Abstract

Purpose

Fingerprints and blood samples are important for the identification of individuals and criminals. The present study aims to identify the predominant fingerprint patterns and the association between the fingerprint patterns and ABO–Rh blood groups in Omani population.

Design/methodology/approach

A cross-sectional study was conducted on 200 Omani individuals aged 18 years (104 males and 96 females). The imprints of all right and left-hand fingers were taken, and the types of the fingerprints were determined using a standard protocol. The blood group of all the subjects was recorded. Chi-square test was performed to identify the association between the fingerprint patterns and the ABO and Rh blood groups.

Findings

The loop fingerprint pattern was the most common in Omani subjects (49.4%), followed by whorl (44.9%) and arch (5.7%) pattern. A significant association (p < 0.001) was found between gender and fingerprint pattern. The loop was the highest occurring pattern in the females (54.6%), while the whorl was more in males (50.0%). The whorl pattern was the most common in the AB+ and O− groups. The loop was a predominant pattern in the A+, A−, B+, B− and O+ groups. The Chi-square test also revealed a significant correlation between different fingerprint patterns and blood groups of the subjects (p < 0.001).

Originality/value

The present study is an outcome of undergraduate student's research project thesis for the Doctor of Medicine (MD) program. The results of the present study may help in creating a data bank for biometrics, which can be useful for diagnosing associated diseases and also help in identification of individuals.

Abstract

Purpose

This paper aims to examine the effect of religiosity on the degree of auditor independence given the significance of symbolic gestures constructed by client economic conditions in different situations before and after considering the degree of auditors’ moral development.

Design/methodology/approach

The paper uses an experimental design based on running mixed factorial analysis of variance (SPANOVA) using mainly repeated measures GLM to test the interaction effects between (and within) variables on auditor independence.

Findings

The main findings indicate that there is a significant interactional effect between the degree of moral development and intrinsic religiosity on the degree of auditor independence, given the stimulating effect of the client’s economic gestures/conditions.

Practical implications

The Egyptian economy is growing and ensuring that auditor independence is paramount to sustaining the local, as well as foreign investors’ interest. Hence, this study is very important in highlighting factors that might lead to some impairment of auditors’ independence.

Originality/value

To the best of the authors’ knowledge, this study is the first to test the interactional effect between the religious orientation rather than religious affiliation and moral development on the degree of auditor independence, such a relationship has not been tested before in the literature. Additionally and most importantly, it uses statistical measurement through its experimental design, as there is a lack of studies in terms of auditor independence in Egypt. The existing literature follows the perceptional assessment rather than the real measurement of the degree of auditor independence.

Abstract

Purpose

The purpose of this paper is to investigate the impact of board structure on voluntary corporate disclosure via social media among the top 150 companies listed on the London Stock Exchange.

Design/methodology/approach

A disclosure index comprising of a set of items that encompass two facets of disclosure, namely corporate disclosure via social networks and social media sites, is developed and used. Binary logistic regression is used to test the research hypotheses.

Findings

The results of this study reveal the underlying relations between board composition and control variables as the determining factors of corporate disclosure, i.e. board size, board activism, board independence and board diversity (gender and ethnicity). The gender of the board can affect the corporate disclosure via a social network. The results of this study indicate that an increase in the number of female in the board members leads to higher corporate disclosure using social network. Moreover, firm size has a positive effect on corporate disclosure indicating that large firms tend to disclose more information on their websites and social networks.

Practical implications

The paper provides new insights into the role played by the non-executive female directors in monitoring and controlling managerial processes related to corporate disclosure using social media.

Originality/value

To the best of the authors’ knowledge, this is the first paper that examines the role of board structure in monitoring and controlling management decisions and managerial processes in the area of corporate disclosure via social media.

Abstract

Purpose

The purpose of this paper is to examine customer attitudes toward purchasing counterfeit luxury products (ATPCLP) in two cities in two different countries (Saudi Arabia and Malaysia) by testing the relationships between the various reasons for purchasing those products: social status insecurity, status consumption and value consciousness.

Design/methodology/approach

Questionnaires were distributed conveniently to urban customers in Kuala Lumpur, Malaysia and Jeddah, Saudi Arabia. Altogether 658 useable questionnaires were collected and analyzed using descriptive statistics, general linear model of univariate analysis of variance and structural equation modeling.

Findings

Quality, price, popularity and status signaling represent the main motivating factors for their brand choices of counterfeit luxury products among the two country groups of customers. As expected, customers' social status insecurity influences their ATPCLP, but not their status consumption. However, status consumption does positively moderates the relationship of their social status insecurity and their ATPCLP. Furthermore, customers' value consciousness influences their ATPCLP and moderates the relationship between status consumption and ATPCLP. The impact of status consumption on ATPCLP depends on the importance one places on the value of the products. However, the authors found no differences in social status insecurity, status consumption and value consciousness, on their ATPCLP among the customers. Some implications and limitations of the results are discussed.

Research limitations/implications

The use of convenience sampling and mainly college students (in Saudi Arabia) as respondents represent the main limitations of this study.

Practical implications

The practical implication of this study is to discourage the purchasing of counterfeit luxury products in their respective country Malaysian marketers need to stress that their genuine products are of top quality while Saudi marketers need to stress that their genuine products are of well-known brands that are sourced from well-known countries of origin. Besides, Malaysian marketers need to offer genuine products that are not overly priced or ones that indicate value-for-money while Saudi marketers need to convey the message that their genuine products could help enhance or uplift their customers' social status. In this study, the authors did not find any support for differences in ATPCLP between the two rather different Muslim-majority countries. This could be due to the fact that the majority of the respondents were females in their mid-20s and that both countries have a growing number of young customer base, which makes them particularly attractive target customers for branded/luxury products and, at the same time, easy preys to luxury products counterfeiters. This implies that there are still more opportunities for academics to study the topic or related topics in the future.

Originality/value

As far as the authors know, no one has undertaken a comparative study involving two very different Islamic majority countries (more conservative mono-cultural and mono-ethnicity Saudi Arabia versus less conservative multicultural and multi-ethnicity Malaysia) before.

This study aims to investigate the determinants of United Arab Emirates (UAE) and Qatar consumers’ perceptions of organic food.

Abstract

Purpose

This study aims to investigate the determinants of United Arab Emirates (UAE) and Qatar consumers’ perceptions of organic food.

Design/methodology/approach

Using a survey approach and focusing on six known determinants identified from empirical studies, data were analysed using a mean difference analysis and a multi-regression model.

Findings

Citizens in both countries had similar access to organic food products, yet consumer perceptions differed significantly. Given the geographical, cultural and topographical proximity and similarities of these countries, differences in the mean values indicate that targeted or bespoke marketing is required to attract customers.

Research limitations/implications

One limitation of this study its sample size that may limit the generalizability of its results. However, the highly statistically significant results offset this to some extent as the differences the authors have demonstrated are likely to be real. These do require confirmation by further similar studies. The study relied on a random sample of respondents who might have exhibited bias in answering questions.

Practical implications

The two countries central to this research study, the UAE and Qatar, have vested interests in supporting the organic food product market that mainly concern supporting and promoting the health of their citizens and the environment. As shown in this paper, the key obstacles preventing consumers’ accessing organic products are availability and price. With appropriate governmental subsidies and logistics support, however, these barriers can be overcome.

Social implications

If governments are sincere in their declarations that the health and welfare of their citizens is of prime importance, they will support attempts to promote the sale and consumption of organically grown food. The results of this study can help to inform such policies.

Originality/value

This study provides insights into the most important factors that influence consumers’ attitudes towards organic foods. This study fills a gap in the existing research on consumer buying behaviour for organic food in two Middle Eastern countries.

Abstract

Purpose

This study aims to evaluate and investigate the existing process of establishing a banking relationship with politically exposed persons.

Design/methodology/approach

This study used qualitative techniques of semi-structured interviews with senior compliance officers of financial institutes in Pakistan.

Findings

This study found that the existing mechanism of identification and verification of politically exposed persons (PEPs) is ineffective. Financial institutes face challenges like the quality of name screening data sets, cost of identification and verification, role and control of the regulator, the influence of politically exposed persons, the opaqueness of laws and international connections of the politically exposed persons. Further, financial Institutes are burdened by regulators to perform robust PEP customer due diligence but do not guide and provide the right tools.

Originality/value

This paper aims to find challenges faced by financial institutes before onboarding the PEPs. Further, very limited studies on this topic have been conducted in Pakistani context.

Abstract

The impetus for the development of audit committees in 1970's was the unexpected corporate failures that resulted from corporate misconduct. The situation seems to have hardly changed almost 30 years on. As corporate failures become more spectacular due to big‐names failures and the ever‐developing means of communications that brought such failures to the forefront of the news and almost into every household, more attention is drawn nowadays to the role of audit committees in preventing such failures. With audit committees now the norm in developed countries and increasing number of emerging economies, the role of audit committees has developed from being seen as means of strengthening the external financial reporting process to being seen as means of detecting and preventing corporate misconduct and failures. Thus this study investigates the international developments of audit committees and their role in the issues concerned. It also evaluates the advantages and disadvantages of audit committees, as well as providing possible suggestion to the crucial role that audit committees could play in preventing and detecting corporate misconduct and failures.

Abstract

The rapid spread and acceptance of globalization and the enormous developments in information technology, has led to dramatic changes in the business environment. These changes have brought new challenges not only to business but also to business education. Business schools that prepare future managers in different disciplines are responsible for closing the gap between the skills acquired by its graduates and the required skills by the global markets. This paper identifies the challenges facing accounting education in providing students with the knowledge and skills that raise their competency level to meet that required by the market. These challenges warrant that the competency level of accountants should be improved. Current accounting education and the skill levels of accountants are not in line with what is required in the dynamic environments of global business. A strategic plan for closing the gap between the acquired and required skills is presented to help prepare students for facing and dealing with the challenges of the new global business environment.
