Abstract

Purpose

The paper uses firm level data for the top listed firms in New York exchange stock over the period 2000–2017. The analysis is mainly based on 237 firms that already experienced losses at the end of the fiscal year. The study aims to use the properties of the dynamic panel data, specifically the methodology proposed by Arenllo and Bond (1991), to fulfill the objectives of the paper.

Design/methodology/approach

This paper focuses on the dividend policy management of the firms when they experience a loss at the end of the fiscal year. The objective is to examine how such a policy management affects the sustainability of the firm (measured by the future sales and total factor productivity[TFP]) and the wealth of its shareholders (measured by the Stock Returns).

Findings

The results show that the distressed firms that distribute dividends at the end of the loss period are able to maintain sustainability and to reach more favorable wealth situation of their shareholders relative to the firms who abstain to pay; the dividend policy during periods of loss is still able to send positive signals about the firm in the market; and the dividend policy can be considered as a predictive indicator for a sustainable firm whose shareholders can also predict their capital gains.

Originality/value

Agreed upon the literature that the firms during the period of crisis are likely to change their dividend policy, this study offers robust evidence that the dividend policy of distressed firms affects their sustainability (measured by sales and TFP) and the wealth status of their shareholders (measured by the Stock Returns).

Abstract

Purpose

This paper examines the impact of cryptocurrency market on the stock market performance in Middle East and North Africa (MENA) region. A comparative analysis is extended to distinguish this impact between Gulf countries and other economies in the region.

Design/methodology/approach

The analysis uses the information of cryptocurrencies and the stock market indices of the Gulf countries for the period 2014–2018 on a daily basis. Two strategies have been implemented to fulfill the goal of the study: first, the tests strategy, which is applied using the cointegration analysis and panel-specific forms of Granger causality; second, the regression strategy, which is applied mainly using the instrument variable with generalized method of moments (IV-GMM) method.

Findings

The results show that there is a significant relationship between the cryptocurrency market and the stock market performance in the MENA region. On the one hand, for the Gulf countries that claim full obedience to the Islamic Sharia rules, each 1% increase in the cryptocurrency returns reduces the stock market performance by 0.15%. On the other hand, for the non-Gulf (other MENA) countries that have flexibility in applying the Islamic Sharia rules or do not follow it, the stock market performance increases by 0.13%, for each 1% increase in the cryptocurrency returns.

Originality/value

The paper proposes two main contributions: First, the paper introduces the cryptocurrency returns as one of the determinants of the stock market performance in the MENA region. This impact is distinguished based on the degree of applying the Islamic Sharia rules and the vision of the government to the stock market. Second, the paper provides an empirical guideline for governments in the MENA region for efficient measures in their stock market, given the important expansion of the cryptocurrency market and the government type.

Abstract

Purpose

The purpose of this paper is to explore the relationship between organizational learning and patient safety culture in hospital pharmacy settings as determined by the learning organization survey short-form (LOS-27) and pharmacy survey on patient safety culture instruments, and to further explore how dimensions of organizational learning relate to dimensions of pharmacy patient safety culture.

Design/methodology/approach

This study is a cross-sectional study. Data were obtained from three public hospital pharmacies and three private hospital pharmacies in Kuwait. Partial least square structural equation modeling was used to analyze the data.

Findings

A total of 272 surveys (59.1 percent response rate) were completed and returned. The results indicated a significant positive relationship between organizational learning and patient safety culture in hospital pharmacy settings (path coefficient of 0.826, p-value <0.05 and R2 of 0.683). Several dimensions of the organizational learning showed significant links to the various dimensions of the pharmacy patient safety culture. Specifically, training (TRN), management that reinforces learning (MRL) and supportive learning environment (SLE) had the strongest effects on the pharmacy patient safety culture dimensions. Moreover, these effects indicated that MRL, SLE and TRN were associated with improvements in most dimensions of pharmacy patient safety culture.

Originality/value

To the best of the authors’ knowledge, this is the first attempt to assess the relationship between organizational learning, patient safety culture and their dimensions in hospital pharmacy settings.

Abstract

Purpose

The purpose of this paper is to formulate a specialized artificial neural network algorithm utilizing radial basis function (RBF) for modeling of time to failure of aircraft engine turbines.

Design/methodology/approach

The model uses training failure data collected from operators of turboprop aircraft working in harsh desert conditions where sand erosion is a detrimental factor in reducing turbine life. Accordingly, the model is more suited to accurate prediction of life of critical components of such engines. The used RBF employs a closest neighbor type of classifier and the hidden unit’s activation is based on the displacement between the early prototype and the input vector.

Findings

The results of the algorithm are compared to earlier work utilizing Weibull regression modeling, as well as Feed Forward Back Propagation NN. The results show that the failure rates estimated by RBF more closely match actual failure data than the estimations by both other models. The trained model showed reasonable accuracy in predicting future failure events. Moreover, the technique is shown to have comparatively higher efficiency even with reduced number of neurons in each layer of ANN. This significantly decreases computation time with minimum effect on the accuracy of results.

Originality/value

Using RBF technique significantly decreases the computational time with minimum effect on the accuracy of results.

Abstract

Purpose

This study aims to provide a collaborative supply chain system using a combination of two already existed methods, i.e. levels of decision-making and supply chain operation reference (SCOR).

Design/methodology/approach

A two-phase methodology was conducted based on field analysis and survey analysis. Field analysis included a critical analysis of literature related to supply chain performance measurement and identified related indicators.

Findings

In a survey analysis, a questionnaire was developed to test the established indicators from managers and employees of manufacturing companies. It formulated a novel model for the performance measurement of the supply chain (SC) which included 4 factors (customer, efficiency, flexibility and product), with a total of 31 sub-components.

Originality/value

The structure provides a tied horizontal (SCOR) and vertical (progressive decision) in relation to the features that characterize the SC performance. This system enables the decision-makers to make decisions at the strategic, tactical and operational levels. It reflects the performance measures reliability, authenticity and its application in various SC. It also improves communication with the regional party while ensuring a preventive schedule for maintenance.

Abstract

Purpose

The purpose of this paper is to investigate the interrelationships among knowledge management (KM), information systems (IS) and employees’ empowerment (EE) on employees’ performance (EP).

Design/methodology/approach

Accordingly, a structural model is developed that delineates the interactions among these constructs and explores the mediating effect of EE on the relationship between KM, IS and EP. A questionnaire-based survey was designed to test the aforementioned model based on dataset of 287 employees’ pharmaceutical industries in Jordan. The model and posited hypotheses were tested using structural equation modeling analysis.

Findings

The results indicated that KM and IS positively and significantly affect EE, in which the latter impact EP as well. However, neither KM nor IS proved to be positively related to EP. Additionally, EE positively and significantly mediated the relationship between KM and EP, besides the relationship between IS and EP.

Originality/value

This is one of the few studies which investigate the interrelationships among KM, IS and EE on EP, and the first to test the model on companies in the pharmaceutical industries in Jordan.

Abstract

Purpose

The purpose of this paper was to test the extract of barley as an environmentally friendly inhibitor for the acid corrosion of steel due to its wide availability as a popular major crop and its richness with different chemical constituents reported in literature (40) like alanine, glycine, serine, aspartic acid, leucine, valine, tyrosine and isoleucine with various number of functional groups that are able to chelate metal cations and to discuss the effect of temperature on its inhibition efficiency.

Design/methodology/approach

Electrochemical impedance spectroscopy (EIS) and polarization measurements were carried out using frequency response analyzer Gill AC instrument. The frequency range for EIS measurements was 0.1 ≤ f ≤ 1 × 103 with an applied potential signal amplitude of 10 mV around the rest potential. Polarization measurements were carried out at a scan rate of 30 mV/min, utilizing a three-electrode cell. A platinum sheet and saturated calomel electrode were used as counter and reference electrodes, respectively. The working electrode was constructed with steel specimens that have the following composition (weight per cent): C, 0.21; S, 0.04; Mn, 2.5; P, 0.04; Si, 0.35; and balance Fe.

Findings

Barley extract could act as an effective corrosion inhibitor for the acid corrosion of steel. The inhibiting action of the barley extract was attributed to its adsorption over the metal surface that blocks the available cathodic and anodic sites. Adsorption isotherms indicated that the adsorbed extract molecules cover one active center over the metal surface.

Originality/value

The research included the first use of an important world crop as an effective corrosion inhibitor that can reduce the corrosion of steel to an extent of 94 per cent.
