Abstract
Purpose
A common design driver for pipe-jacking projects is the jacking force required to advance the tunnel boring machine and pipe string. Empirical methods are popular in industry but are well known to lack accuracy, while there is a strong desire to supplement such approaches with robust data-driven techniques, typically small construction datasets present significant challenges.
Design/methodology/approach
To address this challenge, this paper develops a physics-constrained neural network predictive model for pipe-jacking forces. Information used as input into the model includes principal design information and soil type.
Findings
The physics constrained model was found to predict jacking force to a higher accuracy than current industry practice and better discern meaningful patterns in data than a purely data-driven artificial neural network. The results reveal promising performance for this initial dataset such that there is motivation, as a longer-term objective, to train the present approach on a more comprehensive drive database for more reliable and cost effective solutions for new projects.
Originality/value
Novel contributions include (a) a bespoke framework to constrain a neural network using a pipe-jacking mechanistic model which includes stoppage-induced friction increases, (b) built-in model uncertainty for greater confidence in model outputs, (c) new historical drive data for model training and (d) one-hot encoding of soil type as a model input. The model is calibrated and validated against 14 tunnel drives across four different sites with four distinctive ground types.

Abstract
Purpose
A more accurate comprehension of data elements and the exploration of new laws governing contemporary data in both theoretical and practical domains constitute a significant research topic.
Design/methodology/approach
Based on the perspective of evolutionary economics, this paper re-examines economic history and existing literature to study the following: changes in the “connotation of production factors” in economics caused by the evolution of production factors; the economic paradoxes formed by data in the context of social production processes and business models, which traditional theoretical frameworks fail to solve; the disruptive innovation of classical theory of value by multiple theories of value determination and the conflicts between the data market monopoly as well as the resulting distribution of value and the real economic society. The research indicates that contemporary advancements in data have catalyzed transformative innovation within the field of economics.
Findings
The research indicates that contemporary advancements in data have catalyzed disruptive innovation in the field of economics.
Originality/value
This paper, grounded in academic research, identifies four novel issues arising from contemporary data that cannot be adequately addressed within the confines of the classical economic theoretical framework.

The purpose of this paper is to provide a critical perspective on how the COVID-19 crisis shaped inclusive leadership behaviors of global business leaders.
Abstract
Purpose
The purpose of this paper is to provide a critical perspective on how the COVID-19 crisis shaped inclusive leadership behaviors of global business leaders.
Design/methodology/approach
Using quantitative and qualitative methods, the authors analyzed 240 CEO statements in 120 multinational enterprises from six countries (France, India, Japan, South Korea, UK, USA), pre- and mid-COVID-19.
Findings
Results show that CEO emphasis on inclusive leadership increased during the pandemic. More substantively, the authors identify three key behaviors of inclusive leadership – fidelity, calmness and collective resilience.
Originality/value
The authors provide empirical evidence of inclusive leadership behaviors by global business leaders. In doing so, the authors integrate inclusive leadership into societally engaged international business research.

Abstract
Purpose
This study aims to explore the role of green motive (GM) and green dynamic capabilities (GDC) in green innovation (GI) through green value co-creation (GVC). Moreover, this study investigates the moderation of top management support (TMS) to strengthen the mediation of specific constructs; GM, GDC, green value co-creation (GVC) and green innovation (GI).
Design/methodology/approach
In total, 337 respondents (executive level/chief executive officer (CEO)) of service organizations were approached using a convenience sampling technique to collect the data through the survey method. Of these, 294 (87% response rate) duly filled responses were used in the final data analysis. In SPSS (Statistical Package for Social Sciences) v-23, the Process Macro-Hayes was used to evaluate the study's conceptual framework empirically.
Findings
The study revealed that TMS strengthened the mediation framework of GM, GDC, GVC and GI. Moreover, all hypotheses related to direct and indirect associations of specific constructs used in the theoretical framework were statistically significant and proved.
Originality/value
The comprehensive framework for GI of service organizations, primarily in the context of developing countries like Pakistan, is deficient in literature. This study helps service organizations by providing a comprehensive GI model to put a central focus on the transformation of management philosophy and working approach for achieving GI in the services structure.

Abstract
Purpose
Romanian women migrant entrepreneurs (RWMEs) are amongst the largest EU migrant communities in the UK and make significant socioeconomic contributions to both their host and origin nations, but academic research and policy discussions have ignored them. Intersectionality raises complex contextual issues that require comprehensive examination and inclusive policies and programmes. This study is aimed at exploring how Romanian women migrant entrepreneurs experience their transnational intersectional journeys of belonging, as they create, negotiate and enact their intersectional identities of the country of origin, gender and being entrepreneurs in the UK and Romania.
Design/methodology/approach
This Interpretative Phenomenological Analysis (IPA) draws on draws upon Crenshaw's (1991) intersectional and Social Identity theories (Tajfel and Turner, 1979) to investigate how nine interviewed RWMEs have experienced their transnational journeys of acculturative belonging in the UK and Romania.
Findings
The study findings show how RWMEs undo and negotiate their intersecting identities to adhere to socio-cultural standards in both their host and native nations. In the UK, they feel empowered as women entrepreneurs, but in patriarchal Romania, their entrepreneurial identity is revoked, contradicting the prescribed socio-cultural roles.
Research limitations/implications
This study responds to the call regarding inequalities in entrepreneurship opportunities (Vershinina et al., 2022). By focussing on the understudied community of RWMEs and exploring new intersectional and transnational contextual insights, it contributes to the literature and practice of migrant entrepreneurship. These empirical findings are essential for the development of evidence-based, disaggregated entrepreneurship programmes and policies.

Abstract
Purpose
The purpose of this paper is to systematically analyze the literature around regulatory compliance and market manipulation in capital markets through the use of bibliometrics and propose future research directions. Under the domain of capital markets, this theme is a niche area of research where greater academic investigations are required. Most of the research is fragmented and limited to a few conventional aspects only. To address this gap, this study engages in a large-scale systematic literature review approach to collect and analyze the research corpus in the post-2000 era.
Design/methodology/approach
The big data corpus comprising research articles has been extracted from the scientific Scopus database and analyzed using the VoSviewer application. The literature around the subject has been presented using bibliometrics to give useful insights on the most popular research work and articles, top contributing journals, authors, institutions and countries leading to identification of gaps and potential research areas.
Findings
Based on the review, this study concludes that, even in an era of global market integration and disruptive technological advancements, many important aspects of this subject remain significantly underexplored. Over the past two decades, research has lagged behind the evolution of capital market crime and market regulations. Finally, based on the findings, the study suggests important future research directions as well as a few research questions. This includes market manipulation, market regulations and new-age technologies, all of which could be very useful to researchers in this field and generate key inputs for stock market regulators.
Research limitations/implications
The limitation of this research is that it is based on Scopus database so the possibility of omission of some literature cannot be completely ruled out. More advanced machine learning techniques could be applied to decode the finer aspects of the studies undertaken so far.
Practical implications
Increased integration among global markets, fast-paced technological disruptions and complexity of financial crimes in stock markets have put immense pressure on market regulators. As economies and equity markets evolve, good research investigations can aid in a better understanding of market manipulation and regulatory compliance. The proposed research directions will be very useful to researchers in this field as well as generate key inputs for stock market regulators to deal with market misbehavior.
Originality/value
This study has adopted a period-wise broad-based scientific approach to identify some of the most pertinent gaps in the subject and has proposed practical areas of study to strengthen the literature in the said field.
