Abstract
Purpose
A number of works have been published in the scientific literature proposing the solution of heat diffusion problems by first transforming the relevant partial differential equation to the frequency domain. The purpose of this paper is to present a mesh-free strategy to assess transient heat propagation in the frequency domain, also allowing incorporating initial non-zero conditions.
Design/methodology/approach
The strategy followed here is based in Kansa's method, using the MQ RBF as a basis function. The resulting method is truly mesh-free, and does not require any domain or boundary integrals to be evaluated. The definition of good values for the free parameter of the MQ RBF is also addressed.
Findings
The strategy was found to be accurate in the calculation of both frequency and time-domain responses. The time evolution of the temperature considering an initial non-uniform distribution of temperatures compared well with a standard time-marching algorithm, based on an implicit Crank-Nicholson implementation. It was possible to calculate frequency-dependent values for the free parameter of the radial basis function.
Originality/value
As far as the authors are aware, previous implementations of the frequency domain heat transfer approach required domain integrals to be evaluated in order to implement non-zero initial conditions. This is totally avoided with the present formulation. Additionally, the method is truly mesh-free, accurate and does not require any element or background mesh to be defined.

This study aims to highlight the system-wide potential relationships between forms of human bias, selected Lean tools and types of waste in a manufacturing process.
Abstract
Purpose
This study aims to highlight the system-wide potential relationships between forms of human bias, selected Lean tools and types of waste in a manufacturing process.
Design/methodology/approach
A longitudinal single-site ethnographic case study using digital processing to make a material receiving process Lean was adopted. An inherent knowledge process with internal stakeholders in a stimulated situation alongside process requirements was performed to achieve quality data collection. The results of the narrative analysis and process observation, combined with a literature review identified widely used Lean tools, wastes and biases that produced a model for the relationships.
Findings
The study established the relationships between bias, Lean tools and wastes which enabled 97.6% error reduction, improved on-time accounting and eliminated three working hours per day. These savings resulted in seven employees being redeployed to new areas with delivery time for products reduced by seven days.
Research limitations/implications
The single site case study with a supporting literature survey underpinning the model would benefit from testing the model in application to different industries and locations.
Practical implications
Application of the model can identify potential relationships between a group of human biases, 25 Lean tools and 10 types of wastes in Lean manufacturing processes that support decision makers and line managers in productivity improvement. The model can be used to identify potential relationships between forms of human biases, Lean tools and types of wastes in Lean manufacturing processes and take suitable remedial actions. The influence of biases and the model could be used as a basis to counter implementation barriers and reduce system-wide wastes.
Originality/value
To the best of the authors’ knowledge, this is the first study that connects the cognitive perspectives of Lean business processes with waste production and human biases. As part of the process, a relationship model is derived.

Abstract
Purpose
The purpose of this paper is to explore the adoption of lean practices by manufacturing companies in regions of low economic and technological development and to compare findings with previous studies from more developed regions highlighting important contextual differences. The paper uses the contingency theory to explore how contextual variables and scarce resources influence the adoption of lean practices.
Design/methodology/approach
A survey of 233 manufacturing firms was conducted in the State of Pará in the Amazon Region of Brazil.
Findings
The results demonstrate that six internal lean practices (single minute exchange of dies, human resource management, continuous flow, total productive maintenance, pull and statistical process control) and two external lean practices (supplier feedback and customer involvement) are implemented. However, the two external lean practices of just-in-time delivery by suppliers and supplier development were not implemented. Furthermore, from the 36 operating items comprised in eight lean practices that are being used, 13 were not implemented. As such, compared to developed regions, there is evidence for a more fragmented implementation in less developed regions. The results reveal empirical evidence explained by the contingency perspective, such as national, geographical, strategic context and culture.
Originality/value
There is broad evidence on lean implementation in developed and developing countries in the literature. However, little is known about lean implementation in poorer regions of developing counties. This is one of the first studies mapping lean implementation in a region with low economic and technological development. This has important implications for research and practice, especially to cross-country/cultural research on operation management.

Abstract
Purpose
Using the resource-based view (RBV), our study aims to provide theoretical and empirical insights into blockchain capabilities’ (BCs) compounded and sequential effects on supply chain competitive advantages (CA).
Design/methodology/approach
We combined a systematic literature review and an expert interview. Interpretive Structural Modelling and a Matrix of Cross-Impact Multiplications Applied to Classification were used to determine the relationship between the capabilities. Simple Additive Weighting assessed each capability’s relative importance and impact.
Findings
We reveal a sequential development path for BCs. Foundational capabilities, such as cybersecurity, provide immediate performance benefits, establishing a unique, valuable and inimitable resource. As firms progress to advanced capabilities, the compounded value of these capabilities generates a stronger, dynamic resource for sustained CA. Moreover, the study underscores the strategic importance of timing in adopting and developing BCs, as early adoption can secure a competitive edge difficult for later entrants to replicate.
Practical implications
Our proposed framework guides managers in incorporating blockchain technology into supply chain management (SCM) processes once it demonstrates that firms can enhance their CA by prioritizing the technical basics BC, leveraging the informational capabilities in level two and enabling effective problem-solving through level three. Our framework also shows that a learning process occurs as BCs are used and their results are explored.
Originality/value
Our study extends the RBV by demonstrating BCs’ cumulative and interdependent nature in SCM. It emphasizes the synergistic interactions between these capabilities, which collectively enhance CA.

Abstract
Purpose
The integration of blockchain technology (BT) in supply chain management (SCM) is at the forefront of technological advancements, yet it faces significant barriers that hinder its widespread adoption. This study aims to delve into these challenges, employing the diffusion of innovations (DOI) theory to systematically investigate and propose a strategic framework for overcoming the technological barriers to BT adoption within SCM.
Design/methodology/approach
Through a comprehensive systematic literature review (SLR) of 155 publications, complemented by rigorous content analysis and expert interviews, this research identifies and categorizes 16 primary technological barriers, including scalability and privacy issues, that impede BT integration.
Findings
The proposed framework, informed by DOI theory, outlines tailored strategies across three critical adoption stages: initiation, where the focus is on mitigating high energy consumption and scalability issues; adoption decision, emphasizing the formulating international standards for blockchain architecture, embedding abstraction layers within software projects; and implementation, concentrating on enhancing security, interoperability and system efficiency.
Originality/value
This research contributes significantly to both academic literature and practical applications. Academically, it extends the DOI theory within the SCM context and enriches the blockchain literature by providing a nuanced understanding of the specific barriers to BT adoption. Practically, it offers a roadmap for industry practitioners, delineating actionable strategies to navigate the adoption process effectively. This study not only bridges the gap between theoretical insights and practical implementations but also serves as a vital resource for policymakers and standard-setting bodies in facilitating and regulating BT adoption in SCM, thereby fostering innovation and competitive advantage in the marketplace.

Abstract
Purpose
This paper aims to explore the external factors that lead Western firms to fail in the Chinese market, proposing to reveal the main challenges they face in this market, such as culture, guanxi or others. Based on network theory, the authors propose to group failure attributes and actions to predict business failure.
Design/methodology/approach
Qualitative research based on in-depth interviews is conducted, with a sample of 21 individuals, from former/current managers that did or are currently doing business in China and a person from the Chinese Government. This research resorts to inductive reasoning and to Atlas.ti software to perform the analysis.
Findings
The findings reveal that it is possible to cluster seven distinct categories of external factors. Additionally, Chinese culture, local partnerships and the “catching-up effect” by Chinese firms are also external factors to be considered. The role of guanxi in China is changing, taking another format, and international companies in the Chinese market must take this into account.
Research limitations/implications
Several limitations arise in this research, such as information availability and time constraints, sample size and the characteristics of Chinese society (i.e. type of government). This study also proposes further confirmatory research to test the seven clusters proposed.
Practical implications
Managers can understand patterns of business failures when targeting the Chinese market and use the seven clusters as a tool to address this market appropriately in the future.
Originality/value
This paper intends to shed light on Western firms’ business failure in the Chinese market. The authors argue that several external factors linked to network surroundings contribute to Western firms failing in this market and that network failure attribution is still an understudied topic.

Abstract
Purpose
The purpose of this paper is to offer a comprehensive overview of current research on customer behavior in the business-to-business (B2B) context and propose a research agenda for future studies. Despite being a relatively recent area of interest for academics and practitioners, a literature review that synthesizes existing knowledge into coherent topics and outlines a research agenda for future research is still lacking.
Design/methodology/approach
Drawing on a systematic literature review of 219 papers and using a text-mining approach based on the Latent Dirichlet Allocation algorithm, this paper enhances the existing knowledge of B2B customer behavior and provides a descriptive analysis of the literature.
Findings
From this review, ten major research topics are found and analyzed. These topics were analyzed through the lens of the Theory, Context, Characteristics and Method framework, providing a summary of key findings from prior studies. Additionally, an integrative framework was developed, offering insights into future research directions.
Originality/value
This study presents a novel contribution to the field of B2B by providing a systematic review of the topic of customer behavior, filling a gap in the literature and offering a valuable resource for scholars and managers seeking to advance the field.

Abstract
Purpose
The purpose of this study is to assess the state at which lean and six sigma (LSS) are used as a management system to improve the national health system national health system of Mexico.
Design/methodology/approach
Cross-sectional survey-research. The survey was administered at 30 different hospitals across six states in Mexico. These were selected using convenience sampling and participants (N = 258) were selected through random/snowball sampling procedures, including from top managers down to front-line staff.
Findings
Only 16 per cent of respondents reported participation in LSS projects. Still, these implementations are limited to using isolated tools, mainly 5s, failure mode and effects analysis (FMEA) and Fishbone diagram, with the lack of training/knowledge and financial resources as the top disabling factors. Overall, LSS has not become systematic in daily management and operations.
Research limitations/implications
The sampling procedure was by convenience; however, every attempt was made to ensure a lack of bias in the individual responses. If still there was a bias, it is conjectured that this would likely be in overestimating the penetration of LSS.
Practical implications
The penetration of LSS management practices into the Mexican health system is in its infancy, and the sustainability of current projects is jeopardized given the lack of systematic integration. Hence, LSS should be better spread and communicated across healthcare organizations in Mexico.
Originality/value
This is the first research work that evaluates the use of LSS management practices in a Latin American country, and the first journal paper that focuses on LSS in healthcare in Mexico.

The aim of this study is to identify and analyse the main strategic differences between fast and ultra-fast fashion supply chain management.
Abstract
Purpose
The aim of this study is to identify and analyse the main strategic differences between fast and ultra-fast fashion supply chain management.
Design/methodology/approach
This study uses a qualitative approach, using document analysis and in-depth interviews with industry specialists.
Findings
Ultra-fast fashion differs from fast in the following supply chain strategies: avoids any excess inventory, focuses on local manufacturing, on-demand production, and shorter lead times from a few days to a week with a combination of agile, lean, responsive supply chain strategies.
Research limitations/implications
The limitations of this research are due to the cut-off period and the use of a restricted sample. As implications, technological capabilities are underexplored in the fashion industry. Although important to the traditional and fast fashion industry, technology is viewed as a tool and not as a capability that can generate competitive advantage. This paper addresses technology as capabilities to make ultra-fast fashion retailers more competitive.
Practical implications
Ultra-fast fashion could potentially impact current fast fashion retailers to partially move their business model and operations towards an ultra-fast approach. Fast fashion retailers desiring to speed up their production processes launch more weekly collections to cater to consumers who are more fashion-conscious.
Originality/value
There is a rapid emergence of new start-ups that are calling themselves ultra-fast. Newcomers wanting to adopt this new segment’s business model, develop technological capabilities to meet the challenges of this supercompetitive market.

Abstract
Purpose
The Macau Special Administrative Region (MSAR) of the People’s Republic of China (PRC) has a unique identity. This study is based on a long period of research undertaken between 1995 and 2014. Permanent residents, the Chinese of Macau and all other MSAR residents constitute a body of model “citizens” which makes their legal identity understandable in the MSAR’s present social and economic context. Macau’s legal identity is based on centuries of trade and commerce. In Article 5 of the first chapter (I-5) of the MSAR’s Basic Law, the “way of life” in Macau’s society and economy are recognized as part of the MSAR’s legal framework. However, social change may play an important role in Macau’s development. The purpose of this paper is to look at the legal corpus as though it was a physical body with rights and duties, but also capabilities based on the nationality and residence statuses of its citizens, its companies and other entities (which will be studied more specifically in following articles).
Design/methodology/approach
This study has used the combined approaches of fieldwork carried out between 2010 and 2015, interviews, and questionnaires.
Findings
Way of life and the concept of One Country, Two Systems are key points that contribute to Macau’s contemporary identity. Way of life in the Basic Law constitutes a complex matrix formulation based on a series of particular facts and cultural traits, which leads to a better legal definition of important concepts such as nationality and residency in the particular case of Macau. The Basic Law is the constitutional law of the MSAR, but “Chineseness” still dominates the locals’ identity from day to day. More than 65 percent of the interviewees in the survey asserted their “Chineseness.” However, both Chinese and Portuguese, will continue to be official languages of Macau until 2049. The MSAR’s Chinese society speaks Cantonese and increasingly Putonghua, but it does not seem concerned by communicating using the Portuguese language. Clayton’s thesis emphasized the “unique cultural identity” of the MSAR and wrote that what made the Chinese of Macau “different from other Chinese, is the existence of a Portuguese state on Chinese soil.” Portuguese cultural tolerance is not mentioned, but it is a historical fact that has influenced Macau’s legal identity. The MSAR’s government has done its best to harmonize Macau’s multicultural society and it has particularly protected the Sino-Portuguese way of life in Macau.
Practical implications
To apply the law and maintain the existing harmony in its society and economy, legal actions have had to be taken by the Macau government and courts. The courts of the MSAR are structured in three levels and have final powers of adjudication, except in very narrow political areas. The judicial system includes the following courts, from the highest to the lowest: the Court of Final Appeal, the Court of Second Instance and the Court of First Instance (Tribunal de Primeira Instância).
Originality/value
This research is unique inasmuch as studies of legal identities focussed on large regions such as the MSAR of China are rare.
