Abstract

Purpose

Epidemics and pandemics can result in sudden morbidity and mortality as well as social and economic disruption. However, the humanitarian logistics and supply chain management (HLSCM) field has been mostly focusing on life saving operations after natural disasters such as earthquakes and hurricanes. There is no research within the HLSCM literature neither on the unique properties of vulnerable groups, nor their underlying risk factors or how to mitigate them. The COVID-19 pandemic highlighted the uniqueness of some vulnerable groups and motivated us to conduct a structured literature review to identify research needs in HLSCM with regards to vulnerable populations.

Design/methodology/approach

The authors conduct a systematic review of literature on the intersection of epidemics/pandemics, humanitarian operations and vulnerable populations. They utilize the Scopus database to search for peer-reviewed journal articles published in English. Our search results in 366 articles which we reduced to 139 after filtering.

Findings

There is no research within the HLSCM literature on the unique properties of various vulnerable populations. The authors show that HLSCM scholars can contribute to literature by investigating operational and logistical challenges of serving vulnerable populations through multi-disciplinary research, research on the intersection of public health and supply chain management, research on the intersection of ethics and operations management, and research on cross-sectoral partnerships.

Research limitations/implications

The authors’ work is limited to peer-reviewed journal articles published in English. They did not include books, conference proceedings and think-tank or NGO reports. However, the authors do recognize that these sources can be very valuable.

Originality/value

To best of authors’ knowledge, this is the first study to review the literature on vulnerable populations under the threat of epidemics and pandemics.

Abstract

Purpose

In this research, the authors apply artificial neural networks (ANNs) to uncover non-linear relationships among factors that influence the productivity of ragpickers in the Indian context.

Design/methodology/approach

A broad long-term action research program provides a means to shape the research question and posit relevant factors, whereas ANNs capture the true underlying non-linear relationships. ANN models the relationships between four independent variables and three forms of waste value chains without assuming any distributional forms. The authors apply bootstrapping in conjunction with ANNs.

Findings

The authors identify four elements that influence ragpickers’ productivity: receptiveness to non-governmental organizations, literacy, the deployment of proper equipment/technology and group size.

Research limitations/implications

This study provides a unique way to analyze bottom of the pyramid (BoP) operations via ANNs.

Social implications

This study provides a road map to help ragpickers in India raise incomes while simultaneously improving recycling rates.

Originality/value

This research is grounded in the stakeholder resource-based view and the network–individual–resource model. It generalizes these theories to the informal waste value chain at BoP communities.

Abstract

Purpose

Humanitarian logistics has for a long time been argued to be a new discipline. Now that even the Journal of Humanitarian Logistics and Supply Chain Management (JHLSCM) has existed over a decade, it is time to take a closer look at its evolution. This article provides some understanding for the developments of humanitarian logistics over the past decade, reveals current trends and discovers what lies behind the curtains in the humanitarian logistics and supply chain management discipline.

Design/methodology/approach

This article brings in developments and discussions in humanitarian logistics practice into the research domain.

Findings

The article conveys the concerns of humanitarian logistics practitioners to research. These include the backlash from the COVID-19 pandemic as a prime current concern, and also other longer-term issues and developments.

Research limitations/implications

The themes identified in the article can be used to inform a research agenda in humanitarian logistics and supply chain management. The article revisits a framework of global events and their cascading impacts to include non-linearities and multiple disruptions from evolutionary disasters such as the COVID-19 pandemic.

Practical implications

The article argues for more collaborative and co-designed research to increase the relevance and impact of humanitarian logistics.

Social implications

Wider societal views are brought into the area of humanitarian logistics.

Originality/value

The article highlights the gaps that remain in humanitarian logistics and supply chain management research.

Abstract

Purpose

Modern slavery is a humanitarian problem that affects global supply chains. Given the increasing pressures from legislature, consumers and investors, firms have a growing interest in eliminating forced labor and modern slavery from their supply chains. However, the impact of modern slavery on firm performance has not been shown before. This paper aims to investigate the impact of modern slavery allegations on companies’ operational performance. It also looks at the role of corporate social responsibility (CSR) efforts with respect to modern slavery.

Design/methodology/approach

The authors collect news articles on modern slavery in the global supply chains. The authors use an event study and use a robust matching method to measure the operational impact of modern slavery allegations. The authors also analyze the effects of media coverage and CSR practices on the relationship between allegations and firm performance.

Findings

The results show that modern slavery allegations do have a negative impact on performance, but this impact does not last long. The authors also show that strong CSR practices help firms mitigate the negative effect of these allegations.

Research limitations/implications

Because the issue is hidden, as a result limited data, the research results may lack generalizability. Therefore, researchers are encouraged to retest the proposed propositions in the future.

Practical implications

The paper includes implications for the development of socially responsible supply chains and financial impact.

Originality/value

This paper presents the first empirical research investigating the impact of modern slavery allegations on companies’ operational performance.

Abstract

Purpose

The Covid-19 pandemic exposed the fragility of global supply chains. Attempts to deepen our understanding of the effects of the pandemic on global supply chains mostly offer anecdotal evidences and lack theory grounded research. The purpose of this paper is to develop a conceptual framework to help explain supply chain disruption management.

Design/methodology/approach

This is a conceptual paper and uses a theory building approach. It develops a conceptual framework adapted from coping theory in psychology to explain supply chain disruption management. To refine the framework, the authors independently reviewed extant supply chain disruption management literature. The authors then studied the frameworks on stress theory in psychology. Following the review of both streams of literatures, the authors developed an initial draft of the conceptual model. This draft was then iteratively refined through extensive discussions among the authors.

Findings

Coping theory can help revise supply chain disruption management with an alternative lens that has not been applied before in this domain. The proposed conceptual framework is generic and can be applied to disruption management strategies for any organization in any industry.

Originality/value

The conceptual framework proposed in this paper offers a new theoretical lens to supply chain disruption management discourse. It contributes to the operational understanding of supply chain disruption management.

Abstract

Purpose

The purpose of this paper is to examine when and how organizations create agility, adaptability, and alignment as distinct supply chain properties to gain sustainable competitive advantage.

Design/methodology/approach

The current study utilizes the resource-based view (RBV) under the moderating effect of top management commitment (TMC). To test the research hypotheses, the authors gathered 351 usable responses using a pre-tested questionnaire.

Findings

The statistical analyses suggest that information sharing and supply chain connectivity resources influence supply chain visibility capability, which, under the moderating effect of TMC, enhance supply chain agility, adaptability, and alignment (SCAAA).

Originality/value

The contribution lies in: providing a holistic study of the antecedents of agility, adaptability, and alignment; investigating the moderating role of TMC on SCAAA; following the RBV and addressing calls for investigating the role of resources in supply chain management, and for empirical studies with implications for supply chain design.

Abstract

Purpose

An unprecedented scale of human migration has lead humanitarians to view camps as long-term settlements rather than temporary holding facilities. The purpose of this paper is to increase the understanding of and identify challenges with this proposed new approach to camp design.

Design/methodology/approach

Based on the camp design literature, the authors developed an interview guide and checklist for data collection. A multi-site case study and within- and cross-case analysis was then conducted.

Findings

The findings suggest that the proposed new approach is implemented only to a limited extent, and mostly in a stepwise manner. As camps mature, there is a shift toward the new approach, but most camps are established using the traditional top-down, temporary, and isolated approach.

Research limitations/implications

The findings are based on four camps in four different countries and do not provide an exhaustive global coverage.

Practical implications

The insights the authors derived and the challenges identified from the empirical evidence can be used to better plan future camps.

Social implications

The results can support improvements in camp design, thus alleviating suffering for both refugees and host communities, particularly in developing countries. In particular, the trade-off between a permanent solution and the temporary must be accounted for.

Originality/value

The study contributes to the literature by developing and proposing a conceptual framework to camp design. The cross-case analysis provides an initial understanding and categorization of challenges with implementing the new approach. It also suggests an evolutionary perspective of camp design.

– The purpose of this paper is to investigate the changes in perceptions and actions taken on post-disaster entrepreneurial opportunities.

Abstract

Purpose

The purpose of this paper is to investigate the changes in perceptions and actions taken on post-disaster entrepreneurial opportunities.

Design/methodology/approach

Utilizing worldwide data on natural disasters (EMDAT) and entrepreneurial perceptions (Global Entrepreneurship Monitor (GEM)), the authors apply analysis of covariance to compare entrepreneurial opportunity perceptions and actions before and after a disaster took place.

Findings

The study found that natural disasters have a significant and positive impact on entrepreneurial opportunity perceptions and actions but not on perceptions of self-efficacy, fear of failure and entrepreneurial intentions.

Research limitations implications

One limitation of the study is the use of the secondary data. While the GEM data as well as the EMDAT data are country specific, disasters usually have a direct impact on a region of a country rather than affecting the whole country’s behavior.

Practical implications

The results hold important policy implications. The fact that disasters increase entrepreneurial action implies that local government institutions should include entrepreneurial action as part of the post-disaster recovery process. By providing assistance and access to resources, government institutions could further increase entrepreneurial action and could increase the number of opportunities perceived by individuals which would lead to new and innovative businesses, in addition to the rebuilding of pre-existing firms.

Originality/value

Natural disasters are frequently considered to be the cause of small business failures or an obstacle to their performance, while simultaneously thought to be a vital component of post-disaster reconstruction. To date, few researchers have attempted to understand the impact of these events on entrepreneurial tendencies, behaviors and activities, even though the authors barely understand how they could serve as a source of entrepreneurial opportunity and innovation. This research is one of the first attempts to shed some light into this interesting and important phenomenon.
