Abstract

Purpose

Recent earthquake-induced liquefaction events and associated losses have increased researchers’ interest into liquefaction risk reduction interventions. To the best of the authors’ knowledge, there was no scholarly literature related to an economic appraisal of these risk reduction interventions. The purpose of this paper is to investigate the issues in applying cost–benefit analysis (CBA) principles to the evaluation of technical mitigations to reduce earthquake-induced liquefaction risk.

Design/methodology/approach

CBA has been substantially used for risk mitigation option appraisal for a number of hazard threats. Previous literature in the form of systematic reviews, individual research and case studies, together with liquefaction risk and loss modelling literature, was used to develop a theoretical model of CBA for earthquake-induced liquefaction mitigation interventions. The model was tested using a scenario in a two-day workshop.

Findings

Because liquefaction risk reduction techniques are relatively new, there is limited damage modelling and cost data available for use within CBAs. As such end users need to make significant assumptions when linking the results of technical investigations of damage to built-asset performance and probabilistic loss modelling resulting in many potential interventions being not cost-effective for low-impact disasters. This study questions whether a probabilistic approach should really be applied to localised rapid onset events like liquefaction, arguing that a deterministic approach for localised knowledge and context would be a better base for the cost-effectiveness mitigation interventions.

Originality/value

This paper makes an original contribution to literature through a critical review of CBA approaches applied to disaster mitigation interventions. Further, this paper identifies challenges and limitations of applying probabilistic based CBA models to localised rapid onset disaster events where human losses are minimal and historic data is sparse; challenging researchers to develop new deterministic based approaches that use localised knowledge and context to evaluate the cost-effectiveness of mitigation interventions.

Abstract

Purpose

The purpose of this paper is to estimate the locational marginal price (LMP) at each distributed generation (DG) bus based on DG unit contribution in loss reduction. This LMP value can be used by distribution company (DISCO) to control private DG owners and operate network optimally in terms of active power loss.

Design/methodology/approach

This paper proposes proportional nucleolus game theory (PNGT)-based iterative method to compute LMP at each DG unit. In this algorithm, PNGT has been used to identify the share of each DG unit in loss reduction. New mathematical modeling has been incorporated in the proposed algorithm to compute incentives being given to each DG owner.

Findings

The findings of this paper are that the LMP and reactive power price values for each DG unit were computed by the proposed method for the first time. Network can be operated with less loss and zero DISCO’s extra benefit, which is essential in deregulated environment. Fair competition has been maintained among private DG owners using the proposed method.

Originality/value

PNGT has been used for the first time for computation of LMP in distribution system based on loss reduction. Incentives to each DG unit has have been computed based on financial savings of DISCO due to loss reduction. Share of active and reactive power generation of each DG unit on change in active power loss of network due to that DG unit has been computed with new mathematical modeling. The proposed method provides LMP value to each DG unit in such a way that the network will be operated with less loss.

Abstract

Purpose

The purpose of this paper is to find solutions to improve the red meat sector in an emerging economy, Turkey, from the circular economy point of view, and taking sustainability approach. The need for circular management within the red meat sector in Turkey is emphasized by using Grey method. As theoretical contribution of this study, the investigation of the causes of losses at the slaughter stages of the red meat supply chain leads to proposals for sustainable and circular solutions.

Design/methodology/approach

Grey method is used to predict the number of slaughtered cattle and the amount of bone and blood waste in the slaughtering process between 2018 and 2020.

Findings

It is revealed that according to Grey prediction calculations, although the amount of slaughtered cattle, bone and blood waste seem have decreased between 2018 and 2020, there are still significant losses in Turkish red meat sector. For bone waste, this is expected to be 56,581,200 kg in 2018, 48,235,840 kg in 2019 and 41,121,380 kg in 2020. For blood waste, it is expected to be 24,754,275 kg in 2018, 21,103,180 kg in 2019 and 17,990,604 kg in 2020.

Social implications

The proposed model in the study will contribute on sector revitalization, increase in product safety, quality and hygiene, development in the management of training and education centers for farmers/labors and increase in employment.

Originality/value

This paper represents policymakers with a proposal for triple bottom line (TBL) based circular and central slaughterhouse model, based on TBL, which brings social, economic and environmental benefits for the red meat sector in Turkey.

Abstract

Purpose

This paper aims to examine characteristics that contribute to leaders' emergence and development as social advocates in their organizations and communities.

Design/methodology/approach

Building on theories of social problems, influence, and impression management, this paper examines how advocacy is affected by needs and situational conditions. Advocacy is the act of supporting an idea, need, person, or group. Advocates use cognitive, emotional, and behavioral strategies to influence attitudes, behaviors, and/or decisions for the benefit of individuals or to promote organizational change and/or social welfare. Social advocacy occurs within organizations in the form of corporate social responsibility, and it occurs within communities in the form of social entrepreneurship.

Findings

This theoretical paper argues that motivation of leaders of social ventures is a function of their conviction, self‐confidence, and extroversion. Advocates' beliefs about people are likely to shape their advocacy strategies, in particular, their beliefs about whether people are likely to change their attitudes and behavior, are sensitive to possible losses and gain, and respond to information about the probabilities and outcomes of actions and events. Advocate's resilience and transformational abilities (communications and political skills, knowledge of change management, and learning orientation) are predicted to influence their success.

Originality/value

The paper discusses directions for management development research and practice to promote involvement in social ventures.

Abstract

Purpose

The use of contingent knowledge workers may be an efficient means of investing in an organization's intellectual capital. However, exposing contingent workers to private, key competitive knowledge is considered risky. A study was undertaken to collect the costs, benefits and losses experienced by organizations that had contracted contingent knowledge workers to develop intellectual capital.

Design/methodology/approach

A purposive cross‐section of senior managers of knowledge‐intensive organizations were interviewed regarding the tangible benefits, costs, perceived risks, and experienced losses from contingent knowledge worker arrangements. The constant comparison method of analysis was used.

Findings

The data revealed perceived increases in flexibility, expertise, creative stimuli, and knowledge bank development. These benefits were believed to have bottom‐line impact through product and process improvements and innovations, and operational efficiencies. The managers did not perceive much risk or experience material losses as a result of the contingent knowledge worker arrangements.

Research limitations/implications

These findings are based on interviews with a small group of organizations. Although not generalizable, they present an interesting contrast to previous researchers’ conclusions regarding the use of contingent knowledge workers. Further empirical work is needed to test the degree to which this study's findings can be generalized.

Practical implications

Contrary to recent literature, this study suggests that contracting contingent knowledge workers to develop in‐house intellectual capital is worth the risk.

Originality/value

The study presents a divergent viewpoint on the contracting of contingent knowledge workers. It also initiates research on rational evaluation of investments in intellectual capital, which constitutes an important contribution to the area of knowledge management. It also contributes to the ongoing research on intellectual capital valuation.

Abstract

Purpose

This research studies the impact of introducing distributed generators (DGs) into a distribution network. The aim of this paper is to optimally site DGs based on economic, environmental and reliability indices are presented.

Design/methodology/approach

The considered network was modelled by using the network’s line parameters and capacity of the load bus with the help of Power System Analysis Toolbox. The location of the DG is based on voltage stability index and power loss reduction index. The DG energy sources considered are the diesel generator, solar photo-voltaic (PV) and wind generator, and the objectives were to minimize cumulative cost while maximizing reliability of the network. The Advanced Interactive Multidimensional Modelling System was used for the mathematical modelling.

Findings

The obtained results in the cases of introducing renewable energy into a network improves network performance. The benefits of renewable energy on the distribution network measured in terms of electricity production cost, gas emission cost, fuel cost and value of energy not supplied were positive. The research also showed that the total benefit of renewable energy reduces as the price of the renewable generators increases.

Originality/value

This paper introduces a new approach to determining the optimal location of DG for reducing line losses and improved voltage profile. A new cost modelling function based on external grid power transfer cost, technical losses and cost because of the various energies source is also introduced.

Abstract

Given the continuing growth in both the complexity and severity of cyber risk, a fundamental rethink of cyber risk management has become an issue of paramount importance, particularly as insurance firms are now providing both cyber risk management services and cyber risk insurance coverage. In this study, we set out to provide analyses of the prevailing cyber risk levels in various industries using the “Chronology of Data Breaches” database and then go on to assess the overall benefits of cyber risk insurance coverage. Our results reveal that compared to other industries, insurance firms exhibit superior cyber risk management. Regardless of internal and external cyber risk, insurance companies retain the lowest cyber losses. We further provide evidence to show that cyber risk insurance policies alone cannot effectively cover the potentially extreme cyber risk losses for most industries. However, the situation can be improved by implementing cyber risk management services provided by insurance firms. Insurance firms may need to provide an efficient cyber risk management system to lower the frequency and severity of extreme events.
