Abstract

Purpose

The current generation of light wave systems benefit from increased transmission distance by using optical amplification and increased capacity by using dense wavelength division multiplexing (DWDM) technology. The reach of present systems is limited by the noise contributed by the used amplifiers, combined with nonlinear effects from transmission. This paper aims to address these issues.

Design/methodology/approach

The nature and extent of degradations in the optical DWDM systems due to these limiting factors have been discussed in this paper.

Findings

It has been learnt that stimulated Raman scattering (SRS), four wave mixing (FWM) and amplified spontaneous emission (ASE) are the important factors in optical DWDM systems. These factors limit the system capacity of the transmission systems drastically.

Originality/value

It can be concluded from the discussion that while designing an efficient DWDM system, an optimization of the channel separation and the amplifier separation is required to minimize the nonlinear effects (FWM and SRS) along with the ASE noise introduced by inline optical amplifications.

Abstract

Purpose

Fiber nonlinearities are anticipated to impose transmission limitations due to the enhanced total interaction length in long‐haul dense wavelength division multiplexing (DWDM) optical transmission systems. The purpose of this paper is to analytically study the combined effect of stimulated Raman scattering (SRS) and four‐wave mixing (FWM) in the presence of amplified spontaneous emission (ASE) noise generated by erbium‐doped fiber amplifiers (EDFAs).

Design/methodology/approach

The paper presents analytical analysis of DWDM optical transmission systems in the presence of two significant fiber nonlinearities (SRS and FWM).

Findings

Simple expressions are derived to study the dependence of signal‐to‐noise ratio (SNR) on the amplifier spacing between two consecutive amplifiers.

Originality/value

The authors have analytically studied the combined effect of SRS and FWM in the presence of ASE noise generated by EDFAs. The novelty of the work is that it has considered all the three factors simultaneously and the expressions are derived for calculation of SNR.

Abstract

Purpose

This study aims to simultaneously examine the interrelated influence of antecedents involved in developing fast-food restaurant customer loyalty. A conceptual model which incorporates service quality attributes, price fairness, customer satisfaction, brand image and trust and the resultant effect on customer loyalty is proposed to better understand how fast-food restaurant customer loyalty can be optimized.

Design/methodology/approach

A quantitative research methodology adopting structural equation modelling was used to understand the interrelatedness and influence of antecedents involved in optimizing fast-food restaurant customer loyalty.

Findings

The findings indicate that service quality attributes (food quality and employee service quality) and price fairness significantly influence customer satisfaction and brand image, while physical environment quality has no significant influence. Additionally, customer satisfaction was found to influence brand trust and customer loyalty, while the brand image does not influence customer satisfaction but does influence brand trust and customer loyalty.

Practical implications

Understanding the interrelatedness and influence of antecedents involved in developing fast-food restaurant customer loyalty would enable academics and practitioners to formulate honed marketing and operational strategies to optimize customer loyalty and fast-food restaurant profitability.

Originality/value

This research addresses the paucity of research and marketing gaps regarding the interrelatedness and influence of antecedents involved in optimizing fast-food restaurant customer loyalty in Small Island Developing States (SIDS).

Abstract

Purpose

This study aims to analyze how various contingencies within the contingency theory influence the entrepreneurial orientation (EO) elements and performance of retail franchisees in a South Pacific Island nation.

Design/methodology/approach

This study employs a quantitative approach of data collection from 203 managers in a total of 89 retail franchise outlets. Convenience and snowball sampling techniques were used with data analysis through SPSS AMOS and covariance-based structural equation modelling (CB-SEM).

Findings

The results confirmed that technology, innovation and promotion; competitive edge and value co-creation; high return opportunity capitalization; and empowerment and support influenced franchisee performance, while responsive customer focused leadership and competitor knowledge proved to be insignificant. The findings supported EO's influence on both financial and non-financial indicators, with greater influence on financial indicators. The result revealed that EO accounts for partial impact on franchisee performance, while the remaining impact could be attributed to organization and environment contingencies.

Originality/value

The study proposes a novel context of EO in franchising, where we dissect key elements within the EO dimensions. It also adds to the extant literature on how the broader context of environmental and organizational factors termed as “strategic fit” affects entrepreneurial franchisee performance.

Abstract

Purpose

This study defines a three-angled research plan to intensify the knowledge and development undergoing in the retail sector. It proposes a theoretical framework of the customer journey to explain the customers' intent to adopt artificial intelligence (AI) and machine learning (ML) as a protective measure for interaction between the customer and the brand.

Design/methodology/approach

This study presents a research agenda from three-dimensional online search, ML and AI algorithms. This paper enhances the readers' understanding by reviewing the literature present in utilizing AI in the customer journey and presenting a theoretical framework.

Findings

Using AI tools like Chatbots, Recommenders, Virtual Assistance and Interactive Voice Recognition (IVR) helps create improved brand awareness, better customer relationships marketing and personalized product modification.

Originality/value

This study intends to identify a research plan based on investigating customer journey trends in today's changing times with AI incorporation. The research provides a novel model framework of the customer journey by directing customers into different stages and providing different touchpoints in each stage, all supported with AI and ML.

Abstract

Purpose

This paper aims to identify factors that influence customers' panic buying behavior during the COVID-19 pandemic.

Design/methodology/approach

A self-administered questionnaire was distributed to 357 participants in Fiji, and structural equation modeling to analyze the collected data.

Findings

Results indicate that expected personal outcomes is positively associated with customers' attitudes while expected community-related outcomes negatively impact customers' attitudes. Factors such as attitude, subjective norms, scarcity, time pressure and perceived competition were found to positively influence customers' panic buying intention. Furthermore, scarcity and time pressure were confirmed to positively influence perceived competitiveness while perceived social detection risk negatively influences customer's panic buying intention.

Practical implications

The findings highlight the need for better measures to ensure that every customer has access to goods and services and is not deprived of such necessities in times of a crisis. These results will assist store managers and policymakers in introducing better management, social policies and resource utilization mechanisms to mitigate panic buying during the pandemic.

Originality/value

This study's findings contribute to the literature on customer's panic buying behavior during a global pandemic. Research in this area remain scarce, inconsistent and inconclusive. Novel insights are generated as this study is the first to combine the theory of planned behavior, privacy calculus theory and protection motivation theory. Applying these theories allows new relationships to be tested to better understand customer behavior during a global pandemic. With most studies on customer behavior during crises and disasters in developed countries, this study generates new insights by exploring customer behavior in a developing country.

Abstract

Purpose

This study aims to find, analyse and synthesise the body of literature on how different health-care businesses form business-to-business (B2B) alliances. By doing so, this study seeks to identify visible research gaps to suggest future research questions and develop a conceptual framework to set a future research agenda.

Design/methodology/approach

The study uses the time-tested systematic literature review method to identify 57 studies that have addressed B2B relationships in the health-care industry. Thereafter, a qualitative analysis is performed to delineate the research profile and synthesise the key themes examined in the selected studies.

Findings

The qualitative analysis uncovers two key thematic foci: types and purposes of B2B relationships and pertinent issues in continued B2B relationships. Within these themes, the authors highlight different types of firms and their reasons for engaging in B2B relationships. The authors also summarise various issues that these firms deal with in such relationships. Finally, the authors highlight the limitations in the existing research and suggest future research questions to address them. The findings are summarised in a conceptual framework.

Originality/value

Although several reviews exist that evaluate the state-of-the-art research on B2B relationships, very few have examined the same in the context of health care. This review adds value to the research by providing a comprehensive overview of the existing findings in the area to encourage future research through a conceptual framework.

Abstract

Purpose

The purpose of this study is to explore the factors affecting locals’ domestic gastronomic behaviour. A conceptual framework is developed that examines domestic restaurant coolness, social return and tourism ethnocentrism as antecedents to attitude towards domestic gastronomic tourism, while positive word-of-mouth and domestic gastronomy behaviour are modelled as consequences.

Design/methodology/approach

The study adopts a quantitative methodology to conduct a cross-national examination in Italy and Fiji. A total of 621 responses (Italy = 302 and Fiji = 319) were collected through an online survey and analysed using covariance-based structural equation modelling.

Findings

The results of this study show that the positive relationship between domestic restaurant coolness and tourism ethnocentrism on attitude is stronger for Italy. The positive relationship between social return and attitude is only significant for Fiji. Moreover, the positive relationship between attitude towards domestic gastronomic tourism and positive word-of-mouth is stronger for Fiji. Finally, the positive relationship between attitude towards domestic gastronomic tourism and domestic gastronomic tourism behaviour, while significant in both countries, depicted no significant differences in results.

Practical implications

The findings of this study highlight the need for building a cool image based on vibrant, iconic, rebellious and authentic attributes. Marketers need to focus on local restaurants’ effective use of social media platforms to increase the symbolic value of local restaurants. To remain competitive, there is a need for domestic restaurants to manage and understand tourism ethnocentrism to leverage success.

Originality/value

This study contributes to the scarce domestic tourism literature. It contributes to understanding destination coolness in the context of domestic restaurants and increases the generalisability of the destination coolness scale. The study also adds to understanding the symbolic value in domestic gastronomy by examining social returns from peers. It also contributes to the limited research on tourism ethnocentrism by being the first to investigate tourism ethnocentrism in domestic travel and gastronomy experience. Overall, the cross-national nature of the study demonstrates the difference between decision-making behaviour between two distinct countries.
