Published: September 2022

AbstractP450 superfamily (CYPs) has been known as contributors to the metabolites’ diversity and their promiscuous nature has led to the flexibility in substrate specificity and functional diversity. Current study was designed to investigate CYPs in the genome of an agarwood producing plant species named Aquilaria agallocha. Agarwood, the resinous fragrant wood with numerous phytochemicals, produced when an Aquilaria plant respond to wound and microbial infection. These chemicals are of great interest to industries ascribing it a high economic value. However, the pathways for the biosynthesis of these metabolites have not been studied in context of Aquilaria CYPs. We identified 136 A. agallocha CYP proteins from the genome, characterized and classified them into 8 clans and 38 families. Functional analysis unveiled their participation in terpenoids, phenolics, flavonoids and other valuable metabolites biosynthesis. Conserved motifs were detected and evolutionary analysis revealed duplicated and orthologous pairs. Potential members for the biosynthesis of sesquiterpenoids and phenylpropanoids reported in Aquilaria and agarwood were elucidated and validated through expression profiles in stress induced callus tissues and infected Aquilaria tress. This study provides a strong foundation for biochemical characterization of Aquilaria CYPs which will aid heterologous production of valuable phytochemicals and untangle molecular mechanism of agarwood formation.
Personnel brain-drain syndrome and quality healthcare delivery among public healthcare workforce in Nigeria
Authors: Akinwale Olusegun Emmanuel , George Olusoji James 
Published: September 2022

PurposeThe mass exodus of the professional healthcare workforce has become a cankerworm for a developing nation like Nigeria, and this worsens the already depleted healthcare systems in underdeveloped nation. This study investigated the rationale behind medical workers' brain-drain syndrome and the quality healthcare delivery in the Nigerian public healthcare sector.Design/methodology/approachTo stimulate an understanding of the effect of the phenomenon called brain drain, the study adopted a diagnostic research design to survey the public healthcare personnel in government hospitals. The study administered a battery of adapted research scales of different measures to confirm the variables of interest of this study on a probability sampling strategy. The study surveyed 450 public healthcare sector employees from four government hospitals to gather pertinent data. The study used a structural equation model (SEM) and artificial neural networks (ANNs) to analyse the collected data from the medical personnel of government hospitals.FindingsThe findings of this study are significant as postulated. The study discovered that poor quality worklife experienced by Nigerian medical personnel was attributed to the brain-drain effect and poor healthcare delivery. The study further demonstrated that job dissatisfaction suffered among the public healthcare workforce forced the workforce to migrate to the international labour market, and this same factor is a reason for poor healthcare delivery. Lastly, the study discovered that inadequate remuneration and pay discouraged Nigerian professionals and allied healthcare workers from being productive and ultimately pushed them to the global market.Originality/valuePractically, this study has shown three major elements that caused the mass movement of Nigerian healthcare personnel to other countries of the world and that seems novel given the peculiarity of the Nigerian labour market. The study is original and novel as much study has not been put forward in the public healthcare sector in Nigeria concerning this phenomenon.
What contributes to locavorism as a consumer ideology?
Authors: Balzano Marco , Vianelli Donata 
Published: September 2022

PurposeIn this study the authors aim to explore the factors that contribute to the formation of locavorism as a form of consumer ideology.Design/methodology/approachIn this study, the authors adopt an inductive approach by preselecting locavore consumers and conducting 43 semi-structured interviews, following the prescriptions of narrative-enquiry research.FindingsThe authors reveal that individual-level (i.e. values, beliefs and experiences) and social-level (i.e. groups, local communities and society) influences and exogenous factors can affect the formation of locavorism. Furthermore, the authors’ findings corroborate the concept advanced by prior studies that reinforcing loops exist among the three belief dimensions of locavorism.Practical implicationsFood producers can use these findings to shape their marketing strategies more effectively to target locavore consumers and/or stimulate the consumption of local food.Social implicationsIdentifying the influences of social- and individual-level factors on the formation of locavorism can contribute to the understanding of demand shifts towards local food consumption. Additionally, by revealing the modes of thought that formulate the ideologies of locavore consumers, the authors offer guidance in the development of policies that can safeguard local economies and traditions and reduce transport pollution and food waste in favour of sustainable local consumption.Originality/valueIn the present article the authors explore the psychological and contextual mechanisms that contribute to the formation of locavorism.
Employee emotional competence and service recovery satisfaction: the mediating role of consumer forgiveness
Authors: Umar Rana Muhammad , Saleem Salman 
Published: September 2022

PurposeEmployees' emotional competence (EEC) is gaining increasing attention in service failure and recovery research. This study investigates the mediating role of consumer forgiveness between perceived EEC and recovery satisfaction among casual dining consumers. Additionally, this study examines the effect of perceived EEC on recovery satisfaction across process failure vs outcome failure.Design/methodology/approachA critical incident technique (CIT) in conjunction with a self-administered online survey was carried out. Using the snowball sampling technique, a total of 204 useable responses were collected. To test the hypotheses, this study used partial least squares structural equation modeling (PLS-SEM).FindingsThe study finds that perceived EEC influences service recovery satisfaction. Additionally, the study identifies the mediating role of consumer forgiveness in the relationship between perceived EEC and recovery satisfaction. Multi-group moderation analysis shows that the relationship between perceived EEC and recovery satisfaction is weaker in process failures as compared to outcome failures.Practical implicationsBased on obtained results, this study recommends that after service failure consumer forgiveness and subsequent recovery satisfaction can be obtained with perceived EEC. To do so, managers need to incorporate emotional competence while recruiting and training the employees. Moreover, managers need to train employees on failure types and respective recovery strategies. Lastly, the study suggests that in emerging markets managers should pay greater emphasis on process failure, because such failure decreases customer satisfaction greatly than outcome failure.Originality/valueTo the authors' knowledge, this is the first study that investigates the impact of perceived EEC on consumer forgiveness which subsequently determines the recovery satisfaction in the emerging markets. It extends the application of the emotional contagion and affect infusion theories by exposing the effect of perceived EEC on recovery satisfaction through consumer forgiveness. In addition, the study provides insights that the influence of perceived ECC on recovery satisfaction significantly varies across service failure types.

Novel approach of detecting the black hole attack for vehicular ad-hoc networks based on capability indicators
Authors: El Houssaini Souad , El Houssaini Mohammed-Alamine , El Kafi Jamal 
Published: September 2022

Purpose
In vehicular ad hoc networks (VANETs), the information transmitted is broadcast in a free access environment. Therefore, VANETs are vulnerable against attacks that can directly perturb the performance of the networks and then provoke big fall of capability. Black hole attack is an example such attack, where the attacker node pretends that having the shortest path to the destination node and then drops the packets. This paper aims to present a new method to detect the black hole attack in real-time in a VANET network.

Design/methodology/approach
This method is based on capability indicators that are widely used in industrial production processes. If the different capability indicators are greater than 1.33 and the stability ratio (Sr) is greater than 75%, the network is stable and the vehicles are communicating in an environment without the black hole attack. When the malicious nodes representing the black hole attacks are activated one by one, the fall of capability becomes more visible and the network is unstable, out of control and unmanaged, due to the presence of the attacks. The simulations were conducted using NS-3 for the network simulation and simulation of urban mobility for generating the mobility model.

Findings
The proposed mechanism does not impose significant overheads or extensive modifications in the standard Institute of Electrical and Electronics Engineers 802.11p or in the routing protocols. In addition, it can be implemented at any receiving node which allows identifying malicious nodes in real-time. The simulation results demonstrated the effectiveness of proposed scheme to detect the impact of the attack very early, especially with the use of the short-term capability indicators (Cp, Cpk and Cpm) of each performance metrics (throughput and packet loss ratio), which are more efficient at detecting quickly and very early the small deviations over a very short time. This study also calculated another indicator of network stability which is Sr, which allows to make a final decision if the network is under control and that the vehicles are communicating in an environment without the black hole attack.

Originality/value
According to the best of the authors’ knowledge, the method, using capability indicators for detecting the black hole attack in VANETs, has not been presented previously in the literature.
Supervision or collusion? CEO–CFO social ties and financial reporting quality
Authors: Fang Xingtong , He Kaigang , Meng Yijun , Ye Jianfang 
Published: September 2022

PurposeSocial ties may either help chief executive officers (CEOs) supervise chief financial officers' (CFOs) behaviors effectively and improve financial reporting quality or lead to collusion and undermine financial reporting quality. Therefore, this paper examines the impact of social ties between CEOs and CFOs on financial reporting quality.Design/methodology/approachThis paper constructs the CEO–CFO social ties through their mutual alma mater or birthplace. Based on 6,787 Chinese non-financial firm-year observations from 2003 to 2020, the paper conducts an empirical test using the multiple regression method.FindingsThe main finding is that firms with CEO–CFO social ties are more likely to exhibit higher financial reporting quality. CEOs with social ties to CFOs can obtain a high level of information and exert a better supervisory and monitoring role. Further, CEO–CFO social ties are more effective when the CEO does not have a financial background and when the institutional environment is weak.Originality/valueThis paper mainly contributes to the literature exploring the impact of executive characteristics on financial reporting quality and the literature examining the relation between social ties and corporate behaviors. Meanwhile, the paper emphasizes the important role of social ties as an informal monitoring mechanism in practice.
Real earnings management and idiosyncratic return volatility
Authors: Habib Ahsan , Biswas Pallab Kumar , Ranasinghe Dinithi 
Published: September 2022

PurposeHigher real earnings management (REM) reduces financial reporting quality and increases the uncertainty of future cash flows and profitability among investors. This study asserts that REM-induced noise increases idiosyncratic return volatility (IVOL), aims to examine the association between REM and IVOL and further investigates whether information asymmetry, firm life cycle and economic policy uncertainty (EPU) moderate the association between REM and IVOL.Design/methodology/approachThe authors use 94,445 firm-year observations from the US over 1987 to 2019 and test this study’s hypotheses using ordinary least square regressions with robust standard errors clustered by firm. The authors use change analysis, two-stage models and the impact threshold of the confounding variable analysis to address endogeneity.FindingsThe authors find that REM increases IVOL. This positive association is more pronounced for firms with more information asymmetry, for firms in the mature stage of the life cycle, compared with their growth-stage counterparts; and during periods of high EPU.Originality/valueExtant research suggests that accrual manipulation increases IVOL. However, the shift from accrual manipulation to REM and the managerial preference towards REM suggests that it is important to explore the impact of REM on IVOL. Thus, the authors enhance the understanding of the impact of earnings management on IVOL by documenting that REM-induced noise increases IVOL. The authors further extend the limited research on the consequences of REM and report an adverse consequence.
Artificial intelligence and entrepreneurial ecosystems: understanding the implications of algorithmic decision-making for startup communities
Authors: Roundy Philip T. 
Published: September 2022

Purpose
Entrepreneurs are increasingly relying on artificial intelligence (AI) to assist in creating and scaling new ventures. Research on entrepreneurs’ use of AI algorithms (machine learning, natural language processing, artificial neural networks) has focused on the intra-organizational implications of AI. The purpose of this paper is to explore how entrepreneurs’ adoption of AI influences their inter- and meta-organizational relationships.

Design/methodology/approach
To address the limited understanding of the consequences of AI for communities of entrepreneurs, this paper develops a theory to explain how AI algorithms influence the micro (entrepreneur) and macro (system) dynamics of entrepreneurial ecosystems.

Findings
The theory’s main insight is that substituting AI for entrepreneurial ecosystem interactions influences not only entrepreneurs’ pursuit of opportunities but also the coordination of their local entrepreneurial ecosystems.

Originality/value
The theory contributes by drawing attention to the inter-organizational implications of AI, explaining how the decision to substitute AI for human interactions is a micro-foundation of ecosystems, and motivating a research agenda at the intersection of AI and entrepreneurial ecosystems.
Parental influence, financial literacy and investment behaviour of young adults
Authors: Chawla Deepak , Bhatia Shikha , Singh Sonali 
Published: September 2022

PurposeParents are the first and leading socialization agents for young adults. It is vital to recognize the influence of perceived parental financial behaviour in shaping the financial literacy and investment behaviour of their children. In this context, this paper aims to test the perceived parental influence on financial literacy. Additionally, the direct and indirect influence of financial literacy on investment behaviour of young adults is examined.Design/methodology/approachThis paper uses survey-based cross-sectional data. The partial least squares-structure equation model has been used to estimate and test the hypothesized relationships.FindingsPerceived parental financial behaviour has been found to significantly impact the level of financial literacy. In turn, financial literacy positively influences the investment behaviour of young adults. Moreover, the young adults’ perception of confidence over ability to take right financial decisions drives their decision to invest.Social implicationsThe results of this study imply that there is a need to have planned interventions from policymakers to ensure that young adults are financially literate. This may require introduction of planned programmes or workshops at middle or senior school levels. These programmes should help young adults understand the need for focused and long-term investing in the absence of social benefits.Originality/valueThis study is one of the preliminary works to examine the perceived parental influence on young adults’ financial literacy and further linking these with actual investment behaviour.
Seismic performance of continuous curved girder bridge with high pier in Maduo earthquake and characteristic analysis
Authors: Huang Yong , Song Guangyou , Li Guochang 
Published: September 2022

PurposeThe purpose of this study is to explore the seismic damage mechanism of the Dayemaling Bridge during the Maduo earthquake and discuss the seismic damage characteristics of the high-pier curved girder bridge.Design/methodology/approachIn this study, the numerical simulation method is used to analyze the seismic response using synthetic near-field ground motion records.FindingsThe near-field ground motion of the Maduo earthquake has an obvious directional effect, it is more likely to cause bridge seismic damage. Considering the longitudinal slope of the bridge and adopting the continuous girder bridge form, the beam end displacement of the curved bridge can be effectively reduced, and the collision force of the block and the bending moment of the pier bottom are reduced, so the curved bridge with longitudinal slope is adopted.Originality/valueCombined with the seismic damage phenomenon of bridges in real earthquakes, the seismic damage mechanism and vulnerability characteristics of high-pier curved girder bridges are discussed by the numerical simulation method, which provides technical support for the application of such bridges in high seismic intensity areas.
Evaluation of the efficiency of polyacrylamide and poly(MMA-HEMA) for the consolidation of vegetable-tanned leather artifacts
Authors: Abdel-Maksoud Gomaa , Abdallah Aya , Youssef Rana , Elsayed Doha , Labib Nesreen , Mohamed Wael S. , Ibrahim Medhat 
Published: September 2022

Purpose
This study aims to evaluate the efficiency of using some polymers at different concentrations in the consolidation of vegetable-tanned leather artifacts.

Design/methodology/approach
New vegetable-tanned leather samples were prepared. The consolidants used were polyacrylamide (PAM) and polymethyl methacrylate/hydroxyethyl methacrylate (MMA-HEMA). Accelerated heat aging was applied to the untreated and treated samples. Analytical techniques used were Fourier transform infrared spectroscopy (FTIR), digital microscope, scanning electron microscope (SEM), change of color and mechanical properties.

Findings
The characteristic FTIR bands showed the effect of accelerated heat aging on the molecular structure of the studied samples, but treated and aged treated samples used were better than aged untreated samples. Microscopic investigations (digital and SEM), and mechanical properties proved that 2% was the best concentration for polymers used. The change in the total color difference of the treated and aged treated samples was limited.

Originality/value
This study presents the important results obtained from PAM and poly(MMA-HEMA) used for the consolidation of vegetable-tanned leather artifacts. The best results of the studied polymers can be applied directly to protect historical vegetable-tanned leathers.
“Life is based on reciprocity, so be generous”: ethical work in doctoral acknowledgements
Authors: Grant Barbara M. , Sato Machi , Skelling Jules 
Published: September 2022

Purpose
This paper aims to explore doctoral candidates’ ethical work in writing the acknowledgements section of their theses. With interest in the formation of academic identities/subjectivities, the authors explore acknowledgements writing as always potentially a form of parrhesia or risky truth-telling, through which the candidate places themselves in their relations to others rather than in their claims to knowledge (Luxon, 2008).

Design/methodology/approach
Doctoral candidates from all faculties in one Japanese and one Aotearoa New Zealand university participated in focus groups where they discussed the genre of thesis acknowledgements, drafted their own version and wrote a reflective commentary/backstory.

Findings
Viewing the backstories through the lens of parrhesia (with its entangled matters of frankness, truth, risk, criticism and duty) showed candidates engaged in complex ethical decision-making processes with, at best, “ambiguous ethical resources” (Luxon, 2008, p. 381) arising from their academic and personal lives. Candidates used these resources to try and position themselves as both properly academic and more than academic – as knowing selves and relational selves.

Originality/value
This study bares the ethical riskiness of writing doctoral acknowledgements, as doctoral candidates navigate the tensions between situating themselves “truthfully” in their relations with others while striking the necessary pose of intellectual independence (originality). In a context where there is evidence that examiners not only read acknowledgements to ascertain independence, student and/or supervisor quality and the “human being behind the thesis” (Kumar and Sanderson, 2020, p. 285) but also show bias in those readings, this study advises reader caution about drawing inferences from acknowledgements texts. They are not simply transparent. As examiners and other readers make sense, judgments even, of these tiny, often fascinating, glimpses into a candidate’s doctoral experience, they need to understand that a host of unpredictable tensions with myriad ambiguous effects are present on the page.
