The purpose of this study comes from the need of defining improved durability values and the realization of a good traceability management for selected vegan cheeses has suggested the comparison between a processed cheese and its analogous version without animal-origin raw materials. The durability should be studied at a well-defined temperature, probably agreed among the food producer and the food processor. In addition, the traceability system should consider many components and related suppliers.

A supply chain risk assessment analysis has been carried out with relation to two different products: an analogue cheese and a vegan cheese-like preparation. Raw materials and ingredients have been evaluated (production method and origin; geographical identification), with the aim of identifying simplified food.

An assessment of food supply networks has been carried out. In the first situation (analogue cheeses), the ingredient “cheeses” shows an important complexity: five suppliers with a related six-interconnection hub. On the other side, vegan cheeses are obtained from 11 ingredients (a challenging hub); four of them may be produced from 2–5 components of different origin (five total hubs). Tested processed cheeses are represented by means of a linear food supply network with two hubs (cheeses and “arrival” show degrees 6 and 9, respectively). Networks concerning vegan cheeses include five different hubs: four complex raw materials (degree: 2, 3, 4 and 5) and the “arrival” step (degree: 12).

The information load of vegan cheeses (two hubs, degrees >> average degree) appears high if compared with processed cheeses (two hubs), although the complexity of networks appears similar. Vegan cheeses may seem technologically simpler than processed cheeses and be sometimes questioned because of important traceability issues. Adequate traceability countermeasures in terms of preventive monitoring actions should be recommended when speaking of vegan cheeses. Anyway, a centralized manager would be always required.

This paper aims to provide a comprehensive overview of existing research on stigma in Arab countries.

A rapid review approach was used, leveraging the Scopus database to identify relevant articles. This streamlined method allows for timely assessments of the current state of knowledge, identifies research gaps and is particularly relevant given the social and cultural dynamics in Arab countries.

This study identified a growing interest in stigma-related topics in Arab countries, with a notable increase in the number of publications and citations over the past decade. Research focused on various aspects of stigma, including mental health, HIV, COVID-19 and diverse health conditions, shedding light on the prevalent challenges faced by different populations. Additionally, comparative studies highlighted the influence of culture and gender on the expression of stigma in the region.

To combat stigma in Arab countries, this study suggests the need for culturally sensitive interventions, integration of mental health services into health-care systems and the development of public health campaigns. These measures should be designed to protect vulnerable populations and prioritize educational initiatives for both the younger generation and health-care professionals.

Reducing stigma in Arab countries is crucial for fostering greater social cohesion, equality and overall well-being. The study underscores the importance of collaborations to adapt successful strategies to the unique Arab context.

This paper fills a crucial research gap by investigating stigma in Arab countries, emphasizing the need for culturally sensitive interventions, education integration and international collaboration to combat it effectively.

Significance of Knowledge The functional name of the Holy Quran is ‘huda’, the guiding light. It focuses divine light on each and every object separating thereby the right from the wrong' (al‐furqan). As this is accomplished by dint of knowledge (al‐ 'ilm). All these three guiding elements namely huda, furqan and ilm, are lined‐up by Allah, the Lord Providence (Rabb‐ulalamin), for earthly welfare (hasanah) and other‐worldly salvation (falah) of human beings. In Quranic context, knowledge, therefore, carries a great significance.

In light of the inequality in access to farming land and the high prevalence of child malnutrition in Sudan, there is a lack of empirical research on the relationship between land ownership and child nutritional status. This study aims to examine the influence of agricultural landholding on the nutritional status of children under the age of five in rural Sudan.

The study utilizes data from Sudan’s 2014 Multiple Indicator Cluster Survey (MICS), covering a sample of 10,753 rural children. The empirical analysis uses the two-stage least squares (2SLS) approach, adopting various estimation methods and model specifications for robustness check and comparison.

The results demonstrate that agricultural land has a positive and significant effect on reducing child malnutrition, signifying that children from families with agricultural land are less susceptible to malnutrition in Sudan. When examining the male and female sub-samples separately, the findings indicate a positive influence of land ownership on child malnutrition in the female sub-sample, while no significant impact is observed in the male sub-sample. This indicates a gender disparity in the effects of land ownership on child nutrition, with girls benefiting more from access to agricultural land compared to boys.

The study has several significant contributions. First, this is the sole study that examines the impact of agricultural land ownership on child malnutrition in Sudan. Second, considering the gender variations in nutritional status, investigating the influence of land ownership on child nutrition across genders addresses a significant gap in the current literature. Finally, the findings resulting from this study can contribute to achieving the United Nations Sustainable Development Goals (SDGs) to be achieved by 2030, precisely focusing on SDG2 Goal 2: Zero hunger and SDG 10: Goal 10: Reduced inequalities.

This study aims to examine the effect of audit client’s use of blockchain (BC) on auditing accounting estimates (AEs), especially the inherent risk (IR), control risk (CR) and collection of audit evidence.

The study used a questionnaire to collect data for a sample of 249 auditors. A partial least squares method is used to test the hypotheses.

The results showed positive relationship between audit client’s use of BC and both IR and CR when auditing AEs. The results also showed the BC improves the collection of sufficient and appropriate audit evidence when auditing AEs.

This study did not address all the risks associated with auditing AEs, including fraud, detection, sampling and nonsampling risks, and the procedures and tests for auditing AEs.

There are several implications of this research, including that it informs the revision of auditing standards and guidelines to correspond with successive technological changes, which subsequently clarify the roles and responsibilities of auditors, and the study findings will also cause changes to the design and form of audit procedures so as to obtain sufficient and appropriate audit evidence.

To the best of the authors’ knowledge, this study is considered the first of its kind that deals with the effects of audit client’s use of BC on audit AEs in the Middle East and North Africa region. This study also presented different sets of measures as proxies for measuring IR, CR and AE.

This study aims to investigate the factors, which may potentially influence green product buying decision among young consumers in Malaysia.

A perceived lack of intention to buy green products observed among the Malaysian Generation Young consumers has sparked the interest to carry out this study. With the aid of structured questionnaires, data were collected from a total of 217 respondents, between 18 and 25 years of age.

The results of data analysis indicated that environmental consciousness, eco-label, price and advertising were significant predictors of green product buying behaviour. Contrary to the hypothesis, attitude was not a significant predictor of green buying behaviour among young consumers. The implications of these findings and directions for future research are outlined at the end of this paper.

This study offers empirical insights from the perspective of an emerging economy on the determinants of green products buying behaviour among young consumers.

The purpose of this paper is to investigate the impact of customer-focus on small medium enterprise (SME) performance from the perspective of a resource-based view (RBV).

This research study implemented a survey strategy to gather data from 255 respondents on the registered list of Ghana Enterprise Agency (GEA) in the eastern region of Ghana. Scales used to gather data were operationalized from previous research studies. A structural equation modeling (SEM) path analysis was used to estimate the impact of customer-focus on the performance of SMEs.

The outcomes of this study indicate that customer-focus has a significant positive impact on SME performance, hence backing the current demand for investigating the distinct influence of customer-focus on SME performance. The results show that customer-focus has a positive and significant relationship with financial performance, customer performance, internal business process performance and learning and growth performance, thus supporting the literature on the positive impact of customer-focus on SME performance. Therefore, customer-focus determinants used in this study, including co-creation, networking ties, customer insight and artificial intelligence marketing (AIM), are critical to the optimization of SME performance.

Notwithstanding the importance of this research study mentioned earlier, the study has limitations. Notably, the sample size of this study can be increased to capture SME respondents in other geographical zones that were not included in this study. Future research studies may address how business environment conditions moderate the relationship between customer focus and performance, and also the cause-effect of the relationship between customer focus and business environment conditions on SME performance.

The practical implications consist of two main items. First, this study empowers SME owners and managers to develop a customer focus technique as a central strategic goal in their quest for SME performance optimization. Second, SME owners and managers should progressively exploit the four determinants of customer focus which include co-creation, networking ties, customer insight and (AIM in order to accrue important resources for effective utilization of their customer focus competences as a way to enhance their performance.

This study is targeted at the sound development of SMEs to bring about poverty alleviation and employment. Poverty, unemployment and poor living standards are recognized as vital social challenges in most emerging economies. The establishment of customer focus as an important strategic capability provides opportunities for SME survival, profitability and growth.

Generally, the findings of this research study provide a strong backing to RBV perspective and the proposition that customer-focus and its determinants (i.e. co-creation, networking ties, customer insight and AIM) should be acknowledged as a vital strategic resource for optimizing the performance of SMEs. This research study also provides new knowledge contribution to the present body of knowledge on customer-focus orientation and management literature, particularly in the context of an emerging economy.

Ijara is one of the exchange contracts that is based on selling benefits and services. There are several forms of Ijara: Ijara specified objects, specified work and hiring a private or joint employee. The target of all these is obtaining a benefit. For instance, in the specified Ijara, the lessee desires to obtain a benefit from a specified person in particular, and in the forward Ijara, the purpose is obtaining the benefit in accordance with specified specifications. Indeed, Islamic banks can obtain these benefits through Ijara them from their providers and re-Ijara them to customers upon request. Hence, the purpose of this paper is to determine the Shariah ruling of the Islamic law of Ijara persons' benefits. Moreover, it aims to determine to what extent is it possible to consider Ijara and selling the benefits prescribed in disclosure and as a financing instrument in Islamic banks aiming at providing citizens with services, mainly in the virtual era.

The current research is framed within the descriptive and analytical research through illustrating the nature of Ijara, its conditions, pillars, evidence of its legitimacy and its kinds as well. The methodology used attributes the Quranic verses to their contexts in the Holy Quran and authenticates the noble hadiths of the Prophet.

The current research concludes that it is legally permissible to lease these benefits and re-lease them. However, in the specified Ijara, the hired person must perform the work himself and it is not permissible to be replaced by a third party, whereas in the forward Ijara, the contracted work is permitted to be carried out by a third party as long as it complies with the specifications required and contracted.

This study contributes to the current literature by providing a guide to Islamic banking regulators to promote Ijara in Islamic banking.

Fuel cells technologies are the most promising green energy technologies for diverse applications. One of the fastest growing areas is the portable electronic applications where the power range is the order of 1–100 W. For most of the portable electronic devices, rechargeable battery is the major energy source. Due to limitations like limited capacity, requirement of external power for recharge have led many researchers to look for alternative power sources to power portable electronic devices. The high energy density of fuel cells makes them very attractive alternative to batteries for portable power applications. There are a variety of fuel cell technologies being considered to replace batteries in portable electronic equipment. Direct Liquid Fuel Cells (DLFCs) have attracted much attention due to their potential applications as a power source for portable electronic devices. The advantages of DLFCs over hydrogen fed PEM fuel cells include a higher theoretical energy density and efficiency, a more convenient handling of the streams, and enhanced safety. Unlike batteries, fuel cells need not be recharged, merely refueled. This paper provides an overview on challenges of DLFCs (Direct Liquid Fuel Cells), like fuel crossover, cost, durability, water management, weight and size along with approaches being investigated to solve these challenges. Portable Fuel Cell Commercialization Targets for future and producers of portable fuel cells across the globe are also discussed in this paper.
