Abstract

Purpose

The purpose of this paper is to review a number of recent initiatives to promote sustainable aquaculture development through improvements to education and training capacity, and innovations in the use of eLearning.

Design/methodology/approach

The authors share their experience in these initiatives and demonstrate how e‐learning has been developed in specific cases to better serve the needs of the aquaculture sector, while addressing the pedagogical issues of distance learning and finding the best use of new internet‐based technologies.

Findings

These examples show how to respond to the needs of adult learners who may have a substantially different learner profile to typical campus students and have a more diverse range of needs and background knowledge. Greater focus is needed on defining, enhancing and accrediting knowledge and skills acquired informally and “on the job”, so as to develop more effective formal education interventions.

Practical implications

Adults engaging with job‐related education are not empty vessels requiring to be filled with the correct mix of knowledge and skills by teachers who know all the answers. They are active learners seeking a supportive and enabling structure involving access to appropriate resources, engagement with fellow learners and more expert practitioners, and appropriate challenges and rewards to maximise effort and achievement.

Originality/value

The paper shows that there is substantial social benefit in promoting an innovative and sustainable aquaculture industry that contributes positively to food security and human health. Continued Professional Development involving eLearning and other innovative approaches can make an important contribution throughout the sector.

Abstract

Purpose

The COVID-19 pandemic is known to have affected the logistics and supply chains; however, there is no adequate empirical evidence to prove in which way it has affected the relationship between the stocks related to this field with the corresponding cryptocurrencies. This paper aims to test the dynamic relationship of cryptocurrencies with supply chain and logistics stocks.

Design/methodology/approach

In this paper, the author tests the causal and long-run relationship between logistics and supply chain stocks with the corresponding cryptocurrencies related to these fields, or those that are known to exhibit characteristics that can be utilized by these fields, testing also whether the COVID-19 pandemic affected this relationship. To do so, the author performs the variable-lag causality to test the causal relationship, and examines if this relationship changed due to COVID-19. The author then implements the multifractal detrended cross-correlation analysis to investigate the characteristics of a possible long-run relationship, testing also whether they changed due to COVID-19.

Findings

The results indicate that there is a positive long-run relationship between each logistics and supply chain stocks and the corresponding cryptocurrencies, before and also during COVID-19, but during COVID-19 this relationship becomes weaker, in most cases. Moreover, before COVID-19, the majority of the cases indicate a causal direction from cryptocurrencies to the stocks, while during COVID-19, the causal relationships decrease in multitude, and most cases unveil a causal direction from the stocks to cryptocurrencies.

Originality/value

The causal pattern changed during COVID-19, and the long-run relationship became weaker, showing a change in the dynamics in the relationship between logistics and supply chain stocks with cryptocurrencies.
