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.     

Board gender diversity and transparency of environmental,social and governance disclosure: Evidence from Malaysia

This study aims to investigate the effect of board gender diversity on the transparency of environmental, social, and governance (ESG) disclosures in an emerging market such as Malaysia. Dataset is comprised of 568 firm-year observations from 78 firms listed on the Bursa Malaysia. Ordinary least squares regression analysis of the data shows that ESG disclosure scores are significantly improved with the increasing presence of women directors on corporate boards. However, when the individual components are studied, the impact of board gender diversity varies. This study contributes to the limited but growing literature on ESG reporting quality and board gender diversity especially in emerging economies.     

R&D capabilities,intellectual property strength and choice of equity ownership in cross-border acquisitions: evidence from BRICS acquirers in Europe

The aim of the study is to investigate two relatively underexplored factors, namely, the R&D (research and development) capabilities of target firms and the strength of intellectual property (IP) institutions in target economies, that influences the choice of equity ownership in cross border acquisitions (CBAs) undertaken by multinational enterprises (MNEs) from BRICS (Brazil, Russia, India, China and South Africa) economies. They developed the key hypothesis on foreign market entry through CBAs by incorporating insights from transaction costs economics, the resource-based view and institutional theory to investigate the determinants of full versus partial equity ownership. Using logistic regression estimation methods to a sample of 111 CBA deals of BRICS MNEs in 22 European countries, it was found that BRICS MNEs were likely to pursue full rather than partial acquisition mode when target firms have high R&D capabilities. However, the greater the degree of strength of IP institutions in target economies and higher the target firms’ R&D capabilities, the more likely it is for BRICS MNEs to undertake partial, rather than, full acquisition mode. They provided interesting theoretical insights and managerial implications that might underlie some of the key findings on CBAs by emerging market MNEs.

Creating a Sustainable Supply Chain Network by Adopting Relationship Management Strategies

ABSTRACT

Purpose: This paper develops a conceptual framework to analyze the impact of a supply chain network (SCN) structure on relationship management strategies (RMS) that focal firms apply to manage sustainability issues within the SCN.

Design/methodology/approach: This paper is based on a comprehensive review and analysis of the industrial marketing and purchasing (IMP), sustainable supply chain management (SSCM), and SCN literature.

Findings: The conceptual framework expands the network perspective in the SSCM context by considering the important role of the SCN structure in the firm’s decision-making process. Four factors (dependency, distance, power, and transparency) were found that are useful in conceptualizing the SCN structure. The conceptual framework also categorizes various sustainability practices into four RMS (noncompliance, transactional, dictatorial, and collaborative), which are needed to make an SCN more sustainable. In addition, 16 propositions are developed based on how firms may identify the most effective RMS to implement appropriate sustainability practices through examining their SCN structure.

Research limitations/implications: The conceptual framework, developed as a result of a comprehensive review of the literature, led to the development of 16 propositions, which can assist in furthering a research agenda on RMS to diffuse various sustainability practices within SCN structures.

Originality/value: The relationship between SCN structure and RMS in the sustainability context remains an under-researched but emerging area of interest. This paper leverages existing research to develop a conceptual framework suitable for empirical testing.
