Abstract

Purpose

Evidence suggests that a growing number of consumers across the world are becoming more environmentally responsible in terms of their personal habits and lifestyles. In this paper, the authors aim to use both parametric and non-parametric econometric models to estimate Kuwaiti consumers’ willingness to pay (WTP) for environmental protection in Failaka island.

Design/methodology/approach

Contingent valuation methods based on log-logistic and log-normal regression models revealed that consumers in Kuwait are willing to pay a price premium of approximately 40 Kuwaiti dinars for environmental protection in Failaka island based on the double-bound dichotomous choice model.

Findings

Socio-economic variables have no significant influence on the respondent’s WTP. As expected income has a positive relationship with WTP and bid price has negative relationship with WTP to protect the environment in Failaka island.

Originality/value

This study highlight the fact that understanding consumers’ environmental-friendly behaviors may play an important role in formulating environmental policy changes to face complex problems as diverse as environmental pollution or environmental degradation.

Abstract

Purpose

This study aims to explore the hijab research impactful authors, influential journals, collaboration networks and emerging trends. In addition, keyword co-occurrence techniques are used to scrutinize the field’s major schools of thought.

Design/methodology/approach

Hijab research has witnessed a distinct proliferation during the past decade. In this article, the authors apply bibliometric network techniques to examine the conceptual/intellectual structure of this domain based on 485 Web of Science documents written by 848 authors representing 66 nations and spanning almost 40 years (1984–2021).

Findings

Results show that the most impactful journals publishing hijab research are Women’s Studies International Forum, Gender, Place and Culture, Ethnic and Racial Studies and the Journal of Islamic Marketing. Results also show that the author collaboration network in hijab research is sparse. Furthermore, results related to collaborative networks between institutions and countries reveal a global “North–South” schism between developed and developing nations. Finally, the multiple correspondence analysis applied to obtain the hijab research conceptual map reflects the depth and breadth of the field’s foci.

Originality/value

The present analysis has far-reaching implications for aspiring researchers interested in hijab research as the authors retrospectively trace the evolution in research output over the past four decades, establish linkages between the authors and articles and reveal trending topics/hotspots within the broad theme of hijab research.

Abstract

Purpose

This study aims to apply novel anticorrosive pigments containing silica fume-phosphates (Si-Ph), which were prepared using core-shell technique by covering 80-90 per cent silica fume (core) with 10-20 per cent phosphates (shell) previously, to play dual functions simultaneously as anticorrosive pigments in coating formulations and as an anticorrosive admixture in concrete even if it is not present in the concrete itself. Two comparisons were held out to show the results of coatings on rebars containing core-shell pigments in concrete, and concrete admixtured with silica fume can perform a dual function as anticorrosive pigment and concrete admixture. The evaluation of corrosion protection efficiency of coatings containing core-shell pigments and those containing phosphates was performed.

Design/methodology/approach

Simple chemical techniques were used to prepare core-shell pigments, and their characterization was carried out in a previous work. These pigments were incorporated in solvent-based paint formulations based on epoxy resin. Different electrochemical techniques such as open-circuit potential and electrochemical impedance spectroscopy were used to evaluate the anticorrosive efficiency of the new pigments.

Findings

The electrochemical measurements showed that concrete containing coated rebars with core-shell pigments exhibited almost similar results to that of concrete admixtured with silica fume. Also, the anticorrosive performance of coatings containing Si-Ph pigments offered protection efficiency almost similar to that of phosphates, proving that these new pigments can perform both roles as anticorrosive pigment and concrete admixture.

Originality/value

Although the new Si-Ph pigments contain more than 80 per cent waste material, its performance can be compared to original phosphate pigments in the reinforced concrete.

Abstract

Purpose

This paper aims to examine the structure and dynamics of scholarly publications dealing with Wikipedia. The research also aims to investigate how such research evolved since its launch in 2001.

Design/methodology/approach

Wikipedia has grown to be the biggest online encyclopedia in terms of comprehensiveness, reach and coverage. Based on 1,040 PubMed Wikipedia documents written by 5,280 authors over two decades (2001–2021), this paper conducts a bibliometric review of the intellectual structure of scholarly publications dealing with Wikipedia.

Findings

Results show that annual scholarly publications on Wikipedia growth rate is 13.26. Major outlets publishing Wikipedia’s research are PloS One, the Journal of Medical Internet Research, Nucleic Acids Research, Studies in Health Technology and Informatics, Bioinformatics and the International Journal of Medical Informatics. Results also show that the author collaboration network is very sparse, signifying rather negligible collaboration among the authors. Furthermore, results reveal that the Wikipedia research institutions’ collaboration network reflects what is sometimes termed Wikipedia’s “North-South divide,” indicating limited collaboration between rich and poor nations’ institutions. Finally, the multiple correspondence analysis applied to obtain the Wikipedia research conceptual map and its intellectual structure reveals the intellectual thrust and the diversity of the scholarly publications dealing with Wikipedia.

Originality/value

To the best of the author’s knowledge, this research represents the first application of bibliometric methods to investigate two decades of scholarly publications dealing with Wikipedia based on the PubMed database.

Abstract

Purpose

This purpose of this paper is to clustering Kuwaiti consumers choice of Sharia-complaint financial products and services based on several factors such as religiosity, financial knowledge, customer value, satisfaction, trust, service quality, relationship with service providers and innovation.

Design/methodology/approach

The study uses self-organizing maps, a neural network technique, in order to cluster and segment consumers of Sharia-compliant financial products and services in Kuwait. From a marketing perspective, SOM can be viewed as a flexible clustering technique in which different clusters are identified without the rigid traditional statistical assumptions of linearity or normality.

Findings

This paper shows that consumers of Sharia-compliant financial products in Kuwait can be clustered into three distinct segments: enthusiasts, laggards and rejectors. The enthusiasts represent the largest cluster with a frequency of around 66 percent, while the Rejectors represent the smallest segment with a frequency of 10 percent.

Originality/value

This paper advances our knowledge about the behavioral aspects of financial consumer choice within a non-traditional Sharia-compliant financial products context.

Abstract

Purpose

Using organic coatings serves as a key method to protect metal structures against corrosion. Attempts have been made to improve the corrosion inhibition of the coatings using novel types of pigments. This study aims to study the application of organic coatings containing rice straw (RS) waste as anticorrosive pigment for corrosion protection of reinforced steel. The RS was used by precipitating a thin layer of ferrite pigments on its surface to improve their characteristics and corrosion resistance activity.

Design/methodology/approach

The evaluation of corrosion behavior of coated reinforced steel with paints containing these novel pigments is reported using different electrochemical methods.

Findings

The coatings containing the new prepared RS-ferrite pigments offered good corrosion protection, and coatings containing RS-ZnFe showed the best protection performance.

Originality/value

This paper introduces novel method to prepare treated RS without any burning and to play the role of pigments in anticorrosive paint formulations based on its silica content.

Abstract

Purpose

The purpose of this paper is to examine female fashion consumer profiles in Kuwait. Drawing on symbolic interactionist, fashion adoption theory, the trickle-down theory, the collective selection theory and the mass-market theory, this study examines the influence of self-identity, social interactions and prestige consumption on Kuwait female apparel consumers.

Design/methodology/approach

The study applies self-organizing maps (SOM), discriminant and multiple correspondence analyses to analyze the influence of self-identity, social interaction and prestige consumption on Kuwaiti female apparel consumers.

Findings

Results unveiled three distinct clusters: liberals, traditionalists and conservatives. Liberals include students, singles with a low income, less than KD 500. They are younger and wear neither Abaya nor Hijab. Traditionalists include employees, mixed between married and divorced females. They have moderate income between KD 500–1,500, two age groups between 25–30 and 31–35 years. Finally, conservatives include older females of age 36–45 years. They are housewives with a high-income of more than KD 1,500, and wear both Abaya and Hijab. Findings seem to confirm that the younger generations of females in Kuwait are by far living a different life than their mothers and grandmothers. Findings also show that culture, especially religion and traditions, is still exercising an enduring influence on Kuwaiti females purchasing behavior.

Originality/value

This study extends the existing literature dealing with female apparel consumption by applying cluster analysis to an Arab country, which makes it possible to generalize results to other Arab nations. Second, the author uses SOM along with traditional clustering methods to check the robustness of findings.

Abstract

Purpose

New types of phosphate pigments which are appropriate alternatives for hazardous chromate pigments have been prepared and evaluated. These new pigments were prepared via a new technique named core-shell. The core-shell materials consist of at least two separate phases with different chemical compositions. Recently, these materials have become more significant because they have the advantage of gathering the properties of both cores and shells that help to overcome the defects that they might possess individually. The purpose of this research is to develop a modified silica fume-phosphate core-shell pigment that contains 80-90 per cent of waste material (silica fume) and at the same time can offer promoted mechanical and anticorrosive properties than silica fume and they can also be compared with phosphates. The pigments have shells of Zn, Mn, Zn.Mn phosphates comprising about 10-20 per cent.

Design/methodology/approach

The prepared core-shell pigments have been characterized using several methods, which have then been integrated in alkyd paint formulations. The physical and mechanical properties of dry films and their corrosion prevention using accelerated laboratory test in 3.5 per cent NaCl for 28 days are estimated.

Findings

This study showed that the performance of these new pigments is highly efficient in corrosion protection, and it can be a suitable alternative to phosphate pigments despite containing phosphates which does not exceed 20 per cent of the composition.

Practical implications

Waste materials were reused in paints and only simple modification was used; their effectiveness was high and can be compared with well-known pigments.

Originality/value

Silica-phosphate core-shell pigments are environmentally friendly pigments that can replace other hazardous pigments (e.g. chromates and phosphates) with almost the same quality in their performance.

Abstract

Purpose

This study aims to examine the impact of Covid-19 on transforming accountability, corporate social responsibility (CSR) and office operation and control. This paper explains how unleashing the rationality of health and safety along with internal CSR made the transformation to telework successfully operable in a periphery of a western multinational corporation.

Design/methodology/approach

The study draws upon the theories of governmentality and social accountability. It adopts an interpretative qualitative research approach and uses the case study method. Data were collected from one of the biggest private sector telecommunication companies in Egypt.

Findings

This study finds that Covid-19 and its related health and safety discourse represented a good rationale for the western home office to accelerate the initiation of its office transformation plan to reach full working from home policy in a less developed country peripheral subsidiary. Under the guise of CSR, the company spent a large budget to make this transformation quickly operable, while its Egyptian subsidiary is financially distressed. Moreover, the company achieved its objectives from this new rationality as employees currently prefer the telework mode which reduces the company costs in the long run.

Practical implications

The study provides practitioners with evidence and practicable knowledge regarding the impact of Covid-19 on office reconfiguration and the ways used to achieve this in the Egyptian telecommunication sector.

Originality/value

The current study extends the governmentality literature by illustrating that transformation to telework in emerging markets is an operational manifestation of cost reduction and efficiency rationality under the guise of CSR. Moreover, it extends the office transformation literature by bringing early evidence regarding office transition plans during COVID-19 in an emerging market.

Abstract

Purpose

Long time ago, multistructured materials showed great interest being considered as the bridge between bulk and atomic materials. Core-shell particles are kind of composite materials that refer to multilayered structures with a core totally surrounded by shell(s) (onion-like structure). These new structures can offer an advantage of applying new adjustable parameters like shape, stoichiometry and chemical ordering, in addition to the opportunity of tailoring more complexed structures for different applications. Recently it was found that these structures can be tuned and taken for more advanced path with novel structures formed of core surrounded by multishells. The purpose of this study is to study the effect of the new anticorrosive pigments with its mutual shells and how each shell affects the performance of the pigment in protecting the metal and which shell will be more relevant in its effect.

Design/methodology/approach

The prepared pigments were characterized using X-ray fluorescence, X-ray diffraction, TEM and SEM/EDX to prove their core-shell structure, and then they were integrated in coating formulations to evaluate their anticorrosive activity using immersion test and electrochemical impedance spectroscopy (EIS).

Findings

The results showed that the prepared core-shell pigments possess a lot of unique characteristics and can offer improved anticorrosive performance in the generated coatings.

Originality/value

Core-mutual shells structured pigments were prepared for improving the corrosion resistivity of the organic coatings as a new trend in anticorrosive pigments.
