Purpose: The aim of this study is to identify the way in which research on new business models in agri-food sector has been developed, in order to identify the main lines of work followed and determine a future research agenda in this field.Design/methodology/approach: A systematic review of the literature is carried out, by applying the PRISMA method to identify and classify the main articles published on agri-food business models in journals included in the Web of Science Core Collection database.Findings: The systematic literature review has identified three main forms of business models in the agri-food sector: sustainable business models, technology-based business models and cooperative business models. The three types of new business models are complementary and can sometimes be adopted together. The identification of these types of business models and the variants included in each of them is a valid starting point for new developments in this field.Research limitations/implications: The limitations of this study are those typical of any literature review and derived from the methodology used. The establishment of criteria relating to time, language, type of publication or database chosen means that this review may have left out relevant studies in this field of research. It is therefore recommended that new reviews be carried out with different criteria in the coming years in order to supplement the results obtained in this study.Originality/value: Some research gaps were identified that should be further explored in the future. First, the relationship between digitisation and technological innovation in agri-food business models and the level of implementation of sustainable objectives in these business models has not been researched thoroughly. In addition, and despite the fact that the crisis caused by the COVID-19 pandemic has boosted innovation in agri-food business models, the authors have detected a lack of papers focused on solving problems arising from the shortage of raw materials or labour, possible energy crises or external dependence on local markets when it comes to meeting demand. The war in Ukraine has demonstrated the limitations of international markets, mainly the European market, when it comes to dealing with problems arising from this type of crisis.

Thermal comfort in educational buildings affects not only the well-being of students but also their academic performance. Over time, various methods have been developed to assess it. However, none of them takes into account the adaptation of students of different ages, which is an important issue. In recent years, the study of thermal comfort has become very important due to energy-saving measures and ventilation protocols to combat the spread of the SARS-CoV-2 coronavirus. Therefore, it is necessary to gather all the information to guide future research. Thus, this paper presents a comprehensive review of field studies on thermal comfort in classrooms at different educational levels. The focus is on those conducted during the global pandemic of COVID-19. It has been observed that students from climates with a higher degree of variation have shown a better adaptation. Children also tended to feel less affected by changing temperatures. High school and university students showed a greater range of dissatisfaction with heat than with cold. The adaptive approach is more suitable for recognising the comfort needs of all age groups. However, by using this approach together with the Fanger method, more reliable results have been reported. In most of the studies, comfort levels were found to be lower than those indicated by the standards, highlighting the need for guidelines adapted to the thermal comfort conditions of all students. Finally, the various natural ventilation measures to avoid COVID-19 infection have led to a decrease in comfort levels, especially in winter.

Partnerships between businesses and non-governmental organizations (NGOs) have become widely adopted mechanisms for collaboration in addressing complex social issues, the aim being to take advantage of the two types of organizational rationale to generate mutual value. Many such alliances have proved to be unsuccessful, however. To assist managers improve the likelihood of success of their collaborative relationships, the authors propose a success model of business-NGO partnering processes based on Relationship Marketing Theory. They also analyse the theoretical bases of the model's hypotheses through a meta-analytical study of the existing literature
