PROMETHEE Group Decision Support System and the House of Quality

Quality function deployment (QFD) is a multi-step method that monitors customer needs throughout a product development process. The House of Quality (HOQ) exercise undertaken in the first phase of QFD is considered as the most important, since customer needs must be accurately translated into a set of technical requirements for the final product. This paper provides a PROMETHEE group decision support system (GDSS) approach that integrates the design preferences of the QFD team. We highlight the selection and ranking of the technical requirements in the HOQ exercise, where a group of multidisciplinary decision makers (DMs) in a globally dispersed QFD team is required to input their individual preferences. Our approach advances the HOQ group decision making context in three important areas. First, it treats each criterion and DM as unique in terms of the preference function and threshold levels. Second, it seeks a multi-criteria approach for the HOQ process, where some DMs may play a more important role than others on a certain criterion. Third, sensitivity analysis through the Geometrical Analysis for Interactive Assistance (GAIA) plane provides valuable information about the conflicts, similarities, or independencies between the criterion and the DMs, respectively. A case on an automotive part illustrates the performance of the PROMOTHEE approach with GAIA.     

Examining Organic Food Purchases and Preferences Within Jordan

Continuing economic development in Jordan provides potential food marketing opportunities as a new group of prospective value-added food product consumers emerges. The growing demand for high-value foods such as organically produced items also provides a new potential value-added market for Jordanian farmers. No studies to our knowledge have examined consumer preferences toward organic food items within Jordan. This study provides an initial attempt to fill this knowledge gap by examining the market for organic food items from a demand perspective in order to increase the knowledge available to Jordanian farmers, food processors, and retailers.     

Exchange Rate Regime and Demand for Reserves: Evidence from Kenya,Mexico and Philippines

This paper empirically investigates the demand for international reserves (and foreign exchange reserves) during fixed and floating exchange rates periods in three developing countries: Kenya, Mexico and Philippines. Based on theoretical models, three factors are identified as important for the demand of international reserves and foreign reserves: average propensity to import, volume of imports and variability of reserves. The paper employs the cointegration methodology and error correction method to investigate the relationships. Cointegration tests results indicate a reliable long-run stationary relationship between the international reserves (and foreign exchange reserves) and the stated explanatory variables across countries and sub-periods of fixed and clean float. The error correction results indicate causality from the explanatory variables to the reserves during both the short and long run. This is true during both the fixed and the floating periods.

International Marketing Ethics from an Islamic Perspective: A Value-Maximization Approach

International marketing practices, embedded in a strong ethical doctrine, can play a vital role in raising the standards of business conduct worldwide, while in no way compromising the quality of services or products offered to customers, or surrendering the profit margins of businesses. Adherence to such ethical practices can help to elevate the standards of behavior and thus of living, of traders and consumers alike. Against this background, this paper endeavors to identify the salient features of the Islamic framework of International Marketing Ethics. In particular, it highlights the capabilities and strengths of this framework in creating and sustaining a strong ethical international marketing culture. At the heart of Islamic marketing is the principle of value-maximization based on equity and justice (constituting just dealing and fair play) for the wider welfare of the society. Selected key international marketing issues are examined from an Islamic perspective which, it is argued, if adhered to, can help to create a value-loaded global ethical marketing framework for MNCs in general, and establish harmony and meaningful cooperation between international marketers and Muslim target markets in particular.     

A hybrid clustering and classification approach for predicting crash injury severity on rural roads

As a threat for transportation system, traffic crashes have a wide range of social consequences for governments. Traffic crashes are increasing in developing countries and Iran as a developing country is not immune from this risk. There are several researches in the literature to predict traffic crash severity based on artificial neural networks (ANNs), support vector machines and decision trees. This paper attempts to investigate the crash injury severity of rural roads by using a hybrid clustering and classification approach to compare the performance of classification algorithms before and after applying the clustering. In this paper, a novel rule-based genetic algorithm (GA) is proposed to predict crash injury severity, which is evaluated by performance criteria in comparison with classification algorithms like ANN. The results obtained from analysis of 13,673 crashes (5600 property damage, 778 fatal crashes, 4690 slight injuries and 2605 severe injuries) on rural roads in Tehran Province of Iran during 2011–2013 revealed that the proposed GA method outperforms other classification algorithms based on classification metrics like precision (86%), recall (88%) and accuracy (87%). Moreover, the proposed GA method has the highest level of interpretation, is easy to understand and provides feedback to analysts.     

Conceptualization of the real economy and Islamic finance: Transformation beyond the asset‐link rhetoric

A key factor behind the chronic crises in modern economies is the growing dominance of financialization and the resulting disconnect between the real economy and the financial sector, to which conventional financial industry is a key contributor. In contrast, Islamic finance claims to be real‐economy‐oriented, as all transactions must be asset‐linked (asset‐backed or asset‐based). However, is Islamic Finance based on proper conceptualization of the real economy? What is the real economy and its dynamics? How Islamic finance is interfaced with the real economy? In this article, the claimed real‐economy‐orientation is examined by presenting a conceptualization of the real economy and then evaluating the related discourse accordingly. The analysis presented, especially for noneconomists, exposes a serious gap between the claims about Islamic finance and the real economy it is supposed to advance. Appropriate conceptualization of the real economy can help the industry to be relevant and effective for broader socioeconomic transformation.     

Oil booms and inequality in Iran

We study the response of income inequality to positive per capita oil and gas revenue shocks in Iran. Using historical data from 1973 to 2016 and vector autoregression (VAR) as well as vector error correction (VECM) model‐based impulse‐response functions, we find a positive and statistically significant response of income inequality to oil booms. We also explore possible channels through which oil booms may increase inequality, including private sector credit growth, construction investment, international trade (imports) and real economic output. We find that following an oil boom, higher imports, private sector credit growth, and real economic output can explain the increased income gap to a certain degree in Iran's oil‐based economy. Our analysis can help policymakers evaluate and accommodate the possible positive or negative effects of inequality in Iran resulting from the 2016 lifting of the embargo against the country.     

Why is trait scepticism not consistently reflected in state scepticism? An exploratory study into the role of aesthetic engagement

Where an auditor's sceptical disposition (trait scepticism) is directed toward non-diagnostic information, there is a risk that a sceptical consideration of diagnostic information could be diluted. This may be one reason why trait scepticism is not consistently reflected in sceptical judgments and actions (state scepticism). We develop a scale to measure an individual's predisposition toward engaging with visual elements of the environment (aesthetic engagement) and test, in two experiments employing students and practicing auditors, whether aesthetic engagement moderates the trait – state scepticism relationship. We find that aesthetic engagement attenuates the positive relationship between trait and state scepticism.     

Law‐abiding organizational climates in developing countries: The role of institutional factors and socially responsible organizational practices

The institutional environment of developing countries may lead firms to engage in unlawful firm conduct, which is a pervasive problem in this context. Our paper examines the effectiveness of organizational practices for ensuring that firms adhere to the law in the light of pressures from the institutional environment to be unlawful. Using the lens of anomie theory, we investigate: (a) the negative effect of aspects of the institutional context—regulatory burden and lack of industry munificence—on a law‐abiding climate, a type of organizational climate related to unlawful conduct, and (b) the role of socially responsible organizational practices in combating these negative effects. Survey data were collected from 118 firms and analysed using OLS moderated regression. Our results indicate that a manager's perceptions of regulatory burden and lack of industry munificence are negatively related to the extent to which the firm has a law‐abiding climate. Furthermore, our findings shed light on the ability of socially responsible practices to countervail this effect. While the negative effect of perceived regulatory burden on law‐abiding climate weakens when codes of ethics are used more extensively by a firm, it strengthens when firms hold a CSR certification. The latter finding may be due to the lack of enforcement associated with the specific certification considered in our study.
