Abstract

Purpose

During a crisis situation, a poultry supply chain is faced with high variations on fresh chicken meat demand and has therefore to simultaneously manage excessive shelf-life stocks (in case of falling demand) and external purchases due to inventory shortages. In this case, the production plan is often established according to non-accurate sale forecasts which require ongoing adjustment. The paper aims to discuss these issues.

Design/methodology/approach

By using system dynamics, the paper developed a model of the French poultry supply chain during a given avian influenza crisis period. The authors compared exponential smoothing forecasting method to a word-of-mouth diffusion model which makes sense in a sanitary crisis context.

Findings

An interesting result shows a complex relationship between the sanitary risk (which increases according to the slaughtered chicken's volume and storage time) and the additional external purchases (in case of low production generated by an insufficient forecasting launched 40 days before customer orders).

Research limitations/implications

Additional costs which vary over time are required for further assumptions testing.

Practical implications

The paper proposes to use a forecasting model which is not currently used by the professionals during a sanitary crisis period. This model is able to simulate an internal dissemination of a call for boycott of meat products (cf. negative word-of-mouth spread).

Originality/value

The problem is how to maintain a less risky but significant buffer size to respond to a supply chain coping with both changes in customers’ demand and instability in production capacity.

Abstract

Purpose

The purpose of this paper is to study the behaviour of a food supply chain possessing two originalities, i.e. a singular structure (40‐day upstream push and 24‐hour downstream pull) and one that suffers from simultaneous fluctuations in raw material supply capacities (due to epizooty) and customer demand (due to customer anxieties and fears) caused by a sanitary crisis.

Design/methodology/approach

A simulation model based on the system dynamics principles of Forrester is developed and applied to the French chicken meat supply chain suffering an Avian Influenza crisis.

Findings

This model first enables one us to study the regulation mechanisms of the chain that will improve understanding of the supply chain behaviour under environmental perturbations. A what‐if analysis is then implemented to examine the supply chain stability and the influence of flexibility adjustment times, inventory coverage time, slaughtered chicken buffer size and smoothing policies on the supply chain performance in different crisis fluctuation rate scenarios in order to propose necessary logistic policy enhancements.

Research limitations/implications

This work will improve one's knowledge about the buffer inventory problem and the global stability of this multi‐echelon push‐pull supply chain.

Practical implications

The model can be used as a decision system support which aims to minimise the additional costs due to stock level increases as demand decreases as well as exceptional external purchasing sparked by the lack of available products when there is a sudden hike in demand. The research can help decision‐makers of fresh food push‐pull supply chains when they are facing such crises by using both cybernetic representation and computer simulation.

Originality/value

This study deals with a specific food supply chain within the context of a sanitary crisis. A system dynamics model is presented for studying the behaviour of the entire food supply chain threatened by high uncertainties in the supply capacity as well as in customer demand.

Abstract

In the wake of the COVID-19 health crisis, destinations are facing the challenging task of reopening their borders while keeping resident population safe. Destination communities help to flatten the infection curve while tourists contribute to spread the virus. This chapter explores the impacts of a health crisis on stakeholders' emotional solidarity and support for tourism. Twenty-six semi-structured interviews were conducted with different stakeholders. Findings show that informants who perceive socioeconomic tourism benefits are likely to support it in exchange for appropriate health measures. Others affected sociopsychologically by the pandemic feel negative emotional solidarity toward foreign tourists. Thus, delineating the role of a health crisis becomes a crucial research question that can contribute to academic understanding of support for tourism. As uncertainty over border reopening currently affects 24% countries worldwide, these findings can be relevant to policymakers.

Abstract

Purpose

This study aims to confirm the expected impact of coronavirus (COVID-19) related to perceived travel risk on the likelihood of tourists to visit a destination. It then aims at identifying the key predictors of perceived travel risk in the aftermath of the COVID-19 pandemic. A theoretically grounded framework is proposed which can be further improved to understand and predict international travel behaviours within the context of global pandemics.

Design/methodology/approach

A mixed-methods design is adopted. In the first phase referred to as Study 1, a cross-sectional design is used based on a sample of 217 international outgoing tourists surveyed at the Mauritian International Airport and data is analysed using hierarchical regression. In Phase 2, referred to as Study 2, a purposive sample of tourists around the world are interviewed and data is analysed using the thematic analysis technique.

Findings

The results show that amongst those tourists who are willing to travel in the aftermath of the COVID-19 crisis, the related perceived risk is likely to influence their travelling intention. Several key predictors of perceived travel risks are uncovered, those are categorised as COVID-19 status; transportation services; national sanitary measures; health-care services; accommodation services; ecotourism facilities. Moreover, the potential effects of those factors on perceived COVID-19 related travel risk are likely to be moderated by the trustworthiness of the information.

Practical implications

The implications of the study are important for researchers and policymakers to better understand and predict travellers’ behaviour in times of pandemics. These implications are also important to tourism marketers and transport and hospitality service providers to more effectively manage and mitigate the effect of such events.

Originality/value

The study provides an original comprehensive model grounded in the social cognitive theory and protection motivation theory to understand the predictors of perceived travel risks in relation to COVID-19 at a destination.

Abstract

Purpose

This study is in line with the debate concerning the compatibility between the qualitative and quantitative food production objectives. The purpose of this paper is to identify the causal relationship that may exist between public food safety regulations (specifically, the maximum authorised levels of chemical or microbiological contaminants), and the expected price in the spot markets (wholesale markets, for example).

Design/methodology/approach

The authors propose a theoretical industrial economic model that identifies the causal link which may exist between public food safety regulations (e.g. the maximum authorised levels of chemical or microbiological contaminants), the expected price in domestic markets, and the rate of exclusion of local producers. This general model allows one to characterize the price formation process in markets subject to maximum residue level constraints by focusing on the role of the official inspection systems established by public authorities.

Findings

The authors show how strengthening official controls does not systematically impact negatively on producers’ participation and does not always decrease supply. Moreover, the authors show that reinforcing the maximum permitted contamination thresholds is not always sufficient for ensuring consumer health.

Originality/value

The originality of the model is that it shows how all variables (economic and sanitary variables) interact in the formation of agricultural prices and determine the final size of the productive system (number of active producers). The characterisation of the market price as a function of producers’ investment efforts and of the level of official control reliability allows one to determine both the total supply and the proportion of this supply that is contaminated (i.e. does not comply with the maximum threshold of contamination).

Abstract

Purpose

In a context of critical transition such as the COVID-19 pandemic, moral semantics take a prominent role as a form of self-description of society. However, they are not usually observed, but rather assumed as self-evident and necessarily “good.” The purpose of the article is to summarize the theory of morality from the social systems' perspective and illustrate with concrete examples the polemogenous nature of moral communication.

Design/methodology/approach

This article presents an analysis of the role of morality in the context of the COVID-19 pandemic, from the perspective of Niklas Luhmann’s social systems theory. Applying the method of second-order observation, it describes three cases of moral semantics disseminated via mass media and social media, and it examines their connection with the structural situation of subsystems of society during the pandemic crisis (particularly healthcare, politics and science).

Findings

Second-order observation of moral communication demonstrates to be fruitful to describe the conditions and consequences in which moralization of communication occurs, particularly in a situation of critical transition around the healthcare crisis. The three examples examined, namely, the hero semantics directed to healthcare workers, the semantics of indiscipline and the controversies around pseudo-sciences and conspiracy theories, show how they are based on social attribution of esteem and disesteem, how they try to answer to troublesome situations and contradictions that seem difficult to cope, and how they are close related to the emergence of conflicts, even when they seem positive oriented and well intentioned.

Originality/value

This paper is an attempt to test the usefulness of Luhmann's theory of society to understand the ongoing COVID-19 crisis and particularly the role of moral communication in concrete examples.

Abstract

Purpose

This paper aims to present reflections on the COVID-19 pandemic impacts in the search for the targets of Sustainable Development Goal 8 (SDG 8) disseminated by the United Nations. These reflections are made considering the Brazilian scenario.

Design/methodology/approach

As this paper is a viewpoint, several information presented here are based on authors’ opinion. However, to enhance the information basis and present examples, a bibliographic research was also conducted.

Findings

Analyzing the targets of SDG 8 and the probable crisis in the Brazilian economy as a consequence of the pandemic, the authors believe that this crisis will impact the achievement of these targets.

Practical implications

The reflections presented here can contribute with the debates about the search for decent work in Brazil. It is worth to remember that the development of actions aligned with SDG 8 targets generates more than only economic gains, as these contribute for building a more just, egalitarian and inclusive society.

Originality/value

This viewpoint calls attention to issues that demand urgent public policies; otherwise, these issues can generate losses to an entire generation of Brazilians.

Abstract

Purpose

This paper aims to integrate research on KM with the effectuation approach. This paper will add to the understanding of effectuation as a KM tool in the context of social entrepreneurial networks. Although researchers agree that the lack of resources is a structural point for the context of social entrepreneurship and that knowledge is crucial in social entrepreneurship, only few studies deal with trying to understand how resources and knowledge are obtained, transformed and managed. An effectual approach seems to be particularly appropriate to work on this subject.

Design/methodology/approach

A literature review leads to a theoretical model that is tested in a single-case study of a French entrepreneurial project.

Findings

The empirical study not only shows the legitimacy of using an effectual approach but also puts forward three concepts that enable a better understanding of the access to resources and knowledge and their use in the context of social entrepreneurship. This study contributes to the knowledge management literature in identifying the process of gathering and sharing external resources and knowledge through an effectual process led by the entrepreneur and by the network.

Research limitations/implications

The results complement the extant KM literature on the following points: identify the cumulative and absorptive process of knowledge from the network, contributing to the question of KM for growth and corporate entrepreneurship; answer to the claim from Durst and Runar Edvardsson (2012) to develop a greater understanding of knowledge identification, storage and utilization in small businesses; add to the topics of knowledge sharing, knowledge transfer and knowledge creation; and show that stages of creating, identifying, sharing and absorbing knowledge from/with the network are embedded in an effectual approach.

Practical implications

The lack of resources should not lead the entrepreneur to a dead end, but rather invite him/her to better raise following questions: Who can help me to get the missing resource? How could I develop the project without these resources and knowledge? The entrepreneur is invited to search more flexibility in the making of the project, and to seek more support from the network. A second important implication is a guideline that can be followed by business incubators to give better advice and guidance to social entrepreneurs.

Originality/value

The paper links effectuation, KM and social entrepreneurship literatures. The identification of the role of the network in knowledge creation, identification and sharing is valuable for both researchers and practitioners.

Abstract

Purpose

Customers might become concerned about getting contaminated and adapt their behavior accordingly, which is of critical concern for service managers. The purpose of this paper is threefold. First, this paper synthesizes the extant body of research within psychology and marketing into an integrative framework that helps understand the current state of knowledge on contamination. Second, this review summarizes evidence-based managerial recommendations on how to deal with customers' contamination concerns. Third, this paper provides guidance for future research by proposing several ways in which those concerns might influence service management.

Design/methodology/approach

This paper conducts an integrative literature review of over 30 years of psychology and marketing research on contamination concerns.

Findings

The paper reviews physical and metaphysical contagion models, the situational cues that may activate customers' contamination concerns, the psychological mechanisms that underlie the relationship between contamination and customer outcomes and the individual characteristics that influence customer sensitivity to contamination cues. Moreover, this review identifies actions that service managers can take to prevent customers' contamination concerns. Finally, still much has to be learned about how organizations should deal with fear of contamination by the time a next pandemic breaks out.

Originality/value

This paper develops an integrative framework that serves as a structured knowledge map onto the contamination phenomenon and paves the way for future service research.
