The purpose of this study was to investigate the polyacrylic polymer/Al₂O₃ as a new nanocomposite coating to protect brass and Al-bronze in 3.5% NaCl and the role of alumina formulation on their protection efficiency

The corrosion efficiency of the nanocomposite coating (NCC) was evaluated by open circuit potential and electrochemical impedance spectroscopy (EIS).

The protection efficiency was more in the case of Al-bronze even for the same formulation of alumina NCC indicated the Cu substrate contribution. The Cu oxides in alloys and Al₂O₃ from the NCC and Al-bronze were responsible for this protection.

All the techniques supported each other, the presence of alumina was responsible for the corrosion protection efficiency.

Aims to study inhibitive properties of new compounds that are based on the Wurtzite structure of zinc oxide with an admixture of cobalt using zinc oxide as a reference.

The conditions for the preparation of pigments using different ratios of both cobalt and zinc were investigated. Characterization of these pigments was carried out using spectroscopic methods of analysis via X‐ray diffraction, transmission and scanning electron microscopy. Also, evaluations of the pigments prepared, in terms of oil absorption, specific gravity, water‐soluble matter and pH, using international standard testing methods was performed. The pigments prepared were incorporated in anticorrosive paint formulations based on medium oil alkyd resin as a binder. The physico‐mechanical properties of the relevant paint films were obtained, while their anticorrosive properties were assessed by tests in 3.5 percent NaCl solution for 28 days. Electrochemical measurements based on corrosion rates of paint films also were studied.

The results showed that the anticorrosive protection properties of the pigment prepared were better than with zinc oxide pigment alone.

The pigments prepared can be used as reinforcing filler in different rubber and plastic composites providing them with an intense green color. As the concentration of cobalt oxide exceeds 15 percent, the reinforcing and effects decreased and vice versa.

Zinc chromate is one of the anticorrosive pigments most frequently used in the formulation of primers. However, its environmental aggressiveness and toxicity severely restrict its use and different green alternatives have been proposed in order to replace it. One such alternative is the pigment evaluated in this paper. New pigment applications, such as reinforcing fillers for rubber and plastic composites, also could be attractive.

This research aims to provide an empirical assessment of consumer sentiment towards corporate sustainability practices in the context of developing countries, specifically Egypt.

A survey was deployed to measure the importance of corporate sustainability activities to consumers.

The results demonstrate that consumers are concerned with all the measured dimensions of corporate sustainability practices, yet some of the dimensions are more critical to them than others.

By providing an overview of how consumers' purchase behavior is affected by corporate sustainability practices, this research contributes to knowledge on understanding more about sustainable consumer behavior in developing countries, which is scarce. Moreover, this research goes further by segmenting sustainable consumers into groups based on their sustainability concerns.

This research offers clarity regarding process supply chain integration through two deliverables: (1) developing six constructs (both integrative mechanisms and integrative practices for internal, customer, and supplier integration); and (2) empirically testing a theoretically grounded supply chain process model using three distinct datasets (internal, customer, and supplier integration).

The construct development procedure involved a continuous improvement cycle for identifying 1,450 items previously used to measure internal, customer, and/or supplier integration constructs; classifying the items into one of six categories; and refining the instruments based on pilot data and peer feedback. Three surveys (targeted key informants based on their specialized knowledge on internal, customer, or supplier integration) were disseminated for evaluating the measurement instruments and testing the theoretically grounded supply chain management process models, by performing the Covariance-Based Structural Equation Modeling (CB-SEM) analysis technique.

The findings revealed consistencies across all three dimensions of supply chain integration where integrative mechanisms and integrative practices are distinct constructs; integrative mechanisms make it possible for integrative practices and supply chain orientation to occur in a supply chain company; and integrative practices and supply chain orientation improve business performance.

Our study contributes to answering how process-oriented supply chain management occurs, responding to calls for research in the supply chain management discipline and advancing theory development around supply chain integration. The theoretical and managerial contributions of developing six constructs and testing three supply chain management process models relate to identifying the specific aspects of supply chain integration that improves business performance. The three tested models also reveal both direct and mediating effects of integrative practices and supply chain orientation, which contributes to the practical understanding of effective supply chain management implementation.

This study presents a systematic framework for maintenance strategy development of manufacturing process machinery. The framework is developed based on the reliability-centred maintenance (RCM) approach to minimise the high downtime of a production line, thus increasing its reliability and availability. A case study of a production line from the ghee and soap manufacturing industry in Taiz, Yemen, is presented for framework validation purposes. The framework provides a systematic process to identify the critical system(s) and guide further investigation for functional significant items (FSIs) based on quantitative and qualitative analyses before recommending appropriate maintenance strategies and specific tasks.

The proposed framework integrates conventional RCM procedure with the fuzzy computational process to improve FSIs criticality estimation, which is the main part of failure mode effect criticality analysis (FMECA) applications. The framework consists of four main implementation stages: identification of the critical system(s), technical analysis, Fuzzy-FMECA application for FSIs criticality estimation and maintenance strategy selection. Each stage has its objective(s) and related scientific techniques that are applied to systematically guide the framework implementation.

The proposed framework validation is summarised as follows. The first stage results demonstrate that the seaming system (top and bottom systems) caused 50% of the total production line downtime, indicating it is a critical system that requires further analysis. The outcomes of the second stage provide significant technical information on the subject (seaming system), helping team members to identify and understand the structure and functional complexities of the seaming system. This stage also provides a better understanding of how the seaming system functions and how it can fail. In stage 3, the application of FMECA with the fuzzy computation integration process presents a systematic way to analyse the failure mode, effect and cause of items (components of the seaming system). This stage also includes items’ criticality estimation and ranking assessment. Finally, stage four guides team members in recommending the appropriate countermeasures (maintenance strategies and task selection) based on their priority level.

This paper proposes an original maintenance strategies development framework based on the RCM approach for production system equipment. Specifically, it considers a fuzzy computational process based on the Gaussian function in the third stage of the proposed framework. Adopting the fuzzy computational process improves the risk priority number (RPN) estimation, resulting in better criticality ranking determination. Another significant contribution is introducing an extended item criticality ranking assessment process to provide maximum levels of criticality item ranking. Finally, the proposed RCM framework also provides detailed guidance on maintenance strategy selection based on criticality levels, unique functionality and failure characteristics of each FSI.

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.

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.

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.

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).

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

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.

The purpose of this research is to explore the influence of the pandemic on manoeuvring consumption decisions towards goods and encouraging the trial of local food goods in a developing country, Jordan; primarily by taking an internal look into country image from a local perspective. Given the lack of studies analysing the impact of crises on consumption decisions, this research highlights the hidden benefits of the pandemic in shifting the perceptions of local food goods among Jordanian consumers.

This study adopts an exploratory approach to obtain rich, descriptive data to aid in the understanding of the shift in country image perceptions after the COVID-19 crisis and associated influences on purchase intentions. Using a qualitative open-ended approach eliminates the boundaries of closed-end methods of experimental research. Due to the nature of the phenomena being explored in this research, this study adopts the approach of responsive interviews with 26 participants.

Findings indicate that participants’ perceptions of country image and local goods and their consumption changed responding to COVID-19 for different reasons, creating new norms and perceptions of country image and local food goods. The findings precisely indicate a shift from negative to positive perceptions of country image and local food goods due to the pandemic. Results reveal that there are inconspicuous benefits associated with the role of the pandemic in shifting perceptions of country image and local food goods in Jordan.

Consumers’ perceptions and consumption decisions continue reciprocally to respond to and reflect on the COVID-19 crisis. Adjusting to the new normal is now the focus of research to understand the variance in consumption decisions across the world, including in emerging markets such as Jordan. Results also extend research on cue theory, as crisis seems to have a moderating role in the extent of influence cue theory has on perceptions of goods.

Assisting local brands in improving their marketing strategies, by identifying the barriers that hinder the “desire to try” phase among Jordanian consumers.

To the best of the authors’ knowledge, this study is unique and first of its kind, as it investigates perceptions of Jordanian consumers of their country’s image and whether the perceptual change in their country image would also stimulate a shift of perceptions in local food goods concerning the COVID-19 crisis. The results provide new insights into understanding consumer behaviour and preferences in crises; and the inconspicuous benefits that a crisis may have on local goods.

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.

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.

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.

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.

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

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.

This paper aims to determine whether financial performance is affected in firms adopting separately or jointly two sustainability tools (green innovation and environmental, social and governance reporting (ESG)).

The empirical study examines a sample of 211 S&P 500 firms over the 2011 to 2019 period and uses the quantile estimation method.

The results show that two dimensions of ESG disclosure (the social and governance dimensions) and green innovation positively affect financial performance. This result suggests that sustainability tools have a strong financial impact. The positive relationship between green innovation and financial performance is detected at the 10th quantile up to the 70th quantile. This finding suggests that financial performance needs a moderate investment in green innovation. When considering the joint effect of ESG disclosure and green innovation, our findings show that the positive impact of some ESG disclosure dimensions (social and governance) on financial performance is more observable with a moderate investment in green innovation.

This study highlights the prominent role of sustainability tools in financial performance. Despite the contributions of the literature, to our knowledge, the relationship between these tools and financial performance is not yet comprehensively investigated. Sustainability is less studied from the social movement perspective. This paper is among the few to study the effect of ESG reporting on financial performance in a world of green innovation.
