Background

The intensity of emergency services is an increasing health problem all over the world, necessitating an effective triage system. The aim of this study was to evaluate the validity and reliability of the “ANKUTRIAGE” in children.

Methods

This prospective, longitudinal study was carried out at a pediatric emergency department. ANKUTRIAGE, a 5-level computer-aided triage decision support system, was developed. Patients younger than 18 years who do not need emergency intervention, who had complete vital sign measurements, who gave consent for the study, and who were admitted to the emergency service during working hours with trained personnel were included. For validity, agreement between the urgency levels determined by ANKUTRIAGE and the reference triage systems: Pediatric Canadian Triage and Acuity Scale and Emergency Severity Index, was evaluated. In addition, the association of urgency levels with clinical outcomes was studied. To assess reliability, patients were evaluated by 2 blinded healthcare professionals using ANKUTRIAGE and a quadratic weighted κ was estimated.

Results

A total of 1232 children with a median age of 4.00 years were included. ANKUTRIAGE acuity levels significantly correlated with the number of resources used, the number of patients undergoing life-saving procedures, pediatric intensive care unit, and overall hospitalization rates, respectively (P < 0.001, P < 0.001, P < 0.001, P < 0.001). The agreement of ANKUTRIAGE with Pediatric Canadian Triage and Acuity Scale was found to be 0.94 (95% confidence interval [CI], 0.93–0.94), with an Emergency Severity Index of 0.75 (95% CI, 0.70–0.80). The interrater agreement between 2 evaluators who used ANKUTRIAGE reflected as excellent consistency 0.92 (95% CI, 0.89–0.95; κ > 0.8).

Conclusions

ANKUTRIAGE demonstrated high agreement with clinical outcomes and with proven triage systems and reflected high reliability between users. ANKUTRIAGE will enable a more standardized and practical triage, especially in crowded pediatric emergency departments and in situations where triage is performed by health professionals with different experience and professions.
Hepcidin Alleviates LPS-Induced ARDS by Regulating the Ferritin-Mediated Suppression of Ferroptosis
Authors: Jiao Yang , Yong Chaoying , Zhang Renzi , Qi Di , Wang Daoxin
Published: May 2022

The effects of ferroptosis, an iron-dependent cell death, on acute respiratory distress syndrome (ARDS) remain largely elusive. Hepcidin, encoded by the HAMP gene, affects inflammation, and iron homeostasis. The present study aimed to investigate whether hepcidin protects against ferroptosis in lipopolysaccharide (LPS)-induced ARDS. Our results confirmed that ferroptosis aggravated lung inflammation and damage in LPS-induced ARDS. Hepcidin defended against ferroptosis, with results similar to those of the ferroptosis inhibitor ferrostatin-1 (Fer-1). Moreover, hepcidin decreased iron uptake, as determined by Transferrin Receptor 1 (TfR1) expression levels, and increased iron storage, based on ferritin heavy chain (FTH) expression. The effects of hepcidin on the A549 cell line were in line with the in vivo results. In addition, we used si-FTH to knock down FTH expression and found that this suppressed the ability of hepcidin to protect against ferroptosis. Collectively, our data suggest that hepcidin inhibits ferroptosis by increasing FTH expression in LPS-induced ARDS; thus, hepcidin may represent a possible treatment targeting ferroptosis.
Transthoracic Esophagectomy: Hand-sewn Versus Side-to-side Linear-stapled Versus Circular-stapled Anastomosis: A Systematic Review and Meta-analysis
Authors: Schlottmann Francisco , Angeramo Cristian A. , Bras Harriott Camila , Casas María A. , Herbella Fernando A.M. , Patti Marco G.
Published: May 2022

Background:

Three anastomotic techniques are mostly used to create an esophagogastric anastomosis in a transthoracic esophagectomy: hand-sewn (HS), side-to-side linear-stapled (SSLS), and circular-stapled (CS). The aim of this study was to compare surgical outcomes after HS, SSLS, and CS intrathoracic esophagogastric anastomosis.

Materials and Methods:

A systematic review using the MEDLINE database was performed to identify original articles analyzing outcomes after HS, SSLS, and CS esophagogastric anastomosis. The main outcome was an anastomotic leakage rate. Secondary outcomes included overall morbidity, major morbidity, and mortality. A meta-analysis of proportions and linear regression models were used to assess the effect of each anastomotic technique on the different outcomes.

Results:

A total of 101 studies comprising 12,595 patients were included; 8835 (70.1%) with CS, 2532 (20.1%) with HS, and 1228 (9.8%) with SSLS anastomosis. Anastomotic leak occurred in 10% [95% confidence interval (CI), 6%-15%], 9% (95% CI, 6%-13%), and 6% (95% CI, 5%-7%) of patients after HS, SSLS, and CS anastomosis, respectively. Risk of anastomotic leakage was significantly higher with HS anastomosis (odds ratio=1.73, 95% CI: 1.47-2.03, P<0.0001) and SSLS (odds ratio=1.68, 95% CI: 1.36-2.08, P<0.0001), as compared with CS. Overall morbidity (HS: 52% vs. SLSS: 39% vs. CS: 35%) and major morbidity (HS: 33% vs. CS: 19%) rates were significantly lower with CS anastomosis. Mortality rate was 4% (95% CI, 3%-6%), 2% (95% CI, 2%-3%), and 3% (95% CI, 3%-4%) after HS, SSLS, and CS anastomosis, respectively.

Conclusion:

HS and SSLS intrathoracic esophagogastric anastomoses are associated with significantly higher rates of an anastomotic leak than CS anastomosis.

Authors: Karabulut Mehmet , Donmez Turgut , Sahbaz Nuri A. , Akarsu Cevher , Ferahman Sina , Surek Ahmet , Gemici Eyup , Aydin Husnu , Sunamak Oguzhan , Dural Ahmet C.
Published: May 2022

Background:

Conversion is a surgical concern because the surgical technique can change during surgery. Surprisingly, there is no study in the literature on the causes and risk factors leading to conversion in laparoscopic total extraperitoneal inguinal repair (TEP). There is also no consensus on the prevention and causes of this condition in TEP. The aim of this study was to evaluate the risk factors underlying the development of conversion during TEP.

Materials and Methods:

We recruited 962 consecutive patients who underwent TEP between May 2016 and May 2021. All data were collected retrospectively. The outcomes of patients who converted to open surgery were compared with those without conversion. Multivariate analysis identified independent risk factors for conversion.

Results:

The overall incidence of conversion was 4.05% (n=39). The median age was 42 years (18 to 83) and body mass index was 25.2 kg/m2 (15.67 to 32.9). Significant clinical factors associated with conversion included old age, American Society of Anesthesiologists (ASA) score, large peritoneal tear (PT), Charlson comorbidity index, previous surgery, large hernial defects, presence of scrotal hernia, and the defect size of inguinal hernia. Multivariate analysis identified independent risk factors for conversion: large hernial defect, large PT, previous lower abdominal surgery, previous hernia surgery, and scrotal hernia.

Conclusion:

Conversion is a minor complication seen during TEP and its incidence varies depending on many factors. Previous lower abdominal surgery and a large PT carries a 6-fold increased risk for conversion from laparoscopic to open surgery during TEP.

Authors: Şen Ozan , Sekmen Ümit , Türkçapar Ahmet G.
Published: May 2022

Aim:

The aim of this study is to reveal incidence of gastroesophageal reflux disease (GERD) after laparoscopic sleeve gastrectomy (LSG) and to determine the effect of LSG with hiatal hernia repair on GERD.

Methods:

A total of 440 patients, 395 of them underwent primary LSG (group A) and 45 of them underwent LSG with concomitant hiatal hernia repair (group B) between March 2018 and September 2020 were included in the study. Presence of hiatal hernia was evaluated with endoscopy and confirmed intraoperatively. Patients were evaluated for GERD symptoms in the pre and postoperative period. Two groups’ data were compared.

Results:

Mean age of the 440 patients was 38.4±11 years (56% female) and mean body mass index was 44.2±7 kg/m2. Symptomatic GERD was detected in 103 (23.4%) and hiatal hernia was detected in 45 (10.2%) patients. İn the preoperative assessment there was no difference with regard to demographics and symptomatic GERD between the 2 groups. Mean duration of follow-up was 17±5.7 (12 to 28) months in the overall study population. Mean body mass index decreased to 28.3±4.9 kg/m2 at 12 months after LSG. Excess weight loss ratio was found to be 81±20.4%. The rate of symptomatic GERD after LSG in group A was found to be 20% (n=79/395). Of these patients, 46 (11.6%) had de novo GERD and 33 (38%) had persistent GERD. GERD resolved completely in 54 (62%) patients. In the group B, the rate of symptomatic GERD was detected as 33% (n=15/45) (P=0.04). The rate of de novo GERD (20%) was also higher in group B (P=0.03). The rate of persistent GERD (37%) and GERD resolution (62%) were similar in both groups.

Conclusion:

İn our study, symptomatic and de novo GERD rates were detected to be higher in the LSG+HH group than LSG alone.

Authors: Sasaki Toshihide , Yang Ching-Yao , Nakagawa Kenji , Nagai Minako , Nishiwada Satoshi , Terai Taichi , Sho Masayuki
Published: May 2022

Background:

Comparative studies regarding single-incision laparoscopic distal pancreatectomy (SILS-DP) are limited. This study aimed to compare the short-term outcomes of SILS-DP with conventional laparoscopic DP (C-LDP) under strict indication criteria.

Materials and Methods:

We retrospectively reviewed the patient characteristics and surgical outcomes of those who underwent either SILS-DP or C-LDP at National Taiwan University (NTU) and C-LDP at Nara Medical University (NMU) between 2009 and 2019. SILS-DP was indicated for benign or low-grade malignant pancreatic tail tumors and was performed along with splenectomy.

Results:

We compared 12 cases of SILS-DP with 31 of C-LDP from NTU and 17 of C-LDP from NMU. Patients in the SILS-DP group had significantly less blood loss than the C-LDP group at NTU (P=0.028). Postoperative outcomes, including the postoperative hospital stay and clinically relevant pancreatic fistula, were not significantly different between the 2 groups. Although SILS-DP was performed by a surgeon who was well-experienced with laparoscopic surgeries, the first few cases had a larger amount of blood loss, longer operation time, and a higher rate of complications. Such unfavorable outcomes were likely to be resolved shortly. No reoperations and deaths were noted.

Conclusion:

SILS-DP is feasible when performed by an experienced surgeon and in carefully selected patients.
GlycoVHH: Introducing N-glycans on the camelid VHH antibody scaffold - Optimal sites and use for macrophage delivery

As small and stable high-affinity antigen binders, VHHs boast attractive characteristics both for therapeutic use in various disease indications, and as versatile reagents in research and diagnostics. To further increase the versatility of VHHs, we explored the VHH scaffold in a structure-guided approach to select regions where the introduction of an N-glycosylation N-X-T sequon and its associated glycan should not interfere with protein folding or epitope recognition. We expressed variants of such glycoengineered VHHs in the Pichia pastoris GlycoSwitchM5 strain, allowing us to pinpoint preferred sites at which Man5GlcNAc2-glycans can be introduced at high site occupancy without affecting antigen binding. A VHH carrying predominantly a Man5GlcNAc2 N-glycan at one of these preferred sites showed highly efficient, glycan-dependent uptake by Mf4/4 macrophages in vitro and by alveolar lung macrophages in vivo, illustrating one potential application of glyco-engineered VHHs: a glycan-based targeting approach for lung macrophage endolysosomal system delivery. The set of optimal artificial VHH N-glycosylation sites identified in this study can serve as a blueprint for targeted glyco-engineering of other VHHs, enabling site-specific functionalization through the rapidly expanding toolbox of synthetic glycobiology.
LDL1 and LDL2 histone demethylases interact with FVE to regulate flowering in Arabidopsis
Authors: Mahima  , Chatterjee Sourav , Singh Sharmila , Sarkar Ananda K.
Published: May 2022

In higher plants, epigenetic modifications provide a stage for both transient and permanent cellular reprogramming required for vegetative to reproductive phase transition. Arabidopsis LSD1-like 1 (LDL1), a histone demethylase positively regulates floral transition, but the molecular and biochemical nature of LDL1 mediated flowering is poorly understood. Here we have shown that LDL1 mediated regulation of flowering is dependent on MADS AFFECTING FLOWERING 4 (MAF4) and MAF5 floral repressors. LDL1 binds on the chromatin of MAF4 and MAF5 and removes H3K4me2 activation marks to repress their expression. Further we show that LDL2 negatively regulates the expression of MAF4 and MAF5 redundantly with LDL1. Both LDL1 and LDL2 interact with an autonomous flowering pathway protein, FLOWERING LOCUS VE (FVE), to regulate the floral transition and thus could be a part of the FVE-corepressor complex. We show that MAF5 interacts with other floral repressors FLC and SHORT VEGETATIVE PHASE (SVP) and repress the expression of FT to delay floral transition. Thus, our results deepen the mechanistic understanding of LDL1/LDL2-FVE mediated floral transition in Arabidopsis.

Does growth of nonperforming loan ratio have a temporal impact on private credit growth in Bangladesh economy?
Authors: Ashikuzzaman N.M.
Published: May 2022

Purpose

This paper addresses the question “Does the growth of nonperforming loan ratio (GNPL) have a temporal impact on private credit growth (PCG)?” for the Bangladesh banking industry during and after the global financial crisis of 2008.

Design/methodology/approach

It employs the autoregressive distributed lag (ARDL) model to examine the temporal equilibrium relationship and causality between PCG and GNPL.

Findings

The results of ARDL bound tests confirm the existence of a single cointegrating vector and temporal equilibrium relationship between variables of interest. According to the error correction mechanism (ECM), there is unidirectional causality from GNPL to PCG in the long run and short run. In the long run, higher GNPL curtails PCG since bankers use the nonperforming loan ratio as a signal and indicator of credit risk in their loan decision-making. In the short run, GNPL positively impacts PCG. It may be because banks go through a rigorous process before declaring a loan as nonperforming that takes time. At the same time, bankers' loan decisions may also be guided by the banks myopic concern of reputation in the short run.

Practical implications

The paper recommends policy prescriptions for the bank risk management, regulatory bodies and the legal authorities. The lending policy of banks should consider the legacy of bad assets. The efficiency of the legal system can also aid in effectively implementing the regulatory guidelines.

Originality/value

The paper inaugurates a bivariate cointegration analysis between PCG and GNPL in the literature. It has utilized quarterly aggregate data in the context of a developing economy like Bangladesh.
Does hierarchical ranking matter to corporate innovation efficiency? An empirical study based on a corporate culture of seniority
Authors: Xu Xixiong , Lin Cuiliang , Duan Lingling
Published: May 2022

Purpose

This study aims to investigate whether and how corporate seniority culture (a form of high power distance or hierarchy), a typical feature of Confucian norms, affects the corporate innovation efficiency in emerging markets.

Design/methodology/approach

This study defines and measures seniority culture through the ranking method of independent directors in company’s annual report. Unlike most companies in the USA where directors are listed alphabetically, the ranking of directors in China is meaningful and reflects hierarchy. This study considers a firm with seniority if independent directors are ranked according to their status, including age, social position and political connection. Using data from Chinese listed companies between 2009 and 2013, this study conducts multiple regressions to examine the impact of seniority on innovative efficiency.

Findings

The empirical results show that seniority culture is negatively associated with innovative efficiency. Moreover, the negative association between a corporate culture of seniority and innovative efficiency is more pronounced in firms with more male executives and knowledge-intensive firms. Further analysis reveals that seniority culture expands pay disparities among different classes, hinders their enthusiasm to communicate and ultimately damages the corporate efficiency of innovation.

Practical implications

Corporate seniority culture is an essential factor that may hinder employee communication and inhibit innovation efficiency. Therefore, companies should break the identity barrier at different levels and advocate a culture of equality to promote information exchange and knowledge sharing among employees.

Originality/value

This study extends the field of literature on the determinants of corporate innovation efficiency and deepens our theoretical understanding of the negative impact of corporate seniority culture.

Authors: Shroff Arvind , Shah Bhavin J.
Published: May 2022

Learning outcomes

Need for preventive health care: To comprehend the contribution of preventive health care in improving the health quotient. Sri Sathya Sai Sanjeevani Hospital (SSSSH) and its initiative is an apt example of the wonder which preventive care can bring in the context of rural health. Community participation: The case can be instrumental in showing the pathway to encourage community involvement in mainstream health by promoting the holistic model of SSSSH that understands mothers and children's health profile and needs, especially in the unreached rural segments of an emerging economy like India. Importance of healthy childhood: World Health Organization (WHO) promotes the school health programme to prevent health risks among children by inculcating healthy behaviours during childhood. The successful SSSSH model proves that it is implementable by integrating comprehensive health education modules in the existing institutions for medical care.

Case overview/synopsis

The challenge of a healthy childhood is inadequate availability and accessibility of quality care. Non-awareness of the parents is also a significant reason for the children who miss the benefit of a happy childhood. While much is planned by the Government and some part of it being executed, this case highlights the effectiveness of the maternal and child health programme executed by the Sri Sathya Sai Sanjeevani Hospital (SSSSH). This initiative fulfills the dire need of ensuring the preventive healthcare component leading to safe motherhood and safe birth of healthy children. Further, the case is also the culmination of pin-pointed innovative awareness activities such as school health screening and the Divine Mother and Child Health Program (DMCHP). It opens up the discussion on the current model of health care followed by SSSSH, Raipur, and its impact in the local areas to decide on its expansion across the country for nationwide implementation.

What affects the online ratings of restaurant consumers: a research perspective on text-mining big data analysis
Authors: Liu Jun , Yu Yunyun , Mehraliyev Fuad , Hu Sike , Chen Jiaqi
Published: May 2022

Purpose

Despite a significant focus on customer evaluation and sentiment analysis, limited attention has been paid to discrete emotional perspective in terms of the emotionality used in text. This paper aims to extend the general-sentiment dictionary in Chinese to a restaurant-domain-specific dictionary, visualize spatiotemporal sentiment trends, identify the main discrete emotions that affect customers’ ratings in a restaurant setting and identify constituents of influential emotions.

Design/methodology/approach

A total of 683,610 online restaurant reviews downloaded from Dianping.com were analyzed by a sentiment dictionary optimized by the authors; the main emotions (joy, love, trust, anger, sadness and surprise) that affect online ratings were explored by using multiple linear regression methods. After tracking these sentiment review texts, Latent Dirichlet Allocation (LDA) and LDA models with term frequency-inverse document frequency as weights were used to find the factors that constitute influential emotions.

Findings

The results show that it is viable to optimize or expand sentiment dictionary by word similarity. The findings highlight that love and anger have the highest effect on online ratings. The main factors that constitute consumers’ anger (local characteristics, incorrect food portions and unobtrusive location) and love (comfortable dining atmosphere, obvious local characteristics and complete supporting services) are identified. Different from previous studies, negativity bias is not observed, which poses a question of whether it has to do with Chinese culture.

Practical implications

These findings can help managers monitor the true quality of restaurant service in an area on time. Based on the results, restaurant operators can better decide which aspects they should pay more attention to; platforms can operate better and can have more manageable webpage settings; and consumers can easily capture the quality of restaurants to make better purchase decisions.

Originality/value

This study builds upon the existing general sentiment dictionary in Chinese and, to the best of the authors’ knowledge, is the first to provide a restaurant-domain-specific sentiment dictionary and use it for analysis. It also reveals the constituents of two prominent emotions (love and anger) in the case of restaurant reviews.
The impacts of high-quality relationships on employee outcomes; evidence from restaurant staff in India
Authors: Foroutan Taraneh , Bouzari Mona , Safavi Homayoun Pasha
Published: May 2022

Purpose

This paper aims to develop a research model that investigates the probable antecedents and outcomes of psychological capital (PSY-capital). More specifically, high-quality relationships (HQRs) and psychological safety (PSY-safety) are tested as the antecedents and organizational deviant behaviors (ODBs) is tested as the outcome.

Design/methodology/approach

Data was gathered from the restaurant staff and their direct supervisors through a 10-day time-lag design in two different rounds. Structural equation modeling was used to evaluate the direct and mediation.

Findings

Drawing upon social identity theory (SIT), the findings reveal that PSY-safety functions as a mediator of the effect of HQRs on PSY-capital. Additionally, the results proved that PSY-capital mediates the relationship between PSY-safety and ODBs.

Practical implications

Considering the results, restaurant managers should pay ample attention to and make every effort to develop HQRs among organizational members. Through this, manager paves the way for PSY-safety which causes employees to develop PSY-capital and eventually display less deviance. Additionally, the authors recommend that company managers serve as role models for their staff, sharing information with and respecting them to create an environment of mutual trust, similar goals and knowledge sharing.

Originality/value

This research contributes significantly to the existing hospitality literature (specifically foodservice) by testing the mechanism through which HQRs lead to PSY-capital and the mediation effect of PSY-capital in the relationship between PSY-safety and ODBs.

Authors: Samanta Alok Kumar , G. Varaprasad , Gurumurthy Anand
Published: May 2022

Purpose

Health care organisations implement lean six sigma (LSS) methodology to achieve improved performance in terms of cost, quality and productivity. However, the way it gets implemented differs between organisations. Hence, this paper deal with a review of case studies describing the implementation of LSS in health care organisations to understand the nuances of implementation and identify future research directions.

Design/methodology/approach

The journal articles indexed in the Web of Science and Scopus database were filtered out. In total, 154 articles were evaluated using specific structural dimensions to categorise the literature into various groups, and content analysis was performed to synthesise the same.

Findings

This review revealed that the number of articles publishing the application of LSS in health care has been increasing in the last five years. Academic hospitals play a pivotal role to bridge the gap between LSS theory and practice. Despite this fact, certain themes remain unexplored. Not many studies are available that document the application of LSS in non-clinical areas such as pharmacy, internal logistics, maintenance and medical records. Only 20% of articles mentioned the post-intervention data up to three years, thus questioning the sustainability aspect of the achieved improvements.

Research limitations/implications

Various research gaps were identified, which can be used by the researchers to build the body of knowledge in the domain of LSS in health care.

Practical implications

This review provides a diversified view regarding the utility of LSS in the health care scenario. The findings will provide valuable insights for the health care practitioners regarding tools, techniques, drivers and performance measures.

Originality/value

To the best of the authors’ knowledge, this is the first study to review only the case studies that describe the implementation of LSS in the health care sector.

Authors: Mehmood Khalid , Jabeen Fauzia , Al Hammadi Khadija Ibrahim Salim , Al Hammadi Asma , Iftikhar Yaser , AlNahyan Moza Tahnoon
Published: May 2022

Purpose

Drawing on the self-determination theory, this cross-cultural study aims to examine the associations between the dualistic framework of work passion and work outcomes (job satisfaction, job engagement and workaholism).

Design/methodology/approach

Using data from a time-lagged design with two-waves, service organizations employees of the UAE (n = 150) and Canada (n = 154) participated in the study. Hierarchical regression analysis is used to analyze the associations among the variables.

Findings

The study results support the harmonious and obsessive passion relationships with the identified work outcomes. In both the UAE and Canada, harmonious and obsessive passion predicted all three hypothesized work outcomes (workaholism, job satisfaction and job engagement). The study also acknowledged various culture-specific work passion effects.

Research limitations/implications

The study encompasses the dichotomy of the work passion paradigm to compare between East and West. The examination of the work passion results offers a precise method to examine in what manner the two types of passion is linked to different work outcomes. Harmonious and obsessive passion is associated with negative (workaholism) and positive (job satisfaction and job engagement) outcomes. Accordingly, the findings strengthen the conceptual outline of the passion construct. Moreover, the research highlighted the importance of enriching the organization's environment with passionate human capital. This study shall help the decision-makers to formulate the suitable strategies to imbibe passion within the work culture.

Originality/value

This study contributes to the literature by being the first to compare the influence of harmonious and obsessive passion on work outcomes between the East and West cultures. Also, in this study, we draw upon the self-determination theory to investigate how work passion affects employees' work outcomes in a cross-cultural setting.
Understanding the role of anticipated loss and gain during consumer competition: the moderation of purchase importance and prior brand attitude
Authors: Kim Dongyoup , Park Jungkun , Le Hoang T.P.M , Choi Duckyeon
Published: May 2022

Purpose

This study examined how consumer competition affects purchase intention. The anticipated loss of not buying and the anticipated gain of buying are considered the underlying mechanism. This research also demonstrated the moderating effects of situational factors such as purchase importance and prior brand attitude.

Design/methodology/approach

In total, 200 responses were collected from an experiment that manipulated the level of consumer competition in the retail environment. Structural equation modeling (SEM) and multigroup analysis were used to test the hypotheses.

Findings

The results indicated that perceived competition positively affects both the anticipated loss of not buying and the anticipated gain of buying. Among these, only the anticipated gain of buying significantly increased purchase intention. However, for participants with lower purchase importance or prior brand attitude, both the anticipated loss of not buying and the anticipated gain of buying significantly affected purchase intention.

Research limitations/implications

The findings suggest an appropriate communication method when practicing retail strategies related to competition. In particular, the consideration of intervention of purchase importance and prior brand attitude helps retail managers execute marketing strategies more effectively.

Originality/value

This study verified the effect of consumer competition on purchase intention in terms of anticipated losses and gains related to buying. Moreover, the moderation effects of situational factors such as purchase importance and prior brand attitude were initially examined in the context of consumer competition.
Impact of just-in-time (JIT) on supply chain disruption risk: the moderating role of supply chain centralization
Authors: Ye Yuxiao , Suleiman Mohammed Ali , Huo Baofeng
Published: May 2022

Purpose

The relationship between just-in-time (JIT) and supply chain disruption risk is unclear from the existing literature. This paper aims to investigate the impact of supplier JIT and customer JIT on supplier disruption risk (SDR), internal disruption risk (IDR), and customer disruption risk (CDR) and explore the moderating role of supply chain centralization.

Design/methodology/approach

Based on survey data collected from 213 manufacturing firms in China, this study employs structural equation modeling with SmartPLS 3.0 to test the main proposed model and applies an ordinary least square regression to test the moderating effect.

Findings

The results demonstrate that supplier JIT is positively related to SDR and negatively associated with IDR. Customer JIT is positively associated with CDR but has no significant effect on IDR. The results also show that SDR and CDR lead to IDR and mediate the relationship between supplier JIT, customer JIT, and IDR. In addition, supply chain centralization amplifies the positive impacts of supply chain JIT on SDR and IDR.

Originality/value

This study makes two main contributions. First, the study provides a comprehensive analysis of the relationship between supply chain JIT and disruption risk. Second, the study addresses that implementing JIT in a supply chain with a centralized decision-making structure leads to a higher level of disruption risk.

This paper examines the socio-political affordances of metrics in research evaluation and the consequences of epistemic injustice in research practices and recorded knowledge.

Design/methodology/approach

First, the use of metrics is examined as a mechanism that promotes competition and social acceleration. Second, it is argued that the use of metrics in a competitive research culture reproduces systemic inequalities and leads to epistemic injustice. The conceptual analysis draws on works of Hartmut Rosa and Miranda Fricker, amongst others.

Findings

The use of metrics is largely driven by competition such as university rankings and league tables. Not only that metrics are not designed to enrich academic and research culture, they also suppress the visibility and credibility of works by minorities. As such, metrics perpetuate epistemic injustice in knowledge practices; at the same time, the reliability of metrics for bibliometric and scientometric studies is put into question.

Social implications

As metrics leverage who can speak and who will be heard, epistemic injustice is reflected in recorded knowledge and what we consider to be information.

Originality/value

This paper contributes to the discussion of metrics beyond bibliometric studies and research evaluation. It argues that metrics-induced competition is antithetical to equality and diversity in research practices.
Continuous auditing in public sector and central banks: a framework to tackle implementation challenges
Authors: Polizzi Salvatore , Scannella Enzo
Published: May 2022

Purpose

This paper aims to analyse the implementation challenges faced by internal audit departments of public sector organisations and central banks when implementing continuous auditing (CA) systems. CA aims to monitor internal control systems and risk levels on a continuous basis to support the audit process. This study identifies the implementation challenges of CA systems and proposes adequate countermeasures.

Design/methodology/approach

This study employs the design science information system research and the design science research process methodologies to ensure the rigor of this analysis. These research methodologies are adopted to tackle identified organisational problems and propose solutions. This methodological approach consists in the following phases: identification of the problems and motivation; definition of the objectives of the solution; research design and development; evaluation; communication.

Findings

This study detects several implementation challenges for public sector organisations and central banks and proposes adequate solutions. This study finds that these challenges are related to organisations’ complexity, institutional rigidity, potential threats to internal auditors’ independence and the issue of considering CA system as a “real time error correction” mechanism. The solutions involve the development of a business process focussed audit approach to enable internal auditors to analyse CA indicators, and the use of CA systems to support each phase of the audit process.

Originality/value

This study contributes to the scant strand of literature on internal auditing in central banks. Given the exceptional demand for guidance concerning internal auditing in the public sector and in central banks, this paper provides guidelines for these organisations to implement CA systems and to tackle implementation challenges. The analysis allows internal audit departments within central banks to better support their organisations in the achievement of their important regulatory and policy objectives.
Do fear and perceived knowledge of Covid-19 drive sustainable consumption behaviour in Muslims? The mediating role of religiosity
Authors: Batool Aysha , Shabbir Rizwan , Abrar Muhammad , Bilal Ahmad Raza
Published: May 2022

Purpose

This research aims to investigate the impact of fear and perceived knowledge (PK) of Covid-19 on the sustainable consumption behaviour (SCB) of Muslim consumers and to test the mediating role of (intrinsic) religiosity.

Design/methodology/approach

A total of 417 responses were collected during Covid-19 lockdown through an online structured survey using the snowball technique. A two-step research approach was adopted. In Study 1, an exploratory factor analysis was performed on the SCB measurement scale through SPSS. In Study 2, hypothesised associations were analysed using SmartPLS-SEM.

Findings

PK of Covid-19 pandemic directly motivates SCB in Muslim consumers, whereas fear has no direct effect on any factor of SCB. Religiosity is found to be a significant driver of SCB. Indirect effects also depict that religiosity positively mediates the association between fear and SCB as well as PK and SCB.

Practical implications

The study may guide policymakers and marketers in using the current pandemic as a tool to inspire sustainable consumption. Religious values, teachings and knowledge about the pandemics can be publicised to create awareness and induce desired behaviour to cope with adverse events and adopt sustainable consumption patterns and lifestyles among Muslim consumers.

Originality/value

The article is the pioneer of its kind to present survey research about Covid-19 fear and PK’s impact on SCB through religiosity. It adds to the Islamic marketing literature about religiosity, coping theory, PK and fear of pandemics and their role in transitioning Muslim consumers towards SCB. Moreover, the use of partial least squares structural equation modelling in the context of Covid-19 research was extended.
Regulatory intervention and audit quality: new evidence from audit firm suspension
Authors: Feng Zhuoan , Li Lina Zixuan , Wong Hau Yan , Wong Jilnaught
Published: May 2022

Purpose

This paper aims to examine how auditors respond through audit fees and audit quality following disciplinary actions imposed by audit regulators in an emerging market setting.

Design/methodology/approach

This paper uses the disciplinary actions in 2017 against two major audit firms in China as an exogenous shock to examine the effect of tougher enforcement actions on auditor behavior as reflected in their emended audit fees and audit quality. This paper sampled from publicly listed firms in China with requisite data for the period 2015 through 2018. Using a difference-in-differences model, this paper examines whether the enforcement action (i.e. the suspension of audit firms) significantly impacted the audit fees and audit quality for clients of the disciplined audit firms (hereafter, suspended audit firms) in the two-year period postsuspension relative to audit firms that were not disciplined (hereafter, nonsuspended audit firms).

Findings

This paper finds evidence of increased audit fees and improved audit quality by the suspended audit firms relative to the nonsuspended audit firms in the two-year period postsuspension. These findings suggest that in contrast to symbolic disciplinary actions such as public censures documented in prior literature (Boone et al.,2015), tougher punitive disciplinary actions are followed by an increase in audit fees and an improvement in audit quality by the suspended audit firms. This paper also finds that the deterrent effect from the audit firm suspension is exclusive to the penalized audit firms and had no positive spillover effects on their peers.

Research limitations/implications

A limitation of this study is the focus on the effect of audit firm suspension against two large local audit firms in China. Given the unique characteristics of the Chinese audit market and the Chinese regulatory environment, our findings may not be generalizable to audit firms in other countries and jurisdictions, especially where the audit market is dominated by the international Big 4 auditors that possess greater brand name capital than second-tier local audit firms.

Originality/value

This paper provides novel evidence on the impact of strengthened enforcement on auditor behavior in an emerging market setting. This paper contributes to the existing literature examining the impact of regulatory interventions on financial reporting outcomes and audit quality. While there is evidence on how regulations affect financial statement preparers’ demand for high audit quality, there is limited research on how regulatory interventions affect auditor’s incentive to supply higher audit quality. This paper also contributes to the scant existing evidence on the effect of disciplinary actions against audit firms in emerging economies.
Optimization method of urban rail train operational plan based on O-D time-varying demand
Authors: Shi Feng , Tu Xian , Zhao Shuo
Published: May 2022

Purpose

Under the constraints of given passenger service level and coupling travel demand with train departure time, this study optimizes the train operational plan in an urban rail corridor to minimize the numbers of train trips and rolling stocks considering the time-varying demand of urban rail passenger flow.

Design/methodology/approach

The authors optimize the train operational plan in a special network layout, i.e. an urban rail corridor with dead-end terminal yard, by decomposing it into two sub-problems: train timetable optimization and rolling stock circulation optimization. As for train timetable optimization, the authors propose a schedule-based passenger flow assignment method, construct the corresponding timetabling optimization model and design the bi-directional coordinated sequential optimization algorithm. For the optimization of rolling stock circulation, the authors construct the corresponding optimization assignment model and adopt the Hungary algorithm for solving the model.

Findings

The case study shows that the train operational plan developed by the study's approach meets requirements on the passenger service quality and reduces the operational cost to the maximum by minimizing the numbers of train trips and rolling stocks.

Originality/value

The example verifies the efficiency of the model and algorithm.

Authors: Cooney Haynes , Dencik Jacob , Marshall Anthony
Published: May 2022

Purpose

Recent research conducted by the IBM Institute for Business Value found that 53 percent of organizations will position environmental sustainability as a top business priority by 2024.

Design/methodology/approach

The 3000 CEOs in our 2022 CEO study report that the greatest pressure they experience for improved sustainability and transparency now comes from their board, investors and ecosystem partners.

Findings

For successful organizations, sustainability is an integral part of the business strategy.

Practical/implications

Moving toward a more sustainable enterprise is an opportunity to transform and drive innovation throughout and beyond the organization.

Originality/value

While most organizations now have a sustainability strategy, only 37 percent have aligned sustainability objectives with their business strategies. Leading organizations co-create with ecosystem partners in new ways, creating new business platforms, pursuing innovation and aligning sustainability measures.
In-store technologies to improve customer experience and interaction: an exploratory investigation in Italian travel agencies
Authors: Dini Mauro , Splendiani Simone , Bravi Laura , Pencarelli Tonino
Published: May 2022

Purpose

This paper aims to deepen understanding of the role played by new technological tools used in customer–travel agency (TA) interactions by analysing the TA owner/managers' perceptions, pre- and post-Covid-19, regarding the effectiveness of in-store traditional and innovative tools.

Design/methodology/approach

This exploratory study is based on a questionnaire-based survey conducted among Italian TAs and distributed via email from September 2020 to January 2021.

Findings

The study highlights how, even among TAs, the role of in-store technology is gradually taking on greater importance, and it delves into the specific business and socio-demographic factors that seem to cause differences among agencies.

Research limitations/implications

The study focuses on the Italian context, which does not allow for any generalisations. Furthermore, it is only the travel agent perspective that is observed and not the consumer's.

Originality/value

In addition to helping to bridge the literature gap, this study on in-store technologies focuses on the TAs sector, where human resources and human relationships play a decisive role in customer experience and interaction. The paper investigates the travel agents' point of view regarding the introduction of new in-store technologies; it also highlights their growing adoption and use, overall, despite the travel catalogue still remaining the main tool for interacting with customers. The study also shows how the advent of Covid-19 has increased travel agents' propensity to use digital technologies.
