Abstract
Purpose
This study aims to understand the difference between irreversibility in heat and work transfer processes. It also aims to explain that Helmholtz or Gibbs energy does not represent “free” energy but is a measure of loss of Carnot (reversible) work opportunity.
Design/methodology/approach
The entropy of mass is described as the net temperature-standardised heat transfer to mass under ideal conditions measured from a datum value. An expression for the “irreversibility” is derived in terms of work loss (Wloss) in a work transfer process, unaccounted heat dissipation (Qloss) in a heat transfer process and loss of net Carnot work (CWnet) opportunity resulting from spontaneous heat transfer across a finite temperature difference during the process. The thermal irreversibility is attributed to not exploiting the capability for extracting work by interposing a combination of Carnot engine(s) and/or Carnot heat pump(s) that exchanges heat with the surrounding and operates across the finite temperature difference.
Findings
It is shown, with an example, how the contribution of thermal irreversibility, in estimating reversible input work, amounts to a loss of an opportunity to generate the net work output. The opportunity is created by exchanging heat with surroundings whilst transferring the same amount of heat across finite temperature difference. An entropy change is determined with a numerical simulation, including calculation of local entropy generation values, and results are compared with estimates based on an analytical expression.
Originality/value
A new interpretation of entropy combined with an enhanced mental image of a combination of Carnot engine(s) and/or Carnot heat pump(s) is used to quantify thermal irreversibility.

Abstract
Reports the results of two experimental tests of the extent to which the large disparity between people’s valuation of gains and losses, and related fairness determinations, are used in judging the acceptability of alternative negotiating or conflict resolution proposals. Participants acted as arbitrators and selected their preferred resolution of conflicts, involving either the division of gains or sharing responsibility for losses. Different cases were presented in which one or the other party incurred varied combinations of direct or opportunity costs, or received varied forms of payments. Contrary to conventional economic assumptions, but consistent with earlier behavioural findings, direct costs incurred by one party to the negotiation were far more important than opportunity costs in setting the terms of a more acceptable resolution. The results strongly suggest that recent behavioural findings might be used to improve the design of negotiating and conflict resolution proposals.

Abstract
Purpose
One of most important tools for lean production is value stream mapping (VSM), which identifies and reduces errors, losses, waiting time and improves value adding time, leading to enhanced product quality through empowering production unit in terms of production risk and cost reduction in the long term. This paper aims to present a general concept for production flow, such that value stream can be fully understood. For this purpose, this research investigates the effect of value stream on operational losses and analyzes the process that has been conducted in preview step operationally, using the discovered pattern.
Design/methodology/approach
In this research, related processes were evaluated after the review of the relevant literature and after extracting operational basics of lean approach using a questionnaire, such that all factors affecting operational losses and VSM were assessed. Then comparison between the result of current state map and the result of future state map were done and analyzed. Cronbach’s alpha was calculated to test the designed questionnaire’s reliability, which resulted in an acceptable level of 0.845. The structural equation modeling method through SPSS and Smart–Partial Least Square was applied to analyze the data and test the hypotheses.
Findings
The results reveal that implementing required changes and corrections will lead directly to production process improvement, which, in turn, results in higher customer satisfaction because of cost reduction and quality enhancement. Also, tests of the hypotheses confirm that VSM affects six operational losses, namely, equipment failures, set-up and changeovers, idling and minor stoppages, reduced speed operation, scrap and rework and startup losses.
Research limitations/implications
Though this study was done in a single manufacturing company, the implementation of this study delivers important results that can be deployed in other such manufacturing companies.
Practical implications
This tool helps to identify loss points, make right decisions, and choose the best methods and lean tools for improvement. The surveyed company can integrate lean principles and tools and achieve better results using this tool. Also, this tool could be used to analyze the process and to define necessary changes before changing the process components.
Originality/value
This study contributes to the body of knowledge in manufacturing research as the study regarding the effects of improvement opportunities identified through VSM on operational losses is still something new.

Abstract
Purpose
The purpose of the study is to systematically review the literature of indirect cost of financial distress to understand its scope, measurements, impact size and determinants to synthesis with future research agenda.
Design/methodology/approach
Five-step process of systematic literature review (SLR) as applied by Opoku et al. (2015) is used. SLR extracted 47 studies of indirect cost after applying specified search criteria. Data regarding measurement, impact size and determinants are presented and summarised in specified tables.
Findings
SLR showed that the study of indirect cost in developing countries is a literature gap. It is also found that opportunity loss, operating profit loss, market loss and risk premium are most studied indirect costs using legal definition or ex ante proxy of financial distress. However, future studies are recommended to use both non-linear leverage and ex ante proxy of financial distress. Future studies are also suggested to use the moderation technique while studying the determinants of indirect cost.
Research limitations/implications
Literature selection is based on specific search criteria that can miss some of the other related literature.
Originality/value
The indirect cost of financial distress is more costly and difficult to measure due to its complex concealed effects. A detailed literature of indirect cost is needed to understand the construct that eventually will help to define the future research agenda. To the best of the authors’ knowledge, no SLR of indirect cost is provided yet. Therefore, the outcome of this research will be valuable for both academicians and practitioners.

Abstract
Despite the extensive research on the determinants and consequences of firm growth, research focusing on how the actual process unfolds is still evolving. An important part of firm growth process research is entrepreneurial cognition. The purpose of this chapter is to explore the relationship between entrepreneurial cognition and firm growth intentions. Specifically, we propose a theoretical model of entrepreneurial cognitive interpretation and categorization of market information as it relates to firm growth intentions. Drawing from the strategic cognition literature in general and strategic issue interpretation literature in particular, we propose that entrepreneurs’ interpretation of market information as opportunity or threat, gain or loss, and controllable or uncontrollable influences their firm growth intentions. Furthermore, our theoretical model discusses the condition under which favorable interpretation of market information leads to higher growth intentions by incorporating insights from the Entrepreneurial Orientation (EO) construct. This chapter extends our understanding of firm growth processes by highlighting the important role cognitive interpretation and categorization play in facilitating or hindering entrepreneurial firm growth.

Abstract
Purpose
Property often forms the biggest component of household wealth and assets. Irrespective of landowners’ willingness, the act of compulsory acquisition abruptly ceases the security that this ownership carries. This often induces dissatisfaction among affected landowners over the: loss of “property rights”; loss of commodity, or property; and loss of future opportunities associated with the property. Though there have been attempts in various land acquisition laws and a practice to compensate acquirees for their loss, the dissatisfaction of acquirees has persisted. The persisting resistance of landowners compels deeper insight into the process of compulsory purchase and the compensation mechanism to understand underlying causes for resistance. The purpose of this paper is to investigate the extent of involvement of these different stakeholders, at various stages in the compulsory purchase process, using stakeholder interaction analysis. Results obtained from this research will be helpful in identifying the gaps in the process of compulsory purchase of land for public projects in Australia.
Design/methodology/approach
A survey of ten different stakeholder groups has been conducted to inquire the level of interaction of different stakeholders at various stages of compulsory purchase process. A comparative study was then performed to identify the gaps between the advocated process (suggested in the literature) and the process adopted by stakeholders.
Findings
The results illustrate that: affected landowners seek involvement at the initial stage when the project plan is under preparation and compulsory purchase declaration are not finalised; objectors (from the public) seek opportunities to convey, to the public agency, their views even though the accountability of public agencies towards this stakeholder is nil; and strong interactions are established during negotiation over the compensation amount thus signifying the urge of acquirer and acquirees to avoid monetary losses and time delays.
Originality/value
This research will be useful in identification of pain points in the compulsory purchase process for public projects. This shall help in evolution of fairer mechanism of land acquisition.

Abstract
Purpose
The purpose of this study is to critically analyze the Financial Compensation Funds being accumulated by Islamic Banks of Bangladesh in credit-based transactions. In this connection, due to the evolved liquidity crisis amidst the COVID-19, industry opinions are observed that suggest including the compensations or the donation funds directly into the bank's income account. But the Sharīʿah does not permit it. Such alternative proposals of using compensation or donation fund during crises are scrutinized under Sharīʿah principles to come to a logical conclusion.
Design/methodology/approach
The approach followed in the study is textual and discourse analysis through descriptions of ideal Sharīʿah-compliant methods for handling late payment of credit and comparison with the industry practices.
Findings
It is observed that there are conceptual gaps in the industry as is reflected in the Islamic Banking Guideline of Bangladesh. The funds collected from the debtor due to late payment are named as compensation (Ta‘wīḍ) whereas the nature of the transaction is a donation (Tabarru'). The misconception can lead to various Sharīʿah non-compliant activities later with the funds. The proposals brought out in the industry to use such compensation/donation funds during a crisis are a consequence of this. The proposals of using such funds for banks' purposes in any situation are not supported by Sharīʿah principles and are against the Islamic banking philosophy.
Originality/value
The study is very relevant to the current crisis of COVID-19 in the domestic Islamic Banking Industry and also instrumental for the future guidance to stick to the Sharīʿah principles in managing compensation or donation funds by the Islamic Banks.

Abstract
Purpose
As research emerged in terms of how narcissism, a negative or dark trait, has been found to be constructive in enhancing entrepreneurial behaviour, there are mixed results regarding the significance of narcissism in the field of entrepreneurship. Additionally, this previous research has mostly been conducted on student or nascent entrepreneur samples within developed economies. Therefore, the purpose of this paper is to explore how narcissistic traits of established entrepreneurs in an emerging economy context infuence their entrepreneurial behaviour both positively and negatively.
Design/methodology/approach
Gioia methodology was applied in the qualitative study by means of in-depth interviews, which allowed for the unpacking of narcissistic traits among established entrepreneurs in South Africa. Four themes emerged from the data, and included insights related to entrepreneurial experience influencing behaviour; business growth linked to personal development; opportunity identification versus loss; and identity separation in relation to authentic identity versus an entrepreneurial identity.
Findings
The findings of the paper contribute to creating an understanding of how to hone individual narcissistic traits for positive influences that develop entrepreneurs while also contributing to their business development, opportunity realization and identity. In addition, the findings highlighted a separation between established entrepreneurs’ authentic personality and the inputs that end up resulting in the entrepreneurial personality.
Originality/value
This paper highlights the possibility of narcissism functioning as a business process involved in entrepreneurship rather than a necessary personality trait. An interesting dynamic contributed to what seems to be a constant battle between the authentic identity and the entrepreneur identity, gaining deeper insight surrounding established entrepreneurs’ experiences to survive and, more importantly, thrive as entrepreneurs.

Abstract
Purpose
Inventory accumulation is a major problem for any organization, as it not only occupies the valuable storage space, but it also blocks the company's capital, leaving the owners with less cash to run the company's business. Aggregation of inventory in any organization contributes to inventory carrying cost; it affects labor productivity, increases equipment expenses and creates a loss of opportunity associated with it. Therefore, it is essential for any organization to come up with a solution to deal with the stockpile of inventory.
Design/methodology/approach
This research aims to examine the potential causes of inventory aggregation in an organization. First, the potential factors for the build-up of inventory are identified from survey data collection, such as questionnaire approach and discussion with industry experts, and then weights are assigned to attributes to study the effects for these factors. After the identification of probable causes, they are analyzed through a multi-criterion decision-making (MCDM) approach and the technique for order of preference by similarity to ideal solution (TOPSIS) to prioritize the severity of these causes toward the accumulation of inventory and take corrective actions to prevent their disruptive effect on the business.
Findings
The top three causes identified from the TOPSIS analysis are sales and forecasting error, defects and quality related issues and communication gap between departments. Firstly, we focus on these major contributors and prioritize them using the TOPSIS analysis. Then, we proceed further toward other factors. The main reasons identified for the accumulation of inventory are (1) forecasting error, (2) bulk purchase, (3) data entry error, (4) communication gaps, (5) quality-related issues, (6) product category not traceable and (7) wrong material being procured.
Research limitations/implications
To carry out the data analysis in this research paper, first survey data collection is done. Then, discussions with managers and executives in the particular domain are carried out, and weights are assigned to the attributes and the criteria to study the effects of the identified factors. After that root cause analysis (RCA) is performed to get to the genesis of the problem and to take necessary corrective action, for carrying out this study, a total of seven potential causes were identified and the contribution of these seven causes on five attributes or criteria, i.e. quantity (in tons), holding and carrying cost, effect on labor productivity, loss of opportunity cost and storage space were studied.
Originality/value
This research paper is the author’s original work, and all the analyses carried out are from the discussion with experts in the field and through the in-depth analysis carried out. This research aims to examine the potential causes of the accumulation of inventory in organizations and their contribution toward factors like inventory carrying cost, labor productivity, and opportunity loss and excessive storage space have been analyzed. This research provides great value to the readers in the respective domain.

Abstract
Purpose
The purpose of the present study is to investigate the community’s view of power outages and their effect on sustainable community development. This research has three aims. This project will first investigate how a blackout affects a community’s ability to live sustainably.
Design/methodology/approach
A survey questionnaire was developed that included 22 factors from the literature. The questionnaire was distributed to diversified segments of society from different regions of Pakistan and examined critical factors affecting sustainable community development. A total of 349 (77%) responses were received.
Findings
The study results confirm that power failure negatively affects the sustainable life of a community. This study found that the reduced production of large manufacturing, decrease leisure and comfort, reduced public administrative efficiency, loss of educational opportunities and increased use of traditional energy sources are the most important factors for sustainable community development. Findings also suggest that policymakers and practitioners in public organizations need to ensure that projects are completed in a timely manner to meet growing community needs.
Originality/value
The purpose of this research is to address knowledge gaps related to power outages and sustainable community development. The major impact of power disruptions on communities was previously disregarded in development discourse. Participants in these discussions recognize communities as genuine stakeholders and acknowledge that power outages can have a substantial impact on their economic and social development. However, previous studies have neglected to address this phenomenon.
