Over the years, the impact of the business cycle on firm strategy has been neglected in the area of strategic management and remains one of the most important but least developed research streams in management scholarship. Studies in this area are scattered across time and domains, therefore, there is a need to consolidate this fragmented literature to provide a comprehensive review and thus avenues for further research. This study aims to address this gap.

In this study, the systematic literature review (SLR) method is used to select and examine research articles in the area of firm responses and decisions during recession. This SLR examines 127 studies and carries out a thematic synthesis of the literature.

Based on the SLR and thematic synthesis of the literature, the themes identified in this study include – severity of recession impact (Theme 1); firm specific characteristics (Theme 2); resource adjustment activities (Theme 3); and firm performance (Theme 4), based on these themes and analysis this paper maps and proposes various relationships and linkages in this research domain that can be explored further for the development of scholarship in this field of study.

This paper fulfills the need for a systematic review of the extant literature on firms’ responses during recession. The study synthesizes literature and carries out a thematic analysis from 1980 till the period February 2024 to provide directions to advance this domain of literature.

The COVID-19 pandemic has caused significant mortality and morbidity worldwide. However, the role of dietary patterns as a potential risk factor for COVID-19 has not been well established, especially in studies with large samples. Therefore, this study aims to identify and evaluate the association between major dietary patterns and COVID-19 among adults from Iran.

In this cross-sectional study, the authors included 9,189 participants aged 20–70 who participated in the Yazd Health Study (YaHS) and Taghzieh Mardom-e-Yazd study (TAMIZ). They used factor analysis to extract dietary patterns based on a food frequency questionnaire (FFQ). Then, they assessed the relationship between these dietary patterns and the odds of COVID-19.

This study identified two major dietary patterns: “high protein and high fiber” and “transitional”. Participants in the highest tertile of the “high protein and high fiber” dietary pattern, which included vegetables, fruits, dairy and various kinds of meats such as red meat, fish and poultry, had a lower odds of COVID-19 compared with those in the lowest tertile. However, the “transitional” dietary pattern did not affect the risk of COVID-19.

In conclusion, a “high protein, high fiber” diet may lower the odds of COVID-19. This study suggests that dietary patterns may influence the severity and spread of future similar pandemics.
