Abstract

Even though most previous research studies suggest that the relationship between common financial ratios and stock returns is linear, recent studies by Mramor and Mramor‐Kosta (1997), and Mramor and Pahor (1998) show that such a linear relationship might not generally exist. In this study, we model the relationships between common financial ratios and stock returns from 1996 to 2000 using linear and non‐linear forms for a sample of 46 Egyptian firms. Our empirical findings suggest that non‐linear relationships exist and are more descriptive of the behavior of stock returns.

Abstract

Purpose

The paper aims to the preparation of novel disperse dye based on azo salicylaldehyde derivatives TF-A [2-hydroxy-5-((3-(trifluoromethyl)phenyl)diazenyl)benzaldehyde] and full evaluation of their use as disperse dye TF-ASC [bis 2-hydroxy-5-((3-(trifluoromethyl)phenyl)diazenyl)benzaldehyde Schiff base with 4,4'-methylenedianiline] for dyeing polyester fabric at various conditions.

Design/methodology/approach

The dispersed dye was synthesized via Schiff base condensation in the presence of ceric ammonium nitrate cerium ammonium nitrate 10 mmole% as an eco-friendly catalyst at room temperature. The chemical structure of the prepared dye was characterized via elemental analysis, Fourier-transform infrared spectroscopy, 1H- and 13 C-NMR spectroscopic analysis tools. This study thoroughly examined the dyeing of disperse dye TF-ASC on polyester at various conditions. The characteristics of dyed polyester fabric were measured by colour measurements, as well as light, washing, crock fastness and finally, colour strength. The discrete fourier transform (DFT) theoretical studies, including EHOMO, ELUMO and optimized geometrical structure, were assumed and discussed in detail.

Findings

The results showed that the synthesized organic dye TF-ASC was highly functional and appropriate for this kind of dyeing method. The dyeing fabrics obtained from disperse dye TF-ASC, properties possess high colour strength as well as good overall fastness properties. These dyes had a high affinity for polyester fabric, with just a tiny change in dye affinity when the pH was changed, even under alkaline circumstances. The dye levelness and shade depth of the colour results were good, and there were a variety of hues from light brownish yellow to deep brownish yellow. The results obtained from DFT computational studies such as EHOMO, ELUMO, optimized structure, diploe moment µ and electrophilicity index deduced that prepared organic dye TF-ASC is more applicable as a dispersed dye.

Originality/value

This research is significant because it provides a new dye for dyeing polyethylene terephthalate fibres with exceptional brightness and levelness; the method of preparation is a useful pathway due to its being known as a green chemistry method.

Abstract

Purpose

The purpose of this paper is to unveil the main changes in the UAE’s policy towards Iran since its foundation in 1971. The UAE favored strategic hedging, extending its commercial and diplomatic relations with Iran, in addition to developing its military capabilities and maintaining military/security alliances with Saudi Arabia and the USA. However, the UAE started to reorient its policy towards Iran by adopting some sort of balancing strategy in the aftermath of the Arab Spring of 2011. This paper examines how and why the UAE had to change course and explores whether it would revert back to strategic hedging with Iran.

Design/methodology/approach

The study will be carried out based on a theoretical framework drawn from strategic hedging theory, a new structural theory in international relations, to examine the shifts in UAE policy towards Iran. Previous literature suggests that small states prefer hedging over balancing or bandwagoning. The authors also undertake a descriptive analysis and deploy a longitudinal within-case method to investigate changes in UAE policy towards Iran and identify the causal mechanisms behind these changes. That method allows investigating the impact of a particular event on a case by comparing the same case before and after that event occurred.

Findings

The main finding of this study is that the UAE hedging strategy towards Iran allowed maximizing the political and economic returns from the cooperation with Iran and mitigating the long-range national security risks without breaking up the consistent and beneficial ties with other regional and global powers. Hedging achieved the desired outcome, which is preventing direct military confrontation with Iran. Hard balancing, adopted by Abu Dhabi after the 2011 Arab Spring, has proved to have some negative effects, most importantly provoking Tehran. Some recent indicators suggest, though that the UAE may revert back to its long-established hedging policy towards Iran.

Originality/value

Strategic hedging is a new structural theory in international relation, although hedging behavior in states’ foreign policies is far from new. It is new enough, thus, not have been researched sufficiently, strategic hedging still needs theorizing and comparison. This paper highlights the importance of strategic hedging as the most appropriate strategy for small states. It provides an important contribution to the application of the theory to the case of UAE policy towards Iran. The paper also assesses the conventional wisdom that small states prefer hedging over balancing in the light of the changes in the UAE foreign policy since 2011.

Abstract

Purpose

This research paper aims to develop a comprehensive tourism satellite account‐human resource module (TSA‐HRM) which can complement and enhance the analytical capacity provided by the TSA, allowing for a broader insight into tourism's role in the economy, especially that of Egypt.

Design/methodology/approach

The objectives have been achieved through reviewing the literature in the fields of tourism satellite account (TSA) and its handling of tourism employment. To answer the research questions, one strategy and one method associated with the qualitative approach are used. The strategy refers to the case study, while the method refers to participant observation. An in‐depth analysis of the TSA project in Egypt was performed using the Data Quality Assessment Framework (DQAF) introduced by the International Monetary Fund.

Findings

The results indicate that statistics on tourism‐related employment in Egypt are usually fragmented, difficult to compare and often lack quality, credibility and reliability. Thus Egypt is in need of a way to improve tourism labor market statistics. However, the process of assessment of the TSA project in Egypt shows that Egypt has good experience in implementing the TSA system. The application of the TSA in Egypt at this high level will create a new horizon for improving the quality of tourism employment statistics.

Research limitations/implications

At the time of the research Egypt was in the process of constructing its first TSA, and this of course is considered one of the limitations. Since the introduction of TSA to the Egyptian tourism industry in 2009, the statistical system of tourism has made a considerable contribution to improve the quality of data, based on evaluating some of the DQAF criteria, but there are no results so far. The present situation caused the study to fall within the theoretical framework, without producing any statistics on tourism employment in Egypt according to the proposed TSA‐HRM.

Practical implications

The model proposed will provide detailed data about employment, labor or human resource issues related to tourism in the Egyptian economy, which provides a useful resource for planning policy and decision making.

Originality/value

Considering the research findings, the study developed a comprehensive quantitative (monetary and non‐monetary) and qualitative tourism human resources module of tourism satellite account to extend the analytical capacity of the TSA as well as trace most issues relevant to the tourism labor market in Egypt.

Abstract

Purpose

This study aimed to investigate the impact of total quality practices on knowledge management (KM) processes across a Social Security Corporation (SSC) in Jordan and explore the best approach to improve KM processes using quality management.

Design/methodology/approach

This study followed a quantitative methodology: a conceptual model was developed based on an extensive review of the related literature; an online survey was developed and distributed using the SSC's intranet; and 384 surveys were completed and used in the statistical analysis. The two-stage approach of structural equation modeling (SEM) was employed to analyze and interpret the data, and was used to validate the conceptual model of this research.

Findings

Based on the statistical analysis it was found that six out of seven independent factors relating to quality management practices were confirmed to have a significant impact on the knowledge management processes (KMPs). Building upon the findings an agenda for improving KM processes using quality management is proposed.

Originality/value

This study was conducted in one organization namely the SSC because it is the largest public service organization in Jordan and offers compulsory services. The inclusion of other public organizations and companies may reflect different findings. Future research may collect data from other service industries to get a more comprehensive perspective from developing countries such as Jordan. Moreover, the population of this study included only the General Director, General Director Assistants, and Administrative Managers. Front-line employees were excluded from the data collection because the study was conducted solely from a managerial perspective.

Abstract

Purpose

Design cost overrun is one of the prominent factor that can impact the sustainable delivery of the project. It can be encountered due to a lack of information flow, design variation, etc. thereby impacting the project budget, waste generation and schedule. An overarching impact of this is witnessed in the sustainability dimensions of the project, mainly in terms of economic and environmental aspects. This work, therefore, aims to assess the implications of a technological process, in the form of building information modelling (BIM), that can smoothen the design process and mitigate the risks, thus impacting the sustainability of the project holistically.

Design/methodology/approach

The identified design risks in construction projects from the literature were initially analysed using a fuzzy inference system (FIS). This was followed by the focus group discussion with the project experts to understand the role of BIM in mitigating the project risks and, in turn, fulfilling the sustainability dimensions.

Findings

The FIS-based risk assessment found seven risks under the intolerable category for which the BIM functionalities associated with the common data environment (CDE), data storage and exchange and improved project visualization were studied as mitigation approaches. The obtained benefits were then subsequently corroborated with the achievement of three sustainability dimensions.

Research limitations/implications

The conducted study strengthens the argument for the adoption of technological tools in the construction industry as they can serve multifaceted advantages. This has been shown through the use of BIM in risk mitigation, which inherently impacts project sustainability holistically.

Originality/value

The impact of BIM on all three dimensions of sustainability, i.e. social, economic and environmental, through its use in the mitigation of critical risks was one of the important findings. It presented a different picture as opposed to other studies that have mainly been dominated by the use of BIM to achieve environmental sustainability.
