Abstract

Purpose

The purpose of this paper is to examine the impact of renewable energy on the power supply chain and to study whether the renewable generator or the power grid that purchases power from the power spot market is better when the actual generation of renewable energy is insufficient. The authors want to compare and analyze the different power supply chain operation modes and discuss the optimal mode selection for renewable energy generator and power grid in different situations.

Design/methodology/approach

This paper studies the grid-led price competition game in the power supply chain, in which the power grid as a leader decides the price of transmission and distribution, and generators determine the power grid price. The renewable energy power generator and the traditional energy power generator conduct a price competition game; on the other hand, the power grid and power generators conduct Stackelberg games. The authors analyze the power supply of single power generator and two power generators, respectively, and research on the situation that the renewable energy cannot be fully recharged when the actual power generation is insufficient.

Findings

The study finds that both renewable and traditional power grid prices decline as price sensitivity coefficient of demand and installed capacity of renewable energy generators increase. Power grid premium decreases as the price sensitivity coefficient of demand increases, but rises as the installed capacity of renewable energy generator increases. When there is a shortage of power, if the installed capacity of renewable energy is relatively small and price sensitivity coefficient of demand is relatively large, the grid purchases the power from power spot market and shares cost with renewable energy generators, leading to higher expected profits of the renewable energy generators. On the contrary, the renewable energy generators prefer to make up power shortage themselves. For the power grid, purchasing the power by the renewable energy generators when there is a power shortage can bring more utility to the power grid when the installed capacity of renewable energy is lower and the demand price sensitivity coefficient is higher. When the installed capacity of renewable energy is high and the price sensitivity coefficient of demand is moderate, or the installed capacity of renewable energy is moderate and the demand price sensitivity coefficient is high, a generator that simultaneously possesses two kinds of energy source will bring more utility to the power grid. If the installed capacity of renewable energy and the demand price sensitivity coefficient both are small or the installed capacity of renewable energy and the price sensitivity coefficient of demand both are large, the power grid prefers to purchase the power by itself when there is a power shortage.

Practical implications

The goal of our paper analysis is to explore the implications of the theoretical model and address the series of research questions regarding the impact of the renewable energy on the power supply chain. The results of this study have key implications for reality. This paper sheds light on the power supply chain operation mode selection, which can potentially be used for the renewable energy generators to choose their operating mode and can also help traditional energy generators and power grid enterprises maximize their utility. This paper also has some references for the government to formulate the corresponding renewable energy development policy.

Originality/value

This paper studies the power operation mode under the uncertainty of supply and demand, and compares the advantages and disadvantages of renewable energy generator that makes up the shortage or the power grid purchases the power from power spot market then shares cost with the renewable energy generator. This paper analyzes the power grid-led coordination problem in a power supply chain, compares and analyzes the price competition game model of single power generator and dual power generators, and compares the different risk preferences of power grid.

Abstract

Purpose

The purpose of this paper is to explore how one can prevent the flaws or dark sides of the globalisation process from leading to ever‐greater decay of responsibility. By decay of responsibility, is meant the threat that globalisation poses to what is referred to by philosophers such as David Harvey, John McMurtry and Paul Ricoeur, as the longing for being and solidarity with the other(s).

Design/methodology/approach

To put a stop to the decay of responsibility, the urgency of a broader ethical dimension in globalisation is more apparent than ever before. The threat the globalisation process poses to the longing for being and solidarity with the other(s), increasingly necessitates an appropriate responsible global institution.

Findings

Of central importance are the principles of merit and need as possible basis of a responsible institution. The intrinsic logic of the merit principle incorporated in the growth process of globalisation, induces a series of impermissible side effects. Therefore, the traditional correction of democracy giving priority to the principle of need instead of merit, no longer appears to counteract the market economy to be able to provide guarantees for a responsible globalisation process.

Research limitations/implications

Politics needs to assure the survival of the social community, all the more so if its future is under considerable threat. The acceptance of responsibility implies also the care for the most fragile.

Practical implications

The paper explains the need of an ethics of responsibility that transcends the excessive ego‐centric globalised society. Therefore, participatory or responsible justice is considered to be of the utmost importance. Participation should be broadly interpreted and include policy makers, environmentalists, scientists, economists, lawyers, ethicists, consumers, farmers and other representatives of civil society.

Originality/value

The present worldwide economic, social and ecological crises have created fertile ground for claiming the need for an internationally recognized charter setting out human responsibilities. The concept of a Charter of Human Responsibilities can be an original elaboration of the concern with institutionalising responsibility.

Abstract

Purpose

The purpose of this paper is to explore the dark side of supermarket-driven sustainable dairy supply chains. This paper raises questions about the unintended consequences of implementing sustainable supply chain management in the dairy food supply chain. It critically questions whether unintended consequences were actually, anticipated, as the course of action taken by retailers reinforces the dominant profitability discourse.

Design/methodology/approach

Through a critical management studies approach, this paper challenges the dominant discourse to shed light on the social consequences of the win-win sustainable supply chain management in the dairy food supply chain. The focus of this paper is on the experiences of farmers, taking their viewpoint of sustainable supply chains rather than taking the perspective of the multinationals who have traditionally been the focus of supply chain management research (e.g. McCarthy et al., 2018; Quarshie et al., 2016).

Findings

The study illuminates how retailers have bolstered their dominant position through using sustainable supply chains to exert further control over their suppliers. The management of sustainable supply chains has been a further catalyst in economically and socially dividing rural communities and creating tensions between dairy farmers.

Originality/value

This paper uses an ethnographic study to provide in-depth stories of the changes that took place within one farming community. It exposes the hidden ways in which the introduction of a sustainable dairy supply chain has created social and economic division, further reducing the collective power of dairy farmers through creating a dual supply chain.

Abstract

Purpose

The purpose of this paper is to investigate how three core elements of critical management studies (CMSs), “de-naturalisation”, “reflexivity” and “(non)-performative intent”, can help expand the current debate in the supply chain management (SCM) field.

Design/methodology/approach

The authors used a systematic literature review to select 103 articles published in 12 high-ranking journals in the SCM field based on the Academic Journal Guide of the Chartered Association of Business Schools.

Findings

The findings of this study suggest that SCM studies can be narrowed down into four major CMSs themes: “power”, “ethics and environmental issues”, “diversity” and “working conditions”, but even these themes are still under-discussed and undertheorized in SCM. The literature the authors reviewed is more concerned with explaining these phenomena than questioning them and proposing new agendas. This paper, therefore, will discuss how these three core elements of CMS can help transform the “hidden” issues of SCM, which it will do by illustrating it in the context of buyer–supplier relationships and lean manufacturing.

Practical implications

This research will encourage SCM scholars who are interested in conducting more critical studies and teaching the harmful effects of global supply chains.

Originality/value

This paper highlights that a combination of SCM and CMS approaches is important when we decide to adopt a more critical “constructive” view of supply chain challenges and engage practical and critical views, respectively, to generate knowledge that not only increases (corporate) performance but also highlights social needs and values.

Abstract

Purpose

With the improvement of consumers' health consciousness, healthy food has attracted great attention in daily consumption. Previous research into the sense of power often distinguishes it into high and low level, ignoring the impact of different construal of power on consumption behaviors. This article divides power into dual construal (responsibility vs opportunity) and aims to examine the differential impacts of the construal of power on healthy food preference.

Design/methodology/approach

Two pretests and three formal experiments were conducted to examine the effect of the construal of power on the consumer's healthy food preference, the mediation of self-discipline perception and the moderation of the relative strength of prevention over promotion focus (i.e. RSPPF).

Findings

Results indicate that individuals who construe power as responsibility (vs opportunity) exhibit higher self-discipline perception, which in turn leads to greater healthy food preference. However, the main effect above can be weakened among the low-power group. Moreover, the above mediating effect of self-discipline perception is stronger for individuals with higher RSPPF.

Originality/value

First, based on the binary-construal perspective, this study refines the classification of high power and introduces it into the antecedent research of healthy food preference. Second, this paper reveals the self-discipline perception as the inner mechanism underlying the effect of the construal of power on healthy food preference, while RSPPF as the boundary condition for this mediating mechanism. Moreover, this research also provides practical implications for healthy food enterprises that the construal of power, self-discipline perception and regulatory focus should be taken into consideration in advertising design and healthy product promotion.

Abstract

Purpose

Despite the many advantages this type of equipment offers, there are still some major drawbacks. Linear cutting machine (LCM) cannot accurately simulate the true rock-cutting process as 1. it does not account for the circular path along which tunnel boring machine (TBM) disk cutters cut the tunnel face, 2. it does not accurately model the position of a disk cutter on the cutterhead, 3. it cannot perfectly replicate the rotational speed of a TBM. To enhance the knowledge of these issues and in order to mimic the real rock-cutting process, a new lab testing equipment was developed by Hyundai Engineering and Construction.

Design/methodology/approach

A new testing machine called rotary cutting machine (RCM) is designed to simulate the excavation process of hard-rock TBMs and includes features such as TBM cutterhead, RPM simulation, constant normal force mode and constant penetration rate mode. Two sets of tests were conducted on Hwandeung granite using different disk cutter sizes to analyze the cutting forces in various excavation modes. The results are analyzed using statistical analysis and dimensional analysis. A new model is generated using dimensional analysis, and its results are compared against the results of actual cases.

Findings

The effectiveness of the new RCM test was demonstrated in its ability to apply various modes of excavation. Initial analysis of chip size revealed that the thickness of the chips is largely dependent on the cutter spacing. Tests with varying RPM showed that an increase in RPM results in an increase in the normal force and rolling force. The cutting coefficient (CC) demonstrated a linear correlation with penetration. The optimal specific energy is achieved at an S/p ratio of around 15. However, a slightly lower S/p ratio can also be used in the design if the cutter specifications permit. A dimensional analysis was utilized to develop a new RCM model based on the results from approximately 1200 tests. The model's applicability was demonstrated through a comparison of TBM penetration data from 26 tunnel projects globally. Results indicated that the predicted penetration rates by the RCM test model were in good agreement with actual rates for the majority of cases. However, further investigation is necessary for softer rock types, which will be conducted in the future using concrete blocks.

Originality/value

The originality of the research lies in the development of Hyundai Engineering and Construction’s advanced full-scale laboratory rotary cutting machine (RCM), which accurately replicates the excavation process of hard-rock tunnel boring machines (TBMs). The study provides valuable insights into cutting forces, chip size, specific energy, RPM and excavation modes, enhancing understanding and decision-making in hard-rock excavation processes. The research also presents a new RCM model validated against TBM penetration data, demonstrating its practical applicability and predictive accuracy.

Abstract

Purpose

The purpose of this study is to analyse the role of relational power/dependent asymmetries and symmetries in shaping socially responsible supply chain management, whilst also examining how these issues are moderated by geographical distance between buyer and supplier.

Design/methodology/approach

The study draws on data from 339 buyer‐supplier relationships, and the authors use a set of regression models to test their hypotheses.

Findings

Joint dependency positively influences socially responsible supply chain management, whilst supplier power constrains it. Both joint dependency and buyer power become increasingly important determinants of socially responsible supply chain management as geographic distance increases.

Research limitations/implications

Further work is needed to examine the conditions under which organisations will exercise their power advantage or their joint dependence position to improve socially responsible processes in the supply chain, as there may be situations where the buyer chooses not to exercise their power positions.

Practical implications

The authors' results indicate that jointly dependent relationships create the best conditions for socially responsible supply chain management, but they also find that supplier power advantage can constrain such initiatives.

Originality/value

This is the first paper to systematically analyse the implementation of socially responsible supply chain management, within a model that considers power a/symmetric positions of the buyer‐supplier relationship, and the role of geographical distance as a moderating influence on these power positions.

Abstract

Purpose

This paper aims to discuss how religiously and non-religiously affiliated individuals may view the three core workplace spiritual values: transcendence, existence of a higher power and interconnectedness. Additionally, this paper studies how the contrasts between the views of religiously and non-religiously affiliated individuals about the three core spiritual values affect their performance of social responsibility initiatives.

Design/methodology/approach

A conceptual analysis was used.

Findings

This paper suggests that religiously and non-religiously affiliated individuals view the three core spiritual values differently. Drawing upon the three core spiritual values viewed by religiously and non-religiously affiliated individuals, this paper proposes the following. First, religiously affiliated individuals will focus on implementing social responsibility initiatives for a longer time orientation compared to non-religiously affiliated individuals. Second, when engaging in social responsibility, religiously affiliated individuals will focus on implementing a smaller scope of social responsibility initiatives than non-religiously affiliated individuals. Finally, religiously affiliated individuals will focus on implementing a larger scale of social responsibility initiatives than non-religiously affiliated individuals.

Originality/value

This paper is one of the very first studies addressing how religiously and non-religiously affiliated individuals view core values of spirituality. Additionally, this paper advances the literature by contrasting how religiously and non-religiously affiliated individuals engage in socially responsible initiatives in accordance with how they view spirituality.

Abstract

In 2004, the Canadian government appointed an ethics commissioner reporting directly to Parliament. I show how an appeal of the ethics commissioner finds its traction in three problem areas. First, there is an increasing distaste in Canada for patronage and other similar forms of partisanship in politics, but there is general uncertainty about the constitutional or ethical standards that ought to apply. Second, the language of democratic criticism and reform of Parliament is rooted less in actual constitutional practice than in an idealized sense of how Parliament ought to work, a problem that is exacerbated by the ongoing presence of the American example. Finally, these both feed into a growing disengagement from traditional party politics and a desire for more “independent” or non-partisan checks on government, of which the Office of the Auditor General is becoming a popular exemplar. As an independent, Parliamentary, and non-partisan check on government, the ethics commissioner appears to serve as at least a partial solution to much of what is wrong with the Canadian political system.
