Abstract
Purpose
The purpose of this paper is to introduce a closed-form analytical solution to evaluate the nominal moment capacity and associated deflections of steel-FRP beam systems. The proposed solution takes into consideration the partial composite behavior resulting from the interfacial contact and slip between the subcomponents of the system.
Design/methodology/approach
The partial composite action theory was used to develop an elastic analytical solution for the deflection of simply supported composite steel-FRP beams subjected to a mid-span point load. The solution takes into consideration the partial composite behavior of the system that arises from the interlayer slip at the steel-FRP interface.
Findings
The developed analytical model is used to predict the nominal moment capacity of the composite beam and the load value at the onset of yielding in the steel subcomponent of the section. The distribution of shear forces induced in the steel fasteners due to the interfacial slip is also obtained analytically. A comparative study is conducted by comparing the analytical results to their counterparts resulting from finite element modeling of the composite steel-FRP system. The agreement between analytical results and finite element predictions validates the accuracy of the derived analytical solution for partial composite steel-FRP beams.
Research limitations/implications
The proposed solution applies only to the FRP strips and 6 mm steel bolts used in the study.
Originality/value
Recent studies revealed a promising efficiency of using mechanically fastened hybrid FRP sheets in strengthening steel beams. A major advantage of this technique is the ductile behavior of the steel-FRP system. The current paper introduces a closed-form analytical solution to evaluate the nominal moment capacity and associated deflections of steel-FRP beam systems. Forces developed at the steel-FRP interface due to the relative slip between both components are considered in the proposed analytical solution.

Abstract
Despite discussions of the increasingly global character of information systems (IS), IS research remains highly “Western‐centric” both in terms of its subjects of study and the nationalities of the authors. Researchers interested in IS in non‐Western settings are thus reliant on a fragmented and not easily accessible literature that presents a potentially distorted picture of IS practice in these regions. This paper explores this situation through an examination of the literature relating to IS in Egypt (both directly, but also as a Middle Eastern, Arab or Islamic country). A macro analysis of these studies indicates that they are predominantly positivistic in epistemology, quantitative in methodology and focused on economic development and national culture. Although many of the studies make comparisons with other countries in the region, the explicit, or sometimes implicit, point of reference is almost invariably with “the West”. This is repeated in a detailed analysis of individual studies. Implications of these findings for research on IS in non‐Western settings are discussed.

Abstract
Purpose
In this paper, two promising corrosion inhibitors based on natural and eco-friendly materials such as peanut fatty acids (PFA) were prepared and challenged with a common efficient commercial inhibitor. Two amino derivatives based on aliphatic and aromatic compounds such as 2-amino-2-methyl-1-propanol (AMP) and 2-amino-2-phenyl-1-propanol (APP), respectively, were used and reacted with PFA under controlled conditions to produce the corrosion inhibitors. The prepared inhibitors, namely, PFA-AMP (inhІ) and PFA-APP (inhІІ), were confirmed and characterized by Fourier transfer infrared spectroscopy, acid value determination and viscosity measurements.
Design/methodology/approach
First, different coating formulations free from any inhibitors were prepared and irradiated under different doses of electron beam source to select the best dose. Several concentrations of synthesized anticorrosion materials were then added to coating formulations to estimate them as anticorrosion materials for mild steel panels. Then, all formulations were coated and polymerized at a dose of 10 kGy. The corrosion tests, weight loss and water uptake were studied for all films after immersion in 3.5% sodium chloride. Moreover, the chemical and physico-mechanical properties were determined for all films.
Findings
The results exhibited that the different concentrations of two inhibitors did not show any significant change on the different properties of all films, and the best concentration, which gives the better protection for steel panels, was to be 1.0 g for two inhibitors.
Originality/value
It was found that the protection efficiency of the inhІ is better and higher than that of the inhІІ and also of the commercial inhibitor with the following order: inhІ > commercial inhibitor > inhІІ.

Abstract
Purpose
This study aims to investigate the impact of managerial power distance on the corporate sustainability performance of Chinese firms and to explore the regulatory role of corporate digitalization in the Chinese capital market.
Design/methodology/approach
The study collects data from 2,632 A-share Chinese non-financial firms listed on Shanghai and Shenzhen stock exchanges during the period from 2010 to 2020. The authors apply different panel data regression techniques (fixed effects, GMM-System) to investigate the impact of managerial power distance on corporate sustainability performance and to explore the regulatory role of corporate digitalization in the Chinese capital market.
Findings
The results of the study show a positive relationship between high managerial power distance and the sustainability performance of Chinese non-financial firms. This positive relationship is particularly pronounced in Chinese state-owned enterprises (SOEs). The results also show that corporate digitalization increases the sustainability performance of Chinese firms. Further, corporate digitalization weakens the positive relationship between high-power distance and the sustainability performance of Chinese firms. These results are robust to alternate sustainability performance measures and various regression techniques.
Originality/value
To the best of the authors' knowledge, this is the first study that investigates the regulating impact of corporate digitalization on the relationship between managerial power distance and corporate sustainability performance in China.

Abstract
Purpose
The purpose of this study is to examine consumer attitude toward gamification in the context of over-the-top (OTT) media service. The particular focus of this paper is on game mechanics from the mechanics-dynamics-aesthetics framework and its effects on consumer attitude toward both gamification and OTT media service provider brand.
Design/methodology/approach
A 2 × 2 × 2 between-subjects factorial experiment to examine the three core elements of game mechanics – components, controls and courses on consumer attitude, which was operationalized in eight vignettes with a sample size of 296.
Findings
It was found that the three elements in game mechanics demonstrated a multiplicative effect. The different combinations of elements in game mechanics would result in eliciting different consumer attitudes toward gamification and brand. Despite one combination that attained a high positive consumer attitude toward gamification in OTT, that same combination was not effective in creating a high positive attitude toward the OTT provider brand. The findings demonstrate the need for OTT providers to be clear of their gamification objectives before selecting the combination of game mechanics.
Research limitations/implications
This study adds to the body of knowledge on consumer attitude toward gamification, especially in the OTT market where there is still literature is limited.
Practical implications
OTT providers should determine their objectives for using gamification and design the game mechanics according to the optimal combination of elements – components, controls and courses.
Originality/value
According to the author’s knowledge, this is the first paper to examine consumer attitude toward gamification and OTT provider based on game mechanics. It provides an understanding on the interaction of elements in game mechanics and shows that different element combinations can be used to meet different goals.

Abstract
Purpose
This study aims investigate the effects of electronic human resource management (e-HRM) on communication pace and processing time reduction through the mediation of organizational agility. The study also investigates the moderating role of technological attitude (TA) on the relationship between e-HRM and organizational agility.
Design/methodology/approach
The data was collected from 331 information and communication technology (ICT) companies – one respondent from each company working in the Human Resource Management (HRM) department. The data was analyzed through the partial least square structural equational model (PLS-SEM) using WarpPLS7.0 software to test the study’s hypotheses.
Findings
We found that e-HRM has positive significant effects on communication pace and processing time reduction through the mediation of organizational agility. Furthermore, TA is found to be positively moderating the relationship between e-HRM and organizational agility.
Research limitations/implications
The study adds significant value to the existing knowledge base on e-HRM by providing empirical insights about the role of e-HRM in optimizing the communication pace and processing time of today’s businesses.
Practical implications
The study also provides invaluable insights to practitioners to replace conventional HR systems with e-HRM to better perform HR functions by optimizing communication pace and processing time in the current fast-paced era.
Originality/value
E-HRM has become an issue of great significance in the contemporary corporate landscape to improve operational efficiency. Despite its widespread adoption in the corporate world, empirical evidence on e-HRM, particularly on its consequences, is still inconclusive.
