The undertaken research investigates the extended unified theory of acceptance and use of technology (UTAUT) model from the perspective of online education in the deadliest period of COVID-19. This research investigates the extended dimensions, for instance, mobile self-efficacy and perceived enjoyment besides traditional elements of the UTAUT model with the relationship of behavioural intention and user behaviour of LMS. Since the COVID-19 led to social isolation (SIS), thus, this study has incorporated SIS as mediating factor and fear of COVID-19 (FOC) as the moderating factor for the considered extended model of UTAUT.

The EU dairy sector has faced new challenges since the main EU enlargement in 2004. This paper investigates spatial raw milk price transmission between Germany, France, the Netherlands, Poland, Lithuania, and Latvia. The study applies the Granger Causality test to analyse the short-term raw milk price movements between the selected markets.

More than half of food waste is generated at the household level, and therefore, it is important to tackle and attempt to solve the problem of consumer food waste. This study aimed to identify factors differentiating high food wasters from low food wasters. A large-scale survey was conducted in Lithuania. A total of 1001 respondents had participated in this survey and were selected using a multi-stage probability sample.

During the COVID-19 crisis, there were many restrictions to transportation. Due to that, a significant disruption in the food supply chain has emerged. The transportation of the fresh food and maintaining the quality, from farm to the table or distributing and then collecting from the warehouses and delivering to the consumer, has become crucial. Technologies and especially IoT, have become the primary tool to fight it. The research objective is to analyze and create new knowledge about digital technologies used to improve and make more effective the food supply chain processes.

The purpose of the article is to assess the optimal ratio of environmental taxes in the context of national security. National security is defined as a complex parameter of indicators of economic, environmental and energy security, sensitive to the impact of environmental taxation, according to the method of Kolmogorov-Gabor. The environmental taxes with the greatest impact on the three identified components of national security have been selected.

This paper suggests that the efficiency of a system (decision-making unit) and its subsystem cannot be properly measured using a two-stage data envelopment analysis (DEA) model either in cooperative or non-cooperative evaluation. Indeed, the existing methods subjectively determine the status of the subsystems in the whole system. The two-stage DEA models, either cooperative game or non-cooperative game, are used to analyze the environmental efficiency.

This paper proposes an integrated approach towards rapid decision-making in the agricultural sector aimed at improvement of its resilience. Methodologically, we seek to devise a framework that is able to take the uncertainty regarding policy preferences into account. Empirically, we focus on the effects of COVID-19 on agriculture.

Each country faces both export and import risks in its trade. The analysis of this research seeks to answer the question about what kind of risks are posed by imports. The purpose of the document is to analyze the purpose of the import and most common risks posed by imports and to assess the trends in imports of Lithuanian agricultural and food products.

The article aims to identify the risk groups arising in foreign trade in the four main groups of processed beverages at a national level. Processed agricultural drinks do not fall into the category of essential food. The article examines four main drink groups: waters (including mineral waters and aerated waters, with additive), beer, wine, and other alcoholic (e.g.,spirits, liqueurs, whiskies, rums, gins, vodkas, etc.) beverages. The case of Lithuania is presented.

Early retirement from farming had been proposed by many of the EU measures. The age structure in the EU currently demands a shift in such an outdated approach, focusing on the treasury experiences of elderly people, which should be utilized by involving them in social and economic activities at the same time. Among the key challenges for rural development policy aiming to increase the quality of life of elder people, next to the traditional help and support measures, is the involvement of the elder generation in economic and social life as well. Therefore, the new EU agricultural policy measures should ensure that funding and institutional incentives support extending the working and active social life of elder farmers.
