Abstract

Purpose

To empirically study the direct and mediating relationships between blockchain technology adoption strategy (BCTAS), electronic supply chain management diffusion (eSCMD), entrepreneurial orientation (EO) and human resources information system (HRIS) in Egyptian banks. This paper aims to connect the dots and show the relationships linking these related constructs after the emergence of this breakthrough blockchain technology.

Design/methodology/approach

The authors have undertaken a thematic review of relevant multidisciplinary business management literature and then developed a conceptual model. This model was examined through adopting a mixed-methods approach, through which 300 quantitative questionnaires were filled by information technology (IT) staff at 12 banks in Egypt utilising a snowball sample. Besides, 20 qualitative interviews were carried out with international and Egyptian blockchain experts for exploratory and explanatory purposes. The suggested hypotheses were tested using structural equation modelling.

Findings

The results revealed that EO affects positively and significantly BCTAS and HRIS. BCTAS affects positively and significantly both HRIS and eSCMD. Concerning the linkage between external/supply chain and internal/organisational information diffusion, HRIS has a positive and significant effect on eSCMD. The direct EO–eSCMD relationship is not supported. Yet, indirectly, BCTAS mediates significantly EO–eSCMD and EO–HRIS relationships. Further, HRIS mediates significantly the indirect BCTAS–eSCMD relationship.

Practical implications

The findings of this research shed light on the benefits and challenges of adopting BCTAS within emerging markets in general and Egyptian banking in specific, which can support an effective and efficient decision-making process undertaken by strategic and functional banking managers with EO in similar emerging economies.

Originality/value

Conceptually and empirically, it is the first article that investigated direct and mediating EO–BCTAS–HRIS–eSCMD relationships in a promising banking industry of an emerging market. It solved an interdisciplinary research puzzle by piecing together the relevant contemporary literature on production, operations and SC management, entrepreneurship, HR management and strategic technology adoption.

Abstract

Purpose

The purpose of this study is to examine how well reinforced concrete structures can be shielded against concrete carbonation using anti-carbonation coatings based on synthetic polymer.

Design/methodology/approach

Applying free radical polymerization, an acrylate terpolymer emulsion that a surfactant had stabilized was created. A thermogravimetric analysis, minimum film-forming temperature, Fourier transform infrared spectroscopy and particle size distribution are used to characterize the prepared eco-friendly water base acrylate terpolymer emulsion. Using three different percentages of the acrylate terpolymer emulsion produced, 35%, 45% and 55%, the anti-carbonation coating was formed. Tensile strength, tensile strain, elongation, crack-bridging ability, carbon dioxide permeability, chloride ion diffusion, average pull-off adhesion strength, water vapor transmission, gloss, wet scrub resistance, QUV/weathering and storage stability are the characteristics of the anti-carbonation coating.

Findings

The formulated acrylate terpolymer emulsion enhances anti-carbonation coating performance in CO2 permeability, Cl-diffusion, crack bridging, pull-off adhesion strength and water vapor transmission. The formed coating based on the formulated acrylate terpolymer emulsion performed better than its commercial counterpart.

Practical implications

To protect the steel embedded in concrete from corrosion and increase the life span of concrete, the surface of cement is treated with an anti-carbonation coating based on synthetic acrylate terpolymer emulsion.

Social implications

In addition to saving lives from building collapse, it maintains the infrastructure for the long run.

Originality/value

The anti-carbonation coating, which is based on the synthetic acrylate terpolymer emulsion, is environmentally benign and stops the entry of carbon dioxide and chlorides, which are the main causes of steel corrosion in concrete.

Abstract

Purpose

This study aims to extend the pot life without altering the qualities and performance of the coating, which is important to increase when manufacturing polyurethane coatings.

Design/methodology/approach

An acrylic polyol from a mixture of different monomers of hydroxypropyl methacrylate, methacrylic acid, 2-ethylhexyl acrylate, methyl methacrylate and n-butyl methacrylate was prepared with different ratios of 2,4-pentanedione as a pot life extender. The reaction takes place in presence of di-tert-butyl peroxide as initiator with samples (T1–T7). The physical properties of prepared acrylic polyol were characterized. Then, coating polyurethane varnish was prepared from the prepared acrylic polyol with an aliphatic polyisocyanate in a 1:1 equivalent ratio of OH:NCO at room temperature, in presence of paint thinner (diluents/solvent) and dibutyltin dilaurate as a catalyst to give samples (T1C–T7C). This coating was evaluated via Fourier-transform infrared spectroscopy, drying time, hardness and gloss, distinctness of image and reflected image quality.

Findings

The coating has a prolonged pot life while still maintaining the other qualities, thanks to the greater 2,4-pentanedione content.

Originality/value

It is desired to have a paint which has a satisfactory pot life, short curing time and reduces many drawbacks such as inefficient working and deterioration of the paint before application.

Abstract

Purpose

The purpose of this study is to investigate conceptually and empirically the direct and indirect relationships between university social responsibility (USR), university social innovation strategy (USIS) in terms of social awareness (SA), intention for social innovation (ISI), organisational structure for social innovation (SSI) and innovativeness in social value creation (ISVC) and gaining a sustainable competitive advantage (SCA) at quality-accredited faculties of an emerging market.

Design/methodology/approach

A conceptual model was presented and a mixed-methods approach was exploited to fill a research gap detected in strategic corporate social innovation literature. The authors formed a data collection team that contacted all the quality-accredited public and private/international faculties, of which 109 faculties in 11 Egyptian governorates responded and their quality units filled questionnaires that were analysed by structural equation modelling. For comprehensive understanding, qualitative interviews were set to gather data from managers/leaders and teaching staff working at those faculties in quality management and community engagement practices as well as students.

Findings

Results demonstrated that USR positively and significantly influenced SCA and USIS. Further, USIS (in terms of ISI, SSI and ISVC) positively and significantly influenced SCA. However, USIS (in terms of SA) had a positive yet insignificant influence on SCA. Indirectly, USIS was found to be partially mediating USR–SCA relationship.

Practical implications

University leaders/staff can gain insights on how to adopt differentiation strategies, which enable their institutions to shift from being just socially responsible to becoming socially innovative by presenting solutions to social, economic, cultural, environmental and health-care problems/challenges within their communities in general and during pandemics. This can be sustained through developing innovative quality-based processes/programmes/services related to education, research and community outreach that better serve social needs to be quality-accredited and unique over their rivals.

Social implications

Satisfying social needs through promoting innovative processes/services can reinforce a favourable social change.

Originality/value

From a cross-disciplinary perspective, the authors interwove conceptually sparse literature of strategic, operations, knowledge capacity and innovation management that studied university social innovation research area. Also, to the best of the authors’ knowledge, this is the first research that examined empirically USR–USIS–SCA relationships of quality-accredited faculties in an emerging economy during Covid-19 pandemic.

Abstract

Purpose

This paper aims to study the impact of innovation climate (IC) on co-creating modular mass-customisation (CMMC) in terms of cost effectiveness, volume effectiveness, responsiveness, product modularity and collaborative assembly. Additionally, this research paper investigates the effect of IC and CMMC on the value to customer (VC) in a modular jewellery emerging market that includes international companies.

Design/methodology/approach

After conducting a comprehensive literature review, the authors suggested a conceptual framework and examined it using mixed methods approach. In addition to qualitative focus groups, questionnaires were filled – across five-point Likert scale format – through 63 depth interviews carried out with subject-matter-experts working at 14 international organisations in the Egyptian modular jewellery market. SmartPLS software was used for structural equation modelling analysis.

Findings

Results showed that CMMC positively and significantly affects VC. Furthermore, IC positively and significantly affects both CMMC and VC.

Practical implications

Recent industrial developments that can be observed in such international modular jewellery sector can be enhanced by the empirical evidence of this research regarding the importance of developing IC for more creative manufacturing approach of modular mass-customisation and better VC.

Originality/value

To the best of our knowledge, it is the first empirical study that investigates the relationship between CMMC, IC and VC in a unique jewellery market, which recently generated high customer involvement in the assembly/reassembly processes. Conceptually and empirically, it consolidates and adds to the literature of production and operations management (mass-customisation), organisational studies and innovation science (organisational climate for innovation) and applied social sciences.

Abstract

Purpose

The purpose of this research paper is to study the relationship between entrepreneurial marketing strategy (EMS), institutional environment (IE) and business performance (BP). Further, it examines the role of gender and entrepreneurial experience (EE) as moderators of EMS-BP and IE-BP relationships.

Design/methodology/approach

Based on the literature review, the authors proposed a conceptual model that was tested using a quantitative approach. Questionnaires were filled by 202 owners/entrepreneurs of small- and medium-sized enterprises (SMEs) in Egypt. Because of the absence of a formal population-frame for the Egyptian SMEs, non-probability quota sampling technique was used that considered differences in gender and EE. SmartPLS software was used for data analysis.

Findings

The results indicated that EMS has significant positive effect on BP. IE has significant positive effect on EMS but insignificant effect on BP. Gender was found to be moderating significantly both the EMS-BP and IE-BP relationships. However, EE was found to be an insignificant moderator in the EMS-BP relationship.

Practical implications

The findings communicate insights to the SMEs on the importance of undertaking proactive, risk-taking and innovative activities while creating and delivering value to their customers. Also, it encapsulates further implications for policymakers to promote a better IE for entrepreneurship in Egypt.

Originality/value

This study contributes conceptually to the interdisciplinary research that investigated the integration between entrepreneurship and marketing as a successful functional strategy in SMEs and its effect on enhancing BP and market share. Empirically, it adds value to the available literature on contemporary strategic entrepreneurship by analysing these IE-EMS-EE-Gender-BP relationships in a promising, yet under-researched, transitional economy.

Abstract

Purpose

This study aims to explore the incorporation of starch nanoparticles (SNPs) in cross-linking formulation of cotton fabrics to see their impact on fabric performance like tensile strength, dry wrinkle recovery angles, elongation at break, degree of whiteness and increase in weight as well as durability.

Design/methodology/approach

SNPs of size around 80-100 nm were successfully prepared from native maize starch by Nano precipitation technique and confirmed instrumentally by scanning electron microscope (SEM), transmittance electron microscope (TEM), Fourier transformer infrared (FTIR) spectroscopy and particle size analyzer. The latter were incorporated in cross-linking formulation of cotton fabrics encompassing different concentrations of citric acid and sodium hypophosphite at different curing time and temperature in 100 ml distilled water to a wet pickup of ca. 85 per cent. The fabric samples were dried for 3 min at 85°C and cured at specified temperatures for a specified time intervals in thermo fixing oven according to pad-dry-cure method.

Findings

FTIR spectra and SEM micrograph signified the chemical structure and surface morphology of cotton fabric before and after finishing in absence and presence of SNPs. Cotton fabric samples finished in presence of SNPs showed a higher tensile strength, elongation at break, comparable dry wrinkle recovery angles and degree of whiteness than that finished in their absence. On the other hand, the enhancement in the aforementioned performance reflects the positive impact of incorporation of SNPs in textile finishing especially with strength properties; which are one of the important requirements for industrial fabrics that can be used widely in heavy-duty applications.

Research limitations/implications

SNPs with its booming effect with respect to biodegradability, reactivity and higher surface area can be used as a novel reinforcement permanent finish for cotton fabrics instead of more hazardous materials likes poly acrylate and monomeric compounds.

Practical implications

As SNPs biopolymers is one of the important reinforcement agents, so it was expected that it would minimize the great loss in strength properties during easy-care cotton finishing and improve the fabric performance.

Originality/value

The novelty addressed here is undertaken with a view to remediate some of the serious defects of easy-care cotton fabrics using poly carboxylic acids; especially with the great loss in strength properties by virtue of using SNPs as a permanent finish. Besides, to the authors’ knowledge, there is no published work so far concerning the use of SNPs as an innovative base for production of easy-care finished cotton textiles with high performance.

Abstract

Organizations in many domains generate a considerable amount of heterogeneous data every day. Such data can be processed to enhance these organizations’ decisions in real time. However, storing and processing large and varied datasets (known as big data) is challenging to do in real time. In machine learning, streaming feature selection has always been considered a superior technique for selecting the relevant subset features from highly dimensional data and thus reducing learning complexity. In the relevant literature, streaming feature selection refers to the features that arrive consecutively over time; despite a lack of exact figure on the number of features, numbers of instances are well-established. Many scholars in the field have proposed streaming-feature-selection algorithms in attempts to find the proper solution to this problem. This paper presents an exhaustive and methodological introduction of these techniques. This study provides a review of the traditional feature-selection algorithms and then scrutinizes the current algorithms that use streaming feature selection to determine their strengths and weaknesses. The survey also sheds light on the ongoing challenges in big-data research.

Abstract

Purpose

The purpose of this study is to propose an analytical model that investigates both a direct path between corporate governance quality and earnings quality and an indirect path, in which firms' performance is a mediating variable that is influenced by corporate governance quality and that, in turn, influences earnings quality.

Design/methodology/approach

The study employs a structural equation modelling (SEM), to a sample of Egyptian listed firms during 2011–2017, to test the proposed analytical model and to determine the relative importance of both the direct and indirect paths.

Findings

The findings show a statistically significant evidence of both a direct path from corporate governance quality to earnings quality, and an indirect path that is mediated by firms' performance, suggesting that both corporate governance quality and performance have a complementary effect on earnings quality. However, the weight of the evidence favouring the direct path is more important in case of accounting-based performance measures; and the weight of the evidence favouring the indirect path is more important in case of market-based performance measures.

Research limitations/implications

The current study has some limitations. First, the study focuses specifically on one proxy for measuring earnings quality which is the absolute value of discretionary accruals. Other proxies of earnings quality could be examined in future research, such as income smoothing, earnings persistence and timely loss recognition. Another limitation is that only financial performance measures were examined, namely, return on assets, return on equity, price-to-earnings ratio and market-to-book value. Notwithstanding, non-financial performance measures could be investigated in future studies, such as balanced scorecard (BSC). Furthermore, considering cultural, political and legislative differences among countries, the results may not be generalised outside the scope of the current sample (i.e. Egyptian listed firms).

Practical implications

The implications of the findings for both theory and practice are discussed.

Originality/value

This study is distinguished by validating an analytical model that has been overlooked by prior studies. Moreover, it provides a new constructed index for measuring corporate governance quality. Furthermore, it uses a new sophisticated statistical technique, which is SEM, for testing the proposed model.

Abstract

Purpose

This study aims to explore the application of the theory of planned behavior (TPB) in understanding Muslim consumers’ visitation motives to halal hotels. The model tests the impact of additional factors to the TPB such as religious commitment, religious-identification and information seeking behavior on consumers’ attitudes and intentions to visit Halal hotels.

Design/methodology/approach

Survey data was collected from 183 respondents to examine the relationships between these factors and customers’ intention to visit halal hotels. The survey participants were selected from diverse backgrounds to ensure a representative sample. Structural equation modeling was used to assess the conceptual model.

Findings

This study highlights the significance of attitudes shaped by subjective norms and information seeking behavior, emphasizing their influence on consumers’ inclination to visit halal hotels. In addition, the role of religious commitment is examined, shedding light on the impact of individuals’ strong faith in shaping their attitudes and behaviors toward halal hotels.

Originality/value

These results contribute to the existing literature on Halal consumer behavior and provide practical implications for professionals and policymakers in the hospitality industry. Understanding the factors that influence customers’ intentions to visit halal hotels can assist in developing tailored marketing strategies and creating an inclusive environment.
