Abstract

Purpose

The purpose of optimal protocol prediction and the benefits offered by quantum key distribution (QKD), including unbreakable security, there is a growing interest in the practical realization of quantum communication. Realization of the optimal protocol predictor in quantum key distribution is a critical step toward commercialization of QKD.

Design/methodology/approach

The proposed work designs a machine learning model such as K-nearest neighbor algorithm, convolutional neural networks, decision tree (DT), support vector machine and random forest (RF) for optimal protocol selector for quantum key distribution network (QKDN).

Findings

Because of the effectiveness of machine learning methods in predicting effective solutions using data, these models will be the best optimal protocol selectors for achieving high efficiency for QKDN. The results show that the best machine learning method for predicting optimal protocol in QKD is the RF algorithm. It also validates the effectiveness of machine learning in optimal protocol selection.

Originality/value

The proposed work was done using algorithms like the local search algorithm or exhaustive traversal, however the major downside of using these algorithms is that it takes a very long time to revert back results, which is unacceptable for commercial systems. Hence, machine learning methods are proposed to see the effectiveness of prediction for achieving high efficiency.

Abstract

Purpose

The purpose of this research is to investigate the role of social media in supporting the psychological well-being of young expatriates.

Design/methodology/approach

The study adopts a qualitative research design based on semi-structured interviews with Gen Z expatriates who are active social media users.

Findings

This study reveals social media’s pivotal role in enhancing Gen Z expatriates’ psychological well-being. It fosters virtual connections to their home country, validating their distinctive international experiences, facilitating integration into the host culture and challenging stereotypes. By developing bonding and bridging social capital, social media mitigates cultural distance, strengthens social support and ultimately contributes to positive expatriate well-being.

Originality/value

This research responds to the growing call for studies on the intersection of digitalization and expatriation, offering insights into how digital tools can enhance the well-being of expatriates. By developing a conceptual model grounded in social media and expatriate support literature, this research highlights the specific mechanisms through which social media impacts the psychological well-being of Gen Z expatriates, a previously under-researched area. While physical support is limited by geographical proximity and shared experiences, digital support can transcend these boundaries, providing access to a wider range of resources and perspectives. By focusing on Gen Z, a generation known for its digital fluency and reliance on social media, we provide insights that can inform targeted interventions and support strategies specifically tailored to this demographic.

Abstract

Purpose

Despite being one of the most used dependent variables in expatriate management research, no clear-cut understanding exists of what expatriate success means. Thus, this study aims to propose an integrative definition of expatriate success by providing an overview of expatriate success's dimensions, antecedents, and their interplay.

Design/methodology/approach

A systematic literature review (SLR) was conducted to achieve the purpose. A total of 249 empirical studies (quantitative 111, qualitative 50, mixed-methods 17), literature reviews (67) and meta-analyses (4) on expatriate success were reviewed from Web of Science and Scopus databases published from 1990 until December 2021. The study selection criteria followed the PRISMA flowchart steps, and then descriptive and network analyses were performed to identify expatriates' success dimensions, antecedents and their interplay.

Findings

The findings show the interplay among antecedents and dimensions of expatriate success across three levels (individual, interpersonal and organisational) to clarify the concept of expatriate success. Also, the study offers a comprehensive definition of expatriate success based on the dimensions identified.

Research limitations/implications

The suggested definition of expatriate success elucidates the “atheoretical”, multidimensional and socially constructed nature of the construct and hence, calls for more “theoretical”, multidimensional and subjective considerations of the term to ground human resource management practices addressed to attain expatriates' success.

Originality/value

This paper provides an integrative definition of expatriate success, giving greater insight into the construct, in addition to critically reflecting on it.

Abstract

Neons Fashion LLP was an entrepreneurial venture of Arthi Ramalingam after completion of her MBA. Arthi had an interest in jewellery since childhood and she decided to focus on design, manufacturing and retailing of fashion and costume jewellery items under the brand name of Eternz through different sales channels like exhibitions, retail stores, own website and as an independent seller on e-commerce marketplaces. She initially started selling on Amazon marketplace through a third party, Cloudtail India Pvt. Ltd., and later sold through other e-commerce marketplace operators like Flipkart, Jabong and FirstCry. As her business grew, Arthi planned to add the kids' shoes category and also decided to participate in Bangalore Fashion Week to build the Eternz brand. However, in November 2016, Cloudtail terminated her contract which played havoc with the sales and profitability of her start-up. Neons Fashion LLP (A) provides details of how independent sellers are at the mercy of marketplace operators and ends with the need to review the choices of sales channels for different categories like fashion garments and fashion accessories, and for the upcoming launch of kids' shoes. Neons Fashion LLP (B) describes the events after the Bangalore Fashion Week that ultimately led to closure of business.

Abstract

Purpose

The purpose of this study is twofold. First, to consider the ways in which transportation could be more sustainable in North Cyprus, which is mostly dependent on tourism and higher education as a small island destination. Second, to investigate current issues in the transportation sector related to the impact of the COVID-19 pandemic.

Design/methodology/approach

This study employed a qualitative approach, and a descriptive analysis technique was used to analyse semi-structured interviews, conducted by telephone and face-to-face. To investigate current problems in the North Cyprus transportation sector – one of the most affected by the pandemic – travel agencies were chosen as the study’s population and research participants were selected purposively.

Findings

The findings indicate that the unpredictability of domestic policies combined with the structural challenges confronting North Cyprus contribute to unsustainable current transportation policies. North Cyprus transport and tourism both suffered significant losses during the pandemic but travel agencies were disproportionately impacted. Our study results showed that exorbitant ticket prices, taxes and transportation costs have emerged as the most significant issues in the transportation sector.

Research limitations/implications

More efficient and accurate policies that meet the needs of the sector and give opportunity for development are required. This is a critical issue for policymakers to address, as they also represent a significant barrier to the sector's long-term competitiveness.

Originality/value

To the best of the authors' knowledge, this is the first qualitative study to look at North Cyprus’ transportation problems from the perspective of travel agencies and the impact of the pandemic. It is thought that this study will contribute to the development of solutions for transportation problems and sustainable practices in small island developing states.

Abstract

Informal associations are typical features of farm and non-farm ventures especially within rural communities. Owing to the informality of these associations, members of the groups usually evolve strategies to cope with different kinds of economic and social shocks such as the COVID-19 pandemic or unexpected economic recessions. Accordingly, entrepreneurship and non-farm business development in rural areas require massive finance input, which this group largely lacks owing to agrarian activities which is the main source of revenue. Therefore, to inform rural development policies, this chapter draws on the interrelationships that exist between finance options (including formal, informal and social networks) and small business development. Using the World Bank Living Standards Measurement Survey – Integrated Surveys on Agriculture (LSMS-ISA), the analytics identifies informal financing and social networks as leading alternatives to formal financing option in rural businesses. Therefore, we suggest that the government institutions recognise and formalise informal finance systems. This will not only aid access to government interventions and programmes, but foster collaborations with existing formal institutions and investors for sustainable rural business financing.

Abstract

Purpose: This chapter aims to illuminate the cultural perceptions of illicit alcohol and to examine the role of cognitive polyphasia in changing the perceptions and legitimacy of market practices.

Methodology/Approach: An ethnographic study of the Kenyan illicit alcohol market, which combined digital news media data analysis, with observation and interview data.

Findings: Cognitive polyphasia serves to delegitimize illicit alcohol by portraying it as incongruent with existing cultural beliefs, values, and assumptions. Illicit alcohol is portrayed as a contaminated product, a cursed business, a practice that causes cultural breech, and a scheme of witchcraft/sorcery used to enslave consumers. Findings also show that cognitive polyphasia involves drawing on traditional knowledge to explain misfortune and difficult social phenomena such as addiction. The delegitimation of illicit alcohol induces behavior and perception change. Consumers play an important role in this change process.

Research Implications: This research proposes the incorporation of cultural language into alcohol policy and education.

Social Implications: By illuminating social representations in the cultural-cognitive arena, a theory for applying these factors to change markets/behavior is proposed.

Originality/Value of Paper: The chapter highlights the delegitimation of market practices, unlike previous research that focuses on legitimation processes. This chapter also demonstrates how cognitive polyphasia, a scarcely researched concept in consumer research, can induce behavior change. This chapter also contributes to the literature on market/behavior change by revealing potential cultural-cognitive barriers to change.

Abstract

Purpose

This study aims to reveal whether green perceived organizational support has a mediating role in the relationship between managers’ green transformational leadership and the green self-efficacy beliefs of employees.

Design/methodology/approach

The textile industry is a sector with fast and cheap production and is the second most damaging sector to the environment due to excessive consumption and rapidly changing fashion trends. Hence, textile industry employees were selected as the research object. The data were collected by survey method from 274 people working in businesses operating in the textile sector in Türkiye. The collected data were analyzed in the SmartPLS 4 analysis program.

Findings

The analysis found that managers’ green transformational leadership increases employees’ green self-efficacy beliefs. Likewise, it was determined that managers’ green transformational leadership increases employees’ green perceived organizational support. The analysis also indicated that employees’ green perceived organizational support increases employees’ green self-efficacy beliefs. Finally, as a result of the analysis, it was concluded that green perceived organizational support is a complementary partial mediator variable in the relationship between managers’ green transformational leadership and employees’ green self-efficacy beliefs.

Originality/value

The available literature has overlooked the mediating role of green perceived organizational support in the relationship between managers’ green transformational leadership and the green self-efficacy beliefs of employees. This work makes new contributions to the literature and practice by revealing the significance of managers’ green transformational leadership and green perceived organizational support in increasing employees’ green self-efficacy beliefs.

Abstract

Purpose

The purpose of this paper is to propose a conceptual structural equation model to investigate the relationships among self‐directed learning (SDL), organizational learning (OL), knowledge management capability (KMC) and organizational performance (OP) and to demonstrate the direct and indirect effect of SDL on OP from the perspectives of KMC and OL.

Design/methodology/approach

An empirical study is conducted in 21 technological companies (N=236) in Taiwan and the collected survey data are used to test the relationships among the four dimensions expressed in the proposed structural equation model.

Findings

The results show that SDL has a direct and significant impact on OL and KMC. SDL influences OP indirectly through OL and KMC. In addition, OL and KMC have direct and significant influences on OP.

Research limitations/implications

The source of data collected is Taiwan, hence, the results may not be easily generalized to other areas or countries. However, the findings are valuable for managers' reference, especially for those whose circumstances are similar to those in Taiwan.

Practical implications

The conceptual structural equation model provides useful information for managers to enhance OP through the adoption of appropriate SDL, OL and KMC strategies.

Originality/value

The study demonstrates how SDL indirectly impacts OP and illustrates the paths of influence through either OL or KMC.
