Abstract

Purpose

Fraud transaction detection has become a significant factor in the communication technologies and electronic commerce systems, as it affects the usage of electronic payment. Even though, various fraud detection methods are developed, enhancing the performance of electronic payment by detecting the fraudsters results in a great challenge in the bank transaction.

Design/methodology/approach

This paper aims to design the fraud detection mechanism using the proposed Harris water optimization-based deep recurrent neural network (HWO-based deep RNN). The proposed fraud detection strategy includes three different phases, namely, pre-processing, feature selection and fraud detection. Initially, the input transactional data is subjected to the pre-processing phase, where the data is pre-processed using the Box-Cox transformation to remove the redundant and noise values from data. The pre-processed data is passed to the feature selection phase, where the essential and the suitable features are selected using the wrapper model. The selected feature makes the classifier to perform better detection performance. Finally, the selected features are fed to the detection phase, where the deep recurrent neural network classifier is used to achieve the fraud detection process such that the training process of the classifier is done by the proposed Harris water optimization algorithm, which is the integration of water wave optimization and Harris hawks optimization.

Findings

Moreover, the proposed HWO-based deep RNN obtained better performance in terms of the metrics, such as accuracy, sensitivity and specificity with the values of 0.9192, 0.7642 and 0.9943.

Originality/value

An effective fraud detection method named HWO-based deep RNN is designed to detect the frauds in the bank transaction. The optimal features selected using the wrapper model enable the classifier to find fraudulent activities more efficiently. However, the accurate detection result is evaluated through the optimization model based on the fitness measure such that the function with the minimal error value is declared as the best solution, as it yields better detection results.

Abstract

Purpose

This paper reviews the literature on internationalization barriers of small and medium enterprises (SMEs) from developing countries. The purposes of the study are: (1) to explicitly point out specific factors influencing the growth and internationalization of SMEs from developing countries and (2) to identify the research gaps to provide lucid and succinct directions for future research in this area.

Design/methodology/approach

The authors selected relevant papers from journals listed on Web of Science and Scopus databases.

Findings

It was found that there are large number of questions remain unanswered regarding the internationalization of SMEs from developing countries regarding the factors determining their growth and internationalization.

Originality/value

This review distinctively accentuates previous studies on such barriers influencing the growth of SMEs from developing countries and systematically synthesize the issues faced by those SMEs. Thus, the authors seek to provide a comprehensible platform for researchers working in this area.

Abstract

Purpose

Today, the employees stand firm as an integral part of the organization and are a precious asset. They are willing to learn, accept challenges and strive hard to deliver their level best. The role of the employees has become pronounced and significant, and it is no more conventional. They are now taking up responsibilities in strategic planning and development of the organization. Thus, HR department plays a profuse role in planning for the human resource of the firm to optimize the utilization of their potentials that would help support and meet the business as well as strategic goal of the firm. These HR planning programs ensure managing people within a planned framework and make them develop their performance that becomes a source of sustained competitive advantage for the firm. The paper aims to discuss these issues.

Design/methodology/approach

A descriptive research has been conducted with cross-sectional survey through a formalized questionnaire. Multistage sampling has been used in the study. Primary data have been collected from different manufacturing industries of India. Exploratory factor analysis and confirmatory factor analysis have been conducted on the hypothesized research model. Structural equation modeling has been done to specify the relation between the measured and latent variables.

Findings

The HR planning programs, namely, staffing plan and succession plan, yield a better result in addressing the strategic goal of the company. Succession plan, staffing plan and talent management strategies augment the efficacious performance of the firm. Effectual performance aids in gaining a competitive advantage for the firm in a substantial way. Job analysis and design have no impact in achieving the strategic intent of the organization.

Originality/value

The study gives a comprehensive scenario of the HR planning programs that can help the organization to meet and uphold their strategic goals. The study provides a model that can solidify and bind the organization toward securing organizational intent and leading a steadfast business process in this dynamic competitive marketplace.

Abstract

Purpose

This study aims to synthesize two different benzoxazines (Bz) monomers using bio-based and petroleum-based primary amines, respectively, and they have been compared to study their thermal and mechanical performances.

Design/methodology/approach

A bio-based bisphenol, Divanillin (DiVa), was formed by reacting two moles of vanillin with one mole of ethylenediamine (EDA) which was then reacted firstly with paraformaldehyde and EDA to form the benzoxazine DiVa-EDA-Bz, and secondly with paraformaldehyde and furfuryl amine (FFA) to form the benzoxazine DiVa-FFA-Bz. The molecular structure and thermal properties of the benzoxazines were characterized by fourier transform infrared spectroscopy and nuclear magnetic resonance (1H,13C) spectroscopies, differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA), respectively. The benzoxazines were further coated on mild steel panels to evaluate their mechanical properties and chemical resistance.

Findings

The DSC results of DiVa-FFA-Bz showed two exothermic peaks related to crosslinking compared to the one in DiVa-EDA-Bz. The DiVa-FFA-Bz also showed a higher heat of polymerization than DiVa-EDA-Bz. The TGA results showed that DiVa-FFA-Bz exhibited higher thermal stability with a residual char of 54.10% than 43.24% for DiVa-EDA-Bz. The chemical resistance test results showed that DiVa-FFA-Bz showed better chemical resistance and mechanical properties due to its higher crosslinking density.

Originality/value

This study shows the use of bio-based materials, vanillin and FFA, for synthesizing a benzoxazine resin and its application at high temperatures.

Abstract

The case on Moodcafe captures the journey of the start-up and its entrepreneurs from the beginning till the fund-raising stage. The case brings forth critical decisions that each entrepreneur or the team of co-founders have to address during their start-up journey. This short case gives opportunity to delve into two aspects mainly a) As a founder, which investor should one choose for seeking funds and what should be the terms and conditions of investment? and b) How can one review and assess the business model of a start-up?
