Abstract

Propose

This paper aims to access the protective function of hybrid sol-gel coatings deposited on 304L stainless steel substrate in silane solutions containing a mixture of tetraethoxysilane, methyltriethoxysilane and glycidyloxypropyltrimethoxysilane with different pH values during various immersion periods.

Design/methodology/approach

The 304L stainless steels coated through 10 and 30 s of immersion in the silane solutions with pH values of 2.1 and 2.8 were exposed to NaCl solution. The corrosion resistance of the coated substrates was studied through taking advantage of electrochemical noise method as well as atomic force microscopy (AFM), water contact angle and field emission-type scanning electron microscopy (FESEM) surface analysis.

Findings

The electrochemical current noise, PSD (I) plot, noise resistance and characteristic charge as parameters extracted from electrochemical noise method indicated the superiority of eco-friendly silane coating deposited on the substrate surface during 10 s exposure to the solution, due to the film uniformity and homogeneity as confirmed by FESEM and AFM. Moreover, immersion of the stainless steel in the silane solution with pH 2.1, characterized by higher hydrolysis ratio, led to more effective corrosion control in the NaCl electrolyte according to the results of electrochemical noise and FTIR measurements.

Research limitations/implications

The noise resistance and characteristic charge as electrochemical noise parameters were only used in this research to evaluate the protective behavior of the water-based silane sol-gel coatings. Future studies should examine the correlation between electrochemical noise data and the parameters extracted from other electrochemical methods, e.g. electrochemical impedance spectroscopy.

Practical implications

The data obtained in this research may provide an effective approach based on electrochemical noise method to screen the silane sol-gel coatings for protection of metallic substrates against corrosion.

Originality/value

According to the literature, no report can be found studying the effect of immersion time on a silane solution, including glycidyloxypropyltrimethoxysilane, tetraethoxysilane and methyltriethoxysilane, as well as the silane solution pH on the corrosion resistance of 304L stainless steel in NaCl solution through electrochemical noise method.

Abstract

Purpose

The provision of private health-care services by public hospitals is common in Iran. Examining factors associated with patients’ preferences to use private health services and using this knowledge in health planning and policymaking can help expand the use of such services. Thus, this study aims to investigate patients’ preferences for private health services delivered in public hospitals.

Design/methodology/approach

Based on a discrete choice experiment from a sample of 375 patients in a public training hospital in Qazvin, northwest city of Iran, the authors evaluated participants’ preference over the health-care attributes affecting their choice to use private health-care services delivered in the hospital. The authors also estimated the marginal willingness to pay to determine the maximum amount a patient was willing to pay for the improvement in the level of each health-care attributes.

Findings

The findings revealed that patients were 2.7 times more likely to choose private hospital services when the waiting time was reduced to less than a week. Furthermore, as patients had complimentary insurance coverage, they were over 60% more likely to receive such services from training hospitals. Finally, continuity of care and reduced health-care tariffs were significant factors that increased patients’ preference to choose private services by 52 and 37%, respectively.

Originality/value

Examining factors associated with patients’ preferences to use private health services and using this knowledge in policymaking can help expand such services. The findings affirmed that various incentives, including service quality factors, are required to increase the likelihood of patients choosing private services.

Abstract

Purpose

The purpose of this paper is to develop a framework of sustainable service supply chain management (SCM) processes and practices in the multi-dimensional construct. It tries to provide a template for those sustainability general key practices that can be scheduled and budgeted in different service sectors.

Design/methodology/approach

To provide an applicable framework, its adaptability to most service settings should be ensured. In this regard, at first, the related literature on service SCM processes and sustainability practices of SCM are reviewed. To modify and confirm the extracted list, it is distributed to experts. After summarizing experts’ opinions, an initial list of the sustainable service supply chain practices (SSSCPs) is provided. Finally, the Fuzzy Delphi Method is applied to construct the framework for hospital supply chain (SC).

Findings

It suggests that the SSSCPs can be constructed in terms of seven major processes: managing the sustainable supplier, sustainable employee, sustainable customer, sustainable service performance, sustainable service operations, sustainable external relations, and sustainable knowledge, information and technology.

Practical implications

The framework can be employed as a template of sustainability practices for individual member firms of service SCs to identify and implement the key practices toward sustainability.

Originality/value

Reviewing the literature indicates that determining what is unique about the sustainable SCM in the service sector is immature. The paper is a preliminary effort to identify the general sustainability practices, in incorporating all sustainability dimensions in service SC processes.

Abstract

Purpose

The purpose of this paper is to contribute the advancement of knowledge on food heritage and indigenous entrepreneurship in a non-Western country, specifically in the Persian gardens as the touristic destination for increasing the tourism and food businesses in Iran.

Design/methodology/approach

The methodological approach adopted is based on qualitative and quantitative approaches to compare two representative gardens named as Bagh-Chehel-Sotoun and Bagh-Fin, as famous examples of a Persian garden in Iran. The methods supported the research to explain the lack of strategies for improving virtuous cycles in Persian gardens despite their potentials as the main places to attract many tourists.

Findings

Regarding local food and the quality of servicing, most of the visitors and tourists (85–90%) had interest to test local and traditional foods around both gardens, but they had no sufficient awareness of Iranian traditional foods. According to the tourists’ interests, the authors concluded the lack of servicing and facilities to present and introduce local and traditional food for tourists.

Research limitations/implications

Despite the limitation of local food services and lack of awareness of tourists about local foods, the implication of the study offers possible avenues to promote local food business.

Practical implications

The results could be useful for cultural heritage and tourism organizations and for investors in the economic sector due to more exploitation of the tourism industry.

Originality/value

The paper is the first work evaluating the Persian garden with a new perspective of local foods in Iran.
