Abstract

Purpose

Votage source converter (VSC) based or current source converter (CSC) based shunt active power filter (SAPF)? It is the main question in harmonic elimination project using SAPF.This paper presents some criteria based on which the designer can decide which type of filter is more suitable for implementation of the project according to the nature and characteristics of the project.

Design/methodology/approach

Owing to the importance of cost and power losses criteria, relevant equations will be formulated and comparative analysis will be carried out between conventional structures based on CSC or VSC. For validation of analyses, simulation results have been studied in the MATLAB–SIMULINK environment.

Findings

Simulation results have examined two important criteria of power losses and costs. Although the results show the superiority of VSSAPF to CSSAPF in both criteria, this comparison is performed in a general and conventional condition. Using third-order filters of inductive-capacitive-inductive (LCL) type in VSSAPF, using insulated-gate bipolar transistor (IGBT) with reverse-voltage blocking ability in CSSAPF, which eliminates the need to use series diodes, and the use of superconducting technology in the DC-side endpoint in CSSAPF, not only reduce the difference of cost and losses in two schemes but also may lead to the lower costs and losses in CSSAPF than VSSAPF.

Originality/value

This paper is the result of many years working on active power filter and can be useful for engineers who are engaged in industrial projects.

Abstract

Purpose

This paper aims to propose a “Four-F (finding facts, fostering alternates, fulfilling implementation and feasibility testing)” action plan to global food service businesses (FSB) such as restaurants (dine-in/take away) to build resilience during times of global crises. The 2019 Coronavirus disease and FSBs apply as working examples elaborating the proposed Four-F action plan with several managerial implications for the internal and external stakeholders of FSBs.

Design/methodology/approach

The method involves reviewing and coding 108 articles using the PRISMA approach, then applying findings to develop the Four-F action plan integrating multiple theoretical concepts (such as stakeholder, crisis management and dynamic capabilities).

Findings

There are two key findings. First, though all four crisis phases should be considered by decision-makers as part of their contingency planning process, the pre and post-crisis stages need higher attention. Second, the Four-F action plan provides specific recommendations to FSBs stakeholders (consumers, suppliers and government) for each crisis phase (pre-crisis, crisis emergence, crisis occurrence and post-crisis).

Originality/value

To the best of the authors’ knowledge, this is the first paper that has incorporated multiple theoretical frameworks (stakeholder theory, crisis management and dynamic capabilities) within the FSBs context and provided the Four-F action plan for decision-makers to understand and manage crisis phases.

Abstract

Purpose

This paper aims to understand the social dynamics surrounding the consumption of non-native, ethnic cuisines in the multicultural context of an Asian city.

Design/methodology/approach

Data were collected via in-depth interviews with 21 culturally diverse residents of Dubai. Data were analysed inductively, leading to the emergence of three themes characterising social dynamics underpinning the consumption of non-native cuisines in an Asian multicultural environment.

Findings

Three types of social dynamics were identified: instrumental uses, expressive uses and conviviality considerations.

Research limitations/implications

The study suggests that the different types of cultural dynamics at play have different roles; some act as influencing or constraining factors in the everyday practice of multicultural consumption, whereas others are used more proactively as enablers.

Originality/value

This paper contributes to the authors’ understanding of how people “practice conviviality” in multicultural marketplaces, providing insights into the complex social dynamics, underpinning the consumption of non-native cuisines in multicultural marketplaces. Although the consumer literature on food and cuisines has acknowledged the social influences surrounding cuisines and food consumption, these have typically been viewed in a single block. This study shows the importance of conviviality considerations in non-native cuisine consumption. Further, the paper shows that the consumption of non-native cuisines is an everyday practice in a multicultural context, which is used with varying degrees of proactiveness for social lubrication and multicultural socialisation.

Abstract

Purpose

This paper aims to examine adaptation in buyer–seller relationships in a time of crisis and to explore what consequences adaptation has for the actors involved. The authors are particularly interested in examining how suppliers and public buyers adapt in turbulent situations where public policy opens for interaction in a mode represented by studies in the industrial marketing and purchasing research approach. The COVID-19 pandemic represents such a unique research setting, as it opens up insights into how buyers and suppliers had to adapt in a matter of days in response to rapid and turbulent changes in their business environment. In this paper, the authors seek insights into the following research questions: What role do the actors’ interpretation of the situation play in the adaptation process? How do adaptation processes unfold in a time of national crisis? What are the actor and relationship-specific outcomes from adaptation in such a situation?

Design/methodology/approach

To answer these questions, the authors present data from an exploratory case study of intra- and interfirm adaptation processes between public buyers and private suppliers in the health-care sector during the COVID-19 pandemic. The pandemic opened for access to a unique data from personal interviews and secondary data, from public reports and newspaper/media coverage at intervals during the outbreak and at the aftermath of the pandemic.

Findings

The authors find that the actors’ interpretation of the situation and their motivation to engage in adaptations play an important role in the adaptation processes. In particular, a normative commitment based on a moral duty to contribute to dealing with the turbulent situation of society is found to be a main driver. In these situations, shared sensemaking and alignment of mental models help to mobilise actors, resources and activities into new interaction patterns. At the same time, mutual affective commitment between the buyer and suppliers is not significant over time, thus constraining and eventually terminating the adaptation processes.

Originality/value

This study contributes to the understanding of interaction between public buyers and suppliers during turbulent situations. Changes in the adaptation context opens for extensive interaction, thus enabling actors to combine and exploit resources of value, but temporary adaptations do not create long-term effects on the ability to develop buyer–supplier interaction in public markets.

Abstract

Purpose

The COVID-19 pandemic has led to major sales strategy and process changes as many interactions migrated from face-to-face to virtual environments. The nature of the interactions changed, and sales firms, the sales function and salespeople created new processes to excel in virtual environments. As sales processes evolve further, this paper aims to focus on understanding the enduring shifts in sales strategy and processes. In addition, this study seeks to understand the characteristics of enduring shifts and how they are distinct from temporary shifts.

Design/methodology/approach

This qualitative analysis provides a comprehensive overview of the sales organizations and salespeople over the period from the start of the pandemic to early 2022. The authors interviewed 66 sales professionals from different countries and industries to better understand the temporary and enduring shifts in sales strategy and processes, adopting ad inductive and narrative approach.

Findings

There are four major findings. First, four key themes emerged: increased digitalization, resistance to digitalization, sales process changes and sales organization transformation. Second, changes are classified as temporary, permanent and accelerated changes. Third, some proposed changes were not supported. Finally, five findings were found that were not discussed in previous literature.

Originality/value

This paper finds distinctive findings that offer additional valuable insights that connect to and extend existing literature. These include emerging themes, classification shifts, unsupported proposed changes and unique findings.

Abstract

Purpose

The Kingdom of Saudi Arabia’s dedicated pursuit of technological modernization positions it as a forefront leader in integrating advanced systems, aligning smoothly with the ambitious goals outlined in Vision 2030. The purpose of this study is to investigate the influence of integrating enterprise resource planning (ERP) and business intelligence (BI) systems on decision-making processes within the industrial sector of Saudi Arabia.

Design/methodology/approach

Using a quantitative research design, this study uses a bootstrapping approach and partial least squares structural equation modeling to meticulously analyze data collected from Saudi industrial firms.

Findings

The research reveals favorable relationships among infrastructure readiness, data quality, security and access control, user capabilities, user training and the integration of ERP and BI. These positive associations collectively affirm the overarching positive impact of ERP and BI integration on decision-making processes within the industrial sector.

Practical implications

The study underscores the strategic imperative of aligning organizational practices with the identified characteristics to fully unlock the potential benefits of ERP and BI integration in the Saudi Arabian industrial sector.

Originality/value

This study contributes significantly to the existing literature by delving into the integration of ERP and BI in the industrial sector and its nuanced impact on decision-making processes, specifically in the context of the Kingdom of Saudi Arabia – an area that has not been extensively studied.

Abstract

Purpose

The purpose of this paper is to establish the contextual factors that influence entrepreneurial intention to start the small and medium enterprises (SMEs) in Iran and to investigate why some manufacturing sector entrepreneurs achieve growth objectives while others do not.

Design/methodology/approach

In-depth semistructured interviews of 25 participants were used to investigate the contextual factors of entrepreneurship intention. On the basis of the data collected, a thematic content analysis has been carried out.

Findings

A set of contextual and cultural factors has been highlighted by the analysis. Data analysis led to the extraction of three main themes: external, internal and personal factors that were found to be significant determinants of entrepreneurship intention. In relation to the effect of these factors on their entrepreneurial behaviors, it emerged that there were the major barriers to entrepreneurial intentions including lack of resources, financial challenges and economic situation, which affected how they made strategic decisions about their plans. Moreover, the findings show that the key dimensions of organizational structure, public policies, social media, education and soft skills development are vital features and being influential in entrepreneurship.

Research limitations/implications

The study has industry-specific, size-specific and region-specific limitations. The qualitative research approach affects the generalizable character of the results.

Practical implications

The research findings have important implications for practicing entrepreneurs, start-ups and policymakers. The manuscript suggests a transition to a more collaborative approach from experts and practitioners in the field through policymakers to tackling the underlying determinants of entrepreneurship intention in Iran as a motive to economic growth. This research is significant since its findings should help regulators and investors better understand the opportunities and threats among manufacturing SMEs. This study implies a step forward in research into the entrepreneurship intention and SMEs literature, since the results differ from the evidence found for large companies in developing countries such as Iran. There is also a great contribution toward the debate regarding the need to consider the context and the type of firm in enterprise development studies.

Originality/value

This is the first empirical study conducted in Iran that explores three key elements of entrepreneurship intention interactively in Iran through qualitative research analysis. The research study fills a literature gap on the determinants of manufacturing SMEs’ functions. This manuscript explores the contextual factors that influence on entrepreneurial behavior in a conflict country context, using a thematic analysis for in-depth results. A new approach to evaluating entrepreneurial opportunities was used. The advantage of this empirical strategy is that it takes into account in more detail the content observations and experiences with the industry-specific insights. It also gives more description about the contingent nature of practice. Moreover, this qualitative research acknowledged the areas of conflict and contradiction around entrepreneurship phenomena among SMEs.

Abstract

Purpose

Marketing is all about understanding your consumers and giving them what they want. However, this process becomes more complicated in times of economic crisis and national slowdown. Consumers can become scattered and unpredictable in their behaviour, making it hard to understand what they want or need. At times like these, it is more important than ever to rely on qualitative market research to understand the views of consumers and managers. Thus, this study aims to look at the significant consumer challenges that arise during times of crisis and the marketing strategies that managers prefer to counter the crisis.

Design/methodology/approach

The data collected for this study involves an extensive literature review followed by personal interviews with industry experts. This study presents two separate models, indicating hierarchical relationships among consumer challenges during crisis and marketing strategies using the total interpretive structural modelling approach. Further MICMAC analysis (popularly known as cross-impact matrix multiplication) was also performed to assess each variable's driving and dependence power.

Findings

“Price sensitiveness” and “adaptive buying” result as driving factors with the highest driving and lowest dependence power, which further gives rise to other consumer behaviour challenges. Likewise, the most critical strategies are “information systems” and the formation of “crisis management teams” during a crisis. At the same time, other strategies have resulted as linkage and dependent factors and none as the autonomous factor.

Originality/value

This paper provides a systematic understanding of how a manager can understand the challenges consumers face during a crisis and suggests a powerful summary of strategies companies can implement to sail through a crisis.

Abstract

Purpose

The purpose of this study is to address the low localization accuracy and frequent tracking failures of traditional visual SLAM methods in low-light and weak-texture situations, and we propose a mobile robot visual-inertial localization method based on the improved point-line features VINS-mono algorithm.

Design/methodology/approach

First, the line feature information is introduced into VINS-mono. Subsequently, the EDlines line feature extraction algorithm is optimized with a short line merging strategy and a dynamic length suppression strategy to reduce redundant short lines and fragmented segments. In the back-end sliding window optimization, line feature reprojection errors are incorporated, and Huber kernel functions are added to the inertial measurement unit residuals, point-line feature residuals and loop closure constraints to reduce the impact of outliers on the optimization results.

Findings

Comparison and verification experiments are carried out on the EuRoC MAV Data set and real weakly textured environment. In the real low-light and weak-texture scenarios, the improved mobile robot localization system achieves over 40% higher accuracy compared to VINS-mono.

Originality/value

The main contribution of this study is to propose a new visual-inertial SLAM method combining point-line features, which can achieve good localization effect in low-light and weak-texture scenes, with higher accuracy and robustness.

Abstract

Purpose

This study investigates to what extent strategic flexibility of international strategic alliances (ISAs) affects export performance of emerging market small and medium-sized enterprises (ESMEs) via international marketing capability in crises. It also examines whether these ESMEs’ adoption of digital technology strengthens the impact of strategic flexibility of ISAs on international marketing capability.

Design/methodology/approach

Based on the international alliance and dynamic capability perspectives on strategic flexibility, the authors develop a conceptual model and empirically examine the mediation and moderation effects between strategic flexibility of ISAs, international marketing capability, export performance and adoption of digital technology. The authors collected survey data from 129 ESMEs located in Pakistan between May 2021 and August 2021 and tested the conceptual model with hierarchical-moderated regression analysis.

Findings

The findings suggest that strategic flexibility of ISAs positively impacts on export performance of ESMEs in crises. Moreover, the authors found that international marketing significantly mediates the relationship between strategic flexibility of ISAs and export performance of ESMEs. Also, the adoption of digital technologies significantly moderates the relationship between strategic flexibility of ISAs positively and international marketing capability.

Originality/value

The authors take strategic flexibility of ISAs in the context of the emerging market and how ESMEs enhance export performance in a time of crisis, which extends the prior ESMEs’ international marketing strategy and crisis management literature. In particular, the authors show that strategic flexibility of ISAs is a vital dynamic capability to enhance export performance of ESMEs via international marketing capability and adoption of digital technologies.
