The continual onset of natural and manmade disasters propels the humanitarian supply chain (HSC) efforts (by organizations, groups and individuals) to always be on a stand-by mode with more and more sustainable solutions. Despite all the sincere and coordinated efforts from all the humanitarian agents and bodies, the likely sustainable outputs are hampered by certain barriers (impediments) which exist at different levels of the HSCs. A better understanding of such barriers and their mutual relationship is deemed helpful in improving the outcomes of humanitarian efforts. Thus, the purpose of this paper is to explore, refine, establish and classify these barriers which thwart the sustainable efforts of the HSCs individually as well as collectively.

An extensive literature review is conducted to identify these barriers which were followed by soliciting the experts’ inputs to update, refine and retain the contextually relevant ones. The opinions about the nine identified and refined barriers are taken from eight experts based in the Northern India who are having at least five years of experience in humanitarian operations. Fuzzy interpretive structural modeling (FISM) is used to examine and establish a hierarchical relationship among these barriers, whereas fuzzy Matrice d’impacts croisés multiplication appliquée á un classment analysis is carried out to further classify these barriers into dependent, autonomous, linkage and dependent barriers.

The analysis led to the formation of a FISM model where the operational challenges affecting the performance occupy the topmost position in the hierarchy. The results reveal that inconsistent motives, coordination and communication and operational challenges affecting the performance are the dependent, poor strategic planning, capacity-related challenges and poor performance measurement system are the autonomous, and financial challenges, locational challenges and lack of proper awareness are the independent barriers.

The focus of the researchers was to study and examine these barriers to sustainable HSCs with special reference to the epidemics and pandemics (especially COVID-19), and it sheds light particularly arising during and post disaster phases.

The structural model contributed by this study is expected to be meaningful for practitioners besides enriching the body of literature. In the context of pandemics, it distinguishes itself from the other available frameworks.

As this research has been carried out in the context of the novel COVID-19, the framework is expected to assist policymakers in comprehending the issues impeding the sustainability of noble humanitarian efforts. Thus, ultimately it is expected to contribute to the ultimate cause of society at large.

This research endeavor distinguishes itself from the other accessible published resources in terms of the specific context, the methodological approach and the nature of respondents. This paper concludes with the practical implications and directions for future research.

The purpose of this paper is twofold. First, to examine the influence of two dimensions of entrepreneurial competencies, namely, strategic competency and ethical competency on the growth of small and medium enterprises (SMEs); and second, to explore the role of network competence as a mediator among these understudied variables.

The data for this study were collected from wholesale and retail-based SMEs in Malaysia through a standard structured questionnaire. PLS–SEM approach was utilised to analyse the data.

Although the findings did not reveal a direct effect of strategic and ethical competencies of entrepreneurs on SMEs’ growth, these competences, however, were found to be influential in driving their growth when network competence was used as a mediator.

The existence of a mediation effect between strategic and ethical competencies and SMEs’ growth via network competence has provided insights which add new knowledge to the extant entrepreneurship and SMEs’ performance literature.

Net zero energy buildings (NZEBs) are essential for reducing the environmental consequences of the construction industry. However, its uptake within the industry has been limited, and the inherent barriers remain not fully explored especially in developing countries. This paper aims to examine the critical barriers that hinder the implementation of NZEBs in the construction sector of developing economies like Ghana.

Quantitative data were collected from 80 construction professionals in the Ghanaian construction industry (GCI) using online survey questionnaires. The data set underwent analysis following a four-level analytical protocol comprising reliability test analysis, mean score ranking, exploratory factor analysis and fuzzy synthetic evaluation.

Market readiness barriers were considered the most crucial barriers to the implementation of NZEBs in the GCI with an index of 4.023. This was followed by awareness and policy barriers with an index of 4.007. Finally, resistance to change, then cost and capacity barriers were ranked third and fourth, based on their indices of 3.763 and 3.615, respectively.

The results of this research shed light on a relatively unexplored area within the construction sector, particularly in a developing country like Ghana. The findings of this study will provide valuable information to support policy reviews and formulation and buttress the drive towards sustainability and achieving NZEBs.
