Published: June 2023

AbstractThe highly active family ofMutator(Mu) DNA transposons has been widely used for forward and reverse genetics in maize. There are examples ofMu-suppressible alleles which result in conditional phenotypic effects based on the activity ofMu. Phenotypes from theseMu- suppressible mutations are observed inMu-active genetic backgrounds, but absent whenMuactivity is lost. For someMu-suppressible alleles, phenotypic suppression likely results from an outward-reading promoter withinMuthat is only active when the autonomousMuelement is silenced or lost. We isolated 35Mualleles from the UniformMu population that represent insertions in 24 different genes. Most of these mutant alleles are due to insertions within gene coding sequences, but several 5’ UTR and intron insertions were included. RNA-seq andde novotranscript assembly were utilized to document the transcripts produced from 33 of theseMuinsertion alleles. For 20 of the 33 alleles, there was evidence of transcripts initiating within theMusequence reading through the gene. This outward-reading promoter activity was detected in multiple types ofMuelements and doesn’t depend on the orientation ofMu. Expression analyses ofMu-initiated transcripts revealed theMupromoter often provides gene expression levels and patterns that are similar to the wild-type gene. These results suggest theMupromoter may represent a minimal promoter that can respond to genecis-regulatory elements. Findings from this study have implications for maize researchers using the UniformMu population, and more broadly highlights a strategy for transposons to co-exist with their host.Article SummaryMutator(Mu) transposable elements are a widely used tool for insertional mutagenesis in maize and often insert in the 5’ regions of genes. The characterization of transcripts forMuinsertion alleles reveals complex transcripts. These often result in one transcript that covers the first portion of the gene terminating inMuand a second transcript initiating withinMucovering the latter portion of the gene. This may reflect a strategy forMuto minimize the consequences of insertions within genes.

Authors: Xu Huiyi , Gao Zhiming , Yang Yang , Hu Wenbin 
Published: June 2023

Purpose
The purpose of this study is to ensure the safe use of carbon fiber composite pressure vessels in the nuclear industry environment.

Design/methodology/approach
This study investigated the degradation behaviors of carbon fiber reinforced composite (CFRP) using the specific corrosive media HF solution, with a focus on the damage to the surface epoxy layer. The degradation behaviors of CFRP in HF solution were examined by electrochemical methods and surface characterization, using HCl, NaCl and NaF solution for comparison.

Findings
The results showed that the specimen in HF solution will have a value of |Z|0.01 Hz one order of magnitude lower, a substantially lower contact angle, more breakage of the surface epoxy and the stronger O─H peak and weaker C─O─C peak in the Fourier transform infrared spectrum, indicating severe hydrolytic damage to the surface epoxy.

The work focuses on the degradation damage to CFRP surface epoxy by specific corrosive media HF.
Corrosion behavior of TiC/amorphous carbon coated stainless steel as bipolar plate for proton exchange membrane fuel cell
Authors: Qin Zhenbo , Li Jiale , Zhang Yiwen , Wu Zhong , Hu Wenbin 
Published: June 2023

Purpose
The purpose of this paper is to improve the corrosion resistance of stainless-steel bipolar plate by magnetron sputtering.

Design/methodology/approach
TiC/amorphous carbon composite film was deposited by magnetron sputter at four different temperature of 25°C, 200°C, 300°C and 400°C. The morphology, composition and structure of the film were characterized by scanning electron microscopy, atomic force microscopy and X-ray photoelectron spectroscopy. And its corrosion behavior was analyzed through electrochemical impedance spectroscopy, potentiodynamic and potentiostatic polarization tests.

Findings
A compact TiC/amorphous carbon film was prepared by magnetron sputtering on 316L stainless steel, and the particles of the film were refined with the increase in sputtering temperature. High temperature promoted the formation of TiC and C–C sp2 hybrid carbon, but excessively high temperature caused the oxidation of Ti and a significant decrease in sp2 hybrid carbon. The corrosion resistance of the film increased with the temperature, and the corrosion current density polarization at 0.86 V and 1.8 V for TiC/a–C film prepared at 400 °C is only 1.2% and 43.2% of stainless steel, respectively.

Originality/value
The corrosion resistance of amorphous carbon films was improved by the doping of Ti carbide, and the appropriate sputtering temperature was obtained.
Forest fire detection in aerial vehicle videos using a deep ensemble neural network model
Authors: Sarikaya Basturk Nurcan 
Published: June 2023

Purpose
The purpose of this paper is to present a deep ensemble neural network model for the detection of forest fires in aerial vehicle videos.

Design/methodology/approach
Presented deep ensemble models include four convolutional neural networks (CNNs): a faster region-based CNN (Faster R-CNN), a simple one-stage object detector (RetinaNet) and two different versions of the you only look once (Yolo) models. The presented method generates its output by fusing the outputs of these different deep learning (DL) models.

Findings
The presented fusing approach significantly improves the detection accuracy of fire incidents in the input data.

Research limitations/implications
The computational complexity of the proposed method which is based on combining four different DL models is relatively higher than that of using each of these models individually. On the other hand, however, the performance of the proposed approach is considerably higher than that of any of the four DL models.

Practical implications
The simulation results show that using an ensemble model is quite useful for the precise detection of forest fires in real time through aerial vehicle videos or images.

Social implications
By this method, forest fires can be detected more efficiently and precisely. Because forests are crucial breathing resources of the earth and a shelter for many living creatures, the social impact of the method can be considered to be very high.

Originality/value
This study fuses the outputs of different DL models into an ensemble model. Hence, the ensemble model provides more potent and beneficial results than any of the single models.
A novel approach for construction disputes causal inferences based on empirical data: a case-controlled method combined with Bradford Hill criteria
Authors: Wang Peipei , Fenn Peter , Wang Kun 
Published: June 2023

PurposeThis paper aims to devise a case-controlled method combined with Bradford Hill criteria for causal inference of contractual disputes in construction projects. It is a genuine attempt in a systematic method from research design to execution for causal issues where only observational data is available.Design/methodology/approachThe authors located insufficient top management support as the putative pathogen of construction disputes based on a literature review, an interview and Delphi surveys. A questionnaire survey was then conducted to collect case-controlled data to ensure comparability, in which for each disputed project put in the experimental group, the authors sought for a dispute-free project of similar characteristics. The incidence rates of insufficient top management support in the experimental and control groups were then examined by Bradford Hill criteria as an alternative to the test of intervention effect.FindingsThe association of insufficient top management support and construction disputes was tested to conform with the Bradford Hill criteria with case-controlled data where applicable and logical deduction where statistical tests were not applicable. With a clear, positive, reasonable and statistically significant association, while excluding methodological biases, confounding and chance, the authors reached a causal verdict of insufficient top management support causing contractual disputes.Originality/valueThis paper supports the validity of applying a case-controlled method combined with Bradford Hill criteria in investigating causal issues in project management, especially the verdict of causal inference based on empirical data. In addition, the located root cause of contractual disputes could inform project management personnel with reasoned strategies for dispute avoidance.
The impact of discriminatory pricing based on customer risk: an empirical investigation using indirect lending through retail networks
Authors: Amaral Christopher , Kolsarici Ceren , Nediak Mikhail 
Published: June 2023

Purpose
The purpose of this study is to understand the profit implications of analytics-driven centralized discriminatory pricing at the headquarter level compared with sales force price delegation in the purchase of an aftermarket good through an indirect retail channel with symmetric information.

Design/methodology/approach
Using individual-level loan application and approval data from a North American financial institution and segment-level customer risk as the price discrimination criterion for the firm, the authors develop a three-stage model that accounts for the salesperson’s price decision within the limits of the latitude provided by the firm; the firm’s decision to approve or not approve a sales application; and the customer’s decision to accept or reject a sales offer conditional on the firm’s approval. Next, the authors compare the profitability of this sales force price delegation model to that of a segment-level centralized pricing model where agent incentives and consumer prices are simultaneously optimized using a quasi-Newton nonlinear optimization algorithm (i.e. Broyden–Fletcher–Goldfarb–Shanno algorithm).

Findings
The results suggest that implementation of analytics-driven centralized discriminatory pricing and optimal sales force incentives leads to double-digit lifts in firm profits. Moreover, the authors find that the high-risk customer segment is less price-sensitive and firms, upon leveraging this segment’s willingness to pay, not only improve their bottom-line but also allow these marginalized customers with traditionally low approval rates access to loans. This points out the important customer welfare implications of the findings.

Originality/value
Substantively, to the best of the authors’ knowledge, this paper is the first to empirically investigate the profitability of analytics-driven segment-level (i.e. discriminatory) centralized pricing compared with sales force price delegation in indirect retail channels (i.e. where agents are external to the firm and have access to competitor products), taking into account the decisions of the three key stakeholders of the process, namely, the consumer, the salesperson and the firm and simultaneously optimizing sales commission and centralized consumer price.

A pragmatic perspective on social entrepreneurial opportunities
Authors: Zettel Lauren , Garrett Robert 
Published: June 2023

PurposeScholars have applied a number of theoretical perspectives to enhance understanding of social entrepreneurial opportunities, and have most recently turned to the lens of critical realism. Although this metatheoretical perspective overcomes some problems with previous views and helps to identify the essence of a construct, the level of abstraction required by this approach leaves unanswered questions related to how social entrepreneurs leverage opportunities. The purpose of this paper is to create a framework to describe social entrepreneurial opportunities in a way that facilitates action and decision-making by social entrepreneurs.Design/methodology/approachThrough adapting Davidsson's (2015) deconstruction of the opportunity construct and using it to inform the pragmatist view of entrepreneurs as theory-testing scientists, this paper develops a framework for understanding social entrepreneurial opportunities. The paper explores the idea that social opportunities are composed of external enablers, a new social venture idea, and social opportunity confidence, and integrates the existing literature on social opportunities into this framework.FindingsUsing the framework developed, the authors advance a template of questions, hypotheses and quasi-experimental means that social entrepreneurs can use to determine how to move forward in social opportunity actualization. The authors also expand three categories of research questions that scholars may explore to extend the practical and theoretical understanding of social opportunities.Originality/valueThis work is among the first to adopt the pragmatist lens to elucidate social opportunities in a practical way. It takes an important first step in offering a means for social entrepreneurs to investigate when or where the requisite components of a social entrepreneurial opportunity may exist. Furthermore, it advances the pragmatist perspective of social opportunities by using Davidsson's model to explain the components of theories about what may or may not be a social opportunity.
Knowledge sharing enablers, processes, and innovation capability in a telecommunications company in an emerging market economy: a mixed-methods case study approach
Authors: Al-Shammari Minwir , Almulla Shaikha M. 
Published: June 2023

PurposeThis study aims to explore the interaction among individual factors (enjoyment in helping others and knowledge self-efficacy), organizational factors (top management support and organizational rewards) and the use of information and communication technology factors as enablers of knowledge-sharing (KS) processes (knowledge donating and knowledge collecting) and firm innovation capability (IC) in a telecommunications company in an emerging market economy, namely, Bahrain.Design/methodology/approachThe study used a mixed-methods case study approach. It used answers from 77 employees’ questionnaires and applied the partial least squares structural equation modeling method to test the research model. Several in-depth semidirective interviews were conducted with managers from different levels, functions and educational qualifications to address additional social, cultural, structural and strategic issues related to KS and IC.FindingsThe results indicated that enjoyment of helping others correlates with knowledge collection. Top management support had a substantial connection with knowledge donation, which had a robust positive relationship with firm IC. The interviews showed that moving toward a customer-centric strategy, policies, procedures and KS culture in a big organization with many business silos required tremendous effort and pain. People’s ability, willingness and readiness to share knowledge heavily depend on the corporate culture. Employee resistance to change posed a significant challenge.Originality/valueResearchers have rarely used a case study or a mixed-methods case study approach to explore KS and IC. This study aims to fill this gap using a mixed-methods approach to examine KS enablers, processes and IC in a developing country’s social and cultural context, Bahrain. The work brings together new ways of looking at things and figuring out what they mean to understand knowledge transfer and IC in a telecommunications company. The company must incur changes and additions to its KS mechanisms to inspire innovation.
Intellectual capital and performance of listed firms during the global financial crisis: the effects of legal origin
Authors: Akgün Ali İhsan , Türkoğlu Serap Pelin 
Published: June 2023

Purpose
This study aims to reveal to what extent successful European listed firms depend on their intellectual capital investment in achieving business success during the global financial crisis.

Design/methodology/approach
This study used value added intellectual coefficient (VAIC) methodology to measure the effect of intellectual capital on financial performance of business, which consist of 683 the sample listed firms. To examine the nexus between intellectual capital, legal origin and firm performance, estimated panel test and ordinary least squares regression model is used to data obtained from a sample of European countries.

Findings
The finding of this study suggests that there exists a positive relationship between intellectual capital and firm performance with return on assets (ROA) before the financial crisis, while firm performance with return on equity did not contribute to intellectual capital before and after the crisis period. Additionally, common law countries have a positive and statistically significant impact on firm performance with ROA for the before-crisis period, while code law countries have positively significant effect with VAIC on ROA.

Practical implications
The VAIC method has played a critical role in the management decision-making process to integrate the intellectual capital in the financial crisis period.

Originality/value
This study examines intellectual capital components such as human capital, structural capital and process capital efficiencies and firm performance in the legal origin context. The empirical evidence shows that there are significant impacts of legal origin on the nexus between intellectual capital and performance of listed firms during the global financial crisis.

IFRS 9, earnings management and capital management by European banks
Authors: Norouzpour Mohammadmahdi , Nikulin Egor , Downing Jeff 
Published: June 2023

PurposeThe purpose of this paper is to compare earnings management (EM) and capital management (CM) by European banks before and after the adoption of IFRS 9. After IFRS 9, banks have more discretion in recognizing loan-loss provisions than before IFRS 9. Hence, after IFRS 9, banks could use EM and CM to a greater extent.Design/methodology/approachThis paper analyzes a sample of European banks and uses regression analysis. First, this paper examines whether EM and CM changed after IFRS 9 was adopted. Next, this study examines whether any changes in EM and CM under IFRS 9 depend on regulatory quality (RQ) in the country where banks are located.FindingsThis paper has three results. First, after IFRS 9, EM increased relative to before IFRS 9. Second, after IFRS 9, CM increased relative to before IFRS 9. Third, this increase in EM was only for banks in countries with low RQ – in countries with high RQ, this study finds no change in EM after IFRS 9. Altogether, these results suggest that, first, EM and CM increased after IFRS 9 and, second, this increase in EM depended on the RQ of a bank’s country.Originality/valueThis paper identifies how the adoption of IFRS 9 affected EM and CM by European banks. The main contribution of this paper is that it examines the impact of the adoption of IFRS 9 on EM and CM by European banks using data from banks’ actual financial statements.
