Abstract

Purpose

This study examined the dual roles of supervisor-directed surface acting (SDSA) and unfairness talk emerging from low overall justice judgments and the impact of these variables on subordinates' job satisfaction and emotional exhaustion.

Design/methodology/approach

Working professionals (n = 203) were sampled from online panel services in a time-separated data collection design.

Findings

SDSA was found to mediate the relationships of overall justice with emotional exhaustion and job satisfaction. Additionally, unfairness talk reduced the debilitating effect of SDSA on emotional exhaustion, not job satisfaction.

Practical implications

The paper highlights the importance of supervisors understanding the problematic nature of ongoing interactions with subordinates after unjust events occur.

Originality/value

This study helps to better explain why overall justice assessments influence subordinates' job satisfaction and emotional exhaustion. Additionally, the findings show that unfairness talk may not be as detrimental as suggested in recent studies, and it acts as a coping mechanism when contending with high SDSA, especially when emotional exhaustion is considered.

Abstract

Purpose

The purpose of this paper is to provide an update to the Supply Chain Volatility Index (SCVI), and expand on prior work by presenting a conceptual framework illustrating how firms can deal with persistent volatility, the ensuing risk and mitigate the cost implications for their supply chain operations.

Design/methodology/approach

The authors use long-term time series of secondary data to assemble a “basket” of key indicators that are relevant to the business context within which global supply chains operate. The authors also report on five years of feedback gained from presentations of the SCVI to scholars and practitioners.

Findings

Volatility has reduced from record levels experienced during the global financial crises, yet remains at levels considerably higher than prior to the crisis, with no sign of a return to the more stable conditions that prevailed when many current supply chain networks were designed.

Research limitations/implications

The authors reaffirm that new mental models are needed which embrace volatility as a factor in supply chain design, rather than seek to eradicate it in supply chain operations. Traditional static “network optimisation” based on a simple definition of low unit cost seems no longer appropriate under conditions of persistent volatility.

Practical implications

The authors provide a conceptual link of volatility, risk and cost in the supply chain, and outline how firms can develop a supply chain strategy by managing their exposure to volatility.

Originality/value

The authors challenge the common assumption that volatility invariably leads to risk and higher cost in the supply chain. Instead the authors argue that the supply chain structure can mitigate the exposure to supply chain risk. The authors introduce the concepts of recovery and resilience cost within a framework designed to help firms manage volatility-induced risk by minimising the adverse cost implications of volatility in their supply chains.

Abstract

Purpose

An emerging theme in the practitioner literature suggests that the supply chain of the future – enabled especially by developments in ICT – will be autonomous and have predictive capabilities, bringing significant efficiency gains in an increasingly complex and uncertain environment. This paper aims to both bridge the gap between the practitioner and academic literature on these topics and contribute to both practice and theory by seeking to understand how such developments will help to address key supply chain challenges and opportunities.

Design/methodology/approach

A multi-disciplinary, systematic literature review was conducted on relevant concepts and capabilities. A total of 126 articles were reviewed covering the time period 1950-2018.

Findings

The results show that both IoT and AI are the technologies most frequently associated with the anticipated autonomous and predictive capabilities of future supply chains. In addition, the review highlights a lacuna in how such technologies and capabilities help address key supply chain challenges and opportunities. A new supply chain model is, thus, proposed, one with autonomous and predictive capabilities: the self-thinking supply chain.

Originality/value

It is our hope that this novel concept, presented here for the first time in the academic literature, will help both practitioners to craft appropriate future-proofed supply chain strategies and provide the research community with a model (built upon multidisciplinary insights) for elucidating the application of new digital technologies in the supply chain of the future. The self-thinking supply chain has the potential in particular to help address some of today’s key supply chain challenges and opportunities.

Abstract

Purpose

The purpose of this paper is to provide a snapshot of secondary school food policy (SSFP) across the devolved nations (England, Scotland, Wales and Northern Ireland) to offer insights into a growing area of policy concern. The selected context of research is school food policy (SFP), an area of research which has received little attention in terms of policy approaches. The review is focused on 2010 to 2022.

Design/methodology/approach

This work combines interdisciplinary perspectives spanning across food policy, public health, psychology, education and sociology. This combination has merit as it offers different perspectives in terms of understanding SFP. The study was conducted between August 2021 and March 2022, using a desk-based review, analysing policies on food in secondary schools. Data collection was conducted through the Web using key search terms. The READ (Read, Extract, Analyse, Distil) approach was used as a systematic procedure to analyse policy and evaluation documents.

Findings

To all levels of government, it is recommended that a coherent policymaking approach be used to tackle SSFP improvements, to progress a whole school approach to food, supported by long-term dedicated resources while engaging children in SSFP development. For education departments, it is recommended that a food curriculum review, connected to school meals alongside a refocus on school food standards monitoring and reporting is crucial in serving the future generations. The current economic crisis has had an impact on public spending. Universal Free School Meals has been said to make an enormous difference to well-being.

Originality/value

The current findings suggest that researching SFP across nations has merit. There is a relative lack of focus on secondary schools, in light of England’s focus on the National Food Strategy (focus on children), post-pandemic, economic crisis – together this makes school food and food policy a topic of real urgency and importance. Lessons can both be learned, particularly in promoting healthier and more educationally inclusive school food practices. Research in this area can inform curriculum design and school food environment and system changes from the perspective of learnings around taking a whole school food approach to education.

Abstract

Purpose

Investigating the beginning of project management (app. 30 BC) with a focus on business models similar to the “PDCA” cycle, the purpose of this paper is to find an approach which could be used as a new standard procedure for the eradication of projects in Lean project management.

Design/methodology/approach

Based on literature research of models similar to Walter A. Shehwart’s three-step and Edward W. Deming’s four-step (PDC(A)) wheel, the investigated models are interconnected to form a new concept which represents an innovative cycle logic proposed to be applied in Lean project management. This new cycle logic is rolled out on three different levels, which are transferred from the Lean management hoshin kanri model to Lean project management. In addition to literature research, semi-structured interviews were performed to get an indication as to the integration of Lean management (with a focus on PDCA) in project management today.

Findings

It was found that the “Check Plan Do” cycle is a Lean variant of the “Plan Do Check Act” model that is already used in consulting projects in practice, partially appears in project management standards, in governance models of ambulance, fire services, human aid and military forces and in quality management models of Six Sigma, design for Six Sigma and an excellence model of the European Foundation for Quality Management. To ensure continuous improvement it was found that the new CPD cycle can be used on different “planning” levels in analogy to the hoshin kanri logic.

Originality/value

To the best of the author’s knowledge, a discussion as to how the PDCA cycle can be adapted to Lean project management, considering the implication of business models similar to the PDCA wheel, has not yet been conducted within the field of project management.

Abstract

Purpose

Additive manufacturing (AM) techniques have been developed to rapidly produce custom designs from a multitude of materials. Bonded permanent magnets (PMs) have been produced via several AM techniques to allow for rapid manufacture of complex geometries. These magnets, however, tend to suffer from lower residual induction than the industry standard of injection moulding primarily due to the lower packing density of the magnetic particles and secondly due to the feedstock consisting of neodymium-iron-boron (Nd-Fe-B) powder with isotropic magnetic properties. As there is no compaction during most AM processes, increasing the packing density is very difficult and therefore the purpose of this study was to increase the magnetic properties of the PMs without increasing the part density.

Design/methodology/approach

Accordingly, this research investigates the use of anisotropic NdFeB feedstock coupled with an in-situ alignment fixture into an AM process known as selective laser sintering (SLS) to increase the magnetic properties of AM magnets. A Helmholtz coil array was added to an SLS machine and used to expose each powder layer during part fabrication to a near-uniform magnetic field of 20.4 mT prior to consolidation by the laser.

Findings

Permeagraph measurements of the parts showed that the alignment field introduced residual induction anisotropy of up to 46.4 ± 2.2% when measured in directions parallel and perpendicular to the alignment field. X-ray diffraction measurements also demonstrated a convergence of the orientation of the crystals when the magnets were processed in the presence of the alignment field.

Originality/value

A novel active alignment fixture for SLS was introduced and was experimentally shown to induce anisotropy in bonded PMs. Thus demonstrating a new method for the enhancement in energy density of PMs produced via AM methods.

Abstract

One of the less observed results of transportation deregulation has been the explosive growth of transportation intermediaries or third‐party specialists such as brokers, shippers' agents and integrated leasing companies for use by industrial purchasers and marketing management. Such transportation intermediaries have the performance potential and apparent reasons for existence to suggest that they can both reduce delivered product costs and enhance service quality attributes to promote a company's competitive advantage. In a broader sense, intermediaries may be ideally positioned to assist in coordinating and processing information for the entire value‐added chain.

Abstract

Purpose

This paper offers a retrospective on the launch and first volumes of this journal. It describes the history of a unique period in our discipline when founding fathers in the US and UK collaborated with industry and each other to create a new field.

Design/methodology/approach

The authors interviewed founding editor Professor Martin Christopher and coeditor in Chief Professor Doug Lambert, conducted a bibliometric review of the first volumes of the journal and informed the analysis by approaches taken in other retrospectives published in the journal. The authors also feature historical artifacts from the journal.

Findings

The editorial focus during the early days of the journal demonstrate how the roots of the field are in cost modeling and technical work but quickly moved toward customer orientation and managerial focus. The editorial approach during the early days of the journal was on innovative research and publishing, scholarship engaged with industry, a focus on relevance and industry impact as well as leveraging research in education.

Originality/value

There have been retrospectives on the journals most recent volumes but what the authors aim to do is to reflect upon the launch and the first volumes of the journal. The authors expand and further detail the timeline of the development of the logistics field. In the process, the authors identify several historical roots for topics of greater focus in logistics and supply chain management in later years. The authors also find that many of the essential approaches and lessons learned in the period leading up to the launch and shortly after the launch of the journal do not only capture the early development of the discipline it also offers an approach and model for scholarship worthy of consideration still today. On top of that, several of the lessons learned in that period hold high relevance still today and they imply part of the path forward for the discipline and the journal, the authors develop questions for future research and research and editorial strategies.
