Abstract
Purpose
This paper aims to propose and analyse a two-prey–one-predator system with mixed functional response.
Design/methodology/approach
The predator exhibits Holling type IV functional response to one prey and Holling type I response to other. The occurrence of various positive equilibrium points with feasibility conditions are determined. The local and global stability of interior equilibrium points are examined. The boundedness of system is analysed. The sufficient conditions for persistence of the system is obtained by using Bendixson–Dulac criteria. Numerical simulations are carried out to illustrate the analytical findings.
Findings
The authors have derived the local and global stability condition of interior equilibrium of the system.
Originality/value
The authors observe that the critical values of some system parameter undergo Hopf bifurcation around some selective equilibrium. Hence, numerical simulations reveal the condition for the system to be stable and oscillatory.

Abstract
Purpose
Phishing is one of the major threats affecting businesses worldwide in current times. Organizations and customers face the hazards arising out of phishing attacks because of anonymous access to vulnerable details. Such attacks often result in substantial financial losses. Thus, there is a need for effective intrusion detection techniques to identify and possibly nullify the effects of phishing. Classifying phishing and non-phishing web content is a critical task in information security protocols, and full-proof mechanisms have yet to be implemented in practice. The purpose of the current study is to present an ensemble machine learning model for classifying phishing websites.
Design/methodology/approach
A publicly available data set comprising 10,068 instances of phishing and legitimate websites was used to build the classifier model. Feature extraction was performed by deploying a group of methods, and relevant features extracted were used for building the model. A twofold ensemble learner was developed by integrating results from random forest (RF) classifier, fed into a feedforward neural network (NN). Performance of the ensemble classifier was validated using k-fold cross-validation. The twofold ensemble learner was implemented as a user-friendly, interactive decision support system for classifying websites as phishing or legitimate ones.
Findings
Experimental simulations were performed to access and compare the performance of the ensemble classifiers. The statistical tests estimated that RF_NN model gave superior performance with an accuracy of 93.41 per cent and minimal mean squared error of 0.000026.
Research limitations/implications
The research data set used in this study is publically available and easy to analyze. Comparative analysis with other real-time data sets of recent origin must be performed to ensure generalization of the model against various security breaches. Different variants of phishing threats must be detected rather than focusing particularly toward phishing website detection.
Originality/value
The twofold ensemble model is not applied for classification of phishing websites in any previous studies as per the knowledge of authors.

Abstract
Purpose
A maturity model for Industry 4.0 (I4.0 MM) with influencing factors is designed to address maturity issues in adopting Industry 4.0. Standardisation in I4.0 supports manufacturing industry transformation, forming reference architecture models (RAMs). This paper aligns key factors and maturity levels in I4.0 MMs with reputable I4.0 RAMs to enhance strategy for I4.0 transformation and implementation.
Design/methodology/approach
Three steps of alignment consist of the systematic literature review (SLR) method to study the current published high-quality I4.0 MMs, the taxonomy development of I4.0 influencing factors by adapting and implementing the categorisation of system theories and aligning I4.0 MMs with RAMs.
Findings
The study discovered that different I4.0 MMs lead to varied organisational interpretations. Challenges and insights arise when aligning I4.0 MMs with RAMs. Aligning MM levels with RAM stages is a crucial milestone in the journey toward I4.0 transformation. Evidence indicates that I4.0 MMs and RAMs often overlook the cultural domain.
Research limitations/implications
Findings contribute to the literature on aligning capabilities with implementation strategies while employing I4.0 MMs and RAMs. We use five RAMs (RAMI4.0, NIST-SME, IMSA, IVRA and IIRA), and as a common limitation in SLR, there could be a subjective bias in reading and selecting literature.
Practical implications
To fully leverage the capabilities of RAMs as part of the I4.0 implementation strategy, companies should initiate the process by undertaking a thorough needs assessment using I4.0 MMs.
Originality/value
The novelty of this paper lies in being the first to examine the alignment of I4.0 MMs with established RAMs. It offers valuable insights for improving I4.0 implementation strategies, especially for companies using both MMs and RAMs in their transformation efforts.

Abstract
Purpose
This research is based on a theoretical interest and practical need to examine female actors as entrepreneurs and innovators. The Saudi Vision 2030 emphasizes entrepreneurship, innovation and stronger female participation in the work force. The purpose of this paper is to point to theoretical underpinnings in female entrepreneurial and innovative activity and to examine success factors for female entrepreneurial innovators in the context of the Kingdom of Saudi Arabia (KSA).
Design/methodology/approach
The paper is based on secondary data sources. The secondary data in this research were collected from recent academic journals related to female innovation and entrepreneurship. The selected literature represents international and regional (Middle Eastern) research, including research addressing KSA.
Findings
Theories are not universal but contextually bound, and Western theories may not directly apply to the KSA context. The late female labor history and gender segregation have not formed an environment similar to the West where innovation has a male connotation and where gender is created or recreated in interaction. The paper suggests gender differences and similarities in innovation as a suitable approach to examine female entrepreneurs and innovators in KSA. While there are similar tendencies between the Saudi and international contexts in regard success factors, KSA inhibits unique factors associated with female entrepreneurs and innovators and their environment.
Research limitations/implications
This research is aimed at academia and offers points to consider for theoretical examination, focusing on the fitness of theory from an economic, social and cultural perspectives. The research may offer knowledge to policymakers and practitioners in the Middle East region and KSA when applying new policies on entrepreneurship and innovation.
Originality/value
The value of the research lies in its timeliness. While there are economic rationales for research on female entrepreneurial innovators, there are theory-related reasons to examine the topic. With the increased interest in research on Saudi female entrepreneurs, academic discussion needs to take a closer look at the context to gain an understanding of how theoretical approaches may or may not transfer across regions.

Abstract
Purpose
Diagnosing genetic neuromuscular disorder such as muscular dystrophy is complicated when the imperfection occurs while splicing. This paper aims in predicting the type of muscular dystrophy from the gene sequences by extracting the well-defined descriptors related to splicing mutations. An automatic model is built to classify the disease through pattern recognition techniques coded in python using scikit-learn framework.
Design/methodology/approach
In this paper, the cloned gene sequences are synthesized based on the mutation position and its location on the chromosome by using the positional cloning approach. For instance, in the human gene mutational database (HGMD), the mutational information for splicing mutation is specified as IVS1-5 T > G indicates (IVS - intervening sequence or introns), first intron and five nucleotides before the consensus intron site AG, where the variant occurs in nucleotide G altered to T. IVS (+ve) denotes forward strand 3′– positive numbers from G of donor site invariant and IVS (−ve) denotes backward strand 5′ – negative numbers starting from G of acceptor site. The key idea in this paper is to spot out discriminative descriptors from diseased gene sequences based on splicing variants and to provide an effective machine learning solution for predicting the type of muscular dystrophy disease with the splicing mutations. Multi-class classification is worked out through data modeling of gene sequences. The synthetic mutational gene sequences are created, as the diseased gene sequences are not readily obtainable for this intricate disease. Positional cloning approach supports in generating disease gene sequences based on mutational information acquired from HGMD. SNP-, gene- and exon-based discriminative features are identified and used to train the model. An eminent muscular dystrophy disease prediction model is built using supervised learning techniques in scikit-learn environment. The data frame is built with the extracted features as numpy array. The data are normalized by transforming the feature values into the range between 0 and 1 aid in scaling the input attributes for a model. Naïve Bayes, decision tree, K-nearest neighbor and SVM learned models are developed using python library framework in scikit-learn.
Findings
To the best knowledge of authors, this is the foremost pattern recognition model, to classify muscular dystrophy disease pertaining to splicing mutations. Certain essential SNP-, gene- and exon-based descriptors related to splicing mutations are proposed and extracted from the cloned gene sequences. An eminent model is built using statistical learning technique through scikit-learn in the anaconda framework. This paper also deliberates the results of statistical learning carried out with the same set of gene sequences with synonymous and non-synonymous mutational descriptors.
Research limitations/implications
The data frame is built with the Numpy array. Normalizing the data by transforming the feature values into the range between 0 and 1 aid in scaling the input attributes for a model. Naïve Bayes, decision tree, K-nearest neighbor and SVM learned models are developed using python library framework in scikit-learn. While learning the SVM model, the cost, gamma and kernel parameters are tuned to attain good results. Scoring parameters of the classifiers are evaluated using tenfold cross-validation using metric functions of scikit-learn library. Results of the disease identification model based on non-synonymous, synonymous and splicing mutations were analyzed.
Practical implications
Certain essential SNP-, gene- and exon-based descriptors related to splicing mutations are proposed and extracted from the cloned gene sequences. An eminent model is built using statistical learning technique through scikit-learn in the anaconda framework. The performance of the classifiers are increased by using different estimators from the scikit-learn library. Several types of mutations such as missense, non-sense and silent mutations are also considered to build models through statistical learning technique and their results are analyzed.
Originality/value
To the best knowledge of authors, this is the foremost pattern recognition model, to classify muscular dystrophy disease pertaining to splicing mutations.

Abstract
Purpose
The purpose of this paper is to pay tribute to several of the ideas of Jan‐Erik Gröjer by reviewing and critiquing the field of Human Competence Accounting (HCA) since his Accounting, Auditing & Accountability Journal review article in 1998.Three research questions he posed in that article are now addressed in the current paper: What could be done, as envisaged in the commentary of Gröjer and Johanson; What has been published in HCA research in the ten year period (1999‐2008); What more could/should be done in HCA as a research agenda.
Design/methodology/approach
A literature based analysis and critique of HCA accounting articles published in the selected journals from 1999 to 2008 is employed. A purpose built coding and classification scheme is built around several categories for the purpose of analysing the HCA literature.
Findings
The paper seeks to demonstrate the importance of Gröjer and Johanson's review and indicates that questions they raised and possible research directions have been acted upon by a number of authors. The findings of the analysis indicate that, a decade on from the original review, HCA is a legitimate area for accounting research and is multi‐disciplinary and multi‐focused in nature.
Research limitations/implications
The paper only considers selected HCA articles within the ten journals used over the period 1999‐2008.American mainstream positivist research has not been reviewed. Also the categories chosen to represent HCA have several limitations which are addressed in the paper.
Originality/value
HCA research has a strong tradition and the Gröjer and Johanson review is an important beacon that provided insights to accounting researchers. The current analysis extends Jan‐Erik's work by providing several insights into what has happened and also provides several ideas for future research and policy work in accounting for HCA.
