Cationization of cotton is an effective tool that solves environmental problems by using vat dyes. In this research, the cationizing efficiency of Cibafix WFF and PrefixK are studied to replace toxic conventional redox agents with ecofriendly alternatives. It is found to be a better method when compared with the conventional and existing method of vat dyeing of cotton. Conditions, such as concentration of cationizing agents, time, temperature and pH, are optimized. Such conditions show better color strength when compared with conventional dyeing methods. The effect of cationization on color strength and fastness is observed, and show higher value in both light and dark shades. The cationized samples show comparable quality and are cheaper in cost when compared with the normal vat dyeing method. Cationization of cotton with Cibafix WFF is found to be a successfully and commercially viable process.

While aiming to create methods for fibre recycling, the question of colours in waste textiles is also in focus; whether the colour should be kept or should be removed while recycling textile fibre. More knowledge is needed for colour management in a circular economy approach.

The research included the use of different dye types in a cotton dyeing process, the process for decolourizing and the results. Two reactive dyes, two direct dyes and one vat dye were used in the study. Four chemical treatment sequences were used to evaluate colour removal from the dyed cotton fabrics, namely, HCE-A, HCE-P-A, HCE-Z-P-A and HCE-Y-A.

The objective was to evaluate how different chemical refining sequences remove colour from direct, reactive and vat dyed cotton fabrics, and how they influence the specific cellulose properties. Dyeing methods and the used refining sequences influence the degree of colour removal. The highest achieved final brightness of refined cotton materials were between 71 and 91 per cent ISO brightness, depending on the dyeing method used.

Only cotton fibre and three different colour types were tested.

With cotton waste, it appears to be easier to remove the colour than to retain it, especially if the textile contains polyester residues, which are desired to be removed in the textile refining stage.

Colour management in the CE context is an important new track to study in the context of the increasing amount of textile waste used as a raw material.

A water repellent fluorenated monomer was used in a mixture of monomers for treatment of pine wood samples, using both, impregnation and graft copolymerization methods. This resulted in obtaining a new wood‐based material, the properties of which are superior to those of the natural untreated one. The total polymer loading was generally low, but it was sufficient for improving the mechanical properties with an obvious decrease in the water uptake. Better results of bending strength can be obtained on treatment using the graft copolymerization technique, this can be attributed to the chemical bonding of the polymer with cellulose on grafting.

Rosin‐modified polyesteramide resins are prepared covering a wide range of oil lengths by partial replacement of hydroxy ethyl fatty acid amides employed in resin formulations by rosin‐diethanolamine derivative without affecting the resin constants. This is followed by a study of the optimum amount of modifier which improve the resins performance and durability without affecting the other properties. Optimum modifier concentration and durability characteristics are then determined.

This study aims to investigate the mediating role of management control system (MCS) characteristics in the relationship between state type, reflected through societal institutions (SIs), and two sets of management accounting techniques (MATs), namely, performance measurement techniques (PMTs) and cost measurement techniques (CMTs).

Structural equation modeling was used to analyze data from a cross-sectional survey of 136 firms in the United Arab Emirates (UAE).

The findings show a direct positive impact of state-type construct on MCS characteristics, and that MCS characteristics partially mediate the reported significant relationships between state type and the use of PMTs. While the findings show a similar positive relationship between state type and CMTs, MCS characteristics do not mediate this relationship.

Although these results are affected by limitations associated with the survey method used, they are useful in explaining the necessary conditions supporting the use of MATs in general and performance measurement techniques in particular.

The study uses a cross-section of companies in the UAE, an attractive global investment destination, as its sample. The results can help investors better understand the choice of MATs in the UAE and its relation to MCS characteristics.

This study contributes to management accounting literature by determining the mediating role of MCS characteristics on the relationship between state type and the choice of two sets of MATs, whereas existing literature assumes a direct relation between the two.

Adopting a followership perspective and drawing upon the literature on perceived support, we provide new theoretical insights into when and why supervisors engage in unethical behavior with the intention of benefiting a “favorite” follower, referred to as unethical favoritism behavior (UFB).

We conducted two studies: an experiment and a multi-rater field study. Data were collected and analyzed using AMOS and the Macro process for SPSS.

We found that a follower’s standing among his or her peers in terms of citizenship behaviors toward their supervisor (i.e. relative organizational citizenship behaviors toward supervisor or ROCBS) has a positive effect on the supervisor’s perception of the follower’s support. The results further reveal that the choice of the supervisor on whether to reciprocate or not the perceived support (triggered by ROCBS) with UFB depends on the supervisor’s competence uncertainty (i.e. the degree of supervisor uncertainty regarding his/her work competencies).

Our findings broaden the way the supervisor–follower relationship has traditionally been investigated in the organizational behavior literature by showing that under certain circumstances, followers’ good behaviors might become an antecedent to supervisors’ unethical acts.

Various polyesteramide resins are prepared in which a stoichiometric amount of hydroxy ethyl fatty acid amides (diol) are replaced by the bifunctional nicotinic acid and aisonicotinic acid derivatives of diethanolamine and triethanolamine without affecting the resin constants. The inclusion of nicotinyl and isonicotinyl residues would expect to prevent microbial growth and may also act as corrosion inhibitor.

This article uses a survey of Certified Management Accountants (CMA) in the six Arab Gulf Cooperation Council (GCC) countries to examine the importance that CMAs place on a number of management accounting practices for the efficient operation of their business and to determine the degree of adoption of that management accounting practice by their organization. The findings indicate a large discrepancy between what accountants consider effective management accounting tools and the use of those tools by their companies’ senior management team. Evidence suggests that companies in the GCC rely on the traditional management accounting practices rather than the more recently developed tools. In addition, the management accountants of GCC companies feel that it would be more important for their businesses to emphasis a range of non‐financial tools as well as to adopt a more strategic management focus using tools.

The paper aims to the preparation of novel disperse dye based on azo salicylaldehyde derivatives TF-A [2-hydroxy-5-((3-(trifluoromethyl)phenyl)diazenyl)benzaldehyde] and full evaluation of their use as disperse dye TF-ASC [bis 2-hydroxy-5-((3-(trifluoromethyl)phenyl)diazenyl)benzaldehyde Schiff base with 4,4'-methylenedianiline] for dyeing polyester fabric at various conditions.

The dispersed dye was synthesized via Schiff base condensation in the presence of ceric ammonium nitrate cerium ammonium nitrate 10 mmole% as an eco-friendly catalyst at room temperature. The chemical structure of the prepared dye was characterized via elemental analysis, Fourier-transform infrared spectroscopy, 1H- and 13 C-NMR spectroscopic analysis tools. This study thoroughly examined the dyeing of disperse dye TF-ASC on polyester at various conditions. The characteristics of dyed polyester fabric were measured by colour measurements, as well as light, washing, crock fastness and finally, colour strength. The discrete fourier transform (DFT) theoretical studies, including E_HOMO, E_LUMO and optimized geometrical structure, were assumed and discussed in detail.

The results showed that the synthesized organic dye TF-ASC was highly functional and appropriate for this kind of dyeing method. The dyeing fabrics obtained from disperse dye TF-ASC, properties possess high colour strength as well as good overall fastness properties. These dyes had a high affinity for polyester fabric, with just a tiny change in dye affinity when the pH was changed, even under alkaline circumstances. The dye levelness and shade depth of the colour results were good, and there were a variety of hues from light brownish yellow to deep brownish yellow. The results obtained from DFT computational studies such as E_HOMO, E_LUMO, optimized structure, diploe moment µ and electrophilicity index deduced that prepared organic dye TF-ASC is more applicable as a dispersed dye.

This research is significant because it provides a new dye for dyeing polyethylene terephthalate fibres with exceptional brightness and levelness; the method of preparation is a useful pathway due to its being known as a green chemistry method.

This study aims to explore the pandemic's opportunities for enhancing the environmental practices of the food and beverages green supply chains and its effect on the supply chains' viability by exploring the relationship between fear and uncertainty of COVID-19, food and beverages green supply chain management (F&B-GSCM) and supply chains’ viability based on the two dimensions (robustness and resilience) and examine the moderating effect of innovative technology adoption like big data analysis (BDA) capabilities and blockchain technologies (BCT) on this relationship.

This study adopted partial least squares structural equation modeling (PLS-SEM) on a sample of 362 F&B small and medium enterprises (SMEs)’ managers in the Egyptian market for data analysis and hypothesis testing.

The empirical results show that the fear and uncertainty of the pandemic have a significant positive effect on green supply chain management (GSCM). Also, BDA moderates the relationship between fear and uncertainty of COVID-19 and GSCM. However, BCT do not moderate that relationship. Similarly, GSCM positively affects supply chain viability dimensions (robustness and resilience). In addition, F&B-GSCM significantly mediates the relationship between fear and uncertainty of COVID-19 and supply chain viability dimensions (robustness and resilience).

Food and beverages (F&B) managers could develop a consistent strategy for applying BCT and BDA to provide clear information and focus on their procedures to meet their stakeholders' needs during COVID-19. Governments and managers should develop a consistent strategy to apply food and beverages supply chains (F&B SCs)' green practices to achieve F&B SCs' resilience and robustness, especially during the pandemic.

The Egyptian F&B SCs have been linked directly with many European countries as a main source of many basic food and agriculture products, which have been affected lately by the pandemic. Based on the “social-cognitive,” “stakeholder” and “resource-based view” theories, this study sheds light on the optimistic side of the COVID-19 pandemic, as it also brings the concepts of F&B-GSCM, SC resilience, SC robustness and innovative technologies back into the light, which helps in solving F&B SC issues and helps to achieve their viability.
