGP experienced a significant reduction in the NoVFS (P = 0.006, P = 0.009), the mean score VHI (P:0.006, P: 0.001, P: 0.001), the total mean score of VFI (P < 0.001, P < 0.001, P < 0.001), and the first (P = 0.005, P = 0.002, P < 0.001) and second (P = 0.006, P < 0.001) factors' mean score of VFI. Additionally, there was an improvement in the MPT (P < 0.001, P < 0.001, P < 0.001) and the third factor (P = 0.01, P = 0.004, P = 0.021) mean score of VFI. Vocal function exercises can alleviate symptoms, voice handicaps, tiredness, avoidance, and physical discomfort of vocal fatigue in bank workers. Additionally, it can improve glottal (pulmonary) sufficiency and rest recovery of vocal fatigue in this group of workers.

A firm-specific Malmquist productivity index model for stochastic data envelopment analysis: an application to commercial banks

In the data envelopment analysis (DEA) literature, productivity change captured by the Malmquist productivity index, especially in terms of a deterministic environment and stochastic variability in inputs and outputs, has been somewhat ignored. Therefore, this study developed a firm-specific, DEA-based Malmquist index model to examine the efficiency and productivity change of banks in a stochastic environment. First, in order to estimate bank-specific efficiency, we employed a two-stage double bootstrap DEA procedure. Specifically, in the first stage, the technical efficiency scores of banks were calculated by the classic DEA model, while in the second stage, the double bootstrap DEA model was applied to determine the effect of the contextual variables on bank efficiency. Second, we applied a two-stage procedure for measuring productivity change in which the first stage included the estimation of stochastic technical efficiency and the second stage included the regression of the estimated efficiency scores on a set of explanatory variables that influence relative performance. Finally, an empirical investigation of the Iranian banking sector, consisting of 120 bank-year observations of 15 banks from 2014 to 2021, was performed to measure their efficiency and productivity change. Based on the findings, the explanatory variables (i.e., the nonperforming loan ratio and the number of branches) indicated an inverse relationship with stochastic technical efficiency and productivity change. The implication of the findings is that, in order to improve the efficiency and productivity of banks, it is important to optimize these factors.

Essential oil variation of Achillea filipendulina populations in farm condition

ABSTRACT Achillea filipendulina is a native aromatic plant with antibacterial and anti-inflammatory properties. This research aimed to determine and compare the essential oil content and composition of different populations of this plant in farm condition. Seeds provided by the Natural Resources Gene Bank of Iran were sown in a field experiment over two years. Essential oils from the aerial parts of all populations, at full flowering stage, were obtained by hydro-distillation and analysed by gas chromatography (GC) and gas chromatography-mass spectrometry (GC/MS). The oil yields ranged from 0.13% to 1.20%. Twenty-six compounds were identified with 1,8-cineole (2.0–73.5%), santolina alcohol (14.2–35%) and borneol (0.6–20.4%) as major components. Cluster analysis divided all accessions into two clusters. The main compounds in cluster 1 (two populations) were santolina alcohol, borneol, cis-chrysanthenyl acetate, bornyl acetate and α-pinene. The oils in Cluster 2 contained borneol, cis-chrysanthenyl acetate and high amount of 1,8-cineole (22.6–73.5%) as main components.

Extending Intention to Use Electronic Services Based on the Human–Technology Interaction Approach and Social Cognition Theory: Emerging Market Case

After several years of providing extensive e-banking services, customers' acceptance and use of e-banking systems are major competitive advantages for banks and other IT-based institutions. Reports are indicated, a wide range of people is reluctant to use e-banking services effectively. Accordingly, this research aims to improve users&#x2019; attitudes and intentions to use e-banking in a transition economy. To achieve this aim, the social cognition theory is employed within the framework of human&#x2013;technology interaction as a novel approach to extend the technology acceptance model. To this effect, partial-least-squares structural equation modeling is applied to study survey data of five Iranian banks. The results show that users&#x2019; innovativeness, compatibility, vicarious experience, and flexibility in electronic learning significantly influenced their attitude, but technophobia inversely influenced the intention to use e-banking. Regarding technology aspects, quality of functional structure was the sole factor that significantly influenced intention to use e-banking while the influence of online interactive structure, innovative structure, and security structure on users' intention was not confirmed. We conclude that banks in most transition economies that have similar socioeconomic conditions could influence users&#x2019; attitudes and intentions toward e-banking by drawing from the insights of this study, thus enabling the banks to make more informed choices about investing in Internet banking.

Designing a Model of Professional Ethical Ideals Based on the Dimensions of Organizational Structure and Managers' Thinking Styles in Islamic Banking at the Agricultural Bank of Iran

Objective: The objective of this research is to design a model of professional ethical ideals based on the dimensions of organizational structure and managers' thinking styles in Islamic banking at the Agricultural Bank of Iran. Methodology: This study is classified as applied research in terms of its purpose, and as a descriptive correlational study in terms of data collection methods. The statistical population includes two groups: the first group consists of 50 experts and professors in management and banking and ethics, who hold at least a doctoral degree and were selected through random sampling. The second group includes all senior managers, provincial managers, and top-ranking heads at the Agricultural Bank, totaling 430 individuals. Data analysis was conducted using SPSS23 and AMOS23 software, Pearson correlation coefficients, and structural equation modeling. Findings: The results showed that the direct effect of the exogenous variable of legal thinking style (p &lt; .05, t = 2.11, β = .12), holistic thinking style (p &lt; .05, t = 2.64, β = .13), free-thinking style (p &lt; .05, t = 7.34, β = .57), autocratic thinking style (p &lt; .05, t = 2.532, β = .16), organizational complexity (p &lt; .05, t = 2.65, β = .32), formality (p &lt; .05, t = 5.84, β = .21), and organizational centralization (p &lt; .05, t = 5.99, β = .85) on the variable of professional ethical ideals in Islamic banking is positive and significant. Additionally, the direct effect of the exogenous variable of conservative thinking style on the variable of professional ethical ideals in Islamic banking is negative and significant (p &lt; .05, t = 6.26, β = -.43). Conclusion: Support for and backing of producers and exporters, farmers, industrialists, and others should be a serious concern for banks. Therefore, it is recommended that Islamic banks fully comply with the policies of the Islamic government and the laws and regulations of the central bank, avoiding any form of sectionalism and profit-seeking outside these laws and regulations.

Expression Profiling of ADAMTS (L) Superfamily of Genes in Various Human Eye Tissues.

A disintegrin and metalloproteinase with thrombospondin motifs (ADAMTS) is a superfamily of extracellular proteinases found in both mammals and invertebrates. Although there is some evidence about the role of ADAMTSs in ocular diseases such as glaucoma and ectopia lentis, but there is little information about the expression patterns of ADAMTS-1-20 and ADAMTS-like (ADAMTSL-1-6 and PAPLN) genes in human ocular tissues. This study aimed to evaluate the expression profiling of ADAMTS(L) superfamily of genes in different ocular tissues based on age. In 2019, nine human donated eye globes were provided from the Central Eye Bank of Iran, and were divided into three different groups based on age (under 3 yr old, between 20 to 50 and upper 50 yr old). To assess expression patterns of ADAMTS(L) genes in different ocular tissues including trabecular meshwork, lens, retinal pigment epithelium, macula, and optic nerve in the three age groups, total RNA was extracted from the tissues and reverse transcription polymerase chain reaction followed by Real-time PCR was performed. We demonstrated not only each member of ADAMTS(L) superfamily shows different expression pattern between the five investigated ocular tissues, but also some members have differential expressions among the investigated age groups in same tissues. Differential expression of ADAMTS(L) genes in ocular tissues from different age groups could explain some functional aspects of the tissues and also may be used as prognostic and diagnostic biomarkers for ocular diseases and pathologies. Further studies are required to explore their functional roles associated with ocular pathologies.

Thickness Profile of Donated Corneas Preserved in Optisol-GS versus Sinasol: An Ex-vivo Study.

This study aimed to compare the thickness profile and the endothelial cell density (ECD) of donated corneas maintained in Optisol-GS with those preserved in Sinasol over seven days. Twenty paired donor corneas were received from the Central Eye Bank of Iran. After recording the osmolarity of each medium, one of each of the cornea pairs was preserved in either Optisol-GS or Sinasol media. Then, slit-lamp biomicroscopy and specular microscopic examinations were performed at the baseline and on day seven. Visante optical coherence tomography (V-OCT) was also performed at 1 hour (h), 24h, 72h, and one week post-preservation. The specular microscopic and V-OCT values were then compared between the two groups. The mean osmolarity of the Sinasol group was significantly less than the Optisol-GS group (296 vs. 366 mOsm/L, = 0.0008). The mean central corneal thickness at the measurement points was comparable between the two groups. However, the increase of thickness one week post-preservation in the Sinasol group was remarkably lower than those in the Optisol-GS group ( = 0.027). The mean ECD was comparable between the groups at the baseline and on day seven. However, the mean change of ECD from baseline to day seven was considerably higher in the Optisol-GS group than in the Sinasol group ( = 0.019). Corneal storage in Sinasol over seven days provides better and superior maintenance and preservation of corneal tissue deturgescence and a lower rate of ECD loss over Optisol-GS.

Donor Risk Factors and Environmental Conditions Associated With Poor-Quality Corneas: An Analysis of the Central Eye Bank of Iran (2018-2021).

The purpose of this study was to investigate the donor risk factors and environmental conditions associated with poor-quality corneas using the database of the Central Eye Bank of Iran over 4 years. This cohort study was conducted on the recorded data of all donated corneas at the Central Eye Bank of Iran database from March 2018 to March 2022. Donors' characteristics and tissue variables were extracted from the database. The final corneal quality was determined based on slitlamp biomicroscopic observations and the results of specular microscopy. Environmental variables were also obtained from reliable resources. Risk factors for poor-quality corneas were calculated using logistic mixed-effect regression analysis. All analyses were performed with STATA 17.0. The significance level of 0.05 was considered for all the analyses. The data of 20,625 eyes of 10,601 donors were evaluated. We found that donor age had an inverse correlation with endothelial cell density (r = -0.28, P < 0.001). The trend of donated corneal poor quality decreased between 2018 and 2021. Several factors, including intoxication (odds ratio [OR] = 1.29), obesity (OR = 1.34), diabetes mellitus (OR = 1.63), hypertension (OR = 1.52), and pseudophakic eyes (OR = 1.56), were associated with the poor quality of donated corneal tissues. The outdoor temperature over 26°C was associated with higher odds of poor corneal quality (OR = 1.31), whereas high relative humidity decreased the odds of poor corneal quality (OR = 0.82). This study revealed that the cause of donor death, obesity, donor comorbidities, pseudophakia, and environmental factors could affect the corneal quality and make the donated corneas less suitable for transplantation.

Lessons learned from behaviors of the employees in Iranian banks during the Covid-19 pandemic crisis: A phenomenological study

The aim of this research is to analyze the experiences of employees during the Covid-19 pandemic cri-sis and conceptualize the lessons learned to deal with similar crises in the future. To achieve this, a qualitative approach with a phenomenological strategy was conducted through semi-structured, in-depth interviews with 16 front-line employees of Bank Melli, the largest state bank in Iran. The study found that employee behavior plays a critical role in crisis management, with functional behaviors such as preventive measures, stress management, and sharing valid information being essential. Dysfunctional behaviors such as resistance to change and inconsistent behaviors were also identified. The prevention of infection and stress management were identified as key behaviors to cope with the crisis, while media literacy and acceptance of change were crucial for correct information analysis and crisis management. Overall, the study highlights the challenges faced by employees during the Covid-19 crisis and provides valuable lessons from a behavioral perspective for managers in the banking industry to manage disruptions caused by current and future pandemics. The study emphasizes the importance of learning from the lessons of the Covid-19 crisis to reduce negative effects on physical and mental health.

Frequency and Underlying Causes of Alloimmunization Against Red Blood Cell Antigens in Patients Referred to the Blood Bank of the Tertiary Referral Hospital of Tehran from 2018 to 2020.

Alloimmunization against blood group antigens is an important non-infectious complication of blood transfusion, and early detection of these alloantibodies by antibody screening before transfusion is crucial. Identifying which underlying factors will affect the occurrence of alloimmunization will be necessary to manage this event as accurately as possible. We aimed to assess the prevalence rate and main determinants of RBC alloimmunization among patients referred to a large referral blood bank in Iran. This retrospective cross-sectional study was conducted on all patients referred to a blood bank at Imam Khomeini Hospital between October 2018 and September 2020. Information was collected by referring to the archives of the hospital information system as well as the documents recorded at the blood bank ward and reviewed by two pathologists and completed documents. In total, 39270 cases were cross-matched. Accordingly, the frequency of alloimmunization cases was equal to 220 cases, which indicated a prevalence of 0.56%. The most common alloantibodies were anti-K (43.2%, 95% CI: 36.8‒49.5), anti-E (34%, 95% CI: 27.7‒40.5), and anti-C (16.3%, 95% CI: 11.4‒21.4). Among patients with positive alloimmunization, the most common blood groups were blood group B (34.6%), followed by blood group A (34.1%). Most of these patients were Rh-positive (77.3%). In patients with positive alloimmunization, the frequency of hemoglobinopathy was estimated to be 37.7%. Frequent blood transfusions were found in 42.2%, a history of malignancy in 17.3%, graft history in 11.3%, and a history of pregnancy in 35.0%. Alloimmunization was more prevalent and more predictable among patients with hemoglobinopathies and those receiving recurrent transfusions. Therefore, a history of repeated blood transfusions should be regarded as a risk factor contributing to alloimmunization.

Financial markets, inflation and growth: The impact of monetary policy under different political structures

This study assesses the likely effects of different political structures on economic growth by the effects of interest rate on the linkage between financial markets. For this aim, we chose two developing economies with different governance structures, Iran and Argentina. There is a political structure in Iran influenced by religion, whereas Argentina’s political structure does not deal with religion. We first assess the causality amongst the financial markets of the stock market, bank deposits, and the foreign currency market (CM). Then, the effects of the markets and inflation on economic growth are assessed using Granger-causality tests and Markov-switching models. The results show that there are bidirectional causalities between the financial markets in Iran, and unidirectional causalities in Argentina. The markets affect economic growth in the both countries. For Iran, the monetary policy instrument of interest rate indicates no causalities to the markets, whereas there are strong causalities from interest rate to the markets in Argentina. As a result, Argentinian Central Bank can affect economic growth through the money flow between the markets by freely changing interest rate proportioned with the economic situation. Whereas there is no such a possibility for Iran’s Central Bank. In other words, an active Central bank against the inflation volatility in Argentina versus a passive Central Bank in Iran is one of the consequences of the interest rate repression in a political structure influenced by religion.

Resilient banking: model-based assessment of business continuity policies on commercial banks

PurposeCommercial banks face several risks, including credit, liquidity, operational and disruptive risks. In addition to these risks that are challenging for banks to control and manage, crises and disasters can exert substantially more destructive shocks. These shocks can exacerbate internal risks and cause severe damage to the bank's performance, leading banks to bankruptcy and closure. This study aims to facilitate achieving resilient banking policies through a model-based assessment of business continuity management (BCM) policies.Design/methodology/approachBy applying a system dynamics (SD) methodology, a systemic model that includes a causal structure of the banking business is presented. To build a simulation model, data are collected from a commercial bank in Iran. By presenting the simulation model of the bank's business, the consequences of some given crises on the bank's performance are tested, and the effectiveness of risk and crisis management policies is evaluated. Vensim Personal Learning Edition (PLE) software is used to construct the simulation model.FindingsResults indicate that the current BCM policies do not show appropriate resilience in the face of various crises. Commercial banks cannot create sustainable value for the banks' shareholders despite the possibility of profitability, as the shareholders lack adequate resilience and soundness. These commercial banks do not have the appropriate resilience for the next pandemic after coronavirus disease 2019 (COVID-19). Moreover, the robustness of the current banking business model is very fragile for the banking run crisis.Practical implicationsA forward-looking view of resilient banking can be obtained by combining liquidity coverage, stable funding, capital adequacy and insights from stress tests. Resilient banking requires a balanced combination of robustness, soundness and profitability.Originality/valueThe present study is a combination of bank business management, risk and resilience management and SD simulation. This approach can analyze and simulate the dynamics of bank resilience. Additionally, present of a decision support system (DSS) to analyze and simulate the outcomes of different crisis management policies and solutions is an innovative approach to developing effective and resilient banking policies.
