Abstract

Purpose

The purpose of this paper is to study the effects of printing strategies and processing parameters on wall thickness, microhardness and compression strength of Inconel 718 superalloy thin-walled honeycomb lattice structures manufactured by laser powder bed fusion (L-PBF).

Design/methodology/approach

Two printing contour strategies were applied for producing thin-walled honeycomb lattice structures in which the laser power, contour path, scanning speed and beam offset were systematically modified. The specimens were analyzed by optical microscopy for dimensional accuracy. Vickers hardness and quasi-static uniaxial compression tests were performed on the specimens with the least difference between the design wall thickness and the as built one to evaluate their mechanical properties and compare them with the counterparts obtained by using standard print strategies.

Findings

The contour printing strategies and process parameters have a significant influence on reducing the fabrication time of thin-walled honeycomb lattice structures (up to 50%) and can lead to improve the manufacturability and dimensional accuracy. Also, an increase in the young modulus up to 0.8 times and improvement in the energy absorption up to 48% with respect to those produced by following a standard strategy was observed.

Originality/value

This study showed that printing contour strategies can be used for faster fabrication of thin-walled lattice honeycomb structures with similar mechanical properties than those obtained by using a default printing strategy.

Abstract

Purpose

This paper aims to analyse the relationships between management innovation, marketing innovation, technological innovation and the personnel involved in science, technology and innovation activities.

Design/methodology/approach

The work used data from the Technological Development and Innovation Survey – Colombian Industry VII 2013–2014. Six logistic regression models are tested for the analysis with 2,045 manufacturing firms.

Findings

The results suggest that the probability to pursue technological innovation diminishes in those firms that introduce management and/or marketing innovations. The same happens in firms seeking non-technological innovations with the introduction of product and process innovations. The human side, administrative and technical staff, working on innovation projects plays a key role in the success of different types of innovations.

Originality/value

At this time, there is a need for research studies with new approaches that look at innovation beyond the technological domain and focus on the human side of innovation and other important aspects such as the managerial contribution to innovation. Theoretically, the work contributes to expanding the scarce literature on the proposed relationship and, as far as is known, it is the only one with empirical data for an emerging economy such as the Colombian one. Empirically, useful information is provided for the design of strategies that seek to improve firms' innovation performance.

Abstract

Purpose

This paper aims to assess what happens to a willingness to take entrepreneurial action when people experience low or high subjective well-being (SWB) in 12 emerging economies.

Design/methodology/approach

The research uses principal component analysis (PCA) and logistic regressions with a data sample from the global entrepreneurship monitor (GEM) for emerging economies.

Findings

The main results suggest that SWB, measured as satisfaction with life (SWL) and job satisfaction (JOBS), increases the probability of a person becoming an entrepreneur.

Social implications

The findings of this research suggest that designing and implementing public policies that seek to promote the well-being of individuals might foster their entrepreneurial activities in emerging economies.

Originality/value

The literature on entrepreneurship, which assesses its relationship with SWB is still scarce. Most of the academic work has been carried out for developed countries, mainly analysing how entrepreneurial activity affects SWB in self-employees or entrepreneurs. This manuscript analyses these elements in the opposite direction, contributing to an underdeveloped discussion on how well-being affects the decision to be an entrepreneur.

Abstract

Purpose

The main purpose of this review is to enhance the understanding of intellectual structure and outlook of management innovation research as an interesting and growing research field.

Design/methodology/approach

This systematic literature review examines the question, what is the relationship of management innovation with the performance of companies and with other types of innovation? The work also pursues to summarize theories, contexts, characteristics of the papers and methodologies with the purpose of facilitating further development and opportunities and priorities for future research.

Findings

The results suggest that management innovation is an interesting and growing research field; in its relation to different types of innovation and performance, it is a field explored with theoretical approaches, contexts and methodologies that begin to form a consolidated body of knowledge. However, through a critical analysis, this review highlights the gaps in the literature and provides suggestions for future studies to further explore the field. This revision contributes to the literature on management innovation summarizing the findings and contributions of research published in the field and its relationships with innovation and performance. It then identifies three comprehensive research streams, namely, future research on conceptualization, definitions and measurements; research on the level of analysis; and future research on management innovation drivers, antecedents and use as mediator/moderator variables.

Originality/value

Management innovation is an emerging research field that is characterized as a branch of research long ignored by more orthodox lines dedicated to technological innovation and topics in product and service development research.

Abstract

Purpose

The purpose of this study is to analyze the relationship between lean manufacturing and corporate environmental performance. Scholarly literature has extensively addressed the relationship between those two areas but empirical papers present mixed and inconsistent results, calling for further analysis to establish a clearer understanding of the actual relationship and to identify the causes of conflicting findings across studies. Given the importance of sustainable practices in the current business landscape, this paper aims to provide a comprehensive overview of this relationship through a meta-analysis of previous research, with a focus on integrating quantitative findings to shed light on the potential impact of lean manufacturing on environmental performance and report its intensity with Pearson’s correlation coefficient.

Design/methodology/approach

This paper analyzes the data from 29 primary studies published between 2001 and 2022 that have empirically measured the relationship between lean manufacturing and corporate environmental performance and that have been identified in the Web of Science and SCOPUS databases through an exhaustive review of the literature. To integrate previous empirical results and evaluate the evidence for the lean manufacturing’s influence on environmental performance, a meta-analytic methodology was adopted through the Hedges–Olkin random effect approach, based on correlations.

Findings

Main findings support the notion that a significant, positive, rather moderated, relationship exists between lean manufacturing and environmental performance, with an overall correlation coefficient r¯ = 0.25. The result seems robust, as several tests confirm that publication bias is unlikely. Overall, various lean practices are correlated to varying degrees with different measures of environmental performance. The environmental efficiency of external lean practices is higher than that observed for internal practices and quality management has a more pronounced effect than other internal lean practices. The 2008 global crisis did not change these relationships and the impact of lean manufacturing on environmental performance does not seem to be moderated by the degree of environmental awareness of the country where applied.

Research limitations/implications

The results conclude that a significant, positive relationship exists between lean manufacturing and environmental performance (r¯ = 0.25). This study tests certain factors that exhibit varying effect sizes and moderate the overall outcome, highlighting that the environmental efficiency of external lean practices is higher than that observed for internal practices. In addition, it suggests a more pronounced effect of quality management among other internal lean practices.

Practical implications

This study provides companies with an opportunity to align their operational strategies with environmental sustainability goals. Understanding that various lean practices exhibit diverse levels of correlation with multiple measures of environmental performance, decision-makers can prioritize their efforts and apply the lean practices that have a stronger effect on the desired environmental outcomes to improve their environmental impact. Conversely, managers are aware that certain lean practices have a week relationship with some environmental performance so they can avoid overestimating environmental benefits of lean manufacturing. Finally, results underscore the importance of organizational commitment to environmental sustainability.

Originality/value

It is, to the best of the authors’ knowledge, the first meta-analytic study to investigate the strength of the association between lean manufacturing and environmental performance and to test whether various lean practices are correlated to different measures of environmental performance. It fills this gap in the literature and therefore it represents a valuable contribution to the field. In addition, this paper explores certain factors that moderate the overall outcome.

Abstract

Summary

Many of the human communities that comprise the South have cosmologies that place human and nonhuman animals on a continuum. Culturism, with its foreign logic and dynamics, has broken this continuum, thereby fuelling speciesist practices. In this chapter, I portray the deep relation that some rural Southern communities have with nonhuman animals, and analyse some of the imposed logics that lead the South to abuse nonhuman animals while denying that what they are doing is mistreatment.

Abstract

Purpose

This study aims to examine the differential impact of ride-hailing services (RHS) on private and commercial vehicle ownership from five metropolitan cities in India.

Design/methodology/approach

Using vehicle ownership data from five metropolitan cities over period 1991 to 2020, a panel corrected standard errors model was estimated to model the association between RHS and vehicle ownership.

Findings

The results indicate that advent of RHS has led to a significant reduction in private vehicle ownership rates and a corresponding increase in addition of intermediate public transport. The net effects of RHS on road congestion and pollution levels need to be studied in detail.

Practical implications

The findings of this study can potentially assist policymakers and mobility planners in efforts to decarbonise and decongest urban transport.

Originality/value

This study sets precedence in analysing the impact of RHS on private and commercial vehicle independently. Further, to the best of the author’s knowledge, this is the first study to examine this association for the city of Delhi and Kolkata.

Abstract

Purpose

The purpose of this study is to investigate the perceived effects between soft management practices, employee behaviours and the implementation of digital technologies in manufacturing plants, as well as how these relate to the emergence of digital waste.

Design/methodology/approach

This paper uses case-based research. Data was collected in two large manufacturing companies based in Norway and Sweden through semi-structured interviews with two management representatives and four shop-floor employees. The data was used to evaluate 29 variables describing lean- and total quality management (TQM)-associated employee behaviours and soft management practices, in light of digital transformation.

Findings

The results suggest that several variables were positively influenced by the digital transformation process. These were top management leadership, middle management involvement, employee education, corporate social responsibility focus, innovation, knowledge sharing, work-family balance, psychological capital, job satisfaction and career commitment. Training employees, creativity, discretionary effort, turnover intention and proactivity appear to be negatively influenced by digital transformation The findings also indicate that several soft management practices and employee behaviours were not only influenced by manufacturing digitalization but also themselves influenced the process. The potential for digital waste creation was also detected in several variables, including reward and recognition and training employees.

Practical implications

Managers, practitioners and academics may learn about the importance of certain managerial practices and employees’ behavioural needs during the digital transformation process. The findings may help in prioritizing TQM and soft lean management practices and certain employee behaviours during the digital transformation and in creating awareness of digital waste.

Originality/value

This study builds on several existing studies discussing the impact of digital transformation on soft management practices and employee behaviours. It provides insights from a lean and TQM angle and offers a means of prioritizing certain practices and behaviours during a digital transformation. This study also highlights the significance of digital waste.

Abstract

Purpose

Grounded on the emotion regulation theory, this study aims to examine how and when entrepreneurial fear of failure decreases the well-being of entrepreneurs. It mainly investigates a moderated mediation model, including emotion regulation as a mediator in the association between entrepreneurial fear of failure and psychological well-being and resilience as the moderator between entrepreneurial fear of failure and emotion regulation.

Design/methodology/approach

For this study, the primary data was gathered using a reflective-formative scale of entrepreneurial fear of failure from micro-, small- and medium-sized business owners from Lucknow, the capital of India’s most populous state. Hypothesis testing was done using partial least squares structural equation modeling on 250 valid responses.

Findings

The findings suggested that fear of failure has a damaging consequence on the psychological well-being of entrepreneurs, and this link is mediated through emotion regulation. In addition, resilience was observed to moderate the link between fear of failure and emotion regulation among entrepreneurs. Furthermore, resilience moderates the indirect impact of emotion regulation concerning fear of failure and well-being among micro-, small- and medium-sized business owners.

Practical implications

The study offers theoretical and practical implications, as the results highlight the role of emotion regulation and resilience in handling the adverse outcomes of entrepreneurial fear of failure. The study asserts that business owners need to learn ways to control their emotions and be resilient to face the destructive consequences of entrepreneurial fear of failure.

Originality/value

The study marks a novel role by unfurling the underlying psychological mechanisms in the association concerning fear of failure and the well-being of existing entrepreneurs from India by examining the moderated mediation model to understand the relationships better. This study is one of the pioneer attempts to uncover the moderating role of resilience and the mediating effect of emotion regulation to explain the outcome of entrepreneurial fear of failure.
