Abstract
Purpose
To investigate the influence of vehicle operation speed, curve geometry parameters and rail profile parameters on wheel–rail creepage in high-speed railway curves and propose a multi-parameter coordinated optimization strategy to reduce wheel–rail contact fatigue damage.
Design/methodology/approach
Taking a small-radius curve of a high-speed railway as the research object, field measurements were conducted to obtain track parameters and wheel–rail profiles. A coupled vehicle-track dynamics model was established. Multiple numerical experiments were designed using the Latin Hypercube Sampling method to extract wheel-rail creepage indicators and construct a parameter-creepage response surface model.
Findings
Key service parameters affecting wheel–rail creepage were identified, including the matching relationship between curve geometry and vehicle speed and rail profile parameters. The influence patterns of various parameters on wheel–rail creepage were revealed through response surface analysis, leading to the establishment of parameter optimization criteria.
Originality/value
This study presents the systematic investigation of wheel–rail creepage characteristics under multi-parameter coupling in high-speed railway curves. A response surface-based parameter-creepage relationship model was established, and a multi-parameter coordinated optimization strategy was proposed. The research findings provide theoretical guidance for controlling wheel–rail contact fatigue damage and optimizing wheel–rail profiles in high-speed railway curves.

Abstract
Purpose
The integration of industry 4.0 has become a priority for many organizations. However, not all organizations are suitable and capable of implementing industry 4.0 because it requires a dynamic and flexible implementation strategy. The implementation of industry 4.0 often involves overcoming several tensions between internal and external stakeholders. This paper aims to explore the paradoxical tensions that arise for health-care organizations when integrating industry 4.0. Moreover, it discusses how a paradox lens can support the conceptualization and proposes techniques for handling tensions during the integration of industry 4.0.
Design/methodology/approach
This qualitative and in-depth study draws upon 32 semi-structured interviews. The empirical case concerns how two health-care organizations handle paradoxical tensions during the integration of industry 4.0.
Findings
The exploration resulted in six recurring technology tensions: technology invention (modularized design vs. flexible design), technology collaboration (automation vs. human augmentation), technology-driven patient experience (control vs. autonomy), technology uncertainty (short-term experimentation vs. long-term planning), technology invention and diffusion through collaborative efforts among stakeholders (selective vs. intensive collaboration) and technological innovation (market maintenance vs. disruption).
Originality/value
A paradox theory-informed conceptual model is proposed for how to handle tensions during the integration of industry 4.0. To the best of the authors’ knowledge, this is the first paper to introduce paradox theory for quality management, including lean and Six Sigma.

Abstract
Purpose
Contradictory sustainability priorities and perspectives among supply chain actors in greening transportation can be challenging. Several of these contradictions can be described as paradoxes (i.e. interests that are logical in themselves, but become irrational when perceived together). The aim of this study is to increase the understanding of paradoxical tensions hampering the greening of transportation in transport buyer–supplier dyads.
Design/methodology/approach
A case study method targeting greening transportation in two transport buyer–supplier dyads was applied, followed by an analysis with a point-of-departure in paradox theory.
Findings
Tensions related to performing, belonging, learning and organizing paradoxes in greening transportation were identified. These tensions arise as a consequence of actions, perspectives and other tensions, within three identified loci in individual companies and in dyads.
Research limitations/implications
By identifying examples of tensions through the lens of paradoxes in a particular setting, this study provides an increased understanding of why the transition toward green transportation goes slow, despite the high ambitions of involved actors. The suggested framework provides a novel contribution to the literature that further increases the understanding of tensions, by providing additional insights into where tensions arise and how actions, perspectives and tensions in one place of a locus spectrum can disseminate along that spectrum.
Originality/value
This study is original because it applies paradox theory and the four categories of performing, belonging, learning and organizing within the field of greening transportation, and in particular as a lens to study interactions between different actors.

Abstract
Purpose
Grounded in paradox theory, and with the objective of structuring and extending existing knowledge of conflicts of interest (e.g. trade-offs) in packaging logistics, the purpose of this paper is to identify categories of paradoxical tensions in packaging systems used in supply chains, and to develop a conceptual framework that describes these categories.
Design/methodology/approach
This research uses a theory building approach. It develops a conceptual framework of paradoxical tensions for packed products in supply chains. It revises and extends current knowledge in this domain by applying paradox theory from organisational research.
Findings
The paper develops a generic, conceptual framework that identifies, categorises and describes packed product paradoxes on two system levels: supply chain and company levels. The categories of paradoxes refer to performing, organising, belonging and learning.
Research limitations/implications
The framework provides a new theoretical explanation of conflicts of interest in packaging logistics in terms of paradoxical tensions related to packed products in supply chains. It structures and increases general understanding of such tensions within and between actors in a supply chain. The paper also discusses differences in terminology between tensions which are possible to settle and those which lead to paradoxes.
Practical implications
The framework provides a structure for analysing the organisational impact of strategic packaging decisions. It can help highlight different stakeholders' organisational constraints related to packaging.
Originality/value
The framework's systematic categorisation of four types of paradoxical tensions, with thorough descriptions of the meaning of packed product paradoxes of each type, offers an expanded and in-depth explanation of the organisational impacts of packed products in supply chains.

Abstract
Purpose
The aim of this paper is to present the first diffusion analysis of ISO/IEC 27001, the fourth most popular ISO certification at global level and the most important standard for information security.
Design/methodology/approach
To achieve the purposes, the authors applied Grey Models (GM) – Even GM (1,1), Even GM (1,1,α,θ), Discrete GM (1,1), Discrete GM (1,1,α) – complemented by the relative growth rate and the doubling time indexes on the six most important countries in terms of issued certificates.
Findings
Results show that a growing trend is likely to be expected in the years to come and that China will lead at country level.
Originality/value
The study contributes to the scientific debate by presenting the first diffusive analysis of ISO/IEC 27001 and by proposing a forecasting approach that to date has found little application in the field of international standards.

Abstract
Social relationships play an important role in organizational entrepreneurship. They are crucial to entrepreneurs’ decisions because, despite the bleeding-edge technological advancements observed nowadays, entrepreneurs as human beings will always strive to be social. During the COVID-19 pandemic many companies moved activities into the virtual world and as a result offline Social relationships became rarer, but as it turns out, even more valuable, likewise, the inter-organizational cooperation enabling many companies to survive.
This chapter aims to develop knowledge about entrepreneurs’ SR and their links with inter-organizational cooperation. The results of an integrative systematic literature review show that the concept of Social relationships, although often investigated, lacks a clear definition, conceptualization, and operationalization. This chapter revealed a great diversity of definitions for Social relationships, including different scopes of meaning and levels of analysis. The authors identify 10 building blocks and nine sources of entrepreneurs’ Social relationships. The authors offer an original typology of Social relationships using 12 criteria. Interestingly, with regard to building blocks, besides those frequently considered such as trust, reciprocity and commitment, the authors also point to others more rarely and narrowly discussed, such as gratitude, satisfaction and affection. Similarly, the authors discuss the varied scope of sources, including workplace, family/friendship, past relationships, and ethnic or religious bonds. The findings of this study point to a variety of links between Social relationships and inter-organizational cooperation, including their positive and negative influences on one another. These links appear to be extremely dynamic, bi-directional and highly complex.

Abstract
Purpose
As social networks have developed to be a ubiquitous platform of public opinion spreading, it becomes more and more crucial for maintaining social security and stability by accurately predicting various trends of public opinion dissemination in social networks. Considering the fact that the dissemination of online public opinion is a dynamic process full of uncertainty and complexity, this study establishes a novel conformable fractional discrete grey model with linear time-varying parameters, namely the CFTDGM(1,1) model, for more accurate prediction of online public opinion trends.
Design/methodology/approach
First, the conformable fractional accumulation and difference operators are employed to build the CFTDGM(1,1) model for enhancing the traditional integer-order discrete grey model with linear time-varying parameters. Then, to improve forecasting accuracy, a base value correction term is introduced to optimize the iterative base value of the CFTDGM(1,1) model. Next, the differential evolution algorithm is selected to determine the optimal order of the proposed model through a comparison with the whale optimization algorithm and the particle swarm optimization algorithm. The least squares method is utilized to estimate the parameter values of the CFTDGM(1,1) model. In addition, the effectiveness of the CFTDGM(1,1) model is tested through a public opinion event about “IG team winning the championship”. Finally, we conduct empirical analysis on two hot online public opinion events regarding “Chengdu toddler mauled by Rottweiler” and “Mayday band suspected of lip-syncing,” to further assess the prediction ability and applicability of the CFTDGM(1,1) model by comparison with seven other existing grey models.
Findings
The test case and empirical analysis on two recent hot events reveal that the CFTDGM(1,1) model outperforms most of the existing grey models in terms of prediction performance. Therefore, the CFTDGM(1,1) model is chosen to forecast the development trends of these two hot events. The prediction results indicate that public attention to both events will decline slowly over the next three days.
Originality/value
A conformable fractional discrete grey model is proposed with the help of conformable fractional operators and a base value correction term to improve the traditional discrete grey model. The test case and empirical analysis on two recent hot events indicate that this novel model has higher accuracy and feasibility in online public opinion trend prediction.

Abstract
Purpose
This study investigates the impact of chief executive officers (CEOs’) and board members’ personal characteristics on their firms’ environmental, social and governance (ESG) performance.
Design/methodology/approach
Using a sample of 120,834 firm-year observations, this study used fixed-effect ordinary least squares regression analysis to empirically identify which characteristics of the CEO and board members are linked to ESG performance.
Findings
The results from analyzing archival data of privately held Finnish firms show that education level positively influences ESG performance, while age and income negatively affect total ESG performance.
Research limitations/implications
The findings highlight the importance of these characteristics in promoting ESG practices in private firms. Therefore, it will enable regulators to encourage diversity among the board members and the CEO, thereby helping to identify potential areas for improvement in corporate governance and leadership practices. The results also provide insights into how organizations can better align their actions with their values and goals.
Originality/value
This study adds to existing literature on corporate governance and ESG performance by identifying the specific personal characteristics of the directors, such as previous conviction, age, income and marital status, and their influences on ESG performance in privately held firms in Finland.

Abstract
Developing leaders for a diverse democracy is an increasingly important aim of higher education and social justice is ever more a goal of leadership education efforts. Accordingly, it is important to explore how dominant leadership models, as blueprints for student leadership development, account for and may unwittingly reinforce systems of domination, like racism. This critical discourse analysis, rooted in racialization and color-evasiveness, examines three prominent college student leadership development models to examine how leaders and leadership are racialized. We find that all three leadership texts frame leaders and leadership in color-evasive ways. Specifically, the texts’ discourses reveal three mechanisms for evading race in leadership: focusing on individual identities, emphasizing universality, and centering collaboration. Implications for race in leadership development, the social construction of leadership more broadly, and future scholarship are discussed.

Abstract
Purpose
Organizational pursuit of sustainability in multi-tier supply chain systems operating in unpredictable environments is often associated with the emergence of paradoxical tensions. This study aims to summarize and synthesize existing literature on managing various paradoxical tensions in supply chains (i.e. sourcing, making, delivering and reverse logistics) as organizations pursue sustainability transformation. It also strives to motivate new academic research inquiry into developing responses to sustainability paradoxes.
Design/methodology/approach
The study draws on a systematic literature review of 73 papers from the Web of Science database selected at the intersection of paradox, sustainability and logistics/ supply chain management (SCM). Applying paradox theory as a guiding lens, we investigate organizational strategies, practices and capabilities described in the literature to navigate sustainability paradoxes in supply chains.
Findings
The results assert that the success of sustainability transformation will depend on an organizational ability to recognize, accept and navigate paradoxical tensions in one's supply chain. This requires developing the dynamic capabilities of paradoxical leadership, strategic agility, innovativeness, collaboration with contextualization and governance. Successful sustainability transformation is not reliant on finding an optimal, final design but rather the continuous balancing of tensions inherent within or across the organizations that make up one's supply chain.
Practical implications
The research offers an integrative conceptual framework to guide organizations in navigating sustainability paradoxes in supply chains, embracing strategic, practice and capability levels. It also outlines opportunities for future research inquiries connected to this framework that are needed to build additional insight for addressing paradoxical tensions related to the pursuit of sustainable supply chain management.
Originality/value
This study takes a dynamic capabilities approach to navigating paradoxical tensions in pursuit of sustainable supply chain management.
