It is globally recognized that food waste has significant economic, social and environmental impacts. This study endeavors to identify the individuals' underlying factors that affect food waste behavior in a social context in Egypt.

Due to the scarcity of research illustrating food waste in a social context, a qualitative research paradigm is employed. In-depth semi-structured interviews are conducted with 18 Egyptian households to report their experiences, thoughts and feelings while eating in a social context.

Based on thematic analysis using grounded theory procedures, eight main elements affecting creation and reduction of food waste in social contexts are identified. Additionally, the authors investigate the role of emotions in social dining contexts. A key finding is that food waste in social events is inevitable and is the acceptable norm in the Egyptian culture. Thus, the first step to reduce food waste is paying more attention to change culture. Persuading people with the negative consequences of food waste issue on behalf of their cultural values will be more challenging and may require more innovative approaches.

Although food waste issue is one of the contemporary issues in the world, very little is known about how social food consumption leads to food waste behavior. This study employs social influence theory and the collectivistic culture orientation to investigate the unanswered question of why food gets wasted in social meal context.

This study examines the effect of five price perception dimensions (price consciousness, price mavenism, sale proneness, price-quality schema, and prestige sensitivity) on consumer's perceived value (acquisition value, and transaction value), and how perceived value affects consumers' behavioral intentions (purchase intentions, and intentions to recommend). It also examines the moderation role of face consciousness.

A quantitative research methodology using online survey technique is employed to collect cross-cultural data from respondents from China (n = 371) and Egypt (n = 384). Structural equation model (SEM) via SmartPLS v.3.2.9 is conducted to analyze data.

The results show that consumers’ behavioral intentions toward suboptimal fresh produce are positively affected by both dimensions of perceived value. As well as, perceived value is influenced by different price perception dimensions. Moreover, face consciousness partially moderates the relationship between perceived value and behavioral intentions.

To best of the authors’ knowledge, it is the first study to associate price perception dimensions with purchase value dimensions in the context of suboptimal products. It also contributes to utility and purchase value theory by employing the distinct measures of both perceived acquisition value and transaction value, to enable us to obtain a better understanding of the whole picture of perceived value. In addition, it contributes to regulatory focus theory through the inclusion of face consciousness in the purchase value model. Moreover, up to the researchers' knowledge, prior investigation on these issues in Egypt and China as a cross-cultural research does not exist.

This study extends the theory of planned behavior (TPB) through the inclusion of motivating variables for suboptimal produce preference (i.e. environmental concern, food waste awareness, and familiarity), and demotivating variables (i.e. health consciousness and risk perception) to investigate behavioral intentions toward suboptimal produce.

A quantitative research methodology using the online survey technique is employed to collect cross-cultural data from respondents from China (n = 430) and Egypt (n = 441). Structural equation modeling (SEM) via SmartPLS v.3.2.9 is used to analyze data.

The proposed extended TPB model could enhance predicting consumers' behavioral intentions toward suboptimal produce except for “environmental concern” since it has been found that environmental concern has a nonsignificant effect on consumers' attitudes and behavioral intentions toward suboptimal produce in both countries. The results also reveal that the proposed extended TPB constructs could predict 79.9% of intentions to purchase suboptimal produce and 65.3% of the variance in intentions to recommend such produce for others.

This study is one of the few attempts that investigates the suboptimal food consumption based on a theoretical lens by extending the TPB model. Previous studies on suboptimal food do not pay attention to the demotivating variables such as health consciousness and risk perception, and thus, this thesis represents the first effort that sheds light on such variables. Moreover, prior investigation on such issues in Egypt and China as a cross-cultural research has not existed.

The present research extends the existing literature of halal tourism and Muslims’ travel decision-making by applying information-seeking models and the planned behavior theory to identify the process of decision-making to travel to non-Islamic destinations. This study aims to identify the views of Muslim travelers who traveled before to non-Islamic destinations to evaluate their information search experience and how their travel decision is formed.

Semi-structured interviews are conducted with a sample of Muslim travelers who visited a non-Islamic destination during the past five years. Data saturation resulted in 17 interviewees from different Islamic destinations, namely, Egypt, Morocco, Sudan and Pakistan.

Muslim interviewees indicate the relative importance of reference groups compared to the government websites as a source of information. This study concludes some remarkable results regarding the importance of some halal marketing strategies such as halal searchability and availability, halal certification and appraisal, halal at airports and halal hotels. It presents an emergent framework that shows the factors affecting visiting a non-Islamic destination regarding halal issues for Muslim travelers.

It provides destinations’ official tourism managers with various strategies to brand their destinations as Muslim-friendly destinations.

Investigating the process of decision-making of traveling to non-Islamic destinations from Muslim travelers’ perspective is limited. Examining the role of information-seeking behavior in Muslim travelers’ decision-making is scarce.

The purpose of this paper is to describe a framework for enhancing organizational productivity and capacity building at the national, industry-wide level that is based on an active collaboration between elements of the industry that the authors will refer to as the organization and the educational system that trains/educates the human resources that play a vital role in enabling the organization to acquire and then maintain the competitive advantage needed to be successful.

This framework is based on the concept of competencies of the human resource and a competence-based model for recruiting and developing these human resources. This framework has been successfully applied by the Kemt Enterprise Training Partnership (ETP)/Technical and Vocational Education and Training (TVET-Egypt) project in the Egyptian papermaking industry to solidify an understanding of the required competencies in this sector. For the purposes, the term competency will be defined as a set of skills, knowledge and behavior that allows employees to do their jobs effectively and efficiently without interfering with either other tasks or tasks they will encounter in the future.

Organizational productivity will be assumed to be related to having a workforce that is both competent and of the appropriate size, and can be determined using an organizational function map coupled to the development of a set of related occupational standards.

The paper proposed a national framework competence-based model which collaborates all the national efforts to enhance the national competitiveness.

Water is a vital natural resource without which life on earth would be impossible. Properties of synthetic dyes like high stability and noxious nature make it difficult to remove them from the effluent. This review focuses on the removal of synthetic dyes using nanoparticles (NPs) based on the adsorption principle.

Adsorption technique is widely used to remove synthetic dyes from their aqueous solution for decades. Synthetic dye removal using NPs is promising, less energy-intensive and has become popular in recent years. NPs are in high demand for treating wastewater using the adsorption principle due to their tiny size and vast surface area. To maximise environmental sustainability, the utilisation of green-produced NPs as efficient catalysts for dye removal has sparked attention amongst scientists.

This review has prioritised research and development of optimal dye removal systems that can be used to efficiently remove a large quantity of dye in a short period while safeguarding the environment and producing fewer harmful by-products. The removal efficiency of synthetic dye using different NPs in wastewater treatment varies mostly between 75% to almost 100%. This review will aid in the scaling up of the wastewater treatment process.

There is a lack of research emphasis on the safe disposal of NPs once the reuse efficiency significantly drops. The relevance of cost analysis is equally critical, yet only a few papers discuss cost-related information.

Comprehensive and planned research in this area can aid in the development of long-term wastewater treatment technology to meet the growing need for safe and reliable water emphasising reuse and desorption efficiency of the NPs.

Environmental issues and lack of drinking water have forced researchers to find some alternatives to wastewater treatment. Because dyes are used in a variety of industrial applications such as textile and pharmaceutical, wastewater of these factories leads to several environmental problems. Using catalysis under ultraviolet-irradiation (photocatalysis) is one of the cases that is used in wastewater treatment. The purpose of this work is the photocatalytic degradation of dye (Reactive Red 198) and pharmaceutical (tetracycline) using MIL-53(Fe) and MIL-100(Fe).

In this work, Reactive Red 198 (RR198), an anionic dye and tetracycline as a pharmaceutical are tested with two catalysts, MIL-53(Fe) and MIL-100(Fe). Catalyst synthesis method and characterization were discussed by X-ray diffraction, scanning electron microscopy and Fourier Transform Infrared analyses, and their results are described in detail.

Dye concentration varies among 15, 20, 30 and 40 mg/L for MIL-100(Fe) for which the removal percent is 97%, 94%, 89% and 58% and for MIL-53(Fe), dye concentration increases from 20 to 40, 60 and 80 mg/L, the removal percent of which is 98%, 88%, 75% and 50%. Pharmaceutical degradation by MIL-53(Fe) and MIL-100(Fe) was 75% and 80%, respectively.

Photocatalytic degradation of RR198 and tetracycline using MIL-53(Fe) and MIL-100(Fe) was not studied in detail.

This study investigates the nature of the association between profit warnings and stock price informativeness in the context of Jordan as an emerging country.

The authors used a large panel data set that related to stock price synchronicity and profit warnings percentages on the Amman Stock Exchange for the period spanning 2007–2018. Robust regression was used as a parametric test. This enabled us to obtain stronger results that fall in line with our prediction that a profit warning encourages firm investors to collect and process more firm-specific information than common market information.

Our findings show a significant positive effect of profit warnings on the amount of firm-specific information incorporated into stock price, which means that the greater the percentage of profit warnings the more likely that more firm-specific information will be incorporated in stock price synchronicity. In addition, corporate governance characteristics (moderating variables) significantly increase the level of the relationship between profit warnings and stock price synchronicity.

Our study results could be useful to investors, senior managers, and regulators in Jordanian firms, particularly in relation to decisions about enhancing the quality of financial statements. In addition, our results provide new evidence about the consequences of earnings announcements for information content and the informativeness of stock prices. Our methodology and evaluation of profit warnings may also demonstrate useful evidence for future researchers on profit warnings and stock price informativeness in developing economies, especially given that such evidence is scarce in developing economies.

This research is the first study of its kind on emerging markets, particularly in the Middle East. Moreover, entering the corporate governance variables as moderating variables to the robust regression was found to be more powerful than other regressions.

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.

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.

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.

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.

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.

This study aims at evaluating the technical efficiency (TE) of healthcare systems in the Arab region and exploring the key factors that affect the efficiency performance.

The study applies a two-stage Data Envelopment Analysis (DEA) approach to a sample of 20 Arab countries. In the first stage, a DEA model is used to calculate the TE scores of the examined healthcare systems in 2019 and 2010, following both the output and input orientations of efficiency. In the second stage, a censored Tobit model is estimated to investigate the determinants of healthcare efficiency.

DEA results of 2019 indicate that achievable efficiency gains of the Arab countries range from 0.4% to 16% under the output and input orientations, respectively. Six countries are efficient under both orientations. Although the average efficiency scores of the Arab countries have deteriorated between 2010 and 2019, Djibouti and Sudan had the greatest efficiency improvements between the two years. Bahrain, Mauritania, Morocco and Qatar proved to be efficient in 2010 and 2019 under the two orientations of efficiency and according to the two DEA specifications followed. The Tobit model reveals that corruption and government health expenditure tend to have an adverse impact on healthcare efficiency.

The author evaluates healthcare efficiency and healthcare's efficiency determinants in the Arab countries. Regardless Arab countries' diversity, these countries are facing common health challenges, including diminishing role of governments in healthcare financing; increased out-of-pocket healthcare spending; poor healthcare outputs and prevalence of health inequities resulting from weak governance institutions. Comparing the efficiency of healthcare systems between 2010 and 2019 gives insights on the potential impact of the Arab spring uprisings on healthcare efficiency. Moreover, examining the determinants of healthcare efficiency allows for better understanding of how to improve the efficiency of healthcare systems in the region.
